Description

Technical Field

[0001] This application relates to the technical field of broadcast vans, and in particular to a broadcast van platform and a broadcast van that are easy to store. Background Technology

[0002] In the broadcasting and television industry, OB vans serve as mobile production and transmission platforms, widely used in scenarios such as sports events, outdoor performances, and on-site reporting of breaking news. The core function of an OB van is to house professional equipment such as cameras, video editing consoles, and signal transmission devices within a limited interior space, while providing a stable operating platform for staff. The workbench, as a key supporting facility within the OB van, directly impacts equipment deployment efficiency and operational safety, requiring it to simultaneously meet the dual demands of stable mounting while driving and space-saving transport and storage.

[0003] The existing workbenches inside broadcast vans are mainly fixed welded workbenches. These workbenches are directly welded to the van floor via brackets, using rigid connections to ensure no displacement during transport and prevent equipment damage from bumps and collisions. While this structure meets stability requirements, it cannot be folded and stored when not in use or during transport, occupying a significant amount of van space. Since broadcast van cabins typically have limited volume, fixed workbenches compress equipment storage and personnel movement space, making it difficult to flexibly arrange other essential equipment. This may even necessitate renting additional transport vehicles to move some equipment, increasing operating costs and potentially delaying equipment setup time for on-site reporting. Utility Model Content

[0004] In order to improve the problem that fixed welded workbenches can meet the stability requirements but cannot be folded and stored when idle or transported, occupying a lot of vehicle space, making it difficult to flexibly arrange other necessary equipment, and even requiring additional transport vehicles to transfer some equipment, increasing operating costs, and may also delay the equipment debugging time for on-site reporting, this application provides a broadcast vehicle platform and broadcast vehicle that are easy to store.

[0005] Firstly, this application provides a portable broadcasting van platform that is easy to store, employing the following technical solution: A portable broadcasting vehicle platform includes a base plate and a worktable mounted on the base plate. The worktable includes a support frame and support legs. The support legs are provided on both sides of the support frame. Multiple sets of pulley units are arranged at the bottom of the support legs. A slide rail for sliding the multiple sets of pulley units is mounted on the base plate. A track is embedded in the base plate. A flip frame is hinged to the side of the support leg near the track, and a locking member is provided on the other side. Multiple sets of guide wheel units for sliding within the track are mounted at the other end of the flip frame. The central axes of the guide wheel units and the pulley units are arranged along the same straight line. The central axes of the slide rail and the track are arranged along the same straight line. When the workbench is in the stowed state, multiple sets of pulley units slide out of the slide rail, and multiple sets of guide wheel units slide into the track, and the workbench is fixed to the track by the locking member; when the workbench is in the working state, multiple sets of guide wheel units slide out of the track, and multiple sets of pulley units slide into the slide rail, and the workbench is fixed to the slide rail by the locking member.

[0006] By adopting the above technical solution, the base plate provides the mounting foundation, ensuring the workbench is stably placed inside the broadcast van. The support frame and support legs constitute the main frame of the workbench, meeting the equipment's load-bearing requirements. The pulley unit works with the slide rail, and the guide wheel unit works with the track, forming a double sliding guide structure. Utilizing the hinged characteristics of the tilting frame, the workbench can smoothly switch between working and stowed states: during operation, the pulley unit slides along the slide rail and is fixed, providing stable support; during stowage, the guide wheel unit slides along the track and is fixed, significantly reducing the space occupied. Locking components ensure the stability of the workbench in both states, preventing shaking during broadcast van movement. Compared to traditional fixed workbenches, this structure ensures stability during operation while saving space through sliding stowage, adapting to the limited space of the broadcast van's cabin environment and improving space utilization and ease of operation.

[0007] Optionally, the substrate has a mounting groove, the track is disposed in the mounting groove, and the end of the track near the slide is provided with a first positioning hole for connecting with the locking member.

[0008] By adopting the above technical solution, the mounting groove provides installation space for the track, ensuring that the track position is fixed and avoiding displacement during sliding; the first positioning hole cooperates with the locking part to achieve rigid fixation when the worktable is in the storage state, preventing the guide wheel unit from moving inside the track when the vehicle is moving, and enhancing the stability of the storage state.

