[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0025] In this disclosure, unless otherwise stated, directional terms such as "first direction," "second direction," and "third direction" refer to the directions indicated by L1, L2, and L3 in the accompanying drawings, respectively. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not imply sequentiality or importance. Additionally, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.
[0026] According to a specific embodiment of this disclosure, a seatbelt buckle testing device is provided, with reference to... Figure 1 , Figure 3 and Figure 4 As shown, the seatbelt buckle includes a buckle 31 and a socket 32. The testing device includes: an unlocking member 1; a driving mechanism, which includes a first driving member 21 and a second driving member 22, wherein the first driving member 21 is used to drive the buckle 31 to move relative to the socket 32 in a first direction to insert into the socket 32, and the second driving member 22 is used to drive the unlocking member 1 to move relative to the socket 32 in the first direction to abut against the socket 32 so that the buckle 31 is separated from or moved away from the socket 32; and an adjustment mechanism, which is used to adjust the angle between one or both of the buckle 31 and the socket 32 and the horizontal reference plane and / or the vertical reference plane.
[0027] Through the above technical solution, in the seat belt buckle testing device provided in this disclosure, the adjustment mechanism adjusts the angle between the buckle ring 31 and / or the socket 32 relative to the horizontal reference plane and / or the vertical reference plane. This allows the buckle ring 31 and / or the socket 32 to remain parallel to the horizontal reference plane or to have any angle there. Similarly, the buckle ring 31 and / or the socket 32 can also remain parallel to the vertical reference plane or to have any angle there. This allows adjustment of the orientation of the buckle ring 31 and / or the socket 32 in three-dimensional space, ensuring that the buckle ring 31 and the socket 32 remain parallel or have an angle. This simulates various working conditions of the seat belt buckle during use (such as the buckle ring 31 and the socket 32 being perfectly aligned or having an angle), enabling multiple insertions and separations of the buckle ring 31 and the socket 32 under different working conditions via the first driving member 21 and the second driving member 22. In summary, this testing device can test seat belt buckles and helps improve the accuracy of test results.
[0028] In the testing apparatus provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 1 and Figure 2 As shown, the testing device may further include a base frame 51, and the adjustment mechanism may include at least two first adjustment structures 41 and at least two second adjustment structures 42. Both the first and second adjustment structures 41 and 42 may be spaced apart along a second direction. The first adjustment structures 41 may be used to adjust the position of the retaining ring 31 and / or socket 32 relative to the base frame 51 along a third direction, and the second adjustment structures 42 may be used to adjust the position of the retaining ring 31 and / or socket 32 relative to the base frame 51 along a first direction. The two first adjustment structures 41 may be respectively disposed on opposite sides of the retaining ring 31 and / or socket 32 along the second direction. Thus, when the position of the retaining ring 31 and / or socket 32 relative to the base frame 51 is adjusted by one of the first adjustment structures 41 along a third direction, one side of the retaining ring 31 and / or socket 32 along the second direction may be tilted relative to the horizontal reference plane to adjust the angle between the retaining ring 31 and / or socket 32 and the horizontal reference plane. Similarly, the two second adjustment structures 42 can be respectively set on opposite sides of the buckle 31 and / or socket 32 along the second direction. In this way, when the position of the buckle 31 and / or socket 32 relative to the base frame 51 is adjusted by one of the second adjustment structures 42 along the first direction, the buckle 31 and / or socket 32 can be tilted up on one side along the second direction relative to the vertical reference plane to adjust the included angle between the buckle 31 and / or socket 32 and the vertical reference plane.
[0029] Furthermore, it should be noted that "the first adjustment structure 41 can be used to adjust the position of the buckle 31 and / or the socket 32 relative to the base frame 51 in a third direction, and the second adjustment structure 42 can be used to adjust the position of the buckle 31 and / or the socket 32 relative to the base frame 51 in a first direction" includes at least the following four implementation methods.
[0030] Implementation Method 1: The first adjustment structure 41 can be used to adjust the position of the retaining ring 31 relative to the base frame 51 along a third direction, and the second adjustment structure 42 can be used to adjust the position of the retaining ring 31 relative to the base frame 51 along a first direction. That is, the first adjustment structure 41 and the second adjustment structure 42 can be provided simultaneously between the retaining ring 31 and the base frame 51. In this implementation method, the socket 32 can be directly installed on the base frame 51. In this way, the orientation of the retaining ring 31 in three-dimensional space can be adjusted by adjusting the angle between the retaining ring 31 and the horizontal reference plane and the vertical reference plane, so that the retaining ring 31 and the socket 32 remain parallel or have an angle.
