Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

Please refer to the functional assembly 100 shown in FIGS. 1 to 4 , which includes a housing 10 , a sliding seat 20 , a rack 30 , a gear 40 and a motor 50 . The sliding seat 20 is connected with the housing 10 , and the sliding seat 20 can slide relative to the housing 10 along a first direction 001 to extend or retract the housing 10 . The sliding seat 20 is also provided with a camera module 60 . The camera module 60 can be extended or hidden in the casing 10 when the camera module 60 is retracted and slid with the sliding seat 20 . Both the gear 40 and the motor 50 are disposed inside the casing 10 . The motor 50 is fixed inside the casing 10 , and the gear 40 is rotatably disposed inside the casing 10 . The motor 50 is used to drive the gear 40 to rotate. The rack 30 is elastically connected with the sliding seat 20 . A first elastic member 71 is disposed between the rack 30 and the sliding seat 20 along the first direction 001 . The first elastic member 71 makes the rack 30 abut on the sliding seat 20 along the first direction 001 , and the rack 30 is stationary relative to the sliding seat 20 . That is, under the connection action of the first elastic member 71 , there is no relative displacement between the rack 30 and the sliding seat 20 . The gear 40 is matched with the tooth profile of the rack 30 , and the rack 30 and the gear 40 mesh with each other.

When the sliding seat 20 is in the initial position, the gear 40 and the rack 30 mesh with each other but do not slide. The rack 30 is relatively stationary with the sliding seat 20 through the action of the first elastic member 71 . The sliding seat 20 is accommodated inside the casing 10 . When the motor 50 drives the gear 40 to rotate along the first rotation direction 003 , the rotating external teeth of the gear 40 are engaged with the teeth 33 of the rack 30 to drive the rack 30 to slide. The rack 30 pulls the sliding seat 20 to slide together under the action of the first elastic member 71 . The first elastic member 71 is not greatly deformed when being driven by the motor, so that the rack 30 and the sliding seat 20 remain relatively stationary and slide together. With the continuous driving output of the motor 50 , the gear 40 continues to rotate so that the rack 30 slides, and finally drives the sliding seat 20 to slide out of the housing 10 . The camera module 60 disposed on the sliding seat 20 also extends out of the casing 10 to realize shooting (see FIG. 5 ).

On the contrary, when the sliding seat 20 extends out of the housing 10 , the motor 50 drives the gear 40 to rotate along the second rotation direction 004 . The second rotation direction 004 and the first rotation direction 003 are opposite to each other. The gear 40 drives the rack 30 to slide in the opposite direction, and the rack 30 pushes the sliding seat 20 to slide together under the action of the first elastic member 71 . The first elastic member 71 is not greatly deformed when it is driven by the motor, so that the rack 30 and the sliding seat 20 remain relatively static and slide together. With the continuous driving output of the motor 50, the gear 40 keeps rotating relative to the rack 30, and the rack 30 gradually slides back to the initial position meshed with the gear 40, thereby pushing the sliding The seat 20 retracts the housing 10 . The camera module 60 disposed on the sliding seat 20 is also retracted into the casing 10 to achieve concealment.

In the functional assembly 100 of the present application, the camera module 60 is hidden in the casing 10 along with the sliding seat 20 . Through the elastic connection between the rack 30 on the sliding seat 20 and the gear 40 rotatably fixed on the casing 10 , specifically, the gear 40 rotatably connected inside the casing 10 Driven by the motor 50 fixed inside the casing 10 , the rack 30 meshed with the rack 30 is driven to slide by a rotating motion. The rack 30 pulls the sliding seat 20 to slide along the first direction 001 under the connection of the first elastic member 71 , so that the camera module 60 fixed on the sliding seat 20 is The casing 10 is extended or retracted along with the sliding seat 20 . After extending out of the casing 10 , the camera module 60 is released from the previous hidden state, and the shooting function is realized. On the contrary, after the casing 10 is retracted, the camera module 60 is in a hidden state and is protected by the casing 10 .

