[0002] In modern automobile design and manufacturing, the steering wheel, as a key component for the driver to interact with the vehicle, its design not only concerns driving comfort and safety, but also directly affects the overall vehicle handling performance and user experience. However, in the design verification stage of the steering wheel, a crucial but often overlooked link is the disassembly and assembly convenience of the steering wheel.

[0003] Currently, the steering wheels of most automobiles on the market generally adopt a bolt fastening scheme. Although this design ensures the stability and safety of the steering wheel to a certain extent, it shows obvious limitations in scenarios such as scheme verification, maintenance and replacement, or personalized upgrade. Specifically, when it is necessary to disassemble the steering wheel for performance testing, design evaluation, or component replacement, the existing bolt fastening scheme requires technicians to first remove the panel covering the lower part of the steering wheel, and then use specific tools (such as wrenches, sockets, etc.) to disassemble multiple bolts one by one. This process is not only cumbersome and time-consuming, but also increases the operation difficulty and cost, especially for non-professionals.

[0004] In addition, frequent disassembly may cause unnecessary wear and damage to the steering wheel and its surrounding components, thereby affecting the overall performance and safety of the vehicle. Therefore, in the design verification stage of the steering wheel, it is particularly important to find a more convenient, efficient, and non-destructive fixing and disassembly scheme.

[0005] Based on the above background, the present technology aims to propose an innovative steering wheel fixing and disassembly mechanism to overcome the deficiencies of the existing bolt fixing scheme in terms of disassembly and assembly convenience. Content of the Utility Model

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] As Figure 1 shown is a common existing steering wheel fixing method. In the figure, the bolt marked with reference numeral A is used to fix the steering wheel. It is necessary to first remove the panel and then use a special tool to remove this bolt (in the figure, it is an internal hexagonal socket head cap screw) to remove the steering wheel; since the airbag is integrated under the panel, the disassembly process is not only troublesome but also has a certain degree of danger.

[0026] Embodiment 1

[0027] AsFigure 2 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , a quick-release steering wheel for testing includes a steering wheel body 1, a column mechanism 2 and a quick-release connection device 3; the quick-release connection device 3 includes a magnetic connection member 31, an electromagnetic connection member 32 and a control button 33; the electromagnetic connection member 32 remains magnetic when powered off and demagnetizes when powered on; the control button 33 is connected in series in the power supply circuit of the electromagnetic connection member 32; the magnetic connection member 31 is connected to the steering wheel body 1; the electromagnetic connection member 32 is fixed on the column mechanism 2; a steering damping member 11 is provided between the steering wheel body 1 and the magnetic connection member 31;

[0028] During use, the control button remains disconnected, and the steering wheel body 1 is connected to the column mechanism 2 through the magnetic connection member 31 and the electromagnetic connection member 32; closing the control button 33, the electromagnetic connection member 32 is powered on and demagnetizes, and the steering wheel body 1 can be disconnected from the column mechanism 2 to achieve quick disassembly, which is convenient for replacing the steering wheel, avoiding the potential danger when disassembling the airbag cover on the steering wheel. At the same time, only by installing the magnetic connection member 31 on the steering wheel body 1, the steering wheel can be quickly replaced, improving the efficiency of scheme verification.

[0029] The electromagnetic connection member 32 uses an electromagnet that demagnetizes when powered on (or the magnetic force is greatly reduced) and remains magnetic when powered off, which can reduce the power-on time of the component, reduce heat generation, and be safer. Because the steering wheel needs to maintain a stable connection for a long time, although using an electromagnet as the electromagnetic connection member 32 can also achieve the effect of quick disassembly, it means that the electromagnet needs to be powered on for a long time, which is easy to accumulate heat and reduce its service life; the electromagnet that demagnetizes when powered on is a commercially available mature product, so its specific structure and principle will not be elaborated here. In actual use, the corresponding specifications are selected according to the required magnetic force;

[0030] The steering damping member 11 includes a first adapter 111, a damping rotating shaft 112 and a second adapter 113; one side of the first adapter 111 is fixedly connected to the steering wheel and the other side is connected to the damping rotating shaft 112; one side of the second adapter 113 is connected to the damping rotating shaft 112 and the other side is fixedly connected to the magnetic connection member 31; the steering damping member 11 can simulate the steering damping of the steering wheel on an actual vehicle, which is convenient for verifying whether the design of the steering wheel is reasonable and whether the steering feel is appropriate.

