Description

Technical Field

[0001] The utility model belongs to the technical field of tablet computers, and in particular relates to a mainboard installation structure inside a tablet computer. Background Art

[0002] A tablet computer, also called a portable computer, is a small, portable personal computer that uses a touch screen as a basic input device.

[0003] For example, a Chinese patent with publication number CN214704492U discloses a 5G tablet computer motherboard mounting structure, which relates to the technical field of tablet computer motherboard mounting structure. It is composed of a tablet shell, a back shell, a motherboard, a fixing groove, a protrusion, a mounting groove and a fixing mechanism. The back of the tablet shell is provided with a back shell, the surface of the back shell is provided with a motherboard, both sides of the back shell are provided with fixing grooves, the surface of the tablet shell is provided with a protrusion, the interior of the protrusion is provided with a mounting groove, and the surface of the mounting groove is provided with a fixing mechanism. In actual use, by setting the mounting device, when it is necessary to combine the tablet shell and the back shell for installation, it is only necessary to simply operate the mounting block to avoid the situation where the back shell is damaged due to excessive force when the bolts are tightened. At the same time, when the back shell needs to be disassembled, it is only necessary to turn the back shell downward and pull the mounting blocks on both sides at the same time. The operation is very simple and convenient, which is conducive to actual use.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the device only needs to pull two mounting blocks to install and remove, and the process is relatively simple. Some young and naughty children are likely to pull the two mounting blocks to remove the back cover when playing, and the back cover is likely to hit the motherboard and damage it after being removed. In addition, when the device is accidentally dropped on the ground during use, it cannot cushion the motherboard, which is likely to cause damage to the motherboard, and the cost of repair is high. In view of this, we propose a motherboard installation structure inside a tablet computer. Utility Model Content

[0006] The purpose of the utility model is to provide a mainboard installation structure inside a tablet computer to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a mainboard installation structure inside a tablet computer, comprising:

[0008] A flat shell, three damping rods are fixedly installed on the inner walls of the four sides of the inner cavity of the flat shell, one end of the three damping rods is fixedly installed with the same U-shaped plate, a buffer pad is fixedly installed in the U-shaped plate, a spring is sleeved on the damping rod, the four buffer pads are provided with the same main board, the top and bottom of the main board and the buffer pad are fixedly installed with a heat insulation layer, the top of the flat shell and the positions close to the four corners are provided with limiting grooves, the top of the flat shell is provided with a rear shell, the bottom of the rear shell and the positions close to the four corners are fixedly installed with plug blocks, and the plug blocks are located in the corresponding limiting grooves;

[0009] Four fixing components are located in the flat shell and are used to fix the four plug-in blocks respectively.

[0010] The U-shaped plates are then pressed down to push the mainboard downwards, and the four U-shaped plates are squeezed away from each other by the mainboard. At this time, the damping rod and the second spring are squeezed by the U-shaped plates and will shrink until the mainboard moves downwards into the four buffer pads. Then, under the action of the rebound force of the second spring, the second spring will reset the U-shaped plate. At this time, the damping rod will also reset, so that the mainboard is fixed by the four U-shaped plates. Then, the staff places the four plug-in blocks at the bottom of the rear shell just above the corresponding limit grooves, and then presses the rear shell downwards. The rear shell will drive the four plug-in blocks to move downwards in the corresponding limit grooves until the bottom of the plug-in blocks contacts the bottom of the limit grooves. At this time, through the four fixing components set, the fixing components will fix the plug-in blocks in the corresponding limit grooves, so that the rear shell will be fixed on the flat shell.

[0011] When the whole device accidentally falls on the ground during use, the mainboard will shake and move due to the impact. At this time, the mainboard will drive the corresponding buffer pad to move, and the buffer pad will drive the U-shaped plate to move. The U-shaped plate will squeeze the damping rod to shrink. At the same time, the spring will shrink when it is squeezed. Under the damping action of the damping rod, the force exerted on the U-shaped plate can be buffered. Moreover, under the action of the rebound force of the spring, the U-shaped plate can be reset. The U-shaped plate will reset the buffer pad, so that the force generated by the impact on the mainboard can be buffered to avoid damage to the mainboard. Under the action of the buffer pad, the mainboard can be buffered at any angle when the whole device falls, effectively avoiding damage to the mainboard.

[0012] When disassembling, first fix the tablet shell and make the back shell face downward. Use the four fixing components to release the fixation of the plug-in block. Then, the back shell will fall under the action of gravity. At this time, the back shell is separated from the tablet shell. Then the four U-shaped plates can be moved away from each other. Then, the mainboard will no longer be fixed by the four U-shaped plates and can be disassembled.

