Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a seat adjustment switch with a rubber feel. Background Technology

[0002] Currently, most mid-to-high-end cars are equipped with power seats. The power adjustment function of the power seats is controlled by the seat adjustment switch. This switch works in conjunction with the seat adjustment device to adjust the seat's fore-and-aft position, the backrest tilt angle, the headrest height, and the lumbar support height and depth. By adjusting the relative position of the seat and the car body through the switch, the user's body posture can be adjusted until a more comfortable state is achieved.

[0003] Currently, mainstream car manufacturers use toggle switches for seat adjustment. For example, Chinese utility model patent application number CN201721647285.3 discloses a vehicle seat switch assembly and a vehicle. The vehicle seat switch assembly includes an adjustment knob, a mounting base with a cavity, a circuit board housed in the cavity, and a toggle switch connected to the circuit board. The toggle switch protrudes from the mounting base and is connected to the adjustment knob. The circuit board is electrically connected to a drive motor for adjusting the seat. The user drives the toggle switch through the adjustment knob, thereby conducting the circuit. The drive motor can control the adjustment of the seat height and fore-aft position, etc.

[0004] However, in actual use, the seat adjustment switch uses a toggle switch. Since the toggle switch itself is noisy, it is difficult to meet the customer's noise requirements. Therefore, it is necessary to improve the existing car seat adjustment switch. Utility Model Content

[0005] The purpose of this invention is to provide a seat adjustment switch with a rubber feel. This invention has the advantages of lower operating noise, softer feel and lower cost.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber-feel seat adjustment switch, comprising a housing, a base plate installed at the bottom of the housing, a circuit board disposed within the base plate, conductive rubber covering the circuit board, a support for fixing the conductive rubber, a slider slidably disposed on the housing, a rocker arm linked with the slider, and a pressure block disposed between the rocker arm and the conductive rubber. The conductive rubber is provided with at least two sets of trigger buttons protruding away from the circuit board. The trigger buttons abut against the pressure block. A floating gap is provided between the trigger buttons and the circuit board. The slider moves horizontally and drives the pressure block downward through the rocker arm, so that the corresponding trigger buttons on the conductive rubber have a first state of abutting against the circuit board to form an electrical conduction state and a second state of disengaging from the circuit board and breaking the electrical connection.

[0007] By adopting the above technical solution, after the slider moves horizontally, the swing arm swings, causing the pressure block to press down on the conductive rubber, so that the trigger button on the conductive rubber abuts against the dome switch on the circuit board to activate the function. The feel, operating force, and stroke of the conductive rubber can all be adjusted according to customer needs. At the same time, the operating noise is low. In addition, compared with toggle switches, this structure has a softer feel and lower cost.

[0008] The present invention is further configured such that the upper end of the inner shell is provided with a first pressing protrusion for pressing against the upper end of the support, the lower end of the support is provided with a second pressing protrusion for pressing against the upper end of the conductive rubber, the base plate is provided with a support protrusion for abutting against the bottom of the circuit board, and the circuit board is sandwiched between the conductive rubber and the base plate.

[0011] By adopting the above technical solution, the circuit board and conductive rubber can be positioned to ensure the stability of their installation structure.

[0012] The present invention is further configured such that a guide hole is provided at the upper end of the outer shell, the lower part of the slider is disposed between the outer shell and the support, the upper part of the slider passes through the guide hole and slides with the guide hole, the slider is also provided with at least one guide groove whose extension direction is parallel to the extension direction of the guide hole, and the support is provided with a guide block that extends into the guide groove and slides with the guide groove.

[0013] By adopting the above technical solution, the stable directional sliding of the slider (such as left and right sliding) can be guaranteed.

[0014] The present invention is further configured such that the portion of the slider located inside the outer shell is provided with multiple fixed support points, and the upper and lower ends of the fixed support points respectively abut against the inner wall of the outer shell and the upper end of the support.

[0015] By adopting the above technical solution, the slider can be tightly fitted inside the housing and slide smoothly.

[0016] The present invention is further configured such that the portion of the slider located inside the outer shell is provided with a plurality of elastic arms, the end of the elastic arm is provided with a floating fulcrum, and the elastic arm is subjected to the squeezing action of the outer shell, so that the floating fulcrum is squeezed and engaged with the upper end of the outer shell.

[0019] By adopting the above technical solution, the contact area between the slider and the outer shell, and between the slider and the support can be reduced, thereby reducing surface energy and reducing abnormal noise caused by friction.

