[0036] Below, this application is described in detail.

[0037] The sealing performance of the brake handle mechanism in the related art is poor, and impurities in the external environment, such as dust and water, can easily enter the brake handle mechanism, affecting the normal operation of the Hall device of the brake handle mechanism, resulting in the brake handle mechanism being unreliable.

[0038] For ease of understanding, the reasons why the sealing of the brake handle mechanism in the related art is poor are analyzed below. The analysis process and conclusions are part of the creativity of this application.

[0039] The brake handle mechanism in the related art includes a fixing seat. During the installation of the Hall device, the Hall device is first fixed on the fixing seat, and then the fixing seat is installed on the brake handle seat. The fixing seat and the brake handle seat are enclosed to form a cavity, and the Hall device is located in the cavity. It is understandable that since the cavity is formed by the fixing seat and the brake handle seat, the integrity is poor, resulting in poor sealing. Impurities in the external environment can easily enter the cavity through the connection between the fixing seat and the brake handle seat, affecting the normal operation of the Hall device.

[0040] The present application provides a means of transportation. The means of transportation may be of various types, for example, a bicycle, an electric bicycle, a balance vehicle, a scooter, or the like.

[0041] Please refer to Figure 1 and Figure 2The scooter in the present application includes a vehicle body and a brake handle device, wherein the vehicle body includes a handlebar, and the brake handle device includes a handle 1, a brake handle seat 2, and a Hall assembly 3. The brake handle seat 2 is fixedly connected to the handlebar and is rotatably connected to the first end 11 of the handle; the brake handle seat 2 is formed with a mounting cavity, which has a first opening 23, and the first opening 23 faces the first end 11 of the handle; the Hall assembly 3 includes a Hall element 31 and a magnetic element 32; the Hall element 31 is used to be electrically connected to the brake mechanism, the Hall element 31 is fixed in the mounting cavity, the direction c of the working surface of the Hall element 31 is the same as the direction of the first opening 23, the magnetic element 32 is fixedly connected to the first end 11 of the handle, and is located on one side of the axis of rotation of the handle 1 relative to the brake handle seat 2, so that the Hall element 31 outputs a signal during the rotation of the handle 1 relative to the brake handle seat 2. With such a structural form, a mounting cavity for mounting the Hall element 31 is formed on the brake handle seat 2, which is beneficial to better the integrity of the mounting cavity, thereby making the mounting cavity more sealed. Impurities in the external environment are not easy to enter the mounting cavity to affect the operation of the Hall element 31, which is beneficial to improving the reliability of the Hall element 31, thereby helping to improve the reliability of the brake handle device.

[0042] The handlebar in the embodiments of the present application has the same meaning as that generally understood by those skilled in the art of the present application. In some embodiments of the present application, a sleeve hole 25 is formed on the brake handle seat 2, and the sleeve hole 25 is coaxially sleeved on the handlebar to fix the brake handle seat 2 with the handlebar, and the axis of the sleeve hole 25 refers to the first axis b in the figure.

[0043] The handle 1 in the embodiment of the present application has the same meaning as that generally understood by those skilled in the art of the present application, and the first end 11 of the handle is rotatably connected to the brake handle seat 2, and the second end 12 of the handle swings relative to the first end during the rotation of the first end 11 of the handle relative to the brake handle seat 2. It can be understood that the second end 12 of the handle is used to be held, and a person can hold the second end 12 of the handle and push it to rotate the first end 11 of the handle relative to the brake handle seat 2 to achieve braking.

[0044] In some embodiments of the present application, the axis of rotation of the handle 1 relative to the brake handle seat 2 may be perpendicular to the extension direction of the handle 1. In this way, it is convenient for a person to push the second end 12 of the handle to make the handle 1 swing relative to the brake handle seat 2, that is, it is convenient for a person to operate the handle 1. The axis of rotation of the handle 1 relative to the brake handle seat 2 can refer to the second axis a in the figure.

