[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] Embodiment 1: refer to Figures 1 to 14 An assembled building enclosure includes a frame 1 having a plurality of nodes 11, and an assembly unit 2, which is configured with a plurality of units, which are respectively installed on the frame 1. The assembly unit 2 is composed of a main enclosure unit 21 and a plurality of slave enclosure units 22, wherein the main enclosure unit 21 is arranged on the node 11, and the plurality of slave enclosure units 22 are arranged on the periphery of the main enclosure unit 21.

[0024] It should be explained that dividing an assembly unit 2 into a main enclosure unit 21 and multiple slave enclosure units 22 allows only one main enclosure unit 21 or one slave enclosure unit 22 to be carried each time, thereby reducing the weight that workers have to carry each time and thus reducing the difficulty of assembly.

[0025] As a preferred embodiment, the enclosure main unit 21 and the enclosure slave unit 22 both include a composite panel 3, which is composed of an insulation panel 31, a sound insulation panel 32, a heat reflection panel 33 and a decorative panel 34 from the inside to the outside; wherein the insulation panel 31, the sound insulation panel 32 and the heat reflection panel 33 are assembled and fixed in sequence with bolts and nuts, and a plurality of pressure regulating components 4 are arranged circumferentially between the decorative panel 34 and the heat reflection panel 33.

[0026] It should be explained that the four sides of the heat reflecting plate 33 are provided with heat insulation films, that is, when two heat reflecting plates 33 are spliced, a gap between the two heat reflecting plates 33 is avoided, thereby preventing poor insulation effect. At the same time, the heat reflecting plate 33 can be used as an isolation zone to prevent external interference from entering the building.

[0027] As a preferred embodiment, the enclosure main unit 21 also includes a positioning block 211, a trapezoidal slider 212, a compression spring 213, an insertion block 214 and a pressing block 215; the positioning block 211 is fixedly assembled on the node 11 by bolts and nuts, a rectangular groove is provided in the positioning block 211, and four sides of the rectangular groove are provided with sliding grooves inwardly, four trapezoidal sliders 212 are arranged on the circumference, and are respectively slidably set in the sliding grooves, four compression springs 213 are arranged on the circumference, and are respectively connected between the trapezoidal slider 212 and the inner wall of the sliding groove, the insertion block 214 is fixed on the end of the insulation board 31 away from the sound insulation board 32, four pressing blocks 215 are arranged on the circumference, and their cross-sections are right-angled triangles, the right-angled sides of the pressing blocks 215 are fixed on the insertion blocks 214, and the insertion blocks 214 are slidably set in the rectangular grooves.

[0028] For details, please refer to Figure 4 By pressing the composite plate 3, the insertion block 214 moves downward with the pressing block 215, and the inclined surface of the pressing block 215 squeezes the inclined surface of the trapezoidal slider 212, so that the trapezoidal slider 212 moves into the slide groove. When the pressing block 215 is completely located below the trapezoidal slider 212, under the elastic force of the compression spring 213, the trapezoidal slider 212 moves to the upper end surface of the pressing block 215, thereby limiting the movement of the pressing block 215, that is, completing the fixed assembly of the enclosure main unit 21.

[0029] As a preferred embodiment, insertion holes 321 are opened inward on all four sides of the sound insulation plate 32, and a group of two adjacent insertion holes 321 of one sound insulation plate 32 are respectively connected with a trapezoidal slider 2 322 through a return spring, and the two trapezoidal sliders 2 322 are respectively slidably set in the two insertion holes 321 of an adjacent sound insulation plate 32.

[0030] In detail, after the assembly of the enclosure main unit 21 is completed, multiple enclosure slave units 22 are installed in the enclosure main unit 21 in sequence. Specifically, the placement angle of the composite panel 3 is adjusted first, and the composite panel 3 is pressed so that the trapezoidal slider 2 322 in the enclosure main unit 21 completely enters the insertion hole 321 of an adjacent enclosure slave unit 22. This completes the assembly of the enclosure slave unit 22. Similarly, the remaining enclosure slave units 22 are assembled in sequence according to the above process to complete the installation of the entire assembly unit 2. In this process, the assembly can be completed by only pressing, thereby speeding up the installation speed and reducing the difficulty of assembly.