[0020] The present invention is further configured such that the swing arm includes a spherical body located in the middle, a plurality of driving parts disposed around the spherical body, and a linkage rod disposed at the upper end of the spherical body.

[0027] Example: As attached Figures 1-7The illustrated rubber-feel seat adjustment switch includes a housing 1, a base plate 2 mounted on the bottom of the housing 1, a circuit board 3 disposed within the base plate 2, conductive rubber 4 covering the circuit board 3, a support 5 for fixing the conductive rubber 4, a slider 6 slidably disposed on the housing 1, a rocker arm 7 linked with the slider 6, and a pressure block 8 disposed between the rocker arm 7 and the conductive rubber 4. The conductive rubber 4 is provided with at least two sets of trigger buttons 9 protruding away from the circuit board 3, with two trigger buttons 9 forming a group. One pressure block 8 corresponds to two trigger buttons 9. The trigger buttons abut against the pressure block 8. A floating gap 10 is provided between the trigger buttons 9 and the circuit board 3. The slider 6 moves horizontally and drives the pressure block 8 downward through the rocker arm 7, so that the corresponding trigger button 9 on the conductive rubber 4 has a first state of being electrically connected by abutting against the circuit board 3 and a second state of being disconnected from the circuit board 3. After the slider 6 is moved horizontally, the rocker arm 7 swings, causing the pressure block 8 to press down on the conductive rubber 4, so that the trigger button 9 on the conductive rubber 4 abuts against the dome switch on the circuit board 3 to activate the function. The feel, operating force, and stroke of the conductive rubber 4 can be adjusted according to customer needs. At the same time, the operating noise is low. In addition, compared with the toggle switch, this structure has a softer feel and lower cost.

[0028] As attached Figure 1 As shown, the upper end of the outer casing 1 is provided with a first pressing protrusion 11 for pressing against the upper end of the support 5, and the lower end of the support 5 is provided with a second pressing protrusion 12 for pressing against the upper end of the conductive rubber 4. The base plate 2 is provided with a support protrusion 13 for abutting against the bottom of the circuit board 3, and the circuit board 3 is sandwiched between the conductive rubber 4 and the base plate 2. The support 5, conductive rubber 4, and circuit board 3 can be fixed simply by connecting the base plate 2 and the outer casing 1 together with fasteners, such as screws, making installation very convenient.

[0029] As attached Figure 1 and attached Figure 2 As shown, the base plate 2 is provided with a first positioning rod 14. The circuit board 3 and the conductive rubber 4 are respectively provided with a first positioning hole 15 and a second positioning hole 16 for the insertion of the first positioning rod 14.

The circuit board 3 and the conductive rubber 4 can be positioned to ensure the stability of their installation structure.

[0030] As attached Figure 1 and attached Figure 2As shown, the upper end of the outer shell 1 has a guide hole 22. The lower part of the slider 6 is disposed between the outer shell 1 and the support 5. The upper part of the slider 6 passes through the guide hole 22 and slides in cooperation with the guide hole 22. The slider 6 also has at least one guide groove 23 whose extending direction is parallel to the extending direction of the guide hole 22. The support 5 has a guide block 24 that extends into the guide groove 23 and slides in cooperation with the guide groove 23.

The spherical body 29, the driving parts 30, and the linkage rod 31 are an integral structure. The support 5 is provided with a rotating groove 32 that matches the shape of the spherical body 29. The lower end of the slider 6 is provided with a flared groove 33 that is smaller in the inside and larger in the outside. In this embodiment, the flared groove 33 is a combination structure of a cylindrical groove at the upper end and a flared groove at the lower end. The linkage rod 31 extends into the flared groove 33, and the upper end of the linkage rod 31 is provided with a spherical linkage part 34 that forms a rolling engagement with the flared groove 33. The lower end of the driving part 30 abuts against the upper end of the corresponding pressure block 8. This design can realize the linkage between the slider 6 and the swing arm 7, that is, when the slider 6 slides left and right, the swing arm 7 swings around the rotating groove 32.

[0035] As attached Figure 2 As shown, the support 5 is provided with multiple vertically extending guide grooves 35, and the pressure block 8 is vertically slidably disposed in the corresponding guide groove 35. When the swing rod 7 swings, it can drive the corresponding support 5 to move downward along the guide groove 35, thereby pressing down the corresponding trigger button 9 on the conductive rubber 4 to trigger the function. The structure is stable and reliable.
