[0041] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0042] Reference will be made below Figures 1 - 13 to describe the hinge structure 100 according to an embodiment of the present utility model. The hinge structure 100 can increase the opening height of the hinge structure 100, and has a simple and compact overall structure, is easy to install and maintain, reduces the manufacturing cost and the usage cost, and improves the opening and closing efficiency of the components.

[0043] As Figures 1 - 13 shown, the hinge structure 100 according to an embodiment of the present utility model includes: a rotating arm 1, a lifting arm 2, a fork arm assembly 5, and a fixed seat 6.

[0044] The rotating arm 1 can be connected to other components. When the other components need to adjust their angles or directions during movement, it drives the rotating arm 1 to move. Then, through the rotational movement of the rotating arm 1, the direction or angle of the components connected thereto is adjusted, and finally the angle or direction of the other components is adjusted.

[0045] The lifting arm 2 is movably connected to the rotating arm 1 through a first connecting rod 3 and a second connecting rod 4 and together form a four-bar linkage.

[0046] Specifically, the lifting arm 2 is used to achieve vertical movement, that is, lifting movement. And the lifting arm 2 is connected to the rotating arm 1 through the first connecting rod 3 and the second connecting rod 4 to form a four-bar linkage. When the rotating arm 1 moves, through the interaction between the connecting rods, the lifting arm 2 can be kept stable during the lifting process. At the same time, the first connecting rod 3 and the second connecting rod 4 rotate to drive the lifting arm 2 to move, so as to transfer the rotational movement of the rotating arm 1 to the lifting arm 2 and realize the coordinated movement of the rotating arm 1 and the lifting arm 2.

[0047] Furthermore, the fork arm assembly 5 includes a first fork arm 51 and a second fork arm 52. The first fork arm 51 and the second fork arm 52 are cross-distributed and rotatably connected. The lifting arm 2 is movably connected to the fixed seat 6 through the first fork arm 51 and the second fork arm 52 and can be lifted relative to the fixed seat 6.

[0048] Specifically, the fixed seat 6 is the support foundation of the entire hinge structure 100. The fixed seat 6 can be fixedly connected to another component to provide stable support for the entire structure. For example, it can be connected by welding, bolt connection, etc., so as to provide stable mounting connection points for components such as the fork arm assembly 5 and the lifting arm 2, ensuring the stability and reliability of the entire hinge structure 100, and enabling components such as the fork arm assembly 5 and the lifting arm 2 to move stably. Among them, the first fork arm 51 and the second fork arm 52 are cross-distributed and can be rotatably connected by a pin shaft, a rotating shaft, etc., that is, relative movement can occur between the first fork arm 51 and the second fork arm 52, and the first fork arm 51 and the second fork arm 52 are connected to the lifting arm 2. In this way, the lifting arm 2 can be lifted and lowered relative to the fixed seat 6 through the movement of the first fork arm 51 and the second fork arm 52, which is flexible and reliable.

[0049] In practice, when the lifting arm 2 rises relative to the fixed seat 6, the height of the rotating arm 1 relative to the fixed seat 6 also rises. The hinge structure 100 can be used to increase the opening height of other components. When the lifting arm 2 descends relative to the fixed seat 6, the height of the rotating arm 1 relative to the fixed seat 6 also descends. At this time, the hinge structure 100 can be used to close other components.

[0050] In addition, the cross-distribution setting of the first fork arm 51 and the second fork arm 52 can improve the movement stability of the lifting arm 2, reduce its lateral offset during the lifting process, and also ensure the stable movement of the first fork arm 51 and the second fork arm 52.

[0051] Therefore, through the connection design of the four-bar linkage mechanism with the fork arm assembly 5 and the fixed seat 6, the motion transfer from the rotating arm 1 to the fork arm assembly 5 is realized, and then the flexible rotation of the rotating arm 1 relative to the fixed seat 6 is realized. The lifting arm 2 is connected to the fixed seat 6 through the first fork arm 51 and the second fork arm 52, so that during the movement of the hinge structure 100, the lifting arm 2 can be lifted and lowered relative to the fixed seat 6, thereby increasing the height of the rotating arm 1 relative to the fixed seat 6. Thus, when using the hinge structure 100 to open a component, the opening height of the component can be increased, avoiding interference with other surrounding related components of the component due to too low opening height.

