[0036] The back door assembly device according to the embodiments of the present application is described below with reference to the drawings.

[0037] As shown in Figures 1 to 12 The back door assembly device according to the embodiments of the present application, the back door 30 is connected to the vehicle body 50 through the hinge 40, and the back door assembly device comprises: a first assembly component 10 and a second assembly component 20, the hinge 40 is adapted to be positioned at the mounting position on the vehicle body 50 through the first assembly component 10, the first assembly component 10 comprises a first tool body 11 and a first positioning component 12 and a second positioning component 13 arranged on the first tool body 11, the first positioning component 12 is used to position the position of the hinge 40 on the first assembly component 10, and the second positioning component 13 is used to position the position of the first assembly component 10 on the vehicle body 50, the back door 30 is adapted to be positioned at the position on the vehicle body 50 through the second assembly component 20, the second assembly component 20 comprises a second tool body 21 and a third positioning component and a fourth positioning component arranged on the second tool body 21, the third positioning component is used to position the position of the second assembly component 20 on the vehicle body 50, and the fourth positioning component is used to position the position of the back door 30 on the second assembly component 20.

[0038] That is, the hinge 40 can be positioned at the mounting position on the vehicle body 50 through the first assembly component 10 to ensure the mounting position accuracy of the hinge 40 on the vehicle body 50, and the back door 30 can be positioned at the position on the vehicle body 50 through the second assembly component 20 to ensure the mounting position accuracy of the back door 30 on the vehicle body 50, that is, the hinge 40 and the back door 30 are respectively positioned and installed with the vehicle body 50 by using the first assembly component 10 and the second assembly component 20.

[0039] Therefore, in the process of assembling the hatchback door 30 to the vehicle body 50, the hinge 40 can be first installed on the vehicle body 50 through the first assembly assembly 10, and since the hinge 40 is not connected with the hatchback door 30 at this time, the first assembly assembly 10 can be provided with a larger arrangement space, for example, when the first hinge arm 41 connected with the vehicle body 50 needs to be tightened in the X direction, the first assembly assembly 10 can be increased with a limiting structure limiting the freedom of movement of the first hinge arm 41 in the Z direction and the Y direction, that is, the first assembly assembly 10 can improve the positioning accuracy of the hinge 40 by increasing the corresponding positioning limiting structure according to the installation requirements of the hinge 40, so as to improve the installation position accuracy of the hinge 40 on the vehicle body 50, thereby improving the assembly qualification rate of the hatchback door 30 and improving the overall assembly efficiency of the vehicle. At the same time, the installation of the hinge 40, such as bolting, can provide a larger operation space, which can reduce the assembly difficulty of the hinge 40 and improve the assembly efficiency. After the installation of the hinge 40 is completed, the position of the hatchback door 30 on the vehicle body 50 is positioned through the second assembly assembly 20 to realize the positioning between the hatchback door 30 and the hinge 40, and the connection between the hatchback door 30 and the hinge 40 is performed, and the process of installing the hatchback door 30 to the vehicle body 50 is completed.

[0040] Specifically, in the process of installing the hatchback door 30 to the vehicle body 50, the hinge 40 can be first positioned through the first positioning assembly 12 to maintain the relative position between the hinge 40 and the first assembly assembly 10, and then the first assembly assembly 10 is positioned on the vehicle body 50 through the second positioning assembly 13 to maintain the relative position between the first assembly assembly 10 and the vehicle body 50, so that the first assembly assembly 10 can accurately position the position of the hinge 40 on the vehicle body 50, and then the hinge 40 is fixed on the vehicle body 50 through the bolt. After the installation of the hinge 40 is completed, the cooperation between the first assembly assembly 10 and the hinge 40 and the vehicle body 50 is released, so as to disassemble the first assembly assembly 10 from the vehicle body 50, and the second assembly assembly 20 is positioned on the vehicle body 50 through the third positioning assembly to maintain the relative position between the second assembly assembly 20 and the vehicle body 50, and then the position of the hatchback door 30 on the second assembly assembly 20 is positioned through the fourth positioning assembly to maintain the relative position between the hatchback door 30 and the second assembly assembly 20, so that the second assembly assembly 20 can accurately position the position of the hatchback door 30 on the vehicle body 50. Since the hinge 40 has been fixedly installed on the vehicle body 50 at this time, the positioning between the hatchback door 30 and the hinge 40 can be realized at the same time, and the hatchback door 30 and the hinge 40 are connected through the bolt. After the connection between the hinge 40 and the hatchback door 30 is completed, the hatchback door 30 is lifted upward to release the cooperation between the hatchback door 30 and the fourth positioning assembly, and the cooperation of the third positioning assembly for the vehicle body 50 is released, so as to disassemble the second assembly assembly 20 from the vehicle body 50. Thus, the assembly process of the hatchback door 30 is completed.

