[0033] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0034] Reference below Figure 1-Figure 6 The hinge structure 10 according to the embodiment of the present invention is described, including: a fixing base 100 , a first connecting rod 200 , a second connecting rod 300 and a rotating arm 400 .

[0035] Specifically, the fixed seat 100 is used to connect with the vehicle body frame, and a first seat limiting portion 510 is provided on the fixed seat 100; one end of the first connecting rod 200 is rotatably connected to the fixed seat 100; one end of the second connecting rod 300 is rotatably connected to the fixed seat 100, and the second connecting rod 300 is located behind the first connecting rod 200, and one of the first connecting rod 200 and the second connecting rod 300 is provided with a first rod limiting portion 610; the rotating arm 400 is used to connect with the engine hood, and the other end of the first connecting rod 200 and the other end of the second connecting rod 300 are connected to the rotating arm 400 at an interval, and an arm limiting portion 410 is provided on the rotating arm 400, and the arm limiting portion 410 is located in front of the first seat limiting portion 510; when the engine hood is closed, the first rod limiting portion 610 is limited and matched with the first seat limiting portion 510, and the arm limiting portion 410 is limited and matched with the fixed seat 100 or the vehicle body sheet metal.

[0036] That is to say, during the construction of the hinge structure 10, it is suitable to set the first link 200 and the second link 300 on the fixed seat 100, the first link 200 and the second link 300 are arranged at intervals, and the other ends of the first link 200 and the second link 300 are connected to the rotating arm 400, so that during the use of the hinge structure 10, the rotating arm 400 can be rotated at the connection between the first link 200 and the second link 300, so that the rotation process of the rotating arm 400 can be limited by the first link 200 and the second link 300. In addition, when the first link 200 and the second link 300 are connected to the fixed seat 100 and the rotating arm 400, they can be connected through the shaft pin 700, so that the first link 200 and the second link 300 can be rotated on the fixed seat 100 and the rotating arm 400 respectively, so as to realize the rotation adjustment of the hinge structure 10.

[0037] In this way, the hinge structure 10 has at least the following two usage states during use. In the first usage state, the first link 200 and the second link 300 are suitable for being rolled up to allow the rotating arm 400 to be constructed on the side closest to the fixed seat 100, that is, when the engine hood is closed, the rotating arm 400 is arranged close to the fixed seat 100, and in the second usage state, the first link 200 and the second link 300 are supported on the fixed seat 100, so that the rotating arm 400 is constructed on the side farthest from the fixed seat, that is, when the engine hood is opened, the rotating arm 400 is arranged away from the fixed seat 100.

[0038] In some specific embodiments, the fixed seat 100 is suitable for being connected to the vehicle body frame, and a first seat limiting portion 510 is provided on the fixed seat 100. The first seat limiting portion 510 is arranged relative to the first rod limiting portion 610 and is limitedly matched in the first use state, so that the rotating arm 400 can be supported and set on the fixed seat 100 under the restriction of the first seat limiting portion 510 and the first rod limiting portion 610, and the first rod limiting portion 610 is suitable for being constructed on one of the first connecting rod 200 and the second connecting rod 300 according to the setting requirements of the hinge structure 10. In order to facilitate understanding of the scheme, in this embodiment, it is suitable to construct the first rod limiting portion 610 on the first connecting rod 200, and the technical scheme of constructing the first rod limiting portion 610 on the second connecting rod 300 is similar to that on the first connecting rod 200. After seeing the technical scheme of this embodiment, those skilled in the art can know how to realize the position adjustment of the first rod limiting portion 610. For the technical effect after the position adjustment, those skilled in the art can derive it according to actual production needs, which will not be repeated here.

[0039] The rotating arm 400 is also provided with an arm stopper 410, which is used to cooperate with the fixing seat 100 or the body sheet metal in the first use state, that is, when the engine hood is closed, so that the setting of the rotating arm 400 on the upper side of the fixing seat 100 is more reliable, so that the subsequent design and assembly of the engine hood and the body sheet metal is more compact, so as to improve the use performance. In addition, since the first seat stopper 510, the first rod stopper 610 and the arm stopper 410 are provided on the hinge structure 10 for cooperation, when the engine hood is closed, the structural stability of the hinge structure 10 can buffer and absorb the vibration of the engine during operation, so as to avoid the shaking problem of the engine hood during the operation of the vehicle.

