Abstract
Description
Technical Field
[0001] The present invention relates to a lens motor for electronic equipment, and in particular to a lens mount, a periscope lens motor, a camera and an electronic equipment. Background Art
[0002] Today, nearly every portable or non-portable electronic device, such as computers, smartphones, and even pet feeders, is equipped with a camera for both photo and video recording. The lenses used in these cameras can be broadly categorized as short-focus wide-angle lenses or long-focus telephoto lenses. Long-focus telephoto lenses are relatively long, and if they utilize a single optical axis, this increases the thickness of the electronic device, making it difficult to meet the lightweight and thin-profile requirements of mobile devices and ultra-thin displays. Therefore, long-focus telephoto lenses for portable electronic devices and ultra-thin displays typically utilize a periscope-style drive design, utilizing a prism to rotate the lens' optical path 90 degrees, flattening the entire optical system and reducing overall height.
[0003] For example, Corephotonics' patent US10845565B2 discloses a voice coil motor that uses a periscope design to reduce the height of a high-magnification remote zoom device. It also utilizes a ball bearing to support the movement of the movable part, achieving autofocus and bidirectional stabilization. However, its disadvantage is its complex structure. Summary of the Invention
[0004] The object of the present invention is to provide a lens mount with a simple structure and easy assembly, a periscope lens motor using the lens mount, and a camera and electronic equipment equipped with the periscope lens motor.
[0005] A lens mount for holding a camera lens, wherein the lens optical axis is defined parallel to the X-axis. The lens mount comprises: a magnetic conductive element comprising a first magnetic conductive sheet and second and third magnetic conductive sheets extending from opposite sides of the first magnetic conductive sheet, the second and third magnetic conductive sheets being disposed opposite each other; a base comprising a first seat and a second seat disposed opposite each other, the first seat at least enclosing the second magnetic conductive sheet, and the second seat at least enclosing the third magnetic conductive sheet; and a connector connecting the first seat and the second seat, such that the magnetic conductive element, the base, and the connector together form a tubular structure capable of holding the camera lens.
[0006] In one embodiment, the first and second seats are defined as having a first surface facing each other, a second surface facing away from each other, a third surface facing the +Z axis, and a fourth surface facing the -Z axis. A first groove for securing the magnet is formed on each of the second surfaces. The second and third magnetic conductive sheets are respectively located near or exposed at the bottom of the first groove.
[0007] As an embodiment, the opposite side of the first seat and the second seat is defined as the first side, the opposite side is defined as the second side, the side facing the +Z axis direction is defined as the third side, and the side facing the -Z axis direction is defined as the fourth side. Then, at least two second grooves for accommodating balls are formed on the second side of the first seat, and the magnetic conductive element also includes a fourth magnetic conductive sheet extending from the first magnetic conductive sheet or the second magnetic conductive sheet and close to or exposed at the bottom of the second groove. The fourth magnetic conductive sheet is basically parallel to the second magnetic conductive sheet and is spaced apart from the second magnetic conductive sheet.
[0008] As an embodiment, the second groove passes through the third surface of the first seat but does not pass through the fourth surface.
[0009] As an embodiment, at least two third grooves for accommodating balls are formed on the fourth surface of the first seat or the second seat, and the magnetic conductive element also includes a fifth magnetic conductive sheet extending from the first magnetic conductive sheet or the third magnetic conductive sheet and close to or exposed at the bottom of the third grooves. The fifth magnetic conductive sheet is basically parallel to the first magnetic conductive sheet and is spaced apart from the second or third magnetic conductive sheet.
[0010] As an embodiment, the third groove is in the shape of an elongated strip and its direction is parallel to the X-axis.
[0011] As an embodiment, a fourth groove is further formed on the fourth surface of the second seat or the first seat, and a portion of the first magnetic conductive sheet is close to or exposed at the bottom of the fourth groove.
[0012] A periscope lens motor includes a prism module and a lens module, wherein the lens module includes the lens mount described above.
[0013] A camera comprises the periscope lens motor described above.
