Problems solved by technology

That is, the covering portion has a cylindrical shape, and after forging and forming the block material to some extent into a substantially cylindrical shape close to the covering portion, the outer member is formed by cutting inside the covering portion to near the head, thereby increasing the Processing man-hours and processing costs, and also increases the number of chips to be discarded, which does not save resources and has room for improvement

Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Such as figure 1 As shown, the actuator 20 of this embodiment is used in a hood upturning device (hereinafter, referred to as “upturning device” as appropriate) U as a safety device for automobiles, and the actuator 20 of this embodiment is provided in a vehicle V On the hinge mechanism 9 on the rear end 7c side of the cover panel 7 in the middle.

[0032] A sensor is provided on the front bumper (not shown) of the vehicle V, which can detect or predict a collision with a pedestrian. When a control circuit (not shown) configured to input a signal from the sensor detects a collision between the vehicle V and a pedestrian based on the signal from the sensor, the gas generator 40 of the actuator 20 (see figure 2 with Figure 4 The explosive (not shown) in) is ignited to generate operating gas G, thereby operating the actuator 20, and operating the upturning device U to raise t...

Abstract

The present invention relates to an actuator. The actuator comprises an inner member, which comprises a housing with a cylindrical shape, wherein the housing is used to hold a gas generator, the gas generator is configured to generate an operating gas during operation, and the end portion of the housing is opened so that the operating gas generated by the gas generator can be discharged from the end; and an outer member, which comprises a head portion configured to cover the opening of the housing; and a cover portion with a cylindrical shape, wherein the cover portion extends from the outer peripheral edge of the head portion so as to cover the outer peripheral surface side of the housing, and the outer member that causes an operating gas generated by the gas generator to flow to the inner peripheral surface side of the cover portion on the back surface side of the head portion moves forward away from the inner member. The head portion and the cover portion of the outer member are independent of each other, and the outer member is formed by coupling a corresponding coupling portion of the head portion and a corresponding coupling portion of the cover portion to each other.

Description

Technical field [0001] The present invention relates to an actuator operated by operating gas generated by a gas generator, and, for example, to an actuator suitable for use in an automobile safety device installed on a vehicle. The automobile safety device is, for example, receiving pedestrians ( When the object to be protected), the operation is to lift the cover upturning device of the cover panel. Background technique [0002] In the related art, this type of actuator is used in a cover upturning device configured to lift the cover panel, and this type of actuator includes: an internal member provided with a gas generator, and the gas is generated The device is configured to generate operating gas during operation; and an external member that covers the internal member and moves forward by the operating gas generated by the gas generator to lift the cover panel (see, for example, JP-A-2015-123868 and JP- A-2017-180668). [0003] The internal component includes a cylindrical h...
