Abstract

The invention provides a front frame structure and screen equipment. The front frame structure comprises a front frame, an optical touch module and a protective film piece. The front frame is detachably arranged on the display screen and is provided with a first outer retaining wall and a first inner retaining wall in a protruding mode. The first side frame portion of the front frame can be pivoted away from or close to the display screen. The optical touch module is arranged in the front frame. The protective film piece is arranged between the front frame and the display screen and comprises a protective film and a film frame annularly connected with the protective film. The second side connecting frame part of the film frame is detachably connected to the first side connecting frame part of the front frame, and a second outer retaining wall and a second inner retaining wall protrude out of the film frame. When the film frame slides into the front frame and the first side frame part pivots towards the display screen, the first outer retaining wall and the first inner retaining wall interfere and slide along the lead angle structures of the second outer retaining wall and the second inner retaining wall respectively until the first outer retaining wall enters the space between the second outer retaining wall and the second inner retaining wall, so that the film frame slides outwards to tension the protective film.

Description

TECHNICAL FIELD

[0001] The present application relates to a detachable front frame structure and a screen device thereof, in particular to a detachable front frame structure and a screen device thereof using a slide interference fit between a film frame and a front frame to enable a protective film accommodated in the film frame to slide into or out of the front frame. BACKGROUND

[0002] Generally, large-size display screen devices on the market are formed by fixed-size spliced screens spliced with each other, and a pivot is arranged between the spliced screens to pivotally connect adjacent spliced screens to each other to provide a screen folding function. On the other hand, in order to expand the functionality of the large-size display screen device, an optical touch module is usually arranged in the front frame, and a protective film is attached to the display surface of the large-size display screen device to eliminate the splicing gap between the spliced screens to allow the user to perform optical touch operation on the protective film, thereby improving the touch feeling.

[0003] However, in the above design, if the spliced screen shows abnormality and needs to be repaired or replaced, the user must completely disassemble the front frame and remove the protective film before repairing or replacing the abnormal screen, which will result in a time-consuming and laborious screen repair and replacement process of the large-size display screen device. In addition, if the protective film is not tightly and flatly attached to the display surface and has unevenness, it will also result in poor touch feeling.

[0004] Therefore, it is necessary to design a new front frame structure and a screen device thereof to overcome the above-mentioned defects. SUMMARY

[0005] The present application aims to provide a detachable front frame structure and a screen device thereof using a slide interference fit between a film frame and a front frame to enable a protective film accommodated in the film frame to slide into or out of the front frame to solve the above-mentioned problems.

[0006] To achieve the above-mentioned purpose, the present application provides a front frame structure and a screen device thereof, the front frame structure comprising:

[0007] a front frame having a first top frame portion, a first side frame portion, a first bottom frame portion and a first side joint frame portion connected in sequence and detachably arranged on a display screen; the first top frame portion, the first side frame portion and the first bottom frame portion all protrude towards the display screen to form a first outer barrier wall and a first inner barrier wall, the first top frame portion and the first bottom frame portion each have at least one pivot, and the first side frame portion is pivoted away from or close to the display screen through the pivot; and

[0008] a protective film member arranged between the front frame and the display screen, the protective film member comprising:

[0009] Protective film; and

[0010] The membrane frame has a second top frame portion, a second side frame portion, a second bottom frame portion, and a second side connecting frame portion to sequentially circumferentially connect the protective film; the second top frame portion, the second side frame portion, and the second bottom frame portion all protrude toward the front frame to form a second outer baffle and a second inner baffle to jointly define a limiting groove space, and the second outer baffle and the second inner baffle are respectively formed with chamfer structures;

[0011] When the first side frame pivots away from the display screen, the first outer wall of the first top frame and the first outer wall of the first bottom frame slide in cooperation with the limiting groove space, so that the film frame slides into the front frame or is pulled out from the front frame.

[0012] When the film frame slides into the front frame and the first side frame pivots toward the display screen, the first outer baffle and the first inner baffle respectively interfere with and slide with the corresponding chamfer structure, so that the first outer baffle enters the limiting groove space, causing the film frame to slide outward and tighten the protective film.

[0013] Preferably, it also includes: an optical touch module disposed in the first top frame, the first side frame, the first bottom frame and the first side connecting frame, for establishing a touch sensing area on the display screen.

[0014] Preferably, the second top frame portion and the second bottom frame portion each have a clearance groove at the position corresponding to the pivot.

[0015] Preferably, the protective film is housed in the film frame by heat fusion bonding.

[0016] Preferably, the second side frame portion is detachably connected to the first side frame portion.

[0017] Preferably, it further includes: at least one clamping piece connected to at least one of the first top frame portion and the first bottom frame portion to detachably clamp the display screen to the front frame.

