Description

Technical Field

[0001] This application relates to the field of automotive parts technology, specifically to a steering wheel, a steering wheel assembly, and a vehicle. Background Technology

[0002] Currently, the surface of car steering wheels is mainly covered with leather (imitation leather, genuine leather), which is fixed to the steering wheel surface by adhesive and sewing. Steering wheels produced in this way are difficult to replace the leather in the future.

[0003] A related technology provides a steering wheel in which a leather cover wraps around the periphery of a foam body, with both ends embedded in an inlay cavity. A decorative element, at least partially embedded from the middle of both ends of the leather cover into the inlay cavity, is press-fitted to both ends of the leather cover to secure them within the cavity. However, in practical applications, the friction between the decorative element and the leather cover is significant, making it difficult to remove the decorative element from the gap between the two ends of the leather cover and inconvenient for the user to replace the cover. Utility Model Content

[0004] One objective of this utility model is to provide a steering wheel that solves the problem of inconvenient replacement of existing steering wheel surface covers. A second objective of this utility model is to provide a steering wheel assembly. A third objective of this utility model is to provide a vehicle.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] On one hand, this application provides a steering wheel, including a steering wheel body, a first connecting member, an outer wrapping layer, a second connecting member, and a third connecting member. A connecting groove is provided on the surface of the steering wheel body. The first connecting member is connected to the steering wheel body and disposed within the connecting groove. The outer wrapping layer is fitted around the steering wheel body and extends circumferentially along the steering wheel body. The second connecting member is connected to one end of the outer wrapping layer. The third connecting member is connected to the other end of the outer wrapping layer. Both the second and third connecting members are detachably connected to the first connecting member.

[0007] Based on the aforementioned technical means, the outer layer can cover the outside of the steering wheel body, thus providing the driver with a better grip. Both ends of the outer layer can be connected to the first connector via a second and a third connector, thereby fixing the outer layer to the outside of the steering wheel body. Since both the second and third connectors are detachably connected to the first connector, when the outer layer becomes oily or damaged, the user can separate the second and third connectors from the first connector, remove the outer layer from the steering wheel body, and replace it with a new one. The removal and installation of the outer layer is simple and convenient, allowing users to replace it themselves. When the outer layer becomes oily or damaged, the user does not need to replace the entire steering wheel, reducing vehicle operating costs. Furthermore, after replacing the outer layer, the steering wheel maintains its original size, ensuring a comfortable grip during driving.

[0008] In some embodiments, the steering wheel body includes a hub, a rim, and spokes. The rim is disposed around the periphery of the hub and is spaced apart from the hub. An outer layer is fitted over the outer side of the rim and extends circumferentially along the rim. One end of each spoke is connected to the hub, and the other end is connected to the rim. A connecting groove is located on the side of the rim closer to the hub.

[0009] According to the aforementioned technical means, the connecting groove is located on the inner ring of the wheel rim. When the driver's hand is gripping the wheel rim, the connecting groove will not affect the driver's feel.

[0010] In some embodiments, there are multiple connecting slots, and there are multiple first connectors, second connectors, and third connectors.

[0011] According to the above technical means, after the second and third connecting parts are connected with the first connecting part, they can fix the position of the outer layer wrapping at multiple different positions, thereby ensuring the stability of the outer layer wrapping at various points and preventing the outer layer wrapping from sliding relative to the steering wheel body.

[0012] In some embodiments, the outer layer has multiple first connecting portions and multiple second connecting portions at both ends. Multiple second connecting members are connected to the multiple first connecting portions, and multiple third connecting members are connected to the multiple second connecting portions. The multiple first connecting portions and multiple second connecting portions are all inserted into multiple connecting slots, and the first connecting portions and second connecting portions abut against each other along the stacking direction of the first connecting portions and second connecting portions.

[0013] According to the above-mentioned technical means, the first connecting part and the second connecting part are squeezed against each other, and the first connecting part and the second connecting part are not easy to detach from the connecting groove, which can improve the stability of the outer layer wrapping.

[0014] In some embodiments, along a first direction, a plurality of first connectors are disposed opposite each other on the sidewall of the connecting groove, and a second connector is located on the side of the first connecting portion away from the second connecting portion, and a third connector is located on the side of the second connecting portion away from the first connecting portion. The first direction is parallel to the stacking direction of the first connecting portion and the second connecting portion.

