Detailed Implementation
[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0046] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0047] As described in the background section, when the seams of the steering wheel cover in the related technology are exposed to external foreign objects or static electricity, these objects and static electricity can easily reach the electrical components inside the steering wheel cover through the seams, causing the steering wheel function to be affected or even malfunction, resulting in poor reliability of the steering wheel in the related technology.
[0048] To address the poor reliability of steering wheels in the aforementioned related technologies, embodiments of this application provide a steering wheel cover. By providing a blocking structure at the inner end of the seam of the steering wheel cover, foreign objects and static electricity are blocked, eliminating or mitigating the negative impact of foreign objects and static electricity on the electrical components inside the steering wheel cover, thereby improving the reliability of the steering wheel. Embodiments of this application also provide a steering wheel including the aforementioned steering wheel cover.
[0049] Figure 1 This is a schematic diagram of the steering wheel from a first-view perspective in one embodiment of this application; Figure 2 This is a schematic diagram of the steering wheel from a second perspective in one embodiment of this application; Figure 3 This is a schematic diagram of the steering wheel frame 2 in one embodiment of this application. Figures 1 to 3 As shown, the steering wheel provided in this embodiment includes a steering wheel frame 2 and a steering wheel cover 1. The steering wheel frame 2 includes a rim 21 and a transmission part 22 connected to the rim 21. The steering wheel cover 1 covers the outer side of the rim 21. Optionally, the rim 21 extends around the rotation axis of the steering wheel to form a closed structure. For example, the rim 21 is an approximately circular structure. The two ends of the transmission part 22 are connected to the inner side of the rim 21, and the rotation axis of the steering wheel passes through the transmission part 22. In other embodiments, the shape of the rim 21 can be rectangular or approximately rectangular; the rim 21 can also be a non-closed structure (i.e., not surrounding the axis of the steering wheel 360°). The steering wheel frame 2 can be made of a high-strength material, such as an alloy; to ensure its stability, the steering wheel frame 2 can be a one-piece structure.
[0050] Optionally, the shape of the steering wheel cover 1 is adapted to the shape of the wheel rim 21 so that the steering wheel cover 1 can compactly and snugly cover the wheel rim 21. The steering wheel cover 1 includes multiple housings, which are joined together to form a cavity for covering the wheel rim 21. Seams are formed between adjacent housings. Figure 1 and Figure 2 As shown, optionally, the plurality of housings include a first housing 11 and a second housing 12, the first housing 11 and the second housing 12 being detachably spliced in a predetermined direction to form a splicing assembly 10 having a receiving cavity, the receiving cavity being used to receive at least a portion of the rim 21.
[0051] The steering wheel cover 1 may include multiple assembly components 10, which are sequentially connected in the circumferential direction of the steering wheel to form a closed structure. It can be understood that the multiple cavities formed by the multiple assembly components 10 together constitute the cavity of the steering wheel cover 1. Figure 1 , Figure 2 In the illustrated embodiment, the steering wheel cover 1 includes four assembly components 10, each of which includes a first housing 11 and a second housing 12. Therefore, the steering wheel cover 1 is formed by the jointing of eight housings to create a cavity that accommodates the wheel rim 21. It should be understood that in other alternative embodiments, the number of assembly components 10 can be increased or decreased as needed; even in some embodiments, the steering wheel cover 1 may include only one assembly component 10, for example, the annular first housing 11 and the annular second housing 12 are joined in the direction extending along the steering wheel rotation axis to cover the wheel rim 21.
[0052] In this embodiment, the first housing 11 and the second housing 12 are arranged in a predetermined direction, and their openings are joined together to form a receiving cavity. Optionally, the predetermined direction is parallel to the rotation axis of the steering wheel, that is, one of the first housing 11 and the second housing 12 is located on the front of the steering wheel, and the other is located on the back of the steering wheel. In other possible embodiments, the predetermined direction may also be perpendicular to the rotation axis of the steering wheel, that is, the first housing 11 and the second housing 12 are arranged radially on the steering wheel, one is located on the inner side of the rim 21 (towards the transmission part 22), and the other is located on the outer side of the rim 21.
