Technical Field
[0001] This utility model relates to the field of automotive door lock control technology, and in particular to a door unlocking switch device. Background Technology
[0002] Currently, electric vehicle door locks are widely used. Some electric vehicle door locks use a push-button door lock switch device integrated inside the door handle assembly to provide the unlocking signal. Users generate an unlocking signal by lightly touching the button panel of the switch device, achieving automatic unlocking. This process eliminates the need for users to forcefully pull the door handle's mechanical structure to unlock the door. However, the existing PCBA (Printed Circuit Board Assembly) of the door lock switch device integrated into the door handle assembly is a separate circuit board, requiring dust and water protection from the door handle assembly when mounted within it. For example... Figure 1 As shown, the switch circuit board 10 and the push-button switch 11 are located in the sealed space formed by the inner handle 22, the soft rubber structure 23 and the door handle cover 21, achieving dustproof and waterproof sealing. This solution, which relies on the door handle assembly to achieve push-button switch protection, requires customized waterproof and dustproof solutions for different door handle assemblies, lacking universality. Furthermore, existing methods generally seal the PCBA through processes such as laser welding of the housing. Since the switch and the door handle assembly are an integrated structure, if the unlocking switch is damaged, the entire door handle assembly needs to be replaced, resulting in high maintenance costs for users.
[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content
[0004] The purpose of this utility model is to provide a car door unlocking switch device, which achieves waterproof and dustproof protection through modular encapsulation of the switch, eliminating the need for protective modifications to the door handle assembly.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0025] This utility model relates to a vehicle door unlocking switch device. For example... Figures 2-6As shown, the door unlocking switch device of this embodiment includes: a switch circuit board 10, a protective housing 12, and a mounting structure.
[0026] The switch circuit board 10 is provided with at least one push-button switch 11, which provides a door lock unlocking signal when triggered.
[0027] The protective housing 12 has a sealed accommodating cavity, in which the switch circuit board 10 is disposed, thereby providing waterproof and dustproof protection for the switch circuit board 10. This eliminates the need for waterproof and dustproof modifications to the door handle assembly, saving the cost of custom development and design of waterproof and dustproof door handle assemblies. It also eliminates the need for complex welding processes, and the door unlocking switch device is easy to disassemble, repair, or replace from the door handle assembly. Therefore, there is no need to replace the door handle assembly during maintenance, which can significantly reduce maintenance costs.
[0028] The mounting structure is set on the protective housing 12 and is used to install the door unlocking switch device inside the door handle assembly with the push-button switch 11 facing the inside of the door handle. After the door unlocking switch device is installed inside the door handle assembly, when the user pulls the door handle, he / she lightly touches the button panel on the inside of the door handle to trigger the push-button switch 11, thereby generating a door lock unlocking signal. After receiving the unlocking signal, the electric door lock of the vehicle unlocks the door, making door unlocking convenient and effortless.
[0029] The protective housing 12 may include a protective cover 121 and at least one flexible button cover 13, with at least one button switch 11 located inside the flexible button cover 13. The bottom of the protective cover 121 is open, and flexible sealant 122 is poured into the protective cover 121 to form a sealed accommodating cavity. After the flexible sealant 122 is poured in, it is cured together with the protective cover 121, giving the protective housing 12 good waterproof and dustproof capabilities.
[0030] There are two flexible button covers 13 and two button switches 11, and they are spaced apart along the length of the protective cover 121. By setting two flexible buttons 11, multiple points can be triggered, ensuring the success rate of button switch 11 triggering, so that the button switch can be triggered when the door handle is pulled by hands of different sizes. It is understood that there can also be one or more flexible buttons 11. This embodiment does not impose a specific limitation on the number of flexible buttons and flexible button covers.
[0031] The protective cover 121 and at least one flexible button cover 13 can be a single piece, thereby giving the protective housing 12 good waterproof and dustproof performance. Specifically, the protective cover 121 and the flexible button cover 13 can be integrally molded using processes such as two-color injection molding or double injection molding. Two-color injection molding or double injection molding processes are mature and low in cost.
[0032] The mounting structure may include at least one L-shaped positioning structure 14 disposed on the protective cover 121 and a screw post 15 disposed at one end of the protective cover 121 and arranged along the length of the protective cover 121, the screw post 15 having a screw hole. By way of example and not limitation, there may be two L-shaped positioning structures 14, parallel to each other and located on one side of at least one flexible button cover 13. After the door unlocking switch device is positioned on the frame of the door handle assembly by the two L-shaped positioning structures, the door unlocking switch device can be fixedly installed in the door handle assembly by screwing screws into the screw holes of the screw post 15. Installation and removal are very convenient. It is understood that other simple and convenient structures suitable for fixing the door unlocking switch device in the door handle assembly can also be used, without excessive limitations. The switch circuit board 10 has a signal harness 16, which can be snapped into the protective cover 121. The other end of the signal harness 16 can be connected to the door control device, and the signal of the switch circuit board 10 is sent to the door lock through the signal harness 16.
