Description

Technical Field

[0001] This application relates to the field of optical technology, and in particular to a lens module, a body module, and an imaging device. Background Technology

[0002] In today's camera technology field, the communication connection between a camera lens and body primarily relies on contact points on both. In traditional cameras, the layout and number of these contact points on the lens and body are usually fixed and follow specific industry standards. Most common camera brands on the market have specified lens mount contact specifications. This fixed contact design has ensured the realization of basic functions between the lens and body, such as image data transmission, lens focus control, and aperture adjustment, throughout the history of camera development.

[0003] However, with the rapid development of photography technology and the increasing demand from users for diverse camera functions, this fixed contact design has gradually revealed its significant limitations. On the one hand, fixed contacts can only support a limited range of functions and cannot meet the expansion needs of new features. For example, in current popular scenarios such as high-resolution image capture, 8K video recording, and multi-lens collaborative shooting, existing contacts cannot provide sufficient data transmission bandwidth and control signal interfaces, making it difficult for cameras to implement these complex functions. On the other hand, when camera manufacturers attempt to add new features to their cameras, the fixed number and functions of contacts make it difficult to easily connect and communicate with these new functional modules, posing a significant challenge to camera function upgrades.

[0059] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0060] To overcome the aforementioned problems, there is an urgent need in the market for a camera body or lens with expansion contacts. This body or lens needs to have good compatibility, ensuring it can be properly adapted to existing ordinary lenses or camera bodies, guaranteeing that users' existing photographic equipment can continue to be used without wasting resources; and it also needs to be able to expand its functionality through expansion contacts.

[0061] like Figure 1 As shown, this application embodiment first provides an imaging device 300, which includes a lens module 200 and a body module 100. The lens module 200 and the body module 100 are detachably connected. Specifically, the lens module 200 and the body module 100 are electrically and communicatively connected via contacts.

[0062] like Figure 8 and Figure 9 As shown, the lens module 200 includes a first chip 28, and the body module 100 includes a second chip 17. The first chip 28 and the second chip 17 are electrically and communicatively connected.

[0063] For example, the lens module 200 is connected to the body module 100 via contacts and obtains the necessary power from the battery (not shown) of the body module 100 through the second chip 17. The lens module 200 is used to collect and focus light reflected from the subject and guide the light to a photosensitive element (not shown) inside the body module 100 to form a clear optical image. Furthermore, through the contacts, the lens module 200 transmits feedback information such as aperture value and real-time focus to the second chip 17 inside the body module 100, such as... Figure 9As shown, conversely, the body module 100 sends lens control signals, such as lens rotation signals and aperture adjustment signals, to the first chip 28 of the lens module 200 via the contact points.

[0064] When the imaging device 300 is in use, the object being photographed is located in front of the operator, and the lens module 200 is located in front of the body module 100. Based on this, the forward and backward directions are defined in the imaging device 300, such as... Figure 1 As shown. Additionally, the imaging device 300 has an axis X, which refers to the optical axis direction of the lens module 200 and the body module 100; the front-to-back direction is the direction of the optical axis. Finally, in the usual operating state of the imaging device 300, the width direction of the body module 100 is horizontal. Based on the usual operating state of the imaging device 300, the up and down directions, as well as the left and right directions, are defined. The left and right directions are also the width directions of the body module 100.

[0065] In the front-to-back direction, the lens module 200 and the body module 100 are connected to form an electrical and communication connection through contacts, or the lens module 200 and the body module 100 are separated.

[0066] like Figure 5 , Figure 6 and Figure 7 As shown, the lens module 200 of this application embodiment will be introduced first.

[0067] like Figure 5 , Figure 6 and Figure 7 As shown, in an embodiment of this application, the lens module 200 includes a lens body 22 and a first standard contact group 26. The lens body 22 has a front end and a rear end, wherein the rear end of the lens body 22 has a rear end surface. It is understood that the rear end surface does not necessarily have to be planar. Figure 10 , Figure 11 and Figure 12 As shown in the embodiments of this application, the first standard contact group 26 includes a plurality of first standard contacts 261, which are disposed on the lens body 22 and exposed on the rear end surface. When the lens module 200 is connected to the body module 100, the first standard contacts 261 are used to form an electrical connection and a communication connection with the second chip 17 of the body module 100, so as to receive control signals from the second chip 17 and provide feedback signals to the second chip 17.

[0068] like Figure 1 , Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, in some embodiments of this application, the lens module 200 further includes a lens assembly 21, which is disposed on the lens body 22 and is used to collect and focus the light reflected by the subject.

