Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of vehicle parts inspection tools, and in particular, to a vehicle door panel inspection tool. Background Art

[0002] All sheet metal parts in automobiles are painted to prevent rust during use. Furthermore, electrophoresis coating is performed before painting to ensure good adhesion and adsorption stability for the subsequent paint. With the demand for lightweight vehicles, some parts may deform after undergoing multiple production processes, such as electrophoresis coating, and high-temperature electrophoresis baking. For example, a side-opening tailgate is a prone part to deformation. Therefore, after these processes, parts must be inspected to ensure factory quality.

[0003] In related technologies, the method for determining tailgate deformation is typically as follows: Before assembly in the welding shop, the tailgate undergoes blue light scanning or three-dimensional coordinate measurement to obtain a first set of data, which is then assembled on the vehicle body. The vehicle body then travels through a conveyor system to the paint shop entrance. After undergoing multiple processes such as electrophoresis and baking, the vehicle body is removed from the paint shop, removed, and sent to the welding shop. Blue light scanning or three-dimensional coordinate measurement is then performed again to obtain a second set of data. These two sets of data are compared to confirm whether the tailgate deformation is within a preset range.

[0004] During the above-mentioned back door inspection process, the back door needs to be disassembled for inspection. However, during the disassembly, assembly and transportation of the back door assembly, there are unpredictable variables, which can easily cause distortion of the measurement data. In addition, it is difficult to achieve online inspection of the back door, and the inspection efficiency is low. Utility Model Content

[0005] In view of this, an embodiment of the present application provides a vehicle door panel inspection fixture that can solve the problems of distorted tailgate inspection data and low inspection efficiency.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0008] A fixing seat, used for fixing the positioning component to the vehicle body;

[0009] A positioning component is provided on the fixing seat and is used to cooperate with a preset component on the vehicle body for positioning;

[0011] The vehicle door panel inspection fixture provided in the embodiment of the present application can, before electrophoresis coating, allow the staff to match the positioning component of the vehicle door panel inspection fixture with the preset component on the vehicle body to position the detection component. The detection component can correspond to the door panel to detect the deformation of the door panel surface to be tested through the measuring rod and obtain a first set of data. After electrophoresis coating, the staff can match the vehicle door panel inspection fixture with the preset component on the vehicle body again to perform a secondary detection of the deformation of the door panel surface to be tested through the detection component and obtain a second set of data. The second set of data is compared with the first set of data to obtain the deformation of the door panel before and after electrophoresis coating. When the deformation exceeds the preset value, the deformation of the door panel surface to be tested is difficult to meet the factory requirements, and the door panel needs to be trimmed or replaced.

[0012] Therefore, in the embodiment of the present application, the door panel can remain mounted on the vehicle body both before and after the electrophoretic coating process, allowing for online testing of the door panel. Furthermore, since the door panel does not need to be disassembled, transported, or reassembled during the testing process, the possibility of unpredictable variables during the disassembly, transportation, and reassembly processes affecting the accuracy of the test parameters can be reduced.

[0015] In a possible implementation of the present application, the display module includes a digital display screen, which is connected to the connecting end of the measuring rod, and the digital display screen is used to display the expansion and contraction amount generated by the contact between the measuring rod and the door panel.

[0016] In a possible implementation of the present application, the fixing base includes a magnetic base, a portion of the surface of the magnetic base is connected to the positioning component, and a portion of the surface of the magnetic base is in contact with the vehicle body. The magnetic base can release the magnetic field to adsorb the positioning component to the vehicle body, and the magnetic base can turn off the magnetic field to remove the positioning component from the vehicle body.

[0017] In a possible implementation of the present application, the positioning component includes a mounting plate, the magnetic base is detachably connected to the mounting plate, and the magnetic base is located between the mounting plate and the vehicle body.

[0018] In a possible implementation of the present application, the fixing base further includes a control panel, which is connected to the magnetic base and is used to control the opening or closing of the magnetic field of the magnetic base.

