Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing technology, specifically referring to a plastic charging port cover. Background Technology

[0002] like Figure 1 As shown, most new energy vehicles currently have plastic charging port covers, typically located on the rear side panel. These covers generally consist of an outer panel and a charging port box assembly. The charging socket is installed on the outer wheel arch panel through a perforation, while the charging port cover is installed on the side panel. The charging socket head protrudes from a soft rubber opening inside the charging port box assembly. There is space between the side panel and the outer wheel arch panel leading to the vehicle's interior, thus requiring a high level of sealing for the charging port cover. To address this, a soft rubber interference fit is typically used at the joint between the charging port box assembly and the side panel's flange to form a sealing surface, with no direct contact with the secondary flange of the side panel. This solution is structurally simple, but the soft rubber fit is prone to wrinkles and warping, allowing rainwater to seep into the interior through these poor fits during rain. Utility Model Content

[0003] In order to overcome some of the problems mentioned in the background above, this utility model provides a plastic charging port cover to at least partially solve the above problems.

[0004] According to the technical solution of this utility model, a plastic charging port cover is provided, including a charging port cover, a charging port side panel, and a charging port housing. The charging port cover is connected to the charging port housing. The charging port side panel includes a side panel outer plate, a first flange, a second flange, and a third flange. The charging port side panel and the charging port housing are connected by soft rubber. The soft rubber interferes with the soft rubber of the first flange and the third flange, respectively.

[0005] Preferably, the charging port side panel further includes a first bending portion, a connecting bending portion, and a tail bending portion. The two ends of the first bending portion are respectively connected to the outer side panel and a flange. The two ends of the connecting bending portion are respectively connected to a flange and a secondary flange or to two adjacent secondary flanges. The two ends of the tail bending portion are respectively connected to a secondary flange and a tail flange. The end of the tail flange away from the tail bending portion extends towards the charging port housing.

[0006] Preferably, the soft adhesive includes a first sealing edge, a connecting portion, and a second sealing edge. The first sealing edge is interference-connected with a flange, and the second sealing edge is interference-connected with a tail flange. The connecting portion is disposed between the charging port side panel and the charging port housing.

[0007] Preferably, the first sealing edge interference extends away from the charging port housing through a flange, and the second sealing edge interference extends away from the charging port housing through the tail flange.

[0008] Preferably, the side panel, the first flange, the second flange, the last flange, the first bend, the connecting bend, and the last bend are integrally formed.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This utility model improves sealing performance by turning two flanges at the opening of the side panel and then turning a small flange outward. The charging port housing is surrounded by a ring of injection-molded soft rubber, and both sides of the soft rubber are designed with sealing edges that interfere with the flanges of the side panel to form two seals. This effectively prevents rainwater from seeping into the gap between the side panel sheet metal and the soft rubber of the charging port cover. Attached Figure Description

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0017] like Figure 2 and Figure 3 As shown, this utility model embodiment provides a plastic charging port cover, including a charging port cover 1, a charging port side panel, and a charging port housing 3. The charging port cover 1 is connected to the charging port housing 3. The charging port side panel includes a side panel outer plate 21, a first flange 22, a second flange 23, and a last flange 24. The charging port side panel and the charging port housing 3 are connected by soft rubber. The soft rubber interferes with the soft rubber of the first flange 22 and the last flange 24 respectively.

[0018] In a further embodiment of this example, the charging port side panel further includes a first bending portion 25, a connecting bending portion 26, and a tail bending portion 27. The two ends of the first bending portion 25 are respectively connected to the outer side panel 21 and a first flange 22. The two ends of the connecting bending portion 26 are respectively connected to the first flange 22 and a secondary flange 23 or to two adjacent secondary flanges 23. The two ends of the tail bending portion 27 are respectively connected to the secondary flange 23 and the tail flange 24. The end of the tail flange 24 away from the tail bending portion 27 extends towards the position close to the charging port housing 3.

[0019] It should be noted that there can be multiple secondary flanges 23 and connecting bends 26, which can be determined according to the shape of the corresponding position of the charging port housing 3.

[0020] In a further embodiment of this example, the soft adhesive includes a first sealing edge 41, a connecting portion 42, and a second sealing edge 43. The first sealing edge 41 is interference-connected with a flange 22, and the second sealing edge 43 is interference-connected with a tail flange 24. The connecting portion 42 is disposed between the charging port side panel and the charging port housing 3.

[0021] In a further embodiment of this example, the first sealing edge 41 interferes with and extends through a flange 22 in a direction away from the charging port housing 3, and the second sealing edge 43 interferes with and extends through the tail flange 24 in a direction away from the charging port housing 3.

[0022] In a further embodiment of this example, the side panel 21, the first flange 22, the second flange 23, the last flange 24, the first bend 25, the connecting bend 26, and the last bend 27 are integrally formed.

[0023] The charging port side panel is designed with an outer side panel 21, a first flange 22, a second flange 23 and a rear flange 4 at the opening. The rear flange 24 of the outer side panel is a short side that is flipped outward again based on the conventional design of the second flange 23 of the outer side panel.

[0024] The charging port box consists of two parts: the charging port shell 3 and the soft rubber. The soft rubber is mainly used for sealing. There is a ring of injection-molded soft rubber around the outer perimeter of the charging port shell 3. In addition to the conventional design of the outermost first sealing edge 41, the soft rubber also has a second sealing edge 43 on the inner side.

[0025] After the charging port cover is installed, in addition to the conventional design, the first sealing edge 41 and the flange 22 of the outer side panel form a seal, and the second sealing edge 43 and the tail flange 24 of the outer side panel form a second seal.

[0026] With the above-described structural design, when encountering heavy rain or high-pressure water jets during car washes, the first seal can block most of the water from entering the vehicle. After some water penetrates through the first seal, the second seal is formed by the rear flange 24 of the side panel extending laterally above the secondary flange 23 of the side panel and forming a second seal with the second sealing edge 43. This makes it extremely difficult for water to pass through the second seal, further reducing the risk of leakage.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
