[0025] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0026] Below in conjunction with Figures 1-5 Describe the rear tail frame according to an embodiment of the present utility model.

[0027] The rear tail frame of the embodiment of the present utility model includes a base and a seat cushion 4. The base includes a left decorative plate 1, a right decorative plate 2 and a bottom plate 3. The left decorative plate 1 and the right decorative plate 2 are arranged along the first direction and are each adapted to be detachably connected to the rear of the vehicle body. The bottom plate 3 is detachably connected to each of the left decorative plate 1 and the right decorative plate 2. The seat cushion 4 is detachably connected to the bottom plate 3.

[0028] For the rear tail frame according to an embodiment of the present utility model, the base is installed on the rear of the vehicle body through the left decorative plate 1 and the right decorative plate 2. The bottom plate 3 of the base is detachably connected to the left decorative plate 1 and the right decorative plate 2, and the seat cushion 4 is detachably connected to the base. At this time, the bottom plate 3 and the seat cushion 4 can be retained, and only the left decorative plate 1 and the right decorative plate 2 of another size are replaced, then the modification of the rear tail frame can be completed. Thus, not only the disassembly and assembly procedures of some parts are reduced, making the modification of the rear tail frame convenient, but also the original bottom plate 3 and seat cushion 4 are utilized, reducing the modification cost of the rear tail frame.

[0029] It should be noted that the first direction is the width direction of the two-wheeled vehicle, that is, the left-right direction of the two-wheeled vehicle. In addition, in this embodiment, it is also possible to only replace the size of one of the bottom plate 3 and the seat cushion 4, retain the other of the bottom plate 3 and the seat cushion 4, and retain the left decorative plate 1 and the right decorative plate 2, which also has the advantages of convenient modification and low modification cost.

[0030] In some embodiments, such as Figure 4 andFigure 5 As shown, both the left decorative panel 1 and the right decorative panel 2 include a side plate 11 and a connecting plate 12. The connecting plate 12 is connected to the upper end of the side plate 11. The connecting plate 12 is located on the side of the side plate 11 facing the other side plate 11. The bottom plate 3 is detachably connected to the two connecting plates 12.

[0031] The two side plates 11 are respectively arranged on the left and right sides of the bottom plate 3 and the seat cushion 4 to ensure the aesthetic appearance of the rear tail frame. The design of the connecting plate 12 being arranged inside the side plate 11 also facilitates the connection of the bottom plate 3 with the left decorative panel 1 and the right decorative panel 2.

[0032] Specifically, the extending direction of the connecting plate 12 forms an angle with the extending direction of the side plate 11 and is generally perpendicular to each other, thereby effectively improving the structural strength of the left decorative panel 1 and the right decorative panel 2, and the supporting strength of the two for the bottom plate 3 and the seat cushion 4 thereon is higher.

[0033] In some embodiments, as Figure 4 shown, the bottom plate 3 abuts against the upper sides of the two connecting plates 12. The bottom plate 3 is provided with a first mounting hole 31, and the connecting plate 12 is provided with a second mounting hole 121 corresponding to the first mounting hole 31. The bottom plate 3 is connected to the connecting plate 12 through a fastener passing through the first mounting hole 31 and the second mounting hole 121.

[0034] That is, the bottom plate 3 is detachably connected to the two connecting plates 12 through fasteners. Furthermore, the disassembly and assembly between the bottom plate 3 and the connecting plate 12 are convenient, and the connection strength between the bottom plate 3 and the connecting plate 12 is high.

[0035] Specifically, the bottom surface of the bottom plate 3 is in close contact with the top surface of the connecting plate 12. Each connecting plate 12 is provided with at least two second mounting holes 121. That is, the bottom plate 3 is connected to the two connecting plates 12 through at least four fasteners.

[0036] In some embodiments, as Figure 5 shown, there are at least two first mounting holes 31 and they are arranged at intervals along a second direction. The second direction forms an angle with the first direction. At least one first mounting hole 31 is a strip-shaped hole extending along the second direction.

[0037] Thereby, it can better ensure the alignment of the first mounting hole 31 and the second mounting hole 121 to facilitate the connection of the bottom plate 3 and the connecting plate 12. At the same time, this setting also has a low requirement for the processing accuracy of the first mounting hole 31 on the bottom plate 3, thereby further reducing the processing cost of the bottom plate 3.

[0038] Specifically, two first mounting holes 31 are provided at both ends of the bottom plate 3 in the first direction. One of the first mounting holes 31 is a round hole, and the other first mounting hole 31 is a strip-shaped hole. Each connecting plate 12 is correspondingly provided with two second mounting holes 121, and the second mounting holes 121 are all round holes.

[0039] In some embodiments, as Figure 4 shown, the fastener includes a first threaded member 8 and a first welded nut. The first welded nut is welded to the side of the connecting plate 12 facing away from the bottom plate 3. The first threaded member 8 passes through the first mounting hole 31 and the second mounting hole 121 and is in threaded engagement with the first welded nut.

[0040] That is, the first welded nut is pre-welded to the bottom side of the connecting plate 12. After the bottom plate 3 is connected to the connecting plate 12 by the threaded engagement of the first threaded member 8 and the first welded nut, the loosening probability of the first threaded member 8 relative to the first welded nut is lower, and the risk of the first welded nut falling off is lower. Furthermore, the connection reliability between the bottom plate 3 and the connecting plate 12 is higher.