[0014] An electronic device comprises the camera described above.
[0015] The base of the lens mount of the present invention consists solely of a first seat and a second seat. These are combined via a magnetically conductive element and connectors to form a tubular structure capable of holding a camera lens, resulting in a lightweight and thin mount. The magnetically conductive element can be embedded within the first and second seats via injection molding, simplifying the assembly process. Based on these advantages, the driving magnet for the periscope lens motor can be positioned on one side of the lens mount, simplifying the periscope lens motor's circuit layout and further enhancing the electromagnetic driving force, allowing for the use of larger lenses. When a ball bearing is used to support the lens, the magnetic conductive element serves as the ball bearing's contact surface, increasing the ball bearing's resistance to drops.

[0023] The lens mount, periscope lens motor, camera and electronic device of the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.
[0024] The electronic device of the present invention includes a camera capable of taking photos and videos. The camera includes a lens motor and an imaging module having a CMOS / CCD imaging element, wherein the lens motor is a periscope lens motor for achieving autofocus and shake compensation functions.
[0025] For ease of description, a spatial rectangular coordinate system XYZ is defined. The incident optical axis of the periscope lens motor (i.e., the direction of light entering the prism) is parallel to the Z axis of the coordinate system, and the optical axis of the lens (the lens assembly that implements autofocus) is parallel to the X axis of the coordinate system. The subject is defined as being located in front of the periscope lens motor, that is, in front of the Z axis (the +Z direction), and the imaging module is located on the +X axis side. In the components described below, the end / surface in the +Z direction is referred to as the front end / front surface of the component, and the end / surface in the -Z direction is referred to as the rear end / rear surface of the component, etc.
[0026] The periscope lens motor mainly includes a prism module 1 and a lens module 2 assembled in a housing 4 (please refer to Figure 4Prism module 1 is used to refract light from the front in the Z-axis direction toward the front in the X-axis direction (+X direction). Lens module 2 is primarily used to drive lens 3 along the X-axis to achieve autofocus. The lens mount 21 of the lens module 2 of the present invention has the advantages of a simple structure, light weight, and thin thickness (in the Z-axis direction). It will be appreciated that, in addition to its application in periscope lens motors, this lens mount 21 can also be used in open-loop or closed-loop single-axis motors. Example
[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, in the first embodiment, the lens base 21 of the periscope lens motor of the present invention mainly includes a magnetic conductive element 211, a base 212 and a connecting member 213.
[0028] The magnetic conductive element 211 primarily comprises a first magnetic conductive sheet 2111 substantially parallel to the plane defined by the X-axis and Y-axis (including actual parallelism, non-parallelism due to manufacturing errors but very close to parallelism, and partial non-parallelism but mostly parallelism). The second and third magnetic conductive sheets 2112, 2113 extend from either side of the first magnetic conductive sheet 2111 (on the +Y-axis side and -Y-axis side). The second and third magnetic conductive sheets 2112, 2113 are positioned opposite each other and substantially parallel to the plane defined by the X-axis and Z-axis. The magnetic conductive element 211 is made of a magnetic conductive material.
[0029] The base 212 primarily comprises a first base 2121 and a second base 2122, positioned opposite each other. The first base 2121 encloses the second magnetic conductive sheet 2112 and one end of the first magnetic conductive sheet 2111, while the second base 2122 encloses the third magnetic conductive sheet 2113 and the other end of the first magnetic conductive sheet 2111. The base 212 is made of a non-conductive, non-magnetic material, such as plastic, and is lightweight.
[0030] Connector 213 connects first and second mounts 2121, 2122 at their +Z-axis sides, allowing magnetic element 211, base 212, and connector 213 to collectively form a tubular structure capable of retaining camera lens 3. Connector 212 can be made of either a magnetic or non-magnetic material, preferably metal, which has greater hardness and strength than plastic. Together with magnetic element 211, connector 212 increases the overall strength of the lens mount, effectively protecting lens 3 within.
