Description

Technical Field

[0001] This utility model relates to the field of special vehicle technology, and in particular to a kitchen vehicle. Background Technology

[0002] Mobile catering vehicles, as motorized food supply equipment, are widely used in military logistics, field operations, emergency rescue and disaster relief, and other fields.

[0003] In existing technologies, the main and side dish processing equipment in cooking vehicles typically uses fuel-fired stoves as the core power source, with diesel stoves being the mainstream configuration. This type of equipment generates an open flame by burning diesel fuel, driving cooking utensils to perform processing functions such as steaming, boiling, stir-frying, and baking. However, this technical solution has the following significant drawbacks:

[0004] Because diesel stoves rely on open flame operation, their flame stability is poor when used in strong winds or enclosed spaces, which can easily lead to problems such as fuel leakage, accidental flameout, or loss of fire control, posing a risk of fire or even explosion.

[0005] In addition, fuel-fired stoves require frequent refueling, and diesel storage and transportation necessitate strict fire and explosion prevention measures, increasing the logistical burden. Furthermore, burners are prone to carbon buildup and require regular cleaning and maintenance, limiting their practicality in harsh outdoor environments. Utility Model Content

[0006] This utility model provides a cooking vehicle to solve at least one of the above-mentioned technical defects in the prior art. Through three major technological breakthroughs—electromagnetic cooking appliances to replace open flame stoves, modular expansion of the cabin, and intelligent energy management—it systematically solves the technical defects of traditional cooking vehicles in terms of safety, energy efficiency, space utilization, and environmental adaptability.

[0016] The vehicle frame is provided with a tail plate at the rear, which is adapted to switch between a folded state and a flat state. In the folded state, the tail plate is attached to the cooking cabin; in the flat state, the tail plate serves as the take-off and landing platform for the delivery drone.

[0017] The cooking cart provided by this utility model also includes at least four leveling legs, which are located near both ends of the cart frame.

[0018] According to the cooking vehicle provided by this utility model, the processing area includes a staple food processing area and a side dish processing area arranged opposite to each other;

[0019] The countertop in the staple food processing area is equipped with an electric pressure cooker and a rice steamer.

[0020] The countertop of the food processing area is equipped with an induction cooker, a steam oven, and a condiment cabinet.

[0021] Both the staple food processing area and the non-staple food processing area are equipped with exhaust hoods.

[0022] According to the cooking cart provided by this utility model, the preparation area has a first side and a second side arranged opposite to each other;

[0026] According to the cooking vehicle provided by this utility model, the water supply module includes a pressurized water pump and a water storage tank, a water purifier, a clean water tank, a water heater, and a hot water tank connected in sequence.

[0027] The booster pump is installed on the pipes of the water storage tank, the water purifier, the purified water tank, the water heater, and the hot water tank;

[0028] The power supply module includes a PLC control box, and the power input terminal of the PLC control box is connected to the output terminal of the AC power distribution cabinet.

[0029] According to the cooking cart provided by this utility model, the storage area is equipped with a refrigerator and a disinfection cabinet;

[0034] The inverter integrates the power battery, engine generator, and external power grid input, implementing a priority power supply strategy (such as battery priority and emergency power replenishment) through an AC distribution cabinet to ensure continuous operation during power outages or extreme environments. The inverter and AC distribution cabinet monitor the electrical load of processing and storage areas in real time, dynamically adjusting power distribution (such as automatically increasing power supply during peak cooking periods) to avoid energy waste and extend battery life. Processing equipment (such as induction cookers and electric steamers) is centrally controlled through a high-voltage distribution box, supporting preset cooking programs and precise temperature adjustment, reducing manual intervention and operational errors, and improving work efficiency. The power system eliminates the need for complex maintenance such as fuel filtration and burner cleaning. The power battery and inverter adopt a modular design, supporting rapid replacement or upgrades, reducing field maintenance time by more than 60%. The sealed design of the inverter and power battery within the compartment ensures stable power supply in harsh environments such as rain and sandstorms. Combined with the rapid deployment function of the expansion compartment, it achieves rapid response in all weather and terrain conditions.

