Description

Technical Field

[0001] This application relates to the field of steering control device technology, and more particularly to a steering wheel and a toy car. Background Technology

[0002] Steering wheels are used in various scenarios where directional control is required, such as children's toy cars, go-karts, drift cars, and game consoles. Among related technologies, some steering wheels lack a return-to-center function, while others with a return-to-center function have a large number of parts, a complex structure, and are difficult to assemble. Utility Model Content

[0003] This application provides a steering wheel and a toy car that can both enable the steering wheel to have an automatic return-to-center function and simplify the structure of the steering wheel.

[0004] On one hand, this application provides a steering wheel, which includes: a housing, a fixing member, and a resetting member; wherein, the housing encloses a receiving cavity and has a hand-held portion; the fixing member matches the receiving cavity, is located within the receiving cavity, and is rotatably connected to the housing, and the fixing member can be fixedly connected to a target device; the resetting member is disposed between the fixing member and the housing, and a portion of the resetting member is connected to the fixing member; during the process of the housing rotating relative to the fixing member, the housing causes the resetting member to deform along the rotation direction of the housing relative to the fixing member, so that the resetting member applies a restoring force to the housing, and the housing can rotate to the initial position before rotating relative to the fixing member under the action of the restoring force.

[0005] The steering wheel provided in this application, due to the enclosure formed by the housing, can accommodate a fixing component and a resetting component within the housing. Furthermore, the housing and fixing component can be rotatably connected, allowing the housing to rotate relative to the fixing component, facilitating user grip and rotation of the housing. Simultaneously, the resetting component is positioned between the fixing component and the housing, allowing the housing to drive the resetting component to move relative to the fixing component in the rotational direction. This allows the resetting component to store elastic potential energy, thereby applying a restoring force to the housing, enabling the housing to have an automatic return-to-center function. Moreover, by placing the resetting component within the housing's accommodating cavity, the steering wheel comprises a housing, a fixing component, and a resetting component, reducing the number of components in the steering wheel. Therefore, the steering wheel provided in this application not only provides an automatic return-to-center function but also simplifies the steering wheel's structure.

[0006] In one possible implementation of this application, at least one of the housing and the fixing member is provided with a receiving groove that matches the reset member. The receiving groove extends in the rotation direction, and the reset member is located in the receiving groove. In the rotation direction, one end of the reset member is connected to the fixing member, and the other end of the reset member is connected to the housing.

[0007] In one possible implementation of this application, one of the housing and the fixing member has two stops corresponding to the receiving groove, and the two stops are spaced apart in the receiving groove along the rotation direction. The reset member is located between the two stops, and the two ends of the reset member abut against the two stops respectively along the rotation direction. The other of the housing and the fixing member has two connecting parts corresponding to the receiving groove, and both connecting parts extend into the receiving groove. The two connecting parts correspond to the two ends of the reset member respectively. During the rotation of the housing relative to the fixing member, the connecting parts apply a compressive force to the reset member.

[0008] In one possible implementation of this application, the receiving groove is annular, and two stop portions are evenly distributed in the receiving groove along the rotation direction to divide the receiving groove into two receiving areas. Two connecting portions are evenly distributed in the receiving groove along the rotation direction. The steering wheel includes two reset members, which are located in the two receiving areas respectively.

[0009] In one possible implementation of this application, one of the housing and the fixing member has a stop portion corresponding to the receiving groove, and the stop portion extends into the receiving groove; the steering wheel includes two reset members, which are located on both sides of the stop portion along the rotation direction, and the ends of the two reset members near the stop portion are connected to the stop portion; the other of the housing and the fixing member has two connecting portions corresponding to the receiving groove, and the two connecting portions are detachably abutting against the ends of the two reset members away from the stop portion; during the rotation of the housing relative to the fixing member, one of the two connecting portions applies a tensile force to the reset member that is detachably abutting against one of the connecting portions.

[0010] In one possible implementation of this application, one of the housing and the fixing member is provided with a damping member, and the other of the housing and the fixing member is provided with a damping structure that matches the damping member; during the process of the housing rotating relative to the fixing member to the initial position under the action of restoring force, the damping member and the damping structure cooperate to limit the rotation of the housing relative to the fixing member.

[0011] In one possible implementation of this application, the damping element includes an elastic element, which is fixed to the housing or the fixed element. The elastic element can generate elastic deformation when subjected to external force. The damping structure includes a groove that matches the elastic element. The elastic element is inserted into the groove to limit the rotation of the housing relative to the fixed element.

