The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0085] Some embodiments of the present application are described in detail. The following embodiments and features of the embodiments can be combined with each other in the case of no conflict.

[0086] Referring to Figures 1 to 3 The present embodiment provides a gauge 100 for detecting a target piece 200, and the target piece 200 is provided with a via hole K1 (see FIG. 1). Figure 2 and Figure 3). The target piece 200 can be a part of a vehicle, for example, an injection molded part with a through hole K1. The gauge 100 comprises a mounting assembly 10, a buckle piece 20, a first reset piece 30 and a pushing assembly 40. The buckle piece 20 is movably connected to the mounting assembly 10, and is provided with a buckle structure 21. The buckle piece 20 has a movable state and an engaged state, so that the buckle piece 20 can be switched from the movable state to the engaged state by passing through the through hole K1 of the target piece 200 and engaging with the target piece 200. Referring to Figure 2 When the buckle piece 20 is in the movable state, the buckle piece 20 can move along the through hole K1 relative to the target piece 200. Referring to Figure 3 When the buckle piece 20 is in the engaged state, the buckle structure 21 engages with the target piece 200. The buckle piece 20 can simulate a buckle part on a part of a vehicle. The first reset piece 30 connects the buckle piece 20 and the mounting assembly 10, and is used to reset the buckle piece 20 to an initial state, wherein the initial state is one of the movable state and the engaged state. Optionally, the first reset piece 30 can be configured as an elastic structure or a mechanical linkage structure and the like. The pushing assembly 40 is movably arranged relative to the mounting assembly 10, and the pushing assembly 40 pushes the buckle piece 20 to switch between the movable state and the engaged state relative to the mounting assembly 10.

[0087] According to the gauge 100 of the embodiment, when the gauge 100 is not working, the gauge 100 is arranged to be spaced apart from the target piece 200. In the case that the initial state of the buckle piece 20 is the movable state, the gauge 100 is moved relative to the target piece 200, so that the buckle structure 21 of the buckle piece 20 passes through the through hole K1 from one side of the target piece 200 to the other side of the target piece 200. Thereafter, the pushing assembly 40 is moved and the buckle piece 20 is moved to the engaged state, so that the buckle structure 21 engages with the target piece 200. In this way, only the pushing assembly 40 needs to keep exerting force on the buckle piece 20 to keep the buckle piece 20 in the engaged state, and thereafter, relevant detection steps can be performed, which can improve the detection effect. After the detection is completed, the pushing assembly 40 is removed, and the first reset piece 30 can drive the buckle piece 20 to move to the movable state, so that the buckle piece 20 can smoothly pass through the through hole K1 and be separated from the target piece 200, thereby ensuring the integrity of the target piece 200.

[0088] In the initial state of the buckle 20 is the engaged state, first by the push assembly 40 driven buckle 20 movement to the active state, and then relative to the target 200 synchronous movement of the installation assembly 10 and push assembly 40, the buckle structure 21 from the target 200 a side through the hole K1 to the other side of the target 200. After moving the push assembly 40, the buckle 20 in the first reset member 30 under the action of the movement to the engaged state, and keep the target 200. Thus, also can simulate parts in the real car under the state of the vehicle, to improve the detection effect. After the end of the detection, moving the push assembly 40 to make the buckle 20 movement to the active state, that is, the buckle 20 through the hole K1 of the target 200 and take out, to ensure the integrity of the target 200.

[0089] Therefore, according to the present embodiment of the gauge 100, can simulate the actual installation state of the vehicle buckle parts hook pull positioning state, and can ensure the integrity of the target 200 after the completion of the detection.

[0090] In some embodiments, the buckle structure 21 and the target 200 engaged is that the buckle structure 21 against the side of the target 200, and with the target 200 stable fit, thereby improving the simulation accuracy of parts in the real car under the state.

[0091] The following example is described with the initial state of the buckle 20 is the active state, the push assembly 40 for driving the buckle 20 movement to the engaged state. The buckle 20 in the first reset member 30 under the action of the keep in the engaged state, the push assembly 40 for driving the buckle 20 movement to the active state of the implementation is not described, the two kinds of implementation of the structure is roughly the same.

[0092] Referring to Figure 2 , the push assembly 40 and the buckle 20 relative spacing is provided, in the push assembly 40 and the buckle 20 spacing is provided, the buckle 20 is in the active state. The push assembly 40 can be relative to the installation assembly 10 movement to the buckle 20, and drive the buckle 20 relative to the installation assembly 10 movement, to overcome the elastic force of the first reset member 30, and make the buckle 20 movement to the engaged state, and engaged in the target 200.

