Description

Technical Field

[0001] This application relates to automotive parts, and more particularly to an automatic switch for a car trunk. Background Technology

[0002] The automatic trunk switch is an automotive electrical component that includes a switch body, a base, a flexible support, a key cover, decorative parts, and a keycap.

[0003] The switch body is an electrical component, comprising a base and a trigger rod slidably connected to the center of the base. The base is rectangular and contains circuit components such as contacts. When the trigger rod is pressed and slides inward into the base, it pushes the internal contacts, connecting the circuit and enabling the transmission of electrical signals.

[0004] The base is fitted over the base, the key cover is fastened to the end of the trigger rod, the key cap is fastened to the key cover, and the elastic support is made of elastic material, which connects the key cover and the base.

[0005] The decorative element is hollow inside and open at both ends. One end of the decorative element is fitted onto the base, and the inner side of the decorative element is snapped into and fixed to the base, so that the end of the trigger rod, the elastic support, the key cover, and the keycap are all located inside the decorative element. The key cover protrudes from the other end of the decorative element, and there is a gap between the key cover and the inner side of the decorative element. Pressing the key cover allows it to slide smoothly into the decorative element, and pushing the key cover presses against the trigger rod.

[0006] In actual use, due to the gap between the keycap and the inner side of the decorative part, liquids, debris, or other impurities can enter the automatic trunk switch through this gap, hindering the keycap's normal pressing and rebound. In this case, it is necessary to disassemble the decorative part and base for cleaning. Because the existing fitting between the decorative part and base is tight, disassembly requires inserting a flathead screwdriver or jack into the gap to pry the decorative part out. This disassembly process is difficult and easily damages the base or decorative part. If a damaged part is out of stock, it is necessary to contact after-sales service to have it replaced by the original manufacturer, which takes a long time and affects the consumer's user experience. Utility Model Content

[0007] To address the problem of difficulty in disassembling the base and trim of existing automatic trunk switches, which can easily lead to damage to the base and trim during disassembly and render them unusable, an automatic trunk switch for automobiles is provided.

[0008] The above-mentioned objective of this utility model is achieved through the following technical solution: An automatic trunk switch for automobiles includes a switch body, a base, an elastic support, a key cover, a decorative part, and a keycap. The decorative part includes a mounting end and a display end located on both sides. The decorative part is hollow inside and has openings at the mounting end and the display end. The mounting end is sleeved onto one end of the base. The switch body is located inside the base, and one end of it is inserted into the decorative part. The key cover is fastened to the switch body inserted into the decorative part. The elastic support is made of elastic material and connects the key cover and the base. The keycap is inserted into the decorative part from the display end, and the keycap is fastened to the key cover. The mounting end includes a mounting side with a slot and a deformation opening. The deformation opening penetrates the inside and outside of the mounting end and extends from the mounting end to the display end. A locking block is fixed to the side of the base inserted into the mounting end and is inserted into and locked into the slot. A protruding prying member is also provided on the outer side wall of the decorative part where the slot is located.

[0009] By adopting the above technical solution, the installation end and the display end can be connected together, and the slot and the block can be engaged to fix the decorative parts and the base. When liquids or debris enter the decorative part through the gap between the display end and the keycap, it will affect the normal pressing and rebound of the keycap. In this case, it is necessary to disassemble the decorative part and the base for cleaning. In this application, the design of the deformation opening increases the amount of torsional deformation that the end side of the mounting end can undergo without damaging the result; Manually apply force from the installation end to the display end to press against the prying component, and then pry the entire decorative component. This causes the installation end to deform quickly, allowing the locking block to disengage from the slot and the decorative component to detach from the base, achieving quick disassembly and convenient maintenance. During this process, the decorative component and base structure remain intact and can be reused.

[0010] Optionally, the prying member includes a prying block; the prying block includes a fixed end fixed to the outer side of the decorative member and a force-receiving end extending toward the display end.

[0011] By adopting the above technical solution, the force-bearing end is closer to the display end, so that a person can press and apply force with one thumb to simultaneously press and pry the prying part and the entire decorative part, thereby further facilitating the disassembly and cleaning of the base and decorative parts.

[0012] Optionally, the prying block is inclined away from the outer side of the decorative piece from the fixed end toward the force-bearing end.

