Detailed Implementation

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The following is for reference. Figures 1-4 Describes a handlebar assembly according to an embodiment of the present invention.

[0023] like Figures 1-4 As shown, the handlebar assembly of this utility model embodiment includes a combination switch 1, a throttle 2, a Hall element 3, and a magnet 4.

[0024] Turn 2 and combination switch 1 are rotated as follows Figure 2 The left and right directions are pivotally connected. The combination switch 1 includes a circuit board 11, a Hall element 3 is disposed on the circuit board 11 and electrically connected, and a magnet 4 is disposed on the throttle 2 and is used to electromagnetically sense the Hall element 3. As the magnet 4 rotates with the throttle 2, the Hall element 3 senses the change in the magnetic field of the magnet 4 and converts it into a current of corresponding magnitude, which is then transmitted to the circuit board 11 to control the vehicle speed.

[0025] In this embodiment of the invention, the handlebar assembly, Hall element 3, and circuit board 11 of the combination switch 1 are integrated together to connect to the wiring harness 7. This reduces the number of wiring harnesses required for the handlebar assembly, lowers the risk of poor wiring contact and short circuits, improves the reliability of the handlebar assembly, and also reduces the structural complexity and installation space of the handlebar assembly, facilitating disassembly, assembly, and production. The centralized design of the circuit board improves the operational stability of the Hall device and avoids the problem of device damage caused by the limited internal space of traditional throttles.

[0026] Furthermore, the Hall element 3 can be surface-mounted on the circuit board 11 or soldered onto the circuit board 11 through holes. The Hall element 3 can be a linear Hall element or a programmable Hall element. The Hall element 3 and the magnet 4 can be one or more.

[0027] In some embodiments, the handlebar assembly further includes a connector 5 and an elastic element 6.

[0028] The connecting base 5 is fixedly connected to the combination switch 1, while the throttle 2 is pivotally connected to the connecting base 5. In other words, the connecting base 5 is connected between the throttle 2 and the combination switch 1, and does not pivot with the throttle 2. Figures 1-3 As shown, the connecting base 5 is indirectly connected between the left end of the throttle 2 and the combination switch 1, so that the throttle 2 and the combination switch 1 can be pivotally connected.

[0029] The elastic element 6 connects the throttle 2 and the connecting seat 5, and is used to drive the throttle 2 to pivot. Figure 2 and Figure 3 As shown, the elastic element 6 is preferably, but not limited to, a torsion spring, and is connected between the throttle 2 and the connecting seat 5 to drive the throttle 2 to reset after being rotated by the user. When the throttle 2 is set to unidirectional rotation, the torsion spring is preferably, but not limited to, one; when the throttle 2 is set to bidirectional rotation, the torsion spring is preferably, but not limited to, two.

[0030] The throttle 2 has a magnet 4 at one end (e.g.) Figure 2 The front end shown is located inside the connector 5 so that the magnet 4 is confined between the throttle 2 and the connector 5 to prevent the magnet 4 from falling off, and to make the magnet 4 as close as possible to the Hall element 3 to ensure that the Hall element 3 receives the magnetic field changes of the magnet 4.

[0031] The magnet 4 is positioned relative to the Hall element 3, following the pivoting trajectory of the throttle 2. Figure 3 As shown, this allows the Hall element 3 to receive changes in the magnetic field of the magnet 4 as the throttle 2 pivots, thereby controlling the vehicle speed.

[0032] In some embodiments, the connector 5 is provided with an opening 51 that penetrates the wall, and the opening 51 is disposed opposite to the Hall element 3.

[0033] like Figure 3 As shown, the opening 51 penetrates the wall of the connecting seat 5 and is located between the pivot trajectory of the Hall element 3 and the magnet 4 to ensure that the Hall element 3 receives the magnetic field changes of the magnet 4.

[0034] It is understood that the connector 5 is not limited to having an opening 51. In other embodiments, the portion of the connector 5 located between the pivot trajectory of the Hall element 3 and the magnet 4 is configured as a thin-walled structure.

