[0039] Furthermore, in the present invention, the push reel 3 is connected with a winding spring; the setting of the winding spring can provide a rotational driving force for the push reel 3, so as to facilitate the subsequent winding of the protective net 4.

[0040] Furthermore, in the utility model, the driving mechanism includes two driving components, and the two driving components are distributed on both sides of the end of the protective net 4; based on such a configuration, the two sides of the protective net 4 can be driven synchronously, and the protective net 4 can be opened quickly.

[0051] specific:

[0052] The utility model discloses a protection device for vehicle rollover; the lower storage box 2 disclosed in the utility model is used to store the rolled-up protection net 4, the push reel 3 is the lower end connecting piece of the protection net 4, which is convenient for binding the lower end of the protection net 4, and at the same time, the push reel 3 is connected with a spring sheet, which has the functions of extension and contraction; and the protection net 4 is used to ensure the occurrence of the anti-throwing situation and play a blocking role, the driving part 6 is mainly a driving motor, and its main function is to drive the working wheel 5 to have the ability to move up and down quickly in the door frame, and at the same time, the protection net 4 can be dragged to realize the rapid blocking of the rear door window, so as to protect the passengers in the car from being thrown out.

[0053] In addition, the running track 7 disclosed in the present utility model mainly includes an upper limit track 71 arranged on the left side and a lower limit track 72 arranged on the right side.

[0054] A plurality of limiting parts 8 are provided on the limiting upper rail 71 , and each limiting part 8 includes a limiting card 81 . The function of the limiting card 81 is to prevent the motor from sliding off.

[0055] The lower limit track 72 is a simple track, which ensures that the protection net 4 driven by the motor can run up and down smoothly to ensure that the driving motor and the motor driving wheel run on the specified track.

[0056] The limit card 81 is connected to the vehicle door frame 1 through the rotating shaft 82. When it is used later, the natural gravity is used to achieve the natural balance of the limit card 81. When the driving motor drives the driving working wheel 5 to move upward quickly, the limit card 81 is driven by the upward force of the driving wheel to separate from the limit upper track 71; that is, it naturally retreats upward to the inside of the embedded sink groove 11, and after the driving wheel passes, the rotating shaft 82 drives the limit card 81 to naturally return to the protruding driving track under the action of gravity. At this time, if the driving wheel falls, it will not be able to fall to achieve the purpose of getting stuck because it overwhelms the plane position of the limit card 81, and it cannot continue to fall back, thereby achieving the limiting effect.

[0057] The function of the rotating shaft 82 is to drive the limit card 81 to achieve the purpose of turning upward at about 60-90 degrees and falling back.

[0058] The driving motor working wheel, under the action of the motor, works in the upper limit track 71 and the lower limit track 72 to quickly pull up the protection net 4.

[0059] The limit card 81 prevents the motor-driven working wheel 5 from sliding down and popping out halfway when a failure occurs, which can ensure that more than half of the window area is blocked.

[0060] The launch outlet 21 of the lower storage box 2 ensures that the protective net 4 has enough space for release. The position is located at the inner panel of the door, above the protective net 4; and the limiting lower track 72 has the same function as the limiting upper track 71 to form a symmetrical and effective protective net 4.

[0061] Working principle: when the driving motor of the protective net 4 receives the airbag pop-up signal, it quickly drives the corresponding driving working wheel 5, launches from the outlet 21 of the protective net 4, and drives the protective net 4 from the storage box of the protective net 4. With the help of the pushing reel 3 of the protective net 4, it runs upward along the upper limit track 71 and the lower limit track 72. When passing through the limit card 81, the driving working wheel 5 passes through each limit card 81 smoothly under the action of the rotating shaft 82. After the apex, the driving wheel will slide down under the action of gravity. At this time, the limit card 81 will prevent the sliding action from occurring.

[0062] At the same time, in actual use, the driving parts 6 on both sides of the protective net 4 work synchronously, so that the protective net 4, through the symmetrical action of the corresponding left and right running tracks 7, forms a protective net 4 for the rear passenger windows to prevent the second row passengers from being thrown out of the car when they are not wearing seat belts.

[0063] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
