Description

Technical Field

[0001] The present invention relates to the technical field of economic analysis, and in particular to an economic analysis device for economic management and finance. Background Art

[0002] In the research and teaching of modern economic management and finance, simulating real-world market activities is essential for training professionals. Although traditional theoretical teaching and case studies can provide a certain knowledge base, they are limited in practical application ability and intuitive understanding. With the advancement of science and technology, sandbox simulation systems that combine physical models with digital displays have gradually become an important tool for economic management education and financial economic analysis. These systems provide students and researchers with a learning platform that is closer to actual operations by simulating various factors in the real market environment, such as monetary policy, fiscal policy, market supply and demand, etc. In addition, the sandbox simulation system can also display data changes in real time, allowing users to have a deeper understanding of complex economic phenomena and to think and make strategic decisions.

[0003] However, most of the existing economic analysis equipment is mainly static display, lacking interactivity and flexibility, and cannot fully meet the needs of dynamic economic analysis. Especially in large-scale team collaboration or public display scenarios, single-view displays make it difficult to ensure that all participants can clearly observe the analysis results, limiting the effectiveness of communication and discussion. In addition, since such equipment is usually large in size and inconvenient to move, it is easy to cause damage when transferred between different venues. Summary of the invention

DETAILED DESCRIPTION

[0032] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0033] Embodiment 1: An economic analysis device for economic management and finance, such as Figure 1-3As shown, it includes a sandbox 1, a base 2, a connecting line 3, a support frame 4, a fixed display 5, an active display 6, casters 7, an active bracket 8, a support mechanism 10 and a pressing mechanism 11. A touch screen is provided on the top of the sandbox 1 to demonstrate interactive contents such as economic models, financial market dynamics, and policy simulation effects. It can not only display static data and charts, but also simulate different economic scenarios through user interaction, such as monetary policy adjustments, fiscal policy implementation, and changes in market supply and demand. In addition, the display supports multi-touch, allowing multiple students or researchers to operate at the same time to practice strategic thinking and decision-making. The sand table 1 is connected to the base 2 through a connecting line 3, which is responsible for transmitting power and data signals. The top of the base 2 is connected to a support frame 4, which is composed of two columns and a connecting piece (marked in the figure). The two columns are connected to the rear side of the top of the base 2, and the connecting piece is connected to the columns. A fixed display 5 is installed on the front side of the connecting piece of the support frame 4 through bolts. Both left and right sides of the fixed display 5 are provided with active displays 6, and the left active display 6 is arranged forward and the right active display 6 is arranged backward, so that the two active displays 6 can be recovered smoothly, and when recovered, the left active display 6 is located in front of the right active display 6. The base 2 is connected to the fixed display 5, the active display 6 and other electrical appliances through independent power lines and data lines. The images displayed on the sand table 1 can be displayed through three displays, namely, a fixed display 5 and two active displays 6. These displays can be used to display the content on the sand table 1 synchronously or separately, so as to provide different perspectives or detailed information for the audience. A guide groove 61 is horizontally provided at the bottom of the movable display 6, and shafts are provided at both ends of the movable display 6. The movable display 6 is rotatably connected to the connecting piece of the support frame 4 through the shaft. Casters 7 are installed at the bottom of the base 2. The casters 7 are universal wheels with braking function, which are convenient for moving the device. Movable brackets 8 are rotatably connected to the left and right sides of the top of the base 2. One side of the upper end of the movable bracket 8 is rotatably connected to the support frame 4, and the other side is movably connected to the guide groove 61 through a guide column 81. A pressing mechanism 11 is installed at the bottom of the base 2, and a supporting mechanism 10 is provided in the middle of the bottom of the base 2. The pressing mechanism 11 cooperates with the supporting mechanism 10.

[0034] like Fig.10 and 12 As shown, it also includes a driving motor 14. The driving motors 14 are installed on both sides of the top of the support frame 4. The driving motor 14 is connected to the movable bracket 8 through a worm gear transmission.

[0035] During the financial and economic analysis exercise, the operator uses the sandbox 1 as a tool. The sandbox 1 is electrically connected to the base 2 via a connecting line 3, which is responsible for transmitting power and data signals. The base 2 is connected to the fixed display 5, the active display 6 and other electrical appliances via independent power and data cables to ensure the power supply and effective signal transmission of all electrical appliances. This setting allows the activities on the sandbox 1 to be reflected on the display in real time and allows all related electronic devices to work together. The active display 6 is initially in a retracted state (such as Fig.10 As shown in the figure), when the active display 6 needs to be unfolded, the drive motor 14 is started, and the drive motor 14 on the left side is started to drive the active display 6 on the left side to rotate. The active display 6 on the left side drives the active bracket 8 to gradually unfold through the cooperation of the guide column 81 and the guide groove 61. When the rotation angle of the active display 6 on the left side is greater than 90 degrees, the active display 6 on the right side is unfolded in the same way. When the audience watches in front of the fixed display 5, the active display 6 is rotated and adjusted to an angle greater than 90 degrees and less than 180 degrees for viewing. When the audience watches around the base 2, the active displays 6 on both sides are continued to rotate to keep them away from one end of the support frame 4. The fixed display 5 and the two movable displays 6 are in contact with each other, forming a triangular structure, which is convenient for people around to watch. When the device needs to be folded up, the right drive motor 14 is started first to drive the right movable display 6 to reset, and then the left drive motor 14 is started to drive the left movable display 6 to reset. In this way, the two movable displays 6 can be retracted, the overall volume is reduced, and it is easy to carry. The display screens of the movable displays 6 face inwards to prevent possible damage during transportation. When the movable display 6 is unfolded, the movable bracket 8 thereon can play a supporting role to avoid deformation of the upper shaft rod of the movable display 6 due to force on the tail, thereby ensuring the service life of the device.