[0040] According to the hinge structure 10 of the embodiment of the utility model, a first seat limiting portion 510 is provided on the fixed seat 100, so that the first seat limiting portion 510 and the first rod limiting portion 610 are limited and matched. In addition, an arm limiting portion 410 is also provided on the rotating arm 400. The arm limiting portion 410 is configured to be limited and matched with the fixed seat 100 or the body sheet metal, so that when the rotating arm 400 is limited and matched on the fixed seat 100, the limiting effect is better, and the compactness of the hinge structure 10 can be improved. While realizing the miniaturized design of the hinge structure 10, the hinge structure 10 can also have higher performance to meet the use requirements, so as to avoid the vibration from being transmitted through the hinge structure 10, thereby reducing the collision damage to the engine hood.

[0041] In some embodiments, the fixing seat 100 is provided with a second seat limiting portion 520, and the second seat limiting portion 520 is located in front of the first seat limiting portion 510. When the engine hood is closed, the arm limiting portion 410 is limited and matched with the second seat limiting portion 520. It can be understood that the fixing seat 100 can be correspondingly provided with a second seat limiting portion 520, and the second seat limiting portion 520 is suitable for limiting and matching with the arm limiting portion 410, which can not only make the limiting effect between the fixing seat 100 and the rotating arm 400 more reliable, but also improve the structural stability of the hinge structure 10 when the engine hood is closed.

[0042] In some embodiments, the first seat stopper 510 is located at the rear end of the fixed seat 100, the first rod stopper 610 is located at the second connecting rod 300, and the second seat stopper 520 is located at the front end of the fixed seat 100. It is understandable that the position of the first seat stopper 510 on the fixed seat 100 can be adjusted according to design requirements to improve the applicability of the hinge structure 10 in the vehicle. In this embodiment, it is suitable to construct the first seat stopper 510 at the rear end of the fixed seat 100. In this way, the first rod stopper 610 can be arranged on the second connecting rod 300, so that the first rod stopper 610 can conflict with the first seat stopper 510 when the engine hood is closed, so as to improve the structural stability of the hinge structure 10 during assembly. At the same time, the second seat limiting portion 520 can also be constructed at the front end of the fixed seat 100, so that the second seat limiting portion 520 and the first seat limiting portion 510 can limit the hinge structure 10 from both ends of the hinge structure 10, so that the structure of the hinge structure 10 is more stable and reliable.

[0043] In some embodiments, the first seat limiting portion 510 is located between one end of the first connecting rod 200 and one end of the second connecting rod 300, the first rod limiting portion 610 is located at the first connecting rod 200, and the second seat limiting portion 520 is located at the front end of the fixed seat 100. In other words, the first seat limiting portion 510 can also be arranged between the first connecting rod 200 and the second connecting rod 300, so that the first seat limiting portion 510 can be limited and matched with the first rod limiting portion 610 arranged on the first connecting rod 200, so as to improve the stability of the hinge structure 10. At the same time, the second seat limiting portion 520 can be correspondingly arranged at the front end of the fixed seat 100, so that it can be limited and matched with the fixed seat 100 to stabilize the hinge structure 10.

[0044] In some embodiments, the limiting direction of the first seat limiting portion 510 and the first rod limiting portion 610 has an angle greater than 0 with the up-down direction; and / or the limiting direction of the arm limiting portion 410 and the second seat limiting portion 520 is the up-down direction. It is understandable that when the first seat limiting portion 510 and the first rod limiting portion 610 are in limiting cooperation, they can be adjusted according to the structural setting of the hinge structure 10, so that the position of the limiting cooperation of the first seat limiting portion 510 and the first rod limiting portion 610 has an angle with the up-down direction, so that the structural setting stability of the hinge structure 10 is improved, so that the hinge structure 10 has a higher performance to absorb and buffer vibration, so as to avoid the engine hood from colliding with other structures in the vehicle.

[0045] In some embodiments, one of the first seat limiting portion 510 and the first rod limiting portion 610 is constructed with a first adjusting member 530 and a first limiting plate 540 and the other is constructed with a second limiting plate 550, the first adjusting member 530 is arranged on the first limiting plate 540, and the first limiting plate 540 is limited and cooperated with the second limiting plate 550 through the first adjusting member 530; and / or one of the second seat limiting portion 520 and the arm limiting portion 410 is constructed with a second adjusting member 560 and a third limiting plate 570 and the other is constructed with a fourth limiting plate 580 with an adjusting member, the second adjusting member 560 is arranged on the third limiting plate 570, and the fourth limiting plate 580 is limited and cooperated with the third limiting plate 570 through the second adjusting member 560.

