Description

Technical Field

[0001] This invention belongs to the field of automotive display technology, specifically relating to an automotive display screen exterior component and an automotive display screen. Background Technology

[0002] Automotive display screen exterior components are decorative and functional structural components designed around the display screen, including bezels, back covers, touch panels, etc. They enhance the interior's texture and technological atmosphere through materials (such as metal and carbon fiber) and processes (such as narrow bezels and integrated shapes), while also serving practical functions such as protecting the screen and integrating interactive buttons or ambient lighting. As the core interactive interface of the intelligent cockpit, the automotive display screen uses technologies such as LCD, OLED, or Mini LED to present vehicle information, navigation, and multimedia content in the form of a central control screen, instrument panel, HUD, etc. Together, they construct a modern automotive digital cockpit that combines aesthetic design with intelligent experience.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figures 1 to 12This invention provides an exterior component for an automotive display screen and a technical solution for the automotive display screen: It includes a lower exterior component body 1 and an upper exterior component body 11. The outer wall of the top of the lower exterior component body 1 is movably connected to the outer wall of the bottom of the upper exterior component body 11. A panel 12 is fixedly connected to the upper part of the inner wall of the upper exterior component body 11. A layered plate 13 is fixedly connected to the inner wall of the lower exterior component body 1. A mounting groove 2 is fixedly connected to the outer wall of the bottom of the lower exterior component body 1. A micro air pump 21 is fixedly connected inside the mounting groove 2. A placement groove is formed on the outer wall of the bottom of the lower exterior component body 1. The placement slot is movably connected to a base plate 14, and the outer wall of the top of the base plate 14 is provided with a heat dissipation mechanism. The heat dissipation mechanism includes a thermally conductive buffer pad 33 and a base plate 31. The outer wall of the bottom of the thermally conductive buffer pad 33 is fixedly connected to the outer wall of the top of the base plate 14, and the outer wall of the top of the thermally conductive buffer pad 33 is fixedly connected to the outer wall of the bottom of the base plate 31. The outer wall of the top of the base plate 31 is in movable contact with a silver silicone block 32, and the outer wall of the top of a plurality of silver silicone blocks 32 is fixedly connected to a heat-conducting plate 3. The outer wall of the top of the heat-conducting plate 3 is in movable contact with the outer wall of the bottom of the layered plate 13.

[0035] Because the heat-conducting plate 3 and the layered plate 13 are tightly bonded, the heat generated by the internal devices of the display screen is quickly absorbed by the heat-conducting plate 3 through the layered plate 13 and evenly diffused to the outer wall through the high thermal conductivity of the heat-conducting plate 3. Subsequently, the heat is transferred to the substrate 31 through the tight bond between the silver silicone block 32 and the substrate 31. The substrate 31 further dissipates heat through its own large-area structure. At the same time, the thermally conductive buffer pad 33 connected to the bottom of the substrate 31 absorbs mechanical vibration and thermal stress through elastic deformation, which not only protects the display screen structure from impact damage, but also maintains the continuous tight contact between the substrate 31 and the silver silicone block 32, ensuring that the heat dissipation link can still operate stably and efficiently in dynamic environments, thereby reducing the heat of the internal devices of the display screen.

[0036] By placing the silver silicone block 32 between the heat-conducting plate 3 and the substrate 31, the relative displacement of the heat-conducting plate 3 due to bumps or collisions is prevented in vibration scenarios such as automobile traffic. The elastic deformation of the silver silicone block 32 absorbs vibration energy, avoiding the surface coating peeling and structural deformation caused by friction between the heat-conducting plate 3 and the substrate 31. Since the outer layer of the silver silicone block 32 is a highly conductive silver layer and the inner layer is a highly thermally conductive silicone layer, it achieves electromagnetic shielding while buffering vibration, and its weight is lighter than that of a metal shield.

[0037] In Embodiment 2, based on Embodiment 1, sealing plates 34 are fixedly connected to both sides of the substrate 31. The outer wall of the bottom of the sealing plate 34 is fixedly connected to the outer wall of the top of the base plate 14. The opposite side of the two sealing plates 34 is in movable contact with both sides of the heat-conducting plate 3. A diversion groove 22 is fixedly connected to the lower part of the inner wall of the lower outer component body 1. An installation hole 27 is opened on the outer wall of one side of the diversion groove 22. The output end of the micro air pump 21 is fixedly connected to the inside of the installation hole 27. The lower part of the outer wall of the other side of the diversion groove 22 is in movable contact with the outer wall of one end of the substrate 31. The upper part of the outer wall of the other side of the diversion groove 22 is in movable contact with the outer wall of one end of the heat-conducting plate 3. An air outlet 24 is opened on the outer wall of the other side of the diversion groove 22 between the heat-conducting plate 3 and the substrate 31.

