[0043] First, as Figure 1 、 Figure 2 and Figure 3 As shown, the electric steering wheel 10 provided in an embodiment of the present application includes a steering wheel base 11, a motor 12, a steering wheel cover 21, an elastic member 22, a first conductive member 23, and a second conductive member 24. The motor 12 includes a motor housing 121 and an output shaft 122. The output shaft 122 is connected to the steering wheel base 11 and is used to drive the steering wheel base 11 to rotate. The steering wheel cover 21 covers the steering wheel base 11 and is capable of moving relative to the steering wheel base 11 in a first direction X. The elastic member 22 is disposed between the steering wheel base 11 and the steering wheel cover 21. The first conductive member 23 is disposed on the motor housing 121 and is insulated from the motor housing 121. The first conductive member 23 is used to electrically connect to the speaker. The second conductive member 24 is electrically connected to the motor housing 121 and is disposed between the steering wheel cover 21 and the first conductive member 23 along the first direction X. The steering wheel cover 21 can drive the second conductive member 24 to switch between a first state and a second state. In the first state, the second conductive member 24 contacts and is electrically connected to the first conductive member 23 . In the second state, the second conductive member 24 is separated from the first conductive member 23 .

[0044] The electric steering wheel 10 can be used in a vehicle 1 and mounted on a steering wheel bracket in the vehicle 1. The motor 12 includes a motor housing 121 and an output shaft 122. The output shaft 122 can be connected to the steering wheel base 11 via a bearing or other structure. Based on the real-time environmental conditions during vehicle 1 operation, the relevant control module in the vehicle 1 controls the motor 12 to drive the steering wheel base 11 and the steering wheel cover 21 to rotate together. The rotation angle of the steering wheel base 11 and the steering wheel cover 21 is controlled according to the control signal of the control module to realize the autonomous driving function of the vehicle 1.

[0045] The steering wheel cover 21 covers the steering wheel base 11 and can move along the first direction X relative to the steering wheel base 11. The steering wheel cover 21 and the steering wheel base 11 can be snap-connected, and the steering wheel cover 21 has the freedom to move along the first direction X relative to the steering wheel base 11.

[0046] The elastic member 22 is disposed between the steering wheel base 11 and the steering wheel cover 21. When the steering wheel cover 21 is pressed, the steering wheel cover 21 is displaced relative to the steering wheel base 11 in the first direction X toward the second conductive member 24, causing the elastic member 22 to deform. After the pressing force applied to the steering wheel cover 21 is removed, the elastic force of the elastic member 22 drives the steering wheel cover 21 to displace relative to the steering wheel base 11 in the first direction X away from the second conductive member 24. Alternatively, the elastic member 22 may be a spring, etc.

[0047] The first conductive member 23 can be a metal member and is provided on the motor housing 121 and insulated from the motor housing 121. The motor housing 121 provides support for the first conductive member 23. In the second state, there is no electrical connection between the first conductive member 23 and the motor housing 121. In this way, the speaker will not make any sound.

[0048] The first conductive member 23 is used to be electrically connected to the horn. The horn may be provided on the body of the vehicle 1 , and the first conductive member 23 may be electrically connected to the horn via a conductive structure or the like.

[0049] The second conductive member 24 is electrically connected to the motor housing 121. Optionally, the second conductive member 24 may directly contact and electrically connect to the motor housing 121, or the second conductive member 24 may be electrically connected to the motor housing 121 via a conductive structure. The second conductive member 24 is electrically connected to the motor housing 121. Since the motor housing 121 is electrically connected to the body of the vehicle 1, the second conductive member 24 is electrically connected to the body in both the first state and the second state, and is further electrically connected to the horn.

[0050] The steering wheel cover 21 can drive the second conductive member 24 to switch between the first state and the second state. Therefore, the steering wheel cover 21 can move relative to the steering wheel base 11 under an external force and drive the second conductive member 24 to switch between the first state and the second state.

