[0053] Combined with Figure 1 and Figure 2 , the display screen provided in this application includes a frame body 100, a display unit 200, and a support assembly 300. The frame body 100 has an inner cavity. A support 102 is provided on the back of the frame body 100. The support 102 has at least two first connection parts 103 spaced apart along the height direction Y. The support 102 also has a positioning part 104 corresponding to each first connection part 103 one by one. The display unit 200 is installed in the inner cavity. The support assembly 300 includes a support base 310 and a support frame 320. The bottom of the frame body 100 is rotatably installed on the support base 310. One end of the support frame 320 is rotatably installed on the support base 310. The other end of the support frame 320 is detachably connected to any one of the first connection parts 103 and is limited to the positioning part 104 corresponding to the first connection part 103.

[0054] Among them, the bottom of the frame body 100 rotates on the support base 310 to adjust the placement form of the frame body 100 and the display unit 200. One end of the support frame 320 rotates relative to the support base 310, and the other end of the support frame 320 rotates accordingly and is limited to the positioning part 104 corresponding to the adjusted frame body 100, realizing the temporary support and fixation of the frame body 100, liberating the hands of on-site assemblers. The assembler detachably connects the other end of the support frame 320 to the first connection part 103 corresponding to the abutted positioning part 104 to fix the position of the adjusted frame body 100; the support frame 320 is detachably connected to the first connection parts 103 at different heights to realize the placement form of the frame body 100 at different inclination angles. The adjustment of the placement form does not require moving the entire display screen or performing complex disassembly operations. When the other end of the support frame 320 is detachably connected to the required first connection part 103, the other end of the support frame 320 is limited to the positioning part 104 corresponding to the required first connection part 103, and the frame body 100 is temporarily supported and fixed, while ensuring the stability of the display screen during the adjustment process, and there is no need for multiple assemblers to lift and support the frame body 100, reducing the operation difficulty.

[0055] In some embodiments, combined with Figure 1 and Figure 2, the support frame 320 has a second connection portion 321. When the end of the support frame 320 is limited to one of the positioning portions 104, the position of the second connection portion 321 corresponds to the position of the first connection portion 103 corresponding to the positioning portion 104. In other words, the distance and orientation between the first connection portion 103 and the corresponding positioning portion 104 are the same as the distance and orientation between the second connection portion 321 and the end of the support frame 320. Since the positional relationship between the second connection portion 321 and the end of the support frame 320 is fixed, the positional relationship between the first connection portion 103 and the corresponding positioning portion 104 is designed accordingly. Thus, when the end of the support frame 320 abuts against the positioning portion 104, the second connection portion 321 naturally aligns with the first connection portion 103, facilitating detachable operation.

[0056] In one embodiment, in combination with Figures 3 to 5 , the first connection portion 103 is a first connection hole, the second connection portion 321 is a second connection hole, and the display screen further includes a first rotating shaft 410. The first rotating shaft 410 is movably inserted through the first connection hole and the second connection hole. The assembler only needs to align and insert the first rotating shaft 410 into the first connection hole and the second connection hole, without the need for threading or squeezing operations within the connection holes, simplifying the assembly operation.

[0057] Optionally, a detachable limiting block is connected to the end of the first rotating shaft 410. For example, the first rotating shaft 410 is a screw, and a nut is threadedly connected to the end of the screw.

[0058] In one embodiment, in combination with Figures 3 to 5 , the support 102 includes a first connection piece 105 perpendicular to the width direction X. The first connection hole penetrates through the first connection piece 105, and the positioning portion 104 is provided on the side of the first connection piece 105 away from the inner cavity. The side portion of the first connection piece 105 has high support strength and is used to provide the positioning portion 104, which is beneficial for achieving temporary stable support of the frame 100. When the support frame 320 is limited to the side portion of the first connection piece 105, the support frame 320 naturally covers the first connection piece 105, facilitating connection and cooperation with the first connection hole and improving the on-site operation efficiency.

