The bottom of the anti-collision chassis is generally not processed, which only serves to reduce the damage caused by friction. However, when the anti-collision chassis encounters stones, the stones may be stuck at the bottom of the anti-collision chassis.

The front and rear enclosures and the side enclosures of the protection unit block collisions around, achieving the purpose of protection, and a base is installed at the bottom, wherein the rollers at the bottom of the base facilitate the discharge of stones stuck at the bottom, reducing the impact of the stones on the base.

[0041] The side wall buffer unit 200 includes an extrusion plate 201, one side of the extrusion plate 201 is in contact with the inner wall of the front and rear enclosures 101, a push plate 2012 is installed on the extrusion plate 201, a slide plate 202 is installed on the push plate 2012, a limit rod 2021 is slidably arranged inside the slide plate 202, a support seat 2023 is installed at the end of the limit rod 2021, and the support seat 2023 is installed on the base 105, a buffer spring 2022 is sleeved on the limit rod 2021, one end of the buffer spring 2022 is clamped on the slide plate 202, and the other end of the buffer spring 2022 is clamped on the support seat 2 023, a push rod 2042 is installed on the support seat 2023, and both ends of the push rod 2042 are connected to the side enclosures 102 on both sides.

The bottom of the top block 303 is in contact with the base 105, and the top block 303 corresponds to the front and rear enclosures 101 after rotating ninety degrees. When the stone is stuck in the base, the top block on the turntable has a downward squeezing force on the base to ensure that the base will not be deformed. After the front and rear enclosures collide, the push plate moves to drive the bar groove to move, and then the protrusion drives the turntable to rotate. The turntable rotates the top block ninety degrees so that the top block can correspond to the extrusion plate, ensuring that after the extrusion plate is deformed to the top block, the top block can prevent the extrusion plate from continuing to deform, reducing the harm caused by the extrusion plate invading the battery pack.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in a specific embodiment, a cover plate 103 is installed on the front and rear enclosures 101, and the cover plate 103 covers the cavity formed by the front and rear enclosures 101, the side enclosures 102 and the base 105. The bottom of the cover plate 103 and the support seat 2023 are connected to each other, and a protective cover 106 is installed on the top of the front and rear enclosures 101.

Bolts are passed through the positioning holes 1043 to mount the device as a whole on the bottom of the chassis of the vehicle, wherein the front and rear enclosures 101 face the front and rear of the vehicle, and the side enclosures 102 correspond to the sides of the vehicle.

[0045] Embodiment 2:

[0046] The difference between the above embodiment and this embodiment is that: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the bottom of the base 105 is provided with a plurality of pairs of through holes 1051, and a synchronous shaft 1052 is movably installed inside the plurality of pairs of through holes 1051, and a plurality of pairs of rollers 1053 are installed on the synchronous shaft 1052, and the plurality of pairs of rollers 1053 are respectively placed in the through holes 1051, and the height of the rollers 1053 penetrates the thickness of the base 105, and the side walls of the front and rear enclosures 101 are provided with bevels 1011, and a plurality of pairs of reinforcing rods are installed on the surface of the bevels 1011. At this time, the soil blocks on the uneven road surface are guided to the bottom of the base 105 through the bevels 1011, and at this time, the rollers 1053 on the synchronous shaft 1052 can play a guiding role, ensuring that the vehicle can travel normally, and the structural strength is improved through the reinforcing rods, so that the wear is reduced.

[0047] like Figure 5 and Figure 6As shown, in a specific embodiment, a fixing block 2011 is welded to one side of the extrusion plate 201, and the side wall of the fixing block 2011 is welded to the front and rear enclosures 101, and a limiting seat 3022 is fixedly installed on the base 105, and the limiting seat 3022 is connected to the limiting rod 2021. When the front end of the automobile chassis collides with stones or debris on the road, the front and rear enclosures 101 may be deformed, thereby driving the extrusion plate 201 welded with the fixing block 2011 to move inward, wherein the extrusion plate 201 drives the push plate 2012 at the end to slide, and the slide plate 202 on the push plate 2012 slides on the limiting rod 2021 on the support seat 2023.

[0048] like Figure 6 , Figure 8 and Fig. 9 As shown, further, a positioning sleeve 205 is installed on the limiting seat 3022, and a partition 2053 is slidably arranged inside the positioning sleeve 205, and a positioning rod 2051 is installed inside the partition 2053, and the positioning rod 2051 penetrates the positioning sleeve 205, and the end of the positioning rod 2051 is connected to the slide plate 202, and a tension spring 2052 is arranged inside the positioning sleeve 205, one end of the tension spring 2052 is connected to the inside of the positioning sleeve 205, and the other end of the tension spring 2052 is connected to the partition 2053, and the stretching direction of the tension spring 2052 is the same as the movement of the positioning rod 2051. During the movement of the slide plate 202, the positioning rod 2051 of the slide plate 202 pulls the partition 2053 to slide inside the positioning sleeve 205, and the partition 2053 and the inner wall of the positioning sleeve 205 are clamped with the tension spring 2052, and the tension spring 2052 is stretched as a whole at this time, so as to further convert the impact force generated by the collision.

