Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a foldable and portable outdoor video display device. Background Technology

[0002] With the increasing popularity of outdoor recreational activities, the drawbacks of traditional video display devices and existing portable projection screens are becoming more and more apparent.

[0003] Traditional LCD TVs and LED displays are bulky; a 65-inch LCD TV is over 145 centimeters wide and weighs over 20 kilograms. Moving them requires specialized tools and multiple people, making them difficult to transport in complex outdoor terrain. Even after being transported to the site, professional installation and setup are time-consuming and labor-intensive, severely impacting event efficiency.

[0004] While existing portable projection screens have seen improvements, their portability remains insufficient. When folded, they are approximately 30 centimeters in diameter, over 1 meter long, and weigh more than 5 kilograms; when unfolded, they take up a large area. Carrying such a screen while camping undoubtedly adds to the burden and diminishes the outdoor experience.

[0005] More importantly, neither type of device performs well outdoors. Under direct sunlight during the day, the image becomes blurry and details are lost; in the evening, ambient light interference causes a sharp drop in image contrast.

[0006] Therefore, it is necessary to provide a foldable and portable outdoor video display device to solve the above-mentioned technical problems. Utility Model Content

[0007] This invention provides a foldable and portable outdoor video display device, which solves the problems in the background technology.

[0008] To address the aforementioned technical problems, this utility model provides a foldable and portable outdoor video display device, comprising a storage box and a connecting rod. A mounting base is installed on the surface of the connecting rod, and a folding fixing rod is movably mounted inside the mounting base via a pin. A first fixing hole is formed through the surface of the folding fixing rod, and a display component is fixed to the surface of the folding fixing rod by fasteners. The display component is composed of LED displays. A second fixing hole is formed through the surface of the connecting rod, and a third fixing hole is formed on the surface of the storage box. The connecting rod is fixedly connected to the storage box via fasteners passing through the second and third fixing holes, clearly defining the connection relationship and composition of each key component. The mounting base and the folding fixing rod are movably connected via a pin, giving the device flexible folding characteristics. Users can quickly fold and store the display component along with the folding fixing rod according to actual usage scenarios and storage needs, greatly reducing the device's size and significantly improving portability. The display components are assembled from LED displays. Compared to traditional display devices, LED displays offer high brightness, high contrast, and low power consumption. They maintain clear and vibrant images even in strong outdoor light and ambient light conditions, effectively solving the problem of unsatisfactory outdoor displays from traditional devices. Meanwhile, the connecting rods, folding fixing rods, and placement box are connected by fasteners and corresponding fixing holes. This connection method not only ensures the stability of the assembled equipment, preventing it from falling apart due to wind or minor impacts during outdoor use, but also facilitates the disassembly and installation of components. This allows users to easily assemble and store the equipment, lowering the barrier to entry and enabling both professionals and ordinary users to quickly get started.

[0009] Preferably, the placement box has a first placement slot inside, where the connecting rod is placed. The placement box also has a second placement slot inside, where the display component is placed. Finally, a third placement slot inside the placement box houses the power supply device. By rationally planning the first, second, and third placement slots, the various components of the device are neatly stored. This partitioned storage method avoids mutual squeezing and collision between the connecting rod, display component, and power supply device during storage, effectively protecting the device components and extending the overall lifespan of the device. Furthermore, the clear storage layout allows users to quickly locate and retrieve the required components when using the device, significantly reducing installation and debugging time. For example, during outdoor camping activities, users can quickly find and assemble the components, rapidly setting up the display device and enjoying outdoor entertainment without spending a lot of time searching for parts in the equipment, greatly improving the user experience and activity efficiency.

This arrangement provides ample adjustment options for the installation of the display component. Users can flexibly adjust the installation position of the display component on the folding fixing rod according to the size and shape of the displayed image. For example, in small gatherings, the display component can be installed near the first fixing hole on the connecting rod to reduce screen size and save space; while in large outdoor performances, the display component can be installed away from the first fixing hole on the connecting rod to increase screen size and meet the viewing needs of more audience members. This flexible adjustment method allows the device to adapt to diverse usage scenarios, improving its versatility and practicality.