[0018] Preferably, the thickness of the second outer retaining wall is different from the thickness of the second inner retaining wall.

[0019] Preferably, the thickness of the second outer retaining wall is greater than the thickness of the second inner retaining wall.

[0020] Preferably, each of the first outer retaining walls and each of the first inner retaining walls interferes with the corresponding chamfer structure, such that the distance by which the membrane frame slides outward to tighten the protective membrane is between 0.2 mm and 0.5 mm.

[0021] Preferably, the horizontal width of the chamfer structure is between 0.5mm and 0.8mm, and the vertical height of the chamfer structure is between 1mm and 1.6mm.

[0022] Preferably, a screen device includes:

[0023] Display screen; and

[0024] The aforementioned front frame structure is used to accommodate the display screen.

[0025] Preferably, the display screen is composed of multiple spliced ​​screens.

[0026] Compared to previous technologies that directly adhered the entire protective film to large-size display screens, this invention utilizes a sliding interference mechanism between the film frame and the front frame to allow the protective film housed within the film frame to detachably slide into or out of the front frame. This means that if a display malfunction occurs and repair or replacement is needed, the detachable front frame structure allows the user to easily remove the protective film by simply pulling the front frame pivot. Therefore, this invention effectively solves the time-consuming and labor-intensive screen repair and replacement process for large-size display screens mentioned in previous technologies (because the front frame must be completely removed and the protective film peeled off before subsequent processes can proceed). It also avoids unevenness caused by the protective film not being taut and flat against the display surface, thus greatly improving the touch feel of large-size display screens and the ease of operation during screen repair and replacement.

[0034] To provide a further understanding of the purpose, structure, features, and functions of the present invention, detailed descriptions are provided below with reference to specific embodiments.

[0035] Certain terms are used in the specification and claims to refer to specific elements. Those skilled in the art will understand that manufacturers may use different names to refer to the same element. This specification and claims do not distinguish elements by differences in name, but rather by differences in function. The term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to." In particular, the structural design and connection relationships of the various elements in the drawings (such as the structural presentation and scale of the optical touch module / display screen) are for illustrative purposes only and do not represent the actual implementation of the invention.

[0036] Please see Figure 1 as well as Figure 2 , Figure 1 This is a perspective view of a screen device 10 according to an embodiment of the present invention. Figure 2 for Figure 1 An exploded view of the screen device 10, by Figure 1 as well as Figure 2 It is understood that the screen device 10 includes a display screen 12 and a detachable front frame structure 14, wherein the display screen 12 can preferably be composed of multiple splicing screens (such as... Figure 2 The twenty-five splicing screens 13 shown are not limited to this number, and the number of screens spliced ​​depends on the actual application needs of the screen device 10, thereby constructing a large-size display screen device composed of multiple screens spliced ​​side by side. As for the relevant description of the screen splicing structure design for the display screen 12, it is common in the prior art and will not be repeated here.

[0037] Please see Figure 1 , Figure 2 , Figure 3 ,as well as Figure 4 , Figure 3 for Figure 2 A magnified view of part of the front frame 16. Figure 4 for Figure 2 A partially enlarged schematic diagram of membrane frame 42. (See attached diagram.) Figures 1 to 4As shown, the detachable front frame structure 14 accommodates the display screen 12 as a bezel structure for the display screen 12. The detachable front frame structure 14 includes a front frame 16, an optical touch module 18, and a protective film 20. The front frame 16 is detachably mounted on the display screen 12 and has a first top frame portion 22, a first side frame portion 24, a first bottom frame portion 26, and a first side connecting frame portion 28 connected in sequence. The optical touch module 18 is preferably an infrared touch module (but is not limited to this; it can also use other types of optical touch light sources, such as laser, ultraviolet, or visible light) and is disposed within the first top frame portion 22, the first side frame portion 24, the first bottom frame portion 26, and the first side connecting frame portion 28 to establish a touch sensing area 19 on the display screen 12 (e.g., Figure 1 (As shown in the dotted area), so that subsequent users can perform related optical touch operations such as moving the cursor on the display screen 12. As for the description of the component configuration (such as reflector, light source, circuit board, etc.) of the optical touch module 18, it is common in the prior art and will not be repeated here.

