DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme of the present application clear, complete description, and the advantages are more clear and obvious, the following will be further described in detail with the embodiments of the present application combined with the drawings. It should be understood that the specific embodiments described here are part of the embodiments of the present application, not all the embodiments, only to explain the embodiments of the present application, and not for the limitation of the embodiments of the present application, all other embodiments obtained by the person skilled in the art without doing creative work, belong to the scope of protection of the present application.

[0036] Embodiment one, please refer to Figures 1 to 14The application provides a display screen assembly and terminal technical scheme, which comprises a display screen body 1, installation grooves 21 are formed on the two sides of the front face of the display screen body 1, an installation frame 12 is connected to the inner wall of the display screen body 1 through glue dropping, a touch screen 13 is fixedly connected to the inner wall of the installation frame 12, a blast-proof film 11 is fixedly connected to the outer wall of the front face of the touch screen 13, a conductive plate 14 is fixedly connected to the inner wall of the installation frame 12, a neodymium-iron-boron permanent magnet one 15 is fixedly connected to the inside of the conductive plate 14 in a rectangular shape, a neodymium-iron-boron permanent magnet two 16 is fixedly connected to the inside of the touch screen 13 in a rectangular shape, the outer wall of the back face of the neodymium-iron-boron permanent magnet two 16 is connected to the outer wall of the front face of the neodymium-iron-boron permanent magnet one 15 in a same-pole repulsion mode, a center console is arranged in the display screen body 1, the back face of the neodymium-iron-boron permanent magnet one 15 is connected to the electromagnetic coil in the center console in a same-pole repulsion mode, an air inlet hole 2 is formed in the outer wall of the display screen body 1 located at the outer wall of the installation groove 21, an installation hole one 42 is formed in the outer wall of the opposite side of the two installation grooves 21, a pushing structure is arranged in the air inlet hole 2 and comprises an electric telescopic rod 22, and the outer wall of one end of the electric telescopic rod 22 is fixedly connected to the inner wall of the installation groove 21.

[0037] The repulsion force between the neodymium-iron-boron permanent magnet one 15 and the electromagnetic coil in the center console in the display screen body 1 realizes non-contact support, reduces the friction between the conductive plate 14 and the hard structure, thereby prolonging the service life of the conductive plate 14, finally, copper is used as the main material of the conductive plate 14, a small amount of silver and zinc are added to the copper to form an alloy, the oxidation resistance and mechanical strength of the conductive plate 14 can be improved, and high conductivity is maintained, thereby improving the conductive effect of the conductive plate 14.

[0038] In the embodiment two, on the basis of the embodiment one, installation hole twos 32 are formed in the outer walls of the two sides of the installation frame 12, a solution shell 3 is fixedly connected to the inner wall of the installation groove 21, the material of the solution shell 3 is soft, a push plate 44 is fixedly connected to the outer wall of one side of the solution shell 3, an extension frame 41 is fixedly connected to the outer wall of the push plate 44, the outer wall of the extension frame 41 is in movable contact with the inside of the installation groove 21, a discharge pipe 31 is fixedly connected to the outer wall of the other side of the solution shell 3, the outer wall of the discharge pipe 31 is movably inserted into the inside of the installation hole two 32, a shell 4 is fixedly connected to the outer wall of one side of the extension frame 41, and the outer wall of the shell 4 is fixedly connected to the inside of the installation groove 21.

