Description

Technical Field

[0001] This utility model relates to the field of electric vehicle braking control technology, and more specifically, it relates to a Hall-effect brake lever with adjustable travel. Background Technology

[0002] Hall effect brake levers are a crucial safety component in electric vehicles. When a user squeezes the brake lever, the magnet inside the lever moves relative to the Hall sensor, causing a change in the magnetic field. The Hall sensor outputs a changing electrical signal to the controller, which then cuts off the power supply to the motor based on the signal, thus achieving power-off braking. This is usually combined with a mechanical braking device for physical braking.

[0003] While existing Hall effect brake levers are widely used, they generally suffer from a problem: the initial trigger stroke (i.e., the displacement required from the initial position to trigger the power-off signal) is fixed and cannot be adjusted according to user habits or actual needs. For users who are accustomed to triggering the power-off with a light touch of the brake, or users with less hand strength, the fixed long stroke may lead to a slow response; while for users accustomed to a larger braking stroke, the fixed short stroke may cause false triggering.

[0004] To address this issue, a Hall effect power-off brake lever with adjustable travel is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a Hall-effect power-off brake lever with adjustable stroke.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a Hall effect brake lever with adjustable stroke, comprising a brake lever body, a brake lever handle at one end of the brake lever body, a rotating handle connected to the end of the brake lever handle near the brake lever body, the rotating handle being hinged to the brake lever body, a magnet being mounted on the rotating handle, and a Hall effect sensor assembly being disposed within the brake lever body; a stroke adjustment mechanism is disposed on the rotating handle, the stroke adjustment mechanism being used to drive the magnet to move relative to the rotating handle, thereby adjusting the relative distance between the magnet and the Hall effect sensor assembly in the initial state.

[0007] The present invention is further configured such that: a displacement groove is provided on the side wall of the rotating handle, and the stroke adjustment mechanism is located in the displacement groove.

[0008] The present invention is further configured such that: the stroke adjustment mechanism includes a screw, a displacement block threadedly connected to the screw, and a torsion wheel disposed at one end of the screw; both ends of the screw are rotatably connected to the inner wall of the displacement groove, and the magnet is mounted on the displacement block.

[0009] The present invention is further configured such that: a cut is provided on the side wall of the brake lever body, and one end of the screw passes through the side wall of the handle and the cut in sequence, and extends to the outside of the brake lever body.

[0010] The present invention is further configured such that the rotating handle is integrally formed or fixedly connected to the brake lever handle, so that the magnet rotates synchronously with the brake lever handle.

[0011] The present invention is further configured such that the brake lever body is provided with scale markings for indicating the travel adjustment position.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] (1) By setting up a travel adjustment mechanism, the user can rotate the torsion wheel to drive the magnet to move relative to the lever, thereby changing the initial distance between the magnet and the Hall sensor in the initial state when the brake lever is not activated. The closer the initial distance, the shorter the brake lever travel required to trigger power-off; conversely, the longer the initial distance, the more travel is required. This allows the user to customize the brake response sensitivity according to their own habits or vehicle characteristics.

[0014] (2) The screw and displacement block are used for threaded transmission. The adjustment process is smooth and precise, and it has a self-locking function. After the adjustment is completed, the position is fixed and reliable and will not change due to vibration or use. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] Please see Figures 1-5 The present invention provides the following technical solution:

[0024] Example 1, see Figures 1-5 A Hall effect brake lever with adjustable travel includes a brake lever body 1, a brake lever handle 2 at one end of the brake lever body 1, a handle 3 connected to the end of the brake lever handle 2 near the brake lever body 1, the handle 3 being hinged inside the brake lever body 1, a magnet 4 being installed on the handle 3, and a Hall effect sensor assembly 5 being provided inside the brake lever body 1.

[0025] The brake lever body 1 has a central structure. The rotating handle 3 is hinged to the inside of the brake lever body 1 via a hinge shaft, and a torsion spring (not shown in the figure) is installed on the hinge shaft. This allows the rotating handle 3 to rotate around the hinge point when the brake lever handle 2 is squeezed. When the brake lever handle 2 is not squeezed, it returns to the initial position due to the properties of the torsion spring.

[0026] The throttle handle 3 and the brake lever handle 2 can be integrally formed or fixedly connected to ensure reliable power transmission. The Hall sensor assembly 5 is fixedly installed in a predetermined position inside the brake lever body 1.

[0027] The handle 3 is provided with a stroke adjustment mechanism 6, which is used to drive the magnet 4 to move relative to the handle 3 in order to adjust the relative distance between the magnet 4 and the Hall sensor assembly 5 in the initial state.

[0028] See Figures 1-5 Furthermore, a displacement groove 31 is provided on the side wall of the handle 3, and the stroke adjustment mechanism 6 is located in the displacement groove 31.

[0029] See Figures 1-5 Furthermore, the stroke adjustment mechanism 6 includes a screw 61, a displacement block 62 threadedly connected to the screw 61, and a torsion wheel 63 disposed at one end of the screw 61; both ends of the screw 61 are rotatably connected to the inner wall of the displacement groove 31, and the magnet 4 is mounted on the displacement block 62.

[0030] See Figures 1-5 Furthermore, the side wall of the brake lever body 1 is provided with a cutout 11, and one end of the screw 61 passes through the side wall of the handle 3 and the cutout 11 in sequence, and extends to the outside of the brake lever body 1.

[0031] In the initial state (without applying the brakes), magnet 4 and Hall sensor assembly 5 maintain an initial distance. The Hall sensor outputs a reference signal to the controller based on the magnetic field strength at this distance.

[0032] When the user squeezes the brake lever 2, the handle 3 rotates accordingly, causing the magnet 4 on it to move around the hinge point. The magnet 4 is displaced relative to the fixed Hall sensor assembly 5, causing a change in the magnetic field between them. When the change in the magnetic field reaches a preset threshold, the Hall sensor assembly 5 outputs a signal change. Upon receiving this signal, the controller cuts off the motor power, achieving power-off braking.

[0033] When adjusting magnet 4, the user rotates torsion wheel 63, which, through screw 61, drives displacement block 62 to move magnet 4 along displacement groove 31 towards the Hall sensor assembly 5. This reduces the initial distance between magnet 4 and Hall sensor assembly 5. Therefore, only a small brake lever movement is needed for the magnetic field change to quickly reach the trigger threshold.

[0034] The torsion wheel 63 is rotated in the opposite direction, causing the displacement block 62, carrying the magnet 4, to move away from the Hall sensor assembly 5. The initial distance increases. At this point, a greater brake lever stroke is required to change the magnetic field to the trigger point.

[0035] The notch 11 is designed so that the user can better twist the screw 61. When the handle 3 rotates, the screw 61 and the torsion wheel 63 do not interfere with the brake lever body 1 and can also rotate with the handle 3.

[0036] See Figures 1-5 Furthermore, the handle 3 is integrally formed or fixedly connected to the brake lever handle 2, so that the magnet 4 rotates synchronously with the brake lever handle 2.

[0037] See Figures 1-5 Furthermore, the brake lever body 1 is provided with scale markings for indicating the travel adjustment position.

[0038] To assist in adjustment, a scale marking can be set on the brake lever body 1, allowing users to precisely control the displacement of the magnet 4 according to the scale markings.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
