[0031] In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include one or more of such features.
[0032] Please refer to Figures 1 to 3 , the present invention provides an electric vehicle throttle grip, including a handlebar 1, a rotating handle 2 and a speed regulation mechanism 3;
[0033] The speed regulation mechanism 3 includes a housing 31, a sensing component 32, a shielding component 33 and a reset component 34; the sensing component 32, the shielding component 33 and the reset component 34 are respectively arranged inside the housing 31;
[0034] The housing 31 includes an upper housing 311 and a lower housing 312; the interiors of the upper housing 311 and the lower housing 312 are both hollow structures. The upper housing 311 and the lower housing 312 are connected by bolts and form an accommodation space. The left end of the rotation handle 2 extends into the accommodation space and is rotatably connected to the speed regulation mechanism 3. A magnet 21 is provided on the left end face of the rotation handle 2. The handlebar 1 passes through both the upper housing 311 and the lower housing 312 at the same time. A fixing portion 22 is provided at the left end of the rotation handle 2. The fixing portion 22 is arranged in the accommodation space and is clamped with the right side wall of the accommodation space.
[0035] The shielding component 33 is arranged outside the sensing component 32. The shielding component 33 is provided with an opening in the direction towards the magnet 21. The sensing component 32 senses the magnetic field of the magnet 21 through the opening. The free end of the reset component 34 is connected to the rotation handle 2. The reset component 34 provides an elastic force for the rotation handle 2 and resets the rotation handle 2.
[0036] The speed regulation mechanism 3 is arranged at the proximal right end of the handlebar 1. The rotation handle 2 is sleeved outside the right end of the handlebar 1.
[0037] Take Figure 1 as an example. When the user twists the rotation handle 2 counterclockwise, the rotation handle 2 rotates counterclockwise around its axis, changing the orientation of the magnet 21, thereby changing the magnetic field direction. The sensing component 32 converts the sensed magnetic field change into an electrical signal and transmits it to an external throttle control device. When the rotation angles are different, the magnetic field changes are also different. The throttle size can be controlled according to the magnitude of the magnetic field change. By controlling the change of the orientation of the magnet 21 and the rotation angle of the rotation handle 2, the throttle control device is controlled to achieve the purpose of speed regulation. When the user releases the rotation handle 2, the reset device will drive the rotation handle 2 to reset, the orientation of the magnet 21 resets to the original position, and the sensing component 32 transmits the signal to the external throttle control device to achieve the purpose of stopping acceleration.
[0038] In the present invention, a shielding component 33 is provided outside the sensing component 32. Through the shielding component 33, the ability to resist magnetic field interference is enhanced, and the magnetic field of the speed regulation mechanism 3 is prevented from being interfered by the external environment, avoiding the problem of abnormal output voltage, which may cause the electric vehicle to be out of control by the handlebar. The shielding component 33 will shield the interference magnetic fields in other directions. The sensing component 32 located inside the shielding component 32 only senses the magnetic field from the magnet 2 from the opening, making the sensing component 32 more accurately sense the change of the magnetic field of the magnet 21.
[0039] In a specific embodiment, the housing 31 is composed of an upper housing 311 and a lower housing 312, and an accommodation space is formed inside the housing 31; the reset assembly 34 is arranged in the accommodation space, and the handlebar 1 passes through the housing 31 and is rotatably connected to the rotating handle 2. A fixing portion 22 is provided at the left end of the rotating handle 2 for limiting the displacement of the rotating handle 2 in the left and right directions; the rotating handle 2 is rotatably connected to the housing 31 through the fixing portion 22.
[0040] Please refer to Figure 3 , specifically, a placement cavity 313 is provided at the lower end of the lower housing 312, and a card slot 313a is provided in the placement cavity 313, and the sensing assembly 32 is snap-fitted in the card slot 313a.
[0041] The sensing assembly 32 can refer to an existing Hall assembly. When the user holds and rotates the rotating handle 2, the rotating handle 2 drives the magnet 21 to rotate relative to the sensing assembly 32 along with the rotating handle 2, changing the magnetic field inside the housing 31. After the sensing assembly 32 senses the magnetic field change, the output voltage of the sensing assembly 32 changes; the sensing assembly 32 outputs the voltage to the throttle control device to achieve the purpose of adjusting the speed.
