[0002] In the existing assembly process, door modules and body modules are connected by fasteners such as screws. On the assembly site, there is a risk of human error causing the door module to disconnect from the body module and fall off.

[0073] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0075] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0076] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0077] See Figures 1 to 3 This embodiment provides an assembly device 100 for assembling a door module 200 and a body module 300. Both the door module 200 and the body module 300 can be configured as car models for simulated assembly applications before actual production. In other embodiments, the door module 200 and the body module 300 can also be configured as actual vehicle structures being assembled.

[0078] The body module 300 has two mounting positions P for mounting the front door module 200 and the rear door module 200 of the vehicle, respectively. The assembly equipment 100 includes a support device 20, a mounting assembly 30, a guide rail assembly 40, and a limiting device 10. The support device 20 carries the door module 200 and can specifically be configured as a transport trolley to transport the door module 200 to different mounting positions P on the body module 300.

[0079] The guide rail assembly 40 is mounted on the support device 20, and the mounting assembly 30 is slidably mounted on the guide rail assembly 40. The mounting assembly 30 is used to connect the door module 200 and can drive the door module 200 to move along the guide rail assembly 40, thereby accurately moving the door module 200 to the mounting position P of the body module 300 to ensure the assembly accuracy of the door module 200 and the body module 300. Two guide rail assemblies 40 can be provided, and one end of the guide rail assembly 40 extends beyond the support device 20 to facilitate the transport of the door module 200 to the body module 300 when the support device 20 and the body module 300 are spaced apart.

[0080] Mounting assembly 30 includes a base plate 31 and a mounting frame 32. The base plate 31 is slidably mounted on the guide rail assembly 40. The mounting frame 32 includes two side beams 321 and multiple cross beams 322. The two side beams 321 extend vertically and are spaced apart. One side beam 321 is connected to the base plate 31. The multiple cross beams 322 are spaced apart vertically and are respectively connected between two side beams 321.

[0081] See Figure 3The limiting device 10 includes features to prevent the door module 200 from falling relative to the body module 300. The door module 200 is configured to be disposed on the support device 20. The limiting device 10 includes a first limiting member 11 and a second limiting member 12. The first limiting member 11 is used to connect one of the door module 200 and the body module 300, and is used to engage with the other of the door module 200 and the body module 300. The second limiting member 12 is configured to connect one of the support device 20 and the door module 200, and is used to engage with the other of the support device 20 and the door module 200.

[0082] According to the limiting device 10 of this application, the first limiting member 11 can effectively prevent the door module 200 from falling relative to the body module 300, and the second limiting member 12 can effectively prevent the door module 200 from falling relative to the support device 20. Thus, during the assembly process of the door module 200 and the body module 300, even if the operator unlocks the door module 200 from the body module 300 or the support device 20, the door module 200 can still remain relatively fixed to the body module 300, so that the position of the door module 200 remains stable and reliable, reducing the problem of the door module 200 falling and being damaged due to misoperation, thereby avoiding potential maintenance costs and safety hazards, and improving vehicle assembly efficiency.

[0083] Furthermore, compared to the methods used in known technologies, such as setting up warning signs or assigning dedicated personnel to handle the problem of the door module 200 falling, the use of the limiting device 10 of this application eliminates the need for on-site operators to specifically manage the door module 200, thereby reducing the workload of operators and improving their time utilization.

[0084] In some embodiments, see Figures 4 to 8 The first limiting member 11 is connected to the door module 200. The limiting device 10 also includes a third limiting member 13, which is configured to be connected to the body module 300. The third limiting member 13 has a first through hole K1, and the first limiting member 11 passes through the first through hole K1. The first limiting member 11 is configured to cooperate with the third limiting member 13 to limit the movement of the door module 200 relative to the body module 300.

[0085] Thus, the installation of the first limiting component 11 and the third limiting component 13 is relatively convenient. The first limiting component 11 and the third limiting component 13 can be quickly installed on the existing body module 300 and door module 200, thereby reducing the modification cost.

[0086] In other embodiments, the first limiting member 11 can also be connected to the body module 300, and the third limiting member 13 can be connected to the door module 200, which can also achieve the function of limiting the door module 200 to the body module 300.

[0087] In some embodiments, the first limiting member 11 and the third limiting member 13 are both made of high-strength materials such as steel. The known body module 300 or door module 200 are made of materials with low strength. In this way, compared with the first limiting member 11 directly cooperating with the body module 300, the problem that the body module 300 is too weak to support the first limiting member 11 can be avoided, thereby ensuring that the third limiting member 13 can limit the first limiting member 11 and ensure that the door module 200 will not fall off the body module 300.

