Description

Technical Field

[0001] This application belongs to the field of display technology, and more specifically, relates to a screen reinforcement device. Background Technology

[0002] With the rapid development of display technology, the screen size of various electronic devices (such as tablet computers) is increasing and the bezels are becoming narrower, which places higher demands on the structural stability of the screen. Especially in scenarios such as portable devices, industrial control frames, and public information terminals, the screen often needs to withstand external forces such as vibration during transportation, frequent touch operations, or accidental compression.

[0003] In existing technologies, screens are typically directly glued to the frame. If the glue is misaligned, the adhesive is extremely strong, making disassembly almost impossible without damage, which can easily lead to defects in the screen's appearance. Moreover, if the screen or frame has defects, the inability to separate the components makes repair difficult, often resulting in the scrapping of the entire set of materials and a significant waste of resources. Utility Model Content

[0004] The purpose of this application is to provide a screen reinforcement device to solve the technical problems in the prior art where the screen cannot be disassembled without damage and is difficult to repair, resulting in material waste.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A screen reinforcement device is provided, comprising a face frame and multiple reinforcement mechanisms. The screen is located within the face frame, and the front of the screen abuts against the face frame. Multiple reinforcement mechanisms are installed within the face frame and located around the perimeter of the screen. Each reinforcement mechanism includes a mounting base, a pressure rod, and a driving component. The mounting base is connected to the face frame. The pressure rod is movably connected to the mounting base and has a pressed state and an open state. In the pressed state, the pressure rod abuts against the back of the screen; in the open state, the pressure rod is separated from the back of the screen. The driving component drives the pressure rod to move, thereby switching the pressure rod between the pressed state and the open state.

[0006] Furthermore, the driving component includes a knob and a push rod. The knob is rotatably connected to the mounting base, and the first end of the push rod is threadedly connected to the knob. When switching from the open state to the pressed state, the second end of the push rod is threadedly connected to the mounting base and abuts against the pressure rod.

[0007] Furthermore, one end face of the knob is provided with a hook, and the inner side of the mounting base is provided with an annular groove, and the hook can rotate in the annular groove.

[0008] Furthermore, the end face of the second end of the push rod is provided with a positioning post, and the pressure rod is provided with a positioning hole. When switching from the open state to the pressed state, the positioning post is inserted into the positioning hole.

[0009] Furthermore, the reinforcement mechanism also includes a first elastic element, which is disposed within the mounting base. One end of the first elastic element abuts against the mounting base, and the other end of the first elastic element abuts against the pressure rod.

[0010] Furthermore, in the open state, the lever has a first position and a second position; in the first position, the lever is located directly behind the screen, and in the second position, the lever is located to the side of the screen; the driving member can drive the lever to move so that the lever switches between the first position and the second position.

[0011] Furthermore, the driving component also includes a spring, a second elastic element, and two connecting rods. The connecting rods have a limiting ring protruding from their sides at their midpoints. The first end of the connecting rod is movably disposed within the knob, and the first end of the limiting ring abuts against the knob. The second elastic element is sleeved on the second end of the connecting rod. One end of the second elastic element abuts against the second end of the limiting ring, and the second end of the second elastic element abuts against the mounting base. The spring is engaged within the knob, with its midpoint abutting against the end face of the first end of the push rod, and both ends of the spring abutting against the first ends of the two connecting rods respectively. In the open state, the spring pushes the two connecting rods to move, so that the second ends of the two connecting rods are respectively located on both sides of the pressure rod.

[0012] Furthermore, the knob is provided with a support rod, the support rod has a stepped surface, and the spring piece is provided with a limiting hole; the support rod is inserted into the limiting hole, and the spring piece abuts against the stepped surface.

[0013] Furthermore, the side of the pressure bar facing the screen is covered with a first flexible layer.

[0014] Furthermore, the reinforcement device also includes multiple limiting brackets, which are installed inside the face frame and located around the screen, abutting against the sides of the screen.

