[0042] In a first aspect, as shown in FIG. 1, FIG. 2 and FIG. 3, the electric steering wheel 10 provided by the embodiments of the present application comprises a steering wheel seat 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 comprises a motor shell 121 and an output shaft 122, the output shaft 122 is connected with the steering wheel seat 11 and is configured to drive the steering wheel seat 11 to rotate. The steering wheel cover 21 covers the steering wheel seat 11 and can move along a first direction X relative to the steering wheel seat 11. The elastic member 22 is arranged between the steering wheel seat 11 and the steering wheel cover 21. The first conductive member 23 is arranged on the motor shell 121 and is insulated from the motor shell 121, and the first conductive member 23 is configured to be electrically connected with a horn. The second conductive member 24 is electrically connected with the motor shell 121, and along the first direction X, the second conductive member 24 is arranged between the steering wheel cover 21 and the first conductive member 23. 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 is in contact with and electrically connected with the first conductive member 23. In the second state, the second conductive member 24 is separated from the first conductive member 23.

[0043] The electric steering wheel 10 can be configured in a vehicle 1 and mounted on a steering wheel support in the vehicle 1. The motor 12 comprises a motor shell 121 and an output shaft 122, the output shaft 122 can be connected with the steering wheel seat 11 through a bearing or other structure. According to the real-time situation of the environment during the operation of the vehicle 1, the motor 12 is controlled by a related control module in the vehicle 1 to drive the steering wheel seat 11 and the steering wheel cover 21 to rotate together, and the angle of rotation of the steering wheel seat 11 and the steering wheel cover 21 is controlled according to the control signal of the control module, so as to realize the automatic driving function of the vehicle 1.

[0044] The steering wheel cover 21 is covered on the steering wheel seat 11 and can move along the first direction X relative to the steering wheel seat 11, so that the steering wheel cover 21 and the steering wheel seat 11 can be connected by clamping, and the steering wheel cover 21 has a degree of freedom relative to the steering wheel seat 11 along the first direction X.

[0045] The elastic member 22 is arranged between the steering wheel seat 11 and the steering wheel cover 21. During pressing the steering wheel cover 21, the steering wheel cover 21 is displaced relative to the steering wheel seat 11 along the first direction X towards the second conductive member 24, and the elastic member 22 is deformed. 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 be displaced relative to the steering wheel seat 11 along the first direction X away from the second conductive member 24. Optionally, the elastic member 22 can be a spring or the like.

[0046] The first conductive member 23 can be a metal member and is arranged on the motor housing 121 and insulated from the motor housing 121, so that the motor housing 121 provides support for the first conductive member 23. In the second state, the first conductive member 23 is not in electrical connection with the motor housing 121, so that the horn does not sound.

[0047] The first conductive member 23 is configured to be electrically connected with the horn, and the horn can be arranged on the vehicle body of the vehicle 1, so that the first conductive member 23 can be electrically connected with the horn through a conductive structure or the like.

[0048] The second conductive member 24 is electrically connected with the motor housing 121. Optionally, the second conductive member 24 can be directly in contact with and electrically connected with the motor housing 121, or the second conductive member 24 can be electrically connected with the motor housing 121 through a conductive structure. The second conductive member 24 is electrically connected with the motor housing 121, and since the motor housing 121 is electrically connected with the vehicle body of the vehicle 1, the second conductive member 24 is electrically connected with the vehicle body in the first state and the second state, and further electrically connected with the horn.

[0049] The steering wheel cover 21 can drive the second conductive member 24 to switch between the first state and the second state. The steering wheel cover 21 can move relative to the steering wheel seat 11 under an external force and drive the second conductive member 24 to switch between the first state and the second state.

[0050] The transition between the first state and the second state of the second conductive member 24 can be a change in shape of the second conductive member 24. For example, the second conductive member 24 can be elastic, and the steering wheel cover 21 can drive the second conductive member 24 to produce elastic deformation, so as to realize the transition between the first state and the second state of the second conductive member 24. Alternatively, the transition 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 can drive the second conductive member 24 to produce displacement in the first direction X, so as to realize the transition between the first state and the second state of the second conductive member 24. Of course, the transition 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. The specific setting can be made according to actual needs.

