Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted terminal systems, and in particular to a vehicle-mounted terminal system with dual-path redundant power supply. Background Art

[0002] The vehicle terminal is the front-end equipment of the vehicle monitoring and management system, and can also be called the vehicle dispatch monitoring terminal. The dual-channel redundant power supply vehicle terminal device is a highly reliable electronic device used on vehicles. It is mainly composed of a main power supply module, a backup power supply module, a power switching unit and a vehicle terminal body. The vehicle terminal device is powered by the main power supply module, and the backup power supply module is in charging or standby state, ready to respond to the failure of the main power supply module at any time. The dual-channel redundant power supply design greatly improves the reliability of the vehicle terminal device. Even if there is a problem with the main power supply, it can ensure that the device continues to work, reducing equipment downtime caused by power failure.

[0003] In the existing vehicle terminal system, the display screen is a part of the vehicle terminal module. When the vehicle is driving, it mainly plays the role of real-time display of navigation routes and voice calls. Since the display screen is mainly set in the middle of the driving area of ​​the vehicle, and the driver's cup holder is generally installed between the two seats in the cab, when the vehicle encounters sudden braking or other emergency situations during driving, the objects in the vehicle will move forward under the action of inertia, which may easily cause the cup in the cab to fly forward. If the cup cover of the cup is not tightly closed at this time, it is easy to cause the water inside it to fly out and spray onto the surface of the display screen in the vehicle terminal system. Since water is conductive and has strong fluidity, when the vehicle terminal system contacts water, the water will quickly enter the circuit inside the device, causing a short circuit between different circuit nodes. The short circuit will increase the current abnormally, and may instantly burn electronic components such as chips, resistors, capacitors, etc., which will cause the vehicle terminal system to fail to work properly. At this time, if the vehicle happens to be driving fast on the highway, the navigation cannot be used normally due to the damage of the vehicle terminal system, and most vehicles do not have a replaceable display screen, which causes the driver to be unable to use the vehicle terminal device normally.