It can be understood that the driving of the gear 40 by the motor 50 may be that the motor 50 directly drives the rotation of the gear 40 , or a transmission device may be provided between the motor 50 and the gear 40 to The separation of the motor 50 and the gear 40 makes the space size of the functional assembly 100 of the present application more reasonable and easy to arrange. There are many implementations of the above-mentioned transmission device, and the traditional gearbox, chain drive, belt drive, link mechanism, etc. can all realize the drive of the gear 40 by the motor 50, which is not regarded as the protection in this application here. Highlights are described.

It can be understood that, for the control of the gear 40 by the motor 50, the functional component 100 of the present application can also be introduced into a control unit, and the sliding action of the rack 30 can be monitored by a position sensor, or the sliding action of the gear rack 30 can be monitored by an angle sensor. The rotation angle of the gear 40 (not shown in the figure). The control unit is configured to receive the position information of the rack 30 or the rotation angle information of the gear 40 collected by the position sensor or the angle sensor, so as to determine that the sliding seat 20 is currently relative to the housing. The specific position of the body 10 is further controlled to control the relative position of the camera module 60 relative to the casing 10 .

It can be understood that, during the sliding process of the sliding seat 20 with the rack 30, due to the large elastic force of the first elastic member 71, it is not affected by the output power of the motor 50, and a large occurrence occurs. Therefore, there is no large relative displacement between the rack 30 and the sliding seat 20 , and the sliding seat 20 can generate a linkage displacement with the sliding of the rack 30 . And because the elastic force of the first elastic member 71 is relatively large, it can be regarded as a rigid connection in this process. In this way, the sliding response time of the sliding seat 20 with the sliding of the rack 30 is short, and the rapid extending and retracting actions of the camera module 60 can be realized.

It can be understood that with reference to FIG. 9 , the casing 10 further includes a bearing plate 101 , and the bearing plate 101 is fixedly connected inside the casing 10 . Components such as the motor 50 are disposed on the carrier plate 101 to realize the fixing of the components such as the motor 50 relative to the housing 10 . It can be understood that the carrier board 101 can be used as a middle plate of the electronic device.

In some embodiments, see FIGS. 3 and 4 , the sliding seat 20 includes a first surface 21 facing the rack 30 . The first surface 21 extends along the first direction 001 . The first surface 21 is provided with a resisting portion 22 . A direction perpendicular to the first direction 001 is defined as a second direction 002 . In the second direction 002 , the rack 30 is located between the abutting portion 22 and the gear 40 . The rack 30 includes a first surface 31 and a second surface 32 opposite to each other, and both the first surface 31 and the second surface 32 extend along the first direction 001 . The first surface 31 is provided with the tooth portion 33 , and the tooth portion 33 is used for meshing with the gear 40 . The functional component 100 is further provided with a second elastic member 72 , and the second elastic member 72 is connected between the first surface 21 and the second surface 32 . The second elastic member 72 is used to provide elastic force for the rack 30 to move toward the sliding seat 20 along the second direction 002 . That is, the second elastic member 72 extends along the second direction 002 . The resisting portion 22 also extends along the second direction 002 together with the second elastic member 72 . Under the pulling of the second elastic member 72 , the second surface 32 abuts on the abutting portion 22 , that is, the rack 30 and the sliding seat 20 are relatively stationary in the second direction , without mutual displacement.

In the embodiment of the present application, the first elastic member 71 and the second elastic member 72 are both configured as springs. It can be understood that, in other embodiments, the first elastic member 71 and the second elastic member 72 may also be some other elastic elements, such as shrapnel, disc springs, gas-liquid piston rods, etc. This application does not make any special limitation here.

Further, the sliding seat 20 is provided with a limiting portion 23 . The limiting portion 23 is connected with the rack 30 in the first direction 001 through the first elastic member 71 , that is, the sliding seat 20 and the rack 30 are connected through the first elastic member The connecting position of 71 is set at the limiting portion 23 . The second surface 32 is provided with a groove 34 . The groove 34 has a certain depth to at least partially accommodate the abutting portion 22 . When the resisting portion 22 resists on the second surface 32 , the position of the groove 34 relative to the resisting portion 22 is closer to the limiting portion in the first direction 001 twenty three. That is, the groove 34 is closer to the limiting portion 23 than the resisting portion 22 in the first direction 001 . In the embodiment of FIG. 1 , the limiting portion 23 is located below the rack 30 , that is, the groove 34 is also located below the resisting portion 22 relative to the resisting portion 22 .

