[0051] In the present application, when the protection mechanism is in the protection position, the limiting piece 300 blocks the protection piece 200 from sliding on the mounting piece 100 by contacting the protection piece 200, so that the protection piece 200 can stably stay on the side away from the back surface 720 of the surface to be protected 710; in this case, the protection piece 200 will not slide due to small external force, but can effectively block the damage to the surface to be protected 710 caused by external collision, scratching, etc., providing stable and reliable protection for the surface to be protected 710, thereby prolonging the service life of the surface to be protected 710 and the protection piece 700.

[0052] In addition, during the process of switching the protection mechanism from the protection position to the avoidance position, after the limiting piece 300 is separated from the protection piece 200, the protection piece 200 can freely slide on the mounting piece 100; this structure design makes the protection mechanism can flexibly switch the working state according to the actual needs, simple and convenient operation, convenient for users to easily move away the protection piece 200 when needing to use the surface to be protected 710, and quickly restore the protection mechanism to the protection position when needing to protect the surface to be protected 710.

[0053] Reference Figures 8 to 10 In an embodiment, one of the protection piece 200 and the mounting piece 100 is provided with a first sliding protrusion 220, and the other is provided with a first sliding groove 110, the first sliding groove 110 is arranged along a first direction, and the protection piece 200 slides on the mounting piece 100 by sliding in the first sliding groove 110 along the first direction through the first sliding protrusion 220; one of the limiting piece 300 and the mounting piece 100 is provided with a second sliding protrusion 320, and the other is provided with a second sliding groove 120, the second sliding groove 120 is arranged along a second direction, the second direction is arranged intersecting the first direction, and the limiting piece 300 slides on the mounting piece 100 by sliding in the second sliding groove 120 along the second direction through the second sliding protrusion 320.

[0055] The first direction and the second direction intersect, so that the protector 200 and the limiting piece 300 can slide in independent directions; the protector 200 slides along the first direction, and the limiting piece 300 slides along the second direction, so that the positions of the two can be accurately adjusted by respectively controlling their sliding in the respective sliding grooves; when it is needed to block the sliding of the protector 200, the limiting piece 300 can be slid along the second direction to a position in contact with the protector 200, so as to realize the blocking function; and when it is needed to allow the protector 200 to slide, the limiting piece 300 is slid away along the second direction, so that it is separated from the protector 200.

[0056] Meanwhile, the first sliding convex part 220 and the first sliding groove 110 used in cooperation provide accurate guidance for the sliding of the protector 200, so that the protector 200 can accurately reach a predetermined position along the first direction; the second sliding convex part 320 and the second sliding groove 120 used in cooperation provide accurate guidance for the sliding of the limiting piece 300, so that the limiting piece 300 can accurately reach a predetermined position along the second direction; the above structure design improves the accuracy and stability of the operation of the protection mechanism.

[0057] Referring to Figures 8 to 10 In an embodiment, the first sliding convex part 220 is arranged on the protector 200, and the first sliding groove 110 is arranged on the mounting piece 100; the second sliding convex part 320 is arranged on the limiting piece 300, and the second sliding groove 120 is arranged on the mounting piece 100.

[0058] In the embodiment, the first sliding convex part 220 is fixedly arranged on the protector 200, and the second sliding convex part 320 is fixedly arranged on the limiting piece 300. It can be understood that the first sliding convex part 220 and the second sliding convex part 320 can also be arranged on the mounting piece 100, the first sliding groove 110 is arranged on the protector 200, and the second sliding groove 120 is arranged on the mounting piece 100.

[0059] The first sliding convex part 220 is arranged on the protector 200, and compared with arranging the first sliding groove 110 on the protector 200, the overall structure of the protector 200 can be more complete and stronger. Meanwhile, the second sliding convex part 320 is arranged on the limiting piece 300, and compared with arranging the second sliding groove 120 on the limiting piece 300, the overall structure of the limiting piece 300 can also be more complete and stronger. In addition, arranging the first sliding groove 110 and the second sliding groove 120 on the mounting piece 100 also facilitates manufacturing and processing, and helps to reduce the manufacturing difficulty.

[0060] Referring to Figures 1 to 10In an embodiment, the to-be-protected piece 700 further has a reference surface 730, which is located between the to-be-protected surface 710 and the back surface 720; when the protection mechanism is in the protection position, the surface of the protection piece 200 on the side of the reference surface 730 away from the to-be-protected surface 710 is the protection surface 230, the surface of the limiting piece 300 on the side of the reference surface 730 away from the to-be-protected surface 710 is the limiting surface 330, and the limiting surface 330 is located on the side of the protection surface 230 away from the reference surface 730.