[0045] In some embodiments of this application, please refer to Figure 1 and Figure 2 The brake handle device further comprises a pin 4, which is fixed on the brake handle seat 2. A pin hole 111 is formed on the handle 1, and the pin hole 111 is coaxially sleeved on the pin rod of the pin 4, so that the handle 1 is rotatably connected to the brake handle seat 2. In this way, the brake handle device has a simple structure and low cost.

[0046] In some embodiments of this application, please refer to Figure 1 and Figure 2 The brake handle seat 2 is formed with a pin 4 through hole, and the pin rod of the pin 4 is inserted into the pin 4 through hole; the brake handle device also includes a pin nut 7, which is coaxially sleeved on the pin rod of the pin 4 and threadedly matched with the pin rod; along the axial direction of the pin rod, that is, the extension direction of the second axis a, the end faces of the pin cap of the pin 4 and the pin nut 7 close to each other are respectively supported on the end faces at both ends of the pin 4 through hole, so that the pin 4 through hole is fixedly connected to the brake handle seat 2. In this way, the brake handle device has a relatively simple structure and low cost.

[0047] In some embodiments of this application, please refer to Figure 1 and Figure 2 A torque spring is sleeved on the nail rod of the pin 4. One end of the torque spring is connected to the brake handle seat 2 along the circumference of the nail rod, and the other end is connected to the first end 11 of the handle to apply a force to the handle 1 in the circumference of the nail rod, so that the handle 1 is kept in a preset position in the circumference of the nail rod. When the handle 1 is in the preset position, the brake mechanism is in a state of releasing the wheel. When the handle 1 rotates relative to the brake handle seat 2 to overcome the elastic force of the torque spring, the brake mechanism can gradually clamp the wheel to achieve deceleration and braking.

[0048] In some embodiments of this application, please refer to Figure 1 and Figure 2 The brake handle seat 2 is formed with a mounting groove, the mounting cavity is the inner cavity of the mounting groove, and the first opening 23 is aligned with the bottom wall of the mounting groove. In this structural form, the Hall element 31 is arranged in the mounting groove, which is conducive to the stable installation of the Hall element 31 and also conducive to improving the sealing effect of the Hall element 31.

[0049] In some embodiments of this application, please refer to Figure 1 and Figure 2 The brake handle seat 2 includes a first side surface 21, and the working surface 311 is oriented in the same direction as the first side surface 21; two protrusions 22 are arranged on the first side surface 21, and the two protrusions 22 and the first side surface 21 are arranged at intervals along the extension direction of the first side surface 21, and the two protrusions 22 and the first side surface 21 together form a mounting groove. In such a structural form, by making the two protrusions 22 and the first side surface 21 together form the mounting groove, less material is required to form the mounting groove, which is conducive to reducing costs.

[0050] In some embodiments of this application, please refer to Figure 1 and Figure 2, the side wall of the mounting groove includes two opposite second side surfaces; the brake handle device also includes a Hall seat 5, the Hall seat 5 is detachably supported between the two second side surfaces, the Hall seat 5 is formed with a fixed cavity 51, and the Hall element 31 cooperates with the fixed cavity 51. By first installing the Hall element 31 on the Hall seat 5 and then installing it in the mounting groove, it is beneficial to reduce the manufacturing cost. It can be understood that the sealing requirement between the fixed cavity 51 and the Hall seat 5 is relatively high, and the sealing requirement between the mounting cavity and the Hall seat 5 is relatively low. Therefore, the yield of manufacturing the mounting cavity is slightly higher than that of the fixed cavity 51, and the cost of manufacturing the brake handle seat 2 is relatively high compared with the Hall seat 5. The brake handle seat 2 forms the mounting cavity and the Hall seat 5 forms the fixed cavity 51, which is beneficial to improve the yield of the brake handle seat 2, thereby reducing the manufacturing cost. In addition, by detachably supporting the Hall seat 5 between the two second side surfaces, it is also beneficial to improve the stability of the installation of the Hall element 31.

