[0027] Seat belts are important protective devices on vehicles. When a vehicle collides, they can effectively prevent passengers from experiencing secondary collisions, thereby greatly improving the safety of passengers. At present, according to the Automobile Road Traffic Safety Law, motor vehicle drivers and passengers must use seat belts, which means that passengers need to fasten their seat belts regardless of whether they are sitting in the front or back row.

[0028] In the related art, the buckle of the rear seat belt is designed for convenience of use and often protrudes out of the rear seat cushion. However, this may cause the occupant to collide with the buckle when sitting down, causing pelvic discomfort or even bruises to the occupant.

[0029] See also Figure 1-Figure 3In order to solve the problem that the existing seat belt buckle protrudes from the seat cushion and may cause collision and injury with the occupant, the present application provides a seat belt buckle connection structure 100. The seat belt buckle connection structure 100 includes a fixing assembly 10, a buckle body 20 and an elastic member 30, and a limiting groove 101 is provided on the fixing assembly 10. The buckle body 20 is rotatably connected to the fixing assembly 10, and the surface of the buckle body 20 is connected to a limiting block 21, and the limiting block 21 is correspondingly inserted into the limiting groove 101 and movably engaged with the limiting groove 101, and with the rotation of the buckle body 20, the buckle body 20 can move along the limiting groove 101 through the limiting block 21. The elastic member 30 is arranged between the fixing assembly 10 and the buckle body 20, and is respectively connected to the fixing assembly 10 and the buckle body 20, wherein when the buckle body 20 moves toward the direction of the elastic member 30 and squeezes the elastic member 30, the elastic member 30 has a tendency to push the buckle body 20 to move and reset.

[0030] It is understandable that the present application connects the lock body 20 rotatably to the fixed assembly 10, and limits the moving path of the lock body 20 through the cooperation between the limiting groove 101 and the limiting block 21. When the lock body 20 collides with the body of the occupant, the lock body 20 can move along the limiting groove 101 to achieve an avoidance effect. In addition, since an elastic member 30 is provided between the lock body 20 and the fixed assembly 10, the elastic support of the elastic member 30 can be used to achieve the subsequent movement and reset of the lock body 20, so as to facilitate the snap-fit ​​cooperation between the lock body 20 and the seat belt tongue. In this way, the retractability of the lock body 20 is achieved, thereby greatly improving the comfort and safety of the occupant and the convenience of inserting the seat belt, and the overall structure is simple, which can effectively reduce costs.

[0031] Specifically, the limiting groove 101 and the limiting block 21 are both arranged in an arc shape to realize the rotation of the lock body 20 relative to the fixing assembly 10 to avoid interference. In the initial state, the end of the limiting block 21 will abut against the end of the limiting groove 101 away from the elastic member 30 under the elastic support of the elastic member 30 to achieve a stop, thereby improving the stability of the overall structure.

[0032] In order to further improve the matching performance between the limiting block 21 and the limiting groove 101, it is preferred that the end of the limiting block 21 and the end of the limiting groove 101 are both set to be semicircular.

[0033] In one embodiment, if Figure 2 and Figure 3 As shown, the elastic member 30 is V-shaped. In this way, the elastic member 30 has a simple structure and is easy to shape, which can improve the processing efficiency of the elastic member 30 and reduce the processing cost.

[0034] Further, in one embodiment, if Figure 3As shown, the fixing assembly 10 is provided with a first groove 102, and the lock body 20 is provided with a second groove 201. The elastic member 30 includes a first elastic portion 31 and a second elastic portion 32, and one end of the first elastic portion 31 is connected to one end of the second elastic portion 32. The first elastic portion 31 is accommodated in the first groove 102 and is engaged with the first groove 102, and the second elastic portion 32 is accommodated in the second groove 201 and is engaged with the second groove 201.

[0035] Since the limit groove 101 stops the position of the limit block 21, the elastic member 30 can firmly clamp the first elastic part 31 and the second elastic part 32 in the first groove 102 and the second groove 201 only by relying on its own elastic force. In this way, the overall connection of the elastic member 30 is simpler, which effectively reduces the difficulty of installing the elastic member 30.