[0019] In a possible implementation of the present application, the magnetic base is provided with a visible surface facing the door panel, and the control panel is provided on the visible surface.

[0020] In a possible implementation of the present application, the positioning component further includes a first rod, one end of the first rod is connected to the mounting plate, and the other end of the first rod is used to support the detection assembly;

[0021] Wherein, the first rod body is provided with a mounting hole, the detection component is fixed to the mounting hole, and the measuring rod is passed through the mounting hole to be connected to the door panel.

[0041] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0045] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0046] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0047] An embodiment of the present application provides a vehicle door panel inspection fixture that can be used to detect the deformation of parts before and after processes such as painting and electrophoresis to ensure factory quality.

[0048] The parts to be tested may be parts of a vehicle. A vehicle may refer to a large car, a small car, a special-purpose vehicle, etc. For example, according to the vehicle model, the vehicle to which the parts are applied in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other vehicle models. A vehicle generally has wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate, thereby driving the vehicle.

[0049] It should be noted that the embodiments of this application do not limit the type of power source of the vehicle in which the components are used. For example, for fuel-powered vehicles, the power source may refer to a gasoline engine, a diesel engine, or other fuel-powered engine; for electric vehicles, the power source may refer to an electric motor; and for hybrid vehicles, the power source may refer to either an engine or an electric motor. For vehicles powered by other means, the power source may refer to the device that generates the power.

[0050] With the demand for lightweight vehicle bodies, some parts may deform after undergoing multiple production processes such as painting and electrophoresis, as well as high-temperature electrophoresis baking. Therefore, after painting and electrophoresis, parts need to be inspected to ensure they meet factory quality and appearance requirements.

[0051] In the embodiments of this application, the components to be inspected are not limited. For example, the component may be a vehicle door panel. For example, the door panel may be a front door, a rear door, or a side-opening back door. This application describes the back door as an example.

[0052] In related technologies, the method for determining tailgate deformation is typically as follows: Before assembly in the welding shop, the tailgate undergoes blue light scanning or three-dimensional coordinate measurement to obtain a first set of data, which is then assembled on the vehicle body. The vehicle body then travels through a conveyor system to the paint shop entrance. After undergoing multiple processes such as electrophoresis and baking, the vehicle body is removed from the paint shop, removed, and sent to the welding shop. Blue light scanning or three-dimensional coordinate measurement is then performed again to obtain a second set of data. These two sets of data are compared to confirm whether the tailgate deformation is within a preset range.

[0053] In the above-mentioned detection method, the tailgate needs to be disassembled to measure the data. However, during the disassembly, assembly and transportation of the tailgate assembly, there are unpredictable variables, which can easily cause distortion of the measurement data. In addition, it is difficult to achieve online detection of the tailgate, and the detection efficiency is low.

[0054] Based on the above technical problems, the vehicle door panel inspection fixture provided in the embodiment of the present application can, before electrophoresis coating, allow the staff to match the positioning component of the vehicle door panel inspection fixture with the preset component on the vehicle body to position the detection component. The detection component can correspond to the door panel to detect the deformation of the door panel surface to be tested through the measuring rod and obtain a first set of data. After electrophoresis coating, the staff can match the vehicle door panel inspection fixture with the preset component on the vehicle body again to perform a secondary detection of the deformation of the door panel surface to be tested through the detection component and obtain a second set of data. The second set of data is compared with the first set of data to obtain the deformation of the door panel before and after electrophoresis coating. When the deformation exceeds the preset value, the deformation of the door panel surface to be tested is difficult to meet the factory requirements, and the door panel needs to be trimmed or replaced.

[0055] Therefore, in the embodiment of the present application, the door panel can remain mounted on the vehicle body both before and after the electrophoretic coating process, allowing for online testing of the door panel. Furthermore, since the door panel does not need to be disassembled, transported, or reassembled during the testing process, the possibility of unpredictable variables during the disassembly, transportation, and reassembly processes affecting the accuracy of the test parameters can be reduced.

