Description

Technical Field

[0001] This utility model relates to the field of remote control technology, and in particular to a remote control. Background Technology

[0002] In the field of modern urban transportation and leisure sports, electric scooters are widely loved by consumers for their convenience and flexibility. As a key device for controlling the vehicle's movement, the design and functionality of the electric scooter remote control play a crucial role in the user experience. The remote control acts as an interactive bridge between the user and the scooter, allowing users to easily control the vehicle's start, acceleration, deceleration, and braking, achieving precise control. With the continuous development of the electric scooter market, consumers have increasingly higher demands for remote controls, requiring not only basic control functions but also better performance in terms of ease of operation, comfort, and personalization.

[0003] However, currently available electric scooter remote controls have some design shortcomings. Most existing remote controls have the scroll wheel located on one side, as shown in patent application number CN 213126708U, entitled "A Utility Model Patent for a Remote Control." This design forces users to use only their right hand to rotate the scroll wheel for control. This is extremely inconvenient for left-handed users. This defect severely limits the applicability of the remote controls, failing to meet the diverse needs of different users. Furthermore, prolonged use of the right hand to operate the scroll wheel on one side can lead to right-hand fatigue, affecting the user experience. The single operating method also lacks flexibility and cannot adapt to different usage environments and user habits. Summary of the Invention

[0004] To address the above problems, this application provides a remote control, including a housing, a roller, a PCB circuit board, a wireless communication module, and a battery. The roller is provided with a magnet, and the PCB circuit board is provided with a Hall element. The Hall element and the magnet are arranged opposite to each other and interact to generate an electrical signal. The roller is rotatably disposed at the center of the top of the housing, with its main body located inside the housing and its end exposed at the top of the housing.

[0005] In one embodiment, a reset unit is provided inside the housing. The reset unit includes a reset lever, a reset spring, and a reset protrusion. One end of the reset lever is rotatably disposed inside the housing, and the other end is connected to the reset spring. There are two reset protrusions, which are respectively disposed on both sides of the roller shaft. The reset spring pulls the reset lever to press it against the reset protrusion.

[0006] In one embodiment, a battery support frame is further provided inside the housing, the reset spring is connected to the battery support frame, and the roller and the reset lever are disposed on the battery support frame.

[0007] In one embodiment, a circuit board bracket is provided inside the housing, the PCB circuit board is fixedly mounted on the circuit board bracket, and roller limiting platforms are provided on both sides of the circuit board bracket.

[0008] In one embodiment, a display screen is provided in the middle of the housing, and the display area of ​​the display screen protrudes from the surface of the housing, and the protruding part is an inclined arc-shaped surface.

[0009] In one embodiment, two buttons are provided at the center of the housing, the two buttons are located below the display screen, and the surfaces of the two buttons are recessed into the outer surface of the housing.

[0010] In one embodiment, the outer edge of the roller is provided with anti-slip protrusions.

[0011] In one embodiment, the housing is a flat oval disc-shaped structure, the housing includes a detachably connected upper housing and a lower housing, and the edges of the housing are designed with rounded chamfers.

[0013] The beneficial effects of this utility model are as follows:

[0014] This application discloses a remote control, comprising a housing, a roller, a PCB circuit board, a wireless communication module, and a battery. A magnet is mounted on the roller, and a Hall effect sensor is mounted on the PCB circuit board. The roller is rotatably positioned at the center of the top of the housing, with its main body inside the housing and its end protruding from the top. When the user operates the remote control, they rotate the roller at the exposed top of the housing. The rotation of the roller causes the magnet mounted on it to rotate as well. During the rotation, the magnetic field of the magnet changes, and the Hall effect sensor detects this change and converts it into an electrical signal. After processing by the circuitry on the PCB circuit board, the signal is transmitted wirelessly through the wireless communication module to a paired device (such as an electric scooter), thereby controlling the external device. In this application, the roller is located at the center of the top of the housing, and its central axis coincides with the central axis of the top of the housing, with a symmetrical distribution.

