Detailed implementation manners

[0032] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the handlebar mounting structure of the electric bicycle and the electric bicycle of the present utility model will be further described in detail below with reference to 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.

[0033] Embodiment 1

[0034] As Figure 1As shown in the figure, a handlebar mounting structure for an electric bicycle is used to mount the handlebar 1 on the frame of the electric bicycle (not shown in the figure). The frame has a mounting post 2 extending upward. The handlebar mounting structure of the electric bicycle includes a connecting column 3 and a mounting rod 4. The connecting column 3 is vertically arranged above the mounting post 2, and the bottom end is connected to the top end of the mounting post 2. The two ends of the mounting rod 4 in the extending direction are respectively a connecting end 5 and a mounting end 6. The connecting end 5 is hinged to the top end of the connecting column 3, and the handlebar 1 is fixedly connected to the mounting end 6, so that the mounting rod 4 can drive the handlebar 1 to convert and move between a first position and a second position with a distance. It should be noted that when the mounting rod 4 drives the handlebar 1 to rotate to a suitable position, any implementable technical solution can be adopted to fix the mounting rod 4 and the connecting column 3 together. By adopting such a technical solution, the rotation of the handlebar 1 can be driven by the mounting rod 4 to adjust the distance (which can be the horizontal distance) between the handlebar 1 and the seat of the electric bicycle (not shown in the figure). In this way, the relative position between the handlebar and the seat can be adjusted to suit the height or arm length of the rider. It not only has high working adaptability, but also can ensure the comfort of the rider.

[0035] Specifically, as Figure 1 , 2 shown, it further includes a first hinge shaft 7, an upper end face 8 of the top end of the connecting column 3 extending in the horizontal direction. An articulated protrusion 9 is provided on the upper end face 8, and a first articulated hole 10 is provided on the articulated protrusion 9. A second articulated hole 11 is provided at the connecting end 5. The first hinge shaft 7 passes through the first articulated hole 10 and the second articulated hole 11 to hinge the connecting column 3 and the mounting rod 4 together through the first hinge shaft 7. When the extending direction of the mounting rod 4 is parallel to the upper end face 8, the mounting rod 4 can abut against the upper end face 8. It should be noted that when the extending direction of the mounting rod 4 is parallel to the upper end face 8, the handlebar 1 can be in two positions on both sides of the articulated protrusion 9. That is to say, when the handlebar 1 is in these two positions, the upper end face 8 can block the mounting rod 4 to prevent the mounting rod 4 from driving the handlebar to move downward. During specific production, as Figure 1 , 2 shown, the connecting end 5 has a first articulated ear plate 12, and the second articulated hole 11 is provided on the first articulated ear plate 12. The number of the first articulated ear plates 12 is two, and the two first articulated ear plates 12 are respectively on both sides of the articulated protrusion 9.

[0036] Embodiment 2

[0037] Based on Embodiment 1, as Figure 1 , 3As shown, it further includes a clamping cover plate 13 and a connecting screw 14. The installation end 6 has a first clamping end face 15, on which a connecting screw hole 16 is provided. A connecting through hole 17 is provided on the clamping cover plate 13. The connecting screw 14 passes through the connecting through hole 17 and is threadedly connected to the connecting screw hole 16. The handlebar 1 is located between the first clamping end face 15 and the clamping cover plate 13, so that the clamping cover plate 13 clamps and fixes the handlebar 1 on the first clamping end face 15 under the screwing action of the connecting screw 14. With such a technical solution, the components are convenient for the installation or disassembly between the handlebar 1 and the mounting rod 4, and at the same time, the firmness of the connection between the two can be ensured.

[0038] Furthermore, as Figure 3 shown, the surface of the clamping cover plate 13 facing the first clamping end face 15 is a second clamping end face 18. A first receiving groove 19 with a shape matching that of the handlebar 1 and extending in the horizontal direction is provided on the first clamping end face 15. A second receiving groove 20 with a shape matching that of the handlebar 1 and extending in the horizontal direction is provided on the second clamping end face 18. When the clamping cover plate 13 clamps and fixes the handlebar 1 on the first clamping end face 15, at least part of the handlebar 1 is located within the first receiving groove 19 and the second receiving groove 20. This can ensure the accuracy of the installation position of the handlebar 1 on the first clamping end face 15 and avoid displacement of the handlebar 1 on the first clamping end face 15 during the installation process.