[0046] It is understandable that in some specific embodiments, the first seat limiting portion 510 may be provided with a first adjusting member 530 and a first limiting plate 540, and the first rod limiting portion 610 may be provided with a second limiting plate 550, so that when the first seat limiting portion 510 and the first rod limiting portion 610 are limited and matched, the position of the first adjusting member 530 on the first limiting plate 540 may be adjusted first, so that the first adjusting member 530 has a better limiting effect when it is matched with the second limiting plate 550, so that the structural stability of the hinge structure 10 is improved to absorb and buffer vibration. The setting of the first adjusting member 530 on the first limiting plate 540 may be adjusted according to the use requirements of the hinge structure 10, so that the stability of the first seat limiting portion 510 and the first rod limiting portion 610 when they are limited and matched is further improved.

[0047] Similarly, in some other specific embodiments, a second adjusting member 560 and a third limiting plate 570 can be constructed on the second seat limiting portion 520, and a fourth limiting plate 580 can be provided on the arm limiting portion 410, so that when the second seat limiting portion 520 and the arm limiting portion 410 are limited and matched, the setting position of the second adjusting member 560 on the third limiting plate 570 can be adjusted, so that the limiting effect of the second adjusting member 560 and the fourth limiting plate 580 when they are limited and matched is improved, so that the hinge structure 10 has higher structural stability to absorb and buffer the vibration of the engine, so as to avoid collision of the engine hood and the like.

[0048] In some embodiments, the first adjusting member 530 is a first adjusting screw, the rod of the first adjusting screw is threadedly connected to the first limiting plate 540, and the nut of the first adjusting screw is limitedly matched with the second limiting plate 550; the second adjusting member 560 is a second adjusting screw, the rod of the second adjusting screw is threadedly connected to the fourth limiting plate 580, and the nut of the second adjusting screw is limitedly matched with the second limiting plate 550.

[0049] It is understandable that the first adjusting member 530 can be set as a first adjusting screw, and the first adjusting screw is provided with an external thread, so that when the first adjusting screw is adjusted on the first limiting plate 540, it can be adjusted more accurately and reliably through the thread, thereby improving the limiting effect of the first seat limiting portion 510 and the first rod limiting portion 610. At the same time, the first adjusting member 530 is set as the first adjusting screw, so that when the first adjusting member 530 is set to limit, the nut of the first adjusting screw can also be limited with the second limiting plate 550 to achieve the limiting setting of the hinge structure 10.

[0050] Similarly, the second adjusting member 560 can also be set as a second adjusting screw. Since the second adjusting screw is provided with an external thread, when the second adjusting screw is adjusted on the third limiting plate 570, it can be adjusted more accurately and reliably through the thread, thereby improving the limiting effect of the second seat limiting portion 520 and the arm limiting portion 410. At the same time, the second adjusting member 560 is set as the second adjusting screw, so that when the second adjusting member 560 is set to limit, the nut of the second adjusting screw can also be limited and matched with the fourth limiting plate 580 to achieve the limiting setting of the hinge structure 10.

[0051] In some embodiments, the second connecting rod 300 is provided with a second rod limiting portion 620 . When the second connecting rod 300 rotates to the extreme position, the second rod limiting portion 620 cooperates with the rotating arm 400 in a limiting manner.

[0052] That is to say, a second rod limiting portion 620 may also be provided on the second connecting rod 300, and the second rod limiting portion 620 is provided at the end of the second connecting rod 300. When the second connecting rod 300 is rotated to the extreme position, the second rod limiting portion 620 can be limited and matched with the rotating arm 400 to avoid excessive rotation of the hinge structure 10 during use, so as to make the use of the hinge structure 10 more reliable, thereby better supporting the engine hood for use.

[0053] In some embodiments, the rotating arm 400 is provided with a support rod mounting portion 420, and the support rod mounting portion 420 is used to mount the support rod of the engine hood. It is understandable that the support rod mounting portion 420 is provided on the rotating arm 400, and the support rod mounting portion 420 is suitable for connecting with the support rod of the engine hood, so that the hinge structure 10 can drive the engine hood to move during use to realize the opening or closing of the engine hood.

[0054] The vehicle according to the embodiment of the utility model includes: the hinge structure 10 as described above. In this way, since the hinge structure 10 as described above is provided in the vehicle, by providing the first seat limiting portion 510 on the fixed seat 100, the first seat limiting portion 510 is allowed to cooperate with the first rod limiting portion 610 for limiting. Moreover, the rotating arm 400 is also provided with an arm limiting portion 410, and the arm limiting portion 410 is configured to cooperate with the fixed seat 100 or the body sheet metal for limiting. When the rotating arm 400 cooperates with the fixed seat 100 for limiting, the limiting effect is better, and the compactness of the hinge structure 10 can be improved. While realizing the miniaturized design of the hinge structure 10, the hinge structure 10 can also have higher performance to meet the use requirements, so as to avoid the vibration from being transmitted through the hinge structure 10, thereby reducing the collision damage to the engine hood.
