Description

Technical Field

[0001] This utility model belongs to the field of seat technology, and in particular relates to a seat belt buckle structure. Background Technology

[0002] Vehicles are typically equipped with seats, and seat belts are usually fixed to these seats to ensure the safety of users when riding in the vehicle. Seat belts are generally connected using elastic buckles.

[0003] For example, Chinese patent document CN206243125U discloses a seat belt and seat. The seat belt includes a first buckle assembly, which includes a first back strap and a first connecting strap. One end of the first back strap has a first fixing part and the other end has a first buckle. One end of the first connecting strap has a second fixing part and the other end has a first locking member that cooperates with the first buckle. The seat belt also includes a second buckle assembly, which includes a second back strap and a second connecting strap. The second back strap includes a third end and a fourth end. The third end has a third fixing part and the fourth end has a third locking member. One end of the second connecting strap has a fourth fixing part and the other end has a third buckle that cooperates with either the third locking member or the first locking member. When using the seat belt, the user can fasten the first locking member and the third buckle to form a two-point fixation; or the user can fasten the first buckle to the first locking member, the second buckle to the second locking member, and the third buckle to the third locking member to form a half-body fixation.

[0004] In the technical solutions of the aforementioned patent documents, both types of seat belt fixing and removal methods require the user to use both hands simultaneously, which is relatively troublesome. If the fastener and buckle are too tightly connected, they are not easy to separate, and removal will take more time, causing inconvenience in use. Utility Model Content

[0005] The purpose of this invention is to provide a seat belt buckling structure that solves the problem that existing seat belt buckling mechanisms require users to use both hands to disengage the seat belt, which is inconvenient to use.

[0006] To achieve the above objectives, this utility model provides a seat belt fastening structure, including a male buckle and a female buckle that is plugged into and connected to the male buckle. One end of the female buckle has an opening, and a first magnetic element is fixedly disposed inside. One end of the male buckle has a guide portion facing the opening of the female buckle, and the guide portion is plugged into and connected to the opening of the female buckle. A sliding groove is provided on the side of the male buckle, and a locking switch extending out of the sliding groove is provided inside the male buckle. A rotatable second magnetic element is also provided inside the male buckle. Sliding the locking switch within the sliding groove drives the second magnetic element to rotate, causing the second magnetic element to magnetically attract or repel the first magnetic element. The end of the female buckle away from the opening has a first engagement hole, and the end of the male buckle away from the guide portion has a second engagement hole. The first engagement hole and the second engagement hole are respectively connected to the seat belt.

[0007] Furthermore, the second magnetic component includes a rotating component and a magnet, the rotating component being rotatably disposed inside the male buckle, and the magnet being fixedly connected to the rotating component.

[0008] Furthermore, the rotating component is a gear, and the locking switch includes a rack. The rack meshes with the gear, so that when the locking switch slides in the groove, it drives the rotating component to rotate.

[0009] Furthermore, the sliding direction of the locking switch is parallel to the direction of the male buckle inserting into the female buckle; the locking switch includes a connecting plate, the rack is disposed on the connecting plate, and the connecting plate is perpendicular to the end of the locking switch extending out of the slide groove.

[0010] Furthermore, an arc-shaped section is provided between the locking switch extending from the slide groove and the connecting plate, and the arc-shaped section is used to abut against the gear.

[0011] Furthermore, the top side of the female buckle is provided with a receiving groove, the first magnetic component is placed in the receiving groove, the bottom end of the receiving groove and the bottom of the female buckle form an insertion groove, and the guide part is inserted into the insertion groove.

[0012] Furthermore, the inner wall of the female buckle is provided with a protruding elastic positioning member, and the outer wall of the guide part is provided with a corresponding positioning groove. When the guide part is inserted into the insertion groove, the elastic positioning member enters the positioning groove to lock the male buckle and the female buckle.

[0013] Furthermore, the elastic positioning member is provided with a first inclined surface and a second inclined surface. The first inclined surface is provided on the side of the elastic positioning member close to the opening of the female buckle, and the second inclined surface is provided on the side of the elastic positioning member away from the opening of the female buckle.

[0014] Furthermore, the locking switch is located at the end of the male buckle near the guide portion and has a pressing block. When the locking switch is slid to release the connection between the male buckle and the female buckle, the pressing block is moved to abut against the second inclined surface, causing the elastic positioning member to move.

