It should be understood that the present utility model uses the terms "first", "second", etc. to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0042] In the first aspect, as Figures 1-6As shown in the figure, an embodiment of the present application provides a vehicle backrest, which includes a bracket 1. The bracket 1 includes two symmetrically arranged and spaced-apart first frames 11 and second frames 12, and a connecting frame 13 connected between the first frame 11 and the second frame 12; a backrest body 2 provided on one side of the bracket 1; a decorative cover 3 provided on the other side of the bracket 1. The decorative cover 3 is detachably installed on the side of the backrest body 2 facing the bracket 1, and an installation cavity 4 is formed between the two; at least three fasteners arranged in a triangle are provided in the installation cavity 4 (the triangular arrangement can improve the firmness of the installation structure) for installing the backrest body 2 on the bracket 1; the first frame 11 and the second frame 12 penetrate upward from the bottom of the installation cavity 4 into the installation cavity 4. At least three clamping members arranged in a triangle are provided on the side of the decorative cover 3 facing the bracket 1. Elastic limiting members corresponding to the clamping members are provided on the side of the backrest body 2 facing the bracket 1. The clamping members pass through the bracket 1 and are inserted into the elastic limiting members to install the decorative cover 3 on the backrest body 2, and part of the inner side wall of the decorative cover 3 is pressed against the outer side wall of the backrest body 2. The first frame 11 and the second frame 12 located outside the installation cavity 4 are used to install the backrest on the vehicle 6.

[0043] When the user installs this backrest, first assemble the backrest, that is, install the backrest body 2 on the bracket 1 composed of the first frame 11, the second frame 12, and the connecting frame 13 through fasteners (there are at least three fasteners and they are arranged in a triangle, which can improve the connection strength between the backrest body 2 and the bracket 1). Then, pass the clamping members provided on the decorative cover 3 through the bracket 1 and insert them into the corresponding elastic limiting members, thereby realizing the detachable installation of the decorative cover 3 on the backrest body 2 (there are also at least three clamping members and limiting members, which improve the connection strength between the decorative cover 3 and the backrest body 2). The setting of the elastic limiting members can effectively filter the vibration generated during the vehicle driving process, thereby ensuring the reliable connection between the decorative cover 3 and the backrest body 2. Subsequently, install the first frame 11 and the second frame 12 located outside the installation cavity 4 on the vehicle 6, and finally complete the assembly process of the backrest. The backrest installation method in this solution is simple and can be disassembled and installed separately in the whole vehicle state, which is convenient for the operation and use of market users.

[0044] In some embodiments of the present application, as Figure 3 , Figure 4 shown, an installation platform 31 is provided on the side of the decorative cover 3 facing the bracket 1. The clamping member includes a clamping post 32 provided on the installation platform 31. Part of the circumference of the end of the clamping post 32 away from the decorative cover 3 protrudes radially outward to form a check portion 33.

[0045] When the user installs the decorative cover 3, the clamping member is first aligned with the corresponding limiting member, and then the clamping member is inserted into the corresponding elastic limiting member, so as to complete the installation between the decorative cover 3 and the backrest body 2. The check portion 33 is provided to limit the clamping member from withdrawing from the elastic limiting member, so as to ensure the reliable and firm installation between the decorative cover 3 and the backrest body 2.

[0046] In some embodiments of the present application, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 shown, the backrest body 2 includes a leaning portion 21 and a backrest bottom plate 22 provided on one side of the leaning portion 21 facing the bracket 1 and spaced from the leaning portion 21; a flexible filling member, such as a sponge block, is provided between the leaning portion 21 and the backrest bottom plate 22 to improve the comfort of the occupant; a limiting hole 23 is provided through the backrest bottom plate 22 in the thickness direction, and the elastic limiting member includes a columnar elastic member 24 coaxially inserted into the limiting hole 23, and opposite ends of the columnar elastic member 24 respectively protrude from both ends of the limiting hole 23; a through hole 25 for interference fit installation with the clamping column 32 is coaxially provided in the columnar elastic member 24, the clamping column 32 is inserted into the through hole 25, and the mounting table 31 abuts against one end of the columnar elastic member 24, and the check portion 33 abuts against the other end of the columnar elastic member 24 on the side facing the mounting table 31. When setting the check portion 33, the side of the check portion 33 facing the mounting table 31 is set to a flat structure, and the outer periphery of the side of the check portion 33 facing away from the mounting table 31 is set to a chamfered structure. When the user installs the decorative cover 3, the clamping column 32 is aligned with the corresponding limiting member, and then the clamping column 32 is inserted into the corresponding elastic limiting member. Since the check portion 33 protrudes radially from the clamping column 32, when the clamping column 32 is inserted into the through hole 25, the protruding check portion 33 squeezes the columnar elastic member 24. The front end of the check portion 33 is set to a chamfered shape, which is convenient for the clamping member to be inserted into the limiting member, so that the check portion 33 protrudes from the other end of the through hole 25. At this time, the flat structure of the check portion 33 abuts against the side of the columnar elastic member 24 facing away from the mounting table 31, thereby realizing the limitation of the clamping column 32, so as to prevent the clamping column 32 from withdrawing from the through hole 25 of the columnar elastic member 24 and ensure the reliable installation between the decorative cover 3 and the backrest body 2.

