Description

Foldable solar powered outdoor water sign machine Technical Field

[0001] The present application relates to the technical field of water sign machine devices, and specifically to a foldable solar-powered outdoor water sign machine. Background Art

[0002] Water sign machines serve as notice boards to display content. With the development of the electronic age, water signs have evolved from the old Chinese folk lacquered wooden signs and thin iron signs used for leaving messages and taking notes to new water sign machines with electronic display screens as carriers.

[0003] Electronic water sign machines can also be used by users as advertising machines. Depending on the setting scenario, they are divided into two categories: fixed and mobile. Mobile electronic water sign machines have some practical advantages over fixed water sign machines. For example, users with mobile operations can carry and place them as needed. Depending on the rainfall, the water sign machine placed at the store entrance can be moved to avoid rain. When doing outdoor promotion activities, it can switch the display pictures and videos more flexibly than fixed content display boards. However, mobile outdoor water sign machines also have some obvious disadvantages. For example, in outdoor advertising scenarios, they often cannot be connected to a suitable power source for power supply, or they need to use long wires to obtain power. Even if some outdoor water sign machines have built-in batteries, the battery capacity is very limited due to the portability of outdoor water sign machines.

[0004] At present, the patent application document with patent application number CN202020000311.9 discloses a movable foldable solar panel, which is provided with a first solar panel assembly and a second solar panel assembly that can be flipped along the height direction of the advertising screen as an axis through a connecting piece. Although this advertising machine with a solar power generation panel that can be self-powered makes up for the insufficient capacity of the above-mentioned built-in battery, the provision of two solar panels undoubtedly increases the thickness and overall weight of the advertising machine, losing the advantage of portability; and when the solar panels are unfolded relative to the advertising machine, the solar panels located on both sides of the advertising screen are not beautiful enough, which is contrary to the current popular full-screen narrow-frame aesthetic trend. After the solar panels are unfolded, the windward area increases, and the thin plate structure is easily blown over and over by the wind, which is dangerous and can hit bystanders; because the energetic sunlight shines on the surface of the object, different angles of reception receive different amounts of energy, and this solar advertising machine also does not have a solar panel elevation adjustment function, and cannot be adjusted to a more suitable elevation angle to more efficiently convert solar energy into electrical energy.

[0030] 1 to 8 , this embodiment provides a foldable solar-powered outdoor water sign machine, including:

[0031] Display screen 1;

[0032] a solar panel 2, wherein the upper edge of the solar panel 2 is rotatably connected to the upper edge of the display screen 1;

[0033] The adjusting fixing member 3 is connected to the display screen 1 and the solar panel 2. When the solar panel 2 is rotated to a predetermined angle relative to the display screen 1, the adjusting fixing member 3 is used to keep the solar panel 2 fixed to the display screen 1.

[0034] With this structure, solar panel 2 is located on the back side of display screen 1. When display screen 1 is facing the audience, the audience does not see solar panel 2, which would otherwise affect their visual experience. This improves the aesthetics compared to existing technologies. When solar panel 2 rotates relative to display screen 1, the bottom of solar panel 2 moves away from the bottom of display screen 1, opening in an inverted "V" shape. Alternatively, the bottom of solar panel 2 can be moved closer to the bottom of display screen 1, allowing the display screen 1 and solar panel 2 to rest against each other for easy storage. Solar panel 2 provides power for display screen 1 to play videos, images, and audio. When the solar panel 2 is facing an angle that does not allow sufficient sunlight to reach the display screen, the upper edge of solar panel 2, pivoting to the upper edge of display screen 1, allows solar panel 2 to rotate, adjusting its elevation angle to maximize the amount of sunlight received and improve energy reception. Once the angle is adjusted, the adjustment fixture 3 secures the solar panel 2 to the display screen 1, preventing relative rotation between them.

[0035] Furthermore, compared with the existing technology that cannot adjust the elevation angle of the solar panel and can only rely on increasing the number of solar panels to increase the energy receiving area, this water sign machine saves the number of solar panels, reduces production costs, and is lighter and more portable.

