Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted electronic equipment protection and heat dissipation technology, and in particular to a high-protection vehicle-mounted terminal embedded fixing device. Background Technology

[0002] With the development of intelligent and digital power industry, special power vehicles (such as inspection vehicles, emergency power supply vehicles, and bypass operation vehicles) are increasingly widely used in power grid operation and maintenance, emergency repair, and construction. These vehicles are typically equipped with various intelligent data acquisition and control devices to achieve functions such as data acquisition, status monitoring, remote communication, and local decision-making. As the core data processing and interaction unit, the performance and reliability of the onboard intelligent terminal directly affect the realization of the vehicle's functions and operational safety.

[0003] Currently, such vehicle-mounted terminals typically need to meet stringent environmental and performance requirements, including a wide operating temperature range, high protection level, vibration resistance, and electromagnetic interference resistance. Especially in the humid, dusty, and frequently vibrating environment of a vehicle, the long-term stable operation of the terminal faces two major challenges: first, the terminal's own heat dissipation problem, as it generates a large amount of heat during operation, and poor heat dissipation can easily lead to performance degradation or device damage; second, the problem of moisture and condensation prevention, as the humidity inside a vehicle varies greatly, especially during the rainy season or periods of fluctuating temperatures, which can easily cause condensation inside the terminal, leading to short circuits, corrosion, or decreased insulation.

[0004] Existing vehicle-mounted terminals mostly adopt passive heat dissipation or simple fan heat dissipation designs, with sealing as the main protection method. However, in practical applications, although simple sealing design can prevent dust and moisture, it is not conducive to heat dissipation, especially when the terminal is running under high load. Ordinary air cooling can easily draw humid and dusty external air into the device, which will increase the risk of condensation and contamination. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in the prior art, high-power vehicle terminals have difficulty in meeting both heat dissipation requirements and moisture and condensation prevention requirements in complex vehicle environments, and that traditional sealed or simple air-cooling solutions have problems such as insufficient heat dissipation efficiency, easy introduction of humid and dusty air, and poor adaptability. Therefore, a high-protection vehicle terminal embedded fixing device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-protection vehicle-mounted terminal embedded fixing device includes a vehicle-mounted terminal body. A protective cover is provided on the outside of the vehicle-mounted terminal body. The protective cover includes a support plate, a top plate, a rear plate, a front plate, a side plate, and a bottom plate. The front plate and the side plate are movably hinged to the support plate. The support plate is connected to the bottom plate through a connector. The support plate, top plate, rear plate, front plate, and side plate form an upper chamber. In the initial state, the front plate and the side plate are unfolded outward for air convection heat dissipation. The top plate has a first slot, and the top plate and the rear plate are connected to the first slot to form a sealed upper chamber for isolating external high-humidity air; the top plate and the side plate are respectively provided with a first cooling fan and a second cooling fan.

[0007] In some embodiments, the support plate has a through groove on its edge. The support plate, the rear plate, the connector, and the bottom plate form a lower chamber. The rear plate has an air inlet with a barrier mesh for blocking large impurities. The bottom plate has a filter layer and a water-absorbing layer on the side near the air inlet for blocking fine impurities and absorbing moisture from water vapor. The support plate is connected to the bottom plate by a telescopic member for controlling the vertical height of the support plate.

[0008] In some embodiments, the bottom of the base plate has a first perforation, and the top of the base plate is provided with a scraper and a guide groove outside the filter layer. The top of the scraper is provided with an inclined scraping head, which partially squeezes the water-absorbing layer to clean the water and impurities collected on the water-absorbing layer. The upper surface of the scraper is inclined, and the bottom end of the inclined surface is guided to the guide groove.

[0009] In some embodiments, the telescopic member is used to move the support plate downward, so that the filter layer and the water-absorbing layer move downward corresponding to the first perforation, and the scraper head at the top of the scraper squeezes out the water accumulated on the water-absorbing layer and guides it to the diversion channel for collection.

[0010] In some embodiments, temperature and humidity sensors are respectively provided inside and outside the top plate. When the external humidity is higher than the internal humidity, the front plate and side plate flip and close to connect with the first slot to form a sealed upper chamber. The first cooling fan and the second cooling fan draw outward. After the external gas passes through the air inlet, filter layer and water absorption layer in sequence to remove moisture and dust, it enters the upper chamber through the through slot to dissipate heat from the main body of the vehicle terminal.

[0011] In some embodiments, when the humidity inside the protective cover is higher than the humidity outside, the first and second cooling fans rotate in opposite directions, dry air from the outside is introduced into the upper chamber, and the internal moisture flows downward through the absorbent layer for absorption and then is discharged; the discharged hot air dries the absorbent layer, and the impurities accumulated on the absorbent layer are dried. The support plate moves downward, and the scraper head scrapes away the dried impurities with the help of the outward airflow.

