[0008] As a further improvement of the above solution, bolt holes are respectively opened on the bottom sides of the grooves on both sides, and the bolt holes are located below the No. 1 limiting groove.

[0009] As a further improvement of the above solution, the connecting piece is provided with snap-fits at both side edges of the groove on both sides, and the snap-fits on both sides are symmetrically distributed.

[0010] As a further improvement of the above solution, the connecting piece is made of high-strength steel.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model adopts integrated stamping technology to the connecting piece to achieve the effect of setting reinforcing ribs and groove arch structures on the connecting piece, and uses high-strength steel to achieve the effect of reducing weight while increasing structural strength;

[0013] 2. After weight optimization and structural strengthening, the supporting workpiece of the utility model is compatible with the longitudinal beams of both internal combustion engine and plug-in hybrid vehicles, solving the problem that the current situation where the weight of electric vehicle bodies is generally greater than that of traditional fuel vehicles places higher requirements on the load-bearing capacity of the frame longitudinal beams and their connecting parts.

[0019] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example:

[0021] Please combine Figure 1-Figure 3 In this embodiment, a reinforced support workpiece for the rear channel of a vehicle longitudinal beam includes a connecting piece 1, which is bent as a whole into an arch bridge structure. A groove 5 is provided on the connecting piece 1. Two reinforcing ribs 2 are provided at the arch top of the arch bridge structure of the connecting piece 1. The reinforcing ribs 2 are arranged in a long strip structure.

[0022] Please combine Figure 1As shown, a No. 1 limiting groove 7 and a No. 2 limiting groove 8 are respectively provided on both sides of the arch top of the arch bridge structure of the connecting piece 1. The No. 2 limiting groove 8 is located below the arch top of the arch bridge structure of the connecting piece 1, and the No. 1 limiting groove 7 is located below the No. 2 limiting groove 8, which is mainly used to fix the connection between the connecting piece 1 and the longitudinal beam of the automobile.
