[0054] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0056] As shown in the background technology, in the prior art, when measuring the closing force of a sliding door, a staff member needs to hold a closing force tester, place one end of the closing force tester against the door frame, push the door panel so that the door panel hits the measuring end of the closing force tester, and read the indication on the closing force tester to complete a closing force test.

[0057] In actual measurement, in order to ensure the accuracy of the measurement, it is also necessary to adjust the height of the closing force tester so that the door panel hits multiple times, obtain multiple sets of data, and analyze the measured data to detect whether the sliding doors on the railway train meet the safety standards.

[0058] However, the sliding doors inside some trains are set as curved doors, such as the toilet doors inside some trains, with curved rails set under the door panels, and the door panels are curved with the same curvature, and the door panels slide along the rails to open and close. For this type of door, the direction of impact between the door panel and the door frame is not parallel to the plane where the door frame is located. Therefore, when performing the closing force test, the staff cannot just put the bottom of the closing force tester close to the door frame, but also need to manually tilt the closing force tester to make the closing force tester collide with the door panel as much as possible.

[0059] However, it is difficult to fix the handheld closing force tester at a specific angle, so it is difficult for the door panel to collide with the closing force tester, resulting in large errors in the measurement results. In addition, when performing multiple measurements, the handheld closing force tester cannot guarantee that the closing force tester is placed at the same angle for each test, so the multiple sets of data obtained have large deviations, affecting the accuracy of the measurement results.

[0060] In view of the above technical problems, an embodiment of the present application provides a closing force testing device, including a fixed seat, a movable seat, a locking assembly and a measuring assembly. The fixed portion of the fixed seat is fixed to the door frame, the second adjusting portion of the movable seat is hinged to the first adjusting portion of the fixed seat and fixed by the locking assembly, and the measuring assembly is installed on the mounting portion of the movable seat. When performing a closing force test, the second adjusting portion is rotated relative to the first adjusting portion to adjust the angle between the movable seat and the fixed seat until the measuring assembly on the movable seat is consistent with the impact direction of the door panel, and then the movable seat and the fixed seat are kept at the current angle by the locking assembly, and the door panel is pushed to make it collide with the measuring assembly, and a closing force test can be completed. In this way, it can be ensured that the measuring assembly is maintained at a fixed angle and collides with the door panel each time the closing force test is performed, thereby reducing the error during measurement and improving the accuracy of the closing force test.

[0061] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0062] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the closing force testing device of the embodiment of the present application includes a fixed seat 100, a movable seat 200, a locking assembly 300 and a measuring assembly 400; the fixed seat 100 is provided with a fixing portion 110 and a first adjusting portion 120, and the fixing portion 110 is used to connect with the door frame; the movable seat 200 is provided with a mounting portion 210 and a second adjusting portion 220; the second adjusting portion 220 and the first adjusting portion 120 are hinged, and the locking assembly 300 is configured to connect the second adjusting portion 220 and the first adjusting portion 120 so that the movable seat 200 and the fixed seat 100 maintain a current angle; the measuring assembly 400 is arranged on the mounting portion 210, and the measuring assembly 400 is used to withstand the impact of the door panel to measure the closing force of the door panel.

[0063] In the present application, the fixed seat 100 is connected to the door frame through the fixed portion 110, and the second adjustment portion 220 is hinged to the first adjustment portion 120, so that the movable seat 200 is connected to the fixed seat 100, and the angle between the movable seat 200 and the fixed seat 100 is maintained by the locking assembly 300, and the measuring assembly 400 is fixed to the mounting portion 210 of the movable seat 200. The connection between the fixed portion 110 and the door frame can be achieved by fixing the fixed portion 110 to the door frame by means of snap connection, etc., or a plane can be set, and the staff can hold the closing force test device so that the plane is always close to the door frame. The specific connection method is not limited in this application.

