[0082] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0083] In the related art, to facilitate installation and removal of child seats, the seat body and base structure of the child seat are usually designed to be detachable. The base structure is provided with a handle and a locking assembly, which are connected by a pull rod. Pulling the handle can drive the locking assembly from a locked position to an unlocked position via the pull rod, thereby achieving detachment between the seat body and the base structure.

[0084] Before child seats leave the factory, they need to be inspected to ensure that their various components are securely connected. Currently, this inspection is typically done manually, which is slow and prone to human error. This results in a cumbersome, inaccurate, and time-consuming process.

[0085] Based on this, in order to solve the technical problems of the current child seat 20 detection process being cumbersome, low detection accuracy, and time-consuming and labor-intensive, reference is made to Figures 1 to 12 One embodiment of the present invention provides a testing jig 10 for testing a child seat 20. The child seat 20 includes a seat body 201, a handle 202, and a locking assembly 203. The handle 202 and the locking assembly 203 are both connected to the seat body 201. The handle 202 is connected to the locking assembly 203. The handle 202 is configured to drive the locking assembly 203 from a locked position to an unlocked position relative to the seat body 201. The testing jig 10 includes a base 100, a support assembly 200, a positioning assembly 300, a drive assembly 400, and a first sensor assembly 500.

[0086] The base 100 provides an installation foundation for the various components of the detection jig 10. In order to facilitate the loading and unloading of the child seat 20 on the detection jig 10, the base 100 can be connected to the slide rail 110. One end of the slide rail 110 can be provided with a detection position, and the other end of the slide rail 110 can be provided with a discharge position. When the child seat 20 needs to be inspected, the base 100 can be moved along the slide rail 110 to the detection position to realize the inspection of the child seat 20 at the detection position. After the inspection of the child seat 20 is completed, and it is determined through inspection that the structure of the child seat 20 is intact, the base 100 can be moved along the slide rail 110 to the discharge position to realize the discharge of the child seat 20. By providing the slide rail 110, the detection jig 10 can be moved to different working positions to ensure that the loading, inspection and discharge of the child seat 20 do not interfere with each other. The support assembly 200 is connected to the base 100, and the support assembly 200 is suitable for supporting the seat body 201. The positioning assembly 300 is connected to the base 100 and includes a first cylinder 310 and a second cylinder 320. The first cylinder 310 is adapted to press the seat body 201 laterally to limit the lateral displacement of the child seat 20; the second cylinder 320 is adapted to press the seat body 201 vertically from top to bottom to limit the vertical displacement of the child seat 20. The drive assembly 400 is connected to the base 100 and is used to drive the handle 202 to move, thereby driving the locking assembly 203 from a locked position to an unlocked position. The first sensor assembly 500 is connected to the base 100 and is used to sense the movement state of the locking assembly 203.

[0087] Specifically, in this embodiment, when using the inspection jig 10 to inspect the child seat 20, the inspection jig 10 is first moved to the inspection position, and the child seat 20 is loaded onto the inspection jig 10 using a robot or manually. The support assembly 200 can support the seat body 201 of the child seat 20. For example, the support assembly 200 can support the headrest portion of the seat body 201, and the support assembly 200 can also support the base portion of the seat body 201. By applying a lateral squeezing force to the seat body 201 through the first cylinder 310 of the positioning assembly 300, the lateral positioning of the seat body 201 on the detection jig 10 can be achieved. By applying a vertical squeezing force to the seat body 201 through the second cylinder 320 of the positioning assembly 300, the vertical positioning of the seat body 201 on the detection jig 10 can be achieved. As a result, the positioning assembly 300 can limit the freedom of the seat body 201 in both the lateral and vertical directions to clamp the seat body 201 to the detection jig 10, prevent the seat body 201 from shaking during detection, and ensure the detection accuracy of the seat body 201.

[0088] After the child seat 20 is positioned on the inspection jig 10, all structures of the child seat 20 are connected, meaning the locking assembly 203 is in the locked position. The first sensor assembly 500 has a first detection state that senses the locking assembly 203 in the locked position. When the drive assembly 400 drives the handle 202 to move, the handle 202 drives the locking assembly 203 from the locked position to the unlocked position, causing the seat body 201 and the base structure to be disassembled. This means the locking assembly 203 is in the unlocked position, and the first sensor assembly 500 can sense the movement of the locking assembly 203. The first sensor assembly 500 has a second detection state that senses the locking assembly 203 in the unlocked position. The first detection state can be used to determine whether the seat body 201 and the base structure are stably connected, and the second detection state can be used to determine whether the seat body 201 and the base structure can be disassembled normally.

