[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0039] See Figures 1 to 11 As shown, an electric motorcycle includes a body 1, on which a motor assembly, a front wheel assembly 3, and a rear wheel assembly 4 are mounted. A seat 2 is mounted on the body 1. A mounting cavity 14 is provided in the body 1, with an opening at its upper end. The seat 2 is positioned above the opening and can conceal it. A battery assembly 6 and an electronic control assembly 5 are fixedly mounted in the mounting cavity 14. The battery assembly 6 and the electronic control assembly 5 are electrically connected. A heat dissipation vent 16 is provided at the bottom or side of the mounting cavity 14. The electronic control assembly 5 includes a heat dissipation plate 51 and a circuit board. The heat dissipation plate 51 is... The heat sink 51 is placed on one side of the heat dissipation vent 16 and can be exposed through the heat dissipation vent 16. The circuit board is placed on the side of the heat dissipation vent 16 away from the heat dissipation vent 16. A fixing plate 18 is fixedly installed in the mounting cavity 14. A pressure plate 8 is detachably installed on the fixing plate 18. The electronic control component 5 is placed between the fixing plate 18 and the pressure plate 8. The pressure plate 8 is placed on the side of the circuit board closer to the opening, and the electronic control component 5 is detachably connected to the fixing plate 18. The control system controls the seat cushion 2 to move away from the opening and controls the pressure plate 8 and battery assembly 6 to be disassembled. The circuit board can be exposed through the opening for maintenance.

[0040] The fixed plate 18 and pressure plate 8 in the above structure facilitate the positioning and installation of the electronic control component 5, making it convenient for the assembly and maintenance of the electric motorcycle. When the electric motorcycle is being maintained, the user first controls the seat 2 away from the opening, and the mounting cavity 14 is then exposed. At this time, the user controls the pressure plate 8 and battery component 6 to be disassembled, and then observes and maintains the electronic control component 5 through the opening. This structure facilitates the maintenance of the electric motorcycle, and the user does not need to control the electric motorcycle to be inverted, avoiding damage to the electric motorcycle parts caused by inversion during the maintenance process.

[0041] The seat cushion 2 is rotatably mounted on the vehicle body 1. Controlling the seat cushion 2 to rotate relative to the vehicle body 1 allows the seat cushion 2 to move away from the opening, or it can cover the opening. This structure facilitates user control of the seat cushion 2's movement and maintenance of the battery assembly 6 and electronic control components 5. Preferably, a handle 61 is rotatably mounted on the upper side of the battery assembly 6, allowing the user to lift the battery assembly 6 after disassembly.

The battery assembly 6 abuts against the buffer pad 9, driving the buffer pad 9 to press firmly against the pressure plate 8. The buffer pad 9 not only prevents the battery assembly 6 from impacting the pressure plate 8 and the electronic control component 5 during installation and disassembly, thus avoiding damage to the electronic control component 5 and extending its service life, but also facilitates heat dissipation for both the electronic control component 5 and the battery assembly 6 by spacing them apart, preventing overheating and damage during use.

[0043] The fixing plate 18 is provided with a plurality of support protrusions 181. A receiving space 19 for accommodating the electronic control component 5 is formed between the pressure plate 8 and the fixing plate 18. Fasteners control the pressure plate 8 and the fixing plate 18 to be relatively fixed. The support protrusions 181 can abut against the pressure plate 8 respectively. The setting of the support protrusions 181 can limit the minimum thickness of the receiving space 19, avoid excessive relative force between the pressure plate 8 and the electronic control component 5 during assembly and use, which may cause damage to the electronic control component 5, and help extend the service life of the electronic control component 5. The fixing plate 18 can be detachably set in the mounting cavity 14 by fasteners, or the fixing plate 18 can be fixed in the mounting cavity 14 by welding, riveting, etc.

[0044] In this embodiment, the supporting protrusion 181 is disposed on the side of the electronic control component 5, and the pressure plate 8 extends towards the side of the electronic control component 5 to form a protruding edge 81. The protruding edge 81 is disposed on the side of the supporting protrusion 181 away from the electronic control component 5. Fasteners connect the protruding edge 81 to the supporting protrusion 181, thereby fixing the pressure plate 8 and the fixing plate 18 relative to each other. The provision of the protruding edge 81 facilitates the fixed connection between the pressure plate 8 and the fixing plate 18, which is convenient for the assembly and production of electric motorcycles.

