Description

Technical Field

[0001] This utility model belongs to the field of motorcycle technology and relates to a multi-functional motorcycle backrest bracket. Background Technology

[0002] Most motorcycles currently do not have backrests; they only have a tail rack at the rear, which means they cannot provide support for the driver or carry passengers.

[0003] A Chinese utility model patent with publication number CN216709507U describes a foldable motorcycle backrest that includes a cushion, a bracket, and a base. The cushion is fixed to the bracket, the bracket passes through the base, and a folding member is provided at the connection between the bracket and the base. The bracket can be adjusted in angle or folded on the base via the folding member.

[0004] The existing technology has the following technical defects:

[0005] The above technical solution can provide a comfortable riding experience for the driver and can also be laid flat to increase the surface area for transporting goods. However, the above technical solution requires special components to install the base onto the motorcycle's tail rack. Different motorcycle tail racks are not the same, and the installation method is not applicable to most models. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-functional motorcycle backrest bracket.

[0007] The multi-functional motorcycle backrest bracket of this utility model includes two side uprights, with several crossbeams connecting the two side uprights. Several connecting holes and fixing grooves are provided on the crossbeams. Each side upright has an open circular buckle protruding forward at the bottom. The open circular buckle has a slot at the top and bottom, and the same elastic buckle is engaged in the two slots. Each side upright has a support component at the bottom.

[0008] The crossbeam has protrusions at both ends, and the side panels have insertion slots that correspond one-to-one with the protrusions of the crossbeam. The inner upper end of the protrusions on both sides of the topmost crossbeam abuts against the outside of the side panel, and the outer lower end of the protrusions abuts against the inside of the side panel. The side panels and the crossbeam cannot move and are firmly fixed. The protrusions at both ends of the two middle crossbeams can be inserted into the insertion slots of the side panels and then pushed downwards to fix the side panels in place.

[0009] The support assembly includes two identical support plates I hinged to the bottom of the side stand. The two support plates I are respectively hinged to the two sides of the side stand. A semi-circular notch is opened on the front side of the bottom of the support plate I. The support plate I is used to hold the motorcycle tail frame upright and install the backrest on the bracket composed of the side stand and the crossbeam. The lower end of the side stand is fastened to the crossbar of the motorcycle tail frame.

[0010] The fixing groove on the bottom crossbeam is connected to a fixing Velcro, which is used to fix it to the motorcycle tail rack.

[0011] The support assembly includes support plates II hinged to both sides of the bottom of the side stand. The bottom of the side stand has an arc-shaped groove, and the top of the support plate II is slidably connected in the arc-shaped groove. The rotation center of the support plate II is at the bottom of the side stand. As the support plate II rotates, the top of the support plate II rotates at a certain angle within the arc. When the backrest is upright or unfolded, the rotation angle of the support plate II is exactly resisted by the limit of the front end of the arc-shaped groove, so that it can support the backrest. When folded, the support plate II rotates in the opposite direction and moves towards the direction of the open circular buckle.

[0012] The card slots are provided in several places, and the position of the card slots can be adjusted according to the elastic buckle.

[0013] The support assembly includes support plate III, which is integral with the side support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention enables quick assembly and disassembly of the backrest bracket via an elastic buckle. Furthermore, most motorcycles have a tail rack crossbar to assist the driver in carrying or moving the motorcycle, thus meeting the needs of installing backrests on various motorcycle models.

