[0001] This application relates to the field of electric vehicle drive axle technology, specifically to an auxiliary mounting bracket for electric vehicle drive axles. Background Technology

[0002] The drive axle of an electric vehicle is a core component of the power system of a new energy vehicle. It integrates the motor, electronic control unit, reducer and drive axle into one unit to achieve efficient power output and integrated braking control of the vehicle.

[0003] Currently, the load-bearing platform and support points of existing support devices are mostly integrated and fixed designs, which makes it difficult to adjust according to the size of different drive axle models and the spacing of mounting holes. This requires separate brackets for different vehicle models, increasing production costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides an auxiliary mounting bracket for the drive axle of electric vehicles, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: an auxiliary mounting bracket for an electric vehicle drive axle, comprising a base, with adjustment mechanisms at both ends of the base and a mounting mechanism on top of the base. The adjustment mechanism includes a limiting hole and a limiting rod, the limiting hole being opened on top of the base and the limiting rod being slidably connected to the inner wall surface of the limiting hole.

[0008] By adopting the above technical solution, the lateral spacing of the mounting mechanism can be flexibly adjusted through the adjustment mechanism, making it compatible with various models of drive axles, improving the versatility of the bracket, and reducing production costs. The mounting mechanism also improves installation efficiency and quality, and provides buffer protection and stable fixation for the drive axle.

[0009] Preferably, a support pad is fixedly installed on the lower surface of the base, and the lower surface of the support pad is provided with anti-slip texture, and a slide rail is fixedly installed on the upper surface of the base.

[0010] By adopting the above technical solution, the anti-slip texture of the support pad can increase the friction between the base and the ground, preventing the bracket from shifting during installation and improving overall stability; the slide rail provides guidance for the movement of the installation mechanism, ensuring smooth position adjustment.

[0011] Preferably, a slider is slidably connected to the inner wall surface of the slide rail, the limiting hole is opened on one side of the slide rail and passes through the slide rail and the slider on one side, and a connecting pipe is slidably connected to the inner wall surface of the slider.

[0012] By adopting the above technical solution, the slider can slide along the slide rail, driving the installation mechanism to adjust the lateral spacing. The limiting hole and the limiting rod can fix the position of the slider. The connecting tube provides guidance for the movement of the limiting rod to prevent it from deviating.

[0013] Preferably, a pull plate is fixedly installed on one side of the connecting pipe, the limiting rod is fixedly installed on one side of the pull plate, a No. 1 spring is fixedly installed on one side of the pull plate, and the other end of the No. 1 spring is fixedly connected to one side of the inner wall of the slider.

[0014] By adopting the above technical solution, the limit rod can be disengaged from the limit hole by pulling the pull plate, which makes it easier to adjust the position of the slider.

[0015] Preferably, a lower connecting plate is fixedly installed on the upper surface of the slider, a groove is formed on the upper surface of the base, a support block is slidably connected to the inner wall surface of the groove, and the support block is fixedly connected to the lower surface of the lower connecting plate.

[0016] By adopting the above technical solution, the lower connecting plate can be moved synchronously with the slider by the cooperation of the support block and the slide groove, while enhancing the support stability of the lower connecting plate.

[0017] Preferably, a damper is fixedly installed on the upper surface of the lower connecting plate, an upper connecting plate is fixedly installed on the other end of the damper, and a second spring is fixedly installed on the upper surface of the lower connecting plate.

[0018] By adopting the above technical solution, a buffer structure can be formed by the damper and the second spring, which can absorb the vibration generated by the drive axle during installation, avoid component damage caused by rigid collision, and provide flexible support when adjusting the position of the drive axle, thereby improving operational safety.

[0019] Preferably, the other end of the second spring is fixedly connected to the lower surface of the upper connecting plate, and a rubber pad is fixedly installed on the upper surface of the upper connecting plate. The rubber pad has an installation hole on its upper surface, and the installation hole penetrates the rubber pad and the upper surface of the upper connecting plate.

[0020] By adopting the above technical solution, the rubber pad can directly contact the drive axle, avoiding scratches on the drive axle surface, while increasing friction to prevent the drive axle from shifting; the mounting holes can be used to fix the drive axle to the upper connecting plate with bolts, ensuring the stability of the drive axle position during installation and facilitating subsequent docking with the vehicle chassis.

[0021] (III) Beneficial Effects

[0022] This application provides an auxiliary mounting bracket for the drive axle of an electric vehicle. It has the following advantages:

[0023] 1. This electric vehicle drive axle auxiliary mounting bracket, by incorporating an adjustment mechanism, solves the problem that previous support devices, with their integrated fixed design of the bearing platform and support points, were difficult to adjust according to the size and mounting hole spacing of different drive axle models. This required separate brackets for different vehicle models, increasing production costs. The bracket achieves the beneficial effects of flexibly adjusting the lateral spacing of the mounting mechanism, adapting to multiple drive axle models, improving bracket versatility, and reducing production costs.

