Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable reel technology, specifically a mechanism for the slow-pull and automatic reel storage of cables for mobile shooting vehicles. Background Technology
[0002] When using mobile filming vehicles, long-distance cables are required to power them or transmit signals. Currently, cable winding and unwinding mostly rely on motor-driven reels.
[0003] However, on filming sets, cables are often subjected to sudden external forces due to people stepping on them, equipment moving, or emergencies. This instantaneous large tension can easily damage or even break the wire core inside the cable, affecting the stability of signal transmission, and even causing equipment to lose power and interrupt filming. In addition, traditional reels are not convenient for tensioning and straightening cables. When rewinding, the cable is prone to becoming slack, resulting in a loose and messy arrangement on the reel, affecting aesthetics and subsequent use. Utility Model Content

This allows the cable to fit better against the reel, achieving neat and tight cable winding. Attached Figure Description

[0026] 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.
[0027] Please see Figures 1-7 This utility model discloses a cable slow-pull and automatic reel-up mechanism for a mobile shooting vehicle, including a shooting vehicle body 1, and further including: a buffer plate 2 disposed on one side of the top surface of the shooting vehicle body 1, a sliding plate 3 fixedly disposed on both sides of the bottom surface of the buffer plate 2, and a slow-pull assembly 4 fixedly installed on one side of the sliding plate 3; through the setting of the slow-pull assembly 4 and the buffer plate 2, the reel-up assembly 11 is used to reel in the cable. When the cable is suddenly dragged by the outside, the buffer plate 2 will squeeze the slow-pull assembly 4, so that the buffer rod 421 squeezes the buffer slider 422 and the buffer spring 423, and the damper 12 plays a damping role, buffering the external drag force and avoiding the cable breakage or damage caused by excessive instantaneous force;
[0028] A fixed frame 5 is installed on one side of the top surface of the buffer plate 2. An electric push rod A 6 is fixedly installed on one side of the fixed frame 5.

A tensioning wheel 9 is rotatably installed inside the adjustment component 8. A straightening wheel 10 is rotatably installed at the bottom of one side of the movable frame 7. With the setting of the tensioning wheel 9 and the straightening wheel 10, the cable is wound in an S-shape around the three sets of straightening wheels 10 and tensioning wheels 9. When the electric push rod B 81 is turned on, the tensioning wheel 9 is driven to rise and fall, and the cable is tensioned to different degrees. When the servo motor 111 drives the winding reel 112 to rotate and wind the cable, the tensioning wheel 9 cooperates with the straightening wheel 10 to straighten the cable, and at the same time improves the tension of the cable, so that the cable can better fit on the winding reel 112, realizing the neat and tight winding of the cable. A winding component 11 is set on the other side of the top surface of the buffer plate 2.

[0031] Specifically, the buffer assembly 42 includes a buffer rotating rod 421, a buffer slider 422, and a buffer spring 423.

Both the buffer slider 422 and the buffer spring 423 are sleeved on the surface of the limiting rod 43.
[0032] In this embodiment, when the cable is suddenly dragged by an external force, the buffer plate 2 will squeeze the pull-out assembly 4, causing the buffer rod 421 to squeeze the buffer slider 422 and the buffer spring 423, thus absorbing the dragging force.
[0033] Specifically, a buffer channel 14 is provided on the top surface of the shooting vehicle body 1, a limit groove is provided on the inner wall of the buffer channel 14, a limit rod 43 is fixedly set inside the limit groove, and a sliding plate 3 is slidably set inside the buffer channel 14.
[0034] In this embodiment, the buffer channel 14 is used to limit the buffer plate 2, and the limiting groove is used to limit the pull-out assembly 4.
[0035] Specifically, the adjustment assembly 8 includes a B electric push rod 81 and an adjustment block 82. The B electric push rod 81 is fixedly installed on the top surface of the movable frame 7, and the adjustment block 82 is fixedly installed at the output end of the B electric push rod 81.
[0036] In this implementation plan, the electric push rod 81 is opened, which drives the tensioning wheel 9 to rise and fall, thus tensioning the cable to different degrees.
[0037] Specifically, the winding assembly 11 includes a servo motor 111 and a winding reel 112. The servo motor 111 is fixedly installed on the top surface of the buffer plate 2, and the winding reel 112 is fixedly installed at the output end of the servo motor 111.
[0038] In this embodiment, the servo motor 111 drives the winding reel 112 to rotate, winding up the cable for the mobile shooting vehicle.
[0039] Specifically, a support frame 13 is rotatably mounted on one side of the winding reel 112, and the support frame 13 is fixedly installed on the top surface of the buffer plate 2.
[0040] In this embodiment, the support frame 13 is used to support the winding reel 112.
[0041] Specifically, a damper 12 is fixedly installed in the middle of one side of the sliding plate 3, and one side of the damper 12 is fixedly connected to the buffer channel 14.
[0042] In this embodiment, the damper 12 is used to dissipate the energy stored in the pull-out assembly 4.
[0043] Specifically, there are three sets of straightening wheels 10, which are distributed sequentially along the axial direction.
[0044] In this implementation scheme, the straightening wheel 10 works in conjunction with the tensioning wheel 9 to straighten and tension the cable.
[0045] Specifically, there are four slow-release components 4, which are arranged in two symmetrical groups.
[0046] In this embodiment, the tension buffer 4 is used to buffer the sudden force on the cable.
[0047] The working principle and usage process of this utility model are as follows: The cable is wound in an S-shape around three sets of straightening rollers 10 and tensioning rollers 9. The electric push rod B is turned on, which drives the tensioning rollers 9 to rise and fall, thus tensioning the cable to different degrees. When the servo motor 111 drives the winding reel 112 to rotate and wind up the cable, the tensioning rollers 9 cooperate with the straightening rollers 10 to straighten the cable and also increase the tension of the cable, so that the cable can fit better on the winding reel 112, achieving neat and tight cable winding.
[0048] The connecting block 41 is used to connect the slow-pull assembly 4 to the sliding plate 3. The limiting rod 43 is used to limit the buffer group 42. When the cable is suddenly dragged by the outside, the buffer plate 2 will drive the sliding plate 3 to squeeze the slow-pull assembly 4, so that the buffer rotating rod 421 squeezes the buffer slider 422 and the buffer spring 423 to absorb the dragging force. The damper 12 plays a damping role and buffers the external dragging force, avoiding the cable from breaking or being damaged due to excessive instantaneous force.
