Description

Technical Field

[0001] The utility model relates to a heat dissipation structure of an electric scooter controller, and more specifically, to a heat dissipation structure of an electric scooter controller with good heat dissipation performance and simple structure. Background Art

[0002] The controller is used to control the speed, brakes and lighting of the electric scooter. The controller and battery are usually installed in the pedal assembly of the electric scooter. For waterproof and dustproof reasons, the controller is enclosed in the pedal assembly, which limits its heat dissipation and affects the operating efficiency of the controller itself and the normal operation of surrounding electrical components. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a heat dissipation structure of an electric scooter controller with good heat dissipation performance and simple structure.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat dissipation structure of an electric scooter controller, comprising a controller, the controller comprising a circuit board, a MOS tube arranged on one side of the circuit board, and a shell sleeved outside the circuit board, the shell is provided with an embedding groove and a "7"-shaped fixing piece arranged in the embedding groove, when the circuit board is installed in the shell, one side of the "7"-shaped fixing piece is pressed into the embedding groove by an external force, so that the other side of the "7"-shaped fixing piece forms an extrusion on the MOS tube, thereby causing the "7"-shaped fixing piece to contact the MOS tube, so that the circuit board is fixed in the shell.

[0005] By adopting the above technical solution, when the circuit board is installed in the shell, the "7"-shaped fixing part is squeezed onto the MOS tube through the pressure of external force, forming a certain pressure, which can effectively reduce the shaking and loosening of the circuit board during movement or vibration. This fixing method can ensure the stability and reliability of the controller and reduce the risk of failure caused by external impact or vibration.

[0006] The utility model is further configured as follows: the "7"-shaped fixing piece includes an interfering side and an inserting side, an interfering step is provided on the inner wall of one side of the embedding groove, and when the "7"-shaped fixing piece is pressed into the embedding groove, the corner of the "7"-shaped fixing piece interferes with the interfering step, so that the "7"-shaped fixing piece fixes the circuit board.

[0007] By adopting the above technical solution, the installation and removal of the circuit board are more convenient and quick. When maintenance or replacement of the circuit board is required, the circuit board can be easily taken out or installed by simply removing the fixing parts, thereby improving the efficiency of disassembly and maintenance.

[0008] The utility model is further configured as follows: the corners of the "7"-shaped fixing member form an acute angle, and the acute angle is approximately between.

[0009] By adopting the above technical solution, the angle between about 70° and 90° increases the squeezing force and resistance force of the "7"-shaped fixing piece on the MOS tube. Such a sharp angle design can provide a larger contact area and stronger pressure, ensuring a close fit between the fixing piece and the MOS tube, and also making the gap at the corner larger, which can effectively improve the stability and reliability of the heat dissipation structure, prevent loosening and falling off, and ensure the normal operation and long-term stability of the electric scooter controller.

[0010] The utility model is further configured as follows: uniformly distributed abutment portions are provided on the abutment side, and a protrusion facing the inside of the "7"-shaped fixing piece is provided at the bottom end of the abutment portion.

[0011] By adopting the above technical solution, when the "7"-shaped fixing piece squeezes the MOS tube through external force, the protrusion facing the inside of the "7"-shaped fixing piece can better play a supporting role. The cross-section of the protrusion is arched and has strong supporting force, which enables the "7"-shaped fixing piece to be used for a long time.

[0012] The utility model is further configured as follows: a mounting groove is provided on the side wall of the shell, so that the circuit board is inserted into the shell through the mounting groove.

[0013] By adopting the above technical solution, the structure for installing the circuit board is simple, and it can be installed by only cutting grooves in the side wall, which is highly practical.

[0014] The utility model is further configured as follows: the installation groove is arranged at one end of the shell, the embedding groove and the installation groove are arranged opposite to each other, and there is a gap between the installation groove and the shell.

[0015] By adopting the above technical solution, the gap between the mounting groove and the shell allows the components to dissipate heat better when the circuit board is working, which can effectively improve the heat dissipation performance of the electric scooter controller.