[0029] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0030] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] like Figure 1-3 As shown, a remote control includes a housing 1, a roller 2, a PCB circuit board 3, a wireless communication module, and a battery 4. A magnet 21 is provided on the roller 2, and a Hall element 31 is provided on the PCB circuit board 3. The Hall element 31 and the magnet 21 are arranged opposite to each other and interact to generate an electrical signal. The roller 2 is rotatably disposed at the center of the top of the housing 1, with its main body located inside the housing 1 and its end exposed at the top of the housing 1.

[0032] Specifically, housing 1 provides protection and a mounting base for internal components. Roller 2 is rotatably mounted at the center of the top of housing 1, with most of it located inside the housing 1, only its end exposed at the top. Magnet 21 is fixedly mounted on roller 2 and rotates with it. PCB circuit board 3 is mounted inside housing 1, with Hall effect element 31 on it positioned opposite magnet 21 on roller 2, maintaining a suitable distance for interaction. Battery 4 is installed inside housing 1, powering the various components on PCB circuit board 3 (including Hall effect element 31, wireless communication module, etc.). The wireless communication module, integrated on PCB circuit board 3, is used for signal transmission with external devices (such as electric scooters). When the user operates the remote control, they manually rotate roller 2, which is located at the exposed part of the top of housing 1. The rotation of roller 2 causes the magnet 21 mounted on it to rotate as well. During rotation, the magnetic field of magnet 21 changes, and the corresponding Hall element 31 senses this change and converts it into an electrical signal. After processing by the circuitry on the PCB circuit board 3, this signal is transmitted wirelessly via the wireless communication module to the paired device (such as an electric scooter), thus enabling control of the external device. In this application, roller 2 is located at the center of the top of housing 1, with its central axis coinciding with the central axis of the top of housing 1. This symmetrical arrangement allows for easy operation with either the left or right hand, greatly improving convenience, adapting to different user habits, and expanding the range of applicable users.

[0033] like Figure 4 , 5 As shown, a reset unit 5 is provided inside the housing 1. The reset unit 5 includes a reset lever 51, a reset spring 52, and a reset protrusion 53. One end of the reset lever 51 is rotatably disposed inside the housing 1, and the other end is connected to the reset spring 52. There are two reset protrusions 53, which are respectively disposed on both sides of the rotating shaft of the roller 2. The reset spring (52) pulls the reset lever (51) to press on the reset protrusion (53).

[0034] Specifically, the return spring 52 pulls the return lever 51 to press against the return protrusion 53, keeping it in a pressed state. Whether the user rotates the roller 2 clockwise or counterclockwise, the return spring 52 will pull the return lever 51 to press the return protrusion 53 back to its initial state. Therefore, the return lever 51 can be located above or below the return protrusion 53. That is, when the user rotates the roller 2, whether clockwise or counterclockwise, the return protrusions 53 on both sides of the roller 2's axis will move with the rotation of the roller 2. During rotation, the return protrusion 53 pushes one end of the return lever 51 in contact with it upwards. Since one end of the return lever 51 is rotatably mounted inside the housing 1, it will stretch the return spring 52 connected to the other end of the return lever 51. When the user stops rotating the roller 2, the return spring 52, due to its elasticity, will generate a pulling force, pulling the return lever 51 back to its initial position. This ensures that the roller 2 maintains a consistent reset effect in different operating directions, making it suitable for left- or right-handed use and enhancing the consistency and stability of operation.

[0035] like Figure 2 , 3 As shown in Figure 4, a battery support frame 6 is also provided inside the housing 1. The reset spring 52 is connected to the battery support frame 6, and the roller 2 and the reset lever 51 are provided on the battery support frame 6.

[0036] Specifically, the battery support frame 6 provides a stable mounting base for the reset spring 52, roller 2 and reset lever 51. By concentrating these components on the battery support frame 6, the entire structure becomes more compact and orderly, reducing the shaking and displacement between components and enhancing the stability of the internal structure of the remote control.

[0037] like Figure 2 , 5 As shown in Figures 6 and 7, a circuit board bracket 7 is provided inside the housing 1, and the PCB circuit board 3 is fixedly installed on the circuit board bracket 7. Roller limiting platforms 71 are provided on both sides of the circuit board bracket 7.

