[0046] Combination Figure 1 , Figure 2 and Figure 3, the present application provides a display screen. The display screen includes a rear shell 100, a display unit 300 and a cover assembly 400, the display unit 300 is rotatably mounted on the first side 101 of the rear shell 100, and the cover assembly 400 is rotatably mounted on the first side 101 of the rear shell 100 or the second side 102 of the rear shell 100. That is, the display unit 300 and the cover assembly 400 can be rotatably mounted on the same side of the rear shell 100, or can be rotatably mounted on different sides of the rear shell 100, which is not limited here. The display unit 300 is located between the cover assembly 400 and the rear shell 100, that is, in normal use, the display unit 300 rotates to be close to the rear shell 100, and the cover assembly 400 rotates to be close to the rear shell 100, at which time the front and rear sides of the display unit 300 are protected by the cover assembly 400 and the rear shell 100 respectively.

[0047] During maintenance, a staff member rotates the cover plate assembly 400 around the first side 101 of the rear shell 100 or the second side 102 of the rear shell 100 to open it, exposing the front side of the display unit 300, so that the front side components (such as the light panel) of the display unit 300 can be easily maintained. The staff member can continue to rotate the display unit 300 as a whole around the first side 101 of the rear shell 100 to open it, exposing the rear side of the display unit 300, so that the rear side components (such as the power supply) of the display unit 300 can be easily maintained. When maintaining the front side components of the display unit 300, the cover plate assembly 400 is rotatably supported on the first side 101 or the second side 102 of the rear shell 100, and it is not necessary for multiple staff members to disassemble the cover plate assembly 400 as a whole and carry it horizontally. When maintaining the rear side components of the display unit 300, the display unit 300 is rotatably supported on the first side 101 of the rear shell 100, and it is not necessary for multiple staff members to disassemble the display unit 300 as a whole and carry it horizontally. Since it does not involve the operation requirements of gravity handling and simultaneous dismantling of multiple points, the number of maintenance personnel and maintenance costs are saved, the difficulty of disassembly and transportation during the maintenance process is reduced, the maintenance efficiency is improved, and the labor intensity of maintenance operations is reduced. The safety risks such as falling and collision during the overall disassembly and transportation of the cover assembly 400 and the display unit 300 are reduced, and the abnormal installation problems caused by repeated overall disassembly are avoided.

[0048] In some embodiments, in combination Figure 1 and Figure 3 , the cover assembly 400 is a transparent cover, which facilitates the light of the display unit 300 to be transmitted out of the cover assembly 400. Optionally, when the cover assembly 400 is closed, the part facing the display unit 300 is a transparent part, such as a transparent acrylic plate, and steel, copper, aluminum and other plates are used around to improve the structural strength and assembly stability. It can be understood that in other embodiments, the cover assembly 400 can be a semi-transparent cover, which is not specifically limited here.

[0049] In some embodiments, in combination Figure 4 and Figure 5 The display unit 300 is rotatably mounted on the rear shell 100 via the first rotating connection member 510, which reduces the amount of structural modification of the display unit 300 and the rear shell 100, facilitates the modular design of the display unit 300 and the rear shell 100, and the first rotating connection member 510 bears the rotational friction and rotational wear, thereby ensuring the structural integrity of the display unit 300 and the rear shell 100.

[0050] Specifically, the first rotating connector 510 is detachably connected to the display unit 300 and the rear cover 100, respectively, which facilitates the maintenance of the rotating connection of the display unit 300 and the rear cover 100 without replacing the display unit 300 or the rear cover 100, thereby reducing maintenance costs.

[0051] Specifically, there are multiple first rotating connectors 510 , which are spaced apart along the height direction Y, so that the display unit 300 is evenly stressed as a whole, and the rotation is smoother and lighter, with a longer service life.

[0052] Specifically, the first rotating connector 510 is a hinge structure, which is conducive to improving the ease of assembly and the convenience of maintenance and replacement. It can be understood that in other embodiments, the first rotating connector 510 can be a shaft sleeve structure to realize the rotational connection between the display unit 300 and the rear housing 100, which is not limited here.

