The direction of the buckle is single, and both are along the axis direction of the handlebar cross tube of the electric assist bicycle;

[0005] 2. When the single split buckle fixed by the card slot fixing method and the electric bicycle instrument need to be adjusted in the up and down directions along the vertical plane of the axis of the handlebar cross tube of the electric assist bicycle, it is necessary to manually loosen the fixing screw between the single split buckle and the handlebar cross tube first. After adjusting the angle of the instrument in place, then tighten the fixing screw. The adjustment operation process is very cumbersome and inconvenient;

[0006] 3. This adjustment process must be completed by both hands in coordination when the electric assist bicycle is in a stationary state; and when the electric assist bicycle is in a riding state, it is impossible to manually adjust the angle of the electric assist bicycle instrument.

[0021] The following further clarifies the present invention in conjunction with the accompanying drawings and specific embodiments. These embodiments are implemented on 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 not to limit the scope of the present invention.

[0022] As Figures 1 to 4 shown, the embodiment of the present invention provides an installation structure for an angle-adjustable electric assist bicycle instrument, including a connection seat 2 hinged to the lower side of the instrument lower cover 1 and a buckle 3 fixedly connected to the connection seat 2. A limiting structure is provided between the lower side of the instrument lower cover 1 and the connection seat 2. The above-mentioned buckle 3 includes a main body 5 for fixing on the outer side of the handlebar cross tube 4 of the electric assist bicycle and a connection part 6 provided at the upper end of the main body 5. Specifically, the main body 5 is fixed on the handlebar cross tube 4 through the cooperation of a locking bolt 7 and a locking nut. The connection seat 2 is fixedly connected to the upper side of the connection part 6 through two fixing bolts 9.

[0023] Preferably, two connection ears 10 are provided at intervals and oppositely on the lower side of the instrument lower cover 1. A connection block 11 is provided in the middle of the upper side of the connection seat 2. The connection block 11 is arranged between the two connection ears 10. The connection block 11 and the two connection ears 10 are correspondingly provided with through holes. An elastic tightening bolt 12 is inserted into the through holes, and the elastic tightening bolt 12 is threadedly connected to an elastic tightening nut 13. The width of the connection block 11 is slightly smaller than the distance between the two connection ears 10. In the natural state, when the connection block 11 is placed between the two connection ears 10, a gap will be formed between the connection block 11 and the inner sides of the connection ears 10. When the elastic tightening bolt 12 and the elastic tightening nut 13 are properly tightened, the two connection ears 10 will produce slight deformation, and then a certain clamping force will act on both sides of the connection block 11, and under the action of the limiting structure, the instrument can be kept in a predetermined position and can be adjusted in angle by hand.

[0024] Preferably, the lower end of the connection ear 10 of the embodiment of the present invention is provided in an arc shape, the through hole on the connection ear 10 is preferably provided as a round hole, and the center of the circle at the lower end of the connection ear 10 is concentric with the through hole on the connection ear 10. The connection seat 2 includes a seat plate 14. Convex blocks 15 are respectively provided on the upper sides of the seat plate 14 at both ends of the connection block 11. Avoidance holes 8 for the fixing bolts 9 to pass through are provided on both sides of the convex blocks 15 and the seat plate 14. An arc groove for cooperating with the lower end of the connection ear 10 is provided on the upper side of the convex block 15. The above-mentioned limiting structure includes a first toothed ring 16 provided at the lower end of the connection ear 10 and a second toothed ring 17 provided on the upper side of the arc groove. The first toothed ring 16 and the second toothed ring 17 cooperate to achieve a certain limiting effect.

[0025] Preferably, the through hole 18 on the connecting block 11 is arranged as a strip-shaped hole along the vertical direction. After loosening the tension adjusting bolt 12, the matching position between the connecting block 11 and the connecting ear 10 can be adjusted within a certain range, thereby adjusting the meshing depth between the first gear ring 16 and the second gear ring 17, and thus adjusting the limiting force of the cooperation between the first gear ring 16 and the second gear ring 17 after the tension adjusting bolt 12 is fixed. The convex block 15 and the connecting block 11 are preferably integrally formed and are fixed to the upper side of the connecting portion 6 together with the seat plate 14 through the two fixing bolts 9.

[0026] In order to improve the connection reliability between the connecting portion 6 and the connecting seat 2, sliding grooves 19 are provided on both sides of the upper end of the connecting portion 6, and both sides of the seat plate 14 are slidably connected in the sliding grooves 19. After the seat plate 14 is pushed into the sliding groove 19 from one side, the two fixing bolts 9 are fixed, and the sliding groove 19 can play an auxiliary limiting role.

[0027] One end of the connecting portion 6 of the embodiment of the present invention preferably protrudes from one side of the body 5. From the side view, the connecting portion 6 and the body 5 form an inverted L-shaped structure, which can ensure that the connecting portion 6 has a longer dimension, so as to facilitate the mating connection with the connecting seat 2.

[0028] Combined Figures 1 to 4 , based on the above embodiments, those skilled in the art can easily understand that the present invention also provides an angle-adjustable electric assist bicycle meter, which includes the above installation structure.

[0029] During installation, first push the seat plate 14 of the connecting seat 2 into the sliding groove 19 on the buckle 3 from one side, then respectively pass the two fixing bolts 9 through the avoidance holes 8 on the convex block 15 and the seat plate 14, and screw them into the threaded holes provided on the connecting portion 6. Then insert the connecting block 11 of the connecting seat 2 between the two connecting ears 10, and pass the tension adjusting bolt 12 through the two connecting ears 10 and the connecting block 11, and connect it with the tension adjusting nut 13. After adjusting the up and down positions of the connecting seat 2 and the connecting ear 10, tighten the tension adjusting bolt 12 and the tension adjusting nut 13 to the appropriate strength. Finally, fix the buckle 3 on the handlebar cross tube 4 through the cooperation of the locking bolt 7 and the locking nut.

[0030] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, the other parts not specifically described belong to the prior art or common general knowledge. Without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
