[0006] In one embodiment, the detection component further includes a limiter, which is connected to the detection block via a connecting structure, and the limiter is opposite to and spaced from a detection surface of the detection block, and the limiter is used to limit the hinge movable leaf together with the detection surface.

[0007] In one embodiment, the limiting member is connected to the detection block via an elastic movable connection structure, and the elastic movable connection structure is used to provide a restoring force for the limiting member in a direction close to the detection surface to elastically support the movable leaf.

[0008] In one embodiment, a mounting portion is provided on one side of the detection block, and a through hole is provided through the mounting portion in a first direction;

[0009] The through hole is penetrated by a guide column extending along the first direction, one end of the guide column close to the fixing seat is installed with the limiter, and the other end of the installation column is provided with a limit portion;

[0010] The elastic member is arranged on a side of the limiting portion and the mounting portion facing away from the fixing seat.

[0011] In one embodiment, the elastic member includes a spring sleeved on the other end of the mounting post.

[0012] In one embodiment, the detection block is provided with a through hole extending perpendicularly to the detection surface, and the detection device further comprises a detection rod, which is used to penetrate the through hole, and the end of the detection rod is used to penetrate the mounting hole of the hinge movable leaf.

[0013] In one embodiment, the detection device also includes a reference block, which is used to be detachably installed on a side of the detection block where the detection surface is provided. The reference block has a first side surface and a second side surface, the first side surface is used to fit with the detection surface, and the second side surface is used to fit with the hinge movable page, and the plane where the first side surface is located is intersected with the plane where the second side surface is located.

[0017] The technical solution of the present invention uses a fixed seat to limit the fixed page of the hinge, at least in a first direction. The detection component and the fixed seat are arranged relative to each other in the first direction. The detection component includes a base and a scale on the base and extending along the first direction. The detection block is slidably installed on the base along the first direction. A detection surface is set on the side of the detection block facing the fixed seat. The movable page is rotated to slide the detection block so that the movable page is in contact with the detection surface.

The distance of the mark point in the first direction can be set as an edge on the fixed page, or the center position of the positioning hole on the fixed seat. Calculate the theoretical distance between the movable page and the mark point at this angle, add the error range, and get the appropriate position range. Read the scale value corresponding to the identification part and compare it with the reasonable position range. When the scale value is within a reasonable range, it proves that the hinge is qualified and the position of the door after the hinge is positioned and installed is normal. When the scale value is not within a reasonable range, the hinge is unqualified and the position of the door after the hinge is positioned and installed must be abnormal. Remove the abnormal hinge in advance to ensure the assembly quality. BRIEF DESCRIPTION OF THE DRAWINGS

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] The existing inspection fixture cannot quantify the distance in the X direction from the hinge movable page to a marked point on the fixed page at a specific angle. If the distance cannot be measured, it is unknown whether the hinge is qualified and the position of the door after installation cannot be guaranteed.

[0029] The invention provides a detection device.

[0030] See also Figure 1In one embodiment of the present invention, the detection device 100 includes a fixed base 1 and a detection component 2, wherein the fixed base 1 is used for installing a hinge fixed page; the detection component 2 is arranged opposite to the fixed base 1 in a first direction, and the detection component 2 includes a base 21, a detection block 22 movably installed on the base 21 along the first direction, and a measuring structure, wherein a side of the detection block 22 facing the fixed base 1 is a detection surface 221, and the detection surface 221 is used to abut against the outer side surface of the hinge movable page, and the measuring structure includes a scale provided on the base 21 and extending along the first direction, and an identification portion movably installed at the scale along the first direction, and the identification portion is fixedly connected to the detection block 22 so as to be driven by the fixed block to move along the first direction.

[0031] The technical solution of the present invention uses a fixed seat 1 to limit the fixed page of the hinge, at least in the first direction. The detection component 2 is arranged relative to the fixed seat 1 in the first direction. The detection component 2 includes a base 21 and a scale on the base 21 and extending along the first direction. The detection block 22 is slidably installed on the base 21 along the first direction. The detection block 22 is provided with a detection surface 221 on the side facing the fixed seat 1. The movable page is rotated to slide the detection block 22 so that the movable page is in contact with the detection surface 221. At this time, the angle between the movable page and the fixed page is the angle between the movable page and the fixed page when the vehicle door is closed. At this time, the angle between the movable page and the fixed page is observed by the scale. The distance in the first direction between the movable page and a marking point on the fixed page, the marking point can be set to an edge on the fixed page, or the center position of the positioning hole on the fixing seat 1, calculate the theoretical distance between the movable page and the marking point at the angle, add the error range, and get the appropriate position range, by reading the scale value corresponding to the identification part, and compare it with the reasonable position range, when the scale value is within a reasonable range, it proves that the hinge is qualified, and the position of the door after the hinge positioning is installed is normal, when the scale value is not within a reasonable range, the hinge is unqualified, and the position of the door after the hinge positioning is installed must be abnormal, and the abnormal hinges should be removed in advance to ensure the assembly quality.

