The carrier reinforcement is used to increase the strength of at least the sides and bottom of the carrier body, and the carrier mounting groove is disposed on the bottom surface of the carrier body.

[0010] In some embodiments, an installation member is fixedly provided on the outer wall surface of the carrier mounting portion, the installation member extends along the second direction, and a rolling space for the second rolling element is formed between the second base mounting groove, the installation member and the carrier reinforcement member, and the outer peripheral surface of the second rolling element is in contact with the installation member and the carrier reinforcement member.

[0011] In some embodiments, the outer peripheral surface of the first rolling element abuts against the carrier connection portion and the base reinforcement, respectively.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0036] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0039] Currently, in the field of periscope motors, the support structure plays a decisive role. To enable smooth lens movement during focusing, a support structure that provides efficient support and reduces friction is needed. However, existing periscope motor support structures, such as spring-loaded or ring-type support structures, while meeting the load-bearing requirements, have limitations in stability, reliability, and accuracy in terms of travel, especially large-travel motion. These traditional solutions often fail to achieve ideal results, particularly when high precision in lens movement and load-bearing capacity are required.

[0040] To address the shortcomings of existing load-bearing structures, this application proposes a novel support rolling scheme by simplifying the structure of the periscope motor support device and optimizing the moving support method. This scheme simplifies the types and number of support components and optimizes the support motion scheme, thereby improving the overall strength and durability of the periscope motor. Furthermore, the rational distribution of the balls and rollers ensures higher stability of the carrier during movement, thus guaranteeing the performance and long service life of the periscope motor.

[0041] In this application, "multiple" means two or more (including two).

[0042] The specific embodiments of this application will now be described in conjunction with the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of the optical camera device provided in the embodiments of this application; Figure 2 for Figure 1 Exploded view.

[0044] The periscope motor support device 10 provided in this application is used in optical imaging equipment in fields such as mobile phones, security, low-altitude flight, and aerospace. It mainly includes a base 11, a carrier 12, a first rolling element 13, and a second rolling element 14. The carrier 12 is disposed inside the base, and the base 11 is used to accommodate and fix the carrier 12. The carrier 12 is used to support the lens 20.

[0045] The base 11 includes a base body 111 and a base reinforcement 112. At least a portion of the base reinforcement 112 is embedded in the base body 111, which can increase the strength of the base body 111. The base body 111 has a first base mounting groove 111a and a second base mounting groove 111b. The first base mounting groove 111a extends along the second direction Y.

[0046] The base body 111 can be a single rectangular or cylindrical box structure with an internal cavity, or it can be a complex box structure composed of single boxes and plates or blocks. This application embodiment does not limit this. The material of the base body 111 can be, but is not limited to, injection molded parts, such as alloy materials like aluminum alloy and titanium alloy, or it can be a polymer material or a composite material. This application embodiment also does not limit this. The base body 111 is used to accommodate a carrier. The base body 111 can have various structures, as long as the load-bearing and positioning requirements are met. At least a portion of the base reinforcement 112 is embedded inside the base body 111 to enhance the overall structural strength of the base body 111. The base reinforcement 112 can be made of steel, stainless steel, alloy, etc.

[0047] like Figure 3 and Figure 4 As shown. The base body 111 has a first base mounting groove 111a and a second base mounting groove 111b. The first base mounting groove 111a and the second base mounting groove 111b can be located on the side or bottom of the base body 111. The first base mounting groove 111a and the second base mounting groove 111b can be located on the same side of the base body 111 or distributed on different sides of the base body 111. In terms of quantity, there can be one, two, or more first base mounting grooves 111a and second base mounting grooves 111b. A first rolling element 13 is provided in the first base mounting groove 111a, which can provide support for the rolling of the first rolling element 13 and guide and position the lens 20 during movement. A second rolling element 14 is provided in the second base mounting groove 111b, which can provide support and limit the rolling of the second rolling element 14 when the lens 20 is focusing.

