Description

Technical Field

[0001] The utility model relates to the technical field of mobile devices, in particular to a driving device for a four-wheeled vehicle. Background Art

[0002] At present, a four-wheeled cart is a means of transportation with four wheels. This type of cart is usually used in factories, warehouses and other production places for cargo transportation, material handling and other tasks. The design of the four-wheeled cart enables it to travel on different terrains and grounds, improving work efficiency and convenience. Due to the wide use of four-wheeled carts, the optimization of the four-wheeled cart is necessary.

[0003] A four-wheeled independently driven vehicle is disclosed in a Chinese utility model patent with announcement number CN207157335U. In the above prior art, although an axial shock absorber is provided between the independently driven components, precise position control can be performed on a road surface with certain undulations, but an uneven road surface will cause a certain vibration of the four-wheeled vehicle when it moves, and the vibration will also cause the battery that provides power to the four-wheeled vehicle to vibrate. Repeated vibrations will cause the plates inside the battery to loosen, and will also cause the connection between the battery and the four-wheeled vehicle motor to be unstable, and even cause a short circuit, thereby affecting the life of the battery. Therefore, it is necessary to design a drive device for a four-wheeled vehicle that can provide shockproof protection for the battery when the four-wheeled vehicle is in use. Utility Model Content

[0004] In order to solve the technical problem that repeated vibrations will cause the internal battery of the four-wheeled vehicle to vibrate, resulting in unstable connection between the battery and the drive motor and affecting the battery life, the utility model provides a drive device for the four-wheeled vehicle.

[0005] The utility model is implemented by the following technical scheme: a driving device for a four-wheeled vehicle, comprising a four-wheeled vehicle, a driving component for driving the four-wheeled vehicle to move is provided at the bottom of the four-wheeled vehicle, a power supply component for supplying power to the driving component is provided on one side of the driving component, a shock absorbing component for reducing battery vibration is provided inside the power supply component, adjustment components for adjusting the position of the shock absorbing component according to the size of the battery are provided on both sides of the shock absorbing component, and anti-sway components for limiting the position of the internal battery and preventing sway are provided on both sides of the inner wall of the power supply component.

[0006] Through the above technical solution, when the four-wheeled vehicle moves, the shock-absorbing component will reduce the vibration of the vehicle, thereby reducing the vibration transmitted to the battery pack, and the anti-sway component will prevent the vibration from causing displacement of the battery pack.

[0007] As a further improvement of the above solution, an installation opening penetrating the four-wheel trolley is provided on one side of the four-wheel trolley. The power supply assembly includes a power supply box fixedly installed inside the installation opening, a battery pack arranged inside the power supply box, and a cover plate arranged at the opening of the power supply box.

[0008] Through the above technical solution, when the battery pack has been used for too long, it can be replaced, and battery packs of different sizes can be replaced.

[0009] As a further improvement of the above solution, the shock absorption assembly includes two shock absorption plates arranged at the bottom of the battery pack and limiting plates fixedly installed on both sides of each shock absorption plate.

[0010] Through the above technical solution, the battery pack presses on the two shock absorption plates, and the gap in the middle and the two shock absorption plates will reduce the vibration more.

[0011] As a further improvement of the above solution, the adjustment assembly includes a bidirectional threaded rod arranged between two adjacent limiting plates, a first gear fixedly sleeved on the bidirectional threaded rod, a second gear arranged on one side of the first gear, and a synchronous belt sleeved on the first gear and the second gear. First rotating blocks are fixedly installed on both sides of the second gear, and connecting plates fixedly installed on the inner wall of the power supply box are rotatably installed on one side of each of the two first rotating blocks. Both ends of the bidirectional threaded rod threadedly penetrate through the adjacent limiting plates and are fixedly installed with second rotating blocks, and both of the second rotating blocks are rotatably installed on the inner wall of the power supply box.

[0012] Through the above technical solution, pulling the synchronous belt will cause the first gear to rotate, thereby driving the two limiting plates to move by the bidirectional threaded rod and adjusting the positions of the two shock absorption plates.

[0013] As a further improvement of the above solution, the anti-shake assembly includes a sliding plate fixedly installed on one side of the inner wall of the power supply box and provided with a sliding groove, a sliding block slidably installed inside the sliding groove, and a limiting plate fixedly installed on one side of the sliding block.

[0014] Through the above technical solution, the limiting plate cooperating with the battery pack can be replaced.

[0015] As a further improvement of the above solution, the limiting plate is arranged in a "C" shape, and one side of the limiting plate is attached to the battery pack.

