Description

[0001] Cross-referencing of related applications:

[0002] This application is based on and claims priority to PCT international patent application No. PCT / CN2025 / 074903, filed on January 24, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of photography technology, and more particularly to cameras. Background Technology

[0004] To meet the needs of shooting in various scenarios or for lens storage, camera bodies and lenses are typically designed to be detachable. In these technologies, a camera mount is designed on the camera body. When mounting a lens to the camera body, alignment marks on both the lens mount and the camera mount must be found to align them before inserting the lens into the body. Because the markings must be visually located, blind operation is not possible, resulting in low installation efficiency.

[0005] Application content

[0006] In view of this, this application proposes a camera.

[0007] The camera according to the first aspect of this application includes: a camera body with a lens interface; a lens assembly configured to be detachably mounted to the lens interface; a mating structure disposed on the lens assembly; and a first locking structure disposed on the camera body and configured to move with the relative rotation of the camera body and the lens assembly to be in a first state or a second state; wherein, in the first state, the first locking structure engages with the mating structure to lock the movement of the lens assembly relative to the camera body along the optical axis of the lens assembly, and in the second state, the first locking structure disengages from the mating structure to unlock the movement of the lens assembly relative to the camera body along the optical axis, and in the first state and the second state, at least a portion of the first locking structure is positioned differently along a direction perpendicular to the optical axis of the lens assembly.

[0008] By adopting the solution of the first aspect of this application, the first locking structure can move with the relative rotation of the camera body and the lens assembly and be in a first state and a second state. In the first state and the second state, the position of the first locking mechanism is different along the optical axis direction perpendicular to the lens assembly, so as to lock or unlock the movement of the lens assembly relative to the camera body along the optical axis direction. In this way, the first locking structure can be unlocked or locked by moving along the optical axis direction during the rotation. This makes it easier for the lens assembly to be detached from and installed from the camera body due to the movement of the first locking structure in the unlocked state, thereby improving the convenience of disassembly and installation of the lens assembly.

[0009] The camera according to the second aspect of this application includes: a camera body with a lens interface; a lens assembly configured to be detachably mounted on the lens interface; multiple conductive strips disposed on one of the camera body and the lens assembly; and multiple electrical contacts disposed on the other of the camera body and the lens assembly, and corresponding one-to-one with the multiple conductive strips to electrically connect the camera body and the lens assembly; wherein the conductive strips are annular, and the multiple conductive strips and the multiple electrical contacts are disposed one-to-one along the optical axis of the lens assembly.

[0010] By adopting the solution of the second aspect of this application, when the lens assembly is installed on the lens interface, since multiple conductive strips extend circumferentially and form a closed shape, the electrical contacts can make alignment contact with the corresponding conductive strips regardless of the angle from which the lens assembly is installed on the lens interface. This achieves electrical connection between the camera body and the lens assembly after installation, which is beneficial for real-time data transmission between the lens assembly and the camera body after installation. The lens assembly itself has a relatively long distance along the optical axis, and the arrangement of multiple conductive strips and multiple electrical contacts along the optical axis reduces the space occupied by the camera body or lens assembly in the direction perpendicular to the optical axis, effectively improving space utilization and achieving reliable electrical connection. This effectively prevents poor contact caused by single point contact and improves the speed, reliability, and accuracy of data transmission.

[0074] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0075] Existing camera or lens assembly installation methods require aligning the lens assembly with a unique alignment mark on the camera mount. Furthermore, the three-lobed jaws of the mount are designed with a non-centrally symmetrical shape to ensure the lens assembly can only be inserted into the camera mount at a single, fixed angle. This necessitates the lens assembly being inserted into the camera body at a specific angle for locking and electrical connection. After rotating to the fixed angle, the spring connector and contacts can properly engage and conduct electricity. This locking and electrical connection structure relies heavily on visual inspection and manual operation during alignment, making it extremely inconvenient and impossible to perform blind operation.

[0076] In view of this, this application proposes a camera 100 aimed at solving at least one of the aforementioned technical problems.

[0077] Please see Figure 1 , Figure 2 , Figure 3 and Figure 24 A camera 100 according to an embodiment of this application includes: a camera body 10 (see...) Figure 3 , Figure 6 , Figure 23 and Figure 24 ), lens assembly 20, mating structure 30 and first locking structure 40.

[0078] Among them, such as Figure 6 As shown, the body 10 is provided with a lens interface 11, which can be used to insert the lens assembly 20.

[0079] The lens assembly 20 is configured to be detachably mounted on the lens interface 11.

[0080] The cooperating structure 30 is disposed on the lens assembly 20, and the first locking structure 40 is disposed on the camera body 10. The first locking structure 40 is configured to move with the relative rotation of the camera body 10 and the lens assembly 20 to be in a first state or a second state. That is, when there is relative rotation between the lens assembly 20 and the camera body 10, the first locking structure 40 can switch its own state or position.

[0081] Furthermore, in the first state, the first locking structure 40 engages with the cooperating structure 30 to lock the movement of the lens assembly 20 relative to the body 10 along the optical axis of the lens assembly 20. In the second state, the first locking structure 40 disengages from the cooperating structure 30 to unlock the movement of the lens assembly 20 relative to the body 10 along the optical axis. In the first state and the second state, at least a portion of the first locking structure 40 is positioned differently along the direction perpendicular to the optical axis of the lens assembly 20.

[0082] As can be seen from the above, with the solution of the camera 100 of this application, the first locking structure 40 can move in a first state and a second state as the camera body 10 and lens assembly 20 rotate relative to each other. The first locking structure 40 is positioned differently in the first state and the second state along the optical axis perpendicular to the lens assembly 20, thereby locking or unlocking the movement of the lens assembly 20 relative to the camera body 10 along the optical axis. Thus, the movement of the first locking structure 40 along the optical axis during rotation can unlock or lock the lens assembly 20 relative to the camera body 10. This makes it easier for the lens assembly 20 to detach from and install on the camera body 10 in the unlocked state due to the movement of the first locking structure 40, improving the convenience of disassembling and installing the lens assembly 20.

[0083] Specifically, during installation, the lens assembly 20 first moves along the optical axis to be installed in the lens interface 11 of the camera body 10. Then, the relative rotation between the lens assembly 20 and the camera body 10 locks the movement of the lens assembly 20 and the camera body 10 along the optical axis. During the rotational installation of the lens assembly 20 relative to the camera body 10 in the first rotation direction, the first locking structure 40 changes its position perpendicular to the optical axis and enters a first state, thereby locking with the mating structure 30. This locks the lens assembly 20 relative to the camera body 10 in the optical axis direction, preventing the lens assembly 20 from detaching from the camera body 10. Simultaneously, the first locking structure 40 is in a blocking position that prevents the lens assembly 20 from moving along the optical axis. If it is closer to the optical axis, the first locking structure 40 and the mating structure 30 achieve a tight locking engagement along the optical axis. The first rotation direction can be clockwise or counterclockwise.

[0084] During disassembly, the lens assembly 20 can rotate relative to the camera body 10 in a second rotation direction. The first locking structure 40 changes its position perpendicular to the optical axis and enters a second state, thereby disengaging from the mating structure 30. This unlocks the lens assembly 20 relative to the camera body 10 in the optical axis direction, allowing the lens assembly 20 to be removed from the camera body 10. Simultaneously, the first locking structure 40 is positioned to avoid movement of the lens assembly 20 along the optical axis, such as a position further away from the optical axis, facilitating the removal of the lens assembly 20 from the camera body 10 and making it easier to install the lens assembly 20 next time. The second rotation direction can be opposite to the first rotation direction.

[0085] Therefore, it is understandable that the entire disassembly and assembly process of the camera 100 of this application is simple, has few steps, and saves time and effort. Compared with the lens and camera mount in the prior art that requires alignment and installation at a unique angle, the camera 100 of this application can change the locked or unlocked state by moving the first locking structure 40, thereby reducing the obstruction of the first locking structure 40 to the mating structure 30 during the installation process; compared with the prior art that requires the snap-fit ​​structure to be adjusted to a clearance state before installing the lens, the camera 100 of this application can adjust the position and state of the first locking structure 40 when the lens assembly 20 and the body 10 rotate relative to each other, realizing the locking and unlocking of the first locking structure 40 and the mating structure 30, and in the unlocked state, it is in a clearance position, which facilitates the disassembly and assembly of the lens assembly 20 relative to the body 10. The disassembly and assembly steps are simple and convenient to operate.

[0086] The camera 100 of this application can also quickly change different lens components 20 as needed, thereby enabling users to capture fleeting shooting opportunities and improve the user's shooting experience.

[0087] The specific cooperation form of the cooperation structure 30 and the first locking structure 40 of this application will be described in detail below.

