[0002] With the development and widespread application of industries such as advertising, online games, mobile games, animation, and online education, digital drawing screens (also known as pen screens) have also been widely used in the electromagnetic handwriting industry. Desktop digital drawing screens have become the main tool for professional users such as graphic designers, illustrators, and animators.

[0003] When using a horizontal drawing tablet, the user's hand will inevitably press on the screen. If the overall strength of the product is insufficient, the screen may be pressed and develop blue spots, water ripples, or other defects, resulting in a poor user experience.

[0004] In related technologies, some hand-drawing screen products have built-in metal reinforcement components to improve the overall strength of the device. However, the existing reinforcement structure is difficult to apply to large hand-drawing screens, such as 24-inch and 27-inch screens. Utility Model Content

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1 to 6 As shown, an embodiment of the reinforced screen device of the present invention includes a lower shell 100, a screen module 200, and a reinforcing component.

[0036] Reference Figure 1 , Figure 2 and Figure 3As shown, the lower shell 100 has an upward-facing receiving groove 110, which can be used to receive or connect components such as the screen module 200, wires, circuit boards, and batteries. The following description uses the length direction of the lower shell 100 as the left-right direction, the width direction of the lower shell 100 as the front-back direction, and the thickness direction of the lower shell 100 as the up-down direction as an example.

[0037] Reference Figure 1 , Figure 2 and Figure 3 As shown, the screen module 200 is connected to the upper end of the lower shell 100 to close the receiving groove 110. The lower surface of the screen module 200 and the receiving groove 110 can jointly define the receiving cavity. The receiving cavity can be used to accommodate components such as wires, circuit boards, batteries, and reinforcing components, thereby realizing the hidden arrangement of components such as wires, circuit boards, batteries, and reinforcing components.

[0038] Reference Figure 1 , Figure 2 and Figure 3 As shown, the reinforcing assembly includes two reinforcing plates 300. The two reinforcing plates 300 are located in the middle of the receiving groove 110 and are arranged at intervals along the length of the lower shell 100. The two reinforcing plates 300 are arranged symmetrically about the central axis of the lower shell 100. Both reinforcing plates 300 are located in the receiving groove 110 and are connected to the bottom wall of the receiving groove 110.

[0039] Reference Figure 1 , Figure 2 and Figure 3 As shown in the related technology, some hand-drawn screens have a built-in metal reinforcement component. However, as the product model increases, the area that needs to be supported and subjected to force also increases. That is, as the product increases, the area subjected to force increases, and the metal reinforcement component also increases. However, as the area of ​​the metal reinforcement component gradually increases, the ability of the metal reinforcement component to resist bending deformation decreases. If the force point is concentrated in a certain area, it may lead to excessive local pressure. That is, after the area of ​​the metal reinforcement component increases, there is a defect that it cannot bear sufficient support force, which can easily cause the laminated screen 210 to be pressed with blue spots or water ripples.

[0040] Reference Figure 1 , Figure 2 and Figure 3As shown in the figure, the reinforced screen device provided in this embodiment of the utility model is connected to the lower shell 100 by at least two reinforcing plates 300. With reinforcing plates 300 of equal area, the connection structure of multiple reinforcing plates 300 to the lower shell 100 has better pressure resistance and a larger effective support area, effectively improving the overall strength of the reinforced screen device and reducing the risk of pressure damage to the screen module 200. This reinforced screen device uses two smaller reinforcing plates 300 instead of a single larger hardware reinforcing component, which reduces the mold size of the reinforcing plates 300, thereby reducing mold manufacturing costs and further improving packaging and transportation costs.

[0041] It should be understood that in some other embodiments, the reinforcing component includes three or more reinforcing plates 300, which are arranged at intervals in the left-right direction.

[0042] Reference Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the screen module 200 includes a frame 230, a bonding screen 210, and an adhesive layer 220. The adhesive layer 220 is bonded to the upper surface of the frame 230, and the bonding screen 210 is bonded to the upper end of the adhesive layer 220. That is, the upper and lower ends of the adhesive layer 220 are connected to the bonding screen 210 and the frame 230, respectively, thereby achieving bonding between the bonding screen 210 and the frame 230. The lower end of the frame 230 can be connected to the outer edge of the upper end of the lower shell 100 through a fastener.

