Description

Technical Field

[0001] This utility model relates to the field of brake cable clamping technology, specifically to a brake cable calibration clamp for electric bicycles. Background Technology

[0002] Electric bicycles are vehicles that use batteries as auxiliary power and are based on ordinary bicycles, equipped with motors, controllers, batteries, throttles, brake levers, and display systems. With the development of life, social progress, and the popularization of low-carbon and environmentally friendly concepts, more and more people are using electric bicycles for transportation. Most existing electric bicycles still use the same cable-operated brakes as regular bicycles. However, common cable-operated brakes simply use a set of clamps to hold and fix the brake cable. When an electric bicycle brakes frequently or with excessive braking force, the brake cable and the clamps are prone to slippage, resulting in poor clamping effect. This reduces the sensitivity and braking effect of the cable-operated brake, requiring users to recalibrate the clamps. For users who do not know how to calibrate or forget to calibrate, riding directly on the road can easily create corresponding safety hazards. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a brake cable calibration fixture for electric bicycles, including: a calibration component 3; a movable component 2 movably connected to the surface of the brake body 1; the end face of the movable component 2 fixedly connected to the calibration component 3; and a brake cable body 4 fixedly connected inside the calibration component 3. The calibration component 3 consists of a calibration box 10, a rotating column 8, a limiting plate 9, and a fastening plate 12. A guide part 5 is fixedly connected to the outer side of the calibration box 10, and a guide groove is formed inside the guide part 5. Symmetrical through holes are formed on both sides of the inner cavity of the calibration box 10. Both ends of the column 8 are movably connected in the through hole. The end of the rotating column 8 away from the moving part 2 is fixedly connected to the calibration plate 7. The two ends of the rotating column 8 are symmetrically connected to the limiting plate 9. At the same time, the two ends of the calibration box 10 are movably connected to the screw 15 through the clamping sleeve 14. The part of the tail of the screw 15 located inside the calibration box 10 is screwed to the fastening plate 12. The fastening plate 12 is connected to the fastening layer 11 relative to the position of the limiting plate 9. A positioning hole is opened in the middle of the rotating column 8. The brake line body 4 passes through the guide groove, the positioning hole and the through hole opened in the calibration box 10 in sequence.

[0019] In this embodiment, the free end of the brake cable body 4 connected to the brake body 1 is first passed through the guide groove of the guide part 5, the positioning hole of the rotating column 8, and the through hole of the calibration box 10 in sequence. Then, the calibration plate 7 is rotated, and the calibration plate 7 drives the fixedly connected rotating column 8 to rotate synchronously. The rotating column 8 can wind the free end of the brake cable body 4 into a circle through the positioning hole. At this time, the screw 15 is rotated with the help of a tool. The screw 15 will push the screwed fastening plate 12 to move. The fastening plate 12 can abut against the arc surface of the limiting plate 9 through the fastening layer 11. At the same time, the anti-slip plate 6 set on the arc surface of the limiting plate 9 will also squeeze the fastening layer 11 synchronously, thereby completing the fixed connection between the calibration box 10 and the limiting plate 9, enhancing the stability of the connection between the brake cable body 4 and the calibration component 3, and reducing the frequency of the user calibrating the brake cable body 4. When the user rides the electric bicycle and holds the handbrake, the handbrake will pull the moving part 2 and the calibration component 3 of the brake body 1 through the brake cable body 4, thereby braking the electric bicycle.

The outer side of the calibration plate 7 is provided with anti-slip stripes to reduce the chance of slipping.

[0024] As a preferred embodiment, the two groups of limiting plates 9 fixedly connected to both ends of the rotating column 8 are both in an annular structure, and the surfaces of the two groups of limiting plates 9 respectively fit the corresponding surfaces in the inner cavity of the calibration box 10. At the same time, the limiting plate 9 and the rotating column 8 together form a structure with a cross-sectional shape of "卄".

[0025] In this embodiment, as Figure 2 and Figure 4 , the setting of the limiting plate 9 can not only assist in enhancing the stability of the rotating column 8 when rotating in the calibration box 10, but also assist in restricting the winding range of the brake wire main body 4 on the surface of the rotating column 8.

[0026] As a preferred embodiment, a plurality of anti-slip plates 6 are fixedly connected to the outer arc surface of the limiting plate 9 at equal intervals along the circumferential direction. The plurality of anti-slip plates 6 are all in a semi-cylindrical structure. At the same time, the axial length of the anti-slip plate 6 is equal to the axial length of the limiting plate 9.

[0027] In this embodiment, as Figure 2 and Figure 3 , the setting of the anti-slip plate 6 can assist in enhancing the stability of the mutual abutment between the limiting plate 9 and the fastening plate 12, reduce the probability of the brake wire main body 出现松动的几率, and the structural setting of the anti-slip plate 6 can assist in reducing the probability of the fastening layer 11 being damaged due to extrusion. <时防滑板6的结构设置,能够辅助降低紧固层11因挤压而出现破损的几率。<时防滑板6的结构设置,能够辅助降低紧固层11因挤压而出现破损的几率。

[0028] As a preferred embodiment, the two groups of beam position sleeves 14 fixedly connected to the outer side surface of the calibration box 10 are both in a cylindrical structure. The cross-sectional shape of the beam position sleeve 14 is in an L shape. The inner cavity of the beam position sleeve 14 and the end face size of the screw 15 are adapted.

Also, the repeated and incorrect "出现松动的几率" in the translation of should be corrected according to the correct meaning. The above translation is for reference only.The fastening layer 11 is made of soft rubber, which helps to enhance the contact and fixing effect of the fastening plate 12 on the limiting plate 9.