[0088] In some embodiments, see Figure 3 and Figure 4 The door module 200 includes a module body 201 and a hinge assembly 202. The hinge assembly 202 is connected to one side of the module body 201 and is configured to connect to the body module 300, so that the door module 200 can be rotatably connected to the body module 300. One end of the first limiting member 11 is connected to the hinge assembly 202, and the other end of the first limiting member 11 passes through the third limiting member 13. In this way, the connection structure between the door module 200 and the body module 300 can be better utilized, the installation environment of the first limiting member 11 can be further strengthened, the connection between the first limiting member 11 and the door module 200 can be made more reliable, the possibility of the first limiting member 11 falling off the door module 200 can be reduced, and thus the anti-fall-off effect can be further improved.

[0089] In some embodiments, there are two first limiting members 11 and two third limiting members 13. There are two hinge assemblies 202. The two first limiting members 11 are respectively connected to the two hinge assemblies 202. The body module 300 includes an A-pillar model 301 and a B-pillar model 302. Two third limiting members 13 are spaced apart on the A-pillar model 301. Two other third limiting members 13 are spaced apart and connected to the B-pillar model 302. In other embodiments, the number of first limiting members 11 may also be one, three, or more. The number of third limiting members 13 on the A-pillar model 301 or the B-pillar model 302 may also be one, three, or more.

[0090] In some embodiments, see Figures 5 to 7The first limiting member 11 has a first limiting groove C1 on its periphery, and the third limiting member 13 has a first limiting flange 131 protruding from the hole surface near the first through hole K1. The first limiting flange 131 has a first limiting hole K3. The first limiting member 11 is movably inserted into the first limiting hole K3 along the radial direction of the first limiting hole K3. When the door module 200 drives the first limiting member 11 to move downward away from the third limiting member 13, the first limiting flange 131 extends into the first limiting groove C1 to limit the first limiting member 11 to the third limiting member 13. Thus, when the connection between the door module 200 and the body module 300 is broken, as the door module 200 tilts downward relative to the body module 300 under the action of gravity, the downward side of the first limiting groove C1 approaches the first limiting flange 131 until the first limiting flange 131 extends into the first limiting groove C1, thereby preventing the first limiting member 11 from continuing to move relative to the third limiting member 13, so as to limit the door module 200 from moving relative to the body module 300.

[0091] Furthermore, during the debugging process of the door module 200, it is necessary to disassemble or assemble the door module 200 from the body module 300 multiple times. When the radial direction of the first limiting member 11 is approximately parallel to the radial direction of the first limiting hole K3, the door module 200 can be quickly installed on the body module 300 or removed from the body module 300. Thus, the first limiting member 11 in this embodiment can ensure efficient disassembly and assembly between the door module 200 and the body module 300 multiple times while ensuring the function of preventing falling, thereby improving the convenience of operation.

[0092] Specifically, in this embodiment, there is a first gap between the outer peripheral surface of the first limiting member 11 and the first through hole K1, and the size of the first gap is between 0.3mm and 0.7mm. For example, the first gap can be set to one of 0.3mm, 0.4mm, 0.5mm, 0.6mm, and 0.7mm. If the first gap is too small, the first limiting member 11 is prone to jamming with the third limiting member 13; if the first gap is too large, it is not conducive to the limiting cooperation between the first limiting flange 131 and the first limiting groove C1. By setting the first gap between 0.3mm and 0.7mm, it can be ensured that the door module 200 can be separated from the body module 300 quickly and efficiently, and it can also be ensured that the door module 200 will not fall off the body module 300 in case of an accident.

[0093] In other embodiments, a limiting block can also be provided at the end of the third limiting member 13 opposite to the first limiting member 11, where the first limiting member 11 is located. The diameter of the limiting block is larger than the diameter of the first limiting hole K3 and the diameter of the limiting block is larger than the diameter of the first through hole K1. In this way, by the limiting block abutting against the third limiting member 13, the first limiting member 11 can also prevent the third limiting member 13 from disengaging. In addition, the first limiting member 11 can also be constructed as a knob structure, which is rotatably connected to the door module 200. The knob structure can be set to a first position and a second position. When the knob structure is in the first position, it can disengage from the first through hole K1. When the knob structure is in the second position, it can abut against the third limiting member 13. In this way, the first limiting member 11 can also be efficiently switched between the limiting state and the disengaging state.

[0094] In some embodiments, see Figure 5 The first limiting flange 131 protrudes from the hole surface of the first limiting hole K3 near the end of the first limiting member 11. In other embodiments, the first limiting flange 131 may also protrude from the hole surface of the first limiting hole K3 away from the end of the first limiting member 11, or protrude from the middle portion of the first limiting hole K3.

