Description

Technical Field

[0001] This utility model relates to the field of motorcycle structural design technology, and in particular to a low wind resistance structure for new energy motorcycle frames. Background Technology

[0002] New energy motorcycles feature curved bumpers at the leg area. On one hand, this effectively resists the impact of side collisions or rollovers, reducing direct injury to the rider's legs and improving riding safety. On the other hand, the curved structure has a good airflow guiding effect, which can guide airflow to transition naturally along the vehicle body, reducing turbulence and wind resistance, optimizing the overall aerodynamic performance of the vehicle, and helping to improve range and high-speed stability.

[0003] In the existing technology, the curved bumper of a motorcycle is generally rigidly fixed to the frame. Motorcycles with curved bumpers have difficulty passing through narrow areas, which significantly reduces their maneuverability when traversing narrow passages or complex urban road environments, making them prone to scrapes or jams and affecting traffic efficiency. At the same time, fixed bumpers cannot be retracted or repositioned when not in use, which not only takes up space but also reduces the vehicle's flexibility in urban commuting and is not conducive to adapting to changing usage scenarios and road conditions. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems of existing motorcycles where the curved bumper is generally rigidly fixed to the frame. Motorcycles with curved bumpers have difficulty passing through narrow areas, which significantly reduces their maneuverability when traversing narrow passages or complex urban road environments, making them prone to scraping or getting stuck and affecting traffic efficiency. At the same time, fixed bumpers cannot be retracted or repositioned when not in use, which not only occupies space but also reduces the vehicle's flexibility in urban commuting and is not conducive to adapting to changing usage scenarios and road conditions. Therefore, this utility model proposes a low-drag structure for the frame of a new energy motorcycle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The low wind resistance structure of the new energy motorcycle frame includes a central crossbar and edge folding frames. Edge folding frames are fixedly installed at both ends of the central crossbar. One end of the two edge folding frames is fixedly installed on the side of the central tube. A horizontal frame is installed at the end of the two edge folding frames away from the central tube. The horizontal frame, edge folding frames, and central tube constitute the entire motorcycle frame.

[0007] The edge folding frame is rotatably provided with a docking sleeve on the side near the center tube. A safety frame is fixedly provided on one side of the docking sleeve. Arc-shaped stop bars are equidistantly provided on the side of the safety frame. The safety frame and the arc-shaped stop bars form a structure that protects the rider's legs and reduces wind resistance during riding.

[0008] The bottom of the central crossbar is provided with a retaining and limiting component, which can keep the safety frame in the unfolded or retracted state.

[0009] Optionally, vertical rods are fixedly installed at the bottom of the two horizontal frames, and the bottom ends of the vertical rods are fixedly installed at the top of the edge folding frame.

[0010] Optionally, the retaining and limiting component includes a rectangular block, a limiting fork, a common rod, and a rectangular column, with the rectangular block fixedly disposed at the middle position of the outer wall of the docking sleeve.

[0011] Optionally, a rectangular column is fixedly provided at the middle position of the central crossbar, the rectangular column is movably inserted into the common bar, and limit forks are fixedly provided at both ends of the common bar, the limit forks being movably inserted into the side of the rectangular block.

[0012] Optionally, a blocking block is fixedly provided at the bottom of the rectangular column, and the cross-sectional dimension of the blocking block is larger than that of the common rod.

[0013] Optionally, a reinforcing rod is fixedly provided at one end of the horizontal frame, and the other end of the reinforcing rod is welded to the side of the central cylinder.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The motorcycle frame has rotating docking sleeves on both sides, and arc-shaped safety frames are provided on the sides of the docking sleeves. The inner side of the motorcycle frame is provided with a retaining and limiting component. The retaining and limiting component can keep the two safety frames in the unfolded or retracted state, and can provide stable support when the safety frames are in the unfolded or retracted state, preventing the safety frames from shaking or accidentally rotating during the ride. This not only realizes the foldable function of the safety frames, which makes it easy for the motorcycle to pass flexibly in narrow areas, but also takes into account the lateral protection during use and the storage needs when parking.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 The low wind resistance structure of the new energy motorcycle frame includes a central crossbar 2 and edge folding frames 4. Edge folding frames 4 are fixedly installed at both ends of the central crossbar 2. One end of the two edge folding frames 4 is fixedly installed on the side of the central tube 1. A horizontal frame 5 is installed at the end of the two edge folding frames 4 away from the central tube 1. A reinforcing rod 3 is fixedly installed at one end of the horizontal frame 5. The other end of the reinforcing rod 3 is welded to the side of the central tube 1. The reinforcing rod 3 improves the connection strength between the edge folding frames 4 and the horizontal frame 5.

[0023] The horizontal frame 5, the edge folding frame 4, and the center cylinder 1 constitute the entire motorcycle frame. The horizontal frame 5 serves as the mounting base for the entire motorcycle frame seat. Vertical rods 51 are fixedly installed at the bottom of the two horizontal frames 5. The bottom end of the vertical rods 51 is fixedly installed at the top of the edge folding frame 4. The vertical rods 51 improve the structural strength of the frame composed of the edge folding frame 4 and the horizontal frame 5.

[0024] The edge frame 4 is rotatably mounted with a docking sleeve 14 on the side near the center cylinder 1. A safety frame 11 is fixedly mounted on one side of the docking sleeve 14. Arc-shaped baffles 12 are equidistantly mounted on the side of the safety frame 11. The safety frame 11 and the arc-shaped baffles 12 form a structure that protects the rider's legs and reduces wind resistance during riding.

[0025] A retaining and limiting component is provided at the bottom of the central crossbar 2. The retaining and limiting component can keep the safety frame 11 in the unfolded or retracted state. The retaining and limiting component includes a rectangular block 13, a limiting fork 6, a common bar 7, and a rectangular column 9. A rectangular block 13 is fixedly provided at the middle position of the outer wall of the connecting sleeve 14. A rectangular column 9 is fixedly provided at the middle position of the central crossbar 2. The rectangular column 9 is movably inserted into the common bar 7. Limiting forks 6 are fixedly provided at both ends of the common bar 7. The limiting forks 6 are movably inserted into the side of the rectangular block 13. A blocking block 8 is fixedly provided at the bottom of the rectangular column 9. The cross-sectional dimension of the blocking block 8 is larger than that of the common bar 7. The blocking block 8 allows the common bar 7 to move a certain distance along the outer wall of the rectangular column 9.

[0026] It should be added that the rectangular block 13 is a cube with all edges of equal length. When the rectangular block 13 rotates, the limiting forks 6 can be inserted into the side of the rectangular block 13 to limit its movement.

[0027] The specific implementation steps and principles of this utility model are as follows:

[0028] When the safety frame 11 is in the unfolded state, the limiting fork 6 is inserted into the outer wall of the rectangular block 13. When it is necessary to change the safety frame 11 from the unfolded state to the retracted state, the arc handle 10 is pushed up manually. The arc handle 10 drives the limiting fork 6 to disengage from the rectangular block 13. However, when the two safety frames 11 are rotated to the retracted state and the arc handle 10 is released, the arc handle 10, due to its own weight, drives the two limiting forks 6 to re-insert into the outer wall of the rectangular block 13.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