[0038] More specifically, in this embodiment, the detachable front frame structure 14 preferably adopts a clamping detachable design (but is not limited to this; it can also adopt other detachable designs, such as structural snap-fit, etc.), for example, by Figure 1 as well as Figure 2 It is understood that the front frame 16 may further have at least one clamping piece 30 connected to at least one of the first top frame portion 22 and the first bottom frame portion 26 (in Figure 1 The image shows two clamping pieces 30 detachably connected (e.g., by screw fastening) to the first top frame 22, but this is not a limitation; a top / bottom frame dual-sided clamping design can also be used. This allows the display screen 12 to be detachably clamped to the front frame 16 by the front and rear clamping of the first top frame 22 and the clamping pieces 30. Regarding the clamping structure design for the clamping pieces 30 (e.g....), Figure 2 The description of the bending clamping piece design shown (but not limited to this) is common in prior art and will not be repeated here. Furthermore, by Figure 2 as well as Figure 3 It can be seen that the first top frame 22, the first side frame 24, and the first bottom frame 26 can each protrude into the display screen 12 to form a first outer barrier 32 and a first inner barrier 34 (in Figure 3 The first bottom frame section 26 is not shown in the image; its retaining wall design can be found in the following description. Figure 3 (and so on), and the first top frame portion 22 and the first bottom frame portion 26 may each have at least one pivot 36 (at Figure 2In the middle, the first top frame portion 22 and the first bottom frame portion 26 each have two pivots 36 (but not limited thereto), so that the first side frame portion 24 can pivot via the pivots 36 to move away from or towards the display screen 12, so that the user can subsequently perform the disassembly and assembly operations of the detachable front frame structure 14.

[0039] Regarding the design of the protective film 20, such as Figure 2 as well as Figure 4 As shown, the protective film 20 is disposed between the front frame 16 and the display screen 12 and includes a protective film 40 and a film frame 42. The film frame 42 has a second top frame portion 44, a second side frame portion 46, a second bottom frame portion 48, and a second side connecting frame portion 50 to sequentially circumferentially connect the protective film 40. The protective film 40 is preferably a PET (Polyethylene Terephthalate) film, but is not limited thereto. Other types of protective film materials such as TPU (Thermoplastic Polyurethanes) can also be used. The protective film 40 is preferably housed in the film frame 42 by heat fusion bonding (but is not limited thereto. Other bonding methods such as structural clamping or adhesive bonding can also be used).

[0040] Furthermore, the second side frame portion 50 is detachably connected to the first side frame portion 28 (preferably by screw fastening, but not limited to this; other common connection methods, such as interlocking structures, can also be used). The second top frame portion 44, the second side frame portion 46, and the second bottom frame portion 48 can each protrude towards the front frame 16 to form a second outer retaining wall 52 and a second inner retaining wall 54 to jointly define the limiting groove space S (in... Figure 4 The second bottom frame section 48 is not shown in the image; its retaining wall design can be found in the following description. Figure 4 (Similarly), and the second outer retaining wall 52 and the second inner retaining wall 54 can each be formed with a chamfered corner structure 56.

[0041] More specifically, in this embodiment, the membrane frame 42 can preferably be designed with different retaining wall thicknesses, for example, such as Figure 4 As shown, the thickness of the second outer retaining wall 52 can preferably be greater than the thickness of the second inner retaining wall 54 (but is not limited to this; it can also be designed so that the thickness of the second outer retaining wall 52 is less than the thickness of the second inner retaining wall 54). This is to improve the frame strength of the membrane frame 42 by using a relatively thicker outer retaining wall, and to increase the structural elasticity of the second inner retaining wall 54 by using a relatively thinner inner retaining wall to avoid interference and jamming problems in the retaining wall structure. It should be noted that, as Figure 2 as well as Figure 4As shown, the second top frame portion 44 and the second bottom frame portion 48 can each have a relief groove 38 at the position corresponding to the pivot 36, thereby providing the structural space required for the first side frame portion 24 to pivot, thereby avoiding the problem of the display screen 12 being squeezed by the front frame 16 during the pivot of the first side frame portion 24 via the pivot 36, which would cause deformation.

[0042] This section provides a detailed description of the screen protector removal and installation process for screen device 10. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 5 , Figure 6 ,as well as Figure 7 , Figure 5 for Figure 1 A partial cross-sectional view of the screen device 10 along section line AA. Figure 6 for Figure 5 A partial cross-sectional view of the first side frame 24 pivoting away from the display screen 12 via pivot 36, as shown in the figure. Figure 1 A partial cross-sectional view of the screen device 10 along section line BB. Figure 1 , Figure 2 , Figure 5 , Figure 6 ,as well as Figure 7 It is understood that when a user wants to perform screen replacement / repair or other related operations on the screen device 10, the user only needs to disconnect the connection between the first side frame portion 28 of the front frame 16 and the second side frame portion 50 of the membrane frame 42 (for example, by using a screwdriver to loosen the screws), and then pivot the first side frame portion 24 upward from the engaged position as shown in Figure 5 (for example, pivot it to the position shown in Figure 5). Figure 6 (The unfolded position shown is not limited to this position). At this time, since the first outer baffle 32 and the first inner baffle 34 of the first side frame portion 24 of the front frame 16 have been separated from the second outer baffle 52 and the second inner baffle 54 of the second side frame portion 46 of the membrane frame 42, the structural engagement limit between the first side frame portion 24 and the second side frame portion 46 is released. Therefore, the structural guidance (such as the first outer baffle 32 and the first inner baffle 34 of the front frame 16 interlocking with the second outer baffle 52 and the second inner baffle 54 of the membrane frame 42) is achieved. Figure 7 As shown, this means that the first outer retaining wall 32 of the first top frame portion 22 and the first outer retaining wall 32 of the first bottom frame portion 26 can be slidably engaged with the limiting groove space S, so that the user can... Figure 6 The membrane frame 42, together with the protective film 40, is completely removed from the front frame 16 so that the user can directly perform subsequent replacement / repair of the splicing screen 13 and other related operations on the display screen 12 that is no longer covered by the protective film 40.

