Description

Technical Field

[0001] The present invention relates to a jacking cover whose mask is used for a jacking flange for jacking an electric vehicle. Background Art

[0002] In the case of an electric vehicle, the importance of the underbody cover in ensuring fuel efficiency is emerging, and its application is expanding. The aerodynamic contribution of the underbody cover can be improved together with the improvement of the upper body, and the aerodynamic improvement effect of the shape of the underbody cover is known. There is a trend to increase the mask area to improve aerodynamics and to improve the underbody cover into a structure for ensuring a sense of wholeness.

[0003] As Figure 1 shown, the underbody cover 20 masks the vehicle body 11 by connecting the battery part 13 to the side sill forming member 12 below the vehicle body 11.

[0004] However, since the side sill under cover, which has a significant influence on the aerodynamic effect, is joined in a structure that masks the jacking flange 21 (for example, jacking the vehicle at four positions) formed below the vehicle body 11, there is a problem that it is difficult to use the previously used jacking points.

[0005] To solve this problem, there are cases where the forming member is separated to apply a separate pad or the jacking flange is used, but in this case, there is a limitation in the reduction of aerodynamic performance. Summary of the Invention

[0006] The present invention is dedicated to solving the above problems and aims to provide a jacking cover and a jacking cover device for an electric vehicle that can ensure aerodynamic performance regardless of the jacking method (such as a jacking flange or a separate jacking pad) and can be applied to various layouts (such as the shape and position of the battery).

[0007] The jacking cover for an electric vehicle according to one aspect of the present invention is connected to the underbody cover to mask the lower part of the jacking flange, wherein one end of the jacking cover is connected to the end of the underbody cover on the battery part side, and the other end of the jacking cover is connected to the end of the underbody cover on the side sill forming member side or the side sill forming member.

[0008] In addition, the jacking cover may include: a lower cover part, a side cover part, and an upper cover part. The lower cover part corresponds to the lower part of the jacking cover. One end of the side cover part is formed to extend upward from one end of the lower cover part, and one end of the upper cover part is formed to extend laterally from the other end of the side cover part. Wherein, the lower cover part may be connected to the end of the underbody cover on the battery part side, and the upper cover part may be connected to the end of the underbody cover on the side sill forming member side.

[0014] In addition, a plurality of first latching portions can be formed.

[0015] In addition, the first latching portion can be formed to extend downward from the underbody cover and can have a lower end portion that is connected to a first latching engagement flange formed with a bent hook-like portion.

[0016] In addition, the first latching portion can be formed to project laterally after extending upward from the upper cover, and the projecting portion formed to project laterally can be connected to the hook-like portion of the first latching engagement flange.

[0017] In addition, the first latching portion can be formed to extend downward from the projecting portion, and a latching extension portion that can be elastically deformed by an external force can be formed.

[0018] In addition, the jacking cover can further include a second latching portion that extends to project from both side end portions of the jacking cover and is connected to the underbody cover.

[0019] In addition, the upper end portion of the second latching portion can be formed to project laterally, and the projecting portion of the second latching portion can be connected to a second latching engagement flange formed to extend upward from the underbody cover.

[0020] In particular, the thickness of the lower end portion of the second latching portion can be formed to be smaller than the thickness of its middle portion.

[0021] In some examples, a drain hole can be formed in the lower cover portion, and a display portion that is visually distinguishable from other portions of the side cover portion can be formed on the side cover portion.

[0022] In addition, the jacking flange can be formed on the underbody cover that shields the vehicle body under the vehicle body by connecting the battery portion and the side sill molding.

[0023] In addition, the jacking cover can be detachable from the underbody cover.

[0024] In addition, the lower end line of the jacking cover can have a structure that extends collinearly with the lower end line of the battery section.

[0025] According to the jacking cover device of the present invention, regardless of the jacking method (e.g., jacking flange or separate jacking pad), the aerodynamic performance can be ensured by the detachable jacking cover.

[0026] In addition, the jacking cover can be applied to various layouts, such as the shape and position of the battery.

[0027] Therefore, the stability of the battery can be ensured by protecting the battery from foreign objects. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] To fully understand the present invention, the operational advantages of the present invention, and the objectives to be achieved by practicing the present invention, reference should be made to the accompanying drawings, which illustrate embodiments of the present invention and the content described in the drawings.

[0039] In the present invention, descriptions or repeated descriptions of known technologies that may unnecessarily obscure the key points of the present invention may be reduced or omitted.

[0040] Figure 2 For showing a schematic diagram of the jacking cover Figure 3 For showing Figure 2 a schematic diagram of the side shape of the jacking cover of Figure 4 a schematic diagram of the cross-sectional shape in the state where the jacking cover is installed. In addition,

[0041] Hereinafter, reference will be made to Figures 2 to 4 describe a jacking cover and a jacking cover device for an electric vehicle according to one or more embodiments of the present invention.

[0042] In some embodiments, the jacking cover device includes a underbody cover 20 for covering the underbody of the vehicle body 11 by connecting the battery part 13 and the side beam forming member 12 below the vehicle body 11, and a jacking cover 100 detachably mounted on the underbody cover 20 to cover the lower part of the jacking flange 21 formed on the underbody cover 20.

[0043] The jacking cover 100 may include a lower cover part 120 and a side cover part 130, and further include an upper cover part 150.

[0044] The lower cover part 120 may correspond to the lower part of the jacking cover 100. One end of the side cover part 130 may be formed to extend upward from one end of the lower cover part 120 to cover the side part of the vehicle body 11, and the side cover part 130 may be formed to slope upward. Alternatively, the side cover part 130 may be formed to be curved and slope upward.

