Description

Automatic telescopic device applied to small equipment

The technical field is as follows:

the utility model relates to an automatic telescoping device specifically relates to an automatic telescoping device who is applied to on the small-size equipment.

Background art:

at present, the function requirement of common electronic products is higher and higher, the volume requirement is smaller and smaller, the typical product is handheld devices such as mobile phones, the requirement is light, small and thin, under the condition of the small portable device, an automatic telescopic device is often designed in the volume, for example, a camera and a hardware sensor are automatically stretched and hidden, at present, individual devices (for example, an oppo mobile phone) are provided with the automatic telescopic device of the camera, the devices adopt a screw rod principle, and the defects are that: the lead screw scheme adopts a motor, a lead screw assembly and a guide rail, a complex lead screw assembly is needed, the required processing precision is high, the installation mode also needs to consider a plurality of factors such as balance, shockproof stability and the like, so the installation is complex, and the shockproof property is poor! The guide rail mode must ensure stability by using a double-sided guide rail. Meanwhile, the occupied space is large, the small-sized equipment is greatly limited, and the cost is high.

The utility model has the following contents:

to the defect that exists among the prior art, the utility model provides a be applied to automatic telescoping device on the small-size equipment, simple structure is small and exquisite, simple to operate, and is durable lastingly, and occupation space is little, is particularly suitable for using in portable product.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

an automatic telescopic device applied to small equipment comprises a motor, a guide wheel, a sliding module and a guide rail, wherein the motor is matched with the guide wheel; the motor rotates to drive the guide wheel to rotate integrally, and the guide wheel drives the sliding module to move up and down in the effective range of the guide rail.

Further, the stroke and the sliding speed of the sliding module are designed according to different guide grooves in the guide wheel.

Furthermore, the motor, the guide pulley, the guide rail is fixed in the body of small-size equipment, flexible part is fixed on the slip module, and slip module one end sets up in the guide slot, and the other end sets up in the guide rail.

Furthermore, the sliding module is of a T-shaped structure, the end head is arranged in the guide rail in a block shape, and the tail end is arranged in the guide groove in a round rod shape.

Adopt above-mentioned technical scheme, compared with the prior art, the utility model, have following advantage:

1. the occupied volume is small, the square shape is basically, and the volume is concentrated.

2. The transmission mechanism is simple in composition, only the scheme of the guide wheel and the guide rail is needed, the transmission mechanism is simple, the boundary point can be flexibly controlled, and the guide rail can be a single-side guide rail.

3. The cost is low, and the simple 1/2 that has decided the cost of this scheme drive mechanism is the lead screw scheme is fit for the volume production.

Description of the drawings:

the accompanying drawings, which are described herein, serve to provide a further understanding of the invention and constitute a part of this specification, and the exemplary embodiments and descriptions thereof are provided for explaining the invention without unduly limiting it. In the drawings:

fig. 1 is a schematic structural diagram of an embodiment of the present invention;

FIG. 2 is a schematic diagram of the operation of the embodiment of the present invention;

the specific implementation mode is as follows:

in order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-2, is an embodiment of the present invention.

As shown in fig. 1-2, an automatic telescopic device applied to small-sized equipment comprises a motor 1, a guide wheel 2 provided with a guide groove 21, a sliding module 3 and a guide rail 4 which are matched with each other; wherein, motor 1 rotates and drives 2 integrative rotations of guide pulley, and guide pulley 2 drives sliding module 3 and reciprocates in 4 effective limits of guide rail.

In a specific application, the stroke and the sliding speed of the sliding module are designed according to different guide grooves in the guide wheel.

The structure can be installed in small-sized equipment such as a mobile phone, the motor, the guide wheel and the guide rail are fixed in the body of the small-sized equipment, the telescopic component is fixed on the sliding module, one end of the sliding module is arranged in the guide groove, and the other end of the sliding module is arranged in the guide rail.

Specifically, the sliding module 3 may be a T-shaped structure, with a block-shaped end disposed in the guide rail 4 and a round bar-shaped end disposed in the guide groove 21.

The utility model discloses it is small to occupy, and the space 10mm that above-mentioned scheme probably occupied 5mm 4 mm's height is square basically, and the volume is concentrated, and our actual measurement space of lead screw of prior art is 20mm 8mm 4mm, because the length ratio that so needs of stroke is longer to the needs of guaranteeing, has very big restriction in the small-size equipment. The transmission mechanism is simple in composition, the scheme only needs a scheme of a guide wheel and a guide rail, the transmission mechanism is simple, boundary points can be flexibly controlled, the existing lead screw scheme adopts a motor, a lead screw assembly and a guide rail, a complex lead screw assembly is needed, the required processing precision is high, and a plurality of factors need to be considered in the installation mode, so that the installation is complex, and the shock resistance is poor! The rail approach also requires a double sided rail. The cost is low, and the simple 1/2 that has decided the cost of this scheme drive mechanism is the lead screw scheme is fit for the volume production.

While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
