[0062] This application provides a display screen splicing device and a spliced ​​display device. To make the purpose, technical solution, and effects of this application more clear and explicit, the application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0063] Currently, in a spliced ​​display device, there are technical problems in that the display screen to be disassembled is easily damaged during the disassembly process and the disassembly is difficult.

[0064] 1a to 1b and 2a to 2b , an embodiment of the present invention provides a display screen splicing device 100, comprising:

[0065] base 110;

[0066] The support assembly 120 is fixedly connected to one side of the base 110 .

[0067] The distance adjustment assembly 130 is disposed on the same side of the base 110 as the support assembly 120;

[0068] A bearing assembly 140 connected to the support assembly 120 and the distance adjustment assembly 130 , wherein the bearing assembly 140 includes at least two groups of bearing members 141 arranged along a first direction Y, wherein the first direction Y is parallel to the extension direction of the support assembly 120 ;

[0069] The distance adjustment assembly 130 moves along the first direction Y, driving at least one group of the bearing members 141 to move in the same direction as the distance adjustment assembly 130 .

[0070] In the embodiment of the present invention, the distance adjustment component 130 is set. When the distance adjustment component 130 moves relative to at least one group of supporting members 141 along the first direction Y, it drives at least one group of supporting members 141 to move in the same direction as the distance adjustment component 130, so that the at least one group of supporting members 141 driven by the distance adjustment component 130 is spaced apart from the supporting component 140 adjacent to it in the first direction Y, thereby facilitating the disassembly of the display screen on the supporting component 140 and reducing damage to the display screen caused by disassembly.

[0071] The technical solution of the present invention will now be described in conjunction with specific embodiments.

[0072] Referring to Figures 1a-1b and 2a-2b, in this embodiment, the distance adjustment assembly 130 includes a plurality of first through holes 131 arranged along the first direction Y, and a group of supporting members 141 extends within a first through hole 131. Each group of supporting members 141 extends within a corresponding first through hole 131, thereby enabling connection between each group of supporting members 141 and the distance adjustment assembly 130. This facilitates the distance adjustment assembly 130 controlling the movement distance of the corresponding supporting member 141 in the first direction Y by using the length of each first through hole 131. The supporting member 141 is used to support a display screen. Therefore, the distance adjustment assembly 130 controls the movement distance of the display screen connected to the corresponding supporting member 141 in the first direction Y by using the length of each first through hole 131.

[0073] Please refer to Figures 1a to 1b, and Figures 2a to 2b. In some embodiments, the lengths of the plurality of first through holes 131 in the first direction Y decrease successively along the direction away from the base 110; the length of the first through hole 131 in the first direction Y, that is, the distance along the first direction Y between one end of each first through hole 131 close to the base 110 and the other end of the first through hole 131 away from the base 110. The lengths of the multiple first through holes 131 decrease in the direction away from the base 110. When the distance adjustment component 130 moves in the direction away from the base 110, it first drives a group of the supporting members 141 farthest from the base 110 to move relative to the other supporting members 141; then, in the direction close to the base 110, multiple groups of the supporting members 141 move relative to the base 110 in turn and the moving distance decreases in turn until the supporting member 141 where the display screen to be disassembled is located moves relative to the base 110 and increases the distance between it and the adjacent display screen in the first direction Y, so as to facilitate the disassembly of the detachable display screen and reduce damage to the display screen caused by the disassembly process.

[0074] 1a-1b and 2a-2b , in some embodiments, the distance adjustment assembly 130 includes a first distance adjustment member 132 and a second distance adjustment member 133 located at opposite ends of the base 110 along a second direction X, where the second direction X intersects the first direction Y. The supporting member 141 extends along the second direction X and is connected to the first distance adjustment member 132 and the second distance adjustment member 133 , respectively.

[0075] Please refer to Figures 1a to 1b, and Figures 2a to 2b. In some embodiments, each of the first through holes 131 includes a first sub-through hole located in the first distance adjusting member 132 and a second sub-through hole located in the second distance adjusting member 133, and each group of the supporting members 141 extends along the second direction X into one of the first sub-through holes and one of the second sub-through holes, respectively.

