Description

CROSS-REFERENCE TO RELATED APPLICATION



[0001] The present application claims a priority of a Chinese patent application No.201710128114.8 filed on March 6, 2017 in China, a disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD



[0002] The present disclosure relates to a field of transportation, and in particular, relates to a vehicle.

BACKGROUND



[0003] Usually, a body of a vehicle may be a unitary construction body or a separate frame construction body. A vehicle having the separate frame construction body includes a rigid frame (also called a chassis frame) and a vehicle body mounted on the rigid frame. In the vehicle having the separate frame construction body, such assembly components as an engine, a part of a transmission system and the vehicle body are all fixed onto the rigid frame through suspension systems, and the rigid frame are connected to wheels by means of front and rear suspension systems. Although the separate frame construction body has excellent stationarity and safety, the vehicle having the separate frame construction body is cumbersome, heavy and relatively high. Therefore, the separate frame construction body is usually used in a truck, a bus or an off-load vehicle, and is also used in some limousines.

[0004] A vehicle having the unitary construction body does not include a rigid frame. The unitary construction body includes a bottom plate, a roof and pillars connected between the bottom plate and the roof. The pillars include pillars A located at a front side of front doors of the vehicle, pillars B located between the front doors and rear doors of the vehicle, and pillars C located at a rear side of the rear doors. The bottom plate, the roof and the pillars of the unitary construction body form an integral structure. The engine, the front suspension systems for mounting front wheels, the rear suspension systems for mounting rear wheels, and a part of the transmission system are all mounted on the unitary construction body. The vehicle having the unitary construction body has such advantages as small mass, small height and being easily assembled. Therefore, the unitary construction body is used in most cars.

[0005] Each of the bottom plate and the roof of the unitary construction body includes a body structural member and a body cover panel covering the body structural member. Most body cover panels and body structural members are manufactured through a stamping forming process, and a size and a shape of the unitary construction body are influenced by a size and a shape of each of the body structural member and the body cover panels. When a type of a vehicle having the unitary construction body needs to be changed, various stamping dies for manufacturing the body structural members and the body cover panels need to be changed. Thus, a cost for changing the type of the vehicle having the unitary construction body is huge.

[0032] Fig.1 is an exploded view of a frame of a vehicle according to some embodiments of the present disclosure. Fig.2 is a structural schematic diagram of the vehicle according to some embodiments of the present disclosure. Fig.3 is a stereoscopic view of the vehicle according to some embodiments of the present disclosure.

[0033] Referring to Fig. 1, Fig. 2 and Fig. 3, the vehicle 1 includes a chassis 10 and a driving unit. The driving unit is arranged on the chassis 10 and configured to provide a driving force to wheels. The chassis 10 includes a chassis body 13, a front chassis modular unit 11 connected to a front end of the chassis body 13, and a rear chassis modular unit 12 connected to a rear end of the chassis body 13. A shape of the chassis body 13 in a longitudinal direction of the vehicle 1 is an elongate shape, e.g., a linear shape.

[0034] The front chassis modular unit 11 is connected to a pair of front wheels 73 through a front suspension system 71, and the rear chassis modular unit 12 is connected to a pair of rear wheels 74 through a rear suspension system 72.

[0035] One or two of the front chassis modular unit 11 and the rear chassis modular unit 12 are provided with a driving unit. If the front chassis modular unit 11 is provided with the driving unit, the vehicle 1 may be a front-wheel-drive vehicle. If the rear chassis modular unit 12 is provided with the driving unit, the vehicle 1 may be a rear-wheel-drive vehicle. If each of the front chassis modular unit 11 and the rear chassis modular unit 12 is provided with the driving unit, the vehicle 1 may be a four-wheel-drive vehicle. The vehicle 1 shown in some embodiments of the present disclosure may be the four-wheel-drive vehicle. In such a case, the driving unit arranged in the front chassis modular unit 11 may be called as a front driving unit 33, and the driving unit arranged in the rear chassis modular unit 12 may be called as a rear driving unit 34.

[0036] According to some embodiments of the present disclosure, the chassis 10 includes the chassis body 13 and a plurality of independent components including the front chassis modular unit 11 and the rear chassis modular unit 12 connected to the front end and the rear end of the chassis body 13. When vehicles with different wheelbases need to be manufactured, only one or more of the plurality of components of the chassis 10 need to be changed and connected sequentially to provide the chassis 10 with different wheelbases. In addition, a tread and a ground clearance of the vehicle may be changed by modifying a length of a suspension rocker-arm and a height of the suspension system on the chassis modular unit. As a result, a massive production of different types of vehicles may be achieved by using the chassis 10 of some embodiments of the present disclosure, and a cost for changing vehicle types is reduced.

