Description
Technical Field
[0001] The utility model belongs to the technical field of electric vehicle structure design, and particularly relates to an automobile charging port structure and an automobile. Background Art
[0002] An automobile charging port assembly generally includes a charging port seat and a charging port cover. The charging port is arranged on the charging port seat, and the charging port seat is installed in an installation hole on an outer side panel. For the needs of styling and other aspects, some vehicle models are designed with relatively obvious ridge line features on the outer side panel. However, for the charging port structure straddling both sides of the ridge line, it greatly increases the manufacturing cost of the outer side panel and also increases the difficulty of controlling the matching gap and surface difference between the charging port assembly and the outer side panel, which is likely to affect the overall vehicle appearance evaluation. This is because in the conventional charging port structure, the installation of the charging port seat is usually completed by stamping an isodepth stepped hole on the outer side panel that is consistent with the bending degree of the outer surface of the outer side panel. The upper stepped surface and the lower stepped surface of the isodepth stepped hole are embodied as an intersecting surface structure at a certain angle. Limited by the spatial layout of the mold, usually only the side trimming process can be used to trim the upper stepped surface to ensure the accuracy during trimming. Especially when the ridge line feature is obvious (with a large bending degree), the side trimming tool of the upper stepped surface will interfere with the positive trimming tool of the lower stepped surface, and the trimming process cannot be completed under the same set of molds, which is not conducive to accuracy control. As a result, it is difficult to control the matching gap and surface difference between the charging port seat and the outer side panel, and it also increases the manufacturing cost of the outer side panel.
[0003] Therefore, it is necessary to provide a new automobile charging port structure and an automobile, which are expected to help reduce the manufacturing cost of the charging port structure crossing the ridge line, help control the matching gap and surface difference between the charging port assembly and the outer side panel, and reduce the impact on the overall vehicle appearance evaluation. Summary of the Utility Model
[0004] In view of this, the purpose of the utility model is to provide an automobile charging port structure and an automobile, which can help reduce the manufacturing cost of the charging port structure crossing the ridge line, can help control the matching gap and surface difference between the charging port assembly and the outer side panel, and reduce the impact on the overall vehicle appearance evaluation.
[0005] To achieve the above object, the present utility model provides the following technical solutions: An automobile charging port structure, including an outer side panel and a charging port assembly disposed on the outer side panel. The outer side panel has a ridge line feature formed by bending the outer side panel. The outer side panel is provided with a charging port mounting hole that straddles the upper and lower sides of the ridge line feature. The charging port mounting hole extends toward the inner side of the vehicle body along its circumferential direction to form a hole wall. The hole wall is provided with an annular flanging extending toward the center line of the charging port mounting hole. The annular flanging has an upper flanging and a lower flanging, and the upper flanging and the lower flanging are coplanar or approximately coplanar; the charging port assembly includes a charging port seat fixedly installed on the annular flanging.
[0006] Further, the upper flanging or the lower flanging is set at the same depth as the corresponding outer surface of the outer side panel.
[0007] Further, the lower flanging is set at the same depth as the corresponding outer surface of the outer side panel.
[0008] Further, the depths of the left and right sides of the annular flanging relative to the outer surface of the outer side panel generally present a structure that is shallower at the top and deeper at the bottom.
[0009] Further, the charging port seat includes a seat body skeleton. The seat body skeleton is fixed in the space formed by the annular flanging through a clamping structure, and a plurality of limiting buckles that tightly abut against the annular flanging are arranged in the circumferential direction of the seat body skeleton.
[0010] Further, the plurality of limiting buckles include at least two first limiting buckles that tightly abut against the annular flanging in the front-rear direction of the vehicle body, and at least two second limiting buckles that tightly abut against the annular flanging in the up-down direction of the vehicle body.
[0011] Further, the clamping structure includes a flange plate provided at the end of the seat body skeleton and tightly pressed against the annular flanging in the lateral direction of the vehicle body, and a plurality of locking buckles provided on the outer peripheral surface of the seat body skeleton and used to cooperate with the flange plate to complete the locking of the annular flanging.
