[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0037] Example 1: Reference Figures 1-13 A method for adjusting the locking mechanism of an anti-loosening seat belt includes the following steps:

[0038] Move the rotating shaft 1 in the locking mechanism upward so that rotating shaft 1 and rotating shaft 2 clamp the two sides of the seat belt respectively;

[0039] After clamping the seat belt on both sides, if pivot 1 and pivot 2 do not rotate when the seat belt is pulled, then the mechanism adjustment is complete.

[0040] If the rotating shaft 1 rotates when the seat belt is pulled, the length of the insert rod 3 is increased so that it can be inserted and engaged with the gear 4 to fix the rotating shaft 1, thus completing the mechanism adjustment;

[0041] If the rotating shaft 2 rotates when the seat belt is pulled, the length of the insert rod 5 is increased so that it can be inserted and engaged with the gear 6 to fix the rotating shaft 2, thus completing the mechanism adjustment.

[0042] The principle behind the above scheme is as follows:

[0043] Whether pivot 1 and pivot 2 can lock after a vehicle collision determines the safety of the occupants. Therefore, during debugging, pivot 1 can be moved upward to clamp the two sides of the seat belt using pivot 1 and pivot 2, simulating the locking of the seat belt after a vehicle collision. At this time, pull the seat belt and observe whether pivot 1 and pivot 2 rotate. If they do not rotate, the seat belt can be locked by the two pivot parts, that is, the insertion rod 3 and the side wall of the gear 4 are inserted and engaged. When the insertion is engaged, the two sides of the tip of the insertion rod 3 contact the two teeth of the gear 4 respectively, thereby fixing the gear 4. Insertion rod 3 and insertion rod 25 have the same structure. If insertion rod 25 is further engaged with gear 26, the device can be used normally.

[0044] If one of the rotating shaft parts rotates under the pull of the seat belt, the device cannot lock the seat belt. When the rotating shaft 1 rotates, it means that the insert rod 3 is not locked to the gear 4, and the length of the insert rod 3 should be increased. When the rotating shaft 2 rotates, it means that the insert rod 5 is not locked to the gear 6, and the length of the insert rod 5 should be increased.

[0045] The beneficial effects of the above scheme are as follows:

[0046] By checking whether the seat belt can rotate the shaft when locked, the difficulty of safety checks after device startup is reduced, and the location of the plug rod to be adjusted can be quickly determined, thus improving the efficiency of device adjustment.

[0047] If the length of the insertion rod is insufficient to connect with the gear, it indicates that the device has been worn or broken after previous use. By debugging, the user can intuitively determine the location of the faulty part, whether it is the insertion rod or the gear, and replace or repair it accordingly, which greatly improves the safety of the device during use.

[0048] Example 2: Reference Figures 1-13 The locking mechanism also includes: bearing seats 7, with a bearing seat 7 rotatably connected to each of the two side walls of the rotating shaft 1, the bearing seats 7 being slidably connected to the middle of the inclined through groove 8, the inclined through groove 8 being opened on the side wall of the mounting frame 9, the top of the inclined through groove 8 being set away from the rotating shaft 2, and the rotating shaft 2 being rotatably connected to the mounting frame 9.

[0049] The top of the bearing housing 7 is connected to the top wall of the inclined through groove 8 via a spring 10. A gear 4 is connected to each end of the rotating shaft 1. The side wall of the gear 4 is engaged with the tip of the insert rod 3. The other side wall of the gear 4 away from the insert rod 3 is engaged with the driving component. The other end of the insert rod 3 is connected to the end of the push rod 11 away from the gear 4. The push rod 11 is slidably connected to the side wall of the mounting bracket 9. The side of the push rod 11 is connected to the mounting bracket 9 via a tension spring 12.

[0050] The ends of the insertion rod 3 and the push rod 11 are slidably connected, and the side wall of the insertion rod 3 is connected to the push rod 11 by a compression spring.

[0051] The principles and beneficial effects of the above scheme are as follows:

[0052] The end of the seat belt is fixed in the mounting bracket 9, and the bottom of the seat belt contacts the top of the rotating shaft 1. The top of the seat belt is located below the rotating shaft 2. Therefore, when the device is in use, it will be subjected to the pulling force from the occupant. Subsequently, the bottom of the seat belt applies downward pressure to the rotating shaft 1, the bearing seat 7 slides downward relative to the inclined through groove 8, and the spring 10 is stretched.

[0053] When an impact occurs, the pulling force from the occupants increases, which in turn further lengthens the spring 10, thus buffering the impact force generated during the impact.

