Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of personal cooling equipment, and in particular to an integrated liquid cooling cooling clothing system applied to an electric motorcycle (two-wheeled or three-wheeled). BACKGROUND

[0002] In the field of high-temperature outdoor work, especially with the popularity of electric motorcycles (including two-wheeled and three-wheeled vehicles) in express delivery, take-out service and other industries, workers are facing severe heat stress challenges for a long time. Traditional cars can provide a cool environment for the closed cabin through the vehicle-mounted air conditioning system, however, electric motorcycles cannot carry and use traditional compressor refrigeration air conditioners due to their open driving structure, which exposes the driver to the sun and high-temperature environment, and the work comfort and safety need to be solved.

[0003] To solve this problem, the existing technology mainly relies on personal active cooling equipment, but all have significant limitations and cannot meet the specific needs of electric vehicle users. Active air-cooled cooling clothing promotes sweat evaporation through built-in fans, but its efficiency decreases sharply in high-temperature and high-humidity environments, and the fan is noisy and the clothing is bulky, which seriously affects the flexibility and comfort of electric vehicle riding. Although liquid-cooled cooling clothing has improved cooling efficiency, early products mostly use integrated backpack design, integrating water tank, pump body, battery and other heavy components on the clothing, and the weight often exceeds 4 kg. This design is a heavy burden for electric vehicle users who need to get on and off the vehicle frequently and move long distances, which greatly increases physical exertion, is fundamentally contradictory to the light and flexible travel characteristics of electric vehicles, and leads to poor user experience and difficult popularization and application. SUMMARY

[0004] To solve the above problems, the present application provides an innovative cooling solution designed specifically for electric motorcycle scenarios, which can effectively utilize the space and energy of the vehicle itself, fundamentally avoid the user carrying heavy components, and have a minimalist and intelligent connection and separation experience, so as to realize the real "on-the-go, off-the-go", and meet the actual needs of a large number of electric vehicle users.

[0005] To achieve the above object, the technical scheme adopted by the present application is: a portable air-conditioned clothing system for electric motorcycles, comprising a vehicle-mounted vehicle-mounted cold source device mounted on an electric vehicle, a water tank for containing a heat dissipation medium, a pump body in communication with the water tank, and a refrigeration unit for refrigerating the heat dissipation medium; a cooling garment having a flow channel for circulating the heat dissipation medium formed therein; a quick connection interface assembly, the assembly comprising a first interface part and a second interface part that can be quickly connected and separated by magnetic attraction, the first interface part being connected to the vehicle-mounted cold source device, and the second interface part being connected to the cooling garment; the pump body is used to drive the heat dissipation medium to circulate in a closed loop formed by the vehicle-mounted cold source device, the first interface part, the second interface part and the flow channel of the cooling garment.

[0006] Further, the first interface part is an A-end interface provided on the vehicle-mounted vehicle-mounted cold source device or the body of the electric motorcycle, and the second interface part is a B-end interface provided on the side of the cooling garment; the A-end interface and the B-end interface are respectively embedded with magnetic attraction elements that attract each other in the interfacing surface. The inlet of the pump body is in communication with the water tank, and the outlet of the pump body is connected to the water inlet end of the A-end interface through a pipeline; the water outlet end of the A-end interface is connected to the inlet of the refrigeration unit through a pipeline, and the outlet of the refrigeration unit is connected back to the water tank through a pipeline; the water inlet end and the water outlet end of the B-end interface are respectively connected to the garment water inlet end and the garment water return end of the cooling garment through flexible water pipes; the A-end interface and the B-end interface are detachably connected to form a closed circulation path for the heat dissipation medium from the vehicle-mounted cold source device to the cooling garment and back to the vehicle-mounted cold source device in the connected state.

[0007] Further, the refrigeration unit comprises a compressor, a condenser, a throttling element and an evaporator; the compressor, the condenser, the throttling element and the evaporator are connected in sequence by pipelines to form a vapor compression refrigeration cycle circuit; the evaporator is arranged to cool the heat dissipation medium.

