Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In conventional design, the retractable camera module needs to be electrically connected with a Circuit main Board of the mobile terminal through a Flexible Printed Circuit Board (FPC), so as to realize signal transmission between the retractable camera module and the Circuit main Board.

Wherein, flexible circuit board is the banding, and the width direction of banding flexible circuit board is perpendicular with mobile terminal's screen to make retractable camera module when flexible, flexible circuit board can stretch out and draw back thereupon, does not influence the action of retractable camera module.

However, the band-shaped flexible circuit board is arranged in such a way that the thickness of the mobile terminal is thick. Particularly, as the demand for the camera of the mobile terminal is increased nowadays, for example, the number of arranged cameras is increased, the circuit structure of the retractable camera module is also more complicated, and in contrast, the number of lines in the flexible circuit board is increased, the width of the flexible circuit board is increased, resulting in the thickness of the mobile terminal being larger and larger.

Fig. 1 is a schematic diagram illustrating a front structure of a mobile terminal according to an exemplary embodiment. As shown in fig. 1, the mobile terminal includes a housing 100 and a screen 400 embedded on the housing 100. Fig. 2 is a cross-sectional view of the mobile terminal shown in fig. 1.

Illustratively, referring to fig. 2, the housing 100 includes a middle frame 101 and a rear shell 102, the rear shell 102 covers the middle frame 101, and the screen 400 is embedded in the middle frame 101. Here, the rear case 102, the middle frame 100, and the screen 400 constitute a box-shaped structure. The screen 400 is embedded on the middle frame 101, that is, the edge of the screen 400 is fixed on the middle frame 101. It should be noted that the structure of the housing 100 is an alternative structure, and the housing 100 may also be implemented in other structures.

Fig. 3 is a schematic diagram of the internal structure of the mobile terminal shown in fig. 1. As shown in fig. 3, the mobile terminal further includes a retractable camera module 200 and a circuit board 300 (only a portion of which is shown) disposed in the housing 100, and the housing 100 has a through hole 111 through which the retractable camera module 200 extends. Illustratively, as shown in fig. 3, the through hole 111 is provided on the middle frame 101 (see also fig. 2).

Referring to fig. 3, the retractable camera module 200 is electrically connected to the circuit board 300 through at least two strip-shaped flexible circuit boards 500, the at least two strip-shaped flexible circuit boards 500 are sequentially arranged in a direction parallel to the screen 400, and a width direction of each flexible circuit board 500 is perpendicular to the screen 400.

As shown in fig. 3, in order to ensure that the retractable camera module 200 connected to the flexible circuit board 500 can slide normally, the flexible circuit board 500 herein will be in a bent state as shown in fig. 3, that is, the length of the flexible circuit board 500 is long, so that when the retractable camera module 200 extends out of the housing, it can still be ensured that the retractable camera module 200 and the circuit board 300 are connected sufficiently. As shown in fig. 3, each flexible circuit board 500 is in a bent state, thereby ensuring that each flexible circuit board 500 does not affect the normal sliding of the retractable camera module 200.

Further, as shown in fig. 3, at least two strip-shaped flexible circuit boards 500 may be arranged at intervals. In other implementations, at least two strip-shaped flexible circuit boards 500 may also be arranged in a stack.

In one implementation of the disclosed embodiment, the difference between the widths of any two flexible circuit boards 500 may be less than the width threshold. The width of any two flexible circuit boards is designed to have a small difference, so that the width of each flexible circuit board is ensured to be small, and the thickness requirement on the mobile terminal can be reduced to the greatest extent.

Wherein the width threshold may be set small, for example less than 10%. The percentage here refers to a ratio of a difference in width between the two flexible circuit boards 500 divided by a width of one of the flexible circuit boards 500, for example, divided by a width of the flexible circuit board 500 having a smaller width of the two.

Illustratively, the widths of any two flexible circuit boards are equal, so that the width of each flexible circuit board can be reduced to the maximum extent.

There are multiple signals to be transmitted between the circuit board 300 and the retractable camera module 200, and each signal occupies one line on the flexible circuit board 500. In the embodiment of the present disclosure, the difference between the numbers of lines on any two flexible circuit boards 500 is smaller than the number threshold.