[0054] After achieving the purpose of buffering, the impact activates the drive component, pushing gear 4 to move towards the top of the inclined through slot 8. This clamps the two sides of the seat belt through the rotating shaft 1 and rotating shaft 2. The contact area between the seat belt and the components during clamping increases, thus preventing it from coming loose from the inside of the device. To further improve the locking effect of the device on the seat belt, the movement of gear 4 finally contacts the tip of the insert rod 3, quickly locking the rotating shaft 1 to prevent it from rotating. As the rotating shaft 1 moves upward, the insert rod 3 drives the push rod 11 to move. To prevent the push rod 11 from locking up during the movement, the insert rod 3 slides upward relative to the push rod 11, the compression spring deforms, and the push rod 11 continues to move away from the rotating shaft 1. The tension spring 12 is compressed, ensuring that the tip of the insert rod 3 is locked to the gear 4.

[0055] Example 3: Reference Figures 1-13 The second insertion rod 5 is slidably connected to the mounting bracket 9. The tip of the second insertion rod 5 is set towards the side wall of the second gear 6. The two gears 6 are respectively fixed at both ends of the rotating shaft 2. The bottom of the second insertion rod 5 is connected to the top of the push block 14. The top of the push block 14 is connected to the mounting bracket 9 through the tension spring 2 13. The chamfer 15 at the bottom of the push block 14 is set away from the insertion rod 3 and is set towards the inclined surface 16. The inclined surface 16 is set on the top block 17 of the push rod 11.

[0056] The principles and beneficial effects of the above scheme are as follows:

[0057] As the push rod 11 moves, the top block 17 moves synchronously. The inclined surface 16 on the top block 17 contacts the chamfer 15 at the bottom of the push block 14, causing the push block 14 to move upward. Simultaneously, the insert rod 2 5 moves upward, and its tip engages with the gear 2 6, locking the rotating shaft 2 2. After the rotating shaft 1 and the rotating shaft 2 2 are locked, the seat belt in the locked state can be further prevented from being pulled, further ensuring the safety of the occupants.

[0058] After locking is completed, the rotating shaft 1 moves downward relative to the inclined through groove 8, the spring 10 resets, the compression spring resets and drives the insertion rod 3 to move and reset. When the compression spring is fully reset, the reset of the tension spring 13 drives the insertion rod 5 to reset and ends its insertion engagement with the gear 6. The insertion rod 5 drives the push block 14 to move downward, the chamfer 15 engages with the push block 14, drives the top block 17 and the push rod 11 to reset, the tension spring 12 resets, the side wall of the gear 4 ends its insertion engagement with the tip of the insertion rod 3, and the rotating shaft 1 and the rotating shaft 2 are in a free state, preparing for the next locking.

[0059] Example 4: Reference Figures 1-13 The mounting frame 9 has a round hole 18 on each side. A fixing tube 19 is coaxially arranged in the round hole 18. The end of the fixing tube 19 is connected to the mounting frame 9. The side wall of the fixing tube 19 is connected to the inner wall of the receiving roller 21 through a coil spring 20. The two ends of the receiving roller 21 are rotatably connected to the side wall of the fixing tube 19 through a limiting plate 22.

[0060] The principles and beneficial effects of the above scheme are as follows:

[0061] The fixed tube 19 is connected to the mounting bracket 9. After an impact or being pulled, the seat belt is pulled outward. The storage roller 21 and the limiting plate 22 rotate in the forward direction relative to the fixed tube 19. The coil spring 20 stores elastic potential energy.

[0062] After the impact or pulling ends, the coil spring 20 resets, causing the storage roller 21 and the limiting plate 22 to reverse relative to the fixed tube 19, thus storing the seat belt. During the storage of the seat belt, the limiting plate 22 can limit both sides of the seat belt to prevent the seat belt from moving during storage or release.

[0063] Example 5: Reference Figures 1-13 It also includes a limiting mechanism, which includes an arc groove 23 and a limiting rod 24. Multiple arc grooves 23 are arranged in a circumferential array on the end face of the limiting plate 22 away from the vehicle driving direction. The ends of multiple limiting rods 24 are connected to the inner wall of the mounting bracket 9. The limiting rods 24 are arranged around the circular hole 18. The other end of each limiting rod 24 is set above the arc groove 23. The axis of each limiting rod 24 is coplanar with the axis of the top of an arc groove 23.

[0064] Each limiting groove has a slider 25 slidably connected in the middle. The end of the limiting piece 26 is rotatably connected to the slider 25. A torsion spring 27 is connected between the limiting piece 26 and the slider 25. One side of the slider 25 is connected to the bottom inner wall of the arc groove 23 through a spring 28. The other end of the limiting piece 26 with the arc groove 29 is set towards the top inner wall of the arc groove 23. The axis of the arc groove 29 is concentric with the axis of the top inner wall of the arc groove 23. The arc groove 29 and the opposite arc groove 23 form a locking hole.

