Description

Technical Field

[0001] This disclosure relates to a lens barrel assembly having enhanced support between lens barrels and an electronic device including therein. Background Technology

[0002] The services or functions provided by electronic devices are being expanded in a diverse range. In addition, applications that can be executed on electronic devices are being developed in a variety of ways.

[0003] To take a photograph, an electronic device may include a camera module. The camera module may include multiple lens barrels to adjust the focal length for magnifying a target object. The multiple lens barrels move back and forth to adjust the focal length. Wearable devices can be examples of electronic devices equipped with such a camera module.

[0004] Wearable devices have been developed to enhance the practical value of electronic devices and meet various user needs. Wearable devices can be electronic devices that can be attached to or detached from a user's body or clothing. Examples of wearable devices include head-mounted displays (HMDs). HMDs can provide users with virtual reality (VR), augmented reality (AR), or mixed reality (MR). HMDs can, for example, provide users with an actual screen displayed through glasses that act as a monitor, or a virtually created screen or a screen captured by a camera.

[0005] HMDs can provide a lens assembly between the display and the eye to provide the user with a larger and clearer screen. The lens assembly may include lenses and at least two or more lens barrels in which the lenses are fixed. The combined lens barrels move in a forward and backward direction to adjust the focal length between the lenses fixed to the lens barrels. For this purpose, any one of the at least two or more lens barrels may be provided with a protruding movable pin, and another lens barrel may have an engraved recessed path corresponding to the movable pin, where the pin can contact and move; this path may be referred to as a cam path. The cam path may widen outward while maintaining a predetermined angle.

[0006] When the HMD is dropped to the ground or subjected to an external impact, the assembled lens barrels will separate. In other words, the moving pins connected to the cam path can disengage from the cam path. Therefore, as the angle of the cam path narrows, the coupling force between the lens barrels increases.

[0039] Embodiments of this disclosure are described in detail below with reference to the accompanying drawings, enabling those skilled in the art to readily practice this disclosure. However, this disclosure may be implemented in various other forms and is not limited to the embodiments set forth herein. Throughout the specification and drawings, the same or similar reference numerals may be used to refer to the same or similar elements. Furthermore, for clarity and brevity, well-known functions and configurations in the drawings and related descriptions are not described.

[0040] Figure 1 This is a block diagram illustrating an electronic device 101 in a network environment 100 according to an embodiment of the present disclosure. (See also:) Figure 1Electronic device 101 in network environment 100 can communicate with electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or with at least one of electronic device 104 or server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an example, electronic device 101 can communicate with electronic device 104 via server 108. According to embodiments, electronic device 101 may include a processor 120, memory 130, input module 150, sound output module 155, display module 160, audio module 170, sensor module 176, interface 177, connection terminal 178, haptic module 179, camera module 180, power management module 188, battery 189, communication module 190, user identification module (SIM) 196, or antenna module 197. In embodiments, at least one of the above components (e.g., connection terminal 178) may be omitted from electronic device 101, or one or more other components may be added to electronic device 101. In some implementations, some of the components described above (e.g., sensor module 176, camera module 180, or antenna module 197) may be integrated into a single integrated component (e.g., display module 160).

[0041] Processor 120 may run software (e.g., program 140) to control at least one other component (e.g., hardware or software component) of electronic device 101 connected to processor 120, and may perform various data processing or calculations. According to an example, as at least part of the data processing or calculation, processor 120 may store commands or data received from another component (e.g., sensor module 176 or communication module 190) in volatile memory 132, process the commands or data stored in volatile memory 132, and store the resulting data in non-volatile memory 134. According to an example, processor 120 may include a main processor 121 (e.g., central processing unit (CPU) or application processor (AP)) or an auxiliary processor 123 (e.g., graphics processing unit (GPU), neural processing unit (NPU), image signal processor (ISP), sensor central processor, or communication processor (CP)) that is operationally independent of or combined with the main processor 121. For example, when electronic device 101 includes a main processor 121 and a subprocessor 123, the subprocessor 123 may be configured to use less power than the main processor 121, or may be configured to be dedicated to a specific function. The subprocessor 123 may be implemented separately from the main processor 121, or may be implemented as part of the main processor 121.

[0042] When the main processor 121 is inactive (e.g., in sleep) state, the auxiliary processor 123 (rather than the main processor 121) can control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190), or when the main processor 121 is active (e.g., running an application), the auxiliary processor 123 can work with the main processor 121 to control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190). According to embodiments, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., camera module 180 or communication module 190) functionally associated with the auxiliary processor 123. According to an example, the auxiliary processor 123 (e.g., a neural processing unit) may include hardware architecture dedicated to artificial intelligence model processing. Artificial intelligence models can be generated through machine learning. For example, such learning can be performed via electronic device 101 where artificial intelligence is performed or via a separate server (e.g., server 108). The learning algorithm can include, but is not limited to, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning. The artificial intelligence model can include multiple layers of artificial neural networks. The artificial neural network can be a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), or a deep Q-network, or a combination of two or more thereof, but is not limited thereto. Additionally or optionally, the artificial intelligence model can include software structures in addition to hardware structures.

[0043] Memory 130 may store various data used by at least one component of electronic device 101 (e.g., processor 120 or sensor module 176). The various data may include, for example, software (e.g., program 140) and input or output data for commands associated with it. Memory 130 may include volatile memory 132 or non-volatile memory 134.

[0046] The sound output module 155 can output sound signals to the outside of the electronic device 101. The sound output module 155 may include, for example, a speaker or a receiver. The speaker can be used for general purposes such as playing multimedia or playing records. The receiver can be used to receive incoming calls. According to an embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0047] Display module 160 can visually provide information to the outside of electronic device 101 (e.g., to a user). Display 160 may include, for example, a display, a holographic device, or a projector, and control circuitry for controlling a respective one of the display, holographic device, and projector. According to an embodiment, display 160 may include a touch sensor configured to detect a touch or a pressure sensor configured to measure the intensity of the force generated by the touch.

[0048] The audio module 170 can convert sound into electrical signals and vice versa. According to an embodiment, the audio module 170 can obtain sound via the input module 150, or output sound via the sound output module 155 or headphones of an external electronic device (e.g., electronic device 102) that is directly (e.g., wired) or wirelessly connected to the electronic device 101.

[0049] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the environmental state outside electronic device 101 (e.g., user state), and then generate an electrical signal or data value corresponding to the detected state. According to examples, sensor module 176 may include, for example, a gesture sensor, a gyroscope sensor, an atmospheric pressure sensor, a magnetic sensor, an accelerometer, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0050] Interface 177 may support one or more specific protocols used to enable electronic device 101 to connect directly (e.g., wired) or wirelessly to external electronic devices (e.g., electronic device 102). Depending on the implementation, interface 177 may include, for example, a High Definition Multimedia Interface (HDMI), a Universal Serial Bus (USB) interface, a Secure Digital Card (SD) interface, or an audio interface.

[0051] Connection 178 may include a connector, via which electronic device 101 may be physically connected to an external electronic device (e.g., electronic device 102). According to examples, connection 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0052] The tactile module 179 can convert electrical signals into mechanical stimuli (e.g., vibration or motion) or electrical stimuli that can be recognized by a user through his touch or kinesthesia. According to embodiments, the tactile module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0053] Camera module 180 can capture still or moving images. Depending on the implementation, camera module 180 may include one or more lenses, an image sensor, an image signal processor, or a flash.

[0054] The power management module 188 manages the power supply to the electronic device 101. According to embodiments, the power management module 188 may be implemented as at least a portion of, for example, a power management integrated circuit (PMIC).

[0055] Battery 189 can power at least one component of electronic device 101. According to embodiments, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, or a fuel cell.

[0056] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to the example, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device 104 via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a local area network (LAN) or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components separate from each other (e.g., multiple chips). The wireless communication module 192 can identify or verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in a user identification module (not shown).

[0057] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (such as new radio (NR) access technologies). NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable low-latency communication (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 192 can support various technologies used to ensure performance in high-frequency bands, such as, for example, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. Wireless communication module 192 can support various requirements specified in electronic device 101, external electronic devices (e.g., electronic device 104), or network systems (e.g., second network 199). According to the implementation, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or greater) for implementing eMBB, lost coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane delay (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0058] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiator formed of conductive material or conductive patterns formed on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an antenna array). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190. Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, additional components besides the radiator (e.g., a radio frequency integrated circuit (RFIC)) may be further formed as part of antenna module 197.

[0059] According to an embodiment, antenna module 197 can form a millimeter-wave antenna module. According to an embodiment, the millimeter-wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and multiple antennas (e.g., an array antenna), wherein the RFIC is disposed on or adjacent to a first surface (e.g., a bottom surface) of the printed circuit board and is capable of supporting a specified high-frequency band (e.g., a millimeter-wave band), and the multiple antennas are disposed on or adjacent to a second surface (e.g., a top surface or a side surface) of the printed circuit board and are capable of transmitting or receiving signals in the specified high-frequency band.

[0060] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0061] According to the example, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. External electronic device 102 or external electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. According to the example, all or some operations that would be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic device 104, or server 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used. Electronic device 101 may use, for example, distributed computing or mobile edge computing to provide ultra-low latency services. In an embodiment, external electronic device 104 may include an Internet of Things (IoT) device. Server 108 may be an intelligent server using machine learning and / or neural networks. According to an example, external electronic device 104 or server 108 may be included in a second network 199. Electronic device 101 may be applied to intelligent services based on 5G communication technology or IoT-related technologies (e.g., smart homes, smart cities, smart cars, or healthcare).

