[0003] However, in practical applications, LED display devices often face frequent installation or relocation needs, especially in temporary exhibitions, outdoor events, handheld screens, or other non-fixed locations. In these situations, due to the lack of effective support structures, LED display devices in related technologies are prone to tipping over when temporarily placed on the ground when not in use or during transport. This can damage the LED chips in the display module, affecting the normal operation of the LED display device.

[0004] Therefore, LED display devices in related technologies are prone to tipping over when placed on the ground. Utility Model Content

[0005] The main purpose of this utility model is to provide a support structure and display device to solve the problem that LED display devices are prone to tipping over when placed on the ground in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a support structure is provided for supporting the housing of a display device. The support structure includes: a base connected to the rear side of the housing, the base having a first locking hole and a strip-shaped guide hole communicating with the first locking hole; a support member swayably connected to the base to have a storage position and a support position; and a locking member movably connected to the support member. When the locking member is inserted into the first locking hole, the support member is in the support position; when the locking member is located in the strip-shaped guide hole, the support member is guided and engaged with the strip-shaped guide hole through the locking member and switches between the storage position and the support position.

[0007] Furthermore, the diameter of the first locking hole is greater than the width of the strip guide hole; the locking element includes a rod, which includes a first rod segment and a second rod segment connected to the first rod segment. The diameter of the first rod segment is greater than the diameter of the second rod segment, and the diameter of the first rod segment is greater than the width of the strip guide hole. The first rod segment can be inserted into the first locking hole, and the second rod segment can move within the strip guide hole.

[0008] Furthermore, the locking component also includes a connecting rod, which has a socket extending along its axis. The first end of the connecting rod is connected to the support, and the second end of the connecting rod is inserted into the socket. The socket can move relative to the connecting rod.

[0009] Furthermore, the locking element also includes an elastic element disposed between the connecting rod and the insert rod. The elastic element applies an elastic force to the insert rod so that the first rod segment can maintain a plug-in engagement with the first locking hole.

[0010] Furthermore, the locking component also includes a retaining ring sleeved on the insertion rod. When the elastic component applies an elastic force to the insertion rod, the retaining ring engages with the support component to stop.

[0011] Furthermore, the locking component also includes an anti-disengagement disc, which is disposed at the end of the insertion rod, and the diameter of the anti-disengagement disc is larger than that of the first locking hole.

[0012] Furthermore, the support member includes a support plate and a first upright plate and a second upright plate disposed opposite to each other on both sides of the support plate. At least one of the first upright plate and the second upright plate is hinged to the base body. The first end of the connecting rod is connected to the first upright plate. The second upright plate is provided with a through hole, and the insert rod is movably inserted into the through hole.

[0013] Furthermore, the base includes a mounting plate and a third and a fourth upright plate disposed on opposite sides of the mounting plate. The fourth upright plate is hinged to the second upright plate via a hinge shaft. The first locking hole and the strip-shaped guide hole are both disposed on the fourth upright plate. The axis of the strip-shaped guide hole is an arc, and the center of the arc is located on the axis of the hinge shaft.

[0014] Furthermore, the base is also provided with a second locking hole that communicates with the strip guide hole. When the locking member is inserted into the second locking hole, the support member is in the storage position.

[0016] The present invention provides a support structure for supporting the housing of a display device. The support structure includes a base, a support member, and a locking member. The base is connected to the rear side of the housing and has a first locking hole and a strip-shaped guide hole communicating with the first locking hole. The support member is swayably connected to the base to have a storage position and a support position. The locking member is movably connected to the support member. When the locking member is engaged with the first locking hole, the support member is in the support position. When the locking member is located within the strip-shaped guide hole, the support member is guided and engaged with the strip-shaped guide hole through the locking member, switching between the storage position and the support position. Thus, when the support member is in the support position, the support structure can support the rear side of the housing. The locking member fixes the support member in the support position, making the support structure's support of the housing more stable and reliable. The movable connection of the locking member to the support member facilitates switching between the first locking hole and the strip-shaped guide hole. When the locking element is located within the strip-shaped guide hole, the guide hole guides the locking element, allowing it to smoothly switch between the storage and support positions, making the adjustment of the support element more convenient. In this way, the cooperation of the base, support element, and locking element forms a stable support system. When the support element is in the support position, the support structure can support the rear of the cabinet, ensuring the display device remains upright when placed on the ground, reducing the risk of tipping over. Therefore, the technical solution of this application effectively solves the problem of LED display devices easily tipping over when placed on the ground in related technologies.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is actually illustrative only and is in no way intended to limit the present utility model or its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] In this embodiment, as Figures 1 to 7 As shown, the support structure supports the housing 51 of the display device. The support structure includes a base 10, a support member 20, and a locking member 30. The base 10 is connected to the rear side of the housing 51 and has a first locking hole 131 and a strip-shaped guide hole 132 communicating with the first locking hole 131. The support member 20 is pivotally connected to the base 10 to have a storage position and a support position. The locking member 30 is movably connected to the support member 20. When the locking member 30 is engaged with the first locking hole 131, the support member 20 is in the support position. When the locking member 30 is located within the strip-shaped guide hole 132, the support member 20 is guided and engaged with the strip-shaped guide hole 132 through the locking member 30, switching between the storage position and the support position.

