[0021] The following describes the present invention based on embodiments, but the present invention is not limited to these embodiments. Those of ordinary skill in the art should understand that the accompanying drawings provided here are for illustrative purposes only, and the drawings are not necessarily drawn to scale.

[0022] Unless the context clearly requires otherwise, the words "comprising", "including" and similar words throughout the specification and claims should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, the meaning of "including but not limited to".

[0023] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0024] The wheel housing structure provided by the present invention is applicable to a bus frame, and is particularly suitable for use as a wheel housing for a front wheel.

[0025] Specifically, as Figure 1 shown, the wheel housing structure provided by the present invention includes a side plate 100 and a cover plate 200. The side plate 100 is an overall flat plate structure, and the cover plate 200 is an arc-shaped plate. One side edge of the cover plate 200 in the axial direction is connected to the side plate 100. The side plate 100 and the cover plate 200 enclose a receiving space, enabling the wheel to be partially located within the receiving space, and protecting the wheel through the side plate 100 and the cover plate 200. Both the side plate 100 and the cover plate 200 are solid plate structures. Preferably, the thickness of the solid plate structure is 8-10 mm. There are two wheel housing structures provided, and each of the two wheel housing structures corresponds to one wheel. The two wheel housing structures are spaced apart by a certain distance and are simultaneously provided on the frame 300. Preferably, a strengthening structure is provided on the cover plate 200 to improve the overall strength of the wheel housing.

[0026] As Figure 2 shown, the side plate 100 includes a side plate main body 110. The side plate main body 110 is a flat plate structure, including a first part 111 and a second part 112. The first part 111 is a part of a circle, preferably a semi-circular structure, and its arc edge corresponds to the outer edge contour of the wheel. The second part 112 is a rectangular structure, and the straight edge of the first part 111 is connected to the long side of the second part 112. Preferably, the length of the long side of the second part 112 is greater than the length of the straight edge of the first part 111, so that the second part 112 forms extension parts 113 on both sides in its length direction. The extension parts 113 are used to connect to the strengthening structure on the cover plate 200 (detailed below).

[0027] A connecting portion 120 is provided on the second part 112. The connecting portion 120 is connected to the edge of the second part 112 away from the first part 111, and the connecting portion 120 is used to connect to the vehicle frame 300. Preferably, the connecting portion 120 is perpendicularly provided on the second side of the side plate body 110 with respect to the second part 112. The setting of the connecting portion 120 can increase the connection area between the side plate 100 and the vehicle frame 300, thereby improving the reliability of the connection. At the same time, the perpendicular setting of the connecting portion 120 with respect to the second part 112 can also improve the strength of the second part 112 and the side plate 100. Further, the connecting portion 120 is provided along the entire length of the long side of the second part 112, or the connecting portion 120 can be provided at part of the long side of the second part 112.

[0028] An auxiliary mounting portion 130 is provided on the first part 111. The auxiliary mounting portion 130 is formed by extending outward at the arc edge of the first part 111 and is used to connect to a strengthening structure on the cover plate 200 (detailed below). Preferably, the auxiliary mounting portion 130 is a rectangular plate-like structure and is located at a position of the first part 111 away from the second part 112. Further, an included angle is formed between the auxiliary mounting portion 130 and the first part 111, so that the auxiliary mounting portion 130 is inclined toward the side close to the cover plate 200 (i.e., the first side of the side plate body 110) to avoid affecting the space between the two wheel cover structures.

[0029] Preferably, in this embodiment, the first part 111, the second part 112, the connecting portion 120, and the auxiliary mounting portion 130 of the side plate body 110 are integrally formed, and preferably can be formed by operations such as cutting and bending.

[0030] As Figure 1 shown, the cover plate 200 is integrally in an arc-shaped structure. The edge of the arc-shaped structure extends along the arc edge of the first part 111 of the side plate 100 and is connected to the arc edge of the first part 111. Preferably, flat plate structures are formed at both ends of the cover plate 200 in the arc extension direction, and the flat plate structures at both ends are parallelly arranged. Preferably, the flat plate structure is tangent to and connected to the arc, and the flat plate structure is perpendicularly connected to the first side surface of the second part 112.

