Description

Technical Field

[0001] The utility model relates to the technical field of vehicle steering system components, in particular to a vehicle steering wheel mounting structure and a vehicle. Background Art

[0002] Currently, steering wheels on vehicles are typically installed and removed using standard fastener nuts (with or without washers) and removed using specialized tools such as pullers. This specialized tool is required because the steering wheel and steering column utilize a tapered fit. This fit ensures coaxial assembly and a secure connection between the two tapered surfaces, but it creates significant friction between the two conical contact surfaces, making the steering wheel difficult to remove.

[0003] In the prior art, special tools must be used to disassemble a vehicle steering wheel, which has several inconveniences: 1. The vehicle's onboard tools do not carry such special tools. When the steering wheel needs to be disassembled for inspection and repair, the driver cannot do it independently and must go to a repair shop. Especially when a fault occurs in the middle of a journey, the inability to quickly troubleshoot the fault will delay the driver's journey and also increase the driver's financial expenses; 2. Special tools are relatively complicated to assemble and operate. Even if the driver, as a non-professional, purchases special tools on his own, it is difficult to quickly and conveniently disassemble the steering wheel for inspection and repair.

[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] like Figures 1 to 4As shown, the first embodiment of the present invention provides a vehicle steering wheel mounting structure, which includes a steering wheel body 1, a steering column 2 and a fastener 3. The steering wheel body 1 has a mounting sleeve 11, and one end of the steering column 2 passes through the mounting sleeve 11 and is connected to the mounting sleeve 11; the fastener 3 includes a mounting block 31 and a disassembly block 32 that are connected to each other. The mounting block 31 can be detachably connected to one end of the steering column 2, and the disassembly block 32 can be detachably connected to the mounting sleeve 11; wherein, the fastener 3 has an installation condition and a disassembly condition. In the installation condition, the mounting block 31 is connected to one end of the steering column 2, and the end face of the mounting block 31 abuts the end face of the mounting sleeve 11; in the disassembly condition, the disassembly block 32 is connected to the mounting sleeve 11 and can abut the end face of one end of the steering column 2 to separate the steering column 2 and the mounting sleeve 11.

[0031] With the vehicle steering wheel mounting structure of the present invention, during installation, the mounting block 31 is connected to one end of the steering column 2, and the end surface of the mounting block 31 abuts the end surface of the mounting sleeve 11, thereby achieving connection between the steering column 2 and the steering wheel body 1. At the same time, when the steering wheel body 1 needs to be disassembled for troubleshooting and maintenance, the mounting block 31 and the steering column 2 can be disassembled. Then, the disassembly block 32 is connected to the mounting sleeve 11 and abuts the end surface of one end of the steering column 2. In this way, by continuing to screw the disassembly block 32, the disassembly block 32 can continue to press the steering column 2 downward, thereby achieving separation between the steering column 2 and the steering wheel body 1. With the vehicle steering wheel mounting structure of the present invention, the independent design of the mounting block 31 and the disassembly block 32 on the fastener 3 enables a single component to be used in different ways to meet the needs of fast installation and removal of the steering wheel body 1. No special tools are required, the operation is simple, and the problem of inconvenient steering wheel disassembly in the prior art is effectively solved.

[0032] Optionally, the mounting block 31 can be detachably connected to one end of the steering column 2, and the disassembly block 32 can be detachably connected to the mounting sleeve 11, wherein the detachable connection method includes but is not limited to a threaded connection or a snap connection.

[0033] In this embodiment, if Figure 1 and Figure 2 As shown, the mounting block 31 has a mounting hole 311. Under the installation condition, one end of the steering column 2 can be extended into the mounting hole 311 and is threadedly connected to the inner wall of the mounting hole 311. The mounting block 31 can be screwed until the end face of the mounting block 31 facing the mounting hole 311 abuts against the end face of the mounting sleeve 11. At this time, the steering column 2 and the steering wheel body 1 can be fixed by the mounting block 31.

