Description

Foldable electronic device Technical Field The present application relates to the field of electronic products, and in particular, to a foldable electronic device. Background With the development of technology, various electronic devices have become indispensable products for daily life and production. Among them, foldable electronic devices have been a growing trend due to their larger display area and portability. However, when the current foldable electronic device is subjected to falling impact, the display screen is extruded, so that the display screen fails. Disclosure of Invention The application provides a foldable electronic device, which can reduce or avoid extrusion of a display screen when falling impact is received, so that the reliability of the display screen is improved. The foldable electronic equipment provided by the application comprises a bearing base, a shell and a limiting swing arm. The shell and the bearing base are distributed along the width direction of the foldable electronic equipment, and the limiting swing arm is connected between the shell and the bearing base. It is understood that the housing includes a first housing and a second housing, and the limit swing arm includes a first limit swing arm and a second limit swing arm. The first limiting swing arm is connected between the first shell and the bearing base, and the second limiting swing arm is connected between the second shell and the bearing base. The display screen comprises a first display part, a third display part and a second display part which are sequentially connected. The first display part is fixed on the first shell, the second display part is fixed on the second shell, and the third display part is opposite to the rotating mechanism. When the foldable electronic device is switched between the unfolded state and the folded state, the display screen can be unfolded or folded along with the foldable electronic device. In this process, both the first display portion and the second display portion are fixed, and therefore the first display portion and the second display portion are not bent. The third display portion may bend or unfold as the state of the foldable electronic device changes. When the foldable electronic device is in the unfolded state, the third display portion is bent. At this time, if the bearing base receives an external impact force, the housing may move a long distance in a direction approaching the bearing base, and thus the third display portion is extruded to fail, and finally the entire display screen is disabled. In order to solve the above problems, in the present application, a housing cavity is disposed on a side of the housing facing the bearing base, and a stop groove is concavely disposed on a bottom surface of the housing cavity. The limiting swing arm comprises a limiting rotating part and a limiting sliding part which are fixedly connected along the width direction. The limiting rotating part is rotationally connected with the bearing base, the limiting sliding part stretches into the accommodating cavity, and one side of the limiting sliding part, facing the bottom surface of the accommodating cavity, is provided with a stop protrusion. When the foldable electronic equipment is in a folded state, the stop protrusion extends into the stop groove and can be abutted against the groove surface of the stop groove along the direction that the shell points to the bearing base. The foldable electronic equipment is in a folding state, when the bearing base receives external impact force, the shell can move downwards under the action of the impact force, and when the shell moves to the abutting joint of the stop bulge of the limiting swing arm and the groove surface of the stop groove, the shell can stop moving under the supporting action of the limiting swing arm. That is, the distance of the downward movement of the housing is the gap between the stop protrusion of the stop swing arm and the groove surface of the stop groove, and the gap is very small or even absent, so that the display screen is not extruded. In some embodiments, the foldable electronic device further includes a mounting member and a carrier plate, the mounting member is fixed in the accommodating cavity, and the carrier plate is disposed in the accommodating cavity and shields the mounting member and the limiting sliding portion. The bearing plate slides and rotates and connects the installed part, and the spacing sliding part slides and rotates and connects one side of bearing plate towards the installed part. The mounting may be used to attach a carrier plate or the like. When the foldable electronic device is switched between the unfolded state and the folded state, the bearing plate can rotate and slide relative to the mounting piece. When the foldable electronic equipment is in an unfolding state, the bearing plate covers the accommodating cavity, and the top surface of the bearing plate and the bearing base s
