The splicing assembly 2 comprises a first splicing member 21 and a second splicing member 22 which are respectively installed on two adjacent splicing units, the first splicing member 21 comprises a body part 211 and a first boss 212 which is arranged on one side of the body part 211 in a protruding mode, a second protrusion 213 is arranged on one side, away from the body part 211, of the first boss 212 in a protruding mode, namely the first boss 212 is provided with the second boss 213 in a protruding mode along the protruding direction of the first boss; the second splicing element 22 is provided with a butt groove 221. The splicing assembly 2 further comprises a locking mechanism 23, in the splicing state, the second boss 213 is matched with the butt-joint groove 221, for example, the second boss 213 is inserted into the butt-joint groove 221, the first boss 212 is located between the body portion 211 and the second splicing member 22, that is, the first boss 212 is located outside the body portion 211 and the second splicing member 22, and the first splicing member 21 and the second splicing member 22 are spliced through the locking mechanism 23, that is, the two can be directly locked with each other or indirectly locked with each other.

As shown in fig. 1 to 4, when the splicing assembly 2 is applied to a spliced screen, the first splicing element 21 is installed on the first splicing unit 11, the second splicing element 22 is installed on the second splicing unit 12, and in a splicing state (i.e. the first splicing unit 11 and the second splicing unit 12 are in the splicing state), along a direction perpendicular to the main surface of the splicing unit, the projection of the first boss 212 is at least partially located between the first splicing unit 11 and the second splicing unit 12, that is, the first boss 212 may be completely located between the first splicing unit 11 and the second splicing unit 12, or may be only partially located between the first splicing unit 11 and the second splicing unit 12.

In the spliced state, the protruding direction preferably coincides with the arrangement direction of the first splicing unit 11 and the second splicing unit 12, and may be a horizontal direction. The main surface of the splicing unit refers to a writing surface or a display surface of the first splicing unit 11 or the second splicing unit 12, and when the writing surface or the display surface is a plane, the main surface refers to a direction perpendicular to the plane; when the two are curved surfaces, the direction perpendicular to the plane is the direction when the two are unfolded into the plane.

In the above embodiment, the first splicing member 21 is provided with the first boss 212 and the second boss 213, the second splicing member 22 is provided with the butt-joint groove 221, when two adjacent splicing units are spliced, the second boss 213 is inserted into the butt-joint groove 221, so that the splicing of the two splicing units is realized, and the first boss 212 is located between the body portion 211 and the second splicing member 22, so that in the projection in the direction perpendicular to the main surface of the splicing units, at least part of the first boss 212 is located between the two splicing units, that is, the first boss 212 can leave a gap between the two splicing units, so that the first boss 212 is constrained, two adjacent splicing units cannot be too close to and mutually extrude each other in the splicing process, the possibility of touching between the two splicing units is reduced, and the damage probability of the splicing units in the splicing process is reduced. After the first splicing member 21 and the second splicing member 22 are spliced through the second boss 213 and the butt joint groove 221, in order to prevent the first splicing unit 11 and the second splicing unit 12 from being separated due to loosening in the using process and influence the using effect, the invention is further provided with the locking mechanism 23, and the two splicing units are locked through the locking mechanism 23 after the second boss 213 and the butt joint groove 221 are inserted, so that the reliability of connection of the spliced screen is improved.

In order to further increase the splicing reliability of two adjacent splicing units, the first boss 212, the second boss 213 and the butt joint groove 221 extend along the direction perpendicular to the protruding direction, that is, the first boss 212, the second boss 213 and the butt joint groove 221 extend continuously, the first boss 212 and the second boss 213 are in a strip structure, the butt joint groove 221 is in a strip groove, and the extending directions of the first boss 212, the second boss 213 and the butt joint groove 221 are consistent. Accordingly, the first splicing member 21 and the second splicing member 22 are strip-shaped structures, and the extending direction of the first splicing member and the extending direction of the second splicing member are consistent with the extending direction of the first boss 212, and in the splicing state, the extending direction can be a vertical direction, so that the gap between two adjacent splicing units can be limited in a larger range. Further, the first and

second bosses

212, 213 extend in the entire extending direction of the first splicing member 21, and the butt groove 221 penetrates the entire second splicing member 22 in the extending direction. Of course, a plurality of the first bosses 212 and the second bosses 213 may be provided at intervals along the extending direction, or only one of them may be provided at intervals along the extending direction.

