In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figure 1 As shown, the present invention provides a vehicle door removal auxiliary tool, comprising a first handle 100 and a second handle 200. The first handle 100 is provided with a clamping portion 110 at its end, and the clamping portion 110 is used to clamp the hinge; the handle body of the second handle 200 is rotatably connected to the handle body of the first handle 100, and the second handle 200 is provided with a lifting pin 210 at one end close to the clamping portion 110, and the lifting pin 210 is used to lift the latch of the hinge.

[0027] The vehicle door dismantling auxiliary tool provided by the present invention, when in use, the clamping portion 110 clamps the hinge, and then the second handle 200 is rotated relative to the first handle 100, and the second handle 200 drives the lifting pin 210 to gradually approach the hinge and lift the latch of the hinge, at which time the hinge is disassembled, and the vehicle door is smoothly taken out. At the end of use, the second handle 200 is rotated in the opposite direction relative to the first handle 100, and the second handle 200 drives the lifting pin 210 to gradually move away from the hinge, and then the hinge is removed from the clamping portion 110, and the vehicle door dismantling auxiliary tool dismantles the next vehicle door. The operator can dismantle the vehicle door quickly and efficiently through the vehicle door dismantling auxiliary tool, which improves the operator's work efficiency.

[0028] The first handle 100 and the second handle 200 are produced by aluminum alloy technology, and the lifting pin 210 is made of 45 steel after quenching and tempering.

[0029] In some embodiments, the clamping portion 110 includes two clamping arms 111, the two clamping arms 111 are arranged at intervals, and a clamping space is formed between the two clamping arms 111, and the clamping space is used to accommodate the hinge. Through the above structure, when in use, the hinge is placed in the clamping space formed by the two clamping arms 111, and the two clamping arms 111 clamp the hinge. The clamping arm 111 is provided with a polyurethane protective cover 112. By providing the polyurethane protective cover 112, the hinge surface can be effectively protected to prevent the clamping arm 111 from damaging the hinge.

[0030] The handle of the first handle 100 is provided with a first connection hole, the handle of the second handle 200 is provided with a second connection hole aligned with the first connection hole, and the rotating shaft 220 passes through the first connection hole and the second connection hole, so as to realize the rotation connection between the handle of the second handle 200 and the handle of the first handle 100. The two ends of the rotating shaft 220 are respectively provided with a first stopper and a second stopper, the first stopper abuts against the side of the first handle 100 away from the second handle 200, and the second stopper abuts against the side of the second handle 200 away from the first handle 100. By providing the first stopper and the second stopper, the rotating shaft 220 can be axially limited, and the rotating shaft 220 can be prevented from being separated from the first connection hole and the second connection hole.

[0031] The first stopper and the second stopper are both detachably connected to the rotating shaft 220, so as to facilitate the disassembly and assembly of the rotating shaft 220. The first connecting hole and the second connecting hole are both rotatably matched with the rotating shaft 220.

[0032] In some embodiments, the handle of the second handle 200 is provided with a positioning pin 230, and when the lifting pin 210 lifts the latch of the hinge, the positioning pin 230 abuts against the first handle 100. By providing the positioning pin 230, when in use, the clamping portion 110 clamps the hinge, and then the second handle 200 is rotated relative to the first handle 100, and the second handle 200 drives the lifting pin 210 to gradually approach the hinge and lift the latch of the hinge. At this time, the positioning pin 230 abuts against the first handle 100, and the positioning pin 230 limits the rotation path of the second handle 200 to prevent the end of the second handle 200 from squeezing the hinge, which can protect the hinge surface.

[0033] The standard parts used in the present invention can all be purchased from the market, and the special-shaped parts can all be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt mature means in the prior art, and the machinery, parts and equipment adopt conventional models in the prior art. The circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
