[0028] Example 1

[0029] The embodiment of the present invention provides an impact-resistant frame structure, such as Figure 1-Figure 5 As shown, it comprises: a frame body 1, at least one end of the frame body 1 is provided with an impact-resistant device, the impact-resistant device comprises an impact-resistant beam 2, an impact-resistant component is provided at one end of the impact-resistant beam 2 away from the frame body 1, the impact-resistant beam 2 is connected to the frame body 1 through a connecting component, and an energy-absorbing component is provided between the impact-resistant beam 2 and the frame body 1;

[0030] A plurality of cross beams 3 for support are arranged inside the frame body 1, and the plurality of cross beams 3 are parallel to each other.

[0031] The working principle and beneficial effects of the above technical solution are as follows: In the present invention, an anti-impact device is arranged at least at one end of the frame body 1, and the anti-impact device can be arranged on the front and the rear of the frame body 1. When the frame body 1 is hit from the front, the anti-impact component on one side of the anti-impact beam 2 first contacts the collision object, and the anti-impact component can absorb the energy in the collision impact process, and the anti-impact component drives the anti-impact beam 2 to move towards the frame body 1 under the impact force, and further absorbs the energy of the impact through the energy-absorbing component, so as to avoid the impact effect caused by the collision directly acting on the frame body 1, thereby improving the anti-impact ability of the frame body 1, avoiding large deformation of the frame body 1 due to the collision, effectively protecting the components on the frame body 1, and ensuring the personal safety of the driver and passengers. A plurality of cross beams 3 are arranged in the frame body 1, and the cross beams 3 can improve the stability and strength of the structure of the frame body 1, and the cross beams 3 can play a supporting role, so as to facilitate the installation of other components on the frame body 1 and improve the supporting performance of the frame body 1.

[0032] Example 2

[0033] On the basis of the above-mentioned embodiment 1, Figure 1 As shown, the impact-resistant assembly includes several layers of elastic steel plates 4 , the concave side of the elastic steel plates 4 faces the impact-resistant beam 2 , and the two ends of the elastic steel plates 4 are respectively connected to the two ends of the impact-resistant beam 2 .

[0034] The working principle and beneficial effects of the above technical solution are as follows: the elastic steel plate 4 has high elasticity. When the front of the frame body 1 is hit, the impacting object first contacts the elastic steel plate 4 and drives the elastic steel plate 4 to bend toward the direction close to the anti-impact beam 2. The high elasticity of multiple elastic steel plates 4 buffers the impact force, which has a protective effect on the front of the frame body 1.

[0035] Example 3

[0036] On the basis of Example 1 or 2, Figure 1 , Figure 2As shown, the energy absorption assembly includes a movable column 5, and two movable columns 5 are symmetrically arranged at the front and rear ends of the anti-impact beam 2. The movable columns 5 are perpendicular to the anti-impact beam 2. An energy absorption tube 6 corresponding to the movable column 5 is arranged at one end of the frame body 1 close to the anti-impact beam 2. The end of the movable column 5 away from the anti-impact beam 2 is inserted into the energy absorption tube 6 and contacts with the sliding plate 7. The sliding plate 7 is slidably connected to the inner wall of the energy absorption tube 6, and the sliding plate 7 is connected to the inner wall of the energy absorption tube 6 away from the movable column 5 through a first elastic element 8.

[0037] The working principle and beneficial effects of the above technical solution are as follows: when impacted by an external object, the anti-impact beam 2 moves toward the direction close to the frame body 1, the anti-impact beam 2 drives the movable column 5 to move in the energy absorbing cylinder 6, and the movable column 5 drives the sliding plate 7 to slide in the energy absorbing cylinder 6, thereby driving the first elastic element 8 to compress. The first elastic element 8 can be a spring. The compression of the first elastic element 8 further reduces the energy generated by the impact, improves the impact resistance of the frame body 1, effectively protects the frame body 1, avoids large deformation of the frame body 1, and effectively protects the components installed on the frame body 1.

