Abstract
The utility model discloses a fix a position reliable car blet, including meshbelt, coiler and spring bolt, the one end of meshbelt links to each other with the coiler, and the spring bolt slip cap is on the meshbelt, and the both ends of meshbelt are equipped with respectively along the axially extended magnetism sensor bar of meshbelt, are equipped with the hall element and the 2nd hall element that are used for induced magnetism sensor bar on coiler and the spring bolt respectively, and the first signal of telecommunication is exported during to magnetism sensor bar to a hall element and the 2nd hall element sensing, exports the second signal of telecommunication when sensing does not arrive magnetism sensor bar. The utility model discloses a two sets of signals can be exported in a hall element and the 2nd hall element and magnetism sensor bar cooperation work, can know the meshbelt position that the coiler coiled and the position of spring bolt based on these two sets of signals, utilize these two sets of positional information can more accurately judge the state of wearing of safety belt to play better safe warning effect.
Description
Technical field
The utility model relates to a kind of car belt field, is specifically related to a kind of location failure-free car belt.
Background technology
Current automobile has become the vehicle indispensable in life.And safety to be people go on a journey the most basic demand, automobile driving safe has also become the problem of chaufeur and occupant's overriding concern, is also one of most important performance of automobile.
Occupant in collision happens or when using emergency braking, can fasten on the seat, prevents secondary collision, avoid or alleviate the injured degree of driver and crew by car belt firmly.But often there will be the personal casualty phenomenon caused because of non-wear safety belt at present; wear safety belt is had in order to ensure after chaufeur or passenger loading; car belt system all can be configured with detection alarm device, carries out alarm when chaufeur or the non-wear safety belt of passenger being detected.A kind of detection alarm device common at present arranges magnetic induction bar at ribbon, at coiler, Hall element is set, by Hall element, detection response is carried out to magnetic induction bar, detect the stretched length size obtaining ribbon, thus the wear condition of safety strap is judged.Thisly carry out detecting the device of ribbon telescopic location owing to only having a signal by the Hall element in coiler, therefore its Detection results unreliable.
Utility model content
For above technical matters, the utility model provides a kind of location failure-free car belt, and can detect the wearing state of safety strap more exactly, safety factor is improved.
The technical scheme that the utility model adopts for its technical matters of solution is:
A kind of location failure-free car belt, comprise ribbon, coiler and dead bolt, one end of ribbon is connected with coiler, dead bolt slides and is placed on ribbon, the two ends of ribbon are respectively equipped with along the axially extended magnetic induction bar of ribbon, coiler and dead bolt are respectively equipped with the first Hall element and the second Hall element of responding to bar for induced magnetism, export the first electric signal when the first Hall element and the second Hall element sense magnetic induction bar, sense and export the second electric signal less than during magnetic induction bar.
As preferred embodiment, described magnetic induction bar is built in an adhesive tape, and adhesive tape is clinged on ribbon by viscose glue.
As preferred embodiment, the width of described adhesive tape is equal with the width of ribbon.
The beneficial effects of the utility model are: the first Hall element of the present utility model and the second Hall element and magnetic induction bar cooperating can export two groups of signals, the position of the ribbon position that coiler reels and dead bolt can be known based on these two groups of signals, utilize these two groups of location informations can judge the wearing state of safety strap more accurately, thus play better safety prompt function effect.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the generalized section of a kind of embodiment of ribbon.
Accompanying drawing illustrates: 1-ribbon, 2-coiler, 3-dead bolt, 4-magnetic induction bar, 5-adhesive tape.
Detailed description of the invention
See figures.1.and.2, the utility model disclosed a kind of location failure-free car belt mainly comprises ribbon 1, coiler 2 and dead bolt 3.One end of ribbon 1 is connected with coiler 2, and under the effect of coiler 2, ribbon 1 can be retracted or stretch out.Dead bolt 3 slides and is placed on ribbon 1, and position when dead bolt 3 inserts in the socket on seat on ribbon 1 exists very large difference with position when not inserting.
The utility model is respectively equipped with along the axially extended magnetic induction bar 4 of ribbon 1 at the two ends of ribbon 1, coiler 2 and dead bolt 3 are respectively equipped with the first Hall element and the second Hall element of responding to bar 4 for induced magnetism.During work, when the first Hall element and the second Hall element sense magnetic induction bar 4, export the first electric signal, sense and export the second electric signal less than during magnetic induction bar 4.According to the first Hall element and the second Hall element send signal can judge residing for ribbon 1 length that coiler 2 reels and dead bolt 3 for the first electric signal or the second electric signal position, thus judge the wearing state of safety strap exactly, can warning reminding be carried out when checking out passenger to wear safety strap.
In order to make arranging of magnetic induction bar 4 convenient, magnetic induction bar 4 can be built in an adhesive tape 5, and adhesive tape 5 is clinged on ribbon 1 by viscose glue.During application, the length of adhesive tape 5 and distributing position can be configured as required, use flexibly, and then only adhesive tape 5 need be torn when requiring replacement is stained with new adhesive tape 5.In addition, after being stained with ribbon 1 to make adhesive tape 5, structure is more complete, and the width of adhesive tape 5 is set to equal with the width of ribbon 1.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
1. a location failure-free car belt, comprise ribbon, coiler and dead bolt, one end of ribbon is connected with coiler, dead bolt slides and is placed on ribbon, it is characterized in that: the two ends of ribbon are respectively equipped with along the axially extended magnetic induction bar of ribbon, coiler and dead bolt are respectively equipped with the first Hall element and the second Hall element of responding to bar for induced magnetism, first Hall element and the second Hall element export the first electric signal when sensing magnetic induction bar, sense and export the second electric signal less than during magnetic induction bar.
2. one location according to claim 1 failure-free car belt, is characterized in that: described magnetic induction bar is built in an adhesive tape, and adhesive tape is clinged on ribbon by viscose glue.
