[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0027] The most critical concept of the present invention is that when the first driving member rotates, the first driving surface of the first driving member will cooperate with the second driving surface to drive the second driving member to rotate, thereby driving the transmission member to move. When the transmission member moves, it will drive the protective member to move, so that the protective mechanism is withdrawn from the display screen, which is easy to operate.

[0028] Please refer to Figures 1 to 6 A display screen protection device comprises a frame mechanism 100 and a protection mechanism 200, wherein the protection mechanism 200 comprises a control component 1, a drive component 2 and a protection member 4, wherein the drive component 2 comprises a fixing member 21, a first drive member 22, a second drive member 23 and a transmission member 24, wherein the fixing member 21 is fixedly connected to the frame mechanism 100, wherein one end of the first drive member 22 is rotatably arranged relative to the fixing member 21, and the other end of the first drive member 22 is provided with a first drive surface 221, wherein the second drive member 23 is rotatably arranged relative to the fixing member 21, and one end of the second drive member 23 is provided with a second drive surface 231 matched with the first drive surface 221, wherein the transmission member 24 is arranged at the other end of the second drive member 23, and the protection member 4 is fixedly connected to the transmission member 24, wherein the control component 1 controls the first drive member 22 to rotate relative to the fixing member 21.

[0029] From the above description, it can be known that the beneficial effects of the present invention are: when the first driving member is controlled to rotate by the control component, the first driving surface of the first driving member will cooperate with the second driving surface to drive the second driving member to rotate, thereby driving the transmission member to move, and the transmission member will drive the protective member to move when it moves, so that the protective mechanism withdraws from the display screen; when the first driving member moves in the opposite direction, the protective member can protect the frame of the display screen. The main body of the display screen can be protected by designing a frame mechanism, the shape of the frame assembly is compatible with the main shape of the display screen, the protective member can protect the frame of the display screen, and the protective member can be a protective plate to prevent the display screen from being damaged during transportation and storage. The display screen protection device of the present invention is simple to operate, easy to install and disassemble, and has a good protection effect on the display screen.

[0030] Furthermore, the control assembly 1 includes a rocker 11 and a first rotating member 12 , the rocker 11 is fixedly connected to the first rotating member 12 , the fixed member 21 is rotatably mounted on the first rotating member 12 , and the first driving member 22 is fixedly mounted on the first rotating member 12 .

[0031] It can be seen from the above description that controlling the rotation of the first rotating member by means of a rocker is easy to operate, the number of driving components can be set as required, and one rocker can control the movement of multiple driving components at the same time.

[0032] Furthermore, the driving assembly 2 further includes a first elastic restoring member 25 , which is sleeved on the first rotating member 12 , and two ends of the first elastic restoring member 25 are respectively connected to the first driving member 22 and the fixing member 21 .

[0033] From the above description, it can be seen that when the rocker is released, the first driving member will return to its original position under the elastic restoring force of the first elastic restoring member, and no manual operation is required. The first elastic restoring member can be a torsion spring, and its elasticity can be set as needed.

[0034] Furthermore, the driving assembly 2 further includes a second rotating member 26 , and the second driving member 23 is rotatably disposed relative to the fixing member 21 via the second rotating member 26 .

[0035] Furthermore, the driving assembly 2 further includes a second elastic return member 27 , which is sleeved on the second rotating member 26 , and two ends of the second elastic return member 27 are respectively connected to the second driving member 23 and the fixing member 21 .

[0036] It can be seen from the above description that when the first driving member removes the driving force, the second driving member can return to its original position under the elastic restoring force of the second elastic restoring member.

[0037] Furthermore, the driving assembly 2 further includes a connecting member 28 , and two ends of the connecting member 28 are rotatably arranged relative to the fixing member 21 and the transmission member 24 .

[0038] It can be seen from the above description that providing a connecting member can play a certain limiting role on the movement of the transmission member.

[0039] Furthermore, the driving assembly 2 further includes a third rotating member 29 , and the transmission member 24 is rotatably arranged relative to the second driving member 23 via the third rotating member 29 .

[0040] Furthermore, it also includes a limit assembly 3 for limiting the return stroke of the first driving member 22, and the limit assembly 3 includes a first limit member 31 and a second limit member 32, the first limit member 31 is movably connected to the fixing member 21, the second limit member 32 is fixedly connected to the first driving member 22, and the first limit member 31 abuts against the second limit member 32.

[0041] It can be seen from the above description that the limit assembly can limit the return stroke of the first driving member.

[0042] Furthermore, the frame mechanism 100 is provided with a third limiting member 5 for limiting the movement range of the protection member 4 .

[0043] Another technical solution adopted by the present invention is:

[0044] A display screen comprises the display screen protection device.

[0045] Please refer to Figures 1 to 6 , Embodiment 1 of the present invention is:

[0046] A display screen includes a display screen housing and a display screen protection device, such as Figure 1 As shown, the display screen protection device includes a frame mechanism 100 and a protection mechanism 200. The shape of the frame mechanism 100 is adapted to the main body shape of the display screen and can protect the main body of the display screen. The protection mechanism 200 is arranged around the frame mechanism 100 and can protect the frame of the display screen.

[0047] like Figure 2 As shown, the protection mechanism 200 includes a control component 1, a drive component 2 and a protection member 4. The control component 1 includes a rocker 11 and a first rotating member 12. The rocker 11 is fixedly connected to the first rotating member 12. The shape of the protection member 4 is a long strip. Multiple drive components 2 can be set to simultaneously drive the protection member 4 to move.

