Description

Technical Field

[0001] This utility model relates to the field of automotive sensor technology, and in particular to a seat B-side sensor. Background Technology

[0002] With economic development, the number of vehicles owned by families is increasing, and vehicle safety is receiving more and more attention from designers and users. When riding in a car, passengers are required to use seat belts. Existing seat sensors are primarily for passenger safety. Car seats are generally equipped with pressure sensors to detect the presence of passengers. When a passenger is seated, the pressure sensor detects the pressure and outputs an on / off signal to the alarm, thus reminding the passenger to fasten their seat belt. However, existing pressure sensors are directly installed on the seat surface, making them unstable at high temperatures, and their recycling is inconvenient and environmentally unfriendly.

[0003] Therefore, it is necessary to invent a seat B-side sensor to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a seat B-side sensor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a seat B-side sensor, including a support assembly, wherein an elastomer assembly is provided on the top of the support assembly;

[0006] The support assembly includes a base, and the top of the base is provided with a mounting groove. The mounting groove is symmetrically provided with clamping plates inside, and the bottom end of the clamping plates is integrally formed with the bottom inner wall of the mounting groove. A micro switch is snapped between the two clamping plates.

[0007] The elastomer assembly includes an elastomer body, and a circular groove is formed through the center of the top of the elastomer body.

[0008] Preferably, the two clamping plates have clamping grooves on their sides that are close to each other, and the micro switch is engaged inside the clamping grooves.

[0009] Preferably, slots are provided through both sides of the base, and extension blocks are integrally formed at the bottom ends of both sides of the base, with straight grooves communicating with the slots at the top of the extension blocks.

[0010] Preferably, the base has protrusions integrally formed at the bottom center of both the front and back sides, and a groove is formed at the top center of the protrusions.

[0011] Preferably, the outer side wall of the base is integrally formed with multiple ear plates, and the multiple ear plates are distributed in a ring array.

[0012] Preferably, the top of the outer side wall of the elastomer body is arc-shaped, and the bottom end of the circular groove is snapped onto the top of the micro switch.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention replaces existing pressure sensors by employing a support assembly, a micro switch, and an elastomer assembly. The support assembly serves as a base that can be installed on the seat's B-side for easy disassembly and maintenance. The elastomer assembly has excellent elasticity, allowing it to deform under pressure and actuate the input of the micro switch, thus activating the micro switch, completing the circuit, and detecting the presence of a passenger in the seat. This achieves the function of existing pressure sensors. The entire sensor remains stable even at high temperatures, and the micro switch can be directly removed from the support assembly, and the elastomer assembly can be directly detached from the micro switch. All components—the support assembly, micro switch, and elastomer assembly—are recyclable and environmentally friendly. Attached Figure Description

[0019] 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.

[0020] This utility model provides, for example Figure 1-3 The seat B-side sensor shown includes a support assembly 1, and an elastomer assembly 3 is provided on the top of the support assembly 1;

[0021] The support assembly 1 includes a base 101, and a mounting groove 102 is formed at the top of the base 101. Clamping plates 103 are symmetrically arranged inside the mounting groove 102, and the bottom end of the clamping plates 103 is integrally formed with the inner wall of the bottom end of the mounting groove 102. A micro switch 2 is snapped between the two clamping plates 103. By using the support assembly 1, micro switch 2, and elastomer assembly 3, the existing pressure sensor is replaced. The support assembly 1, as the base, can be installed on the seat B-side for easy disassembly and maintenance. The elastomer assembly 3 has excellent elasticity and can deform when compressed, causing the input end of the micro switch 2 to move slightly, thereby opening the micro switch 2, making the circuit conductive, and thus sensing the presence of a passenger on the seat, thereby realizing the function of the existing pressure sensor. The entire sensor does not affect stability at high temperatures, and the micro switch 2 can be directly removed from the support assembly 1. The elastomer assembly 3 can be directly removed from the microswitch 2. The support assembly 1, microswitch 2 and elastomer assembly 3 can all be directly recycled and reused, which is environmentally friendly. The two clamping plates 103 have clamping grooves 104 on their close sides, and the microswitch 2 is snapped into the inside of the clamping groove 104. The base 101 has slots 105 through on both sides. The bottom ends of both sides of the base 101 are integrally formed with extension blocks 107, and the top of the extension blocks 107 has a straight groove 108 communicating with the slots 105. The front and back bottom ends of the base 101 are integrally formed with protrusions 109, and the top center of the protrusions 109 has a recessed groove 110. The extension blocks 107 and protrusions 109 can increase the stability of the base 101. The top of the outer wall of the base 101 is integrally formed with multiple ear plates 106, and the multiple ear plates 106 are distributed in a ring array.

[0022] The elastomer assembly 3 includes an elastomer body 301, which has good elasticity and can be made of non-metallic elastomers. All non-metallic elastomers with elasticity are acceptable. A circular groove 302 is provided through the middle of the top of the elastomer body 301. The top of the outer wall of the elastomer body 301 is arc-shaped. The bottom of the circular groove 302 is snapped onto the top of the micro switch 2.

[0023] Working principle of this utility model:

[0024] In use, the support assembly 1 is fixedly installed on the B side of the seat. Then, the micro switch 2 is inserted into the two clamping slots 104 and snapped in place. The elastic body assembly 3 is then snapped onto the input end of the micro switch 2. In use, the elastic body assembly 3 deforms when compressed, causing the input end of the micro switch 2 to move slightly, thereby opening the micro switch 2, making the circuit conductive, and thus sensing that there is a passenger on the seat, thereby realizing the function of the existing pressure sensor.
