Description
Steering wheel and vehicle Technical Field
[0001] The present invention relates to the technical field of automobiles, and in particular to a steering wheel and a vehicle. Background Art
[0002] With the continuous development of the economy and the increasing number of cars, cars have become a very common means of transportation. Drivers often need to honk their horns while driving. Drivers press the steering wheel to make separate horn triggers contact and trigger the horn to sound. However, when the driver presses the steering wheel, the horn triggers not only collide with each other but also contact the steering wheel frame, generating a loud noise that causes discomfort to the occupants in the car cabin.
[0003] Summary of the Invention
[0004] The invention provides a steering wheel and a vehicle.
[0005] The steering wheel of an embodiment of the present application includes a fixing member, an airbag bracket, a first conductive member and a second conductive member. The airbag bracket is movably arranged relative to the fixing member, the first conductive member is installed on the fixing member, and the second conductive member is installed on the airbag bracket. At least one of the first conductive member and the second conductive member is elastic, and the second conductive member can contact the first conductive member as the airbag bracket moves relative to the fixing member to trigger the horn to operate.
[0006] The steering wheel of the embodiment of the present application contacts the second conductive part through the first conductive part. Since at least one of the first conductive part and the second conductive part is elastic, the first conductive part or the second conductive part can absorb the impact formed by the contact between the first conductive part and the second conductive part, thereby reducing the noise generated by the impact and improving the comfort of the passengers in the cabin.
[0007] In some embodiments, the first conductive member is elastic and has a filamentous structure; or the second conductive member is elastic and has a filamentous structure.
[0008] In this way, the elastic conductive member can absorb the impact caused by the contact between the first conductive member and the second conductive member, reducing the noise generated by the impact. At the same time, the conductive member with a filamentous structure reduces the contact area between the first conductive member and the second conductive member, thereby reducing the impact sound between the first conductive member and the second conductive member.
[0009] In some embodiments, the first conductive member is embedded in the fixing member.
[0010] In this way, the first conductive member is embedded in the fixing member so that the first conductive member and the fixing member form an integrated structure, which facilitates the disassembly and assembly of the first conductive member and the fixing member, and increases the convenience of steering wheel maintenance.
[0011] In some embodiments, the fixing member includes a mounting shaft and a connecting portion connected to the mounting shaft, the first conductive member is mounted on the connecting portion, the mounting shaft is formed with a center hole, the airbag bracket is at least partially disposed in the center hole, and moves relative to the fixing member along the axial direction of the mounting shaft.
[0012] In this way, the airbag bracket can move relative to the fixing member along the axial direction of the installation shaft, thereby driving the second conductive member to move relative to the first conductive member.
[0013] In some embodiments, the airbag bracket includes a main body and a mounting portion connected to the main body, the mounting portion is at least partially movably disposed in the center hole and is clamped with the bottom end of the mounting shaft, and the second conductive member is mounted on the main body.
[0014] In this way, the mounting portion can move relative to the fixing member along the axial direction of the mounting axis in the central hole, thereby driving the airbag bracket to move relative to the fixing member, so that the second conductive member moves relative to the first conductive member.
[0015] In some embodiments, the mounting portion includes at least two hooks, which are arranged along the circumference of the mounting shaft. The hook includes an elastic arm and a block. The elastic arm is connected to the main body, and the block is connected to one end of the elastic arm away from the main body. The block is engaged with the bottom end of the mounting shaft.
[0016] In this way, the hook can connect the mounting shaft and the main body, so that the relative distance between the first conductive member and the second conductive member is maintained within a certain range, reducing the distance and time the second conductive member moves relative to the first conductive member, thereby improving the efficiency of the speaker.
[0017] In some embodiments, the second conductive member includes a conductive portion and at least one protrusion disposed on the conductive portion, wherein the protrusion is configured to contact the first conductive member.
[0018] Thus, the contact between the protrusion and the first conductive member can reduce the contact area between the first conductive member and the second conductive member, thereby reducing the sound of the collision between the first conductive member and the second conductive member. In addition, at least one protrusion can improve the contact efficiency between the first conductive member and the second conductive member.
[0019] In certain embodiments, the steering wheel includes a first elastic member connecting the main body portion and the connecting portion.
