[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example 1

[0019] like Figures 1 to 3 As shown, a specific embodiment of the seat bridge assembly interface structure for a car seat described in the utility model includes a seat back bridge 1, which is installed on a seat back frame 5, wherein interface grooves 2 are opened on the left and right sides of the seat back bridge 1, and frame connecting parts 6 are symmetrically arranged on the left and right sides of the seat back frame 5, the interface grooves 2 are buckled on the frame connecting parts 6, and the seat back bridge 1 can slide up and down relative to the frame connecting parts 6, and in addition, a locking mechanism 4 is also arranged in the interface groove 2 to ensure the stability of the seat back bridge 1 after being adjusted into place.

[0020] Furthermore, the locking mechanism 4 includes relatively arranged triangular protrusions, which are respectively installed on the two side walls of the interface groove 2. This design can ensure that after the bridge 1 on the seat back slides into place, it can be stably fixed through the locking effect of the triangular protrusions; in order to improve the stability of the structure, two sets of locking mechanisms 4 are also arranged in the interface groove 2 to ensure that the bridge 1 on the seat back is not easily displaced when subjected to external force.

[0021] In order to facilitate the assembly of the seat back bridge 1 and the frame connecting part 6, the interface groove 2 is designed as a U-shaped structure, which is not only easy to install but also can improve the assembly accuracy.

[0022] In addition, in order to enhance the structural strength of the interface groove 2, support protrusions 3 are equidistantly installed in the interface groove 2, and the support protrusions 3 are set to be U-shaped corresponding to the interface groove 2. This design not only improves the stability of the structure, but also effectively reduces the use of materials and reduces costs.

[0023] In the utility model, the seat back bridge 1, the interface groove 2, the support protrusion 3 and the locking mechanism 4 are all made by injection molding. This process makes the whole structure have higher strength and precision, and also improves the production efficiency.

[0024] The working principle of the utility model is as follows: the seat back bridge 1 is assembled with the frame connecting part 6 of the seat back frame 5 through the interface groove 2. The U-shaped structure design of the interface groove 2 makes the assembly process simple and quick. At the same time, the setting of the supporting protrusion 3 enhances the structural strength of the interface groove 2, ensuring the stability and durability of the entire structure; during the adjustment process, the seat back bridge 1 can slide up and down relative to the frame connecting part 6 to meet the personalized needs of different drivers; the triangular protrusion in the locking mechanism 4 will play a locking role, ensuring that the seat back bridge 1 is fixed in a predetermined position to prevent displacement during driving, thereby ensuring the stability and comfort of the seat.

[0025] The components in this article are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0026] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention, and modifications or deformations without creative labor are still within the scope of protection of the present invention.
