[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described clearly and completely with reference to specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0027] The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] Please refer to Figure 1-Figure 4 The embodiment of the present invention discloses a camera module, and the disclosed camera module can be applied to electronic equipment. The disclosed camera module includes a module housing 100, a driving mechanism 200, and a mechanical anti-shake camera assembly 300.
[0029] The module housing 100 is a basic component of the camera module, and the module housing 100 can provide an installation basis for other components of the camera module. In the embodiment of the present invention, the module housing 100 has a housing inner cavity 110, the housing inner cavity 110 has an opening, and the opening serves as a retreat. The mechanical anti-shake camera assembly 300 is at least partially disposed in the inner cavity 110 of the housing. The mechanical anti-shake camera assembly 300 includes a camera 310 that can realize image shooting through the opening.
[0030] In the embodiment of the present invention, the module housing 100 is a structure that can rotate, and the mechanical anti-shake camera assembly 300 can rotate with the module housing 100. Under normal circumstances, the electronic device disclosed in the embodiment of the present invention may include a device housing 400, and the module housing 100 is rotatably disposed on the device housing 400, thereby achieving rotation. In a specific embodiment, the module housing 100 can be rotatably disposed on the equipment housing 400 through the bearing 600.
[0031] The drive mechanism 200 is connected to the module housing 100, and the drive mechanism 200 can drive the module housing 100 to rotate. In essence, the drive mechanism 200 can drive the module housing 100 so that the module housing 100 and the mechanical anti-shake camera assembly 300 Rotate together.
[0032] The mechanical anti-shake camera assembly 300 includes a camera 310. In a specific working process, when the entire camera module is tilted due to jitter, the camera 310 can be rotated to compensate for the tilt, thereby achieving anti-shake. Since the camera 310 can rotate, the camera 310 has multiple positions. When the camera 310 is in the first position, the lens axis of the camera 310 coincides with or parallel to the rotation axis of the module housing 100. When the camera 310 is in the first position, the camera module does not tilt, and the camera 310 does not tilt.
[0033] When the camera 310 is in the second position, there is an angle between the lens axis of the camera 310 and the rotation axis of the module housing 100, and in this case, the driving mechanism 200 drives the module housing 100 to rotate. Specifically, the included angle between the lens axis of the camera 310 and the rotation axis of the module housing 100 may be an acute angle. When the camera 310 is in the second position, the camera 310 can be in a tilted state. In this case, the drive module housing 100 can realize the camera 310 to capture images in a larger field of view.
[0034] The camera module disclosed in the embodiment of the present invention is based on the mechanical anti-shake camera assembly 300, and makes full use of the structural feature that the camera 310 of the mechanical anti-shake camera assembly 300 can rotate. The drive mechanism 200 drives the module housing 100 to rotate, thereby driving the The camera 310 in the tilted state rotates again, so that the camera 310 obtains a larger shooting field of view. The camera module does not need to be equipped with a special driving mechanism for driving the camera to rotate in multiple directions. Obviously, the electronic device disclosed in the embodiment of the present invention has a simpler structure and a lower manufacturing cost.
[0035] In the embodiment of the present invention, there may be multiple types of the mechanical anti-shake camera assembly 300. Please refer again image 3 with Figure 4 In a specific implementation, the mechanical anti-shake camera assembly 300 may further include a first bracket 320, the first bracket 320 is at least partially disposed in the housing cavity 110, the camera 310 is at least partially disposed in the housing cavity 110, and the camera 310 can perform shooting through the opening of the housing inner cavity 110.
[0036] In the embodiment of the present invention, the camera 310 and the first bracket 320 are hinged through the first hinge axis 330, and the camera 310 can rotate around the first hinge axis 330. The first bracket 320 is hinged with the module housing 100 through a second hinge axis, and the first bracket 320 rotates around the second hinge axis. The axis of the first hinge axis 330 and the axis of the second hinge axis intersect or are in different planes, that is, the direction in which the camera 310 rotates around the first hinge axis 330 is not consistent with the direction in which the first bracket 320 rotates around the second hinge axis.
[0037] In the specific shooting process, the camera module will tilt due to jitter, which will eventually affect the shooting quality. In the camera module disclosed in the embodiment of the present invention, the camera 310 can rotate relative to the first bracket 320 about the first hinge axis 330, and the first bracket 320 and the module housing 100 are rotatably connected through the second hinge axis, so the camera 310 can Together with the first bracket 320, it rotates relative to the module housing 100 around the second hinge axis. Since the axis of the first hinge axis 330 and the axis of the second hinge axis intersect or are in different planes, the rotation of the camera 310 in the above two directions can compensate for the angular components of the tilt in these two directions caused by the jitter of the camera module. Implement effective anti-shake on the camera module.
[0038] In a more preferred solution, the axis of the first hinge shaft 330 and the axis of the second hinge shaft may be perpendicular to each other. In this case, the inclination angle caused by the shaking of the entire camera module during the shooting process can be easily broken down into separate parts. The two angle components around the direction of the first hinge axis 330 and the direction around the second hinge axis facilitates the angle compensation of the camera 310 during the rotation process.
[0039] The camera 310 is a relatively precise device. In order to avoid damage to the camera 310 due to assembly, in a more preferred solution, the camera module disclosed in the embodiment of the present invention may further include a second bracket 340, and the camera 310 is fixedly connected to the second bracket 340 . The second bracket 340 is hinged with the first bracket 320 through the first hinge shaft 330. In this case, the camera 310 can follow the second bracket 340 to rotate around the first hinge axis 330. In this case, the camera 310 does not need to be directly rotated and connected, and an assembly method that is relatively easy and not easy to damage the camera 310 can be selected between the camera 310 and the second bracket 340.
