Description

Field of the Technology

[0001] The present invention concerns a golf cart, and particularly concerns a motorized golf cart which is simple in construction and convenient in operation.

Background of the Technology

[0002] Existing golf carts are difficult to use no matter what motors or engines are used as a power source because of the configuration of the axle of the cart wheels and the output shaft of the motor or engine. This means when the cart is being manually pushed the rotation of the cart wheels will drive the output shaft of the power source to rotate together. When going up a slope the cart wheels are liable to slip if there is no power source to assist in pushing. This therefore makes it more difficult when pushing the cart manually, such as when the cart is being pushed over a short distance or when the electric energy of the accumulator battery has been exhausted. When a motor is employed for the golf cart as a power source to drive two wheels the rotor shaft of the motor, after speed reduction through the gear box, rotates the wheel axle thereby driving the two wheels. Construction of conventional golf carts means that the motor is not able to be at the same axial line as the wheel axle. It is therefore necessary to prepare other position to attach the motor, which makes the construction as a whole more detailed and complicated.

[0003] For existing golf carts, the height of its handle is typically fixed. During operation it is frequently necessary to regulate the height of the handle because of the differences in the height of the operators, therefore, problems of inconvenience in operation currently exist. Moreover, most of the existing handles of golf carts are straight,which makes them difficult to use for some people. This results in further problems of inconvenience in operation.

Summary of the Invention

[0004] An object of the present invention is to provide a motorized golf cart with simple construction and convenient operation, which solves problems of complicated construction, inconvenient operation, etc. of existing golf carts.

[0005] The object of the abovementioned technology of the present invention is to be solved by a golf cart including a bottom supporting frame, a front wheel located at the front lower end of bottom supporting frame, two rear wheels located at rear end of bottom supporting frame and a vertical supporting frame located on the bottom supporting frame, wherein the two rear wheels are driven by a driving motor. At the upper end of the vertical supporting frame is positioned a handle. At the front upper end of the bottom supporting frame there is fitted a front bag frame, and near the upper end of the vertical supporting frame there is fitted a rear bag frame. The centre of the hubs of the rear wheels include a one-way clutch, the center of the one-way clutch includes an axle hole, and the output end of the driving motor is mated-driven with the axle hole of the one-way clutch. When the golf cart wheels are driven through motor, etc. power source, the one-way clutches in cart wheels are mated, the cart wheel axle are driven by the power source thereby driving the corresponding wheel to move the golf cart across the ground. When no power source is being used, and the cart is being manually pushed, the wheels and the wheel axles are in a disengaged state of relative rotation, thus the cart can be pushed by the user. When the cart is pushed to go up a slope, its wheels can only turn in the upslope direction and its wheel axles are obstructed to turn by the friction of the motor in the downslope direction, thereby prevent its wheels from rolling downwardly, i.e. preventing the golf cart from slipping down the slope, while making it easy to push the cart up the slope.

[0006] As optimization, the one-way clutch includes an outer ring fixed with hub and inner ring set in the outer ring, the axle hole is set in the centre of the inner ring, the surface of the inner ring is equipped with several inclined flutes. In each inclined flute there is a roller, one side face of the inclined flute is a inclined plane which is inclined to one side along the turning direction of the outer ring and extended to the surface of the inner ring, the other side face is a straight plane approximately coinciding with the rotational face of the inner ring, the surface of the roller is equipped with friction teeth. When the roller is rolling to the surface of the inclined fillister, it takes the role of transferring the torque between the inner ring and the outer ring of the one-way clutch so as to make the hub fixed by the outer ring of the one-way clutch and the wheel axle fixed by the inner ring of the one-way clutch drive each other and then the power source of motor, etc. drives the wheels to roll and make the golf cart move. When the roller is located at the bottom end of the inclined flute, between the roller and the outer ring of the one-way clutch there is no touching or slipping thereby making the inner ring and the outer ring of the one-way clutch turn relatively. It is therefore easy for the use to cause the wheels to roll thereby making the cart easy to push.

[0007] As optimization, the driving motor (5) approximately coaxially alignes with two rear wheels (3) and includes a motor proper (51), rotor shafts (52) and tubular outer housing (53), the rotor shafts (52) respectively extended out of both ends of the tubular housing (53), and at both ends of the rotor shafts are respectively set gear boxes (55), each gear box is equipped with output shaft (54), the output shaft (54) mated with the axle hole (91) of one way clutch (9). At both ends of the motor are respectively fitted gear boxes wherein there are simultaneously two output ends which can be directly connected with wheels to drive wheels to turn. The motor can be coaxially set with wheels. Therefore, the arrangement of the motor becomes simpler when it is made as power source.

[0008] As optimization, the gear box includes a box body, box cover and counter shaft combination gear on the counter shaft, there are gear hobbings at the end of the rotor shaft which is engaged and driven with the combination gear of the counter shaft through the gear hobbings. The counter shaft gear hobbings are placed on the counter shaft which is engaged and are driven with the combination gears of the output shaft through the gear hobbings. In the gear box there are gears and gear hobbing transmission to make the arrangement of the gear box more compact so as to make the arrangement of the motor simple.

