Description

Technical Field

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

[0002] The camera function is already an indispensable function for electronic devices (such as mobile phones, tablets, etc.). A camera hole can be opened on the display screen of the electronic device so that the camera device can receive light through the camera hole.

[0003] In related technologies, the camera device can be configured as a lift-up structure. When shooting, the entire camera device is driven to extend from the side wall of the electronic device, thereby avoiding the need to open a camera hole on the display screen, thus increasing the screen-to-body ratio and reducing the impact on the display effect.

[0004] However, the image quality of the aforementioned camera device needs improvement. Summary of the Invention

[0005] This application provides a lifting device, a camera device, and an electronic device, which can improve the imaging quality of the camera device and the electronic device.

[0006] A first aspect of this application provides a lifting device, including: a carrier, a rotating member, a lifting member, a first magnetic induction sensor, and a first magnetic element. The rotating member is rotatably mounted on the carrier, and the rotating member and the lifting member cooperate with each other. The rotating member is used to drive the lifting member to move up and down during rotation. One of the first magnetic induction sensor and the first magnetic element is connected to the rotating member, and the other of the first magnetic induction sensor and the first magnetic element is connected to the carrier. The first magnetic element is used to generate a first magnetic field, and the first magnetic induction sensor is located in the first magnetic field. The rotating member is used to drive one of the first magnetic induction sensor and the first magnetic element to move closer to or away from the other during rotation.

[0007] The lifting device provided in this application embodiment may include a support member, a rotating member, a lifting member, a first magnetic induction sensor, and a first magnetic element. The rotating member is rotatably mounted on the support member, and the rotating member and the lifting member cooperate with each other. The rotating member is used to drive the lifting member to rise and fall during rotation. Because the volume between the lifting member and the rotating member along the thickness direction of the lifting device increases after the lifting member rises relative to the rotating member, the volume of the lifting device along the thickness direction increases, thereby increasing the volume of the camera device with the camera module, thus increasing the overall length of the camera lens and improving the imaging quality of the camera device and electronic equipment. Conversely, the volume of the lifting device decreases after the lifting member descends, thereby reducing the impact of the lifting device on the volume of the camera device and electronic equipment. One of the first magnetic induction sensor and the first magnetic element is connected to the rotating member, and the other of the first magnetic induction sensor and the first magnetic element is connected to the support member. The first magnetic element generates a first magnetic field, and the first magnetic induction sensor is located in the first magnetic field and senses the strength of the first magnetic field. The rotating member is used to move one of the first magnetic induction sensor and the first magnetic element closer to or away from the other during rotation. When the first magnetic induction sensor is close to the first magnetic component, the intensity of the first magnetic field it senses is higher; when the first magnetic induction sensor is far from the first magnetic component, the intensity of the first magnetic field it senses is lower. The first magnetic induction sensor senses the intensity of the first magnetic field and generates a corresponding electrical signal. Based on this electrical signal, it determines the rotation angle of the rotating component, thereby determining whether the rotating component has rotated to its correct position (or is jammed), and thus whether the lifting device has raised or lowered to its correct position. If the camera device has not raised or lowered to its correct position, the rotation of the rotating component can be further controlled to ensure that it rotates to its correct position, thereby ensuring that the lifting device and camera device are raised or lowered to their correct positions, thus avoiding any impact on the imaging quality and lifespan of the camera device.

[0008] In one possible implementation, there are two first magnetic elements, which are spaced apart circumferentially along the rotating member. The rotating member is used to drive the first magnetic induction sensor to move closer to one of the two first magnetic elements and further away from the other of the two first magnetic elements during rotation.

[0009] In this way, the first magnetic field of the two first magnetic components covers a large area along the circumference of the rotating component. During the rotation of the rotating component, the first magnetic induction sensor can be located in the first magnetic field, thus effectively measuring the rotation angle of the rotating component. In addition, the total extension length and bending angle of the two first magnetic components can be set to be small, which helps to reduce the cost and installation difficulty of the first magnetic components.

[0010] In one possible implementation, the south-to-north pole directions of the two first magnetic elements are arranged oppositely along the axial direction of the rotating element; or, the south-to-north pole directions of the two first magnetic elements are both the same as the circumferential direction of the rotating element.

[0011] In this way, there are many ways to set up the two first magnetic components, which can be applied to a wide range of scenarios.

