DETAILED DESCRIPTION
[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0019] Example 1.
[0020] like Figure 1-4As shown, the backrest bracket described in this embodiment includes a left bracket 100 and a right bracket 200, the left bracket 100 has a first mounting portion 10 and a second mounting portion 20 arranged in parallel with each other, the first mounting portion 10 is used to connect with the backrest assembly 300, the second mounting portion 20 is used to connect with the vehicle body frame, and the first mounting portion 10 is connected to the second mounting portion 20 through an inclined transition portion 30; the right bracket 200 has the same structure as the left bracket 100, and reinforcing plates 40 are provided on the surfaces of the right bracket 200 and the left bracket 100 that are away from each other, the reinforcing plate 40 is tightly attached to the outer surface of the corresponding left bracket 100 or the right bracket 200, and has an outer contour consistent with the corresponding left bracket 100 or the right bracket 200.
[0021] When implementing it, Figure 4 As shown, the left bracket 100 and the right bracket 200 are respectively installed on the left and right sides of the backrest assembly 300, wherein each bracket includes two main parts: a first mounting portion 10 and a second mounting portion 20, wherein the first mounting portion 10 is designed to be connected to the backrest assembly 300 of the seat, and the second mounting portion 20 is used to be connected to the vehicle body frame (not shown in the figure), and between the two mounting portions (10, 20), there is a connection through an inclined transition portion 30, such a design allows the backrest bracket to be effectively connected to the backrest assembly 300 and the vehicle body frame even when space is limited, and the inclined setting of the transition portion 30 helps to optimize the mechanical properties of the backrest bracket and provide better support. In addition, a reinforcing plate 40 is provided on the surface of the left bracket 100 and the right bracket 200 that are separated from each other, and the reinforcing plate 40 is closely attached to the outer surface of the bracket and is consistent with the outer contour of the bracket, which not only enhances the overall stability of the structure, but also ensures that the load can be effectively transmitted, that is, the overall design not only ensures strength, but also takes into account the economical use of materials, meeting the design requirements of lightweight vehicles.
[0022] In some embodiments, Figure 2 As shown, in order to improve the torsional rigidity of the backrest bracket, the right bracket 200 and the left bracket 100 are both provided with a skirt structure 50 on the surfaces facing away from each other, and the skirt structure 50 extends outward along the edge of the corresponding left bracket 100 or right bracket 200. With this structural design, when the backrest bracket bears the load from the passenger or external force, the skirt structure 50 provides additional lateral support through its outward extension design, which helps to disperse and transfer the load, reduce the torsional deformation of the bracket, and thus protect the seat structure from damage.
[0023] In some embodiments, Figure 1As shown, the outer edge of the reinforcing plate 40 contacts the inner wall surface of the corresponding skirt structure 50. In this way, the load can be more effectively transferred from the skirt structure 50 to the reinforcing plate 40 through the contact surface, thereby enhancing the bearing capacity of the structure.
[0024] In some embodiments, Figure 2 and Figure 3 As shown, the left bracket 100 and the right bracket 200 are both provided with convex ribs 60, and the convex ribs 60 extend from the first mounting portion 10 to the second mounting portion 20, and the plate surface of the reinforcing plate 40 is provided with a groove structure 41 that matches the shape of the convex ribs 60. In this embodiment, the convex ribs 60 can be used as reinforcing ribs to increase the local rigidity of the backrest bracket in the stress concentration area and reduce bending or deformation. At the same time, the combination of the convex ribs 60 and the groove structure 41 helps to form a more integrated and continuous structure, so as to further improve the overall rigidity and anti-deformation ability of the backrest bracket.
[0025] In addition, if Figure 2 and Figure 3 As shown, the lengths and widths of the corresponding ribs 60 on the left bracket 100 and the right bracket 200 can be set in different styles to meet the installation avoidance requirements of other components in the limited vehicle body space.
[0026] In some embodiments, Figure 4 As shown, in order to balance the load distribution, the second mounting portion 20 is provided with a plurality of mounting holes 70 arranged at intervals in the vertical direction, and the number of mounting holes 70 on both sides of the rib 60 on the second mounting portion 20 is the same. The plurality of mounting holes 70 provide a variety of mounting options, allowing adjustment according to specific vehicle models or installation conditions, improving the flexibility and adaptability of installation, while reducing the reliance on a single connection point, thereby improving the durability and reliability of the entire backrest bracket. In addition, the same number of mounting holes 70 on both sides of the rib 60 helps to more evenly transmit and disperse the torsional force, so as to improve the torsional resistance of the backrest bracket.
[0027] In this embodiment, the mounting holes 70 pass through the reinforcement plate 40. The through mounting holes 70 allow bolts or fasteners to be installed directly through the reinforcement plate 40, thereby providing a more direct and rigid connection.
[0028] In some embodiments, Figure 1 and Figure 2 As shown, in order to improve the overall bearing capacity of the backrest assembly 300, a smooth arc surface 80 is formed at the upper part of the connection between the first mounting portion 10 and the transition portion 30, and a V-shaped notch 90 is formed at the lower part of the connection between the first mounting portion 10 and the transition portion 30. Figure 4The assembly position of the backrest assembly 300 and the first mounting portion 10 is close to the lower edge portion, and a smooth arc surface 80 is formed on the upper portion of the connection between the first mounting portion 10 and the transition portion 30, which can make the force more uniform, reduce fatigue damage of local materials, and improve the overall bearing capacity. The V-shaped notch 90 can reduce the overall weight of the structure while ensuring the structural strength and stability, thereby meeting the demand for lightweight.
[0029] The backrest bracket designed by the utility model, the designed left bracket and right bracket, and the first mounting part and the second mounting part parallel to each other, provide a more reasonable mechanical support structure, enhance the overall stability and durability of the backrest bracket, avoid simply increasing the material thickness to improve the strength of the backrest bracket, and achieve a balance between performance and lightweight without sacrificing safety, meeting the demand for weight reduction in modern automobiles.