[0036] In this embodiment, the vehicle-mounted display screen 608 is a part of the vehicle-mounted terminal system, and mainly plays the role of real-time display of vehicle information. In order to improve the real-time power supply of the display screen 608, the vehicle-mounted terminal system adopts a dual-way redundant power supply device body 1 to power the vehicle-mounted terminal system, wherein the dual-way redundant power supply device body 1 can improve the power supply reliability of the vehicle-mounted terminal system. Through the redundant design of the dual-way power supply, even if the main power supply fails, the backup power supply can be put into use immediately to ensure the uninterrupted power supply of the vehicle-mounted equipment and effectively reduce the impact of power supply fluctuations on the vehicle-mounted equipment. When external water stains are sprayed onto the surface of the display screen 608, they will flow downward along the display screen 608 under the action of their own gravity. When they move to the surface of the humidity sensor 5, the humidity sensor 5 detects the flow of external water source and transmits the signal to the controller 3, wherein The humidity sensor 5 measures humidity by utilizing the property that the dielectric constant of the hygroscopic material changes with humidity. When the humidity in the environment changes, the dielectric constant of the hygroscopic material will change, thereby causing the capacitance value of the sensor to change. By measuring the capacitance value of the sensor, the relative humidity of the environment can be determined. The information inside the display screen 608 is transmitted to the vehicle-mounted cloud 4 through the controller 3. The vehicle-mounted cloud 4 is mainly used for data reception and storage. After receiving the data transmitted from the vehicle-mounted terminal, the cloud server stores it in a database. The database adopts a relational database. The vehicle-mounted cloud 4 analyzes and processes the stored data, extracts useful information, and then promptly cuts off the power to the display screen 608 and starts the forward and reverse motors 602 at the same time to drive the shaft 603 to rotate, thereby driving the active gear 604 to rotate. Figure 7 As shown, the cross section of the rotating shaft 603 is T-shaped, and its purpose is to limit the driving gear 604. The driving gear 604 drives the driven gear 606 meshing with it to rotate, and then drives the limiting shaft 605 to rotate, so that the rotating rod 607 rotates, and then the display screen 608 that has been stained with water stains is rotated downward in the counterclockwise direction, so that the other spare display screen 608 corresponding to it is flipped upward. When the display screen 608 that has been stained with water stains rotates downward, it also drives the other driven gear 606 to rotate. The rotation of the two driven gears 606 drives the two first tooth rows 609 to move along the slide groove 7 toward the direction of the humidity sensor 5. Fig. 9As shown, the connection between the first tooth row 609 and the slide groove 7 is T-shaped, the purpose of which is to limit the first tooth row 609 and facilitate its movement. The movement of the two first tooth rows 609 drives the moving plate 610 to move forward, thereby driving the installation rod 611 to move forward, and then driving the cleaning sleeve 615 to move in the direction of the display screen 608 stained with water stains, wherein the cleaning sleeve 615 is made of sponge material, which has strong water absorption and automatic expansion and contraction functions, and is an existing mature technology, and no further explanation is given here. When the cleaning sleeve 615 moves When the cleaning sleeve 615 reaches the outer surface of the display screen 608, the water stains retained on the surface of the display screen 608 can be absorbed. In addition, in order to further improve the absorption effect of the cleaning sleeve 615, when the driving shaft 614 drives the cleaning sleeve 615 to move toward the display screen 608, it also drives the gear ring 616 to move forward along the second gear row 617, so that the gear ring 616 rotates under the action of the second gear row 617, thereby driving the cleaning sleeve 615 to rotate. Through the rotation of the cleaning sleeve 615, the water stains retained on the surface of the display screen 608 are further cleaned. Figure 4 and Figure 5 As shown, the display screen 608 is located at the upper part of the cleaning sleeve 615. Since the display screen 608 has a certain curvature during rotation, and the cleaning sleeve 615 itself has strong elasticity, the display screen 608 will not be affected by the cleaning sleeve 615 absorbing moisture on its surface during rotation. When the display screen 608 without water stains rotates to the surface of the shell 2, the display screen 608 can be connected to the dual redundant power supply device body 1 to be powered. At the same time, the information inside the display screen 608 that has been stained with water stains is transmitted to the inside of the display screen 608 through the function of the vehicle-mounted cloud 4, so that the normal use of the display screen 608 in the vehicle-mounted terminal system can be achieved. Through the function of the switching component 6, not only can the display screen 608 stained with water stains be timely powered off and the water stains on its surface be cleaned to protect it, but also the spare display screen 608 can be automatically switched to the outside of the shell 2 to achieve the normal use of the vehicle-mounted display screen 608, further improving the practicality of the vehicle-mounted terminal system, and solving the problem in the prior art that the vehicle-mounted terminal system is stained with water stains and cannot function normally, resulting in the driver being unable to use the vehicle-mounted terminal normally.

[0037] like Figure 1-Figure 2 , Figure 4 and Figure 10-11As shown, an extrusion assembly 8 for collecting water stains is provided near one edge of the inner bottom surface of the shell 2, and the extrusion assembly 8 includes two cylinders 801 for lifting, and the outer surfaces of the two cylinders 801 are fixedly connected to the inner bottom surface of the shell 2 by screws, and a lifting plate 802 is fixedly installed between the top ends of the two cylinders 801, and a slot 807 is provided near the center of the top of the lifting plate 802, and a slider 806 is slidably connected inside the slot 807, and a water storage tank 803 for placing water stains is fixedly connected to the top of the slider 806, and an extrusion plate 804 for squeezing water is fixedly connected to the outer surface of one side of the water storage tank 803, and a plurality of springs 805 are provided on the outer surface of the other side of the water storage tank 803, and one end of the plurality of springs 805 is fixedly connected to the outer surface of the other side of the water storage tank 803, and the other end of the plurality of springs 805 is fixedly connected to the inner wall of the lifting plate 802.