[0020] In this way, the first elastic member can absorb the impact on the connecting portion caused by the movement of the main body relative to the fixing member, thereby reducing the vibration generated when the first conductive member contacts the second conductive member.
[0021] In some embodiments, the first elastic member is sleeved on the mounting shaft.
[0022] In this way, the first elastic member can move along the axial direction of the installation shaft, thereby making the first conductive member contact or separate from the second conductive member.
[0023] In some embodiments, the steering wheel includes a frame, and the fixing member is mounted on the frame.
[0024] In this way, the fixing member can be fixed on the steering wheel through the frame.
[0025] In some embodiments, there are multiple fixing members, and the multiple fixing members are spaced apart and distributed at different positions of the skeleton.
[0026] In this way, the plurality of fixing members can stably fix the first conductive member on the frame.
[0027] In some embodiments, a second elastic member is provided between the fixing member and the frame.
[0028] In this way, the second elastic member can absorb the impact on the frame caused by the second conductive member moving relative to the fixing member, thereby preventing the frame from being damaged by the impact for a long time, thereby increasing the service life of the steering wheel and improving the user experience.
[0029] The vehicle according to the embodiment of the present application includes a vehicle body and a steering wheel, and the steering wheel is arranged inside the vehicle body.
[0030] The vehicle of the embodiment of the present application is provided with a steering wheel, which is arranged inside the vehicle body. A first conductive member, a second conductive member and a fixed member are arranged inside the steering wheel. At least one of the first conductive member and the second conductive member is elastic. When the second conductive member moves close to and contacts the first conductive member, the first conductive member or the second conductive member can absorb the impact of the second conductive member on the fixed member during the movement of the second conductive member relative to the fixed member, thereby reducing the noise generated by the impact and improving the comfort of the occupants in the cabin.

[0048] Please refer to Figures 1 and 2. The steering wheel 100 of the embodiment of the present application includes a fixing member 10, an airbag bracket 20, a first conductive member 30 and a second conductive member 40. The airbag bracket 20 is movably arranged relative to the fixing member 10. The first conductive member 30 is installed on the fixing member 10, and the second conductive member 40 is installed on the airbag bracket 20. At least one of the first conductive member 30 and the second conductive member 40 is elastic. The second conductive member 40 can contact the first conductive member 30 as the airbag bracket 20 moves relative to the fixing member 10 to trigger the horn to work.
[0049] The steering wheel 100 of the embodiment of the present application contacts the second conductive member 40 through the first conductive member 30. Since at least one of the first conductive member 30 and the second conductive member 40 is elastic, the first conductive member 30 or the second conductive member 40 can absorb the impact formed by the contact between the first conductive member 30 and the second conductive member 40, thereby reducing the noise generated by the impact and improving the comfort of the occupants in the cabin.
[0050] Specifically, the fixing member 10 is used to fix the first conductive member 30. The fixing member 10 can be made of plastic material. The fixing member 10 is located on the side of the first conductive member 30 away from the second conductive member 40. The first conductive member 30 and the fixing member 10 can be integrally formed or fixed by mechanical connection.
[0051] The airbag bracket 20 is used to install the airbag. The airbag bracket 20 can be integrally injection molded with a plastic material. The airbag bracket 20 is located on the side of the second conductive member 40 away from the first conductive member 30. A groove can be formed on the side of the airbag bracket 20 close to the first conductive member 30, and the second conductive member 40 can be engaged in the groove.
[0052] The first conductive member 30 and the second conductive member 40 can be made of conductive materials such as conductive plastic, conductive rubber, and conductive metal. Either the first conductive member 30 or the second conductive member 40 can be elastic, or both can be elastic. The contact between the first conductive member 30 and the second conductive member 40 forms a closed circuit, triggering the speaker.
[0053] In some embodiments, the first conductive member 30 is elastic and has a filamentous structure; or the second conductive member 40 is elastic and has a filamentous structure.
[0054] In this way, the elastic conductive member can absorb the impact caused by the contact between the first conductive member 30 and the second conductive member 40, reducing the noise generated by the impact. At the same time, the conductive member with a filamentous structure reduces the contact area between the first conductive member 30 and the second conductive member 40, thereby reducing the impact sound between the first conductive member 30 and the second conductive member 40.