[0031] In this embodiment, the +Z-axis and -Z-axis sides of the lens mount consist solely of the first magnetic conductive sheet 2111 and the connector 213. The connector 213 can also be a thin metal sheet. This allows the lens mount to be very thin in the Z-axis direction (thickness). When applied to a periscope lens motor, this allows the overall motor thickness to be very thin, enabling its use in ultra-thin electronic devices. Because the base 212 consists solely of the first and second seats 2121 and 2122 enclosing the second and third magnetic conductive sheets 2112 and 2113, the lens mount is lightweight overall. The magnetic conductive element 211 can be embedded within the first and second seats 2121 and 2122 via injection molding, simplifying assembly.
[0032] More specifically, the opposite side of the first seat 2121 and the second seat 2122 is defined as the first surface 2123, the opposite side is defined as the second surface 2124, the side facing the +Z axis direction is defined as the third surface 2125, and the side facing the -Z axis direction is defined as the fourth surface 2126. The first surface 2123 is in an arc shape that matches the side wall of the lens 3. The second surface 2124 is formed with a plurality of holes for fixing the magnets (such as Figure 4 The first groove 2127 of the magnet 241 is formed. The second magnetic conductive sheet 2112 and the third magnetic conductive sheet 2113 are respectively exposed at the bottom of the first groove 2127. In this way, the magnet can be fixed in the first groove 2127 without the use of adhesives or other physical fixings, facilitating assembly.
[0033] A slot 2128 is also formed on the third surface 2125 of each of the first seat 2121 and the second seat 2122. The connector 213 includes a base plate 2131 substantially parallel to the first magnetic conductive sheet 2111 and connecting plates 2132 extending substantially perpendicularly from both ends of the base plate 2131. The connecting plates 2132 are inserted into the slots 2128 to connect the connector 213 to the first seat 2121 and the second seat 2122. The connecting plates 2132 can be bonded to the inner walls of the slots 2128 by an adhesive. The projections of the connecting plates 2132, the second magnetic conductive sheet 2112, and the third magnetic conductive sheet 2113 in the Y-axis direction should overlap to increase the bonding area between the connecting plates 2132 and the slots 2128. It can be understood that in other embodiments, the connecting member may be arc-shaped as a whole, with its two ends inserted into the slots on the third surfaces of the first seat and the second seat, or the connecting member only includes a substrate, and the two ends of the substrate are inserted into the slots formed on the first surfaces of the first seat and the second seat (close to the third surface).
[0034] When the periscope lens motor uses balls as support members, two second grooves 2129 for accommodating the balls 22 are further formed on the second surface 2124 of the first seat 2121, disposed on either side of the first groove 2127. The magnetic conductive element 211 also includes a fourth magnetic conductive sheet 2114 extending from one side of the first magnetic conductive sheet 2111 and exposed at the bottom of the second groove 2129. The fourth magnetic conductive sheet 2114 is substantially parallel to the second magnetic conductive sheet 2112 and spaced apart from the second magnetic conductive sheet 2112. The number of fourth magnetic conductive sheets 2114 is the same as the number of second grooves 2129, and their dimensions should be the same as or slightly larger than the bottom dimensions of the second grooves 2129. They are connected to the first magnetic conductive sheet 2111 via a slender connecting portion. Preferably, the connecting portion has an end 2116 connected to the lower portion of the fourth magnetic conductive sheet 2114 and perpendicular to the fourth magnetic conductive sheet 2114, so that the ball 22 can be easily retained at the corner formed by the lower portion of the fourth magnetic conductive sheet 2114 and the end 2116.
[0035] In this embodiment, the second groove 2129 also extends through the third surface 2125 of the first seat 2121, but not through the fourth surface 2126. This facilitates assembly of the ball 22 by allowing it to be placed into the second groove 2129 from above the first seat 2121. When viewed from the Y-axis, the second groove 2129 is elongated, with a width slightly greater than the diameter of the ball 22, facilitating precise positioning of the ball 22.
