Description

Technical Field

[0001] The present invention relates to the technical field of vehicle door correction, and in particular to a bulletproof vehicle door correction aid and method. Background Art

[0002] Bulletproof doors usually refer to adding special materials or structures inside the car doors to improve the bulletproof ability of the car doors and provide additional safety protection. Bulletproof doors are designed to reduce or prevent bullet penetration, thereby protecting the occupants from injury. This type of car door usually uses special materials in key parts, such as Kevlar and other bulletproof materials, to enhance its bulletproof performance. When the car door is processed, it needs to be welded to make the raw materials into the shape of the car door. Due to inconsistent material properties and welding deformation, the bulletproof door will have angle tolerances, unsatisfactory door flatness, and inconsistent gaps between the door and the side panel after welding. These factors have a great impact on the door seal, and in severe cases will cause the door seal to fail and leak. In the process of correcting the door, it is necessary to hammer the door frequently, which can easily cause the auxiliary tool to move, and the internal structure of the correction auxiliary tool is complex, which is not convenient to hammer the door from the bottom for correction, and when fixing the door, it usually contacts the outside of the door, which can easily cause scratches or marks on the door.

[0040] In the embodiment of the present disclosure, as shown in FIG* and FIG*, the following steps are included:

[0041] 01. First, the assistive device body 1 is controlled to move to the position where it needs to be used through the moving wheel 103 and the universal wheel, and then the locking structure of the universal wheel is controlled to open to fix the universal wheel;

[0042] 02. Control the hand wheel 104 to rotate. The hand wheel 104 controls the force-bearing component 105, the moving component 106, the fixed head component 107 and the limit head 108 to move downward together, so that the fixed head component 107 and the moving wheel 103 are in anti-slip contact, and the pyramid-shaped rod at the bottom of the limit head 108 is in anti-slip contact with the ground, thereby improving the fixing effect of the auxiliary tool body 1 and avoiding the displacement of the auxiliary tool body 1 when hammering;

Since the contact plate 307 is made of rubber, it will not cause marks and scratches on the top of the door. Firmly press the door, then hammer the door bending line and re-measure with an angle ruler. If the angle is too large, put a shim at the door bending position, and then press the door again;

[0044] 04.

[0046] The working principle of this embodiment is as follows: when the bulletproof door needs to be corrected, the auxiliary tool body 1 can be controlled to move to the position where it needs to be used through the moving wheel 103 and the universal wheel, and then the locking structure of the universal wheel can be controlled to open to fix the universal wheel, and then the hand wheel 104 can be controlled to rotate. The hand wheel 104 controls the force-bearing component 105, the moving component 106, the fixed head component 107 and the limit head 108 to move downward together, so that the fixed head component 107 and the moving wheel 103 are in non-slip contact, and the pyramid-shaped rod at the bottom of the limit head 108 is in non-slip contact with the ground, thereby improving the fixing effect of the auxiliary tool body 1 and avoiding the displacement of the auxiliary tool body 1 when hammering. Then, the bulletproof door that needs to be corrected is controlled to be placed above the internal component 2 and the support plate 204, and then the positioning pin 205 is controlled to be inserted into the inside of the door and the support plate 204 at the same time, so that the door is positioned and supported and fixed, and then Use an angle ruler to measure the angle of the car door. If the angle is too small, control the lower pressure arm structure 303 to flip so that the fixing rod 304 fixes the lower pressure arm structure 303, so that the pressure block structure 306 and the contact plate 307 are subjected to force together and contact with the top of the car door. Since the contact plate 307 is made of rubber, it will not cause marks and scratches on the top of the car door. Firmly press the car door, then hammer the bending line of the car door and re-measure with an angle ruler. If the angle is too large, put a shim at the bending point of the car door, and then press the car door again. Control the guide component 202 installed in the appropriate position of the adjustment component 206 through the control part 208 to be freely pulled, so that the electric cylinder 207 moves to the appropriate position, control the electric cylinder 207 to operate, lift the bottom of the car door, instead of hammering, and conveniently complete the correction of the car door. Then use a feeler gauge to measure the gap between the door edge circle and the two planes, and ensure that the edge gap meets the requirements by hammering the high point of the edge.

After the fixing rod (304) flips forward, it presses the lower pressure arm structure (303) to fix it, and after the fixing rod (304) flips backward, it contacts the contact block (302).

10. A method for calibrating a bulletproof door aid as claimed in claim 9, characterized in that: The following steps are involved:

01. First, the auxiliary tool body (1) is controlled to move to the position where it is needed through the moving wheel (103) and the universal wheel, and then the locking structure of the universal wheel is controlled to open to fix the universal wheel; 02. Control the hand wheel (104) to rotate, and the hand wheel (104) controls the force-bearing component (105), the moving component (106), the fixed head component (107) and the limit head (108) to move downward together, so that the fixed head component (107) and the moving wheel (103) are in anti-slip contact, and the pyramid-shaped rod at the bottom of the limit head (108) is in anti-slip contact with the ground, thereby improving the fixing effect of the auxiliary tool body (1) and avoiding the displacement of the auxiliary tool body (1) when hammering; 03. Place the bulletproof door to be corrected above the internal component (2) and the support plate (204), then control the positioning pin (205) to be inserted into the door and the support plate (204) at the same time, so that the door is positioned and supported, and then use an angle ruler to measure the angle of the door. If the angle is too small, control the lower pressure arm structure (303) to flip, so that the fixing rod (304) fixes the lower pressure arm structure (303), so that the pressing block structure (306) and the contact plate (307) are stressed together and contact the top of the door. Since the contact plate (307) is made of rubber, it will not cause marks and scratches on the top of the door. Firmly press the door, then hammer the door bending line and re-measure with an angle ruler. If the angle is too large, put a shim at the door bending position, and then press the door again; 04. The guide member (202) installed at the appropriate position of the adjusting member (206) is freely pulled out by the operating member (208), so that the electric cylinder (207) moves to the appropriate position, and the electric cylinder (207) is controlled to operate to lift the bottom of the door instead of hammering; 05. After completing the calibration of the car door, use a feeler gauge to measure the gap between the door edge and the two planes. Hammer the high point of the edge to ensure that the edge gap meets the requirements. At this point, the use of the auxiliary tool is completed.