[0021] Thus, when the support member 20 is in the supported position, the support structure can support the rear side of the cabinet 51. The locking member 30 can fix the support member 20 in the supported position, making the support structure's support for the cabinet 51 more stable and reliable. The locking member 30 is movably connected to the support member 20, facilitating the switching of the locking member 30 between the first locking hole 131 and the strip guide hole 132. When the locking member 30 is located in the strip guide hole 132, the strip guide hole 132 guides the locking member 30, so that the locking member 30 can smoothly switch between the storage position and the supported position, making the adjustment of the support member 20 more convenient. In this way, through the cooperation of the base 10, the support member 20, and the locking member 30, a stable support system is formed. When the support member 20 is in the supported position, the support structure can support the rear side of the cabinet 51, so that the display device can remain upright when placed on the ground, reducing the risk of the display device tipping over. Therefore, the technical solution of this embodiment effectively solves the problem that LED display devices are prone to tipping over when placed on the ground in related technologies.

[0022] In other embodiments, the locking member 30 is a captive screw movably connected to the support member 20. The captive screw has a large diameter section and a small diameter section. When the large diameter section is inserted into the first locking hole 131, the support member 20 is in a supporting position. When the small diameter section moves in the strip guide hole 132, the support member 20 can switch between a storage position and a supporting position.

[0023] like Figures 5 to 7 As shown, the diameter of the first locking hole 131 is larger than the width of the strip guide hole 132. The locking member 30 includes a rod 31, which includes a first rod segment 311 and a second rod segment 312 connected to the first rod segment 311. The diameter of the first rod segment 311 is larger than the diameter of the second rod segment 312, and the diameter of the first rod segment 311 is larger than the width of the strip guide hole 132. The first rod segment 311 can be inserted into the first locking hole 131, and the second rod segment 312 can move within the strip guide hole 132. In this way, since the diameter of the first rod segment 311 is larger than the width of the strip guide hole 132, the first rod segment 311 can be kept within the first locking hole 131 when not subjected to external force, which facilitates the locking member 30 in restricting the support member 20 to the support position, making the support member 20's support of the housing 51 more stable and reliable. Furthermore, by limiting the diameter of the first rod segment 311, the diameter of the second rod segment 312, the diameter of the first locking hole 131, and the width of the strip guide hole 132, the insertion rod 31 needs to be manually moved when adjusting the position of the support member 20, thus reducing the situation where the locking member 30 automatically unlocks when no external force is applied.

[0024] When unlocking is required, the insert rod 31 is moved along its axis to remove the first rod segment 311 from the first locking hole 131, and the second rod segment 312 is moved into the first locking hole 131 so that the second rod segment 312 can enter the strip guide hole 132. When locking is required, the second rod segment 312 is moved into the first locking hole 131, and the insert rod 31 is moved along its axis to move the first rod segment 311 into the first locking hole 131 so that the first rod segment 311 can be fixed in the first locking hole 131. Through the cooperation of the first rod segment 311 with the first locking hole 131 and the cooperation of the second rod segment 312 with the strip guide hole 132, the locking and unlocking operation of the support member 20 is simplified, improving the user experience.

[0025] It should be noted that the width of the strip guide hole 132 refers to the distance between two hole walls that are arranged opposite each other along the extension direction perpendicular to the strip guide hole 132.

[0026] like Figures 5 to 7 As shown, the locking member 30 also includes a connecting rod 32. The insertion rod 31 has an insertion hole 313 extending along its axis. The first end of the connecting rod 32 is connected to the support member 20, and the second end of the connecting rod 32 is inserted into the insertion hole 313. The insertion rod 31 can move relative to the connecting rod 32. Thus, the connection between the insertion rod 31 and the support member 20 is facilitated by the connecting rod 32 and the insertion hole 313, making the operation of the insertion rod 31 more convenient, reducing the steps required for the user to switch the insertion rod 31, and improving the user experience. Furthermore, the movement of the insertion rod 31 relative to the connecting rod 32 facilitates the switching of the insertion rod 31 between the first locking hole 131 and the strip-shaped guide hole 132.

[0027] like Figures 5 to 7 As shown, the locking member 30 also includes an elastic member 33, which is disposed between the connecting rod 32 and the insert rod 31. The elastic member 33 applies an elastic force to the insert rod 31 so that the first rod segment 311 can maintain a plug-in engagement with the first locking hole 131. The elastic member 33, disposed between the insert rod 31 and the connecting rod 32, provides an automatic reset function after the user adjusts the locking member 30, ensuring that the first rod segment 311 can maintain a plug-in engagement with the first locking hole 131 when no external force is applied. This ensures that the support member 20 is more reliably held in the locked position, while reducing manual adjustment time and improving adjustment efficiency.

[0028] In this embodiment, the elastic element 33 is a spring, which is sleeved on the outside of the connecting rod 32.