[0036] Furthermore, in this embodiment, two third recesses 2120 for accommodating the balls 23 are formed on the fourth surface 2126 of the second seat 2122. The magnetic conductive element 211 also includes a fifth magnetic conductive sheet 2115 extending from the first magnetic conductive sheet 2111 and exposed at the bottom of the third recesses 2120. The fifth magnetic conductive sheet 2115 is substantially parallel to the first magnetic conductive sheet 2111 and spaced apart from the third magnetic conductive sheet 2113. The number of fifth magnetic conductive sheets 2115 is the same as the number of third recesses 2120. Their dimensions should be the same as or slightly larger than the bottom dimensions of the third recesses 2120. They are connected to the first magnetic conductive sheet 2111 via a slender connecting portion. When viewed from the Z-axis, the third recess 2120 is elongated, with its length parallel to the X-axis (i.e., its direction parallel to the X-axis). Its length can be greater than or equal to the distance the mirror seat 21 moves in the X-axis direction. Its width is slightly larger than the diameter of the balls 223, facilitating precise positioning of the balls 23. When the length of the third groove 2120 is equal to the distance that the mirror base 21 moves in the X-axis direction, it also serves as a limiting portion of the mirror base 21 .
[0037] In this way, the mirror base 21 can be movably arranged in a fixed portion by means of the balls 22 and 23 arranged in the second groove 2129 and the third groove 2120. Since the magnet is fixed in the first groove 2127 and is close to or in contact with the second and third magnetic conductive sheets 2112 and 2113, the entire magnetic conductive element is magnetic and is in contact with the base 41 (see FIG. Figure 4 and Figure 5 ) generates an attractive force, thereby having a certain clamping effect on the balls 22 and 23. When the mirror base 21 moves through the balls, the balls are not easy to escape from the second groove and the third groove.
[0038] In this embodiment, to further stabilize the movement of the lens base 21, a fourth groove 21201 is formed on the fourth surface 2126 of the first seat 2121. A portion of the first magnetic conductive sheet 2111 is exposed at the bottom of the fourth groove 21201. This allows a magnet to be positioned at a corresponding position on the fixed portion of the periscope lens motor, causing the magnet to attract the first magnetic conductive sheet 2111 at the bottom of the fourth groove 21201, thereby stabilizing the movement of the lens base 21. It will be appreciated that the fourth groove may be omitted in other embodiments.
[0039] In addition, grooves 21202 are formed at both ends of the first seat 2121 and the second seat 2122 in the X-axis direction for fixing the elastic shock-absorbing element 214, thereby protecting the first seat and the second seat and reducing or absorbing the impact sound.
[0040] In the above embodiment, the outer shape of the mirror base is generally rectangular tubular. It is understandable that in other embodiments, the outer shape of the mirror base may be generally cylindrical tubular. In this case, the surfaces of the first magnetic conductive sheet, the second magnetic conductive sheet, and the third magnetic conductive sheet may all be arc-shaped parallel to the X-axis, as long as the second magnetic conductive sheet and the third magnetic conductive sheet are arranged relative to each other, and the first magnetic conductive sheet and the connecting piece are arranged relative to each other. In other embodiments, the outer shape of the mirror base may also be generally hexagonal or other polygonal columnar, and correspondingly, the first magnetic conductive sheet, the second magnetic conductive sheet, and the third magnetic conductive sheet are also corresponding metal sheets with multiple bends. The actual shapes of the first magnetic conductive sheet, the second magnetic conductive sheet, and the third magnetic conductive sheet do not affect their functions and effects, as long as the second magnetic conductive sheet and the third magnetic conductive sheet are arranged relative to each other, and the first magnetic conductive sheet and the connecting piece are arranged relative to each other.
