Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive interior accessories technology, specifically to a protective component for preventing accidental unlocking of a car seat cover fixing buckle. Background Technology
[0002] As a component that comes into direct contact with passengers, car seat covers not only enhance driving comfort and aesthetics, but also need to remain stable during vehicle operation to ensure passenger safety. The performance of the fasteners, which serve as the connection hub between the car seat cover and the seat frame, directly determines whether the cover can be securely installed. Currently, the connection between car seat covers and buckles mainly adopts a snap-fit method. That is, a slot or hole structure is reserved on the inner edge of the car seat cover, and the buckle is designed as a flexible hook or pin component. During installation, external force is used to make the buckle elastically deform. After it enters the slot or hole of the cover, it returns to its original shape to achieve a tight lock and fixation. Most existing car face shields and locking strips use simple mechanical buckle structures, which are fixed by a single limiting or locking method. These buckles have poor anti-accidental activation performance when facing complex usage environments. For example, when the vehicle passes through rough roads or experiences sudden braking, the strong vibration may cause the buckle to shift. When passengers adjust their sitting posture or place items, they may also accidentally activate the buckle, causing it to unlock and thus separating from the car face shield.
[0003] Therefore, a protective component for preventing accidental unlocking of a car seat cover fixing buckle is proposed to address the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a protective component for preventing accidental unlocking of a car seat cover fixing buckle, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An anti-accidental unlocking protection component for a car seat cover fixing buckle includes a U-shaped locking strip plate. A buckling mechanism is provided on the outer side of the U-shaped locking strip plate. The buckling mechanism includes a rubber ring, a moving rod, a limiting cover, and a buckling plate. A protective mechanism is provided on the outer side of the U-shaped locking strip plate. The protective mechanism includes an L-shaped plate, a threaded tube fixedly connected to the outer side of the L-shaped plate, a screw threadedly connected to the inside of the threaded tube, a push rod fixedly connected to the tail end of the screw, a telescopic rod movably engaged inside the L-shaped plate, a limit block fixedly connected to the end of the telescopic rod away from the screw, a return spring fixedly connected to the telescopic rod, and a magnetic pole plate fixedly connected to the side of the limit block near the limit cover.
[0006] As a further optimization of this utility model, a replacement mechanism is provided between the moving rod and the buckle plate. The replacement mechanism includes a connecting column, a flange pipe is fixedly connected to the top of the buckle plate, a slider is fixedly connected to the side wall of the buckle plate, and a sliding groove is provided inside the U-shaped buckle plate.
[0007] As a further optimization of this utility model, the movable rod passes through the top of the U-shaped card strip plate, and the buckle plate is movably connected to the inside of the U-shaped card strip plate through the movable rod.
[0008] As a further optimization of this utility model, the L-shaped plates are symmetrically distributed on the top outer side of the U-shaped card strip plate, and the push rod is movably connected to the outer side of the L-shaped plates.
[0009] As a further optimization of this utility model, the telescopic rod and the return spring are symmetrically distributed between the limiting block and the L-shaped plate, and the push rod is located on the outside of the limiting block.
[0010] As a further optimization of this utility model, the two magnetic pole plates are located on the same plane and are both outside the limiting cover, and the two magnetic pole plates are opposite magnetic poles.
[0011] As a further optimization of this utility model, the connecting column is provided with threads on its outer side, and the connecting column is adapted to the flange pipe, and one end of the slider is slidably connected to the inside of the slide groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, the buckle mechanism set on the outside of the U-shaped buckle plate, the rubber ring can increase the friction and prevent accidental contact from causing the moving rod to move.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0017] Please see Figures 1-6 This utility model provides a technical solution: An anti-accidental unlocking protection component for a car seat cover fixing buckle includes a U-shaped locking bar 1, a buckling mechanism 2 is provided on the outside of the U-shaped locking bar 1, the buckling mechanism 2 includes a rubber ring 21, a moving rod 22, a limiting cover 23 and a buckling plate 24, and a protection mechanism 3 is provided on the outside of the U-shaped locking bar 1. The protective mechanism 3 includes an L-shaped plate 31. A threaded tube 32 is fixedly connected to the outside of the L-shaped plate 31. A screw 33 is threadedly connected inside the threaded tube 32. A push rod 34 is fixedly connected to the tail end of the screw 33. A telescopic rod 35 is movably engaged inside the L-shaped plate 31. A limit block 36 is fixedly connected to the end of the telescopic rod 35 away from the screw 33. A return spring 37 is fixedly connected to the telescopic rod 35. A magnetic pole plate 38 is fixedly connected to the side of the limit block 36 near the limit cover 23.
[0018] Furthermore: the moving rod 22 traverses the top of the U-shaped card plate 1; the buckle plate 24 is movably connected to the inside of the U-shaped card plate 1 via the moving rod 22; the L-shaped plate 31 is symmetrically distributed on the top outer side of the U-shaped card plate 1; the push rod 34 is movably connected to the outer side of the L-shaped plate 31; the telescopic rod 35 and the return spring 37 are symmetrically distributed between the limiting block 36 and the L-shaped plate 31; the push rod 34 is located on the outer side of the limiting block 36; the two magnetic pole plates 38 are on the same plane and are both on the outer side of the limiting cover 23; the two magnetic pole plates 38 are opposite magnetic poles.
