Referring to fig. 2 to 4, the present utility model provides a buffer mechanism of a nacelle cover 1, comprising: a lower buffer block 4 provided on the vehicle body 3; one of the two opposite surfaces of the lower buffer block 4 and the vehicle body 3 is convexly provided with a convex part 5, and the other surface is concavely provided with a concave part 6 corresponding to the convex part 5;

the lower buffer block 4 can rotate relative to the vehicle body 3, the buffer block rotates until the protruding part 5 enters the recessed part 6, and the height of the lower buffer block 4 is reduced; when the bumper rotates until the protruding portion 5 and the recessed portion 6 are offset and abut against the vehicle body 3, the height of the lower bumper 4 increases.

The effect of the elevation of the lower buffer block 4 is shown in fig. 4, in which the gap between the lower buffer block 4 and the vehicle body 3 is the elevation of the boss 5, and the elevation design is defined after calculation according to the dimension engineering.

The lower cushion block 4 in this embodiment is applied to the cabin cover 1 on the vehicle. When the automobile twists in the process of driving a curve, the cabin cover 1 can generate certain lateral displacement, and in order to better prevent the cabin cover 1 from interfering with peripheral components, the lower buffer block 4 can be arranged in the cabin to buffer, limit and buffer the cabin cover 1. In practical use, in order to enable the lower cushion block 4 to exert its maximum effect, the lower cushion block 4 is generally provided on the vehicle body 3 so as to be inclined at a certain angle with respect to the vertical direction. The arrangement is such that the lower buffer block 4 has a Y-and Z-component support for the nacelle cover 1. In the straight-road running process, the lower buffer block 4 provides Y-direction supporting force to support the cabin cover 1; the lower buffer block 4 provides a component force in the Z direction to support the cabin cover 1 during the curve driving process, so that the support of the cabin cover 1 is prevented from shifting.

The material of the lower cushion block 4 is a deformable cushion material. Preferably, the material of the buffer block 4 is rubber. In practical application, the lower buffer block 4 is mounted on the vehicle body 3, and is fastened by bolts under the design torque, and the lower buffer block 4 is low in height. Closing the cabin cover 1 to see whether the functional requirement is met, if not, loosening the bolts to loosen the lower buffer block 4 from the vehicle body, and then fastening the bolts under the design torque after the lower buffer block 4 rotates by a certain angle along the rotation center of gravity, wherein the height is higher when the adjusting is performed, and paying attention to the fact that the protruding part 5 of the bolts is not aligned with the recessed part 6.

Referring to fig. 2 and 3, in some possible embodiments, the protruding portion 5 is provided on the lower bumper 4, and the recessed portion 6 is provided on the vehicle body 3. The shape of the boss 5 may be columnar, truncated cone, irregular cube, or the like. The shape of the concave portion 6 may correspond to the shape of the convex portion 5, or the area of the concave portion 6 may be made larger than the area of the convex portion 5, as long as the convex portion 5 is ensured to be able to enter the concave portion 6. The specific positions and shapes of the protrusions 5 and the depressions 6 may be set by those skilled in the art according to actual application, and are not particularly limited herein.

Preferably, the protruding portion 5 is a lower positioning column protruding on the lower buffer block 4, and the recessed portion 6 is a lower positioning hole concavely arranged on the vehicle body 3. In this embodiment, the lower positioning column is a cylinder, and the lower positioning hole is a circular hole. The specific number of the lower cylinders is three and is disposed on the lower surface of the lower cushion block 4 at uniform intervals, and correspondingly, the number of the lower positioning columns is also three and is disposed on the upper surface of the vehicle body 3 at uniform intervals. So set up, three down reference column or three down locating hole can form equilateral triangle, and stability is higher, in addition, through setting up lower reference column and lower locating hole of less quantity and make down buffer block 4 can fix on automobile body 3, compare in the structure of other quantity, three down reference column or three down locating hole quantity is few, and the atress is balanced more, and stability is higher.

Referring to fig. 1, 5 and 6, in an alternative embodiment, the buffer mechanism further includes an upper buffer block 2 disposed on the cabin cover 1, and when the cabin cover 1 is covered on the vehicle body 3, the upper buffer block 2 abuts against the lower buffer block 4. Here, the upper cushion block 2 is fixed to a position corresponding to the lower cushion block 4 on the lower surface of the nacelle cover 1. In this embodiment, the upper buffer block 2 and the lower buffer block 4 are in contact with each other, so that the direct effect of the metal on the nacelle cover 1 and the lower buffer block 4 is avoided, and the problem that the nacelle cover is damaged by the lower buffer block 4 is avoided. The upper buffer block 2 and the lower buffer block 4 are both made of deformable buffer materials. In practical use, in order to enable the upper cushion block 2 and the lower cushion block 4 to exert their maximum effects, the lower cushion block 4 is generally provided on the vehicle body 3 so as to be inclined at a certain angle with respect to the vertical direction, and accordingly, the upper cushion block 2 is inclined at the same angle as the lower cushion block 4. When the cabin cover 1 is deviated in the curve driving process, the upper buffer block 2 extrudes the lower buffer block 4, the cabin cover 1 is buffered through deformation of the upper buffer block and the lower buffer block, and meanwhile, the lower buffer block 4 provides a component force in the Z direction to support the cabin cover 1, so that the supporting of the cabin cover 1 is prevented from deviating.