[0065] The top of the slider 25 is connected to the end of the limiting structure 48. The axis of the limiting structure 48 is set parallel to the axis of the fixed tube 19, and the other end of the limiting structure 48 is set away from the mounting bracket 9.

[0066] The principles and beneficial effects of the above scheme are as follows:

[0067] When the seat belt is released too quickly, i.e. when the user pulls the seat belt rapidly, the limiting disc 22 rotates forward to release the seat belt. At this time, the arc groove 23 rotates synchronously, and the slider 25 inside the arc groove 23 rotates synchronously. Under the restriction of the second spring 28, the slider 25 is fixed relative to the arc groove 23. At this time, under the action of centrifugal force, the limiting plate 26 reverses relative to the slider 25, and the arc groove 29 moves upward relative to the mounting bracket 9. The torsion spring 27 twists. When the position of the arc groove 29 is facing the limiting rod 24 on the inner wall of the mounting bracket 9, the arc groove 29 contacts and engages with the limiting rod 24. At this time, in order to increase the buffering capacity of the device, the second spring 28 contracts to a certain extent, and the slider 25 moves relative to the arc groove 23 to prevent the internal parts of the device from being damaged due to the excessive speed of the seat belt being pulled.

[0068] Furthermore, the slider 25 is provided with a limiting structure 48 as in the prior art. The limiting structure 48 can be a limiting rod structure or a limiting block structure. The limiting structure 48 is located in the middle of the path of the limiting piece 26 rotating 180° in the opposite direction. The limiting structure 48 does not interfere with the arc groove 23 while moving synchronously with the slider 25. When the limiting piece 26 reverses relative to the slider 25, the arc groove 29 contacts the limiting rod 24, and the limiting piece 26 contacts the limiting structure 48 to prevent the limiting piece 26 from continuing to reverse. After the seat belt is released, the limiting plate 22 reverses under the elastic force of the coil spring 20. Under the elastic force of the spring 28, the slider 25 moves in the opposite direction relative to the arc groove 23. The continued reversal of the limiting plate 22 causes the arc groove 29 to end its contact with the limiting rod 24. At the same time as the torsion spring 27 reverses and resets, the limiting piece 26 synchronously reverses and resets, preparing for the next limiting.

[0069] Example 6: Reference Figures 1-13 A guide ring 30 is slidably connected to the fixed tube 19, and multiple locking pins 31 are slidably connected to the guide ring 30. The end of the locking pin 31 is connected to the end of the return spring 32 through the mounting plate, and the other end of the return spring 32 is connected to the guide ring 30. The other end of each locking pin 31 is set towards a locking hole.

[0070] The principles and beneficial effects of the above scheme are as follows:

[0071] When a vehicle is involved in a collision, the seat belt releases and cushions the impact force momentarily. Simultaneously, the guide ring 30 slides in the direction of the vehicle's travel and the fixing tube 19. At the moment the seat belt provides cushioning, before the limiting piece 26 rotates, the locking pin 31 is inserted into the locking hole. Since one side of the locking pin 31 contacts the inner wall of the top of the arc groove 23 and the other side contacts the arc groove 29, and at this time the other end of the locking pin 31 slides in cooperation with the arc groove 23, the locking pin 31 quickly ends its contact with the inner wall of the top of the arc groove 23, slides along the arc groove 23, and maintains contact with the arc groove 29. At this time, it can prevent the limiting piece 26 from rotating relative to the slider 25. Furthermore, at the same time as locking, the spring 28 is compressed. During the compression process, it can not only reduce the impact force from the arc groove 29 on the locking pin 31;

[0072] Subsequently, under the elastic force of the coil spring 20 and spring 28 returning to their original positions, one side of the locking post 31 contacts the top inner wall of the arc-shaped groove 29 again, ending the cushioning effect on the seat belt;

[0073] When the locking pin 31 is inserted into the arc-shaped groove 23, the return spring 32 can provide a buffer for the locking pin 31 to prevent the arc-shaped groove 23 from being damaged by excessive impact force.

[0074] Example 7: Reference Figures 1-13 The bottom of the guide ring 30 is connected to the ends of two rods 33. The other end of the rods 33 is slidably connected to the groove 35 on the side of the slider 34. The end of the rod 33 facing the locking post 31 is connected to the end of the spring 36. The other end of the spring 36 is connected to the inner wall of the groove 35. Each side of the slider 34 is connected to an electromagnet 37. The electromagnet 37 is located between the locking post 31 and the rod 33. The bottom of the output shaft of the electromagnet 37 is provided with a slope 38, which faces the rod 33.

