Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a hinge structure, a tool box and a vehicle. Background Art

[0002] To facilitate simple repairs on commercial vehicles, toolboxes are often installed. These are located behind the cab's side doors and are used to store onboard tools. Currently, most toolboxes on the market feature flip-up lids supported and held in place by gas springs. Side-opening toolboxes, however, lack gas springs and rely solely on hinges for position control. While hinged structures employ friction to achieve position control, these designs are less durable and, over time, wear out, weakening the retaining force, resulting in poor retention effectiveness.

[0003] Therefore, a hinge structure, a tool box and a vehicle are needed to solve the above problems. Summary of the Invention

[0004] The object of the present invention is to provide a hinge structure, a tool box and a vehicle, which can ensure a limiting effect.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] Hinge structure, including:

[0007] a fixed blade connected to the body-in-white;

[0008] a hinge arm, the hinge arm being arc-shaped, the first end of the hinge arm being rotatably connected to the first end of the fixed blade, the hinge arm extending toward the second end of the fixed blade, and the second end of the hinge arm being connected to the tool box cover;

[0009] an elastic limiting member, the elastic limiting member being arranged at the second end of the fixed blade and abutting against the hinge arm;

[0010] A positioning assembly is provided on the hinge arm, and the elastic limiting member can cooperate with the positioning assembly to limit the opening angle of the tool box cover relative to the body-in-white.

[0011] In some embodiments, a rotating shaft is fixedly provided on the first end of the fixed blade, and the first end of the hinge arm is rotatably sleeved on the rotating shaft.

[0012] In some embodiments, the positioning assembly includes a plurality of first positioning protrusions, and the plurality of first positioning protrusions are arranged at intervals on the hinge arm.

[0013] In some embodiments, the positioning assembly includes a second positioning protrusion, which is arranged on the hinge arm, and the second positioning protrusion is closer to the second end of the hinge arm than the first positioning protrusion. The elastic limiter can cooperate with the second positioning protrusion to keep the tool box cover in a closed state.

[0014] In some embodiments, the positioning assembly includes a third positioning protrusion, which is arranged on the hinge arm, and the third positioning protrusion is closer to the first end of the hinge arm than the first positioning protrusion. The elastic limiter can cooperate with the third positioning protrusion so that the tool box cover is in a fully open state.

[0015] In some embodiments, the elastic limiter includes a fixing portion and a guide portion connected to each other, the fixing portion is connected to the second end of the fixed blade, and the fixing portion abuts against the hinge arm, and the guide portion is set at an obtuse angle to the fixing portion.

[0016] In some embodiments, the fixing portion and the guiding portion are an integrated structure.

[0017] In some embodiments, a sealing sleeve is further included, which is mounted on the second end of the hinge arm and is located in the gap between the tool box cover and the body in white. When the tool box cover is in a closed state, the sealing sleeve abuts against the body in white to seal the gap.

[0018] A tool box comprises a tool box cover and the hinge structure as described above, wherein the hinge structure is connected to the tool box cover and the body in white.

[0019] A vehicle comprises a vehicle body and the tool box as described above, wherein the tool box is arranged on the vehicle body.

[0030] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0031] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0032] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0033] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0034] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0035] In order to ensure that the tool box cover of the vehicle can be effectively limited during opening or closing, such as Figure 1-Figure 3 As shown, the present invention provides a hinge structure, which includes a fixed blade 1, a hinge arm 2, an elastic limiter 3 and a positioning assembly.

[0036] The fixed vane 1 is connected to the vehicle body in white (BIW) 100. A hinge arm 2 is arc-shaped, with its first end pivotally connected to the first end of the fixed vane 1. The hinge arm 2 extends toward the second end of the fixed vane 1, and its second end is connected to the tool box cover 200. An elastic stopper 3 is disposed at the second end of the fixed vane 1 and abuts against the hinge arm 2. A positioning assembly is disposed on the hinge arm 2, and the elastic stopper 3 cooperates with the positioning assembly to limit the opening angle of the tool box cover 200 relative to the vehicle body in white (BIW) 100.

[0037] Because the elastic stopper 3 abuts the hinge arm 2, the frictional engagement between the elastic stopper 3 and the hinge arm 2 effectively acts as a limiter, allowing the tool box cover 200 to hover. Furthermore, the elastic stopper 3 and the hinge arm 2 elastically abut, ensuring a positive limiter effect. The elastic stopper 3 cooperates with the positioning assembly to define the opening angle of the tool box cover 200 relative to the vehicle body 100, further limiting the tool box cover 200 and reducing wear on the elastic stopper 3.

