Abstract
Description
A display device, frame assembly and middle frame structure Technical Field
[0001] The present application relates to the technical field of electronic devices, and in particular to a display device, a frame assembly, and a middle frame structure. Background Art
[0002] Current display devices (such as interactive conference tablets) generally consist of three main components: a back panel module, a frame assembly, and a cover panel assembly. The frame assembly includes the frame body, a glass bracket, and a mid-frame. The glass bracket is fixed to one side of the frame body to support the cover panel assembly, while the mid-frame is fixed to the other side of the frame body to provide a mounting position for the back panel module.
[0003] However, due to the relatively large size of the backplane module and cover panel assembly, the assembly process between the backplane module and the cover panel assembly is quite difficult. The difficulty in aligning the components during assembly affects the assembly accuracy between the backplane module and the cover panel assembly, which also reduces the assembly efficiency of the display device and makes automated production difficult. Furthermore, the product's quality control is low, which ultimately affects the user experience.
[0004] Summary of the Invention
[0005] The purpose of this application is to provide a display device, a frame assembly and a middle frame to solve the problems of assembly efficiency and precision between the back plate and the cover plate assembly.
[0006] To solve the above technical problems, this application adopts the following technical solutions:
[0007] In a first aspect, a display device is provided, comprising:
[0008] A frame assembly, the front side of which is provided with a glass bracket for supporting and fixing the cover assembly, and the rear side of the frame assembly is formed with a guide slope, the guide slope is located on the inner side of the frame assembly and is inclined outward in the direction from the front side to the rear side of the frame assembly;
[0009] The middle frame is fixedly mounted on the back plate, and an assembly slope adapted to the guide slope is formed on the front side of the middle frame. The frame assembly is guided to the assembly slope through the guide slope so that the middle frame is assembled to the inner side of the frame assembly and fixedly connected to the frame assembly.
[0010] In a second aspect, a frame assembly is provided for use with an interactive tablet, wherein a glass bracket for supporting and fixing a cover assembly is provided on the front side of the frame assembly, and a guide slope is formed on the rear side of the frame assembly. The guide slope is located on the inner side of the frame assembly and is tilted outward in the direction from the front side to the rear side of the frame assembly. The guide slope is used to guide the assembly slope of the middle frame and cooperate with the middle frame limiter through the assembly slope of the middle frame.
[0011] In a third aspect, a middle frame structure is provided, which is applied to an interactive tablet. The middle frame can be installed on a back panel. An assembly bevel is formed on the front side of the middle frame. The assembly bevel is located on the outside of the middle frame and is inclined inward from the front to the back of the middle frame. The assembly bevel is used to guide the guide bevel of the frame assembly, and is limited by the guide bevel of the frame assembly.
[0012] The beneficial effects of the present application are as follows: the display device forms a guiding slope on the rear side of the frame assembly, and the guiding slope is located on the inner side of the frame assembly and is tilted outward from the front to the rear side of the frame assembly, so that the opening enclosed by the rear side of the frame assembly gradually expands from the front to the rear, thereby facilitating the assembly of the back plate with the middle frame on the frame assembly. The middle frame can relatively easily enter the inner side of the frame assembly from the opening and complete its subsequent assembly on the frame assembly, thereby reducing the assembly difficulty of the display device and effectively improving the product assembly efficiency;
[0013] The frame assembly and the middle frame are guided and continuously limited after assembly through the cooperation of the guiding bevel and the assembly bevel, so that the middle frame can be gradually guided to the correct assembly position during the process of wedging into the inner side of the frame assembly, and finally the middle frame and the back panel installed with the middle frame are stably constrained in the correct assembly position, thereby improving the matching accuracy between the back panel module and the cover assembly, meeting the assembly requirements of the product while also improving the user experience.

[0028] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.
[0029] In the description of this application, unless otherwise specified or limited, the terms "connected" and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0030] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
[0031] Current display devices (such as interactive conference tablets) generally consist of three main components: a back panel module, a frame assembly, and a cover panel assembly. The frame assembly includes the frame body, a glass bracket, and a mid-frame. The glass bracket is fixed to one side of the frame body to support the cover panel assembly, while the mid-frame is fixed to the other side of the frame body to provide a mounting position for the back panel module.
[0032] In the relevant technical solutions, on the one hand, due to a series of factors such as the relatively large size of the back panel module and the cover panel assembly, the assembly process between the back panel module and the cover panel assembly is difficult, and it is difficult to align the components during the assembly process. Even after the alignment of the components is completed, the back panel module, the frame assembly and the cover panel assembly are fixed by multiple fixings such as pressure blocks and screws, resulting in a decrease in the assembly accuracy between the back panel module and the cover panel assembly, and also a decrease in the assembly efficiency of the display device, making it difficult to achieve automated production. In addition, the quality control of the product is low, which ultimately affects the user experience. On the other hand, fixings such as pressure blocks and screws need to be designed with a certain amount of space for movement. As the product ages, fixing components such as clips and screws will become increasingly loose due to factors such as the space for movement, vibration during transportation, and gravity, resulting in a decline in product quality and affecting the product's reputation.
