Description

Technical Field

[0001] This utility model relates to the field of electronic information display technology, and in particular to an electronic information display device. Background Technology

[0002] Electronic information is a term in computer science. Its emergence is closely related to the rapid development of computer technology, communication technology, and high-density storage technology, and their widespread application in various fields. Electronic information display devices are platforms for displaying electronic information, and are display devices with various playback interfaces. Electronic information display devices can display corporate culture, information release, advertisements, and product information. Existing electronic information display devices are usually equipped with casters at the bottom, which facilitates movement. However, when maintaining stability through their own weight, they are easily tipped over by external forces, posing certain safety hazards.

[0003] For example, an electronic information display device disclosed in Chinese patent literature (publication number: CN222068085U) can be secured by setting up a reinforcement mechanism. When the moving wheels enter the base, the rising platform will lift one end of the connecting frame, and the connecting frame will rotate along the support shaft on the mounting base. The other end of the connecting frame will descend. During the descent, the support shaft will drive the suction cup frame to move to the bottom of the base. The suction cup frame will then adhere to the display surface, thereby securing the device and preventing it from tipping over due to external forces, thus preventing potential safety hazards.

[0004] However, when the suction cup holder contacts and presses against the ground, expelling the internal air, a negative pressure is created inside. This negative pressure causes the suction cup holder to adhere tightly to the ground, enhancing the stability of the device. But when the electronic information display device needs to be moved, the electric push rod pushes the platform, causing the wheels to contact the ground. During this process, the platform rises and forcibly lifts the suction cup holder. Due to the negative pressure inside the suction cup holder, there is a large suction force between it and the ground. When forcibly lifted, the suction cup holder will bear a large amount of tension and stress. Long-term exposure to such external forces will cause the material of the suction cup holder to gradually fatigue, leading to a decrease in its structural strength. Once the suction cup holder is damaged, it will not only weaken the device's anti-tipping ability and increase safety hazards, but also require additional maintenance costs and time to replace parts, affecting the normal use and working efficiency of the device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, the suction cup holder of electronic information display devices is prone to damage due to forced lifting, which not only increases maintenance costs but also affects normal use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electronic information display device includes a base, a display body is provided at the upper end of the base, a moving mechanism is provided inside the base, and the moving mechanism includes guide sleeves, the upper ends of the two guide sleeves are symmetrically distributed and fixedly connected to the inner top wall of the base.

[0008] The inner wall of the guide sleeve is movably fitted with a guide rod, the upper end of the guide rod is fixedly connected with a contraction spring, one end of the contraction spring is fixedly connected to the inner top wall of the guide sleeve, and the lower ends of the two guide rods are fixedly connected with lifting plates, and the lower ends of the lifting plates are fixedly installed with movable wheels distributed in a rectangular array.

[0009] The base has symmetrically distributed mounting plates fixedly connected to both sides. The inner walls of the mounting plates are fitted with symmetrically distributed mounting sleeves, and the lower ends of the mounting sleeves are fixedly fitted with suction cup holders.

[0010] Preferably, a servo motor is fixedly mounted on the front of the base, and a bidirectional lead screw is fixedly mounted on the output shaft of the servo motor through a coupling. One end of the bidirectional lead screw passes through the interior of the base and is rotatably connected to the inner wall of one side of the base through a bearing.

[0011] Preferably, the external thread of the bidirectional lead screw is connected to symmetrically distributed threaded blocks, and the lower end of the threaded blocks is fixedly connected to a first support, the inner wall of the first support being hinged to a support rod by a pin.

[0012] Preferably, the lower end of the support rod is hinged to a second support via a pin, and the lower ends of both second supports are fixedly connected to the upper end of the lifting plate.

[0013] Preferably, the base has symmetrically distributed air cylinders fixedly connected to its front and rear inner walls, a piston block is movably sleeved on the inner wall of the air cylinder, and a movable rod is fixedly connected to the back of the piston block.

[0014] Preferably, one end of the movable rod passes through the air cylinder and is fixedly connected to a drive block, and the lower end of the drive block is fixedly connected to the upper end of the threaded block.

[0015] Preferably, air pipes are fixedly connected to both sides of the air cylinder, one end of the air pipe passes through the base and is fixedly connected to the outside of the mounting sleeve, and a push handle is fixedly connected to the upper end of the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, a servo motor in the moving mechanism drives a bidirectional lead screw to control the movement of the threaded block, which in turn causes the support rod to swing, thus raising and lowering the base. This allows for easy switching between the contact states of the moving wheels, the suction cup frame, and the ground, satisfying both moving and fixed display needs. When a static display is required, the suction cup frame contacts the ground, and the air pipe draws air from inside the mounting sleeve to create negative pressure, causing the suction cup frame to adhere tightly to the ground. This effectively enhances the stability of the device and prevents it from tipping over due to external forces. During movement, the piston block moves, squeezing the gas into the mounting sleeve and converting the negative pressure inside the suction cup frame into positive pressure. This prevents the suction cup frame from being damaged by being forcibly lifted, thus extending its service life. Attached Figure Description

[0027] Example

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: an electronic information display device, including a base 1. The base 1 is made of high-strength alloy material, which has excellent strength and stability and can withstand various forces during the movement and fixing of the display body 2 and the entire device. Its upper end is fixedly set up with the display body 2 by precision welding or high-strength bolt connection, ensuring that the display body 2 will not shake or shift during use, and providing a stable platform for information display.

