[0022] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Example 1 The vehicle backrest bracket provided in this application can be used on electric bicycles. The backrest is connected to the frame through the vehicle backrest bracket, allowing the rear passenger to lean against the backrest, thus improving the passenger's safety and comfort.

[0024] See Figures 1 to 5 As shown, the vehicle backrest support includes a support frame and a connecting frame. The support frame is used to support and fix the connecting frame, and the support frame and the connecting frame are detachably connected, facilitating the removal and replacement of the backrest. Specifically, the support frame includes a connecting rod 101, which is used to connect to the vehicle frame. Figures 1 to 3 The connecting rod 101 shown is bent into a certain arc to fit the shape of the rear of the frame, thereby forming a wraparound structure set at the rear of the frame. The compactness between the components is higher, and it does not affect the overall appearance and aesthetics of the vehicle.

[0025] Furthermore, the connecting frame includes a first connecting plate 102 and a second connecting plate 103; the first connecting plate 102 includes a slot 104, into which the connecting rod 101 is embedded; the second connecting plate 103 is used to connect the backrest; the second connecting plate 103 is located at the opening of the slot 104, and the second connecting plate 103 penetrates the slot walls on both sides of the slot 104, and the second connecting plate 103 and the slot 104 are tightly clamped to the circumference of the connecting rod 101. The slot 104 and the second connecting plate 103 enclose and clamp the connecting rod 101 between them, forming multi-directional constraints in the axial, radial and torsional directions, thereby effectively preventing problems such as loosening, displacement or detachment between the support frame and the connecting frame, and improving the connection strength and stability between the backrest and the frame.

[0026] Furthermore, the second connecting plate 103 and the slot 104 are connected by an insertion method to secure the connecting rod 101, eliminating the need for complex bolts, welding, or other fixing methods, thus simplifying the installation process and improving assembly efficiency. Moreover, when repairing or replacing the backrest, the second connecting plate 103 can be pulled out of the slot 104 to detach the connecting frame from the support frame, allowing for easy and quick disassembly of the backrest.

[0027] Optionally, adding anti-slip textures or elastic pads to the inner wall of the slot 104 and / or the outer wall of the connecting rod 101 can further enhance friction and anti-slip performance, and improve the stability of the connection between the connecting frame and the support frame.

[0028] In an optional embodiment, the first connecting plate 102 further includes a retaining plate portion 105; the retaining plate portion 105 is connected to the retaining groove portion 104; the top of the second connecting plate 103 is used to connect to the backrest; the middle of the second connecting plate 103 penetrates the groove walls on both sides of the retaining groove portion 104; the bottom of the second connecting plate 103 can abut against a preset side of the retaining plate portion 105.

[0029] In this embodiment, such as Figure 4 As shown, the connecting rod 101 is placed horizontally and embedded in the slot 104. The upper and lower sides of the slot 104 are provided with through holes 106. The through holes 106 are adapted to the cross-section of the second connecting plate 103, and the two through holes 106 are positioned opposite each other. During assembly, the second connecting plate 103 can pass through the two through holes 106 from top to bottom so that the slot 104 and the second connecting plate 103 can tightly clamp the connecting rod 101.

[0030] The slot 104 is located on the side of the connecting rod 101 away from the passenger. The second connecting plate 103 is located between the slot 104 and the passenger, and the second connecting plate 103 passes through the slot 104 and fits against the plate 105. When the passenger leans against the backrest, the top of the second connecting plate 103 tilts outward under force. Figure 3 (The arrow in the image indicates the direction of force). The bottom of the second connecting plate 103 is close to the clamping plate portion 105 so that the clamping plate portion 105 can support the second connecting plate 103, thereby making the first connecting plate 102 and the second connecting plate 103 firmly connected and avoiding problems such as loosening, displacement or falling off between the support frame and the connecting frame.

[0031] In an optional embodiment, the locking plate 105 is provided with a limiting protrusion 107, and the second connecting plate 103 is provided with a limiting hole 108. The limiting protrusion 107 is engaged within the limiting hole 108. The cooperation between the limiting protrusion 107 and the limiting hole 108 provides an additional mechanical locking mechanism to ensure that there is no displacement or loosening between the second connecting plate 103 and the first connecting plate 102, further enhancing the overall stability of the vehicle backrest bracket.

[0032] Furthermore, a guide slope 109 is provided on the side of the limiting protrusion 107 near the slot portion 104, and the second connecting plate 103 can slide along the guide slope 109 and press the limiting protrusion 107 until the limiting protrusion 107 is engaged in the limiting hole 108.

[0033] In this embodiment, the limiting protrusion 107 has slight elasticity. When assembling the first connecting plate 102 and the second connecting plate 103, the second connecting plate 103 contacts and presses the limiting part until the limiting hole 108 aligns with the limiting protrusion 107. The limiting protrusion 107 then resets and embeds itself into the limiting hole 108, thereby locking and fixing the first connecting plate 102 and the second connecting plate 103. The second connecting plate 103 slides along the guide slope 109, allowing it to gradually apply pressure to the limiting part, making the insertion operation of the second connecting plate 103 easier and thus improving assembly efficiency.

