Description

Technical Field

[0002] An electric motorcycle is a type of electric vehicle that uses a battery that stores electricity to provide power to a motor, which then drives the rear wheel of the electric motorcycle to rotate, thereby enabling the electric motorcycle to travel on the road.

[0003] The national standard "General Technical Requirements for Electric Motorcycles and Electric Mopeds" (hereinafter referred to as the "Electric Motorcycle Standard") was issued on June 25, 2009, and came into effect on January 1, 2010. This standard defines two-wheeled or three-wheeled vehicles weighing between 40kg and 400kg, with a maximum design speed greater than 20km / h and less than 50km / h, and powered by electricity as mopeds or electric motorcycles, and classifies electric motorcycles and mopeds as motor vehicles.

[0004] The maximum speed of an electric motorcycle is below 50 km / h. At this speed, the vibration frequency of the electric motorcycle is low, and the requirements for body strength and power battery life are low. Therefore, when the speed of the electric motorcycle is increased to above 50 km / h, the vibration frequency of the electric motorcycle increases, and the requirements for body strength and power battery storage capacity are high.

[0005] In order to meet the requirement that the speed of electric motorcycles can reach above 50 km / h, it is necessary to improve and enhance the body strength of the electric motorcycle and the safety and controllability of the electric motorcycle when traveling at the maximum speed.

[0094] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. In the following description, the front-back direction and the left-right direction correspond to the directions based on the perspective of the rider, and the directions of front, back, left, right, up, and down are described as Figure 1 Directions shown in .

[0095] Figure 1 The present invention is a perspective view of a power battery driven electric motorcycle according to an embodiment of the present invention. Figure 1 It is a three-dimensional image viewed from the back to the front. Figure 2 It is a three-dimensional image of an electric motorcycle viewed from the lower left to the upper right.

[0096] like Figure 1-2 As shown, in some embodiments, an electric motorcycle 10 includes a frame 20, a front wheel 11, a rear wheel 12, a saddle 13, an instrument panel 14, a rear suspension 31, a rear suspension 32, a body panel 40, a motor 50, a power battery 60, a controller 70, a charging device 80, a rear box assembly 90, a braking system 100, a front fairing 43, and a steering system 110, wherein the power battery 60 and the controller 70 are respectively disposed on the frame 20. The power battery 60 provides power to the controller 70 and the motor 50, and the controller 70 controls the operation of the motor 50, thereby driving the rear wheel 12 to rotate. The charging device 80 is disposed on the frame 20 and is connected to the public power grid via wires, thereby converting the AC power of the public power grid into DC power to charge the power battery 60.

[0097] like Figure 1-3 As shown, in some embodiments, the power battery 60, controller 70, and charging device 80 are sequentially arranged on the frame 20 along its height, and the vertical distance from the charging device 80 to the instrument panel 14 is less than the vertical distance from the power battery 60 to the instrument panel 14. The power battery 60, controller 70, and charging device 80 are located on the frame 20 near the front wheel 11. This placement of the power battery 60, controller 70, and charging device 80 on the frame corresponds to the placement of the fuel tank on conventional front-mounted fuel vehicles. This layout results in a compact overall structure for the electric motorcycle 1, with the center of gravity concentrated in the half of the vehicle near the front wheel 14 and a low center of gravity. This allows the electric motorcycle 1 to be stable, safe, and maneuverable at a maximum speed of 120 km / h. Furthermore, while achieving a long range, the motorcycle's size is kept to a minimum, reducing wind resistance and improving maneuverability.

[0098] like Figure 3-7 As shown, in some embodiments, the power battery 60 includes a battery 61 and a battery housing 62. The battery 61 is disposed in the battery housing 62, and the battery housing 62 is connected to the frame 20. The battery housing 62 enhances the strength of the frame 20 and improves the robustness of the electric motorcycle.