[0008] Further, the system further comprises a heat exchange core having a first cavity and a second cavity that are thermally insulated from each other; the first cavity is connected in series on the return pipeline between the water outlet end of the A-end interface and the water tank for flowing the heat dissipation medium returned from the cooling garment; the evaporator is accommodated in the second cavity for heat exchange with the heat dissipation medium flowing through the first cavity through the partition wall of the heat exchange core.

[0009] Further, the first cavity is a coiled pipe flow channel coiled outside the second cavity or a sandwich flow channel fitted with the outer wall of the second cavity.

[0010] Furthermore, magnetic elements that attract each other are embedded in the mating surfaces of the A-end interface and the B-end interface, which are used to achieve rapid positioning and adsorption during docking.

[0011] Furthermore, the A-end interface is equipped with a fluid pump switch. When the A-end interface is connected to the B-end interface, the B-end interface triggers the fluid pump switch to turn on the power supply circuit of the pump body; when the two are separated, the fluid pump switch automatically cuts off the circuit.

[0012] Furthermore, the fluid pump switch is a mechanical limit switch, with its actuating component facing and protruding from the inner side of the mating surface of the A-end interface. When the interfaces are mated, it is triggered by being squeezed by the mating surface of the B-end interface.

[0013] Furthermore, a normally closed check valve is provided in the flow channel of both the inlet and outlet of the A-end interface; a push mechanism corresponding to the check valve is provided on the mating surface of the B-end interface; when the interfaces are mated, the push mechanism pushes open the check valve to connect the water path.

[0014] Furthermore, a one-way valve is also provided inside the flow channel of the water inlet of the B-end interface. The one-way valve is closed in its natural state to seal the water passage, and opens under the action of water flow pressure in the inflow direction.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention integrates an electric motorcycle, specialized cooling clothing, and a magnetic quick-connect interface, providing electric motorcycle users with a feasible personal air conditioning solution and directly breaking through the long-standing technical bottleneck of "electric vehicles being unable to carry traditional air conditioners." Previously, workers operating traditional electric vehicles exposed to high outdoor temperatures could only rely on carrying heavy, inefficient personal cooling equipment, resulting in a very poor experience. This invention, through its system architecture, securely integrates a heavy-duty vehicle-mounted cooling source device into the electric motorcycle, allowing the cooling clothing to retain only lightweight airflow channels. This revolutionary change achieves "vehicle-borne weight, lightweight clothing," enabling electric motorcycle users to enjoy a continuous and powerful cooling experience.

[0017] In terms of cooling efficiency, the system utilizes the stable power and space provided by the electric motorcycle itself, and is equipped with a refrigeration unit based on compression cycle to ensure sufficient cooling power. The coolant circulates in channels covering the core areas inside the clothing, achieving targeted cooling of the torso and head. The effect is far superior to traditional air cooling or simple liquid cooling solutions, and it can create a reliable personal microclimate environment for the user even under extreme high temperatures.

[0018] The system's core convenience stems from its magnetic interface design. Utilizing strong magnetic attraction, the interface enables seamless "one-second connection and automatic linkage." Upon connection, not only does the water circuit automatically connect, but the water pump circuit also starts simultaneously, allowing for "ready to use upon boarding"; upon separation, it automatically cuts off power and seals, stopping immediately upon leaving the vehicle. This intelligent linkage perfectly matches the frequent boarding and alighting rhythms of users such as delivery and courier services, elevating convenience to a whole new level.