[0043] Reference Figure 4 , Figure 5 and Figure 6 As shown, the front and rear edges of the plate 310 are respectively connected to the first reinforcing ribs 320. The two ends of the first reinforcing ribs 320 are arranged in the left and right directions. The setting of the first reinforcing ribs 320 can enhance the stability of the reinforcing plate 300 in the left and right directions, thereby improving the deformation resistance of the first reinforcing ribs 320. This helps to reduce or block the pressure on the screen module 200 after the lower shell 100 is deformed under pressure, thus achieving effective support for the screen module 200 and ensuring the normal display of the screen module 200.

[0044] Reference Figure 4 , Figure 5 and Figure 6 As shown, the two first reinforcing ribs 320 abut against the front and rear edges of the lower end of the frame 230, respectively, to directly support the screen module 200. That is, when the user's hand presses on the screen module 200, the screen module 200 can directly transmit the pressure to the reinforcing plate 300 and the lower shell 100 through the first reinforcing ribs 320, thereby improving the overall strength of the reinforced screen device and effectively reducing the risk of the screen module 200 being damaged by pressure.

[0045] Reference Figure 4 , Figure 5 and Figure 6 As shown, production personnel can assemble the frame 230, the bonding screen 210 and the adhesive layer 220 into a screen module 200, and assemble the reinforcing component and the lower shell 100 together into a lower module. Then, the screen module 200 and the lower module are assembled to realize the assembly of this reinforced screen device.

[0046] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the first reinforcing rib 320 includes a first piece 321 and a second piece 322. The lower edge of the first piece 321 is connected to the edge of the plate 310. The first piece 321 is inclined upwards in a direction away from the plate 310. That is, the first reinforcing rib 320 in front is inclined upwards and forwards, and the first reinforcing rib 320 in the rear is inclined upwards and backwards. The upper edge of the first piece 321 is connected to the lower edge of the second piece 322. The second piece 322 is arranged at right angles to both the screen module 200 and the plate 310.

[0047] Reference Figure 4 , Figure 5 and Figure 6 As shown, the plate 310, the first piece 321, and the second piece 322 are arranged sequentially from bottom to top. The first reinforcing rib 320 is formed by bending the first piece 321 and the second piece 322, which helps to enhance the deformation resistance of the first reinforcing rib 320 and enhance the stability of the reinforcing plate 300 in the left and right directions. After the reinforcing plate 300 is connected to the lower shell 100 to form a lower module, it helps to reduce the deformation amplitude of the lower module under pressure, thereby reducing the pressure on the screen module 200 after the lower module is deformed under pressure. This reduces the impact of the deformation of the lower shell 100 on the screen module 200 and achieves effective support and pressure bearing for the screen module 200, ensuring the normal display of the screen module 200.

[0048] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the reinforcing plate 300 includes two second reinforcing ribs 330 connected to the left and right edges of the plate body 310 respectively. The length direction of the second reinforcing ribs 330 is arranged along the front-rear direction. The second reinforcing ribs 330 are bent upward and arranged at right angles to the plate body 310. The arrangement of the second reinforcing ribs 330 can enhance the stability of the reinforcing plate 300 in the front-rear direction, thereby improving the deformation resistance of the reinforcing plate 300. This helps to reduce or block the pressure on the screen module 200 after the lower shell 100 is deformed under pressure, and achieves effective support and pressure bearing for the screen module 200, so as to ensure the normal display of the screen module 200.

[0049] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the reinforcing plate 300 also includes an extension plate 340. The extension plate 340 and the plate body 310 are integrally formed parts, that is, the extension plate 340 and the plate body 310 are made of the same material. The extension plate 340 is connected to the side of the plate body 310 facing away from the adjacent reinforcing plate 300. The two ends of the extension plate 340 are arranged in the left and right direction. The front edge and the rear edge of the extension plate 340 are respectively connected to the upwardly bent third reinforcing rib 350.

