B-surface type safety belt reminding sensor device based on micro switch

Disclosure of Invention

The invention relates to an automobile sensor, in particular to a B-surface type safety belt reminding sensor device based on a microswitch.

Background

The automobile safety belt is a device for ensuring that passengers and drivers are injured, and in an automobile safety accident, in order to reduce the injury of the safety accident to people, the automobile safety belt is almost provided with the safety belt on an automobile seat. In the process of automobile collision, the automobile safety belt is used as a basic protection device, and is very important for protecting drivers and passengers. When the seat has a passenger, the safety belt detection device can detect whether the seat belt is fastened, and if the passenger does not wear the seat belt, the vehicle can give an alarm. The common safety belt reminding devices are divided into two types, namely, an A-surface SBR and a B-surface SBR according to different positions.

Document 1 discloses an automobile safety belt reminding device, which includes a first pressure sensor, a second pressure sensor, an infrared transmitting and receiving module, a signal amplifying module, a filtering module, a processor, a delay module, an alarm module and a button module; signals detected by the first pressure sensor and the second pressure sensor are amplified and filtered by the signal amplification module and the filtering module and then input to the processor; the first pressure sensor is arranged below the automobile seat, and the second pressure sensor is arranged on the backrest of the automobile seat; the infrared transmitting and receiving module is connected with the processor and arranged on the backrest of the seat; the processor is connected with the alarm module through the delay module; the button module comprises an automobile safety belt reminding device starting/stopping button and a stopping alarm button.

The A-surface SBR is arranged between a seat surface and foaming, the foaming needs to be preset with an installation position, the foaming is fixed on the foaming through double-sided adhesive tape, a thin film resistor technology is used, and a required identification area is obtained through a plurality of pressure point tests. When the occupant is light in weight or the pressure distribution is dispersed, there is a risk of failure. Simultaneously, along with the promotion that the car travelling comfort required, front seat can increase the cushion heating function, and the sensor is reminded with A face type safety belt to the heating pad mutual interference, also can bring the safety belt and remind the functional failure risk.

Disclosure of Invention

The invention discloses a B-surface type safety belt reminding sensor based on a microswitch, aiming at the problems in the prior art, wherein the B-surface type safety belt reminding sensor deforms to generate horizontal motion after bearing load along with foaming, so that the microswitch is driven to generate action, the service life is long, and the environment-friendly effect of a full-belt reminding sensor device is achieved.

The technical scheme for realizing the invention is as follows: a B-surface type safety belt reminding sensor device based on a microswitch is characterized by comprising: terminal 3, sleeve pipe 4, electric wire 5, insulating cement 6, micro-gap switch 7, main part support 8, shell fragment 9 main part support 8 lower extreme set up micro-gap switch 7 main part support 8 in set up shell fragment 9, shell fragment 9 is in the state of bounceing, shell fragment 9 is connected with micro-gap switch 7's start button, terminal 3 passes through electric wire 5 electricity with micro-gap switch 7 and is connected micro-gap switch 7 sets up insulating cement 6 with the 5 junction of electric wire, sleeve pipe 4 parcel electric wire 5.

Further, it also includes: the terminal comprises a sheath 2 and a positioning clamp 1, wherein the sheath 2 is arranged outside the terminal 3, and the positioning clamp 1 is arranged on the side surface of the sheath 2.

The B-surface type safety belt reminding sensor device based on the microswitch has the beneficial effects that:

1. a microswitch-based B-surface type safety belt reminding sensor device is fixed on a spring frame steel wire, spring frame plastic or a foaming built-in steel wire of a seat, provides a stable elastic sheet deformation reference surface, transmits a signal to a controller of an automobile seat, effectively reduces the failure risk of the device, and ensures the stability and reliability of the electrical performance in the long-term use process;

2. the utility model provides a B face type safety belt reminds sensor device based on micro-gap switch, based on extrude micro-gap switch through the shell fragment for the execution core, along with the foaming bears the deformation that takes place behind the load and produces horizontal motion, and then drive micro-gap switch produces the action, and micro-gap switch will produce pressure signal and conduct whole car the control unit, if the passenger does not detain the safety belt, will send out the safety belt of police dispatch newspaper and remind sensor device.
