Description

Technical Field

[0001] The invention relates to the technical field of backlight sources, and in particular to an integrated vehicle-mounted central control LED backlight source. Background Art

[0002] The backlight is an LED light source located behind the LCD display. Since the LCD display itself does not emit light, the luminous effect of the backlight will directly affect the display effect of the LCD display. With the development of information technology, more and more vehicles are now equipped with central control displays. Since the display screen must withstand mechanical vibration while the vehicle is driving, general backlight sources cannot be used directly in the vehicle. In order to ensure that the backlight source can be used normally in the vehicle structure, it is generally necessary to integrate all the structural parts of the backlight source and install them in the central control position.

[0003] When the traditional integrated vehicle-mounted central control backlight source is actually installed and used, it generally has two front and rear frames, and then a clamping component is added in the middle to achieve the clamping and fixation of the light guide plate and the light strip. However, this traditional structure cannot dissipate the heat of the backlight source well, and the buffering and shock absorption effect is poor, and the light guide plate cannot be well protected. Even if some heat dissipation devices are added, the heat dissipation efficiency cannot be actively adjusted according to the operating conditions of the vehicle itself, the energy consumption is high, and the overall use effect is not good.

[0018] During this heat dissipation process, in the initial state, if the car is started but not moved, the light strip is working and the light guide plate will still generate heat, then it will not vibrate greatly. At this time, multiple cooling pumps will dissipate heat together, which consumes a lot of energy. If the car moves, it will vibrate, and the pump cylinder will move up and down relative to the heat dissipation rod, and then the piston block inside the pump cylinder will drive the sealing gasket to move up and down in the pump cylinder. Under the action of the one-way air inlet valve and the one-way air outlet valve, the heat generated on the heat conduction plate can be discharged in time. At the same time, under the action of the mounting arm, the trapezoidal rod will be driven downward, and then the air pump switch will be reset, and the corresponding cooling pump will no longer work. In this case, not only the heat dissipation efficiency can be guaranteed, but also the heat dissipation energy consumption can be reduced, which is more economical. BRIEF DESCRIPTION OF THE DRAWINGS

Under the action of the support pad 33, the light guide plate 9 and the bottom of the heat dissipation rod 12 are tightened and positioned.

[0035] The heat-conducting component includes an exhaust pipe 36 fixedly arranged on the side wall of the upper end of the pump cylinder 10, and a one-way air inlet valve 37 is arranged at one end of the exhaust pipe 36 close to the fixed plate 24. The top of the pump cylinder 10 is fixedly connected to a heat sink 39, and a one-way air outlet valve 38 is arranged on the heat sink 39. The heat sink 39 is correspondingly connected to the filter 3, and the heat generated by the light guide plate 9 can be transferred to the top of the fixed plate 24 through the heat dissipation rod 12. Under the action of the one-way air inlet valve 37, hot air can only enter the pump cylinder 10 through the one-way air inlet valve 37 and cannot be discharged from the one-way air inlet valve 37. Under the action of the one-way air outlet valve 38, hot air can be discharged from the pump cylinder 10 through the one-way air outlet valve 38 and cannot enter the pump cylinder 10 from the one-way air outlet valve 38.

[0036] The piston assembly includes an elastic membrane 40 fixedly arranged in the pump cylinder 10, a piston block 35 is slidably arranged in the pump cylinder 10 above the elastic membrane 40, a sealing gasket 34 is fixedly connected to the top of the piston block 35, and a piston column 41 is slidably arranged on the bottom wall of the pump cylinder 10 below the elastic membrane 40. When the piston block 35 moves up and down in the pump cylinder 10, the gas in the pump cylinder 10 can be discharged and sucked in. Under the action of the elastic membrane 40, the lower end area of ​​the pump cylinder 10 can be sealed to prevent the hot air sucked into the pump cylinder 10 from leaking from the lower end of the pump cylinder 10, thereby ensuring that the hot air can be completely discharged when the piston block 35 moves upward.

[0038] The linkage assembly includes a movable groove 19 opened on the side wall of the mounting rod 11, a movable rod 20 is slidably arranged in the movable groove 19, a rebound member 18 is arranged in the movable groove 19, the top of the rebound member 18 is fixedly connected to the movable rod 20, one side of the movable rod 20 is fixedly connected to a trapezoidal rod 22, the trapezoidal rod 22 is arranged corresponding to the air pump switch 17, the trapezoidal rod 22 is fixedly connected to the extension rod 21 away from the mounting rod 11, and the extension rod 21 is arranged corresponding to the mounting arm 13.

