Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Hereinafter, with reference to the accompanying drawings, a steering wheel 100 according to an embodiment of the present invention will be described.

[0023] like Figures 1-11 As shown, the steering wheel 100 according to an embodiment of the present invention includes: a first rim 1 and a second rim 2. The first rim 1 includes a first functional element 11. The second rim 2 is rotatably connected to the first rim 1 to switch between an unfolded state and a folded state. The second rim 2 includes a second functional element 21. In the unfolded state, the first functional element 11 and the second functional element 21 are electrically connected to conduct, and in the folded state, the first functional element 11 and the second functional element 21 are disconnected.

[0024] For example, refer to Figures 1-5 As shown, the steering wheel 100 includes a first rim 1 and a second rim 2. The first rim 1 can be the upper rim and the second rim 2 can be the lower rim. The first rim 1 includes a first frame, a first foam component, and a first functional component 11. The first foam component covers the first frame, and the first functional component 11 covers the outside of the first foam component. The first functional component 11 can be configured to realize hands-free detection (HOD), heating function, or other functions.

[0025] The first ring 1 is also provided with a power supply interface 14 and a switch. The first functional component 11 is connected to the power supply connector. The power supply interface 14 is electrically connected to the power supply component through the switch. The switch is used to selectively conduct the power supply interface 14 and the power supply component so that the power supply component can supply power to the first functional component 11 through the power supply interface 14.

[0026] The second wheel rim 2 is rotatably connected to the first wheel rim 1 so that the steering wheel 100 can switch between an unfolded state and a folded state. The second wheel rim 2 includes a second frame, a second foam component, and a second functional component 21. The second foam component covers the second frame, and the second functional component 21 covers the outside of the second foam component. The second functional component 21 can be configured to realize a hands-free detection function, a heating function, or other functions.

[0027] In the unfolded state, the first functional component 11 and the second functional component 21 are electrically connected to conduct electricity, and in the folded state, the first functional component 11 and the second functional component 21 are disconnected. Of course, the second functional component 21 can also be connected to a power supply interface 14, which will not be elaborated here.

[0028] Specifically, the vehicle has a manual driving mode and an intelligent driving mode. When the vehicle is in manual driving mode, the steering wheel 100 can be switched to the unfolded state, and the driver can hold the steering wheel 100 to control the vehicle. At this time, the first functional component 11 and the second functional component 21 are electrically connected to achieve conduction, and the first functional component 11 and the second functional component 21 form a circuit so that the first functional component 11 and the second functional component 21 can work together to achieve preset functions, such as heating function or hands-free detection function. When the vehicle is in intelligent driving mode, the steering wheel 100 can be switched to the folded state, and the driver can take both hands off the steering wheel 100 and control the vehicle by the intelligent driving system. At this time, the circuit between the first functional component 11 and the second functional component 21 is broken, so that the first functional component 11 and the second functional component 21 stop working.

[0029] With the above settings, the arrangement of the first functional component 11 and the second functional component 21 is not restricted by the folding structure, which can reduce the design difficulty of the steering wheel 100 and help meet the functional design requirements.

[0030] According to the present invention, the steering wheel 100 can be made conductive in the unfolded state and disconnected in the folded state by setting the first functional component 11 and the second functional component 21. This allows the arrangement of the first functional component 11 and the second functional component 21 to be unrestricted by the folding structure, which can reduce the design difficulty of the steering wheel 100, help meet the functional design requirements of the steering wheel 100, and improve the practicality of the steering wheel 100.

[0031] In some embodiments of the present invention, the first functional component 11 is connected to the first conductive part 12, and the second functional component 21 is connected to the second conductive part 22. In the unfolded state, the first conductive part 12 and the second conductive part 22 cooperate to make the first functional component 11 and the second functional component 21 conductive. In the folded state, the first conductive part 12 and the second conductive part 22 separate to make the first functional component 11 and the second functional component 21 disconnected.

[0032] For example, refer to Figures 3-5 As shown, the side of the first wheel rim 1 facing the second wheel rim 2 can be designated as the first mating surface 1a, and the side of the second wheel rim 2 facing the first wheel rim 1 can be designated as the second mating surface 2a. When the steering wheel 100 is switched to the unfolded state, the first mating surface 1a and the second mating surface 2a come into contact and engage.