[0051] It can be understood that, in the embodiment of the present application, when the installation groove is surrounded by the two protrusions 22 and the first side surface 21 , the side surfaces on which the two protrusions 22 are close to each other are respectively the two first side surfaces 21 .

[0052] In some embodiments of this application, please refer to Figure 1 and Figure 2 The Hall element 31 can be fixed to the inner wall of the fixing cavity 51 by gluing. This is beneficial to improving the stability of the installation of the Hall element 31 and also to improving the sealing performance.

[0053] In some embodiments of this application, please refer to Figure 1 and Figure 2, the Hall element 31 has an outlet surface 312, and one end of the Hall line of the Hall element 31 is connected to the outlet surface 312; the Hall seat 5 is formed with a fixed groove, and the inner cavity of the fixed groove is a fixed cavity 51; the depth direction of the fixed groove is opposite to the direction d of the outlet surface; the fixed cavity 51 has an extension port 511, and the extension port 511 is aligned with the bottom wall of the fixed groove and matches the Hall element 31, so that the Hall element 31 can extend into the fixed groove through the extension port 511. By allowing the Hall element 31 to extend into the fixed groove through the extension port 511 to cooperate with the installation groove, it is convenient to install the Hall element 31 into the installation groove, and the Hall element 31 is not easily damaged during the installation process. It can be understood that the extension port 511 matches the Hall element 31. When the Hall element 31 is extended into the fixed groove through the extension port 511, the Hall element 31 is extended into the extension port 511 in the opposite direction of the outlet surface 312 and slides relative to the extension port 511. This makes the contact area between the Hall element 31 and the Hall seat 5 smaller in the initial stage of the Hall element 31 extending into the extension port 511. Then, as the extension process continues, the contact area between the Hall element 31 and the Hall seat 5 slowly increases. This helps to reduce the resistance encountered by the Hall element 31 in the process of extending into the extension port 511, thereby facilitating the installation of the Hall element 31 into the installation groove and preventing the Hall element 31 from being damaged during the installation process.

[0054] In the embodiment of the present application, the lead-out surface 312 of the Hall element 31, that is, the side surface of the outer surface of the Hall element 31 used to lead out the Hall line, generally, the Hall element 31 has a prismatic structure, such as a quadrangular prism structure, and the lead-out surface 312 and the working surface 311 are respectively two adjacent and perpendicular sides among the multiple outer side surfaces of the Hall element 31.

[0055] In some embodiments of this application, please refer to Figure 1 and Figure 2 The fixed cavity 51 also has an escape opening 512, which is in the same direction d as the outlet surface and aligned with each other. In this way, the Hall element 31 is exposed outside the fixed cavity 51 through the escape opening 512, so that the Hall element 31 can better sense the position of the magnetic element 32, making the braking process more reliable.

[0056] In some embodiments of this application, please refer to Figure 1 and Figure 2 , the second side surface is arranged opposite to the fixing groove along the depth direction of the fixing groove; a first supporting protrusion 52 is formed on the end surface of the fixing groove away from the bottom wall thereof, the first supporting protrusion 52 faces the second side surface and supports the second side surface, so that there is a gap between the fixing groove and the second side surface, and the Hall line passes through the gap to be electrically connected to the brake mechanism. By allowing the Hall line to pass through the gap to be electrically connected to the brake mechanism, the second side surface and the first supporting protrusion 52 can protect the connection line between the Hall element 31 and the brake mechanism, which is conducive to improving the reliability of the brake handle device.

[0057] In the embodiment of the present application, there is a gap between the fixing groove and the second side surface, which means that there is a gap between the second side surface and the fixing groove in the depth direction of the fixing groove, and the depth direction of the fixing groove points from the second side surface to the inside of the fixing groove.

