[0036] As shown in the atta Figure 1As shown in the coordinate system, the X, Y, and Z directions in the coordinate system are based on the vehicle coordinate system. The vehicle coordinate system is a special moving coordinate system used to describe the movement of the vehicle. The origin of this coordinate system coincides with the center of mass of the vehicle. When the vehicle is stationary on a horizontal road surface, the X direction of this coordinate system refers to the direction parallel to the driving direction of the vehicle, that is, the front-back direction, where the direction indicated by the arrow is the front. The Y direction refers to the width direction of the vehicle, that is, the left-right direction, where the direction indicated by the arrow is the left. The Z direction refers to the height direction of the vehicle, that is, the up-down direction, where the direction indicated by the arrow is the up.

[0037] The above-mentioned coordinate system is intended to illustrate the approximate positional relationship, connection relationship, or movement relationship of each component, and does not mean that each component in the present utility model needs to be strictly set or connected according to the above coordinate system. Those skilled in the art can flexibly adjust according to actual needs.

[0038] Combined with the attached Figure 1 and the attached Figure 2 , the vehicle tail energy absorption assembly proposed by the present utility model includes a rear bumper 10, a crash beam 20, and a buffer member 30. The rear bumper 10 and the crash beam 20 are distributed in the front-back direction, and the rear bumper 10 is located behind the crash beam 20. The rear bumper 10 and the crash beam 20 are respectively connected to the vehicle body. Two buffer members 30 are distributed in the left-right direction between the rear bumper 10 and the crash beam 20 and are detachably connected to the crash beam 20. Combined with the attached Figure 3 , the buffer member 30 includes a main body 31. An energy absorption column 311 protrudes from the rear side of the main body 31. The energy absorption column 311 protrudes and extends toward the side close to the rear bumper 10. A cavity 312 is provided on the side of the energy absorption column 311 close to the crash beam 20. The main body 31 is provided with a first mounting portion and a second mounting portion. The main body 31 is detachably connected to the crash beam 20 in the up-down direction through the first mounting portion, and the main body 31 is detachably connected to the crash beam 20 in the left-right direction through the second mounting portion.

[0039] In one example, the rear end of the energy absorption column 311 contacts the rear bumper 10. With this setting, it can play a structural support role for the rear bumper 10, so that the rear bumper 10 has good structural strength and can play a role in protecting the components in the vehicle tail area.

[0040] In another example, the rear end of the energy absorption column 311 does not contact the rear bumper 10, that is, there is a collapse space between the rear end of the energy absorption column 311 and the rear bumper 10. When subjected to a collision impact, the rear bumper 10 can collapse inward, squeeze the collapse space, and contact the rear end of the energy absorption column 311. The cavity 312 makes the energy absorption column 311 prone to collapse and can play a buffering and energy absorption role.

[0041] Exemplarily, the energy absorption column 311 can be set as a cylindrical part, a frustum-shaped part, a prismatic part, or other irregular-shaped parts.

[0042] In one example, with reference to Figure 3 and Figure 4 , a functional groove 313 is provided on the main body 31. The functional groove 313 is used to reduce the weight of the main body 31 and is beneficial for the main body 31 to fit with the beam body 21, which is beneficial for improving the installation efficiency.

[0043] Exemplarily, the thickness of the main body 31 is 3 mm.

[0044] Exemplarily, the buffer member 30 is made of a PP (polypropylene) part or a part made of PP and GF (glass fiber). It is light in weight and low in mold development cost, reducing the production cost.

[0045] When the rear bumper 10 is collided, it has a tendency to deform toward the side close to the anti-collision beam 20. The energy-absorbing column 311 contacts the rear bumper 10 and can play a supporting role to absorb the collision energy, preventing the rear bumper 10 from continuing to collapse inward and squeezing other components, and can protect other components at the rear of the vehicle to prevent the components from being damaged or falling off.

[0046] As shown in Figure 5 , the anti-collision beam 20 includes a beam body 21. First flanges 22 and second flanges 23 are provided on both the upper and lower sides of the beam body 21.

[0047] Exemplarily, the first flanges 22 and the second flanges 23 are integrally formed with the beam body 21.

[0048] Exemplarily, the orthographic projection of the beam body 21 in the left-right direction is in a shape similar to a C, and the orthographic projection of the main body 31 in the left-right direction is in a shape similar to a C. As shown in Figure 2 , when the buffer member 30 is connected to the anti-collision beam 20, the front side of the main body 31 fits with the rear side of the anti-collision beam 20 to increase the contact area between the buffer member 30 and the anti-collision beam 20, which is beneficial for improving the connection quality.

[0049] With reference to Figure 3 and Figure 6The first mounting portion includes an extension piece 32 located on the upper and lower sides of the main body 31, and the extension piece 32 extends in the up-down direction.

The limiting piece 321 protrudes and extends toward the side away from the rear bumper 10 along the front-to-back direction. A latching tongue 322 is provided on the limiting piece 321. The latching tongue 322 is connected to the limiting piece 321 along the up-to-down direction, and a latching interval is provided between the latching tongue 322 and the extension piece 32 in the front-to-back direction. The latching tongue 322 cooperates with the extension piece 32 to realize the fixed latching of the second flange 23 in the front-to-back direction. The first mounting portion located on the upper and lower sides of the main body 31 can cooperate to realize the latching and fixing of the buffer 30 and the anti-collision beam 20 in the up-to-down direction, which is convenient for disassembly and assembly, and saves installation time.

[0054] When the buffer 30 is connected to the anti-collision beam 20, the buffer 30 and the anti-collision beam 20 are assembled in the left-right direction, so that the main body 31 fits with the beam body 21, the extension 32 contacts the front end of the first flange 22, and the limiter 321 contacts the upper end or lower end of the first flange 22. The buffer 30 is pushed relative to the anti-collision beam 20 in the left-right direction until the side of the second flange 23 close to the matching interval 24 is clamped between the clamping tongue 322 and the extension 32, which can realize the limit and fixation of the buffer 30 in the front-back direction and the up-down direction.