[0088] In some embodiments of this application, combined with Figure 6 , Figure 7 and Figure 8 As shown, in the first and second states, the first locking structure 40 pairs with the lens interface 11 (as shown). Figure 6 The degree of occlusion varies (as shown), that is, as... Figure 8 As shown, when the first locking structure 40 obstructs the lens interface 11 to a large extent, the lens assembly 20 relative to the body 10 (e.g., Figure 3 , Figure 6 and Figure 23 (As shown) The lens assembly 20 cannot move arbitrarily or it is inconvenient to move in the optical axis direction. At this time, the first locking structure 40 and the mating structure 30 can form a lock, and the lens assembly 20 is locked to the body 10 and cannot be dislodged; as shown Figure 7 As shown, when the first locking structure 40 slightly obstructs the lens interface 11, the lens assembly 20 can be easily moved relative to the camera body 10 along the optical axis direction. This facilitates the removal of the lens assembly 20 from the camera body 10 along the optical axis direction, or the installation of the lens assembly 20 onto the camera body 10 along the optical axis direction. Therefore, the first locking structure 40 of this application can lock and unlock the movement of the lens assembly 20 relative to the camera body 10 along the optical axis direction.

[0089] It is understood that the lens interface 11 can be a cylindrical interface, and the lens interface 11 can form an approximately cylindrical receiving cavity to accommodate the lens assembly 20. The different degrees of obstruction of the lens interface 11 by the first locking structure 40 can refer to the movement of the first locking structure 40 in a direction perpendicular to the optical axis, so as to change the shape and / or volume of the receiving cavity.

[0090] In some embodiments of this application, the effective inner diameter of the lens interface 11 differs between the first and second states. Here, the effective inner diameter can be understood as the inner diameter through which other components, such as the lens assembly 20, can pass. For example, it could be the minimum inner diameter of the aforementioned cylindrical receiving cavity. Therefore, in the first state, the movement of the first locking structure 40 reduces the effective inner diameter of the lens interface 11, allowing the first locking structure 40 to lock onto the mating structure 30, thus enabling the lens assembly 20 to engage with the lens interface 11. In the second state, the movement of the first locking structure 40 increases the effective inner diameter of the lens interface 11, allowing the lens assembly 20 to either disengage from the lens interface 11 along the optical axis or be mounted on the lens interface 11 along the optical axis.

[0091] In some embodiments of this application, such as Figure 3 , Figure 4 and Figure 6 As shown, the first locking structure 40 includes a transmission member 42 and a first locking member 41. The transmission member 42 is connected to the first locking member 41, and the transmission member 42 is configured to follow the fuselage 10 (e.g., Figure 3 , Figure 6 and Figure 23 The transmission member 42 rotates relative to the lens assembly 20, and the rotation of the transmission member 42 drives the first locking member 41 to move, thereby changing the position of the first locking member 41 at least in the direction perpendicular to the optical axis. That is to say, the transmission member 42 can be designed to rotate when the body 10 rotates, or the transmission member 42 can be set to rotate when the lens assembly 20 rotates, and the first locking member 41 further moves with the rotation of the transmission member 42.

[0092] In some embodiments of this application, such as Figure 3 and Figure 5 As shown, the mating structure 30 includes a first mating part 31, which is configured to mate with the transmission member 42. When the first mating part 31 mates with the transmission member 42, the first mating part 31 and the transmission member 42 rotate synchronously. Therefore, during the assembly and disassembly of the lens assembly 20 relative to the camera body 10, as long as the lens assembly 20 is not disengaged from the camera body 10, the mating first mating part 31 and the transmission member 42 can rotate synchronously. That is, if one of the first mating part 31 and the transmission member 42 rotates, the other will rotate synchronously. This allows the lens assembly 20 to rotate smoothly and stably relative to the camera body 10 until the lens assembly 20 has rotated to its final position, at which point the first mating part 31 and the transmission member 42 stop rotating, or until the lens assembly 20 has rotated to the point of disengagement from the camera body 10, at which point the first mating part 31 and the transmission member 42 also stop engaging and cease synchronous rotation.

[0093] In some embodiments of this application, such as Figure 3 and Figure 5As shown, the mating structure 30 includes a second mating part 32, which is configured to engage with the first locking member 41 when the first locking structure 40 is in a first state, and to disengage from the first locking member 41 when the first locking structure 40 is in a second state. Since the first locking member 41 is connected to the transmission member 42, when the transmission member 42 and the first mating part 31 rotate synchronously, the first locking member 41 will also rotate with the transmission member 42 and switch states and positions. Therefore, when the lens assembly 20 rotates to engage with the body 10, the first locking structure 40 is in the first state, and the first locking member 41 rotates to engage with the second mating part 32. After the first locking member 41 and the second mating part 32 engage, the movement of the lens assembly 20 relative to the body 10 in the optical axis direction can be locked. When the lens assembly 20 is rotated to the direction of disengagement from the body 10, the first locking structure 40 switches from the first state to the second state. Then, the first locking member 41 rotates to disengage from the second mating part 32, thereby unlocking the movement of the lens assembly 20 relative to the body 10 in the optical axis direction. This allows the lens assembly 20 to be disassembled relative to the body 10, and also facilitates the next further installation of the lens assembly 20 onto the body 10.

[0094] In a further embodiment, such as Figure 3 and Figure 5 As shown, the first mating part 31 includes a first retaining tooth 311, as... Figure 2 and Figure 4 As shown, the transmission component 42 includes a second locking tooth 421. When the first locking tooth 311 and the second locking tooth 421 are engaged, the first mating part 31 rotates synchronously with the transmission component 42. In these embodiments, the first locking tooth 311 and the second locking tooth 421 can achieve rapid alignment and meshing, and the meshing connection area is large, thereby forming a stable connection. After the first locking tooth 311 and the second locking tooth 421 are connected in place, they do not move relative to each other in the optical axis direction, nor do they rotate relative to each other in the circumferential direction. However, when subjected to an externally applied rotational force, they can rotate synchronously, and while rotating, they always maintain a relatively stable contact.

[0095] In some embodiments, such as Figure 5As shown, there are multiple first locking teeth 311, and these multiple first locking teeth 311 are arranged circumferentially along the mating structure 30. Therefore, the multiple first locking teeth 311 can be aligned with a full circle of second locking teeth 421, allowing the multiple first locking teeth 311 to engage and latch with the second locking teeth 421 at any position circumferentially. The multiple first locking teeth 311 can also latch with the multiple second locking teeth 421, and the arc-shaped gap between adjacent second locking teeth 421 is smaller than the length of the first locking teeth 311, or the arc-shaped gap between adjacent first locking teeth 311 is smaller than the length of the second locking teeth 421. This ensures that the multiple first locking teeth 311 and multiple second locking teeth 421 can latch regardless of their relative circumferential position, ultimately enabling the lens assembly 20 to be mounted relative to the camera body 10 at any angle.

[0096] In some embodiments, there are multiple second locking teeth 421, and these multiple second locking teeth 421 are arranged circumferentially along the first locking structure 40. Similar to the arrangement of the first locking teeth 311, the second locking teeth 421 can also be aligned with a full circle of first locking teeth 311, allowing the multiple second locking teeth 421 to engage and latch with the first locking teeth 311 at any circumferential position. The multiple second locking teeth 421 can also latch with the multiple first locking teeth 311, with the arcuate gap between adjacent first locking teeth 311 being smaller than the length of the second locking teeth 421, or vice versa. This ensures that the multiple first locking teeth 311 and multiple second locking teeth 421 can latch regardless of their relative circumferential position, ultimately enabling the lens assembly 20 to be installed relative to the body 10 at any angle.

[0097] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the transmission component 42 includes a positioning part 422, which engages with the first mating part 31, so that the mating structure 30 drives the transmission component 42 to rotate through the first mating part 31 and the positioning part 422. The positioning part 422 may include the aforementioned second locking tooth 421, and the first mating part 31 may also include the aforementioned first locking tooth 311; the positioning part 422 and the first mating part 31 may also be a combination of a positioning pin and a positioning groove, which is not specifically limited here.

[0098] In some embodiments, there are multiple first mating parts 31, which are arranged circumferentially along the lens assembly 20. The positioning part 422 can selectively engage with at least one of the first mating parts 31. That is, during the installation of the lens assembly 20 onto the body 10, regardless of the installation angle, the positioning part 422 can engage with at least one first mating part 31, thereby enabling the transmission member 42 to achieve a positioning connection with the first mating part 31. When the lens assembly 20 rotates relative to the body 10, the mating structure 30 with the first mating part 31 and the transmission member 42 with the positioning part 422 rotate synchronously. While the transmission member 42 rotates, the first locking member 41 can rotate accordingly, thereby enabling the first locking member 41 to lock or unlock the second mating part 32.

[0099] In some embodiments, a plurality of first mating parts 31 are arranged in a circle along the circumference of the lens assembly 20. For example, they can be a plurality of first mating parts 31 arranged at intervals, or a plurality of first mating parts 31 arranged alternately and continuously. In this case, when the lens assembly 20 is assembled on the body 10 at any angle, the positioning part 422 can be positioned and connected with one or more positions of the circled first mating parts 31.

[0100] When multiple first mating parts 31 are arranged at intervals, they can be arranged at equal intervals, which is beneficial to the stability of the center of gravity of the mating structure 30, the structural symmetry, and the rotational stability, and also facilitates the positioning connection between the positioning part 422 and the first mating parts 31. In order to ensure that the positioning part 422 does not fall completely in the gap between two adjacent first mating parts 31, the length of the positioning part 422 in this application is greater than the gap between two adjacent first mating parts 31, so that the positioning part 422 can achieve a positioning connection with at least a portion of the first mating parts 31.