[0035] In some embodiments, at least a portion of the Hall element 3 is located within the opening 51. This shortens the distance between the Hall element 3 and the magnet 4, which facilitates the Hall element 3 receiving the magnetic field of the magnet 4. Figure 3 As shown.

[0036] In some embodiments, the distance between the magnet 4 and the Hall element 3 is 0.8 mm to 1.2 mm, so that the Hall element 3 can receive the magnetic field of the magnet 4 without affecting the rotation of the throttle 2.

[0037] At least a portion of the Hall element 3 is located within the opening 51, which allows the distance between the magnet 4 and the Hall element 3 to be in the range of 0.8 mm to 1.2 mm.

[0038] In some embodiments, such as Figures 1-3 As shown, the combination switch 1 also includes a housing 12, a circuit board 11 and a Hall element 3 disposed inside the housing 12 for protection by the housing 12.

[0039] The connecting seat 5 is connected to the housing 12 and is at least partially located inside the housing 12, preferably but not limited to being entirely located inside the housing 12. On the one hand, this can shorten the distance between the handlebar 2 and the Hall element 3 so that the Hall element 3 can receive the magnetic field of the magnet 4. On the other hand, it reduces the length of the handlebar assembly and reduces the installation space of the handlebar assembly.

[0040] One end of throttle 2 (e.g.) Figure 2 The outer peripheral surface of the front end shown is provided with an arc-shaped groove 21 extending circumferentially along the throttle 2. The magnet 4 is fitted in the arc-shaped groove 21 to prevent the magnet 4 from detaching.

[0041] Hall element 3 is located at one end of throttle 2 (e.g.) Figure 2 On the outer periphery of the front end shown, in other words, the Hall element 3 and the front end of the throttle 2 are arranged side by side along the radial direction of the throttle 2 so that the Hall element 3 can receive the magnetic field change of the magnet 4 as the magnet 4 pivots with the throttle 2.

[0042] Furthermore, the throttle 2 has a magnet 4 at one end (e.g. Figure 2 The front end shown is located inside the connecting seat 5 so that the front end of the throttle 2 is located inside the housing 12, thereby so that the Hall element 3 and the front end of the throttle 2 are arranged side by side along the radial direction of the throttle 2.

[0043] In some embodiments, the handlebar assembly further includes a wiring harness 7, and the combination switch 1 further includes a button 13. The button 13 is disposed opposite to the circuit board 11 and can trigger the circuit board 11 when pressed. The wiring harness 7 is connected to the circuit board 11 and is used to transmit the electrical signal transmitted by the Hall element 3 to the circuit board 11 and the electrical signal generated by the button 13 triggering the circuit board 11.

[0044] like Figures 1-4As shown, button 13 is mounted on the wall of housing 12 and is movable, so that when button 13 is pressed, it can trigger circuit board 11 to generate a corresponding electrical signal. The electrical signal generated by button 13 triggering circuit board 11 and the electrical signal transmitted to circuit board 11 by element 3 are both transmitted through wiring harness 7, so as to reduce the number of wiring harnesses required to connect the handlebar assembly and reduce the risk of poor wiring harness contact and short circuit.

[0045] Furthermore, the wiring harness 7 includes a protective layer and power lines, ground lines, button signal transmission lines, and Hall signal transmission lines disposed within the protective layer. The power lines and ground lines are used to power the circuit board 11, the button signal transmission lines are used to transmit the electrical signals generated by the button 13 triggering the circuit board 11, and the Hall signal transmission lines are used to transmit the electrical signals transmitted by the Hall element 3 to the circuit board 11.

[0046] Furthermore, multiple buttons 13 are provided for controlling functions such as lights, horn, steering, and cruise control. Preferably, the housing 12 is as follows: Figure 2 The front and rear ends are equipped with buttons 13, and the circuit board 11 is located between the front button 13 and the rear button 13.

