[0051] The present application is described in detail below in conjunction with specific embodiments. It should be emphasized that the following description is merely illustrative and is not intended to limit the scope of the present application and its application.

[0052] It should be noted that, unless otherwise expressly specified and limited, the terms "center", "longitudinal", "lateral", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. used in this specification indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. Terms such as "installed", "connected", "connected", "fixed" and the like 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 mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated; therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; "multiple" means two or more; "and / or" includes any and all combinations of one or more related listed items. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] The "bayonet connection mechanism" refers to a connection structure between the lens and the camera body, in which the force exerted by the engagement between the claw and the claw engaging member enables the lens to be held on the camera body. In a typical lens installation process, the lens may first be brought into contact with the camera body, so that the claw enters the connection slot through the notch formed between the claw engaging members. The lens is then controlled to rotate in a predetermined direction (e.g., clockwise) around the optical axis, so that the claw of the lens engages with the connection slot on the camera body, allowing the lens to be held by the camera body.

[0054] The applicant discovered during the research of the present application that the claw of the lens and the notch provided by the body are usually of roughly the same size. This requires the user to accurately maintain the corresponding relationship between the two during the installation process. This brings many inconveniences to the quick installation. On the other hand, during the installation of the lens, the lens claw and the claw engaging part are prone to collision with each other, resulting in the generation of debris or particles. The entry of these particles can easily have an adverse effect on the use and operation of the components inside the body and the lens.

[0055] In addition, when the lens is held on the camera body only by the force of the bayonet connection mechanism, the gap along the optical axis cannot be eliminated, and such gap will cause the lens to shake relative to the camera body. Especially when the installed lens is large in size, shaking is more likely to occur.

[0056] Therefore, the image acquisition device provided by the embodiment of the present application provides a connection structure setting with greater installation redundancy, capable of eliminating axial clearance and / or completing the lens state with one-handed operation to overcome at least some of the above negative effects.

[0057] Figure 1 This is a schematic diagram of the structure of the image acquisition device provided in the embodiment of the present application. Figure 1 As shown, the image acquisition device can mainly include a lens 10 and a body 20. It has the function of lens replacement, and the lens 10 with a clamping claw can be detachably assembled on the body by rotating.

[0058] In this article, the components on the fuselage 20 related to the detachable installation of the lens (for example, the base member and the claw engaging member) can be referred to as a "lens mounting module". In some embodiments, the lens mounting module can be a structure integrally formed with the fuselage, and is an inseparable structural part of the fuselage. In other embodiments, the lens mounting module can also be an independent annular component 20A, which is fixed to the fuselage body 20B through a suitable connection structure (for example, a bayonet connection mechanism). In this way, the lens mounting module that is detachable from the fuselage body can provide greater flexibility for easy replacement.

[0059] Figure 2 A schematic diagram of the structure of the bayonet connection mechanism provided in the embodiment of the present application. In the present application, for the convenience of description, the bayonet connection mechanism is divided into two parts, the "claw" and the "claw engagement member" arranged opposite to each other. Although, Figure 2 In the example, the claw is set on the lens and the claw engaging member is set on the body. However, those skilled in the art can understand that the positions of the "claw" and the "claw engaging member" can be replaced according to the actual needs, and are not limited to those shown in the drawings of the present application specification.

[0060] like Figure 2 As shown, a plurality of claws 11 may be provided. These claws 11 are arranged at intervals around the optical axis X. The optical axis refers to the camera optical axis that is substantially consistent with the central axis of the lens. Specifically, the claws 11 may be arc-shaped, with a specific thickness and arc length.

[0061] Figure 3 This is a schematic diagram of the structure of the fuselage provided in the embodiment of the present application. Figure 3 As shown, the claw engaging member 21 forms a connecting groove A1 surrounding the optical axis. The connecting groove is provided with groove notches A2 corresponding to the number of the claws 11. Specifically, the claw engaging member 21 can be an annular structure. Its inner peripheral wall is formed with a plurality of arc-shaped claw abutting portions A3 along the circumferential direction, thereby forming the aforementioned connecting groove A1 and groove notches A2.

