Description

Technical Field

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

[0002] The traditional slider slides in the interlayer formed by the shell and the bracket (surface-to-surface or surface-line matching), driving the micro switch to swing, triggering the micro switch contacts to contact and conduct; when the dimensions of the shell and the bracket are unstable and the gap is large, the switch operation has a large amount of movement, and when the gap is small, it will cause jamming or even stuck and unable to move, abnormal noise, resulting in poor use effect, affecting the normal use and quality stability of the product. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide a seat adjustment switch.

[0004] A seat adjustment switch includes a housing, a bracket and a PCB board are provided in the housing, a slider is slidably installed in the housing to drive the switch to open and close by sliding action, a mounting cavity for mounting the slider is formed between the bracket and the housing, the slider includes a base located in the mounting cavity, cantilevers are provided on both sides of the base extending from the center to two sliding directions, and a protruding limit point is provided at the end of the cantilever, the cantilever is in an upward state so that the limit point maintains an abutment state with the inner wall of the mounting cavity, and when the slider slides in the housing, the outer side of the cantilever abuts against the inner wall of the mounting cavity to limit the slider. The limit point of the cantilever structure abuts against the inner wall of the mounting cavity, effectively preventing the slider from loosening, deflecting or falling off during the sliding process, and the abutment of the limit point with the inner wall of the mounting cavity uses small faces or faces to automatically adjust the amount of movement, jamming, abnormal noise and other problems caused by the above dimensional instability, thereby improving the performance of the switch and extending the service life of the switch.

[0005] Preferably, a gap is defined between the housing and the bracket, the gap being located at the bottom of the mounting cavity. A stopper is provided on the lower end surface of the cantilever, the outer circumference of which is smaller than that of the cantilever, thereby forming a stopper step. The stopper step is used to prevent the cantilever from extending into the gap and becoming stuck there. By providing the stopper step, the cantilever cannot extend into the gap between the housing and the bracket, thereby effectively preventing the slider from becoming stuck due to excessive movement of the cantilever during operation, thereby ensuring normal operation of the switch.

[0006] Preferably, the limit point is located on the upper end surface of the cantilever, and the outer edge of the limit point is chamfered. This chamfered outer edge of the limit point effectively reduces the contact area with the inner wall of the mounting cavity, thereby reducing friction, reducing wear, and extending the service life of the connecting component. The chamfered design effectively absorbs and disperses the impact force generated by the slider during sliding, preventing sudden wear or damage caused by sharp edges, and ensuring smoother switch operation.

[0007] Furthermore, the stop point is circular in shape. This circular stop point evenly distributes force across the contact surface, reducing force concentration, thereby reducing wear and damage and extending the component's service life. The circular shape allows the slider to slide more smoothly, reducing friction, avoiding jamming, and improving the smoothness of the operating experience. The circular stop point effectively reduces dead angle contact with the inner wall of the mounting cavity, preventing jamming caused by corners and ensuring free movement of the slider.

[0008] Preferably, the connection between the two cantilevers is provided with an abutment portion that protrudes downward, and the bracket is provided with a plurality of protrusions for supporting the slider so that its bottom surface does not completely abut against the bracket, and the abutment portion abuts against the protrusion. The abutment portion and the protrusion on the bracket abut against each other, effectively providing additional support, ensuring the stability of the slider during operation, and reducing the left and right swing caused by the movement of the slider. Since the bottom surface of the slider does not completely abut against the bracket, the direct friction between the slider and the bracket is reduced, which reduces wear and extends the service life of the component. The design of the abutment portion and the protrusion enables the slider to maintain a certain degree of sliding freedom, promoting more flexible and smooth switching operation.

[0009] Furthermore, the raised portions are distributed around the base, and the abutment portions abut against the raised portions on either side of the slider. The placement of the raised portions around the base evenly distributes support force in all directions, ensuring stable support for the slider in all directions and enhancing the stability of the overall structure. The contact between the raised portions and the abutment portions on either side of the slider provides effective anti-tilt support, reducing the risk of the slider tilting or deflecting due to external forces and ensuring accuracy during operation.

[0010] Preferably, the housing is provided with an opening, and the end of the slider extends to the outside through the opening. The slider end extends to the outside through the opening, so that the user can conveniently perform manual operation, thereby improving the convenience of use.

[0011] Preferably, a microswitch is mounted on the PCB. The microswitch includes a lever, and a toggle channel is provided within the slider to accommodate the lever. The lever extends through the bracket into the toggle channel. The microswitch design enables the movement of the slider to directly trigger the switch, improving the device's response speed and control accuracy. The toggle channel within the slider effectively saves space, making the overall structure more compact and convenient for installation in limited installation spaces.

