The structure of the electronic control assembly 100 according to an embodiment of the present invention is described below with reference to the drawings.

According to the utility model discloses automatically controlled subassembly 100, as shown in fig. 1 and fig. 2, include: an electronic control box 1, a fixing plate 2, a circuit board 3 and a temperature sensor (not shown). An accommodating cavity 10 is defined in the electric control box 1, and a through hole 13 is formed in the electric control box 1. The fixing plate 2 is arranged in the accommodating cavity 10 and connected with the electronic control box 1, as shown in fig. 3 and 4, a supporting rib 23 is arranged on the fixing plate 2, and a matching position is arranged on the supporting rib 23 corresponding to the through hole 13. The circuit board 3 is established on fixed plate 2, thereby circuit board 3 is through fixing on fixed plate 2 and firmly set up in automatically controlled box 1, and the setting of fixed plate 2 is used for supporting circuit board 2, avoids circuit board 2 impaired in automatically controlled box 1.

The temperature sensor is arranged on the matching position of the supporting rib 23, the temperature sensor is connected with the circuit board 2 through an electric wire, and at least part of the temperature sensor extends out of the electric control box 1 through the through hole 13.

It can be understood that in the embodiment of the present invention, the temperature sensor is disposed on the matching position of the supporting rib 23 of the fixing plate 2, and the temperature sensor does not need to be fixed by an independent fixing bracket and a plurality of screws as in the prior art, thereby avoiding the problem of excessive number of parts caused by the additional setting of the fixing bracket. Moreover, in order to better protect the circuit board 3, the fixing plate 2 itself usually needs more protruding strips, and the supporting rib 23 is formed by one of the protruding strips to support the temperature sensor, so that the structural complexity of the fixing plate 2 is not increased, but the fixing bracket can be saved.

And temperature sensor sets up on brace rod 23, and temperature sensor can not only obtain the support of brace rod 23, still can obtain the support of automatically controlled box 1 because of passing perforation 13, and under the dual bracing effect, temperature sensor's installation is more firm. Particularly, when the temperature sensor is arranged at a position with large wind power, the phenomenon that the temperature sensor is easy to fall off in work can be avoided.

According to the electric control assembly 100 of the embodiment of the present invention, the supporting ribs 23 are disposed on the fixing plate 2 for fixing the circuit board 3, so that the problem of excessive number of parts caused by additional fixing brackets can be avoided; the temperature sensor is more stable to install and not easy to fall off under the double-support effect of the support rib 23 and the electric control box 1.

In some embodiments, as shown in fig. 3 and 4, the end of the support rib 23 is provided with a fitting groove 24, and the temperature sensor is located in the fitting groove 24. The temperature sensor is limited by the matching groove 24, the assembling process is simple, the contact area is large, and the installation is stable.

Specifically, the fitting groove 24 is opened at a side away from the circuit board 3, and as shown in fig. 4 and 5, opposite walls of the fitting groove 24 are provided with catching projections 241 for catching the temperature sensor. The fitting groove 24 is opened at one side, the temperature sensor is very easily inserted into the fitting groove 24, and the click protrusion 241 is provided to prevent the temperature sensor from being released from the opened side of the fitting groove 24.

More specifically, as shown in fig. 4 and 3, the support rib 23 is integrally formed with an extension plate 25 at an end portion thereof, the extension plate 25 is disposed along at least a partial contour of the fitting groove 24, and the extension plate 25 extends into the through hole 13 to support the temperature sensor together with the electronic control box 1. Therefore, the matching groove 24 is lengthened, the contact area between the inner wall of the matching groove 24 and the temperature sensor is increased, and the installation stability of the temperature sensor is further improved. The extending plate 25 extends into the through hole 13, the temperature sensor is supported by the electronic control box 1 through the extending plate 25, and therefore when the supporting ribs 23 shake relative to the electronic control box 1, the electronic control box 1 generates friction force for loosening the temperature sensor.

Alternatively, as shown in fig. 5, the mating groove 24 has a U-shaped profile, and the mating groove 24 is provided with catching protrusions 241 at the ends of the opposite side walls. Further optionally, the extension plate 25 is a semicircular plate.

Advantageously, as shown in fig. 5 and 4, a rib 242 is further provided in the fitting groove 24, not only increasing the structural strength inside the fitting groove 24, but also supporting the temperature sensor to ensure that the temperature sensor can contact with the rib 242. Here, the contour dimension of the fitting groove 24 is larger than the contour dimension of the temperature sensor, and when the temperature sensor surface has a bump, the contact area between the temperature sensor and the inner wall of the fitting groove 24 is rather small. The convex rib 242 can be arranged to avoid the convex point on the surface of the temperature sensor as much as possible and contact with the temperature sensor.

Of course, in the embodiment of the present invention, the structure of the engaging position is not limited to the engaging groove 24. For example, the support rib 23 may be provided with a plug, and the temperature sensor may be provided with a plug hole inserted into the plug, where the plug forms the mating position. For another example, a glue layer is disposed on the support rib 23, and the temperature sensor is adhered to the glue layer, so that a matching position is formed at the glue layer.

In some embodiments, as shown in fig. 2 and 4, the fixing plate 2 includes a frame 22 disposed outside the edge of the circuit board 3. The frame 22 can limit the circuit board 3 and keep the circuit board 3.

Specifically, as shown in fig. 6 and 4, the fixing plate 2 is provided with a frame 22 outside at least both side edges of the circuit board 3.

More specifically, the frame 22 on the side of the edge of the circuit board 3 closest to the inner wall of the electronic control box 1 is higher than the frame 22 on the other side of the circuit board 3. For example, in fig. 2, the vertical direction is the height direction, and the front edge of the circuit board 3 is closest to the inner wall of the electronic control box 1, so that the frame 22 on the front side of the fixing plate 2 is higher than the frame 22 on the rear side of the fixing plate 2, the frame 22 on the left side, and the frame 22 on the right side.

It can be understood that, when a certain edge of the circuit board is too close to the inner wall of the electrical control box, the component at the edge is likely to touch the inner wall of the electrical control box. In practical use, the electric control box is difficult to avoid generating large vibration due to over wind and the like, and components and parts are difficult to avoid contacting with the electric control box with large vibration and can be damaged. Therefore, in order to avoid damage to components in the prior art, the four side edges of the circuit board are usually arranged far away from the inner wall of the electronic control box. The frame 22 closest to the inner wall of the electric control box 1 is arranged higher, and the frame 22 is used for separating the components from the inner wall of the electric control box, so that the damage of the components is avoided, the distance between the edge of the circuit board and the inner wall of the electric control box is reduced, and the size of the electric control assembly 100 is reduced.

The wiring fixing hooks 27 are additionally arranged on the periphery of the four sides of the fixing plate 2, so that the wiring in the electric control box 1 can be limited and fixed, the disorder of the internal wiring is avoided, and the potential safety hazard caused by the disorder of the wiring in the electric control box is avoided.

Specifically, as shown in fig. 6, the periphery of the fixing plate 2 is spaced apart from the inner wall of the electrical control box 1, and the routing fixing hooks 27 are formed to be bent into a hook shape toward the inner wall of the electrical control box 1 after gradually approaching toward the inner wall of the electrical control box 1 in the direction away from the circuit board 3.
