Detailed Description

The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.

The embodiment of the invention relates to a variable front spoiler, as shown in fig. 1-3, a motor transmission structure 3 and a guide structure 4 are designed in the technical scheme, wherein a motor in the motor transmission structure 3 can drive a transfer block 5 to move up and down through a screw rod structure, the transfer block 5 can drive the front spoiler 1 to move up and down, a motor signal drives the front spoiler 1 to move up and down and adjusts the direction of air flow at the bottom of an automobile through the movement of the spoiler 1, the stress condition at the head of the automobile is improved, the driving safety is enhanced, the energy loss is reduced, and the transmission precision can be greatly improved through the motor and the screw rod structure.

As shown in fig. 4 and 5, the guide structure 4 can prevent the front spoiler 1 from shaking after being impacted by the airflow during high-speed movement of the vehicle, and particularly, can keep the front spoiler 1 stable during the high-speed movement.

As shown in fig. 4-7, the guide post 7 in the guide structure 4 can move up and down, and the lower end of the guide post is connected to the guide notch, so that when the current spoiler 1 vibrates, the guide post 7 can avoid shaking, and when the front spoiler 1 moves up and down, the guide post 7 also moves up and down, thereby greatly improving the working stability of the front spoiler 1.

In order to avoid the looseness of the guide post 7 during operation, a locknut 9 is selected as a lower end fixing piece of the guide post 7.

As shown in fig. 8, in order to ensure the sealing performance of the guide structure 4, the first protection cover 10 and the second protection cover 11 are arranged on the fixed plate 2 to form a seal with the guide structure 4, so as to ensure the normal operation of the guide post 7 in a severe environment.

The second bushing is an oilless bushing to ensure the guide post 7 to move normally and sequentially.

The embodiments described herein are merely illustrative of the spirit of the invention and various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope and spirit of the invention as defined by the claims.
