[0002] With the increasing popularity of modern automobiles and the continuous improvement of their intelligent features, the operation of opening and closing vehicle tailgates is gradually becoming more electronic and user-friendly. The tailgate closing switch, as a crucial electronic component for automatically closing or signal-triggered tailgates, is widely used in various passenger and commercial vehicles. Existing tailgate closing switch devices generally include a mounting panel, operation buttons, a switch triggering mechanism, and a circuit board, enabling the input of opening or closing signals for the tailgate.

[0003] However, the following problems are common in existing technologies: First, the guide and limit structure design of the buttons is not reasonable enough, which can easily lead to jamming or excessive travel during pressing, affecting user experience and device lifespan. Second, the protection measures for the switch and circuit board are limited, with poor waterproof and dustproof performance, making it easy for moisture, dust and other impurities to enter, causing damage to electronic components or switch malfunction. Third, button reset mostly relies on mechanical springs or other components, which poses risks such as unreliable reset and easy damage, affecting the long-term stable operation of the switching device. In addition, the sealing and shock absorption effect between the device and the vehicle's sheet metal is poor. During frequent opening and closing and vehicle operation, the device is prone to loosening or falling off due to vibration, impact or external force, reducing the device's safety and service life. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a rear door closing switch device that can achieve reasonable structure, smooth operation, precise limit, excellent sealing and protection performance, and has good reset function and reliable installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A tailgate closing switch device includes a panel installed on the tailgate of a vehicle, a housing inserted into the panel, a base connected to one end of the housing, a circuit board component disposed inside the base, and a waterproof rubber pad disposed on the circuit board component, the waterproof rubber pad being used to protect the electronic components on the circuit board component. A button is movably connected to the other end of the housing. The button is used to trigger the switch on the circuit board component, and the button is automatically reset under the elastic force of the waterproof rubber pad.

[0006] Furthermore, panel foam pads are provided at both ends of the panel, and the panel foam pads are located between the panel and the vehicle sheet metal when the panel is installed.

[0007] Furthermore, both sides of the panel are provided with first buckles, and the first buckles are engaged with the vehicle sheet metal.

[0008] Furthermore, both sides of the panel are provided with first connecting seats for inserting the first buckle; A positioning groove is provided inside the first connecting seat; One end of the first buckle is provided with a plug plate, and the plug plate is provided with a positioning plate. When the first buckle is installed on the first connecting seat, the positioning plate is inserted into the positioning groove.

[0009] Furthermore, a through slot is provided on the panel, into which the outer casing is inserted; A second connecting seat is provided on both sides of the outer shell, and a second buckle is inserted into the second connecting seat; When the outer casing is inserted into the insertion slot, the second latch engages with the inner wall of the insertion slot.

[0010] Furthermore, a guide groove is provided on the outer side of the button; The interior of the outer casing is provided with guide strips; When the button is installed onto the housing, the guide bar is inserted into the guide groove; When the button is pressed, the guide bar slides within the guide groove.

[0011] Furthermore, a limiting window is provided through the button, and a limiting block is fixedly connected inside the housing, with the limiting block located inside the limiting window; The combination of limit windows and limit blocks is used to limit the range of motion of the buttons.

[0012] Furthermore, the circuit board component has a plug hole, and the waterproof rubber pad has a plug post that matches the plug hole.

[0013] Furthermore, the button has a pressure post inside, which corresponds to the touch switch on the waterproof rubber pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This utility model significantly improves the installation stability and shock resistance of the tailgate closing switch device by setting a plug-in structure and multiple buckle cooperation on the panel, effectively preventing the device from loosening or falling off due to long-term vehicle driving or frequent opening and closing, and ensuring the continuous and reliable operation of the tailgate opening and closing function.

[0015] By covering the surface of the circuit board components with a waterproof rubber pad and using plug-in pins and plug-in holes, the sealing and protection performance of electronic components is significantly improved, effectively preventing the intrusion of impurities such as moisture and dust. This solves the problem that the internal electronic components of switches are easily damaged by environmental factors in the existing technology, and extends the service life of the product.

[0016] By adopting a precise matching structure between the button guide groove and the housing guide strip, the button is guided linearly and anti-offset during the pressing process. This solves the problem of button jamming and offset in traditional switch devices, which leads to poor operation. At the same time, it improves the smoothness of operation and the durability of the structure.

[0017] By using a limit window and a limit block to limit the range of button movement, the risk of damage to internal components caused by excessive button travel is avoided, the reliability of the switching device in high-frequency use scenarios is improved, and maintenance costs caused by misoperation are reduced.