[0099] like Figure 6-7 As shown, in some embodiments, the battery housing 62 includes a shell 621 and side panels 622, which are fixed to the shell 621 by screws. The side panels 622 are provided with a plurality of ribs 6221. The ribs 6221 increase the surface area of ​​the battery housing 62, improving the heat dissipation of the power battery 60; they also enhance the strength of the battery housing 62, improving the safety of the electric motorcycle.

[0100] like Figure 6-7 As shown, in some embodiments, the bottom of the housing 621 is provided with multiple protrusions 6211. In this embodiment, there are three protrusions 6211. A pad 6212 is provided between two adjacent protrusions 6211, with the end surface of the pad 6212 being flush with the end surface of the protrusion 6211, and the pad 6212 is provided with multiple recessed holes. The battery 61 is disposed within the housing 621, supported by the protrusions 6211 and the pad 6212.

[0101] like Figure 1-2 As shown, in some embodiments, the electric motorcycle 1 is provided with a cooling duct 63 associated with the power battery 60. The cooling duct 63 is a channel formed around the power battery 60 and a gap formed between the body cover 40 and the power battery 60. The cooling duct quickly dissipates heat from the power battery, keeping the power battery operating temperature within a preset range when the electric motorcycle is running at high speed, reducing battery power loss, and ensuring the safety of the electric motorcycle during driving and the endurance of the electric motorcycle.

[0102] In addition, if Figure 8-9As shown, in other embodiments, the power battery 60 can also be cooled by a heat sink 71a. Water cooling can ensure rapid cooling of the power battery 60 at high temperatures, ensuring normal and efficient operation of the power battery 60. The heat sink 71a includes a water tank 711a, a heat pipe 712a connected to the water tank 711a, and a water pump 713a connected to the heat pipe 712a. The heat pipe 712a is partially disposed on the power battery 60. Specifically, the heat pipe 712a includes a first branch 7121a, a second branch 7122a, and a third branch 7123a. One end of the first branch 7121a is connected to the liquid outlet of the water tank 711a, and the other end is connected to the liquid inlet of the water pump 713a. One end of the second branch 7122a is connected to the liquid outlet of the water pump 713a, and the other end is connected to the liquid inlet of the power battery 60. The third branch 7123a is connected to the liquid outlet of the power battery 60 , and the other end is connected to the return end of the water tank 711a , and a portion of the third branch 7123a is fixed on the power battery 60 .

[0103] like Figure 8-9 As shown, a heat sink 7112a is provided on the side wall of the water tank 711a. The heat sink 7112a increases the contact area between the battery shell and the air, thereby improving the heat dissipation effect.

[0104] like Figure 8-9 As shown, the heat dissipation device 71a further includes a cooling fan 7113a, which is disposed on one side of the water tank 711a. A fan bracket 7114a is fixed to the water tank 711a via screws, and the cooling fan 7113a is disposed on the fan bracket 7114a. The air inlet of the cooling fan 7113a faces the saddle 13, and the air outlet of the cooling fan 7113a faces the instrument panel 14. Therefore, when the cooling fan 7113a is in operation, the airflow generated by the cooling fan 7113a blows toward the water tank 711a, thereby efficiently dissipating heat from the water tank 711a and maintaining a low temperature for the coolant within the water tank 711a. This effectively cools the power battery 60, ensuring the safety of the electric motorcycle 1 during high-speed travel.

[0105] like Figure 8-9 As shown, the heat dissipation device 71a also includes a sub-tank 714a disposed on the vehicle frame 20. A liquid delivery pipe 7144a is connected to the sub-tank 714a, which is in communication with the water storage tank 711a. As the amount of coolant in the water storage tank 711a decreases, a negative pressure forms within the water storage tank 711a. The coolant in the sub-tank 714a is then transported to the water storage tank 711a via the liquid delivery pipe under the negative pressure of the water storage tank 711a. The sub-tank 714a maintains the coolant content in the water storage tank 711a, maintaining the coolant's cooling performance on the power battery 60 and ensuring the safety of the electric motorcycle 1 during driving.

