Description

Technical Field

[0001] The present invention relates to the technical field related to display screens, and in particular to a distributed intelligent display control device. Background Art

[0002] LED display screens integrate microelectronics technology, computer technology, and information processing, and have the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation, etc. LED display screens are widely used in commercial media, cultural performance markets, stadiums, information dissemination, news releases, securities trading, etc., and can meet the needs of different environments. LED display screens are also widely used in exhibition venues.

[0003] However, most of the existing LED display screens are fixed structures, and the viewing angle remains unchanged. In order to clearly see the playback image, people need to walk to a position facing the screen to watch. The exhibition effect is average, and the interaction between the display screen and people is poor. In terms of human-computer interaction, people are often limited to simple viewing and acceptance, and cannot form effective interaction with the display screen. At the same time, the existing display screens are always playing regardless of whether there is someone in front of the screen, which is more power-consuming and energy-consuming.

[0004] Therefore, there is an urgent need for a distributed intelligent display control device to solve the above defects. Summary of the invention

[0005] 1. Technical solution

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a distributed intelligent display control device, comprising a base, wherein support frames are symmetrically installed at the left and right ends of the base, the upper end of the support frame is rotatably connected to the outer frame, and a display screen is installed inside the outer frame.

[0007] A power supply module is provided at the lower end of the outer frame, and the power supply module supplies power to the display screen. The power supply module and the pedal assembly are connected through a linkage module, and the linkage module is installed on a sliding block. The sliding block is set on a support frame for sliding up and down. A rotatable pedal assembly is provided between the sliding blocks, and a connecting frame is installed at the lower end of the sliding block. A locking piece is connected between the pedal assembly and the connecting frame, and the locking piece is connected with a locking groove provided in the support frame. The locking piece is used to control the angle adjustment of the pedal assembly, and a connecting spring is connected between the connecting frame and the base.

[0008] Specifically, a person steps on the pedal assembly (only one person can walk on a single pedal assembly at a time), and the pedal assembly as a whole drops vertically and then the angle is adjusted. After the pedal assembly drops, the power supply module supplies power to the display screen, and the display screen plays the picture after being powered on. After the angle of the pedal assembly is adjusted, the display screen is adjusted horizontally under the action of the linkage module, so that the screen of the display screen is facing the position of the person. As the person walks, the screen of the display screen always faces the walking person. This application is designed for the power-on state and angle adjustment of the display screen. The display screen is not powered off when the person has not arrived at the viewing area. When the person arrives at the viewing area, the display screen is powered on and the direction of the display screen always follows the walking person.

[0009] The pedal assembly includes a rotating shaft, a pedal, and a return spring. A rotating shaft is rotatably arranged between the sliding blocks, and a pedal is installed on the rotating shaft. A return spring is connected between the front and rear ends of the pedal and the connecting frame. The return springs on both sides of the pedal always tend to elastically push the pedal upward. When a person does not step on the pedal, the return springs on both sides elastically return the angle-adjusted pedal to a horizontal state.

[0010] The linkage module includes bevel gear 1, bevel gear 2, a connecting shaft, gear 1, gear 2, and a rotating column. Bevel gear 1 is installed at the end of the rotating shaft, bevel gear 2 meshing with bevel gear 1 is installed at the lower end of the connecting shaft, gear 1 is installed at the upper end of the connecting shaft rotatably connected to the sliding block, gear 2 meshing with gear 1 is installed at the lower end of the rotating column, and the rotating column rotatably connected to the upper end of the sliding block is installed at the lower end of the power supply module.

[0011] Specifically, when a person steps on the pedal, the pedal is adjusted in angle after vertically descending for a period of time (the direction of the angle adjustment is the position of the foot). At this time, the rotating pedal drives the rotating shaft to rotate synchronously, and with the cooperation of bevel gear one, bevel gear two and gear one, gear two, the outer frame and the display screen are adjusted in angle toward the position of the person, so that the screen position of the display screen is facing the person.

[0012] As a preferred technical solution of the present invention, the power supply module includes a shell, a battery, a trigger switch, and a sliding part. The shell is installed at the lower end of the outer frame. The battery and trigger switch arranged inside the shell are electrically connected to the display screen. The sliding part that cooperates with the trigger switch for extrusion is arranged inside the shell and slides up and down. The rotating column is installed at the lower end of the sliding part.

