Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a foreign object protection car seat belt buckle and vehicle. Background Technology
[0002] As a safety device fixedly connected to the interior of a car, the seat belt buckle's core function is to ensure passenger safety. After a passenger sits down, the seat belt latch needs to be inserted into the buckle port to form a restraint system through the restraint device, which effectively fixes the occupant's position when the vehicle suddenly decelerates violently.
[0003] However, when not in use, the latch and buckle are separated, causing the buckle port to be exposed to the open environment for a long time. This structural characteristic makes it easy for foreign objects to enter the internal structure of the buckle through the open port, which can lead to malfunctions such as buckle mechanism jamming and locking function failure, affecting the safety performance and reliability of the seat belt buckle.
[0004] In related technologies, seat belt buckles with foreign object protection feature a rotatable baffle at the lock hole position. However, when the seat belt latch needs to be inserted into the buckle lock hole, on the one hand, it is difficult for the user to pry the baffle open, and on the other hand, the baffle needs to be pressed for a long time to open the lock hole during the latch insertion process. At the same time, the baffle is also prone to interference with the latch during the insertion process. Utility Model Content
[0005] This utility model proposes an anti-foreign object car seat belt buckle and vehicle, aiming to at least solve the problem that the anti-foreign object structure of the car seat belt buckle with the anti-foreign object structure is inconvenient to use in the related technology, and that the anti-foreign object structure is easy to interfere with the lock tongue when the lock tongue is inserted into the buckle lock hole.
[0006] In a first aspect, this application provides a foreign object protection car seatbelt buckle, comprising:
[0007] The locking body has retractable components on its opposite two side surfaces, and the retractable components have retractable traction ropes.
[0008] The protective cover has two opposite surfaces that are connected to the retractable assembly via the traction rope, and the protective cover has a groove on the adjacent surface of the surface connected to the traction rope, the groove being adapted to the surface of the locking hole of the locking body.
[0009] The retractable assembly is configured to provide traction to the protective cover via the traction rope so that the protective cover covers the lock hole surface of the latch body.
[0010] In some embodiments, the retractable assembly includes a housing, a rotating shaft, and a spiral elastic element. The housing is disposed on the side surface of the latch body and has an open receiving cavity. The rotating shaft is disposed in the receiving cavity and rotatably connected to the housing. The spiral elastic element is coaxially sleeved on the surface of the rotating shaft for resetting after the rotating shaft rotates. One end of the traction rope is wound around the surface of the rotating shaft and the other end extends outward from the opening of the receiving cavity.
[0011] In some embodiments, the spiral elastic element and the traction rope are spaced apart on the surface of the rotating shaft along the axial direction of the rotating shaft.
[0012] In some embodiments, the spiral elastic element and the traction rope have the same circumferential direction of wrapping around the circumferential surface of the shaft.
[0013] In some embodiments, one end of the spiral elastic element near the rotating shaft is connected to the surface of the rotating shaft, and the other end away from the rotating shaft is connected to the inner wall of the receiving cavity.
[0014] In some embodiments, a partition plate is provided inside the receiving cavity, wherein the rotating shaft passes through the partition plate, and the partition plate is located between the spiral elastic element and the traction rope.
[0015] In some embodiments, the opening of the receiving cavity faces the direction of the lock hole of the latch body.
[0016] In some embodiments, the groove is adapted to the size of the lock hole surface of the latch body. When the protective cover is placed on the lock hole surface of the latch body, the groove completely covers the lock hole surface of the latch body.
[0017] In some embodiments, the protective cover has a protrusion on the surface adjacent to the surface where the groove is located; a gasket is provided in the groove.
[0018] Secondly, this application also provides a vehicle that includes the foreign object protection vehicle seat belt buckle as described in the first aspect embodiment above.
