Description

Technical Field

[0001] This invention relates to the field of automotive air circulation technology, and in particular to an in-vehicle biochemical system. Background Technology

[0002] Recirculation is a mode of operation for a car's air conditioning system. In this mode, the air exchange channels between the inside and outside of the car are closed. When the fan is off, the airflow inside the car does not circulate. When the fan is on, the air intake only comes from inside the car, creating airflow circulation within the vehicle. Car air conditioners generally have an electric or manual switch for recirculation. When using external recirculation, the air conditioner draws in air from outside the car, while internal recirculation recycles the air inside the car.

[0003] Currently, when a vehicle is in motion, the interior of the passenger compartment forms a sealed space. Although the air inside the vehicle can be refreshed through the air conditioning system, when multiple people are traveling in the vehicle, the odors from smoking and body odor of the passengers can still affect the comfort of other passengers in the relatively sealed cabin. Furthermore, if any passenger has a cold or other infectious disease that can be transmitted through droplets, the health of the other passengers in the vehicle is also threatened. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an in-vehicle biochemical system to solve the problems in the prior art where, when multiple people are traveling in a vehicle, the cabin environment is relatively closed, making it difficult to refresh the air inside the vehicle, which affects the comfort of other passengers. Furthermore, when one of the passengers has a cold or other infectious disease that can be transmitted through droplets, the health of the other passengers in the vehicle is also threatened.

[0005] To achieve the above and other related objectives, the present invention provides an in-vehicle biochemical system, comprising: an automotive air conditioning unit including a plurality of air outlets; a concealed air duct mechanism including: an air inlet pipe and an exhaust assembly, the air inlet pipe being connected to the interior of the vehicle and embedded in the door lintel along the length of the door lintel, the exhaust assembly being embedded in the B-pillar of the door, one end of the air inlet pipe being connected to the exhaust assembly, and the exhaust assembly being connected to the exterior of the vehicle; and a controller, the controller being electrically connected to the exhaust assembly and the automotive air conditioning unit respectively, to control the air outlets of the automotive air conditioning unit in the in-vehicle biochemical mode to be arranged in a direction that guides the air inside the vehicle towards the air inlet pipe, and to control the opening of the exhaust assembly to generate negative pressure in the air inlet pipe to draw in the guided air and exhaust the guided air to the exterior of the vehicle through the exhaust assembly.

[0006] In one embodiment of the present invention, one end of the air inlet pipe opposite to the exhaust assembly is a closed structure, and the air inlet pipe is provided with an exhaust port communicating with the vehicle interior along its length.

[0007] In one embodiment of the present invention, the exhaust port is located inside the window glass of the vehicle door, and the exhaust port and the air inlet pipe form a "ρ" shaped air inlet channel on the cross-section of the air inlet pipe.

[0008] In one embodiment of the present invention, the exhaust assembly includes: a high-speed vortex mechanism, which is vertically mounted on a B-pillar and one side of the high-speed vortex mechanism is connected to the outside of the B-pillar; and a duct, one end of which is connected to the top of the high-speed vortex mechanism and the other end of which is connected to an air inlet duct.

[0009] In one embodiment of the present invention, the high-speed vortex mechanism includes: a turbofan box, with turbofan channels penetrating the upper and lower sides of the turbofan box, and an exhaust port connected to the turbofan channels on one side of the turbofan box; and a vortex fan, which is inserted into the turbofan channels from bottom to top.

[0010] In one embodiment of the present invention, the vortex fan includes: a high-speed motor, which is installed at the bottom of a vortex fan box corresponding to the vortex fan channel; a fan bearing, which is installed at the top of the vortex fan box corresponding to the vortex fan channel; and a fan, the upper end of which is connected to the fan bearing, and the lower end of which is connected to the power output end of the high-speed motor.

[0011] In one embodiment of the present invention, the fan includes: a fan shaft; and blades, the blades being helically mounted on the fan shaft.

