Description

Technical Field

[0001] This application relates to the technical field of vehicle charging ports, and particularly to a charging port box structure, a charging port box assembly, and a vehicle. Background Art

[0002] The charging port box generally consists of a port box, a hinge box, and a port cover. The shape of the hinge box is mostly designed as a curved structure to facilitate the core-pulling demolding of the hinge box. This demolding method has great limitations on the shape of the hinge box, resulting in a relatively fixed external design of the hinge box and unable to meet the diversified design requirements of the external shape of the hinge box. In addition, this demolding method is not convenient for demolding, resulting in a low processing efficiency of the charging port box. Utility Model Content

[0003] This application provides a charging port box structure, a charging port box assembly, and a vehicle to solve the problem that the external design of the hinge box of the charging port box in the known technology is fixed due to the core-pulling demolding method.

[0004] In a first aspect, this application provides a charging port box structure, including a first box body, a second box body, and a rotating cover; the first box body is configured to accommodate a charging connector structure; the second box body is connected to one side of the first box body, an installation cavity is provided inside the second box body, and a demolding port is provided on one side of the second box body, and the demolding port communicates with the installation cavity; the rotating cover is integrally formed on one side of the second box body, and the rotating cover is configured to be rotatable relative to the second box body for opening or closing the demolding port.

[0005] In a possible implementation manner, the rotating cover includes:

[0006] A thinning part, one end of which is integrally formed on one side of the second box body, and the thinning part is configured to be elastically deformable;

[0007] A cover part, integrally formed at the other end of the thinning part away from the second box body, and the cover part is used to close the demolding port.

[0008] In a possible implementation manner, the charging port box structure further includes a connection assembly. When the rotating cover closes the demolding port, the rotating cover is relatively fixed to the second box body through the connection assembly.

[0009] In a possible implementation manner, the connection assembly includes:

[0010] A first clamping part, provided on the rotating cover;

[0011] A second clamping part, provided on the second box body;

[0012] Wherein, the first clamping part is used to be clamped with the second clamping part.

[0013] In a possible implementation manner, a clamping groove is provided on the first clamping portion, and the clamping groove is used to accommodate the second clamping portion;

[0014] Wherein, the second clamping portion is located on the rotation path of the first clamping portion, and the first clamping portion can rotate to cross over the second clamping portion so that the second clamping portion is clamped in the clamping groove.

[0015] In a possible implementation manner, the surface of the second clamping portion on the side away from the second box body is set as a guiding surface. Along the first rotation direction, the guiding surface extends obliquely from its end close to the rotating cover towards the side away from the second box body to the end of the guiding surface away from the rotating cover. The first rotation direction is set as the direction in which the rotating cover rotates towards the side of the second box body;

[0016] Wherein, the guiding surface is used to abut against the first clamping portion to guide the first clamping portion to rotate to cross over the second clamping portion.

[0017] In a possible implementation manner, along the first rotation direction, the end face of the second clamping portion at the end away from the rotating cover is set as a limiting surface. The first rotation direction is set as the direction in which the rotating cover rotates towards the side of the second box body;

[0018] Wherein, when the second clamping portion is clamped in the clamping groove, the limiting surface abuts against the first clamping portion to limit the first clamping portion from rotating in the second rotation direction, and the second rotation direction is opposite to the first rotation direction.

[0019] In a possible implementation manner, a receiving cavity is formed on one side of the first box body. The receiving cavity communicates with the installation cavity, and the receiving cavity is used to accommodate the charging connector structure.

[0020] In a second aspect, the present application further provides a charging port box assembly, including a charging port cover and the above-mentioned charging port box structure. The charging port cover is movably connected to the charging port box structure and is used to open or close the receiving cavity of the charging port box structure.

[0022] The charging port box structure of the present application has a demolding port opened on the second box body, and a rotating cover integrally formed with the second box body is provided on the second box body. The rotating cover can rotate relative to the second box body to open or close the demolding port. When the second box body is injection-molded, the rotating cover can be opened to expose the installation cavity of the second box body, so that the second box body with the rotating cover in the open state can be injection-molded by the way of upper and lower mold clamping, avoiding the limitation of the external shape structure of the second box body by using the core-pulling demolding method, thus making the external shape design of the second box body more diverse. Moreover, the demolding method of the present application is easier to demold, which can improve the processing efficiency of the charging port box structure. In addition, the rotating cover and the second box body are connected by an integral molding method, and the rotating cover can be directly processed on the second box body, reducing the assembly process between the rotating cover and the second box body, and further improving the production efficiency of the charging port box structure.