[0019] Compared with the prior art, one or more technical solutions described above in the embodiments of this application have at least the following beneficial effects or advantages:
[0020] The protective cover of the seat belt buckle in this application can be fastened to the locking hole surface at the end of the buckle body. When the user needs to use the seat belt, the protective cover is detached from one end of the buckle body and transferred to the upper or lower end face of the buckle body. Due to the retraction assembly, the retraction assembly provides a certain pulling force to the protective cover via a traction rope. This pulling force is at least greater than the weight of the protective cover. When the protective cover is transferred to the upper or lower end face of the buckle body, it cooperates with the tensile stress provided by the retraction assembly, thereby fixing the protective cover relatively to the upper or lower end face of the buckle body. This frees up one of the user's hands, allowing them to easily insert the seatbelt latch into the lock hole at the end of the buckle body. Simultaneously, the protective cover is fixed to the buckle body, preventing its loss. The cover can also be moved to a position fixed to the upper or lower surface of the buckle body. This effectively prevents interference from the cover during the latch insertion process, making insertion easier. The cover completely covers the lock hole, providing more effective protection and preventing foreign objects from entering.
[0021] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.
[0038] Please see Figures 1 to 5This embodiment provides a foreign object protection car seat belt buckle 10. The seat belt buckle 10 mainly includes a buckle body 100 and a protective cover 200. The buckle body 100 has a retractable assembly 110 on its opposite two side surfaces. The retractable assembly 110 has a retractable traction rope 114. The two opposite surfaces of the protective cover 200 are respectively connected to the retractable assembly 110 through the traction rope 114. The protective cover 200 has a groove 210 on the adjacent surface of the surface connected to the traction rope 114. The groove 210 is adapted to the surface where the locking hole 120 of the buckle body 100 is located. The retractable assembly 110 is configured to provide traction force to the protective cover 200 through the traction rope 114 so that the protective cover 200 covers the surface where the locking hole 120 of the buckle body 100 is located.
[0039] In some embodiments, combined with Figure 2 and Figure 3 As shown, the protective cover 200 can be fastened to the surface of the locking hole 120 at the end of the buckle body 100 for the insertion of the seat belt latch 300. When the user needs to use the seat belt, the protective cover 200 is detached from one end of the buckle body 100 and transferred to the upper or lower end face of the buckle body 100. Due to the arrangement of the retraction assembly 110, the retraction assembly 110 provides a certain pulling force to the protective cover 200 through the traction rope 114. This pulling force is at least greater than the weight of the protective cover 200. When the protective cover 200 is transferred to the upper or lower end face of the buckle body 100, it engages with the retraction assembly 114. The tensile stress provided by 0 allows the protective cover 200 to be relatively fixed on the upper or lower end face of the buckle body 100. This frees up one of the user's hands, making it easier for the user to insert the seat belt latch 300 into the locking hole 120 at the end of the buckle body 100. At the same time, the protective cover 200 can be relatively fixed on the buckle body 100, preventing the protective cover 200 from being lost. When the latch 300 on a seat belt webbing is inserted into the locking hole 120 on the buckle body 100, a restraint system is formed through the restraint device, which effectively fixes the occupant's position and ensures passenger safety when the vehicle suddenly decelerates violently.
[0040] Meanwhile, the protective cover 200 is transferred to the upper or lower end face of the latch body 100 and is relatively fixed thereon. During the process of the latch tongue 300 being inserted into the lock hole 120 of the latch body 100, the interference of the protective cover 200 can be effectively avoided, and the insertion process is more convenient.
[0041] In some embodiments, combined with Figure 2 and Figure 3As shown, when a user arrives at their destination and needs to get out of the vehicle, they can press the button 130 on the surface of the locking hole 120 of the latch body 100 to unlock the latch tongue 300 from the locking hole 120 of the latch body 100. Since the latch tongue 300 is separated from the latch when not in use, the locking hole 120 of the latch body 100 is exposed to the open environment for a long time. This structural characteristic makes it easy for foreign objects to enter the internal structure of the latch body 100 through the open locking hole 120, which can cause the latch body 100 mechanism to jam, the locking function to fail, and other malfunctions, affecting the safety performance and reliability of the latch body 100 at the seat belt end. In addition, the locking holes 120 are all on the top surface of the latch body 100. In the overall vehicle layout of the latch body 100, the top surface of the latch body 100 is mostly flush with the surface of the seat cushion, especially in the rear seats. This makes it easy for small objects (coins, sunflower seed shells, buttons, etc.) to fall into the lock hole 120 on the lock body 100. It is also very difficult for occupants to remove small objects from the lock hole 120. When fastening the seat belt, it is easy for it to be loose or falsely locked. When the car is involved in a collision, it cannot restrain the occupants and will cause injury to the occupants.