[0095] In another embodiment, the first limiting member 11 is configured to connect to the door module 200. The first limiting member 11 has a first limiting portion, and the body module 300 has a second limiting portion. The first limiting portion is configured to cooperate with the second limiting portion to limit the movement of the door module 200 relative to the body module 300. The shape of the first limiting portion is the same as the shape of the first limiting groove C1, and the shape of the second limiting portion is the same as the shape of the first through hole K1, the first limiting hole K3, and the first limiting flange 131.

[0096] In some embodiments, see Figure 5 The body module 300 has a first clearance hole K5 on the side near the door module 200, and the first clearance hole K5 is connected to the first through hole K1. When the door module 200 and the body module 300 are connected, the first limiting groove C1 is located on the side of the third limiting member 13 away from the first limiting member 11, and a part of the first limiting groove C1 is located in the first clearance hole K5, and the other part is located in the first through hole K1.

[0097] In some embodiments, see Figure 8 The limiting device 10 also includes a first fastener 15, which is fixedly connected between the hinge assembly 202 of the door module 200 and the third limiting member 13. This further improves the connection reliability between the door module 200 and the body module 300.

[0098] In some embodiments, see Figure 9 and Figure 10The second limiting member 12 is configured to be connected to the supporting device 20. In this embodiment, the second limiting member 12 is connected to the supporting device 20 via the side beam 321 of the mounting frame 32 of the mounting assembly 30. The limiting device 10 also includes a fourth limiting member 14, which is configured to be connected to the door module 200. The fourth limiting member 14 has a second through hole K2, through which the second limiting member 12 passes. The second limiting member 12 is configured to cooperate with the fourth limiting member 14 to limit the movement of the door module 200 relative to the supporting device 20. Thus, the installation of the second limiting member 12 and the fourth limiting member 14 is relatively convenient, and the second limiting member 12 and the fourth limiting member 14 can be quickly installed on the existing supporting device 20 and door module 200, thereby reducing the modification cost.

[0099] In other embodiments, the second limiting member 12 can also be connected to the door module 200, and the fourth limiting member 14 can be connected to the mounting component 30 of the carrier device 20, which can also achieve the function of limiting the door module 200 to the carrier device 20.

[0100] In some embodiments, the second limiting member 12 and the fourth limiting member 14 are both made of high-strength materials such as steel. The known load-bearing device 20 or door module 200 are made of materials with low strength. In this way, compared with the second limiting member 12 directly cooperating with the door module 200, the problem of the door module 200 being too weak to support the second limiting member 12 can be avoided, thereby ensuring that the fourth limiting member 14 can limit the second limiting member 12 and ensure that the door module 200 will not fall off the load-bearing device 20.

[0101] In some implementations, see Figure 2 The number of second limiting members 12 and the number of fourth limiting members 14 are both four. The four second limiting members 12 are disposed on the mounting assembly 30 and located at the four corners of the rectangle. The four fourth limiting members 14 are disposed at the four corners of the door module 200. In other embodiments, the number and arrangement of the second limiting members 12 and the number and arrangement of the fourth limiting members 14 can also be adjusted according to actual needs.

[0102] In some embodiments, see Figure 9 and Figure 10The second limiting member 12 has a second limiting groove C2 on its periphery. The fourth limiting member 14 has a second limiting flange 141 protruding from its hole surface near the second through hole K2. The second limiting flange 141 has a second limiting hole K4. The second limiting member 12 is movably inserted into the second limiting hole K4 along the radial direction of the second limiting hole K4. During the process of the door module 200 driving the second limiting member 12 to move downward away from the fourth limiting member 14, the second limiting flange 141 extends into the second limiting groove C2 to limit the second limiting member 12 to the fourth limiting member 14. Thus, when the connection between the door module 200 and the support device 20 is broken, and the door module 200 tilts downward relative to the mounting assembly 30 under the action of gravity, the second limiting flange 141 of the fourth limiting member 14 moves downward and extends into the upward side of the second limiting groove C2, thereby limiting the fourth limiting member 14 to continue moving relative to the second limiting member 12, so as to limit the door module 200 to move relative to the mounting assembly 30.

[0103] Furthermore, during the debugging process of the door module 200, the self-supporting device 20 of the door module 200 needs to be disassembled or assembled multiple times. When the radial direction of the second limiting member 12 is approximately parallel to the radial direction of the second limiting hole K4, the door module 200 can be quickly installed on the supporting device 20 or the self-supporting device 20 can be removed. Thus, the second limiting member 12 in this embodiment can ensure the efficient disassembly and assembly of the door module 200 and the supporting device 20 multiple times while ensuring the function of preventing falling, thereby improving the convenience of operation.

