[0026] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is only an interpretation of the present utility model and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.

[0028] Embodiment, as shown in the figure, a remote controller includes a front panel 1, an intermediate housing 2, and a rear cover 3 assembled in sequence from front to back. The front panel 1, the intermediate housing 2, and the rear cover 3 can be integrally formed using conventional plastic materials respectively. The front panel 1 can be set as a rectangular frame structure with rounded corners, and the intermediate housing 2 can be a conventional rectangular box structure. A liquid crystal screen is clamped between the front side of the front panel 1 and the intermediate housing 2, and it can be installed using a conventional installation method. Inside the intermediate housing 2, components such as a circuit board and wires are connected according to the conventional method. The innovative part of this application is mainly on the rear side, specifically: the rear cover 3 includes a base plate 30, and a wire operation opening 301 that extends upward from the bottom position and penetrates through the front and back is formed on the base plate 30. The vertical length of the wire operation opening 301 preferably exceeds half of the vertical length of the base plate 30 and is preferably less than four-fifths. In this way, wires can flow through the wire operation opening 301 and operations such as wiring or connection can be carried out. Further, a wire guiding and strengthening rib plate 32 that extends vertically and arches forward is integrally connected to the front surface of the base plate 30. The wire guiding and strengthening rib plate 32 is located in front of the wire operation opening 301. A hidden wire guiding groove 320 for routing wires from the wall is formed on the rear surface of the wire guiding and strengthening rib plate 32, which extends vertically and is recessed forward in front of the front surface of the base plate 30. Here, the wire guiding and strengthening rib plate 32 plays a role in strengthening the structure. In addition, in order to form the hidden wire guiding groove 320, the hidden wire guiding groove 320 on its rear side cooperates with the wire operation opening 301, and preferably, the hidden wire guiding groove 320 is in communication with the wire operation opening 301 from front to back.The wire operation port 301 has a strip-shaped rectangular structure, that is, the wire operation port 301 has a vertical strip-like style. The bottom of the invisible wire guiding groove 320 and the bottom of the wire operation port 301 can be flush. However, the wire operation port 301 is preferably higher than the invisible wire guiding groove 320, that is, the top of the wire operation port 301 exceeds the top of the invisible wire guiding groove 320. In this way, the wires on the back can pass through the invisible wire guiding groove 320 and the wire operation port 301 upwards and then have a folding space forward to enter the middle housing 2. The exceeding part of the wire operation port 301 can be called a wire turning accommodation port. Because of the large number or relatively thick wires themselves, the wire harnesses are stacked at the bottom of the invisible wire guiding groove 320, the wire operation port 301 and the outer area. At this time, without this accommodation port, it is very difficult for the wire harnesses to enter the middle housing 2 from the top of the invisible wire guiding groove 320. This is where this accommodation port is needed to place and turn the wires. The outer area can be the wire groove of the wall. Then, through such a design, the wires are more suitable for running along the wall wires and the fitting degree will be better. For example, the power cord outside the wire controller and the wires inside form a back wire after being connected on the back side, and the back wire is stuffed into the invisible wire guiding groove 320 and the wire operation port 301, that is, stuffed into the U-shaped groove described later. If there is an exceeding part, it is just placed into the wall groove, so that the wall wires can be run better. The invisible wire guiding groove 320 preferably has a semi-cylindrical shape with the arc surface part facing forward. The diameter of the invisible wire guiding groove 320 is the same as the left-right width dimension of the wire operation port 301. The part where the invisible wire guiding groove 320 and the wire operation port 301 are connected front and back forms a U-shaped groove, and a part of the wire operation port 301 near the top exceeds this U-shaped groove. Two or more U-shaped reinforcing ribs u are integrally connected in the U-shaped groove at intervals up and down. The U-shaped reinforcing ribs u are horizontal and in the same direction as the U-shaped groove. The U-shaped reinforcing ribs u play a role in structural strengthening on the one hand and have a certain squeezing effect on the wire harnesses of the wires on the other hand, reducing the slippage of the wires. That is, the U-shaped reinforcing ribs u perform secondary restraint on the wire harnesses to prevent the wire harnesses from being dragged. The diameter of this limiting convex-shaped reinforcing rib of the U-shaped reinforcing rib is preferably smaller than the diameter of the wire harnesses, that is, the left-right width of the wire operation port 301 is smaller than the diameter of the wire harnesses.