[0038] When the micro air pump 21 is activated, the movement of the micro air pump 21 blows the gas into the interior of the distribution groove 22, and then sprays it out through the air outlet 24 on the distribution groove 22 to the position between the heat-conducting plate 3 and the substrate 31, thereby increasing the air flow between the heat-conducting plate 3 and the substrate 31, forcibly removing the heat from the contact surface between the heat-conducting plate 3 and the substrate 31, and improving the heat dissipation efficiency.

[0039] In Example 3, based on Example 2, an exhaust groove 23 is fixedly connected to the lower part of the inner wall of the lower outer part body 1. The lower part of one side of the outer wall of the exhaust groove 23 is in movable contact with the outer wall of the other end of the substrate 31. The upper part of one side of the outer wall of the exhaust groove 23 is in movable contact with the outer wall of the other end of the heat-conducting plate 3. A near-air groove 25 is opened on one side of the outer wall of the exhaust groove 23 between the heat-conducting plate 3 and the substrate 31. An exhaust groove 26 is opened on the upper part of one side of the outer wall of the exhaust groove 23. The outer wall of the top of the exhaust groove 23 is tightly fitted to the upper part of the inner wall of the upper outer part body 11.

[0040] Furthermore, by setting the sealing plate 34, the diversion groove 22 and the exhaust groove 23, a sealing structure is formed between the heat conduction plate 3 and the substrate 31, so that the airflow can only enter the interior of the exhaust groove 23 through the near air groove 25 in the direction of flow, and finally be ejected through the exhaust groove 26. The gas ejected from the exhaust groove 26 will blow the dust on the surface of the panel 12 toward one end of the panel 12, thereby reducing the adhesion of dust to the panel 12 and increasing the cleanliness of the panel 12.

[0041] In Example 4, based on Example 3, a fixing plate 2 5 is fixedly connected to the outer wall of the top of the panel 12, and an adhesive plate 51 is movably connected to the outer wall of the top of the fixing plate 2 5.

[0042] When dust moves to the adhesive plate 51 at one end of the panel 12, the dust can be stuck to the adhesive plate 51 due to its stickiness. Through the movable connection between the adhesive plate 51 and the fixing plate 2 5, the owner can manually pull up the adhesive plate 51 to separate it from the fixing plate 2 5 and replace the adhesive plate 51.

[0043] In Example 5, based on Example 1, a fixing groove 41 is fixedly connected to the outer wall of the top of the substrate 31. A through hole is opened on the heat-conducting plate 3, and a slot 4 is fixedly connected inside the through hole. A protruding block 42 is movably inserted into the slot 4. A groove 43 is opened on the outer wall of the top of the protruding block 42. A fixing plate 44 is fixedly connected to the outer wall of the bottom of the protruding block 42. A mounting plate is rotatably connected to the bottom of the fixing plate 44. A push spring 45 is fixedly connected to the outer wall of the bottom of the mounting plate. The outer wall of the fixing plate 44 is movably inserted into the fixing groove 41.

[0044] When the groove 43 on the protruding block 42 is perpendicular to the strip groove on the slot 4, the movement of the protruding block 42 can be stopped. At this time, the fixing plate 44 is fixed inside the fixing groove 41. By fixing the fixing plate 44, the heat conduction plate 3 and the substrate 31 can be fixed together, avoiding the increase in installation time due to the more complex structure, and correspondingly improving the installation efficiency of the heat conduction plate 3.

[0045] By pushing the spring 45 to provide a constant upward elastic force at the bottom of the fixed plate 44, even if the fixed groove 41 or the fixed plate 44 is slightly deformed due to vibration or thermal expansion and contraction, the pushing spring 45 can still ensure that the outer wall of the fixed plate 44 and the inner wall of the fixed groove 41 are always tightly fitted through the deformation compensation gap. At the same time, the elastic buffer of the pushing spring 45 reduces the range of contact pressure fluctuations, preventing the heat conduction plate 3 from warping or the substrate 31 from deforming due to sudden pressure changes.

[0046] The working principle and usage process of this invention are as follows: During operation, firstly, since the heat-conducting plate 3 and the silver silicone block 32 are fixedly connected, when the heat-conducting plate 3 is placed on the substrate 31, the silver silicone block 32 is simultaneously brought into contact with the substrate 31. During the placement of the heat-conducting plate 3, the slot 4 and the fixing groove 41 are aligned, at which point the strip grooves on the slot 4 and the fixing groove 41 are in the same position. Then, the convex block 42 drives the fixing plate 44 to insert into the interior of the fixing groove 41 through the slot 4 and the strip groove on the fixing groove 41. The convex block 42 is then rotated, which in turn drives the fixing plate 44 to rotate. When the groove 43 on the convex block 42 is perpendicular to the strip groove on the slot 4, the movement of the convex block 42 is stopped. At this point, the fixing plate 44 is fixed inside the fixing groove 41. By fixing the fixing plate 44, the heat-conducting plate 3 and the substrate 31 can be fixed together, avoiding the increased installation time due to a more complex structure and correspondingly improving the installation efficiency of the heat-conducting plate 3.

[0047] It should be noted that by aligning the groove 43 with the direction of the fixing plate 44, it is easier to observe the angle of rotation of the fixing plate 44 inside the fixing groove 41.

