[0029] Embodiments of the present application are described in detail below with reference to the attached drawings. The embodiments described below are examples of the present application and are not intended to limit the present application.

[0030] The detection equipment in the market is to move two sets of linear slide rails with a constant load, and the load is loaded on the seat cushion up and down. The existing detection equipment can only detect the seat body in the manufacturing process. When the seat is assembled on the vehicle, due to the problems such as personnel assembly omission and poor power line contact, the seat assembled on the vehicle may cause the safety belt unfastening reminder function to not work normally. Since the existing detection equipment cannot detect the seat assembled on the vehicle, the vehicle with the seat safety belt unfastening reminder function not working normally may flow into the market.

[0031] Reference will now be made to Figures 1-4 The detection device for detecting the seat safety belt unfastening reminder function according to the embodiment of the present application is described.

[0032] The detection device according to the embodiment of the present application comprises a detection assembly 100, which is the main functional part in the detection device. The detection assembly 100 comprises a mounting part 1 and an inflation detection column 2, wherein the inflation detection column 2 is arranged on the mounting part 1, and the mounting part 1 supports and positions the inflation detection column 2. The inflation detection column 2 has a deflated retracted state and an inflated elongated state. It can be understood that the inflation detection column 2 is an inflatable and deflatable part. When the inflation detection column 2 is in the retracted state, the volume of the inflation detection column 2 is small. When the inflation detection column 2 is in the elongated state, the inflation detection column 2 is filled with gas, and the volume of the inflation detection column 2 is large.

[0033] The detection device according to the embodiment of the present application can control the length and volume of the inflation detection column 2 by controlling the inflation amount, and can control the pressure applied by the inflation detection column 2 by controlling the inflation amount. When the inflation detection column 2 is inflated with less gas, the inflation detection column 2 has a small degree of expansion in the up-down direction, and the length of the inflation detection column 2 is short. When the inflation detection column 2 is inflated with more gas, the inflation detection column 2 has a large degree of expansion in the up-down direction, and the length of the inflation detection column 2 is long. When the inflatable length of the inflation detection column 2 reaches the maximum, the pressure inside the inflation detection column 2 can be increased by continuing to inflate the inflation detection column 2, and the pressure applied to the detection surface can be increased when the inflation detection column 2 abuts against the detection surface. Here, up and down are based on the orientation shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the inflation detection column must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0034] When the seat is installed on the vehicle body, due to the narrow internal space of the vehicle body and the obstruction of the top of the vehicle, the existing detection device cannot extend into the vehicle interior, and thus cannot detect the seat installed on the vehicle body. The inflation detection column 2 of the embodiment of the present application has a contracted state, and the volume of the inflation detection column 2 in the contracted state is small, the detection assembly 100 can be moved into the vehicle body from the vehicle door, for example, from the second-row side door of the vehicle, and is fitted in the internal space of the vehicle body, without interfering with the vehicle body, so as to avoid collision damage to the structure of the vehicle body and improve the use safety of the detection device.

[0035] After the inflation detection column 2 in the contracted state is moved into the internal space of the vehicle body, the inflation detection column 2 is inflated, and the inflation detection column 2 changes from the contracted state to the elongated state, so that the inflation detection column 2 can press the seat to simulate the state of a passenger sitting on the seat. When the seat belt unfastening reminder function is normal, the inflation detection column 2 presses the seat, and the seat belt unfastening reminder function will issue a reminder, indicating that the seat belt unfastening reminder function is normally operated; when the seat belt unfastening reminder function is invalid, the inflation detection column 2 presses the seat, and the seat belt unfastening reminder function will not issue a reminder, indicating that the seat belt unfastening reminder function is invalid, and thus the detection device of the present application completes the test.

[0036] After the detection is completed, the inflation detection column 2 is deflated, and the inflation detection column 2 changes from the elongated state to the contracted state, so that the volume of the inflation detection column 2 is reduced, and the inflation detection column 2 can be directly moved out from the vehicle door, and the post-detection work is quickly completed. The inflation detection column 2 in the contracted state not only facilitates storage, but also prepares for the next detection, thereby improving the working efficiency of the detection device.

[0037] After the inflation detection column 2 in the contracted state is moved into the internal space of the vehicle body, the inflation detection column 2 is inflated, and the inflation detection column 2 changes from the contracted state to the elongated state, so that the inflation detection column 2 extends in the up-down direction, and the upper end or the lower end of the inflation detection column 2 directly or indirectly presses on the seat, so as to press the seat.

