The operation is simple and convenient to promote and use.

[0032] like Figure 1-Figure 5 As shown, the assembly inspection tool 100 of the vehicle door assembly according to the present invention comprises: a vehicle door mounting frame 1 and a vehicle window mounting frame 2 .

[0033] The door mounting frame 1 is used to install the door, and the window mounting frame 2 is used to install the window glass 8. The window mounting frame 2 is movably connected to the door mounting frame 1, and the window mounting frame 2 can be installed above the door mounting frame 1, so that the door mounting frame 1 can position the door at the bottom, and the window mounting frame 2 can position the window glass 8 at the top. Among them, the window mounting frame 2 and the door mounting frame 1 are selectively fixed by the positioning structure, that is, after the window mounting frame 2 and the door mounting frame 1 are connected, they can move relative to each other, and when the window mounting frame 2 and the door mounting frame 1 need to be relatively fixed, the positioning structure can be used to relatively fix the two, so that the installed door and the window glass 8 are relatively fixed, and the window glass 8 is prevented from shaking relative to the door after being positioned.

[0034] The vehicle door mounting frame 1 is provided with a rotating tensioning structure 11 and a plurality of fixed tensioning structures 12 . The plurality of fixed tensioning structures 12 are used to respectively tension and position the vehicle doors supported on the vehicle door mounting frame 1 . The rotating tensioning structure 11 is used to clamp and fix the vehicle doors.

[0035] That is to say, when installing the vehicle door on the vehicle door mounting frame 1, the vehicle door can be supported on the vehicle door mounting frame 1 first, such as providing a support block 16 on the vehicle door mounting frame 1 to support the bottom of the vehicle door, such as Figure 1 and Figure 2 As shown, two support blocks 16 can be provided and spaced apart at the bottom of the vehicle door mounting frame 1, and the vehicle door is supported on the two support blocks 16; further, the vehicle door can be positioned and tightened by means of a fixed tightening structure 12, and the fixed tightening structure 12 tightens and positions the vehicle door by applying a tightening force to the vehicle door, thereby increasing the tension of the tooling on the vehicle door, and the fixed tightening structure 12 can be provided in plurality, that is, it can be provided in two, three or more, so that the vehicle door can be positioned and fixed relative to the vehicle door mounting frame 1 at multiple positions, thereby realizing the installation of the vehicle door.

[0036] Furthermore, after the vehicle door is positioned by means of a plurality of fixed tensioning structures 12, the vehicle door can be further clamped and fixed by means of a rotating tensioning structure 11 by clamping the vehicle door in the rotating tensioning structure 11. It can be understood that after the vehicle door is positioned by means of a plurality of fixed tensioning structures 12, if there is a situation where there is insufficient support and tensioning force for positioning, a rotating tensioning structure 11 can be provided at a blank position offset from the fixed tensioning structure 12 to further clamp and position the vehicle door, thereby effectively improving the reliability of the positioning and fastening of the vehicle door and ensuring the stability of the position state of the vehicle door.

[0037] Further, the vehicle window mounting frame 2 is provided with a detection member 21 and a plurality of first positioning members 22, wherein the plurality of first positioning members 22 are used to position the vehicle window glass 8 respectively, and the detection member 21 is used to detect the vehicle window glass 8. Among them, the first positioning members 22 are provided in plurality, that is, they can be provided in two, three or more, and the plurality of first positioning members 22 are respectively provided at the outer edge of the vehicle window mounting frame 2, so that the vehicle window glass 8 can be stably installed and accurately positioned on the vehicle window mounting frame 2. It should be noted that the vehicle window glass 8 is installed on the vehicle door in a liftable manner so that the vehicle window glass 8 can be lifted and lowered relative to the vehicle door, and the plurality of first positioning members 22 can be provided in the upper area of ​​the vehicle window mounting frame 2, thereby, when positioning and installing a vehicle door without a frame of the vehicle window glass 8, the vehicle door is first positioned on the vehicle door mounting member, and then the vehicle window glass 8 is lifted upward to the target position and then positioned against the plurality of first positioning members 22 on the vehicle window mounting frame 2, so that the vehicle window glass 8 can be positioned and ensured to be in a stable position. Among them, a detection component 21 is set on the vehicle window mounting frame 2, and the relative surface difference and gap of the vehicle window glass 8 after positioning and installation can be detected to improve the positioning accuracy of the vehicle window glass 8, and the detection component 21 can be set to one or more, such as a plurality of detection components 21 can be spaced apart and distributed at the outer edge of the vehicle window mounting frame 2, so as to realize feedback and inspection of the positioning effect, and further improve the positioning accuracy of the vehicle window glass 8.

