Description

Technical Field

[0001] This invention relates to the field of emergency service vehicle technology, specifically to a grassroots emergency service support vehicle that integrates patrol and duty, material transportation, on-site support and personnel transfer functions. Background Technology

[0002] Pickup trucks are commonly used as daily service vehicles in grassroots villages and mini fire stations for patrols, supply transport, and basic rescue operations. However, existing modified pickup trucks have the following technical drawbacks:

[0003] First, the cargo box space is not used properly. Heavy equipment such as generators and water pumps are usually placed at the bottom of the cargo box. When they need to be retrieved, they have to climb over the upper equipment, which is laborious and time-consuming and does not conform to the principles of ergonomics.

[0004] Secondly, the equipment is stored in a chaotic manner, lacking classification management and status visualization. Different types of equipment are mixed together and piled up, requiring people to "rummage through boxes and cabinets" to find equipment in emergencies, which seriously delays rescue opportunities.

[0005] Third, it lacks basic on-site support capabilities, and does not have support functions such as lighting, power supply, drinking water, and rest, making it difficult to meet the needs of long-term field operations.

[0006] Fourth, they are limited in function. Most existing pickup trucks are designed for fixed functions and cannot quickly switch between duty patrols, material transportation, and personnel transfer. Grassroots units need to configure multiple special vehicles, resulting in a waste of resources.

[0007] While existing technologies include modular storage designs, they mostly employ fixed partition structures, making it impossible to flexibly adjust the spatial layout according to mission requirements. Furthermore, they fail to address core issues such as low-level access to heavy equipment and visualization of equipment status. Summary of the Invention

[0008] In order to overcome the defects in the existing technology, the present invention aims to provide a modular and multifunctional grassroots emergency service support vehicle, which solves the technical problems of unreasonable space utilization, inconvenient equipment access, and lack of on-site support capabilities of existing pickup truck conversion vehicles, and achieves the goals of low-level pull-out access for heavy equipment, classified and visualized storage of medium-sized equipment, and rapid conversion of cargo box functions.

[0009] To achieve the above-mentioned objectives of the present invention, the present invention provides the following technical solution:

[0010] A modular, multi-functional emergency response vehicle for grassroots operations includes a pickup truck chassis and a cargo box mounted on the chassis. The cargo box has a three-tiered structure, comprising a bottom-level heavy equipment compartment, a middle-level modular equipment compartment, and an upper-level roof functional compartment.

[0011] The bottom heavy equipment compartment is located below the cargo box floor and includes at least two pull-out equipment trays, which are slidably mounted to the cargo box floor via heavy-duty rails. Each pull-out equipment tray is equipped with an equipment securing mechanism and a hydraulic damping buffer. The equipment securing mechanism is used to securely fix heavy equipment such as generators, water pumps, and hydraulic power stations to the trays to prevent displacement during travel. The hydraulic damping buffer provides cushioning force when the trays are pulled out and pushed back, avoiding impact.

[0012] The mid-level modular equipment compartment is located in the middle of the cargo box and includes a longitudinally extending sliding rail system and multiple equipment boxes detachably mounted on the sliding rail system. The sliding rail system includes at least two parallel guide rails fixed to the cargo box floor, and guide wheels or sliders located at the bottom of the equipment boxes that cooperate with the guide rails. The equipment boxes can slide longitudinally along the guide rails and be retrieved after sliding to the rear door of the cargo box, without needing to search for equipment in the upper level.

[0013] The upper roof compartment is located on top of the cargo box and includes a retractable lighting mast, a quickly deployable sunshade, and photovoltaic panels integrated into the sunshade. When the lighting mast is raised, it can provide large-area on-site lighting; when the sunshade is deployed, it can form a temporary work area; and the photovoltaic panels generate solar power while providing shade.

[0014] The multi-functional tailgate is hinged to the rear of the cargo box and has two modes: a fold-down worktable mode and a side-opening retrieval mode. The multi-functional tailgate includes a door panel body, a hinge assembly, and a switching locking mechanism for switching the door panel's opening state. In the fold-down worktable mode, the door panel body flips downwards to form a horizontal work surface, facilitating on-site operations; in the side-opening retrieval mode, the door panel body opens sideways, facilitating access to equipment inside the cargo box.

