DETAILED DESCRIPTION

[0046] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0049] like Figure 1-Figure 6As shown, in order to reduce the production cost and processing difficulty of the frame component with a commercial display screen, the present embodiment provides a commercial display frame structure, which includes a frame 10 with a sheet metal structure and a display module 20. The frame 10 with a sheet metal structure is specifically a sheet metal part. The frame 10 is arranged on the periphery of the display module 20 as a frame structure of the display module 20. The frame 10 can be a frame structure formed by splicing multiple sections together. The frames are arranged on the outer edge of the display module 20 and match the shape of the outer edge of the display module 20. In general, the shape of the display module 20 in the positive projection direction is a rectangle, which is of course not limited to other special shapes. The length of a section of the frame 10 is generally determined according to the connection structure between the frames 10, and is generally matched with the length of one side edge of the display module 20. Specifically, the length of a single-section frame 10 will be slightly longer or shorter than the corresponding side edge length of the display module 20. When the single-section frame 10 is slightly shorter than the corresponding side edge, the frames 10 can be connected by connecting parts such as corner pieces. When the single-section frame 10 is slightly longer than the corresponding side edge, the frames 10 can be formed into an integrated structure by welding or by directly rolling or bending a section of the frame 10. Taking a rectangular display module 20 as an example, the display module 20 has two long sides and two short sides, respectively, and the frame 10 is arranged around the periphery of the display module 20 in a single-section structure or an integrated structure.

[0050] The frame 10 of the sheet metal structure can be formed by multiple roll forming by a roller press according to the requirements of the frame 10 structure. Compared with the traditional profile frame, the roll forming frame 10 has the characteristics of higher processing efficiency, lower processing difficulty and lighter weight. At the same time, the production cost of the sheet metal is also lower than the processing cost of the profile structure. The installation space 34 occupied by the sheet metal structure is smaller. After being installed on the display module 20, it occupies a smaller proportion on the display module 20, allowing the display device to have a narrower frame structure.

[0051] Specifically, the frame 10 includes a panel 11 and a first bending section 12 formed by bending the lower edge of the panel 11. The panel 11 serves as the outer plate 11 structure of the display module 20. In the horizontal projection direction of the display module 20, its preferred structure is perpendicular to the display surface of the display module 20, and can effectively include the components of the display module 20. The first bending section 12 is bent toward the display module 20, and is preferably set at 90° to the panel 11. Therefore, the extension direction of the first bending section 12 is parallel to the display surface of the display module 20, and can serve as the edge of the display module 20, and together with the panel 11, it plays the role of fixing, protecting and shielding the internal components of the display module 20. Of course, the panel 11 and the first bending section 12 can also make adaptive structural adjustments according to the specific structure of the components in the display module 20, so that the components in the display module 20 can be adapted, installed and fixed in the frame 10.

[0052] A back plate 30 is fixedly provided on the upper edge of the enclosure 11. The back plate 30 is arranged opposite to the first bending section 12, and is specifically fixedly provided on the rear side of the display module 20, and is used to cover the side of the display module 20 away from the display direction, thereby protecting the exposed components on the back of the display module 20. The above-mentioned rear side refers to the side of the display module 20 away from the display direction. The back plate 30 can form a receiving groove 14 for fixing the display module 20 together with the enclosure 11 and the first bending section 12. The display module 20 can set all its components in the receiving groove 14, thereby ensuring the stability of the structure of the display module 20 after the frame is replaced with a sheet metal structure.

[0053] Further, on the basis of the frame 10 adopting the sheet metal structure, in order to increase the stability of the display module 20 structure, the upper edge of the enclosure 11 is bent to form a second bent section 13, and the relative angle between the second bent section 13 and the enclosure 11 is variable to adapt to the structure of the display module 20 component for fixing, and the enclosure 11, the first bent section 12 and the second bent section 13 form an embedding groove 15 for fixing part of the display module 20 or the touch module. Preferably, the second bent section 13 extends toward the display module 20, and the part thereof for forming the embedding groove 15 is in contact with the enclosure 1 1 is arranged at 90 degrees, and the length of the second bent section 13 extending toward the display module 20 is less than the length of the first bent section 12 extending toward the display module 20, so that the accommodating groove 14 of the display device in its positive projection direction (facing the display direction) partially overlaps with the embedding groove 15, so that it can be ensured that after the embedding groove 15 fixes part of the display module 20 or the touch module component, the remaining display module 20 or the entire display module 20 can be fixed in the accommodating groove 14, and the installation of the display module 20 components will not be interfered with due to the embedding groove 15 covering the accommodating groove 14.