[0037] The front chassis modular unit 11 includes a first housing 110. First through holes 111 are arranged in the first housing 110, and are configured to allow a first transmission device 61 to pass through the first through holes. The first transmission device 61 is configured to drive the pair of front wheels 73 to rotate. The first transmission device 61 extends from an interior of the first housing 110 to an exterior of the first housing 110 in a lateral direction of the vehicle. Ends of the first transmission device 61 away from the first housing 110 are connected to the pair of front wheels 73. As shown in Fig.8, the first transmission device 61 includes a first transmission shaft 610.

[0038] A first engine compartment 31 may be arranged inside the first housing 110 and be configured to accommodate the front driving unit 33 for driving the pair of front wheels 73. A support structure for supporting the front driving unit 33 may be further arranged on the first housing 110.

[0039] Fig.9 shows an external structure of the front driving unit 33 according to some embodiments of the present disclosure. The front driving unit 33 includes a first engine 331. Ends of the first transmission device 61 away from the pair of front wheels 73 cooperate with the front driving unit 33 in a transmissible manner so that the front driving unit 33 may drive the pair of front wheels 73 to rotate.

[0040] Optionally, a retarder, a differential mechanism and a gearbox (not shown) may be further arranged between the front driving unit 33 and the first transmission device 61.

[0041] In some embodiments of the present disclosure, a first connection component 112 is arranged at either side of the front chassis modular unit 11 and is detachably connected to a front suspension system 71 for supporting either of the pair of front wheels 73. As shown in Fig.11, the first connection component 112 is arranged on a side surface of the front chassis modular unit 11. The front suspension system 71 is connected to the first connection component 112, and extends away from the front chassis modular unit 11 in the lateral direction of the vehicle 1. Ends of the front suspension system 71 away from the front chassis modular unit 11 are connected to the pair of front wheels 73.

[0042] Fig.8 shows a schematic diagram of a front wheel and a front suspension system of the vehicle according to some embodiments of the present disclosure. As shown in Fig.8, the front suspension system 71 includes a plurality of first rods 711. A first end of each of the plurality of first rods 711 is connected to the first connection component 112 of the front chassis modular unit 11, and a second end of the each of the plurality of first rods 711 is connected to one of the pair of front wheels 73. At least a part of the plurality of first rods 711 are inclined relative to the lateral direction of the vehicle, so as to form a triangular stabilization structure.

[0043] A plurality of mounting portions 115 may be arranged on the first connection component 112. The plurality of mounting portions 115 is arranged in a radial direction of the first transmission device 61. First ends of the plurality of first rods 711 may be connected to different ones of the plurality of mounting portions 115, respectively so that the plurality of first rods 711 is inclined with different inclination angles relative to the lateral direction of the vehicle 1. In this way, vertical distances between second ends of the plurality of first rods 711 and the front chassis modular unit 11 are different, and thereby a length of the front suspension system 71 may be adjusted. Therefore, a distance between the pair of front wheels 73 may be adjusted.

[0044] Optionally, a plurality of second mounting portions 731 may be arranged on each of the pair of front wheels 73. The plurality of second mounting portions 731 is arranged in a radial direction of either of the front wheel 73 and may be configured to be connected to the second ends of the first rods 711, respectively. The second ends of the first rods 711 may be connected to different ones of the plurality of second mounting portions 731 so that inclination angles of the first rods 711 relative to the lateral direction of the vehicle 1 may be adjusted. In this way, the length of the front suspension system 71 and the distance between the pair of front wheels 73 may be adjusted.

[0045] Similarly, by adjusting mounting positions of both ends of each of the first rods 711 relative to the front chassis modular unit 11 and the front wheel 73, the ground clearance of the front chassis modular unit 11 may also be adjusted.

[0046] In this way, the length of the front suspension system of the vehicle in some embodiments of the present disclosure is adjustable so as to change the tread of the vehicle. Further, the ground clearance of the front chassis modular unit 11 of the vehicle 1 is also adjustable so as to change the ground distance of the vehicle 1. Hence, vehicles with different ground distances and different treads may be manufactured by simply adjusting the chassis 10 and the front suspension system 71 of the vehicle 1.

[0047] Of course, the chassis 10 of the vehicle may further cooperate with different front suspension systems 71 and different rear suspension systems 72, so as to change a width, the tread, and the ground clearance of the vehicle.

[0048] As shown in Figs.1 and 3, a height of a top surface of the first housing 110 of the front chassis modular unit 11 increases gradually from a foreside to a rear side, and the top surface of the first housing 110 smoothly transitions to a top surface of the chassis body 13, so as to provide the vehicle with a streamline shape. Optionally, the top surface of the first housing 110 smoothly transitions to a side surface of the first housing 110.