[0062] External electronic devices 102, 104, or 108 may each be the same as or a different type of device than electronic device 101. According to embodiments, all or some operations to be performed at electronic device 101 may be performed at one or more of the external electronic devices 102, 104, or 108. For example, if electronic device 101 is required to automatically perform a function or service, or to perform a function or service in response to a request from a user or another device, instead of performing that function or service, electronic device 101 may request one or more external electronic devices to perform at least a portion of that function or service. The one or more external electronic devices receiving the request may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the performance to electronic device 101. Electronic device 101 may provide the result as at least part of a response to the request, with or without further processing of the result. For example, external electronic devices 102, 104, or 108 can render and transmit content data executed on the application to electronic device 101, and electronic device 101 receiving the data can output the content data to display module 160. If electronic device 101 detects user motion via, for example, an inertial measurement unit (IMU) sensor, processor 120 of electronic device 101 can correct the rendered data received from external electronic devices 102, 104, or 108 based on the motion information and output it to display module 160. Alternatively, electronic device 101 can transmit motion information to external electronic device 102 and request rendering, causing screen data to be updated accordingly. According to various embodiments, external electronic devices 102, 104, or 108 can be various types of devices, such as smartphones or housing devices capable of storing and charging electronic device 101.

[0063] Figure 2 This illustrates an electronic device 200 according to an embodiment of the present disclosure (e.g., Figure 1 A perspective view of the electronic device 101.

[0064] refer to Figure 2 The electronic device 200 may include a main body portion 210, a cover portion 220, a face contact portion 230, or a wearing portion 240. Although not shown, the electronic device 200 may include a display (e.g., Figure 1 The display module 160) or input device. The input device may be an external electronic device, such as a joystick (e.g., Figure 1 External electronic device 102). However, it is not limited to this and may include various types of input devices. Electronic device 200 can receive information input from the user through the input device.

[0065] The main body 210 may include, for example, a position adjustment unit 211 or an input unit 213. The position adjustment unit 211 may include, for example, a button, dial, or wheel. The position adjustment unit 211 can manually and / or automatically adjust the position of the lens provided in the main body 210, so that the user's eye is focused on the screen displayed on the monitor 160. The position adjustment unit 211 can, for example, adjust the distance between the monitor 160 and / or the lens provided in the main body 210 and the user's eye. The position adjustment unit 211 can, for example, be widened or narrowed by user manipulation, the distance between the monitor 160 and the lens, or the distance between the lens and the user's eye.

[0066] As an example, the position adjustment unit 211 may include a drive circuit capable of responding to a controller included in the main body portion 210 (e.g., Figure 1 The position of the lens is moved under the control of the processor 120. The drive circuit may include, for example, a motor driven by the control of the controller 120. The drive circuit may use the rotation direction and / or rotational force (or rotational speed) of the motor operated by the control of the controller 120 to move the lens forward (e.g., in the direction facing the electronic device 200, -y direction) or backward (e.g., in the direction opposite to the direction facing the electronic device 200, +y direction). The rotation direction of the motor may be used, for example, to determine the direction of lens movement (e.g., -y direction or +y direction). The rotational force of the motor may be used as energy, for example, to rotate a wheel included in the position adjustment unit 211. The lens whose position is adjusted by the position adjustment unit 211 may be at least one lens included in a lens group in which multiple lenses are arranged in a predetermined arrangement. The lens whose position is adjusted may be, for example, the lens in the lens group that is closest to the display 160. The lens whose position is adjusted may be, for example, the lens in the lens group that is farthest from the display 160. The lens whose position is adjusted may be, for example, a lens located in the middle of the lens group. The lens whose position is adjusted can be, for example, a combination of the lens in the lens group that is closest to the display 160 and the lens that is furthest from the display 160. The lens whose position is adjusted can be, for example, a combination of the lens that is closest to the display 160 and a lens located in the middle of the lens group. The lens whose position is adjusted can be, for example, a combination of the lens located in the middle of the lens group and a lens located furthest from the display 160.

[0067] The input unit 213 can be of various types, including, for example, a touchpad or a button. For example, a user can manipulate the input unit 213 to move the UI displayed on the display 160. A user can manipulate the input unit 213 to operate the camera module of the electronic device 200 (e.g., ...). Figure 1The camera module 180. A user can operate the camera module 180 to take photos or videos.

The first camera module 310 can be located at each of the four corners of the main body portion 210. The first camera module 310 can be a global shutter (GS) type camera. For example, the first camera module 310 can be a camera supporting 3DoF (degrees of freedom) or 6DoF, which can provide position recognition and / or motion recognition in 360-degree space (e.g., omnidirectional). The first camera module 310 can use multiple global shutter cameras with the same specifications and performance as stereo cameras to perform simultaneous localization and mapping (SLAM) functions and user movement recognition functions.

[0079] The second camera module 320 may include, for example, a first capturing camera 320a or a second capturing camera 320b. The second camera module 320 can capture external images. According to embodiments, the second camera module 320 may be a global shutter type or a rolling shutter (RS) type camera. For example, the second camera module 320 may include a high-resolution color camera and may be a high-resolution (HR) or photo-video (PV) camera. Furthermore, the second camera module 320 may provide autofocus (AF) and optical image stabilization (OIS) functions.

[0080] The depth sensor 330 may be disposed in the electronic device 200 adjacent to the second camera module 320. The depth sensor 330 may include a light emitting unit or a light receiving unit. For example, when the second camera module 320 acquires an external image, the light emitting unit may provide light to increase the brightness (e.g., illuminance) around the electronic device 200 and may reduce difficulties in image acquisition due to dark environments, mixing of various light sources, and / or light reflection. The depth sensor 330 may include, for example, an infrared (IR) camera (e.g., a time-of-flight (TOF) camera or a structured light camera). For example, an IR camera may serve as a sensor module for detecting the distance to an object (e.g., ...). Figure 1 At least a portion of the sensor module 176) is used to operate.

According to an embodiment, the third camera module 340 may capture the trajectory of a user's eye (e.g., pupil) or gaze. For example, the third camera module 340 may capture the reflected pattern of light emitted by a light-emitting unit toward the user's eye.

[0083] For example, the light emitting unit may use a third camera module 340 to emit infrared light to track gaze patterns. For example, the light emitting unit may include an IR LED. According to an implementation, the processor (e.g., Figure 1 The processor 120 can adjust the position of the virtual image so that the virtual image projected onto the display 160 corresponds to the direction of the user's pupil gaze. According to an embodiment, the third camera module 340 may include a global shutter (GS) type camera, and multiple third camera modules 340 with the same specifications and performance can be used to track the trajectory of the user's eyes or gaze.

[0084] The fourth camera module 350 may include a first face recognition camera 350a or a second face recognition camera 350b. The fourth camera module 350 can detect and track the user's facial expressions.

[0085] Electronic device 200 may include at least one optical module 360. Optical module 360 ​​may include, for example, a lens group consisting of one or more lenses, one or more lens housings, or a display (e.g., Figure 1 (Display module 160). One or more lenses can be fixed to the lens housing.

[0086] Includes a lens group in the optical module 360, a display 160, or a second camera module (e.g., Figure 4 The second camera module can be sequentially positioned in the -y direction relative to the user (e.g., the user's eye).

[0087] The optical module 360 ​​may include a first optical module (e.g., a left optical module) 360a or a second optical module (e.g., a right optical module) 360b. The display (e.g., Figure 1 The display module 160 or the transparent / semi-transparent lens can be integrally fixed or detachably fixed to the optical module 360.

[0088] According to the example, the optical module 360 ​​may include a lens barrel assembly (e.g., lens barrel assembly 400 of FIG. 5). Lens barrel assembly 400 may include at least one lens barrel (e.g., a first lens barrel 500 or a second lens barrel 600 of FIG. 5).

[0089] According to the example, the display 160 or the transparent / semi-transparent lens can be integrally or detachably fixed to the lens barrel assembly 400. Other components can also be mounted to at least one lens barrel 500, 600. As an example, an optical image stabilizer (OIS) module can be mounted to at least one lens barrel 500, 600. Ecomirror threads for transmitting power to at least one lens barrel 500, 600 can be installed as needed. Gear slots can be provided to at least one lens barrel 500, 600 as needed. In other words, Ecomirror threads or gear slots can be included in or omitted from at least one lens barrel 500, 600.

[0090] According to the example, at least one lens barrel 400, 500 can be manufactured by injection molding or die casting. During the manufacturing process of at least one lens barrel 400, 500, multiple dividing lines can be formed on the inner circumferential surface of at least one lens barrel 400, 500, and the dividing lines can be referred to as parting lines.

[0091] According to the example, the lens barrels 500 and 600 included in the lens barrel assembly 400 can rotate or move linearly. An inner lens barrel (e.g., the first lens barrel 500 of FIG. 5) can be fitted inside an outer lens barrel (e.g., the second lens barrel 600 of FIG. 5). The inner lens barrel 500 may be provided with a movable pin (e.g., movable pin 511 of FIG. 5) on its exterior to move while the outer lens barrel 600 is fixed. The outer lens barrel 500 may be provided with a cam profile (e.g., 611 of FIG. 5) formed to be etched and recessed within the outer lens barrel 500 to guide the movable pin 511 along a designated path. When the movable pin 511 moves on the cam profile 611, the inner lens barrel 500 can rotate or move linearly. Here, the movable pin 511 can be understood as a protrusion. The cam profile 611 can be understood as a guide groove. This is described in detail in FIG. 5.

