Background

Along with the rapid development of electronic equipment, a telescopic camera module becomes the mainstream of development, the telescopic camera adopted by the camera module of the electronic equipment is mainly driven by a driving device, and the design of the driving device determines the accuracy and reliability of the movement of the telescopic camera.

The current driving device generally comprises a motor and a gear, wherein the motor is connected with the lens barrels through the gear, a matching bulge can be arranged on one lens barrel for realizing the movement of the lenses, a chute is arranged on the other lens barrel, the matching bulge and the chute can be used as a transmission structure, and when one lens barrel rotates, the matching bulge is in sliding fit with the chute, so that the relative movement between the two lens barrels is realized, and the movement of the lenses is finally realized.

But when the telescopic camera is in an extending state, and the electronic equipment falls, the transmission structure inside the telescopic camera can receive a larger impact load, namely, larger impact is generated between the matching bulge and the sliding groove, and the matching bulge and the sliding groove are easy to fail, so that the reliability of the camera module is poor.

It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The camera module disclosed in the embodiments of the present application is described in detail below with reference to the accompanying drawings by means of specific embodiments and application scenarios thereof.

Referring to fig. 1 to 11, the present application discloses a camera module, which includes a base 100, a photosensitive chip 200, a first lens barrel 300, a first lens 700, a driving mechanism 400 and a support 500.

The base 100 may be used as a base member of the camera module, and provides a mounting base for other components of the camera module, for example, the photosensitive chip 200, where the photosensitive chip 200 is disposed on the base 100, and the photosensitive chip 200 is one of main components of the camera module for realizing photographing. The first lens barrel 300 is telescopically disposed on the camera module to achieve the zoom purpose of the camera module and further meet different shooting requirements, specifically, the first lens barrel 300 is sleeved on the base 100, and the first lens barrel 300 is provided with a first lens 700, i.e. when the first lens barrel 300 is telescopic relative to the base 100, the first lens barrel 300 can drive the first lens 700 to be telescopic relative to the base 100. The number of the first lenses 700 may be one or more, and the camera module may further include a second lens, which may be stationary with respect to the photosensitive chip 200 or may be telescopic with respect to the photosensitive chip 200, so as to further optimize the zooming effect.

The above-mentioned telescopic process can be implemented by the driving mechanism 400, specifically, the driving mechanism 400 is connected with the first lens barrel 300, the driving mechanism 400 can drive the first lens barrel 300 to move along a first direction, the first direction is a direction approaching or separating from the photosensitive chip 200, and when the driving mechanism 400 drives the first lens barrel 300 to move along a direction separating from or approaching the photosensitive chip 200, the zoom shooting requirement of the camera module can be implemented.

The support member 500 has a supporting function, specifically, the support member 500 is movably disposed on the base 100, the support member 500 can move between a first position and a second position, and in the case that the support member 500 is located at the first position, the support member 500 can avoid the first lens barrel 300, so that the first lens barrel 300 can move along the first direction, that is, at this time, the support member 500 does not affect the expansion and contraction of the first lens barrel 300 relative to the base 100; in the case that the support 500 is located at the second position, the first lens barrel 300 extends relative to the base 100, such that at least a portion of the support 500 is located between the first lens barrel 300 and the photosensitive chip 200 to support the first lens barrel 300, i.e. where the front projection of the first lens barrel 300 overlaps with the front projection of the support 500 in the arrangement direction of the first lens 700 and the photosensitive chip 200.

At this time, if the electronic device provided with the camera module falls, this causes the first barrel 300 to collide with the object, so that the first barrel 300 generates a force towards the photosensitive chip 200, and since the support member 500 can support the first barrel 300, the force can act on the support member 500 through the first barrel 300 to prevent the first barrel 300 from acting on the driving mechanism 400, i.e. the support member 500 can share a part of the energy generated by the impact of the first barrel 300, so as to reduce the collision energy received by the transmission structure of the driving mechanism 400, i.e. reduce the collision energy received by the transmission mechanism 420, the first engaging protrusion 610 and the second engaging protrusion 310, which will be described later.

