[0041] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0042] like Figures 1 to 3 As shown, a unit screen provided in one embodiment of this application includes a display module 300 and a cabinet frame, with the display module 300 mounted on the front of the cabinet frame.

[0043] The enclosure frame includes a frame body 100, which includes a middle frame 4, two first carbon fiber tubes 1, two side frames 3, and two second carbon fiber tubes 2. The middle frame 4, side frames 3, and first carbon fiber tubes 1 are spaced apart along a first direction, with the middle frame 4 and the two first carbon fiber tubes 1 located between the two side frames 3. The two second carbon fiber tubes 2 are spaced apart along a second direction, with one second carbon fiber tube 2 connected to one end of the two side frames 3 and the other second carbon fiber tube 2 connected to the other end of the two side frames 3. Figure 1 In this diagram, D1 represents the first direction and D2 represents the second direction.

[0044] The middle frame 4 and the first carbon fiber tube 1 are both connected to two second carbon fiber tubes 2. Both the first carbon fiber tube 1 and the second carbon fiber tube 2 are hollow tubes, and the frame 3 is a die-cast part. The second direction is the height direction of the frame body 100.

[0045] Understandably, compared to die-cast aluminum alloy parts, the hollow first carbon fiber tube 1 and the second carbon fiber tube 2 have lower density and higher strength.

[0046] In this application, two second carbon fiber tubes 2 are spaced apart along a second direction. One second carbon fiber tube 2 is connected to one end of the two side frames 3, and the other second carbon fiber tube 2 is connected to the other side of the two side frames 3 to form a closed square frame structure to bear the main hoisting tension.

[0047] The second carbon fiber tube 2 replaces part of the original die-cast frame body 100. The second carbon fiber tube 2 is a hollow tube. The hollow second carbon fiber tube 2 has low density and high strength. While significantly reducing the overall weight of the frame body 100, it significantly improves the structural strength of the frame body 100 and reduces deformation during hoisting and use.

[0048] Moreover, considering that the square frame structure itself is prone to indentation and torsional deformation in the middle, in this application, a first carbon fiber tube 1 and a middle frame 4 are arranged inside the square frame. The middle frame 4 and the two first carbon fiber tubes 1 are connected to two second carbon fiber tubes 2 to distribute the force on the second carbon fiber tubes 2, improve the overall structural strength and rigidity of the frame body 100, reduce the risk of deformation, so that the unit screen can be hoisted to a higher height, which is also conducive to ensuring the flatness and stability of the display module 300.

[0049] In one embodiment, such as Figure 2 and Figure 3 As shown, one side of the frame 3 has a support surface 31 extending in the second direction, and the support surface 31 supports the back of the display module 300 of the unit screen.

[0050] The first carbon fiber tube 1 and the second carbon fiber tube 2 are further away from the display module 300 relative to the support surface 31. The first carbon fiber tube 1 and the second carbon fiber tube 2 can be used for gripping, so that no additional handle is needed on the frame body 100, thereby further reducing the weight of the cabinet frame.

[0051] In one embodiment, such as Figure 3 As shown, the frame 3 includes a first connector 32, a second connector 34, and a frame body 33. The frame body 33 is located between the first connector 32 and the second connector 34. The first connector 32, the frame body 33, and the second connector 34 are integrally formed.

[0052] Both the first connector 32 and the second connector 34 protrude from the frame body 33 to the side away from the support surface 31. One of the second carbon fiber tubes 2 connects the first connectors 32 of the two frames 3, and the other second carbon fiber tube 2 connects the second connectors 34 of the two frames 3.

[0053] Specifically, the first connector 32, the second connector 34, and the frame body 33 are integrally formed, and the frame 3 does not need to be assembled. The support surface 31 of the integrally formed frame 3 has a high degree of flatness, which provides high support stability for the display module 300.

[0054] Moreover, compared to designing the frame body 33, the first connector 32, and the second connector 34 to have the same cross-sectional dimensions, in this application, while ensuring the overall structural strength of the frame 3, only the dimensions of the first connector 32 and the second connector 34 connected to the second carbon fiber tube 2 are designed to be larger, so as to reduce the volume and weight of the frame 3.

[0055] In one embodiment, such as Figure 3 As shown, the cross-sectional shape of the second carbon fiber tube 2 is rectangular, and the first connector 32 is provided with a first insertion hole with an opening facing the second carbon fiber tube 2, and one end of the second carbon fiber tube 2 is inserted and fixed to the first insertion hole.

