Description

Technical Field

[0001] This utility model relates to the field of electronic control boards, specifically an electronic control board for fans. Background Technology

[0002] The fan electronic control board is the core component for regulating the fan's operating status. It typically consists of a base plate, electronic components soldered onto it (such as microcontrollers, capacitors, resistors, and relays), and wires. Through circuit logic, it controls functions such as motor speed regulation, mode switching (natural wind / sleep wind), timing, and overload protection. Its stability directly affects the fan's performance and lifespan.

[0003] Existing electronic control boards have the following drawbacks during installation: Currently, electronic control boards are typically installed using screws. Screw installation requires specialized tools such as screwdrivers, which are difficult to operate in the confined space inside fans (especially ceiling fans or recessed fans). Tools can easily slip and damage surrounding components. Precise alignment of the substrate screw holes with the fan bracket holes is required during installation; misalignment can lead to substrate warping or screws being tilted and locked in place. Over time, this can cause solder joint cracking, making the electronic control board inconvenient to install and remove. Repairing or upgrading the control board requires removing each screw individually, which is time-consuming and labor-intensive, and screws are easily lost (especially miniature screws), increasing downtime. Therefore, using screws for installation makes the electronic control board inconvenient to install and remove. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides an electronic control board for a fan, which can effectively solve the technical problem that the existing electronic control boards are installed with screws, making it inconvenient to install and disassemble the electronic control board.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: an electronic control board for a fan, including a substrate, several electronic components soldered on the substrate, and several wires. Adjacent electronic components are electrically connected through wires. Several fixing rods are fixedly arranged at the bottom of the substrate, and adjacent fixing rods are symmetrically arranged. One end of the fixing rod extends outward to form a ring portion. The diameter of the fixing rod gradually decreases at the end away from the ring portion. Several connecting blocks are arranged at the end of the fixing rod near the ring portion, and adjacent connecting blocks are symmetrically arranged. Several locking strips are arranged at the end of the fixing rod near the ring portion, and the locking strips extend along the axial direction of the fixing rod, and adjacent locking strips are symmetrically arranged.

[0006] Furthermore, the length of the locking strip is less than the length of the fixing rod, and the locking strip is rectangular in shape.

[0007] Furthermore, a limiting groove is provided at one end of the substrate, and the limiting groove extends along the height direction of the substrate.

[0008] Furthermore, three fixing rods are provided.

[0009] Furthermore, all of the aforementioned fixing rods are on the same horizontal plane.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model is used for the electronic control board of a fan. By setting a fixing rod and connecting blocks and clips on the fixing rod, the electronic control board can be quickly installed and disassembled.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The following is combined Figures 1-3 The present invention provides a detailed description of the electronic control board for a fan:

[0018] An electronic control board for a fan includes a substrate 1, several electronic components 2 soldered onto the substrate 1, and several wires 3. Adjacent electronic components 2 are electrically connected through wires 3. Several fixing rods 5 are fixedly disposed at the bottom of the substrate 1, and adjacent fixing rods 5 are symmetrically arranged. One end of each fixing rod 5 extends outward to form a ring portion 6. The diameter of the fixing rod 5 gradually decreases at the end away from the ring portion 6. Several connecting blocks 8 are disposed at the end of each fixing rod 5 near the ring portion 6, and adjacent connecting blocks 8 are symmetrically arranged. Several locking strips 7 are disposed at the end of each fixing rod 5 near the ring portion 6. The locking strips 7 extend along the axial direction of the fixing rod 5, and adjacent locking strips 7 are symmetrically arranged. The length of each locking strip 7 is less than the length of the fixing rod 5, and the locking strip 7 is rectangular. A limiting groove 4 is disposed at one end of the substrate 1, and the limiting groove 4 extends along the height direction of the substrate 1. Three fixing rods 5 are disposed, and the fixing rods 5 are all on the same horizontal plane.

[0019] By setting a limiting groove 4 on the substrate 1 to form a limiting structure, and in conjunction with the connection of the fixing rod 5, the displacement of the electronic control board caused by vibration or impact can be effectively prevented. The diameter of one end of the fixing rod 5 gradually decreases, which can make the fixing rod 5 form a guide structure, making it easy to accurately insert into the corresponding mounting hole. At the same time, the friction self-locking principle is used to enhance the axial fixing strength, making the installation more stable and firm. The connecting block 8 and the locking strip 7 can achieve rapid pre-positioning, reducing the hole-aligning operation time required by traditional screw fixing. The locking strip 7 can also play a guiding role, further facilitating the alignment of the fixing rod 5 on the electronic control board with the corresponding mounting hole.

[0020] In practical use, the fixing rod 5 at the bottom of the electronic control board is aligned with the corresponding mounting hole. By pressing directly, the locking strip 7 and connecting block 8 on the fixing rod 5 are engaged in the corresponding position, so that the locking strip 7 and connecting block 8 can be quickly snapped together. At the same time, the limiting groove 4 on the base plate 1 is also engaged in the corresponding position to achieve a limiting function and prevent the electronic control board from shifting.

[0021] In this embodiment, the electronic components 2 on the electronic control board are all conventional existing technologies, and the circuit structure and circuit principle of the electronic control board are also conventional existing technologies, which will not be described in detail here.

[0022] The electronic control board for the fan in this embodiment enables quick installation and removal of the electronic control board by setting a fixing rod 5, and connecting blocks 8 and clips 7 on the fixing rod 5. Compared with the traditional installation using screws, the structure is simple and facilitates quick installation of the electronic control board without the need for other tools.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
