Description

Technical Field

[0001] This invention belongs to the field of power metering box technology, specifically relating to intelligent shared power metering boxes. Background Technology

[0002] With the rapid development of the sharing economy, smart shared power metering boxes, as key equipment for power supply and metering in public areas, are widely used in densely populated places such as shopping malls, stations, and scenic spots. These devices usually integrate coin payment functions and need to meet core requirements such as coin collection, security protection, and stable heat dissipation.

[0003] Existing shared power metering boxes require manual opening of the cabinet door and manual handling of the collection bin for coin collection. This process is cumbersome, labor-intensive, and carries the risk of exposure and damage to internal electrical components or unauthorized contact. Furthermore, the coin collection bins of traditional shared power metering boxes require manual removal and emptying of all collected coins, which is time-consuming, labor-intensive, and prone to coin residue and scattering, resulting in low coin collection efficiency and increased operating and maintenance costs. Additionally, the existing metering box door locking mechanisms are mostly independently configured mechanical or electronic locks, requiring additional drive components and control modules, leading to… The complex internal structure of the box increases manufacturing costs, while the poor compatibility between the independent lock and the main body of the box makes it prone to problems such as insecure locking and jamming when opening. The anti-theft performance is insufficient, and it is difficult to effectively prevent illegal opening of the box to steal coins or damage to internal electrical components. At the same time, the existing metering boxes integrate a large number of electronic components such as control panels and power switches, which continuously generate heat during operation. Most existing metering boxes use a single fan or natural convection through heat dissipation holes, without reasonable planning of airflow paths. Cold air cannot flow to the heat-generating components in a directional manner, and hot air is also difficult to expel quickly and in a concentrated manner, resulting in excessively high local temperatures inside the box. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an intelligent shared power metering box.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: an intelligent shared power metering box, including a power box body, a fixed compartment door hinged to one end of the back of the power box body, a display screen mounted on the top of the front of the power box body, a control panel and a power switch mounted from top to bottom on the side of the power box body away from the fixed compartment door, a coin acceptor mounted on the top of the side of the front of the power box body, with the coin outlet of the coin acceptor located inside the power box body, a coin collection mechanism for collecting coins located at the bottom of the power box body near the coin acceptor, a drive mechanism for providing power to the collection mechanism located inside the power box body near the fixed compartment door, a coin discharge mechanism for emptying the coins located inside the collection mechanism, a self-locking mechanism that cooperates with the drive mechanism located inside the fixed compartment door, and a heat dissipation mechanism for heat dissipation located inside the power box body.

[0006] Furthermore, the collecting mechanism includes a rectangular compartment located at the bottom of the power supply box near the coin acceptor. The bottom of the power supply box has a square through hole communicating with the bottom of the rectangular compartment. The rectangular compartment contains a collecting chamber for collecting coins, and the bottom of the collecting chamber near the display screen has a discharge outlet.

[0007] Through the above technical solution, the square-shaped bin provides installation and movement guidance space for the collection bin. Coins inserted by the coin acceptor fall directly into the collection bin for centralized collection. The square through hole at the bottom of the power supply box provides a channel for lifting and lowering the collection bin. The outlet at the bottom of the collection bin near the display screen serves as a channel for coin discharge. When the collection bin is moved to the appropriate position by the drive mechanism, the coins can be discharged through the outlet, solving the problem of traditional collection boxes requiring complete disassembly and coin emptying.

[0008] Furthermore, the drive mechanism includes threaded rods, of which two sets are provided, and the two sets of threaded rods are located inside the power supply box at one end near the fixed compartment door. The outer sides of the two sets of threaded rods are threaded with a first lifting plate. The two ends of the square-shaped compartment near the threaded rods are symmetrically provided with strip-shaped through holes. The two ends of the first lifting plate near the square-shaped compartment are symmetrically installed with connecting blocks, and the side of the connecting block away from the first lifting plate passes through the strip-shaped through hole and is fixedly connected to the outside of the collection compartment. A power component for driving the two sets of threaded rods to rotate is provided on one side of the square-shaped compartment.

