[0031] One embodiment is, Figure 1 , 2As shown in Figures 6 and 7, a corner protection mechanism includes a mounting bracket 10, a corner protection assembly 20 and a locking assembly 30; wherein, the corner protection assembly 20 is arranged on the mounting bracket 10, and the corner protection assembly 20 includes a corner protection body 210 and a first elastic member 220, the corner protection body 210 is rotatably arranged on the mounting bracket 10, and the corner protection body 210 has a receiving position 210A and a corner protection position 210B; the first elastic member 220 is arranged on the mounting bracket 10, and the first elastic member 220 drives the corner protection body 210 to rotate from the receiving position 210A to the corner protection position 210B. The locking assembly 30 is arranged on the mounting bracket 10, and the locking assembly 30 includes a limit member 310 and a second elastic member 320. The limit member 310 is movably arranged on the mounting bracket 10, and the limit member 310 has a locking position 310A and a release position 310B; the second elastic member 320 is arranged on the mounting bracket 10, and the second elastic member 320 drives the limit member 310 to move from the release position 310B to the locking position 310A, and makes the limit member 310 combined with the corner guard body 210 to keep the corner guard body 210 in the receiving position 210A. When the elastic force of the second elastic member is overcome and the limit member 310 is moved to the release position 310B, the corner guard body 210 is driven by the first elastic member to rotate from the receiving position 210A to the corner guard position 210B. It is understood that when the stopper 310 is at the locking position 310A, the stopper 310 is combined with the corner protector body 210, and the corner protector body 210 is located at the receiving position 210A. When the stopper 310 is at the releasing position 310B, the stopper 310 is separated from the corner protector body 210, and the corner protector body 210 is located at the corner protecting position 210B.

[0032] The above-mentioned corner protection mechanism locks or releases the corner protection body 210 through the locking assembly 30, thereby switching the position of the corner protection body 210, so that the corner protection assembly 20 can achieve the corresponding function of receiving or protecting the corner on the mounting bracket 10. Among them, the corner protection assembly 20 is driven by the first elastic member 220 to switch the position of the corner protection body 210, and the locking assembly 30 is driven by the second elastic member 320 to switch the position of the limiter 310; when in use, the limiter 310 is combined or separated with the corner protection body 210 by elastic switching of the position of the limiter 310, so that the corner protection body 210 can achieve the effect of receiving or protecting the corner. The corner protection mechanism of the present application has a simple structure and is easy to operate; at the same time, the corner protection body 210 is rotatably connected to the mounting bracket 10, and there is no need to store the corner protection body 210 separately, so as to avoid loss.

[0033] In one embodiment, a corner protection mechanism includes part or all of the structures of the following embodiments; that is, the corner protection mechanism includes part or all of the following technical features. In one embodiment, the corner protection mechanism is applied to a display module. In one embodiment not shown in the figure, the display module includes a screen body and a corner protection mechanism, the screen body is arranged on a mounting bracket, and the corner protection body rotates to cover the corner of the screen body, or the corner protection body rotates to separate from the corner of the screen body. Specifically, as Figure 1 , 2 As shown in , 6 and 7, the mounting bracket is located on the back of the screen body, and the corner of the mounting bracket 10 corresponds to the back of the corner of the screen body. When the corner protection body 210 rotates to cover the corner of the mounting bracket 10, the corner protection body 210 covers the corner of the screen body. When the corner protection body 210 rotates to separate from the corner of the mounting bracket 10, the corner protection body 210 is separated from the corner of the screen body. The corner protection body 210 has a receiving position 210A and a corner protection position 210B, and the limiter 310 has a locking position 310A and a releasing position 310B. When the limiter 310 is in the locking position 310A, the limiter 310 is combined with the corner protection body 210, so that the corner protection body 210 corresponds to the receiving position 210A, and the corner protection body 210 is separated from the corner of the screen body, that is, at this time, the corner of the screen body is exposed, so that multiple display modules can be spliced ​​with each other. When the stopper 310 is at the release position 310B, the stopper 310 is separated from the corner protection body 210, so that the corner protection body 210 corresponds to the corner protection position 210B, and the corner protection body 210 covers the corner of the screen body, that is, at this time, the corner protection body 210 protects the corner of the screen body to prevent the corner of the screen body from being damaged. Of course, the corner protection mechanism of the present application is not limited to the display module, but can also be applied to other parts that need to be protected, such as the corners of fragile items such as glass panels and ceramic panels. This is only an example and is not limited.