[0076] In some embodiments, along the extension direction of the supporting member 141, the orthographic projection of the second sub-through hole on the first distance adjustment member 132 coincides with the first sub-through hole. This allows the distance adjustment assembly 130 to control the movement of the supporting member 141 along the first direction Y. Each first sub-through hole and the corresponding second sub-through hole have the same control effect on the movement of the supporting member 141, preventing the supporting member 141 from tilting toward the first distance adjustment member 132 or the second distance adjustment member 133 during movement, thereby preventing damage to the display screen.

[0077] Please refer to Figures 1a to 1b and Figures 2a to 2b. In this embodiment, the support assembly 120 includes a plurality of second through holes 121 arranged along the first direction Y, the first through holes 131 and the second through holes 121 are arranged in a one-to-one correspondence, and a group of the supporting members 141 extends into one of the second through holes 121.

[0078] The support assembly 120 is fixed to the base 110, and each set of the supporting members 141 extends into a corresponding one of the second through holes 121 to obtain supporting force, thereby arranging the multiple sets of the supporting members 141 along the first direction Y. When the spliced ​​display device is in normal operation, that is, when the distance adjustment assembly 130 is not moving relative to at least one set of the supporting members 141, the portion of each supporting member 141 extending into the second through hole 121 is in direct contact with the end of the second through hole 121 that is closest to the base 110 in the first direction Y.

[0079] Referring to Figures 1a-1b and 2a-2b, in some embodiments, the support assembly 120 is located between the first distance adjustment member 132 and the second distance adjustment member 133 along the second direction X. By disposing the support assembly 120 between the first distance adjustment member 132 and the second distance adjustment member 133, when the spliced ​​display device is in the display screen replacement state (as shown in Figures 2a, 2b, 4a, or 4b), that is, when the distance adjustment assembly 130 drives at least one group of the supporting members 141 to move relative to at least one group of the supporting members 141 along the first direction Y, the distance adjustment assembly 130 can be manually or electrically controlled.

[0080] In some embodiments, the support assembly 120 includes a first support member 122 and a second support member 123, respectively fixed at both ends of the base 110 along the second direction X. The first support member 122 is located on a side of the second support member 123 close to the first distance adjustment member 132. Each of the second through holes 121 includes a third sub-through hole located in the first support member 122 and a fourth sub-through hole located in the second support member 123. Each set of the supporting members 141 extends along the second direction X into one of the third sub-through holes and one of the fourth sub-through holes, respectively, so that each set of the supporting members obtains sufficient supporting force at both ends in the second direction X when in operation.

[0081] In some embodiments, along the extension direction of the supporting member 141, the orthographic projection of the fourth sub-through hole on the first supporting member 122 coincides with the third sub-through hole, so that the supporting forces obtained by both ends of each group of the supporting members 141 in the second direction X when in working state are equal, thereby avoiding damage to the display screen due to uneven force at both ends of the supporting member 141 in the second direction X.

[0082] 1a-1b and 2a-2b , in some embodiments, the lengths of the plurality of second through holes 121 in the first direction Y increase in sequence as they move away from the base 110. The length of each second through hole 121 in the first direction Y is, that is, the distance along the first direction Y between an end of each second through hole 121 closer to the base 110 and an end of the second through hole 121 farther from the base 110. Due to the action of the distance adjustment component 130, the group of bearing members 141 farthest from the base 110 among the multiple groups of bearing members 141 moves first, and moves the largest distance in the first direction Y, and the moving distances of the multiple groups of bearing members 141 decrease along the direction approaching the base 110. Therefore, accordingly, the lengths of the multiple second through holes 121 in the first direction Y increase successively along the direction away from the base 110, so as to avoid the length of the second through holes 121 limiting the moving distance of the bearing member 141, resulting in the display screen to be disassembled not being spaced apart from the adjacent display screen in the first direction Y.