[0039] The quick-drying adhesive is sprayed between the touch screen 13 and the conductive plate 14 through the discharge pipe 31, so that the back of the touch screen 13 is covered with the adhesive, and the overall structural stability of the touch screen 13 is enhanced. When the touch screen 13 is impacted, the quick-drying adhesive can quickly solidify and tightly bond the various parts of the touch screen 13 together, effectively reducing the possibility of breaking and splashing. Even if the touch screen 13 breaks, the fragments will be fixed in place by the quick-drying adhesive and will not scatter everywhere, thereby reducing the risk of secondary injury to surrounding personnel and equipment. The explosion-proof film 11 is pasted on the outer wall of the touch screen 13, forming a second protective barrier. The explosion-proof film 11 has high strength and toughness and can withstand a certain impact force when the touch screen 13 breaks and intercept the fragments. When the touch screen 13 breaks, the explosion-proof film 11 can prevent the fragments from splashing directly out, further protecting the safety of the user. The double protection of the quick-drying adhesive and the explosion-proof film 11 provides all-round protection for the touch screen 13, improving its safety and reliability.

[0040] In Example Three, the inner wall of the mounting groove 21 is fixedly connected with the controller 23, and the inner wall of the mounting groove 21 is fixedly connected with the vibration sensor 24. The output end of the electric telescopic rod 22 is fixedly connected with the piston plate 25, the outer wall of the piston plate 25 is slidably connected with the inside of the shell 4, the push plate 44 is provided with a through hole with two side walls connected, the through hole is slidably connected with the air outlet pipe 43, the outer wall of one end of the air outlet pipe 43 is fixedly connected with the air outlet head 45, the outer wall of the air outlet head 45 is penetratingly connected with the inside of the mounting hole 42, and the outer wall of the air outlet pipe 43 is penetratingly and fixedly connected with the inside of the solution shell 3.

[0041] The temperature of the conductive plate 14 is reduced, which avoids that the high temperature of the conductive plate 14 affects its electrical performance, causes the resistance to increase and the signal to attenuate, and further affects the stable transmission of the electrical signal. The effective heat dissipation measure reduces the temperature of the conductive plate 14, ensures that the conductive plate 14 operates within a normal working temperature range, maintains the stable transmission of the electrical signal, and guarantees that the display screen body 1 can accurately display images and information.

[0042] When the air outlet pipe 43 contacts the quick-drying adhesive inside the solution shell 3, it can absorb the heat inside the quick-drying adhesive. When the airflow passes through the inside of the air outlet pipe 43, it will undergo convective heat exchange with the inner wall of the air outlet pipe 43. Since the temperature of the airflow is usually lower than that of the inner wall of the air outlet pipe 43, the airflow will carry away the heat of the inner wall of the air outlet pipe 43, thereby reducing the overall temperature of the air outlet pipe 43. This process will maintain the heat absorption capacity of the outer wall of the air outlet pipe 43 for the quick-drying adhesive, forming a virtuous cycle of heat absorption and heat dissipation.

[0043] The embodiment four is based on the embodiment three, the outer wall of the shell 4 on one side is provided with a groove 6, the inner part of the groove 6 is fixedly connected with a limiting rod 61, the limiting rod 61 is fixedly connected with a sensing block 62, the outer wall of the electric telescopic rod 22 is provided with a sliding groove 63, and the inner part of the sliding groove 63 is slidably connected with the outer wall of the limiting rod 61.

[0044] When one end of the sliding groove 63 is in contact with the sensing block 62 arranged on the limiting rod 61, the electric telescopic rod 22 pushes the piston plate 25 to contact the push plate 44, the sensing block 62 can quickly sense the contact information and accurately transmit the information to the controller 23, and the controller 23 can immediately issue a control instruction to make the electric telescopic rod 22 return to the original position after receiving the signal, so that the reciprocating movement of the electric telescopic rod 22 is realized, the electric telescopic rod 22 is prevented from continuously pushing the piston plate 25 to move forward to press the push plate 44, and the movement range of the electric telescopic rod 22 is accurately controlled, so that the whole device can move efficiently in a safe and stable state.

[0045] The embodiment five is based on the embodiment three, the piston plate 25 is fixedly connected with the air inlet pipe 5, the inner part of the air inlet pipe 5 is fixedly connected with a fixed plate 52, the inner part of the air inlet pipe 5 is slidably connected with a U-shaped sealing shell 51, the inner part of the U-shaped sealing shell 51 is fixedly connected with a return spring 53, one end of the return spring 53 is fixedly connected with the outer wall of one side of the fixed plate 52, and the outer wall of the U-shaped sealing shell 51 is provided with a strip-shaped hole.