[0048] Furthermore, the push spring 45 installed at the bottom of the fixed plate 44, due to its elasticity, can push the fixed plate 44 upward, so that the outer wall of the fixed plate 44 is tightly fitted with the upper part of the inner wall of the fixed groove 41. This prevents the fixed plate 44 from moving without being subjected to external force, thereby increasing the stability of the fixed plate 44. The push spring 45 provides a constant upward elastic force at the bottom of the fixed plate 44. Even if the fixed groove 41 or the fixed plate 44 is slightly deformed due to vibration or thermal expansion and contraction, the push spring 45 can still ensure that the outer wall of the fixed plate 44 and the inner wall of the fixed groove 41 are always tightly fitted through deformation compensation gap. At the same time, the elastic buffer of the push spring 45 reduces the range of contact pressure fluctuations, preventing the heat-conducting plate 3 from warping or the substrate 31 from deforming due to sudden pressure changes.

[0049] Since the substrate 31 is fixed on the base plate 14, after the heat-conducting plate 3 and the substrate 31 are fixed together, the base plate 14 can be fixed to the lower outer surface part body 1 with screws, thereby completing the installation of the heat dissipation mechanism on the lower outer surface part body 1. The base plate 14 and the lower outer surface part body 1 are connected by screws. After the heat dissipation mechanism has been used for a long time, the heat dissipation effect will decrease due to aging. Professionals can remove the screw connection between the base plate 14 and the lower outer surface part body 1, and take the heat dissipation mechanism out of the lower outer surface part body 1 by removing the base plate 14. Then, the fixing plate 44 and the fixing groove 41 can be released, and the heat-conducting plate 3 and the silver silicone block 32 can be replaced. This avoids the need to remove the connection between the lower outer surface part body 1 and the mounting groove 2 when replacing the heat dissipation mechanism. By setting the heat dissipation mechanism and the base plate 14 as a whole, the efficiency of replacing the heat dissipation mechanism is increased.

[0050] Because the heat-conducting plate 3 is tightly attached to the layered plate 13, the heat generated by the internal devices of the display screen is quickly absorbed by the heat-conducting plate 3 through the layered plate 13, and evenly diffused to the outer wall through the high thermal conductivity of the heat-conducting plate 3. Subsequently, the heat is transferred to the substrate 31 through the tight attachment of the silver silicone block 32 to the substrate 31. The substrate 31 further dissipates heat through its own large-area structure. At the same time, the thermally conductive buffer pad 33 connected to the bottom of the substrate 31 absorbs mechanical vibration and thermal stress through elastic deformation, which not only protects the display screen structure from impact damage, but also maintains the continuous tight contact between the substrate 31 and the silver silicone block 32, ensuring that the heat dissipation link can still operate stably and efficiently in dynamic environments, thereby reducing the heat of the internal devices of the display screen.

[0051] By placing the silver silicone block 32 between the heat-conducting plate 3 and the substrate 31, the relative displacement of the heat-conducting plate 3 due to bumps or collisions is prevented in vibration scenarios such as automobile traffic. The elastic deformation of the silver silicone block 32 absorbs vibration energy, avoiding the surface coating peeling and structural deformation caused by friction between the heat-conducting plate 3 and the substrate 31. Since the outer layer of the silver silicone block 32 is a highly conductive silver layer and the inner layer is a highly thermally conductive silicone layer, it achieves electromagnetic shielding while buffering vibration, and its weight is lighter than that of a metal shield.

[0052] When the micro air pump 21 is activated, the movement of the micro air pump 21 blows the gas into the interior of the distribution groove 22, and then sprays it out through the air outlet 24 on the distribution groove 22 to the position between the heat-conducting plate 3 and the substrate 31, thereby increasing the air flow between the heat-conducting plate 3 and the substrate 31, forcibly removing the heat from the contact surface between the heat-conducting plate 3 and the substrate 31, and improving the heat dissipation efficiency.

[0053] Furthermore, by setting the sealing plate 34, the diversion groove 22 and the exhaust groove 23, a sealing structure is formed between the heat conduction plate 3 and the substrate 31, so that the airflow can only enter the interior of the exhaust groove 23 through the near air groove 25 in the direction of flow, and finally be ejected through the exhaust groove 26. The gas ejected from the exhaust groove 26 will blow the dust on the surface of the panel 12 toward one end of the panel 12, thereby reducing the adhesion of dust to the panel 12 and increasing the cleanliness of the panel 12.

[0054] It should be noted that a sealing gasket is provided on the contact surface between the air outlet groove 26 and the upper exterior part body 11.

[0055] When dust moves to the adhesive plate 51 at one end of the panel 12, the dust can be stuck to the adhesive plate 51 due to its stickiness. Through the movable connection between the adhesive plate 51 and the fixing plate 2 5, the owner can manually pull up the adhesive plate 51 to separate it from the fixing plate 2 5 and replace the adhesive plate 51.
