The disclosure provides an aperture structure, a camera and a terminal device, wherein the aperture structure and the camera are applied to the terminal device, the aperture structure is matched with the camera of the terminal device, and the terminal device can be portable electronic devices such as a mobile phone, a tablet personal computer and the like. The aperture structure comprises a guide structure, a driving structure and a shading component, wherein the shading component comprises a plurality of shading units, the number of the shading units is greater than or equal to three, the shading units are spliced and connected to form a light through hole, the driving structure applies driving force to at least one shading unit in the plurality of shading units, the plurality of shading units are driven to move along the guide structure respectively, and any two adjacent shading units relatively slide along a splicing seam of the two shading units to adjust the size of the light through hole. The driving structure is used for applying driving force to the light shielding unit, the light shielding unit is driven to move along the guide structure, the size of the light passing hole is regulated, and continuous regulation of the light inlet quantity is realized. When the light is bright and sufficient, the driving structure drives the shading unit to move along the guiding structure, so that the size of the light passing hole is reduced, and the optimal resolution picture is obtained; under the dim environment of light, through the removal of drive structure drive light screen unit along guide structure, increase the size of light hole, guarantee to get into the intake of making a video recording the module sufficient to obtain the pure picture that exposes higher, noise is lower.
As shown in fig. 1 and 2, in an exemplary embodiment, the present embodiment provides an aperture structure 1 including a guide structure 11, a driving structure 12, and a light shielding member 13. The light shielding assembly 13 comprises a plurality of light shielding units 131, the number of the light shielding units 131 is greater than or equal to three, the light shielding units 131 are spliced and connected to form a light through hole 1311, and the light entering amount of the camera module 2 on the terminal equipment is adjusted by adjusting the size of the light through hole 1311. When the amount of light input needs to be increased, the control light passing hole 1311 becomes large; when the light quantity needs to be reduced, the light through hole 1311 is controlled to be reduced so as to realize continuous adjustment of the aperture size of the camera, and when a user shoots at a terminal device such as a mobile phone, the light quantity is adjusted according to the environment, so that a clearer picture is obtained.
In this embodiment, still referring to fig. 1 and 2, the driving structure 12 applies a driving force to at least one light shielding unit 131 of the plurality of light shielding units 131, so as to drive the plurality of light shielding units 131 to move along the guiding structure 11, and any two adjacent light shielding units 131 slide relatively along the splicing seams thereof, so as to adjust the size of the light passing hole 1311. In this embodiment, the light shielding component 13 can be equally divided into a plurality of light shielding units 131 with fan-shaped structures under the initial condition, that is, the unused state, and the light through holes 1311 are in the completely closed state, so that the light shielding component 13 can be used for shielding dust and the like when the camera module 2 is not used, protecting the camera module 2, and prolonging the service life of the camera module 2. Of course, the light shielding assembly 13 may be equally divided into a plurality of light shielding units 131 having an isosceles triangle structure, or may be equally divided into a plurality of light shielding units 131 having an isosceles trapezoid structure, so long as the light shielding units 131 are mutually spliced and can slide relatively along the splice seam, so as to form the adjustment of the light through hole 1311.
Of course, it is understood that, since the light shielding assembly 13 includes a plurality of light shielding units 131, when the driving structure 12 applies the driving force to the light shielding assembly 13, the driving force may be applied to all of the light shielding units 131 at the same time, the driving force may be applied to some of the light shielding units 131, and the driving force may be applied to only one of the light shielding units 131. In one example, the driving structure 12 may apply a driving force to any one light shielding unit 131 among the plurality of light shielding units 131, and upon applying the driving force, the driving structure 12 may apply the driving force to the light shielding unit 131 through a moving part 1313 provided on the light shielding unit 131. Since the plurality of light shielding units 131 are spliced with each other, the light shielding units 131 to which the driving force is applied transmit the driving force to the light shielding units 131 adjacent thereto through the surface contact, and further transmit the driving force to all of the light shielding units 131, so that all of the light shielding assemblies 13 move along the guide structure 11.
