Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, specifically to a vehicle ventilation method, device, equipment, and storage medium. Background Technology

[0002] Motorhomes, often called "homes on wheels," combine the functions of a house and a vehicle, making them a favorite among travel enthusiasts. When a motorhome enters sleep mode, the windows are usually kept closed to ensure a stable interior temperature and enhance safety. In this mode, the motorhome typically relies on battery power to maintain the air conditioning and ventilation systems. If the battery runs out and the system automatically shuts down, air circulation inside the cabin will cease, potentially leading to insufficient oxygen or carbon dioxide buildup, thus posing a risk of suffocation. Summary of the Invention

[0024] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0025] Figure 1 A flowchart illustrating a first embodiment of the vehicle ventilation method of the present invention is shown, which can be executed by a domain controller in the vehicle, such as a body domain controller. Figure 1 As shown, the method includes the following steps:

[0026] Step 110: In response to the automatic exit from sleep mode event, control the ventilation device to open to achieve air circulation between the vehicle interior and the external environment. The automatic exit from sleep mode event is the situation where the vehicle automatically exits sleep mode based on preset conditions without human intervention.

[0027] The vehicle can be a motorhome. In sleep mode, the vehicle enters a low-power state, shutting down or reducing the power consumption of non-essential equipment, such as the entertainment system and most lighting, to extend battery life. The air conditioning and ventilation systems typically remain operational to ensure comfortable temperature and air quality inside the vehicle. This is especially important for passengers spending the night in the vehicle.

[0028] The automatic exit from sleep mode event is a trigger condition that refers to the vehicle automatically exiting sleep mode based on preset conditions without human intervention. These conditions may include the battery level dropping to a certain threshold, changes in the vehicle's interior temperature, or changes in other environmental factors.

[0029] Once an event triggering the automatic exit from sleep mode is detected, the ventilation system automatically activates. The purpose of activating the ventilation system is to allow air circulation between the vehicle's interior and the external environment. This replenishes oxygen inside the vehicle and removes carbon dioxide and other potentially accumulated gases, ensuring good air quality and passenger safety.

[0030] In one alternative approach, the automatic exit from sleep mode event includes a low battery exit from sleep mode event. In response to the automatic exit from sleep mode event, the ventilation device is controlled to open, which may specifically include the following steps:

[0031] In response to a low battery exit sleep mode event, the ventilation device is opened. The low battery exit sleep mode event is triggered when the battery level is detected to be lower than a preset battery level threshold, which causes the vehicle to exit sleep mode.

[0032] The low battery exit sleep mode event is a specific type of automatic exit sleep mode event, referring to the situation where the vehicle automatically exits sleep mode when the battery level drops below a preset threshold. Once a low battery exit sleep mode event is detected, the ventilator automatically activates.

[0033] This invention enables air circulation between the vehicle's interior and the external environment by controlling the opening of a ventilation device upon detecting an automatic exit from sleep mode. This automated response mechanism ensures that air circulation is promptly restored after the vehicle exits sleep mode due to insufficient battery power or other reasons. This method significantly improves vehicle safety in sleep mode, preventing health risks caused by interrupted air circulation.

[0034] Figure 2 A flowchart of another embodiment of the vehicle ventilation method of the present invention is shown, which can be executed by a domain controller in the vehicle. Figure 2 As shown, the method includes the following steps:

[0035] Step 210: In response to the automatic exit from sleep mode event, the control sends a first pulse signal to the electromagnetic lock to open the ventilation device. The electromagnetic lock is used to momentarily de-energize upon receiving the first pulse signal, releasing its locking state to the spring. The spring is used to release its elastic force to push the ventilation device open when the electromagnetic lock is de-energized.

[0036] A pulse signal is an electrical signal, but it typically consumes less power than a continuous electrical signal. This is because a pulse signal transmits current for a specific, short period of time, rather than continuously consuming electrical energy.

[0037] In this embodiment of the invention, in response to an automatic exit from sleep mode event, a pulse signal (referred to here as the first pulse signal for ease of distinction) is sent to the electromagnetic lock. Upon receiving the pulse signal, the electromagnetic lock immediately de-energizes, thereby releasing its locking state to the spring. With the electromagnetic lock de-energized, the previously locked spring releases its stored elastic force. At this time, the spring force pushes the vent cover in the venting device to open, enabling air circulation between the vehicle interior and the external environment.

