Description

Technical Field

[0001] The present application relates to the technical field of electric vehicles, and in particular to an electric vehicle frame. Background Art

[0002] Electric vehicles are a common means of transportation today. The frames of electric vehicles are generally made of iron, and the various parts of the frame are assembled together mainly by welding. In order to reduce weight, the main parts of the frame are mostly made of pipes.

[0003] The existing utility model patent with announcement number CN217753984U discloses an electric vehicle frame, including a head tube, a main beam tube, a flat fork pivot tube and a pivot frame. The head tube is installed at the front end of the main beam tube, the flat fork pivot tube is installed at the tail end of the main beam tube, and the pivot frame is installed on the main beam tube and the flat fork pivot tube. The main beam tube of the utility model extends backward, and the tail end is welded to the flat fork pivot tube and fixed to the pivot frame. The pivot frame is fixed to the main beam tube and the flat fork pivot tube, and the hanging spring column is fixed to the pivot frame to increase the strength of the middle support installation; the seat bucket support tube and the seat bucket cross tube are fixed, and the hanger support tube and the cross tube are fixed.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the front half of the frame is supported by a single main beam tube, which has insufficient strength. When an electric vehicle is hit from the side, it is easy to cause serious deformation of the vehicle body and easily crush the battery, causing more serious accidents. Utility Model Content

[0005] The present application provides an electric vehicle frame, the front side of which has a strong supporting structure. When the electric vehicle is hit from the side, it is not easily deformed, thereby protecting the battery from being squeezed.

[0006] This application provides an electric vehicle frame, which adopts the following technical solutions:

[0007] An electric vehicle frame includes two symmetrically arranged upper beam tubes and two lower beam tubes. A connecting block is fixed to the front ends of the upper beam tubes and the lower beam tubes, and a head tube is fixed to the connecting block. A plurality of reinforcing tubes are fixed between the upper beam tubes and the lower beam tubes. Adjacent reinforcing tubes are fixed by ends, and two adjacent reinforcing tubes are combined with the upper beam tube or the lower beam tube to form a triangular structure.

[0008] By adopting the above technical solution, the upper beam tube and the lower beam tube form a three-dimensional protective support structure. The upper beam tube and the lower beam tube are connected by a reinforcing tube, which greatly enhances the strength and forms a triangular stable structure. The impact resistance and collision resistance of both sides of the frame are good and not easy to deform, thereby protecting the internal objects. The electric vehicle is not easily deformed when hit from the side, protecting the battery from squeezing.

[0009] Optionally, a rear connecting tube is fixed to the rear ends of the upper beam tube and the lower beam tube, and a middle connecting tube is fixed between the middle parts of the two upper beam tubes.

[0010] By adopting the above technical solution, the rear connecting pipe and the middle connecting pipe are connected at the middle position of the frame, so that the positions between the two lower beam tubes and the two upper beam tubes are stabilized.

[0011] Optionally, two side panels are symmetrically fixed to the bottom of the rear connecting pipe, and a plurality of mounting holes are provided on the side panels.

[0012] By adopting the above technical solution, the mounting holes on the side panels can be used for installing the rear fork, as well as the foot support and the motor.

[0013] Optionally, a bottom connecting pipe is fixed between the two side plates, and the bottom connecting pipe is located below the mounting hole.

[0014] By adopting the above technical solution, the bottom connecting pipe is used to connect and fix the bottom positions of the two side panels, thereby strengthening the structure.

[0015] Optionally, a seat tube is fixed to the middle of the upper beam tube, and a seat connecting tube is fixed between the two seat tubes.

[0016] By adopting the above technical solution, after the two seat tubes are covered with the vehicle shell, the top thereof is used to install the vehicle seat cushion, and the two seat tubes are connected and fixed by the seat connecting tube to avoid deformation between the two seat tubes.

[0017] Optionally, a seat support plate is fixed between the two seat tubes, and the seat support plate is an I-shaped structure.

[0018] By adopting the above technical solution, the seat support plate corresponds to the position where the rider sits, and the position is specifically strengthened to improve the supporting effect.

[0019] Optionally, a support tube and a battery support plate are fixed between the two lower beam tubes, and the bottom surface of the battery support plate is in contact with and fixed to the support tube.

[0020] By adopting this technical solution, after the frame covers the vehicle shell, the battery is confined to the battery support plate. The support tube supports the battery support plate, preventing the battery support plate from being concave and deformed due to excessive weight. The support tube also connects and strengthens the lower parts of the two lower beam tubes.

[0021] Optionally, limiting grooves are provided on both sides of the battery support plate, and both ends of the support tube are bent upward and embedded in the limiting grooves.

