DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 2~Figure 8As shown in the figure, this embodiment proposes a sand table, whose structure includes a fixed seat 1. In this embodiment, the sand table body 4 is rotatably arranged on the fixed seat 1, and is used to more accurately approach the actual daylighting situation by rotating the sand table body 4. The lighting module is arranged above the sand table body 4. The installation guide rail 3 is arranged on the lighting module, and the irradiation situation of sunlight during a day is simulated through the installation guide rail 3. The lighting module is slidably connected to the installation guide rail 3. The first control structure is arranged on the lighting module and is used to control the movement of the lighting module relative to the installation guide rail 3. The installation guide rail 3 is slidably connected to the fixed seat 1. The second control structure is arranged on the fixed seat 1 and is used to control the movement of the installation guide rail 3. The light-shielding strip 321 is fixedly arranged on the installation guide rail 3, and the light-shielding strip 321 is arranged at the lower end of the lighting module. In this embodiment, the light-shielding strip 321 is used to adjust the hue, lightness and saturation of the light emitted by the lighting module, so as to simulate the real sunlight irradiation.

[0023] Currently, when home buyers choose a building, the daylighting situation has become an important reference index. However, the existing sand table models cannot accurately reproduce the daylighting situations at different positions, floors and time periods of the building. For this reason, this embodiment proposes an optimization scheme, which can more accurately simulate the daylighting effects of the building at different positions and time periods.

[0024] The installation guide rail 3 in this embodiment is of an arc structure, and this arc structure is closer to the irradiation situation of real sunlight on the building. The lighting module includes an installation frame 6. The installation frame 6 is of a "U" - shaped structure and is used to facilitate the installation of the lighting lamp 62. The lighting lamp 62 is fixedly arranged at the bottom of the installation frame 6, and a sliding groove 63 is arranged at the top of the installation frame 6. The sliding groove 63 is slidably connected to the installation guide rail 3, and the cross - section of the sliding groove 63 is of a "convex" - shaped structure. Such a design of the sliding groove 63 ensures that the movement of the installation frame 6 is more stable and no deviation phenomenon will occur.

[0025] The first control structure in this embodiment includes an adjusting gear 61. A rack 33 is arranged on the side of the installation guide rail 3 close to the lighting module. The adjusting gear 61 is rotatably connected to the installation frame 6, and the adjusting gear 61 meshes with the rack 33. In this embodiment, the movement of the lighting module is realized by rotating the adjusting gear 61, so that the lighting module simulates the lighting situation of a day.

[0026] In this embodiment, the first sliding rail 71 and the second sliding rail 72 are arranged at the bottom of the mounting frame 6, the first sliding block 711 is slidingly arranged in the first sliding rail 71, the second sliding block 721 is slidingly arranged in the second sliding rail 72, the rotating shaft 611 is fixedly arranged on the adjusting gear 61, and the two ends of the rotating shaft 611 are respectively rotatably connected with the first sliding block 711 and the second sliding block 721, the first sliding block 711 and the second sliding block 721 are both rectangular structures, the first screw rod 712 is rotatably arranged in the first sliding rail 71, the first screw rod 712 is threadedly connected with the first sliding block 711, and the adjusting bolt 713 is arranged on the mounting frame 6, and the adjusting bolt 713 is fixedly connected with the first screw rod 712. When the illumination module is used for a long time, it may cause the adjusting gear 61 to be not tightly engaged with the rack 33. By controlling the first screw rod 712 to control the adjusting gear 61 to approach the rack 33, it is ensured that even if the adjusting gear 61 and the rack 33 are more tightly engaged. Such a design can make the installation of the adjustment gear 61 more convenient.

[0027] The first drive motor 612 in this embodiment is fixedly arranged on the first sliding block 711, and the output shaft of the first drive motor 612 is fixedly connected to the rotating shaft 611. The first drive motor 612 used in this embodiment is a two-phase motor. The user can control the forward and reverse rotation of the first drive motor 612 to control the movement of the illumination module relative to the mounting guide rail 3, and the user control is more automated and convenient. In this embodiment, a turbine 81 can be set on the output shaft of the first drive motor 612, and a worm 41 can be set on the rotating shaft 611, and the worm 41 can be driven by the turbine 81 to realize the first drive motor 612 to control the movement of the illumination module. In this way, even if the first drive motor 612 is in a power-off state, it is difficult for the worm 41 to reversely drive the turbine 81 to rotate, and the illumination module can be ensured to hover above the sand table body 4.

[0028] The light shielding shell 31 in this embodiment is fixedly arranged on the mounting rail 3 to prevent the light emitted by the illumination lamp 62 from spilling out, and to ensure that the light emitted by the illumination lamp 62 is closer to the actual sunlight. The rack 33 is placed in the light shielding shell 31, the sealing plate 32 is arranged on the side of the light shielding shell 31 close to the sandbox body 4, the mounting notch 322 is arranged on the side of the sealing plate 32 close to the illumination module, and the light shielding strip 321 is fixedly arranged on the mounting notch 322. In this embodiment, the sealing plate 32 can be fixed to the light shielding shell 31 body by bolts, which is convenient for the disassembly of the sealing plate 32 relative to the light shielding shell 31 body, and convenient for the user to open the light shielding shell 31 for maintenance and disassembly of the illumination module.

