[0002] In daily life, when conducting educational publicity and display, a fixed display method of a single page is usually adopted. This method has the disadvantages of small publicity and display pages, little publicity content, and single content. The internal publicity content of existing publicity and display devices is usually fixed and cannot achieve good publicity effects over a large range. In actual use, it is less attractive to people, not easy to attract readers' attention, and the publicity efficiency is low. In addition, some publicity and display devices require an external fixed power supply to be used normally when used outdoors, which is inconvenient to use without an external power supply. Utility Model Content

[0003] The purpose of the utility model is to provide a multifunctional and recyclable educational publicity display device based on photoelectric conversion, so as to solve the problems of the fixed display method of a single page in the prior art, such as small publicity display pages, few publicity contents and single contents, and the problem that some publicity protection devices requiring an external power supply are inconvenient to use when there is no external power supply when used outdoors.

[0004] The utility model is realized by the following technical solutions:

[0005] A multifunctional and recyclable educational publicity and display device based on photoelectric conversion comprises: a display component, a solar photovoltaic power generation device and a transmission component, wherein the solar photovoltaic power generation device is fixedly connected to the upper part of the display component, and the solar photovoltaic power generation device is connected to the transmission component through a wire and supplies power; the display component comprises a display frame and a display curtain built into the display frame, and the transmission component comprises a motor, an active transmission component driven by the motor, and a driven transmission component connected to the active transmission component through the display curtain, and the display curtain is wound around the active transmission component and the driven transmission component.

[0006] The fixed display method using a single page has the problem that the promotional display page is small, the promotional content is small and the content is single, and some promotional protection devices that require an external power supply are inconvenient to use when there is no external power supply when used outdoors. The utility model provides a multifunctional and recyclable educational promotional display device based on photoelectric conversion. The device drives the transmission shaft to rotate by a motor powered by a photovoltaic power generation device, and at the same time drives the curtain connected to the transmission shaft by friction, so as to realize the replacement of the promotional content. Compared with the fixed display method of single-page display, the device solves the problem of single promotional content. At the same time, the use of photovoltaic power generation to drive the motor makes the promotional display independent of a fixed power supply, thereby facilitating outdoor use.

[0007] Furthermore, the active transmission component includes a first transmission shaft connected to the output end of the motor; the display curtains are connected end to end, and the display curtain bypasses the first transmission shaft and is connected to the driven transmission component.

[0008] By connecting the display curtains end to end, the display curtains can be displayed in a circular manner as the transmission components rotate.

[0009] Further, the driven transmission member includes a second transmission shaft, a third transmission shaft, a fourth transmission shaft and a fifth transmission shaft, all of which are parallel to the first transmission shaft;

[0010] The third transmission shaft is located above the first transmission shaft, the fifth transmission shaft is located above the second transmission shaft, and the fourth transmission shaft is lower than the third transmission shaft and the fifth transmission shaft and higher than the second transmission shaft and the first transmission shaft;

[0011] The display curtain passes around the first transmission shaft, the fourth transmission shaft, the second transmission shaft, the fifth transmission shaft and the third transmission shaft in sequence.

[0012] Conventional promotional display devices with page-turning functions can usually only replace two promotional pages. By setting the transmission component into two parts, upper and lower parts, and including several parallel transmission shafts, the three upper transmission shafts form an inverted triangle structure, the size of the display curtain wound around the transmission shafts is increased, thereby increasing the amount of content of the promotional display.

[0013] Furthermore, the multifunctional and recyclable educational promotional display device based on photoelectric conversion also includes a supporting movable component, which includes a universal roller, a supporting column and a connecting plate that are fixedly connected in sequence, and the supporting movable component is fixedly connected to the display component via the connecting plate, and the supporting column is an inverted Y-shaped structure.

[0014] Promotional display devices are usually flat and need to be frequently repositioned. By adding supporting moving parts and using universal rollers, the promotional display devices can be easily moved in all directions. At the same time, the support columns with inverted Y-shaped structures have a larger bottom area than conventional rectangular or circular columns, which disperses the load and provides better support.

[0015] Furthermore, the number of the supporting moving parts is two and they are arranged symmetrically on the left and right.

[0016] The stability of the publicity display device is further improved by two supporting movable parts that are symmetrically arranged on the left and right.

[0017] Furthermore, the display component also includes a glass display plate fixedly connected to the inner wall of the display frame, and the top and bottom of the display component are respectively fixedly connected with an electronic display screen and a storage box.

[0018] By adding an electronic display screen, while the screen displays promotional content, it serves as a further auxiliary promotional method to enhance the functionality of the device. At the same time, the electronic display screen usually only requires simple electronic data transmission or document editing to change the promotional content, making it more convenient to change the promotional content of the device. In the process of a promotional display, there are situations where multiple screens are used. By adding a storage box to store the screens, it is convenient to store and retrieve the screens while also reducing the chance of screen loss.

[0019] Furthermore, the multifunctional and recyclable educational promotional display device based on photoelectric conversion also includes a telescopic plate, which includes a first support member fixedly connected to the top of the display component, a first telescopic part and a second telescopic part, the first telescopic part is slidably connected to the first support member, and the second telescopic part includes a sliding end and a shielding end slidably connected to the first telescopic part, and the shielding end is a downward curved arc structure.

[0020] When promotional display devices are used outdoors, they are usually exposed to the sun or rain. By adding a telescopic part on the top of the promotional display device as a shielding component, the promotional panel of the promotional display device is protected from the sun and rain, thereby increasing the service life of the device. The end of the shielding component is designed as a downward curved structure to help drain rain.

[0021] Furthermore, the multifunctional and recyclable educational promotional display device based on photoelectric conversion also includes a fixed bracket and a second support member fixedly connected to the display component, the second support includes a first connection end and a second connection end, the fixed bracket and the first connection end are both rotatably connected to the solar photovoltaic power generation device, and the fixed bracket is provided with a number of evenly distributed fixing grooves and the fixing grooves match the second connection end.

[0022] The core device of solar photovoltaic power generation device is solar photovoltaic panel, which generates electricity by receiving sunlight. When the photovoltaic panel is fixed, the effective area receiving sunlight varies due to the movement of the sun. By designing the mounting bracket with adjustable angle, the position of the solar photovoltaic panel can be adjusted according to the sun's altitude angle to achieve efficient reception of light energy.

[0023] Furthermore, the transmission component also includes a timer and a relay, the timer, the relay and the motor are connected in sequence, and the timer controls the action of the motor through the relay.

[0024] By using timers and relays to control the movement of motors, automatic timed changes of promotional curtains can be achieved, reducing manual operations while improving the degree of automation of the promotional display device.

[0025] Furthermore, a transverse rotating gear is provided at the output end of the motor, and a longitudinal rotating gear is provided on the active transmission component, and the transverse rotating gear is meshed with the longitudinal rotating gear.

[0026] Transmission is achieved by meshing the horizontal transmission gear with the longitudinal transmission gear, reducing the size of the transmission component in the horizontal direction, facilitating the placement of the motor at the frame of the display frame to avoid the motor being exposed, and increasing the service life of the transmission component.