[0064] When conducting a closing force test, first connect the fixing portion 110 to the door frame, and install the measuring assembly 400 on the mounting portion 210. Then adjust the angle between the movable seat 200 and the fixed seat 100 so that the extension direction of the measuring assembly 400 is consistent with the impact direction of the door panel. Then connect the first adjustment portion 120 and the second adjustment portion 220 through the locking assembly 300 so that the current angle between the movable seat 200 and the fixed seat 100 is maintained. Finally, push the door panel so that it hits the measuring assembly 400 to complete a measurement.

[0065] In this way, the direction of the measuring component 400 can be flexibly adjusted according to the impact direction of the door panel, and the fixed seat 100 and the movable seat 200 can be locked by the locking component 300 to keep the measuring component 400 at a fixed angle, thereby avoiding the problem of difficulty in maintaining stability when holding the test device, ensuring that the door panel hits the measuring component 400 head-on, effectively reducing the measurement error, and providing accuracy in closing force measurement.

[0066] In addition, when actually measuring the closing force, multiple measurements are required and multiple sets of data are analyzed to ensure the accuracy of the measurement. When using the closing force testing device of this embodiment for testing, the locking assembly 300 maintains the angle between the movable seat 200 and the fixed seat 100 at a specific angle. No matter how the height of the fixed seat 100 relative to the ground is changed, the angle of the measuring assembly 400 will not change, thereby ensuring that the angle of the measuring assembly 400 is the same each time the measurement is taken, avoiding excessive differences between multiple sets of data, and further improving the accuracy of the closing force measurement.

[0067] Among them, both the fixed seat 100 and the movable seat 200 can be made of wood to reduce the weight of the closing force testing device, avoid sliding during the measurement process, and ensure the stability of the connection between the fixed seat 100 and the door panel. The specific material is not limited in this application.

[0068] In some possible implementations, see Figure 3 , Figure 4 and Figure 5 As shown, the first adjustment part 120 of the embodiment of the present application is an arc-shaped groove, and the second adjustment part 220 is an arc-shaped protrusion; the center of the arc-shaped groove is located outside the arc-shaped groove, and the center of the arc-shaped protrusion is located outside the arc-shaped protrusion; the arc-shaped groove and the arc-shaped protrusion have the same curvature, and the arc-shaped protrusion is located in the arc-shaped groove; an arc-shaped through hole 121 is provided at the bottom of the arc-shaped groove, and an eccentric hole 221 is provided on the arc-shaped protrusion; the locking assembly 300 passes through the eccentric hole 221 and the arc-shaped through hole 121 in sequence to lock the angle between the movable seat 200 and the fixed seat 100.

[0069] In some embodiments, the first adjustment portion 120 is an arc-shaped groove, the second adjustment portion 220 is an arc-shaped protrusion matching the arc-shaped groove, and the arc-shaped groove and the arc-shaped protrusion are both set to be minor arcs. In this way, the distance between the measuring component 400 and the door frame can be reduced, thereby reducing the measurement error of the closing force.

[0070] Furthermore, an arc-shaped through hole 121 is provided at the bottom of the arc-shaped groove, and an eccentric hole 221 is provided on the arc-shaped protrusion. During actual measurement, the locking assembly 300 passes through the eccentric hole 221 and the arc-shaped through hole 121 in sequence. When adjusting the angle between the movable seat 200 and the fixed seat 100, the fixed seat 100 is connected to the door frame and remains stationary. It is necessary to rotate the second adjustment part 220 with the locking assembly 300 as the axis relative to the fixed seat 100 to a suitable angle, and then slide along the arc-shaped through hole 121 with the locking assembly 300 until the arc-shaped protrusion can be embedded in the arc-shaped groove, and finally lock the relative position between the movable seat 200 and the fixed seat 100 through the locking assembly 300. In this way, it is ensured that the movable seat 200 and the fixed seat 100 can make the arc-shaped protrusion embedded in the arc-shaped groove under different angles, and the stability of the locking assembly 300 locking the movable seat 200 and the fixed seat 100 is guaranteed, thereby improving the measurement accuracy of the closing force test device.