[0053] In this embodiment, the seam has an inner end near the cavity and an outer end away from the cavity in its depth direction. A blocking structure connected to the housing is provided inside the steering wheel cover 1, and the blocking structure blocks at least part of the inner end of the seam. By providing the blocking structure, foreign objects and static electricity entering the steering wheel cover 1 from the seam can be effectively blocked, preventing foreign objects and static electricity from directly reaching the electrical components inside the steering wheel cover 1, or mitigating the diffusion of foreign objects inside the steering wheel cover 1, reducing the risk of steering wheel malfunction, and improving steering wheel reliability.
[0054] In this embodiment, the seams of the steering wheel cover 1 include a first seam 101 and a second seam 102; wherein, the first seam 101 is formed at the joint between the first housing 11 and the second housing 12 in the same assembly 10, and the second seam 102 is formed between the joint ends of two adjacent assemblies 10. The width of the seams (including the first seam 101 and the second seam 102) should be as small as possible to reduce the probability of foreign objects entering the steering wheel cover 1 through the seams. Optionally, the width of the seams is 0 to 2 mm.
[0055] Optionally, the blocking structure inside the steering wheel cover 1 includes a first blocking structure and / or a second blocking structure, wherein the first blocking structure is used to block at least part of the inner end of the first seam 101, and the second blocking structure is used to block at least part of the inner end of the second seam 102.
[0056] Figure 4 for Figure 1 A sectional view along direction A. (e.g.) Figure 4 As shown, the first housing 11 has a first splicing edge, and the second housing 12 has a second splicing edge. The first splicing edge and the second splicing edge are spliced together to form a first seam 101. Figure 4 In this embodiment, the first housing 11 and the second housing 12 have C-shaped cross-sections, with two first splicing edges located at the two ends of the C-shaped cross-section of the first housing 11, and two second splicing edges located at the two ends of the C-shaped cross-section of the second housing 12. In this embodiment, the inner ends of the two first seams 101 formed by the splicing assembly 10 are each provided with a first blocking structure, thereby providing better protection for electrical components and the rim 21 within the receiving cavity. The first blocking structure includes a first blocking member 15, which includes a first connecting portion 151 and a first blocking portion 152. One end of the first connecting portion 151 is connected to either the first splicing edge or the second splicing edge and extends into the receiving cavity. The first blocking portion 152 is connected to the end of the first connecting portion 151 away from the first seam 101. The first blocking portion 152 and the first connecting portion 151 are arranged at an angle, and the first blocking portion 152 is spaced from the inner end of the first seam 101 in the depth direction of the first seam 101. Figure 4As shown, the cross-section of the structure formed by the first blocking part 152 and the first connecting part 151 is L-shaped, wherein the first blocking part 152 blocks the space between the inner end of the first joint 101 and the rim 21. The first blocking part 152 can effectively block foreign objects and static electricity entering from the first joint 101, thereby reducing the risk of foreign objects and static electricity transmission negatively affecting electrical components.
[0057] Furthermore, the first blocking structure also includes a second blocking member 16, which includes a second connecting portion 161. One end of the first connecting portion 151 is connected to one of the first splicing edge and the second splicing edge, and the second connecting portion 161 is connected to the other of the first splicing edge and the second splicing edge, extending into the receiving cavity. The second connecting portion 161 is located on the side of the first blocking portion 152 facing the first seam 101. By providing the second connecting portion 161, foreign objects and static electricity entering from the first seam 101 can be guided by the slit between the first connecting portion 151 and the second connecting portion 161 to move in the direction of the first blocking portion 152, preventing foreign objects and static electricity from randomly spreading in other directions and affecting electrical components. Under the guidance of the first connecting portion 151 and the second connecting portion 161, foreign objects and static electricity will reach the first blocking portion 152 along a set path and be intercepted by the first blocking portion 152.
