Description

Technical Field

[0001] The utility model belongs to the field of automobile seat operation, and particularly relates to a support structure for a seat adjustment switch. Background Art

[0002] At present, for the electric seat adjustment switch on the market, the seat is usually adjusted forward and backward by pushing the switch forward and backward. Before pushing the switch forward and backward, the switch needs to be pressed downward to enter the adjustment state of the switch, so as to prevent the driver from accidentally touching the switch during normal driving and causing the seat to move and affect driving. A spring is arranged in the support structure for pressing the switch, which not only plays a supporting role but also enables the switch to have an upward reset function to prevent the driver from forgetting to switch the adjustment state of the switch. However, during vehicle driving, the spring and the switch in the support structure are prone to shaking, resulting in noise generated by the spring movement, and noise is also generated when the spring is compressed or reset under force, affecting the driver's use experience. Summary of the Invention

[0003] Objective of the utility model: In order to overcome the defects of the prior art, the utility model provides a support structure for a seat adjustment switch, which solves the problem of noise generated by the shaking of the support structure during the driving of an automobile with a seat adjustment switch.

[0004] Technical solution of the utility model: A support structure for a seat adjustment switch includes a mounting seat, an adjustment switch, and a trigger fixedly arranged on the mounting seat. A main swing member and a sub-swing member that can swing in the same direction relative to the mounting seat are rotatably arranged on the mounting seat. Both the main swing member and the sub-swing member include a reset structure. The reset structure includes a counterbore for placing a silicone rubber member, and a support member for supporting the adjustment switch is arranged in each counterbore. After being pressed, the adjustment switch can contact and drive the main swing member to swing. The bottom of the support member contacts the silicone rubber member, and the support member moves in the pressing direction in the counterbore and presses the silicone rubber member. The bottom of the main swing member includes a contact head that can swing and contact the control contact of the trigger.

[0005] By adopting the above technical solution, a silicone rubber member is arranged at the bottom of the support member below the adjustment switch. The support member can press the silicone rubber member to deform, so as to realize that the adjustment switch contacts and controls the main swing member to swing, so that the contact head contacts the control contact of the trigger to realize seat adjustment. After the pressing force is lost, the support member can be reset under the elastic force of the silicone rubber member. Compared with a spring, the silicone rubber member is soft and elastic as a whole, and no noise is generated during the deformation and reset process, realizing the reset function of the adjustment switch, and no noise is generated during the operation process. Even if the vehicle drives and causes the switch, the support member, and the silicone rubber member to shake, no noise is generated, making the driver have a good use experience.

[0006] The utility model is further configured as follows: the bottom of the regulating switch includes a slide groove for a supporting member to slide and a positioning hole for positioning another supporting member, and the outer wall of the main swinging member includes a spherical surface protruding outward and extending into the positioning hole.

[0007] With the above further arrangement, the top of the support member of the reset structure is supported on the bottom of the adjustment switch, and while achieving the supporting effect, the spherical surface of the main swing member in a spherical structure can be extended into the positioning hole, which can ensure that the spherical surface can be pushed by the positioning hole, thereby ensuring the swing of the main swing member and thus ensuring the seat adjustment, and the slide groove can allow the support member to slide upward, reducing the connection structure between the adjustment switch and the auxiliary swing member, thereby avoiding the influence of the shaking of the auxiliary swing member on the adjustment switch, and further enhancing the control accuracy.

[0008] The utility model is further configured as follows: each support member includes a protrusion located on the side wall and a sink located below the protrusion, and the sink and the bottom of the support member form a locking block;

[0009] The side wall of the countersunk hole has a first side groove for the protrusion to enter, and a first chamfered surface is provided between the bottom surface of the first side groove and the cylindrical side wall of the countersunk hole. The side wall of the countersunk hole has a locking groove for the locking block to enter, and the locking groove is located below the first chamfered surface. The top surface of the locking groove and the top surface of the locking block are both horizontal planes or outwardly inclined planes, and there is a gap between the support member and the inner wall of the countersunk hole.