[0045] In addition, the upper cover part 150 may be formed to extend laterally from the other end of the side cover part 130, and the upper cover part 150 may be omitted when the side cover part 130 serves as the upper cover part 150.

[0046] Drainage holes 121 may be formed in the lower cover part 120, and water may be discharged through the drainage holes 121 in the driving state or the stopped state.

[0047] In addition, a display part 131 may be formed on the side cover part 130 to provide visibility so that the user can check whether the jacking cover 100 is installed from the side. The display part 131 may be formed to be different from other parts of the side cover part 130 by embossing, engraving, coloring, etc.

[0048] Next, in order to install one side of the lifting cover 100 on the vehicle bottom cover 20, a first connecting portion 110 may be formed on the lower cover portion 120. The first connecting portion 110 extends to laterally protrude from the other end corresponding to this side of the battery portion 13 and is connected to the vehicle bottom cover 20, and a plurality of first connecting portions 110 may be formed.

[0049] In some embodiments, the first connecting portion 110 is bent in a stepped manner, higher than the lower cover portion 120, and then extends to protrude laterally.

[0050] In addition, as shown in the figure, the first connecting portion 110 is connected by being inserted into a connecting hole formed in the end of the vehicle bottom cover 20 on this side of the battery portion 13.

[0051] In addition, in order to install the other side of the lifting cover 100 on the vehicle bottom cover 20, a first clamping portion 160 may be formed on the upper cover portion 150. The first clamping portion 160 extends to protrude from the other end corresponding to this side of the side beam forming member 12 and is connected to the vehicle bottom cover 20, and a plurality of first clamping portions 160 may be formed. The end of the other side of the lifting cover 100 may be directly connected to the end of the vehicle bottom cover 20 on this side of the side beam forming member or the side beam forming member.

[0052] As Figure 4 and Figure 5 shown, the first clamping portion 160 is formed to extend downward from the vehicle bottom cover 20, and the lower end portion is connected to the first clamping engagement flange 22 having a bent shape.

[0053] Since the first clamping portion 160 extends upward from the upper cover portion 150 and then is formed to protrude laterally, when connected, the protruding portion crosses the hook portion of the first clamping engagement flange 22. Therefore, the protruding portion and the hook portion are connected, so that the first clamping portion 160 is connected without moving backward.

[0054] In addition, a clamping extension portion 161 is formed to extend downward from the protruding portion. Therefore, the clamping extension portion 161 is exposed downward from the first clamping engagement flange 22, so that the user can sense the clamping extension portion 161 from the side. As shown in the figure, the clamping extension portion 161 is formed to have an elastic bending structure together with the shape of the first clamping portion 160.

[0055] Therefore, when the user pushes the clamping extension portion 161 upward against the upper cover portion 150 by applying force, the first clamping portion 160 can be bent so that the protruding portion comes out of the first clamping engagement flange 22 to allow the lifting cover 100 to be separated from the vehicle bottom cover 20.

[0056] In some examples, for a more stable connection, second engaging portions 140 extending to protrude from both side ends of the lifting cover 100 may be formed on both side ends of the lifting cover 100, which will be described below.

[0057] Figure 6 FIG. is a schematic diagram showing the process of installing the lifting cover. Figure 7 FIG. is a schematic diagram showing the installation state.

[0058] As Figure 6 shown, the lifting cover 100 is temporarily connected by inserting the first connecting portion 110 into a connecting hole formed in the end portion on the side of the battery portion of the underbody cover 20.

[0059] As shown in the figure, since the first connecting portion 110 is formed in a stepped manner and is higher than the lower cover portion 120, the stepped hooking structure facilitates the temporary connection to the connecting hole.

[0060] As described above, after temporarily connecting the first connecting portion 110, the lifting cover 100 is rotated counterclockwise in the figure, and the first engaging portion 160 and the second engaging portion 140 are respectively connected to the first engaging flange 22 and the second engaging flange 23 to be completely connected, as Figure 7 shown. Due to the hooking structure, by applying a force to the rear surfaces of the first engaging portion 160 and the second engaging portion 140 and pressing them, the first engaging portion 160 and the second engaging portion 140 are completely connected.

[0061] Referring to Figure 8 and Figure 9 , Figure 8 is a cross-section along line X-X in Figure 7 , Figure 9 is Figure 8 an enlarged schematic view of part B in

[0062] In addition, since the corresponding second engaging flange 23 is formed to extend upward from the underbody cover 20 by a predetermined length, the protruding portion of the upper end of the second engaging portion 140 is connected by crossing the end of the second engaging flange 23.

[0063] In addition, the second engaging portion 140 is formed such that the thickness of the lower end portion is smaller than that of the middle portion. Therefore, when the upper cover portion 150 or the side cover portion 130 moves downward after releasing the connection of the first engaging portion 160, Figure 9 the second engaging portion 140 shown in the figure elastically deforms counterclockwise in the figure due to the smaller thickness of its lower end portion, so that the connection with the second engaging flange 23 can be released.

[0064] According to the present invention, after separating the jacking cover by the above method, the vehicle can be jacked up by arranging a jacking mechanism as shown in the example of Figure 10 under the underbody cover.

[0065] In addition, as shown in Figure 11 , the lower cover portion 120 of the jacking cover 100 joined to the underbody cover 20 may have a structure extending collinearly with the lower end line of the battery portion 13, so as to allow the jacking cover 100 to protect the battery from foreign objects as a safety component.

[0066] The jacking cover is formed collinearly with the battery portion provided under the vehicle floor and is connected to the side sill molding 12 to protect the vehicle body from foreign objects and form a more complete design.

[0067] Although the present invention has been described above with reference to the exemplary drawings, the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the present invention. Therefore, examples of such modifications or changes should be included in the claims of the present invention, and the scope of the present invention should be interpreted based on the appended claims.