[0031] As a preferred embodiment, the pressure regulating assembly 4 includes a limiting cylinder 41, a T-shaped column 42, a sliding column 43, a spherical head 44, and a damping spring 45; the limiting cylinder 41 is fixed to one end of the decorative panel 34 close to the heat reflecting plate 33, one end of the T-shaped column 42 is rotatably arranged in the limiting cylinder 41, and the other end passes through the limiting cylinder 41, and the end of the T-shaped column 42 away from the limiting cylinder 41 is provided with a limiting groove 421 inwardly along the outer wall, the sliding column 43 is slidably arranged in the limiting groove 421, the spherical head 44 is fixed to one end of the sliding column 43 close to the outer wall of the T-shaped column 42, and the damping spring 45 is connected between the inner wall of the limiting groove 421 and the sliding column 43.

[0032] As a preferred embodiment, the pressure regulating assembly 4 also includes a cylindrical groove 46, which is opened in the heat reflecting plate 33 and is located on the side close to the decorative plate 34, and the cylindrical groove 46 is coaxially arranged with the T-shaped column 42, and the T-shaped column 42 is slidably arranged in the cylindrical groove 46, and a U-shaped guide groove 47 is also opened inward on the inner wall of the cylindrical groove 46, and the cross-sectional radius of the U-shaped guide groove 47 is equal to the radius of the spherical head 44, and the spherical head 44 is slidably arranged in the U-shaped guide groove 47, and the starting end and the terminal end of the U-shaped guide groove 47 are both arranged on an end face of the heat reflecting plate 33 close to the decorative plate 34, and a card groove 1 48 and a card groove 2 49 are respectively opened inward on the inner wall of the U-shaped guide groove 47.

[0033] For details, please refer to Figures 7 to 11 When assembling the decorative panel 34, first press the decorative panel 34, move the spherical head 44 to place it in the U-shaped guide groove 47, so that the T-shaped column 42 completely enters the columnar groove 46, continue to press the decorative panel 34, so that the spherical head 44 moves to the position of the card slot 48, and the spherical head 44 will sink into the card slot 48 under the elastic force of the damping spring 45, thereby completing the assembly of the decorative panel 34.

[0034] As a preferred embodiment, the distance between the first clamping slot 48 and the starting end of the U-shaped guide slot 47 is greater than the distance between the second clamping slot 49 and the starting end of the U-shaped guide slot 47 .

[0035] It should be noted here that the depth of the first slot 48 and the second slot 49 is smaller than the radius of the spherical head 44 , that is, the first slot 48 and the second slot 49 cannot completely limit the spherical head 44 .

[0036] For details, please refer to Figures 6 to 11 When a bird in the air hits a certain enclosure unit, the decorative plate 34 of the enclosure unit will be damaged by the impact. At this time, the decorative plate 34 is subjected to a certain pressure, which will overcome the damping force of the slot 1 48 on the spherical head 44. After that, under the inertia of the decorative plate 34, the spherical head 44 will continue to move along the U-shaped guide groove 47. For details, please refer to Figure 10 to Figure 11When the spherical head 44 moves to the arc portion, due to the inertia of the spherical head 44, the spherical head 44 will perform centrifugal motion along the arc portion. During the centrifugal motion of the spherical head 44, since the spherical head 44 rotates a certain angle relative to the cylindrical groove 46, the spherical head 44 will drive the T-shaped column 42 to rotate a certain angle synchronously. After the spherical head 44 completes the movement of the arc portion, it still has a certain speed, so the spherical head 44 continues to move along the U-shaped guide groove 47. When the spherical head 44 moves to the position of the second card groove 49, the speed of the spherical head 44 is reduced to zero. Since the distance between the first card groove 48 and the starting end of the U-shaped guide groove 47 is greater than the distance between the second card groove 49 and the starting end of the U-shaped guide groove 47, please refer to Fig.12 , the decorative panel 34 will move from the first state to the second state, that is, the impacted decorative panel 34 will protrude from the overall plane. On the one hand, its position is not consistent with the horizontal plane of the other decorative panels 34, and the position of the reflected sunlight is different from the original position, so that it can be more easily discovered and can be repaired in time; on the other hand, the worker only needs to pull the protruding decorative panel 34 to pull out the spherical head 44 trapped in the second slot 49, that is, to complete the removal of the decorative panel 34, thereby avoiding the removal of the remaining enclosure panels associated with the decorative panel 34, thereby avoiding waste of resources and making the replacement of the decorative panel more convenient.

