Titanium alloy metal injection molding automotive connecting rod guide seat MIM parts

Automobile link-type seat belt guide, which includes a connecting part with the body, a guide ring and a decorative shell. The connection part with the body is a long connecting rod. The upper end of the connecting rod has bolt mounting holes for connecting to the body. The lower end of the connecting rod is connected to the guide ring for installing the safety belt. The upper end of the connecting rod is provided with a limiting protrusion, which is used to cooperate with the corresponding recessed position on the vehicle body to limit the position of the guide member and prevent it from rotating.

In order to increase the strength of the connecting rod, there are flanges around the connecting rod and a large-area sinking platform punched in the middle.

In order to facilitate the reliable connection of the guide ring, a fixed piece is designed so that the guide ring is riveted to the lower end of the connecting rod through the fixed piece.

In addition, in order to ensure the beautiful appearance of the guide, the connecting rod is wrapped with a decorative shell, which can be formed by injection molding or other forms. A buffer boss is provided on the decorative shell to increase the distance between the external contact surface and the connecting rod to absorb energy, increase buffering and other protective functions.

By designing the connector into a connecting rod form, the distance between the guide ring and the fixed point of the seat belt is lengthened, thereby reducing the fixed point on the seat belt and meeting the regional requirements of existing national regulations for effective fixed points on the upper part of the seat belt. It can effectively ensure the safety of the occupants. At the same time, the structure is simple and the installation is relatively convenient.

This guide is mainly composed of three parts: connecting rod, guide ring and decorative shell. The guide ring is connected to the lower end of the connecting rod, and the decorative shell is wrapped around the connecting rod.

The connecting rod is a long stamped part with a bolt mounting hole on the upper end and a limit protrusion on the side. When installing the connecting rod, insert the limit protrusion into the corresponding opening position of the body before installing the bolt. This makes the connecting rod The rod will not rotate relative to the vehicle during movement, thereby ensuring the safety of the occupants. The lower end of the connecting rod is connected with a guide ring. The entire connecting rod is surrounded by fully-enclosed flanges, and there is a large-area sinking platform in the middle to ensure the strength requirements of this part. The guide ring is riveted to the lower end of the connecting rod through a triangular fixed piece to facilitate the installation of the seat belt. It not only meets the requirement that the guide ring does not rotate, but also meets the requirement that the guide component of the seat belt can be moved during use.

Since the connecting rod is a pure metal part, in order to further ensure the safety of the occupant's head, the part is wrapped with a decorative shell, and the main material used is rubber with good elasticity. There are many circular buffer bosses on the surface of the decorative shell, the purpose of which is to increase the distance between the external contact surface and the connecting rod to absorb energy, increase buffering and other protective functions.
