Referring to fig. 1 and 2, according to an embodiment of the first aspect of the present invention, a display screen module 100 with an arc includes a box body 110, at least two lamp panels 140, and a fastening portion 150, wherein at least one group of first supporting portions 120 and one group of second supporting portions 130 are disposed on a mounting surface 111 of the box body 110, and an included angle DD different from 180 degrees is formed between the first supporting portions 120 and the second supporting portions 130; the lamp panel 140 is supported to the first and

second support parts

120 and 130, respectively; fastening portion 150 is provided between case 110 and lamp panel 140, and fixes lamp panel 140 to mounting surface 111.

In this embodiment, because first supporting part 120 and second supporting part 130 that have the contained angle of non-180 degrees are set up on the installation face 111 of box 110, and first supporting part 120 and second supporting part 130 support different lamp plates 140 respectively, because after lamp plate 140 is fixed to installation face 111, with the contained angle between first supporting part 120 and the second supporting part 130 unanimous, also have the contained angle of non-180 degrees, consequently, the whole radian that has of the display screen of single box 110, when splicing into splicing screen 200 with the display screen of single box 110, then can enlarge the whole radian of splicing screen 200. Therefore, when the field is narrow and the number of the spliced box bodies 110 is limited, the radian of the spliced screen 200 can be obviously sensed, and the spliced screen is good in using effect and more attractive.

In this embodiment, it is conceivable that the included angle other than 180 degrees may be an included angle smaller than 180 degrees, at which the radian of the single display screen module 100 is an inner arc, or an included angle larger than 180 degrees, at which the radian of the single display screen module 100 is an outer arc. Here, the mounting surface of the case is a surface (i.e., a front surface) on which the lamp panel is mounted, and is opposed to a surface (i.e., a rear surface) on which other components such as a power supply are mounted.

Referring to fig. 3 and 4 with continued reference to fig. 2, specifically, in some embodiments, the first supporting portion 120 is located at one side of the box body 110, and includes a plurality of first supporting blocks 121, and each first supporting block 121 is provided with a first supporting inclined surface 122 for supporting one of the lamp panels 140; the second supporting portion 130 is located at the other side of the box body 110, and includes a plurality of second supporting blocks 131, and each second supporting block 131 is provided with a second supporting inclined plane 132 for supporting another one of the lamp panels 140; the first support ramp 122 and the second support ramp 132 have an included angle DD that is not 180 degrees therebetween. Through set up first supporting inclined plane 122, set up second supporting inclined plane 132 on second supporting shoe 131 on first supporting shoe 121 respectively, can conveniently realize the contained angle DD between the different lamp plates 140.

It is conceivable that the first supporting blocks 121 are distributed at different positions toward the left side of the box body 110 from a middle position in the left-right direction of the box body 110 to support one of the lamp panels 140 at multiple points. The second supporting blocks 131 are distributed at different positions from the middle position of the left and right directions of the case 110 toward the right side of the case 110 to support another lamp panel 140 at multiple points. The

inclined surfaces

122 and 132 of the supporting

blocks

121 and 131 may be directly formed on the case 110, for example, directly formed by a CNC machine, or may be formed by mounting an adjusting plate having an inclined surface on each supporting block.

It is also conceivable that the heights of the inclined surfaces of the support blocks of the same group are not completely uniform. For example, when the arc of the display panel module 100 is required to be an inner arc, the height of each first supporting slope 122 gradually increases from the middle position in the left-right direction of the cabinet 110 toward the left side of the cabinet 110, and the height of each second supporting slope 132 gradually increases from the middle position in the left-right direction of the cabinet 110 toward the right side of the cabinet 110, so that the lamp panel 140 is supported by the first supporting portion 120 and the second supporting portion 130, respectively, and then the whole is formed into an inner arc. The increasing trend of the first supporting inclined plane 122 may be the same as the increasing trend of the second supporting inclined plane 132, so that the two lamp panels 140 located at both sides of the left and right direction of the box body 110 are symmetrical with respect to the middle position of the left and right direction of the box body 110. Here, although the description has been given of the case where two lamp panels 140 are attached to the attachment surface 111 of one housing 110 in the present embodiment, the present invention is not limited to this, and a plurality of lamp panels 140 may be attached to the attachment surface 111 of one housing 110, and correspondingly, a plurality of sets of the first support unit 120 and the second support unit 130 may be provided.

In some embodiments, an included angle DD between the lamp panel 140 supported by the first support 120 and the lamp panel 140 supported by the second support 130 is greater than or equal to 170 degrees and less than 180 degrees. Therefore, the inner arc of one box body 110 can be in a reasonable range, and the display effect is better. Of course, the included angle DD between different lamp panels 140 may also be changed by changing the angle of each first supporting inclined surface 122 and the angle of each second supporting inclined surface 132.

In some embodiments, the inner portions 140a of one lamp panel 140 are flush with the inner portions 140b of the other lamp panel 140 adjacent thereto; the outer sides 140c of the lamp panels 140 are flush with the outer sides 110a of the adjacent cases 110. From this, not only can reduce the clearance between the lamp plate 140 on same display screen module 100, clearance between the lamp plate 140 when can also reducing the concatenation between the different display screen modules 100 to obtain better display effect. It is conceivable that, in consideration of the difference in actual size of each lamp panel 140, the two lamp panels 140 are flush with each other, and are not limited to being tightly attached as long as they can be as close as possible.

