Description

Technical Field

[0001] This utility model relates to the field of automotive side door handle technology, specifically an antenna-type switch for automotive side door handles. Background Technology

[0002] With the rapid development of intelligent and connected vehicles, users have put forward higher requirements for the convenience, safety and technological feel of car operation. Traditional mechanical keys or physical button-type door opening methods are gradually being replaced by more intelligent keyless entry systems. As a key part of the interaction between users and vehicles, the design of the switch structure of the car side door handle directly affects the user experience and vehicle safety. Therefore, antenna-type side handle switches are used to replace traditional mechanical keys.

[0003] Chinese Utility Model Patent Publication No. CN203721872U discloses an antenna-type switch for a car side door handle. The specification of this car side door handle antenna-type switch includes an antenna and a housing. The antenna is an antenna device provided by this utility model. The door microswitch of the antenna device corresponds to the microswitch button on the housing. This car door handle utilizes the aforementioned antenna device, facilitating quick assembly of the antenna device. Furthermore, the car door handle provided by this utility model avoids the need for separate door microswitches and antenna magnetic coils, resulting in fewer assembly parts and simpler assembly. However, this car side door handle antenna-type switch lacks a protective structure for the connecting wire harness. While it allows for quick assembly, it is inconvenient to tighten multiple sets of wires, easily leading to a larger footprint. Moreover, the lack of an independent channel for the connecting wires makes it prone to tangling or compression when passing through the antenna, thus affecting its normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an antenna-type switch for car side door handles. It can effectively solve the problems in the prior art, which, although it can achieve quick assembly, is not convenient for tightening multiple sets of wires, easily leads to a large area occupied, and does not have an independent channel for connecting wires, which can easily cause the connecting wires to get tangled or squeezed when passing through the antenna, thus affecting its normal use.

[0005] The technical solution adopted by this utility model is: an antenna-type switch for a car side door handle, including a communication connector, a connecting line, a micro switch and a sensing component arranged sequentially from left to right. The communication connector, the micro switch and the sensing component are all connected by the connecting line. A connecting sleeve is fixedly installed at one end of the communication connector near the micro switch, and the connecting line is located on the inner wall of the connecting sleeve.

[0006] The sensing component includes a sensing antenna and a limiting frame. The sensing antenna and the limiting frame are plugged in and have an interference fit. The limiting frame has a through slot extending from one end of the communication connector to one end of the micro switch, and the connecting wire passes through the through slot.

[0007] Preferably, the inductive antenna has a slot one and a slot two at one end near the limiting frame. The cross-section formed by the slot one and slot two is an "L" shape. Insert plates are fixedly installed at the edges of both ends of the limiting frame, and the insert plates are plugged into the slot one and slot two.

[0008] Through the above technical solution, by cooperating with slot one and slot two and insert plate, the insert plate can be inserted into slot one and slot two during installation, which can realize the quick installation of induction antenna and limit bracket. Moreover, the interference fit between the two can prevent them from easily falling off due to vibration when the car is in motion, thus affecting their normal use.

[0009] Preferably, the lengths of the insert plate, slot one, and slot two are shorter than the length of the limiting frame, and the sensing antenna is provided with connection ports at both ends near the communication connector and the micro switch, and the sensing antenna is connected to the connecting line through the connection ports.

[0010] The above technical solution provides buffer space for the induction antenna by using a plug and slot that are shorter than the limiting frame, thus avoiding antenna deformation caused by excessive tightness during assembly. Furthermore, the connection ports at both ends enable bidirectional connection between the induction antenna and the connecting wire, allowing for signal transmission.

[0011] Preferably, the cross-section of the through groove is circular, and multiple identical through grooves are provided, with the multiple through grooves distributed at equal intervals.

[0012] The above technical solution provides an independent wire-passing channel for the connecting wires through multiple equally spaced circular slots, avoiding wire tangling or compression. In addition, the equally spaced design makes it easier for two wires to communicate due to electromagnetic interference.

[0013] Preferably, a protective sleeve is fixedly installed at the end of the connecting sleeve away from the communication connector, and the protective sleeve is in contact with the connecting wire.

