Description

Technical Field

[0001] The utility model relates to the technical field of electric tricycle controllers, in particular to an electric vehicle controller with good heat dissipation effect. Background Art

[0002] The electric vehicle controller is a core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the electric vehicle. It is one of the important components of the electric vehicle. The electric vehicle controller is equipped with a power tube, namely a MOS tube. When the controller is working, the MOS tube will generate a lot of heat. If the heat cannot be effectively released to the outside of the controller, it will damage the mainboard inside the controller and the electronic components installed on the mainboard, causing the controller to fail and shorten the service life of the controller.

[0003] The electric vehicle controllers currently sold and used on the market usually achieve the purpose of heat dissipation by setting fins on the outer surface of the shell. Since the MOS tube generates a lot of heat during operation, it is not possible to release the heat to the surrounding environment in a timely and effective manner by only setting fins on the shell surface. In addition, since the MOS tube is generally fixed to the controller motherboard with screws, the heat generated by the MOS tube cannot be transferred to the controller shell in a timely manner, resulting in heat accumulation inside the controller. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides an electric vehicle controller with good heat dissipation effect.

[0005] The technical solution of the utility model is:

[0007] Furthermore, the heat dissipation structure includes heat dissipation ribs, and the heat dissipation ribs are vertically fixedly arranged on the upper surface of the wing plate and / or the lower surface of the base plate.

[0008] Furthermore, the heat dissipation ribs are provided in plurality, and heat dissipation channels are formed between adjacent heat dissipation ribs.

[0009] Furthermore, the outer surface of the heat dissipation ribs is evenly distributed with heat dissipation concave and convex points.

[0010] Furthermore, the heat dissipation structure also includes a heat dissipation groove, which is arranged at an axial position on the upper surface of the base plate, and the depth of the heat dissipation groove is set to 2 / 3 of the thickness of the base plate.

[0011] Furthermore, the controller also includes a MOS tube mounting platform; the MOS tube mounting platform is arranged inside the shell, and is fixedly arranged on the upper surface of the base plate, and is arranged adjacent to the heat dissipation groove.

[0012] Furthermore, the controller also includes a controller mainboard; the controller mainboard is arranged in the heat dissipation groove, and has a gap of 5mm-10mm with the inner wall of the heat dissipation groove.

[0013] Furthermore, the inner side wall of the main shell is provided with a rib, the rib forms an angle of 30° with the inner side wall of the main shell, and the rib, the main shell and the bottom plate form a slot; the MOS tube mounting platform is provided with a crimping spring sheet, and the crimping spring sheet is fixedly arranged in the slot for installing and fixing the MOS tube.

[0014] Furthermore, a thermally conductive insulating film is provided between the MOS tube and the base plate.

[0015] Furthermore, the main shell and the bottom plate are integrally formed, and the heat dissipation ribs and the bottom plate are integrally formed.

[0016] The beneficial effects of the utility model are:

[0017] 1. The electric vehicle controller recorded in the utility model uses a crimping spring to fix the MOS tube inside the main shell, and the MOS tube is fitted on the bottom plate, and the controller mainboard is suspended in the heat dissipation groove near the MOS tube. When the controller is working, only a small amount of heat emitted by the MOS tube is transferred to the controller mainboard, and the controller mainboard can effectively dissipate heat through the heat dissipation groove, ensuring that the controller mainboard can operate stably. The MOS tube transfers heat through the bottom plate to the wing plate outside the main shell through the thermal insulation film, which can realize efficient and rapid heat transfer from the bottom plate to the outside of the main shell, avoiding heat accumulation inside the main shell.

[0018] 2. The electric vehicle controller recorded in the utility model can form multiple heat dissipation channels at the wing plate by means of multiple heat dissipation ribs arranged at the wing plate of the bottom plate and the concave-convex points arranged on the outer surface of the heat dissipation ribs.

[0024] The present invention is described in detail below by way of embodiments in conjunction with the accompanying drawings.

[0025] As attached Figure 1 To Attachment Figure 3 As shown, this embodiment describes an electric vehicle controller with good heat dissipation effect, including a base plate and a main shell.

[0026] The bottom plate is set as a cuboid, and a heat dissipation groove is opened at the axis position of the upper surface thereof. The depth of the heat dissipation groove is preferably set to 2 / 3 of the thickness of the bottom plate.

[0027] The main shell is configured as a U-shaped trough body and is located on the upper surface of the bottom plate.

[0028] The width of the main shell is greater than the width of the heat dissipation slot. After being fixedly connected with the bottom plate, the part of the bottom plate located inside the main shell forms a group of relatively arranged MOS tube mounting platforms.

[0029] The portion of the bottom plate located on the outer side of the main shell is configured as a wing plate, and a plurality of heat dissipation ribs are vertically and evenly spaced on the upper surface of the wing plate, forming a heat dissipation channel between adjacent heat dissipation ribs.

[0030] The height of the heat dissipation rib is smaller than the height of the main shell, and the outer surface of the heat dissipation rib is evenly distributed with continuous heat dissipation concave and convex points.

[0031] The controller mainboard is arranged in the heat dissipation groove, with a gap of 5mm-10mm between the inner wall of the heat dissipation groove, and is preferably arranged to be flush with the upper surface of the bottom plate.

[0032] The main shell is provided with a corrugated bar on its inner side wall, the corrugated bar and the inner side wall form an angle of 30 degrees, and the corrugated bar, the main shell and the bottom plate form a slot, and the slot is used for fixing and installing the crimping spring piece.

[0033] The MOS tube is mounted on the MOS tube mounting platform and fixed by crimping springs. A heat-conducting insulating film is arranged between the MOS tube and the base plate.

[0034] When the controller is working, the heat emitted by the MOS tube is transmitted to the base plate, and the base plate transfers the heat to the heat dissipation wing plate, and dissipates the heat through the heat dissipation ribs, the heat dissipation channels formed by the heat dissipation ribs, and the heat dissipation concave and convex points on the surface of the heat dissipation ribs, thereby achieving the purpose of high-efficiency heat dissipation.