[0053] In some embodiments, in combination Figure 2 , Figure 4 and Figure 5 The display screen also includes a first mounting member 210, the display unit 300 is fixedly connected to the first mounting member 210, and the first mounting member 210 is rotatably mounted on the first side 101 of the rear shell 100, so that the display unit 300 is rotatably mounted on the rear shell 100 through the first mounting member 210. The first mounting member 210 is adapted to the rotational connection between the display unit 300 and the rear shell 100, which is beneficial to the modular design and universal design of the display unit 300 and the rear shell 100, reducing the amount of modification of the rear shell 100 and the display unit 300, and is also beneficial to adding the first mounting member 210 to the existing rear shell 100 and the display unit 300 to realize the rotatable connection between the two.

[0054] In addition, the first mounting member 210 can be made of a material with high structural strength. The first mounting member 210 can be selected as a copper mounting member, a steel mounting member or an aluminum alloy mounting member, which is beneficial to improve the connection strength without requiring the display unit 300 and the rear shell 100 to be made of a material with high structural strength.

[0055] In one embodiment, in combination Figure 1 and Figure 3The first mounting member 210 is slender, and the length direction of the first mounting member 210 is consistent with the height direction Y of the rear housing 100. The slender first mounting member 210 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 first mounting member 210 extending in the height direction Y is conducive to the display unit 300 to obtain a uniform and reliable rotation support force in the height direction Y.

[0056] In one embodiment, in combination Figure 5 The first mounting member 210 includes a first plate 211, a second plate 212 and a third plate 213 connected in sequence. The first plate 211 is located at the rear side of the display unit 300 and is fixedly connected to the display unit 300. The connection area is large, the connection strength is improved, and the space at the rear side of the display unit 300 is avoided to be occupied, and the display surface of the display unit 300 is not affected. The third plate 213 is located at one side of the display unit 300 in the width direction X and is rotatably connected to the rear shell 100. The third plate 213 and the display unit 300 are spaced apart in the width direction X. On the one hand, it avoids occupying the space in the thickness direction Z, which is conducive to the thin and light design of the display screen. On the other hand, it can increase the connection area and connection operation space with the rear shell 100, and also increase the rotation space of the third plate 213 relative to the rear shell 100, reducing the difficulty of the rotatable connection between the third plate 213 and the rear shell 100.

[0057] Optionally, the first plate 211 and the third plate 213 are substantially parallel and spaced apart along the thickness direction Z.

[0058] Optionally, the first plate 211, the second plate 212 and the third plate 213 are integrally formed without assembly, thereby improving the position consistency of the first mounting member 210. For example, the first mounting member 210 is integrally stamped and bent to increase the overall rigidity of the first mounting member 210.

[0059] In one embodiment, in combination Figure 5The display screen further includes a first fastener 610, which is inserted through the rear shell 100 and the first mounting member 210 from the rear side of the rear shell 100 to detachably connect the first mounting member 210 to the rear shell 100. In this way, when the display unit 300 does not need to be rotated, the first fastener 610 is used to realize the detachable fixed connection between the first mounting member 210 and the rear shell 100, thereby enhancing the supporting force of the display unit 300, preventing the first mounting member 210 and the display unit 300 from being accidentally rotated and opened, and enhancing the stability and safety of the product. When the rear side components of the display unit 300 need to be maintained, the first fastener 610 is removed from the outside of the rear shell 100, which is convenient for the staff to release the detachable connection between the first mounting member 210 and the rear shell 100, so that the first mounting member 210 and the display unit 300 can be conveniently rotated and opened.

[0060] It is understood that in other embodiments, the first mounting member 210 may be detachably connected to the rear housing 100 by means of magnetic attraction, snap-on connection, etc., which is not limited here. Alternatively, a detachable connection may not be provided between the first mounting member 210 and the rear housing 100. When in use, the display unit 300 is limited between the cover assembly 400 and the rear housing 100, and the probability of accidental rotation and opening is low. When maintaining the front part of the display unit 300, the maintenance force is small, and the display unit 300 will not rotate and open. Even if it is rotated and opened, the front part of the display unit 300 can continue to be maintained.