[0012] In one possible implementation of this application, the damping element is rotatably disposed on one of the housing and the fixing element, and the damping structure includes an arcuate surface disposed on the other of the housing and the fixing element, with the damping element abutting against the arcuate surface.

[0013] In one possible implementation of this application, one of the housing and the fixing member is provided with a first limiting part, and the other of the housing and the fixing member is provided with a second limiting part corresponding to the first limiting part; during the process of the housing rotating relative to the fixing member, the first limiting part and the second limiting part abut against each other to limit the rotation angle of the housing relative to the fixing member.

[0014] In one possible implementation of this application, the steering wheel further includes a detection component, a portion of which is disposed in the housing and another portion of which is disposed in the fixture. The detection component is configured to generate a detection signal in response to the rotation angle of the housing relative to the fixture. The detection signal is used to control the direction of movement of the target device.

[0015] In one possible implementation of this application, the detection component includes a magnetic element and a Hall sensor, with the magnetic element fixed to one of the housing and the fixing element, and the Hall sensor fixed to the other of the housing and the fixing element at a position corresponding to the magnetic element.

[0016] In one possible implementation of this application, the steering wheel also includes a base for fixed connection with the target device, a fastener is fixedly connected to the base, and the housing is rotatable relative to the base.

[0017] On the other hand, this application provides a toy car, which includes: a car body, a running mechanism, and a steering wheel provided by any of the above; wherein the running mechanism is connected to the car body and is capable of moving independently; the steering wheel is fixedly connected to the car body and electrically connected to the running mechanism.

[0018] The toy car provided in this application includes a steering wheel provided by any of the above-mentioned features. Therefore, the steering wheel can have an automatic return-to-center function, and the structure of the steering wheel can be simplified, which is conducive to improving the convenience of controlling the toy car and enhancing the user experience.

[0032] This application provides a steering wheel, as shown in the embodiments below. Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a cross-sectional structural diagram of the steering wheel provided in this application. Figure 2 Schematic diagram of the disassembled structure of the steering wheel provided in this application Figure 1 , Figure 3 Schematic diagram of the disassembled structure of the steering wheel provided in this application Figure 2 The steering wheel provided in this application embodiment can be used in any scenario requiring directional control, such as vehicles (e.g., passenger vehicles, freight vehicles), children's toy cars, go-karts, drift cars, game consoles, etc. This application embodiment does not limit the specific application scenario for this steering wheel. The steering wheel provided in this application embodiment will be described below with reference to examples in the accompanying drawings.

[0033] The steering wheel provided in this embodiment includes: a housing 1, a fixing member 2, and a reset member 3; wherein, the housing 1 encloses a receiving cavity 11 and has a hand grip portion 12; the fixing member 2 matches the receiving cavity 11, the fixing member 2 is located inside the receiving cavity 11 and is rotatably connected to the housing 1, and the fixing member 2 can be fixedly connected to a target device; the reset member 3 is disposed between the fixing member 2 and the housing 1, and a part of the reset member 3 is connected to the fixing member 2; during the process of the housing 1 rotating relative to the fixing member 2, the housing 1 drives the reset member 3 to deform along the rotation direction Z of the housing 1 rotating relative to the fixing member 2, so that the reset member 3 applies a restoring force to the housing 1, and the housing 1 can rotate to the initial position before rotating relative to the fixing member 2 under the action of the restoring force.

[0034] In this embodiment, the housing 1 provides mounting positions and protection for components in the steering wheel, and can be configured with a cavity structure. For example, the housing 1 can be configured to include a matching box 17 and a cover 18, both of which can have grooves. Closing the box 17 and the cover 18 can enclose and form an accommodating cavity 11. The housing 1 can be configured to have a handgrip 12, which can be an annular shape, two symmetrical arc segments, an annular shape formed by connecting an arc segment and a straight segment, etc. The user can hold the steering wheel through the handgrip 12. This embodiment does not limit the specific structure of the housing 1.

[0035] In this embodiment, a fixing member 2 can be provided in the housing 1 to fix the housing 1 to the target device using the steering wheel, so as to install the steering wheel on the target device. For example, a through hole can be provided in the housing 1 so that a part of the fixing member 2 can extend from the receiving cavity 11 of the housing 1 to the outside of the housing 1, so as to fix the fixing member 2 to the target device.