[0093] In this way, the gauge 100 in the push assembly 40 and the buckle 20 spacing state, the buckle 20 is kept in the active state, in order to facilitate the operator directly move the gauge 100, and make the buckle 20 through the hole K1, thereby improving the use of the convenience of the gauge 100.

[0094] In some embodiments, referring to Figure 2 and Figure 3The number of the buckle members 20 is two, and the two buckle members 20 are provided with a plug-in gap Q2. The distance between the two buckle structures 21 is the maximum distance between the two surfaces of the two buckle structures 21 arranged opposite to each other. When the two buckle members 20 are in the active state, the distance between the two buckle structures 21 is less than the inner diameter of the through hole K1. The pushing assembly 40 can move into the plug-in gap Q2 and abut against the two buckle members 20 to move the two buckle structures 21 of the two buckle members 20 opposite to each other until the two buckle members 20 enter the buckling state. In this way, by providing the two buckle members 20, the buckle parts on the known parts can be more accurately simulated, and the simulation reliability is improved. At the same time, by arranging the pushing assembly 40 and the plug-in gap Q2 corresponding to each other along the first direction X, the pushing assembly 40 can conveniently push multiple buckle members 20 to move at the same time, and the position of the multiple buckle members 20 can be switched synchronously.

[0095] In some embodiments, when the two buckle members 20 are in the buckling state, the distance between the buckle structures 21 of the two buckle members 20 is greater than the inner diameter of the through hole K1, so that the buckling reliability between the buckle member 20 and the target part 200 can be better guaranteed.

[0096] In other embodiments, the number of the buckle members 20 can also be configured to be multiple, and the multiple buckle members 20 are distributed around the circumferential direction of the guide hole K2. The multiple buckle members 20 enclose the plug-in gap Q2.

[0097] When the number of the buckle members 20 is single, when the buckle member 20 is in the active state, the projection of the buckle member 20 along the first direction X in the radial direction of the through hole K1 is smaller than the inner diameter of the through hole K1, and when the buckle member 20 is in the buckling state, the projection of the buckle member 20 along the first direction X is located outside the through hole K1. In this way, the buckle member 20 can be buckled to the target part 200.

[0098] In some embodiments, referring to Figure 2 and Figure 3 The buckle member 20 comprises a main body part 22, and the main body part 22 is rotatably connected with the mounting assembly 10. The buckle structure 21 is a boss protruding from the side surface of the main body part 22, and the buckle structure 21 and the main body part 22 jointly form an L-shaped hook structure. The cross-sectional area of the boss gradually decreases in the direction away from the main body part 22, and in the embodiment, the boss is configured as a triangular boss. The buckle structures 21 of the two buckle members 20 are arranged on the surfaces of the two main body parts 22 arranged opposite to each other, respectively.

[0099] In some embodiments, referring to Figure 2 and Figure 3The body part 22 has a pushing surface P3 at one end of the body part 22 facing the guiding hole K2 in the first direction X away from the buckle structure 21. The pushing surfaces P3 of the two body parts 22 form the aforementioned insertion gap Q2. The pushing assembly 40 further comprises a pushing pin 43. The pushing pin 43 is used to abut against the pushing surfaces P3 to drive the buckle 20 to rotate relative to the mounting assembly 10 and to move the two buckle structures 21 away from each other to the engaged state. When the pushing pin 43 is moved away from the buckle 20, the first reset member 30 drives the two buckles 20 to return to the active state.

[0100] When the buckle 20 is in the active state, the two pushing surfaces P3 are obliquely intersected and in surface contact with the pushing pin 43. When the buckle 20 is in the engaged state, the two pushing surfaces P3 are substantially parallel. During the movement of the pushing pin 43 pushing the pushing surfaces P3, the buckle 20 rotates relative to the mounting assembly 10, and the pushing surfaces P3 rotate relative to the pushing pin 43, until the two pushing surfaces P3 substantially adhere to the surfaces of the pushing pin 43 arranged away from each other and substantially parallel to each other, so that the pushing surfaces P3 are in surface contact with the pushing pin 43, at this time the buckle 20 is in the engaged state, which can improve the stability of the buckle 20 in the engaged state. In other embodiments, the pushing surfaces P3 can also be in line contact with the pushing pin 43 when the buckle 20 is in the engaged state.

