Description

Technical Field

[0001] The utility model relates to a finger-shift turning handle with an electric display. Background Art

[0002] The thumb throttle is an acceleration component that outputs a linear voltage. It is an important component for adjusting the speed of electric bicycles. Currently, the thumb throttle commonly used in electric bicycles is a Hall-type throttle, which is composed of a magnetic steel, a linear Hall element, a reset spring and a shell.

[0003] Due to the current market demand, a single acceleration function can no longer meet the diverse needs of customers. Customers often need to add switches or electronic displays on the shifter handlebars. The existing solution for adding switches or electronic displays is to use a concentrically rotating shifter and set a switch or electronic display on the rotating movable part. The disadvantages of this solution are: 1. Since the switch or electronic display rotates with the shifter, the content displayed on the electronic display cannot be clearly seen when operating (rotating) the shifter, and it is not convenient to operate the switch when rotating; 2. Since the electronic display or switch needs to be electrically connected using a line, the line is constantly stretched and pulled when the shifter is operated (rotated), and it is very easy to break and lose the relevant function.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0025] like Figures 1 to 4 As shown, a finger-shift throttle 10 with electric display of the present application includes: a locking ring and a rotating handle 22. The locking ring is designed to form a structure with a mounting cavity 14 and a locking portion. The locking portion is locked and fixed to the outer periphery of the handlebar cross tube 29 by a locking screw 23, so that the locking ring is locked to the handlebar cross tube 29 by the locking portion. When the locking ring is installed, the locking portion formed by it is located above the mounting cavity 14, and the locking portion forms an installation cavity 13. An electric display switch 24 is installed in the installation cavity 13 for electric display and operation by customers. In this way, the electric display switch 24 is located at the top, which is convenient for users to use.

[0026] The rotating handle 22 is rotatably installed in the installation cavity 14, and a reset torsion spring 25 is provided between the rotating handle 22 and the cavity wall of the installation cavity 14 for resetting the rotating handle 22, that is, one end of the reset spring sleeved in the rotating handle 22 abuts against the cavity wall of the installation cavity 14, and the other end abuts against the abutting position formed by the rotating handle 22, so that the rotating handle 22 can be reset after the rotating handle 22 is released. The side wall of the installation cavity 14 forms a limited position through groove 141 for the handle of the rotating handle 22 to extend so as to be turned by the user, and when the rotating handle 22 is turned, the rotation stroke of the rotating handle 22 can be limited, that is, the movement of the handle of the rotating handle 22 is limited.

[0027] A Hall component 26 and a circuit board 27 are installed in the installation cavity 14. A magnet 28 is installed at a position corresponding to the Hall component 26 on the rotating handle 22 to cooperate with the Hall component 26 to adjust the output voltage to achieve speed regulation. The Hall component 26 and the electric display switch 24 are both electrically connected to the circuit board 27.

[0028] Through the above scheme, the electric display switch 24 is set on the locking part of the locking ring, the rotating handle 22 is set in the installation cavity 14, and then the circuit board 27 is electrically connected with the electric display switch 24 and the Hall component 26 for data processing and transmission, so that the electric display switch 24 and the rotating handle 22 are installed separately, avoiding the situation that the circuit 18 is always stretched and pulled when the rotating handle 22 is rotated, thereby avoiding the situation that the circuit 18 breaks and causes the electric display switch 24 to lose related functions. At the same time, when the rotating handle 22 is rotated, the electric display switch 24 can also be operated synchronously, which is more convenient and safe to use.

[0029] As a specific implementation, the installation cavity 14 is provided with an installation slot 142 and a line main interface 17, the circuit board 27 is fixed in the installation slot 142, and then the Hall component 26 is electrically installed on one side of the circuit board 27, and the electric display switch 24 and the circuit board 27 are both electrically connected to the line main interface 17 through the line 18. In this way, the connection line 18 of the Hall component 26 and the circuit board 27 and the connection line 18 of the electric display switch 24 are separated, and finally connected through the line main interface 17, so that the connection line 18 of the electric display switch 24 is separated from the connection line 18 of the Hall component 26 and the circuit board 27, thereby further ensuring the installation independence of the electric display switch 24. When operating the rotating handle 22, due to the relative independence of the line 18 and the independent installation structure of the rotating handle 22, it is possible to further avoid pulling interference on the internal line 18, and it is safer to use. The inner wall of the installation cavity 14 is provided with a plurality of positioning buckles 19 for fixing the line 18 to ensure the installation stability of the line 18. When installing, the line 18 is sequentially inserted into the positioning buckles 19, and the connection structure is more stable.

[0030] Furthermore, a slot 1422 is formed in the installation slot 142 for inserting the circuit board 27, a channel 1423 is formed above the installation slot 142 for allowing the connecting line 18 of the circuit board 27 to pass through, and a mounting cover 16 is fixed to the slot of the installation slot 142 for closing the slot. Such a structure is quick to install, and the structural installation inside the installation slot 142 is relatively more stable.

[0031] As a specific implementation, a cover 20 is detachably installed on one side of the installation cavity 14 to seal the installation cavity 14, so that it is more convenient to remove the cover 20 for internal maintenance. The cover 20 is fixed with a wiring sleeve 21, and the line main interface 17 is connected to the external electrical device through the assembly line 18 through the wiring sleeve 21, and the outlet structure is reliable.

[0032] As a specific implementation, a guide arc portion 1421 is formed on the outer side of the groove wall of the installation groove 142 facing the Hall component 26, and the magnet 28 installed on the rotating handle 22 is an arc-shaped magnet 28 that matches the guide arc portion 1421. Such a structural design can ensure the stability of the linear voltage output.

[0033] As a specific embodiment, the locking part includes: a first rotating body 11 and a second fixed body 12, the rotating end of the first rotating body 11 is rotatably connected to the connecting end of the second fixed body 12 through an axle pin, and the locking end of the first rotating body 11 is connected to the locking end of the second fixed body 12 through a locking screw 23, which facilitates the installation or disassembly of the locking part, that is, the installation or disassembly of the entire shift handle.

[0034] In the above design, the first rotating body 11 is formed with the above-mentioned installation cavity 13, and the above-mentioned installation cavity 14 is formed below the second fixed body 12. The rotating end of the first rotating body 11 and the connecting end of the second fixed body 12 are jointly formed with a through groove 15 on the inner side of the locking portion for allowing the line 18 to extend from the installation cavity 13 into the installation cavity 14. With this design, when the first rotating body 11 and the second rotating body are rotated, the pulling effect on the line 18 is minimized.

[0035] Furthermore, the second fixed body 12 is provided with a pressing plate 122 at one end of the rotating end facing the first rotating body 11 for guiding and pressing the circuit 18, so as to prevent the circuit 18 from being stuck in the gap between the first rotating body 11 and the second rotating body when the two are rotated.

[0036] As a specific implementation, the handlebar cross tube 29 forms a limiting recess 291, and the inner wall of the locking portion forms a limiting protrusion 121, and the limiting protrusion 121 is inserted into the limiting recess 291 to abut against the upper wall of the limiting recess 291, thereby preventing relative rotation between the locking ring and the handlebar cross tube 29.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
