Description

Technical Field

[0001] This invention belongs to the field of power marketing service equipment, and specifically relates to a smart power marketing service terminal. Background Technology

[0002] With the deepening of the digital transformation of the power grid, user-centric service models have become a key focus of the power industry. As a core terminal device connecting the power grid and users, the intelligent power marketing service terminal is widely deployed in various scenarios such as business halls, community outlets, office buildings, and remote transformer areas. It undertakes diversified service functions such as electricity bill inquiry and payment, business processing, electricity card writing, electricity information collection, and load monitoring. It effectively makes up for the shortcomings of slow response and limited coverage of traditional offline service models, and greatly improves the convenience and efficiency of power services. It is one of the important supporting equipment for building an intelligent power service system.

[0003] Currently, most smart service terminals for power marketing on the market are equipped with touch screens as the core component for human-computer interaction. These touch screens are installed in a window on the device, allowing for convenient handling of various services through touch operation. The terminals typically have window covers to protect internal interfaces, consumable storage compartments, maintenance components, and functional modules, balancing equipment safety and ease of maintenance. However, existing smart service terminals for power marketing still have significant shortcomings in their structural design.

[0004] Regarding touchscreen angle adjustment, existing smart power marketing service terminals mostly use fixed installation methods, making it impossible to adapt the angle to user needs. They often only have simple manual adjustment mechanisms, resulting in cumbersome adjustments and poor positioning stability. Since the users of smart power marketing service terminals include users of different heights and with different operating habits, fixed-angle touchscreens force users to bend over, lean forward, or look up to adjust, leading to fatigue during prolonged use, especially for elderly users and those who are shorter or taller, significantly reducing ease of operation and even causing touch misoperations. Furthermore, in different lighting conditions, fixed-angle touchscreens are prone to glare, obscuring displayed content and further affecting the interactive experience and operational accuracy. Some similar terminals with angle adjustment functions have complex adjustment structures, high manufacturing costs, and are prone to malfunctions such as adjustment jamming and loosening, making them unsuitable for the diverse deployment needs of power terminals.

[0005] In addition, regarding the opening and closing of the window cover, the window cover of the existing power marketing intelligent service terminal mostly adopts traditional structural designs such as bolt fastening, simple buckle snap-fit, or hinge connection, which have problems such as inconvenient opening and closing and difficulty in balancing fastening and protection. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention aims to provide an intelligent power marketing service terminal. This device can provide a wide range of power business services, and the touch screen on the device has a very convenient angle, allowing for flexible opening and closing of the window cover. It can balance user operation convenience with equipment protection and stability, meeting the development needs of intelligent and refined services in the power service industry.

It ensures business and data security and compliance through full-link encryption, dual identity verification and permission control. It can achieve stable deployment in multiple scenarios, take into account the needs of special users, and ultimately create an efficient, safe, inclusive and highly adaptable intelligent self-service system for power marketing.

[0017] 2. When adjusting the angle of the touch screen, the operator first pushes the push plate with one hand, using the two inclined surfaces of the wedge plate to press the rotating blocks of the angle adjusters on both sides, causing the rotating blocks to move inward towards the cylinder seat. This pushes the locking block away from the sleeve and compresses the spring through the shaft, disengaging the first and second engagement teeth. At this point, the operator can rotate and adjust the angle of the touch screen with the other hand. This, in turn, drives the rotating block, shaft, and locking block to rotate within the cylinder seat via the adjusting rod. After the touch screen is adjusted to the correct position, the push plate is released. Under the action of the spring force, the locking block, shaft, rotating block, and wedge plate reset. The engagement of the first and second engagement teeth causes the locking block to re-engage and lock with the sleeve, thereby fixing the shaft, rotating block, and adjusting rod. This achieves locking after the touch screen angle is adjusted, adapting to adjustment in different usage environments.

[0018] 3. In non-business operations, this application requires the window to be sealed and protected. This can be achieved by controlling a motor to drive a screw to rotate, and under the sliding limit of the slide rod, causing the sealing plate to move vertically through the strip hole upwards, thereby effectively sealing the window and completing the safety protection of structures such as touch screens inside the window.

[0028] The intelligent power marketing service terminal of this invention achieves a one-stop, end-to-end self-service closed loop by linking touch screen 2 with modules such as voice interaction, identity recognition, core power business processing, payment settlement, invoice printing, IoT linkage, and security protection. It realizes real-name verification, business processing, fee payment, and voucher output. Relying on multimodal interaction and two-way data communication with the Internet of Things, it improves service efficiency and remote management capabilities. Through full-link encryption, dual identity verification, and access control, it ensures business and data security and compliance, achieves stable deployment in multiple scenarios, and takes into account the needs of special users. Ultimately, it creates an efficient, safe, inclusive, and highly adaptable intelligent self-service system for power marketing.

