Description

Technical Field

[0001] This utility model relates to the field of new energy electric vehicle technology, and in particular to a heat dissipation structure for a motor controller. Background Technology

[0002] The motor controller is the energy conversion device on an electric motorcycle. Its main function is to invert the DC power supplied by the battery into three-phase AC power according to driving needs to drive the motor. During the inversion process, the motor controller inevitably generates a lot of heat due to the high-frequency switching of the power transistors and other energy losses.

[0003] To meet their own heat dissipation needs, existing motor controllers typically employ a large-mass aluminum-based heat sink with heat dissipation fins on the outer side to increase the contact area with air. The power transistors are then attached to the inner side of the aluminum-based heat sink. This design utilizes the large heat capacity of the aluminum substrate and the heat exchange with the air to self-cool and reduce the temperature of the power transistors.

[0004] While existing motor controller heat dissipation designs can solve the heat dissipation problem to some extent, the large aluminum substrate design means higher costs, and the heat dissipation efficiency of the aluminum substrate of the motor controller is not high. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation structure for a motor controller, which aims to solve the problems of high cost due to the design of a large aluminum substrate and low heat dissipation efficiency of the aluminum substrate in the motor controller.

[0006] To achieve the above objectives, this utility model provides a heat dissipation structure for a motor controller, including a vehicle frame mounting platform, a mounting positioning frame, thermal grease, a controller aluminum-based mounting plate, and a fixing component. The mounting positioning frame is fixedly connected to the vehicle frame mounting platform and is located on one side of the vehicle frame mounting platform. The thermal grease is disposed on the vehicle frame mounting platform and is located on the side of the vehicle frame mounting platform close to the mounting positioning frame. The controller aluminum-based mounting plate is disposed on the thermal grease and is located on one side of the thermal grease. The fixing component is disposed on the vehicle frame mounting platform.

[0007] The fixing component includes an abutment fixing frame, a rotating frame, a rotating component, and a connecting component. The abutment fixing frame is fixedly connected to the controller aluminum base mounting plate and is located on one side of the controller aluminum base mounting plate. The rotating frame is connected to the vehicle frame mounting platform through the rotating component and abuts against the abutment fixing frame, and is located on the side of the vehicle frame mounting platform close to the abutment fixing frame. The rotating component is disposed on the vehicle frame mounting platform and is connected to the rotating frame. The connecting component is disposed on the vehicle frame mounting platform and is connected to the rotating frame.

[0008] The rotating component includes a support frame and a rotating rod. The support frame is fixedly connected to the vehicle frame mounting platform and is located on one side of the vehicle frame mounting platform. The rotating rod is rotatably connected to the support frame and fixedly connected to the rotating frame, and is located on the side of the support frame closer to the rotating frame.

[0009] The connecting component includes a fixing seat and a fixing bolt. The fixing seat is fixedly connected to the vehicle frame mounting platform and is located on one side of the vehicle frame mounting platform. The fixing bolt is disposed on the fixing seat and is located on the side of the fixing seat closer to the rotating frame.

[0010] The connecting component also includes a washer, which is disposed on the fixing bolt and located on the side of the fixing bolt near the rotating frame.

[0011] This utility model discloses a heat dissipation structure for a motor controller. By utilizing the excellent thermal conductivity and flexibility of the thermally conductive silicone grease, a heat transfer path is established between the motor controller, which is connected to the aluminum-based mounting plate of the controller, and the vehicle frame mounting platform. At the same time, the large heat capacity and large surface area of ​​the vehicle frame mounting platform are used to absorb and conduct heat into the air. This breaks away from the traditional design concept of independent heat dissipation for motor controllers, and organically combines the aluminum-based mounting plate of the controller with the vehicle frame mounting platform, extending the application of the vehicle frame outward, thereby helping to save costs and improve the heat dissipation efficiency of the motor controller.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

Figure 2 This is a structural schematic diagram of the mounting and positioning frame of this utility model. Figure 3 This is a structural schematic diagram of the abutment fixing frame of this utility model. Figure 4 This is a structural schematic diagram of the fixing component of this utility model.

[0020] This utility model provides a heat dissipation structure for a motor controller, including a frame mounting platform 101, a mounting positioning frame 102, thermal grease 103, a controller aluminum base mounting plate 104, and fixing components. The fixing components include an abutment fixing frame 105, a rotating frame 106, a rotating component, and a connecting component. The rotating component includes a support frame 107 and a rotating rod 108. The connecting component includes a fixing seat 109, a fixing bolt 110, and a washer 111. This solution addresses the issue of higher costs associated with larger aluminum substrate designs and the low heat dissipation efficiency of the motor controller's aluminum substrate. It is understood that this solution can be used in situations where heat from the motor controller needs to be transferred to the frame for cooling.

[0021] In this embodiment, the frame mounting platform 101 can be connected to the electric vehicle, and the motor controller can be installed through the controller aluminum base mounting plate 104.

