[0035] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0036] As introduced in the background, when the side wall is a plastic part, the existing charging port cover is installed with the inner panel of the vehicle body, and after the cover is opened, the problem of bolt leakage occurs. Due to the certain deviation of the vehicle body and the deformation of the plastic side wall, the problem of poor matching between the charging port cover and the side wall also occurs, which seriously affects the sensory quality of the vehicle. In order to solve the above technical problems, the present application proposes a plastic side wall charging port cover assembly and a mounting method.

[0037] Example 1

[0038] In a typical embodiment of the present application, as shown in Figures 1-9 a plastic side wall charging port cover assembly is proposed, which comprises a charging port cover assembly 1, a plastic side wall 2 and a high-voltage panel 6.

[0039] The plastic side wall 2 is provided with a groove for mounting the charging port cover assembly 1, and the charging port cover assembly 1 and the high-voltage panel 2 are arranged on the inner and outer sides of the plastic side wall 2, respectively. The groove and the charging port cover assembly 1 are connected by a self-tapping screw 3, the self-tapping screw 3 penetrates the side wall of the groove bottom and is connected with the base 5 of the charging port cover assembly 1, and the self-tapping screw 3 does not penetrate the base 5;

[0040] The base 5 is provided with bolt holes, and the base 5 is connected with the plastic side wall 2 and the high-voltage panel 6 in sequence through bolts 4. The bolt holes are provided with bolt plugs 7 for plugging the bolt holes to avoid the leakage of the bolts 4.

[0041] It can be understood that the plastic side wall 2 and the high-voltage panel 6 are provided with bolt holes matched with the base 5.

[0042] Specifically, the charging port cover assembly 1 is composed of a base 5 and an outer cover plate hinged to the base 5. The base 5 is installed in the groove of the plastic side wall 2, and the outer cover plate is flush with the surface of the plastic side wall 2 in the buckled state.

[0043] The back of the base 5 (i.e., the side close to the high-voltage panel 6) is fixedly provided with a plurality of first legs 51 and second legs 52. The first legs 51 and the second legs 52 are located at the corners of the base 5. Specifically, the back side wall of the base 5 protrudes outward to form the first legs 51. The first legs 51 are provided with bolt holes penetrating the back side wall of the base 5 for the installation of the bolts 4. The first legs 51 have a space for accommodating the bolts 4. The internal space size of the first legs 51 matches the bolt plug 7. The bolt plug 7 can be buckled at the opening of the first legs 51 to plug the internal space, thereby shielding the bolts 4 and avoiding the leakage of the bolts 4.

[0044] The second legs 52 are fixedly connected with the back outer wall of the base 5 in an injection molding integrated manner. The length of the second legs 52 is the same as that of the first legs 51. The self-tapping screw 3 penetrates the plastic side wall 2 and is connected with the second legs 52. The length of the self-tapping screw 3 is less than that of the second legs 52, so that the self-tapping screw 3 cannot penetrate the second legs 52 and thus cannot penetrate the base 5 to extend outward. While ensuring the fixed connection between the base 5 and the plastic side wall 2, the leakage of the self-tapping screw 3 is avoided.

[0045] Since the charging port cover assembly 1 is connected with the plastic side wall 2 through the self-tapping screw 3, the plastic side wall 2 and the charging port cover assembly 1 can be assembled in advance in the production workshop. The assembly speed is fast, and the charging port cover assembly 1 does not need to be connected with the vehicle body inner panel and is not affected by the body deviation. The gap and the surface difference between the plastic side wall 2 and the charging port cover assembly 1 are greatly ensured, and the overall vehicle sensory degree is improved.

[0046] The high-voltage panel 6 is attached to the bottom outer wall of the groove of the plastic side wall 2. The high-voltage panel 6 is connected with the plastic side wall 2 and the charging port cover assembly 1 through the bolts 4, which can improve the strength of the charging port cover assembly 1 installed on the plastic side wall 2 and effectively avoid the influence of the deformation of the plastic side wall 2 on the sensory degree.

[0047] The charging port cover assembly 1 in the embodiment is made of plastic material, which is used in combination with the plastic side wall 2, can reduce the number of molds, and reduce the production cost and the vehicle quality compared with the traditional sheet metal stamping forming.

[0048] Since the surface contact is easy to deform, the limiting ribs are arranged at the first leg 51 and the periphery of the bolt hole of the plastic side wall 2, and specifically as shown in the figure, the bottom of the first leg 51 is fixedly provided with at least one circle of first limiting ribs 8 along the periphery of the bolt hole, which can improve the strength of the bottom of the first leg 5, and on the other hand, can reduce the contact area of the bottom of the first leg 5 and the plastic side wall 2, has high adhesion, small deviation, and reduces the influence of the deformation of the outer trim panel of the plastic side wall 2 on the adhesion. Figure 7

[0049] It should be noted that the first limiting rib 8 should be flush with the first leg 5 to ensure that the outer cover plate is flush with the plastic side wall 2 after installation.

[0050] The back of the plastic side wall 2 is fixedly provided with at least one circle of second limiting ribs 9 along the periphery of the bolt hole, and the front of the high-pressure panel 6 is provided with a clamping groove matched with the second limiting rib 9, which can improve the strength of the plastic side wall 2 at the bolt hole, and on the other hand, can realize the rapid positioning of the plastic side wall 2 and the high-pressure panel 6, improve the consistency of the assembly, and avoid the loss of working hours and sample parts caused by secondary rework.

[0054] Then, the charging port cover assembly 1, the plastic side wall 2 and the high-pressure panel 6 fixed on the vehicle body are connected together by using the bolt 4;

[0055] The bolt plug 7 is buckled in the bolt hole of the charging port cover assembly 1 to shield the bolt 4 and avoid the leakage of the bolt 4.

[0056] Specifically, the charging port cover assembly 1 is assembled so that the outer cover plate is hinged to the base 5, the assembled charging port cover assembly 1 is placed in the groove of the plastic side wall 2, the bolt hole on the first leg 51 is coaxially arranged with the bolt hole on the plastic side wall, the base 5 and the plastic side wall 2 are fixedly connected together by using the self-tapping screw 3, the self-tapping screw 3 penetrates the side wall at the bottom of the groove of the plastic side wall 2 and is connected with the second leg 52, and the self-tapping screw 3 does not penetrate the second leg 52.

[0057] ​Then the assembled plastic side wall 2, charging port cover assembly 1 is connected with the high-voltage panel 6 as a whole, so that the second limiting rib 9 on the plastic side wall 2 is inserted into the clamping groove of the high-voltage panel 6, and the first leg 51 on the base 5 is fixedly connected with the plastic side wall 2 and the high-voltage panel 6 by the bolt 4;

[0058] Then the bolt plug 7 is buckled at the opening of the first leg 51 to shield the bolt 4, and the assembly of the plastic side wall charging port cover assembly is completed.