[0036] 2 and 4 , the display screen 1 and / or the solar panel 2 are provided with a receiving groove 150 . When the display screen 1 and the solar panel 2 are overlapped, the adjusting and fixing member 3 is received in the receiving groove 150 .

[0037] When the adjusting fixture 3 is disposed between the display screen 1 and the solar panel 2 , in order to prevent the adjusting fixture 3 from affecting the overlap of the display screen 1 and the solar panel 2 .

[0038] 3 to 5 and 8 , the adjusting fixing member 3 is any one of a nitrogen spring and a limiter, and both ends of the adjusting fixing member are rotatably connected to the display screen 1 and the solar panel 2 respectively.

[0039] In a preferred embodiment, the number of the storage slots 150 is two groups. The display screen 1 is provided with a storage slot 150, and the solar panel 2 is also provided with a storage slot 150. Both ends of the main body of the nitrogen spring have a rotating connection seat 310 installed in the storage slot 150; when the display screen 1 and the solar panel 2 are overlapped, the nitrogen spring is completely stored in the storage slot 150; in order to improve stability, the number of nitrogen springs can be set to two groups.

[0040] When the section fixing part 3 is a limiter, the limiter has a positioning pin and multiple limiting groove structures. The positioning pin enters into different limiting grooves to cooperate, which can keep the display screen 1 and the solar panel 2 at the corresponding expansion angle after they rotate.

[0041] Please refer to Figures 1 and 4. The display screen 1 includes a protective front panel 110, a display panel 120, a first middle frame 130, a first rear cover 140, a first battery 4, a speaker 5, and a main control board 6; the protective front panel 110 and the first rear cover 140 are connected to the first middle frame 130, enclosing the display panel 120, the first battery 4, the speaker 5, and the main control board 6 between the protective front panel 110 and the first rear cover 140, and the protective front panel 110 is provided with a display area 111 corresponding to the display panel 120; the main control board 6 is electrically connected to the display panel 120, the first battery 4, and the speaker 5.

[0042] In some embodiments, the first battery 4 , the speaker 5 , and the main control board 6 are connected to the first middle frame 130 through the pressing plate 14 and the horizontal strip plate 15 and fixed to the first middle frame 130 .

[0043] The main control board 6 controls the display panel 120 to display images and video content, and the speaker 5 to play audio. The first battery 4 receives power from the solar panel 2 and then provides power to various components. The protective front panel 110, the first middle frame 130, and the first rear cover 140 enclose these components, providing support and structural protection, as well as waterproof and dustproof properties.

[0044] The sound hole 141 corresponding to the speaker 5 is set on the first rear cover 140, which can provide waterproof protection for the speaker 5.

[0045] 1 and 4 , the solar panel 2 includes a second rear cover 210, a second middle frame 220, a second battery 7, a solar power generation panel 230, and a solar panel controller 8. The second rear cover 210 and the solar power generation panel 230 are connected to the second middle frame 220, enclosing the second battery 7 and the solar panel controller 8 between the second rear cover 210 and the solar power generation panel 230. The solar panel controller 8 is electrically connected to the second battery 7, the solar power generation panel 230, and the first battery 4.

[0046] The solar panel controller 8 can regulate the operation of the solar panel 230 and transmit the circuit to the second battery 7 and the first battery 4. This part can be implemented using existing technology and will not be described in detail here.

[0047] The second rear cover 210, the second middle frame 220, and the solar panel 230 enclose the solar panel controller 8 and the second battery 7, providing support structure protection and waterproof and dustproof properties; the second battery 7 and the solar panel controller 8 can be installed and fixed on the second middle frame 220 through the horizontal strip 15.

[0048] 2 and 4 , a flat support leg 131 is provided at the lower edge of the first middle frame 130 ; a rotating wheel 9 is provided at the lower edge of the second middle frame 220 .

[0049] When the display screen 1 and the solar panel 2 are overlapped, the entire water card machine can be moved by sharing the rotating wheel 9, and when the display screen 1 and the solar panel 2 are unfolded, they can also be stopped on the current ground using the flat support legs 131 without the need for additional fixing auxiliary devices.