[0009] Through the above technical solution, the power component provides driving force to drive the two sets of threaded rods to rotate synchronously. Since the first lifting plate is threadedly engaged with the two sets of threaded rods, the rotation of the threaded rods forces the first lifting plate to rise and fall along the axial direction of the threaded rods through threaded transmission. The first lifting plate drives the collection bin to rise and fall synchronously through the connecting blocks at both ends. The strip-shaped through hole provides guidance and clearance space for the movement of the connecting blocks, ensuring stable lifting and falling of the collection bin. There is no need for manual handling of the collection bin, which reduces the labor intensity of operation and maintenance, improves the convenience of coin recycling, and reduces the risk of manual contact with the components inside the box.

[0010] Furthermore, the power assembly includes a servo motor located at the bottom center of one side of the box-shaped compartment. The output shaft of the servo motor is equipped with a drive gear, and the bottom ends of the two sets of threaded rods are symmetrically equipped with driven gears that mesh with the drive gear.

[0011] Through the above technical solution, the servo motor drives the drive gear on the output shaft to rotate. Since the drive gear meshes with the driven gears at the bottom of the two sets of threaded rods, the rotation of the drive gear drives the two sets of driven gears to rotate synchronously through gear transmission, thereby realizing the synchronous and unidirectional rotation of the two sets of threaded rods, providing stable power for the lifting of the first lifting plate.

[0012] Furthermore, the discharge mechanism includes a first guide plate located at the bottom of the collection chamber. The bottom of the collection chamber at both ends, away from the discharge outlet, is symmetrically provided with strip-shaped channels. The first guide plate at both ends, away from the discharge outlet, is symmetrically equipped with a first rotating shaft that cooperates with the strip-shaped channels. A second guide plate is inserted into the side of the first rotating shaft near the discharge outlet, and the sides of the second guide plate near the discharge outlet are hinged to the inner ends of the discharge outlet via the second rotating shaft. Two sets of connecting rods are hinged to the top of the first guide plate at the side away from the discharge outlet, and the top ends of the two sets of connecting rods are fixedly connected to the top of the outer side of the square-shaped chamber.

[0013] Through the above technical solution, the coins in the collection bin are piled up on the first guide plate and the second guide plate. When the collection bin descends, the two sets of connecting rods hinged at the top are gradually stretched as the collection bin descends because their ends are fixedly connected to the collection bin and the square bin, respectively. This stretches the first guide plate around the second pivot. During the rotation, the first pivot moves upward in the strip groove, causing the second guide plate to gradually extend out from the first guide plate. When the collection bin descends to the point where the outlet is fully exposed, the first guide plate and the second guide plate form an inclined guide channel. Under the action of gravity, the coins pour out from the outlet along the guide channel, realizing the automatic centralized discharge of coins without disassembling the collection bin. This solves the problems of time-consuming and laborious coin emptying and easy scattering of coins in traditional collection boxes.

[0014] Furthermore, the self-locking mechanism includes two sets of fixed slots located inside the fixed compartment door. The top ends of the outer sides of the two sets of threaded rods are threaded with a second lifting plate. An L-shaped plug that matches the fixed slot is installed at the middle position of the top of the second lifting plate and the first lifting plate. The inlet end of the fixed slot faces downward.

[0015] With the above technical solution, when the fixed compartment door is closed, the threaded rod rotates, causing the first and second lifting plates to rise, so that the L-shaped blocks on the first and second lifting plates can be accurately inserted into the fixed slots inside the fixed compartment door, realizing the self-locking of the fixed compartment door. When it is necessary to open the compartment door, the threaded rod is controlled to rotate in the opposite direction, causing the first and second lifting plates to fall, the L-shaped blocks to disengage from the fixed slots, the self-locking is released, and the fixed compartment door can be opened. There is no need to configure an additional independent lock and drive component, which simplifies the internal structure of the box, reduces manufacturing costs, and effectively prevents illegal opening of the box to steal coins or damage to internal electrical components, thereby improving the anti-theft performance and security of the equipment.

[0016] Furthermore, the heat dissipation mechanism includes an intake fan located at the bottom of the power supply housing near the power switch. A guide component is provided at the bottom of the power supply housing near the intake fan. A collection chamber is symmetrically installed at the top of both ends of the power supply housing, and an air outlet is provided at the top of the collection chamber. An exhaust fan communicating with the inside of the collection chamber is symmetrically installed at the top of both ends of the power supply housing. The guide component includes a mounting bracket located above the intake fan, and several sets of air guide plates are evenly installed on the inner side of the mounting bracket.