[0041] According to the backhitch door assembling device, the hinge 40 can be installed on the vehicle body 50 through the first assembling component 10 first, since the hinge 40 is not connected with the backhitch door 30 at this time, a larger arrangement space can be provided for the first assembling component 10, the first assembling component 10 can improve the positioning precision of the hinge 40 according to the installation requirement of the hinge 40 by increasing the corresponding positioning limiting structure, so that the installation position precision of the hinge 40 on the vehicle body 50 is improved, and after the installation of the hinge 40 is completed, the position of the backhitch door 30 on the vehicle body is positioned through the second assembling component 20, so that the positioning between the backhitch door 30 and the hinge 40 is realized, that is, the hinge 40 and the backhitch door 30 are positioned and installed on the vehicle body 50 by using the first assembling component 10 and the second assembling component 20 respectively, and the installation precision is effectively improved. Meanwhile, a larger operation space can be provided for the installation, such as bolt tightening, of the hinge 40, the assembling difficulty of the hinge 40 can be reduced, and the assembling efficiency is improved.

[0042] In one specific example, the number of the first positioning components 12 is the same as and one-to-one corresponds to the number of the hinges 40 required for the installation of the backhitch door 30. For example, the backhitch door 30 needs to be fixed on the vehicle body 50 by two hinges 40 arranged at intervals along the left-right direction, and the first assembling component 10 is provided with two first positioning components 12 arranged at intervals along the left-right direction, which position the two hinges 40 respectively, so that the first assembling component 10 can simultaneously position the installation positions of multiple hinges 40 on the vehicle body 50, so as to improve the assembling efficiency.

[0043] According to some embodiments of the present application, Figure 2 and Figure 3As shown, the hinge 40 comprises a first hinge arm 41 and a second hinge arm 42 connected with the vehicle body 50 and the back door 30 respectively, the first hinge arm 41 is formed with a first assembly hole 411 extending along the front-rear direction, the first assembly hole 411 is used for connecting with the vehicle body 50, the first positioning assembly 12 is formed with an assembly avoiding space 121 extending along the front-rear direction, the assembly avoiding space 121 is located at the rear side of the first hinge arm 41 of the hinge 40 used for connecting with the vehicle body 50, and the assembly avoiding space 121 is arranged opposite to the first assembly hole 411 of the first hinge arm 41 used for connecting with the vehicle body 50. That is to say, the assembly avoiding space 121 can provide an operation space for the connection of the first assembly hole 411 and the vehicle body 50, and it can be understood that the hinge 40 is installed at the rear end of the upper transom 51 of the vehicle body 50 located at the rear door hole, so after the installation position of the hinge 40 on the vehicle body 50 is positioned by the first assembly assembly 10, a tightening device such as an electric wrench can be used to tighten the bolt to fix the first hinge arm 41 on the vehicle body 50 through the assembly avoiding space 121 to the first assembly hole 411 from the rear side of the first assembly assembly 10, so that the positioning accuracy of the hinge 40 on the vehicle body 50 can be ensured, the installation difficulty of the hinge 40 and the vehicle body 50 can be reduced, and the assembly efficiency of the hinge 40 can be improved.

[0044] According to some embodiments of the present application, the hinge 40 comprises a first hinge arm 41 and a second hinge arm 42 connected with the vehicle body 50 and the back door 30 respectively, the first positioning assembly 12 comprises a positioning clamping mechanism 122 and a first positioning block 123, the positioning clamping mechanism 122 is used for positioning and fixing the second hinge arm 42 of the hinge 40 used for connecting with the back door 30, and the first positioning block 123 is located at the front side of the positioning clamping mechanism 122 and abuts against the first hinge arm 41 of the hinge 40 used for connecting with the back door 30 along the up-down direction. Among them, after the second hinge arm 42 is fixed by the positioning clamping mechanism 122, since the first hinge arm 41 and the second hinge arm 42 can only be arranged opposite to each other, the rotation axis of the second hinge arm 42 relative to the first hinge arm 41 extends along the left-right direction, therefore, by abutting the first positioning block 123 against the first hinge arm 41 along the up-down direction, the rotation of the first hinge arm 41 relative to the second hinge arm 42 can be better limited. In other words, on the basis of fixing the second hinge arm 42 by the positioning clamping mechanism 122, only one first positioning block 123 can realize the fixation of the first hinge arm 41, so that the structure for fixing the first hinge arm 41 can be better simplified, the structure of the first positioning assembly 12 can be simplified, and the production cost of the first assembly assembly 10 can be reduced.