The number of the lines on any two flexible circuit boards is designed to have smaller difference, so that the density of the lines on each flexible circuit board is ensured to be smaller, the short circuit of the lines can be avoided, and the stability of signal transmission is ensured.

Wherein the number threshold may be set small, for example less than 3.

Illustratively, the number of the lines on any two flexible circuit boards is equal, so that the density of the lines on each flexible circuit board can be maximally uniform.

In one implementation of the disclosed embodiment, the number of flexible circuit boards 500 may be 2 or 3. For example, fig. 3 shows a scheme of connecting the circuit board 300 and the retractable camera module 200 by using 2 flexible circuit boards 500.

Adopt 2 or 3 flexible circuit boards to connect circuit mainboard and scalable camera module, on the one hand can reduce every flexible circuit board's width greatly, realize mobile terminal's frivolous design, on the other hand avoids adopting too much flexible circuit board to cause preparation and processing difficulty.

In other implementation manners of the embodiment of the present disclosure, if the number of cameras arranged in the retractable camera module 200 of the mobile terminal is large, the number of the flexible circuit boards 500 may also be greater than 3, so as to ensure that the width of each flexible circuit board is small.

Fig. 4 is a partially enlarged schematic structural view of the flexible circuit board in fig. 3. Referring to fig. 4, at least two strip-shaped flexible circuit boards 500 are electrically connected to the circuit board 300 through a first connector 501, and at least two strip-shaped flexible circuit boards 500 are electrically connected to the retractable camera module 200 through a second connector 502. That is, at least two strip-shaped flexible circuit boards 500 are electrically connected to the circuit board 300 through the same connector, and are electrically connected to the retractable camera module 200 through another connector.

Adopt two connectors to realize being connected of flexible circuit board and circuit mainboard and scalable camera module, avoid directly connecting the assembly that circuit mainboard and scalable camera module caused inconveniently with a plurality of flexible circuit boards.

As shown in fig. 4, in one implementation manner of the embodiment of the disclosure, the first connector 501 (or the second connector 502) plays a role of protecting the flexible circuit board 500 in addition to a role of simultaneously connecting at least two strip-shaped flexible circuit boards 500 to the circuit main board 300 (or the retractable camera module 200). The following description is made with reference to the schematic structural diagram of the first connector provided in fig. 5.

Referring to fig. 4 and 5, the first connection terminal 501 includes a first connection plate 511, and at least two second connection plates 512 electrically connected to the first connection plate 511, the first connection plate 511 is parallel to the screen 400 and electrically connected to the circuit main board 300, the second connection plates 512 are perpendicular to the screen 400, and the at least two second connection plates 512 are electrically connected to the at least two strip-shaped flexible circuit boards 500 in a one-to-one correspondence.

In this implementation, the width direction of flexible circuit board is perpendicular with the screen, if direct connection to with the parallel circuit mainboard of screen on, will probably cause the flexible circuit board to take place the distortion, and can guarantee through first connector that whole flexible circuit board is connected to the circuit mainboard smoothly under the unchangeable condition of direction on. In the first connecting head, the first connecting plate for connecting the circuit main board is parallel to the screen, and the second connecting plate for connecting the flexible circuit board is vertical to the screen, so that the electric connection is realized under the condition that the directions of the flexible circuit board and the circuit main board are not changed; and set up two at least second connecting plates on the connector, be connected with two at least banded flexible circuit board one-to-one electricity respectively to guarantee on the signal homoenergetic of each flexible circuit board can transmit the circuit mainboard.

As shown in fig. 5, the first connection plate 511 and the second connection plate 512 are connected to the main body 513 of the first connection head 501, the first connection plate 511 and the main body 513 are in the same plane, and the second connection plate 512 is disposed at a side of the main body 513 and is perpendicular to the main body 513.

The first connecting board 511 has a first terminal electrically connected to the circuit board 300, the second connecting board 512 has a second terminal electrically connected to the flexible circuit board 500, and the main body 513 has a trace for electrically connecting the first terminal of the first connecting board 511 to the second terminal of the second connecting board 512. The number of the traces is equal to the number of the first terminals, which is equal to the sum of the number of the second terminals on all the second connection plates 512.

Illustratively, the main body 513 includes at least two parallel-arranged sides on which the at least two second connection plates 512 are respectively disposed. In this way, the at least two second connection plates 512 are also arranged in parallel, facilitating connection with the at least two flexible circuit boards 500 simultaneously.

