Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to an electronic device. Background Technology

[0002] Mobile phones, tablets and other electronic devices play a very important role in people's daily lives. These devices can integrate camera functions, and people have increasingly higher requirements for the photo quality of these devices.

[0003] Electronic devices include cameras. When the built-in camera of an electronic device cannot meet the user's needs, an external imaging device can be connected to the device. This external imaging device can improve the image quality. The external imaging device can be mounted on the housing of the electronic device. However, the installation and removal process of the external imaging device from the housing is relatively complex.

[0004] The complex installation and removal of external imaging devices increases the failure rate of electronic devices and results in a poor user experience. Summary of the Invention

[0005] This application provides an electronic device that avoids users having to repeatedly disassemble or rotate the device to align the lens mount and camera, thereby reducing the failure rate of the electronic device and providing users with a better user experience.

[0006] A first aspect of this application provides an electronic device, including: a housing, a camera module, and an adapter. The housing includes a first mounting portion with a through hole. The camera module is disposed inside the housing and opposite to the through hole, and includes at least one camera. The adapter has a second mounting portion on its side facing the housing, which is used to connect to the first mounting portion. The adapter has at least one lens mounting portion on its side away from the housing, which is used to mount an external imaging accessory. A first positioning portion is provided on one of the adapter and the housing, and a second positioning portion is provided on the other. The first positioning portion and the second positioning portion engage so that the lens mounting portion is opposite to the camera.

[0007] When installing the adapter to the housing, the adapter is brought close to the housing, with the first mounting part and the second mounting part ready to connect. Then, the adapter is rotated circumferentially relative to the housing until the first positioning part and the second positioning part engage. When the first positioning part and the second positioning part engage, the first mounting part and the second mounting part connect. Through the first positioning part and the second positioning part, the user can feel the engagement of the first positioning part and the second positioning part during adapter installation. This stops rotating the adapter and avoids the user having to repeatedly disassemble or rotate it to align the lens mounting part and the camera, reducing the probability of misalignment between the lens mounting part and the camera during adapter installation. This reduces the error rate of adapter installation with the housing, thereby reducing the failure rate of electronic devices and the user's learning time, resulting in a better user experience.

[0008] In some possible implementations, one of the first mounting portion and the second mounting portion is provided with a first mounting protrusion, and the other is provided with a first mounting groove corresponding to the first mounting protrusion. The first mounting groove includes a first engaging section and a first limiting section. At a first position, the first mounting protrusion aligns with the first engaging section to enter into the first engaging section. When the adapter rotates circumferentially relative to the housing to a second position, the first mounting protrusion engages with the first limiting section, and the first positioning portion engages with the second positioning portion. Thus, when installing the adapter, aligning the first mounting protrusion with the first engaging section can pre-align the adapter. When disassembling the adapter, rotating the adapter until the first mounting protrusion aligns with the first engaging section is sufficient, thereby further reducing the number of times the user needs to rotate the adapter.

[0009] In some possible implementations, the first positioning part is a positioning protrusion protruding axially, and the second positioning part is an elongated hole corresponding to the positioning protrusion. The elongated hole extends circumferentially, and its circumferential dimension is larger than that of the positioning protrusion. The elongated hole includes a first end and a second end arranged circumferentially. At the first position, the positioning protrusion is aligned with the first end of the elongated hole and inserted into the elongated hole at the first end. When the adapter rotates relative to the housing to the second position, the positioning protrusion rotates relative to the elongated hole to the second end. Through the cooperation of the positioning protrusion and the elongated hole, the adapter can be positioned without affecting its rotation relative to the housing.

[0010] In some possible implementations, the first positioning part is an axially protruding elastic component; the second positioning part is an axially recessed positioning groove; at the second position, the elastic component elastically abuts against the positioning groove. Thus, the user can determine that the adapter is installed correctly based on the decrease in resistance and the accompanying sound, providing a better user experience.

[0011] In some possible implementations, the elastic component includes an elastic element and a ball bearing; the first positioning part further includes a limiting post having an axially extending mounting hole, where both the elastic element and the ball bearing are located, with the ball bearing facing the positioning groove; under the elastic force of the elastic element, the ball bearing abuts against the inner wall of the positioning groove. When the adapter rotates relative to the housing, the ball bearing can roll along with the rotation of the adapter, thereby reducing wear on the ball bearing and improving the service life of the first and second positioning parts.

[0012] In some possible implementations, the diameter of the end of the mounting hole facing the positioning groove is smaller than the diameter of the ball, so as to confine the ball within the mounting hole. This prevents the ball from slipping out of the mounting hole.

[0013] In some possible implementations, the first engaging section includes an opening and a first slot communicating with the opening, and the first limiting section includes a second slot and a limiting wall, with the second slot communicating with the first slot. In a first position, the first mounting protrusion enters the first slot through the opening; in a second position, the first mounting protrusion enters the second slot and engages with the limiting wall. Since the first mounting protrusion is a circumferentially extending protrusion, and the limiting wall is also a circumferentially extending limiting wall, when the mounting component rotates relative to the housing until the first mounting protrusion enters the second slot, the limiting wall can limit the first mounting protrusion. Since both the limiting wall and the first mounting protrusion extend circumferentially, it is possible to avoid increasing the size of the electronic device along the thickness direction (i.e., the axial direction), and the adapter can be removed from the housing simply by rotating it, making the disassembly of the adapter more convenient.