[0015] The beneficial effects of the screen reinforcement device provided in this application are as follows: Compared with the prior art, this application effectively solves the technical pain points of cumbersome operation and difficult maintenance of existing screen reinforcement methods. Specifically, the reinforcement device controls the pressure rod to switch between a clamped state and an open state through a driving component, realizing the rapid installation and removal of the screen. In the clamped state, the pressure rod firmly abuts against the back of the screen, forming a reliable clamping force together with the frame, ensuring the screen remains stable under vibration or impact; no glue is needed for fixing. In the open state, the driving component drives the pressure rod to quickly detach from the back of the screen, and the user can directly remove or insert the screen from the frame without the need for special tools such as screwdrivers. The operation is simple and significantly improves the efficiency of installation, replacement, or repair; at the same time, the screen can also be adjusted during installation, reducing the scrap rate and saving production costs.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] Please refer to the following: Figure 1 and Figure 3 The screen reinforcement device provided in this application embodiment will now be described. This screen reinforcement device includes a frame 100 and multiple reinforcement mechanisms 200. The screen 300 is located within the frame 100, and the front of the screen 300 abuts against the frame 100. The multiple reinforcement mechanisms 200 are installed within the frame 100 and are located around the screen 300. Each reinforcement mechanism 200 includes a mounting base 201, a pressure rod 202, and a driving component. The mounting base 201 is connected to the frame 100; the pressure rod 202 is movably connected to the mounting base 201, such as... Figure 2 and Figure 4 As shown, the lever 202 has a pressed state and an open state. In the pressed state, the lever 202 abuts against the back of the screen 300, and in the open state, the lever 202 is separated from the back of the screen 300. The driving member is used to drive the lever 202 to move so that the lever 202 switches between the pressed state and the open state.

[0039] The screen reinforcement device provided in this application embodiment effectively solves the technical pain points of cumbersome operation and difficult maintenance of existing screen reinforcement methods compared with the prior art. Specifically, the reinforcement device controls the pressure rod 202 to switch between a clamped state and an open state through a driving component, realizing the rapid installation and removal of the screen 300. In the clamped state, the pressure rod 202 firmly abuts against the back of the screen 300, forming a reliable clamping force together with the frame 100, ensuring that the screen 300 remains stable under vibration or impact; no glue is needed for fixing. In the open state, the driving component drives the pressure rod 202 to quickly detach from the back of the screen 300, and the user can directly remove or insert the screen 300 from the frame 100 without the need for special tools such as screwdrivers. The operation is simple and significantly improves the efficiency of installation, replacement or maintenance; at the same time, the screen 300 can also be adjusted during installation, reducing the scrap rate and saving production costs.

[0040] In this embodiment, the specific number of reinforcing mechanisms 200 can be adjusted according to the size of the screen 300. For example, 8-12 reinforcing mechanisms 200 can be set in a large screen 300, evenly distributed on the top, bottom, left, and right sides of the screen 300 to ensure balanced pressure on the edges of the screen 300 and avoid excessive local stress that could cause deformation of the screen 300. For a small screen 300, 4 reinforcing mechanisms 200 (1 on each side) are sufficient to meet the stability requirements. The mounting base 201 can be connected to the frame 100 by snap-fit ​​or screw fixing. Snap-fit ​​connection facilitates pre-installation positioning, while screw fixing can improve the vibration resistance of the overall structure. In practical applications, a suitable connection scheme can be selected according to the usage scenario of the equipment.

[0041] In one embodiment of this application, please refer to the following: Figure 6 and Figure 7 The driving component includes a knob 203 and a push rod 204. The knob 203 is rotatably connected to the mounting base 201, and the first end of the push rod 204 is threadedly connected to the knob 203. When switching from the open state to the pressed state, the second end of the push rod 204 is threadedly connected to the mounting base 201 and abuts against the pressure rod 202.

[0042] In this embodiment, when the user rotates the knob 203 clockwise, the knob 203 drives the push rod 204 to move axially via a threaded transmission. The second end of the push rod 204 gradually screws into the threaded hole of the mounting base 201 until it tightly abuts against the pressure rod 202, thereby pushing the pressure rod 202 to apply pressure to the back of the screen 300, achieving a clamping state. During this process, the linear displacement of the push rod 204 is converted into a stable clamping force of the pressure rod 202, ensuring that the screen 300 is firmly fixed. Conversely, when the user rotates the knob 203 counterclockwise, the second end of the push rod 204 exits from the threaded hole of the mounting base 201, and at the same time, the push rod 204 drives the pressure rod 202 to retract synchronously, so that the pressure rod 202 is completely separated from the back of the screen 300, quickly switching to the open state, facilitating the unobstructed disassembly or installation of the screen 300. This design does not require any external tools; the state switching can be completed simply by rotating the knob 203, significantly improving maintenance efficiency.