[0069] like Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments of this application, the lens module 200 further includes a first extended contact group 27, which includes a plurality of first extended contacts 271. The first extended contacts 271 are disposed on the lens body 22 and exposed on the rear end face. When the lens module 200 is connected to the body module 100, the first extended contact group 27 is at least used to form an electrical connection and / or a communication connection with the second chip 17 of the body module 100. Specifically, the first extended contact group 27 forms an electrical connection with the second chip 17 of the body module 100, and the second chip 17 can provide power to the first extended contact group 27. The first extended contact group 27 forms a communication connection with the second chip 17 of the body module 100, and the first extended contacts 271 can receive control signals from the second chip 17 and provide feedback signals to the second chip 17.

[0070] The lens module 200 provided in this application embodiment has a plurality of first extension contacts 271 on its rear end surface, which provide a bayonet contact connection scheme for manufacturers to expand the functions of the imaging device 300, thereby allowing manufacturers to further expand the functions and applications on the lens module 200 or the body module 100.

[0071] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments of this application, the lens module 200 further includes at least one extended function module 29, which is disposed on the lens body 22 and connected to a plurality of first extended contacts 271 in the first extended contact group 27. Specifically, the extended function module 29 is electrically connected and / or communicatively connected to the plurality of first extended contacts 271.

[0072] Through the first extended contact 271, the extended function module 29 can form an electrical connection and / or a communication connection with the second chip 17 of the body module 100, thereby enabling the second chip 17 of the body module 100 to provide the extended function module 29 with the electrical energy required for operation, and / or to receive feedback signals from the extended function module 29 and provide control signals to the extended function module 29.

[0073] The type of the extended function module 29 is not limited. In some optional embodiments, the extended function module 29 can be a fill light, such as a flash or a constantly lit fill light; for example, the extended function module 29 can be a laser focus assist device, which emits a laser beam to form a recognizable light spot on the surface of the subject in ultra-low light or low contrast scenes (such as astrophotography or dark environment product photography) to assist the lens module 200 in focusing and improve focusing accuracy and efficiency; for another example, the extended function module 29 can be a ranging module, used to measure the distance from the lens module 200 to the subject, which can also assist the lens module 200 in focusing and improve focusing accuracy and efficiency, etc.

[0074] In some alternative embodiments, the extended functional module 29 can be a ranging module, specifically a TOF module, i.e., a Time of Flight module. A TOF module is a sensor module that uses the time-of-flight principle to measure distance or obtain depth information.

[0075] In some embodiments of this application, such as Figure 8 and Figure 9 The first chip 28 is located inside the lens body 22, and each first standard contact 261 is connected to the first chip 28. When the lens module 200 is docked with the body module 100, the first chip 28 and the second chip 17 form an electrical and communication connection. Figure 8 and Figure 9 As shown, the lens assembly 21 is connected to the first chip 28, and the second chip 17 controls the lens assembly 21 via the first chip 28 to perform focusing, adjustment, etc.

[0076] like Figure 8 As shown, in some embodiments, each first extension contact 271 is connected to the extension function module 29. Each first extension contact 271 is directly connected to the extension function module 29. The information acquired by the extension function module 29 is transmitted to the second chip 17 via the first extension contact 271, without going through the first chip 28.

[0077] like Figure 9 As shown, in some embodiments, each first extension contact 271 is connected to the first chip 28, and the extension function module 29 is connected to the first chip 28. Each first extension contact 271 is connected to the extension function module 29 via the first chip 28. The information acquired by the extension function module 29 is transmitted to the second chip 17 via the first chip 28 and the first extension contact 271.

[0078] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, in some embodiments of this application, the extended function module 29 is located at the front end of the lens body 22. That is, in the front-back direction, the extended function module 29 is positioned as far forward as possible on the lens body 22. The purpose of this arrangement is twofold: First, in the front-back direction, the distance between the extended function module 29 and the subject is smaller. For example, when the extended function module 29 emits auxiliary illumination light or auxiliary focusing light, the light intensity is higher; or, when the extended function module 29 emits light for distance measurement, the position of the extended function module 29 and the lens assembly 21 is closer, resulting in a more accurate measured distance to the subject, which is beneficial for the focus adjustment of the lens assembly 21. Second, in the vertical direction, the closer distance between the extended function module 29 and the optical axis allows the extended function module 29 to be more aligned with the subject, which is also beneficial for aligning the light with the subject and for the focus adjustment of the lens assembly 21.