[0012] In some embodiments, the rear panel is provided with an elastic layer, and the elastic layer is provided with a docking sleeve. The docking sleeve corresponds to the plug at the rear end of the vehicle terminal body. The cable is connected to the plug through the docking sleeve. The elastic layer is used to make the cable move with the vehicle terminal body when the vehicle terminal body moves up and down.

[0013] In some embodiments, a hinge groove is provided at the edge of the support plate, and hinge posts are respectively provided at the bottom of the front plate and the side plate, with the hinge posts rotatably connected inside the hinge groove; a torsion spring is provided inside the hinge groove, with one end of the torsion spring fixedly connected to the inside of the hinge groove and the other end of the torsion spring fixedly connected to the hinge post.

[0014] In some embodiments, a limiting baffle is provided on the bottom inner side of the first slot, and three limiting baffles are provided, with the three limiting baffles corresponding to one front plate and two side plates respectively.

[0015] In some embodiments, the connector is an elastic sleeve used to support the up-and-down movement of the support plate to maintain the closure of the lower chamber on three sides.

[0016] Compared with the prior art, the present invention provides a highly protective embedded fixing device for vehicle-mounted terminals, which has the following beneficial effects.

[0017] 1. This invention, by detecting the environmental conditions inside and outside the protective cover, reminds the user to flip and close the front and side panels when the external humidity is high, creating a closed space in the upper chamber to isolate the high-humidity air from the outside and utilize the terminal's own heat for self-drying to prevent condensation; when the humidity threat decreases and the heat dissipation demand increases, the cover can be unfolded to restore the open heat dissipation mode. This solves the technical problem of the contradiction between sealing and heat dissipation in traditional solutions.

[0018] 2. In the closed and moisture-proof mode, the invention draws air in through the air inlet of the lower chamber of the base plate by activating the first and second heat dissipation fans. The air flows through the filter layer and the water absorption layer to remove dust and reduce humidity. Then it enters the upper chamber through the channel, flows through the terminal body to carry away heat and is discharged, forming a clean and dry forced heat dissipation air duct that is isolated from the high humidity environment. This ensures heat dissipation efficiency while avoiding the introduction of humid and dusty air.

[0019] 3. This invention uses a telescopic component to move the support plate and the filter and absorbent layers fixed thereon up and down. A scraper fixed to the base plate squeezes and scrapes the absorbent layer, squeezing out the absorbed water and guiding it into a guide channel for collection and discharge, while simultaneously removing attached impurities. This cleaning of the absorbent layer reduces the frequency of equipment maintenance and ensures the durability and stability of the dehumidification effect.

[0020] 4. In this invention, when the humidity inside the protective cover is detected to be higher than that outside, the fan is reversed to introduce dry air from outside into the upper chamber, and then the internal moisture is blown downwards to the water-absorbing layer for absorption, thereby actively reducing the humidity inside the device and enhancing the reliability of preventing internal condensation.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figure 1-5 A high-protection vehicle-mounted terminal embedded fixing device includes a vehicle-mounted terminal body 1. A protective cover 2 is provided on the outside of the vehicle-mounted terminal body 1. The protective cover 2 includes a support plate 3, a top plate 4, a rear plate 5, a front plate 6, a side plate 7, and a bottom plate 10 located at the bottom of the vehicle-mounted terminal body 1. The top plate 4 is fixedly connected to the rear plate 5. The front plate 6 and the side plate 7 are both movably hinged to the support plate 3. The bottom of the support plate 3 is connected to the bottom plate 10 through a connector 8. A telescopic member 9 is provided at the bottom of the support plate 3. The support plate 3 is connected to the bottom plate 10 through the telescopic member 9. The telescopic member 9 is used to control the vertical height of the support plate 3.

[0037] A transparent glass plate and a transparent flexible layer are provided on the front panel 6. The transparent glass plate corresponds to the display screen of the vehicle terminal body 1, and the transparent flexible layer corresponds to the knob of the vehicle terminal body 1. The knob can be operated from the outside through the transparent flexible layer.

[0038] A through groove 301 is provided at the edge of the support plate 3. The area above the support plate 3 is the upper chamber, and the area below the support plate 3 is the lower chamber. The through groove 301 is used to connect the upper and lower chambers. A first cooling fan 402 is provided on the top of the top plate 4, and a first slot 403 is provided on the top plate 4. A second cooling fan 701 is provided on the side plate 7. A hinge groove 302 is provided at the edge of the support plate 3. A hinge post 702 is provided at the bottom of the front plate 6 and the side plate 7, respectively. The hinge post 702 is rotatably connected inside the hinge groove 302. The connecting piece 8 is an elastic sleeve used to keep the lower chamber closed on three sides when the support plate 3 moves up and down.