[0017] The above technical solution utilizes an intake fan to introduce external cold air. This cold air is then directionally guided by several sets of air guides on the mounting bracket, precisely flowing towards core heat-generating components such as the control panel and power switch. The heated air, after absorbing heat, rises to the top of the enclosure and enters a collection chamber for centralized accumulation. Finally, the accumulated hot air enters the collection chamber through the exhaust port and is then discharged from the enclosure by the exhaust fan, forming a complete airflow circulation and heat dissipation channel. This solves the problems of chaotic airflow paths and uneven heat dissipation in traditional heat dissipation methods. Furthermore, the directional guidance of cold air to the heat-generating components by the air guides ensures highly targeted heat dissipation, while the concentrated accumulation and discharge of hot air results in high heat dissipation efficiency, effectively preventing excessively high local temperatures inside the enclosure that could lead to electronic component failure.

[0018] Furthermore, an outer groove is provided at the bottom of the inner side of the square through hole, and the diameter of the outer groove is larger than the diameter of the square through hole. An outer sealing plate that matches the outer groove is installed at the bottom of the collection chamber.

[0019] With the above technical solution, when the collection chamber rises back into the square box, the outer sealing plate is precisely embedded in the outer groove, achieving a seal at the connection between the collection chamber and the square through hole, effectively preventing external dust and other impurities from entering the box through the square through hole, thus avoiding contamination of coins or damage to electrical components.

[0020] Furthermore, rollers are symmetrically arranged at the top and bottom of one end of the fixed compartment door, and two sets of support plates that cooperate with the rollers are installed at the top and bottom of one end of the power supply box, and the height of the support plates is higher than that of the rollers.

[0021] With the above technical solution, since the height of the support plate is higher than that of the roller, when the fixed compartment door is closed, the roller rolls along the support plate, providing guidance and support for the closing of the fixed compartment door, ensuring that the fixed compartment door is accurately closed to the designated position, and improving the stability of the connection between the power supply box and the fixed compartment door, and significantly reducing the load on the hinge shaft connecting the power supply box and the fixed compartment door due to the weight of the power supply box itself and its internal components.

[0022] Furthermore, fixed brackets are symmetrically installed at the four corners of the outer side of the fixed compartment door, and fixed bolts are provided on the outer side of the fixed brackets.

[0023] Using the above technical solution, when installing the entire intelligent shared power metering box, the back of the intelligent shared power metering box is placed close to the wall or frame to be installed, and then the entire intelligent shared power metering box is fixedly installed using fixing bolts and fixing brackets.

