Description

Technical Field

[0001] This utility model relates to the technical field of automotive seat belts, specifically to an anti-mold automotive seat belt belt locking mechanism. Background Technology

[0002] Car seat belts are safety devices designed to restrain occupants during a collision and to prevent them from colliding with the steering wheel, dashboard, or other objects during a collision, or to prevent them from being ejected from the vehicle and suffering injury or death.

[0003] For example, a car seat belt locking mechanism with authorization announcement number "CN213473063U" solves the problem that existing car seat belt locking mechanisms cannot provide warnings before an accident occurs. The aforementioned mechanism uses a pressure sensor to detect pressure and prevent the seat belt from becoming too tight, allowing the person to sit back-to-back while driving or riding. In the event of sudden braking, it can limit the person's forward lean and prevent collisions, thus maximizing personal safety while ensuring comfort. However, considering that the buckles of existing car seat belt locking mechanisms often require the operator to forcefully insert them to achieve a lock, this method may be inconvenient for some people, especially the elderly or those with weak hand strength. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing car seat belt locking mechanisms are inconvenient for the elderly or people with weak hand strength, and to propose a mold-proof car seat belt locking mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mildew-proof car seat belt locking mechanism, comprising a fiber seat belt and a mounting shell, wherein the inner side of the mounting shell is fixedly connected to a ring claw, the inner wall of the ring claw is sleeved with a ratchet, the outer wall of the ratchet is inserted into a sleeve, and a protective mechanism is connected to the end of the sleeve.

[0006] This fiber seat belt is made of special material with excellent anti-mildew properties, effectively preventing mold growth in humid environments and extending the lifespan of the seat belt. The ratchet ensures quick locking in emergencies, thereby improving the seat belt's response speed. The insertion method of the sleeve and ratchet not only enhances the stability of the structure but also facilitates disassembly and maintenance.

[0007] Preferably, the protective mechanism includes a first gear, the side end of which is fixedly connected to a sleeve, the outer wall of the first gear meshing with a second gear, the outer wall of the second gear being fixedly connected to the output shaft of a servo motor, the outer wall of the servo motor being threadedly connected to the protective cover by bolts, and the outer wall of the protective cover being fixedly connected to a square block.

[0008] This setting allows the servo motor to precisely control the meshing of the first and second gears, enabling the sleeve on the first gear to control the tension of the fiber safety belt.

[0009] Preferably, the outer wall of the square block is inserted into the mounting shell, and the end of the fiber safety belt is connected to a locking mechanism.

[0010] This design incorporates a square block that plugs into the mounting housing, with bolts screwed into the outer wall of the square block to restrict its position. This facilitates future maintenance and replacement, ensures stable operation under various working conditions, and provides more comprehensive safety protection for occupants.

[0011] Preferably, the locking mechanism includes an insert plate, the rear end of which is movably connected to the fiber safety belt, an electric telescopic rod is installed on the inner wall of the insert plate, the output end of the electric telescopic rod is rotatably connected to the locking block, the outer side of the locking block is slidably connected to the insert plate, and the outer wall of the locking block is engaged with the groove of the insert sleeve.

[0012] This design incorporates a movable connection between the insert plate and the fiber safety belt to adapt to different usage scenarios. The electric telescopic rod further enhances the locking efficiency and reliability. Through the rotational connection between its output end and the locking block, the distance and position of the locking block can be quickly changed to complete the locking operation when needed. The sliding connection between the locking block and the insert plate not only enhances the flexibility of the overall structure but also ensures higher precision during the locking process. In addition, the locking block and the groove machined in the insert effectively prevent loosening caused by external impact, thereby significantly improving safety performance.

[0013] Preferably, the outer side of the socket is machined with an opening.

[0014] This feature allows for manual intervention in case of emergencies where the electric telescopic rod cannot control the movement of the locking block. Users can push the locking block through the opening to ensure safety.

[0015] Preferably, the insert plate surface is equipped with control buttons.

[0016] The control buttons are positioned in a reasonable manner, making it easy for operators to quickly locate and operate them. The control buttons are connected to the electric telescopic rod via a circuit, which can precisely control the movement of the locking block, thereby enabling the rapid locking or unlocking of the insert plate and sleeve on the fiber safety belt.

[0017] Preferably, a pressure sensor is installed on the outer wall of the fiber safety belt, and the output end of the pressure sensor is electrically connected to the servo motor.

[0018] This feature includes a pressure sensor that monitors changes in pressure on the fiber seatbelt in real time and transmits the data to the servo motor, thereby enabling intelligent adjustment of the seatbelt's tightness.

[0019] The present invention proposes a mildew-proof car seat belt locking mechanism with the following advantages: after the insert plate and the sleeve are connected without external obstruction, pressing the control button on the insert plate causes the electric telescopic rod to rotate the locking block through the output end, causing the locking block to continuously protrude outward and engage with the groove of the sleeve, thus completing the locking operation. In case of emergency, if the electric telescopic rod fails to work, the locking block can be manually pushed through the opening on the outside of the sleeve, ensuring safety and making it more convenient to use.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] Please see Figure 1-8 In this embodiment, a mildew-proof car seat belt locking mechanism includes a fiber seat belt 1 and a mounting shell 2. The inner side of the mounting shell 2 is fixedly connected to a ring claw 3. The inner wall of the ring claw 3 is sleeved with a ratchet 4. The outer wall of the ratchet 4 is inserted into a sleeve 5. A protective mechanism 6 is connected to the end of the sleeve 5.