Further, unless clearly defined herein, terms such as those defined in a general dictionary should be construed to have a meaning consistent with their meaning in the relevant art and the content of this application and will not be construed in an idealized or overly formal sense.

[0072] The following will refer to the drawings for a further detailed description of the specific embodiments of the present application.

[0073] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a vehicle 300, including a vehicle body 1 and a charging port box assembly 200, and the charging port box assembly 200 is connected to the vehicle body 1. The position of the charging port box assembly 200 relative to the vehicle body 1 is not specifically limited in the present application. The charging port box assembly 200 can be located on either side of the vehicle body 1 in the length direction or on either side of the vehicle body 1 in the width direction.

[0074] The vehicle 300 further includes a battery module 2 and a charging connector structure 3. The battery module 2 is installed on the vehicle body 1, and the charging connector structure 3 is installed in the charging port box assembly 200 to protect the charging connector structure 3 through the charging port box assembly 200. The charging connector structure 3 is electrically connected to the battery module 2, and the charging connector structure 3 can also be externally connected to a charging pile 4. The charging pile 4 charges the battery module 2 through the charging connector structure 3 to achieve charging of the vehicle 300.

[0075] As Figure 2 and Figure 3 shown, and referring to Figure 1 , an embodiment of the present application further provides a charging port box assembly 200, including a charging port cover 10 and a charging port box structure 100.

[0076] The charging port box structure 100 is provided with a receiving cavity 21, and the charging connector structure 3 is installed in the receiving cavity 21. The charging port cover 10 is movably connected to the charging port box structure 100 and is used to open or close the receiving cavity 21 of the charging port box structure 100, so that when charging is required, the charging port cover 10 can be moved to open the receiving cavity 21, and thus the plug of the charging pile 4 can be inserted into the charging connector structure 3 in the receiving cavity 21. In addition, after charging is completed, the charging port cover 10 can be moved again to reset it and close the receiving cavity 21, thereby preventing the charging connector structure 3 from being exposed and easily damaged.

[0077] As Figures 4 to 6 shown, and referring to Figure 1 , an embodiment of the present application further provides a charging port box structure 100, including a first box body 20, a second box body 30 and a rotating cover 40.

[0078] The first box body 20 is configured to accommodate the charging connector structure 3, and the second box body 30 is connected to one side of the first box body 20. An installation cavity 31 is provided inside the second box body 30, and a demolding port 32 is provided on one side of the second box body 30. The demolding port 32 communicates with the installation cavity 31. The rotating cover 40 is integrally formed on one side of the second box body 30, and the rotating cover 40 is configured to be rotatable relative to the second box body 30 and is used to open or close the demolding port 32.

[0079] Thus, for the charging port box structure 100 of the present application, by opening a demolding port 32 on the second box body 30 and providing a rotating cover 40 integrally formed with the second box body 30, the rotating cover 40 can rotate relative to the second box body 30 to open or close the demolding port 32. When the second box body 30 is injection-molded, the rotating cover 40 can be opened to expose the installation cavity 31 of the second box body 30, so that the second box body 30 with the rotating cover 40 in the open state can be injection-molded by the way of upper and lower mold clamping, avoiding the core-pulling demolding method of the second box body 30 from restricting the external shape structure of the second box body 30, thus making the external shape design of the second box body 30 more diverse. Moreover, the demolding method of the present application is easier to demold, which can improve the processing efficiency of the charging port box structure 100. In addition, the rotating cover 40 and the second box body 30 are connected in an integrally formed manner, and the rotating cover 40 can be directly processed on the second box body 30, reducing the assembly process between the rotating cover 40 and the second box body 30, and further improving the production efficiency of the charging port box structure 100.

[0080] For the convenience of subsequent reading, the present application introduces the first direction Y, the second direction X, and the third direction Z to describe the embodiments of the present application. The first direction Y, the second direction X, and the third direction Z can be three non-parallel straight-line directions in space; further, the first direction Y, the second direction X, and the third direction Z can be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction Y is taken as the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction X is taken as the X-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Z is taken as the Z-axis direction of the coordinate axis of the three-dimensional coordinate system as an example for description.

