Description

Technical Field

[0001] The present invention relates to the technical field of audio and video data transmission, and in particular to an intelligent audio and video data transmission device. Background Art

[0002] In the prior art, for the storage device of audio and video data, the hard disks recording a large amount of audio and video data are directly stacked and sealed inside the hard disk box. However, this solution requires the entire storage device to be opened and then manually connected when one of the data storage hard disks needs to be used later. The operation steps of this process are cumbersome, and the storage status of multiple hard disks needs to be disturbed. It can only provide a single storage function and cannot provide efficient control assistance for the subsequent connection, transmission, heat dissipation and re-insertion of data storage processes. At present, there are storage devices on the market that can store and transmit a large number of hard disks. The storage device has the function of storing a large number of hard disks and controlling the connection of hard disk data. However, this type of device requires a lot of manual participation and has the problem of poor transmission reliability.

[0003] For example, an invention application with publication number CN119400218A proposes an audio-visual data storage device, which relates to the field of data storage technology and includes a storage device body, wherein the storage device body includes a storage bin, an air cooling component, a positioning mechanism and a transmission component, wherein a plurality of plug-in channels are provided inside the storage bin, a partition is inserted at the top of the plug-in channel, a guide cavity is provided at the top of the partition, a heat dissipation mechanism is embedded at the bottom of the guide cavity, a cover plate is hingedly provided on the outer side of the plug-in channel, an outer air outlet is provided on the surface of the cover plate, and a lifting channel is provided at the inner rear end of the storage bin. The audio-visual data storage device improves the uniformity of data management, and controls the heat dissipation mechanism in linkage with the help of a switching mechanism, so as to quickly connect audio-visual data hard disks at any position and provide targeted heat dissipation treatment, and also provides a clamping effect in the connected state, thereby improving the stability and reliability during the connection and transmission process.

[0004] However, the above-mentioned prior art still has some shortcomings when in use: 1. The intelligent automation is relatively low. Specifically, when it is necessary to extract data from one of the hard disks, it is necessary to manually press the hard disk to plug it into the transmission component, and it is also necessary to manually unplug the hard disk after use, which requires a lot of manual work; 2. The transmission component provided in the above-mentioned prior art has the function of up and down movement. In actual use, the transmission component needs to be equipped with a data cable. When the transmission component moves, the cable needs to provide a certain margin. When the transmission component moves, the cable will be pulled, so there is a problem that the cable is easy to loosen or be damaged, thereby affecting the reliability of transmission docking.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figures 1-5 , an intelligent transmission device for audio and video data, a slot frame 1 and a hard disk protection box 4, use the slot frame 1 to install both sides on the external positioning frame plate by bolts, and then weld a data transmission component close to one end of the slot frame 1 on the positioning frame plate through a cantilever, the bottom of the data transmission component is set and the plug-in slot on the hard disk, it should be noted that the data transmission component here is set in a static state, the hard disk protection box 4 is used to store the hard disk, which plays a role in protecting the hard disk, when in use, a shock-absorbing pad can be installed in the hard disk protection box 4, and then a clearance gap is opened on the hard disk protection box 4 for the plug-in slot on the hard disk to make way, and the plug-in slot on the hard disk passes through the clearance gap and extends to the outside.

[0037] In the present technical solution, a C-shaped ring 2 is arranged near the open end in the groove frame 1, and the C-shaped ring 2 and the groove frame 1 are matched for rotation and longitudinal sliding. During production, a notch is opened on the circular ring to form a C-shaped ring 2, wherein the axis of the C-shaped ring 2 coincides with the axis of its rotation. In specific implementation, it is preferred that a positioning tube 11 near the open end is fixedly connected in the groove frame 1, and a positioning sleeve 22 is fixedly connected to the inner arc wall of the C-shaped ring 2 through a support arm 21, and a rotating sleeve 23 is sleeved in the positioning sleeve 22, and the rotating sleeve 23 is sleeved on the positioning tube 11 and the two are matched for axial sliding, so that the C-shaped ring 2 has the functions of self-rotation and longitudinal movement.

[0038] Furthermore, two belt conveyors 3 are arranged opposite to each other at the open end of the C-shaped ring 2. The two belt conveyors 3 are arranged in parallel and constitute an actuator with the function of clamping and conveying the hard disk protection box 4. The upper and lower sides of the hard disk protection box 4 are fixedly connected with a resistance-increasing plate 101 near one end. When in use, the two belt conveyors 3 are located on both sides of the hard disk protection box 4 and opposite to the resistance-increasing plate 101. When the belt conveyors 3 are controlled to operate, they can realize the function of clamping and driving the hard disk protection box 4 to move forward and backward after clamping, wherein the working surface of the resistance-increasing plate 101 can be processed into a serrated state, and the rotation function of the C-shaped ring 2 can adjust the orientation of the clamped hard disk protection box 4, and when the C-shaped ring 2 moves longitudinally, it can adjust the position of the clamped hard disk protection box 4 in the longitudinal direction of the slot frame 1. In other words, it can drive the hard disk protection box 4 to move to the position where it is plugged in with the data transmission component, and then control the plugging and unplugging of the hard disk protection box 4 and the data transmission component.

