Electronic equipment with ejection mechanism

Abstract

The invention relates to the technical field of electronic devices, and especially relates to an electronic device having an ejection mechanism. The electronic device comprises a device housing, a connector arranged in the device housing, an ejected component inserted into the connector, and an ejection mechanism. The ejection mechanism comprises an ejection rod and a force application rod. The force application rod is pressed against the ejection rod, and the ejection rod is pressed against the ejected component. The ejection rod comprises: a supporting portion, wherein the supporting portion is pivoted onto the device housing; a stressed component stressed by the force application rod; a first force application portion for applying a force to the ejected component and ejecting the ejected component to a first position; and a second force application portion for applying a force to the ejected component and ejecting the ejected component from the first position to a second position. The distance between the supporting portion and the stressed component is greater than the distance between the supporting portion and the first force application portion, and less then the distance between the supporting portion and the second force application portion.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an electronic equipment with an ejection mechanism. Background technique [0002] In some electronic products (such as set-top boxes), an ejection mechanism is usually used. The ejection mechanism can push out the components inserted in the connector of the electronic product to facilitate the user to remove or replace them in time. The ejection mechanism uses What is the principle of leverage, refer to figure 1 , assuming that the stress points of the ejector mechanism are point A and point B respectively, and the fulcrum is figure 1 Point O in , where point A is in contact with the part of the force exerted by the outside world, and the force is F 1 ′, point B touches the components in the electronic product, and the force is F 2 ’, in addition, the distance from point A to point O is S 1 ′, the distance from point B to point O is S 2 ′, when S 1 '<S 2 ′,...

The ejection mechanism uses What is the principle of leverage, refer to figure 1 , assuming that the stress points of the ejector mechanism are point A and point B respectively, and the fulcrum is figure 1 Point O in , where point A is in contact with the part of the force exerted by the outside world, and the force is F 1 ′, point B touches the components in the electronic product, and the force is F 2 ’, in addition, the distance from point A to point O is S 1 ′, the distance from point B to point O is S 2 ′, when S 1 '2 ′, according to the leverage principle F 1 '×S 1 '=F 2 '×S 2 ', F 1 '>F 2 ’, then the lever mechanism is a stroke-saving mechanism at this time, that is, the part can be ejected by moving a small distance at the force application point, but it is more laborious in the process of applying force; when S 1 '>S 2 ′, according to the principle of leverage, F 1 '2 ’, then the lever mechanism is a labor-saving mechanism at this time, that is, the part can be ejected by applying a small force at the force application point, but the connected part can be ejected only after the force application point moves a large distance, while in the prior art A compromise solution is adopted, that is, S 1 '=S 2 ’, but it will cause the ejection mechanism to eject the connected parts without effort or stroke