[0079] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of this application, the extended function module 29 is located on the upper side of the lens body 22. The extended function module 29 is relatively fixed to the lens body 22. The purpose of this arrangement is that, in any state of use of the imaging device 300, the extended function module 29 will not obstruct the optical path of the lens assembly 21.

[0080] Furthermore, such as Figure 5 As shown, in the usual operating direction of the imaging device 300, the extended function module 29 is located above the optical axis of the lens module 200. That is, the extended function module 29 is aligned with the optical axis in the vertical direction. The lens module 200 has a symmetrical appearance.

[0081] In some embodiments of this application, such as Figures 10 to 12 As shown, the first standard contacts 261 are arranged at intervals along the first arc L1. That is, multiple first standard contacts 261 are arranged on the same circle. When the lens module 200 and the body module 100 are docked and disassembled, they need to rotate relative to each other. This is compatible with the arrangement of the first standard contacts 261 along the arc.

[0082] Based on this circle, the radial direction of the contact point is defined, such as... Figure 10 , Figure 11 and Figure 12As shown, in the radial direction of the contacts, the first extended contact group 27 is located inside the first standard contact 261. The first extended contact group 27 utilizes the space on the lens body 22 located inside the first standard contact group 26. This eliminates the need to modify the size of the lens body 22 or the position of the first standard contact group 26, thus facilitating compatibility between the lens module 200 and other types of body modules 100.

[0083] In some embodiments, such as Figures 10 to 12 As shown, multiple first extended contacts 271 are arranged at intervals along the second arc line L2. That is, multiple first extended contacts 271 are arranged on the same circle. Optionally, the centers of the first arc line L1 and the second arc line L2 coincide.

[0084] In some embodiments of this application, such as Figures 10 to 12 As shown, at least one first extended contact 271 is located between two adjacent first standard contacts 261 along the directions of the first arc L1 and the second arc L2 (the directions around the center of the first arc L1 and / or the center of the second arc L2, referring to the directions of all arcs concentric with the first arc L1). This arrangement aims to ensure that at least a portion of the first extended contact 271 corresponds to the space between two adjacent first standard contacts 261 along the directions of the first arc L1 and the second arc L2. Therefore, the first extended contact 271 can have a larger width along the direction of the first arc L1, and thus, a larger area. Correspondingly, the first extended contact 271 can have a smaller height in the radial direction of the contact, reducing the space occupied by the contact in the lens body 22 and ensuring sufficient space inside the lens body 22 for light to pass through.

[0085] Optionally, such as Figures 10 to 12 As shown, along the directions of the first arc line L1 and the second arc line L2, each of the first extended contacts 271 is located between two adjacent first standard contacts 261. Thus, the first standard contact group 26 as a whole occupies a relatively small space in the radial direction of the contacts.

[0086] In some embodiments of this application, such as Figures 10 to 12As shown, at least one first extended contact 271 is partially aligned with at least one first standard contact 261 along the direction of the first arc line L1. That is, at least one group of extended contacts extends radially into the space between two adjacent first standard contacts 261. The purpose of this arrangement is to further reduce the space occupied by the first extended contact 271 and the first standard contact 261 in the radial direction of the contact. At the same time, it is not necessary to change the spacing between the first standard contacts 261 in the direction along the first arc line L1, that is, it is not necessary to change the first standard contacts 261, which is beneficial for the adaptation of the lens module 200 to other types of body modules 100.

[0087] Optionally, such as Figure 10 , Figure 11 and Figure 12 As shown, along the direction of the first arc L1, each of the first extended contacts 271 is partially aligned with a first standard contact 261.

[0088] In some embodiments of this application, such as Figure 10 , Figure 11 and Figure 12 As shown, at least one side of at least one first extended contact 271 is provided with a clearance chamfer 2670 in the direction along the second arc L2. The purpose of this arrangement is that the width of at least one first extended contact 271 is reduced in the direction along the first arc L1, so that it is easier to insert it radially between two adjacent first standard contacts 261, thereby further reducing the space occupied by the first extended contact 271 and the first standard contact 261 in the radial direction of the contact.

[0089] In some embodiments of this application, such as Figure 10 , Figure 11 and Figure 12 As shown, in the direction along the second arc L2, at least one first extended contact 271 has a clearance chamfer 2670 on both sides. In the radially outward direction along the contact, at least one first extended contact 271 has a tapered "head" that can be inserted radially between two adjacent first standard contacts 261.

