Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more specifically, to a hinge box assembly, a base assembly, and a vehicle. Background Technology

[0002] Currently, the charging port / fuel filler assembly mainly includes a base, hinge box, hinge, and hinge shaft. During the development of a new vehicle model, when conducting a preliminary feasibility analysis of the charging port / fuel filler assembly, it is usually necessary to first analyze the position of the hinge shaft on the vehicle body, then analyze the arrangement of the hinge and hinge box, and finally determine the opening size of the charging port / fuel filler based on the position of the hinge shaft.

[0003] However, in existing charging port / fuel filler assemblies, the base and hinge box are usually manufactured as a single piece. Since the base is a structure related to the vehicle body shape, it is necessary to re-analyze the placement of the hinge and hinge box for each type of charging port / fuel filler assembly during the initial feasibility analysis. In fact, the hinge and hinge box structure for each vehicle needs to be redesigned. This not only results in a long design cycle, but also poses significant challenges to the design and development of the charging port / fuel filler assembly. Summary of the Invention

[0004] The problem this invention addresses is: how to reduce the design complexity of the charging port / fuel filler assembly.

[0005] To address the aforementioned problems, the present invention provides a hinge box assembly, comprising a hinge box, a hinge, and a hinge shaft. One end of the hinge is housed within the hinge box and is rotatably connected to the hinge box via the hinge shaft. The hinge box is used for detachable connection to a base.

[0006] Optionally, the hinge includes a first hinge arm and a second hinge arm. One end of the first hinge arm is housed within the hinge box and is rotatably connected to the hinge box. The other end of the first hinge arm is connected to the second hinge arm. The second hinge arm is used to connect to the charging port cover or the refueling port cover.

[0007] Optionally, the hinge box includes a first side plate, a second side plate, and a connecting plate. The first side plate and the second side plate are arranged opposite to each other and are respectively connected to both sides of the connecting plate. The first side plate, the second side plate, and the connecting plate together form a box structure with an opening, and the opening is oriented towards the first hinge arm. The first hinge arm is provided with a first hinge hole, and the first side plate and the second side plate are provided with second hinge holes. The first hinge hole and the second hinge hole are coaxially arranged.

[0008] Optionally, the first side plate is provided with a first groove formed by the first side plate being recessed toward the second side plate, and the second side plate is provided with a second groove formed by the second side plate being recessed toward the first side plate, and the second hinge holes on the first side plate and the second side plate are respectively provided in the first groove and the second groove.

[0009] To address the aforementioned problems, the present invention also provides a base assembly, including the hinge box assembly described above.

[0010] Optionally, the base assembly further includes a base with mounting holes, through which the hinge box of the hinge box assembly passes and is detachably connected to the base.

[0011] Optionally, the base is further provided with a first guide structure, and the hinge box body is provided with a second guide structure. The second guide structure is used to cooperate with the first guide structure so that the hinge box moves along a preset motion trajectory when it passes through the mounting hole.

[0012] Optionally, the first guide structure is one of the guide rib and the guide groove, and the second guide structure is the other of the guide rib and the guide groove.

[0013] Optionally, the first guide structure is disposed on the wall of the mounting hole.

[0014] To address the aforementioned problems, the present invention also provides a vehicle comprising the hinge box assembly as described above, or the base assembly as described above.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention allows for the detachable connection of the hinge box and the base, separating the base and hinge box from the charging port / fuel filler assembly. The hinge is then rotatably connected to the hinge box via a hinge shaft to assemble the hinge box assembly. This allows the hinge box assembly to be used as input during the initial feasibility analysis of a new vehicle model, directly positioned on the corresponding location on the vehicle body. When performing motion analysis on the hinge, only minor adjustments to the hinge box assembly's position are needed. Furthermore, once the opening size of the charging port / fuel filler is determined, only the base needs to be redesigned according to different vehicle body shapes, eliminating the need to redesign the entire charging port / fuel filler assembly, effectively reducing its design complexity. Moreover, separating the hinge box assembly from the charging port / fuel filler assembly as a single component facilitates standardized design, improving product consistency and further reducing design complexity. Additionally, during later vehicle assembly, the hinge box assembly can be installed after the base is mounted on the vehicle body, making assembly simpler and more convenient compared to a one-piece base and hinge box.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0027] Combination Figure 1 and Figure 3 As shown, an embodiment of the present invention provides a hinge box assembly 2, including a hinge box 21, a hinge 22 and a hinge shaft 23. One end of the hinge 22 is housed in the hinge box 21 and is rotatably connected to the hinge box 21 through the hinge shaft 23. The hinge box 21 is used for detachable connection with the base 1.