[0022] By adopting the above technical solution and setting the limiting groove, on the one hand, the battery support plate and the support tube are positioned to avoid the displacement of the installation position of the battery support plate; on the other hand, after the welding is completed, the fixing effect between the support tube and the battery support plate can be significantly enhanced.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The upper beam tube and the lower beam tube form a three-dimensional protective support structure. The upper beam tube and the lower beam tube are connected by reinforcing tubes, which greatly enhances the strength;

[0025] 2. By connecting the upper beam tube and the lower beam tube with a reinforcing tube, a triangular stable structure is formed, which makes the two sides of the frame have good impact resistance and collision resistance, and is not easy to deform, thereby protecting the internal objects.

[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1 and Figure 2 This embodiment discloses an electric vehicle frame, comprising two symmetrically arranged upper beam tubes 1 and two lower beam tubes 2. A connecting block 11 is fixed to the front ends of the upper and lower beam tubes 1 and 2, and a head tube 12 is fixed to the connecting block 11. The two upper beam tubes 1 are bilaterally symmetrical, and the two lower beam tubes 2 are also bilaterally symmetrical. The lower beam tubes 2 are located below the upper beam tubes 1. The upper and lower beam tubes 1 and 2 serve as the main support structures on both sides of the electric vehicle.

[0032] Several reinforcing tubes 3 are fixed between the upper and lower beam tubes 1 and 2. Adjacent reinforcing tubes 3 are fixed at their ends, and two adjacent reinforcing tubes 3 are combined with the upper and lower beam tubes 1 and 2 to form a triangular structure. In this embodiment, there are three reinforcing tubes 3, which are arranged in a direction away from the connecting block 11. Both ends of the reinforcing tubes 3 are fixed by welding. The connection between the upper and lower beam tubes 1 and 2 by the reinforcing tubes 3 significantly enhances strength and forms a stable triangular structure, making both sides of the frame highly impact-resistant and collision-resistant, and less prone to deformation, thereby protecting objects within.

[0033] A rear connecting tube 21 is fixed to the rear ends of the upper and lower beam tubes 1 and a middle connecting tube 13 is fixed in the middle between the two upper beam tubes 1. The rear connecting tube 21 and the middle connecting tube 13 connect the two lower beam tubes 2 and the two upper beam tubes 1 in the middle of the frame, thereby stabilizing the position.

[0034] Two side panels 4 are symmetrically fixed to the bottom of the rear connecting tube 21. These panels are provided with multiple mounting holes 41. By increasing the area of ​​the side panels 4, their load-bearing capacity is increased. The mounting holes 41 on the side panels 4 accommodate the rear fork, kickstand, and motor. A bottom connecting tube 42 is fixed between the two side panels 4, located below the mounting holes 41. This bottom connecting tube 42 connects and secures the bottoms of the two side panels 4, reinforcing the structure.

[0035] A seat tube 5 is fixed to the middle of the upper beam tube 1, and a seat connecting tube 51 is fixed between the two seat tubes 5. After the two seat tubes 5 are covered with the car shell, the top is used to install the car seat cushion, and the two seat tubes 5 are connected and fixed by the seat connecting tube 51 to prevent deformation between the two seat tubes 5.

[0036] A seat support plate 52 is fixed between the two seat tubes 5. The seat support plate 52 is an I-shaped structure. The seat support plate 52 corresponds to the position where the rider sits, and the position is specifically strengthened to improve the support effect.

[0037] Reference Figure 3, a support tube 22 and a battery support plate 6 are fixed between the two lower beam tubes 2, and the bottom surface of the battery support plate 6 is in contact with and fixed to the support tube 22. Limiting grooves 61 are provided on both sides of the battery support plate 6, and the two ends of the support tube 22 are bent upward and embedded in the limiting grooves 61. The battery support plate 6 is a plate for placing batteries. After the frame covers the vehicle shell, the battery is limited on the battery support plate 6. The battery support plate 6 is supported by the support tube 22 to prevent the battery support plate 6 from being concave and deformed due to excessive weight, and the support tube 22 can also connect and strengthen the lower part of the two lower beam tubes 2. By setting the limiting groove 61, on the one hand, the battery support plate 6 and the support tube 22 are positioned to avoid the installation position of the battery support plate 6 from being offset. On the other hand, after welding is completed, the fixing effect between the support tube 22 and the battery support plate 6 can be significantly enhanced.

[0038] The implementation principle of an electric vehicle frame in an embodiment of the present application is as follows: the various structures of the frame are fixed by welding, the upper beam tube 1 and the lower beam tube 2 form a three-dimensional protective support structure, and the upper beam tube 1 and the lower beam tube 2 are connected by a reinforcing tube 3, which greatly enhances the strength and forms a triangular stable structure, so that the impact resistance and collision resistance of both sides of the frame are good and not easy to deform, thereby protecting the internal objects. The electric vehicle is not easily deformed when hit from the side, protecting the battery from squeezing.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
