Rearview mirror inspection tool

Abstract

This disclosure provides a rearview mirror fixture, belonging to the field of fixture technology. The rearview mirror fixture includes a base, a first simulation body, and a second simulation body. The first simulation body is fixed to the base by a first column and has a through hole. The second simulation body includes a detachably connected first sub-simulation body and a second sub-simulation body, with the first sub-simulation body fixed to the base by a second column. The first sub-simulation body has a main positioning hole and a first positioning half-hole, and the second sub-simulation body has a second positioning half-hole, which together form a secondary positioning hole. The main positioning hole and the secondary positioning hole are opposite to the through hole, and are used to connect the main positioning pin and the secondary positioning pin of the rearview mirror, respectively. When removing the rearview mirror from the rearview mirror fixture, the first sub-simulation body and the second simulation body are separated, causing the secondary positioning hole to separate into two parts, thereby preventing the secondary positioning pin from being damaged by the secondary positioning hole. This also improves the ease of operation when removing the rearview mirror.

Description

Technical Field

[0001] This disclosure relates to the field of inspection tool technology, and in particular to a rearview mirror inspection tool. Background Technology

[0002] As an important decorative component of a car's exterior, the quality of automotive rearview mirrors is primarily assessed through the development of rearview mirror inspection fixtures. To be considered a qualified and usable fixture, its development must meet several key functionalities: first, the fixture's own precision must meet standards; second, the fixture must be easy for personnel to operate; third, the inspection content for the parts must be complete and comprehensive; and fourth, the parts should be easy to assemble and disassemble on the fixture, with stable positioning, among other things.

[0003] In related technologies, the installation and positioning method of automotive exterior rearview mirrors on rearview mirror fixtures is usually the same as the installation and positioning method on the complete vehicle. When assembling automotive exterior rearview mirrors on a complete vehicle, it is often completed by a single employee. To facilitate the employee's operation, a reverse-clamp structure is made on the secondary locating pin of the exterior rearview mirror. This reverse-clamp structure mainly serves as a pre-attachment mechanism to facilitate employee operation. Existing rearview mirror fixture solutions completely simulate the assembly method of rearview mirrors on the complete vehicle; that is, after the rearview mirror is installed on the fixture, the reverse-clamp structure of the secondary locating pin is pre-attached to the secondary locating hole of the rearview mirror fixture.

[0004] However, the rearview mirror fixtures in related technologies can hinder the removal of the rearview mirror after inspection. If the rearview mirror is forcibly removed, the secondary positioning hole may damage the barb structure of the secondary positioning pin. Summary of the Invention

[0005] This disclosure provides a rearview mirror fixture that can solve the technical problems existing in the related art. The technical solution of the rearview mirror fixture is as follows.

[0006] This disclosure provides a rearview mirror inspection fixture for inspecting rearview mirrors. The rearview mirror inspection fixture includes a base, a first column, a second column, a first simulation body, and a second simulation body.

[0007] The first simulation body is fixed to the base by the first column, and the first simulation body has a through hole;

[0008] The second simulation body includes a first sub-simulation body and a second sub-simulation body. The first sub-simulation body is fixed to the base by the second column, and the second sub-simulation body is detachably connected to the first sub-simulation body.

[0009] The first sub-simulation has a main positioning hole and a first positioning half-hole, and the second sub-simulation has a second positioning half-hole. When the first sub-simulation and the second sub-simulation are connected, the first positioning half-hole and the second positioning half-hole constitute a secondary positioning hole. The main positioning hole and the secondary positioning hole are opposite to the through hole. The main positioning hole is used to connect the main positioning pin of the rearview mirror, and the secondary positioning hole is used to connect the secondary positioning pin of the rearview mirror.

[0010] In one possible implementation, the rearview mirror fixture further includes a third column;

[0011] The third column is fixed to the base, and the third column is hinged to the second sub-simulation body via a pivot.

[0012] In one possible implementation, the rearview mirror fixture further includes a fixing element;

[0013] The second sub-simulation body is fixedly connected to the third column by the fastener.

[0014] In one possible implementation, the fastener is a locking bolt;

[0015] The locking bolt is used to lock the second sub-simulation body and the third column, wherein the axis of the locking bolt is perpendicular to the axis of the rotating shaft.