[0033] To this end, the inventors reduced the use of fixings such as pressing blocks and screws in the process of implementing this technical solution, which can improve assembly efficiency, but inevitably reduces assembly accuracy. To achieve both high assembly efficiency and high assembly accuracy, this embodiment provides a display device that improves the assembly relationship between the back panel 50 and the cover assembly 40, specifically optimizing the matching structure between the frame assembly 10 and the middle frame 30, thereby resolving a series of problems mentioned in the background art, such as the relatively low assembly accuracy and efficiency of the product resulting from the relatively high difficulty in assembling the cover assembly 40 and the back panel 50.
[0034] It should be noted that the display device of this embodiment is primarily used in commercial scenarios. Examples include LCD advertising machines, conference display screens, LCD splicing screens, touch-screen all-in-one machines, outdoor advertising machines, digital smart water signs, self-service terminals, and customized commercial displays. Like general display devices, a display device can be used to output image information and may also be referred to as a display, or more commonly, a display screen, or a screen. Specifically, the display device may be a direct-lit or edge-lit LCD display device with a backlight.
[0035] As a detailed description of the display device, when used as an interactive tablet, the display device can also operate the content displayed on the display screen and realize human-computer interaction through capacitive touch technology and electromagnetic induction technology. It integrates one or more functions such as a projector, whiteboard, screen, audio, television, and video conferencing terminal. In actual application, the hardware part of the interactive tablet is composed of parts such as a touch module, a display module 42, and an intelligent processing system. They are combined together by integral structural parts and are also supported by a dedicated software system. The display module 42 and the touch module cooperate to realize display and touch functions. The user can touch the display screen with a finger or a stylus. The intelligent processing system generates handwriting based on the touch operation input by the user and displays it on the display screen, or generates control operations based on the touch operation input by the user to process the display content on the display screen.
[0036] As shown in Figures 1 to 12, in order to facilitate a more comprehensive understanding of the present solution, for the display device and the components therein, the side close to the center direction of the cover assembly 40 is the inner side of the component, that is, the "inner" direction indicated by the arrows in the accompanying drawings, and the side away from the center direction of the cover assembly 40 is the outer side of the component, that is, the "outer" direction indicated by the arrows in the accompanying drawings; and the side of the display device used to provide the image display function, that is, the side of the cover assembly 40 providing image display when the display device is in use by the user, is the front side of the component, that is, the "front" direction indicated by the arrows in the accompanying drawings, and the side of the interactive flat panel used to set the back panel 50 is regarded as the rear side of the component, that is, the "rear" direction indicated by the arrows in the accompanying drawings.
[0037] Please refer to Figures 1-2. The display device includes a frame assembly 10. The frame assembly 10 serves as the supporting base of the display device. In the application of the display device and related products, it can be adaptively adjusted according to the corresponding product structure. For example, the frame assembly 10 can be a frame structure formed by splicing and enclosing multiple frame members, or it can be a frame structure as a single piece processed by an integrated molding process. In addition, the frame members in the frame structure can be selectively processed by extrusion molding or roll molding according to the relevant needs of users, products, etc., and its structure can be a profile frame with a cavity, or a sheet metal frame with a plate-like structure.
[0038] In this embodiment, the frame assembly 10 is divided into four sections, and the four sections of the frame assembly 10 are connected in sequence and enclosed to define the installation area. Specifically, any two adjacent frame assemblies 10 are set at an angle, and the assembly angle between the two can be adjusted according to the product structure requirements of the interactive tablet.
[0039] Please continue to refer to Figures 3-5 and 9-10. A glass bracket 20 for supporting and fixing the cover assembly 40 is provided on the front side of the frame assembly 10. It can be understood that the frame assembly 10 and the glass bracket 20 can be formed by an integrated molding process, such as the two are integrally molded by extrusion, milling and other processes, or the frame assembly 10 and the glass bracket 20 can also be formed by separate processes and then assembled by welding, splicing and other assembly processes.
[0040] In this embodiment, the frame assembly 10 includes a first frame 17 and a second frame 18, wherein the first frame 17 and the second frame 18 are respectively two sections in the embodiment of the frame structure formed by the four-section frame assembly 10, and the first frame 17 and the second frame 18 are alternately connected, as shown in Figures 1-5 and Figures 9-10. In this example, the first frame 17 is respectively arranged on the left and right sides of the display device, and the second frame 18 is respectively arranged on the upper and lower sides of the display device, and there is a certain difference in the specific structure of the first frame 17 and the second frame 18. In the preparation, the second frame 18 serving as the upper and lower frames needs to bear a greater supporting weight. A bite protrusion 181 is convexly provided on the inner side of the second frame 18, and the glass bracket 20 is provided with a bite groove 25 adapted to the structure of the bite protrusion 181, and is assembled on the second frame 18 by snap-fitting. The first frame 17 can be set to be integrally formed with the glass bracket 20 as shown in the figure, or the glass bracket 20 can be set to extend in the front and rear directions and installed on the inner side of the first frame 17, so that the width of the first frame 17 is narrower than the width of the second frame 18.