[0052] It should be noted that the hinge structure 100 of this embodiment can be applied to any component that needs to realize opening and closing with the functions of rotation and lifting together. For example, it can be applied to furniture door panels, engine hoods of vehicles, etc.

[0053] According to the hinge structure 100 of the embodiments of the present utility model, through the connection design of the four-bar mechanism with the fork arm assembly 5 and the fixed seat 6, the flexible rotation of the rotating arm 1 relative to the fixed seat 6 is realized, and the lifting arm 2 is connected to the fixed seat 6 through the first fork arm 51 and the second fork arm 52, so that during the movement of the hinge structure 100, the lifting arm 2 can move up and down relative to the fixed seat 6, thereby increasing the height of the rotating arm 1 relative to the fixed seat 6, further increasing the opening height of the hinge structure 100, and the overall structure is simple, compact, easy to install and maintain, reducing the manufacturing cost and use cost, and improving the opening and closing efficiency of the components.

[0054] In some embodiments, the fixed seat 6 is provided with a first sliding portion, a second sliding portion and a third sliding portion, and the lifting arm 2 is provided with a fourth sliding portion. One end of the first fork arm 51 is rotatably connected to the fixed seat 6, and the other end of the first fork arm 51 can slide along the first sliding portion and can also slide along the fourth sliding portion. One end of the second fork arm 52 can slide along the second sliding portion, and the other end of the second fork arm 52 can slide along the third sliding portion.

[0055] Specifically, one end of the first fork arm 51 can be connected to the fixed seat 6 through a rotating shaft, a pin shaft, etc. The first sliding portion and the fourth sliding portion are used to provide a sliding path for the other end of the first fork arm 51. The first sliding portion and the fourth sliding portion can be grooves, slide rails, etc. The direction of the first sliding portion can be set to be different from the direction of the fourth sliding portion to form a sliding fit, so that the other end of the first fork arm 51 can slide flexibly along the first sliding portion and the fourth sliding portion at the same time. In this way, when one end of the first fork arm 51 can rotate flexibly relative to the fixed seat 6, the other end of the first fork arm 51 can slide flexibly along the first sliding portion and the fourth sliding portion at the same time, thereby realizing the up and down movement of the lifting arm 2.

[0056] The second sliding portion is used to provide a sliding path for one end of the second fork arm 52, and the third sliding portion is used to provide a sliding path for the other end of the second fork arm 52. The second sliding portion and the third sliding portion can be grooves, slide rails, etc. The direction of the second sliding portion can be set to be the same or different from the direction of the third sliding portion. In this way, one end of the second fork arm 52 can slide flexibly along the second sliding portion, and the other end of the second fork arm 52 can slide flexibly along the third sliding portion, so that both ends of the second fork arm 52 can slide at the same time, and further the up and down movement of the lifting arm 2 can be realized.

[0057] In practice, when the rotating arm 1 starts to rotate, it drives the first link 3 and the second link 4 to rotate. Through the transmission of the first link 3 and the second link 4, the lifting arm 2 starts to rise and fall. When the lifting arm 2 rises and falls, one end of the first fork arm 51 can rotate relative to the fixed seat 6, and the other end slides along the first sliding part and the fourth sliding part at the same time. At the same time, one end of the second fork arm 52 slides along the second sliding part, and the other end slides along the third sliding part. Thus, through the mutual cooperation of the fork arm assembly 5 and each sliding part, the hinge structure 100 can realize the stable lifting of the lifting arm 2 and the rotational movement of the rotating arm 1 under the rotational drive of the rotating arm 1, and further realize the increase of the opening height.

[0058] In some embodiments, the first sliding part and the third sliding part are spaced apart and oppositely distributed in the first direction, and both the first sliding part and the third sliding part extend in the second direction.

[0059] Specifically, the first direction and the second direction can be relative directions such as the up-down direction, the left-right direction, etc. The first direction can intersect or be perpendicular to the second direction. As Figure 2 and Figure 6 shown, the first direction is the left-right direction shown in the figure, and the second direction is the up-down direction shown in the figure. That is, the first sliding part and the third sliding part are spaced apart and oppositely distributed in the left-right direction. The first sliding part is close to the right end position of the fixed seat 6, and the first sliding part extends in the up-down direction. The second sliding part is close to the left end position of the fixed seat 6, and the second sliding part extends in the up-down direction.