[0016] In one possible implementation, the second sub-simulation body includes a lower rod body, an upper rod body, and a simulation body body;

[0017] The lower rod is connected to the third column, the upper rod is connected to the lower rod, and the simulated body is connected to the upper rod.

[0018] In one possible implementation, the upper rod is located on the side of the lower rod closer to the first sub-simulation.

[0019] In one possible implementation, the secondary positioning hole is an oblong hole, wherein the major axis of the secondary positioning hole passes through the center of the main positioning hole.

[0020] In one possible implementation, the rearview mirror is mounted in front of the rearview mirror fixture, and the first sub-simulation body and the second sub-simulation body are connected.

[0021] In one possible implementation, the number of the first columns is two.

[0022] In one possible implementation, the rearview mirror fixture further includes a handling handle fixed to the base.

[0023] The technical solution provided in this disclosure includes at least the following beneficial effects:

[0024] This disclosure provides a rearview mirror fixture, which is assembled with a rearview mirror and used to inspect the quality of the rearview mirror. When the rearview mirror is installed on the fixture, the main locating pin of the rearview mirror extends into the main locating hole of the fixture, and the secondary locating pin of the rearview mirror extends into the secondary locating hole of the fixture. After inspection, the rearview mirror is removed from the fixture. When removing the rearview mirror, the first and second sub-simulations of the fixture are first separated, thereby separating the secondary locating hole into a first and a second locating half-hole. Then, the rearview mirror is removed from the fixture. This prevents the undercut structure on the secondary locating pin of the rearview mirror from being blocked by the secondary locating hole, thus avoiding damage to the structure of the secondary locating pin. It also improves the ease of operation for removing the rearview mirror.

[0048] As a crucial decorative component of a car's exterior, the quality of automotive rearview mirrors is primarily assessed through the development of rearview mirror inspection fixtures. To be considered a qualified and usable fixture, its development must meet several key functionalities: first, the fixture's own precision must meet standards; second, the fixture must be easy for personnel to operate; third, the inspection content for the parts must be complete and comprehensive; and fourth, the parts should be easy to assemble and disassemble on the fixture, with stable positioning, among other things.

[0049] In related technologies, the installation and positioning method of automotive exterior rearview mirrors on rearview mirror fixtures is usually the same as the installation and positioning method on the complete vehicle. When assembling automotive exterior rearview mirrors on a complete vehicle, it is often completed by a single employee. To facilitate the employee's operation, a reverse-hook structure is made on the secondary locating pin of the exterior rearview mirror. This reverse-hook structure mainly serves as a pre-attachment mechanism to facilitate employee operation. Existing rearview mirror fixture solutions completely simulate the assembly method of rearview mirrors on the complete vehicle; that is, after the rearview mirror is installed on the fixture, the reverse-hook structure of the secondary locating pin is pre-attached to the secondary locating hole of the rearview mirror fixture. However, the rearview mirror fixtures in related technologies can hinder the removal of the rearview mirror after inspection. If the rearview mirror is forcibly removed, the secondary locating hole may damage the reverse hook structure of the secondary locating pin, thus affecting the ease of operation of the exterior rearview mirror on the rearview mirror fixture.

[0050] In view of the above-mentioned technical problems, embodiments of this disclosure provide a rearview mirror inspection tool, such as... Figure 1 and Figure 2As shown, the rearview mirror inspection fixture is used to inspect the rearview mirror 100. The fixture includes a base 1, a first pillar 2, a second pillar 3, a first simulation body 4, and a second simulation body 5. The first simulation body 4 is fixed to the base 1 via the first pillar 2, and has a through hole 41. Figure 3 and Figure 4 As shown, the second simulation body 5 includes a first sub-simulation body 51 and a second sub-simulation body 52. ​​The first sub-simulation body 51 is fixed to the base 1 by a second column 3, and the second sub-simulation body 52 is detachably connected to the first sub-simulation body 51. The first sub-simulation body 51 has a main positioning hole 511 and a first positioning half-hole 512, and the second sub-simulation body 52 has a second positioning half-hole 521. When the first sub-simulation body 51 and the second sub-simulation body 52 are connected, the first positioning half-hole 512 and the second positioning half-hole 521 constitute a secondary positioning hole 53. The main positioning hole 511 and the secondary positioning hole 53 are opposite to the through hole 41. The main positioning hole 511 is used to connect the main positioning pin 101 of the rearview mirror 100, and the secondary positioning hole 53 is used to connect the secondary positioning pin 102 of the rearview mirror 100.

