Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile electronic control, in particular to a door opening warning and control device. BACKGROUND

[0002] With the increase of the number of automobiles, the accidents of collision between the opened door and the rear vehicle (including motor vehicle and non-motor vehicle) occur frequently, especially when the vehicle is temporarily parked on the roadside, the person inside the vehicle often cannot detect the fast approaching moving object from the rear, which easily leads to safety accidents. The door opening reminding function of the existing automobile is relatively single, mostly only relying on the rearview mirror or the observation of the driver, and the warning effect is limited. At the same time, the linkage of the central locking system and the door opening operation of some vehicles is insufficient, which cannot realize reasonable locking and unlocking control at the same time, and it is difficult to effectively avoid accidents. SUMMARY

[0003] The purpose of the present application is to provide a door opening warning and control device.

[0004] In order to achieve the above purpose, the present application provides the following technical scheme: The door opening warning and control device of the present application comprises a Hall relay module, two five-pin relays, a Hall switch, a small magnet, a radar module, an LED lamp, a voice prompt module, a central locking system and an electronic button.

[0005] The Hall switch is fixed in the door handle box, and the small magnet is fixed on the handle, which are cooperating structures for detecting the state of the handle. The Hall switch is electrically connected with the Hall relay module, and the output end of the Hall relay module is electrically connected with the two five-pin relays, and the two five-pin relays are connected to the negative pole of 12V power supply. The working logic of the Hall switch is: when close to the small magnet, power off, and when far away, power on. When the user pulls up the handle, the small magnet moves with the handle and separates from the Hall switch, the Hall switch triggers and outputs a signal to the Hall relay module, and the Hall relay module converts the signal into 12V power output to supply power to the two five-pin relays; when the handle is not pulled, the small magnet keeps close to the Hall switch, the Hall switch does not output a signal, and the Hall relay module does not output 12V power.

[0006] The radar module is installed at the tail of the vehicle or the corresponding position of the door, and is used for detecting whether a moving object (such as a vehicle, a pedestrian, a non-motor vehicle or the like) is close to the rear of the vehicle in real time. The radar module is electrically connected with the LED lamp, the voice prompt module and the central locking system respectively, the LED lamp is installed below the outside door handle, and the voice prompt module is integrated in the in-vehicle audio system or is independently arranged. When the radar module detects that a moving object is close to the rear, a trigger signal is immediately sent: the LED lamp is controlled to continuously flash to remind the rear person outside the vehicle; the voice prompt module is controlled to issue a voice prompt of "be careful, there is a car behind", to warn the person inside the vehicle; and the central locking system is controlled to automatically lock, to avoid the misoperation of opening the door.

[0007] When the central locking system is locked and the user scratches the half handle, the Hall switch is separated from the small magnet, the Hall relay module outputs 12V power to drive two five-pin relays to act, and then the door is unlocked, so that the user can normally open the door and get off the vehicle; when the user presses the original electronic button, the current passes through the two five-pin relays to access the original electronic button opening door program, without passing through the Hall switch control, so that the central locking system can be normally opened, and the original opening door operation logic is not affected.

[0008] The present application has the advantages that: The present application can detect the moving object behind the vehicle in real time through the radar module, cooperate with the external warning of the LED lamp and the in-vehicle voice prompt, double remind to reduce the opening door collision risk, and improve the driving and parking door safety. The Hall switch and the small magnet are matched to accurately detect the handle operation state, the Hall relay module realizes the conversion of the signal and the power, drives the relay to control the door lock, and the door can be opened only by scratching the half handle in the locked state, so that the misoperation of opening the door is avoided; the electronic button opening door retains the original vehicle program, and has strong adaptability. The mature Hall switch, the relay and the radar module are adopted, the components have high universality, the installation is convenient, the original vehicle structure does not need to be greatly changed, the cost is low, and the application is convenient.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0014] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0015] See Figs. 1-2 The present invention provides a door opening warning and control device, including a Hall relay module 1, two five-pin relays 2, a Hall switch 3, a small magnet 4, a radar module 5, an LED light 6, a voice prompt module 7, a central locking system 8, and electronic buttons 9.

[0016] Hall switch 3 is fixed inside the door handle box, and small magnet 4 is fixed on the handle. The two are a mating structure used to detect the handle's actuation state. Hall switch 3 is electrically connected to Hall relay module 1, and the output of Hall relay module 1 is electrically connected to two five-pin relays 2, both of which are connected to the negative terminal of a 12V power supply. The operating logic of Hall switch 3 is as follows: it is de-energized when close to small magnet 4 and energized when far away. When the user pries open the handle, small magnet 4 moves with the handle and separates from Hall switch 3. Hall switch 3 is triggered and outputs a signal to Hall relay module 1. Hall relay module 1 converts the signal into a 12V power output to power the two five-pin relays 2. When the handle is not pried open, small magnet 4 remains in contact with Hall switch 3, Hall switch 3 does not output a signal, and Hall relay module 1 does not output 12V power.

[0017] The radar module 5 is installed at the rear of the vehicle or at the corresponding location on the door to detect in real time whether there are moving objects (such as vehicles, pedestrians, non-motorized vehicles, etc.) approaching behind the vehicle. The radar module 5 establishes electrical connections with the LED light 6, the voice prompt module 7, and the central locking system 8. The LED light 6 is installed below the exterior door handle, and the voice prompt module 7 is integrated into the in-vehicle audio system or set up independently. When the radar module 5 detects a moving object approaching from behind, it immediately sends a trigger signal: controlling the LED light 6 to flash continuously to alert people outside the vehicle; controlling the voice prompt module 7 to issue a voice prompt "Beware of a vehicle approaching from behind" to warn the occupants of the vehicle; and simultaneously controlling the central locking system 8 to automatically lock the doors to prevent accidental opening by personnel.

[0018] After the central locking system 8 is locked, when the user pulls the half-latch, the Hall switch 3 separates from the small magnet 4. The Hall relay module 1 outputs 12V power to drive the two five-pin relays 2 to unlock the car door, allowing the user to open the door and get out of the car normally. When the user presses the original car electronic button 9, the current passes through the normally closed contacts of the two five-pin relays 2 to access the original car electronic button 9's door opening program. It does not need to be controlled by the Hall switch 3, so the central locking system 8 can open the door normally without affecting the original car's original door opening operation logic.

[0019] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0020] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