[0041] Continuing from Figures 3-5 and 11-12, it can be seen that the rear side of the frame assembly 10 is used to be installed with the middle frame 30. In this example, a guide slope 11 is formed on the rear side of the frame assembly 10. The guide slope 11 is located on the inner side of the frame assembly 10 and is tilted outward in the direction from the front to the rear of the frame assembly 10, so that the opening enclosed by the rear side of the frame assembly 10 gradually expands from the front to the rear, thereby facilitating the assembly of the back plate 50 with the middle frame 30 on the frame assembly 10, and the middle frame 30 can relatively easily enter from the opening to The inner side of the frame assembly 10 and completes its subsequent assembly on the frame assembly 10, thereby reducing the assembly difficulty of the display device and effectively improving the product assembly efficiency. Moreover, as the middle frame 30 gradually moves from back to front, the opening gradually narrows to gradually guide the middle frame 30 to the most accurate assembly position, and finally achieve fixed installation with the frame assembly 10, thereby saving the steps of manual step-by-step alignment during the assembly process, while improving the product assembly efficiency, also improving the assembly accuracy between the cover assembly 40 and the back plate 50.
[0042] Of course, in this embodiment, it is not necessary to form the guide bevel 11 on each frame assembly 10. For example, as shown in Figures 1 to 10, the guide bevel 11 is only formed on the rear side of the first frame 17 serving as the left and right frames of the display device, while the rear side of the second frame 18 serving as the upper and lower frames of the display device is only provided with a plate-like structure. That is to say, during the assembly process of the frame assembly 10 and the middle frame 30, the middle frame 30 is connected to the back plate 50 fixedly matched with the middle frame 30 and is gradually guided to the correct assembly position only under the action of the first frame 17. After being guided to the correct assembly position, the back plate 50 is fixedly matched with the middle frame 30. Each middle frame 30 can be installed and matched with the first frame 17 and the second frame 18 respectively. In this embodiment, the assembly process of the back panel 50 only requires the first frame 17 to position and guide its left and right position on the display device, so as to improve the assembly efficiency between the back panel 50 and the cover assembly 40 and reduce the difficulty of assembling the two. Under the guidance of the guide bevel 11, the correct alignment and matching relationship is finally formed between each frame assembly 10 and the middle frame 30. While achieving the same technical effect as above, reducing the setting of the guide bevel 11 also effectively reduces the processing difficulty of the frame assembly 10.
[0043] Please continue to refer to Figures 3 to 5. The middle frame 30 included in the display device is fixedly installed on the back panel 50. That is to say, during the assembly process of the interactive flat panel, the frame assembly 10 supports the cover assembly 40 through the glass bracket 20. After the middle frame 30 is installed on the back panel 50, the back panel 50 can drive the middle frame 30 to be embedded in the installation area enclosed by the frame assembly 10, and allow the back panel 50 to cover the frame assembly 10, thereby completing the assembly of the back panel 50 on the frame assembly 10.
[0044] Corresponding to the above embodiment, an assembly bevel 31 adapted to the guide bevel 11 is formed on the front side of the middle frame 30, that is, the inclination direction and inclination angle of the assembly bevel 31 are consistent with the guide bevel 11. During the assembly process of the middle frame 30 and the frame assembly 10, the assembly bevel 31 is located on the inner side of the guide bevel 11, and as the middle frame 30 moves from back to front, each middle frame 30 is wedged into the installation area, and finally the assembly bevel 31 and the guide bevel 11 are wedged against each other, so that the assembly position of the middle frame 30 and the back plate 50 reaches the position preset by the frame assembly 10. By ensuring the assembly stability between the middle frame 30 and the frame assembly 10 and the guidance of the middle frame 30, the assembly accuracy between the back plate 50 and the cover plate assembly 40 is improved. After the frame assembly 10 is guided to the assembly slope 31 through the guide slope 11 so that the middle frame 30 is assembled to the inner side of the frame assembly 10, the frame assembly 10 and the middle frame 30 can be further fixedly connected to complete the installation of the back panel 50 on the display device.
[0045] According to the above principle, in other embodiments, in addition to being formed on the inner side of the frame assembly 10, the guide bevel 11 can also be formed on the outer side of the frame assembly 10. When the guide bevel 11 is located on the outer side of the frame assembly 10, the assembly bevel 31 should be set at a position located on the inner side of the middle frame 30 to ensure that during the assembly process of the middle frame 30 and the frame assembly 10, the assembly bevel 31 and the guide bevel 11 remain in a relative position, so that the guide bevel 11 can guide and limit the assembly bevel 31.
