While traditional manual control methods are very mature, they are not flexible and convenient enough in certain situations, such as when the driver is physically limited, remote operation is required, or assisted operation in autonomous driving mode. There is an urgent market need for a steering wheel device that can easily achieve remote or automatic control without requiring significant modifications to the original vehicle structure. Utility Model Content

[0003] Therefore, there is a need for a steering wheel device that can be easily controlled remotely or automatically without requiring significant modifications to the original vehicle structure.

[0004] To achieve the above objectives, this embodiment provides a steering wheel device, comprising:

[0005] A boom, the boom being mounted on one side of the steering wheel in the driver's cab of a vehicle;

[0006] A power source, wherein the power source is mounted on the boom; and

[0007] A fixing component is mounted on the power source and is detachably connected to the steering wheel. It rotates with the rotation of the power source, thereby driving the steering wheel to rotate.

[0008] Furthermore, the fixing component includes a fixing plate and a first disassembly component. The fixing plate is detachably connected to the steering wheel via the first disassembly component, and the center of the fixing plate is drively connected to the output end of the power source.

[0009] Furthermore, the fixed disk includes an annular frame and a support plate. The annular frame corresponds to the annular outer frame of the steering wheel, and the support plate corresponds to the spokes of the steering wheel. The support plate is disposed between the left and right sides of the inner ring of the annular frame, and the center of the support plate is the center of the fixed disk. The annular frame is detachably connected to the annular outer frame through the first disassembly component, and / or the support plate is detachably connected to the spokes through the first disassembly component.

[0010] Furthermore, the first disassembly component includes a strap.

[0011] Furthermore, a limiting block is provided on the inner ring of the annular frame, and the limiting block is provided with a first limiting groove for limiting the strap. The strap passes through the first limiting groove to bind the support plate and the annular outer frame together.

[0012] Furthermore, the support plate is provided with at least two second limiting grooves, and the strap passes through the two second limiting grooves to bind the support plate and the spokes together.

[0013] Furthermore, the support plate is also provided with a limiting structure, which limits the steering wheel.

[0014] Furthermore, the limiting structure is an elastic locking structure.

[0015] Furthermore, the elastic locking structure includes a rubber shock absorber and a screw. The screw locks the rubber shock absorber to the support plate. There are multiple elastic locking structures, and two adjacent rubber shock absorbers lock the spokes of the steering wheel.

[0016] Furthermore, the boom includes a support arm and a second detachable component. The second detachable component is located on one end of the support arm and is used for detachable connection with a handle on one side of the steering wheel in the driver's cab. The power source is located on the other end of the support arm.

[0017] Furthermore, the second disassembly component includes a locking hook for locking or unlocking the handle.

[0018] Furthermore, the locking hook includes a hook body, a locking plate, and a rotating plunger positioning pin. The hook body has a receiving opening, and the locking plate is hinged to one side of the hook body located at the receiving opening, for opening the receiving opening to receive the handle, or closing the receiving opening to lock the handle. The rotating plunger positioning pin is disposed on the hook body, and the locking plate has a slot for the rotating plunger positioning pin to extend into. After the rotating plunger positioning pin extends into the slot, the locking plate and the hook body are locked together.

[0019] Furthermore, it also includes a remote control transmitter, a remote control receiver, and a controller. The remote control transmitter is connected to the remote control receiver, the remote control receiver is connected to the controller, and the controller is connected to the power source, which is a motor.

[0020] Unlike existing technologies, the above technical solution has the following beneficial effects:

[0021] The steering wheel can be driven to rotate via a remote power source, enabling precise control of the steering wheel angle. This allows the driver to control the vehicle's direction without directly touching the steering wheel, providing great convenience for vehicle use in special situations (such as remote control in emergencies). The detachable connection between the fixed components and the steering wheel allows for easy installation and removal of the device, increasing its flexibility and meaning the driver can install or remove it as needed.

[0056] Please see Figures 1 to 6 This embodiment provides a steering wheel device, including:

[0057] Boom 1, which is used to be mounted on one side of the steering wheel 4 in the driver's cab of a car;

[0058] Power source 2, mounted on boom 1, is used to drive the rotation of fixed assembly 3; and

[0059] The fixing component 3 is mounted on the power source 2 and is detachably connected to the steering wheel. It rotates with the rotation of the power source 2, thereby driving the steering wheel to rotate.

[0060] Power source 2 is integrated into boom 1 and can be an electric motor or other type of drive unit, such as a hydraulic or pneumatic motor. Fixed assembly 3 is directly connected to power source 2 and can be detachably attached to the steering wheel. This detachable design allows for quick disassembly of the device.

[0061] Users can control the operating status of power source 2 via remote control. The remote control signal is transmitted to power source 2 via wireless communication (such as Bluetooth, Wi-Fi, or infrared). Once a command is received, power source 2 starts and drives fixed component 3 to rotate, thereby causing the steering wheel to rotate and achieving remote control of the vehicle's direction.

