[0034] The utility model provides a motor controller 100 .

[0035] See also Figures 1 to 4 In one embodiment of the utility model, the motor controller 100 includes a shell 1, a circuit board 2, a control module 3 and a power module 4. The shell 1 has a cavity formed inside; the circuit board 2 is accommodated in the cavity; the control module 3 is arranged on one side of the circuit board 2 and is electrically connected to the circuit board 2, and the control module 3 includes a first function switch 31 and a second function switch 32; the power module 4 is arranged on a side of the circuit board 2 away from the control module 3, and the power module 4 is electrically connected to the circuit board 2.

[0036] The technical solution of the utility model is to arrange a circuit board 2 in a housing 1, and arrange a control module 3 and a power module 4 on both sides of the circuit board 2 and electrically connected thereto. The control module 3 includes a first function switch 31 and a second function switch 32. The first function switch 31 and the second function switch 32 can be configured into different circuit paths to achieve switching of different functions. For example, the motor can be connected to different power supplies, control signals or different branches in the circuit through these two switches, thereby changing the operation mode or speed of the motor. In this way, the function can be changed without changing the internal program or connecting to the electronic speed regulator through a programming tool (such as a programming box), which is simple to operate and easy to use.

[0037] In one embodiment of the present application, the first function switch 31 is an active freewheeling switch, that is, the first function switch 31 is used to turn on or off the active freewheeling function (ASCF). If it is turned on, it can effectively slow down the temperature rise of the motor controller 100; in another embodiment of the present application, the second function switch 32 is a motor steering switch, that is, the second function switch 32 is used to switch the forward and reverse rotation of the motor. This function can avoid the need to re-weld or plug and unplug the motor wire when the user's motor steering is wrong. Of course, the active freewheeling switch and the motor steering switch can also be set at the same time. If necessary, the above-mentioned first function switch 31 and the second function switch 32 can also be defined as switches for other functions, not limited to realizing active freewheeling or motor steering.

[0038] In order to facilitate the user to operate the first function switch 31 and the second function switch 32, in one embodiment of the present application, the housing 1 includes a first shell 11 and a second shell 12, the first shell 11 is connected to the second shell 12 to form a cavity, and the first shell 11 is provided with a first opening 111 and a second opening 112 connected to the cavity; the first function switch 31 and the second function switch 32 are exposed to the outside of the housing 1 through the first opening 111 and the second opening 112 respectively. In this way, the control of different functions of the motor can be achieved without disassembling the housing 1. In addition, a number of supporting ribs are designed inside the first shell 11 and the second shell 12, which can fix the circuit board from moving inside on the one hand, and can also play a role in supporting and strengthening the structural strength on the other hand.

[0039] In one embodiment of the present application, a heat dissipation slot 121 communicating with the cavity is provided on the side of the second housing 12 facing away from the first housing 11; the housing 1 further includes a heat dissipation cover 14, which is connected to the first housing 11 to cover the notch of the heat dissipation slot 121. By providing the heat dissipation slot 121 on the side of the second housing 12 facing away from the first housing 11 and installing the heat dissipation cover 14, the heat dissipation surface area of ​​the motor controller 100 can be increased, and the heat dissipation efficiency can be improved. In addition, the connection and covering of the heat dissipation cover 14 can also help prevent dust and other debris from entering the heat dissipation slot 121, and may provide additional protection and aesthetic effects.

[0040] In one embodiment of the present application, a boss 141 is formed on one side of the heat dissipation cover 14 close to the first housing 11, and the boss 141 extends into the cavity through the notch of the heat dissipation slot 121 to abut against the power module 4. The design of the boss 141 may help ensure effective contact between the heat dissipation cover 14 and the power module 4, thereby promoting the heat dissipation effect. Through the extension of the boss 141, the heat dissipation resistance can be minimized, so that the heat can be more effectively conducted to the heat dissipation cover 14 and then dissipated to the external environment. This close contact may help improve the heat dissipation efficiency and ensure the stability and reliability of the motor controller 100 under high load.

[0041] Furthermore, in an embodiment of the present application, the boss 141 is bonded to the power module 4 by thermally conductive silicone. By using thermally conductive silicone for bonding, the heat conduction efficiency between the boss 141 and the power module 4 can be effectively improved. The thermally conductive silicone has good thermal conductivity. On the one hand, it can help heat to be more effectively transferred from the power module 4 to the heat dissipation cover 14. On the other hand, it can also ensure good contact between the boss 141 and the power module 4 and minimize thermal resistance, thereby improving the heat dissipation effect.

[0042] In one embodiment of the present application, a plurality of heat dissipation protrusions 142 are formed at intervals on the side of the heat dissipation cover 14 facing away from the first shell 11; by forming the heat dissipation protrusions 142 on the side of the heat dissipation cover 14 facing away from the first shell 11, the heat dissipation surface can be increased, making it easier for heat to be conducted away from the motor controller 100, thereby effectively increasing the heat exchange between the heat dissipation cover 14 and the surrounding environment, thereby helping the motor controller 100 to maintain operation within a suitable temperature range.

[0043] In one embodiment of the present application, the material of the heat dissipation cover 14 is aluminum alloy. Aluminum alloy is a common heat dissipation material, which is widely used in the manufacture of heat dissipation housings due to its good thermal conductivity and lightweight characteristics. Aluminum alloy has excellent thermal conductivity and can effectively transfer heat from the inside to the external surface, thereby promoting heat dissipation. In addition, the lightweight characteristics of aluminum alloy make the heat dissipation housing relatively light, which helps to reduce the weight of the entire motor controller 100 while maintaining structural strength and durability.

[0044] In one embodiment of the present application, the side of the heat dissipation cover 14 facing away from the first housing 11 is at the same level as the side of the second cover facing away from the first housing 11. After the heat dissipation cover 14 is assembled, it is flush with the top surface of the second cover, which improves the aesthetics and integrity and greatly reduces the thickness of the entire motor controller 100.

[0045] In order to facilitate the assembly and connection of the first shell 11 and the second shell 12, in one embodiment of the present application, the housing 1 further includes a snap-fit ​​structure 13, which includes a fastener 131 and a snap-fit ​​groove 132. One of the fastener 131 and the snap-fit ​​groove 132 is provided on the first shell 11, and the other is provided on the second shell 12. The fastener 131 is snap-fitted into the snap-fit ​​groove 132, so that the first shell 11 and the second shell 12 are connected as a whole. Here, the fastener 131 can be understood as a snap or a hook. Specifically, the upper shell and the lower shell are designed to be plastic parts. The first shell 11 is designed with four snap-fit ​​grooves 132 on both sides of the long side, and the second shell 12 is designed with hooks at corresponding positions. The first shell 11 and the second shell 12 are combined into a whole through the hooks, without the need for screw fastening, which simplifies the assembly process, can provide a reliable connection, and makes the housing 1 easier to disassemble and reassemble.

[0046] In one embodiment of the present application, an extension protection portion 15 is provided at one end of the housing 1, and the extension protection portion 15 is provided with a through hole connected to the cavity; the motor controller 100 also includes a filter capacitor 5 electrically connected to the circuit board 2, and the extended portion of the filter capacitor 5 extends out of the cavity through the through hole. The extension protection portion 15 can wrap and protect the extended portion of the filter capacitor 5, and will not be damaged by long-term vibration of the motor during use. Generally speaking, a power line, a throttle signal line, and a filter capacitor 5 are designed at one end of the circuit board 2; a motor connection line is designed at the other end, and the power line, the throttle signal line, the filter capacitor 5, and the motor connection line all extend out of the housing 1 to connect with other components.
