[0053] The following describes the driver of an embodiment of this application. However, it will be readily apparent that the embodiments of this application provide many suitable inventive concepts that can be implemented in a wide range of specific contexts. The specific embodiments disclosed are merely illustrative of the use of this application in a particular manner and are not intended to limit the scope of this application.
[0054] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It is understood that these terms, such as those defined in commonly used dictionaries, shall be interpreted as having a meaning consistent with the relevant art and the background or context of this application, and shall not be interpreted in an idealized or overly formal manner, unless specifically defined herein.
[0055] Figure 1 This is a schematic diagram illustrating a driver R according to an embodiment of this application. For example, the aforementioned driver R may be disposed in a vehicle and electrically connected to a motor in the vehicle to control the motor to output stable torque and speed. The aforementioned vehicle may be, for example, a car, truck, bus, forklift, or tractor, but is not limited thereto.
[0056] Figure 2 It means Figure 1 A cross-sectional view along the AA direction. (See example...) Figure 1 and Figure 2 As shown, in this embodiment, the aforementioned driver R mainly includes an outer cover 100, a base plate 200, an insulating plate 300, a circuit board 400, multiple electrode heads 500, and multiple O-rings 700.
[0057] The outer cover 100 and the base plate 200 can be joined together to form an internal space S, in which the insulating plate 300, circuit board 400, and electrode head 500 can be housed. In this specification, "joint" refers to fixing two or more components together by adding external components or processing. The outer cover 100 has multiple holes 110 communicating with the internal space S and the external environment. The electrode head 500 can pass through these holes 110 to be exposed in the external environment, allowing the user to connect the electrode head 500 to the motor using external wiring. It should be noted that, except for the aforementioned holes 110, the internal space S is completely sealed (i.e., there are no gaps at the connection between the outer cover 100 and the base plate 200), thus preventing liquids or foreign objects from entering the internal space S and causing damage to the components within it.
[0058] The base plate 200 may include materials that facilitate heat dissipation, such as metal or graphite, but is not limited thereto. The insulating plate 300 is fixed to the base plate 200 and may include electrically insulating materials. For example, the insulating plate 300 may be fixed to the base plate 200 by locking components (e.g., screws or rivets) or by adhesive. In this embodiment, a recess 211 may be formed in the opposite direction on the surface 210 of the base plate 200 facing the outer cover 100, and the insulating plate 300 may be accommodated in this recess 211. This reduces the overall thickness of the driver R, achieving miniaturization of the driver R, while simultaneously positioning the insulating plate 300, increasing the contact area with the base plate 200, and improving heat dissipation efficiency.
[0059] Please see Figure 3A and Figure 3B The upper surface 301 of the insulating plate 300 may include a grid structure 310 formed by multiple ribs, thereby enhancing its structural strength. Furthermore, the upper surface 301 of the insulating plate 300 may also include multiple positioning posts 320 and multiple screw holes 340, wherein the positioning posts 320 protrude from the upper surface 301 of the insulating plate 300, and the screw holes 340 are arranged in two rows aligned with each other. The upper surface 301, for example, faces the outer cover 100.
[0060] On the lower surface 302 of the insulating plate 300, opposite to the aforementioned upper surface 301, at least one first positioning portion 350 may be formed, and the base plate 200 may have at least one second positioning portion 220 corresponding to the first positioning portion 350. For example... Figure 2 As shown, when the insulating plate 300 is disposed on the base plate 200, the first positioning portion 350 and the second positioning portion 220 can be connected to each other, thereby positioning the insulating plate 300 relative to the base plate 200. In this embodiment, the first positioning portion 350 may be a protrusion extending toward the base plate 200, and the second positioning portion 220 may be a recess, but is not limited thereto. In some embodiments, the first positioning portion 350 may be a recess, and the second positioning portion 220 may be a protrusion extending toward the insulating plate 300.
[0061] Please continue reading. Figure 2 The circuit board 400 can be placed on the insulating plate 300 and can be separated from the base plate 200 by a distance to avoid short circuit between the circuit board 400 and the base plate 200.
[0062] The electrode head 500 can be disposed on the circuit board 400 and electrically connected to the circuit on the circuit board 400. A positioning groove 530 can be formed on the electrode head 500, which corresponds to the positioning post 320 on the insulating plate 300. When the electrode head 500 is disposed on the circuit board 400, the positioning post 320 can pass through the circuit board 400 and enter the positioning groove 530 to position the aforementioned electrode head 500.
