[0047] This utility model provides a device for detecting the inner gap of the tailgate of a car. For example... Figure 4As shown, the car trunk includes a fixedly mounted trunk side panel 10 and an openable trunk lid 20. The outer edge of the trunk side panel 10 is provided with a sealing strip mounting portion 101 for fixing and installing a sealing strip. Before installing the sealing strip, the trunk lid clearance detection device according to this application is used to detect the trunk lid clearance between the sealing strip mounting portion 101 on the trunk side panel 10 and the trunk lid 20 after the trunk lid 20 is closed.

[0048] like Figures 1 to 3 As shown, the tailgate inner gap detection device of this application includes a positioning clamp 30, a vernier caliper 40, and a detection head 50. The positioning clamp 30 is detachably engaged with the sealing strip mounting portion 101 of the rear trunk side panel 10, thereby detachably mounting the entire tailgate inner gap detection device onto the sealing strip mounting portion 101 of the rear trunk side panel 10. The vernier caliper 40 includes a slidingly engaged main scale portion 41 and a sliding scale portion 42. The sliding scale portion 42 is fixedly connected to the positioning clamp 30. The detection head 50 is movably mounted on the positioning clamp 30 along the sliding direction of the sliding scale portion 42 and is fixedly connected to the main scale portion 41. At least a portion of the detection head 50 extends out of the positioning clamp 30, and the extended portion of the detection head 50 is used to contact the rear trunk cover 20.

[0049] When measuring the rear door clearance, with the rear door cover 20 open, the positioning clamp 30 is installed on the sealing strip mounting part 101 of the rear door side panel 10, and the positioning clamp 30 and the sliding ruler part 42 remain stationary. Then, the rear door cover 20 is closed, and the rear door cover 20 acts on the detection head 50, causing the detection head 50 to move relative to the positioning clamp 30 and the sliding ruler part 42. The main ruler part 41 moves along with the detection head 50 relative to the positioning clamp 30 and the sliding ruler part 42, thereby creating a relative displacement between the main ruler part 41 and the sliding ruler part 42. This allows for the detection of the rear door clearance between the rear door cover 20 and the sealing strip mounting part 101 after the rear door cover 20 is closed. Once the detected rear door clearance is within the allowable range, the subsequent sealing strip installation is performed. This application offers high detection accuracy and only requires the installation of the positioning clamp 30, making operation convenient and improving detection efficiency. Furthermore, the positioning clamp 30 in this application can be repeatedly installed and removed from the sealing strip mounting part 101 of the rear trunk side panel 10, and the measurement repeatability and reproducibility are both good.

[0050] Furthermore, the preferred structure of the positioning fixture 30 is as follows: Figures 1 to 3As shown, the positioning fixture 30 includes a fixture body 31, a fixture positioning block 32 fixed to the fixture body 31, a snap-fit ​​groove 33 formed between the fixture body 31 and the fixture positioning block 32, a fastening connecting block 34, and a fastening bolt 35. The snap-fit ​​groove 33 is used to accommodate the sealing strip mounting part 101 of the rear box side panel 10. The fastening connecting block 34 is installed on the fixture body 31 by the fastening bolt 35. The fixture body 31 has a fastening hole 311 for accommodating the fastening bolt 35. The fastening hole 311 communicates with the snap-fit ​​groove 33 and allows the end of the fastening bolt 35 to extend into the snap-fit ​​groove 33. The fixture body 31, the fixture positioning block 32, and the fastening connecting block 34 all have clearance grooves 36 for accommodating the detection head 50. The sliding ruler part 42 is fixed to the fixture body 31 by screws. The width of the snap-fit ​​groove 33 is greater than the thickness of the sealing strip mounting part 101, so that the positioning clamp 30 can be easily snapped onto the sealing strip mounting part 101. After snapping, tighten the fastening bolt 35 until the fastening bolt 35 protrudes from the fastening hole 311 and abuts against the sealing strip mounting part 101, thereby fixing the positioning clamp 30 as a whole onto the sealing strip mounting part 101. After the test is completed, loosen the fastening bolt 35 to release its abutment against the sealing strip mounting part 101, and then the positioning clamp 30 can be removed from the sealing strip mounting part 101.

[0051] Furthermore, such as Figures 1 to 3 As shown, the clamp positioning block 32 is L-shaped. The clamp positioning block 32 includes a horizontally extending fixing part 321 and a vertically downward extending locking and limiting part 322 from the end of the fixing part 321. The fixing part 321 is fixed to the top of the clamp body 31 by screws. The locking and limiting part 322 is distributed on the outer side of the clamp body 31. The locking groove 33 is formed between the locking and limiting part 322 and the clamp body 31.

[0052] Furthermore, such as Figures 1 to 3 As shown, the fastening connecting block 34 is T-shaped. The fastening connecting block 34 includes a connecting block body 341 and a connecting block positioning part 342 extending horizontally from the connecting block body 341. The connecting block body 341 is distributed on the outer side of the clamp body 31 and is connected to the clamp body 31 by fastening bolts 35. The connecting block positioning part 342 is inserted into the clearance groove 36 of the clamp body 31 and is positioned and engaged with the clearance groove 36 of the clamp body 31.

[0053] Preferably, such as Figures 1 to 3 As shown, a spring 37 is fitted onto the fastening bolt 35, and the spring 37 abuts against the head of the fastening bolt 35 and the connecting block body 341, facilitating the unscrewing of the fastening bolt 35. A mounting positioning groove 312 is provided at the lower end of the clamp body 31. The upper end of the sliding ruler part 42 is accommodated in the mounting positioning groove 312 and contacts and engages with the groove wall surface of the mounting positioning groove 312, facilitating the fixed installation of the sliding ruler part 42 within the clamp body 31.

[0054] Furthermore, the connection structure between the main scale section 41 and the detection head 50 is preferably as follows: Figures 1 to 3 As shown, the back door inner gap detection device also includes a sliding connecting block 60. The sliding connecting block 60 includes a ruler end connecting part 61 and a detection end connecting part 62 that bends upward from the ruler end connecting part 61. The ruler end connecting part 61 is a flat plate structure and is fixed to the main ruler part 41 by screws. The detection head 50 is a column component that extends vertically. The lower end of the detection head 50 is fixed to the top of the detection end connecting part 62. A portion of the detection end connecting part 62 is slidably accommodated in the clearance groove 36 of the clamp body 31. The sliding engagement between the detection end connecting part 62 and the clearance groove 36 ensures the stability of the movement of the detection head 50 and improves the detection accuracy. In addition, the threaded connection between the detection head 50 and the detection end connecting part 62 allows adjustment of the extension height of the detection head 50 from the positioning clamp 30, making it suitable for different detection applications.

[0055] In summary, this application can efficiently and accurately detect the internal gap of the tailgate, and has good measurement repeatability and reproducibility, ultimately effectively improving the quality of the car trunk.

[0056] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0057] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