[0035] The kitchen vehicle provided in this embodiment of the utility model achieves three major technological breakthroughs: replacing open flame stoves with hybrid power, modular expansion cabin, and intelligent energy management.

Figure 2 This is a right view of the cooking cart provided in this embodiment of the utility model. Figure 3This is a rear view of the cooking cart provided in this embodiment of the utility model. Figure 4 This is a schematic diagram of the connection of the chassis assembly in the cooking vehicle provided in this embodiment of the utility model. Figure 5 This is a wiring diagram of the upper structure components of the cooking vehicle provided in this embodiment of the utility model.

[0052] See Figures 1 to 5 This utility model provides a kitchen vehicle, which includes a chassis assembly 400 and a kitchen container.

[0053] The chassis assembly 400 includes a chassis body 410 and an engine 420, a hybrid transmission 430, and a power battery 440 mounted on the chassis body 410. The engine 420 and the hybrid transmission 430 are connected via a transmission assembly, such as a belt drive or a chain drive. Belt drive, for example, offers advantages in terms of simple structure and low cost, reducing production costs in catering vehicles. The hybrid transmission 430 is rigidly connected to the drive shaft 450, ensuring efficient power transmission to the wheels and enabling the catering vehicle to operate under various road conditions, such as navigating rough terrain to reach locations requiring catering services. The power battery 440 is electrically connected to a motor controller and a high-voltage distribution box via high-voltage cables. The motor controller controls the motor's operation. When controlling the motor's operation, the motor controller can adjust according to different operating conditions of the catering vehicle. For example, when the catering vehicle is traveling at low speed or generating electricity while parked, the motor controller can adjust the motor's speed and torque. The high-voltage distribution box can integrate multiple functions, such as battery management and charging management.

[0054] The cooking container is detachably connected to the chassis body 410, meaning the cooking container can be connected to the chassis body 410 by bolts or quick-locking. The cooking cabin includes a main cabin 100, a first extension cabin 200, and a second extension cabin 300. The main cabin 100 is divided into a water and electricity area 110, a processing area 120, a preparation area 130, and a storage area 140 along its length from front to back. A compartment 150 is located in front of the water and electricity area 110. An inverter power supply and an AC distribution cabinet are installed inside the compartment 150. The inverter power supply and the AC distribution cabinet are electrically connected. The inverter power supply is used to convert DC power into AC power and output it to the AC distribution cabinet. The AC distribution cabinet is used to distribute and manage the AC power output by the inverter power supply to provide power to various areas. The inverter power supply is electrically connected to a high-voltage distribution box through a high-voltage cable. The first extension cabin 200 and the second extension cabin 300 are respectively located on the left and right sides of the main cabin 100. Both the first extension cabin 200 and the second extension cabin 300 can be folded up or unfolded relative to the main cabin 100.

[0055] It is understood that the cooking vehicle provided in this embodiment of the utility model, by setting a hybrid system on the chassis body 410, connects the engine 420 and the hybrid transmission 430 through a transmission assembly. The hybrid transmission 430 is connected to the drive shaft 450, and the power battery 440 is electrically connected to the motor controller and the high-voltage distribution box through high-voltage cables. The high-voltage distribution box is electrically connected to the inverter power supply used to supply power to each area through high-voltage cables. Powering cooking equipment (such as induction cookers, electric steamers, etc.) through the power battery 440, inverter power supply, and hybrid system eliminates the open flame operation mode of traditional diesel stoves, eradicating the risks of fuel leakage, uncontrolled fire, and explosion. It is especially suitable for bumpy driving, confined spaces, or flammable and explosive environments. The electrically driven processing equipment has no combustion process, eliminating nitrogen oxide and particulate matter emissions, meeting the stringent environmental requirements of indoor environments, ecological protection zones, and other scenarios. The inverter power supply is compatible with solar energy and external power grid charging, further reducing the carbon footprint.

[0056] Furthermore, the engine 420 and the power battery 440 work together intelligently through the hybrid transmission 430. Under low-load conditions, the power battery 440 is prioritized for power supply, reducing engine 420 idling losses. Under high-load conditions, the engine 420 and the power battery 440 jointly supply power, and energy recovery technology (such as regenerative braking) improves overall energy efficiency, significantly reducing fuel consumption (overall energy efficiency improvement of more than 30%). In extreme environments, the engine 420 can serve as a backup power source to replenish the power battery 440, ensuring continuous power supply under extreme conditions.