[0049] Embodiment 3:

[0050] The difference between the above embodiment and this embodiment is that: Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, a swing arm 204 is movably hingedly installed on the skateboard 202, and the swing arm 204 is in an inclined state. A sliding sleeve 2041 is movably installed at the end of the swing arm 204, and the sliding sleeve 2041 slides on the top rod 2042. An auxiliary seat 2043 is installed on the top rod 2042, and the auxiliary seat 2043 is installed on the base 105. An auxiliary spring 2044 is sleeved on the top rod 2042, and one end of the auxiliary spring 2044 is clamped on the side wall of the auxiliary seat 2043, and the other end of the auxiliary spring 2044 is clamped on the sliding sleeve 2041. When the slide plate 202 moves, the position of the swing arm 204 on the slide plate 202 changes, and the sliding sleeve 2041 at the end of the swing arm 204 slides inside the top rod 2042. The two ends of the top rod 2042 are fixed on the side enclosure 102 to ensure that the structural strength of the side enclosure 102 can be guaranteed during the collision. An auxiliary seat 2043 is installed on the top rod 2042. At this time, an auxiliary spring 2044 is clamped on the auxiliary seat 2043 and the sliding sleeve 2041. The above equipment ensures that the entire slide plate 202 moves horizontally, and the auxiliary spring 2044 is used to facilitate later resetting.

[0051] like Figure 6 , Figure 7 and Figure 8 As shown, in a specific embodiment, a positioning seat 3021 is installed on the limiting seat 3022, and a rotating shaft 302 is rotatably installed on the positioning seat 3021. The two ends of the rotating shaft 302 are respectively connected to the rotation center of the rotating disk 301. A torsion spring 3023 is sleeved on the rotating shaft 302, and one end of the torsion spring 3023 is clamped on the rotating disk 301, and the other end of the torsion spring 3023 is clamped on the positioning seat 3021. During the rotation of the rotating disk 301, the rotating shaft 302 on the rotating disk 301 rotates on the positioning seat 3021, and the positioning seat 3021 is installed on the limiting seat 3022. During the rotation of the rotating disk 301, the torsion spring 3023 clamped on the surface is twisted synchronously, and the twisted torsion spring 3023 is convenient for later reset.

[0052] According to the above embodiment, an automobile chassis is provided, and the above anti-collision structure is installed at the lower part of the automobile chassis.

[0053] The implementation principle of a new energy vehicle chassis anti-collision structure and vehicle chassis of this embodiment is as follows:

[0054] First, the operator needs to install the entire device through the mounting plate 104 so that the protective cover 106 is completely wrapped around the outside of the battery pack, and bolts are passed through the positioning holes 1043 to install the entire device at the bottom of the car chassis, with the front and rear enclosures 101 facing the front and rear of the car, and the side enclosures 102 corresponding to the sides of the car.

[0055] When the car is running on an uneven road, the chassis of the car may be scratched. At this time, the dirt on the uneven road is guided to the bottom of the base 105 through the bevel 1011. At this time, the roller 1053 on the synchronous shaft 1052 can play a guiding role to ensure that the vehicle can run normally.

[0056] When the bottom of the base 105 is squeezed by the stone, the base 105 may be deformed. However, the top block 303 is now in a vertical state as a whole, so there is a downward squeezing force on the base 105, which reduces the possibility of deformation of the base 105 and further improves the support effect through the support seat 2023.

[0057] When the front end of the automobile chassis collides with stones or debris on the road, the front and rear guards 101 may be deformed, thereby driving the extrusion plate 201 welded with the fixing block 2011 to move inward, wherein the extrusion plate 201 drives the push plate 2012 at the end to slide, and the slide plate 202 on the push plate 2012 slides on the limit rod 2021 on the support seat 2023, and pushes the buffer spring 2022 to be compressed, thereby converting the impact force of the collision into the elastic force of the spring for preservation, thereby reducing the impact force of the collision.

[0058] The top block 303 of the bottom can be rotated to correspond to the extrusion plate 201, so that the extrusion plate 201 will not continue to deform after the extrusion plate 201 is deformed and moved to the top block 303, thereby reducing the harm caused by the extrusion plate 201 invading the battery pack. During the rotation of the turntable 301, the rotating shaft 302 on the turntable 301 rotates on the positioning seat 3021, and the positioning seat 3021 is installed on the limit seat 3022. During the rotation of the turntable 301, the torsion spring 3023 clamped on the surface is twisted synchronously, and the twisted torsion spring 3023 is convenient for later resetting.

[0059] During the movement of the skateboard 202, the positioning rod 2051 of the skateboard 202 pulls the partition 2053 to slide inside the positioning sleeve 205, and the partition 2053 and the inner wall of the positioning sleeve 205 are clamped with a tension spring 2052. At this time, the tension spring 2052 is stretched as a whole, thereby further converting the impact force generated by the collision.

[0060] When the slide plate 202 moves, the position of the swing arm 204 on the slide plate 202 changes, and the sliding sleeve 2041 at the end of the swing arm 204 slides inside the top rod 2042. The two ends of the top rod 2042 are fixed on the side enclosure 102 to ensure that the structural strength of the side enclosure 102 can be guaranteed during the collision. An auxiliary seat 2043 is installed on the top rod 2042. At this time, an auxiliary spring 2044 is clamped on the auxiliary seat 2043 and the sliding sleeve 2041. The above equipment ensures that the entire slide plate 202 moves horizontally, and the auxiliary spring 2044 is used to facilitate later resetting.
