Referring to fig. 18-20, fig. 20 is a schematic structural diagram of the first elastic sheet in fig. 18, it should be noted that the structures of the first elastic sheet 710 and the second elastic sheet 720 in this embodiment may be the same or similar, and therefore the structure of the first elastic sheet is illustrated in fig. 20. The first elastic piece 710 includes a connecting portion 711 and an elastic leg portion 712, the connecting portion 711 is configured to be connected to the housing 100 (specifically, the front housing 130) or the circuit board 400 of the electronic device (not shown), and the elastic leg portion 712 extends toward the transmission mechanism 222 and elastically contacts with the transmission mechanism 222 (specifically, an outer wall of the connecting sleeve 222412 of the first connector 22241).

Further, the first resilient tab 710 in this embodiment includes two resilient leg portions 712, and the two resilient leg portions 712 extend from two opposite sides of the connecting portion 711, so that the extending direction of the whole length of the first resilient tab 710 is the same as the sliding direction of the connecting portion 2224 of the transmission mechanism 222, and within the range of the sliding stroke of the connecting portion 2224, the outer wall of the connecting sleeve 222412 of the first connecting portion 22241 of the connecting portion 2224 may be elastically connected to at least one of the two resilient leg portions 712, thereby ensuring that the connecting portion 2224 maintains a continuous resilient connection state with the first resilient tab 710 during the sliding process. That is, within the range of the sliding stroke of the connecting member 2224, the first resilient tab can be ensured to be resiliently connected to the connecting member 2224 at any time, and thus, the connecting member cannot be disconnected.

In addition, in this embodiment, the contact sleeve 222411 may be made of a non-metal material, such as plastic, for the purpose of making the contact sleeve 222411 easily fall off due to dry friction when sliding in contact with the guide bar 2223 (which is generally made of metal material) (the contact sleeve 222411) is also made of metal material, the falling powder may affect the friction coefficient between the two, and the metal powder may also affect other parts inside the electronic device; in addition, the two parts (the contact sleeve 222411 and the guide bar 2223) made of metal are in frictional contact, if lubrication is not proper, the friction coefficient is higher, so that higher pressure is caused to the driving motor, and even the situation of clamping occurs; for this reason, the contact sleeve 222411 may be made of a non-metallic material.

If the material of the contact sleeve 222411 is non-metallic, it will cause the insulation between the guide bar 2223 and the second connector 22242 and the connecting sleeve 222412 of the first connector, therefore, the structure of the first elastic sheet 710 in this application is provided with two elastic legs 712, and the two elastic legs 712 respectively elastically abut against the connecting sleeve 222412 of the first connector and the driving screw 2222.

Similarly, the second resilient tab 720 also includes two resilient leg portions, and the two resilient leg portions extend from two opposite sides of the connecting portion, so that the extending direction of the whole length of the second resilient tab 720 is the same as the sliding direction of the connecting portion 2224 of the transmission mechanism 222, and within the range of the sliding stroke of the connecting portion 2224, the outer wall of the sleeve portion 222421 of the second connecting portion 22242 of the connecting portion 2224 can be elastically connected to at least one of the two resilient leg portions, thereby ensuring that the connecting portion 2224 maintains a continuous resilient state in the sliding process as well as the second resilient tab 720. The two spring legs 712 of the second spring plate 720 are elastically abutted to the sleeve joint portion 222421 of the second connector and the guide bar 2223, respectively, so as to achieve double safety, and ensure that the parts such as the support frame 2221 and the driving motor 221 connected to the guide bar 2223 can be grounded through the spring plate 700 together with the parts such as the camera bracket 223 on the other side (the contact sleeve 222411 is made of non-metal insulation). The detailed structural features of the second elastic sheet 720 in this embodiment are not illustrated, and specific reference may be made to the structure of the first elastic sheet 710.

Referring to fig. 21, fig. 21 is a schematic structural diagram of the sliding/lifting type front-view unit and the front housing, where the sliding extending position of the camera 210 controls the position of the driving device 220 through a signal, and an external structure is also needed to limit the position of the camera 210 for extending and retracting, so as to avoid the camera from being out of position due to inaccurate control of the driving device 220, and also to perform an auxiliary limiting function. In this embodiment, the purpose of limiting the sliding position of the camera 210 is achieved by providing a limiting protrusion on the inner wall of the housing 100. In this embodiment, the limiting protrusions include a first limiting protrusion 1311 and a second limiting protrusion 1312, which are respectively used for limiting the positions of the front camera 210 in the two states of extending out and retracting back to the housing 100.

Alternatively, in the embodiment of fig. 21, the limitation of the extreme sliding position of the camera 210 is realized by providing the first limiting protrusion 1311 on the front shell 130. Specifically, the first limiting protrusion 1311 in this embodiment can limit the sliding position of the camera 210 by limiting the limit sliding position of the connecting part 2224 (specifically, the connecting arm 222422 that supports the second connecting part 22242, please refer to fig. 10). It should be noted that, in other embodiments, a limiting protrusion or other limiting structures may be further disposed on the rear shell 110 or the circuit board 400, as long as the purpose of limiting the sliding position of the camera 210 can be achieved, in this embodiment, only the structure in which the limiting protrusion is disposed on the front shell 130 is taken as an example for description, and the details of the scheme in which the limiting structures are disposed at other positions are also omitted here.

The second limiting protrusion 1312 can limit the limit sliding position of the front camera 210 by supporting the supporting leg 2232 of the camera bracket 223 (specifically, supporting the end of the second supporting leg 22322). Of course, in other embodiments, the second limit protrusion 1312 may also limit the sliding position of the camera 210 by supporting other sliding components of the transmission mechanism 222 of the driving device 220 or other positions of the camera bracket 223. Alternatively, the limiting protrusions (including the first limiting protrusion 1311 and the second limiting protrusion 1312) may be formed on the front case 130 by integral molding, and in some other embodiments, may also be formed by providing limiting posts or limiting screws.

Specifically, the first limit projection 1311 defines the limit extended position of the camera head 210 when contacting the connecting member 2224, and the second limit projection 1312 defines the full retracted position (i.e., the limit retracted position) of the camera head 210 when contacting the supporting leg 2232. Through setting up the physical structure in this embodiment, can play the assistance-localization real-time effect to drive arrangement 220 of camera 210, can avoid simultaneously taking place because of drive arrangement 220 control inaccurate and lead to the condition of camera dislocation.