[0081] Please combine with Figures 4 to 6 again, and refer to Figure 1 In an embodiment, the first box body 20 is generally a square structure. Along the first direction Y, an accommodation cavity 21 is opened on the end face of one end of the first box body 20. The accommodation cavity 21 extends along the first direction Y towards the end face of the other end of the first box body 20 and the accommodation cavity 21 does not penetrate the first box body 20.

[0082] It can be understood that the first box body 20 can also be a cylindrical structure or other shaped structures. In the present application, the specific shape of the first box body 20 is not limited in the present application.

[0083] Along the first direction Y, a wiring port 22 is opened on the end face of the other end of the first box body 20. The wiring port 22 communicates with the accommodation cavity 21, and the wiring port 22 can allow the connecting wire between the battery module 2 and the charging connector structure 3 to pass through.

[0084] In this embodiment, along the second direction X, the second box body 30 is integrally formed on one side of the first box body 20. Along the second direction X, a through hole 23 is formed in the inner wall of the accommodating cavity 21 near the second box body 30, and the through hole 23 communicates with the accommodating cavity 21 and the installation cavity 31.

[0085] The charging port cover 10 includes a cover portion 11 and a rotating portion 12. The cover portion 11 is generally a flat plate-like structure and is used to close the opening of the accommodating cavity 21. The rotating portion 12 is generally a curved structure and is approximately in a "gooseneck" structure, so as to facilitate the charging port cover 10 to rotate relative to the charging port box structure 100 in a limited space.

[0086] One end of the rotating portion 12 is integrally formed on the cover portion 11, and the other end of the rotating portion 12 passes through the through hole 23 and extends into the installation cavity 31. Moreover, the end of the rotating portion 12 extending into the installation cavity 31 is rotatably engaged with the second box body 30, so that the charging port cover 10 can rotate relative to the first box body 20 and the second box body 30. The cover portion 11 can be rotated to abut against the end face of the first box body 20 where the accommodating cavity 21 is formed, and the opening of the accommodating cavity 21 is closed by the cover portion 11. In this application, the structure for realizing the rotational cooperation between the rotating portion 12 and the second box body 30 is not specifically limited, and it can be a hinge structure or the like.

[0087] It should be noted that for the existing second box body 30 designed to adapt to the "gooseneck" structure of the rotating portion 12, the second box body 30 is also generally in a "gooseneck" structure. In addition, along the first direction Y, the end faces at both ends of the second box body 30 are both curved surfaces, and the two curved surfaces need to be concentric, so as to facilitate the second box body 30 to be smoothly core-pulled and demolded from the through hole 23 when processed by an injection molding process. Compared with this application, this demolding method is inconvenient for demolding and has a low production efficiency.

[0088] It can be understood that in other embodiments, the second box body 30 is detachably connected to the first box body 20, so as to replace different first box bodies 20 or second box bodies 30 according to actual design requirements. For example, the second box body 30 and the first box body 20 can be connected by fasteners such as bolts.

[0089] In addition, in other embodiments, the rotating portion 12 and the cover portion 11 can also be connected in a detachable manner, so as to replace the adapted rotating portion 12 or cover portion 11 according to different charging port box structures 100. For example, the rotating portion 12 and the cover portion 11 can be connected by a snap connection.

[0090] Please refer to Figures 5 to 7 In one embodiment, along the first direction Y, a demolding port 32 is formed on one side of the second box body 30, and the demolding port 32 and the wiring port 22 are located on the same side of the charging port box structure 100.

[0091] In particular, the diameter of the demolding opening 32 should be set large enough so that the demolding opening 32 can cover the end face of the second box body 30 where the demolding opening 32 is provided, to ensure that when the second box body 30 is processed by the upper and lower mold injection molding process, the part of the mold used to process the installation cavity 31 can smoothly leave the installation cavity 31 from the demolding opening 32.

[0092] In this embodiment, the rotating cover 40 includes a thinning portion 41 and a cover portion 42.

[0093] Along the second direction X, one end of the thinning portion 41 is integrally formed on the side of the second box body 30 away from the first box body 20. The cover portion 42 is integrally formed at the other end of the thinning portion 41 away from the second box body 30. The shape of the cover portion 42 is adapted to the demolding opening 32 to completely close the demolding opening 32 through the cover portion 42, so as to prevent the rotating portion 12 installed in the installation cavity 31 from being exposed outside the second box body 30.

