The following describes in detail a camera module and an electronic device provided in the embodiments of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in fig. 1 to 9, an embodiment of the present application provides a camera module, which includes a base 110, a photosensitive chip 120, a first barrel 140, a first lens 150, and a driving mechanism.
The photosensitive chip 120 is disposed on the base 110, and the base 110 may further include other devices of the camera module besides the photosensitive chip 120. The first barrel 140 has a first lens 150, and the first lens 150 is disposed opposite to the photo sensor chip 120. The first lens 150 and the photosensitive chip 120 may be disposed along an optical axis direction of the camera module. The photo sensor chip 120 may be used to receive the light incident from the first lens 150 and finally convert the light signal into a digital image signal, thereby obtaining an image. The first lens barrel 140 is sleeved on the base 110, the first lens barrel 140 is connected with the base 110 through the first matching protrusion 131 and the first spiral guide groove 111, and the first spiral guide groove 111 is a linear spiral groove. The straight type spiral groove herein refers to a spiral groove having no inflection point, and thus, the first fitting projection 131 can smoothly slide in the first spiral guide groove 111.
The driving mechanism is connected to the first barrel 140, and the driving mechanism drives the first barrel 140 to move along a first direction under the cooperation of the first engaging protrusion 131 and the first spiral guide groove 111, where the first direction is a direction close to or away from the photosensitive chip 120. That is to say, according to the requirement of image capturing, under the driving action of the driving mechanism, the first lens barrel 140 can drive the first lens 150 to move in the direction close to or away from the photosensitive chip 120, so as to implement the zoom function of the camera module. Since the first engaging protrusion 131 can smoothly slide in the first spiral guiding groove 111, the first barrel 140 can drive the first lens 150 to smoothly zoom.
In the embodiment of the present application, when the camera module needs to zoom, the driving mechanism drives the first barrel 140 to move in a direction close to or away from the photo chip 120 under the cooperation of the first engaging protrusion 131 and the first spiral guiding groove 111, so as to drive the first lens 150 to move away from or close to the photo chip 120. Because the first spiral guide groove 111 is a linear guide groove, the first spiral guide groove 111 does not have an obvious inflection point, and therefore, the first lens barrel 140 is not easily jammed at the inflection point when moving, so that the first lens barrel can move more smoothly, and the zoom effect of the camera module is improved.
In the above embodiment, the driving mechanism can directly drive the first barrel 140 to move in a direction approaching or departing from the photo sensor chip 120 under the cooperation of the first engaging protrusion 131 and the first spiral guide groove 111, at this time, the distance variation range between the first lens 150 and the photo sensor chip 120 depends on the movement amount of the first barrel 140, and since the movement amount of the first barrel 140 is limited, the distance variation range between the first lens 150 and the photo sensor chip 120 is limited, which is not favorable for greatly improving the zoom effect of the camera module. Therefore, the camera module may further include a driving bracket 130, the driving bracket 130 is sleeved on the base 110, one of the base 110 and the driving bracket 130 is provided with a first engaging protrusion 131, the other is provided with a first spiral guiding groove 111, and the driving bracket 130 can rotate and move along with the engagement of the first engaging protrusion 131 and the first spiral guiding groove 111. The first lens barrel 140 is sleeved on the driving support 130, one of the first lens barrel 140 and the driving support 130 is provided with a second matching protrusion 141, the other one is provided with a second spiral guide groove 132, the spiral direction of the first spiral guide groove 111 is opposite to the spiral direction of the second spiral guide groove 132, the first lens barrel 140 can move along with the matching of the second matching protrusion 141 and the second spiral guide groove 132, and the second spiral guide groove 132 is a linear spiral groove. The straight type spiral groove herein refers to a spiral groove having no inflection point, and thus, the second fitting projection 141 can smoothly slide in the second spiral guide groove 132. The driving mechanism is connected to the driving bracket 130, and the driving mechanism drives the driving bracket 130 to rotate.
When the camera module needs zooming, the driving mechanism may be controlled to drive the driving bracket 130 to rotate, under the cooperation of the first engaging protrusion 131 and the first spiral guiding groove 111, when the driving bracket 130 rotates along the second direction, the driving bracket 130 may gradually get away from the photosensitive chip 120, that is, the driving bracket 130 gradually protrudes out of the base 110, and when the driving bracket 130 rotates along the third direction, the driving bracket 130 may gradually get close to the photosensitive chip 120, that is, the driving bracket 130 gradually retracts into the base 110, where the third direction is opposite to the second direction. Meanwhile, since the spiral direction of the first spiral guide groove 111 is opposite to the spiral direction of the second spiral guide groove 132, in the case that the driving bracket 130 rotates and moves, and under the cooperation of the second engaging protrusion 141 and the second spiral guide groove 132, when the driving bracket 130 rotates in the second direction, the first barrel 140 may gradually be away from the photosensitive chip 120 and gradually extend out of the driving bracket 130, and when the driving bracket 130 rotates in the third direction, the first barrel 140 may gradually approach the photosensitive chip 120 and gradually retract into the driving bracket 130. That is, in the case where the driving bracket 130 is rotated in the second direction, the driving bracket 130 and the first barrel 140 are simultaneously away from the photosensitive chip 120; in the case where the driving bracket 130 is rotated in the third direction, the driving bracket 130 and the first barrel 140 simultaneously approach the photosensitive chip 120. Through the above manner, the driving bracket 130 and the first lens barrel 140 can both move relative to the base 110, so that the distance between the first lens 150 and the photosensitive chip 120 can be changed in a larger range, and thus, the camera module can adapt to more shooting scenes, and therefore, the zooming effect of the camera module is better. Moreover, since the first spiral guide groove 111 and the second spiral guide groove 132 are both linear spiral grooves, both the driving bracket 130 and the first barrel 140 can move smoothly, and thus the zoom stability of the camera module can be improved. In addition, in the case where the driving bracket 130 and the first barrel 140 are simultaneously close to the photosensitive chip 120, the driving bracket 130 may be gradually retracted into the base 110, and the first barrel 140 may be gradually retracted into the driving bracket 130, and thus, in the case where the camera module is in a non-photographing state, the volume of the camera module may be small.
In addition, the camera module may further include a second lens barrel 250, the second lens barrel 250 is covered on the driving bracket 130, and the second lens barrel 250 may be connected to the driving bracket 130 by bonding, riveting, screwing, or the like. The second barrel 250 may protect the driving bracket 130 to prevent an object in the external environment from colliding against the driving bracket 130.
In an alternative embodiment, in order to further improve the zooming effect of the camera module, the camera module may further include a zooming guide frame 160, the zooming guide frame 160 is sleeved on the driving bracket 130, and the zooming guide frame 160 is connected to the driving bracket 130 through a third matching protrusion 162a and a third spiral guide groove 161 a. The zoom guide 160 is provided with a second lens 170, and the second lens 170 can move along with the cooperation between the third engaging protrusion 162a and the third spiral guide groove 161 a. In the case that the driving mechanism drives the driving bracket 130 to rotate, the driving bracket 130 may drive the zooming guide frame 160 to move, and at the same time, under the cooperation of the third engaging protrusion 162a and the third spiral guide groove 161a, the second lens 170 may be close to the photosensitive chip 120 or far from the photosensitive chip 120. In this embodiment, through the cooperation of the second lens 170 and the first lens 150 that set up on the guide frame 160 zooms, can realize the function of zooming in succession of camera module to can make the process of zooming of camera module link up more through the guide frame 160 that zooms, thereby make the focus of camera module more diversified, with this use of satisfying the camera module under more scenes, thereby can further improve the effect of zooming of camera module.
