Description

Technical Field

[0001] This utility model relates to the field of automotive trunk switch technology, specifically to a protective structure for an automotive trunk push-button switch. Background Technology

[0002] The trunk release switch controls the opening and closing of the vehicle's trunk. The switch consists of a housing and a rubber pad mounted on the housing. The trunk release switch is located inside the housing and the rubber pad. Users press the rubber pad to activate the trunk release switch and control the opening and closing of the trunk. During installation, the housing and rubber pad need to be manufactured separately and then bonded together. This manufacturing method is not only inefficient, but also results in a small gap between the rubber pad and the housing, causing adhesive to easily seep out when applied, thus compromising the cleanliness of the surfaces between the housing and the rubber pad. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect of glue easily seeping out during manufacturing in the prior art, thereby providing a protective structure for the car trunk push switch that has high manufacturing efficiency and can prevent glue overflow during the manufacturing process.

[0004] Therefore, this utility model provides a protective structure for a push-button switch in a car trunk, including a housing and an elastic pad injection molded with the housing. The housing is provided with a groove for the elastic pad to be embedded in. The elastic pad is coated with glue, and a space is left between the elastic pad and the groove to prevent glue from overflowing.

[0005] Furthermore: a pressing block is provided inside the housing, and a guide mechanism is provided between the pressing block and the side wall of the housing to guide the pressing block to move up and down. A clearance groove for mounting the circuit board is provided inside the pressing block.

[0006] Furthermore, the guiding mechanism includes a guide post disposed on one side of the pressing block or the side wall of the housing, and a guide groove disposed on the other side that can be adapted to the guide post.

[0007] Furthermore, a pressing post is provided below the pressing block to contact the micro switch on the circuit board.

[0008] Furthermore, the pressing column is arranged in a cross shape.

[0009] Furthermore: a connecting shell is provided below the housing, and a snap-fit ​​structure is provided between the connecting shell and the housing. The snap-fit ​​structure includes a snap-fit ​​block provided on one side of the housing or the connecting shell and a snap-fit ​​groove provided on the other side and adapted to the snap-fit ​​block. A guide slope is provided on the side of the snap-fit ​​block to guide the snap-fit ​​block into the snap-fit ​​groove.

[0010] Furthermore: an extension ring is provided at the connecting shell, and an annular groove is provided on the shell for the extension ring to be inserted into, and the extension ring can abut against the inside of the annular groove.

[0011] The technical solution of this utility model has the following advantages:

[0012] 1. The protective structure for a push-button switch in a car trunk provided by this utility model involves applying glue to the edge of an elastic pad and allowing it to dry during production and manufacturing. The glued elastic pad is then placed on a mold, and the housing and elastic pad are injection molded together. Heat is generated during the injection molding process, which melts the glue, thus bonding the housing and elastic pad together. To prevent glue leakage, a gap is left between the elastic pad and the groove. Therefore, when the glue melts, it fills this gap. Since the glue is pre-applied to the elastic pad and is applied in a measured amount, it prevents overflow during the injection molding process. This design is superior to existing technologies, as it allows for rapid injection molding of the housing and elastic pad, simplifying the production process. The residual heat during injection molding melts the glue, resulting in a tighter bond between the housing and elastic pad.

[0013] 2. The present invention provides a protective structure for a push-button switch for a car trunk. A push-button block is provided inside the housing, and a circuit board is provided below the push-button block. The circuit board has a micro switch. When the user presses the elastic pad with his hand, the elastic pad will drive the push-button block to move towards the side closer to the micro switch. The push-button block will contact the micro switch, thereby opening the trunk door. Attached Figure Description

[0026] Example

[0027] This embodiment provides a protective structure for a push-button switch in a car trunk, including a housing 1 and an elastic pad 2 injection molded with the housing 1. The housing 1 is provided with a groove 11 for the elastic pad 2 to be embedded. The elastic pad 2 is coated with glue, and a space is left between the elastic pad 2 and the groove 11 to prevent glue from overflowing.

