The baffle plate 72 is connected to the mounting bracket 5 through the linkage assembly 73, the extension plate 71 and the baffle plate 72 at least partially overlap in the vehicle traveling direction, and the baffle plate 72 moves in the vehicle traveling direction along with the mounting bracket 5 and shields the gap between the frame body 21 and the mounting bracket 5.

Specifically, two ends of the mounting bracket 5 in the vehicle traveling direction are respectively provided with a shielding mechanism, that is, two ends of the mounting bracket 5 in the vehicle traveling direction are respectively provided with a baffle 72 and a linkage assembly 73, so that both ends of the mounting bracket 5 in the vehicle traveling direction and the gap between the frame body 21 can be shielded. The baffle 72 is disposed above the extension plate 71, and the extension plate 71 and the baffle 72 are at least partially overlapped in the vehicle traveling direction, that is, no matter how the mounting bracket 5 moves in the vehicle traveling direction, a part of the baffle 72 is always located above the extension plate 71 on the corresponding side, so as to ensure that no gap occurs between the baffle 72 and the extension plate 71. The link assembly 73 is connected between the barrier 72 and the mounting bracket 5 so that the movement of the mounting bracket 5 can be transmitted to the barrier 72 through the link assembly 73 to drive the barrier 72 to move, thereby eliminating a separate driving source for the barrier 72.

In other alternative embodiments, the follower mechanism may not be provided with the extension plate 71, and the baffle plate 72 is directly connected to the mounting frame 5, which will not be described herein.

As shown in fig. 16 and 17, the baffle plate 72 is provided between the frame body 21 and the extension plate 71, and the baffle plate 72 is slidable relative to the frame body 21 in the vehicle traveling direction. The linkage assembly 73 comprises a first connecting portion connected with the baffle 72, a second connecting portion connected with the mounting rack 5 and a linkage rod 731, two ends of the linkage rod 731 penetrate through the first connecting portion and the second connecting portion respectively, two ends of the linkage rod 731 are provided with limiting pieces, the first connecting portion and the second connecting portion are located between the two limiting pieces, and the limiting pieces are used for preventing the first connecting portion or the second connecting portion from being separated from the linkage rod 731.

Specifically, in this embodiment, the first connecting portion is a third ear plate 732 mounted on the baffle 72, the second connecting portion is a fourth ear plate 733 mounted on the mounting block 5, two ends of the linkage rod 731 are respectively provided with a first limiting member 734 and a second limiting member 735, the linkage rod 731 is disposed through the third ear plate 732 and the fourth ear plate 733, the third ear plate 732 is provided with a first through hole, the fourth ear plate 733 is provided with a second through hole, the linkage rod 731 is in clearance fit with the first through hole and the second through hole, the third ear plate 732 and the fourth ear plate 733 are disposed between the first limiting member 734 and the second limiting member 735 in the vehicle driving direction, that is, the first limiting member 734 is mounted on a side of the third ear plate 732 away from the fourth ear plate 733 along the vehicle driving direction, and the second limiting member is mounted on a side of the fourth ear plate 733 away from the third ear plate 732 along the vehicle driving direction.

The linkage assembly 73 is connected with the mounting frame 5, can follow the mounting frame 5 and move along the vehicle running direction synchronously, and then drives the baffle 72 connected with the linkage assembly 73 to move along the vehicle running direction, and a driving piece for driving the baffle 72 to move does not need to be arranged independently, so that the structure of the shielding mechanism is simplified, and the cost is reduced.

In the following, the operating principle of the shielding mechanism will be briefly described by taking the example of controlling the electric vehicle to move forward in combination with the shielding mechanism.

