Description

Technical Field

[0001] This utility model relates to the technical field of home appliance display screens, and in particular to a display module. Background Technology

[0002] The displays of household appliances such as washing machines and dishwashers are gradually developing towards ultra-realistic display and ultra-thin design. The existing basic components include a circuit board, a frame, and a housing. The circuit board is first fixed inside the frame, and then the frame is fixed to the housing. The touch and display circuits are separated. The touch part is a flexible PCB, which is set below the display part, including the light source. The inner side of the glass is the touch film, followed by the PCB and the light source.

[0003] To address the waterproofing issues of existing displays, prior art CN202322528985.2 discloses an ultra-thin module display screen, comprising a housing and an ultra-thin display module. A through window is formed in the housing, and a retaining ring is set around the window on the inner side of the housing. The ultra-thin display module is disposed within the retaining ring, and a waterproof layer is formed by potting adhesive within the retaining ring and on the ultra-thin display module. In this prior art, the ultra-thin display module is directly clipped onto the housing, saving the need for a traditional frame, reducing costs, and decreasing thickness, thus saving installation space in appliances and improving production efficiency. The potting method for fixing the ultra-thin display module significantly improves the waterproofing effect, especially for appliances prone to water ingress such as washing machines and dishwashers. It maximizes the prevention of water damage to the ultra-thin display module with circuit boards, reducing the possibility of internal circuit damage and ensuring the touchscreen function.

[0004] Although the aforementioned existing technology uses glue to fix the ultra-thin display module, when the quality of the product is inspected by lighting up the display module before subsequent product shipment, if any defects are found, even if the defect is just a black spot or other undesirable phenomenon, the display module needs to be repaired. The installation method of directly glued the ultra-thin display module to the housing after glue application means that the glue and clips need to be removed during maintenance. However, the glue and clips are completely bonded, making it difficult to peel off the glue, and the display module is easily damaged during disassembly. Utility Model Content

[0005] The purpose of this invention is to provide a display module that solves the problem of difficulty in disassembling a display module when it has defects, making it easier to disassemble a defective display module and avoiding damage to the display module during the disassembly process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a display module, including a mounting plate, a control panel, a fixing bracket, and a back cover plate. The mounting plate has a mounting opening, which accommodates a display screen electrically connected to the control panel. The back cover plate is located on the rear side of the mounting plate and forms a receiving cavity with the mounting plate to accommodate the fixing bracket and the control panel. The control panel is located on the fixing bracket, and the fixing bracket and the mounting plate are detachably connected by a first fastener to allow for the removal and replacement of the control panel.

[0007] After adopting the above technical solution, this utility model has the following advantages: An installation port is provided on the mounting plate, and the display screen is installed in the installation port, making it convenient for installers or users to view and touch the display module when it is installed on household appliances; the rear cover plate and the mounting plate form a cavity for the mounting bracket and control panel, preventing the bracket and control panel from detaching from the rear of the mounting plate; the control panel is installed on the mounting plate, and then detachably connected to the mounting plate via the bracket. When the display module is inspected before shipment and defects are found, requiring the control panel to be removed from the mounting plate, only the first fastener needs to be tightened to remove the bracket and control panel from the mounting plate, and a new bracket and control panel can be replaced. Compared with the method of potting the ultra-thin display module onto the housing in CN202322528985.2, this reduces the difficulty of disassembling the control panel. Furthermore, during disassembly, only the first fastener between the bracket and the mounting plate is removed, avoiding damage to the display screen and control panel during disassembly, preventing the control panel from being scrapped due to damage during disassembly, and thus reducing the overall cost of the display module.

[0008] Furthermore, the rear side wall of the mounting plate is provided with a first fixing seat, the outer peripheral wall of the fixing bracket is provided with a first positioning member, and the first fastener passes through the first positioning member and is fastened to the first fixing seat to fasten the fixing bracket and control panel on the mounting plate.

[0009] By adopting the aforementioned technical solution, a first positioning element is provided on the outer peripheral wall of the fixed bracket, and then the first positioning element is fastened to the first fixed seat by a first fastener. While fastening the fixed bracket, the first positioning element located on the outside avoids the first fastener from affecting the fixed bracket and the control panel.

[0010] Furthermore, the mounting plate is provided with an auxiliary positioning component, and the fixing bracket is provided with a sleeve component, which engages with the auxiliary positioning component to assist in positioning and fixing the bracket.

