Technical Field

[0001] This utility model relates to the field of automotive switch technology, specifically to a novel waterproof cover switch. Background Technology

[0002] Existing switches have waterproof requirements, and the conventional treatment for existing waterproof switches is to achieve protection by potting. After potting, the product cannot be reworked or repaired. Furthermore, to ensure that the potted product has a smooth and unblemished surface, it needs a long time to cure naturally, resulting in a long production cycle, serious inventory accumulation during mass production, and huge investment in turnover jigs.

[0003] In addition, existing switches often have assembly errors that fail to identify quality issues during assembly. To address these problems, there is an urgent need to design a new type of switch that does not require waterproofing with potting compound and can prevent assembly errors during manual assembly.

A button is installed inside the button, and anti-misalignment positioning surfaces are provided on opposite sides of one end of the button, conforming to the shape of the button's inner wall. The bottom of the button is close to the top surface of the sealing gasket and directly above the switch, while the top of the button is close to the top of the button's inner wall.

[0007] The top cover has a ring-shaped structure, and anti-misalignment positioning ribs are provided on opposite sides of its inner ring wall. Anti-misalignment positioning grooves are provided at the bottom of the button around each of the anti-misalignment positioning ribs. The button is inserted into the top cover from the bottom, and the anti-misalignment positioning grooves are inserted into the corresponding anti-misalignment positioning ribs. The button protrudes from the top of the top cover, and its bottom is locked inside the top cover.

[0008] The top cover has multiple latching ears arranged in an error-proof layout around its perimeter. The base has latching blocks arranged around its perimeter corresponding to each latching ear. The latching ears are latched and connected to the corresponding latching blocks. The sealing gasket is clamped between the base and the top cover. The button is covered with a waterproof rubber ring, which is installed on the top of the top cover.

[0009] A sealing plug is provided at the bottom of the base, and a wire harness is soldered onto the circuit board. The wire harness passes through the sealing plug and extends out of the bottom of the base.

[0010] In a preferred embodiment of this utility model, the number of latching ears is six, with two latching ears forming a group. The two groups of latching ears are respectively disposed on the front and rear sides of the upper cover. One latching ear is disposed on each of the left and right sides of the upper cover. The spacing between the two latching ears on the front side is different from the spacing between the two latching ears on the rear side. Limiting flanges are provided on both the front and rear sides of the base and between the two latching blocks. The length of the limiting flanges matches the gap between the corresponding two latching ears.

[0011] In a preferred embodiment of this utility model, anti-misalignment flanges are provided at both ends of the sealing gasket and at each of the corresponding limiting flanges, and the length of the anti-misalignment flange is equal to the length of the corresponding limiting flange.

[0012] In a preferred embodiment of this utility model, the number of the anti-misalignment positioning ribs is four, and two anti-misalignment positioning ribs on the same side form a group. The two groups of anti-misalignment positioning ribs are respectively arranged on opposite sides of the inner ring wall of the upper cover and are staggered from each other.

[0013] In a preferred embodiment of this utility model, a sealing rib is provided around the bottom of the top cover, and the sealing rib presses against the top of the sealing gasket.

[0014] In a preferred embodiment of this utility model, clearance grooves are provided at the four corners of the top of the upper cover.

[0018] In a preferred embodiment of this utility model, a sealing ring is provided on the outside of the wire harness, and the sealing ring is inserted into the inside of the base.

[0019] The beneficial effects of this utility model are:

[0020] This utility model, through its assembled structural design, combined with waterproof and error-proof structures, effectively solves the technical problem that conventional waterproof switch treatment methods rely on glue injection for protection, and that products cannot be reworked or repaired after glue injection. Moreover, compared to glue-injected products, which require a long time for natural curing to ensure a smooth and normal glue surface, resulting in a long production cycle, serious inventory accumulation during mass production, and huge investment in turnover fixtures, this utility model also solves the problem.