[0034] In one embodiment, if Figures 1 to 3As shown, the mounting bracket 10 is provided with a receiving cavity 110, and the corner protection body 210 is rotatably disposed in the receiving cavity 110 or separated from the receiving cavity 110. The receiving cavity 110 is provided in the mounting bracket 10 to accommodate the corner protection body 210. Specifically, the corner protection body 210 is rotatably disposed on the mounting bracket 10, and the mounting bracket 10 is provided with a receiving cavity 110. The corner protection body 210 can be rotatably rotated to the receiving cavity 110, and the receiving cavity 110 corresponds to the receiving position 210A, so that the corner protection body 210 can be accommodated. Correspondingly, the corner protection body 210 can be rotatably separated from the receiving cavity 110 and rotated to the corner protection position 210B. It can be understood that in order to protect the corner of the screen body, the corner protection position 210B is the corresponding position outside the corner of the screen body. That is, the corner protection body 210 rotates to the outside of the corner of the screen body, thereby covering the corner of the screen body to achieve the effect of protecting the corner. In one embodiment, the receiving position 210A and the corner protection position 210B are arranged diagonally, so that the corner protection body 210 can be rotated and switched between the receiving position 210A and the corner protection position 210B.

[0035] It can be understood that the corner body has two sides, and the corner of the screen body has two intersecting sides. In order to make the corner protection body 210 fit more closely with the corner of the screen body to achieve a practical corner protection effect, as shown in FIG. Figures 3 to 5 As shown, in one embodiment, the corner protection body 210 includes a first corner protection plate 211 and a second corner protection plate 212 arranged to intersect each other. The first corner protection plate 211 and the second corner protection plate 212 are respectively used to correspond to the outer peripheries of the corners of the screen body, thereby preventing the outer peripheries of the corners of the screen body from being directly hit, so as to achieve the effect of protecting the corners. Accordingly, in order to accommodate the corner protection body 210 and prevent the corner protection body 210 from being damaged, the corner protection body 210 is completely accommodated in the accommodation cavity 110. In one embodiment, the shape and size of the accommodation cavity 110 are arranged corresponding to the corner protection body 210, so that the corner protection body 210 is completely accommodated in the accommodation cavity 110.

[0036] In order to rotate the corner guard body 210, in one embodiment, as Figures 1 to 4As shown, the corner protection assembly 20 includes a rotating shaft 230, which is disposed on the mounting bracket 10, and the axis of the rotating shaft 230 is perpendicular to the rotation path of the corner protection body 210; the corner protection body 210 is rotatably connected to the rotating shaft 230, and the first elastic member 220 drives the corner protection body 210 to rotate along the rotating shaft 230. Specifically, the rotation path of the corner protection body 210 is a path for reciprocating rotation between the receiving position 210A and the corner protection position 210B. By setting the axis of the rotating shaft 230 to be perpendicular to the reciprocating rotation path of the corner protection body 210, the corner protection body 210 can accurately reciprocate between the receiving position 210A and the corner protection position 210B with the rotating shaft 230 as the axis. In order to shorten the rotation distance of the corner protection body 210, in one embodiment, the rotation shaft 230 is set between the receiving position 210A and the corner protection position 210B. By setting the rotation shaft 230 and limiting the position of the rotation shaft 230, the corner protection body 210 can be rotated from the receiving position 210A to the corner protection position 210B.

In one embodiment, the corner protection body 210 is provided with a connecting hole 213, the connecting hole 213 is coaxial with the fixing hole 241, and the rotating shaft 230 is respectively passed through the fixing hole 241 and the connecting hole 213. The rotating shaft 230 is fixed to the mounting bracket 10 through the mounting seat 240, and the corner protection body 210 is directly sleeved on the rotating shaft 230, so that the corner protection body 210 can rotate relative to the mounting bracket 10 around the rotating shaft 230.

