[0002] Generally, the motors used in electric vehicles are installed in a hub-shaped housing. However, since the motor hub serves as the driving wheel, collisions often occur. However, the traditional motor housing lacks a shock-absorbing structure, which can easily cause surface damage to the motor housing in the event of a collision, and in severe cases, can easily cause damage to the internal motor.

[0003] Patent number: CN219067989U, discloses a motor housing with shock-absorbing performance, which effectively prevents damage caused by collision of the motor cover corners, thereby effectively solving the problem that traditional motor housings lack shock-absorbing structures and are easily damaged when collision occurs.

[0004] However, during the implementation of this solution, since the device only relies on shock-absorbing pads to cushion and reduce vibration, the movement distance of the motor cover is short, which causes the motor cover to be damaged when it is hit, and the shock-absorbing effect is insufficient. Therefore, a motor housing with shock-absorbing performance is proposed. Utility Model Content

[0024] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] See also Figure 1-4 The utility model provides a technical solution: a motor casing with shock absorption performance, including a motor housing 1, an end cover 2 is provided inside the motor housing 1, the end cover 2 is in the shape of a non-connected cylinder, the end cover 2 is connected to the motor housing 1 by bolts, and a ring groove 17 is provided on the surface of the end cover 2 away from the motor housing 1, and a moving ring 7 with a tapered inner wall is provided on the surface of the end cover 2 away from the motor housing 1, and a shock-absorbing pad 3 is fixedly connected to the surface of the moving ring 7. Then, through the setting of the shock-absorbing pad 3, when a collision occurs at the edge of the moving ring 7, it will hit the shock-absorbing pad 3, and the shock-absorbing pad 3 will play a certain shock-absorbing role and is not easy to be damaged, effectively preventing the damage caused by collision of the corners of the moving ring 7.

[0026] Furthermore, an end of the movable ring 7 close to the end cover 2 is fixedly connected to an extension plate 8, the surface of the extension plate 8 is slidably connected to the inner wall of the annular groove 17, the inner wall of the extension plate 8 is fixedly connected to a bearing 9, the inner wall of the bearing 9 is fixedly connected to the inner wall of the annular groove 17, and thus, through the setting of the bearing 9, the friction between the movable ring 7 and the end cover 2 is reduced, so that when the movable ring 7 is subjected to a collision, since the movable ring 7 is annular, it can be driven by the collision force to make the movable ring 7 rotate to a certain extent, thereby further unloading the collision force, further buffering and shock-absorbing the collision force, avoiding damage to the device, and improving the use effect of the device.

[0027] The inner wall of the end cover 2 away from the motor housing 1 is fixedly connected with a fixed sleeve 4, and the surface of the fixed sleeve 4 is provided with slide grooves 5 arranged at equal distances around the circumference, and the slide grooves 5 are composed of vertical grooves and inclined arc grooves. The inner wall of the end cover 2 is provided with force blocks 6 arranged at equal distances around the circumference, and the surface of the force blocks 6 slides with the inner wall of the end cover 2. The surface of the force blocks 6 is fixedly connected with a slide rod 10, and the surface of the slide rod 10 slides with the inner wall of the slide groove 5.

[0028] Furthermore, a movable groove 11 is provided on the surface of the force-bearing block 6, and a slide plate 12 is slidably connected to the inner wall of the movable groove 11, and a fixed rod 14 is fixedly connected to the surface of the slide plate 12, and a movable sleeve 16 is slidably connected to the surface of the fixed rod 14, and a spring 15 is fixedly connected between the fixed sleeve 4 and the movable sleeve 16. Then, through the setting of the spring 15, the external impact force on the force-bearing block 6 can be converted into the elastic force of the spring 15, thereby buffering and shock-absorbing the impact force on the force-bearing block 6, thereby avoiding damage to the motor housing 1.

[0029] A rubber pad 18 is fixedly connected to the inner wall of the end cover 2 away from the motor housing 1. The surface of the movable sleeve 16 is in contact with the surface of the rubber pad 18. Through the setting of the rubber pad 18, after the force block 6 is moved away, it can contact the impact object and utilize the elastic force of the force block 6 to buffer the impact force again, thereby avoiding the impact force from damaging the end cover 2, further improving the protection effect of the device, and improving the practicality of the device.

[0030] Furthermore, a slider 13 is fixedly connected to the surface of the movable groove 11, and the surface of the slider 13 is slidably connected to the inside of the force block 6. A spring 15 is also fixedly connected to the surface of the slider 13, and the end of the spring 15 away from the slider 13 is fixedly connected to the inside of the force block 6, and the spring 15 on the slider 13 is arranged in an arc shape.

[0031] Specifically, when the inner wall of the mobile ring 7 is hit, the impact force is directed to the force block 6 under the inclined surface of the inner wall of the mobile ring 7, so that the force block 6 is subjected to force, and then the force block 6 is driven to move, and the slide bar 10 is driven to slide in the slide groove 5, so that the fixed rod 14 and the movable sleeve 16 slide against each other, and compress the spring 15 to buffer the impact force. At the same time, the movable sleeve 16 squeezes the rubber pad 18, and while the slide bar 10 slides in the slide groove 5, the inner wall of the slide groove 5 pushes the slide bar 10, so that the force block 6 rotates while moving, thereby moving to the bottom of another force block 6, so that The force-bearing block 6 no longer directly faces the impact force, so that the impacting object contacts the rubber pad 18, and the impact force is buffered again. During the movement of the force-bearing block 6, the fixed rod 14 and the movable sleeve 16 on the other force-bearing block 6 are pushed, so that some slides 12 slide in the movable groove 11, and then drive the slider 13 to move, so that the spring 15 on the slider 13 is compressed, and then the impact force is buffered again. Therefore, during use, the device can buffer and dampen the impact force multiple times, further improving the buffering and shock-absorbing effect of the device, improving the use effect of the device, being worthy of promotion, and improving the practicality of the device.

[0032] When the load block 6 is in motion, it pushes the fixed rod 14 and the movable sleeve 16 on the other load block 6, so that some slide plates 12 slide in the movable groove 11, thereby driving the slider 13 to move, thereby compressing the spring 15 on the slider 13, and then buffering the impact force.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