[0058] In some embodiments of this application, please refer to Figure 1 and Figure 2 The number of the first supporting protrusions 52 is two, and the two first supporting protrusions 52 are arranged along the extension direction of the working surface 311 and are respectively arranged on opposite sides of the mounting groove. By arranging the first supporting protrusions 52 on opposite sides of the mounting groove along the extension direction of the working surface 311, it is beneficial to make the installation of the Hall seat 5 more stable. Moreover, the two first supporting protrusions 52 and the working surface 311 can jointly protect the connecting wire, which is beneficial to improve the reliability of the brake handle mechanism.

[0059] In some embodiments of this application, please refer to Figure 1 and Figure 2 Along the depth direction of the fixing groove, a second supporting protrusion 53 is formed on the end surface of the Hall seat 5 close to the bottom wall of the fixing groove. The second supporting protrusion 53 is arranged corresponding to the fixing groove, and the second supporting protrusion 53 is supported on the second side surface. The second supporting protrusion 53 is arranged to improve the strength of the fixing groove and the reliability of the installation of the Hall element 31.

[0060] In some embodiments of this application, please refer to Figure 1 and Figure 2 The brake handle seat 2 is formed with a receiving cavity 24, and the receiving cavity 24 has a second opening 241; the first end 11 of the handle matches the second opening 241, and the second end extends in a direction away from the receiving cavity 24 along the through direction of the opening; the installation cavity is formed in the receiving cavity 24, or the receiving cavity 24 is the installation cavity, and the second opening 241 is the first opening 23. By forming the receiving cavity 24 on the brake handle seat 2, the installation cavity is formed in the receiving cavity 24, or the receiving cavity 24 is the installation cavity, and the first end 11 of the handle matches the second opening 241 of the receiving cavity 24, on the one hand, the first end 11 of the handle can block the second opening 241, so that external impurities are not easy to enter the receiving cavity 24, and on the other hand, the handle 1 is exposed to the receiving cavity 24 through the second opening 241, so that the Hall element 31 can accurately sense the position of the magnetic element 32.

[0061] In some embodiments of this application, please refer to Figure 3The brake handle device further includes a connecting wire assembly 6, which includes a first connecting section 61. The first end of the first connecting section 61 is connected to the outlet surface 312 of the Hall element 31. The extension direction of the first connecting section 61 is the direction d of the outlet surface; the direction d of the outlet surface is the through direction of the second opening 241, and the second end of the first connecting section 61 extends to the side of the brake handle seat 2 away from the second opening 241. By making the outlet surface direction d the through direction of the second opening 241, and the second end of the first connecting section 61 extends to the side of the brake handle seat 2 away from the second opening 241, the extension path of the connecting wire assembly 6 is relatively smooth, and it can be led out of the accommodating cavity 24 without many bends, which is conducive to reducing the failure rate and improving the reliability of the brake handle device.

[0062] It can be understood that in the embodiment of the present application, the first end of the first connecting section 61 is connected to the line outlet surface 312 of the Hall element 31, that is, the first end of the first connecting section 61 is a Hall line, and at least a part of the first connecting section 61 is a Hall line.

[0063] It should be explained that, generally, the extension direction of the handlebar and the extension direction of the handle 1 match the direction of the second opening 241. After the connecting wire assembly 6 is led out of the accommodating cavity 24, it extends toward the middle of the scooter in the opposite direction of the second opening 241 to be electrically connected to the brake mechanism. In the embodiment of the present application, the direction d of the outlet surface is opposite to the direction of the second opening 241, so that after the connecting wire assembly 6 is led out from the outlet surface 312, it does not need to be bent much, and can be led out of the accommodating cavity 24 in the opposite direction of the second opening 241, which is conducive to reducing the failure rate and improving the reliability of the brake handle device.

[0064] In some embodiments of this application, please refer to Figure 2 and Figure 3 A threading hole 26 is formed on the brake handle seat 2, and the threading hole 26 penetrates the side wall of the accommodating cavity 24 along the thickness direction of the side wall of the accommodating cavity 24, and the connecting wire assembly 6 is led out of the accommodating cavity 24 through the threading hole 26. In some embodiments of the present application, a sealing structure is provided at the threading hole 26, so that the connecting wire assembly 6 and the threading hole 26 are sealed.