[0037] As a preferred embodiment, the depth of the first card slot 48 is smaller than the depth of the second card slot 49 .

[0038] That is, when the spherical head 44 moves into the second slot 49 , the spherical head 44 will sink into the second slot 49 , preventing the spherical head 44 from rushing out of the second slot 49 and preventing the decorative panel 34 from falling from a high altitude.

[0039] Embodiment 2: As a preferred embodiment, the decorative panel 34 includes an installation box 341, a micro projector 342, a screen 343, a rotating shaft 344 and a protective sheet 345; the installation box 341 is a coverless box body, the installation box 341 is fixedly connected to a plurality of limiting cylinders 41, the micro projector 342 is fixedly installed at the bottom center of the installation box 341, the screen 343 is fixedly installed at the upper end of the installation box 341, a plurality of through holes are opened on the circumference of the bottom of the installation box 341, and the plurality of through holes are respectively coaxially arranged with a plurality of T-shaped columns 42, a plurality of rotating shafts 344 are arranged on the circumference, respectively penetrate the plurality of through holes and are respectively fixed to the upper ends of the plurality of T-shaped columns 42, a plurality of protective sheets 345 are arranged on the circumference, respectively fixed to the upper ends of a plurality of rotating shafts 344, and the heights of the plurality of protective sheets 345 in the vertical direction are in an increasing manner.

[0040] It should be noted that the micro projector 342 is electrically connected to an external control terminal so as to project images onto the screen 343 for nighttime display.

[0041] Specifically, when the spherical head 44 drives the T-shaped column 42 to rotate, please refer to Figure 13 to Figure 14 , multiple rotating shafts 344 will drive multiple protective sheets 345 to rotate. It should be noted here that the arc portion of the U-shaped guide groove 47 corresponds to a rotation angle of 90°, that is, when the screen 343 is not hit, the multiple protective sheets 345 are at the edge of the installation box 341, and the micro-projector 342 can perform normal projection without obstruction. When the screen 343 is hit, the multiple T-shaped columns 42 will drive the multiple protective sheets 345 to rotate 90°, so that the distal ends of the multiple protective sheets 345 overlap each other above the micro-projector 342. Therefore, on the one hand, the multiple protective sheets 345 can shield the micro-projector 342. Therefore, at night, this screen 343 will completely turn black, forming a clear contrast with other normally luminous screens 343, so that it is easier to be discovered. On the other hand, the multiple overlapping protective sheets 345 can prevent the fragments of the impacted screen 343 from causing damage to the micro-projector 342 and other equipment inside the installation box 341.

[0042] The preparation method of the present invention is as follows: S1: First, the heat insulation board 31, the sound insulation board 32 and the heat reflection board 33 are installed in sequence by bolts and nuts, and then the decorative board 34 is installed in the columnar groove 46 through the T-shaped column 42, and the ball head 44 is sunk into the card slot 1 48, and the multiple protective sheets 345 are respectively located at the edge of the installation box 341, so that the multiple composite panels 3 are assembled; S2: Install the positioning block 211 at the node 11 by means of bolts and nuts, and fix the composite plate 3 in the positioning block 211 by pressing the main enclosure unit 21; S3: After the main enclosure unit 21 is assembled, multiple secondary enclosure units 22 are assembled by pressing on the periphery of the main enclosure unit 21, thereby completing the installation of one assembly unit 2; S4: Thereafter, the next assembly unit 2 is installed in the same manner as S2 and S3.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
