Description

Technical Field

[0001] This utility model relates to the field of vehicle equipment technology, specifically to a rotating cargo pallet and vehicle. Background Technology

[0002] Currently, the conventional way to arrange equipment on fire trucks is to build fixed frame structures inside equipment boxes and then use various clamps to secure the equipment to these frames. This method has significant drawbacks: First, because the dimensions of various equipment differ, fixing multiple pieces of equipment in the same space inevitably wastes a lot of irregular, fragmented space to accommodate the largest pieces, resulting in low space utilization. Second, when equipment is stacked or tightly packed, retrieving items located at the back or bottom is extremely inconvenient, especially in time-sensitive rescue situations, potentially delaying crucial rescue efforts. Finally, classifying and managing the equipment is also difficult, making it hard to store similar items together.

[0003] In view of the above-mentioned shortcomings of the existing technology, there is an urgent need to provide a new equipment loading scheme to overcome the problems of unreasonable equipment layout, wasted space and inconvenient access in the existing technology. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a rotating cargo pallet and vehicle to solve the technical problems of unreasonable equipment layout, wasted space and inconvenient loading and unloading in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present application adopts the following technical solution:

[0006] In a first aspect, this application provides a rotating cargo tray, comprising:

[0007] Bottom rotating component to provide bottom rotation support;

[0008] A top rotating component, coaxially arranged with the bottom rotating component, is used to provide top rotational support;

[0009] The equipment mounting assembly is movably connected between the bottom rotating assembly and the top rotating assembly, and is used to support fire-fighting equipment;

[0010] A rotating control mechanism is used to control the rotation and locking of the equipment mounting assembly.

[0011] In some embodiments of this application, the equipment mounting assembly includes a rotating support frame, one side of which is provided with at least one tray box, and the other side is provided with an equipment hanging plate. The equipment hanging plate is provided with multiple hooks or clamps for hanging shovels, crowbars, or fire hammers. The tray box is used to place lightweight shears, lightweight spreaders, or toothed saws.

[0012] In some embodiments of this application, the rotating support frame is provided with a plurality of mounting holes along its height direction, and the tray box can be selectively mounted on different mounting holes via connectors to adjust the vertical spacing between the tray boxes.

[0013] In some embodiments of this application, the bottom of the tray box is provided with a plurality of drainage holes, and the inner bottom surface of the tray box is inclined toward the drainage holes. The inner wall and bottom of the tray box, as well as the area where the equipment hanging plate contacts the equipment, are lined with an elastic shock-absorbing layer and a friction anti-slip layer.

[0014] In some embodiments of this application, the rotating tray control mechanism includes a rotating handle, an internal control mechanism linked to the rotating handle, and a rotating tray locking shaft driven by the internal control mechanism; the rotating tray locking shaft is used to insert into or disengage from a locking structure disposed on the bottom rotating assembly or the top rotating assembly to lock or unlock the equipment mounting assembly.

[0015] In some embodiments of this application, a safety locking sensor and an alarm are also included; the safety locking sensor is used to detect whether the rotary tray shaft is in a locked state, and when the vehicle is started and the safety locking sensor detects that the rotary tray shaft is not locked, the alarm emits an audible and visual alarm.

[0016] In some embodiments of this application, the bottom rotating assembly includes a bottom fixed seat and a bottom rotating shaft seat disposed thereon; the top rotating assembly includes a top fixed seat and a top rotating shaft extending therefrom; the equipment mounting assembly is rotatably connected through the bottom rotating shaft seat and the top rotating shaft.

[0017] In some embodiments of this application, the bottom fixing base is provided with a ring-shaped positioning plate, and the positioning plate is provided with positioning holes corresponding to 0 degrees, 90 degrees and 180 degrees respectively; the end of the rotating tray shaft selectively engages with the positioning holes to lock the tray in the fully retracted, half-open and fully open positions.

[0018] In some embodiments of this application, a damping buffer mechanism is also included, which is connected between the equipment mounting assembly and the bottom or top mounting base to provide cushioning during the start and end phases of tray rotation.

[0019] Secondly, this application also provides a vehicle including an equipment and supplies box and a rotating cargo tray as described in any embodiment of the first aspect, the rotating cargo tray being installed inside the equipment and supplies box.

[0020] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include:

[0021] By incorporating a stable, top-and-bottom rotating support structure with bottom and top rotating components, and controlling the rotation and locking of the equipment mounting components that can support the equipment via a rotating tray operating mechanism, traditional fixed storage is transformed into dynamic, rotating access. This design allows firefighters to easily rotate the tray out, making convenient access to all surfaces of the tray, thereby quickly and accurately retrieving the necessary equipment. This significantly improves space utilization and operational convenience, effectively enhancing emergency response speed. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a rotating cargo pallet and vehicle to solve the technical problems of unreasonable equipment layout, wasted space and inconvenient loading and unloading in the prior art.