[0089] In this embodiment, the detection fixture 10 can detect whether the various structures of the child seat 20 can be stably connected and normally disassembled, which is beneficial to improving the detection efficiency and detection accuracy of the child seat 20, reducing human errors, and realizing the automation of the detection of the child seat 20, saving time and effort.

[0090] In some embodiments, reference Figure 1 and Figure 11 The detection fixture 10 also includes a second sensor component 600, which is connected to the base 100. The second sensor component 600 includes a first sensing portion 610 and a second sensing portion 620 that are spaced apart from each other. The first sensing portion 610 emits light, and the second sensing portion 620 receives the light emitted by the first sensing portion 610. The area between the first sensing portion 610 and the second sensing portion 620 is suitable for arranging the child seat 20. The detection fixture 10 is configured such that after the child seat 20 is positioned, the child seat 20 blocks the light emitted by the first sensing portion 610.

[0091] Specifically, in this embodiment, when the child seat 20 is not installed on the inspection jig 10, that is, when there is no child seat 20 between the first sensing portion 610 and the second sensing portion 620, the light emitted by the first sensing portion 610 is not blocked, and the second sensing portion 620 can receive the light emitted by the first sensing portion 610. When the child seat 20 is installed on the inspection jig 10, that is, when there is a child seat 20 between the first sensing portion 610 and the second sensing portion 620, the light emitted by the first sensing portion 610 is blocked by the child seat 20, and the second sensing portion 620 cannot receive the light emitted by the first sensing portion 610. The signal received by the second sensing portion 620 can be used to determine whether the child seat 20 is properly installed on the inspection jig 10. Only when the child seat 20 is properly installed on the inspection jig 10 will the inspection jig 10 perform a structural inspection on the child seat 20, thereby ensuring the inspection accuracy of the inspection jig 10.

[0092] In some embodiments, reference Figure 1 and Figure 11 The support assembly 200 includes a first support group 210, a second support group 220, a third support group 230, and a fourth support group 240. The first support group 210 is adapted to support the head side of the child seat 20, the second support group 220 is adapted to support the back side of the child seat 20, the third support group 230 is adapted to support the leg side of the child seat 20, and the fourth support group 240 is adapted to support the handle end covers 204 on both sides of the child seat 20. The first sensor assembly 500 includes a third sensing portion 510, a fourth sensing portion 520, and a fifth sensing portion 530. The third sensing portion 510 is connected to the first support group 210, the fourth sensing portion 520 is connected to the second support group 220, and the fifth sensing portion 530 is connected to the third support group 230.

[0093] Specifically, in this embodiment, the area enclosed by the first support group 210, the second support group 220, the third support group 230, and the fourth support group 240 matches the shape of the child seat 20. Since the back of the child seat 20 is generally curved, the first support group 210 for supporting the head side of the child seat 20, the second support group 220 for supporting the back side of the child seat 20, and the third support group 230 for supporting the leg side of the child seat 20 can be arranged on the same straight line. There is a height difference between the first support group 210, the second support group 220, and the third support group 230, so that the first support group 210, the second support group 220, and the third support group 230 are respectively supported at different positions on the child seat 20, thereby achieving multi-point support and fixation of the child seat 20. The first support group 210, the second support group 220, and the third support group 230 together support the child seat 20 in the length direction, and the fourth support group 240 supports the child seat 20 in the width direction. The first support group 210, the second support group 220, the third support group 230 and the fourth support group 240 can achieve preliminary clamping between the child seat 20 and the detection fixture 10 to ensure the positioning accuracy of the child seat 20 on the detection fixture 10 and ensure the detection accuracy of the child seat 20 by the detection fixture 10.