[0039] In actual production, the number of the connecting screw holes 16 is at least two. The at least two connecting screw holes 16 are located on both sides of the first receiving groove 19. The number of the connecting through holes 17 is equal to the number of the connecting screw holes 16 and they correspond one by one. The number of the connecting screws 14 is equal to the number of the connecting screw holes 16 and they correspond one by one. This can further enhance the firmness of the clamping of the handlebar 1.

[0040] Embodiment Three

[0041] Based on Embodiment One or Embodiment Two, as Figure 1As shown in the figure, it further includes a transfer pipe 21 and a positioning screw 22. The bottom end of the transfer pipe 21 is sleeved on the top end of the mounting post 2, and the top end extends upward. A positioning screw hole 23 matching the positioning screw 22 is provided on the side wall of the transfer pipe 21. The positioning screw 22 is threadedly connected in the positioning screw hole 23 and can abut against the side wall of the part of the mounting post 2 within the transfer pipe 21 by screwing into the positioning screw hole 23, so as to fix the transfer pipe 21 and the mounting post 2 together. The bottom end of the connecting upright column 3 is hinged to the top end of the transfer pipe 21, so that the connecting upright column 3 can rotate relative to the mounting post 2 between a third position and a fourth position. The third position is the position when the included angle between the axis of the connecting upright column 3 and the axis of the mounting post 2 is 180º, and the fourth position is the position when the included angle between the axis of the connecting upright column 3 and the axis of the mounting post 2 is less than 180º and greater than or equal to 0º. Adopting such a technical solution can realize the folding between the connecting upright column 3 and the mounting post 2, that is, the handlebar 1 and the vehicle frame can be folded up.

[0042] In actual production, as Figure 1 shown in the figure, the number of the positioning screw holes 23 is at least two. At least two positioning screw holes 23 are arranged at intervals in sequence along the axial direction of the transfer pipe 21, and / or at least two positioning screw holes 23 are arranged uniformly along the circumferential direction of the transfer pipe 21. The number of the positioning screws 22 is equal to the number of the positioning screw holes 23 and they correspond one by one.

[0043] Specifically, as Figure 1 、 4 shown in the figure, it further includes a first connecting plate 24, a second connecting plate 25 and a second hinge shaft 26. The first connecting plate 24 is fixedly connected to the bottom end of the connecting upright column 3, and the extending direction is perpendicular to the extending direction of the connecting upright column 3. The second connecting plate 25 is fixedly connected to the top end of the transfer pipe 21, and the extending direction is perpendicular to the extending direction of the transfer pipe 21. The two ends of the first connecting plate 24 in the extending direction are respectively a first hinge end 27 and a first free end 28. A third hinge hole 29 is provided at the first hinge end 27. The two ends of the second connecting plate 25 in the extending direction are respectively a second hinge end 30 and a second free end 31. A fourth hinge hole 32 is provided at the second hinge end 30. The second hinge shaft 26 passes through the third hinge hole 29 and the fourth hinge hole 32, so that the first connecting plate 24 can drive the connecting upright column 3 to rotate between the third position and the fourth position. When the connecting upright column 3 is in the third position, the end face of the first connecting plate 24 facing away from the connecting upright column 3 is attached to the end face of the second connecting plate 25 facing away from the mounting post 2. When the first connecting plate 24 drives the connecting upright column 3 to rotate from the third position to the fourth position, the end face of the first connecting plate 24 facing away from the connecting upright column 3 is separated from the end face of the second connecting plate 25 facing away from the mounting post 2.

[0044] In actual production, as Figure 4As shown, the first hinge end 27 has a second hinge ear plate 33. The third hinge hole 29 is provided on the second hinge ear plate 33. The number of the second hinge ear plates 33 is two, and the two second hinge ear plates 33 are respectively located on both sides of the second hinge end 30.

[0045] Furthermore, as Figure 1 shown, it further includes a catch 34. The catch 34 is hinged on the second free end 31. When the connecting column 3 is in the third position, the catch can be latched on the first free end 28 to fix the first connecting plate 24 and the second connecting plate 25 together. In this way, the effect of fixing the connecting column 3 and the mounting column 2 together when the connecting column 3 is in the third position is achieved.

[0046] To achieve the object of the invention, the present utility model also provides an electric bicycle, including the handlebar mounting structure of the electric bicycle described in any of the above embodiments.