[0009] As optimization, a braking mechanism is fitted on the output shaft of one of the two gear boxes, the braking mechanism includes a rotational claw which is fixed with the output shaft to each other, a sliding claw which covers the outer surface of the output shaft and can make relative movement axially with the output shaft and the braking handle which can make the sliding claw move axially. The rotational claw and the sliding claw can be mated by means of the end face teeth. The smooth end of the output shaft near the sliding claw is covered with a ring block. Outside of the sliding claw and the ring block there is a braking seat. Between the sliding claw and the braking seat there is a reset spring. On the ring block is provided with a thread hole. After having mated with the thread of the braking seat, the braking handle enters into the thread hole of the ring block. There is approximately an elliptical hole between the sliding claw and the circular ring. In the elliptical hole there is a spheroid which is axially moved with the sliding claw relative to the ring block. When the handle is connected with the ring block through thread, the ring block is operated by the radial pressure from the end of the handle so as to make the steel ball in the circular hole positioned between the ring block and the sliding claw pressed toward outside surface of the ring block thereby pressing the sliding claw relative to the ring block, then occurs axial movement and mated with turning claw to prevent the output shaft from turning. When the radial pressure acting on the end of the handle is removed, the sliding claw resets as a result of the action of the reset spring, the sliding claw then is disengages with the turning claw, which allows free turning of the output shaft.

[0010] As optimization, a regulating mechanism is situated between the handle and a vertical frame. The regulating mechanism comprises the first end face gear which is fixed at the upper end of the vertical frame and the second end face gear which is fixed at the lower end of the handle. The end face teeth of the two end face gears are relatively set and connected together by means of a positioning pillar mated with a locking knob. The second end face gear is of hollow construction. In the chamber formed by the hollow construction of the second end face gear and the first end face gear there is a spring. The spring is covers the positioning pillar. Loosen the locking knob to make two end face gears in the state of relatively turning, turn the second end face gear to regulate the mating position of the end face gear of two end face gear, i.e. regulate the height of the handle fixed together to meet the requirement of different height operators. Easy in operation, it makes the design of the golf cart have more versatile. When regulating the height of the handle, loosen the locking knob. At function of the spring, the end faces of two end face gears are disengaged automatically, making it is easy in operation.

[0011] As optimization, a hinged support is set between the vertical supporting frame and the bottom supporting frame . The hinged support is of hollow circular pipe construction. At the upper end of the front side opening of the hinged support there is fillister. The lower end of the vertical supporting frame which is situated in front side opening of the hinged support is hinged with the hinged support. In the fillister near the upper end of the hinged support is arranged a sliding pin, which can be moved up and down with a tendency of moving downward due to the action of the spring. When the sliding pin is positioned in the fillister at the upper end of the hinged seat, the vertical supporting frame and hinged seat will be locked, the vertical supporting frame is vertically set on the bottom supporting frame of the golf cart. By pulling and moving the sliding pin upwardly the sliding pin disengages from the fillister at the upper end of the hinged seat. The vertical supporting frame can then be turned over so as to fold the vertical frame for convenient packing, transportation, and storage.

[0012] As optimization the front bag frame is of a compact construction. The handle, the vertical supporting frame, the bottom frame and the rear covered frame is of hollow circular pipe construction. The bottom supporting frame is constructed by a left longitudinal supporting frame and right longitudinal supporting frame left/right-symmetrical and parallel-aligned at a same level. The arrangement makes the golf cart as a whole simple in construction.

[0013] As optimization, a switch box is provided on the handle which is composed of a vertical handle and a transverse handle. The vertical handle is connected with the vertical supporting frame. It is more convenient to operate for the switch box setting on the handle. The handles are designed into a vertical handle and a transverse handle which is in a T-shaped configuration for grasping easily by left/right hands to meet the habits of different operators.

[0014] Therefore, this present invention has features of simple construction and convenient operation. When the golf cart wheels are driven through motor, etc. power source, the one-way clutches in cart wheels are mated, the cart wheel axle is driven by power source thereby rotating the wheels to move the golf cart. When no power source is used and the cart is pushed manually the wheels and the wheel axles are in a disengaged state of relative rotation, thus the cart can be pushed manually by the operator. When the cart is pushed to go up a slope, its wheels can only turn in the forward upslope direction and its wheel axles are obstructed from turning in the downslope direction by the friction of the motor, thereby preventing its wheels from rolling in a down slope direction, i.e. the configuration prevents the golf cart from slipping down the slope, while making it easy to push the cart up the slope. The tubular motor is adopted, such that at both ends of the motor are respectively fitted gear boxes wherein there are simultaneously two output ends which can be directly connected with wheels to drive wheels to turn. The motor can be coaxially aligned with wheels. Therefore, the arrangement of the motor becomes compact when it is made as the power source.
