Description

Technical Field

[0001] This invention relates to the field of vehicle intelligent technology, and more specifically, to an onboard canopy system and its control method. Background Technology

[0002] Carports serve as outdoor barriers to protect vehicles, primarily providing functions such as wind and rain protection, sun protection, landscaping enhancement, and protection against falling objects. Common carports are stationary protective structures; once the vehicle is outside the canopy, they cease to protect it.

[0003] As vehicle usage needs diversify, the scenarios in which vehicles operate are becoming increasingly complex. Examples include vehicles being exposed to direct sunlight in open-air parking spaces, vehicles being covered in snow in open parking lots making them difficult to move, and vehicles needing to purchase and deploy awnings separately while camping. Therefore, providing a vehicle-mounted canopy that offers protection for vehicles and occupants in outdoor environments is highly desirable.

[0004] In the prior art, a car passenger sunshade structure is provided, which includes a headliner with mounting holes for installing a sunshade device. The upper end of the sunshade device is a mounting plate fixed to the roof sheet metal, and the lower end is a decorative panel. The planar extension directions of the mounting plate and the decorative panel are parallel to each other and connected by a multi-link structure, allowing the distance between the decorative panel and the mounting plate to be adjustable. A soft blackout fabric connects the mounting plate and the decorative panel. This structure has the advantages of occupying less space, not obstructing the driver's view, having a more compact structure, and being more convenient to use. However, it only optimizes the passenger compartment sunshade structure and does not address climate-related whole-vehicle sunshade and rain / snow protection, nor does it consider the increasingly popular camping scenarios, thus its application scenarios are relatively limited.

[0005] Another type of car sunshade includes bases respectively located on the left and right sides of the car. Each base has a connecting device for securing it to the car, allowing it to be fixed on both sides. A support frame extends upwards from the base to the top of the car, and a canopy is mounted on top of the support frame to cover the car, thus blocking sunlight or rain and providing better protection. However, this solution is only a structural improvement and cannot be integrated with the vehicle. It is also relatively complex, inconvenient to install, requires manual installation and opening, and lacks automation. Summary of the Invention

[0006] This invention addresses the technical problems existing in the prior art by providing a vehicle canopy system and its control method. When not in use, it can be folded and hidden in the roof rack of the vehicle. It is easy to operate, highly practical, and can be linked to the weather, making it especially suitable for camping scenarios.

[0007] According to a first aspect of the present invention, a vehicle canopy system is provided, comprising a temperature acquisition unit, a light acquisition unit, an image acquisition unit, a control unit, and two sets of retractable canopies disposed on luggage racks on both sides of the vehicle roof and symmetrical about the vehicle's X-axis. Each set of retractable canopies includes an inner canopy and an outer canopy. The inner canopy can extend along the Y-axis toward the vehicle's centerline, and the outer canopy can extend along the Y-axis away from the vehicle's centerline.

[0008] The temperature acquisition unit is used to acquire the temperature signal of the vehicle;

[0009] The light acquisition unit is used to acquire light signals from the external environment of the vehicle;

[0010] The image acquisition unit is used to acquire image signals of the external environment of the vehicle;

[0011] The control unit is used to determine the type of environment in which the vehicle is located based on the collected temperature signal, light signal and image signal, and output the canopy control signal based on the determination result;

[0012] The retractable canopy is used to open or close the corresponding inner canopy and / or outer canopy according to the canopy control signal.

[0013] Based on the above technical solution, the present invention can also be improved as follows.

[0014] Optionally, the inner or outer canopy includes a first-level canopy that can extend and retract along the vehicle's Y-axis and a second-level canopy that can rotate and extend and retract about the vehicle's Z-axis, with adjacent sides of the first-level and second-level canopies connected.