[0038] Example 4

[0039] On the basis of any one of Examples 1-3, Figure 1-Figure 5 As shown, the connection assembly includes a first connection beam 9 and a second connection beam 10, the cross-sections of the first connection beam 9 and the second connection beam 10 are of a square structure, the second connection beam 10 is sleeved outside the first connection beam 9, one end of the first connection beam 9 is centrally connected to one end of the frame body 1, one end of the second connection beam 10 is centrally connected to the anti-impact beam 2 close to the side of the frame body 1, and a clamping mechanism is provided between the first connection beam 9 and the second connection beam 10, and the clamping mechanism is used to clamp the second connection beam 10 to the outside of the first connection beam 9;

[0040] The clamping mechanism includes sliding holes 11 arranged on both sides of the first connecting beam 9, a sliding block 12 is slidably arranged in the sliding hole 11, one end of the sliding block 12 extends to the inside of the first connecting beam 9 and is provided with a limit plate 13, the limit plate 13 is connected to the inner wall of the first connecting beam 9 through a compression spring 14, a clamping hole 15 is arranged at one end of the sliding block 12 near the second connecting beam 10, a first clamping block 16 is slidably arranged in the clamping hole 15, the first clamping block 16 is connected to the clamping hole 15 through a connecting spring, the first clamping block 16 is in the shape of a right-angled trapezoid, and the inner side of the second connecting beam 10 is provided with a clamping hole 15. A second clamping block 17 corresponding to the first clamping block 16, an elastic sheet 18 is arranged inside the first connecting beam 9, the elastic sheet 18 is M-shaped, and both ends of the elastic sheet 18 are respectively connected to the inner wall of the end of the first connecting beam 9 away from the anti-impact beam 2, the elastic sheet 18 includes a first arc segment 19 and a second arc segment 20, the first arc segment 19 is arranged in the middle position of the elastic sheet 18 and protrudes away from the end of the anti-impact beam 2, the two second arc segments 20 are symmetrically arranged on both sides of the first arc segment 19, and the second arc segment 20 abuts against the end of the limit plate 13 away from the slider 12;

[0041] A first inclined surface is provided on the side of the first clamping block 16 close to the second connecting beam 10, a length of the first clamping block 16 close to the end of the anti-impact beam 2 is less than a length of the first clamping block 16 away from the end of the anti-impact beam 2, and a second inclined surface adapted to the first inclined surface is provided on the side of the second clamping block 17 close to the first connecting beam 9;

[0042] A buffer assembly is arranged in the second connecting beam 10, and the buffer assembly includes a buffer cylinder 21, one end of the buffer cylinder 21 is connected to the middle position of the impact-resistant beam 2, a buffer plate 22 is slidably arranged in the buffer cylinder 21, and the buffer plate 22 is connected to the inside of the buffer cylinder 21 through a buffer spring 23. A contact rod 24 is arranged at one end of the buffer plate 22 close to the elastic sheet 18, and the contact rod 24 extends to the outside of the buffer cylinder 21 close to the elastic sheet 18 and is aligned with the first arc segment 19.