[0062] The connecting slot A1 may be a gap between the claw abutment portion A3 and the first mounting surface of the base member. The slot notch A2 is a gap formed by the cooperation of two adjacent claw abutment portions A3 and the notch arc surface A4. It is understandable that the notch arc surface A4 refers to the inner peripheral wall of the claw engagement member 21 located between the two adjacent claw abutment portions A3.

[0063] In the actual lens installation process, Figure 4 As shown, the user can move the lens 10 along the direction x1 in the figure, close to the body so that the claw 11 enters the connecting slot A1 through the slot notch A2.

[0064] Then, the user can rotate the lens 10 to rotate it around the optical axis to a specific angle along a predetermined locking direction r1. The claw 11 will rotate in the connecting slot A1 accordingly with the rotation of the lens 10, and then abut against the claw abutting portion A3, so that the lens 10 is retained on the body 20.

[0065] During the actual lens disassembly process, please continue to refer to Figure 4 , the user can rotate the lens 10 around the optical axis in a predetermined unlocking direction r2 (for example, a rotation direction opposite to the locking direction) by a certain angle. The claw 11 will rotate in the connecting slot A1 accordingly with the rotation of the lens 10, and gradually stop engaging with the claw abutment portion A3 until it reaches a position aligned with the slot notch A2.

[0066] Subsequently, without the obstruction of the claw abutment, the user can move the lens 10 out of the lens mounting module of the body along the direction x2 in the figure, and the claw 11 also correspondingly leaves the connection slot A1 through the slot notch A2.

[0067] In this application, if Figure 5As shown in FIG. 1 , the size of the claw 11 is set to be significantly smaller than the slot notch A2. “Significant” means that the size difference between the two meets the preset standard, thus distinguishing it from the traditional “roughly equivalent”. The size can be expressed in any suitable type according to the actual needs. For example, Figure 5 As shown, when both the clamping claw and the clamping slot are substantially arc-shaped, the size of the clamping claw can be represented by the arc length L1, and the size of the clamping slot can be represented by the arc length L2.

[0068] The preset standard is a numerical value or percentage set by the technician, and is not specifically limited here. It only needs to be able to be clearly distinguished from the situation in which the size of the claw and the slot gap is roughly the same in the traditional bayonet structure design. Figure 5 As shown, the arc length L2 is significantly greater than the arc length L1. Specifically, the size range of the aforementioned claws can be: expressed by the center angle of the arc claw, π / 36 to 7π / 12. Correspondingly, the size range of the aforementioned slot gap is: expressed by the center angle of the arc slot gap: π / 18 to 11π / 18.

[0069] The specific size design between the claw 11 and the slot notch A2 can provide greater redundancy for the lens installation process, and the user does not need to accurately control the lens position to ensure that the claw is aligned with the slot notch. During the lens installation and removal process, the claw is not likely to collide with the claw abutment when passing through the slot notch, which effectively improves the user experience of lens installation and removal.

[0070] In this article, for the convenience of description and distinction, on the one hand, when the claw is aligned with the notch of the card slot and can smoothly enter or exit the connection card slot through the notch of the card slot, the relative rotation angle between the lens and the body is called the "first angle range". On the other hand, when the claw and the claw abutment part abut each other, the relative rotation angle between the lens and the body is called the "second angle range". In other words, the user can complete the installation and removal operation of the lens relative to the body by rotating the lens to switch between the first angle range and the second angle range.

[0071] It should be noted that the “angle range” may be understood as a specific angle value, or may be a range value formed when the specific angle data deviates from a certain proportion.

[0072] In some embodiments, please refer to Figure 2 The image acquisition device may further include: an anti-fool component. The anti-fool component may be composed of an anti-fool card slot notch and an anti-fool component.