[0046] Through the change of the air pressure in the shell 4, an outward pushing force is generated to push the U-shaped sealing shell 51 into the inner part of the air inlet pipe 5, so that the U-shaped sealing shell 51 is closed, the air in the shell 4 is prevented from flowing out from the air inlet pipe 5 when the piston plate 25 moves, the sealing property of the air inlet pipe 5 is improved, the one-way flow of the gas is ensured, the gas only enters but does not exit, and the stable movement of the heat dissipation system is ensured.

[0047] The embodiment six is based on the embodiment three, the inner part of the air outlet pipe 43 is fixedly connected with a mounting plate 431, the inner part of the mounting plate 431 is rotatably connected with a rotating plate 432, the outer wall of the back surface of the mounting plate 431 is fixedly connected with a limiting plate 433, and the outer wall of the rotating plate 432 is movably contacted with the outer wall of the limiting plate 433.

[0048] The rotation angle of the rotating plate 432 on the mounting plate 431 is limited within a certain acute angle range through the limiting of the limiting plate 433, so that when the piston plate 25 returns, if the gas enters the inner part of the air outlet pipe 43, the rotating plate 432 is pushed to close, the efficiency of the torsional spring driving the rotating plate 432 to close is further improved, and the response speed and accuracy of the airflow control are improved.

[0049] The working principle and use process of the present application are as follows: during work, first, through the neodymium-iron-boron permanent magnet two 16 arranged on the touch screen 13 and the neodymium-iron-boron permanent magnet one 15 arranged on the conductive plate 14, the repulsive force between the neodymium-iron-boron permanent magnet one 15 and the neodymium-iron-boron permanent magnet two 16 is used to generate a certain gap between the touch screen 13 and the conductive plate 14, the gap is filled with air to form physical isolation, which avoids the problem that the micro convex may pierce the insulating layer to cause short circuit when the conductive plate 14 with high surface roughness is directly attached to the touch screen 13, and correspondingly, the air filling can prevent electrical failure even if there is a defect on the surface of the conductive plate 14, which not only solves the short circuit problem, but also provides a basis for subsequent non-contact support, and then the repulsive force between the neodymium-iron-boron permanent magnet one 15 and the electromagnetic coil on the center console inside the display screen body 1 is used to realize non-contact support, which reduces the friction between the conductive plate 14 and the hard structure, thereby prolonging the service life of the conductive plate 14, finally, copper is used as the main material of the conductive plate 14, a small amount of silver and zinc is added to form an alloy, which can improve the oxidation resistance and mechanical strength of the conductive plate 14 while maintaining high conductivity, thereby improving the conductivity effect of the conductive plate 14.

[0050] In hot summer, when the display screen body 1 works, the conductive plate 14 generates high temperature due to large work load of transmitting electrical signals, at this time, the electric telescopic rod 22 is started, the movement of the electric telescopic rod 22 can drive the piston plate 25 to move in the shell 4 and the telescopic frame 41, by moving the piston plate 25 in the shell 4, the pressure of the air in the shell 4 is changed, when the air in the shell 4 is sprayed to the back of the conductive plate 14 through the air outlet head 45 on the air outlet pipe 43, the air boundary layer near the surface of the conductive plate 14 will be destroyed, the air boundary layer is a layer of air close to the surface of the object with slow flow rate, which will hinder the heat transfer from the conductive plate 14 to the surrounding air, after the high-speed airflow breaks through this boundary layer, the heat exchange speed between the conductive plate 14 and the surrounding air is accelerated, the heat generated by the conductive plate 14 is more quickly dissipated into the air, thereby reducing the temperature of the conductive plate 14, avoiding the problem that the high temperature of the conductive plate 14 will affect its electrical properties, leading to increased resistance, signal attenuation, and further affecting the stable transmission of electrical signals, the effective heat dissipation measure reduces the temperature of the conductive plate 14, ensures that the conductive plate 14 operates within the normal working temperature range, maintains the stable transmission of electrical signals, and ensures that the display screen body 1 can accurately display images and information.