[0034] Specifically, such as Figure 4 As shown, the limiting protrusion 107 includes a bending plate 110 and a support block 111; a notch 112 is provided in the middle of the clamping plate portion 105, one end of the bending plate 110 is connected to one side of the notch 112, and the unfolded bending plate 110 is adapted to the notch 112; the bending plate 110 surrounds to form an accommodating space, and the support block 111 is filled in the accommodating space.

[0035] In this embodiment, during actual production, a bending plate can be formed by cutting from the middle of the clamping plate 105. The upper end of the bending plate remains connected to the clamping plate 105. The bending plate is then bent towards the second connecting plate 103 to form a protruding bent plate 110. Only the upper end of the bent plate 110 is connected to the clamping plate 105, allowing the bent plate 110 to spring relative to the clamping plate. A receiving space is formed on the side of the bending plate away from the second connecting plate 103. The support block 111 fills the receiving space, which increases the strength of the bent plate 110 and prevents it from deforming under stress.

[0036] Preferably, elastic clips 113 are provided on both sides of the support block 111. The elastic clips 113 are engaged on the side of the card plate portion 105 near the second connecting plate 103, so that the support block 111 and the bending plate 110 are tightly fixed together.

[0037] In an optional embodiment, the first connecting plate 102 further includes a connecting portion 114; the connecting portion 114 is connected to the end of the retaining plate portion 105 away from the retaining slot portion 104, and the connecting portion 114 is used for connection with the vehicle frame. Figure 4 As shown, the slot portion 104, the plate portion 105, and the connecting portion 114 are structures formed by bending the first connecting plate 102. The plate portion 105 is arranged vertically, and the connecting portion 114 is vertically connected to the bottom end of the plate portion 105. The connecting portion 114 is provided with a connecting hole 115 for connecting to the frame. The frame can support and fix the connecting frame, thereby improving the stability of the overall structure.

[0038] In an optional embodiment, the slot of the slot portion 104 is provided with a locking edge 116, which engages with the side of the second connecting plate 103 opposite to the connecting rod 101. After the second connecting plate 103 passes through the through hole 106 of the slot portion 104 from top to bottom, the locking edge 116 can prevent the second connecting plate 103 from reversing, thereby achieving pre-fixation of the second connecting plate 103 and improving the convenience of installation.

[0039] In the optional solutions of this embodiment, such as Figure 3 and Figure 5 As shown, the second connecting plate 103 is provided with a locking platform 117; the locking platform 117 is engaged with the outer side of the groove wall of the slot portion 104 near the backrest. When the second connecting plate 103 is assembled with the first connecting plate 102, the second connecting plate 103 can pass through the two groove walls of the slot portion 104 from top to bottom. When the locking platform 117 of the second connecting plate 103 engages with the outer side of the upper groove wall, the second connecting plate 103 is installed in place. At this time, the limiting hole 108 at the lower part of the second connecting plate 103 engages with the limiting protrusion 107, thereby forming a two-point locking and positioning structure, improving the stability of the overall structure.

[0040] In an optional embodiment, the connecting frame further includes a reinforcing rib 118; the reinforcing rib 118 is supported on the outer side of the groove wall near the backrest of the slot portion 104, and the reinforcing rib 118 is connected to the second connecting plate 103 to apply a supporting force to the second connecting plate 103.

[0041] In this embodiment, the passenger leans against the backrest from one side of the second connecting plate 103, while the reinforcing rib 118 is located on one side of the second connecting plate 103. The reinforcing rib 118 supports the second connecting plate 103 between the first connecting plate 102, thereby improving the deformation resistance of the second connecting plate 103, helping to maintain the stability and reliability of the connection structure, and thus improving durability. In addition, when assembling the second connecting plate 103 with the first connecting plate 102, in addition to the locking platform 117 of the second connecting plate 103 being able to engage with the outer side of the upper groove wall, the reinforcing rib 118 connected to the second connecting plate 103 can also engage with the outer side of the upper groove wall, so that the reinforcing rib 118 can also play a positioning role.

[0042] Example 2 The vehicle backrest bracket in this second embodiment is an improvement on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this second embodiment.

[0043] In an optional embodiment, the support frame further includes a connecting lug 119; one end of the connecting lug 119 is connected to the connecting rod 101, and the other end of the connecting lug 119 is connected to the vehicle frame. See also Figure 1 and Figure 2As shown, both ends of the connecting rod 101 are provided with connecting ears 119, and one end of the connecting ear 119 is welded to the connecting rod 101. The other end of the connecting ear 119 is provided with a connecting hole 115 to connect with the frame, thereby realizing the detachable connection between the support frame and the frame.