[0033] In some examples, a capacitive sensor (not shown) may also be integrated on the switch circuit board 10. This capacitive sensor, when triggered, generates a door lock control signal, such as a door lock locking signal. Specifically, the sensing area of the capacitive sensor may be located at a preset position corresponding to the outside of the door handle assembly, and the sensing area has a conductive structure for conductive connection with the door handle assembly. The sensing area of the capacitive sensor can be the position touched by the thumb when pulling the door handle. When locking the car, the user can touch the capacitive sensing area, triggering the sensor to send a locking signal to the electric door lock. The conductive structure can be conductive foam, which conductively connects the capacitive sensor and the door handle assembly, allowing the capacitive sensor to better sense the capacitance change after a hand touches it. Due to the conductivity of the human body, when a hand touches the sensing area of the capacitive sensor, the capacitance of the sensor changes. Based on the amount of capacitance change and the capacitance change threshold, it can be determined whether a hand has touched the sensing area. The capacitive sensor can provide a locking signal to the door lock, facilitating locking the car when leaving. Capacitive sensors are widely used in smart devices, and their implementation is well known to those skilled in the art and will not be described in detail here.
[0034] In some examples, the switch circuit board 10 may also integrate an NFC (Near Field Communication) module, which is used to generate a door lock control signal when triggered. The NFC module can be an NFC card reader; when a user swipes an NFC card (i.e., an NFC tag), the switch circuit board 10 can generate an unlock or lock signal. The implementation of the NFC module is well known to those skilled in the art and will not be described in detail here.
[0035] In some cases, the switch circuit board 10 may also integrate a Bluetooth Low Energy (BLE) module for the digital key. The BLE module can serve as a Bluetooth positioning anchor point for the digital key system. It should be noted that when the switch circuit board integrates a push-button switch, a capacitive sensor, and an NFC module, each module can be connected to the door lock control unit via independent cables.
[0036] The positive and progressive effects of the door unlocking switch device of this utility model embodiment are as follows:
[0037] 1. Protective
[0038] In the prior art, the electronic push-button door unlocking switch located inside the door handle is generally a separate PCBA, which is assembled inside the door handle assembly and requires the door handle assembly to provide a waterproof and dustproof protective structure.
[0039] The door unlocking switch device of this utility model has dustproof and waterproof capabilities, so that the door handle assembly does not need to be designed to be dustproof and waterproof. This avoids the limitation of the application of button electronic switch technology caused by the need to design an additional waterproof structure for the door handle assembly, and removes the obstacles to the application of electronic button unlocking switches on the inside of the door handle.
[0040] 2. Universality
[0041] In the existing technology, the electronic push-button door unlocking switch is a separate PCBA. If it is to be universal for other models, the door handle assembly needs to be designed with a matching structure with the PCBA, or the PCBA needs to be adjusted in terms of size for different models.
[0042] The door unlocking switch device of this utility model is an independent assembly, small in size, highly versatile, and adaptable to door handle assemblies of different car models and styles. This reduces customized development work for different car models, reduces costs associated with product development, experimentation, and the universality of production fixtures, and significantly shortens the product development cycle.
[0043] 3. Modular design
[0044] In the existing technology, the electronic push-button door unlocking switch is a separate PCBA. If additional functions are added, the door handle assembly that works with the PCBA needs to be significantly modified, making it difficult to adapt to the trend of diversified door unlocking and locking methods.
[0045] The door unlocking switch device of this utility model adopts a modular design. On the door unlocking switch assembly, capacitive induction unlocking function, NFC unlocking function and BLE function can be added to the existing assembly according to the system solution requirements, which effectively improves the product competitiveness.
[0046] 4. Maintainability
[0047] In the existing technology, the electronic button-type door unlocking switch on the inside of the door handle is integrated with the door handle assembly. It is sealed and protected by laser welding, potting and other methods, and is non-removable. As a result, if the unlocking switch button or PCBA fails, the user needs to replace the entire door handle assembly, which results in high maintenance costs.
[0048] The door unlocking switch device of this utility model is an independent assembly. If it fails or requires hardware upgrade and maintenance, only the electronic button door unlocking switch assembly needs to be replaced, without replacing the entire door handle assembly. This reduces the user's maintenance costs and minimizes resource waste.
[0049] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