[0014] In some possible implementations, a limiting component is also included. This limiting component comprises a limiting protrusion and a limiting groove. Both the limiting protrusion and the first mounting protrusion are located on the first mounting portion and protrude radially from it. The limiting groove is located on the limiting wall and is recessed radially from the end face of the limiting wall. When the adapter rotates relative to the housing to the second position, the limiting protrusion is located in the limiting groove. The limiting protrusion enters the limiting groove, at which point the user experiences a sudden decrease in resistance. This sudden decrease in resistance indicates that the adapter is properly installed, thus providing a better user experience when installing the adapter.

[0015] In some possible implementations, the limiting protrusion and the first mounting protrusion are circumferentially spaced on the first mounting portion; the first mounting protrusion has a first sidewall facing the limiting protrusion and a second sidewall facing away from the limiting protrusion, the circumferential distance between the second sidewall and the limiting protrusion being less than or equal to the circumferential dimension of the first engaging section. At the first position, both the limiting protrusion and the first mounting protrusion enter the first slot through the opening of the first engaging section, thereby preventing interference between the limiting wall and the limiting protrusion at the first position.

[0016] In some possible implementations, the axial dimension of the limiting protrusion is greater than or equal to the axial dimension of the limiting wall. This increases the contact area between the limiting protrusion and the limiting wall, thereby increasing the resistance exerted by the limiting protrusion on the rotation of the adapter. During rotation, the user experiences increased resistance, and the reduction in resistance is more pronounced when the limiting protrusion enters the limiting groove, further enhancing the user experience.

[0017] In some possible implementations, the end of the limiting wall facing the first slot is provided with a rounded corner. This can reduce the probability of user misjudgment and further improve the user experience.

[0018] In some possible implementations, the first mounting groove has a third sidewall opposite to the second sidewall, and at the second position, the third sidewall abuts against the second sidewall. The abutment between the second and third sidewalls, along with the engagement between the first and second positioning parts, works together to limit the adapter's position, thus better enabling the adapter to fulfill its limiting function. Even if either the abutment between the second and third sidewalls or the engagement between the first and second positioning parts fails, the adapter can still be ensured to stop rotating at the second position, further enhancing the user experience.

[0019] In some possible implementations, there are at least two first mounting slots, which are spaced apart circumferentially; first mounting protrusions are provided in a one-to-one correspondence with the first mounting slots. This prevents the adapter from detaching from the housing.

[0020] In some possible implementations, the axial dimensions of the first mounting protrusion and the second slot are configured to allow for a clearance fit. This results in less resistance to rotation of the adapter when the adapter rotates relative to the housing until the first mounting protrusion is within the second slot.

[0021] In some possible implementations, the adapter is provided with a first clearance hole, and the electronic device also includes a signal transmitting device. At a second position, the first clearance hole corresponds to the position of the signal transmitting device. This can prevent the adapter from interfering with the signal transmission of the electronic device.

[0022] In some possible implementations, the adapter is provided with a second clearance hole, and the camera module also includes a flash. At a second position, the second clearance hole is aligned with the flash. This prevents the adapter from blocking the flash light, thereby improving shooting results.

[0023] In some possible implementations, the lens mounting portion includes a second mounting groove, which includes a second snap-in section and a second limiting section. The second mounting groove is configured to mount a second mounting protrusion in an external imaging accessory, such that the second mounting protrusion enters the second mounting groove from the second snap-in section and is rotatable relative to the second mounting groove until the second mounting protrusion engages with the second limiting section.

[0070] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0071] Electronic devices include cameras. When the built-in camera of an electronic device cannot meet the user's needs, an external imaging device can be connected. This external imaging device can improve the image quality. The external imaging device can be mounted on the housing of the electronic device using an adapter. Electronic devices may include multiple cameras, and the external imaging device needs to be mounted on the housing of the electronic device via an adapter and aligned with one of the cameras. Therefore, the user needs to try installing the adapter multiple times to align the external imaging device with the camera. For example, if the external imaging device is not aligned with the camera on the first installation, both the external imaging device and the adapter need to be removed and reinstalled. Alternatively, the adapter may need to be repeatedly rotated to align the external imaging device with the camera. This rotation or repeated disassembly and reassembly process risks damaging the adapter or housing and results in a poor user experience.

[0072] Based on this, embodiments of this application provide an electronic device that can avoid users having to repeatedly disassemble or rotate the device to align the lens mounting part and the camera, thereby reducing the failure rate of the electronic device and providing users with a better user experience.

[0073] This application provides an electronic device. The electronic device can be referred to as a user equipment (UE) or terminal, etc. For example, the electronic device can be a portable Android device (PAD), a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device, an in-vehicle device, a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. This application does not specifically limit the form of the electronic device.