[0011] By adopting the aforementioned technical solution, the socket and the auxiliary positioning component are connected to assist in positioning the fixed bracket, avoiding the deflection between the fixed bracket and the mounting plate, and making it easier for installers to install the fixed bracket on the mounting plate using the first fastener, thereby further improving the installation efficiency of the fixed bracket on the mounting plate.

[0012] Furthermore, the rear side wall of the mounting plate is provided with a perimeter, which forms an installation area for accommodating the fixed bracket. The perimeter is provided with a first clearance notch for positioning the fixed bracket, and the outer periphery of the fixed bracket is provided with a first positioning member. The first positioning member is inserted into the first clearance notch to initially position the fixed bracket.

[0013] By adopting the aforementioned technical solution, an installation area for accommodating the fixed bracket is formed on the rear side wall of the mounting plate through the surrounding edge. This facilitates quick positioning of the fixed bracket on the mounting plate by installers. Specifically, when positioning the fixed bracket, the first positioning member can be engaged with the first clearance notch to quickly place the fixed bracket, thereby facilitating the fixing of the fixed bracket to the mounting plate using the first fastener, ensuring the accuracy of the fixed bracket's orientation after fastening. The first positioning member is placed on the outer peripheral wall of the fixed bracket to avoid interfering with the installation of the control panel. In addition, the first clearance notch avoids the first positioning member, ensuring that the front side of the fixed bracket fits against the bottom wall of the installation area, improving the stability of the fixed bracket.

[0014] Furthermore, the end of the first positioning member away from the installation area has an extension portion, the extension portion is provided with a positioning groove facing the installation area, and the outer periphery of the surrounding edge is provided with a positioning rib. The first positioning member is inserted into the first clearance notch and the positioning rib extends into the positioning groove.

[0015] By adopting the aforementioned technical solution, the stability of the fixed bracket is improved when it is not fastened by the first fastener by inserting the positioning groove into the positioning protrusion of the outer perimeter of the surrounding edge, the movement of the fixed bracket during the fastening and installation process is reduced, and the installation efficiency of the installers is further improved.

[0016] Furthermore, the rear cover plate is provided with a second clearance notch to avoid the first positioning member.

[0017] By adopting the aforementioned technical solution, the first positioning component is avoided by the second clearance notch, the space between the front side wall of the rear cover and the rear side wall of the mounting plate is reduced, the possibility of the fixed bracket and control panel shaking in the receiving cavity is reduced, and the stability of the fixed bracket and control panel in the receiving cavity is improved.

[0018] Furthermore, a pressing part is formed between the first positioning member and the fixed bracket, and the back cover plate presses against the pressing part to stabilize the fixed bracket.

[0019] When the back cover is installed on the rear side of the mounting plate, the inner wall of the second clearance notch presses against the pressing part, pressing the fixing bracket against the mounting plate in the front-rear direction, thereby further improving the stability of the fixing bracket on the mounting plate.

[0020] Furthermore, the rear cover plate is provided with a second positioning member, the mounting plate is provided with a second fixing seat, and the second fastener passes through the second positioning member and is fastened to the second fixing seat.

[0021] By adopting the aforementioned technical solution, the alignment of the second positioning component with the second fixing seat facilitates the quick positioning of the back cover plate on the rear side of the mounting plate. When fastening the connection, the second fastener passes through the second positioning component and is fastened to the second fixing seat, ensuring the stability of the back cover plate and facilitating the removal of the back cover plate when the fixing bracket needs to be removed.

[0022] Furthermore, the rear side wall of the mounting bracket is provided with a rim, and the rim is provided with a snap-fit ​​interface. The back cover is provided with a snap-fit ​​rib, which snaps into the snap-fit ​​interface to position the back cover.

[0023] Using the aforementioned technical solution, when installing the back cover on the rear side wall of the mounting plate, the back cover is initially positioned by the snap-fit ​​ribs and the snap-fit ​​interface, which facilitates the installation of the back cover.

[0024] Furthermore, the fixed bracket is provided with a positioning cavity for accommodating the control panel, and a waterproof layer is formed by filling the space between the control panel and the fixed bracket with adhesive.