After the sliding seat 20 protrudes out of the housing 10 , if the sliding seat 20 accidentally falls off, the sliding seat 20 will be subjected to an external force in the direction of the limiting portion 23 . At this time, the motor 50 holds the gear 40 , and the rack 30 cannot slide relative to the gear 40 due to the meshing with the gear 40 . The gear 40 is rotationally connected with the housing 10 , so the rack 30 cannot slide relative to the housing 10 . The length of the first elastic member 71 connecting the sliding seat 20 and the rack 30 changes under the action of external force. Since the first elastic member 71 is disposed along the first direction 001, the first elastic member 71 elastically connects the rack 30 and the sliding seat 20, so the first elastic member 71 is located along the first direction 001. After the length direction of the first direction 001 is changed, the distance between the rack 30 and the limiting portion 23 is increased. That is, the sliding seat 20 moves relative to the rack 30 , and the abutting portion 22 slides to a position flush with the groove 34 with the movement of the sliding seat 20 (see FIG. 6 ). With the elastic force provided by the second elastic member 72 toward the first surface 21 , the rack 30 can accommodate at least part of the abutting portion 22 into the groove 34 . Taking the sliding seat 20 as a reference, the rack 30 moves toward the sliding seat 20 along the second direction 002 (see FIG. 7 ). Therefore, the rack 30 is disengaged from the gear 40 through the movement in the second direction 002, and the sliding seat 20 is not constrained by external force in the first direction 001, and can follow The external force received in the direction of the limiting portion 23 slides freely relative to the housing 10 , thereby realizing the buffering of the external force by the sliding seat 20 . The sliding seat 20 also protects the camera module 60 from damage through buffering.

Since the elastic force of the first elastic member 71 is relatively large, when the second elastic member 72 pulls the rack 30 toward the sliding seat 20 in the second direction 002, the first elastic member 71 is subject to twisting in the second direction 002 . According to the characteristic that the elastic element automatically returns to a free state when it is not subjected to external force, the first elastic member 71 will twist the rack 30 back to face the limiting portion along the first direction 001 23 position. That is, the rack 30 will be pulled back to its original position by the first elastic member 71 . After the rack 30 returns to the initial position, its distance relative to the gear 40 is also restored, and the rack 30 will resume the meshing state with the gear 40 again, resulting in the sliding seat 20 In the first direction 001, it is again restricted by external force and cannot slide freely to achieve buffering. To this end, in some embodiments, a resisting surface 221 is further provided on the resisting portion 22 , the resisting surface 221 extends along the second direction 002 , and the resisting surface 221 is located on the resisting surface 221 . The end of the locating portion 22 away from the limiting portion 23; correspondingly, a locating surface 341 is provided on the groove 34 to cooperate with the abutting surface 221, and the locating surface 341 also extends along the second direction. . When at least part of the abutting portion 22 is received into the groove 34 , the first positioning surface 341 is in contact with the abutting surface 221 , and the abutting surface 221 restricts the positioning surface 341 in the When sliding toward the limiting portion 23 in the first direction 001, the first elastic member 71 suffers resistance due to the cooperation between the abutting surface 221 and the positioning surface 341, and cannot return to its free state . Therefore, the rack 30 is no longer displaced relative to the sliding seat 20 in the first direction 001 , and the rack 30 always presses the rack under the action of the second elastic member 341 . The portion 22 is received in the groove 34 and remains stationary in the second direction 002 avoiding re-engagement with the gear 40 .

Because the rack 30 and the sliding seat 20 are relatively stationary in the second direction 002, in order to restore the initial state after the sliding seat 20 finishes the buffer function, the rack 30 and the gear 40 are realized. For re-engagement, in an embodiment, a top block 11 is also arranged in the housing 10 . The top block 11 is fixed inside the housing 10 , and the top block 11 is located between the first surface 21 and the second surface 32 in the second direction 002 . The dimension of the top block 11 in the second direction 002 is greater than or equal to the height dimension of the abutting portion 22 . That is, in the second direction 002 , the outer contour of the top block 11 is flush or closer to the proximal end of the rack 30 than the abutting portion 22 is toward the proximal end of the rack 30 . . With this arrangement, when the sliding seat 20 is retracted into the casing 10 , the second surface 32 is in contact with the top block 11 , and the abutting portion 22 is due to the action of the top block 11 . And the groove 34 is disengaged. Therefore, the contact between the abutting surface 221 and the positioning surface 341 is also disengaged, and the first elastic member 71 is no longer constrained and can be restored to a free state. The first elastic member 71 that is restored to a free state pulls the rack 30 back in the second direction 002 , and the rack 30 is restored to mesh with the gear 40 . Thus, the functional component 100 can be restored to the initial state.