[0051] The conversion between the first state and the second state of the second conductive member 24 can be a change in the shape of the second conductive member 24. For example, the second conductive member 24 is elastic, and the steering wheel cover 21 drives the second conductive member 24 to produce elastic deformation to achieve the conversion of the second conductive member 24 between the first state and the second state. Alternatively, the conversion between the first state and the second state of the second conductive member 24 can be a displacement change of the second conductive member 24. For example, the steering wheel cover 21 drives the second conductive member 24 to produce displacement along the first direction X to achieve the conversion of the second conductive member 24 between the first state and the second state. Of course, the conversion between the first state and the second state of the second conductive member 24 can also be that the second conductive member 24 produces both deformation and displacement. It can be set according to specific needs.

[0052] It is understood that when no force is applied to the steering wheel cover 21, the steering wheel cover 21 is in a natural state relative to the steering wheel base 11, and the second conductive member 24 is in the second state. When the steering wheel cover 21 is pressed, the steering wheel cover 21 moves toward the second conductive member 24 along the first direction X and applies a force to the second conductive member 24, causing the second conductive member 24 to transition from the second state to the first state, where it contacts and electrically connects with the first conductive member 23.

[0053] Since the second conductive member 24 is electrically connected to the motor housing 121, the first conductive member 23 is used to electrically connect to the horn of the vehicle 1. The motor housing 121 can be electrically connected to the vehicle body, while the horn is electrically connected to the vehicle body and the first conductive member 23. In this way, when the first conductive member 23 and the second conductive member 24 are in contact and electrically connected, the circuit that drives the horn to produce sound forms a closed loop, thereby driving the horn to produce sound. In other words, when the second conductive member 24 is in the first state, the horn of the vehicle 1 can produce sound.

[0054] After the steering wheel cover 21 is released, the steering wheel cover 21 moves in the first direction X away from the second conductive member 24. The second conductive member 24 switches from the first state to the second state. The second conductive member 24 separates from the first conductive member 23, disconnecting the circuit for driving the horn to sound. The horn no longer sounds. In other words, when the second conductive member 24 is in the second state, the horn of the vehicle 1 does not sound.

[0055] The first conductive member 23 can be in various shapes. The electric steering wheel 10 can include one, two, or more first conductive members 23. Each of the first conductive members 23 can be in contact with and electrically connected to the second conductive member 24 to trigger the horn to sound.

[0056] Optionally, the electric steering wheel 10 may include one or more second conductive members 24 , which may be arranged in a circular array so that any one of the second conductive members 24 in contact with and electrically connected to the first conductive member 23 may trigger the horn to sound.

[0057] The first conductive member 23 is located in the motor housing 121 and is insulated from the motor housing 121. Replacing multiple conductive wires with the first conductive member 23 helps reduce the wiring harness inside the electric steering wheel 10, thereby simplifying the internal structure of the electric steering wheel 10, facilitating the assembly and maintenance of the electric steering wheel 10, and helping to reduce the risk of abnormal noise inside the electric steering wheel 10.

[0058] Therefore, the electric steering wheel 10 provided in the embodiment of the present application, by disposing the first conductive member 23 in the motor housing 121 and isolating it from the motor housing 121, and providing the second conductive member 24, can be switched between a first state and a second state, thereby facilitating the electric steering wheel 10 to trigger the horn to sound or not sound. The placement of the first conductive member 23 in the motor housing 121 helps simplify the wiring harness arrangement within the electric steering wheel 10, reduces the risk of abnormal noise generated by the electric steering wheel 10 under vibration or impact loads, and helps simplify the internal structure of the electric steering wheel 10, facilitating assembly and maintenance of the electric steering wheel 10.

[0059] In some embodiments, as Figure 2 As shown, the first conductive member 23 is annular and is disposed around the rotation axis of the steering wheel base 11 .

[0060] In this way, a first conductive member 23 can be aligned with multiple second conductive members 24 along the first direction X. When any second conductive member 24 is driven by the steering wheel cover 21 to switch to the first state, it can trigger the horn to sound. This helps further simplify the internal structure of the electric steering wheel 10 and improves the sensitivity of the electric steering wheel 10 in triggering the horn to sound.

[0061] In some embodiments, as Figure 5 As shown, the motor 12 includes a connector 123 , which is provided on the motor housing 121 and is used to be electrically connected to the speaker. The first conductive member 23 is electrically connected to the connector 123 .

