[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work 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 meanings as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

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

[0037] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements.

It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0039] At present, in the field of periscope motors, the bearing structure plays a decisive role. In order to enable the lens to move smoothly when focusing, a bearing structure that can provide efficient support and reduce friction is required. However, the existing periscope motor bearing structures, such as spring-type or ring-type bearing frost, although they can meet the bearing requirements, have certain limitations in terms of stability, reliability, and travel, especially long-stroke motion accuracy. Especially when there are high requirements for the movement accuracy and bearing capacity of the lens, these traditional solutions often cannot achieve the desired effect.

[0040] In order to improve the shortcomings of the existing bearing structure, the present application proposes a new support rolling solution by simplifying the structure of the periscope motor support device and optimizing the mobile support method. This solution simplifies the types and number of support components, optimizes the support movement scheme, and improves the overall strength and durability of the periscope motor. In addition, through the reasonable distribution of balls and rollers, it is ensured that the carrier has higher stability during the movement process, thereby ensuring the use effect and long service life of the periscope motor.

[0041] The term “plurality” used in this application refers to two or more (including two).

The second base mounting groove 111b is provided with a second rolling body 14, which can provide support and limit the rolling of the second rolling body 14 when the lens 20 is focused.

[0048] The first base mounting groove 111a may be a strip groove extending along the second direction Y, or a square groove or a rectangular groove. When a strip groove is used, it is convenient for the rolling body to move along the second direction Y during the focusing process of the lens 20. When a square groove or a rectangular groove is used, it is convenient for the rolling body to roll along the groove. The second base mounting groove 111b can at least provide guidance and limit for the rolling of the second rolling body 14. It can be a square groove or a rectangular groove, which provides support for the second rolling body 14 and meets the rolling requirements of the second rolling body 14. It can also be a strip groove, which is convenient for the second rolling body 14 to roll and move along the groove.

[0049] The carrier 12 is arranged in the base 11, and the carrier 12 includes a carrier body 121 and a carrier reinforcement 122.

The carrier body 121 is provided with a carrier mounting groove 121a, which is distributed along the second direction Y, and the carrier mounting groove 121a is used to adapt to the first base mounting groove 111a to form a rolling body mounting cavity.

[0050] The carrier body 121 may be a separate block or box structure with a lens mounting cavity, or a complex structure composed of separate block, box or plate structures, which is not limited in the present application. The carrier reinforcement 122 may enhance the overall structural strength of the carrier body 121. The carrier mounting groove 121a is arranged corresponding to the first base mounting groove 111a. The two mounting grooves constitute a rolling body mounting cavity. The first rolling body 13 is arranged in the rolling body mounting cavity. The first rolling body 13 can carry the lens 20, and roll in the rolling body mounting cavity and move along the second direction Y during the focusing process of the lens 20, limit the moving direction of the lens 20, and provide guidance, support and limit. The second rolling body 14 is arranged in the second base mounting groove 111b, can carry the lens 20, and roll at least in the second base mounting groove 111b during the focusing process of the lens 20.

[0051] The carrier reinforcement 122 may be made of steel, stainless steel, alloy, etc., which is not limited in the present embodiment. At least part of the carrier reinforcement 122 is embedded in the carrier body 121 to enhance the overall structural strength of the carrier body 121 .

[0052] The first rolling body 13 and the second rolling body 14 can both be spherical, cylindrical, hollow cylindrical, elliptical or other structures, and can be rolling balls or rolling shafts, which are not limited in the embodiments of the present application. The first rolling body 13 and the second rolling body 14 can also be made of ceramic, steel, stainless steel, alloy or other materials. The first rolling body 13 and the second rolling body 14 can cooperate with the carrier to provide support for the lens 20 and the carrier, improve the bearing capacity and bearing strength, and can provide precise guidance during the focusing process of the lens 20, ensuring the stability and reliability of the focusing.

[0053] The base body 111 and the base reinforcement 112, as well as the carrier body 121 and the carrier reinforcement 122, can be combined by embedding and then injection molding to form an integrated structure, and can also be connected by fasteners or welded, thereby improving the overall strength of the base and the carrier, and the support device only has a base, a carrier, a first rolling body 13 and a second rolling body 14, thereby simplifying the support structure and the assembly steps, and at the same time, improving the movement accuracy of the lens 20. The first rolling body 13 and the second rolling body 14 are arranged between the base and the carrier to provide support and guidance for the movement of the carrier, can achieve point contact, and reduce the contact area between the carrier and the base, and the rolling guide support scheme of the first rolling body 13 and the second rolling body 14 in the mounting groove is convenient for reducing friction and improving the stability of movement.

[0054] It should be noted that the second direction in the embodiment of the present application may be parallel to the focus movement direction of the lens 20, that is, Figure 2 The first direction X may intersect with the second direction Y, for example, vertically. Figure 2 The X direction, or the distribution at an angle to each other.

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

[0056] The periscope motor support device 10 in the embodiment of the present application has a small number of parts and a simple process. The carrier 12 and the base 11 are embedded with reinforcements inside the injection molded parts to increase the overall strength of the plastic parts. The base 11 and the carrier 12 have a mounting groove structure on the same side to limit the moving direction of the first rolling body 13. The base is provided with a second base mounting groove 111b, and a second rolling body 14 is provided in the groove to provide support and guidance together with the first rolling body 13, reduce the friction force when the carrier moves, ensure higher focusing accuracy, and make the movement of the lens 20 more convenient and labor-saving.