[0048] The first base mounting groove 111a can be a strip-shaped groove extending along the second direction Y, or it can be a square or rectangular groove. When a strip-shaped groove is used, it facilitates the movement of the rolling body along the second direction Y during the focusing process of the lens 20. When a square or rectangular groove is used, it facilitates the rolling body to roll along the groove. The second base mounting groove 111b can at least provide guidance and limitation for the rolling of the second rolling body 14. It can be a square or rectangular groove, providing support for the second rolling body 14 while meeting the rolling requirements of the second rolling body 14. It can also be a strip-shaped groove, which facilitates the rolling and movement of the second rolling body 14 along the groove.

[0049] The carrier 12 is disposed within the base 11. The carrier 12 includes a carrier body 121 and a carrier reinforcement 122. At least a portion of the carrier reinforcement 122 along the circumferential direction is embedded in the carrier body 121. The carrier body 121 has a carrier mounting groove 121a, which is distributed along the second direction Y. The carrier mounting groove 121a is adapted to fit with the first base mounting groove 111a to form a rolling element mounting cavity.

[0050] The carrier body 121 can be a single block or box structure with a lens mounting cavity, or it can be a complex structure composed of individual blocks, boxes, or plates. This embodiment of the application does not limit this. The carrier reinforcement 122 enhances the overall structural strength of the carrier body 121. The carrier mounting groove 121a is correspondingly provided with the first base mounting groove 111a, and the two mounting grooves constitute a rolling element mounting cavity. The first rolling element 13 is disposed within the rolling element mounting cavity. The first rolling element 13 can support the lens 20 and rolls within the rolling element mounting cavity and moves along the second direction Y during the focusing process of the lens 20, limiting the movement direction of the lens 20 and providing guidance, support, and positioning. The second rolling element 14 is disposed within the second base mounting groove 111b, can support the lens 20, and rolls at least within the second base mounting groove 111b during the focusing process of the lens 20.

[0051] The carrier reinforcement 122 can be made of steel, stainless steel, alloy, etc., and this application embodiment is not limited to this. At least a portion of the carrier reinforcement 122 is embedded inside the carrier body 121 to enhance the overall structural strength of the carrier body 121.

[0052] Both the first rolling element 13 and the second rolling element 14 can be spherical, cylindrical, hollow cylindrical, elliptical, or other similar structures. They can be rolling balls or rolling shafts, and this embodiment is not limited in this respect. The materials of the first rolling element 13 and the second rolling element 14 can also be ceramic, steel, stainless steel, alloy, or other similar materials. The first rolling element 13 and the second rolling element 14 can work together with the carrier to provide support for the lens 20 and the carrier, improving the load-bearing capacity and strength. They can also provide precise guidance during the focusing process of the lens 20, ensuring the stability and reliability of focusing.

[0053] The base body 111 and base reinforcement 112, as well as the carrier body 121 and carrier reinforcement 122, can all be combined through a post-embedding injection molding process to form an integrated structure. They can also be connected using fasteners or welding, thereby improving the overall strength of the base and carrier. Furthermore, this support device only has a base, carrier, first rolling element 13, and second rolling element 14, simplifying the support structure and assembly steps, while simultaneously improving the movement accuracy of the lens 20. The first rolling element 13 and second rolling element 14 are positioned between the base and the carrier, providing support and guidance for the carrier's movement. They can achieve point contact and reduce the contact area between the carrier and the base. The rolling guide support scheme of the first rolling element 13 and second rolling element 14 in the mounting groove helps reduce friction and improve movement stability.

[0054] It should be noted that the second direction in this embodiment can be parallel to the focusing movement direction of the lens 20, that is... Figure 2 In the Y direction, the first direction X can be set to intersect with the second direction Y, for example, to be set perpendicularly, that is... Figure 2 The X direction, or the distribution at an angle to each other.

[0055] During assembly, a base body 111 with the base reinforcement 112 embedded in it can be formed by injection molding, and a carrier body 121 with the carrier reinforcement 122 embedded in it can be formed by injection molding. The base body 111 is cast to form a first mounting groove and a second mounting groove, respectively, and the carrier body 121 is cast to form a carrier mounting groove 121a. The carrier body 121 supports the second rolling element 14. The first rolling element 13 is placed in the rolling element mounting cavity formed by the carrier mounting groove 121a and the first base mounting groove 111a, and the second rolling element 14 is placed in the second base mounting groove 111b. Afterward, the lens 20 is assembled.

