[0046] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means more than two, unless otherwise specifically defined.

[0047] As described in the background art, in the related art, both of the two components to be positioned have positioning surfaces; usually after the two components are positioned, the two positioning surfaces will also come into contact. However, during the positioning process of the two components, the two positioning surfaces are prone to collide due to the influence of the moving speed, which may cause damage to the components and shorten the service life of the components.

[0048] Refer to Figures 1 to 5, To solve the above problems, according to one aspect of the present application, embodiments of the present application provide a protection structure. The protection structure 100 is used to protect the first positioning surface 811 on the first component 800. The first component 800 is used to be positioned with the second component, and the second component has a second positioning surface; after the first component 800 and the second component are positioned, the first positioning surface 811 and the second positioning surface come into contact; the protection structure 100 is used to be installed on the first component 800, and the protection structure 100 has a protection position and an avoidance position; when the protection structure 100 is in the protection position, the protection structure 100 can cover the first positioning surface 811; when the protection structure 100 is in the avoidance position, the protection structure 100 can be located on one side of the first positioning surface 811, so that the first positioning surface 811 can come into contact with the second positioning surface; the first component 800 has a mounting surface 812 adjacent to the first positioning surface 811, and the protection structure 100 can move in a direction close to or away from the mounting surface 812, so that the protection structure 100 can switch between the protection position and the avoidance position.

[0049] In the embodiments of the present application, the structures of the first component 800 and the second component are the same, and both are display screen bodies that can form a display screen. The display screen body includes a lamp body 810, and both the first positioning surface 811 and the second positioning surface are the side surfaces on the lamp body 810; in other embodiments, the structures of the first component 800 and the second component may also be different, and at the same time, the first component 800 and the second component may also be other structural parts; after the first component 800 and the second component are positioned, the first positioning surface 811 and the second positioning surface are in fit. In addition, the mounting surface 812 is disposed opposite to the lamp surface on the lamp body 810. The protection structure 100 is installed on the first component 800. When the protection structure 100 is in the protection position, the protection structure 100 covers the first positioning surface 811; when the protection structure 100 is in the avoidance position, the protection structure 100 is located on one side of the first positioning surface 811 and exposes the first positioning surface 811. Before the first component 800 and the second component are ready to be positioned, drive the protection structure 100 close to the mounting surface 812 to switch the protection structure 100 from the avoidance position to the protection position; when the first component 800 and the second component are positioned, the protection structure 100 can be switched from the protection position to the avoidance position under the action of the pressing force applied by the second component. Of course, in other embodiments, the protection structure 100 can also be switched from the protection position to the avoidance position by driving the protection structure 100 away from the mounting surface 812. Figure 2 in which the protection structure 100 is in the protection position, Figure 3 in which the protection structure 100 is in the avoidance position.

[0050] When positioning the first component 800 and the second component, first drive the protection structure 100 close to the mounting surface 812 to switch the protection structure 100 from the avoidance position to the protection position. In this state, the presence of the protection structure 100 not only effectively prevents the second positioning surface from contacting the first positioning surface 811, thus avoiding direct collision between the second positioning surface and the first positioning surface 811, but also reduces the moving speed of the second component to zero after it contacts the protection structure 100, thereby slowing down the moving speed of the second component. Subsequently, drive the protection structure 100 away from the mounting surface 812 to switch the protection structure 100 from the protection position to the avoidance position. At this time, the first positioning surface 811 and the second positioning surface come into contact, and the first component 800 and the second component are positioned.

[0051] The provided protection structure 100 not only plays a buffering role, effectively slowing down the moving speed when the second component contacts the first component 800, thereby reducing the collision force exerted by the second positioning surface on the first positioning surface 811, reducing the risk of damage to the first positioning surface 811, extending the service life of the first positioning surface 811, but also helps to protect the first positioning surface 811 in the transportation and storage states, reducing the possibility of damage to the first positioning surface 811 caused by external collisions.

[0052] Referring to Figures 1 to 3 、 Figure 6 and Figure 7 According to another aspect of the present application, an embodiment of the present application further provides a protection mechanism. The protection mechanism includes a mounting member 200 and the above-mentioned protection structure 100. The mounting member 200 is used for mounting on the first component 800; the protection structure 100 is mounted on the mounting member 200 and can slide on the mounting member 200 in a direction close to or away from the mounting surface 812, and the movement direction of the protection structure 100 forms a first preset direction.