Referring to fig. 5 with continued reference to fig. 2, in some embodiments, in order to enable the fastening part 150 to be adaptive according to an angle at which the lamp panel 140 is supported, the fastening part 150 includes a plurality of parts, each of which floatingly fastens the lamp panel 140 to the cabinet 110. For example, the fastening parts 150 are respectively disposed beside the first and second supporting

blocks

121 and 131 to floatingly fasten the lamp panel 140 to the case 110.

In some embodiments, the fastening part 150 includes a fastening member 151, the fastening member 151 is constrained to the case 110, an upper end 151a of the fastening member 151 is fastened to the lamp panel 140, a lower end 151b of the fastening member 151 is provided with a connecting block 152 having an arc shape, for example, the fastening member 151 has a substantially cylindrical shape, the connecting block 152 has a substantially spherical shape, and the fastening member 151 and the connecting block 152 are integrally formed. The fastener 151 is supported to the case 110 by the connection block 152. Since the fastening member 151 is supported to the case 110 by the arc-shaped connecting block 152, when the angle and/or height of the lamp panel 140 fastened by the fastening portion 150 are different, for example, when the lamp panel 140 is installed in an inner arc, the height of the fastening portion 150 located at the middle position in the left-right direction of the case 110 is lower than the height of the fastening portions 150 located at both side portions in the left-right direction of the case 110, and the fastening member 151 can adaptively adjust, for example, adaptively tilt (for example, adaptively adjust the tilt angle EE) according to the arc-shaped connecting block 152 to adapt to different fastening heights.

In some embodiments, to more conveniently fasten the lamp panel 140, the upper end 151a of the fastening member 151 fastens the lamp panel 140 by the magnetic member 156. Specifically, a magnetic steel column or a magnet may be disposed at an upper end 151a of the fastening member 151, and correspondingly, the lower portion of the lamp panel 140 is provided with a part such as an iron sheet 141, which can be attracted by the magnetic steel column or the magnet, so that the lamp panel 140 is conveniently fastened and adaptively adjusted according to an angle of the lamp panel 140.

In some embodiments, in order to increase the adjustment range of the fastening portion 150, the fastening portion 150 further includes an elastic member 153, and the elastic member 153 is disposed under the fastening member 151, supporting the connection block 152. Since the elastic member 153 can be compressed adaptively according to the fastening height of the lamp panel 140 or swing adaptively, the adjustment range of the fastening part 150 can be greatly increased. The elastic member 153 may be selected from a compression spring, a silicon rubber having a large compressibility, a rubber, etc., and is preferably a compression spring.

In some embodiments, in order to stabilize the adaptive adjustment of the fastening portion 150, a floating block 154 is disposed between the elastic member 153 and the connection block 152, an upper portion of the floating block 154 is provided with a first receiving groove 155 receiving the connection block 152, a receiving space of the first receiving groove 155 is slightly larger than the connection block 152, and a lower portion of the floating block 154 is supported to the elastic member 153. This can prevent the connecting block 152 from floating too much on the case 110, which may cause unstable support of the lamp panel 140. The lower portion of the slider 154 may be provided in a planar shape so that the elastic member 153 can stably support the slider 154.

In some embodiments, a second receiving groove 112 (refer to fig. 4) may be disposed on the mounting surface 111 of the box body 110, and a lower portion of the fastening portion 150 is received in the second receiving groove 112. Specifically, the elastic member 153 of the fastening portion 150, the floating block 154, and the connection block 152 integrally formed with the fastening member 151 are received into the second receiving groove 112. In order to limit the fastening member 151 within the case 110, the second receiving groove 112 is covered by the cover plate 157, the fastening member 151 passes through the avoiding hole 158 of the cover plate 157 and is exposed outside the second receiving groove 112, and a gap exists between the avoiding hole 158 and the fastening member 151, which allows the connecting block 152 to swing with respect to the first receiving groove 155, so that the fastening portion 150 can floatingly fasten the lamp panel 140 to the case 110.

The structure of the fastening portion 150 is not limited to the above structure, and for example, a ball-shaped floating joint, such as a commercially available ball-shaped floating joint applied to a pneumatic actuator (e.g., a pneumatic cylinder), may be used as the fastening portion 150, and a magnetic member may be provided on the ball-shaped floating joint to floatingly fasten the lamp panel 140 to the case 110.

According to the second embodiment of the present invention, the tiled display screen 200 is formed by at least two of the display screen modules 100 with curvature of the above embodiments.

In this embodiment, since the tiled screen 200 is formed by at least two display screen modules 100 with a radian by tiling, and since the display screen of the display screen module 100 formed by tiling the lamp panel 140 has a radian, the side surface of each display screen module 100 (the side surface of the box 110) can be a plane and is tiled by the existing well-known tiled structure. Even when the field is narrow and the number of the spliced box bodies 110 is limited, the radian of the spliced screen 200 can be obviously sensed, and the use effect is good and more attractive.

Further, the side surfaces of the display panel modules 100 (the side surfaces of the box body 110) may be inclined surfaces, and the entire arc of the joined panel 200 may be further expanded by joining the display panel modules by a conventional known arc joining structure (for example, an angle lock with an angle joint).

The various features described in the foregoing detailed description may be combined in any manner and, for the sake of unnecessary repetition, various combinations are not intended to be encompassed by the invention.

The above embodiments are merely illustrative of the technical solutions of the present invention and are not restrictive, and any modifications or equivalent substitutions which do not depart from the scope of the present invention should be included in the technical solutions of the present invention.