[0015] Optionally, the first-stage canopy includes a first canopy, a rotating mechanism, and a traction mechanism. The first canopy is located in the middle section of the luggage rack and can be rolled up inside the luggage rack. One end of the first canopy extends out along the opening of the luggage rack and can extend and retract in the Y direction. A rotating mechanism is provided at each end of the luggage rack, and a traction mechanism is provided on each rotating mechanism. The rotating mechanism includes a rotating shaft, a rotating motor, and a first guide rod. The rotating shaft is located at the end of the luggage rack in the Z direction. One end of the first guide rod is sleeved on the outer circumference of the rotating shaft and has a clearance fit with the rotating shaft. The output end of the rotating motor is connected to... One end of the first guide rod connected to the rotating shaft is driven to rotate the first guide rod around the rotating shaft; the traction mechanism includes a traction line, a drive wheel, a driven wheel, and a traction motor. The drive wheel is located on one end of the first guide rod connected to the rotating shaft, and the driven wheel is located on the other end of the first guide rod. The traction line is sleeved on the outer circumference of the drive wheel and the driven wheel and is driven to the drive wheel. The traction motor is driven to the drive wheel and is used to drive the drive wheel to rotate; one retractable end of the first tarpaulin is fixedly connected to a point on the traction line through a connector.

[0016] Optionally, the second-level canopy includes a second canopy and a second guide rod. One end of the second guide rod is coaxially sleeved on the rotating shaft along the Z-direction with the first guide rod, and the end of the second guide rod connected to the rotating shaft is in transmission engagement with the output end of the rotary motor. The second canopy is fan-shaped, with one side of the fan fixedly connected to the first guide rod and the other side of the fan fixedly connected to the second guide rod. The rotary motor is a rotary telescopic motor, whose output end synchronously extends and retracts axially during rotation. When controlling the state of the first canopy, the output end of the rotary motor synchronously engages with the first and second guide rods. When controlling the state of the second canopy, the output end of the rotary motor disengages from the first guide rod and only engages with the second guide rod.

[0017] Optionally, the first tarpaulin and / or the second tarpaulin are provided with a heating unit, which is signal-connected to the control unit and used to heat the first tarpaulin and / or the second tarpaulin.

[0018] Optionally, the first tarpaulin and / or the second tarpaulin are provided with a solar film, which is signal-connected to the control unit and used to power the system by converting solar energy into electrical energy.

[0019] According to a second aspect of the present invention, based on the above-described vehicle canopy system, a vehicle canopy control method is also provided, comprising:

[0020] Acquire vehicle status signals and temperature signals, as well as light intensity signals and image signals of the external environment;

[0021] The vehicle status signal determines the vehicle mode and whether it is parked; the temperature and light intensity signals determine whether the vehicle is in a sun-exposed environment; and the image signal determines whether the vehicle is in a rainy / snowy environment.

[0022] In sunshade / snow protection mode, if the vehicle is determined to be parked and is in a sunny or snowy environment, the inner canopy of the retractable roof will be opened.

[0023] In camping mode, if the vehicle is determined to be parked and is in a sunny or rainy / snowy environment, the inner and / or outer canopy of the retractable awning will be opened.

[0024] Optionally, determining whether a vehicle is in a sun-exposed environment based on temperature and light intensity signals includes:

[0025] The temperature signal is compared with a high temperature threshold, and the light intensity signal is compared with a light intensity threshold. If the real-time temperature is greater than the high temperature threshold and the real-time light intensity is greater than the first light intensity threshold, then the vehicle is determined to be in a sun-exposed environment.

[0026] Optionally, in camping mode, the following features are also included:

[0027] If, based on the light intensity signals distributed on both sides of the vehicle along the Y direction, it is determined that there is a sun shadow under the vehicle on either side, and the measured real-time temperature is within the medium temperature range, then the inner canopy of the retractable canopy is controlled to retract.

[0028] Calculate the angle h between the incident direction of sunlight and the ground plane based on the solar declination, the geographical latitude of the campsite, and the hour angle;

[0029] Obtain the vehicle height H1, measure the distance L1 between the person and the vehicle and the real-time height H2 of the camper's head above the ground based on image signals and / or radar signals, and calculate the angle α between the sunlight and the ground plane when the camper is between the light and shadow thresholds based on the vehicle height H1, the distance L1 between the person and the vehicle and the real-time height H2 of the camper's head above the ground.

[0030] Compare the included angle α with the included angle h. If α < h and the measured real-time temperature is within the medium temperature range, then control the retractable canopy to retract.

