Description

Technical Field

[0001] This utility model relates to the field of electric vehicle gearbox technology, and in particular to a collision-resistant electric vehicle gearbox housing. Background Technology

[0002] The gearbox is an important component of an electric tricycle. As the core of power transmission between the drive motor and the rear axle, it can convert the high-speed, low-torque power output of the drive motor into low-speed, high-torque power that is adapted to the vehicle's driving needs, ensuring that the electric vehicle can obtain smooth and efficient power output under different working conditions such as starting, acceleration, climbing, and high-speed cruising.

[0003] Existing electric vehicle gearbox housings rely solely on their own shell strength to withstand collisions during use. While this provides good impact protection, collisions are still common. This can lead to the peeling of the anti-rust coating on the housing surface, reducing corrosion resistance, and may also cause misalignment of the internal gear shafts, affecting transmission performance. Therefore, we have developed a collision-resistant electric vehicle gearbox housing. Utility Model Content

[0004] This utility model provides a collision-proof electric vehicle gearbox housing that can form a protective shield for the gearbox body, effectively preventing the anti-rust coating on its surface from peeling off, and also reducing the transmission of vibration to the inside of the gearbox body, further ensuring the stable transmission effect of the gearbox body.

[0005] The purpose and effect of this utility model for a collision-resistant electric vehicle gearbox housing are achieved by the following specific technical means: A collision-resistant electric vehicle gearbox housing includes a gearbox body and a rear axle housing disposed on the front and rear sides of the gearbox body, and further includes: The protective assembly, located outside the gearbox body, includes a set of symmetrical protective shells slidably connected to the rear axle housing and located outside the gearbox body, and a stabilizing structure disposed on the protective shells for connecting them to the rear axle housing. Energy-absorbing components, located outside the protective shell, are used to absorb and buffer collision energy.

[0006] Preferably, the stabilizing structure includes bolts threaded to one side of each protective housing, a sector plate threaded to the outer surface of each bolt, a set of support plates fixedly connected to the outer surface of each sector plate, and one end of each support plate connected to the outer surface of the rear axle housing.

[0007] Preferably, each of the sector plates has a set of stabilizing holes on one side, and a stabilizing post is inserted into the interior of each stabilizing hole. One end of each stabilizing post is connected to the inner wall of the protective shell.

[0008] Preferably, a set of guide plates is slidably connected to the inner side of each of the protective shells, and the outer surface of each guide plate is connected to the outer surface of the rear axle shell.

[0009] Preferably, in a set of protective shells, the inner wall of one of the protective shells is fixedly connected with a ring of inserted rods, each of the inserted rods is fitted with a connecting cylinder, and the outer surface of each connecting cylinder is connected to the inner wall of the other protective shell.

[0010] Preferably, each of the protective shells is made of stainless steel.

[0011] Preferably, the energy-absorbing component includes multiple sets of springs fixedly connected to the outer surface of each protective shell, and the other end of each set of springs is fixedly connected to an energy-absorbing plate.

[0012] Preferably, an energy-absorbing pad is fixedly connected to the outer surface of each energy-absorbing plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] First Embodiment As attached Figure 1 To be continued Figure 5 As shown: A collision avoidance electric vehicle gearbox housing includes a gearbox body 1 and a rear axle housing 2 disposed on the front and rear sides of the gearbox body 1. It also includes a protective component 3 disposed on the outside of the gearbox body 1, including a set of symmetrical protective shells 301 slidably connected to the rear axle housing 2 and located on the outside of the gearbox body 1. Each protective shell 301 is made of stainless steel. The protective shells 301 can shield and protect the gearbox body 1 from the outside, and the use of stainless steel can prevent rusting.

[0026] A stabilizing structure is installed on the protective housing 301 to connect it to the rear axle housing 2. The stabilizing structure includes bolts 302 threaded to one side of each protective housing 301. Each bolt 302 has a sector plate 303 threaded to its outer surface. Each sector plate 303 has a set of support plates 304 fixedly connected to its outer surface. One end of each support plate 304 is connected to the outer surface of the rear axle housing 2. When the protective housing 301 is moved to the outside of the gearbox body 1, the bolts 302 are then tightened so that they pass through the screw holes on the protective housing 301 and are tightly connected to the sector plate 303. This stabilizes the protective housing 301 on the rear axle housing 2, forming a full-coverage shielding protection for the gearbox body 1. This effectively prevents the gearbox body 1 from being hit, avoids the anti-rust coating on its surface from falling off due to impact, and also reduces the transmission of vibration to the inside of the gearbox body 1, preventing deviation in the coaxiality of the gear shaft, and further ensuring the stable transmission effect of the gearbox body 1.

