TECHNICAL FIELD

Embodiments of the present disclosure relate to an insertion and extraction structure, an eyewear and an electronic device.

BACKGROUND

Augmented reality technology integrates real world information and virtual world information “seamlessly”, and allows physical information (visual information, sound, taste, tactile information, etc.) that is difficult to experience in a certain tune and space of the real world to be simulated and then be superimposed with each other by science and technology such as a computer, so that the virtual information is used to the real world and is perceived by human senses, thus achieving a sensory experience that transcends reality. The augmented reality technology not only displays the real world information, but also displays the virtual information at the same time. These two kinds of information complement each other and superimpose each other.

In visual augmented reality, users use virtual reality glasses type displays to multiply fuse the real world and computer pictures. In the design process of virtual reality glasses, an optomechanical component is connected with an end of the glasses, and some structures is needed to realize the connection in the process of connection.

An insertion and extraction structure, an eyewear and an electronic device provided by the present disclosure are described in detail below by illustrating several specific embodiments.

Referring to FIG. 1 and FIG. 2, a schematic structural view of the insertion and extraction structure according to the embodiments of the present disclosure is shown. The insertion and extraction structure includes a main machine assembly 10 and a support assembly 20, and the support assembly includes a fixing member 21. For example, the main machine assembly 10 is any type of electronic component such as a display or any type of non-electronic component. For example, the support assembly 20 is any type of support such as an eyewear leg of an eyewear or a wrist strap of a watch. The embodiments of the present disclosure do not limit the types of the main machine assembly 10 and the support assembly 20.

Referring to FIG. 2 to FIG. 7, the main machine assembly 10 is provided with a first connector 11, the fixing member 21 is provided with a second connector 211, and the main machine assembly 10 is configured to be inserted into or be extracted from the fixing member 21 through cooperation of the first connector 11 and the second connector 211. The first connector 11 has a first limiter portion; for example, the first limiter portion includes a first groove 1111 as shown in FIGS. 3 and 6 and/or includes a first fastener 112 as shown in FIG. 7. The fixing member 21 has a second limiter portion; for example, the second limiter portion includes a top bead 2131 as shown in FIGS. 2, 3 and 6, and/or includes a second fastener 2113 as shown in FIG. 7. The first limiter portion is configured to cooperate with the second limiter portion to realize that the main machine assembly 10 and the fixing member 21 are positionally limited and are fixed in a situation where the main machine assembly 10 is fixed (detachably fixed) by being inserted into the fixing member 21. It should be noted that in order to make the structures such as grooves and through holes in FIG. 3 clear, only partial sectional structures of a part of components in FIG. 3 are shown.

For example, in such a situation that the first limiter portion includes a first groove 111 (FIG. 7 schematically shows a position of the first groove 111 by using a dotted circle) and the first fastener 112 and the second limiter portion includes the top bead 2131 and the second fastener 2113 that is configured to cooperate with the first fastener 112, the first fastener 112 is located at a lateral surface 11C (as shown in FIG. 7) of the first connector 11, and the lateral surface 11C intersects a surface (a first surface 111 as shown in FIG. 2) that is included by the first connector 11 and that faces the second connector 211. For example, the first fastener 112 and the second fastener 2113 may be one or two (as shown in FIG. 7) or more.

For example, in conjunction with FIGS. 2 and 6, the first surface 111 of the first connector 11 is attached to a second surface 2111 of the second connector 211 (these two surfaces are not labeled in FIG. 6). In other embodiments, for example, the first surface 111 and the second surface 2111 are unattached (for example, an orthographic projection of the first surface 111 on a plane where the second surface 2111 is located is outside the second surface 2111), as long as the first connector 11 and the second connector 2111 are configured to cooperate with each other.

In the embodiments of the present disclosure, for example, the second connector 211 is a rotator block (also referred to as a rotator); and for example, the rotator block is configured to be rotatable in a clockwise direction and in an anticlockwise direction indicated by arrows in FIG. 7 with a position of the top bead 2131 as a center of rotation, so that the insertion and extraction structure meets different usage requirements. In the case where the second connector 211 is the rotator block, for example, the fixing member 21 further includes a rotating fixing member 212 and a stir mechanism 213, the rotating fixing member 212 is configured to connect the second connector 211 and a body 23 of the support assembly 20, and the stir mechanism 213 is configured to prevent the first surface 111 of the first connector 11 from moving relative to the second surface 2111 of the second connector 211 in a direction in which the first surface 111 extends.

The insertion and extraction structure will be described in detail below by taking the second connector 211 as the rotator block (for convenience of understanding, the following description will be described by using “rotator block 211”).

