DETAILED DESCRIPTION
[0018] The present application will be further described in conjunction with the drawings and specific embodiments. The embodiments of the present application are given for illustration and description only, and are not exhaustive or limiting of the present application. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the present application and its practical application, and to enable others skilled in the art to understand the present application for various embodiments with various modifications as are suited to the particular use contemplated.
[0019] Embodiment: please refer to Figures 1 to 17 , in the embodiment, a tablet computer structure with anti-falling structure is provided, as shown in Figure 1 andFigure 2 As shown, specifically includes a tablet body 1, the upper side of the tablet body 1 is a display screen, and the lower side is a back cover, the display screen of the tablet body 1 is bonded with a screen protection film 3, and the back cover of the tablet body 1 is sleeved with a back cover protective shell 2, which can protect the back cover and the side edge of the tablet body 1. In the present application, the back cover protective shell 2 is a prior art, which is a conventional protective structure, and the specific structure will not be described in detail; The screen protection film 3 bonded on the display screen surface plays a first layer of protection for the display screen of the tablet body 1, such as Figure 3 As shown, in this embodiment, the screen protection film 3 includes a vibration damping layer 31, an energy absorption layer 32 and a scratch-resistant layer 33, wherein the scratch-resistant layer 33 is located at the outermost side, which is combined by sapphire glass and nano microcrystalline ceramic through hot pressing composite process, the scratch-resistant layer 33 as the surface layer is bonded with the energy absorption layer 32 of the intermediate layer through optical glue, and the energy absorption layer 32 is composed of a flexible OLED substrate and an aerogel layer, the flexible OLED substrate as a support layer, and a honeycomb-shaped hole is formed on it, and the aerogel layer is arranged in the hole to form a honeycomb-shaped aerogel structure, the aerogel is filled in the gap of the flexible OLED substrate, and the aerogel is fixed in the honeycomb structure of the flexible OLED substrate by vacuum adsorption, and forms a physical lock with the surface layer and the vibration damping layer 31 as the bottom layer, the vibration damping layer 31 is specifically a viscoelastic silicone damping glue, which is bonded with the display screen body by UV curing glue; The scratch-resistant layer 33 as the surface layer, wherein the sapphire glass and ceramic composite layer can resist daily scratches, and the hardness is higher than that of ordinary glass. When a sharp object impacts, the surface layer will preliminarily disperse the point impact force, the intermediate layer aerogel will absorb high-frequency impact energy through the micro-porous structure compression deformation, the flexible OLED substrate can prevent brittle fracture, and the damping glue of the bottom layer will dissipate the remaining energy through viscoelastic deformation, reduce the vibration amplitude of the display screen inside, realize the energy attenuation step by step, and protect the display screen. As Figure 2 And Figure 4As shown in the drawings, the front and back of the display screen on the upper end of the tablet computer body 1 are both provided with anti-falling mechanisms 4, the two anti-falling mechanisms 4 are embedded in the side wall of the tablet computer body 1, when the tablet computer body 1 is detected to fall, the two anti-falling mechanisms 4 are activated, and are popped out from the inner wall of the tablet computer body 1 and are unfolded, the unfolded two anti-falling mechanisms 4 can cover the display screen (i.e. the screen protection film 3), so that the display screen is prevented from touching other objects when falling, for example, when the tablet computer body 1 falls, it may touch the corner of a table or a ground protrusion, etc., in this case, the display screen of the tablet computer can be greatly damaged, and the screen protection film 3 alone cannot completely play a protection role, therefore, the two anti-falling mechanisms 4 are arranged in the present application, and the protection effect is increased on the basis of the screen protection film 3, so that complete protection is achieved, if a sharp object is touched when falling, the two anti-falling mechanisms 4 which form a cover structure after unfolding