When the front and rear wheels of the electric automobile are correspondingly placed at the wheel placing positions of the front and rear lifting devices, the piston of the hydraulic cylinder extends out to drive the mounting frame 5 to move forwards, and then the electric automobile parked on the mounting frame 5 is driven to move forwards. During the forward movement of the mounting bracket 5, the fourth ear plate 733 of the mounting bracket 5 also moves forward. Since the linkage rod 731 is in clearance fit with the first through hole of the third ear plate 732 and the second through hole of the fourth ear plate 733, the fourth ear plate 733 on the mounting rack 5 can move on the linkage rod 731. That is, in the vehicle traveling direction, the distance between the third lug plate 732 and the fourth lug plate 733 at the front end of the mounting bracket 5 is drawn in, and the extension plate 71 extends more below the baffle plate 72. The fourth ear plate 733 located at the rear end of the mounting block 5 drives the third ear plate 732 to move forward through the second limiting member 735, and since the first limiting member 734 and the second limiting member 735 are both installed on the linkage rod 731, and the position of the linkage rod 731 is kept unchanged, the second limiting member 735 drives the first limiting member 734 to move forward through the linkage rod 731, and further drives the baffle plate 72 installed with the third ear plate 732 to move forward, and the baffle plate 72 extends out from the top plate 213 of the frame body 21.

As shown in fig. 17 and 18, the shielding mechanism further includes an elastic member disposed between the first connecting portion and the second connecting portion, and the elastic member is used for providing an acting force to separate the first connecting portion and the second connecting portion from each other. In the embodiment, the elastic member is arranged to realize that the first connecting portion and the second connecting portion can be automatically reset under the acting force of the elastic member after being compressed, so that the baffle 72 can be further ensured to always block the gap between the mounting frame 5 and the frame body 21.

The spring seat 737 can restrict the degree of freedom of displacement of the spring 736 in the vehicle height direction, and improve the stability of the spring 736.

In other embodiments, the elastic member may also be made of other elastic materials such as rubber; a spring seat 737 can be only sleeved on the linkage rod 731, and the spring seat 737 is connected with the third ear plate 732 or the fourth ear plate 733, so that a certain effect of restricting the displacement freedom of the spring 736 in the vehicle height direction can be achieved, and details are not repeated herein.

The state of the spring 736 when controlling the electric vehicle to move forward is further discussed below in conjunction with the spring 736 described above.

During the forward movement of the mounting bracket 5, the spring 736 at the front end of the mounting bracket 5 is compressed due to the distance drawn between the third and

fourth lug plates

732, 733. The spring 736 at the rear end of the mounting bracket 5 keeps the distance between the third and

fourth lug plates

732 and 733 at the rear end of the mounting bracket 5 constant by its own elastic force even though the relative position between the baffle plate 72 at the rear end of the mounting bracket 5 and the mounting bracket 5 is constant.

As shown in fig. 4, when the baffle plate 72 moves to shield the gap between the frame body 21 and the mounting bracket 5, a gap is also generated between the baffle plate 72 and the side wall 212 of the frame body 21, and the periphery of the top plate 213 is fixed to the side wall 212, which is equivalent to the edge of the top plate 213 shielding the gap between the baffle plate 72 and the side wall 212, thereby avoiding the occurrence of a bump when the vehicle switches between the baffle plate 72 and the side wall 212, preventing impurities such as dust from entering the interior of the front lifting device 13 through the gap between the baffle plate 72 and the side wall 212 of the frame body 21, and improving the dustproof effect.

The limiting sub-mechanism is used for limiting the baffle 72 to excessively move, so that the baffle 72 shields the installation groove 51, and normal use of the roller mechanism 3 arranged in the installation groove 51 is guaranteed.

The limiting sub-mechanism comprises a second sliding block 738 connected with the baffle plate 72 and a second sliding rail 739 connected with the frame body 21, the second sliding block 738 and the second sliding rail 739 are matched with each other, the second sliding rail 739 is horizontally arranged on the frame body 21 along the vehicle driving direction, the first end of the second sliding rail 739 is propped against the frame body 21, the second end of the second sliding rail 739 is provided with a limiting part 740 for preventing the second sliding block 738 from falling off, namely, one end of the second sliding rail 739 far away from the mounting groove 51 is arranged close to the side wall 212 of the frame body 21, and the movement of the second sliding block 738 towards one side far away from the mounting groove 51 in the vehicle driving direction is limited by the side wall 212 of the frame body 21.