[0059] In one embodiment, in combination with Figures 3 to 5 , the support frame 320 includes a connected second connection piece 322 and a third connection piece 323. The end of the second connection piece 322 is limited to the positioning portion 104, and the third connection piece 323 is substantially perpendicular to the second connection piece 322, improving the structural strength. The second connection hole penetrates through the third connection piece 323. The second connection piece 322 and the third connection piece 323 of the support frame 320 are respectively used for limiting support and detachable connection and installation, each having a large operating space and not interfering with each other, reducing the difficulty of adjusting the installation angle of the frame 100.

[0060] Specifically, when the second connecting piece 322 is vertically limited and pressed against the positioning portion 104 located on the side of the first connecting piece 105, the third connecting piece 323 is roughly perpendicular to the second connecting piece 322, and the third connecting piece 323 and the first connecting piece 105 are basically parallel, which is beneficial for the first rotating shaft 410 to pass through the first connecting piece 105 and the third connecting piece 323 in sequence, and facilitates the assembly and disassembly operations of the first rotating shaft 410.

[0061] In one embodiment, in combination Figures 3 to 5 The positioning portion 104 is a positioning groove, which is located above the corresponding first connecting portion 103, and is used to accommodate the end edge of the support frame 320. In this way, the positioning groove is easy to process and exposed, and the end edge of the support frame 320 abuts against the positioning groove, is wrapped and clamped by the groove wall of the positioning groove, and is naturally limited in the positioning groove, and no structural changes are required to the end of the support frame 320. The rest of the support frame 320 is located below the end of the support frame 320, which is convenient for detachable connection with the first connecting portion 103 located below the positioning groove.

[0062] In some embodiments, in combination Figure 3 and Figure 4 The support seat 310 has a limiting slot 311, the frame 100 abuts against the support seat 310, the bottom of the frame 100 is connected with a fourth connecting piece 106, the fourth connecting piece 106 is movably arranged in the limiting slot 311, and the display screen further includes a second rotating shaft 420, the second rotating shaft 420 is movably arranged in the fourth connecting piece 106 and the support seat 310. The limiting slot 311 allows the frame 100 to rotate around the second rotating shaft 420, and limits the axial deviation of the frame 100 along the second rotating shaft 420, which is conducive to reducing the axial shaking of the frame 100 during the process of adjusting the installation angle.

[0063] In one embodiment, in combination Figure 3 and Figure 4 The support seat 310 includes a first seat body 312 and a second seat body 313. The first seat body 312 has a limiting through groove 311. The second seat body 313 is connected to the first seat body 312. The second seat body 313 is rotatably connected to the support frame 320. The second rotating shaft 420 is movably disposed through the fourth connecting piece 106 and the second seat body 313. The first seat body 312 and the second seat body 313 respectively realize rotation limiting and rotation connection with the frame 100, which facilitates the limiting and connection operations of the fourth connecting piece 106, and reduces the difficulty of rotation assembly between the frame 100 and the support seat 310.

[0064] Specifically, the bottom of the first seat body 312 has an assembly groove 314 , and the second seat body 313 is located in the assembly groove 314 , so as to achieve preliminary positioning of the second seat body 313 in the first seat body 312 , thereby facilitating the connection operation between the second seat body 313 and the first seat body 312 .

[0065] In some embodiments, in combination with Figure 6 , Figure 7 and Figure 8 , the housing 100 includes a rear housing 110 and a cover plate 120. The rear housing 110 includes a first side 111 and a second side 112 which are oppositely arranged. The cover plate 120 is rotatably mounted on the first side 111 or the second side 112 of the rear housing 110. The cover plate 120 and the rear housing 110 enclose an inner cavity, and the display unit 200 is mounted in the inner cavity. During maintenance, a staff member rotates the cover plate 120 to open it around the first side 111 or the second side 112 of the rear housing 110, exposing the front side of the display unit 200, and facilitating the maintenance of the front side components (such as the lamp board) of the display unit 200.

