DETAILED DESCRIPTION

[0023] This specific implementation is a car multimedia player, and its structural diagram is as follows Figure 1-Figure 4 As shown, the player includes a panel 1, a screen 2, a TP3, a light guide bar 4, a lower guard plate 5 and a PCB assembly 6, wherein the screen 2 is a display screen, the TP3 is a touch screen, the panel 1 has a front side and a back side, the panel 1 is made of copper or aluminum with good thermal conductivity, the screen 2 and the TP3 are fixedly connected to the front side of the panel 1 through the light guide bar 4 and the lower guard plate 5, and the PCB assembly 6 is installed on the back side of the panel 1;

[0024] During operation, the heat generated by the various electronic components on the PCB assembly 6 and the heat generated by the screen can be dissipated through the panel 1 therebetween, so that the panel 1 plays the same role as a heat sink. Since the car multimedia player reduces the two parts of the display bracket and the heat sink, the structure of the whole machine is optimized, and the thickness of the whole car multimedia player is reduced accordingly.

[0025] like Figure 1 and Figure 2 As shown: In this embodiment, the screen 2 is located between the front of the panel 1 and TP3, and a receiving groove 101 is opened on the front of the panel 1, and the receiving groove 101 is used to place the screen 2.

[0026] In this way, a receiving groove 101 of the same size as the screen 2 is opened on the front side of the panel 1, and the depth of the receiving groove 101 is consistent with the thickness of the screen 2. The screen 2 can be installed in the receiving groove 101 by using 3M glue, so that it is stably fixed on the panel 1. It is not only convenient to install, but also difficult for the screen 2 to fall out of the receiving groove 101. During operation, the heat generated by various electronic components on the PCB assembly 6 and the heat generated by the screen can be dissipated through the panel 1 between the two, so that the panel 1 plays the same role as a heat sink.

[0027] like Figure 2 As shown: In this embodiment, a plurality of through holes 102 are formed on the receiving groove 101 , and the through holes 102 pass through the front and rear sides of the panel 1 .

[0028] When the panel 1 is arranged in this way for heat dissipation, the plurality of through holes 102 can be in contact with more air, and the heat absorbed by the panel 1 can be better dissipated to the surroundings, thereby accelerating the heat dissipation effect.

[0029] like Figure 1 and Figure 2 As shown: In this embodiment, a plurality of loading buckles 7 are fixedly connected to the back edge of the panel 1 , the number of the loading buckles 7 is twelve, and the panel 1 is loaded onto the vehicle through the loading buckles 7 .

[0030] Such a configuration enables the mounting buckle 7 to be snap-connected with the slot on the vehicle body. The number of the mounting buckles 7 is twelve or other numbers. This ensures that the panel 1 does not need to be screwed when it is mounted on the vehicle, making the operation more convenient, thereby facilitating the installation of the vehicle multimedia player.

[0031] like Figure 3 and Figure 4 As shown: In this embodiment, a plurality of fixing screw holes 8 are provided on the light guide strip 4 , and mounting holes 9 corresponding to the fixing screw holes 8 are provided on the lower guard plate 5 .

[0032] The number of the fixing screw holes 8 can be four or more, which can be set according to needs. The light guide strip 4 can be fixed to the lower guard plate 5 through the fixing screw holes 8 and the mounting holes 9.

[0033] like Figure 3 and Figure 4 As shown: In this embodiment, the lower guard plate 5 is in an L-shaped structure, and a plurality of mounting screw holes 10 are provided on the lower guard plate 5 , through which the lower guard plate 5 is mounted on the vehicle.

[0034] Such a setting can be fixed to the vehicle body through multiple mounting screw holes 10, so that the car multimedia player is firmly fixed to the vehicle body to avoid shaking. The lower guard plate 5 is integrally formed by injection molding, and multiple reinforcing ribs are arranged on it to improve the overall strength.

[0035] like Figure 1 and Figure 2 As shown: In this embodiment, the PCB assembly 6 includes a PCB board 601, a bracket 602 and a reset button 603, and the PCB board 601 and the reset button 603 are fixedly connected to the back side of the panel 1 through the bracket 602.

[0036] When the configuration is in this way, the heat generated by the various electronic components on the PCB assembly 6 and the heat generated by the screen can be dissipated through the panel 1 between the two. The reset button 603 facilitates the operation of the car multimedia player, making it more convenient to use.

[0037] Working principle: by setting the screen 2 and the touch screen TP3 on the front of the panel 1 and the PCB assembly 6 on the back of the panel 1, the panel 1 can play the same role as the display screen bracket. During operation, the heat generated by the various electronic components on the PCB assembly 6 and the heat generated by the screen can be dissipated through the panel 1 between the two, so that the panel 1 plays the same role as the heat sink. Since the car multimedia player reduces the two parts of the display screen bracket and the heat sink, the structure of the whole machine is optimized, and the thickness of the whole car multimedia player is reduced accordingly. At the same time, a plurality of mounting buckles 7 are fixedly connected to the back edge of the panel 1, and a plurality of mounting screw holes 10 are opened on the lower guard plate 5, so as to facilitate the installation of the car multimedia player, which not only saves material costs and labor installation costs, but also can improve the market competitiveness of the product and facilitate the installation and use of the car multimedia player.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