[0034] Furthermore, in this solution, the inner wall of the mounting hole 311 is provided with a first internal thread, and the outer wall of one end of the steering column 2 is provided with a first external thread. By connecting the first internal thread and the first external thread, the connection between one end of the steering column 2 and the mounting block 31 can be achieved.

[0035] Optionally, the threaded connection between one end of the steering column 2 and the inner wall of the mounting hole 311 may also be a bolt welding spiral connection, a screw snap connection, or a self-tapping screw connection.

[0036] Specifically, if Figure 1 、 Figure 3 and Figure 4 As shown, the disassembly block 32 has a disassembly hole 321. During disassembly, the side wall of the disassembly hole 321 is threadedly connected to one end of the mounting sleeve 11, while the top wall of the disassembly hole 321 abuts against the end surface of one end of the steering column 2. With this arrangement, by twisting the disassembly block 32, the top wall of the disassembly hole 321 can exert a downward pressure on the steering column 2, causing the steering column 2 to separate from the steering wheel body 1.

[0037] Among them, the side wall of the disassembly hole 321 is provided with a second internal thread, and the outer wall of the mounting sleeve 11 is provided with a second external thread. The second internal thread and the second external thread are connected, so that the steering column 2 and the steering wheel body 1 can be separated by screwing the disassembly block 32.

[0038] In this embodiment, to ensure sufficient travel distance when the removal block 32 is screwed, allowing the steering column 2 to be disengaged from the steering wheel body 1, the steering wheel body 1 includes an annular groove 4 surrounding the mounting sleeve 11. The depth of the removal hole 321 is h, and the distance between the top wall of the removal hole 321 and the bottom wall of the annular groove 4 is s, where s>h. By limiting the depth h of the removal hole 321 and the distance s between the top wall of the removal hole 321 and the bottom wall of the annular groove 4 to within the aforementioned ranges, sufficient travel distance can be ensured when the removal block 32 is screwed.

[0039] like Figure 4 As shown, surface b is the end surface of the disassembly block 32 facing the installation sleeve 11, surface d is the end surface of the installation sleeve facing the disassembly block 32, and L is the distance from surface b to surface d. It can be seen that L can ensure that there is sufficient moving distance when screwing the disassembly block 32.

[0040] It should be noted that, under the disassembly condition, the mounting block 31 is disassembled and then reversed 180°, and the second internal thread of the disassembly hole 321 is connected to the second external thread of the mounting sleeve 11. As the disassembly block 32 is screwed into the mounting sleeve 11, the top wall of the disassembly hole 321 slowly contacts the end face of one end of the steering column 2; since there is still a distance L between the b surface and the d surface after the top wall of the disassembly hole 321 contacts the end face of one end of the steering column 2, the disassembly block 32 can continue to be tightened. At this time, the thread lift generated by the tightening force will generate a strong extrusion force between the top wall of the disassembly hole 321 and the end face of one end of the steering column 2, forcing the steering column 2 and the steering wheel body 1 to have a tendency to separate. When the extrusion force exceeds the friction resistance generated after the connection between the steering column 2 and the mounting sleeve 11, the conical surface fit is disengaged, and the steering wheel body 1 is separated from the steering column 2.

[0041] like Figure 1 As shown, the outer wall of the mounting block 31 has an operating structure 312 that matches the shape of the disassembly tool. This arrangement makes it easy to screw the mounting block 31 through the disassembly tool, making operation easier and faster.

[0042] Alternatively, the outer wall of the disassembly block 32 also has an operating structure 312 that matches the shape of the disassembly tool. Similarly, it is also convenient to screw the installation block 31 through the disassembly tool.

[0043] Alternatively, the outer walls of the installation block 31 and the outer walls of the removal block 32 each have an operating structure 312 that matches the shape of the disassembly tool. The operating structure 312 includes, but is not limited to, a polygonal or arc-shaped structure. In this embodiment, the operating structure 312 is a hexagonal structure that matches the operating surface of a universal disassembly wrench.

