[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0048] First embodiment

[0049] AsFigure 1 , Figure 2 and Figure 5 As shown in ,

[0050] , an embodiment of the present application provides a protection mechanism 100, including:

[0050] A limit component 10, including two limit members 11 arranged at intervals in a first direction, and the limit members 11 are installed on a component 40 to be protected;

[0051] An active power component 20, including a driving member 21 and an active power member 22. The driving member 21 is arranged on the component 40 to be protected and is located between the two limit members 11. The active power member 22 includes a power part 221 and two end connection parts 222 connected to each other. The power part 221 is connected to the driving member 21, and the two end connection parts 222 penetrate through the two limit members 11 along the first direction respectively;

[0052] A driven buffer component 30, including a buffer member 31. The buffer member 31 penetrates through the two limit members 11 along the first direction, and two ends of the buffer member 31 are connected to the two end connection parts 222 of the active power member 22;

[0053] In a natural state, the buffer member 31 is in a straightened state, and there is a distance between at least one end of the buffer member 31 and the adjacent limit member 11;

[0054] In a protection state, the driving member 21 drives the two end connection parts 222 of the active power member 22 to move towards each other. Under the pulling force of the active power member 22, the two ends of the buffer member 31 move towards each other. The buffer member 31 between the two limit members 11 bulges towards the side away from the component 40 to be protected to form a bending part, and the height of the bending part is greater than the height of the limit member 11.

[0055] When it is necessary to protect the component 40 to be protected, the protection mechanism 100 is in a protection state. In this state, the driving member 21 drives the two ends of the active power member 22 to move, so that the two ends of the buffer member 31 connected to the two ends of the active power member 22 move towards each other. Under the pulling force and its own buffering effect, the buffer member 31 bulges outwards to form a bending deformation, and the height of the bending part of the buffer member 31 is higher than the height of the limit member 11. When it falls to the ground, the bending part of the buffer member 31 can touch the ground first, thus playing a buffering role, and further playing a role in protecting the component 40 to be protected and preventing the component 40 to be protected from being bruised.

[0056] Refer to Figure 2, Exemplarily, the buffer member 31 can be any component that can achieve buffer deformation under tensile force, and it also has a certain elastic force by itself, so as to ensure the protection effect on the component 40 to be protected. In this application, the buffer member 31 is a buffer spring strip, and the effect of the buffer spring strip can be similar to that of a tape measure, that is, it can maintain a straight state in the natural state, and can be bent and deformed after being stressed, and it also has a certain elasticity.

[0057] Referring to Figure 1 and Figure 4 , Similarly, the active power component 20 can be any driving member 21 that can exert a tensile force on the end of the buffer member 31. The active power member 22 can be made of a hard material, such as a pull rod or a telescopic rod, etc., which can achieve the movement of the end, or the active power member 22 can also be made of a flexible material, such as a wire or a rope, etc., which can achieve winding and retracting. In this application, the active power member 22 is a pull rope, and the pull rope extends in the natural state; in the protection state, the pull rope winds and contracts to exert a tensile force on the buffer member 31, and at the same time, it is also convenient to store the retracted part.

[0058] Combined with Figure 2 , Of course, the driving member 21 can also be any component that can achieve power drive in the prior art, and the driving member 21 can also select a component adapted to it according to the difference of the active power member 22. For example, when the active power member 22 is made of a hard material, the driving member 21 can be an electric push rod or a cylinder, etc., and the contraction of its piston rod drives the movement of the end of the active power member 22 to further achieve the drive of the buffer member 31. When the active power member 22 is made of a flexible material, the driving member 21 can be a motor, and the output shaft of the motor is connected to the flexible material, and the flexible material is wound by the rotation of the output shaft, so as to achieve the pulling of the end of the active power member 22.