[0015] According to the above-mentioned technical means, the two sidewalls of the connecting groove extend along the circumference of the wheel rim. The sidewalls of the connecting groove can provide a large installation area for the first connecting member, so that the first connecting member can fully contact the second connecting member and the third connecting member, thereby ensuring the stability of the connection.

[0016] In some embodiments, the outer layer of the wheel rim includes multiple splicing segments along its circumference, and each splicing segment is provided with a first connecting portion and a second connecting portion.

[0017] Based on the above-mentioned technical means, the outer wrap can be divided into multiple separate areas according to the shape of the wheel rim. During the process of putting the outer wrap onto the wheel rim, multiple splicing segments can be put onto the wheel rim in sequence. The multiple splicing segments will not interfere with each other during the putting process, and the process of putting the outer wrap onto the wheel rim is more labor-saving.

[0018] In some embodiments, the wheel rim includes an inner frame and a foam layer. The inner frame is annular. The foam layer is fitted over the outer side of the inner frame, and a connecting groove is provided on the side of the foam layer near the wheel hub.

[0019] Based on the aforementioned technical methods, the internal frame serves as a fundamental supporting component to ensure the overall strength of the wheel rim. The foam layer enhances the feel, especially during long drives, significantly reducing hand fatigue. The soft material provides greater comfort and maintains warmth even in cold weather. The foam layer's strength is lower than that of the internal frame, facilitating the machining of connection grooves.

[0020] In some embodiments, the first connector, the second connector, and the third connector are all Velcro.

[0021] Using the aforementioned technical means, workers can attach the second and third connecting parts to the first connecting part to connect them together, thereby fixing the outer layer to the steering wheel body. When it is necessary to remove the outer layer, simply pull on both ends of the outer layer to separate the second and third connecting parts from the first connecting part, thus removing the outer layer from the steering wheel body.

[0022] On the other hand, this application embodiment also provides a steering wheel assembly, which includes the steering wheel described above.

[0023] Furthermore, embodiments of this application also provide a vehicle that includes the aforementioned steering wheel assembly.

[0024] Since the vehicle and steering wheel assembly provided in this application embodiment include the steering wheel in the first aspect, they can solve the same technical problems as the steering wheel described above and achieve the same technical effects, which will not be repeated here.

[0025] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0026] (1) The outer wrap can cover the outside of the steering wheel body, thus providing the driver with a better grip. The two ends of the outer wrap can be connected to the first connector via a second and a third connector, thereby fixing the outer wrap to the outside of the steering wheel body. Since both the second and third connectors are detachably connected to the first connector, when the outer wrap surface becomes oily or damaged, the user can separate the second and third connectors from the first connector, remove the outer wrap from the steering wheel body, and replace it with a new one. The removal and installation of the outer wrap is simple and convenient, allowing users to replace it themselves. When the outer wrap surface becomes oily or damaged, the user does not need to replace the entire steering wheel, reducing vehicle operating costs. Furthermore, after replacing the outer wrap, the steering wheel maintains its original size, ensuring a comfortable grip during driving.

[0027] (2) The connecting groove is located on the inner ring of the wheel rim. When the driver's hand is on the wheel rim, the connecting groove will not affect the driver's feel.

[0028] (3) After the second and third connectors are connected to the first connector, they can fix the position of the outer layer wrapping at multiple different positions, thereby ensuring the stability of the outer layer wrapping at various points and preventing the outer layer wrapping from sliding relative to the steering wheel body.

[0029] (4) The first connecting part and the second connecting part are squeezed against each other, and the first connecting part and the second connecting part are not easy to separate from the connecting groove, which can improve the stability of the outer layer wrapping.

[0030] (5) The two sidewalls of the connecting groove extend along the circumference of the wheel rim. The sidewalls of the connecting groove can provide a larger installation area for the first connecting member so that the first connecting member can fully contact the second connecting member and the third connecting member, thereby ensuring the stability of the connection.

[0031] (6) The outer wrap can be divided into multiple separate areas according to the shape of the wheel rim. During the process of putting the outer wrap on the wheel rim, multiple splicing segments can be put on the wheel rim in sequence. The multiple splicing segments will not interfere with each other during the process of putting on the outer wrap, and the process of putting the outer wrap on the wheel rim is more labor-saving.

[0032] (7) The internal frame serves as a basic support component to ensure the overall strength of the wheel rim. The foam layer provides a better feel, especially during long drives, significantly reducing hand fatigue. The soft material makes the hands feel more comfortable and keeps them warm even in cold weather. The strength of the foam layer is lower than that of the internal frame, making it easier for workers to machine connection grooves on it.