It should be noted that the top block 11 is fixed inside the casing 10 , and the top block 11 and the second surface 32 are at a section when the sliding seat 20 extends out of the casing 10 . Contact will still occur within distance. In order to eliminate the influence of the top block 11 on the sliding action of the sliding seat 20 , it is necessary to smooth the contact position of the top block 11 and the second surface 32 . That is, when the sliding seat 20 slides out of the housing 10 along with the rack 30 , the frictional force between the top block 11 and the second surface 32 is very small and will not affect the sliding seat 20 swipe action. As the sliding of the rack 30 continues, the contact between the top block 11 and the second surface 32 is released, and the top block 11 no longer affects the sliding action of the sliding seat 20 . It can be understood that the above-mentioned smoothing treatment can be performed on the top block 11 alone or on the second surface 32 alone, as long as the distance between the top block 11 and the second surface 32 is relatively small. The friction force can be generated. Of course, smoothing can also be performed on the top block 11 and the second surface 32 at the same time.

On the other hand, the limiting portion 23 and the rack 30 are elastically connected along the first direction 001 , and the limiting portion 23 will first move when the sliding seat 20 is retracted into the housing 10 . contact with the top block 11 . In order to ensure the smooth passage of the top block 11 and contact with the second surface 32 afterward, so as to release the cooperation between the abutting portion 22 and the groove 34 , it is necessary to place the stopper 23 on the limiting portion 23 . There is an escape structure that allows the top block 11 to pass through. The displacement structure may be a notch or a through hole 231 as shown in FIG. 2 .

Further, in order to facilitate the top block 11 to enter the space between the first surface 21 and the second surface 32 , in an embodiment, the second surface 32 is close to the space along the first direction 001 . One end of the top block 11 is provided with a chamfer 321 . In the process of pushing the rack 20 apart, the top block 11 first contacts the chamfer 321 (see FIG. 8 ), and then slides to the second surface 32 along with the chamfer 231 . The chamfer 321 forms a guide when the top block 11 pushes away the rack 30 .

In the embodiment shown in FIG. 1 , the rack 30 slides relative to the gear 40 along the first direction 001 to drive the sliding seat 20 to slide relative to the housing 10 . However, in other embodiments, the rack 30 does not need to be completely facing the first direction 001 and slide relative to the gear 40, and the sliding of the rack 30 relative to the gear 40 may also be the same as The first direction 001 forms a certain angle, as long as the rack 30 can provide the sliding seat 20 with a sliding component along the first direction 001 . It can be understood that the sliding arrangement of the rack 30 relative to the gear 40 along the first direction 001 is beneficial to the control of the sliding distance of the rack 30 and saves the internal space of the housing 10 .

In order to ensure the sliding angle of the rack 30 relative to the gear 40 , in some embodiments, the number of the abutting portions 22 is set to be multiple. A plurality of the abutting parts 22 are arranged in sequence along the first direction 001; correspondingly, the grooves 34 are also arranged in cooperation with the abutting parts 22, and the number of the grooves 34 corresponds to the number of the abutting parts 22. The number of sections 22 is the same. The arrangement of the grooves 34 is also the same as the arrangement of the abutting portions 22 . In this way, the rack 30 can be prevented from turning over with respect to the sliding angle of the rack 40 due to only one of the abutting portions 22 being pulled by the second elastic member 72 .