[0032] Since the movable page cannot be kept in contact with the detection surface 221 after being rotated to a specific angle, and cannot be kept under the action of gravity, in order to keep the movable page and the detection surface 221 in close contact during reading and ensure the accuracy of the reading, the detection component 2 also includes a limiter 23, see Figure 1 and Figure 2The limiter 23 is connected to the detection block 22 through a connection structure, and the limiter 23 is arranged opposite to and spaced from the detection surface 221 of the detection block 22, and the limiter 23 is used to limit the hinge movable leaf together with the detection surface 221. The detection surface 221 abuts against one side of the movable leaf, and the limiter 23 abuts against the other side of the movable leaf, thereby limiting the movable leaf in the first direction, ensuring that the movable leaf can maintain a state of being in contact with the detection surface 221, and ensuring the accuracy of the reading.

[0033] In order to enable the limiting member 23 to exert a force in the first direction on the movable leaf, the limiting member 23 is connected to the detection block 22 via an elastic movable connection structure 24, and the elastic movable connection structure 24 is used to provide a reset force for the limiting member 23 in a direction close to the detection surface 221 to elastically support the movable leaf. Without applying an external force, the limiting member 23 abuts against the other side of the movable leaf. When the movable leaf needs to be adjusted or the hinge needs to be removed, the elastic force of the elastic movable connection structure 24 is overcome to separate the limiting member 23 from the movable leaf.

[0034] In one embodiment, see Figure 2 The specific structure is as follows: a mounting portion 222 is provided on one side of the detection block 22, and a through hole is provided through the mounting portion 222 in the first direction; a guide column 241 extending in the first direction is provided through the through hole, and the limiter 23 is installed at one end of the guide column 241 close to the fixing seat 1, and a limiter 242 is provided at the other end of the mounting column; the elastic member 243 is provided on the side of the limiter 242 and the mounting portion 222 facing away from the fixing seat 1. The elastic member 243 includes but is not limited to a spring, which is sleeved on the guide column 241, and is in a compressed state, with one end abutting against the limiter 242 and the other end abutting against the mounting portion 222. Under the elastic force of the spring, the limiter 23 moves toward the detection surface 221 in the first direction, thereby clamping and fixing the movable page together with the measuring block.

[0035] In addition, the hinge detection also includes the detection of the installation hole position on the hinge movable leaf, and the detection method is: the movable leaf is rotated to another specific angle, and when the detection rod 25 moving along a specific direction can pass through the installation hole on the movable leaf, the installation hole position meets the requirements; if the detection rod 25 cannot pass through the installation hole on the movable leaf, the installation hole position does not meet the requirements. For details, please refer to Figure 2 The detection block 22 is provided with a through hole 223 which penetrates in a direction perpendicular to the detection surface 221. The detection device 100 also includes a detection rod 25, which is used to penetrate the through hole 223. The through hole 223 guides the detection rod 25 to ensure that the moving direction of the detection rod 25 remains unchanged. The end of the detection rod 25 is used to penetrate the mounting hole of the hinge movable leaf.

[0036] When detecting the position of the mounting hole, the movable leaf needs to be rotated to another specific angle. In order to ensure the rotation angle, the detection device 100 also includes a reference block 26. Figure 2 and Figure 3 , the reference block 26 is used to be detachably mounted on the side of the detection block 22 provided with the detection surface 221. The reference block 26 has a first side 261 and a second side 262. The first side 261 is used to fit with the detection surface 221, and the second side 262 is used to fit with the hinge movable leaf. The plane where the first side 261 is located intersects with the plane where the second side 262 is located. Since the detection block 22 is slidable, the sliding block is slid to drive the reference block 26 to move so that the movable leaf fits with the second side 262. When the movable leaf fits with the second side 262, the required hinge opening angle is obtained. At this time, the limit member 23 and the reference block 26 jointly clamp and fix the movable leaf to facilitate the detection rod 25 to perform perforation detection.

[0037] Since the device uses different reference surfaces when measuring the position of the movable page in the first direction and detecting the position of the mounting hole, the reference block 26 can only be detachably mounted on the detection block 22. The detachable manner is various, and it can be magnetically attracted or connected by screws. Specifically, the detection block 22 is provided with two threaded holes on one side of the detection surface 221, and the reference block 26 is correspondingly provided with two through countersunk holes, and the detection block 22 is connected to the reference block 26 by screws. The two threaded holes are provided to prevent the reference block 26 from rotating along the screw, so that the second side 262 cannot always fit with the movable page. The countersunk hole is provided to prevent the screw head from protruding from the second side 262, so that the second side 262 cannot always fit with the movable page.

[0038] The main function of the fixing seat 1 is to limit the fixed page in the first direction, so a limiting column 11 is provided to cooperate with the positioning hole on the fixed page, and the fixing seat 1 includes two limiting columns 11, which are arranged at intervals along the first direction. The purpose is to prevent the fixed page from rotating around the limiting column 11, so that the movable page cannot fit with the detection surface 221.

[0039] In order to completely fix the fixed page on the fixing base 1, the detection device 100 also includes a vertical toggle clamp 3, see Figure 1 The vertical toggle clamp 3 is disposed on one side of the fixing seat 1, and the vertical toggle clamp 3 has a pressing end 31, and the pressing end 31 has at least an active stroke along the second direction, which is used to limit the hinge fixed page in the second direction. At this time, the fixed page is completely fixed, and the rotation path of the movable page is determined, ensuring that it can fit with the detection surface 221 or the second side surface 262 at a certain angle.

[0040] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