[0056] The periscope motor support device 10 in this embodiment has fewer components and a simpler manufacturing process. Reinforcing members are embedded inside the injection-molded parts of the carrier 12 and base 11, increasing the overall strength of the plastic parts. The base 11 and carrier 12 have mounting grooves on the same side, which restrict the movement direction of the first rolling element 13. The base has a second base mounting groove 111b, within which a second rolling element 14 is installed. Together with the first rolling element 13, it provides support and guidance, reducing friction during carrier movement, ensuring higher focusing accuracy, and making lens 20 movement more convenient and effortless.

[0057] like Figure 5 , Figure 6 As shown. In one specific embodiment, the carrier reinforcement 122 includes two carrier mounting portions 1221 and a carrier connecting portion 1222, wherein the two carrier mounting portions 1221 are disposed opposite to each other along a first direction X, and the carrier connecting portion 1222 can be connected between the two carrier mounting portions 1221 along the first direction X.

[0058] Continue to refer to Figure 5 Two carrier mounting portions 1221 are embedded in the carrier body 121 along the third direction Z. A carrier connecting portion 1222 is connected to the lower part of the carrier mounting portion 1221 and correspondingly disposed at the bottom of the carrier mounting portion 1221. A carrier reinforcing member 122 is used to at least increase the strength of the sides and bottom of the carrier body 121. A carrier mounting groove 121a is disposed on the bottom surface of the carrier body 121. The third direction Z can be related to the first direction X and the second direction Y; for example, the three directions can be arranged perpendicular to each other. Figure 5 For example, a third party can provide Z with Figure 5 The vertical direction in the middle.

[0059] The two carrier mounting parts 1221 may be, but are not limited to, plate-shaped, strip-shaped, block-shaped, etc., and the carrier connecting part 1222 may also be, but are not limited to, plate-shaped, strip-shaped, block-shaped, etc. The two carrier mounting parts 1221 and the carrier connecting part 1222 are connected to form an integral structure. The base reinforcement 112 may be made of metal, such as cast iron, steel, stainless steel, alloy, etc., to increase the overall strength of the base.

[0060] The carrier reinforcement 122 can be plate-shaped, strip-shaped, block-shaped, etc., and can be made of metal, such as cast iron, steel, stainless steel, alloy, etc., to increase the overall strength of the carrier. The carrier reinforcement 122 is disposed at the bottom of the carrier body 121, and the carrier reinforcement 122 can at least increase the bottom strength of the carrier body 121, thereby increasing the overall strength of the carrier. The carrier mounting groove 121a is disposed along the second direction Y on the bottom surface of the carrier body 121 facing the base reinforcement 112.

[0061] In this embodiment, the carrier mounting part 1221 is embedded in the interior of the carrier body 121 in the third direction Z, and the carrier reinforcement 122 is embedded in the bottom of the carrier body 121 in the first direction X. It can be formed by injection molding to form a unified whole, thereby ensuring the overall connection strength and reducing assembly errors.

[0062] In one specific embodiment, a mounting member 1223 is fixedly provided on the outer wall surface of the carrier mounting portion 1221. The mounting member 1223 extends along the second direction Y and is disposed on one side of the second base mounting groove 111b and corresponding to the second base mounting groove 111b. The mounting member 1223 can be plate-shaped, block-shaped, strip-shaped, etc., and has a guide surface on the side facing the second rolling body 14 for guiding the second rolling body 14. A rolling space for the second rolling body 14 is formed between the second base mounting groove 111b, the mounting member 1223, and the carrier reinforcement member 122. The outer peripheral surface of the second rolling body 14 is in contact with the mounting member 1223 and the carrier reinforcement member 122.

[0063] With this configuration, when the carrier 12 rolls and / or moves along the rolling element mounting cavity via the first rolling element 13 and thus moves relative to the base, the second rolling element 14 contacts the mounting member 1223 and the carrier reinforcement member 122 to ensure stability during movement. Furthermore, the surface of the second rolling element 14 that contacts the base 11 and the carrier 12 is a metal surface, which can reduce friction, making the movement of the carrier 12 smoother, reducing wear, and extending service life.

[0064] Furthermore, the outer peripheral surface of the first rolling element 13 presses against the carrier connection portion 1222 and the base reinforcement 112 respectively. Since the surface of the first rolling element 13 that contacts the base 11 and the carrier 12 is a metal surface, the friction can be further reduced, ensuring the smooth movement of the carrier 12.