[0041] In the above embodiment, the second magnetic conductive sheet 2112 and the third magnetic conductive sheet 2113 are respectively exposed at the bottom of the first groove 2127, the fourth magnetic conductive sheet 2114 is exposed at the bottom of the second groove 2129, the fifth magnetic conductive sheet 2115 is exposed at the bottom of the fourth groove 2120, and a portion of the first magnetic conductive sheet 2111 is exposed at the bottom of the fourth groove 21201. It will be appreciated that in other embodiments, the second and third magnetic conductive sheets may be located only near the bottom of the first groove, the fourth magnetic conductive sheet 2114 may be located only near the bottom of the second groove 2129, the fifth magnetic conductive sheet 2115 may be located only near the bottom of the fourth groove 2120, and a portion of the first magnetic conductive sheet may be located only near the bottom of the fourth groove.
[0042] In the above embodiment, the fourth magnetic conductive sheet and the fifth magnetic conductive sheet are extended from the first magnetic conductive sheet. It can be understood that, in other embodiments, the fourth magnetic conductive sheet and the fifth magnetic conductive sheet can be extended from the second magnetic conductive sheet and the third magnetic conductive sheet respectively.
[0043] In the above embodiment, the third groove 2120 is formed on the fourth surface 2126 of the second seat 2122, and the fourth groove 21201 is formed on the fourth surface 2126 of the first seat 2121. It can be understood that, in other embodiments, the positions of the third groove and the fourth groove can be interchanged, and the same function can also be achieved.
[0044] In the above embodiment, the number of the second groove and the third groove is two. It can be understood that the number is not limited to this, and can be three or more. The number of the ball in the second groove and the third groove can be one or more.
[0045] In other embodiments, a groove similar to the second groove 2129 can also be provided on the second surface 2124 of the second seat 2122 to accommodate the ball.
[0046] In the above embodiment, the first seat and the second seat are two components independent of each other and connected by the first magnetic conductive sheet and the connecting sheet. It can be understood that, in other embodiments, the first seat and the second seat are integrally formed, that is, directly connected at one end of the -Z axis, and the first magnetic conductive sheet is also wrapped therein.
[0047] In other embodiments, the fourth magnetic conductive sheet and the fifth magnetic conductive sheet can also be independent of the first magnetic conductive sheet.
[0048] The above grooves are relative to the overall shape of the component. As long as the bottom is lower than the maximum size of the overall shape, it is in a recessed state, and it does not necessarily have a bottom and a side wall surrounding the bottom in a closed loop. In some cases, the groove can only have a bottom and part of the side wall (the side wall is not surrounded by a ring). Embodiment
[0049] This embodiment is a specific embodiment of the mirror seat 21 of Embodiment 1 applied in a periscopic lens motor. Please refer to Figures 4 to 7 The periscopic lens motor mainly includes a prism module 1 and a lens module 2 assembled in a housing 4. The housing 4 includes a base 41 and an upper shell 42 buckled on the base 41. The upper shell 42 has a through hole 421 as a light inlet on the surface in the Z axis direction. The side wall of the upper shell 42 on the +X axis side also forms an opening. The side wall of the base 41 on the +X axis side forms an opening 411 as a light outlet. The base 41 is divided into a first receiving space 412 for receiving the prism module 1 and a second receiving space 413 for receiving the lens module 2.
[0050] The lens module 2 is mainly used to drive the lens 21 to move along the X-axis to achieve the auto-focus function. The lens module 2 mainly includes a lens base 21, ball bearings 22 and 23, and an electromagnetic drive unit 24.
[0051] The electromagnetic drive unit 24 mainly includes a magnet 241 fixed on the mirror base and a coil 242 fixed on the inner wall of the base 41. The magnet 241 and the coil 242 are opposite to each other in the air. The winding direction of the coil 242 is parallel to the Y-axis, and the side of the coil 242 located on the +X-axis side and the side located on the -X-axis side are respectively opposite to different magnetic poles of the magnet 241. In this way, when the coil 242 is energized, a driving force parallel to the X-axis can be generated on the magnet 241. The magnet 241 can drive the mirror base 21 to move along the X-axis under the support of the balls 22 and 23 to achieve automatic focusing. In this embodiment, a coil and two magnets are arranged on each side of the mirror base 21. It can be understood that in other embodiments, two or more coils and three or more magnets can be arranged on each side of the mirror base to achieve a preset driving force.
