Description

Technical Field

[0001] This application relates to the field of electronic device photography technology, and more particularly to an external photography device and an electronic device. Background Technology

[0002] Mobile devices (such as smartphones and tablets) are indispensable in daily life, and users have increasingly higher performance requirements for them, such as image quality. Furthermore, the trend towards thinner and lighter mobile devices leads to a continuous compression of internal space, which hinders the increase of camera module focal length and image sensor size, thus affecting image quality. Summary of the Invention

[0003] This application provides an external shooting device and an electronic device to solve the problem that as mobile terminals become thinner and their internal space is compressed, it is not conducive to increasing the focal length of the camera module and the size of the image sensor, thus affecting the shooting effect of the mobile terminal.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions: In a first aspect, an external imaging device is provided for connection to a mobile terminal. The external imaging device includes a housing, a display device, a control chip, an image sensor, and a lens assembly. The housing has a first surface. The display surface of the display device is disposed on the first surface. The control chip is electrically connected to the display device and is also electrically connected to the mobile terminal. The image sensor is electrically connected to the control chip. The lens assembly is disposed on the side of the housing away from the first surface, with its light-emitting surface facing the image sensor and electrically connected to the control chip.

[0005] The external shooting device provided in the first aspect of this application comprises a lens assembly and an image sensor to form a camera module, and a control chip enables system control to control the lens assembly to perform functions such as focusing. The captured image can then be displayed on a display device, thereby enabling the external shooting device to capture both images and videos, thus forming an independent shooting device.

[0006] Furthermore, the aforementioned external shooting device can be connected to a mobile terminal, enabling it to form a camera module for the mobile terminal. Since the external shooting device is not constrained by the size of the mobile terminal, it is advantageous to increase the focal length and image sensor size of the external shooting device, thereby improving its shooting performance and consequently enhancing the overall shooting capabilities of the mobile terminal.

[0007] In one possible implementation of the first aspect of this application, the external shooting device includes a wireless connection module electrically connected to a control chip, and the wireless connection module is used for electrical connection with a mobile terminal. In this structure, the external shooting device and the mobile terminal are connected via a wireless signal, so that the relative position between the external shooting device and the mobile terminal is unrestricted, facilitating adjustment of their relative position and shooting angle, which is beneficial for improving shooting results.

[0008] In one possible implementation of the first aspect of this application, the wireless connection module includes a Wi-Fi module or a Bluetooth module.

[0009] In one possible implementation of the first aspect of this application, the external shooting device includes a magnetic attachment disposed within the housing, which is used for magnetic connection with a mobile terminal. In this structure, the external shooting device can be magnetically attached to the back cover of the mobile terminal, and the magnetic force is parallel to the thickness direction of the mobile terminal. Therefore, the external shooting device and the mobile terminal can rotate relative to each other along a plane perpendicular to the thickness direction of the mobile terminal, thereby adjusting the relative angle between the external shooting device and the mobile terminal.

[0010] In one possible implementation of the first aspect of this application, the first surface includes a first region and a second region. Along the optical axis of the lens assembly, the first region covers a magnetic attachment member and is used to adhere to a mobile terminal. A display device is disposed in the second region. In this structure, when the external shooting device is attached to the mobile terminal, the first region is adhered to the mobile terminal, and the second region is offset from the mobile terminal, meaning that the display device in the second region can face the user side for easy viewing of the image displayed on the display device.

[0011] In one possible implementation of the first aspect of this application, the external shooting device includes an adapter ring, which is detachably connected to the housing, and the lens assembly is detachably connected to the adapter ring. With this structure, the adapter ring allows the external shooting device to be fitted with lens assemblies of different models and interfaces, thereby expanding the application scenarios of the external shooting device and further improving its shooting quality.

[0012] In one possible implementation of the first aspect of this application, the adapter ring and the housing are engaged by a first snap-fit ​​structure, and the adapter ring is rotatable relative to the housing between a first position and a second position. When the adapter ring is in the first position, the first snap-fit ​​structure prevents relative movement between the adapter ring and the housing along the axial direction of the lens assembly; when the adapter ring is in the second position, the adapter ring and the housing are rotatable relative to each other along the axial direction of the lens assembly. This structure reduces the risk of relative rotation between the adapter ring and the housing during use, ensuring better shooting performance and improving the overall structural reliability.

[0013] In one possible implementation of the first aspect of this application, a first limiting structure is provided between the adapter ring and the housing. When the adapter ring is in the first position, the first limiting structure can prevent the adapter ring from rotating relative to the housing. This structure further reduces the risk of relative rotation between the adapter ring and the housing, which is beneficial for further improving the reliability of the overall structure.

[0014] In one possible implementation of the first aspect of this application, the first limiting structure includes a first limiting post and a first limiting hole. One of the first limiting post and the first limiting hole is disposed on the adapter ring, and the other of the first limiting post and the first limiting hole is disposed on the outer casing. The first limiting post can be inserted into the first limiting hole, and the first limiting post can only move along the axial direction of the lens assembly. In this structure, the axes of both the first limiting post and the first limiting hole are parallel to the optical axis of the lens assembly. Therefore, when the first limiting post is inserted into the first limiting hole, it can restrict the adapter ring and the outer casing from rotating around the optical axis of the lens assembly.

[0015] In one possible implementation of the first aspect of this application, the adapter ring and the lens assembly are engaged via a second locking structure, and the adapter ring is rotatable relative to the lens assembly between a third position and a fourth position. When the adapter ring is in the third position, the second locking structure prevents relative movement between the adapter ring and the lens assembly along the axial direction of the lens assembly; when the adapter ring is in the fourth position, relative movement between the adapter ring and the lens assembly along the axial direction of the lens assembly is permitted. This structure reduces the risk of relative rotation between the adapter ring and the lens assembly during use, ensuring better shooting performance and improving the overall structural reliability.

[0016] In one possible implementation of the first aspect of this application, a second limiting structure is provided between the adapter ring and the lens assembly. When the adapter ring is in the third position, the second limiting structure can prevent the adapter ring from rotating relative to the lens assembly. This structure further reduces the risk of relative rotation between the adapter ring and the lens assembly, thus improving the overall structural reliability.