[0054] Since the frame 10 with a sheet metal structure replaces the frame with a transmission profile structure, the structural strength of the frame 10 is lower than that of the traditional profile structure. Although the frame 10 can still shield and cover the outer edge of the display module 20, it is difficult for it to withstand a larger impact like a traditional frame. Therefore, in order to enhance the structural strength of the sheet metal structure frame 10, a reinforcing section 16 is formed between the second bending section 13 and the enclosure 11. The reinforcing section 16 can enhance the overall strength of the frame 10 structure, thereby reducing the problem of the frame 10 being easily bent and deformed when subjected to force. Specifically, the reinforcing section 16 described in this example is a dead edge structure, which is commonly known as a frill or ring edge structure in sheet metal structure design. By folding the sheet metal, the structural strength of the sheet metal can be made higher. By rolling and pressing the dead edge between the second bending section 13 and the enclosure 11, it is possible to ensure that the enclosure 11 and the second bending section 13 have a certain degree of anti-deformation ability. At the same time, it is also possible to make the second bending section 13 and the enclosure 11 have a stronger elastic reset ability. When the parts of the display module 20 are installed into the embedding groove 15 or removed from the embedding groove 15, the first folding section 13 is The bent section 12 and the second bent section 13 can exert a certain elastic pressing force on the component in the embedding groove 15, so that the installation of the component is more stable. At the same time, after the component is disassembled and assembled, the second bent section 13, the enclosure 11 and the first bent section 12 will not be structurally damaged due to deformation. Furthermore, the reinforcing section 16 is arranged on the outer edge of the back panel 30 and shielded by the outer edge of the back panel 30, so that the frame 10 forms a frame assembly of the back panel 30 and the display module 20, thereby improving the degree of coordination between the components of the display device and also improving the sealing between the frame 10 and the back panel 30.

[0055] As an expansion plan, a dead edge structure similar to the structure of the above-mentioned reinforcing section 16 can also be set between the first bending section 12 and the enclosure 11, so as to enhance the structural strength between the first bending section 12 and the enclosure 11. However, since the first bending section 12 mainly serves as a shielding component and the main fixing component function lies in the second bending section 13, it is more appropriate to set a reinforcing section 16 between the second bending section 13 and the enclosure 11.

[0056] As a further implementation of the above scheme, the commercial display frame structure also includes a filter strip 40, which is arranged along the length direction of the frame body 10 and embedded in the embedding groove 15. Specifically, the side surfaces of the filter strip 40 embedded in the embedding groove 15 respectively match the inner walls of the first bending section 12, the enclosure 11 and the second bending section 13, thereby improving the stability of the filter strip 40. In order to fix the display module 20, the filter strip 40 is formed with a press platform 41 on the side away from the embedding groove 15, and the components of the display module 20 are fixed between the back plate 30 and the press platform 41. Of course, if the frame assembly of this scheme is not used in the structure of an infrared touch screen, a structure that matches the embedding groove 15 can be directly embedded in the embedding groove 15, and a table structure similar to the above-mentioned press platform 41 is formed on the side away from the embedding groove 15 for fixing other components of the display module 20. Specifically, a central control receiving cavity 42 is formed in the filter strip 40 along its length direction, and an infrared PCB board 43 is arranged in the receiving cavity 42. The infrared emission position of the infrared PCB board 43 is arranged opposite to the light emitting surface of the filter strip 40, so that infrared rays can be emitted from the filter strip 40 and one side of the frame 10, thereby achieving the function of emitting infrared rays.

