Description

Technical Field

[0001] This utility model relates to the field of broadcast vans, and in particular to a broadcast van connecting corridor structure. Background Technology

[0002] Broadcast vans, especially large ones used for live programming at major events or activities, integrate a large amount of expensive audio-visual equipment and workstations into their interior space. In practical applications, to meet complex production needs, it is often necessary to park two or more broadcast vans side by side to form a larger production system. This necessitates the establishment of a connecting corridor between the vehicles to allow for the safe and smooth passage of equipment and personnel.

[0003] Existing vehicle walkway systems mostly employ simple canopy structures or single telescopic platforms, which have several limitations: First, the telescopic stroke is limited, making it difficult to adapt to varying distances between different vehicle models; second, they lack stable support, causing the walkway to sway easily, and the canopy to sag and accumulate rain and snow, posing safety hazards; third, their sealing is poor, failing to effectively isolate wind, rain, and dust, impacting the working environment of precision equipment and personnel; fourth, their automation level is low, with deployment and take-down processes being cumbersome, time-consuming, and inefficient. Therefore, there is an urgent need for a new type of broadcast vehicle walkway structure that can overcome these shortcomings. Utility Model Content

[0004] The purpose of this utility model is to provide a connecting corridor structure for broadcast vehicles, so as to improve the convenience of joint operations of broadcast vehicles and the space utilization rate.

[0005] This utility model is achieved using the following technical solution: a broadcast vehicle corridor structure, characterized in that it includes a primary telescopic mechanism, comprising a fixed component fixedly installed at the bottom of the vehicle body and a sliding component slidably connected to the fixed component via a linear guide pair; a secondary telescopic mechanism, nested on the sliding component of the primary telescopic mechanism, and capable of extending or retracting relative to the sliding component; a corridor platform, fixedly installed on the secondary telescopic mechanism, serving as a walking platform for the corridor; a tarpaulin, connected between the sliding component of the primary telescopic mechanism and the corridor platform; and a tarpaulin telescopic structure, disposed inside the tarpaulin, for supporting the unfolding of the tarpaulin when the corridor platform extends, and folding to retract the tarpaulin when the corridor platform retracts.

[0006] Furthermore, a rigid canopy is fixedly installed on the sliding component of the primary telescopic mechanism.

[0007] Furthermore, one end of the tarpaulin is fixed to the edge of the rigid roof, and the other end is fixed to the end of the walkway platform.

[0008] Furthermore, the tarpaulin telescopic structure is a scissor-type frame structure.

[0009] Furthermore, the secondary telescopic mechanism achieves telescopic movement through a drive assembly and multiple electric push rods; the drive assembly is hinged to the sliding assembly of the primary telescopic mechanism; the cylinder end of each electric push rod is hinged to the drive assembly, and the push rod end is connected to the bottom of the corridor platform.

[0010] Furthermore, the drive assembly includes a servo motor and a reducer.

[0011] Furthermore, a docking frame is provided at the end of the corridor platform, and a sealing structure and a locking mechanism are provided on the docking frame.

[0012] Furthermore, the tarpaulin is a multi-layered composite waterproof canvas material.

[0013] The beneficial effects of the broadcast vehicle corridor structure described in this utility model include: Through the nested design of primary and secondary telescopic mechanisms, a larger connection span is achieved within the limited vehicle space, which can flexibly adapt to various spacing requirements between different broadcast vehicles.

[0014] The primary mechanism uses high-load linear guide pairs, while the secondary mechanism uses multiple sets of high-thrust electric push rods synchronously controlled by a servo drive system. This ensures the smooth, synchronous, and precise extension and retraction of the entire corridor platform, resulting in strong load-bearing capacity and safe and reliable operation.

[0015] The system employs a composite design combining a rigid roof and a flexible tarpaulin. The rigid roof serves as the main load-bearing and sheltering structure, ensuring the rigidity of the main structure. The scissor-type frame integrated inside the tarpaulin can automatically expand, providing stable support for the tarpaulin and forming a reliable retractable weatherproof passage, effectively protecting the internal equipment and personnel.

[0016] The entire process of unfolding and retracting the connecting corridor can be operated with a single button via the electronic control system. The high degree of automation greatly reduces the time and intensity of manual operation, and improves work efficiency and response speed for joint operations.