[0017] In one possible implementation of the first aspect of this application, the second limiting structure includes a second limiting post and a second limiting hole. One of the second limiting post and the second limiting hole is disposed on the adapter ring, and the other of the second limiting post and the second limiting hole is disposed on the lens assembly. The second limiting post is inserted into the second limiting hole, and the second limiting post is movable along the axial direction of the lens assembly. In this structure, the axes of both the second limiting post and the second limiting hole are parallel to the optical axis of the lens assembly. Therefore, when the second limiting post is inserted into the second limiting hole, it can restrict the adapter ring and the lens assembly from rotating around the optical axis of the lens assembly.

[0018] In one possible implementation of the first aspect of this application, the external shooting device includes a wireless charging coil disposed within a housing and electrically connected to a control chip. With this structure, a mobile terminal can reverse charge the external shooting device, thereby improving its battery life.

[0019] In one possible implementation of the first aspect of this application, the external shooting device includes a protective cover. When the lens assembly is not connected to the housing, the protective cover is attached to the side of the housing away from the first surface. In this structure, the protective cover can cover the connection holes on the housing to prevent foreign objects from entering the housing, thereby protecting the electronic components inside the housing. Furthermore, the lens assembly and housing can be stored separately, which improves the portability of the external shooting device.

[0020] Secondly, an electronic device is provided, comprising a mobile terminal and an external shooting device. The mobile terminal includes a housing and a display module. The housing includes a frame and a back cover, and the display module is disposed on the side of the frame away from the back cover. The external shooting device is the external shooting device as described in any of the above technical solutions, wherein the outer shell of the external shooting device is connected to the housing, and a portion of the first surface of the outer shell is attached to the back cover.

[0021] The electronic device provided in the second aspect of this application, by including the external shooting device as described in any of the above technical solutions, is able to solve the same technical problem and achieve the same technical effect.

[0022] In one possible implementation of the second aspect of this application, the external shooting device and the mobile terminal are capable of relative rotation in a plane parallel to the first surface. For example, they are magnetically connected to each other along the thickness direction of the mobile terminal, which is perpendicular to the first surface. Therefore, the external shooting device and the mobile terminal can rotate relative to each other along a plane parallel to the first surface to facilitate adjustment of their relative angle.

[0023] In one possible implementation of the second aspect of this application, the back cover is made of a metal material.

[0024] In one possible implementation of the second aspect of this application, the housing includes a metal component embedded in the rear cover. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0029] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0030] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0031] This application provides a mobile terminal. Specifically, the mobile terminal can be a portable electronic device or other types of terminal equipment. For example, the mobile terminal can be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), monitor, camera, personal computer, laptop computer, wearable device, etc. For ease of explanation, the following description uses a mobile phone as an example.

[0032] Please see Figure 1 and Figure 2 , Figure 1 This is a structural diagram of the mobile terminal 02 provided in the embodiments of this application. Figure 2 This is an exploded view of the mobile terminal 02 provided in an embodiment of this application. As can be seen from the above, in this embodiment, the mobile terminal 02 is a mobile phone, and the mobile terminal 02 can have an approximately rectangular plate-like structure. The mobile terminal 02 may include a display module 10, a housing 20, a circuit board 30, and electronic components.

[0033] For ease of description below, an XYZ coordinate system is established, defining the width direction of mobile terminal 02 as the X-axis, the length direction of mobile terminal 02 as the Y-axis, and the thickness direction of mobile terminal 02 as the Z-axis. It is understood that the coordinate system of mobile terminal 02 can be flexibly set according to actual needs; this application only provides an example and should not be considered a specific limitation thereof. Figure 1 and Figure 2 The mobile terminal 02 is shown only schematically; the actual shape, size, location, and structure of these components are not subject to change. Figure 1 and Figure 2 Restrictions.

[0034] The aforementioned display module 10 is used to display images, videos, etc. The display module 10 may include a light-transmitting cover 11 and a display screen 12 (also known as a display panel), with the light-transmitting cover 11 and the display screen 12 stacked together. The material of the light-transmitting cover 11 includes, but is not limited to, glass. For example, the light-transmitting cover 11 can be a common light-transmitting cover 11, used to protect the display screen 12 from damage caused by external forces and to provide dust protection. Alternatively, the light-transmitting cover 11 can also be a touch-enabled light-transmitting cover 11, enabling the mobile terminal 02 to have touch functionality, thus making it more convenient for users. Therefore, this application does not specifically limit the material of the light-transmitting cover 11.

[0035] Furthermore, the aforementioned display screen 12 can be a flexible display screen or a rigid display screen. For example, the display screen 12 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini light-emitting diode display screen, a micro light-emitting diode display screen, a micro organic light-emitting diode display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

[0036] The aforementioned housing 20 is used to protect the electronic components inside the mobile terminal 02. The housing 20 may include a back cover 21 and a frame 22. The back cover 21 is located on the side of the display screen 12 away from the light-transmitting cover plate 11 and is stacked with the light-transmitting cover plate 11 and the display screen 12. The frame 22 is located between the light-transmitting cover plate 11 and the back cover 21. The frame 22 is fixed to the back cover 21. Exemplarily, the frame 22 can be fixed to the back cover 21 by adhesive bonding, threaded connection, welding, snap-fitting, etc.; alternatively, the frame 22 can also be integrally formed with the back cover 21, i.e., the frame 22 and the back cover 21 form a single structural component. The light-transmitting cover plate 11 can be glued to the frame 22, so that the light-transmitting cover plate 11, the back cover 21, and the frame 22 form a receiving cavity inside the mobile terminal 02, within which the aforementioned circuit board 30 and electronic components are disposed.

[0037] In some embodiments, the housing 20 may further include a middle plate 23, which is disposed within the aforementioned receiving cavity and located on the side of the display screen 12 away from the light-transmitting cover 11. The middle plate 23 is fixedly connected to the frame 22 to form the middle frame of the mobile terminal 02. Exemplarily, the middle plate 23 and the frame 22 can be fixedly connected by adhesive, threaded connection, welding, snap-fit, or other methods; alternatively, the middle plate 23 and the frame 22 can be an integrally formed structure, i.e., the middle plate 23 and the frame 22 form a single structural component. The middle plate 23 divides the aforementioned receiving cavity into two independent spaces. One space is located between the light-transmitting cover 11 and the middle plate 23, and the display screen 12 is located within this space. The other space is located between the middle plate 23 and the rear cover 21, and the circuit board 30 is located within this space.