[0050] In some embodiments, the rotating wheel 9 can be a universal wheel.

[0051] Please refer to Figure 4, including a cable connector 10, two of which are respectively embedded on the first rear cover plate 140 and the second rear cover plate 210; the first rear cover plate 140 and / or the second rear cover plate 210 are provided with a receiving groove 160 corresponding to the cable connector 10.

[0052] Receiving groove 160 accommodates both the cable connector 10 and the cables that electrically connect the display screen 1 and the solar panel 2 when the two are stacked. This thoughtful design prevents the presence of cables from causing a loose fit between the display screen 1 and the solar panel 2. The cable connector 10 secures and secures incoming and outgoing wires, providing protection from water, dust, and vibration, keeping the interiors of the display screen 1 and solar panel 2 clean and safe.

[0053] 2 and 4 , a waterproof antenna 11 and a waterproof switch 12 are provided on the upper edge of the first middle frame 130 ; the waterproof antenna 11 and the waterproof switch 12 are electrically connected to the main control board 6 .

[0054] The waterproof antenna 11 and the waterproof switch 12 are preferably arranged below the edge protection 132. This can protect the waterproof antenna 11 and the waterproof switch 12.

[0055] Please refer to Figure 2. The display screen 1 and the solar panel 2 are hinged by a hinge 13; the display panel 120 is a liquid crystal display screen; the adjustment fixing member 3 is any one of a self-locking nitrogen spring and an arbitrary stop nitrogen spring; the protective front panel 110 is hard glass.

[0056] The display panel 120 can be any one of an LCD screen, an LED screen, an OLED screen, and a miniLED screen. When the display panel 120 uses a miniLED screen, the overall thickness and weight of the display screen 1 can be further reduced, thereby enhancing portability.

[0057] When the adjustment fixture 3 is a self-locking nitrogen spring, it has a built-in locking protection sleeve, ensuring that the supporting force does not fail and preventing unexpected safety measures, which is safer and more reliable. When the adjustment fixture 3 is an arbitrary stop nitrogen spring, it can be stopped at any position without the need for additional locking force. Once the user adjusts the solar panel 2 to the predetermined elevation angle relative to the display 1, the nitrogen spring will automatically maintain the solar panel 2 in place at that angle without any additional operation.

[0058] Referring to Figures 6 and 7 , in some embodiments, the adjustable fixing member 3 can be a curved connecting plate 16 having an arcuate elongated slot 1610, with one end of the connecting plate 16 being pivotally connected to the side of the display screen 1 or the solar panel 2. For example, in the case of pivotally connecting one end of the connecting plate 16 to the display screen 1, a screw is passed through the arcuate elongated slot 1610. Once the solar panel 2 is rotated and deployed relative to the display screen 1 to a certain angle, the screw is tightened into a threaded hole on the side of the solar panel 2 to securely connect the connecting plate 16 to the solar panel 2. Alternatively, a bolt extending outwardly from the side of the solar panel 2 can be passed through the arcuate elongated slot 1610 and connected to the bolt using a butterfly nut to securely connect the connecting plate 16 to the side of the solar panel 2. In some embodiments, the curved connecting plate 16 has a two-section structure that can be rotated and folded.

[0059] In some embodiments, the protective front panel 110 may be made of tempered glass to improve durability. The display area 111 on the protective front panel 110 , corresponding to the display area of ​​the display screen 1 , is light-transmissive.

[0060] 1 , the front projection outline area of ​​the display screen 1 is substantially equal to the front projection outline area of ​​the solar panel 2 ; a side guard 132 is provided on the upper edge of the first middle frame 130 , and the side guard 132 is symmetrically arranged with the planar support foot 131 .

[0061] With this design, the display screen 1 and the solar panel 2 are superimposed and pressed against each other. When viewed from the front, the two have a visually overlapping effect, which is aesthetically pleasing and convenient for storage.

[0062] The edge guard 132 is symmetrically arranged with the flat support 131, which has a symmetrical and beautiful appearance. The flat support 131 can also raise the display panel 120 higher than the ground to prevent water from entering the display screen 1.
