Description

Technical Field

[0001] This invention relates to the field of audio and video acquisition technology, specifically to an audio and video acquisition and output device. Background Technology

[0002] Audio and video acquisition and output is a complete process of acquiring, processing and outputting sound and image signals through equipment. Its core is to achieve accurate acquisition and effective transmission of signals.

[0003] In existing technologies, handheld acquisition devices, being primarily acquisition units with a grip structure, cannot be adjusted for different acquisition environments. For example, with a typical grip structure, the acquisition device is usually mounted on top of it. When switching acquisition environments to acquire data from the ground, the acquisition unit cannot maintain proper contact with the ground. Furthermore, for some acquisition units, reversing the grip structure can easily cause the positions of the image and sound acquisition structures to reverse, altering the image and sound source directions, which is detrimental to subsequent audio and video output and audiovisual quality. Therefore, we propose an audio and video acquisition and output device to eliminate the aforementioned defects. Summary of the Invention

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 7 The present invention provides a technical solution: including a position adjuster 1, with handles 2 fixedly connected to the top and bottom sides of the position adjuster 1 respectively, a servo motor 3 provided in the middle of the position adjuster 1, the position adjuster 1 being electrically connected to the servo motor 3, and the output shaft of the servo motor 3 being fixedly connected to one end of a straight plate 4.

[0035] A gear 5 is rotatably mounted inside the top of the straight plate 4, and a corner connector 6 is fixedly connected to the gear 5 at the axis outside the straight plate 4.

[0036] The top of the corner code connector 6 is fixedly mounted with a controller 7, and the controller 7 is respectively provided with an image acquisition unit 8, a sound acquisition unit 9 and a display screen 10. The image acquisition unit 8 is rotatably connected to the controller 7.

[0037] The bottom of gear 5 is engaged with gear 2 11, the diameter of gear 2 11 is larger than the diameter of gear 5, and the side of gear 2 11 is engaged with rack 12 disposed inside straight plate 4, and rack 12 is slidably connected to straight plate 4.

[0038] The rack 12 passes through one side of the straight plate 4 and is fixedly connected to a guide rod 13. The guide rod 13 is slidably connected to the straight plate 4, and a trigger spring 14 is movably and elastically sleeved at the connection between the guide rod 13 and the straight plate 4.

[0039] The bottom side of the guiding rod 13 is fixedly connected with a rotating shaft 15;

[0040] On one side of the position adjuster 1 close to the straight plate 4, a special-shaped through groove 16 is provided, and the rotating shaft 15 is slidably arranged in the special-shaped through groove 16;

[0041] The special-shaped through groove 16 is set in two sections. The lower section is semicircular and is axially opposite to the connection part of the straight plate 4 and the position connector. The upper section of the special-shaped through groove 16 is vertically arranged, and the two sections of the special-shaped through groove 16 are mutually connected;

[0042] On the position adjuster 1 above the special-shaped through groove 16, a mounting plate 17 is fixedly connected. A contact guide wheel device 18 is slidably arranged on the mounting plate 17, and a stop head 19 is fixedly connected to the contact guide wheel device 18;

[0043] When it is necessary to collect at a low place below the operator's eye level area and when the collection area is close to the ground, through the servo motor 3, the straight plate 4 is controlled to rotate half a circle to one side. The rotation direction of the straight plate 4 conforms to the sliding direction of the rotating shaft 15 in the special-shaped guide groove. In the initial state, the rotating shaft 15 is located at the bottom of the special-shaped guide groove. After the straight plate 4 rotates half a circle, it带动 the controller 7, the image acquisition part 8 and the sound acquisition part 9 to rotate synchronously. After rotation, the positions of the lens of the image acquisition part 8 and the microphone of the sound acquisition part 9 are reversed, which affects the display of the collected image and causes a change in the sound source direction, affecting the output display of the later audio and video. Therefore, during the synchronous upward rotation of the rotating shaft 15, when it reaches the top of the special-shaped through groove 16, under the action of the trigger spring 14, the rotating shaft 15带动 the guiding rod 13 to bounce upward. The guiding rod 13拉动 the rack 12 to rotate the second gear 11. The second gear 11带动 the engaged first gear 5 to rotate, so that the angle code connector 6 rotates half a week to restore the positions of the controller 7, the image acquisition part 8 and the sound acquisition part 9;

[0044] On the bottom side of the contact guide wheel device 18, a locking frame 20 is provided. The locking frame 20 is in a "C" shape. On one side of the top of the locking frame 20, an inclined wedge head 21 is fixedly connected. The inclined wedge head 21 abuts against one end of the stop head 19;

[0045] On the side of the locking frame 20, two mounting brackets 22 fixedly connected to the position adjuster 1 are provided. A cylindrical spring device 23 is slidably arranged on the mounting brackets 22. The cylindrical spring device 23 includes a sleeve 231 slidably connected to the mounting brackets 22. A telescopic shaft 232 is movably arranged in the sleeve 231. A chute 233 is provided on the side of the telescopic shaft 232. The telescopic shaft 232 is connected to the sleeve 231 through the chute 233. One end of the telescopic shaft 232 is fixedly connected to the locking frame 20;

[0046] The top of the locking frame 20 has a through opening 24, one side of the contact guide wheel 18 is located in the through opening 24, and the bottom of the locking frame 20 is fixedly connected to the insert plate 25.

