Abstract
Description
Technical Field
[0001] This utility model relates to the field of billboard technology, specifically to an LED mobile billboard. Background Technology
[0002] Billboards are a medium for conveying advertising information and are widely used in commercial activities and daily life. There are many types and forms of billboards, including illuminated signs, inkjet-painted signs, lightbox signs, bulletin board signs, pillar signs, directional signs, and promotional signs.
[0003] The patent with publication number CN114017620A discloses an LED mobile billboard, which includes an LED billboard body, an LED billboard housing base plate, a first support rod, a second support rod, a support rod positioning mechanism, a locking mechanism, a billboard flipping mechanism, a protective plate, a caster flipping mechanism, and casters. One end of the LED billboard body is welded with a buckle. The device has two forms: a housing form and a working form. In the housing form, it is small in size and can be dragged around for easy carrying. When needed, the placement and recycling operations are simple and save time.
[0004] However, the existing device involves directly rotating and supporting a metal frame with an LED display screen from the base plate for display and advertising. After the metal frame is supported, it is confined to the top of the base plate. If the base plate is not adjusted, the orientation of the LED display screen will be fixed, reducing the advertising and display effect. If the base plate is constantly adjusted, it is not only time-consuming and laborious, but the vibration generated by the constant adjustment process will also affect the normal use of the LED display screen. Therefore, a mobile LED billboard is proposed to solve the problem that existing billboards cannot display in multiple directions. Utility Model Content

[0015] (III) Beneficial Effects
[0016] 1. This LED mobile billboard uses a hinge to rotate the first and second billboards from the top of the L-shaped adjustment base to an inclined position. Then, the support plate in the groove is rotated to support the two billboards with the slot. Next, the servo motor is turned on, and the turntable in the rotating slot can drive the L-shaped adjustment base, together with the first and second billboards on the top, to rotate and display. This improves the publicity and display effect of the LED mobile billboard and solves the problem that existing billboards are difficult to display from multiple directions.
[0017] 2. When the LED mobile advertising billboard needs to be displayed and advertised, the U-shaped bracket is moved out of the second groove. During the process, the limiting slider in the limiting groove moves with the U-shaped bracket. When the U-shaped bracket is completely moved out of the second groove, the angle of the U-shaped bracket can be adjusted by using the fixing block and rotating shaft in the second rotating groove. The locking universal wheels can then be used to pull the LED mobile advertising billboard, improving the convenience of moving the LED mobile advertising billboard. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example: Please refer to Figure 1-5An LED mobile billboard includes a base 1, an L-shaped adjustment seat 2 on the top of the base 1, a first billboard 3 and a second billboard 4 on the top of the L-shaped adjustment seat 2, the first billboard 3 and the second billboard 4 being connected to the two ends of the L-shaped adjustment seat 2 by hinges, a rotating groove 5 on the top of the base 1, a turntable 6 rotatably connected to the inner cavity of the rotating groove 5, a servo motor 7 fixedly connected to the inner wall of the base 1, grooves 8 on the bottom of the first billboard 3 and the second billboard 4, a support plate 9 rotatably connected to the inner cavity of the groove 8, a slot 10 adapted to the support plate 9 on the top of the L-shaped adjustment seat 2, and a moving mechanism 11 on the outside of the base 1.
[0026] Furthermore, the turntable 6 is fixedly connected to the L-shaped adjustment seat 2, the output shaft of the servo motor 7 is fixedly connected to the turntable 6, and the base 1 and the L-shaped adjustment seat 2 are respectively equipped with batteries for the servo motor 7 and the first billboard 3 and the second billboard 4.
[0027] Furthermore, the moving mechanism 11 includes four lockable casters 111 disposed at the bottom of the base 1, and a second groove 112 is provided on the outer ring of the base 1. A moving block 113 and a U-shaped pull bracket 114 are slidably disposed in the inner cavity of the second groove 112.
[0028] Furthermore, a fixed block 115 is fixedly connected to one end of the movable block 113, and a second rotating groove 116 is provided on one end of the U-shaped bracket 114 facing the movable block 113. The fixed block 115 is located in the inner cavity of the second rotating groove 116 and is connected by a rotating shaft 117.
[0029] Furthermore, a limiting groove 118 is provided on the inner wall of the second groove 112, and a limiting slider 119 is slidably provided in the inner cavity of the limiting groove 118. The limiting slider 119 is fixedly connected to the moving block 113. When mobile display and advertising are required, the U-shaped bracket 114 is moved out of the second groove 112. During the process, in conjunction with the limiting slider 119 in the limiting groove 118, the moving block 113 moves with the movement of the U-shaped bracket 114. When the U-shaped bracket 114 is completely moved out of the second groove 112, the angle of the U-shaped bracket 114 can be adjusted by cooperating with the fixing block 115 and the rotating shaft 117 in the second rotating groove 116.

There is a gap between the turntable 6 and the bottom of the inner cavity of the rotating groove 5 and the ball 13 is in contact. Through the ball 13 in the ball groove 12, the friction between the bottom of the turntable 6 and the rotating groove 5 is reduced, ensuring the normal rotation of the L-shaped adjusting seat 2.
[0031] Furthermore, a protective pad 14 is provided on the outside of the L-shaped adjustment seat 2 to cover the boundary of the L-shaped adjustment seat 2 and prevent it from being damaged by bumps when rotating.
[0032] Working principle: When using this type of LED mobile advertising board, the first advertising board 3 and the second advertising board 4 are rotated from the top of the L-shaped adjustment base 2 to an inclined position using hinges. Then, the support plate 9 in the groove 8 is rotated to support the two advertising boards in conjunction with the slot 10. Next, the servo motor 7 is turned on, and the turntable 6 in the rotating slot 5 drives the L-shaped adjustment base 2, together with the first advertising board 3 and the second advertising board 4 on top, to rotate and display, thereby improving the publicity and display effect of this LED mobile advertising board and solving the problem that existing advertising boards are difficult to display from multiple directions. Conversely, the first advertising board 3 and the second advertising board 4 are rotated back to the top of the L-shaped adjustment base 2 to reduce the size of this LED mobile advertising board and facilitate its storage.
