In addition, similar numbers in the drawings are used to represent similar components, among which:

[0021] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings. First of all, it should be noted that the directional terms such as up, down, left, right, front, back, inside, outside, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0022] In this application, the terms "install", "set", "arrange", "have", "connect", "connected", and "joined" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] The wall-mounted installation structure for the controller known to those skilled in the art usually adopts the following two forms: first, a plastic back panel is used for snap-on installation. First, the plastic back panel is placed on the installation wall, and then the control box body is snapped together with the back panel; second, a split structure is used for installation. First, the back box body of the controller is installed on the wall as a back panel, and then the front control panel is snapped together with the back box body. These two installation forms have the following defects: Since plastic parts are easy to deform, locking the back panel into the wall will cause structural deformation, resulting in the inability of the snap to normally lock the product. In addition, the above-mentioned installation structure has extremely high requirements for the fit of the installation, and it needs to be pried open with tools when disassembling, which greatly increases the complexity of product replacement, and will cause damage to the surrounding area or the inside of the product, thereby affecting the aesthetics of the product.

[0024] Figure 1 FIG. 1 shows a schematic structural diagram of a controller disclosed in the present application. Figure 1It can be clearly seen that the controller 10 is composed of a back plate 100 and a control box body 200. The back plate 100 is installed at the target position in a detachable manner. For example, the back plate 100 can be installed on the wall in the form of a threaded connection through a threaded hole 130 by means of a bolt (not shown). Specifically, the back plate 100 is provided with an opening 110 and a stop groove 120 connected to the opening 110. In addition, the control box body 200 is provided with a buckle structure 210 on the side facing the back plate 100, and the buckle structure 210 can slide into the stop groove 120 through the opening 110 and be firmly clamped on the stop groove 120. It should be noted that the controller of the present application advantageously connects the control box body and the back plate together through the design of the buckle structure, which can not only improve the installation efficiency of the controller, but also has a good installation fit and a high fault tolerance rate, and does not affect the aesthetics of the product. When disassembling, the control box body and the back plate can be separated by simply withdrawing the buckle structure from the opening without using any tools.

[0025] In such Figure 1 In the illustrated embodiment, the number of the openings 110 and the stop grooves 120 are both three, and the size and shape of the three openings 110 are not specifically limited herein. In addition, the buckle structure 210 includes three bosses 211 corresponding to the three openings 110, and the three bosses 211 are all fixed on the control box body 200, that is, the inner sides of the three bosses 211 are respectively in contact with the surface of the control box body 200 (here, "inside" means a side close to the control box body 200), and the widths of the three bosses 211 are respectively the same as the widths of the three stop grooves 120, and the outer sides of the three bosses 211 are respectively provided with limiting protrusions 212 (here, "outside" means a side away from the control box body 200), and the size of the limiting protrusions 212 is set to be able to pass through the openings 110 and when the buckle structure 210 slides into the stop grooves 120 through the openings 110, the limiting protrusions 212 are in contact with the back plate 100. Further, the size, position and shape of the three bosses 211 can be designed according to actual conditions. For example, at least two of the three bosses 211 have the same size and are symmetrically arranged relative to the center line of the control box body 200. For another example, at least one of the three bosses 211 is located at the middle of the bottom of the control box body 200. For another example, the three bosses 211 and the limiting protrusions 212 on their outer sides are designed to be integrally formed.

[0026] In order to enhance the structural strength of the buckle structure 210, the three bosses 211 are respectively provided with reinforcing ribs 213. Figure 2The reinforcing rib 213 may be provided with an inclined surface inclined relative to the surface of the control box body 200. Of course, for the purpose of facilitating manufacturing, it is also feasible to omit the reinforcing rib from at least one of the three bosses 211, such as Figure 3 shown.

[0027] In addition, considering the possibility that the wall surface on which the back panel is installed is uneven, in order to ensure that the control box body is flush with the wall surface, the portion of the back panel 100 where the opening 110 is provided is provided with a boss 111 (see Figure 1 ), and the portion of the control box body 200 where the buckle structure 210 is provided is provided with a recess 220 matching the boss 111.

[0028] Continue to refer Figure 1 The anti-recoil groove 120 can be located in the middle of the bottom of the opening 110, so that when the operator installs the control box body 200, he only needs to slide the buckle structure 210 downward through the opening 110 into the anti-recoil groove 120 and snap it onto the anti-recoil groove 120.

[0029] As an example, the back plate 100 may be made of a zinc-plated alloy material. It is known to those skilled in the art that the zinc-plated alloy material has the advantages of being strong and durable, not easy to deform, and low cost. In addition, the buckle structure 210 may be made of materials such as plastic.

[0030] Several specific implementations are listed above to explain the controller of the present application in detail. These examples are only used to illustrate the principles and implementation methods of the present application, but not to limit the present application. Without departing from the spirit and scope of the present application, ordinary technicians in this field can also make various modifications and improvements. Therefore, all equivalent technical solutions should belong to the scope of the present application and be defined by the claims of the present application.