[0101] Similarly, the positioning part 422 of this application can be designed as multiple parts, and the multiple positioning parts 422 are arranged circumferentially along the lens assembly 20. The first mating part 31 can selectively mate with at least one of the positioning parts 422. That is to say, during the process of installing the lens assembly 20 to the body 10, regardless of the installation angle, the first mating part 31 can mate with at least one positioning part 422, thereby enabling the transmission member 42 to achieve a positioning connection with the first mating part 31. When the lens assembly 20 rotates relative to the body 10, the mating structure 30 with the first mating part 31 and the transmission member 42 with the positioning part 422 rotate synchronously. While the transmission member 42 rotates, the first locking member 41 can rotate accordingly, thereby enabling the first locking member 41 to lock or unlock the second mating part 32.

[0102] In some embodiments, a plurality of positioning portions 422 are arranged in a circle around the circumference of the lens assembly 20. For example, they can be a plurality of positioning portions 422 arranged at intervals or a plurality of positioning portions 422 arranged alternately and continuously. In this case, when the lens assembly 20 is assembled on the body 10 at any angle, the first mating portion 31 can be positioned and connected with one or more positions of the circularly arranged positioning portions 422. In this way, it is possible to unlock and lock the lens assembly 20 by the relative rotation between the lens assembly 20 and the body 10 when the lens assembly 20 is installed on the body 10 at any relative rotation angle, so that the user can more conveniently install and remove the lens assembly 20.

[0103] When multiple positioning parts 422 are arranged at intervals, they can be arranged at equal intervals, which is beneficial to the stability of the center of gravity of the transmission component 42, the structural symmetry, and the greater stability of rotation, and also facilitates the positioning connection between the first mating part 31 and the positioning part 422. In order to ensure that the first mating part 31 does not fall completely in the gap between two adjacent positioning parts 422, the length of the first mating part 31 in this application is greater than the gap between two adjacent positioning parts 422, so that the first mating part 31 can achieve a positioning connection with at least a portion of the positioning parts 422.

[0104] In some embodiments of this application, such as Figure 3 and Figure 5 As shown, the second mating part 32 includes a slot 321, such as Figure 3 and Figure 4 As shown, the first locking member 41 includes a claw 411. The claw 411 engages with the slot 321 in the first locking structure 40 in a first state, and disengages from the slot 321 in the first locking structure 40 in a second state. Through the engagement of the claw 411 with the slot 321, the claw 411 can enter the slot 321 in a direction perpendicular to the optical axis, that is, the claw 411 extends towards the optical axis relative to the slot 321, thereby achieving engagement between the claw 411 and the slot 321. Simultaneously, the lens assembly 20 is locked relative to the body 10 in a movement along the optical axis. Alternatively, the claw 411 can leave the slot 321 in a direction perpendicular to the optical axis, that is, the claw 411 retracts away from the slot 321 relative to the slot 321, thereby achieving disengagement between the claw 411 and the slot 321. Simultaneously, the lens assembly 20 is unlocked relative to the body 10 in a movement along the optical axis.

[0105] In some embodiments, such as Figure 3 and Figure 5 As shown, the slot 321 is arranged along the circumference of the lens assembly 20, so that the claw 411 can extend into the slot 321 at any angle along the circumference of the slot 321 to cooperate with the slot 321, and limit the movement of the lens assembly 20 and the body 10 along the optical axis.

[0106] In some embodiments, such as Figure 3 and Figure 4 As shown, there are multiple latches 411, arranged circumferentially along the first locking structure 40. In the first state, the multiple latches 411 engage with different positions along the circumferential direction of the slot 321. The number of latches 411 can be two, three, four, or more; no specific limitation is imposed, and it can be adjusted according to the actual arrangement space and the structural dimensions of the latches 411. When the multiple latches 411 engage with the slot 321 from different positions along the circumference, the uniformity of the engagement force between the first locking member 41 and the second mating part 32 can be improved, and the stability of the movement limitation between the lens assembly 20 and the body 10 in the optical axis direction can be enhanced. In some specific embodiments, such as... Figure 4 , Figure 7 and Figure 8 As shown, there are three claws 411. The three claws 411 have the same shape and size, and are evenly spaced in the circumferential direction. This helps to improve the stress stability of the first locking member 41 and the engagement stability between the first locking member 41 and the second mating part 32.

[0107] The specific structure of the installation component 50 will be described below.

[0108] In some embodiments of this application, such as Figure 3 , Figure 12 , Figure 13 and Figure 24 As shown, the camera 100 also includes a mounting assembly 50 for mounting the first locking structure 40. Therefore, as... Figures 26 to 30 As shown, the mounting component 50 provides the necessary structural foundation for the installation of the first locking structure 40, making the structural design of the first locking structure 40 itself more flexible.

[0109] Optionally, in lens assembly 20 (such as...) Figure 1 , Figure 2 and Figure 3 (as shown) and fuselage 10 (as shown) Figure 3 , Figure 6 and Figure 23 During the relative rotation (as shown), the movement of the first locking member 41 in the direction perpendicular to the optical axis can be guided by the guide structure. The guide structure can be provided in the mounting assembly 50.

[0110] In some embodiments, such as Figure 3 and Figure 4 As shown, the mounting assembly 50 includes a mounting base 51, and the first locking structure 40 includes a first locking member 41. The first locking member 41 cooperates with the mounting base 51, such that the first locking member 41 follows the fuselage 10 (e.g., Figure 3 , Figure 6 and Figure 23As shown, when one of the lens assembly 20 rotates, it can move relative to the mounting base 51 in a preset direction, thereby changing the position of the first locking member 41 at least in the direction perpendicular to the optical axis. Therefore, in these embodiments, when the body 10 and the lens assembly 20 rotate relative to each other, the mounting base 51 provides a certain motion guide for the first locking member 41, causing the position of the first locking member 41 in the direction perpendicular to the optical axis to change, thereby enabling the first locking member 41 to engage or disengage relative to the second mating part 32.

[0111] In some embodiments, the mounting base 51 may be disposed on the housing 10 (e.g., Figure 3 , Figure 6 and Figure 23 As shown), and fixedly connected to the body 10, so that during the relative rotation of the lens assembly 20 and the body 10, the first locking member 41 will move relative to the mounting base 51, and the movement direction of the first locking member 41 can be preset by the guide structure on the mounting base 51.

[0112] In some embodiments, such as Figure 3 and Figure 4 As shown, the mounting base 51 is provided with a first guide portion 511, and the first locking member 41 is provided with a second guide portion 412. The second guide portion 412 cooperates with the first guide portion 511, allowing the first locking member 41 to move relative to the mounting base 51 in a preset direction. When the first locking member 41 rotates with the transmission member 42, the second guide portion 412, under the action of the first guide portion 511, moves the first locking member 41 in the preset direction along the extension direction of the first guide portion 511 and the designed trajectory. This makes the movement path of the first locking member 41 controllable and allows the first locking member 41 and the second mating portion 32 to quickly engage and disengage, thereby improving the working efficiency of the first locking member 41.

[0113] In some embodiments, such as Figure 8 As shown, the first guide portion 511 includes a first guide groove 5111, as... Figure 3 As shown, the second guide portion 412 includes a guide pin 4121, as... Figure 3 and Figure 4 As shown, the first locking member 41 also includes a pawl 411, and a guide pin 4121 is configured to engage with the first guide groove 5111 and move along the first guide groove 5111 when the first locking member 41 rotates, thereby driving the pawl 411 to move. The first guide groove 5111 has a certain extension direction and groove depth. The extension direction of the first guide groove 5111 is set to a preset direction, so that the guide pin 4121 and the first guide groove 5111 always have a certain degree of engagement, while also ensuring that the guide pin 4121 always moves in the preset direction along the extension direction of the first guide groove 5111.

[0114] In some embodiments, combined with Figure 7 and Figure 8 As shown, the first guide groove 5111 extends from a first position near the rotation axis of the transmission member 42 to a second position away from the rotation axis of the transmission member 42. The guide pin 4121 moves between the first and second positions to drive the pawl 411 closer to or further away from the rotation axis of the transmission member 42. When the guide pin 4121 moves along the first guide groove 5111 to the first position, the pawl 411 approaches the optical axis and is adapted to engage with the slot 321 in the aforementioned embodiment, thereby locking the movement of the lens assembly 20 relative to the body 10 along the optical axis. When the guide pin 4121 moves along the first guide groove 5111 to the second position, the pawl 411 moves away from the optical axis and is adapted to disengage from the slot 321 in the aforementioned embodiment, thereby unlocking the movement of the lens assembly 20 relative to the body 10 along the optical axis. In a specific embodiment, the optical axis of the lens assembly 20 may be collinear with the rotation axis of the transmission member 42.