[0092] The lens mounted to the optical module 360 ​​can be comprised of components included in the main body 210 (e.g., Figure 3 The controller in the main body 210) (e.g., Figure 1 The processor 120 moves. The drive circuit can move the position of the lens included in the optical module 360 ​​in response to the control of the controller 120. The drive circuit may include, for example, a motor driven by the control of the controller 120. The drive circuit can use the rotation direction and / or rotational force (or rotational speed) of the motor operated by the control of the controller 120 to move the lens forward (e.g., towards the display 160, -y direction) or backward (e.g., opposite to the display 160, +y direction). The rotation direction of the motor can be used, for example, to determine the direction of moving the lens (e.g., -y direction or +y direction). The rotational force of the motor can be used as energy, for example, to rotate a wheel included in the position adjustment unit 211. The lens whose position is adjusted by the position adjustment unit 211 may be at least one lens included in a lens group in which multiple lenses are arranged in a predetermined arrangement. The lens whose position is adjusted may be, for example, the lens in the lens group that is closest to the display 160. The lens whose position is adjusted may be, for example, the lens in the lens group that is farthest from the display 160. The lens whose position is adjusted may be, for example, a lens that is positioned in the middle of the lens group. The lens whose position is adjusted can be, for example, a combination of the lens in the lens group that is closest to the display 160 and the lens that is furthest from the display 160. The lens whose position is adjusted can be, for example, a combination of the lens that is closest to the display 160 and a lens located in the middle of the lens group. The lens whose position is adjusted can be, for example, a combination of the lens located in the middle of the lens group and a lens located furthest from the display 160.

Lens barrel assembly 400 can be applied to include a camera module (e.g., Figure 1 The electronic device 101 of the camera module 180 may include a lens barrel that can be applied to the camera module. For example, the electronic device 101 may include a smartphone, tablet PC, camera, wearable device, and is not limited thereto, and may include an electronic device that includes the camera module 180 to which the lens barrel can be applied. Figures 2 to 4 The head-mounted electronic device 101 shown can be understood as an example of an electronic device 101.

[0100] refer to Figure 6a and Figure 6b (a) shows a perspective view of the first lens barrel 500, and (b) shows the first movable pin 511 separated from the first lens barrel 500 when the first movable pin 511 of the first lens barrel 500 is provided as a separate component.

[0101] refer to Figures 7a to 7d (a) and (b) show perspective views illustrating the second lens barrel 600, and (c) shows a perspective view showing a portion of the second lens barrel 600 cut off. (d) is a perspective view illustrating an application example of the second lens barrel 600 according to an embodiment.

[0102] According to the example, the lens barrel assembly 400 may include a first lens barrel 500 and a second lens barrel 600. A display (e.g., Figure 1 The display module 160 or a transparent / semi-transparent lens can be integrally or detachably fixed to the lens barrel assembly 400. The lens barrel assembly 400 may further include a lens barrel as needed. As an example, a third lens barrel (not shown) may be provided inside the second lens barrel 600. In the following description, for ease of explanation, it is assumed that the lens barrel assembly 400 consists of a first lens barrel 500 and a second lens barrel 600, and the description will focus on the first lens barrel 500 and the second lens barrel 600.

[0103] According to the example, the first lens barrel 500 and the second lens barrel 600 can be injection molded using a mold device. The first lens barrel 500 and the second lens barrel 600 can be made of at least one or a combination of two or more of plastic, ceramic, or metal. Figure 12 The mold apparatus for manufacturing the second lens barrel 600 is described in detail in the following figures (e.g., Figure 12 (And the mold assembly 800 in the following figures).

[0104] According to the example, the first lens barrel 500 can rotate or move linearly within the second lens barrel 600 along the optical axis L. Here, the optical axis L can be defined as a virtual axis passing through the center of the lens provided in the lens barrel assembly 400. The optical axis L can partially or completely correspond to electronic devices (e.g., Figure 2 The direction (y direction) facing the electronic device 200.

[0105] According to the example, the first lens barrel 500 may be disposed inside the second lens barrel 600. At least a portion of the outer surface of the first lens barrel 500 may correspond to at least a portion of the inner surface of the second lens barrel 600.

[0106] According to the example, to enable the first lens barrel 500 to move within the second lens barrel 600, the first lens barrel 500 may include at least one movable pin 511, 513, 515. The at least one movable pin 511, 513, 515 can be understood as a conical or truncated conical protrusion projecting outward from a predetermined position in the first lens barrel 500. The at least one movable pin 511, 513, 515 may include a first movable pin 511, a second movable pin 513, and a third movable pin 515. The first to third movable pins 511, 513, 515 may be located at predetermined positions on the outer surface of the first lens barrel 500. The first to third movable pins 511, 513, 515 may be arranged at predetermined intervals on a cross-section perpendicular to the optical axis L in the first lens barrel 500. The predetermined interval may be, for example, 120°.

[0107] According to the example, the second lens barrel 600 may be provided with at least one cam profile 611, 613, 615, which is a path for moving the movable pins 511, 513, 515 provided on the first lens barrel 500. At least one cam profile 611, 613, 615 may be formed by engraving inside the second lens barrel 600. At least one cam profile 611, 613, 615 may be formed by pressing down a portion of the second lens barrel 600.

[0108] According to the example, at least one cam profile 611, 613, 615 may include a first cam profile 611, a second cam profile 613, and a third cam profile 615. The first to third cam profiles 611, 613, 615 may be set at predetermined intervals. The predetermined interval may be, for example, 120°.

[0109] According to the example, the first to third cam profiles 611, 613, and 615 can be provided in the same shape. The shapes of the first to third cam profiles 611, 613, and 615 can be composed of a combination of straight lines and curves. The shape of the cam profile is not limited to the shape shown, and can be provided in a variety of ways to correspond to the movement path of the lens barrel assembly 400.

[0110] In the enlarged view A of Figure 5, the first to third moving pins 511, 513, 515 and the first to third cam profiles 611, 613, 615 can correspond to each other. For example, the first moving pin 511 and the first cam profile 611 can correspond to each other. The second moving pin 513 and the second cam profile 613 can correspond to each other. The third moving pin 515 and the third cam profile 615 can correspond to each other.

[0111] According to the example, when the first lens barrel 500 moves inside the second lens barrel 600, the first movable pin 511 can move along a path formed in the first cam profile 611. When the first lens barrel 500 moves inside the second lens barrel 600, the second movable pin 513 can move along a path formed in the second cam profile 613. When the first lens barrel 500 moves inside the second lens barrel 600, the third movable pin 515 can move along a path formed in the third cam profile 615.

[0112] According to the example, the first to third movable pins 511, 513, and 515 can be integrally formed with the first lens barrel 500 or implemented as separate components. The first to third movable pins 511, 513, and 515 can have a conical or truncated conical shape. However, they are not limited thereto; the first to third movable pins 511, 513, and 515 can have a truncated pyramidal shape, wherein the cross-sectional area narrows as the height increases.

[0113] According to the example, when the first to third movable pins 511, 513, 515 are implemented as components separate from the first lens barrel 500, the first to third movable pins 511, 513, 515 may be detachable to facilitate separation from and / or connection with the first lens barrel 500.

[0114] In the enlarged view B of the first lens barrel 500 shown in FIG6(b), the first pin groove 531 can be provided at a predetermined position in the first lens barrel 500 for connecting the first movable pin 511. The connecting portion 521 of the first movable pin 511 can be disposed in the space provided in the first pin groove 531.

[0115] Referring to Figure 7(d), the second lens barrel 600 may further include a gear groove 670. The gear groove 670 may be provided inside the second lens barrel 600. The gear groove 670 may be formed by being engraved and recessed or embossed to protrude from the interior of the second lens barrel 600. The gear groove 670 may be formed by removing a portion of the second lens barrel 600. The gear groove 670 may be formed by providing a mold assembly for molding the second lens barrel 600 (e.g., Figure 12 The gear grooves 660 are molded by embossing protrusions on the mold assembly 800. Multiple gear grooves 670 may be provided in a direction parallel to the optical axis L of the second lens barrel 600. Gear grooves 660 may be formed at locations that do not intrude into or interfere with the path formed by the cam profiles (e.g., cam profiles 611, 613, 615 of FIG. 5) and / or vertical profiles (e.g., vertical profiles 621, 623, 625 of FIG. 5) provided on the second lens barrel 600.

[0116] According to the example, the gear groove 670 can be provided for gear meshing and power transmission within the second lens barrel 600. The inward extension angle of the gear groove 670 can form a predetermined angle. As the predetermined angle decreases, the supporting force for power transmission by the gear corresponding to the gear groove 670 can be enhanced.

[0117] As an example, the inward extension angle of the gear groove 670 can be between 20° and 30°. However, it is not limited to this; if undercutting does not occur when the second lens barrel 600 is molded by the mold device 800, the extension angle can be less than 20°.

[0118] Referring to Figure 7(d), the second lens barrel 600 may further include a threaded groove (not shown). The threaded groove may be provided inside the second lens barrel 600. The threaded groove may be formed by engraving and recessing inside the second lens barrel 600, or by removing a portion of the second lens barrel 600. The threaded groove may be formed by using a mold assembly (e.g., for molding the second lens barrel 600) to mold the second lens barrel 600. Figure 12 The embossed protrusion shape provided on the mold device 800 is molded. Multiple threaded grooves may be provided in a direction parallel to the optical axis L of the second lens barrel 600. The threaded grooves may be formed at locations that do not intrude into or interfere with the path formed by the cam profiles (e.g., cam profiles 611, 613, 615 of FIG. 5), gear grooves 670 and / or vertical profiles (e.g., vertical profiles 621, 623, 625 of FIG. 5) provided on the second lens barrel 600.

[0119] According to the example, the threaded groove can provide an Eckmi thread for engagement and power transmission within the second lens barrel 600. Since the thread angle of the trapezoidal Eckmi thread is approximately 29°, the inward extension angle of the threaded groove can form a predetermined angle. As the predetermined angle corresponds more closely to the thread angle of the Eckmi thread, the support force for power transmission to the gear corresponding to the threaded groove can be enhanced. As an example, the inward extension angle of the threaded groove can be between 20° and 30°.