[0018] By precisely coordinating the pressure post inside the button with the touch switch on the waterproof rubber pad, high sensitivity and accuracy of signal triggering are achieved. The elasticity of the waterproof rubber pad enables the button to automatically reset, avoiding the defects of traditional mechanical springs that are easily damaged and unreliable in resetting, thus improving the overall durability of the device and the user experience.

[0019] The panel foam pad is placed between the panel and the vehicle sheet metal, which can effectively absorb vibration and buffer external impact, further improving the sealing and shock resistance of the entire device, solving the structural loosening and noise problems caused by vibration or impact, and ensuring the stable operation of the tailgate closing switch device under complex working conditions.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] See Figure 1-7 A tailgate closing switch device includes a panel 2 installed on the tailgate of a vehicle. The panel 2 is fixed to the mounting position of the tailgate using a precise positioning structure to ensure a good fit with the vehicle's sheet metal. A slot 21 is pre-set in the center of the panel 2, allowing the outer casing 5 to be accurately inserted into the slot 21, forming a tight, integrated connection and improving the overall device's shock resistance and protection performance. One end of the outer casing 5 is connected to a base 9, which houses a circuit board component 8. The circuit board component 8 serves as the control core of the switch device, handling signal input, processing, and output functions. A waterproof rubber pad 7 is fixedly installed on the surface of the circuit board component 8. The pad 7 not only covers and wraps all the electronic components on the circuit board component 8, but also effectively isolates external impurities such as moisture and dust through the elastic material properties, significantly improving the working reliability and service life of the electronic components. The other end of the outer shell 5 is movably connected to the button 1. The button 1 can generate axial movement when operated by the user and achieve precise sliding through the guide structure. The bottom of the button 1 is provided with a pressure post 11, which can directly act on the touch switch on the waterproof rubber pad 7 to accurately trigger the switch on the circuit board component 8. Under the action of the elasticity of the waterproof rubber pad 7, the button 1 is automatically reset, ensuring the continuous sensitive response and long-term stability of the switching device.

[0024] See Figure 1-2Panel 2 has panel foam pads 3 at both ends. The panel foam pads 3 are made of high elasticity and pressure-resistant material. When the panel 2 is installed on the vehicle's tailgate, the panel foam pads 3 are tightly clamped between the panel 2 and the vehicle's sheet metal, which plays an effective role in sealing, dustproofing and waterproofing. At the same time, it absorbs the slight displacement caused by vehicle vibration or external impact, thereby preventing the panel 2 from loosening or making noise due to long-term operation, and ensuring that the device can still maintain stability and reliability under complex working conditions.

[0025] See Figure 1-4 Both sides of the panel 2 are provided with first buckles 4. The first buckles 4 are designed with optimized structure to form a snap-fit ​​with the vehicle sheet metal, which improves the installation efficiency and stability of the panel 2. The surface of the first buckles 4 is thickened and treated with anti-detachment structure, so that the panel 2 can be disassembled and reassembled multiple times without affecting the fixing performance. This effectively prevents the loosening or falling off caused by long-term vehicle driving and frequent door opening and closing, and further improves the safety and reliability of the entire switch device.

[0026] See Figure 1-4 Both sides of the panel 2 are provided with first connecting seats 22 for inserting the first buckle 4; the first connecting seat 22 is provided with a positioning groove 221, the shape of which corresponds exactly to the positioning plate 411 on the first buckle 4 insertion plate 41; one end of the first buckle 4 is provided with an insertion plate 41, and the end of the insertion plate 41 is provided with a positioning plate 411; during assembly, when the first buckle 4 is inserted into the first connecting seat 22, the insertion plate 41 slides into the first connecting seat 22, and the positioning plate 411 automatically aligns and snaps into the positioning groove 221. The multi-point limiting method ensures that the position of the first buckle 4 inside the connecting seat 22 is fixed and reliable, which greatly improves the positioning accuracy and shock resistance of the panel 2 and the joint with the vehicle sheet metal, and avoids structural loosening caused by vehicle vibration or long-term use.

[0027] See Figure 1-5 A through-hole groove 21 is provided on the panel 2. The through-hole groove 21 provides space definition and guidance for the installation of the outer shell 5, ensuring that the outer shell 5 can be accurately aligned and inserted. A second connecting seat 51 is provided on both sides of the outer shell 5. The second connecting seat 51 provides a positional basis for the installation and limiting of the second buckle 6. The second buckle 6 is connected to the second connecting seat 51 by plugging. After assembly, the second buckle 6 is engaged on the inner wall of the through-hole groove 21, forming a secondary positioning with a tight structure, which further improves the connection strength and shock resistance between the outer shell 5 and the panel 2, and prevents loosening under dynamic conditions such as vehicle driving and door opening and closing.