Detailed Implementation

[0029] Please see Figures 1-9 As shown, this invention relates to an innovative cooling solution specifically designed for electric motorcycles. This solution must effectively utilize the vehicle's own space and energy, fundamentally avoiding the need for users to carry heavy components, while also providing a minimalist and intelligent connection and disconnection experience, thus achieving true "ready to use upon boarding and ready to go upon disembarking," to meet the practical needs of a wide range of electric motorcycle users. The system uses an innovative quick-connect interface component 10 to tightly connect a movable onboard cooling source device 300 to the cooling clothing 400 worn by the user, achieving automatic circulation and temperature control of the heat dissipation medium.

[0030] The system mainly consists of three parts: an on-board cooling source device 300, cooling clothing 400, and a quick-connect interface assembly 10 located between the two. The on-board cooling source device 300 is typically mounted on a vehicle such as an electric bicycle, and internally includes a liquid storage tank 310, a pump 320 for driving liquid circulation, and a complete vapor compression refrigeration system. The refrigeration system consists of a compressor 331, a condenser 332, a throttling element 333, and an evaporator 334 connected sequentially via piping. The evaporator 334 is integrated into a dedicated heat exchange core 340, which contains two isolated but heat-exchangeable chambers.

[0031] The specific structure of the vehicle-mounted cooling source device 300 is as follows: Physically, this device is an integrated large box or enclosure structure. Its outer shell 350 is typically made of engineering plastic or metal, and internally houses and fixes core components such as a water tank 310, a pump body 320, and a refrigeration unit. This enclosure can also integrate a power supply (such as a large-capacity battery pack; in another embodiment, it can be powered directly by the electric vehicle or motorcycle's own battery) and a user control panel 351. The control panel 351 includes a power switch, a temperature adjustment button, a flow rate adjustment knob, and a display screen showing current water temperature, power level, and other information for easy user operation and monitoring. The refrigeration unit cools the heat dissipation medium through a heat exchange core 340.

[0032] The cooling garment 400 is a hooded vest design, specifically designed to meet the head cooling needs of outdoor workers, and includes a hood connected to the main body of the garment. This hood also contains independent internal flow channels 420, which, together with the S-shaped flow channels 410 within the main body of the garment, form a complete internal cooling flow channel system. The main body of the garment has a main water inlet 430 and a return water outlet 440 at the back of the neck. The flow path of the heat dissipation medium is as follows: after entering through the garment inlet 430, it is diverted to the main body flow channels 410 and the hood internal flow channels 420, cooling the torso and head respectively, before converging back to the main return water outlet 440. These two ports are connected to the corresponding ports of the B-end interface 200 of the quick-connect interface assembly 10 via flexible water pipes 510.

[0033] The quick connection interface component 10 is the key component of this invention. The specific structure and working mechanism of its A-end interface 100 and B-end interface 200 are detailed below.

[0034] 1. Structure of A-end Interface 100: The body of A-end interface 100 is a first outer shell 101 made of POM engineering plastic, with a flat mating surface on top. Two annular neodymium iron boron magnetic elements (first magnets 130) are symmetrically embedded in the mating surface. An A-end magnet through hole 131 is opened in the center of the magnet, which forms part of the water channel. A-end interface 100 has a first water inlet A1 and a first water outlet A2, wherein the first water inlet A1 is used to receive coolant from the vehicle-mounted cooling source device 300, and the first water outlet A2 is used to return the heated coolant to the vehicle-mounted cooling source device 300. In each water channel, below the magnet through hole 131, a normally closed check valve 120 is provided. The check valve 120 includes a valve core 121 made of POM material and a stainless steel spring 123. The flow channel is designed with a small-diameter section 125 and a large-diameter section 126. The valve core 121, under the action of the spring 123, forms a seal with the end face of the small-diameter section 125. Inside the first housing 101, a receiving groove 150 is provided on the side, housing a mechanical limit switch 210 as a fluid pump switch. Its button faces inwards towards the mating surface. A wire hole 151 is located at the bottom of the receiving groove 150 for the lead wire to pass through. A ring of silicone sealing gasket 160 is also adhered to the mating surface.

