Description

Technical Field

[0001] This invention relates to the field of vehicle engineering technology, and in particular to a steering wheel webbing spoke assembly, a steering wheel assembly, and a vehicle. Background Technology

[0002] In related technologies, steering wheels with webbing are constructed by setting a tensioning structure at one end of the decorative webbing. During assembly, one end of the webbing is first fixed, and then the tensioning structure is connected to the steering wheel using fasteners to taut the webbing. However, to ensure the webbing remains taut, its length is typically set to be exactly equal to or slightly less than the distance between the two fixed ends on the steering wheel. When connecting the tensioning structure to the steering wheel with fasteners, this results in a large angle between the central axis of the fastening hole on the tensioning structure and the central axis of the fixing hole on the steering wheel. This makes the fastener installation process difficult, requiring multiple adjustments and leading to low assembly efficiency. Furthermore, after multiple adjustments, there is a risk that the fixing hole may become worn larger, causing the fasteners to become loose and potentially fall off, resulting in poor structural reliability. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a steering wheel webbing spoke assembly that allows for a relatively long overall length of the decorative webbing, enabling the retractable bracket to be easily placed in a predetermined position on the steering wheel assembly, reducing the difficulty of the retractable bracket installation process, ensuring reliable fixation of the retractable bracket relative to the steering wheel assembly, and allowing the two ends of the decorative webbing to be easily installed onto the steering wheel assembly, thereby improving the installation efficiency and reliability of the steering wheel webbing spoke assembly.

[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The following description, with reference to the accompanying drawings, describes a steering wheel webbing spoke assembly 10 according to an embodiment of the present invention. The steering wheel webbing spoke assembly 10 can be applied to a steering wheel assembly 100. The two ends of the steering wheel webbing spoke assembly 10 are respectively connected to the steering wheel center disc 50 and the steering wheel outer rim 60. The middle portion of the steering wheel webbing spoke assembly 10 is exposed to increase the diversity of the spokes of the steering wheel assembly 100, meet the user's demand for a high visual experience of the steering wheel assembly 100, and meet the user's demand for different textures of multiple spokes.

[0039] Reference Figures 1-3 According to a first aspect of the present invention, a steering wheel webbing spoke assembly 10 includes: a decorative webbing 1 and a retractor 2. The decorative webbing 1 includes a decorative section 11 and a connecting section 12. There are two connecting sections 12, and the two connecting sections 12 are respectively connected to the two ends of the decorative section 11. At least one of the two connecting sections 12 is connected to the retractor 2. For example, there may be two retractors 2, and the two retractors 2 are respectively connected to the two connecting sections 12. For example, there may also be only one retractor 2, and only one connecting section 12 is connected to the retractor 2.

[0040] The retractor 2 includes a spool 21 and a retractor bracket 22. The spool 21 is rotatably mounted on the retractor bracket 22. For example, one axial end of the spool 21 can be connected to the retractor bracket 22, or both axial ends of the spool 21 can be connected to the retractor bracket 22. The connecting section 12 connected to the retractor 2 is a retracting section 13, which is connected to the spool 21. For example, the spool 21 can be injection molded onto the retracting section 13, and the spool 21 and the retracting section 13 can also be connected and fixed by fasteners 24.

[0041] The scroll 21 has a first rotation position and a second rotation position. In the first rotation position, a portion of the decorative section 11 is wound around the scroll 21. In the second rotation position, at least a portion of the decorative section 11 wound around the scroll 21 is extended.

[0042] In other words, the tension of the decorative section 11 when the spool 21 is in the first rotation position is greater than the tension of the decorative section 11 when the spool 21 is in the second rotation position. The retractor 2 can switch the spool 21 from the second rotation position to the first rotation position, wind the decorative section 11 around its outer periphery, tighten the decorative section 11, and make the decorative webbing 1 taut. The retractor 2 can also switch the spool 21 from the first rotation position to the second rotation position, stretch at least a portion of the decorative section 11 wound on the spool 21, stretch the decorative section 11, and make the decorative webbing 1 slack.

[0043] When installing the steering wheel webbing spoke assembly 10, one connecting segment 12 of the decorative webbing 1 can be connected to the spool 21 first. The spool 21 is then mounted on the winding bracket 22. The spool 21 is adjusted to the second rotation position, and the decorative webbing 1 is stretched so that it is in a slack state. Then, the other connecting segment 12 of the steering wheel webbing spoke assembly 10 is installed onto the steering wheel assembly 100. After that, by adjusting the winding device 2 to the first rotation position, part of the decorative segment 11 is wound up and the decorative segment 11 is tightened so that the decorative webbing 1 is in a taut state, thus completing the installation of the steering wheel webbing spoke assembly 10.