[0066] In one embodiment, the display unit 200 is rotatably mounted on the first side 111 of the rear housing 110. The display unit 200 and the cover plate 120 can be both rotatably mounted on the same side of the rear housing 110, or can be respectively rotatably mounted on different sides of the rear housing 110, which is not limited herein. Among them, after the cover plate 120 is opened, the staff member can continue to rotate the display unit 200 as a whole around the first side 111 of the rear housing 110 to open it, exposing the rear side of the display unit 200, and facilitating the maintenance of the rear side components (such as the power supply) of the display unit 200. When maintaining the front side components of the display unit 200, the cover plate 120 is rotatably supported on the first side 111 or the second side 112 of the rear housing 110, and it is not necessary for multiple staff members to disassemble the cover plate 120 as a whole and carry it horizontally. When maintaining the rear side components of the display unit 200, the display unit 200 is rotatably supported on the first side 111 of the rear housing 110, and it is not necessary for multiple staff members to disassemble the display unit 200 as a whole and carry it horizontally. Since it does not involve the operation requirements of gravity handling and multi-point simultaneous removal, the number of maintenance personnel and the maintenance cost are saved, the disassembly and handling difficulty during maintenance is reduced, the maintenance efficiency is improved, at the same time, the labor intensity of the maintenance operation is reduced, the safety risks such as dropping and bumping during the overall disassembly and handling of the cover plate 120 and the display unit 200 are reduced, and the installation abnormality problems caused by repeated overall disassembly are also avoided.

[0067] In some embodiments, in combination with Figure 6 and Figure 8 , the cover plate 120 is a transparent cover plate, which facilitates the light of the display unit 200 to transmit through the cover plate 120. Optionally, when the cover plate 120 is closed, the part facing the display unit 200 is a transparent part, for example, a transparent acrylic plate is used, and plates such as steel, copper, and aluminum are used around it to improve the structural strength and assembly stability. It can be understood that in other embodiments, the cover plate 120 can be a semi-transparent cover plate 120, which is not specifically limited herein.

[0068] In some embodiments, in combination withFigure 9 and Figure 10 The display unit 200 is rotatably mounted on the rear housing 110 through the first rotating connection member 540, reducing the structural modification amount of the display unit 200 and the rear housing 110, facilitating the modular design of the display unit 200 and the rear housing 110, and moreover, the first rotating connection member 540 bears the rotational friction and wear, which can ensure the structural integrity of the display unit 200 and the rear housing 110.

[0069] Specifically, the first rotating connection member 540 is detachably connected to the display unit 200 and the rear housing 110 respectively, facilitating the maintenance of the rotational connection between the display unit 200 and the rear housing 110, without the need to replace the display unit 200 or the rear housing 110, and reducing the maintenance cost.

[0070] Specifically, the number of the first rotating connection members 540 is multiple, and the multiple first rotating connection members 540 are spaced apart along the height direction Y, realizing uniform overall force on the display unit 200, making the rotation smoother, lighter, and having a high service life.

[0071] Specifically, the first rotating connection member 540 is a hinge structure, and the hinge structure is conducive to improving the simplicity of assembly and the convenience of maintenance and replacement. It can be understood that in other embodiments, the first rotating connection member 540 can be selected as a rotating shaft sleeve structure to realize the rotational connection between the display unit 200 and the rear housing 110, which is not limited herein.

[0072] In some embodiments, in combination with Figure 7 、 Figure 9 and Figure 10 ,the display screen further includes a first mounting member 510. The display unit 200 is fixedly connected to the first mounting member 510, and the first mounting member 510 is rotatably mounted on the first side 111 of the rear housing 110. Thus, the display unit 200 is rotatably mounted on the rear housing 110 through the first mounting member 510. By adapting the rotational connection between the display unit 200 and the rear housing 110 through the first mounting member 510, it is conducive to the modular design and general design of the display unit 200 and the rear housing 110, reducing the modification amount of the rear housing 110 and the display unit 200, and also facilitating the addition of the first mounting member 510 to the existing rear housing 110 and display unit 200 to realize the rotational connection between the two.

[0073] In addition, the first mounting member 510 can be made of a material with high structural strength. The first mounting member 510 can be selected as a copper mounting member, a steel mounting member, or an aluminum alloy mounting member, which is conducive to improving the connection strength, without the need for both the display unit 200 and the rear housing 110 to be made of materials with high structural strength.

[0074] In one of the embodiments, in combination with Figure 7 and Figure 14, the first mounting member 510 is elongated, and the length direction of the first mounting member 510 is consistent with the height direction Y of the rear case 110. The elongated first mounting member 510 occupies less space in the width direction X and the thickness direction Z, avoiding interference with other structures, avoiding occupying the heat dissipation channel, facilitating the rapid heat dissipation of the display screen and the thin and light design. The first mounting member 510 extending in the height direction Y facilitates the display unit 200 to obtain a uniform and reliable rotational support force in the height direction Y.