[0051] The base 1, also known as the base plate, is manufactured within the vehicle's overall reference coordinate system. The base 1 has three reference holes 11, each with a corresponding coordinate system, thus enabling the precision calibration of the inspection fixture.

[0052] The mounting surfaces of the first pillar 2 and the first simulation body 4 are inclined, causing the first simulation body 4 to be arranged at an angle. The first simulation body 4 and the first pillar 2 can be connected by bolts or the like. The first simulation body 4 and the rearview mirror 100 have the same tilt angle on the vehicle. The mounting surfaces of the second pillar 3 and the second simulation body 5 are also inclined, causing the second simulation body 5 to be arranged at an angle. The second simulation body 5 and the second pillar 3 can be connected by bolts or the like.

[0053] like Figures 6-8 As shown, the rearview mirror 100 has a main positioning pin 101 and a secondary positioning pin 102. The secondary positioning pin 102 has an undercut structure 1021. The main positioning pin 101 is connected to the main positioning hole 511 through the through hole 41, and the secondary positioning pin 102 is connected to the secondary positioning hole 53 through the through hole 41. Before removing the rearview mirror 100 from the rearview mirror fixture, the first sub-simulation body 51 and the second sub-simulation body 52 are separated.

[0054] like Figure 2 and Figure 3As shown, the first sub-simulation 51 also has three bolt holes 513. According to the 3-2-1 positioning principle for components, the first reference for installing the rearview mirror 100 is the plane formed by the three bolt holes 513, restricting three degrees of freedom of the rearview mirror 100. The second reference is the main positioning pin 101 and the main positioning hole 511 of the rearview mirror 100, restricting two degrees of freedom of the rearview mirror 100. The third reference is the secondary positioning pin 102 and the secondary positioning hole 53, restricting one degree of freedom of the rearview mirror 100. Furthermore, the main positioning hole 511 and the secondary positioning hole 53 on the first sub-simulation 51 need to be drilled according to the positional requirements of the rearview mirror 100's design drawings.

[0055] like Figure 6 and Figure 7 As shown, the rearview mirror 100 has a boss 104 on its detection surface 103. The main locating pin 101 and the secondary locating pin 102 are both located on the boss 104. The diameter of the through hole 41 of the first simulation body 4 is larger than the outer diameter of the boss 104. The first simulation body 4 simulates the sheet metal outer surface of a door on a vehicle, and the second simulation body 5 simulates the mounting surface of the rearview mirror 100 on the vehicle. After the main locating pin 101, the secondary locating pin 102, and the second simulation body 5 are assembled, parameters such as the gap between the detection surface 103 of the rearview mirror 100 and the first simulation body 4 are detected. The undercut structure 1021 of the rearview mirror 100 is located on the side wall of the secondary locating pin 102, and the undercut structure 1021 is elastically connected to the secondary locating pin 102. When the undercut structure 1021 is subjected to pressure, it can retract into the interior of the secondary locating pin 102. When the undercut structure 1021 is not subjected to external force, the undercut structure 1021 extends out from the inside of the secondary positioning pin 102.

[0056] The technical solution provided in this disclosure involves installing the rearview mirror 100 onto a rearview mirror fixture. The main positioning pin 101 of the rearview mirror 100 extends into the main positioning hole 511 of the fixture, and the secondary positioning pin 102 of the rearview mirror 100 extends into the secondary positioning hole 53 of the fixture. After inspection, the rearview mirror 100 is removed from the fixture. When removing the rearview mirror 100, the first sub-simulation body 51 and the second sub-simulation body 52 of the fixture are first separated, thereby dividing the secondary positioning hole 53 into a first positioning half-hole 512 and a second positioning half-hole 521. Then, the rearview mirror 100 is removed from the fixture. This ensures that the undercut structure 1021 on the secondary positioning pin 102 of the rearview mirror 100 is not blocked by the secondary positioning hole 53, thus avoiding damage to the structure of the secondary positioning pin 102. Simultaneously, it improves the ease of operation for disassembling the rearview mirror 100.

[0057] The following is an exemplary description of how the second sub-simulation 52 and the first sub-simulation 51 are detachably connected.