[0052] The second receiving space 413 of the base 41 is provided with a fifth groove 414 corresponding to the first groove 2127 , a sixth groove 415 corresponding to the second groove 2129 , a seventh groove 416 corresponding to the third groove 2120 , and an eighth groove 417 corresponding to the fourth groove 21201 .
[0053] The fifth groove 414 is used to secure the coil 242. A conductive circuit and a circuit board may be embedded within the base 41. Pads or pins may be formed at the bottom of the fifth groove 414 to electrically connect to the embedded conductive circuit and circuit board. The coil 242 is electrically connected to the corresponding pads or pins. This simplifies the power supply circuitry for the periscope lens motor and reduces assembly complexity.
[0054] The sixth groove 415 cooperates with the second groove 2129 to clamp the ball bearing 22 between the groove bottoms. The sixth groove 415 extends forward along the Z-axis through the upper surface of the sidewall of the base 41, allowing the ball bearing 22 to be assembled between the base 41 and the mirror base 21 from the front along the Z-axis, facilitating assembly. The width of the sixth groove 415 along the X-axis should be greater than or equal to the travel distance of the mirror base 21 along the X-axis. When the width of the sixth groove 415 along the X-axis is equal to the travel distance of the mirror base 21 along the X-axis, the sixth groove 415 also serves as a stop for the mirror base 21.
[0055] The seventh groove 416 cooperates with the third groove 2120 to clamp the ball 23 between the groove bottoms. The length of the seventh groove 416 in the X-axis direction should be greater than or equal to the movement distance of the mirror base 21 in the X-axis direction, and the width in the Y-axis direction should be slightly greater than the diameter of the ball 23. This limits the movement distance of the mirror base 21 in the Y-axis direction without affecting the rolling motion of the ball 23.
[0056] The eighth groove 417 is used to fix the attraction magnet 418 (see Figure 7 ). For the convenience of observation, Figure 7 Only some components are given section lines, for example, the section lines of the base 212 of the mirror holder 21 are not drawn, so as to clearly show the positions of the magnetic conductive element 211 and the connecting member 213.
[0057] During assembly, first, secure the lens 3 within the lens holder 21, the magnet 241 within the first groove 2127, the attraction magnet 418 within the eighth groove 417 (for example, by adhesive bonding), the coil 242 within the fifth groove 414, and the ball 23 within the seventh groove 416. The lens holder 21 is then inserted into the base 41, with the third groove 2120 facing the seventh groove 416 and the sixth groove 415 facing the second groove 2129. Finally, insert the ball 22 from the front in the Z-axis direction into the hole formed by the sixth groove 415 and the second groove 2129 to complete the assembly of the lens module 2. Assembly is very convenient. Because the lens holder 21 can be made very thin in the Z-axis direction, the periscope lens motor can also be made thinner in the Z-axis direction. Because the magnet 241 is fixed to one side of the lens holder 21 and the holder 21 includes a built-in magnetic conductive element 211, the balls 22 and 23 are easy to assemble and are unlikely to become dislodged during operation.
[0058] In this embodiment, the lens module 2 only needs to implement the autofocus function and does not need to implement the anti-shake / shake compensation function. The prism module 1 has the anti-shake / shake compensation function. The prism module 1 mainly includes a prism holder 12 as a movable part for holding the prism 11, a support unit 13 for supporting the prism holder 12 on the base 41, and an electromagnetic drive unit 14 for driving the prism holder 12 to move relative to the base 41. The support unit 13 only includes a rotating shaft. The rotating shaft 13 is integrally formed and made of elastic plastic, such as toughened modified polyoxymethylene resin (Polyoxy Methylene Resin, or acetaln resin, or polyformaldehyde, POM), polybutylene terephthalate (polybutylene terephthalate, PBT), etc., and can achieve elastic and recoverable rotational movement around the Z axis and bending movement along the Y axis.
[0059] Since the prism module 1 does not include the innovations to be protected by the present invention, it will not be described in detail.