In another example, the driving structure 12 may also apply driving forces to two, three or more light shielding units 131 of the plurality of light shielding units 131 simultaneously, so as to improve the reliability of the movement of the light shielding units 131 along the guiding structure 11, to more quickly drive the plurality of light shielding units 131 to move, and to quickly adjust the opening size of the light passing hole 1311, thereby adjusting the light inlet amount of the light shielding assembly 13.
In this embodiment, as shown in fig. 6, the light shielding component 13 includes six light shielding units 131, each light shielding unit 131 is fan-shaped, the six light shielding units 131 can be spliced to form the circular light shielding component 13, and the driving structure 12 can apply driving force to each light shielding unit 131 respectively to more efficiently and rapidly drive the light shielding units 131 to slide relatively, so as to adjust the size of the light through hole 1311.
As shown in fig. 1, 2, and 6, in another exemplary embodiment, the aperture structure 1 further includes a mounting portion 14, and the mounting portion 14 includes a mounting body 141 for mounting the light shielding unit 131. The mounting portion 14 is provided with a through hole 142 for light entrance, and the through hole 142 is a circular hole. The guide structure 11 includes a plurality of guide grooves 111 disposed on the mounting portion 14, the plurality of guide grooves 111 are disposed on the radial outer side of the through hole 142, the plurality of guide grooves 111 are disposed around the through hole 142, and the guide grooves 111 are disposed corresponding to the light shielding units 131, wherein the plurality of guide grooves 111 are connected end to end in sequence to form a regular polygon. For example, the light shielding assembly 13 includes six light shielding units 131, the guiding structure 11 includes six guiding grooves 111, and the six guiding grooves 111 may be connected end to form a regular hexagon.
In this embodiment, referring still to fig. 1, 2 and 6, the light shielding unit 131 includes a limiting portion 1312, and the limiting portion 1312 may be a square slider, and the limiting portion 1312 slides along the corresponding guide groove 111 under the action of the driving force. When the driving structure 11 drives the light shielding units 131, the limiting portion 1312 cooperates with the guide groove 111, so that the light shielding units 131 move along a predetermined track, and the splicing form between the light shielding units 131 is changed, so as to control the scaling of the light passing holes 1311. For example, under the initial condition of the light shielding assembly 13, the six fan-shaped light shielding units 131 are spliced to form the circular light shielding assembly 13, the limiting portion 1312 of the light shielding unit 131 is located in the middle of the corresponding guide groove 111, at this time, the opening of the light passing hole 1311 is the smallest, and the distance between the tip portions of any two adjacent fan-shaped light shielding units 131 is the smallest.
In this embodiment, referring still to fig. 1, 2 and 6, when the driving structure 12 applies a driving force to the light shielding units 131, the light shielding units 131 move in a directional manner along the predetermined track corresponding to the guide grooves 111 through the limiting portions 1312, and any two adjacent fan-shaped light shielding units 131 slide relatively along the splice seams thereof, so as to adjust the size of the light passing hole 1311. The predetermined trajectory may be, for example, a trajectory in which the limit portion 1312 moves toward the first end of the guide groove 111 with the middle of the corresponding guide groove 111 as a starting point, and when the limit portion 1312 moves to the first end, the opening of the light-passing hole 1311 is the largest at this time, and the distance between the tip ends of any two adjacent fan-shaped light-shielding units 131 is the largest. Of course, it is understood that the predetermined track may be a moving track of the limiting portion 1312 moving toward the second end of the guide groove 111 with the middle of the corresponding guide groove 111 as a starting point, that is, in this embodiment, the mode of increasing the light-transmitting hole 1311 has two modes, and the size of the light-transmitting hole 1311 may be adjusted by selecting any mode through the terminal device.
When a user shoots by using terminal equipment such as a mobile phone, the size of the light-passing hole 1311 is continuously adjusted along with the change of shooting environment, so that more proper light-entering quantity is obtained, and therefore, the problem of loss caused by sliding between the limiting part 1312 and the guide groove 111 influences the adjustment of the light-entering quantity, even the condition that the adjustment cannot be performed possibly occurs, the adjustment of the light-passing hole 1311 can be realized in two ways, the practicability of the terminal equipment is improved, and the situation that the light-passing hole 1311 generates excessive loss due to the adoption of a single adjusting mode and influences the service life of the aperture structure 1 is avoided. In the present embodiment, the specific structure of the mounting body 141 is not limited, and the regular polygonal guide groove 111 may be implemented and the light shielding unit 131 may be mounted in a matched manner.
