Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a frame for a display module and a display module. Background Technology

[0002] With the development of flat panel display technology, display modules are being used more and more widely. Display modules come in various types, such as liquid crystal display (LCD), organic light-emitting diode (OLED), electroluminescent (EL), and plasma display (TOP). When assembling display modules into a finished display, a fixing frame assembly is required to secure the display modules.

[0003] Display modules typically consist of a support frame and tempered glass. The tempered glass is mounted on the support frame. However, existing tempered glass is fixed to the support frame using glass clamps and limiting frames. To ensure the stability of the tempered glass installation, the glass clamps need to be fixed to the support frame with screws. Since there are multiple glass clamps spaced around the inner circumference of the support frame, each glass clamp must be fixed to the support frame with screws before the tempered glass can be installed. This greatly increases the complexity of tempered glass installation and cannot guarantee the ease of installation. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, this application provides a frame for a display module and a display module.

[0005] The technical solution provided in this application for a display module frame and a display module is as follows: A frame for a display module includes an outer frame and a back plate. The inner side of the outer frame is provided with a mounting part, and the inner side of the back plate is provided with a sheet metal pressure plate. The mounting part and the sheet metal pressure plate are fitted together, and the inner sides of both are provided with mounting grooves for mounting a glass panel. The top surface of the mounting part is slidably mounted on the inner top surface of the outer frame. The top surface of the mounting part is provided with a fastener, which is connected to a fastener groove on the inner top surface of the outer frame. The bottom inner side of the mounting part is provided with an upper groove for placing the glass panel. The top of the sheet metal pressure plate is fitted with the upper groove to form a mounting groove. The sheet metal pressure plate adopts an L-shaped structure, including a horizontal plate and a vertical plate. The top surface of the horizontal plate is fitted with the bottom surface of the mounting part, and the mounting part can slide on the top of the horizontal plate. The vertical plate is fitted with the inner side of the outer frame, and the free end of the vertical plate is detachably connected to both the outer frame and the back plate.

[0006] Furthermore, the mounting groove adopts a U-shaped groove. The upper side of the U-shaped groove adopts the first limiting section of the upper groove body, the lower side adopts the second limiting section of the horizontal plate of the sheet metal pressure plate, and the bottom surface of the U-shaped groove adopts the third limiting section of the upper groove body. The first and second limiting sections are connected to the top and bottom surfaces of the glass panel, respectively, and the third limiting section contacts the side surface of the glass panel. The first and second limiting sections have a protrusion at the end near the main body of the glass panel. The outer side of the protrusion has an arc transition, and the inner side of the protrusion has a strip groove filled with a buffer. An integrally formed mounting block is formed on the inner side of the outer frame. The mounting block and the inner top surface of the outer frame form a space for the mounting part to slide. An integrally formed locking rod perpendicular to the back plate is formed on the edge of the back plate. The locking rod passes through the mounting block and abuts against the side of the mounting part near the outer frame. The contact surface between the mounting part and the locking rod is an inclined surface facing the mounting block, and the free end of the locking rod has an action surface adapted to the inclined surface. An L-shaped mounting plate is also installed on the inside of the back panel. One end of the L-shaped mounting plate is attached to the vertical plate of the sheet metal pressure plate, and the other end is detachably connected to the positioning block on the inside of the back panel.

[0007] Furthermore, the mounting section has a mounting cavity, and a mounting bracket is provided inside the mounting cavity. The upper and lower ends of the mounting bracket are connected to the mounting groove on the inner wall of the mounting cavity through shock-absorbing springs.

[0008] A display module includes a frame for display modules as described above, and also includes a display panel, a backlight module, and a control module, wherein the display panel is installed between a horizontal plate of a sheet metal pressure plate and an L-shaped mounting plate, the backlight module is located inside the back plate, and the control module is detached and installed in the mounting cavity.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. This application forms a U-shaped mounting groove by connecting the mounting part on the inner side of the outer frame with the sheet metal pressure plate on the inner side of the back panel, which can quickly position the glass panel without screws.

[0012] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0013] This application discloses a frame for a display module and a display module.