[0031] The magnetic connection member 31 is made of iron and is CNC machined into a block with flat surfaces on both sides, and is provided with a plurality of connecting screw holes 311 thereon, which is convenient for expanding the steering wheel design sample to be verified, so that it has the function of quick installation and disassembly; the magnetic connection member 31 is fixedly connected to the second adapter 113 through the connecting screw holes 311.

[0032] Embodiment Two

[0033] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a quick-release steering wheel for testing includes a steering wheel body 1, a column mechanism 2, and a quick-release connection device 3; the quick-release connection device 3 includes a magnetic attraction connector 31, an electromagnetic connector 32, and a control button 33; the electromagnetic connector 32 remains magnetic when powered off and demagnetizes when powered on; the control button 33 is connected in series to the power supply circuit of the electromagnetic connector 32; the magnetic attraction connector 31 is connected to the steering wheel body 1; the electromagnetic connector 32 is fixed to the column mechanism 2; a steering damping member 11 is provided between the steering wheel body 1 and the magnetic attraction connector 31;

[0034] During use, the control button remains open, and the steering wheel body 1 is connected to the column mechanism 2 through the magnetic attraction connector 31 and the electromagnetic connector 32; closing the control button 33 causes the electromagnetic connector 32 to be powered on and demagnetize, and the steering wheel body 1 can be disconnected from the column mechanism 2 to achieve rapid disassembly, facilitating the replacement of the steering wheel, avoiding potential dangers when disassembling the airbag cover on the steering wheel, and at the same time, only by installing the magnetic attraction connector 31 on the steering wheel body 1, the steering wheel can be quickly replaced, improving the efficiency of scheme verification.

[0035] The electromagnetic connector 32 uses an electromagnet that demagnetizes (or significantly weakens the magnetic force) when powered on and remains magnetic when powered off, which can reduce the power-on time of the component, reduce heat generation, and be safer. Since the steering wheel needs to maintain a long-term stable connection, although using an electromagnet as the electromagnetic connector 32 can also achieve the effect of rapid disassembly, it means that the electromagnet needs to be powered on for a long time, which is prone to heat accumulation and reduces its service life; the electromagnet that demagnetizes when powered on is a commercially available mature product, so its specific structure and principle will not be elaborated here. In actual use, the corresponding specifications are selected according to the required magnetic force;

[0036] The steering damping member 11 includes a first adapter 111, a damping rotating shaft 112, and a second adapter 113; one side of the first adapter 111 is fixedly connected to the steering wheel and the other side is connected to the damping rotating shaft 112; one side of the second adapter 113 is connected to the damping rotating shaft 112 and the other side is fixedly connected to the magnetic attraction connector 31; the steering damping member 11 can simulate the steering damping of the steering wheel on an actual vehicle, facilitating the verification of whether the design of the steering wheel is reasonable and whether the steering feel is appropriate.

[0037] The magnetic attraction connector 31 is made of iron and is CNC machined into a block with flat surfaces on both sides, on which a number of connecting screw holes 311 are provided, facilitating the expansion of the steering wheel design sample to be verified, so that it has the function of rapid installation and disassembly; the magnetic attraction connector 31 is fixedly connected to the second adapter 113 through the connecting screw holes 311.

[0038] The quick-release connection device 3 further includes a housing 4; an adaptation groove 41 is provided on the surface of the housing 4; positioning holes are provided at the bottom of the adaptation groove 41. On the one hand, the housing 4 can protect the internal quick-release connection device 3, and on the other hand, the adaptation groove 41 can also be used to assist in positioning the installation of the steering wheel body 1.

[0039] Wherein, the electromagnetic connecting member 32 is arranged in the positioning hole; the shape of the adaptation groove 41 matches that of the magnetic attraction connecting member 31. When installing the steering wheel body 1, accurate alignment installation can be carried out through the adaptation groove 41.

[0040] The control button 33 is arranged on the side of the column mechanism 2, and the control button 33 can adopt a button with a self-locking function.

[0041] Advantages of the implementation of the present utility model:

[0042] A quick-release connection device composed of a magnetic attraction connecting member, an electromagnetic connecting member, and a control button is adopted to replace the traditional steering wheel fixing scheme; the magnetic attraction connection method replaces the bolt fixing scheme, which can meet the verification requirements of the steering wheel design scheme. An electromagnetic connecting member with power-off self-holding and power-on demagnetization is adopted, and the steering wheel body can be quickly disassembled after closing the control button, which not only improves the disassembly and replacement efficiency but also eliminates the trouble of disassembling the steering wheel airbag cover, improving safety; this scheme can quickly complete the disassembly and assembly of the steering wheel without disassembling the panel and without specific tools, thus greatly improving the verification efficiency and reducing the operation difficulty.