[0047] In some embodiments of the present application, such as Figure 6As shown in the figure, a first annular elastic member 26 is integrally provided coaxially on one side of the columnar elastic member 24 facing the decorative cover 3, and a second annular elastic member 27 is integrally provided coaxially on the other side of the columnar elastic member 24; the first annular elastic member 26 abuts against one side wall of the backrest bottom plate 22 facing the decorative cover 3, and the second annular elastic member 27 abuts against one side wall of the backrest bottom plate 22 facing the leaning portion 21; when the installation between the decorative cover 3 and the backrest body 2 is completed, the installation table 31 abuts against the first annular elastic member 26, and the one side of the check portion 33 facing the installation table 31 abuts against the second annular elastic member 27.

[0048] In order to avoid the vibration generated during the driving of the vehicle 6 from affecting the connection stability between the decorative cover 3 and the backrest body 2, a first annular elastic member 26 and a second annular elastic member 27 are integrally provided coaxially at opposite ends of the columnar elastic member 24, and the first annular elastic member 26 abuts against one side wall of the backrest bottom plate 22 facing the installation table 31, and the second annular elastic member 27 abuts against one side wall of the backrest bottom plate 22 facing away from the installation table 31. When the clamping post 32 is installed in place, the check portion 33 extends out of the second annular elastic member 27, and the flat structure portion of the check portion 33 abuts against the end face position of the second annular elastic member 27, and the installation table 31 abuts against the end face position of the first annular elastic member 26. Since the installation table 31 and the check portion 33 abut against the elastic first annular elastic member 26 and the second annular elastic member 27 respectively, the vibration generated during the driving of the vehicle 6 can be effectively filtered, thereby reducing the influence of the vibration of the vehicle 6 on the clamping post 32, so as to improve the stability and reliability of the assembly connection between the clamping post 32 and the columnar elastic member 24, and further improve the firm installation between the decorative cover 3 and the backrest body 2.

[0049] In some embodiments of the present application, as Figure 4 shown, a slot 34 is provided along the radial direction on one axial side of the clamping post 32, and the slot 34 divides the check portion 33 into at least two parts. The setting of the slot 34 realizes the weight reduction effect on the one hand, and is beneficial to optimizing the casting process of the clamping post 32. That is, when the clamping post 32 is cast, due to the setting of the slot 34, the clamping post 32 will not be deformed structurally. At the same time, the setting of the slot 34 divides the check portion 33 into at least two parts, that is, the check portion 33 is separated into multiple parts. When the check portion 33 enters the through hole 25, the check portion 33 will contract toward the slot 34 position under the extrusion of the inner wall of the through hole 25. That is, the setting of the slot 34 provides a space margin for the check portion 33 to contract when it is inserted into the through hole 25 under the extrusion of the inner wall of the through hole 25, so as to facilitate better insertion of the clamping post 32 into the through hole 25.

[0050] In some embodiments of the present application, the columnar elastic member 24, the first annular elastic member 26, and the second annular elastic member 27 are all made of elastic rubber. Of course, they can also be made of other materials with elasticity and damping effects.

[0051] In some embodiments of the present application, as Figure 1 shown, the fastener includes a first bolt 28 installed on the backrest bottom plate 22. There is a first mounting hole 15 at the middle position of the connecting frame 13 (a connecting plate is provided at the middle position of the connecting frame 13 and the first mounting hole 15 is provided on the connecting plate). At least one second mounting hole 16 is respectively provided on the first frame body 11 and the second frame body 12 (connecting plates are also respectively installed on the first frame body 11 and the second frame body 12 and the second mounting hole 16 is provided on the connecting plate). The first bolt 28 is respectively inserted into the corresponding first mounting hole 15 and second mounting hole 16 and extends out from the other end. A nut 17 is fitted to the extending end of the first bolt 28 to lock the first bolt 28, thereby realizing the installation of the backrest body 2 on the bracket 1.

[0052] In some embodiments of the present application, as Figure 3 shown, a first through hole 5 for the first frame body 11 and the second frame body 12 to pass through is provided at the bottom of the decorative cover 3. When the backrest body 2 and the decorative cover 3 are installed, the lower ends of the first frame body 11 and the second frame body 12 extend out of the installation cavity 4 from the first through hole 5 and are fixedly connected to the vehicle 6. Or holes are provided at the bottom of the decorative cover 3 and the bottom of the backrest body 2, and the two holes cooperate to form the first through hole 5. Or the first through hole 5 is provided at the bottom of the backrest body 2. When the two are assembled, the first frame body 11 and the second frame body 12 are inserted into the installation cavity 4 from bottom to top through the first through hole 5.

[0053] In some embodiments of the present application, in order to further improve the structural strength of the bracket 1, a reinforcing member 14 is connected between the first frame body 11 and the second frame body 12 located outside the installation cavity 4.

[0054] In a second aspect, as Figures 7-9 shown, the present utility model provides a vehicle 6, which is a two-wheeled vehicle, such as an electric vehicle, a motorcycle, etc. It includes the vehicle backrest in the above embodiments.
