Description

Technical Field

[0001] The invention relates to the technical field of batteries, and in particular to a wheel hub motor with high adaptability. Background Art

[0002] The wheel hub motor is a motor system that directly mounts the motor on the wheel hub. This design makes the vehicle structure simpler and lighter, while also improving the overall efficiency and performance of the vehicle. The wheel hub motor mainly uses electricity to drive the wheels to rotate, thereby driving the entire vehicle.

[0003] Hub motors are widely used in self-balancing scooters, which are a new type of personal electric tool that controls the vehicle's forward, backward, left and right turns by leaning forward or backward.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

The motor rotor with the tire constitutes the wheel structure of the balance vehicle. According to actual needs, wheels of different sizes can be more freely selected on the balance vehicle. At the same time, the motor rotor is connected to the motor stator through an outer hub cover and an inner hub cover of corresponding sizes.

When inner hub covers of different sizes are added to the motor stator, the telescopic rod can be extended or shortened so that its end is connected to the clamping sleeve on the inner hub cover, and then the driving rope is pulled or loosened to drive the driven rope to move in the center tube, and then the transfer rope is further pulled to drive the movable part on the counterweight seat to move in the opposite direction. At the same time, the movement of the movable part is transmitted to the counterweight block through the push-pull structure, and the push-pull structure has a distance-increasing effect, so the change in the wheel hub size is amplified and reflected in the movement of the counterweight block, and the center of gravity position of the hub motor is adjusted by the movement of the counterweight block. The specific amplification ratio depends on the ratio of the small gear to the large gear.

[0019] 3. The counterweight block of the present invention is further provided with an additional weight structure.

[0034] The hub motor of the present invention utilizes the motor stator 1 as an unchanging core component, and sets the motor rotor 2 as a modifiable component. The motor rotor 2 with the tire 5 constitutes the wheel structure of the balance vehicle. According to actual needs, wheels of different sizes can be more freely selected on the balance vehicle. At the same time, the motor rotor 2 is connected to the motor stator 1 through an outer hub cover 3 and an inner hub cover 4 of corresponding sizes.

[0036] The motor stator 1 is installed on the guide tube on the side facing the inner hub cover 4, and is fixed on the center seat 13 by using the first connecting piece 7 on the guide tube. The center seat 13 can be installed in the body of the balance vehicle through the bracket 16. Therefore, the hub motors are arranged on both sides of the balance vehicle for support and driving.

[0037] A guide tube is provided in the fixed sleeve 6, and a hinge seat is provided on the outer wall of the fixed sleeve 6. The bottom of the telescopic rod 8 is connected to the hinge seat. The telescopic rod 8 is composed of a fixed rod and a movable rod. The driving rope 9 passes through the fixed rod and the hinge seat and enters the guide tube. A clamping structure is provided in the clamping sleeve 12 to connect the telescopic rod 8.

[0038] The present invention installs a driving rope 9 for adjusting the center of gravity position on the fixing sleeve 6, and the driving rope 9 is installed relying on the telescopic rod 8. When inner hub covers 4 of different sizes are installed on the motor stator 1, the telescopic rod 8 can be extended or shortened so that its end is connected to the clamping sleeve 12 on the inner hub cover 4, and then the driving rope 9 is pulled or loosened, so that the center of gravity position of the hub motor is automatically adjusted.

[0039] A first hanger 10 is fixedly connected to the driving rope 9 , one end of the driven rope 18 is connected to a second hanger 19 , the driving rope 9 and the driven rope 18 are connected via the first hanger 10 and the second hanger 19 , and the other end of the driven rope 18 is connected to the drive rope 20 .

[0040] The driving rope 9 is connected to the driven rope 18 through the first hanger 10 and the second hanger 19. Taking the replacement of the inner hub cover 4 with a larger size as an example, as the telescopic rod 8 is extended, the driving rope 9 is pulled, and after being guided by the hinge seat and the guide tube, the driven rope 18 can be pulled to move in the central tube 17, thereby further pulling the drive rope 20.

[0041] The center seat 13 and the counterweight seat 14 are installed in the balance vehicle through the bracket 16, the steering wheel 21 is installed in the cavity of the center seat 13, a slide groove is provided between the center seat 13 and the counterweight seat 14, and the movable part 22 is connected to the slide groove. Two transfer ropes 20 are provided, and the steering wheels 21 are located on both sides of the end of the center tube 17. One end of the transfer rope 20 is connected to the driven rope 18, and the other end is connected to the movable part 22.

[0042] The transfer rope 20 can be turned by the steering wheel 21, so as to more reasonably utilize the space in the center seat 13. When the transfer rope 20 is pulled, the movable part 22 on the counterweight seat 14 can be driven to move in the opposite direction.

