Description

Technical Field

[0001] This invention relates to the field of automotive steering wheel technology, and more particularly to a quick-folding multi-functional steering wheel. Background Technology

[0002] The steering wheel system provides steering commands for the car, as well as a mounting structure for airbags or horn covers, while also taking into account functions such as human-machine comfort.

[0003] In general, the steering wheel of a car remains fixed when not in use. When the driver is resting in the car, the fixed steering wheel occupies the space in the driver's cabin, and the steering wheel cannot be flipped or its position changed. With the rapid development of smart cockpits, the need for a rotating steering wheel to provide more space for the driver and the expansion of comfort functions have become new development requirements. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a quick-folding multi-function steering wheel to solve the problem that the steering wheel cannot be flipped or its position changed.

[0005] To achieve the above objectives, the present invention provides a quick-folding multi-functional steering wheel, including a hub and a rim. A first flipping mechanism is fixedly connected to the side of the hub near the rim, and a second flipping mechanism is fixedly connected to the rim near the first flipping mechanism. The first flipping mechanism and the second flipping mechanism are rotatably connected to each other to connect the hub and the rim.

[0006] Optionally, the first flipping mechanism includes a first fixed plate fixedly connected to the wheel hub, a first fixed disc fixedly connected to the side of the first fixed plate away from the wheel hub, a first limiting ring fixedly connected to the side of the first fixed disc away from the first fixed plate, a first fixed shaft rotatably connected to the first fixed disc at a position inside the first limiting ring, a ratchet fixedly connected to the first fixed shaft near the first limiting ring, and the first fixed shaft and the first limiting ring being connected by a first coil spring.

[0007] Optionally, the second flipping mechanism includes a second fixed plate fixedly connected to the wheel rim, a second fixed disc fixedly connected to the side of the second fixed plate away from the wheel rim, a second limiting ring fixedly connected to the side of the second fixed disc away from the second fixed plate, a second fixed shaft slidably connected through the second fixed disc within the second limiting ring, a limiting block slidably connected to the second fixed shaft near the second fixed disc, the limiting block and the second limiting ring being connected by a second coil spring, a pawl fixedly connected to the second fixed shaft near the ratchet, and a stop block fixedly connected to the second fixed shaft near the pawl.

[0008] Optionally, the other end of the first fixed shaft is fixedly connected to the second fixed disk.

[0009] Optionally, the ratchet and pawl engage.

[0010] Optionally, the second fixed shaft extends to the outside of the second fixed disc.

[0011] Optionally, the stop block is located on the side of the pawl near the limiting block.

[0012] Optionally, a return spring is sleeved on the second fixed shaft, one end of the return spring abutting against the limiting block, and the other end of the return spring abutting against the stop block.

[0013] Optionally, an extension structure may be detachably connected to the rim.

[0014] The beneficial effects of the present invention are as follows: By setting the first and second flipping mechanisms, the rim and hub of the steering wheel can rotate relative to each other. When manually rotated to the vertical position, it provides more space for the driver. When manually rotated to the horizontal position, the provided extension structure is placed on the rim, including but not limited to providing a cup holder, reading and writing platform, providing the driver with more comfortable and convenient functions. When not needed, the extension structure can be removed from the rim without hindering the normal use of the steering wheel. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] like Figures 1 to 9As shown, a quick-folding multi-function steering wheel includes a hub 1 and a rim 2. A first flipping mechanism 3 is fixedly connected to the side of the hub 1 near the rim 2, and a second flipping mechanism 4 is fixedly connected to the rim 2 near the first flipping mechanism 3. The first flipping mechanism 3 and the second flipping mechanism 4 are rotatably connected to each other to connect the hub 1 and the rim 2.

[0030] When the steering wheel needs to be flipped, rotate the rim 2 to a vertical position. The rotation of the rim 2 drives the second flipping mechanism 4 to rotate. At this time, the second flipping mechanism 4 rotates relative to the first flipping mechanism 3. The first flipping mechanism 3 locks the second flipping mechanism 4, keeping the rim 2 in a vertical position and increasing the space in the driver's seat. Similarly, rotate the rim 2 to a horizontal position. At this time, the provided extension structure 20 is placed on the rim 2, including but not limited to providing a cup holder, reading and writing platform, providing the driver with more comfortable and convenient functions. When not needed, the extension structure 20 can be removed from the rim 2 without interfering with the normal use of the steering wheel.