[0012] In one embodiment of the present invention, the fan bearing includes: a shaft housing; a central shaft disposed in the middle of the shaft housing; and connecting plates, wherein one side of a plurality of connecting plates is mounted on the central shaft in the circumferential direction along the central shaft, and the other end of the connecting plates is connected to the inner wall of the shaft housing.

[0013] In one embodiment of the present invention, a wiring harness is connected to the lower end of the high-speed vortex mechanism. The wiring harness extends vertically along the B-pillar to the lower half of the car door. The controller is installed in the lower half of the car door, and one end of the wiring harness located in the lower half of the car door is electrically connected to the controller.

[0014] In one embodiment of the present invention, the controller includes: an instruction acquisition unit, which acquires a start instruction for the corresponding seat information; an air vent adjustment unit, which confirms the seat information corresponding to the start instruction, controls the air outlet of the car air conditioning device to be arranged in the guiding direction of the air vent at the door lintel corresponding to the corresponding seat information for air delivery, and controls the air outlet parameters of the air vent, wherein the air outlet is an electronic air outlet; and an air extraction control unit, which controls the start of the high-speed vortex mechanism corresponding to the seat information, so that the corresponding air vent generates negative pressure to draw in the air inside the vehicle guided by the air outlet, and exhausts the air outside the vehicle through the B-pillar.

[0015] As described above, the in-vehicle biochemical device and system of the present invention has the following beneficial effects: By controlling the air outlet of the car's air conditioning system to be aligned with the air exhaust vent at the corresponding seat's door lintel according to the start command of the air circulation scheduling for the designated seats, the air supply direction is aligned with the air exhaust vent at the corresponding seat's door lintel. Furthermore, by controlling the exhaust assembly to create negative pressure on the air inlet pipe at the door lintel, and then generating suction through the air exhaust vent located inside the window glass, the air inside the vehicle guided by the air outlet is drawn out from the exhaust vent at the B-pillar where the exhaust assembly is installed. This achieves a directional flow field and circulation of air inside the vehicle, covering the target occupants within this flow field. At this time, odors, germs, and particulate matter from the target occupants will be isolated from other occupants by the flow field and discharged outside the vehicle, thus achieving biochemical isolation. Moreover, it protects the occupants from the influence of other passengers, such as those smoking, eating (with pungent odors), the odor of infant feces, body odor, and other odors affecting comfort. It also protects the occupants from infectious diseases transmitted by other passengers inside the vehicle, especially infectious diseases spread through droplets. Furthermore, this system can operate with the windows sealed, achieving efficient cabin air circulation and renewal at high speeds without affecting vehicle fuel consumption, NVH (noise, vibration, and harshness) performance. By arranging the air intake duct and exhaust vent along the length of the door frame and forming a "ρ"-shaped air intake duct, a concealed design for the air intake duct and exhaust vent can be achieved, maximizing the suction range for designated seats. Moreover, the air duct structure formed by the air intake duct and exhaust vent is hidden within the A-pillar door frame, without incurring additional aesthetic costs. By installing the exhaust assembly on the B-pillar, while ensuring external air intake, the system is integrated into the vehicle door through the specially designed installation of the air intake duct and exhaust assembly, minimizing any impact on the vehicle's aesthetics.

[0029] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. It should also be understood that the terminology used in the embodiments of the present invention is for describing specific implementation schemes and not for limiting the scope of protection of the present invention. Test methods in the following embodiments that do not specify specific conditions are generally performed under conventional conditions or according to the conditions recommended by the respective manufacturers.

[0030] Please see Figures 1 to 11It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0031] Please see Figure 1-3 This invention provides an in-vehicle biochemical system, comprising: an automotive air conditioning unit 1, the automotive air conditioning unit 1 including a plurality of air outlets 11; a concealed air duct mechanism 2, the concealed air duct mechanism 2 including: an air inlet pipe 21 and an exhaust assembly 22, the air inlet pipe 21 being connected to the interior of the vehicle and embedded in the lintel 200 along the length of the lintel 200 of the door 100, the exhaust assembly 22 being embedded in the B-pillar 300 of the door 100, one end of the air inlet pipe 21 being connected to the exhaust assembly 22, the exhaust assembly 22 being connected to the exterior of the vehicle; and a controller 3, the controller 3 being electrically connected to the exhaust assembly 22 and the automotive air conditioning unit 1 respectively, to control the air outlets 11 of the automotive air conditioning unit 1 in the in-vehicle biochemical mode to be arranged in a direction that guides the air inside the vehicle to the air inlet pipe 21, and to control the opening of the exhaust assembly 22 to generate negative pressure in the air inlet pipe 21 to draw and guide the air and exhaust the guided air to the exterior of the vehicle through the exhaust assembly 22.