[0009] Optionally, the track includes a base plate and baffles, with baffles installed on both sides of the base plate. The base plate is installed at the bottom of the mounting groove, and the two baffles are V-shaped at the ends near the slide, with the V-shaped openings facing the slide.

[0010] By adopting the above technical solution, the base plate and baffle form a grooved track structure, which limits the guide wheel unit on both sides to prevent lateral deviation during sliding. The V-shaped opening acts as a guide, allowing the guide wheel unit to slide precisely into the track along the V-shaped slope when the worktable switches from the working state to the storage state, reducing the difficulty of manual alignment and improving the smoothness of state switching. The baffle also protects the guide wheel unit from external collisions, ensuring the long-term reliable operation of the sliding structure.

[0011] Optionally, a support plate is installed at the bottom of the support leg, and multiple sets of pulley units are arranged on the support plate. The width of the pulley unit is adapted to the internal width of the slide. The pulley unit can straddle both sides of the track and slide along both sides of the mounting groove. A mounting seat is installed on the side of the support plate close to the track. One end of the flipping frame is rotatably mounted on the mounting seat, and multiple sets of guide wheel units are arranged on the other end.

[0012] By adopting the above technical solutions, the support plate enhances the connection strength between the support legs and the pulley and guide wheel units, distributing the load-bearing pressure of the workbench; the pulley unit is adapted to the width of the slide rail, ensuring a tight fit and no wobbling during sliding; and its placement across both sides of the track allows for a smooth transition of the pulley unit during state switching. The mounting base provides a stable hinge fulcrum for the tilting frame, ensuring accurate trajectory of the guide wheel unit when rotating synchronously with the tilting frame, realizing coordinated action between the pulley unit and the guide wheel unit, and improving the overall structural stability and motion coordination.

[0013] Optionally, the flipping frame is rotatably mounted on one end of the support plate, and an extension plate is installed at the bottom of the other end, with the locking element mounted on the extension plate.

[0014] By adopting the above technical solution, the extension plate extends the installation position of the locking component, making it easier to align the locking component with the first positioning hole and the second positioning hole, and reducing the difficulty of operation; the flipping frame and the locking component are located at both ends of the support plate, forming a symmetrical force structure, ensuring that the force on both sides is balanced when the workbench is fixed, avoiding tilting or deformation caused by unilateral force, and enhancing structural stability.

[0015] Optionally, the end of the slide away from the track is provided with a second positioning hole for connection with the locking member.

[0016] By adopting the above technical solution, the second positioning hole cooperates with the locking component to fix the worktable when it is in operation, preventing the worktable from sliding during operation; the second positioning hole and the first positioning hole correspond to two working states respectively, forming a complete positioning system to ensure that the worktable can be stably locked in any state, meeting the dual needs of broadcast vehicle operation and transportation.

[0017] Optionally, the workbench further includes a desktop, which is hinged to one side of the support frame, and a connector for fixing the desktop is provided on one side of the support frame.

[0018] By adopting the above technical solution, the desktop hinge structure achieves a folding function, which can be folded up to fit the support frame when not in use, further reducing space occupation; the connectors fix the desktop during operation, ensuring the desktop is horizontal and stable, meeting the needs of equipment placement and operation. The folding setting and sliding storage form a dual space optimization, maximizing the storage efficiency of the workbench and adapting to the compact space layout of the broadcast van.

[0019] Optionally, the base plate includes a fixed plate and a folding plate, the fixed plate is folded and connected to the folding plate by multiple sets of hinges, the track is disposed on the fixed plate, and the slide is mounted on the folding plate.

[0020] By adopting the above technical solution, the folding structure of the fixed plate and the folding plate allows the substrate to be adjusted in terms of unfolded area as needed: the folding plate unfolds during operation to provide support for the slide; the folding plate folds up during storage to further reduce the overall space occupied by the substrate, and the hinge connection ensures smooth folding action.

[0021] Secondly, this application provides a broadcast vehicle, which adopts the following technical solution: A broadcast van includes a foldable broadcast van platform as described in any of the above embodiments, and also includes a floor, wherein the base plate of the foldable broadcast van platform is mounted on the floor.

