Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Referring to fig. 1 to 8, an embodiment of the present invention provides a telescopic mechanism applied to an electronic device, where the electronic device includes a housing 30, and the telescopic mechanism 10 may specifically include the following structure:

the device comprises a driving component 11, a push rod 12, a telescopic bracket 13, a limiting piece 14 and a limiting slide rail 15;

the driving assembly 11 is connected with the push rod 12, and the push rod 12 is connected with the telescopic bracket 13;

the limiting part 14 is fixedly connected to the telescopic bracket 13, the limiting slide rail 15 is fixedly connected to the housing 30, the limiting part 14 is provided with a limiting protrusion 141, and the limiting protrusion 141 is disposed in a slide groove of the limiting slide rail 15 and moves along the slide groove.

Specifically, the telescopic mechanism 10 includes a driving assembly 11, a push rod 12, a telescopic bracket 13, a limiting member 14 and a limiting slide rail 15, and the driving assembly 11 may be a motor and a screw rod. The driving assembly 11 is connected to the push rod 12, as shown in fig. 1, the push rod 12 can be sleeved on the driving assembly 11, and the driving assembly 11 drives the push rod 12 to move. The push rod 12 is connected with the telescopic support 13, as shown in fig. 1, a guide post can be arranged on the telescopic support 13, the spring is sleeved on the guide post, the push rod 12 can be sleeved on the guide post and fixedly connected with the spring, the push rod 12 can compress the spring by moving, so that the telescopic support 13 is pushed to move, and the spring can play a role of buffering. Of course, the push rod 12 can also be directly and fixedly connected with the telescopic bracket 13, and the push rod 12 moves to drive the telescopic bracket 13 to move.

As shown in fig. 2 to 4, the limiting member 14 is fixedly connected to the telescopic bracket 13, for example, by bonding or screwing, and the limiting member 14 limits the start-stop position of the movement of the telescopic bracket 13. As shown in fig. 5, the limit slide 15 is fixedly connected to the housing 30, for example, by bonding or screwing. As shown in fig. 6, the limiting member 14 is provided with a limiting protrusion 141, the limiting protrusion 141 is disposed in the sliding slot of the limiting slide rail 15 and moves along the sliding slot, and fig. 4 shows a schematic view of the limiting member 14 and the limiting slide rail 15 after being assembled. Fig. 7 shows a schematic structural diagram of the limiting protrusion 141, and fig. 8 shows a schematic structural diagram of the limiting slide rail 15, it can be understood that the sliding groove of the limiting slide rail 15 may be an elongated slot-shaped structure along the zero-offset telescopic direction of the telescopic bracket, and therefore, the sliding groove is the zero-offset telescopic direction of the telescopic bracket. Therefore, when the limit projection 141 moves along the sliding groove of the limit slide rail 15, the limit slide rail 15 does not generate an acting force on the limit projection 141. Of course, the two first side surfaces 1411 of the limiting protrusions 141 may be connected by a curved surface, a flat surface or a folded surface, the number of the limiting protrusions 141 may be two or three, and the shape, specification, number, and the like of the limiting protrusions 141 may be set by a person skilled in the art according to actual situations.

Because the limiting protrusion 141 is disposed on the limiting member 14, and the limiting member 14 is fixedly connected to the telescopic bracket 13, the movement locus of the limiting protrusion 141 is the same as the movement locus of the telescopic bracket 13.

The limiting part is fixed on the telescopic support, the limiting slide rail is fixed on the shell of the electronic equipment, the limiting part is provided with a limiting lug, and the limiting lug is arranged in the slide groove of the limiting slide rail and moves along the slide groove. In the telescopic motion process of the telescopic support, the limiting lug can move along with the motion direction of the telescopic support, and if the telescopic support is inclined, the limiting lug can also be inclined. However, the limit projection moves in the limit slide. Therefore, when the limiting convex block is inclined relative to the sliding groove direction of the limiting sliding rail, the sliding groove side wall of the limiting sliding rail applies force to the limiting convex block to correct the movement direction of the limiting convex block, so that the limiting convex block moves along the sliding groove direction of the limiting sliding rail, and the problem that the telescopic support is inclined in the telescopic movement process can be effectively solved.

When telescopic bracket's direction of motion allows to have certain offset along the flexible direction of theory, for example, be fixed with the camera module on the telescopic bracket, the camera module has the permission offset in the concertina movement in-process, and at this moment, spacing slide rail 15 can be elastic slide rail. In addition, when the position-limiting slide rail 15 is a rigid slide rail, in order to allow the telescopic bracket 13 to move within the allowable deviation direction range, an elastic body may be disposed on the sliding groove side wall 151 of the position-limiting slide rail 15, for example, the elastic body may be bonded to the side wall 151, and the elastic body may also be an elastic coating.