[0101] In some embodiments, referring to Figure 4 and Figure 5 , the buckle 20 comprises a body part 22. One end of the body part 22 is rotatably connected to the mounting assembly 10, the first reset member 30 is elastically supported between the body part 22 and the mounting assembly 10, and the other end of the body part 22 is connected to the buckle structure 21. By rotatably connecting the body part 22 to the mounting assembly 10, the freedom degree between the body part 22 and the mounting assembly 10 is small, which can improve the movement stability of the body part 22 relative to the mounting assembly 10, and further improve the switching reliability of the buckle 20 between the active state and the engaged state.

[0102] In some embodiments, referring to Figure 4 and Figure 5 , the buckle 20 further comprises a pivot 23. The pivot 23 is connected to the body part 22, and the two ends of the pivot 23 are rotatably connected to the mounting assembly 10, respectively. The first reset member 30 is sleeved on the pivot 23, one end of the first reset member 30 elastically abuts against the body part 22, and the other end of the first reset member 30 elastically abuts against the mounting assembly 10. In this way, while realizing the rotatable connection between the body part 22 and the mounting assembly 10, the convenient installation of the first reset member 30 can also be considered. The first reset member 30 can be specifically configured as a torsion spring 30a. One end of the torsion spring 30a abuts against the body part 22, and the other end of the torsion spring 30a abuts against the mounting assembly 10.

[0103] In some embodiments, referring toFigure 4 and Figure 5 The buckle structure 21 is provided with a first abutting surface P1 extending to the surface of the body portion 22 in a cross section perpendicular to the third direction Z. The target member 200 is provided with a second abutting surface P2, and the first abutting surface P1 abuts against the second abutting surface P2 after the buckle member 20 enters the engaged state, so as to simulate the actual hooking state of the buckle structure 21.

[0104] In other embodiments, the body portion 22 and the mounting assembly 10 can also be movably connected through a universal joint structure, a connecting rod structure or other transmission structures.

[0105] In some embodiments, referring to Figure 4 and Figure 5 The body portion 22 is further provided with two matching portions 24 at the end away from the buckle structure 21, the two matching portions 24 are movably connected to the pivot 23 along the third direction Z, and the first reset member 30 is sleeved on the portion of the pivot 23 between the two matching portions 24. In this way, the two matching portions 24 can limit the axial movement of the torsion spring 30a, preventing the torsion spring 30a from falling out, and improving the force stability of the first reset member 30.

[0106] In other embodiments, the number of matching portions 24 can be one or more than three.

[0107] In some embodiments, referring to Figure 4 and Figure 5 The mounting assembly 10 defines a mounting cavity Q1 having a first opening K41 and a second opening K42 arranged opposite to each other along the first direction X. One end of the buckle member 20 is located in the mounting cavity Q1 and movably connected to the mounting assembly 10, and the other end of the buckle member 20 extends out of the mounting cavity Q1 from the first opening K41 and is connected to the buckle structure 21. The pushing assembly 40 movably passes through the second opening K42.

[0108] In this way, the cooperation between the pushing assembly 40 and the buckle member 20 is completed in the mounting cavity Q1, which can improve the protection of the transmission cooperation between the pushing assembly 40 and the buckle member 20, and ensure the reliability of the movement of the pushing assembly 40 driving the buckle member 20.

[0109] In some embodiments, referring to Figure 4 and Figure 5The mounting assembly 10 comprises a first mounting member 12 and a second mounting member 13. The first mounting member 12 is provided with a first receiving hole K5, one end of which is formed as a first opening K41. The second mounting member 13 is arranged on the side of the first mounting member 12 away from the buckle structure 21. The second mounting member 13 is provided with a mounting groove C1 on the side thereof facing the first mounting member 12. The second mounting member 13 is provided with a second receiving hole K6 on the side thereof away from the first mounting member 12. The second receiving hole K6 is in communication with the mounting groove C1. One end of the second receiving hole K6 away from the mounting groove C1 is formed as a second opening K42. The first receiving hole K5, the mounting groove C1 and the second receiving hole K6 jointly form a mounting cavity Q1. In this way, the separate design of the first mounting member 12 and the second mounting member 13 can reduce the assembly difficulty of the buckle member 20. Moreover, the mounting groove C1 can provide a movement space for the buckle member 20 to move. The first receiving hole K5 can facilitate the buckle member 20 to extend out of the mounting assembly 10. The second receiving hole K6 can facilitate the pushing assembly 40 to extend into the mounting groove C1 to drive the buckle member 20 to move.