[0061] Optionally, the rear housing 100 has a through first connection hole, the first mounting member 210 has a second connection hole, and the first fastener 610 is detachably connected to the first connection hole and the second connection hole to detachably connect the first mounting member 210 to the rear housing 100. The first fastener 610 is threadedly connected to the second connection hole, and the first fastener 610 can be threadedly connected to the first connection hole or can be movably inserted therethrough.

[0062] Optionally, the first fastener 610 can be detachably connected to the rear shell 100 and the first plate 211, can be detachably connected to the rear shell 100 and the third plate 213, or can be two groups of first fasteners 610, wherein one group of first fasteners 610 is detachably connected to the rear shell 100 and the first plate 211, and the other group of first fasteners 610 is detachably connected to the rear shell 100 and the third plate 213, thereby achieving a detachable connection between the rear shell 100 and the first mounting member 210.

[0063] In one embodiment, in combination Figure 5 The first rotating connection member 510 is installed on the first mounting member 210 , and the first mounting member 210 is rotatably connected to the rear housing 100 through the first rotating connection member 510 .

[0064] Specifically, one end of the first rotating connector 510 is connected to the rear side of the first mounting member 210, and the second end of the first rotating connector 510 is connected to the inner wall of the rear shell 100, so that the first rotating connector 510 is located between the first mounting member 210 and the rear shell 100, so that the first rotating connector 510 is not exposed, thereby improving the safety of use of the first rotating connector 510, and also contributing to the neatness of the outer surface of the display screen, avoiding the first rotating connector 510 protruding from the outside of the display screen and occupying a large space, which is beneficial to the lightweight design of the display screen, taking up little space, and convenient packaging and transportation.

[0065] In some embodiments, in combination Figure 1 , Figure 4 and Figure 6 The display screen further includes a second mounting member 220, which is detachably connected to the second side 102 of the rear shell 100, and the second mounting member 220 is fixedly connected to the display unit 300. In this way, when the display unit 300 does not need to be rotated, the two sides of the display unit 300 respectively rotate to support the first side 101 of the rear shell 100, and are detachably fixedly supported on the second side 102 of the rear shell 100, so as to prevent the display unit 300 from being accidentally rotated and opened, thereby enhancing the stability and safety of the product. When the rear side component of the display unit 300 needs to be maintained, the staff releases the detachable connection between the other side of the display unit 300 and the rear shell 100, so that the display unit 300 can be easily rotated and opened.

[0066] The display unit 300 is detachably connected to the rear housing 100 through the second mounting member 220, avoiding the need to directly make a hole in the display unit 300 and directly connect it to the rear housing 100, reducing the amount of modification to the rear housing 100 and the display unit 300, and also facilitating the detachable connection between the two by adding the first mounting member 210 to the existing rear housing 100 and the display unit 300. In addition, the second mounting member 220 can be made of a material with high structural strength, which is conducive to improving the connection strength, without requiring the display unit 300 and the rear housing 100 to be made of a material with high structural strength. The second mounting member 220 can be selected from copper mounting members, steel mounting members, or aluminum alloy mounting members.

[0067] It is understood that in other embodiments, the other side of the display unit 300 and the rear housing 100 may not be provided with a detachable connection. When in use, the display unit 300 is limited between the cover assembly 400 and the rear housing 100, and the probability of accidental rotation and opening is low. When maintaining the front part of the display unit 300, the maintenance force is small, and the display unit 300 will not rotate and open. Even if it is rotated and opened, the front part of the display unit 300 can continue to be maintained.