[0031] Optionally, the angle α between sunlight and the ground plane when the camper is between the light and shadow thresholds can be calculated using the following formula:

[0032]

[0033] According to a third aspect of the present invention, an electronic device is provided, including a memory and a processor, wherein the processor is configured to implement the steps of the aforementioned vehicle canopy control method when executing a computer management program stored in the memory.

[0034] According to a fourth aspect of the present invention, a computer-readable storage medium is provided, on which a computer management class program is stored, wherein the computer management class program, when executed by a processor, implements the steps of the aforementioned vehicle canopy control method.

[0035] This invention provides a vehicle-mounted canopy system, control method, electronic device, and storage medium. The retractable canopy is hidden in the roof rack, which is aesthetically pleasing and does not affect the functionality of the roof rack. The opening and closing control of the retractable canopy is linked to the weather, and the retractable canopy can be automatically controlled according to the real-time weather to achieve sunshade and / or snow protection functions. No manual support or storage of the canopy is required, and the control is simple. It is especially suitable for camping scenarios, enhancing the functionality and fun of the vehicle.

[0048] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0049] Figure 1 This invention provides a block diagram of a vehicle-mounted canopy system. First, it should be noted that the X, Y, and Z axes mentioned in this invention are based on the vehicle coordinate system. For example... Figure 1 As shown, this embodiment of the invention provides a vehicle canopy system, which includes a temperature acquisition unit, a light acquisition unit, an image acquisition unit, a control unit, and two sets of retractable canopies 2 mounted on the roof racks 1 on both sides of the vehicle and symmetrical about the vehicle's X-axis. Each set of retractable canopies 2 includes an inner canopy 2A and an outer canopy 2B. The inner canopy 2A can extend along the Y-axis toward the vehicle's centerline, and the outer canopy 2B can extend along the Y-axis away from the vehicle's centerline.

[0050] The temperature acquisition unit can use temperature sensors distributed inside and outside the vehicle to collect the vehicle's temperature signal;

[0051] The light acquisition unit can be a light intensity sensor distributed on both sides of the vehicle to collect light signals from the external environment.

[0052] The image acquisition unit may employ a camera and / or radar sensor to acquire image signals of the external environment of the vehicle.

[0053] The control unit can be a vehicle-mounted system and / or a mobile phone, used to determine the type of environment in which the vehicle is located based on the collected temperature signal, light signal and image signal, and output the canopy control signal based on the determination result;

[0054] The retractable canopy 2 is used to open or close the corresponding inner canopy 2A and / or outer canopy 2B according to the canopy control signal.

[0055] It is understandable that, based on the deficiencies in the background technology, this embodiment of the invention proposes a vehicle-mounted canopy system. Figure 2 (a) is a schematic diagram of all retractable canopies 2 in the closed state. In the closed state, the retractable canopies 2 on the left and right sides of the vehicle are retracted onto the luggage rack 1. Figure 2(b) Taking the retractable canopy 2 on the left roof rack 101 as an example, the system demonstrates the retractable canopy 2 in its fully open state. This system features foldable and retractable canopies 2 mounted on the left and right roof racks 101 and 102, respectively, symmetrically arranged on the left and right sides of the vehicle roof. The control of the retractable canopy 2 is linked to the vehicle's environment. Based on real-time environmental information, the system controls the retractable canopy 2; for example, in direct sunlight, the inner canopy 2A can be opened to provide shade, and in snowy weather, the inner canopy 2A and / or the outer canopy 2B can be opened to protect the vehicle from snow. This system is suitable for both general parking and camping modes, and the combination of the inner canopy 2A and the outer canopy 2B makes the vehicle suitable for a wider range of scenarios.

[0056] In this embodiment, the retractable canopy 2 is hidden in the roof rack, which is aesthetically pleasing and does not affect the function of the roof rack. The opening and closing control of the retractable canopy 2 is linked to the weather, and the retractable canopy 2 can be automatically controlled according to the real-time weather to achieve sunshade and / or snow protection functions without the need for manual support or storage of the canopy, making the control simple. It is especially suitable for camping scenarios, enhancing the functionality and fun of the vehicle.