[0053] In the embodiment of the present application, the mounting member 200 is fixedly mounted on the first component 800 by mounting screws and is located on the side of the mounting surface 812 away from the first positioning surface 811. When positioning the first component 800 and the second component, first move the protection structure 100 along the first preset direction close to the mounting surface 812 until the protection structure 100 is in the protection position; after the moving speed of the second component is reduced to zero, move the protection structure 100 along the first preset direction away from the mounting surface 812 until the protection structure 100 is in the avoidance position; at this time, the first positioning surface 811 and the second positioning surface come into contact, and the first component 800 and the second component are positioned. The provided mounting member 200 serves to mount the protection structure 100. In addition, a groove is provided on the first component 800, and the mounting member 200 is mounted in the groove.

[0054] Referring toFigures 1 to 11 , in one embodiment, the surface of the protection structure 100 close to the mounting member 200 is the contact surface 110, and the surface of the mounting member 200 close to the protection structure 100 is the fixed surface 210; when the protection structure 100 is in the protection position, the contact surface 110 can cover the first positioning surface 811 and has a first spacing from the fixed surface 210; when the protection structure 100 is in the avoidance position, the contact surface 110 can be located on one side of the first positioning surface 811 and has a second spacing from the fixed surface 210, and the second spacing is less than the first spacing; the protection mechanism further includes a first reset member 300, the first reset member 300 is mounted on the mounting member 200, the first reset member 300 is drivingly connected to the protection structure 100, and can drive the protection structure 100 to switch from the avoidance position to the protection position.

[0055] In this embodiment, when the protection structure 100 is in the protection position, the contact surface 110 contacts the first positioning surface 811; when the protection structure 100 is in the avoidance position, the contact surface 110 contacts the fixed surface 210. The design that the second spacing is less than the first spacing effectively prevents the protection structure 100 in the avoidance position from interfering with the second component, ensuring the smooth progress of the positioning operation of the first component 800 and the second component. The first reset member 300 can be a reset spring or a cylinder. When the protection structure 100 is in the avoidance position, the first reset member 300 is in a compressed state and exerts a thrust on the protection structure 100 in the direction of the first positioning surface 811. The provided first reset member 300 helps to reset the protection structure 100 from the avoidance position to the protection position, so that the protection structure 100 effectively protects the first positioning surface 811. In addition, the number of the first reset members 300 is multiple, the multiple first reset members 300 are arranged at intervals, and are all drivingly connected to the protection structure 100, and can all drive the protection structure 100 to switch from the avoidance position to the protection position. In addition, the surface of the protection structure 100 close to the mounting surface 812 is adjacent to the contact surface 110, and a chamfer edge is provided on this surface to facilitate the protection structure 100 to switch from the protection position to the avoidance position.

[0056] Refer to Figures 6 to 11In one embodiment, the first resetting member 300 includes a connecting structure 310 and a resetting structure 320. The mounting member 200 is provided with a mounting groove 220. The connecting structure 310 is installed in the mounting groove 220 and can slide in the mounting groove 220 along the extension direction of the mounting groove 220; the extension direction of the mounting groove 220 is a second preset direction, and there is an angle between the second preset direction and the first preset direction; the connecting structure 310 is drivingly connected to the protective structure 100 and can push the protective structure 100 to switch from the avoidance position to the protection position; the resetting structure 320 is installed on the bottom of the mounting groove 220 and can push the connecting structure 310 to move toward the protective structure 100.

[0057] In this embodiment, the connection structure 310 can be a connection column or a connection block. The connection structure 310 can be fixedly connected to the protection structure 100 or can slide on the protection structure 100. The reset structure 320 can be a reset spring or a cylinder. The reset structure 320 is installed in the installation groove 220. The angle between the second preset direction and the first preset direction is an acute angle. The second preset direction can usually be parallel to the length direction of the first component 800. In other embodiments, the second preset direction can also be parallel to the width direction of the first component 800. The installation groove 220 not only plays the role of installing the reset structure 320, but also plays a limiting role, which prevents the reset structure 320 from shaking left and right on the mounting member 200, ensuring that the protection structure 100 can smoothly switch from the avoidance position to the protection position. In addition, the installation groove 220 also plays the role of reducing the volume of the protection mechanism.