[0075] The principles and beneficial effects of the above scheme are as follows:

[0076] After an impact, the rod 33 moves in the direction of vehicle travel due to the sliding connection of the slide groove 35, thereby driving the guide ring 30 to move and simultaneously compressing the spring 36. When the rod 33 contacts the inclined surface 38 at the bottom of the output shaft of the electromagnet 37, the output shaft of the electromagnet 37 is pushed upward, thus preventing the rod 33 from resetting on the other side of the output shaft. Therefore, it can prevent the seat belt from suddenly unlocking after a series of impacts. The guide ring 30 moves while driving the locking pin 31 to move, thereby locking the seat belt. To unlock the seat belt, simply energize the electromagnet 37 and retract its output end. Under the elastic force of the spring 36, the rod 33 resets, thereby resetting the locking pin 31 and unlocking the seat belt, further improving the convenience of unlocking the seat belt. The specific model of the electromagnet is ZYE4-25 / 50L.

[0077] Example 8: Reference Figures 1-13 The bottom of slider 34 is slidably connected to the mounting bracket 9. The middle part of slider 34 is threadedly connected to screw 39. Screw 39 is rotatably connected to mounting bracket 9. The end of screw 39 away from slider 34 is equipped with a toothed disc 40. Multiple tooth groups are evenly spaced on the toothed disc 40. The tooth groups mesh with the irregular teeth 41. The irregular teeth 41 are mounted on the drive shaft 42. The drive shaft 42 is rotatably connected to mounting bracket 9.

[0078] The end of the drive shaft 42 is connected to a gear 3 43, which meshes with an internal gear ring 44, and the internal gear ring 44 is connected to a limiting disk 22.

[0079] The principles and beneficial effects of the above scheme are as follows:

[0080] Since occupants of different weights occupy different amounts of space inside the vehicle, heavier occupants pull on a longer seatbelt, while lighter occupants pull on a shorter one. As the seatbelt is pulled, the internal gear ring 44 rotates synchronously, which in turn drives the gear 43 meshing with it. The gear 43 drives the drive shaft 42, which in turn drives the profiled gear 41. The profiled gear 41 meshes with the gear set on the gear disc 40, causing the gear disc 40 to rotate intermittently. With the cooperation of the mounting bracket 9, the rotation of the screw 39 causes the threaded slider 34 to move away from the mounting bracket 9, thereby increasing the distance between the locking pin 31 and the locking hole. Because of the different weights of the occupants, heavier occupants pull on a longer seatbelt, resulting in a longer locking time for the locking pin 31, thus increasing the cushioning effect of the seatbelt on the occupant. The seat belt pulled by the occupant is short, allowing for quick tightening to prevent injury. Based on common knowledge and the aforementioned principles, the device works by activating upon impact and locking the limiting disc 22 via the locking pin 31. Therefore, those skilled in the art can ensure that the locking pin 31 is released upon impact even when the slider 2 34 moves to its maximum distance from the mounting bracket 9. During impact, the rotation of the drive shaft 42 is in the seat belt's buffer phase, preventing the limiting disc 26 from rotating. If the device malfunctions and the rotation of the limiting disc 26 cannot be avoided, the limiting structure 48 on the slider 25 can prevent it from continuing to rotate. At this time, the locking pin 31 is placed in the arc groove 23 and can fix the limiting disc 22 through contact with the slider 25, thus ending the release of the seat belt and further ensuring the safety of the occupant.

[0081] Example 9: Reference Figures 1-13 The driving component includes: push plate 45, push plate 46, and connecting piece 47. The guide ring 30 is connected to the end of push plate 45 on its side. The other end of push plate 45 is connected to the end of push plate 46 with an inclined baffle plate. Push plate 46 is slidably connected to the mounting bracket 9. The other end of push plate 46 is clearance-fitted with the side wall of gear 4. The two push plates 46 are connected by connecting piece 47. Connecting piece 47 is connected to mounting bracket 9 by tension spring 3.

[0082] The principles and beneficial effects of the above scheme are as follows:

[0083] The upward movement of the rotating shaft 1 can be driven by the other end of the push plate 46. After the impact, the movement of the guide ring 30 drives the movement of the push plate 45, which in turn pushes the end of the push plate 46 connected to the inclined baffle. Subsequently, the other end of the push plate 46 pushes the side of the gear 4, thereby clamping the seat belt. The connecting piece 47 between the two push plates 46 can increase the synchronicity of the movement of the two push plates 46. Since the other end of the push plate 46 is clearance-fitted with the side wall of the gear 4, the rotation shaft 1 can move upwards after the impact. Shaft 1 will move downward for a period of time to cushion the occupant with the seat belt. During the cushioning process, after push plate 2 46 moves into place, it will contact the side of gear 4. Due to the large impact force during the impact, the movement of push plate 2 46 has enough force to drive gear 4 to stop moving downward and then move upward, driving shaft 1 to move and thus cushion the seat belt. After the impact, connecting piece 47 can stretch tension spring 3. After the impact, the tension spring can drive connecting piece 47 to reset, so as to prepare for the next operation.
