Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted equipment, in particular to an electronic rearview mirror camera device. Background Art

[0002] The field of view of traditional rearview mirrors is limited by the vehicle body structure and angle, so the images that the driver can see are often limited, leaving the driver with many blind spots.

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.

[0018] Figure 1 This is a schematic structural diagram of an electronic rearview mirror camera device in one embodiment of the utility model; DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0020] Embodiment 1:

[0021] See also Figure 1 An electronic rearview mirror camera device 10 includes: a telephoto camera module 100, a distance measuring module 200 and a PCB board 300. The telephoto camera module 100 and the distance measuring module 200 are respectively arranged on the PCB board 300. The telephoto camera module 100 and the distance measuring module 200 are respectively connected to the in-vehicle display screen. The telephoto camera module 100 is used to collect images and transmit the collected images to the in-vehicle display screen. The distance measuring module 200 is used to obtain external vehicle information and transmit the collected external vehicle information to the in-vehicle display screen.

[0022] It should be noted that the telephoto camera module 100 is used to capture images from the rear of the car, and the images captured by the telephoto camera module 100 can be displayed on a display screen inside the car. During driving of the car, when an external vehicle appears in the depth of field of the telephoto camera module 100, the ranging module 200 will emit a light source and receive the light source that hits the external vehicle and bounces back. Thus, the distance between the vehicle and the external vehicle and the speed of the external vehicle can be calculated. Simultaneously, the external vehicle information obtained by the ranging module 200 is displayed on a display screen inside the car, which can better help the driver understand the conditions of the road outside the car, reduce the driver's need to shake his head left and right to observe the exterior rearview mirrors during driving and distract his attention, and reduce driving risks.

[0023] In one embodiment, the depth of field range of the telephoto camera module 100 is not less than 4m, and the distance from the conventional vehicle electronic rearview mirror to the rear of the car is about 4m. Therefore, the depth of field range of the telephoto camera module 100 is set to 4m to infinity. Further, the FOV setting range of the telephoto camera module 100 is 45°, the conventional lane width is about 3m, and the vehicle width is about 2m. Therefore, it can be seen that the remaining maximum distance between the lane and the adjacent lane is about 4m. Because the distance from the electronic rearview mirror to the rear of the car is about 4m, the ratio of the remaining maximum distance between the lane and the adjacent lane to the distance from the electronic rearview mirror to the rear of the car is tan45°, that is, the range that can be covered by the telephoto camera module 100 lens is 45°. Therefore, a larger visual range is provided for the driver.

[0024] Please refer again Figure 1 In one embodiment, the distance measurement module 200 includes a signal transmitter 210 and a signal receiver 220, and the signal transmitter 210 and the signal receiver 220 are arranged relatively parallel.

[0025] It should be noted that the signal transmitter 210 is used to transmit light, and the signal receiver 220 is used to receive the light that hits the external vehicle and bounces back. Preferably, the ranging module 200 adopts a TOF module. The TOF module has the advantages of accurate and fast measurement, can accurately detect objects in a short time, and is not affected by humidity, air pressure and temperature, and is more suitable for outdoor use.

[0026] Please refer again Figure 1 In one embodiment, a first mounting hole 310 and a second mounting hole 320 are provided at both ends of the PCB board 300. Furthermore, a first rubber strip 330 and a second rubber strip 340 are provided on the PCB board 300. The first rubber strip 330 is provided below the telephoto camera module 100, and the second rubber strip 340 is provided below the ranging module 200. With such a configuration, the electronic rearview mirror camera device 10 can be stably installed on the electronic rearview mirror, providing a more stable working environment.

[0027] Please refer again Figure 1 In one embodiment, the signal receiver 220 is provided with a plurality of capacitors 221 and a plurality of resistors 222, so that the signal receiver 220 is fully protected.

[0028] Embodiment 2:

[0029] In one embodiment, an electronic rearview mirror is also included, including the electronic rearview mirror camera device 10 of any one of Example 1. The electronic rearview mirror also includes a transparent shell, which is used to wrap the electronic rearview mirror camera device 10. Preferably, a waterproof film and a heating and defogger device are provided on the transparent shell.

[0030] It should be noted that the transparent shell of the electronic rearview mirror is provided to avoid blocking the field of view of the electronic rearview mirror camera device 10. A waterproof film and a heating and defogger device are provided on the transparent shell. This setting is to reduce the impact of rainy and foggy weather on the electronic rearview mirror camera device 10, provide the driver with a normal field of view, and avoid traffic accidents.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