[0016] Through the above technical solution, the limiting plate will block the shaking of the battery pack.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] The utility model provides a power supply component, a shock absorbing component, an adjustment component and an anti-sway component. When the power supply component supplies power to the four-wheeled vehicle, the shock absorbing component will reduce the vibration generated by the movement of the four-wheeled vehicle to avoid multiple vibrations making the power supply connection between the battery pack and the driving component unstable. The adjustment component can adjust the position of the shock absorbing component according to the size of the battery pack to avoid the shock absorbing effect being reduced due to the inability to move the shock absorbing component after the battery packs of different sizes are replaced at a later time. The anti-sway component will block the movement of the battery pack when it moves due to vibration to prevent the battery pack from moving and causing an unstable connection. This arrangement can not only reduce the shock of the battery pack, make the connection between the battery pack and the driving component more stable and extend the service life, but also adjust the shock absorbing component and the anti-sway component after replacing the battery packs of different sizes, so as to reduce the shock and prevent the battery packs of different sizes from swaying.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 A driving device for a four-wheeled vehicle in this embodiment includes a four-wheeled vehicle 1. A driving component 2 for driving the four-wheeled vehicle 1 to move is provided at the bottom of the four-wheeled vehicle 1. A power supply component for supplying power to the driving component 2 is provided on one side of the driving component 2. A shock absorbing component for reducing battery vibration is provided inside the power supply component. Adjustment components for adjusting the position of the shock absorbing component according to the size of the battery are provided on both sides of the shock absorbing component. Anti-sway components for limiting the position of the internal battery and preventing sway are provided on both sides of the inner wall of the power supply component.

[0026] Combined with Figure 1 and Figure 2 , an installation opening penetrating through the four-wheel cart 1 is provided on one side of the four-wheel cart 1. The power supply assembly includes a power supply box 301 fixedly installed inside the installation opening, a battery pack 302 arranged inside the power supply box 301, and a cover plate 303 arranged at the opening of the power supply box 301. When the battery pack 302 has been used for too long, it can be replaced, and battery packs 302 of different sizes can be replaced.

[0027] Combined with Figure 2 and Figure 3 , the shock absorption assembly includes two shock absorption plates 401 arranged at the bottom of the battery pack 302 and limiting plates 402 fixedly installed on both sides of each shock absorption plate 401. The shock absorption plates 401 are made of rubber. The battery pack 302 is pressed on the two shock absorption plates 401, and the middle gap and the two shock absorption plates 401 will reduce the vibration more.

[0028] Combined with Figure 2 and Figure 3 , the adjustment assembly includes a bidirectional threaded rod 501 arranged between two adjacent limiting plates 402, a first gear 502 fixedly sleeved on the bidirectional threaded rod 501, a second gear 503 arranged on one side of the first gear 502, and a synchronous belt 504 sleeved on the first gear 502 and the second gear 503. First rotating blocks 7 are fixedly installed on both sides of the second gear 503. A connecting plate 8 fixedly installed on the inner wall of the power supply box 301 is rotatably installed on one side of each of the two first rotating blocks 7. Both ends of the bidirectional threaded rod 501 threadedly penetrate through the adjacent limiting plates 402 and are fixedly installed with second rotating blocks 9. Both of the two second rotating blocks 9 are rotatably installed on the inner wall of the power supply box 301. Pulling the synchronous belt 504 will cause the first gear 502 to rotate, thereby driving the two limiting plates 402 to move by the bidirectional threaded rod 501 and adjusting the positions of the two shock absorption plates 401.

[0029] Combined with Figure 2 , the anti-shake assembly includes a sliding plate 601 fixedly installed on one side of the inner wall of the power supply box 301 and provided with a sliding groove, a sliding block 602 slidably installed inside the sliding groove, and a limiting plate 603 fixedly installed on one side of the sliding block 602. The limiting plate 603 is arranged in a "C" shape, and one side of the limiting plate 603 is attached to the battery pack 302, and the limiting plate 603 will block the shaking of the battery pack 302.

[0030] The implementation principle of a driving device for a four-wheeled vehicle in the embodiment of the present application is as follows: when the battery pack 302 supplies power to the driving component 2 and allows the four-wheeled vehicle 1 to move, the movement of the four-wheeled vehicle 1 generates vibration, which will be transmitted to the power supply box 301 and then to the shock-absorbing plate 401. The two shock-absorbing plates 401 are used to raise the battery pack 302 so that the middle part of the battery pack 302 is suspended. The two shock-absorbing plates 401 can already provide a certain degree of shock absorption to the battery pack 302, and the suspended part will increase the shock absorption effect, so the shock absorption effect on the battery pack 302 is better, and the two limit plates 603 are in contact with the battery pack 302 to limit the position of the battery pack 302 to prevent multiple slight vibrations from causing the battery pack 302 to be displaced, thereby affecting the shock absorption effect. When the battery pack 302 is replaced with a different size at the end of its service life When the battery pack 302 is replaced, the second gear 503 is rotated, which will cause the synchronous belt 504 to pull the first gear 502 to rotate, thereby causing the bidirectional threaded rod 501 to rotate, and finally the two limiting plates 402 pull the shock-absorbing plate 401 to move to adapt to the shock-absorbing position of the replaced battery pack 302. At the same time, the limit plate 603 can be moved out of the power supply box 301 in cooperation with the sliding block 602, and the limit plate 603 adapted to the current battery pack 302 can be replaced and then inserted into the sliding groove of the sliding plate 601 to limit the battery pack 302. This setting can not only reduce the shock of the battery pack 302, but also make the connection between the battery pack 302 and the drive component 2 more stable and extend the service life. After replacing battery packs 302 of different sizes, the shock-absorbing component and the anti-sway component can be adjusted, so that battery packs 302 of different sizes can also be shock-absorbing and anti-sway.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