[0094] In particular, the thinning portion 41 is configured to be elastically deformable. The thinning portion 41 is thinned relative to the cover portion 42 so that the thickness of the thinning portion 41 is less than the thickness of the cover portion 42, thereby reducing the strength and stiffness of the thinning portion 41, enabling the thinning portion 41 to be bent to adjust the position of the cover portion 42 relative to the second box body 30, and further realizing the rotation of the cover portion 42 relative to the second box body 30.

[0095] Please also combine Figures 5 to 7 , in an embodiment, the charging port box structure 100 further includes a connection assembly 50. When the rotating cover 40 closes the demolding opening 32, the rotating cover 40 is relatively fixed to the second box body 30 through the connection assembly 50 to prevent the rotating cover 40 from shifting and no longer closing the demolding opening 32.

[0096] Specifically, the connection assembly 50 includes a first clamping portion 51 and a second clamping portion 52. The first clamping portion 51 is provided on the rotating cover 40, and the second clamping portion 52 is provided on the second box body 30. Among them, the first clamping portion 51 is used to be clamped with the second clamping portion 52 to realize the clamping between the rotating cover 40 and the second box body 30 through the first clamping portion 51 and the second clamping portion 52.

[0097] It can be understood that in other embodiments, the rotating cover 40 and the second box body 30 can also be connected by means of plugging or bolt connection. In this application, the specific structure of the connection assembly 50 is not limited.

[0098] In this embodiment, the number of the second clamping portions 52 is set to four. Along the third direction Z, two second clamping portions 52 are respectively provided on the side walls of the opposite sides of the second box body 30. In addition, the two second clamping portions 52 located on the same side of the second box body 30 are spaced apart along the second direction X, and the two second clamping portions 52 located on the same side of the second box body 30 are respectively located at both ends of the side wall of the second box body 30 in the second direction X, so as to ensure that the rotating cover 40 and the second box body 30 can be tightly connected, and to prevent partial positions of the demolding opening 32 from not being completely closed. The positions of the two second clamping portions 52 on one side of the second box body 30 are correspondingly arranged with the positions of the two second clamping portions 52 on the other side of the second box body 30.

[0099] It can be understood that the positions of the two second clamping portions 52 on one side of the second box body 30 and the positions of the two second clamping portions 52 on the other side of the second box body 30 may not be correspondingly arranged. In addition, the number of the second clamping portions 52 may also be six, eight or other numbers, and the specific number of the second clamping portions 52 and the positional relationship with respect to the second box body 30 are not specifically limited in this application.

[0100] In this embodiment, the number of the first clamping portions 51 is the same as the number of the second clamping portions 52, and the positions of the first clamping portions 51 are adapted to the positions of the second clamping portions 52, so that when the rotating cover 40 closes the demolding opening 32, the first clamping portions 51 can be docked with the second clamping portions 52 and be engaged with each other.

[0101] Please also refer to Figures 5 to 7 , in an embodiment, the second box body 30 includes side plates 301 and a back plate 302. The number of the side plates 301 is two. Along the third direction Z, the two side plates 301 are spaced apart. The back plate 302 is substantially a curved plate, and the back plate 302 is connected between the two side plates 301, and an installation cavity 31 is formed by enclosing the two side plates 301 and the back plate 302. In addition, the back plate 302 and the two side plates 301 are integrally formed.

[0102] Specifically, one end of the back plate 302 extends substantially along the second direction X and is connected to the side wall of the first box body 20, and the other end of the back plate 302 extends substantially along the first direction Y. Along the first direction Y, both side plates 301 extend beyond the back plate 302, and the second clamping portions 52 are located in the regions where the side plates 301 extend beyond the back plate 302.

[0103] The charging port box structure 100 has a defined first rotation direction S1 and a second rotation direction S2, and the directions of the first rotation direction S1 and the second rotation direction S2 are opposite. Among them, the first rotation direction S1 is set as the direction in which the rotating cover 40 rotates toward the side of the second box body 30, and the second rotation direction S2 is set as the direction in which the rotating cover 40 rotates away from the side of the second box body 30.