[0050] Reference Figure 2 , Figure 4 and Figure 5 As shown, the extension plate 340 of the left-side reinforcing plate 300 is connected to the left side of the plate body 310 and extends to the left. The front and rear edges of the left-side reinforcing plate 300 are respectively connected to upward-bent third reinforcing ribs 350. The extension plate 340 of the right-side reinforcing plate 300 is connected to the right side of the plate body 310 and extends to the right. The front and rear edges of the right-side reinforcing plate 300 are respectively connected to upward-bent third reinforcing ribs 350.

[0051] Reference Figure 2 , Figure 4 and Figure 5 As shown, the reinforced screen device, through the setting of the extension plate 340 and the third reinforcing rib 350, can further enhance the ability of the reinforcing plate 300 to resist bending deformation, thereby improving the deformation resistance of the reinforcing plate 300. This helps to reduce or block the pressure on the screen module 200 after the lower shell 100 is deformed under pressure, and achieves effective support and pressure bearing for the screen module 200, so as to ensure the normal display of the screen module 200.

[0052] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the reinforcing plate 300 includes two extension plates 340. Within a reinforcing plate 300, the two extension plates 340 are arranged at a distance from each other. The two extension plates 340 are located in front of and behind the second reinforcing rib 330, respectively, and an engaging space is constructed between the two extension plates 340.

[0053] Reference Figure 2 , Figure 4 and Figure 5 As shown, the interlocking space can be used to adapt to the concave and convex shape of the lower shell 100 to enhance the compatibility between the reinforcing plate 300 and the lower shell 100. After the reinforcing plate 300 and the lower shell 100 are connected, they can jointly form a lower module, which helps to reduce the deformation amplitude of the lower module under pressure, thereby reducing the influence of the deformation of the lower shell 100 on the screen module 200, and achieving effective support and pressure bearing for the screen module 200 to ensure the normal display of the screen module 200.

[0054] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the plate 310 has a downwardly bent recess 311. The length direction of the recess 311 is the front-to-back direction, that is, the length direction of the recess 311 is arranged at a right angle to the length direction of the lower shell 100. That is, the upper surface of the plate 310 is recessed at the recess 311, and the lower surface of the plate 310 is convex at the recess 311. By setting the recess 311, the reinforcing plate 300 can effectively enhance the overall strength of the reinforcing plate 300, that is, enhance the bending deformation resistance of the reinforcing plate 300.

[0055] Reference Figure 2 , Figure 4 and Figure 5 As shown, the reinforcing plate 300 can be formed by bending to create a recess 311, a first reinforcing rib 320, a second reinforcing rib 330, and a third reinforcing rib 350. Production personnel can first form the recess 311 on the reinforcing plate 300 to enhance the overall strength of the reinforcing plate 300. Then, by bending the edge of the reinforcing plate 300, the first reinforcing rib 320, the second reinforcing rib 330, and the third reinforcing rib 350 are formed. The first reinforcing rib 320, the second reinforcing rib 330, the third reinforcing rib 350, and the extension plate 340 are integrally formed with the plate body 310, which helps to enhance the overall strength of the reinforcing plate 300, that is, to enhance the bending deformation resistance of the reinforcing plate 300.

[0056] Reference Figure 2 , Figure 5 and Figure 6 As shown, it is understood that the reinforced screen device also includes multiple threaded fasteners 400, which may be screws. The recess 311 is provided with multiple mounting holes 314, and the lower shell 100 is provided with multiple connecting posts 120 corresponding to the mounting holes 314. Each mounting hole 314 corresponds to one connecting post 120.

[0057] Reference Figure 2 , Figure 5 and Figure 6 As shown, the connecting post 120 is provided with a screw hole, the upper end of the connecting post 120 abuts against the reinforcing plate 300, the threaded fastener 400 corresponds one-to-one with the mounting hole 314, the threaded fastener 400 passes through the mounting hole 314 and is threadedly connected to the screw hole.

[0058] Reference Figure 2 , Figure 5 and Figure 6 As shown, during assembly, the production personnel can align the reinforcing plate 300 with the lower shell 100 so that the connecting post 120 and the mounting hole 314 are aligned one by one. Then, the threaded fastener 400 is inserted into the mounting hole 314 and threadedly connected to the screw hole, thereby realizing the detachable connection between the reinforcing plate 300 and the lower shell 100.

