[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, the integrated seat back provided in this embodiment of the utility model includes: a supporting plastic part 100 and a soft backrest part 200. The supporting plastic part 100 and the soft backrest part 200 are integrally formed by co-mold injection molding. The back of the supporting plastic part 100 is provided with a mounting seat 110 that is adapted to the backrest bar 300.

[0030] Specifically, the supporting plastic part 100 and the soft backrest part 200 are integrally molded through co-mold injection molding, eliminating the need for separate mold manufacturing and assembly of the supporting plastic part 100, foam part, and leather, thus reducing production costs. In addition, the mounting base 110 is located on the back of the supporting plastic part 100, eliminating the need to install the backrest pad on the backrest bar 300 first, and eliminating the need for separate assembly of buckles, resulting in higher production and assembly efficiency for the seat back.

[0031] In this embodiment of the utility model, the mounting base 110 is provided with an integrally formed connector 112. The connector 112 can be used to cooperate with the decorative shell 500, which can cover the mounting base 110 and serve as decoration, without the need for separate installation of buckles or bolts for assembly and connection.

[0032] See Figure 2 and Figure 3 The mounting base 110 is provided with an arc-shaped groove 111 that is adapted to the backrest bar 300. The backrest bar 300 can be embedded in the arc-shaped groove 111. A recess corresponding to the arc-shaped groove 111 can also be provided on the decorative shell 500, so that the backrest bar 300 fits tightly between the mounting base 110 and the decorative shell 500.

[0033] like Figure 1 As shown, the soft backrest 200 includes an elastic foam layer and a leather layer. The supporting plastic part 100, the elastic foam layer and the leather layer are stacked and joined together in sequence to form an integral structure. The supporting plastic part 100 can be injection molded from modified PP material. During processing, the supporting plastic part 100, the elastic foam layer and the leather layer can be connected into an integral structure using hot pressing, welding and other processes. This makes it easy to process into a shape that conforms to the curve of the human body and can achieve a seamless connection between the supporting plastic part 100, the elastic foam layer and the leather.

[0034] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the installation mechanism provided in this embodiment of the present invention includes a clamping member 400 and an integrated seat back and backrest bar 300 as described in the above embodiments; the clamping member 400 is connected to the mounting base 110, and the backrest bar 300 is connected to the mounting base 110 through the clamping member 400.

[0035] Specifically, the clamping element 400 can be made of metal and formed into an arc-shaped structure that fits the backrest bar 300 by bending or stamping, thereby allowing the clamping element 400 to fit more tightly with the backrest bar 300. In addition, multiple clamping elements 400 can be provided and connected to the mounting base 110 respectively, so that the backrest bar 300 can be pressed and fixed together by the multiple clamping elements 400.

[0036] In this embodiment of the invention, the mounting base 110 is detachably connected to a decorative shell 500. The backrest bar 300 can be detachably connected to the mounting base 110 via bolts or clips. By eliminating the assembly step of tightening bolts, the decorative shell 500 can be clipped onto the connector 112, thus making assembly more convenient.

[0037] Specifically, the interior of the decorative shell 500 is provided with a snap-fit ​​portion 501 that is adapted to the mounting base 110, see [link / reference]. Figure 3 The mounting base 110 has connectors 112 on both the top and bottom sides. See Figure 4 The decorative shell 500 has snap-fit ​​parts 501 on both the top and bottom inside. The connector 112 is matched with the snap-fit ​​parts 501 to ensure that the decorative shell 500 is installed securely.

[0038] See Figure 3 and Figure 4 The decorative shell 500 is provided with a slot 502 that is compatible with the mounting base 110. When installing the decorative shell 500, the connector 112 first engages with the slot 502 to ensure that the decorative shell 500 and the mounting base 110 are accurately aligned. Then, the decorative shell 500 is pressed to make the connector 112 engage with the snap-fit ​​part 501, thereby realizing the assembly of the decorative shell 500 and the mounting base 110.

[0039] like Figure 5 and Figure 6 As shown, the backrest bar 300 is bent and connected to the bracket 600, and the supporting plastic part 100 is connected to the bracket 600. The end of the backrest bar 300 can be inserted into a tube seat, which is bolted to the bracket 600, thus fixing the backrest bar 300 relative to the bracket 600. The back of the supporting plastic part 100 is connected to the backrest bar 300, using the backrest bar 300 to support the back of the supporting plastic part 100. The bracket 600 supports and fixes the bottom of the supporting plastic part 100, ensuring a stable seat back. Furthermore, the backrest bar 300 can be bent and extended to both sides of the seating area, providing protection for the occupant.

[0040] The electric vehicle provided in this embodiment is equipped with the integrated seat back or mounting mechanism described in the above embodiment, and has the technical advantages of the integrated seat back and mounting mechanism, which will not be repeated here.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