[0057] In one possible embodiment, the inner canopy 2A or the outer canopy 2B includes a first-level canopy that is retractable along the Y-axis of the vehicle and a second-level canopy that is rotatable and retractable about the Z-axis of the vehicle, with adjacent sides of the first-level canopy and the second-level canopy connected.

[0058] It is understandable that, such as Figure 3 The diagram illustrates the opening steps of the inner canopy 2A and outer canopy 2B on a retractable roof 2 on a luggage rack 1 (e.g., the left luggage rack 101). The opening steps for the inner canopy 2A and outer canopy 2B are identical; either one can be opened, or both can be opened simultaneously. This embodiment uses the opening process of the retractable roof 2 on the left luggage rack 101 as an example. Figure 3 (a) A preparatory step before opening the first-level canopy, namely, rotating the folded support structure from its folded state to make it sufficient to support the opening of the first-level canopy. Figure 3 (b) is a schematic diagram of the first-stage canopy being opened along the Y-direction of the vehicle. Figure 3 (c) Schematic diagram of the tarpaulin for rotating the support structure again to open the second-level canopy. Figure 3 (b) indicates that only the first-level canopy is open, which is the semi-open state of the retractable canopy 2. Figure 3 (c) is the state where the first and second level canopies are open. At this time, the retractable canopy 2 is fully open.

[0059] In one possible embodiment, combining Figures 4-6 As shown, the first-stage canopy includes a first canopy 21, a rotating mechanism 22, and a traction mechanism 23, as follows: Figure 6As shown, the first tarpaulin 21 is located in the middle section of the luggage rack 1 and can be rolled up inside the luggage rack 1 via a roller 211 or other storage mechanism. One end of the first tarpaulin 21 extends out along the opening of the luggage rack 1 and can extend and retract in the Y direction. A rotating mechanism 22 is provided at each end of the luggage rack 1, and a traction mechanism 23 is provided on each rotating mechanism 22. Figure 4 As shown, the rotating mechanism 22 includes a rotating shaft 221, a rotating motor 222, and a first guide rod 223. The rotating shaft 221 is disposed at the end of the luggage rack 1 along the Z direction. One end of the first guide rod 223 is sleeved on the outer circumference of the rotating shaft 221 and is clearance-fitted with the rotating shaft 221. The output end of the rotating motor 222 is in transmission cooperation with the end of the first guide rod 223 connected to the rotating shaft 221, and is used to drive the first guide rod 223 to rotate around the rotating shaft 221. More specifically, the output end of the rotating motor 222 is set as a drive gear shaft 2221 for outputting torque. A first driven gear 2231 is fixedly disposed on the outer circumference of the end of the first guide rod 223 connected to the rotating shaft 221. Through the meshing transmission between the drive gear shaft 2221 and the first driven gear 2231, the torque is output to the first guide rod 223, thereby driving the first guide rod 223 to rotate around the rotating shaft 221, so as to realize the rotation extension or folding of the first guide rod 223.

[0060] like Figure 6 As shown, the traction mechanism 23 includes a traction line 231, a driving wheel 232, a driven wheel 233, and a traction motor 234. The driving wheel 232 is mounted on the first guide rod 223 and connected to one end of the rotating shaft 221. The driven wheel 233 is mounted on the other end of the first guide rod 223. The traction line 231 is sleeved around the outer circumference of the driving wheel 232 and the driven wheel 233 and is in transmission cooperation with the driving wheel 232. The traction motor 234 is in transmission connection with the driving wheel 232 and is used to drive the driving wheel 232 to rotate. The retractable end of the first tarpaulin 21 is connected by a connector (e.g., Figure 6 The connecting block 235 shown is fixedly connected to a point on the traction line 231. When the traction motor 234 drives the drive wheel 232 to rotate, the drive wheel 232, the traction line 231, and the driven wheel 233 form a mechanism similar to a belt drive, driving the traction line 231 to rotate around the drive wheel 232. The traction mechanisms 23 on both sides of the first tarpaulin 21 cooperate with each other, thereby pulling the retractable end of the first tarpaulin 21 out from the roller 211 to open it, thus realizing the opening of the first-level canopy. In order to realize the automatic retraction of the first tarpaulin 21, the roller 211 can be set as a damping shaft 221, or it can be set as an automatic retraction roller 211 controlled by a roller motor.