[0051] It can be understood that, in the absence of an external force 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. During the pressing of the steering wheel cover 21, the steering wheel cover 21 moves towards the second conductive member 24 in the first direction X and applies a force to the second conductive member 24, so as to make the second conductive member 24 transition from the second state to the first state and be in contact and electrically connected with the first conductive member 23.

[0052] Since the second conductive member 24 is electrically connected with the motor housing 121, the first conductive member 23 is configured to be electrically connected with the horn of the vehicle 1. The motor housing 121 can be electrically connected with the vehicle body of the vehicle 1, and the horn is electrically connected with the vehicle body and the first conductive member 23. Thus, in the case where the first conductive member 23 and the second conductive member 24 are in contact and electrically connected, a circuit configured to drive the horn to sound forms a closed loop, so as to drive the horn to sound. That is, in the case where the second conductive member 24 is in the first state, the horn of the vehicle 1 can sound.

[0053] After the external force applied to the steering wheel cover 21 is removed, the steering wheel cover 21 moves away from the second conductive member 24 in the first direction X, and the second conductive member 24 transitions from the first state to the second state. The second conductive member 24 is separated from the first conductive member 23, and the circuit configured to drive the horn to sound is disconnected, so the horn no longer sounds. That is, in the case where the second conductive member 24 is in the second state, the horn of the vehicle 1 does not sound.

[0054] The first conductive member 23 can have various shapes, and the electric power steering 10 can include one, two or more first conductive members 23. Each of the first conductive members 23 can be in contact and electrically connected with the second conductive member 24, so as to trigger the horn to sound.

[0055] Optionally, the electric steering wheel 10 can be provided with one or more second conductive members 24, which can be arranged in an annular array so that any one of the second conductive members 24 is in contact with and electrically connected to the first conductive member 23, and can trigger the horn to sound.

[0056] The first conductive member 23 is arranged in the motor housing 121 and is insulatedly connected to the motor housing 121. By replacing the plurality of conductive wires with the first conductive member 23, the wire harness arrangement inside the electric steering wheel 10 is facilitated to be simplified, thereby simplifying the internal structure of the electric steering wheel 10, facilitating the assembly and maintenance of the electric steering wheel 10, and reducing the risk of abnormal sound inside the electric steering wheel 10.

[0057] Therefore, the electric steering wheel 10 provided by the embodiments of the present application can trigger the horn to sound or not by arranging the first conductive member 23 in the motor housing 121 and insulatingly connecting it to the motor housing 121, and arranging the second conductive member 24 to be switchable between the first state and the second state. Arranging the first conductive member 23 in the motor housing 121 facilitates the simplification of the wire harness arrangement inside the electric steering wheel 10, reduces the risk of abnormal sound of the electric steering wheel 10 under the action of vibration or impact load, and simplifies the internal structure of the electric steering wheel 10, facilitating the assembly and maintenance of the electric steering wheel 10.

[0058] In some embodiments, as shown in FIG. 2, the first conductive member 23 is annular and surrounds the rotation axis of the steering wheel base 11.

[0059] In this way, one first conductive member 23 can be opposite to a plurality of second conductive members 24 along the first direction X, and any one of the second conductive members 24 can be switched to the first state under the drive of the steering wheel cover 21, and can trigger the horn to sound. This facilitates the further simplification of the internal structure of the electric steering wheel 10 and improves the sensitivity of the electric steering wheel 10 to trigger the horn to sound.

[0060] In some embodiments, as shown in FIG. 5, the motor 12 includes a connector 123 arranged on the motor housing 121 and configured to be electrically connected to the horn, and the first conductive member 23 is electrically connected to the connector 123.

[0061] The first conductive member 23 is electrically connected to the connector 123. Optionally, the first conductive member 23 can be directly connected to the connector 123, or the first conductive member 23 can be electrically connected to the connector 123 through an intermediate conductive structure.