[0031] The protective mechanism 6 includes a first gear 601, which is installed on the side of the mounting housing 2 via a protective cover 604. The protective cover 604 can protect the first gear 601, the second gear 60, and the servo motor 603. The side of the first gear 601 is fixedly connected to the sleeve 5. The outer wall of the first gear 601 meshes with the second gear 602. The outer wall of the second gear 602 is fixedly connected to the output shaft of the servo motor 603. The outer wall of the servo motor 603 is threadedly connected to the protective cover 604 via bolts. The outer wall of the protective cover 604 is fixedly connected to the square block 605.

[0032] The outer wall of the square block 605 is inserted into the mounting shell 2. The end of the fiber safety belt 1 is connected to a locking mechanism 7. The locking mechanism 7 includes an insert plate 701. The rear end of the insert plate 701 is movably connected to the fiber safety belt 1. An electric telescopic rod 702 is installed on the inner wall of the insert plate 701. The output end of the electric telescopic rod 702 is rotatably connected to the locking block 703. The outer side of the locking block 703 is slidably connected to the insert plate 701. The outer wall of the locking block 703 is engaged with the groove of the insert sleeve 704.

[0033] After the insertion plate 701 and the sleeve 703 are connected without any external obstruction, press the control button 9 on the insertion plate 701. The electric telescopic rod 702 rotates the locking block 703 through the output end, causing the locking block 703 to continuously protrude outward and engage with the groove of the sleeve 704, thus completing the locking operation. In case of an emergency, if the electric telescopic rod 702 cannot work, the locking block 703 can be manually pushed through the opening 8 on the outside of the sleeve 703 to ensure safety and make it more convenient to use.

[0034] An opening 8 is machined on the outer side of the insert 704, a control button 9 is installed on the surface of the insert plate 701, a pressure sensor 10 is installed on the outer wall of the fiber safety belt 1, and the output end of the pressure sensor 10 is electrically connected to the servo motor 603.

[0035] Working principle:

[0036] During installation, the mounting shell 2 is first installed in the designated position on the vehicle seat. The mounting shell 2 is fixed to the seat with bolts to ensure a firm installation that can withstand various vibrations and impacts during vehicle operation. Next, the single fiber seat belt 1 is passed through the insert plate 701, and the end of the fiber seat belt 1 is passed through the mounting shell 2. After the side end of the sleeve 5 is inserted into the fiber seat belt 1, one side of the sleeve 5 is inserted into the ratchet 4. The ratchet 4 and the sleeve 5 are tightly connected to ensure precise engagement, laying the foundation for the seat belt's belt-feel locking function.

[0037] Simultaneously, install the protective mechanism 6, fix the first gear 601 to the end of the sleeve 5, adjust the meshing state of the second gear 602 and the output shaft of the servo motor 603 to ensure smooth power transmission, connect the protective cover 604 to the servo motor 603 with bolts, then fix the square block 605 to the protective cover 604 and insert it into the mounting shell 2, and tighten the bolts to limit the position for easy subsequent maintenance and replacement.

[0038] A locking mechanism 7 is installed at the end of the fiber safety belt 1 to ensure that the insert plate 701 is flexibly connected to the safety belt. The electric telescopic rod 702 is fixed to the inner wall of the insert plate 701, and its output end is rotatably connected to the locking block 703. The locking block 703 slides smoothly with the insert plate 701 and can be accurately locked into the groove of the insert sleeve 704. An opening 8 is machined on the outside of the insert sleeve 704 so that manual intervention can be carried out in an emergency.

[0039] Control buttons 9 are installed on the surface of the insert plate 701 to ensure that the control buttons 9 and the electric telescopic rod 702 are connected normally and can accurately control the movement of the locking block 703. Pressure sensor 10 is installed on the outer wall of the fiber safety belt 1 and its output end is electrically connected to the servo motor 603.

[0040] During use, the occupant fastens the fiber seat belt 1. The pressure sensor 10 monitors the pressure changes on the seat belt in real time and transmits the data to the servo motor 603 through the controller. The servo motor 603 precisely controls the meshing of the first gear 601 and the second gear 602 to achieve intelligent adjustment of the tightness of the fiber seat belt 1 by the sleeve 5. When locking is required, the control button 9 on the insert plate 701 is pressed. The electric telescopic rod 702 rotates the locking block 703 through the output end, causing the locking block 703 to continuously protrude outward and engage with the groove of the insert sleeve 704 to complete the locking operation. If an emergency occurs and the electric telescopic rod 702 cannot work, the locking block 703 can be manually pushed through the opening 8 on the outside of the insert sleeve 703 to ensure safe use.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