[0029] Furthermore, the base plate 30 is installed and connected with a positioning clamp seat 33 located above the wire operation port 301 for limiting and abutting the wires coming up from the invisible wire guiding groove 320. The positioning clamp seat 33 is preferably detachably connected to the base plate 30. On the one hand, it is convenient for wiring, disassembly and other work. On the other hand, it presses and positions the back wires to prevent pulling.

[0030] Specifically, the positioning card holder 33 includes a positioning plate 331 embedded in the base flat plate 30, and a left wire guiding and limiting block 3321 and a right wire guiding and limiting block 3322 that extend downward and are integrally connected to the front surface of the positioning plate 331 and are abutted against the front surface of the base flat plate 30. The left wire guiding and limiting block 3321 and the right wire guiding and limiting block 3322 extend downward beyond the bottom of the positioning plate 331 and are lower. The left wire guiding and limiting block 3321 and the right wire guiding and limiting block 3322 are arranged at intervals left and right and form a wire harness expansion port 33212 located above the invisible wire guiding groove 320. The left-right interval distance of the wire harness expansion port 33212 is greater than the left-right width dimension of the invisible wire guiding groove 320, so that the wires can be better guided and released inside. After the wires enter from the invisible wire guiding groove 320 and the wire operation port 301 into the interior, they can also be guided and limited by the wire harness expansion port 33212. However, the left-right width dimension of the wire harness expansion port 33212 is larger, allowing the wires to gradually expand inside. In addition, the left wire guiding and limiting block 3321 and the right wire guiding and limiting block 3322 are also for the convenience and stability of the installation of the positioning card holder 33. Since the positioning card holder 33 can just lie on the front side of the base flat plate 30, the left wire guiding and limiting block 3321 and the right wire guiding and limiting block 3322 can adopt a rectangular style or an approximate one, and should preferably be symmetric left and right in mirror image. The bottoms of the left wire guiding and limiting block 3321 and the right wire guiding and limiting block 3322 are preferably located at the middle position above and below the aforementioned wire turning accommodating port, and the left wire guiding and limiting block 3321 and the right wire guiding and limiting block 3322 are respectively located on the left and right sides of the wire operation port 301.

[0031] Further, at least a part of the bottom part of the front surface of the positioning plate 331 serves as a wire pressing part y and is located at a position in front of the wire operation port 301, so that the wires coming up from below can be better squeezed and abutted against after being folded inward, preventing wire pulling. The wire pressing part y performs pressing and limiting from above. Furthermore, the wire pressing part y is located at a position behind the wire harness expansion port 33212, and preferably, the part of the bottom of the positioning plate 331 between the left wire guiding and limiting block 3321 and the right wire guiding and limiting block 3322 serves as the wire pressing part y. Such a setting effect is relatively good.