[0038] When the inflation detection column 2 is in the elongated state, the mounting member 1 abuts against the roof of the vehicle, and the lower end of the inflation detection column 2 presses on the seat, and the upper end of the inflation detection column 2 abuts against the roof of the vehicle through the mounting member 1, so that the inflation of the inflation detection column 2 can increase the pressure in the inflation detection column 2, and the inflation detection column 2 can apply pressure to the seat to detect whether the seat belt unfastening reminder function is normally operated.

[0039] Alternatively, the upper end of the inflatable detection column 2 abuts against the roof and the mounting 1 presses on the seat, the upper end of the inflatable detection column 2 abuts against the roof, and the lower end of the inflatable detection column 2 presses on the seat through the mounting 1, so that the inflatable detection column 2 can apply pressure to the seat to detect whether the seat belt unfastening reminding function works normally. Alternatively, the upper end of the inflatable detection column 2 abuts against the roof and the lower end presses on the seat, and the inflatable detection column 2 can be inflated to increase the pressure inside the inflatable detection column 2, so that the inflatable detection column 2 can apply pressure to the seat to detect whether the seat belt unfastening reminding function works normally.

[0040] In addition, due to different types and sizes of vehicles, the distance from the seat to the roof is also different. In the detection device of the present application, the inflatable detection column 2 changes from the contracted state to the elongated state, and the inflatable detection column 2 telescopes in the up-down direction, and the extension size of the upper and lower ends of the inflatable detection column 2 is large, so that the inflatable detection column 2 can meet the use requirements of vehicles of various types and sizes, and improve the use range of the detection device. In addition, by adjusting the number of inflatable detection columns 2, multiple seats can be detected at the same time, which meets the use requirements of vehicles of various types such as five-seater and seven-seater vehicles.

[0041] According to the detection device of the embodiment of the present application, the inflatable detection column 2 in the contracted state is provided, which can be moved from the vehicle door into the vehicle body, and cooperates in the internal space of the vehicle body to detect the seat assembled on the vehicle body, reduces the risk that the vehicle with the seat belt unfastening reminding function not working normally circulates to the market, and the detection device does not interfere with the vehicle body, avoids collision damage to the structure of the vehicle body, and improves the use safety of the detection device.

[0042] In some embodiments of the present application, as shown in Figure 2 The inflatable detection column 2 is in the form of a cylinder, avoiding stress concentration points when the inflatable detection column 2 is inflated, and improving the use safety of the detection device.

[0043] It is worth noting that the inflatable detection column 2 in the embodiment of the present application is one-to-one with the seat, and one inflatable detection column 2 is suitable for applying pressure to one seat, which improves the detection accuracy of the detection device.

[0044] In some embodiments of the present application, the detection assembly 100 includes at least two mountings 1, and the adjacent two mountings 1 are connected through a connecting piece 3. At least one inflatable detection column 2 is connected to each mounting 1, and the connecting piece 3 connects the plurality of mountings 1 into one body, so that the detection assembly 100 can detect at least two seats at the same time, improving the working efficiency of the detection device. The detection device of the embodiment of the present application not only can detect the seat assembled on the vehicle body, but also can detect multiple seats at the same time, improving the detection efficiency.

[0045] Optionally, a plurality of mounting members 1 are included in the detection assembly 100, and one inflation detection column 2 is arranged on each mounting member 1, that is, the inflation detection column 2 is arranged in one-to-one correspondence with the mounting member 1, and the detection assembly 100 can simultaneously detect a plurality of seats. Alternatively, a plurality of inflation detection columns 2 are connected to the mounting member 1 in the detection assembly 100 to detect a plurality of seats, which all fall within the protection scope of the present application.

[0046] In some embodiments, the detection assembly 100 can simultaneously detect a plurality of automobile seats located in the same row, for example, the second row of seats of the automobile seats is three seats arranged adjacently (applicable to a 5-seater vehicle), the detection assembly 100 can include three mounting members 1, and one inflation detection column 2 is connected to each mounting member 1, so that the detection assembly 100 can simultaneously detect all the seats in the second row of seats, improving the working efficiency of the detection device.