[0025] By adopting the aforementioned technical solution, a receiving cavity is set on the fixed bracket to facilitate the positioning and installation of the control panel on the fixed bracket. After the control panel is in the positioning cavity, it is connected to the fixed bracket by the formation of glue, so that the glue forms a waterproof layer, improving the waterproof effect of the control panel. After the glue cools, it adheres the control panel to the fixed bracket, improving the stability of the control panel on the fixed bracket. Attached Figure Description

[0039] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0040] like Figure 1 and Figure 2As shown, this utility model provides a display module, including a mounting plate 1, a control panel, a fixing bracket 2, and a rear cover plate 3 (the structure and installation state of the control panel are not shown). The mounting plate 1 has a mounting opening 11, which houses a display screen 4 electrically connected to the control panel. The display screen 4 is used to display the functional information of the household appliance and the currently executed information. The front side of the display screen 4 is flush with the front side of the mounting plate 1 to avoid the possibility of damage to the display screen 4 during stacking or transportation. The rear cover plate 3 is located on the rear side of the mounting plate 1 and forms a receiving cavity 12 with the mounting plate 1 to accommodate the fixing bracket 2 and the control panel. The receiving cavity 12 facilitates the installation of the fixing bracket 2 and the control panel.

[0041] In this embodiment, the control panel is mounted on the fixed bracket 2, and the fixed bracket 2 is detachably connected to the mounting plate 1 via a first fastener. When a defect is detected in the control panel before shipment, the fixed bracket 2 can be disassembled via the first fastener to remove and replace the control panel. Compared with the method of fixing the ultra-thin display module to the housing by potting glue in the prior art CN202322528985.2, this method makes it easier to disassemble and replace the control panel, and it is less likely to damage the control panel and the display screen 4 when disassembling the control panel, thereby reducing the overall cost of the display module. Specifically, as shown... Figure 3 and Figure 4 As shown, the rear side wall of the mounting plate 1 is provided with a first fixing seat 13, and the outer peripheral wall of the fixing bracket 2 is provided with a first positioning member 21. The first positioning member 21 is provided with a through hole 211, and the first fixing seat 13 is provided with a fastening connection hole 131. The first fastener passes through the through hole 211 and is threadedly connected to the fastening connection hole 131, and the rear end of the first fastener abuts against the rear side wall of the first positioning member 21, thereby fastening the fixing bracket 2 to the mounting plate 1. It can be understood that when the bracket 2 is fixed by the fastening connection of the first positioning member 21 and the first fixing seat 13, multiple first positioning members 21 are provided, and the four sides of the fixing bracket 2 are all provided with first positioning members 21. Correspondingly, multiple first fixing seats 13 are also provided, and each of the multiple first positioning members 21 corresponds to one of them. The arrangement of the first positioning members 21 and the first fixing seats 13 being evenly distributed on the four sides of the fixing bracket 2 further improves the stability of the fixing bracket 2 on the mounting plate 1.

[0042] To ensure that the first positioning member 21 and the first fixed seat 13 are aligned in the front-to-back direction, such as Figure 4As shown, the mounting plate 1 is provided with an auxiliary positioning component 14, and the fixed bracket 2 is provided with a sleeve 22. The sleeve 22 is sleeved with the auxiliary positioning component 14 to assist in positioning the fixed bracket 2. When the fixed bracket 2 is placed on the rear side of the mounting plate 1, the sleeve 22 is sleeved with the auxiliary positioning component 14 to position the fixed bracket 2 on the mounting plate 1 before the fixed bracket 2 is tightened. This makes it easier for the first fastener to extend into the fastening connection hole 131, thereby improving the efficiency of the installer in fastening the fixed bracket 2 to the mounting plate 1.

[0043] In another embodiment, such as Figure 6 As shown, the rear side wall of the mounting plate 1 is provided with a surrounding edge 5, which forms an installation area for accommodating the fixing bracket 2. The fixing bracket 2 can be quickly positioned and fixed on the mounting plate 1 through this installation area. Figure 4 and Figure 6 As shown, the perimeter 5 is provided with a first clearance notch 51 for the positioning and fixing bracket 2, and a first positioning element 21 is provided on the outer periphery of the fixing bracket 2. After the fixing bracket 2 is placed in the installation area, the first positioning element 21 is inserted into the first clearance notch 51 to initially position the fixing bracket 2. With the perimeter 5 provided, the first clearance notch 51 facilitates the fastening of the first positioning element 21 to the first fixing seat 13; in this embodiment, as Figure 7 As shown, the front side of the fixed bracket 2 and the front side of the first positioning member 21 are offset in the front-rear direction, and the front side of the first positioning member 21 is located behind the front side of the fixed bracket 2. This ensures that after the fixed bracket 2 is placed in the installation area, the front side of the fixed bracket 2 fits as close as possible to the mounting plate 1, reducing the gap between the fixed bracket 2 and the mounting plate 1 and improving the stability of the fixed bracket 2 on the mounting plate 1. Furthermore, the insertion of the first positioning member 21 into the first clearance notch 51 ensures that the front side of the fixed bracket 2 is as close as possible to the bottom wall of the installation area, thereby reducing the space between the fixed bracket 2 and the mounting plate 1 and improving the stability of the fixed bracket 2 on the mounting plate 1.