In the process of splicing two adjacent splicing units, the volume of the splicing units is large, and particularly when the second bosses 213 extend along the extending direction, the second bosses 213 are difficult to align with the docking slots 221, which reduces the assembly efficiency. In order to solve this problem, in a preferred embodiment of the present invention, the area of the cross section of the second boss 213 (the cross section herein refers to the cross section perpendicular to the protruding direction) is gradually decreased along the protruding direction, for example, the second boss 213 is a wedge-shaped boss or a trapezoid-shaped boss, as shown in fig. 7; accordingly, the docking slot 221 includes at least a first variable section 2211 at the opening, the area of the cross section of the first variable section 2211 perpendicular to the opening direction is gradually increased along the opening direction of the docking slot 221 (in the spliced state, the opening direction of the docking slot 221 is opposite to the above-mentioned protruding direction), and the first variable section 2211 is adapted to the second boss 213, for example, the first variable section 2211 is a wedge-shaped groove or a trapezoid-shaped groove, as shown in fig. 6; in the splicing state, the second boss 213 is at least inserted into the first variable cross-section segment 2211, and the matching mode of the variable cross-section is adopted, so that the splicing of the two splicing units can be positioned, the alignment precision of the two splicing units is improved, and the installation is convenient.

More preferably, the cross section of the second boss 213 parallel to the protruding direction has a trapezoidal structure, that is, the second boss 213 is a trapezoidal boss; the cross section of the first variable cross-section 2211 parallel to the opening direction is a trapezoidal groove structure, that is, the first variable cross-section 2211 is a trapezoidal groove, as shown in fig. 4, the structure of the trapezoidal boss and the trapezoidal groove can further improve the alignment accuracy of two adjacent splicing units, and can improve the strength of the second boss 213, and is convenient to process.

With continued reference to fig. 6, the docking slot 221 may further include a first fixed section 2212, such as a rectangular groove, the first fixed section 2212 is connected to the small end of the first variable section 2211, and in the assembled state, a gap is left between the second boss 213 and the bottom of the first fixed section 2212, so as to facilitate the air in the docking slot 221 to be discharged when the second boss 213 is inserted into the docking slot 221, so that the insertion of the second boss 213 is smoother. It should be noted that, when the docking slot 221 only includes the first variable section 2211, a gap may be left between the second boss 213 and the bottom surface of the docking slot 221, that is, the protruding height of the second boss 213 is smaller than the depth of the docking slot 221.

Of course, the second protrusion 213 may be a rectangular protrusion, and the docking slot 221 may be a rectangular groove.

No matter how the second boss 213 and the abutting groove 221 are disposed, the first boss 212 and the second boss 213 can be integrally formed with the body 211, that is, the first splicing member 21 is formed by one-time processing, or integrally formed by injection molding, or can be separately processed and then mounted together. In a preferred embodiment, referring to fig. 4, 7-9, the first splicing element 21 further includes a matching portion 214 mounted on the body portion 211, in this embodiment, the first boss 212 and the second boss 213 are disposed on the matching portion 214, that is, the first boss 212, the second boss 213 and the body portion 211 are separate structures, and they are mounted together after being processed separately. Because two adjacent splicing units may need to be mutually detached and the first boss 212 is extruded for a long time, the first boss 212 and the second boss 213 are likely to be damaged, and therefore need to be maintained and replaced, only the first boss 212 and the second boss 213 can be replaced by adopting the split structure, so that the maintenance cost is saved; the split structure is convenient for processing each part; in addition, the split type can be adopted, the body portion 211, the first boss 212 and the second boss 213 can be made of different materials, and the materials of the first boss 212 and the second boss 213 can be more flexibly selected.

The main body 211 and the mating part 214 can be attached by means of adhesion, insertion, screw connection, etc. Preferably, the matching portion 214 includes a mounting structure 2141 connected to a side of the first boss 212 facing away from the second boss 213, i.e., the mounting structure 2141, the first boss 212 and the second boss 213 are connected in sequence. At this time, the body part 211 is provided with a mounting groove 2111 having an opening direction which is a protruding direction, and the mounting structure 2141 is mounted in the mounting groove 2111, that is, the first boss 212 and the second boss 213 are mounted to the body part 211 by the mounting structure 2141. During assembly, the entire mounting structure 2141 may be inserted directly from one end of the mounting slot 2111. By such a plug-in fitting manner, the reliability of the connection between the fitting portion 214 and the body portion 211 can be increased, and the reliability of the connection between the first splicing member 21 and the second splicing member 22 can be improved. The engaging portion 214 and the main body portion 211 are fitted to each other by insertion, but they may be connected by adhesion or screw connection at the same time.

