Description

Technical Field

[0001] The present invention relates to the technical field of wall-mounted air conditioners, and particularly relates to a fixing device for an air conditioner display module and an air conditioner. Background Art

[0002] An air conditioner usually installs a display module on the back of the air conditioner panel through hooks or screws, which is used to display diagrams such as the temperature, WiFi function, and fresh air function during the operation of the air conditioner in real time. During installation, first, the electronic unit is fixed in the display box to form the display module. Then, one end of the display module is inserted into the corresponding hook groove on the panel with the hook tilted or vertical, and then the hook at the other end is slightly forced into the corresponding hook groove, or the screw holes of the display module are aligned with the screw holes on the panel, and fixed by screwing, and finally the data cable is arranged neatly to complete the installation.

[0003] The fixing methods for fixing the display module on the back of the air conditioner panel usually include three methods: pure hook fixing, screw fixing, and combined fixing of screws and hooks. Among them, the pure hook fixing method of the display module has a complex structure, and the fixing effect of the display box arranged on the back of the air conditioner panel is average. Problems such as loose hook fixing and hook fracture often occur, resulting in the detachment of the display module and product quality problems. The pure screw fixing method of the display module requires at least two screws. Although it can avoid the risk of the display box falling off to a certain extent, its production efficiency is low, the production cost is high, and it is not convenient for the maintenance of the air conditioner display module. The traditional combined fixing method of hooks and screws for the display module is one of the more common fixing methods. However, there are still problems such as a complex hook structure, a risk of the display box falling off, and low production efficiency of screwing.

[0004] Therefore, there is a need for a fixing device for an air conditioner display module that is simple in structure, convenient to operate, firmly fixed, and convenient for the maintenance of the air conditioner display module. Summary of the Invention

[0005] The main purpose of the present invention is to provide a fixing device for an air conditioner display module and an air conditioner, so as to solve the problems of the detachment of the air conditioner display module caused by loose hook fixing, hook fracture, etc. during the fixing process of the air conditioner display module in the prior art, and the problem of low production efficiency caused by the cumbersome operation during the screw installation process, improve the installation efficiency of the air conditioner display module and the stability of the display module fixing, thereby ensuring the overall product quality of the air conditioner, saving labor costs, and increasing economic benefits.

[0006] To achieve the above object, the present invention provides a fixing device for an air conditioner display module, which includes a display board, a first mounting shell, and a second mounting shell. The display board is arranged inside the first mounting shell, and the first mounting shell is sleeved inside the second mounting shell. At least three evenly arranged elastic arms are provided on the outer bottom wall of the first mounting shell, and the bottom ends of the elastic arms are in contact with the inner bottom wall of the second mounting shell. A plurality of limiting ribs are provided on the outer side wall of the first mounting shell, and the limiting ribs are in contact with the inner side wall of the second mounting shell. When the display board is subjected to or releases pressure, the first mounting shell moves up and down inside the second mounting shell.

[0007] Further, a digital display element is arranged on the display board, and positioning holes are provided on the upper and lower sides of the display board.

[0008] Further, hooks are provided on the inner side wall of the first mounting shell, and positioning posts are provided on the inner bottom wall of the first mounting shell near the side wall of the shell. The positioning posts pass through the positioning holes, and the hooks press the display board to install the display board inside the first mounting shell.

[0009] Further, support columns are also provided on the inner bottom wall of the first mounting shell, and a plurality of support feet are provided between the positioning posts and the support columns.

[0010] Further, the elastic arms are in the shape of thin sheets and extend outward from top to bottom.

[0011] Further, a plurality of limiting hooks for limiting the upward movement amount of the first mounting shell are provided on the side wall of the second mounting shell.

[0012] Further, a plurality of limiting notches adapted to the limiting hooks are provided on the side wall of the first mounting shell, and there is a certain distance between the limiting notches and the limiting hooks.

[0013] Further, the display board is connected with a data line, and a wire groove for wiring is provided on the first mounting shell.

[0014] Further, an arc-shaped notch is provided at the position on the side wall of the second mounting shell that is in contact with the wire groove of the first mounting shell.

[0015] The present invention also provides an air conditioner having the fixing device for the air conditioner display module in the above embodiment. The second mounting shell is installed on the middle frame of the indoor unit of the air conditioner, and a digital display window is provided at the position corresponding to the display module on the panel of the indoor unit of the air conditioner.

