[0002] As a convenient means of transportation, cars have brought great convenience to people's lives. Car doors are one of the car parts that are most closely related to car users. The operating force and operating feeling of opening and closing directly affect the car user's impression of the quality of the car. At present, in order to improve the user experience, the doors of some car models can already achieve electric power assistance during the door opening and closing process.

[0003] After the car door is assembled on the final assembly line, it is also necessary to inspect the gap and surface difference between the car door and surrounding parts when opened or closed.

[0043] In the embodiment of the present invention, in the initial state: the distances between the first detection column 33 and the second detection column 421 and the housing assembly 1 are consistent, and at this time, the distance between the laser ranging sensor 32 and the second substrate 411 is a constant K;

[0044] On the premise that the position of the first detection column 33 remains unchanged, when it is necessary to move the second detection column 421 to select different points on the vehicle body surface to detect the flushness, the operation steps are as follows: control the rotation of the threaded rod 422 by the knob 424, and the rotating threaded rod 422 controls the second detection column 421 to move along the linear guide rail 412 by threaded connection with the nut block 423, and then controls the shell assembly 1 to move toward the door sheet metal and the vehicle body. When the shell assembly 1 is in contact with the door sheet metal surface, the distance between the laser ranging sensor 32 and the second substrate 411 is H, and the integrated circuit board in the size display module 2 receives and calculates the flushness △H=HK, and the flushness data is displayed on the electronic display screen 22.

[0045] See also Figure 1 , Figure 5 and Fig.12 In one embodiment of the present invention, the first size detection component 3 also includes a square rod 35 and a second axle pin 38, one end of the square rod 35 is fixedly connected to the first substrate 31, the second axle pin 38 is fixedly connected to the other end of the square rod 35, and the detection bent rod 37 is rotatably connected to the second axle pin 38.

[0046] See also Figure 1 and Figure 8Furthermore, the surface of the shell assembly 1 is provided with a first linear hole 11, a second linear hole 12, a third linear hole 14, a hand-held area 16, a square hole and a round hole, the second detection column 421 is in sliding contact with the first linear hole 11, the first detection plug 36 and the second detection plug 414 are in sliding contact with the second linear hole 12, the threaded rod 422 is in sliding contact with the third linear hole 14 near the knob 424, the square rod 35 is in sliding contact with the square hole, and the first detection column 33 is in sliding contact with the round hole.

[0047] In the embodiment of the present invention, when the detection bent rod 37 is used, it is rotated 90 degrees with the second axle pin 38 as the axis, so that the detection bent rod 37 and the square rod 35 are in a straight line, and the distance between the end of the detection bent rod 37 and the surface of the housing assembly 1 or the bottom bracket 15 is an integer value.

[0048] Working principle: When the detection device is needed to detect the surface difference between the door sheet metal and the body, press the mode selection key 24 to select the surface difference detection mode. Fig.10 First, place the first detection column 33 and the second detection column 421 at the corresponding positions of the door sheet metal and the vehicle body respectively, and then control the housing assembly 1 to move toward the door sheet metal and the vehicle body through the hand-held area 16. When the housing assembly 1 is in contact with the surface of the door sheet metal, the distance between the laser ranging sensor 32 and the second substrate 411 is H. The integrated circuit board in the size display module 2 receives and calculates the face difference △H=HK. The face difference data is displayed on the electronic display screen 22. When a rubber pad is provided at the end of the first detection column 33, the thickness D of the rubber pad should be calculated.

[0049] In addition, under the premise that the position of the first detection column 33 remains unchanged, when it is necessary to move the second detection column 421 to select different points on the vehicle body surface to detect the face difference, the operation steps are as follows: control the rotation of the threaded rod 422 by the knob 424, and the rotating threaded rod 422 controls the second detection column 421 to move along the linear guide rail 412 by threaded connection with the nut block 423, and then measure the face difference of another point according to the operation method of face difference detection.

[0050] When the detection device is required to detect the gap between the door sheet metal and the vehicle body, press the mode selection key 24 to select the gap detection mode. Fig.11First, press the first detection column 33 and the second detection column 421 by hand at the same time to adjust the gap between the first detection plug 36 and the second detection plug 414 to the minimum value, and then put the first detection plug 36 and the second detection plug 414 between the door sheet metal and the body at the same time, and then release the first detection column 33 and the second detection column 421. At this time, the elastic force of the first spring 34 and the second spring 413 is used to drive the first detection plug 36 and the second detection plug 414 to move in opposite directions, until the first detection plug 36 and the second detection plug 414 are respectively attached to the door sheet metal and the body, the distance S between the laser ranging sensor 32 and the second substrate 411 is the gap value between the door sheet metal and the body.

[0051] When the detection device is required to detect the gap between the door guard plate and the side panel, press the mode selection key 24 to select the hidden position gap detection mode. Fig.12 First, the bottom bracket 15 is clamped or sleeved on the top of the side outer panel. Since the distance between the detection bent rod 37 and the surface of the bottom bracket 15 (the side close to the housing assembly 1) is a constant k, when the bottom bracket 15 is in contact with the top of the side outer panel, the distance between the detection bent rod 37 and the top of the side outer panel is k. Then, the door is closed. The closed door moves the detection bent rod 37, the first substrate 31 and the first detection column 33 through the guard plate. At this time, the distance between the laser ranging sensor 32 and the second substrate 411 is X1, and the distance moved by the detection bent rod 37 is X2=K-X1. Therefore, the gap △X between the door guard plate and the side outer panel is k-X2.

[0052] In summary, by utilizing the structural design in which the shell assembly 1, the size display module 2, the first size detection component 3 and the second size detection component 4 cooperate with each other, and only using one laser ranging sensor 32 as a measuring element, not only can the first detection column 33 and the second detection column 421 be used to detect the surface difference between the door sheet metal and the body at different positions, but the first detection plug 36 and the second detection plug 414 can also be used to detect the gap between the door sheet metal and the body. In addition, the detection bent rod 37 can also be used to detect the gap between the door guard plate and the side outer panel. It is particularly suitable for workers on the automobile assembly line to detect the gap matching size between the door and surrounding parts from both sides of the automobile, and has the characteristics of clever structural matching, diverse uses, strong practicality and easy use.