[0044] Since the decorative webbing 1 is in a slack state when the retractor 2 is installed, interference with the retractor 2 caused by the decorative webbing 1 being too short can be avoided. This allows the retractor bracket 22 to be placed more easily in the preset position of the steering wheel assembly 100, reducing the difficulty of the installation process of the retractor bracket 22. This allows the retractor bracket 22 to be reliably fixed relative to the steering wheel assembly 100, improving the installation efficiency of the steering wheel webbing spoke assembly 10 and improving the reliability of the steering wheel webbing spoke assembly 10.

[0045] Furthermore, by rotating the spool 21 to wind the decorative section 11 and tighten the decorative webbing 1 after the retractor 2 is installed and fixed, it is not necessary to set the installation position of the retractor 2 with high precision, nor is it necessary to set the cutting precision of the decorative webbing 1 with high precision. This allows the overall length of the decorative webbing 1 to be set longer, resulting in a higher tolerance for errors in the steering wheel webbing spoke assembly 10. This reduces the processing difficulty of the retractor 2, reduces the processing difficulty of the steering wheel assembly 100, reduces the production cost of the steering wheel webbing spoke assembly 10, and reduces the production cost of the steering wheel assembly 100.

[0046] According to the present invention, the steering wheel assembly 100 is connected to the decorative webbing 1 by means of a retractor 2. When installing the steering wheel webbing spoke assembly 10, one end of the steering wheel webbing spoke assembly 10 can be connected to the steering wheel assembly 100 first, the retractor 21 can be adjusted to the second rotation position, the decorative webbing 1 can be stretched so that the decorative webbing 1 is in a slack state, and then the other end of the steering wheel webbing spoke assembly 10 can be installed to the steering wheel assembly 100. After that, the retractor 21 can be adjusted to the first rotation position, a portion of the decorative section 11 can be wound up, and the retractor 21 can be tightened. The decorative section 11 is kept taut, which allows for a longer overall length of the decorative webbing 1. This makes it easier to place the retractable bracket 22 into the preset position on the steering wheel assembly 100, reducing the installation difficulty of the retractable bracket 22. This ensures that the retractable bracket 22 can be reliably fixed relative to the steering wheel assembly 100, and allows both ends of the decorative webbing 1 to be easily installed onto the steering wheel assembly 100. This improves the installation efficiency and reliability of the steering wheel webbing spoke assembly 10.

[0047] Reference Figure 4 and Figure 5 According to some embodiments of the present invention, a through hole 211 is provided on the outer peripheral surface of the spool 21. The through hole 211 penetrates the spool 21 radially. The end of the winding section 13 away from the decorative section 11 passes through the through hole 211, is folded back, and wraps around the outer peripheral surface of the spool 21. The end of the winding section 13 away from the decorative section 11 is connected to the decorative section 11. For example, the end of the winding section 13 away from the decorative section 11 can be sewn onto the decorative section 11 by a sewing process, or the end of the winding section 13 away from the decorative section 11 can be connected and fixed to the decorative section 11 by a heat fusion technique.

[0048] This allows the spool 21 to reliably rotate the winding section 13, ensuring that the spool 21 can reliably wind the decorative section 11 around its outer surface, thus improving the reliability of the steering wheel webbing spoke assembly 10. Furthermore, connecting the end of the winding section 13 furthest from the decorative section 11 to the decorative section 11 eliminates the need for fasteners 24 to connect the winding section 13 and the spool 21, reducing the production cost of the steering wheel webbing spoke assembly 10. Simultaneously, this also reduces the damage to the winding section 13 caused by fasteners, effectively lowering the risk of the winding section 13 cracking and detaching from the spool 21, thereby improving the reliability of the retractor 2 and the steering wheel webbing spoke assembly 10.

[0049] Reference Figure 5 In some embodiments of the present invention, the through hole 211 extends through one end of the spool 21 along its axial direction. This allows the winding section 13 to be folded and connected to the decorative section 11 first, and then a portion of the winding section 13 is inserted into the through hole 211 through its axial end, wrapping the portion of the winding section 13 around the outer circumferential surface of the spool 21. This reduces the difficulty of the connection process between the spool 21 and the winding section 13, making it easier to install the winding section 13 onto the spool 21 and improving the production efficiency of the steering wheel webbing spoke assembly 10.