[0013] As a preferred technical solution of the present invention, the trigger switch includes a conductive block, a reset spring, a contact block, and an insulating rod. The conductive blocks are symmetrically installed inside the shell, and the insulating rods located between the conductive blocks are slidable up and down inside the shell. The upper end of the insulating rod is installed with a contact block, and a reset spring is connected between the contact block and the fixed block inside the shell. The reset spring always maintains a tendency to push the insulating rod downward, and the surface of the reset spring is coated with an insulating layer.

[0014] As a preferred technical solution of the present invention, the sliding part has a square column structure, and the cross-section of the sliding part is a T-shaped structure. The setting of the sliding part controls the switching condition of the trigger switch on the one hand, and on the other hand, when the sliding part rotates horizontally, the shell needs to rotate synchronously. The design of the square column structure ensures the synchronous horizontal rotation of the shell and the sliding part. A smooth layer is provided on the upper end of the sliding part. The setting of the smooth layer reduces the wear when contacting the insulating rod.

[0015] Specifically, after the pedal assembly drops vertically, it drives the sliding block to drop synchronously. At this time, the sliding part also drops. After the lower end of the insulating rod is not resisted, the contact block and the insulating rod drop as a whole under the action of the reset spring, so that the contact block contacts the conductive block. At this time, a complete path is formed between the battery, the trigger switch and the display screen. The display screen plays the picture after being powered on. The power-on status of the display screen depends on whether the pedal assembly is dropped. When a person steps on the pedal assembly (the person arrives at the viewing area), the display screen is powered on to play.

[0016] As a preferred technical solution of the present invention, the locking member includes a rotating shaft, a linkage belt, and a clamping block. A rotating shaft is rotatably arranged between the connecting frame and the connecting plate, a linkage belt is connected between the rotating shaft and the rotating shaft, and a clamping block is installed at the outer end of the rotating shaft.

[0017] As a preferred technical solution of the present invention, the snap-fit ​​block is snapped into the locking groove, the locking groove is composed of a snap-fit ​​groove and an unlocking groove connected up and down, the width of the snap-fit ​​groove is equal to the width of the snap-fit ​​block, the width of the unlocking groove is greater than the width of the snap-fit ​​groove, and the snap-fit ​​block in the initial position is snapped into the snap-fit ​​groove.

[0018] Specifically, when a person steps on the pedal, the locking block is locked in the locking groove (the structures between the two are matched, and the locking block can only slide vertically downward at this time), the rotating shaft cannot rotate, and the pedal drops vertically. When the locking block is locked in the unlocking groove, since the width of the locking groove is equal to the width of the locking block, the unlocking groove no longer locks the locking block. At this time, the rotating shaft can rotate, and the pedal is adjusted with the angle (the rotation direction of the angle is affected by the gravity of the person).

[0019] As a preferred technical solution of the present invention, an anti-skid layer is provided on the upper surface of the pedal to achieve an anti-skid effect.

[0020] 2. Beneficial Effects

[0021] 1. A distributed intelligent display control device described in the present invention is designed for the power-on state and angle adjustment of the display screen. When a person has not arrived at the viewing area, the display screen is not powered off. When the person arrives at the viewing area, the display screen is powered on and the display screen always follows the walking person under the action of structural linkage, so that the interaction between the person and the machine is improved while the person is watching the screen, and the display screen circuit is controlled, which increases the fun and saves the electricity bill.

[0022] 2. In the distributed intelligent display control device described in the present invention, the power supply module cooperates with the pedal assembly to control whether the display screen is powered on. After a person steps on the pedal assembly, the pedal assembly as a whole drops vertically, and at this time, the sliding block and the sliding member drop synchronously. After the lower end of the insulating rod is not resisted, the contact block and the insulating rod drop as a whole under the action of the reset spring, so that the contact block contacts the conductive block. At this time, a complete path is formed between the battery, the trigger switch and the display screen, and the display screen plays the picture after being powered on;

[0023] 3. In a distributed intelligent display control device described in the present invention, a linkage module and a pedal assembly cooperate with each other to control the horizontal rotation angle of a display screen. After a person steps on the pedal, the pedal is adjusted in angle after vertically descending for a period of time. At this time, the rotating pedal drives the rotating shaft to rotate synchronously. With the cooperation of bevel gear 1, bevel gear 2 and gear 1, gear 2, the angle of the outer frame and the display screen is adjusted toward the position of the person, so that the screen position of the display screen is facing the person, thereby increasing the interactivity between man and machine.