[0057] The inverter integrates the power battery 440, generator 420, and external power grid input, implementing a priority power supply strategy (such as battery priority and emergency power replenishment) through a high-voltage distribution box to ensure continuous operation during power outages or extreme environments. The motor controller and high-voltage distribution box monitor the power load of processing area 120 and storage area 140 in real time, dynamically adjusting power distribution (such as automatically increasing power supply during peak cooking periods) to avoid energy waste and extend battery life. Processing equipment (such as induction cookers and electric steamers) is centrally controlled via a PLC control box, supporting preset cooking programs and precise temperature adjustment, reducing manual intervention and operational errors, and improving work efficiency. The power system eliminates the need for complex maintenance such as fuel filtration and burner cleaning. The power battery 440 and inverter adopt a modular design, supporting rapid replacement or upgrades, reducing field maintenance time by more than 60%. The sealed design of the inverter and power battery 440 within compartment 150 ensures stable power supply in harsh environments such as rain and sandstorms. Combined with the rapid deployment function of the expansion compartment, it achieves rapid response in all weather and terrain conditions.

[0058] The kitchen vehicle provided in this embodiment of the utility model achieves three major technological breakthroughs: replacing open flame stoves with electromagnetic cooking appliances, modular expansion of the cabin, and intelligent energy management. It systematically solves the technical defects of traditional kitchen vehicles in terms of safety, energy efficiency, space utilization, and environmental adaptability. It is especially suitable for scenarios with extremely high requirements for rapid deployment, safety, reliability, low carbon emissions, and quiet operation, such as military field operations and disaster relief.

[0059] Figure 6 This is a structural layout diagram of the cooking compartment in the cooking vehicle provided in this embodiment of the utility model (the extended compartment is in the unfolded state). Figure 7 This is a structural layout diagram of the cooking compartment in the cooking vehicle provided in this embodiment of the utility model (the extended compartment is in a retracted state).

[0060] See Figure 6 When the first extension compartment 200 and the second extension compartment 300 are in the unfolded state, both the first extension compartment 200 and the second extension compartment 300 can be equipped with a movable workbench, a folding table and a trolley.

[0061] See Figure 7 When the first extension compartment 200 and the second extension compartment 300 are in the retracted state, the movable workbench, folding table and trolley are stored in the main compartment 100.

[0062] Continue reading Figures 1 to 3 In some embodiments of this utility model, the chassis body 410 includes a frame 411 and a cab 412. The frame 411 may be made of high-strength alloy steel. The cab 412 is located in front of the frame 411. The engine 420, hybrid transmission 430 and power battery 440 are all located on the frame 411. A warning light 460 is provided on the top of the cab 412. A marker light 470 is provided on the side of the frame 411. A skirt box 480 and a sewage tank 490 are provided at the bottom of the frame 411.

[0063] The engine 420 can be positioned slightly forward and in the middle of the frame 411. This layout is beneficial for the vehicle's center of gravity distribution, making the cooking vehicle more stable during operation. The engine 420 can be mounted at an angle, for example, at a 30° angle to the plane of the frame 411. This mounting method facilitates the connection of the engine 420 to other components, such as the hybrid transmission 430, without increasing the height of the frame 411, and also improves the heat dissipation of the engine 420.

[0064] The hybrid transmission 430 can be positioned close to the engine 420 and connected to it via a specially designed mounting bracket. This bracket can be made of aluminum alloy, reducing weight while maintaining sufficient strength. The transmission's output shaft is coaxial with the drive shaft 450 to ensure efficient power transmission. Cooling fins can be installed around the transmission, and it is equipped with dedicated cooling pipes connected to the vehicle's cooling system to ensure effective heat dissipation under high loads.

[0065] The power battery 440 can be installed at the rear of the frame 411. This helps to balance the weight distribution between the front and rear of the vehicle. The power battery 440 can adopt a modular design, with multiple battery modules neatly arranged in a specially designed battery compartment at the rear of the frame 411. The battery compartment is designed to be fireproof, explosion-proof, and waterproof. For example, the outer shell of the battery compartment can be made of fireproof and heat-insulating materials, and drainage holes are provided inside to prevent rainwater accumulation. Smoke detectors and temperature sensors are also installed to monitor the safety conditions inside the battery compartment in real time.