[0056] The vehicle door panel inspection fixture provided by the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0057] See also Figures 1 to 3 As shown, an embodiment of the present application provides a vehicle door panel inspection fixture 100 , comprising a detection assembly 110 , a positioning component 120 and a fixing seat 130 .

[0058] The fixing base 130 can be removably connected to the vehicle body. The positioning component 120 can be disposed on the fixing base 130 and used to cooperate with a pre-set component on the vehicle body for positioning. The pre-set component can be a structure of the vehicle body itself, or it can also be a structure that is removably connected to the vehicle body. The pre-set component and the positioning component 120 can be used to ensure that the surface to be tested of the door panel 300 is consistent before and after electrophoresis coating, thereby avoiding the problem of invalid test results caused by testing different surfaces of the door panel 300 twice.

[0059] The detection assembly 110 may be disposed on the positioning member 120. The detection assembly 110 may include a measuring rod 111 and a display module 112. The measuring rod 111 may be used to detect the deformation of the surface to be measured of the door panel 300. The display module 112 may be used to display the deformation parameters measured by the measuring rod 111.

[0060] In the embodiment of the present application, the vehicle door panel inspection fixture 100 can be fixed to the vehicle body 200 via the fixing base 130, so that the detection component 110 can be aligned with the surface to be tested of the door panel 300 and inspect the door panel 300. Therefore, before and after the electrophoretic coating process, the vehicle door inspection can be performed by installing the vehicle door panel inspection fixture 100, without having to disassemble, transport, and reassemble the door panel 300. This can reduce the possibility of unpredictable variables during the disassembly, transportation, and reassembly of the door panel 300, which may affect the accuracy of the inspection parameters.

[0061] Among them, the positioning component 120 and the fixing seat 130 can be used to fix the detection component 110 so that the measuring rod 111 of the detection component 110 can correspond to the surface to be tested of the door panel 300 to be tested, and the relative stability between the measuring rod 111 and the door panel 300 to be tested can be maintained to avoid the detection component 110 from shaking and affecting the accuracy of the detection results.

[0062] Furthermore, in the embodiment of the present application, the deformation amount of the surface to be measured of the door panel 300 can be detected by the measuring rod 111, and the detected accuracy parameters can be displayed through the display module 112. The staff can intuitively obtain the deformation amount of the door panel 300 through the accuracy parameters displayed on the display module 112.

[0063] It should be noted that the detection rod 111 can detect the door panel 300 in a contact manner. For example, the detection rod 111 can abut against the surface to be detected on the door panel 300 to measure the deformation of the door panel 300 based on the contact depth between the detection rod 111 and the surface to be detected on the door panel 300. Alternatively, the detection rod 111 can detect the door panel 300 in a non-contact manner. For example, the detection rod 111 can detect the deformation of the door panel 300 by using laser ranging, infrared ranging, or ultrasonic ranging.

[0064] The positioning member 120 may be provided on the vehicle body 200 . The positioning member 120 is used to connect the measuring rod 111 to the door panel 300 . The fixing base 130 is provided on the positioning member 120 , and the fixing base 130 may be used to fix the positioning member 120 to the vehicle body 200 .

[0065] For example, before electrophoresis coating, the staff can fix the vehicle door panel inspection fixture 100 to the vehicle body 200 through the positioning component 120 and the fixing seat 130, so as to detect the surface to be tested of the door panel 300 through the detection component 110. At this time, the display module 112 can display the surface parameters of the door panel 300 before electrophoresis coating. After the detection is completed, the staff can remove the vehicle door panel inspection fixture 100. The vehicle body 200 can reach the entrance of the paint shop through the conveying system to carry out processes such as electrophoresis coating and electrophoresis baking. After completing the above processes, the staff can fix the vehicle door panel inspection fixture 100 to the vehicle body 200 again through the positioning component 120 and the fixing seat 130, so as to perform a second detection of the surface to be tested of the door panel 300 through the detection component 110. At this time, the display module 112 can display the surface parameters of the door panel 300 after electrophoresis coating. The difference between the two measured surface parameters can be understood as the deformation amount of the door panel 300 after electrophoresis coating. When the deformation is within the preset range, the vehicle body 200 can enter the next process. When the deformation exceeds the preset range, the door panel 300 needs to be repaired or replaced.

