In the present invention, the longitudinal direction of the vehicle is defined as the front-rear direction, the height direction of the vehicle is defined as the up-down direction, and the width direction of the vehicle is defined as the left-right direction, and the directions of the respective members in the steering wheel assembly of the present invention are defined in correspondence with the directions of the vehicle. Specifically, the top wall of the hood is defined based on the orientation in which the hood is installed in the vehicle, that is, the top wall of the hood is a wall located at the upper portion of the hood in the up-down direction of the vehicle when the hood is installed in the vehicle, and the orientations of the other members are defined in a similar manner, for example, the bottom surface of the side wall is a surface of the side wall located at the lower portion of the side wall in the up-down direction of the vehicle, and the bottom surface of the accommodating portion is a surface of the accommodating portion located at the lower portion of the accommodating portion in the up-down direction of the vehicle.
As shown in fig. 1, steering wheel assembly 10 also includes a light-emitting sign that is capable of emitting light when energized. The illuminated sign includes a light emitting member 210 and a printed circuit board 220, the light emitting member 210 being connected to the printed circuit board 220 via an electrical connector 230 (shown in fig. 2), the electrical connector 230 being a wire harness or a flexible circuit board. Specifically, the light emitting member 210 is disposed at the top wall 110 of the cover cap 100, for example, at a substantially central position of the top wall 110, and the light emitting member 210 may be disposed on an inner side surface of the top wall 110, i.e., an upper side surface of the top wall 110 shown in fig. 1, or an outer side surface, i.e., a lower side surface of the top wall 110 shown in fig. 1. The printed circuit board 220 is disposed in a receiving portion 1201 on the side wall 120 of the cover 100, the receiving portion 1201 being formed by a portion of the side wall 120 being recessed toward the outside of the cover 100. In other words, in the cover 100 shown in fig. 1, a portion of the side wall 120 is recessed substantially upwards (towards the outside of the cover), so that at the portion of the side wall 120 where the recess occurs a new space is expanded towards the outside of the cover with respect to the remaining portion, which new space is dedicated to accommodating a printed circuit board, which therefore does not occupy the space that would have been designed to accommodate an air bag.
Therefore, in the present invention, the printed circuit board is provided in the housing portion formed by recessing a portion of the sidewall of the cover toward the outside of the cover, the original inner space of the cover can be completely and entirely used for disposing the airbag, and when the airbag of the airbag is deployed, the printed circuit board is located in the housing portion so as not to be impacted by the airbag since it is not provided on the front side of the impact caused by the deployment of the airbag. Therefore, the printed circuit board provided by the utility model has better working performance and longer service life.
With continued reference to fig. 1. As shown in fig. 1, a fixing member for fixing the printed circuit board 220 is formed inside the accommodating part 1201.
