Description

Technical Field

[0001] This utility model relates to the field of instrument panel brim technology, and in particular to an instrument panel brim with defogging function. Background Technology

[0002] In modern cars, dashboard visors are mainly used for decoration and protection of the dashboard. Especially in cold seasons or humid environments, the dashboard is prone to fogging, which can blur the driver's vision and affect driving safety. Although there are defogging devices and air vent designs in the existing technology, they are generally combined with the overall internal air circulation of the car for defogging, which is not very specific to the dashboard. Therefore, we urgently need a dashboard visor with defogging function. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a dashboard brim with defogging function, comprising a dashboard and a brim, wherein an instrument cover is fixedly connected to the outside of the dashboard, the brim is fixed to the top of the instrument cover of the dashboard, and the brim is arc-shaped, characterized in that: it further comprises a defogging mechanism;

[0004] The defogging mechanism includes an air duct assembly and a blowing defogging assembly, which are used to deliver air to the dashboard and form an airflow across the dashboard surface.

[0005] As an improvement to the above technical solution, the air duct assembly includes an air inlet pipe, and the inside of the brim is provided with a mounting groove adapted to the air duct assembly. The outer surface of the air inlet pipe is fixed to the inner wall of the mounting groove. One end of the air inlet pipe is connected to the air outlet of the car's air conditioning system, and the other end of the air inlet pipe is connected to a sealing pipe. The end of the sealing pipe away from the air inlet pipe is connected to an equidistantly distributed air outlet pipe. The other end of the air outlet pipe is connected to a guide block. The bottom surface of the guide block is provided with a blow hole that communicates with the air outlet pipe, and the blow hole faces the dashboard.

[0006] As an improvement to the above technical solution, the air outlet duct is L-shaped.

[0007] As an improvement to the above technical solution, the bottom surface of the guide block is an inclined surface, which is used for blowing air and defogging towards the instrument panel through the air vent.

[0008] As an improvement to the above technical solution, the top surface of the guide block is fixedly connected with equally spaced sealing sleeves, and the end of the air outlet pipe away from the sealing pipe is fixed to the inner wall of the top of the sealing sleeve.

[0009] As an improvement to the above technical solution, the blowing and defogging component includes a fan, and the two ends of the brim are provided with vents that extend to the bottom of the brim. A fan is fixedly connected to the inner wall of the bottom end of the vent, and a heat insulation net is fixedly connected to the inner wall of the top end of the vent. A heating wire is provided at the exhaust port of the fan, and the heating wire is located below the heat insulation net for the fan to circulate air.

[0010] The beneficial effects of this utility model are:

[0011] By integrating the air duct system and the defogging system within the dashboard visor, fog on the dashboard surface can be effectively removed, improving driving safety. The connection between the air duct system and the air conditioning vents ensures the system's high efficiency and avoids affecting other air conditioning vents. The inclined guide blocks and L-shaped air ducts ensure that the airflow is evenly distributed on the dashboard surface, enhancing the defogging effect. In addition, the combination of a fan and heating wires can maintain the defogging function even in low temperature or high humidity environments, ensuring a clear dashboard.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0018] Example 1

[0019] Please see Figure 1-4In this embodiment, the dashboard brim 2 adopts an arc-shaped design, closely adhering to the surface of the dashboard 1, and is connected to the automotive air conditioning system through an air duct assembly. One end of the air inlet pipe 6 is connected to the air outlet of the automotive air conditioning system, and the other end is connected to the sealing pipe 5. The outer surface of the air inlet pipe 6 is fixed in the mounting groove 3 inside the brim 2 to ensure the pipe is stable and effectively prevent airflow leakage. The other end of the air inlet pipe 6 is connected to the sealing pipe 5. The end of the sealing pipe 5 away from the air inlet pipe supplies air to the inside of the brim through multiple equally spaced air outlet pipes 4. The air outlet pipes 4 adopt an L-shaped design to facilitate arrangement inside the brim 2. The airflow direction is further adjusted by the guide block 7. The bottom surface of the guide block 7 is designed as an inclined surface to ensure that the air blowing hole 8 faces the dashboard. The defogging system 1 effectively removes fog from the dashboard surface. Fans 11 are installed in the vents 10 at both ends of the brim 2. The fans 11 are connected to heating wires 13 via exhaust vents. The heating wires are located below the heat insulation mesh 12 and form an air circulation system with the fans 11. By circulating air, the fans 11 not only provide warm airflow but also prevent fog condensation caused by excessively low temperatures. In this embodiment, the entire defogging system, through the combination of the fans 11 and heating wires 13, maintains a clear dashboard surface, ensuring the driver can clearly see the information on the instrument panel. The air inlet pipe 6 and outlet pipe 4 in the air duct assembly stabilize and evenly distribute the airflow, preventing localized fog formation and improving defogging efficiency.

[0020] Example 2

[0021] In this embodiment, the connection between the air duct assembly and the air conditioner outlet preferably adopts a branch structure. The air inlet pipe 6 is connected to one of the branches of the multiple air outlets of the air conditioner to achieve uniform airflow distribution and ensure that the other air outlets of the air conditioning system can work normally.

[0022] Example 3:

[0023] In this embodiment, the bottom surface of the guide block 7 is inclined to ensure that the air vent 8 faces the instrument panel, which increases the direct contact area between the air and the instrument panel, making the defogging effect of the airflow more significant. The setting of the fan 11 makes the airflow circulation more efficient, especially in high humidity conditions, it can still maintain a good defogging effect.

[0024] In the above technical solution, the heat insulation net 12 can be made of existing glass fiber heat insulation and breathable net or ceramic fiber heat insulation and breathable net to avoid the heating wire 13 burning the driver during use.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