[0016] The utility model is further configured as follows: a plurality of evenly distributed long grooves are provided on both sides of the shell and the shell is made of aluminum alloy.

[0017] By adopting the above technical solution, the long groove set in the controller housing makes the controller lightweight, which is convenient for engaging with other components. The aluminum alloy material has the characteristics of high strength, light weight, strong plasticity and low cost, so that it plays a better role in the use of the electric scooter controller.

[0026] A heat dissipation structure for an electric scooter controller, including a controller. The controller includes a circuit board 1, a MOS tube 2 disposed on one side of the circuit board 1, and a housing 3 sleeved outside the circuit board 1. An embedding groove 4 and a "7"-shaped fixing member 5 disposed in the embedding groove 4 are provided inside the housing 3. After the circuit board 1 is installed in the housing 3, one side of the "7"-shaped fixing member 5 is pressed into the embedding groove 4 by an external force, so that the other side of the "7"-shaped fixing member 5 forms an extrusion on the MOS tube 2, thereby abutting the "7"-shaped fixing member 5 against the MOS tube 2, and fixing the circuit board 1 in the housing 3. After the circuit board 1 is installed in the housing 3, under the pressure of an external force, the "7"-shaped fixing member 5 is extruded onto the MOS tube 2 to form a certain pressure, which can effectively reduce the shaking and loosening phenomena of the circuit board 1 during movement or vibration. This fixing method can ensure the stability and reliability of the controller and reduce the risk of failure caused by external impact or vibration.

[0027] Preferably, the "7"-shaped fixing member 5 includes a abutting side 6 and an inserting side 7. A abutting step 8 is provided on the inner wall of one side of the embedding groove 4. After the "7"-shaped fixing member 5 is pressed into the embedding groove 4, the corner of the "7"-shaped fixing member 5 abuts against the abutting step 8, so that the "7"-shaped fixing member 5 fixes the circuit board 1, making the installation and disassembly of the circuit board 1 more convenient and fast. When maintenance or replacement of the circuit board 1 is required, the fixing member only needs to be removed, and the circuit board 1 can be easily taken out or installed, improving the efficiency of disassembly, assembly and maintenance.

[0028] Preferably, the corner of the "7"-shaped fixing member 5 is an acute angle, and the acute angle is approximately between, and the angle between about 70° and 90° is to increase the extrusion force and abutting force of the "7"-shaped fixing member 5 on the MOS tube 2. Such an acute angle design can provide a larger contact area and stronger pressure, ensure the close fit between the fixing member and the MOS tube 2, and also make the gap at the corner larger, which can effectively improve the stability and reliability of the heat dissipation structure, prevent loosening and falling off, and ensure the normal operation and long-term stability of the electric scooter controller.

[0029] Preferably, uniformly distributed abutting portions 9 are provided on the abutting side 6, and a protrusion 10 facing the inside of the "7"-shaped fixing member 5 is provided at the bottom end of the abutting portion 9. When the "7"-shaped fixing member 5 extrudes the MOS tube 2 by an external force, the protrusion 10 facing the inside of the "7"-shaped fixing member 5 can better play a supporting role. The cross section of the protrusion 10 is arched and has strong supporting force, enabling the long-term use of the "7"-shaped fixing member 5.

[0030] Preferably, an installation groove 11 is provided on the side wall of the housing 3, so that the circuit board 1 is inserted into the housing 3 through the installation groove 11, making the structure for installing the circuit board 1 simple. Only by opening a slot on the side wall can it be installed, and it has strong practicability.

[0031] Preferably, the installation groove 11 is provided at one end inside the housing 3, and the embedding groove 4 is arranged opposite to the installation groove 11. There is a gap between the installation groove 11 and the inside of the housing 3. The gap between the installation groove 11 and the inside of the housing 3 enables better heat dissipation of each component when the circuit board 1 is working, and can effectively improve the heat dissipation performance of the electric scooter controller.

[0032] Preferably, a plurality of uniformly distributed long grooves 12 are provided on both sides of the housing 3, and the housing 3 is made of aluminum alloy.