[0036] For example, at least a portion of the accommodating cavity 11 can be configured as a cylindrical cavity, and the fixing member 2 can be configured as a cylinder that matches the cylindrical cavity. Thus, the fixing member 2 can be disposed in the cylindrical cavity portion within the housing 1, thereby allowing the housing 1 to rotate relative to the fixing member 2.

[0037] In this embodiment, a reset member 3 can be provided in the accommodating cavity 11 to apply a restoring force to the housing 1, so that the housing 1 can automatically return to the position before rotation after rotating relative to the fixing member 2.

[0038] For example, the reset member 3 can be disposed within the receiving cavity 11 in the direction of rotation of the housing 1 relative to the fixing member 2. One end of the reset member 3 can be connected to the fixing member 2, and the other end of the reset member 3 can be connected to the housing 1, so that the housing 1 can drive the reset member 3 to move relative to the fixing member 2. The reset member 3 can be made of an elastic material, so that after the reset member 3 moves with the housing 1, the reset member 3 can store elastic potential energy, and a restoring force can be applied to the housing 1 through the reset member 3.

[0039] The steering wheel provided in this embodiment has a housing 11 formed by the shell 1, within which the fixing member 2 and the reset member 3 can be installed. The shell 1 and the fixing member 2 can be rotatably connected, allowing the shell 1 to rotate relative to the fixing member 2, facilitating user grip and rotation of the shell 1. Simultaneously, the reset member 3 is positioned between the fixing member 2 and the shell 1, allowing the shell 1 to drive the reset member 3 to move relative to the fixing member 2 in the rotational direction Z. This allows the reset member 3 to store elastic potential energy, thereby applying a restoring force to the shell 1, enabling the shell 1 to have an automatic return-to-center function. Furthermore, by placing the reset member 3 within the housing 11, the steering wheel comprises the shell 1, the fixing member 2, and the reset member 3, reducing the number of components in the steering wheel. Therefore, the steering wheel provided in this embodiment not only provides an automatic return-to-center function but also simplifies the steering wheel's structure.

[0040] In some possible embodiments of this application, such as Figure 2 As shown, at least one of the housing 1 and the fixing member 2 is provided with a receiving groove 13 that matches the reset member 3. The receiving groove 13 extends along the rotation direction Z. The reset member 3 is located in the receiving groove 13. Along the rotation direction Z, one end of the reset member 3 is connected to the fixing member 2, and the other end of the reset member 3 is connected to the housing 1.

[0041] In this embodiment, a receiving groove 13 matching the reset member 3 can be provided in the housing 1. For example, the receiving groove 13 can be a circular annular groove extending within the housing 1 along the rotational direction Z of the housing 1 relative to the fixing member 2. The fixing member 2 can be positioned at the opening of the receiving groove 13. Alternatively, a receiving groove 13 matching the reset member 3 can be provided on the fixing member 2, with the opening of the receiving groove 13 on the fixing member 2 corresponding to the cavity wall of the receiving cavity 11 of the housing 1. Alternatively, a portion of the receiving groove 13 can be provided on the housing 1, and another portion of the receiving groove 13 can be provided on the fixing member 2. Thus, after the reset member 3 is placed in the receiving groove 13, the fixing member 2 can be rotatably connected to the housing 1, confining the reset member 3 within the receiving groove 13.

[0042] For example, one end of the reset member 3 located in the receiving groove 13 can be fixedly connected to the fixing member 2, and the other end of the reset member 3 can be fixedly connected to the housing 1. In this way, when the housing 1 rotates relative to the fixing member 2 in the rotation direction Z in either a clockwise or counterclockwise direction, the housing 1 can drive the reset member 3 to move relative to the fixing member 2 in the rotation direction Z.

[0043] In the above embodiments, since at least one of the housing 1 and the fixing member 2 is provided with a receiving groove 13 that matches the reset member 3, it is convenient to install the reset member 3 through the receiving groove 13. Furthermore, by extending the receiving groove 13 along the rotation direction Z, the deformation of the reset member 3 along the rotation direction Z can be restricted, thereby ensuring that the restoring force applied by the reset member 3 to the housing 1 is the same as that in the rotation direction Z, which is beneficial to improving the sensitivity of the housing 1 in automatic return to center.