[0075] In one embodiment, in combination with Figure 10 , the first mounting member 510 includes a first plate member 511, a second plate member 512, and a third plate member 513 connected in sequence. The first plate member 511 is located at the rear side of the display unit 200 and is fixedly connected to the display unit 200, with a large connection area, improving the connection strength, avoiding occupying the rear side space of the display unit 200, and not affecting the display surface of the display unit 200. The third plate member 513 is located on one side of the display unit 200 in the width direction X and is rotatably connected to the rear case 110. The third plate member 513 and the display unit 200 are spaced apart in the width direction X. On the one hand, it avoids occupying the space in the thickness direction Z, facilitating the thin and light design of the display screen. On the other hand, it can increase the connection area and the connection operation space with the rear case 110, and at the same time, it also increases the rotational space of the third plate member 513 relative to the rear case 110, reducing the difficulty of the rotatable connection between the third plate member 513 and the rear case 110.

[0076] Optionally, the first plate member 511 and the third plate member 513 are substantially parallel and spaced apart along the thickness direction Z.

[0077] Optionally, the first plate member 511, the second plate member 512, and the third plate member 513 are integrally formed without assembly, improving the position consistency of the first mounting member 510. For example, the first mounting member 510 is integrally stamped and bent, increasing the overall rigidity of the first mounting member 510.

[0078] In one embodiment, in combination with Figure 10, the display screen further includes a first fastener 610. The first fastener 610 passes through the rear case 110 and the first mounting member 510 from the rear side of the rear case 110 to detachably connect the first mounting member 510 and the rear case 110. In this way, when it is not necessary to rotate the display unit 200, the first fastener 610 is used to detachably and fixedly connect the first mounting member 510 and the rear case 110, enhancing the supporting force of the display unit 200 and preventing the first mounting member 510 and the display unit 200 from accidentally rotating and opening, thus enhancing the stability and safety of the product. When it is necessary to maintain the components on the rear side of the display unit 200, the first fastener 610 is removed from the outside of the rear case 110, facilitating the staff to release the detachable connection relationship between the first mounting member 510 and the rear case 110, so that the first mounting member 510 and the display unit 200 can be conveniently rotated and opened.

[0079] It can be understood that in other embodiments, the first mounting member 510 can be detachably connected to the rear case 110 by means of magnetic attraction, snap connection, etc., which is not limited herein. Alternatively, there may be no detachable connection between the first mounting member 510 and the rear case 110. When in use, the display unit 200 is limited between the cover plate 120 and the rear case 110, and the probability of accidentally rotating and opening is low. When maintaining the components on the front side of the display unit 200, the maintenance effort is small, and the display unit 200 will not rotate and open. Even if it rotates and opens, the components on the front side of the display unit 200 can still be maintained.

[0080] Optionally, the first fastener 610 can be detachably connected to the rear case 110 and the first plate member 511, can be detachably connected to the rear case 110 and the third plate member 513, or there can be two sets of first fasteners 610.

[0081] In one embodiment, in combination with Figure 10 , the first rotating connector 540 is installed on the first mounting member 510, and the first mounting member 510 is rotatably connected to the rear case 110 through the first rotating connector 540.

[0082] Specifically, one end of the first rotating connector 540 is connected to the rear side of the first mounting member 510, and the second end of the first rotating connector 540 is connected to the inner wall of the rear housing 110, so that the first rotating connector 540 is located between the first mounting member 510 and the rear housing 110, making the first rotating connector 540 not exposed, improving the safety of use of the first rotating connector 540, and also facilitating the neatness of the outer surface of the display screen. It avoids the first rotating connector 540 protruding outside the display screen and occupying a large space, which is beneficial to the thin and light design of the display screen, small occupied space, convenient packaging and transportation.