[0090] It should be noted that the "avoidance chamfer 2670" here refers to a design where the shape of the first extended contact 271 is significantly different from the shape of the first standard contact 261, with relatively inward-curving edges. For example, if there are many first standard contacts 261 and relatively few first extended contacts 271, then some first standard contacts 261 may be located near which no first extended contacts 271 are needed. These extended contacts 271 can be designed according to existing standard designs. Assuming they have a standard shape, the "avoidance chamfer 2670" refers to the shape of the first extended contact 271 being designed by removing at least one corner of the rectangle, resulting in a cone or trapezoidal "head" shape. Similarly, if the standard shape is a circle, the first extended contact 271 is designed by removing a portion of the circle, resulting in an arc shape. Other shapes will not be listed in detail.

[0091] It is understandable that the first standard contacts 261 can be arranged at non-equidistant intervals along the direction of the first arc L1. If the distance between two adjacent first standard contacts 261 is large, the width and area of ​​the first extended contact 271 between the two first standard contacts 261 can be set as large as possible. For example, the first extended contact 271 between the two first standard contacts 261 does not need to be provided with any avoidance chamfer 2670, or an avoidance chamfer 2670 is only provided on one side, etc.

[0092] like Figure 10 , Figure 11 and Figure 12 As shown, at least one side of at least one first standard contact 261 is provided with a clearance chamfer 2670 along the direction of the first arc L1. The purpose of this arrangement is to provide space between two adjacent first standard contacts 261 for the insertion of the first extension contact 271 without affecting the function of the first standard contact 261.

[0093] Along the direction of the first arc L1 and the second arc L2, between the adjacent first standard contact 261 and the first extended contact 271, on the side where they are close to each other, either one of them can be provided with a chamfer 2670, or both can be provided with a chamfer 2670.

[0094] The first standard contact group 26 is used to transmit electrical signals, data signals, and control signals between the first chip 28 and the second chip 17. The number and definition of the specific first standard contacts 261 within the first standard contact group 26 may differ.

[0095] In some embodiments of this application, such as Figure 10 , Figure 11 and Figure 12 As shown, in the first extended contact group 27, multiple first extended contacts 271 include a data signal contact (SDA), a ground contact (PGND), a clock signal contact (SCL), and a positive power contact (VDD). The positive power contact (VDD) and the ground contact (PGND) form a group of contacts for transmitting electrical signals. The data signal contact (SDA) and the clock signal contact (SCL) form a group of contacts for transmitting data signals.

[0096] In some embodiments of this application, such as Figure 10 , Figure 11 and Figure 12 As shown, in the first standard contact group 26, multiple first standard contacts 261 include a position detection contact (MIF), a ground contact (PGND), an interface contact (TYPE), and a power positive contact (VBAT). Optionally, the position detection contact (MIF), ground contact (PGND), interface contact (TYPE), and power positive contact (VBAT) are arranged continuously and sequentially in a counterclockwise direction (when the person is facing the rear end of the lens module 200).

[0097] In some embodiments of this application, such as Figure 10 , Figure 11 and Figure 12 As shown, along the direction of the second arc L2: the data signal contact (SDA) in the first extended contact group 27 is close to or in contact with the position detection contact (MIF) in the first standard contact group 26. Specifically, the data signal contact (SDA) in the first extended contact group 27 is located on one side of the position detection contact (MIF) in the first standard contact group 26 in a clockwise direction.

[0098] In some embodiments of this application, such as Figure 10 , Figure 11 and Figure 12 As shown, the grounding contact (PGND) in the first extended contact group 27 is close to or in contact with the grounding contact (PGND) in the first standard contact group 26. Specifically, the grounding contact (PGND) in the first extended contact group 27 is located on the clockwise side of the grounding contact (PGND) in the first standard contact group 26.

[0099] In some embodiments of this application, such as Figure 10 , Figure 11 and Figure 12As shown, the clock signal contact (SCL) in the first extended contact group 27 is close to or in contact with the interface contact (TYPE) in the first standard contact group 26. Specifically, the clock signal contact (SCL) in the first extended contact group 27 is located on one side of the interface contact (TYPE) in the first standard contact group 26 in a clockwise direction.

[0100] In some embodiments of this application, such as Figure 10 , Figure 11 and Figure 12 As shown, the positive power contact (VDD) in the first extended contact group 27 is close to or in contact with the positive power contact (VBAT) in the first standard contact group 26. Specifically, the positive power contact (VDD) in the first extended contact group 27 is located on the clockwise side of the positive power contact (VBAT) in the first standard contact group 26.

[0101] In some embodiments of this application, such as Figure 12 As shown, it is also possible to interchange the positions of the positive power contact (VDD) and the ground contact (PGND) in the first extended contact group 27. Specifically, as... Figure 12 As shown, the positive power contact (VDD) in the first extended contact group 27 is close to or in contact with the ground contact (PGND) in the first standard contact group 26, and the ground contact (PGND) in the first extended contact group 27 is close to or in contact with the positive power contact (VBAT) in the first standard contact group 26.