[0032] In one embodiment of the present invention, during the in-vehicle air circulation process, when a designated seat requires directional airflow to refresh the in-vehicle air, the controller 3 activates the exhaust assembly 22 simultaneously, causing the vehicle air conditioning unit 1 to operate concurrently. This ensures that the air outlets 11 of the vehicle air conditioning unit 1 uniformly direct airflow towards the intake ducts 21 corresponding to the seats requiring air exchange, and adjusts the airflow parameters of the outlets 11 to maintain optimal airflow throughout the vehicle, uniformly delivering air to the corresponding intake ducts 21. The exhaust assembly 22 creates negative pressure along the length of the door lintel 200 in the intake ducts 21, absorbing the air from the outlets 11, and then directs the air through the intake ducts 21 to the exhaust assembly 22. The extracted air is then exhausted outside the vehicle via the exhaust assembly 22 installed on the B-pillar 300. This achieves directional airflow within the vehicle and efficient, directional air circulation, ensuring the comfort and safety of the occupants.

[0033] It should be noted that the B-pillar 300 is the main supporting structure of the door 100, also known as the center pillar, located between the front and rear doors. The B-pillar 300 is located on one side of the window glass 400 and connects to the door lintel 200. When the door 100 is closed, it is located in the central area of ​​the vehicle body. The B-pillar 300 includes the B-pillar 300 of the front door corresponding to the central area of ​​the vehicle body and the B-pillar 300 of the rear door corresponding to the central area of ​​the vehicle body.

[0034] like Figure 2-4 As shown, the exhaust assembly 22 includes: a high-speed vortex mechanism 221, which is vertically mounted on the B-pillar 300, with one side of the high-speed vortex mechanism 221 connected to the outside of the B-pillar 300; and a duct 222, with one end of the duct 222 connected to the top of the high-speed vortex mechanism 221 and the other end of the duct 222 connected to the air inlet duct 21.

[0035] In one embodiment of the present invention, when the exhaust assembly 22 is working, it generates vortex power through the high-speed vortex mechanism 221, and creates negative pressure suction on the air inlet pipe 21 through the air duct 222, so as to realize the air extraction port 23 to draw the air sent from the air outlet 11.

[0036] like Figure 3 As shown, the lower end of the high-speed vortex mechanism 221 is connected to a wiring harness 4. The wiring harness 4 extends vertically along the B-pillar 300 to the lower half of the door 100. The controller 3 is installed in the lower half of the door 100, and one end of the wiring harness 4 located in the lower half of the door 100 is electrically connected to the controller 3.

[0037] In one embodiment of the present invention, by arranging the wiring harness 4 along the B-pillar 300 to the controller 3 in the lower half of the door 100, a reasonable arrangement of the wiring harness 4 and the controller 3 is achieved, resulting in a more compact wiring connection structure. The controller 3 is a biochemical mode controller.

[0038] like Figure 4 As shown, one end of the air inlet pipe 21 opposite to the exhaust assembly 22 is a closed structure, and the air inlet pipe 21 is provided with an exhaust port 23 that communicates with the interior of the vehicle along its length. This is to achieve a uniform negative pressure suction force along the length of the air inlet pipe 21 when the exhaust assembly 22 is working, so as to draw the directional airflow outside the vehicle.

[0039] like Figure 4-6 As shown, the exhaust vent 23 is located inside the window glass 400 of the door 100. On the cross-section of the air intake pipe 21, the exhaust vent 23 and the air intake pipe 21 form a "ρ" shaped air intake channel 24.