In this embodiment, since the first lens 700 is disposed on the first lens barrel 300, the driving mechanism 400 can simultaneously drive the first lens barrel 300 and the first lens 700 to move in a direction approaching or separating from the photosensitive chip 200, the support member 500 can move on the base 100 between the first position and the second position, and in the case that the support member 500 is located at the first position, the support member 500 can avoid the first lens barrel 300, so that the first lens barrel 300 can move in a direction approaching or separating from the photosensitive chip 200; in the case where the support 500 is located at the second position, the first barrel 300 is extended with respect to the base 100, and at this time, at least part of the support 500 is located between the first barrel 300 and the photosensitive chip 200 to support the first barrel 300. Therefore, when the electronic device falls, the first lens barrel 300 is impacted, the first lens barrel 300 can transmit the impact to the supporting member 500, that is, the supporting member 500 can share a part of energy generated by the impact, so that the first lens barrel 300 and the transmission structure inside the camera module are less damaged, and the reliability of the camera module can be improved.

Optionally, the base 100 includes a fixing sleeve 110, the first lens barrel 300 is sleeved in the fixing sleeve 110, the supporting member 500 is telescopically disposed on an inner wall of the fixing sleeve 110, so that the supporting member 500 can move between a first position and a second position, and a telescopic direction of the supporting member 500 can be perpendicular to the first direction, which makes the supporting member 500 support the first lens barrel 300 when the first lens barrel 300 extends out relative to the base 100, but since the supporting member 500 is disposed on the inner wall of the fixing sleeve 110, a space for installing the supporting member 500 needs to be reserved between the fixing sleeve 110 and the first lens barrel 300, and thus a space occupied by the fixing sleeve 110, the supporting member 500 and the first lens barrel 300 is increased, which is disadvantageous for other components.

Therefore, in another embodiment, the fixing sleeve 110 is provided with the avoiding hole 111 penetrating the fixing sleeve 110, that is, the fixing sleeve 110 is provided with the through hole facing the first lens barrel 300, at least part of the supporting member 500 is disposed in the avoiding hole 111, and the supporting member 500 can move between the first position and the second position along the penetrating direction of the avoiding hole 111, at this time, since at least part of the supporting member 500 is disposed in the avoiding hole 111, the space between the fixing sleeve 110 and the first lens barrel 300, which is required to be additionally reserved for setting the supporting member 500, is smaller, and even the space for setting the supporting member 500 is not required to be reserved, so that the space of the camera module occupied by the fixing sleeve 110, the supporting member 500 and the first lens barrel 300 is smaller, which is further beneficial to the installation and setting of other components, and meanwhile, the supporting member 500 can be set long enough to promote the supporting effect on the first lens barrel 300.

Alternatively, the driving mechanism 400 may include a driving disc 430 and at least two driving sources 410, wherein one driving source 410 is connected to the driving disc 430, the driving disc 430 is disposed around the fixed sleeve 110, and the supporting member 500 is connected to the driving disc 430, that is, the driving source 410 is capable of driving the driving disc 430 to move, so that the driving disc 430 is capable of driving the supporting member 500 to move, and in particular, the driving disc 430 is capable of driving the supporting member 500 to move between the first position and the second position; the other driving source 410 is connected to the first barrel 300 to drive the first barrel 300 to move, and specifically, the first barrel 300 can move in the first direction under the driving of the driving source 410.

However, such a manner of arranging the at least two driving sources 410 may result in an increase in the overall size of the camera module, and it is not easy to ensure that the at least two driving sources 410 simultaneously drive the first lens barrel 300 and the driving disc 430 respectively, so that the supporting member 500 may not timely and accurately support the first lens barrel 300.

To avoid the above-mentioned problem, in another embodiment, the driving mechanism 400 includes a transmission mechanism 420 and a driving source 410, and the driving source 410 is connected to the driving plate 430 and the first barrel 300 through the transmission mechanism 420, respectively, i.e., the driving source 410 can simultaneously drive the first barrel 300 and the driving plate 430 to move through the transmission mechanism 420, thereby enabling the supporting member 500 and the first barrel 300 to simultaneously move. Therefore, in this arrangement, the same driving source 410 drives the supporting member 500 and the first lens barrel 300 to move simultaneously, so that the problem of larger overall size of the camera module can be avoided, and the supporting member 500 can be ensured to support the first lens barrel 300 timely and accurately. Alternatively, the driving source 410 may be a motor or the like having a driving function.