[0032] Preferably, an embedding hole 300 that penetrates through the front and back and into which the positioning plate 331 is embedded is formed in the base plate 30. The positioning plate 331 is embedded in the base plate 30. The positioning plate 331 is in a convex shape, and a connection hole 3310 that penetrates through the front and back and is used for connecting with the base plate 30 is formed in the upper part of the positioning plate 331. The embedding hole 300 is correspondingly in a convex shape and has a size approximately the same as that of the positioning plate 331, and can be slightly larger. Of course, such a setting cannot ensure the stability of the embedded connection, so the design of the connection hole 3310 is required. The connection hole 3310 is in the upper half of the positioning plate 331. Further, an upper reinforcing plate s1 located on the front side of the upper half of the embedding hole 300 is integrally connected to the front surface of the base plate 30. The upper reinforcing plate s1 is in a rectangular shape or an approximate shape and can preferably cover the upper half of the embedding hole 300 on the front side. On the one hand, this limits the positioning plate 331 on the front side, and at the same time provides a part for connecting with the positioning plate 331. A hole structure corresponding to the connection hole 3310 and penetrating through the front and back can be formed in the upper reinforcing plate s1. In this way, connection structures such as screws can pass through the connection hole 3310 and the holes in the upper reinforcing plate s1 to connect the two. If it is a screw, these holes can be threaded holes. Further, for the firmness of the connection, it can be optimized. Since the thickness of the upper reinforcing plate s1 is not very thick, at most about 2 mm, the length of the screw needs to be longer. Whether it is for its own strength or the strength of the connection, a cylindrical reinforcing column s2 extending forward is integrally connected to the front surface of the upper reinforcing plate s1. The reinforcing column s2 is provided with a hole that communicates with the hole in the upper reinforcing plate s1 from the rear side to the front. In this way, the depth of the hole in the upper reinforcing plate s1 can be extended, so that locking parts such as screws can be more deeply connected to the upper reinforcing plate s1 and the reinforcing column s2 after passing through the connection hole 3310. The cross-sectional dimension of the reinforcing column s2 must be smaller than the plate area of the upper reinforcing plate s1, reducing the space occupancy rate, and at the same time enabling the screw to better perform the locking connection.

[0033] Furthermore, a limiting and reinforcing rib plate 34 is integrally connected to the front surface of the base plate 30 for the front side edge portion of the positioning plate 331 to abut against and be limited. The limiting and reinforcing rib plate 34 is arranged at the peripheral position of the lower half of the positioning plate 331, that is, at the peripheral position of the lower half of the embedding hole 300. The limiting and reinforcing rib plate 34 can be designed as a C-shaped plate and has two pieces, and they are opposite to each other left and right. The C-shaped plates cover a little of the edge portion of the lower half of the positioning plate 331 at the peripheral position on the front side, and the formed shielding portion can also be in a C shape. In this way, the C-shaped plates play a role of abutting and limiting the positioning plate 331 on the front side. When installing the positioning card seat 33, the left wire guiding and limiting block 3321 and the right wire guiding and limiting block 3322 first pass through the embedding hole 300 from back to front. At this time, the positioning card seat 33 is in a lying state. Then, the left wire guiding and limiting block 3321 and the right wire guiding and limiting block 3322 are slowly turned downwards and abutted against the front side of the base plate 30, so that the positioning plate 331 is just vertically embedded into the embedding hole 300. Then, through locking parts such as screws, further locking can be carried out through the connecting holes 3310 and the holes in the front side structure of the base plate 30.

[0034] In addition, the installation of the rear cover 3 on the building surface can be realized through existing connection structures such as bonding or hanging. If it is hanging, hanging installation holes x can be opened on the base plate 30, and three can be arranged at intervals of left, middle and right. The subsequent installation of the middle shell 2 and the rear cover 3 can be in a conventional manner. A connecting column z is integrally connected to each of the four corners inside the middle shell 2. The connecting column z is provided with a hole that runs through from back to front. Corresponding holes that run through from front to back are also opened at the four corner positions of the base plate 30. Then, the middle shell 2 and the base plate 30 can be locked and connected by bolts passing through these corresponding connecting holes. This is also convenient for disassembly and assembly. In addition, a bottom wire outlet hole d can be opened at the bottom of the middle shell 2. For example, in some working conditions where it is not suitable to run the wall wire, or in some installation environments where external wiring is required from the bottom, it can be used more flexibly.

[0035] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or replacements, and these modifications or replacements should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
