[0002] An electric bicycle (also known as an electric-assisted bicycle) is a means of transportation that is based on the structure of a pedal bicycle and is equipped with a battery and a hub motor / generator.

[0003] The amount of electricity stored in the battery determines the driving time and distance of the electric bicycle. There are two ways to charge the battery: one is to use a power source to charge the battery; the other is to use the damping inside the hub motor / generator when the electric bicycle is going downhill or braking to generate electricity, and use this electricity to charge the battery.

[0004] However, the existing method of using brakes to generate electrical energy through the damping inside the wheel hub motor / generator cannot accurately generate the preset electrical energy. This is because when the user presses the brake handle, the damping inside the wheel hub motor / generator is the same regardless of whether the distance pressed each time is the same. Therefore, when the vehicle speed and the damping do not match, the preset electrical energy cannot be accurately generated.

[0005] Therefore, using the depth of braking to accurately generate the preset electrical energy has become a project that the industry is eager to improve and innovate. Summary of the invention

[0024] In order to enable technicians in this technical field to fully understand the technical features, contents, advantages and beneficial effects of the present application, the present application is hereby described in detail in conjunction with drawings and in the form of embodiments as follows. The drawings used therein are only for illustration and auxiliary description purposes, and may not be the actual proportions and precise configurations after the implementation of the present application. Therefore, they should not be limited to the scope of rights of the present application in actual implementation, and it is necessary to make it clear in advance.

[0025] Figure 1 This is a schematic diagram of an electric control handlebar assembly of an electric bicycle according to Embodiment 1 of the present application. Figure 2 This is a schematic diagram of the displacement prompt unit of Example 1 of the present application, please refer to Figure 1 and Figure 2 The embodiment of the present application provides an electric control handlebar set of an electric bicycle, and the electric control handlebar set of the electric bicycle includes a calculation unit 10, a brake line 11, a handle 12, a displacement sensing unit 13 and a displacement prompt unit 14.

[0026] The calculation unit 10 is disposed on the frame of the electric bicycle (not shown in the figure). The calculation unit 10 is electrically connected to a control unit 20, and the control unit 20 is electrically connected to a hub motor / generator 211. The calculation unit 10 is a micro-physical system having functional modules such as communication transmission, hardware circuits such as microcontroller and memory, system driving software, and calculation software of battery characteristic degradation indicator parameter algorithm.

[0027] The brake line 11 is arranged at the frame. The handle 12 is arranged at the frame and is adjacent to one end of the brake line 11, or the handle 12 is arranged adjacent to the brake line 11. The handle 12 includes a fulcrum portion 120 and a pressing portion 121.

[0028] In some embodiments of the present application, the displacement sensing unit 13 is disposed at the fulcrum 120 to sense the distance moved or the angle rotated when the pressing portion 121 is pressed. The displacement sensing unit 13 is an encoder or an angle meter. The displacement sensing unit 13 is electrically connected to the calculation unit 10.

[0029] The displacement prompt unit 14 includes a spring piece 140 and a step structure 141. In some embodiments of the present application, the step structure 141 is disposed at the vehicle frame, and the step structure 141 includes a plurality of steps 1410. The spring piece 140 is disposed at the pressing portion 121, and the free end of the spring piece 140 contacts any step 1410 of the step structure 141. In other embodiments of the present application, the step structure 141 is disposed at the pressing portion 121. The spring piece 140 is disposed at the vehicle frame, and the free end of the spring piece 140 contacts any step 1410 of the step structure 141. For example, when the pressing portion 121 is pressed, the pressing portion 121 causes the spring piece 140 to move in conjunction with it, and the free end of the moving spring piece 140 moves along the steps 1410 of the step structure 141 until the pressing portion 121 stops moving, and the spring piece 140 also stops moving and contacts the steps 1410 of the step structure 141.

[0030] When the user wants to slow down the electric bicycle on a downhill slope, the user presses the pressing portion 121 to a first angle or a first distance, and the spring 140 moves from the original first step 1410 to another step 1410 and abuts against the other step 1410. At this time, the user knows that the pressing portion 121 has been pressed down to the first angle or the first distance through the feedback of the spring 140 abutting against the other step 1410. The feedback can be sound, resistance, or a combination of sound and resistance.