[0010] By further setting the above, by setting the first chamfered surface, when the support member is pressed down, the locking block is lowered to the height of the locking slot, and the locking block can be put into the locking slot by slightly swinging the adjustment switch sideways. When the pressure is released, the top surface of the locking slot contacts and abuts against the top surface of the locking block, and the support member is clamped. At this time, the downward pressing force can be released to enter and stably maintain the adjustment state of the adjustment switch: pushing the adjustment switch can push the main swing member, so that the contact swings and touches the trigger contact, and the seat is adjusted;

[0011] If you continue to press downward, the bottom surface of the protrusion will contact the first chamfered surface, so that the support member is squeezed and offset toward the position of the first chamfered surface, causing the locking block to disengage from the first side groove. At this time, the support member is reset by the action of the silicone rubber member. At this time, only the swing adjustment switch cannot control the action of the main swing member to trigger the adjustment, thereby avoiding accidental touching of the adjustment seat and affecting driving.

[0012] The utility model is further configured as follows: a limiting notch is provided on the side wall of the countersunk hole, and the limiting notch is in a long strip structure arranged along the movement direction of the support member, and the support member includes a convex corner, and the convex corner is located in the limiting notch.

[0013] With the above further settings, the convex angle and the limiting notch can limit the upper and lower limits of the movement of the support member, avoiding excessive downward movement that may damage the silicone rubber part, and also avoiding upward detachment from the main swing member or the secondary swing member.

[0014] A further further setting of the present utility model: a second side groove is provided on the side wall of the counterbore, a second chamfered surface is provided between the bottom surface of the second side groove and the cylindrical side wall of the counterbore, the second chamfered surface and the first chamfered surface are respectively on both sides of the counterbore, a groove is provided on the other side of the support member in the sinking groove, the top surface of the groove is a mating inclined surface, and the angle between the mating inclined surface and the horizontal plane is not greater than the angle between the second chamfered surface and the horizontal plane.

[0015] With the above further further setting, after the mating inclined surface contacts the second chamfered surface, it can push the support member towards the first chamfered surface side, ensuring the position of the support member when moving downward, ensuring that when the support member moves downward, the clamping block can approach and enter the clamping groove, and the protrusion can contact the first chamfered surface, ensuring that the clamping block can disengage from the clamping groove and complete the detachment action of the support member.

[0016] A further setting of the present utility model: an inner housing is provided on the mounting base, the mounting base and the inner housing cooperate to form a cavity for protecting the trigger, a sliding member for clamping the adjustment switch is slidably provided on the housing, an outer housing for protecting the mounting base and the inner housing is provided on the mounting base, and openings for the main swing member and the secondary swing member to extend out are respectively provided on the sliding member, the inner housing, and the outer housing.

[0017] With the above further setting, by setting the clamping connection between the sliding member and the adjustment switch, the stability of the adjustment switch is enhanced, and the sliding member slides on the inner housing without affecting the swing adjustment of the adjustment switch.

[0018] A further setting of the present utility model: the silicone rubber part has a cylindrical structure and there is a gap with the inner wall of the counterbore.

[0019] With the above further setting, when the silicone rubber part is extruded and deformed, it expands circumferentially, and the existence of the gap can ensure that the silicone rubber part can be deformed under pressure. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0031] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] It should be noted that in the description of the present utility model, all directional indications (such as up, down, front, back...) are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0033] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0034] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0035] like Figure 1-10 As shown, a seat adjustment switch support structure includes a mounting base 1, an adjustment switch 2 and a trigger 4 fixedly arranged on the mounting base 1. The mounting base 1 is provided with a main swing member 5 and a secondary swing member 6 that can swing in the same direction relative to the mounting base 1. The main swing member 5 and the secondary swing member 6 are both rotatably connected to the mounting base 1. The adjustment switch 2 can contact and drive the main swing member 5 after being pressed. The bottom of the main swing member 5 includes a contact 52 that can swing to contact the trigger 4 to control the contact.

[0036] A reset structure is provided on both the main swinging member 5 and the auxiliary swinging member 6. The reset structure includes a countersunk hole 8 and a silicone rubber member 7 arranged at the bottom of the countersunk hole 8. The countersunk hole 8 and the silicone rubber member 7 are both cylindrical structures and there is a gap between the silicone rubber member 7 and the inner wall of the countersunk hole 8. When the silicone rubber member 7 is squeezed and deformed, it expands in the circumferential direction. The existence of the gap can ensure that the silicone rubber member 7 can be compressed and deformed.

