Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat welding, in particular to a welding device for a fixed armrest bracket of an automobile seat. Background Art

[0002] The car seat is an important part of the car, and it is also the part that comes into direct contact with the driver and passengers. It can provide a comfortable experience for the driver and passengers, and it is also related to the safety of the driver and passengers. The seat armrest is one of the important parts of the seat. It is located on both sides of the seat to protect the safety of the passengers. It can be rotated and folded for easy sitting. After sitting, it can be put down. At the same time, it can provide elbow support for the passengers to maintain a comfortable sitting posture. The armrest is installed on the seat fixed armrest bracket. It is a component with a circular shaft and a ratchet, which is welded on both sides of the backrest side panels. The ratchet can ensure that the armrest stops at a certain angle of rotation, and the circular shaft can ensure coaxial rotation around the center of the circle. The welding must be firm and the armrest must rotate smoothly, the ratchet does not get stuck, and the left and right bracket rotation axes are concentric. Therefore, the welding requirements for the fixed armrest bracket are still quite high.

[0003] In order to achieve this goal, it is necessary to have a positioning and clamping mechanism for the fixed handrail bracket to ensure the angle of the ratchet and the concentricity of the left and right bracket axes. It is easy to use and has good durability and reusability.

[0004] The existing positioning method is a round shaft plus a positioning pin and a positioning hole. The disadvantage of this mechanism is that the ratchet angle varies randomly. After the armrest is installed, the armrest cannot be guaranteed to be at the same angle, so that the elbow support is not on the same horizontal line, affecting the riding experience.

[0005] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research, and the technical solution to be introduced below is produced in this context. Utility Model Content