[0040] In one embodiment of the present invention, by arranging the air inlet duct 21 and the exhaust port 23 on the lintel 200, a concealed design of the air inlet duct 21 within the lintel 200 is achieved. Furthermore, by arranging the exhaust port 23 along the length of the lintel 200 inside the window glass 400, the special structural design of the lintel 200 maximizes air extraction. When the exhaust assembly 22 generates negative pressure suction on the air inlet duct 21, the "ρ"-shaped air inlet duct 24 reduces the unit suction area of ​​the exhaust port 23, thereby enhancing the negative pressure suction. Moreover, the sucked-in air can quickly enter the exhaust assembly 22 through the air inlet duct 21 and be discharged externally.

[0041] like Figure 7-9 As shown, the high-speed vortex mechanism 221 includes: a turbo fan box 2211, with turbo fan channels 22111 penetrating through the upper and lower sides of the turbo fan box 2211, and an exhaust port 22112 connected to the turbo fan channels 22111 on one side of the turbo fan box 2211; and a vortex fan 2212, which is inserted into the turbo fan channels 22111 from bottom to top.

[0042] In one embodiment of the present invention, when the high-speed vortex mechanism 221 generates vortex wind force, it is formed by the high-speed rotation of the vortex fan 2212 within the vortex channel 22111 of the vortex wind direction 2211, and the force is discharged to the outside of the vehicle through an exhaust port 22112 connected to one side of the vortex channel 22111. It is worth noting that the exhaust port 22112 is located on the B-pillar 300 and is connected to the outside of the vehicle.

[0043] The vortex fan 2212 includes: a high-speed motor 22121, which is installed at the bottom of the vortex fan box 2211 corresponding to the vortex fan channel 22111; a fan bearing 22122, which is installed at the top of the vortex fan box 2211 corresponding to the vortex fan channel 22111; and a fan 22123, the upper end of which is connected to the fan bearing 22122, and the lower end of which is connected to the power output end of the high-speed motor 22121.

[0044] In one embodiment of the present invention, when the vortex fan 2212 is working, the high-speed motor 22121 drives the fan 22123 in the vortex fan channel 22111 to rotate, generating a negative pressure on the air inlet pipe 21, thereby achieving a negative pressure suction force at the exhaust port 23. Furthermore, the fan bearing 22122 can position the top side of the fan 22123 when it rotates at high speed.

[0045] like Figure 9As shown, the fan 22123 includes: a fan shaft 221231; and blades 221232, which are spirally mounted on the fan shaft 221231.

[0046] In one embodiment of the present invention, by utilizing the high-speed rotation of blades 221232 spirally mounted on the fan shaft 221231 to form a negative pressure suction, the absorbed air is discharged outside the vehicle through the exhaust port 22112.

[0047] like Figure 9 and 10 As shown, the fan bearing 22122 includes: a shaft housing 221221; a central shaft 221222, which is located in the middle of the shaft housing 221221; and a connecting plate 221223, one side of several sets of connecting plates 221223 is mounted on the central shaft 221222 along the circumferential direction of the central shaft 221222, and the other end of the connecting plate 221223 is connected to the inner wall of the shaft housing 221221.

[0048] In one embodiment of the present invention, when the blades 221232 rotate at high speed to form a suction force, the air drawn into the air duct 222 through the exhaust port 23 will enter the turbofan channel 22111 through the spaced channel between the connecting plates 221223, and the air will be further discharged outside the vehicle through the exhaust port 22112 by the exhaust action of the blades 221232.

[0049] like Figure 11 As shown, the controller 3 includes: an instruction acquisition unit 10, which acquires the start instruction for the corresponding seat information; an air vent adjustment unit 20, which confirms the seat information corresponding to the start instruction, controls the air outlet 11 of the car air conditioning unit 1 to be arranged in the guiding direction of the air vent 23 at the door lintel 200 of the door 100 corresponding to the corresponding seat information, and controls the air outlet parameters of the air vent 23, wherein the air outlet 11 is an electronic air outlet; and an air extraction control unit 30, which controls the start of the high-speed vortex mechanism 221 corresponding to the seat information, so that the corresponding air vent 23 generates negative pressure to draw in the air inside the car guided by the air outlet 11, and exhausts the air outside the car through the B-pillar 300.