[0013] By adopting the above technical solution, when the force-bearing end is compressed, the side of the mounting end is more likely to tilt away from the base, which further facilitates the separation of the slot and the block, making disassembly more convenient.

[0014] Optionally, the prying member further includes a reinforcing block located on the side of the fixed end facing the display end, and the reinforcing block is located between the fixed end and the outer side of the decorative member and connects the two.

[0015] By adopting the above technical solution, the strength of the prying component is enhanced, reducing the possibility of breakage when the prying block is bent under pressure.

[0016] Optionally, the dimension of the fixed end is larger than that of the reinforcing block in both the direction perpendicular to the fitting of the decorative piece and the base and the direction of inclination of the prying block.

[0017] By adopting the above technical solution, the strength of the prying component and the space allowance for the bending deformation of the prying block are balanced, so that when the prying block is bent under pressure, it is easier to bend and pry the side wall of the installation end, while it is not easy to break due to bending.

[0018] Optionally, the prying member includes a force-receiving end for applying pressure, the end face of which has anti-slip texture.

[0019] By adopting the above technical solution, it is easy to apply force with the thumb, and it is convenient to disassemble the base and decorative parts.

[0020] Optionally, the card slot is larger than the card block.

[0021] By adopting the above technical solution, a clearance is left between the side wall of the slot and the card block, which facilitates the deformation of the side wall of the installation end, reduces the force required for the prying component to pry the side wall of the installation end to deform and the amount of torsional deformation required for the side wall of the installation end, and further facilitates the disassembly of the base and decorative parts.

[0022] Optionally, the base has a limiting block on the side facing the mounting end, and the limiting block abuts against the mounting end.

[0023] By adopting the above technical solution, since the size of the slot is larger than that of the block, the decorative part can still slide the slot towards the base after the block is inserted into the slot. Therefore, during the installation process, excessive force may be applied or excessive sliding may occur. The end of the installation may be sleeved on the side of the base with a larger outer contour size, or the block may slide out of the slot and push against the inside of the decorative part outward, which may cause structural damage such as cracking and white lines on the decorative part. In this application, a limiting block is added to abut the end face of the installation end to prevent the decorative parts from sliding excessively, thereby improving the product yield and reducing the possibility of damage caused by misoperation during product disassembly and reassembly.

[0024] Optionally, the base has a positioning strip on the side facing the mounting end, and the mounting end has a positioning groove for the positioning strip to be inserted. The positioning groove has two parallel positioning surfaces, which are parallel to the fitting direction of the decorative piece. The two positioning surfaces fit and abut against the two sides of the positioning strip.

[0025] By adopting the above technical solution, the state of the decorative parts and the base after installation can be determined, thus preventing shaking between the decorative parts and the base after installation.

[0026] Optionally, the positioning groove has an inwardly closing guide surface at the opening facing the base.

[0027] By adopting the above technical solution, it is easy for the positioning block to slide into the positioning groove, which facilitates the installation of the base and decorative parts.

[0028] In summary, this application has at least the following beneficial effects: This application, through the design of the deformation port and the prying part, enables convenient contact between the snap-fit ​​connection between the decorative part and the base, facilitates easy disassembly and cleaning of debris entering the interior of the decorative part, minimizes the possibility of damage to the decorative part and the base during disassembly, and allows the disassembled parts to be reused.

Detailed Implementation

[0030] As attached Figure 1 and attached Figure 2 As shown, an automatic trunk switch for automobiles includes a switch body 1, a base 2, a key cover 3, an elastic support 4, a key cap 5, and a decorative component.

[0031] As attached Figure 2 As shown, the switch body 1 is an electrical component, which includes a base 11 and a trigger rod 12 slidably connected to the center of the base 11. The base 11 is rectangular and contains circuit components such as contacts.

[0032] When the trigger rod 12 is pressed and slides into the base 11, it can push the internal electrical contacts to connect the circuit and realize the transmission of electrical signals.

[0033] The base 2 has openings at both ends and is fitted onto the outside of the base 11. The base 2 is divided into a base body 21 and an insert body 22 along the opening direction. Both the base body 21 and the insert body 22 are square rings. The inner side of the base body 21 is engaged with the outer side of the base 11.