[0043] The push-pull structure includes a first rack 23 mounted on the movable member 22 and a second rack 26 mounted on the counterweight 24, and the first rack 23 and the second rack 26 are arranged at a height offset. The pushing structure also includes a wheel shaft 29 vertically arranged in the cavity of the counterweight seat 14, and a small gear 27 and a large gear 28 are coaxially mounted on the wheel shaft 29, and the small gear 27 and the large gear 28 are meshed with the first rack 23 and the second rack 26 respectively.

[0044] The present invention transmits the movement of the movable part 22 to the counterweight 24 through a push-pull structure, and the push-pull structure has a distance-increasing effect, so the change in the wheel hub size is amplified and reflected in the movement of the counterweight 24. The center of gravity position of the hub motor is adjusted by the movement of the counterweight 24, and the specific amplification ratio depends on the ratio of the small gear 27 and the large gear 28.

[0045] When the wheel hub size becomes larger, the movable part 22 can drive the first rack 23 to move, thereby causing the pinion 27 to rotate. Since the large gear 28 and the small gear 27 are coaxially installed, the two have the same angular velocity, and the large gear 28 has a larger diameter and therefore has a larger linear velocity, and the second rack 26 is driven to increase the distance, so that the counterweight block 24 overcomes the elastic force of the limit spring 25 and moves, so as to distribute the center of gravity of the hub motor more evenly. Conversely, when the wheel hub size becomes smaller, the center of gravity of the hub motor can also be adjusted accordingly.

[0046] A guide groove is provided in the counterweight seat 14, and the counterweight block 24 is slidingly installed in the guide groove.

[0048] When in use, the wheel hub motor of the present invention utilizes the motor stator 1 as an unchanging core component, and sets the motor rotor 2 as a refittable component. The motor rotor 2 with the tire 5 constitutes the wheel structure of the balance vehicle. According to actual needs, wheels of different sizes can be more freely selected on the balance vehicle. At the same time, the motor rotor 2 is connected to the motor stator 1 through an outer hub cover 3 and an inner hub cover 4 of corresponding sizes. The size change of the inner hub cover 4 can constitute a guide for adjusting the center of gravity position of the entire wheel hub motor. The motor stator 1 is installed with a guide tube on one side facing the inner hub cover 4, and is fixedly installed on the center seat 13 using the first connecting piece 7 on the guide tube, and the center seat 13 can be installed in the main body of the balance vehicle through a bracket 16. The hub motors are arranged on both sides of the balancing car for support and driving. A driving rope 9 for adjusting the center of gravity position is installed on the fixed sleeve 6. The driving rope 9 is installed on the telescopic rod 8. When inner hub covers 4 of different sizes are installed on the motor stator 1, the telescopic rod 8 can be extended or shortened so that its end is connected to the clamping sleeve 12 on the inner hub cover 4, and then the driving rope 9 is pulled or loosened, so that the center of gravity position of the hub motor is automatically adjusted. The driving rope 9 is connected to the driven rope 18 through the first pendant 10 and the second pendant 19. Taking the replacement of the inner hub cover 4 of a larger size as an example, as the telescopic rod 8 is extended, the driving rope 9 is pulled, and after being guided by the hinge seat and the guide tube, the driven rope 9 can be pulled from the hub cover 4. The moving rope 18 moves in the center tube 17, and then further pulls the transfer rope 20. The transfer rope 20 can be turned by the steering wheel 21, and the space in the center seat 13 is used more reasonably. When the transfer rope 20 is pulled, the movable part 22 on the counterweight seat 14 can be driven to move in the opposite direction. The present invention transmits the movement of the movable part 22 to the counterweight block 24 through a push-pull structure, and the push-pull structure has a distance-increasing effect, so the change in the wheel hub size is amplified and reflected in the movement of the counterweight block 24. The center of gravity position of the wheel hub motor is adjusted by the movement of the counterweight block 24. The specific amplification ratio depends on the ratio of the small gear 27 and the large gear 28. When the wheel hub size becomes larger, the movable part 22 can drive the first rack 23 to move. , thereby causing the pinion 27 to rotate. Since the large gear 28 and the small gear 27 are coaxially installed, the two have the same angular velocity, and the large gear 28 has a larger diameter and therefore has a larger linear velocity, and the second rack 26 is driven to increase the distance, so that the counterweight block 24 overcomes the elastic force of the limit spring 25 and moves to distribute the center of gravity of the hub motor more evenly. Conversely, when the wheel hub size becomes smaller, the center of gravity of the hub motor can also be adjusted accordingly. The counterweight block 24 is further provided with an additional weight structure. According to the weight of other parts of the balancing vehicle, the counterweight can be added or subtracted on the additional plate 30 of the counterweight block 24 to enhance the center of gravity adjustment ability of the counterweight block 24, so that the hub motor has stronger adaptability.