[0057] Continuing from the above, the display module 20 includes a tempered glass 21, an OC22, a middle frame 23 and a diaphragm assembly 24. The middle frame 23 is installed on the back panel 30 and between the press platform 41 and the back panel 30. Specifically, corresponding mounting holes can be opened on the back panel 30 and the middle frame 23, and the installation is achieved by screws and other components. After the middle frame 23 is installed on the back panel 30, the middle frame 23 first extends a distance in the direction of the first bending section 12 and then extends in the direction of the display module 20, so that the middle frame 23 forms a fixing plate 231 between the back panel 30 and the press platform 41 for supporting and fixing other components of the display module 20. Furthermore, the tempered glass 21 and OC22 are stacked, and OC22 is arranged between the tempered glass 21 and the fixed plate 231. The edge of the tempered glass 21 is pressed between the pressing platform 41 and the fixed plate 231. In practical applications, foam can also be arranged between the tempered glass 21 to make the structure more compact when fixed, and to prevent relative movement between the tempered glass 21 and OC22, thereby avoiding collision between the tempered glass 21 and OC22. OC22 is arranged between the tempered glass 21 and the middle frame 23. The filter strip 40 is provided with a pressing platform 41 for pressing the tempered glass 21, and the edge of the tempered glass 21 is pressed between the pressing platform 41 and OC22. The diaphragm assembly 24 is sandwiched between the fixed plate 231 and the back plate 30. The diaphragm assembly 24 is one of the key components of the liquid crystal display panel, and its function is to provide sufficient brightness and uniformly distributed light sources so that it can display images normally.

[0058] In order to make the fixing state of the back panel 30 on the frame 10 more stable, the side of the second bending section 13 away from the embedding groove 15 forms a supporting surface 131, and the back panel 30 is mounted on the supporting surface 131. After the back panel 30 and the supporting surface 131 are matched, the horizontal height of the side of the back panel 30 away from the embedding groove 15 is lower than the horizontal height of the reinforcing section 16 away from one end of the enclosure 11, forming a feeling that the edge of the back panel 30 is embedded in the frame 10, and also making the structure between the frame 10 and the back panel 30 more compact.

[0059] like Figure 3 and Figure 5 As shown, as one of the implementation modes of the above scheme, the supporting surface 131 includes a fixed section 1311 and a supporting section 1312 which are connected in sequence from one end close to the enclosure 11 to the end away from the enclosure 11. Specifically, the fixed end is connected to the reinforcing section 16. After forming the frill, the reinforcing section 16 re-extends toward the embedding groove 15 to the upper part of the embedding groove 15. The end of the reinforcing section 16 is connected to the fixed end and connected with the fixed ends. After the other end of the fixed end extends toward the display module 20 for a distance, it re-extends upward in the direction away from the embedding groove 15 and forms a structure parallel to the side of the reinforcing section 16 close to the display module 20, so that a part of the reinforcing section 16 is connected to the fixed end to form a "U"-shaped groove structure, which is used to fix to the back panel 30 to limit the freedom of the back panel 30 in the horizontal direction.

[0060] Furthermore, the back panel 30 includes a main body 31 and a limiting portion 32 located at the edge of the main body 31. The limiting portion 32 is preferably bent toward the frame 10 to form a bending structure that can be inserted into the above-mentioned "U"-shaped groove body, and is clamped in the fixed section 1311. The partial structure of the main body 31 is matched with the surface of the support section 1312 so that the main body 31 can be against the support section 1312. A fixing member 50 is provided between the main body 31 and the support section 1312. The fixing member 50 described here can be a fixing member 50 such as a screw or a bolt that can fix the plates to each other. This fixing method can ensure the stability between the back panel 30 and the frame 10, and also make the two detachable, which is different from the welding or bonding solution.