[0068] In one embodiment, the display screen further includes a second fastener 620, which is provided through the rear shell 100 and the second mounting member 220 from the rear side of the rear shell 100 to detachably connect the second mounting member 220 to the rear shell 100. The second fastener 620 is used to realize the detachable fixed connection between the second mounting member 220 and the rear shell 100, thereby enhancing the supporting force of the rear shell 100 on the display unit 300, preventing the display unit 300 from accidentally rotating and opening from the second side 102 of the rear shell 100, and enhancing the stability and safety of the product. When it is necessary to maintain the rear side components of the display unit 300, the second fastener 620 is removed from the outside of the rear shell 100, so that the staff can release the detachable connection between the second mounting member 220 and the rear shell 100, so that the second mounting member 220 and the display unit 300 can be conveniently rotated and opened. It can be understood that the second mounting member 220 can also be detachably connected to the rear shell 100 by means of magnetic attraction, snap-on connection, etc., which is not limited here.

[0069] Optionally, the rear housing 100 has a third through connection hole, the second mounting member 220 has a fourth connection hole, and the second fastener 620 is detachably connected to the third connection hole and the fourth connection hole. The second fastener 620 is threadedly connected to the fourth connection hole, and the second fastener 620 can be threadedly connected to the third connection hole or can be movably inserted.

[0070] In one embodiment, in combination Figure 1 The second mounting member 220 is slender, and the length direction of the second mounting member 220 is consistent with the height direction Y of the rear housing 100. The slender second mounting member 220 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 220 extending in the height direction Y is conducive to the display unit 300 to obtain a uniform and reliable connection support force in the height direction Y, reducing deformation and shaking in the height direction Y.

[0071] In one embodiment, in combination Figure 6 The second mounting member 220 includes a fourth plate 221, a fifth plate 222, and a sixth plate 223 connected in sequence. The fourth plate 221 is located at the rear side of the display unit 300 and is fixedly connected to the display unit 300. The connection area is large, the connection strength is improved, and the space at the rear side of the display unit 300 is avoided to be occupied, and the display surface of the display unit 300 is not affected. The sixth plate 223 is located on one side of the display unit 300 in the width direction X, avoiding 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 221 and the sixth plate 223 is detachably mounted on the second side 102 of the rear shell 100, so as to realize the detachable connection between the second mounting member 220 and the rear shell 100.

[0072] Optionally, the fourth plate member 221 and the sixth plate member 223 are substantially parallel and spaced apart along the thickness direction Z, so that the second mounting member 220 is bent, which is beneficial to improving its structural strength.

[0073] Optionally, the fourth plate 221, the fifth plate 222 and the sixth plate 223 are integrally formed without assembly, thereby improving the position consistency of the second mounting member 220. For example, the second mounting member 220 is integrally stamped and bent to increase the overall rigidity of the second mounting member 220.

[0074] Optionally, at least one of the fourth plate 221 and the sixth plate 223 has a fourth connection hole. For example, the fourth plate 221 has a fourth connection hole, and the fourth plate 221 is located between the display unit 300 and the rear shell 100, and is arranged close to the rear shell 100, which is conducive to shortening the connection distance between the fourth plate 221 and the rear shell 100, and simplifying the connection distance of the second fastener 620. For example, the sixth plate 223 has a fourth connection hole, which can increase the connection area and connection operation space with the rear shell 100, and also increase the rotation space of the sixth plate 223 relative to the rear shell 100, reducing the difficulty of the rotatable connection between the sixth plate 223 and the rear shell 100. For another example, the fourth plate 221 and the sixth plate 223 both have a fourth connection hole, and the fourth plate 221 and the sixth plate 223 are both detachably connected to the rear shell 100, which improves the connection strength between the second mounting member 220 and the rear shell 100.

[0075] In one embodiment, in combination Figure 4 and Figure 7 The display screen further includes a third mounting member 230, which is fixedly mounted at the middle of the display unit 300 in the width direction X, and is located between the rear side of the display unit 300 and the rear shell 100. The display screen further includes a third fastener 630, which is passed through the rear shell 100 and the third mounting member 230 from the rear side of the rear shell 100, so as to detachably connect the third mounting member 230 to the rear shell 100. In this way, when the display unit 300 does not need to be rotated, the third mounting member 230 is detachably fixedly connected to the rear shell 100 by means of the third fastener 630, so as to prevent the display unit 300 from being accidentally rotated and opened, and to enhance the supporting force of the display unit 300, so as to effectively share the weight and load of the display unit 300, and enhance the stability and safety of the product. When the rear part of the display unit 300 needs to be maintained, the third fastener 630 is removed from the outside of the rear shell 100, which makes it easy for the staff to release the detachable connection between the third mounting member 230 and the rear shell 100, so that the third mounting member 230 and the display unit 300 can be easily rotated and opened.