[0029] like Figures 5 to 7As shown, the locking member 30 also includes a retaining ring 34 sleeved on the insertion rod 31. When the elastic member 33 applies an elastic force to the insertion rod 31, the retaining ring 34 engages with the support member 20 to stop. The stop engagement between the retaining ring 34 and the support member 20 prevents the insertion rod 31 from separating from the support member 20 under the action of the elastic force. Furthermore, the above-mentioned arrangement effectively prevents the locking member 30 from accidentally shifting during use, further ensuring the stability and reliability of the support member 20 in the supported position.

[0030] like Figures 5 to 7 As shown, the locking member 30 also includes an anti-detachment disc 35, which is disposed at the end of the insertion rod 31, and the diameter of the anti-detachment disc 35 is larger than that of the first locking hole 131. The anti-detachment disc 35 restricts the range of movement of the insertion rod 31, preventing the insertion rod 31 from detaching from the support member 20 during operation, and ensuring the integrity and safety of the support structure.

[0031] like Figures 5 to 7 As shown, the support member 20 includes a support plate 21 and a first upright plate 22 and a second upright plate 23 disposed opposite to each other on both sides of the support plate 21. At least one of the first upright plate 22 and the second upright plate 23 is hinged to the base body 10. The first end of the connecting rod 32 is connected to the first upright plate 22. A through hole 231 is provided on the second upright plate 23, and the insertion rod 31 is movably inserted into the through hole 231. The support member 20, including the support plate 21, the first upright plate 22, and the second upright plate 23, improves the structural strength of the support member 20 and provides more reliable support for the housing 51. The through hole 231 facilitates the insertion of the insertion rod 31 and facilitates the movement of the insertion rod 31 along its axial direction.

[0032] like Figures 5 to 7 As shown, the base 10 includes a mounting plate 11 and a third upright plate 12 and a fourth upright plate 13 disposed opposite to each other on both sides of the mounting plate 11. The fourth upright plate 13 is hinged to the second upright plate 23 via a hinge shaft 40. A first locking hole 131 and a strip-shaped guide hole 132 are both provided on the fourth upright plate 13. The axis of the strip-shaped guide hole 132 is an arc, and the center of the arc is located on the axis of the hinge shaft 40. The arc design of the axis of the strip-shaped guide hole 132, and the matching of the center of the arc with the axis of the hinge shaft 40, ensures the smoothness of the movement of the support member 20 when switching between the supporting position and the storage position, and improves the smoothness of use of the support structure.

[0033] In this embodiment, the housing 51 includes a frame and a power supply box connected to the frame. The mounting plate 11 is connected to the rear surface of the power supply box by bolts. The housing 51 also includes a handle 53 connected to the frame. The display module 52 is fixed to the frame by magnetic attraction.

[0034] like Figures 5 to 7As shown, the base 10 is also provided with a second locking hole 133 that communicates with the strip guide hole 132. When the locking member 30 is inserted into the second locking hole 133, the support member 20 is in the storage position. The second locking hole 133 allows the support member 20 to be fixed in the storage position when it is not in use, reducing the volume of the support structure, making it easier to store and carry. It also protects the support member 20 from damage and facilitates the splicing of multiple boxes 51.

[0035] In this embodiment, the first locking hole 131 and the second locking hole 133 are respectively disposed at both ends of the strip guide hole 132.

[0036] This application also provides a display device, such as... Figures 1 to 4 As shown, the display device includes a housing 51, a display module 52 disposed on the front side of the housing 51, and a support structure. The support structure supports the housing 51 and is the support structure described above. Since the aforementioned support structure can solve the problem of LED display devices easily tipping over when placed on the ground in related technologies, the display device with this support structure can solve the same technical problem.

[0037] In this embodiment, the display device is preferably a handheld screen, and more preferably a transparent screen.

[0038] The inventors discovered that as transparent display technology matures, the application scenarios for LED display devices are expanding from fixed commercial shop windows and museum display cases to areas requiring mobility and flexible interaction, such as temporary product launches, outdoor interactive advertising, mobile command centers, and immersive art exhibitions. In these scenarios, there is an urgent need for a structure that can be flexibly moved, quickly deployed, and stably supported for LED display devices, allowing the support device to be folded when in use. When the LED display device is not in use, the support device can be quickly unfolded, allowing the LED display device to stand upright on the ground to protect the LED chips of the display module from impacts. In related technologies, display modules are typically permanently or semi-permanently fixed to walls or specific structures using bolts or other fasteners. This makes the LED display device unportable and unable to meet the needs of mobile displays. Related technologies also include brackets connected to the housing, which typically consist of a heavy base and a vertical column, with the housing fixed to the top of the column. This results in a large, bulky, and extremely poorly portable design, with a fixed posture that prevents easy relocation. The LED display device in the related technology also includes a T-shaped base frame. The T-shaped base frame is set at the bottom of the cabinet and is fixed to the cabinet by bolts. In this way, the LED display device cannot be arbitrarily spliced ​​when using the T-shaped base frame, but can only be spliced ​​in the left and right direction, which limits the flexibility of the LED display device.

[0039] By applying the technical solution of this embodiment, the support member 20 can switch between the support position and the storage position, which is convenient for moving and displaying, easy to carry and easy to assemble.