[0015] Furthermore, the pull-out equipment pallet of the bottom heavy equipment compartment has a first position where it is completely retracted under the cargo box floor and a second position where it is completely extended to the rear of the cargo box. The equipment pallet is equipped with a handle at the front end and a limiting block at the rear end that cooperates with the cargo box floor. The travel of the heavy-duty slide rail is not less than 80% of the equipment pallet length, ensuring that heavy equipment can be completely extended outside the cargo box for easy hoisting and maintenance.

[0016] Furthermore, the equipment boxes in the mid-level modular equipment compartment include demolition tool boxes, first aid equipment boxes, warning equipment boxes, and communication equipment boxes. Each equipment box has a transparent window on its front side, made of high-transparency polycarbonate material, facilitating quick observation of the type and quantity of equipment inside. Each equipment box has a status indicator light along its upper edge, including red and green LEDs, used to indicate the completeness of the equipment inside. Green indicates that the equipment is complete, and red indicates that equipment is missing.

[0017] Furthermore, the equipment box is equipped with an equipment presence detection device, which includes a microswitch located at the bottom of the equipment placement slot and a data acquisition module electrically connected to the control unit. When equipment is placed in the placement slot, the microswitch is triggered, generating a presence signal; when equipment is removed, the microswitch resets, generating a missing signal. The control unit generates a completeness status for each equipment box based on the state of each microswitch and controls the status indicator lights to display the corresponding colors.

[0018] Furthermore, the sliding guide rail system also includes multiple positioning grooves disposed on the side of the guide rail, and elastic positioning beads disposed on the bottom of the equipment box that cooperate with the positioning grooves. When the equipment box slides along the guide rail to the position of the positioning groove, the elastic positioning beads automatically engage with the positioning groove, thereby temporarily positioning the equipment box and preventing it from sliding while the vehicle is in motion.

[0019] Furthermore, the switching and locking mechanism of the multi-functional tailgate includes:

[0020] A vertical pivot is set on one side of the rear of the cargo box, and the door panel body is hinged to the cargo box through the vertical pivot to realize the side opening function;

[0021] A horizontal pivot assembly is provided between the lower edge of the door panel body and the bottom plate of the cargo box. The horizontal pivot assembly includes a bushing provided at the lower edge of the door panel body, an insert shaft provided on the bottom plate of the cargo box that cooperates with the bushing, and an electromagnetic drive component for driving the insert shaft to extend and retract.

[0022] When the electromagnetic drive unit drives the insertion shaft to extend and insert into the bushing, the door panel body can rotate downward around the horizontal pivot to form a downward-folding worktable state; when the insertion shaft retracts and disengages from the bushing, the door panel body can open laterally around the vertical pivot to form a side-opening retrieval state.

[0023] Furthermore, the inner side of the door panel integrates multiple functional modules, including a power socket, a USB charging port, a water dispenser outlet, and a first-aid kit mounting bracket. When the workbench is folded down, the inner side of the door panel faces upwards, forming a field work platform integrating power supply, charging, and water dispensing functions. The outer side of the door panel is equipped with reflective warning strips and LED warning light strips for nighttime warning purposes.

[0024] Furthermore, the retractable lighting mast of the upper roof functional compartment includes a mast base fixed to the roof, a retractable mast body, and an LED lighting assembly installed at the top of the mast. The mast body adopts a multi-section sleeve structure and is driven to rise and fall by an electric push rod, with a lifting height of over 3 meters. The LED lighting assembly can rotate 360° and is controlled by a remote control or control panel to achieve all-around lighting.