[0024] The beneficial effects of the present invention are as follows: (1) The collection mechanism of the present invention uses a nested design of a square box and a collection box, and a combination of servo motor + gear transmission + double threaded rod for the drive mechanism. The collection box is automatically raised and lowered by the first lifting plate and the connecting block, so that the collection box automatically extends from the bottom of the power box. This allows the coins in the collection box to be taken out without opening the power box, and there is no need for manual handling of the collection box; (2) The discharge mechanism of the present invention uses a linkage design of connecting rod and guide plate. During the descent of the collection box, the two sets of guide plates can be automatically controlled to gradually tilt, so that when the discharge port is exposed at the bottom of the power box, the coins in the collection box can be poured out from the discharge port due to gravity, realizing the rapid and concentrated collection of coins. There is no need to disassemble the collection box, and the operation is intelligent. And it is efficient; (3) The self-locking mechanism and the drive mechanism of the present invention share the power source of the threaded rod. When the fixed compartment door is closed, the threaded rod drives the second lifting plate to rise, so that the L-shaped plug is accurately inserted into the fixed slot of the fixed compartment door, realizing the automatic self-locking of the compartment door. No additional lock is required, which simplifies the structure and improves the anti-theft performance, effectively preventing illegal opening of the box to steal coins or damage the internal components; (4) The heat dissipation mechanism of the present invention adopts the airflow circulation design of "intake fan + air guide plate + collection compartment + exhaust fan". The intake fan introduces external cold air, which is directed to the internal heat-generating components (control panel, power switch) through the air guide plate. The hot air is concentrated through the collection compartment and discharged by the exhaust fan, forming an efficient heat dissipation channel, avoiding the electronic components from malfunctioning due to excessive temperature inside the box.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] like Figures 1-9 and Figure 14As shown, the intelligent shared power metering box of this embodiment includes a power box body 1. A fixed compartment door 11 is hinged to one end of the back of the power box body 1. A display screen 2 is installed on the top of the front of the power box body 1. A control panel 9 and a power switch 10 are installed from top to bottom on the side of the power box body 1 away from the fixed compartment door 11. A coin acceptor 3 is installed on the top of the front of the power box body 1, and the coin outlet of the coin acceptor 3 is located inside the power box body 1. A coin collection mechanism 4 is provided at the bottom of the power box body 1 near the coin acceptor 3. A drive mechanism 5 that provides power to the collection mechanism 4 is provided inside the power box body 1 near the fixed compartment door 11. Fixed brackets 12 are symmetrically installed at the four corners of the outer side of the fixed compartment door 11. Fixing bolts are provided on the outside of the frame 12. The back of the power supply box 1 is placed close to the wall or frame to be installed. The entire metering box is securely installed using the fixing brackets 12 at the four corners of the fixed compartment door 11 and the matching fixing bolts. The collection mechanism 4 includes a square-shaped compartment 401, located at the bottom of the power supply box 1 near the coin acceptor 3. A square through-hole 403 communicating with the bottom of the square-shaped compartment 401 is provided at the bottom of the power supply box 1. A collection compartment 402 for collecting coins is provided inside the square-shaped compartment 401. Users insert coins through the coin acceptor 3 on the front of the power supply box 1. The coins fall directly into the collection compartment 402 through the outlet of the coin acceptor 3, achieving centralized coin collection. A row of... Outlet 404, the bottom of the inner side of the square through hole 403 is provided with an outer groove 16, and the diameter of the outer groove 16 is larger than the diameter of the square through hole 403. The bottom of the collection chamber 402 is equipped with an outer sealing plate 15 that matches the outer groove 16. The drive mechanism 5 includes a threaded rod 501, and two sets of threaded rods 501 are provided. The two sets of threaded rods 501 are located at one end inside the power supply box 1 near the fixed chamber door 11. The outer sides of the two sets of threaded rods 501 are threaded with a first lifting plate 502. The two ends of the square frame chamber 401 near the threaded rods 501 are symmetrically provided with strip-shaped through holes 504. The two ends of the first lifting plate 502 near the square frame chamber 401 are symmetrically provided with connecting blocks 505, and the connecting blocks 505 are located away from the first lifting plate 502. A power assembly 503 is provided on one side of the rectangular container 401, passing through the strip-shaped through hole 504 and fixedly connected to the outside of the collection bin 402. This power assembly 503 drives two sets of threaded rods 501 to rotate. The power assembly 503 includes a servo motor 5031 located at the bottom center of one side of the rectangular container 401. A drive gear 5032 is mounted on the output shaft of the servo motor 5031. Driven gears 5033, which mesh with the drive gear 5032, are symmetrically mounted on the bottom outer sides of the two sets of threaded rods 501. When coins need to be collected, the output shaft of the servo motor 5031 is controlled to drive the drive gear 5032 to rotate via an external controller and the communication module of the control panel 9. The drive gear 5032 meshes with the driven gears 5033 at the bottom of the two sets of threaded rods 501 for transmission.The two sets of threaded rods 501 rotate synchronously in the same direction. Since the first lifting plate 502 is threadedly engaged with the two sets of threaded rods 501, the rotation of the threaded rods 501 forces the first lifting plate 502 to rise and fall axially along the threaded rods 501 via threaded transmission. The first lifting plate 502, through connecting blocks 505 at both ends, drives the collection chamber 402 to rise and fall synchronously. After the discharge port 404 is fully exposed, the operator can remove the coins collected in the collection chamber 402 through the discharge port 404. The strip-shaped through hole 504 provides guidance and clearance space for the movement of the connecting block 505. After the coins are collected, the servo motor 5031 is controlled to rotate in the opposite direction, causing the collection chamber 402 to rise back into the square-shaped chamber 401. At this time, the outer sealing plate 15 at the bottom of the collection chamber 402 is precisely embedded in the outer groove 16 at the bottom of the inner side of the square through hole 403, achieving a seal at the connection.

