Description

Technical Field

[0001] This utility model relates to the field of golf cart drive wheel technology, specifically an integrated drive wheel for golf carts. Background Technology

[0002] With the development of electrification, more and more golf carts are adopting electric drive. During operation, there are no exhaust emissions, low noise, and they are environmentally friendly. Compared with traditional fuel vehicles, electric vehicles reduce air pollution and noise interference, providing a quieter and more comfortable environment for golf courses and residential areas. The stability of the electric drive tires is directly related to the stability of the entire vehicle.

[0003] For example, patent CN218402315U discloses an integrated drive wheel structure, including a bracket, a motor assembly, and a wheel body. The bracket has a support portion, and the wheel body is rotatably mounted outside the support portion. The support portion has a through cavity. The motor assembly includes a stator fixed to the inner wall of the cavity, and a rotor is disposed inside the cavity. One end of the rotor's shaft is rotatably connected to the bracket and extends out of one side of the bracket. A half-shell is fixed to one end of the support portion, and the other end of the shaft is rotatably connected to the half-shell. The end of the shaft extending out of the bracket is connected to the wheel body via a gear set for transmission. A gear cover is provided on the side of the bracket facing away from the support portion, and the bracket is equipped with a gear cover... The gear cover is fixed to the mating plane and encloses the gear set inside. The gear cover has a shaft hole corresponding to the position of the rotating shaft. The rotating shaft passes through the shaft hole and extends out of the gear cover. A brake is provided at the end of the rotating shaft. The brake is fixed to the gear cover, which can reduce the cost of the motor and make the structure more reasonable. In order to maintain the stability of electric drive operation, some existing golf carts usually have a reduction mechanism, such as a speed reducer, in the electric drive. However, the reduction structure is large in size, which occupies the space of the electric drive structure, increases the overall thickness of the electric drive part, and increases the size of the running drive wheel, which is not conducive to the flexible rotation of the drive wheel.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing golf cart drive wheels. Utility Model Content

[0005] The purpose of this invention is to provide an integrated drive wheel for golf carts, in order to solve the problem mentioned in the background art that the deceleration structure is large in size, occupies the space of the electric drive structure, increases the overall thickness of the electric drive part, and thus increases the size of the driving wheel, which is not conducive to the flexible rotation of the driving wheel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated drive wheel for a golf cart, comprising a connecting rod connected to the golf cart frame, an inner shell fixedly fitted at the end of the connecting rod away from the frame, an outer shell rotatably fitted around the inner shell, and a large bearing installed between the inner shell and the outer shell, multiple spokes arranged at equal angles along the axis of the connecting rod on the outer side of the outer shell, and wheels fixedly installed on the outer side of the multiple spokes; a power mechanism for driving the rotation of the outer shell is provided in the inner shell.

[0007] Preferably, the power mechanism includes a stator fixedly installed inside the inner housing, and a rotor is rotatably installed in the inner housing along the axial direction, with the rotor correspondingly disposed inside the stator.

[0008] Preferably, a control circuit board is installed in the inner housing, and the connecting rod is provided with a circuit groove for connecting the control circuit board to the wiring.

[0009] Preferably, the inner housing is provided with a deceleration mechanism for controlling the deceleration rotation of the outer housing; the power mechanism and the deceleration mechanism are integrated in the inner housing, which enables the wheel to decelerate directly through the meshing transmission of the pinion and reduction gear when the rotor rotates and outputs power, thereby reducing the thickness of the integrated drive wheel and maintaining the flexibility and stability of the electric drive operation of the integrated drive wheel.

[0010] Preferably, the deceleration mechanism includes a rotating shaft rotatably mounted in the inner housing, and a small bearing is installed between the rotating shaft and the inner housing.

[0011] Preferably, the reduction mechanism further includes a plurality of small gears rotatably mounted on the outside of the rotating shaft at equal angles, and the small gears are externally meshed with reduction gears; the small gears follow the circumference of the rotating shaft, and the rotating shaft is coaxially and fixedly connected to the rotor.

[0012] Preferably, a cover plate is sealed and installed on the outer shell, the cover plate is rotatably connected to the bottom of the inner shell, and the cover plate is fixedly connected to the reduction gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the golf cart uses an integrated drive wheel, and the power mechanism and the deceleration mechanism are both set in the inner shell. While maintaining the deceleration control of the wheel rotation, the overall space occupied is small, which reduces the thickness of the integrated drive wheel and makes it more flexible to rotate.

