[0041] The embodiment of the present application provides a clamping structure 11, a steering column cover 1 and a vehicle. The clamping structure 11 can be applied to the steering column cover 1, and the steering column cover 1 is arranged on the vehicle. Of course, the clamping structure 11 can also be applied to other aspects.

[0042] like Figures 1 to 3As shown, in a first aspect, an embodiment of the present application provides a snap connection structure 11, which includes a base 112, a wedge block 114, a baffle 116, and a snap plate 118.

[0043] The base 112 provides an installation basis for other components of the snap connection structure 11. Exemplarily, as Figure 2 shown, the base 112 is composed of a U-shaped plate structure and an arc-shaped plate structure. The U-shaped plate structure is fixedly connected to the arc-shaped plate structure. The U-shaped plate structure of the base 112 can improve the tensile strength of the base 112, and the arc-shaped plate structure can prevent the U-shaped plate structure from deforming, improve the anti-deformation ability, and improve the snap stability.

[0044] As Figure 1 shown, the wedge block 114 is fixedly installed on the base 112; Exemplarily, the wedge block 114 is fixedly connected to the base 112 by means of welding, integral molding, etc. Exemplarily, the wedge block 114 has a convex structure, and this convex structure is on the side of the wedge block 114 facing away from the base 112.

[0045] As Figure 1 and Figure 2 shown, the baffle 116 is fixedly installed on the base 112 and is separated from the wedge block 114, that is, there is a gap between the baffle 116 and the wedge block 114. The baffle 116 is located on one side of the wedge block 114, and more than one baffle 116 is provided. Exemplarily, as Figure 1 shown, one baffle 116 is provided, and the baffle 116 is located on one side of the wedge block 114. Exemplarily, the baffle 116 is fixedly connected to the base 112 by means of welding, integral molding, etc.

[0046] As Figure 3 shown, the snap plate 118 is snap-connected to the wedge block 114 and the baffle 116. A snap hole 1182 is provided on the snap plate 118, and the snap hole 1182 is a through hole. In the snap state, the wedge block 114 passes through the snap hole 1182. The design of the wedge block 114 ensures that after it penetrates into the hole, its larger end stops on the end face of the snap hole 1182, thus forming a locking mechanism, effectively preventing the wedge block 114 from accidentally coming out of the snap hole 1182 during the snap process.

[0047] At the same time, the baffle 116 is inserted into the clamping hole 1182. The function of the baffle 116 is that it can abut against the inner wall of the clamping hole 1182 and can apply an outward force by pushing the inner wall of the clamping hole 1182. This force will directly act on the clamping plate 118, limiting the displacement of the clamping plate 118 and keeping it in a fixed position. The baffle 116 not only enhances the connection stability between the clamping plate 118 and the wedge block 114, but also ensures that the clamping plate 118 will not easily move or loosen when subjected to external force. The entire clamping process is carried out efficiently, while ensuring the stability and reliability of the connection structure.

[0048] Exemplarily, the base 112 can be fixedly connected to the first preset structure, and the snap-in plate 118 can be fixedly connected to the second preset structure. The first preset structure is snap-connected to the snap-in plate 118 on the second preset structure through the wedge block 114 and the baffle 116 provided on the base 112, thereby realizing the snap-in connection between the first preset structure and the second preset structure.

[0049] In another embodiment, two baffles 116 are provided, wherein one baffle 116 is located on one side of the wedge block 114 , and the other baffle 116 is located on the other side of the wedge block 114 , and the two baffles 116 are arranged opposite to each other.

[0050] Exemplarily, the snap-on structure 11 is made of at least the following materials: polyhexamethylene adipamide, acrylonitrile-butadiene-styrene (ABS resin), polyamide resin (commonly known as nylon) or polyoxymethylene resin (POM).

[0051] like Figure 1 and Figure 2 As shown, in one embodiment, the snap-on structure 11 also includes a connecting plate 119, which is a rectangular elastic plate structure. The end of the connecting plate 119 close to the base 112 is a fixed end, and the end of the connecting plate 119 away from the base 112 is a connecting end. The fixed end is fixedly connected to the base 112, and the wedge block 114 is fixedly connected to the connecting end.