Figure 2 This is an exploded view of the electronic device provided in the embodiments of this application. Figure 3 This is a structural schematic diagram of the electronic device provided in an embodiment of this application from another angle.

[0075] See Figures 1 to 3 As shown, the example given is an electronic device 10 that is a handheld device with wireless communication capabilities. For example, a handheld device with wireless communication capabilities could be a mobile phone.

[0076] Electronic device 10 includes housing 100 and display module 200, wherein, Figure 1 The image shows one side of the display module 200 of the electronic device 10.

[0077] The display module 200 can be an organic light-emitting diode (OLED) display screen. The display module 200 can also be a micro organic light-emitting diode (micro OLED) display screen, or a micro organic light-emitting diode (micro OLED) display screen, etc.

[0078] See Figure 1 and Figure 2 As shown, the housing 100 includes a middle frame 110 and a back cover 120. The middle frame 110 includes a middle plate 111 and a side frame 112 connected to each other. The side frame 112 can be a rectangular frame, surrounding and connecting to the peripheral edge of the middle plate 111. The display module 200 can be mounted on the side frame 112. A lanyard mounting portion 1121 can be provided on the side frame 112, which has a lanyard hole 1122 through which a lanyard can pass to connect to the housing 100 for carrying the electronic device 10. Figure 1 and Figure 2 The hanging rope installation part 1121 is not shown in the figure.

[0079] See also Figure 2 and Figure 3 The housing 100 may also include a rear cover 120. The rear cover 120 covers the side of the middle frame 110 opposite to the display module 200 and is connected to the frame 112. The rear cover 120 may also form a cavity with the middle frame 110, in which components such as the circuit board 300 or a battery may be housed.

[0080] Electronic devices can be mounted on the circuit board 300. For example, electronic devices may include processor modules, system-on-chip (SoC), storage modules, communication modules, radio frequency modules, charging management modules, power management ICs (PMICs), etc.

[0081] The processor module on circuit board 300 can be connected to display module 200 to control the display brightness of display module 200, reducing power consumption. It can also adjust the display brightness of display module 200 according to the intensity of ambient light outside electronic device 10, enabling display module 200 to achieve better display effects and improve user experience. A battery is used to power the display module.

[0082] The electronic device 10 also includes a camera module 400, which is also located in the cavity formed by the back cover 120 and the middle frame 110, and the camera module 400 is electrically connected to the circuit board 300.

[0083] Figure 4 An exploded view of the back cover and adapter of the electronic device housing provided in this application embodiment. Figure 1 , Figure 5 A schematic diagram of the structure of the adapter in the electronic device provided in the embodiments of this application. Figure 1 , Figure 6 An exploded view of the back cover and adapter of the electronic device housing provided in this application embodiment. Figure 2 , Figure 7 A schematic diagram of the structure of the housing in the electronic device provided in the embodiments of this application. Figure 1 , Figure 8 A schematic diagram of the structure of the adapter in the electronic device provided in the embodiments of this application. Figure 2 Among them, in Figure 4 The image accessories that are installed in conjunction with the adapter 500 are also shown.

[0084] The housing 100 of the electronic device 10 includes a first mounting portion 130, which has a through hole 131; a camera module 400 is opposite to the through hole 131, and the camera module 400 includes at least one camera 410; the electronic device 10 also includes an adapter 500, which has a second mounting portion 510 on the side facing the housing 100, and the second mounting portion 510 is used to connect with the first mounting portion 130; the adapter 500 has at least one lens mounting portion 520 on the side away from the housing 100, and the lens mounting portion 520 is used to mount an external imaging accessory; a first positioning portion 140 is provided on one of the adapter 500 and the housing 100, and a second positioning portion 530 is provided on the other; the first positioning portion 140 and the second positioning portion 530 are engaged so that the lens mounting portion 520 is opposite to the camera 410.

[0085] Specifically, the first mounting part 130 can be disposed on the rear cover 120. The first mounting part 130 can be annular, and has a through hole 131. The through hole 131 can be circular or rectangular. Figure 4 , Figure 6 and Figure 7 In the image, the through-hole 131 is rectangular. The camera module 400 is aligned with the through-hole 131 along the axial direction L, so that light from the external environment can enter the camera module 400 through the through-hole 131. Figure 4 In the diagram, with the center of the first mounting portion 130 as the axis, the axial direction L, circumferential direction C, and radial direction R of the first mounting portion 130 are shown. The first mounting portion 130 can be integrally formed with the rear cover 120 (e.g., Figure 3 and Figure 4 As shown), the first mounting part 130 can also be connected to the rear cover 120 by fasteners (e.g., as shown). Figure 6 and Figure 7 (As shown).

[0086] Please continue reading Figure 2 As shown, the camera module 400 is provided with a camera mounting position 420. The camera module 400 may include one camera mounting position 420, or it may include two or more camera mounting positions 420. For example, in Figure 2 The image shows four mounting positions 420 for cameras 410, with cameras 410 installed in two of the positions. The other two camera mounting positions 420 are reserved for future camera installations, allowing for the addition of more cameras 410 if needed.

