[0002] Door assembly is one of the key steps in automobile manufacturing, ensuring the fit between the door and the body, which is crucial for maintaining the vehicle's aesthetics and ensuring body precision.

[0003] Currently, most automobile manufacturing workshops use built-in tooling to assemble car doors. This tooling is typically equipped with fixed locating pins that position the door during assembly, ensuring its relative position to the car body. The assembly consistency of vehicles in the same batch can be guaranteed through this fixed tooling, thus ensuring assembly quality to a certain extent.

[0004] While built-in tooling can provide consistency across the same batch of vehicles, it has significant limitations. While assembly consistency within the same batch can be guaranteed, the quality of parts can fluctuate between different batches. To address this, workers need to manually adjust the shims under the retaining pins to accommodate dimensional variations in parts from different batches, ensuring proper clearance between the door and the vehicle body.

[0005] Clearly, this process is not only time-consuming and labor-intensive, significantly reducing assembly efficiency, but also increases production costs due to frequent adjustments and rework, affecting overall vehicle quality and delivery time. Utility Model Content

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0038] The following is combined with Figures 1-9 A preferred embodiment of the present invention is described: a car door assembly device.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The door assembly device provided in this embodiment is used to assist in assembling a door to a vehicle body, and includes: an assembly frame 3, a positioning component and at least one sliding positioning component.

[0040] The geometry of the assembly frame 3 is set according to the shape of the vehicle door, and may include multiple longitudinally and transversely connected frame edges; furthermore, multiple through holes may be provided on the frame edges. This structural design allows for weight reduction as much as possible while ensuring the strength of the assembly frame, thus reducing the burden of manual assembly. In specific implementations, the assembly frame 3 can be made of aluminum alloy brackets.

[0041] A positioning component is connected to the assembly frame 3 to fix the assembly frame 3 to the vehicle body. In this embodiment, the positioning component includes multiple positioning parts 2; each positioning part 2 is fixed to the outer perimeter of the assembly frame 3, preferably evenly distributed. Obviously, multiple positioning parts 2 enhance the fixation stability between the assembly frame and the vehicle body.

[0042] In this embodiment, the sliding positioning assembly includes a gap portion and a sliding positioning pin 1. The gap portion and the sliding positioning pin will be described in detail below.

[0043] The gap is a structure independent of the mounting frame 3 and is not fixed to the mounting frame 3. Its specific structure needs to be further referenced. Figure 4 and Figure 5 Let me explain further.

[0044] In this embodiment, the gap portion 6 includes a base plate 61 and a gap block 62; the gap block 62 is fixedly connected to the base plate 61; the width of the gap block 62 along the direction of the base plate is set according to a predetermined gap, which is the distance between the door and the side panel of the vehicle body, thereby ensuring that the working width of the gap portion 6 is the predetermined gap between the door and the side panel of the vehicle body. During assembly, the gap portion is located in the edge area adjacent to the outer panel of the door, preferably in the area adjacent to the door lock.

[0045] More preferably, in this embodiment, the gap portion 6 further includes a magnetic snap fastener 63; the magnetic snap fastener 63 is disposed on the base plate 61; the gap portion 6 is fixed to the outer panel of the door by the magnetic snap fastener. The use of the magnetic snap fastener simplifies the installation process of the gap portion and improves assembly efficiency.

[0046] It can be seen that the purpose of the structural features of the gap 6 described above is to facilitate the positioning of the gap.

[0047] Reference Figure 6 and Figure 7 This illustrates one positioning and installation method for the gap 6.

[0048] When using the door assembly device of this embodiment for auxiliary assembly of the door, the gap portion 6 can be installed on the outer panel of the door. More specifically, in Figure 6 In the illustrated embodiment, a front door 9, a rear door 10, and a gap 6 are shown. The gap 6 is positioned with the rear door 10 as a guide for mounting the front door 9. (See reference...) Figure 7 The bottom plate 61 of the gap section 6 is attached to the outer panel of the door by means of magnetic snaps, etc., and the gap section 62 of the gap section 6 is inserted into the gap between the front door 9 and the side wall of the vehicle body.

[0049] Below, refer to Figure 8 and Figure 9 The second key structure in the sliding positioning component, the sliding positioning pin 1, will be explained.

