In the present specification, the back shell with retractable foot pads has at least a pop-up foot pad state and a retractable foot pad state. Referring to; Figures 1-26 When the back shell with retractable foot pads is in the retractable foot pad state, if the press protrusion is subjected to an outward pushing force applied by the outside world, the pushing force is transmitted to the sawtooth protrusion, the sawtooth protrusion is in contact with at least one rotating protrusion, and the rotating protrusion slides outward in the gap; due to the contact between the tip of the sawtooth protrusion and the rotating slope, the rotating member has a tendency to rotate in the first direction, but the rotating tendency is limited by the gap; when the rotating protrusion slides out of the gap, the rotating member rotates in the first direction; at this time, if the force applied by the outside world to the press protrusion stops, the rotating member slides inward under the action of the spring force transmitted by the connecting rod; since the rotating member has rotated a small distance in the first direction, when the rotating member slides inward, the rotating protrusion is in contact with the first surface of one protrusion; the rotating member rotates in the first direction while sliding inward until at least one rotating protrusion is engaged with the first surface and the second surface of one protrusion, and the rotating member cannot continue to slide and rotate; at this time, the back shell with retractable foot pads is in the pop-up foot pad state; when the back shell with retractable foot pads is in the pop-up foot pad state, due to the inward pushing force of the spring transmitted to the rotating protrusion, at least one rotating protrusion is clamped between the first surface and the second surface of one protrusion; at this time, if the press protrusion is not subjected to the force of the outside world, the rotating protrusion can slide freely in the bottom hole; if the press protrusion is subjected to an outward pushing force applied by the outside world, the tip of the sawtooth protrusion is in contact with at least one rotating slope; there is a state (referred to as the first state) in which a part of the rotating protrusion is in contact with the first surface and the second surface of one protrusion, and another part of the rotating protrusion is in contact with the sawtooth protrusion; when the pushing force applied to the sleeve is transmitted to the rotating protrusion, the rotating protrusion has a tendency to slide outward, the first state is released - when the rotating protrusion begins to slide outward, it is out of contact with the aforementioned first surface, but the rotating tendency of the rotating member in the first direction caused by the force acting on the rotating slope makes the rotating protrusion still in contact with the second surface until the rotating protrusion slides out of contact with the second surface, the rotating tendency of the rotating member cannot be limited by the second surface, at this time the rotating protrusion rotates in the first direction; at this time, if the outside world stops applying force outward, the rotating protrusion slides inward under the action of the spring force, so that the rotating slope is in contact with the aforementioned third surface; at this time, the rotating member continues to rotate in the first direction until the rotating protrusion is limited by the gap between the two protrusions; at this time, if the outside world stops applying force outward, the rotating protrusion slides to the bottom of the aforementioned gap under the action of the spring force, at this time the back shell with retractable foot pads is in the retractable foot pad state.

Figure 24As shown, from Figure 23 Starting in the state shown, pressing the protrusion without external outward pushing force allows the protrusion to penetrate deeper into the notch. Due to the lateral restriction of the notch, the protrusion cannot rotate in the first direction; as shown... Figure 25 As shown, from Figure 24 As shown, at least one rotating protrusion is fully inserted into the notch, and the foot pad head retracts partially; under the action of the spring force, the connecting rod, rotating protrusion, and sleeve will continue to slide inward until... Figure 17 The image shows the retracted foot pad position. In practical applications, refer to... Figure 16 The outer side of the back shell with telescopic feet has a support plate groove, within which two back shell pivots are arranged. The other part of each pivot is fixed to the support plate, allowing the support plate to rotate relative to the support plate groove. The inner side of the back shell of the telescopic feet has a side opposite to the support plate groove, and a portion of the pivot is fixed to the inner side of the back shell. A magnetic attraction mechanism is provided on the support plate, and the back shell with telescopic feet has an internal magnetic attraction component. The magnetic attraction mechanism and the internal magnetic attraction component attract each other, allowing the support plate to be secured within the support plate groove. Figure 16 In the diagram, the side opposite the bracket plate groove is unrelated to the mounting cover 5 and does not interfere with it. In practical applications, the bracket plate, bracket plate groove, and back cover hinge are not essential components of a back cover with telescopic feet. (Refer to...) Figure 26 The back shell with retractable feet can be equipped with a foot pad head; Figure 26 The “one mounting hole” is used to fix the display device to other components via a hinge. The “one mounting hole” is not a necessary component for the back shell with telescopic feet, nor is it a necessary component for the display device. In practical applications, dual-screen displays can be configured with multiple foot pads, multiple bottom grooves, and multiple mounting holes.

[0091] A back cover with a telescopic support is applied to the lower screen body, as shown in the reference. Figure 16 The outer side of the back shell with telescopic foot pads has a support plate groove, and two back shell rotating shafts are arranged in the support plate groove. The other part of the back shell rotating shaft is fixed to the support plate, so that the support plate can rotate relative to the support plate groove. The inner side of the back shell of the telescopic foot pads has a side opposite to the support plate groove, and a part of the back shell rotating shaft is fixed to the inner side of the back shell of the telescopic foot pads. A magnetic attraction mechanism is provided on the support plate, and the back shell with telescopic foot pads has an internal magnetic attraction component. The magnetic attraction mechanism and the internal magnetic attraction component attract each other, so that the support plate can be bound in the support plate groove.

[0092] In practical applications, the height of the foot pad head extending out is greater than the height of the rotating shaft exposed on the side, so that... Figure 27 As shown, when supporting dual monitors from the side, the foot pads directly contact the support platform, improving the stability of the support.

[0093] In practical application, the corresponding foot pad head can be controlled to extend or retract when the pressing protrusion slides in the bottom hole, wherein the foot pad head corresponding to the pressing protrusion refers to the foot pad head closest to the bottom hole where the pressing protrusion is located.

[0094] The utility model provides a double screen display with retractable foot pads, applies the back shell with retractable foot pads, through setting up the pressing protrusion in the bottom hole, can be convenient for user to adjust the retractable foot pad, specifically, user will press the pressing protrusion to push out a distance and then release, can realize the retractable adjustment of foot pad, guarantees the conversion between at least the pop -up foot pad state and the retractable foot pad state, improves the user experience. The back shell with retractable foot pads is applied to display equipment, can satisfy the various needs (for example, the need of supporting of the extended foot pad, the need of supporting of the retracted foot pad) of user to display equipment, improves the user experience. By providing a double screen display with retractable foot pads, since the back shell with retractable foot pads is adopted, the retractable adjustment of foot pad is realized, the problem that the foot pad of display equipment is inconvenient to adjust and retract to adapt to various use scenarios in the prior art is solved. The shaft arranged on the side reduces the gap between the double screens, and the multiple retractable foot pad heads arranged on the side make the double screen display contact the desktop through the extended foot pad when supported by the side, avoiding the influence of the shaft on the stability of support.

[0095] It is obvious for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the utility model is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