[0042] like Figure 4 and Figures 8-10 As shown in this embodiment, the collecting mechanism 4 is internally equipped with a discharging mechanism 6 for emptying coins. The discharging mechanism 6 includes a first guide plate 601 located at the bottom of the collecting chamber 402. A strip-shaped channel 603 is symmetrically formed at the bottom of the collecting chamber 402 on both ends away from the discharge port 404. A first rotating shaft 602, cooperating with the strip-shaped channel 603, is symmetrically installed on both ends of the first guide plate 601 on the ends away from the discharge port 404. A second guide plate 604 is inserted into the side of the first rotating shaft 602 near the discharge port 404, and both ends of the second guide plate 604 are hinged to the inner ends of the discharge port 404 via a second rotating shaft 605. Two sets of connecting rods 606 are hinged to the top of the first guide plate 601 on the side away from the discharge port 404. The top ends of both sets of connecting rods 606 are fixedly connected to the top of the outer side of the square-shaped chamber 401. Coins inserted into the coin acceptor 3... After falling into the collection chamber 402, the coins accumulate on the bearing surface formed by the first guide plate 601 and the second guide plate 604. When the collection chamber 402 moves downward, the first guide plate 601, which is hinged to the two sets of connecting rods 606, is gradually stretched as the collection chamber 402 descends. This causes the first guide plate 601 and the second guide plate 604 to rotate synchronously around the second rotating shaft 605. During rotation, the first rotating shafts 602 at both ends of the first guide plate 601 move upward within the strip groove 603 of the collection chamber 402, while simultaneously driving the second guide plate 604 to gradually extend out from the first guide plate 601. When the collection chamber 402 descends until the outlet 404 is completely exposed from the bottom of the power supply box 1, the first guide plate 601 and the second guide plate 604 together form an inclined guide channel. Under the action of gravity, the coins in the collection chamber 402 pour out from the outlet 404 along the guide channel, completing the automatic emptying of the coins.

[0043] like Figures 2-4 and Figure 11As shown, the inner side of the fixed compartment door 11 in this embodiment is provided with a self-locking mechanism 7 that cooperates with the drive mechanism 5. The self-locking mechanism 7 includes two sets of fixed slots 703 located inside the fixed compartment door 11. The top ends of the outer sides of the two sets of threaded rods 501 are threaded with a second lifting plate 701. At the middle position of the top of the second lifting plate 701 and the first lifting plate 502, an L-shaped plug 702 adapted to the fixed slot 703 is installed. The inlet end of the fixed slot 703 faces downward. After the fixed compartment door 11 is closed, the servo motor 5031 is controlled by the control panel 9 to drive the two sets of threaded rods 501 to rotate, which drives the first lifting plate 502 and the second lifting plate 701 to rise synchronously. When the first lifting plate 502 and the second lifting plate 701 rise to the designated position, the L-shaped plug 702 at the top of the first lifting plate 502 and the second lifting plate 701 is precisely inserted into the fixed slot 703 inside the fixed compartment door 11. The self-locking and fixing of the fixed compartment door 11 is achieved by using the limiting effect of the L-shaped structure.

[0044] like Figures 1-4 and Figures 12-13 As shown, the power supply housing 1 of this embodiment is equipped with a heat dissipation mechanism 8 for heat dissipation. The heat dissipation mechanism 8 includes an intake fan 801, which is located at the bottom of the power supply housing 1 near the power switch 10. A guide component 802 is provided at the bottom of the power supply housing 1 near the intake fan 801. A collection chamber 804 is symmetrically installed at the top of both ends of the power supply housing 1, and an air outlet 805 is provided at the top of the collection chamber 804. An exhaust fan 803 communicating with the inside of the collection chamber 804 is symmetrically installed at the top of both ends of the power supply housing 1. The guide component 802 includes a guide component located at the bottom of the power supply housing 1 near the intake fan 801. The mounting bracket 8021 above the fan 801 has several sets of air guide plates 8022 evenly installed on its inner side. When the metering box is working, the control panel 9 controls the intake fan 801 and the exhaust fan 803 to start. The intake fan 801 introduces cold air from the outside. The cold air flows through several sets of air guide plates 8022 and is guided in a directional manner, precisely flowing to the control panel 9, the power switch 10 and other core heat-generating components. The hot air that has absorbed heat rises to the top of the box and then enters the collection chamber 804 through the air outlet 805 for centralized collection. Finally, it is discharged through the exhaust fans 803 at both ends of the power supply box 1.