[0062] The first conductive member 23 is electrically connected to the connector 123 . Optionally, the first conductive member 23 may be directly connected to the connector 123 , or the first conductive member 23 may be electrically connected to the connector 123 via an intermediate conductive structure.

[0063] The connector 123 can be a structure such as an aviation plug. The connector 123 is electrically connected to the first conductive member 23 and is used to electrically connect to the speaker. This is beneficial to improving the convenience of the electrical connection between the first conductive member 23 and the speaker and simplifying the structure and process of the electrical connection between the first conductive member 23 and the speaker.

[0064] In some embodiments, as Figure 5 As shown, the electric steering wheel 10 further includes a wire 14 , which electrically connects the first conductive member 23 and the connector 123 .

[0065] Optionally, the wire 14 may be passed through the interior of the motor 12 , or the wire 14 may be wound around the exterior of the motor 12 .

[0066] The provision of the conductive wire 14 is beneficial for improving the convenience of connecting the first conductive member 23 and the connector 123 , and the position of the connector 123 or the first conductive member 23 can be flexibly set as needed.

[0067] In some embodiments, as Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the electric steering wheel 10 also includes an insulating member 13, and the first conductive member 23 includes a conductive body 231 and a conductive contact portion 232. The conductive body 231 is annular and is arranged around the rotation axis of the steering wheel seat 11. The conductive contact portion 232 protrudes relative to the conductive body 231 toward the second conductive member 24, and contacts and is electrically connected to the wire 14. The insulating member 13 is arranged between the conductive body 231 and the motor housing 121.

[0068] The conductive contact portion 232 can be electrically connected to the speaker through a wire 14 or the like. For example, one end of the wire 14 is welded to the conductive contact portion 232 , and the other end is used to electrically connect to the speaker.

[0069] The conductive contact portion 232 is protruded relative to the conductive body 231 and faces away from the second conductive member 24 to facilitate electrical connection between the conductive contact portion 232 and the speaker. In the first state, the second conductive member 24 can contact and electrically connect with the conductive body 231 .

[0070] The insulating member 13 is disposed between the conductive body 231 and the motor housing 121 , so as to insulate the first conductive member 23 from the motor housing 121 through the insulating member 13 , thereby reducing the risk of electrical connection between the first conductive member 23 and the motor housing 121 .

[0071] Therefore, such a configuration facilitates reducing the risk of electrical connection between the first conductive member 23 and the motor housing 121 while achieving electrical connection between the first conductive member 23 and the speaker.

[0072] In some embodiments, as Figure 2and Figure 3 As shown, the steering wheel cover 21 includes a cover body 211 and a protrusion 212. The protrusion 212 is protruded relative to the cover body 211 along the first direction X toward the steering wheel seat 11. Along the first direction X, at least part of the second conductive member 24 is arranged between the protrusion 212 and the first conductive member 23.

[0073] Optionally, the protrusion 212 may be in a block shape, a column shape, or other shapes.

[0074] In this way, when the steering wheel cover 21 moves relative to the steering wheel seat 11 along the first direction X toward the second conductive member 24, the protrusion 212 pushes the second conductive member 24 to move, so as to convert from the second state to the first state, which is beneficial to simplify the structure of the steering wheel cover 21 and reduce the weight of the steering wheel cover 21.

[0075] In some embodiments, as Figure 4 and Figure 6 As shown, the second conductive member 24 is cantilevered, one end of the second conductive member 24 is connected to the steering wheel seat 11, and the other end is a free end 24a, which is arranged between the protrusion 212 and the first conductive member 23. In the first state, the protrusion 212 is used to press against the free end 24a to make the second conductive member 24 contact with the first conductive member 23.

[0076] One end of the second conductive member 24 is connected to the steering wheel base 11, and through the steering wheel base 11, it is electrically connected to the motor housing 121, and thus to the body of the vehicle 1. The second conductive member 24 is arranged in a cantilever configuration, with one end of the second conductive member 24 being a free end 24a. The protrusion 212 is used to abut the free end 24a to bring the second conductive member 24 into contact with the first conductive member 23. Due to the cantilever configuration of the second conductive member 24, the free end 24a can undergo significant deformation under the abutment of the protrusion 212, facilitating contact and electrical connection between the second conductive member 24 and the first conductive member 23.

