[0002] Since the area of the vehicle roof is usually smaller than that of the chassis cabin, when the vehicle door is opened in rainy weather, the roof edge cannot cover the area after the door is opened, causing rainwater to directly drip on the seat edge, the rocker and the cabin, resulting in a wet seat and affecting the comfort of riding. When the user gets in or out of the vehicle, he or she will have the action of holding or folding an umbrella, and since the door is in an open state at this time, the user's body will be exposed to the rain for a short time, especially the experience of getting wet during the folding action. The current market has only the solution of adding a rain brow for the improvement of vehicle riding in rainy weather, but the rain brow can only cover the gap at the top of the window, and the main function is still for ventilation and air exchange when the window is slightly open in rainy weather.

[0042] The following specific examples illustrate the implementation of the present invention. Users 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. 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. Where there is no conflict, the following embodiments and features in the embodiments can be combined with each other.
[0043] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0044] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.
[0045] Please see Figures 1 to 6 The present invention provides a vehicle rainproof device 100 for installation at the door 201 of a vehicle 200, comprising: a roller 1, a rainproof film 2, and a drive component 3.
[0046] Please see Figures 1 to 6 The rainproof film 2 is fixed at one end to the roller 1 and can be wound on the roller 1. It has a retracted state and an unfolded state. In the retracted state, the rainproof film 2 is wound on the roller 1. In the unfolded state, the rainproof film 2 covers the area above the door 201 after it is opened. The drive component 3 drives the roller 1 to rotate to switch between the retracted and unfolded states. In rainy weather, when the door 201 is opened, the drive component 3 can drive the roller 1 to rotate to switch the rainproof film 2 to the unfolded state. After unfolding, the rainproof film 2 covers the area above the door 201 after it is opened, blocking rainwater from dripping onto the seat edges, door sills and the cabin. This effectively solves the problem of rainwater dripping onto the seats and door sills, avoiding affecting the comfort of the ride. In addition, when users get in and out of the car, the area after the door 201 is opened will not be exposed to rainwater. This solves the pain points of rainwater dripping into the cabin when users get in and out of the car in rainy weather and getting wet when closing an umbrella, significantly improving the user's experience of getting in and out of the car in inclement weather. The end of the rainproof film 2 can be fixed to the roller 1 in various ways that are easy for those skilled in the art to conceive of, such as welding, bonding, riveting, etc.; however, in order to further improve the firmness of the connection, the end of the rainproof film 2 can be embedded in the roller 1 to prevent the rainproof film 2 from falling off.
[0047] Please see Figures 1 to 2 In one embodiment of the present invention, the vehicle rainproof device 100 may include a storage box 4, which is used to install on the roof of the vehicle 200. The storage box 4 has an opening 41 on the side facing the door 201. The roller 1 and the drive component 3 are both located inside the storage box 4. In the stored state, the rainproof film 2 is wound around the roller 1 and stored in the storage box 4. In the unfolded state, the rainproof film 2 extends out of the opening 41 and covers the area above the door 201 after it is opened. That is, the storage box 4 integrates the roller 1, the drive component 3 and the rainproof film 2 on the roof with a semi-closed structure with an opening 41 on one side. The structure is compact and the installation is simple and convenient. The rainproof film 2 is completely hidden inside the storage box 4 in the stored state, which not only avoids the risk of wind resistance or scratches caused by protruding parts, but also blocks ultraviolet rays, sand and dust, etc., significantly delaying material aging and damage, and extending the service life of the device. The storage box 4 can be installed on the roof of the vehicle 200 using conventional techniques in this field, such as riveting, bolting, welding, etc. The shape of the storage box 4 includes, but is not limited to, triangular, quadrilateral, pentagonal, circular, irregular, etc.
