Reference to related applications

[0001] The present application is based on Taiwanese patent application No. 114206120, filed on June 13, 2025, which is expressly incorporated by reference into the present application, and claims its priority pursuant to 35 USC. Background of the invention 1. Field of invention

[0002] The present invention relates to a rain protection device for vehicles, in particular a non-visible rain protection device for vehicles. 2. Description of the state of the art

[0003] Due to the limited space inside the vehicle, it is difficult for the driver and passengers to manually open or close an umbrella in such a confined space on rainy days. Usually, part of one's body has to extend outside the vehicle to open or close the umbrella properly. Therefore, getting wet when entering or exiting the vehicle is almost inevitable.

[0004] To solve this problem, umbrellas have been developed that can be quickly opened or closed with one hand in the limited space available when opening a vehicle door, thus reducing the need for two-handed operation and minimizing contact between vehicle occupants and the rain. However, when folding the umbrella, one hand still protrudes from the vehicle and gets wet. Furthermore, entering and exiting the vehicle requires bending and lowering one's head. Therefore, while holding the umbrella, it is generally difficult to adjust its position without getting wet while changing posture. Thus, there is a need for a vehicle rain cover device to eliminate the inconvenience of handling an umbrella when entering and exiting a vehicle.

[0005] To overcome these disadvantages, the present invention provides an invisible rain protection device for vehicles to mitigate or eliminate the aforementioned problems. Brief description of the invention

[0006] The object of the present invention is to provide an invisible rain protection device for vehicles.

[0007] The present invention provides a non-visible rain protection device for vehicles, comprising: at least one high-pressure air deflector designed to be installed in a first elongated opening defined by an upper lateral part of at least one vehicle door frame; a blower with a high-pressure air outlet communicating with the high-pressure air deflector; a switch configured to output an open signal and a close signal; and a control unit that is electrically connected to the blower and the switch to start or stop the blower in response to the open and close signals from the switch.

[0008] As described above, in the concealed rain protection device for vehicles according to the present invention, the high-pressure air deflector is primarily installed in the first elongated opening on the vehicle door frame. This arrangement does not interfere with the normal opening and closing of the vehicle door. When the vehicle door is opened, the control unit receives the opening signal from the switch and activates the blower. The blower is activated to generate a high-pressure airflow and direct it to the high-pressure air deflector. This causes the high-pressure air to flow out of the upper lateral part of the vehicle door frame corresponding to the open door, forming a concealed rain protection zone at the top between the open vehicle door and the corresponding vehicle door frame.The concealed rain protection area provides shelter from rain for people entering and exiting the vehicle. This allows drivers and passengers to enter or exit the vehicle while protected from direct rain, without the need for a physical canopy or mechanical cover.

[0009] Further tasks, advantages and novel features of the invention are illustrated by the following detailed description in conjunction with the accompanying drawings.

Detailed description of the embodiments

[0010] The present invention proposes a rain protection device technology for vehicles. A detailed description of the present invention is provided, along with several embodiments and diagrams for better illustration.

[0011] According to the Fig. 1A and Fig. 3. The present invention provides a concealed rain protection device for a vehicle 10. The concealed rain protection device is installed in a vehicle body structure 11, which has several vehicle door frames 12, and a first elongated opening 122 is defined by an upper lateral part 121 of one of the vehicle door frames 12. In one embodiment, as shown in Fig. As shown in Figure 4, a first elongated opening 122 can be formed in each vehicle door frame 12 of the vehicle body structure 11. For example, in a four-door vehicle, a first elongated opening 122 is formed in each of the four door frames 12. Furthermore, as shown in Fig. As shown in Figure 1B, a second elongated opening 122a is also formed on the inside of at least one vehicle door 13.

[0012] According to Fig. 5 The non-visible rain protection device of the present invention comprises at least a high-pressure air deflector 20, a blower 30, a switch 40 and a control unit 50.

[0013] The at least one high-pressure air deflector 20 is installed within the corresponding first elongated opening 122 on the vehicle door frame 12. As shown in Fig. As shown in Figure 4, in one embodiment, if the vehicle body structure 11 is provided with a plurality of first elongated openings 122, a corresponding plurality of high-pressure air deflectors 20 can be installed therein. In the present embodiment, as shown in the Fig. 1A and Fig. As shown in Figure 3, the first elongated opening 122 is arranged on the upper lateral part 121 of the vehicle door frame, which corresponds to the driver's door 13 of the vehicle, without the invention being limited thereto. In another embodiment, as shown in the Fig. 2A and Fig. As shown in Figure 2B, each of the high-pressure air deflectors 20, 20' has an inclined inner air duct 21, 21'. The inclined inner air duct 21 has a slope in Fig. 2A is smaller than the inclination of the inclined inner air duct 21' in Fig. 2B. Therefore, an angle θ1 between the inclined inner air duct 21 and the first elongated opening 122 of the upper lateral part 121 differs from an angle θ2 between the inclined inner air duct 21' and the first elongated opening 122 of the upper lateral part 121, where θ1 < θ2. Preferably, these angles θ1 and θ2 can be selected from a range of 5° to 60°. Therefore, the present invention is suitable for installation in vehicles of different heights. For example, Fig. 2A is suitable for larger vehicles, while Fig. 2B is suitable for shorter vehicles. For even larger vehicles, whose height exceeds that of most vehicles, the inclination of the inclined inner air duct 21 can be adjusted. Fig. 2A be zero (θ1 = 0), so that the angle θ1 can be selected from an angle between 0° and 60°. According to Fig. 1B Another high-pressure air deflector 20 can be installed inside the second elongated opening 122a to adjust the direction of high-pressure air from the second elongated opening 122a.