[0083] In some embodiments, in combination with Figure 7 、 Figure 9 and Figure 11 , the display screen further includes a second mounting member 520, the second mounting member 520 is detachably connected to the second side 112 of the rear housing 110, and the second mounting member 520 is fixedly connected to the display unit 200. In this way, when the display unit 200 does not need to be rotated, both sides of the display unit 200 respectively rotate and support the first side 111 of the rear housing 110 and are detachably and fixedly supported on the second side 112 of the rear housing 110, preventing the display unit 200 from accidentally rotating and opening, and enhancing the stability and safety of the product. When it is necessary to maintain the components on the rear side of the display unit 200, the staff releases the detachable connection relationship between the other side of the display unit 200 and the rear housing 110, so that the display unit 200 can be conveniently rotated and opened.

[0084] The display unit 200 realizes detachable connection with the rear housing 110 through the second mounting member 520, avoiding directly opening holes on the display unit 200 and directly connecting with the rear housing 110, reducing the modification amount of the rear housing 110 and the display unit 200, and also facilitating adding the first mounting member 510 to the existing rear housing 110 and display unit 200 to achieve detachable connection between the two. In addition, the second mounting member 520 can be made of a material with high structural strength, which is beneficial to improving the connection strength, and there is no need for both the display unit 200 and the rear housing 110 to be made of materials with high structural strength. The second mounting member 520 can be selected as a copper mounting member, a steel mounting member or an aluminum alloy mounting member.

[0085] It can be understood that in other embodiments, there may be no detachable connection between the other side of the display unit 200 and the rear housing 110. During use, the display unit 200 is limited between the cover plate 120 and the rear housing 110, and the probability of accidentally rotating and opening is low. When maintaining the components on the front side of the display unit 200, the maintenance force is small, and the display unit 200 will not rotate and open. Even if it rotates and opens, the components on the front side of the display unit 200 can still be maintained.

[0086] In one embodiment, the display screen further includes a second fastener 620, which is provided through the rear shell 110 and the second mounting member 520 from the rear side of the rear shell 110 to detachably connect the second mounting member 520 to the rear shell 110. The second fastener 620 is used to realize the detachable fixed connection between the second mounting member 520 and the rear shell 110, thereby enhancing the supporting force of the rear shell 110 on the display unit 200, preventing the display unit 200 from accidentally rotating and opening from the second side 112 of the rear shell 110, and enhancing the stability and safety of the product. When it is necessary to maintain the rear side components of the display unit 200, the second fastener 620 is removed from the outside of the rear shell 110, so that the staff can release the detachable connection between the second mounting member 520 and the rear shell 110, so that the second mounting member 520 and the display unit 200 can be conveniently rotated and opened. It can be understood that the second mounting member 520 can also be detachably connected to the rear shell 110 by means of magnetic attraction, snap-on connection, etc., which is not limited here.

[0087] In one embodiment, in combination Figure 7 The second mounting member 520 is slender, and the length direction of the second mounting member 520 is consistent with the height direction Y of the rear housing 110. The slender second mounting member 520 occupies a small space in the width direction X and the thickness direction Z, avoids interference with other structures, avoids occupying the heat dissipation channel, and is conducive to rapid heat dissipation of the display screen and a light and thin design. The second mounting member 520 extending in the height direction Y is conducive to the display unit 200 to obtain a uniform and reliable connection support force in the height direction Y, reducing deformation and shaking in the height direction Y.

[0088] In one embodiment, in combination Figure 11 The second mounting member 520 includes a fourth plate 521, a fifth plate 522, and a sixth plate 523 connected in sequence. The fourth plate 521 is located at the rear side of the display unit 200 and is fixedly connected to the display unit 200. The connection area is large, the connection strength is improved, and the space at the rear side of the display unit 200 is avoided to be occupied, and the display surface of the display unit 200 is not affected. The sixth plate 523 is located on one side of the display unit 200 in the width direction X, so as to avoid occupying the space in the thickness direction Z, which is conducive to the thin and light design of the display screen. At least one of the fourth plate 521 and the sixth plate 523 is detachably mounted on the second side 112 of the rear shell 110, so as to realize the detachable connection between the second mounting member 520 and the rear shell 110.

[0089] Optionally, the fourth plate 521 and the sixth plate 523 are substantially parallel and spaced apart along the thickness direction Z, so that the second mounting member 520 is bent, which is beneficial to improving its structural strength.

