Today's mobile phones have a lens that allows them to have a camera function. The lens needs to be exposed to the outside of the case of the mobile phone, so that the exposed lens is not used = Waiting: exposed to the external environment, so there will be scratches or damage to the lens surface of the lens, except for the flip type, The cap-type and slide-type mobile phones can be shielded and protected by the cover body, and the upright type mobile phone can only be used for one at most; INFLUENCE [New content] Therefore, the object of the present invention is to provide a mobile electronic device that can extend or retract a lens into a casing by pressing. Therefore, the mobile electronic device with the push-type extension and contraction lens comprises a housing, a lens single elastic (four), and a back-stop gear. The housing has an accommodating space 'and an opening communicating with the accommodating space', and the lens unit has a lens and an actuating rod coupled to the lens, and the lens unit is movably disposed on the housing In the accommodating space, it is relatively close to the lens exposure position and the lens burying position. " The elastic member is disposed in the housing and connected to the lens unit. The anti-reverse gear is fixedly positioned in the accommodating space, and can be rotated by the actuating movement of the M 590 590. The anti-reverse gear forms a plurality of in-position positions, and is reversed after being rotated to the respective position. When the lens unit is pushed from the exposed position of the lens to the embedding position of the lens, the elastic element is compressed, and the actuating lever pushes the anti-reverse gear to the clamp position, and the lens unit is locked by the anti-reverse gear Positioning in the buried position of the lens, and then pushing the lens unit again, the actuating rod can push the 4th gear to rotate to the next position, and releasing the pressing force can cause the bomb to recover the force. The lens unit is moved back to the exposed position of the lens. [Embodiment] The detailed description of the preferred embodiments of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 1 to FIG. 3, the preferred embodiment of the present invention is a mobile phone with a camera function, which comprises a casing 丨, a camera unit 2, a single f-element 3, a check gear 4, and other necessary Electronic components (not shown). The phone case! There is an accommodating space u, and an opening 12 (see FIG. 5) which is opened on the casing 1 and communicates with the accommodating space ,, and the other components are disposed in the accommodating space 11. The lens unit 7L 2 has a lens 21, an actuating lever 22 extending from one side of the lens 21 toward the accommodating space 11, and a arranging tooth 220 disposed on the actuating lever 22. In this embodiment, the row of teeth 220 includes three equally spaced spoon teeth and is defined as the first tooth 221, the second tooth 222, and the third tooth, respectively, by the free end of the actuation and "22. 223 'In addition, the first tooth M297590 tooth 221 is also longer than other teeth, the reason of which will be described below. The lens 21 of the lens unit 2 is disposed on the opening 12 and movably disposed in the accommodating space u of the housing 1 and movable between a lens exposure position and a lens burying position. As shown in FIG. 2, when the lens is exposed, the lens 2 protrudes from the opening 12 of the casing 1. When the lens is not in the lens embedding position as shown in Fig. 1, the lens 21 is retracted into the accommodating space. 11 and the top surface of the lens 2 is coplanar with the position of the housing 1 and its opening 12. The housing 1 further has a fixing portion 13 disposed in the accommodating space 11. The fixing portion 13 is a stopper fixed to the inner wall surface of the housing. Further, the elastic member 3 is a compression spring. The elastic S member 3 is disposed between the fixing portion 13 and the lens 21 and is pushed against the lens 21. The check gear 4 is fixedly positioned on the inner wall surface of the casing ,, and is placed in the square and valley work chambers 11. The anti-reverse gear 4 is adjacent to the row of teeth and has a wheel body and four sets of gear teeth 42 disposed equidistantly on the outer edge of the wheel body 41. The gear set 42 is configured to interfere with each of the teeth of the gear teeth 22, and each of the gear sets 42 has two teeth, which are divided into first gear teeth 421 and second gear teeth. 422, and the distance between the two sets of teeth 42 is greater than the spacing of the two teeth 421, 422 of the same set of teeth 42. The backstop gear 4 can rotate as the lens unit 2 moves. Because the lens unit 2 is in the moving stroke, the teeth (10) disposed on the actuating lever 22 push the teeth 421, 422 of the check gear 4 toward the single - Direction rotation. The anti-reverse gear* also forms a plurality of in-position positions, and in this embodiment, the anti-reverse gear 4 is rotated counterclockwise to each in-position position, and the wheel body 41 is also engaged with the anti-reverse mechanism (not shown in FIG. 7 M297590). The counter gear 4 cannot rotate clockwise, but in practice, the implementation of the anti-reverse mechanism is numerous and widely used in the related technical field, so the present embodiment will not be described again. In the embodiment, the reverse gear 4 forms twelve equidistant in-position positions when rotating, and the back-stop gear 4 is rotated from the upper-to-position position to the lower-to-position position by a unit angle, that is, the unit The counter gear 4 is rotated by 3 degrees until the angle is changed. In addition, the wheels * 421 and 422 correspond to the respective in-position positions, and the distance between each of the two teeth and the two teeth 421 and 422 of each of the tooth sets 42 Corresponding to a unit angle, the spacing between the two gear sets 42 corresponds to two unit angles = 60 degrees. 