[0076] Specifically, the rear shell 100 has a fifth connecting hole that passes through, the third mounting member 230 has a sixth connecting hole, and the third fastener 630 is detachably connected to the fifth connecting hole and the sixth connecting hole to detachably connect the third mounting member 230 to the rear shell 100. It can be understood that in other embodiments, the third mounting member 230 can be detachably connected to the rear shell 100 by means of magnetic attraction, snap-on connection, etc., which is not limited here. Alternatively, there may be no detachable connection between the middle part of the display unit 300 and the rear shell 100, and there is no need to configure the third mounting member 230. When in use, the display unit 300 is limited between the cover assembly 400 and the rear shell 100, and the probability of accidental rotation and opening is low. When maintaining the front part of the display unit 300, the maintenance effort is small, and the display unit 300 will not rotate and open. Even if it is rotated and opened, the front part of the display unit 300 can continue to be maintained.

[0077] Specifically, the third mounting member 230 is slender, and the length direction of the third mounting member 230 is consistent with the height direction Y of the rear housing 100. The slender third mounting member 230 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 third mounting member 230 extending in the height direction Y is conducive to the display unit 300 obtaining a uniform and reliable rotation support force in the height direction Y.

[0078] In some embodiments, in combination Figure 1 , the cover assembly 400 is rotatably mounted on the second side 102 of the rear shell 100, and the cover assembly 400 is detachably mounted on the first side 101 of the rear shell 100. Since the cover assembly 400 and the display unit 300 are respectively rotated and opened on both sides of the rear shell 100, they can be independently rotated to a larger angle, thereby providing a larger operation and maintenance space. The cover assembly 400 and the display unit 300 are respectively rotated and opened at different positions, avoiding mutual interference when opening, making the rotation operation smoother. It can be understood that in other embodiments, the cover assembly 400 and the display unit 300 are rotated and opened on the same side of the rear shell 100, which is not limited here.

[0079] In some embodiments, in combination Figure 6 The cover assembly 400 can be rotatably installed on the rear shell 100 through the second rotating connecting member 520, which reduces the structural changes of the cover assembly 400 and the rear shell 100, is beneficial to the modular design of the cover assembly 400 and the rear shell 100, and the second rotating connecting member 520 bears the rotational friction and rotational wear, which can ensure the structural integrity of the cover assembly 400 and the rear shell 100.

[0080] Specifically, one end of the second rotating connector 520 is connected to the inner side wall of the cover assembly 400, and the other end of the second rotating connector 520 is connected to the rear side of the rear shell 100. Due to the connection method of the second rotating connector 520, the cover assembly 400 can be opened at an angle of nearly 360°, providing a larger maintenance operation space. The second rotating connector 520 is conducive to improving the ease of assembly and the convenience of maintenance and replacement. It can be understood that in other embodiments, the cover assembly 400 can be rotatably mounted on the rear shell 100 by means of a rotating shaft sleeve, which is not limited here.

[0081] Specifically, there are multiple second rotating connectors 520, and the multiple second rotating connectors 520 are spaced apart along the height direction Y, so that the cover assembly 400 is uniformly stressed as a whole, and the rotation is smoother and lighter, and the service life is long.

[0082] Specifically, the second rotating connector 520 is a hinge structure, which is conducive to improving the ease of assembly and the convenience of maintenance and replacement. It can be understood that in other embodiments, the second rotating connector 520 can be selected as a shaft sleeve structure to realize the rotational connection between the cover assembly 400 and the rear shell 100, which is not limited here.