[0090] Optionally, the fourth plate member 521, the fifth plate member 522, and the sixth plate member 523 are integrally formed without the need for assembly, improving the positional consistency of the second mounting member 520. For example, the second mounting member 520 is integrally formed by stamping and bending, increasing the overall rigidity of the second mounting member 520.

[0091] In one embodiment, in combination with Figure 9 and Figure 12 , the display screen further includes a third mounting member 530. The third mounting member 530 is fixedly mounted in the middle of the display unit 200 in the width direction X. The third mounting member 530 is located between the rear side of the display unit 200 and the rear housing 110. The display screen further includes a third fastener 630. The third fastener 630 passes through the rear housing 110 and the third mounting member 530 from the rear side of the rear housing 110 to detachably connect the third mounting member 530 to the rear housing 110. In this way, when the display unit 200 does not need to be rotated, the third mounting member 530 is detachably and fixedly connected to the rear housing 110 by means of the third fastener 630, preventing the display unit 200 from accidentally rotating and opening, enhancing the supporting force of the display unit 200, being able to effectively share the weight and load of the display unit 200, and enhancing the stability and safety of the product. When it is necessary to maintain the components on the rear side of the display unit 200, the third fastener 630 is removed from the outside of the rear housing 110, facilitating the staff to release the detachable connection relationship between the third mounting member 530 and the rear housing 110, so that the third mounting member 530 and the display unit 200 can be conveniently rotated and opened.

[0092] Specifically, the third mounting member 530 is elongated, and the length direction of the third mounting member 530 is consistent with the height direction Y of the rear housing 110. The elongated third mounting member 530 occupies little space in the width direction X and the thickness direction Z, avoiding interference with other structures, avoiding occupying the heat dissipation channel, being beneficial to the rapid heat dissipation of the display screen and the thin and light design. The third mounting member 530 extending in the height direction Y is beneficial for the display unit 200 to obtain a uniform and reliable rotational support force in the height direction Y.

[0093] In some embodiments, in combination with Figure 6 , the cover plate 120 is rotatably mounted on the second side 112 of the rear housing 110, and the cover plate 120 is detachably mounted on the first side 111 of the rear housing 110. Since the cover plate 120 and the display unit 200 are respectively rotated and opened on both sides of the rear housing 110, they can be rotated to a larger angle independently, thus providing a larger operation and maintenance space. The cover plate 120 and the display unit 200 are respectively rotated and opened at different positions, avoiding interference with each other when opened, and making the rotation operation smoother. It can be understood that in other embodiments, the cover plate 120 and the display unit 200 are rotated and opened on the same side of the rear housing 110, which is not limited herein.

[0094] In some embodiments, in combination with Figure 7 , the cover plate 120 is rotatably mounted on the rear housing 110 through a second rotating connector 550, reducing the amount of structural modification of the cover plate 120 and the rear housing 110, facilitating the modular design of the cover plate 120 and the rear housing 110, and the second rotating connector 550 bears the rotational friction and wear, which can ensure the structural integrity of the cover plate 120 and the rear housing 110.

[0095] Specifically, one end of the second rotating connector 550 is connected to the inner side wall of the cover plate 120, and the other end of the second rotating connector 550 is connected to the rear side of the rear housing 110. Due to the connection mode of the second rotating connector 550, the cover plate 120 can be opened at an angle close to °, providing a larger maintenance operation space. The second rotating connector 550 is beneficial to improving the simplicity of assembly and the convenience of maintenance and replacement. It can be understood that in other embodiments, the cover plate 120 can be rotatably mounted on the rear housing 110 by means of a rotating shaft sleeve, which is not limited herein.

[0096] Specifically, the number of the second rotating connectors 550 is multiple, and the multiple second rotating connectors 550 are spaced along the height direction Y, so that the overall force on the cover plate 120 is uniform, the rotation is smoother, lighter, and the service life is high.

[0097] Specifically, the second rotating connector 550 is a hinge structure, and the hinge structure is beneficial to improving the simplicity of assembly and the convenience of maintenance and replacement. It can be understood that in other embodiments, the second rotating connector 550 can be selected as a rotating shaft sleeve structure to realize the rotational connection between the cover plate 120 and the rear housing 110, which is not limited herein.