[0046] Of course, if the guide bevel 11 is located on the outside of the frame assembly 10 and the assembly bevel 31 is located on the inside of the middle frame 30, when the display device is assembled, the middle frame 30 will be located on the outside of the frame assembly 10, and the frame assembly 10 will not be able to completely block the middle frame 30, which will affect the overall visual effect of the display device to a certain extent. Therefore, this embodiment can adopt an embodiment in which the guide bevel 11 is formed on the inside of the frame assembly 10 and the assembly bevel 31 is formed on the outside of the middle frame 30.
[0047] By implementing the above-mentioned technical solution, the frame assembly 10 and the middle frame 30 are guided to assemble and continuously limited after being assembled through the cooperation of the guiding bevel 11 and the assembly bevel 31, so that the middle frame 30 can be gradually guided to the correct assembly position during the process of being wedged into the inner side of the frame assembly 10, and finally the middle frame 30 and the back panel 50 installed with the middle frame 30 are stably constrained in the correct assembly position, thereby improving the matching accuracy between the back panel 50 module and the cover assembly 40, meeting the assembly requirements of the product while also improving the user experience.
[0048] In addition, according to the above-mentioned principles of the guide bevel 11 and the assembly bevel 31, in the embodiment where the guide bevel 11 is located on the outside of the frame assembly 10 and the assembly bevel 31 is located on the inside of the middle frame 30, the guide bevel 11 can also be set to be inclined inward in the direction from the front to the rear of the frame assembly 10 to ensure that the frame assembly 10 can be wedged into the inner side of the middle frame 30 through the guide bevel 11 to complete the guided assembly between the two.
[0049] Please continue to refer to Figures 3 to 5 and Figures 11 to 12, and continue to take the above-mentioned guide slope 11 as an example, which is formed only on the inner side of the frame assembly 10 serving as the first frame 17. On the basis that the frame assembly 10 constrains the assembly position of the middle frame 30 and the back plate 50 in the inner and outer directions through the guide slope 11, in order to constrain the assembly position of the middle frame 30 and the back plate 50 in the front and rear directions, a limiting portion 12 is convexly provided on the inner side of the frame assembly 10 serving as the first frame 17. The limiting portion 12 is located at Between the guide bevel 11 and the glass bracket 20, that is, on the projection of the frame assembly 10 in the front and rear directions, the projection of the limiting portion 12 is located on the inner side of the projection of the guide bevel 11. The protruding structure of the limiting portion 12 enables the limiting portion 12 to be located on the frame assembly 10 to form a boss structure, so that when the assembly bevel 31 slides along the direction of the guide bevel 11 to a position close to the limiting portion 12, the limiting portion 12 can press against the middle frame 30 through its rear side to limit the middle frame 30 from continuing to move forward.
[0050] Corresponding to the structure of the limiting portion 12, a limiting step 32 is formed on the outer side of the middle frame 30 and is located in front of the assembly inclined surface 31. The limiting step 32 structure is adapted to the structure of the limiting portion 12 and is recessed on the outer side of the middle frame 30. That is, in the projection of the middle frame 30 in the front-to-back direction, the projection of the limiting step 32 is located on the inner side of the projection of the assembly inclined surface 31. During the assembly process of the middle frame 30 and the frame assembly 10, there is no mutual interference between the limiting step 32 and the assembly inclined surface 31. As the middle frame 30 moves from back to front, the guide inclined surface 11 and the assembly inclined surface 31 gradually move relative to each other to a state of abutment. After the middle frame 30 moves to the correct assembly position, the middle frame 30 abuts against the rear side of the limiting portion 12 through the front side of the limiting step 32 to limit the movement of the middle frame 30 to the front, thereby also constraining the assembly position of the back panel 50 on the display device, thereby improving the assembly accuracy of the back panel 50 and the cover assembly 40.
[0051] Please continue to refer to Figures 3-5 and 11-12. According to the above embodiment, in order to improve the matching stability between the middle frame 30 and the frame assembly 10, a first positioning surface 121 is further formed on the inner side of the limiting portion 12, and correspondingly, the limiting step 32 is located on the step surface outside the middle frame 30 and is formed with a second positioning surface 321 that is aligned with the first positioning surface 121. According to the above embodiment, in the front and rear directions of the frame assembly 10 and the middle frame 30, the first positioning surface 121 is located on the inner side of the guide inclined surface 11, the second positioning surface 321 is located on the inner side of the assembly inclined surface 31, and the first positioning surface 121 is located on the inner side of the guide inclined surface 11, and ... The positioning surface 121 and the second positioning surface 321 extend along the front-to-back direction of the display device. That is to say, during the assembly process of the middle frame 30 and the frame assembly 10, there will be no mutual interference between the first positioning surface 121 and the second positioning surface 321, which will affect the assembly position of the middle frame 30 and the frame assembly 10 in the inside-outside direction. When the middle frame 30 is assembled on the inner side of the frame assembly 10, the first positioning surface and the second positioning surface 321 are arranged relative to each other, so that the two can only achieve the effect of improving the stability of the middle frame 30 in the correct assembly position, thereby improving the assembly stability between the back panel 50 and the cover assembly 40.