[0034] As attached Figure 3 As shown, each of the four outer surfaces of the insert 22 has a raised locking block 221. The number of locking blocks 221 on each side is related to the length of the side; here, the number of locking blocks 221 on the four outer surfaces of the insert 22 is two, one, two, and one, respectively. The side of the locking block 221 facing away from the outer surface of the insert 22 is a slope, which slopes outward from the insert 22 toward the base 21.

[0035] Furthermore, the outer contour dimension of the base 21 is larger than that of the insert 22, so the base 21 has an exposed end face facing the insert 22. The end face of the base 21 facing the insert 22 has a limit block 211 and a positioning strip 212.

[0036] The number of limiting blocks 211 is equal to the number of locking blocks 221, and their distribution positions correspond one-to-one with those of locking blocks 221, located on the projection of locking blocks 221 onto the end face of the base 21. The side of the limiting block 211 facing the locking block 221 is parallel to the end face of the base 21 facing the insert 22.

[0037] The positioning strip 212 extends along the outer surface of the insert 22 from the end face of the base 21 facing the insert 22, and its extension direction is perpendicular to the end face of the base 21 facing the insert 22. The end of the positioning strip 212 away from the end face of the base 21 facing the insert 22 is wedge-shaped.

[0038] As attached Figure 2 As shown, the key cover 3 is in the shape of a cover, and its cover is snapped onto the end of the trigger rod 12 that protrudes from the base 11.

[0039] As attached Figure 2 and attached Figure 4 As shown, the elastic support 4 is a shell made of elastic material, which has the ability to deform under pressure. Here, it is made of rubber. The elastic support 4 is located between the key cover 3 and the base 2, on the end of the insert 22 facing away from the base 21.

[0040] One end of the elastic support 4 is vulcanized to wrap the outside of the key cover 3, and passes through the pre-reserved perforation on the outside of the key cover 3 during rubber injection. After the rubber cools, the elastic support 4 is fixed to the outside of the key cover 3.

[0041] The other end of the elastic support 4 also wraps around the end of the insert 22 away from the base 21, and passes through the perforation reserved at the end of the insert 22 during rubber injection. After the rubber cools, the elastic support 4 is fixed to the end of the insert 22.

[0042] As attached Figure 4 and attached Figure 5 As shown, the keycap 5 includes a pressing part 51 for a person to touch and press, and a connecting part 52 for fixing. The connecting part 52 is located on the side of the pressing part 51 facing the key cover 3, and the connecting part 52 covers the keycap 5 and is snapped and fixed to the keycap 5.

[0043] As attached Figure 6 As shown, the decorative part 6 is rectangular, hollow inside and open at both ends. Here, the two open ends of the decorative part 6 are respectively referred to as the installation end 61 and the display end 62.

[0044] As attached Figure 7 As shown, the mounting end 61 is fitted onto the outside of the insert 22 from one side of the keycap 5, so that one end of the switch body 1, the insert 22, the elastic support 4, the key cover 3, and the keycap 5 are all located inside the decorative part 6. The pressing part 51 is exposed from one side of the display end 62. The end face of the pressing part 51 is flush with the end face of the display end 62. There is a gap between the pressing part 51 and the inside of the opening on one side of the display end 62, so that the pressing part 51 can slide smoothly into the decorative part 6 when pressed, pushing the key cover 3 to press against the trigger rod 12.

[0045] As attached Figure 6 and attached Figure 7 As shown, at least one of the four sides of the mounting end 61 is the mounting side 611. The presence or absence of the mounting side 611 is related to the presence or absence of the locking block 221. The mounting side 611 and the locking block 221 are fixed to fix the decorative part 6 to the base 2. Here, all four sides of the mounting end 61 are the mounting side 611.

[0046] The mounting side 611 has a number of slots 612 equal to the number of slots 221 on the same side. The slots 612 penetrate the inside and outside of the mounting side 611 and are aligned with the slots 221. When the mounting end 61 is fitted onto the insert 22, the slots 612 move closer to the slots 221, and then the slots 221 slide into the slots 612 until the end face of the mounting end 61 abuts against the limiting block 211. The mounting end 61 is then fitted. At this time, the slots 221 and the groove wall of the slot 612 near the base 21 are in close contact.