[0062] The connector 123 can be a structure such as a jack, which is electrically connected to the first conductive member 23 and configured to be electrically connected to the horn. In this way, the convenience of electrically connecting the first conductive member 23 to the horn is improved, and the structure and process of electrically connecting the first conductive member 23 to the horn are simplified.

[0063] In some embodiments, as shown in FIG. 5, the electric steering wheel 10 further comprises a wire 14, which electrically connects the first conductive part 23 and the connector 123.

[0064] Optionally, the wire 14 can be arranged inside the motor 12, or the wire 14 can be arranged outside the motor 12.

[0065] By arranging the wire 14, the convenience of connecting the first conductive part 23 and the connector 123 is improved, and the positions of the connector 123 or the first conductive part 23 can be flexibly arranged as needed.

[0066] In some embodiments, as shown in FIGS. 2, 3, 4 and 6, the electric steering wheel 10 further comprises an insulating part 13, the first conductive part 23 comprises a conductive body 231 and a conductive contact part 232, the conductive body 231 is annular and arranged around the rotation axis of the steering wheel base 11, the conductive contact part 232 is arranged protruding away from the second conductive part 24 relative to the conductive body 231, and is in contact with and electrically connected to the wire 14, and the insulating part 13 is arranged between the conductive body 231 and the motor housing 121.

[0067] The conductive contact part 232 can be electrically connected to the horn through the wire 14, for example, one end of the wire 14 is welded to the conductive contact part 232, and the other end is configured to be electrically connected to the horn.

[0068] The conductive contact part 232 is arranged protruding away from the second conductive part 24 relative to the conductive body 231, which facilitates the electrical connection of the conductive contact part 232 and the horn, and in the first state, the second conductive part 24 can be in contact with and electrically connected to the conductive body 231.

[0069] The insulating part 13 is arranged between the conductive body 231 and the motor housing 121, so as to realize the insulation of the first conductive part 23 and the motor housing 121 through the insulating part 13, and reduce the risk of electrical connection between the first conductive part 23 and the motor housing 121.

[0070] Therefore, such an arrangement facilitates reducing the risk of electrical connection between the first conductive part 23 and the motor housing 121 while realizing the electrical connection between the first conductive part 23 and the horn.

[0071] In some embodiments, as shown in FIGS. 2 and 3, the steering wheel cover 21 comprises a cover body 211 and a protruding part 212, the protruding part 212 is arranged protruding towards the steering wheel base 11 relative to the cover body 211 along the first direction X, and at least part of the second conductive part 24 is arranged between the protruding part 212 and the first conductive part 23 along the first direction X.

[0072] Optionally, the protruding part 212 can be block-shaped, column-shaped or other shapes.

[0073] Thus, in the process that the steering wheel cover 21 moves relative to the steering wheel base 11 along the first direction X towards the second conductive part 24, the protruding part 212 pushes the second conductive part 24 to move to convert from the second state to the first state, which is conducive to simplifying the structure of the steering wheel cover 21 and reducing the weight of the steering wheel cover 21.

[0074] In some embodiments, as shown in FIG. 4 and FIG. 6, the second conductive part 24 is provided in a cantilevered manner, one end of the second conductive part 24 is connected to the steering wheel base 11, and the other end is a free end 24a and is arranged between the protruding part 212 and the first conductive part 23. In the first state, the protruding part 212 is configured to abut against the free end 24a to enable the second conductive part 24 to contact the first conductive part 23.

[0075] One end of the second conductive part 24 is connected to the steering wheel base 11 to realize electrical connection with the motor housing 121 through the steering wheel base 11, and further realize electrical connection with the vehicle body of the vehicle 1. The second conductive part 24 is provided in a cantilevered manner, one end of the second conductive part 24 is a free end 24a, and the protruding part 212 is configured to abut against the free end 24a to enable the second conductive part 24 to contact the first conductive part 23. Since the second conductive part 24 is provided in a cantilevered manner, the free end 24a can produce a larger deformation under the abutment of the protruding part 212, which is conducive to realizing the contact and electrical connection between the second conductive part 24 and the first conductive part 23.

