Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of motorcycles, and in particular to a crossbeam triangular reinforcement structure. Background Technology
[0002] Electric motorcycles are a type of electric vehicle that uses a battery to power an electric motor. The electric drive and control system consists of a drive motor, a power supply, and a speed control device for the motor. Other components of an electric motorcycle are basically the same as those of an internal combustion engine motorcycle. They are classified into electric mopeds and electric motorcycles based on their maximum speed or motor power.
[0003] An electric motorcycle consists of: an electric drive and control system, a mechanical system including drive transmission, and a work device to perform a specific task. The electric drive and control system is the core of an electric motorcycle and the biggest difference between it and a vehicle powered by an internal combustion engine.
[0004] Most existing electric motorcycles are modified from motorcycles. In order to accommodate the battery pack of the electric motorcycle, the frame needs to be redesigned to ensure the installation structure of the battery pack. However, the modified frame has lower strength, which affects the normal operation of the motorcycle. Utility Model Content
[0005] Purpose of the invention: The purpose of this utility model is to provide a crossbeam triangular reinforcement structure to solve the problem that the existing motorcycle frame is not strong enough and is prone to deformation when installing battery packs, etc.
[0006] Technical solution:
[0007] A crossbeam triangular reinforcement structure includes a main frame, which is inclined and connected to a horizontally arranged crossbeam. A strength bar connects the crossbeam and the main frame. The strength bar, the crossbeam, and the main frame are located in the same plane. A triangular plate is fixedly installed between the strength bar, the crossbeam, and the main frame.
[0008] Furthermore, the triangular plate has a chamfered edge on its periphery, and the chamfered edge is connected to the strength bar, the crossbeam frame, and the main frame.
[0009] Furthermore, the triangular plate, the strength bar, the crossbeam frame, and the main frame are all connected by welding.
[0010] Furthermore, the three corners of the triangular plate are chamfered.
[0011] Furthermore, the main frame is provided in pairs, and the two main frames are fixedly connected at one end away from the crossbeam frame.
[0012] Furthermore, a base frame is fixedly connected to the main frame below the crossbeam frame.
[0013] Furthermore, the triangular plate is provided with a through connecting window, and the triangular plate is provided with several connecting holes around the connecting window.
[0014] Furthermore, several connecting rods connect the two strength rods.
[0015] Beneficial effects: The main frame and crossbeam are connected by strength bars to form a triangular structure, thereby improving the overall strength of the frame. At the same time, triangular plates are installed at the gaps between the triangles to connect the strength bars, main frame and crossbeam, thereby further improving the connection strength and ensuring the overall strength of the frame.

[0018] Figure 3 This is a schematic diagram of the internal structure of the vehicle frame of this utility model. Detailed Implementation
[0019] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] Example 1
[0021] like Figure 1 As shown, a crossbeam triangular reinforcement structure includes a main frame 11, which is the main front structure of the vehicle frame. There are two main frames 11, and one end of the two main frames 11 is fixedly connected. The fixed connection point of the two main frames 11 is the head section.
[0022] Both main frames 11 are arc-shaped, and a U-shape can be formed between the two main frames 11. Both main frames 11 are connected to crossbeams 12. The main frames 11 and crossbeams 12 form a frame structure. The interior of the frame structure can be used to install battery packs, etc.
[0023] The lower end of the main frame 11 is provided with a base frame 18, which is fixedly connected to both main frames 11. The base frame 18 is used to support the main frames 11 upwards.
[0024] To facilitate installation and connection, the main frame 11 is tilted, with the head of the main frame 11 located at the top. The crossbeam 12 is connected to the middle of the main frame 11, and the crossbeam 12 is kept horizontal. A seat cushion or similar item can be connected to the crossbeam 12.
[0025] The two crossbeams 12 are connected together at the ends away from the main frame 11 by a circular arc tube to improve the connection strength.
[0026] To ensure support strength, a strength rod 13 is connected between the crossbeam frame 12 and the main frame 11. The two ends of the strength rod 13 are connected to the middle of the crossbeam frame 12 and the main frame 11, respectively. The strength rod 13 supports and connects the crossbeam frame 12 and the main frame 11, and can prevent the crossbeam frame 12 from collapsing.
[0027] Meanwhile, the crossbeam frame 12, the main frame 11, and the strength bar 13 are all connected by welding to ensure the connection strength.
[0028] like Figure 3 As shown, several connecting rods 19 are connected between the two strength rods 13. In this application, there are three connecting rods 19, which are arranged in parallel. The connecting rods 19 support the strength rods 13 on both sides, thereby forming the internal space of the vehicle frame with the main frame 11 and the crossbeam frame 12, which facilitates the installation of battery packs and other structures.
[0029] The crossbeam frame 12, the main frame 11, and the strength bar 13 are located in the same plane, and the crossbeam frame 12, the main frame 11, and the strength bar 13 are combined to form a triangular structure, thereby ensuring the strength of the main body of the vehicle frame and facilitating passenger access and the installation of the motor and battery.
[0030] like Figure 2 As shown, there is a gap between the crossbeam frame 12, the main frame 11, and the strength rod 13. The gap is triangular, and a triangular plate 14 is installed in the gap. The triangular plate 14 is fixedly connected to the crossbeam frame 12, the main frame 11, and the strength rod 13. Furthermore, the triangular plate 14 is connected to the crossbeam frame 12, the main frame 11, and the strength rod 13 by welding, which improves the stability of the triangular structure between the crossbeam frame 12, the main frame 11, and the strength rod 13.
[0031] The three sides of the triangle plate 14 are provided with chamfered edges 15. The chamfered edges 15 are bent toward the other triangle plate 14. The chamfered edges 15 can increase the connection area between the triangle plate 14 and the crossbeam frame 12, the main frame 11, and the strength bar 13, thereby improving the connection strength and increasing the aesthetics of the triangle plate installation.
[0032] The three corners of the triangle plate 14 are provided with chamfers 16. The chamfers 16 reduce the welding difficulty of the triangle plate 14 and reduce the stress deformation caused by the contact at the corners.
[0033] The center of the triangular plate 14 is provided with a through connecting window 17, which can be used to connect to the structure located inside the frame, thereby improving the connection effect.
[0034] Meanwhile, the triangular plate 14 has several through threaded holes 18 on the periphery of the connecting window 17, through which other structures are connected.
[0035] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
