[0027] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0028] As Figures 1 - 3 shown, the present utility model provides a buckle seat which is arranged on a substrate 100 and is used for snap - connecting with a buckle. The substrate 100 can be a bracket, a sheet metal part or a plate - shaped plastic part. The connection method between the buckle seat and the substrate 100 can be divided into welding, bonding, integrally molding or connecting through fasteners according to the different materials of the substrate 100. The material of the substrate 100 and the connection method between the buckle seat and the substrate 100 are not specifically limited herein. The buckle seat includes a seat body 1. The seat body 1 is installed on the substrate 100. The seat body 1 protrudes outwardly with a snap - connecting block 11, and the snap - connecting block 11 is used for snap - connecting with the buckle. The seat body 1 is also provided with a positioning groove 13, and at least part of the buckle is located in the positioning groove 13 and is in contact with the inner side wall of the positioning groove 13. The snap - connecting block 11 includes a snap - connecting guiding portion 111 and a snap - connecting portion 113 which are connected. The snap - connecting portion 113 is perpendicular to the seat body 1. Along the snap - connecting direction of the buckle, the snap - connecting guiding portion 111 gradually moves away from the seat body 1. Since the snap - connecting guiding portion 111 is arranged to gradually move away from the seat body 1 along the snap - connecting direction of the buckle, the assembly force required in the assembly process is less than the disengagement force, thereby reducing the labor intensity in the assembly process. And by providing the positioning groove 13, the buckle is positioned with the buckle seat through the positioning groove 13 during the snap - connecting process, ensuring the relative position between the two, ensuring that the snap - connecting is in place, and improving the qualified rate of the finished product. In addition, the size of the groove wall of the positioning groove 13 in contact with the buckle can be set so that the two are closely fitted, further increasing the disengagement force and further improving the snap - connecting effect of the buckle.

[0029] Further, as Figures 1 - 2As shown, one end of the snap-in introduction part 111 is located on the outer side wall of the base body 1 and extends obliquely away from the base body 1. During the snap-in process, the pressure between the snap and the snap-in introduction part 111 gradually increases until the snap is snap-connected to the snap-in part 113. Since the snap-in part 113 is perpendicular to the base body 1, the disengagement force is much greater than the assembly force during the snap-in process. The top surface of the snap-in introduction part 111 can be set as an inclined surface, a convex curved surface or a concave curved surface. When the top surface of the snap-in introduction part 111 is set as an inclined surface, the assembly force during the snap-in process increases evenly; when the top surface of the snap-in introduction part 111 is set as a convex curved surface, the assembly force during the snap-in process first increases rapidly and then slowly; when the top surface of the snap-in introduction part 111 is set as a concave curved surface, the assembly force during the snap-in process first increases slowly and then rapidly. In this embodiment, considering the processing convenience and operation convenience, the top surface of the snap-in introduction part 111 is preferably an inclined surface, and the assembly force increases evenly during the snap-in process, which helps the assembler quickly familiarize with the change law of the assembly force during the snap-in process and can more accurately judge whether the snap-in is in place according to experience.

[0030] Specifically, please continue to refer to Figures 1 - 2 As shown, the snap block 11 further includes a transition part 112, and the transition part 112 is arranged between the snap-in introduction part 111 and the snap-in part 113. The transition part 112 is arranged parallel to the base body 1, and both ends of the transition part 112 are respectively connected to the snap-in introduction part 111 and the snap-in part 113. By arranging the transition part 112, during the snap-in process, the snap first cooperates with the snap-in introduction part 111, then cooperates with the transition part 112, and finally is snap-connected to the snap-in part 113. The corresponding assembly force first increases evenly and then remains unchanged, and finally decreases to 0. By arranging the transition part 112, the operator is more sensitive to the change of the assembly force during the snap-in process, so it is easier to judge whether the assembly is in place. In addition, by arranging the transition part 112, the structural strength of the snap-in part 113 can be further enhanced, and the snap-in part 113 can be prevented from being locally damaged under an external force less than the disengagement force, resulting in accidental disengagement of the snap.

[0031] Furthermore, as Figures 1 - 3 shown, along the snap-in direction of the snap, the positioning groove 13 is provided with a positioning introduction part 131 and a positioning part 132. The positioning introduction part 131 is a chamfer structure for guiding at least part of the snap into the positioning part 132. The positioning part 132 includes two parallel side walls for fitting with at least part of the snap. A positioning block is correspondingly arranged on the snap. During the snap-in process, the positioning block is first placed in the positioning introduction part 131 and is guided into the positioning part 132 through the positioning introduction part 131, and then fits with the two parallel side walls of the positioning part 132, so as to realize positioning, ensure the relative position accuracy between the snap and the snap base during the snap-in process, and ensure that the snap-in is in place.

[0032] Specifically, the positioning groove 13 is further provided with a receiving portion 133. The receiving portion 133 is located at one end of the positioning portion 132 away from the positioning and guiding portion 131. That is, along the clamping direction of the buckle, the positioning groove 13 is sequentially provided with a positioning and guiding portion 131, a positioning portion 132, and a receiving portion 133. The width of the receiving portion 133 is greater than the width of the positioning portion 132. During the clamping process, the positioning block of the buckle passes through the positioning portion 132 and fits with the two side walls of the positioning portion 132. When the clamping is in place, the receiving portion 133 is used to receive the part of the positioning block of the buckle that penetrates out of the positioning portion 132, so as to provide a certain buffer space in the clamping direction of the buckle at the moment when the buckle is clamped with the clamping portion 113 when the clamping is in place, and avoid the problem that the clamping cannot be in place due to the manufacturing precision error of the buckle or the buckle seat.