[0039] When used in this invention, in the initial state, the front plate 6 and the side plate 7 unfold outward under the rotational cooperation of the hinge column 702 and the hinge groove 302, and can dissipate heat from the vehicle terminal body 1 by air convection and the heat dissipation fins 101 on the top of the vehicle terminal body 1.

[0040] A temperature and humidity sensor is installed on the top plate 4. There are two sets of temperature and humidity sensors, located on the inner and outer sides of the top plate 4, respectively. When the temperature and humidity sensor detects high humidity near the vehicle terminal body 1, an alarm signal is sent to the alarm, reminding the occupants to rotate and flip the front plate 6 and side plate 7 upwards to a vertical position using the hinge column 702 and hinge slot 302. At this time, the front plate 6 and side plate 7 correspond to the first slot 403. The telescopic component 9 drives the vehicle terminal body 1 and the support plate 3 to move upwards, allowing the front plate 6 and side plate 7 to pass through the first slot 403 and continue to move upwards. At this time, the upper chamber is sealed, and the front plate 6 and side plate 7 isolate the upper chamber from the external high humidity environment, reducing the amount of high humidity gas entering the upper chamber. At the same time, the vehicle terminal body 1 uses its own heat to achieve self-drying, ensuring that the surface temperature of the vehicle terminal body 1 is always higher than the dew point temperature of the surrounding air, thus preventing condensation. Heat is generated; at this time, the upper chamber is sealed. As heat is continuously generated in the vehicle terminal body 1, the temperature in the upper chamber will become higher and higher. In order to further improve the heat dissipation efficiency of the vehicle terminal body 1, the first cooling fan 402 and the second cooling fan 701 are started. At this time, the exhaust direction of the first cooling fan 402 and the second cooling fan 701 is facing outward. At this time, the external gas enters the lower chamber through the air inlet 502, and then enters the upper chamber through the through groove 301. When the gas flows through the gap between the front plate 6 and the side plate 7 and the vehicle terminal body 1, it carries the heat dissipated outward by the vehicle terminal body 1. The through groove 301 is a U-shaped groove, which is used to improve the overall heat dissipation efficiency of the vehicle terminal body 1. When the airflow moves upward, it passes through multiple areas on the outside of the vehicle terminal body 1, carries the heat on the outside of the vehicle terminal body 1, and then is discharged outward by the negative pressure of the first cooling fan 402 and the second cooling fan 701.

[0041] As an optional solution, a torsion spring is provided inside the hinge groove 302, one end of the torsion spring is fixedly connected to the inside of the hinge groove 302, and the other end of the torsion spring is fixedly connected to the hinge post 702; a limiting baffle 404 is provided on the inner bottom of the first slot 403, and three limiting baffles 404 are provided, each corresponding to one front plate 6 and two side plates 7 respectively; Figure 12As shown, an extension plate 401 is provided on the outer side of the top plate 4 to improve the air convection space. After the front plate 6 and the two side plates 7 are flipped outward, the inner sides of the front plate 6 and the two side plates 7 are located outside the extension plate 401, forming an air convection channel between the front plate 6 and the two side plates 7. Under the action of the torsion spring, the front plate 6 and the side plates 7 are naturally vertical, corresponding to the first slot 403. The limiting baffle 404 limits the front plate 6 and the side plates 7. When the temperature and humidity sensor detects that the humidity near the vehicle terminal body 1 is high, it reports... An alarm signal is sent to the controller, which controls the telescopic component 9 to move the support plate 3 downward, so that the upper surfaces of the front plate 6 and the side plate 7 are located on the lower surface of the top plate 4. Then, under the action of the torsion spring, the front plate 6 and the side plate 7 continue to flip inward to be vertical and correspond to the position of the first slot 403. In this way, when the external humidity is detected to be high, the support plate 3 is automatically controlled to move downward and the front plate 6 and the side plate 7 correspond to the first slot 403. Then, the telescopic component 9 drives the support plate 3 to move upward, forming a closed upper chamber.

[0042] Optionally, the hinge groove 302 has a limiting function on the bottom of the side plate 7 and the front plate 6. When the side plate 7 and the front plate 6 are flipped inward by the torsion spring, the angle between the side plate 7 and the front plate 6 and the support plate 3 is 90°, maintaining the correspondence between the side plate 7 and the front plate 6 and the first slot 403.