[0014] Reference Figure 1 and Figure 2A frame for a display module includes an outer frame 1 and a back plate 2. The inner side of the outer frame 1 is provided with a mounting part 3, and the inner side of the back plate 2 is provided with a sheet metal pressure plate 4. The mounting part 3 and the sheet metal pressure plate 4 are fitted together, and the inner sides of both are provided with mounting grooves 35 for mounting a glass panel 5. The top surface of the mounting part 3 is slidably mounted on the inner top surface of the outer frame 1. The top surface of the mounting part 3 is provided with a buckle 31, which is connected to a buckle groove 11 on the inner top surface of the outer frame 1. The bottom inner side of the mounting part 3 is provided with an upper groove 32 for placing the glass panel 5. The top of the sheet metal pressure plate 4 is fitted with the upper groove 32 to form the mounting groove 35. The sheet metal pressure plate 4 adopts an L-shaped structure, including a horizontal plate 41 and a vertical plate 42. The top surface of the horizontal plate 41 is fitted with the bottom surface of the mounting part 3, and the mounting part 3 can slide on the top of the horizontal plate 41. The vertical plate 42 is fitted with the inner side of the outer frame 1, and the free end of the vertical plate 42 is detachably connected to both the outer frame 1 and the back plate 2. When assembling the display module frame, first prepare the outer frame 1 and back plate 2. The mounting part 3 on the inner side of the outer frame 1 is positioned by the fastener 31 on the top surface engaging with the fastener groove 11 on the inner top surface of the outer frame 1. Next, place the glass panel 5 in the upper groove 32 at the bottom inner side of the mounting part 3. Then, attach the top surface of the horizontal plate 41 of the sheet metal pressure plate 4 to the bottom surface of the mounting part 3. Since the mounting part 3 can slide on the top of the horizontal plate 41, its relative position to the sheet metal pressure plate 4 can be adjusted by sliding the mounting part 3, so that the top of the sheet metal pressure plate 4 and the upper groove 32 cooperate to form a complete mounting groove 35, thereby confining the glass panel 5 within the mounting groove 35. At this time, the bottom of the mounting groove 35 does not clamp the glass panel 5, and the glass panel 5 is in a horizontally movable state within the mounting groove 35. Finally, connect the free end of the vertical plate 42 of the sheet metal pressure plate 4 to the outer frame 1 and back plate 2 to complete the entire installation process of the glass panel 5. When it is necessary to remove the glass panel 5, simply reverse the operation: first disconnect the vertical plate 42 from the outer frame 1 and the back plate 2, then slide the mounting part 3 to remove the glass panel 5.