[0102] In some embodiments, in a counter-clockwise direction, the positive power contact (VDD) in the first extended contact group 27 is in contact with the ground contact (PGND) in the first standard contact group 26, and the ground contact (PGND) in the first extended contact group 27 is in contact with the positive power contact (VBAT) in the first standard contact group 26. In this embodiment, in the lens module 200, a diode bridge rectifier circuit can be used in the first chip 28 to exchange the positive and negative terminals of the power signal after its ground contact (PGND) and positive power contact (VDD) and before the extended function module.

[0103] Next, please refer to Figure 2 , Figure 3 and Figure 4 The following describes a fuselage module 100 according to an embodiment of this application. The fuselage module 100 includes a fuselage body 11 and a second standard contact group 15 disposed on the fuselage body 11. The fuselage body 11 has a front end face facing the fuselage module 100. The second standard contact group 15 includes a plurality of second standard contacts 151, which are disposed on the fuselage body 11 and exposed on its front end face. The second standard contact group 15 is used to mate with a first standard contact group 26. Figure 8 and Figure 9 As shown, when the lens module 200 and the body module 100 are docked in the front-to-back direction, the second standard contact 151 forms physical contact and electrical connection with the first standard contact 261 respectively.

[0104] like Figure 2 , Figure 3 , Figure 4 As shown, the fuselage module 100 also includes a second expansion contact group 16, which includes a plurality of second expansion contacts 161. The second expansion contacts 161 are located on the fuselage body 11 and exposed on the rear end face. The second expansion contact group 16 is used to mate with the first expansion contact group 27. Figure 8 and Figure 9 As shown, when the lens module 200 and the body module 100 are docked in the front-to-back direction, the second extension contact 161 forms physical contact and electrical connection with the first extension contact 271 respectively.

[0105] The lens module 200 and the body module 100 are connected along the front-to-back direction. Therefore, the second standard contact group 15 is mirror-symmetrical to the first standard contact group 26, and the second extended contact group 16 is mirror-symmetrical to the first extended contact group 27. The definitions of each second standard contact 151 are mirror-symmetrical to the definitions of the first standard contact 261. The definitions of each second extended contact 161 are mirror-symmetrical to the definitions of the first extended contact 271. Based on this, the arrangement of the second standard contact group 15 and the second extended contact group 16 will not be described in detail.

[0106] In some embodiments, the area of ​​the second standard contact 151 is smaller than the area of ​​the first standard contact 261, and the area of ​​the second extended contact 161 is smaller than the area of ​​the first extended contact 271. Based on this, the second standard contact 151 and the second extended contact 161 each have a larger space for arrangement. Optionally, as... Figure 2 , Figure 3 and Figure 4 As shown, the second standard contact 151 and the second extended contact 161 are both cylindrical.

[0107] Optionally, the second standard contact 151 and / or the second extended contact 161 are resilient contacts that can extend and retract along the front-rear direction on the body 11. Thus, when the lens module 200 and the body module 100 are aligned in the front-rear direction, the second standard contact 151 can resiliently abut against the first standard contact 261, and the second extended contact 161 can resiliently abut against the first extended contact 271.

[0108] Next, we will introduce the detachable connection method of the lens module 200 and the body module 100 of this application.

[0109] like Figure 2 , Figure 3 , Figure 4 , Figure 16 as well as Figure 7 As shown, the front end face of the fuselage module 100 has a rearwardly recessed limiting hole 130, such as... Figure 5 , Figure 6 , Figure 7 , Figure 16 and Figure 17 As shown, the lens module 200 also includes an operation component 25 disposed on the side of the lens body 22. The operation component 25 includes a limiting pin 251 and a reset member 252. The limiting pin 251 is slidably disposed on the lens body 22 along an axis X parallel to the imaging device 300. The reset member 252 is used to provide a force to move the limiting pin 251 toward the body module 100.

[0110] In the circumferential direction (around the optical axis) of the imaging device 300, with reference to the body module 100, the lens module 200 has a first position and a second position. In the first position, the limiting pin 251 is partially located in the limiting hole 130, and the body module 100 and the lens module 200 are connected and docked along the axial direction X. In the second position, the body module 100 and the lens module 200 can be separated along the axial direction X.