[0047] In other embodiments, the detection assembly 100 can simultaneously detect automobile seats located in different rows, for example, the detection assembly 100 can include two mounting members 1, and one inflation detection column 2 is connected to each mounting member 1, so that the detection assembly 100 can simultaneously detect the first row of seats and the second row of seats, or the detection assembly can simultaneously detect the second row of seats and the third row of seats (applicable to a 7-seater vehicle), improving the working efficiency of the detection device.

[0048] In still other embodiments, the detection assembly 100 can also simultaneously detect a plurality of automobile seats located in different rows, for example, the first row of seats of the automobile seats has two seats, the second row of seats of the automobile seats has two seats, the detection assembly 100 can include four mounting members 1, and one inflation detection column 2 is connected to each mounting member 1, so that the detection assembly 100 can simultaneously detect the two seats in the first row of seats and the two seats in the second row of seats, improving the working efficiency of the detection device.

[0049] In some embodiments of the present application, the connecting member 3 is a deformable member, and when the inflation detection column 2 is in a contracted state, the adjacent two mounting members 1 are stacked by deforming the deformable member. By arranging the connecting member 3, the detection assembly 100 can be stacked, further reducing the volume of the detection assembly 100, that is, even if the detection assembly 100 includes two or more mounting members 1, the detection assembly 100 can enter or move out of the vehicle body through the vehicle door, without interfering with the vehicle body, which can avoid collision damage to the vehicle body structure, improving the use safety of the detection device.

[0050] In some embodiments of the present application, the connecting member 3 comprises at least two branches 30, each of the branches 30 has a center end and a terminal end, the center ends of the at least two branches 30 are connected, the terminal ends of each of the branches 30 are connected to the mounting members 1, and the thickness of each of the branches 30 gradually decreases from the terminal end to the center end. The connecting member 3 can be bent at the connection of the center ends as the center of motion to drive the mounting members 1 connected to the terminal ends to be stacked with each other, so as to reduce the volume of the detection assembly 100. The detection assembly 100 can be moved from the door of the vehicle into the vehicle body to simultaneously detect a plurality of seats assembled on the vehicle body, or the detection assembly 100 can be quickly moved from the vehicle body out of the door of the vehicle, so as to improve the working efficiency of the detection device.

[0051] In some specific embodiments of the present application, as shown in Figure 1 and Figure 2 , the connecting member 3 comprises two branches 30, i.e. a first branch 3a and a second branch 3b, the terminal ends of the first branch 3a and the second branch 3b have the maximum thickness, the center ends of the first branch 3a and the second branch 3b have the minimum thickness, the thickness gradually decreases from the terminal end to the center end, and the cross-sectional shape of the first branch 3a and the second branch 3b is trapezoidal. The center ends of the first branch 3a and the second branch 3b are connected, and the terminal ends of the first branch 3a and the second branch 3b are connected to the mounting members 1. The connecting member 3 is bent at the connection of the first branch 3a and the second branch 3b as the center of motion to drive the terminal ends of the first branch 3a and the second branch 3b to be close to each other, so as to stack the mounting members 1 with each other.

[0052] In some specific embodiments of the present application, the connecting member 3 comprises two branches 30, i.e. a third branch and a fourth branch, the thickness of the third branch and the fourth branch gradually decreases from the terminal end to the center end, and the surface of the connecting member 3 from the terminal end of the third branch to the terminal end of the fourth branch is an arc-shaped curved surface, which avoids the branches 30 from being broken due to multiple folding and prolongs the service life of the connecting member 3.

[0053] In some embodiments of the present application, as shown in Figure 2 , the detection assembly 100 comprises at least two rows of mounting members 1 arranged in front and back, each row comprises at least two mounting members 1, and the detection assembly 100 can simultaneously detect a plurality of automobile seats located in different rows, so as to improve the working efficiency of the detection device.

[0054] As shown in Figure 1 and Figure 2As shown, the connecting piece 3 comprises a first connecting piece 31, the front and rear rows of mounting pieces 1 are connected through the first connecting piece 31, and the first connecting piece 31 connects all the mounting pieces 1 in the same row. Alternatively, the first connecting piece 31 is a deformable piece, when the inflatable detection column 2 is in the contracted state, the front and rear rows of mounting pieces 1 can be stacked by deforming the first connecting piece 31, thereby reducing the width dimension of the detection assembly 100. It is convenient to move the detection assembly 100 from the door of the vehicle into the vehicle body, which can avoid collision damage to the vehicle body structure, not only can detect the seat assembled on the vehicle body, but also can detect multiple seats at the same time, which improves the use safety of the detection device while improving the detection efficiency.

