Description

  The present invention relates to an antenna arrangement structure provided indoors in a vehicle such as a passenger car or a commercial vehicle.

  In recent years, in passenger cars and other vehicles, when an occupant with a transmitter approaches the vehicle from outside the vehicle, the door lock is automatically released, or when the occupant with a transmitter approaches the vehicle from outside the vehicle and has a door knob, Some of them are equipped with a vehicle remote control that can be unlocked automatically, or that the engine can be started when a passenger with a transmitter is seated in the seat. It is coming.

When the vehicle remote device as described above is provided, it is necessary to provide the vehicle with an antenna for receiving the signal of the transmitter. For example, as disclosed in Patent Document 1, the vehicle is externally installed in the upper part of the seat back portion. Antenna (receives transmitter signal when a passenger with a transmitter approaches the vehicle from outside the vehicle), or an antenna for the interior of the console box (a passenger with a transmitter sits on the seat) Receive the signal of the transmitter when you are).
In this way, when the antenna for outside and inside the vehicle is provided inside the upper part of the seat back part or inside the console box, it is attached to the frame arranged inside the seat back part or the floor panel inside the console box. A seat is formed, and antennas for the outside and the inside of the vehicle are attached to the mounting seats of the frame and the floor panel.

JP 2000-255381 A

  The in-vehicle antenna that receives the signal of the transmitter when the occupant with the transmitter is seated in the seat makes it possible to start the engine when the occupant with the transmitter is seated in the seat Therefore, it is necessary not to receive the signal of the transmitter when the passenger with the transmitter is outside the vehicle (the reception area of the antenna for the vehicle should not go out of the vehicle) Need to be). Accordingly, it is necessary to arrange the vehicle antenna at an appropriate position in accordance with the size of the vehicle, the arrangement in the vehicle, and the like.

However, when the mounting seat is formed on the floor panel inside the console box and the antenna for the vehicle interior is mounted on the floor panel mounting seat, as described above, according to the size of the vehicle and the arrangement in the vehicle, When an in-vehicle antenna is arranged at an appropriate position, it is necessary to change the position of the floor panel mounting seat by changing the design of the floor panel every time the position of the in-vehicle antenna is changed.
In this case, the floor panel is formed with many necessary components adjacent to the mounting seat, so if the position of the mounting seat is changed, the design change such as the position change of the adjacent required component Need to do. As a result, the design change of the floor panel involves a relatively large number of design steps, which takes time and increases the cost.

  The present invention relates to a vehicle antenna arrangement structure, particularly when an in-vehicle antenna that receives a signal from a transmitter when an occupant with a transmitter is seated on a seat, the size of the vehicle, the arrangement in the vehicle, etc. It is an object of the present invention to make it possible to easily arrange an in-vehicle antenna at an appropriate position in accordance with the above.

[I]
(Constitution)
The first feature of the present invention resides in the following configuration in the vehicle antenna arrangement structure.
A floor board is placed on the floor panel located below the front side of the seat, and a recess or hole is formed on the upper surface of the floor board. The antenna of the vehicle remote device is disposed in the recess or hole of the floor board, and the floor carpet is placed on the upper surface of the floor board.

(Function)
As described in [Background Art], when it is configured to be attached to the antenna on the mounting seat of the floor panel, a number of necessary components other than the mounting seat are formed adjacent to the floor panel. If the position of the seat is changed, the design change of the floor panel involves a relatively large number of design steps.
On the other hand, as in the first feature of the present invention, the floor board placed on the floor panel located below the front side of the seat is generally integrally formed of synthetic resin such as foamed polystyrene. It is relatively simple compared to the floor panel and requires relatively few components. As a result, the degree of freedom for placing antennas on the floorboard is higher than the degree of freedom for placing antennas on the floor panel. Position changes when placing antennas on the floorboard (floorboard design changes) ) Is relatively easier than the position change (floor panel design change) when the antenna is arranged on the floor panel.

According to the first feature of the present invention, a recess or a hole is formed on the top surface of the floorboard, and the antenna is disposed in the recess or hole of the floorboard, so that the antenna is disposed on the top of the floorboard. become.

Therefore, by lifting or removing the floor carpet from the floor board, The antenna can be easily removed from the floor board.
In this case, since the floor carpet is located on the upper side of the antenna, even if the occupant steps on the antenna, the step load on the occupant is reduced by the floor carpet.

(The invention's effect)
According to the first feature of the present invention, in the antenna arrangement structure of a vehicle, particularly when an in-vehicle antenna that receives a signal from the transmitter when an occupant having the transmitter is seated on the seat is disposed, Due to the high degree of freedom of placement and the ability to change the position when placing the antenna (design change of the floorboard) relatively easily, the antenna can be positioned appropriately according to the size of the vehicle and the placement in the vehicle. Can now be easily arranged.

  According to the first feature of the present invention, the antenna is disposed at a position slightly above the floor panel (the lower surface of the floor board) (upper part of the floor board), and when the antenna receives a signal from the transmitter. This makes it difficult to be affected by the floor panel, and the reception sensitivity of the antenna can be increased.

  According to the first feature of the present invention, the antenna can be easily detached from the floor board by lifting or removing the floor carpet from the floor board, so that the maintainability such as the replacement of the antenna can be improved. did it. Even if an occupant steps on the antenna, the step load on the occupant is alleviated by the floor carpet, which is good in terms of antenna protection.