[0036] Of course, in other embodiments, the elastic member 30 may also be fixed by welding or bonding.

[0037] In one embodiment, if Figure 2 As shown, the buckle body 20 includes a fixing portion 22 and a connecting portion 23, one end of the connecting portion 23 is connected to the fixing portion 22 and is rotatably connected to the fixing assembly 10 through the fixing portion 22, and the other end is used to engage with the locking tongue of the safety belt. The fixing portion 22 and the connecting portion 23 are arranged at an angle and form an L shape.

[0038] In this way, by providing the fixing portion 22, the contact area between the lock body 20 and the elastic member 30 can be increased, thereby facilitating the connection between the two and helping to improve the connection strength of the overall structure.

[0039] Furthermore, in one embodiment, the lock body 20 and the limit block 21 are an integrally formed structure, so that the connection strength of the limit block 21 can be effectively improved to avoid breakage, thereby improving the reliability of the overall structure.

[0040] Specifically, the second groove 201 is formed in the fixing portion 22, and the limiting block 21 is also connected to the fixing portion 22. The lock body 20 and the limiting block 21 can be integrally formed by steel or the like.

[0041] In one embodiment, if Figure 1-Figure 3 As shown, the fixing assembly 10 includes a fixing plate 11, a fixing seat 12 and a first fastener 13. The first fastener 13 penetrates the fixing seat 12 and the fixing plate 11 to fix the fixing seat 12 and the fixing plate 11. Among them, the limiting groove 101 is opened in the fixing seat 12. In this way, the first fastener 13 can realize a detachable connection between the fixing seat 12 and the fixing plate 11, the connection is firm, and it is conducive to subsequent repair and maintenance, reducing maintenance costs.

[0042] Here, the fixing plate 11 may be a structure such as a vehicle body floor.

[0043] Further, in one embodiment, if Figure 2 As shown, the fixing seat 12 includes a bottom plate 121 and two side plates 122, the bottom plate 121 is connected to the fixing plate 11, the two side plates 122 are arranged at intervals and surround the bottom plate 121 to form a U-shaped groove 1201, the lock body 20 is partially inserted into the U-shaped groove 1201 and is rotatably connected to the two side plates 122. Among them, the limiting groove 101 is opened in one or both of the two side plates 122.

[0044] By rotatably connecting the lock body 20 and the two side plates 122 , the secureness of the installation of the lock body 20 can be further improved, thereby increasing the service life of the seat belt buckle connection structure 100 .

[0045] Specifically, in this embodiment, the two side plates 122 are provided with limit slots 101. The number of limit blocks 21 can be the same as the number of limit slots 101 to further improve the reliability of the guide. Of course, only one limit block 21 can be provided to reduce the processing difficulty and processing cost.

[0046] In one embodiment, if Figure 2 As shown, the two side plates 122 are provided with coaxially arranged first through holes 1202, and the buckle body 20 is provided with a second through hole 202. The safety belt buckle connection structure 100 further includes a second fastener 40, which passes through the first through hole 1202 and the second through hole 202 to connect the buckle body 20 to the side plates 122. In this way, a firm connection between the buckle body 20 and the fixing seat 12 can be achieved.

[0047] Furthermore, in one embodiment, the second fastener 40 and the second through hole 202 are clearance-matched, so that the lock body 20 can rotate around the second fastener 40 relative to the fixing seat 12 .

[0048] However, the present invention is not limited thereto. In other embodiments, the second fastener 40 may be tightly matched with the second through hole 202 , and the lock body 20 may be driven to rotate by the second fastener 40 rotating relative to the fixing seat 12 .

[0049] In one embodiment, if Figure 2 As shown, the side plate 122 is also provided with a step hole 1203, which is coaxially arranged with the first through hole 1202. The end of the second fastener 40 is accommodated in the step hole 1203. In this way, the end of the second fastener 40 can be prevented from protruding from the side plate 122, thereby reducing the probability of interference with other components such as the seat, avoiding collision failure, and improving the safety of the overall structure.

[0050] The present application also provides a vehicle, which includes the seat belt buckle connection structure 100 according to any one of the above embodiments.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