[0025] Example 1

[0026] like Figures 1-5 As shown, the multi-functional motorcycle backrest bracket 9 of this utility model includes two side panels 4, with several crossbeams 6 connected between the two side panels 4. The crossbeams 6 have several connecting holes 8 and fixing grooves 7. Each side panel 4 has a forward-protruding open circular buckle 3 at its bottom. The open circular buckle 3 has slots 2 at its upper and lower parts, and the same elastic buckle 13 is engaged in both slots 2. Each side panel 4 has a support assembly at its bottom. The crossbeams 6 have protrusions at both ends, and the side panels 4 have insertion slots 5 corresponding to the protrusions of the crossbeams 6. The upper inner sides of the protrusions on both sides of the topmost crossbeam 6 press against the outside of the side panel 4, and the lower outer sides of the protrusions press against the inside of the side panel 4. The side panels 4 and the crossbeams 6 cannot move. The two crossbeams 6 in the middle are fixed firmly. The protruding parts at both ends can be inserted into the insertion slots 5 of the side uprights 4, and then pushed downwards to fix the side uprights 4 in place. The support assembly includes two identical support pieces I1 hinged to the bottom of the side uprights 4. The two support pieces I1 are respectively hinged to the two sides of the side uprights 4. The bottom front side of the support piece I1 has a semi-circular notch. The support piece I1 is used to support the motorcycle tail frame 11 to keep the backrest 9 upright. The backrest 9 is installed on the bracket composed of the side uprights 4 and the crossbeams 6. The lower end of the side uprights 4 is fastened to the crossbar 10 of the motorcycle tail frame 11. The fixing slot 7 on the lowest crossbeam 6 is connected to a fixing hook 12, which is used to fix it to the motorcycle tail frame 11.

[0027] Working process or working principle:

[0028] In use, first assemble the side support plate 4, crossbeam 6, and support components. Then, fix the backrest 9 to the connecting hole 8 and fixing groove 7 of the crossbeam 6 with bolts to connect the backrest 9 to the bracket. At this time, fasten the open circular buckle 3 to the crossbar 10 of the motorcycle tail rack 11. Then, wrap the elastic buckle 13 around the crossbar 10 and insert its two ends into the slot 2 to fix the bracket to the crossbar 10. Then, adjust the tilt angle of the support plate I1 to support it on the tail rack 11 and fix it by passing the fixing magic buckle 12 through the fixing groove 7 of the bottom crossbeam 6 and the tail rack 11. When it needs to be flat, remove the fixing magic buckle 12. Then rotate the support plate I1 forward. The semi-circular notch of the support plate I1 can correspond to the crossbar 10. The support plate I1 also has a slot 2. Before flattening, remove the lower end of the elastic buckle 13 so that the support plate I1 passes through the elastic buckle 13 and is locked in the slot 2 of the support plate I1 to fix and store the support plate I1.

[0029] Example 2

[0030] like Figure 6 As shown, unlike Embodiment 1, the support assembly in this embodiment includes support plates II14 hinged to both sides of the bottom of the side stand 4. The bottom of the side stand 4 is provided with an arc-shaped groove 15. The top of the support plate II14 is slidably connected in the arc-shaped groove 15. The rotation center of the support plate II14 is at the bottom of the side stand 4. As the support plate II14 rotates, the top of the support plate II14 rotates at a certain angle within the arc. When the backrest 9 is upright and unfolded, the rotation angle of the support plate II14 is exactly resisted by the front end limit of the arc-shaped groove 15, so that it can support the backrest 9. When folded, the support plate II14 rotates in the opposite direction and moves towards the open circular buckle 3. The buckle 2 is provided with several slots, and the position of the buckle 2 can be adjusted according to the elastic buckle 13.

[0031] Example 3

[0032] like Figures 7-8 As shown, unlike other embodiments, the support component described in this embodiment includes a support plate III16. The support plate III16 and the side upright plate 4 are integrated. When upright, it is tightened by the fixed magic buckle 12 to prevent it from tilting forward. When it needs to be flattened, the fixed magic buckle 12 is removed, the open circular buckle 3 is separated from the crossbar 10, and then the open circular buckle 3 is fastened to the crossbar 10 to achieve the backrest being laid flat. At this time, the movement is restricted between the integrated support plate III and the tail frame 11, so that it will not rotate and stand up.

[0033] This utility model enables quick assembly and disassembly of the backrest 9 bracket via the elastic buckle 13. Furthermore, most motorcycles have a tail rack 11 crossbar 10 on the tail rack 11 to help the driver carry or move the motorcycle, thus meeting the needs of installing the backrest 9 on various motorcycle models.

[0034] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
