Description

Technical Field

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

[0002] Cars are becoming increasingly common in people's lives. Every car has a trunk, and the trunk button switch is located not only on the car key but also inside the car. The trunk can be opened by pressing the switch inside the car.

[0003] Currently, push-button switches open the trunk of a car simply by pressing them. However, since there is no protection for the buttons while the car is in motion, if someone accidentally touches them, the trunk will open, causing items inside to be thrown out of the vehicle. This increases the risk of accidents and reduces safety during use. Therefore, we propose a push-button switch for car trunks to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background section, the present invention provides a push-button switch for a car trunk.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] A push-button switch for a car trunk includes: a housing, four telescopic mechanisms on the top of the housing, four annular grooves on the top of the housing, protective mechanisms on the four telescopic mechanisms, a base connected to the bottom of the inner wall of the housing, a PCBA connected to the top of the base, an inner waterproof sleeve fitted on the top of the PCBA, a positioning sleeve connected inside the housing with its bottom fitting against the top of the inner waterproof sleeve, a slider connected inside the positioning sleeve, an outer waterproof sleeve connected to the top of the slider and connected to the positioning sleeve, and a button connected to the top of the outer waterproof sleeve.

[0007] As a further embodiment of this utility model: the telescopic mechanism includes a hollow cylinder, a limiting plate, a sliding rod, and a spring. The hollow cylinder is connected to the top of the outer shell. The limiting plate and the sliding rod are both slidably connected to the inner surface of the hollow cylinder, and the bottom end of the sliding rod is connected to the top of the limiting plate. The top end of the sliding rod extends to the top of the hollow cylinder, and the spring is connected between the bottom of the limiting plate and the bottom of the inner wall of the hollow cylinder.

[0008] As a further embodiment of this utility model: the protective mechanism includes a transparent shell, a handle and four rubber pads. The transparent shell is connected to the top of the sliding rod, and the bottom of the transparent shell has four circular grooves. The sliding rod is located inside one of the circular grooves, and the outer surface of the transparent shell has a slot. The handle is connected to the top of the transparent shell, and the four rubber pads are all connected to the bottom of the transparent shell.

[0009] As a further improvement of this utility model, the four rubber gaskets are respectively movably inserted into the interior of the four annular grooves.

[0010] As a further embodiment of this utility model: the protective mechanism includes a sealing ring and a retaining strip, the sealing ring being sleeved on the outer surface of the transparent shell, and the retaining strip being connected to the inner surface of the sealing ring.

[0011] As a further improvement of this utility model, the card strip is embedded in the inner surface of the card slot.

[0012] As a further improvement of this utility model: mounting plates are connected to both the front and back of the housing, and a wire harness sheath is connected to the outer surface of the housing.

[0013] By adopting the above structure, this utility model has the following advantages compared with the prior art:

[0014] 1. In this utility model, through the cooperation of the hollow cylinder, limiting plate, sliding rod, spring, transparent shell, and handle, the handle can be pulled to lift the transparent shell and remove the obstruction of the button. At this time, the button can be pressed. When the button is not in use, the handle is released, and the spring resets and drives the limiting plate to slide down, so that the sliding rod drives the transparent shell to fit against the top of the outer shell, thereby completing the protection of the button. This utility model allows the button to be easily unobstructed when it is to be used, thus facilitating its use. When not in use, it can be covered to prevent accidental activation of the trunk, thereby improving the safety factor during use.

[0015] 2. In this utility model, through the cooperation between the inner waterproof sleeve, the outer waterproof sleeve, the sealing ring, and the retaining strip, the inner waterproof sleeve directly waterproofs the PCBA, the outer waterproof sleeve waterproofs the top of the outer shell, and the retaining strip waterproofs the top of the outer shell and the gaps in the transparent shell. This utility model can provide triple sealing for the PCBA, thereby achieving a good waterproof effect. At the same time, the sealing ring can be easily disassembled through the retaining strip, making it convenient for replacement and maintenance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1-5 In this embodiment of the utility model, a push-button switch for a car trunk includes: a housing 1, four telescopic mechanisms 2 on the top of the housing 1, four annular grooves on the top of the housing 1, protective mechanisms 3 on the four telescopic mechanisms 2, protective mechanisms 4 on the protective mechanisms 3, a base 5 connected to the bottom of the inner wall of the housing 1, a PCBA 6 connected to the top of the base 5, an inner waterproof sleeve 7 fitted on the top of the PCBA 6, a positioning sleeve 8 connected to the inside of the housing 1, with the bottom of the positioning sleeve 8 fitting against the top of the inner waterproof sleeve 7, a slider 9 connected to the inside of the positioning sleeve 8, an outer waterproof sleeve 10 connected to the top of the slider 9, and the outer waterproof sleeve 10 connected to the positioning sleeve 8, and a button 11 connected to the top of the outer waterproof sleeve 10.

[0025] Specifically, when button 11 is needed, pulling the protective mechanism 3 causes the four telescopic mechanisms 2 to extend. At this time, the protective mechanism 3 will no longer block the top of the outer shell 1, allowing button 11 to be pressed. Releasing the protective mechanism 3 will cause the four telescopic mechanisms 2 to reset, causing the protective mechanism 3 to descend and fit against the top of the outer shell 1, thus completing the blocking of button 11. Pressing button 11 will drive the slider 9 to press the micro switch on PCBA6, realizing the circuit switching and completing the opening and closing of the trunk. The positioning sleeve 8 is installed on the inner surface of the outer shell 1 by a snap-fit ​​and presses the inner waterproof sleeve 7, so that the inner waterproof sleeve 7 can play a preliminary waterproof role for PCBA6. The outer waterproof sleeve 10 is installed on the positioning sleeve 8 to waterproof the top of the outer shell 1. Finally, the protective mechanism 4 fits into the gap between the outer shell 1 and the protective mechanism 3 to seal and block, thereby preventing rainwater from seeping into the interior of the protective mechanism 3, thus further waterproofing PCBA6. Finally, the protective mechanism 4 can be removed from the protective mechanism 3 for easy replacement.