[0013] In the above technical solution, further, the fixing assembly includes:

[0014] The slide groove is opened in the flat shell and is located on one side of the limit groove. The slide groove is connected with the limit groove. A U-shaped rod is slidably installed in the slide groove. One side of the U-shaped rod is fixedly installed with a plurality of springs fixed to the inner wall of the slide groove. A groove is opened on the plug block. The groove is connected with the slide groove. One end of the U-shaped rod extends into the groove. The other end of the U-shaped rod is opened with a round hole.

[0015] In the present technical scheme, when installing the back shell, the staff places the four plug-ins at the bottom of the back shell just above the corresponding limit grooves, and then presses the back shell downward, and the back shell will drive the four plug-ins to move downward in the corresponding limit grooves. When the bottom of the plug-in block contacts one end of the U-shaped rod, because one end of the U-shaped rod is an inclined structure, under the action of the extrusion force of the plug-in block, one end of the U-shaped rod is squeezed and displaced. At this time, spring two will shrink due to the squeezing of the U-shaped rod, and the plug-in block will continue to move downward until the bottom of the plug-in block contacts the bottom of the limit groove. Then, under the action of the rebound force of several springs two, several springs two will push the U-shaped rod to move, so that one end of the U-shaped rod enters the groove on the plug-in block, thereby fixing the plug-in block in the corresponding limit groove. At the same time, the remaining plug-ins will be fixed in the corresponding limit grooves, so that the back shell will be fixed on the flat shell.

[0016] In the above technical solution, further, one end of the U-shaped rod is plugged into the groove, and one end of the U-shaped rod is in an inclined structure.

[0017] In this technical solution, it is ensured that one end of the U-shaped rod can be inserted into the groove; one end of the U-shaped rod is in an inclined structure, and under the action of the extrusion force of the insert block, one end of the U-shaped rod is squeezed and displaced.

[0018] In the above technical solution, further, the thermal insulation layer is in contact with the buffer pad.

[0019] In this technical solution, it is ensured that the thermal insulation layer can insulate the buffer pad.

[0020] In the above technical solution, further, two ends of the spring 1 are tightly welded to the inner wall of the flat shell and the other side of the U-shaped plate respectively, and the top of the U-shaped plate is an inclined structure.

[0021] In this technical solution, the structural stability of the spring 1 is ensured during operation; the top of the U-shaped plate is an inclined structure, and installation can be performed by simply pressing down the main board.

[0022] In the above technical solution, further, the insert block is plug-fitted into the limiting groove.

[0023] In this technical solution, it is ensured that the insert block can be inserted into the limiting groove.

[0024] The beneficial effects of the utility model are:

[0025] 1. The internal motherboard installation structure of the tablet computer can provide all-round buffering for the motherboard when the entire device accidentally falls to the ground during use through the cooperation of the buffer pad, U-shaped plate, damping rod and spring, ensuring that the internal motherboard will not be damaged when the entire device falls to the ground.

[0026] 2. The internal motherboard mounting structure of the tablet computer ensures that the back cover can be fixed on the tablet shell through the cooperation of the set limit slots, plug-in blocks, round holes and fixing components. When removing the back cover, a card removal pin is required to remove the back cover, which effectively prevents some smaller children from easily opening the back cover.

[0044] When installing and using, the staff first places the main board 4 just above the four U-shaped plates 9, and then presses the main board 4 downward. Because the top of the U-shaped plate 9 is an inclined structure, when the main board 4 is pressed downward, the main board 4 will squeeze the four U-shaped plates 9 away from each other. At this time, the damping rod 10 and the second spring 14 will shrink due to the squeezing of the U-shaped plate 9 until the main board 4 moves downward into the four buffer pads 5. Then, under the action of the rebound force of the second spring 14, the second spring 14 will reset the U-shaped plate 9 At this time, the damping rod 10 will also be reset, so that the mainboard 4 is fixed by the four U-shaped plates 9.

Then, the rear shell 2 is pressed downward, and the rear shell 2 will drive the four plug-in blocks 3 to move downward in the corresponding limit slots 7 until the bottom of the plug-in blocks 3 contacts the bottom of the limit slots 7. At this time, through the four fixed components, the fixed components will fix the plug-in blocks 3 in the corresponding limit slots 7, so that the rear shell 2 will be fixed on the flat shell 1;

[0045] When the whole device accidentally falls on the ground during use, the main board 4 will shake and move when it is hit. At this time, the main board 4 will drive the corresponding buffer pad 5 to move, and the buffer pad 5 will drive the U-shaped plate 9 to move. The U-shaped plate 9 will squeeze the damping rod 10 to shrink. At the same time, the spring 11 will shrink when it is squeezed. Under the damping action of the damping rod 10, the force exerted on the U-shaped plate 9 can be buffered. Moreover, under the action of the rebound force of the spring 11, the U-shaped plate 9 can be reset. The U-shaped plate 9 will reset the buffer pad 5, so that the force generated by the impact on the main board 4 can be buffered to avoid damage to the main board 4.

