DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4As shown, a mainboard of a functional mobile phone based on the M106C technology comprises: a mainboard body 1, a plurality of mounting feet 2 are arranged on the lower side of the mainboard body 1; a buffer mechanism 3, the buffer mechanism 3 for buffering and shock reduction between the mainboard body 1 and the plurality of mounting feet 2 is arranged on one side of the mainboard body 1; a reset mechanism 4, the reset mechanism 4 for pushing and resetting after the buffer mechanism 3 is buffered and pressed down is arranged in the buffer mechanism 3; wherein the reset mechanism 4 comprises a reverse thrust component 401 arranged in the buffer mechanism 3, a limiting component 402 is arranged on one side of the reverse thrust component 401, when the mobile phone falls down or other accidents occur during use, the mainboard body 1 and the chip installed on the upper side are impacted, at this time the impact force is transmitted to the buffer mechanism 3 for buffering, and the buffer mechanism 3 transmits the impact force to the reset mechanism 4 through the flow of liquid for buffering It absorbs and performs secondary buffering. When the absorption is completed, the reset mechanism 4 pushes back the liquid to reset and push back the buffer mechanism 3, so that buffering and shock absorption can be performed in subsequent situations. The flow of liquid has a damping effect to reduce elastic oscillation and prevent secondary damage to the main board body 1. It occupies a small space and height. The liquid storage tank 301 and the compression chamber 305 contain a pressure transmission medium of liquid with low viscosity. The surface of the mounting foot 2 has screw holes that can be connected to the main board chassis. For the staff in this technical field, the main board body 1 is the prior art and will not be further elaborated here. The device forms a shock-absorbing frame while ensuring the shock-absorbing and buffering effect. It has a small size. At the same time, through a large number of lateral pressure transmissions arranged on the side, the overall height is greatly reduced compared to the vertical spring buffer.

[0024] like Figure 2 and Figure 3As shown, the buffer mechanism 3 is provided with two groups, each group of the buffer mechanism 3 includes a liquid storage tank 301 fixedly connected to the side end of the main body 1, the side end of the liquid storage tank 301 is fixedly connected to a connecting piece 306, the side end of the connecting piece 306 is fixedly connected to a compression chamber 305, the liquid storage tank 301 and the compression chamber 305 are fixedly connected to a liquid through pipe 304 at the adjacent ends, the liquid storage tank 301 and the inner wall of the compression chamber 305 are connected to each other through the liquid through pipe 304, the inner wall of the compression chamber 305 is slidably connected to two liquid pushing rods 302, and the two liquid pushing rods 302 The two hinge plates 303 are movably hinged at the far ends, and the two hinge plates 303 are movably hinged to the two mounting feet 2 respectively. When the main board body 1 falls under the impact, the main board body 1 presses down the liquid storage tank 301 and the connecting piece 306, and the connecting piece 306 pushes the compression chamber 305 down, and the push rod 302 enters the compression chamber 305. At the same time, the hinge plate 303 is elastically deformed, and the push rod 302 is pushed into the compression chamber 305 again. The push rod 302 pushes the liquid in the compression chamber 305 into the liquid pipe 304 and the liquid storage tank 3 01, damping is performed through liquid circulation, absorbing part of the impact force while transmitting the remaining impact to the reset mechanism 4. The lower end of the edge of the liquid storage tank 301 has an air pressure balance hole to prevent the reset mechanism 4 from being difficult to push due to air pressure when moving in the liquid storage tank 301. The inner wall of the compression chamber 305 has an upward inclination in an inverted "V" shape. The two push rods 302 are relatively close to the inner wall of the compression chamber 305. The slightly inclined arc of the compression chamber 305 can make the push rod 302 enter the compression chamber 305 more quickly, increasing the impact In order to transmit the impact force that pushes the liquid to move, a plurality of spoilers 307 are fixedly connected to the inner wall of the liquid pipe 304. The plurality of spoilers 307 are installed obliquely in the liquid pipe 304. The circulating liquid can be guided by the spoilers 307. When the liquid is input under pressure, it is less affected by the inclination angle and can transmit the impact normally. When the reset mechanism 4 reverses and resets, the flow of water is blocked to play a damping role, consume the smooth reverse push elastic force, prevent sudden reverse reset, and generate oscillation to cause secondary damage to the main board body 1.