[0038] In order to provide power to rotate the corner guard body 210, Figures 3 to 5As shown, in one embodiment, the fixed end of the first elastic member 220 is connected to the mounting bracket 10, and the free end of the first elastic member 220 is connected to the corner protection body 210, and drives the corner protection body 210 to rotate from the receiving position 210A to the corner protection position 210B. Specifically, the fixed end of the first elastic member 220 is fixed to the mounting bracket 10, that is, the fixed end of the first elastic member 220 is stationary relative to the mounting bracket 10; the free end of the first elastic member 220 is connected to the corner protection body 210, that is, the free end of the first elastic member 220 drives the corner protection body 210 to rotate relative to the mounting bracket 10. In one embodiment, the free end of the first elastic member 220 is directly or indirectly connected to the corner protection body 210. For example, the free end of the first elastic member 220 abuts against the corner protection body 210. In one embodiment, the first elastic member 220 is a bidirectional torsion spring. Specifically, one end of the bidirectional torsion spring is fixed to the mounting bracket 10 as a fixed end, and the other end is connected to the corner guard body 210 as a free end. By using the bidirectional torsion spring to elastically generate torque to drive the corner guard body 210 to rotate relative to the mounting bracket 10, the structure is simple, the installation is convenient and the cost is saved. In order to enable the first elastic member 220 to accurately drive the corner guard body 210 to rotate along a preset path, that is, the first elastic member 220 accurately drives the corner guard body 210 to rotate and switch between the corner guard position 210B and the receiving position 210A, in one embodiment, the first elastic member 220 is disposed on the rotating shaft 230, and the free end of the first elastic member 220 is driven to rotate with the rotating shaft 230 as the axis. In one embodiment, the spring coil of the bidirectional torsion spring is sleeved on the rotating shaft 230, so that it drives the corner guard body 210 to rotate with the rotating shaft 230 as the axis.

[0039] In order to fix the fixed end of the first elastic member 220, the fixed end of the first elastic member 220 is made stationary relative to the mounting bracket 10, such as Figures 3 to 5 As shown, in one embodiment, the mounting bracket 10 is provided with a first positioning hole 120, and the fixed end of the first elastic member 220 is penetrated through the first positioning hole 120, so that the fixed end of the first elastic member 220 cannot move.

By arranging the second elastic member 320 and the limiting member 310 in the limiting groove 130, the limiting groove 130 limits the range of movement of the limiting member 310 and guides the limiting member 310 to move in a preset path; at the same time, at least a portion of the limiting member 310 is exposed in the limiting groove 130, so that the limiting member 310 is combined with the corner guard body 210. Specifically, the limiting groove 130 corresponds to the locking position 310A and the releasing position 310B respectively. When the limiting member 310 is arranged in the limiting groove 130, the second elastic member 320 elastically drives the limiting member 310 to move in the limiting groove 130, so that the limiting member 310 switches between the corresponding locking position 310A and the releasing position 310B in the limiting groove 130.

Specifically, the locking hole 214 corresponds to the locking position 310A, and the release hole 215 corresponds to the release position 310B. When the limiting member 310 penetrates the locking hole 214, the limiting member 310 is in the locking position 310A, and the limiting member 310 is combined with the corner protector body 210 through the locking hole 214. When the limiting member 310 moves to the release hole 215, the limiting member 310 is in the release position 310B, and the limiting member 310 is separated from the corner protector body 210 through the release hole 215.

In one embodiment, the limiting portion 313 is used to be combined with or separated from the corner guard body 210. The diameter of the limiting portion 313 is slightly larger than the aperture of the locking hole 214 so that the limiting portion 313 and the locking hole 214 are interference-fitted, thereby combining the limiting portion 313 with the corner guard body 210. At the same time, the diameter of the limiting portion 313 is smaller than the aperture of the release hole 215, so that the limiting portion 313 can quickly enter the release hole 215, thereby separating the limiting portion 313 from the corner protector body 210. In one embodiment, the limiting portion 313 includes a rod body 3131 and a flange 3132 protruding from the outer periphery of the rod body 3131. The rod body 3131 is movably inserted into the locking hole 214 or the release hole 215. The diameter of the rod body 3131 is slightly larger than the aperture of the locking hole 214 and smaller than the diameter of the release hole 215. The diameter of the flange 3132 is larger than the diameter of the rod body 3131, that is, the diameter of the flange 3132 is larger than the diameter of the locking hole 214, and the diameter of the flange 3132 is smaller than the diameter of the release hole 215. By adding the flange 3132, the limiting portion 313 is reliably connected to the corner protector body 210 in the locking hole 214 to prevent loosening, thereby limiting the corner protector body 210 in the receiving position 210A. In one embodiment, the trigger portion 312 is exposed from the limiting groove 130. Specifically, the trigger portion 312 is exposed from the limiting groove 130 in a direction away from the second elastic member 320, so that the user can directly contact the trigger portion 312 and directly apply force to the second elastic member 320. When the user directly presses the trigger portion 312, the second elastic member 320 is squeezed, and the limiting portion 313 enters the release hole 215 from the locking hole 214, thereby changing the limiting portion 313 and the corner protector body 210 from the combined state to the separated state.

