Description

Technical Field

[0001] This utility model relates to the field of electric-assisted bicycle instrument technology, specifically to an electric-assisted bicycle instrument mounting structure with freely adjustable angle. Background Technology

[0002] The mounting structures for quick-assembly e-bike gauges fall into two categories: fixed snap-fit ​​mounting structures and separate snap-fit ​​mounting structures. These are primarily used for securing the e-bike gauges and handlebars. Fixed snap-fit ​​mounting structures are integrated with the gauges and cannot be replaced. Separate snap-fit ​​mounting structures connect to the gauges via mounting holes and are replaceable. Both fixed and separate snap-fit ​​mounting structures are essential components of e-bike gauges.

[0003] Deficiencies of existing technology:

[0004] 1) Electric bicycles with a split-type buckle mounting structure can only rotate in the direction perpendicular to the axis of the electric bicycle's cross tube. In other directions, the electric bicycle's instrument panel cannot be freely adjusted.

[0005] 2) When the instrument panel of an electric bicycle, which is fixed to the split-type buckle mounting structure through the mounting hole, needs to be adjusted in the direction of the vertical plane of the handlebar axis, the fixing screw in the mounting hole must be loosened manually first, the instrument angle is adjusted to the correct position, and then the fixing screw in the mounting hole is tightened. The adjustment operation is cumbersome and inconvenient.

[0006] 3) This adjustment process must be completed with both hands in coordination while the electric-assist bicycle is stationary; it is not possible to freely adjust the angle of the electric-assist bicycle instrument with one hand while riding the electric-assist bicycle. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a freely adjustable instrument mounting structure for electric-assisted bicycles.

[0008] To achieve the above objectives, this utility model provides an adjustable-angle instrument mounting structure for electric-assisted bicycles, including an instrument body, a fixing component, and a movable connecting mechanism connecting the instrument body and the fixing component.

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0022] like Figures 1 to 4 As shown, this utility model embodiment provides an adjustable-angle instrument mounting structure for an electric-assist bicycle, including an instrument body 1, a fixing member 2, and a movable connecting mechanism 3 connecting the instrument body 1 and the fixing member 2. The fixing member 2 is used to fix the instrument to the handlebar cross tube 4. The movable connecting mechanism 3 includes an adjusting rod 31 fixedly disposed in the lower middle part of the instrument body 1. The lower end of the adjusting rod 31 has a spherical structure 32, which protrudes from the lower side of the instrument body 1. A connecting seat 33 is fixedly connected to the upper side of the fixing member 2. The upper middle part of the connecting seat 33 has a groove 34. The interior of the groove 34 is an arc-shaped structure, and its inner diameter is adapted to the spherical structure 32, so that the lower outer side of the spherical structure 32 is slidably connected to the groove 34. A base nut 35 is threadedly connected to the outer side of the connecting seat 33. The middle outer diameter of the adjusting rod 31 is smaller than the inner diameter of the upper end of the groove 34, so that the adjusting rod 31 can rotate back and forth and left and right within a certain range relative to the groove 34. The base nut 35 serves two purposes: firstly, it keeps the spherical structure 32 within the groove 34, preventing it from dislodging; secondly, it increases the damping between the connecting seat 33 and the spherical structure 32, ensuring that the instrument body 1 remains at a predetermined angle under normal conditions, and that the angle of the instrument body 1 can be adjusted with one hand. To facilitate the insertion of the spherical structure 32 into the groove 34 and to increase the damping between the connecting seat 33 and the spherical structure 32, it is preferable to have several vertical openings 38 at the upper end of the connecting seat 33. This allows the upper end of the connecting seat 33 to deform outwards and open when the spherical structure 32 is inserted, and to tighten inwards when the base nut 35 is tightened.

[0023] The instrument body 1 of this embodiment includes an upper instrument cover 11 and a lower instrument cover 12. The upper instrument cover 11 and the lower instrument cover 12 are fixedly connected, and the adjusting rod 31 is fixedly connected to the lower center of the lower instrument cover 12. Specifically, a connecting groove 36 is formed by an upward protrusion in the lower center of the lower instrument cover 12. The connecting groove 36 has an internal thread structure, and the upper end of the adjusting rod 31 has an external thread structure that mates with the internal thread structure, so that the adjusting rod 31 is threadedly connected to the connecting groove 36. A positioning nut 37 is threadedly connected to the outer side of the adjusting rod 31. The positioning nut 37 can be used to adjust the length of the adjusting rod 31 extending into the connecting groove 36 and to lock the adjusting rod 31 and the lower instrument cover 12 together. In addition, to improve the connection strength, a nut 39 can also be fixedly embedded in the connecting groove 36 and threadedly connected to the upper end of the adjusting rod 31. The embedded nut 39 can be fixed in the lower instrument cover 12 during injection molding.

[0024] The fastener 2 in this embodiment of the invention includes an upper buckle 21 and a lower buckle 22. One end of the upper buckle 21 and the lower buckle 22 are hinged together by a pin 29, and the other end of the upper buckle 21 and the lower buckle 22 are detachably and fixedly connected, preferably by bolts 23 and nuts 24. To improve the fixing strength with the handlebar cross tube 4, multiple anti-slip grooves 28 can be provided on the inner side of both the upper buckle 21 and the lower buckle 22.

[0025] A slot 25 is provided on the upper side of the upper buckle 21. The lower end of the connecting seat 33 is inserted into the slot 25. A connecting hole 26 is provided at the bottom of the groove 34. A screw 27 is inserted into the connecting hole 26. The screw 27 is threadedly connected to the upper buckle 21, thereby fixing the connecting seat 33 to the upper buckle 21. It should be noted that the connecting hole 26 is a countersunk hole, which prevents the upper end of the screw 27 from contacting the spherical structure 32, thereby avoiding affecting the rotation of the spherical structure 32 in the groove 34.

[0026] The specific installation process of this utility model is as follows:

[0027] 1) Close the upper cover 11 and the lower cover 12 of the instrument together and glue them together.

[0028] 2) Screw the upper end of the adjusting rod 31 into the embedded nut 39 on the lower cover 12 of the instrument, and then lock the adjusting rod 31 with the positioning nut 37.

[0029] 3) Secure the connecting seat 33 and the upper buckle 21 together with screws 27, and then hinge the upper buckle 21 and the lower buckle 22 together with pins 29.

[0030] 4) Insert the spherical structure at the lower end of the adjusting rod 31 into the groove 34, and then screw the base nut 35 onto the connecting seat 33.

[0031] 5) Use bolts 23 and nuts 24 to lock and fix the upper buckle 21, lower buckle 22 and handlebar cross tube 4 into one piece.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that for those skilled in the art, other parts not specifically described are existing technology or common knowledge. Several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