[0043] The rear panel 5 is provided with an elastic layer 501, and the elastic layer 501 is provided with a docking sleeve. The docking sleeve corresponds to the plug at the rear end of the vehicle terminal body 1. The cable is inserted into the upper cavity through the docking sleeve and docks with the plug at the rear end of the vehicle terminal body 1. The elastic layer 501 is used to make the cable move up and down with the vehicle terminal body 1 when the vehicle terminal body 1 moves up and down, so as to prevent the cable from detaching from the plug of the vehicle terminal body 1.

[0044] Please continue to refer to Figures 6 to 10 A filter layer 11 is provided on the side of the base plate 10 near the air inlet 502 to block impurities. A water-absorbing layer 1101 is provided on the side of the filter layer 11 near the air inlet 502. The water-absorbing layer 1101 is used to absorb moisture in water vapor when water vapor passes through, thereby reducing the humidity of the gas transported upward through the channel 301. A barrier mesh is provided on the air inlet 502. The filter pore size of the barrier mesh is larger than that of the filter layer 11 to block larger impurities.

[0045] Furthermore, a first perforation 1002 corresponding to and cooperating with the filter layer 11 and the water-absorbing layer 1101 is provided at the bottom of the base plate 10. A scraper 1003 and a guide groove 1004 are provided at the top of the base plate 10 outside the filter layer 11. The top of the scraper 1003 is provided with an inclined scraping head. The scraping head partially squeezes the water-absorbing layer 1101. The upper surface of the scraper 1003 is a slope, and the bottom end of the slope is guided to the guide groove 1004.

[0046] In the initial state, after the front plate 6 and the side plate 7 remain vertical, the distance between the upper surface of the top plate 4 and the top of the front plate 6 is equal to the distance between the scraper head at the top of the scraper 1003 and the top of the absorbent layer 1101. That is, when the telescopic member 9 moves the support plate 3 downward, the front plate 6 and the side plate 7 move downward along the first slot 403 without separating from the top plate 4. At the same time, when the support plate 3 moves downward, the filter layer 11 and the absorbent layer 1101 move downward corresponding to the first perforation 1002. The scraper head at the top of the scraper 1003 squeezes the water accumulated on the absorbent layer 1101 out of the absorbent layer 1101. Under the guidance of the inclined surface on the scraper 1003, the water flows to the guide channel 1004 for collection.

[0047] In summary, during the process of cooling the vehicle terminal body 1 by drawing gas outward through the first cooling fan 402 and the second cooling fan 701, the support plate 3 is moved up and down by the telescopic component 9 at regular intervals. The downward movement of the support plate 3 scrapes off the water adhering to the water-absorbing layer 1101 and restores good air permeability under the guidance of the scraper 1003. Impurities located on the outside of the water-absorbing layer 1101 are removed from the water-absorbing layer 1101 along with the water when the scraper head scrapes the water-absorbing layer 1101 and flow together to collect in the guide channel 1004. The guide channel 1004 can be set so that the middle is higher than the sides. When the water-absorbing layer 1101 absorbs a lot of water, the water squeezed by the scraper head enters the guide channel 1004 and continues to flow to both sides for collection. The lower outlet of the guide channel 1004 can be connected to the outside of the base plate 10 to guide water and impurities to be collected outward. The impurities accumulated at the lower outlet of the guide channel 1004 are periodically removed.

[0048] Furthermore, a humidity sensor is installed in the lower chamber to detect the humidity of the water-absorbing layer 1101 area. When the humidity sensor detects that the humidity in the area reaches a preset value, the support plate 3 is moved up and down intermittently by the telescopic member 9 to scrape the water off the water-absorbing layer 1101.