[0104] Along the first rotation direction S1, on the surface of the cover portion 42 close to the second box body 30, a first convex portion 43 and a second convex portion 44 are convexly provided. The number of the first convex portions 43 is two. Along the third direction Z, the two first convex portions 43 are spaced apart, and the two first convex portions 43 are respectively provided at the edges of the cover portion 42. In addition, the extending directions of the two first convex portions 43 are the same as the extending directions of the two edges of the cover portion 42 along the third direction Z. A first clamping portion 51 is convexly provided on the end surface of the first convex portion 43 far from the cover portion 42.

[0105] The number of the second convex portions 44 is two, and the two second convex portions 44 are provided between the two first convex portions 43. Along the third direction Z, the two second convex portions 44 are spaced apart, and the two second convex portions 44 are respectively spaced apart from a neighboring first convex portion 43, and a receiving groove 45 is formed between the neighboring first convex portion 43 and the second convex portion 44. The receiving groove 45 is used to receive the portions of the side plates 301 exceeding the back plate 302, so that when the rotating cover 40 closes the demolding opening 32, the portions of the two side plates 301 exceeding the back plate 302 are respectively received in the two receiving grooves 45. In addition, when the portions of the side plates 301 exceeding the back plate 302 are received in the receiving groove 45, the two sides of the side plates 301 in the third direction Z respectively abut against the first convex portion 43 and the second convex portion 44, so as to further improve the connection stability between the rotating cover 40 and the second box body 30.

[0106] Please also combine with Figures 5 to 8 In an embodiment, a clamping groove 510 is provided on the first clamping portion 51, and the clamping groove 510 is used to receive the second clamping portion 52. Along the third direction Z, the clamping groove 510 extends from the side of the first clamping portion 51 far from the second convex portion 44 towards the side of the second convex portion 44 until it penetrates through the second clamping portion 52.

[0107] Wherein, the second clamping portion 52 is located on the rotation path of the first clamping portion 51, and the first clamping portion 51 can rotate to cross over the second clamping portion 52, so that the second clamping portion 52 is clamped in the clamping groove 510.

[0108] Along the third direction Z, the surface of the second clamping portion 52 far from the second box body 30 is provided as a guiding surface P1. Along the first rotation direction S1, the guiding surface P1 extends obliquely from its end close to the rotating cover 40 towards the side far from the second box body 30 to the end of the guiding surface P1 far from the rotating cover 40. The guiding surface P1 is used to abut against the first clamping portion 51 to guide the first clamping portion 51 to rotate to cross over the second clamping portion 52.

[0109] Thus, when the rotating cover 40 rotates along the first rotation direction S1 to a position where the first engaging portion 51 approaches the second engaging portion 52, the guiding surface P1 abuts against the first engaging portion 51 and applies a force along the third direction Z to the first engaging portion 51, thereby pushing the first engaging portion 51 to move along the third direction Z towards the side away from the adjacent side plate 301, so as to ensure that the first engaging portion 51 can smoothly cross over the second engaging portion 52.

[0110] In this embodiment, along the first rotation direction S1, the end surface of the second engaging portion 52 away from the rotating cover 40 is defined as a limiting surface P2. The limiting surface P2 is a plane, and the limiting surface P2 is perpendicular to the side surface of the side plate 301 where the second engaging portion 52 is provided.

[0111] Thus, when the second engaging portion 52 is engaged in the engaging groove 510, the limiting surface P2 abuts against the first engaging portion 51 to limit the rotation of the first engaging portion 51 along the second rotation direction S2, thereby preventing the second engaging portion 52 from disengaging from the engaging groove 510, so as to ensure the stability of the connection between the rotating cover 40 and the second box body 30.

[0112] It can be understood that the limiting surface P2 can also be other shapes such as an inclined surface or a curved surface, and its specific shape is not limited in this application, as long as it is ensured that the setting of the limiting surface P2 can abut against the first engaging portion 51 to prevent it from rotating along the second rotation direction S2.

[0113] It should be noted that in other embodiments, the engaging groove 510 can also be provided on the second engaging portion 52, and the engaging groove 510 is used to receive the first engaging portion 51. During the rotation of the first engaging portion 51 along with the rotating cover 40, the first engaging portion 51 can rotate to be engaged in the engaging groove 510, thereby realizing the engagement between the rotating cover 40 and the second box body 30.