[0042] Further, the shielding assembly 33 includes a first shielding plate 331 and a second shielding plate 332;
[0043] The first shielding plate 331 includes a bottom plate 331a and a side plate 331b, and the side plate 331b is vertically connected to the right side of the bottom plate 331a; the bottom plate 331a is located on the lower cavity wall of the placement cavity 313, and the side plate 331b is located on the right cavity wall of the placement cavity 313;
[0044] The second shielding plate 332 is detachably connected to the opening of the placement cavity 313.
[0045] The sensing assembly 32 is arranged in the placement cavity 313. The sensing assembly 32 is located above the bottom plate 331a and to the left of the side plate 331b. The first shielding plate 331 is used to shield magnetic field interference from below and to the right of the sensing assembly 32; the second shielding plate 332 is located to the left of the sensing assembly 32 and is used to shield magnetic field interference from the left of the sensing assembly 32; and, the second shielding plate 332 also serves to seal the placement cavity 313 to prevent sundries from entering through the opening of the placement cavity 313 and causing damage to the sensing assembly 32. In one embodiment, a positioning hole is provided on the side wall of the placement cavity 313, and the second shielding plate 332 is provided with a positioning block adapted to the positioning hole, and the second shielding plate 332 and the placement cavity 313 are snap-fitted through the positioning hole and the positioning block. As a simple replacement, a sliding groove can also be provided at the opening of the placement cavity 313, and the second shielding plate 332 is slidably connected to the placement cavity 313 through the sliding groove to achieve the purpose of detachable connection.
[0046] Preferably, the sensing component 32 is potted in the placement cavity 313. After the sensing component 32 is inserted into the card slot 313a, the placement cavity 313 is potted with silicone potting glue. Potting the sensing component 32 in the placement cavity 313 with silicone potting glue can improve the resistance to external impact and vibration; improve the insulation between internal components and circuits, which is beneficial to the miniaturization and light weight of the device; prevent the sensing component 32 and the circuit from being directly exposed, improve the waterproof and moisture-proof performance of the device, and improve the service performance and stable parameters.
[0047] Furthermore, both the first shielding plate 331 and the second shielding plate 332 are made of iron.
[0048] Due to the magnetic permeability of iron, the first shielding plate 331 and the second shielding plate 332 can resist the interference of the external magnetic field on the sensing component 32, better avoid being interfered by the external magnetic field, and the sensing component 32 can output a voltage according to the change of the magnet 21 in the rotating handle 2, making the acceleration process more stable and achieving a safer driving effect.
[0049] Specifically, the reset component 34 includes a torsion spring 341 and a fixing ring 342;
[0050] The rotating handle 2 is provided with a torsion spring groove, and the torsion spring 341 is located in the torsion spring groove; one end of the torsion spring 341 is fixed to the torsion spring groove, and the other end extends out of the torsion spring groove;
[0051] The fixing ring 342 is sleeved on the outside of the handlebar 1; the fixing ring 342 is provided with a limiting block 342a, and the limiting block 342a limits the movement of the other end of the torsion spring 341.
[0052] The electric vehicle throttle grip realizes the reset of the rotating handle 2 through the torsion spring 341 and the fixing ring 342. When the user twists the rotating handle 2, the torsion spring 341 is driven to rotate; the other end of the torsion spring 341 abuts against the limiting block 342a on the fixing ring 342. When the user continues to twist, the rotating handle 2 does work on the torsion spring 341, causing the torsion spring 341 to generate torque; when the user releases the rotating handle 2, the torsion spring 341 uses the limiting block 342a as a fulcrum to drive the rotating handle 2 to rotate in the opposite direction, resetting the handle.
[0053] In a specific embodiment, a handle rubber 23 is sleeved on the outside of the rotating handle 2, and the surface of the handle rubber 23 is provided with anti-slip patterns 231. The rotating handle 2 is sleeved with the handle rubber 23, which makes the rotating handle 2 have a better feel and improves the user experience. At the same time, the surface of the handle rubber 23 can be provided with anti-slip patterns 231 to enhance the friction force, enabling the user to better hold the rotating handle 2 and avoid the problem that the rotating handle 2 cannot be twisted due to hand slipping and thus cannot be accelerated.
[0054] The technical principles of the present invention have been described in conjunction with specific embodiments. These descriptions are only for explaining the principles of the present invention and cannot be construed as limiting the protection scope of the present invention in any way. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present invention without creative efforts, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