[0055] As shown in Figure 1 and Figure 3 The connecting piece 3 also comprises a second connecting piece 32, and the adjacent mounting pieces 1 in the same row are connected through the second connecting piece 32. The connecting piece 3 connects multiple mounting pieces 1 into one, the second connecting piece 32 connects adjacent mounting pieces 1 into a row, and the first connecting piece 31 connects adjacent two rows of mounting pieces 1 to each other, thereby improving the integrity of the detection assembly 100. When the detection assembly 100 is used for detection, the whole detection assembly 100 can be directly moved from the door of the vehicle into the vehicle body for detection, without having to drive multiple detection assemblies 100 for detection step by step, thereby improving the working efficiency of the detection device.

[0056] Alternatively, the second connecting piece 32 is a deformable piece, and when the inflatable detection column 2 is in the contracted state, the mounting pieces 1 connected in the same row can be stacked by deforming the second connecting piece 32, thereby reducing the length dimension of the detection assembly 100. Not only is it convenient for the detection assembly 100 to move through the door, but also it is convenient for the storage of the detection assembly 100, thereby reducing the space occupied by the detection assembly 100.

[0057] Alternatively, the second connecting piece 32 is a shape-fixed piece, and the second connecting piece 32 fixedly connects the adjacent two mounting pieces 1 in the same row, so as to ensure the spacing of the adjacent two mounting pieces 1 in the same row. Since the inflatable detection column 2 and the seat are one-to-one arranged, the fixed spacing of the mounting piece 1 can reduce the occurrence of position deviation when the inflatable detection column 2 changes from the contracted state to the elongated state, thereby improving the detection accuracy of the detection device.

[0058] In other embodiments of the present application, the detection assembly 100 comprises two mounting pieces 1 arranged in front and rear rows, and a plurality of inflatable detection columns 2 are connected to each mounting piece 1. The plurality of inflatable detection columns 2 are arranged at intervals along the length direction of the mounting piece 1, and the two mounting pieces 1 are connected through a connecting piece 3. The spacing between the plurality of inflatable detection columns 2 on the same mounting piece 1 is fixed, which can reduce the occurrence of deviation when the inflatable detection column 2 changes from the contracted state to the elongated state, thereby improving the detection accuracy of the detection device.

[0059] In some embodiments of the present application, as shown in Figures 1-3 The detection assembly 100 further comprises a foot 4 connected to the lower end of the inflatable detection column 2, and the cross-sectional area of the foot 4 in contact with the seat is larger than that of the inflatable detection column 2. After the inflatable detection column 2 in the contracted state is moved into the vehicle body, the inflatable detection column 2 is inflated, and the inflatable detection column 2 changes from the contracted state to the elongated state, and the inflatable detection column 2 extends in the up-down direction, and the lower end of the inflatable detection column 2 is pressed on the seat through the foot 4, so that the seat can be pressed, and the cross-sectional area of the foot 4 is large, the pressing area of the seat is large, and the situation that the safety belt reminder function does not work normally due to the fact that the force point is not detected to press can be avoided, and the detection accuracy of the detection device can be improved.

[0060] It is worth noting that the detection assembly 100 contacts the seat through the foot 4, and the inflatable detection column 2 only provides pressure, so the cross-sectional area of the inflatable detection column 2 can be reduced, which not only reduces the manufacturing cost, but also reduces the volume of the detection assembly 100, facilitates the detection assembly 100 to enter or move out of the vehicle body through the vehicle door, and improves the use safety of the detection device.

[0061] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The foot 4 is configured as a circular truncated cone, the upper end of the foot 4 is connected to the inflatable detection column 2, the diameter of the upper end surface of the foot 4 is the same as that of the inflatable detection column 2, the diameter of the lower end surface of the foot 4 is larger than that of the upper end surface of the foot 4, and the cross-sectional area of the foot 4 gradually increases in the direction from top to bottom.

