When the low-power wake-up PKE antenna circuit device is in use, to prevent coil breakage or solder joint detachment due to vibration, and indirectly reduce power consumption abnormalities caused by faults, the low-power wake-up PKE antenna circuit device needs overall protection. By bolting, a fixing plate is installed on the top surface of the mounting plate, and the bolts are threaded into the screw holes, so that the housing can be installed on the top surface of the mounting plate, providing overall protection for the low-power wake-up PKE antenna circuit device.

Description

Technical Field

[0001] This utility model relates to the field of PKE antenna technology, specifically to a low-power wake-up PKE antenna circuit structure. Background Technology

[0002] The PKE antenna is a key component in passive keyless entry systems, used for wireless signal reception and transmission. It enables contactless signal interaction between the device and the host through electromagnetic induction or radio frequency communication. PKE, or Passive Keyless Entry System, is widely used in automotive, smart home, and other scenarios. Its core principle is to achieve contactless communication between the device and the host through wireless radio frequency signals, allowing users to complete authentication and unlocking operations without actively pressing buttons.

[0003] Existing low-power wake-up PKE antenna circuits are often presented as a controller box, with the low-power wake-up PKE antenna circuit installed inside the box. For vibration scenarios such as automobiles, in order to prevent coil breakage or solder joint detachment caused by vibration, and indirectly reduce power consumption abnormalities caused by faults, the low-power wake-up PKE antenna circuit needs overall protection.

[0004] Therefore, we propose a low-power wake-up PKE antenna circuit structure that can provide overall protection for the low-power wake-up PKE antenna circuit, reduce its failure rate, and improve its performance. Utility Model Content

[0005] The purpose of this invention is to provide a low-power wake-up PKE antenna circuit structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-power wake-up PKE antenna circuit structure, including a mounting plate, a housing on the top surface of the mounting plate, a low-power wake-up PKE antenna circuit device inside the housing, and a processing component disposed outside the low-power wake-up PKE antenna circuit device. The processing component includes a protection component disposed outside the low-power component, and an auxiliary component disposed on the side of the protection component.

[0007] Preferably, the protective component includes a filling tube fixedly installed on the top surface of the box, a sealing plug sleeved inside the filling tube, a fixing plate fixedly installed on the outer wall of the box, a through hole opened inside the fixing plate, a bolt sleeved inside the through hole, and a screw hole opened on the top surface of the mounting plate.

[0008] Preferably, the auxiliary component includes an anti-stick layer fixedly installed on the inner wall of the box, a filter layer disposed on the outer side of the anti-stick layer, a moisture-proof layer fixedly installed on the outer wall of the filter layer, a reinforcing layer fixedly installed on the outer wall of the moisture-proof layer, a buffer layer fixedly installed on the outer wall of the reinforcing layer, and a durable layer fixedly installed on the outer wall of the buffer layer.

[0009] Preferably, the outer wall of the bolt is threaded into the inner hole of the bolt, and the outer wall of the bolt is threaded into the inner hole of the through hole. Under the constraint of the bolt, the box can be installed on the top surface of the mounting plate by means of the fixing plate.

[0010] Preferably, the end of the filling tube is connected to the top surface of the box, the outer wall of the sealing plug is threaded into the inside of the filling tube, and the box is sealed to the top surface of the mounting plate by bolts. When the sealing plug is opened, silicone gel is poured into the filling tube. The cured silicone gel can protect the low-power wake-up PKE antenna circuit device and prevent the low-power wake-up PKE antenna circuit device from being damaged by vibration. Under the limitation of the characteristics of silicone gel, it will not affect the signal transmission of the low-power wake-up PKE antenna circuit device.

[0011] Preferably, the anti-stick layer has an anti-stick coating on the side away from the box body, and the end of the anti-stick layer away from the filling tube is a sealing material. Under the restriction of the anti-stick layer, silicone gel can be prevented from adhering to the inner wall of the box body. Under the restriction of the anti-stick layer with a sealing material at the end, uncured silicone gel can be prevented from overflowing from the connection between the box body and the mounting plate.

