Description

Technical Field

[0001] The invention relates to the technical field of industrial flat panels, in particular to an emergency explosion-proof protection structure of an industrial flat panel and a method thereof. Background Art

[0002] A tablet computer, also called a portable computer, is a small, easy-to-carry personal computer that uses a touch screen as the basic input device. An industrial tablet computer is an industrial control computer designed for industrial use. Its basic performance and compatibility are similar to those of commercial computers, but industrial tablet computers focus more on stability and reliability in different environments.

[0003] In order to prevent the tablet computer from being damaged when it falls accidentally, a protective case is generally placed on the outside of the tablet, but most protective cases cannot protect the screen. Even if there is a flip protective case that can protect the screen, it cannot prevent the accidental fall when the screen is exposed. Based on this, protective devices with airbags and gravity sensors have appeared on the market. However, due to the high sensitivity of the gravity sensor and the fact that the use range of industrial tablets may extend to outdoor areas and need to be carried and moved, it is difficult to distinguish whether it is an accidental fall or the user moving the tablet, and there is a risk of accidental touch. For this reason, we propose an emergency explosion-proof protection structure and method for industrial tablets. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] See also Figure 1-11 The present invention provides a technical solution: an emergency explosion-proof protection structure of an industrial tablet and a method thereof, comprising a tablet body 1 and a protective shell 2 sleeved on the outside of the tablet body 1, and also comprising a gripping sleeve 3 arranged on the back side of the protective shell 2, wherein a mobile switch 4 is movably arranged in the gripping sleeve 3, and when holding the gripping sleeve 3, the palm can squeeze the mobile switch 4 to move it, and expansion members 5 are arranged on both sides of the protective shell 2, which can expand above the screen to form a protective structure when the tablet falls accidentally, and a trigger member 6 is arranged in the protective shell 2, which is driven to move by the mobile switch 4, thereby triggering the expansion member 5 to expand it, and limiting members 7 are also arranged on both sides of the protective shell 2, which can limit the contact between the mobile switch 4 and the trigger member 6, thereby preventing the expansion member 5 from being triggered:

[0041] The holding cover 3 is rotatably arranged on the back side of the protective shell 2. When in use, the palm is inserted into the holding cover 3, which can conveniently and labor-savingly pick up the tablet for operation, and the holding cover 3 is set to rotate, which can facilitate the horizontal or vertical operation of the tablet. The holding cover 3 and the back side of the protective shell 2 are both provided with through grooves, and the holding cover 3 is provided with a mounting groove 41. The mobile switch 4 includes a moving block 42 movably arranged in the mounting groove 41. The bottom of the moving block 42 is fixedly connected to a mounting spring 43, and the bottom of the mounting spring 43 is fixedly connected to the bottom of the mounting groove 41. When the palm is inserted into the holding cover 3, the palm will squeeze the moving block 42 to move it. A fixing cylinder 44 is fixedly arranged at the bottom of the moving block 42, and a hollow cone 45 is fixedly arranged on the fixing cylinder 44. The cross-section between the fixing cylinder 44 and the hollow cone 45 is in the shape of a hook.

The expansion member 5 includes an airbag 53 provided in the placement groove 51. The airbag 53 is cylindrical. When the airbag 53 expands, the cover plate 52 will be pushed open to form a cylindrical airbag 53. The placement groove 51 is inclined on the protective shell 2 and the opening faces the screen side, so that the expanded multiple cylindrical airbags 53 abut against each other to form a protective structure. A gas generating assembly 8 is provided in the protective shell 2. The gas generating assembly 8 is connected to the placement groove 51 and can transport gas into the airbag 53 to expand it.

[0043] A fixing groove 81 is provided at the bottom of the protective shell 2, and a connecting channel is provided between the fixing groove 81 and the placement groove 51. The gas generating assembly 8 includes a placement tube 82 arranged in the fixing groove 81, and a plurality of placement holes 83 are provided in the placement tube 82. A raw material block 84 is provided in the placement hole 83. After the raw material block 84 is decomposed, a large amount of gas is generated to fill the airbag 53. In the present embodiment, the raw material block 84 is sodium azide NaN3, which can generate a large amount of ammonia when decomposed. A spark plug is fixedly provided at the bottom of the placement tube 82, and the spark plug extends into the placement hole 83 to contact with the raw material block 84. A conductive plate 85 electrically connected to the spark plug is provided on the side wall of the fixing groove 81. When the conductive plate 85 is energized, the spark plug can be started to ignite the raw material block 84.

[0044] A rotating disk 86 is rotatably provided at the notch position of the fixed groove 81, and a supporting spring 87 is fixedly provided on the side wall of the fixed groove 81.

A slot 89 for use with the insertion rod 88 is opened on the placement tube 82. In the present embodiment, the insertion rod 88 and the slot 89 are both set to be hexagonal. When the rotating disk 86 is pressed, the insertion rod 88 can be driven to be plugged into the slot 89, and then the rotating disk 86 can be rotated to drive the placement tube 82 to rotate, so that the placement hole 83 with the raw material block 84 is aligned with the connecting channel.

[0045] A winding groove 9 is opened in the protective shell 2, and a winding shaft 10 is rotatably arranged in the winding groove 9. A reel 11 is fixedly arranged on the outside of the winding shaft 10. A knob 12 is fixedly connected to the end of the winding shaft 10. A connecting rope 13 is arranged on the outside of the reel 11. The two ends of the connecting rope 13 are respectively fixedly connected to the reel 11 and the top of the airbag 53. When the airbag 53 is inflated, the reel 11 can be used to rewind the connecting rope 13 to recover it, and it can be placed in the placement groove 51 again.

