Detailed Description
The invention provides a roller rotating camera assembly, a mobile terminal and a control method, and aims to make the purposes, the technical scheme and the effects of the invention clearer and more definite. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Because the camera on the mobile phone (mobile terminal) of the intelligent terminal is generally provided with a front camera and a rear camera, the front camera and the rear camera are both fixed cameras, when a specific object or person is photographed, the photographed object needs to be photographed at 90 degrees vertically, and the person is difficult to control the 90-degree angle in the actual operation process, so that a natural photo cannot be photographed. In addition, the mobile phone generally needs to be provided with a front camera and a rear camera, so that shooting functions are realized, and if the shooting functions can be realized through only one camera, the part cost of the mobile phone can be saved. Therefore, the invention discloses a roller rotating camera component, which can solve the problem that the shooting angle is difficult to grasp because the angle of the camera cannot be adjusted, and can replace the traditional two cameras by one camera, thereby having the advantages of optimizing the structural design and saving the cost of parts.
Example 1
As shown in fig. 1, the invention provides a roller rotating camera assembly, which is applied to a mobile terminal, such as a mobile phone, a tablet computer and other devices, and in order to make the structure description clearer, the embodiment uses the mobile phone as an example for structure description, and the roller rotating camera assembly in the embodiment includes a camera module 10, where the camera module 10 is used for imaging and shooting. The middle position of the top end of the camera module 10 is usually set, wherein the installation side of the camera module 10 is taken as the upper side, the opposite side of the upper side is taken as the lower side, that is, the long side direction of the mobile phone is taken as the up-down direction, in addition, when the mobile phone is vertically used, the left and right sides of the mobile phone are taken as the left and right directions, and the directions corresponding to the mobile phone screen and the backboard are the front and back directions. The reference of the description of the action structure is set in the above direction in this embodiment. This rotatory camera subassembly of gyro wheel still includes: roller 20, first drive assembly 30, variable speed drive assembly 40, second drive assembly 50. The roller 20 is used for manually pulling, typically the roller 20 is disposed on one of the left and right sides of the mobile phone, for convenience of right-hand single operation of the mobile phone, for example, on the right side, and the axial direction of the roller 20 is set along the front-rear direction, so that the edge portion of the roller 20 protrudes from the right side of the mobile phone, and thus the right-hand is convenient for pulling the roller 20. The first transmission assembly 30 is connected to the roller 20, and converts the pulling of the roller 20 into a rotation in the up-down direction. The first transmission assembly 30 changes the rotation around the front-rear direction to be rotated around the up-down direction. The variable speed drive assembly 40 is coupled to the first drive assembly 30 and is used to vary the rotational speed of the first drive assembly 30. By the transition speed, the camera module 10 is adjusted in speed. The second transmission assembly 50 is connected to the variable speed transmission assembly 40, and converts the rotational direction of the variable speed transmission assembly 40 into a rotation in the left-right direction. The rotation around the up-down direction is turned by the second transmission assembly 50, so that the rotation is changed into the rotation around the left-right direction. The camera module 10 is connected to the second transmission assembly 50, and is driven by the second transmission assembly 50 to rotate around the left-right direction. In this way, the power generated on the roller 20 drives the camera module 10 to rotate after being transmitted by the first transmission assembly 30, the variable speed transmission assembly 40 and the second transmission assembly 50. The camera module 10 can be limited to rotate within a certain range, for example, the camera module 10 cannot rotate to a certain angle towards the direction under the camera module 10 and the accessory in the direction under the camera module, because the direction under the camera module is used for setting the positions of parts such as a mobile phone control circuit and a mobile phone battery, the camera module 10 passing through the position can quickly reach a designated position after rotating clockwise or anticlockwise, and the camera module 10 has no shooting significance. The camera module 10 can rotate clockwise or anticlockwise and then quickly pass through the area to reach a specified angle position for shooting without limiting.