[0066] The warning light 460 on the roof of the cab 412 can be a red-blue dual-color flashing warning light 460. The brightness of the warning light 460 is adjustable and it has multiple flashing modes, such as single flash and double flash. The warning light 460 can be operated through a control switch inside the cab 412, which is convenient for use in special situations, such as when performing emergency catering support tasks, to warn other vehicles and pedestrians to give way.

[0067] The side marker lights 470 of the vehicle frame 411 may include turn signals and position lights 180. The turn signals may use high-brightness LEDs with a fast flashing frequency to ensure clear indication of the turning direction to other vehicles and pedestrians when turning. The position lights 180 may be evenly distributed along the edge of the side of the vehicle frame 411 to clearly display the outline of the cooking vehicle at night or in low visibility conditions, thereby improving vehicle safety.

[0068] The skirt box 480 can be used as a tool storage box to store tools needed for the maintenance and repair of the cooking vehicle, such as wrenches and screwdrivers. On the other hand, the skirt box 480 can also serve as storage space for auxiliary equipment of some cooking equipment, such as spare fuel canisters for stoves or baking trays for ovens.

[0069] The capacity of the wastewater tank 490 can be designed according to the scale of use of the kitchen vehicle. The wastewater tank 490 can be equipped with both manual and automatic discharge methods. Manual discharge is operated via a drain valve located at the bottom of the wastewater tank 490 and can be used in some simple parking areas. Automatic discharge can be connected to the vehicle's control system; when the wastewater in the tank 490 reaches a certain level, the discharge program is automatically initiated, discharging the wastewater into a designated wastewater treatment facility. A filter device can be installed at the discharge port of the wastewater tank 490 to prevent solid impurities from being discharged and polluting the environment.

[0070] Continue reading Figure 1 and Figure 3 In some embodiments of this utility model, the kitchen vehicle also includes a delivery drone 500, which is adapted to be stored in the main cabin 100. A tail plate 600 is provided at the rear of the frame 411. The tail plate 600 is adapted to switch between a folded state and a flat state. In the folded state, the tail plate 600 is attached to the kitchen cabin; in the flat state, the tail plate 600 serves as a take-off and landing platform for the delivery drone 500.

[0071] A dedicated storage area for the delivery drone 500 is provided within the main cabin 100. This storage area can be located at the top or side of the main cabin 100, for example, in the space above the storage area 140. The shape and size of the storage area are precisely designed according to the shape and folded dimensions of the delivery drone 500. A frame structure can be used, with fixing points and straps on the frame. When the delivery drone 500 is stored, its wings, landing gear, and other components can be secured to the fixing points on the frame using straps, preventing damage from shaking or collisions during the movement of the delivery vehicle.

[0072] The flight capabilities of the delivery drone 500 should be adapted to the service range of the catering vehicle. For example, its maximum flight radius can be set to 5-10 kilometers, which is sufficient to cover the delivery needs of a certain area around the catering vehicle. The maximum payload of the drone can be designed according to common meal portions and the number of utensils, such as being able to carry 5-10 kilograms of items, so that multiple meals and corresponding utensils can be delivered at once.

[0073] The delivery drone 500 employs a multi-rotor design, such as a quadcopter or a hexcopter. This multi-rotor design provides better flight stability and maneuverability. For the rotor material, high-strength, lightweight carbon fiber can be used, reducing the drone's weight while ensuring rotor strength and rigidity.

[0074] The delivery drone 500 is equipped with an intelligent navigation system, enabling it to fly accurately along pre-set delivery routes. This navigation system integrates GPS, BeiDou, and other satellite positioning systems, while also utilizing ground-based base station signals for positioning correction, thus improving accuracy. The drone's cargo compartment can be designed with an insulated structure, using materials such as polystyrene foam to ensure the food remains at a suitable temperature during delivery. Furthermore, the cargo compartment can be equipped with dividers to separate different types of food or goods, preventing them from being crushed or contaminated.

