[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 4 As shown, the support frame for the middle of the rear bumper of this utility model includes an annular frame 1, a connecting plate 2, and an intermediate mounting body 3. The connecting plate 2 is annular and located inside and fixed to the annular frame 1. The connecting plate 2 and the annular frame 1 are integrally formed, for example, by injection molding. The intermediate mounting body 3 is fixed to the connecting plate 2. The intermediate mounting body 3 and the connecting plate 2 are preferably integrally formed by injection molding. After the intermediate mounting body 3 protrudes from the connecting plate 2, an annular groove 12 is formed between the intermediate mounting body 3 and the annular frame 1. This not only helps to save materials and reduce production costs, but also provides clearance space for the annular frame 1 or the intermediate mounting body 3 when the support frame is subjected to compressive force, so that the annular frame 1 or the intermediate mounting body 3 is not damaged under appropriate deformation.

[0024] In the embodiment, the elastic pressing assembly comprises an L-shaped elastic pressing plate 6, one end of the elastic pressing plate 6 is fixed to the annular frame 1, the other end of the elastic pressing plate 6 is a free end, and a space 6a for deformation of the elastic pressing plate 6 is arranged between the elastic pressing plate 6 and the annular frame 1. The elastic pressing assembly is arranged on the upper portion of the annular frame 1. After the support frame is fixed to the vehicle frame, the elastic pressing assembly is limited by the trunk frame. When the flange of the bumper (not shown in the figure) is inserted into the space 6a, the flange of the bumper is pressed tightly by the pressure generated by the elastic pressing plate 6. The elastic pressing plate 6 is provided with a first through hole 7, and the surface of the elastic pressing plate 6 facing the annular frame 1 is provided with a protruding tooth 8. The inner wall surface of the flange of the bumper is provided with a buckling part, the buckling part is buckled with the protruding tooth 8, so that the buckling part on the bumper is fixed with the elastic pressing plate 6 as a whole, and the flange of the bumper is pressed tightly by the elastic pressing plate 6, so that the bumper and the bumper support are combined firmly.

[0025] The lower portion of the annular frame 1 is provided with an extension 5 for cooperation with the vehicle frame, and the extension 5 supports the support frame. The middle mounting body 3 is provided with a mounting hole 4 for mounting the support frame. In the embodiment, the middle mounting body 3 is provided with a boss 3a, and the mounting hole 4 passes through the boss 3a. The boss 3a is used for cooperation with a fitting groove on the vehicle frame, and a threaded hole is arranged in the fitting groove. A screw is used to threadedly connect the mounting hole 4 with the threaded hole on the vehicle frame, so that the middle mounting body 3 is pressed on the vehicle frame, thereby fixing the support frame.

[0026] The middle mounting body 3 is further provided with a plug-in assembly for preventing reverse installation. The plug-in assembly comprises a plug pin 9 and a spring buckle 10. One end of the plug pin 9 is fixed to the middle mounting body 3, and the other end of the plug pin 9 is a free end. The plug pin 9 has a hollow part, and a notch is arranged on the side wall of the plug pin 9 and cooperates with the hollow part. The spring buckle 10 cooperates with the notch on the plug pin 9. One end of the spring buckle 10 is fixed to the plug pin 9, and the other end of the spring buckle 10 is a free end. The spring buckle 10 is inclined, and at least a part of the spring buckle 10 protrudes from the peripheral surface of the plug pin 9. A plug-in hole is arranged on the vehicle frame. During the process that the plug pin 9 is inserted into the plug-in hole on the vehicle frame, the spring buckle 10 is extruded by the hole wall of the plug-in hole, so that the spring buckle 10 is retracted into the hollow part on the plug pin 9. Due to the restoring force of the spring buckle 10, the spring buckle 10 is tightly fitted with the hole wall of the plug-in hole. In the utility model, only after the plug-in assembly is cooperated with the plug-in hole on the vehicle frame, the whole support frame can be fitted with the vehicle frame. Therefore, the structure avoids the problem of reverse installation of the support frame during installation, and ensures correct installation of the support frame through the effect of the plug-in assembly.

[0027] Also included are a plurality of connecting ribs 11, which are located within the ring-shaped frame 1 and distributed around the mounting body 3, one end of the connecting rib 11 being fixed to the ring-shaped frame 1, and the other end being fixed to the intermediate mounting body 3, and through the action of the connecting rib 11, the overall strength of the product is increased.

[0028] In this embodiment, preferably, a reinforcing rib 13 is arranged on the outer surface of the ring-shaped frame 1, and the reinforcing rib 13 is integrally formed with the ring-shaped frame 1, and through the action of the reinforcing rib 13, the overall strength of the product is increased.

[0029] In the utility model, the support frame is installed at the rear middle part of the rear end of the frame, the rear bumper middle part is supported by the support frame, and large gaps between the bumper and other parts are avoided. After the plug-in assembly is set, the support frame can be attached to the frame only after the plug-in assembly is matched with the plug-in hole on the frame, thus, the structure avoids the problem of installing the support frame in reverse, and the correct installation of the support frame is ensured through the action of the plug-in assembly.