[0066] In addition, it should be noted that in the embodiment of the present application, before and after the coating electrophoresis process, the measuring rod 111 of the detection component 110 has the same corresponding position on the door panel 300 to avoid the detection position deviation from affecting the accuracy of the detection result.

[0067] For example, when the vehicle door panel inspection fixture 100 is secured to the vehicle body 200, the surface to be tested on the door panel 300 may be a weak area of the door panel 300. A weak area may refer to an area on the door panel 300 that is susceptible to deformation. It is readily understood that after electrophoresis coating, if the deformation of the weak area on the door panel 300 is within a preset range, other areas of the door panel 300, due to their greater strength, are also less susceptible to deformation. Therefore, measuring the deformation of the weak area on the door panel 300 using the measuring rod 111 of the inspection assembly 110 can provide a reference for the deformation of other areas of the door panel 300.

[0068] Furthermore, in the embodiment of the present application, when the vehicle door panel inspection fixture 100 is installed on the vehicle body 200, the inspection component 110 may correspond to the outer surface of the back door. The outer surface of the back door may refer to the surface of the back door that a user can see when standing at the rear of the vehicle.

[0069] In some embodiments of the present application, reference is made to Figures 2 to 4 As shown, the detection assembly 110 may include a fixing sleeve 113. The fixing sleeve 113 may be used to cooperate with a preset structure on the positioning component 120 for positioning.

[0070] In the embodiment of the present application, the detection assembly 110 can be fixed to the positioning component 120 via the fixing sleeve 113. The preset structure and the positioning component 120 can be an integral structure, or the preset structure can be detachably connected to the positioning component 120.

[0071] It should be noted that the embodiment of the present application does not limit the connection method between the fixing sleeve 113 and the preset structure. The fixing sleeve 113 and the preset structure can be non-detachably connected, for example, by welding, crimping, or bonding, or they can be detachably connected, for example, by snap-fitting or screwing.

[0072] The fixing sleeve 113 can be connected to the display module 112. The measuring rod 111 is telescopically disposed in the fixing sleeve 113, and the measuring end 111a of the measuring rod 111 can pass through the end of the fixing sleeve 113 to form abutment with the surface to be measured of the door panel 300.

[0073] In the embodiment of the present application, the fixing sleeve 113 can be used to fix the measuring rod 111. The measuring end 111a of the measuring rod 111 can remain in contact with the surface to be measured of the door panel 300. Moreover, since the measuring rod 111 is telescopically connected to the fixing sleeve 113, when the door panel 300 is deformed, the measuring end 111a of the measuring rod 111 can extend or retract in the fixing sleeve 113 under the action of the surface to be measured of the door panel 300, so as to obtain the deformation amount of the door panel 300 through the extension and contraction amount of the measuring rod 111.

[0074] It should be noted that the expansion and contraction of the measuring rod 111 can be used to reflect the deformation of the door panel 300. If the difference in the expansion and contraction of the measuring rod 111 before and after electrophoretic coating is small, it can indicate that the deformation of the door panel 300 is small. Conversely, a large difference in the expansion and contraction of the measuring rod 111 can indicate that the deformation of the door panel 300 is large.