[0058] Reference Figures 6 to 11, in one embodiment, a sliding through-hole 120 is provided on the contact surface 110, and a partial structure of the connection structure 310 is inserted into the sliding through-hole 120 and can slide relative to the protection structure 100 in the sliding through-hole 120 along a second preset direction; a limiting groove 130 is provided on the pore wall of the sliding through-hole 120, and the limiting groove 130 penetrates the contact surface 110; the connection structure 310 includes a first part 311, a second part 312 and a third part 313 connected in sequence, wherein the first part 311 can be inserted into the sliding through-hole 120; the second part 312 can be inserted into the limiting groove 130, and the groove wall of the limiting groove 130 can prevent the second part 312 from being inserted into the sliding through-hole 120 and can push the second part 312 to move outside the limiting groove 130; the third part 313 is located in the installation groove 220; the reset structure 320 is located between the surface of the second part 312 close to the third part 313 and the bottom of the installation groove 220; when the protection structure 100 is in the protection position, the first part 311 is inserted into the sliding through-hole 120 and the second part 312 is inserted into the limiting groove 130; when the protection structure 100 is in the avoidance position, the first part 311 is located in the sliding through-hole 120, the second part 312 is located outside the limiting groove 130, and the reset structure 320 applies a thrust to the second part 312 towards the protection structure 100.

[0059] In this embodiment, the extending direction of the sliding through-hole 120 has an acute angle with the first preset direction and has an acute angle with the second preset direction; the groove diameter of the limiting groove 130 is larger than the hole diameter of the sliding through-hole 120. The hole diameter of the first part 311 is less than or equal to the hole diameter of the sliding through-hole 120; the hole diameter of the second part 312 is larger than the hole diameter of the sliding through-hole 120 and less than or equal to the groove diameter of the limiting groove 130, and the hole diameter of the third part 313 is less than the hole diameter of the second part 312 and less than the groove diameter of the installation groove 220; the reset structure 320 is a reset spring, and the reset spring is sleeved on the third part 313. When the protection structure 100 is in the avoidance position, the second part 312 is located on the side of the protection structure 100 close to the installation part 200, and the reset structure 320 is in a compressed state. To facilitate the smooth sliding of the second part 312 from the limiting groove 130 to the outside of the limiting groove 130, the connection between the limiting groove 130 and the sliding through-hole 120 has a smooth transition; to reduce the groove depth of the installation groove 220, an opening for the third part 313 to extend outside the installation groove 220 is provided on the bottom of the installation groove 220.

[0060] When positioning the first component 800 and the second component, first move the protection structure 100 along a first preset direction towards the mounting surface 812 until the protection structure 100 is in the protection position; after the protection structure 100 is in the protection position, the first part 311 is inserted into the sliding through hole 120, and the second part 312 is inserted into the limiting groove 130; then move the protection structure 100 along the first preset direction away from the mounting surface 812. During this process, the second part 312 will move out of the limiting groove 130 under the action of the groove wall of the limiting groove 130, and the first part 311 will move in the direction towards the mounting groove 220 following the second part 312; after the protection structure 100 is in the avoidance position, the reset structure 320 will also apply a thrust towards the protection structure 100 to the second part 312. At this time, the first positioning surface 811 and the second surface come into contact, and the first component 800 and the second component are positioned.

[0061] When separating the first component 800 and the second component, directly move the second component in a direction away from the first component 800.

[0066] Referring to Figures 1 to 15 According to another aspect of the present application, an embodiment of the present application further provides a display screen, which includes a first display screen body, a second display screen body, a first positioning portion 600 and the above protection mechanism. The first display screen body has a first positioning surface 811, and the second display screen body has a second positioning surface; the first positioning portion 600 and the protection mechanism are both mounted on the first display screen body, and a first positioning groove 831 is provided on the second display screen body; after the first display screen body and the second display screen body are positioned, the first positioning portion 600 is inserted into the first positioning groove 831, and the first positioning surface 811 and the second positioning surface are in contact; when the first display screen body and the second display screen body are positioned, the protection structure 100 can be switched from the protection position to the avoidance position under the action of the pressing force applied by the second display screen body; the first display screen body forms a first component 800, and the second display screen body forms a second component.

[0067] In the embodiments of the present application, the display screen is usually an LED display screen. The full English name of LED is Light Emitting Diode, and the Chinese name is light emitting diode; in other embodiments, the display screen can also be other types of display screens. The structures of the first display body and the second display body are the same. In other embodiments, the structures of the first display body and the second display body can also be different; the first display body includes a lamp body 810, a first mounting body 820, and a second mounting body 830. Among them, the first positioning surface 811 is the side surface of the lamp body 810, and the mounting surface 812 is the surface of the lamp body 810 that is arranged opposite to the lamp surface; the protection mechanism is mounted on the first mounting body 820, and the first mounting body 820 is mounted on the mounting surface 812; the first positioning portion 600 can be a positioning post, the first positioning portion 600 is fixedly mounted on the second mounting body 830, and the second mounting body 830 is mounted on the mounting surface 812. In addition, after the first display body and the second display body are positioned, the first positioning surface 811 and the second positioning surface are in contact, and at the same time when the first display body and the second display body are positioned, the pressing force applied by the second display body is the gravity of the second display body.