Through above-mentioned scheme, through setting up gyro wheel 20 on the cell-phone, when shooing, manually stir gyro wheel 20, roll and rotate and drive first drive assembly 30 and carry out the transmission, change limit with power take off's direction through first drive assembly 30, power conduction is to variable speed drive assembly 40, carry out the speed change through variable speed drive assembly 40, variable speed drive assembly 40 is with power conduction to second drive assembly 50, change power direction again through second drive assembly 50 to drive the camera module 10 of another position and rotate. When the camera needs to be rotated at a large angle, the speed of the variable speed transmission assembly 40 changes the speed of the camera module 10, so that the rotation speed of the camera module 10 becomes fast, and the large angle change is realized rapidly. When the small-angle fine adjustment is needed, the speed of the camera module 10 is reduced through the variable speed transmission assembly 40, and the rotation speed of the camera module 10 is reduced, so that the small-angle fine adjustment is realized. Like this through rotating camera module 10, make camera module 10 can rotate and change, according to shooting requirement, adjust the camera and shoot to suitable angle to guarantee to shoot clear natural photograph. Moreover, the camera module 10 can realize 180 degrees of overturning, and after the front camera is used, the front camera can be used as a back camera through overturning, so that the front and back cameras can be realized through one camera module 10, and the number of cameras on the existing mobile phone is reduced.

Allowing the roller 20 to be manually pushed on the right side of the handset. In addition, it is easy to think that the roller 20 may be disposed in the mobile phone instead of protruding from the side of the mobile phone, and then driven by the motor, so that automatic driving can be realized, and intelligent rotation of the camera module 10 can be realized. The first transmission assembly 30 in this embodiment includes: a drive bevel gear 31, and a driven bevel gear 32. The drive bevel gear 31 is fixedly connected to the connecting post 21, the driven bevel gear 32 is meshed with the drive bevel gear 31, and the driven bevel gear 32 is connected with the variable speed transmission assembly 40. The drive bevel gear 31 is disposed coaxially with the coupling post 21, and the driven bevel gear 32 has an axial direction in the up-down direction. The roller 20 rotates to drive the connection post 21 to rotate, the drive bevel gear 31 is driven to rotate through the connection post 21, the drive bevel gear 31 transmits power to the driven bevel gear 32, and the driven bevel gear 32 rotates around the up-down direction, so that the change of the rotation direction is realized.
As shown in fig. 1 and 2, the driven bevel gear 32 in the present embodiment is connected to a first rotating shaft 33, and the first rotating shaft 33 is rotatably disposed in a housing 70 of the mobile phone, specifically, the first rotating shaft 33 may be fixed in the housing through a bearing seat, so that the rotating arrangement of the first rotating shaft 33 may be achieved. The first rotation shaft 33 is provided in the up-down direction. The driven bevel gear 32 drives the first rotating shaft 33 to rotate, thereby transmitting power. The variable speed drive assembly 40 includes: a first driving gear 41 and a first driven gear 42. The first driving gear 41 is connected to the first rotating shaft 33, and the first driven gear 42 is meshed with the first driving gear 41. The first driven gear 42 is connected to the second drive assembly 50. After the first driving gear 41 and the second driven gear 45 are meshed, a transmission ratio is formed between the first driving gear 41 and the second driven gear 45, the first rotation shaft 33 rotates to drive the first driving gear 41 to rotate, the first driven gear 42 is driven to rotate through the first driving gear 41, and then the second transmission assembly 50 is driven to move through the first driven gear 42. Because of the transmission ratio, when the motion of the first rotating shaft 33 is transmitted to the second transmission assembly 50, the speed is changed, and the speed change can be that the stirring amplitude of the roller 20 is small, so that the rotation amplitude of the second transmission assembly 50 is large, and the rotation amplitude of the camera module 10 is driven to be large. Alternatively, the roller 20 has a large pulling amplitude, so that the second transmission assembly 50 has a small rotating amplitude, and thus the camera module 10 is driven to rotate by a small rotating amplitude.
The first driven gear 42 is connected with a second rotating shaft 43, the second rotating shaft 43 is arranged along the up-down direction, the second rotating shaft 43 is arranged in parallel with the first rotating shaft 33, and the first driven gear 42 is connected with the second transmission assembly 50 through the second rotating shaft 43. The second rotating shaft 43 in the present embodiment is rotated in the up-down direction by the driving of the first driven gear 42.