[0071] In some possible implementations, see Figure 4 As shown, a first card slot 111 is provided on the fixing portion 110 of the embodiment of the present application, and the first card slot 111 is used for card connection with the door frame.

[0072] It can be understood that a first card slot 111 is provided on the fixing portion 110, and the fixing base 100 is installed on the door frame by snapping the first card slot 111 with the door frame. The first card slot 111 can be set to completely match the shape of the door frame and can be directly fixed to the door frame by snapping, or it can be set to a card slot with adjustable size so that the closing force testing device can be fixed on different types of door frames, thereby expanding its scope of application.

[0073] In some possible implementations, see Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, an installation groove 211 is provided on the installation portion 210 of the embodiment of the present application, and the measuring component 400 includes a shell 410, a limit block 420 and a closing force tester 430; the limit block 420 and a part of the shell 410 are both located in the installation groove 211 and connected to the installation groove 211, and the limit block 420 is arranged in the shell 410; the closing force tester 430 includes a tester body 431 and a force measuring screw 432 arranged on the tester body 431, the tester body 431 is fixedly connected to the shell 410, and one end of the tester body 431 away from the force measuring screw 432 abuts against the limit block 420, and the force measuring screw 432 is used to withstand the impact of the door panel.

[0074] It should be noted that the housing 410 provides an installation space for the closing force tester 430, and the housing 410 is partially connected to the installation slot 211, and the closing force tester 430 is fixed on the housing 410, so that the angle of the closing force tester 430 can change with the change of the movable seat 200, and the housing 410 can also protect the closing force tester 430. Among them, the housing 410 can be made of carbon steel to reduce the probability of deformation and increase its service life. The specific material of the housing 410 is not limited in this application.

[0075] In addition, a limit block 420 is provided between the closing force tester 430 and the mounting groove 211 of the movable seat 200. One side of the limit block 420 abuts against the tester body 431, and the opposite side abuts against the mounting groove 211, thereby preventing the tester body 431 from moving when the force measuring screw 432 of the closing force tester 430 is impacted, thereby affecting the accuracy of the measurement result. The limit block 420 can be made of a material with a high hardness such as aluminum to reduce the possibility of deformation due to impact and improve the accuracy of the measurement of the closing force test device.

[0076] In some possible implementations, see Figure 5 and Figure 6 As shown, a second slot 421 is formed at one end of the limit block 420 facing away from the closing force tester 430 of the embodiment of the present application, and a block 212 is disposed in the installation slot 211 , and the block 212 is engaged with the second slot 421 .

[0077] In some embodiments, a second slot 421 is provided on the limit block 420, and the second slot 421 is engaged with the block 212 of the installation slot 211 to ensure the stability of the connection between the limit block 420 and the installation slot 211, thereby preventing the limit block 420 from moving during the impact of the door panel.

[0078] In addition, the second card slot 421 can also be set to match the shape of the door frame. In this way, when the door to be tested is an ordinary flat sliding door, there is no need to adjust the angle of the measuring component 400. The movable seat 200 and the fixed seat 100 can be removed, and the second card slot 421 can be directly connected to the door frame for measurement, which is beneficial to improving the convenience of using the closing force testing device.

[0079] In some possible implementations, see Figure 1 , Figure 2 and Figure 6 As shown, the measuring component 400 of the embodiment of the present application also includes a load-bearing block 440, one end of which is connected to the force measuring screw 432, and the other end of the load-bearing block 440 is provided with a load-bearing groove 441, and the load-bearing groove 441 is used to match the shape of the side of the door panel.

[0080] It is understandable that a bearing block 440 is installed on the force measuring screw 432, and a bearing groove 441 matching the shape of the door panel is provided on the bearing block 440, so that the force bearing area and force range can be increased when the door panel hits the closing force tester 430, and the bearing block 440 transmits the impact force to the force measuring screw 432, which is conducive to further improving the accuracy of the closing force tester in measuring the closing force. The bearing block 440 can be made of a material with higher hardness, such as aluminum, which can better transmit the force to the force measuring screw 432 on the one hand, and avoid damage after being hit by the door panel on the other hand, thereby increasing its service life.