[0115] In some embodiments, such as Figure 7 and Figure 8 As shown, there are multiple first guide grooves 5111, which are distributed around the circumference of the lens assembly 20. This allows them to engage with multiple claws 411 around the circumference of the lens assembly 20 and provides guidance for the claws 411, making their movement trajectories similar and their movements synchronized. When the guide pins 4121 of the multiple claws 411 move to the first position simultaneously, each claw 411 approaches the optical axis and engages with the slot 321. When the guide pins 4121 of the multiple claws 411 move to the second position simultaneously, each claw 411 moves away from the optical axis, thus disengaging from the slot 321.

[0116] In one specific embodiment, such as Figure 8As shown, the end of the first guide groove 5111 includes at least one arcuate groove 5112. The optical axis of the lens assembly 20 passes through the center of the arcuate groove 5112. When the guide pin 4121 moves along the arcuate groove 5112, it can move circumferentially around the optical axis of the lens assembly 20. When running on the arcuate groove 5112, the arcuate groove 5112 itself has no slope, and the distance between the guide pin 4121 and the optical axis of the lens assembly 20 is neither closer nor farther. Therefore, the distance between the pawl 411 on the guide pin 4121 and the optical axis of the lens assembly 20 does not change. Since the arcuate groove 5112 is located at the end of the first guide groove 5111, the guide pin 4121 can stop when it moves to the end of the arcuate groove 5112, thereby effectively preventing the user from accidentally triggering the pawl 411 and causing it to disengage from the slot 321. In a more specific embodiment, the first guide groove 5111 has a circular arc groove 5112 at each end, so that the guide pin 4121 can move into the circular arc groove 5112 regardless of which end of the first guide groove 5111 it moves to. During the sliding of the guide pin 4121 along the circular arc groove 5112, the pawl 411 will not move in a direction perpendicular to the optical axis, thus preventing the user from accidentally triggering the locking or unlocking mechanism.

[0117] Optionally, in the lens assembly 20 and the body 10 (e.g. Figure 3 , Figure 6 and Figure 23 During the relative rotation (as shown), the movement of the first locking member 41 in the direction perpendicular to the optical axis can also be guided by a guide structure provided on the transmission member 42. For example, the first locking member 41 can be clamped between the transmission member 42 and the mounting base 51. The transmission member 42 can also be provided with guide grooves distributed circumferentially, extending from a position close to the rotation axis of the transmission member 42 to a position away from the rotation axis of the transmission member 42. At this time, the first locking member 41 can be limited by the first guide groove 5111 on the mounting base 51 and can only move radially along the transmission member 42. Thus, the rotation of the transmission member 42 relative to the first locking member 41 causes the first locking member 41 to move closer to or away from the rotation axis of the transmission member 42.

[0118] In some embodiments, such as Figure 3 and Figure 9 As shown, the first locking structure 40 also includes a bottom cover 43, which is connected to the transmission member 42 and rotates together with the transmission member 42. The bottom cover 43 can cooperate with the transmission member 42 to clamp the claw 411 between them, and the claw 411 can move relative to the bottom cover 43 or the transmission member 42.

[0119] Furthermore, such as Figure 9As shown, the bottom cover 43 is provided with a second guide groove 431, which extends from a position near the rotation axis of the transmission member 42 to a position away from the rotation axis of the transmission member 42. The guide pin 4121 cooperates with both the first guide groove 5111 and the second guide groove 431. The bottom cover 43 is linked with each claw 411 with the guide pin 4121 through the second guide groove 431, so that at least a part of each claw 411 is on the same plane of motion. When the bottom cover 43 rotates together with the transmission member 42, it also drives the claws 411 to rotate, realizing the engagement or disengagement of the claws 411 relative to the slot 321. When the claws 411 move, the guide pin 4121 moves not only in the first guide groove 5111 but also in the second guide groove 431. Thus, under the combined action of the first guide groove 5111 and the second guide groove 431, the claws 411 can not only rotate along the optical axis of the lens assembly 20, but also move in a direction close to or away from the optical axis.

[0120] In some embodiments, the mounting component 50 and the first locking structure 40 are disposed on the housing 10 (e.g., ...). Figure 3 , Figure 6 and Figure 23 As shown, the mating structure 30 is disposed on the lens assembly 20, thereby simplifying the structure of the lens assembly 20, making it lighter and more compact. Furthermore, since the lens assembly 20 is a replaceable component, placing a simpler structure on a replaceable component effectively reduces costs. The larger space in the body 10 allows for the arrangement of more complex structures, such as the first locking structure 40, that cooperate with the components on the lens assembly 20. In other embodiments, the mounting component 50 and the first locking structure 40 can also be disposed on the lens assembly 20, while the mating structure 30 is disposed on the body 10.

[0121] Furthermore, in the first state and the second state, the relative position of the first locking structure 40 with respect to the body 10 changes. For example, as described in the foregoing embodiments, the relative position of the first locking structure 40 with respect to the body 10 can change at least in the direction perpendicular to the optical axis, so that the first locking structure 40 changes towards the direction closer to the optical axis or towards the direction farther from the optical axis, thereby realizing the locking and unlocking between the first locking structure 40 and the mating structure 30.

[0122] The camera 100 of this application may also omit the aforementioned mounting base 51, and the first guide portion 511 may also omit the mounting base 51 and instead be directly mounted on the body 10 or the lens assembly 20, thereby simplifying the structure.

[0123] In some embodiments of this application, the fuselage 10 (e.g.) Figure 3 , Figure 6 and Figure 23As shown, the lens assembly 20 is provided with a first guide portion 511, and the first locking structure 40 includes a first locking member 41. The first locking member 41 is provided with a second guide portion 412, which cooperates with the first guide portion 511, so that the first locking member 41 can move relative to the body 10 or the lens assembly 20 in a preset direction when rotated. In these embodiments, the first locking member 41 can still move in the preset direction through the guiding cooperation of the second guide portion 412 and the first guide portion 511.

[0124] In a specific embodiment, the first guide portion 511 includes a first guide groove 5111, the second guide portion 412 includes a guide pin 4121, and the first locking member 41 further includes a pawl 411. The guide pin 4121 is configured to engage with the first guide groove 5111 and can move along the first guide groove 5111 when the first locking member 41 rotates, thereby driving the pawl 411 to move. (See reference...) Figure 4 Each claw 411 may be provided with two guide pins 4121, which respectively cooperate with two first guide grooves 5111, thereby making the movement of the claw 411 more stable. Furthermore, the two first guide grooves 5111 corresponding to the two guide pins 4121 have different shapes, thus smoothing the movement trajectory of the claw 411 according to the different shapes of the first guide grooves 5111. The specific shapes can be set according to actual needs and are not limited here. The specific structure of the first guide groove 5111 and the cooperation structure between the guide pins 4121 and the first guide groove 5111 can be referred to the description of the foregoing embodiment, and will not be repeated here.

[0125] The specific structure of the pre-tightening structure 60 of this application and the implementation of the pre-tightening are described below.

[0126] In some embodiments of this application, such as Figure 3 and Figure 24As shown, the camera 100 also includes a pre-tightening structure 60, and a first locking structure 40 including a first locking member 41. The pre-tightening structure 60 is configured to apply a pre-tightening force along the optical axis of the lens assembly 20 to the first locking member 41 when the first locking structure 40 is in a first state, and is configured to release the pre-tightening force on the first locking member 41 during the process of the first locking structure 40 changing from the first state to the second state. In these embodiments, when the first locking structure 40 is in the first state, the pre-tightening structure 60 can press the first locking member 41 in the optical axis of the lens assembly 20, thereby stably limiting the first locking member 41 in the second mating part 32, improving the stability of the first locking member 41 when locking the lens assembly 20 and the camera body 10 in the optical axis direction. When the first locking structure 40 is in the second state, the pre-tightening structure 60 releases the pre-tightening force on the first locking member 41 in the optical axis direction of the lens assembly 20, allowing the first locking member 41 to quickly switch positions without friction, for example, allowing the first locking member 41 to quickly disengage from the slot 321 in the aforementioned embodiments.

[0127] Understandably, since the pre-tightening structure 60 can apply a pre-tightening force along the optical axis of the lens assembly 20 to the first locking member 41, and the first locking member 41 engages with the mating structure 30 in the locked state, the first locking member 41 can apply a pre-tightening force along the optical axis of the lens assembly 20 to the mating structure 30. Since the mating structure 30 and the first locking member 41 are respectively provided on the body 10 and the lens assembly 20, the pre-tightening force can make the mounting surfaces between the lens assembly 20 and the body 10 fit tightly, reducing the unexpected shaking between the lens assembly 20 and the body 10 in the locked state.

[0128] In some embodiments, such as Figure 2 As shown, the mounting component 50 is disposed on the body 10 (e.g. Figure 3 , Figure 6 and Figure 23 As shown, the mounting assembly 50 includes a positioning member 52, and at least a portion of the first locking structure 40 is disposed between the positioning member 52 and the body 10, and at least a portion of the first locking structure 40 is rotatable relative to the positioning member 52 and the body 10. The positioning member 52 limits the first locking structure 40 between itself and the body 10, ensuring a defined mounting position for the first locking structure 40, and allowing the lens assembly 20 to pass through the positioning member 52, further enabling the mating structure 30 on the lens assembly 20 to engage with the first locking structure 40. In a specific embodiment, the positioning member 52 is a positioning ring, with a through-hole in the center along the thickness direction of the positioning ring, allowing the lens assembly 20 to pass through. Figure 3 As shown, the port can also be used as part of the lens interface 11.