[0038] This design utilizes the low power consumption of pulse signals and the energy storage capacity of mechanical springs to achieve automatic opening of the ventilation device in a highly efficient and energy-saving manner.

[0039] In one alternative embodiment, the vehicle ventilation method of the present invention may further include the following steps:

[0040] When the ventilator is in the open state, if the vehicle speed is detected to meet the preset speed condition, the control sends a second pulse signal to the electromagnetic lock to close the ventilator. The electromagnetic lock is used to be energized instantaneously after receiving the second pulse signal to release its locking state to the gear. The gear is used to engage with the rack to close the ventilator when the electromagnetic lock is energized.

[0041] In this embodiment, when the vent is open, if the vehicle speed exceeds a preset speed threshold, a pulse signal (referred to here as the second pulse signal) is sent to the electromagnetic lock. Upon receiving this pulse signal, the electromagnetic lock is immediately energized. This energization activates the gear drive mechanism, allowing it to operate. The gear, through engagement with the rack, gradually closes the vent cover. The gear-driven rack movement ensures a smooth closure of the vent cover, thus maintaining aerodynamic stability and safety within the vehicle at high speeds. This mechanism ensures the automatic closing function of the vent under specific conditions to adapt to dynamic changes in the vehicle.

[0042] In one alternative embodiment, the vehicle includes a mechanical knob, in which a gear engages with a rack to open the ventilator when the user rotates the mechanical knob in a first direction, and to close the ventilator when the user rotates the mechanical knob in a second direction.

[0043] In this embodiment, a mechanical knob is installed on the vehicle, which the user can rotate to control the ventilator. When the user rotates the mechanical knob in a first direction, the gear and rack mesh and move the rack, thereby opening the ventilator. This action opens the vent cover, allowing air to circulate between the inside and outside of the vehicle. Conversely, when the user rotates the mechanical knob in a second direction, the gear and rack mesh again, but this time moving the rack in the opposite direction, thereby closing the ventilator. This closes the vent cover, preventing air circulation between the inside and outside of the vehicle. This design allows the user to manually control the opening and closing of the vent cover through simple mechanical operation, without relying on electrical or automated systems. This provides a reliable backup operation method in certain situations (such as insufficient power or system failure).

[0044] In one alternative approach, when the venting device is in the open state, the angle between the vent cover in the venting device and the vehicle body meets a preset angle condition, so as to guide the water flow down the cover surface and prevent water from entering the vehicle.

[0045] In this embodiment, the angle between the vent cover and the vehicle body is designed to meet a specific preset angle so that when the vent is opened, the preset angle allows water to flow naturally down the surface of the cover without entering the vehicle. This design takes into account the flow characteristics of rainwater or other liquids, ensuring that water is guided to the outside of the vehicle.

[0046] In one alternative approach, a hydrophobic and breathable membrane is placed over the vent holes of the breathable device.

[0047] In one alternative approach, the ventilation device also includes air passing through a grille.

[0048] Air enters through the grille, then passes through the hydrophobic and breathable membrane, and finally flows into the vehicle compartment. The ventilation device of this invention can achieve an airflow rate of 12 liters per second or more to provide sufficient ventilation. The hydrophobic and breathable membrane covering the ventilation holes has a dual function. First, it allows air to pass freely, ensuring ventilation and air exchange within the vehicle. Second, its hydrophobicity effectively blocks moisture, preventing rainwater or other liquids from entering the vehicle compartment through the ventilation holes.

[0049] Reference Figure 3 The diagram shown is a structural schematic of the ventilation device and its control system provided by the present invention, including a gear 1, an electromagnetic signal line 2, an electromagnetic lock body 3, an electromagnetic lock magnet 4, a spring 5, an air grille 6, a vehicle body shell 7, a ventilation cover 8, a mechanical knob 9, and a rack 10. This system uses the cooperation of the gear and rack to control the opening and closing of the ventilation cover. The electromagnetic lock and electromagnetic signal line provide electronic control functions, while the spring and mechanical knob provide the possibility of mechanical operation. The air grille ensures the quality of airflow.