仏疋 = the head unit 2 is closer to the junction of the lens 21 and the actuating lever 22. Edge 23, the blocking edge 23 can be used in the lens When the unit 2 is moved to the exposed position of the head, it is blocked by the peripheral wall of the opening 12, and the stroke of the lens is restricted. In addition, it is noted that the teeth 22 in the present embodiment are between the teeth 42 of the core. Not completely occluded, but partial contact at each end edge, and in a preferred embodiment, it is preferred that the interference force between the tooth sets of the sprocket wheel teeth 220 is slightly larger than that of the elastic element 3 The static compression is better than the original one. The reason will be explained in the following description. As shown in Fig. 1 and Fig. 3, when the lens unit 2 is in the lens exposure position, the first tooth 221 The first teeth on the to-tooth group 42 are called to make the specification and the drawings more clear, and the gear teeth are blocked by the grid, and the lens unit 2 is blocked. The interference occurs with the peripheral wall of the opening η, and the lens unit 2 is prevented from falling out of the opening 12. The lens 21 is pushed by the 8 M297590 and 4 out positions into the accommodating space 11, as shown in Fig. 4, and the first elastic element 3 is compressed by the lens 21 to store energy, and the actuating rod 22, + The second tooth 222 immediately pushes the first tooth 421 and rotates the hour hand of the check gear 4 by one unit angle (also if the back gear 4 is rotated from the original position to the next position), and the second tooth is made The tooth 222 is located between the two teeth 421, 422 of the rim stage 42. After the lens 21 is continuously pressed, as shown in FIG. 5, the lens 21 is retracted from the opening ^2^ to the accommodating space 11, and the elastic member 3 is again compressed during the process: the first tooth 222 continues to push the first wheel The tooth 421 causes the check gear 4 to be re-tacted to a unit angle. At this time, the mirror 帛2 is released, and the elastic member 3 is applied to the lens unit 2 such that the outer edge of the second tooth 222 on the actuating rod 22 and the corresponding second tooth 422 < the outer edge produces a tangential direction The stress, and because the tooth 22G and the gear set 42 are not completely engaged, the restoring force of the elastic element 3 instantaneously released can overcome the interference between the second tooth 222 and the second tooth 422. And the two are elastically staggered, and then, as shown in FIG. $, the second tooth 222 falls toward the direction of the elastic element 3 to the between: the tooth set 42 and the other set of teeth 42 The first tooth 221 having a longer length is blocked by the second gear 422, and is located at the lens embedding position of FIG. The first tooth 221 having a longer length can be hindered from interfering with each of the teeth 42 422 by the elastic member 3. Pressing the lens 21' from the lens embedding position and then compressing the elastic member 3 and retracting the lens 21, the space 11 is retracted, as shown in Fig. 7, during which the second tooth tooth pushes the second tooth 422 causes the check gear 4 to rotate again - a unit angle, while the 9 M297590 second and second teeth 222, 223 are sandwiched between the two sets of teeth 42. When the lens 21 is released, the elastic element 3 is applied to the lens unit 2 again, so that the first tooth 221 and the second tooth 422 of the tooth set 42 generate a tangential stress, even if the second The outer edge of the third tooth 222, 223 and the outer edge of the first tooth 421 of the other tooth set 42 generate a tangential stress, and the restoring force of the elastic element 3 instantaneously released as described above also overcomes the dry " as shown in Fig. 8 and Fig. 9, finally only the longer first tooth 221 is blocked by the first tooth 421 of the other tooth set 42 and returns to the lens exposed position of Fig. 2. It should be noted that, in view of the state in which the elastic member 3 of FIG. 7 is compressed, it can be known that the lens 21 is continuously pushed by the lens embedding position so that the elastic element 3 accumulates the recovery energy between the poles, and in order to avoid the release. After the lens 2 i, the restoring force of the elastic member 3 overcomes the interference between the first tooth 221 and the tooth 421, and the lens unit 2 completely comes out of the housing i because of the force, so the lens unit is used. The barrier edge 23 of 2 can be blocked by the peripheral wall of the opening 12, and the lens unit 2 can be restricted from falling out of the opening 12. In summary, the present invention has a mobile electronic device with a push-type telescopic lens 21, which utilizes the mutual interference between the teeth 220 and the gear sets 42 and simultaneously engages the elastic member 3, so that the lens 21 can be exposed or retracted in the (four) manner. The space η is set, whereby the lens 21 can be used to protect the space 1 from the inside of the lens 1 when it is not in use, thereby avoiding scratches and stains. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change of the novel application and the new description content is Modifications, all still 10 M297590 are covered by this new patent.