[0036] To achieve the above-mentioned technical objectives, the present application adopts the following technical solution:

[0037] Please see Figures 1 to 5 This embodiment provides a rotating cargo tray. The tray includes four core components: a bottom rotating assembly 10, a top rotating assembly 20, an equipment mounting assembly 30, and a rotating tray operating mechanism 40.

[0038] Specifically, the bottom rotating assembly 10 is mounted on the bottom plate of the equipment box to provide stable bottom rotation support for the entire pallet. The top rotating assembly 20 is mounted on the top plate of the equipment box, with its rotation center strictly aligned with the rotation center of the bottom rotating assembly 10, forming a coaxial configuration to provide top rotation support. This dual-point support structure with top and bottom axes ensures that the subsequently installed equipment mounting assembly 30 remains stable during load-bearing rotation, without wobbling or tilting.

[0039] The equipment mounting assembly 30 is movably connected between the bottom rotating assembly 10 and the top rotating assembly 20, and is the main body that carries various fire-fighting equipment. The rotating control mechanism 40 is integrated into or linked to the equipment mounting assembly 30. Firefighters can easily control the equipment mounting assembly 30 to unlock from the locked state, rotate to the required angle, and then lock it again by operating this mechanism.

[0040] When retrieving or placing equipment, firefighters first operate the rotating support mechanism 40 to release the lock on the equipment mounting assembly 30. Then, grasping the equipment mounting assembly 30 or its handle, they gently apply force to rotate it around the central axis defined by the bottom rotating assembly 10 and the top rotating assembly 20. Once the required equipment is in a position facing the operator, the firefighter releases or reverses the rotating support mechanism 40 to relock the equipment mounting assembly 30 in its current position, ensuring stability during retrieval and placement. The procedure is reversed when storing equipment. The entire process is smooth, effortless, and safe.

[0041] This embodiment utilizes the coordinated operation of four major components to construct a fully functional and structurally stable rotary equipment storage system. It fundamentally changes the way equipment is stored and retrieved, allowing equipment hidden deep inside the equipment case to be easily moved to the most accessible position via rotation. This greatly improves the space utilization of the equipment case and the convenience of equipment retrieval, saving valuable time for emergency rescue.

[0042] The structure of the equipment mounting assembly 30 is further optimized. Specifically, the equipment mounting assembly 30 includes a rotating tray frame 31 as a skeleton. The rotating tray frame 31 is available on both sides, with at least one, preferably three or more, tray boxes 32 on one side (e.g., the back), and a single or segmented equipment hanging plate 33 on the other side (e.g., the front).

[0043] The equipment hanging plate 33 is equipped with multiple hooks or clamps specifically designed for hanging long-handled or ringed equipment, such as fire shovels, crowbars, fire axes, and fire hammers. The tray box 32 is designed as an open container for storing relatively regular-shaped block-shaped equipment, especially high-value demolition equipment, such as lightweight shears, lightweight spreaders, and toothed saws.

[0044] This dual-sided, zoned design enables the scientific classification and management of equipment. Long-handled tools and demolition equipment are clearly separated and placed in their proper positions. This not only makes the entire equipment layout look orderly, but more importantly, it allows firefighters to find the target equipment at a glance according to the needs of the mission, avoiding searching through a chaotic pile of equipment and significantly improving response speed.

[0045] To further enhance the pallet's adaptability, the rotating pallet frame 31 has multiple rows of mounting holes 34, either evenly or non-evenly, along the height of its uprights. Each pallet box 32 can be selectively mounted on these different mounting holes 34 via bolts or other connecting components.

[0046] In this way, firefighters can flexibly adjust the vertical spacing between the various tray boxes 32 according to the height of the equipment (such as different models of spreaders) that need to be placed. For example, when a tall toothed saw needs to be placed, the tray box 32 above it can be moved upwards by one or more holes to leave enough space for it.

[0047] The adjustable 32mm spacing of the pallet box gives it exceptional flexibility and compatibility. It breaks away from the limitations of traditional fixed shelving with its unchanging shelf height, perfectly accommodating equipment of various heights and eliminating wasted vertical space due to differences in equipment size, thus maximizing space utilization.

[0048] The details of the tray box 32 and the equipment hanging plate 33 are optimized. First, multiple drainage holes are provided at the bottom of each tray box 32, and the inner bottom surface of the tray box 32 is designed as a slightly sloping surface towards the drainage holes. Second, a composite functional layer is provided on the inner wall and bottom of the tray box 32, as well as on the areas of the equipment hanging plate 33 where equipment may come into contact (such as the lining of hooks or clamps). This composite functional layer preferably includes an elastic shock-absorbing layer (such as EVA foam or rubber) in close contact with the substrate and a friction anti-slip layer (such as a textured rubber coating or anti-slip mat) on the surface.