[0059] Referring to Figure 1 , Figure 4 and Figure 5, in some embodiments, the driving member 21 is connected to the driving force member 22 through a rotating shaft 23. A winding portion 231 is provided on the rotating shaft 23, and the power portion 221 of the driving force member 22 is fixedly arranged on the winding portion 231. The driving member 21 is used to drive the rotation of the rotating shaft 23. Exemplarily, the driving member 21 is a motor, and the driving force member 22 is a pulling rope; the motor is detachably arranged on the member to be protected 40 through bolts, and the output shaft of the motor can be coaxially fixed to the rotating shaft 23 through a coupling; alternatively, the output shaft of the motor is rotationally connected through a transmission assembly, so that the rotation of the output shaft of the motor drives the rotation of the rotating shaft 23. The part of the pulling rope used for connecting with the rotating shaft 23 is the power portion 221 of the driving force member 22. The power portion 221 is wound around the rotating shaft 23, and the two ends of the pulling rope are the end connection portions 222 of the driving force member 22. The two end connection portions 222 respectively penetrate through the two limiting members 11; the power portion 221 is wound and fixed on the winding portion 231 of the rotating shaft 23. During the rotation of the rotating shaft 23, the pulling rope can be stably wound on the rotating shaft 23 to avoid the sliding of the pulling rope and affect the wire winding effect of the pulling rope.

[0060] Referring to Figure 4 and Figure 5 , optionally, there are two winding portions 231. The two ends of the power portion 221 are respectively fixed through the two winding portions 231 and are respectively connected to the two end connection portions 222; the two winding portions 231 are located at the same axial height of the rotating shaft 23. By providing two winding portions 231, both ends of the power portion 221 are fixed, further ensuring the fixing effect of the rotating shaft 23 on the driving force member 22; in addition, by setting the same height of the two winding portions 231, the wire winding acting forces of the two winding portions 231 on the two end connection portions 222 are the same, so as to ensure the same pulling forces on both ends of the buffer member 31 and ensure the force receiving effect and bending effect of the buffer member 31.

[0061] Of course, there is a height difference between the two winding portions 231 in the axial direction of the rotating shaft 23, that is, the two winding portions 231 are respectively located at different heights of the rotating shaft 23.

[0062] Referring to Figure 1 and Figure 2 , in some embodiments, the protection mechanism 100 further includes a connection block 32. The end connection portion 222 of the driving force member 22 is connected to the buffer member 31 through the connection block 32. Through the arrangement of the connection block 32, the end of the buffer member 31 and the end of the driving force member 22 are stably connected. At the same time, it can also ensure that the end of the buffer member 31 and the end of the driving force member 22 both penetrate through the limiting member 11, ensuring the bending effect of the buffer member 31 after being subjected to a pulling force.

[0063] In some embodiments, in the natural state, the buffer member 31 is in a straightened state, and there is a spacing between at least one end of the buffer member 31 and the adjacent limiting member 11. This spacing is the bending deformation amount of the buffer member 31 in the protection state. In the protection state, the two ends of the active force member 22 are pulled inward until the ends of the two end connectors of the active force member 22 abut against the adjacent limiting member 11, driving the two ends of the buffer member 31 to also move to abut against the adjacent limiting member 11, and the buffer member 31 located between the two limiting members 11 is forced to bulge outward to form a bending portion.

[0064] Optionally, the driving member 21 is disposed at the middle position between the two limiting members 11. In the natural state, the spacing between the two ends of the buffer member 31 and the adjacent limiting members 11 is the same; the acting forces of the driving member 21 on the two end connection portions 222 of the active force member 22 are the same. Under the pulling force of the active force member 22, the pulling forces on the two ends of the buffer member 31 are the same, and they move inward simultaneously, enabling the buffer member 31 to move stably and forming a bending portion at the middle position of the buffer member 31.

[0065] Of course, according to the different lengths of the member to be protected 40, the limiting assembly 10 can be correspondingly provided with one group, two groups or multiple groups. When the limiting assembly 10 is provided with two groups or multiple groups, in the protection state, the buffer member 31 can form (2N - 1) bending portions, where N is the number of groups of the buffer member 31. By means of multiple bending portions, the buffering effect is increased, and further the protection effect of the protection mechanism 100 on the member to be protected 40 is ensured.

[0066] Second Embodiment

[0067] Referring to Figure 6 As shown, the embodiment of the present application further provides a display device, including:

[0068] A bottom plate 300, the bottom plate 300 includes a display area 301 and a border area;

[0069] A display panel 200, disposed on the bottom plate 300 and corresponding to the display area 301;

[0070] A backlight module 400, disposed on the bottom plate 300 and on the backlight side of the display panel 200;

[0071] The protection mechanism 100 as described in the first embodiment, and the limiting member 11 of the protection mechanism 100 is disposed on the border area of the bottom plate 300.