[0075] The tailgate 600 can be switched between a folded and a flat position via a hydraulic system or an electric push rod system. Taking the hydraulic system as an example, a hydraulic pump and a hydraulic cylinder are installed on the frame 411, with the hydraulic pump providing power to the hydraulic cylinder. When it is necessary to switch the tailgate 600 from a folded to a flat position, the hydraulic pump is activated, and the hydraulic cylinder pushes the tailgate 600 to unfold until it reaches the flat position. A spherical bearing can be installed at the connection point of the tailgate 600 to ensure the flexibility and stability of the tailgate 600 during the switching process. Simultaneously, a sealing device can be installed at the connection point between the tailgate 600 and the cooking compartment. When the tailgate 600 is in the folded position, the sealing device can prevent dust, rainwater, etc., from entering the gap between the tailgate 600 and the cooking compartment.

[0076] When the tailplate 600 is used as a takeoff and landing platform, it can be equipped with clear takeoff and landing markings, such as circular takeoff and landing point markers and arrow directional markers. These markings can be made of fluorescent materials, ensuring clear visibility at night or in low-visibility conditions. Furthermore, the tailplate 600 can be equipped with lighting equipment, such as LED light strips, to provide sufficient light for the drone's takeoff and landing. A charging port can also be installed on the tailplate 600, allowing the drone's battery to be charged after landing, facilitating the next flight mission.

[0077] Continue reading Figures 1 to 3 In some embodiments of this utility model, the cooking cart also includes at least four leveling legs 700, which are located near both ends of the frame 411, that is, at the front and rear positions of the frame 411.

[0078] The leveling outriggers 700 adopt a symmetrical layout, for example, one leveling outrigger 700 is set at each of the four corners of the bottom of the frame 411. This layout can ensure that the force is evenly distributed during the leveling process of the cooking vehicle, thereby improving the stability of the vehicle.

[0079] The leveling outrigger 700 employs a telescopic structure, consisting of an inner tube and an outer tube. The inner tube slides up and down within the outer tube, enabling the outrigger's extension and retraction. The adjustment mechanism of the leveling outrigger 700 can be hydraulically driven or electrically driven by a screw. Taking hydraulic drive as an example, the hydraulic system consists of a hydraulic pump, a hydraulic cylinder, and hydraulic lines. The hydraulic pump provides power to the hydraulic cylinder, causing the piston of the hydraulic cylinder to push the inner tube to extend or retract. A stroke sensor can be installed on the hydraulic cylinder to accurately measure the extension and retraction length of the outrigger, facilitating precise leveling. Electrically driven by a screw, on the other hand, uses a motor to rotate a screw, causing a nut that meshes with the screw to move up and down along the screw, thus achieving the extension and retraction of the outrigger. This drive method offers high adjustment precision.

[0080] The leveling outriggers 700 can perform leveling operations on the cooking vehicle when it is parked. When the cooking vehicle is parked on uneven ground, the extension and retraction of the leveling outriggers 700 can be controlled to bring the vehicle frame 411 to a level state. A level sensor installed on the frame 411 can be used to detect the levelness of the frame 411. The level sensor feeds the levelness information back to the control system, and the control system controls the extension and retraction of the leveling outriggers 700 based on the feedback information until the frame 411 reaches a preset level accuracy, such as a levelness error within ±0.5°.

[0081] During the operation of the kitchen cart, the leveling outriggers 700 also bear some of the load, distributing the weight of the frame 411 and reducing the load on the wheels. Especially when the kitchen cart is engaged in cooking operations, the vibration of the cooking equipment and the movement of personnel may cause the vehicle to sway. The leveling outriggers 700 can increase the stability of the vehicle, prevent the vehicle from tilting or swaying excessively, and ensure the smooth progress of cooking operations.

[0082] It should be noted that the kitchen vehicle is also equipped with extension cabin support legs 800, pull ladder 900, and foot ladder 910. Extension cabin support legs 800 are used to support the corresponding extension cabin, while pull ladder 900 and foot ladder 910 facilitate personnel climbing the kitchen vehicle.