[0076] Therefore, the second conductive part 24 and the first conductive part 23 are electrically connected, and the structure of the second conductive part 24 is simplified.

[0077] In some embodiments, the second conductive part 24 includes a metal spring.

[0078] It can be understood that in the case that the electric steering wheel 10 has a plurality of second conductive parts 24, all the second conductive parts 24 can be provided as metal springs, or a part of the second conductive parts 24 can be provided as metal springs, which can be selected according to actual needs.

[0079] The metal spring has a certain elasticity. Thus, in the process that the steering wheel cover 21 moves relative to the steering wheel base 11 towards the second conductive part 24, the metal spring deforms and is pushed by the protruding part 212 towards the first conductive part 23, the metal spring converts from the second state to the first state and is electrically connected with the first conductive part 23. In the process that the steering wheel cover 21 moves relative to the steering wheel base 11 away from the second conductive part 24, the metal spring restores the deformation under the action of its own elasticity, converts from the first state to the second state, and is separated from the first conductive part 23.

[0080] Therefore, the second conductive member 24 is provided with the metal spring sheet, so that the conversion of the second conductive member 24 between the first state and the second state is facilitated, and the structure of the second conductive member 24 is simplified.

[0081] In some embodiments, as shown in FIGS. 4 and 6, the metal spring sheet includes an abutting portion 241, a first bending portion 242 and a second bending portion 243, the first bending portion 242 and the second bending portion 243 are arranged on both sides of the abutting portion 241 and are bent towards the steering wheel cover 21 relative to the abutting portion 241. The first bending portion 242 is connected with the steering wheel base 11, and the second bending portion 243 is arranged 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 with the first conductive member 23.

[0082] According to the positions of the first conductive member 23, the protruding portion 212 and the steering wheel base 11, the bending angles of the first bending portion 242 and the second bending portion 243 relative to the abutting portion 241 and the extension distances of the first bending portion 242 and the second bending portion 243 can be set, so as to facilitate the purpose of driving the first conductive member 23 to convert between the first state and the second state by the protruding portion 212.

[0083] The first bending portion 242 is connected with the steering wheel base 11. During the movement of the steering wheel cover 21 towards the second conductive member 24 relative to the steering wheel base 11, the protruding portion 212 abuts against the second bending portion 243, driving the abutting portion 241 to move towards the first conductive member 23 and abutting against the first conductive member 23. In this way, the mechanism of the electric power steering wheel 10 is further simplified. The metal spring sheet can produce greater deformation under stress by being bent, which is conducive to improving the sensitivity of the first conductive member 23 in converting between the first state and the second state.

[0084] In some embodiments, as shown in FIGS. 4 and 5, 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 protruding portion 212 passes through the steering wheel base 11 and abuts against the second conductive member 24.

[0085] In this way, during the movement of the steering wheel cover 21 towards the second conductive member 24 relative to the steering wheel base 11, the protruding portion 212 first abuts against the second conductive member 24 and drives the second conductive member 24 to move towards the first conductive member 23 until the second conductive member 24 abuts against the first conductive member 23. In the second state, the protruding portion 212 passes through the steering wheel base 11. In this way, the mechanism inside the electric power steering wheel 10 is further simplified, and the smoothness of the electric power steering wheel 10 in triggering the horn to sound is improved.

[0086] In some embodiments, as shown in FIG. 2 and FIG. 4, the steering wheel cover 21 comprises a plurality of protrusions 212, and the electric steering wheel 10 comprises a plurality of second conductive members 24, the protrusions 212 are arranged one-to-one corresponding to the second conductive members 24.

[0087] The plurality of protrusions 212 can be arranged in a ring shape, or the plurality of protrusions 212 can be arranged in a rectangular shape or other shapes.

[0088] The protrusions 212 are arranged one-to-one corresponding to the second conductive members 24, so that in the case that the steering wheel cover 21 is inclined at any position corresponding to the protrusions 212, the corresponding protrusions 212 can still drive the corresponding second conductive members 24 to switch from the second state to the first state, so that the horn sound can be triggered by pressing multiple positions on the steering wheel cover 21, which is beneficial to improve the sensitivity of the horn sound triggering mechanism.