[0120] Figure 8a and Figure 8b These are perspective and cross-sectional views showing a second lens barrel 600 (e.g., the second lens barrel 600 of FIG. 5) according to an embodiment of the present disclosure.

[0121] Figure 8a A perspective view showing the second lens barrel 600 is shown, and Figure 8b A cross section cut by the C-C' plane of (a) is shown.

[0122] According to the example, in addition to the first to third cam profiles 611, 613, and 615, the second lens barrel 600 may also include cam profiles 621, 623, and 625. Cam profiles 621, 623, and 625 can form an engraving path of predetermined length in a direction parallel to the optical axis L. In the following text, cam profiles 621, 623, and 625 are referred to as vertical profiles.

[0123] According to the example, vertical profiles 621, 623, 625 can be provided to receive individual lens barrels inside the second lens barrel 600. As an example, when the protrusions corresponding to the vertical profiles 621, 623, 625 are provided on the outside of the individual lens barrel, the individual lens barrel can perform linear movement along the optical axis inside the second lens barrel 600.

[0124] According to the example, vertical profiles 621, 623, and 625 may be provided to receive individual functional modules (e.g., optical image stabilization (OIS) modules) within the second lens barrel 600. As an example, the individual functional modules may be fixed within the second lens barrel 600 or perform linear motion within the second lens barrel 600.

[0125] According to the example, vertical profiles 621, 623, and 625 may include a first vertical profile 621, a second vertical profile 623, and a third vertical profile 625. The first to third vertical profiles 621, 623, and 625 may be set at predetermined intervals. The predetermined interval may be, for example, 120°.

[0126] According to the example, the first to third cam profiles 611, 613, and 615 can form paths independent of the first to third vertical profiles 621, 623, and 625. In other words, the first to third cam profiles 611, 613, and 615 can form distinct paths without interfering with or encroaching on the paths formed by the first to third vertical profiles 621, 623, and 625.

[0127] Figures 9a to 9c This is a cross-sectional view showing a second lens barrel 600 (e.g., the second lens barrel 600 of FIG5) according to an embodiment of the present disclosure.

[0128] refer to Figures 9a to 9c , Figure 9a A cross-section is shown, cut by a plane perpendicular to the optical axis (e.g., optical axis L in Figure 5) in the second lens barrel 600, and Figure 9b It shows Figure 9a Enlarged view of part (D). Figure 9c It shows Figure 9b A portion of the image is an enlarged view illustrating the second undercut phenomenon. Figures 9a to 9cThis can be understood as a conceptual illustration to describe the undercut phenomenon of internal extension angles 640° and 650° according to the cam profile (e.g., cam profiles 611, 613, 615 of Figure 5). Here, the undercut phenomenon can be understood as the undercutting phenomenon occurs as the injection-molded portion exits the mold assembly (e.g., Figure 12 The phenomenon of collision occurs when the mold assembly (800) separates from the following figures. Therefore, some differences may occur compared to the cross-sectional view shown in Figure 8.

[0129] According to the example, the first to third cam profiles 611, 613, and 615 can be cut by a plane perpendicular to the optical axis L.

[0130] According to the example, the first cam profile 611 can be implemented as cam profile 1-1 611a and cam profile 1-2 611b. The second cam profile 613 can be implemented as cam profile 2-1 613a and cam profile 2-2 613b. The third cam profile 615 can be implemented as cam profile 3-1 615a and cam profile 3-2 615b.

[0131] According to the example, cam profiles 1-1 611a, cam profile 2-1 613a, and cam profile 3-1 615a can be set at a distance of 120° from each other. Cam profiles 1-1 611a, cam profile 2-1 613a, and cam profile 3-1 615a can have the same shape.

[0132] According to the example, cam profiles 1-2 611b, cam profile 2-2 613b, and cam profile 3-2 615b can be set at a distance of 120° from each other. Cam profiles 1-2 611b, cam profile 2-2 613b, and cam profile 3-2 615b can have the same shape.

[0133] According to the example, the mold assembly 800 may include a plurality of sliding cores (e.g., Figure 12 The first to eighteenth sliding cores 810a to 810r). The lens barrel dividing angle α 630 used to divide the second lens barrel 600 can be determined corresponding to the number of sliding cores. The lens barrel dividing angle α 630 can be defined as α = 360 / N, where N can be defined as the number of sliding cores forming the mold device 800.

[0134] According to the example, the first to third cam profiles 611, 613, and 615 can be extended inward at a predetermined angle. The predetermined angle can be set by forming a pattern embossed on the die assembly 800. The predetermined angle is defined as the inward extension angle.

[0135] As an example, the internal extension angle γ of cam profile 1-1 611a can be defined as a first extension angle 65°, and the internal extension angle β of cam profile 1-2 611b can be defined as a second extension angle 64°. Here, it is assumed that α, β, and γ have the relationship α ≥ β > γ. In the following text, for ease of description, it is assumed that N = 6, α = 60°, β = 60°, and γ = 20°.

[0136] According to the example, the raw material (e.g., molten synthetic resin) for molding the second lens barrel 600 can be fed to the outside of the mold assembly 800, and the second lens barrel 600 can be separated as the mold assembly 800 contracts toward the center. In this case, the central direction in which the mold assembly 800 contracts to separate the second lens barrel 600 is defined as the first operating direction 710.

[0137] According to the example, based on the relationship between the extension angles 640 and 650 formed by the cam profile and the lens barrel dividing angle 630, undercutting may occur. In other words, as the mold device 800 retracts and the second lens barrel 600 separates from the mold device 800, a collision may occur between the second lens barrel 600 and the mold device 800.

[0138] According to the example, when the virtual line l3 that bisects the second extension angle 640 and the virtual line l1 that bisects the lens barrel division angle 630 are extended, the angle 633 formed by l3 and l1 is 30°, which is the same as the angle (β / 2) that bisects the second extension angle 640. Therefore, the right extension line 641 that forms the second extension angle 640 is parallel to the first operating direction 710. Since the right extension line 641 is parallel to the first operating direction 710, undercutting (i.e., collision between the mold device 800 and the second lens barrel 600) does not occur as the mold device 800 contracts.

[0139] According to the example, when the virtual line l2 that bisects the first extension angle 650 and the virtual line l1 that bisects the lens barrel division angle 630 are extended, the angle 631 formed by l2 and l1 is 30°, which is greater than the angle (γ / 2) that bisects the first extension angle 650. Therefore, the left extension line 651 that forms the first extension angle 650 is not parallel to the first operating direction 710. Since the left extension line 641 is not parallel to the first operating direction 710, an undercut phenomenon (i.e., a collision phenomenon between the mold device 800 and the second lens barrel 600) will occur as the mold device 800 contracts.

[0140] According to the example, when the cam profiles 611, 613, and 615 form a path parallel to the optical axis L, the probability of undercutting is high. In this case, undercutting can be avoided when the lens barrel grading angle 630 is at least less than or equal to the extension angles 640 and 650 formed by the cam profiles 611, 613, and 615.

[0141] Based on the example, the same content can be described for the second cam profile 613 and the third cam profile 615.

[0142] According to the example, as the elongation angles of the cam profiles 611, 613, and 615 narrow, the connection force between the second lens barrel 600 and the first lens barrel (e.g., the first lens barrel 500 in FIG. 5) can be strengthened. Therefore, it is beneficial to keep the lens barrel dividing angle 630 narrow to maintain the narrow elongation angles of the cam profiles 611, 613, and 615 while preventing undercutting. Therefore, the number of sliding cores constituting the mold assembly 800 can be increased to narrow the lens barrel dividing angle 630. The elongation angles of the cam profiles 611, 613, and 615 and the connection force between the first lens barrel 500 and the second lens barrel 600 are described in detail in FIG. 10.

[0143] Figure 10a and Figure 10b This is a cross-sectional view showing the connection force between a first lens barrel 500 (e.g., the first lens barrel 500 of FIG. 5) and a second lens barrel 600 (e.g., the second lens barrel 600 of FIG. 5) according to an extension angle of a cam profile (e.g., the first to third cam profiles 611, 613, 615 of FIG. 5). For ease of description, an enlarged cross-sectional view showing the vicinity of the first cam profile 611 and the first moving pin 511 is shown.

[0144] Refer to Figure 10, Figure 10a This is a cross-sectional view showing the connection force between the first lens barrel 500 and the second lens barrel 600 when the first cam profile 611 has a second extension angle 640 (e.g., the second extension angle 640 in Figure 9), and Figure 10b It is a cross-sectional view showing the connection force between the first lens barrel 500 and the second lens barrel 600 when the first cam profile 611 has a first extension angle 650 (e.g., the first extension angle 650 in FIG9).

[0145] According to the example, when an external force F acts on a lens assembly (e.g., lens assembly 400 in Figure 5), the external force F can be decomposed into two forces. As an example, the external force F can be decomposed into separate force components Fi. 11 F 21 and supporting force component F 12 F 22 In the separation force component F 11 F21 At this point, the first movable pin 511 attempts to separate from the outside of the first cam profile 611, under the support force component F. 12 F 22 At this point, the first moving pin 511 attempts to support the inside of the first cam profile 611.

[0146] Based on the example, the force components decomposed from an external force F (e.g., the separating force F) 11 F 21 and supporting force F 12 F 22 The value can vary depending on the magnitude of the extension angles 640° and 650° of the first cam profile 611. As an example, in (a), the first separating force F decomposed from the external force F... 11 The component can be smaller than the second separating force F decomposed from the external force F in (b). 21 Components. As an example, in (a), the first support force F is decomposed from the external force F. 12 The component can be greater than the second support force F decomposed from the external force F in (b). 22 Therefore, in the case (b) where the extension angles 640 and 650 of the first cam profile 611 are smaller, the lens barrel assembly 400 can more robustly resist external impacts (e.g., external force F).

