DETAILED DESCRIPTION

[0032] Example 1: Reference Figures 1-8, a vehicle door hinge bearing force detection auxiliary device, comprising a base 1, a mounting bracket 2 is fixed to the outer wall of one end of the base 1, the mounting bracket 2 is used to fix the female hinge of the hinge body 4, a horizontally placed turntable 5 is rotatably provided on the base 1, and a fixing component 6 is installed on the turntable 5, and the fixing component 6 is used to be fixed with the male hinge of the hinge body 4. It should be noted that: the vehicle door hinge is generally divided into a female hinge and a male hinge that are arranged to rotate with each other, and the female hinge is the part fixed to the vehicle body, and the male hinge is fixed to the vehicle door; a driving component 7 is also provided on the mounting bracket 2; a horizontally extending push rod 11 is provided in the fixing component 6, and the push rod 11 extends horizontally from the fixing component 6 in a direction away from the hinge body 4, and the driving component 7 is provided with two arc-shaped electric guide rails 8 fixed to the mounting bracket 2, and a connecting bracket 9 is connected to the lower part of the arc-shaped electric guide rail 8, and the two connecting brackets 9 are located on both sides of the push rod 11. A striker 10 is installed on the connecting bracket 9 toward the position of the push rod 11, and the striker 10 is horizontally moved near one end of the connecting bracket 9 The cam 10 is extended and a pressure sensor is connected between the cam 10 and the connecting frame 9. The cam 10 is vertically extended away from the connecting frame 9. The turntable 5, the arc-shaped electric guide rail 8 and the hinge body 4 are set to the same rotation axis. It should be noted that after the female hinge of the hinge body 4 is fixed on the mounting frame 2, the rotating shaft between the female hinge and the male hinge extends vertically upward, and the rotating shaft is exactly arranged in the same direction as the axis of the turntable 5 and the arc-shaped electric guide rail 8; when in use, the female hinge of the hinge body 4 is fixed to the mounting frame 2, and the fixing component 6 on the turntable 5 is fixed to the male hinge of the hinge body 4, so that the male hinge can rotate around the rotating shaft between the male hinge and the female hinge with the fixing component 6 and the turntable 5. The load effect on the male hinge is simulated by the fixing component 6 and the turntable 5 and the additional weight added to the turntable 5, and the stability when testing a single door hinge is ensured by the turntable 5, thereby ensuring the accuracy of the load rotation test of the rotating shaft between the male hinge and the female hinge;

[0033] During the test, one of the striker rods 10 is used to push the push rod 11 on the fixed component 6, while the other striker rod 10 is located at a fixed position away from the push rod 11. In the process of the corresponding striker rod 10 pushing the push rod 11 to deflect the male hinge under load, the pressure value is monitored by the pressure sensor connected to the end of the corresponding striker rod 10, and the current value of the corresponding arc-shaped electric guide rail 8 is monitored. If the pressure value and the current value are within the normal threshold range, it indicates that the bearing capacity of the produced door hinge is within the compliance range; if the pressure value is too large or the current value is too large and exceeds the threshold, it indicates that the hinge body 4 is under load. The rotational resistance is too large, that is, the bearing capacity of the hinge body 4 is not compliant; and after the striker 10 pushes the fixing component 6 and the male hinge to rotate a certain angle, the striker 10 stops moving. At this time, the other striker 10 is stationary on the other side of the push rod 11, so that the loaded male hinge continues to swing forward naturally under the action of inertia until the push rod 11 hits the other striker 10. If the monitoring value of the pressure sensor corresponding to the other striker 10 is normal, it indicates that the bearing capacity of the hinge body 4 is compliant. If the monitoring value of the pressure sensor corresponding to the other striker 10 is too small, it indicates that the natural rotation resistance of the hinge body 4 is too large, that is, its bearing capacity is not compliant.

[0034] In summary, when testing the bearing capacity of a single hinge body 4, the turntable 5 is used to improve stability to avoid excessive load and offset affecting the accuracy of the rotation bearing capacity test. Two striker rods 10 are distributed on both sides of the push rod 11, so that one of the striker rods 10 pushes the push rod 11 to move a certain distance and then allows the push rod 11 to swing forward naturally, thereby performing a bearing capacity test while actively driving the male hinge to rotate, and also testing the bearing capacity of the male hinge under load and natural swinging, thereby improving the accuracy and effectiveness of the bearing capacity test of the hinge body 4.

[0035] In the present invention, a mounting plate 3 extending vertically downward is installed in the mounting frame 2, and two clamping blocks 12 are fixed on the mounting plate 3 toward the position of the hinge body 4. The clamping blocks 12 are adapted to the preset holes of the female hinge of the hinge body 4, and the thickness of the clamping blocks 12 is greater than the thickness of the female hinge. It should be noted that: the female hinge and the male hinge of the door hinge will have preset holes or grooves during the production process to fix the door when it is installed and used. The setting of the clamping blocks 12 on the mounting plate 3 is corresponding to the preset holes of the door hinge; an electric push rod 13 is horizontally installed at a position adjacent to the clamping block 12 in the mounting plate 3, and a clamping sleeve 16 is connected to the end of the electric push rod 13, and the clamping sleeve 16 has a clamping hole at one end toward the clamping block 12 Slot, it should be noted that: a connecting plate 14 is installed at the end of the telescopic shaft of the electric push rod 13, and an extension rod 15 is fixed between the connecting plate 14 and the clamping sleeve 16; in the initial state, the electric push rod 13 extends outward with the clamping sleeve 16 to separate the clamping sleeve 16 from the block 12, so as to facilitate the staff to insert the corresponding holes on the female hinge into the block 12 on the mounting plate 3, and then move the clamping sleeve 16 toward the block 12 through the electric push rod 13 and make the clamping sleeve 16 coincide with the end of the block 12, so as to clamp and fix the female hinge. Compared with the conventional method of manually tightening the bolts to perform a fixed test on the female hinge, the convenience of testing, installing and disassembling the hinge body 4 is effectively improved to improve work efficiency.