[0038] The aforementioned circuit board 30 is used to house the electronic components inside the mobile terminal 02 and to achieve electrical connections between the electronic components. The circuit board 30 can be fixed to the middle plate 23 by means of adhesive bonding, threaded connection, soldering, snap-fitting, etc. Therefore, this application does not impose any special limitations on the fixing method of the circuit board 30.

[0039] The aforementioned electronic components are used to implement various functions of the mobile terminal 02. For example, the electronic components may be a SOC chip (System on Chip), a graphics processing unit (GPU), universal flash storage (UFS), a camera module 40, a flash module, and capacitors, resistors, inductors, etc.

[0040] The camera module 40 described above is used to capture video or images. The camera module 40 may include a main camera, a wide-angle camera, and a telephoto camera, etc. For example, please refer to [further details omitted]. Figure 1 and Figure 2 and in conjunction with reference Figure 3 , Figure 3 This is a structural diagram of a camera module 40 provided in an embodiment of this application. The camera module 40 may include an optical lens 41 and a sensor 42. The axis of the optical lens 41 may be parallel to the Z-axis direction. The optical lens 41 may include a light-incident surface 41a. The sensor 42 is distributed along the Z-axis direction with the optical lens 41 and is disposed on the side of the optical lens 41 away from the light-incident surface 41a. The sensor 42 is used to realize optical imaging.

[0041] In some examples, the back cover 21 has a light-transmitting opening 21a. The mobile terminal 02 may also include a camera decorative cover 50, which is fixed at the light-transmitting opening 21a. The camera decorative cover 50 has a light-transmitting window, and the light-incident surface 41a of the optical lens 41 is opposite to the light-transmitting window of the camera decorative cover 50, so that external light can pass through the light-transmitting window and enter the light-incident surface 41a of the optical lens 41, and form an image on the photosensitive surface of the sensor 42, so as to enable the mobile terminal 02 to shoot videos or pictures, and to effectively protect the camera module 40.

[0042] The aforementioned camera module 40 can also capture images of different distances and sizes by adjusting the focal length. For example, the camera module can have an automatic focusing (AF) function to produce different visual effects, and the longer the focal length, the wider the shooting angle. Furthermore, the larger the size of the sensor 42 in the camera module 40, i.e., the larger the area of ​​the photosensitive surface facing the optical lens 41, the wider the shooting angle of the camera module 40 can also be. Therefore, the longer the focal length, the larger the size of the sensor 42, the wider the shooting angle of the camera module 40, and the better the shooting effect.

[0043] However, with the trend of mobile terminals 02 becoming increasingly thinner and lighter, the thickness of mobile terminals 02 is constantly decreasing, that is, the dimension along the Z-axis is constantly decreasing, which causes the space inside the housing 20 to be continuously compressed. Therefore, the installation space of the camera module 40 is continuously compressed, which is not conducive to increasing the focal length of the camera module 40 and the size of the sensor 42.

[0044] To resolve the above issues, please refer to [link / reference]. Figure 4 and Figure 5 , Figure 4 This is a first-view structural diagram of an electronic device 01 provided in an embodiment of this application. Figure 5This is a second-view structural diagram of an electronic device 01 provided in an embodiment of this application. The electronic device 01 includes an external shooting device 03 and the aforementioned mobile terminal 02. The external shooting device 03 can be connected to the back cover 21 of the mobile terminal 02 so that the external shooting device 03 can be used as a rear camera of the mobile terminal 02, thereby improving the shooting effect of the electronic device 01.

[0045] Please refer to Figure 6 , Figure 7 as well as Figure 8 , Figure 6 This is a structural diagram of an external imaging device 03 provided in an embodiment of this application. Figure 7 An exploded view of an external imaging device 03 provided in an embodiment of this application. Figure 8 This is a structural diagram of the internal electronic components of the external imaging device 03 provided in this application embodiment. The external imaging device 03 may include a housing 100, a display device 200, a control chip 310, an image sensor 320, and a lens assembly 400.

[0046] Specifically, the outer casing 100 has a first surface 111, and the display surface of the display device 200 is disposed on the first surface 111. When the external shooting device 03 is connected to the mobile terminal 02, a portion of the first surface 111 (the area where the display device 200 is not disposed) can be attached to the outer surface of the back cover 21 of the mobile terminal 02. The display device 200, the image sensor 320, and the lens assembly 400 are all electrically connected to the control chip 310. The lens assembly 400 is disposed on the side of the outer casing 100 away from the first surface 111.

[0047] In some examples, the housing 100 may include a bottom cover 110 and a top cover 120, which are connected to form an accommodating space. For example, the bottom cover 110 and the top cover 120 may be fixed together by means of screws, snap-fit, or adhesive.

[0048] The surface of the bottom cover 110 that is away from the top cover 120 is the first surface 111. The bottom cover 110 has an installation port 112. The display device 200 can be installed at the installation port 112, and the display surface of the display device 200 faces away from the top cover 120.

[0049] The upper cover 120 has a connecting hole 121 that connects the interior and exterior of the aforementioned accommodating space. The photosensitive surface of the image sensor 320 faces the connecting hole 121. The lens assembly 400 is disposed on the side of the upper cover 120 away from the bottom cover 110, and the optical axis of the lens assembly 400 coincides with the axis of the connecting hole 121, i.e., the two are coaxially arranged, so that external light enters the lens assembly 400 and forms an image on the image sensor 320 to complete the shooting.

[0050] Please continue reading. Figure 6 , Figure 7 as well as Figure 8 The aforementioned external shooting device 03 may also include a motherboard 300, a storage module 330, and a running module 340. The control chip 310, image sensor 320, storage module 330, and running module 340 can all be mounted on the motherboard 300 and electrically connected to each other through the motherboard 300. For example, the control chip 310 can be the aforementioned SOC, the storage module 330 can be an EMMC (Embedded MultiMediaCard), and the running module 340 can be DDR (Double Data Rate Synchronous Dynamic Random Access Memory).