[0147] According to the example, by reducing the angles of the cam profiles 611, 613, 615 according to this disclosure to 20°, a lens barrel assembly 400 with enhanced rigidity between the first lens barrel 500 and the second lens barrel 600 will be provided.

[0148] Figure 11a and Figure 11b This is a perspective view showing a cutting line 660 applied to the inner peripheral surface of a second lens barrel 600 (e.g., the second lens barrel 600 of FIG. 5) according to an embodiment of the present disclosure.

[0149] Refer to Figure 11, Figure 11a This is a perspective view showing the cutting line 660 applied to the second lens barrel 600, and Figure 11b It shows the unfolding from the inner circumferential surface. Figure 11a The front view of the second lens barrel 600 shown in the figure.

[0150] According to the example, when the second lens barrel 600 is made by a mold device (e.g., Figure 12 During the manufacture of the mold assembly 800, multiple cutting lines 660 can be provided inside the second lens barrel 600. The cutting lines 660 can be referred to as parting lines. The parting lines 660 can be due to the sliding core constituting the mold assembly 800 (e.g., Figure 12The parting line 660 is created by the gap or step between the first to eighteenth sliding cores 810a to 810r. Multiple parting lines 660 can be provided. For example, the parting line 660 can be composed of 18 parting lines 660a to 660r, and is not limited thereto, and the parting line 660 can be composed of 18 or more.

[0151] According to the example, the parting line can be implemented as a diagonal line. In other words, the parting line may not be parallel to the optical axis L. The parting line can form a predetermined angle with the optical axis L. The predetermined angle can be, for example, greater than 0° and less than 45°.

[0152] According to the example, the parting line can be implemented vertically. The parting line can be implemented vertically corresponding to the dividing shape structure of the mold assembly 800. When the parting line is implemented vertically, it can be parallel to the optical axis L. To implement the parting line vertically, in the sliding core (e.g., Figure 12 The angle formed between the side surfaces of adjacent sliding cores included in the first to eighteenth sliding cores (810a to 810r) can substantially satisfy 0°.

[0153] According to the example, the parting line can be implemented as a curved line. The parting line can be implemented as a line that is bent at least multiple times, corresponding to the dividing shape structure of the mold device 800.

[0154] As shown in the example, the parting line can be implemented as a curve. The parting line can be implemented as a curve corresponding to the dividing shape structure of the mold device 800.

[0155] According to the example, the parting line 660 can extend to the inner circumferential surface of the second lens barrel 600. The parting line 660 can extend from a first opening surface 601 provided on two opposite sides to a second opening surface 603. The inner circumference of the first opening surface 601 can be defined as a first circumference. The inner circumference of the second opening surface 603 can be defined as a second circumference. The lengths of the first circumference and the second circumference can be the same or different.

[0156] According to the example, the first circumference can be divided into multiple circumferences by the parting line 660. The arc into which the first circumference is divided by the parting line 660 can be defined as the first arc.

[0157] According to the example, the second circumference can be divided into multiple circumferences by the parting line 660. The arc into which the second circumference is divided by the parting line 660 can be defined as the second arc.

[0158] According to the example, the fractal line 660 may include the first to the eighteenth fractal lines 660a, 660b, 660c, 660d, 660e, 660f, 660g, 660h, 660i, 660j, 660k, 660l, 660m, 660n, 660o, 660p, 660q, and 660r.

[0159] According to the example, among the multiple first arcs divided by multiple parting lines 660a to 660r at the first opening surface 601, the lengths of two adjacent first arcs can be different. In other words, within a first arc, the lengths of any two adjacent parting lines can be different.

[0160] As an example, among a plurality of first arcs, the length of the first arc divided by the first fractal line 660a and the second fractal line 660b may be different from the length of the first arc divided by the second fractal line 660b and the third fractal line 660c.

[0161] As an example, among multiple first arcs, the length of the first arc divided by the second fractal line 660b and the third fractal line 660c can be different from the length of the first arc divided by the third fractal line 660c and the fourth fractal line 660d. Similarly, the length of the first arc divided by two adjacent fractals among multiple fractals 660a to 660r can be different.

[0162] According to the example, in the plurality of second arcs divided by multiple parting lines 660a to 660r at the second opening surface 603, the lengths of two adjacent second arcs can be different. In other words, within the second arc, the lengths of any two adjacent parting lines can be different.

[0163] As an example, among a plurality of second arcs, the length of the second arc divided by the first fractal line 660a and the second fractal line 660b may be different from the length of the second arc divided by the second fractal line 660b and the third fractal line 660c.

[0164] As an example, among multiple second arcs, the length of the second arc divided by the second fractal line 660b and the third fractal line 660c can be different from the length of the second arc divided by the third fractal line 660c and the fourth fractal line 660d. Similarly, the length of the second arc divided by two adjacent fractals among multiple fractals 660a to 660r can be different.

[0165] According to the example, the length of the first target arc, which is divided by two adjacent parting lines among a plurality of parting lines 660a to 660r, of the first circumference may be different from the length of the second target arc, which is divided by the two adjacent parting lines of the second circumference.

[0166] As an example, the length of the first target arc, into which the first circumference is divided by the first fractal line 660a and the second fractal line 660b, may be different from the length of the second target arc, into which the second circumference is divided by the first fractal line 660a and the second fractal line 660b.

[0167] As an example, the length of the first target arc, which is divided by the second fractal line 660b and the third fractal line 660c, may be different from the length of the second target arc, which is divided by the second fractal line 660b and the third fractal line 660c. Similarly, the lengths of the first target arc and the second target arc, which are divided by any two adjacent fractal lines 660a to 660r, may be different.

[0168] According to the example, the parting lines 660 can be formed in a number equal to the number of sliding cores constituting the mold assembly 800. As an example, if the number of sliding cores is 18, then 18 parting lines 660 can be formed in the second lens barrel 600. In the following text, it is assumed that the number of sliding cores and the number of parting lines 660 are 18.

[0169] According to the example, in the unfolded diagram of (b), the spacing between two adjacent parting lines included in parting line 660 can widen or narrow as the height h of the second lens barrel 600 increases. In other words, the spacing between two adjacent parting lines can vary depending on the height h.

[0170] As an example, the spacing between the first parting line 660a and the second parting line 660b included in the parting line 660 can narrow as the height h increases. In other words, the spacing 1-2w 12 Comparison interval 1-1 w 11 narrow.

[0171] As an example, the spacing between the second parting line 660b and the third parting line 660c included in parting line 660 can widen as the height h increases. In other words, the spacing 2-2w 22 Comparison interval 2-1 w 21 Width.

[0172] According to the example, in the unfolded diagram of (b), each of the odd-numbered fractals included in fractal line 660 (e.g., the first fractal line 660a, the third fractal line 660c, ..., the seventeenth fractal line 660q) can be parallel to each other. Each of the even-numbered fractals included in fractal line 660 (e.g., the second fractal line 660b, the fourth fractal line 660d, ..., the eighteenth fractal line 660r) can be parallel to each other.

[0173] According to the example, in the unfolded diagram of (b), two adjacent parting lines including the first to eighteenth parting lines 660a to 660r may not be parallel to each other. This can occur because two adjacent sliding cores constituting the mold assembly 800 are not aligned with each other. In other words, this can occur because the operating speeds of the two adjacent sliding cores are different. This is in Figure 22 Detailed description is provided.

[0174] Figure 12 This is a perspective view showing a mold apparatus 800 according to an embodiment of the present disclosure.

[0175] Figure 13 This is a perspective view showing a mold apparatus 800 according to an embodiment of the present disclosure. Figure 13 It shows from Figure 12 The mold assembly 800 shown removes some sliding cores (e.g., the first to fourth sliding cores 810a, 810b, 810c, 810d).

[0176] Figure 14 This is a top view showing a mold apparatus 800 according to an embodiment of the present disclosure. Figure 14 The image shown is viewed in the E-E' direction. Figure 12 The mold device 800 shown.

[0177] refer to Figures 12 to 14 The diagram shows a first operating state in which the center core 820 has been moved to the uppermost position in the vertical direction relative to the mold assembly 800 to mold the second lens barrel (e.g., the second lens barrel 600 in FIG5).

[0178] According to the example, the mold assembly 800 may include a plurality of sliding cores 810a to 810r or a center core 820. The plurality of sliding cores 810a to 810r may include first to eighteenth sliding cores 810a to 810r.

[0179] According to the example, in order for the mold assembly 800 to mold the second lens barrel 600, the center core 820 can operate in the vertical direction. The direction in which the center core 820 operates can be referred to as the second operating direction 720. The second operating direction 720 can correspond to the optical axis direction (e.g., the optical axis L in Figure 5).

[0180] According to the example, in order for the mold assembly 800 to mold the second mirror barrel 600, in response to the operation of the central core 820 in the second operating direction 720, a plurality of sliding cores 810a to 810r can retract toward the center of the central core 820 or extend in the opposite direction. The direction in which the plurality of sliding cores 810a to 810r retract or extend can be referred to as the first operating direction 710.

[0181] As illustrated in the example, when multiple sliding cores 810a to 810r contract or extend, some of the sliding cores can operate at different speeds than each other. Therefore, interference between the sliding cores can be minimized in response to the operation of the multiple sliding cores 810a to 810r.

