Abstract
Description
[Technical Field]
[0001] The present invention relates to a fixture post as an auxiliary part for mounting an in-vehicle device and to an installation method thereof. [Background technology]
[0002] In recent years, vehicles have come equipped with a variety of standard features that aid in driving, improving convenience, safety, and comfort.
[0003] However, even though many vehicles have high standards for these functions by manufacturer standards, some vehicles may omit these functions due to the manufacturer's design philosophy, vehicle manufacturing costs, grade development, etc. Furthermore, even if these functions are provided, they may not meet the needs of users.
[0004] Therefore, parts manufacturers and the like have proposed a wide variety of auxiliary parts to compensate for and fulfill the deficiencies in various functions, providing users with options for adding or improving various functions.
[0005] In this context, there are a variety of auxiliary parts that can be fixed to the A-pillar or its interior lining, allowing users to attach in-vehicle devices such as smartphones, speakers, and auxiliary mirrors to the vehicle interior.
[0006] As mentioned above, it is often useful to install auxiliary parts on the A-pillar or its interior lining. However, depending on the vehicle equipment, it may not be possible to install it in an effective location, or even if it can be installed, it may impair the vehicle's original functions such as ventilation, or it may significantly impair the interior design.

[0008] [Patent Document 2] Patent Publication No. 2021-059185 Summary of the Invention [Problem to be solved by the invention]
[0009] Therefore, in this invention, we propose a more rational method than the conventional method of installing auxiliary parts for vehicle-mounted equipment on the A-pillar or its lining, in which a fixture pillar as an auxiliary part is installed using several support points, namely the A-pillar or its lining and the dashboard. [Means for solving the problem]
[0010] The present invention relates to a fixture post as a mounting base for vehicle-mounted equipment and a method for installing the fixture post inside a vehicle, wherein the fixture post is hollow or solid and can have connecting parts such as screws, balls, grooves, holes, and protrusions between both ends for attaching the vehicle-mounted equipment or its retaining parts, and when installing the fixture post inside a vehicle, one end of the fixture post is fixed by attaching, hooking, fitting, etc. to the A-pillar or its interior lining, and the other end is fixed to the dashboard in a similar manner, and the fixture post is installed so as to connect the vehicle A-pillar or its interior lining to the dashboard.
[0011] The fixture post is installed so that it has at least two support points: the A-pillar or its lining and the dashboard, and both ends of the fixture post are shaped so that they can easily come off in a specific direction or be easily broken in a specific direction.The fixture post itself can also be designed to be easily broken as long as it does not impede its original purpose. [Effects of the Invention]
[0012] The fixture post as a mounting base for vehicle-mounted equipment of the present invention is stably installed by fixing it to at least two support points: an A-pillar or any point on its interior lining, and any point on the dashboard. By making both ends of the fixture post or the fixture post itself easily destructible or disassembled, it is possible to minimize interference with movement around the dashboard when the airbag is deployed. Furthermore, by optimizing the shape and installation position of the fixture post for each vehicle, it is possible to install the vehicle-mounted equipment without interfering with the vehicle's original functions such as ventilation or the driver's field of view. Furthermore, by devising the shape and placement of the fixture post, it is possible to harmonize the fixture post with the design of the vehicle interior, thereby achieving a more sophisticated interior space.