[0044] In some possible embodiments of this application, reference is made to Figure 4 , Figure 4 Top view of the steering wheel structure provided in this application Figure 1 One of the housing 1 and the fixing member 2 has two stop portions 14 corresponding to the receiving groove 13, and the two stop portions 14 are distributed at intervals in the receiving groove 13 along the rotation direction Z. The reset member 3 is located between the two stop portions 14, and the two ends of the reset member 3 along the rotation direction Z abut against the two stop portions 14 respectively. The other of the housing 1 and the fixing member 2 has two connecting portions 21 corresponding to the receiving groove 13. Both connecting portions 21 extend into the receiving groove 13, and the two connecting portions 21 correspond to the two ends of the reset member 3 respectively. During the rotation of the housing 1 relative to the fixing member 2, the connecting portions 21 apply a compressive force to the reset member 3.

[0045] In this embodiment, a stop portion 14 corresponding to the receiving groove 13 can be provided on one of the housing 1 and the fixing member 2, and a connecting portion 21 corresponding to the receiving groove 13 can be provided on the other of the housing 1 and the fixing member 2. The movement of the reset member 3 is restricted by the stop portion 14, and the movement of the reset member 3 is driven by the connecting portion 21.

[0046] For example, two spaced-apart stop portions 14 can be provided on the groove wall corresponding to the receiving groove 13 inside the housing 1. For example, the stop portion 14 can be a protrusion protruding from the groove wall of the receiving groove 13 and extending into the receiving groove 13. Correspondingly, two spaced-apart connecting portions 21 can be provided on the fixing member 2. The connecting portion 21 can be a protrusion protruding from the surface of the fixing member 2 toward the receiving groove 13. After the fixing member 2 is installed with the housing 1, the protrusion can be inserted into the receiving groove 13.

[0047] In another example, two spaced connecting portions 21 can be provided on the groove wall corresponding to the receiving groove 13 within the housing 1. For example, the connecting portion 21 can be a protruding strip from the groove wall of the receiving groove 13, extending into the receiving groove 13. Correspondingly, two spaced stop portions 14 can be provided on the fixing member 2. The stop portions 14 can be protrusions from the surface of the fixing member 2 facing the receiving groove 13, which can be inserted into the receiving groove 13 after the fixing member 2 is installed with the housing 1. The connecting portions 21 and the stop portions 14 are offset along the radial direction of the receiving groove 13, and the connecting portions 21 and the stop portions 14 will not abut against each other during the rotation of the housing 1 relative to the fixing member 2.

[0048] In another example, the reset member 3 can be a compression spring, an elastic rubber strip, or the like. The compression spring can be placed in the receiving groove 13 extending in the rotational direction Z, and confined within the area between the two stop portions 14 of the receiving groove 13. Thus, during the rotation of the housing 1 relative to the fixing member 2, the stop portions 14 can prevent the movement of the end of the compression spring that abuts against the stop portion 14, while the connecting portion 21 applies a force in the rotational direction Z to the end of the compression spring that abuts against the connecting portion 21, thereby compressing and deforming the compression spring, causing it to generate a restoring force.

[0049] In the above embodiments, since the housing 1 and the fixing member 2 are respectively provided with a stop portion 14 extending into the receiving groove 13, the reset member 3 can be restricted within the receiving groove 13 by the stop portion 14 (the two ends of the reset member 3 abut against the two stop portions 14 respectively), and a compressive force can be applied to the reset member 3 by the connecting portion 21, thereby generating a restoring force on the housing 1 in two directions by the same reset member 3.

[0050] In some possible embodiments of this application, such as Figure 4 As shown, the receiving groove 13 is annular, and two stop portions 14 are evenly distributed in the receiving groove 13 along the rotation direction Z to divide the receiving groove 13 into two receiving areas. Two connecting portions 21 are evenly distributed in the receiving groove 13 along the rotation direction Z. The steering wheel includes two reset members 3, which are located in the two receiving areas respectively.

[0051] In this embodiment, the receiving groove 13 can be configured as an annular groove, allowing the two stop portions 14 to be evenly distributed along the circumference (rotation direction Z) of the annular groove, thereby dividing the receiving groove 13 into two semi-circular grooves with the same or nearly the same arc length, thus forming two receiving areas with the same or nearly the same arc length within the receiving groove 13. Furthermore, the two connecting portions 21 are also evenly distributed along the circumference of the annular groove.