[0087] When the camera 410 does not meet the user's needs, such as when the resolution or focal length of the camera 410 does not meet the user's needs, an external lens 20 or image accessories such as filters can be connected to the electronic device 10. Figure 4 In the image accessory shown, an external lens 20 is depicted. In this embodiment, the external lens 20 can be connected via an adapter 500.

[0088] The adapter 500 has a second mounting portion 510 on the side facing the housing 100. The second mounting portion 510 matches the first mounting portion 130. For example, the second mounting portion 510 has a mounting protrusion on the side facing the housing 100, and the first mounting portion 130 has a slot. The protrusion engages with the slot to connect the adapter 500 to the housing 100.

[0089] The adapter 500 has a lens mounting portion 520 on the side opposite to the housing 100, on which an external lens 20 can be mounted. The external lens 20 needs to be aligned with the camera 410 to improve the shooting effect of the camera 410 aligned with the external lens 20. Therefore, the lens mounting portion 520 needs to be aligned with the camera 410 one by one.

[0090] In this embodiment, a first positioning part 140 and a second positioning part 530 are provided to facilitate the alignment of the lens mounting part 520 with the camera 410.

[0091] Specifically, the first positioning part 140 can be disposed on the housing 100, or the first positioning part 140 can be disposed on the adapter 500. Figure 4 , Figure 6 and Figure 7 In this configuration, the first positioning part 140 is disposed on the first mounting part 130 of the housing 100. The second positioning part 530 may be disposed on the housing 100 or on the adapter 500. Figure 5 and Figure 8 In the middle, the second positioning part 530 is provided on the second mounting part 510 of the adapter 500.

[0092] When installing the adapter 500 to the housing 100, the adapter 500 is brought close to the housing 100, and the first mounting part 130 and the second mounting part 510 are prepared to connect. Then, the adapter 500 is rotated circumferentially C relative to the housing 100 until the first positioning part 140 and the second positioning part 530 engage. When the first positioning part 140 and the second positioning part 530 engage, the first mounting part 130 and the second mounting part 510 are connected. Through the first positioning part 140 and the second positioning part 530, the user can feel the engagement of the first positioning part 140 and the second positioning part 530 when installing the adapter 500. This stops the rotation of the adapter 500, avoiding the user having to repeatedly disassemble or rotate it to align the lens mounting part 520 and the camera 410, reducing the failure rate of electronic devices and providing a better user experience. Furthermore, when installing the adapter 500, the user only needs to rotate the adapter 500 a certain angle relative to the housing 100, and the first positioning part 140 and the second positioning part 530 will engage during the rotation of the adapter 500 relative to the housing 100. In other words, the user only needs to rotate the adapter 500, without needing to spend time familiarizing themselves with the engagement method of the first positioning part 140 and the second positioning part 530, thereby reducing the time required for the user to learn the engagement method.

[0093] The specific connection method between the adapter 500 and the housing 100 will be described below.

[0094] A first mounting protrusion 132 is provided on one of the first mounting portion 130 and the second mounting portion 510, and a first mounting groove 511 corresponding to the first mounting protrusion 132 is provided on the other. The first mounting groove 511 includes a first engaging section 512 and a first limiting section 513. At the first position, the first mounting protrusion 132 is aligned with the first engaging section 512 to enter the first engaging section 512. When the adapter 500 rotates relative to the housing 100 in the circumferential direction C to the second position, the first mounting protrusion 132 engages with the first limiting section 513, and the first positioning portion 140 engages with the second positioning portion 530.

[0095] exist Figure 4 and Figure 5 In this case, the outer diameter of the first mounting part 130 is smaller than the inner diameter of the second mounting part 510. Therefore, the second mounting part 510 is fitted onto the first mounting part 130. At this time, the first mounting protrusion 132 is provided on the first mounting part 130, and the first mounting groove 511 is provided on the second mounting part 510.

[0096] exist Figures 6 to 8 In this case, the inner diameter of the first mounting part 130 is larger than the outer diameter of the second mounting part 510. Therefore, the first mounting part 130 is fitted onto the second mounting part 510. At this time, the first mounting protrusion 132 is provided on the second mounting part 510, and the first mounting groove 511 is provided on the first mounting part 130.

[0097] Below, with Figure 4 and Figure 5 Taking the embodiment in the text as an example, the connection method between the adapter 500 and the housing 100 will be described.

[0098] The first position is the alignment of the first mounting protrusion 132 and the first snap-in section 512 in the adapter 500, which is the position where the adapter 500 and the housing 100 are ready to be connected. The second position is the position where the first positioning part 140 and the second positioning part 530 snap together after the adapter 500 is rotated relative to the housing 100 in the circumferential direction C.