[0062] In some embodiments of the present application, as shown in Figure 2 and Figure 3 The detection assembly 100 further comprises a limiting plate 5 connected to the mounting member 1, and the limiting plate 5 covers at least one side of the inflatable detection column 2 in the horizontal direction in the inflated state. The inflatable detection column 2 changes from the contracted state to the elongated state, and the inflatable detection column 2 extends in the up-down direction, and it can be understood that when the inflatable detection column changes to the elongated state, the inflatable detection column has the risk of displacement, which is easy to cause the situation that the detection assembly does not press the force point of the seat, and reduces the accuracy of the detection result of the detection assembly. By providing the limiting plate 5, the guiding and limiting effects of the limiting plate 5 on the inflatable detection column 2 can be achieved, the situation that the position of the inflatable detection column 2 deviates when the inflatable detection column 2 changes from the contracted state to the elongated state can be avoided, and the detection accuracy of the detection device can be improved.

[0063] In some specific embodiments of the present application, the limiting plate 5 is arranged in one-to-one correspondence with the inflation detection column 2, the limiting plate 5 is connected to the bottom of the mounting piece 1, and the limiting plate 5 is a limiting ring arranged in the up-down direction. The upper end of the inflation detection column 2 is connected to the mounting piece 1 and the lower end is connected to the pressing foot 4, the limiting ring is sleeved outside the inflation detection column 2, when the inflation detection column 2 is in the contracted state, a part of the inflation detection column 2 is shrunk in the limiting ring, and the pressing foot 4 abuts against the lower end of the limiting ring; when the inflation detection column 2 is in the elongated state, the limiting ring is sleeved outside the inflation detection column 2 in the horizontal direction. The upper end of the limiting ring is connected to the mounting piece 1, and the connection between the limiting ring and the mounting piece 1 is wrapped outside the connection between the upper end of the inflation detection column 2 and the mounting piece 1. The limiting ring plays a guiding and limiting role on the inflation detection column 2, and when the inflation detection column 2 changes from the contracted state to the elongated state, it is elongated in the up-down direction. The inflation detection column 2 presses against the seat, which can improve the detection accuracy of the detection device.

[0064] In some embodiments of the present application, the mounting piece 1 is a foamed piece, which is light in weight and soft in texture. When the inflation detection column 2 abuts against the roof of the vehicle through the mounting piece 1, damage to the roof of the vehicle can be avoided, and the use safety of the detection assembly 100 is improved. The mounting piece 1 is light in weight, which facilitates the movement and use of the detection assembly 100.

[0065] In some specific embodiments of the present application, the mounting piece 1 is a foam filling piece.

[0066] In some embodiments of the present application, a part of the inflation detection column 2 is located in the foamed piece, the inflation port of the inflation detection column 2 is located on the mounting piece 1, airflow enters the inflation detection column 2 through the inflation port to make the inflation detection column 2 change from the contracted state to the elongated state. The airflow can also be discharged from the inflation detection column 2 through the inflation port to make the inflation detection column 2 change from the elongated state to the contracted state.

[0067] In some embodiments of the present application, the detection device further comprises a gas source, which inflates the inflation port of the inflation detection column 2 to make the inflation detection column 2 change from the contracted state to the elongated state. Optionally, the gas source comprises a gas pump, which selectively inflates the inflation detection column 2 to make the inflation detection column 2 change from the contracted state to the elongated state.

[0068] Optionally, the gas source is in common communication with the inflation ports of a plurality of inflation detection columns 2, and the gas source can simultaneously inflate a plurality of inflation detection columns 2, so that the plurality of inflation detection columns 2 collectively change from the contracted state to the elongated state. The detection assembly 100 simultaneously detects a plurality of seats, which improves the detection efficiency.

[0069] Optionally, the air source is in communication with the inflation ports of the plurality of inflatable detection columns 2 respectively. When a certain inflatable detection column 2 is damaged, the inflation port of the inflatable detection column 2 can be isolated, and the rest of the inflatable detection columns 2 can be in the normal contracted state and changed to the elongated state to perform detection. Alternatively, the detection assembly 100 can change the number of seats to be detected, thereby improving the use range of the detection device. For example, the detection assembly 100 includes three inflatable detection columns 2, which can simultaneously detect three seats; by isolating the inflation port of one of the inflatable detection columns 2, the detection assembly 100 can be used to detect two seats.

[0070] In some embodiments of the present application, the detection device further comprises a mechanical arm, the execution end of the mechanical arm is connected to the detection assembly 100, and the mechanical arm is used to drive the detection assembly 100 to enter and exit the vehicle from the door of the vehicle. The detection assembly 100 is an integral whole, and the mechanical arm can drive the detection assembly 100 to enter the vehicle to simultaneously detect multiple seats. After the detection is completed, the mechanical arm can drive the detection assembly 100 to move out from the door to prepare for the next detection. By setting the mechanical arm, the mechanical movement of the detection assembly 100 can be realized, and the detection device can cooperate with the assembly line of the vehicle. After the seat is assembled on the vehicle, the detection device can detect the seat belt unfastening reminding function, thereby improving the work efficiency.