[0031] The arc-shaped structural part of the cover plate 200 is provided with a first strengthening structure 210, and the first strengthening structure 210 is arranged at a position corresponding to the auxiliary installation part 130 on the first part 111. The first strengthening structure 210 includes a strengthening rod arranged along the axial direction of the cover plate 200, and the strengthening rod is connected to the cover plate 200 and the auxiliary installation part 130. Preferably, the connection part between the strengthening rod and the auxiliary installation part 130 is arranged as an inclined surface, and the inclined surface is in contact connection with the installation part 130. The arrangement of the auxiliary installation part 130 makes the installation of the first strengthening structure 210 more reliable, and enables the first strengthening structure 210 to also strengthen the strength of the side plate 100. As Figure 1 shown in, the inclined arrangement of the auxiliary installation part 130 makes the auxiliary installation part 130 incline towards the direction away from the other wheel cover structure, so as to avoid affecting the structure installed between the two wheel cover structures.

[0032] The flat structural part of the cover plate 200 is provided with a second strengthening structure 220. The second strengthening structure 220 includes a plurality of strengthening rods. The plurality of strengthening rods are simultaneously connected to the cover plate 200, and further, the plurality of strengthening rods can be connected to each other to further improve the strength. A part of the second strengthening structure 220 is connected to the extension part 113 of the second part 112 of the side plate 100, so that the second strengthening structure 220 can also improve the strength of the side plate 100. In this embodiment, the first strengthening structure 210 and the second strengthening structure 220 constitute the strengthening structure on the cover plate 200.

[0033] As Figure 3As shown, in other preferred embodiments, a reinforcing portion is provided on the side plate 100, and the reinforcing portion is used to improve the strength of the side plate body 110. Specifically, in this embodiment, the reinforcing portion includes a reinforcing rod 140, and the reinforcing rod 140 is preferably a cylindrical rod, which is connected to the side plate body 110 by welding to improve its strength. Preferably, a plurality of the reinforcing rods 140 are provided, and the plurality of reinforcing rods 140 are preferably distributed along the edge of the side plate body 110. Further, the reinforcing portion further includes a connecting block 150, and the connecting block 150 is used to connect the reinforcing rod 140 to the side plate body 110. Preferably, at least two connecting blocks 150 are provided, and the two connecting blocks 150 are respectively connected to both ends of the reinforcing rod 140 and then connected to the side plate body 110, so as to form a gap between the reinforcing rod 140 and the side plate body 110. The provision of the connecting block 150 reduces the connection points between the reinforcing rod 140 and the side plate body 110, making it more convenient to connect the reinforcing rod 140 to the side plate body 110, and can further improve the strength of the side plate body 110 without increasing the size of the reinforcing rod 140.

[0034] Preferably, in other preferred embodiments, a reinforcing groove may also be provided on the side plate body 110, and the reinforcing groove constitutes the reinforcing portion. The reinforcing groove is formed on the side plate body 110 by stamping and protrudes toward the first side of the side plate body 100.

[0035] The present invention also provides a frame structure, and the frame structure includes the above-mentioned wheel housing structure, and the wheel housing structure serves as the front wheel housing and / or the rear wheel housing of the frame structure, preferably the front wheel housing. The wheel housing structure is connected to the frame.

[0036] For the wheel housing structure provided by the present invention, the side plate is arranged in a plate-like structure, which occupies less space, makes the space between the two wheel housing structures larger, and thus occupies less space inside the carriage. Moreover, the plate-like structure is convenient for integral formation and does not require welding or connection by other means, saving the processing procedures.

[0037] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0038] It should be understood that the above embodiments are merely exemplary and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions made by those skilled in the art to the above details will all be included within the scope of the claims of the present invention.