In order to prevent the fitting portion 214 from being detached from the body portion 211, the mounting groove 2111 includes a second variable section 2111a and a second fixed section 2111b in the opening direction (where the opening direction coincides with the projection direction), a small end of the second variable section 2111a being connected to the second fixed section 2111b, and the opening area at the small end being smaller than that of the second fixed section 2111 b; the mounting structure 2141 is fittingly mounted to the second variable cross-section 2111a and the second constant cross-section 2111b, for example, the second variable cross-section 2111a is a trapezoidal groove or a wedge-shaped groove, and the second constant cross-section 2111b is a rectangular groove, and accordingly, the mounting structure 2141 also includes a variable cross-section sub-portion 2141a and a constant cross-section sub-portion 2141b connected to each other, the variable cross-section sub-portion 2141a is mounted to the second variable cross-section 2111a, and the constant cross-section sub-portion 2141b is mounted to the second constant cross-section 2111 b.

In the embodiment where the docking slot 221 includes the first variable section 2211 and the first fixed section 2212, it is preferable that the structure of the docking slot 221 is identical to that of the mounting slot 2111, so that the body 211 can be identical to that of the second splicing element 22, thereby facilitating the processing, and especially when both adopt sectional materials, the same mold can be used, thereby saving the cost.

In order to solve the above problem, in a preferred embodiment of the present invention, the first protrusion 212 protrudes from the periphery of the opening of the mounting groove 2111 and the docking groove 221, that is, in the protruding direction, the projection of the opening of the mounting groove 2111 and the projection of the opening of the docking groove 221 are both located in the outer edge of the projection of the first protrusion 212, which may be squeezed by the first splicing member 21 and the second splicing member 22, and the first protrusion 212 may be partially squeezed into the mounting groove 2111 or the docking groove 221, so that the gap between the two adjacent splicing units is reduced, and even touching occurs. Of course, the first boss 212 may extend only beyond the outer periphery of the mounting groove 2111 or the outer periphery of the docking groove 221.

Further, in order to better control the gap between two adjacent splicing units, both side surfaces of the first boss 212 in the protruding direction are planar, i.e. the first boss 212 is in surface contact with both the body portion 211 and the second splicing element 22, so as to better ensure the gap between two adjacent splicing units.

The protruding height of the first boss 212 is smaller than that of the second boss 213, so that the stability of the first boss 212 can be increased, the gap between the two splicing units can be ensured, and the alignment accuracy of the first splicing member 21 and the second splicing member 22 can be increased.

In a preferred embodiment, the first protrusion 212 is of a resilient structure, such as a plastic material, so that after two adjacent splicing units are spliced, the pressing force of the two splicing units can be buffered, and the two splicing units can be prevented from contacting and colliding better. Further, the entire fitting portion 214, and the first boss 212 and the second boss 213 provided thereon are made of the same material.

In the above embodiments, the locking mechanism 23 includes the first locking unit 231, the first locking unit 231 includes the hook 2311 and the clip 2312, and the hook 2311 and the clip 2312 can be detachably snap-fitted; one of the first splicing member 21 and the second splicing member 22 is connected with the hook 2311 (including direct connection and indirect connection), and the other is connected with the clamping member 2312 (including direct connection and indirect connection), for example, the connection is realized through two adjacent splicing units respectively, that is, the first splicing member 21 is connected with the hook 2311, and the second splicing member 22 is connected with the clamping member 2312; the second splicing piece 22 can be connected with a hook 2311, and the first splicing piece 21 is connected with a clamping piece 2312; or two adjacent splicing units are respectively connected with the hook 2311 and the clamping piece 2312, the first splicing piece 21 is installed on the first splicing unit 11, and the second splicing piece 22 is installed on the second splicing unit 12, so that the connection between the hook 2311 and the clamping piece 2312 and the first splicing piece 21 and the second splicing piece 22 is realized. It should be noted that the docking slot 221 and the hook 2311 may be connected to the same splicing unit or different splicing units. No matter which connection mode is adopted, when the first splicing member 21 and the second splicing member 22 are in a splicing state, the clamping hook 2311 is clamped and matched with the clamping piece 2312; when the first splicing member 21 and the second splicing member 22 are in the non-spliced state, the hook 2311 is separated from the clamping piece 2312.