[0039] When the pump cylinder 10 vibrates, it can drive the mounting arm 13 to move up and down, and the mounting arm 13 will contact the expansion rod 21 and then drive the trapezoidal rod 22 to move up and down. When the trapezoidal rod 22 moves, it will contact the air pump switch 17, and the process of squeezing the air pump switch 17 can drive the heat pump 14 to start the heat dissipation work. During this process, the greater the vibration amplitude of the mounting plate 2, the greater the amplitude of the corresponding pump cylinder 10 to drive the expansion rod 21 to move up and down through the mounting arm 13, and then the greater the amplitude of the trapezoidal rod 22 to move up and down, and then the number of heat pumps 14 started is also greater, and the heat dissipation effect will be better.

[0040] The heat dissipation component includes a heat extraction pipe 43 arranged at the air inlet end of the heat dissipation pump 14, the end of the heat extraction pipe 43 is fixedly connected to the air extraction nozzle 44, and the air outlet end of the heat dissipation pump 14 is provided with an air guide pipe 15, and the air outlet end of the air guide pipe 15 is correspondingly connected to the filter screen 3; the outer wall of the installation frame 1 is fixedly connected to the installation ear 6, and the installation ear 6 is provided with a positioning hole 7. When actually using it, the operator will match the positioning hole 7 on the installation ear 6 with the hole on the vehicle installation position, and then use the locking bolts to fix the installation frame 1 and the installation plate 2 matched with the installation frame 1 at the position of the vehicle's central control screen.

[0041] When this embodiment is actually installed and used, the operator only needs to place the light guide plate 9 and the light strip 30 at corresponding positions in the installation frame 1, and then snap the installation plate 2 into place with the installation frame 1 to achieve quick assembly. Then, it can be installed in an integrated manner at the position of the vehicle's central control, and the installation efficiency is also higher. At the same time, during use, the device can flexibly adjust the heat dissipation power according to the actual use of the car, reduce energy consumption while ensuring heat dissipation efficiency, and be more economical.

[0042] Example 3, please refer to Figure 1-Figure 8, the actual application scenario of this device is to provide light source for the display screen at the vehicle-mounted central control position. The actual use principle is that the operator only needs to insert the annular rod 4 at the bottom of the mounting plate 2 into the mounting groove 8, and realize rapid installation under the cooperation of the limit head 27 and the limit groove 5. This structure can be installed in an integrated manner to the vehicle-mounted central control position, and the installation is faster and more convenient. At the same time, during the installation and use process, under normal circumstances, when the vehicle is moving, the light strip 30 will work to provide light source for the screen. In this case, vibration will be generated during the movement of the vehicle, and the pump cylinder 10 will move relative to the light guide plate 9. This vibration effect has a certain buffering effect under the action of the elastic member 29, and can better buffer the vibration, effectively protect the light guide plate 9 below, and improve the service life. At the same time, the heat generated on the light guide plate 9 will be transmitted into the internal space of the mounting frame 1 through the heat dissipation rod 12. At this time, under the action of the heat dissipation pump 14, the heat is pumped out through the exhaust The nozzle 44 and the heat extraction pipe 43 are absorbed by the heat dissipation pump 14 and finally sent out through the air duct 15 to achieve heat dissipation. In this heat dissipation process, in the initial state, if the car is started but not moved, the light strip 30 is working and the light guide plate 9 will still generate heat, so it will not vibrate greatly. At this time, multiple heat dissipation pumps 14 will dissipate heat together, which consumes a lot of energy. If the car moves, it will vibrate, so the pump cylinder 10 will move up and down relative to the heat dissipation rod 12, and then the piston block 35 inside the pump cylinder 10 will drive the sealing gasket 34 to move up and down in the pump cylinder 10. Under the action of the one-way air inlet valve 37 and the one-way air outlet valve 38, the heat generated on the heat conduction plate can be discharged in time. At the same time, under the action of the mounting arm 13, the trapezoidal rod 22 will be driven downward, and then the air pump switch 17 will be reset, and the corresponding heat dissipation pump 14 will no longer work. In this case, not only the heat dissipation efficiency can be guaranteed, but also the heat dissipation energy consumption can be reduced, which is more economical.