[0083] In some embodiments, the length of any first through hole 131 in the first direction Y is greater than or equal to the length of the largest length among the plurality of second through holes 121 in the first direction Y. When the spliced ​​display device is in the display screen replacement state (as shown in FIG. 2a , FIG. 2b , FIG. 4a , or FIG. 4b ), since the actual movement distance of each group of the supporting members 141 needs to be controlled by the distance adjustment assembly 130 , that is, it needs to be controlled by the length of the corresponding first through hole 131 to which each group of the supporting members 141 extends in the first direction Y, the length of any first through hole 131 in the first direction Y is greater than or equal to the length of the largest length among the plurality of second through holes 121 in the first direction Y. This helps to prevent the length of the second through holes 121 in the first direction Y from limiting the actual movement distance of the supporting members 141.

[0084] In some embodiments, the distance adjustment component 130 is separately arranged from the base 110. When the spliced ​​display device operates normally (as shown in Figure 1a, Figure 1b, Figure 3a or Figure 3b), the distance adjustment component 130 provides supporting force through the supporting member 141. Therefore, the portion of each supporting member 141 extending into the first through hole 131 is in direct contact with the end of the first through hole 131 away from the base 110 in the first direction Y.

[0085] In some embodiments, the supporting assembly 140 includes N groups of supporting members 141 arranged along the first direction Y. Along the direction Y away from the first direction Y, the group of supporting members 141 closest to the base 110 is the first group of supporting members 141, and the group of supporting members 141 farthest from the base 110 is the Nth group of supporting members 141, where N is an integer greater than or equal to 2.

[0086] Along the direction away from the base 110, the length in the first direction Y of the first through holes 131 connected to the mth group of bearing members 141 is equal to the length in the first direction Y of the second through holes 121 connected to the (N-m+1)th group of bearing members 141. m is an integer greater than or equal to 1 and less than or equal to N. Along the direction away from the base 110, the lengths of the first through holes 131 in the first direction Y decrease, while the lengths of the second through holes 121 in the first direction Y increase. When the lengths of the first through holes 131 and the second through holes 121 in the first direction Y satisfy the aforementioned relationship, the distance adjustment assembly 130 controls the movement of the bearing members 141 in the first direction Y without being restricted by the lengths of the second through holes 121 in the first direction Y. The lengths of the second through holes 121 in the first direction Y can be set based on the lengths of the first through holes 131 in the first direction Y, simplifying the design.

[0087] In some embodiments, along the first direction Y, the difference in lengths of the first through holes 131 connected to any two adjacent groups of the bearing members 141 in the first direction Y is the same, which facilitates that the distances separating the two adjacent groups of the bearing members 141 in the first direction Y, among the multiple groups of the bearing members 141 that are moved under the control of the distance adjustment assembly 130, are the same. For example, the difference in lengths of the first through holes 131 connected to the kth group of the bearing members 141 in the first direction Y and the lengths of the first through holes 131 connected to the (k-1)th group of the bearing members 141 in the first direction Y is the (k-1)th difference, where k is an integer greater than 3 and less than or equal to N; the difference in lengths of the first through holes 131 connected to the second group of the bearing members 141 in the first direction Y and the lengths of the first through holes 131 connected to the first group of the bearing members 141 in the first direction Y is the first difference; and the first difference is the same as the (k-1)th difference.

[0088] Referring to FIG. 1 a to FIG. 1 b and FIG. 2 a to FIG. 2 b , in some embodiments, the supporting member 141 includes a rotating shaft 141 a , and the rotating shaft 141 a extends into the first through hole 131 and the second through hole 121 .

[0089] In some embodiments, the rotating shaft member 141a can be cylindrical or elliptical. When the rotating shaft member 141a is elliptical, the diameter of the rotating shaft member 141a in the first direction Y is the maximum distance between one end of the rotating shaft member 141a close to the base 110 in the first direction Y and the other end of the rotating shaft member 141a away from the base 110 in the first direction Y.