[0036] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 5 As shown, the pressing mechanism 11 includes a connecting rod 111, a guide block 112 and a connecting plate 114. Guide blocks 112 are slidably installed on both sides of the front and rear of the bottom of the base 2. The left ends of the two guide blocks 112 are connected by a connecting rod 111. A Z-shaped groove 113 is provided on the inner side of the guide block 112. A connecting plate 114 is provided between the Z-shaped grooves 113 on both sides. Round rods are provided at both ends of the connecting plate 114, and the round rods are located in the Z-shaped grooves 113.

[0037] like Figure 2 , Figure 4 and Figure 5As shown, the support mechanism 10 includes a spline shaft 101, a flared guide rail 102 and a support member 103. The spline shaft 101 is rotatably mounted in the middle of the connecting plate 114. The spline shaft 101 penetrates the base 2. The flared guide rail 102 is mounted at the bottom of the spline shaft 101. The flared guide rail 102 is located below the base 2. Both ends of the flared guide rail 102 are designed to gradually expand toward both sides so that the width of the two ends of the inner slideway is greater than the middle portion, forming a flared structure. The support member 103 is movably mounted on the flared guide rail 102.

[0038] like Figure 6-Figure 8 As shown, the support member 103 includes a slider 1031, a movable leg 1032, a support wheel 1033 and a torsion spring 1034. The slider 1031 is slidably installed in the slideway of the flared guide rail 102. Two movable legs 1032 are movably connected at both ends of the slider 1031. Support wheels 1033 are installed at the bottom of the four movable legs 1032. The top of the movable leg 1032 is in contact with the inner wall of the flared guide rail 102. A torsion spring 1034 is connected between the movable leg 1032 and the slider 1031.

[0039] When the movable display 6 is unfolded, the base 2 has a small force-bearing area and is prone to tilting and instability. Therefore, a supporting mechanism 10 and a pressing mechanism 11 are provided. When the supporting mechanism 10 is needed to support the device, the two guide blocks 112 are driven to move to the left by pulling the connecting rod 111. The guide blocks 112 move through the Z-shaped grooves 113 thereon to drive the connecting plate 114 to move downward. The spline shaft 101 and the flared guide rail 102 move downward accordingly. The supporting wheel 1033 moves downward to contact the ground to play a supporting role. Then the slider 1031 is pulled to move. The slider 1031 drives the movable leg 1032 to move. When the connection between the movable leg 1032 and the slider 1031 moves to the flared position of the flared guide rail 102, the torsion spring 1034 is engaged. The ends of the movable legs 1032 on both sides close to the supporting wheels 1033 are driven away from each other to expand the supporting area and prevent the device from tipping over. When the movable display 6 is retracted, the slider 1031 can be pulled to reset. The slider 1031 drives the movable legs 1032 to move from the flaring position of the flaring guide rail 102 to the middle. The movable legs 1032 are squeezed by the flaring guide rail 102 and move together, and the torsion spring 1034 is deformed. When the slider 1031 is located in the middle position of the flaring guide rail 102, the flaring guide rail 102 is rotated 90 degrees to make the length direction of the flaring guide rail 102 correspond to the length direction position of the base 2. The flaring guide rail 102 and the movable legs 1032 are stored at the bottom of the base 2, which saves space and keeps the appearance neat and beautiful.

[0040] like Figure 2 , Figure 4 and Figure 5As shown, it also includes a pushing mechanism 9, which includes a first gear 91, a first rack 92, a push rod 93, a P-shaped block 94, a guide sleeve 95, an arc rod 96 and a spring 97. The first gear 91 is installed on the outer side of the lower part of the left movable bracket 8, and a sliding sleeve is fixed on the left side of the base 2. The first rack 92 is slidably connected in the sliding sleeve. The first rack 92 is meshed with the first gear 91, and the first rack 92 is located on the front side of the first gear 91. The connecting rod 111 is connected to the top of the right end of the first rack 92, and the right end of the first rack 92 is connected to the push rod 93. The outer side of the spline shaft 101 is slidably connected. A p-shaped block 94 is provided, and the p-shaped block 94 is rotatably connected to the base 2 by a bearing connection. A guide sleeve 95 is installed at the top of the base 2. An arc rod 96 is slidably provided in the guide sleeve 95. The arc rod 96 is arranged around a circular path concentric with the spline shaft 101. One end of the arc rod 96 is connected to the p-shaped block 94. A spring 97 is sleeved on the outer side of the arc rod 96. The two ends of the spring 97 are respectively connected to the arc rod 96 and the guide sleeve 95. The push rod 93 is located on the left side of the p-shaped block 94. When the push rod 93 moves to the right, it pushes the p-shaped block 94 to rotate 90 degrees counterclockwise, and the spring 97 is compressed.