[0060] Thus, the right end of the first fork arm 51 can slide up and down along the first sliding part, and the left end of the second fork arm 52 can slide up and down along the third sliding part. Thus, the first fork arm 51 and the second fork arm 52 can slide up and down following the lifting and lowering of the lifting arm 2, which is beneficial to realizing the stable movement of the lifting arm 2.

[0061] The second sliding part and the fourth sliding part are spaced apart and oppositely distributed in the second direction, and both the second sliding part and the fourth sliding part extend in the first direction.

[0062] As Figure 2 and Figure 6 shown, the first direction is the left-right direction shown in the figure, and the second direction is the up-down direction shown in the figure. That is, the second sliding part and the fourth sliding part are spaced apart and oppositely distributed in the up-down direction. The second sliding part is close to the lower end position of the fixed seat 6 and is located below the first sliding part, and the second sliding part extends in the left-right direction. The fourth sliding part is close to the lower right end position of the lifting arm 2, and the fourth sliding part extends in the left-right direction.

[0063] Thus, when the right end of the first fork arm 51 slides up and down along the first sliding portion, it can simultaneously slide left and right along the fourth sliding portion. When the left end of the second fork arm 52 slides up and down along the third sliding portion, its right end can slide left and right along the second sliding portion. As a result, the first fork arm 51 and the second fork arm 52 can slide flexibly following the lifting and lowering of the lifting arm 2, thereby achieving stable movement of the lifting arm 2.

[0064] In addition, the first sliding portion, the second sliding portion, and the third sliding portion are dispersedly arranged on the fixed seat 6, which not only provides stable support and guidance for the fork arm assembly 5, but also enables the fork arm assembly 5 to slide smoothly along a predetermined trajectory during the lifting and rotating processes, reducing shaking. Moreover, it enhances the stability and structural strength of the hinge structure 100, making the structure compact.

[0065] In some embodiments, the first sliding portion is configured as a first sliding groove 61, the fourth sliding portion is configured as a fourth sliding groove 22, and one end of the first fork arm 51 is provided with a first rotating shaft. Among them, one end of the first fork arm 51 extends between the lifting arm 2 and the fixed seat 6, and one end of the first rotating shaft slides in the first sliding groove 61, and the other end of the first rotating shaft slides in the fourth sliding groove 22.

[0066] Specifically, as Figure 6 shown, a groove, namely the first sliding groove 61, is formed at the right end position of the fixed seat 6. The first sliding groove 61 extends obliquely in the up and down direction, and its width is adapted to the first fork arm 51 to facilitate the smooth sliding of the first fork arm 51. As Figure 8 shown, a groove, namely the fourth sliding groove 22, is formed at the lower right end position of the lifting arm 2. The right end of the first fork arm 51 is provided with a first rotating shaft. The right end of the first fork arm 51 extends between the lifting arm 2 and the fixed seat 6. One end of the first rotating shaft facing the fixed seat 6 slides in the first sliding groove 61, and one end of the first rotating shaft facing the lifting arm 2 slides in the fourth sliding groove.

[0067] Thus, the first fork arm 51 is rotationally connected to the lifting arm 2 and the fixed seat 6 through the first rotating shaft, enabling the first fork arm 51 not only to rotate relative to the fixed seat 6 and the lifting arm 2, but also to slide along the first sliding groove 61 and the second sliding groove 62 simultaneously. In this way, when the lifting arm 2 is lifted or lowered, it can drive the first fork arm 51 to slide in the two sliding grooves through the first rotating shaft, simultaneously realizing the combined movement of rotation and lifting of the first fork arm 51.

[0068] In some embodiments, the second sliding portion is configured as a second sliding groove 62, one end of the second fork arm 52 is provided with a second rotating shaft, and one end of the second rotating shaft slides in the second sliding groove 62.

[0069] Specifically, as Figure 6As shown, a groove is provided at the lower right end of the fixed seat 6, namely the second sliding groove 62. The second sliding groove 62 extends in the left - right direction, and its width is adapted to the second fork arm 52 to facilitate the smooth sliding of the second fork arm 52. A second rotating shaft is provided at the right end of the second fork arm 52. One end of the second rotating shaft facing the fixed seat 6 slides in the second sliding groove 62. Thus, the right end of the second fork arm 52 can achieve relative rotation with the fixed seat 6 through the second rotating shaft. At the same time, the right end of the second fork arm 52 can also slide in the second sliding groove 62 through the second rotating shaft.