[0050] Reference Figure 4 The diagram shows a flowchart of the vehicle ventilation method provided by this invention. This flowchart describes the operation of the vehicle's electromagnetic lock and gear drive under different vehicle speeds and battery power conditions. The sleep mode of a motorhome relies on battery power to maintain the operation of the air conditioning and ventilation systems. When insufficient power causes the system to automatically shut down, the enclosed cabin may pose a risk of suffocation due to insufficient oxygen or carbon dioxide accumulation. Furthermore, users typically open windows or sunroofs to maintain ventilation while sleeping. However, if the vehicle's "automatic window closing in rain" function is enabled, the automatic closing of windows in rainy weather may pose a suffocation risk; disabling this function may result in rainwater entering the vehicle. The vehicle ventilation method provided by this invention controls the opening of a ventilation device when the vehicle automatically exits sleep mode, enabling air circulation between the inside and outside of the vehicle. The ventilation device is equipped with a rainproof design to prevent rainwater from entering the vehicle, thereby solving the above two safety hazards.

[0051] In one alternative approach, the vehicle includes multiple ventilation devices.

[0052] In this embodiment, multiple ventilation devices can be installed in the vehicle and distributed in different positions in the passenger compartment. Each ventilation device is controlled independently, so even if one of them fails, it will not significantly affect the overall ventilation efficiency.

[0053] This invention enables air circulation between the vehicle's interior and the external environment by controlling the opening of a ventilation device upon detecting an automatic exit from sleep mode. This automated response mechanism ensures that air circulation is promptly restored after the vehicle exits sleep mode due to insufficient battery power or other reasons. This method significantly improves vehicle safety in sleep mode, preventing health risks caused by interrupted air circulation.

[0054] Figure 5 A schematic diagram of an embodiment of the vehicle ventilation device of the present invention is shown. Figure 5 As shown, the device 500 includes a control module 510.

[0055] The control module is used to respond to the automatic exit from sleep mode event by controlling the opening of the ventilation device to achieve air circulation between the vehicle interior and the external environment. The automatic exit from sleep mode event is the situation where the vehicle automatically exits sleep mode based on preset conditions without human intervention.

[0056] In one alternative approach, the automatic exit from sleep mode event includes a low battery exit from sleep mode event, and the control module is specifically used for:

[0057] In response to a low battery exit sleep mode event, the ventilation device is opened. The low battery exit sleep mode event is triggered when the battery level is detected to be lower than a preset battery level threshold, which causes the vehicle to exit sleep mode.

[0058] In one alternative approach, the control module is specifically used for:

[0059] In response to an automatic exit from sleep mode event, the control sends a first pulse signal to the electromagnetic lock to open the ventilation device. The electromagnetic lock is used to momentarily de-energize upon receiving the first pulse signal, releasing its locking state to the spring. The spring is used to release its elastic force to push the ventilation device open when the electromagnetic lock is de-energized.

[0060] In one alternative embodiment, the vehicle ventilation device of the present invention is further used for:

[0061] When the ventilator is in the open state, if the vehicle speed is detected to meet the preset speed condition, the control sends a second pulse signal to the electromagnetic lock to close the ventilator. The electromagnetic lock is used to be energized instantaneously after receiving the second pulse signal to release its locking state to the gear. The gear is used to engage with the rack to close the ventilator when the electromagnetic lock is energized.

[0062] In one alternative embodiment, the vehicle includes a mechanical knob, in which a gear engages with a rack to open the ventilator when the user rotates the mechanical knob in a first direction, and to close the ventilator when the user rotates the mechanical knob in a second direction.

[0063] In one alternative approach, when the venting device is in the open state, the angle between the vent cover in the venting device and the vehicle body meets a preset angle condition, so as to guide the water flow down the cover surface and prevent water from entering the vehicle.

[0064] In one alternative approach, a hydrophobic and breathable membrane is placed over the vent holes of the breathable device.

[0065] This invention enables air circulation between the vehicle's interior and the external environment by controlling the opening of a ventilation device upon detecting an automatic exit from sleep mode. This automated response mechanism ensures that air circulation is promptly restored after the vehicle exits sleep mode due to insufficient battery power or other reasons. This method significantly improves vehicle safety in sleep mode, preventing health risks caused by interrupted air circulation.