[0094] To ensure the stability of the connection between the seat body 201 and the base structure in the child seat 20, the locking assembly 203 may include multiple locking members, which may be located on the head side, back side, and leg side of the child seat 20. Corresponding to the multiple locking members, the first sensing assembly 500 may include multiple sensing portions. Specifically, the first support group 210 may be provided with a third sensing portion 510 corresponding to the locking member provided on the head side of the child seat 20, the second support group 220 may be provided with a fourth sensing portion 520 corresponding to the locking member provided on the back side of the child seat 20, and the third support group 230 may be provided with a fifth sensing portion 530 corresponding to the locking member provided on the leg side of the child seat 20. The third sensing portion 510 can sense the movement state of the locking piece provided on the head side of the child seat 20, the fourth sensing portion 520 can sense the movement state of the locking piece provided on the back side of the child seat 20, and the fifth sensing portion 530 can sense the movement state of the locking piece provided on the leg side of the child seat 20, thereby facilitating improvement in the detection accuracy of the detection jig 10 for detecting the connection state of each position of the child seat 20.

[0095] In some embodiments, reference Figure 11 and Figure 12The fourth support group 240 includes a first support block 241 and a second support block 242 respectively connected to the base 100. The first support block 241 and the second support block 242 are arranged relative to each other (the interval between the first support block 241 and the second support block 242 can be consistent with the distance between the handle end covers 204 on both sides of the child seat 20). The end of the first support block 241 away from the base 100 is provided with a first recess 2411, and the first recess 2411 is suitable for supporting the handle end cover 204 on one side of the child seat 20. The end of the second support block 242 away from the base 100 is provided with a second recess 2421, and the second recess 2421 is suitable for supporting the handle end cover 204 on the other side of the child seat 20; the first cylinder 310 is arranged between the first support block 241 and the second support block 242. The third support group 230 includes a third support block 231 connected to the base 100, a first support cantilever 232 connected to the third support block 231, and a second support cantilever 233 connected to the third support block 231. The first support cantilever 232 and the second support cantilever 233 are arranged at intervals from each other and jointly support the leg side of the child seat 20; the second cylinder 320 is arranged between the first support cantilever 232 and the second support cantilever 233.

[0096] Specifically, in this embodiment, the handle end cap 204 of the child seat 20 is generally circular in structure. To match the shape of the handle end cap 204, the first support block 241 is provided with a first recess 2411, and the second support block 242 is provided with a second recess 2421. The curvature of the first recess 2411 and the second recess 2421 can be consistent with the curvature of the handle end cap 204. When the child seat 20 is loaded onto the inspection jig 10, the handle end cap 204 on one side of the child seat 20 can be aligned with the first recess 2411 and snapped into the first recess 2411. The handle end cap 204 on the other side of the child seat 20 can be aligned with the second recess 2421 and snapped into the second recess 2421. Through the cooperation between the first recess 2411 and the handle end cover 204 on one side of the child seat 20, and through the cooperation between the second recess 2421 and the handle end cover 204 on the other side of the child seat 20, the positioning accuracy and positioning stability of the child seat 20 on the detection jig 10 can be improved, and the child seat 20 can be prevented from shifting during the detection process, thereby ensuring the detection accuracy of the detection jig 10 on the child seat 20.

[0097] In addition, when the child seat 20 is loaded onto the inspection jig 10, the leg side of the child seat 20 can maintain contact with the first support cantilever 232 and the second support cantilever 233. The leg side of the child seat 20 can be supported by the first support cantilever 232 and the second support cantilever 233 to ensure that the child seat 20 can be suspended in position.

[0098] In some embodiments, reference Figure 10 and Figure 11 The locking assembly 203 includes a rotating buckle 2031 located on the head side. The handle 202 drives the rotating buckle 2031 to rotate relative to the seat body 201. The rotating buckle 2031 includes a first rotating piece and a second rotating piece. The first support group 210 includes a fourth support block 211 and a fifth support block 212 respectively connected to the base 100. The fourth support block 211 and the fifth support block 212 are used to jointly support the head side of the child seat 20. The third sensing unit 510 includes a first distance sensor 511 and a second distance sensor 512. The first distance sensor 511 is connected to the fourth support block 211 for sensing the distance between the first rotating piece and the second distance sensor 512 is connected to the fifth support block 212 for sensing the distance between the second rotating piece and the first distance sensor.