[0061] In one possible embodiment, such as Figure 7The diagram shows the second-stage canopy in its unfolded state. The second-stage canopy includes a second canopy 24 and a second guide rod 224. One end of the second guide rod 224 is coaxially mounted on the rotating shaft 221 along the Z-axis with the first guide rod 223. The end of the second guide rod 224 connected to the rotating shaft 221 is connected to the output end of the rotary motor 222. For example, a second driven gear 2241 is fixedly mounted on the end of the second guide rod 224 connected to the rotating shaft 221. The second driven gear 2241 meshes with the driving gear shaft 2221 at the output end of the rotary motor 222, transmitting torque to the second guide rod 224, thereby driving the second guide rod 224 to rotate around the rotating shaft 221. The second guide rod 224 can be rotated out or folded; the second tarpaulin 24 is fan-shaped, one side of the fan is fixedly connected to the first guide rod 223, and the other side of the fan is fixedly connected to the second guide rod 224; the rotary motor 222 is a rotary telescopic motor, and its output end synchronously extends and retracts axially during rotation. When controlling the state of the first tarpaulin 21, the output end of the rotary motor 222 synchronously drives and cooperates with the first guide rod 223 and the second guide rod 224. When controlling the state of the second tarpaulin 24, the output end of the rotary motor 222 is disengaged from the first guide rod 223 and only drives and cooperates with the second guide rod 224.

[0062] Understandably, the second-level canopy has a structure resembling a folding fan, with the first guide rod 223 and the second guide rod 224 hinged together via a pivot 221. Figure 4 As shown, when the first guide rod 223 overlaps with the second guide rod 224, the second tarpaulin 24 is folded, as... Figure 7 As shown, when the second guide rod 224 rotates open relative to the first guide rod 223 and reaches the limit position of the second tarpaulin 24, the second tarpaulin 24 is in a fully open state. In this embodiment, the rotary motor 222 is a rotary telescopic motor, meaning its output end can synchronously extend and retract axially during rotation. Figure 5 The diagram shows the principle of rotary motor 222 driving the first guide rod 223 and the second guide rod 224. Figure 5 (a) is a schematic diagram of the principle that the rotating shaft 221 simultaneously drives the first guide rod 223 and the second guide rod 224. Figure 5(b) is a schematic diagram illustrating the principle of the rotating shaft 221 driving only the second guide rod 224. For example, when controlling the state of the first tarpaulin 21, the output end of the rotary motor 222 synchronously engages with the first guide rod 223 and the second guide rod 224. During this process, the drive gear shaft 2221 at the output end of the rotary motor 222 rotates while simultaneously moving axially. When controlling the state of the second tarpaulin 24, the drive gear shaft 2221 at the output end of the rotary motor 222, due to its axial movement in the previous stage, has disengaged from the first driven gear 2231 at the end of the first guide rod 223 and only engages with the second driven gear 2241 at the end of the second guide rod 224, thus achieving meshing transmission only on the second guide rod 224 during the opening stage of the second tarpaulin 24. It can be understood that when the retractable awning 2 retracts, the steps are the opposite of the steps when the retractable awning 2 opens, and the driving direction and driving sequence of the rotary motor 222 for the first guide rod 223 and the second guide rod 224 are also opposite.

[0063] In one possible embodiment, the first tarpaulin 21 and / or the second tarpaulin 24 are provided with a heating unit, which is signal-connected to a control unit for heating the first tarpaulin 21 and / or the second tarpaulin 24.

[0064] Understandably, when the control unit determines that the current weather is snowy based on various detection signals, it can energize the heating unit inside the tarpaulin, such as the heating wire, to generate heat to melt the snow that has fallen onto the tarpaulin and prevent the snow from accumulating too much and collapsing the retractable tarpaulin 2.

[0065] In one possible embodiment, the first tarpaulin 21 and / or the second tarpaulin 24 are provided with a solar film, which is signal-connected to the control unit for powering the system by converting solar energy into electrical energy.

