[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] Please refer to the following Figures 1 to 6 The present invention describes a brake handle assembly and a mobility scooter according to an embodiment of the present invention.

[0033] like Figures 1 to 3As shown, the brake handle assembly of the embodiment of the present invention includes: a brake handle 1, a brake handle seat 2, a clamp 31 and a sensor 4. The brake handle seat 2 is detachably connected to the clamp 31 and forms a fastening cavity 32 for passing the handlebar. A mounting cavity 24 is provided in the brake handle seat 2. The sensor 4 is provided in the mounting cavity 24 for detecting the action state of the brake handle 1. The brake handle 1 is pivotally mounted on the brake handle seat 2, and the brake handle 1 is used to install the brake line. The upper and lower surfaces of any one of the brake handle seat 2, the clamp 31 and the brake handle 1 are symmetrically arranged.

[0034] Taking the brake handle seat 2 as an example, the upper and lower surfaces of the brake handle seat 2 are two wall surfaces of the brake handle seat 2 that are arranged opposite to each other along the thickness direction of the brake handle seat 2.

[0035] According to the brake handle assembly of the embodiment of the present invention, the sensor 4 can detect the operating state of the brake handle 1, thereby improving the reliability of the brake handle assembly during use. In addition, since the upper and lower surfaces of the brake handle seat 2, the clamp 31 and the brake handle 1 are symmetrically arranged, the brake handle assembly does not need to distinguish between left and right during assembly, which is beneficial to improving the versatility of the brake handle assembly and reducing the production and maintenance costs of the brake handle assembly.

[0036] It can be understood that the upper and lower surfaces (front and back) of the brake handle assembly of the embodiment of the present invention have the same appearance, so that the brake handle assembly can be installed on both the left and right handlebars to realize the left and right universal function of the brake handle assembly.

[0037] Alternatively, as Figures 4 to 6 As shown, the brake handle 1 has a rotating portion 111, which is disposed in the mounting cavity 24. The brake handle assembly also includes a connecting shaft 51, which passes through the brake handle base 2 and the rotating portion 111. The rotating portion 111 is rotatable relative to the brake handle base 2 along the axis of the connecting shaft 51. The upper and lower ends of the connecting shaft 51 are symmetrically arranged. It can be understood that the symmetrical arrangement of the upper and lower ends of the connecting shaft 51 allows the connecting shaft 51 to meet the requirements of both the left and right handlebar mounting scenarios.

[0038] For example, one end of the connecting shaft 51 has a detachable first screw 54 , and the end cap of the first screw 54 has the same appearance as the end cap at the other end of the connecting shaft 51 .

[0039] Alternatively, as Figure 5As shown, the brake handle assembly further includes a washer 53, which is sleeved on the connecting shaft 51 and positioned between the brake handle base 2 and the rotating portion 111. For example, two washers 53 may be provided, one on each side of the thickness of the rotating portion 111. By placing the washer 53 between the brake handle base 2 and the rotating portion 111, the brake handle assembly of this embodiment of the utility model can reduce the likelihood of abnormal noise during the rotation of the handle base 11 and mitigate wear and tear between the brake handle base 2 and the handle base 11 during rotation.

[0040] Alternatively, as Figures 4 to 6 As shown, the brake handle seat 2 includes a seat body 21, a thickened portion 22, and a fixed block 23. The thickened portion 22 and the fixed block 23 are both connected to the seat body 21, and the fixed block 23 is arranged adjacent to the thickened portion 22. The thickened portion 22 is rotatably connected to the rotating portion 111. The connecting shaft 51 passes through the thickened portion 22 and the rotating portion 111. The fixed block 23 and the clamp 31 form a fastening cavity 32. It is understandable that the wall thickness of the thickened portion 22 is greater than the wall thickness of the seat body 21. Since the thickened portion 22 is used to connect to the rotating portion 111 and the fixed block 23 is arranged adjacent to the thickened portion 22, the overall structural strength of the brake handle seat 2 can be improved, and the probability of the brake handle seat 2 being damaged due to bumps can be reduced.

[0041] For example, Figure 3 As shown, the hoop 31 and the fixing block 23 are connected by a second fastener 33, which can be a bolt. There are two second fasteners 33, which are arranged on the upper and lower sides of the hoop 31 respectively.

[0042] Alternatively, as Figure 4 and Figure 5 As shown, the sensor 4 includes a Hall element 41 and a magnet 42. The magnet 42 is mounted on the rotating part 111. The Hall element 41 is arranged in the mounting cavity 24 and is detachably connected to the brake handle seat 2. The detection line of the sensor 4 is connected to the Hall element 41 and is led out of the mounting cavity 24.

[0043] When the user operates brake handle 1, brake handle 1 rotates relative to brake handle base 2, and magnet 42 moves synchronously with brake handle 1, allowing magnet 42 to approach and move away from Hall effect element 41. Upon receiving changes in the magnetic field, Hall effect element 41 transmits a sensing signal to the scooter's controller, thereby enabling functions such as starting and stopping the scooter's motor and turning the brake lights on and off. Furthermore, since both Hall effect element 41 and magnet 42 are located within mounting cavity 24, the brake handle assembly is effectively waterproof.

[0044] For example, the Hall element 41 can be fixed to the brake handle seat 2 by a second screw 43 , so that the Hall element 41 can be easily disassembled, assembled, and replaced.