[0045] In one embodiment, if Figures 7 to 10 As shown, the limiting member 310 is an integrally formed structure. In one embodiment, the connecting portion 311, the triggering portion 312 and the limiting portion 313 are an integrally formed structure. Through the integrally formed structure, the connecting portion 311, the triggering portion 312 and the limiting portion 313 can be linked simultaneously. The user presses the triggering portion 312, and the triggering portion 312 transmits the force to the connecting portion 311, and the connecting portion 311 applies force to the second elastic member 320 to deform it, thereby driving the limiting portion 313 to move from the locking hole 214 to the release hole 215, so that the limiting portion 313 and the corner guard body 210 are transformed from a combined state to a separated state. The structure is simple, the operation is convenient, and the design is ingenious.

[0046] In one embodiment, if Figure 4 and Figure 7 As shown, the locking assembly 30 further includes a fixing seat 330, which is disposed on the mounting bracket 10. The fixing seat 330 is provided with a limiting hole 331, which is connected to the limiting groove 130, and a portion of the limiting member 310 is exposed from the limiting hole 331, and a portion of the limiting member 310 is located in the limiting groove 130. In one embodiment, the trigger portion 312 is exposed from the limiting hole 331, and the limiting portion 313 is located on a side of the fixing seat 330 close to the second elastic member 320. By providing the fixing seat 330, when the limiting member 310 is separated from the corner guard body 210, the limiting member 310 is fixed in the limiting groove 130 to prevent the limiting member 310 from falling off. In one embodiment, the fixing seat 330 is connected to the mounting bracket 10 by a screw connection member such as a screw.

[0047] The specific structure of the corner protection mechanism is described below with examples.

[0048] In one embodiment, if Figures 2 to 7 As shown, the corner protection mechanism includes a mounting bracket 10, a corner protection assembly 20 and a locking assembly 30. The corner protection assembly 20 includes a mounting seat 240, a rotating shaft 230, a corner protection body 210 and a first elastic member 220. The mounting seat 240 is connected to the mounting bracket 10, and the mounting seat 240 is provided with a fixing hole 241. The corner protection body 210 is provided with a connecting hole 213, and the connecting hole 213 corresponds to the fixing hole 241. The rotating shaft 230 is respectively penetrated through the connecting hole 213 and the fixing hole 241, and the rotating shaft 230 is installed on the mounting bracket 10 through the mounting seat 240. The mounting seat 240 is also provided with a first positioning hole 120, and the mounting seat 240 is provided with a second positioning hole 242, and the second positioning hole 242 corresponds to the first positioning hole 120. The first elastic member 220 is sleeved on the rotating shaft 230, and the first elastic member 220 is a bidirectional torsion spring. The fixed end of the first elastic member 220 is respectively provided with the second positioning hole 242 and the first positioning hole 120, so that the fixed end of the first elastic member 220 is fixed to the mounting bracket 10. The free end of the first elastic member 220 is connected to the corner protection body 210. The first elastic member 220 takes the rotating shaft 230 as the axis, and drives the corner protection body 210 to rotate along the rotating shaft 230 through torque. The mounting bracket 10 is provided with a receiving cavity 110, and the receiving cavity 110 is arranged diagonally with the corner of the screen body. The first elastic member 220 drives the corner protection body 210 to rotate from the receiving position 210A to the corner protection position 210B, that is, the corner protection body 210 rotates from the receiving cavity 110 to cover the corner of the screen body, thereby realizing the protection of the corner of the screen body.

[0049] like Figures 6 to 10The locking assembly 30 includes a second elastic member 320, a limiting member 310 and a fixing seat 330. The mounting bracket 10 is provided with a limiting groove 130. The second elastic member 320 and the limiting member 310 are both arranged in the limiting groove 130. The fixing seat 330 is connected to the mounting bracket 10 and is used to limit the limiting member 310 to prevent the limiting member 310 from escaping from the limiting groove 130. The corner guard body 210 is provided with a release hole 215 and a locking hole 214 that are interconnected. The side of the limiting groove 130 facing the corner guard body 210 is connected with the release hole 215 and the locking hole 214. The limiting member 310 includes a connecting portion 311, a triggering portion 312 and a limiting portion 313. The connecting portion 311 of the limiting member 310 is arranged in the limiting groove 130 and connected to the free end of the second elastic connecting member. The limiting portion 313 passes through the limiting groove 130 to penetrate the release hole 215 or the locking hole 214. The diameter of the limiting portion 313 is slightly larger than the release hole 215 and smaller than the locking hole 214, so that the limiting portion 313 is connected to the locking hole 214 by interference, and the limiting portion 313 is connected to the corner protector body 210 through the locking hole 214; or, the limiting portion 313 is connected to the release hole 215 by gap, and the limiting portion 313 is separated from the corner protector body 210 through the release hole 215. The fixing seat 330 is provided with a limiting hole 331, and the limiting hole 331 is connected to the limiting groove 130, and the triggering portion 312 passes through the limiting hole 331 to be exposed in the limiting groove 130.

