Description

Technical Field

[0001] This invention relates to the field of camera pan-tilt technology, specifically to a video production camera pan-tilt device. Background Technology

[0002] The current gimbal is not well adapted to Gaode Sports' business, and there are significant pain points: First, the support is limited, and it is difficult to quickly fix iron-containing carriers such as guardrails and vehicle frames at the event site. For example, the "Colorful Yunnan" rally required additional support, which delayed the live broadcast and increased the burden.

[0003] Secondly, the adjustment is inefficient. The exciting moments of the competition are highly time-sensitive, and sudden weather changes require quick protection. The existing gimbals are slow to switch, and there have been instances of missed footage and signal loss due to moisture during the "ROC King of Cars" competition.

[0004] Third, the protection and transmission systems are disconnected. Cross-regional events need to cope with sandstorms, high temperatures, and high humidity. The fixed protective components are prone to jamming or poor sealing, causing image shake and affecting the accuracy of the live broadcast. Based on this, a new type of video production camera pan-tilt device has been developed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a video production camera pan-tilt device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a video production camera pan-tilt device, including a protective device, wherein the protective device includes a fixing plate, and the rear end of the fixing plate can be fixedly connected to an iron-containing magnetic adsorption surface to achieve stable support for the entire device;

[0007] A pushing device is connected to the groove on the inner surface of the fixed plate. The pushing device is driven by meshing transmission, thereby driving the connected component to move up and down.

[0008] The center of the pushing device is connected to the camera pan-tilt unit. When the pushing device is driven to move, it can move the camera pan-tilt unit out of its initial storage position so as to protect the outer surface of the camera pan-tilt unit in bad weather.

[0009] As a preferred embodiment of the present invention, the pushing device includes two semi-circular gears, and a first elliptical rod is fixedly connected to the top of each of the two semi-circular gears.

[0010] As a preferred technical solution of this invention, the rear ends of the two first elliptical rods are respectively connected to folding devices, the rear ends of the folding devices are movably connected to support frames, and the top of the support frames is connected to camera pan-tilt units.

[0011] As a preferred embodiment of the present invention, the tops of the two first elliptical rods are movably connected to top plates, and the rear ends of the two top plates are movably connected to second elliptical rods on both sides, and the bottoms of the two second elliptical rods are movably connected to the protruding parts of the fixed plate.

[0012] As a preferred embodiment of the present invention, the folding device includes two folding rods, the bottom of which is movably connected to the rear end protrusion of the semi-circular gear.

[0013] As a preferred embodiment of this invention, the top of each of the two folding rods is movably connected to a rotating shaft, and the rear ends of the two rotating shafts are movably connected to the protruding part of the support frame.

[0014] Compared with the prior art, the beneficial effects of this new technology are:

[0015] (1) A video production camera pan-tilt device, wherein a first elliptical rod is set on the top of a semi-circular gear. When the two semi-circular gears are driven to mesh and rotate by external power, the rotating semi-circular gears will drive the fixedly connected first elliptical rod to shift synchronously. At the same time, the first elliptical rod will push the two top plates that are movably connected at the top to unfold to both sides, and the second elliptical rods that are movable on both sides of the rear end of the top plates will also shift synchronously with the movement of the first elliptical rod, thereby playing the role of auxiliary support and limiting.

[0016] (2) A video production camera pan-tilt device, wherein the bottom of the folding rod is movably connected to the protruding part at the rear end of the semi-circular gear, the folding rod can be synchronously adjusted in the direction of movement under the drive of the semi-circular gear, and at the same time, the top of the folding rod can drive the support frame to move upward under the rotation of the rotating shaft, so that the support frame moves out of the area below the two top plates.

[0022] The technical solutions 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.

[0023] Example: Please refer to Figure 1-2 A video production camera pan-tilt device includes a protective device 1, the protective device 1 including a fixing plate 11, the rear end of the fixing plate 11 being fixedly connected to an iron-containing magnetic adsorption surface to achieve stable support for the entire device.

[0024] A pushing device 12 is connected to the groove on the inner surface of the fixing plate 11. The pushing device 12 is driven by meshing transmission, thereby driving the connected component to move up and down.

[0025] The center of the pushing device 12 is connected to the camera pan-tilt unit 13. When the pushing device 12 is driven to move, it can move the camera pan-tilt unit 13 out of the initial storage position so as to protect the outer surface of the camera pan-tilt unit 13 in bad weather.

