Description

Technical Field

[0001] This utility model relates to the field of electric vehicle rear axle technology, and in particular to an electric vehicle anti-collision rear axle. Background Technology

[0002] The rear axle of an electric vehicle is a core load-bearing component that connects the rear wheel of the electric vehicle, supports the weight of the vehicle body, and transmits driving force. The power of the motor inside is transmitted to the half shaft through the reducer and differential, and then drives the wheel hub to rotate the rear wheel, which can provide the electric vehicle with forward or backward power. At the same time, through the connection between the rear axle housing and the vehicle body suspension system, it maintains the vehicle's driving stability and bears the reverse torque generated when the vehicle brakes, ensuring braking safety and reliability.

[0003] Currently, to prevent collisions, electric vehicle rear axles are equipped with external anti-collision measures, which are directly mounted on the rear axle using rigid connectors. These anti-collision measures lack effective energy buffer structures, causing most of the impact force to be directly transmitted to the rear axle through the rigid connection during a collision. Under the impact force, the axle is prone to bending and deformation, thus affecting the normal use of the electric vehicle. To address this, we provide an anti-collision rear axle for electric vehicles. Utility Model Content

[0004] This utility model provides an anti-collision rear axle for electric vehicles. The arc-shaped anti-collision shell is stabilized under the rear axle body, which not only protects the rear axle body, but also prevents the impact force from being transmitted to the rear axle body when it is hit, thereby ensuring the normal use of the rear axle body. It can also buffer the impact force on the arc-shaped anti-collision shell, effectively preventing it from deforming and breaking, and further ensuring its continuous protection of the rear axle body.

[0005] The purpose and effect of this utility model's anti-collision rear axle for electric vehicles are achieved by the following specific technical means: An anti-collision rear axle for electric vehicles includes a rear axle body, and further includes:

[0006] An arc-shaped anti-collision shell is located below the rear axle body and its shape is adapted to the rear axle body;

[0028] 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.

[0029] First Embodiment

[0030] As attached Figure 1 To be continued Figure 5 As shown: An electric vehicle anti-collision rear axle includes a rear axle body 1 and an arc-shaped anti-collision shell 2, which is disposed below the rear axle body 1 and whose shape is adapted to the rear axle body 1. The arc-shaped anti-collision shell 2 is made of aluminum alloy and can withstand a large collision force. A first anti-collision pad 4 and a second anti-collision pad 5 are fixedly connected to the upper surface of the arc-shaped anti-collision shell 2. When the arc-shaped anti-collision shell 2 moves too high during a collision, the first anti-collision pad 4 and the second anti-collision pad 5 can prevent rigid contact between the arc-shaped anti-collision shell 2 and the rear axle body 1, thereby forming further protection for the rear axle body 1.

[0031] Second Embodiment

[0032] The support buffer assembly 3 is located above the rear axle body 1 and includes a set of U-shaped hanging plates 301 located above the rear axle body 1 and a sliding frame 302 slidably connected to each U-shaped hanging plate 301 and connected at its bottom end to the arc-shaped anti-collision shell 2. Each U-shaped hanging plate 301 has a fixed plate 311 fixedly connected to its top end. Each fixed plate 311 has a set of mounting holes on its upper surface. The fixed plate 311 can be used to stably install the U-shaped hanging plate 301 at the bottom of the frame, thereby stabilizing the arc-shaped anti-collision shell 2 below the rear axle body 1.

[0033] Each sliding frame 302 has a second spring 308 fixedly connected to its inner side. The second spring 308 can enhance the tension between the sliding frames 302 and increase the strength of the sliding frames 302. Each sliding frame 302 has a limit frame 309 fixedly connected to its outer surface. Each limit frame 309 is located above the bottom end of the U-shaped hanging plate 301. The limit frame 309 can restrict the downward movement of the sliding frame 302, thereby ensuring that the arc-shaped anti-collision shell 2 is stable under the rear axle body 1. Each sliding frame 302 has a set of inclined plates 312 fixedly connected to one side. The other end of each inclined plate 312 is connected to the outer surface of the arc-shaped anti-collision shell 2. The inclined plates 312 can enhance the connection strength between the arc-shaped anti-collision shell 2 and the sliding frame 302.

[0034] A buffer structure is installed between the U-shaped hanging plate 301 and the sliding frame 302 to absorb and buffer the impact force received by the arc-shaped anti-collision shell 2. The buffer structure includes a set of springs 303 fixedly connected to the bottom surface of the top of each sliding frame 302. The bottom end of each spring 303 is connected to the upper surface of the bottom end of the U-shaped hanging plate 301. When a collision occurs, the arc-shaped anti-collision shell 2 will transmit the impact force to the sliding frame 302. The sliding frame 302 will pull the spring 303 upward, and the spring 303 will stretch to absorb part of the impact force.

[0035] The buffer structure also includes a set of connecting plates 304 hinged to the top and bottom surfaces of each sliding frame 302. Each connecting plate 304 has a pressing block 305 hinged to its bottom end. Each pressing block 305 has a first spring 306 on one side, and the bottom ends of both sides of the first spring 306 are connected to the upper surface of the U-shaped hanging plate 301. When the sliding frame 302 moves upward, it simultaneously lifts the connecting plate 304, which pulls the pressing block 305. The pressing block 305 then presses against the first spring 306, converting some of the impact force into the force exerted by the pressing block 305 and the first spring. The friction between the plates 306 protects the arc-shaped anti-collision shell 2, effectively preventing deformation and damage, and further ensuring its continuous protection of the rear axle body 1. Each set of extrusion blocks 305 is slidably connected to a guide plate 307. The left and right ends of each guide plate 307 are connected to the upper surface of the U-shaped hanging plate 301, and the outer surface of the guide plate 307 is arc-shaped. The guide plate 307 can guide the movement of the extrusion block 305, thereby ensuring that the extrusion block 305 and the first spring plate 306 rub against each other to consume the collision force.

[0036] Each sliding frame 302 has an energy-absorbing pad 310 fixedly connected to its upper surface. When the sliding frame 302 is subjected to excessive impact force and moves upward, the energy-absorbing pad 310 will be compressed and absorb part of the impact force, thereby preventing the sliding frame 302 from being damaged by impact.

[0037] Working principle: In use, the arc-shaped anti-collision shell 2 is placed below the rear axle body 1, and then the U-shaped hanging plate 301 is fixed to the bottom of the frame using the fixing plate 311, thereby stabilizing the arc-shaped anti-collision shell 2 below the rear axle body 1 for protection. When a collision occurs, the arc-shaped anti-collision shell 2 can prevent the collision force from being transmitted to the rear axle body 1, thus preventing the rear axle body 1 from bending under stress. At the same time, the collision force will be transmitted to the sliding frame 302, which will pull the spring 303 upward. The spring 303 will stretch and absorb part of the collision force. When the sliding frame 302 moves upward, it will simultaneously lift the connecting plate 304 upward. The connecting plate 304 will pull the compression block 305, which will compress the first spring 306, converting part of the collision force into friction between the compression block 305 and the first spring 306, thus protecting the arc-shaped anti-collision shell 2 and effectively preventing it from deforming and breaking, further ensuring its continuous protection of the rear axle body 1.