[0073] The foolproof member 12 may be disposed at a position close to the arc-shaped end of one of the claws 11. In this document, the claw may be referred to as a "foolproof claw". The foolproof member 12 has a specific structural design so that it is more protruding than the foolproof claw in at least one direction. For example, Figure 6 As shown, the foolproof member 12 may be a columnar member having a certain length, and is more protruding in the radial direction relative to the foolproof claw 11 .

[0074] Please refer to the corresponding Figure 5 The foolproof card slot notch A21 is one of the multiple card slot notches A2. The foolproof card slot notch A21 has an additional foolproof space relative to other card slot notches so that the foolproof component 12 can enter.

[0075] Specifically, Figure 6 As shown, the fool-proof card slot notch A21 can form the fool-proof space by setting a notch arc surface A41 that is more recessed inwardly than the non-fool-proof card slot notch, so that the fool-proof component 12 can enter smoothly.

[0076] The cooperation between the foolproof component and the foolproof slot notch can serve as a reminder and help positioning, so that the foolproof claw can only enter the connecting slot through the corresponding foolproof slot notch. Other non-foolproof slot notches will be blocked by the foolproof component because there is no foolproof space, and the foolproof claw cannot enter.

[0077] Furthermore, the foolproof member 12 can also limit the maximum rotation angle of the lens relative to the body. Figure 6 A limit end surface B1 is provided at the arc-shaped end of the claw contact portion forming the foolproof slot notch A21. When the relative rotation angle between the lens and the body is in the second angle range, the foolproof member 12 will contact the limit end surface B1, thereby limiting the lens from continuing to rotate around the optical axis in the first direction, so that it cannot exceed the second angle range.

[0078] In some embodiments, Fig. 9 As shown, the image acquisition device may further include: a plurality of first positioning components 30A. The plurality of first positioning components 30A are arranged at intervals around the optical axis.

[0079] like Fig. 9 and Fig.10 As shown, each of the first positioning components 30A includes: a first receiving cavity 32 , a positioning component 34 and a positioning recess 36 .

[0080] The first receiving cavity 32 can be arranged on the body or the lens. In the drawings of the present application specification, the first receiving cavity 32 is arranged on the lens as an example for display. It can be any suitable type of cavity opened along the optical axis, as long as it can provide enough accommodation space.

[0081] The positioning member 34 is assembled in the first receiving cavity 32 and is a movable member that can move relative to the first receiving cavity. The positioning recess 36 is a portion disposed opposite to the positioning member and has a shape that matches the portion of the positioning member protruding from the first receiving cavity.

[0082] In this article, the term "opposite arrangement" is used to indicate that two components have a corresponding matching relationship and are arranged on two relatively independent components. Fig. 9 As shown, in the case where the positioning component 34 is disposed on the lens, the positioning recess 36 can be disposed at a corresponding position of the lens mounting module.

[0083] In actual use, when the relative rotation angle between the lens and the body is within the second angle range, the portion of the positioning component protruding from the first receiving cavity will be restricted and received in the positioning recess to eliminate the gap between the two, thereby preventing the lens from shaking relative to the body.

[0084] Specifically, Fig.10 As shown, the aforementioned first positioning assembly 30A may further include a first elastic component 38. The positioning recess 36 is a spherical recess, and the positioning component is a spherical component. Thus, the two cooperate with each other to provide a contact surface inclined to the optical axis, so that the first positioning assembly 30A does not impose unnecessary restrictions on the relative rotation between the lens and the body.

[0085] In actual use, when the lens rotates relative to the body about the optical axis in the second direction, the contact surface between the positioning recess 36 and the positioning component 34 is inclined. Therefore, the driving force of the relative rotation of the lens can form a part of the force that drives the first elastic component to deform, so that the part of the positioning component 34 protruding from the first receiving cavity 32 is squeezed and retracted into the first receiving cavity 32, and no unnecessary restriction is imposed on the rotation of the lens.