[0068] When the first display body and the second display body are positioned, first place the protection structure 100 in the protection position. In this state, the existence of the protection structure 100 not only prevents the second positioning surface from contacting the first positioning surface 811, thus avoiding direct collision between the second positioning surface and the first positioning surface 811, but also reduces the moving speed of the second display body to zero after it contacts the protection structure 100, thereby slowing down the moving speed of the second display body; then use the second display body to apply a pressing force to the protection structure 100, and the protection structure 100 switches from the protection position to the avoidance position under the action of the pressing force applied by the second display body. At this time, the first positioning portion 600 is inserted into the first positioning groove 831, and at the same time the first positioning surface 811 and the second positioning surface are in contact, and the first component 800 and the second component are positioned. In addition, the first display body has two relatively arranged first positioning surfaces 811, and four protection mechanisms are mounted on the first display body. The first display body includes two relatively arranged first mounting bodies 820. Among them, two of the four protection mechanisms are correspondingly arranged with one of the two first positioning surfaces 811 and are both mounted on one of the two first mounting bodies 820, and the other two protection mechanisms are correspondingly arranged with the other first positioning surface 811 and are both mounted on the other first mounting body 820; at the same time, the four protection mechanisms are respectively arranged corresponding to the four corners of the first display body. The second mounting body 830 is provided with a first positioning groove 831, and the first positioning groove 831 is arranged opposite to the first positioning portion 600.

[0069] Reference Figure 1 、 Figure 5 、 Figure 12 and Figure 13 In one embodiment, the first positioning portion 600 includes a positioning body 610 and a positioning head 620. The positioning head 620 is mounted on the positioning body 610 and is located on a side of the positioning body 610 away from the first positioning surface 811. The positioning body 610 covers the positioning head 620. The first positioning groove 831 includes a first positioning groove section 831a and a second positioning groove section 831b arranged in sequence along a third preset direction. The second positioning groove section 831b communicates with the first positioning groove section 831a. The positioning head 620 can penetrate into the first positioning groove section 831a and can slide from the first positioning groove section 831a to the second positioning groove section 831b along the third preset direction. The groove wall of the first positioning groove section 831a can block the positioning body 610 from penetrating into the first positioning groove section 831a, and the positioning body 610 can penetrate into the second positioning groove section 831b. When the positioning head 620 slides from the first positioning groove section 831a to the second positioning groove section 831b, the protection structure 100 switches from the protection position to the avoidance position. After the first display body and the second display body are positioned, the first positioning portion 600 penetrates into the second positioning groove section 831b.

[0070] In this embodiment, the positioning body 610 is a positioning cylinder, the positioning head 620 is a conical head, the maximum diameter of the positioning head 620 is less than or equal to the diameter of the positioning body 610, and the positioning head 620 is fixedly connected to the positioning body 610. There is an acute angle between the third preset direction and the first preset direction, and there is an included angle with the second preset direction. The third preset direction is generally parallel to the width direction of the first display body. In other embodiments, the third preset direction can also be parallel to the length direction of the first display body. A part of the structure of the positioning head 620 can penetrate into the first positioning groove section 831a. The diameter of the positioning body 610 is larger than the diameter of the first positioning groove section 831a and smaller than the diameter of the second positioning groove section 831b. The positioning head 620 and the first positioning groove section 831a used in cooperation in this application not only play a role in rough positioning, which helps the first display body and the second display body to be quickly positioned, but also helps the second display body to apply a pressing force to the protection structure 100, so that the protection structure 100 can switch from the protection position to the avoidance position more smoothly.

[0071] In one embodiment, a protection mechanism is installed on the second display body. When the first display body and the second display body are positioned, the two protection structures 100 can contact and can switch from the protection position to the avoidance position simultaneously.