[0056] The second connector 34 is provided with a second insertion hole with an opening facing the second carbon fiber tube 2, and the end of another second carbon fiber tube 2 is inserted and fixed to the second insertion hole.

[0057] It is understandable that when the second carbon fiber tube 2 is inserted into the first or second socket, since the cross-sectional shape of the second carbon fiber tube 2 is rectangular, the second carbon fiber tube 2 must be aligned with the orientation of the corresponding socket before it can be inserted. This enables circumferential positioning and effectively prevents relative rotation between the second carbon fiber tube 2 and the first connector 32 or the second connector 34, thereby improving assembly accuracy and connection stability.

[0058] In one embodiment, such as Figure 3 and Figure 6 As shown, a plurality of support members 5 are provided on the first carbon fiber tube 1. The plurality of support members 5 are distributed at intervals along the second direction. Each support member 5 has a first protrusion extending toward the side close to the display module 300. The first protrusion supports the back of the display module 300.

[0059] Since the first carbon fiber tube 1 is farther away from the support surface 31 of the frame 3 than the display module 300, the frame body 100 only supports the two sides of the display module 300 along the first direction through the frame 3. The central area of ​​the display module 300 is prone to collapse and deformation. Therefore, in this application, a support member 5 is provided on the first carbon fiber tube 1, and the first boss of multiple support members 5 is used to support the central area of ​​the back of the display module 300, reducing the deformation of the display module 300 caused by uneven force, thereby improving the flatness and installation stability of the display module 300.

[0060] Furthermore, the first boss of multiple small-volume support members 5 is used to jointly support the display module 300, so as to reduce the volume and weight of all support members 5 while ensuring the support performance of the display module 300.

[0061] In one embodiment, such as Figure 3 As shown, the support 5 is a die-cast part, specifically made of die-cast aluminum alloy. The support 5 also has a first set of connectors connected to the first boss. The first set of connectors is sleeved and fixed on the outside of the first carbon fiber tube 1. The first set of connectors can be glued to the first carbon fiber tube 1 or fixed to the first carbon fiber tube 1 by rivets.

[0062] In one embodiment, such as Figure 3 and Figure 6 As shown, the second carbon fiber tube 2 has a plurality of second protrusions 6 on the side near the display module 300. The plurality of second protrusions 6 are spaced apart along the first direction. The second protrusions 6 are used to support the back of the display module 300.

[0063] Since the second carbon fiber tube 2 is farther away from the display module 300 than the support surface 31 of the frame 3, the frame body 100 only supports the two sides of the display module 300 along the first direction through the frame 3. Therefore, in this application, a plurality of second protrusions 6 are provided on the side of the second carbon fiber tube 2 near the display module 300. The plurality of second protrusions 6 are used to support the two sides of the display module 300 along the second direction, reducing the deformation of the display module 300 caused by uneven force, thereby improving the flatness and installation stability of the display module 300.

[0064] In one embodiment, such as Figure 3 and Figure 7 As shown, the frame body 100 also includes a positioning pin 7, which is fixed on one side of the frame body 100 along the second direction, and a positioning hole is provided on the other side of the frame body 100 along the second direction.

[0065] The positioning pin 7 extends outward along the second direction toward the outer side of the frame body 100, and the positioning pin 7 is directly opposite the junction of the first carbon fiber tube 1 and the second carbon fiber tube 2.

[0066] In two adjacent box frames assembled along the second direction, the positioning pin 7 on one box frame is adapted to be inserted into the positioning hole of the other box frame.

[0067] Specifically, during the assembly of two adjacent box frames, precise positioning is achieved through the positioning pin 7 and the positioning hole, while avoiding misalignment between the two adjacent box frames.

[0068] It is understandable that the unit screen mainly bears and transmits force through the first carbon fiber tube 1 and the second carbon fiber tube 2. The positioning pin 7 is set at the junction of the first carbon fiber tube 1 and the second carbon fiber tube 2 so that the force between adjacent box frames can be directly transmitted to the main load-bearing parts, thereby improving the stability of the overall structure.

[0069] In one embodiment, such as Figure 3 As shown, a third connector 8 is fixed to the end of the first carbon fiber tube 1. The third connector 8 is provided with a through hole that runs through the first direction. The third connector 8 is sleeved and fixed to the outside of the second carbon fiber tube 2 through the through hole.

[0070] When assembling the frame body 100, the second carbon fiber tube 2 is passed through the through hole of the third connector 8 of each first carbon fiber tube 1, which can realize the assembly of the first carbon fiber tube 1 and the second carbon fiber tube 2. The operation is simple and the assembly efficiency is high.