[0014] The above technical solution uses a protective sleeve at the end of the connecting sleeve to fit the connecting wire, which buffers the rigid contact between the wire and the connecting sleeve, avoids wire wear caused by long-term vibration, and improves the service life of the connecting wire.

[0015] Preferably, there are multiple identical connecting sleeves, protective sleeves, and connecting wires, and the multiple connecting sleeves, protective sleeves, and connecting wires correspond one-to-one. A wire harness integrated sleeve is provided at the outer edge of the multiple connecting wires.

[0016] The above technical solution achieves modular functionality by using multiple connecting sleeves, protective sleeves, and connecting wires in a one-to-one correspondence. The wire harness integration sleeve also bundles multiple sets of wires together, reducing space occupation and streamlining the wire harness routing to avoid interference with other components inside the door, thus improving assembly efficiency.

[0017] Preferably, a protective sleeve, which is a rubber sleeve, is fixedly installed at the connection point between the connecting wire and the micro switch.

[0018] The above technical solution involves wrapping the connection between the connecting wire and the micro switch with a protective sleeve made of rubber. The elastic deformation of the rubber fills the gaps, enhancing insulation and vibration resistance, and preventing the connecting wire from breaking due to bending.

[0019] Compared with the prior art, this utility model provides an antenna-type switch for automotive side door handles, which has the following advantages:

[0020] 1. This car side door handle antenna switch, with its compact antenna and micro switch, can be completely hidden inside the door handle. It communicates with the whole vehicle through a connector to unlock and open the door, eliminating the traditional pulling action and improving the overall practicality of the antenna switch. In addition, the quick installation of the induction antenna and the limit bracket, as well as the interference fit between the two, can prevent the two from easily falling off due to vibration when the car is in motion, thus affecting its normal use.

[0021] 2. This car side door handle antenna switch achieves modular functionality through multiple connecting sleeves, protective sleeves, and connecting wires that correspond one-to-one. The wire harness integration sleeve tightly binds multiple sets of wires, reducing space occupation and streamlining the wire harness routing to avoid interference with other components inside the door, thus improving assembly efficiency. Multiple equally spaced circular slots provide independent wire passages for the connecting wires, preventing wire harness tangling or compression. Furthermore, the equally spaced design prevents electromagnetic interference between two wire harnesses from affecting their communication signal transmission. Attached Figure Description

[0031] 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.

[0032] Example 1: As Figure 1-8 As shown, the present invention provides an antenna-type switch for a car side door handle, comprising a communication connector 1, a connecting line 4, a micro switch 6, and a sensing component 7 arranged sequentially from left to right. The communication connector 1, the micro switch 6, and the sensing component 7 are all connected by the connecting line 4. A connecting sleeve 2 is fixedly installed at one end of the communication connector 1 near the micro switch 6, and the connecting line 4 is located on the inner wall of the connecting sleeve 2.

[0033] The sensing component 7 includes a sensing antenna 701 and a limiting frame 705. The sensing antenna 701 and the limiting frame 705 are plugged in and have an interference fit. The limiting frame 705 has a through slot 707 extending from one end of the communication connector 1 to one end of the micro switch 6. The connecting wire 4 passes through the through slot 707.

[0034] Specifically, the induction antenna 701 has a slot 1 703 and a slot 2 704 at one end near the limiting frame 705. The cross-section formed by slot 1 703 and slot 2 704 is an "L" shaped structure. Insert plates 706 are fixedly installed at both ends of the limiting frame 705. The insert plates 706 are plugged into slot 1 703 and slot 2 704. The advantage is that, through the cooperation of slot 1 703 and slot 2 704 with insert plates 706, insert plates 706 can be inserted into slot 1 703 and slot 2 704 during installation, which can realize the quick installation of induction antenna 701 and limiting frame 705. Moreover, the interference fit between the two can prevent them from easily falling off due to vibration when the car is in motion, thus affecting their normal use.