Figure 3 .in, Figures 9a to 9cThe diagram shows the structure of the adapter 500 facing the housing 100, and the adapter 500 is mirrored to clearly show the relative positional changes of the first mounting groove 511 and the first mounting protrusion 132. Furthermore, in Figures 9a to 9c The specific position boundary of the first limiting segment 513 away from the first inserting segment 512 is also shown by a dashed line.

[0100] See Figure 5 , Figures 9a to 9c As shown, the first insertion section 512 includes an opening 5121 and a first slot 5122 communicating with the opening 5121, and the first limiting section 513 includes a second slot 5131 and a limiting wall 5132, with the second slot 5131 communicating with the first slot 5122; in the first position, the first mounting protrusion 132 enters the first slot 5122 through the opening 5121; in the second position, the first mounting protrusion 132 enters the second slot 5131 and engages with the limiting wall 5132.

[0101] The first mounting protrusion 132 is a protrusion that extends radially R on the first mounting portion 130. The first mounting protrusion 132 can be a protrusion segment extending circumferentially C. The first engaging section 512 includes an open opening 5121 and a first engaging groove 5122 communicating with the opening 5121. The first limiting section 513 includes a limiting wall 5132, which can also be a limiting wall extending circumferentially C. The position aligned with the limiting wall 5132 along the axial direction L is the second engaging groove 5131.

[0102] The length of the opening 5121 and the first slot 5122 along the circumferential direction C is greater than or equal to the length of the first mounting protrusion 132 along the circumferential direction C. Please continue to the next section. Figure 9a As shown, when installing the adapter 500 onto the housing 100, the first mounting protrusion 132 is aligned with the opening 5121, and the first mounting protrusion 132 enters the first slot 5122 through the opening 5121. Please continue to see... Figure 9b As shown, the adapter 500 rotates relative to the housing 100. With the rotation of the adapter 500, the first mounting protrusion 132 gradually moves from the first slot 5122 of the first engaging section 512 into the second slot 5131 of the first limiting section 513. Please continue to the next section. Figure 9c As shown, the first mounting protrusion 132 is completely located in the second slot 5131, and the limiting wall 5132 limits the first mounting protrusion 132 along the axial direction L, allowing the adapter 500 to be installed onto the housing 100. When disassembling the adapter 500, rotate the adapter 500 so that the first mounting protrusion 132 changes from the position aligned with the second slot 5131 to the position aligned with the first slot 5122, and then remove the first mounting protrusion 132 from the opening 5121.

[0103] Therefore, when installing the adapter 500, aligning the first mounting protrusion 132 with the first snap-in section 512 can serve as a pre-alignment for the adapter 500. When disassembling the adapter 500, simply rotate the adapter 500 until the first mounting protrusion 132 and the first snap-in section 512 are aligned. This further reduces the number of times the user needs to rotate the adapter 500.

[0104] In related technologies, a button and a first connector are provided on the housing, and a second connector is provided on the adapter. The button is connected to the first connector. The first connector is connected to the second connector to connect the adapter to the housing. When the adapter needs to be disassembled, the button needs to be pressed to disconnect the connection between the first connector and the second connector. The button increases the thickness of the housing, and space needs to be provided along the thickness direction for the button to move, further increasing the thickness of the electronic device. Moreover, the connection structure between the button and the first connector is relatively complex, making the disassembly of the adapter relatively complicated. In the electronic device provided in this application embodiment, since the first mounting protrusion 132 is a protrusion extending along the circumferential direction C, and the limiting wall 5132 is also a limiting wall extending along the circumferential direction C, when the adapter 500 rotates relative to the housing 100 until the first mounting protrusion 132 enters the second slot 5131, the limiting wall 5132 can limit the first mounting protrusion 132. Both the limiting wall 5132 and the first mounting protrusion 132 extend along the circumferential direction C. Therefore, it is possible to avoid increasing the size of the electronic device 10 along the thickness direction (i.e., the axial direction L). Furthermore, the adapter 500 can be removed from the housing 100 by rotating the adapter 500. Compared to the related art, which requires pressing a button and then rotating the adapter, the method of removing the adapter 500 is simpler.

[0105] In one possible implementation, there are at least two first mounting slots 511, and the at least two first mounting slots 511 are spaced apart along the circumferential direction C; the first mounting protrusions 132 are provided in a one-to-one correspondence with the first mounting slots 511.

[0106] When a first mounting slot 511 and a first mounting protrusion 132 that matches the first mounting slot 511 are provided, the adapter 500 can easily detach from the housing 100.

[0107] Therefore, two or more first mounting slots 511 can be provided on the second mounting part 510. Figure 5The diagram schematically shows three first mounting slots 511, which are spaced apart circumferentially C. The first mounting portion 130 has three first mounting protrusions 132 corresponding to each of the first mounting slots 511. In a first position, the three first mounting protrusions 132 are aligned with the openings 5121 in the three first mounting slots 511 to further improve alignment. In a second position, the limiting walls 5132 in the three first mounting slots 511 engage with the three first mounting protrusions 132, making the connection between the adapter 500 and the housing 100 more reliable.