[0029] In this embodiment, the two ends of the shading strip 321 are made of golden material, and the center of the shading strip 321 is made of transparent material. The color of the shading strip 321 changes gradually from the two ends to the center, and the saturation and brightness gradually decrease. The illumination module emits light at the two ends of the shading strip 321 to simulate the sunrise and sunset of the day, and the center of the shading strip 321 simulates noon of the day. The transparent material used in the center of the shading strip 321 makes the sunlight irradiated by the illumination module on the sand table body 4 brighter, corresponding to the actual noon sunlight exposure.

[0030] In this embodiment, the second drive motor 8 is fixedly arranged in the fixing seat 1, the turbine 81 is fixedly arranged on the output shaft of the second drive motor 8, the worm 41 is fixedly arranged at the bottom of the sand table body 4, the turbine 81 and the worm 41 are meshed, the rotation groove 13 is arranged on the fixing seat 1, the rotation groove 13 is a cylindrical structure, and the sand table body 4 is arranged in the rotation groove 13. Since the worm 41 is controlled by the turbine 81 to control the rotation of the sand table body 4, when the second drive motor 8 loses power and does not work, since the worm 41 cannot reversely drive the turbine 81 to rotate, the sand table body 4 is difficult to rotate, thereby preventing the user from accidentally changing the rotation angle of the sand table body 4.

[0031] In this embodiment, the first placement groove 11 and the second placement groove 12 are arranged on both sides of the fixed seat 1, and the second screw rod 111 and the third screw rod 121 are respectively rotated in the first placement groove 11 and the second placement groove 12, and a synchronous belt 123 is connected between the second screw rod 111 and the third screw rod 121. In this embodiment, a connecting groove can be set between the first placement groove 11 and the second placement groove 12, and the synchronous belt 123 is set in the connecting groove. The third sliding block 112 and the fourth sliding block 122 are fixedly arranged at both ends of the mounting rail 3, the first screw rod 712 is threadedly connected to the third sliding block 112, and the second screw rod 111 is threadedly connected to the fourth sliding block 122. The movement of the mounting rail 3 is controlled by the second screw rod 111 and the third screw rod 121. Since the rotation stroke of the second screw rod 111 and the third screw rod 121 is much greater than the movement stroke of the illumination module, the movement of the illumination module is controlled more accurately and reliably by the second screw rod 111 and the third screw rod 121.

[0032] In this embodiment, the first protective cover 21 and the second protective cover 22 are arranged on the fixed seat 1, and the first protective cover 21 and the second protective cover 22 are rotatably connected to the fixed seat 1. The first protective cover 21 and the second protective cover 22 are both spherical structures, and the first protective cover 21 and the second protective cover 22 are both made of transparent materials. The first connecting structure is arranged between the first protective cover 21 and the fixed seat 1, and is used to connect, fix or separate the first protective cover 21 and the fixed seat 1. The second connecting structure is arranged between the second protective cover 22 and the fixed seat 1, and is used to connect, fix or separate the second protective cover 22 and the fixed seat 1. The first connection structure includes a limit block 5, a limit groove 14 is arranged on one side of the fixed seat 1, a fifth sliding block 51 is fixedly arranged on the limit block 5, the fifth sliding block 51 is slidingly connected with the limit groove 14, a limit spring 141 is arranged in the limit groove 14, one end of the limit spring 141 is fixedly connected with the limit groove 14, and the other end of the limit spring 141 is fixedly connected with the fifth sliding block 51, so as to ensure that the limit block 5 always maintains an extended state, so as to facilitate the connection with the first protective cover 21. The clamping hole 211 is arranged on the first protective cover 21, and the limit block 5 is a right-angled trapezoidal structure, so as to facilitate the clamping block 5 to be clamped into the clamping hole 211 on the first protective cover 21. The structure of the second connection structure is the same as that of the first connection structure. When the first protective cover 21 rotates and approaches the limit block 5, due to the effect of the inclined surface on the limit block 5, the first protective cover 21 pushes the limit block 5 to retract until the clamping hole 211 on the first protective cover 21 is aligned with the limit block 5. Under the effect of the limit block 5, the first protective cover 21 is stuck and cannot rotate, thereby protecting the model in the sandbox from external influences. When the sandbox body 4 needs to be opened, the limit block 5 can be pushed to retract, and then the first protective cover 21 can be rotated to open the sandbox, which is convenient for adjusting the model inside the sandbox.

[0033] The working process of this embodiment is as follows: first fix the building model on the sand table body 4, then drive the synchronous belt 123 according to the actual position of the building and the sun, so that the sand table body 4 and the building model reach a suitable eccentric position, then start the first drive motor 612, so that the irradiation angle of sunlight and the building model matches the actual irradiation angle of sunlight and the building, and then start the second drive motor 8 to make the lighting module move relative to the mounting guide rail 3, and the lighting lamp 62 irradiates the building model through the shading strip 321, so as to simulate the sunlight irradiation angle at various positions of the building at different times of the day.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
