Detailed Description

In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

As shown in fig. 1 to 4, the trunk auxiliary system includes a trunk floor and luggage tray 1, a lifting and rotating mechanism 2 and a driving motor 3, the lifting and rotating mechanism 2 is disposed below two sides of the luggage tray 1, the driving motor 3 drives the lifting and rotating mechanism 2 to lift the luggage tray 1 and extend out of the vehicle, and the edges of the periphery of the luggage tray 1 are higher than the middle part of the luggage tray to prevent articles from falling.

The lifting and rotating mechanism 2 includes a rear lift arm 201, a front lift arm 202, a fixed bracket 203, an upper mount 204, and a lower mount 205. The fixed support 203 is fixed on a metal plate of the vehicle body through bolts, so that the whole rigidity and bearing are ensured. The lower mount 205 and the fixed bracket 203 are linked by bolts, and the front and

rear lift arms

202 and 201 are linked by bolts with the lower mount 205 but may be rotated. The front and rear lifting

arms

202, 201 are bolted to the upper mounting base 204, but may be rotated, with the upper mounting base 204 bolted to the luggage tray 1.

Back lifting arm 201 is equipped with gear 2011 with lower mount pad 205 link outside, driving motor 3's axis of rotation is linked fixedly with back lifting arm 201 gear 2011, it can not rotate between relative, when driving motor 3 opens, driving motor 3 axis of rotation can drive back lifting arm 201 and rotate along gear 2011 center, two lifting arm upward rearward movement of lifting arm 202 and other one side before driving, thereby make the upward rearward movement of the luggage tray above, driving motor 3 has the position locking function, can automatic locking after the settlement position. The body of the driving motor 3 is fixed with the fixed bracket 203 through bolts and does not move relatively. The gear 2011 is matched with the rotating shaft of the driving motor 3 to prevent slipping.

A holder 4 is provided on the front side of the luggage tray 1 near the seat in the vehicle, and the holder 4 is mounted on the vehicle body at a central position below the luggage tray 1 for supporting the luggage tray 1 when the assist system is in a closed state.

As shown in fig. 1 to 3, when the auxiliary system is in a closed state, the luggage tray 1 is in an original position, the use of other functions on the vehicle is not affected, the luggage tray 1 is flat on the trunk floor, and the spare tire is arranged under the luggage tray 1 as in the conventional vehicle.

As shown in fig. 5 to 7, when the trunk auxiliary system is in an open state, the rear lifting arm 201 is driven by the driving motor 3 to make the luggage tray 1 do a fan-shaped motion keeping parallel, and after the trunk auxiliary system is opened, the luggage tray 1 can extend out of the vehicle by 100mm to 200mm and be lifted by 0mm to 100 mm.
