Description

Technical Field

[0001] The present application relates to the field of electromechanical engineering technology, and in particular to an emergency stop button. Background Art

[0002] The emergency stop button (EMO button), also known as the "emergency stop button", is a main control appliance, usually designed as a manually controlled push-type switch, connected in series to the control circuit of the equipment. When the equipment is in a dangerous state, the emergency stop button can be pressed to cut off the connection between the equipment and the power supply and stop the equipment from running, thereby ensuring the safety of the operator and avoiding damage to the equipment.

[0003] Usually, the emergency stop button adopts an integrated design. Touching the small area of ​​the emergency stop button protruding from the outer surface of the equipment can cut off the connection between the equipment and the power supply. In actual production, there may be multiple equipment in the factory workshop. When operating a certain equipment, the staff may accidentally touch the edge of the emergency stop button of other equipment, which may cause the equipment to stop and cause losses.

[0004] In special working environments, the emergency stop button triggering mode is changed to achieve the effect of preventing accidental touches. For example, patent CN218585851U discloses an anti-accidental touch type emergency stop button for mines, which adds restrictions to the emergency stop button and requires a "twist and press" mode to enable the emergency stop function. Although the emergency stop button achieves the function of preventing accidental touches, this type of triggering mode increases the time required to achieve emergency stop.

[0005] Patent CN218101012U discloses an emergency stop button protective cover, which achieves the effect of preventing accidental touch by adding a protective shell on the outside of the emergency stop button. However, since the protective shell and the emergency stop button are often not produced in a supporting manner, the protective shell will not match the emergency stop button. If the protective shell is too large, it cannot play a protective role. If the protective shell is too small, it will affect people from triggering the emergency stop in an emergency, resulting in personal injury and equipment damage.

[0006] The emergency stop buttons mentioned above are also difficult to meet some industry requirements. For example, the Semiconductor Equipment and Materials International (SEMI) requires that the emergency stop button be touched with the base of the palm to implement the emergency stop function.

[0007] Therefore, it is necessary to develop an emergency button that can reduce the probability of equipment downtime caused by accidental touch by personnel while meeting the use requirements of most emergency stop buttons. Utility Model Content

It will be apparent to those skilled in the art that various local modifications to the disclosed embodiments are apparent, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present application. Therefore, the present application is not limited to the embodiments shown, but to the widest scope consistent with the claims.

As the number of sub-buttons increases, the probability of preventing the emergency stop button from being accidentally touched will become closer and closer to 100%.

[0056] The emergency stop button provided in the present application will be described in detail below in conjunction with the embodiments and drawings.

[0057] refer to Figures 2 to 4 The embodiment of the present application provides an emergency stop button, including a main housing 100, a plurality of sub-buttons 200 evenly arranged inside the main housing 100, and a second connector 300 and a third connector 400 for electrically connecting the plurality of sub-buttons 200.

When not being pressed, the cap portion 203a is located outside the sub-housing 201 and the main housing 100. When being pressed, the cap portion 203a moves along the axial direction of the sub-housing 201 toward the bottom end of the sub-housing 201, and simultaneously drives the first rod portion 203b to move toward the bottom end of the sub-housing 201.

[0074] In some embodiments, the cap portion 203a is shaped as one-eighth of a sphere, so that the cap portions 203a of the plurality of sub-buttons 200 form a hemispherical button, which is convenient for operators to press with the base of their palms, meeting ergonomic requirements.

When the number of the sub-buttons is four, the probability of preventing accidental touch of the emergency stop button reaches 93.33%.

[0146] In addition, the emergency stop button is a hemispherical button composed of the caps of multiple sub-buttons, which is ergonomically designed and can be directly pressed with the base of the palm, meeting the principle of the International Organization for Semiconductor Equipment and Materials that the base of the palm should touch the emergency stop button.