[0038] In this embodiment, after the cleaning sleeve 615 has finished cleaning the surface of the display screen 608 stained with water stains, the two multi-stage electric telescopic rods 612 are first started to shorten and drive the cleaning sleeve 615 to move away from the display screen 608. When it moves to the top of the extrusion plate 804, the two cylinders 801 are started by the controller 3 to extend and drive the extrusion plate 804 to move upward until the inner wall of the extrusion plate 804 tightly squeezes the cleaning sleeve 615. Then, the two multi-stage electric telescopic rods 612 are continued to be started to shorten and drive the cleaning sleeve 615 to move forward. Fig.11 As shown, since the inner wall of the extrusion plate 804 is in a concave arc shape, when the cleaning sleeve 615 moves, the extrusion plate 804 will be driven to move at the same time under the push of the cleaning sleeve 615, so that the slider 806 moves along the slot 807 in the direction of the multiple springs 805, thereby causing the multiple springs 805 to be squeezed. During the movement, the cleaning sleeve 615 will also rotate under the action of the tooth ring 616 and the second tooth row 617, thereby squeezing out the water stains inside it, and entering the water collection tank 803 along the extrusion plate 804 for collection. When the cleaning sleeve 615 is reset, the two cylinders 801 are started again to shorten them, thereby driving the extrusion plate 804 to move downward. When the extrusion plate 804 is separated from the cleaning sleeve 615, the multiple springs 805 can be extended under the action of their own elastic force, thereby driving the extrusion plate 804 and the water collection tank 803 to reset. By cleaning the water stains inside the cleaning sleeve 615, the water stains are prevented from being retained in the cleaning sleeve 615, reducing the water absorption of the cleaning sleeve 615.

[0039] like Figure 1-Figure 2 , Figure 4-Figure 9 and Fig.12As shown, a protective component 9 is arranged near the other side edge of the inner bottom surface of the outer shell 2, and the protective component 9 includes a mounting frame 901, the bottom of the mounting frame 901 is fixedly connected to the inner bottom surface of the outer shell 2 by screws, a leakage plate 902 is fixedly installed between the relative inner walls of the mounting frame 901, and a compression rod 903 is fixedly installed near the bottom of the relative inner wall of the mounting frame 901, and a plurality of exhaust fans 904 are arranged on the top of the compression rod 903.

[0040] In this embodiment, when the display screen 608 stained with water stains rotates to the inside of the housing 2, in order to prevent the water stains from entering the inside of the display screen 608 and causing short circuit or damage to its internal components, the controller 3 starts multiple exhaust fans 904 to generate airflow, accelerate the flow of surrounding air, and take away the water vapor on the surface of the water stains, thereby accelerating the drying speed of the surface of the display screen 608, preventing the water stains from spreading on the surface of the display screen 608, and reducing the potential damage of the water stains to the internal circuit of the display screen 608. Figure 1 and Figure 2 As shown, the outer surface of the shell 2 is provided with a plurality of circular holes, the purpose of which is to facilitate the circulation of internal and external gases, further speed up the cleaning of the display screen 608 stained with water stains, and effectively prevent small particles of water molecules from entering the interior of the display screen 608 and becoming difficult to remove through the protective component 9. Among them, the controller 3 is electrically connected to the dual-channel redundant power supply device body 1, the vehicle-mounted cloud 4, the humidity sensor 5, the forward and reverse motors 602, the display screen 608, the multi-stage electric telescopic rod 612, the cylinder 801 and the exhaust fan 904.