[0019] It should be noted that: the U-shaped card strip plate 1 serves as the basic frame, providing an installation carrier for other components. Its internal space is used to accommodate the movement trajectory of the buckle plate 24. The rubber ring 21 wraps around the outside of the moving rod 22, reducing the accidental activation of the buckle by external force impact through elastic buffering, while improving the grip feel. The moving rod 22 passes through the top of the U-shaped card strip plate and links with the buckle plate 24 to realize the unlocking or locking action. Its sliding accuracy directly affects the reliability of the buckle.
[0020] Specifically: the telescopic rod 35 slides inside the L-shaped plate 31, and the return spring 37 provides the return force. When the external force accidentally touches the push rod 34, the return spring 37 buffers and reduces the impact on the latching mechanism 2. The symmetrically distributed structural design ensures that the force on both sides is balanced, avoiding the failure of protection caused by unilateral deviation. The magnetic pole plate 38 has opposite magnetic poles and is set opposite to each other. It uses magnetic attraction to form an additional lock to prevent the push rod 34 from moving accidentally. At the same time, the magnetic attraction can provide feedback during operation, making it easy for users to confirm the protection status. The magnetic pole plate 38 is located outside the limit cover 23, forming a double protection with the latching mechanism 2. The combination of magnetic force and mechanical limit improves the reliability of preventing accidental contact.
[0021] As a further implementation of this solution, a replacement mechanism 4 is provided between the moving rod 22 and the buckle plate 24. The replacement mechanism 4 includes a connecting column 41, a flange pipe 42 is fixedly connected to the top of the buckle plate 24, a slider 43 is fixedly connected to the side wall of the buckle plate 24, and a groove 44 is opened inside the U-shaped buckle plate 1.
[0022] Furthermore, the outer side of the connecting column 41 is provided with threads, and the connecting column 41 is adapted to the flange pipe 42, and one end of the slider 43 is slidably connected to the inside of the slide groove 44.
[0023] It should be noted that the outer thread of the connecting column 41 is compatible with the flange pipe 42. The quick assembly and disassembly of the buckle plate 24 and the moving rod 22 can be achieved by rotation, which facilitates maintenance or replacement of buckle plates 24 of different specifications.
[0024] Workflow: First, the operation of the buckling mechanism 2 is crucial for fixing and removing the seat cover. The buckling mechanism 2 includes a rubber ring 21, a moving rod 22, a limiting cover 23, and a buckle plate 24. The moving rod 22 passes through the top of the U-shaped retaining strip 1, and the buckle plate 24 is movably connected to the inside of the U-shaped retaining strip 1 via the moving rod 22. During daily use, the rubber ring 21 increases friction due to its own properties, effectively preventing the moving rod 22 from slipping accidentally. When the seat cover needs to be fixed, the operator pushes the moving rod 22, causing the buckle plate 24 to move within the U-shaped retaining strip 1, so that it snaps into the corresponding slot of the seat cover, completing the fixing. When disassembling, the moving rod 22 is pulled in the opposite direction, and the buckle plate 24 disengages from the slot. The operation is simple, while the limiting cover 23 always plays a limiting role, ensuring that the moving rod 22 and the buckle plate 24 have stable trajectories during movement. Based on the basic function of the latching mechanism 2, the protection mechanism 3 plays a crucial protective role, preventing accidental unlocking of the latching mechanism. The protection mechanism 3 consists of an L-shaped plate 31, a threaded tube 32, a screw 33, a push rod 34, a telescopic rod 35, a limiting block 36, a return spring 37, and a magnetic pole plate 38. The L-shaped plate 31 is symmetrically distributed on the top outer side of the U-shaped latching plate 1. The push rod 34 is movably connected to the outer side of the L-shaped plate 31. The telescopic rod 35 and the return spring 37 are symmetrically distributed between the limiting block 36 and the L-shaped plate 31. The push rod 34 is located on the outer side of the limiting block 36, and the magnetic pole plate 38 is on the corresponding side, both on the outer side of the limiting cover 23. 38 is a dissimilar magnetic pole. When it is necessary to prevent accidental contact, the operator rotates the push rod 34. The push rod 34 drives the screw 33 to rotate and move inside the threaded tube 32, thereby pushing the limit block 36 to move towards the center. During this process, the telescopic rod 35 slides inside the L-shaped plate 31, and the return spring 37 is compressed. When the limit block 36 moves to the appropriate position, the magnetic pole plates 38 on both sides approach each other, and the dissimilar magnetic poles generate a strong attraction, firmly restricting the buckle plate 24 and preventing the moving rod 22 from being accidentally pushed. To release the protection, the push rod 34 is rotated in the opposite direction. Under the elastic force of the return spring 37, the limit block 36 drives the magnetic pole plate 38 to reset, releasing the restriction on the buckle plate 24. Even with the protection of the protection mechanism 3, the snap plate 24 may still wear out or be damaged after long-term use. At this time, the replacement mechanism 4 plays an important role. The replacement mechanism 4 consists of a connecting column 41, a flange tube 42, a slider 43, and a slide groove 44. The connecting column 41 has threads on its outer side and is compatible with the flange tube 42. One end of the slider 43 is slidably connected to the inside of the slide groove 44. When the snap plate 24 needs to be replaced, first unscrew the connecting column 41 from the flange tube 42, then slide the slider 43 along the slide groove 44 to remove the damaged snap plate 24. Next, align the slider 43 of the new snap plate 24 with the slide groove 44 and insert it. Then, tighten the connecting column 41 and the flange tube 42 through the threaded connection to quickly complete the replacement and ensure the continuous and effective operation of the entire protection mechanism 3.