[0071] Compared to the first carbon fiber tube 1 being directly inserted into the second carbon fiber tube 2, in this application, the first carbon fiber tube 1 is connected to the second carbon fiber tube 2 by means of the third connector 8, which eliminates the need to cut grooves on the tube wall of the second carbon fiber tube 2. This avoids significantly reducing the structural strength of the frame body 100 due to damage to the structure of the second carbon fiber tube 2 itself, and helps the frame body 100 maintain the preset structural strength.

[0072] In one embodiment, the second boss 6, the third connector 8, and the positioning pin 7 are integrally formed, specifically by die casting.

[0073] In one embodiment, such as Figure 3 As shown, the cross-section of the first carbon fiber tube 1 is circular. The circular first carbon fiber tube 1 is more aesthetically pleasing and easier to hold.

[0074] In one embodiment, the end of the first carbon fiber tube 1 is fixedly connected to the third connector 8 by a rivet. The third connector 8 includes a second socket and a third socket. The second socket is provided with the aforementioned through hole, and the third socket is provided with an opening extending in a second direction. The end of the first carbon fiber tube 1 is inserted into the opening, and the rivet passes through the side wall of the third socket and is riveted into the first carbon fiber tube 1.

[0075] In one embodiment, such as Figure 2 and Figure 3 As shown, the enclosure frame also includes a rear cover 9, and the middle frame 4 has a receiving cavity 41 with an opening on one side. The receiving cavity 41 is used to receive the power supply and adapter board of the unit screen, and the rear cover 9 is detachably sealed to the opening of the receiving cavity 41.

[0076] Specifically, the rear cover 9 is equipped with a power aviation socket and a signal aviation socket. The power aviation socket and the signal aviation socket are electrically connected to the adapter board. External power is input through the power aviation socket, and external signals are input through the signal aviation socket. After being converted and distributed by the adapter board, they are transmitted to the power supply, which performs voltage conversion and voltage regulation output to provide a stable working power supply and signal transmission channel for the unit screen.

[0077] In one embodiment, such as Figure 2 and Figure 3 As shown, the back cover 9 is fastened to the middle frame 4. The middle frame 4 is provided with a lifting member 10 on at least one side along the first direction. The middle part of the lifting member 10 is rotatably mounted on the middle frame 4. The lifting member 10 has a top head and a handle arranged opposite to each other. The rotatable connection point between the lifting member 10 and the middle frame 4 is located between the top head and the handle.

[0078] The back cover 9 is provided with a top lifting groove 91, and the handle can be rotated under the action of external force so that the top lifting head can be turned into the top lifting groove 91 and lift the back cover 9.

[0079] Since the back cover 9 is clipped onto the middle frame 4, the operator needs to overcome the clamping force between the back cover 9 and the middle frame 4 to remove the back cover 9, which is quite laborious. Therefore, in this application, a lifting member 10 is provided on the back cover 9. By turning the handle, the lifting member 10's top tilting head is tilted up, thereby overcoming the clamping force between the back cover 9 and the middle frame 4 and lifting the back cover 9, so that the operator can directly remove the back cover 9.

[0080] In one embodiment, such as Figure 2 and Figure 3 As shown, the back cover 9 has a buckle on at least one side along the first direction, and a hook is provided at one end of the buckle. Correspondingly, the middle frame 4 has a slot. When the back cover 9 covers the opening of the receiving cavity 41 of the middle frame 4, the hook is engaged in the slot.

[0081] In one embodiment, such as Figure 1 and Figure 2 As shown, the box frame also includes a windproof frame 200, which is configured to be able to be unfolded or retracted on the back side of the frame body 100.

[0082] The existing unit screens have a fixed unfolded posture for the windproof frame 200. When transporting the unit screens, in order to reduce the space occupied by the unit screens during transportation, the windproof frame 200 is usually removed from the frame body 100 and reassembled after being transported to the installation site, resulting in low installation efficiency of the unit screens and display devices.

[0083] The windproof frame 200 of this application can be unfolded or folded on the back side of the frame body 100. Therefore, when transporting the unit screen, the windproof frame 200 can be folded on the back side of the frame body 100 to reduce the overall transport space occupied by the unit screen. After the unit screen is transported to the installation site, only the windproof frame 200 needs to be unfolded. The entire transportation process does not require disassembling and reassembling the windproof frame 200, thereby improving the installation efficiency of the unit screen and display device.

