Description

Technical Field

[0001] This utility model relates to the field of button installation technology, specifically to a door panel button installation structure. Background Technology

[0002] Vehicle door trim panels typically integrate physical buttons for controlling functions such as window raising and lowering, rearview mirror folding, and door locking / unlocking. These buttons need to be reliably fixed to the door panel, while also being easy to remove for maintenance or replacement.

[0003] In existing technologies, the connection between button panels and buttons typically requires numerous screws, making the connection cumbersome and complicated. The connection between buttons and door panels usually relies on multiple screws for fastening. This multi-screw fixing method leads to a cumbersome assembly process, requiring workers to repeatedly operate and tighten multiple screws within limited installation space, severely restricting production line pace and efficiency. When button maintenance or replacement is needed, the tedious disassembly process is also a pain point. Operators must accurately locate all screw positions and unscrew them one by one. In the poorly lit door lining, this process is prone to problems such as lost screws and slipping tools, increasing the cost and difficulty of after-sales service. Utility Model Content

[0004] The purpose of this utility model is to provide a door panel button installation structure that can solve the problem of the large workload in the installation of existing car door buttons.

[0005] To achieve the above objectives, this utility model proposes a door panel button mounting structure, including a groove in the door panel, a button housing installed in the groove, a circuit board fixedly installed inside the button housing, a keycap installed on the top of the circuit board via a button, a decorative piece sleeved on the top of the keycap, a circular hole in the center of the circuit board, a first threaded hole in the bottom of the button housing, a bolt installed in the first threaded hole, a cam fixedly installed on the side wall of the bolt, a spring fixedly installed between the cam and the button housing, and several windows opened along the circumferential side wall of the button housing, with retaining strips installed in the windows and abutting plates installed at the ends of the retaining strips; A second threaded hole is opened at the bottom of the groove, and a limiting groove is opened on the side wall of the groove and corresponding to the window hole. A spring plate is installed between the abutment plate and the side wall of the groove. The rotation of the cam pushes the locking strip to slide in the window and the limiting groove. The bolt is installed in the first threaded hole and the second threaded hole through the thread.

[0006] Further configured, the cam includes a plurality of protrusions evenly distributed circumferentially along the center of the cam, a first arc surface is provided between the protrusions, a second arc surface is provided at the end of the cam, and a third arc surface is provided at the end of the abutment plate. The radius of the third arc surface is smaller than that of the first arc surface, and the third arc surface contacts the first arc surface under the action of the spring sheet.

[0007] A further configuration is that a limiting cylinder is fixedly installed on the inner wall of the button housing, the limiting cylinder is located below the retaining strip, and the spring sheet is installed inside the limiting cylinder.

[0008] Further configured, the limiting cylinder has openings at both ends, the spring sheet has a wavy cross-section, the spring sheet has an arc surface at the bend, one end of the spring sheet is fixedly installed on the inner wall of the button housing, and the other end of the spring sheet is fixedly installed on the side wall of the abutment plate.

[0009] A further configuration is provided, wherein a positioning groove is formed on the outer wall of the button housing, and a protrusion is provided on the inner wall of the groove corresponding to the positioning groove, and the protrusion can be installed in the positioning groove.

[0010] A further configuration is that the spring is sleeved on the bolt sidewall below the cam, one end of the spring is fixedly installed on the lower sidewall of the cam, and the other end of the spring is fixedly installed on the inner wall of the button housing.

[0011] A further configuration is provided, wherein a threaded seat is fixedly installed at the bottom of the button housing, a threaded cavity is formed inside the threaded seat, and a circular hole is formed on the circuit board corresponding to the threaded seat.

[0012] A further configuration is that the circuit board is fixed to the threaded seat after the mounting screw passes through the circular hole.

[0013] Further configured, the decorative element is made of rubber, and the decorative element includes a disc, with a snap ring fixedly installed on the top of the disc.

[0014] A further configuration is provided, wherein the top of the keycap is provided with an arrow groove, and the connecting ring is sleeved on the side of the arrow groove.

[0015] The beneficial effects of one or more of the above technical solutions: This invention uses a bolt (connected to the button by a spring) to drive a cam to rotate. As the bolt tightens, the cam pushes out a retaining strip at the bottom, thus locking it into a groove in the door panel. During disassembly, the bolt rotates in the opposite direction and is unscrewed from the threaded hole. The retaining strip then rebounds through an elastic plate and is pushed out of the groove. Disassembly is quick, thus achieving both circumferential positioning and fixation of the button with just one bolt. This ensures a stable connection of the button to the car door panel while improving disassembly speed. Attached Figure Description

[0024] The specific implementation of this embodiment will now be described with reference to the accompanying drawings.