will contact the sharp object, so that the sharp object is prevented from contacting the screen protection film 3, even if the sharp object acts on the screen protection film 3 again after acting on the anti-falling mechanism 4, the anti-falling mechanism 4 has already consumed most of the acting force, and the protection of the screen protection film 3 is further provided, so that the display screen is not damaged, and the protection effect is good. Furthermore, in the present application, in addition to the protection of the screen protection film 3 and the anti-falling mechanism 4, the protection cavity 5 is formed between the protection cover formed by the two unfolded anti-falling mechanisms 4 and the screen protection film 3, as shown in Figure 5 and Figure 6 The protection cavity 5 is a hollow structure, when the tablet computer falls and touches a sharp object, even if the sharp object damages the anti-falling mechanism 4, the protection cavity 5 can isolate the sharp object and the screen protection film 3, so that a distance is formed between the sharp object and the screen protection film 3, and a blocking effect is achieved, so that the screen protection film 3, the protection cavity 5 and the anti-falling mechanism 4 cooperate to play a three-layer protection effect, and the display screen is protected in all directions, compared with the one-layer protection effect of the screen protection film 3 of the display screen of the current tablet computer, the protection scheme of the present application can significantly improve the protection effect of the display screen, and the problem that the display screen is broken by a point impact force penetrating the protection film is avoided; In the present embodiment, the specific structure of the tablet computer body 1 is as follows, as shown in Figure 4 , Figure 5 , Figure 7 and Figure 15As shown, the side wall of the tablet computer body 1 is provided with two recesses 11 symmetrical in front and back, the anti-falling mechanism 4 after being folded is installed in the recess 11, and a controller 6 is further arranged below the anti-falling mechanism 4 in the recess 11. The controller 6 serves as a trigger of the anti-falling mechanism 4. When the tablet computer falls, the controller 6 can detect whether the tablet computer is in a falling state. The anti-falling mechanism 4 can slide in the recess 11. The recess 11 hides and limits the anti-falling mechanism 4. When the controller 6 detects that the tablet computer falls, it controls the anti-falling mechanism 4 to start, so that the anti-falling mechanism 4 pops out of the recess 11 and unfolds, and then the two anti-falling mechanisms 4 cooperate to form a protective cover to protect the display screen. As shown in the figure, Figure 7 The controller 6 includes a control panel 61, a sensor array 62, an electromagnet 63 and a chargeable module 64. The control panel 61, the sensor array 62, the electromagnet 63 and the chargeable module 64 are all installed on the bottom end wall of the recess 11. The electromagnet 63 is located at the center of the recess 11 and magnetically interacts with the anti-falling mechanism 4. The chargeable module 64 is arranged on one side of the electromagnet 63, and the control panel 61 and the sensor array 62 are arranged on the other side. The control panel 61 is provided with a chip that has a control effect on the anti-falling mechanism 4. The control panel 61 is connected with the sensor array 62. The sensor array 62 includes an acceleration sensor, a gravity sensor and a gyroscope. The acceleration sensor, the gravity sensor and the gyroscope work together to transmit specific postures to the control panel 61. The control panel 61 can analyze the motion state of the device and then detect whether the tablet computer falls. When the device freely falls, the resultant acceleration tends to be zero (weightless state). At this time, the acceleration sensor can detect a value close to zero. The gyroscope can detect whether the tablet computer is turned over or rotated (for example, the device may roll in the air when falling). The gravity sensor is used to judge the posture of the device when it is stationary or to assist in distinguishing gravity from other accelerations in motion. The specific working states of the three are combined with each other to analyze whether the tablet computer is in a falling state. The specific analysis algorithm is the prior art and can be achieved by using the existing technology. The controller 6 is used as a trigger and is not the focus of improvement of the present application. For example, almost all current smart phones have