[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] As an important part of the vehicle, the energy absorption device plays a vital role in the vehicle. The existing energy absorption device has a large gap between the front bumper and the anti-collision beam, which causes turbulence after the wind enters from the grille, resulting in insufficient air intake to the radiator; and when the vehicle collides with a pedestrian, the pedestrian's structural strength is relatively hard, which will cause more serious injuries to the pedestrian. At the same time, when the vehicle collides with an obstacle, it will impact the internal components of the vehicle, causing them to be damaged or fall off.
[0032] The utility model provides an energy absorbing device and a vehicle, aiming to solve the technical problem caused by the unreasonable structural design of the existing energy absorbing device.
[0033] See also Figure 1 and Figure 2 In one embodiment of the utility model, the energy absorbing device includes a front bumper 100, an anti-collision beam 200 and an energy absorbing block 300, the anti-collision beam 200 is provided with a first positioning unit, the energy absorbing block 300 is provided with a second positioning unit and a positioning surface 310, the second positioning unit is connected to the first positioning unit, the positioning surface 310 abuts against the anti-collision beam 200, and a wind guide space 320 is provided on the top of the energy absorbing block 300.
[0034] The technical solution of the utility model can avoid turbulence after the wind enters the vehicle from the grille by setting a wind guide space 320 on the top of the energy absorbing block 300, thereby increasing the air intake of the radiator, thereby improving the cooling performance, and also reducing the damage to pedestrians when the vehicle collides with them. In this embodiment, the energy absorbing block 300 is provided with a second positioning unit and a positioning surface 310, and the positioning surface 310 abuts against the anti-collision beam 200, that is, the positioning surface 310 and the anti-collision beam 200 are zero-touch fit, which can Figure 1 The energy absorbing block 300 is positioned in the Y direction; the second positioning unit is connected to the first positioning unit, which can be Figure 1The energy absorbing block 300 is positioned in the X and Z directions. By abutting the positioning surface 310 with the anti-collision beam 200 and connecting the second positioning unit with the first positioning unit, the energy absorbing block 300 can be positioned in the X, Y and Z directions to ensure that the energy absorbing block 300 is accurately positioned when installed on the anti-collision beam 200. In addition, when a vehicle collides with a pedestrian, the energy absorbing block 300 can provide a buffer to reduce the damage to the pedestrian when the pedestrian is hit. At the same time, the energy absorbing block 300 can also provide a buffer for the internal components of the vehicle (such as cameras, driving radars, parking radars, etc.) when the vehicle collides (for example, colliding with pillars, walls, etc.) to avoid the internal components of the vehicle from falling off or being damaged. A wind guide space 320 is provided at the top of the energy absorbing block 300. The setting of the wind guide space 320 can prevent turbulence from occurring after the wind enters the interior of the vehicle from the grille. Specifically, after the wind enters the interior of the vehicle from the grille, the wind guide space 320 can provide guidance for the wind, so as to guide the wind to the radiator, thereby preventing the wind from being turbulent in the gap between the front bumper 100 and the anti-collision beam 200, thereby increasing the air intake of the radiator; and the wind guide space 320 can also allow the wind to smoothly pass through the interior of the vehicle and then be discharged, thereby avoiding the generation of air pressure, thereby avoiding the increase of wind resistance when the vehicle is driving. The energy absorption device is applied to the field of vehicle technology.
[0035] It should be noted that the energy absorbing block 300 provides a buffer for the internal parts of the vehicle to prevent the internal parts of the vehicle from falling off or being damaged, and the effect is more significant when the vehicle collides at a low or medium speed. For example, when the vehicle collides with a wall or a pillar at a speed of 30 km / h, the energy absorbing block 300 can provide a buffer for the internal parts of the vehicle to prevent the internal parts of the vehicle from falling off or being damaged.
[0036] See also Figure 1 In one embodiment of the utility model, the first positioning unit includes a first positioning hole 210 and a second positioning hole 220 both opened in the anti-collision beam 200, and the second positioning unit includes a first positioning column 330 and a second positioning column 340 which are arranged in a one-to-one correspondence with the first positioning hole 210 and the second positioning hole 220. The first positioning column 330 and the first positioning hole 210 are interference-fitted in the first direction and the second direction of the front bumper 100, and the second positioning column 340 and the second positioning hole 220 are interference-fitted in the second direction of the front bumper 100.

Specifically, the first positioning column 330 and the first positioning hole 210 are interference fit in the first direction and the second direction of the front bumper 100, which can limit the position of the energy absorbing block 300 in the first direction and the second direction to ensure that the installation position of the energy absorbing block 300 is accurate. The second positioning column 340 and the second positioning hole 220 are interference fit in the second direction of the front bumper 100, which can limit the position of the energy absorbing block 300 in the second direction to ensure that the installation position of the energy absorbing block 300 is accurate.

Specifically, the two second positioning posts 340 located in the middle and the two first positioning posts 330 located on both sides both limit the position of the energy absorbing block 300 in the second direction, which can prevent the energy absorbing block 300 from tilting or sagging in the middle or at both ends. The first positioning post 330 cooperates with the first positioning hole 210 to limit the position of the energy absorbing block 300 in the first direction and the second direction, and the second positioning post 340 cooperates with the second positioning hole 220 to limit the position of the energy absorbing block 300 in the second direction, so as to ensure that the installation position of the energy absorbing block 300 is accurate.