[0129] In some embodiments, such as Figure 10As shown, the pre-tightening structure 60 includes an elastic element 61, which is disposed between the positioning member 52 and the first locking structure 40, and is configured to provide an elastic force to the first locking structure 40 along the optical axis direction of the lens assembly 20, at least when the first locking structure 40 is in a first state. Therefore, when the first locking structure 40 is in the first state, the elastic force provided by the elastic element 61 can press the first locking member 41 tightly along the optical axis direction, improving the engagement effect between the first locking member 41 and the second mating part 32.

[0130] In some embodiments, such as Figure 3 and Figure 4 As shown, the first locking structure 40 includes a transmission member 42 and a first locking member 41. The transmission member 42 is connected to the first locking member 41, and the first locking member 41 is disposed near the body 10 of the transmission member 42 (e.g., Figure 3 , Figure 6 and Figure 23 On one side (as shown), the transmission member 42 is configured to rotate according to the relative rotation of the body 10 and the lens assembly 20; when the first locking structure 40 is in the first state, the transmission member 42 presses against the first locking member 41 along the optical axis, and the elastic member 61 is configured to apply an elastic force to the first locking member 41 through the transmission member 42 so that the first locking member 41 abuts against the mating structure 30; during the process of the first locking structure 40 changing from the first state to the second state, the transmission member 42 moves away from the first locking member 41 along the optical axis while rotating, so that a gap is generated between the transmission member 42 and the first locking member 41 along the optical axis of the lens assembly 20. At this time, even if the elastic force applied by the elastic member 61 can be transmitted to the transmission member 42, the first locking member 41 is no longer subjected to the elastic force of the elastic member 61 due to the gap between the first locking member 41 and the transmission member 42.

[0131] In some embodiments, such as Figure 10 As shown, during the transition from the first locking structure 40 to the second state, the elastic element 61 remains in a compressed state. In these embodiments, the elastic element 61 can be arranged in a ring shape along the circumference of the transmission element 42, so that the transmission element 42 is subjected to the elastic force of the elastic element 61 regardless of its rotation position. This allows the positioning element 52 to fit tightly with the relevant contact surface of the mating structure 30 of the lens assembly 20, and ensures tight fit between the contact surfaces of the positioning element 52 and the lens assembly 20, and between the first locking structure 40 and the mounting assembly 50, thereby improving the stability of the connection between the components. In a specific embodiment, both the positioning element 52 and the transmission element 42 have annular receiving grooves on their respective sides facing each other. The annular elastic element 61 can abut against the inner walls of the two receiving grooves, thereby applying an elastic force to the positioning element 52 or the transmission element 42.

[0132] In one specific embodiment, such as Figure 10 As shown, the pre-tightening structure 60 also includes two gaskets 62, both of which are annular. One gasket 62 is disposed in the receiving groove of the elastic member 61 facing the positioning member 52, and the other gasket 62 is disposed in the receiving groove of the elastic member 61 facing the transmission member 42. The gaskets 62 can make the gap between the elastic member 61 and the positioning member 52 or the transmission member 42 smaller, so that the elastic force of the elastic member 61 can be better transmitted to the positioning member 52 or to the transmission member 42.

[0133] In one specific embodiment, the elastic element 61 can be a wave spring. The wave spring is circular in shape, and its circumferential segments form a wave shape, that is, the elastic element 61 forms a continuous structure with high and low undulations along the optical axis of the lens assembly 20. When the elastic element 61 is disposed between the positioning member 52 and the transmission member 42, the positioning member 52 and the transmission member 42 clamp the elastic element 61, thereby compressing the elastic element 61.

[0134] Of course, the structure of the elastic element 61 is not limited to the above embodiment, and the elastic element 61 does not need to be compressed at all times, such as... Figure 11 As shown, the elastic element 61 can also be multiple segments. The multiple segments of the elastic element 61 are arranged at intervals along the circumference of the positioning element 52, or the multiple segments of the elastic element 61 are arranged at intervals around the rotation axis of the first locking structure 40, so that the multiple segments of the elastic element 61 can provide elastic force to the positioning element 52 and the transmission element 42 at multiple positions to achieve pre-tightening.

[0135] In these embodiments, since the elastic element 61 is designed as multiple segments, each segment of the elastic element 61 needs to be fixed to the positioning element 52 or to the transmission element 42. For example, when the multiple segments of the elastic element 61 are fixed to the positioning element 52, such as... Figure 11 As shown, one end of the multiple elastic elements 61 forms a connecting piece 611, which is fixed to the positioning member 52 by fasteners, thereby fixing the position of one end of the elastic element 61 and fixing the circumferential spacing of the elastic elements 61. Each elastic element 61 can be stably arranged along the circumferential direction and can compress and recover at a limited position, thereby providing a continuous and stable elastic force when compressed.

[0136] In one specific embodiment, the connecting piece 611 of the elastic member 61 forms a certain angle with the other parts of the elastic member 61, so that the connecting piece 611 can extend away from the optical axis, which is convenient for fixing and reduces the gap between the transmission member 42 and the positioning member 52 caused by fixing; it also allows the remaining parts of the elastic member 61 to be located in the surface where the positioning member 52 and the transmission member 42 cooperate, which is convenient for applying elastic force.

[0137] In one specific embodiment, the ends of the multiple elastic members 61 away from the connecting piece 611 form free ends, and the main body of the elastic member 61 forms at least one curved arc segment in the direction of the optical axis, so that the elastic member 61 can generate an elastic force along the direction of the optical axis after being compressed. For example, each elastic member 61 is an elastic sheet with an arc, which is thin, easy to arrange, and has sufficient elastic force after being compressed.

[0138] In some embodiments, such as Figure 12 and Figure 13 As shown, during the transition from the first locking structure 40 to the second state, the elastic element 61 changes from a compressed state to a non-compressed state. That is, the elastic element 61 is only compressed when the first locking structure 40 is in the first state, and the elastic element 61 applies an elastic force to the first locking structure 40 and the positioning element 52; while when the first locking structure 40 is in the second state, the elastic element 61 is not compressed, returns to its free state, and does not apply an elastic force to the first locking structure 40.

[0139] In some embodiments, such as Figure 14 and Figure 15 As shown, a boss 425 protrudes from the side of the transmission member 42 facing the mating structure 30. The boss 425 is higher than other parts of the transmission member 42 on the same side. When the transmission member 42 rotates, the boss 425 also rotates. When the first locking structure 40 rotates to the first state, as shown... Figure 12 As shown, the boss 425 contacts one of the elastic elements 61 and compresses the elastic element 61. The elastic element 61 also applies a certain preload force to the boss 425, thereby preloading the transmission element 42. The preload force on the transmission element 42 can be further transmitted to the mounting base 51 or the first locking element 41 in contact with it. The elastic force generated by the elastic element 61 also presses the contact surface between the positioning element 52 and the lens assembly 20, making the lens assembly 20 stable relative to the body 10. When the first locking structure 40 rotates to the second state, as Figure 13 As shown, the boss 425 disengages from one of the elastic members 61, thereby restoring the elastic member 61 to its original shape. There is no preload between the elastic member 61 and the transmission member 42, which means that the transmission member 42 no longer applies preload to the first locking member 41. The first locking member 41 can quickly change its position or state without the frictional force applied by the transmission member 42.

[0140] In some embodiments of this application, such as Figure 3 As shown, the mounting assembly 50 includes a mounting base 51, which is disposed between the body 10 and the first locking structure 40. The first locking structure 40 includes a transmission member 42 and a first locking member 41, as shown. Figure 4As shown, the mounting base 51 and / or the transmission member 42 have a ramp structure 4050. The ramp structure 4050 is configured to drive the transmission member 42 to move axially along its rotation axis according to the relative rotation of the mounting base 51 and the transmission member 42, so that the transmission member 42 is pressed against or disengaged from the first locking member 41. That is, the ramp structure 4050 can be provided on the mounting base 51, on the transmission member 42, or on both the mounting base 51 and the transmission member 42. For example, in a specific embodiment, such as Figure 4 , Figure 12 , Figure 14 and Figure 17 As shown, the inclined structure 4050 includes a first inclined surface 423 disposed on the transmission member 42. The first inclined surface 423 forms a certain angle with the main mating surface between the transmission member 42 and the mounting base 51. When the transmission member 42 rotates relative to the mounting base 51 along the first rotation direction (such as clockwise), under the action of the first inclined surface 423, the transmission member 42 can be mated to a deeper mating surface of the mounting base 51, so that the boss 425 on the transmission member 42 abuts against the elastic member 61. At this time, the first locking structure 40 is in the first state. The elastic member 61 applies an elastic force to the transmission member 42, and the transmission member 42 further transmits the elastic force to the pawl 411 and the mounting base 51, realizing the pre-tightening of the pawl 411 along the optical axis direction, and also realizing the pre-tightening of the contact surface between the transmission member 42 and the mounting base 51.