[0033] The first functional component 11 is connected to a first conductive part 12, which is located on a first mating surface 1a. The second functional component 21 is connected to a second conductive part 22, which is located on a second mating surface 2a. In the unfolded state, the first mating surface 1a and the second mating surface 2a are in contact and engaged, so that the first conductive part 12 and the second conductive part 22 engage to make the first functional component 11 and the second functional component 21 conductive. In the folded state, the first mating surface 1a and the second mating surface 2a are disengaged, so that the first conductive part 12 and the second conductive part 22 are separated to make the first functional component 11 and the second functional component 21 disconnected.

[0034] The above settings make the switching on and off of the first functional component 11 and the second functional component 21 more convenient and smooth, which helps to reduce the failure rate of the steering wheel 100, and also simplifies the structure of the steering wheel 100, which helps to reduce costs and improves the design rationality of the steering wheel 100.

[0035] In some embodiments of the present invention, such as Figures 4-6 As shown, the first conductive part 12 includes a first contact 121, and the second conductive part 22 includes a second contact 221. In the unfolded state, the first contact 121 and the second contact 221 engage to connect the first functional component 11 and the second functional component 21. This simplifies the structure of the steering wheel 100, reduces its cost, lowers its failure rate, and improves its practicality.

[0036] In some embodiments of the present invention, the first conductive part 12 further includes a first terminal 123 and a first elastic member. The first terminal 123 is electrically connected to the first functional member 11, and the first contact 121 is elastically connected to the first terminal 123 through the first elastic member.

[0037] For example, refer to Figure 6As shown, the first conductive part 12 further includes a first terminal 123, a first elastic member, and a first housing 122. A first receiving cavity is formed within the first housing 122. At least a portion of the first contact 121, at least a portion of the first terminal 123, and the first elastic member are all received within the first receiving cavity. The first terminal 123 is electrically connected to the first functional member 11, and the first contact 121 is elastically connected to the first terminal 123 via the first elastic member. Thus, when the steering wheel 100 is switched to the unfolded state, the first contact 121 can contact the second contact 221 to compress the first elastic member. The compressed first elastic member can apply an elastic force to the first contact 121, so that the first contact 121 can elastically press against the second contact 221. It should be noted that the first elastic member can be a spring or a conductive elastomer.

[0038] With the above settings, the first contact 121 and the second contact 221 can be stably engaged, which helps to improve the stability of the first functional component 11 and the second functional component 21 when conducting, and improves the reliability of the steering wheel 100.

[0039] In some embodiments of the present invention, the second conductive part 22 further includes a second terminal 223 and a second elastic member. The second terminal 223 is electrically connected to the second functional member 21, and the second contact 221 is elastically connected to the second terminal 223 through the second elastic member.

[0040] For example, refer to Figure 6 As shown, the second conductive part 22 further includes a second terminal 223, a second elastic member, and a second housing 222. A second receiving cavity is formed within the second housing 222. At least a portion of the second contact 221, at least a portion of the second terminal 223, and the second elastic member are all accommodated within the second receiving cavity. The second terminal 223 is electrically connected to the second functional member 21, and the second contact 221 is elastically connected to the second terminal 223 via the second elastic member. Thus, when the steering wheel 100 is switched to the unfolded state, the second contact 221 can contact the first contact 121 to compress the second elastic member. The compressed second elastic member can apply an elastic force to the second contact 221, allowing the second contact 221 to elastically press against the first contact 121. It should be noted that the second elastic member can be a spring or a conductive elastomer.

[0041] The above settings enable the first contact 121 and the second contact 221 to cooperate stably, which helps to improve the stability of the first functional component 11 and the second functional component 21 when they are connected, and improves the reliability of the steering wheel 100.

[0042] In some embodiments of the present invention, such as Figure 6As shown, one of the first contact 121 and the second contact 221 can be constructed as a recessed contact, and the other can be constructed as a protruding contact. This increases the mating area between the first contact 121 and the second contact 221, which helps improve the communication stability between the first functional component 11 and the second functional component 21.

[0043] In some embodiments of the present invention, the materials of the first contact 121 and the second contact 221 can be one or more of beryllium copper, nickel, tin, silver, gold, etc. This ensures the conductivity of the first contact 121 and the second contact 221.

[0044] In some embodiments of the present invention, such as Figures 4-5 As shown, the first functional component 11 includes a plurality of first functional wires 111, all of which are connected to the first conductive part 12. The second functional component 21 includes a plurality of second functional wires 211, all of which are connected to the second conductive part 22. In the unfolded state, the first conductive part 12 and the second conductive part 22 cooperate to make the first functional wires 111 and the second functional wires 211 conduct. The first functional wires 111 and the second functional wires 211 can form a loop, thereby enabling the first functional component 11 and the second functional component 21 to work together.