[0111] In other words, when the rear end of the limiting pin 251 is located within the limiting hole 130, the lens module 200 cannot rotate relative to the body module 100. At this time, the body module 100 and the lens module 200 remain connected along the axial direction X, and the imaging device 300 can be used normally. When the rear end of the limiting pin 251 disengages from the limiting hole 130, the lens module 200 can rotate relative to the body module 100 and rotate to the second position. At this time, the lens module 200 and the body module 100 can be separated from each other along the axial direction X.

[0112] In some embodiments of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the fuselage module 100 also includes a second bayonet assembly 13 located at the front end of the fuselage body 11, such as... Figure 2 , Figure 3 and Figure 4 As shown, the lens module 200 also includes a first bayonet assembly 24 located at the rear end of the lens body 22. The first bayonet assembly 24 and the second bayonet assembly 13 can be connected and separated along the X-axis. Specifically, in a first position, the first bayonet assembly 24 and the second bayonet assembly 13 are connected along the X-axis, and in a second position, the first bayonet assembly 24 and the second bayonet assembly 13 can be separated along the X-axis.

[0113] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 4As shown, the limiting hole 130 is provided on the second bayonet assembly 13. Optionally, as... Figures 5 to 7 As shown, the limiting pin 251 is disposed on the periphery of the first bayonet assembly 24 along a direction parallel to the optical axis of the imaging device 300, that is, the limiting pin 251 does not need to pass through the first bayonet assembly 24. This is beneficial to the manufacturing and assembly of the first bayonet assembly 24.

[0114] In some embodiments of this application, such as Figure 4 , Figure 13 , Figure 14 and Figure 15 As shown, the second bayonet assembly 13 includes a second bayonet member 131, which has a second light-transmitting hole 1313 extending through the axial direction X. The inner side of the second bayonet member 131 is provided with a plurality of second limiting portions 1312 spaced circumferentially and protruding radially along the fuselage module 100; Figure 7 , Figure 13 , Figure 14 and Figure 15 As shown, the first bayonet assembly 24 includes a first bayonet member 242, which has a first light-transmitting hole 2423 extending along the axial direction X. The first bayonet member 242 has at least one first limiting portion 2422 protruding radially outward along the body module 100. The circumferential width of the first limiting portion 2422 is less than or equal to the circumferential width of the gap between adjacent second limiting portions 1312. In a first position, the first limiting portion 2422 is at least partially located on the side of the second limiting portion 1312 facing away from the lens module 200, i.e., the rear side. In a second position, the first limiting portion 2422 can be located between two adjacent second limiting portions 1312, and thus can move forward along the axial direction X to disengage from the body module 100.

[0115] Specifically, in some embodiments of this application, such as Figure 13 , Figure 14 and Figure 15 As shown, the second bayonet component 131 includes a ring-shaped second bayonet body 1311 with the aforementioned second light-transmitting hole 1313, and a second limiting portion 1312 is disposed on the inner circumferential side of the second bayonet body 1311 and protrudes outward. The second bayonet body 1311 is used for fixed connection with the fuselage body 11; for example, the second bayonet body 1311 is fixedly disposed at the front end of the fuselage body 11 by fasteners such as bolts.

[0116] like Figure 7 , Figure 13 , Figure 14 and Figure 15As shown, in some embodiments of this application, the first bayonet mount 242 includes a first bayonet body 2421 that is annular and has the aforementioned first light-transmitting hole 2423. A first limiting portion 2422 is disposed on the side of the second bayonet body 1311 along the axial direction X, close to the body module 100, and spaced a certain distance from the second bayonet body 1311. The first bayonet body 2421 is used for fixed connection with the lens body 22. For example, the first bayonet body 2421 is fixedly disposed on the rear end of the lens body 22 by fasteners such as bolts.

[0117] In some embodiments of this application, such as Figure 7 , Figure 13 , Figure 14 and Figure 15 As shown, the second bayonet assembly 13 also includes an elastic element 133, which is fixedly disposed on the body 11 and located on the rear side of the second bayonet 131. In the first position, the elastic element 133 is compressed on one side of the first limiting portion 2422 along the axial direction X. For example, the elastic element 133 can be compressed on the rear side of the first limiting portion 2422, which causes the first limiting portion 2422 of the lens module 200 to abut against the second limiting portion 1312 in the forward direction to maintain relative fixation. Alternatively, the elastic element 133 can be compressed on the front side of the first limiting portion 2422 and the rear side of the second limiting portion 1312, which causes the lens module 200 to abut against the body 11 in the rearward direction to maintain relative fixation.

[0118] In some embodiments of this application, such as Figure 15 As shown, in the first position, the elastic member 133 is compressed between the first limiting part 2422 and the second locking member 131.