[0055] Specifically, the first conductive member 30 or the second conductive member 40 can be an element that is conductive, elastic, and filamentous. The first conductive member 30 or the second conductive member 40 includes, but is not limited to, a conductive spring. When the first conductive member 30 and the second conductive member 40 come into contact, the conductive spring is compressed and accumulates force. When the first conductive member 30 and the second conductive member 40 separate, the conductive spring returns to its original state.
[0056] Referring to FIG. 3 , in some embodiments, the first conductive member 30 is embedded in the fixing member 10 .
[0057] In this way, the first conductive member 30 is embedded in the fixing member 10 so that the first conductive member 30 and the fixing member 10 form an integrated structure, which facilitates the disassembly and assembly of the first conductive member 30 and the fixing member 10 and increases the convenience of maintenance of the steering wheel 100.
[0058] Specifically, the first conductive member 30 can be installed in the fixing member 10 using an insert injection molding process. The fixing member 10 is made of plastic material, and the first conductive member 30 is made of metal material. Insert injection molding is a process in which the first conductive member 30 is pre-fixed in an appropriate position in an injection mold, and then plastic is injected to form the mold. After the mold is opened, the first conductive member 30 is tightly wrapped by the cooled and solidified plastic and buried in the plastic to obtain a product with the first conductive member 30.
[0059] Referring to Figures 3 and 4, in some embodiments, the fixing member 10 includes a mounting shaft 11 and a connecting portion 12 connected to the mounting shaft 11, the first conductive member 30 is mounted on the connecting portion 12, the mounting shaft 11 is formed with a center hole 13, the airbag bracket 20 is at least partially disposed in the center hole 13, and moves relative to the fixing member 10 along the axial direction of the mounting shaft 11.
[0060] In this way, the airbag bracket 20 can move relative to the fixing member 10 along the axial direction of the installation axis 11 , thereby driving the second conductive member 40 to move relative to the first conductive member 30 .
[0061] Specifically, the mounting shaft 11 and the connecting portion 12 can be integrally formed or mechanically connected, such as by bolts. The first conductive member 30 can be embedded in the connecting portion 12 using an insert molding process. A center hole 13, such as a square or circular hole, is formed in the center of the mounting shaft 11. The center hole 13 extends axially through the mounting shaft 11, allowing the airbag holder 20 to move axially within the mounting shaft 11 through the center hole 13.
[0062] Please refer to Figures 3 and 4. In some embodiments, the airbag bracket 20 includes a main body 21 and a mounting portion 22 connected to the main body 21. The mounting portion 22 is at least partially movably disposed in the center hole 13 and is clamped with the bottom end of the mounting shaft 11. The second conductive member 40 is installed on the main body 21.
[0063] In this way, the mounting portion 22 can move relative to the fixing member 10 along the axial direction of the mounting axis 11 in the central hole 13 , thereby driving the airbag bracket 20 to move relative to the fixing member 10 and causing the second conductive member 40 to move relative to the first conductive member 30 .
[0064] Specifically, the main body 21 and the mounting portion 22 can be integrally formed or mechanically connected. The main body 21 can be square or circular in shape. A square or circular opening 211 is provided on the top surface of the main body 21. The opening 211 extends axially from the main body 21 toward the fixing member 10 to form a receiving space 212. The receiving space 212 can accommodate the airbag. The main body 21 extends axially from the bottom of the receiving space 212 toward the fixing member 10. A groove is formed at one end of the main body 21 near the fixing member 10, and the second conductive member 40 is disposed within the groove. The mounting portion 22 is disposed at the end of the main body 21 near the fixing member 10. One end of the mounting portion 22 is connected to the main body 21, and the other end is engaged with the mounting shaft 11. The mounting portion 22 can be solid or hollow. The outer diameter of the mounting portion 22 is equal to or slightly smaller than the inner diameter of the center hole 13, so that the mounting portion 22 can move axially within the center hole 13. The bottom of the mounting portion 22 extends outward along the circumference of the mounting portion 22 so that the mounting portion 22 can be engaged with the bottom surface of the mounting shaft 11 .