[0075] For example, after electrophoretic coating, if the door panel 300 is deformed outwardly, when the measuring end 111a of the measuring rod 111 is connected to the surface to be measured on the door panel 300, the outward convex deformation exerts a force on the measuring rod 111 to retract it back into the fixing sleeve 113. Similarly, if the door panel 300 is deformed inwardly, when the measuring end 111a of the measuring rod 111 is connected to the inwardly concave surface to be measured on the door panel 300, the measuring rod 111 can maintain the force against the outer surface of the door panel 300, allowing the measuring rod 111 to extend further out of the fixing sleeve 113.

[0076] In some embodiments of the present application, reference is made to Figure 4 As shown, the display module 112 may include a digital display screen 1121. The digital display screen 1121 is connected to the connecting end 111b of the measuring rod 111, and the digital display screen 1121 can be used to display the expansion and contraction amount generated by the contact between the measuring rod 111 and the door panel 300.

[0077] In this embodiment of the present application, the digital display 1121 can be used to directly display the expansion and contraction of the measuring rod 111, allowing the operator to intuitively understand the deformation of the door panel 300. The operator can determine the deformation of the area corresponding to the measuring rod 111 on the door panel 300 based on the difference in the expansion and contraction of the measuring rod 111 before and after electrophoresis coating.

[0078] The connecting end 111b of the measuring rod 111 can be used to fix the digital display 1121. It should be noted that the embodiment of the present application does not limit the connection method between the digital display 1121 and the connecting end 111b of the measuring rod 111. The connection method between the digital display 1121 and the connecting end 111b of the measuring rod 111 can be a fixed connection or a detachable connection.

[0079] In some embodiments of the present application, reference is made to Figure 3 and Figure 5 As shown, the fixing base 130 may include a magnetic base 131. A portion of the surface of the magnetic base 131 may be connected to the fixing bracket positioning component 120, and a portion of the surface of the magnetic base 131 may be in contact with the positioning component 120. The magnetic base 131 may release a magnetic field to attract the positioning component 120 to the vehicle body 200. The magnetic base 131 may also turn off the magnetic field to remove the positioning component 120 from the vehicle body 200.

[0080] In the embodiment of the present application, since the vehicle body 200 is typically a sheet metal part, when the magnetic base 131 releases its magnetic field, the magnetic base 131 can be adsorbed onto the vehicle body 200, thereby securing the positioning component 120 to the vehicle body 200. The release of the magnetic field by the magnetic base 131 maintains the reliability of the connection between the magnetic base 131 and the vehicle body 200, thereby maintaining the stability of the connection between the measuring rod 111 of the detection assembly 110 and the door panel 300, and reducing the possibility of shaking of the measuring rod 111, which could affect the accuracy of the detection results.

[0081] After the detection is completed, the magnetic base 131 can turn off the magnetic field, the magnetism of the magnetic base 131 disappears, and the magnetic base 131 can be separated from the vehicle body 200, so that the vehicle door panel inspection fixture 100 can be removed from the vehicle body 200.

[0082] It should be noted that, because the positioning component 120 can be fixedly connected to the vehicle body 200 via the magnetic base 131 in this embodiment of the present application, no operating tools are required during the installation or removal of the vehicle door panel inspection fixture 100. The installation and removal process of the vehicle door panel inspection fixture 100 in this embodiment of the present application is simple and convenient to operate, which helps improve inspection efficiency.

[0083] In some examples, an induction coil may be provided in the magnetic base 131. Powering the induction coil may release the magnetic field, while de-energizing the induction coil may deactivate the magnetic field.

[0084] On this basis, refer to Figure 3 As shown, in some embodiments of the present application, the positioning component 120 may include a mounting plate 121. The magnetic base 131 is detachably connected to the mounting plate 121. The magnetic base 131 may be located between the mounting plate 121 and the vehicle body 200.

[0085] In the embodiment of the present application, the positioning component 120 can be connected to the magnetic base 131 via the mounting plate 121. A larger contact area can be provided between the mounting plate 121 and the magnetic base 131 to improve the connection stability between the magnetic base 131 and the positioning component 120.

