Description

Technical Field

[0001] This utility model belongs to the field of transportation tools technology, and relates to a scooter controller. Background Technology

[0002] Traditional scooter controllers typically consist of a heatsink base, a mainboard, and a top cover. The mainboard integrates numerous electronic components, including connectors (MOSFETs). MOSFETs perform critical tasks such as power conversion during operation, generating significant heat. In traditional designs, to ensure MOSFET heat dissipation, a separate clamp and multiple screws (usually 3-6) are used to secure the MOSFETs to the heatsink. During assembly, the mainboard is first mounted on the heatsink base, then secured with screws, and finally the top cover is placed on top and tightened again with screws.

[0003] Problems: First, the traditional mounting method for MOSFETs results in low assembly efficiency, a cumbersome assembly process, and a significant time consumption. Second, the use of multiple screws and individual clamping blocks increases component costs, while the large manpower required during assembly leads to an overall increase in costs. Third, improper operation or uneven force during the screw tightening of MOSFETs can easily damage components such as MOSFETs, affecting product quality and yield. Summary of the Invention

[0004] This invention addresses the aforementioned problems by providing a scooter controller that solves the issues of low efficiency, high cost, and easy damage to components in the assembly process of traditional scooter controllers. It enables fast and efficient assembly, reduces production costs, improves product quality and stability, and ensures that the controller can stably control the brushless motor during scooter operation, thereby enhancing the overall performance of the scooter and the user experience.

[0005] According to the technical solution of this utility model: a scooter controller includes a heat dissipation bottom shell, a controller motherboard, and a top cover. The controller motherboard is installed on the heat dissipation bottom shell, and the top cover is connected to the heat dissipation bottom shell, sealing the controller motherboard in the cavity formed by the top cover and the heat dissipation bottom shell. The controller motherboard is installed in a controller motherboard slot on the inner wall of the heat dissipation bottom shell, and the top cover is fastened to the heat dissipation bottom shell.

[0006] The controller motherboard has a MOSFET on one side along the width direction and a plug-in terminal on the other side along the width direction. The MOSFET is in close contact with the heat dissipation block of the heat dissipation base.

[0007] The bottom surface of the top cover has an integrally connected clamping wedge, and the lower end of the clamping wedge clamps the MOSFET.

[0008] As a further improvement of this utility model, top cover hooks are respectively provided on both sides of the width direction of the top cover, and top cover fixing seats are respectively provided on both sides of the width direction of the heat dissipation bottom shell. The top cover hooks and the top cover fixing seats are fastened together.

[0009] As a further improvement of this utility model, the two ends of the upper cover are respectively provided with integrally connected end plates, and the screws pass through the end plates and are connected to the upper cover fixing holes of the heat dissipation bottom shell.

[0010] As a further improvement of this utility model, the end plates at both ends of the upper cover along its length are respectively provided with connecting lugs.

[0011] As a further improvement of this utility model, the bottom surface of the heat dissipation base is provided with heat dissipation ribs.

[0012] As a further improvement of this utility model, the clamping inclined block has several blocks, and the several clamping inclined blocks are evenly distributed along the length direction of the upper cover.

[0013] As a further improvement of this utility model, the bottom surface of the upper cover is also provided with a bottom plate pressing part, which is used to press the controller motherboard.

[0014] The technical advantages of this utility model are as follows: 1. Efficient and convenient assembly: This utility model sets a controller motherboard slot in the heat dissipation base shell, which allows the controller motherboard to be installed quickly without the need for screw fixation; at the same time, by using the clamping wedge of the upper cover, the plug-in terminal (MOS transistor) is locked and attached to the heat dissipation block of the heat dissipation base shell when the upper cover is fixed. Compared with the traditional method of fixing the MOS transistor with clamping blocks and multiple screws, this greatly improves the assembly efficiency and saves the assembly time.

[0015] 2. Cost reduction: The use of individual pressure blocks and multiple screws and other parts is reduced, thus lowering raw material costs; improved assembly efficiency reduces labor input, further reducing production costs.