[0025] A door panel button mounting structure, as shown in the reference. Figures 1-3The device includes a groove 2 formed in the door panel 1, a button housing 3 installed in the groove 2, a circuit board 4 fixedly installed inside the button housing 3, a keycap 6 installed on the top of the circuit board 4 via a button 5, a decorative piece 7 sleeved on the top of the keycap 6, the button 5 can be an existing conductive carbon particle button or a silicone button, a circular hole 41 is formed in the center of the circuit board 4, a first threaded hole 31 is formed at the bottom of the button housing 3, a bolt 8 is installed in the first threaded hole 31, a cam 9 is fixedly installed on the side wall of the bolt 8, a spring 10 is fixedly installed between the cam 9 and the button housing 3, and a plurality of windows 32 are formed along the circumferential side wall of the button housing 3, a retaining strip 11 is installed in the window 32, and an abutting plate 12 is installed at the end of the retaining strip 11; A second threaded hole 21 is opened at the bottom of the groove 2, and a limiting groove 22 is opened on the side wall of the groove 2 corresponding to the window opening. A spring sheet 13 is installed between the abutment plate 12 and the side wall of the groove 2. The rotation of the cam 9 pushes the locking strip 11 to slide in the window 32 and the limiting groove 22. The bolt 8 is simultaneously installed in the first threaded hole 31 and the second threaded hole 21 through threads, which simplifies the installation process while ensuring reliable circumferential limiting. By screwing the bolt 8 into the first threaded hole 31 and the second threaded hole 21 at the same time, the button housing 3 is quickly fixed, avoiding transmission. The cumbersome operation of multi-screw installation is significantly improved, increasing production line cycle time and assembly efficiency. When the bolt 8 rotates, the cam 9 pushes the retaining strip 11 to slide along the window 32 and the limiting groove 22, so that the retaining strip 11 is engaged in the limiting groove 22 of the groove 2, forming a mechanical interlock. This ensures the circumferential stability of the button 18 on the door panel 1, preventing loosening or rotation during use and improving disassembly speed. When the bolt 8 is unscrewed, the cam 9 rotates in the opposite direction, and under the action of the spring plate 13, the retaining strip 11 automatically exits from the limiting groove 22, simplifying the disassembly process and reducing maintenance difficulty and time.

[0026] Reference Figure 4 and Figure 5 The cam 9 includes a plurality of protrusions 91 evenly distributed circumferentially along the center of the cam 9. A first arc surface 92 is provided between the protrusions 91. A second arc surface 93 is provided at the end of the cam 9. A third arc surface 121 is provided at the end of the abutment plate 12. The radius of the third arc surface 121 is smaller than that of the first arc surface 92. The third arc surface 121 contacts the first arc surface 92 under the action of the spring plate 13. (Refer to...) Figure 5 At this point, button 18 is not installed inside the vehicle panel. The third arc surface 121 of the abutting plate 12 abuts against the first arc surface 92, and the retaining strip 11 is in the retracted state (located inside the button housing 3, not in contact with the limiting groove 22). (Refer to...) Figure 4When the cam 9 rotates during the tightening of the bolt 8, the rotation of the cam 9 causes the original first arc surface 92 to rotate into the second arc surface 93, increasing the circular distance between the abutment plate 12 and the cam 9. Since the abutment plate 12 is always in contact with the cam 9, the rotation of the cam 9 causes the abutment plate 12 to move linearly. The abutment plate 12 drives the retaining strip 11 to extend out of the window 32 and into the limiting groove 22. The protrusion 91 and the first arc surface 92 on the cam 9 are designed to contact the third arc surface 121 of the abutment plate 12. At the same time, it can achieve smooth linear push, reduce jamming and wear, and ensure smooth extension and retraction of the locking strip 11. The radius of the third arc surface 121 is smaller than that of the first arc surface 92. Under the action of the spring plate 13, it maintains close contact, which improves the force transmission efficiency between the cam 9 and the abutment plate 12, making the locking of the locking strip 11 in the limiting groove 22 more reliable. The protruding part of the protrusion 91 presses against the abutment plate 12 when the bolt 8 is tightened, forming a self-locking effect to prevent the locking strip 11 from accidentally exiting after the bolt 8 is loosened.

[0027] A limiting cylinder 14 is fixedly installed on the inner wall of the button housing 3. The limiting cylinder 14 is located below the retaining strip 11. The spring plate 13 is installed inside the limiting cylinder 14. The limiting cylinder 14 is fixed to the inner wall of the button housing 3, providing a precise guide path for the spring plate 13 and the retaining strip 11, ensuring that the retaining strip 11 moves linearly within the window 32, avoiding skewness or jamming. The spring plate 13 is installed inside the limiting cylinder 14, which restricts the lateral movement of the spring plate 13, improves the accuracy of its elastic reset, and can quickly push the retaining strip 11 back to its original position when the bolt 8 is unscrewed, improving the disassembly response speed.