[0086] In some embodiments of the present application, reference is made to Figure 3 and Figure 5 As shown, the fixing base 130 may further include a control panel 132. The control panel 132 is connected to the magnetic base 131, and the control panel 132 is used to control the opening or closing of the magnetic field of the magnetic base 131.

[0087] In the embodiment of the present application, the staff can operate the control panel 132 to control the magnetic base 131 to release or close the magnetic field. The operation method is simple and convenient, which is conducive to improving the detection efficiency.

[0088] In some embodiments of the present application, reference is made to Figure 1 and Figure 2 As shown, the magnetic base 131 may be provided with a visible surface facing the door panel 300. The control panel 132 may be provided on the visible surface.

[0089] In the embodiment of the present application, since the detection assembly 110 corresponds to the door panel 300, when the door panel 300 is a rear door, a worker located in the rear door area can conveniently observe the accuracy parameters displayed on the display module 112. The visible surface of the magnetic base 131 faces the rear door, so by placing the control panel 132 on the visible surface of the magnetic base 131, the worker can easily operate the control panel 132.

[0090] In some examples, the present invention does not limit the structure of the control panel 132. For example, the control panel 132 can be a rotary switch. Forward rotation of the rotary switch can energize the coil within the magnetic base 131 to release the magnetic field, thereby achieving a fixed connection between the vehicle door panel inspection fixture 100 and the vehicle body 200. Reverse rotation of the rotary switch can de-energize the coil within the magnetic base 131 to deactivate the magnetic field, thereby allowing the vehicle door panel inspection fixture 100 to be removed from the vehicle body 200.

[0091] In some embodiments of the present application, reference is made to Figure 3 and Figure 6 As shown, the positioning component 120 may further include a first rod 122. One end of the first rod 122 may be connected to the mounting plate 121, and the other end of the first rod 122 may be used to support the detection assembly 110. The first rod 122 may be provided with a mounting hole 122a for the measuring rod 111 to pass through. The measuring rod 111 may be inserted into the mounting hole 122a to connect to the door panel 300.

[0092] In this embodiment of the present application, the first rod 122 can provide stable support for the detection assembly 110. The measuring end 111a of the measuring rod 111 of the detection assembly 110 can pass through the mounting hole 122a of the first rod 122 to abut against the surface to be measured of the door panel 300.

[0093] Part of the measuring rod 111 can be located between the first rod body 122 and the door panel 300 to detect the deformation of the surface to be measured of the door panel 300, and the display module 112 can be located on the side of the first rod body 122 facing away from the door panel 300. Therefore, the display module 112 can be less likely to occupy the space between the first rod body 122 and the door panel 300.

[0094] In some examples, the pre-set structure on the positioning member 120 can be a mounting hole 122a. The mounting hole 122a can be used to mount the detection assembly 110. The detection assembly 110 can be inserted into the mounting hole 122a via the fixing sleeve 113. The measuring rod 111 can be inserted through the mounting hole 122a to connect to the door panel 300.

[0095] In some embodiments of the present application, reference is made to Figure 3 and Figure 6 As shown, the positioning component 120 may further include a second rod 123. The first rod 122 and the second rod 123 may be located on either side of the fixing base 130. The first rod 122 and the second rod 123 may each be provided with a positioning member 124 that matches a preset component on the vehicle body 200.

[0096] In the embodiment of the present application, the positioning member 124 on the first rod 122 and the positioning member 124 on the second rod 123 can be used to limit the position of the positioning component 120 relative to the vehicle body 200, so as to prevent the detection component 110 on the positioning component 120 and the door panel 300 from being offset during the detection process, thereby affecting the accuracy of the detection.

[0097] In some examples, the positioning member 124 on the first rod 122 and the positioning member 124 on the second rod 123 can be connected to structures on the vehicle body 200 respectively.

