Description

Technical Field

[0001] This utility model relates to the technical field of car door opening safety, and more specifically, to a car door opening warning device. Background Technology

[0002] When a driver or passenger opens a car door without carefully observing the surroundings, the sudden opening of the door may cause a collision with vehicles or people behind or to the side.

[0003] In existing technologies, a common approach to reduce similar accidents relies on the vehicle's built-in passive warning systems. For example, placing warning stickers such as "Pay attention to the rear" in a prominent position on the inside of the door reminds the driver or passengers to check their surroundings before opening the door. Another approach is to add blind spot warning lights to the side mirrors; when the system detects an approaching vehicle, the light illuminates to warn the driver not to open the door unnecessarily. However, if the driver or passengers are inattentive and fail to notice the warning stickers or the warning lights on the side mirrors, the warning mechanism will fail, posing a high risk of collision. Utility Model Content

[0020] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0021] The car door opening warning device provided by this utility model includes a housing and a light panel 500. The housing has a cavity, in which a main control board 300 and a horn 400 are provided. The main control board 300 is provided with a controller and a communication element. The controller is electrically connected to the horn 400 and is connected to the light panel 500 through the communication element. The front of the housing is provided with a plurality of horn holes 101, and the horn 400 is arranged facing the horn holes 101. The back of the housing is provided with a fixing structure for fixing the housing to the inside of the car door. The front of the light panel 500 is provided with multiple LED beads 501, and the back of the light panel 500 is provided with an adhesion structure for adhering the light panel 500 to the inner glass surface of the vehicle window. The main control board 300 is also connected to a detection element for detecting the door opening action of the occupants of the vehicle.

[0022] The aforementioned car door opening warning device uses a fixing structure to fix the housing to the inside of the car door and an adhesive structure to adhere the light panel 500 to the inside of the car window glass. The device operates automatically when activated. When the detection element detects that someone inside the car is opening the door, the controller immediately emits an audible warning through the horn 400 and simultaneously illuminates the LED beads 501 on the light panel 500 through the communication element. The light emitted by the LED beads 501 shines through the glass to form a visual warning, thereby reminding the occupants of the car to pay attention to the situation behind them and reminding oncoming vehicles to avoid them. This effectively prevents traffic accidents caused by blind spots caused by door opening. The device is easy to install, compatible with various car models, and can reliably play a warning role in various environments.

[0023] Specifically, the housing includes an upper housing 100 and a lower housing 200, which are arranged vertically together to form a cavity. This facilitates the installation and maintenance of the entire device, and also results in a simple structure and low cost.

[0024] Specifically, the lamp board 500 is provided with multiple mounting grooves, and the lamp beads 501 are arranged in the mounting grooves.

[0025] The light panel 500 is attached to the upper part of the car window.

[0026] The speaker hole 101 is located on the front of the upper housing 100, while the fixing structure is located on the back of the lower housing 200. Just as the sound outlet and base of a speaker have distinct functions, the upper housing 100 is specifically responsible for the effective transmission of sound, ensuring that the warning sound emitted by the speaker 400 can be clearly diffused, while the lower housing 200 focuses on stable installation, firmly fixing the entire device to the inside of the car door through the fixing structure on the back. This ensures both the rationality of functional zoning and allows each part to perform its function, resulting in a more organized overall structure and easier installation and use.

[0027] The housing also includes a battery compartment 103, located on one side of the housing, while the main control board 300 and the speaker 400 are located on the other side. The battery compartment 103 contains a battery for power supply. This design simplifies the maintenance process, reduces the risk of interference between components, and makes the overall structure more practical and cost-effective.

[0028] Specifically, the upper housing 100 has a recessed mounting groove 102, in which a keypad 110 is mounted. The main control board 300 has a power switch 301, and the keypad 110 is connected to the power switch 301. In this way, the mounting groove 102 provides a mounting position for the keypad 110, protects the internal power switch 301 from accidental activation, and allows the user to easily operate the power switch 301 to control the start and stop of the device through the keypad 110.

[0029] In a preferred embodiment, multiple LED beads 501 are arranged in a straight line along the length of the light panel 500. This arrangement, similar to reflective warning strips on both sides of a road being arranged in a straight line, creates a continuous visual warning strip with a wider coverage area.

[0030] The light panel 500 is connected to a control box 510, which contains a power supply and communication circuit. The light panel 500 is connected to the controller via the communication circuit. In this way, the light panel 500 is provided with independent power support through its built-in power supply, and a signal channel is established between the light panel 500 and the controller through the communication circuit, ensuring that the warning commands can be transmitted quickly and stably.

[0031] The communication circuit includes a wireless communication module receiver.

[0032] Among them, the controller can be the main control MCU.

[0033] The communication element can be a wireless communication module in the 433 GHz band.

[0034] Specifically, the control box 510 can be placed in the trunk.

[0035] In this embodiment, the detection element includes an infrared receiver. The infrared receiver works in conjunction with the infrared transmitter. When a hand blocks the infrared light, the door opening action is detected, the speaker emits a warning sound, and multiple LEDs 501 are illuminated.

[0036] In this embodiment, the detection element includes a radar sensor. When a hand approaches the door handle in preparation to pull or trigger the door unlocking mechanism, the radar sensor accurately captures the hand movement trajectory by emitting a high-frequency microwave signal and receiving the reflected wave. Upon detecting the door opening action, the horn emits a warning sound and multiple LEDs 501 are illuminated.

[0037] In this embodiment, the adhesion structure includes a first adhesive strip that extends along the length of the light panel 500; the fixing structure includes a second adhesive strip that extends along the length of the housing. The first adhesive strip, arranged along the length of the light panel 500, ensures a more uniform contact area between the light panel 500 and the outer side of the vehicle body, preventing localized poor adhesion that could cause the light panel 500 to lift. Even when the vehicle encounters bumps while driving, it remains firmly attached and does not fall off. Similarly, the second adhesive strip allows the housing to stably adhere to the inner side of the door, allowing for fixing without drilling or screwing, thus avoiding damage to the vehicle body paint or door interior and simplifying installation.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
