Description

Technical Field

[0001] The present application relates to the technical field of broadcast vehicles, and in particular to a workbench of a broadcast vehicle. Background Art

[0002] An OB vehicle is a vehicle equipped with a television broadcasting system. It has functions such as recording and editing, and is mainly used for live video broadcasting. The OB vehicle workbench is one of the key equipment for the OB vehicle. The staff can place the broadcasting equipment on the workbench for operation. The workbench in use occupies a large space and is not convenient for recycling into the OB vehicle. At the same time, when in use, the existing OB vehicle workbench is fixed in position and cannot be moved.

[0003] The existing announcement number is CN211380148U, and the name is an adjustable workbench, which includes a base arranged in a carriage, an operating platform arranged above the base, and the operating platform is parallel to the base; an adjustment component for adjusting the position of the operating platform is arranged between the operating platform and the base, and the adjustment component includes two mutually parallel first support arms and second support arms, the first support arm and the second support arm are arranged along the width direction of the operating platform, the two ends of the first support arm are respectively hinged to the base and the operating platform, and the two ends of the second support arm are respectively hinged to the base and the operating platform; a gap is left between the first support arm and the second support arm to accommodate the mutual rotation of the first support arm and the second support arm, when the first support arm and the second support arm rotate at the same time, the operating platform moves with the rotation of the first support arm and the second support arm, and because the lengths of the first support arm and the second support arm are equal, the operating platform always remains parallel to the ground during the movement, thereby improving the stability of the operating platform when in use. When the operating platform moves in a direction away from the workbench, the distance between the operating platform and the workbench is increased, thereby increasing the activity space when the staff sits on the workbench, and improving the comfort of the staff when working. When the video broadcast vehicle is finished using and the side pull box is ready to be retracted, the staff can control the operating platform to move toward the work bench, thereby reducing the space occupied by the work platform, making it easier to place large equipment into the video broadcast vehicle and improving the convenience of storing the operating platform.

[0004] With respect to the above-mentioned related technologies, the inventors found that the above-mentioned workbench is installed in the broadcast vehicle by means of an adjustment component. During use, the adjustment component is deflected to adjust the use height and tilt direction of the workbench. However, the space in the broadcast vehicle is limited, and the area occupied by the operating platform of the above-mentioned workbench will not change with the adjustment of the adjustment component. This results in that when broadcast operations are not required, the workbench occupies a large space in the car, and the workbench cannot be flipped and folded, which is not convenient for storage and is not conducive to the compact setting of the car. Utility Model Content

[0005] In order to overcome the limited space in the existing broadcast vehicles, the operating platform area of ​​the above-mentioned workbench will not change with the adjustment of the adjustment components. This results in the workbench occupying a large space in the car when broadcast operations are not needed. The workbench cannot be flipped and folded, which is not convenient for storage and is not conducive to the compact setting of the car. The present application provides a broadcast vehicle workbench.

[0006] The present application provides a OB vehicle workbench that adopts the following technical solution:

[0007] A workbench of a broadcast vehicle comprises a carriage, a display platform and a workbench, wherein the display platform is arranged on the inner wall of the carriage, a first rotating shaft is horizontally fixed to the end of the bottom surface of the display platform away from the carriage, and a sliding frame is vertically fixed to the side of the bottom surface of the display platform away from the carriage, second rotating shafts are vertically fixed to the sides of both ends of the bottom surface of the display platform away from the carriage, and a support is vertically rotatably arranged on the second rotating shaft, the workbench is arranged at the end of the bottom surface of the display platform away from the carriage, and a first rotating drum is horizontally fixed to one end of the workbench, and the first rotating drum is rotatably connected to the first rotating shaft, a rotating plate is hinged on the bottom surface of the workbench, and a sliding block is hinged on the other end of the rotating plate, the sliding block is vertically slidably connected to the sliding frame, and a first spring is vertically fixed to the bottom surface of the sliding block, and the bottom end of the first spring is fixed to the bottom surface of the sliding frame.

[0008] By adopting the above technical solution, when the broadcast vehicle is used, the workbench is manually flipped downward on the first rotating shaft at the bottom of the display table. The flipping force and the squeezing force of the staff cause the slider at the end of the rotating plate on the workbench to slide vertically in the sliding frame, squeezing the first spring to deform, and then the rotating frame in the supporting parts at both ends of the display table is rotated outward on the second rotating shaft. The rotating frame is supported at both ends of the bottom surface of the workbench to support the workbench to maintain horizontal stability. When the broadcast vehicle is not in use, the workbench lacks downward pressure, and the deformation force of the first spring causes the slider to slide vertically upward in the sliding frame, so that the workbench can be flipped upward on the display table for storage, reducing the space occupied by the workbench in the car. The workbench can be flipped and folded for easy storage, which is conducive to the compact setting of the car.

