Description

Technical Field

[0001] This utility model relates to the technical field of seat belts, and in particular to a seat belt buckle insertion / removal testing device. Background Technology

[0002] As a core component of a vehicle's passive safety system, the seatbelt buckle plays a crucial role in ensuring occupant safety during a collision. According to the current national standard GB14166-2013, seatbelt buckles must withstand sufficient cycles of insertion and removal durability testing to verify their reliability and stability in long-term use.

[0003] Manual testing relies on operators manually inserting and removing buckles, which is inefficient. While existing automated testing equipment has improved efficiency to some extent, it still faces some technical bottlenecks. For example, it can only perform simple insertion and removal processes and cannot test the insertion and connection strength between the buckle and the buckle holder, resulting in limited testing functionality.

Detailed Implementation

[0038] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] like Figures 1 to 5 As shown, this embodiment provides a seatbelt buckle insertion / removal testing device, including:

[0041] Mounting base 1 is the basic fixed structure of the entire testing device. It is independently fixed and is equipped with a fixing mechanism 2 and a moving mechanism 3. The fixing mechanism 2 is used to fix the buckle seat, and the moving mechanism 3 is used to fix the buckle.

[0042] Guide component 4 is installed on mounting base 1, and assembly 5 is slidably installed on mounting base 1 via guide component 4. Guide beam 6 is provided in the inner groove of assembly 5, and moving mechanism 3 is slidably installed on guide beam 6.

[0043] Adjustment mechanism 7 is installed on assembly 5, and spring 8 is provided on adjustment mechanism 7. The other end of spring 8 is installed on moving mechanism 3. Adjustment mechanism 7 is used to adjust the compression strength of spring 8.

[0044] The buffer pad 9 is installed in the inner groove of the assembly 5. The buffer pad 9 is used to absorb shock after the spring 8 drives the moving mechanism 3 to move.

[0045] The drive mechanism 10 is installed inside the cavity on the mounting base 1 and is used to provide reciprocating swing power to the assembly 5.

[0046] In this embodiment, the mounting base 1 serves as the basic fixed structure, on which the fixing mechanism 2 and the moving mechanism 3 respectively fix the buckle seat and the buckle, providing a stable mounting base for testing. The guide member 4 limits the movement trajectory of the assembly 5, ensuring the straightness of the buckle insertion and removal trajectory and avoiding test errors caused by shaking. The guide beam 6 is used to control the relative movement trajectory between the moving mechanism 3 and the assembly 5. The adjusting mechanism 7 adjusts the compression strength of the spring 8 to control the buckle and buckle seat to disengage when the drive mechanism 10 drives the assembly 5 to reset. The buffer pad 9 is used to absorb shock after the buckle and buckle seat are disengaged by the moving mechanism 3 driven by the spring 8, reducing hard collision damage to the assembly 5 and extending the service life of the equipment. The drive mechanism 10 is installed in the cavity of the mounting base 1 to provide reciprocating swing power, realize automated cyclic testing, improve testing efficiency, and ensure the consistency of each insertion and removal action through programmed control, ensuring the quality and reliability of the core components of the automotive passive safety system.

[0047] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the adjustment mechanism 7 includes:

[0048] The threaded post 71 is fitted into the threaded through hole of the assembly 5, and an adjusting cap 72 is provided on the threaded post 71;

[0049] The transmission component 73 is slidably mounted on the guide beam 6, the threaded column 71 is rotatably connected to the transmission component 73, and the spring 8 is mounted on the transmission component 73;

[0050] A nut 74 is installed on the threaded post 71, and the nut 74 is used to lock the connection position between the threaded post 71 and the assembly 5.

[0051] In this embodiment, the threaded post 71 engages with the threaded through hole of the assembly 5. Utilizing the high precision characteristics of threaded transmission, rotating the adjusting cap 72 drives the threaded post 71 to move axially. Through rotational connection with the transmission component 73, the rotational motion of the threaded post 71 is converted into linear sliding of the transmission component 73 along the guide beam 6, precisely adjusting the compression degree of the spring 8. This controls the traction strength when the buckle disengages from the buckle seat. The transmission component 73 is slidably mounted on the guide beam 6 to ensure stable movement trajectory, uniform force on the spring 8, and consistent adjustment effect. The nut 74 locks the connection position between the threaded post 71 and the assembly 5, preventing the threaded post 71 from loosening due to vibration during testing. This ensures the stability of the spring 8 compression strength setting value, avoids affecting the accuracy of test results due to changes in the spring 8 compression strength, and improves the versatility of the testing device and the reliability of test data.

[0052] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the moving mechanism 3 includes:

[0053] The movable seat 31 is slidably installed in the inner groove of the assembly 5 via the guide beam 6. The movable seat 31 is provided with a positioning pin 32 for positioning and placing the buckle.