[0028] Specifically, the hinge box 21, hinge 22, and hinge shaft 23 constitute the hinge box assembly 2. The hinge box assembly 2 and the base 1 constitute the base assembly. The hinge box 21 is typically a box structure with a cavity 215. One end of the hinge 22 is housed within the cavity 215 and is rotatably connected to the hinge box 21 via the hinge shaft 23. The portion of the hinge 22 outside the cavity 215 is used to connect to the charging port / fuel filler cap. When the charging port / fuel filler cap is opened, the charging port / fuel filler cap rotates the hinge 22 around the hinge shaft 23. When assembling the base assembly, the hinge and hinge box 21 are typically connected first via the hinge shaft 23, allowing the hinge 22 to rotate around the hinge shaft 23 within a preset angle range. Finally, the assembled hinge box assembly 2 is assembled onto the base 1.

[0029] In this embodiment, the base 1 and hinge box 21 in the charging port / fuel filler assembly can be separated by detachably connecting the hinge box 21 to the base 1. Furthermore, the hinge 22 is rotatably connected to the hinge box 21 through the hinge shaft 23 to assemble the hinge box assembly 2. In this way, during the early feasibility analysis of a new vehicle model, the hinge box assembly 2 can be used as input and directly placed at the corresponding position on the vehicle body. When performing motion analysis on the hinge 22, only the position of the hinge box assembly 2 needs to be finely adjusted. Moreover, after determining the opening size of the charging port / fuel filler, only the base 1 needs to be redesigned according to different vehicle body shapes, without having to redesign the entire charging port / fuel filler assembly, effectively reducing the design difficulty of the charging port / fuel filler assembly. Furthermore, separating the hinge box assembly 2 from the charging port / fuel filler assembly into a single component facilitates the universal design of the hinge box assembly 2, thereby improving product consistency and further reducing the design difficulty of the charging port / fuel filler assembly. In addition, during the later vehicle installation process, the hinge box assembly 2 can be installed after the base 1 is assembled onto the vehicle body, which is simpler and more convenient than the integrated base 1 and hinge box 21.

[0030] Optionally, combined Figure 1 As shown, the hinge 22 includes a first hinge arm 221 and a second hinge arm 222. One end of the first hinge arm 221 is housed in the hinge box 21 and is rotatably connected to the hinge box 21. The other end of the first hinge arm 221 is connected to the second hinge arm 222. The second hinge arm 222 is used to connect to the charging port cover or the refueling port cover.

[0031] Specifically, the first hinge arm 221 and the second hinge arm 222 are usually integrally formed, and the second hinge arm 222 is usually snapped into the charging port cover or the refueling port cover.

[0032] In this embodiment, the first hinge arm 221 and the second hinge arm 222 are typically integrally formed. The first hinge arm 221 is housed within the cavity 215 of the hinge box 21 and is rotatably connected to the hinge box 21 via the hinge shaft 23. The second hinge arm 222 is located outside the cavity 215 and is used to form a detachable connection with the charging port cover or the fuel filler cap using a snap-fit ​​method. This achieves connection between the hinge 22 and the hinge box 21, and between the hinge 22 and the charging port cover or the fuel filler cap, and the structure is simple and easy to manufacture.

[0033] Furthermore, the first hinge arm 221 is fitted with the inner wall of the hinge box 21 with a clearance fit. This prevents the first hinge arm 221 from interfering with the hinge box 21 when rotating around the hinge axis 23, thereby ensuring the smoothness of the hinge 22's rotation.

[0034] Optionally, combined Figure 2 and Figure 4 As shown, the hinge box 21 includes a first side plate 211, a second side plate 212, and a connecting plate 213. The first side plate 211 and the second side plate 212 are arranged opposite to each other and are respectively connected to both sides of the connecting plate 213. The first side plate 211, the second side plate 212, and the connecting plate 213 enclose a box structure with an opening, and the opening is arranged facing the first hinge arm 221. The first hinge arm 221 is provided with a first hinge hole, and the first side plate 211 and the second side plate 212 are provided with second hinge holes. The first hinge hole and the second hinge hole are coaxially arranged.

[0035] In this embodiment, by providing a first hinge hole on the first hinge arm 221 and a second hinge hole on the first side plate 211 and the second side plate 212, during assembly, the first hinge arm 221 can be inserted into the cavity 215 first, and the first hinge hole can be aligned with the second hinge hole. Then, the hinge shaft 23 can be inserted into the first hinge hole and the second hinge hole, thus realizing the rotational connection between the hinge 22 and the hinge box 21. Moreover, the assembly process is simple and convenient. At the same time, the hinge box 21 has a box structure with an opening formed by the first side plate 211, the second side plate 212 and the connecting plate 213, and the opening is set towards the first hinge arm 221, so that the first hinge arm 221 and the hinge shaft 23 form a rotational connection within the cavity 215 surrounded by the hinge box 21, thereby providing protection for the hinge shaft 23 and the first hinge arm 221.

[0036] Optionally, combined Figure 2 and Figure 4 As shown, the first side plate 211 is provided with a first groove 2111 formed by the first side plate 211 recessed toward the second side plate 212, and the second side plate 212 is provided with a second groove formed by the second side plate 212 recessed toward the first side plate 211. The second hinge holes on the first side plate 211 and the second side plate 212 are respectively provided in the first groove 2111 and the second groove.