[0058] Furthermore, the second blocking member 16 also includes a second blocking portion 162, which is connected to the end of the second connecting portion 161 near the first blocking portion 152. The second blocking portion 162 extends towards the first connecting portion 151 to block the space between the first blocking portion 152 and the first seam 101. By providing the second blocking portion 162, foreign objects and static electricity released from the inner end of the first seam 101 will not move directly towards the first blocking portion 152. Instead, under the obstruction of the second blocking portion 162, they will first move towards the first connecting portion 151, then pass through the gap between the first connecting portion 151 and the second blocking portion 162, and then be transmitted to the first blocking portion 152. It can be seen that the second blocking portion 162 makes the subsequent transmission path of foreign objects and static electricity entering from the first seam 101 longer and more tortuous. In addition, the blocking effect of the second blocking portion 162 itself can also cause some foreign objects and static electricity to stop (or disappear) at the second blocking portion 162. Therefore, by providing the second blocking part 162, the first blocking structure has a better effect in blocking and intercepting foreign objects and static electricity.
[0059] Furthermore, the first blocking member 15 also includes a first limiting part 153, which is disposed at the end of the first blocking part 152 away from the first connecting part 151. The first limiting part 153, the first blocking part 152, and the first connecting part 151 together form a first slot 154, and the second blocking member 16 engages with the first slot 154. In this embodiment, since the first blocking member 15 forms a hook-shaped structure, it engages with the second blocking member 16. Therefore, the first blocking structure not only blocks and intercepts foreign objects and static electricity, but also achieves the connection between the first housing 11 and the second housing 12. The first limiting part 153 extends partially to the side of the second blocking member 16 away from the first connecting part 151, thus limiting the second blocking member 16 and preventing the first housing 11 and the second housing 12 from being in a predetermined direction (in... Figure 4 The steering wheel cover 1 separates from the steering wheel in the left-right direction. At the same time, the first limiting part 153 increases the transmission path of foreign objects and static electricity, and makes the transmission path more tortuous, thus increasing the probability that foreign objects and static electricity are intercepted by the first blocking structure, thereby better protecting the electrical components inside the steering wheel cover 1.
[0060] Figure 5 This is a cross-sectional view of the first housing 11 in one embodiment of this application. (In conjunction with...) Figure 4 and Figure 5 As shown, the first housing 11 has two first splicing edges, and the second housing 12 has two second splicing edges. The two first splicing edges and the two second splicing edges are spliced together to form two first seams 101. One of the first splicing edges of the first housing 11 is provided with a first blocking member 15, and the other first splicing edge is provided with a second blocking member 16. Correspondingly, one of the second splicing edges of the second housing 12 is provided with a second blocking member 16, and the other second splicing edge is provided with a first blocking member 15.
[0061] Optionally, the first blocking structure can extend along the circumference of the steering wheel as a whole. The circumferential dimension of the first blocking structure is approximately equal to the length of the first seam 101 in that direction, allowing the first seam 101 to be completely blocked by the first blocking structure. This improves the blocking effect of the first blocking structure against foreign objects and static electricity. Alternatively, in an optional embodiment, multiple first blocking structures are provided at each first seam 101 of the splicing assembly 10. These multiple first blocking structures are arranged at intervals along the circumference of the steering wheel, so that parts of the first seam 101 are blocked by the first blocking structures. This reduces the size of the first blocking structure and provides targeted protection. For example, the first blocking structure can be provided at locations with more electrical components, while no first blocking structure can be provided at the first seam 101 corresponding to locations with fewer electrical components.
[0062] Figure 6 for Figure 2 Sectional view along direction B; Figure 7 for Figure 6 A magnified view of section VII in the middle. (See image below.) Figure 6 and Figure 7 As shown, the second blocking structure includes a third blocking member 17, which includes a third connecting portion 171 and a third blocking portion 172. One end of the third connecting portion 171 is connected to the splicing end of one of the two adjacent splicing components 10 and extends into the splicing component 10 along the depth direction of the second joint 102. One end of the third blocking portion 172 is connected to the end of the third connecting portion 171 away from the second joint 102. The third blocking portion 172 and the third connecting portion 171 are arranged at an angle. The third blocking portion 172 is spaced apart from at least a portion of the second joint 102 in the depth direction of the second joint 102.