[0045] According to some embodiments of the utility model, positioning and clamping mechanism 122 includes first clamping block 1221, first positioning pin 1222 and first clamping unit 1223, first positioning pin 1222 is located on the bottom surface of first clamping block 1221 and is suitable for with second hinge arm 42 insertion joint cooperation, first clamping unit 1223 is located at the lower side of first clamping block 1221 and has first clamping position and first avoiding position, in first clamping position, first clamping unit 1223 and first clamping block 1221 jointly define first clamping space for clamping second hinge arm 42, in first avoiding position, first clamping unit 1223 is located at the rear side of first clamping block 1221, the bottom surface of first positioning block 123 constitutes first positioning surface, and first positioning surface is suitable for with first hinge arm 41 along up-down direction abuts.

[0046] That is to say, when installing second hinge arm 42 to positioning and clamping mechanism 122, control first clamping unit 1223 switches to first avoiding position, in order to align second hinge arm 42 with first positioning pin 1222 and make first positioning pin 1222 insert second hinge arm 42, thereby realize the positioning between second hinge arm 42 and first assembly component 10, first positioning pin 1222 extends along up-down direction, can better limit the activity freedom degree of second hinge arm 42 in front and back and left and right directions, and the upper surface of first hinge arm 41 is controlled to abut against first positioning surface, and then first clamping unit 1223 is controlled to switch to first clamping position, so that first clamping unit 1223 and first clamping block 1221 jointly cooperate to clamp and fix second hinge arm 42 from both sides, to limit the activity freedom degree of second hinge arm 42 in up-down direction, that is, through positioning and clamping mechanism 122, six-way fixation of second hinge arm 42 can be realized.

[0047] Meanwhile, through the blocking of first positioning surface to first hinge arm 41, first hinge arm 41 cannot be turned positively or reversely relative to second hinge arm 42, so as to stably fix hinge 40 on first assembly component 10. After the connection between hinge 40 and vehicle body 50 is completed, first assembly component 10 can be pulled out upward by controlling first clamping unit 1223 to switch to first avoiding position. Since first clamping unit 1223 is located at the rear side of first clamping block 1221 when being in first avoiding position, interference between first clamping unit 1223 and vehicle body 50 in first avoiding position can be avoided. Therefore, by controlling first clamping unit 1223 to switch between first clamping position and first avoiding position, the difficulty of installing hinge 40 to first assembly component 10 and disconnecting hinge 40 from first assembly component 10 can be reduced while ensuring the stability of hinge 40 fixed by first assembly component 10, so as to improve the assembly efficiency of hinge 40.

[0048] According to some embodiments of the utility model, first positioning assembly 12 still includes second positioning block 124, second positioning block 124 is arranged with positioning clamping mechanism 122 along left and right direction and is located first positioning block 123 rear side, the end face of second positioning block 124 front side constitutes second positioning face, second positioning face is suitable for abutting in first hinged arm 41 rear side. Among them, the rotation axis of first hinged arm 41 relative to second hinged arm 42 extends along left and right direction, after second positioning face and first hinged arm 41 rear side surface abut, make first hinged arm 41 unable relatively second hinged arm 42 positive rotation or reverse rotation, to keep the relative position between first hinged arm 41 and second hinged arm 42, and because second hinged arm 42 is fixed on first assembly component 10 through positioning clamping mechanism 122, so that first hinged arm 41 can also be stably fixed on first assembly component 10. Thus, by setting second positioning block 124, can be based on first positioning block 123, enhance the fixing effect of first positioning assembly 12 to first hinged arm 41, to prevent first hinged arm 41 sway influence the installation accuracy of hinge 40.

