[0042] The following will describe in detail some embodiments of the present application with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0043] As Figures 1 to 12 shown, according to the first aspect of the present application, the present application provides a protection structure 100 for use in a display screen. The display screen includes a cabinet frame 200 and a display module mounted on the cabinet frame 200. Among them, the protection structure 100 includes a protection piece 20, an elastic member 30, and a mounting seat 10 for mounting on the cabinet frame 200. The protection piece 20 is movably connected to the mounting seat 10. The elastic member 30 always maintains an elastic force in the direction of the protection piece 20 to drive the protection piece 20 to move away from the mounting seat 10, so that the protection piece 20 can be at the highest point position of the mounting seat 10 in the natural state, thereby better protecting the display module on the cabinet frame 200 and preventing the corners of the display module from being knocked. When there is an external force, the protection piece 20 can slide to the lowest point of the mounting seat 10 to release the protection of the display module on the cabinet frame 200, so that the two cabinet frames 200 can be spliced together well.
[0044] It should be noted that the natural state means that when the protection piece 20 is not affected by an external force, the protection piece 20 is at the highest point position of the mounting seat 10 under the action of the elastic member 30, preventing the corners of the display module from being knocked. When the protection piece 20 is in a stressed state, the protection piece 20 can slide to the lowest point of the mounting seat 10 to release the protection of the display module on the cabinet frame 200.
[0045] In an alternative embodiment, the mounting base 10 is provided with a track groove 11 inclined in the height direction. The protective piece 20 is slidably mounted in the track groove 11. Both ends of the elastic member 30 are respectively abutted against the mounting base 10 and the protective piece 20. The elastic member 30 always maintains an elastic force in the direction of the protective piece 20 to drive the protective piece 20 to move away from the mounting base 10, so that the protective piece 20 can be at the highest point position of the mounting base 10 in the natural state, thereby better protecting the display module on the cabinet frame 200 and preventing the corners of the display module from being knocked. When an external force acts, the protective piece 20 can smoothly slide to the lowest point of the mounting base 10 along the track groove 11 to release the protection of the display module on the cabinet frame 200.
[0046] Exemplarily, since the display screen is developing more and more towards the high-end direction, the display screen products in the market tend to be light and thin. Especially in the rental screen market, for applications in different places, it is necessary to continuously disassemble and transport. During the disassembly and transportation process, the display screen is very easy to be knocked. For display screen products, the most easily damaged parts are the corners of the display module, resulting in dead pixels on the entire screen. Therefore, in this application, through the track groove 11 inclined in the height direction, the protective piece 20 can be at the highest point position of the mounting base 10 in the natural state; when an external force acts, the protective piece 20 can smoothly slide to the lowest point of the mounting base 10 along the track groove 11. It can not only better protect the display module in the natural state, but also release the protection of the display module when under force, enabling the two cabinet frames 200 to be better spliced together, with a simple structure, convenient processing and low manufacturing cost.
[0047] In an alternative embodiment, the protective piece 20 is provided with a connecting shaft 21. The connecting shaft 21 is slidably mounted in the track groove 11. The elastic member 30 abuts against the connecting shaft 21 to drive the protective piece 20 to move away from the mounting base 10. That is, when the protective piece 20 is in the natural state, the connecting shaft 21 is at the highest point of the track groove 11 under the action of the elastic member 30, so that the protective piece 20 can extend out of the cabinet frame 200 and be located outside the display module, thereby better protecting the display module; when the protective piece 20 is in the stressed state, the protective piece 20 drives the connecting shaft 21 to slide to the lowest point of the track groove 11 under the extrusion of the external force, so that the protective piece 20 can retract below the display module to release the protection of the display module, so that the two cabinet frames 200 can be closely fitted together when spliced.
[0048] It should be noted that the connecting shaft 21 can be an integral structure with the protective piece 20, or the connecting shaft 21 can be a split structure with the protective piece 20 and then fixed together by an assembly method.