[0045] like Figure 4 and Figure 11As shown, in this embodiment, rollers 13 are symmetrically arranged at the top and bottom of the inner side of the fixed compartment door 11. Two sets of support plates 14 that cooperate with the rollers 13 are installed at the top and bottom of the inner side of the power supply box 1. The height of the support plate 14 is higher than that of the rollers 13. When the fixed compartment door 11 is closed, the rollers 13 at the top and bottom of the inner side of the fixed compartment door 11 contact the support plates 14 at the corresponding positions inside the power supply box 1. As the compartment door closes, the rollers 13 roll along the surface of the support plate 14, providing guidance for the closing of the fixed compartment door 11. At the same time, the height of the support plate 14 is higher than that of the rollers 13, which can support the power supply box 1 and share the pressure of the power supply box 1 and the internal components of the power supply box 1 on the hinge shaft.

[0046] The working principle of this embodiment is as follows: the user inserts coins through the coin acceptor 3 on the front of the box. The coins fall into the collection bin 402 through the coin acceptor outlet. While the entire shared power metering box is charging the equipment, the intake fan 801 is controlled to introduce external cold air. The cold air is directionally guided by the air guide plate 8022 and flows precisely to the core heat-generating components such as the control panel 9 and the power switch 10. The hot air, after absorbing heat, rises to the top of the box and enters the collection bin 804 for centralized collection. Finally, it is discharged from the box through the exhaust fans 803 at both ends of the box and through the air outlet 805, forming a highly efficient "intake-directional heat dissipation-hot air collection-exhaust" process. Airflow circulation; when coins need to be collected, the external controller, in conjunction with the communication module on the control panel 9, controls the servo motor 5031 to drive the drive gear 5032 to rotate. The drive gear 5032 meshes with the driven gears 5033 at the bottom of the two sets of threaded rods 501, driving the two sets of threaded rods 501 to rotate synchronously. The thread action forces the first lifting plate 502 to descend. The first lifting plate 502, through the connecting block 505, drives the collection bin 402 to move downward along the axial direction of the threaded rods 501. During the descent of the collection bin 402, the connecting rod 606 hinged at its top is connected to the collection bin and the square frame at its two ends respectively. The collection chamber 401 is fixedly connected. As the collection chamber 402 descends, it gradually stretches, causing the first guide plate 601 and the second guide plate 604 to rotate together around the second rotating shaft 605. During this process, the first rotating shaft 602 moves upward inside the strip-shaped through groove 603, and the second guide plate 604 gradually extends out from the first guide plate 601. When the collection chamber 402 extends from the bottom of the power supply box 1 (only the discharge port 404 needs to be fully exposed), the square-shaped chamber 401 no longer blocks the discharge port 404. Under the action of gravity, the coins inside the collection chamber 402 automatically flow out from the discharge port 404, guided by the first guide plate 601 and the second guide plate 604. After the coins are collected, the servo motor 5031 is controlled to rotate in the opposite direction, causing the first lifting plate 502 to move upward and the collection chamber 402 to rise back into the square chamber 401. The outer sealing plate 15 is re-embedded into the outer groove 16 to achieve a seal. When the chamber door needs to be opened, the servo motor 5031 is controlled to rotate via the control panel 9 (provided that the outlet 404 is fully exposed). The threaded rod 501 drives the second lifting plate 701 to move downward (the first lifting plate 502 also descends synchronously). The L-shaped insert 702 completely disengages from the fixed slot 703, the self-locking is released, and the fixed chamber door 11 can be easily opened.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
