Abstract

PROBLEM TO BE SOLVED: To eliminate the need for monitoring by a person during a vehicle test, and at the same time to automatically open the hood of a vehicle by providing a gear-lock part that is gear-locked to the hood of the vehicle, a hood opening and closing means, and a hood opening and closing device that retains the opening and closing means and consists of a freely movable trestle part. SOLUTION: A hood opening and closing device 7 is composed of a gear-lock part 11, an opening and closing means 12, a driving means 13, and a trestle part 14. When a hood is to be opened, a solenoid valve 26 is turned on for opening, and air is sent to an air-driven motor 27 by an air supply pipe 24, thus driving the motor 27 for driving a traction body 16, moving the gear-lock part 11 toward the traction body 16 by hoisting a string-shaped body 15, and at the same time increasing the opening of the hood. When the hood is to be closed, the solenoid valve 26 is turned off, and the drive of the motor 27 is stopped, thus moving the hood in a direction being closed by dead weight.

The structure of the opening / closing means 40 is almost the same as that of the opening / closing means 12 of the first embodiment, except that the winding body 16 and the holding mechanism 17 are not provided. Are fixed, and a piston portion 43 for reciprocating the string-like body 15 in the vertical direction is used.

The piston 43, to which the string 15 is fixed at the lower end, has a substantially cylindrical outer shape, and has a rear end connected to a cylinder 49 (details will be described later).

A shaft support member 44 having a substantially U-shaped vertical section is used to connect the piston 43 and the string-like body 15. The shaft support member 44 includes a bottom 45 and rising portions 46, 46 erected from both ends of the bottom 45.
A through-hole 46 ′ is provided above each rising portion 46. The two through holes 46 ',
The screw portion 47 that is inserted into both of 46 ′ is also inserted through the front end of the piston portion 43, so that the shaft support member 44 can rotate with respect to the piston portion 43. Further, a ring portion 48 is provided on the lower surface of the bottom portion 45 so as to be rotatable with respect to the bottom portion 45. One end of the string 15 is connected to the ring portion 48.

Driving means 4 for driving the opening / closing means 40
1 is almost the same as the driving means 13 of the first embodiment, except that there is no air-driven motor 27 and, instead, a cylinder driven by air supplied by an air supply pipe 24. 49 (for example, an air cylinder).

The substantially cylindrical cylinder 49 is rotatably held by a U-shaped member 52 (details will be described later) provided on the upper surface of a gantry body 50 (details will be described later). . An opening 49 'is formed from the front surface of the cylinder 49 toward the inside, and the piston portion 43 is inserted into the opening 49' so as to be movable in the axial direction. When the air is supplied to the cylinder 49 by the air supply pipe 24, the piston 43 is pulled backward.

The bottom side 53 is pivotally supported by a pivoting means 53 ′ so as to be rotatable with respect to a step 51 provided on the upper surface of the gantry body 50.

Next, a procedure for opening and closing the hood B of the vehicle 5 using the hood opening and closing means 39 having the above configuration will be described. First, the hood B of the vehicle 5 is set in an unlocked state in advance, and after the bonnet opening / closing means 39 is positioned, the locking portion 11 is locked at an appropriate position on the hood B. And
When opening the bonnet B, the solenoid valve 26 (see FIG. 2) is turned on to open the bonnet B, and air is sent to the cylinder 49 by the air supply pipe 24. Then, the cylinder 49 is driven, and the piston 43 is moved to the opening 49 ′ of the cylinder 49.
As a result, the string 15 moves in the direction of the cylinder 49. Due to the movement of the string-like body 15, the locking portion 11 also moves toward the cylinder 49, and with this movement, the opening of the bonnet B increases.

The moving distance of the cord 15 by the piston 43 is determined in advance by the cylinder 49
It can be determined by setting how much 3 is raised. Therefore, the bonnet B is opened by a predetermined opening amount by the cord-like body 15 raised by the determined moving distance.

Conversely, in order to close the bonnet B, all that is required is to turn off the solenoid valve 26 to close the bonnet B and stop driving the cylinder 49. By this operation, the bonnet B moves in the closing direction by its own weight until it becomes a closed state. Note that a similar method can be applied to a vehicle in which a damper is used for the opening / closing mechanism of the hood B by removing the damper in advance.

The operation of the solenoid valve 26 is controlled by the control unit 8.
If it is performed automatically by, for example, it is not necessary for a human to monitor to open and close the hood B.

Note that an electric motor, an electric cylinder, an air-driven motor, or the like may be used instead of the cylinder 49 in the above configuration.

The closing means 4 in an environmental test chamber D ₃ of the vehicle
The configuration of 0 is exactly the same as the opening / closing means 40 of the second embodiment.

Driving means 5 for driving the opening / closing means 40
6 is almost the same as the driving means 41 of the second embodiment, except that the cylinder 49 has a U-shaped member 52.
Is held vertically, and the opening 49 ′ faces downward.

The gantry 57 is provided with two gantry main bodies 5.
8, 58, pillars 59, 59 erected on the two gantry body 58, 58, and a horizontal part 60 to which upper ends of the pillars 59, 59 are connected.

Each of the two gantry body bodies 58 has a substantially rectangular parallelepiped shape, and has two casters 31, 31 and two stoppers 32, 32 on the lower surface. Each caster 31 and stopper 32

Next, a procedure for opening and closing the hood B of the vehicle 5 using the hood opening and closing means 55 having the above configuration will be described. First, the hood B of the vehicle 5 is set in an unlocked state in advance, and after the bonnet opening / closing means 55 is positioned, the locking portion 11 is locked at an appropriate position on the hood B. And
When opening the bonnet B, the solenoid valve 26 (see FIG. 2) is turned on to open the bonnet B, and air is sent to the cylinder 49 by the air supply pipe 24. Then, the cylinder 49 is driven, the piston 43 is pulled up, and accordingly, the cord 15 is also pulled up. The lifting of the cord 15 causes the locking portion 11 to move toward the cylinder 49, and with this movement, the opening of the bonnet B increases.

The moving distance of the cord 15 by the piston 43 is determined in advance by the cylinder 49
It can be determined by setting how much 3 is raised. Therefore, the bonnet B is opened by a predetermined opening amount by the cord-like body 15 raised by the determined moving distance.

On the other hand, in order to close the bonnet B, it is only necessary to turn off the solenoid valve 26 to close the bonnet B and stop driving the cylinder 49. By this operation, the bonnet B moves in the closing direction by its own weight until it becomes a closed state. Note that a similar method can be applied to a vehicle in which a damper is used for the opening / closing mechanism of the hood B by removing the damper in advance.

The operation of the solenoid valve 26 is controlled by the control unit 8.
If it is performed automatically by, for example, it is not necessary for a human to monitor to open and close the hood B.

Note that an electric motor, an electric cylinder, an air-driven motor, or the like may be used instead of the cylinder 44 in the above configuration.