[0012] In one possible implementation, the carrier includes a connected carrier base and a carrier circuit board, and the rotating component is rotatably mounted on the carrier base.

[0013] In one possible implementation, the carrier circuit board includes a first carrier circuit board, a first magnetic induction sensor connected to the first carrier circuit board, and a first magnetic element connected to the rotating element.

[0014] In this way, when the first magnetic induction sensor is connected to the support member, it can be avoided that when the first magnetic induction sensor is connected to the rotating member, the structural member used for connecting to the control member will be pulled during rotation.

[0015] In one possible implementation, the lifting device further includes a first magnetic isolator, with the first magnetic induction sensor located on the side of the first carrier circuit board facing the first magnetic element, and the first magnetic isolator located on the side of the first carrier circuit board away from the first magnetic element.

[0016] In this way, the first magnetic isolator is used to reduce the interference of the external magnetic field on the first magnetic induction sensor.

[0017] In one possible implementation, the lifting device includes a second magnetic induction sensor and a second magnetic element, one of which is connected to the lifting member, and the other of which is connected to the bearing member; the second magnetic element is used to generate a second magnetic field, the second magnetic induction sensor is located in the second magnetic field, and the lifting member is used to move one of the second magnetic induction sensor and the second magnetic element closer to or away from the other during the lifting process.

[0018] In this way, the second magnetic induction sensor and the second magnetic component, together with the control component, can be used to determine whether the lifting component has reached the correct position or if it is jammed.

[0019] In one possible implementation, the carrier circuit board includes a second carrier circuit board, a second magnetic induction sensor is connected to the second carrier circuit board, and a second magnetic element is connected to the lifting element.

[0020] In this way, when the second magnetic induction sensor is connected to the support member, it can avoid the structural member used for connecting to the control member being pulled during rotation when the second magnetic induction sensor is connected to the rotating member.

[0021] In one possible implementation, the lifting device further includes a second magnetic isolator, with the second magnetic sensor located on the side of the second carrier circuit board facing the second magnetic component, and the second magnetic isolator located on the side of the second carrier circuit board away from the second magnetic component.

[0022] In this way, the second magnetic isolator is used to reduce the interference of external magnetic fields on the second magnetic induction sensor.

[0023] In one possible implementation, a guide is provided on one of the rotating and lifting components, and a guide channel is provided on the other of the rotating and lifting components. The guide channel is inclined relative to the lifting direction of the lifting component. A protrusion is provided on the guide, which is inserted into the guide channel and reciprocates along the extension direction of the guide channel.

[0024] In this way, the structure of the guide component and guide channel is relatively simple.

[0025] In one possible implementation, along the lifting direction of the lifting member, the inner wall surface of the guide channel includes a first driving surface and a second driving surface that are opposite to and spaced apart, and a protrusion is located between the first driving surface and the second driving surface; at least one of the first driving surface and the second driving surface is a plane; or, at least one of the first driving surface and the second driving surface is a curved surface that bends toward the descending direction of the lifting member.

[0026] In this way, when the driving surface has a variety of shapes, it can be applied to a wide range of scenarios.

[0027] In one possible implementation, the lifting device includes a driving member, which includes a driving member body and a driving shaft. The driving shaft is rotatably connected to the driving member body and includes a first shaft end and a second shaft end opposite to each other. The first shaft end cooperates with the rotating member.

[0028] In one possible implementation, the drive component further includes an anti-slip member, which includes a connected elastic part and a fixed part. The fixed part is connected to the side of the drive component body away from the first shaft end, and the elastic part abuts against the second shaft end.

[0029] In this way, the elastic part applies an elastic force to the second shaft end, thereby alleviating the axial movement of the drive shaft along the worm gear and preventing the drive shaft from squeezing the internal structural components of the drive unit body and causing jamming. In addition, the anti-axial movement component also protects the second shaft end.

[0030] In one possible implementation, the lifting device further includes a worm gear, with a first shaft end inserted into the worm gear along its axial direction; the first shaft end is interference-fitted with the worm gear, or the first shaft end is welded to the worm gear, or the first shaft end and the worm gear are integral parts.

[0031] In this way, there are many ways to connect the worm gear to the first shaft end, making it suitable for a wide range of scenarios.

[0032] A second aspect of this application provides a camera device, including a camera module and the lifting device described in the first aspect, wherein the camera module is connected to the lifting device.

