[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figure 1 As shown, the front frame assembly of this utility model embodiment includes two side tubes 1, a front tube 2, and a reinforcing member 3.

[0029] Two side pipes 1 are arranged opposite each other, and their front ends are connected together. For example, as shown... Figure 1 As shown, both side tubes 1 can be roughly cylindrical in shape. The two side tubes 1 can be arranged opposite each other in the left-right direction, and the two side tubes 1 are roughly mirror-symmetrical. The front ends of the two side tubes 1 can face each other and be connected and fixed. The connection and fixing methods can be welding, integral molding, bonding, etc.

[0030] The head tube 2 is connected to the joint 12 at the front end of the two side tubes 1, and the head tube 2 and the joint 12 are fitted together. For example, as Figure 1 As shown, the docking point 12 is the part where the front ends of the two side tubes 1 meet. The head tube 2 can be arranged vertically. The head tube 2 can be connected and fixed to the docking point 12 by welding. One of the head tube 2 and the docking point 12 can be provided with a recess, and the other can be embedded in the recess, thereby enhancing the limiting and constraint effect of the head tube 2 and the docking point 12.

[0031] The reinforcing member 3 is connected between the two side tubes 1, and is connected to the head tube 2, with the reinforcing member 3 and the head tube 2 being fitted together. For example, as Figure 1 As shown, the reinforcing member 3 can be a plate-like structure. The reinforcing member 3 can generally extend and be arranged along the left and right directions. The left end of the reinforcing member 3 can be connected and fixed to the left side tube 1, and the right end of the reinforcing member 3 can be connected and fixed to the right side tube 1.

[0032] The reinforcing member 3 is also connected and fixed to the head tube 2. Specifically, the reinforcing member 3 can be connected and fixed to the head tube 2 by welding, bonding or other methods. One of the reinforcing member 3 and the head tube 2 may also have a recess, and the other can be fitted into the recess, thereby enhancing the limiting and restraining effect of the reinforcing member 3 and the head tube 2.

[0033] The front frame assembly of this utility model eliminates the design of the main beam tube, allowing any two of the front tube 2, the two side tubes 1, and the reinforcing member 3 to be connected, which ensures the overall connection structure strength while simplifying the overall structure and processing technology.

[0034] In some embodiments, a first groove 13 is provided on the rear side of the docking point 12, and the head tube 2 is located on the rear side of the docking point 12 and embedded in the first groove 13. For example, as Figure 2 As shown, the first groove 13 can be located directly behind the docking point 12. The first groove 13 can extend along the vertical direction and penetrate the docking point 12. The head tube 2 can be a round tube, and the first groove 13 can be a semi-circular groove that matches the shape of the head tube 2.

[0035] During assembly, the head tube 2 can be first embedded in the first groove 13, and then the head tube 2 can be connected to the groove wall of the first groove 13 by welding. This fully ensures the strength and stability of the connection structure between the head tube 2 and the two side tubes 1.

[0036] In some embodiments, each side tube 1 has a groove at its front end, and the grooves of two side tubes 1 are connected and joined together to form a first groove 13. For example, each side tube 1 may have a groove on the rear side of its front end. The groove may be a quarter groove, and the two grooves may be arranged opposite to each other in the left-right direction and connected, thereby facilitating the formation of the first groove 13.

[0037] In some embodiments, each side tube 1 includes a connecting section 11 that bends and extends toward another side tube 1, the connecting sections 11 of the two side tubes 1 are connected together, and the grooves of the two side tubes 1 are respectively provided in the two connecting sections 11.

[0038] For example, such as Figure 2 As shown, a portion of the front end of each side tube 1 can form a connecting segment 11. The connecting segment 11 can be a quarter-circle arc. The connecting segments 11 of each side tube 1 can bend and extend towards each other in the left and right directions, and the ends of the two connecting segments 11 can be joined together. After joining, the two connecting segments 11 together form a half-circle arc structure. The grooves on each side tube 1 can be respectively provided on the two connecting segments 11.

[0039] In some embodiments, the reinforcing member 3 has a second groove 31 in the middle, the second groove 31 is located on the front side of the reinforcing member 3, and the head tube 2 is located on the front side of the reinforcing member 3 and is embedded in the second groove 31.

[0040] For example, such as Figure 2 As shown, the reinforcing member 3 may have a second groove 31 in the middle of its left-right direction. The second groove 31 may also be a semi-circular groove. The second groove 31 can penetrate the reinforcing member 3 in the up-down direction. During assembly, the front tube 2 can first be embedded in the second groove 31 in the direction from front to back, and then it can be connected and fixed to the reinforcing member 3 by welding. This fully ensures the limiting constraint strength of the reinforcing member 3 and the front tube 2.

[0041] In some embodiments, the reinforcing member 3 includes an extension plate 32, which is located on the top side of the reinforcing member 3 and is arranged opposite to the second groove 31 in the vertical direction. The extension plate 32 covers the outer periphery of the head tube 2.

[0042] For example, such as Figure 2 As shown, the extension plate 32 can be integrally formed on the top side of the reinforcing member 3. The extension plate 32 can be in the shape of an arc plate. During assembly, the extension plate 32 can be attached to the outer wall surface of the head tube 2. The connection method can also be welding, bonding, etc. Thus, the extension plate 32 can also enhance the limiting constraint effect on the head tube 2, further ensuring the overall structural stability.

[0043] In some embodiments, the extension plate 32 is provided with a protrusion 321, the extension direction of the protrusion 321 is consistent with the extension direction of the second groove 31, the protrusion 321 protrudes towards the rear side of the extension plate 32 and forms a groove 322 on the front side of the extension plate 32.

[0044] For example, such as Figure 2 As shown, the protrusion 321 can be integrally formed on the extension plate 32. Specifically, the protrusion 321 can be formed by stamping. Both the protrusion 321 and the second groove 31 can generally extend in the vertical direction. This facilitates the simultaneous fitting of the head tube 2 at both the second groove 31 and the extension plate 32.

[0045] The protrusion 321 protrudes towards the rear side of the extension plate 32. The protruding protrusion 321 can form a ridge structure on the rear side of the extension plate 32. The front side of the protrusion 321 is recessed to the rear, which can form a groove 322 extending in the vertical direction. The protrusion 321 can enhance the structural strength of the extension plate 32, thereby ensuring the support effect of the extension plate 32 on the head tube 2.

[0046] In some embodiments, the reinforcing member 3 extends in opposite directions of the two side tubes 1, and the head tube 2 and the reinforcing member 3 are arranged perpendicularly. For example, as Figure 2 As shown, the reinforcing member 3 can extend along the left and right direction, and the front tube 2 can extend roughly along the up and down direction, which helps to ensure the balance of the structural distribution on the left and right sides.