a falling detection function and can issue a warning to remind the user. The chargeable module 64 supplies power to the controller 6. The chargeable module 64 is connected with the battery of the tablet computer. The battery of the tablet computer can charge the chargeable module 64 to ensure that the chargeable module 64 has sufficient power and can always be in a working state. When the chargeable module 64 supplies power to the electromagnet 63, the electromagnet 63 generates magnetism. According to the direction of the current, the electromagnet 63 will either be attracted to and fixed with the anti-falling mechanism 4 or repel the anti-falling mechanism 4 to pop it out of the recess 11; When the controller 6 detects that the tablet computer is falling, the electromagnet 63 generates a repulsive force with the anti-falling mechanism 4, so that the anti-falling mechanism 4 is instantly popped out of the groove 11, thereby the anti-falling mechanism 4 can be unfolded to protect the display screen, otherwise, the anti-falling mechanism 4 can be retracted after use, and it is pressed into the groove 11 again, at this time, the electromagnet 63 generates an attractive force with the anti-falling mechanism 4 to fix the anti-falling mechanism 4 in the groove 11, so that it is hidden in the groove 11 when not in use, and does not affect the normal use of the tablet computer; The specific structure of the anti-falling mechanism 4 is shown in Figure 5 and Figure 8 , which comprises a hidden warehouse 41 and an unfolding structure 42, the hidden warehouse 41 is located in the groove 11, and the unfolding structure 42 is placed in the hidden warehouse 41 when retracted, and the unfolding structure 42 is automatically unfolded to form a protective cover structure after the hidden warehouse 41 is popped out of the groove 11; As shown in Figure 8 , Figure 9 and Figure 16 , the hidden warehouse 41 comprises a warehouse body 411, the inside of the warehouse body 411 is a hidden cavity for accommodating the unfolding structure 42, and the left and right sides of the warehouse body 411 are provided with sliding blocks 414, the sliding blocks 414 are located in the side grooves 12 opened in the left and right side walls of the groove 11, and are slidably connected with each other to limit the warehouse body 411, so that the warehouse body 411 can only vertically slide upward or downward in the groove 11, and remains stable movement; A permanent magnet 416 is arranged at the bottom center of the warehouse body 411, the permanent magnet 416 interacts with the electromagnet 63, repels each other when the magnetic poles of the two are the same, at this time, the warehouse body 411 can be popped out of the groove 11, otherwise, when the magnetic poles between the two are opposite, the warehouse body 411 can be embedded into the groove 11 and fixed by the magnetic attraction force, so that it is stably placed; In order to make the warehouse body 411 pop out instantly, the warehouse body 411 is also provided with force storage springs 415, in the embodiment, the force storage springs 415 are provided with two, which are symmetrically arranged about the center of the warehouse body 411, when the warehouse body 411 is placed in the groove 11, the force storage springs 415 are squeezed to store energy, so that when the warehouse body 411 needs to be popped out, the elastic force cooperates with the repulsive force between the permanent magnet 416 and the electromagnet 63 to pop out the warehouse body 411 at the fastest speed; A through groove 412 is opened in the side wall of the warehouse body 411 close to the display screen, the through groove 412 is a character-shaped structure, the edge of the through groove 412 is treated with a round corner, and meanwhile, a bottom groove 413 is arranged at the bottom of the left and right ends of the through groove 412, the through groove 412 and the bottom groove 413 are combined into a slide, so that the unfolding structure 42 can slide out of the slide to unfold; After the anti-falling mechanism 4 is unfolded, in order to also protect the warehouse body 411 and avoid that the warehouse body 411 has a stress effect on the tablet computer after being stressed, as shown in Figure 12As shown, the side wall of the bin body 411 is provided with a honeycomb structure 417, and the honeycomb structure 417 is filled with non-Newtonian fluid material, and the surface of the bin body 411 is covered with a wear-resistant layer to increase wear resistance, and when the bin body 411 is impacted, it can harden to disperse point pressure, thereby achieving a protective effect. The specific structure