A first embodiment of the present utility model provides a hinge device for a hood, as shown in fig. 1 to 5, which is provided between an engine compartment and a hood of a vehicle, for opening the hood and maintaining the hood in an open state with respect to the engine compartment when maintenance of an engine or the like in the engine compartment is required. Specifically, the hinge device comprises a hinge base 2 and a rotating arm 1, wherein the end part of the rotating arm 1 is rotatably connected with the hinge base 2, the hinge base 2 is fixedly arranged on a sheet metal structure in the engine compartment, the rotating arm 1 is connected with the engine cover, and thus the rotating arm 1 can rotate around the hinge base 2, so that the engine cover can be opened relative to the engine compartment.

Further, in order to limit the opening degree of the hood and to keep the hood in the open state, a first stopper 111 is provided at a position of the rotating arm 1 near an end thereof, and a second stopper 21 is provided on the hinge base 2, wherein the second stopper 21 is located on a rotating path of the first stopper 111 when the rotating arm 1 rotates, wherein a positional relationship between the first stopper 111 and the second stopper 21 is related to the opening degree of the hood. In this way, the first stopper 111 abuts against the second stopper 21 when the hood is in the open state, so that the hood can be kept in the open state. The first limiting portion 111 and the second limiting portion 21 abut against each other to limit the rotating arm 1, so that the rotating arm 1 and the engine cover cannot be further opened, and interference and collision between the rotating arm 1 and other structural members of the engine cover and other structural members of the vehicle are avoided. In this embodiment, the limiting structure of the hinge device is disposed in the middle of the rotating arm 1 to limit, so that the limiting structure no longer occupies the arrangement space of the top and the rear of the hinge device.

Specifically, in order to cope with different demands, the hood may be brought into two states by the hinge device, wherein the first state is an open state, that is, when a user opens the hood to an open state, the first limiting portion 111 on the rotating arm 1 and the second limiting portion 21 on the hinge base 2 abut against each other at this time, so that the hood is maintained at a predetermined open position, and the user can easily view and repair the components in the engine compartment; the second state is a closed state, that is, when the user completely closes the hood, and the first stopper 111 and the second stopper 21 are separated from each other, and the hood is completely covered on the engine compartment. In this way, the conversion of the hood from the first state to the second state can be achieved by the rotation of the rotating arm 1 relative to the hinge base 2.

In this embodiment, the second limiting portion 21 is disposed on the rotation path of the first limiting portion 111 to achieve mutual abutment between the first limiting portion 111 and the second limiting portion 21, which not only can be used to achieve a limiting effect when the engine cover is in an open state, but also can simplify the structure of the hinge device, thereby improving the utilization efficiency of space.

Further, as shown in fig. 1, the rotating arm 1 includes an integrally formed hinge portion 11 and a supporting portion 12, where the hinge portion 11 is located at an end where the rotating arm 1 and the hinge base 2 are rotatably connected to each other, so that the hinge portion 11 and the hinge base 2 can be rotatably connected without affecting maintenance operation in the engine compartment. Specifically, in some embodiments, as shown in fig. 2 and 4, the hinge portion 11 may be rotatably connected with the hinge base 2 through the pin shaft 3, so that the connection between the hinge portion 11 and the hinge base 2 may be more stable through the pin shaft 3, the mutual rotation may be smoother, and the loss caused by the friction of the members during the relative rotation may be avoided, thereby prolonging the service life.

Further, the supporting portion 12 is fixedly connected to the engine cover, so as to support the engine cover when the engine cover is in an open state. In addition, according to the positional relationship between the hood and the engine compartment, the hinge portion 11 and the support portion 12 may have an angle therebetween, so that when the user opens or closes the hood, the hood can drive the support portion 12 to rotate the hinge portion 11 with respect to the hinge base 2.

Further, the hinge portion 11 and the supporting portion 12 are smoothly connected and integrally formed, wherein the integral forming process includes, but is not limited to: casting, forging, extrusion, welding, cutting, laser machining, rapid prototyping (e.g., 3D printing), and the like.

In some embodiments, as shown in fig. 1, 3 and 5, in order to connect with the engine cover, the support portion 12 is provided with a first flange 121, and the rotating arm 1 is connected with the engine cover through the first flange 121. Specifically, the shape of the first flange 121 matches with the shape of the bottom surface of the engine cover so that the first flange 121 and the engine cover can be attached to each other, ensuring the stability of the connection between the rotating arm 1 and the engine cover; in addition, the first flange 121 is provided with a connecting hole, and a fastening member such as a bolt may be engaged with the connecting hole to fixedly connect the engine cover with the first flange 121.

In some embodiments, as shown in fig. 5, a second flange 22 is disposed on a side of the hinge base 2 away from the rotating arm 1, the hinge base 2 is fixedly connected to the sheet metal structure of the engine compartment through the second flange 22, and the disposition position of the second flange 22 is determined according to the structure of the engine compartment, so that the hinge base 2 can be stably fixed on the engine compartment. In this embodiment, a reinforcing structure, such as a raised reinforcing rib, may be further provided on the second flange 22 of the hinge base 2. In addition, the second flange 22 is further provided with a mounting hole, and the hinge base 2 can be fixedly connected with the sheet metal structure through the cooperation of the fastener and the mounting hole.

In some embodiments, as shown in fig. 1, 3 and 5, considering that the hood is large, which may result in a longer length of the rotating arm 1, the rotating arm 1 further includes a dodging portion 13, for this purpose, the dodging portion 13 is located between the hinge portion 11 and the supporting portion 12 and can lengthen the overall length of the rotating arm 1, and is bent to a position away from the second limiting portion 21 to dodge the second limiting portion 21 when the rotating arm 1 rotates.

Specifically, in this embodiment, the hinge 11 is connected to the support 12 through the avoiding portion 13, and by providing the avoiding portion 13, interference collision between the rotating arm 1 and the second limiting portion 21 on the hinge base 2 during rotation can be avoided. For this reason, the avoidance portion 13 is bent in a direction away from the hinge base 2, so that the rotating arm 1 can freely rotate with respect to the hinge base 2, thereby ensuring smoothness and safety in the opening and closing process of the hood.

Further, the specific structures of the first limiting portion 111 and the second limiting portion 21 involved in the present embodiment may be set according to the needs. In a specific embodiment, as shown in fig. 2 to fig. 4, the first limiting portion 111 may be a boss on the hinge portion 11, an opening 23 is provided on the hinge base 2, the second limiting portion 21 is a tongue structure disposed at the opening 23, and the boss may be abutted with the tongue structure. In this embodiment, in the specific manufacturing process, the opening 23 is formed by cutting or the like at a position corresponding to the first limiting portion 111, and the plate structure at the opening 23 is folded toward the direction of the rotating arm 1 to obtain the second limiting portion 21.

In addition, the first limiting structure 111 may be bird's beak or hook, and the first limiting structure 111 having the above shape may be in contact with the tongue structure more stably without being easily separated from each other, so as to ensure the stability of the engine cover in the open state.

A second embodiment of the present utility model provides a hood assembly comprising a hood and a hinge apparatus as described in any one of the above.

According to the utility model, the engine cover can be opened by rotating the rotating arm relative to the hinge seat, and meanwhile, a better limiting effect is realized on the engine cover by mutually abutting the first limiting part and the second limiting part, and in addition, the limiting structure is arranged on the rotating arm without occupying the arrangement space at the top and the rear part of the hinge device, so that the convenience of opening the engine cover is improved.