[0022] By adopting the above technical solution, the operating device is installed on the floor of the broadcast van, achieving an integrated layout of the workbench and the van body. During operation, it provides a stable operating platform, meeting the needs of equipment deployment and personnel work. When stored, its sliding and folding mechanisms significantly reduce space, freeing up room for other equipment and personnel movement, thus adapting to the mobile operation characteristics of the broadcast van. The fixed connection between the device and the floor ensures overall stability during travel, preventing equipment damage caused by component movement and improving the operational safety and space utilization efficiency of the broadcast van.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. This working device forms a double sliding guide structure through the cooperation of pulley unit and slide rail, and guide wheel unit and track, which realizes efficient switching between the working table and the transportation and storage state. It not only ensures stable support during operation, but also saves a lot of space through storage, solving the problem of large space occupation of traditional fixed working tables, improving the space utilization of the broadcast vehicle, eliminating the need to rent additional transport vehicles to transfer some equipment, reducing operating costs, and ensuring the equipment debugging time for on-site reporting. 2. The base plate of the track provides a supporting surface, the baffle limits the sliding trajectory, and the V-shaped opening achieves a smooth transition. Together, these three elements ensure that the guide wheel unit can slide into the track accurately and smoothly and bear stable load, providing a reliable structural guarantee for the workbench in its stored state.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] Example 1 This application discloses a portable broadcast vehicle platform that is easy to store, referring to... Figure 1 and Figure 2 The easily foldable broadcast van platform includes a base plate 1 and a worktable 2 mounted on the base plate 1. The worktable 2 includes a support frame 22 and support legs 23. Support legs 23 are provided on both sides of the support frame 22. Multiple sets of pulley units 24 are arranged at the bottom of the support legs 23. A slide rail 121 for sliding the multiple sets of pulley units 24 is mounted on the base plate 1. A track 112 is embedded in the base plate 1. A flip frame 25 is hinged to the side of the support leg 23 near the track 112, and a locking member 28 is provided on the other side. Multiple sets of guide wheel units 26 for sliding in the track 112 are mounted on the other end of the flip frame 25. The central axes of the guide wheel units 26 and the pulley units 24 are arranged along the same straight line. The central axes of the slide rail 121 and the track 112 are arranged along the same straight line. When the workbench 2 is in the retracted state, multiple sets of pulley units 24 slide out of the slide rail 121, and multiple sets of guide wheel units 26 slide into the track 112, and the workbench 2 is fixed to the track 112 by the locking member 28; when the workbench 2 is in the working state, multiple sets of guide wheel units 26 slide out of the track 112, and multiple sets of pulley units 24 slide into the slide rail 121, and the workbench 2 is fixed to the slide rail 121 by the locking member 28.

[0031] In this operating device, base plate 1 provides fixed support for worktable 2, slide rail 121, and track 112, ensuring the relative stability of each component. The support frame 22 of worktable 2 forms its main frame, used to hold professional equipment such as camera equipment and editing consoles required by the broadcast vehicle. Support legs 23 provide vertical support for the support frame 22, transferring the weight of the equipment to pulley units 24 and guide wheel units 26, protecting the equipment. Pulley units 24 provide horizontal sliding support for worktable 2 and are the main moving parts when worktable 2 is in operation. Multiple sets of pulley units 24 slide synchronously, reducing the frictional resistance between worktable 2 and slide rail 121, allowing operators to easily push worktable 2 to adjust its position and reducing physical exertion.

[0032] The slide rail 121 provides a corresponding sliding track 112 for the pulley unit 24, limiting the movement direction of the pulley unit 24 and ensuring that the worktable 2 moves only along the preset track, facilitating equipment docking and personnel operation. The smooth surface of the slide rail 121 reduces wear on the pulley unit 24 and extends the service life of the components. The alignment of the axis of the slide rail 121 and the track 112 ensures that when the worktable 2 switches states, the pulley unit 24 can smoothly slide out of the slide rail 121 and the guide wheel unit 26 can simultaneously slide into the track 112 without jamming or positional conflict, improving the smoothness of operation.

[0033] The flipping frame 25 can rotate around the hinge point to achieve precise docking between the guide wheel unit 26 and the track 112. That is, through the flipping action, the guide wheel unit 26 can automatically adjust its angle during the movement of the worktable 2 and smoothly slide into or out of the track 112 without manual disassembly or adjustment, simplifying the operation process.