[0043] In one embodiment of this application, please refer to Figure 8 The knob 203 has a hook 231 on one end face and an annular groove 211 on the inner side of the mounting base 201. The hook 231 can rotate in the annular groove 211.

[0044] In this embodiment, the hook 231 is embedded in the annular groove 211, forming an axial limit on the knob 203, allowing the knob 203 to rotate circumferentially relative to the mounting base 201 while preventing it from axially disengaging from the mounting base 201. When the knob 203 is rotated, the hook 231 slides circumferentially within the annular groove 211, providing stable support for the knob 203 and ensuring smooth rotation, while effectively preventing axial movement or accidental loosening of the knob 203 during operation. This mating structure of the hook 231 and the annular groove 211 not only achieves a reliable rotational connection of the knob 203 but also facilitates assembly. Assembly is completed simply by aligning the hook 231 of the knob 203 with the annular groove 211 on the mounting base 201 and applying axial pressure, causing the hook 231 to elastically deform and engage with the groove. No additional fasteners are required, further embodying the tool-free assembly and disassembly design concept.

[0045] In one embodiment of this application, please refer to the following: Figure 10 and Figure 12 The end face of the second end of the push rod 204 is provided with a positioning post 241, and the pressure rod 202 is provided with a positioning hole 221. When switching from the open state to the pressed state, the positioning post 241 is inserted into the positioning hole 221.

[0046] In this embodiment, the positioning pin 241 is inserted into the positioning hole 221 to reliably lock the pressure rod 202, ensuring that the pressure rod 202 can firmly fix the screen 300 in the clamped state and prevent loosening or displacement. When switching from the open state to the clamped state, the positioning pin 241 is accurately inserted into the positioning hole 221, providing axial and circumferential constraints to ensure uniform distribution of clamping force; while when switching back to the open state, the positioning pin 241 can be easily pulled out, achieving rapid release.

[0047] In one embodiment of this application, please refer to the following: Figure 8 and Figure 10 The reinforcement mechanism 200 also includes a first elastic element 205, which is disposed in the mounting base 201. One end of the first elastic element 205 abuts against the mounting base 201, and the other end of the first elastic element 205 abuts against the pressure rod 202.

[0048] In this embodiment, the first elastic element 205 provides a continuous restoring force through its elastic deformation. In the loosened state, the first elastic element 205 automatically rebounds, assisting the pressure rod 202 to quickly return to the open position, facilitating one-handed operation by the user. When the push rod 204 moves the pressure rod 202, the first elastic element 205 absorbs the impact and evenly distributes the clamping force, further improving the reliability and durability of the device. Specifically, the first elastic element 205 can be a spring or an elastic rubber body, preferably a fatigue-resistant helical compression spring.

[0049] In one embodiment of this application, please refer to the following: Figure 9 and Figure 11 In the open state, the lever 202 has a first position and a second position; in the first position, the lever 202 is located directly behind the screen 300, and in the second position, the lever 202 is located on the side of the screen 300; the driving member can drive the lever 202 to move so that the lever 202 switches between the first position and the second position.

[0050] In this embodiment, the driving component can smoothly drive the pressure rod 202 from the first position to the second position, achieving rapid avoidance and preventing any physical obstruction when moving out of the screen 300. Specifically, in the first position, although the pressure rod 202 is separated from the screen 300, it is located directly behind the screen 300. When moving out of the screen 300, the pressure rod 202 will still interfere with the screen 300. By moving the pressure rod 202 to the second position through the driving component, the pressure rod 202 is located on the side of the screen 300, and when moving out of the screen 300, the pressure rod 202 will not interfere with the screen 300.

