The method specifically comprises the following steps: the entire semi-finished door is immersed in the electrophoretic fluid for a predetermined time so that the bonding portion 221 is heated to be foamed, the inner side of the bonding portion 221 is bonded to the outer side of the inner panel 20, and the outer side of the bonding portion 221 is bonded to the inner side of the reinforcement main body portion 220. This allows the adhesive portion 221 to be foamed and expanded so as to be extremely firmly adhered between the outer side 201 of the inner panel 20 and the groove of the inner side of the reinforcement main body portion 220, thereby improving the structural strength thereof.

And 103, cooling the semi-finished vehicle door subjected to the electrophoresis treatment to enable the bonding part 221 to be in a solid state, so as to obtain the vehicle door 2. In this embodiment, after the electrophoresis treatment is completed, the semi-finished door after the electrophoresis treatment is taken out from the electrophoresis liquid and cooled, so that the bonding portion is more firmly bonded between the outer side 201 of the inner panel 20 and the groove of the inner side of the reinforcement main body portion 220.

Preferably, the predetermined time is 20 minutes to 30 minutes, and the temperature in the electrophoretic fluid is maintained at 165 ℃ to 185 ℃. This enables the adhesive portion to be sufficiently foamed and adhered to the outer side surface of the inner panel, and ensures the material properties of the adhesive portion. Further preferably, the predetermined time is 20 minutes and the temperature in the electrophoretic fluid is maintained at 165 ℃. When the temperature in the electrophoresis liquid reaches 165 ℃, the bonding part (such as the compound adhesive) is in a foaming shape, and within 20 minutes of heat preservation, the foaming bonding part is filled between the inner side surface of the reinforced main body part and the outer side surface of the inner plate, and the foaming adhesive is adhered to the inner plate, so that the viscosity of the bonding part is further enhanced, and the structural strength of the matched part of the reinforced main body part, the inner plate and the outer plate is further improved. Of course, it will be appreciated by those skilled in the art that the predetermined time and the temperature of the electrophoresis process are not limited to the above description, and do not limit the scope of the present invention.

While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the principles and spirit of the invention, but such changes and modifications fall within the scope of the invention.