[0009] Optionally, the support member includes a rotating frame, which is vertically arranged at one end of the display table, and a second rotating drum is vertically fixed on the rotating frame, and the second rotating drum is rotatably connected to the second rotating shaft.

[0010] By adopting the above technical solution, the rotating frame rotates and deflects on the second rotating axis of the display table, and can be expanded outward to support the workbench when in use, and on the contrary rotated inward to be stored when not in use, thereby reducing the space occupied in the car and facilitating the compact setting of the car.

[0011] Optionally, both upper and lower ends of the rotating frame are horizontally provided with sliding grooves, and a stretching frame is vertically arranged inside the rotating frame, and both upper and lower ends of the stretching frame are slidably connected in the sliding grooves of the rotating frame.

[0012] By adopting the above technical solution, the stretching frame slides horizontally in the rotating frame, which makes it easy to expand the stretching frame when unfolding outward, thereby increasing the area of ​​the supporting workbench and ensuring the stability of the supporting workbench.

[0013] Optionally, a bolt is penetrated through a horizontal thread at one end of the stretching frame close to the rotating frame, and a screw hole matching the bolt thread is provided on the horizontal thread of the rotating frame, and a roller is rotatably connected to the bottom end of the stretching frame.

[0014] By adopting the above technical solution, the stretching frame and the rotating frame slide, and when storing, the stretching frame is slid into the rotating frame and fixed with bolt threads to maintain stability, thereby reducing the occupied area, and the roller at the bottom of the stretching frame is used to support the circular deflection movement of the stretching frame.

[0015] Optionally, a guide hole plate is horizontally fixed on the vertical end face of the stretching frame away from the rotating frame, and a positioning rod is vertically slidably connected to the guide hole plate. A second spring is vertically sleeved on the positioning rod, and both ends of the second spring are respectively fixed to the bottom end of the positioning rod and the bottom surface of the guide hole plate.

[0016] By adopting the above technical solution, the positioning rod is pulled downward to squeeze the second spring to deform during use, and the positioning rod at the end of the expanded stretching frame slides on the guide hole plate and is inserted into the workbench. Under the action of the deformation force of the second spring, the stability of the positioning rod inserted in the workbench is maintained, thereby avoiding accidental contact with the stretching frame during use and causing it to slide into the rotating frame, and the limit stretching frame is expanded to support the workbench.

[0017] Optionally, a perforated plate is horizontally fixed on the bottom surface of the display table, and a pillar is vertically arranged below the perforated plate, a plug rod is vertically fixed to the top of the pillar, and the plug rod is slidably penetrated and connected in the perforated plate.

[0020] By adopting the above technical solution, the bottom fixing plate of the pillar is fixed to the bottom surface of the car by screws, supporting the display table in the car. The vibration of the car causes the insertion rod to slide vertically on the perforated plate, and the extrusion spring damping shock absorber absorbs the vibration to maintain the stability of the display table.

[0021] Optionally, screw hole seats are fixed on both sides of the display table, and studs are horizontally rotatably installed on the screw hole seats, screw groove seats are vertically fixed on both sides of the workbench, and the screw groove seats on the workbench are threadedly assembled and connected with the studs.