[0046] Side grooves 61 are provided on both sides of the middle of the protective shell 2, and the side grooves 61 are connected with the through grooves. The trigger member 6 includes a trigger rod 62 movably arranged in the side grooves 61, and the end of the trigger rod 62 extends into the through groove and the end is an inclined surface. A reset spring 63 is fixedly connected to the bottom of the trigger rod 62, and the two ends of the reset spring 63 are respectively fixedly connected to the trigger rod 62 and the bottom of the side groove 61. A rubber block 64 is fixedly arranged below the trigger rod 62, and a conductive block 65 is arranged below the trigger rod 62 and in the side groove 61. The conductive block 65 located on the side groove 61 is electrically connected to the conductive plate 85, and the conductive block 65 arranged on the trigger rod 62 is electrically connected to the external power supply. A power supply and a controller are arranged in the protective shell 2, both of which are prior arts and will not be described in detail here.

[0047] When the moving block 42 moves, the hollow cone 45 can be driven to move. The hollow cone 45 moves to squeeze the inclined surface at the end of the trigger rod 62 to make it move. However, when the hollow cone 45 moves past the position of the trigger rod 62, the trigger rod 62 is reset. When the hollow cone 45 is reset, the edge of the hollow cone 45 will press against the trigger rod 62 to make it rotate, thereby making the two conductive blocks 65 contact and energize, causing the airbag 53 to expand.

[0048] The limiting member 7 includes a limiting plate 71 slidably arranged on both sides of the protective shell 2, a guide rod 72 is fixedly arranged on the limiting plate 71, and a guide spring 73 is fixedly connected to the end of the guide rod 72, and the two ends of the guide spring 73 are respectively connected to the guide rod 72 and the protective shell 2, and a cavity is also opened in the protective shell 2, and the cavity is located on the back side of the side groove 61, and a limiting rod 74 is fixedly arranged on the limiting plate 71, and the limiting rod 74 movably penetrates the protective shell 2 and the end thereof extends into the cavity, and a pull rope 75 is fixedly connected to the bottom end of the trigger rod 62, and one end of the pull rope 75 is fixedly connected to the limiting rod 74, and a cross bar 76 is fixedly arranged in the cavity, and the pull rope 75 bypasses the cross bar 76 and is connected to the guide rod 72;

[0049] When the limiting plate 71 drives the limiting rod 74 to move, the limiting rod 74 will pull the pull rope 75, and the pull rope 75 will pull the trigger rod 62 to drive it to move. In this way, when the hollow truncated cone 45 is reset, the hollow truncated cone 45 will not hook the trigger rod 62, and then the airbag 53 will not be triggered.

[0050] In summary, when in use, the user inserts his hand into the grip sleeve 3, and at this time, the palm squeezes the moving block 42 to move it, and the moving block 42 drives the hollow truncated cone 45 to move, and the hollow truncated cone 45 moves to squeeze the inclined surface at the end of the trigger rod 62 to move it, but when the hollow truncated cone 45 moves past the position of the trigger rod 62, the trigger rod 62 is reset, and when not in use, the tablet is held with the other hand, and this hand squeezes the limit plate 71, and the limit plate 71 drives the limit rod 74 to move, and the limit rod 74 pulls the pull rope 75, and the pull rope 75 pulls the trigger rod 62 to drive it to move, so that when the hollow truncated cone 45 is reset, the hollow truncated cone 45 will not hook the trigger rod 62, and then the airbag 53 will not be triggered;

[0051] However, when the hand is accidentally released, the limit rod 74 does not work. When the hollow cone 45 is reset, the edge of the hollow cone 45 will press against the trigger rod 62 to make it rotate, so that the two conductive blocks 65 are in contact and energized, causing the airbag 53 to expand.

[0052] An emergency explosion-proof protection method for an industrial flat panel, the steps are as follows:

[0053] S1: When using the tablet, insert the palm into the grip sleeve 3 to squeeze the moving block 42 to drive the hollow truncated cone 45 to move, and the hollow truncated cone 45 squeezes the trigger rod 62 to move it. When the tablet accidentally falls out of the hand, the hollow truncated cone 45 returns to its original position, and its edge will hook the trigger rod 62 to compress the rubber block 64;

[0054] S2: The trigger rod 62 rotates to make the two conductive blocks 65 contact;

[0055] S3: The conductive plate 85 is energized to start the spark plug and emit an electric spark toward the placement hole 83 connected thereto;

[0056] S4: The raw material block 84 is ignited and decomposed to generate a large amount of gas, which causes the airbag 53 to expand and extend to protect the screen of the tablet.

[0057] Embodiment 2:

[0058] See also Figure 12-13 The second embodiment has the same main structure as the first embodiment, except that both ends of the protective shell 2 are provided with air jets 14, both ends of the protective shell 2 are provided with placement tubes 82, the bottom of the placement tube 82 is provided with a spark plug, a raw material block 84 is provided in the placement tube 82, a rotating disk 86 is provided at the bottom of the placement tube 82, and the air jets 14 are connected to the placement tube 82, a level sensor is provided in the protective shell 2, and the level sensor is electrically connected to the spark plug;

[0059] The structures of the placement cylinder 82 and the rotating disk 86 are the same as those in the first embodiment. When the flat plate falls accidentally, the horizontal sensor can detect the orientation of the two ends of the flat plate, so that the raw material block 84 at one of the two ends is ignited to spray gas, so that the lower end of the protective shell 2 sprays gas downward, and then the flat plate is adjusted to be almost horizontal, so that the protective shell 2 touches the ground first instead of the corners, and the flat plate can be effectively protected.