[0141] For example, in a specific embodiment, such as Figure 4 , Figure 12 , Figure 13 , Figure 15 , Figure 17 and Figure 18 As shown, the inclined structure 4050 includes a second inclined surface 512 disposed on the mounting base 51. The second inclined surface 512 is configured to decrease in slope along the first rotation direction (e.g., clockwise), so that the surfaces of the mounting base 51 on both sides of the second inclined surface 512 have a certain height difference. When the transmission member 42 rotates from the surface of the mounting base 51 upstream of the second inclined surface 512 in the first rotation direction to the second inclined surface 512, and continues to rotate to the surface of the mounting base 51 downstream of the first rotation direction, the transmission member 42 and the mounting base 51 fit more tightly, and the distance between the transmission member 42 and the pawl 411 is also closer. Under the action of the elastic force of the elastic member 61, the transmission member 42 can further transmit the elastic force to the pawl 411, so that the pawl 411 is pressed. In other embodiments, such as Figure 4As shown, the inclined structure 4050 includes a first inclined surface 423 disposed on the transmission member 42 and a second inclined surface 512 disposed on the mounting base 51. Both the first inclined surface 423 and the second inclined surface 512 are inclined downward along the direction of change of the first rotation direction. When the transmission member 42 rotates on the mounting base 51 along the first rotation direction (e.g., clockwise), the second inclined surface 512 provides a certain guidance and support for the first inclined surface 423. Conversely, when the transmission member 42 rotates on the mounting base 51 along the second rotation direction (e.g., counterclockwise), the transmission member 42 rises along the second inclined surface 512 to the higher surface of the mounting base 51, creating a certain gap between the transmission member 42 and the pawl 411, thereby disengaging the transmission member 42 from the first locking member 41 (e.g., the pawl 411).

[0142] In some embodiments, combined with Figure 3 and Figure 4 As shown, the mounting base 51 includes a first guide groove 5111, and the first locking member 41 includes a guide pin 4121 and a pawl 411. The guide pin 4121 is configured to engage with the first guide groove 5111 and can move along the first guide groove 5111 when the transmission member 42 rotates, thereby driving the pawl 411 to move. Figure 7 and Figure 8 As shown, the first guide groove 5111 includes a first part 5113 and a second part 5114. During the process of the first locking structure 40 changing from the first state to the second state, the guide pin 4121 changes from moving along the first part 5113 to moving along the second part 5114. When the guide pin 4121 moves along the extension direction of the first part 5113, the pawl 411 rotates around the rotation axis of the transmission member 42. When the guide pin 4121 moves along the extension direction of the second part 5114, the pawl 411 moves in a direction away from the rotation axis of the transmission member 42 while rotating around the rotation axis of the transmission member 42. As can be seen, when the guide pin 4121 moves along the first part 5113 and the second part 5114, the position and / or distance of the pawl 411 with the guide pin 4121 relative to the rotation axis of the transmission member 42 are different. When the pawl 411 moves along the first part 5113 with the guide pin 4121, the pawl 411 only rotates, and the distance of the pawl 411 relative to the rotation axis of the transmission member 42 does not change. This allows the pawl 411 to be held in a specific position, such as in a blocking position, so that the pawl 411 engages with the slot 321, locking the movement of the lens assembly 20 along the optical axis of the lens assembly 20. When the pawl 411 moves along the second part 5114 with the guide pin 4121, the pawl 411 can not only rotate to a certain extent, but also adjust the distance relative to the rotation axis of the transmission member 42, thus disengaging the pawl 411 from the slot 321.

[0143] In some embodiments, such as Figure 8 As shown, the first guide groove 5111 also includes a third part 5115, which is connected to the end of the second part 5114 away from the first part 5113. When the guide pin 4121 moves along the extension direction of the third part 5115, the pawl 411 rotates around the rotation axis of the transmission member 42. The third part 5115 enables the pawl 411 to be further held in the direction away from the rotation axis of the transmission member 42, which also enables the pawl 411 to be in the avoidance position. The pawl 411 disengages from the pawl groove 321, which facilitates the lens assembly 20 to be installed into or removed from the body 10 along its own optical axis.

[0144] In a specific embodiment, both the first part 5113 and the third part 5115 are arc grooves 5112, so that the centers of both arc grooves 5112 can pass through the optical axis of the lens assembly 20. Therefore, when the guide pin 4121 moves along the arc groove 5112, it can move circumferentially around the optical axis of the lens assembly 20, allowing the claw 411 to be held at a certain distance from the optical axis of the lens assembly 20, effectively preventing accidental triggering by the user. In a more specific embodiment, the arc length of the first part 5113 is greater than the arc length of the third part 5115, thus making the claw 411 more stable in the first part 5113, and consequently, making the engagement between the claw 411 and the slot 321 more stable.

[0145] The specific structure and implementation of the second locking structure 70 of this application will be described below.

[0146] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 16 and Figure 24 As shown, the camera 100 also includes a second locking structure 70, which is disposed on the lens assembly 20 or the body 10 (e.g., Figure 3 , Figure 6 and Figure 23 As shown, the lens assembly 20 is configured to lock the rotation of the lens assembly 20 relative to the camera body 10 about the optical axis of the lens assembly 20 when the relative rotation of the lens assembly 20 and the camera body 10 causes the first locking structure 40 to be in a first state. The second locking structure 70 can be disposed on the lens assembly 20 or on the camera body 10; the following description will primarily use the example of the second locking structure 70 being disposed on the camera body 10. When the second locking structure 70 is in the locked state, it limits the rotation of the lens assembly 20 relative to the camera body 10 about the optical axis of the lens assembly 20, thereby locking the lens assembly 20 when it is in place and preventing unexpected unlocking due to relative rotation between the lens assembly 20 and the camera body 10 in the locked state.

[0147] In some embodiments, such as Figure 19 , Figure 20 and Figure 25 As shown, the second locking structure 70 includes a second locking member 71 and a first reset member 72. The second locking member 71 is movable between an unlocked position and a locked position to unlock or lock the rotation of the lens assembly 20 relative to the camera body 10 about the optical axis of the lens assembly 20. The first reset member 72 is connected to the second locking member 71, as shown in the diagram. Figure 1 and Figure 21 As shown, when the first locking structure 40 is in the second state, the second locking member 71 is held in the unlocked position by the action of the first locking structure 40, thereby allowing the lens assembly 20 to rotate relative to the body 10 about the optical axis of the lens assembly 20; as Figure 2 and Figure 22 As shown, when the first locking structure 40 is in the first state, the second locking member 71 is moved from the unlocked position to the locked position by the action of the first reset member 72, thereby locking the movement of the lens assembly 20 relative to the body 10 around the optical axis of the lens assembly 20. When the second locking member 71 is not unlocked, the lens assembly 20 cannot rotate relative to the body 10, thereby greatly improving the reliability of the lens assembly 20 after it is installed in place.

[0148] In a specific embodiment, the first reset member 72 includes an elastic portion 721, which is configured to provide an elastic force that causes the second locking member 71 to move from the unlocked position to the locked position. That is, the second locking member 71 of this application is always connected to the elastic portion 721, and the elastic force provided by the elastic portion 721 causes the second locking member 71 to move toward the locked position. Only by overcoming a portion of the elastic force can the second locking member 71 move from the locked position to the unlocked position.

[0149] In a specific embodiment, such as Figure 19 and Figure 25 As shown, the second locking member 71 includes a locking pin 711, which is configured to engage with the first locking structure 40 when the first locking structure 40 is in a first state to restrict rotation of the first locking structure 40. In these embodiments, the locking pin 711 is connected to the aforementioned elastic portion 721. Under the action of the elastic portion 721, the locking pin 711 extends and limits the first locking structure 40, preventing the first locking structure 40 from rotating, thus preventing the mating structure 30 from rotating, and consequently preventing the lens assembly 20 from rotating relative to the body 10. In one embodiment, as... Figure 14 and Figure 15 As shown, the transmission member 42 is provided with a radially protruding stop portion 424, which, when the first locking structure 40 is in the second state, such as Figure 21As shown, the orthographic projection of the locking pin 711 on the transmission member 42 is located within the stop portion 424, that is, the stop portion 424 and the locking pin 711 abut against each other, causing the locking pin 711 to overcome part of the elastic force of the elastic portion 721 and move away from the stop portion 424; as Figure 22 As shown, when the first locking structure 40 is in the first state, the orthogonal projection of the locking pin 711 on the transmission member 42 is located outside the stop portion 424. The elastic portion 721 recovers its elasticity, driving the locking pin 711 to move toward the locking position. The locking pin 711 is limited to the side of the stop portion 424, preventing the stop portion 424 from continuing to rotate along the rotation axis of the transmission member 42, thereby realizing the locking of the locking pin 711 to limit the rotation of the transmission member 42.