[0011] Preferably, a positioning plate is provided on the lower part of the outer surface of the placement box. A positioning hole is formed through the surface of the positioning plate, and a steel fork is inserted into the positioning hole. The positioning plate and positioning hole on the outer side of the placement box, used in conjunction with the steel fork, provide reliable assurance for the stable placement of the device in outdoor environments. When used outdoors, inserting the steel fork into the positioning hole and fixing it to the ground effectively resists the influence of wind and other external forces on the device, preventing the placement box from shifting or tipping over, and ensuring that the display device remains stable during use. Whether on flat terrain such as open grasslands or beaches, or in slightly sloping mountainous environments, this design allows the device to stand firmly, providing users with a consistently stable and clear image display, avoiding problems such as blurry images caused by device shaking, and enhancing the applicability of the device in complex outdoor environments.

[0012] Preferably, a sealing door is hinged to the outer surface of the storage box, and a handle is installed on the outer surface of the sealing door. The hinged sealing door and handle on the outside of the storage box facilitate the storage and handling of the equipment. The sealing door effectively prevents dust, rainwater, and other external debris from entering the storage box, protecting equipment components from environmental corrosion and further extending the equipment's service life.

[0013] Preferably, the bottom of the placement box is equipped with multiple pulleys, which are equidistantly installed on the bottom surface of the placement box. This equidistant distribution of pulleys greatly enhances the flexibility of the equipment during movement. Before installation, users can easily adjust the position of the equipment by pushing the placement box and using the pulleys to quickly find the optimal installation location without having to laboriously move heavy equipment. During use, temporary adjustments to the equipment's direction or position can also be easily made using the pulleys. Furthermore, the pulley design reduces friction between the equipment and the ground, minimizing wear on the bottom of the placement box and extending its service life. It also makes the overall movement of the equipment smoother and more convenient, providing a better user experience.

[0014] Compared with related technologies, the foldable and portable outdoor video display device provided by this utility model has the following advantages:

[0015] Compared to existing technologies, this device employs a folding fixing rod and connecting rod connected by a pin and secured with fasteners, allowing for flexible folding and unfolding. The first fixing hole on the surface of the folding fixing rod and the second fixing hole on the connecting rod, combined with fasteners, ensure a secure connection between the display component and the connecting rod, facilitating disassembly. For storage, the connecting rod can be separated from the storage box via fasteners passing through the second fixing hole and the third fixing hole on the storage box, allowing the folding fixing rod to be folded away, significantly reducing the overall size. Compared to the bulky and difficult-to-carry traditional LCD TVs and LED displays, and the still relatively large size of existing portable projection screens even when folded, this device occupies minimal space when folded. It requires no special tools or multiple people for transport; a single person can easily carry and move it. Whether in complex outdoor terrain or urban environments, it greatly improves the ease of movement, meeting users' needs for outdoor entertainment activities anytime, anywhere.

[0016] Compared to existing technologies, the storage box features multiple storage slots. The first slot holds the connecting rod, the second the display components, and the third the power supply. This partitioned design provides dedicated space for each component, preventing collisions and wear, effectively protecting the equipment and extending its lifespan. Furthermore, the organized storage allows users to quickly locate the required parts, improving installation and setup efficiency. For example, during outdoor camping, users can quickly retrieve components from their corresponding slots for assembly, eliminating the need to rummage through cluttered gear. Compared to the time-consuming and labor-intensive installation and setup of traditional equipment, this significantly saves time and effort, providing a smoother outdoor user experience.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

A second fixing hole 13 is formed through the surface of the connecting rod 8, and a third fixing hole is formed on the surface of the storage box 1. The connecting rod 8 is fixedly connected to the storage box 1 via fasteners passing through the second and third fixing holes, clearly defining the connection relationship and composition of each key component. The mounting base 10 and the folding fixing rod 11 are movably connected via the pin 9, giving the device flexible folding characteristics. Users can quickly fold and store the display component 4 along with the folding fixing rod 11 according to actual usage scenarios and storage needs, greatly reducing the device's size and significantly improving portability. Display component 4 is constructed from LED displays. Compared to traditional display devices, LED displays offer high brightness, high contrast, and low power consumption. They maintain clear and vibrant images even in strong outdoor light and ambient light conditions, effectively solving the problem of unsatisfactory outdoor displays in traditional devices. Meanwhile, the connecting rod 8, folding fixing rod 11, and placement box 1 are connected via fasteners and corresponding fixing holes. This connection method not only ensures the stability of the assembled device, preventing it from easily falling apart due to wind or minor impacts during outdoor use, but also facilitates the disassembly and installation of components. This allows users to easily assemble and store the device, lowering the barrier to entry and enabling both professionals and ordinary users to quickly get started.

[0027] The working principle of the foldable and portable outdoor video display device provided by this utility model is as follows:

[0028] When using this foldable and portable outdoor video display device, first remove and unfold the device.