In other implementation manners of the embodiment of the present disclosure, the first connection joint 501 may also be implemented by using other structures, for example, the structural composition of the first connection joint 501 is the same as that in fig. 5, but the position relationship of the second connection plate 512 is different from that in fig. 5, for example, the second connection plate 512 and the main body 513 are in the same plane, and for example, the second connection plate 512 is disposed obliquely with respect to the main body 513.

Referring again to fig. 4, in the embodiment of the present disclosure, the second connector 502 and the first connector 501 may have the same structure. The first connector and the second connector are designed by adopting the same structure, so that the design and the processing are both more convenient.

As shown in fig. 4, the second connecting head 502 includes a third connecting plate 521 and at least two fourth connecting plates 522 electrically connected to the third connecting plate 521, the third connecting plate 521 is parallel to the screen 400 and electrically connected to the retractable camera module 200, the fourth connecting plates 522 are perpendicular to the screen 400, and the at least two fourth connecting plates 522 are electrically connected to the at least two strip-shaped flexible circuit boards 500 in a one-to-one correspondence manner.

The third connecting plate 521 is parallel to the screen 400, that is, the plane of the third connecting plate 521 is parallel to the plane of the screen 400, and the fourth connecting plate 522 is perpendicular to the screen 400, that is, the plane of the fourth connecting plate 522 is perpendicular to the plane of the screen 400.

Of course, the second connector 502 is not limited to the structure shown in fig. 4, similar to the first connector 501.

Referring to fig. 3 again, the retractable camera module 200 includes a mounting base 201 and a camera 202 located on the mounting base 201, and the mounting base 201 is slidably disposed on the housing 100 along a sliding track.

The mounting seat 201 has an end opposite to the through hole 111 and is provided with a receiving groove 211, and when the retractable camera module 200 is in a retracted state, components in the mobile terminal are received in a cavity formed by the receiving groove 211 and the housing 100.

The holding tank has been seted up through the one end at the mount pad through-hole dorsad, arranges other devices in the position that the holding tank corresponds, can not reduce the bearing strength of mount pad on the one hand, even on the other hand when scalable camera module is in the shrink state, the mount pad can not influence the components and parts in the holding tank yet, has saved mobile terminal inner space.

In an implementation manner of the embodiment of the present disclosure, a component in the mobile terminal may be a rear camera of the mobile terminal. Set up the rear camera through seting up the holding tank on the mount pad, can save the rear camera and arrange required space.

Generally, the scalable camera module 200 that this disclosure provided is leading camera, and its purpose is avoided setting up leading camera in mobile terminal's front, influences mobile terminal's comprehensive screen design. The mobile terminal further comprises one or more rear cameras besides the front camera, and the rear cameras are usually arranged at positions close to the top of the mobile terminal, so that the positions of the accommodating grooves 211 provided by the embodiment of the disclosure are just close to the positions of the rear cameras, and therefore, the bearing strength of the mounting seat 201 cannot be reduced on one hand, and on the other hand, the space required for arranging the rear cameras can be saved by arranging the accommodating grooves 211 on the mounting seat 201.

In other implementations, the components in the mobile terminal may also be other components, such as various sensors in the mobile terminal.

As shown in fig. 3, the camera 202 is disposed at one end of the mount 201 facing the through hole 111, and the sliding track of the mount 201 passes through the through hole 111, so that the camera 202 can be carried out of the housing by the mount 201 from the through hole 111 when the mount 201 slides.

Fig. 6 is a separate structural schematic view of the mount in fig. 3. Referring to fig. 6, the mounting base 201 includes a protruding portion 201A and a sliding portion 201B connected to each other, the camera 202 is located at the protruding portion 201A, the receiving groove 211 is located at the sliding portion 201B, and the sliding portion 201B has a limiting structure. The limiting structure is used for limiting the moving range of the camera 202. Wherein, the distance of extension 201A and through-hole 111 is less than the distance of sliding part 201B and through-hole 111, and through setting up limit structure restriction sliding part and stretching out the through-hole, guarantee that whole scalable camera module can not deviate from completely in the casing.

As shown in fig. 6, in one implementation, the sliding portion 201B can be designed to be wider to realize the aforementioned limit structure.