[0182] As an example, the operating speed of odd-numbered sliding cores (e.g., the first sliding core 810a, the third sliding core 810c, ... the seventeenth sliding core 810q) among a plurality of sliding cores 810a to 810r can be faster than that of even-numbered sliding cores (e.g., the second sliding core 810b, the fourth sliding core 810d, ... the eighteenth sliding core 810r). In other words, during the same operating time, the distance that odd-numbered sliding cores contract or extend can be greater than the distance that even-numbered sliding cores contract or extend. Figure 15 The relevant operations are described in detail in the accompanying diagrams.

[0183] According to an example, the mold assembly 800 may include a molding portion 815. The molding portion 815 may provide for molding an injection-molded product within the mold assembly 800. The molding portion 815 may be formed as a predetermined outer peripheral surface provided by a plurality of sliding cores 810a to 810r. The molding portion 815 may be filled with injection molding material to mold a second lens barrel 600. In the molding portion 815, a step difference may exist between adjacent sliding cores included in the plurality of sliding cores 810a to 810r. Thus, parting lines (e.g., parting lines 660a to 660r of FIG. 11) may be formed inside the second lens barrel 600 in response to the mold assembly 800 molding the second lens barrel 600.

[0184] According to the example, the molded portion 815 may have embossing paths formed corresponding to cam profiles (e.g., cam profiles 611, 613, 615 or vertical profiles 621, 623, 625 in FIG. 5) formed inside the second lens barrel 600. Due to the embossing paths, cam profiles 611, 613, 615 or vertical profiles 621, 623, 625 may be formed inside the second lens barrel 600 when the mold assembly 800 molds the second lens barrel 600.

[0185] According to the example, molding material can be filled to a predetermined thickness along the outer peripheral surface of the molding portion 815. The mold assembly 800 can mold the second lens barrel 600 according to the operation of a plurality of sliding cores 810a to 810r and a central core 820.

[0186] According to the example, a plurality of sliding cores 810a to 810r may have sliding members 811a to 811r for sliding of the central core 820. The sliding members 811a to 811r may be provided with wedge-shaped protrusions 813a to 813r for sliding of the central core 820 in a second operating direction 720. Wedge-shaped grooves 830a to 830r provided in the central core 820 may contact along the wedge-shaped protrusions 813a to 813r, and the central core 820 may operate in the second operating direction 720.

[0187] According to the example, the first sliding member 811a of the first sliding core 810a may include a wedge-shaped protrusion 813a, a first sliding surface 814a (e.g., the first sliding surface 814a of FIG. 19), a second sliding surface 815a (e.g., the first sliding surface 815a of FIG. 19), a first side surface 816a (e.g., the first side surface 816a of FIG. 19), and a second side surface 817a (e.g., the second side surface 817a of FIG. 19). The first wedge-shaped protrusion 813a may correspond to a first wedge-shaped groove 830a (e.g., the first wedge groove 830a of FIG. 19) provided in the first protrusion 821a (e.g., the first protrusion 821a of FIG. 19) of the central core 820. The first sliding surface 814a may correspond to a first sliding surface 831a (e.g., the first sliding surface 831a of FIG. 19) provided in the first protrusion 821a of the central core 820. The second sliding surface 815a may correspond to the second sliding surface 833a provided in the first protrusion 821a of the central core 820 (e.g., the second sliding surface 833a of FIG. 19).

[0188] According to the example, the second sliding member 811b of the second sliding core 810b may include a wedge-shaped protrusion 813b, a first sliding surface 814b (e.g., the first sliding surface 814b of FIG. 19), a second sliding surface 815b (e.g., the first sliding surface 815b of FIG. 19), a first side surface 816b (e.g., the first side surface 816b of FIG. 19), and a second side surface 817b (e.g., the second side surface 817b of FIG. 19). The first wedge-shaped protrusion 813b may correspond to a first wedge-shaped groove 830b (e.g., the first wedge-shaped groove 830b of FIG. 19) provided in the first recess 821b (e.g., the first recess 821b of FIG. 19) of the central core 820. The first sliding surface 814b may correspond to a first sliding surface 831b (e.g., the first sliding surface 831b of FIG. 19) provided in the first recess 821b of the central core 820. The second sliding surface 815b may correspond to the second sliding surface 833b provided in the first recess 821b of the central core 820 (e.g., the second sliding surface 833b of FIG. 19). The first side surface 816b may correspond to the first side surface 832b provided in the first recess 821b of the central core 820 (e.g., the first side surface 832b of FIG. 19). The second side surface 817b may correspond to the second side surface 834b provided in the first recess 821b of the central core 820 (e.g., the second side surface 834b of FIG. 19).

[0189] Figure 15 This is a perspective view showing a mold apparatus 800 according to an embodiment of the present disclosure.

[0190] Figure 16This is a perspective view showing a mold apparatus 800 according to an embodiment of the present disclosure. Figure 16 It shows from Figure 15 The mold assembly 800 shown removes some sliding cores (e.g., the first to fourth sliding cores 810a, 810b, 810c, 810d).

[0191] Figure 17 This is a top view showing a mold apparatus 800 according to an embodiment of the present disclosure.

[0192] refer to Figures 15 to 17 The diagram illustrates a second operating state in which, in order for the mold assembly 800 to mold the second lens barrel (e.g., the second lens barrel 600 in Figure 5), the central core 820 is moved a predetermined distance in the second operating direction 720. In the following text, since all or part of the correspondence... Figures 12 to 14 Therefore, the main focus is on describing the differences.

[0193] According to the example, as the central core 820 moves a predetermined distance in the second operating direction 720, some of the sliding cores, including the plurality of sliding cores 810a to 810r, can operate at different speeds than each other. Therefore, interference between the sliding cores can be minimized in response to the operation of the plurality of sliding cores 810a to 810r.

[0194] As an example, the operating speed of odd-numbered sliding cores (e.g., the first sliding core 810a, the third sliding core 810c, ... the seventeenth sliding core 810q) among a plurality of sliding cores 810a to 810r can be faster than that of even-numbered sliding cores (e.g., the second sliding core 810b, the fourth sliding core 810d, ... the eighteenth sliding core 810r). In other words, during the same operating time, the distance that odd-numbered sliding cores contract or extend can be greater than the distance that even-numbered sliding cores contract or extend. Figure 22 The moving speeds of multiple sliding cores 810a to 810r are described in detail.

[0195] According to the example, a structure can be proposed that allows the central core 820 to operate in a second operating direction 720 while minimizing interference between the plurality of sliding cores 810a to 810r. Each of the plurality of sliding cores 810a to 810r may be provided with a sliding portion 811a to 811r, and wedge-shaped grooves 830a to 830r corresponding to the sliding portions 811a to 811r may be provided on the outer surface of the central core 820. The central core 820 corresponding to the sliding portions 811a to 811r can slide in the second operating direction 720, and the plurality of sliding cores 810a to 810r can contract in a first operating direction 710, or the central core 820 corresponding to the sliding portions 811a to 811r can slide in a direction opposite to the second operating direction 720, and the plurality of sliding cores 810a to 810r can extend in a direction opposite to the first operating direction 710. The structure of the wedge-shaped grooves 830a to 830r... Figure 18 As detailed in the accompanying figures.

[0196] Figure 18 This is a perspective view showing the central core 820 according to an embodiment of the present disclosure.

[0197] Figures 19a to 19c The views shown are, according to embodiments of the present disclosure, a cross-sectional view of a central core 820 cut at a predetermined height from above, and a partial perspective view showing a first sliding core 810a and a second sliding core 810b.

[0198] Figure 20 This is a cross-sectional view showing the central core 820 according to an embodiment of the present disclosure.

[0199] refer to Figures 18 to 20 The center core 820 is disposed inside the mold device 800 and can move in the second operating direction 720. When the center core 820 moves in the second operating direction 720 or in a direction opposite to the second operating direction 720, the plurality of sliding cores 810a to 810r can retract or extend.

[0200] According to the example, some of the multiple sliding cores 810a to 810r can move a larger distance during the same period of time. Therefore, the angles formed between two adjacent sliding cores 810a to 810r and the center core 820 can be different from each other. This is in Figure 22 Detailed description is provided.

[0201] According to the example, the central core 820 may have alternating protrusions and recesses on its outer peripheral surface corresponding to the second operating direction 720. The protrusions of the central core 820 may be referred to as protrusions 821a, 821c, ..., 821q. The recesses of the central core 820 may be referred to as recesses 821b, 821d, ..., 821r. The recesses 821b, 821d, ..., 821r and the protrusions 821a, 821c, ..., 821q may have a plurality of wedge-shaped grooves 830a to 830r. The plurality of wedge-shaped grooves 830a to 830r may include first to eighteenth wedge-shaped grooves 830a to 830r. Odd-numbered wedge grooves (e.g., first wedge groove 830a, third wedge groove 830c, ..., seventeenth wedge groove 830q) included in a plurality of wedge grooves 830a to 830r can be provided in corresponding protrusions 821a, 821c, ..., 821q. Even-numbered wedge grooves (e.g., second wedge groove 830b, fourth wedge groove 830d, ..., eighteenth wedge groove 830r) included in a plurality of wedge grooves 8301a to 830r can be provided in corresponding recesses 821b, 821d, ..., 821r. The plurality of wedge grooves 830a to 830r can have shapes corresponding to the shapes of the plurality of wedge protrusions 813a to 813r included in a plurality of sliding cores 810a to 810r. The wedge protrusions 813a to 813r can contact the plurality of wedge grooves 830a to 830r.

[0202] Although not shown, the central core 820 may have multiple wedge-shaped protrusions (not shown), and the multiple sliding cores 810a to 810r may have multiple wedge-shaped grooves (not shown). The shapes of the multiple sliding portions provided in the central core 820 and the shapes of the wedge-shaped grooves provided in the multiple sliding cores 810a to 810r may correspond to each other.