[0028] The limiting cylinder 14 has openings at both ends. The spring plate 13 has a wavy cross-section and an arc surface at the bend. This increases the range of elastic deformation, allowing the spring plate 13 to store more energy when compressed and provide a stronger rebound force when released, ensuring that the locking strip 11 quickly exits the limiting groove 22. One end of the spring plate 13 is fixedly installed on the inner wall of the button housing 3, and the other end is fixedly installed on the side wall of the abutting plate 12. This forms a stable force transmission chain, ensuring the synchronicity of the locking strip 11's movement.

[0029] A positioning groove 33 is formed on the outer wall of the button housing 3. A protrusion 23 is provided on the inner wall of the groove 2 corresponding to the positioning groove 33. The protrusion 23 can be installed in the positioning groove 33. The positioning groove 33 cooperates with the protrusion 23 on the inner wall of the groove 2 to guide the button housing 3 to be accurately positioned in the initial stage of installation, prevent misalignment or rotation, and simplify the alignment steps. After the protrusion 23 is embedded in the positioning groove 33, it works in conjunction with the limiting mechanism of the retaining strip 11 to further enhance the circumferential stability of the button housing 3.

[0030] Spring 10 is sleeved on the side wall of bolt 8 below cam 9. One end of spring 10 is fixedly installed on the lower side wall of cam 9, and the other end of spring 10 is fixedly installed on the inner wall of button housing 3. Spring 10 is sleeved on the side wall of bolt 8, connecting cam 9 and inner wall of button housing 3. When bolt 8 is tightened, it is compressed and stores elastic potential energy. When bolt 8 is unscrewed, spring 10 releases energy, pushes cam 9 to reset, and auxiliary retainer 11 retracts, realizing quick disassembly. Since both ends of spring 10 are fixedly installed in cam 9 and button housing 3, it is ensured that when bolt 8 is disassembled, the length of bolt 8 in contact with the second threaded hole 21 is less than the contact thickness between cam 9 and abutment plate 12. This ensures that when bolt 8 is completely unscrewed from the second threaded hole 21, cam 9 is still in contact with abutment plate 12, thus ensuring that when bolt 8 is tightened again, cam 9 can directly drive the movement of abutment plate 12 and front retainer 11.

[0031] To ensure the installation of the circuit board 4 within the button housing 3, a threaded seat 15 is fixedly installed at the bottom of the button housing 3. The threaded seat 15 has a threaded cavity, and the circuit board 4 has a circular hole 41 corresponding to the threaded seat 15. The circular hole 41 passes through the mounting screw 16, which then fixes the circuit board 4 onto the threaded seat 15. The screw 16 passes through the circular hole 41 of the circuit board 4 and is screwed into the threaded seat 15, firmly fixing the circuit board 4 within the button housing 3. The screw 16 fixing method is simple, and when the circuit board 4 needs to be replaced, it can be disassembled simply by unscrewing the screw 16, making maintenance convenient.

[0032] The decorative part 7 is made of rubber. The rubber material of the decorative part 7 is elastic and can tightly conform to the surface of the keycap 6 and the door panel 1, providing a good sealing effect, preventing dust or moisture from entering the inside of the button 18, and extending its service life. The decorative part 7 includes a disc 171, and a connecting ring 172 is fixedly installed on the top of the disc 171. The design of the disc 171 and the connecting ring 172 of the decorative part 7 allows it to be quickly fitted onto the keycap 6 without additional tools, simplifying the assembly process. An annular protrusion 173 is provided inside the connecting ring 172. Figure 7 An annular groove 174 is formed in the corresponding protrusion on the side 63 of the groove. The diameter of the annular groove is smaller than the diameter of the protrusion. The sleeve buckle 172 is sleeved in the side 63 of the groove of the top sleeve groove 62 of the keycap 6. During installation, the annular protrusion is inserted into the annular groove (at this time, the rubber material causes the annular protrusion to deform). Since the decorative part 7 is made of rubber, when installing or removing the bolt 8, the decorative part 7 can be pulled off or put on from the side 63 of the groove of the sleeve groove 62 of the keycap 6 by the sleeve buckle 172. The rubber tightening action achieves locking, which is convenient for disassembly and prevents the decorative part 7 from sliding or falling off during operation.

[0033] Reference Figure 2 The top of keycap 6 has an arrow groove 61. The arrow serves as an indicator, improving the visual recognition of button 18 and facilitating user operation. Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
