The total number of doors including the trunk door on the car body. As a sign of the use of automobiles, the cars of business use are four doors. There are both four doors and three and five doors (back doors), while sports cars used for sports use are two doors. The number of doors calculated here includes the backup door.
Car door types:
1. Overall door
We encountered the most door doors in our work. This kind of door is easy to disassemble, and you can work with just unloading the door of the door. However, the internal structure of the door is complicated, and there are many related parts, such as lifts, door -controlled motors, door lock connectors, wire beams, etc. When the door sheet metal is maintained, the space is small, which is not conducive to the entry of tools, and it is very inconvenient to operate.
2. Divided doors
The most representative door of the split -type car is the door of the red flag passenger car. The panel of this door is separated from the inner skeleton. During maintenance,

2. Divided doors
The most representative door of the split -type car is the door of the red flag passenger car. The panel of this door is separated from the inner skeleton. During maintenance, the interior board and inner skeleton need to be removed during maintenance. This form of doors are very beneficial to sheet metal maintenance and have enough space to use, but it is more troublesome to repair and replace the maintenance and replacement of other parts (glass lifts, door locks, etc.). In addition, each time the upper frame is disassembled, it must be adjusted repeatedly to ensure that the position of the adjacent components is correct, otherwise it will affect the easily and sealing performance of the door switch.
3. Golf passenger car door
The door of the golf passenger car absorbed the advantages of the above two doors (Figure 3). All attachments are installed on the overall lift, lifts and door locks are installed on a high -intensity aluminum alloy board (Figure 4), and then fixed on the door with bolts to improve the overall strength of the door, but also improve the door door. The sealing performance, but the disassembly is more troublesome, which is not conducive to the work of small sheet metal (small sheet metal: generally refers to the sheet metal work that is small and easier to repair).
4. Sagitar passenger car door
The door of Sagitar passenger car is based on the golf passenger car door A new improvement has been made. In the case of not disassembling the interior of the door, you can remove the door panel to perform the sheet metal repair and replace the parts of the door. Because this sealing strip is connected to the plastic buckle, the force should be gently during disassembly to prevent damage. Then disassemble the handle of the door. First hold the external handle to make it open (this is very critical. This disassembly method adheres to the traditional way of disassembling the public car door handlers of Volkswagen), loosen the fixed screw After removing the fixed block, separate the connection between the outer line of the door lock and the outside door handle, remove the outer door, remove the door handle fixing screwEssenceFinally, remove the fixed screws of the fixed door panel.