[0050] According to the above structure, the receiving process and the corner protecting process of the corner protecting body 210 are described below by way of example.

[0051] In one embodiment, if Figure 2 , 4 As shown in FIGS. 7, 8 and 9, when the corner protector body 210 is at the receiving position 210A, the limiting member 310 of the locking assembly 30 is at the locking position 310A. Specifically, the second elastic member 320 releases elastic force to support the limiting member 310, so that part of the limiting member 310 is exposed in the limiting groove 130. That is, the triggering portion 312 of the limiting member 310 passes through the limiting hole 331 of the fixing seat 330 to be exposed in the limiting groove 130. At the same time, the limiting portion 313 of the limiting member 310 passes through the limiting groove 130 to correspond to the locking hole 214 passing through the corner protector body 210, and the limiting portion 313 is interference-fitted with the locking hole 214 of the corner protector body 210, thereby locking the corner protector body 210, so that the corner protector body 210 is located at the receiving position 210A, that is, the corner protector body 210 is located in the receiving cavity 110. At this time, the free end of the first elastic member 220 of the corner protection assembly 20 is connected to the corner protection body 210. When the corner protection body 210 is limited by the limiter 310, the corner protection body 210 is subjected to the pulling force of the limiter 310, and the free end of the first elastic member 220 is also subjected to the pulling force due to the force transmission. In the accommodation state of the corner protection body 210, the first elastic member 220 stores the corner energy.

[0052] In one embodiment, if Figure 2 , 4 As shown in FIGS. 7, 8 and 10, when the corner protection body 210 is required to protect the corner of the screen body, the limiting member 310 moves to the release position 310B. The user presses the triggering portion 312 of the limiting member 310 to compress the second elastic member 320, and the connecting portion 311 moves along with the deformation of the second elastic member 320, driving the limiting portion 313 to move from the locking hole 214 to the release hole 215. The limiting portion 313 and the release hole 215 are in clearance fit, so that the corner protection body 210 is loosened from the limiting portion 313, and the corner protection body 210 is separated from the limiting member 310. At the same time of separation, the first elastic member 220 releases the above-mentioned stored corner energy, and with the rotating shaft 230 as the axis, the free end of the first elastic member 220 drives the corner protection body 210 to rotate along the rotating shaft 230 to the corner protection position 210B, and the corner protection body 210 is away from the receiving cavity 110 and rotates to the corner of the screen body, thereby realizing the protection of the corner. During the separation, the user releases the trigger portion 312 , and the second elastic member 320 rebounds to restore the limiting member 310 to the locked position.

[0053] Accordingly, when the corner protector body 210 needs to be accommodated, the user presses the trigger portion 312 to first move the limiting member 310 to the release position 310B. Then the corner protector body 210 is rotated in the opposite direction to return the corner protector body 210 to the receiving cavity 110, and at the same time, the limiting member 313 corresponds to the release hole 215 passing through the corner protector body 210. The user releases the trigger portion 312, and the limiting member 310 returns to the locked position, that is, the limiting member 313 returns to the locking hole 214, and the limiting member 313 is connected with the corner protector body 210, thereby fixing the corner protector body 210 in the receiving cavity 110.

[0054] When the corner needs to be protected again, the above operation is repeated. By adopting the above corner protection assembly 20 and locking assembly 30, the operation is simple, the state of the corner protection body 210 is switched quickly and conveniently, and there is no need to accommodate the corner protection body 210 separately, the structure is simple, and the cost is low.

[0055] The present application also provides a display screen, in one embodiment, the display screen includes at least one display module of any of the above embodiments. The display module includes a screen body and a corner protection mechanism of any of the above embodiments.

[0056] When multiple display modules need to be spliced ​​together to form a display screen, the corner protector body of each display module is in the storage position to expose the screen body of each display module, which is convenient for the screen bodies to be spliced ​​together. When the display screen needs to be disassembled and the display modules need to be transported or stored, the corner protector body of each display module is in the corner protection position to protect the corners of each screen body and prevent the corners from being bumped and damaged.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