[0110] In the working process of the gauge 100, the first mounting member 12 is attached to the surface of the target piece 200. The first mounting member 12 can also be positioned and matched with the target piece 200 to position the buckle member 20 in the via hole K1. Specifically, the first mounting member 12 can be configured as a positioning insert.

[0111] In other embodiments, the mounting assembly 10 can also be configured as a first part and a second part distributed along the axial direction of the pivot 23. The first part and the second part are symmetrical to each other and form a complete receiving cavity after being buckled, which can also achieve the effect of facilitating the installation of the buckle member 20. Therefore, the specific structure of the mounting assembly 10 can be determined according to actual needs.

[0112] In some embodiments, the two matching portions 24 of the buckle member 20 respectively abut against the groove side surfaces of the mounting groove C1, and the pivot 23 of the buckle member 20 is rotatably extended into the second mounting member 13. In this way, through the cooperation of the mounting groove C1 and the matching portion 24, the second mounting member 13 can limit the buckle member 20.

[0113] In some embodiments, the pushing assembly 40 comprises a first limiting portion 51, and the mounting assembly 10 comprises a second limiting portion 52 configured to limit the pushing assembly 40 in the limiting position by limiting cooperation with the first limiting portion 51. When the pushing assembly 40 is in the limiting position, the pushing assembly 40 pushes the buckle member 20 to keep it in the active state or the buckled state.

[0114] Therefore, the buckle 20 can be limited to one of the engaged state or the active state by the first reset member 30, and can be limited to the other one of the engaged state or the active state by the pushing assembly 40 in the limiting position. Therefore, whether in the process of installing the gauge 100 on the target piece 200 or in the process of keeping the buckle 20 engaged with the target piece 200, it is not necessary to manually control the pushing assembly 40 to keep applying the force to the buckle 20, thereby improving the operation convenience of the gauge 100.

[0115] In the embodiment, referring to Figure 6 and Figure 7 , the pushing assembly 40 is in the limiting position, and the buckle 20 is in the engaged state.

[0116] In some embodiments, referring to Figure 8 , one of the first limiting part 51 and the second limiting part 52 is a limiting slot 51a, and the other one of the first limiting part 51 or the second limiting part 52 is a limiting column 52a. The limiting column 52a is movably fitted in the limiting slot 51a. The limiting slot 51a includes a first slot section 511 and a second slot section 512. The first slot section 511 is arranged to extend along the first direction X, and the second slot section 512 is connected to one end of the first slot section 511 and arranged to extend along the second direction Y intersecting the first direction X. The length direction of the pushing assembly 40 is parallel to the first direction X. After the pushing assembly 40 moves relative to the mounting assembly 10 to the limiting column 52a moving to the second slot section 512, the second slot section 512 can limit the limiting column 52a in the first direction X, so that the pushing assembly 40 is kept in the limiting position.

[0117] Therefore, the relative displacement of the pushing assembly 40 and the mounting assembly 10 in the second direction Y can realize the limiting of the two in the first direction X, and meanwhile, the first slot section 511 can ensure that there is a displacement amount of the pushing assembly 40 and the mounting assembly 10 in the first direction X, so as to ensure that the displacement of the pushing assembly 40 in the first direction X can drive the buckle 20 to switch between the engaged state and the active state.

[0118] In some embodiments, referring to Figure 7 , the mounting assembly 10 is provided with a guide hole K2 extending along the first direction X. The guide hole K2 is arranged in the guide sleeve 11. The length direction of the guide sleeve 11 is parallel to the first direction X. The guide sleeve 11 is arranged to pass through the second receiving hole K6 and connected with the second mounting piece 13. The limiting slot 51a is arranged in the wall of the guide sleeve 11 and communicated with the guide hole K2. The pushing assembly 40 includes a pushing piece 41. The pushing piece 41 is movably fitted in the guide hole K2 along the first direction X. Therefore, the guide hole K2 can improve the accuracy of the movement direction of the pushing piece 41.