[0036] In the present invention, the electric push rod 13 is connected to a current monitoring module 1, which monitors the working current of the electric push rod 13. If the working current of the electric push rod 13 decreases abnormally, it indicates that the female hinge and the mounting plate 3 may be loose, and retesting is required. By monitoring the working currents of the two electric push rods 13, it can be inferred whether the female hinge is fixed and stable, thereby assisting in determining the accuracy and effectiveness of the test.

[0037] In the present invention, a linear electric guide rail 17 is installed on the turntable 5, and a fixed frame 18 extending vertically upward is connected to the linear electric guide rail 17. The push rod 11 is installed on the fixed frame 18 at a top position away from the hinge body 4. The fixed frame 18 is installed with two horizontally placed hydraulic push rods 19 toward the hinge body 4. The push rod 11 is located above the two hydraulic push rods 19. The two hydraulic push rods 19 are distributed in the vertical direction. The two hydraulic push rods 19 are respectively extended and retracted toward the two sides of the fixed frame 18. The end of the hydraulic push rod 19 is connected with a splint 20. The splint 20 is fixed with a positioning block 21 at the position of the male hinge facing the hinge body 4. The positioning block 21 corresponds to the position of the preset hole on the male hinge. The space between the two splints 20 The distance is extended at a position corresponding to the hydraulic push rod 19 to facilitate the closing operation of the two splints 20 through the two hydraulic push rods 19. In the initial state, the two splints 20 are opened, and the linear electric guide rail 17 is used to move the splint 20 outward to a placement position away from the hinge body 4. After the female hinge of the hinge body 4 is fixed, the male hinge is in the area between the two splints 20. The two splints 20 are moved toward the male hinge through the linear electric guide rail 17, and the two splints 20 are gradually closed through the hydraulic push rod 19. The male hinge can be corrected and positioned, thereby gradually positioning the male hinge at the initial position before the rotation test, thereby improving the accuracy of subsequent tests and improving the effectiveness of the test.

[0038] In the present invention, the hydraulic push rod 19 is connected to a current monitoring module 2, which is used to monitor the working current of the hydraulic push rod 19 in real time during testing. If the current value monitored by the current monitoring module 2 decreases abnormally, it indicates that looseness may have occurred between the splint 20 and the male hinge, and retesting is required to further assist in determining the effectiveness and accuracy of the test.

[0039] Example 2: Reference Figures 1-11, an auxiliary device for detecting the bearing force of a vehicle door hinge, based on Example 1, a mounting groove 22 with a circular cross-section is opened at the position corresponding to the turntable 5 on the top of the base 1, the outer diameter of the turntable 5 is smaller than the inner diameter of the mounting groove 22, that is, the outer wall of the turntable 5 does not contact the inner wall of the mounting groove 22, and two limit grooves 23 are opened at the bottom of the turntable 5. A cylinder 25 extending vertically upward is installed at the position corresponding to the limit groove 23 at the bottom of the mounting groove 22, and the top of the cylinder 25 is connected to the limit block 26. In the initial state, the cylinder 25 extends upward with the limit block 26. The two plywood 20 and the turntable 5 are fixed to the limit groove 23 and the horizontal and vertical positions of the turntable 5 are limited by the two cylinders 25. At this time, the positions of the linear electric guide 17 and the clamping plate 20 are corresponding to the position of the placed male hinge and are fixed. During the test, the limit block 26 is retracted downward by the cylinder 25 to separate it from the limit groove 23. At this time, the two clamping plates 20 are clamped and fixed to the male hinge, so that the clamping plate 20 and the turntable 5 can be kept fixed, thereby bearing the weight and avoiding the influence of the external friction of the turntable 5 on the test, thereby further improving the accuracy of the test.

[0040] In the present invention, a magnetic strip 24 is installed on the periphery of the bottom of the turntable 5, and a plurality of electromagnetic blocks 27 are installed at the position corresponding to the magnetic strip 24 at the bottom of the mounting groove 22. During the test, the electromagnetic blocks 27 are energized and magnetically attracted to the magnetic strip 24, thereby realizing the controllable load adjustment of the turntable 5 and the male hinge position by adjusting the power supply of the electromagnetic blocks 27.

[0041] In the present invention, the magnetic strip 24 is arranged into a ring structure, and a plurality of electromagnetic blocks 27 are distributed in a ring array in the mounting groove 22. Thus, through magnetic adsorption between the ring-shaped magnetic strip 24 and the ring-shaped array distributed electromagnetic blocks 27, when the turntable 5 deflects with the male hinge, the magnetic effect of the ring distribution is utilized to maintain the horizontal stability of the turntable 5, thereby improving the effectiveness and accuracy of the rotation test.