[0023] To summarize, the present application includes at least one of the following beneficial technical effects: when the broadcast vehicle is in use, the workbench is manually flipped downward on the first rotating shaft at the bottom end of the display table. The flipping force and the squeezing force of the staff cause the slider at the end of the rotating plate on the workbench to slide vertically in the sliding frame, squeezing the first spring to deform, and then the rotating frame in the supporting parts at both ends of the display table is rotated outward on the second rotating shaft. The rotating frame is supported at both ends of the bottom surface of the workbench to support the workbench to maintain horizontal stability. When the broadcast vehicle is not in use, the workbench lacks downward pressure, and the deformation force of the first spring causes the slider to slide vertically upward in the sliding frame, so that the workbench can be flipped upward for storage on the display table, reducing the space occupied by the workbench in the car. The workbench can be flipped and folded for easy storage, which is conducive to the compact setting of the car. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] By adopting the above technical solution, when the broadcast vehicle is used, the workbench 3 is manually flipped downward on the first rotating shaft 21 at the bottom end of the display table 2. The flipping force and the squeezing force of the staff cause the slider 33 at the end of the rotating plate 32 on the workbench 3 to slide vertically in the slide frame 22, squeezing the first spring 34 to deform, and then the rotating frame 241 in the supporting members 24 at both ends of the display table 2 is rotated outward on the second rotating shaft 23, and the rotating frame 241 is supported on both ends of the bottom surface of the workbench 3 to support the workbench 3 to maintain horizontal stability. When the broadcast vehicle is not in use, the workbench 3 lacks downward pressure, and the deformation force of the first spring 34 causes the slider 33 to slide vertically in the slide frame 22, so that the workbench 3 can be flipped upward on the display table 2 for storage, thereby reducing the space occupied by the workbench 3 in the carriage 1. The workbench can be flipped and folded for easy storage, which is conducive to the compact setting of the carriage.

[0033] Reference Figure 4 The support member 24 includes a rotating frame 241, which is vertically arranged at one end of the display table 2, and a second rotating drum 242 is vertically fixed on the rotating frame 241, and the second rotating drum 242 is rotatably connected to the second rotating shaft 23. The rotating frame 241 rotates and deflects on the second rotating shaft 23 of the display table 2, and can be expanded outward to support the workbench 3 when in use, and on the contrary, rotated inward to be stored when not in use, thereby reducing the space occupied in the carriage 1 and facilitating the compact setting of the carriage.

The stretching frame 243 slides horizontally in the rotating frame 241, which is convenient for expanding the stretching frame 243 when it is unfolded outward, increasing the area of ​​the supporting workbench 3, and ensuring the stability of the supporting workbench 3. The horizontal thread of the stretching frame 243 near the rotating frame 241 is penetrated by a bolt 245, and the horizontal thread of the rotating frame 241 is provided with a screw hole 246 that matches the thread of the bolt 245, and the bottom end of the stretching frame 243 is rotatably connected with a roller 244. The stretching frame 243 slides with the rotating frame 241, and when stored, the stretching frame 243 is slid into the rotating frame 241, and is threadedly fixed by the bolt 245 to maintain stability, thereby reducing the occupied area, and the roller 244 at the bottom end of the stretching frame 243 is used to support the circular deflection movement of the stretching frame 243. A guide hole plate 247 is horizontally fixed on the vertical end face of the stretching frame 243 away from the rotating frame 241, and a positioning rod 248 is vertically slidably connected to the guide hole plate 247. A second spring 249 is vertically sleeved on the positioning rod 248, and the two ends of the second spring 249 are respectively fixed to the bottom end of the positioning rod 248 and the bottom surface of the guide hole plate 247. During use, the positioning rod 248 is pulled downward to squeeze the second spring 249 to deform, and the positioning rod 248 at the end of the unfolded stretching frame 243 slides on the guide hole plate 247 and is inserted into the workbench 3. Under the deformation force of the second spring 249, the positioning rod 248 is inserted into the workbench 3 to maintain the stability of the workbench 3, so as to avoid accidentally hitting the stretching frame 243 during use so that it slides into the rotating frame 241, and the limited stretching frame 243 is unfolded to support the workbench 3.

When the flipped-up workbench 3 is kept stable in the later stage, the studs 28 on the screw holes 27 on both sides of the display table 2 are threadedly assembled in the screw grooves 35 on the workbench 3 to keep the stability of the flipped-up workbench 3 installed on the display table 2.

[0037] The implementation principle of a workbench of a broadcast vehicle in an embodiment of the present application is as follows: when the broadcast vehicle is used, the workbench 3 is manually flipped downward on the first rotating shaft 21 at the bottom end of the display table 2. The flipping force and the squeezing force of the staff cause the slider 33 at the end of the rotating plate 32 on the workbench 3 to slide vertically in the slide frame 22, squeezing the first spring 34 to deform, and then the rotating frame 241 in the supporting parts 24 at both ends of the display table 2 is rotated outward on the second rotating shaft 23, and the rotating frame 241 is supported on both ends of the bottom surface of the workbench 3 to support the workbench 3 to maintain horizontal stability. When the broadcast vehicle is not in use, the workbench 3 lacks downward pressure, and the deformation force of the first spring 34 causes the slider 33 to slide vertically upward in the slide frame 22, so that the workbench 3 can be flipped upward and stored on the display table 2.