[0045] The battery assembly 6 is positioned on the upper side of the pressure plate 8. The battery assembly 6 drives the pressure plate 8 to press firmly against the electronic control assembly 5, preventing the connection between the pressure plate 8 and the fixing plate 18 from becoming loose. It also controls the seat 2 away from the opening and allows the pressure plate 8 and battery assembly 6 to be disassembled from the mounting cavity 14, exposing the circuit board for maintenance. In this structure, the battery assembly 6 drives the pressure plate 8 to be stably connected to the electronic control assembly 5 and the fixing plate 18, preventing vibrations of the electric motorcycle during use from causing the electronic control assembly 5 to loosen and thus avoiding damage to the electric motorcycle.

[0046] The heat dissipation vent 16 is located on the front side of the vehicle body 1. A first support wall 82 is provided on the pressure plate 8, with the lower end of the first support wall 82 inclined towards the rear side of the vehicle body 1. A second support wall 141 is provided in the mounting cavity 14, with the front side of the second support wall 141 inclined downward. A first abutting wall 62 and a second abutting wall 63 are provided on the battery assembly 6, respectively corresponding to the first support wall 82 and the second support wall 141. The first support wall 82 and the second support wall 141 can support the first abutting wall 62 and the second abutting wall 63, respectively. This structure facilitates the stable installation of the battery assembly 6 and makes it convenient for the installation and replacement of the battery assembly 6. In this utility model, the buffer pad 9 is detachably set on the first support wall 82 by fasteners, or the buffer pad 9 can also be fixed on the first support wall 82 by adhesive.

[0047] In this embodiment, the vehicle body 1 includes a frame 11, with a mounting cavity 14 disposed within the frame 11. Side plates 12 and a bottom plate 13 are respectively provided on both sides and the bottom of the frame 11. Ventilation holes 121 are provided on both the side plates 12 and the bottom plate 13. The ventilation holes 121 facilitate the passage of external air through the mounting cavity 14, promoting heat dissipation for the electronic control components 5 and the battery assembly 6, and preventing overheating and damage to the electronic control components 5 and the battery assembly 6 during use. A front plate 17 is detachably disposed on the front side of the frame 11, with a heat dissipation vent 16 disposed on the front plate 17.

[0048] A fixing member 7 is detachably installed on the vehicle body 1. The fixing member 7 is provided with a clamping groove 71. The side wall of the clamping groove 71 abuts against the battery assembly 6 and drives the first clamping wall 62 and the second clamping wall 63 to abut against the first support wall 82 and the second support wall 141, respectively. This structure facilitates the stable connection between the battery assembly 6 and the vehicle body 1, and makes it convenient for the installation and replacement of the battery assembly 6.

[0049] In this embodiment, the clamping groove 71 is V-shaped, the battery assembly 6 is provided with a V-shaped side ridge 64 that is adapted to the clamping groove 71, and the fastener 7 is provided with connecting feet 72 on both sides. The connecting feet 72 can be fixedly connected to the two sides of the opening by fasteners.

[0050] The vehicle body 1 also includes a motor cavity 15, which is located below the mounting cavity 14. The motor assembly is housed within the motor cavity 15, and the rear wheel assembly 4 is located behind the motor cavity 15. The motor cavity 15 prevents the motor assembly from coming into contact with other objects and causing damage during installation and maintenance. It also reduces the impact of heat generated by the motor assembly on the battery assembly 6 and the electronic control assembly 5 during use, preventing overheating damage to these components. While the motor assembly within the motor cavity 15 is not shown in the accompanying drawings, those skilled in the art can understand its function based on existing technology.

[0051] This application relates to the circuit control section. Controlling the motor assembly to rotate and thus move the electric motorcycle via the electronic control component 5 is a well-known technology in the industry; therefore, this part is not described in detail. The electronic control component 5 is an outsourced part. Based on our functional and installation requirements, we can have the outsourced manufacturer produce the corresponding accessories, which we can then assemble and use. Therefore, although this utility model does not specifically show the structure of the electronic control component 5, those skilled in the art can implement the technical solution of this utility model.

[0052] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