[0051] Furthermore, the display device 200 can be electrically connected to the motherboard 300 via an electrical connector, for example, the electrical connector can be an FPC board (Flexible Printed Circuit).

[0052] Furthermore, to improve image quality, the external shooting device 03 may also include a polarizer 350. The polarizer 350 is disposed on the side of the image sensor 320 away from the motherboard 300, and the polarizer 350 can be fixed to the motherboard 300 via a support frame 351. The image sensor 320 can be disposed within the support frame 351. That is, the image sensor 320, the polarizer 350, and the support frame 351 together form a sensor module. In this structure, after the light is filtered by the polarizer 350, stray light and glare can be eliminated, which is beneficial to improving the image quality of the external shooting device 03.

[0053] The lens assembly 400 and image sensor 320 of the aforementioned external shooting device 03 can form a camera module, and the system is controlled by the control chip 310 to control the lens assembly 400 to perform functions such as focusing. Then, the captured image can be displayed through the display device 200, thereby enabling the external shooting device 03 to capture images and videos, that is, the external shooting device 03 can form an independent device.

[0054] Since the lens assembly 400 and the image sensor 320 are not limited by the space of the mobile terminal 02, the focal length of the lens assembly 400 of the external shooting device 03 can be increased, and the size of the image sensor 320 can also be increased, thereby enabling the external shooting device 03 to have better shooting results.

[0055] When the external shooting device 03 is connected to the mobile terminal 02, the control chip 310 of the external shooting device 03 can be electrically connected to the SOC chip of the mobile terminal 02, so that the mobile terminal 02 can use the lens assembly 400 and image sensor 320 of the external shooting device 03 to take pictures, thereby improving the shooting effect and enhancing the user experience.

[0056] Therefore, users can flexibly choose to use the external shooting device 03 for shooting, or connect the external shooting device 03 to the mobile terminal 02 to improve the shooting effect of the mobile terminal 02. This makes the functions of the electronic device 01 more diversified, thereby further enhancing the user experience.

[0057] Based on this, please continue to refer to Figure 6 , Figure 7 as well as Figure 8 The external shooting device 03 may also have multiple function buttons 500 on its housing 100. These function buttons 500 are electrically connected to the motherboard 300, enabling the adjustment of shooting parameters and the taking of photos. For example, the function buttons 500 may include a power button, a shutter button, a record button, a zoom lever, and a customizable dial, etc., allowing the user to control the external shooting device 03 to take photos.

[0058] Furthermore, when the external shooting device 03 is electrically connected to the mobile terminal 02, the user can take a picture using the function button 500, or the user can also perform a touch operation using the display module 10 of the mobile terminal 02 to complete the shooting. It is understood that the function button 500 and the touch button on the display module 10 have the same priority; both can be used to adjust shooting parameters and take pictures, and the user can flexibly choose based on their usage habits. Therefore, this embodiment does not impose any special limitations on this.

[0059] In some embodiments, please continue reading Figure 6 , Figure 7 as well as Figure 8 The external shooting device 03 provided in this application embodiment may include a wireless connection module 360, such as a Wi-Fi module or a Bluetooth module. The external shooting device 03 can connect to the Wi-Fi module or Bluetooth module of the mobile terminal 02 through the wireless connection module 360, thereby realizing wireless communication between the external shooting device 03 and the mobile terminal 02, so that the mobile terminal 02 can use the external shooting device 03 to take pictures.

[0060] In other possible examples, the external shooting device 03 and the mobile terminal 02 can also be electrically connected in other ways. For example, they can be connected by a data cable, with both ends of the data cable inserted into the USB Type-C port on the external shooting device 03 and the mobile terminal 02, respectively. The C interface enables communication between the external shooting device 03 and the mobile terminal 02.

[0061] It is understood that when using a data cable to connect the external shooting device 03 and the mobile terminal 02, the data cable can form an integrated structure with the external shooting device 03. That is, one end of the data cable is connected to the inside of the external shooting device 03, and the other end is used to connect to the mobile terminal 02. The data cable can also be stored inside the external shooting device 03. Therefore, this application embodiment does not impose any special limitations on this.

[0062] After the external shooting device 03 is powered on, the mobile terminal 02 can select to wirelessly connect to the wireless connection module 360 ​​of the external shooting device 03 via its display interface. After the two are wirelessly connected, please refer to... Figure 9 , Figure 9 This is a schematic diagram of a display interface of an electronic device 01 after power-on, provided in an embodiment of this application. The display module 10 of the mobile terminal 02 displays Image 1 and Image 2. Image 1 is a scene captured by the camera module 40 of the mobile terminal 02, and Image 2 is a scene captured by the lens assembly 400 of the external shooting device 03. By default, Image 2 is presented as a thumbnail on the display module 10; for example, the thumbnail of Image 2 can be located in the upper left or upper right corner of Image 1. Simultaneously, Image 2 is displayed on the display device 200 of the external shooting device 03.

[0063] That is, electronic device 01 uses the camera module 40 of mobile terminal 02 to take pictures by default. At this time, the user can click on the display module 10 of mobile terminal 02 (click on the area where image 2 is located) to swap the positions of image 2 and image 1. Please refer to [link to relevant documentation]. Figure 10 , Figure 10 This is a schematic diagram of another display interface of the electronic device 01 after it is powered on, provided in the embodiments of this application. That is, image 1 is presented as a thumbnail in the upper left or upper right corner of image 2, so that the electronic device 01 can use the external shooting device 03 to take pictures, thereby improving the shooting quality of the electronic device 01.

[0064] In some examples, the display device 200 of the external shooting device 03 can also serve as an extended screen for the mobile terminal 02, thereby increasing the display area. Furthermore, the user can choose whether or not to use the display device 200 of the external shooting device 03 as an extended screen, which improves the user experience. Therefore, this application does not impose any special limitations in this regard.

[0065] In some embodiments, please refer to Figure 11 and Figure 12 , Figure 11 This is a first-view structural diagram of another electronic device 01 provided in an embodiment of this application. Figure 12 for Figure 11 An exploded view of the provided electronic device 01. In this electronic device 01, the external imaging device 03 may also include a magnetic member 600, which is disposed within the aforementioned housing 100.