[0051] In one embodiment of this application, please refer to the following: Figure 10 and Figure 12The driving component also includes a spring plate 206, a second elastic element 207, and two connecting rods 208. The middle part of the connecting rod 208 has a limiting ring 281 protruding from the side of the connecting rod 208. The first end of the connecting rod 208 is movably disposed in the knob 203, and the first end of the limiting ring 281 can abut against the knob 203. The second elastic element 207 is sleeved on the second end of the connecting rod 208. One end of the second elastic element 207 abuts against the second end of the limiting ring 281, and the second end of the second elastic element 207 abuts against the mounting base 201. The spring plate 206 is snapped into the knob 203. The middle part of the spring plate 206 abuts against the end face of the first end of the push rod 204, and the two ends of the spring plate 206 abut against the first ends of the two connecting rods 208 respectively. In the open state, the spring plate 206 pushes the two connecting rods 208 to move so that the second ends of the two connecting rods 208 are respectively located on both sides of the pressure rod 202.

[0052] In this embodiment, by setting up a spring piece 206, a second elastic element 207, and two connecting rods 208, rotating the knob 203 can drive the pressure rod 202 to switch between a first position and a second position. Specifically, after the pressure rod 202 separates from the screen 300, continuing to rotate the knob 203 causes the push rod 204 to continue moving, thereby pressing against the spring piece 206. The spring piece 206 bends and deforms, causing displacement at its end, which in turn pushes the connecting rods 208 to move. This places the second ends of the two connecting rods 208 on both sides of the pressure rod 202, allowing the two connecting rods to clamp the pressure rod 202. Continuing to rotate the knob 203 will drive the pressure rod 202 to rotate, thus switching the pressure rod 202 from the first position to the second position.

[0053] Rotating knob 203 in the opposite direction switches the pressure lever 202 from the second position to the first position. Continuing to rotate knob 203 causes push rod 204 to move downwards, gradually releasing the pressure on spring 206. Spring 206 slowly returns to its original position, and connecting rod 208, under the action of the second elastic element 207, also slowly returns to its original position, releasing the constraint on pressure lever 202. Continuing to rotate knob 203 causes push rod 204 to continue moving downwards, pressing against pressure lever 202 and pushing it downwards until pressure lever 202 presses against screen 300.

[0054] Understandably, the mounting base 201 is equipped with a sliding groove 212, the opening of which is L-shaped. The pressure rod 202 can move along the opening of the sliding groove 212. When the pressure rod 202 is at its lowest point, it is in the clamped state. When it is at its highest point, it is in the first position. Rotating the pressure rod 202 90 degrees from the first position reaches the second position. During the process of the pressure rod 202 moving vertically from the lowest point to the highest point, each turn of the knob 203 raises the pressure rod 202 by the height of the screw thread on the push rod 204. This process is relatively slow, which is beneficial for smooth operation and fine-tuning during clamping. When the pressure rod 202 reaches the highest point, during the process of rotating from the first position to the second position, after the push rod 204 is disengaged from the mounting base 201, the knob 203 only needs to be turned 1 / 4 turn to reach the final position, reducing operation time. The varying movement speed of the pressure rod 202 throughout the process meets practical needs.

[0055] In one embodiment of this application, please refer to the following: Figure 10 and Figure 12 The knob 203 has a support rod 232 inside, the support rod 232 has a stepped surface, and the spring piece 206 has a limiting hole; the support rod 232 is inserted into the limiting hole, and the spring piece 206 abuts against the stepped surface.

[0056] In one embodiment of this application, the driving component further includes a limiting pad 209, which is sleeved on the second end of the connecting rod 208 and located between the mounting base 201 and the second elastic member 207. The limiting pad 209 is made of elastic material, which can buffer the impact force between the second elastic member 207 and the mounting base 201, reducing wear on the components during operation and extending the service life of the device. Simultaneously, the limiting pad 209 can also increase the friction between the second elastic member 207 and the mounting base 201, preventing the second elastic member 207 from rotating circumferentially during compression or rebound, ensuring the stability of the movement trajectory of the connecting rod 208, thereby guaranteeing the accuracy and reliability of the switching of the pressure rod 202 between the first and second positions. Furthermore, the limiting pad 209 also provides a certain sealing effect, preventing dust, impurities, etc., from entering the interior of the mounting base 201 and affecting the normal operation of the driving component.

