Fig. 1 is a schematic diagram illustrating a camera module 100 and a housing 201 according to an exemplary embodiment, and fig. 2 is a schematic diagram illustrating another camera module 100 and a housing 201 according to an exemplary embodiment. As shown in fig. 1 and fig. 2, the camera module 100 may include a camera assembly 1 and a driving assembly 2, where the camera assembly 1 and a housing 201 of an electronic device to which the camera module 100 belongs can slide relatively, and specifically, the camera assembly 1 and the driving assembly 2 are matched, so that power output by the driving assembly 2 can be transmitted to the camera assembly 1 to drive the camera assembly 1 to slide relative to the housing 201.

For example, under the driving of the driving assembly 2, the state between the camera assembly 1 and the housing 201 can be switched from the state shown in fig. 1 to the state shown in fig. 2; alternatively, the state between the camera head assembly 1 and the housing 201 is switched from the state shown in fig. 2 to the state shown in fig. 1. In the state shown in fig. 1, the camera module 100 extends out of the housing 201, and is in an extended state, so that external image information can be acquired; in the state shown in fig. 2, the camera module 100 is located inside the housing 201 and is in a storage state.

Specifically, as shown in fig. 1 and 2, the driving assembly 2 may include a driving body 21, a lead screw structure 22, and a transmission structure 23 that transmits power output by the driving body 21 to the lead screw structure 22. The driving body 21 may comprise a power take-off shaft, and the transmission structure 23 has one end connected to the power take-off shaft and the other end connected to the screw structure 22. When the driving body 21 is triggered to switch to the working state, the power output shaft rotates and transmits the motion to the transmission structure 23, the transmission structure 23 further transmits the motion to the lead screw structure 22, the lead screw structure 22 is driven to move, and the camera assembly 1 slides relative to the housing 201 under the action of the lead screw structure 22.

The screw structure 22 and the driving body 21 are arranged in parallel, as shown in fig. 1, the screw structure 22 and the driving body 21 are arranged in a direction indicated by an arrow a, and a motion transmission direction of the transmission structure 23 is parallel to the parallel direction of the driving body 21 and the screw structure 22, that is, the transmission structure 23 can transmit power output by the power output shaft in the direction indicated by the arrow a, so as to realize motion transmission between the parallel driving body 21 and the screw structure 22.

In the technical scheme of the disclosure, the power output by the driving main body 21 can drive the camera assembly 1 to slide after being transmitted by the transmission structure 23 and the lead screw structure 22, so that the position switching between the camera assembly 1 and the shell 201 is realized; moreover, the screw structure 22 can be arranged in parallel with the driving body 21, so that the length of the camera module 100 can be reduced, the structure of the camera module 100 is compact, especially, after the camera module is assembled to an electronic device, the layout mode between the camera module 100 and other electronic components is increased, and the limited layout space in the electronic device is favorably and reasonably utilized.

In one embodiment, as shown in fig. 3, the camera assembly 1 may include a camera body 11 and a camera stand 12. The camera body 11 may include a lens 111, an image sensor 112, and the like, and external image information may be acquired by cooperation of the lens 111, the image sensor 112, and other electronic components of the camera body 11. The camera holder 12 may be used to fix the camera body 11, for example, the camera holder 12 may include a first holder 121 and a second holder 122, the first holder 121 and the second holder 122 cooperate to form an accommodating cavity 123, at least a portion of the camera body 11 is disposed in the accommodating cavity 123, and external image information can be obtained through the accommodating cavity 123. The image sensor 112 may be disposed in the accommodating cavity 123, and the lens 111 may be attached to the first support 121 or the second support 122. Of course, the camera body 11 is described above as an exemplary embodiment, but the camera body 11 may also include other electronic components.

In this embodiment, when the camera head assembly 1 slides under the action of the lead screw structure 22, in order to avoid deviation or inclination of the camera head assembly 1, the sliding direction of the camera head assembly 1 may also be guided in the technical solution of the present disclosure.

In one embodiment, as shown in fig. 3 and 4, the camera bracket 12 may include a guide groove 124 and a first guide post 125, and the first guide post 125 may be fixed on the housing 201 and can pass through the guide groove 124. When the driving assembly 2 works, the screw structure 22 generates an acting force on the camera assembly 1, and the first guide post 123 slides in the guide groove 124, so that the camera support 12 is limited in sliding, and is enabled to move along the setting direction of the guide groove 124, and the camera assembly 1 is prevented from moving randomly in the shell 201.