[0025] Furthermore, the rapidly deployable sunshade includes a roll housed on one side of the vehicle roof, a sunshade fabric that can be rolled up inside the roll, and retractable support legs. The sunshade fabric is made of waterproof and sun-resistant Oxford cloth, and its outer surface integrates a flexible photovoltaic panel, which is electrically connected to the vehicle's energy storage battery. After being deployed, the sunshade can cover the side area of ​​the cargo box, forming a sunshade working space of approximately 6-8 square meters, while the flexible photovoltaic panel generates solar power.

[0026] Furthermore, the cargo box is also equipped with an on-board microgrid system, including:

[0027] The energy storage battery pack, which uses lithium iron phosphate batteries, is located in the bottom heavy equipment compartment.

[0028] A photovoltaic controller, electrically connected to flexible photovoltaic panels and energy storage battery packs, is used to control photovoltaic charging;

[0029] The bidirectional inverter is electrically connected to the energy storage battery pack and can output 220V AC and 12V DC.

[0030] The energy management unit is electrically connected to the energy storage battery pack, photovoltaic controller, and bidirectional inverter to monitor the power status and control charging and discharging.

[0031] The vehicle-mounted microgrid system can provide 5kW of emergency power to support long-term operation of on-site lighting, power tools, and medical equipment.

[0032] Furthermore, the sliding rail system of the mid-level modular equipment compartment can be completely disassembled, creating a flat personnel transfer area at the bottom of the cargo box after disassembly. The side walls of the cargo box are equipped with foldable seats and stretcher securing devices. When it is necessary to transfer wounded personnel, the sliding rail system can be disassembled, the foldable seats can be laid flat, and the stretcher can be secured, thus enabling personnel transfer.

[0033] The beneficial effects of this invention are:

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] Three-layer partitioning for scientific storage: Through the three-layer partitioning design of the bottom heavy equipment compartment, the middle modular equipment compartment, and the upper roof functional compartment, heavy equipment can be pulled out and accessed from a low position, medium equipment can be classified and stored in a visual manner, and roof functions can be integrated, improving space utilization by more than 40%.

[0036] Quick access via sliding rails, no need to rummage: The middle equipment box adopts a sliding rail design, which can be quickly slid along the rail to the rear door position. With the help of a transparent window and status indicator lights, the equipment can be quickly located and retrieved, reducing retrieval time by 60% in emergency situations.

[0037] Dual-purpose tailgate with integrated functions: The multi-functional tailgate can switch between a fold-down work platform state and a side-opening retrieval state. When folded down, it forms an on-site work platform integrating power supply, charging, and drinking water. When opened to the side, it facilitates access to first aid equipment mounted on the inside of the tailgate panel, making it a multi-purpose device.

[0038] Self-sufficient energy, on-site support: The vehicle-mounted microgrid system, which integrates photovoltaic power generation, energy storage batteries, and inverter output, can provide 5kW of emergency power to support long-term operation of on-site lighting, power tools, and medical equipment, eliminating dependence on external power sources.

[0039] Quick conversion, multi-functional: The middle guide rail system can be completely disassembled, and the cargo box can be quickly converted into a personnel transfer area, realizing the rapid switching of four functions: duty patrol, material transportation, on-site support, and personnel transfer, meeting the diverse duty needs of the grassroots.

[0040] Intelligent management, clear at a glance: The equipment in-situ detection device monitors the status of each piece of equipment in real time, and presents it visually through status indicator lights and vehicle-mounted displays, completely solving the grassroots pain point of "having to rummage through boxes to see what's in them".

[0041] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0042] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0043] Figure 1 This is a system logic structure block diagram of the vehicle of the present invention, showing the major functional modules included in the vehicle and its hierarchical retrieval system. Detailed Implementation

[0044] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings.

[0045] like Figure 1 As shown, the present invention provides a modular and multifunctional grassroots emergency service support vehicle, the whole vehicle structure consists of two main parts: a pickup truck chassis and a cargo box set on the pickup truck chassis.

[0046] The cargo box adopts a three-layer partitioned structure, including a bottom heavy equipment compartment, a middle modular equipment compartment, and an upper roof functional compartment, which together form a layered quick access system.