[0086] In other embodiments, Figure 7 As shown, the image acquisition device may further include: a second positioning component 30B. The second positioning component is arranged between the lens and the body, and is also used to limit the shaking of the lens relative to the body by eliminating the gap when the relative rotation angle between the lens and the lens mounting module is in the second angle range.

[0087] Specifically, Figure 7As shown, the second positioning assembly 30B includes: an annular positioning cylinder 31 and an annular positioning step 33 .

[0088] The annular positioning cylinder 31 and the annular positioning step 33 can both be annular components arranged around the optical axis. The two have matching sizes and can be arranged on the lens and the lens mounting module respectively. Figure 7 As shown, the annular positioning cylinder 31 can be arranged on the lens, and the annular positioning step 33 is located on the lens mounting module.

[0089] In actual use, Figure 8 As shown, when the claw 11 enters the connecting slot A1 through the slot notch A2, the annular positioning cylinder 31 can engage with the annular positioning step 33, thereby eliminating the gap and limiting the shaking of the lens relative to the body.

[0090] It should be noted that there is no mutually exclusive relationship between the first positioning component 30A and the second positioning component 30B described above, and both can be applied to the same embodiment at the same time and cooperate with each other to better avoid the lens from shaking relative to the body.

[0091] In some embodiments, Fig. 9 As shown, the image acquisition device may further include a locking component 40. The locking component 40 is disposed between the lens and the body, and is used to limit the relative rotation between the lens and the body when the relative rotation angle between the lens and the lens mounting module is within a second angle range.

[0092] Specifically, Fig.10 and Fig.11 As shown, the locking assembly 40 includes: a locking component 41 , a second receiving cavity 42 , a second elastic component 43 and a locking hole 44 .

[0093] The second receiving cavity 42 can be arranged on the lens or the lens mounting module. In the drawings of the present application specification, the second receiving cavity 42 is arranged on the lens as an example for display. It can be any suitable type of cavity as long as it can provide enough accommodation space.

[0094] The locking component 41 is assembled in the second receiving cavity 42 and is a movable component that can move relative to the second receiving cavity. The second elastic component 43 is arranged between the locking component 41 and the second receiving cavity 42. The second elastic component 43 can provide elastic force for the locking component so that at least a part of the locking component 41 protrudes out of the second receiving cavity 42. For example, the second elastic component 43 can be a coil spring, and the two ends of the second elastic component 43 are respectively abutted against the bottom of the locking component and the second receiving cavity, thereby driving the locking component to protrude out of the second receiving cavity.

[0095] The locking hole 44 is a portion disposed opposite to the locking component 41, and has a shape that matches the portion of the locking component protruding from the second receiving cavity. In this article, the term "oppositely disposed" is used to indicate that two components have a corresponding matching relationship and are allocated and disposed on two relatively independent components. For example, in the case where the locking component 41 is disposed on the lens, the locking hole 44 can be disposed at a corresponding position of the lens mounting module.

[0096] In actual use, when the relative rotation angle between the lens and the lens mounting module is within the second angle range, the portion of the locking component 41 protruding outside the second receiving cavity will be restricted and received in the locking hole 44, thereby limiting the rotation of the lens.

[0097] Furthermore, if Fig.10 As shown, the locking assembly may further include: an unlocking component 45. At least a portion of the unlocking component 45 is exposed on the outer surface of the lens, and is a movable component that can move relative to the lens. Preferably, the portion of the unlocking component 45 exposed on the outer surface of the lens can be designed as a friction surface or other similar surfaces to facilitate the user's force application.

[0098] There is a linkage relationship between the unlocking component 45 and the locking component 41. "Linkage" means that the movements of the two components are related, and the movement of one component can drive the corresponding movement of the other component. This can be achieved in any suitable way, for example, Figure 4 As shown, the unlocking member 45 is simply rigidly connected to the locking member 41 .