[0047] On the other hand, the distance between the two side walls of the parallel mounting end 61 of the card slot 612 in the sleeve direction is greater than the thickness of the card block 221, so that there is a margin gap between the two side walls of the parallel mounting end 61 of the card slot 612 in the sleeve direction and the card block 221.

[0048] The mounting side 611 is also provided with a deformation opening 613 and a positioning groove 614. The deformation opening 613 is located on the end face of the mounting end 61, and the deformation opening 613 penetrates through the inside and outside of the mounting end 61, extending from the mounting end 61 to the display end 62. The number of positioning grooves 614 is equal to the number of positioning strips 212, and their positions are aligned one-to-one with the positioning strips 212. The positioning grooves 614 have inwardly inclined and closing guide surfaces 6141 on both sides of the groove opening facing the base 21.

[0049] The positioning groove 614 has two parallel groove walls that form positioning surfaces 6142, which are parallel to the fitting direction of the mounting end 61. The spacing between the positioning surfaces 6142 is equal to the width of the positioning strip 212. When the mounting end 61 is fitted onto the outside of the insert 22, the positioning strip 212 is inserted into the positioning groove 614, and both sides of the positioning strip 212 are in close contact with the positioning surfaces 6142.

[0050] As attached Figure 6 As shown, prying parts 7 are also fixed to the longer sides of the decorative part 6. The prying parts 7 are located between the mounting end 61 and the display end 62, and there are two prying parts 7 on each side.

[0051] As attached Figure 8 As shown, the prying component 7 includes a prying block 71 and a reinforcing block 72.

[0052] The prying block 71 has a fixed end 711 and a force-bearing end 712 at its two ends. The fixed end 711 is fixed to the outer surface of the decorative part 6. Here, the prying block 7 and the decorative part 6 are integrally injection molded, and the fixed end 711 is directly connected and fixed to the outer surface of the decorative part 6.

[0053] The force-bearing end 712 extends from the installation end 61 toward the display end 62, and is inclined away from the outer side of the decorative part 6 during the extension. The end face of the force-bearing end 712 is also equipped with anti-slip texture 7121.

[0054] The reinforcing block 72 is located at the root of the fixed end 711, and it connects the fixed end 711 and the outer side of the decorative part 6. The reinforcing block 72 is also integrally formed with the decorative part 6 and the prying block 71, thereby enhancing the bending resistance of the fixed end 711.

[0055] As attached Figure 2 and attached Figure 8As shown, the size of the reinforcing block 72 in the direction perpendicular to the fitting of the decorative piece 6 and the base 2 and in the tilting direction of the prying block 71 is smaller than that of the fixed end 711. The reinforcing block 72 is located on one side of the fixed end 711. Thus, the reinforcing block 72 strengthens the bending resistance of the fixed end 711 and provides sufficient space for the prying block 71 to bend and deform, making it easier to bend when the prying block 71 is under pressure, while not easily breaking due to bending.

[0056] The disassembly process for the automatic trunk release switch in this application is as follows: When liquids or debris enter the decorative part 6 through the gap between the display end 62 and the keycap 5, it will affect the normal pressing and rebound of the keycap 5, and the decorative part 6 and the base 2 need to be disassembled for cleaning. The thumb and forefinger of the human hand pinch the force-bearing end 712 of the pry bar 7 on both sides and bend the decorative part 6 as a whole; The prying component 7 pries the mounting side 611 of the decorative component 6, causing the mounting end 61 to bend and deform. The design of the deformation port 613 increases the amount of torsion that the end side of the mounting end 61 can be twisted without damaging the result, causing the locking block 221 to disengage from the slot 612. Therefore, by applying a pulling force away from the base 2 when prying the decorative part 6 as a whole, the decorative part 6 can be pulled off the insert 22, achieving quick disassembly and convenient maintenance. During this process, the structures of the decorative part 6 and the base 2 remain intact and can be reused. This solves the problem of difficulty in disassembling the base 2 and the decorative part 6 in the existing automatic trunk switch of automobiles, which easily leads to damage to the base 2 and the decorative part 6 during disassembly, making them unusable.

[0057] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of protection claimed by the present utility model, they are protected by patent law.