[0014] Furthermore, the inner housing is equipped with a power mechanism that drives the outer housing to rotate. When energized, the rotor is connected to the inner housing and rotates, providing the original power for the tire rotation.

[0015] Furthermore, the inner housing is equipped with a deceleration mechanism that controls the deceleration rotation of the outer housing. The rotation of the rotor drives the rotating shaft to rotate synchronously. The small gear outside the rotating shaft meshes with the reduction gear. Under the meshing transmission, the reduction gear and the cover plate can be controlled to decelerate and rotate. The cover plate drives the outer housing to decelerate and rotate, thereby driving the wheels to decelerate and rotate stably. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-3 The present invention provides the following technical solution: an integrated drive wheel for a golf cart, comprising a connecting rod 1 connected to the golf cart frame, an inner shell 2 fixedly fitted at the end of the connecting rod 1 away from the frame, an outer shell 3 rotatably fitted outside the inner shell 2, and a large bearing 6 installed between the inner shell 2 and the outer shell 3, and multiple spokes 4 arranged at equal angles along the axis of the connecting rod 1 on the outside of the outer shell 3, and wheels 5 fixedly installed on the outside of the multiple spokes 4; a power mechanism for driving the rotation of the outer shell 3 is provided in the inner shell 2.

[0022] The power mechanism includes a stator 9 fixedly installed inside the inner housing 2, and a rotor 10 rotatably installed in the inner housing 2 along the axial direction, with the rotor 10 correspondingly arranged inside the stator 9.

[0023] The inner housing 2 contains a control circuit board 8, and the connecting rod 1 has a circuit groove 7 for connecting the control circuit board 8 to the wiring.

[0024] The connecting rod 1 is installed on the frame of the golf cart. The frame is equipped with a power supply. The power line is connected to the control circuit board 8 in the inner housing 2 through the circuit slot 7. When the control circuit board 8 is energized, the rotor 10 rotates inside the stator 9, providing the original power for the rotation of the wheel 5.

[0025] Example 2: Based on Example 1, a deceleration mechanism is also disclosed, the specific structure of which is as follows: A deceleration mechanism for controlling the deceleration rotation of the outer shell 3 is provided in the inner shell 2. The deceleration mechanism includes a rotating shaft 12 rotatably installed in the inner shell 2, and a small bearing 11 is installed between the rotating shaft 12 and the inner shell 2.

[0026] The reduction mechanism also includes multiple pinions 13 that are rotatably mounted on the outside of the rotating shaft 12 at equal angles. The pinions 13 are externally meshed with reduction gears 14. The pinions 13 follow the circumference of the rotating shaft 12, and the rotating shaft 12 is coaxially and fixedly connected to the rotor 10.

[0027] A cover plate 15 is sealed and installed on the outer shell 3. The cover plate 15 is rotatably connected to the bottom of the inner shell 2, and the cover plate 15 is fixedly connected to the reduction gear 14.

[0028] When the rotor 10 rotates in the inner housing 2, it drives the rotating shaft 12 in the inner housing 2 to rotate synchronously. Multiple sets of small gears 13 are provided on the outside of the rotating shaft 12. When the rotating shaft 12 rotates, the small gears 13 on its outside rotate circumferentially along the axis of the rotating shaft 12. The multiple sets of small gears 13 are meshed and connected to the inner side of the reduction gear 14. Under the meshing transmission, the reduction gear 14 is decelerated and rotates. The reduction gear 14 is connected to the outer housing 3 through the cover plate 15. When it rotates, it can drive the outer housing 3 to rotate at a reduced speed, thereby achieving the purpose of driving the outer housing 3, spokes 4 and wheels 5 to rotate by electricity.

[0029] Since the reduction mechanism, such as the rotating shaft 12, pinion 13 and reduction gear 14, is set in the inner housing 2, it is combined with the power mechanism of the electric drive. During the process of the rotor 10 outputting power, the reduction can be achieved by the meshing transmission of the pinion 13 and reduction gear 14. There is no need to install a reduction device outside the electric drive equipment, which reduces the thickness of the integrated drive wheel and enables the drive wheel to drive flexibly.