[0072] The protection structure 100 on the second display body not only plays a buffering role, which helps to slow down the moving speed when the second display body contacts the first display body, thereby reducing the impact force exerted by the protection structure 100 on the first display body on the second positioning surface, further reducing the risk of damage to the second positioning surface and extending the service life of the second positioning surface. At the same time, it also helps to protect the second positioning surface in the transportation and storage states and reduces the possibility of damage to the second positioning surface caused by external collisions. In addition, the second display body has two oppositely arranged second positioning surfaces, and four protection mechanisms are installed on the second display body. Among them, two of the four protection mechanisms are correspondingly arranged with one of the two second positioning surfaces, and the other two protection mechanisms are correspondingly arranged with the other second positioning surface. At the same time, the four protection mechanisms are respectively arranged corresponding to the four corners of the second display body.

The third display body is located on one side of the first display body. The first display body has a third positioning surface 813, and the third display body has a fourth positioning surface. The third positioning surface 813 is adjacent to the first positioning surface 811. The second positioning portion 700 is installed on the third positioning surface 813 and can be compressed when blocked by an external force. A second positioning groove 821 is provided on the fourth positioning surface. After the third display body and the second display body are positioned, the second positioning portion 700 is inserted into the second positioning groove 821, and the third positioning surface 813 contacts the fourth positioning surface.

[0074] In this embodiment, the structure of the third display body is the same as that of the first display body. In other embodiments, the structure of the third display body may also be different from that of the first display body. The second positioning portion 700 can be a spring or a cylinder. The third positioning surface 813 is the side surface of the lamp body 810, which is adjacent to the lamp surface, the first positioning surface 811, and the mounting surface 812. The provided second positioning portion 700 not only helps to position the third display body and the second display body, but also avoids the collision between the third positioning surface 813 and the fourth positioning surface, playing a role in preventing bumps.

[0075] Refer to Figure 1 、 Figure 4 and Figures 14 to 17, in one embodiment, the second positioning portion 700 includes a mounting block 710, a positioning pin 720, and a return spring 730. Among them, the first display body has a mounting space, and an exposed port communicating with the mounting space is provided on the third positioning surface 813; the mounting block 710 is mounted in the mounting space, and a mounting groove is provided on the mounting block 710, and the positioning pin 720 is mounted in the mounting groove; the positioning pin 720 includes a positioning section 721, a limiting section 722, and a mounting section 723 connected in sequence. One end of the positioning section 721 away from the limiting section 722 extends outside the mounting space through the exposed port, the limiting section 722 is located in the mounting space and can slide in the mounting groove, and the exposed port can prevent the limiting section 722 from extending outside the mounting space; the mounting section 723 is located in the mounting groove; the return spring 730 is sleeved on the mounting section 723 and is located between the surface of the limiting section 722 close to the connecting section and the bottom of the mounting groove, and an opening for the mounting section 723 to extend outside the mounting groove is provided on the bottom of the mounting groove.

[0076] In this embodiment, the mounting space is provided on the first mounting body 820. The diameter of the positioning section 721 is smaller than the diameter of the exposed port; the diameter of the limiting section 722 is larger than the diameter of the exposed port and smaller than the diameter of the mounting through hole; the diameter of the connecting section is smaller than the diameter of the limiting section 722 and larger than the diameter of the opening. In addition, the extending direction of the second positioning groove 821 is parallel to the second preset direction, and at the same time, the second positioning portion 700 can slide in the second positioning groove 821 along the second preset direction to accurately position the first display body and the third display body; the second positioning portion 700 is mounted on one of the two first mounting bodies 820, and the second positioning groove 821 is provided on the other first mounting body 820.

[0077] In summary, implementing the protection structure, protection mechanism, and display screen provided in this embodiment has at least the following beneficial technical effects: When positioning the first component 800 and the second component, first drive the protection structure 100 close to the mounting surface 812 to switch the protection structure 100 from the avoidance position to the protection position. In this state, the presence of the protection structure 100 not only effectively prevents the second positioning surface from contacting the first positioning surface 811, thus avoiding direct collision between the second positioning surface and the first positioning surface 811, but also reduces the moving speed of the second component to zero after contacting the protection structure 100, thereby slowing down the moving speed of the second component; Subsequently, drive the protection structure 100 away from the mounting surface 812 to switch the protection structure 100 from the protection position to the avoidance position. At this time, the first positioning surface 811 and the second positioning surface come into contact, and the first component 800 and the second component are positioned. The provided protection structure 100 not only plays a buffering role, effectively slowing down the moving speed when the second component contacts the first component 800, thereby reducing the collision force exerted by the second positioning surface on the first positioning surface 811, reducing the risk of damage to the first positioning surface 811, extending the service life of the first positioning surface 811, but also helps to protect the first positioning surface 811 in the transportation and storage states, reducing the possibility of damage to the first positioning surface 811 caused by external collisions.