[0108] In one possible implementation, the axial dimension of the first mounting protrusion 132 and the axial dimension of the second slot 5131 are configured such that the first mounting protrusion 132 and the second slot 5131 are in clearance fit.

[0109] Therefore, when the adapter 500 rotates relative to the housing 100 until the first mounting protrusion 132 is located in the second slot 5131, the resistance to the rotation of the adapter 500 is small.

[0110] The following describes one embodiment of the first positioning unit 140 and the second positioning unit 530.

[0111] Please continue reading Figure 4 , Figure 5 , Figures 9a to 9c As shown, the first positioning part 140 is a positioning protrusion 141 protruding along the axial direction L, and the second positioning part 530 is an elongated hole 531 corresponding to the positioning protrusion 141. The elongated hole 531 extends along the circumferential direction C, and the size of the elongated hole 531 along the circumferential direction C is larger than the size of the positioning protrusion 141 along the circumferential direction C. The elongated hole 531 includes a first end 5311 and a second end 5312 arranged along the circumferential direction C. At the first position, the positioning protrusion 141 is aligned with the first end 5311 of the elongated hole 531 and is inserted into the elongated hole 531 at the first end 5311. When the adapter 500 rotates relative to the housing 100 to the second position, the positioning protrusion 141 rotates relative to the elongated hole 531 to the second end 5312.

[0112] Specifically, the first positioning part 140 can be a positioning protrusion 141 provided on the first mounting part 130, and the positioning protrusion 141 protrudes from the side of the first mounting part 130 toward the adapter 500. An elongated hole 531 is formed on the second mounting part 510, and the elongated hole 531 is an arc-shaped elongated hole extending along the circumferential direction C. The dimension of the positioning protrusion 141 along the circumferential direction C is a first dimension C1, and the dimension of the elongated hole 531 along the circumferential direction C is a second dimension C2, where the second dimension C2 is larger than the first dimension C1.

[0113] Please continue reading Figure 9aAs shown, in the first position, that is, when the first mounting protrusion 132 is aligned with the first inserting section 512, the positioning protrusion 141 is aligned with the first end 5311 of the elongated hole 531 and inserted into the elongated hole 531 at the first end 5311.

[0114] Please continue reading Figure 9c As shown, when the adapter 500 rotates relative to the housing 100 to the second position, that is, when the first mounting protrusion 132 rotates to the first limiting section 513, the positioning protrusion 141 rotates relative to the elongated hole 531 to the second end 5312. At this time, the positioning protrusion 141 abuts against the end of the second end 5312. This prevents the adapter 500 from continuing to rotate relative to the housing 100.

[0115] By cooperating with the positioning protrusion 141 and the elongated hole 531, the adapter 500 can be positioned without affecting its rotation relative to the housing 100.

[0116] Next, another embodiment of the first positioning unit 140 and the second positioning unit 530 will be described.

[0117] Figure 10 For along Figure 3 Sectional view of plane AA. Figure 11 for Figure 10 Enlarged view of point B in the middle.

[0118] See Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown, the first positioning part 140 is an elastic component 142 protruding along the axial direction L; the second positioning part 530 is a positioning groove 532 recessed along the axial direction L; at the second position, the elastic component 142 and the positioning groove 532 elastically abut against each other.

[0119] Specifically, the elastic component 142 can protrude axially L from the first mounting portion 130, in which case the positioning groove 532 is a positioning groove 532 recessed from the second mounting portion 510. Alternatively, the elastic component 142 can protrude axially L from the second mounting portion 510, in which case the positioning groove 532 is a positioning groove 532 recessed from the first mounting portion 130. Figure 10 In the embodiment shown, the elastic component 142 can protrude from the first mounting portion 130 along the axial direction L. In this case, the positioning groove 532 is a positioning groove 532 recessed from the second mounting portion 510.

[0120] The elastic component 142 has an axial force direction of L. At the first position, the elastic component 142 abuts against the second mounting portion 510 under the action of the elastic force. The adapter 500 experiences significant resistance to rotation relative to the housing 100. As the adapter 500 rotates to the second position, the elastic component 142 enters the positioning groove 532 under the action of the elastic force. The user will suddenly feel a decrease in resistance. Furthermore, the elastic component 142 will emit a beeping sound when entering the positioning groove 532 due to the elastic force. Therefore, the user can determine that the adapter 500 is properly installed based on the decrease in resistance and the beeping sound, resulting in a better user experience.

[0121] Figure 12 for Figure 11 A schematic diagram of the structure of the elastic component and the mounting hole.

[0122] See Figure 12 As shown, the elastic component 142 includes an elastic element 1421 and a ball bearing 1422; the first positioning part 140 also includes a limiting post 143, which has a mounting hole 1431 extending along the axial direction L. The elastic element 1421 and the ball bearing 1422 are both located in the mounting hole 1431, with the ball bearing 1422 facing the positioning groove 532; under the elastic force of the elastic element 1421, the ball bearing 1422 abuts against the inner wall of the positioning groove 532.