Illustratively, the width of the protruding portion 201A parallel to the first side is smaller than or equal to the width of the through hole 111, and the width of the sliding portion 201B parallel to the first side is larger than the width of the through hole 111, where the first side is a side of the housing where the through hole 111 is disposed, so that it can be ensured that the protruding portion 201A can protrude out of the mobile terminal with the camera 202 during sliding, and the sliding portion 201B can well limit the sliding stroke because its own width is limited in the housing and does not protrude out.

As shown in fig. 6, the sliding portion 201B with the receiving cavity 211 can be in a concave shape, so as to ensure that other components can be disposed in the middle of the receiving cavity 211, and ensure that the rest portion is sufficient for carrying and sliding.

Of course, the structure shown in fig. 6 is only an example, and in other implementations, the mounting seat may be provided in other regular or irregular shapes as long as the above-described functions can be achieved.

Fig. 7 is a detailed structural schematic diagram of the retractable camera module shown in fig. 3. The sliding function of the retractable camera module 200 will be described with reference to fig. 3 and 7.

As shown in fig. 3 and 7, the rear shell 102 is provided with a slide rail 121, one surface of the mounting base 201 facing the rear shell 102 is provided with a slide groove 212 matched with the slide rail, and the slide rail 121 is clamped in the slide groove 212, so that the retractable camera module 200 can be realized.

In order to facilitate the sliding of the retractable camera module 200, the sliding rail 121 is disposed on the rear housing 102, the sliding groove 212 is disposed on the mounting seat 201 in a matching manner, the sliding of the mounting seat 201 is realized by the matching of the sliding rail and the mounting seat, and the design is simple and the manufacture is convenient.

Since the retractable camera module 200 needs to slide along a direction perpendicular to the first side and opposite to the through hole 111, the sliding rail 121 provided in the embodiment of the present disclosure is also arranged along a direction perpendicular to the first side, that is, the length direction of the sliding rail 121 is perpendicular to the first side of the middle frame 101 provided with the through hole 111, so as to ensure that the camera 202 can extend out of the mobile terminal when the mounting base 201 slides on the sliding rail.

Referring to fig. 3 and 7, two slide rails 121 arranged in parallel at intervals are disposed on the rear shell 102; correspondingly, two sliding grooves 212 are arranged on the mounting seat 201.

By providing two slide rails 121, it is ensured that the mounting seat 201 does not directly contact the rear housing 102, thereby reducing friction.

As shown in fig. 7, two sliding rails 121 are symmetrically arranged on two sides of the through hole 111, so that both sides of the mounting seat 201 are supported, and sliding stability is realized. The accommodating groove 211 is located between the two sliding rails 121, so that the contact and the support of the mounting seat 201 and the sliding rails 121 are not affected, and the stability is ensured.

Referring again to fig. 7, the mounting seat 201 is provided with a mounting groove 214, the camera head 202 is disposed in the mounting groove 214, and an opening of the mounting groove 214 is sealed by a sealing ring 215. In this embodiment, the camera 202 is sealed by the seal ring 215, and the camera 202 is prevented from being affected by dust or the like.

In scalable camera module 200, the outside of sealing washer 215 can also be equipped with transparent cover plate, with the whole cover of camera and sealing washer, guarantees the intensity of whole module.

Further, the mounting groove 214 is a groove located on the side of the extension 201A of the mounting seat 201 facing the screen 400, and the mounting groove 214 needs to be provided with the second connector 502 in addition to the camera 202. After the connection of the second connector 502 and the connection line of the camera 202 is completed, the second connector 502 and the camera 202 are installed in the installation groove 214, and then are sealed and fixed by the sealing ring 215, and the second connector 502 and the camera 202 are clamped on the installation seat 201.

Therefore, the second connector 502 is located between the mounting groove 214 and the sealing ring 215.

In order to facilitate the flexible circuit board 500 to be led out from the second connector 502, a groove or a gap for routing the flexible circuit board 500 may be correspondingly disposed on the mounting base 201.

Referring again to fig. 3, the retractable camera module 200 further includes a driving assembly 203, and the driving assembly 203 is used for driving the mounting base 201 to slide. In the implementation mode, the driving assembly is arranged to drive the mounting seat to slide, so that the telescopic action of the telescopic camera module is realized.