[0052] For example, a reset member 3 can be provided in each of the two receiving areas. For instance, the reset member 3 can be a compression spring, which can be pressed into the semi-circular receiving area, and the natural length of the compression spring (its length when not compressed or stretched) is greater than the arc length of the receiving area, so that both ends of the compression spring press against the stop portion 14. Thus, during the rotation of the housing 1 relative to the fixing member 2, the two connecting portions 21 abut against one end of each reset member 3, thereby applying a compressive force to the two reset members 3.

[0053] In the above embodiment, since the receiving groove 13 is divided into two identical or nearly identical receiving areas, the two reset members 3 can be respectively placed in the two receiving areas. Thus, the two reset members 3 can simultaneously apply a restoring force to the housing 1, which helps to improve the speed at which the housing 1 returns to center. Furthermore, during the assembly of the steering wheel, the reset members 3 can be placed into the receiving areas, which helps to reduce the assembly difficulty of the steering wheel.

[0054] In some possible embodiments of this application, one of the housing 1 and the fixing member 2 has a stop portion 14 corresponding to the receiving groove 13, and the stop portion 14 extends into the receiving groove 13; the steering wheel includes two reset members 3, which are located on both sides of the stop portion 14 along the rotation direction Z, and the ends of the two reset members 3 near the stop portion 14 are connected to the stop portion 14; the other of the housing 1 and the fixing member 2 has two connecting portions 21 corresponding to the receiving groove 13, and the two connecting portions 21 are detachably abutted against the ends of the two reset members 3 away from the stop portion 14; during the rotation of the housing 1 relative to the fixing member 2, one of the two connecting portions 21 applies a tensile force to the reset member 3 that is detachably abutted against by the connecting portion 21.

[0055] In this embodiment, a stop portion 14 corresponding to the receiving groove 13 can be provided on one of the housing 1 and the fixing member 2, and a connecting portion 21 corresponding to the receiving groove 13 can be provided on the other of the housing 1 and the fixing member 2. The movement of the reset member 3 is restricted by the stop portion 14, and the movement of the reset member 3 is driven by the connecting portion 21.

[0056] For example, a stop 14 can be provided on the groove wall corresponding to the receiving groove 13 inside the housing 1. For instance, the stop 14 can be a hook protruding from the groove wall of the receiving groove 13, extending into the receiving groove 13. Correspondingly, two opposing connecting parts 21 can be provided on the fixing member 2. The connecting parts 21 can be protrusions protruding from the surface of the fixing member 2 toward the receiving groove 13, which can be inserted into the receiving groove 13 after the fixing member 2 is installed with the housing 1. Alternatively, two opposing protrusions can be provided on the groove wall corresponding to the receiving groove 13 inside the housing 1, serving as connecting parts 21, and a hook serving as the stop 14 can be provided on the fixing member 2. When the housing 1 is in the centered position, the distances between the two connecting parts 21 and the stop 14 are the same or nearly the same.

[0057] In another example, the reset element 3 can be a tension spring or a rubber strip that can be stretched and deformed. One end of each of the two tension springs can be hooked onto the hook that serves as the stop part 14. A raised ring is provided at the end of the tension spring away from the stop part 14. During the installation of the tension spring, the raised ring of the tension spring is positioned on the side of the connecting part 21 away from the stop part 14. Thus, during the relative fixed rotation of the housing 1, one of the two connecting parts 21 abuts against the raised ring of the corresponding tension spring, causing that tension spring to move. The other connecting part 21 separates from the raised ring of the corresponding tension spring and does not cause that tension spring to move.

[0058] In the above embodiment, since one end of each of the two reset members 3 is connected to the same stop part 14, and the other end of each of the two reset members 3 is detachably abutted against a connecting part 21, during the rotation of the housing 1, one of the reset members 3 can be pulled to extend through a connecting part 21 while the other reset member 3 remains stationary. In this way, during the rotation of the housing 1 relative to the fixing part 2 in any direction, a restoring force can be applied to the housing 1, thereby ensuring that the steering wheel can always return to center.

[0059] In some possible embodiments of this application, reference is made to Figure 5 , Figure 5 Top view of the steering wheel structure provided in this application Figure 2 One of the housing 1 and the fixing member 2 is provided with a damping member 4, and the other of the housing 1 and the fixing member 2 is provided with a damping structure 23 that matches the damping member 4; during the process of the housing 1 rotating relative to the fixing member 2 towards the initial position under the action of the restoring force, the damping member 4 cooperates with the damping structure 23 to limit the rotation of the housing 1 relative to the fixing member 2.