[0044] The advantages of the vehicle steering wheel mounting structure of the present invention are as follows:

[0045] 1. The fastener 3 of the present invention realizes the rapid installation and removal of the steering wheel body 1 through the independent design of the installation block 31 and the removal block 32;

[0046] 2. The fastener 3 designed in the present invention has a simple structure and low cost compared to special tools (such as pullers);

[0047] 3. The steering wheel body 1 can be disassembled without the aid of special tools (such as pullers), and the operation is simple and easy. The driver no longer needs to go to a repair shop to disassemble the steering wheel, saving a lot of time and money.

[0048] The second embodiment of the present invention further provides a vehicle, comprising a vehicle body, a steering wheel body 1, a steering column 2, and a vehicle steering wheel mounting structure according to any of the above schemes, wherein the steering wheel body 1 is connected to one end of the steering column 2 via a fastener 3 of the vehicle steering wheel mounting structure, and the other end of the steering column 2 is mounted on the vehicle body. In the vehicle of the present invention, during installation, the mounting block 31 is connected to one end of the steering column 2, and the end face of the mounting block 31 abuts the end face of the mounting sleeve 11, thereby achieving connection between the steering column 2 and the steering wheel body 1; at the same time, when the steering wheel body 1 needs to be disassembled for inspection and maintenance, in this case, during disassembly, the mounting block 31 and the steering column 2 can be disassembled, and then the disassembly block 32 is connected to the mounting sleeve 11, and abuts the end face of one end of the steering column 2. In this way, by continuing to screw the disassembly block 32, the disassembly block 32 can continue to press the steering column 2 downward, thereby achieving separation of the steering column 2 and the steering wheel body 1. The vehicle utilizing the present invention realizes the independent design of the mounting block 31 and the disassembly block 32 on the fastener 3, so that one component can be used in different ways to meet the quick installation and disassembly of the steering wheel body 1 respectively; and no special tools are required, the operation is simple, and the problem of inconvenient steering wheel disassembly in the prior art is effectively solved.

[0049] Specifically, the steering wheel body 1 comprises a steering wheel housing and a mounting sleeve 11. The steering wheel body 1 has a central hole. The mounting sleeve 11 passes through the central hole and connects to the inner wall of the central hole. The mounting sleeve 11 is connected to one end of the steering column 2 via a fastener 3. This arrangement facilitates the connection of the mounting sleeve 11. The mounting sleeve 11 and the inner wall of the central hole are connected by welding or by forming an integral structure.

[0050] Furthermore, the steering column 2 includes a conical section and a cylindrical section connected to each other, and a portion of the conical section and the cylindrical section penetrates the mounting sleeve 11 and is connected to the inner wall of the mounting sleeve 11. This arrangement connects the conical section to the inner wall of the mounting sleeve 11, making the installation of the steering column 2 and the steering wheel body 1 more reliable and stable.

[0051] An embodiment of the present invention provides a vehicle, and the disassembly and assembly process of the steering wheel body 1 and the steering column 2 is as follows: if the steering wheel body 1 and the steering column 2 need to be installed, under the installation condition: first align the mounting block 31 with one end of the steering column 2, and then use the disassembly and assembly tool to screw and connect the mounting hole 311 of the mounting block 31 and one end of the steering column 2 until the end surface of the mounting block 31 facing the mounting sleeve 11 abuts against the end surface of the mounting sleeve 11, so that the steering column 2 can be fixed to the steering wheel body 1.

[0052] If the steering wheel body 1 and steering column 2 need to be disassembled, the following steps are performed during disassembly: first, the mounting block 31 and the steering column 2 are disassembled using a disassembly tool; then, the disassembly block 32 is aligned with the mounting sleeve 11, and the disassembly tool is used to screw the disassembly hole 321 of the disassembly block 32 and the mounting sleeve 11 together, with the top wall of the disassembly hole 321 contacting the end face of one end of the steering column 2; the disassembly block 32 is further screwed, so that the top wall of the disassembly hole 321 presses the steering column 2 downward until the steering column 2 is separated from the steering wheel body 1. This method eliminates the need for specialized tools (such as a puller), is simple to operate, and eliminates the need for drivers to visit a repair shop for steering wheel disassembly.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