[0072] When the display device is in normal use, the protection mechanism 100 is in a natural state; when the display device is knocked over, the buffer member 31 of the protection mechanism 100 bends to form a convex curved portion, and the convex curved portion touches the ground first to achieve a buffering effect, thereby protecting the display panel 200 and ensuring the display effect of the display device.

[0073] Combined with Figure 12 , in some embodiments, a front frame 500 is provided on the border area of the bottom plate 300. The front frame 500 is provided with an avoidance hole penetrating in the thickness direction of the display panel 200, and the avoidance hole corresponds to the curved portion of the buffer member 31 of the protection mechanism 100. In the protection state, the curved portion protrudes from the avoidance hole. The setting of the front frame 500 can cover the protection mechanism 100 and ensure the overall aesthetics of the display device. At the same time, through the opening of the avoidance hole, when the protection mechanism 100 is in the protection state, the curved portion formed by the bending deformation of the buffer member 31 protruding outward can protrude from the avoidance hole, and the curved portion touches the ground first to ensure the buffering effect of the buffer member 31.

[0074] Referring to Figure 6 and Figure 12 , specifically, the border area includes a plurality of display borders connected to each other. The plurality of display borders are arranged around the outer periphery of the display panel 200, and the protection mechanism 100 is provided on at least one of the display borders. The overall structure formed by the connection of the plurality of display borders is arranged in a cuboid ring structure. For the convenience of description, the plurality of display borders include an upper border 302, a lower border 303, a left border 304, and a right border 305. The upper border 302 is located above the display panel 200, the lower border 303 is located below the display panel 200, the left border 304 is located on the left side of the display panel 200, and the right border 305 is located on the right side of the display panel 200.

[0075] Optionally, the protection mechanism 100 is provided on at least one of the display borders, including one, two, three, or four protection mechanisms 100.

[0076] In an optional embodiment, four protection mechanisms 100 are provided, and the four protection mechanisms 100 are respectively provided on the four display borders.

[0077] Referring to Figure 7 and Figure 12 , in an optional embodiment, three protection mechanisms 100 are provided, and the three protection mechanisms 100 are respectively provided on the upper border 302, the left border 304, and the right border 305.

[0078] Referring to Figures 9 - 12In an optional embodiment, two protective mechanisms 100 are provided, and the two protective mechanisms 100 are respectively located on the upper frame 302 and the lower frame 303; or the two protective mechanisms 100 are respectively located on the left frame 304 and the right frame 305.

[0079] Reference Figure 8 In an optional embodiment, the protection mechanism 100 is provided with one, and the protection mechanism 100 is provided on the upper frame 302 .

[0080] Reference Figures 11 - 13 In some embodiments, the backlight module 400 includes an edge-entry backlight module 400 or an edge-entry backlight module 400. A detection member 306 is provided on the bottom plate 300, and the backlight module 400 includes a controller 401. The detection member 306 and the driving member 21 of the protection mechanism 100 are electrically connected to the controller 401. The detection member 306 is used to detect the state of the display device, so as to judge whether the protection mechanism 100 should be in a natural state or a protective state, so that the buffer member 31 is deformed by force in time to avoid damage to the display panel 200. Specifically, the detection member 306 includes a sensor that can detect the current state, such as an acceleration sensor or an angular velocity sensor. The acceleration of the display panel 200 is detected by the detection member 306, and the detection member 306 is composed of a mass block, a damper, an elastic element, a sensitive element, and an adaptive circuit. During the acceleration process, the acceleration value is obtained by measuring the inertial force on the mass block using Newton's second law. The optional acceleration sensors include capacitive, inductive, strain, piezoresistive, piezoelectric, etc. The acceleration change is used to determine the signal that the display device is about to fall, and then transmit the signal to the driving member 21, which drives the main force member 22 to move, driving the buffer member 31 to move synchronously, and the curved portion bulges outward to contact the ground, playing a buffering role to prevent the display panel 200 from being damaged.

[0081] Optionally, the detection member 306 is disposed on the bottom plate 300, and the detection member 306 is located above the display panel 200. By arranging the detection member 306 above the display panel 200, when the display device is knocked over, the top of the display device will be displaced first, so that the detection member 306 can detect the fall signal first and transmit the signal in time, thereby ensuring the braking efficiency of the protection mechanism 100.