[0119] In some embodiments, the first limiting part 51 is a limiting groove 51a, and the second limiting part 52 is a limiting column 52a. The limiting column 52a is protruded on the outer circumferential surface of the pushing piece 41 and is arranged in the limiting groove 51a. The second direction Y is the circumferential direction of the guide hole K2. In this way, by pushing the pushing piece 41 to the corresponding position of the second direction Y and the second groove segment 512, the limiting column 52a can be slid into the second groove segment 512 by rotating the pushing piece 41, which has the advantage of simple and convenient operation.

[0120] In other embodiments, the guide hole K2 and the limiting groove 51a can be arranged on the pushing piece 41, and the limiting column 52a is arranged on the outer circumferential surface of the guide sleeve 11.

[0121] In other embodiments, the mounting assembly 10 and the pushing assembly 40 can also be configured as a sliding rail matching structure, and the first limiting part 51 and the second limiting part 52 can be configured as snap-fitting components.

[0122] In some embodiments, referring to Figure 7 and Figure 8 , the gauge 100 further comprises a second reset piece 60. The second reset piece 60 connects the mounting assembly 10 and the pushing assembly 40, and is used to reset the pushing assembly 40 from the limiting position to the initial position. When the pushing assembly 40 is in the initial position, the pushing assembly 40 is spaced apart from the buckle piece 20, so that the first reset piece 30 can drive the buckle piece 20 to reset to the initial state. In this way, through the linkage of the second reset piece 60 and the first reset piece 30, the buckle piece 20 can be automatically switched to the initial state after the detection is completed, which is convenient for operation.

[0123] In some embodiments, the second reset piece 60 can be configured as a compression spring, which is sleeved on the pushing piece 41 and elastically abuts between the inner wall of the guide sleeve 11 and the pushing piece 41. In other embodiments, the second reset piece 60 can also be configured as a tension spring or an elastic column, or a transmission structure that can realize the reset function, which is not limited in the present embodiment.

[0124] In some embodiments, referring to Figure 7The pushing assembly 40 comprises a pushing member 41. The pushing member 41 is movably arranged in the guide hole K2 along the first direction X.

The second reset member 60 is sleeved on the pushing member 41, and the two ends of the second reset member 60 are respectively abutted between the first boss 111 and the pushing member 41. The pushing member 41 comprises a first pushing part 411 and a second pushing part 412. The second pushing part 412 is connected to one end of the first pushing part 411 along the first direction X, and the other end of the first pushing part 411 along the first direction X is connected with the pushing pin 43. The projection of the first pushing part 411 along the first direction X is located inside the outer peripheral side surface of the second pushing part 412. The second reset member 60 is sleeved on the first pushing part 411 and abutted between the first boss 111 and the second pushing part 412.

[0125] In some embodiments, referring to Figure 7 , the hole face of the guide hole K2 is further provided with a second boss 112, and the second boss 112 is located at the one end of the first boss 111 away from the buckle member 20 along the first direction X. The projection of the inner side surface of the second boss 112 along the first direction X is located inside the outer peripheral side surface of the second pushing part 412. In this way, during the movement of the pushing member 41 towards the buckle member 20 along the first direction X, the second boss 112 can limit the second pushing part 412, thereby preventing the problem of excessive force applied by the first pushing part 411 to the buckle member 20.

[0126] In some embodiments, referring to Figure 7 and Figure 8 , the pushing assembly 40 further comprises a holding member 42. The holding member 42 is arranged along the first direction X. The one end of the holding member 42 towards the pushing member 41 is provided with a positioning groove C2. The one end of the second pushing part 412 away from the first pushing part 411 can be accommodated in the positioning groove C2, so that the operator can drive the pushing member 41 to move through the holding member 42, thereby improving the operation convenience.

[0127] In some embodiments, the holding member 42 is further provided with a positioning hole K3, and the positioning hole K3 is communicated with the positioning groove C2. The pushing assembly 40 further comprises a positioning part 44. The positioning part 44 is connected to the one end of the second pushing part 412 away from the first pushing part 411. The positioning part 44 extends into the positioning hole K3 to limit the holding member 42 and the pushing member 41 along the circumference of the guide hole K2, thereby facilitating the operator to rotate the pushing member 41 by rotating the holding member 42. Optionally, the positioning hole K3 extends to the opening of the positioning groove C2, so as to facilitate the cooperation between the pushing member 41 and the holding member 42. In other embodiments, the positioning hole K3 can also be spaced apart from the opening of the positioning groove C2.

[0128] In some embodiments, the outer peripheral surface of the holding member 42 can be knurled to further improve the holding feeling.
