Description

Technical Field

[0001] This utility model relates to the field of handlebar structure technology, and in particular to a multi-functional handlebar for electric bicycles, which integrates the brake module and the switch module, simplifies the structure of the entire handlebar, and makes the wiring used for signal transmission neater. Background Technology

[0002] Electric bicycles offer both human and electric propulsion. Users can choose to pedal or use a battery-powered motor to drive the wheels, allowing for greater freedom in choosing their riding method. This reduces physical strain and increases riding distance, achieving a balance between exercise, fitness, and travel, making them popular among modern consumers. Since the motor directly drives the wheels, a throttle switch is located on the handlebars, allowing users to turn or flick the switch to control the bicycle's speed.

[0003] Existing electric bicycles are equipped with both a throttle switch and a brake lever on the handlebars. Users operate the brake lever to reverse the motor, generating a back electromotive force that converts kinetic energy into electrical energy, thus stopping the bicycle. However, the throttle switch and brake lever are usually manufactured by different companies. Therefore, a switch housing and a brake lever housing must be installed separately on the handlebars. The throttle switch is then mounted on the switch housing, and the brake lever on the brake lever housing. Finally, the brake lever housing and switch housing are connected via wiring. This method not only makes wiring difficult but also results in a cluttered overall appearance of the handlebars, making it inconvenient for users to operate the throttle switch and brake lever.

[0004] Therefore, the applicant is considering how to provide a handle structure that integrates the throttle switch and brake lever, making the overall appearance of the handle cleaner and neater, maintaining consistency in appearance, and simplifying the handle structure. Utility Model Content

[0005] Given that the existing handlebar structure of electric bicycles still has many defects, the main purpose of this utility model is to provide a multi-functional handlebar for electric bicycles, which allows the switch module and brake module to be assembled together in a simple structure.

[0006] To achieve the aforementioned main objectives, this utility model provides a multi-functional handlebar for an electric bicycle, comprising a handlebar body, at least one operating component, and a display module. The handlebar body has two opposing grips. The operating component is disposed on the handlebar body and adjacent to either grip. The operating component includes a connecting element, a set of switch modules disposed on one side of the connecting element, a set of brake modules disposed on the other side of the connecting element, and an electronic control module electrically connecting the switch modules and the brake modules. The switch modules are rotatable relative to the connecting element. The display module is disposed on the operating component and electrically connected to the electronic control module.

[0007] Through the aforementioned technical features, the switch module and brake module are integrated into a single operating component via connecting elements. This operating component can be directly mounted on the handlebar body, eliminating the need for separate installation of the switch and brake modules. This improves installation efficiency and enhances the overall aesthetics of the multi-functional handlebar. Furthermore, the electronic control module for signal transmission can be directly connected to the switch and brake modules within the operating component, eliminating the need for additional wiring. Users are also unaffected by wiring interference when operating either the switch or brake module, effectively improving user convenience.

[0008] Preferably, the handlebar body also has a frame, with the grips connected to its two ends respectively. The frame is hollow and has a slot. The operating components are fitted onto the frame, and the wiring harness of the electronic control module passes through the slot into the frame. Therefore, the hollow frame is used to configure the wiring, hiding it and preventing the handlebar body from looking too cluttered.

[0009] Preferably, the connecting element of the operating component has a latching portion, a first locking portion, and a guide groove. The connecting element is pivotally connected to the switch module via the latching portion and assembled to the brake module via the first locking portion. Therefore, the operating component connects the switch module and the brake module with a simple structure, thereby simplifying the structure of the entire multi-functional handle.

[0010] Preferably, the switch module of the operating component includes a switch base, a lever formed on the outer peripheral surface of the switch base, a guide block formed on the inner peripheral surface of the switch base, and a locking segment disposed opposite to the guide block. The guide block passes through the guide groove of the connecting element and can move along the guide groove, and the locking segment abuts against the locking portion of the connecting element. Therefore, when the user operates the lever, the switch base can be rotated, and the guide groove of the connecting element can restrict the movement direction of the guide block, so that the switch module can operate smoothly.

[0011] Preferably, a first torsion spring is also provided between the connecting element and the switch module. One end of the first torsion spring is connected to the inner circumferential surface of the switch base, and the other end is connected to the connecting element. Therefore, when the user releases the lever, the rebound force of the first torsion spring allows the switch base to automatically return to its original position.

[0012] Preferably, the brake module of the operating component includes a brake lever seat, a second locking portion formed on the inner circumferential surface of the brake lever seat, and a brake lever pivotally connected to the brake lever seat, the brake lever being rotatable relative to the brake lever seat. Therefore, based on the user's operation of the brake lever, a signal can be transmitted through the electronic control module to the motor of the electric bicycle, causing the motor to generate a back electromotive force to achieve a braking effect.