[0066] In this way, the external shooting device 03 can be attached to the mobile terminal 02 via the magnetic attachment 600, so that the user can take pictures using the external shooting device 03. For example, the magnetic attachment 600 can be fixed to the inner surface of the bottom cover 110, and the external shooting device 03 can be attached to the outer surface of the back cover 21 of the mobile terminal 02, that is, the external shooting device 03 forms the rear camera of the mobile terminal 02.

[0067] In this way, under the attraction of the magnetic component 600, the external shooting device 03 and the mobile terminal 02 are relatively fixed, forming an integral structure. Therefore, without external interference, the external shooting device 03 and the mobile terminal 02 will not move relative to each other, thus ensuring the user's shooting effect.

[0068] Furthermore, since the external shooting device 03 and the mobile terminal 02 are mutually attracted and fixed, that is, the first surface 111 of the external shooting device 03 and the outer surface of the back cover 21 are mutually attracted and attached, and the attraction force is parallel to the Z-axis direction, the external shooting device 03 and the mobile terminal 02 can move relative to each other in a direction parallel to the XY plane. That is, the two can rotate relative to each other around the optical axis of the lens assembly 400 (the optical axis is parallel to the Z-axis direction) to adjust the angle of the shooting image, thereby further improving the user's shooting experience.

[0069] In some examples, the housing 100 of the external shooting device 03 may include a first part 100a and a second part 100b. The magnetic 600 and lens assembly 400 are both disposed on the first part 100a, and the display device 200 and function buttons 500 are both disposed on the second part 100b. The second part 100b can serve as a handle so that the user can hold the external shooting device 03.

[0070] For example, please continue reading Figure 11 and Figure 12 The distribution direction of the first part 100a and the second part 100b of the outer casing 100 can also be parallel to the X-axis direction, that is, the mobile terminal 02 forms a vertical structure, and under this structure, please refer to Figure 13 , Figure 13This is a schematic diagram of another display interface of the electronic device 01 provided in this application embodiment after it is powered on. Alternatively, please refer to the previous section. Figure 4 and Figure 5 The first part 100a and the second part 100b of the outer casing 100 can be distributed parallel to the Y-axis direction, that is, the mobile terminal 02 forms a horizontal structure, and in this case, the display interface of the electronic device 01 after powering on is as follows: Figure 9 and Figure 10 As shown.

[0071] In other possible examples, the distribution directions of the first part 100a and the second part 100b can be arranged at a 45° angle to the X-axis direction, so that the mobile terminal 02 remains stationary while the screen displayed on the mobile terminal 02 (such as...) Figure 9 and Figure 10 The scene shown in Image 1 or Image 2 is tilted at 45°, which enhances the diversity of shooting effects and improves the user experience.

[0072] Based on this, please continue to refer to Figure 11 and Figure 12 and in conjunction with reference Figure 14 and Figure 15 , Figure 14 This is a structural diagram of the outer casing 100 provided in an embodiment of this application. Figure 15 This is a second-view structural diagram of another electronic device 01 provided in an embodiment of this application. The first surface 111 of the housing 100 may include a first region 111a and a second region 111b. The first region 111a is located in the first portion 100a, and the second region 111b is located in the second portion 100b. That is, the first region 111a covers the aforementioned magnetic member 600 and is used to adhere to the rear cover 21. The display surface of the display device 200 is located within the second region 111b.

[0073] To enhance the adhesion between the external shooting device 03 and the mobile terminal 02, in some examples, multiple magnetic components 600 may be provided, and these multiple magnetic components 600 are distributed around the optical axis of the lens assembly 400, that is, the geometric center of the annular structure formed by the magnetic components 600 is located on the optical axis of the lens assembly 400. For example, multiple magnetic components 600 may form a circular structure, and the circle of this circular structure is located on the optical axis of the lens assembly 400.

[0074] In this way, the magnetic attachment 600 is distributed around the optical axis of the lens assembly 400 so that when the external shooting device 03 and the mobile terminal 02 are attracted to each other, the vertical projection on the XY plane shows that the lens assembly 400 and the magnetic attachment 600 can overlap. That is, the attraction force between the external shooting device 03 and the mobile terminal 02 can ensure that the first part 100a where the lens assembly 400 is located and the mobile terminal 02 cannot easily move relative to each other, thereby ensuring the shooting effect of the electronic device 01 composed of the external shooting device 03 and the mobile terminal 02.

[0075] In other examples, the back cover 21 of the mobile terminal 02 may be made of metal so that the external shooting device can be attached to the back cover 21. Alternatively, a metal component may be provided inside the back cover 21 of the mobile terminal 02. For example, the metal component may be fixed to the inner surface of the back cover 21, or the metal component may be embedded inside the back cover 21, and the surface of the metal component may be exposed on the outer surface of the back cover 21 and flush with the outer surface of the back cover 21, so that the user can more easily identify the area where the metal component is located, so as to attach the external shooting device 03 to the mobile terminal 02.

[0076] Furthermore, in the XY plane, the coverage area of ​​the metal part can be greater than or equal to the area of ​​the magnetic 600. For example, when the magnetic 600 forms the above-mentioned ring structure, the coverage area of ​​the metal part can be greater than the area enclosed by the outer edge of the ring structure formed by the magnetic 600, which helps to ensure the adsorption reliability between the mobile terminal 02 and the external shooting device 03.

[0077] In other possible examples, the shape of the metal part in the XY plane can also be formed into a ring structure that is exactly the same as that of the magnetic accumulator 600, for example, both can form a circular ring structure. Therefore, this application does not impose any special limitations on this.

[0078] In some embodiments, please continue reading Figures 11-15 The external shooting device 03 provided in this application embodiment may further include a wireless charging coil 700. The wireless charging coil 700 is disposed inside the housing 100 and is electrically connected to the motherboard 300, that is, the wireless charging coil 700 is electrically connected to the control chip 310. For example, the wireless charging coil 700 may be disposed within the annular structure formed by the magnetic member 600 and coaxially disposed with the annular structure formed by the magnetic member 600.

[0079] In this case, after the external shooting device 03 is connected to the mobile terminal 02, the wireless charging coil 700 can be coupled with the charging coil inside the mobile terminal 02, so that the mobile terminal 02 can charge the external shooting device 03, thereby improving the battery life of the external shooting device 03 and enhancing the user experience.

