The first connecting member 1 and the second connecting member 2 are respectively connected to a cover plate and a vehicle body (not shown), but it is not limited to which one is connected, that is, the first connecting member 1 can be connected to the cover plate or connected. The second connecting member 2 can be connected to the vehicle body or can be connected to the cover plate. In this embodiment, the first connecting member 1 is connected to the cover plate and the second connecting member 2 is connected to the vehicle body as an example. Therefore, the second connecting member 2 is a fixing member (because it is connected to the vehicle body). The first connecting member 1 is a movable member that can rotate relative to the second connecting member 2 (because it is connected to the cover plate).

The first connecting member 1 defines a first pivot hole 11 .

The second connecting member 2 is provided with an actuating structure A. The actuating structure A includes: a second pivot hole 22 formed in the second connecting member 2 and a crushing plate 23 disposed or formed on the second connecting member 2, preferably further comprising a second connecting member 2 An opening 21, and the opening 21 has a front space and a rear space, each of which is not marked with a symbol. Accordingly, the crush plate 23 is formed in the rear space to partially close the opening 21, and the second pivot hole 22 is formed as the front space remaining in the opening 21 partially closed by the crush plate 23. In addition, it should be noted that the crushing plate 23 (or the actuating structure A) can be disposed on the first connecting member 1 or the second connecting member 2, and in the embodiment, is disposed on the second connecting member. Item 2 is taken as an example for explanation.

Embodiment 1 of the crushing plate 23: the crushing plate 23 can be a frangible plate, for example, a plate made of a collapsible material or a plurality of holes (or grooves) having been opened. The easily collapsible plate makes the frangible plate more vulnerable to crushing than the second connecting member 2; in other words, the thickness of the crushing plate 23 can be the same, larger or smaller than the thickness of the second connecting member 2. The present invention is not limited thereto, as long as the crushing plate 23 is more susceptible to crushing than the second connecting member 2. As for the arrangement, the frangible sheets are placed or formed in the rear space of the opening 21.

Embodiment 2 of the crushing plate 23: the thickness of the crushing plate 23 is made smaller than the thickness of the second connecting member 2 in various feasible manners, for example, in the space of the rear portion corresponding to the opening 21 of the second connecting member 2 Thin, it is possible to form the crushed sheet 23 having a smaller thickness than the second connecting member 2. As a result, the structural strength of the crushed sheet 23 is smaller than that of the second connecting member 2 and is easily crushed by force.

The present invention does not limit the embodiment of the collapsed plate piece 23. In the present embodiment, the above-described second embodiment will be described as an example.

Preferably, the crushing plate 23 can also have a force side edge 231 (see FIGS. 1 and 2), and the force side edge 231 is connected to the second pivot hole 22 to make the force side edge. The 231 is located on the edge of the second pivot hole 22 or the force receiving side edge 231 is correspondingly inserted into the edge of the second pivot hole 22 .

The rivet itself is pivotally connected to the first pivoting hole 11 and the second by riveting the rivet between the first connecting member 1 and the second connecting member 2 correspondingly to the first pivoting hole 11 and the second pivoting hole 22 The hole 22 is pivoted and the head 31 and the tail 32 are respectively blocked from the opposite outer sides of the first connector 1 and the second connector 2.

Preferably, the pivoting member 3 has an outer peripheral edge 33 corresponding to the second pivot hole 22 (see FIGS. 1 and 6A), and the shape of the force receiving side edge 231 may also correspond to the shape of the outer peripheral edge 33. In other words, the shape of the force side edge 231 is a concave arc corresponding to the outer circumference 33, so as to partially surround the second pivot hole 22 with a part of the inner edge of the opening 21, so that the second pivot hole 22 is There is an effect of pivoting the pivoting member 3 before the crushing plate 23 is not collapsed.

The blocking piece 4 is sleeved on the pivoting member 3, and the blocking piece 4 is sandwiched between the tail portion 32 and the outer side surface of the second connecting member 2 to ensure that the tail portion 32 of the pivoting member 3 does not occur when an impact occurs. It will come out from the opening 21, that is, when the impact occurs, it can be ensured that the first connecting member 1 and the second connecting member 2 are not detached. Preferably, the outer diameter of the blocking piece 4 is larger than the inner diameter of the second pivoting hole 22, and may be larger than the inner diameter of the opening 21, and may also be larger than the contour of the actuating structure A.

Thereby, when the vehicle collides with the pedestrian or the two-wheeled vehicle to cause the pedestrian or the knight to fall and hit the vehicle cover (not shown), the cover will first withstand the impact external force, which is then connected via the cover A connecting member 1 is transmitted to the pivoting member 3 to drive the pivoting member 3 to move toward the force receiving side edge 231 (refer to FIGS. 6 and 6A), and finally the pivoting member 3 forces the crushing plate 23 to collapse. (Not shown in the figure, the so-called collapse includes: being crushed and split, or being deformed by being squeezed), so that the pivoting member 3 generates a buffering force or absorption when the crushing plate 23 is forced to collapse. The impact force, thus reducing the reaction force when pedestrians or knights hit the vehicle cover, to protect pedestrians and protect the two-wheeled rider.

Moreover, the vehicle cover hinge of the present invention also has a simple structure, low cost, and a reliable crush protection effect.

In addition, the second pivot hole 22 and the crush plate 23 are respectively located in the front space and the rear space of the opening 21, so that the opening 21 has an effect of guiding from the front space to the rear space, in particular, the opening 21 is a In the case of the elongated hole, the pivoting member 3 is guided to have a better guiding effect, that is, the pivoting member 3 can be accurately moved toward the crushing plate 23 along the longitudinal direction of the elongated hole. Moreover, the length direction of the elongated hole is parallel to the direction of impact of the pedestrian or the two-wheeled rider, so that the present invention can have the effect of collapsing in the impact direction via the guide, thereby producing a better cushioning force or absorbing the impact force. .

In summary, the present invention can achieve the intended use purpose, and can solve the lack of the prior art, thereby achieving the effect described, and applying according to the patent law.