[0077] Therefore, such an arrangement facilitates the electrical connection between the second conductive member 24 and the first conductive member 23 and helps to simplify the structure of the second conductive member 24 .

[0078] In some embodiments, the second conductive member 24 includes a metal spring.

[0079] It is understandable that when the electric steering wheel 10 has multiple second conductive members 24 , all of the second conductive members 24 can be metal springs, or only some of the second conductive members 24 can be metal springs, and the specific selection can be made according to actual needs.

[0080] The metal dome has a certain degree of elasticity. Thus, when the steering wheel cover 21 moves relative to the steering wheel base 11 toward the second conductive member 24, the metal dome deforms and is pushed toward the first conductive member 23 by the protrusion 212. The metal dome transitions from the second state to the first state and becomes electrically connected to the first conductive member 23. When the steering wheel cover 21 moves relative to the steering wheel base 11 away from the second conductive member 24, the metal dome recovers its deformation due to its own elastic force, transitions from the first state to the second state, and separates from the first conductive member 23.

[0081] Therefore, the second conductive member 24 is configured to include a metal spring, which facilitates the conversion of the second conductive member 24 between the first state and the second state and helps to simplify the structure of the second conductive member 24 .

[0082] In some embodiments, as Figure 4 and Figure 6 As shown, the metal spring includes an abutting portion 241, a first bent portion 242, and a second bent portion 243. The first bent portion 242 and the second bent portion 243 are provided on either side of the abutting portion 241 and are bent relative to the abutting portion 241 toward the steering wheel cover 21. The first bent portion 242 is connected to the steering wheel seat 11, and the second bent portion 243 is provided between the protruding portion 212 and the first conductive member 23. In the first state, the abutting portion 241 is in contact with and electrically connected to the first conductive member 23.

[0083] The bending angles of the first bending portion 242 and the second bending portion 243 relative to the abutment portion 241 and the extension distances of the first bending portion 242 and the second bending portion 243 can be set according to the position of the first conductive member 23, the position of the protrusion 212 and the position of the steering wheel seat 11, so as to achieve the purpose of the protrusion 212 driving the first conductive member 23 to switch between the first state and the second state.

[0084] The first bent portion 242 is connected to the steering wheel base 11. As the steering wheel cover 21 moves relative to the steering wheel base 11 toward the second conductive member 24, the protrusion 212 abuts against the second bent portion 243, driving the abutting portion 241 toward the first conductive member 23 and abutting against it. This further simplifies the structure of the electric steering wheel 10. The bent metal spring allows for greater deformation when subjected to force, improving the sensitivity of the first conductive member 23 in switching between the first and second states.

[0085] In some embodiments, as Figure 4 and Figure 5As shown, the first conductive member 23 is located on the side of the steering wheel base 11 away from the steering wheel cover 21 , and the second conductive member 24 is located between the steering wheel base 11 and the first conductive member 23 . In the first state, the protrusion 212 passes through the steering wheel base 11 and abuts against the second conductive member 24 .

[0086] As such, as the steering wheel cover 21 moves relative to the steering wheel base 11 toward the second conductive member 24, the protrusion 212 first abuts against the second conductive member 24, driving the second conductive member 24 toward the first conductive member 23 until the second conductive member 24 abuts against the first conductive member 23. In the second state, the protrusion 212 passes through the steering wheel base 11, which further simplifies the internal structure of the electric steering wheel 10 and improves the smoothness of the electric steering wheel 10 triggering the horn to sound.

[0087] In some embodiments, as Figure 2 and Figure 4 As shown, the steering wheel cover 21 includes a plurality of protrusions 212 , and the electric steering wheel 10 includes a plurality of second conductive members 24 . The protrusions 212 and the second conductive members 24 are arranged in a one-to-one correspondence.

[0088] The plurality of protrusions 212 may be arranged in a ring shape, or may be arranged in a rectangular shape or other arrangements.