[0040] The structure of the first bracket 320 may be various. In a more preferred solution, the first bracket 320 may include a bracket body 321 and a first connecting arm 322, and the first end of the first connecting arm 322 is fixedly connected to the bracket body 321. The second end of the first connecting arm 322 is a free end. The second hinge shaft may be fixed on the module housing 100, the bottom end of the first connecting arm 322 may be provided with a second hinge hole 323, and the second hinge shaft is hinged with the second hinge hole 323. The use of the manner in which the first connecting arm 322 is hinged with the module housing 100 through the second hinge shaft is beneficial to reduce the space occupied by the hinge structure. Moreover, the second end of the first connecting arm 322 is a free end, that is, the first connecting arm 322 has a cantilever structure, and the second end of the first connecting arm 322 can extend into the inner cavity 110 of the housing to achieve an articulated connection. Conducive to the miniaturization design of the entire camera module.
[0041] In a more preferred solution, the first bracket 320 may further include a second connecting arm 324, the first end of the second connecting arm 324 is fixedly connected to the bracket body 321, and the second end of the second connecting arm 324 is a free end. The first hinge shaft 330 is fixed on the second bracket 340 or the camera 310, and the second end of the second connecting arm 324 is provided with a first hinge hole 325, and the first hinge hole 325 is hinged with the first hinge shaft 330. The second end of the two connecting arms 324 can extend into the inner cavity 110 of the housing to achieve hinged connection, which is beneficial to the miniaturized design of the entire module bracket. At the same time, the second connecting arm 324 is a cantilever structure, and the first hinge hole 325 is provided at the free end of the second connecting arm 324, so it is easier to realize the hinged assembly through the deformation of the second connecting arm 324.
[0042] In order to improve the stability of the articulation, in a more preferred solution, there may be two first connecting arms 322 and two second connecting arms 324, and the two first connecting arms 322 may be arranged at a pair of angles on both sides of the camera 310. , The two second connecting arms 324 may be distributed on both sides of the camera 310 at another diagonal. In this case, each first connecting arm 322 can be hinged with a second hinge axis, and each second connecting arm 324 can be hinged with a first hinge axis 330, which can undoubtedly improve the balance of rotation support.
[0043] In the embodiment of the present invention, the bracket body 321 is the main body part of the first bracket 320, and the bracket body 321 can ensure that the first connecting arm 322 and the second connecting arm 324 have strong strength. The structure of the stent body 321 can be various. In a more preferred solution, the support body 321 may be provided with a first escape hole 3211. The lens 311 of the camera 310 may be disposed opposite to the first avoiding hole 3211, and the lens 311 of the camera 310 may pass through the first avoiding hole 3211 to take pictures.
[0044] Specifically, the lens 311 of the camera 310 may be completely located in the inner cavity 110 of the housing, or may be located in the first escape hole 3211, of course, it may also extend out of the housing inner cavity 110 through the first escape hole 3211. In order to avoid the opening of the first avoiding hole 3211 being too large, in a more preferred solution, the lens 311 of the camera 310 is located in the first avoiding hole 3211 or extends out of the module housing 100 through the first avoiding hole 3211. In this case, the opening of the first avoiding hole 3211 can be prevented from being too large under the same shooting field of view, or, under the premise that the opening size of the first avoiding hole 3211 is fixed, the above solution can undoubtedly make the shooting field of view of the lens 311 larger . Of course, the lens 311 of the camera 310 needs the first avoiding hole 3211 to form a gap around the lens 311. During the rotation of the camera 310, the existence of the gap can allow the camera 310 to rotate.
[0045] In order to facilitate manufacturing and assembly, in a more preferred solution, the first bracket 320 may be an integral structure. Specifically, the first bracket 320 may be an integral metal structure.
[0046] In a specific anti-shake work process, the camera 310 needs to rotate around the first hinge axis 330 and/or the second hinge axis. There are many ways to drive the camera 310 to rotate. In a more preferred solution, the electronic device disclosed in the embodiment of the present invention may further include a driving mechanism, and the driving mechanism may include a permanent magnet and an electromagnet. Specifically, the electronic device may be equipped with a driving mechanism matching each direction of movement, and there may be multiple types of driving components, such as direct driving by a driving motor, or driving by a driving motor in cooperation with a transmission mechanism. In a more preferred solution, each driving component may include a permanent magnet and an electromagnet, and the movement is driven by the magnetic field force between the electromagnet and the permanent magnet after being energized.
[0047] In order to improve appearance performance, in a more preferred solution, the module housing 100 can be installed with a first cover 700, which is detachably mounted on the module housing 100. In the assembly process, first The first cover 700 is disassembled, and the camera 310 and other components are assembled into the inner cavity 110 of the housing, and then the first cover 700 is installed. The first cover 700 is provided with a second escape hole 710 and an opening in the inner cavity 110 of the housing Located in the second avoiding hole 710. The module housing 100 with the above structure has good assemblability and is convenient for the installation of the camera 310.
[0048] In the embodiment of the present invention, there may be various mechanisms for driving the rotation of the module housing 100, please refer to image 3 In a specific embodiment, the driving mechanism 200 may include a driving motor 210, a driving gear 220, and a circular arc rack 231.

The use of gear mechanism for power transmission has the advantages of relatively stable transmission and high transmission accuracy. The arc rack 231 can ensure that the module housing 100 rotates within a certain angle, and this structure is more suitable for driving the module housing 100 to rotate within a certain angle range. Of course, the arc rack 231 can be replaced by an annular rack.
[0049] Please refer again image 3 In a more preferred solution, the driving mechanism 200 may include a ring structure 230, the ring structure 230 may be arranged around the module housing 100, the ring structure 230 is fixedly connected to the module housing 100, and the ring structure The piece 230 includes a circular arc rack 231.