[0035] 2. Structure of B-end interface 200: The bottom mating surface of the second outer shell 201 of the B-end interface 200 is fitted with a second magnet 230 corresponding to the A-end. The B-end interface 200 has a second water inlet B1 and a second water outlet B2, wherein the second water outlet B2 is connected to the water inlet pipe of the garment, and the second water inlet B1 is connected to the water return pipe of the garment. A cylindrical pushing mechanism (pushing support 220) is provided at the position directly opposite the A-end check valve 120. The diameter of the pushing support 220 is slightly smaller than the diameter of the small diameter end of the A-end magnet through hole 131 of the A-end first magnet 130, and its height is designed to effectively push the A-end check valve 120 upward during docking. Inside the B-end interface 200, in the flow channel corresponding to the second water inlet B1, a silicone one-way valve plate 250 is provided, which has an "I"-shaped slit in the center. In the natural state, the slit closes to seal the water passage. On the mating surface of the second housing 201, a ring of protruding ribs 240 is also designed to precisely press the sealing silicone gasket 160 of end A during mating.

[0036] Docking Process: When the user brings the B-end interface 200 close to the A-end interface 100, the first magnet 130 and the second magnet 230 of both sides generate a strong magnetic attraction, achieving automatic alignment and adsorption. At the moment of docking, the annular protrusion 240 of the B-end presses against the sealing silicone gasket 160 of the A-end, forming a reliable seal. At the same time, the push-up support 220 of the B-end passes through the through holes of both magnets (through hole 131 of the A-end magnet and through hole 231 of the B-end magnet), opening the valve core 121 of the A-end check valve 120, disengaging it from the small-diameter section 125, and connecting the water passage. When the interface is fully docked, the housing of the B-end interface 200 presses against the limit switch 210 button of the A-end, closing its internal contacts, thereby activating the water pump circuit and starting the system.

[0037] Pump body 320 pumps the heat dissipation medium (which can be water or an aqueous solution of ethylene glycol) from water tank 310 into the cooling garment 400 through the first inlet A1, and then into the cooling garment 400 through the second outlet B2 of the A-end interface 100 and B-end interface 200. The heat dissipation medium is divided into two paths at the garment's main inlet: one flows through the garment's main body channel 410, and the other flows through the inner channel 420 of the hood, thus simultaneously and efficiently dissipating heat from the worker's torso and head—the two core heat-generating areas. The heat dissipation medium, after absorbing heat, flows out from the garment's return outlet 440, returns through the second inlet B1 of the B-end interface 200, and flows out through the first outlet A2 of the A-end interface 100, finally flowing into the first cavity of the heat exchange core 340. At this time, the refrigeration unit operates, and the evaporator 334 cools the liquid flowing back into the first cavity through the metal partition. The cooled liquid returns to the water tank 310, completing the circulation.

[0038] Separation Process: During separation, the limit switch 210 first resets, cutting off the water pump power to prevent dry running. Immediately afterwards, the push-support column 220 at end B retracts, and the check valve 120 at end A closes instantly under the action of spring 123, sealing the water passage at end A. Simultaneously, the one-way valve 250 inside end B closes due to the loss of water pressure, sealing the clothing side (including the main body and hood) piping, forming a double leak-proof guarantee. The entire process achieves water-electricity linkage, automatic on / off switching, and separation-based leak prevention.

[0039] It is also important to note that, in another embodiment, the vehicle-mounted cooling device 300 can be designed to be securely mounted on a suitable location on the electric bicycle, such as under the seat, on the rear seat support, or on the frame near the pedals. When the user sits on the electric bicycle, the B-end interface 200 connected to the cooling clothing 400 naturally hangs down under gravity, placing it very close to the A-end interface 100 fixed to the vehicle body. The first magnet 130 and the second magnet 230 of both sides generate a strong magnetic attraction, automatically guiding the interface to complete precise docking and adsorption. The user does not need any additional operation, achieving a seamless "connection upon boarding" experience.
