[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] First Embodiment

[0029] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a keyless entry handle with a PCB circuit board structure as the touch area provided by this utility model; Figure 2 for Figure 1 The diagram shows the external handle bracket structure. Figure 3 for Figure 1 The diagram shows a cross-sectional structure. Figure 4 for Figure 1 The diagram shows a top view of the PCBA assembly. A keyless entry handle with a PCB circuit board structure as the touch area includes: an outer handle housing 1;

[0030] An outer handle bracket 6 is disposed on the inner side of the outer handle housing 1;

[0031] Switch bracket 2, which is disposed on the inner side of the outer handle bracket 6;

[0032] PCBA assembly 3 is disposed on the inner side of the switch bracket 2. The top of the PCBA assembly 3 is provided with a sensing copper sheet area 33, and the bottom of the PCBA assembly 3 is provided with sealant 4. The sealant 4 is disposed on the inner side of the switch bracket 2.

[0033] The top of the outer handle housing 1 is provided with a touch area 11.

[0034] A gasket 5 is provided on the top of the switch bracket 2.

[0035] PCBA assembly 3 is assembled inside switch bracket 2 and sealed with sealant 4. Switch bracket 2 is assembled on outer handle bracket 6. After outer handle shell 1 and outer handle bracket 6 are fastened together, switch bracket 2, PCBA assembly 3 and sealant 4 are completely fixed. A gasket 5 is provided between switch bracket 2 and outer handle shell 1 to ensure that there is no gap between the upper sensing copper plate area 33 of PCBA assembly 3 and the upper touch area 11 of outer handle shell 1, and to ensure that there is no capacitance change when the switch is not touched. When the user touches the touch area 11 on outer handle shell 1, the switch generates an electrical signal due to capacitance change, thereby realizing the opening and closing of the switch.

[0036] The working principle of the keyless entry handle with a PCB circuit board structure for the touch area provided by this utility model is as follows:

[0037] When a user's finger touches the touch area 11 on the top of the outer handle shell 1, the human body changes the capacitance value around the sensing copper plate area 33 on the PCBA assembly 3 below the touch area 11. After detecting this capacitance change, the PCBA assembly 3 converts it into an electrical signal, thereby controlling the opening or closing of the vehicle door lock to realize the keyless entry function. During this process, the sealant 4 prevents external moisture, dust and other impurities from entering the PCBA assembly 3, protecting its normal operation; the gasket 5 ensures a tight fit between the sensing copper plate area 33 and the touch area 11, avoiding unstable sensing or false triggering caused by gaps.

[0038] Compared with related technologies, the keyless entry handle with a PCB circuit board structure for the touch area provided by this utility model has the following advantages:

[0039] By eliminating the need for openings on the surface of the outer handle housing 1 to set buttons, appearance defects such as weld lines caused by openings are avoided, making the overall appearance of the outer handle more concise and beautiful, improving the visual effect of the product, and meeting customers' high requirements for the appearance of automotive parts.

[0040] The PCBA assembly 3, which adopts a PCB circuit board structure, has a higher stability and reliability in the way the sensing copper plate area 33 senses the change of capacitance compared with the traditional contact plate structure, reducing the probability of problems such as poor contact. At the same time, the sealing effect of the sealant 4 effectively improves the waterproof, dustproof and corrosion-resistant performance of the outer handle, ensuring normal use of the outer handle even in harsh environments and extending the service life of the product.

[0046] The outer handle housing 1 has a slot 9 at one end of its inner side, and the outer handle bracket 6 has a block 10 at the other end.

[0047] The card block 10 and the card slot 9 are compatible.

[0048] The working principle of the keyless entry handle with a PCB circuit board structure for the touch area provided by this utility model is as follows:

[0049] When installing the outer handle housing 1 and the outer handle bracket 6, first insert the locking block 10 at one end of the outer handle bracket 6 into the inner side of the slot 9, then insert the outer handle bracket 6 into the inner side of the outer handle housing 1, and align the first threaded hole 7 and the second threaded hole 8. Then, pass the locking screw through the first threaded hole 7 and the second threaded hole 8 to install the outer handle housing 1 and the outer handle bracket 6.

[0050] Compared with related technologies, the keyless entry handle with a PCB circuit board structure for the touch area provided by this utility model has the following advantages:

[0051] The first threaded hole 7, the second threaded hole 8, the slot 9 and the locking block 10 work together to allow the user to easily and quickly disassemble the outer handle shell 1 and the outer handle bracket 6 by simply threading the locking screw out from the inner side of the first threaded hole 7 and the second threaded hole 8.