Alternatively, the transmission mechanism 420 may be a gear transmission mechanism, that is, the transmission mechanism 420 includes a first gear 421, a second gear 422 and a third gear 423, a worm 411 is disposed on an output shaft of the driving source 410, the worm 411 is meshed with the first gear 421, the first gear 421 is meshed with the second gear 422 and the third gear 423, the second gear 422 drives the first lens barrel 300 to move along a direction approaching or separating from the photosensitive chip 200, and the third gear 423 is meshed with the first driving tooth 432 of the driving disc 430 to drive the driving disc 430 to move, so that the driving disc 430 drives the supporting member 500 to move between the first position and the second position.

In one embodiment, the support member 500 may be rotatably coupled to the drive plate 430, i.e., the bypass aperture 111 may be configured to be relatively large during rotation of the drive plate 430 by the drive source 410, such that the support member 500 may move relative to the bypass aperture 111, and the drive plate 430 may apply a force to the support member 500, i.e., push or pull the support member 500, to move the support member 500 relative to the bypass aperture 111 between the first position and the second position.

In another embodiment, the supporting member 500 is slidably engaged with the driving disc 430, specifically, the supporting member 500 includes a first supporting portion 510 and a first protruding portion 520, the first supporting portion 510 is connected to the first protruding portion 520, at least a portion of the first supporting portion 510 is disposed in the avoidance hole 111, the first protruding portion 520 is slidably engaged with the sliding groove 431, and the driving disc 430 drives the first protruding portion 520 to slide in the sliding groove 431, so that the first protruding portion 520 drives the first supporting portion 510 to move in the avoidance hole 111. In this arrangement, the first protruding portion 520 is slidably engaged with the sliding groove 431, so that the contact area between the driving disc 430 and the supporting member 500 is larger, and the driving disc 430 can more stably and reliably drive the supporting member 500 to move in the avoiding hole 111. Meanwhile, when the sliding fit is adopted, the supporting member 500 can move between the first position and the second position relative to the avoiding hole 111, and the avoiding hole 111 can be smaller, so that the structural strength of the fixing sleeve 110 is improved, and meanwhile, guiding is provided for the movement of the supporting member 500, so that the supporting member 500 moves more stably.

Alternatively, the shape of the chute 431 may be linear, i.e. the distance between the different positions of the chute 431 and the center line of the first lens 700 is uniformly and continuously changed, since the driving source 410 can drive the supporting member 500 and the first lens barrel 300 to move simultaneously, i.e. the starting movement time point and the stopping movement time point of the supporting member 500 and the first lens barrel 300 are consistent, but since the supporting member 500 needs to move in the linear chute 431 for a long time to move in place, once the camera module falls during this movement, the supporting member 500 cannot support the first lens barrel 300 at this time, i.e. the supporting member 500 cannot play a supporting role at this time.

To enable the support 500 to function faster, in another embodiment, the shape of the chute 431 is a bent shape, specifically, the chute 431 includes a first slot section 4311 and a second slot section 4312 that are in communication, the first slot section 4311 is bent relative to the second slot section 4312, and when the first protrusion 520 is matched with the first slot section 4311, the support 500 moves in a second direction, which may be a direction approaching or moving away from the center line of the first lens 700, that is, when the first protrusion 520 slides in the first slot section 4311, the support 500 may approach or move away from the center line of the first lens 700. Alternatively, the first groove section 4311 herein may be a linear groove section, the distance between the different positions of which and the center line of the first lens 700 is uniformly and continuously varied.