[0041] The use method and working principle of this device: In order to improve the real-time power supply of the vehicle-mounted display screen 608, the vehicle-mounted terminal system adopts a dual-channel redundant power supply device body 1 to power the vehicle-mounted terminal system. When external water stains are sprayed onto the surface of the display screen 608, they will flow downward along the display screen 608 under the action of their own gravity. When they move to the surface of the humidity sensor 5, the humidity sensor 5 detects the flow of external water sources and transmits a signal to the controller 3. The controller 3 transmits the internal information of the display screen 608 to the vehicle-mounted cloud 4, and at the same time starts the forward and reverse motors 602 to drive the rotating shaft 603 to rotate, thereby driving the driving gear 604 to rotate, and then driving the driven gear 606 meshing with it to rotate, and then driving the limit shaft 605 to rotate, so that the rotating rod 607 rotates, and then the display screen 608 that has been stained with water stains rotates downward in a counterclockwise direction, thereby flipping the other spare display screen 608 corresponding to it upward. When the display screen 608 that has been stained with water stains rotates downward The rotation of the two driven gears 606 drives the two first tooth rows 609 to move along the slide groove 7 toward the direction of the humidity sensor 5. The movement of the two first tooth rows 609 drives the movable plate 610 to move forward, thereby driving the mounting rod 611 to move forward, and then driving the cleaning sleeve 615 to move toward the display screen 608 stained with water stains. The cleaning sleeve 615 is made of sponge material. When the cleaning sleeve 615 moves to the outer surface of the display screen 608, the water stains retained on the surface of the display screen 608 can be absorbed. In order to further improve the absorption effect of the cleaning sleeve 615, when the driving shaft 614 drives the cleaning sleeve 615 to move toward the display screen 608, it also drives the gear ring 616 to move forward along the second tooth row 617, thereby making the gear ring 616 rotate under the action of the second tooth row 617, thereby driving the cleaning sleeve 615 to rotate. Through the rotation of the cleaning sleeve 615, the water stains retained on the surface of the display screen 608 are further cleaned. Figure 4 and Figure 5As shown, the display screen 608 is located on the upper part of the cleaning sleeve 615. Since the display screen 608 has a certain curvature during rotation, and the cleaning sleeve 615 itself has strong elasticity, the display screen 608 will not be affected by the cleaning sleeve 615 absorbing moisture on its surface during rotation. When the display screen 608 without water stains rotates to the surface of the shell 2, the display screen 608 can be connected to the dual-channel redundant power supply device body 1 to supply power to it. At the same time, the information inside the display screen 608 that has been stained by water stains is transmitted to the inside of the display screen 608 through the function of the vehicle-mounted cloud 4, so that the vehicle can realize In the normal use of the display screen 608 in the terminal system, when the cleaning sleeve 615 cleans the surface of the display screen 608 stained with water stains, firstly start the two multi-stage electric telescopic rods 612 to shorten them, and drive the cleaning sleeve 615 to move away from the display screen 608. When it moves to the top of the extrusion plate 804, the two cylinders 801 are started by the controller 3 to extend them, and drive the extrusion plate 804 to move upward until the inner wall of the extrusion plate 804 tightly squeezes the cleaning sleeve 615, and then continue to start the two multi-stage electric telescopic rods 612 to continue shortening them, thereby driving the cleaning sleeve 615 to move forward. Fig.11 As shown, since the inner wall of the squeezing plate 804 is in a concave arc shape, when the cleaning sleeve 615 moves, the squeezing plate 804 is driven to move at the same time under the push of the cleaning sleeve 615, so that the slider 806 moves along the slot 807 in the direction of the multiple springs 805, thereby squeezing the multiple springs 805. During the movement, the cleaning sleeve 615 will also rotate under the action of the gear ring 616 and the second gear row 617, thereby squeezing out the water stains inside it, and entering the water sump 803 along the squeezing plate 804 for collection. When the cleaning sleeve 615 is reset, the two cylinders 801 are started again to shorten them, driving the squeezing plate 804 to move downward. When the squeezing plate 804 is separated from the cleaning sleeve 615, the multiple springs 805 can be extended under the action of their own elastic force, thereby driving the squeezing plate 804 and the water storage tank 803 to reset. When the display screen 608 stained with water stains rotates to the inside of the housing 2, in order to prevent the water stains from entering the inside of the display screen 608 and causing short circuit or damage to its internal components, the multiple exhaust fans 904 are started by the controller 3 to generate airflow, accelerate the flow of surrounding air, and take away the water vapor on the surface of the water stains, thereby accelerating the drying speed of the surface of the display screen 608, preventing the water stains from spreading on the surface of the display screen 608, and reducing the potential damage of the water stains to the internal circuit of the display screen 608. Figure 1 and Figure 2 As shown, the outer surface of the housing 2 is provided with a plurality of circular holes for the purpose of facilitating the flow of internal and external gases.
