Description

Technical Field

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

[0002] Car seat adjustment control switches are used to control the forward, backward, and upward / downward movement of the seat, typically implemented using four control switches on a circuit board. There are currently two implementations for activating these four control switches. One uses two independent dials, such as Chinese patent application No. 201120161727.X, titled "Car Seat Adjustment Switch," which discloses a two-dial control structure. This structure offers a simple single switch, but the two dials take up a lot of space. Another approach uses a rocker-type four-way control structure, requiring only a single dial. However, this switch has a complex internal structure, making assembly inconvenient and manufacturing costly. This rocker-type switch structure is described in Chinese patent application No. 201910899041.1, titled "Car Seat Adjustment Rocker Switch." Both control switch structures have advantages and disadvantages. Therefore, it is necessary to develop a single-dial switch structure while reducing the number of parts and manufacturing costs. Utility Model Content

[0003] The utility model aims to provide a car seat adjustment control switch, which solves the problem that the existing four-way adjustment switch of the seat has many parts and a complicated structure.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows: a car seat adjustment control switch, comprising a housing, a base, and a circuit board disposed in the base; the circuit board is provided with four micro switches, the four micro switches being distributed in four directions; a four-way rotating rod is disposed in the housing, the four-way rotating rod comprising a universal ball mated with a spherical surface of the housing, four pressure rods disposed on the universal ball and respectively mated with the four micro switches for conduction; a swing rod for driving the universal ball to swing is disposed above the universal ball; a slider for driving the swing rod to swing is disposed above the swing rod; a dial button is fixedly disposed on the slider;

[0005] The slider is provided with a waist-shaped hole and a cylindrical hole matching the top of the rocker arm, and the shell is provided with a rotating pin matching the waist-shaped hole. The slider can move horizontally along the length direction of the waist-shaped hole and can also rotate around the rotating pin.

[0006] In order to avoid jamming, the top of the rocker arm that matches the cylindrical hole is a spherical matching end.

[0007] In order to facilitate the assembly and connection between the dial button and the slider, a plug-in piece is integrally formed on the slider, and the dial button is plugged into the plug-in piece.

[0008] Furthermore, a group of vertical limiting ribs are provided on the plug-in piece, a group of limiting grooves cooperating with the vertical limiting ribs are provided on the inner wall of the plug-in hole of the button, buckles are symmetrically provided on both sides of the plug-in piece, and a buckle hole cooperating with the buckle is provided on the button.

[0009] The beneficial effects of the present invention are as follows: the present invention can realize four-way adjustment by cooperating with the four-way rotating rod and the slider, combined with the micro switch below. It has a simple structure, is easy to assemble, and is reliable. In addition, the structure takes up little space, can greatly reduce the thickness of the switch body, and is convenient for arrangement in the vehicle. The cooperating structure of the waist-shaped hole of the slider and the rotating shaft can realize the movement of the slider along the length direction of the waist-shaped hole, and can also swing around the rotating shaft, thereby controlling the four-way rotating rod to rotate in four directions, so that different micro switches are pressed and turned on. The assembly of the slider and the dial button adopts plug-in cooperation, which is simple and convenient.

[0010] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Examples, such as Figures 1 to 5 As shown, a car seat adjustment control switch includes a housing 1, a base 2 and a cover 8 mounted on the housing 1, a circuit board 3 arranged in the base 2, and a waterproof rubber 9 covering the circuit board 3.

[0017] To achieve the four-way adjustment function of the single-touch dial, a four-way rotating rod 5 is installed within the housing 1. The four-way rotating rod 5 includes a universal ball 51 that mates with the spherical surface of the housing 1. The inner wall of the housing 1 is provided with a spherical surface that mates with the universal ball 51. This structure allows the four-way rotating rod 5 to rotate in any direction within the housing 1. The universal ball 51 is equipped with four pressure rods 52, which are arranged in a cross shape. Below each pressure rod 52, four micro switches 4 are installed on the circuit board 3. Rotation of the universal ball 51 controls the downward pressure of different pressure rods 52, thereby triggering different micro switches 4 to conduct.

[0018] In order to control the four-way rotating rod 5 to rotate in four directions to press the micro switch 4, a rocker 53 is provided above the universal ball 51 to drive the universal ball 51 to swing, and a slider 6 is provided above the rocker 53 to drive the rocker 53 to swing, and a dial button 7 is fixed on the slider 6.

[0019] Specifically, the slider 6 is an overall rectangular structure, equipped with a waist-shaped hole 61 and a cylindrical hole 62 that mates with the top of the rocker 53. The housing 1 is provided with a pivot pin 11 that mates with the waist-shaped hole 61. The diameter of the pivot pin 11 matches the width of the waist-shaped hole 61, allowing the slider 6 to move horizontally along the length of the waist-shaped hole 61 while also rotating about the pivot pin 11. When the slider 6 moves horizontally, the rocker 53 swings back and forth in the direction of the slider 6's movement, controlling the forward and backward rotation of the universal ball 51, thereby pressurizing and turning on the microswitch 4 located below in the forward and backward direction. When the slider 6 rotates about the pivot pin 11, the rocker 53 is controlled to swing left and right, causing the universal ball 51 to swing back and forth, thereby pressurizing and turning on the microswitch 4 located below in the left and right directions.

[0020] In order to ensure that the movement of the slider 6 can smoothly drive the swing rod 53 to swing and avoid jamming, the top of the swing rod 53 that cooperates with the cylindrical hole 62 is a spherical matching end 531.

[0021] To facilitate assembly of the dial button 7 and the slider 6, a plug-in plate 63 is integrally formed on the slider 6, and the dial button 7 is inserted into the plug-in plate 63. The plug-in plate 63 is provided with a set of vertical limiting ribs 64, and the inner wall of the insertion hole of the dial button 7 is provided with a set of limiting grooves (not shown in the figure) that cooperate with the vertical limiting ribs 64. Buckles 65 are symmetrically provided on both sides of the plug-in plate 63, and the dial button 7 is provided with a locking hole 71 that cooperates with the buckle 65. The dial button 7 is inserted into the plug-in plate 63 along the vertical limiting ribs 64. When the plug-in is in place, the buckle 65 snaps into the locking hole 71, completing the assembly. The assembly is simple and convenient.

Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