[0049] The design of the drainage holes and sloping bottom allows for the timely removal of water brought in by rain or equipment washing, preventing equipment corrosion and dampness inside the case. The elastic shock-absorbing layer and friction-resistant anti-slip layer effectively cushion impacts during vehicle travel, protecting precision equipment from damage. Furthermore, they increase the friction between the equipment and the tray, preventing slippage, displacement, or collisions during rotation or travel, ensuring stable storage of the equipment.

[0050] The specific structure of the rotary support operating mechanism 40 is described below. The mechanism includes a rotary handle 41 operated by a firefighter, an internal operating mechanism (such as a linkage or gear mechanism) that converts and transmits the handle's movement, and a rotary support shaft driven by the internal operating mechanism to extend, retract, or rotate axially.

[0051] Correspondingly, a locking structure (e.g., a positioning disc with a positioning hole) is provided on the fixed part of the bottom rotating assembly 10 or the top rotating assembly 20. During operation, rotating the rotating handle 41 causes the internal operating mechanism to disengage the rotating tray shaft from the locking structure, thereby unlocking the tray. After rotating the tray to the target position, reversing the operation or releasing the handle causes the rotating tray shaft to automatically insert into the corresponding locking structure under the action of a spring or other reset element, completing the locking.

[0052] This mechanically linked control mechanism is simple in structure, reliable in operation, and durable. Firefighters can complete all operations—unlocking, rotating, and locking—with one hand. The process is intuitive and convenient, ensuring a rapid response in emergencies and guaranteeing the absolute stability of the pallet during vehicle movement.

[0053] An active safety warning function is added to this invention. This function includes a safety locking sensor and an alarm. The safety locking sensor, such as a microswitch or Hall sensor, is installed near the locking structure to detect in real time whether the rotary tray shaft is fully inserted and in a locked state.

[0054] The sensor's signal line is connected to the vehicle's electronic control system (such as ACC power or CAN bus) and the alarm. The system logic is set so that when the vehicle starts (ACC is powered on), the control unit will detect the status of the safety lock sensor. If the rotary lever shaft is detected to be in an unlocked state, the alarm will immediately sound an audible or verbal alert and display an audible and visual alarm signal on the instrument panel or central control screen in the driver's cab to remind the driver or firefighters.

[0055] The addition of active safety features effectively prevents the pallet from suddenly rotating and flying off while the vehicle is moving, turning, or experiencing bumps due to human negligence (forgetting to lock the pallet), which could cause equipment damage or even serious safety accidents. This feature greatly enhances the driving safety of fire trucks.

[0056] The locking structure is specifically designed. A separate, replaceable steel positioning plate is coaxially mounted on the bottom mounting base 11. This positioning plate has at least three positioning holes along its circumference, precisely corresponding to the tray's positions at 0 degrees (fully retracted), 90 degrees (partially unfolded, suitable for operation in confined spaces), and 180 degrees (fully unfolded, with the back of the tray facing outwards). The end shape of the rotating tray shaft matches the positioning holes (e.g., a tapered fit) to achieve selective insertion and locking.

[0057] The multi-angle precise positioning and locking design greatly enhances the pallet's adaptability on-site. Firefighters can choose the most suitable unfolding angle to retrieve and place equipment according to the width of the working space, ensuring convenience and efficiency in both open areas and narrow alleys.

[0058] The rotating support structure is described in detail. The bottom rotating assembly 10 includes a bottom mounting base 11 fixed to the floor of the carriage by bolts, and a bottom rotating shaft seat 12 mounted on the mounting base and containing a bearing inside. The top rotating assembly 20 includes a top mounting base 21 fixed to the roof of the carriage, and a top rotating shaft 22 extending vertically downward from the top mounting base 21.

[0059] The bottom of the equipment mounting assembly 30 is rotatably connected to the bottom rotating shaft seat 12, and its top is rotatably connected to the top rotating shaft 22. Through this dual-point support, the force generated by the equipment mounting assembly 30 and the weight it carries is effectively distributed to the top and bottom of the vehicle body, ensuring smooth rotation and strong load-bearing capacity.

[0060] The dual-point support structure with top and bottom hinges ensures reasonable stress distribution and strong structural rigidity, enabling it to withstand loads of tens of kilograms or even heavier equipment without deformation or shaking, thus guaranteeing the reliability and durability of the pallet during long-term use.

[0061] To improve operational comfort and safety, this invention also includes a damping mechanism. This damping mechanism is preferably a hydraulic rotary damper, with one end connected to the rotating part of the equipment mounting assembly 30 and the other end connected to the fixing part of the bottom mounting base 11 or the top mounting base 21.