[0052] Exemplarily, the fixed end is fixedly connected to the base 112 by welding or integral molding. Exemplarily, the wedge block 114 is fixedly connected to the connecting end by welding or integral molding.

[0053] During the process of installing the wedge block 114 and the baffle plate 116 into the snap-in hole 1182 of the snap-in plate 118, when the wedge block 114 begins to enter the snap-in hole 1182, the edge of the snap-in hole 1182 will push the protruding structure of the wedge block 114. This pushing force will cause the wedge block 114 to drive the connecting plate 119 to move to a certain extent, thereby causing the connecting plate 119 to temporarily deform. This deformation is not permanent.

[0054] When the wedge block 114 and the baffle 116 successfully penetrate the clamping hole 1182, the inner wall of the clamping hole 1182 is out of contact with the wedge block 114, and the connecting plate 119 begins to rebound due to its own elasticity and gradually returns to its initial shape. At this time, the wedge block 114 is tightly in contact with the end face of the clamping hole 1182 on the clamping plate 118, forming a stable clamping connection. At the same time, the baffle 116 is also tightly attached to the inner wall of the clamping hole 1182, forming an additional fixing mechanism. At this time, the entire clamping structure 11 enters a stable clamping state.

[0055] By introducing the connecting plate 119, the installation difficulty of the wedge block 114 is reduced and the installation efficiency is improved. At the same time, due to the elastic effect of the connecting plate 119, the entire clamping structure 11 can still maintain good stability and durability when subjected to a certain external force.

[0056] like Figure 2 As shown, in one embodiment, the connecting plate 119 is tilted relative to the base 112, which can reduce the contact area between the connecting plate 119 and the inner wall of the snap-in hole 1182, thereby reducing the wear of the connecting plate 119 and improving durability. It can also reduce the deformation of the inner wall of the snap-in hole 1182 pushing the connecting plate 119, and relatively increase the contact area between the inner wall of the snap-in hole 1182 and the baffle 116, thereby preventing the wedge block 114 from escaping from the snap-in hole 1182 and improving the snap-in stability.

[0057] Exemplarily, the connection plate 119 is inclined at a first preset angle α relative to the base plate, wherein 75°≤α≤89°. Exemplarily, the first preset angle α=75°. In another embodiment, the first preset angle α=85°. In another embodiment, the first preset angle α=89°.

[0058] For example, in one embodiment, a reinforcing rib plate is provided at the connection between the connecting plate 119 and the base 112 to reduce stress concentration between the connecting plate 119 and the base 112; stress concentration is a phenomenon in which when a material is subjected to an external force, stress distribution is uneven due to a sudden change in the local shape or size of the structure, and a high stress state is generated in certain local areas. By adding a reinforcing rib plate, these concentrated stresses can be effectively dispersed to avoid local material damage due to excessive stress. Therefore, the provision of the reinforcing rib plate can not only significantly improve the connection strength of the base 112, but also ensure the stability and safety of the entire structure.

[0059] like Figure 1 As shown, in one embodiment, a matching groove 1122 is provided on one side of the base 112 away from the connecting plate 119. The inner wall of the matching groove 1122 can limit the second preset structure, improve the stability of the clamping connection, and reduce the friction and wear caused by improper matching, thereby further extending the service life of the clamping structure 11.

[0060] like Figure 1 As shown, in one embodiment, the baffle 116 is tilted relative to the base 112 .

[0061] Exemplarily, the baffle 116 is tilted relative to the base 112 at a second preset angle β, wherein 75°≤β≤89°. In one embodiment, the second preset angle β=75°. In another embodiment, the second preset angle β=75°. In another embodiment, the second preset angle β=80°. In yet another embodiment, the second preset angle β=89°.

[0062] like Figure 1 and Figure 2 As shown, in one embodiment, a first guiding bevel 1162 is provided on one end of the baffle 116 away from the base 112. When the baffle 116 begins to approach the engaging hole 1182, the first guiding bevel 1162 can form a natural guiding angle with the edge of the engaging hole 1182. This angle enables the baffle 116 to enter the engaging hole 1182 more easily and smoothly without the need for complicated adjustment or alignment operations. Without this first guiding bevel 1162, the installer may need to spend more time and effort to ensure the alignment and insertion of the baffle 116 with the engaging hole 1182. Now, due to the presence of the first guiding bevel 1162, the installation process becomes simpler and faster.

