However, such a design is difficult
Specifically, the shearing load varies depending on the position where the pressing load is applied to the large-diameter portion 4a, and furthermore, the pressing load is applied along the The radial direction is different, making it difficult to specify the relationship between the pressing force and the shear load of the weak portion 4e
In addition, the weak portion 4e is designed based on the assumption that the shear load acts uniformly on the weak portion 4e in the circumferential direction, but actually, there is a concern that the push button is inclined when a pressing force is applied to an eccentric position on the large diameter portion 4a. As a result, the load applied to the fragile portion 4e becomes unbalanced (circumferentially unbalanced)

Embodiment
[0059] For example, in the internal protrusion regulations in China and Europe, when the operating device has a protrusion protruding 9.5mm or more from the panel, it is required to reduce the protrusion amount of the protrusion when a static load of approximately 380N acts on the protrusion to 9.5mm or less. in order to make Figures 1 to 13The operating device shown in satisfies this requirement, and it is sufficient to design the beam portions 56 and 56D in the following manner.
[0060] 1) Breaking load Pf of each beam
[0061] In this operating device, since the four beam portions 56, 56, 56, and 56D are equally spaced circumferentially at intervals of 90°, in order for the operating button 20 to move backward by receiving a pressing load of 380N, each It is sufficient to design the beams so that the beams are crushed by receiving a load of 380 / 4=95 (N), that is, so that the crushing load Pf per beam is 95N.
[0062] 2) Shape design of the beam
[0063] When the load ...

Provided is a vehicle press-operation member 10 wherein an amount of protrusion from a panel decreases rapidly when receiving a certain amount of pressing force or more, with which it is easy to design a breakable portion for the rapid decrease, and the rapid decrease is reliable. The press-operation member 10 includes a base member 18 and a member to be operated 20 which protrudes from the base member 18 and receives a pressing operation. The base member 18 has a guide holding portion 30 which guides the member to be operated 20 in a pressing operation direction of the member to be operated 20 and a stopper 50 which, by coming in contact with the member to be operated 20, restricts a rearward movement of the member to be operated 20. The member to be operated 20 has a guided portion 46D which is guided by the guide holding portion 30, and a contact portion 56 which, by coming in contact with the stopper 50, restricts a rearward movement of the member to be operated 20. Either of the stopper 50 or the contact portion 56 breaks by receiving a reaction force from the other when the member to be operated 20 receives pressure with a large, certain amount of force or more, thereby allowing a further slide of the member to be operated 20.
Description
technical field [0001] The present invention relates to a vehicular push operation part, which is a part provided on an instrument panel of a vehicle and subjected to a press operation, and capable of being pressed with a certain amount of press load or a greater press load. The shape is changed so as to reduce the amount of protrusion from the surface of an instrument panel or the like, and the present invention relates to a vehicle operating device including the vehicle push operation member. Background technique [0002] In a vehicle such as an automobile, generally, an operation member for operating an air conditioner, an audio device, etc. is provided on a panel (for example, an instrument panel) facing the inner side of the vehicle interior, and a press operation member subjected to a press operation with a finger or the like exists therein . Most of such push operation members are provided to protrude from the panel surface to the inside of the vehicle interior in su...
