[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0020] See also Figure 1 As shown, in this embodiment, a pedestrian protection device is provided, which is applied between the front bumper 1 and the cooling system. The front bumper 1 includes a front bumper skin, a front bumper side mounting bracket, and a front bumper middle mounting bracket. The front bumper middle mounting bracket has a certain rigidity, which can effectively ensure that the front bumper will not sink after installation.

[0021] In this embodiment, the pedestrian protection device includes a support member 2, one end of which is installed on the crossbeam of the radiator in the cooling system, and the other end of the support member 2 is in surface contact with the front bumper 1. The support member 2 is a long structure extending along the width direction of the vehicle to achieve the purpose of dispersing the impact force of the front bumper 1 on the upper legs of the pedestrian after the pedestrian is hit.

[0022] Furthermore, the support member 2 is made of a soft foam material, which can effectively absorb the energy of the collision after the pedestrian is hit, and further reduce the force on the pedestrian's upper legs.

[0023] By adding soft foam material between the front bumper and the cooling system, the contact area between the front bumper and the buffer structure is increased, so that the upper legs of pedestrians are effectively protected.

[0024] For details, see Figure 2-3 As shown, an X-direction support surface 3 is provided at the front end of the support member 2, and the X-direction support surface 3 is used to fit on the inner wall of the front bumper 1. After the pedestrian is hit, the deformation of the front bumper 1 can directly cause the deformation of the support member 2, and the support member 2 can achieve the purpose of dispersing the impact force of the front bumper 1 on the upper legs of the pedestrian after the pedestrian is hit.

[0025] Furthermore, a Z-direction support surface 5 is provided at the upper end of the support member 2, and the Z-direction support surface 5 is used to fit on the inner wall of the front bumper 1. The Z-direction support surface 5 is a long raised structure. The height of the Z-direction support surface 5 is greater than the height of the upper end surface of the X-direction support surface 3. The Z-direction support surface 5 increases the width of the support member 2 in the Z direction, thereby increasing the strength of the support member 2.

[0026] Furthermore, the support member 2 is provided with at least two installation points 4 corresponding to the cooling system. The installation point 4 is a groove structure. The support member 2 is provided with a fixing hole 41 at the bottom of the groove structure. The fixing hole 41 is used to insert screws to fix the support member 2 to the radiator beam of the cooling system, thereby facilitating the installation of the support member 2.

[0027] Furthermore, a groove 6 is provided in the middle of the support member 2, and the groove 6 divides the Z-direction support surface 5 into two left and right sections. When a pedestrian is hit and the impact position is located on the left and right sides of the support member 2, the support member 2 is more likely to deform, and the left and right sides of the front bumper 1 are more likely to deform, so that the force of the front bumper 1 reacting on the pedestrian is smaller, further dispersing the impact force on the pedestrian.

[0028] The working principle of the utility model is:

[0029] The pedestrian protection device can effectively disperse the impact force of the front bumper on the upper legs of pedestrians when the pedestrians are hit by vehicles, and reduce the force on the upper legs of pedestrians through buffering and energy absorption of the device, so as to effectively protect the upper legs of pedestrians from injury.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
