Problems solved by technology
Due to the large size of the cab and body of commercial vehicles, there are large blind spots. If there is no good comprehensive vision performance, it is easy to cause complaints from users in the actual use process, and even affect the driving safety of the vehicle.
In the process of commercial vehicle product development, it is difficult to quantify the subjective evaluation of comprehensive vision, and it is impossible to give designers clear target suggestions, and objective measurement data is urgently needed to support it.
[0003] Field of view measurement tool and measurement technology situation at present stage: patent document (CN202033196) is used for the visual field measurement device of the verification of visibility and windshield transparent area inside the car, its height is not adjustable, and versatility is not enough; Patent document (CN102967473A) is A driver's front field of view measurement device, which requires high precision in manufacturing, and requires daily maintenance and anti-rust, is not convenient to use; The angle related to the driver's field of vision has relatively complete functions, but its structure is relatively complicated, and it is installed on the seat, and the fixation is not firm enough, and there are hidden dangers of deviation in the benchmark test results; the above patent documents are based on the development of passenger cars, and are more suitable for Passenger cars; the patent document (CN205280377U) is based on the development of commercial vehicles, which can accurately simulate the driver's eye point and line of sight and realize the measurement of the front vision, but it does not cover the comprehensive vision of the whole vehicle. In addition, the seat needs to be disassembled during the measurement, which is less convenient Difference
[0004] In summary, none of the above-mentioned measuring devices has achieved comprehensive field of view measurement; there is room for improvement in the portability, ease of operation, and high versatility of the measuring device

The invention belongs to the commercial vehicle performance test field and especially relates to a suspended commercial-vehicle integrated visual field testing device. The device is attached to a vehicle window glass fixing device through a powerful suction disc. A suspension rod, a universal adjustment structure and the like are adjusted to determine that a position of a laser emitter is superposed with an eyespot position of a driver. A laser irradiator uniformly sweeps the dots along an edge of a visible area in front of a cab and the edge of sight glass, and tested ground light spots forma track curve according to an irradiation sequence. Each curve combination divides surrounding areas of a vehicle to form a visible area and a visual field blind area according to a visual field category, and a vehicle comprehensive visual field performance map is obtained after correction. In the invention, installation and dismounting are convenient, a high model matching degree is possessed, and the device is suitable for visual field measurement of various commercial vehicles. A commercial-vehicle integrated visual field measuring function is realized. In addition to a front visual field,visual-field visual range measurement of a front-view mirror, a main rear view mirror, a wide-angle external view mirror, a blind compensation mirror and other indirect visual field devices is added.
Description
Technical field [0001] The invention belongs to the field of commercial vehicle performance testing, and specifically is a suspension type commercial vehicle comprehensive visual field testing device. Background technique [0002] The comprehensive vision of commercial vehicles involves an important man-machine project of driving safety and riding comfort. Commercial vehicles have large blind spots due to the large size of the cab and body. If they do not have good comprehensive visual field performance, they will easily cause complaints from users during actual use and even affect the driving safety of the vehicle. In the process of commercial vehicle product development, it is difficult to quantify the subjective evaluation of the comprehensive vision, and designers cannot be given clear goals and suggestions. Objective measurement data is urgently needed for support. [0003] Current visual field measurement tools and measurement technology: Patent document (CN202033196) is a v...