[0063] The driver R may include different types of electrode heads 500, and the positioning posts 320 corresponding to different electrode heads 500 may be located at different positions. For example, in this embodiment, each electrode head 500 may correspond to two positioning posts 320 to achieve at least one axial limit, and the types of electrode heads 501 and 502 in the electrode heads 500 are different. The line L1 connecting the two positioning posts 321 corresponding to the electrode head 501 may not be parallel to the line L2 connecting the two positioning posts 322 corresponding to the electrode head 502 (e.g., ...). Figure 3A The two dashed lines shown are for user installation and verification, achieving a foolproof structural design.
[0064] Figure 4 This is a schematic diagram showing the actuator R after omitting the outer cover 100 and the O-ring 700, and Figure 5 It means Figure 1 A cross-sectional view along the BB direction. (e.g.) Figures 2 to 5 As shown, each electrode head 500 may include a connecting portion 510 and a plurality of fixing portions 520, wherein the connecting portion 510 may be exposed through the hole 110 on the outer cover 100, and the connecting portion 510 may be disposed among the plurality of fixing portions 520.
[0065] The driver R may include multiple screws 600, which, after passing through the fixing portion 520 of the electrode head 500 and the circuit board 400, engage with screw holes 340 on the insulating plate 300, thereby securing the electrode head 500 to the insulating plate 300. Since the electrode head 500 is secured to the insulating plate 300 via the fixing portion 520 on the opposite side of the connection portion 510, when the user applies torque to secure the external cable to the connection portion 510, the torque can be transmitted to the insulating plate 300 and withstand sufficient resistance and strength. Therefore, the electrode head 500 will not detach due to the aforementioned torque, and the circuit board 400, the electrode head 500, or other components in the driver R will not crack or be damaged due to the aforementioned torque.
[0066] In addition, such as Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the connecting portion 510 of the electrode head 500 can be divided into a first segment 511 and a second segment 512. The second segment 512 is located between the first segment 511 and the circuit board 400, and the end of the first segment 511 not connected to the second segment 512 can be used to connect external wires. The size of the second segment 512 can be larger than the size of the first segment 511. In some embodiments, the size refers to the diameter or width of the electrode head 500. Therefore, when viewed along the normal direction of the circuit board 400, the projection of the first segment 511 on the circuit board 400 will be surrounded by the projection of the second segment 512 on the circuit board 400.
[0067] For example, in this embodiment, the first segment 511 may have a circular cross-section and a tapered structure. That is, the diameter at the junction of the first segment 511 and the second segment 512 will be larger than the diameter of the end of the first segment 511 that is not connected to the second segment 512. In some embodiments, the second segment 512 may have a square cross-section and a cubic structure. It should be noted that the user may also change the shape of the connecting portion 510 according to requirements, and it is not limited to this.
[0068] Please see Figure 2 , Figure 5 ,as well as Figure 6 The O-ring 700 may have an inner surface 710 and an outer surface 720, and may be fitted onto the first segment 511 of the connecting portion 510 of the electrode head 500. The inner surface 710 of the O-ring 700 may contact the connecting portion 510, and the outer surface 720 of the O-ring 700 may contact the inner wall surface of the hole 110 of the outer cover 100. Therefore, the O-ring 700 can seal the communication path between the internal space S and the external environment, thereby ensuring the waterproof and sealing effect within the internal space S.
[0069] The inner surface 710 and outer surface 720 of the O-ring 700 can be formed with a wavy structure, and the connecting part 510 and the inner wall surface of the hole 110 where the two meet can also be formed with a corresponding wavy structure. In this way, the O-ring 700 increases the water seepage distance, achieving the effect of not being easily seeped by water and not easily falling off, which can further improve the waterproof effect.
[0070] In addition, since the size of the second section 512 on the connecting part 510 can be larger than the size of the first section 511, it can be ensured that the O-ring 700 remains in contact with the inner wall surface of the hole 110 and does not slide down.
[0071] When installing the O-ring 700, it can first be inserted into the hole 110 of the outer cover 100. Then, when the outer cover 100 and the base plate 200 are combined, the O-ring 700 can be fitted into the first section 511 of the connecting part 510 of the electrode head 500, thereby achieving a tight fit with the connecting part 510. Through the aforementioned steps, the installation of the O-ring 700 can be completed.
[0072] In summary, this application provides a driver including an insulating plate, a circuit board, an electrode head, a plurality of screws, an outer cover, and an O-ring. The circuit board is disposed on the insulating plate. The electrode head is disposed on the circuit board and includes a connecting portion and a plurality of fixing portions, wherein the connecting portion is disposed between the aforementioned fixing portions. The screws pass through the fixing portions and engage with the insulating plate. The O-ring connects to the outer cover and is tightly fitted with the connecting portion.