[0044] To improve the stability of the first positioning member 21 when it is inserted into the first clearance notch 51, such as Figure 3 and Figure 4 As shown, the first positioning member 21 has an extension 212 at the end away from the installation area. The extension 212 is provided with a positioning groove 213 facing the installation area. The outer periphery of the circumference of the circumference 5 is provided with a positioning rib 52. After the first positioning member 21 is inserted into the first clearance notch 51, the positioning rib 52 is inserted into the positioning groove 213. The insertion of the positioning rib 52 into the positioning groove 213 provides secondary positioning and fixation for the fixed bracket 2, improving the stability of the fixed bracket 2 when the first positioning member 21 is fastened, and preventing the fixed bracket 2 from deflecting when the first fastener is turned.

[0045] In another embodiment, such as Figure 8 and Figure 9As shown, in order to facilitate the installation of the back cover 3, the back cover 3 is provided with a second clearance notch 32 to avoid the first positioning member 21. When the back cover 3 covers the rear side of the fixed bracket 2, it avoids the first positioning member 21 through the second clearance notch 32, so that the front side wall of the back cover 3 abuts against the rear side wall of the fixed bracket 2 as much as possible, reducing the space of the receiving cavity 12, reducing the movement space of the fixed bracket 2 between the mounting plate 1 and the back cover 3, and improving the stability of the fixed bracket 2 and the control panel.

[0046] To improve the stability of the rear cover 3 on the mounting plate 1, such as Figure 9 As shown, the back cover 3 is provided with a second positioning member 31, and the mounting plate 1 is provided with a second fixing seat 15. The second fastener passes through the second positioning member 31 and is fastened to the second fixing seat 15, thereby stably installing the back cover 3 on the rear side of the mounting plate 1. The back cover 3 is fastened by the second fastener, which facilitates the removal of the back cover 3 when the fixing bracket 2 is removed later.

[0047] In another embodiment, such as Figure 9 As shown, to reduce the possibility of the back cover 3 deflecting when fastening it, the rear side wall of the mounting plate 1 is provided with a perimeter 5, and a snap-fit ​​interface 54 is provided on the perimeter 5. The back cover 3 is provided with a snap-fit ​​rib 33, which snaps into the snap-fit ​​interface 54 to position the back cover 3. By snapping the snap-fit ​​rib 33 into the snap-fit ​​interface 54, the possibility of the back cover 3 deflecting when fastening it with the second fastener is reduced, thereby improving the installation efficiency of the back cover 3. More specifically, as... Figure 10 As shown, a pressing part 24 is provided on the outer side wall of the fixed bracket 2. The pressing part 24 extends away from the fixed bracket 2. The first positioning member 21 is located on the end of the pressing part 24 away from the fixed bracket 2. When the back cover plate 3 covers the rear side of the fixed bracket 2, the back cover plate 3 presses against the pressing part 24, which improves the stability of the fixed bracket 2 on the mounting plate 1, and at the same time avoids the gap between the back cover plate 3 and the fixed bracket 2, which would affect the stability of the fixed bracket 2.

[0048] To improve the waterproofing and stability of the control panel on the mounting bracket 2, such as Figure 10 As shown, the fixed bracket 2 is provided with a positioning cavity 23 for accommodating the control panel. Adhesive is poured between the control panel and the fixed bracket 2 to form a waterproof layer. The waterproof layer prevents water from contacting the control panel and improves the waterproof effect of the control panel. After the injected adhesive cools, it adheres to the fixed bracket 2, thereby fixing the control panel to the fixed bracket 2 and improving the stability of the control panel on the fixed bracket 2.

[0049] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
