Embodiment Construction
[0022] The present invention will be further described below in conjunction with accompanying drawing.
[0023] Such as figure 2 As shown, in this embodiment, the flexible lower leg module includes a flexible lower leg 3 , a flexible lower leg bone 14 and an upper bracket 2 . The upper bracket 2 is in the shape of a "door" as a whole, which includes an upper bracket beam and two upper bracket side beams 9 . The flexible lower leg bone 14 is fixedly connected to the upper surface of the flexible lower leg 3 , and the upper bracket 2 is fixedly connected to the flexible lower leg bone 14 through the installation bolt 6 .
[0024] Such as Figure 3 to Figure 5 The shown bracket angle on the flexible calf includes an angle body, which is integrally formed, including a positioning part, and a measuring part fixedly arranged on the left side of the positioning part. Wherein, the left side of the positioning portion has an auxiliary installation positioning surface 12 that can be...

The invention discloses a flexible shank upper bracket angle ruler, and the angle ruler comprises an angle ruler body which comprises a positioning part and a measurement part which is fixedly disposed on the left side surface of the positioning part. The left side surface of the positioning part is provided with an auxiliary installation positioning surface which can be attached to an upper bracket side beam at the left side. The measurement part is provided with a lower measurement surface which can be attached to the upper surface of a flexible shank bone below, and an upper measurement surface which can be attacked to the lower surface of an upper bracket beam at the upper side. Moreover, the inclined angle between the lower measurement surface and the upper measurement surface is equal to the angle between the upper surface of the upper bracket and the upper surface of the flexible shank when the upper bracket and the flexible shank are installed in place. The invention also discloses an upper bracket angle inspection method and an adjustment method. According to the invention, the angle ruler and method can achieve the quick inspection and adjustment of the angle of the upperbracket, and meet the requirements of test precision.
Description
technical field [0001] The invention belongs to the technical field of pedestrian protection flexible calf test, and in particular relates to an upper bracket angle gauge for flexible lower legs, an inspection method and an adjustment method for the angle of the upper bracket. Background technique [0002] When preparing for the pedestrian protection test, if figure 1 As shown in Fig. 1, the launching tool 4 is first connected with the power device 1, and then the well-prepared flexible calf module is hung on the front end of the tool. During the test, the power equipment 1 pushes the flexible lower leg module and the launching tool 4 forward together. After reaching a certain speed, the launching tooling stops, the flexible lower leg module is separated from the launching tooling 1, and then the flexible lower leg module flies freely for a certain distance before contacting the test vehicle Collision. After the flexible calf module collides with the vehicle, it will rebou...