[0045] It is understandable that by setting the first functional component 11 to include multiple first functional wires 111 and setting the second functional component 21 to include multiple second functional wires 211, the multiple first functional wires 111 and the multiple second functional wires 211 can work together to optimize the performance of the steering wheel 100, such as improving the heating efficiency of the steering wheel 100, improving the heating uniformity of the steering wheel 100, or improving the accuracy of the hands-off detection, thereby improving the practicality of the steering wheel 100.

[0046] In some embodiments of the present invention, there are multiple sets of first functional wires 111, each set of first functional wires 111 is connected to a first conductive part 12, and there are multiple sets of second functional wires 211, each set of second functional wires 211 is connected to a second conductive part 22. In the unfolded state, the multiple first conductive parts 12 and the multiple second conductive parts 22 are matched one-to-one.

[0047] For example, refer to Figures 7-9 As shown, the first functional wires 111 can be set into multiple groups, each group having several first functional wires 111, such as one, two or more (multiple first functional wires 111 in the same group can be set in parallel), and each group of first functional wires 111 is connected to the first conductive part 12.

[0048] Meanwhile, the second functional wires 211 can be set into multiple groups, each group having several second functional wires 211, such as one, two or more (multiple second functional wires 211 in the same group can be set in parallel), and each group of second functional wires 211 is connected to a second conductive part 22.

[0049] In the unfolded state, multiple first conductive parts 12 and multiple second conductive parts 22 are matched one-to-one so that a set of first functional wires 111 can be electrically connected to a corresponding set of second functional wires 211 to form an independent circuit.

[0050] With the above settings, when individual first functional wires 111 or second functional wires 211 fail to conduct, the first functional component 11 and the second functional component 21 can still work normally, achieving redundant design and improving the reliability of the steering wheel 100.

[0051] In some embodiments of the present invention, at least some of the first functional wires 111 have different functions, and at least some of the second functional wires 211 have different functions.

[0052] For example, a portion of the plurality of first functional wires 111 may be set as heating resistance wires, and another portion of the plurality of first functional wires 111 may be set as HOD capacitor wires; a portion of the plurality of second functional wires 211 may be set as heating resistance wires, and another portion of the plurality of second functional wires 211 may be set as HOD capacitor wires.

[0053] With the above settings, the first functional component 11 and the second functional component 21 can perform multiple functions, which helps to meet the functional design requirements of the steering wheel 100 and improves the practicality of the steering wheel 100.

[0054] In some embodiments of the present invention, the plurality of first functional wires 111 include at least one of HOD capacitor wires and heating resistance wires. For example, all of the plurality of first functional wires 111 may be HOD capacitor wires; or, all of the plurality of first functional wires 111 may be heating resistance wires; or, a portion of the plurality of first functional wires 111 may be heating resistance wires, and another portion of the plurality of first functional wires 111 may be HOD capacitor wires. This facilitates meeting different design requirements.

[0055] In some embodiments of the present invention, the plurality of second functional wires 211 include at least one of HOD capacitor wires and heating resistance wires. For example, all of the plurality of second functional wires 211 may be HOD capacitor wires; or, all of the plurality of second functional wires 211 may be heating resistance wires; or, a portion of the plurality of second functional wires 211 may be heating resistance wires, and another portion of the plurality of second functional wires 211 may be HOD capacitor wires. This facilitates meeting different design requirements.

[0056] In some embodiments of the present invention, such as Figures 10-11 As shown, the first wheel rim 1 is provided with a first positioning component 13, which is located on the first mating surface 1a. The second wheel rim 2 is provided with a second positioning component 23, which is located on the second mating surface 2a. In the unfolded state, the first positioning component 13 and the second positioning component 23 are positioned and engaged. This improves the fitting accuracy between the first wheel rim 1 and the second wheel rim 2, ensuring smooth communication between the first functional component 11 and the second functional component 21 in the unfolded state, thus improving the reliability of the steering wheel 100.

[0057] In some embodiments of the present invention, a first functional component 11 is connected to a first conductive portion 12, and a second functional component 21 is connected to a second conductive portion 22. In the unfolded state, the first conductive portion 12 and the second conductive portion 22 cooperate to make the first functional component 11 and the second functional component 21 conductive. In the folded state, the first conductive portion 12 and the second conductive portion 22 separate to make the first functional component 11 and the second functional component 21 disconnected. The first positioning component 13 includes a first positioning portion 131, which is spaced apart from the first conductive portion 12. The second positioning component 23 includes a second positioning portion 231, which is spaced apart from the second conductive portion 22. In the unfolded state, the first positioning portion 131 and the second positioning portion 231 are positioned and engaged.