[0015] Furthermore, an elastic element is provided at the end of the male buckle away from the guide portion, and the locking switch located in the male buckle is connected to the other end of the elastic element.

[0016] The seat belt buckle structure provided in this embodiment of the present invention has at least the following technical effects:

[0017] The female buckle has an opening at one end and contains a first magnetic component. The male buckle has a guide portion that inserts into the opening at one end, and a locking switch extending from a groove on its side wall. It also contains a rotatable second magnetic component. When the user slides the locking switch, it drives the second magnetic component to rotate, causing the second magnetic component to attract or repel the first magnetic component, thus locking or separating the male and female buckles. The female buckle has a first engagement hole at the other end, and the male buckle has a second engagement hole at the other end. These holes connect to the seatbelt. When the male and female buckles are locked, the seatbelt is engaged; when they are separated, the seatbelt is disengaged. The user can easily separate the male and female buckles by sliding the locking switch with one hand, making operation simple and convenient. Attached Figure Description

[0030] In one embodiment of the seat belt buckling structure of this utility model, please refer to... Figures 1-5 The seat belt fastening structure includes a male buckle 100 and a female buckle 200 that is plugged into the male buckle 100. One end of the female buckle 200 has an opening 210, and a first magnetic element 220 is fixedly installed inside. One end of the male buckle 100 has a guide portion 110 facing the opening of the female buckle 200, and the guide portion 110 is plugged into the opening 210 of the female buckle. A sliding groove 120 is provided on the side of the male buckle 100, and a locking switch 130 extending out of the sliding groove is provided inside the male buckle 100. A rotatable second magnetic element 140 is also provided inside the male buckle 100. Sliding the locking switch 130 within the sliding groove 120 drives the second magnetic element 140 to rotate, causing the second magnetic element 140 to magnetically attract or repel the first magnetic element 220. The female buckle 200 has a first engagement hole 230 at the end away from the opening 210, and the male buckle 100 has a second engagement hole 150 at the end away from the guide portion 110. The first engagement hole 230 and the second engagement hole 150 are respectively connected to the seat belt.

[0031] Specifically, the female buckle 200 has an opening 210 at one end, with a first magnetic element 220 inside. The male buckle 100 has a guide portion 110 at one end that inserts into the opening 210, a locking switch 130 extending out of a slide groove 120 on its side wall, and a rotatable second magnetic element 140 inside. When the user slides the locking switch 130, it drives the second magnetic element 140 to rotate, causing the second magnetic element 140 to magnetically attract or repel the first magnetic element 220, thereby locking or separating the male buckle 100 and the female buckle 200. The female buckle 200 has a first engagement hole 230 at the other end, and the male buckle 100 has a second engagement hole 150 at the other end. The first engagement hole 230 and the second engagement hole 150 are respectively connected to the seat belt. When the male buckle 100 and the female buckle 200 are locked, the seat belt is connected; when the male buckle 100 and the female buckle 200 are separated, the seat belt is separated. Users can easily separate the male buckle 100 and the female buckle 200 by simply sliding the locking switch 130 with one hand, making the operation simple and convenient.

[0032] Furthermore, the second magnetic component 140 includes a rotating component 141 and a magnet 142. The rotating component 141 is rotatably disposed inside the male buckle 100, and the magnet 142 is fixedly connected to the rotating component 141. Specifically, sliding the locking switch 130 causes the rotating component 141 to rotate, which in turn drives the magnet 142 to rotate, changing the direction of the magnetic poles of the magnet 142.

[0033] Furthermore, the rotating component 141 is a gear, and the locking switch 130 includes a rack 131. The rack 131 meshes with the gear 141, causing the rotating component 141 to rotate when the locking switch 130 slides within the slide groove 120. Specifically, when the locking switch 130 is slidable, the rack 131 moves together, causing the gear 141 meshing with the rack 131 to rotate approximately 180°. This causes the magnetic poles of the magnet 142 fixed on the gear 141 to flip, changing the magnetic attraction between the magnet 142 and the first magnetic component 220 from mutual magnetic attraction to mutual magnetic repulsion. This allows the male buckle 100 to automatically disengage from the female buckle 200, achieving automatic unlocking of the male buckle 100 and the female buckle 200.