[0033] (8) The worker can attach the second and third connectors to the first connector to connect the second and third connectors together with the first connector, thereby fixing the outer layer to the steering wheel body. When it is necessary to remove the outer layer, simply pull the two ends of the outer layer to separate the second and third connectors from the first connector, thereby removing the outer layer from the steering wheel body.

Detailed Implementation

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] This application provides a vehicle including a vehicle body and a steering wheel assembly. The vehicle body has a driver's cabin inside, and the steering wheel assembly is disposed within the driver's cabin for controlling the vehicle's direction of travel.

[0043] It is understood that the vehicle provided in this application embodiment may also include other components, such as an engine, transmission mechanism, etc., to realize the basic functions of the vehicle.

[0044] A steering wheel assembly may include a steering wheel, a steering column, and a steering shaft. The steering shaft is connected to the steering wheel and is used to transmit the rotation of the steering wheel, while the steering column supports the steering shaft and provides the necessary passage for the steering shaft.

[0045] Understandably, a steering wheel assembly may include a power steering system and an airbag module to achieve the basic functions of the steering wheel assembly.

[0046] Next, the steering wheel provided in the embodiments of this application will be further described, such as... Figure 1 As shown, the steering wheel 100 may include a steering wheel body 1 and an outer wrapping 3. The outer wrapping 3 is fitted onto the outside of the steering wheel body 1 and extends circumferentially along the steering wheel body 1.

[0047] In practical applications, the outer layer 3 can cover the outside of the steering wheel body 1, thereby providing the driver with a better grip. For example, the outer layer 3 can be genuine leather, which has a good tactile feel and sweat absorption. It is understood that the outer layer 3 can also be made of other materials, and different materials can be selected according to actual usage needs.

[0048] like Figure 2As shown, the surface of the steering wheel body 1 is provided with a connecting groove 11. The steering wheel 100 may also include a first connecting member 2, a second connecting member 4, and a third connecting member 5. The first connecting member 2 is disposed in the connecting groove 11, the second connecting member 4 is connected to one end of the outer wrapping 3, and the third connecting member 5 is connected to the other end of the outer wrapping 3. Both the second connecting member 4 and the third connecting member 5 are detachably connected to the first connecting member 2.

[0049] In practical applications, the two ends of the outer wrapping 3 can be connected to the first connector 2 through the second connector 4 and the third connector 5, thereby fixing the outer wrapping 3 to the outside of the steering wheel body 1.

[0050] Since both the second connector 4 and the third connector 5 are detachably connected to the first connector 2, when the surface of the outer wrapping 3 becomes oily or damaged, the user can separate the second connector 4 and the third connector 5 from the first connector 2, thereby removing the outer wrapping 3 from the steering wheel body 1 and replacing it with a new one. The removal and installation of the outer wrapping 3 is simple and convenient, allowing users to replace it themselves.

[0051] Thus, in practical applications, if the outer layer 3 becomes stained with oil or is damaged, the user does not need to replace the entire steering wheel 100, reducing vehicle operating costs. Furthermore, after replacing the outer layer 3, the steering wheel 100 can maintain its original size, ensuring a comfortable grip during driving.

[0052] Understandably, in practical applications, the outer wrapping 3 can be a leather case or a covering layer made of other materials.

[0053] Since the first connector 2 is disposed within the connecting groove 11, the connecting groove 11 can provide clearance for the first connector 2, and the first connector 2, being disposed on the steering wheel body 1, will not form a protrusion on the surface of the steering wheel body 1. In this way, the smoothness of the surface of the steering wheel 100 after the outer layer 3 covers the steering wheel body 1 can be guaranteed, making it more comfortable for the driver to hold the steering wheel 100.

[0054] To enable the second connector 4 and the third connector 5 to be detachably connected to the first connector 2, in some embodiments, such as Figure 2 As shown, the first connector 2, the second connector 4, and the third connector 5 can be Velcro.

[0055] In practical application, workers attach the second connector 4 and the third connector 5 to the first connector 2 to connect them together, thus fixing the outer layer 3 to the steering wheel body 1. When it is necessary to remove the outer layer 3, simply pull on both ends of the outer layer 3 to separate the second connector 4 and the third connector 5 from the first connector 2, thereby removing the outer layer 3 from the steering wheel body 1.