[0150] In some embodiments, such as Figure 3 , Figure 19 , Figure 20 , Figure 24 and Figure 25 As shown, the second locking structure 70 also includes an operating member 73, which is connected to the second locking member 71. When the operating member 73 is subjected to an external force, it drives the second locking member 71 to move, causing the second locking member 71 to move from the locked position to the unlocked position. In these embodiments, the external force can be a pushing force applied by a human hand or a mechanically applied pushing force. When the operating member 73 is subjected to force, the force of the operating member 73 is applied to the second locking member 71, causing the second locking member 71 to overcome part of the force of the elastic part 721, further compressing the elastic part 721, and thus causing the second locking member 71 to change to the unlocked position. In specific embodiments, such as... Figure 19As shown, the operating member 73 includes a force-applying buckle 731 and a pressing part 732. The force-applying buckle 731 is provided on the side of the pressing part 732 facing the second locking member 71. The second locking member 71 is also provided with a guide block 712. The pressing part 732 is convenient for applying external force. The force-applying buckle 731 can cooperate with the guide block 712. When the force-applying buckle 731 presses against the guide block 712, it can drive the entire second locking member 71 to switch to the unlocked position. In a more specific embodiment, the force-applying buckle 731 has an inclined third slope 7311, and the guide block 712 has a fourth slope 7121. When a pressing force is applied to the pressing part 732, the force-applying buckle 731 moves toward the guide block 712, and the third slope 7311 and the fourth slope 7121 abut against each other, allowing the guide block 712 to move toward the elastic part 721. Thus, the second locking member 71 can overcome part of the force exerted by the elastic part 721, thereby unlocking the second locking structure 70. In other embodiments, to make the force applied by the force-applying buckle 731 to the guide block 712 more balanced, two force-applying buckles 731 can be horizontally spaced on the pressing part 732, and two guide blocks 712 can be correspondingly provided on the second locking member 71. When force is applied to the pressing part 732, the two force-applying buckles 731 apply pressure to the two guide blocks 712 respectively, thereby unlocking the second locking member 71.

[0151] In some embodiments, such as Figure 24 and Figure 25 As shown, the second locking structure 70 also includes a second reset member 75, which is connected to the operating member 73. When the operating member 73 is not subjected to external force, the second reset member 75 drives the operating member 73 to perform a reset movement. In these examples, by setting the second reset member 75, when an external force is applied to the operating member 73, the second reset member 75 is compressed and stores force; after the external force is removed, the second reset member 75 rebounds and drives the operating member 73 to reset, making it convenient to apply force to the operating member 73 again, improving the ease of use of the operating member 73, and thus facilitating the switching of the second locking member 71 of the second locking structure 70 between the unlocked and locked positions. In some specific examples, the second reset member 75 is a rectangular spring; in other examples, the second reset member 75 can also be in the form of a spring sheet, etc., without specific limitations.

[0152] In some examples, such as Figure 24 and Figure 25As shown, the second locking structure 70 also includes a sensor 76 and a detector 77. One of the sensor 76 and the detector 77 is disposed on the second locking member 71, and the other of the sensor 76 and the detector 77 is fixedly disposed relative to the lens assembly 20 or the camera body 10. When the lens assembly 20 is mounted on the camera body 10, since the second locking member 71 can switch between a locked position and an unlocked position, the sensor 76 (or detector 77) disposed on the second locking member 71 can move accordingly. The detector 77 (or sensor 76) disposed on the lens assembly 20 or the camera body 10 can detect the position change of the sensor 76, thereby executing the corresponding control program.

[0153] Furthermore, the detection element 77 is configured to detect that the sensing element 76 moves to the locked position following the second locking element 71, instructing the camera body 10 to supply power to the lens assembly 20. When the second locking element 71 is in the locked position, the camera body 10 and the lens assembly 20 are installed in place, and the first locking structure 40 and the second locking structure 70 are simultaneously locked, making it difficult for the lens assembly 20 to detach from the camera body 10, and the relative positions of the two are relatively stable. At this time, when the camera body 10 supplies power to the lens assembly 20, the power supply is stable, allowing the various electronic components on the lens assembly 20 to obtain a stable power source. This effectively avoids short circuits caused by contact and energization between conductive components when the lens assembly 20 is not yet installed in place, or shortened lifespan of electronic components due to brief contact and conductivity.

[0154] In some specific examples, the detection element 77 is disposed on the body 10, and the sensing element 76 is disposed on the second locking element 71, such that the locking pin 711 of the second locking element 71 extends relative to the body 10 to the relevant part of the lens assembly 20 (e.g., in the aforementioned examples). Figure 22 When the second locking member 71 is in the locked position (side of the stop part 424), the detection member 77 can further execute the subsequent program when it detects the signal of the sensing member 76, so that the body 10 can stably supply power to the lens assembly 20.

[0155] In some alternative examples, the detection element 77 is a photoelectric sensor, and the sensing element 76 is a light-shielding element or a light source. Taking a light-shielding element as an example, when the second locking element 71 is in the unlocked or locked position, the degree of light blocking by the sensing element 76 on the photoelectric sensor is different, thereby enabling the detection element 77 to sense the change in light and convert the light signal into an electrical signal, thus determining whether the second locking element 71 is in the unlocked or locked position. Of course, the detection element 77 and the sensing element 76 can also be other types of electronic devices. For example, the detection element 77 can be a position sensor, and the sensing element 76 can be a specific component to be measured on the second locking element 71. The sensing element 76 can also be a part of the structure of the second locking element 71. No specific limitations are imposed here.

[0156] In some embodiments, such as Figure 19 , Figure 20 and Figure 25 As shown, the second locking structure 70 also includes a locking seat 74, which is mounted on the mounting base 51, thereby fixing the position of the second locking structure 70 relative to the mounting assembly 50. The locking seat 74 houses an elastic portion 721 and a second locking member 71. The operating member 73 can move closer to or further away from the locking seat 74 to achieve unlocking or locking operations. One end of the elastic portion 721 is connected to the locking seat 74, and the other end of the elastic portion 721 is connected to the second locking member 71. The elastic portion 721 usually drives the locking pin 711 to move away from the locking seat 74, so that the locking pin 711 extends a longer distance, thereby locking at the stop portion 424 of the transmission member 42 in the aforementioned embodiment. In some specific examples, such as Figure 25 As shown, the locking base 74 is provided with the aforementioned detection element 77, and the second locking member 71 is provided with the aforementioned sensing element 76. Thus, when the second locking member 71 moves relative to the locking base 74 and switches between the locked position and the unlocked position, the detection element 77 can detect the position change of the sensing element 76 and realize the signal change of the detection element 77 itself, thereby realizing the subsequent execution program.

[0157] In existing technologies, the electrical connection between the lens and the camera body is often achieved through a contact-connector interface. This requires the contacts to mate with the connector in a preset position, necessitating alignment of the lens and camera body with mounting marks to ensure the contacts are properly positioned and engaged with the connector. This reduces the ease of installation.

[0158] The structure and electrical connection implementation of the conductive strip 81 and electrical contact 82 of this application will be described below.

[0159] In some embodiments of this application, such as Figure 3 and Figure 24 As shown, the camera 100 also includes a conductive strip 81 and electrical contacts 82. The conductive strip 81 is disposed on the body 10 (e.g., Figure 3 , Figure 6 and Figure 23 As shown, one of the body 10 and the lens assembly 20, an electrical contact 82 is disposed on the other of the body 10 and the lens assembly 20, and a conductive strip 81 cooperates with the electrical contact 82 to enable contact-type electrical connection between the body 10 and the lens assembly 20; wherein, the conductive strip 81 extends circumferentially along the body 10 or the lens assembly 20 and encloses to form a closed shape. In these embodiments, the conductive strip 81 may be disposed on the body 10, in which case the electrical contact 82 is disposed on the lens assembly 20; as shown Figure 23 As shown, the conductive strip 81 can also be disposed on the lens assembly 20, and as... Figure 3As shown, the electrical contact 82 is disposed on the body 10. In the following embodiments, the example of the conductive strip 81 being disposed on the lens assembly 20 and the electrical contact 82 being disposed on the body 10 is used for illustration. In some embodiments, such as... Figure 3 As shown, the camera body 10 includes an electrical connector 13, on which multiple electrical contacts 82 are spaced apart along the optical axis. This facilitates the contact and electrical connection between the electrical contacts 82 and the conductive strip 81 after the lens assembly 20 is mounted onto the camera body 10. Since the conductive strip 81 forms a circumferentially closed shape, contact and conduction between the conductive strip 81 and the electrical contacts 82 can be achieved regardless of the angle at which the lens assembly 20 is mounted onto the camera body 10, thus realizing the electrical connection and / or data transmission between the camera body 10 and the lens assembly 20, improving the ease of installation of the lens assembly 20.

[0160] In some embodiments, the conductive strip 81 is annular, thereby enabling it to engage with the electrical contact 82 at all circumferential points.