[0089] The protrusions 212 and the second conductive members 24 are arranged in a one-to-one correspondence. Therefore, when the steering wheel cover 21 is pressed at a position corresponding to any one of the protrusions 212 and the steering wheel cover 21 is tilted, the corresponding protrusion 212 can still drive the corresponding second conductive member 24 to be converted from the second state to the first state. In this way, pressing multiple positions on the steering wheel cover 21 can trigger the horn to sound, which is beneficial to improving the sensitivity of the horn sounding mechanism to trigger the horn to sound.

[0090] In some embodiments, the first conductive member 23 is annular and disposed around the rotation axis of the steering wheel seat 11 , the plurality of protrusions 212 are disposed in an annular array, and the plurality of second conductive members 24 are disposed in an annular array.

[0091] Optionally, the plurality of protrusions 212 may be arranged in a ring shape and evenly spaced apart. Similarly, the plurality of second conductive members 24 may also be arranged in a ring shape and evenly spaced apart.

[0092] Since the first conductive member 23 is annular and is arranged around the rotation axis of the steering wheel seat 11, multiple protrusions 212 and multiple second conductive members 24 are arranged in an annular array, and any protrusion 212 can drive the corresponding second conductive member 24 to contact and electrically connect with the first conductive member 23.

[0093] In this way, by pressing multiple parts of the steering wheel cover 21 corresponding to the protrusion 212 along the circumference of the steering wheel cover 21, the second conductive member 24 can be driven by the protrusion 212 to contact and electrically connect with the annular first conductive member 23, which is beneficial to further improve the sensitivity of the electric steering wheel 10 to trigger the horn to sound.

[0094] In some embodiments, as Figure 3 and Figure 4 As shown, the protrusion 212 is columnar, and the elastic member 22 includes a spring, which is sleeved on the protrusion 212 .

[0095] In this way, during the process of the spring deforming or restoring its deformation, the protrusion 212 can provide a certain guiding effect for the deformation or restoration of the spring, which is beneficial to improving the smoothness of the movement of the steering wheel cover 21 relative to the steering wheel base 11 along the first direction X.

[0096] In some embodiments, as Figure 4 and Figure 5 As shown, the inner diameter of the spring gradually increases from the end of the spring facing the cover body 211 to the end facing the steering wheel seat 11 .

[0097] In this way, the spring can be a tower-type spring. During the movement of the steering wheel cover 21 along the first direction X toward the steering wheel seat 11, the structural stability of the spring is better, which is conducive to improving the smoothness of the movement of the steering wheel cover 21 along the first direction X and reducing the risk of twisting or bending of the spring. During the process of pressing the steering wheel cover 21, it is conducive to reducing the risk of abnormal noise inside the electric steering wheel 10.

[0098] Second, as Figure 1 and Figure 2 As shown, the vehicle 1 provided according to an embodiment of the present application includes the electric steering wheel 10 and the horn provided in any of the above embodiments, and the horn is electrically connected to the first conductive member 23.

[0099] The horn can be mounted on the body of vehicle 1, with one end of the horn electrically connected to the body. The horn can be electrically connected to the first conductive member 23 via a conductive structure. In a first state, the circuit loop for driving the horn to produce sound is closed, and the horn produces sound. In a second state, the circuit loop for driving the horn to produce sound is open, and the horn does not produce sound.

[0100] The vehicle 1 may be an engineering vehicle, a passenger car, a special vehicle, or the like.

[0101] The vehicle 1 provided in the embodiment of the present application has the same technical effect as that provided in any of the above embodiments because it adopts the electric steering wheel 10.

[0102] In some embodiments, the vehicle 1 is an agricultural machine.

[0103] For example, the vehicle 1 may be a tractor, a harvester, or a seed drill.

[0104] If the vehicle 1 is an agricultural machine, the electric steering wheel 10 can be applied to the agricultural machine, which is beneficial to simplifying the structure of the electric steering wheel 10 of the agricultural machine. Since the working environment of the agricultural machine is complex, the electric steering wheel 10 of the agricultural machine is easily subjected to loads such as impact or vibration. It is beneficial to reduce the risk of the electric steering wheel 10 of the agricultural machine generating abnormal noise under the action of loads such as vibration and impact.

[0105] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