[0061] like Figure 4 and Figure 6As shown, as the second implementation of the above scheme, the support surface 131 is a plane structure. Compared with the support surface 131 with the "U"-shaped groove structure, the support surface 131 with a plane structure is simpler in the processing process. Since the support surface 131 with a "U"-shaped groove structure needs to use a deep and thin roller cutter during the rolling process, the roller cutter can withstand a relatively small pressure under the axial force during the rolling process. If the roller press is unstable, it will easily cause damage to the roller cutter, thereby reducing the mold life, and the product stability and yield rate are also low. Therefore, the support surface 131 with a plane structure can be processed by a wider roller cutter, thereby ensuring that the roller cutter has a longer mold life, thereby improving the stability of product mass production. However, compared with this method, the first method has higher stability between the back plate 30 and the frame 10. The back panel 30 includes a main body 31 and a third bending section 33 formed by bending the edge of the main body 31 toward the support surface 131. The main body 31 is supported on the support surface 131 through the third bending section 33, so that an installation space 34 is formed between the main body 31 and the support surface 131. The installation space 34 can leave enough installation position for the display module 20, so that the display module 20 can be completely placed between the press platform 41 and the back panel 30.

[0062] In the case of the above structure, since there is no corresponding fixing structure between the back plate 30 and the support surface 131 , a fixing member 50 with a certain stabilizing function needs to be provided between the body 31 and the support surface 131 .

[0063] Preferably, a through threaded hole 1313 is provided on the support surface 131, and a fixing hole 35 opposite to the threaded hole 1313 is provided on the back panel 30. After the back panel 30 is clamped on the reinforcing section 16 on the upper edge of the frame 10, the threaded hole 1313 and the fixing hole 35 are concentric in the orthographic projection direction of the display device, so that the fixing member 50 can be inserted into the fixing hole 35 and the threaded hole 1313 at one time to fix the back panel 30 and the frame 10.

[0064] The fixing part 50 is a step screw, and the fixing part 50 includes a screw head 51, a step 52 and a threaded section 53 connected in sequence. When the threaded section 53 is threadedly engaged with the threaded hole 1313, the step 52 abuts against the support surface 131, and the screw head 51 abuts against the main body 31. The step 52 and the screw head 51 are respectively pressed against the support surface 131 and the side of the back plate 30 away from the support surface 131, so that the back plate 30 can be stably fixed on the frame 10.

[0065] As a further implementation of the above solution, the threaded holes 1313 on the supporting surface 131 can be formed by flanging and tapping. The flanging direction extends towards the embedding groove 15. When the light filtering strip 40 is clamped in the embedding groove 15, the flanging can press against the surface of the light filtering strip 40, and the threaded section 53 can also extend out from the threaded hole 1313 to press against the surface of the light filtering strip 40, further improving the stability of the light filtering strip 40.

[0066] As Figure 1 , Figure 7-Figure 10 shown, this embodiment also provides a commercial display frame assembly, including the commercial display frame structure as described above. The frame body 10 of the sheet metal structure is formed by bending process into three adjacent main frames 17 in sequence. Any two adjacent main frames 17 are integrally formed and perpendicular to each other, so that the frame body 10 forms a structure similar to a "冂" shape. At the opposite ends of the frame body 10, and between the ends of the two mutually distant main frames 17, an opening 18 is formed;

[0067] A secondary frame 60 is provided at the opening 18. The secondary frame 60 is perpendicular to the main frames 17 at both ends respectively, so that the commercial display frame assembly is spliced into a structure similar to a "口" shape.

[0068] As Figure 9-10 shown, on one side of the frame body 10, a relief notch 19 for facilitating bending is formed between any two adjacent main frames 17. In the state where the frame body 10 has not been bent yet, the relief notch 19 preferably has a "V" - shaped structure, so that any two adjacent main frames 17 can avoid interfering with each other during the bending process, resulting in deformation of the frame body 10 or failure to achieve the expected structural effect. In the state after the frame body 10 is bent, any two adjacent main frames 17 are perpendicular to each other, so that the relief notch 19 narrows, making the frame body 10 structure more compact and more integral.

[0069] After the frame body 10 is bent, a gap will be formed at the relief notch 19 between any two adjacent main frames 17. This gap can be made into a seamless structure through welding and grinding.

[0070] In this embodiment, the secondary frame 60 can be Figure 7 the sheet metal frame shown or Figure 8 the extruded aluminum profile frame shown.

[0071] Both ends of the secondary frame 60 and both ends of the frame body 10 are connected through an adapter 70.