[0071] Optionally, the execution end of the mechanical arm clamps the center end of the plurality of branches 30 of the connecting piece 3. The mechanical arm not only can drive the detection assembly 100 to enter and exit the vehicle from the door of the vehicle, but also can drive the connecting piece 3 to drive the mounting pieces 1 to be stacked on each other, thereby reducing the volume of the detection assembly 100 and facilitating the detection assembly 100 to enter and exit the vehicle from the door of the vehicle.

[0072] In some specific embodiments of the present application, a gas pump is installed on the mechanical arm, and the gas pump is in selective communication with the inflation ports of the inflatable detection columns 2. The mechanical arm is connected to the detection assembly 100, and the detection of the detection device can be completed.

[0073] In the initial stage, the inflatable detection columns 2 in the detection assembly 100 are in the contracted state, and the mechanical arm drives the mounting pieces 1 to be stacked on each other, so that the volume of the detection assembly 100 is the smallest. Next, the mechanical arm drives the detection assembly 100 to enter the vehicle body from the door of the vehicle, and then the mechanical arm drives the connecting piece 3 to move to expand the mounting pieces 1, so that the inflatable detection columns 2 are arranged one by one corresponding to the seats. Then, the gas pump inflates the inflatable detection columns 2, and the plurality of inflatable detection columns 2 collectively change from the contracted state to the elongated state. The inflatable detection columns 2 can press the seats to simulate the state that the passengers sit on the seats, thereby detecting the seat belt unfastening reminding function.

[0074] When the detection is completed, the inflatable detection column 2 is deflated, and changes from the extended state to the contracted state. Then the mechanical arm drives the mounting members 1 to be stacked on each other, and the volume of the detection assembly 100 is reduced again. Then the mechanical arm drives the detection assembly 100 to move out of the vehicle from the vehicle door, to prepare for the next detection.

[0075] The structure and working process of the detection device in one specific embodiment of the present application are described in detail below. Figures 1-4 The structure and working process of the detection device in one specific embodiment of the present application are described in detail below.

[0076] In the present embodiment, the detection device is used to detect a seven-seat vehicle, the main driver seat and the co-driver seat are the first-row seats, the second-row seats include two seats arranged at intervals, and the third-row seats include three seats. In the present embodiment, the detection device detects the second-row seats and the third-row seats of the vehicle.

[0077] The detection device includes a detection assembly 100 and a mechanical arm for driving the detection assembly 100 to move. The detection assembly 100 includes mounting members 1 and inflatable detection columns 2, the upper ends of the inflatable detection columns 2 are connected with the mounting members 1, and the inflatable detection columns 2 are arranged one by one with the mounting members 1. The inflatable detection columns 2 have a contracted state when not inflated and an extended state when inflated, and when the inflatable detection columns 2 change from the contracted state to the extended state, the inflatable detection columns 2 stretch towards the lower side, and the inflatable detection columns 2 can press the seats to simulate the state of passengers sitting on the seats.

[0078] The detection assembly 100 includes two rows of mounting members 1 arranged in front and back, the first row of mounting members includes a first mounting member 11 and a second mounting member 12 connected with each other, and the second row of mounting members includes a third mounting member 13, a fourth mounting member 14 and a fifth mounting member 15 connected in sequence. Correspondingly, the inflatable detection columns 2 are also five, the first mounting member 11 is connected with a first inflatable detection column 21 below, the second mounting member 12 is connected with a second inflatable detection column 22 below, the third mounting member 13 is connected with a third inflatable detection column 23 below, the fourth mounting member 14 is connected with a fourth inflatable detection column 24 below, and the fifth mounting member 15 is connected with a fifth inflatable detection column 25 below. Among them, the fourth inflatable detection column 24 is a separately contractible or foldable member, when the third-row seats include three seats, the fourth inflatable detection column 24 normally works; when the third-row seats include two seats, the fourth inflatable detection column 24 is always in the contracted state and does not inflate. The fourth inflatable detection column 24 can flexibly adjust the contracted state and the extended state according to the number of seats in the third-row seats, so that one detection assembly can be used to detect vehicles with various seat arrangements.