[0065] Please refer to Figure 4. In some embodiments, the mounting portion 22 includes at least two hooks 23, and the at least two hooks 23 are arranged along the circumference of the mounting shaft 11. The hook 23 includes an elastic arm 24 and a block 25. The elastic arm 24 is connected to the main body 21, and the block 25 is connected to the end of the elastic arm 24 away from the main body 21. The block 25 is engaged with the bottom end of the mounting shaft 11.
[0066] In this way, the hook 23 can connect the mounting shaft 11 and the main body 21, so that the relative distance between the first conductive member 30 and the second conductive member 40 is maintained within a certain range, reducing the distance and time for the second conductive member 40 to move relative to the first conductive member 30, thereby improving the efficiency of the speaker.
[0067] Specifically, the number of hooks 23 can be two, three, four, five, or the like, with the hooks 23 evenly distributed along the circumference of the mounting shaft 11. The elastic arm 24 can be elongated, connecting the block 25 and the main body 21. The elastic arm 24 can be an elastic element, such as rubber. The block 25 extends from one end of the elastic arm 24 away from the main body 21 toward the side closer to the mounting shaft 11. The top surface of the block 25 abuts the bottom surface of the mounting shaft 11. The block 25 can be made of a plastic material. When the airbag holder 20 moves toward the fixing member 10, the mounting portion 22 and the mounting shaft 11 approach each other, at which point the block 25 engages with the bottom of the mounting shaft 11, compressing the elastic arm 24 and accumulating force. When the airbag holder 20 moves away from the fixing member 10, the mounting portion 22 and the mounting shaft 11 move away from each other, at which point the block 25 engages with the bottom of the mounting shaft 11, and the elastic arm 24 returns to its original state, resetting the airbag holder 20.
[0068] Referring to FIG. 5-FIG . 7 , in some embodiments, the second conductive member 40 includes a conductive portion 41 and at least one protrusion 42 disposed on the conductive portion 41 . The protrusion 42 is configured to contact the first conductive member 30 .
[0069] In this way, the contact between the protrusion 42 and the first conductive member 30 can reduce the contact area between the first conductive member 30 and the second conductive member 40, thereby reducing the sound of the collision between the first conductive member 30 and the second conductive member 40. In addition, at least one protrusion 42 can improve the contact efficiency between the first conductive member 30 and the second conductive member 40.
[0070] Specifically, the conductive portion 41 can be a sheet-like structure, the conductive portion 41 can be distributed in a straight line or a curved line, the conductive portion 41 can be open, and the two ends of the conductive portion 41 are not connected. The shape of the protrusion 42 can be circular or square, and the protrusion 42 is provided on the side of the conductive portion 41 close to the first conductive member 30, and the protrusion 42 extends along the bottom surface of the conductive portion 41 close to the first conductive member 30. The number of protrusions 42 can be two, three, four, etc. For example, the number of protrusions 42 is four, and the four protrusions 42 can be symmetrically distributed along the conductive portion 41. When one of the protrusions 42 fails, the other three protrusions 42 can still contact the first conductive member 30. When the first conductive member 30 is a filamentous structure, the contact between the protrusion 42 and the first conductive member 30 is point-to-surface contact. The smaller the bottom surface area of the protrusion 42, the smaller the contact area between the first conductive member 30 and the second conductive member 40.
[0071] Referring to FIG. 3 and FIG. 4 , in some embodiments, the steering wheel 100 includes a first elastic member 50 , and the first elastic member 50 connects the main body 21 and the connecting portion 12 .
[0072] In this way, the first elastic member 50 can absorb the impact on the connecting portion 12 caused by the movement of the main body 21 relative to the fixing member 10 , thereby reducing the vibration generated when the first conductive member 30 and the second conductive member 40 contact each other.
[0073] Specifically, the first elastic member 50 can be an elastic element, including but not limited to a spring, a rubber sleeve, etc. When the airbag bracket 20 moves toward the fixing member 10, the main body 21 moves relative to the fixing member 10, gradually approaching the connecting portion 12. The first elastic member 50, located between the main body 21 and the connecting portion 12, can cushion the impact of the main body 21 on the connecting portion 12, thereby reducing the impact transmitted to the first conductive member 30 and reducing the vibration generated when the first conductive member 30 contacts the second conductive member 40.
[0074] Referring to FIG. 4 , in some embodiments, the first elastic member 50 is sleeved on the mounting shaft 11 .