[0098] In one of the embodiments, in combination with Figure 10 , the display screen further includes a fourth fastener 640, and the fourth fastener 640 is detachably connected between the cover plate 120 and the rear housing 110. Thus, when the display unit 200 does not need to be rotated, the cover plate 120 and the rear housing 110 are detachably and fixedly connected by means of the fourth fastener 640, enhancing the supporting force of the cover plate 120. When the front components of the display unit 200 need to be maintained, the fourth fastener 640 is detached from the outside of the rear housing 110, which facilitates the staff to release the detachable connection relationship between the cover plate 120 and the rear housing 110, so that the cover plate 120 can be conveniently rotated and opened.

[0099] In some embodiments, in combination with Figure 13, a first heat dissipation cavity 121 is defined between the cover plate 120 and the display unit 200. First ventilation holes 122 are provided on both the upper side and the lower side of the cover plate 120 to communicate the first heat dissipation cavity 121 with the outside. Through the natural air duct formed by opening holes above and below, compared with the traditional forced air cooling or liquid cooling heat dissipation methods, natural air duct heat dissipation does not require additional energy consumption, which is both environmentally friendly and energy-saving. Utilizing the action of cold and hot gravity, hot air can naturally rise and be discharged from the upper first ventilation holes 122, while cold air enters from the lower first ventilation holes 122, forming effective air convection, shortening the heat dissipation path, increasing the wind speed, and thus significantly improving the heat dissipation effect, especially for the heat dissipation of the front-side components of the display unit 200.

[0100] A good heat dissipation system can reduce the operating temperatures of the display unit 200 and the cover plate 120, reduce aging and damage caused by high temperature, thereby extending the service life of the product, reducing the problem of aging and yellowing of the cover plate 120 caused by temperature, and maintaining the clarity and color vividness of the display effect.

[0101] In some embodiments, in combination with Figure 13 , a second heat dissipation cavity 113 is defined between the rear shell 110 and the display unit 200. Second ventilation holes 114 are provided on both the upper side and the lower side of the rear shell 110 to communicate the second heat dissipation cavity 113 with the outside, constituting an effective natural air duct, which is conducive to quickly taking away the heat generated by the rear-side components of the display unit 200, such as receiving cards, power supplies, ICs, etc., and avoiding the performance degradation or damage of the display unit 200 caused by high temperature. Compared with the traditional forced air cooling or liquid cooling heat dissipation methods, natural air duct heat dissipation does not require additional energy consumption, which is both environmentally friendly and energy-saving.

[0102] In this embodiment, the inner cavity of the frame body 100 is divided into a first heat dissipation cavity 121 and a second heat dissipation cavity 113 by the display unit 200.

[0103] In some embodiments, in combination with Figure 14 and Figure 15 , the display screen further includes a back box assembly 710. One of the lower end of the back box assembly 710 and the rear shell 110 is provided with a buckle 711, and the other is provided with a card hole 115, so that the back box assembly 710 can be inclined and suspended on the rear side of the rear shell 110. When maintenance personnel perform installation, debugging or maintenance, they can easily incline and suspend the back box assembly 710 without overall disassembly and transportation of the back box assembly 710, thereby reducing the operation difficulty of personnel.

[0104] Specifically, the upper end of the back box assembly 710 is detachably connected to the rear case 110. In this way, when the back box assembly 710 does not need to be maintained, the upper end of the back box assembly 710 is detachably connected to the rear case 110, enhancing the support force of the back box assembly 710, preventing the back box assembly 710 from accidentally falling off, and enhancing the stability and safety of the product. When the back box assembly 710 needs to be maintained, since the first connection hole penetrates through the rear case 110, the detachable connection relationship between the upper end of the back box assembly 710 and the rear case 110 is released, so that the back box assembly 710 is inclined and suspended at the rear side of the rear case 110.

[0105] It can be understood that the upper end of the back box assembly 710 can be detachably connected to the rear case 110 by means of fasteners, magnetic attraction, snap connection, etc., which is not limited herein.

[0106] In some embodiments, the rear case 110 is an aluminum alloy case or a steel alloy case, etc., which is not limited herein.

[0107] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