[0081] In some possible implementations, see Figure 2 and Figure 6 As shown, the measuring component 400 of the embodiment of the present application further includes two blocks 450 ; the two blocks 450 are symmetrically arranged on both sides of the shell 410 and fixed to the shell 410 , and the two blocks 450 are both in contact with the load-bearing block 440 to limit the position of the load-bearing block 440 .

[0082] In a specific implementation, two blocks 450 are provided on opposite sides of the housing 410. The blocks 450 are fixedly connected to the housing 410 and abut against the two ends of the bearing groove 441. Thus, while not affecting the bearing groove 441 from being hit by the door panel, it can prevent the bearing block 440 from directly popping out of the housing 410 and the force measuring screw 432 when it rebounds after being hit, effectively limiting the position of the bearing block 440 and ensuring the use effect of the closing force test device. The block 450 can be made of a material with a relatively low hardness to avoid damaging the bearing block 440 when colliding with the bearing block 440. The specific material is not limited in this application, and it only needs to be able to effectively limit the position of the bearing block 440.

[0083] In some possible implementations, see Figure 2 , Figure 6 and Fig. 9As shown, the stopper 450 of the embodiment of the present application has a connecting portion 451 and a limiting portion 452, the connecting portion 451 and the limiting portion 452 are perpendicular to each other, the connecting portion 451 is fixedly connected to the side wall of the shell 410, and the two ends of the limiting portion 452 are respectively abutted against the side wall of the shell 410 and the load-bearing block 440.

[0084] Specifically, the end of the stopper 452 of the stopper 450 that abuts against the bearing block 440 can be set as an inclined surface, and the inclined surface is smoothly connected to the inner wall of the bearing groove 441, so as to reserve enough space for the door panel to hit the bearing groove 441. The connecting portion 451 and the limiting portion 452 are perpendicular to each other, which can ensure the stability of the connection between the stopper 450 and the housing 410. The connecting portion 451 and the housing 410 can be connected by bolts 310 so that they can be disassembled for replacement or maintenance at any time. The specific connection method is not limited in this application, and it only needs to be able to be stably connected to the housing 410.

[0085] In some possible implementations, see Figure 2 , Figure 6 and Figure 8 As shown, the shell 410 of the embodiment of the present application has a side where a stopper 450 is provided, and an escape opening 411 is opened. Two stoppers 450 are respectively located on two opposite sides of the escape opening 411 , and part of the load-bearing block 440 is located above the escape opening 411 .

[0086] In the specific implementation, it is necessary to set an avoidance opening 411 on the shell 410. The width of the avoidance opening 411 can be set to be slightly larger than the width of the door panel. This can prevent the door panel from contacting the shell 410 when hitting the load-bearing block 440, thereby dispersing part of the closing force on the shell 410 and affecting the accuracy of the measurement.

[0087] In some possible implementations, see Figure 1 , Figure 2 and Figure 3 As shown, the locking assembly 300 of the embodiment of the present application includes a bolt 310 and a nut 320 . The bolt 310 passes through the first adjustment portion 120 and the second adjustment portion 220 in sequence and is connected to the nut 320 to lock the movable seat 200 and the fixed seat 100 .

[0088] In some embodiments, the locking assembly 300 can be a bolt 310 and a nut 320. The bolt 310 passes through the arc-shaped through hole 121 and the eccentric hole 221 and is connected to the nut 320. After adjusting the angle between the movable seat 200 and the fixed seat 100, tightening the nut 320 can keep the two at the current angle. When adjusting the angle, it is only necessary to slightly loosen the nut 320 so that the movable seat 200 can rotate and move relative to the fixed seat 100 with the bolt 310 as the axis. It is easy to operate and has strong stability.

[0089] In summary, the closing force test device provided by the present application includes a fixed seat 100, a movable seat 200, a locking assembly 300 and a measuring assembly 400.