It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0029] Example:

[0030] like Figure 1-5 As shown, this embodiment provides a novel waterproof cover switch, including a base 8, a button 3, and a top cover 2. Two insertion posts 82 are arranged side by side near the center of the top of the base 8. Both insertion posts 82 are inserted and positioned into the center of the circuit board 7. The circuit board 7 rests in the top recess of the base 8. A switch 6 is set on the top of the circuit board 7. Positioning posts 81 are set at the four corners of the top of the base 8. A sealing gasket 5 is inserted between the four positioning posts 81. Positioning holes 24 are opened at the bottom of the top cover 2 corresponding to each positioning post 81. The positioning holes 24 are inserted into the corresponding positioning posts 81. The sealing gasket 5 is located between the top cover 2 and the base 8. A button 4 is installed inside the button 3. An anti-misalignment positioning surface 41 is set on the opposite side of one end of the button 4, which fits the shape of the inner wall of the button 3. The bottom of the button 4 is close to the top surface of the sealing gasket 5 and is directly above the switch 6. The top of the button 4 is close to the top of the inner wall of the button 3.

[0031] The top cover 2 has a ring structure, and anti-misalignment positioning ribs 23 are provided on opposite sides of its inner ring wall. Anti-misalignment positioning grooves 31 are provided at the bottom of the button 3 around each anti-misalignment positioning rib 23. The button 3 is inserted into the top cover 2 from the bottom, and the anti-misalignment positioning grooves 31 are inserted into the corresponding anti-misalignment positioning ribs 23. The button 3 protrudes from the top of the top cover 2, and its bottom is locked inside the top cover 2.

[0032] The top cover 2 has multiple latch ears 22 arranged in an error-proof layout around its perimeter. The base 8 has latch blocks 83 arranged around its perimeter corresponding to each latch ear 22. The latch ears 22 are latched and connected to the corresponding latch blocks 83. The sealing gasket 5 is clamped between the base 8 and the top cover 2. The button 3 is covered with a waterproof rubber ring 1, which is installed on the top of the top cover 2.

[0033] A sealing plug 10 is provided at the bottom of the base 8, and a wire harness 9 is soldered to the circuit board 7. The wire harness 9 passes through the sealing plug 10 and extends out of the bottom of the base 8.

[0034] In a preferred embodiment of this utility model, the inner edge of the waterproof rubber ring 1 is provided with a beveled ridge 12, and the vertical surface of the beveled ridge 12 is in close contact with the outer wall of the button 3.

[0035] In a preferred embodiment of the present invention, a sealing ring 85 is further provided on the outside of the wire harness 9, and the sealing ring 85 is inserted into the inside of the base 8.

[0036] In a preferred embodiment of this utility model, a sealing rib 25 is further provided around the bottom of the top cover 2, and the sealing rib 25 presses against the top of the sealing gasket 5.

[0037] Specifically, such as Figure 1-3 As shown, by setting the base 8 and the upper cover 2 to be snapped together, a clamping force is provided for the switch structure. The circuit board 7, switch 6, sealing gasket 5, button 4, and push button 3 are sequentially installed between the base 8 and the upper cover 2 from bottom to top. The pressure generated by the snap-fit ​​connection between the upper cover 2 and the base 8, along with the pressure of the base 8 clamping the sealing gasket 5, achieves a seal on the circuit board 7 and switch 6 covered by the sealing gasket 5. This gives the switch excellent waterproof performance while also allowing for disassembly and maintenance. Furthermore, a channel for the wire harness 9 to extend from the lower part of the base 8 is provided, and a sealing ring 85 and a sealing plug are used to seal the connection. Ten channels are sealed, thus satisfying the waterproof function of the base 8 while also allowing for disassembly and repair. In addition, by setting a raised sealing rib 25 around the bottom of the top cover 2, the waterproof performance of the sealing gasket 5 is further enhanced through tight sealing between the lines. This effectively solves the technical problem that the conventional treatment of waterproof switches 6 in the existing technology is to achieve protection by potting glue. After potting, the product cannot be reworked or repaired. Furthermore, potted products require a long time to naturally cure to ensure that the potting surface is flat and without abnormalities, resulting in a long production cycle, serious inventory accumulation during mass production, and huge investment in turnover fixtures, causing considerable losses to the enterprise.