[0098] For example, the water trough area of the vehicle body 200 is typically provided with a process hole. Therefore, the process hole in the water trough area can serve as a pre-set component for positioning the detection assembly 110. The positioning member 124 on the first rod 122 and the positioning member 124 on the second rod 123 can be inserted into the two process holes on the vehicle body 200, respectively, to prevent deflection between the positioning member 120 and the vehicle body 200. The magnetic base 131 can then release a magnetic field to securely connect the positioning member 120 to the vehicle body 200.

[0099] In the embodiment of the present application, the structure of the positioning member 124 is not limited. For example, the positioning member 124 can be a pin structure.

[0100] It should be noted that before and after electrophoretic coating, the positioning piece 124 on the first rod body 122 corresponds to the same process hole on the vehicle body 200, and the positioning piece 124 on the second rod body 123 corresponds to the same process hole on the vehicle body 200, so that the measuring rod 111 can correspond to the same position of the door panel 300, thereby maintaining the accuracy of the detection of the measuring rod 111.

[0101] Therefore, during the installation of the vehicle door panel inspection fixture 100 of the embodiment of the present application on the vehicle body 200, the positioning member 124 of the first rod body 122 and the positioning member 124 on the second rod body 123 can first be aligned with the two corresponding process holes on the vehicle body 200, and then the magnetic base 131 can be activated through the control panel 132 to release the magnetic field to fix the positioning member 120 on the vehicle body 200. Relative movement is not easy to occur between the positioning member 120 and the vehicle body 200, which is conducive to improving the detection accuracy of the measuring rod 111 on the door panel 300. After the first detection is completed, the magnetic field of the magnetic base 131 can be turned off through the control panel 132. At this time, the magnetic force between the magnetic base 131 and the vehicle body 200 is eliminated, and then the positioning member 124 on the first rod body 122 and the positioning member 124 on the second rod body 123 can be pulled out of the two process holes on the vehicle body 200.

[0102] The vehicle door panel inspection fixture 100 of the present embodiment is easy to install and remove, requiring no mounting structure or drilling holes on the vehicle body 200, nor the use of operating tools. This improves inspection efficiency. Furthermore, the display module 112 provides a clear and intuitive display of measurement results, facilitating batch inspections. This data can then be used to subsequently assess and predict deformation.

[0103] In some examples, the first rod 122 and the second rod 123 can be arranged side by side and spaced apart. The fixing base 130 can be located between the first rod 122 and the second rod 123. The first rod 122 and the mounting plate 121 can be connected by welding. The second rod 123 and the mounting plate 121 can also be connected by welding.

[0104] In some examples, a reinforcement portion 120 a may be provided between the first rod 122 and the mounting plate 121 , and a reinforcement portion 120 a may also be provided between the second rod 123 and the mounting plate 121 to improve the connection stability between the vehicle door panel gauge 100 and the vehicle body 200 .

[0105] In some examples, the positioning member 124 can be connected to the first rod 122 and the second rod 123 using a welding process.

[0106] In some embodiments of the present application, reference is made to Figure 6 As shown, the first rod body 122 may include a first cantilever 1221 and a second cantilever 1222. The first cantilever 1221 may be connected to the mounting plate 121. The second cantilever 1222 may be used to extend the detection assembly 110 so that the measuring rod 111 corresponds to the door panel 300.

[0107] In some examples, the positioning member 124 can be provided on the first cantilever 1221. The first cantilever 1221 and the second cantilever 1222 can be an integral structure.

[0108] In some examples, an angle may be formed between the first cantilever 1221 and the second cantilever 1222. Setting the angle may be used to align the measuring rod 111 of the detection assembly 110 with the surface to be detected on the door panel 300.

[0109] In the embodiment of the present application, the angle between the first cantilever 1221 and the second cantilever 1222 is not limited. The first cantilever 1221 and the second cantilever 1222 can satisfy the correspondence between the measuring rod 111 and the door panel 300.

[0110] Furthermore, in the embodiment of the present application, there is no limitation on the structure of the second cantilever 1222. The second cantilever 1222 may be, but is not limited to, a bent structure.