[0014] According to Fig. 3. The blower 30 can be installed at any position within the vehicle body structure 11. However, for optimal airflow efficiency, it is advantageous for the blower 30 to be located on the top of the vehicle body structure 11, although the invention is not limited to this. An air outlet 31 of the blower 30 is connected via an air duct 32 to the at least one high-pressure air deflector 20, so that the high-pressure air generated by the blower 30 can be easily directed to the at least one high-pressure air deflector 20. In addition, the air inlet of the blower 30 (not shown in the figure) can be connected either to the inside or to the outside of the vehicle. It should be noted that when the vehicle's air conditioning or heating is switched on, the air inlet should be connected to the outside to prevent cooled or heated air from escaping from the vehicle's interior.Conversely, the air intake can be connected to the interior if the vehicle has been stationary for a long time or if there are odors in the interior, in order to help push out stale air, thereby reducing unpleasant odors.

[0015] Switch 40 outputs an opening or closing signal corresponding to the opening and closing of the vehicle door 13, which corresponds to the vehicle door frame 12 on which the high-pressure air deflector 20 is installed. Specifically, switch 40 can be a physical switch or a sensor-based switch and can be installed on the vehicle door frame 12 or on the vehicle door 13 of the vehicle body structure 11 to detect the opening and closing of the vehicle door 13. When switch 40 detects that the vehicle door 13 is being opened, the opening signal is output. Conversely, the closing signal is output when switch 40 detects that the vehicle door 13 is being closed.

[0016] The control unit 50 is electrically connected to both the blower 30 and the switch 40. When the control unit 50 receives the opening signal from the switch 40, it activates the blower 30 to generate high-pressure air and supply the high-pressure air to the at least one high-pressure air deflector 20. When it receives the closing signal from the switch 40, it stops the blower 30. In other words, when the vehicle door 13 is opened and the switch 40 issues the opening signal, the high-pressure air is blown out of the first elongated opening 122 and forms an invisible rain protection zone A between the vehicle door frame 12 and the open door 13, as shown in Fig. Figure 3 is shown. Conversely, when the vehicle door 13 is closed and the switch 40 sends the closing signal, the blower 30 stops, so that no more high-pressure air is generated. Additionally, the control unit 50 can be electrically connected to a rain detection signal wire to receive a rain detection signal and control the blower's operating speed accordingly. Therefore, automatic adjustment of the blower 30's operating speed is achieved based on the rainfall intensity outside the vehicle. That is, the high-pressure airflow intensity is varied according to the amount of rain. Furthermore, as shown in Fig. As shown in Figure 6, several function keys 43 are electrically connected to the control unit 50 to manually increase or decrease the airflow intensity. When the control unit 50 receives a key signal, it adjusts the operating speed of the fan 30 accordingly, allowing the user to manually control the airflow intensity. Furthermore, as shown in Figure 6, several function keys 43 are electrically connected to the control unit 50 to manually increase or decrease the airflow intensity. Fig. As shown in Figure 1B, when the vehicle door 13 is detected as open and the blower 30 is activated, the high-pressure air generated by the blower 30 is also supplied to the high-pressure air deflector 20, which is installed inside the second elongated opening 122a on the vehicle door 13. Therefore, a high-pressure airflow directed upwards and diagonally inwards relative to the vehicle door frame 12 prevents high-pressure air and rainwater from being blown onto adjacent vehicles or pedestrians. In one embodiment, an additional blower (not shown) can be installed inside the vehicle door 13 to generate high-pressure air directly at the high-pressure air deflector 20 at the second elongated opening 122a.

[0017] Fig.Figure 6 shows a second embodiment of the concealed rain protection device for a vehicle 10 according to the present invention. The concealed rain protection device comprises at least one high-pressure air deflector 20, a blower 30, a remote-controlled switch 41, a control unit 50, and a remote control 42. The remote-controlled switch 41 can receive remote control signals from the remote control 42 within a certain communication range. If the remote control signal contains an opening command, the remote-controlled switch 41 outputs an opening signal to the control unit 50. Conversely, the switch 41 outputs a closing signal to the control unit 50 if the remote control signal contains a closing command.Therefore, in this second embodiment of the present invention, the driver or occupants can use the remote control 42 to activate or deactivate the invisible rain protection device without having to wait for the door opening / closing detection to trigger its operation.

[0018] Based on the foregoing description, in the concealed rain protection device for vehicles according to the present invention, the at least one high-pressure air deflector is primarily aligned with the first elongated opening on the vehicle door frame and / or with the second elongated opening on the inside of the vehicle door. This arrangement does not interfere with the normal opening and closing of the door. When the vehicle door is opened, the control unit activates the blower to generate the high-pressure air, which is then supplied to the at least one high-pressure air deflector. As a result, the high-pressure air is blown out of the upper lateral part of the vehicle door frame corresponding to the open door to form a concealed rain protection zone. This concealed rain protection zone provides protection from rain for persons entering and exiting the vehicle.This allows the driver and passengers to enter and exit the vehicle without being directly exposed to rain, without the need for a physical canopy or mechanical cover.

[0019] Although numerous features and advantages of the present invention, along with details of its structure and features, have been set forth in the foregoing description, the disclosure serves only for illustrative purposes. Within the principles of the invention, modifications to the details, particularly regarding the shape, size, and arrangement of parts, may be made to the full extent indicated by the general meaning of the terms in the appended claims.