[0038] Furthermore, by eliminating the potting process, the investment in potting fixtures and equipment is reduced, the glue curing time is shortened, and the product production time is reduced, thus meeting the requirements for waterproof use. Moreover, the inclined structure of the waterproof rubber ring 1, which matches the button 3, provides protection against external contaminants, further enhancing the sealing and waterproof performance of this switch.

[0039] Secondly, by setting anti-misassembly structures at the waterproof rubber ring 1, top cover 2, button 3, sealing gasket 5, and base 8, the quality problem of frequent assembly errors during the assembly of the existing switch 6 is effectively solved. This enables automated production of the product, and the assembly position can be automatically identified through the anti-misassembly structure, avoiding assembly abnormalities during manual assembly, thereby effectively improving the production efficiency and product quality of the product.

[0040] In a preferred embodiment of this utility model, the number of latch ears 22 is further six, with two latch ears 22 forming a group. The two groups of latch ears 22 are respectively disposed on the front and rear sides of the upper cover 2. One latch ear 22 is disposed on each of the left and right sides of the upper cover 2. The spacing between the two latch ears 22 on the front side is different from the spacing between the two latch ears 22 on the rear side. Limiting flanges 84 are provided on both the front and rear sides of the base 8 and between the two latch blocks 83. The length of the limiting flanges 84 matches the gap between the corresponding two latch ears 22.

[0041] In a preferred embodiment of the present invention, the sealing gasket 5 is further provided with anti-misalignment flanges 51 at both ends of the sealing gasket 5 and at each corresponding limiting flange 84, and the length of the anti-misalignment flange 51 is equal to the length of its corresponding limiting flange 84.

[0042] In a preferred embodiment of this utility model, the number of anti-misalignment positioning ribs 23 is further four, with two anti-misalignment positioning ribs 23 on the same side forming a group, and the two groups of anti-misalignment positioning ribs 23 being respectively disposed on opposite sides of the inner ring wall of the upper cover 2 and staggered from each other.

[0043] In a preferred embodiment of this utility model, furthermore, a relief groove 21 is provided at each of the four corners of the top of the top cover 2. By providing the relief groove 21, interference between the switch and the equipment mechanism during installation can be effectively avoided, and deformation of the plastic part can also be prevented during the injection molding process.

[0044] In a preferred embodiment of this utility model, one of the two error-proof positioning surfaces 41 is an inclined surface, and the other is an arc surface that is recessed into the button 4.

[0045] In a preferred embodiment of this utility model, the waterproof rubber ring 1 is further provided with anti-misalignment protrusions 11 on opposite sides of its bottom. The two anti-misalignment protrusions 11 have the same length but different widths. The top of the cover 2 is provided with a matching mounting groove corresponding to each anti-misalignment protrusion 11.

[0046] Specifically, such as Figure 3-5 As shown, by setting two anti-misalignment protrusions 11 opposite each other at the bottom of the waterproof rubber ring 1, and by setting the width of the two anti-misalignment protrusions 11 to different sizes, and by opening an installation groove on the top surface of the upper cover 2 that matches the size of the two, the waterproof rubber ring 1 can only be assembled with the upper cover 2 in one direction, thereby achieving its anti-misalignment function.

[0047] By setting the position of the latch ears 22 around the top cover 2, by setting the distance between the two sets of latch ears 22 arranged side by side on the front and back sides to different sizes, and by setting the latch blocks 83 at the corresponding positions around the base 8, the top cover 2 can only be latched to the base 8 in one direction, thereby achieving its anti-misinstallation function.

[0048] Similarly, by setting two sets of anti-misalignment positioning ribs 23 and anti-misalignment positioning grooves 31 with different spacings inside the top cover 2 and outside the button 3, and matching them by setting different spacing sizes, the button 3 can only be installed into the top cover 2 in one direction, thereby realizing its anti-misalignment function.

[0049] Button 4 achieves its anti-misassembly function by setting two anti-misassembly positioning surfaces 41, one beveled and the other concave arc surface, on both sides of one end, which fit into the internal structure of button 3.

[0050] Finally, by setting anti-misalignment flanges 51 and limiting flanges 84 of different lengths at the front and rear ends of the sealing gasket 5 and the front and rear sides of the base 8 respectively, the installation direction can be distinguished, thereby realizing its anti-misalignment function.

[0051] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