[0075] In this way, the first elastic member 50 can move along the axial direction of the installation shaft 11 , thereby making the first conductive member 30 contact or separate from the second conductive member 40 .
[0076] Specifically, the first elastic member 50 may be an elastic element having a through hole 51 at its center, including but not limited to a spring. The mounting shaft 11 may be disposed in the through hole 51 of the first elastic member 50 .
[0077] Referring to FIG. 1 , in some embodiments, a steering wheel 100 includes a frame 60 , and a fixing member 10 is mounted on the frame 60 .
[0078] In this way, the fixing member 10 can be fixed to the steering wheel 100 through the frame 60 .
[0079] Specifically, the frame 60 of the steering wheel 100 may include a main body 61 and a connecting section 62. The main body 61 may be an annular portion of the frame 60, and the connecting section 62 may be connected to the main body 61 along the diameter of the ring. The connecting section 62 may have a straight connection structure or a curved connection structure. For example, a side view of the frame 60 composed of the main body 61 and the connecting section 62 may resemble a trapezoid. The airbag bracket 20 is snap-fitted and fixed to the middle portion of the main body 61, and the fixing member 10 is mounted on the connecting section 62 parallel to the plane of the main body 61.
[0080] Please refer to FIG. 1 and FIG. 8 . In some embodiments, there are multiple fixing members 10 , and the multiple fixing members 10 are spaced apart and distributed at different positions of the frame 60 .
[0081] In this way, the plurality of fixing members 10 can stably fix the first conductive member 30 on the frame 60 .
[0082] Specifically, the number of fixing parts 10 can be two, three, four, etc. For example, if the number of fixing parts 10 is two, the two fixing parts 10 can be symmetrically distributed along the skeleton 60 to balance the force on the first conductive part 30 and improve the stability of the first conductive part 30 on the skeleton 60.
[0083] Referring to FIG. 1 and FIG. 2 , in some embodiments, a second elastic member 70 is disposed between the fixing member 10 and the frame 60 .
[0084] In this way, the second elastic member 70 can absorb the impact on the skeleton 60 caused by the second conductive member 40 moving relative to the fixing member 10, preventing the skeleton 60 from being damaged by the impact for a long time, thereby increasing the service life of the steering wheel 100 and improving the user experience.
[0085] Specifically, the second elastic member 70 can be an elastic element, including but not limited to a spring, rubber, etc. When the airbag bracket 20 moves toward the fixing member 10, the main body 21 moves relative to the fixing member 10, gradually approaching the connecting portion 12. The second elastic member 70, located between the fixing member 10 and the frame 60, can cushion the impact of the main body 21 on the connecting portion 12, thereby reducing the impact transmitted to the first conductive member 30 and reducing the vibration generated when the first conductive member 30 and the second conductive member 40 come into contact.
[0086] For example, taking the user pressing the steering wheel 100 as an example, when the user presses the steering wheel 100, the airbag bracket 20 in the steering wheel 100 will press the second conductive part 40 to move axially along the mounting axis 11, and the second conductive part 40 will push the first elastic part 50 to move until the protrusion 42 on the second conductive part 40 contacts the first conductive part 30. The first conductive part 30 is elastic and can buffer the impact formed by the contact between the first conductive part 30 and the second conductive part 40. At the same time, the first elastic part 50 can also absorb part of the impact force generated when the airbag bracket 20 moves relative to the skeleton 60. The second elastic part 70 can absorb part of the impact force from the fixing part 10, thereby reducing the impact transmitted to the skeleton 60.
[0087] In addition, the structural assembly method related to the first conductive member 30 and the second conductive member 40 can be as follows: first, the second conductive member 40 is installed in the groove of the airbag bracket 20, the first conductive member 30 is insert-molded in the fixing member 10, and then the first elastic member 50 is sleeved on the mounting shaft 11, and finally the fixing member 10 is clipped onto the mounting portion 22 of the airbag bracket 20.
[0088] Referring to FIG. 9 , a vehicle 1000 according to an embodiment of the present application includes a vehicle body 200 and a steering wheel 100 , wherein the steering wheel 100 is disposed within the vehicle body 200 .
[0089] The vehicle 1000 of the embodiment of the present application is provided with a steering wheel 100, which is arranged in the vehicle body 200.