[0049] In an alternative embodiment, the protection piece 20 includes a connecting boss 20b and a protection plate 20a for receiving an external force. The connecting boss 20b is vertically connected to the inner side of the protection plate 20a. The connecting shaft 21 is inserted through the connecting boss 20b, and the connecting shaft 21 is slidably connected to the track groove 11. So that when the protection plate 20a is in a natural state, the connecting shaft 21 can be at the highest point of the track groove 11 under the action of the elastic member 30; when the protection plate 20a is in a stressed state, the protection plate 20a drives the connecting shaft 21 to slide to the lowest point of the track groove 11 under the extrusion of the external force, so that the protection piece 20 can be retracted under the display module. It has a simple structure, is convenient to process, and has a low manufacturing cost.
[0050] Exemplarily, a shaft hole 201b is provided on the connecting boss 20b. One end of the connecting shaft 21 is slidably connected to the track groove 11 on one side of the connecting boss 20b, and the other end of the connecting shaft 21 passes through the shaft hole 201b and is slidably connected to the track groove 11 on the other side of the connecting boss 20b, so that the protection piece 20 can be stably mounted on the mounting seat 10 through the connecting boss 20b and can move along the guiding direction of the track groove 11.
[0051] In an alternative embodiment, the connecting shaft 21 includes a shaft body 211 and a snap spring 212. The shaft body 211 is inserted through the shaft hole 201b and the track groove 11, and the snap spring 212 is snap-connected to one end or both ends of the shaft body 211 to limit the connecting shaft 21 in the track groove 11.
[0052] In an alternative embodiment, the uppermost end of the protection plate 20a is chamfered with a bevel so as to be better received in the box frame 200.
[0053] In an alternative embodiment, a guiding platform 23 is provided on the side of the connecting boss 20b facing away from the protection plate 20a. A guiding groove 12 is formed on the mounting seat 10. The guiding platform 23 is slidably mounted in the guiding groove 12 to ensure the stability of the sliding of the protection piece 20 relative to the mounting seat 10, so that the connecting shaft 21 can reciprocally slide between the lowest point and the highest point of the track groove 11.
[0054] In an alternative embodiment, 22 connecting ribs are provided on the inner side of the protection plate 20a. The 22 connecting ribs extend along the width direction of the protection plate 20a. At least part of the structure of the connecting boss 20b is connected to the 22 connecting ribs, which is used to enhance the connection strength between the connecting boss 20b and the protection plate 20a and the strength of the protection plate 20a itself; at the same time, the 22 connecting ribs can also contact the outer side wall of the box frame 200 when the connecting shaft 21 is at the highest point of the track groove 11, which can play a buffering role.
[0055] In an alternative embodiment, the cross-section of the 22 connecting ribs gradually decreases in a direction away from the protection plate 20a, so as to improve the connection strength between the 22 connecting ribs and the protection plate 20a, and at the same time, the contact area between the 22 connecting ribs and the outer wall of the box frame 200 can also be reduced. Wherein, the free end of the 22 connecting ribs is of an arc surface structure.
[0056] In an alternative embodiment, the mounting seat 10 includes a fixing portion 10a for mounting to the box frame 200 and two spaced-apart extending portions 10b. The two extending portions 10b extend in a direction away from the fixing portion 10a from one side of the fixing portion 10a, and the track groove 11 is formed on the extending portion 10b.
[0057] In an alternative embodiment, a fixing end 13 is provided on the fixing portion 10a, a mounting groove 203 is provided on the box frame 200, and a fixing post is provided in the mounting groove 203. The fixing portion 10a is mounted on the fixing post through the fixing end 13.
[0058] In an alternative embodiment, a guiding inclined surface 14 is formed at one end of the extending portion 10b away from the fixing portion 10a. The inclination angle of the guiding inclined surface 14 is the same as the inclination angle of the track groove 11, so that the 22 connecting ribs can reciprocally slide between the lowest point and the highest point of the track groove 11 along the guiding inclined surface 14, which can play a role in avoiding collision, and prevent the 22 connecting ribs from colliding with the mounting seat 10 during movement.
[0059] In an alternative embodiment, an inclined surface groove 15 is provided on the extending portion 10b. The inclination angle of the inclined surface groove 15 is the same as the inclination angle of the track groove 11. One end of the elastic member 30 is received in the inclined surface groove 15, and the other end of the elastic member 30 abuts against the connecting shaft 21 of the protection piece 20, so that the direction of the force exerted on the connecting shaft 21 by the elastic member 30 is the same as the sliding direction.