[0052] It should be noted that the implementation method of implementing the limiting constraint between the above-mentioned frame assembly 10 and the middle frame 30 through the limiting part 12 and the limiting step 32 can be set only between one of the first frames 17 and the middle frame 30, and the relative position of the other first frame 17 and the middle frame 30 in the front-to-back direction is determined by limiting the mutual constraint of one of the first frames 17 and the middle frame 30 in the front-to-back direction. The principle is that, on the basis of the constraint and limitation of one of the first frames 17 and the middle frame 30 by the limiting part 12 and the limiting step 32, the relative assembly position of the other first frame 17 and the middle frame 30 in the front-to-back direction will be determined by the mutual wedging of the guide bevel 11 and the assembly bevel 31 during the assembly process, thereby eliminating the process steps of processing the limiting part 12 and the limiting step 32 between one of the first frames 17 and the middle frame 30, and effectively controlling the processing and production cost of the display device on the basis of improving the assembly accuracy of the middle frame 30 and the frame assembly 10.
[0053] As an implementation method that can be independent of or in parallel with the above-mentioned limiting structure, this implementation method constrains and limits the middle frame 30 and the back plate 50 in the front-to-back direction on the display device through the cooperation between the back plate 50 and the frame assembly 10.
[0054] Please refer to Figures 11-12. In the embodiment where the middle frame 30 is arranged on the inner side of the frame assembly 10, the edge of the back panel 50 is arranged to protrude from the outer side of the middle frame 30, that is, in the front and rear directions of the middle frame 30, the projection of the edge of the back panel 50 is located on the outer side of the middle frame 30. When the middle frame 30 is assembled on the inner side of the frame assembly 10, the back panel 50 abuts against the rear side of the frame assembly 10 through the front side of its outer edge, thereby constraining the freedom of movement of the middle frame 30 toward the front side through the mutual limitation of the back panel 50 and the frame assembly 10.
[0055] In one embodiment, the back plate 50 can be configured such that its outer edge surface engages with the outer side surface of the frame assembly 10 to improve the integrity between the components in the display device.
[0056] Please refer to Figures 6 to 8. In one embodiment, the middle frame 30 is provided with a plurality of hanging portions 33 at intervals along its length direction. The hanging portions 33 are provided on the front side of the middle frame 30, that is, on the side of the middle frame 30 away from the back plate 50. The hanging portions 33 extend along the front side of the middle frame 30 to a position close to the glass bracket 20. An optical film 60 is provided between the middle frame 30 and the glass bracket 20. The optical film 60 covers the installation area enclosed by the frame assembly 10, so that the light emitted by the backlight light source installed on the front side of the back plate 50 can pass through the optical film 60 and illuminate the cover assembly 40. A plurality of hanging holes spaced apart from each other are provided on the edge of the optical film 60 corresponding to the positions of the hanging portions 33. The hanging holes on the optical film 60 are respectively hung on the middle frame 30 through the hanging portions 33.
[0057] By implementing the above scheme, the middle frame 30 not only serves as a guide component for assembling the back panel 50 on the frame assembly 10, thereby improving the assembly accuracy of the back panel 50 and the cover assembly 40, but also provides an installation position for the optical film material 60, thereby fixing the optical film material 60 between the middle frame 30 and the glass bracket 20, eliminating the need to add an additional optical film material 60 hanging part 33 between the middle frame 30 and the glass bracket 20, thereby improving the structural compactness of the display device.
[0058] As shown in Figures 3-5 and 11, in order to ensure that the frame assembly 10 and the middle frame 30 have strong structural strength and facilitate the overall assembly of the display device, the middle frame 30 and the frame assembly 10 of this embodiment are assembled through an assembly structure arranged along the inside-outside direction, so that when the middle frame 30 is assembled on the inner side of the frame assembly 10, it can be installed and matched with the frame assembly 10 through the assembly structure.
[0059] In this embodiment, the assembly structure is disposed on the middle frame 30 and the frame structure and extends in the inner and outer directions respectively. When the middle frame 30 relies on the assembly bevel 31 and the guide bevel 11 to realize its alignment on the inner side of the frame assembly 10, the assembly structure between the middle frame 30 and the frame assembly 10 also forms an alignment state. The middle frame 30 can be further assembled through the assembly structure after it is quickly positioned with the frame assembly 10. That is to say, the guiding cooperation between the guide bevel 11 and the assembly bevel 31 can not only quickly determine the relative assembly position between the middle frame 30 and the frame assembly 10, but also realize the accurate alignment of the assembly structure between the two, thereby eliminating the need for the middle frame 30 to undergo a secondary manual alignment to further install and fix it with the frame assembly 10, thereby improving the assembly efficiency of the back panel 50 and the cover assembly 40.