[0119] In some embodiments of this application, such as Figure 13 , Figure 14 and Figure 15 As shown, the elastic element 133 includes an elastic element body 1331 and at least one elastic part 1332. The elastic element body 1331 is fixedly connected to the rear side of the second bayonet 131 so that the elastic element body 1331 is also fixed on the fuselage body 11.

[0120] Optionally, such as Figure 14 As shown, there are multiple first limiting parts 2422, second limiting parts 1312, and elastic parts 1332 in the circumferential direction of the body module 100. The purpose of this arrangement is that the first bayonet assembly 24 and the second bayonet assembly 13 are connected at multiple points, which helps to keep the lens module 200 stably on the body module 100 as a whole.

[0121] In some embodiments of this application, such as Figure 13 , Figure 14As shown, in the circumferential direction of the fuselage module 100, the second limiting portion 1312 includes two spaced-apart limiting protrusions 13120, and the elastic portion 1332 is located between the two limiting protrusions 13120 in adjacent second limiting portions 1312. The purpose of this arrangement is that when the first limiting portion 2422 enters between two adjacent second limiting portions 1312 along the axial direction X, the elastic portion 1332 will not interfere with the movement of the first limiting portion 2422, and when the first limiting portion 2422 reaches the first position, it can just compress the elastic portion 1332.

[0122] The form of the elastic part 1332 is not limited, as long as it can undergo elastic deformation when subjected to an axial X-force. For example, see Figure 14 As shown, the elastic part 1332 is a spring sheet, one end of which is fixed to the elastic body 1331, and the other end protrudes radially and axially (X) relative to the elastic body 1331 in the fuselage module 100. In other alternative embodiments, the elastic part 1332 may take the form of a spring, an elastic protrusion, etc., which are not particularly limited here.

[0123] Depending on the thickness of the second bayonet body 1311 and the thickness of the elastic element body 1331, the limiting hole 130 can be provided through the second bayonet body 1311, such as... Figure 4 As shown, it can be configured without penetrating the second bayonet body 1311, or it can be configured to penetrate both the second bayonet body 1311 and the elastic element body 1331.

[0124] In some embodiments of this application, such as Figure 7 , Figure 15 , Figure 16 and Figure 17 As shown, the first bayonet assembly 24 also includes a sealing member 244, which is disposed between the periphery of the first bayonet member 242 and the inner peripheral wall of the lens body 22. The sealing member 244 is used to seal the gap around the first bayonet member 242, thereby forming a closed space inside the lens body 22.

[0125] like Figure 5 , Figure 6 and Figure 7 As shown, a first contact mounting portion 245 is provided on the inner periphery of the first limiting portion 2422, and both the first standard contact 261 and the first extended contact 271 are provided on the first contact mounting portion 245. Figure 2 , Figure 3 and Figure 4 As shown, the main body 11 is provided with a second contact mounting part 111, and the second standard contact 151 and the second extended contact 161 are both provided on the second contact mounting part 111.

[0126] In some embodiments of this application, such as Figure 6 , Figure 16 and Figure 17 As shown, the lens body 22 has a receiving cavity 220 and a sliding hole 221 that are interconnected. The reset member 252 is located within the receiving cavity 220, and a portion of the limiting pin 251 is located within the receiving cavity 220. The sliding hole 221 penetrates the lens body 22 radially along the body module 100; as shown... Figure 16 and Figure 17 As shown, the operation component 25 also includes an operation member 253. A part of the operation member 253 is connected to the limiting pin 251 via the sliding hole 221, and the other part of the operation member 253 is located outside the lens body 22. The operation member 253 is used to drive the limiting pin 251 to move away from the body module 100.

[0127] Therefore, outside the lens body 22, the operator can operate the operating member 253 to make the limiting pin 251 overcome the rearward force provided by the reset member 252, thereby causing the limiting pin 251 to move forward and disengage from the limiting hole 130 of the body module 100.

[0128] There are several ways in which the operating component 253 can drive the limit pin 251 to move forward.

[0129] Please see Figure 16 As shown, in some embodiments of this application, the sliding hole 221 is arranged along the axial direction X, that is, the sliding hole 221 is an elongated hole arranged along the axial direction X, and the operating member 253 can slide along the axial direction X. The operating member 253 is fixedly connected to the limiting pin 251. The operator moves the operating member 253 forward by flicking it with his finger, thereby moving the limiting pin 251 forward.

[0130] The reset element 252 may be a spring sleeved on the limit pin 251. In other embodiments, the reset element 252 may be other types of elastic bodies disposed at the front end of the limit pin 251.

