Abstract

The embodiment of the application relates to the technical field of folding terminals, and provides a supporting device and electronic equipment. The supporting device comprises a first shell, a second shell, a third shell, a first folding mechanism, a second folding mechanism and a locking mechanism. The first housing and the second housing can be relatively unfolded or relatively folded by a first folding mechanism. The second housing and the third housing can be relatively unfolded or relatively folded by a second folding mechanism. When the supporting device is in a fully folded state, the third shell, the first shell and the second shell are sequentially stacked. The locking mechanism is arranged in the second folding mechanism. The locking mechanism locks the second folding mechanism when the first housing and the second housing are in the unfolded state, so as to prevent the second housing and the third housing from being folded relatively by the second folding mechanism. When the first shell and the second shell are in a completely folded state, the locking mechanism releases the locking of the second folding mechanism, and the second shell and the third shell can be relatively unfolded or relatively folded through the second folding mechanism.

Description

Supporting device and electronic equipment Technical Field The application relates to the technical field of folding terminals, in particular to a supporting device and electronic equipment. Background The existing electronic equipment with multi-fold structures such as three folds is complex in folding mechanism and various in folding mode. If the user adopts an improper folding sequence, the folding mechanism and/or the display screen of the electronic equipment with the multi-fold structure such as three folds and the like can be damaged, and the service life of the electronic equipment is influenced. Disclosure of Invention The first aspect of the present application provides a support device. The support device comprises a first shell, a second shell, a third shell, a first folding mechanism, a second folding mechanism and a locking mechanism. The first folding mechanism is connected between the first shell and the second shell, and the first shell and the second shell can be relatively unfolded or relatively folded through the first folding mechanism. The second folding mechanism is connected between the second shell and the third shell, and the second shell and the third shell can be relatively unfolded or relatively folded through the second folding mechanism. When the supporting device is in a fully folded state, the third shell, the first shell and the second shell are sequentially stacked. The locking mechanism is arranged in the second folding mechanism. When the first shell and the second shell are in an unfolding state, and the second shell and the third shell are in an unfolding state, the locking mechanism locks the second folding mechanism so as to prevent the second shell and the third shell from being folded relatively through the second folding mechanism. When the first shell and the second shell are in a completely folded state, the locking mechanism releases the locking of the second folding mechanism, and the second shell and the third shell can be relatively unfolded or relatively folded through the second folding mechanism. In the supporting device, when the first shell and the second shell are in an unfolding state, the locking mechanism locks the second folding mechanism to prevent the second shell and the third shell from being folded relatively through the second folding mechanism, and when the first shell and the second shell are in a complete folding state, the locking mechanism releases the locking of the second folding mechanism to allow the second shell and the third shell to be unfolded relatively or folded relatively through the second folding mechanism. Therefore, the folding mechanism is beneficial to avoiding the damage caused by the fact that a user folds the second shell and the third shell firstly when the first shell and the second shell are not closed. In some embodiments, the second folding mechanism includes a first connector and a mover. The first connecting piece is fixedly connected with the second shell, and the moving piece is in sliding connection with the first connecting piece. The first connecting piece is provided with an accommodating space, the locking mechanism comprises a locking piece and a resetting piece, the locking piece is at least partially accommodated in the accommodating space, and the resetting piece is accommodated in the accommodating space and is connected with the locking piece. The locking member is locked with the moving member when the first housing and the second housing are in the expanded state and the second housing and the third housing are in the expanded state. The first shell is provided with an unlocking piece, and the unlocking piece drives the locking piece to move in a direction away from the moving piece in the process that the first shell and the second shell are switched from an unfolding state to a full folding state, so that the locking piece can unlock the moving piece. In the process that the first shell and the second shell are switched from the fully folded state to the unfolded state, the reset piece drives the locking piece to move towards the direction approaching to the moving piece, so that the locking piece is reset. By introducing the first connecting piece and the moving piece in sliding connection in the second folding mechanism, and the locking piece and the resetting piece in the locking mechanism, the automatic locking and unlocking functions are provided. When the first shell and the second shell are closed, the locking piece and the moving piece are automatically unlocked, and the second shell and the third shell are convenient to fold. The use of the resetting piece is beneficial to ensuring that the locking piece is automatically reset when needed, and improves the convenience and safety of use. In some embodiments, the unlocking member includes a boss protruding from the first housing. The locking mechanism also comprises a pressing piece which is accommodated in the accommodating space, is in