[0080] For example, while the external shooting device 03 is attached to the mobile terminal 02 and an electrical connection is established between the external shooting device 03 and the mobile terminal 02 via the wireless connection module 360, the mobile terminal 02 can wirelessly charge the external shooting device 03. Alternatively, the user can control whether to wirelessly charge the external shooting device 03 through the software program of the mobile terminal 02. Therefore, this embodiment of the application does not limit this.

[0081] Based on the above embodiments, in order to enable the external shooting device 03 to use different lens assemblies 400 to adapt to different shooting environments, the lens assembly 400 and the housing 100 provided in this application embodiment can be connected in a detachable manner to facilitate the replacement of different lens assemblies 400. For example, the lens assembly 400 and the housing 20 can be snapped together and fixed.

[0082] Furthermore, since the dimensions of different lens assemblies 400 may not be exactly the same, please refer to [link / reference needed] to ensure that the housing 100 can snap into different lens assemblies 400. Figure 16 , Figure 16 The exploded view of an electronic device 01 provided in the embodiment of this application shows that the external shooting device 03 may further include an adapter ring 800, which is snapped into the housing 100 and the lens assembly 400.

[0083] In some embodiments, please refer to Figure 17 , Figure 17 The exploded view of the adapter ring 800 and the housing 100 provided in the embodiments of this application should be noted as follows: Figure 17 The coordinate system shown is Figure 4 The coordinate system shown is the same, Figure 17 The coordinate system shown is only an example, and it can be flexibly changed based on the setting position of the mobile terminal 02.

[0084] The adapter ring 800 is engaged with the housing 100 via a first snap-fit ​​structure 900, and the adapter ring 800 is rotatable relative to the housing 100 between a first position and a second position. When the adapter ring 800 is in the first position, the first snap-fit ​​structure 900 prevents relative movement between the adapter ring 800 and the housing 100 along the axial direction (i.e., the Z-axis direction) of the lens assembly 400. When the adapter ring 800 is in the second position, relative movement between the adapter ring 800 and the housing 100 is possible along the Z-axis direction.

[0085] For example, the first snap-fit ​​structure 900 includes a first protrusion 810 and a first groove 122. The first protrusion 810 is disposed on the end face of the adapter ring 800 facing the housing 100, and the first groove 122 is formed on the surface of the housing 100 (i.e. the top cover 120) facing the adapter ring 800. For example, the first groove 122 may extend circumferentially around the connecting hole 121.

[0086] Please continue reading. Figure 17 and in conjunction with reference Figure 18 and Figure 19 , Figure 18 for Figure 17 The provided structural diagram of the 800 adapter ring Figure 19 for Figure 18 Enlarged view of region A structure. A first snap-fit ​​protrusion 811 is provided on the first protrusion 810, and a first snap-fit ​​groove 812 is formed between the first snap-fit ​​protrusion 811 and the end face of the adapter ring 800.

[0087] Please continue reading. Figures 17-19 and in conjunction with reference Figure 20 and Figure 21 , Figure 20 for Figure 17 The provided structural diagram of the outer casing 100, Figure 21 for Figure 20 An enlarged view of the structure of region B. A second engaging protrusion 123 is provided on the inner wall of the first groove 122, and a second engaging groove 124 is formed between the second engaging protrusion 123 and the bottom surface of the first groove 122. Both the first engaging protrusion 811 and the second engaging protrusion 123 extend around the circumference of the lens assembly 400, that is, both the first engaging groove 812 and the second engaging groove 124 extend along the circumference of the lens assembly 400.

[0088] When the adapter ring 800 is connected to the outer shell 100, the first protrusion 810 extends into the first groove 122, and along the Z-axis direction, the first snap-fit ​​protrusion 811 and the second snap-fit ​​protrusion 123 do not overlap with each other. That is, in the XY plane, the first snap-fit ​​protrusion 811 and the first snap-fit ​​groove 812 are staggered. At this time, the adapter ring 800 is in the second position mentioned above.

[0089] Rotate the adapter ring 800 to move it circumferentially around the lens assembly 400 (e.g., clockwise or counterclockwise). The first locking protrusion 811 extends into the second locking groove 124, and the second locking protrusion 123 extends into the first locking groove 812. That is, the first locking protrusion 811 and the second locking protrusion 123 are distributed along the Z-axis, with the first locking protrusion 811 located on the side of the second locking protrusion 123 away from the lens assembly 400, and the second locking protrusion 123 located on the side of the first locking protrusion 811 closer to the lens assembly 400, thereby preventing relative movement between the adapter ring 800 and the housing 100 along the Z-axis. At this time, the adapter ring 800 is in the aforementioned first position.

[0090] Furthermore, a limiting portion 812a may be provided in at least one of the first latching groove 812 and the second latching groove 124. For example, the limiting portion 812a is provided in the first latching groove 812, and is located at the end of the first latching groove 812 along the circumferential direction of the lens assembly 400. This allows the second latching protrusion 123 to abut against the limiting portion 812a when the adapter ring 800 rotates from the second position to the first position, preventing the adapter ring 800 from continuing to rotate. Furthermore, when the adapter ring 800 is in the first position, it can only rotate from the first position to the second position, thereby further improving the reliability of the overall structure.

[0091] It is understood that only one set of first snap-fit ​​structures 900 may be provided between the adapter ring 800 and the housing 100. To ensure proper installation, the arc of the first snap-fit ​​structure 900 extending circumferentially around the lens assembly 400 can be less than 180°. Alternatively, multiple sets of first snap-fit ​​structures 900 may be provided between the adapter ring 800 and the housing 100, and these multiple sets of snap-fit ​​structures may be evenly distributed circumferentially around the lens assembly 400, which helps to improve the reliability of the interlocking between the two. Therefore, this application embodiment does not impose any special limitations on the number or specific structural dimensions of the first snap-fit ​​structures 900.

[0092] Based on this, please continue to refer to Figures 17-21 A first limiting structure 910 may also be provided between the adapter ring 800 and the housing 100. When the adapter ring 800 is in the first position, the first limiting structure 910 can prevent the adapter ring 800 from rotating circumferentially around the lens assembly 400 relative to the housing 100.