[0058] In some examples, such as Figure 1 and Figure 3 As shown, the rearview mirror fixture also includes a third column 6. The third column 6 is fixed to the base 1, and the third column 6 is hinged to the second sub-simulation body 52 via a pivot 61.

[0059] When it is necessary to connect the first sub-simulation 51 and the second sub-simulation 52, the first sub-simulation 51 is rotated to the corresponding position so that the first positioning half-hole 512 and the second positioning half-hole 521 can be assembled into a complete secondary positioning hole 53. When it is necessary to separate the first sub-simulation 51 and the second sub-simulation 52, the first sub-simulation 51 is rotated to the corresponding position so that the first positioning half-hole 512 and the second positioning half-hole 521 are separated.

[0060] The pivot 61 serves two purposes. First, it enables precise positioning when the first sub-simulation 51 and the second sub-simulation 52 are connected. The first positioning half-hole 512 and the second positioning half-hole 521 can be aligned and joined together to form the secondary positioning hole 53, preventing the secondary positioning pin 102 from being unable to extend into the secondary positioning hole 53 due to misalignment between the first positioning half-hole 512 and the second positioning half-hole 521. Second, when the first sub-simulation 51 and the second sub-simulation 52 are separated, the second sub-simulation 52 can still be connected to the third column 6 without needing to place the second sub-simulation 52 in another position.

[0061] In some examples, such as Figure 3 and Figure 5 As shown, the rearview mirror fixture also includes a fixing element 7, and the second sub-simulation body 52 and the third column 6 are fixedly connected by the fixing element 7.

[0062] When it is necessary to connect the first sub-simulation 51 and the second sub-simulation 52, the second sub-simulation 52 is rotated along the direction close to the third column 6 via the pivot 61, and then the second sub-simulation 52 and the third column 6 are connected together via the fastener 7.

[0063] When removing the rearview mirror 100 from the rearview mirror fixture, first separate the second sub-simulation body 52 and the third pillar 6 using the fixing member 7, and then rotate the second sub-simulation body 52 away from the third pillar 6 via the pivot 61. In this way, the secondary positioning hole 53 becomes the separated first positioning half-hole 512 and second positioning half-hole 521, thereby allowing the secondary positioning pin 102 of the rearview mirror 100 to easily detach from the secondary positioning hole 53.

[0064] In some examples, such as Figure 3 and Figure 5 As shown, the fixing component 7 is a locking bolt. The locking bolt is used to lock the second sub-simulation 52 and the third column 6, wherein the axis of the locking bolt is perpendicular to the axis of the rotating shaft 61.

[0065] The third column 6 has a groove 601, and the opening of the groove 601 faces away from the first simulation body 4. The bottom wall of the groove 601 has a threaded hole. The second sub-simulation body 52 is located in the groove 601. The locking bolt can connect the second sub-simulation body 52 to the bottom wall of the groove 601, thereby realizing the fixed connection between the second sub-simulation body 52 and the third column 6.

[0066] When removing the rearview mirror 100, first loosen the locking bolt so that it unscrews from the threaded hole in the groove 601, allowing the second sub-simulation 52 to rotate and disengage from the groove 601, thereby separating the second sub-simulation 52 from the third pillar 6. When inspecting the rearview mirror 100 again, tighten the locking bolt to reconnect the second sub-simulation 52 to the bottom wall of the groove 601.

[0067] In other examples, the fastener 7 may also be a locating pin, and the axis of the locating pin may be parallel to the axis of the rotating shaft 61. Pin holes are provided on the sidewalls of the groove 601 and the sidewalls of the second sub-simulation 52. When removing the rearview mirror 100, the locating pin is first pulled out of the pin hole, allowing the second sub-simulation 52 to rotate and disengage from the groove 601, thereby separating the second sub-simulation 52 from the third pillar 6.

[0068] The implementation of the second sub-simulation 52 will be described below as an example.

[0069] In some examples, such as Figure 3 and Figure 5 As shown, the second sub-simulation 52 includes a lower rod 522, an upper rod 523, and a simulation body 524. The lower rod 522 is connected to the third column 6, the upper rod 523 is connected to the lower rod 522, and the simulation body 524 is connected to the upper rod 523.

[0070] The lower rod 522 is located in the groove 601 of the third column 6, and the lower rod 522 and the upper rod 523 can be fixedly connected by bolts. The simulation body 524 and the upper rod 523 are arranged in a bent manner, and the simulation body 524 and the upper rod 523 can be an integral structure.