[0013] Preferably, a second torsion spring is also provided between the brake lever seat and the brake lever, with one end of the second torsion spring connected to the brake lever seat and the other end connected to one end of the brake lever. Therefore, when the user releases the brake lever, the rebound force of the second torsion spring will allow the brake lever to automatically return to its original position.

[0014] Preferably, the electronic control module of the operating component includes a throttle sensing unit and a brake sensing unit. Therefore, the throttle sensing unit is responsible for detecting the rotation amplitude of the switch socket of the switch module, so that the motor outputs the corresponding force to propel the electric bicycle forward; the brake sensing unit is responsible for detecting the amplitude of the brake lever being pulled, so that the motor outputs the corresponding back electromotive force to cause the electric bicycle to begin to decelerate.

[0015] Preferably, the brake sensing unit has a magnetic element and a Hall sensor element. The magnetic element is disposed at one end of the brake lever, and the Hall sensor element is disposed on the brake lever seat, so that the magnetic element and the Hall sensor element are arranged opposite to each other. Therefore, when the user pulls the brake lever, it will cause the magnetic element to move, thereby causing the magnetic field measured by the Hall sensor element to change. According to the change in magnetic field, the electronic control module outputs a corresponding signal to the motor.

[0016] The detailed structure, features, assembly, and usage of the multi-functional handlebar for electric bicycles provided by this invention will be described in the subsequent detailed description of the embodiments. However, those skilled in the art should understand that these detailed descriptions and the specific embodiments listed for implementing this invention are for illustrative purposes only and are not intended to limit the scope of protection of this invention.

[0059] Please see Figures 1 to 7 The multi-functional handlebar 10 of the electric bicycle provided by this utility model mainly includes a handlebar body 20, an operation component 30 and a display module 40.

[0060] The handlebar body 20 has two grips 21 and a frame 22. The frame 22 may be a hollow tube with a slot 23 on one side, and the two grips 21 are respectively assembled at both ends of the frame 22.

[0061] The operating component 30 is sleeved on the handlebar frame 22 of the handlebar body 20 and is adjacent to any of the grips 21. The operating component 30 has a connecting element 31, a switch module 32, a brake module 33, and an electronic control module 34. It should be noted that since this utility model is mainly applied to electric bicycles, the switch module 32 and the brake module 33 both control the operation of the battery and motor through the electronic control module 34. Therefore, in this embodiment, a single operating component 30 is used to perform the forward and braking actions of the electric bicycle. However, two operating components 30 can also be selected according to actual riding needs, respectively set at both ends of the handlebar frame 22, so that the user can operate the operating component 30 with both hands.

[0062] The connecting element 31 has a locking portion 311, a first locking portion 312, and a guide groove 313, and a first sleeve hole 314 is formed at its center. The locking portion 311 may, for example, have three equidistantly arranged latching members that extend outward from one side of the connecting element 31 and surround the sleeve hole. The first locking portion 312 forms three through holes penetrating both sides of the connecting element 31. The guide groove 313 penetrates both sides of the connecting element 31 and is located relative to the first locking portion 312.

[0063] The switch module 32 includes a switch base 321, a lever 322, a guide block 323, and a locking section 324. A second sleeve hole 325 is formed at the center of the switch base 321. The lever 322 protrudes outward from the outer periphery of one side of the switch base 321 and extends across the entire switch base 321. The guide block 323 protrudes outward from the other side of the switch base 321, located in the area of ​​its inner periphery and adjacent to the second sleeve hole 325. The locking section 324 is disposed on the annular wall surrounding the second sleeve hole 325, dividing the annular wall into a large-diameter area and a small-diameter area.

[0064] Please see Figure 6 During assembly, the insert portion 311 of the connecting element 31 passes through the second set hole 325 of the switch base 321, and the three fasteners are inserted through the small diameter area of ​​the second set hole 325. At this time, the guide block 323 of the switch module 32 passes through the guide groove 313 of the connecting element 31. When the insert portion 311 reaches the large diameter area, it will abut against the insert section 324, making it difficult for the connecting element 31 to be easily separated from the switch module 32, but still allowing the switch module 32 to rotate relative to the connecting element 31. A side cover 326 can also be installed on one side of the switch base 321 to cover the area where the connecting element 31 is connected to the switch base 321.

[0065] A first torsion spring 35 is provided between the connecting element 31 and the switch base 321 of the switch module 32. One end of the first torsion spring 35 is fixed to the inner circumferential surface of the switch base 321, and the other end is fixed to the connecting element 31.

[0066] The brake module 33 includes a brake lever seat 331, a second locking part 332, and a brake lever 333. A third socket 334 is formed at the center of the brake lever seat 331. The second locking part 332 is formed on the inner peripheral surface of the brake lever seat 331, and three locking holes are formed at the three through holes of the first locking part 312 of the connecting element 31. The brake lever 333 is pivotally connected to the outer peripheral surface of the brake lever seat 331 via a pivot member 335, so that the brake lever 333 can rotate relative to the brake lever seat 331.