[0093] In some examples, the first limiting structure 910 may include a first limiting post 820 and a first limiting hole 125. One of the first limiting post 820 and the first limiting hole 125 is disposed on the adapter ring 800, and the other of the first limiting post 820 and the first limiting hole 125 is disposed on the housing 100. The axial directions of both the first limiting post 820 and the first limiting hole 125 are parallel to the Z-axis direction. The first limiting post 820 can be inserted into the first limiting hole 125, and the first limiting post 820 can only move along the Z-axis direction.

[0094] In this way, when the adapter ring 800 rotates to the first position, the first limiting post 820 is inserted into the first limiting hole 125, preventing the adapter ring 800 from rotating circumferentially around the lens assembly 400 relative to the housing 100. That is, the first limiting structure 910 locks the adapter ring 800 in the first position to prevent the adapter ring 800 and lens assembly 400 from rotating relative to the housing 100 during shooting, thus avoiding affecting the shooting effect. When the first limiting post 820 disengages from the first limiting hole 125, the adapter ring 800 can rotate from the first position to the second position to facilitate the replacement of the lens assembly 400.

[0095] To facilitate control of the movement of the first limiting post 820, the first limiting structure 910 may further include a first switch 830, which is fixedly connected to the first limiting post 820. The user can control the movement of the first limiting post 820 along the Z-axis using the first switch 830. For example, the first switch 830 may be located on the side wall of the adapter ring 800, meaning the first limiting post 820 is located inside the adapter ring 800, and the first limiting hole 125 is formed on the outer casing 100.

[0096] In some examples, please refer to Figure 22 , Figure 22 for Figure 18 A partial cross-sectional view of the provided adapter ring 800 is shown. The adapter ring 800 has a first receiving groove 840 and a second receiving groove 841. The first receiving groove 840 extends along the Z-axis, and the second receiving groove 841 is perpendicular to and communicates with the first receiving groove 840. A first limiting post 820 is disposed within the first receiving groove 840. A portion of a first switch 830 is disposed within the second receiving groove 841 and is fixedly connected to the first limiting post 820. A portion of the first switch 830 is located outside the second receiving groove 841 and is disposed on the side wall of the adapter ring 800. In this structure, the first switch 830 can be pushed along the Z-axis to move the first limiting post 820 along the Z-axis, thereby locking and unlocking the rotating ring.

[0097] For other possible examples, please refer to [link / reference needed]. Figure 22The aforementioned first limiting structure 910 may further include an elastic element 850, which abuts against the bottom surface of the first limiting post 820 and the first receiving groove 840. When the first limiting post 820 disengages from the first limiting groove, it can compress the elastic element 850, causing the elastic element 850 to undergo elastic deformation. That is, the elastic force generated by the elastic element 850 can keep the first limiting post 820 within the first limiting hole 125. Therefore, under the action of the elastic force of the elastic element 850, the risk of accidental activation causing the first switch 830 to move the first limiting post 820 can be reduced, which is beneficial to improving the reliability of the overall structure.

[0098] In other embodiments, please refer to Figure 23 , Figure 24 as well as Figure 25 , Figure 23 This is an exploded view of the adapter ring 800 and lens assembly 400 provided in the embodiments of this application. Figure 24 for Figure 23 The provided structural diagram of the 800 adapter ring Figure 25 for Figure 23 The provided structural diagram of the lens assembly 400.

[0099] The adapter ring 800 and the lens assembly 400 are engaged via a second locking structure 920, and the adapter ring 800 can rotate relative to the lens assembly 400 between a third position and a fourth position. When the adapter ring 800 is in the third position, the second locking structure 920 prevents relative movement between the adapter ring 800 and the lens assembly 400 along the Z-axis. When the adapter ring 800 is in the fourth position, relative movement between the adapter ring 800 and the lens assembly 400 is permitted along the Z-axis.

[0100] For example, the end of the lens assembly 400 can be interlocked with the end face of the adapter ring 800, that is, the second snap-fit ​​structure 920 includes a second protrusion 410 formed at the end of the lens assembly 400 and a second groove 860 formed on the end face of the adapter ring 800. A third snap-fit ​​protrusion 411 is provided on the second protrusion 410, and a third snap-fit ​​groove 412 is formed between the third snap-fit ​​protrusion 411 and the end face of the lens assembly 400. A fourth snap-fit ​​protrusion 861 is provided on the inner wall of the second groove 860, and a fourth snap-fit ​​groove 862 is formed between the fourth snap-fit ​​protrusion 861 and the bottom surface of the second groove 860. Both the third snap-fit ​​protrusion 411 and the fourth snap-fit ​​protrusion 861 extend around the circumference of the lens assembly 400, that is, both the third snap-fit ​​groove 412 and the fourth snap-fit ​​groove 862 extend along the circumference of the lens assembly 400.

[0101] When the adapter ring 800 is in the third position described above, the third locking protrusion 411 is inserted into the fourth locking groove 862, and the fourth locking protrusion 861 is inserted into the third locking groove 412. That is, the third locking protrusion 411 and the fourth locking protrusion 861 are distributed along the Z-axis direction, with the third locking protrusion 411 located on the side of the fourth locking protrusion 861 closer to the outer shell 100, and the fourth locking protrusion 861 located on the side of the third locking protrusion 411 away from the outer shell 100. When the adapter ring 800 is in the fourth position described above, the third locking protrusion 411 and the fourth locking protrusion 861 are staggered in the XY plane.

[0102] Furthermore, at least one of the third and fourth slots 412 may be provided with the aforementioned limiting part 812a, so that when the adapter ring 800 rotates to the third position, it cannot continue to rotate and can only rotate from the third position to the fourth position, thereby improving the reliability of the overall structure.

[0103] It is understandable that, since the second snap-fit ​​structure 920 is similar to the first snap-fit ​​structure 900 described above, that is, the movement of the adapter ring 800 relative to the lens assembly 400 between the third and fourth positions is the same as the movement of the adapter ring 800 relative to the housing 100 between the first and second positions, this will not be repeated.