[0038] Specifically, a certain clearance is reserved between the roller limiter 71 and the roller 2, allowing the roller 2 to rotate within a set angle range. During rotation, the roller 2 drives the magnet 21 to rotate synchronously. The Hall element 31 senses the change in the magnetic field and generates an electrical signal, which is processed by the PCB circuit board 3 and sent as a control signal through the wireless communication module. When the user continues to rotate the roller 2, gradually increasing its rotation angle, mechanical interference occurs between the roller limiter 71 and the roller 2 when the maximum angle is reached, preventing the roller 2 from continuing to rotate. This avoids damage to internal components due to excessive rotation and improves the reliability of the remote control.

[0039] like Figure 1As shown, a display screen 11 is provided in the middle of the housing 1. The display area of ​​the display screen 11 protrudes from the surface of the housing 1, and the protruding part is an inclined arc-shaped curved surface.

[0040] Specifically, the display screen 11 protrudes from the surface of the housing 1, and the protruding part is an inclined arc-shaped curved surface, which increases the viewing angle of the display screen 11. Users can easily see the information on the display screen in different holding postures and usage scenarios, avoiding visual blind spots caused by angle issues and improving the convenience of users to obtain information.

[0041] like Figure 1 , 6 As shown, two buttons 12 are provided at the center of the housing 1. The two buttons 12 are located below the display screen 11, and the surfaces of the two buttons 12 are recessed into the outer surface of the housing 1.

[0042] Specifically, the button 12 is recessed on the outer surface of the housing 1 to avoid sending incorrect commands due to accidental touch during daily carrying or use, thereby reducing the probability of misoperation caused by unintentional touch and improving the accuracy and reliability of remote control operation.

[0043] like Figure 2 As shown, anti-slip protrusions 22 are distributed circumferentially on the outer edge of the roller 2.

[0044] Specifically, the anti-slip protrusions 22 distributed circumferentially on the outer edge of the scroll wheel 2 increase the friction and control feel between the fingers and the scroll wheel, so that the force applied by the user can be more effectively transmitted to the scroll wheel 2, ensuring that the scroll wheel 2 can rotate smoothly according to the user's intention, thereby achieving precise control of the remote control function.

[0045] like Figure 1 As shown, the shell 1 has a flat oval disc-shaped structure. The shell 1 includes a detachably connected upper shell 13 and a lower shell 14. The edges of the shell 1 are designed with rounded chamfers.

[0046] Specifically, the upper shell 13 and the lower shell 14 are detachably connected, which facilitates production assembly and subsequent maintenance. The rounded chamfer design makes the remote control fit the curve of the hand better when held, improving the user's grip comfort.

[0047] like Figure 1 As shown, the housing 1 is also equipped with an anti-loss rope 15 and a charging port 16.

[0048] Specifically, the design of the anti-loss rope 15 and the charging port 16 enhances the product's practicality, solving problems such as lost remote control and insufficient battery power during use, making it more reassuring and convenient for users.

[0049] This application discloses a remote control, comprising a housing 1, a roller 2, a PCB circuit board 3, a wireless communication module, and a battery 4. A magnet 21 is mounted on the roller 2, and a Hall effect element 31 is mounted on the PCB circuit board 3. The roller 2 is rotatably positioned at the center of the top of the housing 1, with its main body inside the housing 1 and its end protruding from the top of the housing 1. When the user operates the remote control, they rotate the roller 2, which is located at the exposed part of the top of the housing 1. The rotation of the roller 2 causes the magnet 21 mounted on it to rotate as well. During the rotation of the magnet 21, the magnetic field changes, and the corresponding Hall effect element 31 senses this change in magnetic field and converts it into an electrical signal. After processing by the circuit on the PCB circuit board 3, the signal is transmitted wirelessly through the wireless communication module to a paired device (such as an electric scooter), thereby achieving control of the external device. In this application, the roller 2 is located at the center of the top of the housing 1, and the central axis of the roller 2 coincides with the central axis of the top of the housing 1, with a symmetrical distribution. This allows for easy operation whether the user is left- or right-handed, greatly improving ease of operation, adapting to different user habits, and expanding the applicable user group.