[0083] In one embodiment, in combination Figure 6 , the rear shell 100 has a seventh connecting hole that passes through, the rear side of the cover assembly 400 has an eighth connecting hole, and the display screen further includes a fourth fastener 640, which is detachably connected to the seventh connecting hole and the eighth connecting hole to realize the detachable connection between the cover assembly 400 and the rear shell 100. In this way, when it is not necessary to rotate the display unit 300, the cover assembly 400 and the rear shell 100 are detachably fixedly connected by means of the fourth fastener 640, thereby enhancing the supporting force of the cover assembly 400. When it is necessary to maintain the front part of the display unit 300, since the seventh connecting hole passes through the rear shell 100, the fourth fastener 640 can be removed from the outside of the rear shell 100, which is convenient for the staff to release the detachable connection between the cover assembly 400 and the rear shell 100, so that the cover assembly 400 can be easily rotated and opened.

[0084] Among them, a sleeve can be fixedly set on the inner side of the cover plate assembly 400, and the eighth connecting hole is formed in the sleeve, so there is no need to open a hole in the cover plate assembly 400, and it can be ensured that the eighth connecting hole has a sufficient connecting length.

[0085] In some embodiments, in combination Figure 8A first heat dissipation cavity 430 is enclosed between the cover assembly 400 and the display unit 300, and first air holes 431 are provided on the upper and lower sides of the cover assembly 400 to connect the first heat dissipation cavity 430 with the outside. Compared with the traditional forced air cooling or liquid cooling heat dissipation methods, the natural air duct formed by the upper and lower openings does not require additional energy consumption, which is both environmentally friendly and energy-saving. Utilizing the effect of hot and cold gravity, hot air can naturally rise and be discharged from the first air hole 431 above, while cold air enters from the first air hole 431 below, forming effective air convection, shortening the heat dissipation path, and increasing the wind speed, thereby significantly improving the heat dissipation effect, especially the heat dissipation of the front part of the display unit 300.

[0086] A good heat dissipation system can lower the operating temperature of the display unit 300 and the cover assembly 400, reduce aging and damage caused by high temperature, thereby extending the service life of the product, reducing the aging and yellowing problem of the cover assembly 400 caused by temperature, and maintaining the clarity and color vividness of the display effect.

[0087] In some embodiments, in combination Figure 8 A second heat dissipation cavity 110 is enclosed between the rear shell 100 and the display unit 300. Second air holes 111 are provided on the upper and lower sides of the rear shell 100 to connect the second heat dissipation cavity 110 with the outside, forming an effective natural wind channel, which is conducive to quickly taking away the heat generated by the rear parts of the display unit 300, such as the receiving card, power supply, IC, etc., and avoiding the performance degradation or damage of the display unit 300 caused by high temperature. Compared with traditional forced air cooling or liquid cooling heat dissipation methods, natural wind channel heat dissipation does not require additional energy consumption, which is both environmentally friendly and energy-saving.

[0088] In some embodiments, in combination Fig. 9 and Fig.10 The display screen further includes a back box assembly 710, and one of the lower end of the back box assembly 710 and the rear housing 100 is provided with a buckle 711 and the other is provided with a clamping hole 120, so that the back box assembly 710 can be tilted and hung on the rear side of the rear housing 100. When performing installation, debugging or maintenance, maintenance personnel can easily tilt and hang the back box assembly 710 without having to disassemble the back box assembly 710 as a whole and carry the back box assembly 710, thereby reducing the difficulty of personnel operation.

[0089] Specifically, the upper end of the back box assembly 710 is detachably connected to the rear shell 100. 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 shell 100, thereby enhancing the supporting 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 connecting hole passes through the rear shell 100, the detachable connection relationship between the upper end of the back box assembly 710 and the rear shell 100 is released, so that the back box assembly 710 is tilted and hung on the rear side of the rear shell 100.

[0090] It can be understood that the upper end of the back box assembly 710 can be detachably connected to the rear shell 100 by fasteners, magnetic attraction, snap-on connection, etc., which is not limited here.

[0091] In some embodiments, the rear shell 100 is an aluminum alloy shell or a steel alloy shell, etc., which is not limited here.

[0092] In some embodiments, the display screen further includes a base 720 , and the rear housing 100 is mounted on the base 720 .

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