Here, the above-described manner of adjusting the light-passing hole 1311 is merely an example, and is not limited to the present application, and the number of the light-shielding units 131 and the corresponding guide grooves 111 may be 4 or 8, and the starting positions of the stopper portions 1312 on the light-shielding units 131 on the corresponding guide grooves 111 may also be changed accordingly, specifically, the actual design structure may be adopted.
As shown in fig. 1, 5 and 6, in another exemplary embodiment, the driving structure 12 includes a first limiting portion 121, the light shielding unit 131 includes a moving portion 1313, where the moving portion 1313 may be a cylindrical structure, and the moving portion 1313 is disposed on a side of the light shielding unit 131 away from the limiting portion 1312, that is, the moving portion 1313 is disposed on a side opposite to the limiting portion 1312, or it may be understood that the moving portion 1313 is disposed opposite to the limiting portion 1312. The first limiting portions 121 are provided corresponding to the moving portions 1313, and the moving portions 1313 are slidably provided on the corresponding first limiting portions 121. For example, the driving structure 12 rotates under the action of an external force, the first limiting portion 121 on the driving structure 12 follows the movement, and as the driving structure 12 rotates, the moving portion 1313 slides relative to the first limiting portion 121, and at the same time, the moving portion 1313 and the first limiting portion 121 abut against each other, so as to transmit the torque applied to the driving structure 12 to the moving portion 1313. The light shielding unit 131 is further provided with a limiting portion 1312, and a force acting on the moving portion 1313 drives the limiting portion 1312 to slide along the guide groove 111 to drive the light shielding unit 13 to move relative to the mounting portion 14.
In this embodiment, referring still to fig. 1, 5 and 6, the driving structure 12 further includes a driving body 122, the driving body 122 is a circular cover, the driving body 122 is provided with a light inlet 1221 for light inlet, and the first limiting portion 121 may be, for example, a chute disposed on the driving body 122, and the chute extends along a radial direction of the light inlet 1221. The number of the sliding grooves may be one or a plurality of the sliding grooves, and the sliding grooves are arranged corresponding to the moving parts 1313 on the light shielding units 131, and the corresponding arrangement includes a number corresponding arrangement and a position corresponding arrangement. In the assembled state, the moving portion 1313 extends into the chute, the driving body 122 rotates under the action of an external force, the chute on the driving body 122 rotates along with the driving body, and the side wall of the chute abuts against the outer wall of the moving portion 1313 so as to apply an acting force to the moving portion 1313. Since each light shielding unit 13 is provided with the moving portion 1313 and the limiting portion 1312, when a force is applied to the moving portion 1313, the light shielding unit 13 is integrally forced, and the limiting portion 1312 is driven by the force to move linearly along the guide groove 111 on the mounting portion 14. During the movement of the moving portion 1313 along the guide groove 111, the driving body 122 rotates relative to the mounting portion 14, so that the moving portion 1313 also slides along the extending direction of the chute. Wherein, the wall surface of one side of the mounting portion 14 is recessed to form a plurality of guide grooves 111, each guide groove 111 includes a first end and a second end, and the moving portion 1313 moves between the first end and the second end of the first limiting portion 121 when the limiting portion 1312 moves between the first end and the second end along the guide groove 111 corresponding thereto.
In one example, in the initial condition of the light shielding assembly 13, six fan-shaped light shielding units 131 are still spliced to form the circular light shielding assembly 13, at this time, the opening of the light passing hole 1311 is the smallest (refer to fig. 3), and the moving portion 1313 is located at the first end of the chute, where the first end is the end of the chute near the central axis of the driving body 122. When the driving structure 12 rotates under the action of external force, the sliding groove follows the driving body 122 to rotate, the side wall of the sliding groove is connected with the moving part 1313 in an abutting manner, the sliding groove pushes the moving part 1313 to move, the moving part 1313 drives the light shielding unit 131 to move, and the light shielding unit 131 moves along the preset track of the corresponding guide groove 111 in an oriented manner through the limiting part 1312.