Then, the rear shell 2 will fall under the action of gravity. At this time, the rear shell 2 is separated from the tablet shell 1, and then the four U-shaped plates 9 can be moved away from each other. Then, the main board 4 will no longer be fixed by the four U-shaped plates 9 and can be disassembled.

A round hole 15 is opened at the other end of the U-shaped rod 12.

[0050] When the bottom of the plug block 3 contacts with one end of the U-shaped rod 12, because one end of the U-shaped rod 12 is in an inclined structure, under the action of the extrusion force of the plug block 3, one end of the U-shaped rod 12 is squeezed and displaced. At this time, the spring 2 14 is squeezed by the U-shaped rod 12 and will shrink. The plug block 3 continues to move downward until the bottom of the plug block 3 contacts the bottom of the limiting groove 7. Subsequently, under the action of the rebound force of the springs 2 14, the springs 2 14 will push the U-shaped rod 12 to move, so that one end of the U-shaped rod 12 enters the groove 8 on the plug block 3, thereby fixing the plug block 3 in the corresponding limiting groove 7. At the same time, the remaining plug blocks 3 will be fixed in the corresponding limiting grooves 7, so that the back shell 2 will be fixed on the flat shell 1.

[0062] Here, it is ensured that the insert block 3 can be inserted into the limiting groove 7 .

[0063] Working principle: during installation and use, the staff first places the main board 4 directly above the four U-shaped plates 9, and then the staff presses the main board 4 downward. Because the top of the U-shaped plate 9 is an inclined structure, when the main board 4 is pressed downward, the main board 4 will squeeze the four U-shaped plates 9 away from each other. At this time, the damping rod 10 and the second spring 14 will shrink due to the squeezing of the U-shaped plate 9 until the main board 4 moves downward into the four buffer pads 5. Then, under the action of the rebound force of the second spring 14, the second spring 14 will reset the U-shaped plate 9. At this time, the damping rod 10 will also reset, so that the main board 4 is fixed by the four U-shaped plates 9. Then, the staff places the four plugs 3 at the bottom of the rear shell 2 directly above the corresponding limit slots 7, and then presses the rear shell 2 downward, and the rear shell 2 will bring The four plug blocks 3 are moved downward in the corresponding limiting grooves 7. When the bottom of the plug block 3 contacts one end of the U-shaped rod 12, because one end of the U-shaped rod 12 is in an inclined structure, under the action of the extrusion force of the plug block 3, one end of the U-shaped rod 12 is squeezed and displaced. At this time, the second spring 14 is squeezed by the U-shaped rod 12 and will shrink, and the plug block 3 continues to move downward until the bottom of the plug block 3 contacts the bottom of the limiting groove 7. Subsequently, under the action of the rebound force of the second springs 14, the second springs 14 will push the U-shaped rod 12 to move, so that one end of the U-shaped rod 12 enters the groove 8 on the plug block 3, thereby fixing the plug block 3 in the corresponding limiting groove 7. At the same time, the remaining plug blocks 3 will be fixed in the corresponding limiting grooves 7, so that the rear shell 2 will be fixed on the flat shell 1;

[0064] When the whole device accidentally falls on the ground during use, the main board 4 will shake and move when it is hit. At this time, the main board 4 will drive the corresponding buffer pad 5 to move, and the buffer pad 5 will drive the U-shaped plate 9 to move. The U-shaped plate 9 will squeeze the damping rod 10 to shrink. At the same time, the spring 11 will shrink when it is squeezed. Under the damping action of the damping rod 10, the force exerted on the U-shaped plate 9 can be buffered. Moreover, under the action of the rebound force of the spring 11, the U-shaped plate 9 can be reset. The U-shaped plate 9 will reset the buffer pad 5, so that the force generated by the impact on the main board 4 can be buffered to avoid damage to the main board 4. Under the action of the buffer pad 5, the main board 4 can be buffered at any angle when the whole device falls, effectively avoiding damage to the main board 4.

[0065] When disassembling, first fix the tablet shell 1 and make the back shell 2 face downward. Then, two staff members use the card removal pin to make one end of the card removal pin enter the round hole 15. Then, press the card removal pin to make the card removal pin move against the U-shaped rod 12. At this time, the plurality of springs 14 will be squeezed and will shrink until one end of the U-shaped rod 12 is moved out of the groove 8. At the same time, the other ends of the U-shaped rods 12 are all moved out of the corresponding grooves 8. At this time, the four plug blocks 3 will be released at the same time, and the back shell 2 will fall under the action of gravity. At this time, the back shell 2 is separated from the tablet shell 1, and then the four U-shaped plates 9 can be moved away from each other. As a result, the main board 4 will no longer be fixed by the four U-shaped plates 9 and can be disassembled.

[0066] The embodiments of the present application are described above in conjunction with the accompanying drawings.