[0060] In a specific embodiment, a first positioning hole 13 is provided on the frame assembly 10, passing through its inner and outer opposite sides, and a first fixing hole 34 is provided on the outer side of the middle frame 30, which is aligned with the first positioning hole 13. The middle frame 30 and the frame assembly 10 can be installed and fixed by a first fixing member 35. The first fixing member 35 includes a first mounting portion 351 and a first abutting portion 352 connected to one end of the first mounting portion 351. The first mounting portion 351 can be movable through the first positioning hole 13 and fixedly connected to the middle frame 30 through the first fixing hole 34. The size of the first abutting portion 352 is larger than the size of the first positioning hole 13, so that the first abutting portion 352 can abut against the outer side of the frame assembly 10.
[0061] In the above embodiment, the first fixing hole 34 and the first mounting portion 351 of the first fixing member 35 can be connected by different fixing methods such as wedging and screwing. For example, when the first fixing hole 34 is a threaded hole, the first fixing member 35 is configured as a bolt that is compatible with the threaded hole structure, the first mounting portion 351 is the threaded section of the bolt, and the first abutment portion 352 is the screw head of the bolt. After the first fixing member 35 moves through the first positioning hole 13 through the first mounting portion 351, it is screwed into the first fixing hole 34, and as the first fixing member 35 cooperates with the first fixing hole 34, finally, the first abutment portion 352 of the first fixing member 35 abuts on the outer side of the frame assembly 10, completing the installation and cooperation between the frame assembly 10 and the middle frame 30. Alternatively, in other embodiments, the first fixing hole 34 and the first mounting portion 351 may also be configured as a socket and a pin, respectively. The first fixing member 35 serving as a pin is fixed to the first fixing hole 34 by interference fit after passing through the first positioning hole 13. As the first fixing member 35 continues to be inserted into the first fixing hole 34, the first abutting portion 352 eventually abuts against the outer side of the frame assembly 10, completing the installation and fit of the middle frame 30 and the frame assembly 10.
[0062] The reason why the first fixing member 35 is assembled from the outside to the inside in this embodiment is that when the middle frame 30 and the frame assembly 10 have completed the initial positioning, the front and rear sides of the display device are respectively blocked by the cover assembly 40 and the back panel 50. The first fixing member 35 cannot enter the frame assembly 10 and the inner side of the middle frame 30 from the front or rear side of the display device to assemble the two. Therefore, the first fixing member 35 is assembled from the outside to the inside of the frame assembly 10, which can facilitate the disassembly and assembly of the display device and reduce the difficulty of disassembly and assembly of the back panel 50 and the cover assembly 40 to a certain extent.
[0063] In one embodiment, since the above-mentioned embodiment adopts the method of assembling the first fixing member 35 from the outside to the inside, one end of the first fixing member 35 (the first abutting portion 352) will be exposed on the outside of the frame assembly 10 through the first positioning hole 13. In order to reduce the impact of the first fixing member 35 on the overall visual effect of the display device, the first fixing member 35 can be set as a countersunk screw, and correspondingly, the hole opening at one end of the first positioning hole 13 away from the first fixing hole 34 is set to a structure corresponding to the countersunk screw structure, so that the first abutting portion 352 can be accommodated in the hole opening at one end of the first positioning hole 13, thereby preventing the first abutting portion 352 from protruding from the surface of the frame assembly 10.
[0064] As an optional embodiment, as shown in Figures 3-5 and 11, the cover assembly 40 includes a glass panel 41 and a display module 42, and the display module 42 is stacked on the rear side of the glass panel 41, and the outer edge of the glass panel 41 protrudes from the edge of the display module 42 so that its outer edge can provide a support position for the above-mentioned glass bracket 20.
[0065] In order to ensure that the glass panel 41 and the display module 42 can be stably supported, the glass bracket 20 includes a first supporting portion 21 and a second supporting portion 22. The glass bracket 20 supports and fixes the glass panel 41 through the first supporting portion 21, and the second supporting portion 22 is located on the inner side of the first supporting portion 21. The second supporting portion 22 is against the side of the display module 42 away from the glass panel 41. In a specific embodiment, in addition to being on the inner side of the first supporting portion 21, the second supporting portion 22 is also located on the rear side of the first supporting portion 21 to form a step structure between it and the first supporting portion 21, ensuring that the second supporting portion 22 can be against the first supporting portion 21 to avoid damage to the display module 42.
