Description

  The present invention relates to a head-up display device for a drive recorder, and in particular, an integrated device that combines a drive recorder and a head-up display function. The present invention relates to a head-up display device for a drive recorder that allows the driver to view the drive information and the road scenery at the same time and adjust the angle of the front video camera lens as necessary, thus improving the safety of driving.

More and more information is provided in the car. By reading the information during driving, the line of sight leaves the road, creating a dangerous situation. In order to solve this drawback, an automobile head-up display has been developed. Thereby, the driver can pay attention to the road conditions ahead when reading the information. In particular, a head-up display that forms a virtual image using a concave mirror can enlarge the display area and provide a distance between the display image and the driver's eyes.
Usually, it is 2m or more, so when the driver watches the display information, the focal length of the line of sight and the focal length of the line of sight watching the road situation are close, and the driver pays attention to the road situation at the same time when reading the information. be able to. In this way, the danger during traveling can be greatly reduced.

Accidents can occur when driving a car. In the event of an accident, it is important to clarify your responsibilities and the fact of the other party's violation. As a result, sales of drive recorders continue to grow.
The drive automatic recorder was invented in Germany in 1925. The name “drive automatic recorder” is an evolution of the two letters German (TACHOMETER) and recording (GRAPHIK).
The initial drive recorder was a mechanical paper board type, and it was able to record the working time contents of information such as driving time, working time, rest time, and instantaneous speed of two drivers.
In the 1970s, electronic paperboard molds were developed, which were equipped with electronic equipment such as display screens, printers, magnetic cards, and card readers. However, with the development of technology, paperboard drive recorders have been replaced by drive recorder devices similar to airplane black boxes.

The drive recorders currently on the market can not be called drive recorders, but can only be called drive photography equipment. According to industry estimates, 100,000 units were sold last year, but the relevant agencies stated: Although the user-installed drive recorder equipment can be evidence of an accident, it does not have an absolute legal effect, so the determination of responsibility attribution is still subject to police appraisal.
According to the relevant organizations, the “drive recorder” in the law is forcibly attached to buses and sightseeing buses, and records information such as driving and stopping times, speed changes, etc., to judge safe driving of large passenger cars. Say something to rely on. In other words, in general accident site processing, the drive recording equipment is only proof of the statement, and it has no absolute legal effect.

In recent years, the operation technology of drive recorders has been widespread. As for head-up displays, the use of aircraft is spreading to automobiles. Related technologies include Patent Literature 1, Patent Literature 2, Patent Literature 3, Patent Literature 4, Patent Literature 5, Patent Literature 6, Patent Literature 7, Patent Literature 8, and the like. In these, a technology in which a drive recorder device and a head-up display device are integrally coupled is disclosed, and a technology of a head-up display articulated imaging device is also disclosed, but there are the following drawbacks in use.
1. Patent Document 1 is taken as an example. Although it discloses a technique for integrally combining a drive recorder device and a head-up display device, since it is mounted on a dashboard, there is a visual drop in the image reflected by the reflector and the scenery of the road ahead. For this reason, since the driver's line of sight when viewing relevant information is away from the road situation, there is still some danger.
2. Patent Document 2 is taken as an example. Although it discloses the technology of a head-up display connected photographing device, the head-up display and the photographing device occupy a limited space in the vehicle because they are two independent devices. In addition, there is inconvenience of wiring connection between the two, and the cost of deployment purchase is also increased.

(CM). The reflector A uses a concave mirror to enlarge virtual image formation. The principle of virtual image imaging is through concave mirror imaging. (Concave mirror imaging formula: formula: 1 / p + 1 / q = 1 / f, f: focal length, q: object distance, p: image distance)
In general, the magnification ratio enlarges the virtual image, and at the same ratio, the distance of the virtual image is increased by about 4 to 6 times. Therefore, the user can see in the best condition, and the user feels dizzy if the enlargement magnification is excessive. Therefore, in the virtual image formation, the distance from the driving eyeball must be 2 meters or more. Imaging is required to be about 1.2 meters or more behind the reflector, and the image projected by the display module 3 (HUD IMAGE) is reflected and enlarged so that the visual distance is at least 250 centimeters (CM). This distance is exactly the visual distance required to overlap the image with the road scenery seen through the front, and brings the focal distance of the driver's line of sight closer to the visual line focal distance where the road condition is observed. Therefore, when the driver reads the information, the driver can pay attention to the road condition at the same time, and the danger of driving is greatly reduced. In the conventional head-up display, there is no visual difference between the image and the road scenery. The problem that a head is generated can be solved.

  In summary, the head-up display device of the drive recorder of the present invention superimposes the virtual image reflected by the reflector and the scenery of the road ahead so that the driver can simultaneously view the drive information and the road scenery. In addition, the angle of the front video camera lens can be adjusted as necessary, thus increasing the safety of traveling, thereby effectively solving the problems existing in the prior art.