[0203] According to the example, the first wedge groove 830a and the first wedge protrusion 813a can correspond to each other. The second wedge groove 830b and the second wedge protrusion 813b can correspond to each other. The third wedge groove 830c and the third wedge protrusion 813c can correspond to each other. The fourth wedge groove 830d and the fourth wedge protrusion 813d can correspond to each other. The fifth wedge groove 830e and the fifth wedge protrusion 813e can correspond to each other. The sixth wedge groove 830f and the sixth wedge protrusion 813f can correspond to each other. The seventh wedge groove 830g and the seventh wedge protrusion 813g can correspond to each other. The eighth wedge groove 830h and the eighth wedge protrusion 813h can correspond to each other. The ninth wedge groove 830i and the ninth wedge protrusion 813i can correspond to each other. The tenth wedge groove 830j and the tenth wedge protrusion 813j can correspond to each other. The eleventh wedge groove 830k and the eleventh wedge protrusion 813k can correspond to each other. The twelfth wedge groove 830l and the twelfth wedge protrusion 813l can correspond to each other. The thirteenth wedge groove 830m and the thirteenth wedge protrusion 813m can correspond to each other. The fourteenth wedge groove 830n and the fourteenth wedge protrusion 813n can correspond to each other. The fifteenth wedge groove 830o and the fifteenth wedge protrusion 813o can correspond to each other. The sixteenth wedge groove 830p and the sixteenth wedge protrusion 813p can correspond to each other. The seventeenth wedge groove 830q and the seventeenth wedge protrusion 813q can correspond to each other. The eighteenth wedge groove 830r and the eighteenth wedge protrusion 813r can correspond to each other.

[0204] For ease of explanation, the description will focus on the first wedge groove 830a and the second wedge groove 830b among the plurality of wedge grooves 830a to 830r. Odd-numbered wedge grooves included in the plurality of wedge grooves 830a to 830r (e.g., the third wedge groove 830c, the fifth wedge groove 830e, ..., the seventeenth wedge groove 830q) may correspond to the first wedge groove 830a. Even-numbered wedge grooves included in the plurality of wedge grooves 830a to 830r (e.g., the fourth wedge groove 830d, the sixth wedge groove 830f, ..., the eighteenth wedge groove 830r) may correspond to the second wedge groove 830b. Therefore, in addition to the first wedge groove 830a, the description of the first wedge groove 830a can also be applied to odd-numbered wedge grooves 830c, 830e, ..., 830q, and in addition to the second wedge groove 830b, the description of the second wedge groove 830b can also be applied to even-numbered wedge grooves 830d, 830f, ..., 830r.

[0205] According to the example, on the surfaces where the first wedge groove 830a and the first wedge protrusion 813a slide (e.g., Figure 22 The angle formed between the sliding surface 819e and the central axis (e.g., optical axis L) of the central core 820 can be defined as the first operating angle (e.g., Figure 22The first operating angle θ1). On the surface where the second wedge groove 830b and the second wedge protrusion 813b slide (e.g., Figure 22 The angle formed between the sliding surface 819n and the central axis (e.g., optical axis L) of the central core 820 can be defined as the second operating angle (e.g., Figure 22 The second operating angle θ2). The first operating angle θ1 and the second operating angle θ2 can be substantially different. Therefore, when the center core 820 moves in the second operating direction 720, the inner sliding core corresponding to the first operating angle θ1, which has a relatively large angle, can move a greater distance than the inner sliding core corresponding to the second operating angle θ2. As an example, the sliding core corresponding to the first operating angle θ1 (e.g., the first sliding core 810a) can move a greater distance than the sliding core corresponding to the second operating angle θ2 (e.g., the second sliding core 810b). This is in Figure 22 Detailed description is provided.

[0206] According to the example, the operating core 820 can contact a plurality of sliding cores 810a to 810r and slide in the second operating direction 720. As an example, the first wedge groove 830a can slide along the first wedge protrusion 813a. The second wedge groove 830b can slide along the second wedge protrusion 813b.

[0207] According to the example, the first protrusion 821a may project outward compared to the first recess 821b. The first protrusion 821a may include a first wedge groove 830a, a first sliding surface 831a, and a second sliding surface 833a. The first wedge groove 830a may correspond to the first wedge protrusion 813a. The first sliding surface 831a may be defined as a surface positioned on the left side of the first wedge groove 830a, and the second sliding surface 833a may be defined as a surface positioned on the right side of the first wedge groove 830a. The first wedge protrusion 813a may be guided by the first wedge groove 830a provided in the first protrusion 821a and slide along the first sliding surface 831a and the second sliding surface 833a.

[0208] According to an example, the first recess 821b may include a second wedge groove 830b, a first sliding surface 831b, a second sliding surface 833b, a first side surface 832b, and a second side surface 834b. The first sliding surface 831b may be defined as a surface positioned on the left side of the second wedge groove 830b, and the second sliding surface 833b may be defined as a surface positioned on the right side of the second wedge groove 830b. A second wedge protrusion 813b may be guided by the second wedge groove 830b provided in the first recess 821b and slide along the first sliding surface 831b and the second sliding surface 833b. The first side surface 832b may be defined as a side surface positioned on the left side of the first sliding surface 831b. The second side surface 834b may be defined as a side surface positioned on the right side of the second sliding surface 833b.

[0209] According to the example, when the central core 820 moves relative to the plurality of sliding cores 810a to 810r in the second operating direction 720, the wedge protrusion 813a and the first wedge groove 830a of the first sliding core 810a can correspond to each other.

[0210] refer to Figure 19b and Figure 19c The first wedge groove 830a and the first wedge protrusion 813a can correspond to each other. When the central core 820 moves in the second operating direction 720, the first wedge protrusion 813a can be guided by the first wedge groove 830a, and the first sliding surface 814a can slide while contacting the first sliding surface 831a of the first protrusion 821a. When the central core 820 moves in the second operating direction 720, the first wedge protrusion 813a can be guided by the first wedge groove 830a, and the second sliding surface 815a can slide while contacting the second sliding surface 833a of the first protrusion 821a.

[0211] According to the example, due to the angle formed by the first sliding surfaces 831a, 831c, 831e, ..., 831q of the protrusions 821a, 821c, 821e, ..., 821q and the second sliding surfaces 833a, 833c, 833e, ..., 833q of the protrusions 821a, 821c, 821e, ..., 821q and the corresponding first sliding surfaces 814a, 814c, ..., 814q and second sliding surfaces 815a, 815c, ..., 815q of the odd sliding cores 810a, 810c, ..., 810q relative to the height direction (e.g., the optical axis L direction) of the central core 820, the odd sliding cores 810a, 810c, ..., 810q can move a predetermined distance toward the center direction (e.g., the first operating direction 710) of the central core 820. Due to the angle formed by the first sliding surfaces 831b, 831d, ..., 831r and the second sliding surfaces 833b, 833d, ..., 833r of the recesses 821b, 821d, ..., 821r, and the corresponding first sliding surfaces 814b, 814d, 814f, ..., 814r and second sliding surfaces 815b, 815d, 815f, ..., 815r of the even-numbered sliding cores 810b, 810d, ..., 810r relative to the height direction (e.g., the optical axis L direction) of the central core 820, the even-numbered sliding cores 810b, 810d, ..., 810r can move a predetermined distance toward the center direction (e.g., the first operating direction 710) of the central core 820.

[0212] According to the example, because the angles (e.g., the first operating angle θ1) formed between the protrusions 821a, 821c, 821e, ..., 821q and the first sliding surfaces 814a, 814c, ..., 814q to the second sliding surfaces 815a, 815c, ..., 815q of the odd-numbered sliding cores 810a, 810c, ..., 810q are greater than the angles (e.g., the first operating angle θ1) formed between the recesses 821b, 821d, ..., 821r and the even-numbered sliding cores 810b, 810d, ... The angle (e.g., a second operating angle θ2) formed between the first sliding surfaces 814b, 814d, 814f, ... 814r of 810r and the second sliding surfaces 815b, 815d, 815f, ... 815r allows the odd-numbered sliding cores 810a, 810c, ..., 810q to move a greater distance in the central direction (e.g., the first operating direction 710) of the central core 820 than the even-numbered sliding cores 810b, 810d, ..., 810r. According to the example, when the central core 820 moves relative to the plurality of sliding cores 810a to 810r in the second operating direction 720, the second wedge-shaped protrusion 813b and the second wedge-shaped groove 830b of the second sliding core 810b can correspond to each other.

[0213] refer to Figure 19b and Figure 19cThe second wedge-shaped groove 830b and the second wedge-shaped protrusion 813b of the first recess 821b can correspond to each other. When the central core 820 moves in the second operating direction 720, the first sliding surface 814b of the second sliding core 810b can slide while contacting the first sliding surface 831b of the first recess 821b. When the central core 820 moves in the second operating direction 720, the second sliding surface 815b of the second sliding core 810b can slide while contacting the second sliding surface 833b of the first recess 821b. When the central core 820 moves in the second operating direction 720, the first side surface 816b of the second sliding core 810b can slide while contacting the first side surface 832b of the first recess 821b, and the second side surface 817b of the first sliding core 810a can slide while contacting the second side surface 834a of the first recess 821b.

[0214] According to the example, when the center core 820 moves a predetermined distance in the second operating direction 720 (e.g., Figure 22 When the moving distance d is reached, it is guided by wedge-shaped grooves 830a to 830r and wedge-shaped protrusions 813a to 813r inclined at a first operating angle θ1 or a second operating angle θ2, and the central core 820 can be operated a predetermined distance (e.g., ) in the first operating direction 710 while sliding on the sliding surface in the sliding cores 810a to 810r. Figure 22 (l1, l2).