The variable speed drive assembly 40 in this embodiment further includes: a second driving gear 44 provided on the first rotating shaft 33, a second driven gear 45 provided on the second rotating shaft 43, and a pushing portion 60. One of the gear sets formed by the second driving gear 44 and the second driven gear 45 is meshed with the gear set formed by the first driving gear 41 and the first driven gear 42, and the other is not meshed, so that the transmission of the power on the first rotating shaft 33 to the second rotating shaft 43 can be ensured. The two gearsets have different gear ratios, respectively, so that a shift between the different gear ratios is achieved by the movement of the second rotation shaft 43. Mainly in order to realize when needing to adjust camera module 10 to a certain position fast, wherein first gear train meshes, and the finger stirs gyro wheel 20's a small margin, enables camera module 10 and rotates by a wide margin, reaches the position fast. When the camera needs to be finely tuned, the camera is switched to the other gear set for meshing, the finger can stir the roller 20 greatly, the camera module 10 can rotate in a small range, fine tuning operation of the camera is realized, and more fine rotation of the camera module 10 to a shooting angle is facilitated. Therefore, the pushing part 60 is configured to push the second rotating shaft 43, so that the first driven gear 42 is separated from the first driving gear 41, and the second driven gear 45 is engaged with the second driving gear 44; or the first driven gear 42 is engaged with the first driving gear 41, and the second driven gear 45 is disengaged from the first driven gear 42. The transmission ratio between the first driving gear 41 and the first driven gear 42 is different from the transmission ratio between the second driving gear 44 and the second driven gear 45. Through setting up different transmission ratios between two gear sets, realize the function of quick rotation to shooting angle or meticulously adjusting shooting angle after making two gear sets mesh respectively.
As shown in fig. 2, the pushing part 60 in the present embodiment includes: the push-out magnetic attraction part 61, the first electromagnetic member 62, the retraction magnetic attraction part 63 and the second electromagnetic member 64, the push-out magnetic attraction part 61 is arranged on the second rotating shaft 43, the retraction magnetic attraction part 63 is arranged on the second rotating shaft 43, the push-out magnetic attraction part 61 and the retraction magnetic attraction part 63 are respectively positioned at two ends of the second rotating shaft 43, and the second rotating shaft 43 is not fixed in a mobile phone shell, but can be arranged in the mobile phone shell in a vertical moving way, and can also be arranged in the mobile phone shell in a vertical rotating way. The first electromagnetic member 62 is matched with the push-out magnetic attraction portion 61, and is used for attracting the push-out magnetic attraction portion 61 after being electrified. The first electromagnetic member 62 is matched with the push-out magnetic attraction portion 61 and is used for attracting the retraction magnetic attraction portion 63 after being electrified. The first electromagnetic member 62 and the second electromagnetic member 64 are located between the push-out magnetic attraction portion 61 and the retract magnetic attraction portion 63. In this embodiment, in the initial state, the first driving gear 41 is meshed with the first driven gear 42, for example, to achieve a function of rapidly rotating to a shooting angle, when the function of finely adjusting the shooting angle is required to be converted, the first electromagnetic member 62 is energized after receiving the instruction, the first electromagnetic member 62 generates suction force, the second electromagnetic member 64 is not energized, no suction force is generated, and the push-out magnetic attraction portion 61 is attracted, so that the push-out magnetic attraction portion 61 moves down, the push-out magnetic attraction portion 61 that moves down drives the second rotating shaft 43 to move down, the first driven gear 42 is separated from the first driving gear 41, and the second driven gear 45 is meshed with the second driving gear 44, so that power is transmitted from the first rotating shaft to the second rotating shaft through the second driving gear 44 and the second driven gear 45, thereby achieving a function of finely adjusting the shooting angle. When the shooting angle is required to be changed from the function of fine adjustment to the function of realizing rapid rotation to the shooting angle, the second electromagnetic member 64 is electrified after receiving the instruction, the second electromagnetic member 64 generates suction force, the first electromagnetic member 62 is not electrified, suction force is not generated, and accordingly the second electromagnetic member 64 attracts the retracting magnetic part 63, the retracting magnetic part 63 is moved upwards, the moving retracting magnetic part 63 drives the second rotating shaft 43 to move upwards, the second driven gear 45 is separated from the second driving gear 44, and the first driven gear 42 is meshed with the first driving gear 41 again, so that power is transmitted from the first rotating shaft to the second rotating shaft through the second driving gear 44 and the second driven gear 45. Thereby realizing the function of rapidly rotating to a shooting angle.