[0070] In some embodiments, the third sliding part is configured as a third sliding groove 63. The other end of the second fork arm 52 is provided with a third rotating shaft, and the lifting arm 2 is provided with a protruding connecting part 21 (connector 121). Among them, the protruding connecting part 21 (connector 121) extends between the other end of the second fork arm 52 and the fixed seat 6, and the third rotating shaft is rotatably passed through the protruding connecting part 21 (connector 121), and one end of the third rotating shaft slides in the third sliding groove 63.

[0071] Specifically, as Figure 6 shown, a groove is provided at the left end position of the fixed seat 6, namely the third sliding groove 63. The third sliding groove 63 extends in the up - down direction, and its width is adapted to the second fork arm 52 to facilitate the smooth sliding of the second fork arm 52. As Figure 8 shown, the left lower end of the lifting arm 2 protrudes to form a protruding connecting part 21. The protruding connecting part 21 is used to connect the second fork arm 52, and the upper part of the protruding connecting part 21 is used to avoid the first connecting rod 3, so that the first connecting rod 3 can rotate flexibly and avoid interference with the second fork arm 52.

[0072] Among them, a third rotating shaft is provided at the left end of the second fork arm 52, a through - hole is provided on the protruding connecting part 21, the protruding connecting part 21 extends between the left end of the second fork arm 52 and the fixed seat 6, and one end of the third rotating shaft facing the fixed seat 6 passes through the through - hole and slides in the third sliding groove 63. Thus, the left end of the second fork arm 52 can achieve relative rotation with the fixed seat 6 and the lifting arm 2 through the third rotating shaft. At the same time, the left end of the second fork arm 52 can also slide in the third sliding groove 63 through the third rotating shaft.

[0073] Thus, the two ends of the second fork arm 52 are rotationally connected to the lifting arm 2 and the fixed seat 6 through the second rotating shaft and the third rotating shaft, realizing the compound movement of rotation and lifting of the second fork arm 52.

[0074] In some embodiments, the fixed seat 6 is configured as a plate - like member. The lifting arm 2 and the fork arm assembly 5 are both located on the same side of the fixed seat 6, and the lifting arm 2 is connected above the fork arm assembly 5.

[0075] Specifically, as Figure 6As shown, the fixed seat 6 is configured as a square plate-like member, which has a relatively large area and a certain thickness, can increase the contact connection area with other components, thereby ensuring the installation stability and reliability of the fixed seat 6, and can provide a relatively large support installation surface for the fork arm assembly 5 and the lifting arm 2, which is conducive to installing the lifting arm 2, the fork arm assembly 5 and other components.

[0076] As Figure 2 shown, the lifting arm 2 and the fork arm assembly 5 are located on the upper side of the fixed seat 6, which is conducive to simplifying the structure and making the structure more compact, and the lifting arm 2 is connected above the fork arm assembly 5, so that when the lifting arm 2 moves in the up and down directions, it can drive the fork arm assembly 5 to perform corresponding sliding movements.

[0077] In some embodiments, the rotating arm 1 is connected above the lifting arm 2 through the first connecting rod 3 and the second connecting rod 4.

[0078] Specifically, as Figure 9 shown, the first connecting rod 3 is configured as a rod bent upward, and the surface of the first connecting rod 3 is flat. As Figure 10 and 11 shown, the second connecting rod 4 is configured as a slightly bent rod, and the middle part of the second connecting rod 4 protrudes to form a middle strengthening structure. In this way, it can provide additional support and guidance for the rotating arm 1, which is conducive to the first connecting rod 3 and the second connecting rod 4 to transmit the force or torque from the rotating arm 1, so that the first connecting rod 3 and the second connecting rod 4 can rotate at a certain angle, and finally enable other components to be opened at a certain angle. At the same time, it can improve the strength of the two connecting rods to a certain extent and prevent the first connecting rod 3 and the second connecting rod 4 from deforming, breaking, etc.