[0031] The displacement sensing unit 13 senses that the pressing portion 121 has moved to a first angle or a first distance, and transmits a first displacement message to the calculation unit 10. For example, when the pressing portion 121 is pressed down, the displacement sensing unit 13 located at the fulcrum portion 120 senses the angle of rotation or the distance of movement of the pressing portion 121; or the displacement sensing unit 13 senses the angle of rotation or the distance of movement of the pressing portion 121 mechanically, inductively or optically, thereby sensing that the pressing portion 121 has moved to the first angle or the first distance. The calculation unit 10 calculates the first damping message corresponding to the first displacement message based on the first displacement message, and transmits the first damping message to the control unit 20, which then transmits the first damping message to the hub motor / generator 211. The hub motor / generator 211 generates a first damping inside thereof based on the first damping message, and generates electrical energy corresponding to the first damping.

[0032] Similarly, when the pressing portion 121 moves from the first angle to the Nth angle, or from the first distance to the Nth distance, the displacement prompt unit 14 gives corresponding feedback to remind or inform the user. The displacement sensing unit 13 transmits the first displacement message to the Nth displacement message to the calculation unit 10, and the calculation unit 10 calculates the first damping message to the Nth damping message. The hub motor / generator 211 generates the first damping to the Nth damping in its interior according to the first damping message to the Nth damping message, and generates electrical energy corresponding to the first damping to the Nth damping. Wherein N is a constant. In addition, when the pressing portion 121 moves from the first angle to the Nth angle, or from the first distance to the Nth distance, the brake line linked to the pressing portion 121 will also drive the brake. For example, the first angle to the Nth angle or the first distance to the Nth distance corresponds to shallow braking to deep braking.

[0033] Figure 3 This is a schematic diagram of an electric control handlebar assembly of an electric bicycle according to Embodiment 2 of the present application. Figure 4 This is a schematic diagram of the displacement prompt unit of Example 2 of the present application, please refer to Figure 3 and Figure 4 In an embodiment of the present application, another electric control handlebar set of an electric bicycle is provided. The electric control handlebar set of the electric bicycle includes a calculation unit 30, a brake line 31, a handle 32, a displacement sensing unit 33 and a displacement prompt unit 34.

[0034] The calculation unit 30 is disposed on the frame of the electric bicycle and is electrically connected to a control unit 400 , which is electrically connected to a hub motor / generator 41 .

[0035] The brake line 31 is disposed on the frame. The handle 32 is disposed on the frame and is adjacent to one end of the brake line 31. The handle 32 includes a fulcrum portion 320 and a pressing portion 321.

[0036] In some embodiments of the present application, the displacement sensing unit 33 is disposed on the brake line 31 and adjacent to the handle 32 . The displacement sensing unit 33 is a displacement sensor and is electrically connected to the calculation unit 30 .

[0037] The displacement prompting unit 34 includes a ratchet 340 and a pawl 341. The ratchet 340 includes a plurality of teeth 3400. The ratchet 340 is disposed at the fulcrum portion 320, the pawl 341 is disposed at the pressing portion 321, and the free end of the pawl 341 abuts against a tooth 3400 of the ratchet 340; or the ratchet 340 is disposed at the fulcrum portion 320, the pawl 341 is disposed at the frame, and the free end of the pawl 341 abuts against a tooth 3400 of the ratchet 340.

[0038] When the user presses the pressing portion 321 to the first distance, the pawl 341 moves from the original tooth 3400 to another tooth 3400 and abuts against the other tooth 3400. At this time, the user knows that the pressing portion 121 has been pressed down to the first distance through the feedback of the pawl 341 abutting against the ratchet wheel 340.

[0039] The displacement sensing unit 33 senses the first distance and transmits the first displacement information to the calculation unit 30. The calculation unit 30 calculates the first damping information corresponding to the first displacement information according to the first displacement information, and transmits the first damping information to the control unit 400, and the control unit 400 transmits the first damping information to the hub motor / generator 41. The hub motor / generator 41 generates the first damping inside according to the first damping information, and generates electric energy corresponding to the first damping.

[0040] In summary, the displacement prompt unit 14 of the present application can set the feedback from the first distance to the Nth distance or the first angle to the Nth angle according to the number of steps 1410 or the number of teeth 3400 of the displacement prompt unit 34, so that the user can know that when the pressing part moves to the first angle to the Nth angle, or the first distance to the Nth distance, the hub motor / generator will generate corresponding damping according to the first damping message to the Nth damping message, so that the vehicle speed can be matched with the damping and the preset electrical energy can be accurately generated.