[0035] Specifically, the lengths of the insert plate 706, slot 1 703, and slot 2 704 are shorter than the length of the limiting bracket 705. The inductive antenna 701 has connection ports 702 at both ends near the communication connector 1 and the micro switch 6. The inductive antenna 701 is connected to the connecting line 4 through the connection ports 702. The advantage is that the shorter lengths of the insert plate 706 and slots compared to the limiting bracket 705 provide buffer space for the inductive antenna 701, avoiding antenna deformation caused by excessive tightness during assembly. Furthermore, the connection ports 702 at both ends enable bidirectional connection between the inductive antenna 701 and the connecting line 4, allowing for signal transmission.

[0036] Specifically, the cross-section of the through slot 707 is circular. Multiple through slots 707 are provided and distributed at equal intervals. The advantage is that multiple equally distributed circular through slots 707 provide independent wire passages for the connecting wire 4, avoiding wire tangling or compression. In addition, the equal spacing design makes it easier for two wires to be affected by electromagnetic interference, thus affecting their communication signal transmission.

[0037] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, a protective sleeve 3 is fixedly installed at the end of the connecting sleeve 2 away from the communication connector 1. The protective sleeve 3 is in contact with the connecting wire 4. The advantage is that by the protective sleeve 3 at the end of the connecting sleeve 2 being in contact with the connecting wire 4, the rigid contact between the wire 4 and the connecting sleeve 2 can be buffered, which can avoid wire wear caused by long-term vibration and improve the service life of the connecting wire 4.

[0039] Specifically, multiple identical connecting sleeves 2, protective sleeves 3, and connecting wires 4 are provided, with each connecting sleeve 2, protective sleeve 3, and connecting wire 4 corresponding one-to-one. A wire harness integration sleeve 5 is provided at the outer edge of each connecting wire 4. The advantage is that by having multiple connecting sleeves 2, protective sleeves 3, and connecting wires 4 correspond one-to-one, functional modularization is achieved. Furthermore, the wire harness integration sleeve 5 tightly binds multiple sets of wires, reducing space occupation, while also organizing the wire harness routing to avoid interference with other components inside the door, thus improving assembly efficiency.

[0040] Specifically, a protective sleeve 8 is fixedly installed at the connection point between the connecting wire 4 and the micro switch 6. The protective sleeve 8 is a rubber sleeve. The advantage is that by wrapping the connection point between the connecting wire 4 and the micro switch 6 with the rubber protective sleeve 8, the elastic deformation of the rubber fills the gap, enhances insulation and vibration resistance, and can prevent the connecting wire 4 from breaking due to bending.

[0041] Working Principle: During use, the insertion plate 706 is inserted into slots 703 and 704 to facilitate quick installation of the induction antenna 701 and the limiting bracket 705. The interference fit between them prevents them from easily detaching due to vibrations while the vehicle is in motion, thus ensuring normal operation. The insertion plate 706 and slots are shorter than the limiting bracket 705, providing buffer space for the induction antenna 701 and preventing antenna deformation due to excessive tightness. The connection ports 702 at both ends allow for bidirectional connection between the induction antenna 701 and the connecting wire 4, enabling signal transmission. Multiple equidistant circular slots 707 provide independent passageways for the connecting wire 4, preventing wire tangling. The design, including compression and equal spacing, makes it easy for electromagnetic interference between the two wire harnesses to affect their communication signal transmission. The protective sleeve 3 at the end of the connecting sleeve 2 fits the connecting wire 4, which buffers the rigid contact between the wire 4 and the connecting sleeve 2, avoiding wire wear caused by long-term vibration and improving the service life of the connecting wire 4. By having multiple connecting sleeves 2, protective sleeves 3 and connecting wires 4 correspond one-to-one, functional modularization is achieved. The wire harness integration sleeve 5 bundles multiple sets of wires tightly, reducing space occupation, and at the same time, it organizes the wire harness route, avoiding interference with other parts inside the door and improving assembly efficiency. The rubber protective sleeve 8 wraps the connection between the connecting wire 4 and the micro switch 6, and the elastic deformation of the rubber fills the gap, enhancing insulation and vibration resistance, and preventing the connecting wire 4 from breaking due to bending.