[0071] If one of the upper rod 523 or the lower rod 522 is damaged, only the damaged rod can be replaced instead of the entire second sub-simulation body 52, thus reducing the wear and tear on parts.

[0072] In some examples, such as Figure 3 and Figure 5 As shown, the upper rod 523 is located on the side of the lower rod 522 closer to the first sub-simulation 51. This shortens the distance between the upper rod 523 and the first sub-simulation 51, thereby shortening the length of the simulation body 524 and reducing the amount of material used in the second sub-simulation 52.

[0073] In some examples, such as Figure 4 As shown, the secondary positioning hole 53 is an oblong hole, wherein the major axis of the secondary positioning hole 53 passes through the center of the main positioning hole 511. Since a circular hole can restrict two degrees of freedom, if both the main positioning hole 511 and the secondary positioning hole 53 are circular holes, it will cause over-positioning of the rearview mirror 100. By setting the secondary positioning hole 53 as an oblong hole, the secondary positioning hole 53 can only restrict one degree of freedom, that is, restrict the rearview mirror 100 from rotating around the main positioning pin 101.

[0074] In some examples, the rearview mirror 100 is mounted in front of the rearview mirror fixture, and the first sub-simulation 51 and the second sub-simulation 52 are connected so that the first positioning half-hole 512 and the second positioning half-hole 521 are aligned to form the secondary positioning hole 53.

[0075] When installing the rearview mirror 100, tighten the locking bolt, and then insert the secondary positioning pin 102 into the secondary positioning hole 53. The undercut structure 1021 on the secondary positioning pin 102 retracts into the secondary positioning pin 102 under the pressure of the side wall of the secondary positioning hole 53. After the undercut structure 1021 passes through the secondary positioning hole 53, it protrudes from the inside of the secondary positioning pin 102. This allows the rearview mirror 100 to be pre-installed on the rearview mirror fixture, facilitating the next step of the operation.

[0076] Of course, in other examples, the secondary positioning pin 102 can be inserted into the first positioning half-hole 512 first, and then the locking bolt can be tightened to connect the second sub-simulation body 52 with the third column 6, thereby aligning the first positioning half-hole 512 and the second positioning half-hole 521 to form the secondary positioning hole 53. This disclosure does not specifically limit this aspect.

[0077] In some examples, such as Figure 1 and Figure 2 As shown, there are two first pillars 2. This allows the force on the first simulation body 4 to be more even, thus making the first simulation body 4 more stable and improving the accuracy of the test results.

[0078] In some examples, such as Figure 1 As shown, the rearview mirror fixture also includes a handling handle 8, which is fixed to the base 1. There are two handling handles 8, which are located on two opposite edges of the base 1, thus facilitating the inspection of the rearview mirror fixture.

[0079] The following is an exemplary description of the process of inspecting rearview mirror 100 using a rearview mirror inspection tool.

[0080] The first step is to tighten the locking bolts so that the lower rod 522 of the second sub-simulation body 52 rotates in the direction close to the third column 6 until the lower rod 522 connects with the bottom of the groove 601 of the third column 6, thereby aligning the first positioning half hole 512 and the second positioning half hole 521 to form the secondary positioning hole 53.

[0081] The second step is to insert the main positioning pin 101 of the rearview mirror 100 into the main positioning hole 511, insert the secondary positioning pin 102 into the secondary positioning hole 53, and make the undercut structure 1021 on the secondary positioning pin 102 pass over the secondary positioning hole 53.

[0082] The third step is to connect the rearview mirror 100 to the bolt hole 513 on the first sub-simulation body 51 using bolts.

[0083] The fourth step is to inspect the rearview mirror 100.

[0084] Fifth step: Loosen the locking bolts, causing the lower rod 522 of the second sub-simulation 52 to rotate away from the third column 6 until the second sub-simulation 52 disengages from the groove 601 of the third column 6. At the same time, loosen the bolts between the rearview mirror 100 and the bolt hole 513.

[0085] Step 6: Remove the rearview mirror 100 from the rearview mirror fixture, and then perform daily 5S (Seiri, Seiton, Seiso, Seiketsu, Shitsuke) organization in the fixture area. Use the handling handle 8 to return the rearview mirror fixture and other inspection components to their initial positions.

[0086] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