[0050] The sliding positioning pin 1 is fixedly connected to the assembly frame 3. The sliding positioning pin 1 is used to slide and adjust the position of the door until it contacts the gap 6, and to fix the door to the assembly frame 3.

[0051] In this embodiment, two sets of sliding positioning components are included. There are two sets of sliding positioning pins 1 in these two sets of sliding positioning components, which are symmetrically arranged on the assembly frame 3, for example, the left side frame and the right side frame of the assembly frame 3.

[0052] More specifically, in this embodiment, the sliding positioning pin 1 includes a pin body 11, a sliding mechanism 12, and a locking mechanism 13; the pin body 11 is connected to the sliding mechanism; the locking mechanism 13 is used to fix the pin body 11 when the pin body 11 reaches the desired position.

[0053] During assembly, the sliding locating pin, in cooperation with the sliding mechanism, adjusts its fixed position and, together with the locking mechanism 13, fixes the pin 11 in a specific position, ensuring that the door will not move when locked, thus guaranteeing the accuracy of the door's position. It can be seen that the pin 11, the sliding mechanism 12, and the locking mechanism 13 work together to allow the door to move on the assembly frame. By adjusting their positions, the door contacts the gap block 62, thereby achieving the predetermined gap.

[0054] This embodiment also includes a locking mechanism 8. The locking mechanism 8 is used to lock the door to the assembly frame 3, thereby improving the stability of the door during assembly.

[0055] Furthermore, in this embodiment, the sliding positioning assembly also includes a transition portion 4; the transition portion 4 is fixed to the assembly frame 3, and the transition portion 4 is used to adjust the position of the sliding positioning pin 1 in a first direction and / or a second direction by adjusting the thickness of the shim 5; wherein, the first direction is the sliding direction of the sliding positioning pin 1, and the second direction is a vertical direction perpendicular to the first direction. More specifically, the transition portion 4 may include a first connector and a second connector; the first connector is perpendicular to the second connector; and the first connector and the second connector are integrally formed.

[0056] In this embodiment, the adapter, as part of the sliding positioning assembly, is fixed to the assembly frame, providing additional adjustment directions. This allows the sliding positioning pin to be finely adjusted in two orthogonal directions via the shims of the adapter. This bidirectional adjustment capability enables the assembly device to more accurately adapt to the relative position between the door and the vehicle body, reducing assembly errors.

[0057] When assembling a vehicle door using the door assembly device provided in this embodiment, the following steps are included:

[0058] Step 1: Assemble the frame as the main structure and fix it to the vehicle body using positioning components;

[0059] Step 2: Install the gap portion of the sliding positioning assembly onto the outer panel of the door to be installed;

[0060] Step 3: Slide the door to be installed onto the gap block using the sliding positioning pin; if necessary, allow the sliding positioning pin to be finely adjusted in both directions based on the shim of the adapter 4.

[0061] Step 4: Lock the car door using a locking mechanism;

[0062] Step 5, install door bolts 7;

[0063] Step 6: After the car door is installed, remove the gap block, loosen the sliding positioning pin and locking mechanism 8, open the car door, and remove the assembly frame and other tooling.

[0064] After performing the above 6 steps, the door assembly is complete.

[0065] As can be seen, this embodiment sets a sliding positioning component, which includes a gap block and a sliding positioning pin, on the assembly frame. By using the gap block as a reference, and setting its width to the preset gap between the door and the side wall of the vehicle body, the position adjustment function and positioning function of the sliding positioning pin are used to precisely control the gap between the door and the vehicle body after assembly, thereby ensuring the aesthetics of the vehicle body and the assembly accuracy.

[0066] Clearly, in the above operation, when there are fluctuations in the parts between different batches, there is no need to adjust the tooling. This tooling can be used directly for assembly, ensuring assembly accuracy and stability and improving assembly efficiency.

[0067] In other words, the door assembly device of this utility model eliminates the need for workers to manually adjust operations such as shims under the fixing pins to adapt to the size changes of different batches of parts. As a result, compared with the existing built-in door assembly process using fixing pins, the assembly efficiency is significantly improved. Consequently, since frequent adjustments and rework are not required, production costs are increased, the overall vehicle quality is improved, and the delivery time is shortened.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