[0034] The guide wheel unit 26, in conjunction with the track 112, is the main sliding and load-bearing component of the worktable 2 when it is in the folded state, and also assists the worktable 2 in completing state switching. Multiple sets of guide wheel units 26 move synchronously to ensure smooth sliding and prevent the worktable 2 from tilting. The cooperation between the guide wheel unit 26 and the tilting frame 25 allows the guide wheel unit 26 to flexibly adjust its angle to adapt to the guiding structure at the entrance of the track 112, improving the convenience of state switching. At the same time, the guide wheel unit 26 can bear the weight of the worktable 2 in the folded state and is fixed with the locking component 28 to ensure the safety of the transportation process.

[0035] The track 112 provides sliding space for the guide wheel unit 26 and is the core positioning component when the worktable 2 is in the retracted state. In the retracted state, the guide wheel unit 26 slides into the track 112 and is fixed by the locking member 28, so that the worktable 2 fits tightly against the base plate 1, significantly reducing the lateral space occupied and freeing up more space for equipment storage and personnel movement in the broadcast vehicle. The embedded structure of the track 112 avoids interference with other components and protects the guide wheel unit 26 from external collisions, ensuring the long-term reliable operation of the sliding structure.

[0036] The locking element 28 is used to fix the worktable 2 to the slide 121 or track 112 when the worktable 2 is in operation or storage state, preventing relative movement. In operation, the locking element 28 fixes the worktable 2 to the slide 121, preventing it from sliding during operation and ensuring precise equipment operation. In storage state, the locking element 28 fixes the worktable 2 within the track 112, preventing it from shaking due to bumps when the broadcast van is moving, thus protecting the equipment. The convenient operation features of the locking element 28, such as a quick-release wrench, snap-fit ​​structure, and bolt connection, make the fixing and unlocking steps during state switching simple and efficient, requiring no complex tools and improving the broadcast van's ability to quickly deploy and evacuate.

[0037] The easily foldable broadcast van platform is based on the base plate 1. The equipment is supported by the support frame 22 and support legs 23 of the workbench 2. The pulley unit 24 and the slide rail 121 work together to achieve stable support and movement in the working state. The guide wheel unit 26, the track 112 and the flipping frame 25 work together to achieve space compression in the folded state. Finally, the locking member 28 completes the fixation of the two states, thus forming a function that is stable and flexible in operation and compact and safe in folding. It solves the problem of large space occupation of the traditional broadcast van workbench 2, eliminates the need to rent additional transport vehicles to transfer some equipment, reduces operating costs, and at the same time ensures the equipment debugging time for on-site reporting.

[0038] Reference Figures 1-3 The base plate 1 has a mounting groove 111, and the track 112 is disposed in the mounting groove 111. The end of the track 112 near the slide rail 121 has a first positioning hole 1123 for connection with the locking member 28. The mounting groove 111 is a concave structure on the base plate 1 designed to accommodate the track 112, providing corresponding mounting space for the track 112 and achieving integrated installation of the track 112 and the base plate 1. The mounting groove 111 defines the position of the track 112 through physical boundaries, preventing the track 112 from shifting laterally or longitudinally during the sliding of the worktable 2. Simultaneously, the pulley unit 24, straddling both sides of the mounting groove 111, provides boundaries and avoids structural interference between components. Within the limited space of the broadcast van, the embedded design of the mounting groove 111 reduces the space occupied by the track 112.

[0039] The first positioning hole 1123 engages with the locking element 28 on the support leg 23 to achieve a rigid connection after the worktable 2 has been retracted. When the locking element 28 is connected to the first positioning hole 1123, the worktable 2 is securely fixed within the track 112. Even if the broadcast vehicle travels on bumpy roads, the worktable 2 will not shift, preventing equipment collision damage. The standardized dimensions of the positioning hole ensure that the locking element 28 can be precisely aligned every time, making operation convenient and reliable. Locking can be completed without complex tools, shortening the time spent on the retraction process. At the same time, the positional matching between the first positioning hole 1123 and the track 112 ensures the uniformity of the worktable 2 after retraction, making the layout of multiple sets of operating devices in the carriage more organized and further optimizing space utilization.