[0026] Example 2:

[0027] Please see Figures 2-4 In this embodiment of the present invention, the push-button switch for a car trunk includes a telescopic mechanism 2 comprising a hollow cylinder 201, a limiting plate 202, a sliding rod 203, and a spring 204. The hollow cylinder 201 is connected to the top of the outer shell 1. The limiting plate 202 and the sliding rod 203 are both slidably connected to the inner surface of the hollow cylinder 201, with the bottom end of the sliding rod 203 connected to the top of the limiting plate 202 and the top end of the sliding rod 203 extending to the top of the hollow cylinder 201. The spring 204 is connected to the bottom of the limiting plate 202 and the inner wall of the hollow cylinder 201. Between the bottoms, the protective mechanism 3 includes a transparent shell 301, a handle 302, and four rubber pads 303. The transparent shell 301 is connected to the top of the slide rod 203, and the bottom of the transparent shell 301 has four circular grooves. The slide rod 203 is located inside one of the circular grooves, and the outer surface of the transparent shell 301 has a slot. The handle 302 is connected to the top of the transparent shell 301, and the four rubber pads 303 are all connected to the bottom of the transparent shell 301. The four rubber pads 303 are respectively movably inserted into the four annular grooves.

[0028] Specifically, pulling the handle 302 causes the transparent shell 301 to rise. The transparent shell 301 then causes the slide rod 203 and the limiting plate 202 to slide upward on the inner surface of the hollow cylinder 201, and the spring 204 will be stretched. At this time, the handle 302 will no longer block the button 11, so the button 11 can be pressed. Releasing the handle 302 will cause the spring 204 to return to its original position, thereby causing the limiting plate 202 to slide downward on the inner surface of the hollow cylinder 201. The limiting plate 202 then causes the transparent shell 301 to move downward through the slide rod 203 and fit against the top of the outer shell 1. At the same time, the four rubber gaskets 303 will be inserted into the four annular grooves to buffer the force generated by the automatic contact between the transparent shell 301 and the outer shell 1. At this time, the transparent shell 301 can protect the button 11 and prevent accidental touch by personnel.

[0029] Example 3:

[0030] Please see Figures 1-5 In this embodiment of the utility model, the button switch for the trunk of a car has a protection mechanism 4 including a sealing ring 401 and a retaining strip 402. The sealing ring 401 is sleeved on the outer surface of the transparent shell 301, and the retaining strip 402 is connected to the inner surface of the sealing ring 401. The retaining strip 402 is embedded in the inner surface of the slot. Mounting plates are connected to both the front and back of the shell 1, and a wire harness sheath is connected to the outer surface of the shell 1.

[0031] Specifically, the positioning sleeve 8 is installed on the inner surface of the outer shell 1 by a snap-fit ​​and presses the inner waterproof sleeve 7, so that the inner waterproof sleeve 7 provides an initial seal for the PCBA6. The outer waterproof sleeve 10 is installed on the positioning sleeve 8 to waterproof the top of the outer shell 1, thereby sealing it again. Finally, when the transparent shell 301 is attached to the top of the outer shell 1, the sealing ring 401 will cover the gap between the top of the outer shell 1 and the bottom of the transparent shell 301, thereby sealing it again and preventing rainwater from seeping into the interior of the transparent shell 301. Finally, the sealing ring 401 can be removed from the slot by the clip 402 for easy replacement. The two mounting plates facilitate the fixed installation of the outer shell 1, and the wire harness sheath facilitates the protection of the wiring.

[0032] The working principle of this utility model is as follows: When the trunk needs to be opened, the operator pulls the handle 302, which causes the transparent shell 301 to rise. As the transparent shell 301 rises, it causes the sliding rod 203 and the limiting plate 202 to slide upwards on the inner surface of the hollow cylinder 201, and the spring 204 is stretched. At this time, the handle 302 no longer obstructs the button 11. Pressing the button 11 causes the slider 9 to press the micro switch on the PCBA6, thereby opening and closing the circuit and completing the opening and closing of the trunk. When not in use, releasing the handle 302 causes the spring 204 to return to its original position, causing the limiting plate 202 to slide downwards on the inner surface of the hollow cylinder 201. This causes the limiting plate 202 to move the transparent shell 301 downwards via the sliding rod 203, thus fitting it against the top of the outer shell 1. Four rubber gaskets 303 will be inserted into four annular grooves to reduce the force generated by the collision between the transparent shell 301 and the outer shell 1. At this time, the button 11 can be protected by the transparent shell 301 to avoid accidental touch. The positioning sleeve 8 is installed on the inner surface of the outer shell 1 by a snap-fit ​​and presses the inner waterproof sleeve 7, so that the inner waterproof sleeve 7 can play a preliminary waterproof role for the PCBA6. The outer waterproof sleeve 10 is installed on the positioning sleeve 8 to waterproof the top of the outer shell 1. Finally, the transparent shell 301 is attached to the top of the outer shell 1, and the bottom of the sealing ring 401 will be attached to the top of the outer shell 1, thereby blocking the gap between the top of the outer shell 1 and the bottom of the transparent shell 301, thus preventing rainwater from seeping into the interior of the transparent shell 301. Finally, the sealing ring 401 can be removed by removing the clip 402 from the slot, which makes it easy to replace.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