[0037] Each countersunk hole 8 is provided with a support member 9 for supporting the regulating switch 2. One end of the support member 9 contacts the silicone rubber member 7 for extrusion, and the other end of the support member 9 contacts the bottom of the regulating switch 2 for supporting force. The support member 9 is subjected to the pressure of the regulating switch 2 and moves up and down in the countersunk hole 8 to squeeze the silicone rubber member 7.

[0038] The bottom of the adjustment switch 2 includes a slide groove 21 for the support member 9 on the auxiliary swing member 6 to slide and a positioning hole 22 for positioning the support member 9 on the main swing member 5. The outer wall of the main swing member 5 includes a spherical surface 51 protruding outward and extending into the positioning hole 22. When the adjustment switch 2 is subjected to force, the support member 9 is squeezed to extend into the countersunk hole 8, so that the spherical surface 51 with a spherical structure extends into the positioning hole 22, ensuring that the main swing member 5 can be thrust by the positioning hole 22, thereby ensuring that the swing of the main swing member 5 can achieve seat adjustment, and the slide groove 21 can allow the support member 9 to slide on it, reducing the connection structure between the adjustment switch 2 and the auxiliary swing member 6, thereby avoiding the influence of the shaking of the auxiliary swing member 6 on the adjustment switch 2, so as to avoid the influence on the main swing member 5, enhance the control accuracy of the main swing member 5, and thus enhance the accuracy of seat adjustment.

[0039] Each support member 9 includes a protrusion 92 located on the side wall and a recessed groove 93 located below the protrusion 92, and the recessed groove 93 and the bottom of the support member 9 form a locking block 94; the side walls of the countersunk hole 8 on both sides are respectively provided with a first side groove 83 and a second side groove 85, the first side groove is for the protrusion 92 to enter, and a first chamfered surface 84 is provided between the bottom surface of the first side groove 83 and the cylindrical side wall of the countersunk hole 8, the first chamfered surface 84 can be an arc surface or an inclined surface, and in this embodiment, the first chamfered surface 84 is preferably an inclined surface, and the side wall of the countersunk hole 8 is provided with a locking groove 82 for the locking block 94 to enter, and the locking groove 82 is located below the first chamfered surface 84, the top surface of the locking groove 82 and the top surface of the locking block 94 are both planes, and are both perpendicular to the direction in which the support member 9 extrudes the silicone rubber member 7, and there is a gap between the support member 9 and the inner wall of the countersunk hole 8, so that the support member 9 can move in the horizontal direction in the countersunk hole 8.

[0040] When the support member 9 is pressed down, the locking block 94 is lowered to the height of the locking groove 82, and the locking block 94 can be put into the locking groove 82 by slightly swinging the adjustment switch 2 sideways. At this time, the spherical surface 51 of the main swing member 5 enters the positioning hole 22, and the adjustment switch 2 enters the adjustment state: pushing the adjustment switch 2 can push the main swing member 5, so that the contact 52 swings and touches the contact of the trigger 4, and the seat is adjusted;

[0041] At this time, the pressing is released, and the top surface of the positioning groove 82 and the top surface of the positioning block 94 are in conflict with each other under the elastic force of the silicone rubber member 7, thereby locking the support member 9, and the downward pressing force can be released to stably maintain the adjustment state of the adjustment switch 2;

[0042] If the pressure continues to be pressed downward, the bottom surface of the protrusion 92 contacts the first chamfered surface 84, and the protrusion 92 is squeezed to drive the entire support member 9 to shift toward the position of the first chamfered surface 84, so that the locking block 94 disengages from the first side groove 83. At this time, the downward pressing force is released, and the support member 9 is reset by the action of the silicone rubber member 7. The spherical surface 51 of the main swing member 5 leaves the positioning hole 22. At this time, the swing adjustment switch 2 cannot control the movement of the main swing member 5, and thus the contact 52 cannot touch the trigger 4 contact to adjust the seat, which can avoid the seat adjustment action caused by accidentally touching the adjustment switch 2, thereby affecting driving.