The length direction of the guide groove 124 is arranged along the moving direction of the camera head assembly 1, and the center line of the camera head assembly 1 is basically overlapped with the center line of the guide groove 124 and the center line of the guide groove 124, so that the moving stability of the camera head support 12 can be improved.

In another embodiment, as shown in fig. 5, the camera module 100 may further include a base 3, and the base 3 may be fixed on the housing 201 so as to be able to switch positions relative to the housing 201 when the camera assembly 1 slides relative to the base 3. Specifically, the base 3 may include the chute 31, and the camera support 12 may include a guide rail 126 engaged with the chute 31, and the movement direction of the camera assembly 1 may be limited by the engagement of the guide rail 126 and the chute 31. Of course, in other embodiments, it is also possible that the base 3 includes the guide rail 126, and the camera bracket 12 includes the sliding groove 31 engaged with the guide rail 126. The number of the matched sliding chutes 31 and the matched guide rails 126 can be one or more, and for example, as shown in fig. 5, two sets of the matched sliding chutes 31 and the matched guide rails 126 can be included.

In the above embodiments, as shown in fig. 6, the camera assembly 1 may further include a flexible circuit board 13, where the flexible circuit board 13 may be used to transmit signals between the camera main body 112 and a controller in the electronic device, so that the electronic device can obtain and display image information according to the signals transmitted by the camera main body 112; similarly, the camera body 112 can switch the switch state according to the signal transmitted by the controller. The camera head assembly 1 may further include a spacer 14, the spacer 14 may be fixed relative to the housing 201, and the guide groove 124 on the camera head bracket 12 and the flexible printed circuit board 13 are located on different sides of the spacer 14, so as to prevent the sliding between the guide groove 124 and the first guide post 125 from rubbing the flexible printed circuit board 13 and affecting the normal transmission of signals.

For example, as shown in fig. 6, in the thickness direction of the electronic device, the spacer 14 may be located above the guide groove 124, and the flexible printed circuit board 13 may be located above the spacer 14, that is, the spacer 14 is located between the flexible printed circuit board 13 and the guide groove 124, so that the flexible printed circuit board 13 is isolated from the guide groove 124.

The spacer 14 and the housing 20 may be directly fixedly connected by a fastener to ensure that the spacer 14 is fixedly disposed when the camera head assembly 1 moves. Alternatively, the spacer 14 may be fixed to the housing 201 by another structure. For example, as also shown in fig. 6, the driving assembly 2 may further include a driving bracket 24 fixed to the housing 201, the spacer 14 may be fixedly connected to the driving bracket 24, and a bottom surface of the driving bracket 24 is located between the flexible printed circuit board 13 and the lead screw structure 22, so as to prevent the flexible printed circuit board 13 from being scratched by the movement of the lead screw structure 22 while the spacer 14 is fixed by the driving bracket 24. Still alternatively, the isolation member 14 may be connected to the housing 201 at one end and connected to the driving bracket 24 at the other end, so as to achieve relative fixation between the isolation member 14 and the housing 201. And may be specifically designed with reference to the structure, which is not intended to be limited by the present disclosure.

In the above embodiments, the camera head assembly 1 can slide relative to the housing 201, and the following description will be given for the cooperation between the lead screw structure 22 and the camera head assembly 1 to explain how the camera head assembly 1 is driven.

As shown in fig. 6 and 7, in an embodiment, the screw structure 22 may include a screw body 221 and a stroke rod 222. The screw body 221 can be matched with the transmission structure 23, so that the transmission structure 23 drives the screw body 221 to rotate. The stroke rod 222 is rotatably connected to the lead screw body 221 and connected to the camera module 1.

Accordingly, when the lead screw body 221 rotates, the stroke pusher 222 moves and acts on the camera module 1 to slide relative to the housing 201, thereby switching the relative positional relationship between the camera module 100 and the housing 201. The lead screw main body 221 may include a rod-shaped structure with threads, and one end of the stroke push rod 222 is connected to the lead screw main body 221 by threads, and the other end may be connected to the camera bracket 12.