[0038] In a specific design, the first positioning member 22 can be configured as a positioning column, and the outer peripheral wall of the positioning column can be pressed against the edge of the vehicle window glass 8. The fixing and tightening structure 12 can be configured to include a suction cup or other types of structural members to be fixed relative to the vehicle door, and then the vehicle door is tightened and positioned by pulling the suction cup or other structural members.

[0039] According to the assembly inspection tool 100 of the vehicle door assembly of the embodiment of the utility model, by arranging a rotating tensioning structure 11 on the vehicle door mounting frame 1, in cooperation with a plurality of fixed tensioning structures 12, the vehicle door can be stably mounted on the vehicle door mounting frame 1, and the mounting state of the vehicle door is reliable. At the same time, a detection component 21 is arranged on the vehicle window mounting frame 2, so that the position, surface difference and gap of the vehicle window glass 8 after lifting and positioning can be synchronously detected, thereby improving the positioning accuracy of the vehicle window glass 8. The operation is simple and convenient for popularization and use.

[0040] In some embodiments, the rotary tensioning structure 11 includes a fixed part 114 and a movable part. The fixed part 114 is relatively fixed to the vehicle door mounting frame 1. The movable part is connected to the fixed part 114 and together forms a clamping gap 13 for clamping the vehicle door. The movable part is movable relative to the fixed part 114 and the clamping gap 13 is adjustable. That is to say, the rotary tensioning structure 11 is fixedly mounted on the vehicle door mounting frame 1 by the fixed part 114. The movable range of the movable part is used to adjust the size of the clamping gap 13 between the movable part and the fixed part, so that the movable part is moved away from or close to the fixed part, thereby increasing or reducing the clamping gap 13, thereby achieving clamping or loosening of the vehicle door.

[0041] Specifically, Figure 1 As shown, the rotating tensioning structure 11 can be arranged at the edge of the large opening of the door mounting frame 1 to increase the support and tensioning force of the door, avoid interfering with the components of the door and facilitate the tensioning action of the rotating tensioning structure 11, so that the door can be stably installed on the door mounting frame 1. Figure 4 As shown, the rotating tensioning structure 11 includes a fixing member 114 and a movable member. The movable member can be installed on the upper part of the fixing member 114. The movable member and the fixing part are connected and a clamping gap 13 is formed between them. The fixing member 114 is fixedly mounted on the vehicle door mounting frame 1, so that the rotating tensioning structure 11 is fixedly mounted on the vehicle door mounting frame 1. When the vehicle door is actually installed, the fixing member 114 and the vehicle door mounting frame 1 are relatively stationary, and the movable member moves relative to the fixing member 114. The movable part clamps the vehicle door between the clamping gap 13 during the movement.

[0042] Among them, in actual design, the fixing member 114 can be configured to be fixed on the vehicle door mounting frame 1 by means of screws, bolts, etc., which is convenient and flexible to disassemble, and other connection methods can also be selected for fixing.

[0043] In some embodiments, the movable part includes a screwing portion 111, a rod body portion 112 and a clamping portion 113. The rod body portion 112 is inserted into the fixing member 114 and is threadedly connected to the fixing member 114. The screwing portion 111 and the clamping portion 113 are respectively connected to the two ends of the rod body portion 112. A clamping gap 13 is formed between the clamping portion 113 and the fixing member 114.