[0039] Among them, a row of longitudinally evenly distributed storage slots 5 are arranged on one side of the trough-shaped frame 1 opposite to the opening. One storage slot 5 is used to store one hard disk protection box 4. The entrance and exit of the storage slot 5 face the C-shaped ring 2 and are inserted and matched with the hard disk protection box 4. When in use, when the hard disk protection box 4 clamped by the C-shaped ring 2 faces the entrance and exit of one of the storage slots 5, controlling the operation of the belt conveyor 3 can push the clamped hard disk protection box 4 forward and insert it into the storage slot 5. Then, controlling the belt conveyor 3 to rotate in the reverse direction can pull out the hard disk protection box 4 from the storage slot 5.

[0040] Among them, the specific structure of the belt conveyor 3 is that it includes a frame 31, a driving roller 32 and a driving belt 33. The driving belt 33 is a synchronous belt. Two driving rollers 32 connected by the driving belt 33 are arranged at both ends of the frame 31. A section of pressing plate 331 is arranged on the outer peripheral wall of the driving belt 33. This section of pressing plate 331 is composed of rubber strips arranged in a row, and the entire driving belt 33 is covered with the pressing plate 331 on the circumferential half circle. Thus, when the pressing plate 331 on the driving belt 33 faces the resistance increasing plate 101, the pressing plate 331 will squeeze and drive the hard disk protection box 4 to move back and forth by using the frictional force. On the contrary, the driving belt 33 and the hard disk protection box 4 are in a separated state, which is convenient for the C-shaped ring 2 to switch and transfer other hard disk protection boxes 4.

[0041] In this embodiment, a first transmission mechanism 6 for controlling the rotation and sliding of the C-shaped ring 2 is arranged on the trough-shaped frame 1. This first transmission mechanism 6 greatly reduces the dependence of the movement of the C-shaped ring 2 on the wire circuit and is convenient for the large-stroke movement of the C-shaped ring 2.

[0042] Specifically, the first transmission mechanism 6 includes a lead screw 61, a transmission nut 62 and a first gear roller 63. The lead screw 61 is sleeved in the positioning tube 11 and is rotationally arranged. The transmission nut 62 is sleeved in the lead screw 61, and a baffle 621 located at both ends of the rotating sleeve 23 is fixedly connected to its outer peripheral wall. When in use, a waist-shaped limiting hole is opened on the outer peripheral wall of the positioning tube 11, and the baffle 621 passes through the waist-shaped limiting hole. Controlling the rotation of the lead screw 61 can drive the circumferential movement of the transmission nut 62, and further drive the axial sliding of the rotating sleeve 23 through the baffle 621. The first gear roller 63 is rotatably connected to the opening end of the trough-shaped frame 1 and is meshed with the outer peripheral wall of the C-shaped ring 2. During implementation, a section of teeth meshing with the first gear roller 63 is arranged on the outer peripheral wall of the C-shaped ring 2. When the first gear roller 63 rotates, it can drive the C-shaped ring 2 to rotate. Among them, the first gear roller 63 is a straight tooth structure, and this setting is convenient for the C-shaped ring 2 to slide axially along the first gear roller 63. When in use, a first servo motor and a second servo motor for controlling the rotation of the lead screw 61 and the first gear roller 63 are installed outside the trough-shaped frame 1.

[0043] A second transmission mechanism 7 for controlling the operation of the belt conveyor 3 is provided on the trough-shaped frame 1. The operation of the belt conveyor 3 in this technical solution also greatly reduces the dependence on the guiding cable and facilitates large-stroke displacement.

