Problems solved by technology

In the former solution, since the water tank frame is designed as a sheet metal part, the overall weight is relatively heavy; and, in order to effectively support the calf support frame, the structure at the lower beam of the water tank also needs to be designed stronger or a separate bracket is designed to support it; the latter As the lower support structure of the calf is designed as a sheet metal part, the lightweight level is not high, and the structural design and layout also have more restrictions on the shape

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as Figure 1-6 As shown, an integrated pedestrian protection structure of the present invention includes a bumper skin 1, an energy-absorbing block 3 and an anti-collision beam 5. The bumper skin 1 is installed on the vehicle body, and the lower end integrates a calf support beam 1.1; the calf support Both ends of the beam 1.1 are fixedly connected to the upper anti-collision beam 5 through the side support bracket 4, and the energy-absorbing block 3 is fixedly arranged on the anti-collision beam 5.

[0022] The energy-absorbing block 3 absorbs the collision energy of the lower part of the lower leg, and the lower leg support beam 1.1 integrated with the bumper skin 1 and the side support bracket 4 on the anti-collision beam 5 absorb the collision energy of the lower part of the lower leg, including the side support bracket covered ...

Abstract

The invention relates to an integrated pedestrian protection structure. The structure comprises a bumper skin, an energy absorption block and an anti-collision beam, the bumper skin is installed on anautomobile body, and a shank supporting cross beam is integrated at the lower end of the bumper skin; and the two ends of the shank supporting cross beam are fixedly connected with the anti-collisionbeam on the upper portion through side supporting supports, and the energy absorption block is fixedly arranged on the anti-collision beam. When a pedestrian collides with the front end of the automobile, the upper portions of the shanks of the pedestrian make contact with the middle of the bumper skin, energy is transmitted to the energy absorption block, the energy absorption block deforms to absorb the energy and then transmits impact to the anti-collision beam, the lower portions of the shanks of the pedestrian make contact with the lower portion of the bumper skin, the shank supporting cross beam integrated on the lower portion of the bumper skin absorbs collision energy, and the energy is transmitted to the anti-collision beam through the side supporting supports. Light weight is achieved, and impact energy on the lower portions of shanks of pedestrians can be effectively absorbed.

Description

technical field [0001] The invention relates to the technical field of automobile pedestrian protection, in particular to an integrated pedestrian protection structure. Background technique [0002] Pedestrian protection has received more and more attention, and its technology has developed rapidly in recent years. Regulations and NCAP are constantly being updated, and the requirements are getting higher and higher. With extensive research investment, new structures and technologies are constantly emerging. In the traditional pedestrian protection technology, the lower support structure of the calf is generally transferred to the car body through the metal water tank lower beam, or the lower support structure of the lower leg is designed as a sheet metal part and welded to the front anti-collision beam. In the former solution, since the water tank frame is designed as a sheet metal part, the overall weight is relatively heavy; and, in order to effectively support the calf ...
