DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the following further details the seat mounting structure of the electric bicycle and the electric bicycle of the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] As Figure 1 shown, a seat mounting structure of an electric bicycle is used to mount a seat (not shown in the figure) on the frame (not shown in the figure) of the electric bicycle. The frame has a mounting post 1 extending upward, and further includes: a connecting seat 2, a connecting rod 3 and a fixing member 4. The connecting rod 3 is detachably connected to the top end of the mounting post 1, and its axis coincides with the axis of the mounting post 1. The connecting seat 2 is fixedly connected to the top end of the connecting rod 3, and the upper surface 5 of the connecting seat 2 is a plane extending in the horizontal direction. The seat is arranged on the upper surface 5 and can slide on the upper surface 5. When the seat slides to a preset position on the upper surface 5, it can be fixed on the upper surface 5 through the fixing member 4. During actual installation, the position of the seat on the upper surface 5 can be adjusted first, and after the adjustment is completed, the seat and the connecting seat 2 are fixed together through the fixing member 4. In this way, the position of the seat on the upper surface 5 can be adjusted according to actual needs, that is, the relative distance between the seat and the handlebar in the horizontal direction can be adjusted to suit the height or arm length of the rider, which not only has high working adaptability, but also can ensure the comfort of the rider.

[0030] Specifically, as Figure 2 shown, the fixing member 4 includes a connecting shaft 8, a first clamping member 6 and a second clamping member 7. A waist-shaped hole 9 with a long axis extending in the horizontal direction and a short axis extending in the vertical direction is provided on the connecting seat 2. The two ends of the connecting shaft 8 are respectively a first end 10 and a second end 11. The connecting shaft 8 is inserted through the waist-shaped hole 9, and the first end 10 and the second end 11 respectively extend out from both sides of the waist-shaped hole 9. The first clamping member 6 and the second clamping member 7 are respectively connected to the first end 10 and the second end 11. The bottom of the seat has a mounting protrusion 12, and the seat abuts against the upper surface 5 through the mounting protrusion 12. When the first clamping member 6 and the second clamping member 7 are respectively connected to the first end 10 and the second end 11, the first clamping member 6 and the second clamping member 7 jointly clamp the mounting protrusion 12 to fix the seat on the upper surface 5.

[0031] Furthermore, as Figure 2As shown, the fixing member 4 further includes a first nut 13 and a second nut 14. A first external thread matching the first nut 13 is provided on the first end 10, a second external thread matching the second nut 14 is provided on the second end 11, a first through hole 15 is provided on the first clamping member 6, and a second through hole 16 is provided on the second clamping member 7. The first clamping member 6 is sleeved on the first end 10 through the first through hole 15, the second clamping member 7 is sleeved on the second end 11 through the second through hole 16. The first nut 13 is threadedly connected to the first end 10 and drives the first clamping member 6 to move towards the second clamping member 7 by screwing in on the first end 10. The second nut 14 is threadedly connected to the second end 11 and drives the second clamping member 7 to move towards the first clamping member 6 by screwing in on the second end 11. With such a technical solution, not only can the firmness of the installation between the seat cushion and the connecting seat 2 be ensured, but also the installation and disassembly of the two are facilitated.

[0032] Among them, the connection mode between the connecting seat 2 and the connecting rod 3 can be as Figure 1 shown. An installation groove 17 with a shape matching the top end of the connecting rod 3 is provided on the bottom surface of the connecting seat 2. The top end of the connecting rod 3 extends into the installation groove 17 so that the connecting seat 2 is connected to the top end of the connecting rod 3. This can facilitate the installation or disassembly between the connecting seat 2 and the connecting rod 3. In actual production, when the top end of the connecting rod 3 extends into the installation groove 17, the top end of the connecting rod 3 can be fixed in the installation groove 17 by any achievable method, such as by interference fit.

[0033] As an implementable manner, as Figure 1 shown, it further includes a transition pipe 18. The two ends of the transition pipe 18 are respectively a first connection pipe section 19 and a second connection pipe section 20. The bottom end of the connecting rod 3 is detachably connected to the first connection pipe section 19, and the top end of the mounting post 1 is detachably connected to the second connection pipe section 20 so that the connecting rod 3 is connected to the mounting post 1 through the transition pipe 18. This can facilitate the disassembly or installation between the connecting rod 3 and the mounting post 1.

[0034] Specifically, as Figure 1 、 3As shown, it further includes a first hoop 21. A first notch 22 is provided on the first connecting pipe section 19. The bottom end of the connecting rod 3 extends into the first connecting pipe section 19. The first hoop 21 surrounds the outer wall of the first connecting pipe section 19, and is used to deform the first notch 22 by squeezing the outer wall of the first connecting pipe section 19, thereby fixing the first connecting pipe section 19 and the bottom end of the connecting rod 3 together. The first hoop 21 is not the inventive point of the present invention, but an existing technology. The present invention only utilizes this existing technology and does not intend to improve it. Therefore, the specific structure and working principle thereof will not be described in detail here. In actual production, as Figure 3 shown, the number of the first notches 22 is more than two, and the more than two first notches 22 are arranged at intervals in sequence along the circumferential direction of the first connecting pipe section 19.

[0035] Furthermore, as Figure 1 、 3 shown, it further includes a second hoop 23. A second notch 24 is provided on the second connecting pipe section 20. The top end of the mounting post 1 extends into the second connecting pipe section 20. The second hoop 23 surrounds the outer wall of the second connecting pipe section 20, and is used to deform the second notch 24 by squeezing the outer wall of the second connecting pipe section 20, thereby fixing the second connecting pipe section 20 and the top end of the mounting post 1 together. The second hoop 22 is not the inventive point of the present invention, but an existing technology. The present invention only utilizes this existing technology and does not intend to improve it. Therefore, the specific structure and working principle thereof will not be described in detail here. In actual production, as Figure 3 shown, the number of the second notches 24 is more than two, and the more than two second notches 24 are arranged at intervals in sequence along the circumferential direction of the second connecting pipe section 20.

[0036] To achieve the invention purpose, the present invention also provides an electric bicycle, including the seat mounting structure of the electric bicycle described in any of the above embodiments.

[0037] The above-described embodiments only represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