[0043] On the other hand, after completing the screen replacement / repair and other related operations for the screen device 10, the user can align the film frame 42 with the front frame 16 so that the second outer wall 52 and the second inner wall 54 of the film frame 42 are respectively interlocked with the first outer wall 32 and the first inner wall 34 of the front frame 16 (e.g., Figure 7 As shown, this means that the first outer retaining wall 32 of the first top frame portion 22 and the first outer retaining wall 32 of the first bottom frame portion 26 can slide within the limiting groove space S respectively, until the film frame 42 slides into the front frame 16 so that the protective film 40 covers the display screen 12 (as shown). Figure 6 (As shown); Next, after detachably connecting the first side frame portion 28 of the front frame 16 to the second side frame portion 50 of the membrane frame 42 (e.g., by screw fastening), the user only needs to remove the first side frame portion 24 from the membrane frame 42. Figure 6 The unfolded position shown pivots downwards toward the display screen 12 as follows. Figure 5 The engagement position is shown, thus completing the film frame assembly operation of the screen device 10. During this process, as the first side frame portion 24 pivots downwards, the first outer retaining wall 32 and the first inner retaining wall 34 of the first side frame portion 24 will first abut against... Figure 6 The chamfered corner structure 56 shown then interferes with the second outer retaining wall 52 and the second inner retaining wall 54 along the chamfered corner structure 56, thereby guiding the first outer retaining wall 32 into the limiting groove space S to produce a limiting engagement effect. At this time, since the first outer retaining wall 32 and the first inner retaining wall 34 still interfere with the second outer retaining wall 52 and the second inner retaining wall 54 respectively, the first side frame portion 24 can push the second side frame portion 46 of the membrane frame 42 to slide outwards. In addition, the top frame retaining walls between the first top frame portion 22 and the second top frame portion 44 are staggered and engaged (as shown). Figure 7 As shown), the bottom frame retaining walls between the first bottom frame portion 26 and the second bottom frame portion 48 are interlocked (refer to...). Figure 7 (Similarly), and the side frame connection between the first side frame portion 28 and the second side frame portion 50, so that the protective film 40 can be stretched taut on all four sides of the film frame 42 through the second top frame portion 44, the second side frame portion 46, the second bottom frame portion 48 and the second side frame portion 50, thereby ensuring that the protective film 40 housed in the film frame 42 can be flatly and tightly covered on the display screen 12 and eliminate the splicing gaps between the splicing screens 13, thereby greatly improving the touch feel of the user when performing optical touch operation on the display screen 12.

[0044] It is worth mentioning that, as mentioned above, the interference between the first outer retaining wall 32 and the first inner retaining wall 34 and their corresponding chamfered structures 56 allows the distance by which the membrane frame 42 slides outward relatively to be preferably between 0.2mm and 0.5mm, thereby effectively improving the tension and flatness of the protective film 40. More specifically, in practical experience, such as...Figure 4 The horizontal width W of the chamfer structure 56 shown can preferably be between 0.5mm and 0.8mm, and the vertical height H of the chamfer structure 56 can preferably be between 1mm and 1.6mm. However, the chamfer size design can vary according to the actual application requirements of the screen device 10 and is not limited to the above values.

[0045] In summary, compared to previous designs that directly adhered the entire protective film to large-size display screens, this invention utilizes a sliding interference mechanism between the film frame and the front frame to allow the protective film housed within the film frame to detachably slide into or out of the front frame. This means that if a display malfunction occurs and repair or replacement is required, the detachable front frame structure provided by this invention allows the user to easily remove the protective film by simply pulling the front frame pivot. Therefore, this invention not only effectively solves the time-consuming and labor-intensive screen repair and replacement process for large-size display screens mentioned in previous technologies (because the front frame must be completely removed and the protective film peeled off before subsequent processes can proceed), but also reliably avoids unevenness caused by the protective film not being taut and flat against the display surface. This significantly improves the touch feel of large-size display screens and the ease of operation during screen repair and replacement.

[0046] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