[0062] When the tray is unlocked and begins to rotate, and just before it is locked, the damping mechanism provides a smooth damping force in the opposite direction of rotation, effectively controlling the tray's rotation speed and preventing sudden acceleration or impact caused by excessively fast operation or shift in the equipment's center of gravity.

[0063] The introduction of the damping and buffering mechanism makes the rotation of the pallet more stable and controllable, avoiding rigid impacts. This not only protects the structure of the pallet itself and the precision equipment it carries, but also greatly improves the firefighters' operating feel and safety, reflecting a human-centered design concept.

[0064] Furthermore, to address rescue operations at night or in low-light conditions, a high-brightness LED lighting strip can be integrated into the side or top of the rotating tray frame 31. The power supply for this strip is introduced from the mounting base via a conductive slip ring, ensuring normal illumination regardless of the tray's rotation angle. The strip can be linked to the equipment case door control switch, illuminating immediately upon opening the door and providing ample light for equipment identification and retrieval.

[0065] Furthermore, in order to reduce the overall weight, facilitate operation and reduce vehicle fuel consumption, the rotating frame 31, tray box 32 and equipment hanging plate 33 can be made of high-strength lightweight materials, such as 6061-T6 aerospace-grade aluminum alloy profiles or higher-end carbon fiber composite materials, and the surface can be anodized or sprayed with a wear-resistant coating.

[0066] Furthermore, to utilize the space deep within the equipment case, a retractable heavy-duty ball bearing slide can be installed below the bottom mounting base 11 of the entire rotating tray. This allows the entire tray unit to be fully pulled out of the equipment case before rotating the tray, making it easy to access the equipment on the back of the tray and solving the problem of dead corners inside the deep case.

[0067] Furthermore, when the pallet is heavily loaded, a gas spring assist mechanism can be installed near the axis of rotation to make operation easier. This gas spring is compressed when the pallet is in the stowed state; when unlocked, its elasticity assists in rotating the pallet outwards, significantly reducing the initial operating force required by firefighters.

[0068] Furthermore, to facilitate the storage and readiness of equipment, dedicated charging interfaces and mounting brackets can be installed within the tray box 32 for devices such as electric demolition tools. Power is also introduced through conductive slip rings to ensure that the power tools can be automatically charged during storage, maintaining optimal combat readiness at all times.

[0069] This utility model also provides a vehicle, particularly a fire truck. The vehicle includes a body and an equipment and supplies container mounted on the body. Inside the equipment and supplies container, a rotating cargo tray as described in any of the foregoing embodiments or a combination thereof is installed. The bottom mounting base 11 and top mounting base 21 of the tray are securely mounted on the bottom and top plates of the equipment and supplies container, respectively, forming an efficient and integrated vehicle-mounted equipment management system.

[0070] Vehicles equipped with the rotating cargo tray of this invention experience a qualitative leap in their onboard equipment loading capacity, space utilization, ease of access, and scientific management. This directly translates into higher work efficiency and stronger operational support capabilities at emergency rescue sites, and is of great significance for improving the overall performance of the vehicle.

[0071] This utility model's rotating cargo tray provides stable support through its pivot-type rotating assembly. After firefighters unlock it using the operating mechanism, they can easily rotate the double-sided mounting assembly carrying the equipment to a convenient operating position and lock it using a multi-point positioning mechanism. The entire system integrates multiple functions such as categorized storage, adjustable spacing, shock absorption and anti-slip, safety alarm, damping buffer, lighting, power assist, charging, and slide rail extension, forming a complete and efficient vehicle-mounted equipment management solution.

[0072] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include:

[0073] High space utilization: The three-dimensional, rotating design effectively utilizes the vertical and depth space of the equipment box, resulting in greater loading capacity.

[0074] Extremely convenient to pick up and put down: With a simple rotation, equipment in any position can be brought to your hand, greatly reducing the time required to retrieve equipment.

[0075] Scientific equipment management: The double-sided partition design facilitates equipment classification, while the adjustable trays can adapt to different sizes, making the equipment arrangement more reasonable.

[0076] Protecting equipment safety: The shock-absorbing and anti-slip layer and damping buffer mechanism effectively protect the equipment from damage caused by driving bumps and operational impacts.

[0077] Safe and reliable operation: The reliable locking mechanism and active safety alarm system ensure dual safety during driving and operation.

[0078] Excellent ergonomics: Combining features such as power assist, lighting, and convenient operation, it reduces the workload of firefighters and improves their operating experience.

[0079] Highly adaptable and expandable: Features such as multi-angle locking and slide rail extension enable it to adapt to various complex field environments, while modular interfaces also leave room for future upgrades.

[0080] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0081] The specific embodiments described above do not constitute a limitation on the scope of protection of this application.