[0066] According to the above embodiment, as shown in FIG. 3 and FIG. 4 , the following embodiments take the frame assembly 10 and the glass bracket 20 as an integral part as an example.
[0067] The glass bracket 20 is connected to the front end of the frame assembly 10 and is set at an angle to the frame assembly 10. The glass bracket 20 extends along the inner side of the frame assembly 10 and forms the above-mentioned first supporting portion 21 and second supporting portion 22 on its front side.
[0068] According to any of the above-mentioned embodiments, the cover assembly 40 also includes a glass panel 41 and a touch screen 43. The touch screen 43 is stacked on the rear side of the glass panel 41. The touch screen 43 serves as the touch module described in the above-mentioned embodiment. In the embodiment in which the cover assembly 40 includes the glass panel 41 and the display module 42, the touch screen 43 is located between the glass panel 41 and the display module 42.
[0069] In the above embodiment, a wiring layer 44 electrically connected to the touch screen 43 is further provided between the glass panel 41 and the touch screen 43, and a flexible connection line 45 is provided at the edge of the wiring layer 44. The flexible connection line 45 extends through the outside of the frame assembly 10 to the back panel 50 and is communicated with the main board of the display device. In order to provide certain protection for the flexible connection line 45, the outside of the frame assembly 10 is also covered with a shielding cover 14 that shields the flexible connection line 45.
[0070] In this embodiment, the integrally formed frame assembly 10 and glass bracket 20 are arranged on the left side of the display device, which is used for splicing and cooperating with another display device in the embodiment of the display device. Therefore, the frame assembly 10 and the glass bracket 20 are set as an integral part, which can effectively reduce the width of the frame assembly 10 and the glass bracket 20, so that when the display device is spliced with another display device, the width of the splicing edge formed between the two can be kept in a relatively narrow state, thereby improving the display effect of the display device in the splicing state.
[0071] In order to prevent the flexible connecting line 45 from protruding from the surface of the frame assembly 10 in the above embodiment and affecting the splicing between display devices, in this example, a storage groove 19 extending along the front-to-back direction is recessed on the outer surface of the frame assembly 10. When the flexible connecting line 45 extends from the front side of the glass bracket 20 to the outside of the frame assembly 10, it can be accommodated in the storage groove 19 and protected by covering it with a shielding cover 14. Since the frame assembly 10 on this side is used for splicing with another display device, the provision of an additional shielding cover 14 on the frame assembly 10 will not have a corresponding impact on the overall visual effect of the display device.
[0072] The following embodiment takes the glass bracket 20 and the frame assembly 10 as separate components as an example. In this embodiment, the glass bracket 20 and the frame assembly 10 are detachably connected, and the glass bracket 20 is located on the inner side of the frame assembly 10.
[0073] Specifically, since the cover assembly 40 needs to first form an assembly relationship with the frame assembly 10 during the assembly process of the display device, the glass bracket 20 also needs to be pre-installed on the frame assembly 10 between the middle frame 30 and the frame assembly 10 and form a matching relationship with the cover assembly 40. Therefore, in this embodiment, in order to improve the external visual effect of the frame assembly 10, the glass bracket 20 and the frame assembly 10 are assembled and connected from the inside to the outside to implement the installation and matching, so as to avoid the assembly structure being exposed from the outside of the frame assembly 10.
[0074] It should be noted that in the display device provided in this embodiment, the split frame assembly 10 and the glass bracket 20 structure are arranged on the right side of the display device. The right side of the display device is not configured to be spliced with another display device. Therefore, during the use of the display device, the frame assembly 10 located on the right side of the display device will be exposed to the outside of the entire product device. Therefore, setting the frame assembly 10 and the glass bracket 20 as two relatively independent components can effectively improve the design flexibility of the frame assembly 10, thereby optimizing the appearance of the frame assembly 10 and improving the overall visual effect of the display device located on that side.
[0075] As shown in Figures 3 to 5 and 12, the assembly distance of the middle frame 30 and the frame assembly 10 is similar to that of the above-mentioned middle frame 30. A second positioning hole 24 is provided on the glass bracket 20, which passes through the inner and outer opposite sides thereof. Correspondingly, a second fixing hole 15 is provided on the inner side of the frame assembly 10, which is aligned with the second positioning hole 24. The glass bracket 20 and the frame assembly 10 can be installed and fixed by a second fixing member 16. The second fixing member 16 includes a second mounting portion 161 and a second abutting portion 162 connected to one end of the second mounting portion 161. The second mounting portion 161 can be movably passed through the second positioning hole 24 and fixedly connected to the frame assembly 10 through the second fixing hole 15. The size of the second abutting portion 162 is larger than the size of the second positioning hole 24, so that the second abutting portion 162 can abut against the inner side of the glass bracket 20.
