Embodiment Construction

[0029] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details.

[0030] In the existing collapse energy-absorbing structure, in order to make the structure easy to break, the width of the break is required to be set very narrow, otherwise it will be difficult to break; however, if the width of the break is too narrow, it will lead to the There are too few circuits in the car, which will affect the function and circuit performance of the car.

[0031] Therefore, in order to not only protect the safety of the occupants in the car, but also ensure the function and circuit performance of the car, the present invention provides a kind of protrusion collapse energy-absorbing structure, which is passed between the circuit board, the instrument panel and the rear cover Th...

Abstract

The invention provides a protrusion crumpling energy absorption structure which comprises a circuit board, a button device, an instrument board and a rear cover. A bottomless groove is formed in the instrument board, the bottomless groove is fixedly connected with the circuit board, and the button device is fixed at the position, corresponding to the bottomless groove, of the circuit board. A first supporting wall is arranged between the circuit board and the instrument board, and a second supporting wall is arranged between the circuit board and the rear cover. Moreover, the distance between the first supporting wall and the bottomless groove is larger than the distance between the second supporting wall and the bottomless groove, and the gap between the second supporting wall and the button device is a safety crack position. According to the protrusion crumpling energy absorption structure, the problem that the crumpling energy absorption structure can not be completely cracked under the conditions that the crumpling energy absorbing structure is borne by the same external force and the set width of the crumpling energy absorption structure is large is solved.

Description

technical field [0001] The invention relates to the technical field of structural safety, and more specifically, to a protrusion collapse energy-absorbing structure. Background technique [0002] With the continuous improvement of the utilization rate of automobiles, the occurrence of road traffic accidents has become more frequent. When safety accidents are unavoidable, as the last barrier for drivers and passengers, the structure and strength of the car body play a vital role in safety protection in the absorption and transmission of collision energy. [0003] In order to prevent the vehicle from causing excessive impact on the occupants of the car during the collision process and causing injuries to the occupants, it is necessary to set a button on the surface of the car dashboard to cut off the circuit in response to the impact and a corresponding collapse energy-absorbing structure . The collapse energy-absorbing structure is used to provide a certain buffer for sudde...