[0048] To enable the drive element 3 to drive the scroll 1 to rotate and switch between the storage and unfolded states, various structural forms readily conceived by those skilled in the art can be adopted. For example, the drive element 3 could be a manual crank located inside the vehicle, connected to the scroll 1 via a transmission mechanism such as gears. However, for ease of implementation, the present invention preferably adopts the following structural form:
[0049] Please see Figures 1 to 2 In one embodiment of the present invention, the driving component 3 can be a drive motor, and the output shaft of the drive motor drives the roller 1. This motor-driven method allows the user to trigger the motor with a single button inside the vehicle, controlling its forward or reverse rotation, thereby rotating the roller 1 and switching the rainproof film 2 between its retracted and unfolded states. Compared to a manual crank, this eliminates the tedious manual operation of opening and closing the film, improving convenience and safety when getting in and out of the vehicle in rainy weather. It is conceivable that the output shaft of the drive motor can directly drive the roller 1, or it can indirectly drive the roller 1 through a transmission structure such as gears. However, to reduce space occupation, the present invention preferably uses the output shaft of the drive motor to directly drive the roller 1.
[0050] The rainproof film 2 in this invention can be made of conventional high-strength, lightweight, and waterproof flexible plastic film, or it can be made of special materials with shape memory function (such as high-modulus elastic polyester fiber woven film, shape memory alloy film, etc.). The rainproof film 2 made of special materials can not only be rolled onto the roller 1, but also self-supports itself into an arch upon unfolding, without any additional support components. However, to consider different vehicle models, cost, and process versatility, please refer to [the relevant documentation / reference]. Figures 1 to 2In one embodiment of the present invention, the vehicle rainproof device 100 may further include a support member, which provides structural support for the rainproof film 2 in the unfolded state, so that the rainproof film 2 is kept in the unfolded state. In rainy weather, when the car door 201 is opened, the drive member 3 drives the roller 1 to rotate and switch the rainproof film 2 to the unfolded state. At this time, the support member provides structural support for the rainproof film 2, so that the rainproof film 2 is stably kept in the unfolded state, providing sufficient wind resistance for the rainproof film 2. Even in crosswinds or oblique rain, it can maintain a flat posture, further improving the convenience and safety of getting in and out of the car in rainy weather.
[0051] Please see Figures 1 to 2 The support member can adopt various structural forms readily conceived by those skilled in the art. However, to improve convenience, the support member provides structural support to the rainproof film 2 at the moment of unfolding, enabling the rainproof film 2 to form a rigid structure and remain stably in the unfolded state. When the rainproof film 2 is retracted and rolled up, the support member can be rolled up and stored together with the rainproof film 2. The specific structure of the support member is as follows:
[0052] Please see Figures 1 to 2 In one embodiment of the present invention, the support member can be an airbag 5 disposed on the rainproof film 2. The vehicle rainproof device 100 also includes an inflator 6. In the unfolded state, the inflator 6 inflates the airbag 5 to provide structural support for the rainproof film 2, keeping the rainproof film 2 in the unfolded state. In this way, the combination of airbag 5 and inflator 6 is used as the support member. At the moment the rainproof film 2 unfolds, the inflator 6 quickly inflates the airbag 5, and the airbag 5 forms a rigid structure to provide structural support for the rainproof film 2, keeping the rainproof film 2 stably in the unfolded state. When the rainproof film 2 is retracted and rolled up, the airbag 5 deflates and restores its flexible structure, and is rolled up and stored together with the rainproof film 2. The diameter increase is small, reducing space occupation, not damaging the wind resistance of the vehicle body appearance, and no additional storage space is required, resulting in higher lightweight and reliability.
[0053] Please see Figures 1 to 2 In one embodiment of the present invention, an airbag 5 may be provided on the outer edge of the rainproof film 2. By placing the airbag 5 on the outer edge of the rainproof film 2, a ring-shaped inflatable beam can be formed first when it is unfolded, which instantly provides a tension frame for the far end of the rainproof film 2, the free edge most susceptible to wind load deformation, preventing the edge from rolling up and rainwater from flowing back in, thus improving stability.