[0031] In one implementation, such as Figure 2 , Figure 4 and Figure 5 As shown, the first flipping mechanism 3 includes a first fixed plate 5 fixedly connected to the hub 1. A first fixed disk 6 is fixedly connected to the side of the first fixed plate 5 away from the hub 1. A first limiting ring 7 is fixedly connected to the side of the first fixed disk 6 away from the first fixed plate 5. A first fixed shaft 8 is rotatably connected to the first fixed disk 6 located inside the first limiting ring 7. A ratchet 9 is sleeved and fixedly connected to the first fixed shaft 8 near the first limiting ring 7. The first fixed shaft 8 and the first limiting ring 7 are connected by a first coil spring 10.

[0032] In one implementation, such as Figure 3 and Figure 6 As shown, the second flipping mechanism 4 includes a second fixed plate 11 fixedly connected to the wheel rim 2. A second fixed disk 12 is fixedly connected to the side of the second fixed plate 11 away from the wheel rim 2. A second limiting ring 13 is fixedly connected to the side of the second fixed disk 12 away from the second fixed plate 11. A second fixed shaft 14 is slidably connected through the second fixed disk 12 within the second limiting ring 13. A limiting block 15 is slidably connected to the second fixed shaft 14 near the second fixed disk 12. The limiting block 15 and the second limiting ring 13 are connected by a second coil spring 16. A pawl 17 is fixedly connected to the second fixed shaft 14 near the ratchet 9. A stop block 18 is fixedly connected to the second fixed shaft 14 near the pawl 17.

[0033] In one implementation, such as Figure 6As shown, the other end of the first fixed shaft 8 is fixedly connected to the second fixed disk 12.

[0034] Under the action of the return spring 19, the limiting block 15 abuts against the second fixed plate 12, and the other end of the return spring 19 abuts against the stop block 18, so that the stop block 18 abuts against the ratchet 9. At this time, the first coil spring 10 and the second coil spring 16 keep the pawl 17 engaged with the ratchet 9, and the steering wheel is in the initial state. When the steering wheel is flipped, the wheel rim 2 is manually rotated to a horizontal state. The rotation of the wheel rim 2 drives the second fixed plate 11 to rotate, the rotation of the second fixed plate 11 drives the second fixed plate 12 to rotate, the rotation of the second fixed plate 12 drives the first fixed shaft 8 to rotate, the rotation of the first fixed shaft 8 drives the ratchet 9 to rotate, and at the same time, the first coil spring 10 is tightened, and the second coil spring 16 makes the pawl 17 engage with the ratchet 9, thereby locking the ratchet 9 and keeping the wheel rim 2 in a horizontal position. In the horizontal position, when the steering wheel needs to be reset, pull the second fixed shaft 14. The movement of the second fixed shaft 14 causes the pawl 17 to disengage from the ratchet 9. At this time, the elastic potential energy of the first coil spring 10 is released, causing the ratchet 9 to rotate in the opposite direction. The rotation of the ratchet 9 causes the first fixed shaft 8 to rotate, which in turn causes the second fixed plate 12 to rotate. The rotation of the second fixed plate 12 causes the second fixed plate 11 to rotate, thereby resetting the steering wheel to its initial state. Pull the second fixed shaft 14 to disengage the pawl 17 from the ratchet 9. Manually rotate the wheel rim 2 to a vertical position. Release the second fixed shaft 14. Under the action of the reset spring 19, the pawl 17 and the ratchet 9 engage, keeping the wheel rim 2 in a vertical position. When the steering wheel needs to be reset, the process is the same as the above reset process.

[0035] In one implementation, such as Figure 7 As shown, the ratchet 9 and the pawl 17 engage, allowing the pawl 17 to lock the ratchet 9.

[0036] In one implementation, such as Figure 3 As shown, the second fixed shaft 14 extends to the outside of the second fixed disk 12, and the second fixed shaft 14 can be pulled to perform a reset operation when a reset is required.

[0037] In one implementation, such as Figure 7 As shown, the stop block 18 is located on the side of the pawl 17 near the limiting block 15. The stop block 18 ensures that the pawl 17 and the ratchet 9 can engage and will not disengage under the action of the return spring 19.

[0038] In one implementation, such as Figure 7As shown, a return spring 19 is sleeved on the second fixed shaft 14. One end of the return spring 19 abuts against the limiting block 15, and the other end of the return spring 19 abuts against the stop block 18. After the reset operation is performed, the return spring 19 drives the stop block 18 to move, so that the stop block 18 abuts against the ratchet 9, and at the same time the pawl 17 engages with the ratchet 9.

[0039] In one implementation, such as Figure 8 As shown, an extension structure 20 is detachably connected to the wheel rim 2. If the extension structure 20 is a table, it may include, but is not limited to, providing a platform for placing a water cup, reading and writing, providing the driver with more comfortable and convenient functions. When not needed, the extension structure 20 can be removed from the wheel rim 2 without interfering with the normal use of the steering wheel.