[0029] Specifically, the angle adjustment assembly includes a wedge plate 5 and two horizontally symmetrically arranged angle adjusters 4. Each adjuster includes a cylinder base 41, a spring 43, and a circular rotating block 42. The cylinder base 41 is fixed to the bottom plate 13 by a fixing plate. The rotating block 42 is coaxially movably disposed at a circular side opening 410 on the side of the cylinder base 41. The lower end of the adjusting rod 3 is fixedly connected to the circumference of the rotating block 42 perpendicular to the axis of the rotating block 42, and the upper end of the adjusting rod 3 is fixedly connected to the bottom of the touch screen 2. A circular locking block 44 is coaxially movably disposed in the cavity inside the cylinder base 41. A sleeve 45 is coaxially fixed inside the sleeve 45. A first engagement tooth 451 is provided on the circumference of the side end face of the sleeve 45 near the locking block 44. A second engagement tooth 441 that cooperates with the first engagement tooth 451 is provided on the side face of the locking block 44 near the sleeve 45. One end of the spring 43 abuts against the inner wall of the sleeve seat 41, and the other end abuts against the side of the locking block 44 away from the second engagement tooth 441. One end of the shaft 46 is coaxially and horizontally fixed in the middle of the locking block 44. The other end of the shaft 46 passes through the sleeve 45 and is coaxially fixed to the rotating block 42 (the diameter of the rotating block 42 is smaller than the inner diameter of the sleeve 45).

[0030] The wedge plate 5 is horizontally positioned below the base plate 13 between the two angle adjusters 4, and slides along a line perpendicular to the line connecting the two angle adjusters 4. Specifically, a slide rail is mounted on the bottom surface of the base plate 13, and the wedge plate 5 is slidably mounted on the slide rail. The two inclined surfaces of the wedge plate 5 abut against the rotating blocks 42 of the two angle adjusters 4, respectively; a push plate 51 is fixed on the wedge plate 5, and the push plate 51 extends upward through the second through hole 132 on the base plate 13.

[0031] When the angle of the touch screen 2 needs to be adjusted, the operator first pushes the push plate 51 with one hand, using the two inclined surfaces of the wedge plate 5 to press the rotating blocks 42 of the angle adjusters 4 on both sides, causing the rotating blocks 42 to move inward toward the cylinder seat 41. This pushes the locking block 44 away from the sleeve 45 and compresses the spring 43 through the shaft 46, causing the first engagement tooth 451 to disengage from the second engagement tooth 441. At this time, the operator can rotate and adjust the angle of the touch screen 2 with the other hand, and then drive the rotating block 42 and the shaft through the adjusting rod 3. The rod 46 and the locking block 44 rotate within the cylinder seat 41. After the touch screen 2 is adjusted to the correct position, the push plate 51 is released. Under the elastic force of the spring 43, the locking block 44, the shaft 46, the rotating block 42, and the wedge plate 5 are reset. The locking block 44 is re-engaged and locked with the sleeve 45 through the meshing of the first engagement tooth 451 and the second engagement tooth 441. This fixes the shaft 46, the rotating block 42, and the adjusting rod 3, thus achieving locking after the angle adjustment of the touch screen 2 and adapting to adjustment in different usage environments.

[0032] The lifting drive assembly includes a slide rod 61, a screw rod 62, and a motor 64. The slide rod 61 and screw rod 62 are vertically installed inside the body 1 below the base plate 13. A sealing plate 63 is vertically disposed between the slide rod 61 and the screw rod 62. One side of the lower end of the sealing plate 63 is slidably sleeved on the slide rod 61, and the other side is threaded onto the screw rod 62. The end of the screw rod 62 is poweredly connected to the motor 64. Specifically, a first bevel gear 621 is coaxially fixed to the end of the screw rod 62, and a second bevel gear 641 is coaxially fixed to the horizontally positioned output shaft of the motor 64. The two bevel gears mesh vertically.

[0033] In non-business operations, this application requires sealing and protecting window 11. This can be achieved by controlling motor 64 to drive screw 62 to rotate, and under the sliding limit of slide rod 61, causing sealing plate 63 to move vertically through strip hole 133 upward, thereby effectively sealing window 11 and completing the safety protection of structures such as touch screen 2 inside window 11.

[0034] In addition, a cover plate 14 is provided on the top surface of the base plate 13 at the opening of the strip hole 133. The long side of the cover plate 14 is rotatably connected to the edge of the opening of the strip hole 133 by a hinge of spring 43. The area of ​​the cover plate 14 is larger than the opening area of ​​the strip hole 133.

[0035] Under the elastic force of the spring 43 hinge, the cover plate 14 will seal the strip hole 133, thereby effectively preventing foreign objects from entering the body 1; when the sealing plate 63 rises upward through the strip hole 133, it will push the cover plate 14 to one side without affecting the vertical movement of the sealing plate 63; when the sealing plate 63 falls back to below the bottom plate 13, under the elastic force of the spring 43 hinge, the cover plate 14 will reseal the strip hole 133.

[0036] When adjusting the angle of the touch screen 2 using the present invention, the wedge plate 5 is moved by the push plate 51, which in turn drives the angle adjusters 4 on both sides to move, thereby effectively adjusting the vertical angle of the touch screen 2. In non-business state, the screw 62 can be rotated by controlling the motor 64, so that the sealing plate 63 pushes the cover plate 14 vertically upward, thereby effectively sealing the window 11, thus completing the safety protection of the touch screen 2 and other structures inside the window 11.