In the case that the first protrusion 520 is matched with the second groove section 4312, at least part of the supporting member 500 is located between the first lens barrel 300 and the photosensitive chip 200 to support the first lens barrel 300, that is, the first protrusion 520, once being matched with the second groove section 4312, can already make at least part of the supporting member 500 support the first lens barrel 300 to make the supporting member 500 exert a supporting function, so that the supporting member 500 can be moved in place more quickly to support the first lens barrel 300. Alternatively, the second groove section 4312 may be an arc-shaped groove section, the center of the circumference of which coincides with the rotation center of the driving disk 430, and the supporting member 500 is not moved but is maintained in a position to support the first barrel 300 in the case that the first protrusion 520 is engaged with the second groove section 4312.

Alternatively, the camera module may achieve the zoom photographing purpose only by the extension and retraction of the first lens barrel 300, and the zoom range of the camera module is limited all the time. Therefore, in order to expand the zoom range, in another embodiment, the camera module further includes a second lens barrel 600, the first lens barrel 300 is sleeved on the second lens barrel 600, one of the second lens barrel 600 and the fixing sleeve 110 is provided with a first fitting protrusion 610, the other is provided with a first spiral guiding groove 114, optionally, the second lens barrel 600 is provided with a first fitting protrusion 610, the fixing sleeve 110 is provided with a first spiral guiding groove 114, and the first fitting protrusion 610 can move along the first spiral guiding groove 114.

Since the driving mechanism 400 is connected to the second lens barrel 600 through the transmission mechanism 420, the driving mechanism 400 may drive the transmission mechanism 420 to drive the second lens barrel 600 to move, that is, the second lens barrel 600 may be driven by the driving force provided by the driving mechanism 400, specifically, the second lens barrel 600 is provided with the second driving teeth 640, the second driving teeth 640 are meshed with the second gear 422 of the transmission mechanism 420, and the second gear 422 drives the second lens barrel 600 to rotate through the second driving teeth 640, so that the first engaging protrusion 610 of the second lens barrel 600 may slide in the first spiral guiding groove 114, that is, the second lens barrel 600 may move along the first direction under the engagement of the first engaging protrusion 610 and the first spiral guiding groove 114, and the first direction may be the direction approaching or separating from the photosensitive chip 200.

Under the condition that the supporting member 500 is located at the second position, the first lens barrel 300 and the second lens barrel 600 extend relative to the base 100, that is, the first lens barrel 300 and the second lens barrel 600 are both far away from the photosensitive chip 200, so as to enlarge the zoom range of the camera module, at this moment, at least part of the supporting member 500 is located between the second lens barrel 600 and the photosensitive chip 200, so as to simultaneously support the first lens barrel 300 and the second lens barrel 600, so that when the electronic device falls, the first fitting protrusion 610 and the first spiral guide groove 114 are subjected to larger impact force, and thus a failure phenomenon occurs.

In one embodiment, in order to drive the first lens barrel 300 to retract relative to the second lens barrel 600, a driving magnet may be disposed on the second lens barrel 600, a driving coil is disposed on the first lens barrel 300, and after the driving coil is energized, the driving magnet is used to drive the first lens barrel 300 to retract relative to the second lens barrel 600.

In another embodiment, one of the second barrel 600 and the first barrel 300 is provided with the second fitting protrusion 310, and the other is provided with the second spiral guide groove 620, and optionally the first barrel 300 is provided with the second fitting protrusion 310, and the second barrel 600 is provided with the second spiral guide groove 620. The second engaging protrusion 310 engages with the second spiral guide groove 620 so that the second barrel 600 may drive the first barrel 300 to move in a first direction, which may be a direction approaching or separating from the photosensitive chip 200. The first lens barrel 300 is retracted relative to the second lens barrel 600 by the guiding and matching manner of the second matching protrusion 310 and the second spiral guiding groove 620, and has better retraction stability and reliability.