[0016] The present invention has the following beneficial effects:

[0017] The present invention mounts the display module on the middle frame of the air conditioner indoor unit, and regularizes the data line through the wire slot of the first mounting shell, optimizing the cumbersome steps of first installing the bayonet or screwing the screw, and then regularizing the data line when the display module is installed on the back of the panel, saving the installation time and improving the installation efficiency. Moreover, the fixing effect of the display module is the same as the fastening degree of the traditional screw fixing, ensuring the stability of the display module fixation;

[0018] The first mounting shell of the present invention can move up and down within the second mounting shell. When the panel is closed, the panel presses the first mounting shell, and the pressure of the panel is greater than the elastic force of the elastic arm of the first mounting shell, causing the first mounting shell to move downward, bringing the panel closer to the display board. While ensuring the display effect, it avoids the extrusion of the limiting hook of the second mounting shell by the first mounting shell, increasing the service life of the limiting hook.

[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0029] As Figure 2 shown, an air conditioner display module fixing device 1 includes a display board 11, a first installation shell 12 and a second installation shell 13. The display board 11 is arranged in the first installation shell 12, and the first installation shell 12 is sleeved in the second installation shell 13. As Figure 5 shown, at least three uniformly arranged elastic arms 125 are provided on the outer bottom wall of the first installation shell 12. The bottom ends of the elastic arms 125 are in contact with the inner bottom wall of the second installation shell 13. A plurality of limit ribs 126 are provided on the outer side wall of the first installation shell 12. The limit ribs 126 are in contact with the inner side wall of the second installation shell 13. When the display board is subjected to or releases pressure, the first installation shell 12 moves up and down in the second installation shell 13. The display board 11 and the first installation shell 12 together form a display module, and the structure of the display module is as Figure 6 shown. When the panel 2 is closed, the panel 2 presses the first installation shell 12, and the first installation shell 12 moves downward, so that the panel 2 is in close contact with the display board 11, ensuring the display effect of the display module. When the panel 2 is opened, the first installation shell 12 is supported by the elastic arms 125 to move upward in the second installation shell 13, and the display module is in a convex state relative to the second installation shell 13, facilitating the maintenance of the display board 11. The limit ribs 126 play a role in limiting and guiding the up and down movement of the first installation shell 12 in the second installation shell 13, avoiding the left and right movement of the first installation shell 12 in the second installation shell 13, and ensuring the stability of the installation.

[0030] Specifically, as Figure 3 shown, a digital display element is provided on the display board 11, and positioning holes 111 are provided on the upper and lower sides of the display board 11.

[0031] Specifically, as Figure 4As shown, a hook 121 is provided on the inner side wall of the first mounting shell 12, and a positioning post 122 is provided on the inner bottom wall of the first mounting shell 12 near the side wall of the shell. As Figure 6 shown, the positioning post 122 passes through the positioning hole 111 to limit the installation position of the display board 11 in the first mounting shell 12. The hook 121 presses the display board 11 to install the display board 11 in the first mounting shell 12. The positioning post 122 includes a penetrating portion and a supporting portion. The penetrating portion and the supporting portion are cylindrical. The diameter of the penetrating portion is not greater than the inner diameter of the positioning hole 111, and the diameter of the supporting portion is not less than the inner diameter of the positioning hole 111. When installing the display board 11, first place the display board 11 steadily in the first mounting shell 12 so that the positioning post 122 of the first mounting shell 12 passes through the positioning hole 111 of the display board 11, and then fix the display board 11 through the hook 121 on the side wall of the first mounting shell 12 to prevent the display board 11 from falling off from the first mounting shell 12.

[0032] Specifically, a supporting post 123 is further provided on the inner bottom wall of the first mounting shell 12, and a plurality of supporting feet 124 are provided between the positioning post 122 and the supporting post 123. The supporting post 123 has the same structure as the supporting portion of the positioning post 122. The supporting post 123 and the supporting feet 124 are used to ensure the installation flatness of the display board 11 in the first mounting shell 12 and provide a supporting force for the display board 11 to prevent the display board 11 from breaking when being squeezed.