[0131] Alternatively, please see Figure 17As shown, in some embodiments of this application, the operating member 253 is capable of moving radially within the sliding hole 221 along the body module 100. One end of the operating member 253 located within the receiving cavity 220 is provided with a slope 2530, which is used to slide against the end of the positioning pin facing away from the body module 100. The slope 2530 is a surface that gradually slopes forward in a radially outward direction along the body module 100. The reset member 252 includes a first reset member 2521 and a second reset member 2522. The first reset member 2521 is connected to the operating member 253 and provides a force for the operating member 253 to move radially outward along the body module 100. The second reset member 2522 is connected to the limiting pin 251 and provides a force for the limiting pin 251 to move axially forward. Therefore, when the operator does not apply force to the operating member 253, under the action of the first reset member 2521 and the second reset member 2522, the operating member 253 protrudes more radially along the body module 100, and the limiting pin 251 is more rearward along the axial direction X. When the operating member 253 is pressed inward, the operating member 253 moves inward radially along the body module 100, and the limiting pin 251 moves forward.

[0132] In many other embodiments, the operating component 25 may also take other forms, such as a knob assembly. Any method that allows the limit pin 251 to move in the axial direction X can be applied.

[0133] In this application, the position of the limiting hole 130 on the body module 100 is not limited. Optionally, as... Figure 2 As shown, the limiting hole 130 is located on one side of the body module 100 in the width direction. Further optionally, the limiting hole 130 is aligned with the optical axis in the width direction. In other optional embodiments, the limiting hole 130 may also be located in other positions of the body module 100, such as the lower right side, upper right side, or upper side. Examples will not be elaborated further.

[0134] Please see Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of this application, the front end of the fuselage module 100 is provided with a second positioning part 134, such as... Figure 6 and Figure 7As shown, a first positioning part 240 is provided on the front end or outer peripheral surface of the lens module 200. The first positioning part 240 and the second positioning part 134 are used to indicate the position of the lens module 200 relative to the body module 100, for example, to indicate a second position. For example, in the process of installing the lens module 200 onto the body module 100, in the second position, the first limiting part 2422 should be aligned with the adjacent second limiting part 1312. Since the positions of the first limiting part 2422 and the second limiting part 1312 are relatively inward, the operator cannot fully and simultaneously observe the positions of the first limiting part 2422 and the second limiting part 1312. Therefore, the first positioning part 240 and the second positioning part 134 can be used to assist the operator's observation. For example, when viewed from front to back, when the first positioning part 240 and the second positioning part 134 are aligned, it means that the first limiting part 2422 is aligned between two adjacent second limiting parts 1312. At this time, the entire lens module 200 can be pushed backward and then rotated to make the lens module 200 reach the first position.

[0135] The form of the first positioning part 240 and the second positioning part 134 is not limited. For example, either the first positioning part 240 or the second positioning part 134 can be an indicator mark that combines one or more of the following forms: raised area, recessed area, text, color block, pattern, etc. For example, the first positioning part 240 and the second positioning part 134 are each set as a red bar area.

[0136] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the second positioning part 134 is disposed on the upper part of the second bayonet assembly 13 and located on the upper side of the optical axis of the body 11. In the vertical direction, the second positioning part 134 is located on the upper side and in the center of the second bayonet assembly 13. This is more in line with the operator's orientation habits when assembling and disassembling the lens module 200. Specifically, as Figure 4 As shown, the first positioning part 240 can be located at the upper middle position of the second bayonet body 1311.

[0137] Correspondingly, the position of the first positioning part 240 on the lens module 200 can be set according to the angle between the first position and the second position. For example, if the lens module 200 can reach the first position after rotating 45° clockwise from the second position, then the first positioning part 240 can be positioned at the upper right of the lens module 200. If the lens module 200 can reach the first position after rotating 90° clockwise from the second position, then the first positioning part 240 can be positioned at the right side of the lens module 200.

[0138] In some embodiments, such as Figure 6 and Figure 7As shown, the first positioning part 240 is disposed on the outer peripheral surface of the lens body 22 and located at the rear end of the lens body 22. That is, the first positioning part 240 is disposed as far back as possible on the outer peripheral surface of the lens body 22. This further facilitates the operator to directly observe the first positioning part 240 and whether the first positioning part 240 is aligned with the second positioning part 134 when installing the lens module 200. In other optional embodiments, the first positioning part 240 and the second positioning part 134 can also be arranged in other ways, as long as the operator can quickly determine the orientation of the lens module 200 when installing the lens module 200.

[0139] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
