Description

Technical Field

[0001] This application relates to the field of optical product technology, and more specifically, to an optical camera and electronic device. Background Technology

[0002] In modern space imaging and XR photography systems, a core requirement is the ability to quickly connect various lenses to the main unit to meet the optical requirements of different shooting scenarios. Traditional photography systems typically rely on mechanical clips for lens mounting and dismounting; however, existing mechanical quick-release clips depend on precise mechanical fits, and wear occurs with repeated disassembly, gradually reducing their alignment accuracy. Furthermore, when the equipment is subjected to vibration or significant movement, the mechanical locking structure may loosen or experience stress fatigue, leading to optical axis misalignment, image distortion, or even the risk of the lens falling off.

[0003] To address these shortcomings, some solutions attempt to improve lens changing efficiency using magnetic alignment or semi-mechanical quick-release structures. However, most existing magnetic interfaces cannot dynamically adjust the magnetic force and lack effective shock resistance or anti-interference capabilities, making them susceptible to environmental vibrations and thus making it difficult to guarantee their reliability.

[0004] In view of this, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0028] Reference Figures 1-4 As shown, according to one embodiment of this application, an optical camera 1 is provided. The optical camera 1 includes a main unit 11 and a lens 12. The main unit 11 has a first connection end 111, and an electromagnetic module 112 is disposed on the first connection end 111. The lens 12 has a second connection end 121, and a magnetic element 122 is disposed on the lens 12 near its second connection end 121. The electromagnetic module 112 and the magnetic element 122 can attract each other to connect the main unit 11 and the lens 12. It also includes a control unit 13, which is signal-connected to the electromagnetic module 112. The control unit 13 can adjust the current value supplied to the electromagnetic module 112 within a preset range. Optionally, for example, the control unit 13 is located in the host 11; or, the control unit 13 can also be located in the electronic device to which the optical camera is applied, that is, the optical camera and the electronic device share the control unit.

[0029] In the optical camera provided in this application embodiment, the electromagnetic module 112, which is provided at the first connection end 111 of the host 11, and the magnetic component 122, which is provided near the second connection end 121 of the lens 12, attract each other, thereby realizing the connection between the host 11 and the lens 12. Its structure is simple and the connection is convenient. Furthermore, the control unit 13 is provided on the host 11 and is signal-connected to the electromagnetic module 112. The control unit 13 can adjust the current value passed into the electromagnetic module 112 within a preset range, thereby controlling the magnetic field strength generated by the electromagnetic module 112, and thus adjusting the magnetic attraction force of the electromagnetic module 112 on the magnetic component 122, that is, adjusting the connection force of the host 11 to the lens 12, thereby meeting the connection force requirements of the host 11 to the lens 12 under different usage scenarios and improving the flexibility of camera use.

[0030] Furthermore, the optical camera provided in this application embodiment significantly reduces size and weight compared to conventional cameras using a PL mount, making it particularly suitable for mobile devices such as drones or head-mount displays.

[0031] Reference Figure 1 As shown, in one embodiment, the host 11 is provided with an acceleration sensor 14, which is signal-connected to the control unit 13. The acceleration sensor 14 is configured to measure the acceleration value of the optical camera and transmit it to the control unit 13. The control unit 13 adjusts the current value supplied to the electromagnetic module 112 according to the acceleration value fed back by the acceleration sensor 14.

[0032] In this specific example, the host unit 11 is equipped with an accelerometer 14, which is signal-connected to the control unit 13. The accelerometer 14 measures the acceleration value of the optical camera and transmits it to the control unit 13. The control unit 13 adjusts the current value supplied to the electromagnetic module 112 based on the feedback acceleration value. This allows for dynamic adjustment of the magnetic attraction force of the electromagnetic module 112 on the magnetic component 122 according to the camera's operating state (e.g., different acceleration values ​​under different intensities of vibration or impact). When the camera is subjected to a large external force, the magnetic attraction force is enhanced, preventing the lens from accidentally detaching and improving the camera's safety and reliability under complex operating conditions. That is, when the acceleration value measured by the accelerometer 14 increases, the control unit 13 increases the current value supplied to the electromagnetic module 112, thereby ensuring that the host unit 11 and the lens 12 are stably engaged and will not detach. Conversely, when the acceleration value measured by the accelerometer 14 decreases, the control unit 13 decreases the current value supplied to the electromagnetic module 112, thereby saving energy.

[0033] Reference Figure 3 As shown, in one embodiment, the optical camera further includes a Hall sensor 15 disposed at the electromagnetic module 112, the Hall sensor 15 being configured to detect the position of the lens 12.

[0034] In this specific example, a Hall sensor 15 is configured at the electromagnetic module 112 to detect the position of the lens 12. For example, the Hall sensor 15 is signal-connected to the control unit 13. When the Hall sensor 15 detects that the lens 12 is close to the host 11 (e.g., when the distance between the lens 12 and the host 11 is less than or equal to a preset distance), the control unit 13 activates the electromagnetic module 112 (by supplying current to the electromagnetic module 112) based on the information fed back by the Hall sensor 15. Furthermore, the Hall sensor 15 can accurately determine whether the lens 12 is correctly installed and whether the lens 12 has shifted during camera operation. This provides a basis for the control unit 13 to further adjust the current value of the electromagnetic module 112 based on the position information of the lens 12, ensuring the stability and accuracy of the connection between the lens 12 and the host 11.

[0035] Reference Figure 1As shown, in one embodiment, the magnetic element 122 is a ring-shaped permanent magnet, which is installed on the inner wall of the lens 12 near its second connection end 121.