[0033] Specifically, the elastic arm 125 is in the shape of a thin sheet and extends outward from top to bottom. When the first mounting shell 12 moves downward relative to the second mounting shell 13, the elastic arm 125 is squeezed, and the inclination angle of the elastic arm 125 becomes larger and approaches the horizontal direction. When the panel 2 is opened, the pressure of the first mounting shell 12 on the elastic arm 125 decreases, and the inclination angle of the elastic arm 125 becomes larger and approaches the vertical direction, pushing the first mounting shell 12 to move upward relative to the second mounting shell 13.

[0034] Specifically, a plurality of limit hooks 131 for restricting the upward movement amount of the first mounting shell are provided on the side wall of the second mounting shell 13.

[0035] Specifically, a plurality of limit notches 127 adapted to the limit hooks 131 are provided on the side wall of the first mounting shell 12, and the limit notches 127 and the limit hooks 131 are spaced apart by a certain distance. When the panel 2 is opened, under the action of the elastic arm 125, the first mounting shell 12 moves upward. When the bottom of the limit notch 127 of the first mounting shell 12 contacts the limit hook 131, the first mounting shell 12 is blocked by the limit hook 131. Under the action of the limit hook 131, the first mounting shell 12 stops moving, preventing the first mounting shell 12 from falling off from the second mounting shell 13 and at the same time raising the display board 11 to bulge out from the second mounting shell 13, facilitating the relevant personnel to overhaul the display module.

[0036] Specifically, a data line 112 is connected to the display board 11, and a wire routing groove 128 for wiring is provided on the first mounting case 12. The relevant data lines 112 are regularized through the wire routing groove 128, avoiding the cumbersome steps of regularizing the data lines 112 again when installing and disassembling the data lines 112, saving the installation time and improving the installation efficiency.

[0037] Specifically, an arc-shaped notch is provided at a position on the side wall of the second mounting case 13 that contacts the wire routing groove 128 of the first mounting case 12. When the first mounting case moves up and down within the second mounting case, the wire routing groove 128 also moves up and down within the arc-shaped notch along with the first mounting case.

[0038] In Embodiment 2, different from Embodiment 1, a plurality of guiding grooves adapted to the limiting ribs 126 are provided on the inner side wall of the second mounting case 13. When the first mounting case 12 moves up and down within the second mounting case 13, the limiting ribs 126 of the first mounting case 12 move up and down in the corresponding guiding grooves, further limiting the left and right positions of the first mounting case 12 within the second mounting case 13.

[0039] Embodiment 3

[0040] As Figure 1 shown, an air conditioner uses the air conditioner display module fixing device 1 of Embodiment 1 or Embodiment 2. The second mounting case 13 is mounted on the middle frame 3 of the air conditioner indoor unit. On the panel 2 of the air conditioner indoor unit, a digital display window 21 is provided at a position corresponding to the display module.

[0041] The specific working state of an air conditioner display module fixing device and an air conditioner provided by the present invention is as follows:

[0042] First, the second mounting case 13 is mounted on the middle frame 3 of the air conditioner indoor unit by means of bolts or the like. The display board 11 is mounted into the first mounting case 12 through the positioning posts 122 and the hooks 121 to form a display module. Then, the display module is mounted into the second mounting case 13, and the data line 112 is connected to the display board 11 through the wire routing groove 128. Finally, the air conditioner panel 2 is closed.

[0043] When the air conditioner panel 2 is closed, the panel 2 presses the first mounting case 12. The pressure of the panel 2 is greater than the elastic force of the elastic arm 125. Under the action of the limiting ribs 126, the first mounting case 12 moves vertically downward relative to the second mounting case 13, and the panel 2 is close to the display board 11, ensuring the display effect.

[0044] When the display module needs to be repaired or replaced, open the air conditioner panel 2. Under the action of the elastic arm 125, the first mounting shell 12 moves upward until the limit bayonet 127 of the first mounting shell 12 fits with the limit hook 131 of the second mounting shell 13. At this time, the first mounting shell 12 stops moving. While preventing the first mounting shell 12 from falling off, it makes the display board 11 protrude relative to the second mounting shell 13, facilitating the repair and replacement of the display board 11. At the same time, the data line 112 is arranged in the wiring groove 128. When disassembling or installing the data line 112 of the display board 11, there is no need to re-arrange the data line 112 again, saving the installation time and improving the installation efficiency.

[0045] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
