Heat dissipation grooves are provided on the inner walls of the left and right ends of the shell 1 to facilitate the heat dissipation of the electric controller. The upper inner wall of the shell 1 is slidably connected with a bearing plate 7, and the bearing plate 7 slides on the upper inner wall of the shell 1 to support the electric controller. A cylinder 9 is fixedly connected to the outer wall of the bottom end of the bearing plate 7. The cylinder 9 plays a connecting role and is used to connect the bearing plate 7 and the connecting ring 8. The inner wall of the bottom end of the cylinder 9 is slidably connected to the outer wall of the limit rod 10, and the outer wall of the bottom end of the cylinder 9 is slidably connected to the inner wall of the upper end of the shell 1. The cylinder 9 A connecting ring 8 is fixedly connected to the outer wall, and a rotation groove may be provided on the lower inner wall of the front end and the rear end of the connecting ring 8. The connecting ring 8 provides support for the rotation of the connecting rod 11. A connecting rod 11 is rotatably connected to the inner wall of the front end of the connecting ring 8. The front end outer wall of the connecting rod 11 is rotatably connected to the inner wall of the upper end of the slider 12. The connecting rod 11 is used to connect the connecting ring 8 and the slider 12. The slider 12 is elastically connected to the inner wall of the front end of the shell 1 through a spring 13. When the electric controller moves downward due to vibration, it drives the bearing plate 7 to move downward, and pushes the slider 12 forward through the cylinder 9, the connecting ring 8 and the connecting rod 11, squeezing the spring 13 to provide a buffer space for the downward movement of the electric controller.

[0032] Furthermore, one end of the spring 13 is fixedly connected to the front end inner wall of the shell 1, and the other end of the spring 13 is fixedly connected to the front end outer wall of the slider 12. The upper end inner wall of the shell 1 is fixedly connected to a limit rod 10, and the outer wall of the limit rod 10 is slidably connected to the inner wall of the spring 13. The outer wall of the limit rod 10 is slidably connected to the inner wall of the slider 12. The limit rod 10 provides a guide for the sliding of the slider 12. A cover plate 4 is rotatably connected to the outer wall of the upper right end of the shell 1. The cover plate 4 can close the upper end opening of the shell 1 to prevent the electric controller in the shell 1 from falling out of the shell 1. The left end inner wall of the cover plate 4 The wall is elastically connected with a pressure plate 3 through a spring 26. The left outer wall of the pressure plate 3 contacts the upper outer wall of the electric controller, and the vibration of the electric controller is buffered by cooperating with the spring 26. The pressure plate 3 is arranged in an I-shape, and the outer wall of the pressure plate 3 is slidably connected to the left inner wall of the cover plate 4. The spring 26 applies elastic force to the right outer wall of the pressure plate 3, so that the left outer wall of the pressure plate 3 is always in contact with the upper outer wall of the electric controller. One end of the spring 26 is fixedly connected to the left inner wall of the cover plate 4, and the other end of the spring 26 is fixedly connected to the right outer wall of the pressure plate 3. An auxiliary component is rotatably connected to the front inner wall of the shell 1.

[0033] Reference Figure 2-Figure 4The auxiliary component includes a heat sink 2, which is symmetrically arranged. The heat sink 2 is released by moving the insert block 14, and the heat sink 2 is rotated ninety degrees clockwise to lift the carrier plate 7 upward, which is convenient for taking and placing the electric controller. The bottom outer wall of the heat sink 2 is rotatably connected to the front inner wall of the shell 1. The front inner wall of the shell 1 is elastically connected with the insert block 14 through the spring three 5. The heat sink 2 is released by moving the insert block 14 upward. The heat sink 2 can be rotated ninety degrees clockwise to lift the carrier plate 7 upward. The rear end outer wall of the heat sink 2 contacts the bottom outer wall of the carrier plate 7, so that the carrier plate 7 is fixed in this position, and the electric controller can be placed on the carrier plate 7. The needle rotates the heat sink 2, and the electric controller is driven to move into the shell 1 through the carrying plate 7. The heat sink 2 rotates counterclockwise, and the outer wall of the heat sink 2 squeezes the front end inclined surface of the insert 14, and the insert 14 retracts to the front end inner wall of the shell 1. After the heat sink 2 rotates counterclockwise by ninety degrees, the insert 14 pops out and is connected to the upper end inner wall of the heat sink 2 to fix the heat sink 2. The front end outer wall of the insert 14 is arranged in an inclined shape, and the bottom end outer wall of the insert 14 is slidably connected to the front end inner wall of the shell 1, and the bottom end outer wall of the insert 14 is slidably connected to the upper end inner wall of the heat sink 2. One end of the spring three 5 is fixedly connected to the front end inner wall of the shell 1, and the other end of the spring three 5 is fixedly connected to the upper end outer wall of the insert 14.

[0034] Working principle: By moving the insert block 14 upward to release the limit on the heat sink 2, the heat sink 2 can be rotated 90 degrees clockwise to lift the carrier plate 7 upward, and the rear end outer wall of the heat sink 2 contacts the bottom end outer wall of the carrier plate 7, so that the carrier plate 7 is fixed in this position, and the electric controller can be placed on the carrier plate 7, and the heat sink 2 is rotated counterclockwise to drive the electric controller into the housing 1 through the carrier plate 7. The heat sink 2 rotates counterclockwise, and the outer wall of the heat sink 2 squeezes the front end inclined surface of the insert block 14, and the insert block 14 retracts to the front end inner wall of the housing 1. After the heat sink 2 rotates counterclockwise by 90 degrees, the insert 14 pops out and snaps onto the inner wall of the upper end of the heat sink 2 to fix the heat sink 2. The cover plate 4 is rotated to seal the upper end opening of the shell 1. The spring 2 6 applies elastic force to the right end outer wall of the pressure plate 3, so that the left end outer wall of the pressure plate 3 contacts the upper end outer wall of the electric controller. When the electric controller moves downward under vibration, it drives the bearing plate 7 to move downward, and pushes the slider 12 forward through the cylinder 9, the connecting ring 8 and the connecting rod 11, squeezing the spring 13 to provide a buffer space for the downward movement of the electric controller.