[0040] Reference Figure 2 and Figure 3The track 112 includes a base plate 1121 and baffles 1122. Baffles 1122 are installed on both sides of the base plate 1121. The base plate 1121 is installed at the bottom of the mounting groove 111. The ends of the two baffles 1122 near the slide rail 121 are V-shaped, with the V-shaped openings facing the slide rail 121. The base plate 1121 provides a flat support plane for the entire track 112 and also serves as the contact surface for the sliding of the guide wheel unit 26. Through its fixed connection with the mounting groove 111, the base plate 1121 transmits the overall force of the track 112 to the base plate 1, ensuring that the track 112 does not deform or settle when bearing the weight of the workbench 2. The baffles 1122 are vertically installed on both sides of the base plate 1121, forming a lateral constraint on the guide wheel unit 26, limiting the sliding trajectory of the guide wheel unit 26, and preventing it from shifting laterally or derailing due to external interference (such as the bumps of the broadcast vehicle) during sliding.

[0041] The V-shaped opening serves as a transitional guide structure for the workbench 2 when switching from the working state to the storage state. Its opening faces the slide rail 121, forming a gradually narrowing guide channel. When the guide wheel unit 26 slides from the slide rail 121 towards the track 112, the V-shaped opening automatically corrects the position of the guide wheel unit 26 through inclined contact. This allows the guide wheel unit 26, which might have slightly deviated, to smoothly slide into the grooved space between the baffles 1122. This reduces the precision requirements for the operator pushing the workbench 2. Even if there is a slight deviation in the pushing direction, the guide wheel unit 26 can automatically adjust to the correct trajectory under the guidance of the inclined surface, making the state switching operation more effortless and efficient, shortening the storage operation time, and adapting to the needs of rapid operation of broadcast vehicles.

[0042] Reference Figure 2 and Figure 4 A support plate 231 is installed at the bottom of the support leg 23. Multiple sets of pulley units 24 are arranged on the support plate 231. The width of the pulley units 24 is adapted to the internal width of the slide rail 121. The pulley units 24 can straddle both sides of the track 112 and slide along both sides of the mounting groove 111. A mounting seat 232 is installed on the side of the support plate 231 near the track 112 and above the support plate 231. One end of the tilting frame 25 is rotatably mounted on the mounting seat 232, and multiple sets of guide wheel units 26 are arranged on the other end. The support plate 231 is an intermediate carrier connecting the support leg 23 with the pulley units 24 and guide wheel units 26, distributing the weight of the workbench 2 borne by the support leg 23 to the pulley units 24 and guide wheel units 26. The planar structure of the support plate 231 provides a unified installation benchmark for the multiple sets of pulley units 24, ensuring that the pulley units 24 are arranged neatly, and at the same time provides a stable installation platform for the mounting seat 232, realizing a reliable connection between the tilting frame 25 and the support leg 23.

[0043] The width of the pulley unit 24 is adapted to the internal width of the slide rail 121, ensuring that both sides are in contact with the inner wall of the slide rail 121 during sliding, limiting lateral displacement and ensuring the stability of the worktable 2 in the working state; the characteristic that it can be installed across both sides of the track 112 and slide along both sides of the mounting groove 111 allows the worktable 2 to smoothly transition during state switching and avoid structural interference with the track 112.

[0044] Mounting base 232 provides a pivot point for the tilting frame 25, enabling the tilting frame 25 to achieve stable hinge around it. The firm connection between mounting base 232 and support plate 231 ensures that the tilting frame 25 does not loosen or shift when driving the guide wheel unit 26, while limiting the rotation trajectory of the tilting frame 25 to ensure that the guide wheel unit 26 can accurately align with the track 112 and smoothly disengage from the track 112 in the working state. The tilting frame 25 is L-shaped, and the L-shaped bending structure adapts to the positional relationship between the guide wheel unit 26 and the track 112, allowing the guide wheel unit 26 to fall vertically into the track 112 in the retracted state and to tilt upwards to disengage from the track 112 in the working state. The L-shaped design changes the direction of force transmission, making the tilting action less strenuous, while providing sufficient installation space for the guide wheel unit 26 and avoiding interference with the support plate 231 or pulley unit 24.