[0012] The beneficial effects of the present invention are as follows: the limit point of the cantilever structure abuts against the inner wall of the installation cavity, effectively preventing the slider from loosening, deflecting or falling off during the sliding process. The limit point abuts against the inner wall of the installation cavity, and uses small surfaces or surface points to automatically adjust the amount of movement, jamming, abnormal noise and other problems caused by the above dimensional instability, thereby improving the performance of the switch and extending the service life of the switch.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0021] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0022] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0023] like Figure 1-5 The figure shows an embodiment of a seat adjustment switch of the present invention, comprising a housing 1, a bracket 2 and a PCB board 4 being provided in the housing 1, a slider 3 being slidably installed in the housing 1 for driving the switch to open and close by a sliding action, a mounting cavity 11 for mounting the slider 3 being formed between the bracket 2 and the housing 1, the slider 3 comprising a base 31 located in the mounting cavity 11, cantilevers 32 extending from the center to two sliding directions are provided on both sides of the base 31, a protruding limit point 321 is provided at the end of the cantilever 32, the cantilever 32 is in an upward state so that the limit point 321 is kept in abutment with the inner wall of the mounting cavity 11, and when the slider 3 slides in the housing 1, the outer side of the cantilever 32 abuts against the inner wall of the mounting cavity 11 to limit the slider 3. The limit point 321 of the cantilever 32 structure abuts against the inner wall of the installation cavity 11, effectively preventing the slider 3 from loosening, deflecting or falling off during the sliding process. The limit point 321 abuts against the inner wall of the installation cavity 11, and uses small surfaces or surface points to automatically adjust the amount of movement, jamming, abnormal noise and other problems caused by the above dimensional instability, thereby improving the performance of the switch and extending the service life of the switch.

[0024] A gap 12 is defined between the housing 1 and the bracket 2, located at the bottom of the mounting cavity 11. A stopper 322 is provided on the lower end surface of the cantilever 32. The outer circumference of the stopper 322 is smaller than that of the cantilever 32, thereby forming a stopper step 323. The stopper step 323 prevents the cantilever 32 from extending into the gap 12 and becoming stuck therein. The stopper step 323 prevents the cantilever 32 from extending into the gap 12 between the housing 1 and the bracket 2, effectively preventing the slider 3 from becoming stuck due to excessive movement of the cantilever 32 during operation, thus ensuring proper operation of the switch.

[0025] The stop point 321 is located on the upper end surface of the cantilever 32, and its outer edge is rounded. This rounded edge effectively reduces the contact area with the inner wall of the mounting cavity 11, thereby reducing friction, reducing wear, and extending the service life of the connecting components. The rounded design effectively absorbs and disperses the impact force generated by the slider 3 during sliding, preventing sudden wear or damage caused by sharp edges and ensuring smoother switch operation.

[0026] The stop point 321 is circular in shape. The circular stop point 321 evenly distributes force across the contact surface, reducing force concentration, thereby reducing wear and damage and extending the life of the component. The circular shape allows the slider 3 to slide more smoothly, reducing friction, avoiding jamming, and improving the smoothness of the operating experience. The circular stop point 321 effectively reduces dead angle contact with the inner wall of the mounting cavity 11, preventing jamming caused by corners, and ensuring free movement of the slider 3.

[0027] The connection between the two cantilevers 32 is provided with an abutment portion 324 that protrudes downward. The bracket 2 is provided with a number of protrusions 21 for supporting the slider 3 so that its bottom surface does not completely abut against the bracket 2. The abutment portion 324 abuts against the protrusion 21. The abutment portion 324 abuts against the protrusion 21 on the bracket 2, effectively providing additional support, ensuring the stability of the slider 3 during operation, and reducing the left and right swing caused by the movement of the slider 3. Since the bottom surface of the slider 3 does not completely abut against the bracket 2, the direct friction between the slider 3 and the bracket 2 is reduced, reducing wear and extending the service life of the component. The design of the abutment portion 324 and the protrusion 21 enables the slider 3 to maintain a certain degree of sliding freedom, promoting more flexible and smooth switching operations.

[0028] The raised portions 21 are distributed around the base 31, and the abutment portions 324 abut against the raised portions 21 on both sides of the slider 3. The raised portions 21 distributed around the base 31 evenly distribute support force in all directions, ensuring stable support for the slider 3 in all directions and enhancing the stability of the overall structure. The contact between the raised portions 21 on both sides of the slider 3 and the abutment portions 324 provides effective anti-tilt support, reducing the risk of slider 3 tilting or shifting due to external forces and ensuring accuracy during operation.

[0029] The housing 1 is provided with an opening 13, and the end of the slider 3 extends to the outside through the opening 13. The end of the slider 3 extends to the outside through the opening 13, so that the user can conveniently perform manual operation, thereby improving the convenience of use.

[0030] A microswitch 41 is mounted on the PCB 4. This microswitch 41 includes a lever. A toggle channel 33 is provided within the slider 3 to accommodate the lever. The lever extends through the bracket 2 and into the toggle channel 33. The design of the microswitch 41 allows movement of the slider 3 to directly trigger the switch, improving the device's response speed and control accuracy. The provision of the toggle channel 33 within the slider 3 effectively saves space, making the overall structure more compact and facilitating placement within limited installation spaces.

Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
