When the height of the luggage rack body needs to be changed, the second electromagnetic magnetic block is electrified again, repulsive force is generated between the second electromagnetic magnetic block and the second limiting magnetic block, the second limiting magnetic block is separated from the second positioning hole of the second electromagnetic magnetic block, the motor drives the first connecting rod 505 to enable the first electromagnetic magnetic block 509 to horizontally move in the lifting sliding rail, the lifting sliding rail is changed in height, the luggage rack body is correspondingly changed in height, and accordingly the second connecting rod is driven to rotate, and the second electromagnetic magnetic block slides in the fixed sliding rail. Here, when the height of the luggage rack body is adjusted up and the height of the luggage rack body is adjusted down, the rotation direction of the second connecting rod and the sliding direction of the second limiting magnetic block are opposite.
In this embodiment, the plurality of first limiting portions and the plurality of second limiting portions may be disposed in one-to-one correspondence, or may be disposed in a staggered manner; the first electromagnetic block and the second electromagnetic block can be controlled respectively through the ECU, and the first electromagnetic block and the second electromagnetic block can be controlled simultaneously, so that the luggage rack body is switched between a folding storage state and an unfolding use state.
At least two of the connection assemblies of the vehicle roof rack are provided with a turntable 504. The vehicle luggage rack comprises four connecting components which are respectively distributed on the two luggage rack longitudinal rails 2 at intervals. The driving device comprises two driving parts, two of the four connecting components are provided with turntables 504, the four connecting components are respectively distributed on two sides of the luggage rack body 20 at intervals, and the two driving parts are respectively correspondingly arranged on two of the four connecting components, and the two connecting components are provided with the turntables 504. The two driving parts drive the two connecting components, so that the driving force of the vehicle luggage rack in switching between the folding storage state and the unfolding use state can be increased, in addition, the four connecting components are distributed on two sides of the luggage rack body 20 at intervals, and the supporting strength of the luggage rack body 20 in the unfolding use state can be increased.
In this embodiment, the driving structure 5 is a connection component with the turntable 504 and the driving part, the driven structure 7 is a connection component without the turntable (i.e. the driven structure 7 only includes a transmission mechanism), the two driving structures 5 are installed at two sides of the luggage rack body, the two driven structures 7 are also installed at two sides of the luggage rack body, and the driving structure 5 and the driven structures 7 are arranged at intervals with the vehicle roof interior handle; the two driving parts drive the two turntables 504 provided with the connecting components of the turntables 504 to rotate, so that the driving structure 5 drives the luggage rack body to change in height, and when the luggage rack body changes in height, the driven structure 7 can be driven to change in accordance with the driving structure 5, thereby realizing the switching of the luggage rack of the vehicle between the folded storage state and the unfolded use state.
Example 2
The invention also discloses a vehicle, which comprises the vehicle luggage rack in the embodiment 1. When the vehicle does not need to use the vehicle luggage rack, the vehicle luggage rack can be hidden in the top cover of the vehicle body, so that the resistance between the vehicle luggage rack and air is reduced, and meanwhile, the large noise generated by high-speed friction between the vehicle luggage rack and air flow is avoided, so that the driving fuel consumption is reduced, and the riding comfort is improved.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a further detailed description of the invention with reference to specific embodiments, and it is not intended to limit the practice of the invention to those descriptions. Various changes in form and detail may be made therein by those skilled in the art, including a few simple inferences or alternatives, without departing from the spirit and scope of the present invention.