[0099] In actual use, the user can simply move the unlocking component 45 exposed on the outer surface of the lens to drive the locking component 41 to move toward the second receiving cavity until the locking component is completely received in the second receiving cavity. As a result, the locking component 41 and the locking hole 44 are separated from each other, and no longer restrict the rotation of the lens. Subsequently, the user can rotate the lens to rotate it relative to the body around the optical axis along the second direction to the first angle range, and remove the lens from the body.

[0100] In the image acquisition device provided in the embodiment of the present application, the unlocking component has a reasonable layout position, and the user can conveniently complete the unlocking and rotating lens disassembly operations with one hand, which is conducive to improving the convenience of lens disassembly and can greatly improve the user experience.

[0101] In order to fully describe the specific structural design of the image acquisition device in the embodiment of the present application, the structures of the lens and the lens mounting module are described in detail below to describe the matching relationship between the two.

[0102] Fig.11A schematic diagram of the structure of a lens mounting module provided in an embodiment of the present application. Fig.12 A schematic diagram of the structure of a lens provided in an embodiment of the present application. Fig.11 The lens with the claws shown can be relative to Fig.12 The lens mounting module shown has a connecting card slot for loading and unloading, and vice versa.

[0103] On the one hand, if Fig.11 As shown, the lens mounting module includes: a claw engaging component 21 and a base component 22.

[0104] The base member 22 is annular and has a first mounting surface and a second mounting surface that are opposite to each other. In this embodiment, the first mounting surface S1 is a surface that is connected to the lens, and the second mounting surface S2 is a surface that is connected to the body. It should be noted that the mounting surface is not limited to describing a specific plane in solid geometry, but is used to represent surfaces with the same orientation.

[0105] The claw engaging member 21 is arranged on the first mounting surface and can cooperate with the base member 22 to form a connecting slot A1 arranged along the circumferential direction. The connecting slot A1 is provided with a plurality of slot notches A2 along the circumferential direction. The claw 11 of the lens can enter the connecting slot through the slot notches A2 and engage with the claw engaging member 21 after rotation, so that the lens is retained on the body.

[0106] Please continue reading Fig.11 The claw engaging member 21 is mainly composed of two parts: a engaging body A0 and a plurality of claw abutting parts A3.

[0107] The joint body A0 is annular and located on the first mounting surface. A plurality of claw abutting portions A3 are formed on the inner peripheral wall of the joint body A0 and have a bearing surface and a joint surface that are separated from each other.

[0108] The engaging surface S3 of the claw abutting portion cooperates with the inner peripheral wall of the engaging body to form an annular positioning step 33. The supporting surface S4 of the claw abutting portion abuts against the claw 11 that enters the connecting slot and rotates to a specific angle.

[0109] Furthermore, the claw abutment portion A3 is an arc-shaped structure. The arc-shaped ends B2 opposite to the adjacent claw abutment portions cooperate with the notch arc surface A4 to form the aforementioned slot notch A2. The notch arc surface A4 refers to the inner peripheral wall of the joint body located between the adjacent claw abutment portions.

[0110] At least one of the slot notches can be set as a foolproof slot notch, and the rest can be called non-foolproof slot notches. The foolproof slot notch has an additional foolproof space relative to other non-foolproof slot notches. The foolproof space can be formed by a notch arc surface that is more inwardly concave relative to the notch arc surface of other non-foolproof slot notches.

[0111] In addition, the first mounting surface of the base member 22 may be provided with a plurality of positioning recesses 36 and at least one locking hole 44. The plurality of positioning recesses 36 may be arranged at intervals around the optical axis, and the arrangement position of the locking hole 44 is not particularly limited.

[0112] On the other hand, Fig.12 As shown, the lens 10 may include: a plurality of claws 11 and a lens barrel 13 .

[0113] The lens barrel 13 is a cylindrical main structure, in which a plurality of optical components (e.g., a combination of multiple lenses) are housed and fixed. One end of the lens barrel is a lens end that can collect light, and the other end can be called a "third mounting surface" that is engaged with a lens mounting module. A plurality of claws 11 are arranged at intervals on the third mounting surface along the circumferential direction of the lens barrel.