[0090] In some embodiments, each of the rotating shaft members 141a includes a first rotating shaft portion located within the first through hole 131, a second rotating shaft portion located within the second through hole 121, and a third rotating shaft portion excluding the first rotating shaft portion and the second rotating shaft portion. The diameter of the first rotating shaft portion of at least one rotating shaft member 141a in the first direction Y is less than or equal to the diameter of the third rotating shaft portion in the first direction Y, and / or the diameter of the second rotating shaft portion of at least one rotating shaft member 141a in the first direction Y is less than or equal to the diameter of the third rotating shaft portion in the first direction Y. When the diameter of the first rotating shaft portion or the second rotating shaft portion of a rotating shaft member 141a in the first direction Y is less than the diameter of the third rotating shaft portion in the first direction Y, it is beneficial to prevent the rotating shaft member 141a from moving in the second direction X, thereby preventing the rotating shaft member 141a from falling out of the first through hole 131 or the second through hole 121 and damaging components such as the display screen. Preferably, the diameter of the third rotating shaft portion of the rotating shaft member 141a in the first direction Y is greater than the length of the first through hole 131 connected to the rotating shaft member 141a in the first direction Y; and / or, the diameter of the third rotating shaft portion of the rotating shaft member 141a in the first direction Y is greater than the length of the second through hole 121 connected to the rotating shaft member 141a in the first direction Y.

[0091] Referring to Figures 1a-1b and 2a-2b, in some embodiments, along a direction away from the base 110, the length of the first through holes 131 connected to the Nth group of bearing members 141 in the first direction Y is greater than or equal to the diameter of the rotating shaft 141a of the Nth group of bearing members 141 in the first direction Y. Specifically, the length of the first through holes 131 connected to the Nth group of bearing members 141 in the first direction Y is greater than or equal to the diameter of the first rotating shaft portion of the rotating shaft 141a of the Nth group of bearing members 141 in the first direction Y.

[0092] The length of the second through hole 121 connected to the Nth group of bearing members 141 in the first direction Y is greater than the length of the first through hole 131 connected to the (N-1)th group of bearing members 141, so that when the Nth group of bearing members 141 and the (N-1)th group of bearing members 141 move in the first direction Y, a distance between the two can be increased.

[0093] Referring to Figures 1a-1b and 2a-2b, in some embodiments, along a direction away from the base 110, the length of the second through holes 121 connected to the first group of bearing members 141 in the first direction Y is greater than or equal to the diameter of the rotating shaft 141a of the first group of bearing members 141 in the first direction Y. Specifically, the length of the second through holes 121 connected to the first group of bearing members 141 in the first direction Y is greater than or equal to the diameter of the second rotating shaft portion of the rotating shaft 141a of the first group of bearing members 141 in the first direction Y.

[0094] The length of the first through hole 131 connected to the first group of bearing members 141 is greater than the length of the second through hole 121 connected to the second group of bearing members 141, so that when the first group of bearing members 141 and the second group of bearing members 141 move in the first direction Y, a distance between them can be increased.

[0095] In some embodiments, along a direction away from the base 110 , a length D1 of the first through hole 131 in the first direction Y may be calculated as follows: D1=L+(Nm)×∆.

[0096] Along the direction away from the base 110 , the length D2 of the second through hole 121 in the first direction Y may be calculated as: D2=L+(m−1)×∆.

[0097] Wherein, m represents the mth first through hole 131 corresponding to the mth group of the bearing members 141 in the direction away from the base 110; L represents the diameter of the rotating shaft 141a; N represents the total number of the first through holes 131; ∆ represents the distance that each group of the bearing members 141 needs to be stretched in the first direction Y.

[0098] In some embodiments, N is an integer greater than or equal to 2, preferably, N is greater than or equal to 3, for example, it can be 5, 10, 50...100, etc.; m is a positive integer less than or equal to N; L can be less than or equal to 1 cm, for example, it can be 0.3 mm, 0.4 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.8 mm, 0.9 mm, etc.; ∆ is greater than or equal to 0.5 cm and less than or equal to 3 cm, for example, it can be 0.8 cm, 0.9 cm, 1 cm, 1.2 cm, 1.4 cm, 1.5 cm, 1.8 cm, 2 cm, 2.5 cm, 2.8 cm, etc.