[0032] The embodiments of the present invention are described below with reference to the accompanying drawings. In the process, in order to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0033] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0034] like Figures 1 to 7 As shown, a distributed intelligent display control device includes a base 1, and support frames 2 are symmetrically installed on the left and right ends of the base 1. The upper end of the support frame 2 is rotatably connected to an outer frame 3, and a display screen 4 is installed inside the outer frame 3.

[0035] A power supply module 5 is provided at the lower end of the outer frame 3, and the power supply module 5 supplies power to the display screen 4. The power supply module 5 is connected to the pedal assembly 6 through a linkage module 7. The linkage module 7 is installed on a sliding block 8. The sliding block 8 is slidably arranged on the support frame 2. A rotatable pedal assembly 6 is provided between the sliding blocks 8. A connecting frame 9 is installed at the lower end of the sliding block 8. A locking member 10 is connected between the pedal assembly 6 and the connecting frame 9. The locking member 10 is connected to a locking groove 11 provided on the support frame 2. The locking member 10 is used to control the angle adjustment of the pedal assembly 6. A connecting spring 12 is connected between the connecting frame 9 and the base 1.

[0036] Specifically, a person steps on the pedal assembly 6 (a single pedal assembly 6 can only support one person walking at a time), and the pedal assembly 6 is vertically lowered as a whole and then the angle is adjusted. After the pedal assembly 6 is lowered, the power supply module 5 supplies power to the display screen 4, and the display screen 4 plays the picture after being powered on. After the angle of the pedal assembly 6 is adjusted, the display screen 4 is horizontally adjusted under the action of the linkage module 7, so that the screen of the display screen 4 is facing the position of the person. As the person walks, the screen of the display screen 4 is always facing the walking person. The present application is designed for the power-on state and angle adjustment of the display screen 4. When the person has not arrived at the viewing area, the display screen 4 is not powered off. When the person arrives at the viewing area, the display screen 4 is powered on and the direction of the display screen 4 always follows the walking person.

[0037] The pedal assembly 6 includes a rotating shaft 61, a pedal 62, and a return spring 63. The rotating shaft 61 is rotatably arranged between the sliding blocks 8, and the pedal 62 is installed on the rotating shaft 61. The return spring 63 is connected between the front and rear ends of the pedal 62 and the connecting frame 9. The return springs 63 on both sides of the pedal 62 always tend to elastically push the pedal 62 upward. When a person does not step on the pedal 62, the return springs 63 on both sides elastically return the angle-adjusted pedal 62 to a horizontal state. The upper surface of the pedal 62 is provided with an anti-slip layer to achieve an anti-slip effect.

[0038] The linkage module 7 includes a bevel gear 1 71, a bevel gear 2 72, a connecting shaft 73, a gear 1 74, a gear 2 75, and a rotating column 76. The bevel gear 1 71 is installed at the end of the rotating shaft 61, the bevel gear 2 72 meshing with the bevel gear 1 71 is installed at the lower end of the connecting shaft 73, the upper end of the connecting shaft 73 rotatably connected to the sliding block 8 is installed with a gear 1 74, the gear 2 75 meshing with the gear 1 74 is installed at the lower end of the rotating column 76, and the rotating column 76 rotatably connected to the upper end of the sliding block 8 is installed at the lower end of the power supply module 5.

[0039] Specifically, when a person steps on the pedal 62, the pedal 62 is adjusted in angle after vertically descending for a period of time (the direction of the angle adjustment is the position of the foot). At this time, the rotating pedal 62 drives the rotating shaft 61 to rotate synchronously, and with the cooperation of bevel gear 1 71, bevel gear 2 72 and gear 1 74 and gear 2 75, the outer frame 3 and the display screen 4 are adjusted in angle toward the position of the person, so that the screen position of the display screen 4 is facing the person.