[0033] Optionally, in this embodiment, both the positioning groove 13 and the clamping block 11 are provided at one end of the seat body 1 away from the substrate 100. The clamping block 11 is provided with two, and the two clamping blocks 11 are respectively located on both sides of the positioning groove 13 to further ensure the clamping effect and balance the force on the buckle seat. When at least part of the buckle fits with the positioning portion 132, the buckle is clamped with the clamping portion 113. Those skilled in the art can set the sizes of the clamping groove and the clamping block 11 according to the structure and size of the buckle. Specific size examples cannot be exhausted, so they will not be listed one by one in this embodiment.

[0034] Furthermore, please refer to Figure 2 As shown, the seat body 1 is provided with a hollow structure and forms an opening 10. The opening 10 is communicated with the positioning groove 13. By hollowing out the seat body 1, a deformation space is provided for the clamping block 11 during the clamping process, and the assembly force required during the clamping process is further reduced. An outer end face 101 is further formed on one side of the seat body 1 where the opening 10 is provided. The outer end face 101 is used to fit with the buckle. When the buckle is clamped with the buckle seat, the outer end face 101 can fit with the corresponding end face of the buckle, so as to limit the buckle, so as to ensure that the buckle will not move greatly in the clamping direction of the buckle after being clamped with the buckle seat. Since the seat body 1 is provided with a hollow structure, the local structural strength is low. Therefore, a reinforcing rib 12 is further provided inside the seat body 1. The reinforcing rib 12 is used to connect the seat body 1 and the substrate 100, so as to strengthen the structural strength of the connection between the seat body 1 and the substrate 100.

[0035] Specifically, the reinforcing rib 12 includes a longitudinal rib 121 and a plurality of transverse ribs 122. The longitudinal rib 121 is fixedly connected to both the seat body 1 and the substrate 100 at the same time, and the longitudinal rib 121 extends along the length direction of the seat body 1. The transverse ribs 122 are perpendicular to the longitudinal rib 121. A plurality of transverse ribs 122 are respectively arranged on both sides of the longitudinal rib 121, and both ends of the transverse ribs 122 are fixedly connected to the longitudinal rib 121 and the seat body 1 respectively. Both the transverse ribs 122 and the longitudinal rib 121 are arranged as plate-like structures. The longitudinal rib 121 is perpendicular to the substrate 100, and the transverse ribs 122 are parallel to the substrate 100. The longitudinal rib 121 and a plurality of transverse ribs 122 together form a framework structure to support the seat body 1, strengthening the structural strength of the seat body 1 while also ensuring the structural strength at the connection position between the seat body 1 and the substrate 100. In other embodiments, multiple parallel longitudinal ribs 121 can also be provided according to requirements, and a plurality of transverse ribs 122 are arranged correspondingly and staggeredly to be applicable to seat bodies 1 of different size specifications.

[0036] Please refer to Figures 1 - 3 As shown, the snap seat in this embodiment further includes a first reinforcing plate 2 and a second reinforcing plate 3, and the first reinforcing plate 2 and the second reinforcing plate 3 are arranged outside the seat body 1. There are two groups of the first reinforcing plates 2, and the two groups of the first reinforcing plates 2 are respectively arranged on both sides of the opening 10 of the seat body 1. The first reinforcing plate 2 is used to connect the seat body 1 and the substrate 100 to strengthen the structural strength between the seat body 1 and the substrate 100, and the first reinforcing plate 2 extends along a first direction on the substrate 100. The number of each group of the first reinforcing plates 2 can be 1, 2, 3, or 4, and one is preferably selected in this embodiment. The second reinforcing plate 3 is arranged on the back of the seat body 1, and the second reinforcing plate 3 is used to connect the seat body 1 and the substrate 100 to strengthen the structural strength between the seat body 1 and the substrate 100. The number of the second reinforcing plates 3 is set to three, and the three second reinforcing plates 3 are arranged in parallel. The second reinforcing plate 3 extends along a second direction on the substrate 100, and the first direction is perpendicular to the second direction. By providing the first reinforcing plate 2 and the second reinforcing plate 3, the structural strength between the seat body 1 and the substrate 100 is further strengthened.

[0037] When using the buckle base in this embodiment to be snap-connected with the buckle, first preliminarily align the buckle with the buckle base, and push the buckle into the buckle base along the snap-connection direction of the buckle, so that at least part of the buckle is located in the positioning and guiding portion 131 of the positioning groove 13 and is guided to the positioning portion 132. During this process, the buckle cooperates with the snap-connection guiding portion 111 of the snap-connection block 11. Continue to push the buckle along the snap-connection direction of the buckle, and the buckle is positioned with the snap-connection portion 113, so that the buckle will not move along the direction perpendicular to its snap-connection direction. During this process, the buckle cooperates with the snap-connection guiding portion 111 and the transition portion 112 in sequence. Continue to push the buckle. At the moment when the buckle cooperates with the snap-connection portion 113, at least part of the buckle passes through the positioning portion 132 and is located in the accommodation portion 133. At this time, within the allowable error range, the buckle cooperates with the snap-connection portion 113, and the outer end face 101 is in contact with the buckle, thus completing the snap-connection of the buckle. During the entire snap-connection process, the assembly force is less than the disengagement force, reducing the labor intensity. At the same time, the actions during the snap-connection process are accurate, which can ensure that the snap-connection is in place and improve the qualified rate of the finished product.
