BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring system for a vehicle for eliminating a blind spot around the vehicle and assisting safe driving.

[0002]

2. Description of the Related Art Conventionally, as this kind of vehicle monitoring device,
There were television systems and radio wave utilization systems. On the other hand, as a simple system, the present applicant has applied for a vehicle monitoring device that remotely controls a convex mirror by electric power (Japanese Utility Model Application No. 2-556).
1). This monitoring device transmits an electric power of a rotary solenoid or the like to a horizontally rotating arm 30 as shown in FIG. 4, and the convex mirror 2 attached to the tip of this arm 30 is in a horizontal plane when the rotary solenoid is energized. It rotates to reach a monitoring point, and can monitor a blind spot behind the vehicle. When the convex mirror is not used, the current to the rotary solenoid is cut off, and the convex mirror 2 is returned by the elastic force of a return spring (not shown) and is stored in the storage position.

[0003]

However, in the above-described conventional vehicle monitoring device, since the arm rotates at a large angle of about 140 ° in the horizontal direction, there is no obstacle on the locus of the convex mirror or the arm. However, there was a problem that required a large space. For this reason, when installing the monitoring device on a vehicle, not only does it take time to remove or relocate a vehicle structure that is an obstacle, but also when the vehicle is retracted, the convex mirror appears and disappears in a circular orbit in the horizontal plane, There was a problem of interference with obstacles. Further, in the above-described conventional vehicle monitoring device, there is a problem that when the vehicle accelerates or meanders in a state where the convex mirror is stored in the storage position, the convex mirror often jumps out of the storage position. To solve this problem, it is conceivable to increase the elastic force of the return spring. However, if the elastic force of the return spring is increased, a large torque is required when the rotary solenoid is started, which leads to an increase in the size of the device. There is. On the other hand, if a mechanism for preventing the projection of the convex mirror is added, the structure of the monitoring device becomes complicated, and there is a problem that the frequency of failure increases.

An object of the present invention is to eliminate the need for a large mounting space in a horizontal plane by rotating a convex mirror in a vertical plane, to easily mount the mirror to a vehicle, and to mount the vehicle to the very edge of an obstacle behind the vehicle. It is an object of the present invention to provide a vehicle monitoring device that can be moved backward. Another object of the present invention is to provide a monitoring device for a vehicle in which the convex mirror is housed in the lowermost portion of the main body so that the convex mirror can be prevented from jumping out when the vehicle is running with only a simple locking mechanism.

As shown in FIGS. 1 to 3, the monitoring device includes a main body 1, an output shaft 10 protruding from the main body 1, an arm 3 having a base end fixed to a distal end of the output shaft 10, and a ball joint at a distal end of the arm 3. 23, and the convex mirror 2 attached via the first mirror 23.
Although not shown in this example, this monitoring device is attached to the right rear end of the truck with the right handle. The main body 1 includes a gear case 11, a rotary solenoid 6 housed in the gear case 11, and a gear 8 housed in the gear case 11 and fixed to a solenoid rotating shaft 7 of the rotary solenoid 6.
And

The rotary solenoid 6 is electrically connected directly to a back lamp circuit (not shown) of the truck. The output shaft 10 is rotatably mounted on a gear case 11, and a gear 9 meshed with the gear 8 and housed in the gear case 11 is fixed substantially at the center of the output shaft 10 (FIG. 2).

The disk 17 has a predetermined shape until the lever 22 comes into contact with the upper stopper 21 from the end stopper 20. (FIG. 2B). In this example, the angle θ is rotatable within a range of about 90 °. Although not shown, a router triangular spring or the like which can abut on the lever 22 may be disposed at an appropriate position between the end stopper 20 and the upper stopper 21. A brake piece 19 is pressed against the outer peripheral surface of the disk 17 at a predetermined pressure.

The arm 3 is formed by bending the arm 3 upside down (FIG. 1), and a mirror turning shaft 14 is rotatably inserted into the tip of the arm 3 via a turning bearing 13 (FIG. 1). 3). FIG.

As I mentioned [devised effect described above, according to the present invention, mounted only the body to face the output shaft horizontally in the vehicle, a convex rotary solenoid when not in use the convex mirror becomes inoperative <br / > covered with mirror covers the mirror surface portion of the convex mirror surface mirror is positioned substantially below the output shaft in its own weight, the rotor when using the convex mirror
Due to the driving force of the solenoid, the arm rotates about 90 ° about the output shaft in the vertical plane in the vertical plane and rises until the convex mirror is located almost to the side of the output shaft, and the driver of the vehicle drives the blind spot of the vehicle via the convex mirror. First, the working space of the arm and the convex mirror is reduced, and the monitoring device can be easily mounted on the vehicle, so that the monitoring device of the present invention can be easily spread. Secondly, since the vehicle does not protrude to the rear of the vehicle, the vehicle can be moved backward to the very last obstacle behind the vehicle, which is convenient for use in a narrow place. Third, it is possible to prevent the convex mirror from jumping out and fluttering when the vehicle is running. Fourth, as a secondary effect, the return spring is indispensable in the conventional monitoring device, but the monitoring device according to the present invention does not require the return spring, and can effectively utilize the total torque when the rotary solenoid is operated. In addition, the size of the rotary solenoid as a driving source can be reduced. Furthermore, since the rotary solenoid has a feature that the initial torque is extremely small and the end torque is extremely large, the monitoring device of the present invention has a structure that takes advantage of the above-mentioned features, so that the size and weight of the monitoring device can be further reduced. Can be planned.
