Description

Technical Field

[0001] The utility model relates to the technical field of electric scooter controllers, and particularly relates to an electric scooter controller. Background Art

[0002] A Chinese patent with the publication number CN215682967U discloses a highly protective electric scooter controller, which includes a housing, control elements arranged inside the housing, and connecting wires that are electrically connected to the control elements and extend outside the housing. A protective structure is provided between the connecting wires and the housing. The protective structure includes a protective sleeve body arranged between the housing and the connecting wires, a sealing glue groove arranged inside the protective sleeve body, and a plurality of wire passing holes arranged at the bottom of the sealing glue groove. The sealing glue groove is filled with glue.

[0003] The above-mentioned electric scooter controller solves some defects existing in the prior art, but there are still some deficiencies in actual use. For example, in a scooter controller, a MOS transistor (metal-oxide-semiconductor field-effect transistor), as a key component for controlling the driving current of the motor, is prone to generate a large amount of heat during long-term operation. If the heat cannot be dissipated in a timely and effective manner, the temperature will rise sharply, which will affect the performance stability of the MOS transistor and may even cause failures or damages. This will not only reduce the user experience of the scooter but also pose a threat to the safety of the rider. However, the above-mentioned electric scooter controller installs the circuit board in an overall sealed form. During heat dissipation, the heat generated by the MOS transistor will be dissipated into the air inside the housing, and then the high-temperature gas will exchange heat with the housing. The entire heat dissipation process is inefficient, resulting in poor heat dissipation effect of the electric scooter controller, and the heat dissipation performance needs to be improved.

[0004] Therefore, an electric scooter controller is proposed. Summary of the Utility Model

[0026] The following will describe in detail the implementation manners of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0027] Please refer to Figures 1 to 5 As shown, this embodiment provides an electric scooter controller, which includes a housing 1 installed inside the outer shell of the electric scooter. The bottom of the housing 1 is open. A bottom plate 2 is fixedly installed at the bottom of the housing 1. A circuit board 3 is fixedly installed on the top of the bottom plate 2. A heat dissipation component 5 for dissipating the heat generated by the MOS tube 4 on the circuit board 3 is arranged inside the housing 1;

[0028] Among them, the circuit board 3 can be the main board of the Kugoo Kirin S1 electric scooter controller.

[0029] Among them, the heat dissipation component 5 includes a plurality of first heat exchange fins 501, heat pipes 504 and a mounting plate 503. Slots 502 are provided at the bottoms of the plurality of first heat exchange fins 501. The first heat exchange fins 501 are clamped on the surface of the MOS transistor 4 through the slots 502. In order to ensure that the first heat exchange fins 501 can be in full contact with the surface of the MOS transistor 4, a thermal grease layer is provided between the first heat exchange fins 501 and the MOS transistor 4. The first heat exchange fins 501 are fixedly connected to the evaporation section of the heat pipe 504. An installation hole 101 is provided at the top of the housing 1, and an installation groove 102 communicating with the installation hole 101 is provided at the inner top of the housing 1. The mounting plate 503 is fixedly installed in the installation groove 102 by screws. The condensation section of the heat pipe 504 fixedly penetrates through the mounting plate 503 and extends to the outside of the housing 1.

[0030] By adopting the above technical solution, when the MOS transistor 4 operates, the heat generated by the MOS transistor 4 will be quickly transmitted to the evaporation section of the heat pipe 504 through the first heat exchange fins 501, and then the heat absorbed by the heat pipe 504 will be released to the outside through the condensation section of the heat pipe 504, effectively improving the heat dissipation efficiency of the MOS transistor 4.

[0031] Specifically, in order to further improve the heat dissipation effect of the electric scooter controller, a fan 6 is fixedly installed at the top of the housing 1. The fan 6 is arranged directly above the mounting plate 503. By arranging the fan 6, the condensation section of the heat pipe 504 and the second heat exchange fins 505 can be cooled by air, accelerating the heat dissipation efficiency.

[0032] Specifically, both the evaporation section and the condensation section of the heat pipe 504 are arranged in a serpentine shape. By this arrangement, the contact area between the heat pipe 504 and the first heat exchange fins 501 and the second heat exchange fins 505 can be increased, improving the heat exchange efficiency.

[0033] In this embodiment, in order to facilitate fixing the first heat exchange fins 501 on the circuit board 3, support plates 506 are fixedly connected to both ends of the first heat exchange fins 501. A connecting ear 507 is fixedly connected to the bottom of the support plate 506. The connecting ear 507 is fixed to the circuit board 3 by screws, thereby ensuring that the first heat exchange fins 501 can be stably clamped on the MOS transistor 4 and ensuring stable contact between the first heat exchange fins 501 and the MOS transistor 4.

[0034] Specifically, a stepped groove 104 is provided at the bottom of the housing 1. Mounting ears 105 are fixedly connected to the four corners of the stepped groove 104. The bottom plate 2 is arranged in the stepped groove 104. The bottom plate 2 is fixedly connected to the mounting ears 105 by screws. By this arrangement, it is convenient for disassembly and assembly between the bottom plate 2 and the housing 1.

[0035] Specifically, a clamping sleeve is fixedly connected to one side of the housing 1. A wire-binding nut 103 is threadedly installed on the clamping sleeve. The wires on the circuit board 3 can pass through the clamping sleeve, and then by tightening the wire-binding nut 103, the wires in the clamping sleeve are locked, thereby reducing the gap between the wires and the clamping sleeve and effectively reducing the probability of external dust and water stains entering the interior of the housing 1.

[0036] To ensure the sealing performance at the connection between the housing 1 and the bottom plate 2 and at the connection between the mounting plate 503 and the mounting groove 102, a first sealing ring is provided between the housing 1 and the bottom plate 2, and a second sealing ring is provided between the mounting plate 503 and the mounting groove 102.

[0037] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0038] Working principle: When the circuit board 3 is operating, the heat generated by the MOS transistor 4 is quickly transferred to the evaporation section of the heat pipe 504 through the first heat exchange fin 501. Then, the heat absorbed by the heat pipe 504 is released to the outside through the condensation section of the heat pipe 504. At the same time, the fan 6 is started to perform air-cooling on the condensation section of the heat pipe 504 and the second heat exchange fin 505, so as to ensure that the heat generated during the operation of the MOS transistor 4 can be quickly dissipated to the outside, providing guarantee for the continuous and stable operation of the circuit board 3.

[0039] During assembly, the circuit board 3 is fixed on the bottom plate 2, then a thermal grease layer is applied on the MOS transistor 4, and then the first heat exchange fin 501 is clamped on the surface of the MOS transistor 4 through the card slot 502. Then, the first heat exchange fin 501 is fixed on the circuit board 3 by screws in cooperation with the connecting ear 507. Then, the housing 1 is covered on the bottom plate 2. At this time, the mounting plate 503 fits into the mounting groove 102, and the second heat exchange fin 505 extends from the mounting hole 101 to the outside of the housing 1. Then, the mounting plate 503 is fixed in the mounting groove 102 by screws (it should be noted here that threaded holes are provided on the mounting plate 503, and jacks corresponding to the threaded holes on the mounting plate 503 are provided on the top of the housing 1. The lower end of the screw passes through the jack and is threadedly fixed in the threaded hole of the mounting plate 503), and then the fan 6 is fixed on the top of the housing 1 by screws.