[0022] The mounting positioning bracket 102 is fixedly connected to the vehicle frame mounting platform 101 and is located on one side of the vehicle frame mounting platform 101. The thermally conductive silicone grease 103 is disposed on the vehicle frame mounting platform 101 and is located on the side of the vehicle frame mounting platform 101 close to the mounting positioning bracket 102. The controller aluminum-based mounting plate 104 is disposed on the thermally conductive silicone grease 103 and is located on one side of the thermally conductive silicone grease 103. The fixing component is disposed on the vehicle frame mounting platform 101. The mounting positioning bracket 102 is welded to the vehicle frame mounting platform 101. The thermally conductive silicone grease 103 is disposed on the vehicle frame mounting platform 101. The controller aluminum-based mounting plate 104 is disposed on the thermally conductive silicone grease 103. The mounting positioning bracket 102 can position and install the thermally conductive silicone grease 103 and the controller aluminum-based mounting plate 104 at corresponding positions on the vehicle frame mounting platform 101. The controller aluminum-based mounting plate 104 can be used to install the motor controller. Thermal grease 103 has good thermal conductivity and flexibility, and can serve as a heat transfer path between the motor controller and the frame mounting platform 101. The fixing component is set on the frame mounting platform 101, which can fix the thermal grease 103 and the controller aluminum base mounting plate 104 to the frame mounting platform 101 to prevent displacement or detachment during use. This realizes the heat transfer path between the motor controller and the frame mounting platform 101 by utilizing the good thermal conductivity and flexibility of the thermal grease 103 to connect the controller aluminum base mounting plate 104. At the same time, the large heat capacity and large surface area of ​​the frame mounting platform 101 are used to absorb and conduct heat into the air, thus breaking the traditional design concept of independent heat dissipation of the motor controller. The organic combination of the controller aluminum base mounting plate 104 and the frame mounting platform 101 extends the use of the frame, thereby helping to save costs and improve the heat dissipation efficiency of the motor controller.

[0023] Secondly, the abutment fixing bracket 105 is fixedly connected to the controller aluminum base mounting plate 104 and is located on one side of the controller aluminum base mounting plate 104; the rotating bracket 106 is connected to the vehicle frame mounting platform 101 through the rotating component and abuts against the abutment fixing bracket 105, and is located on the side of the vehicle frame mounting platform 101 close to the abutment fixing bracket 105; the rotating component is disposed on the vehicle frame mounting platform 101 and connected to the rotating bracket 106; the connecting component is disposed on the vehicle frame mounting platform 101 and connected to the rotating bracket 106. There are two abutment fixing brackets 105, and the two abutment fixing brackets 105 are integrally connected and fixed to the controller aluminum base mounting plate 104. The rotating bracket 106 is connected to the vehicle frame mounting platform 101 through the rotating component. The rotating component can connect, support, and limit the rotation of the rotating bracket 106. The rotating component is disposed on the vehicle frame mounting platform 101. The connecting component is located on the vehicle frame mounting platform 101 and connected to one end of the rotating frame 106. The connecting component can connect and fix the other end of the rotating frame 106 to the vehicle frame mounting platform 101, so that the rotation of the rotating frame 106 can be locked when necessary. This allows the operator to fix the thermal grease 103 and the controller aluminum base mounting plate 104 placed on the vehicle frame mounting platform 101 within the mounting positioning frame 102 when it is necessary. The operator rotates the rotating frame 106 to abut against the abutment fixing frame 105 and then uses the connecting component to fix the rotating frame 106 to the vehicle frame mounting platform 101. Thus, the thermal grease 103 and the controller aluminum base mounting plate 104 are abutted and fixed to the vehicle frame mounting platform 101 by the abutment between the rotating frame 106 and the abutment fixing frame 105, preventing them from falling off.

[0024] Meanwhile, the support frame 107 is fixedly connected to the vehicle frame mounting platform 101 and is located on one side of the vehicle frame mounting platform 101; the rotating rod 108 is rotatably connected to the support frame 107 and fixedly connected to the rotating frame 106, and is located on the side of the support frame 107 close to the rotating frame 106. There are two support frames 107, which are welded to the vehicle frame mounting platform 101. There are two rotating rods 108, which are rotatably connected to the corresponding two rotating frames 106. The rotation of the rotating rods 108 can be connected and supported by the support frame 107. The two rotating rods 108 are welded to one end of the rotating frame 106, so that the rotation of the rotating frame 106 can be connected and limited by the rotation of the rotating rods 108.

[0025] In addition, the fixing seat 109 is fixedly connected to the frame mounting platform 101 and is located on one side of the frame mounting platform 101; the fixing bolt 110 is provided on the fixing seat 109 and is located on the side of the fixing seat 109 near the rotating frame 106. The fixing seat 109 is welded to the frame mounting platform 101. The fixing seat 109 has a threaded hole that mates with the fixing bolt 110. By turning the fixing bolt 110 into the fixing seat 109, the other end of the rotating frame 106 can be abutted and fixed to the fixing seat 109 of the frame mounting platform 101.

[0026] Finally, the washer 111 is disposed on the fixing bolt 110 and located on the side of the fixing bolt 110 close to the rotating frame 106. The washer 111 is disposed between the fixed fixing bolt 110 and the rotating frame 106. The washer 111 can prevent the fixing bolt 110 from loosening or falling off the fixing seat 109 in a vibrating environment.

[0027] When using the heat dissipation structure of the motor controller in this embodiment, the good thermal conductivity and flexibility of the thermally conductive silicone grease 103 are used to connect the motor controller on the controller aluminum base mounting plate 104 and the frame mounting platform 101 for heat transfer. At the same time, the large heat capacity and large surface area of ​​the frame mounting platform 101 are used to absorb and conduct heat into the air. This breaks the traditional design concept of independent heat dissipation for motor controllers and organically combines the controller aluminum base mounting plate 104 with the frame mounting platform 101, extending the application of the frame outward, thereby helping to save costs and improve the heat dissipation efficiency of the motor controller.