[0215] According to the example, the first side surface 832b or the second side surface 834b of the first recess 821b can be inclined at a predetermined angle to the first sliding surface 831b or the second sliding surface 833b, respectively. With the presence of the first side surface 832b or the second side surface 834b, multiple separate sliding cores (e.g., Figure 12 The number of the first to eighteenth sliding cores (810a to 810r) can be expanded to 18.

[0216] As an example, due to the presence of a first side surface 832b and a second side surface 834b forming a predetermined angle with the lower surface, the first sliding surface 831b and the second sliding surface 833b of the second wedge groove 821b can extend the length of the central core 820 in the second operating direction 720. Therefore, the second wedge groove 821b can slide in the second operating direction 720 corresponding to the sliding surfaces 831b and 833b.

[0217] As an example, when the first side surface 832b or the second side surface 834b is absent, the first sliding surface 831b and the second sliding surface 833b provided in the first recess 821b of the central core 820 can contact each other as they extend in the second operating direction 720. Thus, the first sliding surface 814b and the second sliding surface 815b of the second sliding core 810b do not need to extend the length of the central core 820 in the second operating direction 720.

[0218] Figure 21a and Figure 21b A cross-section of a mold apparatus 800 viewed from the front, according to an embodiment of the present disclosure, is shown.

[0219] refer to Figure 21a and Figure 21b , Figure 21a The first operating state is shown (e.g., Figures 12 to 14 (first operating state), and Figure 21b The second operating state is shown (e.g., Figures 15 to 17 The second operating state). In other words, Figure 21a It shows along Figure 12 The sectional view taken by line F-F' in the middle, and Figure 21b It shows along Figure 15 The sectional view taken by line H-H' in the middle.

[0220] According to the example, in addition to the sliding core 810 (e.g., Figure 12 Multiple sliding cores 810a to 810r) and center core 820 (e.g., Figure 12 In addition to the central core 820, the mold assembly 800 may also include a stripper block 840 and a back plate 850. Besides what is shown, the mold assembly 800 may also include an outer molded portion and an outer sliding core (not shown) for fixing the second lens barrel 600 or for engraving a predetermined pattern in the outer peripheral surface of the second lens barrel 600.

[0221] According to the example, the stripper block 840 may be disposed on the outer surface of the sliding core 810. The stripper block 840 can be understood as a component provided to fix the mold portion or restrict the movement of the mold portion. In other words, the stripper block 840 can prevent the sliding core 810 from moving in the +z axis direction (e.g., the +z axis direction of FIG. 21) in response to the movement of the center core 820 in the second operating direction 720 or in the direction opposite to the second operating direction 720.

[0222] According to the example, the back plate 850 can be implemented as an annular plate with a predetermined thickness. The back plate 850 can be positioned on the lower surface of the stripper block 840. The back plate 850 can prevent the sliding core 810 from moving in the -z-axis direction (e.g., the -z-axis direction of FIG. 21) in response to the movement of the center core 820 in the second operating direction 720 or in a direction opposite to the second operating direction 720.

[0223] According to the example, in response to the mold assembly 800 operating from a first operating state (a) to a second operating state (b), the center core 820 can move in a second operating direction 720. As the center core 820 moves in the second operating direction 720, the sliding core 810 can move in a first operating direction 710 (which is the central direction). As an example, the fifth sliding core 810e included in the sliding core 810 can move to the left, and the fourteenth sliding core 810n included in the sliding core 810 can move to the right. As the sliding core 810 moves in the first operating direction 710 (which is the central direction), the second lens barrel (e.g., the second lens barrel 600 of FIG. 5) attached to the molding portion 815 of the mold assembly 800 can be separated.

[0224] According to the example, in response to the mold device 800 operating from the second operating state (b) to the second operating state (b), the center core 820 can move in a direction opposite to the second operating direction 720. As the center core 820 moves in a direction opposite to the second operating direction 720, the sliding core 810 can move in a direction opposite to the first operating direction 710 (which is the opposite of the center direction). As an example, the fifth sliding core 810e included in the sliding core 810 can move to the right, and the fourteenth sliding core 810n included in the sliding core 810 can move to the left. As the sliding core 810 moves in a direction opposite to the first operating direction 710, a second lens barrel (e.g., the second lens barrel 600 of FIG. 5) attached to the molded portion 815 of the mold device 800 can be molded. Corresponding to the embossed cam profile provided in the molded portion 815, at least one cam profile (e.g., the first to third cam profiles 611, 613, 615 of FIG. 5) can be molded in the second lens barrel 600.

[0225] According to the example, when the mold assembly 800 moves, some sliding cores included in the sliding core 810 (e.g., the fifth sliding core 810e or the fourteenth sliding core 810n) can move at different speeds from each other. As an example, an odd number of sliding cores included in the sliding core 810 (e.g., Figure 12 The first sliding core 810a, the third sliding core 810c, ..., the fifteenth sliding core 810p, the seventeenth sliding core 810r) and the even-numbered sliding cores included in the sliding core 810 (e.g., Figure 12 The moving speeds of the second sliding core 810b, the fourth sliding core 810d, ..., the sixteenth sliding core 810o, and the eighteenth sliding core 810q can be different. Therefore, interference can be minimized as the multiple sliding cores 810 included in the mold assembly 800 move in the first operating direction 710. (Refer to...) Figure 22 Described.

[0226] Figure 22 This illustrates a sliding core 810 according to an embodiment of the present disclosure (e.g., the sliding core 810 of FIG. 21) including some sliding cores (e.g., the fifth sliding core 810e and the fourteenth sliding core 810n of FIG. 21) and a center core 820 (e.g., Figure 12 Front view of the central core 820.

[0227] refer to Figure 22 To illustrate that the moving speeds of some sliding cores 810e and 810n differ from those of the central core 820, a portion of Figure 21(b) is enlarged and shown.

[0228] According to the example, in response to the movement of the center core 820 in the second operating direction 720, the fifth sliding core 810e and the fourteenth sliding core 810n, including the sliding core 810, can move in the first operating direction 710 (e.g., the central direction of the mold device 800).

[0229] According to the example, the angle formed between the surface 819f on which the first sliding surface 814e and the second sliding surface 815e of the fifth sliding core 810e and the first sliding surface 831e and the second sliding surface 833e of the third protrusion 821e slide and the first surface S1 can be defined as the first operating angle θ1. Here, the direction in which the first surface S1 extends can correspond to all or some of the optical axis direction L.

[0230] According to the example, the angle between the surface 819n on which the first sliding surface 814n and the second sliding surface 815n formed on the fourteenth sliding core 810n slides and the first sliding surface 831n and the second sliding surface 833n of the seventh recess 821n slides, and the second surface S2 can be defined as the second operating angle θ2. Here, the direction in which the second surface S2 extends can correspond completely or partially to the optical axis direction L. The relationship between the first operating angle θ1 and the second operating angle θ2 can be defined as θ1 > θ2.

[0231] According to the example, in response to the central core 820 moving d in the second operating direction 720, the distance that the fifth sliding core 810e moves in the first operating direction 710 can be defined as l1.

[0232] According to the example, in response to the central core 820 moving d in the second operating direction 720, the distance that the fourteenth sliding core 810n moves in the first operating direction 710 can be defined as l2.

[0233] According to the example, since the angle formed between the second operating direction 720 and the upper surface of the central core 820 corresponds to the vertical angle, l1 can be derived as l1 = d × tan(θ1), and l2 can be derived as l2 = d × tan(θ2). Through the defined relationship between θ1 and θ2, it can be derived that l2 > l1.

[0234] According to the example, in response to the movement of the central core 820 in the second operating direction 720, it can be identified that the distance moved by the fifth sliding core 810e during the same time period is greater than the distance moved by the fourteenth sliding core 810n. Therefore, it can be deduced that odd-numbered sliding cores (e.g., Figure 12 The moving speed of the first sliding core 810a, the third sliding core 810c, ..., the fifteenth sliding core 810p, and the seventeenth sliding core 810r is greater than that of the even-numbered sliding cores (e.g., Figure 12 The moving speed of the second sliding core 810b, the fourth sliding core 810d, ..., the sixteenth sliding core 810o, and the eighteenth sliding core 810q.

[0235] According to the example, by implementing different angles of the inclined surface of the sliding core contacting the center core 820, the moving speeds of the odd-numbered sliding cores 810a, 810c, ..., 810p, 810r and the even-numbered sliding cores 810b, 810d, ..., 810o, 810q can be achieved differently. This minimizes interference between adjacent sliding cores included in the sliding core.

[0236] According to embodiments of the present disclosure, the lens barrel assembly 400 (e.g., Figure 4The lens barrel assembly 400 may include a first lens barrel 500 and a second lens barrel 600. The first lens barrel 500 has at least one protrusion 511, 513, 515 provided on its outer peripheral surface, and the second lens barrel 600 has guide grooves 611, 613, 615 provided in its inner peripheral surface. The guide grooves correspond to a path and have an inner angle of 20° to 30°. The at least one protrusion 511, 513, 515 moves along the path in consideration of the insertion and engagement of the first lens barrel 500. A plurality of parting lines 660a to 660r extending from a first opening surface 601 to a second opening surface 603 may be included in the inner peripheral surface of the second lens barrel 600, with the first opening surface 601 and the second opening surface 603 provided on two opposite sides of the second lens barrel 600. The number of parting lines 660a to 660r may be configured to be 18. However, this disclosure is not limited thereto, and the number of parting lines 660a to 660r may be 18 or more. The lengths of two adjacent first arcs among a plurality of first arcs obtained by dividing a first circumference at a first opening surface 601 using multiple parting lines 660a to 660r can be different from each other.