[0037] Since the hinge shaft 23 is inserted through the first hinge hole and the second hinge hole, the two ends of the hinge shaft 23 usually extend from the second hinge hole on the first side plate 211 and the second side plate 212 to the outside of the hinge box 21, in order to avoid the part of the hinge shaft 23 extending out of the hinge box 21 from interfering with other components, in this embodiment, a first groove 2111 and a second groove are respectively provided on the first side plate 211 and the second side plate 212, and the second hinge hole on the first side plate 211 and the second side plate 212 is respectively provided in the first groove 2111 and the second groove, so that the first side plate 211 and the second side plate 212 form a recess at the second hinge hole, so as to ensure that the two ends of the hinge shaft 23 can be accommodated in the first groove 2111 and the second groove respectively while extending out of the second hinge hole, thereby avoiding interference between the hinge shaft 23 and other components. At the same time, the length of the hinge shaft 23 can be shortened and the space occupied by the hinge shaft 23 can be reduced.

[0038] Combination Figure 3 As shown, another embodiment of the present invention provides a base assembly including the hinge box assembly 2 as described above.

[0039] The beneficial effects of the base assembly in this embodiment compared to the prior art are the same as those of the hinge box assembly 2 described above, and will not be repeated here.

[0040] Optionally, combined Figure 4 and Figure 5 As shown, the base assembly also includes a base 1, which has a mounting hole 11. The hinge box 21 of the hinge box assembly 2 passes through the mounting hole 11 and is detachably connected to the base 1.

[0041] In this embodiment, the base 1 typically has a cavity structure with a through hole, and mounting holes 11 are provided on the cavity wall of the cavity structure. During assembly, the hinge box 21 of the hinge box assembly 2 moves along... Figure 4 The direction indicated by the dashed arrow passes through the mounting hole 11. Specifically, the hinge box 21 of the assembled hinge box assembly 2 is usually inserted into the base 1 through the through hole at the end facing the charging port / fuel filler cap, and then passes through the mounting hole 11 to exit the base 1. The hinge box 21 and the base 1 are then connected by a detachable method such as snap-fit, thus realizing the assembly of the base assembly. The operation is simple and convenient.

[0042] Optionally, combined Figure 6 As shown, the base 1 is also provided with a first guide structure 12, and the hinge box 21 is provided with a second guide structure 214. The first guide structure 12 is used to cooperate with the second guide structure 214 so that the hinge box 21 moves along a preset trajectory when it passes through the mounting hole 11.

[0043] In this way, when the hinge box assembly 2 is assembled onto the base 1, the installation of the hinge box assembly 2 can be guided and limited, ensuring that the hinge box 21 passes through the mounting hole 11 of the base 1 along the preset trajectory, making the assembly process simpler and more convenient.

[0044] Optionally, combined Figure 6 As shown, the first guide structure 12 is one of the guide rib and the guide groove, and the second guide structure 214 is the other of the guide rib and the guide groove.

[0045] Specifically, guide ribs can be provided on the first side plate 211 and / or the second side plate 212 of the hinge box 21, and guide grooves can be provided on the base 1; alternatively, guide grooves can be provided on the first side plate 211 and / or the second side plate 212, and guide ribs can be provided on the base 1. However, regardless of whether guide ribs or guide grooves are provided on the hinge box 21, the guide ribs or guide grooves must match the movement trajectory of the hinge box 21 as it passes through the mounting hole 11. That is, when the hinge box 21 passes through the mounting hole 11 of the base 1 along an arc-shaped trajectory, the guide ribs or guide grooves are also arc-shaped.

[0046] This configuration simplifies the structure of the first guide structure 12 and the second guide structure 214, making them easier to manufacture. It also allows for minor modifications to the original structure of the hinge box 21, thereby reducing the cost of redesigning the hinge box 21.

[0047] Optionally, combined Figure 5 As shown, the first guide structure 12 is disposed on the wall of the mounting hole 11.

[0048] Specifically, Figure 5 The example given is a guide groove on the wall of the mounting hole 11. When a guide groove is opened on the wall of the mounting hole 11, it is equivalent to opening a notch structure on the edge of the mounting hole 11.

[0049] In this embodiment, a guide structure, such as a guide rib or a guide groove, can be provided on the wall of the mounting hole 11 to prevent the first guide structure 12, which is a guide rib, from protruding from the inner or outer surface of the base 1, or to prevent the first guide structure 12, which is a guide groove, from being opened on the cavity wall of the base 1, thus reducing the structural strength of the base 1. Moreover, after assembly, the first guide structure 12 can be covered by the hinge box 21, so that when the first guide structure 12 is a guide rib, it will not affect the assembly of other parts that need to be installed on the base 1.

[0050] Another embodiment of the present invention provides a vehicle including the hinge box assembly 2 as described above or the base assembly as described above.

[0051] The beneficial effects of the vehicle in this embodiment compared to the prior art are the same as those of the hinge box assembly 2 or the base assembly described above, and will not be repeated here.

[0052] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