[0061] In the embodiment, the reference surface 730 is a side surface of the to-be-protected piece 700. In the process of switching the protection mechanism from the protection position to the avoidance position, the limiting piece 300 is first pushed to move in the second direction by applying a pushing force to the limiting piece 300, and after the limiting piece 300 is separated from the protection piece 200, the protection piece 200 is pushed to move in the first direction by applying a pushing force to the protection surface 230. The limiting surface 330 is located on the side of the protection surface 230 away from the reference surface 730, which helps the operator to first push the limiting surface 330 of the limiting piece 300 and then push the protection surface 230 of the protection piece 200, so that the limiting surface 330 and the protection surface 230 have a clear positional relationship and sequence, which helps to clarify the operation sequence, reduces the operation difficulty, is not prone to errors, and improves the convenience and efficiency of operation.

[0062] Referring to Figures 1 to 10 In an embodiment, one of the limiting piece 300 and the mounting piece 100 provided with the first sliding groove 110 is provided with a third sliding groove 130, the third sliding groove 130 is provided in the first direction and communicates with the second sliding groove 120, the to-be-protected surface 710, the back surface 720, the second sliding groove 120, and the third sliding groove 130 are sequentially arranged, and the limiting piece 300 slides on the mounting piece 100 in the first direction in the third sliding groove 130 through the second sliding protrusion 320; in the process of switching the protection mechanism from the protection position to the avoidance position, the limiting piece 300 first slides on the mounting piece 100 in the second direction and then slides on the mounting piece 100 in the first direction; after the limiting piece 300 slides on the mounting piece 100 in the first direction, the protection piece 200 can slide on the mounting piece 100 in the first direction.

[0063] In the embodiment, the third sliding groove 130 is arranged on the mounting piece 100, the third sliding groove 130 is arranged on the side of the second sliding groove 120 away from the back surface 720, and the second sliding protrusion 320 penetrates into the third sliding groove 130 for sliding in the first direction in the third sliding groove 130.

[0064] The limiting piece 300 first slides along the second direction and separates from the protection piece 200 first, and then slides along the first direction, in the process, the movement of the limiting piece 300 can accurately control the movement timing and path of the protection piece 200; only when the limiting piece 300 slides along the first direction, the protection piece 200 can slide along the first direction, which can ensure that the protection piece 200 moves at the right time and under the right conditions, and improves the accuracy and controllability of the entire protection mechanism.

[0065] In addition, the limiting piece 300 and the protection piece 200 slide along the first direction on the mounting piece 100, which not only makes the limiting piece 300 and the protection piece 200 keep the same slope movement, but also makes the stress direction of the limiting piece 300 and the protection piece 200 consistent; the above structure design can make the stress of the limiting piece 300 and the protection piece 200 more uniform, which not only helps to ensure the stability and accuracy of the movement of the limiting piece 300 and the protection piece 200; at the same time, it also makes the pressure and friction force of each part of the limiting piece 300 and the protection piece 200 more balanced during the movement process, optimizes the mechanical properties, and prolongs the service life of the limiting piece 300 and the protection piece 200.

[0066] Reference Figures 1 to 10 In an embodiment, the protection piece 200 has two adjacent and perpendicular reference surfaces 730, the number of protection pieces 200 is two, the two protection pieces 200 are connected to each other and perpendicular to each other, and are respectively arranged one-to-one with the two reference surfaces 730; the number of limiting pieces 300 is also two, the two limiting pieces 300 are connected to each other and are respectively arranged one-to-one with the two protection pieces 200.

[0067] In the embodiment, the two protection pieces 200 are one-piece, and the two limiting pieces 300 are one-piece; the first sliding groove 110, the second sliding groove 120 and the third sliding groove 130 are through grooves, the first sliding convex part 220 is fixedly installed on the two protection pieces 200, and the second sliding convex part 320 is fixedly installed on the two limiting pieces 300.

[0068] The two protection pieces 200 can effectively protect the protection piece 700 from two different directions, effectively covering the key parts of the protection piece 700; compared with a single protection piece 200, the two protection pieces 200 provide more comprehensive protection, reducing the risk of damage to the protection piece 700 from different angles of collision, friction and the like.

[0069] Meanwhile, the two limiting members 300 are correspondingly arranged with the two protection members 200, which can limit the protection members 200 in two directions; when the protection mechanism is in the protection position, the limiting members 300 can prevent the protection members 200 from moving in two perpendicular directions, further enhancing the fixing effect of the protection members 200, preventing displacement due to external force, and ensuring stable protection for the to-be-protected member 700.