In this embodiment, the triggering of the instruction for switching the two functions may be selected by other keys, or selected by touch screen software, or may be automatic. In this embodiment, an automatic control manner is preferably adopted, specifically: the wheel rotation camera assembly further comprises a speed detector 65, the speed detector 65 being located on one side of the wheel 20 and being arranged to detect the speed of the wheel 20. The speed detector 65 is used to control the energization of the first solenoid 62 or the energization of the second solenoid 64 in accordance with the detected speed. The specific operation principle is that when the roller 20 rotates, the speed detector 65 is activated to detect the rotation speed of the roller 20. When the user needs to change the position of the camera module 10 greatly, the user can toggle the roller 20 faster. And when fine adjustment is required, the roller 20 is typically shifted slower. Therefore, when the speed detector 65 detects that the speed of the roller 20 reaches a preset value, and the preset value is relatively fast, the second electromagnetic member 64 is started to engage the first driving gear 41 with the first driven gear 42, so as to realize the function of fast rotation to the shooting angle. When the speed detector 65 detects that the speed of the roller 20 is lower than the preset value, the first electromagnetic member 62 is started to enable the second driving gear 44 and the second driven gear 45 to be meshed, so that the function of finely adjusting the shooting angle is realized.
To optimize the structure of the present embodiment, the second driving gear 44 is located between the first driving gear 41 and the driven bevel gear 32, and the second driven gear 45 is located on a side of the first driven gear 42 facing away from the second transmission assembly 50. The transmission ratio between the first driving gear 41 and the first driven gear 42 is smaller than the transmission ratio between the second driving gear 44 and the second driven gear 45. When the first driving gear 41 and the first driven gear 42 are meshed, the transmission ratio is small, the rotation speed change of the driven camera module 10 is small, or the rotation speed of the camera module 10 is added, so that the function of rapidly rotating to a shooting angle is realized. When the second driving gear 44 and the second driven gear 45 are engaged, the transmission ratio is large, and the rotation speed of the camera module 10 is much slower than that of the poked roller 20, so that the function of finely adjusting the shooting angle is realized.
The second transmission assembly 50 in this embodiment includes: cylindrical gear 51, face gear 52. The cylindrical gear 51 is coaxially disposed on the second rotation shaft 43. The face gear 52 is meshed with the spur gear 51 through face teeth. The face gear 52 has a concave structure in the middle, and teeth are provided on the surface without the concave. The face gear 52 is engaged with the spur gear 51, the axial direction of the spur gear 51 is set up in the up-down direction, and the spur gear 51 is set up in the axial direction by a certain length so as not to be disengaged from the face gear 52 when the spur gear 51 moves with the second rotation shaft. The axial direction of the face gear 52 is along the left-right direction, the face gear 52 is coaxially connected with a third rotating shaft 53, the third rotating shaft 53 is arranged along the left-right direction, and the third rotating shaft 53 is fixedly connected with the camera module 10.
In this way, the power of the rotation in the up-down direction on the second rotation shaft 43 is converted into the power of the rotation in the left-right direction by the spur gear 51 and the face gear 52. Thereby enabling the camera module 10 to rotate about the left-right direction.

The display screen is a display screen capable of realizing the on-screen display technology, and a plurality of on-screen display technologies are already presented in the mobile phone at present, and the specific structure of this embodiment is not described in detail. Through the display technology under the screen, according to the specific structure description of the first embodiment, the camera module 10 can realize the function of shooting towards the front end, the rear end and the upper end of the mobile phone, and at least can perform multi-angle adjustment in the three directions.

step S100, detecting and acquiring the stirring rotation speed of the roller 20;

When the camera needs to be rotated at a large angle, the speed of the variable speed transmission assembly 40 changes the speed of the camera module 10, so that the rotation speed of the camera module 10 becomes fast, and the large angle change is realized rapidly. When the small-angle fine adjustment is needed, the speed of the camera module 10 is reduced through the variable speed transmission assembly 40, and the rotation speed of the camera module 10 is reduced, so that the small-angle fine adjustment is realized. Like this through rotating camera module 10, make camera module 10 can rotate and change, according to shooting requirement, adjust the camera and shoot to suitable angle to guarantee to shoot clear natural photograph. Moreover, the camera module 10 can realize 180 degrees of overturning, and after the front camera is used, the front camera can be used as a back camera through overturning, so that the front and back cameras can be realized through one camera module 10, and the number of cameras on the existing mobile phone is reduced.
It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