[0089] In some embodiments, the first conductive member 23 is annular and surrounds the rotation axis of the steering wheel base 11, the plurality of protrusions 212 are arranged in a ring shape, and the plurality of second conductive members 24 are arranged in a ring shape.

[0090] Alternatively, the plurality of protrusions 212 can be arranged in a ring shape and uniformly spaced, and the plurality of second conductive members 24 can also be arranged in a ring shape and uniformly spaced.

[0091] Since the first conductive member 23 is annular and surrounds the rotation axis of the steering wheel base 11, the plurality of protrusions 212 and the plurality of second conductive members 24 are arranged in a ring shape, so that any protrusion 212 can drive the corresponding second conductive member 24 to contact and electrically connect with the first conductive member 23.

[0092] In this way, along the circumference of the steering wheel cover 21, pressing multiple positions on the steering wheel cover 21 corresponding to the protrusions 212 can drive the second conductive members 24 to contact and electrically connect with the annular first conductive member 23 through the protrusions 212, which is beneficial to further improve the sensitivity of the electric steering wheel 10 triggering the horn sound.

[0093] In some embodiments, as shown in FIG. 3 and FIG. 4, the protrusions 212 are columnar, and the elastic member 22 comprises a spring, and the spring is sleeved on the protrusions 212.

[0094] In this way, the protrusions 212 can provide a certain guiding effect for the deformation or recovery of the spring during the deformation or recovery of the spring, which is beneficial to improve the smoothness of the steering wheel cover 21 moving relative to the steering wheel base 11 along the first direction X.

[0095] In some embodiments, as shown in FIG. 4 and FIG. 5, the inner diameter of the spring gradually increases from one end of the cover body 211 towards the steering wheel base 11.

[0096] In this way, the spring can be a tower spring, and the structural stability of the spring is better during movement of the steering wheel cover 21 towards the steering wheel base 11 along the first direction X, which is conducive to improving the smoothness of movement of the steering wheel cover 21 along the first direction X and reducing the risk of distortion or bending of the spring. During pressing of the steering wheel cover 21, it is conducive to reducing the risk of abnormal noise in the electric steering wheel 10.

[0097] In the second aspect, as shown in FIG. 1 and FIG. 2, the vehicle 1 provided by the embodiments of the present application includes the electric steering wheel 10 provided by any of the above embodiments and a horn, and the horn is electrically connected with the first conductive part 23.

[0098] The horn can be mounted on the vehicle body of the vehicle 1, and one end of the horn can be electrically connected with the vehicle body. The horn and the first conductive part 23 can be electrically connected through a conductive structure. In the first state, the circuit loop configured to drive the horn to sound is in a closed state, and the horn sounds. In the second state, the circuit loop configured to drive the horn to sound is in an open state, and the horn does not sound.

[0099] The vehicle 1 can be an engineering vehicle, a passenger vehicle, or a special vehicle, etc.

[0100] The vehicle 1 provided by the embodiments of the present application has the same technical effects as the electric steering wheel 10 provided by any of the above embodiments.

[0101] In some embodiments, the vehicle 1 is an agricultural machine.

[0102] For example, the vehicle 1 can be a tractor, a harvester, or a seeder, etc.

[0103] When the vehicle 1 is an agricultural machine, the electric steering wheel 10 can be applied to the agricultural machine, which is conducive 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 impact or vibration loads, which is conducive to reducing the risk of abnormal noise of the electric steering wheel 10 of the agricultural machine under the action of vibration, impact, etc.

[0104] Although the present application has been described with reference to the preferred embodiments, various modifications can be made to it without departing from the scope of the present application, and equivalent components can be substituted therefor. In particular, the technical features mentioned in each embodiment can be combined in any way as long as there is no structural conflict. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims. Industrial applicability

[0105] In summary, the application provides an electric steering wheel and a vehicle, which are beneficial to simplify the structure in the electric steering wheel and reduce the risk of abnormal sound generated by the electric steering wheel.