[0041] When the flared guide rail 102 and the movable leg 1032 are stored at the bottom of the base 2, the spring 97 is in a compressed state, and the push rod 93 presses the P-shaped block 94, so that the P-shaped block 94 cannot rotate. When the left movable bracket 8 rotates clockwise and unfolds, the first gear 91 is driven to rotate through its upper shaft rod, and the first gear 91 drives the first rack 92 to move to the left, and the first rack 92 drives the connecting rod 111 and the push rod 93 to move to the left. After the P-shaped block 94 is no longer pressed by the push rod 93, the spring 97 drives the P-shaped block 94 to rotate and reset, and the P-shaped block 94 drives the spline shaft 101 to rotate 90 degrees. The flared guide rail 102 then rotates 90 degrees to be perpendicular to the base 2, and in the process of the first rack 92 moving to the left, it drives the connecting rod 111 to move to the left, and drives the connecting plate 114 to move downward through the Z-groove 113 on the guide block 112. The connecting plate 114 moves downward and drives the flared guide rail 102 and the movable support leg 1032 downward through the spline shaft 101, and the support wheel 1033 contacts the ground to support the device. In this way, when the left active display 6 is opened, the movable support leg 1032 can be synchronously unfolded, and the support wheel 1033 can be moved down to contact the ground, which simplifies the operation steps.

[0042] like Figure 6 As shown, it also includes a driving mechanism 12, which includes a servo motor 121, a second gear 122 and a second rack 123. The servo motor 121 is installed at the bottom of the slider 1031, and the second gear 122 is connected to the output shaft of the servo motor 121 through a coupling. The second rack 123 is connected to the bottom of the flared guide rail 102, and the second gear 122 is located below the second rack 123, and the second gear 122 is meshed with the second rack 123.

[0043] When the slider 1031 needs to move on the flaring guide rail 102, the servo motor 121 is started to drive the second gear 122 to rotate. Under the action of the second rack 123, the servo motor 121, the gear and the slider 1031 move along the flaring guide rail 102. In this way, there is no need to manually pull the slider 1031, which further simplifies the operation steps.

[0044] Embodiment 3: Based on embodiment 2, Fig.11 and Fig.12 As shown, it also includes a protective mechanism 13, which includes a protective shell 131, a retaining ring 132, a telescopic sleeve 133 and an annular magnetic rod 134. The top of the support frame 4 is connected to the protective shell 131, and a retaining ring 132 is provided on the inner side of the protective shell 131. The retaining ring 132 divides the interior of the protective shell 131 into two inner and outer cavities. The telescopic sleeve 133 is installed on the outer cavity, and the bottom of the telescopic sleeve 133 is connected to the annular magnetic rod 134. The protective shell 131 and the base 2 are both made of materials that can generate attraction with the annular magnetic rod 134.

[0045] When the device is not in use, fold it up to the unfolded state (such as Fig.10 As shown), then, pull the annular magnetic rod 134 downward until it contacts the base 2. At this time, the annular magnetic rod 134 will be adsorbed on the base 2 due to magnetic force, so that the telescopic sleeve 133 will be unfolded as a whole and cover the outside of the display, forming a protective layer, providing dust and water protection, and preventing external environmental factors from damaging the display. When the device needs to be used again, push the annular magnetic rod 134 upward to overcome the magnetic force between it and the base 2, so that the annular magnetic rod 134 is detached from the base 2. Continue to pull the annular magnetic rod 134 upward, which will cause the telescopic sleeve 133 to gradually shrink and eventually retreat into the cavity between the retaining ring 132 and the outside of the protective shell 131. Finally, the annular magnetic rod 134 is adsorbed at a designated position on the protective shell 131 for fixation.

[0046] like Fig.13 and 14 As shown, it also includes a storage box 15 and an electric reel 16 . The storage box 15 is embedded in the left wall of the sand table 1 . The electric reel 16 is installed on the storage box 15 , and the connecting line 3 is wound around the electric reel 16 .

[0047] When adjusting the distance between the base 2 and the sand table 1, in order to ensure that the connecting wire 3 is neither too tight nor entangled, the electric reel 16 can be used to control the release and retraction of the connecting wire 3. This prevents the entanglement problem caused by the cable being too long, and ensures that the connecting wire 3 is always in the best working state, ensuring the stability and safety of power supply and data transmission.
