Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a 2.4G-based athlete information LED screen. Background Art

[0002] With the rapid development of information technology and the sports industry, audiences are demanding increasingly sophisticated viewing experiences for sporting events. Real-time, accurate, and intuitive display of athlete information has become a crucial component in enhancing the viewing experience. LED screens, due to their high brightness, high definition, and low energy consumption, are widely used in sports venues. The advancement of wireless communication technology, particularly the widespread use of the 2.4GHz frequency band, has provided technical support for remote control and real-time data updates on LED screens.

[0003] For example, Chinese patent CN221121588U discloses an LED display screen module, comprising a base, a support rod fixedly connected to the upper side of the base, a support platform fixedly connected to the upper side of the support rod, a rotating member provided on the upper side of the support platform, and a mounting bracket fixedly connected to the upper side of the rotating member, which ensures that the screen can be quickly disassembled and installed when replaced, reduces the waiting time for replacing the screen, and makes installation more convenient. However, the above-mentioned LED display screen module has the following shortcomings in specific applications: first, the device has only one LED screen and cannot move horizontally, and can only be fixed in one position, which limits the viewing angle coverage of the screen.

[0034] In one embodiment, for the above-mentioned moving component 6, the moving component 6 includes a cylinder 601 arranged on the inner side of the screen module connection box 1, a circular mounting platform 602 is provided at the top of the cylinder 601, and a positioning shaft 603 is provided at the top of the circular mounting platform 602 passing through the screen module connection box 1 (in addition, in specific applications, the positioning shaft 603 is fixedly connected to the circular mounting platform 602 and the screen module connection box 1 respectively), a driving gear 604 is sleeved on the outer side of the positioning shaft 603 (in addition, in specific applications, the driving gear 604 is movably connected to the positioning shaft 603), and moving racks 605 are symmetrically provided on both sides of the driving gear 604 (in addition, in specific applications, the driving gear 604 and the moving rack 605 are meshed with each other), and the two ends of the moving rack 605 are symmetrically provided with A U-shaped movable block 606 is fixedly connected to the L-shaped connecting arm 2, and limiting blocks 607 are symmetrically arranged on both sides of the bottom end of the U-shaped movable block 606 (in addition, in specific applications, the limiting block 607 is movably connected to the limiting shaft 608), and one end of the limiting block 607 is provided with a limiting shaft 608 connected to the screen module connection box 1 (in addition, in specific applications, the limiting shaft 608 is fixedly connected to the screen module connection box 1), and the output end of the cylinder 601 is provided with a connecting block 609 (in addition, in specific applications, the top of the connecting block 609 is fixedly connected to the U-shaped movable block 606 located at one end of the driving gear 604), thereby providing horizontal movement capability of the LED screen body 4, ensuring that the screen can flexibly adjust its position according to the needs of the competition or activity, so as to better display the athlete information.

[0035] In addition, it should be noted that the U-shaped moving block 606 includes a first U-shaped moving block and a second U-shaped moving block symmetrically arranged at both ends of the driving gear 604, the moving rack located on one side of the driving gear 604 passes through the first U-shaped moving block and is fixedly connected to one end of the second U-shaped moving block, and the moving rack located on the other side of the driving gear 604 passes through the second U-shaped moving block and is fixedly connected to one end of the first U-shaped moving block.

[0036] The working principle of the moving component 6 is as follows: the cylinder 601 is the core power source of the moving component, which generates power through compressed air, and uses the output end to push the connecting block 609 to move horizontally. The positioning shaft 603 passes through the screen module connecting box 1, and is fixedly connected to the circular mounting platform 602 and the screen module connecting box 1. The driving gear 604 can rotate around the positioning shaft 603 and mesh with the moving rack 605. Through the gear rack transmission mechanism, the unidirectional linear motion of the cylinder 601 is converted into the bidirectional motion of the U-shaped moving block 606 at both ends of the moving rack 605; when the connecting block 609 moves, it drives the second U-shaped moving block located at one end of the driving gear 604 to move, thereby driving the second U-shaped moving block 606 to move.

Since the movable rack 605 movably connected at the other end of the second U-shaped movable block is fixedly connected to the first U-shaped movable block, it pushes the first U-shaped movable block to move horizontally in the opposite direction. The U-shaped movable block 606 is fixedly connected to the L-shaped connecting arm 2, and finally the cylinder 601 controls the L-shaped connecting arms 2 at both ends of the screen module connecting box 1 to move away or approach at the same time, driving the LED screen body 4 at both ends of the screen module connecting box 1 to move away or approach at the same time.