[0099] Specifically, in this embodiment, when the child seat 20 is loaded onto the detection jig 10, the head side of the child seat 20 can maintain contact with the fourth support block 211 and the fifth support block 212, and the head side of the child seat 20 can be supported by the fourth support block 211 and the fifth support block 212. When the handle 202 is pulled, the first rotating piece and the second rotating piece can simultaneously rotate from the locked position to the unlocked position. At this time, the first distance sensor 511 can sense the change in distance between the first rotating piece and the second distance sensor 512 can sense the change in distance between the second rotating piece. The detection signals generated by the first distance sensor 511 and the second distance sensor 512 can detect whether the seat body 201 and the base structure can be disassembled normally. At the same time, providing two distance sensors to detect the two rotating pieces respectively can improve the detection accuracy of the detection jig 10.

[0100] In some embodiments, reference Figure 8 、 Figure 9 as well as Figure 11 The locking assembly 203 includes a first engaging protrusion 2032 and a second engaging protrusion 2033 located on the back side. The handle 202 drives the first engaging protrusion 2032 and the second engaging protrusion 2033 to move from a position extending from the seat body 201 to a position retracted within the seat body 201. The second support group 220 also includes a sixth support block 221 and a seventh support block 222. The fourth sensing portion 520 also includes a third distance sensor 521 and a fourth distance sensor 522. The third distance sensor 521 is connected to the sixth support block 221 for sensing the distance to the first engaging protrusion 2032. The fourth distance sensor 522 is connected to the seventh support block 222 for sensing the distance to the second engaging protrusion 2033.

[0101] Specifically, in this embodiment, when the child seat 20 is loaded onto the inspection jig 10, the back of the child seat 20 can maintain contact with the sixth support block 221 and the seventh support block 222, and the back of the child seat 20 can be supported by the sixth support block 221 and the seventh support block 222. In addition to the first and second rotating pieces provided on the head side of the child seat 20 to achieve the snap connection between the seat body 201 and the base structure, the first and second snap connection protrusions 2032 and 2033 provided on the back side of the child seat 20 can also achieve the snap connection between the seat body 201 and the base structure, thereby facilitating improved connection strength between the seat body 201 and the base structure. When handle 202 is pulled, first engaging protrusion 2032 and second engaging protrusion 2033 simultaneously move from a position extending from seat body 201 to a position retracted from seat body 201. At this time, third distance sensor 521 can sense the change in distance from first engaging protrusion 2032, while fourth distance sensor 522 can sense the change in distance from second engaging protrusion 2033. The detection signals generated by third distance sensor 521 and fourth distance sensor 522 can be used to detect whether the seat body 201 and the base structure are properly disassembled. Furthermore, providing two distance sensors to detect the two engaging protrusions, respectively, can improve the detection accuracy of detection jig 10.

[0102] In some embodiments, reference Figure 6 、 Figure 7 as well as Figure 11 The locking assembly 203 also includes a trigger 2034 located on the side of the leg. The trigger 2034 is driven by the pull handle 202 to rotate from the locked position to the unlocked position. The fifth sensing unit 530 includes a first through-beam sensor 531 and a second through-beam sensor 532. The first through-beam sensor 531 is configured to emit light, and the second through-beam sensor 532 is configured to receive the light emitted by the first through-beam sensor 531. When the trigger 2034 is in the locked position, it blocks the light emitted by the first through-beam sensor 531. When the trigger 2034 is in the unlocked position, it avoids the light emitted by the first through-beam sensor 531.

[0103] Specifically, in this embodiment, in addition to achieving a snap connection between the seat body 201 and the base structure via the first rotating piece and the second rotating piece provided on the head side of the child seat 20, and the first engaging protrusion 2032 and the second engaging protrusion 2033 provided on the back side of the child seat 20, the snap connection between the seat body 201 and the base structure can also be achieved via a trigger 2034 provided on the leg side of the child seat 20. The first and second rotating pieces, the first and second engaging protrusions 2032 and 2033, and the trigger 2034 enable a three-point positioning connection between the seat body 201 and the base structure, thereby further improving the connection strength between the seat body 201 and the base structure. When the child seat 20 is loaded onto the detection jig 10, the trigger 2034 is exactly located between the first matching sensor 531 and the second matching sensor 532. At this time, the light emitted by the first matching sensor 531 will be blocked by the trigger 2034, and the second matching sensor 532 cannot receive the light emitted by the first matching sensor 531, so that there is a first sensing state between the first matching sensor 531 and the second matching sensor 532. In the first sensing state, a stable connection between the seat body 201 and the base structure can be ensured. When the handle 202 is pulled, the trigger 2034 can be rotated from the locked position to the unlocked position. For example, the trigger 2034 will be tilted up. At this time, the trigger 2034 can avoid the position, and the light emitted by the first matching sensor 531 is no longer blocked by the trigger 2034. The second matching sensor 532 can receive the light emitted by the first matching sensor 531, so that there is a second sensing state between the first matching sensor 531 and the second matching sensor 532. In the second sensing state, normal disassembly between the seat body 201 and the base structure can be ensured.

