Problems solved by technology
The existing detection tooling such as figure 1 , because the existing detection and measurement tooling is sleeve-type, it can only correspond to a point on the column of the bus, and can only measure the deformation of a point on the corresponding column
The deformation of other points on the column cannot be obtained, and the measurement effect is not accurate

Embodiment Construction
[0016] like figure 1 As shown, the device for detecting the deformation of the passenger car column of the present invention includes a measuring plate 1 and a sliding needle 2, and the sliding needle 2 is linear and vertically arranged in the length direction of the side measuring plate. The sliding needle 2 can slide to the other side of the measuring plate by external force on the measuring plate 1, but the sliding needle 2 cannot automatically move or fall off the measuring plate during the measurement process.
[0017] like figure 2 It is another embodiment of the present invention. When the measuring board is a plastic board, holes must be punched in the plastic board. Since the board has hardness and no elasticity, when the hole diameter is larger than the diameter of the sliding needle, the sliding needle is installed on it and moves easily. In order for the sliding needle to be used on such a measuring plate, the diameter of the sliding needle must be the same as th...

The invention discloses a device for detecting deformation amount of a stand column in a passenger car rollover experiment. The device comprises a measuring plate and a large amount of sliding needles capable of moving on the measuring plate, wherein the sliding needles are linearly and vertically arranged on measuring plate in the length direction. The device disclosed by the invention has the beneficial effects that: the deformation of the stand column of a passenger car can be detected in one step, the deformation degree of the stand column can be measured by means of the movement of the sliding needles so that the deformation amount of the stand column of the passenger car is easily observed, and the device has the advantages of much acquired data, high measurement precision, simple structure and easiness for operation.
Description
Technical field [0001] The invention relates to a passenger car detection device, in particular to a detection device for the deformation of a passenger car column after the passenger car is subjected to a rollover test. Background technique [0002] Since the passenger car is related to the life safety of the passengers, the overturning test can be used to complete the assessment of the strength of the upper structure of the bus. The test objects include the waist beam, the top beam and the column of the bus. The part that contributes the most to the strength of the upper structure is the column. There is a tool for detecting the deformation of the column of the passenger car after the overturning test, which can measure the deformation of the column of the passenger car during the test process, and by measuring the deformation amount, it is possible to know whether the passenger car occupants have enough living space during the test process. Existing inspection tooling suc...