[0067] During assembly, align the three through holes of the first locking part 312 of the connecting element 31 with the three locking holes of the second locking part 332 of the brake module 33. Then, take three fasteners 336, pass them through the three through holes of the first locking part 312, and lock them into the second locking part 332, so that the connecting element 31 and the brake module 33 are assembled together. It should be noted that this utility model does not particularly limit the number of through holes and locking holes, as long as the connecting element 31 and the brake module 33 can be connected.

[0068] A second torsion spring 36 is provided between the brake lever seat 331 and the brake lever 333. One end of the second torsion spring 36 is fixed to the brake lever seat 331, and the other end is fixed to one end of the brake lever 333.

[0069] The electronic control module 34 includes a throttle sensing unit and a brake sensing unit 341. The throttle sensing unit and brake sensing unit 341 are electrically connected to the electric bicycle's controller via a line 342 for signal transmission. The line 342 passes through a slot 23 in the handlebar frame 22 of the handlebar body 20, thus concealing the line 342 within the handlebar frame 22. The throttle sensing unit is primarily responsible for detecting the rotation amplitude of the switch base 321 in the switch module 32, allowing the electric bicycle's motor to output corresponding force to propel the electric bicycle forward. Since detecting the rotation amplitude of the switch base 321 is prior art, it is not described in detail in this invention. The brake sensing unit 341 includes a magnetic element 3411 and a Hall effect sensor 3412. The magnetic element 3411 is disposed at one end of the brake lever 333, while the Hall effect sensor 3412 is embedded within the brake lever seat 331, with the magnetic element 3411 and the Hall effect sensor 3412 positioned opposite each other. Figure 7 As shown. In this way, when the brake lever 333 is pulled, the position of the magnetic element 3411 will change, and the Hall sensor element 3412 can detect the change in the magnetic field and then transmit the signal to the controller through the line 342.

[0070] The display module 40 is located on the brake lever seat 331 of the operating component 30 and is electrically connected to the line 342 of the electronic control module 34. According to the signal transmitted by the controller of the electric bicycle, the display module 40 will display the current speed of the electric bicycle and other information so that the user can check it at any time.

[0071] When a user actually rides an electric bicycle, they can use their thumb to flick the lever 322 of the switch module 32 of the operating component 30. The lever 322 causes the switch base 321 to rotate relative to the connecting element 31. The guide block 323 of the switch module 32 moves along the guide groove 313 of the connecting element 31, and the first torsion spring 35 is also twisted at the same time. At this time, the throttle sensing unit of the electronic control module 34 detects the degree of rotation of the switch base 321 and outputs a signal to the controller of the electric bicycle through the line 342, so that the battery and motor generate corresponding force to drive the electric bicycle forward. When the user releases the lever 322, the force of the rebound of the first torsion spring 35 can move the switch base 321 back to its original position. According to the change in the position of the switch base 321, the throttle sensing unit also transmits a signal to the controller, so that the battery and motor stop outputting power.

[0072] If the user needs to brake while the electric bicycle is moving forward, they only need to pull the brake lever 333 of the brake module 33 with another finger. When the brake lever 333 is pulled, the second torsion spring 36 is also twisted at the same time, which causes the magnetic element 3411 to move. According to the change in the position of the magnetic element 3411, the Hall sensor element 3412 will detect the change in the magnetic field and then transmit a signal to the controller through the line 342, so that the motor starts to generate back electromotive force to slow down the electric bicycle and achieve the braking function. When the user releases the brake lever 333, the force of the rebound of the second torsion spring 36 will move the brake lever 333 back to its original position. At this time, according to the change in the magnetic field, the Hall sensor unit will detect the return of the magnetic element 3411 to its original position and transmit a signal to the controller, so that the motor stops generating back electromotive force.

[0073] In summary, the multi-functional handlebar 10 for electric bicycles provided by this utility model has at least the following advantages compared with the prior art:

[0074] 1. The multi-functional handlebar 10 of the electric bicycle of this utility model integrates the switch module 32 and the brake module 33 into an operating component 30 through the connecting element 31, so that the operating component 30 can be directly sleeved onto the handlebar body 20, reducing the procedure of separately installing the switch module 32 and the brake module 33, and making the installation easier.

[0075] 2. The multi-functional handlebar 10 of the electric bicycle of this utility model also integrates the electronic control module 34 into the operating component 30, so that the signal transmission line 342 can be configured in the operating component 30. This avoids the line 342 being pulled through the external environment to the switch module 32 and brake module 33, reducing the complexity of the signal line 342, maintaining the overall clean appearance of the multi-functional handlebar 10, and ensuring that the user will not be interfered with by the line 342 when operating the switch module 32 or brake module 33.

[0076] Finally, it must be stated again that the constituent elements disclosed in the above embodiments of this utility model are merely illustrative examples and are not intended to limit the scope of protection of this utility model. Substitutions or variations of other equivalent elements should also be within the scope of protection of this application.