[0161] In a specific embodiment, there are multiple conductive strips 81 and multiple electrical contacts 82, with each conductive strip 81 and electrical contact 82 arranged one-to-one along the optical axis of the lens assembly 20. The multiple conductive strips 81 and multiple electrical contacts 82 ensure that each conductive strip 81 corresponds to at least one electrical contact 82, achieving electrical connection between the electrical contact 82 and the conductive strip 81, thereby achieving electrical connection between the lens assembly 20 and the camera body 10. Since the lens assembly 20 itself has a relatively long space along the optical axis, it has a large arrangement space along the optical axis. When the electrical contacts 82 and conductive strips 81 are arranged along the optical axis, the internal space of the lens assembly 20 can be fully utilized, without occupying more space perpendicular to the optical axis of the lens assembly 20. This results in efficient space utilization and stable electrical contact connection.

[0162] In some embodiments of this application, such as Figure 26 , Figure 27 As shown, the fuselage 10 includes a connector 14, which is used to connect with... Figure 28 The lens assembly 20 is engaged with the connector 14, which is connected to the first locking structure 40. The connector 14 is provided with multiple electrical contacts 82, such as... Figure 24 As shown, the lens assembly 20 is provided with multiple conductive strips 81. In these examples, the first locking structure 40 is mounted on the body 10 by being mounted on the connector 14. When the lens assembly 20 is mounted relative to the body 10, the multiple conductive strips 81 on the lens assembly 20 can make contact with the multiple electrical contacts 82 on the connector 14, thereby enabling the body 10 to supply power and transmit electrical signals to the lens assembly 20.

[0163] In a specific example, connector 14 is a connecting ring. Connector 14 can be sleeved on the outside of lens assembly 20. Connector 14 can shield the structure with multiple conductive strips 81 on lens assembly 20, providing a certain degree of protection for the electrical connection parts of lens assembly 20. It also facilitates the multiple electrical contacts 82 on connector 14 to make electrical contact with the corresponding conductive strips 81.

[0164] In some examples, such as Figure 27 As shown, one or more electrical contacts 82 on the connector 14 are spaced apart along the sleeve direction of the connecting ring and the lens assembly 20; as Figure 24 As shown, multiple conductive strips 81 are spaced apart along the optical axis of the lens assembly 20, and at least one electrical contact 82 contacts one of the conductive strips 81, so that after the lens assembly 20 is installed in place, each conductive strip 81 can form an electrical connection with one or more electrical contacts 82.

[0165] In other embodiments, the electrical contacts 82 and conductive strip 81 may be omitted. For example, a transmitting coil and a receiving coil (not shown) can be used. That is, the camera 100 also includes a transmitting coil and a receiving coil, with the transmitting coil disposed on one of the camera body 10 and the lens assembly 20, and the receiving coil disposed on the other. The transmitting coil and the receiving coil cooperate to enable a non-contact electrical connection between the camera body 10 and the lens assembly 20. In this case, the lens assembly 20 can also be mounted on the camera body 10 at any angle, and the transmitting coil and the receiving coil can then achieve radio signal transmission.

[0166] In some embodiments of this application, such as Figure 28 , Figure 29 As shown, the body 10 includes a connector 14, and the lens assembly 20 has a boss structure 22. The lens assembly 20 is installed on the body 10, and the boss structure 22 abuts against the connector 14. The boss structure 22, in cooperation with the connector 14, limits the maximum screw-in depth of the lens assembly 20 relative to the body 10 and ensures a relatively stable fit between the lens assembly 20 and the body 10, preventing the lens assembly 20 from constantly wobbling relative to the body 10 after installation. It also facilitates the positioning and engagement of the aforementioned electrical contacts 82 and conductive strip 81.

[0167] In some examples, such as Figure 24 As shown, camera 100 also includes a seal 90, such as Figure 24 and Figure 30As shown, the boss structure 22 and the connector 14 are sealed together by the seal 90, so that after the lens assembly 20 is installed relative to the body 10, the contact surfaces of the two are sealed, effectively preventing water or dust from entering the space between the lens assembly 20 and the body 10, thereby effectively protecting the electrical connection structure between the lens assembly 20 and the body 10, effectively extending the service life of the electrical connection structure, making the working environment of the electrical connection structure more stable, and effectively improving the working performance of the electrical connection structure.

[0168] In some examples, such as Figure 30 As shown, the seal 90 is connected to the boss structure 22, allowing the seal 90 and lens assembly 20 to be installed together as a single unit on the connector 14 and the body 10, eliminating the need for separate installation of the seal 90. In a specific example, the sidewall of the lens assembly 20 protrudes away from the optical axis of the lens assembly 20 to form the boss structure 22. The boss structure 22 is spaced a certain distance from the conductive strip 81. The seal 90 is connected to the bottom wall of the boss structure 22, allowing the portion of the lens assembly 20 with the conductive strip 81 to extend into the connector 14. The portion of the lens assembly 20 from the boss structure 22 away from the conductive strip 81 is located on the outside of the connector 14, with the seal 90 abutting against the end face of the connector 14.

[0169] In other examples, the seal 90 is attached to the connector 14. This makes the boss structure 22 and the connector 14 an integral structure, facilitating installation with the lens assembly 20 without requiring the seal 90 to be installed separately.

[0170] In a specific example, the connector 14 is a connecting ring, and the seal 90 is a sealing ring disposed on the bottom surface of the boss structure 22. When the lens assembly 20 is installed on the body 10, the seal 90 contacts at least a portion of the end face of the connector 14 to achieve sealing between the lens assembly 20 and the body 10.

[0171] The following describes yet another camera 100 of this application.

[0172] This application proposes a camera 100, such as Figure 3 As shown, it includes: fuselage 10 (e.g. Figure 3 , Figure 6 , Figure 23 and Figure 24 (as shown), lens assembly 20, multiple conductive strips 81 and multiple electrical contacts 82.

[0173] Among them, such as Figure 3 and Figure 6 As shown, the camera body 10 is provided with a lens interface 11, which can be used to insert the lens assembly 20.

[0174] The lens assembly 20 is configured to be detachably mounted on the lens interface 11.

[0175] Multiple conductive strips 81 are disposed on one of the camera body 10 and the lens assembly 20; multiple electrical contacts 82 are disposed on the other of the camera body 10 and the lens assembly 20, and correspond one-to-one with the multiple conductive strips 81 to enable electrical connection between the camera body 10 and the lens assembly 20. That is, when the multiple conductive strips 81 are disposed on the lens assembly 20, the multiple electrical contacts 82 are disposed on the camera body 10; when the multiple conductive strips 81 are disposed on the camera body 10, the multiple electrical contacts 82 are disposed on the lens assembly 20.

[0176] The conductive strip 81 is ring-shaped, and multiple conductive strips 81 and multiple electrical contacts 82 are arranged one-to-one along the optical axis of the lens assembly 20. That is, each conductive strip 81 is set as a closed ring structure on the lens interface 11 or the lens assembly 20; each conductive strip 81 can be connected to at least one electrical contact 82.

[0177] As can be seen from the above, when the lens assembly 20 is installed on the lens interface 11, since the multiple conductive strips 81 extend circumferentially and form a closed shape, the electrical contact 82 can make alignment contact with the corresponding conductive strip 81 regardless of the angle from which the lens assembly 20 is installed on the lens interface 11. This enables the electrical connection between the camera body 10 and the lens assembly 20 after installation, which is beneficial for the lens assembly 20 and the camera body 10 to perform real-time data transmission after installation.

[0178] The lens assembly 20 itself has a long distance along the optical axis, and multiple conductive strips 81 and multiple electrical contacts 82 are arranged along the optical axis, which can reduce the space occupied by the body 10 or the lens assembly 20 along the direction perpendicular to the optical axis, effectively improve the space utilization, and achieve reliable electrical connection. It can effectively prevent poor contact caused by a single point contact, and improve the speed, reliability and accuracy of data transmission.

[0179] In some embodiments of this application, the camera 100 further includes: a mating structure 30 and a first locking structure 40, wherein the mating structure 30 is disposed on the lens assembly 20 and the body 10 (e.g., Figure 3 , Figure 6 and Figure 23As shown, a first locking mechanism is disposed on the other of the camera body 10 and the lens assembly 20. A first locking structure 40 is configured to move in response to the relative rotation of the camera body 10 and the lens assembly 20, and to be in either a first state or a second state. In the first state, the first locking structure 40 engages with the cooperating structure 30 to lock the movement of the lens assembly 20 relative to the camera body 10 along the optical axis. In the second state, the first locking structure 40 disengages from the cooperating structure 30 to unlock the movement of the lens assembly 20 relative to the camera body 10 along the optical axis. By configuring the first locking structure 40 and the cooperating structure 30, when relative rotation occurs between the camera body 10 and the lens assembly 20, the first locking structure 40 switches states, thereby enabling the engagement or disengagement of the first locking structure 40 with the cooperating structure 30, simplifying operation.

[0180] In these embodiments, the camera 100 can also use the relevant structures of the camera 100 in the foregoing embodiments, such as the body 10, lens assembly 20, mating structure 30, first locking structure 40, inclined surface structure 4050, mounting assembly 50, pre-tightening structure 60, second locking structure 70, etc., without conflict. These specific structural settings and descriptions will not be repeated here.

The mobile platform 1000 may also be an amphibious mobile platform 1000, such as a flying car.