[0060] In this embodiment, a damping element 4 can be provided on the housing 1, and correspondingly, a damping structure 23 matching the damping element 4 can be provided on the fixing element 2. Alternatively, a damping structure 23 can be provided on the housing 1, and correspondingly, a damping element 4 matching the damping structure 23 can be provided on the fixing element 2.

[0061] For example, the damping element 4 may include a brush, and the damping structure 23 may include a groove that matches the brush. The bristles of the brush are pressed against the groove. Thus, as the housing 1 rotates towards the initial position under the action of the restoring force, the brush bristles rub against the groove wall, applying resistance to the housing 1 in the opposite direction to the restoring force. After the housing 1 reaches the initial position, the restoring force disappears, and the resistance applied by the brush bristles to the housing 1 prevents the housing 1 from continuing to rotate under inertia, thereby allowing the housing 1 to stop quickly and stably at the initial position.

[0062] In the above embodiments, since damping element 4 and damping structure 23 are respectively provided in the housing 1 and the fixing member 2, during the process of the housing 1 rotating relative to the fixing member 2 towards the initial position, the damping element 4 and damping structure 23 can cooperate to apply resistance to the housing 1, which helps to reduce the occurrence of reciprocating oscillation of the housing 1 after reaching the initial position.

[0063] In some possible embodiments of this application, such as Figure 2 and Figure 5 As shown, the damping element 4 includes an elastic element 41, which is fixed to the housing 1 or the fixing element 2. The elastic element 41 can generate elastic deformation when subjected to external force. The damping structure 23 includes a slot that matches the elastic element 41. The elastic element 41 is inserted into the slot to limit the rotation of the housing 1 relative to the fixing element 2.

[0064] In this embodiment, the damping element 4 can be an elastic component, such as a silicone pillar, silicone block, or rubber pillar. A fixing groove 16 can be provided in the accommodating cavity 11 of the housing 1, matching the elastic element 41. The elastic element 41 can be snapped into the fixing groove 16 to fix it to the housing 1. Correspondingly, a slot corresponding to the elastic element 41 can be provided on the fixing element 2. For example, the groove wall can be arc-shaped, formed by two arc surfaces. Alternatively, a slot can be provided on the cavity wall of the accommodating cavity 11 of the housing 1 to fix the elastic element 41 to the fixing element 2. The extending direction of the slot and the axis of the elastic element 41 are both parallel or nearly parallel to the axis of the rotation direction Z.

[0065] In the above embodiments, since the damping member 4 includes an elastic member 41 and the damping structure 23 includes a slot that matches the elastic member 41, the elastic member 41 can be inserted into the slot to apply resistance to the housing 1, which helps to reduce the reciprocating oscillation of the housing 1 relative to the fixed member 2.

[0066] In some possible embodiments of this application, the damping member 4 is rotatably disposed on one of the housing 1 and the fixing member 2, and the damping structure 23 includes an arcuate surface disposed on the other of the housing 1 and the fixing member 2, with the damping member 4 abutting against the arcuate surface.

[0067] In this embodiment, the circumferential surface of the fixing member 2 can be set as a continuous arc surface. Correspondingly, a damping member 4 is provided on the cavity wall of the receiving cavity 11 of the housing 1. The damping member 4 can be a damping sleeve 42 such as a silicone sleeve or a rubber sleeve. The silicone sleeve or the like can be rotatably set on the cavity wall of the housing 1, and the silicone sleeve is interference-fitted with the arc surface. Alternatively, the cavity wall of the receiving cavity 11 of the housing 1 can be set as an arc surface, and correspondingly, a damping member 4 is rotatably set on the circumferential surface of the fixing member 2. The rotation axis of the damping member 4 and the generatrix of the arc surface are parallel or nearly parallel to the axis of rotation direction Z.

[0068] In the above embodiments, since the damping element 4 can rotate relative to the arc surface, the resistance applied by the damping element 4 to the arc surface can be controlled by controlling the pressure between the damping element 4 and the arc surface. This not only reduces the reciprocating oscillation of the housing 1 relative to the fixed element 2, but also makes it easier to control the magnitude of the resistance encountered by the housing 1 during the return process.

[0069] In some possible embodiments of this application, such as Figure 4 and Figure 5 As shown, one of the housing 1 and the fixing member 2 is provided with a first limiting part 15, and the other of the housing 1 and the fixing member 2 is provided with a second limiting part 22 corresponding to the first limiting part 15; during the process of the housing 1 rotating relative to the fixing member 2, the first limiting part 15 and the second limiting part 22 abut against each other to limit the rotation angle of the housing 1 relative to the fixing member 2.

