Box body with connecting rod type clamshell mechanisms

Abstract

The invention discloses a box body with connecting rod type clamshell mechanisms. The box body with the connecting rod type clamshell mechanisms comprises a box body, a box cover and two connecting rod type clamshell mechanisms; each connecting rod type clamshell mechanism comprises an electric pushing rod assembly, a connecting rod assembly, a sliding assembly and a rotating assembly; each electric pushing rod assembly comprises an electric pushing rod and a fixed hinge shaft; the front end of each fixed hinge shaft is hinged to the right end part of the corresponding electric pushing rod; the rear end part of each fixed hinge shaft is fixed to the box body; each sliding assembly comprises a sliding rod which is mounted on the box cover and a sliding block which is mounted on the slidingrod; each connecting rod assembly comprises a connecting rod, an upper hinge shaft, a lower hinge shaft and a follow-up hinge shaft; a middle lug of each connecting rod is hinged to the left end partof the corresponding electric pushing rod through the corresponding follow-up hinge shaft; the upper end of each connecting rod is hinged to the corresponding sliding block through the corresponding upper hinge shaft; the front end part of each lower hinge shaft is hinged to the lower end of the corresponding connecting rod; the rear end part of each lower hinge shaft is fixed to the box body; thecover opening angle can reach 180 degrees or even larger cover opening angle; and the fixed hinge shafts, the follow-up hinge shafts and a box cover rotating shaft are still not positioned in a straight line, and a dead point does not appear.

Description

technical field [0001] The invention relates to the technical field of mechanical link flip cover, in particular to a box with a link type flip mechanism. Background technique [0002] With the continuous development of the economic level, the traditional manual operation methods have been increasingly replaced by modern and automated mechanical equipment. The current clamshell mechanism mostly adopts the motor direct drive form or the push rod direct push type, but because the motor direct drive type is often realized by directly driving the shaft of the case cover through the motor accelerator and decelerator, when the case cover is heavy and large, its The resistance torque is very large, which requires a high-power motor and a high-torque reducer to drive. Such a high-power motor and high-torque reducer either have a long axial length or a large diameter, resulting in the need to vacate the shaft of the box cover. There is a lot of space to lay out such a large motor an...

The current clamshell mechanism mostly adopts the motor direct drive form or the push rod direct push type, but because the motor direct drive type is often realized by directly driving the shaft of the case cover through the motor accelerator and decelerator, when the case cover is heavy and large, its The resistance torque is very large, which requires a high-power motor and a high-torque reducer to drive. Such a high-power motor and high-torque reducer either have a long axial length or a large diameter, resulting in the need to vacate the shaft of the box cover. There is a lot of space to lay out such a large motor and a large reducer, making the whole mechanism not compact enough, or even impossible to realize, such as figure 1 As shown; although the push rod direct push type has a compact structure, due to the existence of the dead point, the maximum flip angle of the push rod direct push type flip mechanism cannot reach 180°. In fact, it is around 170°. Many push rod direct push types The clamshell mechanism has been unable to continue to move because it is close to the dead point and the resistance rises sharply. figure 2 shown
