The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A bracket-free supporting plate is shown in figures 1 to 8 and comprises a bottom plate 1, wherein a containing groove 2 is formed in the middle of the bottom plate, and a supporting mechanism is arranged in the containing groove;

the supporting mechanism comprises a front supporting plate 3 and a rear supporting plate 4, one end of the rear supporting plate is hinged to the front supporting plate, the other end of the rear supporting plate is hinged to the bottom plate (hinged to the rear side wall of the accommodating groove through a pin shaft 5), and the upper surfaces of the front supporting plate and the rear supporting plate are not higher than the upper surface of the bottom plate when the supporting mechanism is in a flat state;

the bottom surface of the accommodating groove is provided with a plurality of positioning grooves 6 (each positioning groove is parallel to a hinge shaft which is used for hinging the front supporting plate and the rear supporting plate), and the front supporting plate supports against the positioning grooves to realize positioning when the supporting mechanism is in use.

The front support plate and the rear support plate are typically hinged by a hinge 7. Generally, the receiving groove is a closed structure having four side walls, i.e., a front side wall 8, a rear side wall 9, a left side wall 10, and a right side wall 11 as shown in fig. 4. Preceding backup pad and back backup pad can imbed the holding tank under the exhibition flat state in, can not occupy extra space, have guaranteed the integrality and the conventional service function of layer board.

The two ends of the hinge shaft respectively extend out of the supporting mechanism to form a cantilever structure 12, a transverse groove capable of containing the extending part of the hinge shaft is arranged on the bottom plate, the length of the extending part of the common hinge shaft is 1-2mm, when the front supporting plate needs to be erected, the extending part (cantilever) of the hinge shaft only needs to be pulled by hand to lift up and down, then the supporting mechanism is pulled out, the containing groove is exposed, further angle adjustment is facilitated, the transverse groove is communicated with the containing groove, the depth of the transverse groove is lower than the lowest edge of the hinge shaft, and in addition, the transverse groove is generally the size of an adult thumb.

When needing to pull out supporting mechanism and come to fix a position electronic product or books, only need to hold the hinge end with a finger, when mentioning the hinge, with the preceding backup pad of thumb (or other hand) press down, make preceding, back backup pad between form the contained angle, and according to the in-service use needs, after adjusting the contained angle size (confirming preceding backup pad inclination), with preceding backup pad free end card in the constant head tank of relevant position, can regard preceding backup pad as the support of electronic product or books, high durability and convenient use, the comfort level is good, can adapt to individualized demand.

In an alternative embodiment, as shown in fig. 5 and 6, in order to improve the stability between the front and rear supporting plates in use, a spring plate 13 (fig. 5 and 6 are only schematic views and mainly used for displaying the arrangement position of the spring plate, and generally, the spring plate is preferably embedded in the bottom surfaces of the front and rear supporting plates so as not to occupy additional space) can be arranged at the lower side of the supporting mechanism, and as a preferable mode, in order to improve the stability, as shown in fig. 7, the end of the front supporting plate is provided with a positioning tooth 14 protruding forwards; and the side wall of the front surface of the positioning groove is provided with an inward concave structure 15 matched with the positioning teeth.

The front supporting plate with the adjusted angle utilizes the positioning teeth on the lower side to be clamped at the concave structure, the elastic pieces provide opening acting force between the two supporting plates, the positioning teeth are guaranteed to be stably matched with the concave structure, when a mobile phone, a tablet personal computer or a book is placed on the front supporting plate, the supporting mechanism can form effective stable support, and the supporting mechanism is not easy to destabilize.

In order to improve the stability of the support mechanism, as shown in fig. 7, a support member 16 may be hinged to the lower side of the support plate, and the support member improves the stability of the front support plate by being supported in a reverse direction, and generally, the support member may be a plate-shaped structure, and the lower end thereof is also supported in the positioning groove. Generally, the support member is accommodated on the lower surface of the front support plate, and in the accommodated state, the support member does not protrude from the lower surface of the front support plate, so that the space occupation is reduced, and the structural arrangement is more convenient.

In an alternative embodiment, as shown in fig. 6, a positioning rod 17 is disposed between the front supporting plate and the rear supporting plate, positioning posts 18 are disposed at two ends of the positioning rod on a side facing the supporting mechanism, positioning holes 19 matched with the positioning posts are disposed on the side walls of the front supporting plate and the rear supporting plate, when the supporting mechanism is pulled up and needs to be positioned, the two positioning posts can be inserted into the corresponding positioning holes respectively, at this time, the positioning rod can effectively support the front supporting plate and the rear supporting plate, so as to avoid the change of the angle relationship between the front supporting plate and the rear supporting plate, and avoid the instability of the supporting mechanism.

In order to increase the friction force and prevent the electronic product or book leaning on the front support plate from slipping off, anti-slip pads 20 may be respectively disposed on two sides of the accommodating groove (on two sides of the front support plate).

The invention has novel structure, and the supporting mechanism can be accommodated in the accommodating groove under normal conditions without occupying additional space, so that the supporting plate can be used as a common seat supporting plate. When the electron product or books are discharged to needs to one side, then through pulling up supporting mechanism, make preceding backup pad slope to suitable angle, again with supporting mechanism fixed can, easy and simple to handle, service function is abundant. When the rack is used as an electronic product rack, the area without the supporting mechanism can be actually used as a space for holding water cups and food, so that the rack is wide in application and high in integration level.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