[0024] 2. This auxiliary mounting bracket for the drive axle of electric vehicles solves the problems of easy scratching of the drive axle and vibration affecting accuracy during the previous installation process by setting up an installation mechanism. The damper and the No. 2 spring absorb vibration, the rubber pad avoids surface scratches, and the mounting holes ensure accurate positioning of the drive axle. It achieves the beneficial effects of improving installation efficiency and quality, and providing buffer protection and stable fixation for the drive axle. Attached Figure Description

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0033] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Reference Figure 1 and Figure 2This application provides an auxiliary mounting bracket for an electric vehicle drive axle, including a base 1, with adjustment mechanisms 2 at both ends of the base 1 and a mounting mechanism 3 on top of the base 1. The adjustment mechanism 2 includes a limiting hole 204 and a limiting rod 208. The limiting hole 204 is located above the base 1, and the limiting rod 208 is slidably connected to the inner wall surface of the limiting hole 204. By adjusting the mechanism 2, the base 1 can be placed in the installation area, ensuring that the support pad 201 on the lower surface of the base 1 is completely in contact with the ground. The anti-slip texture on the lower surface of the support pad 201 effectively increases the friction with the ground, preventing displacement or shaking of the bracket during subsequent installation operations, providing stable foundation support for the entire installation process. Next, according to the size of the drive axle to be installed, the operator pulls the pull plate 207 outwards by hand. Under force, the pull plate 207 drives the limiting rod 208 fixed on one side to slide along the inner wall of the connecting pipe 205, causing the limiting rod 208 to gradually disengage from the limiting hole 204 on the slide rail 202 and the slider 203. When the first spring 206 is compressed and stores elastic potential energy due to the movement of the pull plate 207, it pushes the slider 203 to slide along the slide rail 202 on the upper surface of the base 1. As the slider 203 moves, it will drive the lower connecting plate 301, which is fixedly connected to its upper surface, to move synchronously, thereby adjusting the distance between the two mounting mechanisms 3. After the distance is adjusted to match the drive axle, the pull plate 207 is released, the first spring 206 releases its elastic potential energy and pushes the pull plate 207 to reset. The pull plate 207 drives the limit rod 208 to re-insert into the corresponding limit hole 204, completing the fixation of the slider 203 and ensuring that the distance between the mounting mechanisms 3 remains stable. The drive axle can be hoisted onto the upper connecting plate 305 via the installation mechanism 3, aligning the drive axle with the mounting hole 308 and securing it with bolts. During the entire installation process, the damper 304 between the lower connecting plate 301 and the upper connecting plate 305 can effectively absorb the vibration generated during hoisting and fixing, preventing the vibration from being transmitted to the drive axle and causing damage to its internal components. At the same time, the second spring 306 sleeved on the outside of the damper 304 can work with the damper 304 to enhance the buffering effect. Meanwhile, the rubber pad 307 on the upper surface of the upper connecting plate 305 can directly contact the surface of the drive axle, preventing the drive axle from rigidly colliding with the metal upper connecting plate 305 and avoiding scratches or dents on the surface of the drive axle.

[0035] Reference Figure 2 , Figure 3 and Figure 4 In one aspect of this embodiment, a support pad 201 is fixedly installed on the lower surface of the base 1, and the lower surface of the support pad 201 is provided with anti-slip texture. A slide rail 202 is fixedly installed on the upper surface of the base 1.

[0036] A slider 203 is slidably connected to the inner wall surface of the slide rail 202. A limiting hole 204 is opened on one side of the slide rail 202 and passes through the slide rail 202 and the slider 203. A connecting pipe 205 is slidably connected to the inner wall surface of the slider 203.