[0065] Furthermore, the first base mounting groove 111a, the second base mounting groove 111b, and the carrier mounting groove 121a are all groove structures with smooth surfaces to reduce the contact friction between the first rolling element 13 and the second rolling element 14, making the movement smoother.

[0066] In one specific embodiment, the carrier mounting groove 121a is distributed on the bottom surface of the carrier body 121 and connects the two walls of the carrier body 121 along the second direction Y, that is, it spans the bottom surface of the carrier body 121 along the second direction Y, thereby increasing the travel range of the carrier and providing rolling support for the movement of the carrier 12 to the maximum extent, thus meeting the movement requirements of large stroke.

[0067] Regarding the specific structure of the first base mounting groove 111a, in one specific embodiment, it includes a first limiting surface 1111 and a second limiting surface 1112. The second limiting surface 1112 is connected to the first limiting surface 1111. The two can be directly connected or connected through a connecting surface. Correspondingly, the carrier mounting groove 121a includes a third limiting surface 1211 and a fourth limiting surface 1212. The outer peripheral surface of the first rolling element 13 abuts against the first limiting surface 1111, the second limiting surface 1112, the third limiting surface 1211, and the fourth limiting surface 1212. The first rolling element 13 is limited by each limiting surface, thereby ensuring the movement accuracy of the first rolling element 13.

[0068] For example, both the first limiting surface 1111 and the second limiting surface 1112 are obliquely distributed from the bottom of the base 11 towards the interior of the base, and the first limiting surface 1111 and the second limiting surface 1112 are directly connected to form an inverted V-shaped cross-section groove. Correspondingly, the third limiting surface 1211 and the fourth limiting surface 1212 are connected to form a V-shaped cross-section groove, and the inverted V-shaped cross-section groove and the V-shaped cross-section groove form the aforementioned rolling element mounting cavity. This reduces the limiting space and further ensures the movement accuracy of the first rolling element 13.

[0069] Furthermore, the first base mounting groove 111a and the carrier mounting groove 121a can also be inverted trapezoidal grooves, U-grooves, etc., and the second base mounting groove 111b can also be inverted trapezoidal grooves, U-grooves, etc., and this application embodiment is not limited in this respect. The second base mounting groove 111b can be a rectangular groove or a square groove, and the second rolling body 14 is disposed in the second base mounting groove 111b, limiting it to roll within the second base mounting groove 111b.

[0070] Optionally, the first rolling element 13 is a ball, the second rolling element 14 is a roller, there are two first rolling elements 13, the two first rolling elements 13 are arranged at intervals in the second direction Y, and the two can be limited by a limiting plate to maintain the interval distribution, and the second rolling element 14 is disposed between the two first rolling elements 13.

[0071] This arrangement facilitates the movement and rolling of the first rolling element 13 along the rolling element mounting cavity, and the rolling of the second rolling element 14 along the second base mounting groove 111b. The two first rolling elements 13 are arranged in a triangular configuration, which ensures greater stability of the carrier during movement.

[0072] Therefore, this embodiment employs a rolling support structure where balls and rollers are positioned within V-grooves and channels. The base V-grooves and carrier V-grooves restrict the movement direction of the balls. The rollers are located within the carrier mounting groove 121a and contact the carrier reinforcement 122 to reduce frictional losses. The triangular distribution structure of the balls and rollers ensures the reliability and stability of the carrier structure during movement.

[0073] The first base mounting groove 111a and the second base mounting groove 111b can be distributed along the first direction X on both sides of the bottom surface of the base. Optionally, the vertical distances between the first base mounting groove 111a and the second base mounting groove 111b and the central longitudinal section of the base body 111 are equal. This achieves a symmetrical distribution of the two mounting grooves, further ensuring the stability of the carrier movement.

[0074] In addition, this application embodiment also provides an optical imaging device 100, including the periscope motor support device 10 described above. For the specific structure of the periscope motor support device 10, please refer to the above.

[0075] The optical camera device 100 provided in this application produces clear images with good image quality stability.

[0076] The periscope motor support device and optical imaging equipment provided in this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