[0114] As mentioned above, the size of the claw can be set according to the notch of the slot (or vice versa), and the size difference between the two meets the preset standard to provide greater installation redundancy. The claw 11 can also be arc-shaped, with two arc-shaped ends away from each other.

[0115] Furthermore, the lens barrel 13 is also provided with an annular positioning cylinder 31. The annular positioning cylinder 31 may be a component located at the edge of the lens barrel and arranged around the circumference of the lens barrel. The annular positioning cylinder 31 and the annular positioning step 33 are mutually cooperating components. The two are arranged at a suitable position so that the lens and the lens mounting module can be brought into contact with each other and the claws of the lens enter the connecting slot and engage with each other.

[0116] Furthermore, the lens barrel 13 is also provided with an anti-foolproof member 12. Figure 8 The foolproof member 12 is arranged near or close to the arc-shaped end of one of the claws 11, and is more protruding than the claw 12 in the radial direction of the lens barrel. Therefore, the claw close to the foolproof member 12 can only enter the connecting slot A1 through the foolproof slot notch A21, but cannot pass through other slot notches A2, so as to achieve the foolproof effect of ensuring the correct alignment of the claw and the slot notch.

[0117] In addition, the lens can also include a plurality of positioning members and locking members. A plurality of positioning members are arranged at intervals around the optical axis. Accordingly, the third mounting surface of the lens barrel 13 is provided with a first receiving cavity 32 and a second receiving cavity 42, which are respectively used to accommodate the aforementioned positioning members and locking members.

[0118] In some embodiments, please refer to Fig.12 The positioning component may include: a first receiving cavity 32 , a positioning component 34 and a first elastic component 36 .

[0119] The positioning member 34 may be assembled in the first receiving cavity and may move relative to the first receiving cavity. The first elastic member 36 may be a compression spring, which is disposed between the positioning member 34 and the first receiving cavity 32, so as to provide an elastic force capable of driving the positioning member 34 to protrude from the first receiving cavity 32. Alternatively, the first elastic member 36 may also be other suitable elastic members, as long as the positioning member 34 can maintain a state of partially protruding from the first receiving cavity 32 without the influence of external force.

[0120] For further information, please refer to Fig.12 The locking component may include: a locking component 41, a second receiving cavity 42, a second elastic component 43 and an unlocking component 45.

[0121] The locking component 41 is assembled in the second receiving cavity 42 and can move relative to the second receiving cavity. The second elastic component 42 is arranged between the locking component 41 and the second receiving cavity 43, and can provide an elastic force to drive the locking component 41 to protrude from the second receiving cavity 42. In other words, with the support of the second elastic component, the locking component 41 will maintain a state where at least a portion of it protrudes from the second receiving cavity 42 when there is no external force. Alternatively, the second elastic component can also be selected to use any suitable type of elastic structure that can provide the same function according to the actual needs.

[0122] The unlocking component 45 is a movable component that can move relative to the lens barrel. At least a portion of the unlocking component 45 is exposed on the outer surface of the lens barrel for the user to move it. The unlocking component 45 is linked to the locking component 41 (for example, the two are rigidly connected), and the unlocking component 45 can be moved to drive the locking component to overcome the elastic force provided by the second elastic component, so that the locking component is completely recovered into the second receiving cavity 42.

[0123] The mutual coordination relationship between the lens and the various structural components in the lens mounting module can be referred to the relevant description in the above-mentioned image acquisition device embodiment, and will not be repeated here. It should be noted that one or more structural components disclosed in the above embodiments can be reduced or added accordingly according to the needs of actual conditions to provide corresponding functions or technical effects. There is no mutual exclusion or association between the above structural components, and they can be used in any combination to form multiple different embodiments.

[0124] The above contents are further detailed descriptions of the present application in combination with specific / preferred implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the scope of protection of the present application.