[0028] The specific improvements mentioned above are as follows: Figure 1 and Figure 2 As shown, during production and manufacturing, glue needs to be applied to the edge of the elastic pad 2 and allowed to dry. Then, the glued elastic pad 2 is placed on the mold, and the shell 1 and the elastic pad 2 are injection molded together. During the injection molding process, heat is generated, which melts the glue, thus bonding the shell 1 and the elastic pad 2 together. At the same time, to prevent glue leakage, a certain gap is left between the elastic pad 2 and the groove 11. Therefore, when the glue melts, it can fill the gap. Since the glue is pre-applied to the elastic pad 2 and the glue is measured in a fixed amount, it can be ensured that the glue will not overflow during the injection molding process. This is superior to the existing technology, as it can quickly mold the shell 1 and the elastic pad 2, simplifying the production steps. The residual heat during the injection molding process melts the glue, making the shell 1 and the elastic pad 2 more tightly connected.

[0029] Based on the above embodiments: a pressing block 3 is provided inside the housing 1, and a guide mechanism 4 for guiding the pressing block 3 to move up and down is provided between the pressing block 3 and the side wall of the housing 1. An avoidance groove 31 for mounting the circuit board is provided inside the pressing block 3.

[0030] The specific improvements mentioned above are as follows: Figure 2 and Figure 3 As shown, a pressing block 3 is provided inside the housing 1, and a circuit board is provided below the pressing block 3.

[0032] The specific improvements mentioned above are as follows: Figure 4As shown, the guide mechanism 4 includes a guide post 41 disposed on the housing 1 and a guide groove 42 disposed on the pressing block 3. The guide groove 42 has an opening for the guide post 41 to be inserted. Through the cooperation of the guide post 41 and the guide groove 42, the pressing block 3 can be effectively guided to move up and down, thereby smoothly triggering the trunk to open or close.

[0033] Based on the above embodiments: a pressing post 5 is provided below the pressing block 3 to contact the micro switch on the circuit board.

[0034] Based on the above embodiments: the pressing column 5 is arranged in a "+" shape.

[0035] The specific improvements mentioned above are as follows: Figure 3 and Figure 4 As shown, a pressing post 5 with a cross shape is set below the pressing block 3. The pressing post 5 contacts the micro switch. The cross shape structure can ensure that the pressing post 5 makes more stable contact with the micro switch.

[0036] Based on the above embodiments: a connecting shell 6 is provided below the housing 1, and a snap-fit ​​structure 7 is provided between the connecting shell 6 and the housing 1. The snap-fit ​​structure 7 includes a snap-fit ​​block 71 provided on one of the housing 1 or the connecting shell 6 and a snap-fit ​​groove 72 provided on the other and adapted to the snap-fit ​​block 71. A guide slope 73 is provided on the side of the snap-fit ​​block 71 to guide the snap-fit ​​block 71 into the snap-fit ​​groove 72.

[0037] Based on the above embodiments: an extension ring 8 is provided at the connecting shell 6, and an annular groove 81 is provided on the shell 1 for the extension ring 8 to be inserted, and the extension ring 8 can abut against the inside of the annular groove 81.

[0038] The specific improvements mentioned above are as follows: Figure 2 and Figure 5 As shown, a connecting shell 6 is provided below the housing 1, and a snap-fit ​​structure 7 is provided between the connecting shell 6 and the housing 1. The wires on the circuit board can be gathered at the connecting shell 6. The connecting shell 6 is provided with pins for interlocking with other plug-in components. In this embodiment, the connection method between the circuit board and the pins is existing technology and will not be described here. Through the setting of the connecting shell 6, the connecting shell 6 can be quickly connected to the housing 1 and can prevent the circuit board from being exposed. When the connecting shell 6 is inserted into the housing 1, the extension ring 8 at the connecting shell 6 will be inserted into the annular groove 81 and abut against the annular groove 81. Through the cooperation of the extension ring 8 and the annular groove 81, the housing 1 and the connecting shell 6 can be quickly connected. Through the cooperation of the snap-fit ​​block 71 and the snap-fit ​​groove 72, the connecting shell 6 can be fixed inside the housing 1. Through the setting of the guide slope 73, the snap-fit ​​block 71 can be effectively guided to insert into the snap-fit ​​groove 72.