[0104] Specifically, in this embodiment, a second gap exists between the outer peripheral surface of the second limiting member 12 and the second through hole K2, and the size of the second gap ranges from 0.3mm to 0.7mm. For example, the second gap can be set to one of 0.3mm, 0.4mm, 0.5mm, 0.6mm, and 0.7mm. If the second gap is too small, the second limiting member 12 is prone to jamming with the fourth limiting member 14; if the second gap is too large, it is not conducive to the limiting fit between the second limiting flange 141 and the second limiting groove C2. By setting the second gap between 0.3mm and 0.7mm, it is possible to ensure that the door module 200 can be separated from the support device 20 quickly and efficiently, and it is also possible to ensure that the door module 200 will not fall off the support device 20 in case of an accident.

[0105] In other embodiments, a limiting block can also be provided at the end of the second limiting member 12 located away from the fourth limiting member 14. The diameter of the limiting block is larger than the diameter of the second limiting hole K4 and the diameter of the limiting block is larger than the diameter of the second through hole K2. In this way, by the limiting block abutting against the fourth limiting member 14, the second limiting member 12 can also prevent the fourth limiting member 14 from disengaging. In addition, the second limiting member 12 can also be constructed as a knob structure, which is rotatably connected to the door module 200. The knob structure can be set to a first position and a second position. When the knob structure is in the first position, it can disengage from the second through hole K2. When the knob structure is in the second position, it can abut against the fourth limiting member 14. In this way, the second limiting member 12 can also be efficiently switched between the limiting state and the disengaged state.

[0106] In some embodiments, see Figure 9 and Figure 10 The second limiting flange 141 protrudes from the hole surface of the second limiting hole K4 near the end of the second limiting member 12. In other embodiments, the second limiting flange 141 may also protrude from the hole surface of the second limiting hole K4 away from the end of the fourth limiting member 14, or protrude from the middle portion of the first limiting hole K3.

[0107] In another embodiment, the second limiting member 12 is configured to be connected to the support device 20. The second limiting member 12 has a third limiting portion, and the door module 200 has a fourth limiting portion. The third limiting portion is configured to cooperate with the fourth limiting portion to limit the movement of the door module 200 relative to the support device 20. The shape of the third limiting portion is the same as that of the second limiting groove C2, and the shape of the fourth limiting portion is the same as that of the second through hole K2, the second limiting hole K4, and the second limiting flange 141.

[0108] In some embodiments, the second limiting member 12 includes a mounting portion 121 and a limiting pin 122. The mounting portion 121 is configured to be connected to the support device 20, specifically to the mounting assembly 30 on the support device 20. A second fastener 16 passes through the mounting portion 121 and is connected to the door module 200. One end of the limiting pin 122 is connected to the mounting portion 121, and the other end is movably inserted through the second through hole K2.

[0109] In some embodiments, see Figure 9 and Figure 10 The limiting device 10 also includes a second fastener 16, which is fixedly connected between the second limiting member 12 and the fourth limiting member 14. This further improves the connection reliability between the door module 200 and the mounting assembly 30. Furthermore, the second fastener 16 and the limiting pin 122 can be spaced apart horizontally or vertically.

[0110] In some embodiments, see Figure 9 and Figure 10 The mounting section 121 includes a first plate segment 1211 and a second plate segment 1212. The first plate segment 1211 is connected to the side beam 321 of the mounting assembly 30. The second plate segment 1212 is bent and connected to the first plate segment 1211, and extends in a direction away from the mounting assembly 30. The second plate segment 1212 corresponds to and is parallel to the plate surface of the fourth limiting member 14. A limiting pin 122 is connected to the second plate segment 1212. In this way, it is convenient to install the limiting pin 122 and the second fastener 16 on the second plate segment 1212, and it is convenient to fit with the fourth limiting member 14, thereby ensuring that the surface difference between the door module 200 and the body module 300 is small.

[0111] In some embodiments, see Figure 9 and Figure 10 The door module 200 has a second clearance hole K6 on the side near the fourth limiting member 14, and the second clearance hole K6 communicates with the second through hole K2. When the door module 200 is connected to the mounting assembly 30, the second limiting groove C2 is located at the end of the limiting pin 122 away from the mounting part 121, and a part of the second limiting groove C2 is located in the second clearance hole K6, and the other part is located in the second through hole K2.

Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