[0043] Further, in order to control the position of the support member 9 in the countersunk hole 8 when pressed, a second chamfered surface 86 is provided between the bottom surface of the second side groove 85 and the cylindrical side wall of the countersunk hole 8, and the second chamfered surface 86 and the first chamfered surface 84 are respectively located on both sides of the countersunk hole 8, and the support member 9 is provided with a groove 95 on the other side of the countersunk groove 93, and the top surface of the groove 95 is a matching inclined surface 96, and the angle between the matching inclined surface 96 and the horizontal plane is not greater than the angle between the second chamfered surface 86 and the horizontal plane. During the pressing process of the support member 9, the contact between the matching inclined surface 86 and the second chamfered surface 86 precedes the contact between the protrusion 92 and the first chamfered surface 84;

[0044] After the mating inclined surface 96 contacts the second chamfered surface 86, it can push the support member 9 towards the first chamfered surface 84. When the support member 9 moves downward, the clamping block 94 approaches and enters the clamping groove 82, so that the locking of the support member 9 in the counterbore 8 can be completed, and the protrusion 92 can smoothly contact the first chamfered surface 84, ensuring that the clamping block 94 can be disengaged from the clamping groove 82 and the detachment of the support member 9 can be completed.

[0045] Furthermore, a limiting notch 81 is provided on the side wall of the counterbore 8. The limiting notch 81 is a strip-shaped structure arranged along the movement direction of the support member 9. The support member 9 includes a convex corner 91, and the convex corner 91 is located in the limiting notch 81. In this embodiment, the limiting notch 81 is arranged below the second chamfered surface 86, and the convex corner 91 is arranged at the bottom of the groove 92, which is convenient for processing. The convex corner 91 and the limiting notch 81 can limit the upper and lower limits of the movement of the support member 9, avoiding damage to the silicone rubber part 7 caused by excessive downward movement, and avoiding upward detachment from the main swing member 5 or the auxiliary swing member 6.

[0046] An inner housing 10 is provided on the mounting base 1. The mounting base 1 and the inner housing 10 cooperate to form a cavity for protecting the trigger 4 and the rotating connection structure on the mounting base 1. The housing 10 can be split into upper and lower parts, and the two parts can be detachably connected through a snap structure, which is convenient for disassembly and maintenance.

[0047] A sliding member 11 for clamping the adjustment switch 2 is placed above the inner housing 10. The sliding member 11 includes a clamping part for clamping the adjustment switch 2 and a flat part integrated with the clamping part. The flat part of the sliding member 11 is on the upper surface of the inner housing 10 and can slide relative to the surface of the inner housing 10, which can limit the swinging direction of the adjustment switch 2, and the sliding member 11 can be used as a counterweight for the adjustment switch 2 to enhance the stability of the adjustment switch 2.

[0048] An outer housing 12 for protecting the mounting base 1 and the inner housing 10 is provided on the mounting base 1. The outer housing 12 is connected to the mounting plate 1 by screws, making the whole appearance beautiful and simple.

[0049] Openings for the main swing member 5 and the auxiliary swing member 6 to extend are provided on the sliding member 11, the inner housing 10, and the outer housing 12. Thus, the adjustment switch 2 is located outside the outer housing 12, which is convenient for the driver to adjust. A hand-held part is provided outside the adjustment switch 2 to further improve the operation feel of the driver.

[0050] Specifically, a support member 9 is provided below the adjustment switch 2. The support member 9 presses the silicone rubber member 7 to cause deformation, and the structure in the counterbore 8 holds the support member 9 in place, so that the main swing member 5 enters the positioning hole 22 and is adjusted under the control of the adjustment switch 2. After the pressure is removed, the support member 9 can reset under the elastic force of the silicone rubber member 7, and the main swing member 5 disengages from the positioning hole 22. Compared with the spring in the prior art, the silicone rubber member 7 is soft and elastic as a whole. While the adjustment switch 2 can be reset, no noise is generated during the deformation and reset processes of the silicone rubber member 7. When the vehicle is running, no noise is generated when the adjustment switch 2 shakes and drives the support member 9 and the silicone rubber member 7 to move, and no noise is generated during the operation of pressing the silicone rubber member 7 to deform, resulting in a good user experience for the driver.