[0083] Water and electricity zone 110 is the core energy supply area of ​​the cooking cabin. A water supply module is located below water and electricity zone 110, which is used to supply water to processing zone 120 and preparation zone 130. A power supply module is located above water and electricity zone 110, which is used to supply power to processing zone 120, preparation zone 130 and storage zone 140.

[0084] The water supply module includes a booster pump and a water storage tank, a water purifier, a purified water tank, a water heater, and a hot water tank connected in sequence. The booster pump is installed on the pipes connecting the water storage tank, water purifier, purified water tank, water heater, and hot water tank. The water storage tank is connected to the water purifier, which uses a multi-stage filtration system including PP cotton, activated carbon, and ultrafiltration membranes to effectively remove impurities, odors, and bacteria from the water. The purified water flows into the purified water tank for storage. The booster pump pumps water from the purified water tank to the water heater, which heats the water. The heated water then flows into the hot water tank for storage. The booster pump is also used to pump water from the purified water tank to other areas where water is used.

[0085] The power supply module includes a PLC control box, whose power input terminal is electrically connected to the output terminal of the AC distribution cabinet. The PLC control box can add monitoring functions for the inverter power supply status, monitoring parameters such as voltage, current, and frequency in real time. When abnormalities occur, it promptly issues alarm signals and takes corresponding protective measures. It can also add load control functions, enabling intelligent management and control of different loads, such as rationally allocating power according to load priority and operating status.

[0086] In addition, to achieve remote monitoring and management, communication modules such as RS485, Ethernet, and GPRS can be added to the PLC control box and AC power distribution cabinet. Through these communication interfaces, the operating status and fault information of the power supply module can be uploaded to the remote monitoring center, and control commands from the remote monitoring center can also be received to achieve remote control and management.

[0087] More protection functions can be added to the AC distribution cabinet, such as overcurrent protection, overvoltage protection, undervoltage protection, and leakage protection, to ensure the safe and reliable operation of the power supply system. At the same time, the protection functions can be intelligently managed; for example, protection parameters can be flexibly set according to different load characteristics and operating requirements, improving the accuracy and reliability of the protection.

[0088] Processing area 120 includes a staple food processing area 121 and a side dish processing area 122 arranged opposite to each other; the countertop of staple food processing area 121 is equipped with an electric pressure cooker and a rice steamer; the countertop of side dish processing area 122 is equipped with an induction cooker, a steam oven and a condiment cabinet, the condiment cabinet adopts a layered design, which can hold various condiment bottles such as salt, sugar, and soy sauce; both staple food processing area 121 and side dish processing area 122 are equipped with exhaust hoods.

[0089] In other words, processing area 120 is equipped with complete cooking equipment, and each piece of cooking equipment is powered by electricity, which can improve the safety of the cooking cabin and eliminate the use of open flames.

[0090] The preparation area 130 has a first side and a second side arranged opposite each other. The countertop on the first side is equipped with a sink, a sterilizer, and a meat grinder. A garbage disposal unit is installed under the sink, which not only facilitates the sorting and washing of food but also allows food scraps to be ground and disposed of. The countertop on the second side is equipped with a vegetable cutter and a refrigerated work surface. Above the preparation area 130 are wall cabinets and a display screen. The wall cabinets are used for storing items, and the display screen can be used to display images or videos.

[0091] Storage area 140 is mainly used for storing food ingredients, tableware, and kitchen utensils. Storage area 140 is equipped with a freezer and a sterilizer. The freezer can reach a temperature as low as -18°C and is used to store frozen food ingredients such as meat and fish. The sterilizer is used to store tableware and kitchen utensils.

[0092] The compartment 150 is located in front of the main compartment 100's water and electricity area 110. It separates the main working area of ​​the main compartment 100 from the main working area via a partition. An inverter power supply and AC distribution cabinet are installed inside the compartment 150 to prevent moisture and oil contamination from damaging the circuits in the main working area, reducing the risk of short circuits. The inverter power supply converts direct current into stable alternating current, meeting the power needs of various electrical devices within the cooking container. This allows the water and electricity area 110, processing area 120, and storage area 140 to achieve off-grid power supply via the inverter power supply, reducing reliance on external water purification trucks and refrigerated trucks.