[0070] In addition, the two protection members 200 are connected with each other and perpendicular to each other, and the two limiting members 300 are also connected with each other, so that the protection mechanism is formed as a more integral structure; such a structure design not only can reduce the gap and looseness between parts, make the entire protection mechanism more compact, and occupy less space; at the same time, it is also helpful to improve the overall strength and rigidity of the entire protection mechanism.

[0071] In addition, in order to strengthen the smoothness of the protection member 200 and the limiting member 300 sliding on the mounting member 100, the number of the first sliding convex parts 220 is two, the two first sliding convex parts 220 are arranged in the direction from the to-be-protected surface 710 to the back surface 720, the number of the first sliding grooves 110 is two, and the two first sliding convex parts 220 are correspondingly arranged with the two first sliding grooves 110. The number of the second sliding convex parts 320 is two, the two second sliding convex parts 320 are arranged in the direction from the to-be-protected surface 710 to the back surface 720, the number of the second sliding grooves 120 and the third sliding grooves 130 is two, and the two second sliding convex parts 320 are correspondingly arranged with the two second sliding grooves 120 and the two third sliding grooves 130.

[0072] Referring to Figure 9 and Figure 11 In an embodiment, a rolling member 400 is arranged between the limiting member 300 and the mounting member 100, and the limiting member 300 and the mounting member 100 are used to roll with the rolling member 400.

[0073] In the embodiment, the rolling member 400 can be a roller, a ball, a roller, a needle, a ball bearing or a roller bearing. The rolling member 400 is in contact with the surface of the limiting member 300 close to the mounting member 100, and in contact with the surface of the mounting member 100 close to the limiting member 300.

[0074] By setting the rolling member 400, the frictional resistance between the limiting member 300 and the mounting member 100 can be greatly reduced, the limiting member 300 moves more smoothly on the mounting member 100, effectively reduces the external force required to push the limiting member 300, and makes the operation of adjusting the position of the protection mechanism more convenient. At the same time, due to the reduction of friction, the wear between the limiting member 300, the mounting member 100 and the rolling member 400 is also significantly reduced, which helps to prolong the service life of the limiting member 300, the mounting member 100 and the rolling member 400. In addition, the noise generated by rolling friction is lower than that by sliding friction, and this structural design helps to reduce the noise generated when the protection mechanism moves.

[0075] With reference to Figure 9 And Figure 11 In an embodiment, the limiting member 300 is provided with a limiting area 340 near the surface of the mounting member 100; the rolling member 400 is a plurality of rolling balls.

[0076] In this embodiment, the surface of the limiting member 300 near the mounting member 100 is concave in the direction away from the mounting member 100 to form a limiting area 340; the adjacent two rolling balls contact each other.

[0077] The plurality of rolling members 400 roll in the limiting area 340, which can more evenly distribute the pressure between the limiting member 300 and the mounting member 100 than a single rolling member 400, effectively reducing the contact area and further reducing the friction, making the sliding of the limiting member 300 more smooth. At the same time, the plurality of rolling members 400 jointly bear the force between the limiting member 300 and the mounting member 100, which can withstand greater load, helping to improve the carrying capacity and stability of the protection mechanism. In addition, the plurality of rolling members 400 roll in the limiting area 340, which can better adapt to the movement of the limiting member 300 in different directions, improving the movement accuracy and reliability of the protection mechanism.

[0078] With reference to Figure 9 And Figure 11 In an embodiment, the limiting member 300 protrudes two limiting screws 350 near the surface of the mounting member 100, the two limiting screws 350 are spaced apart, and the plurality of rolling balls are arranged between the two limiting screws 350. The area between the two limiting screws 350 is the limiting area 340.

[0079] In the embodiment, the limiting member 300 is provided with a mounting hole away from the surface of the mounting member 100, the mounting hole penetrates the surface of the limiting member 300 close to the mounting member 100, and the hole wall of the mounting hole is provided with internal threads threadedly matched with the external threads of the limiting screw 350; the two limiting screws 350 are arranged in the direction from the surface to be protected 710 to the back surface 720. It can be understood that the limiting area 340 can also be a limiting groove provided on the surface of the limiting member 300 close to the mounting member 100, and the limiting groove has two groove walls oppositely arranged in the direction from the surface to be protected 710 to the back surface 720 to prevent the rolling member 400 from escaping from the limiting groove.