[0043] The working principle and beneficial effects of the above technical solution are as follows: in the initial state, the first connecting beam 9 is fixedly connected to the frame body 1, the elastic sheet 18 in the first connecting beam 9 is in an expanded state, and the second arc segments 20 on both sides of the elastic sheet 18 abut against the limit plate 13 under the action of elastic force. At this time, the compression spring 14 is in a compressed state, and one end of the first clamping block 16 extends to the outside of the sliding hole 11. When the anti-impact beam 2 is installed to one end of the frame body 1, the center of the second connecting beam 10 is first aligned with the center of the first connecting beam 9, the movable column 5 is aligned with the energy absorbing cylinder 6, and then the second connecting beam 10 is sleeved on the outside of the first connecting beam 9, and the second clamping block 17 on the inner wall of the second connecting beam 10 slides along the outer wall of the first connecting beam 9. When the second clamping block 17 passes through the first clamping block 16, The second inclined surface of the second clamping block 17 slides along the first inclined surface of the first clamping block 16, and drives the first clamping block 16 to slide into the clamping hole 15, and the connecting spring is compressed. When the second clamping block 17 passes through the first clamping block 16, the first clamping block 16 returns to its original position under the elastic force of the connecting spring. At this time, the anti-impact beam 2 is installed. Under the elastic force of the energy absorbing component, the side of the second clamping block 17 close to the anti-impact beam 2 contacts the side of the first clamping block 16 away from the anti-impact beam 2, and under the clamping of the first clamping block 16 and the second clamping block 17, the anti-impact beam 2 cannot be separated from the frame body 1, thereby realizing the rapid installation of the anti-impact beam 2. When the front side of the frame body 1 is subjected to the impact force generated by the collision, the first energy absorption is performed by the anti-impact component, and at the same time At the same time, the energy absorption component performs a second energy absorption, thereby reducing the impact force received by the frame body 1. At the same time, when the anti-impact beam 2 is subjected to the impact force and moves toward the frame body 1, the anti-impact beam 2 drives the buffer cylinder 21 to move toward the elastic sheet 18, and the buffer cylinder 21 drives the contact rod 24 to move toward the first arc segment 19 close to the elastic sheet 18. When the contact rod 24 contacts the first arc segment 19, the contact rod 24 drives the buffer plate 22 to slide in the buffer cylinder 21, and the buffer spring 23 is compressed, thereby further buffering the impact force and reducing the impact force. When the impact force is too large, the buffer spring 23 is compressed to a preset length, and the contact rod 24 drives the first arc segment 19 of the elastic sheet 18 to move away from the anti-impact beam 2. The first arc segment 1 9 drives the second arc segments 20 on both sides to deflect toward the direction of the buffer tube 21. Under the action of the compression spring 14, the limit plate 13 moves toward the direction of the buffer tube 21. The limit plate 13 drives the slider 12 to slide in the sliding hole 11, so that the first clamping block 16 completely enters the sliding hole 11. At this time, the elastic sheet 18 is in a contracted state. The elastic force of the elastic sheet 18 further reduces the impact force and improves the impact resistance. When the impact force on the frame body 1 is too large, the elastic steel plate 4 is easily damaged and cannot be restored. At this time, a new elastic steel plate 4 needs to be replaced. Since the elastic sheet 18 is in a contracted state, the first clamping block 16 is located in the sliding hole 11. At this time, the second clamping block 17 will not be blocked, and the anti-impact beam 2 is pulled away from the frame body 1.The second connecting beam 10 can be separated from the first connecting beam 9, which is convenient for repairing or replacing the anti-impact beam 2 or the elastic steel plate 4, ensuring the anti-impact performance of the anti-impact device. At the same time, the elastic sheet 18 in the first connecting beam 9 can be replaced. The elastic sheet 18 has a low cost and can reduce the manufacturing cost of the frame body 1. By setting the connecting assembly, not only the anti-impact beam 2 and the frame body 1 are quickly connected, which is convenient for disassembling and assembling the anti-impact beam 2 and improving the maintenance efficiency, but also the elastic force of the buffer spring 23 and the elastic sheet 18 further reduces the impact force caused by the collision, improves the anti-impact ability of the frame body 1, reduces the damage to the frame body 1, prevents the frame body 1 from being greatly deformed, and extends the service life of the frame body 1.

[0044] Example 5

[0045] On the basis of Example 4, Figure 1-Figure 5 As shown, a side protection assembly is arranged on the outer side of the frame body 1, and the side protection assembly includes side protection plates 25 symmetrically arranged on both sides of the impact-resistant beam 2, and the side protection plates 25 are connected to the cross beam 3 through two first connecting rods 26, and the two first connecting rods 26 are parallel to each other, one end of the first connecting rod 26 is rotatably connected to the cross beam 3, and the other end of the first connecting rod 26 is rotatably connected to the inner wall of the side protection plate 25, and the side protection plate 25 is driven by a driving mechanism;

[0046] The driving mechanism includes a movable plate 27 arranged outside the first connecting beam 9, and the movable plate 27 is slidably connected to the outer wall of the first connecting beam 9. Two driving plates 28 are arranged on the side of the movable plate 27 close to the frame body 1. The two driving plates 28 are symmetrically arranged about the center line of the first connecting beam 9. The driving plate 28 is connected to the fixed plate 30 through the second elastic element 29. The fixed plate 30 is arranged on the frame body 1. The driving plate 28 is connected to one of the first connecting rods 26 through the second connecting rod 31. One end of the second connecting rod 31 is rotatably connected to the middle position of the first connecting rod 26, and the other end of the second connecting rod 31 is rotatably connected to the driving plate 28.

[0047] The working principle and beneficial effects of the above technical solution are as follows: when the anti-impact beam 2 is impacted and moves toward the frame body 1, the anti-impact beam 2 drives the second connecting beam 10 to move, and the second connecting beam 10 drives the movable plate 27 to slide outside the first connecting beam 9, and the movable plate 27 drives the driving plate 28 to move toward the fixed plate 30. At this time, the second elastic element 29 is compressed. The second elastic element 29 can be a spring. Through the elastic force of the second elastic element 29, the impact force is further alleviated and the impact resistance is improved. At the same time, the sliding of the driving plate 28 can drive the second connecting rod 31 to move, and the second connecting rod 31 drives the first connecting rod 26 to rotate. Under the action of the two mutually parallel first connecting rods 26, the side guard plate 25 moves away from the frame body 1, and the two side guard plates 25 are unfolded, thereby protecting both sides of the frame body 1 to avoid secondary damage caused by collision on the side of the frame body 1, thereby further improving the safety and impact resistance of the frame body 1.
