The fifth distance measuring sensor 4 is fixed on the fifth connecting piece 28 through a buckle, and the fifth connecting piece 28 is fixed on the screen frame 16 through a screw. The fifth distance measuring sensor 4 is a laser sensor, and the fifth connecting element 28 is a sensor support. The laser sensor triggers a judging mechanism by detecting the distance between the front passenger and the equipment, for example, when the passenger is 3m away from the equipment, a special light effect is triggered, a horn sound effect is linked, the attention of the passenger is attracted, and the content exposure is increased.

The mounting structure of the display board assembly is as follows: the top of the first display board 1 is provided with two protrusions 25, two grooves 22 are designed corresponding to the inner surface of the mounting frame 5, and the first display board 1 is inserted and positioned through the grooves 22; the advertising board is fixed on the locking frame 24 through two hand-screwed screws, and the locking frame 24 is fixed on the screen frame 16 through the screws. More specifically, the first display board 1 is provided with a connecting column 23 matched with a screw, and the locking frame 24 is provided with a connecting hole matched with the connecting column 23. For example, during installation, the connecting column 23 can be inserted into the connecting hole, and then a screw is screwed on the connecting column 23, so that the connecting column 23 cannot be separated from the connecting hole, and finally the installation is completed. When the content of the first display board 1 needs to be replaced and updated, the locking screw can be detached and replaced quickly, the time of a merchant is saved, and meanwhile, the operation is convenient; compared with a sticking mode, the problem of adhesive residue is avoided. The mounting structure of the corresponding second display board 6 is symmetrical to the first display board 1.

The features of the above embodiments may be arbitrarily combined, and for the sake of brevity, all possible combinations of the features in the above embodiments are not described, but should be construed as being within the scope of the present specification as long as there is no contradiction between the combinations of the features.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be taken as limiting the present invention, and that suitable modifications and variations of the above embodiments are within the scope of the invention as claimed.
