Abstract
Description
Technical Field
[0001] This utility model relates to the field of flat plate shell technology, specifically a hidden pen slot flat plate shell. Background Technology
[0002] A tablet case is a cover or sleeve designed to cover and protect a tablet computer. They are typically made of plastic, rubber, leather, or other durable materials and are designed to prevent the tablet from being scratched, bumped, or otherwise damaged during everyday use.
[0003] Currently, tablet cases cover and protect the tablet during use. However, existing tablet cases usually place the stylus slot on the side of the case, leaving one end of the stylus exposed. When the exposed end is facing down, the stylus may slip and fall, causing damage. Therefore, a tablet case with a hidden stylus slot is designed. Utility Model Content
[0004] In order to solve the above problems, the purpose of this utility model is to provide a concealed pen slot flat shell to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model proposes a concealed pen slot flat shell, including a flat shell body, wherein a mounting groove is provided on one side of the flat shell body;
[0006] The tablet shell body has a placement mechanism on one side, and the placement mechanism includes a placement plate, a mounting plate, a pen slot, a slider, and a slide groove. Two slide grooves are opened on one side of the mounting groove, and sliders are slidably connected to the inner walls of the two slide grooves. A placement plate is fixedly installed on one side of each of the two sliders. A mounting plate is fixedly installed on the bottom of each placement plate. A pen slot is opened on one side of the mounting plate for placing a stylus.
[0007] In one example, the top of the mounting slot has a slot, and three mounting holes are provided on both sides of the inner wall of the slot.
[0008] In one example, telescopic rods are fixedly installed on the inner walls of the six mounting holes, and extrusion plates are fixedly installed on the ends of the six telescopic rods that are close to each other.
[0009] In one example, a fixing plate is fixedly installed on the outer ring of each of the six telescopic rods, and a spring is fixedly installed on the side of each of the six fixing plates that is far apart from each other.
[0010] In one example, the ends of the six springs that are far apart from each other are fixedly connected to the mounting holes.
[0011] In one example, a ventilation groove is provided on one side of the flat shell body, and the ventilation groove is adapted to the ventilation holes of the flat plate.
[0012] In one example, a circular groove is provided on one side of the tablet shell body and on the other side, the circular groove being adapted to the tablet camera card.
[0013] In one example, a push plate is fixedly installed on one side of the front of the card placement plate.
[0014] The concealed pen slot flat shell proposed in this utility model can bring the following beneficial effects:
[0015] 1. This concealed pen slot flat shell, through the cooperation of the placement mechanism and the slot mechanism, when the placement plate moves downward, it drives the mounting plate downward, which in turn drives the slot downward. When the bottom of the mounting plate is in contact with the inner wall of the slot, the placement plate is perfectly matched with the mounting slot, and the mounting plate is perfectly matched with the slot, thus concealing the pen slot.
[0016] 2. When the mounting plate and the slot are matched, the concealed pen slot flat shell will compress the extrusion plate and drive the telescopic rod to move. The spring will be compressed by the fixing plate, so that the spring generates potential energy. When the mounting plate and the slot are in contact, the spring will perform a reset action under the action of potential energy. The fixing plate will drive the telescopic rod to perform a reset action, which will drive the extrusion plate to move towards each other, compress the mounting plate located in the slot, and clamp it firmly to prevent the mounting plate from slipping out of the mounting slot after installation.

[0025] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0026] like Figures 1-6 As shown, an embodiment of this utility model proposes a hidden pen slot flat shell, including a flat shell body 1, and an installation groove 16 is provided on one side of the flat shell body 1.
[0027] The tablet shell body 1 has a placement mechanism on one side, which includes a placement plate 2, a mounting plate 3, a pen slot 4, a slider 9, and a slide groove 10. Two slide grooves 10 are opened on one side of the mounting groove 16. Slider 9 is slidably connected to the inner wall of each of the two slide grooves 10. A placement plate 2 is fixedly installed on one side of each of the two slider 9. A mounting plate 3 is fixedly installed on the bottom of each placement plate 2. A pen slot 4 is opened on one side of the mounting plate 3. The pen slot 4 is used to place a stylus.
[0028] Specifically, the top of the mounting groove 16 is provided with a slot 5, and three mounting holes 8 are provided on both sides of the inner wall of the slot 5, through which the telescopic rod 14 is fixed.
[0029] Specifically, telescopic rods 14 are fixedly installed on the inner walls of the six mounting holes 8, and extrusion plates 6 are fixedly installed on the ends of the six telescopic rods 14 that are close to each other. The extrusion plates 6 and the fixing plates 15 are fixed by the telescopic rods 14, and the extrusion plates 6 firmly clamp the mounting plates 3 in the slots 5.
[0030] Specifically, each of the six telescopic rods 14 has a fixed plate 15 fixedly installed on its outer ring. Each of the six fixed plates 15 has a spring 7 fixedly installed on the side that is far apart from each other. The spring 7 is fixed by the fixed plate 15. The spring 7 performs a reset action under the action of potential energy, which will drive the two compression plates 6 to move.
[0031] Specifically, the ends of the six springs 7 that are far apart from each other are fixedly connected to the mounting holes 8, and the other ends of the springs 7 are fixed through the mounting holes 8.
[0032] Specifically, a ventilation groove 12 is provided on one side of the flat plate shell body 1. The ventilation groove 12 is adapted to the ventilation holes of the flat plate, and the flat plate is ventilated and cooled through the ventilation groove 12.
[0033] Specifically, a circular groove 13 is provided on one side and the other side of the tablet shell body 1. The circular groove 13 is adapted to the tablet camera card and protects the tablet camera through the circular groove 13.
[0034] Specifically, a push plate 11 is fixedly installed on one side of the front of the placement plate 2, and the mounting plate 3 and the push plate 11 are fixed by the placement plate 2.
[0035] Working principle: Place the stylus in the stylus slot 4, then push the push plate 11 downwards, causing the placement plate 2 to move downwards as well. At this time, the slider 9 moves downwards in the slide groove 10, simultaneously causing the mounting plate 3 to move downwards. When the mounting plate 3 moves into the slot 5, it will press the pressing plate 6 and the telescopic rod 14, thus moving the fixing plate 15. When the fixing plate 15 moves, it will press the spring 7, generating potential energy. When the bottom of the mounting plate 3 is in contact with the slot 5, the mounting plate 3 can be hidden, thereby hiding the stylus slot 4. At the same time, the spring 7 performs a reset action under the action of potential energy, and will drive the telescopic rod 14 to perform a reset action through the fixing plate 15, which will drive the pressing plate 6 to move towards the opposite direction, thus firmly clamping the mounting plate 3 and preventing the plate 2 from slipping out of the mounting groove 16 when hidden, thereby better hiding the stylus slot 4.