[0051] It should be noted that: due to the car air conditioner inside the car, the air temperature inside the car is low, the low temperature air enters the inside of the installation groove 21 through the air inlet hole 2, and finally enters the inside of the shell 4, and then enters the inside of the display screen body 1 from the air outlet head 45 and sprays to the conductive plate 14. There is a large temperature difference between the surface of the conductive plate 14. According to the principle of heat transfer, the greater the temperature difference, the faster the heat transfer speed, so it can more quickly take away the heat generated by the conductive plate 14, effectively reduce its temperature, ensure that the conductive plate 14 works at an appropriate temperature, maintain the stable transmission of the electric signal, and ensure that the display screen body 1 normally displays images and responds to touch operation.

[0052] Because the material of the air outlet pipe 43 has a heat conduction effect, when the air outlet pipe 43 is in contact with the quick-drying glue inside the solution shell 3, it can absorb the heat inside the quick-drying glue. When the airflow passes through the inside of the air outlet pipe 43, it will exchange heat with the inner wall of the air outlet pipe 43. Because the temperature of the airflow is usually lower than the temperature of the inner wall of the air outlet pipe 43, the airflow will take away the heat of the inner wall of the air outlet pipe 43, thereby reducing the overall temperature of the air outlet pipe 43. This process will maintain the heat absorption ability of the outer wall of the air outlet pipe 43 to the quick-drying glue, forming a benign cycle of heat absorption and heat dissipation.

[0053] When one end of the chute 63 is in contact with the sensing block 62 provided on the limiting rod 61, the electric telescopic rod 22 pushes the piston plate 25 to contact the push plate 44, and the sensing block 62 quickly senses this contact information and accurately and accurately transmits the information to the controller 23. After receiving this signal, the controller 23 will immediately issue a control instruction to make the electric telescopic rod 22 return to the original position. Through this signal feedback and control mechanism, the reciprocating motion of the electric telescopic rod 22 is realized, which avoids the electric telescopic rod 22 continuing to push the piston plate 25 to move forward, causing the push plate 44 to be squeezed, and correspondingly accurately controls the movement range of the electric telescopic rod 22, ensuring that the entire device moves efficiently in a safe and stable state.

[0054] When the piston plate 25 drives the air inlet pipe 5 to stop at the starting end inside the shell 4, the U-shaped sealing shell 51 moves out of the air inlet pipe 5 under the action of the reset spring 53, and the air in the mounting groove 21 can smoothly enter the shell 4 from the strip-shaped hole on the U-shaped sealing shell 51. Sufficient air intake can provide sufficient air flow basis for the subsequent heat dissipation process, ensuring that there is continuous and sufficient air flow for heat exchange when the electric telescopic rod 22 pushes the piston plate 25 to change the air pressure in the shell 4 and sprays air from the air outlet head 45 to the heat dissipation part of the conductive plate 14, thereby more effectively taking away heat and improving heat dissipation efficiency. At the same time, the change of air pressure in the shell 4 produces an outward pushing force, which pushes the U-shaped sealing shell 51 into the inside of the air inlet pipe 5, thereby closing the U-shaped sealing shell 51, avoiding the air in the shell 4 from flowing out from the air inlet pipe 5 when the piston plate 25 moves, and accordingly increasing the sealing performance of the air inlet pipe 5, ensuring one-way flow of gas, only in and not out, and guaranteeing stable movement of the heat dissipation system.