[0012] Preferably, the enhancement layer is made of a signal enhancement material and the filter layer is made of a shielding material. Under the constraint of the enhancement layer, the signal transmission effect of the low-power wake-up PKE antenna circuit device can be enhanced. Under the constraint of the filter layer, the signal data of the non-low-power wake-up PKE antenna circuit device can be shielded, avoiding external signal interference to the use of the low-power wake-up PKE antenna circuit device, thereby improving the response speed of the low-power wake-up PKE antenna circuit device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The low-power wake-up PKE antenna circuit structure consists of a protection component. When the low-power wake-up PKE antenna circuit device is in use, to prevent coil breakage or solder joint detachment due to vibration, and indirectly reduce power consumption abnormalities caused by faults, the entire low-power wake-up PKE antenna circuit device needs overall protection. A fixing plate is installed on the top surface of the mounting plate using bolts. By threading the bolts into the screw holes, the entire housing can be installed on the top surface of the mounting plate, providing overall protection for the low-power wake-up PKE antenna circuit device. At this point, the sealing bolt is opened, and silicone gel is poured into the housing. After curing, it becomes a gel-like solid. Silicone gel has high light transmittance and is suitable for low-power... The encapsulated protection for low-power wake-up PKE antenna circuit devices offers strong weather resistance, excellent waterproof and moisture-proof performance, and no shrinkage during the curing process, thus eliminating compressive stress on the devices. When maintenance of low-power wake-up PKE antenna circuit devices is required, the bolts can be removed, and with the anti-stick layer, the cured silicone gel can be prevented from adhering to the inner wall of the enclosure. At this point, it can be easily cut or peeled off with tools. Due to the properties of the silicone gel, it does not stick to the surface, and the peeling is smooth, posing no risk of damage to the wire body or precision chips in the low-power wake-up PKE antenna circuit devices. This structure can provide overall protection for low-power wake-up PKE antenna circuit devices, preventing them from malfunctioning due to vibration damage.

[0015] 2. The low-power wake-up PKE antenna circuit structure consists of auxiliary components. Under the protection and restriction of the housing for the low-power wake-up PKE antenna circuit device, to prevent foreign objects from damaging the housing, the wear and corrosion resistance of the housing can be improved under the restriction of the toughness layer; under the restriction of the buffer layer, external forces can be buffered, preventing the housing from directly transmitting external forces to the low-power wake-up PKE antenna circuit device; under the restriction of the reinforcement layer, the signal transmission of the low-power wake-up PKE antenna circuit device can be enhanced; under the restriction of the moisture-proof layer, external moisture can be prevented from damaging the low-power wake-up PKE antenna circuit device; under the restriction of the filter layer, external cluttered signals can be shielded, making the low-power wake-up PKE antenna circuit device respond to signals more quickly; under the restriction of the anti-adhesion layer, cured silicone gel can be prevented from adhering to the inner wall of the housing.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the low-power wake-up PKE antenna circuit structure provided by this utility model is as follows: Figures 1 to 6 As shown: A low-power wake-up PKE antenna circuit structure, including mounting plate 1;

[0025] The top surface of mounting plate 1 is provided with box 2;

[0026] The box 2 contains a low-power wake-up PKE antenna circuit device 3;

[0027] The processing component 4 is located outside the PKE antenna circuit device 3 for low-power wake-up. The processing component 4 includes a protection component 41 located outside the low-power 3. The protection component 41 includes a filling tube 411 fixedly installed on the top surface of the box 2. A sealing plug 412 is sleeved inside the filling tube 411. A fixing plate 413 is fixedly installed on the outer wall of the box 2. A through hole 414 is opened inside the fixing plate 413. A bolt 415 is sleeved inside the through hole 414. A screw hole 416 is opened on the top surface of the mounting plate 1.

[0028] In this embodiment, when the low-power wake-up PKE antenna circuit device 3 is in use, to prevent coil breakage or solder joint detachment due to vibration, and indirectly reduce power consumption abnormalities caused by faults, the low-power wake-up PKE antenna circuit device 3 needs overall protection. Using bolts 415, the fixing plate 413 is installed on the top surface of the mounting plate 1. The bolts 415 are threaded into the screw holes 416, thus installing the entire housing 2 on the top surface of the mounting plate 1 and providing overall protection for the low-power wake-up PKE antenna circuit device 3. At this time, the sealing bolt 412 is opened, and silicone gel is poured into the housing 2. After it solidifies, it becomes a gel-like solid. The silicone gel has high light transmittance and is suitable for protecting the low-power wake-up PKE antenna circuit device 3. The encapsulated protection of the low-power PKE antenna circuit device 3 provides strong weather resistance, excellent waterproof and moisture-proof performance, and no shrinkage during the curing process, thus avoiding compressive stress on the device. When maintenance of the low-power wake-up PKE antenna circuit device 3 is required, the bolt 415 can be removed, and with the anti-stick layer 421, the cured silicone gel can be prevented from adhering to the inner wall of the housing 2. At this time, it can be easily cut or peeled with tools. Due to the limitations of the silicone gel properties, it does not stick to the surface and peels off smoothly, without risk of damage to the wires and precision chips in the low-power wake-up PKE antenna circuit device 3. This structure can provide overall protection for the low-power wake-up PKE antenna circuit device 3, preventing it from malfunctioning due to vibration damage.