[0042] In this embodiment, after the latch 300 is unlocked from the lock hole 120 of the latch body 100, the protective cover 200 is gently moved. At the same time, the protective cover 200 is subjected to tensile stress by the retracting component 110, and the protective cover 200 will automatically reset until the protective cover 200 is relatively fixedly covered on the end face of the lock hole 120 of the latch body 100. In this way, the protective cover 200 can completely cover the surface of the lock hole 120 of the latch body 100, thereby more effectively protecting the lock hole 120 of the latch body 100 and preventing foreign objects from entering the lock hole 120.
[0043] In some embodiments, combined with Figure 4 As shown, the retractable assembly 110 also includes a housing 111, a rotating shaft, and a spiral elastic element 113. The housing 111 is disposed on the side surface of the latch body 100 and has an opening in the receiving cavity 1111. The rotating shaft is disposed in the receiving cavity 1111 and rotatably connected to the housing 111. The spiral elastic element 113 is coaxially sleeved on the surface of the rotating shaft for resetting after the rotating shaft rotates. One end of the traction rope 114 is wrapped around the surface of the rotating shaft and the other end extends outward from the opening of the receiving cavity 1111.
[0044] Optionally, the opening of the receiving cavity 1111 faces the direction of the locking hole 120 of the locking body 100. This arrangement is more conducive to the traction rope 114 providing tension to the protective cover 200, so that the protective cover 200 can completely cover the end face of the locking hole 120 of the locking body 100. The spiral elastic element 113 and the traction rope 114 are spaced apart on the surface of the rotating shaft along the axis of the rotating shaft. The spaced arrangement avoids interference between the spiral elastic element 113 and the traction rope 114, ensuring the smoothness of winding and unwinding the traction rope 114.
[0045] Optionally, the spiral elastic element 113 can be a spiral spring. The spiral elastic element 113 and the traction rope 114 have the same circumferential direction around the rotating shaft. One end of the spiral elastic element 113 near the rotating shaft is connected to the surface of the rotating shaft, and the other end away from the rotating shaft is connected to the inner wall of the receiving cavity 1111. One end of the traction rope 114 is fixed on the rotating shaft. When the traction rope 114 is pulled out, it drives the rotating shaft to rotate. The rotating shaft drives the spiral spring to rotate and accumulate elastic potential energy. When the protective cover 200 moves from the upper or lower end face of the locking body 100, the elastic potential energy of the spiral spring drives the rotating shaft to rotate in the opposite direction, thereby realizing the winding effect of the rotating shaft on the traction rope 114.
[0046] In some embodiments, a partition plate 1112 is provided inside the receiving cavity 1111, wherein the rotating shaft passes through the partition plate 1112, and the partition plate 1112 is located between the spiral elastic element 113 and the traction rope 114. The partition plate 1112 can make the traction rope 114 wind more smoothly when winding or unwinding, and at the same time further avoid the spiral elastic element 113 and the traction rope 114 from interfering with each other.
[0047] In some embodiments, combined with Figure 5 As shown, the protective cover 200 has a groove 210 on the end face of the lock hole 120 of the lock body 100. The shape and size of the groove 210 are adapted to the size of the lock hole 120 of the lock body 100. When the protective cover 200 covers the lock hole 120 of the lock body 100, the groove 210 can completely cover the lock hole 120 of the lock body 100.
[0048] Optionally, a gasket 211 is provided in the groove 210. The gasket 211 can be made of rubber. During the process of the protective cover 200 fastening towards the locking hole 120 of the latch body 100, the rubber gasket 211 provides a buffering force when the protective cover 200 collides with the latch body 100.
[0049] Optionally, a protrusion 220 is provided on the adjacent surface of the protective cover 200 to the surface where the groove 210 is located. The protrusion 220 can be a protrusion and can be provided on two opposite outer surfaces. The protrusion 220 facilitates the removal of the protective cover 200 from the surface where the lock hole 120 of the latch body 100 is located, making it convenient for the user.
[0050] In some embodiments, a vehicle is also provided, the vehicle including a foreign object protection vehicle seat belt buckle as described in the above embodiments.