[0015] Reference Figure 1 and Figure 2The mounting groove 35 adopts a U-shaped groove. The upper side of the U-shaped groove adopts the first limiting segment 321 in the upper groove body 32, and the lower side adopts the second limiting segment 411 of the horizontal plate 41 in the sheet metal pressure plate 4. The bottom surface of the U-shaped groove adopts the third limiting segment 322 in the upper groove body 32. The first limiting segment 321 and the second limiting segment 411 are connected to the top and bottom surfaces of the glass panel 5, respectively, and the third limiting segment 322 contacts the side surface of the glass panel 5. The first limiting segment 321 and the second limiting segment 411 are provided with a protrusion 6 near the main body of the glass panel 5. The outer side of the protrusion 6 adopts an arc transition 61, and the inner side of the protrusion 6 is provided with a strip groove 62, which is filled with a buffer 63. An integrally formed mounting block 12 is formed on the inner side of the outer frame 1, wherein the mounting block 12 and the inner top surface of the outer frame 1 form a space for the mounting part 3 to slide. An integrally formed locking rod 21 perpendicular to the back plate 2 is formed on the edge of the back plate 2, wherein the locking rod 21 passes through the mounting block 12 and abuts against the side of the mounting part 3 near the outer frame 1. The contact surface between the mounting part 3 and the locking rod 21 is an inclined surface 33 facing the mounting block 12, wherein the free end of the locking rod 21 has an action surface 211 adapted to the inclined surface 33. An L-shaped mounting plate 22 is also installed on the inner side of the back plate 2, wherein one end of the L-shaped mounting plate 22 is attached to the vertical plate 42 of the sheet metal pressure plate 4, and the other end is detachably connected to the positioning block 23 on the inner side of the back plate 2. When assembling the display module, the U-shaped groove structure is first used to achieve precise positioning and buffer protection of the glass panel 5. Specifically, the upper side of the U-shaped groove is formed by the first limiting segment 321 in the upper groove body 32, the lower side is formed by the second limiting segment 411 of the sheet metal pressure plate 4 horizontal plate 41, and the bottom surface of the groove is the third limiting segment 322 in the upper groove body 32. During assembly, the first limiting segment 321 is in contact with the top surface of the glass panel 5, the second limiting segment 411 is in contact with the bottom surface of the glass panel 5, and the third limiting segment 322 is in contact with the side of the glass panel 5. At the same time, the protrusion 6 provided at the end of the first limiting segment 321 and the second limiting segment 411 near the main body of the glass panel 5 will have a buffer 63 filled in the inner strip groove 62, which will contact the glass panel 5 to form a buffer protection. The arc transition 61 on the outer side of the protrusion 6 can prevent scratches on the glass panel 5.Next, the outer frame 1 and the mounting part 3 are slidably positioned and locked. Specifically, the mounting block 12, which is integrally formed on the inner side of the outer frame 1, forms a space between the mounting part 3 and the inner top surface of the outer frame 1. The mounting part 3 can slide and adjust its position along this space. Then, the locking rod 21, which is integrally formed on the edge of the back plate 2, passes through the mounting block 12. At this time, the free end of the locking rod 21 abuts against the side of the mounting part 3 near the outer frame 1. Since the contact surface between the mounting part 3 and the locking rod 21 is an inclined surface 33 facing the mounting block 12, and the free end of the locking rod 21 has an action surface 211 that matches the inclined surface 33, the action surface 211 on the locking rod 21 can cooperate with the inclined surface 33 when it is installed, driving the mounting part 3 to move, thereby clamping and fixing the glass panel 5 installed in the mounting groove 35 of the mounting part 3. The two are adapted to enhance the locking stability and ensure that the position of the glass panel 5 is fixed. Before the back panel 2 is installed with the outer frame 1, the inner side of the back panel 2 is first fixed. First, one end of the L-shaped mounting plate 22 installed on the inner side of the back panel 2 is attached to the vertical plate 42 of the sheet metal pressure plate 4, and the other end is fixed to the positioning block 23 on the inner side of the back panel 2 with screws to further reinforce the position of the sheet metal pressure plate 4. Then, the back panel 2, the sheet metal pressure plate 4 and the mounting block 12 are fixed with screws. If disassembly is required, the operation is reversed. First, remove the screws that fix the back panel 2, the sheet metal pressure plate 4 and the mounting block 12. After removing the back panel 2, remove the connection between the L-shaped mounting plate 22 and the positioning block 23, and loosen the locking rod 21. The glass panel 5 can be removed by sliding the mounting part 3.

[0016] Furthermore, the mounting section 3 has a mounting cavity 34, and a mounting bracket 341 is provided inside the mounting cavity 34. The upper and lower ends of the mounting bracket 341 are connected to the mounting groove 35 on the inner wall of the mounting cavity 34 via shock-absorbing springs 342. When assembling the mounting section 3 of the display module frame, firstly, a suitable mounting bracket 341 is placed in the pre-set mounting cavity 34 inside the mounting section 3, ensuring that the size of the mounting bracket 341 matches the space of the mounting cavity 34; then, the pre-cut mounting groove 35 on the inner wall of the mounting cavity 34 and the corresponding connection positions of the upper and lower ends of the mounting bracket 341 are located, and one end of the shock-absorbing spring 342 is fixed to the connection points of the upper and lower ends of the mounting bracket 341, and the other end is installed and fixed to the mounting groove 35 on the inner wall of the mounting cavity 34, so that the mounting bracket 341 is suspended and connected in the mounting cavity 34 via the two sets of upper and lower shock-absorbing springs 342. When the display module vibrates during operation, the vibration experienced by the mounting bracket 341 is transmitted to the damping spring 342. The damping spring 342 absorbs the vibration energy through its own elastic deformation, and in conjunction with the damper installed on the damping spring 342, it reduces the vibration and protects the mounting bracket 341 and the electrical components on it, thus achieving a vibration reduction and protection effect. If subsequent maintenance or replacement of the mounting bracket 341 and the damping spring 342 is required, simply open the corresponding inspection structure of the mounting part 3, disconnect the connection between the damping spring 342 and the mounting slot 35 and the mounting bracket 341, and the mounting bracket 341 can be removed for operation. After the operation is completed, reassemble it by reversing the steps.