[0045] A flipping frame 25 is rotatably mounted on one end of the support plate 231, and an extension plate 27 is installed at the bottom of the other end. A locking member 28 is mounted on the extension plate 27. The extension plate 27 serves as the mounting carrier for the locking member 28, extending the distance between the locking member 28 and the support leg 23. This ensures that the position of the locking member 28 precisely corresponds to the first positioning hole 1123 of the track 112 and the second positioning hole 122 of the slide 121. This ensures that when the workbench 2 is in operation or storage state, the locking member 28 can form an effective connection with the corresponding positioning hole, restricting the movement of the workbench 2.

[0046] The end of the slide 121 furthest from the track 112 is provided with a second positioning hole 122 for connection with the locking member 28. The second positioning hole 122 is the main positioning structure that cooperates with the locking member 28 when the worktable 2 is in operation. Through the second positioning hole 122, a mechanical connection is formed with the locking member 28 on the extension plate 27, fixing the worktable 2 in the working position at the end of the slide 121. When the operator places equipment on the tabletop 21 or performs operations, the worktable 2 will not slip or shake, ensuring operational safety. The setting of the second positioning hole 122 ensures that the worktable 2 can stop at the preset position during each operation, realizing quick docking of the equipment with peripheral devices and reducing the time spent on repeated adjustments.

[0047] The second positioning hole 122 and the first positioning hole 1123 correspond to the two working modes of the workbench 2—operation state and storage state—and together constitute a complete positioning system. By cooperating with the same locking member 28, the workbench 2 can be reliably fixed in different states. The second positioning hole 122 and the first positioning hole 1123 are distributed along the axis of the base plate 1 and are consistent with the extension direction of the slide 121 and the track 112. This ensures that when the workbench 2 changes state, the locking member 28 can move with the workbench 2 and sequentially engage with different positioning holes. This meets the needs of unfolding during operation and storing when not in use in the broadcast vehicle scenario, reduces operation steps, lowers the risk of misoperation, and improves the simplicity and reliability of the overall structure.

[0048] Reference Figure 4 The workbench 2 also includes a desktop 21, which is hinged to one side of the support frame 22. A connector 221 for fixing the desktop 21 is provided on one side of the support frame 22. The connector 221 can be a snap-fit ​​connector or fixed with bolts. The desktop 21 serves as the operating surface of the workbench 2. Hinged to one side of the support frame 22, it can rotate around the hinge axis. When not in use, it can rotate so that the desktop 21 is perpendicular to the support frame 22 for storage, significantly reducing the longitudinal space occupied by the workbench 2. This facilitates compact storage within the broadcast vehicle, provides a flat surface for equipment placement and operation when unfolded, and allows for easy operation and state switching without disassembly, ensuring sufficient equipment debugging time for on-site reporting.

[0049] The connector 221 is used to secure the desktop 21 in its unfolded or folded state. It restricts the flipping of the desktop 21 through a snap-fit ​​or bolt connection, ensuring the desktop 21 remains stable and preventing the equipment from falling due to accidental flipping. The snap-fit ​​connector 221 allows for quick locking and unlocking, while the bolt connection provides higher fixing strength. Both forms are suitable for the needs of different operating scenarios.

[0050] Reference Figure 1 The substrate 1 includes a fixed plate 11 and a folding plate 12. The fixed plate 11 is connected to the folding plate 12 by multiple sets of hinges. A track 112 is set on the fixed plate 11, and a slide 121 is installed on the folding plate 12. The fixed plate 11 serves as the mounting carrier for the track 112, providing stable support for the workbench 2 in its retracted state. The folding plate 12 serves as the mounting carrier for the slide 121 and can be folded around the hinges to achieve the extension and retraction of the substrate 1's length. Multiple sets of hinges connect the fixed plate 11 and the folding plate 12, providing a folding fulcrum for the folding plate 12, enabling relative rotation between the two, and simultaneously transmitting force, so that the substrate 1 in its unfolded state forms an integral load-bearing structure. The distribution of the hinges ensures that the folding plate 12 is subjected to balanced force when folded, avoiding unilateral tilting.

