In the related art, in an opened state of an engine cover, a support bar is generally provided between the engine cover and a vehicle body by hand to maintain the opened state of the engine cover, and the operation steps are complicated. The gas spring can also be used to support the hood, but the gas spring is costly and in the hood closed state, the supporting force of the gas spring becomes large to affect peripheral parts, and the suitability is poor.

In the engine cover assembly 1, one end of the first supporting rod 13 is hinged with the bracket 11, one end of the second supporting rod 14 is hinged with the engine cover 12, and the second supporting rod 14 is slidably connected with the first supporting rod 13. During the process of rotating the engine cover 12 relative to the vehicle body, the second support bar 14 and the first support bar 13 can slide relatively to adjust the combined length of the first support bar 13 and the second support bar 14. During the process of the hood 12 from the closed state to the open state, the second support bar 14 slides in the extending direction of the first support bar 13 to extend to the extended state. The extended state is a state where the hood 12 is kept open, and the second support lever 14 is extended opposite to the first support lever 13 to support the hood 12. By arranging the first support rod 13 and the second support rod 14, the first support rod 13 and the second support rod 14 connect the engine cover 12 with the vehicle body so as to support the engine cover 12 when the engine cover 12 is in an open state, simplify the opening and closing operation of the engine cover 12, and facilitate the detection and maintenance of parts in the engine compartment.

In addition, under the closed state of the engine cover 12, the second supporting rod 14 is contracted relative to the first supporting rod 13, the combined length of the first supporting rod 13 and the second supporting rod 14 is small, the occupation of the first supporting rod 13 and the second supporting rod 14 to the space in the engine compartment can be reduced, and the adaptability is good.

The contracted state is a relative state in which the hood 12 is kept in a closed state, and the second support lever 14 and the first support lever 13 are relatively contracted. The limiting member 15 may be rotatably disposed on the first support rod 13 or may be rotatably disposed on the second support rod 14. The first support rod 13 and the second support rod 14 are respectively provided with a limiting hole 100, and the limiting holes 100 on the first support rod 13 and the limiting holes 100 on the second support rod 14 can be at least partially communicated when in an extending state, so that the limiting piece 15 can be matched with the limiting holes 100 to limit the second support rod 14 to shrink relative to the first support rod 13, the limiting step is simplified, and the convenience is improved.

For example, the limiting member 15 is rotatably disposed on the first supporting rod 13, and in the process that the second supporting rod 14 slides relative to the first supporting rod 13 to enable the second supporting rod 14 to extend relative to the first supporting rod 13, the limiting member 15 rotates and the limiting hole 100 on the first supporting rod 13 is at least partially communicated with the limiting hole 100 on the second supporting rod 14, and at least part of the limiting member 15 can pass through the limiting hole 100 and stop against the second supporting rod 14 to limit the second supporting rod 14 to shrink relative to the first supporting rod 13.