[0054] The inflator 6 can take various structural forms readily conceived by those skilled in the art, such as a manually compressible airbag 5, which has a built-in one-way air inlet valve and can be inflated by squeezing; however, for ease of implementation, please refer to [the relevant documentation]. Figure 2In one embodiment of the present invention, the inflator 6 can be an electric air pump, the air outlet of which is connected to the airbag 5. Compared with the manual compression of the airbag 5, it eliminates the need for continuous manual squeezing, resulting in faster inflation and lower labor intensity. Users can trigger the inflation of the airbag 5 with a single button press inside the vehicle, eliminating the need for tedious manual operation and improving the convenience and safety of getting in and out of the vehicle in rainy weather. Furthermore, it can accurately set and automatically maintain the target air pressure, avoiding over-inflation or under-inflation and improving safety. Preferably, the electric air pump is connected to the root of the airbag 5, that is, the end of the airbag 5 closest to the roller 1.
[0055] Please see Figure 2 In one embodiment of the present invention, the roller 1 can be a hollow roller, and the electric air pump is located inside the roller 1. In this way, the roller 1 is set as a hollow roller and the electric air pump is built into its cavity, so that the inflation device is coaxially integrated with the roller 1, without taking up extra space, and the arrangement is compact. In addition, the roller can protect the air pump, prevent mud, water and dust from directly entering, and extend the life of the motor.
[0056] In one embodiment of the present invention, the support member can be a hinge disposed on the rainproof film 2. The hinge extends along the unfolding direction of the rainproof film 2. In the retracted state, the hinge bends to conform to the shape. In the unfolded state, the hinge is rigidly straightened to provide structural support for the rainproof film 2, keeping the rainproof film 2 in the unfolded state. In this way, by using a hinge as a support member, at the moment the rainproof film 2 is unfolded, the hinge forms a rigid structure to provide structural support for the rainproof film 2, keeping the rainproof film 2 stably in the unfolded state. When the rainproof film 2 is retracted and rolled up, the hinge restores its flexible structure and is rolled up and stored together with the rainproof film 2. The diameter increment is small, reducing the space occupation and eliminating the need for additional storage space.
[0057] Please see Figures 1 to 2 In one embodiment of the present invention, the vehicle rainproof device 100 further includes a solar power module 7 and a battery. The solar power module 7 and the battery are electrically connected to convert solar energy into electrical energy and store it in the battery. The battery is electrically connected to the drive unit 3 and the inflation unit 6 to provide electrical energy. Thus, the rainproof device using the combination of solar power module 7 and battery can convert solar radiation energy into electrical energy and store it efficiently, realizing independent power supply for the device, without relying on the main power supply of the vehicle 200, simplifying installation and wiring, ensuring the continuous operation capability of the rainproof device under harsh weather conditions, and significantly improving the reliability and environmental adaptability of the vehicle rainproof device 100.
[0058] Please see Figure 3 The present invention also provides a control method for a vehicle rainproof device 100, which is used to control the vehicle rainproof device 100. The structure of the vehicle rainproof device 100 is the same as above, and will not be described again here.
[0059] Please see Figure 3 The control methods include:
[0060] Step S1: Determine whether the door 201 of vehicle 200 is in an open or closed state;
[0061] In this step, to identify the open / closed state of the car door 201, various methods readily conceived by those skilled in the art can be employed. For example, a sensor switch can be installed at the car door 201. When the car door 201 is closed, pressing the sensor switch activates the circuit, indicating that the car door 201 is closed. When the car door 201 is opened, the sensor switch pops up, deactivating the circuit, indicating that the car door 201 is open. However, to achieve accurate identification of the open / closed state of the car door 201, this invention adopts the following structural form:
[0062] Please see Figure 6 In one embodiment of the present invention, the vehicle rainproof device 100 may further include a magnet 9 and a magnetic attraction sensor 8. One of the magnet 9 and the magnetic attraction sensor 8 is fixed to the door 201 of the vehicle 200, and the other is fixed to the vehicle rainproof device 100. That is, the magnet 9 and the magnetic attraction sensor 8 are respectively installed at corresponding positions on the door 201 and the vehicle rainproof device 100, and their fixed positions can be interchanged. In this case, the control method may include:
[0063] If the magnetic sensor 8 loses the magnetic signal from the magnet 9, it is determined that the door 201 of the vehicle 200 is in the open state, and it continues to determine whether the ambient humidity meets the preset conditions. That is, when the door 201 is open, the relative displacement between the magnetic sensor 8 and the magnet 9 causes the magnetic signal to be interrupted, and it is determined that the door 201 is in the open state and triggers subsequent external environment detection.