[0057] like Figure 5 , Figure 6 In a specific embodiment, the carrier reinforcement member 122 includes two carrier mounting portions 1221 and a carrier connecting portion 1222 , wherein the two carrier mounting portions 1221 are arranged 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 Figure 5 The two carrier mounting parts 1221 are embedded in the carrier body 121 along the third direction Z, the carrier connecting part 1222 is connected to the lower part of the carrier mounting part 1221, and is correspondingly arranged at the bottom of the carrier mounting part 1221, the carrier reinforcing member 122 is used to at least increase the strength of the side and bottom of the carrier body 121, and the carrier mounting groove 121a is arranged 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, the third direction Z can be Figure 5 The vertical direction in .

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

[0060] The carrier reinforcement member 122 may be in the shape of a plate, strip, block, etc., and may be made of metal, such as cast iron, steel, stainless steel, alloy, etc., to increase the overall strength of the carrier. The carrier reinforcement member 122 is disposed at the bottom of the carrier body 121, and the carrier reinforcement member 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 member 112.

[0061] In this embodiment, the carrier mounting portion 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 a specific embodiment, a mounting member 1223 is fixedly provided on the outer wall surface of the carrier mounting portion 1221, and the mounting member 1223 extends along the second direction Y. The mounting member 1223 is arranged on one side of the second base mounting groove 111b and is arranged 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, which can guide 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, and the outer peripheral surface of the second rolling body 14 is attached to the mounting member 1223 and the carrier reinforcement member 122.

[0063] In this way, when the carrier 12 rolls and / or moves along the rolling body mounting cavity through the first rolling body 13 and thereby moves relative to the base, the second rolling body 14 contacts the mounting member 1223 and the carrier reinforcement 122 to ensure stability during movement, and the surface of the second rolling body 14 in contact with the base 11 and the carrier 12 is a metal surface, which can reduce friction, make the carrier 12 move more smoothly, reduce wear, and extend the service life.

[0064] Furthermore, the outer peripheral surface of the first rolling body 13 is pressed against the carrier connecting portion 1222 and the base reinforcement 112 respectively. Since the surfaces of the first rolling body 13 in contact with the base 11 and the carrier 12 are metal surfaces, the friction can be further reduced to ensure 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 body 13 and the second rolling body 14, making the movement smoother.

[0066] In a specific embodiment, the carrier mounting groove 121a is distributed on the bottom surface of the carrier body 121 and connects the two wall surfaces 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 with the maximum travel, thereby meeting the movement requirements of a large travel.

[0067] Regarding the specific structure of the first base mounting groove 111a, in a specific embodiment, it includes a first limiting surface 1111 and a second limiting surface 1112, and the second limiting surface 1112 is connected to the first limiting surface 1111, and 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, and the outer peripheral surface of the first rolling body 13 is pressed against the first limiting surface 1111, the second limiting surface 1112, the third limiting surface 1211 and the fourth limiting surface 1212, and the first rolling body 13 is limited by each limiting surface, thereby ensuring the movement accuracy of the first rolling body 13.

[0068] Exemplarily, the first limiting surface 1111 and the second limiting surface 1112 are both obliquely distributed from the bottom surface of the base 11 to the inside 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-sectional groove. Correspondingly, the third limiting surface 1211 and the fourth limiting surface 1212 are connected to form a V-shaped cross-sectional groove, and the inverted V-shaped cross-sectional groove and the V-shaped cross-sectional groove form the above-mentioned rolling element installation cavity. In this way, the limiting space can be reduced, and the movement accuracy of the first rolling element 13 can be further guaranteed.

[0069] In addition, the first base mounting groove 111a and the carrier mounting groove 121a can also be an inverted trapezoidal groove, a U groove, etc., and the second base mounting groove 111b can also be an inverted trapezoidal groove, a U groove, etc., which is not limited in the embodiment of the present application. The second base mounting groove 111b can be a rectangular groove or a square groove, and the second rolling body 14 is arranged in the second base mounting groove 111b, and is limited to rolling in the second base mounting groove 111b.

[0070] Optionally, the first rolling body 13 is a sphere, the second rolling body 14 is a roller, there are two first rolling bodies 13, the two first rolling bodies 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 body 14 is arranged between the two first rolling bodies 13.

[0071] This arrangement facilitates the first rolling body 13 to move and roll along the rolling body installation cavity, and the second rolling body 14 to roll along the second base installation groove 111b. The two first rolling bodies 13 and the first rolling body 13 are placed in a triangle, which can ensure that the carrier has higher stability when moving.

[0072] Therefore, the embodiment of the present application adopts a rolling support structure of balls and rollers in V-grooves and grooves. The V-grooves of the base and the carrier limit the moving direction of the balls. The rollers are located in the carrier mounting groove 121a and contact the carrier reinforcement 122 to reduce friction 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 on both sides of the bottom surface of the base along the first direction X. 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. In this way, the symmetrical distribution of the two mounting grooves is achieved, and the stability of the carrier movement is further ensured.