[0106] like Figure 6As shown, in some embodiments, the controller 70 is located between the charging device 80 and the power battery 60. The controller is provided with a wire connector, which is connected to the motor via a cable. The controller 70 is mounted on the battery housing 62, and is located at the end of the battery housing 62 near the instrument panel 14. The battery housing 62 is provided with a mounting position 623, which is provided with a groove. The controller 70 is mounted on the mounting position 623 and is fixed to the battery housing 62 by screws.

[0107] like Figure 10-11 As shown, in some embodiments, a cooling device 71b is provided on the vehicle frame 20 and is associated with the controller 70. The cooling device 71b includes a cooling tank 711b, a coolant pipe 712b connected to the cooling tank 711b, and a pump body 713b connected to the coolant pipe 712b. The coolant in the coolant pipe 712b flows through the controller 70. The coolant pipe 712b includes a first branch pipe 7121b, a second branch pipe 7122b, and a third branch pipe 7123b. One end of the first branch pipe 7121b is connected to the liquid outlet of the cooling tank 711b, and the other end is connected to the liquid inlet of the pump body 713b. One end of the second branch pipe 7122b is connected to the liquid outlet of the pump body 713b, and the other end is connected to the liquid inlet of the controller 70. The third branch pipe 7123 b is connected to the liquid outlet end of the controller 70 , and the other end is connected to the return end of the cooling box 711 b , and a portion of the third branch pipe 7123 b is fixed on the power battery 60 .

[0108] like Figure 10-11 As shown, the sidewalls of the cooling box 711b are also provided with heat sinks 7112b and cooling fans 7113b. Multiple heat sinks 7112b are provided on the sidewalls of the cooling box 711b. The cooling fan 7113b corresponds to the cooling box 711b and is located on one side of the heat sink 7112b. It is mounted on the cooling box 711b via a fan bracket 7114b, cooling the cooling box 711b and improving the heat dissipation efficiency of the heat sink 7112b. The air inlet of the cooling fan 7113b faces the saddle 13, and the air outlet faces the instrument panel 14. When the cooling fan 7113b is activated, the generated airflow flows from the side closest to the saddle 13 to the side away from the saddle 13, thereby preventing hot air from directly blowing onto the driver.

[0109] like Figure 10-11As shown, the cooling device 71b also includes a sub-tank 714b disposed on the vehicle frame 20. A liquid delivery pipe 7144b is connected to the sub-tank 714b, which is in communication with the cooling box 711b. As the amount of coolant in the cooling box 711b decreases, a negative pressure forms in the cooling box 711b. The coolant in the sub-tank 714b is then transported to the cooling box 711b via the liquid delivery pipe under the negative pressure of the cooling box 711b. The sub-tank 714b maintains the coolant content in the cooling box 711b unchanged, maintaining the coolant's cooling performance on the power battery 60 and ensuring the safety of the electric motorcycle 1 during driving.

[0110] In addition, if Figure 10-11 As shown, in other embodiments, the coolant in the coolant pipe 712 b also flows through the power battery 60 .

[0111] In addition, if Figure 12 As shown, in other embodiments, a cooling fan 72 is provided on the vehicle frame 20. The air inlet of the cooling fan 72 is directed toward the rear wheel 12, and the air outlet of the cooling fan 72 is directed toward the front wheel 11 and blows toward the controller 70. The cooling fan 72 cools the controller 70 with air, and the air inlet is directed toward the rear wheel 12, so that the airflow flows toward the front wheel 11, preventing the hot air from blowing directly onto the driver.

[0112] like Figure 13-15 As shown, in some embodiments, the charging device 80 is provided on the vehicle frame 20, and the charging device 80 is located on the portion of the vehicle frame 20 near the saddle 13. The charging device 80 is provided with a charging connector 81, which faces the direction opposite to the front fairing 141.