[0016] 3. Improved product quality: It avoids component damage caused by improper operation during the assembly and locking of MOSFETs, improves the product yield and quality stability, and enables the scooter controller to control the brushless motor more reliably during operation, ensuring the stable operation of the scooter.

[0017] 4. Stable and reasonable structure: The top cover is fixed by hooks and quick-fixing brackets on the heat dissipation base. This connection method makes the entire controller structure more stable and can better resist the influence of external forces such as vibration during the operation of the scooter, ensuring the normal operation of the internal electronic components.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] Figure 1-5 The components include a heat dissipation base 1, a heat dissipation block 1.11, a top cover mounting base 1.12, a controller motherboard slot 1.13, a top cover mounting hole 1.14, a controller motherboard 2, a MOSFET 2.11, a connector terminal 2.12, a top cover 3, a clamping wedge 3.11, a top cover hook 3.12, a motherboard clamping part 3.13, and screws 4.

[0026] like Figure 1-5 As shown, this utility model is a scooter controller, including a heat dissipation base shell 1, a controller motherboard 2, and a top cover 3. The controller motherboard 2 is installed on the heat dissipation base shell 1, and the top cover 3 is connected to the heat dissipation base shell 1, sealing the controller motherboard 2 in the cavity formed by the top cover 3 and the heat dissipation base shell 1. The controller motherboard 2 is installed in the controller motherboard slot 1.13 on the inner wall of the heat dissipation base shell 1. The top cover 3 is snapped into the heat dissipation base shell 1, which facilitates the quick installation of the controller motherboard 2.

[0027] The controller motherboard 2 has a MOSFET 2.11 on one side along its width and a connector terminal 2.12 on the other side. The MOSFET 2.11 is in close contact with the heat dissipation block 1.11 of the heat sink 1. The heat dissipation block 1.11 is used to dissipate heat from the MOSFET 2.11. The number of MOSFETs 2.11 can be set as needed, such as 6 or 12. Because the MOSFETs 2.11 generate a lot of heat during operation, and the controller will stop working or be damaged when they reach a certain temperature, the MOSFETs 2.11 need to be in close contact with the heat dissipation block 1.11.

[0028] The bottom surface of the upper cover 3 has an integrally connected clamping wedge 3.11, the lower end of which clamps the MOSFET 2.11. In actual production, there are several clamping wedges 3.11, and these wedges are evenly distributed along the length of the upper cover 3. Each clamping wedge 3.11 has a chamfer, and the spacing between adjacent clamping wedges 3.11 is equal.

[0029] The upper cover 3 is provided with upper cover hooks 3.12 on both sides of the width direction, and the heat dissipation bottom shell 1 is provided with upper cover fixing seats 1.12 on both sides of the width direction. The upper cover hooks 3.12 and the upper cover fixing seats 1.12 are fastened together.

[0030] Furthermore, in order to further enhance the reliable connection between the top cover 3 and the heat dissipation base 1, the two ends of the top cover 3 are respectively provided with integrally connected end plates, and the screw 4 passes through the end plate and is connected to the top cover fixing hole 1.14 of the heat dissipation base 1.

[0031] like Figure 5 As shown, the end plates at both ends of the upper cover 3 along its length are respectively provided with connecting lugs. In practice, one end plate has two screw holes, and the other end plate has one screw hole in the middle; a connecting lug is provided between the two screw holes, and a connecting lug is provided on the outside of the screw hole in the middle of the other end plate.

[0032] The bottom surface of the upper cover 3 is also provided with a base plate clamping part 3.13, which is used to clamp the controller motherboard 2. The base plate clamping part 3.13 is constructed as a narrow strip-shaped closed ring, and the inner ring of the base plate clamping part 3.13 is hollow, so as to both clamp the controller motherboard 2 and facilitate the heat dissipation of the controller motherboard 2. In this application, there are three base plate clamping parts 3.13, which are disposed on the vertically extending plate on the bottom surface of the upper cover 3.

[0033] The bottom surface of the heat dissipation base 1 is provided with heat dissipation fins to effectively improve the heat dissipation effect of the heat dissipation base 1.

[0034] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
