Description

Technical Field

[0001] This invention relates to the field of seat belt locking technology, and more specifically to an automatic locking structure and locking method for a seat belt with a protective structure. Background Technology

[0002] Existing conventional vehicle seat belts typically use a buckle and a retractor. A weighted pendulum within the retractor swings forward due to inertia, causing a pawl to engage a ratchet gear, instantly locking the retractor's rotation. This is similar to a seat belt automatic locking structure and method described in patent CN202310657984.X. This automatic locking structure includes at least: a seat belt buckle; a seat belt latch adapted to the buckle; and a position sensing module located on the latch, suitable for sensing the interaction between the buckle and the seat belt. The system includes information on the distance between the seatbelt buckle and the seatbelt latch; an audible prompt module electrically connected to the position sensor module, which emits a first prompt tone based on the distance information to guide the user in adjusting the position of the seatbelt latch; this automatic seatbelt locking structure uses the position sensor module to obtain information on the distance between the seatbelt buckle and the seatbelt latch, and the audible prompt module emits a first prompt tone based on this distance information to guide the user in adjusting the position of the seatbelt latch, thus facilitating seatbelt locking without requiring the user to deliberately search for it or twist their body, saving time and effort and improving the user experience.

[0003] However, while this type of conventional seatbelt is more suitable for use in the driver's seat, it cannot be used in racing cars or child seats. In actual use, the body may pop out from the top and bottom of the seatbelt. At the same time, it cannot be properly fitted and tensioned, causing the person restrained by the seatbelt to fall off. In addition, it is inconvenient to install, remove and replace the seatbelt. Summary of the Invention

Detailed Implementation

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] In the description of this application, it should be understood that the terms "middle," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] Example 1:

[0040] like Figure 1 and Figure 2 As shown, a seat belt automatic locking structure and locking method with protective structure includes an automatic locking device 2, which is locked and adjusted at the inner ends of multiple fixed fastening straps 1, and the outer ends of the multiple fixed fastening straps 1 are all locked and fixed to the vehicle seat.

[0041] The working principle and beneficial effects of this embodiment are as follows: By locking and adjusting multiple fixed straps 1 in the automatic locking device 2, the outer ends of the multiple fixed straps 1 are locked and fixed on the seat, thereby locking the fixed straps 1 at different angles and directions on the seat. By installing multiple fixed straps 1 in several specific positions and inserting them into the automatic locking device 2 for locking and integration, and by simultaneously adjusting and tightening the multiple fixed straps 1 on the automatic locking device 2, they are secured to the passenger, thus completing the adjustment of the seat belt usage.

[0042] This addresses the issue that while conventional seat belts are more suitable for use in the driver's seat, they are not compatible with racing cars or child seats, and in practice, the body may slip out from the top or bottom of the seat belt. It also solves the problem of the inability to adjust the fit and tension properly, which can cause the person restrained by the seat belt to fall off. Furthermore, it resolves the inconvenience of installing, removing, and replacing seat belts.

[0043] Example 2:

[0044] like Figure 1 — Figure 11 As shown, an automatic locking structure and locking method for a seat belt with a protective structure are disclosed. The fixed fastening strap 1 includes a webbing 3, an outer locking tongue 4, an inner locking tongue 5, and a guide plate 6. The outer locking tongue 4 and the inner locking tongue 5 are fixed at both ends of the webbing 3, respectively. The outer end of the webbing 3 is locked and fixed to the seat by the outer locking tongue 4, and the inner end of the webbing 3 is locked and adjusted on the automatic locking device 2 by the inner locking tongue 5. The guide plate 6 is wound around the webbing 3.

[0045] The working principle and beneficial effects of this embodiment are as follows: The two ends of the webbing 3 are respectively fixed with an outer locking tongue 4 and an inner locking tongue 5. The outer end of the webbing 3 is locked and fixed to the seat by the outer locking tongue 4, and the inner end of the webbing 3 is locked and adjusted to the automatic locking device 2 by the inner locking tongue 5, thereby wrapping the passenger in the webbing 3 to achieve the effect of wrapping and protecting safety. The guide plate 6 is wrapped around the webbing 3, and the seat belt guide plate can help the driver and passenger wear the seat belt correctly, thereby improving the usage rate and correct wearing rate of the seat belt.

[0046] Example 3:

[0047] like Figure 1 — Figure 11 As shown, an automatic locking structure and locking method for a safety belt with a protective structure are disclosed. The webbing 3 is provided with a honeycomb braided buffer strip 7, and the honeycomb braided buffer strip 7 is provided with multiple slots.

