Description

Technical Field

[0001] This utility model relates to the field of automotive switch technology, and in particular to a rocker switch structure. Background Technology

[0002] Traditional automotive rocker switches are typically single-axis or dual-axis structures. Single-axis rocker switches, due to their low rotation axis, require a larger gap between the button and surrounding components, resulting in poor aesthetics. A gap of at least 0.65mm is generally needed; otherwise, interference with the components may occur when the switch is pressed. However, if a finger accidentally presses the center of the button, both left and right functions will not be activated simultaneously. Dual-axis structures can effectively reduce the matching gap to 0.5 to 0.6mm, but if a finger accidentally presses the center of the button, both left and right functions may be activated simultaneously, or one function may be randomly triggered, making it difficult to meet customer requirements during development. Therefore, a new rocker switch structure is needed to solve these problems simultaneously. Utility Model Content

[0003] The purpose of this utility model is to provide a rocker switch structure that solves the problems of large gap requirements for existing single-axis rocker switch components and the problem of abnormal function triggering when the double-axis rocker switch is pressed to the middle position of the button.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

The slide rail part and the sliding part are concentric and the slide rail part is located below the sliding part. A limiting part is fixedly provided on the outer side wall of the button base at a position below the sliding part. The slide rail part is slidably connected in the gap between the sliding part and the limiting part.

[0010] Preferably, in combination with the above scheme, the inner side walls of the shell are provided with a plurality of groups of reinforcing ribs at intervals, and the reinforcing ribs are fixedly connected with the lower arc surfaces of the slide rail parts.

[0011] Preferably, in combination with the above scheme, the reinforcing ribs are symmetrically arranged in parallel on the left and right sides of the slide rail parts and extend from top to bottom along the height direction.

[0023] like Figure 1 An existing single-axis rocker switch, when the left and right sides of the single-axis button 201 are pressed, rotates the switch around the single-axis rotation center 20a. The top posts on both sides of the button press down, causing the conductive particles of the rubber plate to contact the gold-plated disc on the circuit board, thus achieving conductivity. 20b represents 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. Because the distance 20d between the center of the single-axis rotation center 20a and the button surface is relatively far, the gap decreases significantly after rotation. This necessitates setting a relatively large gap 20c between the button and the accessory in the initial definition, resulting in a gap 20c of approximately 0.65mm, which is aesthetically unappealing. However, if a finger accidentally presses the middle of the button, both left and right functions will not be simultaneously activated.

[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 around the rotation center 30b under the action of the right push rod force; when the right side of the dual-axis button 301 is pressed, the button moves around the rotation center 30a under the action of the left push rod force. 30c represents the maximum outer contour movement trajectory of the button. This structure reduces the button's movement gap by increasing the button's rotation radius. The gap 30d between the button and the matching part 302 is approximately 0.58mm, which is relatively small. However, when a finger accidentally presses the middle position of the button, both left and right functions may be activated simultaneously, or a certain function may be randomly triggered, making it difficult to meet the needs of some customers.

[0025] And such Figures 3 to 7 The rocker switch structure shown includes a housing 1, a button base 2, a sliding part 21 with an arc structure and an upward opening that is fixedly provided on the outer side wall of the button base 2, a slide rail part 11 with an arc structure and an upward opening that is fixedly provided on the inner side wall of the housing 1, the slide rail part 11 and the sliding part 21 being concentric, the slide rail part 11 being located below the sliding part 21, and a limiting part 22 being fixedly provided on the outer side wall of the button base 2 at a position below the sliding part 21, the slide rail part 11 being slidably connected in the gap between the sliding part 21 and the limiting part 22.

[0026] To make the sliding structure more stable, the sliding part 21 and the limiting part 22 are symmetrically arranged on the two outer side walls of the button seat 2; the slide rail part 11 is symmetrically arranged on the two inner side walls of the outer shell 1.

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

[0028] To facilitate the insertion of the button base 2 into the housing 1 for assembly, the limiting part 22 is an inverted structure with a guide slope on its outer side.

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

[0030] To ensure the structural strength of the slide rail 11 and the outer shell 1, a number of reinforcing ribs 12 are provided at intervals on the inner sidewall of the outer shell 1, and the reinforcing ribs 12 are fixedly connected to the lower arc surface of the slide rail 11.

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

[0032] To ensure aesthetics, a button 5 is attached to the button base 2 via a snap-fit ​​connection, and a protective rubber plate 7 and a circuit board 8 are provided below the button base 2.

[0033] To illuminate the button characters with LED light, the button base 2 is provided with two sets of light guide grooves 23. A light guide part 71 is raised on the protective rubber plate 7 corresponding to the position of the light guide groove 23, and the light guide part 71 corresponds to the LED beads on the circuit board 8. This light guide part 71 is a hollow boss structure, allowing light to directly illuminate the button characters through the light guide part 71 and the light guide groove 23.

[0034] The principle of this utility model:

[0035] When the left or right side of button 5 is pressed, the sliding part 21 and the limiting part 22 will slide along the upper and lower arc surfaces of the slide rail part 11, respectively, so that the pressing boss 23 of 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 function.

[0036] The structure in this embodiment can raise the center of rotation 10a of the arc of the sliding part 21 and the slide rail part 11 to near the button surface, with a height of Figure 6The 10d in the design can be made level with the button surface, provided the structure allows. The design principle is to design the rotation center as close to the button surface as possible. This reduces the clearance requirement when the rocker switch button rotates. When the rotation center and the button surface are on the same horizontal plane, the clearance in the button's direction of movement is the minimum clearance for button movement. This results in a gradually increasing clearance 10c between the maximum rotational profile of the button and the corresponding component 6, effectively preventing interference with the component 6. Figure 6 10b in the figure represents the rotation trajectory of the button. The structure in this invention allows the gap between the button and accessory 6 to be as small as 0.5mm, resulting in a more aesthetically pleasing design and preventing accidental triggering of functions. It also prevents the button from being pressed down completely when pressed in the middle, thus avoiding the simultaneous activation of two functions.