[0079] The first row of mounting members and the second row of mounting members are connected by the connecting member 3, the connecting member 3 comprises two branches 30, namely a first branch 3a and a second branch 3b, and each branch 30 has a center end and a terminal end. The terminal end of the first branch 3a is connected with all the mounting members 1 of the first row of mounting members, the terminal end of the second branch 3b is connected with all the mounting members 1 of the second row of mounting members, the center end of the first branch 3a and the center end of the second branch 3b are connected, and the thickness of the branch 30 gradually decreases from the terminal end to the center end. The connecting member 3 can be bent at the connection of the first branch 3a and the second branch 3b as the center of motion to drive the first row of mounting members and the second row of mounting members to overlap each other. The end of the mechanical arm clamps the connection of the center end of the first branch 3a and the center end of the second branch 3b of the connecting member 3.

[0080] The detection assembly 100 further comprises a presser foot 4, the presser foot 4 is arranged one-to-one with the inflation detection column 2, the presser foot 4 is connected to the lower end of the inflation detection column 2, and the cross-sectional area of the presser foot 4 is greater than that of the inflation detection column 2. The detection assembly 100 further comprises a limiting plate 5, the limiting plate 5 is arranged one-to-one with the inflation detection column 2, and the limiting plate 5 is connected to the bottom of the mounting member 1. The limiting plate 5 is a limiting ring extending in the up-down direction, and the limiting ring is sleeved outside the inflation detection column 2.

[0081] In the embodiment, the detection device detects the second row of seats and the third row of seats of the vehicle. In the initial stage, all the inflation detection columns 2 in the detection assembly 100 are in the contracted state, and the mechanical arm drives the connecting member 3 to bend at the connection of the first branch 3a and the second branch 3b as the center of motion to drive the first row of mounting members and the second row of mounting members to overlap each other, at this time, the volume of the detection assembly 100 is the smallest.

[0082] Next, the mechanical arm drives the detection assembly 100 to enter the vehicle body from the rear door of the vehicle. In the embodiment of the application, the detection device detects the second row of seats and the third row of seats of the vehicle, the rear door of the vehicle is closest to the second row of seats and the third row of seats, and the space of the rear door is relatively large, so the detection assembly 100 is arranged to enter the vehicle body from the rear door of the vehicle.

[0083] Then, the mechanical arm drives the connecting member 3 to move to unfold the first row of mounting members and the second row of mounting members, so that the inflation detection columns 2 are arranged one-to-one opposite to the seats in the up-down direction, that is, the first inflation detection column 21 and the second inflation detection column 22 are opposite to the second row of seats, and the third inflation detection column 23, the fourth inflation detection column 24 and the fifth inflation detection column 25 are opposite to the third row of seats.

[0084] Then the air source inflates the inflatable detection column 2, and the plurality of inflatable detection columns 2 jointly change from the contracted state to the elongated state. The inflatable detection column 2 stretches in the up-down direction, the mounting piece 1 at the upper end of the inflatable detection column 2 abuts against the roof, and the pressure foot 4 at the lower end of the inflatable detection column 2 abuts against the seat. The inflatable detection column 2 continues to be inflated, the pressure in the inflatable detection column 2 is increased, and the inflatable detection column 2 can apply pressure to the seat to simulate the state that the passenger is seated on the seat. When the seat belt unfastening reminding function is normal, the inflatable detection column 2 applies pressure to the seat, the seat belt unfastening reminding function sends a reminder, and it is indicated that the seat belt unfastening reminding function is in normal operation. When the seat belt unfastening reminding function is invalid, the inflatable detection column 2 applies pressure to the seat, the seat belt unfastening reminding function does not send a reminder, and it is indicated that the seat belt unfastening reminding function is invalid. The detection device of the application thus completes the test.

[0085] In the embodiment, the detection device can not only detect the seat assembled to the vehicle body, but also simultaneously detect the five seats of the second-row seat and the third-row seat, thereby improving the working efficiency of the detection device.

[0086] After the detection is completed, the inflatable detection column 2 is deflated, and changes from the elongated state to the contracted state. Then the mechanical arm drives the connecting piece 3 to deform, drives the first-row mounting piece 1 and the second-row mounting piece 1 to be stacked with each other, and the volume of the detection assembly 100 is reduced again. Then the mechanical arm drives the detection assembly 100 to move out of the vehicle from the rear door of the vehicle to prepare for the next detection.
