Description

Sliding-type combination structure

Technical field

The utility model relates to a kind of sliding-type combination structure, relates in particular to the sliding-type combination structure that is used in the slide electronic device.

Background technology

Current electronic installation development, more and more pay attention to the setting of man-machine interface, as mobile phone, mobile computer, handheld game device, personal digital assistant ... wait electronic installation, increase for making the surface that the interface can be set, so derive the electronic installation of collapsible or sliding cover type.Wherein, slide electronic device has noble texture, but also phase shape is comparatively complicated in the mechanism.

Though the present a large amount of employing slip lid pattern of mobile phone, right early stage technology is when sliding, and almost completely armrest promotes, and the feel of operation is not good.The type that is developed had preferable terminal active slip design afterwards, can be pushed the not good problem of feel when promoting to improve when promptly being pushed to end of travel by elasticity.

Good for the feel that makes slip, have the sliding-type combination structure correlation technique in response to and give birth to, see also Fig. 1, the schematic diagram of Fig. 1 prior art sliding-type combination structure 2 first examples.Existing first example, two metal partss 4,6 are assisted propelling movement by elastomer, to produce good slip feel.Because this elastomer is two one-turn coil springs 8, so the stroke that is produced is shorter, and the coil spring 8 easy elastic fatigues of individual pen formula, its shortcoming is arranged in the commodity utilization.

See also Fig. 2, Fig. 2 is the schematic diagram of prior art sliding-type combination structure 2a second example.Second example is to assist by elastomer to push two metal parts 4a, 6a equally, and this elastomer has a plurality of superimposed elastica ring spring 8a.Elastica ring spring 8a has more strong structure and elastic restoring force, and the variable gradient of elastic restoring force is also gentler, and is easy to control desirable elastic restoring force.But a plurality of elastic rings are superimposed together, and except the whole stroke of elastica ring spring 8a was still short, the superimposed thickness that causes also was unfavorable for the lightening design of product.

For increasing the stroke of integral, flexible deformation, see also Fig. 3, Fig. 3 is the schematic diagram of prior art sliding-type combination structure 2b the 3rd example.This case is two metal parts 4b, 6b equally, and also assists propelling movement by elastomer, and different is that elastomer is the wavy elastica ring spring 8b of left and right symmetry.Though this method stroke is bigger, at two metal parts 4b, when 6b slides over each other, the mode of the left and right symmetrical curved arc of wavy elastica ring spring 8b, to produce whole elastic restoring force effect clear, and impracticable.

The utility model content

The purpose of this utility model is used in the electronic installation providing a kind of, can produce the sliding-type combination structure of mutual sliding effect, make two sliding parts when slide relative, have better operating handle, and have desirable elastic restoring force and shift motion, further, designed coil spring has more preferable operation tolerance.

The utility model provides a kind of and is used in as the sliding-type combination structure in the electronic installation of mobile phone.This sliding-type combination structure comprises one first sliding part, one second sliding part and a coil spring.

This second sliding part activity is incorporated into this first sliding part, makes this second sliding part and this first sliding part slide relative.Form a gap between this first sliding part and this second sliding part, this coil spring is established as in this gap.

This coil spring integral body is arc, comprises two ends, and an end of this two end is fixed in this first sliding part, and another end of this two end is fixed in this second sliding part.The arc of this coil spring between this two end is inboard and be extended with a plurality of rotation and elastic rings arranged side by side in regular turn in the same way, further, with this coil spring stage casing is the boundary, have with two be one group and mutually symmetry twine two elastic rings that are provided with, this two elastic ring respectively has a plurality of casts of equal amount respectively.

Wherein, when this first sliding part and this second sliding part slide relative to a primary importance, this coil spring deformation is to produce an elastic restoring force; Follow-up, this elastic restoring force can push these first parts and this second parts slide relative to a second place.Described primary importance is meant the stage casing of stroke, and the second place is meant the two ends of stroke.

Therefore, by sliding-type combination structure of the present utility model, be used for electronic installation as mobile phone, can produce the effect that body slides mutually, utilizing with the stage casing is the boundary, have two one group and mutually symmetry the coil spring of two elastic rings of number multi-turn such as twine, can make integral body have operating handle better when sliding, and have desirable elastic restoring force and shift motion, further, designed coil spring has more preferable operation tolerance.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.
