And the wire harness is prevented from being damaged.

Description

Technical Field

[0001] The utility model relates to the field of spherical LED display screens, in particular to a spherical LED display screen. Background Art

[0002] The spherical LED display screens commonly seen on the market currently usually adopt a suspended design. This type of display screen is mainly composed of a spherical grid, multiple arc-shaped flexible display modules, and key components such as a controller. Among them, the arc-shaped flexible display module is firmly fixed on the spherical grid by adsorption. In order to ensure the normal operation of the display screen, each arc-shaped flexible display module is closely connected to the controller through a wire harness. However, these wire harnesses must be threaded through the preset hollow holes on the spherical grid.

[0003] Since the spherical grid usually adopts an integrated design, the size of its hollow holes is strictly limited. In addition, there are a large number of wire harnesses, and each wire harness is equipped with various connector plugs, which increases the risk of entanglement between wire harnesses. Once a circular arc-shaped flexible display module fails or is damaged, technicians need to carefully pull the wire harness out of the narrow hollow hole during maintenance. This process is not only difficult to operate, but also very likely to cause damage to the wire harness or connector plug.

[0004] Therefore, it is necessary to provide a spherical LED display screen to solve the above technical problems. Utility Model Content

[0015] Preferably, when the wire tube is in a vertical state, the mounting frame is in a horizontal state.

[0016] Compared with the related art, the utility model provides the following beneficial effects:

[0017] When the spherical LED display screen of the utility model needs to unfold the spherical structure for maintenance, the linear drive structure will drive the mounting plate to move upward until the steel wire rope is in a straight straight state. Since the spring is in a compressed state at this time, the steel wire rope connected thereto is also in a tight state. Under the elastic force of the spring, the slide bar will slide outward along the sleeve, so that a gap is formed between adjacent arc-shaped frames. There is also a large gap at the top and bottom of the unfolded spherical LED display screen, and this gap is relatively large compared to the size of the hollow holes on the existing spherical grid, so that it is convenient for technicians to perform maintenance operations and avoid damage to the wiring harness.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] Please refer to Figures 1 to 5 A spherical LED display screen includes a mounting frame 1, and a plurality of sleeves 2 are provided at equal angles on the side wall thereof. A sliding rod 3 that can slide is embedded at one end of each sleeve 2, and a spring 4 is installed inside the sleeve 2. The two ends of the spring 4 are in contact with the sliding rod 3 and the mounting frame 1, respectively, to provide power for the expansion and closing of the display screen.

[0026] An arc-shaped frame 5 is fixed to the end of the slide bar 3 away from the sleeve 2. When a plurality of such arc-shaped frames 5 are arranged around the mounting frame 1, they together form a complete spherical structure. An arc-shaped flexible display module 6 is mounted on the outer wall of each arc-shaped frame 5, and these modules together constitute the display surface of the display screen.

[0027] For the convenience of maintenance, a linear drive structure 7 is installed on one side of the mounting frame 1, and a mounting plate 8 is fixed at its output end. It should be noted that the linear drive structure 7 can adopt existing mechanisms such as an electric push rod with self-locking. When the spherical structure needs to be unfolded for maintenance, the linear drive structure 7 will drive the mounting plate 8 to move upward. Since the spring 4 is in a compressed state at this time, the wire rope 11 connected thereto is also in a taut state. Under the elastic force of the spring 4, the slide rod 3 will slide outward along the sleeve 2, so that a gap is formed between adjacent arc-shaped frames 5, thereby facilitating maintenance operations for technicians.

[0028] On the contrary, when the spherical structure needs to be closed, the linear drive structure 7 will drive the mounting plate 8 to move downward, thereby dragging the wire rope 11. In this process, the spring 4 will be gradually compressed, and the wire rope 11 will also move along the preset channel 10. In this way, the slide rod 3 will slide inward along the sleeve 2, so that the adjacent arc-shaped frames 5 are close to each other, and finally a tight spherical structure is re-formed.

[0029] In addition, the design of this display screen also takes into account the stability and convenience of module fixation. The back of the arc-shaped flexible display module 6 is provided with a rubber magnetic layer, which can be fixedly connected to the iron arc-shaped frame 5 by magnetic adsorption. At the same time, a positioning column 13 is also provided on the back of the module, which cooperates with the positioning groove 14 on the arc-shaped frame 5 to further ensure the installation accuracy and stability of the module.

[0030] It is worth mentioning that a wire tube 12 is fixed to the end of the linear drive structure 7. This wire tube not only extends to the outside of the spherical structure, but also allows the wires and hanging ropes to pass through its interior. This design not only protects the wires from damage, but also facilitates the hanging of the display screen. When the wire tube 12 is in a vertical state, the mounting frame 1 is naturally in a horizontal state, thereby ensuring the stability and balance of the entire spherical structure.

[0031] Working principle:

[0032] Spherical structure unfolding process: The linear drive structure 7 drives the mounting plate 8 to move upward, and the mounting plate 8 is connected to the wire rope 11, such as Figure 4 The mounting plate 8 shown is moved until the wire rope 11 is in a straightened state as a whole (i.e., the sliding trajectory of the wire rope 11 is consistent with that of the slide rod 3). Since the spring 4 is in a compressed state, the wire rope 11 is in a straightened state. Under the elastic force of the spring 4, the slide rod 3 slides outward along the sleeve 2, and a gap is formed between adjacent arc-shaped frames 5, which is convenient for maintenance.

[0033] The closing process of the spherical structure: the mounting plate 8 is driven downward by the linear drive structure 7, and the mounting plate 8 drags the wire rope 11. The wire rope 11 is in a bent state, the spring 4 is gradually compressed, and the wire rope 11 moves along the channel 10. The slide rod 3 slides inward along the sleeve 2, so that the adjacent arc-shaped frames 5 are close to each other, and finally the spherical structure is re-formed.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