[0038] In some embodiments, a rotating shaft 11 is fixedly mounted on the first end of the fixed blade 1, and the first end of the hinge arm 2 is rotatably mounted on the rotating shaft 11. The provision of the rotating shaft 11 facilitates the mating installation of the hinge arm 2 and the fixed blade 1, and ensures effective rotation of the hinge arm 2 relative to the fixed blade 1. In other embodiments, the rotating shaft 11 may be fixedly mounted on the hinge arm 2, and the first end of the fixed blade 1 is rotatably mounted on the rotating shaft 11, without further limitation.

[0039] In some embodiments, the positioning assembly includes a plurality of first positioning protrusions 21 spaced apart on the hinge arm 2. Optionally, the first positioning protrusions 21 are arched, facilitating movement of the first positioning protrusions 21 relative to the elastic stopper 3 during rotation of the toolbox lid 200. During rotation of the toolbox lid 200, the elastic stopper 3 engages with the first positioning protrusions 21 at different positions, thereby defining the opening angle of the toolbox lid 200.

[0040] In some embodiments, the positioning assembly includes a second positioning protrusion 22, which is disposed on the hinge arm 2 and is closer to the second end of the hinge arm 2 than the first positioning protrusion 21. The elastic stopper 3 can cooperate with the second positioning protrusion 22 to keep the tool box lid 200 in the closed state. Due to the cooperation between the elastic stopper 3 and the second positioning protrusion 22, when the tool box lid 200 is in the closed state, even after being unlocked, the tool box lid 200 will not automatically open. External force is required to open it, thus preventing safety hazards caused by accidental opening of the tool box.

[0041] In some embodiments, the positioning assembly includes a third positioning protrusion 23, which is disposed on the hinge arm 2 and is closer to the first end of the hinge arm 2 than the first positioning protrusion 21. The elastic stopper 3 can cooperate with the third positioning protrusion 23 to maintain the tool box lid 200 in a fully open state. With this arrangement, when the tool box lid 200 needs to be fully opened, the elastic stopper 3 cooperates with the third positioning protrusion 23 to maintain the tool box lid 200 in a stable, fully open state.

[0042] In some embodiments, the elastic stopper 3 includes a fixed portion 31 and a guide portion 32 that are interconnected. The fixed portion 31 is connected to the second end of the fixed blade 1 and abuts the hinge arm 2. The guide portion 32 is arranged at an obtuse angle to the fixed portion 31. The provision of the fixed portion 31 facilitates the connection of the elastic stopper 3 to the fixed blade 1. The provision of the guide portion 32 prevents the elastic stopper 3 from getting stuck when moving relative to the first positioning protrusion 21, the second positioning protrusion 22, and the third positioning protrusion 23, thereby ensuring the flexible rotation of the tool box cover 200.

[0043] In some embodiments, the fixing portion 31 and the guide portion 32 are an integrated structure. Specifically, the fixing portion 31 and the guide portion 32 can be integrally formed using a sheet metal process, which ensures a stable connection between the fixing portion 31 and the guide portion 32 while reducing manufacturing difficulty.

[0044] In some embodiments, the hinge structure further includes a sealing sheath 4, which is fixedly mounted on the second end of the hinge arm 2 and positioned in the gap between the toolbox lid 200 and the body-in-white 100. When the toolbox lid 200 is closed, the sealing sheath 4 abuts the body-in-white 100 to seal the gap. In the prior art, toolbox hinges are often built-in, embedded within the body-in-white 100. To save space, toolbox hinges are often placed outside the toolbox sealing strip, resulting in air and rain leaks and poor sealing performance. In this embodiment, by placing the sealing sheath 4 in this manner, the gap in the hinge structure can be effectively sealed, thereby preventing rainwater from flowing into the toolbox.

[0045] The present application also provides a toolbox, which includes a toolbox cover 200 and the above hinge structure. The hinge structure is connected to the toolbox cover 200 and the body-in-white 100, and can ensure the limiting effect after the toolbox cover 200 is opened.

[0046] The present application also provides a vehicle, which includes a vehicle body and a toolbox as described above. The toolbox is arranged on the vehicle body, which can ensure the limiting effect of the toolbox cover 200 after opening the toolbox.

[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