Referring to fig. 3 and 7, the driving assembly 203 may include a motor 231, a lead screw 232, and a push rod 233. The output end of the motor 231 is connected with one end of the screw rod 232, one end of the push rod 233 is clamped in the mounting seat 201, the other end of the push rod 233 is provided with a screw hole 234, and the other end of the screw rod 232 is in threaded connection with the push rod 233 through the screw hole 234. Thus, the motor 231 rotates to drive the lead screw 232 to rotate, the lead screw 232 rotates to be converted into linear motion of the push rod 233 through threads, the mounting seat 201 can be driven to slide, and meanwhile, the structure of the driving assembly 203 can limit the moving range of the camera 202.

Of course, the structure of the driving element 203 is only an example, and the structure can ensure that the occupied space is small, which is beneficial to the light and thin design of the mobile terminal. In other examples, the threaded screw design may be replaced by another way as long as the mounting base can be driven to move linearly, for example, a rack-and-pinion design is adopted, for example, a rack is arranged on the side of the mounting base, and a pinion meshed with the rack is arranged on the output shaft of the motor, so that the rotation of the motor is converted into the linear movement of the rack, and the mounting base 201 can be driven to slide.

In one implementation of the disclosed embodiment, the connection between the driving assembly 203 and the mounting seat 201 may have a shock absorbing member. The design can realize the elastic connection between the driving component and the mounting seat, thereby reducing the collision force between the mounting seat and the driving component in the sliding process and playing a role in buffering and damping.

The aforementioned shock-absorbing member may be a spring. Illustratively, a groove 213 is provided on the mounting base 201, one end of the push rod 233 is disposed in the groove 213, a spring 235 that expands and contracts in a direction parallel to the aforementioned slide trajectory is disposed in the groove 213, and the spring 235 is located between a side wall of the one end of the push rod 233 and a side wall of the groove 213.

The design can realize the elastic connection of the push rod 233 and the mounting seat 201, so that the collision force between the mounting seat 201 and the push rod 233 in the sliding process is reduced, and the buffer and shock absorption effects are achieved.

As shown in fig. 7, in order to secure the force of the spring 235 to the push lever 233, a protrusion 233A is provided on a side wall of one end of the push lever 233, and the protrusion 233A is caught in one end of the spring 235.

In the disclosed embodiment, the groove 213 may be disposed above one of the slide rails 121. The groove 213 is a groove formed on an end surface of the mounting base 201 opposite to the through hole 111, and the spring 235 can be inserted into the groove; meanwhile, a strip-shaped opening is formed in the side wall of the groove 213 facing the lead screw 232, so that one end of the push rod 233 extends into the groove 213, and the push rod 233 can slide for a certain distance. After the push rod 233 is put in, the spring 235 is defined between the groove 213 and the push rod 233.

When the screw rod 232 rotates to drive the push rod 233 to move towards the through hole 111, the spring 235 starts to compress, and when the spring 235 is compressed to the shortest, the push rod 233 starts to push the mounting seat 201 to move; when the screw rod 232 rotates to drive the push rod 233 to move back to the through hole 111, the spring 235 starts to extend, and when the spring 235 extends to the longest, the push rod 233 further pushes the mounting seat 201 to move reversely. It should be noted that the length of the belt-shaped opening on the side wall of the groove 213 can ensure that the spring 235 pushes the rod 233 to move freely during the extension and contraction process, thereby ensuring the damping effect.

The aforementioned recess 213 is a threaded hole at the opening (i.e. at an end face of the mounting base 201 facing away from the through hole 111). Fig. 8 is a side view of the collapsible camera module shown in fig. 3. Referring to fig. 8, a screw 236 is disposed in the threaded hole, and the screw 236 is screwed into the threaded hole and then fixed. The push rod 233 is provided with a through hole, and the screw 236 passes through the through hole of the push rod 233, so that the push rod 233 is slidably fitted over a portion of the screw 236 extending from the screw hole.

By providing the screw 236, the push rod 233 can be restricted from moving in a direction parallel to the slide trajectory.

In other implementations, the screw 236 may be replaced by another structure capable of being fixed at the opening, as long as the portion thereof extending into the groove can be used for the push rod 233 to slide.

In addition, the groove 213 and the spring 235 cooperate with the push rod 233 to limit the travel of the mounting seat in a direction away from the through hole 111, which forms part of the aforementioned limit structure.
