[0033] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0034] like Figures 1 to 3 As shown, the utility model provides a device for detecting the accuracy of the installation surface of the sealing strip of a car trunk lid, comprising a connecting seat 3, a pressure sensor 12 is connected to the connecting seat 3, and the pressure sensor 12 has a detection head 13;

[0035] When the connecting seat 3 is positioned and connected with the automobile main inspection fixture 1, the automobile trunk lid 2 is closed, and the detection head 13 is against the sealing strip installation surface 14 of the automobile trunk lid 2; the pressure sensor 12 detects the pressure applied by the sealing strip installation surface 14 of the automobile trunk lid 2 on the detection head 13.

[0036] In a device for detecting the accuracy of the mounting surface of a sealing strip of a car trunk lid of the utility model, a connecting seat 3 is used to positionally connect with a main inspection fixture 1 of a car, and a pressure sensor 12 on the connecting seat 3 is used to perform contact detection on the position error of the mounting surface 14 of the sealing strip of the car trunk lid 2. According to the pressure detected by the pressure sensor 12, it can be determined whether the error of the mounting surface 14 of the sealing strip of the car trunk lid is out of range. After the connecting seat 3 and the pressure sensor 12 are installed, after the detection of one mounting surface 14 of the sealing strip of the trunk lid is completed, the trunk lid is removed and another trunk lid is installed for detection, and the detection can be repeated. This detection method is simple and convenient, and the detection efficiency is high.

[0037] The utility model is a device for detecting the accuracy of the installation surface of the sealing strip of the trunk lid of an automobile. The device can conveniently detect the position error of the installation surface 14 of the sealing strip of the trunk lid of an automobile. In order to facilitate the detection, the pressure sensor 12 has an alarm device, which can send out an alarm signal when detecting unqualified products, so that the detection personnel can timely understand the detection results. Specifically, the pressure sensor 12 has a preset qualified pressure value range of P1 to P2. When the pressure value detected by the pressure sensor 12 is within the range of P1 to P2, the alarm device on the pressure sensor 12 does not send out an alarm signal. When the pressure value detected by the pressure sensor 12 exceeds the range of P1 to P2, the alarm device of the pressure sensor 12 sends out an alarm signal. As a preferred embodiment, the alarm device is an alarm lamp or a generator. The alarm device of the pressure sensor 12 can be used, or an external alarm device can be used. The pressure sensor 12 is connected to the alarm device signal. When the pressure detected by the pressure sensor 12 exceeds the standard, the alarm device sends out an alarm signal according to the pressure signal detected by the sensor.

[0038] In a device for detecting the accuracy of a trunk lid sealing strip installation surface of an automobile of the utility model, a pressure sensor 12 is used to detect the pressure of a trunk lid sealing strip installation surface 14 pressed on a detection head 13 to detect the position error of the trunk lid sealing strip installation surface 14. The detection head 13 of the pressure sensor 12 can be extended and retracted. If the pressure detected by the pressure sensor 12 is less than P1, it means that the distance between the trunk lid sealing strip installation surface 14 and the trunk opening is too large, and the compression amount of the sealing strip will be insufficient after the sealing strip is installed in the future, resulting in a poor seal; if the pressure detected by the pressure sensor 12 is greater than P2, it means that the distance between the trunk lid sealing strip installation surface 14 and the trunk opening is too small, and the compression amount of the sealing strip will be excessive after the sealing strip is installed in the future, and the sealing strip is more likely to be damaged by pressure, resulting in a shorter service life.

[0039] In order to enable the pressure sensor 12 to accurately detect the error of the sealing strip installation surface 14 of the car trunk lid 2, the connecting seat 3 needs to enable the pressure sensor 12 to be accurately positioned on the car main inspection fixture 1, and the connecting seat 3 needs to be accurately positioned on the car main inspection fixture 1. The pressure sensor 12 needs to be accurately positioned on the connecting seat 3. This positioning can be achieved through structural design. The positioning of the connecting seat 3 and the car main inspection fixture 1 can be positioned by a positioning method of two pins on one side. For details, please refer to Figures 1 to 3 The connection seat 3 has a positioning surface 4, and the positioning surface 4 is used to dock with the positioning plate 5 on the main automobile inspection fixture 1. The positioning plate 5 is connected to the main automobile inspection fixture 1. The positioning plate 5 is provided with two positioning holes 6 and a threaded hole 15. The connection seat 3 is provided with two positioning pins 7 and a connecting hole 8. The positioning pins 7 are used to connect the positioning holes 6, and the connecting hole 8 is used to install the locking screw 9; when the two positioning pins 7 are respectively inserted into the two positioning holes 6, the connecting hole 8 is aligned with the threaded hole 15, and the locking screw 9 is passed through the connecting hole 8 and screwed into the threaded hole 15 to lock the connection seat 3 on the main automobile inspection fixture 1; at this time, the detection head 13 can be against the sealing strip installation surface 14 of the automobile trunk lid 2. Of course, the specific structure and positioning method of the connection seat 3 can also be adjusted according to the conditions of the spatial structure. These can be achieved through structural design and are not listed in detail here.

[0040] In order to facilitate the installation of the pressure sensor 12, as shown in FIG. Figure 2 and Figure 3 As shown, the connection seat 3 is provided with an adjusting screw hole 10, and the pressure sensor 12 has an external threaded connection portion 11, which is connected to the adjusting screw hole 10. In order to position the end of the detection head 13 of the pressure sensor 12 relative to the connection seat 3, a step surface is further provided at the root of the thread on the external threaded connection portion 11 of the pressure sensor 12. When the external threaded connection portion 11 of the pressure sensor 12 is tightened in the adjusting screw hole 10, the step surface is pressed against the connection seat 3.

[0041] The sealing strip on the trunk lid of the car is in a large closed ring shape. To ensure good sealing performance of the trunk lid, each section of the sealing strip mounting surface 14 needs to have good accuracy. In order to accurately detect the accuracy of the sealing strip mounting surface 14 of the trunk lid 2 of the car, the trunk opening of the car main inspection fixture 1 is equipped with multiple connecting seats 3 and pressure sensors 12 to detect multiple points of the sealing strip mounting surface 14 of the trunk lid 2 of the car to control the accuracy of the sealing strip mounting surface 14 of the trunk lid 2 of the car.

[0042] Modern automobile manufacturing has a high degree of automation and intelligence. The detection data needs to be accurately and conveniently saved and recorded for subsequent tracing and analysis. In order to facilitate detection and data recording, the pressure sensor 12 is connected to the host computer signal, and the host computer receives the pressure value signal transmitted by the pressure sensor 12 and records and stores it.

[0043] Based on the technical solutions of the above embodiments, a device for detecting the installation surface accuracy of a car trunk lid sealing strip of the utility model can conveniently detect the accuracy of the installation surface of a car trunk lid sealing strip. The detection method is simple and convenient, the detection accuracy is high, and the detection can be repeated, with high detection efficiency.

[0044] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