[0063] In this embodiment, the cross-section of the structure formed by the third connecting portion 171 and the third blocking portion 172 is L-shaped. Similar to the function of the first blocking member 15 in the first blocking structure, the third blocking portion 172 can effectively block foreign objects and static electricity entering from the second joint 102, thereby reducing the risk of foreign objects and static electricity affecting the electrical components in the cavity. Furthermore, the second blocking structure also includes a fourth blocking member 18, which includes a fourth connecting portion 181 and a fourth blocking portion 182. The third connecting portion 171 and the fourth connecting portion 181 are respectively connected to two adjacent splicing ends. The fourth connecting portion 181 extends towards the third blocking portion 172 along the depth direction of the second joint 102, and one end of the fourth blocking portion 182 is connected to the fourth connecting portion 181, while the other end extends towards the third connecting portion 171.
[0064] In this embodiment, the inner end of the second seam 102 is located between the third connecting part 171 and the fourth connecting part 181. When foreign objects or static electricity enter from the second seam 102, they are restricted by the third connecting part 171 and the fourth connecting part 181 and will not spread randomly. The cross-section of the fourth blocking member 18 is L-shaped. When foreign objects or static electricity enter from the second seam 102 and are transmitted towards the center of the cavity, they are first blocked by the fourth blocking part 182, changing their direction of movement and instead being transmitted towards the third connecting part 171. After passing through the gap between the third connecting part 171 and the fourth blocking part 182, they are again blocked by the third blocking part 172. It can be seen that the structural design of the third blocking member 17 and the fourth blocking member 18 in this embodiment makes the transmission path of foreign objects and static electricity entering from the second seam 102 longer and more tortuous, making it difficult for foreign objects and static electricity to affect the electrical components inside the steering wheel cover 1 through the second blocking structure.
[0065] Furthermore, the third blocking member 17 also includes a second limiting part 173, which is connected to the end of the third blocking part 172 away from the third connecting part 171. The third connecting part 171, the third blocking part 172, and the second limiting part 173 are sequentially connected to form a second slot. The fourth blocking member 18 is inserted into the second slot. Specifically, the end of the fourth blocking part 182 extends into the second slot, and at least a portion of the fourth blocking part 182 is located within the second slot. The second limiting part 173 makes the transmission path of foreign objects and static electricity longer and more tortuous, making it less likely for foreign objects and static electricity to affect electrical components through the second blocking structure. In addition, the third blocking member 17 and the fourth blocking member 18 form a snap-fit engagement, realizing the connection of two adjacent splicing components 10. The second limiting part 173 has a limiting effect on the fourth blocking member 18, making it less likely for two adjacent splicing components 10 to separate in the circumferential direction of the steering wheel, thereby improving the structural stability of the steering wheel cover 1.
[0066] like Figure 7 As shown, furthermore, an electrical connection structure 19 is also provided inside the steering wheel cover 1, and a second blocking structure is positioned between the electrical connection structure 19 and the second joint 102. The second blocking structure can effectively reduce the risk of the electrical connection structure 19 being damaged by foreign objects or static electricity.
[0067] It should be understood that the second joint 102 in this embodiment is an annular joint. Optionally, the second blocking structure can be configured to be continuous in the circumferential direction of the second joint 102, thereby providing complete protection for the second joint 102; in some other embodiments, the second blocking structure can also be selectively configured at local locations of the second joint 102 to protect key locations.
[0068] Figure 8 This is an exploded view of the steering wheel frame 2 and the housing in one embodiment of this application; Figure 9 This is an exploded view of the substrate 13 and functional layer 135 of the housing in an embodiment of this application. Please refer to... Figure 5 , Figure 8 and Figure 9 As shown, optionally, the housing (including the first housing 11 and the second housing 12) includes a substrate 13 and a covering layer 14. The substrate 13 has an inner side facing the cavity and an outer side facing away from the cavity. The covering layer 14 covers the outer side of the substrate 13, and the blocking structure is connected to the substrate 13.