[0025] like Figure 4As shown, the reverse thrust assembly 401 is provided with multiple groups, and each group of reverse thrust assemblies 401 includes a push block 4011 slidably connected to the inner wall of the liquid storage tank 301, and the side end of the push block 4011 is fixedly connected to a flat tooth plate 4012, and the inner wall of the liquid storage tank 301 is rotatably connected to a gear 4013, and the inner wall of the gear 4013 is fixedly connected to a coil spring 4015, and one end of the coil spring 4015 is fixedly connected to a connecting column 4014, and the lower end of the connecting column 4014 is fixedly connected to the inner wall of the liquid storage tank 301. When the push rod 302 pushes the pressure transmission medium to move, the liquid pushes the two push blocks 4011 away from each other, and the push block 4011 pushes the flat tooth plate 4012 to push the gear 4013 to rotate, which is converted into rotation. The gear 4013 transmits the force to the coil spring 4015 for winding and absorption. When the coil spring 4015 has absorbed the force, the coil spring 4015 relaxes, and the gear 4013 reverses, pushing the two flat teeth 4012 and the push block 4011 closer to each other, pushing the pressure transmission medium back, and when the liquid enters the liquid passage 304, it is blocked by the spoiler 307, which greatly reduces the flow speed. The liquid slowly pushes the two push rods 302 away from each other, and the main board body 1 rises and resets to prevent vibration caused by rapid reset, which causes secondary damage to the mobile phone main board. The limit assembly 402 includes a first limit rod 4021 and a second limit rod 4022 fixedly connected to the inner wall of the liquid storage tank 301. The push block 4011 and the flat tooth piece 4012 are both slidably connected to the surface of the second limiting rod 4022, and the push block 4011 is slidably connected to the first limiting rod 4021. When the push block 4011 and the flat tooth piece 4012 slide, they are prone to tilt, affecting the sealing and the meshing effect of the flat tooth piece 4012. Through the limiting and guiding effect of the first limiting rod 4021 and the second limiting rod 4022, the push block 4011 and the flat tooth piece 4012 will not tilt when sliding, and will be more stable. A plurality of soft rubber sheets 5 are fixedly connected to the lower end of the main board body 1. The plurality of soft rubber sheets 5 are respectively arranged at a plurality of right-angle edges of the main board body 1. The soft rubber sheets 5 can assist the lower side of the main board body 1 Buffering. In the case of a large instantaneous impact, because the device itself is relatively flat, when it is compressed by the impact, the mainboard body 1 may be deformed into an arc shape at the moment of impact, and the four corners are easily hit quickly. The soft rubber sheet 5 can make the mainboard body 1 softly contact with the contact surface to reduce damage. The side end of the mainboard body 1 is fixedly connected to a rubber support pad 6, and the upper end of the rubber support pad 6 is fixedly connected to a rubber positioning rod 7. Through the rubber support pad 6 and the rubber positioning rod 7, when the mainboard body 1 moves up and down under the impact, the connection harness and the plug are broken and damaged. At the same time, the rubber positioning rod 7 can position the harness left and right to prevent it from shaking left and right.

[0026] When the utility model is in use, if the mobile phone falls or other accidents occur during use, the main board body 1 and the chip installed on the upper side are impacted. At this time, the impact force presses down the liquid storage tank 301 and the connecting piece 306, and the connecting piece 306 pushes the compression chamber 305 to descend, and the push rod 302 enters the compression chamber 305. At the same time, the hinge plate 303 is elastically deformed, and the push rod 302 is pushed into the compression chamber 305 again. The push rod 302 pushes the liquid in the compression chamber 305 to enter the liquid pipe 304 and the liquid storage tank 301. The liquid pushes the two push blocks 4011 away from each other. The push block 4011 pushes the flat tooth piece 4012 to push the gear 4013 to rotate, which is converted into a rotational force. The gear 4013 transmits the force to the coil spring 4015 to be wound up for absorption. When the coil spring 4015 absorption is completed, at this time the coil spring 4015 is relaxed, the gear 4013 reverses, pushes the two flat teeth 4012 and the push block 4011 closer to each other, pushes the pressure transmission medium back, and when the liquid enters the liquid passage tube 304, it is blocked by the spoiler 307, which greatly reduces the flow speed, and the liquid slowly pushes the two liquid push rods 302 away from each other, and the main board body 1 rises and resets to prevent oscillation caused by rapid reset and secondary damage to the mobile phone main board. At this time, the buffering and shock absorbing effect of the mobile phone main board is completed. While ensuring the shock absorbing and buffering effect, the device is small in size, and a large amount of lateral pressure transmission is carried out through the device arranged on the side, minus the buffer plate, and compared with the vertical spring buffer, the overall height is greatly reduced.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