[0054] Bolt 33 engages with the threaded inner hole of locating pin 32 to fix the position of the buckle;

[0055] The ejection mechanism 34 is mounted on the movable base 31 and is used to control the disengagement of the buckle from the buckle seat.

[0056] Return agency 34 includes:

[0057] Cylinder 34a is mounted on movable seat 31. Cylinder 34a is used to press the control buckle of buckle seat when buckle is disengaged from buckle seat.

[0058] Protective pad 34b is installed at the output end of cylinder 34a;

[0059] In this embodiment, the movable seat 31 is slidably installed in the inner groove of the assembly 5 via the guide beam 6, ensuring that the buckle moves along a precise trajectory during the test and avoiding test errors caused by shaking. The positioning pin 32 on the movable seat 31 cooperates with the bolt 33 to achieve rapid positioning and firm fixation of the buckle, ensuring the stability of the buckle installation during the test and facilitating the replacement of buckles of different specifications, thus improving test efficiency. The cylinder 34a in the part removal mechanism 34 can automatically squeeze the buckle seat control buckle to achieve the disengagement control of the buckle from the buckle seat, ensuring that the force of each disengagement action is uniform and the timing is accurate. The protective pad 34b at the output end of the cylinder 34a can prevent hard damage to the buckle seat control buckle during the squeezing process, thus protecting the integrity of the test component and avoiding test data deviation caused by component damage, greatly improving the efficiency, accuracy and reliability of seat belt buckle insertion and removal tests.

[0060] As a preferred embodiment of the above technical solution, such as Figures 3 to 4 As shown, the drive mechanism 10 includes:

[0061] The fastener 101 is installed on the assembly 5 and passes through the through groove of the mounting base 1;

[0062] The conductive element 102 is mounted on the fixing element 101, and the conductive element 102 is provided with a guide groove.

[0063] A support beam 103 is installed in the cavity of the mounting base 1. A crankshaft 104 is rotatably mounted on the support beam 103. The crankshaft 104 is slidably connected to the guide groove of the transmission component 102.

[0064] The drive motor 105 is installed inside the cavity of the mounting base 1, and the output end of the drive motor 105 is coaxially mounted with the crankshaft 104.

[0065] The guide groove consists of a straight groove and a circular arc groove, and the radius of the circular arc groove is the same as the eccentric radius of the crankshaft 104. The crankshaft 104 slides with the straight groove to drive the buckle to move. The crankshaft 104 slides with the circular arc groove to allow the buckle to move intermittently. At this time, it is used to detect the connection strength between the buckle and the buckle seat and to provide a time difference for the engagement and disengagement.

[0066] In this embodiment, the fixing member 101 is connected to the assembly 5 and passes through the through groove of the mounting base 1, providing a stable connection for the reciprocating motion of the assembly 5. The unique combination of straight groove and arc groove on the transmission member 102 guides the crankshaft 104 to achieve precise switching of motion trajectory. The drive motor 105 drives the crankshaft 104 to rotate. When the crankshaft 104 slides along the straight groove, it can stably drive the assembly 5 and the buckle to perform linear displacement, completing the insertion and removal action of the buckle and the buckle seat, ensuring the consistency and accuracy of each insertion and removal action. When the crankshaft 104 slides into the arc groove, the characteristic that the radius of the arc groove is the same as the eccentric radius of the crankshaft 104 is used to achieve the relative stillness of the assembly at this time, and precisely control the timing of the cylinder 34a pressing the buckle seat to control the buckle, making the buckle and buckle seat disengagement process more stable and efficient. At the same time, it provides a test time difference for testing the connection strength between the buckle and the buckle seat, reducing manual intervention and improving the reliability of test data and the standardization of the test process.

[0067] As a preferred embodiment of the above technical solution, such as Figures 1 to 3 As shown, the fixing mechanism 2 includes:

[0068] The fixing base 21 is installed on the mounting base 1. The fixing base 21 is provided with a positioning groove for positioning and placing the buckle seat.

[0069] Screw 22 engages with the threaded slot of the fixing seat 21 for a fixed connection between the snap fastener and the fixing seat 21.

[0070] In this embodiment, the fixing seat 21 is installed on the mounting base 1. The positioning groove on it can accurately position the buckle seat, ensuring that the buckle seat is in the standard position during the test and avoiding errors in the test results due to installation deviation. The screw 22 is connected to the threaded slot of the fixing seat 21, which can firmly fix the buckle seat to the fixing seat 21. When the drive mechanism 10 drives the moving mechanism 3 to perform high-frequency insertion and removal tests, it can effectively prevent the buckle seat from loosening or shifting, and ensure the stability of the test process.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