of the unfolding structure 42 in the anti-falling mechanism 4 is shown in Figure 8 、 Figure 9 、 Figure 10 、 Figure 13 、 Figure 14 and Figure 17 , which includes an air bag 421, a pull plate 422, a micro air pump 423, and a sliding seat 425. One end of the air bag 421 is located in the hidden cavity, and the other end is fixed to the side wall of the pull plate 422. The pull plate 422 is adapted to the through groove 412. After the air in the air bag 421 is exhausted, it can be stored in the hidden cavity, and at the same time, the pull plate 422 is placed in the through groove 412. The pull plate 422 can just seal the through groove 412, and the left and right ends of the bottom of the pull plate 422 are provided with sliding seats 425. The cross section of the sliding seat 425 is the same as the bottom groove 413. In the inactive state, the sliding seat 425 is retracted in the hidden cavity through the bottom groove 413. The sliding seat 425 and the inner wall of the hidden cavity in the bin body 411 are provided with an extrusion spring 426. One end of the extrusion spring 426 is connected to the inner wall of the hidden cavity, and the other end is placed in the through hole opened in the sliding seat 425. The extrusion spring 426 can drive the sliding seat 425 to slide in the guide groove 13 opened on the upper surface of the tablet computer body 1. As shown in Figure 15 , the guide groove 13 is provided with two left and right symmetrical ones. The left and right ends of the sliding seat 425 move in the corresponding guide groove 13. After the bin body 411 is popped out of the groove 11, the pull plate 422 and the sliding seat 425 are no longer limited by the inner wall of the groove 11, so under the action of the extrusion spring 426, the sliding seat 425 will be pushed to slide in the guide groove 13 towards the center of the display screen. The sliding of the sliding seat 425 will drive the pull plate 422 to move, so as to pull out the air bag 421 from the hidden cavity and make it unfold; During the unfolding process, the micro air pump 423 inflates the air bag 421, making it gradually bulge. The micro air pump 423 is installed in the groove 11 and communicates with the air bag 421 through a hose. The inflation of the air bag 421 by the micro air pump 423 makes it swell, thereby playing a buffering and protective role. During the inflation process, the pull plate 422 will pull it to move, so that it inflates and unfolds at the same time. Moreover, Figure 10 and Figure 11As shown, a plurality of pull ropes 427 are distributed on the inner wall of the air bag 421, one end of the pull rope 427 is connected to the end of the air bag 421, the other end is fixed on the pull plate 422, and each pull rope 427 is fixed and attached to the inner wall of the air bag 421. When the pull plate 422 pulls the air bag 421 to unfold, under the restriction and guidance of the pull rope 427, the air bag 421 can be inflated and unfolded into a nearly planar structure, and at the same time, it can be more uniform on the surface of the display screen after unfolding, avoiding the occurrence of local unevenness or local non-inflation. After use, the pull rope 427 can be stored in the hidden cavity together with the air bag 421 again, and can be used continuously next time; In order to better seal and form a protective cover when the two anti-falling mechanisms 4 are closed, a plurality of connecting pieces 424 are embedded on the side of the pull plate 422 away from the air bag 421. It should be noted that the connecting pieces 424 in the inner walls of the two pull plates 422 are made of different materials. One of the connecting pieces 424 on one of the pull plates 422 is a magnet piece, and the other is an iron piece. Conversely, the same applies. The purpose is to make the two pull plates 422 closer to each other, which can help to close the protective cover and form a protective cover. At the same time, after mutual contact and sticking, gaps are avoided, and the protection effect is improved. When the anti-falling mechanism 4 completes a protection function, the air bag 421 is deflated, and then the two pull plates 422 are separated, and the pull rope 427 and the air bag 421 are stored in the storage cavity 411. During this process, the pull plate 422 and the sliding seat 425 are pushed to move and are also stored in the hidden cavity. Then the magnetism of the electromagnet 63 is changed to be able to attract the permanent magnet 416, and the storage cavity 411 is pressed into the groove 11 and is magnetically attracted and fixed. When the next falling danger occurs, it can be popped out again for protection.