[0079] As Figure 2 and Figure 8 shown, the lifting arm 2 can also be configured as a plate-like member with a protruding connecting portion 21 protruding from the lower left end. The lower ends of the first connecting rod 3 and the second connecting rod 4 are connected to the upper end of the lifting arm 2, and the upper ends of the first connecting rod 3 and the second connecting rod 4 are connected to the left end of the rotating arm 1. Thus, the rotating arm 1 is connected above the lifting arm 2 through the first connecting rod 3 and the second connecting rod 4, and a stable four-bar linkage mechanism is formed, which can transmit the movement of the rotating arm 1 to the lifting arm 2 through the first connecting rod 3 and the second connecting rod 4, realizing the conversion of the rotational movement of the rotating arm 1 into the linear lifting movement of the lifting arm 2, and finally improving the opening height of other components.

[0080] Among them, it should be noted that the opening angle for other components can be adjusted by adjusting the lengths, shapes of the first link 3 and the second link 4, and the distance between the two links. The opening height for other components can be adjusted by adjusting the height of the lifting arm 2 and the lengths of the first sliding groove 61 and the third sliding groove 63. It can be understood that the higher the height of the lifting arm 2, or the longer the lengths of the first sliding groove 61 and the third sliding groove 63, the higher the opening height.

[0081] In some embodiments, the rotating arm 1 includes a mounting plate 11 and a connecting plate 12. The mounting plate 11 is bent and connected to the connecting plate 12. The first link 3 and the second link 4 are respectively rotatably connected to the mounting plate 11. The connecting plate 12 is formed with a connecting portion 121.

[0082] Specifically, as Figure 12 shown, the rotating arm 1 includes a mounting plate 11 and a connecting plate 12. The mounting plate 11 and the connecting plate 12 are bent and connected to form an integral rotating arm 1, so that the cross-section of the rotating arm 1 is "L"-shaped. The mounting plate 11 is used to be fitted and connected to the component to be opened. For example, it can be connected by bolts, welding, etc. The connecting plate 12 is used to connect to the first link 3 and the second link 4, so that the rotating arm 1 can perform relative movement with the first link 3 and the second link 4, and the structure is simple and reliable.

[0083] Among them, a connecting portion 121 is formed on the connecting plate 12. The connecting portion 121 is configured as a connecting hole. Corresponding holes are provided on the first link 3 and the second link 4 corresponding to the connecting hole. Thus, the connecting member can pass through the first link 3 and the connecting plate 12 in sequence, or the second link 4 and the connecting plate 12, so as to rotatably connect the first link 3 and the second link 4 to the mounting plate 11 respectively, and realize the relative rotation between the first link 3 and the second link 4 and the mounting plate 11.

[0084] The present utility model also proposes a vehicle.

[0085] The vehicle according to the embodiment of the present utility model includes a vehicle body, an engine hood 200, and the hinge structure 100 of any one of the above embodiments. The rotating arm 1 is connected to the engine hood 200, and the fixed seat 6 is connected to the vehicle body.

[0086] Specifically, mounting holes 111 are provided on the mounting plate 11. The rotating arm 1 can be bolt-connected to the engine hood 200 by passing bolts through the mounting holes 111, which is flexible and convenient. Of course, welding connection can also be performed. The fixed seat 6 can also be connected to the vehicle body by bolt connection, welding connection, etc.

[0087] Thus, when the engine hood 200 needs to be opened, the engine hood 200 can be driven by the rotating arm 1 to rotate by a certain angle, so as to realize the opening of the engine hood 200. And the upward movement of the lifting arm 2 can increase the opening height of the rear corner of the engine hood, that is, the rear corner of the engine hood is higher than the surface of the engine hood in the closed state when in the open state, so as to avoid interference between the rear corner of the engine hood and the surrounding components when entering the engine compartment.

[0088] For the vehicle according to the embodiment of the present invention, through the connection design of the four-bar linkage mechanism with the fork arm assembly 5 and the fixed seat 6, the flexible rotation of the rotating arm 1 relative to the fixed seat 6 is realized. And the lifting arm 2 is connected to the fixed seat 6 through the first fork arm 51 and the second fork arm 52, so that during the movement of the hinge structure 100, the lifting arm 2 can move up and down relative to the fixed seat 6, thereby increasing the height of the rotating arm 1 relative to the fixed seat 6, further increasing the opening height of the hinge structure 100, avoiding interference between the rear corner of the engine hood 200 and the surrounding components when entering the engine compartment, and the overall structure is simple and compact, easy to install and maintain, reducing the manufacturing cost and the use cost, and improving the opening and closing efficiency of the engine hood 200.
