Description

Technical Field

[0001] This utility model mainly relates to the field of seat belt technology, specifically to a sound and light coordinated positioning safety component for seat belts. Background Technology

[0002] Among the passive safety features of automobiles, seat belts are a basic safety accessory that can secure occupants who are wearing seat belts correctly to their seats, thereby reducing injuries to passengers in the event of a traffic accident.

[0003] When seat belts function as a passive safety measure, they require the occupants of the vehicle to wear them correctly. If occupants use seat belt clips or only wear the seat belt on their chest while ignoring their waist, the seat belt may not be able to properly restrain the occupants in the event of a traffic accident.

[0004] To prevent passengers from being unprotected by seat belts in the event of an accident due to improper use, the inventors propose a sound-optical co-location safety component for seat belts. Building upon existing seat belt products that already include seat belt buckle switches and seat occupancy sensors, this component adds an NFC reader to the seam between the seat cushion and backrest. An NFC tag is affixed to the seat belt. When the occupant is using the seat belt normally, the seat occupancy sensor and seat belt buckle switch send information to the vehicle control system indicating that someone is in the seat and the seat belt latch is inserted into the buckle. The vehicle control system then sends a request to the NFC reader. If the NFC reader reads the NFC tag, the occupant is not fastening the seat belt to their waist; if it does not read the NFC tag, the vehicle control system determines that the occupant is wearing the seat belt correctly. Utility Model Content

[0005] 1. Technical problem solved by the utility model: This invention provides a sound and light coordinated positioning safety component for seat belts, which solves the technical problem that the wearing safety protection of existing seat belts is easily bypassed by seat belt clips.

[0016] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element; the terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] See attached document Figure 1-5 This utility model provides a sound and light coordinated positioning safety component for seat belts, comprising the following structure: The buttocks foam pad 1 has an NFC card reader 2 that is detachably connected to the top rear side of the buttocks foam pad 1. The NFC card reader 2 is electrically connected to the car ECU.

[0020] The seat belt 3 has an NFC tag 31 attached to the outside of the waist area. The far end of the seat belt 3 is fixed with a fixing card 4. The outside of the fixing card 4 is detachably connected to an audible and visual alarm 41, which is electrically connected to the vehicle ECU.

[0021] In this embodiment, a seat occupancy sensor is detachably connected to the bottom of the buttocks foam pad 1. The seat occupancy sensor is electrically connected to the vehicle ECU. A back foam pad 11 is detachably connected to the rear side of the buttocks foam pad 1. An movable gap is provided between the front of the back foam pad 11 and the rear side of the NFC card reader 2. The buttocks foam pad 1 is covered with a seat trim surface, and the back foam pad 11 is covered with a backrest trim surface.

[0022] The hip sponge pad 1 and back sponge pad 11 serve as the internal filling layers of the car seat. They typically require the inclusion of metal frame components. In this technical solution, the NFC reader 2 and seat occupancy sensor both require the fabrication of corresponding brackets based on the target vehicle's seat structure to complete their final assembly. The seat trim and back trim are standard designs in existing products. Considering that the NFC communication distance should be controlled within 4 cm, the thickness of the seat trim needs to be controlled within a maximum of 7 mm to reduce obstruction and interference.

[0023] In this embodiment, one end of the seat belt 3 is fixedly connected to the reel of the retractor 5, the top of the seat belt 3 is fitted with an upper limit clip 6, the outside of the seat belt 3 is movably fitted with a tongue 7, the bottom of the tongue 7 is detachably connected with a buckle 8, the inside of the buckle 8 is provided with a seat belt 3 buckle switch, and the seat belt 3 buckle switch is electrically connected to the vehicle ECU.

[0024] The retractor 5, upper limit stop 6, tongue 7, buckle 8, and fixing clip 4 are conventional components of the seat belt 3 installed in the vehicle. The buckle 8 is equipped with a seat belt 3 buckle switch to check whether the tongue 7 is inserted into the buckle 8 with the car ECU. This technical solution is the conventional application of the current seat belt 3 product.

[0025] In this embodiment, the NFC tag 31 is provided with an anti-abrasion rubber layer on its exterior. The number of anti-abrasion rubber layers corresponds to the number of NFC tags 31. The anti-abrasion rubber layers are discontinuously distributed on the exterior of the seat belt 3. The thickness of the anti-abrasion rubber layer superimposed on the seat belt 3 exceeds the width of the perforation of the seat belt 3 on the tongue 7. The middle part of the seat belt 3 and the end close to the fixing card 4 are respectively divided into a chest area and a waist area. The waist area is used for discontinuous pasting of multiple NFC tags 31.

[0026] The NFC tag 31 has an external anti-abrasion rubber layer to prevent it from being scratched and falling off. The anti-abrasion rubber layer, together with the seat belt 3, can replace the positioning card function of the seat belt 3 in limiting the tongue 7. The anti-abrasion rubber layer and the seat belt 3 work together to effectively prevent the tongue 7 from slipping onto the fixing card 4.

[0027] When the seat belt 3 product is in use, rescuers will cut the seat belt 3 to transfer the occupants to the outside of the vehicle for rescue. To avoid interference from the NFC tag 31 and the anti-wear rubber layer on the cutting operation, a discontinuous layout is chosen.

[0028] Detailed operating procedures: When an occupant sits on the hip cushion 1 inside the vehicle, the seat occupancy sensor sends a signal to the vehicle ECU indicating that the seat is occupied. At this time, the seat belt buckle switch 3 is not engaged, and the vehicle ECU will issue a reminder to the driver on the terminal display device that the seat belt 3 is not fastened. If the seat belt buckle 3 is engaged, but the NFC card reader 2 can read the NFC tag 31 information, then the lumbar area of ​​the seat belt 3 is not securing the occupant's waist. At this time, the vehicle ECU will issue a warning to the occupants through the audible and visual alarm 41. When there are many occupants in the vehicle, the combination of the audible and visual alarm 41 and the fixed card 4 makes it easy for the driver to quickly observe and locate the occupant who is not fastening the seat belt 3, and promptly remind the corresponding occupant to pay attention to and adjust the seat belt 3.

[0029] By adopting the technical solution of NFC reader 2 and NFC tag 31, the use of seat belt clip 3 can effectively avoid deceiving the car ECU. When the user uses seat belt clip 3, the seat belt 3 is basically in contact with the outer area of ​​the buttock foam pad 1 and back foam pad 11. At this time, the NFC tag 31 in the waist area of ​​seat belt 3 is within the detection range of NFC reader 2. Therefore, the car ECU can promptly detect that the seat belt 3 in the corresponding seat in the vehicle is not properly fastened. When the seat belt 3 is properly fastened, the tag 31 in the waist area is blocked by the human body and cannot be read by NFC reader 2.

[0030] In this technical solution, the front-end approach proposes a magnetic switch to replace the NFC reader 2 and a magnet to replace the NFC tag 31. Considering the possible presence of metal magnets on occupants' clothing and the ease of obtaining magnets, the NFC reader 2 and NFC tag 31 are adopted to prevent users from easily obtaining related products to deceive the car ECU and evade the use of seat belts 3. At the same time, an audible and visual alarm 41 is configured to allow the driver to quickly observe and locate people in the vehicle who are not using seat belts 3 correctly, ensuring that all occupants in the vehicle can use seat belts 3 correctly and reducing the probability of injury to occupants in the event of an accident.

[0031] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