[0034] Furthermore, the sliding direction of the locking switch 130 is parallel to the direction in which the male buckle 100 inserts into the female buckle 200. The locking switch 130 includes a connecting plate 132, and a rack 131 is disposed on the connecting plate 132. The connecting plate 132 is perpendicular to the end of the locking switch 130 extending out of the slide groove 120. Specifically, because the connecting plate 132 is perpendicular to the end of the locking switch 130 extending out of the slide groove 120, the moving direction of the rack 131 of the connecting plate 132 is consistent with the sliding direction.

[0035] Furthermore, an arc-shaped section 133 is provided between the locking switch 130 extending from the slide groove 120 and the connecting plate 132. The arc-shaped section 133 is used to abut against the gear 141. Specifically, when the sliding locking switch 130 causes the arc-shaped section 133 to abut against the gear 141, the magnet 142 and the first magnetic element 220 will attract each other. At this time, the guide portion 110 of the male buckle will attract each other near the opening 210 of the female buckle and automatically insert.

[0036] Furthermore, a receiving groove 221 is provided on the top side of the female buckle 200, in which the first magnetic element 220 is placed. The bottom end of the receiving groove 221 and the bottom of the female buckle 100 form an insertion groove 240, and the guide part 110 is inserted into the insertion groove 240. Specifically, the receiving groove 221 prevents the first magnetic element 220 from moving with the change of the magnetic pole of the second magnetic element 140. The insertion of the guide part 110 into the insertion groove 240 enhances the stability of the connection between the male buckle 100 and the female buckle 200.

[0037] Furthermore, the inner wall of the female buckle 200 is provided with a protruding elastic positioning element 250, and the outer wall of the guide portion 110 is provided with a corresponding positioning groove 111. When the guide portion 110 is inserted into the insertion groove 240, the elastic positioning element 250 enters the positioning groove 111 to lock the male buckle 100 and the female buckle 200. Specifically, after the guide portion 110 is inserted into the insertion groove 240, the elastic positioning element 250 of the female buckle engages with the positioning groove 111, further improving the connection strength between the male buckle 100 and the female buckle 200 and ensuring the stability of the buckle structure.

[0038] Furthermore, the elastic positioning member 250 is provided with a first inclined surface 251 and a second inclined surface 252. The first inclined surface 251 is provided on the side of the elastic positioning member 250 near the female buckle opening 210, and the second inclined surface 252 is provided on the side of the elastic positioning member 250 away from the female buckle opening 210. Specifically, because the elastic positioning member 250 is provided with a first inclined surface 251 and a second inclined surface 252, and the first inclined surface 251 and the second inclined surface 252 are arranged opposite to each other, when the guide part 110 extends into the insertion groove 240, it abuts against the first inclined surface 251 to make the elastic positioning member 250 enter the positioning groove 111; when the guide part 110 disengages from the insertion groove 240, it abuts against the second inclined surface 252 to make the elastic positioning member 250 disengage from the positioning groove 111.

[0039] Furthermore, the locking switch 130 has a pressing block 134 located at the end of the male buckle near the guide portion 110. When the sliding locking switch 130 releases the connection between the male buckle 100 and the female buckle 200, it moves the pressing block 134 to abut against the second inclined surface 252, causing the elastic positioning member 250 to move. Specifically, when the sliding locking switch 130 unlocks, it moves the pressing block 134 to abut against the second inclined surface 252, causing the elastic positioning member 250 to be squeezed out of the positioning groove 111. Then, with the help of magnetic repulsion, it ensures that the elastic positioning member 250 is released from the positioning groove 111, thereby separating the male buckle 100 and the female buckle 200 and deactivating the connection.

[0040] Furthermore, an elastic element 160 is provided at the end of the male buckle 100 away from the guide portion 110, and a locking switch 130 located inside the male buckle 100 is connected to the other end of the elastic element 160. Specifically, after sliding the locking switch 130 to compress the elastic element 160 and unlock the male buckle 100 and the female buckle 200, and then releasing the locking switch 130, the restoring force of the elastic element 160 resets the locking switch 130, causing the second magnetic element 140 to return to its initial position.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