In an alternative embodiment, the upper bumper 2 has a hardness less than the lower bumper 4. In practical applications, the buffer mechanism needs to be made of soft materials and hard materials. If the same soft material is used for the upper buffer block 2 and the lower buffer block 4, the supporting force is insufficient; if the same hard material is used for the upper buffer block 2 and the lower buffer block 4, the buffering effect is poor, and the expected buffering effect cannot be achieved. Preferably, the material of the upper buffer block 2 is rubber material, plays main cushioning effect, and the lower buffer structure is plastic material, plays spacing and supporting role.

Referring to fig. 5, in an alternative embodiment, an anti-rotation structure 7 is disposed between the upper buffer block 2 and the nacelle cover 1, and the anti-rotation structure 7 is used to limit the relative rotation between the upper buffer block 2 and the nacelle cover 1. If the upper buffer block 2 is made of rubber, when the upper buffer block 2 is mounted on the cabin cover 1, the upper buffer block 2 is usually fixed by bolts, and relative rotation can occur between the upper buffer block and the cabin cover, so that the structure of the cabin cover 1 is worn, and therefore, an anti-rotation structure 7 needs to be arranged to limit rotation. Since the lower buffer block 4 is made of plastic, the structure of the vehicle body 3 is not worn even if the lower buffer block 4 is relatively rotated when being mounted on the vehicle body 3, and therefore, the anti-rotation structure 7 is not required.

Specifically, the anti-rotation structure 7 includes an upper positioning post 71 and an upper positioning hole 72 corresponding to the upper positioning post 71, the upper positioning post 71 is convexly arranged on one of two mutually adjacent surfaces of the upper buffer block 2 and the cabin cover 1, and the upper positioning hole 72 is concavely arranged on the other one of the two mutually adjacent surfaces of the upper buffer block 2 and the cabin cover 1; the upper positioning posts 71 enter the upper positioning holes 72 to limit the relative rotation of the upper buffer block 2 relative to the cabin cover 1. The number of the upper positioning posts 71 and the upper positioning holes 72 in the present embodiment is set to be one, and the upper positioning posts 71 can achieve the anti-rotation purpose only by inserting the upper positioning holes 72.

Referring to fig. 1, alternatively, a flange 41 is formed on a surface of the lower buffer block 4 opposite to the upper buffer block 2, and an outer contour of the flange 41 corresponds to an outer contour of the upper buffer block 2. The lower buffer block 4 is made of plastic, has harder texture, and can have smaller contact surface with the vehicle body 3, and the used material is smaller; the upper buffer block 2 is of a rubber structure, has a soft texture and has a relatively large contact surface with the cabin cover 1. In order to ensure the cushioning effect and the supporting effect, the outer contour of the flange 41 at the top of the lower cushion block 4 corresponds to the corresponding contact surface of the outer contour of the upper cushion block 2. So set up, when realizing subtracting the material purpose, ensured the buffering effect and the supporting role between the upper buffer block 2 on the lower buffer block 4.

Referring to fig. 2 and 5, in an alternative embodiment, the upper bumper 2 is fixed to the cabin cover 1 by the first blind rivet nut 11 and the first bolt 12, and the lower bumper 4 is fixed to the vehicle body 3 by the second blind rivet nut 31 and the second bolt 32. The cabin cover 1 and the vehicle body 3 are metal sheets, if the upper buffer member or the lower buffer member is fixed by a nut welding mode, the cabin cover 1 or the vehicle body 3 is easy to be welded through, and if internal threads are tapped on the cabin cover 1 and the vehicle body 3, teeth are easy to slide during installation. The buffer block is fixed through the rivet nut and the bolt, so that internal threads are not required to be tapped, the nut is not required to be welded, and the riveting is firm, high in efficiency and convenient to use.

Referring to fig. 3 and 6, in an alternative embodiment, a central portion of the upper cushion block 2 is recessed toward the cabin cover 1 to form a first receiving portion 20 for receiving the first bolt 12, and a central portion of the lower cushion block 4 is recessed toward the vehicle body 3 to form a second receiving portion 40 for receiving the second bolt 32. So set up, can hide the bolt through the holding part, ensure that the cabin cover 1 lid closes when on the car, go up buffer block 2 lower surface and the upper surface of buffer block 4 down and laminate completely, buffering effect and supporting effect are better, reduce simultaneously and make the material that buffer block 2 and buffer block 4 used down, reach the purpose of subtracting the material.

The present embodiment also provides a vehicle including the damper mechanism of the cabin cover 1 of any one of the above.

The vehicle using the buffering mechanism has the advantages of being simple in structure and low in price, achieving functions of the adjustable lateral limiting buffering mechanism to a certain extent, and improving convenience in adjustment.

The foregoing description of the preferred embodiment of the present utility model is provided for the purpose of illustration only, and is not intended to limit the utility model to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