[0058] For example, refer to Figures 10-11 As shown, the first functional component 11 is connected to the first conductive part 12, which is located on the first mating surface 1a. The second functional component 21 is connected to the second conductive part 22, which is located on the second mating surface 2a. In the unfolded state, the first mating surface 1a and the second mating surface 2a are in contact and engaged, so that the first conductive part 12 and the second conductive part 22 are engaged, thereby enabling the first functional component 11 and the second functional component 21 to conduct electricity. In the folded state, the first mating surface 1a and the second mating surface 2a are disengaged, so that the first conductive part 12 and the second conductive part 22 are separated, thereby enabling the first functional component 11 and the second functional component 21 to disconnect.

[0059] The first positioning component 13 includes a first positioning part 131, which is spaced apart from the first conductive part 12. The second positioning component 23 includes a second positioning part 231, which is spaced apart from the second conductive part 22. In the unfolded state, the first positioning part 131 and the second positioning part 231 are positioned and cooperated.

[0060] Specifically, the first positioning part 131 can be constructed as a positioning protrusion, and the second positioning part 231 can be constructed as a positioning groove, with the protrusion height of the first positioning part 131 matching the depth of the second positioning part 231 so that the first positioning part 131 can be completely accommodated within the second positioning part 231; or, the first positioning part 131 can be constructed as a positioning groove, and the second positioning part 231 can be constructed as a positioning protrusion, with the protrusion height of the second positioning part 231 matching the depth of the first positioning part 131 so that the second positioning part 231 can be completely accommodated within the first positioning part 131.

[0061] The above settings can improve the fitting accuracy between the first wheel rim 1 and the second wheel rim 2, so as to ensure that the first functional component 11 and the second functional component 21 can be smoothly connected in the unfolded state, thereby improving the reliability of the steering wheel 100.

[0062] In some embodiments of the present invention, such as Figures 10-11 As shown, multiple first positioning parts 131 can be provided, with the multiple first positioning parts 131 arranged at intervals, and multiple second positioning parts 231 can be provided, with the multiple first positioning parts 131 arranged at intervals, and the multiple second positioning parts 231 correspond one-to-one with the multiple first positioning parts 131 and cooperate. This improves the fitting accuracy between the first wheel rim 1 and the second wheel rim 2.

[0063] In some embodiments of the present invention, such as Figures 10-11 As shown, the first positioning component 13 further includes a third positioning part 132, and a first guiding part 12 is disposed on the third positioning part 132. The second positioning component 23 further includes a fourth positioning part 232, and a second guiding part 22 is disposed on the fourth positioning part 232. In the unfolded state, the third positioning part 132 and the fourth positioning part 232 are positioned and cooperated.

[0064] Specifically, the third positioning part 132 can be configured as a positioning protrusion, and the fourth positioning part 232 can be configured as a positioning groove, with the protrusion height of the third positioning part 132 matching the depth of the fourth positioning part 232 so that the third positioning part 132 can be completely accommodated within the fourth positioning part 232; or, the third positioning part 132 can be configured as a positioning groove, and the fourth positioning part 232 can be configured as a positioning protrusion, with the protrusion height of the fourth positioning part 232 matching the depth of the third positioning part 132 so that the fourth positioning part 232 can be completely accommodated within the third positioning part 132.

[0065] By setting the above, the matching accuracy of the first conductive part 12 and the second conductive part 22 can be optimized in a targeted manner to ensure that the first functional component 11 and the second functional component 21 can be stably connected in the unfolded state, thereby improving the reliability of the steering wheel 100.

[0066] Specifically, when the vehicle switches from intelligent driving mode to manual driving mode, the second wheel rim 2 flips downward relative to the first wheel rim 1, and the first positioning part 131 and the second positioning part 231 first come into contact and fit together to ensure that the first wheel rim 1 and the second wheel rim 2 can be aligned; as the second wheel rim 2 continues to flip, the third positioning part 132 and the fourth positioning part 232 gradually fit together. At this time, the first guiding part 12 and the second guiding part 22 gradually come into contact until the second wheel rim 2 is fully unfolded, and the steering wheel 100 switches to the unfolded state.