[0049] In some embodiments of the present disclosure, components of the chassis 10, such as the front chassis modular unit 11, the chassis body 13 and the rear chassis modular unit 12, may be made of an aluminum alloy. Two adjacent ones of the components of the chassis 10 may be connected to each other through a welding process, rivets or bolts.

[0050] In addition, the components of the chassis 10 may also be made of carbon fibers, and two adjacent ones of the components may be connected to each other through an adhesive or rivets. Optionally, one of the two adjacent components may be made of carbon fibers, the other of the two adjacent components may be made of an aluminum alloy, and the two adjacent components made of different materials may be connected to each other through the adhesive or rivets.

[0051] A cockpit 131 is arranged in the chassis body 13, and a width of the chassis body 13 is slightly greater than a width of the cockpit 131. A casing of the chassis body 13 includes two side walls 1310 spaced apart from each other in the lateral direction of the vehicle, and the cockpit 131 is formed between the two side walls 1310.

[0052] A power system cabin 132 is further arranged in the chassis body 13 and configured to accommodate a power system or any other components of the vehicle. The power system is configured to supply power to the driving units of the vehicle. In some embodiments of the present disclosure, the power system includes a power generation system, a power storage system (e.g., an accumulator), a power transmission system and/or a power control system. The power system cabin 132 is located behind the cockpit 131, and spaced apart from the cockpit 131 by a specific distance. Hence, by changing a distance between the power system cabin 132 and the cockpit 131, the length of the chassis body 13 may be changed, and thereby, the wheelbase of the vehicle may be changed.

[0053] Fig.3 is a stereoscopic diagram of the structure of the vehicle according to some embodiments of the present disclosure. Fig.4 is a structural schematic view of the rear chassis modular unit 12 according to some embodiments of the present disclosure. As shown in Figs.1, 3 and 4, the rear chassis modular unit 12 includes a second housing 122.

The second transmission device 62 extends from an interior of the second housing 122 to an exterior of the second housing 122 in the lateral direction of the vehicle. Ends of the second transmission device 62 away from the second housing 122 are connected to the pair of rear wheels 74 of the vehicle 1. As shown in Fig.10, the second transmission device 62 includes a second transmission shaft 620.

[0054] The second housing 122 includes a second engine compartment 32 configured to accommodate a rear driving unit 34 for driving the pair of rear wheels 74. The rear driving unit 34 is arranged inside the second housing 122. A support structure 123 for supporting the rear driving unit 34 is further arranged in the second housing 122.

[0055] In some embodiments of the present disclosure, the rear driving unit 34 includes a second electric motor 341. Ends of the second transmission device 62 away from the pair of rear wheels 74 cooperate with the rear driving unit 34 in a transmissible manner, so that the rear driving unit 34 may drive the pair of rear wheels 74 to rotate.

[0056] Optionally, a retarder, a differential mechanism and a gearbox (not shown) may also be arranged between the rear driving unit 34 and the second transmission device 62.

[0057] Fig. 12 shows a structural schematic diagram of second connection components arranged outside the rear driving unit according to some embodiments of the present disclosure. The second connection components 124 are arranged outside the rear driving unit 34 and are arranged at both sides of the rear chassis modular unit 12. Each of the second connection components 124 includes a plurality of third mounting portions 125. The plurality of third mounting portions 125 may be detachably connected to the rear suspension system 72 for supporting the pair of rear wheels 74. Ends of the rear suspension system 72 adjacent to the rear chassis modular unit 12 are connected to the second connection component 124, and extends away from the rear chassis modular unit 12 in the lateral direction of the vehicle 1. Other ends of the rear suspension system 72 away from the rear chassis modular unit 12 are connected to the pair of rear wheels 74.

[0058] The rear suspension system 72 includes a plurality of second rods 721. First ends of the second rods 721 are connected to the plurality of third mounting portions 125 on the second connection component 124, and second ends of the second rods 721 are connected to the rear wheel 74. At least a part of the second rods 721 are inclined relative to the lateral direction of the vehicle 1, so as to form a triangular stabilization structure.

[0059] Optionally, the plurality of third mounting portions 125 connected to the first ends of the second rods 721 may be arranged on the second housing 122 and may be arranged in the radial direction of the second transmission device 62. The first ends of the second rods 721 may be connected to different third mounting portions 125, so that inclination angles of the second rods 721 relative to the lateral direction of the vehicle 1 are different, and thereby, vertical distances between the second ends of the second rods 721 and the rear chassis modular unit 12 are different.
