Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIGS. 1-6 , a vehicle-mounted multimedia navigation core board includes an outer casing 1, the top of the outer casing 1 is provided with a bolt hole 2, the bottom of the outer casing 1 is provided with a first air inlet 3, and the inner cavity of the outer casing 1 is fixed with a fixed Frame 4, the bottom of the fixed frame 4 is provided with a second air inlet 14, the bottom of the fixed frame 4 is fixed with a motor 7, the power output shaft of the motor 7 is sleeved with a fan 6, and the top of the fixed frame 4 is fixed with a baffle 5 , the top of the baffle 5 is fixed with a fixed rod 10, the outer edge of the fixed rod 10 is sleeved with a spring 9, the outer edge of the top of the fixed rod 10 is slidably connected with a collar 11, and the top of the shell 1 is provided with a core plate 12 , In the above structure, the setting of the baffle 5 is used to avoid that when the fan 6 breaks down, the fan blade fragments splash and collide with the core board 12, which affects the normal operation of the core board 12. At the same time, the force of the spring 9 is used to make the vehicle The vibration of the core board 12 is reduced during severe operation, so that the equipment cannot be used normally due to excessive vibration, and the practicability of the device is improved.

The top of the core board 12 is provided with a circular hole 13, and the number of the circular holes 13 is two. In the above structure, the circular hole 13 on the top of the core board 12 is used, so that the core board 12 and the collar 11 can cooperate by using the spring 9 The force provided by the device provides a shock absorption effect for the device, which avoids the short service life of the device caused by the poor shock absorption effect, and improves the service life of the device.

The outer edge of the collar 11 is fixedly connected to the inner wall of the circular hole 13, and the bottom of the core board 12 is provided with silicone grease.