[0049] In one specific example, the first positioning pin 1222 is provided with two pins arranged in the front-rear direction, the second hinge arm 42 is provided with two second assembly holes 421 arranged in the front-rear direction, the second assembly hole 421 is used to connect with the upper end of the back door 30, such as a bolt is used to pass through the second assembly hole 421 and the upper end of the back door 30 and is tightened, when the hinge 40 is installed on the first assembly component 10, the two first positioning pins 1222 are respectively inserted into the two second assembly holes 421, that is, the second assembly hole 421 on the second hinge arm 42 is used for positioning cooperation. Among them, one of the two first positioning pins 1222 is a rhombus in cross section, and the other of the two first positioning pins 1222 is a circle in cross section, so that the two first positioning pins 1222 can better adapt to the machining tolerance of the two second assembly holes 421, so that the two first positioning pins 1222 can be smoothly inserted into the two second assembly holes 421. In addition, the second positioning block 124 is provided with two on the left and right sides of the positioning clamping mechanism 122, the first hinge arm 41 includes a hinge arm body 412 and two connecting ears 413, the second hinge arm 42 is rotatably connected with the hinge arm body 412, the upper surface of the hinge arm body 412 constitutes a cooperating positioning surface 414 which abuts against the first positioning surface, the two connecting ears 413 are respectively connected on the left and right sides of the rear end of the hinge arm body 412, the first assembly hole 411 is formed in the connecting ear 413 and penetrates through the front-rear direction, the heights of the first assembly holes 411 on the two connecting ears 413 are different, such as the left first assembly hole 411 is located at the lower part of the connecting ear 413, and the right first assembly hole 411 is located at the upper part of the connecting ear 413, the second positioning surface of the left second positioning block 124 abuts against the rear side surface of the left connecting ear 413 and is arranged in the up-down direction with the first assembly hole 411, and the second positioning surface of the right second positioning block 124 abuts against the rear side surface of the right connecting ear 413 and is arranged in the up-down direction with the first assembly hole 411, so that the two second positioning blocks 124 avoid the assembly avoiding space 121, and the connection between the first hinge arm 41 and the vehicle body 50 is facilitated.

[0050] According to some embodiments of the present application, as shown in Figures 4 to 6 The second positioning component 13 includes a second positioning pin 131 and a plurality of fixed clamping mechanisms 132, the plurality of fixed clamping mechanisms 132 are distributed on the front and rear sides of the second positioning pin 131, the second positioning pin 131 extends in the up-down direction and is suitable for plug-in cooperation with the vehicle body 50, and the fixed clamping mechanism 132 is used for clamping or releasing the vehicle body 50. Among them, the first assembly component 10 is positioned on the vehicle body 50 through the plug-in cooperation of the second positioning pin 131, that is, the position of the second positioning pin 131 is the positioning position of the first assembly component 10, and the first assembly component 10 is fixedly connected with the vehicle body 50 through the fixed clamping mechanism 132, that is, the position of the fixed clamping mechanism 132 is the fixed position of the first assembly component 10.

Through the cooperation of the two second positioning pins 131 and the vehicle body 50, the freedom of movement of the first assembly component 10 relative to the vehicle body 50 in the left and right direction and the front and rear direction can be better limited.

[0053] In addition, the fixed clamping mechanism 132 comprises a second clamping block 1321 and a second clamping unit 1322, the bottom surface of the second clamping block 1321 constitutes a clamping surface, the second clamping unit 1322 is located at the lower side of the second clamping block 1321, the second clamping unit 1322 has a second clamping position and a second avoiding position, in the second clamping position, the second clamping unit 1322 cooperates with the second clamping block 1321 to define a second clamping space for clamping the vehicle body 50, at this time, the clamping surface of the second clamping block 1321 abuts against the upper surface of the vehicle body 50, the second clamping unit 1322 contacts the lower surface of the vehicle body 50 from the lower side of the vehicle body 50, so that the vehicle body 50 is clamped from the upper and lower sides by the second clamping unit 1322 and the second clamping block 1321, and the movement freedom of the first assembly component 10 relative to the vehicle body 50 in the up-down direction can be better limited; in the second avoiding position, the second clamping unit 1322 moves towards the front side or the rear side of the vehicle body 50, for example, the fixed clamping mechanism 132 installed at the front end of the first tooling body 11 is a first fixed clamping mechanism 132a, and the fixed clamping mechanism 132 installed at the rear end of the first tooling body 11 is a second fixed clamping mechanism 132b, in the second avoiding position, the second clamping unit 1322 of the first fixed clamping mechanism 132a is located at the front side of the second clamping block 1321, and the second clamping unit 1322 of the second fixed clamping mechanism 132b is located at the rear side of the second clamping block 1321, so as to prevent the second clamping unit 1322 from interfering with the installation and disassembly of the first assembly component 10 relative to the vehicle body 50 in the up-down direction.