[0055] By setting the mounting plate 431, the rotating plate 432 and the limiting plate 433 inside the air outlet pipe 43, and by setting the torsional spring at the rotating connection between the mounting plate 431 and the rotating plate 432, the rotating plate 432 is driven to restore movement by the action force of the torsional spring after losing the action force of the gas, thereby plugging the inlet and outlet of the air outlet pipe 43, avoiding the air in the display screen body 1 from entering the inside of the shell 4 through the air outlet pipe 43 when the piston plate 25 returns, thereby preventing the air in the display screen body 1 from backflowing, reducing ineffective air flow circulation and heat exchange. This one-way air flow circulation ensures the efficiency and continuity of the heat dissipation process, can timely take away the heat generated by the conductive plate 14, maintain the appropriate working temperature inside the display screen body 1, and guarantee normal operation. The limiting of the rotation of the rotating plate 432 by the limiting plate 433 makes the rotation angle of the rotating plate 432 on the mounting plate 431 within a certain acute angle range, so that when the piston plate 25 returns, if gas enters the inside of the air outlet pipe 43, the rotating plate 432 will be closed, further increasing the efficiency of the torsional spring driving the rotating plate 432 to close, and improving the response speed and accuracy of air flow control.

[0056] Through the setting of the vibration sensor 24, when the car exceeds the vibration set by the vibration sensor 24, it proves that the driver has an accident during driving. At this time, the signal detected by the vibration sensor 24 is immediately transmitted to the controller 23. After the controller 23 receives the signal, it controls the movement of the electric telescopic rod 22 to quickly start the emergency response mechanism. Under normal circumstances, the sliding groove 63 on the electric telescopic rod 22 will stop when it moves to the limit rod 61, which is to limit its movement range and ensure the normal operation of the system. However, in the special case of the driver's accident, the electric telescopic rod 22 needs to continue to move to complete some key actions. At this time, since the limit rod 61 is made of a deformable material, when the sliding groove 63 contacts and continues to move forward, the limit rod 61 will deform, allowing the sliding groove 63 to smoothly pass through the limit rod 61, breaking through the conventional movement limit and ensuring the execution of key actions. Through the limit rod 61 made of a deformable material, the complete movement of the electric telescopic rod 22 in an emergency is ensured, thereby ensuring the smooth progress of the emergency process.

[0057] When the piston plate 25 pushed by the electric telescopic rod 22 contacts and continues to move with the push plate 44, it can make the push plate 44 drive the telescopic frame 41 to stretch and apply uniform and continuous pressure to the solution shell 3. At the same time, since the air outlet pipe 43 is made of lightweight aluminum alloy and ceramic coating, it has heat conduction effect while improving the telescopic response speed. After the piston plate 25 contacts and continues to move with the push plate 44, the piston plate 25 pushes the air outlet pipe 43 to compress. Through the compression of the air outlet pipe 43, it will not affect the extrusion of the push plate 44 to the solution shell 3, so that the quick-drying glue inside the solution shell 3 is sprayed through the discharge pipe 31 between the touch screen 13 and the conductive plate 14, making the back of the touch screen 13 covered with glue, enhancing the overall structural stability of the touch screen 13. When the touch screen 13 is hit, the quick-drying glue can quickly solidify and tightly bond each part of the touch screen 13 together, effectively reducing the possibility of breaking and splashing. Even if the touch screen 13 breaks, the fragments will be fixed in place by the quick-drying glue and will not scatter everywhere, thereby reducing the risk of secondary injury to surrounding personnel and equipment. The explosion-proof film 11 is pasted on the outer wall of the touch screen 13, forming a second protective barrier. The explosion-proof film 11 has high strength and toughness and can withstand a certain impact force when the touch screen 13 breaks and intercept the fragments. When the touch screen 13 breaks, the explosion-proof film 11 can prevent the fragments from splashing directly out, further ensuring the safety of the user. The double protection of the quick-drying glue and the explosion-proof film 11 provides all-round protection for the touch screen 13, improving its safety and reliability.

[0058] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
