Description

Technical Field

[0001] This utility model relates to the field of electric vehicle safety protection technology, and in particular to an anti-accidental contact device for the rear wheel of an electric vehicle. Background Technology

[0002] Electric vehicles, as an environmentally friendly and convenient means of transportation, have been widely used in urban transportation due to their low operating costs and ease of driving. While electric vehicles have made travel more convenient, their safety has also attracted increasing attention.

[0003] The rear wheel area of ​​electric vehicles is usually exposed, which makes it easy for accidental contact accidents to occur, especially when children come into contact with it, posing a significant safety hazard. Traditional electric vehicle rear wheel protection structures are mostly simple, often simply fixing mudguards or protective covers directly to the outside of the rear wheel, with limited protective effect. Moreover, when the rear wheel is being inspected or replaced, the protective structure will obstruct the view and operation. Therefore, it is necessary to remove the protective structure before carrying out related work, which is quite inconvenient.

[0004] Therefore, given the limited protective effect and inconvenient disassembly and assembly of existing electric vehicle rear wheel protection structures, a device to prevent accidental contact with the rear wheel of an electric vehicle can be designed. This device uses an openable and closable protection method to ensure that the rear wheel is fully protected, preventing accidental contact and improving the safety of electric vehicle use. The position of the protection structure can be flexibly adjusted according to actual operational needs, eliminating the need to remove the protection structure when inspecting the rear wheel, thus speeding up the inspection process and effectively enhancing the practical value of the device. Utility Model Content

[0005] In order to overcome the problem that most electric vehicle rear wheel protection structures are often fixed directly to the outside of the rear wheel with mudguards or protective covers, which have limited protective effect, and that the protective structure can obstruct the view and operation when the rear wheel is inspected or replaced, requiring the protective structure to be removed before related work can be carried out, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: an anti-accidental contact device for the rear wheel of an electric vehicle, comprising a rear wheel body, a connecting shaft, a frame body, a protective top cover, a lifting assembly, protective side covers, an opening and closing assembly, and a through groove. A connecting shaft is provided in the middle of the rear wheel body, and both ends of the connecting shaft are fixedly connected to the inner bottom of the frame body. A lifting assembly is provided on the inner side of the frame body, and a protective top cover is provided on one side of the lifting assembly. Two sets of protective side covers are symmetrically provided at both ends of the outer side of the protective top cover. An opening and closing assembly is provided at the top of the protective side cover, and a through groove is provided in the middle of the protective side cover.

[0007] Preferably, the rear wheel body is rotatably connected to the frame body via a connecting shaft, thereby fixing the rear wheel body to the frame body. A protective top cover protects the top of the rear wheel body to prevent mud and sand from splashing, while protective side covers protect both sides of the rear wheel body. The protective side covers penetrate the frame body through a through groove, thus providing comprehensive physical isolation and protection for the rear wheel body to prevent accidental contact. The height of the protective top cover and protective side covers can be flexibly adjusted using a lifting component, and the protective side covers can be flexibly unfolded using an opening and closing component. This ensures that the rear wheel is fully protected, preventing accidental contact by personnel and improving the safety of electric vehicle use. The ability to flexibly adjust the position of the protective structure according to actual operational needs enhances the practical value of the device.

[0008] Preferably, the rear wheel body is rotatably connected to the connecting shaft, the protective top cover is set above the rear wheel body, the protective top cover is fitted to the top shape of the rear wheel body, and the bottom of the frame body passes through the protective side cover through a through groove.

[0009] Preferably, the lifting assembly includes a lifting mechanism, which is provided on the inner side of the frame body. The lifting mechanism adopts any one of the following: ball screw, electric push rod, electric cylinder, linear motor, cylinder mechanism or hydraulic cylinder.

[0010] Preferably, the lifting assembly includes a drive motor and a connecting block. The drive motor is located at the bottom of the frame body, and the connecting block is located on the outside of the lifting mechanism. The bottom of the outer side of the protective top cover is fixedly connected to the connecting block.

[0011] Preferably, the drive motor is electrically connected to the electric vehicle control mechanism, and the output end of the drive motor is electrically connected to the drive mechanism of the lifting mechanism, and the connecting block moves linearly through the lifting mechanism.

[0012] Preferably, the opening and closing assembly includes a fixing plate, and two sets of fixing plates are symmetrically arranged at both ends of the outer side of the protective top cover. The fixing plates are arranged in pairs and are located on both sides of the frame body.

[0013] Preferably, the opening and closing assembly also includes a rotating shaft and damping pads. The rotating shaft is rotatably connected between the two sets of fixed plates. The top of the protective side cover is located on the outside of the rotating shaft, and damping pads are provided at both ends of the rotating shaft.

[0014] The beneficial effects of this utility model are:

