[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0018] See also Figure 1 , Figure 2 As shown, an embodiment of the utility model provides a threshold bracket and threshold skin installation matching structure, including a threshold bracket 1 and a threshold skin 2, the threshold bracket 1 is fixedly installed to the vehicle body, and the threshold skin 2 is covered and installed on the outer side of the threshold bracket 1 to decorate and protect the threshold bracket 1.

[0019] A plurality of claws 3 are arranged at intervals on the inner side of the threshold skin 2 (i.e., the side facing the threshold bracket 1), and a plurality of sockets 4 for inserting the claws 3 are correspondingly arranged on the threshold bracket 1. An elastic movable tongue piece 5 and a static tongue piece 6 are arranged oppositely on the inner edge of the socket 4, and a card interface 7 for the claw 3 to be inserted is formed between the elastic movable tongue piece 5 and the static tongue piece 6. The elastic movable tongue piece 5 is constructed to be able to apply an elastic force to the inserted claw 3 so that it is clamped and fixed with the static tongue piece 6. In other words, when the claw 3 is clamped into the clamp interface 7, the claw 3 can be clamped and fixed with the static tongue piece 6 under the action of the elastic force applied by the elastic movable tongue piece 5, so that the threshold skin 2 is clamped and installed to the threshold bracket 1.

[0020] Specifically, Figure 3 , Figure 4As shown, the elastic movable tongue piece 5 in the embodiment of the utility model includes an integrally formed support portion 51 and a clamping portion 52. The upper end of the support portion 51 is connected to the door sill bracket 1, and the lower end of the support portion 51 extends obliquely downward (i.e., in the direction of the static tongue piece 6) toward the outside of the socket 4; the upper end of the clamping portion 52 is connected to the lower end of the support portion 51, and the lower end of the clamping portion 52 extends obliquely downward (i.e., in the direction of the static tongue piece 6) toward the inside of the socket 4. When the claw 3 is inserted into the card interface 7, the claw 3 can push the clamping portion 52 inward, so that the support portion 51 undergoes elastic deformation so that the claw 3 can be smoothly inserted. At the same time, the clamping portion 52 extending obliquely toward the inside of the socket 4 can also play a guiding role in the insertion of the claw 3; when the claw 3 is successfully inserted, the clamping portion 52 can press the claw 3 under the elastic force of the support portion 51, so that the claw 3 is clamped and fixed with the static tongue piece 6.

[0021] In the embodiment of the utility model, a hook 8 is formed at the end of the claw 3, and the hook 8 protrudes toward one side of the static tongue piece 6, so that after the claw 3 is inserted into the card interface 7, the hook 8 can be engaged with the static tongue piece 6 to prevent the claw 3 from coming out. In order to allow the claw 3 to be smoothly inserted into the card interface 7, a guide slope 81 is designed on the side of the hook 8 away from the door sill skin 2 in the embodiment of the utility model. When the claw 3 is inserted into the card interface 7, the guide slope 81 can abut against the static tongue piece 6, playing a guiding role for the insertion of the claw 3.

[0022] In addition, the embodiment of the utility model is also designed with a slip-off slope 82 on the side of the hook 8 facing the threshold skin 2. When the threshold skin 2 is removed, the slip-off slope 82 abuts against the static tongue piece 6, so that the hook 8 can be gradually lifted up as the claw 3 moves outward, and the support portion 51 is pushed by the claw 3 to undergo elastic deformation so that the claw 3 can be smoothly disengaged. As a specific reference example, in the embodiment of the utility model, the angle a between the clamping portion 52 and the static tongue piece 6 is 38.7°, the guide angle b between the guide slope 81 and the static tongue piece 6 is 60°, and the slip-off angle c between the slip-off slope 82 and the static tongue piece 6 is 10°.

[0023] Compared with the traditional screw-fastening connection, the embodiment of the utility model directly clamps and installs the threshold skin 2 to the threshold bracket 1 through the claws 3, the elastic movable tongue piece 5 and the static tongue piece 6. During assembly, there is no need to use fasteners such as screws and nuts, nor is there any need to use any disassembly and assembly tools, which can effectively improve the installation efficiency and reduce the installation cost. At the same time, since there is no need to set screw fastening points on the threshold skin 2, the threshold skin 2 can be effectively prevented from being deformed due to uneven force during assembly.