[0031] Implementation Method Two: The first adjustment structure 41 can be used to adjust the position of the socket 32 relative to the base frame 51 along a third direction, and the second adjustment structure 42 can be used to adjust the position of the socket 32 relative to the base frame 51 along a first direction. That is, the first adjustment structure 41 and the second adjustment structure 42 can be provided simultaneously between the socket 32 and the base frame 51. In this implementation method, the retaining ring 31 can be directly installed on the base frame 51. In this way, the orientation of the socket 32 in three-dimensional space can be adjusted by adjusting the angle between the socket 32 and the horizontal reference plane and the vertical reference plane, so that the retaining ring 31 and the socket 32 remain parallel or have an angle.
[0032] Implementation Method 3: The first adjustment structure 41 can be used to adjust the position of the socket 32 relative to the base frame 51 along a third direction, and the second adjustment structure 42 can be used to adjust the position of the retaining ring 31 relative to the base frame 51 along a first direction. That is, the first adjustment structure 41 can be provided between the socket 32 and the base frame 51, and the second adjustment structure 42 can be provided between the retaining ring 31 and the base frame 51. In this way, by adjusting the angle between the socket 32 and the horizontal reference plane, and the angle between the retaining ring 31 and the vertical reference plane, the retaining ring 31 and the socket 32 can be kept parallel or have an angle. In addition, the retaining ring 31 can be accurately adjusted by adjusting only through the second adjustment structure 42, and the socket 32 can be accurately adjusted by adjusting only through the first adjustment structure 41, and the angle between the socket 32 and the horizontal reference plane can be accurately adjusted.
[0033] Implementation Method 4: The first adjustment structure 41 can be used to adjust the position of the retaining ring 31 relative to the base frame 51 along a third direction, and the second adjustment structure 42 can be used to adjust the position of the socket 32 relative to the base frame 51 along a first direction. That is, the first adjustment structure 41 can be provided between the retaining ring 31 and the base frame 51, and the second adjustment structure 42 can be provided between the socket 32 and the base frame 51. In this way, by adjusting the angle between the retaining ring 31 and the horizontal reference plane, and the angle between the socket 32 and the vertical reference plane, the retaining ring 31 and the socket 32 can be kept parallel or have an angle. In addition, the retaining ring 31 can be accurately adjusted by adjusting only through the first adjustment structure 41, and the socket 32 can be accurately adjusted by adjusting only through the second adjustment structure 42, and the angle between the socket 32 and the vertical reference plane can be accurately adjusted.
[0034] To simplify the description, the following explanation will only use the fourth embodiment described above as an example.
[0035] In the testing apparatus provided in this disclosure, the first adjustment structure 41 and the second adjustment structure 42 can be constructed in any suitable manner. As an exemplary embodiment, refer to... Figures 1 to 4 As shown, a first mounting base 52 and a second mounting base 53 can be mounted on the base frame 51. The first adjustment structure 41 may include a first fastener 44 and a first elastic element 45. The first fastener 44 can have a retaining ring 31 inserted along a third direction and be fastened to the first mounting base 52. The first elastic element 45 can be sleeved on the first fastener 44 and arranged between the retaining ring 31 and the first mounting base 52. The first fastener 44 can be constructed as a bolt, and a bolt can be provided on each side of the retaining ring 31 along the second direction. In this way, by rotating one of the bolts, the retaining ring 31 can move closer to or away from the first mounting base 52 along one side of the second direction. Therefore, the angle between the retaining ring 31 and the horizontal reference plane can be adjusted by controlling the degree of screwing in the bolts, which is beneficial for fine adjustment of the angle between the retaining ring 31 and the horizontal reference plane, and also for fine-tuning the angle between the retaining ring 31 and the horizontal reference plane. In addition, the first elastic element 45 can be constructed as a compression spring, so that the two ends of the first elastic element 45 can abut against the retaining ring 31 and the first mounting base 52 respectively, so that the retaining ring 31 can be pressed between the first elastic element 45 and the head of the bolt. In this way, after each adjustment of the orientation of the retaining ring 31, the above design can keep the retaining ring 31 in the current orientation, which is beneficial to the accuracy of the test results.