[0104] Furthermore, only one set of second snap-fit ​​structures 920 may be provided between the adapter ring 800 and the lens assembly 400. To ensure proper installation, the arc of the second snap-fit ​​structure 920 extending circumferentially around the lens assembly 400 can be less than 180°. Alternatively, multiple sets of second snap-fit ​​structures 920 may be provided between the adapter ring 800 and the lens assembly 400, and these multiple sets of snap-fit ​​structures can be evenly distributed circumferentially around the lens assembly 400, which helps improve the reliability of the interlocking between the two. Therefore, this application embodiment does not impose any special limitations on the number or specific structural dimensions of the first snap-fit ​​structures 900.

[0105] Based on this, please continue to refer to Figure 23 , Figure 24 as well as Figure 25 A second limiting structure 930 may be provided between the adapter ring 800 and the lens assembly 400. When the adapter ring 800 is in the third position, the second limiting structure 930 can prevent the adapter ring 800 from rotating circumferentially relative to the lens assembly 400.

[0106] In some examples, the second limiting structure 930 may include a second limiting post 870 and a second limiting hole 420, one of which is disposed on the adapter ring 800, and the other is disposed on the lens assembly 400. The axes of both the second limiting post 870 and the limiting hole 420 are parallel to the Z-axis direction. The second limiting post 870 can be inserted into the second limiting hole 420, and the second limiting post 870 can only move along the Z-axis direction.

[0107] In this way, when the adapter ring 800 rotates to the third position, the second limiting post 870 is inserted into the second limiting hole 420, preventing the adapter ring 800 from rotating circumferentially around the lens assembly 400 relative to the housing 100. That is, the second limiting structure 930 locks the adapter ring 800 in the third position to prevent the adapter ring 800 and lens assembly 400 from rotating relative to the housing 100 during shooting, thus avoiding affecting the shooting effect. When the second limiting post 870 disengages from the second limiting hole 420, the adapter ring 800 can rotate from the third position to the fourth position to facilitate the replacement of the lens assembly 400.

[0108] To facilitate control of the movement of the second limit post 870, the second limit structure 930 may also include a second switch 880, which is fixedly connected to the second limit post 870. The user can control the movement of the second limit post 870 along the Z-axis through the second switch 880.

[0109] For example, the second switch 880 can also be disposed on the side wall of the adapter ring 800, that is, the second limiting post 870 is disposed inside the adapter ring 800, and the second limiting hole 420 is formed on the lens assembly 400. Furthermore, the connection structure between the second switch 880 and the second limiting post 870 can adopt the same connection structure as the first switch 830 and the first limiting post 820 described above; therefore, this will not be repeated.

[0110] Furthermore, the aforementioned second limiting structure 930 may also include Figure 22 The elastic element 850 shown reduces the risk of accidental activation causing the second switch 880 to move the second limit post 870 under the action of the elastic force of the elastic element 850, which helps to improve the reliability of the overall structure.

[0111] In other possible examples, the first switch 830 may be located on the housing 100 and the second switch 880 may be located on the lens assembly 400. Therefore, this application embodiment does not impose any special limitations on this.

[0112] Based on the above embodiments, please continue to refer to Figure 24 and Figure 25The adapter ring 800 may have multiple electrical connection portions 890 on the side facing the lens assembly, and the lens assembly 400 may have multiple electrical connection points 430 on its end face. After the lens assembly 400 and the adapter ring 800 are engaged, that is, when the adapter ring 800 is in the third position relative to the lens assembly 400, the multiple electrical connection portions 890 and the multiple electrical connection points 430 abut against each other one by one, so that the lens assembly 400 and the adapter ring 800 are electrically connected.

[0113] Furthermore, when the adapter ring 800 is connected to the housing 100, i.e., when the adapter ring 800 is in the first position relative to the housing 100 as described above, the lens assembly 400 and the housing 100 are also electrically connected by the structure of the electrical connection portion 890 and the electrical connection point 430 abutting against each other. The electrical connection point 430 provided on the housing 100 is electrically connected to the motherboard 300. Moreover, the electrical connection portions 890 on both sides of the adapter ring 800 are electrically connected to each other, thereby enabling the lens assembly 400 to be electrically connected to the motherboard 300.

[0114] In other embodiments, please refer to Figure 26 and Figure 27 , Figure 26 This is a structural diagram of a housing 100 provided in an embodiment of this application. The external shooting device 03 provided in this embodiment may further include a protective cover 940, which is used to connect with the upper cover 120 of the housing 100. Exemplarily, when the external shooting device 03 needs to be stored, the lens assembly 400 can be separated from the housing 100 and stored separately, thereby better protecting the lens assembly 400.

[0115] Therefore, without the lens assembly 400 installed, the protective cover 940 can be installed on the top cover 120, covering the connecting hole 121 on the top cover 120. In this way, the connecting hole 121 on the top cover 120 is not exposed, thereby preventing foreign objects from entering the housing 100 and providing effective protection for the image sensor 320.

[0116] In some examples, please refer back to the documentation. Figure 18 and Figure 26 and in conjunction with reference Figure 27 and Figure 28 , Figure 27 This is a structural diagram of the protective cover 940 provided in an embodiment of this application. Figure 28 for Figure 27 An enlarged view of the C region structure. The protective cover 940 has a first protrusion 810 and a first snap-fit ​​protrusion 811. A first snap-fit ​​groove 812 is formed between the first snap-fit ​​protrusion 811 and the end face of the protective cover 940, meaning the protective cover 940 and the upper cover 120 can be connected via... Figure 17 The first snap-fit ​​structure shown is the 900 snap-fit.

[0117] In this structure, the first protrusion 810 on the protective cover 940 is inserted into the first groove 122 on the upper cover 120, and the protective cover 940 is rotated so that the first snap-fit ​​protrusion 811 is inserted into the second snap-fit ​​groove 124, and the second snap-fit ​​protrusion 123 is inserted into the first snap-fit ​​groove 812, thereby realizing the mutual snap-fit ​​between the protective cover 940 and the upper cover 120.

[0118] Furthermore, a space can be provided between the protective cover 940 and the upper cover 120. Figure 19 and Figure 21 The first limiting structure 910 shown, namely the protective cover 940, is provided with the aforementioned first limiting post 820 and first switch 830, which helps to improve the connection reliability between the protective cover 940 and the upper cover 120.

[0119] In other possible examples, the protective cover 940 and the upper cover 120 may also be provided with other snap-fit ​​structures, or connected by other means. Therefore, the embodiments of this application do not impose any special limitations on this.