[0051] Track 112 is mounted on fixed plate 11, and slide 121 is mounted on folding plate 12. Both maintain axial alignment or separation as the base plate 1 unfolds and folds. When unfolded, track 112 and slide 121 form a continuous straight line, allowing the workbench 2 to switch between working and folding states. Folding plate 12 provides a sliding support surface for the workbench 2 in working state, ensuring smooth switching. When folded, slide 121 retracts with folding plate 12, separating from track 112. Folding plate 12 fits snugly against workbench 2, reducing the overall space occupied by base plate 1 and adapting to the narrow space of the broadcast van. The lightweight design of folding plate 12 reduces the physical effort required for folding operations, allowing a single person to complete both unfolding and folding, improving operational convenience.

[0052] Example 2 This application also provides a broadcast van, including a foldable broadcast van platform and a floor. The base plate 1 of the foldable broadcast van platform is installed on the floor. The foldable broadcast van platform, through the coordinated work of the base plate 1, the worktable 2, the sliding mechanism, and the folding structure, provides a flexible operating platform for the broadcast van. It can be unfolded into a stable equipment support surface during operation to meet the professional operation needs of camera, editing, and control. When not in use, it can be retracted and stored by sliding and folding to reduce space occupation and reserve more equipment storage and personnel activity area for the broadcast van, making the layout of the van more reasonable.

[0053] The floor is the basic load-bearing structure of the broadcast vehicle, providing an installation benchmark for the easy-to-store operating equipment. The equipment is integrated with the vehicle body through the fixed base plate 1, ensuring that the equipment does not shift when the vehicle is moving or operating, thus protecting the equipment safety. Its flat surface provides an unobstructed environment for the sliding and folding movements of the equipment, ensuring smooth state switching.

[0054] Specifically, base plate 1 is installed on the floor, forming a connecting bridge between the operating device and the vehicle body. It is rigidly fixed by bolts and other connectors 221, ensuring that the sliding trajectory and folding direction of the device are compatible with the vehicle space. The operating device can quickly switch between operating and storage states. Combined with the mobility of the broadcast vehicle, the deployment and withdrawal time of the equipment is greatly shortened, enabling rapid response to the broadcasting needs of breaking news, outdoor events, and other scenarios, thereby improving the timeliness of news and the efficiency of event reporting.

[0055] The implementation process of an easily foldable broadcast van platform according to an embodiment of this application is as follows: During transport by the broadcast vehicle: The operator pushes the workbench 2 towards the track 112, simultaneously flipping the L-shaped tilting frame 25 downwards so that the guide wheel unit 26 gradually approaches the track 112; the workbench 2 is continued to be pushed, the pulley unit 24 slides out of the slide rail 121, and the guide wheel unit 26 slides into the interior of the track 112 along the V-shaped opening of the track 112 until the workbench 2 is in contact with the fixing plate 11; finally, the locking piece 28 on the extension plate 27 is aligned with the first positioning hole 1123 of the track 112 and locked, completing the storage of the workbench 2. At this time, the tabletop 21 can be folded and fixed to further compress the space. Then, the folding plate 12 is folded around the hinge to fit the workbench 2, reducing the overall length of the base plate 1 and avoiding taking up too much space in the vehicle. During on-site operation: The operator folds the folding plate 12 outward around the hinge until it is flush with the fixed plate 11, forming a complete base plate 1 support surface; at this time, the slide 121 unfolds with the folding plate 12 and automatically aligns with the axis of the track 112, providing a continuous guide trajectory for the sliding of the worktable 2.

[0056] Next, unlock the locking piece 28 on the extension plate 27, push the worktable 2 to move towards the slide 121, the guide wheel unit 26 slides out along the track 112, and simultaneously flips the L-shaped flip frame 25 upward, so that the pulley unit 24 gradually approaches the slide 121; continue to push the worktable 2, the pulley unit 24 slides along the slide 121 until it reaches the end of the slide 121 away from the track 112; align the locking piece 28 with the second positioning hole 122 of the slide 121 and lock it, thus completing the fixation of the worktable 2 in the working state.

[0057] Fold the desktop 21 on one side of the support frame 22 around the hinge axis and fix the desktop 21 with the buckle or bolt connector 221; place the camera equipment, editing console and other broadcasting equipment on the desktop 21, and ensure that the equipment is in close and stable contact with the desktop 21, and the broadcasting operation can begin.

[0058] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