[0062] The above technical solution has the following beneficial effects:

[0063] The steering wheel 4 can be rotated via remote power source 2, enabling precise control of the steering wheel 4's rotation angle. This allows the driver to control the vehicle's direction without directly contacting the steering wheel 4, providing great convenience for vehicle use in special situations (such as remote control in emergencies). The detachable connection design between the fixing component 3 and the steering wheel 4 allows for easy installation and removal of the device, increasing its flexibility and meaning the driver can install or remove the device as needed.

[0064] Please see Figure 1 In this embodiment, the fixing component 3 includes a fixing plate 31 and a first disassembly member 32. The fixing plate 31 is detachably connected to the steering wheel 4 via the first disassembly member 32, and the center of the fixing plate 31 is drive-connected to the output end of the power source 2. The fixing plate 31 is designed to be drive-connected to the output end of the power source 2, ensuring that the rotation of the power source 2 can be directly transmitted to the fixing plate 31. The first disassembly member 32 is used to detachably connect the fixing plate 31 to the steering wheel 4. For example, the first disassembly member 32 can be a quick clamp, screw, or clip, etc., so that the fixing plate 31 can be easily and securely installed on the steering wheel 4 and can be easily disassembled as needed.

[0065] Please see Figure 1and Figure 2 In this embodiment, the fixed disk 31 includes an annular frame 311 and a support plate 312. The annular frame 311 corresponds to the annular outer frame 41 of the steering wheel 4, and the support plate 312 corresponds to the spokes 42 of the steering wheel 4. The support plate 312 is located between the left and right sides of the inner ring of the annular frame 311, and the center of the support plate 312 is the center of the fixed disk 31. The annular frame 311 is detachably connected to the annular outer frame 41 through the first disassembly member 32, and / or the support plate 312 is detachably connected to the spokes 42 through the first disassembly member 32.

[0066] Please see Figure 1 and Figure 2 The steering wheel 4 is a circular three-spoke steering wheel, and the support plate 312 is elongated and positioned above the two spokes 42. Optionally, each side of the support plate 312 is detachably connected to a spoke 42 via a first disassembly piece 32, and each side of the annular frame 311 is detachably connected to the annular outer frame 41 via a first disassembly piece 32. A total of four first disassembly pieces 32 can be used. These two first disassembly pieces 32 roughly divide the annular frame 311 into four equal parts, ensuring the even distribution and stable connection of the fixed plate 31 on the steering wheel 4.

[0067] Please see Figure 1 In this embodiment, the first detachment component 32 includes a strap 321. This strap 321 can be a nylon strap, Velcro, elastic band, or other similar flexible material, or it may also have locking buckles. The design of the strap 321 allows the mounting plate 31 to connect to the steering wheel 4 more flexibly and can be adjusted according to the specific size of different steering wheels 4.

[0068] Please see Figure 1 In this embodiment, a limiting block 313 is provided on the inner ring of the annular frame 311, and the limiting block 313 is provided with a first limiting groove 3131 for limiting the strap 321. Figure 1 As shown, the limiting block 313 is U-shaped, and the notch is the first limiting groove 3131. The strap 321 passes through the first limiting groove 3131 to bind the support plate 312 and the annular outer frame 41 together. This design ensures that the strap 321 is fixed in position during use and prevents it from sliding or shifting.

[0069] Please see Figure 2 In this embodiment, the support plate 312 is also provided with a limiting structure 33, which limits the steering wheel 4 and provides additional fixing force to prevent the steering wheel 4 from shifting.

[0070] Please see Figure 2 and Figure 3In this embodiment, the limiting structure 33 is an elastic locking structure. The elastic locking structure can clamp the spokes 42 of the steering wheel 4 with elastic force, thereby further maintaining the stability of the steering wheel 4 and the fixed component 3.

[0071] Please see Figure 3 In this embodiment, the elastic locking structure includes a rubber shock absorber 331 and a screw 332. The screw 332 locks the rubber shock absorber 331 onto the support plate 312. There are multiple elastic locking structures, and two adjacent rubber shock absorbers 331 lock the spokes 42 of the steering wheel 4. Figure 2 As shown, there are a total of 4 elastic locking structures. The two elastic locking structures on the left lock the left spoke 42, and the two elastic locking structures on the right lock the right spoke 42.

[0072] Specifically, such as Figure 3 As shown, the rubber shock absorber 331 can be installed on the support plate 312 in the following manner: the screw 332 passes through the rubber shock absorber 331 and is threadedly connected to the support plate 312. The screw 332 between the rubber shock absorber 331 and the support plate 312 is also provided with a flat washer 335 and a spring washer 334. The end of the screw 332 away from the support plate 312 can be tightened with a nut 333 to tighten the rubber shock absorber 331.

