[0003] The frame is an important part of street cars. It is not only the skeleton of the whole car, but also carries multiple key functions. Existing frames, such as the motorcycle frame disclosed in the Chinese Patent Library (application number: 03249480.7), include a riser. The key is that: the front support tube, the left front tube, and the right front tube are connected to the riser at one end in a triangular cone frame; the left and right support tubes and the upper support tube are connected to the front support tube and the left and right front tubes in a triangular shape; the other end of the left and right front tubes are respectively connected to the left and right connecting plates and one end of the left and right connecting plate reinforcement plates; the two ends of the upper and lower cross tubes are respectively connected to the left and right connecting plate reinforcement plates; one end of the left and right lower tubes is connected to the front support tube, and the other end is connected to the left and right connecting plates and the left and right connecting plate reinforcement plates.

[0004] In the above frame, the left and right front tubes are connected only by an upper support tube arranged therebetween, which affects the anti-collision performance of the front tubes. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a load-bearing frame in a street car frame, and solves the technical problem of how to improve the front collision capability.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a load-bearing frame in a street car frame comprises two left-right symmetrical frames, the frames comprise a vertically arranged connecting plate and a connecting rod located in front of the connecting plate, the two connecting plates are fixedly connected by a horizontally arranged crossbeam, characterized in that the connecting rod is composed of a front section and a rear section both in the shape of a rod, the rear section is solid and fixedly connected to the upper end of the corresponding connecting plate, the front section is hollow, and the front end of the front section is open; the front section is composed of a front tube portion, a rear tube portion, and an arc tube connecting the front tube portion and the rear tube portion at both ends, the center of the arc tube is between the two connecting rods, and the rear tube portion is arranged obliquely downward; the two front tube portions are arranged in a V-shape, a reinforcing plate is horizontally arranged between the two front tube portions, and the left and right sides of the reinforcing plate are respectively pressed and fixed to the two front tube portions; a rubber body whose shape and size match the inner hole of the front section is arranged in the front section, the rubber body is filled in the front section by injection molding, and an exhaust hole is penetrated through the side wall of the rear tube portion.

[0007] The two front tubes are arranged in a V shape and are both supported forward by an arc tube, which can effectively enhance the self-compressive strength of the front tubes; secondly, a reinforcing plate is provided between the two front tubes to connect the two front tubes more securely, thereby effectively enhancing the compressive performance of the front end of the load-bearing frame and the impact resistance of the front part of the frame to improve safety performance.

The two front tubes are arranged in a V shape and are supported forward by an arc tube, which can effectively enhance the self-compressive strength of the front tubes; secondly, a reinforcing plate is provided between the two front tubes to connect the two front tubes more firmly, thereby effectively enhancing the compressive performance of the front end of the load-bearing frame and enhancing the anti-collision ability of the front part of the frame to improve safety performance.

[0017] 2. Injection molding of a rubber filling body in the front section makes the front end of the connecting rod both rigid and elastic, so as to enhance the compression resistance of the front end of the connecting rod, thereby further enhancing the anti-collision ability of the front part of the frame and improving safety performance.

[0018] 3. The setting of the arc groove can enhance the lateral compressive strength of the arc tube, thereby providing stronger support for the front tube and improving the impact resistance of the front part of the frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] in,

[0027] The two connecting plates 2 are fixedly connected by a horizontally arranged crossbeam 4, and the crossbeam 4 is located between the two connecting plates 2. In actual products, there are two crossbeams 4 and they are arranged in parallel up and down to strengthen the connection strength of the two connecting plates 2.

[0028] like Figure 1 , Figure 3 and Figure 4As shown, the connecting rod 3 is composed of a front section 3a and a rear section 3b, both of which are rod-shaped, and the connecting rod 3 is preferably an integrated structure. Among them, the rear section 3b is solid and fixedly connected to the upper end of the corresponding connecting plate 2; the front section 3a is hollow, and the front end of the front section 3a is open. The front section 3a is composed of a front tube 3a1, a rear tube 3a2, and an arc tube 3a3 whose two ends are respectively connected to the front tube 3a1 and the rear tube 3a2, and the center of the arc tube 3a3 is between the two connecting rods 3; the rear tube 3a2 is arranged obliquely downward; the two front tubes 3a1 are arranged in a V shape, that is, at this time, the distance between the two front tubes 3a1 gradually increases from front to back. A reinforcing plate 5 is horizontally provided between the two front tube portions 3a1, and the left and right sides of the reinforcing plate 5 are respectively pressed and fixed to the two front tube portions 3a1; a rubber body 6 whose shape and size match the inner hole of the front section 3a is provided in the front section 3a, and the rubber body 6 is filled in the front section 3a by injection molding, and an exhaust hole 3a4 is penetrated on the side wall of the rear tube portion 3a2.

[0029] The two front tubes 3a1 are arranged in a V shape and are both supported forward by an arc tube 3a3, which can effectively enhance the self-compressive strength of the front tubes 3a1; secondly, a reinforcing plate 5 is provided between the two front tubes 3a1 to connect the two front tubes 3a1 more securely, thereby effectively enhancing the compressive performance of the front end of the load-bearing frame and the anti-collision ability of the front part of the frame, so as to improve the safety performance.

[0030] At the same time, a rubber body 6 is injection-molded in the front section 3a, so that the front end of the connecting rod 3 has both rigidity and elasticity to enhance the compression resistance of the front end of the connecting rod 3, thereby further enhancing the anti-collision ability of the front part of the frame and improving safety performance.

[0031] In this embodiment,