[0056] In some embodiments, the first connector 2 can be glued to the connecting groove 11. Similarly, the second connector 4 and the third connector 5 can be glued to the outer wrapping 3. In practical applications, the glue used to bond the first connector 2, the second connector 4, and the third connector 5 can be a water-based adhesive. Compared to traditional adhesives, water-based adhesives emit fewer organic compounds, making the steering wheel 100 less prone to odor.

[0057] In some embodiments, such as Figure 1 As shown, the steering wheel body 1 may include a hub 12, a rim 13, and spokes 14. The rim 13 is disposed around the circumference of the hub 12, with a gap between it and the hub 12. An outer layer 3 is fitted around the outside of the rim 13 and extends circumferentially along the rim 13. One end of the spokes 14 is connected to the hub 12, and the other end is connected to the rim 13.

[0058] In practical applications, control buttons, airbag systems, and other related systems can be installed on the wheel hub 12 to enable the steering wheel 100 to perform its basic functions. The spokes 14 connect the wheel hub 12 to the wheel rim 13. The driver typically holds the outer side of the wheel rim 13 while driving; the outer wrapping 3 improves the driver's grip and facilitates operation of the steering wheel 100.

[0059] like Figure 2 As shown, the connecting groove 11 is located on the side of the wheel rim 13 closest to the hub 12. Thus, in practical application, the connecting groove 11 is located on the inner ring of the wheel rim 13. When the driver's hands are on the wheel rim 13, the connecting groove 11 will not affect the driver's grip.

[0060] It is understandable that, since the connecting groove 11 is located inside the wheel rim 13, after the second connecting piece 4 and the third connecting piece 5 are connected to the first connecting piece 2 in the connecting groove 11, both ends of the outer wrapping 3 are also located inside the wheel rim 13. This can prevent the gaps at both ends of the outer wrapping 3 from affecting the driver's grip on the steering wheel.

[0061] In practical applications, the outer wrapping 3 can avoid interference with the spokes 14 at the connection between the spokes 14 and the rim 13.

[0062] To reduce the weight of the steering wheel 100, in some embodiments, such as Figure 1 As shown, the hub 12 and spokes 14 can be provided with a hollow structure. This can effectively reduce the overall weight of the steering wheel 100.

[0063] To achieve the connection between the steering wheel 100 and the drive shaft, in some embodiments, such as Figure 1 As shown, a spline structure can be provided at the center of the wheel hub 12. In this way, the wheel hub 12 can be connected to the drive shaft through the spline structure, so that the drive shaft can rotate synchronously when the steering wheel 100 rotates.

[0064] In some embodiments, such as Figure 2 As shown, the wheel rim 13 may include an inner frame 131 and a foam layer 132. The inner frame 131 is annular, and the foam layer 132 is sleeved on the outside of the inner frame 131.

[0065] In practical applications, the internal frame 131 serves as a basic support component to ensure the overall strength of the wheel rim 13. The foam layer 132 enhances the feel, especially during long drives, significantly reducing hand fatigue. The soft material makes the hands feel more comfortable and maintains a certain level of warmth even in cold weather.

[0066] Foam layer 132 is located near wheel hub 12 ( Figure 1 A connecting groove 11 is provided on one side of the foam layer 132. In practical applications, the strength of the foam layer 132 is lower than that of the internal skeleton 131, making it easier for workers to process the connecting groove 11 on it. Alternatively, the connecting groove 11 can be directly formed in the foam layer 132 during the foaming process.

[0067] In some embodiments, such as Figure 2 As shown, the rim 13 may further include a filling layer 133, which is fitted over the outer side of the foam layer 132. In practical applications, the filling layer 133 may be made of an elastic material, and it can fit tightly against the inner surface of the outer wrapping 3 to prevent air pockets from forming in the outer wrapping 3. For example, the filling layer 133 may be polyurethane foam, which is elastic and provides a softer grip.

[0068] In some embodiments, such as Figure 2 As shown, the filling layer 133 may have an opening at the connecting groove 11 so that the second connector 4 and the third connector 5 can be connected to the first connector 2.

[0069] In some embodiments, the filler layer 133 can be bonded to the foam layer 132 with adhesive, thereby connecting the filler layer 133 and the foam layer 132 together. It is understood that the adhesive used to bond the filler layer 133 and the foam layer 132 can also be a water-based adhesive to reduce the emission of organic compounds and reduce the odor of the steering wheel 100.