[0012] Further, there are four locking buckles, and two of them are in a group to respectively cooperate with the flange plate to complete the locking of the upper flanging and the lower flanging.
[0013] Further, at least two supporting protrusion parts that abut against the annular flanging are respectively provided at the positions of the flange plate corresponding to each locking buckle.
[0014] An automobile is equipped with the above-mentioned automobile charging port structure.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] In the structure of the vehicle charging port provided by the present utility model, it is beneficial to reduce the manufacturing cost of the charging port structure with a rib line, and it is beneficial to control the matching gap and surface difference between the charging port assembly and the outer panel of the side wall, reducing the impact on the overall vehicle appearance evaluation; specifically, by setting an annular flanging and fixedly installing the charging port seat on the annular flanging, the annular flanging can facilitate the positioning and installation of the charging port seat, thereby ensuring the assembly accuracy of the charging port assembly; since the upper flanging and the lower flanging are coplanar or approximately coplanar, when trimming the upper and lower flanging, the trimming tool can enter from one angle (i.e., not affected by the bending degree at the rib line feature), and positive trimming can be used to complete the accuracy control of the flanging edge. Only one set of positive trimming dies is required to complete the trimming process, which can effectively save the development of side trimming dies, reduce the manufacturing stations for manufacturing the outer panel of the side wall, and reduce the manufacturing cost; at the same time, it is more conducive to stamping processing, and the edges of the upper and lower flanging can be effectively guaranteed, so that the matching gap and surface difference accuracy between the charging port assembly and the outer panel of the side wall can be effectively controlled;
[0017] The vehicle provided by the present utility model is beneficial to have a relatively low manufacturing cost while having a good appearance evaluation.

Detailed implementation manners
[0027] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the diagrams provided in the following embodiments are only used to illustrate the basic concept of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0028] Please refer to Figures 1-7, in this embodiment, an automobile charging port structure is disclosed, which includes an outer side panel 1 and a charging port assembly disposed on the outer side panel 1. The outer side panel 1 has a ridge line feature formed by bending the outer side panel 1. The outer side panel 1 is provided with a charging port mounting hole 11 that straddles the upper and lower sides of the ridge line feature. The charging port mounting hole 11 extends inward along its circumferential direction towards the vehicle body to form a hole wall. The hole wall is provided with an annular flanging 12 extending towards the center line of the charging port mounting hole 11. The annular flanging 12 has an upper flanging 12a and a lower flanging 12b, and the upper flanging 12a and the lower flanging 12b are coplanar or approximately coplanar; the charging port assembly includes a charging port seat 2 fixedly installed on the annular flanging 12; of course, the charging port assembly also includes structures such as a charging port cover. The charging port cover is generally rotatably arranged on the charging port seat 2 through a hinge. The charging port is provided on the charging port seat 2. When not in use, the charging port cover is closed to shield the charging port. This part has the same structure as the traditional charging port assembly and will not be elaborated here; it can be understood that the ridge line features on the outer side panel 1 are basically arranged along the front and rear directions of the vehicle body. The surface of the outer side panel 1 has a relatively obvious bending change at the ridge line feature. The charging port mounting hole 11 straddles the ridge line feature in the up and down direction; here, among the upper flanging 12a and the lower flanging 12b, the side closer to the upper part of the vehicle body is the upper side, and the side closer to the lower part of the vehicle body is the lower side; of course, the annular flanging 12 also has flanging parts on both sides in the front and rear directions of the vehicle body, which together with the upper flanging 12a and the lower flanging 12b form a complete annular flanging 12; it can be understood that for a charging port with a rectangular or approximately rectangular structure, the four corners of the annular flanging 12 usually adopt a rounded corner transition structure; for a charging port with a circular structure, the same principle applies, and only its special rectangular hole needs to be understood;