[0044] like Figure 4As shown, the twisting portion 111 is located at the left end of the rod body 112, and the clamping portion 113 is located at the right end of the rod body 112. The twisting portion 111 is fixedly connected to the rod body 112, that is, when the twisting portion 111 is rotated, the twisting portion 111 can drive the rod body 112 to rotate accordingly, wherein the rod body 112 is provided with an external thread, and the fixing member 114 is provided with a through hole adapted to the rod body 112, and the through hole is provided with an internal thread, so that the rod body 112 can pass through the fixing member 114 and be connected to the fixing member 114 by a thread, so that when the rod body 112 rotates, the clamping portion 113 at the right end is driven to move relative to the fixing member 114, and the clamping portion 113 can move away from or close to the fixing portion to adjust the clamping gap 13 between the clamping portion 113 and the fixing member 114, thereby achieving clamping or releasing the door. Specifically, the rod body 112 is as shown in FIG. Figure 4 When the rod body 112 moves to the left, the clamping gap 13 between the clamping portion 113 and the fixing portion is reduced. Figure 4 When the clamping portion 113 moves to the right, the clamping gap 13 between the clamping portion 113 and the fixing portion is enlarged.

[0045] like Figure 4 As shown, in a specific design, a nut 14 can be provided at the right end of the rod body 112. The nut 14 can prevent the clamping part 113 from being separated from the rod body 112 during movement, and the nut 14 is provided to facilitate the disassembly of the clamping part 113 and the rod body 112. The moving direction of the clamping part 113 when the rod body 112 rotates can be adjusted by setting the thread rotation direction of the rod body 112 and the threaded hole, thereby adjusting the clamping gap 13 between the clamping part 113 and the fixing member 114.

[0046] In some embodiments, the assembly inspection tool 100 of the vehicle door assembly also includes an elastic member 115, which is sleeved on the outside of the rod body 112 and elastically connected between the twisting portion 111 and the fixing member 114, so that the elastic member 115 can apply an elastic force between the twisting portion 111 and the fixing member 114, thereby making the twisting portion 111 and the fixing member 114 relatively pre-tightened, ensuring that the rod body 112 and the fixing member 114 are always in close contact. At the same time, the elastic force of the elastic member 115 can prevent the rod body 112 from rotating relative to the fixing member 114, thereby achieving pre-tightening of the relative position of the movable part and the fixing member 114.

[0047] Specifically, Figure 4As shown, the elastic member 115 is sleeved on the outer side of the rod body 112 between the twisting portion 111 and the fixing member 114, and is adapted to the size of the rod body 112. One end of the elastic member 115 is pressed against the twisting portion 111, and the other end is pressed against the fixing member 114. When the vehicle door is actually installed, after the vehicle door is placed in a fixed position, a plurality of fixed tensioning structures 12 are first pressed to tighten and position the vehicle door, and then the twisting portion 111 is rotated to adjust the clamping gap 13 between the clamping portion 113 and the fixing member 114, so that the vehicle door is clamped between the clamping portion 113 and the fixing member 114. At this time, the spring is squeezed between the twisting portion 111 and the fixing portion and deformed, generating an elastic force to restore the deformation. The elastic force acts on the twisting portion 111, thereby further increasing the clamping force, so that the vehicle door is clamped between the fixing member 114 and the clamping portion 113.

[0048] In some embodiments, one of the window mounting frame 2 and the door mounting frame 1 is provided with a sliding guide rail 3 and the other is provided with a sliding block 4, the sliding block 4 slides with the sliding guide rail 3 and makes the window mounting frame 2 movable relative to the door mounting frame 1, that is, the sliding guide rail 3 can be set on the window mounting frame 2, and the sliding block 4 can be set on the door mounting frame 1, or the sliding block 4 can be set on the window mounting frame 2, and the sliding guide rail 3 can be set on the door mounting frame 1, wherein the sliding block 4 slides on the sliding guide rail 3 so that the window glass 8 installed on the window mounting frame 2 can be moved relative to the door mounting frame 1, so as to position and detect the window glass 8.

[0049] Specifically, Figure 2 and Figure 3 As shown, two sliding rails 3 are provided at the upper and lower regions of the vehicle window mounting frame 2, and the two sliding rails 3 are parallel to each other, a sliding block 4 is provided on the sliding rail 3 in the upper region, and three sliding blocks 4 are provided on the sliding rail 3 in the lower region, and the middle sliding block 4 corresponds to the position of the upper sliding block 4, so as to increase the stability of the vehicle window mounting frame 2 when it moves relative to the vehicle door mounting frame 1, and facilitate the adjustment of the vehicle window glass 8 on the vehicle window mounting frame 2 without offset, and then the vehicle window glass 8 is pressed against the first positioning member 22 as a whole, and then the detection member 21 in the figure is used for detection, thereby realizing the positioning and detection of the vehicle window glass 8. It should be noted that the number of sliding rails 3 and sliding blocks 4 is not limited to that described in this embodiment, and can be flexibly selected according to actual conditions and needs.