[0028] See Figure 6The outer side of the button 1 is provided with a guide groove 13, which cooperates with the guide strip 53 inside the outer shell 5. The guide strip 53 is integrally formed inside the outer shell 5 and is inserted into the guide groove 13 on the outer side of the button 1 to realize the linear guidance of the button 1 when it is pressed axially. This ensures that the button 1 moves only along the specified trajectory when it is subjected to external force, effectively avoiding problems such as jamming, deviation, and wear of the button 1 during operation, and improving the smoothness of operation and structural life. See Figure 6 A limiting window 12 is provided through the button 1, and a limiting block 52 is fixedly connected inside the housing 5. The shape of the limiting block 52 matches the limiting window 12, and the limiting block 52 is located inside the limiting window 12. The cooperation between the limiting window 12 and the limiting block 52 can accurately limit the travel of the button 1, so that the button 1 is always within the safe travel range during the pressing process, preventing damage to internal components due to excessive operation, and ensuring the reliability and durability of the entire switching device under high frequency of use.

[0029] See Figure 7 The circuit board component 8 has insertion holes 81. The number and position of the insertion holes 81 are rationally designed according to the arrangement of electronic components to ensure accurate alignment during subsequent structural assembly. The waterproof rubber pad 7 is fixedly connected with insertion posts 71 that cooperate with the insertion holes 81. The insertion posts 71 are made of highly elastic waterproof material and can achieve a tight fit with the insertion holes 81 during assembly, further improving the sealing between the waterproof rubber pad 7 and the circuit board component 8, preventing moisture, dust and other impurities from penetrating into the interior of the circuit board component 8, providing comprehensive and effective protection for electronic components, and significantly improving the environmental adaptability of the product.

[0030] See Figure 6-7 The button 1 has a pressure post 11 inside. The pressure post 11 is located at the central axis of the lower end of the button 1. It can accurately act on the touch switch on the waterproof rubber pad 7 when the user presses it, ensuring the stability and accuracy of the signal trigger. The structure of the pressure post 11 is closely matched with the touch switch, which can effectively avoid misalignment or trigger failure, and improve the sensitivity and practical reliability of the switch device.

[0031] The working principle of this utility model is as follows: In actual use, the operation process and functions of this tailgate closing switch are as follows: When a user needs to close the vehicle's tailgate, they first press button 1. Button 1 has a guide groove 13 on its outer side. During installation, the guide strip 53 inside the housing 5 is inserted into the guide groove 13, providing precise guidance for the movement of button 1 and ensuring smooth, unobstructed pressing. During pressing, the limiting window 12 on button 1 cooperates with the limiting block 52 inside the housing 5 to effectively limit the range of motion of button 1, preventing the button from exceeding its predetermined travel and causing structural damage.

[0032] When button 1 is pressed, the pressure post 11 inside it pushes the touch switch on the waterproof rubber pad 7, triggering the switch on the circuit board component 8. The circuit board component 8 has a connector hole 81, and the waterproof rubber pad 7 has a corresponding connector post 71, thereby ensuring that the waterproof rubber pad 7 and the circuit board component 8 can be accurately aligned and effectively sealed, preventing moisture, dust and other impurities from entering the circuit board component 8, and providing reliable protection for the electronic components.

[0033] When button 1 is released, it will automatically spring back to its original position under the elastic force of the waterproof rubber pad 7, ensuring the long-term reliable use of the switch device.

[0034] The entire device's panel 2 is sealed and buffered between the panel sponge pad 3 and the vehicle sheet metal, effectively preventing loosening due to vibration or external force. The first buckles 4 on both sides of the panel 2 cooperate with the positioning groove 221 on the first connecting seat 22 through the insertion plate 41, realizing the quick positioning and stable installation of the panel 2 on the vehicle sheet metal. After the outer shell 5 is inserted into the insertion groove 21 of the panel 2, the second connecting seat 51 and the second buckle 6 cooperate to ensure that the connection between the outer shell 5 and the panel 2 is tight, preventing loosening during long-term use.

[0035] Through the synergistic effect of the above structures, this device achieves stable and sensitive triggering and automatic reset of the tailgate closing switch, while also possessing good waterproof, dustproof and shockproof performance, meeting the reliability and durability requirements of automotive tailgates in high-frequency use environments.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
