Description

Technical Field

[0001] The utility model relates to the field of electronic rearview mirrors, in particular to a foldable electronic rearview mirror for a car. Background Art

[0002] With the continuous improvement of my country's national economy and the rapid development of the automobile industry, cars have become an indispensable household tool in modern life. Rearview mirrors are essential devices on any vehicle. Although they have little impact on the driving performance of the car, nearly 30% of road traffic accidents and 70% of highway accidents are caused by drivers not understanding the surrounding environment in time. Therefore, the existence of rearview mirrors is unquestionable. Its field of vision is particularly important for drivers to understand road conditions. At present, rearview mirrors are all foldable front and back. Their main function is to retract the rearview mirror to prevent damage when parking. With the maturity of electronic rearview mirror technology and the opening of laws and regulations, electronic rearview mirrors are gradually replacing mechanical rearview mirrors. After the mechanical rearview mirror or electronic rearview mirror is folded front and back, its rearview function is significantly reduced.

[0003] According to the published patent 202320946758.9, the foldable electronic rearview mirror for automobiles includes a vehicle body or a door and an electronic rearview mirror, and an angle sensor for reading the rotation angle of the electronic rearview mirror. A motor is fixedly installed inside the support arm, and a motor rotor is fixedly installed at the output end of the motor. An electronic rearview mirror cantilever is fixedly arranged on the motor rotor. The angle sensor reads the relative rotation angle between the electronic rearview mirror and the support arm, and transmits the read angle to the motor control circuit through a wiring harness. The motor control circuit reads the input signal of the angle sensor to control the rotation of the motor. The motor drives the electronic rearview mirror cantilever to fold through the motor rotor. Through different folding positions, the passability of the vehicle on narrow roads is met, and the interactive effect of the vehicle is enriched. The electronic rearview mirror can always be in working state and present the surrounding environment, providing the coordinate system data required for the auxiliary driving function, which is convenient for the driver to observe the surrounding environment and road conditions, and make timely judgments. In the process of realizing the utility model, The inventor found that at least the following problems have not been solved in the prior art: although the angle sensor reads the relative rotation angle between the electronic rearview mirror and the support arm, and transmits the read angle to the controller of the electronic rearview mirror through the wiring harness, which is used to analyze the coordinates of the upper module of the electronic rearview mirror in the vehicle coordinate system and provide the coordinate system conversion data required for the realization of the assisted driving function, the motor drives the electronic rearview mirror cantilever to fold through the motor rotor, and the electronic rearview mirror presents different surrounding environments through different folding positions, but in the process of use, the traditional automobile folding electronic rearview mirror, after folding the electronic rearview mirror, the electronic rearview mirror is not completely fitted with the car door, and the electronic rearview mirror still occupies a certain distance, causing the electronic rearview mirror to be scratched or collided, and the electronic rearview mirror mainly relies on the electronic camera to shoot and transmit the picture. When there is dirt on the surface of the electronic camera, it will seriously affect the effect of the picture display compared to the ordinary rearview mirror, resulting in lower safety. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a foldable electronic rearview mirror for a car to solve the problem that the current traditional foldable electronic rearview mirror for a car does not completely fit with the car door after the electronic rearview mirror is folded, and the electronic rearview mirror still occupies a certain distance, causing the electronic rearview mirror to be scratched or collided. Moreover, the electronic rearview mirror mainly relies on an electronic camera to capture and transmit the picture. When there is dirt on the surface of the electronic camera, it will seriously affect the picture display effect compared with an ordinary rearview mirror, resulting in a technical problem of low safety.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a car folding electronic rearview mirror, including a door body, and also including:

[0012] Preferably, a mounting hole is provided at the front end of the rearview mirror housing, and an electronic camera is installed inside the mounting hole.

[0013] Preferably, the electronic camera is connected to a display screen on the inner side of the vehicle door.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can directly open a folding groove matching the rearview mirror housing on the outer side of the vehicle door through the combination of the folding groove, the first micro motor and the rearview mirror housing. When the rearview mirror housing needs to be folded, the rearview mirror housing can be directly screwed into the folding groove through the first micro motor, so that after the rearview mirror housing is folded, it is completely in contact with the outer side of the vehicle door to form a plane, which solves the technical problem of the traditional automobile folding electronic rearview mirror, that after the electronic rearview mirror is folded, the electronic rearview mirror is not completely in contact with the vehicle door, and the electronic rearview mirror still occupies a certain distance, resulting in the electronic rearview mirror being scratched or collided.

[0016] 2. The utility model combines the folding groove, the second micro motor and the cleaning brush body. After the rearview mirror shell is folded, the second micro motor in the folding groove can be used to drive the cleaning brush body to rotate, thereby rotating and cleaning the electronic camera on the surface of the rearview mirror shell, realizing automatic cleaning of the electronic camera and eliminating manual cleaning. The cleaning mechanism and the folding mechanism are integrated into one, solving the problem that the electronic rearview mirror mainly relies on the electronic camera to capture and transmit the picture. When there is dirt on the surface of the electronic camera, it will seriously affect the picture display effect compared with ordinary rearview mirrors, resulting in a technical problem of lower safety.