[0029] In the above-provided structure of the vehicle charging port, it is beneficial to reduce the manufacturing cost of the charging port structure with an over-edge line. It is beneficial to control the matching clearance and surface difference between the charging port assembly and the outer panel 1 of the side wall, reducing the impact on the overall vehicle appearance evaluation. Specifically, by setting the annular flanging 12 and fixedly installing the charging port seat 2 on the annular flanging 12, the annular flanging 12 can facilitate the positioning and installation of the charging port seat 2, thereby ensuring the assembly accuracy of the charging port assembly. More specifically, the annular flanging 12 can provide lateral body limit for the charging port seat 2 and also facilitate providing circumferential limit for the charging port seat 2, thus facilitating the control of the matching clearance and surface difference between the charging port assembly and the outer panel 1 of the side wall. Since the upper flanging 12a and the lower flanging 12b are set to be parallel or approximately parallel, when trimming the upper and lower flangings, the trimming tool can enter at one angle, that is, it is not affected by the bending degree at the edge line feature (in the traditional structure, the charging port mounting holes 11 are basically of equal depth, that is, the upper and lower flangings will follow the bending at the edge line and be arranged at a certain angle). Positive trimming can be used to complete the accuracy control of the flanging edge. Only one set of positive trimming dies is required to complete the trimming process, which can effectively save the development of side trimming dies, reduce the manufacturing stations for manufacturing the outer panel of the side wall, and reduce the manufacturing cost. At the same time, it is more conducive to stamping processing, and the edges of the upper and lower flangings can be effectively guaranteed, so that the matching clearance and surface difference accuracy between the charging port assembly and the outer panel 1 of the side wall can be effectively controlled.
[0030] In this embodiment, the upper flanging 12a or the lower flanging 12b is set to be of equal depth relative to the corresponding outer surface of the outer panel 1 of the side wall. It can be understood that the equal-depth setting here means that the distance between the upper flanging 12a or the lower flanging 12b and the corresponding outer surface of the outer panel 1 of the side wall is the same, that is, the plane where the upper flanging 12a or the lower flanging 12b is located is parallel to the tangent plane of the corresponding outer surface of the outer panel 1 of the side wall at the edge of the charging port mounting hole 1. Here, it is preferably to set the lower flanging 12b to be of equal depth relative to the corresponding outer surface of the outer panel 1 of the side wall. It can be understood that in order to ensure that the upper flanging 12a or the lower flanging 12b is coplanar or approximately coplanar, since the charging port straddles the edge line feature, the other flanging will inevitably show unequal depth with the corresponding outer surface of the outer panel 1 of the side wall. In this structural design, by retaining one of the upper and lower flangings as an equal-depth structure, it is beneficial to the stamping of the equal-depth side. Only the angle of the other flanging needs to be adjusted based on this side, which is beneficial to further simplifying the design of the stamping die and further reducing the manufacturing cost.
[0031] In this embodiment, the lower flanging 12b is set to be of equal depth relative to the corresponding outer surface of the outer panel 1 of the side wall. This structure is simple. Only the angle of the upper flanging 12a needs to be adjusted to be coplanar or approximately coplanar with the lower flanging 12b, which can better adapt to the change of the edge line feature, make the whole easier to process, reduce the adjustment of the die, and further reduce the manufacturing cost.
[0032] In this embodiment, the depths of the left and right sides of the annular flange 12 relative to the outer surface of the outer side panel 1 generally present a structure that is shallower at the top and deeper at the bottom; that is, the depth of the upper part of the flange on the left and right sides corresponding to the outer surface of the outer side panel 1 is less than the depth of the lower part corresponding to the outer surface of the outer side panel 1. This structural design is conducive to adapting to the changes in the ridge line characteristics, ensuring that the depth of the lower flange 12b does not need to be designed too deep, which is conducive to ensuring the stamping processing quality and improving the aesthetics at the same time.