[0080] The limiting screw 350 is arranged to not only clearly define the movement range of the rolling member 400, but also accurately limit the rolling member 400 in the area between the two limiting screws 350, thereby ensuring the relative movement accuracy between the limiting member 300 and the mounting member 100. Meanwhile, the limiting screw 350 is also convenient to install on the limiting member 300 to form the limiting area 340, and convenient to adjust and replace the rolling member 400 during installation and maintenance; specifically, if the rolling member 400 needs to be checked or replaced, the limiting screw 350 is only needed to be removed from the limiting member 300 to take out the rolling member 400 from the limiting area 340, and after the checking or replacement operation is completed, the limiting screw 350 is installed back to the original position.

[0081] Referring to Figure 9 and Figure 10 In an embodiment, the protection mechanism further comprises a first reset member 500, which is arranged between the protection member 200 and the mounting member 100, and is used to push the protection member 200 in the protection mechanism to switch from the avoidance position to the protection position.

[0083] The arranged first reset member 500 can automatically push the protection member 200 back to the protection position after the protection mechanism switches from the protection position to the avoidance position, which not only can continuously provide protection for the surface to be protected 710 of the protected member 700, but also does not need manual intervention, thereby simplifying the reset process.

[0084] Referring to Figure 9 and Figure 10 In an embodiment, the protection mechanism further comprises a second reset member 600, which is arranged between the limiting member 300 and the mounting member 100, and is used to push the limiting member 300 in the protection mechanism to switch from the avoidance position to the protection position.

[0085] In the embodiment, the second reset member 600 can be an elastic rubber rod, a gas spring, a tension spring or a compression spring, the first end of the second reset member 600 is in contact with the limiting member 300, and the second end of the second reset member 600 is in contact with the mounting member 100.

[0086] The second reset member 600 provided can automatically push the limiting member 300 back to the protection position after the protection structure is switched from the protection position to the avoidance position, so that the entire protection mechanism is automatically switched from the avoidance position to the protection position. The first reset member 500 and the second reset member 600 used in cooperation can not only realize cooperative resetting, but also optimize the stress condition of the protection mechanism during the resetting process; in addition, the protection mechanism can be more quickly and accurately pushed back to the protection position, at which time the protection member 200 cannot move on the mounting member 100 under the limiting action of the limiting member 300, thereby providing more effective protection for the protection surface 710 of the to-be-protected member 700.

[0087] Referring to Figure 9 and Figure 10 In an embodiment, the first reset member 500 is a compression spring, the protection member 200 is provided with a first limiting column 240, the mounting member 100 is provided with a second limiting column 140, the first reset member 500 is sleeved on the first limiting column 240 and the second limiting column 140.

[0089] The first reset member 500 is a compression spring, so that the protection member 200 can be smoothly switched from the protection position to the avoidance position under the action of a smaller pushing force; at the same time, the compression spring also has good elastic resetting ability, buffering and damping ability and can provide relatively uniform and stable elastic force, which is beneficial to the accurate return of the protection member 200 to the preset protection position, thereby improving the resetting accuracy and reliability of the protection mechanism. The first limiting column 240 and the second limiting column 140 provided provide an accurate installation position and guide for the first reset member 500, and ensure that the first reset member 500 does not deviate or shake during the working process.

[0090] Referring to Figures 1 to 13 and Figures 1 to 13In an embodiment, the second reset member 600 is a compression spring, the limiting member 300 is provided with a third limiting column 360, and the mounting member 100 is provided with a fourth limiting column 150. The second reset member 600 is sleeved on the third limiting column 360 and the fourth limiting column 150.

[0091] In the embodiment, the third limiting column 360 is fixedly installed on the surface of the limiting member 300 close to the mounting member 100, the length direction of the third limiting column 360 is parallel to the first direction, and part of the structure of the second reset member 600 is sleeved on the third limiting column 360.

[0092] The second reset member 600 is a compression spring, so that the limiting member 300 can be smoothly switched from the protection position to the avoiding position under the action of a small pushing force. Meanwhile, the compression spring has good elastic reset ability, buffering and damping ability, and can provide relatively uniform and stable elastic force, which is beneficial to the accurate return of the limiting member 300 to the preset protection position, thereby improving the reset precision and reliability of the protection mechanism. The third limiting column 360 and the fourth limiting column 150 provide an accurate installation position and guide for the second reset member 600, and ensure that the second reset member 600 will not deviate or shake during work.

[0093] Reference Figures 1 to 13 According to another aspect of the present application, the embodiment of the present application further provides a display device, which comprises a display screen body and the above-mentioned protection mechanism. The protection mechanism is arranged on the display screen body. The display screen body has a display surface and a back surface 720 arranged oppositely. When the protection mechanism is in the protection position, at least part of the structure of the protection member 200 is located on the side of the display surface away from the back surface 720. The display screen body is formed as the to-be-protected member 700, and the display surface is formed as the to-be-protected surface 710 of the to-be-protected member 700.