[0041] Specifically, the first threaded member 8 is a bolt. The first welded nuts correspond to the second mounting holes 121 one by one, and the threaded holes on the first welded nuts are coaxial with the corresponding second mounting holes 121.

[0042] In some embodiments, as Figures 1-3 shown, the rear part of the vehicle body includes a rear frame and a rear shock absorber. The connecting plate 12 is provided with a third mounting hole 122 for connecting with the rear frame, and the side plate 11 is provided with a fourth mounting hole 111 for connecting with the rear shock absorber.

[0043] That is, both the left trim panel 1 and the right trim panel 2 are connected to the rear frame and the rear shock absorber of the rear part of the vehicle body through the connecting plate 12 and the side plate 11 respectively. The rear frame and the rear shock absorber jointly support the rear tail frame, and the riding safety of the user on the rear tail frame is higher.

[0044] Specifically, as Figure 5 shown, the third mounting hole 122 is provided at the front end of the connecting plate 12, that is, at one end of the connecting plate 12 adjacent to the rear frame. The connecting plate 12 is connected to the rear frame through a fastener passing through the third mounting hole 122. The fourth mounting hole 111 is provided at the front end of the connecting plate 12 and adjacent to the lower edge. The side plate 11 is connected to the rear shock absorber through a fastener passing through the fourth mounting hole 111.

[0045] In some embodiments, as Figure 2 shown, the rear tail frame further includes a rear armrest 5, and the rear armrest 5 is detachably connected to the bottom plate 3.

[0046] The rear armrest 5 can be held by a user sitting on the seat cushion 4 to improve the riding safety of the user. At the same time, by setting the rear armrest 5 to be connected to the bottom plate 3, when it is necessary to change the size of the rear tail frame, only the sizes of the left trim panel 1 and the right trim panel 2 can be changed, and the rear armrest 5 and the bottom plate 3 can be retained, so as to effectively reduce the modification cost and difficulty of the rear tail frame.

[0047] Meanwhile, the detachable connection between the rear armrest 5 and the bottom plate 3 enables the rear tail rack to have a first state without the rear armrest 5 installed and a second state with the rear armrest 5 installed, without changing the dimensions of the left decorative panel 1 and the right decorative panel 2, thus effectively meeting the user's styling requirements for the rear tail rack.

[0048] Specifically, the rear armrest 5 is connected to the bottom plate 3 by four bolts, and the four bolts are arranged at the four corners.

[0049] In some embodiments, as Figure 3 shown, the rear tail rack further includes an adapter 6 and a rear luggage rack 7. The two ends of the adapter 6 in the first direction are respectively detachably connected to the two side plates 11, and the rear luggage rack 7 is detachably connected to each of the adapter 6 and the bottom plate 3.

[0050] At this time, the rear tail rack further has a third state without the rear armrest 5 installed and with the adapter 6 and the rear luggage rack 7 installed, further meeting the user's styling requirements for the rear tail rack and enabling the two-wheeled vehicle to have better storage function. In addition, the bottom plate 3 and the adapter 6 jointly support the rear luggage rack 7, so that the rear luggage rack 7 has a stronger bearing capacity, and the trunk installed on the rear luggage rack 7 can store heavier items.

[0051] Specifically, the rear end of the bottom plate 3 is connected to the rear luggage rack 7 by bolts. The adapter 6 is connected to the rear ends of the two side plates 11. The central position of the adapter 6 in the first direction is located behind the side plates 11 and is connected to the rear luggage rack 7 by bolts. Thus, the main part of the rear luggage rack 7 is arranged at intervals behind the seat cushion 4, facilitating the installation of the trunk and not interfering with the space above the seat cushion 4, and thus not affecting the riding function of the rear tail rack.

[0052] In some embodiments, as Figure 3 and Figure 4 shown, the adapter 6 is located between the two side plates 11 in the first direction. The side plates 11 are provided with fifth mounting holes 112, and the adapter 6 is provided with sixth mounting holes 61. The rear tail rack further includes a second threaded member 9 and a second welded nut 10. The second welded nut 10 is welded to the adapter 6. The second threaded member 9 passes through the fifth mounting hole 112 and the sixth mounting hole 61 and is in threaded cooperation with the second welded nut 10.

[0053] At this time, the head of the second threaded member 9 is located outside the side plate 11, rather than the rod portion of the second threaded member 9 being exposed outside the side plate 11, effectively avoiding the probability of the rod portion of the second threaded member 9 scratching the user, and the riding safety of the user on the rear tail rack is higher. Moreover, by welding the second welded nut 10 to the adapter 6, the probability of relative rotation and loosening between the second threaded member 9 and the second welded nut 10 is further reduced, and the connection reliability between the adapter 6 and the side plate 11 is higher.

[0054] Specifically, two fifth mounting holes 112 are provided on each side plate 11, that is, each side plate 11 is connected to the adapter 6 through two second threaded members 9, thereby effectively ensuring the relative fixation between the adapter 6 and the side plate 11.

[0055] It should be noted that the seat cushion 4 is snap-connected to the bottom plate 3. At the same time, three seventh mounting holes 32 arranged in a triangle are provided on the bottom plate 3, and three threaded holes are correspondingly provided on the seat cushion 4. The seat cushion 4 is connected to the bottom plate 3 through bolts passing through the seventh mounting holes 32 and threadedly engaged with the threaded holes.