[0123] The limiting post 143 extends from the first positioning part 140 toward the adapter 500. The limiting post 143 is a hollow column with a mounting hole 1431 extending along the axial direction L. The elastic element 1421 can be a coil spring, an elastic sleeve, or other elastic components. One end of the elastic element 1421 is connected to the bottom wall of the mounting hole 1431, and the other end of the elastic element 1421 abuts against the ball 1422.

[0124] When the adapter 500 rotates relative to the housing 100, the ball 1422 can roll along with the rotation of the adapter 500, thereby reducing the wear on the ball 1422 and improving the service life of the first positioning part 140 and the second positioning part 530.

[0125] Please continue reading Figure 12 As shown, the diameter of the end of the mounting hole 1431 facing the positioning groove 532 is smaller than the diameter of the ball 1422, so as to limit the ball 1422 within the mounting hole 1431.

[0126] The mounting hole 1431 includes a mounting section 1431a and a limiting section 1431b. The limiting section 1431b faces the adapter 500. The diameter of the ball 1422 is a first diameter D1. The mounting section 1431a and the ball 1422 can be clearance-fitted to allow the ball 1422 to move within the mounting section 1431a. The diameter of the limiting section 1431b is a second diameter D2, which is smaller than the first diameter D1. This prevents the ball 1422 from dislodging from the mounting hole 1431.

[0127] Figure 13 A schematic diagram of the structure of the housing in the electronic device provided in the embodiments of this application. Figure 2 , Figure 14 for Figure 13 Enlarged view at point C in the middle. Figure 15 A schematic diagram of the structure of the adapter in the electronic device provided in the embodiments of this application. Figure 3 , Figure 16 for Figure 15 Enlarged view of point D in the middle.

[0128] See Figures 13 to 16 As shown, the electronic device 10 also includes a limiting component 600, which includes a limiting protrusion 610 and a limiting groove 620. The limiting protrusion 610 and the first mounting protrusion 132 are both located on the first mounting portion 130 and protrude radially R from the first mounting portion 130. The limiting groove 620 is located on the limiting wall 5132 and is recessed radially R from the end face of the limiting wall 5132. When the adapter 500 rotates relative to the housing 100 to the second position, the limiting protrusion 610 is located in the limiting groove 620.

[0129] Specifically, the limiting protrusion 610 is a protrusion that extends outward along the radial direction R from the first mounting portion 130. The limiting groove 620 is provided on the limiting wall 5132, that is, the limiting groove 620 is offset from the first mounting protrusion 132 along the axial direction L, so that the limiting groove 620 will not interfere with the first mounting protrusion 132.

[0130] Figure 17a This application provides a schematic diagram of the process of installing the adapter and housing in an electronic device. Figure 4 , Figure 17b This application provides a schematic diagram of the process of installing the adapter and housing in an electronic device. Figure 5 , Figure 17c This application provides a schematic diagram of the process of installing the adapter and housing in an electronic device. Figure 6 .

[0131] See Figure 17a As shown, in the first position, the limiting groove 620 and the limiting protrusion 610 are offset along the circumferential direction C. See also Figure 17bAs shown, as the adapter 500 moves along the circumferential direction C relative to the housing 100, the limiting protrusion 610 first contacts the side of the limiting wall 5132 facing the first locking section 512. At this time, the limiting protrusion 610 applies resistance to the rotation of the adapter 500, and the user will feel this resistance during the rotation of the adapter 500. See also Figure 17c As shown, when the adapter 500 continues to rotate along the circumferential direction C to the second position, the limiting protrusion 610 will enter the limiting groove 620. At this time, the user will feel a sudden decrease in resistance. This sudden decrease in resistance will give the user a prompt that the adapter 500 is installed in place. Thus, the user can have a better user experience when installing the adapter 500.

[0132] Please continue reading Figure 14 and Figure 16 As shown, the limiting protrusion 610 and the first mounting protrusion 132 are spaced apart along the circumferential direction C on the first mounting portion 130; the first mounting protrusion 132 has a first sidewall 1321 facing the limiting protrusion 610 and a second sidewall 1322 facing away from the limiting protrusion 610, and the distance between the second sidewall 1322 and the limiting protrusion 610 along the circumferential direction C is less than or equal to the dimension of the first inserting segment 512 along the circumferential direction C.

[0133] The first mounting protrusion 132 has a first sidewall 1321 and a second sidewall 1322 along both sides of the circumferential direction C. The limiting protrusion 610 can be disposed on one side of the first sidewall 1321 and the second sidewall 1322. Figure 14 In the illustrated embodiment, the limiting protrusion 610 is disposed on one side of the first sidewall 1321. That is, the distance between the limiting protrusion 610 and the second sidewall 1322 is greater than the distance between the limiting protrusion 610 and the first sidewall 1321.

[0134] The limiting protrusion 610 has a distance of C3 along the circumferential direction from the second sidewall 1322, which is a third dimension. The first inserting section 512 has a distance of C4 along the circumferential direction, which is a fourth dimension. The fourth dimension C4 is greater than or equal to the third dimension C3. At the first position, both the limiting protrusion 610 and the first mounting protrusion 132 enter the first slot 5122 from the opening 5121 of the first inserting section 512. This avoids interference between the limiting wall 5132 and the limiting protrusion 610 at the first position.