[0050] Reference Figure 1 and Figure 3 In some embodiments of the present invention, the retractable bracket 22 includes two retractable sub-brackets 221, which are arranged opposite to each other and spaced apart along the axial direction of the retractor 21. Each retractable sub-bracket 221 has a mounting groove. Both ends of the retractor 21 extend beyond the edge of the retractable section 13, and the portions of the retractor 21 extending beyond the edge of the retractable section 13 are respectively engaged in the two mounting grooves. The opening of each mounting groove is opposite to the decorative section 11. For example, the retractable bracket 22 may also include a connecting plate 223, on which the retractable sub-brackets 221 are disposed. The connecting plate 223 is connected and fixed to the steering wheel center plate 50 by fasteners 24.

[0051] This allows the force on the roller 21 to be more balanced, so that the roller 21 can be reliably fixed relative to the winding bracket 22. This effectively avoids the risk of wrinkles in the decorative section 11 caused by the roller 21 tilting under force, and allows the roller 21 to reliably tighten the decorative section 11, so that the decorative section 11 can reliably remain flat.

[0052] Reference Figures 3-5In some embodiments of the present invention, the reel 21 includes a body section 212, a threaded section 213, and a stop portion 214. The winding section 13 is connected to the body section 212, the threaded section 213 is connected to one axial end of the body section 212, and the stop portion 214 is sleeved on the body section 212 and abuts against the winding bracket 22. For example, the body section 212 is provided with a through hole 211, and the stop portion 214 is located at intervals along the axial direction of the through hole 211.

[0053] The retractor 2 also includes a locking member 23, which has a threaded hole adapted to the threaded section 213, and the locking member 23 is sleeved on the threaded section 213. The locking member 23 abuts against the side of the retractor 22 opposite to the abutment portion 214. For example, the locking member 23 can be a nut.

[0054] For example, when the winding bracket 22 includes two winding sub-brackets 21, a stop portion 214 can be provided between the two winding sub-brackets 221, and the stop portion 214 abuts against one of the winding sub-brackets 221, while a locking member 23 is provided on the side of the corresponding winding sub-bracket 221 away from the stop portion 214. When the winding bracket 22 includes two winding sub-brackets 21, the stop portion 214 can be provided on the side other than the two winding brackets 221, and the stop portion 214 abuts against one of the winding brackets 221, while a locking member 23 is provided on the side of the other winding bracket 221 away from the stop portion 214. When the winding bracket 22 includes two winding sub-brackets 21, there can be two stop portions 214. The two stop portions 214 can be evenly disposed between the two winding sub-brackets 21, and the two stop portions 214 respectively stop against the two winding sub-brackets 221. The locking member 23 can be correspondingly disposed in two, and the corresponding locking member 23 and the stop portion 214 are respectively located on both sides of the corresponding winding sub-bracket 221.

[0055] When the decorative section 11 is tightened, the locking member 23 can be rotated toward the stop part 214 so that the stop part 214 and the locking member 23 clamp the winding bracket 22, fix the winding shaft 21 relative to the winding bracket 22, and fix the winding shaft 21 in the first rotation position. The structure is simple, easy to use, and the threaded connection is reliable.

[0056] Reference Figure 2 and Figure 3 According to some optional embodiments of the present invention, the steering wheel webbing spoke assembly 10 further includes a tension bracket 3 and a webbing tie rod 4. The tension bracket 3 includes two hook brackets 31, each of which has a slot, and the opening direction of each slot is opposite to the decorative section 11.

[0057] Two connecting sections 12 are respectively connected to the webbing pull rod 4 and the retractor 2. The connecting section 12 connected to the webbing pull rod 4 is a pull rod section 14, which defines a pull rod hole. For example, the pull rod section 14 can be folded back and its end away from the decorative section 11 can be connected to the decorative section 11 to define the pull rod hole. Specifically, the end of the pull rod section 14 away from the decorative section 11 can be sewn onto the decorative section 11 by a sewing process, or the end of the pull rod section 14 away from the decorative section 11 can be connected and fixed to the decorative section 11 by a heat fusion technique.

[0058] The webbing tie rod 4 passes through the tie rod hole, and both ends of the webbing tie rod 4 extend out of the tie rod hole. The portions of the webbing tie rod 4 extending out of the tie rod hole are respectively engaged in two slots. For example, the webbing tie rod 4 can be a pin.

[0059] When installing the steering wheel webbing spoke assembly 10, the tensioning bracket 3 can be installed in the preset position of the steering wheel assembly 100, the winding bracket 22 can be installed in the preset position of the steering wheel assembly 100, the webbing tie rod 4 can be inserted into the tie rod hole, the winding section 13 can be connected to the winding shaft 21, the shaft can be rotated to the second rotation position to extend the decorative section 11, then the webbing tie rod 4 can be inserted into the slot, the shaft can be connected to the winding bracket 22, and then the shaft can be rotated to the first rotation position to tighten the decorative section 11, thus completing the assembly of the steering wheel webbing spoke assembly 10.