[0069] Optionally, a filling cavity is formed inside the substrate 13, and a functional layer 135 is disposed within the filling cavity. A wire-passing hole 134 is formed on the substrate 13 for wires connected to the functional layer 135 to pass through. The functional layer 135 is used to implement steering wheel-related functions, such as heating. Optionally, the functional layer 135 includes one or a combination of copper foil, conductive fabric, metal wire, and metal mesh, forming a conductive and heating module.
[0070] In this embodiment, the wire hole 134 is formed on the side of the substrate 13 away from the covering layer 14, which facilitates the connection of wires to other devices (such as circuit boards) inside the housing.
[0071] Optionally, the substrate 13 includes an inner shell 131 and an outer shell 132, which together form a filling cavity for accommodating the functional layer 135. The inner shell 131 is closer to the rim 21 than the outer shell 132, and a wire through hole 134 is formed on the inner shell 131. Figure 9 As shown, a filling groove 133 is formed on the side of the inner shell 131 facing the outer shell 132. During shell assembly, the functional layer 135 can be first attached to the filling groove 133, then the outer shell 132 can be assembled onto the inner shell 131, and finally, a covering layer 14 can be attached to the outer shell 132. Optionally, the outer shell 132 and the inner shell 131 can be made of the same or different materials. For example, the inner shell 131 can be made of a material with a certain strength, such as plastic, while the outer shell 132 can be a plastic part of the same material, formed by injection molding, so that the outer shell 132 and the inner shell 131 ultimately form an integral structure. Alternatively, in other embodiments, the outer shell 132 can be formed using a filler material different from that of the inner shell 131.
[0072] In this embodiment, the barrier structure (including the first barrier structure and the second barrier structure) and the inner shell 131 can be made of the same material, and the barrier structure and the inner shell 131 can be an integral structure, such as by injection molding.
[0073] In this embodiment, the functional layer 135 is encapsulated by the substrate 13, which protects the functional layer 135 from water flow, moisture, and dust, thereby improving the reliability of the functional layer 135. It should be understood that in other optional embodiments, the functional layer 135 may be omitted, that is, the substrate 13 may be solid without a filling cavity.
[0074] Optionally, such as Figure 4 and Figure 7As shown, the edge of the covering layer 14 extends between the substrates 13 of the two adjacent housings, that is, at least a portion of the seam is formed between the covering layers 14 of the two housings. This ensures that the outer surface of the steering wheel cover 1 is entirely formed by the covering layer 14, and the burrs on the edge of the covering layer 14 are not exposed, allowing the steering wheel cover 1 to present a better appearance and a better feel.
[0075] Optionally, the material of the covering layer 14 is selected from at least one of leather, artificial leather and fabric.
[0076] In summary, this application provides a steering wheel cover 1 and a steering wheel. The steering wheel cover 1 includes multiple shells, which are spliced together to form a cavity for covering the wheel rim 21. A seam is formed between adjacent shells, with an inner end near the cavity and an outer end away from the cavity in its depth direction. A blocking structure connected to the shells is provided inside the steering wheel cover 1, blocking at least part of the inner end of the seam. By providing a blocking structure at the inner end of the seam, foreign objects (such as water flow, water vapor, dust, etc.) and static electricity, even after passing through the seam, will be blocked by the blocking structure on the inner side of the steering wheel cover 1, thereby reducing the risk of foreign objects and static electricity directly reaching electrical components after passing through the seam. Furthermore, when foreign objects are blocked by the blocking structure, they remain within the blocking structure due to the blocking effect, making further movement difficult, thus alleviating the problem of rapid diffusion of foreign objects within the steering wheel cover 1 after passing through the seam. Therefore, the steering wheel cover 1 provided by this application can effectively protect the electrical components inside the steering wheel and improve the reliability of the steering wheel.
[0077] The steering wheel provided in this embodiment includes a steering wheel frame 2 and the aforementioned steering wheel cover 1. The steering wheel frame 2 includes a rim 21, and the steering wheel cover 1 covers the rim 21. This steering wheel has better reliability.
[0078] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