In this example, when the chute pushes the moving portion 1313 to move, the moving portion 1313 is relatively displaced from the chute, the moving portion 1313 moves toward the second end of the chute with respect to the first end of the chute, and when the stopper portion 1312 moves to the first end of the corresponding guide groove 111, the opening of the light passing hole 1311 is maximized (see fig. 4), and the moving portion 1313 is located at the middle of the chute. When the limiting portion 1312 moves to the second end of the corresponding guide groove 111, the moving portion 1313 is also located at the middle of the chute. The chute may extend through the driving body 122 along the axial direction of the driving body 122, or may not extend through the driving body 122, so as to improve the sealing performance of the aperture structure, and be used for shielding dust and the like, and protecting the camera module 2 under the condition that the chute does not extend through the driving body 122.
Here, it should be noted that, one of the light shielding units 131 on the light shielding assembly 13 may have a moving portion 1313, or all of the light shielding units 131 may have moving portions 1313, the driving body 122 is provided with sliding grooves corresponding to the moving portions 1313 on the light shielding units 131, the number of the sliding grooves is consistent with the number of the moving portions 1313, and the number of the light shielding units 131 specifically provided with the moving portions 1313 is based on the actual structural design, which is not repeated herein. In addition, when the size of the light-passing hole 1311 is adjusted, the relative position between the moving portion 1313 and the chute is only illustrated, and the relative position between the moving portion 1313 and the chute, the number of the light-shielding units 131, the length of the chute, and the position of the chute are related, and the relative position between the moving portion 1313 and the chute is determined by the actual structural design and will not be described again herein.
As shown in fig. 1 and 5, in another exemplary embodiment, the driving body 122 further includes a protrusion 1222, where the protrusion 1222 is disposed near the side of the mounting portion 14, and the protrusion 1222 has an annular structure, and the protrusion 1222 is located between the first limiting portion 121 and the outer edge of the driving body 122. The mounting body 141 of the mounting portion 14 is provided with a flange portion 1411 along a circumferential direction, the flange portion 1411 has an annular structure, an outer diameter of the flange portion 1411 is larger than an outer diameter of a protrusion 1222 on the driving body 122, the protrusion 1222 is in contact connection with the flange portion 1411, and the flange portion 1411 is used for supporting the driving body 122.
In another exemplary embodiment, as shown in fig. 1, the aperture arrangement 1 further comprises a power take-off 15, which power take-off 15 may be, for example, a motor or other driving device that can achieve an output torque. The power output device 15 is connected to the driving body 122, and the power output device 15 outputs torque to drive the driving body 122 to rotate around its central axis. The power output device 15 is connected with the driving body 122 through gear transmission, and the power output device 15 drives the shading unit 131 to move so as to realize the adjustment of the optical aperture structure 1.
In this embodiment, still referring to fig. 1, the driving structure 12 further includes a transmission gear 123, and a middle portion of the transmission gear 123 is fixedly connected to the driving shaft of the power output device 15. Along the circumferential direction of the driving body 122, a rack 124 is disposed at the edge of the driving body 122, the rack 124 and the first limiting portion 121 are located on the same surface, and the rack 124 is meshed with the transmission gear 123. The power output device 15 controls the transmission gear 123 to rotate along the central axis of the transmission gear 123 to be meshed with the rack 124, and drives the driving body 122 to rotate around the central axis of the transmission gear, so that the splicing form of the light shielding unit 131 is changed, the size of the light passing hole 1311 is regulated, continuous regulation of the light inlet amount is realized, and a picture with higher quality is obtained. The shape of the light-passing hole 1311 formed by the light-shielding unit 131 may be, for example, a polygonal aperture, and when the number of the light-shielding units 131 is increased, the shape of the light-passing hole 1311 approaches to a circular shape, so that the accuracy of adjusting the light-entering amount is higher, the amount of light entering the image capturing module 2 from each angle is more balanced, and the quality of the captured image satisfies the requirements of users.