[0048] The working principle and beneficial effects of this embodiment are as follows: Traditional webbing 3 usually does not have elasticity and is prone to damage and breakage after repeated pulling. By setting a honeycomb braided buffer strip 7 inside the webbing 3, and placing the honeycomb braided buffer strip 7 between the webbing 3, the buffering capacity is increased by using three-dimensional weaving in specific areas of the honeycomb braided buffer strip 7 and setting multiple slots inside the honeycomb braided buffer strip 7. Thus, the webbing 3 has its own buffering elasticity during use, and its elasticity is not particularly large, which is convenient for buffering during actual use, while ensuring its restraining force, thereby reducing the possibility of damage and breakage after repeated pulling. This makes it have a protective effect for its durable use.

[0049] Example 4:

[0050] like Figure 1 — Figure 11 As shown, an automatic locking structure and locking method for a seat belt with a protective structure are disclosed, wherein locking holes are provided on both the outer locking tongue 4 and the inner locking tongue 5.

[0051] The working principle and beneficial effects of this embodiment are as follows: both the outer locking tongue 4 and the inner locking tongue 5 are provided with locking holes. The locking holes on the outer locking tongue 4 facilitate its installation and use on the vehicle seat, while the locking holes on the inner locking tongue 5 facilitate its insertion into the automatic locking device 2 for installation and use, making it easy to lock and use.

[0052] Example 5:

[0053] like Figure 1 — Figure 11As shown, an automatic locking structure and locking method for a safety belt with a protective structure are disclosed. The automatic locking device 2 includes a locking housing 8, a locking base 9, a tension adjuster 10, and a locking button 11. An outer insert ring is provided between the locking housing 8 and the locking base 9. The middle ends of the locking housing 8 and the locking base 9 are connected by the tension adjuster 10. The locking button 11 is longitudinally slidably arranged inside the tension adjuster 10.

[0054] The working principle and beneficial effects of this embodiment are as follows: Based on actual usage needs, different numbers of fixing straps 1 are placed in different positions for use. They are fixed inside the seat by the outer locking tongue 4, and the inner end of the inner locking tongue 5 is inserted into the outer insertion ring provided between the locking housing 8 and the locking base 9. By pressing down the locking button 11, the inner locking tongue 5 is inserted; releasing the locking button 11 fixes the inner locking tongue 5, completing the automatic locking installation of the fixing straps 1. The tension of the fixing straps 1 can be adjusted by adjusting the tension adjuster 10. For convenient overall use, one of the fixing straps 1 must always be connected inside the automatic locking device 2 to prevent it from falling off and being lost.

[0055] Example 6:

[0056] like Figure 1 — Figure 11 As shown, an automatic locking structure and locking method for a safety belt with a protective structure are disclosed. The locking housing 8 is provided with a reverse threaded groove ring 13. The reverse threaded groove ring 13 is connected to a reverse threaded seat 14 through a reverse thread engagement. The reverse threaded seat 14 is fixed to the lower end of the reverse locking threaded cone barrel 12. The inner wall of the reverse locking threaded cone barrel 12 is provided with an inner locking cone 15 that fits against the outer wall of the tension adjuster 10. The upper end of the outer wall of the tension adjuster 10 is provided with multiple rotating grooves.

[0057] The working principle and beneficial effects of this embodiment are as follows: When the tension adjustment device 10 is needed to adjust the tension of the fixed strap 1, the tension adjustment device 10 is rotated, which drives the locking button 11 to rotate, thereby causing the locked fixed strap 1 to move in a circular motion around the center of the locking housing 8 and the locking base 9, thus tightening it, so that the fixed strap 1 can be tightly secured to the passenger; by rotating the anti-locking threaded cone 12 in the opposite direction, the anti-threaded seat 14 at the lower end of the anti-locking threaded cone 12 can rotate downward in the anti-threaded groove ring 13, thereby causing the anti-locking threaded cone 12 to drive the inner locking cone 15 on the inner wall to fit against the outer wall of the tension adjustment device 10. The resistance is increased by the multiple slots on the inner wall of the inner locking cone 15, thereby locking and fixing the tension adjustment device 10 after adjustment, thus completing the locking after tightening.

[0058] Example 7:

[0059] like Figure 1— Figure 11 As shown, an automatic locking structure and locking method for a safety belt with a protective structure are disclosed. The lower end of the tension adjuster 10 is provided with a rotating base 16. The tension adjuster 10 is rotatably connected to the middle end of the locking base 9 through the rotating base 16. The inner wall of the tension adjuster 10 is provided with a plurality of limiting grooves 18. The upper end of the inner wall of the limiting groove 18 is provided with a baffle. The outer wall of the tension adjuster 10 is provided with a plurality of communicating limiting grooves 19.

[0060] The working principle and beneficial effects of this embodiment are as follows: The tension adjuster 10 is rotatably connected to the middle of the locking base 9 via the rotating base 16, thereby facilitating the rotation of the tension adjuster 10 between the locking housing 8 and the locking base 9. Multiple limiting grooves 18 are provided on the inner wall of the tension adjuster 10, and a baffle is provided at the upper end of the inner wall of the limiting groove 18, thereby facilitating the rotation of the locking button 11 while allowing the locking button 11 to slide longitudinally within the tension adjuster 10, facilitating its locking use. Multiple connecting limiting grooves 19 provided on the outer wall of the tension adjuster 10 facilitate the longitudinal sliding and rotation of the locking button 11, preventing interference.

