Figure 2 This is a schematic structural diagram of the telescopic assembly of the first embodiment of the present utility model. Figure 3 This is a schematic structural diagram of the adjustment assembly of the first embodiment of the present utility model. Figure 4 It is a structural schematic diagram of the installation component of the first embodiment of the utility model. The utility model provides a telescopic folding backrest, including a support frame 101, a telescopic component, an adjustment component, a mounting component and an auxiliary component. The telescopic component includes a lower fixed seat 102, a limit rod 103, an upper fixed seat 104, a flat tube 105 and a fixing bolt 106. The adjustment component includes an adjustment seat 107, a rotating seat 108, an adjustment frame 109, a mounting plate 110 and a back pad 111. The installation component includes a mounting frame 112, a spring pin 113 and a limit block 114. The auxiliary component includes a protective shell 115 and a cargo plate 116. The above-mentioned solution solves the problem that the motorcycle backrest cannot be raised or lowered during use, and the backrest cannot be closely fitted to the driver's back, resulting in reduced riding comfort.

[0021] According to this specific embodiment, the lower fixing seat 102 is fixedly connected to the support frame 101 and is located at the top of the support frame 101. There are two limiting rods 103, and the two limiting rods 103 are respectively fixedly connected to the lower fixing seat 102 and are respectively located at the top of the lower fixing seat 102. The upper fixing seat 104 is detachably connected to the limiting rods 103 and is located at the top of the lower fixing seat 102. The flat tube 105 is slidably connected to the lower fixing seat 102 and the upper fixing seat 104 and passes through the lower fixing seat 102 and the upper fixing seat 104. The fixing bolt 106 is slidably connected to the upper fixing seat 104 and passes through the upper fixing seat 104 and the flat tube 105. The adjusting assembly is connected to the flat tube 105. The mounting assembly and the auxiliary assembly are respectively connected to the support frame 101. The support frame 101 is an integral backrest. Providing a supporting effect, the lower fixed seat 102 provides a supporting effect for the telescopic assembly, the limiting rod 103 is used to limit and fix the position of the upper fixed seat 104, and the upper fixed seat 104 is fixed to the outside of the limiting rod 103 by the mounting bolts at its top, and the flat tube 105 provides a supporting effect for the adjusting assembly, and the fixing bolt 106 is used to fix the position of the flat tube 105. When it is necessary to adjust the height of the adjusting assembly, the fixing bolt 106 is loosened to release the fixing of the flat tube 105 by the fixing bolt 106, so that the flat tube 105 can slide inside the lower fixed seat 102 and the upper fixed seat 104. After sliding to the required height, the fixing bolt 106 is tightened to fix the position of the flat tube 105 to prevent the flat tube 105 from sliding during use and causing the back pad 111 to move downward.

[0022] Among them, the adjustment seat 107 is fixedly connected to the flat tube 105 and is located at the top of the flat tube 105, the rotating seat 108 is rotatably connected to the adjustment seat 107 and is located in the middle of the adjustment seat 107, the adjustment frame 109 is fixedly connected to the rotating seat 108 and is located on the outside of the rotating seat 108, the adjustment seat 107 provides support and rotation for the rotating seat 108, and a positioning bead is provided between the rotating seat 108 and the adjustment seat 107 to facilitate limiting the position of the rotating seat 108, so that the rotating seat 108 can be fixed at a position of 0° or 90° to the adjustment seat 107, and the adjustment frame 109 provides support for the mounting plate 110.

[0023] Secondly, the mounting plate 110 is detachably connected to the adjustment frame 109 and is located on the side of the adjustment frame 109 away from the rotating seat 108. The back pad 111 is fixedly connected to the mounting plate 110 and is located on the outer side of the mounting plate 110. The mounting plate 110 provides support for the back pad 111. Bolts passing through the mounting plate 110 are provided between the mounting plate 110 and the back pad 111, which makes it easy to fix the mounting plate 110 and the back pad 111 on the outer side of the adjustment frame 109 during installation.

[0024] Again, the mounting bracket 112 is rotatably connected to the support bracket 101 and is located on the outside of the support bracket 101. There are two spring latches 113, and the two spring latches 113 are fixedly connected to the mounting bracket 112 respectively and pass through the mounting bracket 112 and the support bracket 101 respectively. There are two limit blocks 114, and the two limit blocks 114 are fixedly connected to the mounting bracket 112 respectively and are located at the bottom of the support bracket 101 respectively. The mounting bracket 112 provides support and rotation for the support bracket 101. The mounting bracket 112 is fixed to the top of the motorcycle by bolts. The spring latch 113 is used to limit the position of the support bracket 101. When the spring latch 113 is pulled out, the support bracket 101 can be rotated along the mounting bracket 112 to facilitate the folding of the backrest. The limit blocks 114 are used to support the position of the support bracket 101.

[0025] Finally, there are multiple protective shells 115, and the multiple protective shells 115 are detachably connected to the mounting frame 112 and the adjustment seat 107, and are respectively located on the outside of the mounting frame 112 and the adjustment seat 107. The loading plate 116 is fixedly connected to the mounting frame 112 and is located on the outside of the mounting frame 112. The protective shells 115 are used to protect each rotating part to prevent dust from entering the rotating part and affecting the rotation adjustment of the device. The loading plate 116 makes it easy to carry items on the motorcycle.

[0026] When using the telescopic folding backrest of this embodiment, the support frame 101 provides support for the backrest as a whole, the lower fixed seat 102 provides support for the telescopic assembly, the limiting rod 103 is used to limit and fix the position of the upper fixed seat 104, and the upper fixed seat 104 is fixed to the outside of the limiting rod 103 by the mounting bolts at its top. The flat tube 105 provides support for the adjustment assembly, and the fixing bolt 106 is used to fix the position of the flat tube 105. When the height of the adjustment assembly needs to be adjusted, the fixing bolt 106 is used to fix the position of the flat tube 105. The fixed bolts 106 are loosened to release the fixing of the flat tube 105 by the fixing bolts 106, so that the flat tube 105 can slide inside the lower fixing seat 102 and the upper fixing seat 104. After sliding to the required height, the fixing bolts 106 are tightened to fix the position of the flat tube 105, thereby preventing the flat tube 105 from sliding during use and causing the back pad 111 to move downward. This solves the problem that the motorcycle backrest cannot be raised or lowered during use, and cannot fit closely with the driver's back, resulting in reduced riding comfort.