[0044] Specifically, the second transmission mechanism 7 includes a portal carriage 71, a first gear 73, and a transmission assembly 74. Both ends of the transmission roller 32 are fixedly connected to a transmission shaft 321 that is rotatably connected to the frame 31. Both ends of the transmission shaft 321 are fixedly connected to the first gear 73. The portal carriage 71 is sleeved on the support arm 21 and is slidably arranged. During specific implementation, a sliding sleeve sleeving the outside of the support arm 21 can be welded to the middle of the middle beam of the portal carriage 71. The open end of the portal carriage 71 is fixedly connected to two portal plates 711 respectively located on the opposite sides of the two belt conveyors 3. One side of the portal plate 711 is meshed and matched with the adjacent first gear 73. Thus, when the portal carriage 71 is controlled to slide, the opposite teeth of the two portal plates 711 will drive the conveyor belts 33 on the two belt conveyors 3 to rotate in different directions. A limit stop 221 opposite to the open end of the C-shaped ring 2 is fixedly connected to the outer peripheral wall of the positioning sleeve 22. The function of the limit stop 221 is to control the distance that one end of the hard disk protection box 4 enters the C-shaped ring 2. The transmission assembly 74 has the function of driving the portal plate 711 to slide relative to the support arm 21.

[0045] Furthermore, the transmission assembly 74 includes a second gear roller 741, a transmission gear 742, and a rack 743. The transmission gear 742 is sleeved outside the positioning tube 11 and is rotatably connected to it. The rack 743 is fixedly arranged on one side inside the portal carriage 71 and is meshed with the transmission gear 742. The second gear roller 741 is rotatably connected inside the trough-shaped frame 1 and is meshed with the transmission gear 742. Similarly, the second gear roller 741 also has a straight-tooth structure, which facilitates the axial sliding of the transmission gear 742 relative to the second gear roller 741. During use, a third servo motor for controlling the rotation of the second gear roller 741 is installed outside the trough-shaped frame 1. When controlling the rotation of the second gear roller 741, the portal carriage 71 can be driven to move through the meshing cooperation of the transmission gear 742 and the rack 743.

[0046] In this embodiment, a row of evenly distributed partition plates 12 are fixedly connected to one side of the trough-shaped frame 1 opposite to the open end. Limiting plates 13 are fixedly connected to both sides of the partition plate 12 and on the side opposite to the partition plate 12, and are located at the upper and lower ends. The trough-shaped frame 1, the partition plate 12, and the limiting plates 13 enclose a row of storage slots 5. A flow-through notch 131 is formed on one side of the limiting plate 13. Limiting blocks 41 that can move up and down through the flow-through notch 131 are fixedly connected to both sides of the hard disk protection box 4. That is to say, the hard disk protection box 4 can be docked with the storage slot 5 from the upper and lower sides of the storage slot 5. Specifically, after the limiting block 41 passes through the flow-through notch 131 and enters the storage slot 5, when the hard disk protection box 4 is pushed towards the bottom of the storage slot 5, the hard disk protection box 4 is lifted and limited. When in use, an anti-slip and resistance-increasing rubber pad can be adhered in the storage slot 5. Heat dissipation windows 42 are formed on the upper and lower sides of the hard disk protection box 4, facilitating heat dissipation of the hard disk in the hard disk protection box 4 during use.

[0047] Embodiment 2

[0048] Please refer to Figure 1 , the difference from Embodiment 1 is that a sealing sleeve 8 is sleeved on the non-open end of the trough-shaped frame 1, and electric push rods 9 for controlling the sliding of the sealing sleeve 8 are arranged on both sides thereof. The electric push rods 9 are used to control the front and back sliding of the sealing sleeve 8 relative to the operating frame 1, aiming to block the notches on the upper and lower sides of the storage slot 5 and the heat dissipation windows 42 on the hard disk protection box 4 to prevent dust from entering the hard disk protection box 4.

[0049] Working principle: Before use, connect the servo motor in this technical solution to an external control system, and the external control system controls the operation of the servo motor through a program. When in use, a hard disk protection box 4 is stored in each storage slot 5. Among them, the C-shaped ring 2 is in a standby state. When in standby, the two belt conveyors 3 on it are located on the upper and lower sides of one of the hard disk protection boxes 4, and at the same time, the transmission belt 33 is in a state of not contacting the resistance-increasing plate 101. When it is necessary to extract the hard disk protection box 4 at other positions, control the screw 61 to rotate, and the C-shaped ring 2 longitudinally moves to the target hard disk protection box 4. At this time, control the gantry carriage 71 to move towards the hard disk protection box 4, and the two transmission belts 33 operate. When the pressing plate 331 starts to press the resistance-increasing plate 101, the hard disk protection box 4 is clamped and then moves towards the inside of the C-shaped ring 2. When it moves to a certain position, control the C-shaped ring 2 to rotate upwards so that the hard disk protection box 4 is separated from the current storage slot 5, and then control the longitudinal movement of the C-shaped ring 2 to drive the hard disk protection box 4 to move below the transmission component, and then control the transmission belt 33 to rotate in the reverse direction to plug the hard disk in the hard disk protection box 4 into the transmission component.

[0050] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