[0047] In addition, the vehicle also integrates a multi-functional tailgate, an on-board microgrid system, and an equipment in-situ detection system. These systems work together to achieve efficient service support.

[0048] The structure and functions of each level are described in detail below:

[0049] I. Bottom Floor Heavy Equipment Cabin

[0050] The lower-level heavy equipment compartment is located below the cargo box floor, making full use of the space between the cargo box floor and the chassis. This compartment includes at least two pull-out equipment pallets, each of which is slidably mounted to the cargo box floor via heavy-duty rails.

[0051] The pull-out equipment pallet has a first position where it is completely retracted under the cargo box floor, and a second position where it is completely extended to the rear of the cargo box. A handle is located at the front of the pallet for easy pulling out; a stop block that engages with the cargo box floor at the rear prevents the pallet from being excessively extended and derailing. The heavy-duty slide rails use high-strength ball bearing rails with a load-bearing capacity of no less than 200kg and a travel of no less than 80% of the equipment pallet length, ensuring that heavy equipment can be completely pulled out of the cargo box.

[0052] The equipment tray is equipped with a securing mechanism, including strap fixing points and dedicated slots, for firmly securing heavy equipment such as generators, water pumps, and hydraulic power stations. A hydraulic damping buffer is installed between the equipment tray and the slide rails to provide uniform damping force when the tray is pulled out and pushed back, preventing impact and noise.

[0053] II. Mid-level Modular Equipment Cabin

[0054] The mid-level modular equipment compartment, located in the middle of the cargo container, is the core area for equipment storage. This compartment includes a longitudinally extending sliding rail system and multiple equipment containers that can be detachably mounted on the sliding rail system.

[0055] The sliding guide rail system includes at least two parallel guide rails fixed to the cargo box floor, extending longitudinally along the cargo box. Guide wheels or sliders that mate with the guide rails are provided on the bottom of the equipment box, allowing the equipment box to slide freely along the guide rails. Multiple positioning grooves are provided on the sides of the guide rails, and elastic positioning beads that mate with the positioning grooves are provided on the bottom of the equipment box. When the equipment box slides along the guide rail to the positioning groove, the elastic positioning beads automatically engage with the positioning groove, achieving temporary positioning of the equipment box and preventing it from sliding while the vehicle is in motion.

[0056] The equipment cases include various types such as demolition tool cases, first aid equipment cases, security equipment cases, and communication equipment cases, which can be flexibly configured according to mission requirements. Each equipment case has a transparent window on the front side, made of high-transmittance polycarbonate material, for easy and quick observation of the type and quantity of equipment inside.

[0061] The quick-deployment sunshade includes a roll stored on one side of the vehicle roof, a retractable sunshade fabric inside the roll, and extendable support legs. The sunshade fabric is made of waterproof and sun-resistant Oxford cloth and, when unfolded, covers the side area of ​​the cargo box, creating approximately 6-8 square meters of shaded working space. The outer surface of the sunshade fabric integrates flexible photovoltaic panels, using lightweight, flexible solar cell encapsulation, electrically connected to the vehicle's energy storage battery, generating solar power while providing shade.

[0062] IV. Multifunctional tailgate

[0063] The multi-functional tailgate is hinged to the rear of the cargo box and can be configured as a fold-down work platform or a side-opening retrieval mode.

[0064] The multi-functional tailgate includes a door panel body, a hinge assembly, and a switching locking mechanism for switching the door panel's open state. The switching locking mechanism includes a vertical pivot located on one side of the rear of the cargo box, and a horizontal pivot assembly located between the lower edge of the door panel body and the cargo box floor.

[0065] The vertical pivot allows the door panel to be laterally hinged to the cargo box. When the horizontal pivot assembly is disengaged, the door panel can be opened laterally around the vertical pivot, forming a side-opening access state, which facilitates the retrieval of equipment inside the cargo box.

[0066] The horizontal pivot assembly includes a bushing located along the lower edge of the door panel body, an insert shaft located on the cargo box floor plate and engaging with the bushing, and an electromagnetic drive unit for driving the insert shaft to extend and retract.