[0015] During driving, the main frame is connected to a fixed connecting shaft, and the rear wheel rotates around the connecting shaft to ensure normal driving of the electric vehicle. The top of the rear wheel is protected by a protective top cover to prevent mud and sand from splashing. The protective side cover passes through the main frame via a through groove, protecting both sides of the rear wheel, thus providing comprehensive physical isolation and protection for the rear wheel and preventing accidental contact. During maintenance, the protective side cover is unfolded to repair the rear wheel. When replacing, the top and side covers are moved up to fully expose the rear wheel, allowing for flexible disassembly and assembly. This addresses the problem that most electric vehicle rear wheel protection structures often have mudguards or protective covers fixed directly to the outside of the rear wheel, resulting in limited protection. Furthermore, when the rear wheel is being repaired or replaced, the protective structure can obstruct vision and operation, requiring the removal of the protective structure before any work can be carried out. This enhances the practical value of the device. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 4This utility model provides an embodiment of an anti-accidental contact device for the rear wheel of an electric vehicle, comprising a rear wheel body 1, a connecting shaft 2, a frame body 3, a protective top cover 4, a lifting assembly, a protective side cover 5, an opening and closing assembly, and a through groove 6. The connecting shaft 2 is located in the middle of the rear wheel body 1, and the rear wheel body 1 is rotatably connected to the connecting shaft 2. Both ends of the connecting shaft 2 are fixedly connected to the inner bottom of the frame body 3. A lifting assembly is located on the inner side of the frame body 3, and a protective top cover 4 is located on one side of the lifting assembly. The protective top cover 4 is positioned on the rear wheel body. Above the body 1, the protective top cover 4 is fitted to the top of the rear wheel body 1. The protective top cover 4 protects the top of the rear wheel body 1 to prevent mud and sand from splashing. Two sets of protective side covers 5 are symmetrically arranged on the outer ends of the protective top cover 4. The protective side covers 5 protect both sides of the rear wheel body 1, thereby providing comprehensive physical isolation and protection for the rear wheel body 1 to prevent accidental contact. The top of the protective side cover 5 is provided with an opening and closing component. A through groove 6 is opened in the middle of the protective side cover 5. The bottom of the frame body 3 passes through the protective side cover 5 through the through groove 6.

[0023] Please see Figure 2 In this embodiment, the lifting assembly includes a lifting mechanism 401, a drive motor 402, and a connecting block 403. The lifting mechanism 401 is located on the inner side of the vehicle frame body 3. The lifting mechanism 401 can be any one of a ball screw, electric push rod, electric cylinder, linear motor, pneumatic cylinder, or hydraulic cylinder. The drive motor 402 is located at the bottom end of the vehicle frame body 3. The drive motor 402 is electrically connected to the electric vehicle control mechanism, and the output end of the drive motor 402 is electrically connected to the drive mechanism of the lifting mechanism 401. A connecting block 403 is provided on the outer side of 1. The connecting block 403 moves linearly through the lifting mechanism 401. The bottom outer side of the protective top cover 4 is fixedly connected to the connecting block 403. The drive motor 402 is controlled by the control mechanism to run. The drive motor 402 drives the lifting mechanism 401 to operate. The lifting mechanism 401 drives the connecting block 403 to move up and down. The connecting block 403 is used to connect and fix the protective top cover 4, thereby flexibly adjusting the placement height of the protective top cover 4 and the protective side cover 5, and facilitating the replacement of the rear wheel body 1.

[0024] Please see Figure 3 and Figure 4In this embodiment, the opening and closing assembly includes a fixing plate 501, a rotating shaft 502, and a damping pad 503. Two sets of fixing plates 501 are symmetrically arranged at both ends of the outer side of the protective top cover 4. The fixing plates 501 are arranged in pairs and are located on both sides of the frame body 3. The two sets of fixing plates 501 are rotatably connected by a rotating shaft 502. The top of the protective side cover 5 is located on the outside of the rotating shaft 502. The two ends of the rotating shaft 502 are provided with damping pads 503. The rotating shaft 502 is rotatably connected to the fixing plate 501. The damping pads 503 increase the rotational resistance of the rotating shaft 502, ensuring that the protective side cover 5 can remain in the unfolded state. The rotating shaft 502 can be rotated to flexibly open and close the protective side cover 5, thereby facilitating the maintenance of the rear wheel body 1. When there is a passenger in the rear seat, even if the protective side cover 5 is in the unfolded state, the passenger's feet will naturally put down and the protective side cover 5 will close, which can effectively avoid the safety accident of accidental contact when the electric vehicle is in motion.

[0025] When driving, the frame body 3 is connected to the fixed connecting shaft 2, and the rear wheel body 1 rotates around the connecting shaft 2 to ensure the normal driving of the electric vehicle. The top of the rear wheel body 1 is protected by the protective top cover 4 to prevent mud and sand from splashing. The protective side cover 5 passes through the frame body 3 through the through groove 6, so that the protective side cover 5 protects both sides of the rear wheel body 1, thereby providing comprehensive physical isolation and protection for the rear wheel body 1 to prevent accidental contact.

[0026] When inspecting the rear wheel body 1, rotate the shaft 502 around the fixed plate 501 to unfold the protective side cover 5. Use the damping pad 503 to increase the rotation resistance of the shaft 502, so that the protective side cover 5 is kept unfolded, and perform maintenance on the rear wheel body 1.

[0027] When replacing the rear wheel body 1, the drive motor 402 is controlled by the control mechanism to run, and the lifting mechanism 401 is driven by the drive motor 402 to run. The lifting mechanism 401 drives the connecting block 403 to move upward. The moving connecting block 403 drives the protective top cover 4 and the protective side cover 5 to move upward simultaneously, so that the rear wheel body 1 is completely exposed. Then the rear wheel body 1 can be flexibly disassembled and reassembled.

[0028] Through the above steps, the rear wheel body 1 is connected to the frame body 3 by rotating the connecting shaft 2. The top of the rear wheel body 1 is protected by the protective top cover 4 to prevent mud and sand from splashing. The sides of the rear wheel body 1 are protected by the protective side cover 5. The protective side cover 5 passes through the frame body 3 through the through groove 6, thus providing comprehensive physical isolation and protection for the rear wheel body 1 to prevent accidental contact. The height of the protective top cover 4 and the protective side cover 5 can be flexibly adjusted by the lifting component, and the protective side cover 5 can be flexibly unfolded by the opening and closing component, thus ensuring that the rear wheel is fully protected, preventing accidental contact by personnel, improving the safety of electric vehicle use, and flexibly adjusting the position of the protective structure according to actual operating needs.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
