Description

Technical Field

[0001] This utility model belongs to the field of VR shooting equipment technology, specifically relating to a VR close-up shooting support device. Background Technology

[0002] With the rapid development of virtual reality (VR) technology, the demand for VR content creation is growing, and VR close-up shooting is increasingly being used in film and television production, 3D product display, education and training, and virtual scene reconstruction. VR close-up shooting places extremely high demands on image stability, perspective accuracy, and equipment adjustment flexibility. On the one hand, close-up shooting needs to capture object details or close-up scene information, and any slight equipment shaking or angle shift will directly affect the immersion and clarity of the image. On the other hand, different shooting scenarios (such as multi-dimensional product display and close-up dynamic tracking) have different requirements for the horizontal and vertical angles of VR cameras, requiring the supporting device to have convenient angle adjustment capabilities.

[0003] Currently, some VR shooting support equipment on the market uses tripods to support cameras, which has the problem of limited angle adjustment: although traditional tripods can achieve basic height adjustment, the adjustment of horizontal rotation and pitch angle mostly depends on manually bending the bracket joints, which lacks a precise transmission structure. During the adjustment process, problems such as angle jamming and inaccurate positioning are prone to occur, making it difficult to meet the demand for fine control of the field of view in VR close-up shooting; although some dedicated VR support frames have angle adjustment functions, they are mostly single-dimensional adjustment, resulting in low operating efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a VR close-up shooting support device to solve the problem mentioned in the background art that some VR shooting support devices on the market support the camera with a tripod, which has great limitations in angle adjustment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a VR close-up shooting support device, including a tripod and a support base fixed to the surface of the tripod. A through hole is opened on one side of the outer wall of the support base, and a connecting column is rotatably connected in the through hole. An active bevel gear is fixed to the outside of the connecting column. A rotating column is rotatably connected in the support base. A driven bevel gear that meshes with the active bevel gear is fixed to the lower half of the outer wall of the rotating column, and a fixed base is fixed to the top of the rotating column.

[0006] An adjusting column is rotatably connected inside the fixed base. An adjusting block is fixed to the outer wall of the adjusting column. A positioning seat is fixed to the top of the adjusting block. A VR camera is placed inside the positioning seat, and a limiting seat is movably connected to the surface of the VR camera.

[0007] In a further embodiment, the bottom of the limiting seat is provided with multiple threaded holes, and a guide post is threadedly connected to the threaded holes at the bottom of the limiting seat. A cavity is provided inside the positioning seat for the guide post to move.

[0008] In a further embodiment, a limit slider is fixed at the bottom of the guide post, and a support spring for supporting the limit slider is sleeved on the outside of the guide post.

[0009] In a further embodiment, a turntable is fixed to the end face of the connecting column located outside the support base. The turntable is also provided with a threaded hole, and a fixing bolt is threaded into the threaded hole of the turntable.

[0010] In a further embodiment, one end of the adjusting column is fixed with a turntable 2, the turntable 2 is also provided with a threaded hole, and a fixing bolt 2 is threadedly connected to the threaded hole of the turntable 2.

[0011] In a further embodiment, the surface of the support base is provided with a groove, and a bubble level is fixed in the groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This VR close-up shooting support device uses a transmission structure of "active bevel gear + driven bevel gear". Rotating turntable one can drive the connecting column, rotating column and top fixed seat to rotate, so as to realize the 360° horizontal angle adjustment of the VR camera. At the same time, rotating turntable two can drive the adjustment column and adjustment block to rotate, thereby adjusting the pitch angle of the positioning seat, so as to meet the shooting needs of different directions and different angles in close-up shooting. The adjustment process is precise and easy to operate.

[0014] The positioning seat uses a combination structure of "guide column + limit slider + support spring" to provide elastic support for the limiting seat. The limiting seat can be tightly pressed against the surface of the VR camera, which can not only firmly fix the position of the camera and avoid image blurring caused by equipment shaking during shooting, but also adapt to VR cameras of different sizes through the buffering effect of the support spring, with strong compatibility. This VR close-up shooting support device can flexibly adjust the shooting angle according to shooting needs, and at the same time effectively fix the position of the VR camera.

[0028] Working principle:

[0029] The VR close-up shooting support device first unfolds the tripod 1 and places it in the shooting position. By observing the bubble level 21 on the support base 2, the height of the tripod 1 legs is adjusted so that the support device is in a horizontal state. Then, the VR camera 16 is placed in the positioning base 15. Under the elastic force of the support spring 20, the limiting base 17 above the positioning base 15 is pressed down by the cooperation of the guide column 18 and the limiting slider 19, and tightly fits the surface of the VR camera 16 to complete the fixation of the camera.

[0030] When adjusting the horizontal shooting angle, loosen the fixing bolt 6 on turntable 5, rotate turntable 5 to drive the connecting column 3 and the active bevel gear 4 to rotate. The active bevel gear 4 meshes with the driven bevel gear 9, thereby driving the rotating column 8, the top fixing seat 10, and the VR camera 16 to rotate synchronously. After adjusting to the appropriate horizontal angle, tighten the fixing bolt 6 to lock it. When adjusting the pitch shooting angle, loosen the fixing bolt 14 on turntable 13, rotate turntable 13 to drive the adjusting column 11 and the adjusting block 12 to rotate. The positioning seat 15 on the top of the adjusting block 12 and the VR camera 16 adjust the pitch angle accordingly. After reaching the target viewpoint, tighten the fixing bolt 14 to lock it, and then start the VR camera 16 for stable close-up shooting.

[0031] 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.