[0033] In this embodiment, the charging port seat 2 includes a seat body skeleton 21. The seat body skeleton 21 is fixed in the space formed by the annular flange 12 through a clamping structure 22, and a plurality of limiting buckles 23 that are tightly abutted against the annular flange 12 are arranged circumferentially on the seat body skeleton 21. Generally, the seat body skeleton 21 is injection-molded, and a charging port can be arranged inside it. Referring to the design of the existing charging port seat body skeleton, it will not be elaborated here. In this structural design, by using a plurality of limiting buckles 23 to abut tightly against the annular flange 12, the circumferential positioning of the charging port seat 2 can be completed. Since the limiting buckles 23 are used for abutting, compared with large-area fitting and positioning, it is easier to ensure the assembly accuracy, further improving the clearance matching accuracy between the charging port assembly and the outer side panel 1 and ensuring the appearance aesthetics. The assembly is completed by using the clamping structure 22, which is convenient for assembly, conducive to further reducing the manufacturing cost, and can also help to ensure the assembly accuracy in the lateral (width direction) of the vehicle body.
[0034] In this embodiment, the plurality of limiting buckles 23 include at least two first limiting buckles 23a that are tightly abutted against the annular flange 12 in the front-rear direction of the vehicle body, and at least two second limiting buckles 23b that are tightly abutted against the annular flange 12 in the up-down direction of the vehicle body. Specifically, there are two first limiting buckles 23a, which are symmetrically arranged in the middle of both sides of the seat body skeleton 21 in the front-rear direction of the vehicle body. Here, there are four second limiting buckles 23b, and the four second limiting buckles 23b are correspondingly distributed at the four corners of the annular flange 12. A limiting portion for the second limiting buckles 23b to abut and be limited is arranged at the rounded corner part of the annular flange 12. Through the first limiting buckles 23a and the second limiting buckles 23b, the positioning accuracy of the charging port seat 2 and the annular flange 12 can be effectively ensured, and at the same time, the probability of quality risks such as abnormal noises occurring in the charging port seat 2 during vehicle driving can be effectively reduced, ensuring the driving experience of the passengers and drivers. At the same time, the layout is reasonable and the limiting effect is good. Especially for the charging port installation holes with unequal depths, a reasonable limiting structure is required to ensure the installability.
[0035] In this embodiment, the clamping structure 22 includes a flange plate 22a provided at the end of the seat body skeleton 21 and pressed against the annular flange 12 in the vehicle body transverse direction, and a plurality of locking buckles 22b provided on the outer peripheral surface of the seat body skeleton 21 and used to cooperate with the flange plate 22a to complete the locking of the annular flange 12. Here, the flange plate 22a and the seat body skeleton 21 are usually integrally injection-molded; the clamping structure 22 has a simple structure, high installation convenience and reliability, which is beneficial to further reduce the risk of abnormal noise in the charging port.
[0036] In this embodiment, there are four locking buckles 22b, and they are divided into two groups in pairs to respectively cooperate with the flange plate 22a to complete the locking of the upper flange 12a and the lower flange 12b; it has a simple structure, reasonable layout and good locking effect.
[0037] In this embodiment, at least two supporting protrusion parts 22c that abut against the annular flange 12 are respectively provided at the position of the flange plate 22a corresponding to each locking buckle 22b; specifically, there are two supporting protrusion parts 22c here, and the supporting protrusion parts 22c and the flange plate 22a are an integral structure. The two supporting protrusion parts 22c are distributed on both sides of the locking buckle 22b at the corresponding position. It can be understood that there are a total of eight supporting protrusion parts 22c corresponding to the four locking buckles 22b; at the same time, adding the supporting protrusion parts 22c is beneficial to enhancing the structural strength of the clamping part, and at the same time ensuring that it can be closely attached to the annular flange 12, which is beneficial to reducing the assembly error, further ensuring the surface difference control accuracy, and improving the aesthetics of the whole vehicle.
[0038] In this embodiment, an automobile is also disclosed, which has the structure of the automobile charging port as described above; this automobile is beneficial to having a relatively low manufacturing cost while having a good appearance evaluation.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