[0029] Furthermore, the outer wall of bolt 415 is threaded into the inner thread of bolt hole 416, and the outer wall of bolt 415 is threaded into the inner thread of through hole 414. Under the constraint of bolt 415, the box body 2 can be installed on the top surface of mounting plate 1 through fixing plate 413.

[0030] Furthermore, the end of the filling tube 411 is connected to the top surface of the box 2, and the outer wall of the sealing bolt 412 is threaded into the inside of the filling tube 411. The box 2 is sealed to the top surface of the mounting plate 1 by bolts 415. When the sealing bolt 412 is opened, silicone gel is poured into the filling tube 411. The cured silicone gel can protect the low-power wake-up PKE antenna circuit device 3, preventing the low-power wake-up PKE antenna circuit device 3 from being damaged by vibration. Under the limitation of the characteristics of silicone gel, it will not affect the signal transmission of the low-power wake-up PKE antenna circuit device 3.

[0031] Example 2: Based on Example 1, a preferred embodiment of the low-power wake-up PKE antenna circuit structure provided by this utility model is as follows: Figures 1 to 6 As shown: The auxiliary component 42 includes an anti-stick layer 421 fixedly installed on the inner wall of the box body 2, a filter layer 422 provided on the outer side of the anti-stick layer 421, a moisture-proof layer 423 fixedly installed on the outer wall of the filter layer 422, a reinforcing layer 424 fixedly installed on the outer wall of the moisture-proof layer 423, a buffer layer 425 fixedly installed on the outer wall of the reinforcing layer 424, and a durable layer 426 fixedly installed on the outer wall of the buffer layer 425.

[0032] In this embodiment, under the protection and restriction of the low-power wake-up PKE antenna circuit device 3 by the housing 2, in order to avoid damage to the housing 2 by foreign objects, the overall wear and corrosion resistance of the housing 2 can be improved under the restriction of the toughness layer 426; under the restriction of the buffer layer 425, external forces can be buffered, preventing the housing 2 from directly transmitting external forces to the low-power wake-up PKE antenna circuit device 3; under the restriction of the enhancement layer 424, the signal transmission of the low-power wake-up PKE antenna circuit device 3 can be enhanced; under the restriction of the moisture-proof layer 423, external moisture can be prevented from damaging the low-power wake-up PKE antenna circuit device 3; under the restriction of the filter layer 422, external cluttered signals can be shielded, making the low-power wake-up PKE antenna circuit device 3 respond to signals more quickly; and under the restriction of the anti-stick layer 421, the cured silicone gel can be prevented from adhering to the inner wall of the housing 2.

[0033] Furthermore, the anti-stick layer 421 has an anti-stick coating on the side away from the box body 2, and the end of the anti-stick layer 421 away from the filling tube 411 is a sealing material. Under the restriction of the anti-stick layer 421, silicone gel can be prevented from adhering to the inner wall of the box body 2. Under the restriction of the anti-stick layer 421 with the sealing material at the end, uncured silicone gel can be prevented from overflowing from the connection between the box body 2 and the mounting plate 1.

[0034] In addition, the enhancement layer 424 is made of a signal enhancement material and the filter layer 422 is made of a shielding material. Under the restriction of the enhancement layer 424, the signal transmission effect of the low-power wake-up PKE antenna circuit device 3 can be enhanced. Under the restriction of the filter layer 422, the signal data of the non-low-power wake-up PKE antenna circuit device 3 can be shielded, so as to avoid external signal interference to the use of the low-power wake-up PKE antenna circuit device 3 and improve the response speed of the low-power wake-up PKE antenna circuit device 3.

Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
