Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] Example 1:

[0025] like Figure 1-4 As shown, the utility model discloses a vehicle side impact protection structure, comprising a protection beam 3, with connecting plates 2 fixed at both ends of the protection beam 3, and an energy absorbing component detachably connected to the connecting plate 2;

[0026] The energy absorption assembly includes an energy absorption box 1, which is a multi-layer hollow tower. The bottom of the energy absorption box 1 is detachably connected to the side of the connecting plate 2 away from the protective beam 3. Energy absorption grooves 5 are arranged between each layer of the tower structure of the energy absorption box 1, and the energy absorption grooves 5 are arranged around the tower.

[0027] In this embodiment, the energy absorption box 1 is a three-layer hollow tower, each layer of the tower is a cube structure, and the energy absorption groove 5 is a square annular groove.

[0028] The shape of the energy absorption groove 5 of the utility model changes according to the change of the tower body structure. The hollow energy absorption box 1 and the arrangement of the energy absorption groove 5 make it convenient for the energy absorption box 1 to collapse and deform inward after the vehicle is hit from the side, and the upper tower is concave toward the lower tower, and the layers are stacked to absorb the energy of the impact and reduce the deformation of the vehicle body.

[0029] In this embodiment, two fixing blocks 4 for connecting to the vehicle frame are evenly distributed on the protective crossbeam 3 .

[0030] In this embodiment, extensions 9 are provided on both sides of the top of the fixing block 4. The extensions 9 protrude upward, thereby increasing the contact area between the fixing block 4 and the connecting block 8, facilitating fixed connection with the vehicle frame 7, and making the connection more stable.

[0031] In this embodiment, the bottom of the energy absorption box 1 and the side of the connecting plate 2 away from the protective beam 3 are detachably connected by bolts.

[0032] The energy absorption box 1 of the utility model is fixed to the connecting plate by bolts. If a small collision occurs, the energy absorption box 1 is deformed to absorb energy, so that the energy absorption box 1 can be easily replaced.

[0033] In this embodiment, a plurality of collapse inducing grooves 6 are respectively provided at both ends of the protective beam 3 .

[0034] In this embodiment, two crush inducing grooves 6 are respectively provided at both ends of the protective beam 3, so that the protective beam 3 can participate in collision energy absorption and enhance the energy absorption capacity. When the energy absorption box 1 reaches the upper limit of its bearing capacity, the crush inducing grooves 6 continue to absorb energy, further reducing the impact of the collision energy on the interior of the vehicle and improving the side collision resistance.

[0035] In this embodiment, the protective beam 3 is a round steel pipe with an outer diameter of 30-50 mm.

[0036] In this embodiment, the wall thickness of the protective beam 3 is 1.8-3 mm.

[0037] In this embodiment, the vehicle side impact protection structure is placed between the frames 7, the top of the energy absorption box 1 is in contact with the inner side of the B-pillar of the frame, two connecting blocks 8 are fixed to the bottom of the frame 7, the protective beam 3 passes through the connecting blocks 8, and through grooves for embedding the extension parts 9 are opened on both sides of the connecting blocks 8. The fixing blocks 4 are welded to the connecting blocks 8.

[0038] The working principle of the present utility model is as follows: when in use, after a side collision of the vehicle occurs, the protective crossbeam 3 connected to the frame 7 through the fixed block 4 absorbs energy, and the energy absorption boxes 1 at both ends of the protective crossbeam 3 first absorb the energy of the impact, and the hollow tower-shaped energy absorption box 1 collapses and deforms inward after the collision, and then the collapse induction groove 6 on the protective crossbeam 3 participates in the energy absorption and collapses and deforms, reducing the deformation of the vehicle body, thereby reducing the damage to the occupants in the vehicle caused by the collision, thereby achieving the purpose of improving the vehicle's anti-side collision strength and occupant safety protection.

[0039] The utility model does not require the development of new vehicle body molds and axles. It only requires fixing the protective crossbeam 3 to the bottom of the frame 7 so that its two ends respectively support the two sides of the frame 7. This can absorb energy when the vehicle collides sideways, improve the side collision resistance, and thus better protect the occupants of the vehicle.