[0036] A socket 32 can be installed on the second mounting base 53. The second adjustment structure 42 may include a second fastener 46 and a second elastic member 47. The second fastener 46 can pass through the base frame 51 along the first direction and be securely installed on the second mounting base 53. The second elastic member 47 can be sleeved on the second fastener 46 and arranged between the base frame 51 and the second mounting base 53. The second fastener 46 can be constructed as a bolt, and the second mounting base 53 can have a bolt on each of its two sides along the second direction. This allows one bolt to be rotated to move the socket 32 closer to or away from the base frame 51 along one side of the second direction via the second mounting base 53. Therefore, the angle between the socket 32 and the vertical reference plane can be adjusted by controlling the degree of screwing in the bolt, which is beneficial for fine-tuning the angle between the socket 32 and the vertical reference plane, and also for micro-adjusting the angle between the socket 32 and the vertical reference plane. In addition, the second elastic element 47 can be constructed as a compression spring, so that the two ends of the second elastic element 47 can respectively abut against the base 51 and the second mounting base 53. After each adjustment of the orientation of the socket 32, the second elastic element 47 can keep the second mounting base 53 in the current position, thereby keeping the socket 32 in the current orientation, which is beneficial to the accuracy of the test results.
[0037] In the testing apparatus provided in this disclosure, the mounting between the base frame 51 and the first mounting base 52 can be achieved in any suitable manner. As an exemplary embodiment, refer to... Figure 3 and Figure 4 As shown, the first mounting base 52 can be slidably mounted on the base frame 51. One of the base frame 51 and the first mounting base 52 can be provided with a slide rail, and the other with a slide groove. The slide rail can be arranged along a first direction, ensuring that the first mounting base 52 slides relative to the base frame 51 along the first direction, thereby ensuring that the retaining ring 31 slides relative to the base frame 51 along the first direction. This avoids interference with the accuracy of test results due to wobbling between the base frame 51 and the first mounting base 52. Furthermore, the design of the slide rail and slide groove allows the first mounting base 52 to be directly mounted on the base frame 51, thereby improving the stability and durability of the first mounting base 52.
[0038] In the testing apparatus provided in this disclosure, the installation between the socket 32 and the second mounting base 53 can be achieved in any suitable manner. As an exemplary embodiment, reference is made to... Figure 1 , Figure 2 and Figure 4As shown, the testing device may further include a third fastener 54. The second mounting base 53 may include a first block 531 and a second block 532 arranged opposite to each other. The third fastener 54 may pass through the first block 531 and be fastened to the second block 532, so as to press the socket 32 onto the second block 532 through the first block 531. The socket 32 may be arranged between the first block 531 and the second block 532. The third fastener 54 may be constructed as a bolt. In this way, by continuously tightening the bolt, the first block 531 and the second block 532 can be pressed against the opposite sides of the socket 32, that is, there will be friction between the first block 531 and the socket 32, and between the second block 532 and the socket 32. This friction can keep the socket 32 and the second mounting base 53 moving synchronously.
[0039] In the testing apparatus provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 1 , Figure 2 and Figure 4 As shown, the testing device may further include a base frame 51, and the adjustment mechanism may further include an adjustment rod 43. The adjustment rod 43 may have a first end and a second end arranged opposite to each other. The first end may be fixed to the socket 32, and the second end may be rotatably mounted on the base frame 51 about a vertical axis. The second end may be mounted on the base frame 51 via a pin extending in a third direction. Thus, when the adjustment rod 43 rotates about the vertical axis (i.e., the axis of the pin), the socket 32 fixed to the first end can rotate about the vertical axis on a horizontal reference plane to adjust the position of the socket 32 relative to the base frame 51 or the second mounting base 53.
[0040] In the testing apparatus provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 3As shown, the testing device may further include a base frame 51, a third elastic element 61, and a fourth elastic element 62. A first driving element 21 may be mounted on the base frame 51. The output end of the first driving element 21 can abut against the first mounting base 52 via the third elastic element 61. The third elastic element 61 may be configured to provide pressure that moves the first mounting base 52 closer to the socket 32 when it abuts against the first mounting base 52. A fourth elastic element 62 may be provided between the base frame 51 and the first mounting base 52. The fourth elastic element 62 may be configured to provide a pulling force that moves the first mounting base 52 away from the socket 32 when the retaining ring 31 separates from the socket 32. The first driving element 21 may be configured as a cylinder. In other embodiments, the first driving element 21 may also be selected from other linear motion mechanisms; this disclosure does not impose specific limitations on this. Thus, when the output end of the first driving element 21 moves toward the socket 32, the third elastic element 61 abuts against the first mounting base 52 and pushes the first mounting base 52 to also move toward the socket 32 until the retaining ring 31 on the first mounting base 52 is inserted into the socket 32. During this process, the third elastic element 61 reduces the impact force between the first driving element 21 and the first mounting base 52, preventing damage to the first driving element 21 or the first mounting base 52. Similarly, it also reduces the impact force between the retaining ring 31 and the socket 32, preventing damage to the retaining ring 31 or the socket 32. Furthermore, after the retaining ring 31 separates from the socket 32, the fourth elastic element 62 can pull the retaining ring 31 away from the socket 32. The fourth elastic element 62 can be constructed as a rubber band, which facilitates replacement of the fourth elastic element 62, and the pulling force of the fourth elastic element 62 on the retaining ring 31 can be adjusted by controlling the number of rubber bands.