[0045] Furthermore, if Figure 4 and Figure 6 As shown, a mounting groove 114 is provided on the rotating portion 111 . Before the handle base 11 is assembled to the brake handle base 2 , the magnetic block 42 can be fixed to the mounting groove 114 to facilitate the assembly of the magnetic block 42 .

[0046] Alternatively, as Figure 4 and Figure 5 As shown, the brake handle assembly also includes a torsion spring 52, which is sleeved on the connecting shaft 51. A slot is provided on the rotating part 111. One end of the torsion spring 52 is installed in the slot, and the other end of the torsion spring 52 is in contact with the brake handle seat 2. The torsion spring 52 is used to drive the brake handle 1 to automatically reset.

[0047] It can be understood that when the user squeezes the brake handle 1, the brake handle 1 rotates with the axis of the connecting shaft 51 as the rotation axis. Since the torsion spring 52 can drive the brake handle 1 to automatically reset, when the user releases the brake handle 1, the brake handle 1 can drive the handle 12 to reset synchronously under the joint action of the elastic part and the brake line, thereby improving the response speed of the brake assembly and improving the user experience.

[0048] In some embodiments, as Figure 6 As shown, the brake handle 1 includes a handle base 11 and a handle 12. The handle base 11 is used to mount the brake cable and is pivotally mounted on the brake handle base 2. The handle 12 is detachably connected to the handle base 11. If the handle 12 becomes damaged, the operator can replace it independently without disassembling the handle base 11 or the brake cable. Therefore, the brake handle assembly of the present invention is easy to disassemble and assemble, which helps improve after-sales maintenance efficiency.

[0049] Alternatively, as Figure 6 As shown, the handle base 11 is provided with a positioning block 112, and the handle 12 is provided with a positioning groove 121. The positioning block 112 is inserted into the positioning groove 121. The brake handle 1 also includes a first fastener 13, which is passed through the positioning block 112 and the positioning groove 121. It is understandable that the handle 12 and the handle base 11 can be pre-positioned by plugging the positioning block 112 and the positioning groove 121, so as to facilitate the subsequent insertion of the first fastener 13.

[0050] like Figure 6 As shown, the positioning block 112 is movably engaged with the positioning groove 121 along the extension direction of the handle 12. It is understandable that the positioning block 112 and the positioning groove 121 are connected by a snap-fitting manner. When the positioning block 112 and the positioning groove 121 are not fixed by the first fastener 13, the positioning block 112 can be separated from the positioning groove 121 along the extension direction of the handle 12. Since the mutual engagement between the positioning block 112 and the positioning groove 121 has a certain restraining effect, the number of first fasteners 13 can be reduced, thereby facilitating the operator's disassembly and assembly of the handle 12.

[0051] For example, the width of the positioning block 112 gradually decreases in the direction toward the positioning groove 121. It is understandable that the cross-sectional profile of the positioning block 112 gradually decreases in the direction toward the positioning groove 121 to generally form a tapered structure, thereby making it easier for the operator to insert the positioning block 112 into the positioning groove 121, and achieving better guiding and positioning effects.

[0052] Alternatively, as Figure 6 As shown, a clamping block 113 is provided at the end of the positioning block 112 (the inner end of the positioning block 112 adjacent to the positioning groove 121). The inner wall of the positioning groove 121 is provided with a groove (not shown), and the clamping block 113 cooperates with the groove. It can be understood that the mutual cooperation between the clamping block 113 and the groove can further limit the position of the handle 12 and the handle base 11, for example, reducing the amplitude of rotation or shaking of the positioning block 112 relative to the positioning groove 121, which is conducive to improving the firmness of the connection between the handle 12 and the handle base 11.

[0053] In other embodiments, there are two first fasteners 13, and the two first fasteners 13 are connected to both the connecting portion and the mating portion. The two first fasteners 13 can jointly secure the handle 12 and the handle base 11. Compared to a solution using a single first fastener 13, this can improve the anti-torsion effect of the handle 12 and enhance the secure connection between the handle 12 and the handle base 11.

[0054] Alternatively, as Figure 6 As shown, the first fastener 13 includes two first shafts 131, the two first shafts 131 are coaxial and threadedly connected, the end caps of the two first shafts 131 have the same structure, and are respectively arranged on opposite sides of the handle base 11, thereby making the front and back sides of the first fastener 13 the same, so that the brake handle assembly can be installed on the left handlebar or the right handlebar to improve the compatibility of the brake handle assembly.

[0055] Alternatively, as Figure 4 As shown, a brake cable retainer 61 is provided on the handle base 11 and is disposed within the mounting cavity 24. It will be appreciated that the brake cable retainer 61 is used to mount the brake cable. Since the brake cable retainer 61 is located within the mounting cavity 24, it can be concealed, improving the overall appearance of the brake handle assembly and making it less susceptible to damage.

[0056] For example, the brake cable buckle 61 is riveted to the handle base 11 through a rivet 62 .

[0057] A walking vehicle according to another embodiment of the present invention comprises a brake handle assembly according to the present invention. For example, the walking vehicle can be an electric bicycle, a scooter or other types of two-wheeled vehicles.

[0058] According to the mobility scooter of the embodiment of the present invention, the sensor 4 can detect the operating state of the brake handle 1, thereby improving the reliability of the brake handle assembly during use. In addition, since the upper and lower surfaces of the brake handle seat 2, the clamp 31 and the brake handle 1 are symmetrically arranged, the brake handle assembly does not need to be distinguished between left and right during assembly, which is beneficial to improving the versatility of the brake handle assembly and reducing the production and maintenance costs of the brake handle assembly.