[0050] In some embodiments, the positioning structure includes a second positioning member 5 and a positioning plate 6, the second positioning member 5 is movably mounted on one of the vehicle window mounting frame 2 and the vehicle door mounting frame 1, and the positioning plate 6 is disposed on the other of the vehicle window mounting frame 2 and the vehicle door mounting frame 1. That is, the second positioning member 5 is mounted on the vehicle window mounting frame 2, and the positioning plate 6 is disposed on the vehicle door mounting frame 1, or the second positioning member 5 is mounted on the vehicle door mounting frame 1, and the positioning plate 6 is mounted on the vehicle window mounting frame 2, and the second positioning member 5 is movable relative to the positioning plate 6.

[0051] The second positioning member 5 is threadedly connected to the positioning plate 6, that is, the second positioning member 5 is provided with threads, and the positioning plate 6 is provided with threaded through holes adapted to the second positioning member 5, so that the positioning member can pass through the threaded through holes and be threadedly connected to the second positioning member 5, wherein, in the specific design, the second positioning member 5 can be constructed as screws, bolts, etc.

[0052] Specifically, Figure 1 and Figure 3 As shown, the positioning plate 6 can be designed to be composed of two surfaces connected by vertical bends, one side can be fixed on the vehicle window mounting frame 2 by screws or bolts to facilitate disassembly and installation, and the other side passes through the empty space of the vehicle window mounting frame 2 to be connected to the second positioning member 5.

[0053] In some embodiments, one of the vehicle window mounting frame 2 and the vehicle door mounting frame 1 is provided with a mounting plate 7 , the mounting plate 7 is provided with a movable hole, and the second positioning member 5 is passed through the movable hole.

[0054] Specifically, Figure 3 As shown, a mounting plate 7 is provided in the door mounting frame 1 and the mounting plate 7 is fixedly installed at the upper edge of the door mounting frame 1. The mounting plate 7 can be fixedly connected to the sliding block 4, so that when the sliding block 4 slides on the sliding guide rail 3, the door mounting frame 1 as a whole moves relative to the window mounting frame 2, and a movable hole is provided on the mounting plate 7 for the second positioning member 5 to pass through. The distance between the positioning plate 6 and the mounting plate 7 can be adjusted by the second positioning member 5, and then the moving distance of the sliding block 4 on the sliding guide rail 3 can be adjusted, so that the window mounting frame 2 can be positioned with the door mounting frame 1 through the second positioning member 5, which solves the sliding problem of the window mounting frame 2 due to the sliding guide rail 3 when the window glass 8 is assembled on the window mounting frame 2, and reduces the time required for workers to adjust the window mounting frame 2 to assemble the window glass 8.

[0055] In some embodiments, the assembly inspection tool 100 of the vehicle door assembly further includes an edge stopper 23, which is installed on a side of the vehicle window mounting frame 2 close to the vehicle door mounting frame 1, and the edge stopper 23 is adapted to be limited and pressed against the edge of the vehicle door mounting frame 1 when the vehicle window mounting frame 2 moves to the maximum position relative to the vehicle door mounting frame. Figure 1As shown, the edging limiter 23 is installed at the bottom position of the right end of the window mounting frame 2, and is pressed against the upper right edge of the door mounting frame 1 to limit the moving position of the window mounting frame 2. During the actual installation, after the door is fixed on the door mounting frame 1, the position of the window mounting frame 2 relative to the door mounting frame 1 is adjusted by the sliding guide rail 3, and then the position of the edging limiter 23 is compared to determine whether the door is fine-tuned in place.

[0056] In some embodiments, there are three fixed tensioning structures 12 distributed in a three-point manner, and the rotating tensioning structure 11 is distributed spaced apart from the line connecting any two of the three fixed tensioning structures 12, that is, the three fixed tensioning structures 12 and the rotating tensioning structure 11 are independently distributed at a certain distance to achieve stable and precise installation of the vehicle door.