[0036] In this specific example, the magnetic component 122 is designed as a ring-shaped permanent magnet and installed on the inner wall of the lens 12 near the second connection end 121. This structure can make the magnetic field distribution between the magnetic component 122 and the electromagnetic module 112 more uniform, which is beneficial to improving the stability and uniformity of the magnetic attraction force. At the same time, the ring structure can also save space to a certain extent and optimize the internal structural layout of the camera.

[0037] Reference Figure 1 As shown, in one embodiment, the optical camera further includes an optical communication module 16 and a calibration data storage module 17. The optical communication module 16 is disposed on the host 11, and the calibration data storage module 17 is disposed on the lens 12. When the host 11 and the lens 12 are interconnected, the optical communication module 16 is used to read and transmit the optical parameters of the lens 12 stored in the calibration data storage module 17.

[0038] In this specific example, an optical communication module 16 and a calibration data storage module 17 are configured. The optical communication module 16 is located on the host 11, and the calibration data storage module 17 is located on the lens 12. When the host 11 and the lens 12 are interconnected, the optical communication module 16 can read and transmit the optical parameters stored in the calibration data storage module 17, realizing the automatic synchronous transmission of lens optical parameters. This reduces the need for manual adjustments, greatly improves the convenience of lens replacement, and enhances the efficiency of camera use. For example, the calibration data storage module 17 can be mounted on the magnetic component 122.

[0039] For example, the optical communication module 16 transmits the read optical parameters to the main controller, and the main controller controls the lens 12 to rotate according to the acquired optical parameters in order to achieve the purpose of automatic lens calibration.

[0040] In one embodiment, the optical communication module 16 includes a vertical cavity surface-emitting laser and a photodetector.

[0041] In this specific example, the optical communication module 16 uses a vertical-cavity surface-emitting laser (VCSEL) and a photodetector. The VCSEL has advantages such as small size, easy integration, high modulation rate, and good beam quality. The photodetector can efficiently receive optical signals and convert them into electrical signals. This combination is conducive to the optical communication module achieving stable and efficient optical communication functions within the limited space of the camera, and quickly and accurately transmitting lens optical parameters.

[0042] Reference Figure 1As shown, in one embodiment, the optical communication module 16 is located on the central axis of the lens 12.

[0043] In this specific example, the optical communication module 16 is placed on the central axis of the lens. This arrangement makes the optical path transmission between the optical communication module 16 and the lens more direct and stable, reduces the loss and interference of optical signals during transmission, improves the accuracy and reliability of optical communication, and ensures that the optical parameters of the lens can be accurately read and transmitted by the optical communication module 16.

[0044] Reference Figure 1 , Figure 4 As shown, in one embodiment, the optical camera further includes a mechanical connection assembly, which includes a limiting hole 110 opened in the host 11 and a limiting pin 120 disposed in the lens 12. When the host 11 and the lens 12 are connected to each other, the limiting pin 120 is inserted into the limiting hole 110.

[0045] In this specific example, a mechanical connection component is provided, including a limiting hole 110 on the main unit 11 and a limiting pin 120 on the lens 12. When the main unit 11 and the lens 12 are connected to each other, the limiting pin 120 is inserted into the limiting hole 110. This mechanical connection method provides additional physical fixation for the connection between the lens 12 and the main unit 11. Even if the electromagnetic adsorption fails or malfunctions, the lens can be prevented from falling off through the mechanical connection, which increases the safety and reliability of the camera connection.

[0046] For example, the main unit 11 includes a first main body 114 and a first connecting end 111, and a limiting hole 110 is formed in the first main body 114; the lens 12 includes a second main body 124 and a second connecting end 121, and a limiting pin 120 is disposed in the second main body 124.

[0047] Reference Figure 4 As shown, in one embodiment, the limiting pin 120 includes a limiting part 1201 and a plugging part 1202. The limiting part 1201 is installed on the lens 12, one end of the plugging part 1202 is connected to the limiting part 1201, and the other end of the plugging part 1202 is used to plug into the limiting hole 110. The mechanical connection assembly also includes a spring 123, which is sleeved on the outside of the insertion part 1202, and one end of the spring 123 is connected to the limiting part 1201. When the host 11 and the lens 12 are connected to each other, the other end of the spring 123 abuts against the host 11.

[0048] In this specific example, the limiting pin 120 includes a limiting part 1201 and a plug-in part 1202. The limiting part 1201 has a larger outer diameter and is mounted on the second main body part 124 of the lens 12. The plug-in part 1202 has a smaller outer diameter and is used to plug into the limiting hole 110. Furthermore, the spring 123 is sleeved on the outside of the plug-in part 1202 and one end is connected to the limiting part 1201. When the main body 11 is connected to the lens 12, the other end of the spring 123 abuts against the first main body part 114 of the main body 11. The spring 123 can play a role in buffering and pre-tightening, making the connection between the limiting pin 120 and the limiting hole 110 more stable and reliable. At the same time, it can also absorb vibration and impact to a certain extent, reduce damage to the mechanical connection structure, and further improve the stability and durability of the mechanical connection.

[0049] Reference Figure 4 As shown, in one embodiment, the mechanical connection assembly further includes a limiting platform 113, which is disposed on the host 11 and located beside the limiting hole 110. When the host 11 and the lens 12 are connected to each other, the limiting platform 113 is used to stop the limiting part 1201.

[0050] In this specific example, the first main body 114 of the host 11 is provided with a limiting platform 113 around the limiting hole 110. When the host 11 is connected to the lens 12, the limiting platform 113 is used to stop the limiting part 1201 of the limiting pin 120. This can further limit the movement range of the limiting pin 120 and prevent the limiting pin 120 from being inserted too much in the limiting hole 110 and causing damage to the host 11.

[0051] According to another embodiment of this application, an electronic device is provided, the electronic device including an optical camera 1 as described above; a host 11 is integrated into the body of the electronic device. For example, the electronic device is an XR photography system.