[0070] In some embodiments, the number of connecting slots 11 can be multiple, and the number of first connectors 2, second connectors 4, and third connectors 5 can all be multiple. In practical applications, after the second connectors 4 and third connectors 5 are connected to the first connectors 2, they can fix the position of the outer wrapping 3 at multiple different locations, thereby ensuring the stability of the outer wrapping 3 at various points and preventing the outer wrapping 3 from sliding relative to the steering wheel body 1 locally.

[0071] In some embodiments, the outer casing 3 has multiple first connecting portions 31 and multiple second connecting portions 32 at both ends. Multiple second connecting members 4 are connected to the multiple first connecting portions 31, and multiple third connecting members 5 are connected to the multiple second connecting portions 32. In practical applications, the first connecting portions 31 and the second connecting portions 32 can provide installation positions for the second connecting members 4 and the third connecting members 5.

[0072] In practical applications, depending on the specific application, one or more second connecting parts 31 can be provided on one first connecting part 31, as long as the outer wrapping 3 can be stably mounted on the wheel rim 13. Correspondingly, one or more third connecting parts 32 can be provided on one second connecting part 32.

[0073] In some embodiments, such as Figure 2 As shown, multiple first connecting portions 31 and multiple second connecting portions 32 are inserted into multiple connecting slots 11. Along the stacking direction of the first connecting portions 31 and the second connecting portions 32, the first connecting portions 31 and the second connecting portions 32 abut against each other. In this way, the first connecting portions 31 and the second connecting portions 32 are pressed against each other, making it difficult for them to detach from the connecting slots 11, thus improving the stability of the outer wrapping 3.

[0074] Since multiple first connecting parts 31 and multiple second connecting parts 32 are inserted into multiple connecting grooves 11, in actual application, the second connecting part 4 and the third connecting part 5 are also located in the connecting groove 11. The part of the outer wrapping 3 that wraps around the surface of the wheel rim 13 is a flat part without any protrusions, and the outer wrapping 3 has a good fit with the surface of the wheel rim 13.

[0075] Understandably, in practical applications, the number of first connecting parts 31 and second connecting parts 32 that can be inserted into a connecting slot 11 can be set according to actual usage requirements. For example, one first connecting part 31 and one second connecting part 32 can be inserted into a connecting slot 11. Alternatively, one first connecting part 31 and two second connecting parts 32 can be inserted into a connecting slot 11.

[0076] In some embodiments, such as Figure 2 As shown, along the first direction X, a plurality of first connectors 2 are disposed opposite each other on the sidewall of the connecting groove 11, and the second connector 4 is located on the side of the first connecting portion 31 away from the second connecting portion 32, and the third connector 5 is located on the side of the second connecting portion 32 away from the first connecting portion 31. The first direction X is parallel to the stacking direction of the first connecting portion 31 and the second connecting portion 32.

[0077] In practical applications, the two sidewalls of the connecting groove 11 extend along the circumference of the wheel rim 13. The sidewalls of the connecting groove 11 can provide a larger installation area for the first connector 2, so that the first connector 2 can have sufficient contact with the second connector 4 and the third connector 5, thereby ensuring the stability of the connection.

[0078] In addition, the first connecting part 31 and the second connecting part 32 can press each other toward the side wall of the connecting groove 11, so that the second connecting member 4 and the third connecting member 5 can maintain a tight fit with the first connecting member 2 to improve the stability of the connection.

[0079] In some embodiments, such as Figure 1 As shown, along the circumference of the wheel rim 13, the outer wrapping 3 includes multiple splicing segments 34, and each of the multiple splicing segments 34 is provided with a first connecting part 31. Figure 2 ) and the second connecting part 32 ( Figure 2 In practical applications, the outer wrapping 3 can be divided into multiple separate areas according to the shape of the wheel rim 13. During the process of fitting the outer wrapping 3 onto the wheel rim 13, multiple splicing segments 34 can be sequentially fitted onto the wheel rim 13. The multiple splicing segments 34 will not interfere with each other during the fitting process, and the process of fitting the outer wrapping 3 onto the wheel rim 13 is more labor-saving.

[0080] For example, such as Figure 1 As shown, the wheel rim 13 can be divided into four parts along its circumference: top, bottom, left, and right. The bottom part of the wheel rim can be relatively straight, while the left and right parts and the top part can be curved. Correspondingly, there can also be four splicing segments 34, each of which can be adapted to the shape of different parts of the wheel rim 13.

[0081] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