[0070] In this embodiment, limiting parts can be provided on the housing 1 and the fixing member 2 respectively, so as to limit the rotation angle of the housing 1 relative to the fixing member 2 through the cooperation of the limiting parts, that is, to limit the angle of the steering wheel to rotate clockwise or counterclockwise along the rotation direction Z.

[0071] For example, such as Figure 5As shown, a first limiting part 15 can be provided on the cavity wall of the receiving cavity 11 of the housing 1, and correspondingly, a second limiting part 22 corresponding to the first limiting part 15 can be provided on the fixing member 2. For example, the first limiting part 15 can be a first protrusion protruding radially from the cavity wall of the receiving cavity 11 towards the side close to the fixing member 2, and the second limiting part 22 can be a second protrusion protruding radially from the outer peripheral surface of the fixing member 2, and the first protrusion and the second protrusion partially overlap in the rotation direction Z. Alternatively, a second protrusion serving as the second limiting part 22 can be provided on the housing 1, and a first protrusion serving as the first limiting part 15 can be provided on the fixing member 2. In this way, during the rotation of the housing 1 relative to the fixing member 2, the housing 1 stops rotating until the first limiting part 15 and the second limiting part 22 abut against each other in the rotation direction Z.

[0072] In another example, two first limiting portions 15 can be provided on the cavity wall of the housing 1, and correspondingly, two second limiting portions 22 can be provided on the fixing member 2. Alternatively, one first limiting portion 15 can be provided on the cavity wall of the housing 1, and correspondingly, two second limiting portions 22 can be provided on the fixing member 2. Or, two first limiting portions 15 can be provided on the cavity wall of the housing 1, and correspondingly, one second limiting portion 22 can be provided on the fixing member 2. Furthermore, the rotation angle of the housing 1 relative to the fixing member 2 in a clockwise or counterclockwise direction can be controlled by setting the distance between the first limiting portions 15 and the second limiting portions 22. For example, the rotation angle of the housing 1 relative to the fixing member 2 in a clockwise or counterclockwise direction can be any angle between 0 and 90°. This application embodiment does not limit the rotation angle of the housing 1 relative to the fixing member 2.

[0073] In the above embodiments, since the first limiting part 15 and the second limiting part 22 are respectively provided on the housing 1 and the fixing part 2, the rotation angle of the housing 1 relative to the fixing part 2 can be limited by the cooperation of the first limiting part 15 and the second limiting part 22, thereby limiting the rotation angle of the steering wheel within a suitable range, which is beneficial to improving the accuracy of operation.

[0074] In some possible embodiments of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the steering wheel also includes a detection component 5, a part of which is disposed in the housing 1 and another part of which is disposed in the fixing member 2. The detection component 5 is configured to generate a detection signal in response to the rotation angle of the housing 1 relative to the fixing member 2. The detection signal is used to control the movement direction of the target device.

[0075] In this embodiment, a detection component 5 can be installed in the steering wheel to detect the rotation angle of the housing 1 relative to the fixing member 2. For example, if the detection component 5 comprises two parts, one part of the detection component 5 can be fixed to the housing 1, and the other part of the detection component 5 can be fixed to the fixing member 2, with the two parts of the detection component 5 corresponding to each other. In this way, during the rotation of the housing 1 relative to the fixing member 2, the two parts of the detection component 5 can be driven to generate relative movement, thereby obtaining the rotation angle of the housing 1 relative to the fixing member 2 through the detection component 5.

[0076] For example, the detection component 5 can employ an optical angle sensor, a capacitive angle sensor, a resistive angle sensor, a rotary transformer angle sensor, and an inertial angle sensor. For instance, the detection component 5 can employ an optical angle sensor that includes a light-emitting device and a photosensitive element, such as fixing a gallium arsenide light-emitting diode to the housing 1 and a silicon phototransistor to the fixing member 2, so as to detect the rotation angle of the housing 1 relative to the fixing member 2 by detecting the change in the light emitted by the gallium arsenide light-emitting diode received by the silicon phototransistor.