[0057] In this embodiment, by setting the support rod 232, the stepped surface provides a stable support point when the spring piece 206 is bent under force, preventing the spring piece 206 from being excessively deformed or dislodged, and ensuring that the end of the spring piece 206 generates precise displacement.

[0058] In one embodiment of this application, please refer to the following: Figure 10 and Figure 12 The side of the pressure rod 202 facing the screen 300 is covered with a first flexible layer 222.

[0059] In this embodiment, the first flexible layer 222 effectively buffers the direct pressure of the pressure rod 202 on the screen 300, preventing scratches or damage to the surface of the screen 300 during the clamping process, while ensuring uniform pressure distribution and improving reinforcement stability. The first flexible layer 222 is made of elastic materials such as foam, silicone, or rubber, possessing good wear resistance and elastic deformation capabilities. It maintains a close fit with the screen 300 when the pressure rod 202 switches positions, preventing loosening or displacement. Thus, with tool-free operation, the user can reliably clamp and release the screen 300 by rotating the knob 203, protecting the integrity of the screen 300 and simplifying the maintenance process.

[0060] Understandably, the surface of the bezel 100 that contacts the screen 300 is provided with a second flexible layer. This second flexible layer works synergistically with the first flexible layer 222 to provide cushioning protection from both the front and back of the screen 300, further reducing the risk of damage to the screen 300 during installation or in a vibrating environment, while also facilitating the disassembly of the screen 300. The second flexible layer can also fill the tiny gaps between the screen 300 and the bezel 100, reducing the screen 300's movement within the gaps and improving the overall structural stability.

[0061] In one embodiment of this application, please refer to the following: Figure 1 and Figure 5 The reinforcement device also includes multiple limiting brackets 400, which are installed inside the face frame 100. The multiple limiting brackets 400 are located around the screen 300 and abut against the side of the screen 300.

[0062] In this embodiment, by setting a limiting bracket 400, the screen 300 can be positioned from the side, effectively limiting the horizontal displacement of the screen 300 and preventing lateral displacement due to vibration or impact. Multiple limiting brackets 400 are evenly distributed around the screen 300, tightly abutting against the sides of the screen 300 to form multi-directional constraints, ensuring accurate and stable installation of the screen 300 within the frame 100. Simultaneously, the design of the limiting bracket 400 allows for a certain assembly gap, ensuring reliable positioning of the screen 300 without causing deformation of the screen 300's frame due to excessive pressure, further improving the device's safety and adaptability.

[0063] The screen reinforcement device provided in this application operates as follows:

[0064] When installing the screen 300, first place the screen 300 inside the frame 100, ensuring that the front of the screen 300 is in contact with the second flexible layer of the frame 100. At this time, the limiting bracket 400 initially positions the screen 300 from the side. Subsequently, the user rotates the knob 203 of the reinforcing mechanism 200. The driving component moves the pressure rod 202 from the second position (side of the screen 300) in the open state to the first position (directly behind the screen 300). Continuing to rotate the knob 203 clockwise, the push rod 204 applies pressure to the pressure rod 202 through threaded transmission, causing the pressure rod 202 to overcome the elastic force of the first elastic element 205 and move towards the back of the screen 300 until the positioning hole 221 on the pressure rod 202 engages with the positioning post 241 of the push rod 204, and the pressure rod 202 enters the clamping state. At this point, the first flexible layer 222 is in close contact with the back of the screen 300, working in conjunction with the frame 100 to clamp the screen 300. During disassembly, rotating the knob 203 counterclockwise causes the push rod 204 to disengage the pressure rod 202 from the back of the screen 300. The first elastic element 205 rebounds, pushing the pressure rod 202 back to the first position. Continuing to rotate the knob 203 causes the driving element, through the spring 206, connecting rod 208, and other structures, to switch the pressure rod 202 from the first position to the second position, releasing the constraint on the screen 300. The user can then directly remove the screen 300. The entire process requires no tools, is convenient, and the cooperation of the flexible layer and the limiting bracket 400 effectively protects the screen 300 and ensures stable installation.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