[0027] Each sector plate 303 has a set of stabilizing holes 305 on one side, and a stabilizing post 306 is inserted into the interior of each stabilizing hole 305. One end of each stabilizing post 306 is connected to the inner wall of the protective shell 301. After the protective shell 301 is moved to the outside of the gearbox body 1, the stabilizing post 306 will be inserted into the stabilizing hole 305 simultaneously, allowing the sector plate 303 to connect with the protective shell 301, further enhancing the stability of the protective shell 301 and preventing the protective shell 301 from shifting. Each protective shell 301 has a set of guide plates 307 slidably connected to its inner side, and the outer surface of each guide plate 307 is connected to the rear axle housing. The outer surfaces of the two protective shells are connected. The guide plate 307 can guide the movement of the protective shell 301, avoiding tilting or misalignment of the protective shell 301 due to manual adjustment, and facilitating the fixing of the protective shell 301. One of the protective shells 301 has a ring of inserted rods 308 fixedly connected to its inner wall. Each inserted rod 308 is fitted with a connecting cylinder 309. The outer surface of each connecting cylinder 309 is connected to the inner wall of another protective shell 301. When the two protective shells 301 are spliced ​​together, the inserted rods 308 will connect to the inside of the connecting cylinder 309 simultaneously, thereby enhancing the firmness of the spliced ​​protective shells 301.

[0028] Second Embodiment As attached Figure 1 Appendix Figure 2 With appendix Figure 6As shown: Energy-absorbing component 4, disposed outside the protective shell 301, is used to absorb and buffer collision energy. The energy-absorbing component 4 includes multiple sets of springs 401 fixedly connected to the outer surface of each protective shell 301. The other end of each set of springs 401 is fixedly connected to an energy-absorbing plate 402. When a collision occurs during vehicle operation, the energy-absorbing plate 402 outside the protective shell 301 will first contact the colliding object. By compressing the springs 401, it absorbs the collision force, greatly reducing the damage to the protective shell 301. Each set of springs 401 is arranged in a ring around the axis of the protective shell 301. The even distribution of the springs 401 can better disperse the collision force borne by the energy-absorbing plate 402. An energy-absorbing pad 403 is fixedly connected to the outer surface of each energy-absorbing plate 402. The energy-absorbing pad 403 can disperse and absorb the collision force borne by the energy-absorbing plate 402, further improving the protective effect.

[0029] Each energy-absorbing plate 402 has a positioning plate 404 fixedly connected to one side, and a positioning frame 405 is slidably connected to the outer surface of each positioning plate 404. One side of each positioning frame 405 is connected to the outer surface of the protective shell 301. The connection between the positioning plate 404 and the positioning frame 405 can stabilize the energy-absorbing plate 402 and prevent it from shifting.

[0030] Working principle: When in use, push the protective shell 301 along the rear axle housing 2 to bring them closer together, so that they can slide precisely to the outside of the gearbox body 1. At the same time, the insert rod 308 inside the protective shell 301 will automatically insert into the connecting cylinder 309 of the adjacent protective shell 301 to form a preliminary splicing and fixation. Then, tighten the bolt 302 so that it passes through the screw hole on the protective shell 301 and the sector plate 303 to connect tightly, thus fixing the protective shell 301 stably on the rear axle housing 2, forming a full-coverage shield protection for the gearbox body 1, effectively preventing the gearbox body 1 from being involved in a collision.

[0031] When a collision occurs while the vehicle is in motion, the energy-absorbing plate 402 on the outside of the protective shell 301 will first come into contact with the object colliding with it. By compressing the spring 401, it absorbs the impact force, greatly reducing the damage to the protective shell 301. This not only prevents the gearbox body 1 from directly bearing the impact and avoids the anti-rust coating on its surface from falling off due to the impact, but also reduces the transmission of vibration to the inside of the gearbox body 1, preventing the coaxiality of the gear shaft from deviating, and further ensuring the stable transmission effect of the gearbox body 1.