[0066] Understandably, solar film can charge the vehicle battery when the roof is open, especially in camping mode, absorbing solar energy for storage, supplementing the vehicle's energy consumption, and powering camping equipment.

[0067] Based on the vehicle canopy system provided in the foregoing embodiments, for example Figure 8 As shown in the flowchart, this embodiment also provides a vehicle canopy control method, including:

[0068] Acquire vehicle status signals and temperature signals, as well as light intensity signals and image signals of the external environment;

[0069] The vehicle status signals determine the vehicle mode and whether it is parked; the temperature and light intensity signals determine whether the vehicle is in a sun-exposed environment; and the image signals are used for image recognition to determine whether the vehicle is in a rainy / snowy environment.

[0070] Specifically, determining whether someone is in a state of intense sunlight exposure includes:

[0071] Set a high temperature threshold (e.g.) Figure 8 If the real-time temperature is greater than the high temperature threshold and the real-time light intensity is greater than the first light intensity threshold, then the vehicle is determined to be in a sun-exposed environment.

[0072] In sunshade / snow protection mode, if the vehicle is determined to be parked and is in a sunny or snowy environment, the inner canopy 2A of the retractable canopy 2 will be opened to provide sunshade or snow protection.

[0073] In camping mode, if the vehicle is determined to be parked and is in a sunny or rainy / snowy environment, the inner canopy 2A and / or outer canopy 2B of the retractable canopy 2 will be opened.

[0074] Understandably, the control mode of the retractable canopy 2 can be selected by the operator via the vehicle's infotainment screen or mobile app. Whether in sunshade / snow protection mode or camping mode, opening the inner canopy 2A or outer canopy 2B requires the vehicle to be parked. When the temperature rises to a certain level or in rainy or snowy weather, the screen and mobile app will notify the operator that the canopy can be opened. It can be controlled via the in-vehicle button switch or the mobile app. During operation, all four canopies on both sides of the vehicle (two inner canopies 2A and two outer canopies 2B) can be opened with a single button press. Alternatively, the sunshade / snow protection mode can be opened individually (opening the two inner canopies 2A), the camping mode can be opened individually (opening the two outer canopies 2B), or any designated canopy can be opened individually.

[0075] In one possible embodiment, in camping mode, it further includes:

[0076] If, based on the light intensity signals distributed on both sides of the vehicle along the Y direction, it is determined that there is a sun shadow on either side of the vehicle, and the measured real-time temperature is within the medium temperature range, then the inner canopy 2A of the retractable canopy 2 is controlled to retract. Specifically, when determining whether one side of the vehicle has a sun shadow, the light intensity signals on both sides of the vehicle can be compared. If the difference between the light intensity signals on both sides of the vehicle is greater than a set value, then it is determined that the side with weaker light intensity has a sun shadow.

[0077] Based on the solar declination δ and the geographical latitude of the campsite The angle h between the incident direction of sunlight and the ground plane is calculated using the hour angle t. Specifically, the formula for calculating the angle h is:

[0078]

[0079] Among them, the solar declination δ and the geographical latitude of the campsite This can be obtained through high-precision maps and vehicle-mounted systems; the time angle t is the local time of the campsite.

[0080] Obtain the vehicle height H1, measure the distance L1 between the person and the vehicle and the real-time height H2 of the camper's head above the ground based on the image signal and / or radar signal, and calculate the angle α between the sunlight and the ground plane when the camper is between the light and shadow thresholds using the following formula based on the vehicle height H1, the distance L1 between the person and the vehicle and the real-time height H2 of the camper's head above the ground.

[0081]

[0082] Compare the included angle α with the included angle h. If α < h and the measured real-time temperature is within the medium temperature range, then control the outer canopy 2B of the telescopic canopy 2 to retract.

[0083] It is understandable that the medium temperature range is a preset, relatively comfortable temperature. In this embodiment, when the temperature sensor detects that the temperature and lighting are suitable, the outer canopy 2B will automatically retract, providing a better physical and mental environment for camping. When the angle of the sunlight creates a shadow under the vehicle, the inner canopy 2A will automatically retract, eliminating the need for sunshade and allowing campers to better integrate with nature, thus enhancing the camping experience.