[0063] like Figure 1As shown, in one embodiment, a second guide slope 1142 is provided on one end of the wedge block 114 away from the base 112. When the wedge block 114 is installed in the snap-in hole 1182, the second guide slope 1142 can abut against the inner wall of the snap-in hole 1182, thereby guiding the wedge block 114 into the snap-in hole 1182, thereby improving the installation efficiency.

[0064] like Figures 4 to 8 As shown, in the second aspect, an embodiment of the present application provides a steering column cover 1, which can be used to isolate a steering wheel rotating column and a cab. The steering column cover 1 includes a first mounting shell 12, a second mounting shell 14 and a snap-on structure 11 as in any of the above embodiments.

[0065] Exemplarily, the first installation housing 12 is the first preset structure, and the second installation housing 14 is the second preset structure. Figure 7 and Figure 8 The first mounting housing 12 and the second mounting housing 14 are shown in a state before being fastened together. After the first mounting housing 12 and the second mounting housing 14 are fastened together, a cavity capable of accommodating a vehicle steering column is formed inside. Figure 4 As shown, after the first mounting shell 12 and the second mounting shell 14 are buckled together, the snap-fit ​​structure 11 enables the first mounting shell 12 and the second mounting shell 14 to be snap-fitted and connected.

[0066] like Figure 6 As shown, the base 112 of the snap-fit ​​structure 11 is fixedly connected to the first mounting shell 12; illustratively, the base 112 is fixedly connected to the first mounting shell 12 by welding, gluing, bolting or integral molding.

[0067] like Figure 5 As shown, the clamping plate 118 of the clamping structure 11 is fixedly connected to the second mounting housing 14, and the first mounting housing 12 and the second mounting housing 14 are clamped and connected through the clamping structure 11. Part of the side wall of the second mounting housing 14 is located in the matching groove 1122 provided on the base 112, and the second mounting housing 14 is limited by the inner wall of the matching groove 1122, thereby improving the stability of the clamping connection.

[0068] Exemplarily, the clamping plate 118 is fixedly connected to the second mounting shell 14 by welding, gluing, bolting or integral molding.

[0069] In this embodiment, the first mounting shell 12 is snap-connected to a second mounting shell 14 via the snap-connecting structure 11. Of course, there is no limit to the number of first mounting shells 12 and second mounting shells 14. For example, the first mounting shell 12 may be snap-connected to more than two second mounting shells 14, the second mounting shell 14 may be snap-connected to more than two first mounting shells 12, or more than two first mounting shells 12 and more than two second mounting shells 14 may be snap-connected to each other.

[0070] In one embodiment, more than two clamping structures 11 are provided. Figure 6 As shown, exemplarily, two clamping structures 11 are provided. For the convenience of description, the two clamping structures 11 are respectively named as the first clamping structure 11 and the second clamping structure 11. The base 112 of the first clamping structure 11 is fixedly mounted on one side of the first mounting shell 12, and the base 112 of the second clamping structure 11 is fixedly mounted on the other side of the first mounting shell 12. Figure 6 As shown, the clamping plate 118 of the first clamping structure 11 is fixedly mounted on one side of the second mounting shell 14 , and the clamping plate 118 of the second clamping structure 11 is fixedly mounted on the other side of the second mounting shell 14 .

[0071] In another embodiment, four clamping structures 11 are provided.

[0072] In a third aspect, an embodiment of the present application provides a vehicle, including a vehicle frame, a steering column assembly, and a steering column cover 1 as described in any of the above embodiments.

[0073] The frame provides the foundation for the rest of the vehicle's components to mount on.

[0074] The steering column assembly is arranged on the vehicle frame. The vehicle frame is provided with a cab and an engine compartment. Part of the structure of the steering column assembly is located in the cab for the convenience of the driver's operation, and another part of the structure of the steering column assembly is located in the engine compartment of the vehicle frame. The remaining part of the steering column assembly is arranged according to the engineering requirements.

[0075] The steering column cover 1 is installed in the cab of the vehicle frame. The first mounting shell 12 and the second mounting shell 14 of the steering column cover 1 are snap-connected to form an accommodating space. The structure of the steering column assembly located in the cab of the vehicle frame is arranged in the accommodating space.

[0076] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0077] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