[0084] In one embodiment, such as Figure 1 and Figure 2 As shown, the back side of the frame body 100 has a first connection position 101 and a second connection position 102, which are disposed on opposite sides of the frame body 100 along a first direction.

[0085] like Figures 4 to 6 As shown, the windproof frame 200 includes a support rod 202, a first component 201 and a second component 203. The support rod 202 extends along a second direction, and the first component 201 and the second component 203 are located on opposite sides of the support rod 202 in a first direction.

[0086] The first component 201 includes a first movable rod 2011, one end of which is hinged to the first connection position 101, and the other end of which is fixedly connected to the support rod 202.

[0087] The second component 203 includes a locking member, a second movable rod 2031, a third movable rod 2032, and a connecting seat 2033. The connecting seat 2033 has a first hinge position and a second hinge position. One end of the second movable rod 2031 is hinged to the support rod 202, and the other end of the second movable rod 2031 is hinged to the first hinge position. One end of the third movable rod 2032 is hinged to the second hinge position, and the other end of the second movable rod 2031 is hinged to the second connecting position 102.

[0088] The windproof frame 200 has a folded state and an unfolded state. In the unfolded state, as... Figure 1 As shown, the support rod 202 is positioned away from the frame body 100, and the locking member can lock the second movable rod 2031 and the third movable rod 2032 so that the first component 201 and the second component 203 tilt to support the support rod 202.

[0089] like Figure 6 As shown, in the retracted state, the support rod 202, the first movable rod 2011, the second movable rod 2031, and the third movable rod 2032 are attached to the back of the frame body 100.

[0090] Specifically, when the windproof frame 200 is retracted, the locking mechanism is unlocked, and the support rod 202 is pushed towards the frame body 100. The support rod 202 and the first movable rod 2011 rotate around the first connecting position 101, thereby driving the third movable rod 2032 to rotate around the second connecting position 102 to the side away from the first connecting position 101. The third movable rod 2032 gradually approaches the back of the frame body 100, and the second movable rod 2031, which moves with the support rod 202 and the third movable rod 2032, gradually approaches the back of the frame body 100 until the support rod 202, the first movable rod 2011, the second movable rod 2031, and the third movable rod 2032 are in contact with the back of the frame body 100. The windproof frame 200 switches to the retracted state. The windproof frame 200 in the retracted state has a smaller overall volume and occupies less space, so it can be transported with the frame body 100 without reassembling after transportation, thus improving the installation efficiency of the unit screen and display device.

[0091] In one embodiment, such as Figure 4 and Figure 5 As shown, the hinge axes of the first movable rod 2011, the second movable rod 2031, and the third movable rod 2032 all extend along the second direction.

[0092] The first movable rod 2011, the second movable rod 2031, and the third movable rod 2032 swing and move in a plane perpendicular to the second direction. All the movable rods move in the same plane of motion, with no spatial misalignment or lateral interference between them. This ensures that the movement trajectory of the support rod 202, the connecting seat 2033, and each movable rod is stable and the transmission is reliable, avoiding movement deviation, jamming, or abnormal noise caused by multi-directional hinges.

[0093] In one embodiment, such as Figure 4 and Figure 5 As shown, the locking component includes a locking plate 2035 and a locking pin 2034. One end of the locking plate 2035 along the first direction is fixedly connected to the second movable rod 2031, and the other end of the locking plate 2035 along the first direction is provided with a connecting hole. The third movable rod 2032 is provided with a first locking hole.

[0094] In the unfolded state, the first locking hole and the connecting hole are connected, and the locking pin 2034 can pass through the connecting hole and be inserted into the first locking hole.

[0095] Specifically, during the unfolding or retraction of the windproof frame 200, the locking pin 2034 is not inserted into the first locking hole. The locking pin 2034 can be inserted into the connecting hole. The locking plate 2035 only moves with the second movable rod 2031. When it is necessary to lock the second movable rod 2031 and the third movable rod 2032, only one locking pin 2034 needs to be inserted into the connecting hole of the locking plate 2035 and the first locking hole of the third movable rod 2032. This can restrict the relative movement between the second movable rod 2031 and the third movable rod 2032, so that the second movable rod 2031 and the third movable rod 2032 can be locked with only one locking pin 2034, reducing the number of locking pins 2034 and the number of locking operations, and improving the locking efficiency.

[0096] In addition, one embodiment of this application also provides a box frame, the structure of which is the same as that of the box frame in any of the above embodiments, and will not be described again here.