[0040] In another embodiment provided by the present invention, further, the power supply module 5 includes a shell 51, a battery 52, a trigger switch 53, and a sliding member 54. The shell 51 is installed at the lower end of the outer frame 3. The battery 52 and the trigger switch 53 arranged inside the shell 51 are electrically connected to the display screen 4. The sliding member 54 that is squeezed and matched with the trigger switch 53 is slid up and down inside the shell 51, and the rotating column 76 is installed at the lower end of the sliding member 54.

[0041] Furthermore, the trigger switch 53 includes a conductive block 531, a return spring 532, a contact block 533, and an insulating rod 534. The conductive block 531 is symmetrically installed inside the shell 51. The insulating rod 534 located between the conductive blocks 531 is slidably arranged inside the shell 51. The upper end of the insulating rod 534 is installed with a contact block 533. A return spring 532 is connected between the contact block 533 and the fixed block inside the shell 51. The return spring 532 always keeps a downward push on the insulating rod 534. The surface of the return spring 532 is coated with an insulating layer. The sliding member 54 has a square column structure, and the cross-section of the sliding member 54 is a T-shaped structure. The setting of the sliding member 54 controls the switching condition of the trigger switch 53 on the one hand, and on the other hand, when the sliding member 54 rotates horizontally, the shell 51 needs to rotate synchronously. The design of the square column structure ensures that the shell 51 and the sliding member 54 rotate horizontally synchronously. A smooth layer is provided on the upper end of the sliding member 54. The setting of the smooth layer reduces the wear when contacting with the insulating rod 534.

[0042] Specifically, after the pedal assembly 6 drops vertically, it drives the sliding block 8 to drop synchronously. At this time, the sliding member 54 also drops. After the lower end of the insulating rod 534 is not resisted, the contact block 533 and the insulating rod 534 drop as a whole under the action of the return spring 532, so that the contact block 533 contacts the conductive block 531. At this time, a complete path is formed between the battery 52, the trigger switch 53 and the display screen 4. The display screen 4 plays the picture after being powered on. The power-on state of the display screen 4 depends on whether the pedal assembly 6 drops. When a person steps on the pedal assembly 6 (the person arrives at the viewing area), the display screen 4 is powered on to play.

[0043] Furthermore, the locking member 10 includes a rotating shaft 101, a linkage belt 102, and a clamping block 103. The rotating shaft 101 is rotatably arranged between the connecting frame 9 and the connecting plate, and the linkage belt 102 is connected between the rotating shaft 101 and the rotating shaft 61. The clamping block 103 is installed at the outer end of the rotating shaft 101, and the clamping block 103 is clamped in the locking groove 11. The locking groove 11 is composed of a clamping groove and an unlocking groove connected up and down. The width of the clamping groove is equal to the width of the clamping block 103, and the width of the unlocking groove is greater than the width of the clamping groove. The clamping block 103 in the initial position is clamped in the clamping groove.

[0044] Specifically, when a person steps on the pedal 62, since the clamping block 103 is clamped in the clamping groove (the structures between the two are matched, and the clamping block 103 can only slide vertically downward at this time), the rotating shaft 61 cannot rotate, and the pedal 62 drops vertically. When the clamping block 103 is clamped in the unlocking groove, since the width of the clamping groove is equal to the width of the clamping block 103, the unlocking groove no longer clamps the clamping block 103. At this time, the rotating shaft 61 can rotate, and the pedal 62 is adjusted with the angle (the rotation direction of the angle is affected by the gravity of the person).

[0045] Working process:

[0046] Assemble the adjacent bases 1 so that multiple groups of the present application are assembled and connected front to back;

[0047] The personnel steps on the pedal assembly 6, and the pedal assembly 6 is vertically lowered as a whole and then the angle is adjusted;

[0048] After the pedal assembly 6 drops vertically, the power supply module 5 can supply power to the display screen 4, and the display screen 4 plays the picture after being powered on. After the angle of the pedal assembly 6 is adjusted, the display screen 4 is adjusted horizontally under the action of the linkage module 7, so that the screen of the display screen 4 is facing the position of the person. As the person walks, the screen of the display screen 4 is always facing the walking person, and the person can watch the picture played on the display screen 4.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
