Therefore, strict testing of scissor door struts is an important link to ensure their performance meets the standards. As an indispensable equipment in the testing process, the design and use of the test bench have an important impact on the accuracy and reliability of the test results. Existing scissor door strut testing devices usually fix the door panel on the detection table, and then apply pushing and pulling forces to the door panel through the activation of the strut and feedback, so as to collect strut data.

The conventional fixed detection method cannot feedback comprehensive data on the operation of the strut, and lacks measurement equipment that can sense and measure the tilt angle, tilt direction, and the force change of the strut during tilting, resulting in single data and reducing the detection accuracy.

[0034] The following will further elaborate on this application in conjunction with the accompanying Figure 1 - Figure 5 drawings.

[0035] An embodiment of this application discloses a test bench for a scissor door strut.

[0036] Referring to Figure 1 、 Figure 2 、 Figure 4 , a test bench for a scissor door strut includes a main frame 1. The main frame 1 is integrally formed by fixing multiple connecting columns and is a hollow rectangle inside. At the same time, grooves are provided on the surface of each connecting column for easy screw connection. A support beam 8 is fixed by screws on one side inside the frame of the main frame 1. On one side adjacent to the support beam 8 inside the bottom frame of the main frame 1, an installation groove 5 is opened inward, and a rectangular simulated door frame 2 is movably inserted into the installation groove 5. Cross beams for support are fixed at both ends in the middle of the simulated door frame 2. A counterweight 9 is screwed to the side surface of the cross beam, and the counterweight 9 can be removably installed.

[0037] The interior of the main frame 1 is hollow to facilitate the subsequent installation of the opening and closing mechanism 3. At the same time, the support beam 8 is fixed on one side of the main frame 1, providing an installation fulcrum for the opening and closing mechanism 3 and strengthening the overall stability of the main frame 1. The installation groove 5 is inserted with the simulated door frame 2 to limit the simulated door frame 2 and form a horizontal fixation. And the simulated door frame 2 can maintain longitudinal movement during the opening and closing test, and the weight of the simulated door frame 2 can be adjusted by adding the counterweight 9 to simulate the weights of different door shapes.

[0038] Referring to Figure 1 、 Figure 4 , the opening and closing mechanism 3 includes a lock installation bracket 38 screwed to the surface of the simulated door frame 2 close to the support beam 8. And on both sides of the inner wall of the lock installation bracket 38, a lock body 39 that can rotate and be locked is movably connected. One side of the lock body 39 close to the simulated door frame 2 penetrates the side surface of the lock installation bracket 38 and is fixedly connected with a connecting plate 37. The connecting plate 37 is L-shaped, and the end of the connecting plate 37 away from the lock body 39 is fixed to the simulated door frame 2 by screws. On the surface of the other end of the simulated door frame 2 away from the connecting plate 37, a second mounting plate 33 is screwed and fixed. A mounting hinge 32 is rotatably connected to the other side surface of the second mounting plate 33 relative to the simulated door frame 2. The other end of the mounting hinge 32 relative to the second mounting plate 33 is rotatably connected to a first mounting plate 31. The side surface of the first mounting plate 31 away from the mounting hinge 32 is fixed to the main frame 1 by screws.

[0039] It should be noted that one end of the side surface of the mounting hinge 32 is rotatably connected to a gas strut 34. The bottom of the gas strut 34 is rotatably connected to a fixing plate 36. On one side of the gas strut 34 on the side surface of the mounting hinge 32, an electric strut 35 is rotatably connected. The bottom of the electric strut 35 is also rotatably connected to the upper end surface of the fixing plate 36. And pipelines are connected in both the gas strut 34 and the electric strut 35 for connecting external electrical supply equipment. The bottom of the fixing plate 36 is fixed to the main frame 1 by screws.

[0040] The telescopic ends of the gas strut 34 and the electric strut 35 extend to jack up the mounting hinge 32. The mounting hinge 32 is subjected to a thrust force, which drives the second mounting plate 33 to be jacked up synchronously, causing the right end side of the simulated door frame 2 to be jacked up. At the same time, the left end of the simulated door frame 2 is connected to the connecting plate 37 to form an overall connection with the lock body 39, providing a fulcrum for the left end of the simulated door frame 2. And the lock body 39 rotates with the connecting plate 37. When the right end of the simulated door frame 2 is subjected to the jacking of the gas strut 34 and the electric strut 35, the right end of the simulated door frame 2 rotates upward with the lock body 39 as the fulcrum, and the bending angle of the mounting hinge 32 can be adjusted, thereby increasing the included angle between the simulated door frame 2 and the first mounting plate 31, and the strut force received by the simulated door frame at different angles.

[0041] Refer to Figure 1 、 Figure 3 、 Figure 5 As shown in FIGS.

[0042] It should be noted that a latch for fixing the pulley 41 is fixed on the side surface of the pulley 41. Normally, the screw rod 44 is located inside the frame body of the main frame 1, so that the connection point between the pulley 41 and the screw rod 44 abuts against the bottom surface of the adjusting plate 42. At the same time, a door stop bracket 6 is fixed inside the frame body of the main frame 1 between two of the adjusting plates 42. One end of the upper end surface of the door stop bracket 6 close to the simulated door frame 2 is fixed with a door stopper 7. And normally, the top of the door stopper 7 abuts against the side surface of the simulated door frame 2.

[0043] The four screw rods 44 are respectively rotated downward from the nuts 43, thereby respectively increasing the distance between the four pulleys 41 and the adjusting plate 42. Cooperating with the overall fixation of the adjusting plate 42 and the main frame 1, multiple points at the bottom of the main frame 1 are raised, thereby changing the overall inclination angle of the main frame 1. At the same time, the door stopper 7 is integrally fixed in the main frame 1 through the door stop bracket 6, thereby increasing the resistance received when the simulated door frame 2 moves, which is convenient for safety testing.

[0044] Among them, the installation hinge 32, gas strut 34, electric strut 35, lock body 39 and door stopper 7 of this device are all prior arts, and their structural principles will not be elaborated herein.

[0045] The implementation principle of a scissors door strut test bench in an embodiment of this application is as follows: When using this device, personnel rotate the four screws 44 respectively, and turn the screws 44 out downward from the nuts 43, so as to extend the distance between the pulley 41 and the adjustment plate 42, making the main frame 1 as a whole in an inclined state, and fixing the latch on one side of the pulley 41 to make the pulley 41 in a fixed state;

[0046] Then, the personnel control the microcomputer to send signals to control the telescopic rods of the gas strut 34 and the electric strut 35 to extend respectively. The telescopic rods of the gas strut 34 and the electric strut 35 respectively push the installation hinge 32 to move upward, thereby driving the second installation plate 33 to move synchronously, making the right side of the simulated door frame 2 move upward. At the same time, the left side of the simulated door frame 2 is connected to the lock body 39 and then fixed to the main frame 1, so as to form the right side of the simulated door frame 2 rotating around the connection point of the lock body 39. At this time, the personnel collect the supporting force data of the gas strut 34 and the electric strut 35 according to the inclination angle of the simulated door frame 2;

[0047] At the same time, the personnel can release the latch of the pulley 41 to make the pulley 41 in a movable state, thereby pushing the main frame 1 as a whole, so as to collect the data feedback by different struts when the vehicle moves on slopes, making the data more comprehensive and improving the detection accuracy.

[0048] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape and principle of this application shall be covered within the protection scope of this application.
