HKC6109 series passenger check before the vision and the design of the exterior mirror positions

Within the boundaries; car door mirror right outside the front and back direction from the front axle centerline 2270mm, its outer edge away from the body at its widest point 240mm, within the boundaries shown in Figure 1 and Figure 2 that + car left outside L coordinates of the center mirror mirror (a 1700, a 1390,8 S0) i car door mirror right outside the center coordinates of Q (a 2270,1390 +850). 5. s the minimum angle of head rotation p and check according to ergonomic principles, the natural rotation of the head angle in the horizontal direction, left and right of the 4s. Eyes at the level of the natural rotation angle of left and right of the 30. . That is, when the target line of sight in the front left and right 3D. Range, the driver instead of just a natural rotation of the eyes, turning head. + As in the design of the vehicle left and right rear view mirror in the position of the set + 1 Zhang Deren: HKC6109 series of vision before the school bus and the exterior mirrors edge locations of 0395 limits the ellipse position, if line of sight 30. Natural visual target within the eye has not (available from behind the check verification), it must turn the head. Therefore, we turn to calculate the angle of the driver's eyes 3o. Circumstances, the head of the smallest rotation angle to be p and p checking whether the standards within. First of all, on the Ellipse in the eye to find the left eye from a recent column A recent point of N and the corresponding point of the right eye touched upon M, as in the two vertical connection and to identify the head center of rotation J, J point in the left and right eyes in the vertical connection at the rear 98.6mm, may J point coordinates (xJ eleven 970mm, Y 』eleven 736mm) can be seen from Figure 2, in the case of the head does not rotate,[link widoczny dla zalogowanych], connecting N points with the car left outside the door mirror mid-point of L, have the maximum visual angle of the left rear view mirror view; connection M point and the midpoint of cars right outside door mirror Q, get the right rearview mirror visual maximum angle of sight, seen from the chart are beyond the human eye's natural rotation angle. p angle is calculated as follows: a arctg [(yL-YJ) / (x】 A xL)] + arcsin.

Where: YL eleven 1390mm; Y 』a 736mm; l one by one 1700mm; xj eleven 970mm so, yL-YJ 1390 +736 one by one one by one 654mm; a xL one by one 970 one (a 1700) for a 730mm. Then: a arctg (a 654/730) + arcsin [77.4 /, Qiao Lili] a 3o. A 7.327 ≈ 7. Similarly, the right turning point of Bq as follows: a arctg (YQ-YJ) / (x 』a xQ) + arcsiD-____________________________E77.4 / (xJxQ). + (YQ-Y1)] a 30. Where: YQ a 1390mm; xQ one by one 2270mm. So,[link widoczny dla zalogowanych], YL-Yr a 1390 +736-2126 rom {xf-xL eleven 970 (a 2270) a 1300mm Pui 0: a arctg (2126/730) + arcsin [77.4/v/1300T2126] a 30. A 30.3399. ≈ 3o. The calculation that, when the driver eyes turn 30. ,[link widoczny dla zalogowanych], The head of the largest angle to the left of 7. , Right, is 30. Are the natural angle of the head 45. Within the ergonomic requirements. 4 Concluding remarks on the calculation and verification by, HKC6109 series passenger car windscreens and mirrors the design is reasonable, successful, ergonomic requirements. In use,[link widoczny dla zalogowanych], the users are very satisfied with this design, which will effectively promote the product sales.
