Description

Technical Field

[0001] The invention relates to the technical field of automobile switches, and in particular to a rocker switch structure. Background Art

[0002] Traditional car rocker switches are usually single-axis or dual-axis structures. Due to the low rotation axis, the single-axis rocker switch requires a large gap between the button and the surrounding matching parts, and the aesthetics are not high. Generally, at least 0.65mm gap is required, otherwise there will be interference with the matching parts when the switch is pressed, but when the finger presses the middle of the button by mistake, the left and right functions will not be turned on at the same time; while the dual-axis structure can effectively reduce the matching gap to 0.5 to 0.6mm, but when the finger presses the middle of the button by mistake, the left and right functions may be turned on at the same time, or a certain function may be randomly triggered, making it difficult to meet customer needs during the development process. Therefore, it is necessary to invent a new rocker switch structure to solve the above problems at the same time. Summary of the invention

[0003] The purpose of the present invention is to provide a rocker switch structure, which solves the problem that the existing single-axis rocker switch has a large gap requirement for accessories and that the double-axis rocker is prone to abnormal function triggering when the button is pressed to the middle position.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0006] Preferably, in combination with the above solution, the sliding portion and the limiting portion are symmetrically arranged on two outer side walls of the button seat; and the slide rail portion is symmetrically arranged on two inner side walls of the shell.

[0023] like Figure 1 An existing single-axis rocker switch, when the left and right sides of the single-axis button 201 are pressed, the switch rotates with the single-axis rotation center 20a, and the top columns on both sides of the button are pressed down, so that the conductive particles of the rubber plate contact with the gold-plated disk on the circuit board to achieve conduction. 20b is the maximum outer contour movement trajectory of the button. During the pressing process, the movement gap between the button and the accessory 202 becomes smaller and smaller. Since the center of the single-axis rotation center 20a is far away from the button surface by distance 20d, the gap is reduced more after rotation, resulting in the need to set the gap between the button and the accessory to be larger in the early definition, and the gap 20c is about 0.65mm, which makes the appearance not high. However, when the finger accidentally presses the middle of the button, the left and right functions will not be turned on at the same time.

[0024] like Figure 2 An existing dual-axis rocker switch, when the left side of the dual-axis button 301 is pressed, the button moves with the rotation center 30b as the rotation axis under the action of the right push rod force; when the right side of the dual-axis button 301 is pressed, the button moves with the rotation center 30a as the rotation axis under the action of the left push rod force. 30c is the maximum outer contour motion trajectory of the button. This structure reduces the movement gap of the button by increasing the rotation radius of the button. The gap 30d between the button and the accessory 302 is about 0.58mm, which is a small gap. However, when the finger accidentally presses the middle position of the button, the left and right functions may be pressed down and turned on at the same time, or a certain function may be randomly triggered, making it difficult to meet the needs of some customers.

[0025] And as Figures 3 to 7 A rocker switch structure shown in the figure includes a shell 1, a button seat 2, a sliding portion 21 with an arc structure and an opening facing upward protruding and fixed on the outer side wall of the button seat 2, a slide rail portion 11 with an arc structure and an opening facing upward protruding and fixed on the inner side wall of the shell 1, the slide rail portion 11 is cocentric with the sliding portion 21, and the slide rail portion 11 is arranged below the sliding portion 21, and a limiting portion 22 is protruding and fixed on the outer side wall of the button seat 2 at a position below the sliding portion 21, and the slide rail portion 11 is slidably connected in the gap between the sliding portion 21 and the limiting portion 22.

[0026] In order to make the sliding structure more stable, the sliding portion 21 and the limiting portion 22 are symmetrically arranged on the two outer side walls of the button base 2 ; and the slide rail portion 11 is symmetrically arranged on the two inner side walls of the housing 1 .

[0027] In order to reduce the sliding friction between the sliding part 21 and the slide rail part 11 , a plurality of sliding bosses 211 with arc structures are arranged at intervals on the lower arc surface of the sliding part 21 . The sliding bosses 211 are slidably connected to the upper arc surface of the slide rail part 11 .

[0028] In order to facilitate the insertion of the button seat 2 into the housing 1 for assembly, the limiting portion 22 is an inverted structure, and a guiding inclined surface is arranged on the outer side thereof.

[0029] In order to facilitate the conduction function by pressing the push rod structure when the left and right sides of the button are pressed, the left and right sides of the button seat 2 are raised with pressing bosses 23, and a push rod 3 is provided below the pressing boss 23. The lower end of the push rod 3 cooperates with the micro switch 4 on the circuit board.

[0030] In order to ensure the structural strength of the slide rail portion 11 and the housing 1 , a plurality of groups of reinforcing ribs 12 are arranged at intervals on the inner side wall of the housing 1 . The reinforcing ribs 12 are fixedly connected to the lower arc surface of the slide rail portion 11 .

[0031] In order to ensure balanced force, the reinforcing ribs 12 are symmetrically arranged on the left and right sides of the slide rail portion 11 and extend from top to bottom along the height direction.

[0032] In order to ensure aesthetics, a button 5 is connected to the button seat 2 by snap-fitting, and a protective rubber plate 7 and a circuit board 8 are arranged below the button seat 2 .

[0033] In order to illuminate the button characters through LED lights, two sets of light guide grooves 23 are provided in the button seat 2, and a light guide portion 71 is provided at a position corresponding to the light guide grooves 23 on the protective rubber plate 7, and the light guide portion 71 is provided corresponding to the LED lamp beads on the circuit board 8. The light guide portion 71 is a hollow boss structure, and the light can directly illuminate the button 5 characters through the light guide portion 71 and the light guide grooves 23.

[0034] Principle of the present invention:

[0035] When the left or right side of the button 5 is pressed, the sliding portion 21 and the limiting portion 22 will slide along the upper arc surface and the lower arc surface of the slide rail portion 11 respectively, so that the pressing boss 23 of the button 5 presses down the push rod 3, and the push rod presses down the micro switch 4 on the circuit board to realize the conduction of the function.

[0036] The structure in this embodiment can raise the rotation center 10a of the arc of the sliding part 21 and the rail part 11 to a height close to the button surface. Figure 6 10d in the figure can also be made to be at the same level as the button surface when the structure allows. The design principle is to design the rotation center as close to the button surface as possible. In this case, the clearance requirement for the rocker switch button when rotating will be smaller. When the rotation center and the button surface are at the same level, the clearance in the button movement direction is the minimum clearance for the button movement. In this way, the clearance 10c between the maximum contour of the button rotation and the accessory 6 will become larger and larger, which can effectively avoid interference with the accessory 6. Figure 610b is the rotation track of the button. Through the structure of the present invention, the gap between the button and the accessory 6 can be reduced to 0.5 mm or even smaller, which is more aesthetically pleasing and can also avoid false triggering of functions. When pressing the middle of the button, it cannot be pressed down, and two functions will not be turned on at the same time.