[0050] In one embodiment of the present invention, during the control of the in-vehicle biochemical system, when it is necessary to activate the air circulation of a certain seat, the air circulation of the corresponding seat is activated by an external hardware switch or through human-computer interaction methods such as central control or voice commands. The command acquisition module 10 acquires the activation command. According to the activation command, the air outlet adjustment unit 20 controls the scheduling of the air outlets 11 of the car air conditioning device 1, so that the air supply direction of the air outlets 11 is adjusted to the exhaust vent 23 at the door lintel 200 corresponding to the designated seat, and the air supply parameters of the exhaust vent 23 are adjusted to uniformly direct the air in the vehicle towards the corresponding exhaust vent 23. At the same time, the ventilation control unit 30 controls the activation of the high-speed vortex mechanism 221, so that the high-speed motor 22121 drives the fan 22123 to rotate at high speed, forming a negative pressure on the ventilation vent 23 at the door frame 200, thereby generating a suction force at the ventilation vent 23, which draws in the air from the vehicle through the air outlet 11 and exhausts it outside the vehicle through the exhaust vent 22112 on the turbine fan box 2211 at the B-pillar, so as to generate a directional airflow field inside the vehicle. This airflow field will cover the isolation target, thereby achieving the air isolation effect for the designated occupants inside the vehicle.

[0051] It is worth noting that this invention achieves an in-vehicle biochemical isolation mode through an innovatively designed air circulation method. By directing the airflow inside the vehicle, the directional airflow field covers the pollution source, guiding the pollutants such as droplets, particles, and odors emitted from the pollution source out of the vehicle. This achieves an in-vehicle biochemical isolation effect for passengers without opening the windows, providing protection and comfort. Therefore, this system is named the in-vehicle biochemical mode.

[0052] In summary, this invention controls the air outlets 11 of the car's air conditioning unit 1 to direct airflow towards the exhaust vents 23 at the corresponding seat lintels 200 based on the activation command for air circulation scheduling of designated seats in the parking space. Furthermore, by controlling the exhaust assembly 22 to create negative pressure on the air inlet pipes 21 at the lintels 200, and then generating suction through the exhaust vents 23 located inside the window glass 400, the air inside the vehicle guided by the air outlets 11 is drawn out through the exhaust vents 22112 at the B-pillar where the exhaust assembly 22 is installed. This achieves a directional airflow and circulation within the vehicle, covering the target occupants within this flow field. At this time, odors, germs, and particulate matter from the target occupants will be isolated from other occupants by the flow field and discharged outside the vehicle, thus achieving biochemical isolation. Moreover, it prevents the occupants from being affected by other passing personnel, such as those smoking, eating (with pungent odors), the odor of infant feces, body odor, and other odors that could negatively impact their comfort. This system protects vehicle occupants from infectious diseases transmitted by other passengers within the cabin, especially those spread through droplets. Furthermore, it operates even with sealed windows, achieving efficient cabin air circulation at high speeds without impacting vehicle fuel consumption, NVH (noise, vibration, and harshness) performance. By arranging the air intake duct 21 and exhaust vent 23 along the length of the door lintel 200 and forming a "ρ"-shaped air intake duct 24, a concealed design for the air intake duct 21 and exhaust vent 23 is achieved, maximizing the suction range for designated seats. Moreover, the air duct structure formed by the air intake duct 21 and exhaust vent 23 is hidden within the A-pillar door frame, without incurring additional aesthetic costs. By installing the exhaust assembly 22 on the B-pillar 300, while ensuring external air intake, the system is integrated into the vehicle door through the specially designed installation of the air intake duct 21 and exhaust assembly 22, minimizing any aesthetic impact on the vehicle. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