[0093] The first extension compartment 200 and the second extension compartment 300 are respectively located on the left and right sides of the main compartment 100. Both the first extension compartment 200 and the second extension compartment 300 can be folded or unfolded relative to the main compartment 100. In the unfolded state, both the first extension compartment 200 and the second extension compartment 300 can be equipped with auxiliary equipment such as movable workbenches, folding tables, storage cabinets, insulated boxes, trash cans, and trolleys for quick cooking equipment. In the folded state, the auxiliary equipment is stored in the aisle of the main compartment 100 and fixed on the workbench, enabling self-transportation without the need for other vehicles to support the venue, thereby improving self-sufficiency.

[0094] The first expansion cabin 200 and the second expansion cabin 300 can have identical structures, both including a cabin body, an expansion mechanism, and a bottom carriage. The cabin body is typically made of imported aluminum skin and polyurethane sandwich composite panels, including side panels, flaps, and end panels. The side panels consist of a linked top side panel and a linked bottom side panel, with the flaps unfolding and retracting based on the principle of parallel linkage. The manually operated flap-type double-sided expansion cabin expands by manually pushing and pulling the flaps. Operators sequentially push and pull the side panels of the double-sided expansion cabin, causing the top side panel to drive the bottom side panel to unfold or retract in a linked manner, thereby changing the internal space size of the cabin. The bottom carriage is used to automatically adjust the cabin's balance after the side cabins are unfolded, ensuring the cabin remains stable after expansion.

[0095] When the modular container needs to be expanded, i.e., when the first expansion compartment 200 and the second expansion compartment 300 are deployed, the operator manually pushes and pulls the side panels, causing the side top and side bottom panels to unfold in tandem. Simultaneously, the bottom sliding frame automatically adjusts its balance, gradually increasing the internal space of the container until the desired expansion state is achieved. This effectively increases internal space, improves space utilization, and allows for flexible adjustment of space size according to actual needs.

[0096] When the modular container needs to be retracted, that is, when the first extension compartment 200 and the second extension compartment 300 are retracted, the operator reverses the operation, pushes the side panels back to their original positions, and the side top panel and side bottom panel are retracted accordingly, and the modular container returns to its initial retracted state.

[0097] The expansion and folding operation of the manually operated flap-type double-sided extendable container is relatively simple, and can generally be completed by two operators within 2 minutes, without the need for complex equipment or technical support. Compared with other expansion methods, the manually operated flap structure has a lower cost, and due to its relatively simple structure, it has better reliability and maintainability.

[0098] It is understood that the cooking vehicle provided in this embodiment of the utility model has a cooking cabin that divides the main cabin 100 from front to back into a water and electricity area 110, a processing area 120, a preparation area 130, and a storage area 140. A compartment 150 is provided in front of the water and electricity area 110. An inverter power supply and an AC power distribution cabinet are installed inside the compartment 150. The inverter power supply and the AC power distribution cabinet are electrically connected. The inverter power supply is used to convert DC power into AC power and output it to the AC power distribution cabinet. The AC power distribution cabinet is used to distribute and manage the AC power output by the inverter power supply to provide power to various areas.

[0099] This setup, with the main cabin 100 zoned according to operational flow and combined with the isolated power supply of the compartment 150, forms a self-sufficient operational unit. This creates a complete operational chain between the water and electricity area 110 (energy and water supply), processing area 120 (food processing), preparation area 130 (cooking setup), and storage area 140 (material management). Cross-area transport is eliminated, reducing reliance on external water purification trucks, refrigerated trucks, etc., and shortening operational routes, thus improving efficiency. Simultaneously, the inverter converts DC power into stable AC power and outputs it to the AC distribution cabinet. The AC distribution cabinet distributes and manages the AC power output from the inverter to power various areas. This meets the power needs of various electrical equipment within the cooking cabin, enabling the water and electricity area, processing area, and storage area to operate off-grid, preventing moisture and oil contamination from corroding circuits in the main operational area and reducing the risk of short circuits.