In this embodiment, in order to limit the moving direction of the stroke pushing rod 222 and avoid the stroke pushing rod 222 from deviating, the driving assembly 2 may further include a second guide post 25 fixed relative to the housing 201, the second guide post 25 and the lead screw main body 221 are arranged in parallel, one end of the stroke pushing rod 222 is connected with the lead screw main body 221, and the other end is connected with the second guide post 25, so as to limit the moving direction of the stroke pushing rod 222 through the second guide post 25. As shown in fig. 6 and 7, the second guide post 25 may be located on the left side of the screw main body 221, or in some other embodiments, the second guide post 25 may also be located on the right side of the screw main body 221, which may be specifically designed according to needs and layout requirements, and the disclosure is not limited thereto.

The second guide post 25 is slidably connected to the stroke pushing rod 222. For example, as shown in fig. 6 and 7, the stroke push rod 222 may be provided with engaging holes at both ends thereof. Threads can be arranged in a matching hole at one end of the stroke push rod 222, which is connected with the lead screw main body 221, or an internal nut can be assembled, so that the lead screw main body 221 is rotationally connected with the stroke push rod 222, and the rotary motion of the lead screw main body 221 is converted into the translational motion of the stroke push rod 222; the stroke push rod 222 is in transition fit with the second guide post 25 at the end connected with the second guide post 25, so that the situation that the stroke push rod 222 is jammed or jammed between the second guide post 25 is avoided, and the stroke push rod 222 can move horizontally along the setting direction of the second guide post 25.

The fixing of the second guide post 25 relative to the housing 201 may include various forms, and in one embodiment, the second guide post 25 is directly fixed to the housing 201. Alternatively, in another embodiment, the second guide post 25 may be indirectly fixed with respect to the housing 201. For example, as shown in fig. 6 and 7, the driving assembly 2 may further include a driving bracket 24 fixed to the housing 201, and the second guide post 25 is fixedly connected to the driving bracket 24. Of course, in other embodiments, other brackets fixedly connected to the housing 201 may be provided, and the second guide post 25 is fixedly connected to the brackets. Other fixing methods may be provided for the second guide post 25, and are not described in detail herein.

In other embodiments, the sliding groove and the sliding rail may be matched to limit the translation of the stroke pushing rod 222. For example, in an embodiment, the stroke pushing rod 222 may include a sliding groove located on the stroke pushing rod 222 and facing one side of the housing 201, and the housing 201 may be provided with a sliding rail engaged with the sliding groove, so as to limit the movement of the stroke pushing rod 222 relative to the housing 201 through the engagement between the sliding rail and the sliding groove. Alternatively, in another embodiment, a slide rail matched with the slide groove may be formed on the driving bracket 24 to limit the movement of the stroke pushing rod 222. Of course, only the case where the slide groove is formed in the stroke push rod 222 is described here, but it is needless to say that a slide rail may be formed in the stroke push rod 222 and the slide groove may be formed in the housing 201 or the drive bracket 24, and the present disclosure is not limited thereto.

In an embodiment, in order to optimize the force transmission between the camera head assembly 1 and the lead screw main body 221, as shown in fig. 8 and 9, the camera head module 100 may further include an elastic element 4, where one end of the elastic element 4 is fixed to the camera head assembly 1, and the other end of the elastic element 4 is fixed to the lead screw structure 22, and may be specifically connected to the stroke pushing rod 222 included in the lead screw structure 22. Thus, when the driving body 21 operates, the lead screw body 221 rotates, the stroke rod 222 translates, the acting force is transmitted to the camera assembly 1 through the elastic element 4, and the camera assembly 1 is driven to translate. Based on the elastic element 4, when the user manually operates the camera module 100 in the state shown in fig. 1 or the electronic device falls, the acting force generated by the camera module 100 acts on the elastic element 4 and can be partially absorbed by the elastic element 4, so that the acting force is prevented from being directly transmitted to the stroke push rod 222 to cause the stroke push rod 222 to move, and the driving body 21 is enabled to rotate reversely to cause damage.

The elastic element 4 may be fixed to the camera head bracket 12 included in the camera head assembly 1 by welding, and may also be fixed to the stroke pushing rod 222 by welding. The elastic element 4 may include a silicone part, a plastic part, a latex part, or the like, or the elastic element 4 may further include a spring, for example, an extension spring or a compression spring, or may also be another spring for transmitting radial force, which is not described in detail herein.