[0017] A display module includes a frame for a display module as described above, and further includes a display panel 7, a backlight module 8, and a control module 9. The display panel 7 is mounted between the horizontal plate 41 and the L-shaped mounting plate 22 of a sheet metal pressure plate 4. The backlight module 8 is located inside the back plate 2. The control module 9 is detachably installed in a mounting cavity 34. When assembling the display module, the display panel 7 is first installed based on the already assembled display module frame. Specifically, the display panel 7 is placed or fixed to the bottom of the horizontal plate 41 of the sheet metal pressure plate 4 with screws. The position is adjusted so that the edge of the display panel 7 fits against the L-shaped mounting plate 22. Utilizing the structure where one end of the L-shaped mounting plate 22 fits against the vertical plate 42 of the sheet metal pressure plate 4 and the other end is detachably connected to the positioning block 23 inside the back plate 2, the L-shaped mounting plate 22 further limits the display panel 7. Positioned between the sheet metal pressure plate 4, horizontal plate 41, and L-shaped mounting plate 22, ensuring the stability of the display panel 7; before installing the display panel 7, first install the backlight module 8 on the back plate 2. Specifically, place the backlight module 8 in the corresponding area inside the back plate 2, so that it is opposite to the position of the display panel 7. Then, fix the L-shaped mounting plate 22 to the positioning block 23 with screws. The L-shaped mounting plate 22 and the back plate 2 fix the backlight module 8, ensuring that the backlight module 8 can provide a uniform light source for the display panel 7. When installing the control module 9, open the corresponding access structure of the mounting part 3 in the display module frame, align the control module 9 with the mounting cavity 34 in the mounting part 3, and detach the control module 9 in the mounting cavity 34. At the same time, ensure that the wiring connection between the control module 9 and the display panel 7 and the backlight module 8 is normal to realize the transmission of signals and power, and facilitate subsequent maintenance or replacement of parts.

[0018] Working principle: First, the mounting part 3 is slidably mounted on the inner top surface of the outer frame 1 by engaging the buckle 31 on its top surface with the buckle groove 11 on the inner top surface of the outer frame 1. At this time, the upper groove 32 on the inner bottom of the mounting part 3 is opposite to the top of the horizontal plate 41 of the sheet metal pressure plate 4 on the inner side of the back plate 2. Then, the glass panel 5 is placed into the upper groove 32. Since the mounting groove 35 is a U-shaped groove, its first limiting section 321 and second limiting section 411 are connected to the top and bottom surfaces of the glass panel 5, respectively, and the third limiting section 322 contacts the side of the glass panel 5. The protrusion 6 and the internal buffer 63 of the first limiting section 321 and the second limiting section 411 near the main body of the glass panel 5 can play a buffering and limiting role. Next, the vertical plate 42 of the sheet metal pressure plate 4 is attached to the inner side of the outer frame 1, and the vertical plate 42 is connected to the outer frame 1 and the back plate 2 by screws through its free end, so that the top of the sheet metal pressure plate 4 and the upper groove 32 cooperate to form a complete mounting groove 35, fixing the glass panel 5. During this process, the locking rod 21 on the edge of the back plate 2 passes through the mounting block 12 and abuts against the side of the mounting part 3 near the outer frame 1. Since the contact surface between the mounting part 3 and the locking rod 21 is an inclined surface 33, and the action surface 211 of the free end of the locking rod 21 is adapted to the inclined surface 33, the locking rod 21 can drive the mounting part 3 to move, thereby clamping the glass panel 5. Before the back plate 2 is fixedly installed to the outer frame 1, the backlight module 8 is installed inside the back plate 2, the display panel 7 is installed between the horizontal plate 41 of the sheet metal pressure plate 4 and the L-shaped mounting plate 22, and the control module 9 is disassembled and installed in the mounting cavity 34 of the mounting part 3. The shock-absorbing springs 342 at the upper and lower ends of the mounting bracket 341 are connected to the mounting groove 35 on the inner wall of the mounting cavity 34 to play a shock-absorbing and protective role.

[0019] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