[0077] In another example, the detection component 5 includes a magnetic element 51 and a Hall sensor 52. The magnetic element 51 is fixed to one of the housing 1 and the fixing member 2, and the Hall sensor 52 is fixed to the other of the housing 1 and the fixing member 2 at a position corresponding to the magnetic element 51. For example, the magnetic element 51 can be fixed to the housing 1. The magnetic element 51 can be a permanent magnet such as a samarium cobalt magnet, neodymium iron boron magnet, ferrite magnet, AlNiCo magnet, or iron-chromium-cobalt magnet, or it can be an electromagnetic element. A matching bracket 53 can be provided for the magnetic element 51 to fix the magnetic element 51 inside the housing 1. A Hall circuit board with a Hall device can be fixed to the fixing member 2, with the Hall circuit board corresponding to the magnetic element 51. Alternatively, the Hall circuit board can be fixed inside the housing 1, and the magnetic element 51 can be fixed to the fixing member 2. In this way, the rotation of the housing 1 relative to the fixing member 2 can be detected by the change in the magnetic field generated by the magnetic element 51 detected by the Hall circuit board (the change in the distance between the magnetic element 51 and the Hall circuit board causes a change in the magnetic field strength near the Hall circuit board).

[0078] In the above embodiments, since a detection component 5 is provided on the housing 1 and the fixing member 2, the rotation angle of the housing 1 relative to the fixing member 2 can be detected by the detection component 5. Thus, the detection signal generated by the detection component 5 according to the size of the rotation angle of the housing 1 relative to the fixing member 2 can be used as a signal to control the movement direction of the target device, which facilitates the control of the movement direction of the target device and helps to improve the control accuracy of the movement direction of the target device.

[0079] In some possible embodiments of this application, such as Figure 1 and Figure 2 As shown, the steering wheel also includes a base 6, which is used to fix the target device. The fastener 2 is fixedly connected to the base 6, and the housing 1 can rotate relative to the base 6.

[0080] In this embodiment, a base 6 can be provided in the steering wheel. For example, the base 6 can be cylindrical, with a protruding ring on it. One end of the base 6 can extend into a through hole in the housing 1 to facilitate its fixed connection with the fixing member 2. The protruding ring can cover the side surface of the housing 1 closest to the base 6. The other end of the base 6 can be configured to match the fixing rod 7 in the target device. For example, a circular hole can be provided at the other end of the base 6 to allow the base 6 to be fitted onto the fixing member 2. The base 6 and the fixing rod 7 can be fixedly connected using screws or the like to install the steering wheel on the target device.

[0081] In the above embodiments, since a base 6 is provided in the steering wheel, it is convenient to install the steering wheel in the target device through the base 6.

[0082] In addition, this application embodiment also provides a toy car, which includes: a car body, a walking mechanism and a steering wheel provided in any of the above embodiments; wherein, the walking mechanism is connected to the car body and can move on its own; the steering wheel fixing member 2 is fixedly connected to the car body and the steering wheel is electrically connected to the walking mechanism.

[0083] In this embodiment, the vehicle body can carry and install other components of the toy car, and can also provide a seating position and space for riders. For example, the vehicle body can be configured to have a passenger compartment, a structure that facilitates riding, or a structure that can change shape. This embodiment does not limit the specific structure of the vehicle body.

[0084] In this embodiment, a walking mechanism can be installed on the vehicle body. For example, the walking mechanism may include a wheeled walking mechanism, a tracked walking mechanism, a legged walking mechanism, etc. If the walking mechanism adopts a wheeled walking mechanism including four tires, the four tires can be set in the four corner areas of the vehicle frame, and two of the tires can be set on the hub motors. In this way, the vehicle frame can be moved by the walking mechanism.

[0085] In this embodiment, the steering wheel provided in any of the above embodiments can be mounted on the vehicle body. For example, a fixing rod 7 can be provided on the vehicle body, the fixing rod 7 can be located at the front end of the vehicle body, and the fixing member 2 can be fixedly connected to the fixing rod 7, or the base 6 can be fixedly connected to the fixing rod 7, so as to mount the steering wheel on the vehicle body.

[0086] For example, the detection component 5 in the steering wheel can be electrically connected to the controller of the toy car, and the controller can be electrically connected to the walking mechanism. In this way, the movement of the walking mechanism can be controlled by the detection signal generated by the detection component 5, thereby controlling the movement direction of the toy car.

[0087] The toy car provided in this application embodiment includes a steering wheel provided in any of the above embodiments. Therefore, the steering wheel can have an automatic return-to-center function, and the structure of the steering wheel can be simplified, which is beneficial to improving the convenience of controlling the toy car and enhancing the user experience.