[0100] Meanwhile, by setting up a first extension compartment 200 and a second extension compartment 300 on the left and right sides of the main compartment 100, both the first extension compartment 200 and the second extension compartment 300 can be folded up or unfolded relative to the main compartment 100. In the unfolded state, the extension compartment increases the operating area by approximately 50%, supporting large-scale packaging and multi-person collaborative operations, ensuring the catering needs of thousands of people. Both the first extension compartment 200 and the second extension compartment 300 can be equipped with auxiliary equipment (such as movable workbenches, folding tables, storage cabinets, insulated boxes, trash cans, and trolleys for rapid cooking equipment), improving equipment reuse rates. In the folded state, the volume of the cooking container can be reduced, facilitating transportation or deployment in narrow spaces. Auxiliary equipment can be stored in the aisles of the main compartment 100 and fixed to the workbench, enabling self-transportation without the need for other vehicles, thereby improving self-sufficiency.

[0101] See Figures 1 to 3 In some embodiments of this utility model, an indoor air conditioning unit is provided above the water and electricity zone 110, and an outdoor air conditioning unit connected to the indoor air conditioning unit is provided in the compartment 150.

[0102] This setup, combining the indoor and outdoor units of the air conditioner, can effectively regulate the temperature and humidity inside the cooking cabin, providing a comfortable working environment for the cooks.

[0106] In addition, in special circumstances, such as equipment failure or chemical leaks that may generate smoke, smoke sensors can detect and send signals in a timely manner, so that staff can react quickly and take appropriate measures.

[0107] The temperature and humidity sensors can accurately measure the temperature and humidity inside the main cabin 100 in real time and transmit the data to the control system. Based on this data, staff can adjust the temperature and humidity inside the main cabin 100 to ensure they are maintained within a suitable range, providing a comfortable working environment for cooks, while also facilitating food storage and the normal operation of equipment.

[0108] Furthermore, precise monitoring and control of temperature and humidity can enable the rational use of energy, avoid energy waste, and reduce energy consumption. In addition, a suitable temperature and humidity environment helps reduce the growth of microorganisms such as bacteria and mold, reducing environmental pollution and meeting environmental protection requirements.

[0109] Among them, ultraviolet disinfection lamps emit ultraviolet light that destroys the DNA structure of microorganisms, thereby achieving the effect of disinfection and sterilization. In the kitchen cabin, the air and object surfaces within the main cabin can be disinfected, effectively killing harmful microorganisms such as bacteria, viruses, and mold, reducing the risk of disease transmission, and protecting the health of kitchen staff.

[0110] Especially in the food storage area 140, ultraviolet disinfection lamps can disinfect the stored food to a certain extent, extend the shelf life of the food, ensure the freshness and quality of the food, and prevent the food from spoiling due to microbial contamination.

[0111] Among them, the analysis camera can monitor the operating status of cooking equipment, electrical equipment and other equipment in the main cabin 100 in real time. Through image analysis technology, it can promptly detect potential faults in the equipment, such as wear, deformation and leakage of equipment parts, and provide early warning so that staff can carry out timely repairs and replacements to ensure the normal operation of the equipment.

[0112] In addition, it allows for the supervision of kitchen staff's operations, ensuring that their procedures are standardized and safe, and preventing accidents or food quality issues caused by improper human intervention. It also facilitates the assessment and management of kitchen staff.

[0113] Multiple cameras can provide comprehensive monitoring of all areas within the main cabin 100, including the processing area 120, storage area 140, preparation area 130, and water and electricity area 110. This allows for real-time monitoring of personnel activities and equipment operation within the main cabin 100. If any abnormal behavior or safety hazard is detected, immediate measures can be taken to address it and ensure the safety of the main cabin 100.

[0114] It facilitates real-time supervision and management of kitchen staff by managers, improving work efficiency and management level. Simultaneously, it can serve as a basis for work records, facilitating traceability and analysis of the work process.

[0115] In addition, in emergency situations such as fires, explosions, or injuries, the footage captured by the cameras can provide emergency rescue personnel with on-site information, helping them to quickly formulate rescue plans and improve the efficiency and accuracy of emergency response.

[0116] Continue reading Figures 1 to 3 In some embodiments of this utility model, both the first expansion compartment 200 and the second expansion compartment 300 are provided with outward-opening skylights 210 and site lighting lamps 220 near the top, and either the first expansion compartment 200 or the second expansion compartment 300 is provided with double doors 230.