Likewise, in some embodiments, the number of the second elastic members 72 is also at least two. The two second elastic members 72 are arranged at intervals along the first direction. That is, the rack 30 is connected to the sliding seat 20 through two spaced apart second elastic members 72 . Through the mutual restraint between the two second elastic members 72, if the rack 30 is turned over relative to the sliding seat 20, one of the second elastic members 72 will be compressed, while the other will be compressed. The second elastic member 72 is stretched. Obviously, the stretched second elastic member 72 will generate more elastic force to pull the rack 30 back to the position before turning over. Such an arrangement is favorable for maintaining the position of the rack 30 .

In one embodiment, the sliding seat 20 is further provided with at least one functional device 80 . Like the camera module 60 , the functional device 80 can extend out of the housing 10 together with the sliding seat 20 . The functional device 80 may be one or more of a camera module, an iris recognition module, a face recognition module, a fingerprint recognition module, a flash, a photosensitive sensor, and an earpiece. The functional device 80 can cooperate with the camera module 60 to achieve functions, such as flash, dual cameras, etc.; or can be independent of the camera module 60 to achieve functions, such as the above-mentioned identification module or earpiece.

FIG. 9 shows an electronic device 200 including the functional component 100 of the present application. The electronic device 200 includes a first panel 201 , and the first panel 201 covers the casing 10 . The sliding seat 20 is correspondingly covered by the first panel 201 . The electronic device 200 of the present application can hide at least part of the functional components 100 behind the first panel 201 without affecting the appearance consistency of the first panel 201 . The appearance consistency of the entire electronic device 200 tends to be complete in all aspects, which improves the look and feel of the electronic device 200 as a whole to the user.

At the same time, since the functional component 100 can achieve a certain protective effect on the camera module 60 after the camera module 60 is extended, the electronic device 200 of the present application has higher reliability and anti-drop capability.

It can be understood that when the first panel 201 is a display screen, the display screen is installed on the casing 10, and the sliding seat 20 is accommodated in the casing 10 at this time. The display area at least partially covers the sliding seat 20 , and because of the need for the arrangement of various functional devices including the camera module on the first panel 201 , the display area of the display screen could not be used for the first panel 201 . When the panel 201 is completely covered, a part of the area on the first panel 201 must be occupied to place these functional devices, thereby compressing the screen ratio of the electronic device 200 . As for the electronic device 200 using the functional component 100 of the present application, because the camera module 60 and the functional device 80 are hidden on the sliding seat 20, they can be extended when needed, thereby avoiding the need for any The camera module 60 and the functional device 80 are disposed on the first panel 201, which destroys the appearance consistency.

It can be understood that, the electronic device 200 can also be provided with a second panel 202 on the side of the functional component 100 opposite to the first panel 201 , that is, the functional component 100 is located between the first panel 201 and the first panel 201 . Between the second panels 202, the second panel 202 also covers at least part of the functional components 100, so that the functional components 100 can be hidden between the first panel 201 and the second panel 202 at the same time, The appearance consistency of the electronic device 200 is further improved.

The electronic device 200 involved in the embodiments of the present application may be any device with communication and storage functions, such as a tablet computer, a mobile phone, an electronic reader, a remote control, a personal computer (PC), a notebook computer, a vehicle-mounted device, Smart devices with network functions such as Internet TV and wearable devices.

The electronic device 200 includes a housing 10 , a sliding seat 20 , a rack 30 , a gear 40 and a motor 50 . The sliding seat 20 is connected with the housing 10 , and the sliding seat 20 can slide relative to the housing 10 along a first direction 001 to extend or retract the housing 10 . The sliding seat 20 is also provided with a camera module 60 . The camera module 60 can be extended or hidden in the casing 10 when the camera module 60 is retracted and slid with the sliding seat 20 . Both the gear 40 and the motor 50 are disposed inside the casing 10 . The motor 50 is fixed inside the casing 10 , and the gear 40 is rotatably disposed inside the casing 10 . The motor 50 is used to drive the gear 40 to rotate. The gear 40 is matched with the tooth profile of the rack 30 , and the rack 30 and the gear 40 mesh with each other. A first elastic member 71 is disposed between the rack 30 and the sliding seat 20 along the first direction 001 . The first elastic member 001 makes the rack 30 abut on the sliding seat 20 along the first direction 001 , and the rack 30 is stationary relative to the sliding seat 20 .

The control method of the electronic device 200 described in this application includes:

101. The electronic device 200 receives an extension signal;
