DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1

[0027] In one embodiment, Figure 1-Figure 5 As shown, a combined dual-screen vehicle-mounted backlight source includes a mounting plate 1, a backlight assembly plate 2, and a backlight body 3. The mounting plate 1 is fixed to the vehicle by bolts 4. Two mounting plate grooves are provided on the upper surface of the mounting plate 1. The inner side walls of the two mounting plate grooves are slidably connected with the backlight assembly plates 2. The side walls of the two backlight assembly plates 2 are embedded with the backlight body 3. The mounting structure, the disassembly structure, and the heat dissipation structure are also included. The mounting structure is arranged in the mounting plate groove for facilitating the installation of the backlight assembly plate 2. The disassembly structure is arranged on the upper surface of the mounting plate 1 for facilitating the disassembly of the backlight assembly plate 2. The heat dissipation structure is arranged on the lower surface of the mounting plate 1 for dissipating the backlight body 3.

[0028] In one embodiment, Figure 3 and Figure 5 As shown, the installation structure includes a block 9, and the inner side walls of the two assembly plate grooves are provided with four block grooves 15 that are opposite to each other. The inner side walls of the block grooves 15 are slidably connected with the block 9, and a damping spring is fixedly connected between the block 9 and the inner side walls of the block grooves 15. The side walls of the two backlight assembly plates 2 are provided with four grooves corresponding to the block 9, and the block 9 is engaged with the grooves of the backlight assembly plate 2. First, the mounting plate 1 is installed in the vehicle by means of bolts 4, and then the two backlight assembly plates 2 are inserted into the two assembly plate grooves of the mounting plate 1 until they abut against the limit frame 8. The limit frame 8 limits the backlight assembly plate 2 to prevent it from touching the fan blade 6. When the backlight assembly plate 2 is inserted into the assembly plate groove, the block 9 is engaged with the groove of the backlight assembly plate 2 through the cooperation of the damping spring, and the installation is completed. The installation operation is quick and convenient.

[0029] In one embodiment, Figure 2 and Figure 5 As shown, the side wall of the block 9 is provided with a chamfer. Since the side wall of the block 9 is provided with a chamfer, the block 9 is engaged with the groove of the backlight assembly plate 2 more smoothly.

[0030] In one embodiment, Figure 5 As shown, the disassembly structure includes a limit block 11, a handle 12, a pull rope 13, and a pull rope cavity 16. Eight limit block grooves 10 are opened on the upper surface of the mounting plate 1. The inner side walls of the eight limit block grooves 10 are slidably connected to the limit block 11. The upper surface of the limit block 11 is fixedly connected with a handle 12, and the lower surface of the limit block 11 is fixedly connected with a pull rope 13. Eight pull rope cavities 16 are opened in the mounting plate 1. The block groove 15 is connected with the limit block groove 10 through the pull rope cavity 16. The pull rope 13 extends through the pull rope cavity 16 to the block groove 15 and is fixedly connected to the block 9. Pull the handle 12, the handle 12 pulls the limit block 11 out of the limit block groove 10 and rotates it ninety degrees. At this time, the limit block 11 pulls the pull rope 13, and the pull rope 13 pulls the card block 9, so that the card block 9 is pulled into the card block groove 15. The card block 9 and the groove of the backlight source assembly board 2 are released, and the backlight source assembly board 2 can be taken out for maintenance. The disassembly operation is quick and convenient.

[0031] In one embodiment, Figure 5 As shown, the inner wall of the rope chamber 16 is rotatably connected with a fixed pulley 14 through a pin, and the rope 13 passes around the fixed pulley 14. The fixed pulley 14 reduces the wear of the rope 13 and can change the direction of the rope 13 force.

[0032] In one embodiment, Figure 3 and Figure 5 As shown, the limit block 11 is a rectangular parallelepiped. Since the limit block 11 is a rectangular parallelepiped, the limit block 11 can be stuck outside the limit block slot 10 after rotating ninety degrees.

[0033] Example 2

[0034] In one embodiment, Figure 2 and Figure 3 As shown, the heat dissipation structure includes a rotating shaft 5, a fan blade 6, and a motor 7. The bottom walls of the two assembly plate grooves are provided with heat dissipation holes. Brackets are arranged in the two heat dissipation holes. The side walls of the brackets are rotatably connected to the rotating shaft 5 through bearings. The part of the rotating shaft 5 located in the assembly plate groove is fixedly connected to a plurality of fan blades 6. The bottom walls of the two assembly plate grooves are provided with ventilation holes. The lower surface of the mounting plate 1 is fixedly connected to two motors 7 through brackets. The output end of the motor 7 is fixedly connected to the rotating shaft 5. The lower surfaces of the two backlight assembly plates 2 are provided with heat dissipation holes. By starting the motor 7, the motor 7 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the fan blades 6 to rotate, so as to cool down the backlight body 3 and prevent the backlight body 3 from being damaged by excessive temperature.

[0035] In one embodiment, Figure 2 and Figure 3 As shown, the inner side wall of the assembly plate groove is fixedly connected to a limit frame 8. The limit frame 8 limits the backlight assembly plate 2 to prevent contact with the fan blades 6.

[0036] The above embodiment discloses a combined dual-screen vehicle-mounted backlight source. First, the mounting plate 1 is installed in the vehicle by means of bolts 4, and then the two backlight assembly plates 2 are inserted into the two assembly plate grooves of the mounting plate 1 until they abut against the limit frame 8. The limit frame 8 limits the backlight assembly plate 2 to prevent it from touching the fan blades 6. When the backlight assembly plate 2 is inserted into the assembly plate groove, the block 9 cooperates with the damping spring to make the block 9 engage with the groove of the backlight assembly plate 2, and the installation is completed. The installation operation is quick and convenient.

[0037] Since the side wall of the clamping block 9 is provided with a chamfer, the clamping connection between the clamping block 9 and the groove of the backlight assembly plate 2 is smoother;

[0038] When the backlight source body 3 needs to be repaired, it is only necessary to pull the handle 12, which will pull the limit block 11 out of the limit block slot 10 and rotate it ninety degrees. Since the limit block 11 is a rectangular parallelepiped, the limit block 11 can be stuck outside the limit block slot 10 after rotating ninety degrees. At this time, the limit block 11 pulls the pull rope 13, and the pull rope 13 pulls the clamping block 9, so that the clamping block 9 is pulled into the clamping block slot 15. The clamping block 9 is released from the groove of the backlight source assembly plate 2, and the backlight source assembly plate 2 can be taken out for maintenance. The disassembly operation is quick and convenient.

[0039] By starting the motor 7, the motor 7 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the fan blades 6 to rotate, so as to cool the backlight source body 3 and prevent the backlight source body 3 from being damaged by excessive temperature.

[0040] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