[0094] In the embodiment of the present application, the mounting member 100 is fixedly installed on the back surface 720 or other surface of the display screen body by a connecting screw.

[0095] In the present application, when the protection mechanism is in the protection position, the limiting member 300 blocks the sliding of the protection member 200 on the mounting member 100 by contacting the protection member 200, so that the protection member 200 can stably stay on the side of the display surface away from the back surface 720. In this case, the protection member 200 will not slide due to a small external force, but can effectively block the damage caused by the collision, scratching and the like of the external environment to the display surface, thereby providing stable and reliable protection for the display surface and prolonging the service life of the display surface and the display screen body.

[0096] In addition, after the limiting piece 300 is separated from the protection piece 200 when the protection mechanism is switched from the protection position to the avoiding position, the protection piece 200 can freely slide on the mounting piece 100. This structure design enables the protection mechanism to flexibly switch the working state according to the actual needs, and the operation is simple and convenient, which facilitates the user to easily move the protection piece 200 away when the display surface is needed to be used, and quickly restores the protection mechanism to the protection position when the display surface is needed to be protected.

[0097] Referring to ​ In an embodiment, the display screen body further has a docking face, the docking face is located between the display surface and the back face 720, and part of the structure of the protection piece 200 is located on the side of the docking face away from the display surface when the protection mechanism is in the protection position. The number of the display screen bodies is multiple. In the process of assembling the two adjacent display screen bodies, the protection pieces 200 of the two protection mechanisms contact and then slide on the corresponding mounting pieces 100. When the protection pieces 200 of the two protection mechanisms are both slid to the avoiding position, the docking faces of the two display screen bodies contact.

[0098] In the embodiment, the docking face is the side face of the display screen body and is the reference face 730 in the protection piece 700. In the process of assembling the two display screen bodies, the two protection mechanisms are first brought close to each other. In this process, the limiting piece 300 in one protection mechanism first contacts the limiting piece 300 in the other protection mechanism, and the two limiting pieces 300 move in the second direction under the action of the mutual pushing force. After the limiting piece 300 is separated from the protection piece 200, the protection piece 200 in one protection mechanism contacts the protection piece 200 in the other protection mechanism, and the two protection pieces 200 move in the first direction under the action of the mutual pushing force. After the two protection mechanisms are both moved to the avoiding position, the two docking faces of the two display screen bodies contact. The above structure design can accurately splice the multiple display screen bodies together, which helps to improve the assembly efficiency and reduce the assembly difficulty.

[0099] Meanwhile, in the non-assembly state, i.e., when the protection mechanism is in the protection position, part of the structure of the protection piece 200 is located on the side of the docking face away from the display surface, which can protect the docking face of the display screen body, prevent the docking face from being damaged by collision, scratching, etc. during transportation, storage or use, ensure the flatness and integrity of the docking face, and be conducive to ensuring the overall effect and performance of the spliced multiple display screen bodies.

[0100] Referring to ​In an embodiment, the display screen body has four corners, and a protection mechanism is arranged at each of the four corners. The corners of the display screen body are the most vulnerable parts to collision and damage. Arranging a protection mechanism at each of the four corners can comprehensively protect the display screen body, effectively reduce the risk of damage such as breakage or corner loss due to accidental impact or falling, and help prolong the service life of the display screen body.

[0101] In summary, the protection mechanism and the display device provided by the embodiment have at least the following beneficial technical effects: in the present application, when the protection mechanism is in the protection position, the limiting piece 300 blocks the sliding of the protection piece 200 on the mounting piece 100 by contacting the protection piece 200, so that the protection piece 200 can stably stay on the side away from the back surface 720 of the display surface; in this case, the protection piece 200 will not slide due to small external force, but can effectively block the damage to the display surface caused by external collision, scratching, etc., provide stable and reliable protection for the display surface, and prolong the service life of the display surface and the display screen body.

[0102] In addition, when the protection mechanism is switched from the protection position to the avoidance position, after the limiting piece 300 is separated from the protection piece 200, the protection piece 200 can freely slide on the mounting piece 100; this structure design makes the protection mechanism can flexibly switch the working state according to the actual needs, the operation is simple and convenient, and the user can easily move the protection piece 200 when using the display surface, and quickly restore the protection mechanism to the protection position when protecting the display surface.

[0103] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