Optionally, the camera module further includes a guiding cylinder 800, the guiding cylinder 800 is sleeved in the second lens barrel 600, and the guiding cylinder 800 is fixed relative to the second lens barrel 600 in the first direction, that is, the second lens barrel 600 may drive the guiding cylinder 800 to move along the direction approaching or departing from the photosensitive chip 200, the guiding cylinder 800 is provided with a first sliding groove 810, the extending direction of the first sliding groove 810 is parallel to the first direction, the second engaging protrusion 310 may be fixedly connected with the lens barrel body of the first lens barrel 300, one end of the second engaging protrusion 310 is slidably engaged with the second spiral guiding groove 620, the other end is slidably engaged with the first sliding groove 810, and when the second lens barrel 600 moves along the direction approaching or departing from the photosensitive chip 200, the second engaging protrusion 310 slides in the second spiral guiding groove 620 and the first sliding groove 810 to drive the first lens barrel 300 to stretch relative to the second lens barrel 600.

Optionally, the guide cylinder 800 is slidably disposed in the fixed sleeve 110, specifically, the guide cylinder 800 is provided with a second protruding portion 820, the fixed sleeve 110 is further provided with a third sliding groove 115, and an extending direction of the third sliding groove 115 is parallel to the first direction, and when the second lens barrel 600 drives the guide cylinder 800 to stretch relative to the base 100, the second protruding portion 820 is slidably engaged with the third sliding groove 115, so that the guide cylinder 800 moves along the extending direction of the third sliding groove 115.

Optionally, the second lens barrel 600 may drive the guide cylinder 800 to move along the first direction, specifically, the guide cylinder 800 is provided with a third spiral guide groove 830, the second lens barrel 600 is provided with a second sliding groove 650, the camera module further includes a driving post, the extending direction of the second sliding groove 650 is parallel to the first direction, one end of the driving post is slidably disposed in the third spiral guide groove 830, and the other end of the driving post is slidably disposed in the second sliding groove 650, so that when the second lens barrel 600 moves, the second lens barrel 600 may drive the guide cylinder 800 to move along the first direction, and at this time, the supporting member 500 supports the second lens barrel 600 and the first lens barrel 300 by supporting the guide cylinder 800.

Optionally, to prevent the driving post from sliding out of the second sliding groove 650, a blocking portion 630 is further provided on the second lens barrel 600, and the blocking portion 630 can prevent the driving post from sliding out of the second sliding groove 650, so as to ensure the stability of the second lens barrel 600 driving the guide barrel 800 to move.

Optionally, a portion of the support member 500 passes through the relief hole 111 and enters the interior of the fixing sleeve 110, and another portion of the support member 500 may be exposed outside the fixing sleeve 110 when the support effect is achieved, i.e., at least a portion of the support member 500 is at risk of exposure.

To avoid the above risk to protect the support member 500, in another embodiment, the fixing sleeve 110 includes a sleeve body 112 and a mounting portion 113, the mounting portion 113 protrudes from an outer circumferential surface of the sleeve body 112, and the mounting portion 113 is in communication with the avoidance hole 111, at least part of the support member 500 is disposed on the mounting portion 113, in this arrangement, the mounting portion 113 can protect the support member 500, and at the same time, since the mounting portion 113 protrudes from the sleeve body 112, the distance of the support member 500 movable in the avoidance hole 111 is longer, and therefore, the mounting portion 113 can also perform a certain guiding function, which enables the support member 500 to move between the first position and the second position more stably.

Alternatively, the number of the supporting members 500 may be one, but the supporting force provided by one supporting member 500 is small. Therefore, in another embodiment, the number of the supporting members 500 is at least two, and each supporting member 500 is uniformly and alternately arranged in the direction surrounding the center line of the first lens 700, so that the first lens barrel 300 and the second lens barrel 600 can be subjected to a relatively uniform supporting force, and the supporting capability of the plurality of supporting members 500 on the first lens barrel 300 and the second lens barrel 600 is further improved, so that the protection effect on the transmission mechanism 420, the first matching protrusion 610, the first spiral guiding groove 114, the second matching protrusion 310 and the second spiral guiding groove 620 can be improved, the mechanical reliability of the whole camera module is further effectively improved, the service life of the whole camera module is prolonged, and the user experience is improved.

Meanwhile, the support member 500 is arranged on the fixing sleeve 110, so that the compactness of the internal structure of the camera module is ensured while the design space of the camera module is utilized.