[0060] In an alternative embodiment, the protection structure 100 further includes a first positioning post 201. The first positioning post 201 is provided at the lower end of the protection piece 20 and is used to limit the movement of the protection piece 20, so that the protection piece 20 can remain stationary when the first positioning post 201 is not stressed, that is, the protection piece 20 can only move downward to release the protection of the display module when two adjacent box frames 200 are spliced with each other or both the first positioning post 201 and the protection piece 20 are stressed.
[0061] It should be noted that the first positioning post 201 can be a part of the box frame 200, or the first positioning post 201 can also be a part of the protection structure 100. Its main function is to further limit the movement of the protection piece 20 and play a role in positioning. This application does not impose any restrictions.
[0062] In an alternative embodiment, the first positioning post 201 has an abutting end 2011 and a limiting end 2012. The limiting end 2012 is used to cooperate with the protection piece 20 to limit the movement of the protection piece 20 in a direction away from the display module. The abutting end 2011 is used to drive the limiting end 2012 to release the limitation on the protection piece 20 when two box frames 200 are spliced.
[0063] Exemplarily, the limiting end 2012 is arranged below the protection piece 20 and is used to prevent the protection piece 20 from moving downward, so that the protection piece 20 is not easily moved when protecting the box frame 200. The protection piece 20 can move downward when the box frames 200 are spliced. Wherein, a second positioning post 202 abutting against the abutting end 2011 can be arranged on the box frame 200. When two adjacent box frames 200 are spliced, the second positioning post 202 applies a force to the abutting end 2011 to make the limiting end 2012 contact and limit the protection piece 20, and then the two protection pieces 20 are mutually extruded, so that the protection piece 20 moves downward to release the protection of the display module.
[0064] As Figures 1 to 12 shown, according to the second aspect of the present application, the present application provides a display screen, including a display module, a box frame 200, and the above protection structure 100. The display module is installed on the box frame 200, and the protection structure 100 is installed at the corners of the box frame 200 for protecting the corners of the display module.
[0065] In an alternative embodiment, the box frame 200 includes a first positioning post 201 and a second positioning post 202. The first positioning post 201 is movably installed on the box frame 200, and the second positioning post 202 is arranged on one side of the first positioning post 201. Wherein, the first positioning post 201 is arranged at the lower end of the protection piece 20 and is used to limit the movement of the protection piece 20.
[0066] In an alternative embodiment, the box frame 200 includes a first frame and a second frame that can be spliced with each other. The first positioning post 201 and the second positioning post 202 on the first frame are arranged in a staggered manner with the first positioning post 201 and the second positioning post 202 on the second frame, so that the second positioning post 202 on the first frame can drive the first positioning post 201 on the second frame to release the restriction on the protection piece 20, and the second positioning post 202 on the second frame can drive the first positioning post 201 on the first frame to release the restriction on the protection piece 20.
[0067] In an alternative embodiment, the cabinet frame 200 is provided with a mounting groove 203 and a movable hole 205 communicating with the mounting groove 203. The first positioning post 201 has an abutting end 2011 and a limiting end 2012. The limiting end 2012 is used to cooperate with the protection piece 20 to limit the protection piece 20 from moving away from the display module, preventing the protection piece 20 from retracting. The abutting end 2011 is used to drive the limiting end 2012 to release the limitation on the protection piece 20 when two cabinet frames 200 are spliced.
[0068] In an alternative embodiment, avoiding grooves 204 are provided on the outer side walls of the cabinet frame 200. When the connecting shaft 21 moves to the lowest point of the track groove 11, the 22 connecting ribs can be accommodated in the avoiding grooves 204, so that the outer side walls of the frame structure can be kept flat, facilitating good splicing of two frame structures.
[0069] In an alternative embodiment, the cabinet frame 200 includes a first part, a second part, a third part and an adjusting mechanism 300. The second part and the third part are rotatably mounted on both sides of the first part through the adjusting mechanism 300, so that the angle formed between the second part and the third part and the first part can be adjusted through the adjusting mechanism 300, forming a mounting surface with a corresponding arc or angle on the cabinet frame 200. Then, the display module can be mounted to form a curved or flat display screen. The operation is simple and fast, and it can be applied to different application scenarios.
