The following describes the telescoping mechanism and the electronic device provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
The embodiment of the application provides a telescopic machanism. Referring to fig. 1 to 9, the telescopic mechanism 30 includes a gear 34, a rack and a link, the gear 34 is engaged with the rack, and one end of the link is connected with the rack; during the rotation of the gear 34, one end of the link connected to the rack moves along a first direction, and one end of the link far away from the rack moves along a second direction, wherein the first direction is perpendicular to the second direction.
In the telescopic machanism 30 that this application embodiment provided, rack and gear 34 meshing, the one end of rack is connected with the connecting rod, when gear 34 rotates and drives the rack flexible, can drive the connecting rod motion, and the direction of motion mutually perpendicular at the both ends of connecting rod, and then under the one end of keeping away from the rack of connecting rod was connected with the condition of other devices, just also can promote the motion of other devices, for example promote other devices and realize concertina movement, reduce the whole volume and the occupation space of other devices.
For example, the telescopic mechanism 30 is applied to an electronic device, and one end of the link, which is far away from the rack, is connected to the housing 10 of the electronic device, and then when the gear 34 rotates, the link is driven to move, the link performs a movement in the same direction as the rack in a first direction, and the movement of the link in a second direction may be to push the housing 10 to perform a telescopic movement, for example, to push the housing 10 to switch between a retracted state and an extended state. Therefore, the electronic equipment can be switched between a large volume and a small volume, and the electronic equipment is more convenient for a user to use and carry.
Further, the housing 10 of the electronic device may be provided with a flexible display 20, and when the housing 10 is switched between the contracted state and the expanded state, the flexible display 20 may be correspondingly switched between a smaller display area and a larger display area. Like this, electronic equipment also can satisfy the user and to the demand of large screen, compare in foldable electronic equipment and have great thickness, this application passes through telescopic machanism 30's motion, realizes electronic equipment casing 10 and flexible display screen 20 display area's change for electronic equipment's thickness is littleer, more facilitates the user to carry.

For example, the first connecting rod 301 may be fixedly disposed relative to the rack, and only the second connecting rod 302 is movable, so that an included angle between the first connecting rod 301 and the second connecting rod 302 is changed; the first connecting rod 301 is fixed, so that the first housing portion 11 will not move, and the second housing portion 12 is pushed to move by the movement of the second connecting rod 302, so that the distance between the first housing portion 11 and the second housing portion 12 is changed. When the first housing part 11 and the second housing part 12 are separated by a first distance, the electronic device is in a first state, and the flexible display screen 20 displays a first display area; when the first connecting rod 301 and the second connecting rod 302 are spaced apart by a second distance, the electronic device is in a second state, and the flexible display screen 20 displays a second display area.