[0065] In some embodiments of this application, please refer to Figure 4 and Figure 5, the direction d of the outlet surface is perpendicular to the through direction of the second opening 241, the connecting wire assembly 6 also includes a second connecting section 62 extending along the through direction of the second opening 241, the first end of the second connecting section 62 is connected to the second end of the first connecting section 61, and the second end extends to the side of the brake handle seat 2 away from the second opening 241. With such a structural form, the extension path of the connecting wire assembly 6 is relatively smooth, and it can be led out of the accommodating cavity 24 without a large bend, which is conducive to reducing the failure rate and improving the reliability of the brake handle device. Moreover, the direction d of the outlet surface is perpendicular to the through direction of the second opening 241, which is conducive to reducing the length of the accommodating cavity 24 in the through direction of the second opening 241, thereby facilitating the improvement of the compactness of the structure.

[0066] It should be explained that, generally, the Hall wire is arranged in the accommodating cavity 24 so that the Hall wire can be protected by the brake handle seat 2, one end of the connecting wire is connected to the end of the Hall wire away from the wire outlet surface 312, and the other end extends to the outside of the accommodating cavity 24, and the connecting wire and the Hall wire together constitute a connecting wire assembly 6. Therefore, in the extension direction of the Hall wire, that is, in the direction d of the wire outlet surface, the accommodating cavity 24 needs to have a sufficient length to accommodate the Hall wire, and therefore, making the direction d of the wire outlet surface perpendicular to the through direction of the second opening 241 is conducive to reducing the length of the accommodating cavity 24 in the through direction of the second opening 241, thereby facilitating improving the compactness of the structure.

[0067] In some embodiments of this application, please refer to Figure 4 and Figure 5 The working surface 311 of the Hall element 31 is located on one side of the axis of rotation of the handle 1 relative to the brake handle seat 2, and the working surface 311 faces the axis of rotation of the handle 1 relative to the brake handle seat 2. Such a structural form is conducive to reducing the space occupied by the Hall element 31 and the handle 1, and is conducive to improving the compactness of the structure.

[0068] In some embodiments of this application, please refer to Figure 4 and Figure 5 The outlet surface 312 is parallel to the axis of rotation of the handle 1 relative to the Hall seat 5. By making the outlet surface 312 parallel to the axis of rotation of the handle 1 relative to the Hall seat 5, it is helpful to reduce the length of the accommodating cavity 24 in the extension direction of the second axis a, thereby improving the compactness of the structure.

[0069] In some embodiments of this application, please refer to Figure 4, the connecting wire assembly 6 includes a second connecting section 62; the handlebar and the first end 11 of the handle are arranged along the direction d of the line exiting surface, and the direction d of the line exiting surface is away from the handlebar, the handle 1 includes a first bending section and a second bending section, the first bending section extends along the direction d of the line exiting surface, and the first end is rotatably connected to the brake handle seat 2, the second bending section extends along the through direction of the second opening 241, and the first end is connected to the second end of the first bending section, and the direction of the second opening 241 is from the first end of the second bending section to the second end. By making the handle 1 include the first bending section and the second bending section, the handle 1 can be rotated to a large extent relative to the brake handle seat 2, which is convenient for personnel to operate. By making the direction d of the line exiting surface away from the handlebar, the Hall line corresponds to the first bending section in the through direction of the second opening 241, so that the Hall line can make full use of the space in the accommodating cavity 24 corresponding to the first bending section, which is conducive to improving the compactness of the structure.

[0070] In some embodiments of this application, please refer to Figure 4 and Figure 6 The first end of the second connecting section 62 is located in the accommodating chamber 24 to connect with the first connecting section 61. In this way, the accommodating chamber 24 can better protect the bent portion of the connecting wire assembly 6, which is beneficial to reducing the failure rate and improving the reliability of the brake handle device.