[0048] like Figures 3 to 5As shown, the driving assembly 2 includes a fixing member 21, a first driving member 22, a second driving member 23 and a transmission member 24. The fixing member 21 is fixedly connected to the frame mechanism 100. One end of the first driving member 22 is rotatably arranged relative to the fixing member 21. In this embodiment, the fixing member 21 is rotatably sleeved on the first rotating member 12. The first driving member 22 is fixedly sleeved on the first rotating member 12. When the first rotating member 12 rotates, the first driving member 22 can be driven to rotate. Preferably, the number of the first driving members 22 is two, and the two first driving members 22 are respectively arranged on both sides of the fixing member 21. The driving assembly 2 also includes a first elastic recovery member 25, which is sleeved on the first rotating member 12, and the two ends of the first elastic recovery member 25 are respectively connected to the first driving member 22 and the fixing member 21. The number and elasticity of the first elastic recovery member 25 can be set as needed, and the first elastic recovery member 25 can be a torsion spring. In this embodiment, a limiter assembly 3 for limiting the return stroke of the first driving member 22 is also included, and the limiter assembly 3 includes a first limiter 31 and a second limiter 32. The first limiter 31 is movably connected to the fixing member 21, and the second limiter 32 is fixedly connected to the first driving member 22. The first limiter 31 abuts against the second limiter 32. The return stroke of the first driving member 22 can be limited by the cooperation of the first limiter 31 and the second limiter 32. When the first driving member 22 is driven by the elastic restoring force of the first elastic restoring member 25, the second limiter 32 will move, and the second limiter 32 will stop when it moves to the position of abutting against the first limiter 31. In this embodiment, the first limiter 31 also has a driving function. When the large end of the first limiter 31 is pressed in the direction close to the fixing member 21, the first limiter 31 will drive the second limiter 32 to move. Since the second limiter 32 is fixedly connected to the first driving member 22, the second limiter 32 will drive the first driving member 22 to rotate. Since a spring is sleeved on the first limit member 31, the first limit member 31 does not play a driving role when no artificial pressure is applied. The first drive member 22 is provided with a first drive surface 221 at the other end away from the control component 1, and the second drive member 23 is rotatably arranged relative to the fixed member 21. One end of the second drive member 23 is provided with a second drive surface 231 that matches the first drive surface 221. The first drive surface 221 and the second drive surface 231 can be in the form of a circular arc surface and a plane surface, or in the form of a gear surface and a gear surface. In this embodiment, the drive component 2 also includes a second rotating member 26 and a second elastic return member 27, and the second drive member 23 is rotatably arranged relative to the fixed member 21 through the second rotating member 26.The second elastic return member 27 is sleeved on the second rotating member 26, and the two ends of the second elastic return member 27 are respectively connected to the second driving member 23 and the fixed member 21. The number of the second driving members 23 can be two, and the two second driving members 23 are respectively arranged on both sides of the fixed member 21. Each second driving member 23 can be correspondingly provided with a second elastic return member 27, and the second elastic return member 27 can be a torsion spring. The transmission member 24 is arranged at the other end of the second driving member 23 away from the first driving member 22, and the protective member 4 is fixedly connected to the transmission member 24. In this embodiment, the driving assembly 2 further includes a connecting member 28 and a third rotating member 29, and the two ends of the connecting member 28 are rotatably arranged relative to the fixed member 21 and the transmission member 24. The transmission member 24 is rotatably arranged relative to the second driving member 23 through the third rotating member 29.

[0049] like Figure 6 As shown, the frame mechanism 100 is provided with a third limiting member 5 for limiting the movement range of the protection member 4 , and the protection member 4 stops moving when it moves to a position abutting against the third limiting member 5 .

[0050] The working principle of the display screen protection device of this embodiment is as follows: assuming that in the initial state, the display screen protection device is in a locked state, when the first rotating member 12 is driven to rotate by the rocker 11, the first rotating member 12 drives the first driving member 22 to rotate in a counterclockwise direction (refer to Figure 3 The first driving member 22 drives the second driving member 23 to rotate in the clockwise direction. The second driving member 23 drives the transmission member 24 to move when rotating. The transmission member 24 drives the protection member 4 to move away from the display screen. At this time, the display screen protection device is in the unlocked state. When the rocker 11 is released, the first driving member 22 and the second driving member 23 return to the predetermined unlocked state under the action of the elastic restoring force of the first elastic restoring member 25 and the second elastic restoring member 27.

[0051] Similarly, assuming that the display screen protection device is in a locked state, since the first limit member 31 also has a driving function, when the first limit member 31 is pressed, the first limit member 31 will drive the second limit member 32 to move, and the second limit member 32 will drive the first driving member 22 to rotate in the counterclockwise direction (refer to Figure 3 The first driving member 22 drives the second driving member 23 to rotate in the clockwise direction, and the second driving member 23 drives the transmission member 24 to move when rotating, and the transmission member 24 drives the protection member 4 to move away from the display screen, and the display screen protection device is in the unlocked state. Therefore, the first limiting member 31 has an unlocking function.

[0052] In summary, the display screen protection device and the display screen provided by the present invention can well protect the display screen during transportation and storage, and are simple to operate and convenient to install and disassemble.