[0047] Below the locking frame 20, there are two spring frames 27 that are fixedly connected to the position adjuster 1. A lifting plate 28 is slidably arranged on the spring frame 27. A bottom frame 26 is fixedly connected to the top of the lifting plate 28. The bottom frame 26 is movably inserted into the insert plate 25.

[0048] The lifting plate 28 is hinged to one side of the insertion plate 25 with a hinge plate 29, and a counterweight roller 30 is fixedly connected to the end of the hinge plate 29 away from the lifting plate 28.

[0049] An electric cylinder 31 is provided on one side of the surface of the straight plate 4, and a fixing plate 32 is fixedly connected to the middle of the guide rod 13;

[0050] A side shaft 33 is fixedly connected to the side of the locking frame 20, and an inclined guide 34 abuts against the outer surface of the side shaft 33. The top of the inclined guide 34 is fixedly connected to the mounting plate 17.

[0051] The bottom of the lifting plate 28 is provided with a notch 35, and the side of the hinge plate 29 away from the counterweight roller 30 is in frictional contact with the lifting plate 28 through the notch 35.

[0052] A rubber sleeve 36 is fixedly connected to the handle 2;

[0053] When the rotating shaft 15 bounces up above the irregular through groove 16, it first contacts the bottom of the hinge plate 29, lifts the hinge plate 29 and passes through it, and then lifts the contact guide wheel 18 upward. The contact guide wheel moves to a high position, and during the upward lifting of the stop head 19 on its side, it disconnects the oblique wedge head 21 that was blocked by it. Since the internal spring of the cylindrical spring device 23 is built in, after the stop head 19 is removed, the locking frame 20 connected to the cylindrical spring device 23 pops outward under the drive of the telescopic shaft 232. The U-shaped locking frame 20 frames the rotating shaft 15 and limits the bottom of the rotating shaft 15 to limit the rotating controller 7, image acquisition unit 8 and sound acquisition unit 9 to prevent shaking during the acquisition process. After the locking frame 20 stops moving, the insert plate 25 is inserted into the bottom frame 26.

[0054] When the acquisition height needs to be switched again, the electric cylinder 31 outputs towards the fixed plate 32, pushing the fixed plate 32 to drive the guide rod 13 to compress the trigger spring 14. The rotating shaft 15 follows the guide rod 13 and first moves downwards towards the irregular through groove 16, pushing the hinge plate 29 downwards. The hinge plate 29 drives the lifting plate 28 downwards, gradually compressing the spring on the spring frame 27. During this process, the contact guide wheel 18 descends synchronously. Through the insertion state of the bottom frame 26 and the insert plate 25, it drives the locking frame 20 to move synchronously. During this process, the side shaft 33 of the locking frame 20 contacts the surface of the inclined guide frame 34, gradually causing the locking frame 20 to move towards the cylindrical spring device 23. As the telescopic shaft 232 approaches, it retracts into the sleeve 231. During this process, the wedge head 21 moves from below the stop head 19 to its side and is blocked by the stop head 19 again. The insert plate 25 is pulled out from the bottom frame 26, and at the same time, the rotating shaft 15 moves to the bottom of the vertical section of the irregular through groove 16. At this time, the servo motor 3 is started to drive the straight plate 4 to rotate, so that the straight plate 4 drives the controller 7, the image acquisition unit 8 and the sound acquisition unit 9 back to the acquisition position at eye level with the operator. During this process, the rotating shaft 15 leaves the top of the hinge plate 29. Under the action of the spring frame 27, the hinge plate 29 pushes the contact guide wheel 18 upward again, and the cylindrical spring 23 returns to its original position.

[0055] The working principle of this audio and video capture and output device is as follows:

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown:

[0057] S1: When acquiring audio and video data in the head-up area, the operator holds the bottom handle 2 of the position adjuster 1 so that the controller 7 is above, and acquires data in the head-up area.

[0058] S2: When collecting data from a low-lying area near the ground, the servo motor 3 controls the straight plate 4 to rotate half a turn, causing the component to rotate. After the rotating shaft 15 reaches the top of the irregular through groove 16, the spring 14 is triggered to restore the component's position.

[0059] S3: When the rotating shaft 15 pops up, it first lifts the hinge plate 29, then lifts the contact guide wheel 18. After the stop head 19 moves away, the locking frame 20 pops out to limit the rotating shaft 15, and the insert plate 25 is inserted into the bottom frame 26 to prevent shaking.

[0060] S4: The electric cylinder 31 pushes the component to move the rotating shaft 15 down, the locking frame 20 is reset, the insert plate 25 is pulled out, and the servo motor 3 drives the component back to the level view acquisition position.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