[0017] The rigid docking frame at the end of the corridor platform is equipped with sealing strips and locking mechanisms, which can achieve a firm and sealed docking with the target broadcast vehicle, ensuring the integrity and stability of the corridor. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0022] This embodiment provides a corridor structure for broadcast vans, designed to safely and efficiently expand the workspace of broadcast vans and facilitate smooth flow of equipment and personnel. For example... Figure 1-3 As shown, the structure mainly includes a primary telescopic mechanism 1 and a secondary telescopic mechanism 3.

[0023] The primary telescopic mechanism 1, serving as the main load-bearing and driving foundation, includes a fixed assembly bolted to the bottom of the carriage and a sliding assembly slidably connected thereto via a high-load linear guide pair. A lightweight, high-strength rigid aluminum alloy canopy is fixedly mounted on the sliding assembly, which moves as a whole with the sliding assembly, forming the main shelter structure of the connecting corridor.

[0024] The secondary telescopic mechanism 3 is nested on the sliding component of the primary telescopic mechanism 1 and can be slidably connected to it via another set of guide rails to achieve secondary extension, thereby significantly increasing the telescopic stroke of the connecting corridor. The supporting body of the secondary telescopic mechanism 3 is the corridor platform 5, on which multiple high-thrust electric push rods 4 are symmetrically arranged on both sides of the bottom. The cylinder end of each electric push rod 4 is connected to the drive assembly 2 through a universal joint hinge seat, while its push rod end is firmly connected to the bottom frame of the corridor platform 5 through the electric push rod fixing structure 6. The drive assembly 2 is preferably a combination of a servo motor and a reducer, and its housing is hinged to the sliding component of the primary telescopic mechanism through a pin to ensure effective force transmission and compensate for installation errors. During operation, the drive assembly 2 outputs torque to drive the electric push rods 4 to perform synchronous telescopic movements, thereby accurately and smoothly pushing the entire corridor platform 5 to extend or retract.

[0025] The end of the corridor platform 5 (i.e., the end furthest from the broadcast van body) is equipped with a rigid docking frame. This frame is surrounded by sealing strips and can be optionally equipped with an electromagnetic lock or mechanical locking hook mechanism for a secure and sealed docking with the corresponding interface of another broadcast van. The tarpaulin 7 is made of multi-layer composite waterproof canvas material. One end is fixed to the edge of the rigid roof via pressure strip bolts, and the other end is also fixed to the docking frame of the corridor platform 5 via pressure strips. The tarpaulin 7 integrates a tarpaulin telescopic structure 8, preferably multiple parallel scissor frames. Its innermost end (closest to the broadcast van body) is fixedly connected to the side or bottom of the rigid roof via a hinged seat; its outermost end is fixedly connected to the docking frame at the end of the corridor platform 5 in the same way. When the corridor platform 5 extends, the tarpaulin 7 is unfolded, and its internal scissor frames automatically expand, providing stable support for the tarpaulin and forming a reliable telescopic, weatherproof channel. When the platform retracts, the frames fold accordingly, neatly folding the tarpaulin.

[0026] In operation, the two broadcast vans are parked side by side. First, the sliding component of the primary telescopic mechanism 1 extends, moving the rigid canopy to its maximum travel. Then, the drive component 2 activates, pushing the electric push rod 4 to further extend the secondary telescopic mechanism 3 and its connecting platform 5 until the docking frame at its end is tightly fitted and locked into place with the docking port of the target broadcast van. During this process, the canopy 7 is automatically stretched and unfolded, supported by the internal canopy telescopic structure 8, forming a protected, enclosed passageway extending from the main vehicle to the target vehicle.

[0027] This utility model, through its two-stage telescopic mechanism design, achieves a greater connection span within a limited vehicle space, with smooth and reliable telescopic movements. The composite design of the rigid roof and the tarpaulin ensures the rigidity of the main structure while the flexible tarpaulin adapts to complex telescopic deformation requirements, ultimately forming a safe, stable, and rapidly deployable corridor passage, greatly improving the convenience and space utilization of joint operations for broadcast vehicles.

[0028] The above embodiments describe the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Modifications and variations made by those skilled in the art without departing from the spirit and scope of this utility model should be protected within the scope of the appended claims.