[0047] In this embodiment, a separate wiring harness is eliminated from the handlebar assembly structure, breaking through the technical barrier of traditional separate wiring harness transmission for the throttle and combination switch. The connector is set on the circuit board (PCBA), and a single wiring harness is designed to simultaneously achieve the integrated transmission of both types of signals and power from the throttle and combination switch. The signal transmission lines transmit the throttle speed control signal and the combination switch function control signal respectively, and finally connect to the vehicle controller.

[0048] In some embodiments, such as Figures 2-4 As shown, the handlebar assembly also includes a connector 8, which is located at one end of the wiring harness 7 (e.g., Figure 2 (As shown in the front end). The combination switch 1 also includes a housing 12 and a main bracket 14. The main bracket 14 is connected to and housed within the housing 12. The circuit board 11 is mounted on the main bracket 14, thereby fixing the circuit board 11 via the main bracket 14. The connector 8 is plugged into and connected to the main bracket 14, and electrically connected between the wiring harness 7 and the circuit board 11, as shown. Figure 3 and Figure 4 As shown, the main bracket 14 has a plug-in socket, which is plugged into and connected to the plug-in component 8. When the plug-in socket and the plug-in component 8 are plugged into and connected, the end of the plug-in component 8 abuts against the circuit board 11 for electrical connection. The plug-in component 8 is used to fix the wiring harness 7 and to make the wiring harness 7 detachable, so as to facilitate the disassembly, assembly, and maintenance of the wiring harness 7 and the combination switch 1.

[0049] In some embodiments, the connector 8 is fixedly connected to the circuit board 11 inside the combination switch 1, and the fixed connection method can be welding or the like.

[0050] Furthermore, the circuit board 11 is embedded in the main bracket 14 to protect the circuit board 11 through the main bracket 14.

[0051] In some embodiments, the main support 14 has a protrusion 141 with a protective groove 142, and the Hall element 3 is located within the protective groove 142. This is to support and protect the Hall element 3 through the protrusion 141, such as... Figure 4 As shown.

[0052] Furthermore, the groove of the protective groove 142 is positioned opposite to the opening 51.

[0053] In some embodiments, the Hall element 3 is one or more conventional linear or programmable Hall devices, which are surface-mount or through-hole soldered.

[0054] In some embodiments, such as Figure 2 As shown, the combination switch 1 also includes a first silicone pad 15, a second silicone pad 16, a pad bracket 17, and a conductive element 18. The pad bracket 17 is arranged side by side with and connected to the main bracket 14, and the circuit board 11 is located between the pad bracket 17 and the main bracket 14.

[0055] A first silicone pad 15 is provided between the pad bracket 17 and the circuit board 11. The end of the first silicone pad 15 facing the circuit board 11 is provided with a conductive element 18 corresponding to the front button 13. When the front button 13 is pressed, it passes through the pad bracket 17 and squeezes the first silicone pad 15, causing the corresponding conductive element 18 to abut against the circuit board 11, thereby making the circuit board 11 conductive and generating a corresponding electrical signal. After the front button 13 is released from pressing, the corresponding conductive element 18 and / or the first silicone pad 15 push the front button 13 to reset.

[0056] A second silicone pad 16 is provided between the circuit board 11 and the main bracket 14. One end of the second silicone pad 16 facing the circuit board 11 is provided with a conductive element 18 corresponding to the rear button 13. When the rear button 13 is pressed, it passes through the main bracket 14 and squeezes the second silicone pad 16, causing the corresponding conductive element 18 to abut against the circuit board 11, thereby making the circuit board 11 conductive and generating a corresponding electrical signal. After the rear button 13 is released from pressing, the corresponding conductive element 18 and / or the second silicone pad 16 push the rear button 13 to reset.

[0057] Furthermore, the conductive element 18 is preferably, but not limited to, nickel pellets, carbon pellets, or metal dome switches.

[0058] Furthermore, to facilitate the assembly and disassembly of the combination switch 1, the housing 12 is provided with a detachable front end and a detachable rear end, such as... Figure 2 As shown.