[0060] By setting up a webbing rod 4 to tension the decorative webbing 1, and creating a slot on the hook bracket that matches the webbing rod 4, the overall structure between the webbing rod 4 and the hook bracket is relatively simple, facilitating the installation of the webbing rod 4 onto the hook bracket and improving the assembly efficiency of the steering wheel webbing spoke assembly 10. Furthermore, this reduces the number of retractors 2, lowering the production cost of the webbing rod 4 and thus reducing the overall production cost of the steering wheel webbing spoke assembly 10. By positioning the opening of the slot away from the decorative section 11, the webbing rod 4 can be prevented from detaching from the slot, improving the reliability of the steering wheel webbing spoke assembly 10.

[0061] Reference Figures 1-3 According to a second aspect embodiment of the present invention, a steering wheel assembly 100 includes: a steering wheel center disc 50, a steering wheel outer rim 60, and a steering wheel webbing spoke assembly 10. The steering wheel outer rim 60 surrounds the outer periphery of the steering wheel center disc 50 and is connected to the steering wheel center disc 50 via steering wheel spokes 70. The steering wheel outer rim 60 is the steering wheel webbing spoke assembly 10 according to the first aspect embodiment of the present invention. One end of the steering wheel webbing spoke assembly 10 is connected to the steering wheel center disc 50, and the other end of the steering wheel webbing spoke assembly 10 is connected to the steering wheel outer rim 60.

[0062] According to the present invention, by providing the above-mentioned steering wheel webbing spoke assembly 10, the installation process difficulty of the steering wheel assembly 100 can be reduced, the installation efficiency of the steering wheel assembly 100 can be improved, and the reliability of the steering wheel assembly 100 can be improved.

[0063] Reference Figures 1-3 According to some embodiments of the present invention, the steering wheel webbing spoke assembly 10 further includes a tension bracket 3 and a webbing tie rod 4. The tension bracket 3 includes two hook brackets 31, each of which has a slot. The opening direction of each slot is opposite to the decorative section 11.

[0064] The two connecting sections 12 are respectively connected to the webbing pull rod 4 and the winding device 2. The connecting section 12 connected to the webbing pull rod 4 is the pull rod section 14, which defines the pull rod hole. The webbing pull rod 4 passes through the pull rod hole, and both ends of the webbing pull rod 4 extend out of the pull rod hole. The parts of the webbing pull rod 4 that extend out of the pull rod hole are respectively locked in two slots.

[0065] The retractor 2 is connected to the steering wheel center disc 50, and the tensioning bracket 3 is connected to the steering wheel outer rim 60. For example, the steering wheel outer rim 60 may include a metal frame 61, a flexible filling layer, and an outer trim layer 62. The outer trim layer 62 covers the outer periphery of the metal frame 61, and the flexible filling layer fills the space between the metal frame 61 and the outer trim layer 62 to reduce friction between them, making the steering wheel outer rim 60 more comfortable to hold. The tensioning bracket 3 can be connected to the metal frame 61 to improve the reliability of the connection between the tensioning bracket 3 and the steering wheel outer rim 60, thereby improving the structural reliability of the steering wheel assembly 100.

[0066] Compared to the retractor 2, the tension bracket 3 has a simpler structure and can be set more compactly. By placing the tension bracket 3 on the outer rim 60 of the steering wheel and the retractor 2 on the center disc 50 of the steering wheel, the space occupied by the retractor 2 on the outer rim 60 of the steering wheel can be reduced. This allows the tension bracket 3 to occupy less space on the outer rim 60 of the steering wheel, and the outer diameter of the outer rim 60 of the steering wheel can be set within a preset range, thereby improving the overall performance of the steering wheel assembly 100.

[0067] Reference Figure 1According to some embodiments of the present invention, the steering wheel assembly 100 further includes an airbag 80, a placement area for the airbag 80 on the steering wheel center disc 50, and the connection point between the steering wheel webbing spoke assembly 10 and the steering wheel center disc 50 located outside the placement area of ​​the airbag 80. This avoids the retractor 2 interfering with the deployment of the airbag 80, ensuring reliable deployment of the airbag 80, and also prevents the retractor 2 from being ejected and causing injury to the user when the airbag 80 deploys, thereby improving the reliability and safety performance of the steering wheel assembly 100.
