[0001] The utility model relates to the field of automobile electrical switches, in particular to a seat adjustment switch. Background Art

[0002] The seat adjustment switch is a critical safety feature in automobiles. While driving, the seat's position not only affects the driver's operability and comfort, but can also, to a certain extent, cause a sudden change in the seat's position due to a malfunctioning seat switch, directly impacting driver safety while driving. Therefore, having a stable seat adjustment switch is crucial for maintaining competitive advantage in the automotive industry. Seat adjustment is typically controlled and activated by four control buttons: forward, backward, left, and right.

[0031] Please refer to Figures 1 to 4.

[0032] The housing 1 is formed by a combination of a shell body and a cover plate. The shell body is provided with a cavity. An opening is formed on the end surface of one end of the shell body. The cavity of the shell body communicates with the outside world through the opening. The cover plate is provided at the opening of the shell body. A first microswitch 111 is provided in the shell body 1 and is fixedly connected to the cover plate. The first microswitch 111 is electrically connected to four first microswitches 111. The first microswitch 111 is electrically connected to two second microswitches 112. The two second microswitches 112 are arranged at intervals. The first microswitch 111 is electrically connected to a third microswitch 113. The four first microswitches 111 are arranged at intervals around the third microswitch 113. In this embodiment, preferably, two adjacent first microswitches 111 form a 90° right angle with the third microswitch 113 as the intersection point.

[0033] The end surface of one end of the limit seat 2 contacts the first micro switch 111.

The limit seat 2 is located in the cavity of the shell 1. The limit seat 2 is provided with a receiving cavity 21, which passes through the limit seat 2. Four extended edges 22 extend from the receiving cavity 21. The extended edges 22 are close to the end surface of the other end of the limit seat 2. The center axis of two adjacent extended edges 22 is located on the first micro switch 111, so that the boss 32 of the four-way slide 3 can slide in the horizontal or vertical direction when sliding. A mounting platform 23 is provided in the receiving cavity 21. The two sides of the mounting platform 23 are fixedly connected to the inner wall of the limit seat 2.

In this embodiment, the cross section of the special-shaped groove 421 is preferably triangular, and the ball 332 touches the bottom of the special-shaped groove 421. When the rotating shaft 4 is not rotated, the elastic member 333 touches the ball 332 and the top of the triangle of the special-shaped groove 421, so that the rotating shaft 4 maintains a certain angle on the boss 32. When the torque is turned, When the rotating shaft 4 rotates a certain angle, the ball 332 slides on one of the sides of the triangle in the special-shaped groove 421, pushing the ball 332 to squeeze the elastic member 333, so that the rotating shaft 4 generates a certain resistance when rotating. After the rotating shaft 4 stops rotating, the elastic member 333 pushes the ball 332 to slide on one of the sides of the triangle in the special-shaped groove 421. The ball 332 pushes the rotating shaft 4 to rotate while rolling until the ball 332 touches the top of the triangle in the special-shaped groove 421, thereby achieving the effect of rebound rotation of the rotating shaft 4.
