Referring to fig. 1, fig. 1 is a schematic diagram illustrating a counter information interaction device according to an embodiment of the present invention. The counter information interaction device provided by one embodiment of the utility model comprises a main shell 100, a supporting component 200 and a mounting component 300. The main case 100 is configured with a first mounting groove 110; the supporting member 200 is installed in the first installation groove 110, and the supporting member 200 can move closer to or away from the bottom wall of the first installation groove 110; the installation component 300 is used for accommodating and installing the human-computer interaction module 800, and the installation component 300 is accommodated in the first installation groove 110 and detachably connected to the groove wall of the first installation groove 110; the supporting member 200 can drive the mounting member 300 to move away from the bottom wall of the first mounting groove 110.

When different human-computer interaction modules 800 need to be replaced according to different application scenes, the mounting assembly 300 provided with the old human-computer interaction module 800 is detached from the groove wall of the first mounting groove 110 of the main shell 100, the mounting assembly 300 moves away from the bottom wall of the first mounting groove 110 under the action of the supporting assembly 200, so that the mounting assembly 300 is completely detached from the first mounting groove 110, and then the mounting assembly 300 provided with the new human-computer interaction module 800 is reinstalled in the first mounting groove 110. Compared with the prior art that the mounting assembly needs to be manually separated from the first mounting groove, the cabinet information interaction device provided by the embodiment utilizes the supporting assembly 200 to enable the mounting assembly 300 to automatically separate from the first mounting groove 110, so that the operation is simple and rapid, the dismounting time is shortened, and the labor cost is reduced.

The following describes the structure of the counter information interaction device in detail. Referring to fig. 2-5, fig. 2 is a schematic diagram illustrating the counter information interaction device shown in fig. 1 without the installation assembly 300 and the human-computer interaction module 800; FIG. 3 is a schematic diagram of the support assembly 200 of the counter information interaction device of FIG. 1; FIG. 4 is a schematic diagram of the mounting assembly 300 and the human-computer interaction module 800 in the counter information interaction device shown in FIG. 1; fig. 5 shows a schematic view of the installation of the positioning column 311 and the base 400 in the counter information interaction device shown in fig. 1.

Referring to fig. 3, a supporting assembly 200 of a counter information interaction device according to an embodiment of the present invention includes a first elastic member 210 and a supporting plate 220; one end of the first elastic member 210 is connected to the bottom wall of the first mounting groove 110, the other end of the first elastic member 210 is connected to the supporting plate 220, and the mounting assembly 300 abuts against one side of the supporting plate 220 away from the first elastic member 210; when the mounting member 300 is separated from the groove wall of the first mounting groove 110, the first elastic member 210 can push the supporting plate 220 to move away from the bottom wall of the first mounting groove 110. It should be noted that, when the installation assembly 300 is installed in the first installation groove 110, the first elastic member 210 is in a compressed state. Therefore, when the human-computer interaction module 800 needs to be replaced, the mounting assembly 300 mounted with the human-computer interaction module 800 is detached from the groove wall of the first mounting groove 110, the first elastic member 210 in the compressed state extends to push the supporting plate 220 to move away from the bottom wall of the first mounting groove 110, the supporting plate 220 pushes the mounting assembly 300 to move away from the bottom wall of the first mounting groove 110, and the mounting assembly 300 mounted with the old human-computer interaction module 800 is detached from the first mounting groove 110. When the installation assembly 300 with the new human-machine interaction module 800 installed is installed on the wall of the first installation groove 110, the first elastic member 210 is compressed again under the gravity of the installation assembly 300 and stores elastic potential energy. In one specific embodiment, the first elastic element 210 is a spring, but in other embodiments, the first elastic element 210 may also be an elastic pad, and the like, which is not limited thereto.

Referring to fig. 3, in the cabinet information interaction device according to an embodiment of the present invention, a second mounting groove 120 recessed along a depth direction of the first mounting groove 110 is disposed on a bottom wall of the first mounting groove 110, and the first elastic element 210 is accommodated in the second mounting groove 120, and one end of the first elastic element abuts against a bottom wall of the second mounting groove 120. The second installation groove 120 is arranged to accommodate the first elastic member 210, so that the problem that the first elastic member 210 is directly exposed in the first installation groove 110 and is easily damaged is avoided; meanwhile, the second mounting groove 120 can also limit the radial offset of the first elastic element 210, so that the first elastic element 210 can stretch along the axis direction (i.e., along the depth direction of the cavity of the second mounting groove 120) as much as possible, and the possibility of bending of the first elastic element 210 is reduced. In a specific embodiment, the width of the notch of the second mounting groove 120 is smaller than the radial length of the first elastic member 210, ensuring that the first elastic member 210 is not easily separated from the cavity of the second mounting groove 120.

With reference to fig. 3, the second mounting groove 120 of the counter information interaction device according to an embodiment of the present invention includes a containing cavity 121 and a communicating neck 122 that are connected to each other; the communicating neck 122 is used for communicating the accommodating cavity 121 and the first mounting groove 110, the neck diameter of the communicating neck 122 is smaller than that of the accommodating cavity 121, and the first elastic element 210 is accommodated in the accommodating cavity 121.

The diameter of the limiting head 231 is larger than that of the connecting cylinder 232, the diameter of the limiting head 231 is larger than the groove diameter of the communication neck 122, and the diameter of the connecting cylinder 232 is smaller than that of the communication neck 122. When the first elastic element 210 pushes the supporting column 230 to move along the length direction of the supporting column 230, the position-limiting head 231 slides in the accommodating cavity 121. With such an arrangement, when the first elastic member 210 releases elastic potential energy in a compressed state, the stopper 231 does not move into the communication neck 122, and thus the end of the first elastic member 210 close to the supporting plate 220 does not extend into the first mounting groove 110. The limitation of the movement stroke of the first elastic element 210 can be achieved by limiting the structural dimensions of the second mounting groove 120 and the supporting column 230, so that the first elastic element 210 cannot be separated from the cavity of the second mounting groove 120, and the safety and convenience are very high.