[0076] In the above embodiment, the glass bracket 20 is provided with a mounting plate 23 extending backward at its rear side. The glass bracket 20 is pressed against the inner side of the frame assembly 10 through the mounting plate 23 and a second positioning hole 24 is opened on the mounting plate 23. A second fixing hole 15 is opened on the inner side of the frame assembly 10 pressed against the mounting plate 23, so that the glass bracket 20 is installed and fixed on the frame assembly 10 through the second fixing member 16. By providing a mounting plate 23 that can be pressed against the inner side of the frame assembly 10, the contact area between the glass bracket 20 and the frame assembly 10 can be effectively increased, thereby improving the assembly stability of the glass bracket 20 and the frame assembly 10.
[0077] Continuing with the example of an implementation in which the glass bracket 20 and the frame assembly 10 are separately arranged, the glass bracket 20 is installed on the inner side of the frame assembly 10. In an implementation in which the cover assembly 40 includes a glass panel 41 and a touch screen 43, the touch screen 43 is stacked on the rear side of the glass panel 41. In one embodiment, a wiring layer 44 electrically connected to the touch screen 43 is further provided between the glass panel 41 and the touch screen 43. A flexible connecting line 45 is provided at the edge of the wiring layer 44. The flexible connecting line 45 extends between the glass bracket 20 and the frame assembly 10 to the back panel 50.
[0078] In the embodiment of the separately arranged frame assembly 10 and glass bracket 20, the flexible connecting line 45 can pass through the joint between the glass bracket 20 and the frame assembly 10, ensuring that the wiring layer 44 can communicate with the mainboard of the display device through the flexible connecting line 45 while avoiding the flexible connecting line 45 from being exposed on the outside of the frame assembly 10, ensuring that the frame assembly 10 on this side has a higher aesthetics.
[0079] Please refer to Figures 1 to 5 . The present application also provides a frame assembly 10 , which is applied to the interactive tablet mentioned in the above embodiment. The front side of the frame assembly 10 is provided with a glass bracket 20 for supporting and fixing the cover assembly 40 .
[0080] Specifically, a guide slope 11 is formed on the rear side of the frame assembly 10. The guide slope is located on the inner side of the frame assembly and is tilted outward in the direction from the front to the rear of the frame assembly 10. In the application of the interactive tablet, the guide slope 11 is used to guide the assembly slope 31 of the middle frame 30 during the assembly process of the frame assembly 10 and the middle frame 30, so that the frame assembly 10 and the middle frame 30 form a more stable matching relationship, and subsequent assembly is carried out after the limited matching of the two is completed, so that the frame assembly 10 and the middle frame 30 can ensure a high assembly accuracy between the two through a relatively simple assembly method.
[0081] Please refer to Figures 1 to 5 . The present application also provides a middle frame structure. The side middle frame can also be applied to the interactive tablet mentioned in the above embodiment. The rear side of the middle frame 30 can be installed on the back panel 50 .
[0082] Specifically, an assembly bevel 31 is formed on the front side of the middle frame 30. The assembly bevel is located on the outside of the middle frame 30 and is tilted inward from the front to the rear of the middle frame 30. In the application of the interactive tablet, the assembly bevel 31 is used to guide the guide bevel 11 of the frame assembly 10 during the assembly process of the frame assembly 10 and the middle frame 30, so that the middle frame 30 and the frame assembly 10 form a more stable matching relationship, and subsequent assembly is carried out after the limited matching of the two is completed, so that the frame assembly 10 and the back panel 50 assembled on the middle frame 30 can ensure high assembly accuracy between the two through a relatively simple assembly method.
[0083] Please continue to refer to Figure 4. A limiting portion 12 is convexly provided on the inner side of the frame assembly 10, and the limiting portion is located between the guide slope 11 and the glass bracket 20, while a limiting step 32 is formed on the outer side of the middle frame 30 in front of the assembly slope 31. In the application of the interactive tablet, when the frame assembly 10 and the middle frame 30 are guided and positioned by the above-mentioned guide slope 11 and the assembly slope 31, the limiting portion 12 and the limiting step 32 can respectively define the assembly position of the frame assembly 10 and the middle frame 30. When the two are assembled in a direction close to each other until the limiting portion 12 and the limiting step 32 are against each other, it is determined that the frame assembly 10 and the middle frame 30 are in a relatively correct assembly position.
[0084] Subsequently, the frame assembly 10 and the middle frame 30 can be further assembled and fixed by corresponding assembly components, thereby completing the assembly of the interactive flat panel machine.
[0085] To sum up, the display device sets a guide structure between the frame assembly 10 and the middle frame 30, so that during the assembly process of the back panel 50 and the cover assembly 40, the two can be guided to the correct assembly position through the guide bevel 11 and the assembly bevel 31, which is conducive to the rapid assembly of the back panel 50 and the cover assembly 40, reduces the assembly difficulty of the display device to a certain extent, and further improves the assembly accuracy of the back panel 50 and the cover assembly 40, meeting the product processing and production requirements and the user experience.