[0135] In one possible implementation, the dimension of the limiting protrusion 610 along the axial direction L is greater than or equal to the dimension of the limiting wall 5132 along the axial direction.

[0136] The larger the contact area between the limiting protrusion 610 and the limiting wall 5132, the greater the resistance that the limiting protrusion 610 will exert on the rotation of the adapter 500. During the rotation, the user will feel the resistance more obviously. When the limiting protrusion 610 enters the limiting groove 620, the resistance will decrease more obviously, and the user's experience will be better.

[0137] The dimension of the limiting wall 5132 along the axial direction L is the fifth dimension L1, the dimension of the limiting protrusion 610 along the axial direction L is the sixth dimension L2, and the dimension of the limiting groove 620 along the axial direction L is determined by the fifth dimension L1. Therefore, the dimension of the limiting groove 620 along the axial direction L is difficult to change. Thus, the sixth dimension L2 of the limiting protrusion 610 can be increased, making it greater than or equal to the fifth dimension L1. This increases the contact area between the limiting protrusion 610 and the limiting wall 5132, increasing the resistance exerted by the limiting protrusion 610 on the rotation of the adapter 500. During rotation, the user experiences increased resistance, and the reduction in resistance becomes more pronounced when the limiting protrusion 610 enters the limiting groove 620, further enhancing the user experience.

[0138] Please continue to reduce. Figure 16 As shown, the end of the limiting wall 5132 facing the first engaging section 512 is provided with a rounded corner 5132a. By providing the rounded corner 5132a, the resistance is small when the limiting protrusion 610 first contacts the limiting wall 5132, and the resistance gradually increases as the adapter 500 rotates further. A sudden increase in resistance may cause the user to mistakenly believe that the adapter 500 is stuck or that other installation malfunctions have occurred. Therefore, providing the rounded corner 5132a at the end of the limiting wall 5132 facing the first engaging section 512 can reduce the probability of user misjudgment and further improve the user experience.

[0139] Please continue reading Figure 16 As shown, the first mounting groove 511 has a third sidewall 514 opposite to the second sidewall 1322, and at the second position, the third sidewall 514 abuts against the second sidewall 1322.

[0140] A third sidewall 514 can also be provided on the side of the first mounting groove 511 opposite to the first snap-in section 512. When the adapter 500 rotates to the second position relative to the housing 100, the second sidewall 1322 can also abut against the third sidewall 514. Thus, the adapter 500 is limited by the abutment between the second sidewall 1322 and the third sidewall 514 and the snap-in between the first positioning part 140 and the second positioning part 530. This can better limit the adapter 500. If either the abutment between the second sidewall 1322 and the third sidewall 514 or the snap-in between the first positioning part 140 and the second positioning part 530 fails, the adapter 500 can still be ensured to stop rotating in the second position, which can further improve the user experience.

[0141] Figure 18 A schematic diagram of the structure of the adapter in the electronic device provided in the embodiments of this application. Figure 4 .

[0142] See Figure 18 As shown, the adapter 500 is provided with a first clearance hole 540, and the electronic device 10 also includes a signal transmitting device (not shown in the figure). At the second position, the first clearance hole 540 corresponds to the position of the signal transmitting device.

[0143] Specifically, the signal transmitting device can be an antenna or a WiFi module. When the adapter 500 is installed on the housing 100, the position of the first clearance hole 540 can be aligned with the position of the signal transmitting device, thereby preventing the adapter 500 from interfering with the signal transmission of the electronic device 10. There can be one, two, or more signal transmitting devices.

[0144] Please continue to participate. Figure 18 As shown, the adapter 500 is provided with a second clearance hole 550, and the camera module 400 also includes a flash (not shown in the figure). At a second position, the second clearance hole 550 is aligned with the flash. This prevents the adapter 500 from blocking the flash light, thereby improving the shooting effect.

[0145] The following describes the specific connection method between the external lens 20 and the adapter 500.

[0146] Please continue reading Figure 18 As shown, the lens mounting part 520 includes a second mounting groove 521, which includes a second snap-in section 5211 and a second limiting section 5212. The second mounting groove 521 is configured to mount a second mounting protrusion (not shown) in an external imaging accessory, so that the second mounting protrusion enters the second mounting groove 521 from the second snap-in section 5211 and the second mounting protrusion can rotate relative to the second mounting groove 521 until the second mounting protrusion engages with the second limiting section 5212.

[0147] The second mounting protrusion can be located on the side of the external lens 20 facing the adapter 500. The second locking section 5211 can have the same structure as the first locking section 512, and the second limiting section 5212 can have the same structure as the first limiting section 513. Therefore, the installation process of the second mounting protrusion and the second mounting groove 521 is the same, and will not be described in detail here. Two or more second mounting grooves 521 can also be provided to prevent the external lens 20 from falling off the lens mounting part 520.