[0073] When the steering device needs to be installed, the user first places the annular frame 311 on the annular outer frame 41 of the steering wheel 4. Since the support plate 312 and the annular frame 311 are integrally formed, the support plate 312 will naturally be positioned above the two spokes 42. Because the support plate 312 is equipped with rubber shock absorbers 331, when the support plate 312 is aligned with the spokes 42, two adjacent rubber shock absorbers 331 clamp one spoke 42 of the steering wheel 4. The elastic design of the rubber shock absorbers 331 can clamp the spokes 42 of the steering wheel 4 while avoiding mechanical damage to the surface of the steering wheel 4. At the same time, the rubber shock absorbers 331 have good shock absorption performance and can absorb and reduce vibration transmission. Next, the strap 321 passes through the first limiting groove 3131 on the annular frame 311 to tie the annular frame 311 and the annular outer frame 41 of the steering wheel 4 together.

[0074] In some embodiments, the support plate 312 is provided with at least two second limiting grooves, and the strap 321 passes through the two second limiting grooves to tie the support plate 312 and the spokes 42 together. One strap 321 may correspond to at least two second limiting grooves. If there are two straps 321, there may be four second limiting grooves.

[0075] When the steering device needs to be installed, the user first places the annular frame 311 on the annular outer frame 41 of the steering wheel 4. Since the support plate 312 and the annular frame 311 are integrally formed, the support plate 312 will naturally be positioned above the two spokes 42. Next, a strap 321 passes through the first limiting groove 3131 on the annular frame 311 to bind the annular frame 311 and the annular outer frame 41 of the steering wheel 4 together. A strap 321 passes through the two second limiting grooves on the support plate 312 to bind the support plate 312 and the spokes 42 of the steering wheel 4 together. The tightness of the strap 321 can be adjusted by adjusting the buckle or Velcro to ensure that the connection between the fixing plate 31 and the steering wheel 4 is both secure and will not damage the steering wheel 4.

[0076] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, the boom 1 includes a support arm 11 and a second detachable component 12. The second detachable component 12 is located at one end of the support arm 11 and is used for detachable connection with the handle 5 on one side of the steering wheel 4 in the driver's cab. A power source 2 is located at the other end of the support arm 11. The support arm 11 can be designed as a metal or plastic rod with a certain length and strength. Figure 1 , Figure 4 As shown, the boom 11 is Z-shaped, with one end fixed to the handle 5 of the steering wheel 4 by a second disassembly component 12 (such as a quick clamp), and the other end is equipped with a power source 2 (such as a motor). This design ensures that the boom 1 can provide sufficient support to drive the fixed component 3 to rotate.

[0077] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, the second disassembly component 12 includes a locking hook for locking or unlocking the handle 5. The locking hook is designed so that the user can lock or unlock the hook through simple operations (such as pressing a button or pulling a lever), thereby achieving quick connection and separation between the boom 1 and the handle 5.

[0078] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the locking hook includes a hook body 121, a locking plate 122, and a rotating plunger positioning pin 123. The hook body 121 has a receiving opening 1211. The locking plate 122 is hinged to one side of the hook body 121 located at the receiving opening 1211, which is used to open the receiving opening 1211 to receive the handle 5, or to close the receiving opening 1211 to lock the handle 5. The rotating plunger positioning pin 123 is provided on the hook body 121. The locking plate 122 has a slot for the rotating plunger positioning pin 123 to extend into. After the rotating plunger positioning pin 123 extends into the slot, the locking plate 122 and the hook body 121 are locked together.

[0079] The hook body 121 is designed as a structure with an opening, which is the receiving port 1211, such as Figure 6 As shown, a handle 5 is used to accommodate the steering wheel 4. A locking plate 122 is hinged to the hook body 121 and can rotate near the receiving opening 1211. A rotating plunger positioning pin 123 is installed in the mounting opening 1212 of the hook body 121 and can control the position of the locking plate 122 by rotating and pressing. When the rotating plunger positioning pin 123 is pressed down and inserted into the slot of the locking plate 122, the locking plate 122 is locked in a closed state, thereby closing the receiving opening 1211 and locking the handle 5. At this point, the locking plate 122 and the hook body 121 press the handle 5 together. In some embodiments, the locking plate 122 and the hook body 121 can be locked together by the spring force.

[0080] In this embodiment, the hook body 121 of the locking hook is hinged to the support arm 11, which allows for better disassembly from the handle 5.

[0081] Please see Figure 7 In this embodiment, the steering wheel device further includes a remote transmitter 6, a remote receiver 7, and a controller 8. The remote transmitter 6 is connected to the remote receiver 7, the remote receiver 7 is connected to the controller 8, and the controller 8 is connected to the power source 2, which is a motor.

[0082] The remote transmitter 6 can be a handheld wireless remote control with multiple buttons or knobs for sending different control commands, such as starting, moving the car forward or backward, turning the car left or right, and stopping. The remote receiver 7 can connect to the remote transmitter 6 via wireless communication technology (such as Bluetooth, Wi-Fi, or infrared) or wired communication technology (such as CAN bus). The controller 8 is typically a microprocessor or embedded control system, responsible for processing the signals received from the remote receiver 7 and controlling the motor's operating state according to preset logic. The motor, acting as the power source 2, generates rotational motion according to the commands of the controller 8, driving the fixed assembly 3 to rotate the steering wheel 4.