[0037] A pull plate 207 is fixedly installed on one side of the connecting pipe 205, and a limiting rod 208 is fixedly installed on one side of the pull plate 207. A first spring 206 is fixedly installed on one side of the pull plate 207, and the other end of the first spring 206 is fixedly connected to one side of the inner wall of the slider 203. By placing the base 1 in the installation area, it is ensured that the support pad 201 on the lower surface of the base 1 is completely in contact with the ground. The anti-slip texture on the lower surface of the support pad 201 can effectively increase the friction with the ground, preventing the bracket from shifting or shaking during subsequent installation operations, and providing a stable foundation support for the entire installation process. Then, according to the size of the drive axle to be installed, the operator pulls the pull plate 207 outward by hand. After being subjected to force, the pull plate 207 will drive the limiting rod 208 fixed on one side of it along the connecting pipe 205. The inner wall slides, causing the limiting rod 208 to gradually disengage from the limiting hole 204 on the slide rail 202 and the slider 203. At this time, the first spring 206 is compressed and stores elastic potential energy due to the movement of the pull plate 207. Then, it pushes the slider 203 to slide along the slide rail 202 on the upper surface of the base 1. As the slider 203 moves, it will drive the lower connecting plate 301, which is fixedly connected to its upper surface, to move synchronously, thereby adjusting the distance between the two mounting mechanisms 3. After the distance is adjusted to match the drive axle, the pull plate 207 is released, the first spring 206 releases its elastic potential energy and pushes the pull plate 207 to reset. The pull plate 207 drives the limiting rod 208 to re-insert into the corresponding limiting hole 204, completing the fixation of the slider 203 and ensuring that the distance between the mounting mechanisms 3 remains stable.

[0038] Reference Figure 3 and Figure 5 In one aspect of this embodiment, a lower connecting plate 301 is fixedly installed on the upper surface of the slider 203, and a groove 302 is provided on the upper surface of the base 1. A support block 303 is slidably connected to the inner wall surface of the groove 302, and the support block 303 is fixedly connected to the lower surface of the lower connecting plate 301.

[0039] A damper 304 is fixedly installed on the upper surface of the lower connecting plate 301, and an upper connecting plate 305 is fixedly installed on the other end of the damper 304. A second spring 306 is fixedly installed on the upper surface of the lower connecting plate 301.

[0040] The other end of the second spring 306 is fixedly connected to the lower surface of the upper connecting plate 305. A rubber pad 307 is fixedly installed on the upper surface of the upper connecting plate 305. A mounting hole 308 is opened on the upper surface of the rubber pad 307, which passes through the rubber pad 307 and the upper surface of the upper connecting plate 305. By hoisting the drive axle to the upper connecting plate 305, aligning the drive axle with the mounting hole 308, and fixing it with bolts, the damper 304 between the lower connecting plate 301 and the upper connecting plate 305 can effectively absorb the vibration generated during hoisting and fixing, and prevent the vibration from being transmitted to the drive axle and causing damage to its internal components. At the same time, the second spring 306 sleeved on the outside of the damper 304 can work with the damper 304 to enhance the buffering effect, while the rubber pad 307 on the upper surface of the upper connecting plate 305 can directly contact the surface of the drive axle, preventing the drive axle from having a rigid collision with the metal upper connecting plate 305 and avoiding scratches or dents on the surface of the drive axle.

[0041] All electrical devices in this plan are powered by an external power source.

[0042] Working Principle: When using this device, first place the base 1 in the installation area, ensuring that the support pad 201 on the lower surface of the base 1 is completely in contact with the ground. The anti-slip texture on the lower surface of the support pad 201 effectively increases the friction with the ground, preventing the bracket from shifting or shaking during subsequent installation operations, and providing stable foundation support for the entire installation process. Next, according to the size of the drive axle to be installed, the operator pulls the pull plate 207 outward by hand. After being subjected to force, the pull plate 207 will drive the limiting rod 208 fixed on one side to slide along the inner wall of the connecting pipe 205, so that the limiting rod 208 gradually disengages from the limiting hole 204 on the slide rail 202 and the slider 203. At this time, the first spring 206 is compressed and stores elastic potential energy due to the movement of the pull plate 207. Then, it pushes the slider 203 to slide along the slide rail 202 on the upper surface of the base 1. As the slider 203 moves, it will drive the lower connecting plate 301, which is fixedly connected to its upper surface, to move synchronously, thereby adjusting the distance between the two mounting mechanisms 3. After the distance is adjusted to match the drive axle, the pull plate 207 is released, the first spring 206 releases its elastic potential energy and pushes the pull plate 207 to reset. The pull plate 207 drives the limit rod 208 to re-insert into the corresponding limit hole 204, completing the position fixation of the slider 203 and ensuring that the distance between the mounting mechanisms 3 remains stable. The drive axle is then hoisted onto the upper connecting plate 305, aligning it with the mounting hole 308, and secured with bolts. Throughout the installation process, the damper 304 between the lower connecting plate 301 and the upper connecting plate 305 effectively absorbs vibrations generated during hoisting and securing, preventing vibrations from being transmitted to the drive axle and damaging its internal components. Meanwhile, the second spring 306, fitted on the outside of the damper 304, works in conjunction with the damper 304 to enhance the buffering effect. The rubber pad 307 on the upper surface of the upper connecting plate 305 can directly contact the surface of the drive axle, preventing a rigid collision between the drive axle and the metal upper connecting plate 305, thus avoiding scratches or dents on the surface of the drive axle.