[0049] Furthermore, based on the two temperature and humidity sensors installed on the inner and outer sides of the top plate 4, during use, the detection values ​​of the two temperature and humidity sensors are compared. That is, when the humidity detected by the temperature and humidity sensor on the outer side is greater than the humidity in the upper cavity, it indicates that the external humidity is greater than the internal humidity. In this case, to prevent external humidity from entering, the air inlet 502 is used as the air intake end for heat dissipation. When the humidity detected by the temperature and humidity sensor on the outer side is less than the humidity in the upper cavity, it indicates that the external humidity is less than the internal humidity. It is actively determined that the water in the upper or inner cavity has evaporated, causing an increase in the humidity in the upper cavity. In order to reduce the humidity in the upper cavity, the first cooling fan 402 and the second cooling fan 701 rotate in opposite directions, introducing external air into the upper cavity and discharging it outward through the channel 301 and the air inlet 502. Specifically, after the external air enters the upper cavity, the airflow carries the humidity in the upper cavity and the heat generated by the vehicle terminal body 1 and moves downward, blowing the heated humidity in the opposite direction to the filter layer 11 and the water absorption layer 1101, thus reducing the humidity in the upper cavity. When the gas passes through the absorbent layer 1101, it is absorbed by the absorbent layer 1101. At the same time, the heat generated by the vehicle terminal body 1 dries the absorbent layer 1101, and the dried gas with high humidity is discharged outwards through the air inlet 502, making the humidity in the upper and lower chambers gradually decrease, thereby avoiding or reducing the generation of condensation on the vehicle terminal body 1. Meanwhile, as the gas is discharged outwards through the air inlet 502, the telescopic component 9 drives the support plate 3 and the vehicle terminal body 1 to move up and down at regular intervals, and the scraping head and the absorbent... The water layer 1101 is partially pressed and squeezed. When the support plate 3 moves the filter layer 11 and the water absorption layer 1101 downward, the scraper head scrapes and removes the dried impurities on the water absorption layer 1101. At the same time, with the help of the outward airflow from the lower chamber, the efficiency of the separation of impurities on the water absorption layer 1101 from the filter layer 11 is accelerated. In this way, the impurities that have accumulated on the water absorption layer 1101 over a long period of time are cleaned. When the air inlet 502 is used as the air inlet again in the future, the amount of gas entering the lower chamber from the outside airflow is maintained.

[0050] The temperature and humidity sensors located on the inner side include two sensors: one sensor has its sensing probe located in the upper chamber, and the other sensor has its sensing probe located in the lower chamber. The two sensors detect the temperature and humidity values ​​in the upper and lower chambers, respectively.

[0051] When the sensor probe in the lower chamber detects that the humidity in the lower chamber is below the set threshold, it indicates that the high humidity in both the upper and lower chambers has been reduced, eliminating the safety hazard of condensation easily forming in the upper chamber. At this time, the front panel 6 and the side panel 7 remain connected to the first slot 403. The second cooling fan 701 can be activated to draw air outwards, and the first cooling fan 402 on the top of the top panel 4 can be activated to allow airflow to continuously enter the upper chamber through the first cooling fan 402 and then be discharged outwards through the second cooling fan 701. This achieves partial circulation and heat dissipation of airflow in the upper chamber. The first cooling fan 402 and the second cooling fan 701 accelerate the gas flow rate in the upper chamber, thereby accelerating the heat dissipation of the upper chamber and the vehicle terminal body 1. In subsequent use, based on the temperature values ​​detected by the two sets of internal and external temperature and humidity sensors, when the external temperature is lower than or close to the temperature inside the cavity, the support plate 3 and the vehicle terminal body 1 are moved downward by the telescopic component 9, so that the front plate 6 and the side plate 7 are separated from the first slot 403 and unfold outward. Then the telescopic component 9 moves upward and resets, and heat dissipation is achieved by gas convection and heat dissipation fins 101. Based on the temperature and humidity sensor on the inside of the top plate 4, when the temperature above the vehicle terminal body 1 is detected to rise and reach the preset temperature threshold, the first heat dissipation fan 402 is started again to blow towards the heat dissipation fins 101 to enhance the gas convection efficiency at the top of the vehicle terminal body 1 and improve the cooling efficiency of the vehicle terminal body 1.

[0052] like Figure 10 and Figure 11 A mounting base 1005 is fixedly connected to the bottom of the base plate 10. The mounting base 1005 is fixedly connected to the interior of the vehicle body. The mounting base 1005 has space inside for the filter layer 11 and the water absorption layer 1101 to move up and down. Optionally, the mounting base 1005 is fixed to the interior of the car body with 3M double-sided tape.

[0053] As an example, the telescopic component 9 can also be an electromagnet, an adsorption block, and a spring. The electromagnet is located on the base plate 10, and the adsorption block is located at the bottom of the support plate 3. The electromagnet is fixedly connected to the support plate 3 through the spring. When the electromagnet is energized, the magnetic force attracts the support plate 3 close to the base plate 10, causing the support plate 3 and the vehicle terminal body 1 to move downward. When the electromagnet is de-energized, the spring's rebound force causes the support plate 3 to return to its original position.

[0054] Depending on the application requirements, the telescopic component 9 can also be an electric push rod. The fixed end of the electric push rod is set on the base plate 10, and the telescopic end of the electric push rod is fixedly connected to the support plate 3. The electric push rod controls the up and down movement of the support plate 3 and the vehicle terminal body 1, thereby controlling the distance between the base plate 10 and the support plate 3.
