[0022] Refer to Figures 1-3 , the long slide rail moving mechanism 3 in this embodiment includes: two first slide rails 301 arranged along the X direction of the vehicle, a first slider 302 slidably connected to the first slide rails 301, and a first driving motor 303 for driving the first slider 302 to slide on the first slide rails 301. The two first slide rails 301 are fixedly connected to the vehicle body bracket in parallel. Inside the two first slide rails 301, a first long lead screw is rotatably connected along the X direction respectively. A first steering gear (bevel gear) is screwed on the first long lead screw. The first steering gear meshes with a second steering gear on the first synchronizing rod 307 driven by the first driving motor 303. The meshing of the first steering gear and the second steering gear can realize the power transmission in the vertical direction. The first driving motor 303 indirectly drives the two first long lead screws to rotate through the first synchronizing rod 307, two first steering gears and two second steering gears. The lead screw nut at the bottom of the first slider 302 is rotatably connected to the first long lead screw. The rotating first long lead screw drives the first slider 302 to slide back and forth on the first slide rails 301.
[0023] Refer to Figure 3, the present embodiment further includes a first locking motor 306. The first locking motor 306 is used to control the locking of the first slide rail 301 and the first slider 302. Only after the first locking motor 306 is unlocked can the first driving motor 303 drive the first slider 302 to slide on the first slide rail 301. Two paddles are provided on the second synchronizing rod 304 driven by the first locking motor 306. Locking grooves are provided on the two first slide rails 301, and locking seats are provided on the two first sliders 302. The locking tongues on the locking seats are rotatably connected to the locking seats through rotating shafts. A return spring for resetting the locking tongues is sleeved on the locking seats. One end of the locking tongue is clamped in the locking groove. The first locking motor 306 uses the paddles on the second synchronizing rod 304 to toggle the locking tongue to separate the locking tongue from the locking groove.
[0024] Refer to Figure 1 , Figure 4 and Figure 5 , a first connecting seat 305 is provided on the first slider 302 in the present embodiment.