[0064] If the magnetic sensor 8 receives the magnetic signal from the magnet 9, it determines that the door 201 of the vehicle 200 is closed. It then controls the drive unit 3 to drive the roller 1 to rotate, switching the rainproof film 2 to the retracted state or maintaining the retracted state. That is, when the door 201 is closed, the magnetic sensor 8 receives a stable magnetic signal again, determines that the door 201 is closed, and immediately controls the drive unit 3 to start the roller 1 to rotate, quickly switching the rainproof film 2 to the retracted state or maintaining the retracted state, so as to avoid affecting the normal driving of the vehicle 200.
[0065] Step S2: If the door 201 of vehicle 200 is open, determine whether the external environment is rainy.
[0066] In this step, to detect whether the external environment of the vehicle is rainy, various methods readily conceived by those skilled in the art can be used, such as capturing images of the window area using an in-vehicle camera and analyzing the images using image recognition algorithms to determine whether there are falling water droplet trajectories; however, for ease of implementation and more accurate detection of whether the external environment of the vehicle is rainy, this invention adopts the following structural form:
[0067] In one embodiment of the present invention, the vehicle rainproof device 100 may further include a humidity-sensitive resistor. The resistance of the humidity-sensitive resistor decreases as the ambient humidity increases. By configuring a humidity-sensitive resistor in the vehicle rainproof device 100, the change in ambient humidity can be converted into a resistance signal in real time and accurately, thereby reliably determining whether it is raining outside the vehicle, effectively avoiding false triggering, and ensuring that the rainproof film 2 only unfolds in time when it is actually raining and the car door 201 is open, thereby improving the reliability of protection, energy saving and user experience.
[0068] Step S3: If the external environment of the vehicle is rainy, control the drive unit 3 to drive the roller 1 to rotate so as to switch the rainproof film 2 to the unfolded state.
[0069] In conjunction with the above embodiments, in this step, if the resistance of the humidity-sensitive resistor is less than a preset threshold, it is determined that the external environment is rainy. The drive unit 3 is controlled to drive the roller 1 to rotate to switch the rainproof film 2 to the unfolded state. That is, when the car door 201 is open and the resistance of the humidity-sensitive resistor is less than the preset threshold, it is determined that the car door 201 is in the open state and the environment is rainy. The drive unit 3 is then controlled to drive the roller 1 to rotate to switch the rainproof film 2 to the unfolded state. At this time, the inflation unit 6 is controlled to work to inflate the airbag 5 to provide structural support for the rainproof film 2, so that the rainproof film 2 remains in the unfolded state. If the resistance of the humidity-sensitive resistor is greater than or equal to a preset threshold, it is determined that the external environment is not rainy. The drive unit 3 is then controlled to rotate the roller 1 to switch the rainproof film 2 to a retracted state or maintain the retracted state. That is, when the door 201 is open and the resistance of the humidity-sensitive resistor is greater than or equal to the preset threshold, it is determined that the door 201 is open and the environment is not rainy. The drive unit 3 is immediately controlled to start the roller 1 to rotate, quickly switching the rainproof film 2 to a retracted state or maintaining the retracted state. At this time, the inflation unit 6 is controlled to deflate the airbag 5 or disable it to avoid affecting the normal driving of the vehicle 200. The preset threshold can be arbitrarily set according to the actual vehicle environment, climate differences, and sensitivity requirements to ensure that the rain detection threshold is both accurate and adaptable.