[0104] With reference to the above embodiment, in the present application, the locking assembly 203 includes at least three types of locking members (including a first rotating plate and a second rotating plate provided on the head side of the child seat 20, a first engaging protrusion 2032 and a second engaging protrusion 2033 provided on the back side of the child seat 20, and a trigger 2034 provided on the leg side of the child seat 20), which is beneficial to improving the connection strength between the seat body 201 and the base structure and ensuring the connection stability between the seat body 201 and the base structure. Corresponding to the three types of locking members of the child seat 20, the detection fixture 10 is provided with three types of sensors, which can respectively detect the motion states of the three types of locking members through the three sensors, which is beneficial to improving the detection accuracy of the detection fixture 10 on the child seat 20.

[0105] In some embodiments, reference Figure 2 and Figure 3The detection fixture 10 further includes a sixth sensing portion 700, which is connected to the fourth support group 240 and is used to detect fasteners connected to the handle 205. The sixth sensing portion 700 is a metal sensor, which is used to detect screws connected to the handle 205 that are made of metal.

[0106] Specifically, in this embodiment, the connecting handle and the seat body 201 are generally connected via a metal screw. If the sixth sensing unit 700 does not detect the metal screw, then a connector is missing between the connecting handle and the seat body 201, and an effective connection between the connecting handle and the seat body 201 cannot be achieved. If the sixth sensing unit 700 detects the metal screw, then a connector is present between the connecting handle and the seat body 201, and an effective connection between the connecting handle and the seat body 201 can be achieved via the connector.

[0107] In some embodiments, reference Figure 4 and Figure 5 The detection fixture 10 further includes a seventh sensing portion 800 , which is connected to the fourth support group 240 for detecting the connecting handle 205 . The seventh sensing portion 800 is a distance sensor for sensing the distance between the seventh sensing portion 800 and the connecting handle 205 .

[0108] Specifically, in this embodiment, the seventh sensing portion 800 can detect whether the connection between the connecting handle 205 and the seat body 201 is secure. For example, an outward pulling force can be applied to the connecting handle 205. If the distance between the seventh sensing portion 800 and the connecting handle 205 does not change, the connection between the connecting handle 205 and the seat body 201 is secure. If the distance between the seventh sensing portion 800 and the connecting handle 205 changes, the connection between the connecting handle 205 and the seat body 201 is not secure.

[0109] In some embodiments, reference Figure 4 and Figure 5 The detection fixture 10 also includes a handle driving assembly 900, which includes a driving cylinder 910 and a driving rod 920 connected to the driving cylinder 910. The driving cylinder 910 is connected to the fourth support group 240. The driving cylinder 910 is used to drive the driving rod 920 to press the connecting handle 205 to cooperate with the seventh sensing unit 800 to sense the connection status of the connecting handle 205.

[0110] Specifically, in this embodiment, the drive rod 920 can apply an outward pulling force to the connecting handle. If the drive rod 920 is able to pull the connecting handle outward, that is, the distance between the seventh sensing portion 800 and the connecting handle 205 changes, then the connecting handle 205 and the seat body 201 are not securely connected. If the drive rod 920 is unable to pull the connecting handle outward, that is, the distance between the seventh sensing portion 800 and the connecting handle 205 does not change, then the connecting handle 205 and the seat body 201 are securely connected.

[0111] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship, movement, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly. When a directional reference is introduced in a specific embodiment, if the direction is not specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two directions parallel to each other and opposite to each other). Whether it is unidirectional or bidirectional is based on what a person of ordinary skill in the art can achieve. When the directional reference is bidirectional, it should be considered that two different embodiments are introduced in parallel.

[0112] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or", "and / or" or "and / or" appear in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0113] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