[0059] Reference Figure 2 , Figure 5 and Figure 6 As shown, it can be understood that the plate 310 is provided with multiple anti-foolproof positioning holes 313, and the lower shell 100 is provided with multiple anti-foolproof positioning posts 130. The anti-foolproof positioning posts 130 correspond one-to-one with the anti-foolproof positioning holes 313, and the anti-foolproof positioning posts 130 pass through the anti-foolproof positioning holes 313.

[0060] Reference Figure 2 , Figure 5 and Figure 6 As shown, during assembly, production personnel can align the anti-foolproof positioning post 130 with the anti-foolproof positioning hole 313 one by one, and make the anti-foolproof positioning post 130 pass through the anti-foolproof positioning hole 313 to assist in the alignment and positioning of the reinforcing plate 300 and the lower shell 100, and make the connecting post 120 and the mounting hole 314 one by one to assist in the positioning and connection of the reinforcing plate 300 and the lower shell 100, so as to improve the production efficiency of this reinforced screen equipment.

[0061] Reference Figure 2 , Figure 5 and Figure 6 As shown, specifically, one of the anti-misalignment positioning posts 130 is cylindrical, and one of the corresponding anti-misalignment positioning holes 313 is round; another anti-misalignment positioning post 130 is square, and one of the corresponding anti-misalignment positioning holes 313 is square. This reinforced screen equipment, through the arrangement of various shapes of anti-misalignment positioning holes 313 and anti-misalignment positioning posts 130, guides production personnel to assemble the corresponding anti-misalignment positioning posts 130 with the anti-misalignment positioning holes 313, thereby preventing the production personnel from assembling the reinforcing plate 300 backwards.

[0062] Reference Figure 2 , Figure 5 and Figure 6 As shown, it is understandable that the plate 310 is provided with multiple weight-reducing holes 312, which helps to reduce the weight and manufacturing cost of the reinforcing plate 300. Furthermore, the upper end of the connecting post 120 abuts against the lower end of the reinforcing plate 300, so that a gap is formed between the lower end of the reinforcing plate 300 and the bottom wall of the receiving groove 110. The weight-reducing holes 312 can be used as heat dissipation holes, allowing components located above the reinforcing plate 300 to transfer heat downwards through the heat dissipation holes, thereby improving the heat dissipation efficiency of the lower module and enhancing the durability of the reinforced screen device.

[0063] Reference Figure 2 , Figure 5 and Figure 6As shown, it can be understood that the bottom surface of the receiving groove 110 is connected to multiple intersecting partitions. The partitions help to enhance the stability of the lower module, reduce the deformation caused by pressure on the lower module, reduce the risk of damage to the screen module 200 under pressure, and ensure the normal display of the screen module 200. The lower surface of the reinforcing plate 300 and the bottom surface of the receiving groove 110 are provided with a gap, which helps to enhance the heat dissipation performance of the lower module.

[0064] Reference Figure 2 , Figure 5 and Figure 6 As shown, the lower shell 100 has multiple through holes running vertically, and the lower end of the reinforcing plate 300 is connected to multiple downward-extending mounting posts. The mounting posts are arranged in a one-to-one correspondence with the through holes, and the mounting posts have downward-facing screw holes. This reinforced screen device also includes a bracket, which is located at one end of the lower shell 100 facing away from the screen module 200.

[0065] Reference Figure 2 , Figure 5 and Figure 6 As shown, during assembly, production personnel can insert the mounting post into the through hole to assist in positioning the reinforcing plate 300 and the lower shell 100. The mounting post is inserted into the through hole, and then the screw is threaded through the bracket and connected to the screw hole of the mounting post in the through hole. That is, the reinforcing plate 300 can serve as the base for bracket connection, so that the reinforcing plate 300, the lower shell 100 and the bracket are connected as one, which helps to improve the overall strength of the lower module, improve the lower module's resistance to bending deformation, and achieve effective support for the screen module 200 to ensure the normal display of the screen module 200.