In each of the above embodiments, force transmission between the screw structure 22 and the driving body 21 needs to be performed through the transmission structure 23, and the structure of the transmission structure 23 will be exemplarily described below.

In an embodiment, also shown in fig. 6, 7, the transmission structure 23 may be located on the same side of the drive body 21 and the lead screw structure 22, e.g., as shown in fig. 7, the transmission structure 23 is located below the drive body 21 and the lead screw structure 22. As shown in fig. 6 and 7, the transmission structure 23 may include a cover 231 and a transmission main body 232, an end surface of the driving bracket 24 of the driving assembly 2 and the cover 231 cooperate to form an accommodating cavity 233, and the accommodating cavity 233 may be used to accommodate the transmission main body 232, so as to isolate the transmission main body 232 from other electronic components, and avoid the influence on other electronic components caused by the rotation of the transmission main body 232.

In the present embodiment, as shown in fig. 7, the transmission body 232 may include a plurality of gears sequentially engaged, one end of the gears being fixedly connected to the power output shaft of the driving body 21, and the other end being fixedly connected to the screw structure 22. Therefore, when the power output shaft rotates, the gear fixedly connected with the power output shaft is driven to rotate, and finally the gear fixedly connected with the lead screw structure 22 is driven to rotate, so that the lead screw structure 22 moves, and the camera assembly 1 is further pushed to move.

For example, as shown in fig. 7, the transmission structure 23 may include a first gear, a second gear and a third gear which are engaged in sequence. Wherein, the first gear is fixedly connected with the power output shaft, the third gear is fixedly connected with the screw rod structure 22, and the second gear is meshed with the first gear and the third gear and is fixed on the end surface of the driving bracket 24. Therefore, when the power output shaft rotates, the first gear rotates, the second gear rotates, and the third gear rotates, and the lead screw structure 22 moves to drive the camera assembly 1 to slide relative to the housing 201.

In the above-described respective embodiments, as shown in fig. 8, the driving body 21 may include the motor 211, and the power output shaft may be provided on the motor 211; or, in order to increase the output torque of the driving body 21 and increase the acting force of the driving body 21 on the screw structure 22, the driving body 21 in the present disclosure may further include a gearbox 212 connected to the motor 211, and the power output shaft is disposed on the gearbox 212.

The motor 211 may include one of a servo motor, a stepping motor, and an asynchronous motor. Taking the example where the motor 211 comprises a stepping motor, the stepping motor may rotate the same angular displacement every time it receives a pulse signal when the stepping motor is in a normal operating state. Therefore, the rotation angle of the stepping motor can be obtained by counting the number of the pulse signals received by the stepping motor, and the displacement of the stroke pushing rod 222 can be further obtained through the transmission ratio in the gear box 212 and the transmission ratio of the transmission structure. Further, the speed and acceleration of the stepping motor can be adjusted by adjusting the frequency of the pulse signal, so that the purpose of adjusting the moving speed of the camera assembly 1 is achieved.

The gearbox 212 may comprise a one-stage gearbox or a multi-stage gearbox. The transmission 212 may include a sun gear, planet gears, planet carrier, ring gear, etc. therein. The sun gear is a driving wheel connected with a rotating shaft of the motor 211, and the planet gear is driven by the sun gear to rotate.

Based on the technical solution of this disclosure, as shown in fig. 9, the camera module 100 may further include a collar 6, the collar 6 may be fixed on the housing 201, and the camera assembly 1 may penetrate through the collar 6 and reciprocate relative to the collar 6. Since the camera head assembly 1 can reciprocate relative to the collar 6, there is usually a small gap between the inner wall of the collar 6 and the camera head assembly 1, so as to avoid external liquid from entering the interior of the electronic device through the gap:

in an embodiment, the camera module 100 may further include a first waterproof member 7, where the first waterproof member 7 is located between an inner wall of the collar 6 and the camera assembly 1, and interferes with the collar 6 or the camera assembly 1 to fill a gap between a surface of the camera assembly 1 and the inner wall of the collar 6, so as to prevent external liquid from entering the electronic device through the gap between the collar 6 and the camera assembly 1 and affecting normal operation of the camera module 100 and other electronic components.

Wherein the interference between the first waterproof member 7 and the collar 6 or the camera head assembly 7 may be represented as: when the first waterproof member 6 is positioned between the camera head assembly 1 and the collar 6, the first waterproof member 7 is deformed by the camera head assembly 1 or the collar 6 because the thickness thereof is larger than the gap between the collar 6 and the camera head assembly 1.