[0070] When the driver or passenger opens the car door 201, the magnet 9 on the door 201 moves and separates from the magnetic sensor 8. The sensor loses its magnetic signal, indicating that the door 201 is open and the resistance of the humidity-sensitive resistor decreases due to moisture. This immediately triggers the vehicle rainproof device 100 to enter working mode, driving the motor to rotate forward and causing the roller 1 to switch the rainproof film 2 to the unfolded state. Subsequently, the electric air pump inflates the airbag 5 of the rainproof film 2. The support provided by the airbag 5 causes the rainproof film 2 to bulge horizontally, forming a rigid shielding structure that covers the cabin entrance area after the door 201 is opened. After the passengers have finished getting on and off the vehicle and the door 201 is closed, the magnet 9 and the magnetic sensor... When the device 8 is re-attached, the sensor receives a magnetic signal, triggering the device to enter a reset state. At this time, the electric air pump quickly deflates the airbag 5 of the rainproof film 2, restoring it to a flexible state. Then, the drive motor rotates in the opposite direction, driving the roller 1 to switch the rainproof film 2 to the storage state and retract it into the storage box 4, completing one work cycle. This can achieve automated closed-loop control, avoiding accidental triggering in non-rainy weather or while driving, improving intelligence and user-friendliness, and better enhancing the user's experience when getting in and out of the car in inclement weather. Furthermore, the drive motor and electric air pump only work for a short time when the car door 201 is opened and closed, resulting in low energy consumption, and can still maintain normal operation even with continuous use.
[0071] Please see Figures 4 to 6 This invention provides a vehicle 200, including a door 201 and the aforementioned vehicle rainproof device 100. The structure of the vehicle rainproof device 100 is the same as described above, and will not be repeated here. The vehicle 200 can be any type of vehicle 200 that is easily conceived by those skilled in the art, specifically covering, but not limited to: front-engine front-wheel drive sedans, front-engine rear-wheel drive luxury sedans, mid-engine rear-wheel drive sports cars and four-wheel drive sports SUVs, battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), range-extended electric vehicles (REEVs), and hydrogen fuel cell vehicles (FCEVs); and is also applicable to the field of special vehicles, such as police vehicles, medical ambulances, high-end business reception vehicles, and special vehicles for sports events.
[0072] Please see Figures 4 to 6 In one embodiment of the present invention, each door 201 of the vehicle 200 may be provided with a vehicle rainproof device 100, that is, each door 201 of the vehicle 200 is provided with a vehicle rainproof device 100, thereby allowing the corresponding rainproof film 2 to be deployed independently and partially when any door 201 is opened, achieving synchronous or selective rainproof coverage of all doors 201, preventing rainwater from entering the vehicle from any open door 201, and improving the overall rainproof coverage of the vehicle and the convenience of passengers getting on and off the vehicle.
[0073] In summary, the vehicle rainproof device, its control method, and the vehicle of this invention provide an automatic, fast, and fully covered integrated rainproof solution: the device is integrated into the vehicle roof, triggered by magnetic induction and powered independently by solar energy, allowing for quick installation on fuel or new energy vehicles without additional wiring, achieving immediate use. Its simple and reliable structure avoids the risk of failure associated with complex electronic or mechanical components. The solar panel-battery design provides a green, self-sufficient power source, aligning with energy conservation and environmental protection trends, while simplifying the overall vehicle wiring harness layout. Furthermore, the rainproof film, once unfolded, completely covers the cabin entrance area after the doors are opened, preventing rainwater from dripping onto the seats and door sills, achieving full rainproof coverage. Simultaneously, the humidity-sensitive resistor and magnetic sensor work together, automatically extending and retracting the rainproof film when the doors are opened or closed in rainy weather, requiring no occupant intervention. This design balances convenience and technological sophistication, with a compact structure that does not obstruct the driver's view or damage the vehicle's appearance, meeting user needs.