[0061] Example 8:

[0062] like Figure 1 — Figure 11 As shown, an automatic locking structure and locking method for a safety belt with a protective structure are disclosed. The locking button 11 includes a locking button 20, a button operation slide 21, a connecting platform 22, and locking pins 23. The locking button 20 is fixed to the upper end of the button operation slide 21. The outer wall of the button operation slide 21 is slidably disposed in the limiting slide groove 18 by a limiting slider. Multiple connecting platforms 22 are fixed to the outer wall of the button operation slide 21. The multiple connecting platforms 22 are respectively longitudinally limited and slid in the connecting limiting groove 19. Multiple locking pins 23 are respectively fixed on the multiple connecting platforms 22. The locking pins 23 slide between the outer ring of the locking shell 8 and the locking base 9. The locking pins 23 are locked and inserted into the inner locking tongue 5 of the fixed fastening strap 1.

[0063] The working principle and beneficial effects of this embodiment are as follows: By pressing the locking button 20, which is fixed at the upper end of the button operation slide 21, the button operation slide 21 is pressed. The outer wall of the button operation slide 21 is slidably set in the limiting slide groove 18 through the limiting slider, so that the button operation slide 21 can slide longitudinally within the multiple limiting slide grooves 18. Multiple connecting platforms 22 are fixed on the outer wall of the button operation slide 21. The multiple connecting platforms 22 are respectively longitudinally limited and slid in the connecting limiting groove 19, so that the multiple connecting platforms 22 can slide synchronously longitudinally. Multiple locking pins 23 are fixed on the multiple connecting platforms 22, so that the locking pins 23 slide between the outer ring of the locking shell 8 and the locking base 9. The locking pins 23 are locked and inserted into the inner locking tongue 5 of the fixing strap 1, so as to realize the insertion and locking of the fixing strap 1 and the unlocking and locking.

[0064] Example 9:

[0065] like Figure 1 — Figure 11 As shown, an automatic locking structure and locking method for a safety belt with a protective structure are disclosed. A button spring 24 is provided at the lower end of the button operation slide 21. The button spring 24 is sleeved on a spring shaft 25, and the spring shaft 25 is fixed on the locking base 9. The button spring 24 is disposed between the locking base 9 and the button operation slide 21.

[0066] The working principle and beneficial effects of this embodiment are as follows: Because a button spring 24 is provided at the lower end of the button operation slide 21, and the button spring 24 is located between the locking base 9 and the button operation slide 21, the locking button 20 and the button operation slide 21 are always subjected to an upward force for reset, thereby realizing the control of locking; because the button spring 24 is sleeved on the spring shaft 25, and the spring shaft 25 is fixed on the locking base 9, the button spring 24 is stabilized when rotating, preventing it from twisting.

[0067] Example 10:

[0068] A method for automatic locking of a seat belt with a protective structure includes the following steps:

[0069] S1: Install multiple fixing straps 1 on the seat and insert the multiple fixing straps 1 into the automatic locking device 2;

[0070] S2: Press the locking button 11 on the automatic locking device 2 to insert and lock the multiple fixing straps 1;

[0071] S3: The tension adjuster 10 on the rotary automatic locking device 2 tightens the multiple fixing straps 1 simultaneously;

[0072] S4: Reverse rotation of the anti-locking threaded tapered barrel 12 locks and secures the tension adjuster 10;

[0073] S5: During the tightening / loosening process, press the locking button 11 to remove multiple fixing straps 1 for loosening.

[0074] The working principle and beneficial effects of this embodiment are as follows: By locking and adjusting multiple fixed straps 1 in the automatic locking device 2, the outer ends of the multiple fixed straps 1 are locked and fixed on the seat, thereby locking the fixed straps 1 at different angles and directions on the seat. By installing multiple fixed straps 1 in several specific positions and inserting them into the automatic locking device 2 for locking and integration, and by simultaneously adjusting and tightening the multiple fixed straps 1 on the automatic locking device 2, they are secured to the passenger, thus completing the adjustment of the seat belt usage.

[0075] This addresses the issue that while conventional seat belts are more suitable for use in the driver's seat, they are not compatible with racing cars or child seats, and in practice, the body may slip out from the top or bottom of the seat belt. It also solves the problem of the inability to adjust the fit and tension properly, which can cause the person restrained by the seat belt to fall off. Furthermore, it resolves the inconvenience of installing, removing, and replacing seat belts.

[0076] The above description is not intended to limit the present invention, nor is the present invention limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