[0029] The inner top wall of the base 1 is fixedly connected with two guide sleeves 3 in a symmetrical arrangement by welding or bolting. This symmetrical arrangement design allows the lifting plate 33 to maintain balance during movement and avoid tilting. The inner wall of the guide sleeve 3 and the guide rod 31 are connected in a high-precision clearance fit. The guide rod 31 can slide smoothly in the guide sleeve 3, while the guide sleeve 3 can also play a precise guiding role for the guide rod 31, ensuring that the lifting plate 33 moves vertically up and down.

[0030] The upper end of the guide rod 31 is connected to a retraction spring 32 by welding or bolting. One end of the retraction spring 32 is fixedly connected to the inner top wall of the guide sleeve 3. The retraction spring 32 can play a role in buffering and resetting during the rising or falling of the lifting plate 33, reducing mechanical impact and extending the service life of the component. The lower ends of the two guide rods 31 are connected to the lifting plate 33 by welding or bolting.

[0031] A servo motor 38 is fixedly mounted on the front of the base 1 with screws. The output shaft of the servo motor 38 is fixedly connected to the bidirectional lead screw 39 through a high-precision coupling. This connection method can ensure the high efficiency and accuracy of power transmission. One end of the bidirectional lead screw 39 passes through the interior of the base 1 and is rotatably connected to the inner wall of one side of the base 1 through a high-precision bearing. The high-precision bearing can effectively reduce the friction when the bidirectional lead screw 39 rotates, ensuring its smooth rotation.

[0032] The front and rear inner walls of the base 1 are fixedly connected with symmetrically distributed air cylinders 314 by welding or bolting. The inner wall of the air cylinder 314 and the piston block 315 are movably sleeved by a precise sliding fit, and the piston block 315 can move flexibly inside the air cylinder 314.

[0033] The piston block 315 has a movable rod 316 connected to its back side by welding or bolting. One end of the movable rod 316 passes through the air cylinder 314 and is fixedly connected to the drive block 317. The lower end of the drive block 317 is fixedly connected to the upper end of the threaded block 310. This connection structure allows the threaded block 310 to accurately drive the piston block 315 to move within the air cylinder 314 through the drive block 317 and the movable rod 316 when the threaded block 310 moves.

[0034] Air pipes 318 are fixedly connected to both sides of the air cylinder 314 by welding or sealing. One end of the air pipe 318 passes through the base 1 and is fixedly connected to the outside of the mounting sleeve 36. This connection method can ensure smooth air flow between the air cylinder 314 and the mounting sleeve 36, and achieve precise control of the internal air pressure of the suction cup frame 37. A push handle 319 is fixedly connected to the upper end of the base 1 by welding or bolting. The design of the push handle 319 conforms to the ergonomic principle, making it convenient for the operator to apply pushing force when moving the device, making the movement process easier and more convenient.

[0035] The base 1 has symmetrically distributed mounting plates 35 fixedly connected to both sides by welding or bolting. The inner wall of the mounting plate 35 is fixedly fitted with symmetrically distributed mounting sleeves 36 by interference fit or precision bonding. The lower end of the mounting sleeve 36 is fixedly installed with a suction cup frame 37 by welding or bolting. This structural design ensures the firm connection between the suction cup frame 37 and the base 1, and also provides a stable foundation for the suction cup frame 37 to adsorb and separate from the ground.

[0036] The exterior of the bidirectional lead screw 39 is connected to the symmetrically distributed threaded blocks 310 by high-precision threads. This threaded connection method can ensure that the threaded blocks 310 move accurately along the lead screw axis when the bidirectional lead screw 39 rotates. The lower end of the threaded blocks 310 is connected to the first support 311 by welding or bolting. The inner wall of the first support 311 is hinged to the support rod 312 by a pin. The lower end of the support rod 312 is hinged to the second support 313 by a pin. The lower ends of the two second supports 313 are fixedly connected to the upper end of the lifting plate 33 by welding or bolting.

[0037] By converting the horizontal movement of the threaded block 310 into the vertical lifting motion of the lifting plate 33, and during the movement, it can effectively disperse and bear various forces, ensuring the stability and reliability of the structure.

[0038] The working process of this utility model:

[0039] Step 1: When the display is fixed, start the servo motor 38. The bidirectional lead screw 39 rotates, causing the two threaded blocks 310 to move relative to each other. The threaded blocks 310 drive the lifting plate 33 to rise, the moving wheel 34 leaves the ground, and the suction cup frame 37 contacts the ground. During this process, the threaded blocks 310 drive the movable rod 316 to move in the opposite direction through the drive block 317. The piston block 315 moves in the opposite direction inside the air cylinder 314. The air pipe 318 draws air from the inside of the mounting sleeve 36. After the suction cup frame 37 contacts the ground, it generates negative pressure, tightly adhering to the ground, increasing the stability of the device, and facilitating the static display of the display body 2.

[0040] Step two: During movement, the servo motor 38 is restarted, causing its output shaft to drive the bidirectional lead screw 39 to rotate. The bidirectional lead screw 39 drives the two threaded blocks 310 to move in opposite directions. The threaded blocks 310 drive the lifting plate 33 to descend through the first support 311, support rod 312, and second support 313, and the moving wheel 34 contacts the ground. At the same time, the threaded blocks 310 drive the movable rod 316 to move through the drive block 317. The movable rod 316 pushes the piston block 315 to move inside the air cylinder 314, squeezing the gas into the installation sleeve 36, so that the suction cup frame 37 changes from negative pressure to positive pressure, releasing the suction cup frame 37 from the ground, and the device can be moved easily.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