Further, in an embodiment, the first waterproof member 7 may be a surface formed on the camera head assembly 1 facing the inner wall of the collar 6 by injection molding, so that when the camera head assembly 1 and the collar 6 are assembled, the first waterproof member 7 may interfere with the inner wall of the collar 6 to achieve a waterproof effect.

In another embodiment, as shown in fig. 8, the first waterproof member 7 may be fixed to the collar 6 so that the first waterproof member 7 is deformed during assembly of the camera head assembly 1 with the collar 6 to thereby function as a waterproof. Wherein, the first waterproof part 7 can be directly formed on the inner wall of the lantern ring 6 by an injection molding process; alternatively, the collar 6 may include a first groove (not shown) formed by an inner wall of the collar 6 being recessed inward, and the first waterproof member 7 may be disposed in the first groove and protrude from an inner wall surface of the collar 6, so that the first waterproof member 7 is deformed in interaction with the camera head assembly 1 when the camera head assembly 1 is assembled.

Wherein the gap between the inner wall of the collar 6 and the camera assembly 1 may be between 0.1-0.2mm, then the height of the first flashing 7 protruding over the surface of the inner wall of the collar 6 may be within 0.15-0.5mm, so that the first flashing 7 can have an interference with the camera assembly 1 of 0.05-0.3 mm. For example, it may be interference 0.1mm, 0.15mm, 0.18mm, 0.2mm, 0.25mm, etc.

In this embodiment, the collar may comprise one or more first grooves which, when the collar comprises a plurality of first grooves, are capable of encircling the camera head assembly at least once around, thereby providing waterproofing at various locations around the circumference of the camera head assembly. For example, the first plurality of recesses may include a full circle structure that surrounds the camera head assembly, or the first plurality of recesses may include a plurality of non-full circle structures that fit at least one full circle around the camera head assembly.

In each of the above embodiments, as shown in fig. 8, the camera module 100 may further include a second waterproof member 8, where the second waterproof member 8 is located between an end surface of the collar 6 and a sidewall of the housing 201, and is capable of interfering with the collar 6 or the housing 201 to fill a gap between the collar 6 and the housing, so as to prevent external liquid from entering the electronic device from between the housing 201 and the sidewall of the collar 6, thereby enhancing the waterproof performance of the electronic device. Wherein the interference between the second flashing 8 and the collar 6 and the housing 201 may be represented by: when the second flashing 8 is located between the housing 201 and the collar 6, deformation occurs under the influence of the camera head assembly 1 or the collar 6, since the thickness of the second flashing 8 is greater than the gap between the collar 6 and the housing.

For example, as also shown in the figures, the collar 6 may comprise a second groove (not shown in the figures) formed by an inward recess of an end face of the collar 6 facing the side wall of the casing 201, and the second waterproof member 8 may be pre-assembled in the second groove and have a portion protruding beyond the end face of the collar 6, so that subsequently, when the collar 6 and the casing 201 are assembled, the second waterproof member 8 is deformed by the casing 201 to interfere with the casing 201, thereby achieving waterproofing.

In the present embodiment, the height of the second waterproof member 8 protruding from the end face of the collar 6 is in the range of 0.05-0.4mm, and may be, for example, 0.1mm, 0.15mm, 0.18mm, 0.23mm, 0.26mm, 0.3mm, 0.35mm, which is not limited in the present disclosure. More specifically, the height of the second flashing 8 protruding over the end surface of the collar 6 may be in the range of 0.1-0.15 mm.

Of course, in the embodiment shown in fig. 9, the camera module 100 may include both the first waterproof member 7 and the second waterproof member 8. It is understood that in other embodiments, only the first waterproof member 7 or the second waterproof member 8 may be included, and the description is omitted.

Based on the camera module 100 shown in fig. 1-9, it can be configured in the electronic device 200 shown in fig. 10, and is fixedly connected with the housing 201 of the electronic device 200. The housing 201 may include an opening through which a portion of the camera assembly 1 included in the camera module 100 can protrude out of the housing 201; or retract into the casing 201, so as to avoid the camera assembly 1 from occupying the display area of the screen on the electronic device 200, which is beneficial to improving the screen occupation ratio of the electronic device 200.