In the embodiments of the present disclosure, for example, the support assembly 20 has a first recess 22 configured for accommodating the rotator block 211. The first recess 22 is located in the body 23 of the support assembly 20, and a first through hole 221 is in the first recess 22.

In the embodiments of the present disclosure, for example, in the situation where the main machine assembly 10 is fixed by being inserted into the fixing member 21, the stir mechanism 213 is located in the hollow portion 2122, and an end of the stir mechanism 213 passes through the third through hole 21211 and then connects the first limiter portion (see the first groove 1111 in FIG. 6). The stir mechanism 212 is configured to enter the third through hole 21211 under an action of an external force or is configured to bounce from the third through hole 21211 in the rotating fixing member 212.

In the embodiments of the present disclosure, for example, the second end 2123 of the rotating fixing member 212 has a recessed step structure; the fixing member 21 further includes a fastener structure 214 (for example, a circlip or other type of fastener structure); the fastener structure 214 is configured to be assembled with the recessed step structure of the second end 2123, so as to prevent the recessed step structure of the second end 2123 from passing through the first through hole 221 in the body 23 of the support assembly 20 and to allow the fixing member 21 to rotate with respect to the support assembly 20 under the action of the external force, in the situation where the main machine assembly 10 is inserted into the fixing member 10.

In the embodiments of the present disclosure, for example, the second limiter portion includes the top bead 2131, and the first limiter portion includes the first groove 1111 configured for accommodating the top bead 2131; the first groove 1111 is disposed at the first surface 111 (the surface that is included by the rotator block 211 and faces the main machine assembly 10).

In the embodiments of the present disclosure, for example, the stir mechanism 213 includes the top bead 2131, a spring 2132 and a screw 2133.

In the embodiments of the present disclosure, for example, referring to FIG. 5 and FIG. 6, FIG. 6 is an enlarged view of location A in FIG. 5, a first end 2131A of the top bead 2131 is connected with a first end 2132A of the spring 2132, and a second end 2131B of the top bead 2131 passes through the third through hole 21211 (as shown in FIG. 3) and then is connected with the first limiter portion (referring to the first groove 1111); the top bead 2131 is configured to enter the third through hole 21211 under the action of the external force or is configured to bounce from the third through hole 21211.

In the embodiments of the present disclosure, for example, the screw 2133 is provided with a second groove 2133C (as shown in FIG. 3) at a position where the screw 2133 contacts the second end 2132B of the spring 2132, and the second end 2132B of the spring 2132 is disposed in the second groove 2133C.

In the embodiments of the present disclosure, for example, the hollow portion 2122 has an internal thread that is configured to cooperate with an external thread of the screw 2133, and the screw 2133 is configured to fix the spring 2132 and the top bead 2131 in the hollow portion 2122.

In the embodiments of the present disclosure, in inserting the main machine assembly 10 into the support assembly 20, the main machine assembly 10 gives a lateral surface 2121C (as shown in FIG. 3) of the first end 2121 of the rotating fixing member 212 with a force which has a direction perpendicular to the lateral surface 2121C; at this time, the top bead 2131 is subjected to the force, moves toward the spring 2132 and moves into the hollow portion 2122 under the action of the force; after insertion of the main machine assembly 10 into the support assembly 20 is completed, because the main machine assembly 10 has the first groove 1111 configured to cooperate with the top bead 2131, the top bead 2131 bounces from the third through hole 21211 along a direction from the spring 2132 to the top bead 2131 under an action of the spring 2132 and then is inserted into the first groove 1111, so as to reach an limiting function of the rotator block 211 and the first connector 11.

In the embodiments of the present disclosure, for example, referring to FIG. 7, the second fastener 2113 included by the second limiter portion is, for example, a protruding fastening point, and the protruding fastening point is disposed at the second connector (e.g., the rotator block) 211, and the first fastener 112 included by the first limiter portion is, for example, a fastening groove configured for accommodating the fastening point. Alternatively, in other embodiments, the first fastener 112 included by the first limiter portion is, for example, the protruding fastening point, the protruding fastening point is disposed at the first connector 11, and the second fastener 2113 included by the second limiter portion is, for example, the fastening groove that is configured for accommodating the fastening point.

In the embodiments of the present disclosure, in inserting the first connector 11 into the second connector 211, the fastening point is stuck in the fastening groove in presence of the force being greater than a certain value. In FIG. 7, an assembly view of inside of the insertion and extraction structure is shown, which is not a view of a surface of the insertion and extraction structure.