[0026] Example 2: Based on Example 1, as follows Figure 3-4 As shown, the pushing device 12 includes two semi-circular gears 121, each of which has a first elliptical rod 122 on its top, and the top of each of the two semi-circular gears 121 is fixedly connected to the bottom of the first elliptical rod 122.

[0027] The two first elliptical rods 122 are provided with folding devices 123 at their rear end protrusions, and the two first elliptical rods 122 are connected to the bottom of the folding devices 123. The folding devices 123 are provided with support frames 124 at their rear end, and the rear end of the folding devices 123 is movably connected to the protrusions of the support frames 124. The top of the support frames 124 is connected to the bottom of the camera pan-tilt unit 13.

[0028] Each of the two first elliptical rods 122 has a top plate 125 at its top, and the tops of both first elliptical rods 122 are movably connected to the rear end of the top plate 125. Second elliptical rods 126 are provided on both sides of the rear end of each of the two top plates 125. By providing the first elliptical rods 122 on top of the semi-circular gears 121, when external power drives the two semi-circular gears 121 to mesh and rotate, the rotating semi-circular gears 121 will drive the fixedly connected first elliptical rods 122 to shift synchronously. Simultaneously, the first elliptical rods 122 will push the two top plates 125, which are movably connected at their tops, to unfold to both sides. The second elliptical rods 126, which are movably connected to the rear ends of the top plates 125, will also shift synchronously with the movement of the first elliptical rods 122, thus providing auxiliary support and limiting. Furthermore, the rear ends of both top plates 125 are movably connected to the tops of the second elliptical rods 126, and the bottoms of both second elliptical rods 126 are movably connected to the protruding portion of the fixed plate 11.

[0029] The folding device 123 includes two folding rods 1231, the bottom of which is movably connected to the rear protrusion of the semi-circular gear 121.

[0030] Both folding rods 1231 are equipped with a rotating shaft 1232 at their tops, and the tops of both folding rods 1231 are movably connected to the top of the rotating shaft 1232. By movably connecting the bottom of the folding rod 1231 to the protruding portion at the rear end of the semi-circular gear 121, the folding rods 1231 can synchronously adjust their direction of movement under the drive of the semi-circular gear 121. Simultaneously, under the rotation of the rotating shaft 1232, the tops of the folding rods 1231 can drive the support frame 124 to move upwards, causing the support frame 124 to move out of the area below the two top plates 125. Similarly, when the semi-circular gear 121 rotates in the opposite direction, the folding rods 1231 and the rotating shaft 1232 cooperate to drive the support frame 124 back to its initial position. The rear ends of the two rotating shafts 1232 are movably connected to the protruding portions of the support frame 124.

[0031] The working principle of this new invention is as follows:

[0032] During operation, the device is first fixedly connected to the iron-containing magnetic adsorption surface via the rear end of the fixing plate 11 to achieve stable support for the entire device.

[0033] Then, driven by external electricity, the two semi-circular gears 121 in the pushing device 12 mesh and rotate. Subsequently, the semi-circular gears 121 drive the first elliptical rod 122 fixedly connected to its top to shift synchronously. The first elliptical rod 122 can push the two top plates 125 movably connected to the top to unfold to both sides. At the same time, the second elliptical rods 126 movably connected to the rear sides of the top plates 125 will also shift synchronously with the movement of the first elliptical rod 122, thereby playing a role in auxiliary support and limiting. On the other hand, the protruding part at the rear end of the semi-circular gear 121 can also drive the folding rod 1231 movably connected to adjust the direction of movement synchronously.

[0034] Under the rotation of the rotating shaft 1232, the top of the folding rod 1231 will drive the support frame 124, which is movably connected to the rear end of the rotating shaft 1232, to move upward, so that the support frame 124 moves out of the area below the two top plates 125. The top of the support frame 124 is connected to the camera pan-tilt head 13, which in turn drives the camera pan-tilt head 13 out of its initial storage position so as to protect its outer surface in bad weather.

[0035] When the camera pan-tilt unit 13 needs to be retracted, the external power drives the semi-circular gear 121 to rotate in the opposite direction. The folding rod 1231 and the rotating shaft 1232 work together to drive the support frame 124 to move downwards and return to its original position. At the same time, the first elliptical rod 122 drives the top plate 125 to retract towards the center, and the second elliptical rod 126 resets accordingly, finally returning the camera pan-tilt unit 13 to its initial storage position.

[0036] 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.