[0041] In the testing apparatus provided in this disclosure, the testing apparatus may further include a base frame 51, a connecting plate 71, and a fifth elastic member 72. The unlocking member 1 can be connected to the output end of the second driving member 22 through the connecting plate 71. The unlocking member 1 can be constructed as an unlocking rod, which may have a third end and a fourth end arranged opposite to each other. The third end can slide through the connecting plate, and the fourth end may be provided with an unlocking block protruding along the axial direction of the unlocking rod. A fifth elastic member 72 may be provided between the unlocking block and the connecting plate 71. The fifth elastic member 72 may be constructed to undergo elastic deformation when the unlocking block contacts the socket 32. The second driving member 22 may be constructed as a cylinder. In other embodiments, the second driving member 22 may also be selected from other linear motion mechanisms, and this disclosure does not impose specific limitations on this. Thus, when the output end of the second driving member 22 moves toward the socket 32, the unlocking member 1 also moves synchronously until the unlocking block presses against the socket 32. Afterward, the output end of the second driving member 22 continues to move toward the socket 32, forcing the fifth elastic member 72 to compress. The elastic force of the fifth elastic member 72 then presses the unlocking member 1 firmly against the socket 32, thereby separating the socket 32 from the retaining ring 31. During this process, the fifth elastic member 72 reduces the impact force between the unlocking member 1 and the second mounting base 53, preventing damage to the unlocking member 1 or the second mounting base 53. Similarly, it also reduces the impact force between the unlocking member 1 and the output end of the second driving member 22, preventing damage to the unlocking member 1 or the second driving member 22. Furthermore, the connecting plate 71 facilitates the sliding of the unlocking member 1 relative to the output end of the second driving member 22.
[0042] In the testing apparatus provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 3 and Figure 4 As shown, an elastic support 73 can be provided between the connecting plate 71 and the output end of the second driving member 22. The elastic support 73 can be configured to elastically deform when the force between the unlocking member 1 and the socket 32 exceeds a preset pressure. The smaller of the maximum pressure that the unlocking member 1 can withstand or the maximum pressure that the socket 32 can withstand can be designated as the ultimate pressure. Both the preset pressure and the maximum elastic force of the elastic support 73 are less than the ultimate pressure. Thus, when the force between the unlocking member 1 and the socket 32 exceeds the preset pressure, the elastic support 73 can elastically deform to prevent excessive thrust at the output end of the second driving member 22 from damaging the unlocking member 1 or the socket 32. Those skilled in the art can set a suitable preset pressure according to actual needs; this disclosure does not specifically limit this setting.
[0043] In the testing apparatus provided in this disclosure, the testing apparatus may further include an indicator light 84, and a normally closed switch 85 is provided in the socket 32. The indicator light 84 is configured to turn off when the retaining ring 31 is inserted into the socket 32 to open the normally closed switch 85. In this way, the current working status of the testing apparatus can be intuitively observed by the on and off state of the indicator light 84. In addition, when the testing apparatus malfunctions, the indicator light 84 may be in a constantly on or constantly off state, so that the staff can promptly detect problems and repair the testing apparatus by using the indicator light 84.

In addition, when the testing apparatus malfunctions, the indicator light 84 may be in a constantly on or constantly off state. In this way, the staff can promptly detect the fault and repair the testing apparatus by observing the indicator light 84, which helps to ensure the reliability of the testing apparatus.
[0045] In addition, the testing device also includes a control module 81. The first drive member 21 and the second drive member 22 are both electrically connected to the control module 81. The control module 81 can measure the number of reversing valves in the first drive member 21 and / or the second drive member 22, thereby measuring the number of reciprocating cycles at the output end of the first drive member 21 and / or the second drive member 22 (that is, the number of times the retaining ring 31 is inserted into the socket 32).
[0046] In addition, the testing device also includes an on / off switch 86, an on / off switch 87, a reset switch 88, and a display screen 89. The on / off switch 86, the on / off switch 87, the reset switch 88, and the display screen 89 are all mounted on the base frame 51 via the control box 82 and are all electrically connected to the control module 81. In this way, information such as the number of times the buckle 31 and the socket 32 are plugged in can be observed intuitively through the display screen 89. The testing device can also be directly operated through the on / off switch 86, the on / off switch 87, and the reset switch 88, making operation convenient.
[0047] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings.