[0033] The camera device provided in this application embodiment may include a lifting device, which may include a support member, a rotating member, a lifting member, a first magnetic induction sensor, and a first magnetic element. The rotating member is rotatably mounted on the support member, and the rotating member and the lifting member cooperate with each other. The rotating member is used to drive the lifting member to rise and fall during rotation. Because the volume between the lifting member and the rotating member along the thickness direction of the lifting device increases after the lifting member rises relative to the rotating member, the volume of the lifting device along the thickness direction increases, thereby increasing the volume of the camera device with the camera module, thus increasing the overall length of the camera lens and improving the imaging quality of the camera device and electronic equipment. Conversely, the volume of the lifting device decreases after the lifting member falls, thereby reducing the impact of the lifting device on the volume of the camera device and electronic equipment. One of the first magnetic induction sensor and the first magnetic element is connected to the rotating member, and the other of the first magnetic induction sensor and the first magnetic element is connected to the support member. The first magnetic element generates a first magnetic field, and the first magnetic induction sensor is located in the first magnetic field and senses the strength of the first magnetic field. The rotating member is used to move one of the first magnetic induction sensor and the first magnetic element closer to or further away from the other during rotation. When the first magnetic induction sensor is close to the first magnetic component, the intensity of the first magnetic field it senses is higher; when the first magnetic induction sensor is far from the first magnetic component, the intensity of the first magnetic field it senses is lower. The first magnetic induction sensor senses the intensity of the first magnetic field and generates a corresponding electrical signal. Based on this electrical signal, it determines the rotation angle of the rotating component, thereby determining whether the rotating component has rotated to its correct position (or is jammed), and thus whether the lifting device has raised or lowered to its correct position. If the camera device has not raised or lowered to its correct position, the rotation of the rotating component can be further controlled to ensure that it rotates to its correct position, thereby ensuring that the lifting device and camera device are raised or lowered to their correct positions, thus avoiding any impact on the imaging quality and lifespan of the camera device.

[0034] A third aspect of this application provides an electronic device including a housing and a camera device as described in the second aspect above, wherein the camera device is at least partially located within the housing.

[0035] The electronic device provided in this application embodiment may include a lifting device, which may include a support member, a rotating member, a lifting member, a first magnetic induction sensor, and a first magnetic element. The rotating member is rotatably mounted on the support member, and the rotating member and the lifting member cooperate with each other. The rotating member is used to drive the lifting member to rise and fall during rotation. Because the volume between the lifting member and the rotating member along the thickness direction of the lifting device increases after the lifting member rises relative to the rotating member, the volume of the lifting device along the thickness direction increases, thereby increasing the volume of the camera device with the camera module, thus increasing the overall length of the camera lens and improving the imaging quality of the camera device and the electronic device. Conversely, the volume of the lifting device decreases after the lifting member descends, thereby reducing the impact of the lifting device on the volume of the camera device and the electronic device. One of the first magnetic induction sensor and the first magnetic element is connected to the rotating member, and the other of the first magnetic induction sensor and the first magnetic element is connected to the support member. The first magnetic element generates a first magnetic field, and the first magnetic induction sensor is located in the first magnetic field and senses the strength of the first magnetic field. The rotating member is used to move one of the first magnetic induction sensor and the first magnetic element closer to or away from the other during rotation. When the first magnetic induction sensor is close to the first magnetic component, the intensity of the first magnetic field it senses is higher; when the first magnetic induction sensor is far from the first magnetic component, the intensity of the first magnetic field it senses is lower. The first magnetic induction sensor senses the intensity of the first magnetic field and generates a corresponding electrical signal. Based on this electrical signal, it determines the rotation angle of the rotating component, thereby determining whether the rotating component has rotated to the correct position or is jammed.

[0085] 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.

[0086] In related technologies, electronic devices may include a housing and a camera device, with the camera device located within the housing, which protects it. The camera device can be configured as a pop-up structure; during shooting, a drive component can extend the camera device from the side wall of the housing to the outside of the housing to allow light to enter the camera device. This avoids the need for a camera hole in the electronic device's display screen, thereby increasing the screen-to-body ratio and reducing the impact on the display's display quality.

[0087] However, because the camera device is located inside the housing, its thickness is relatively small to avoid affecting the housing's overall thickness. Therefore, the total length of the lens is short when the camera device is inside the housing. Furthermore, when the camera device rises, it extends entirely out of the housing. Since the thickness of the camera device remains unchanged after extending, the total length of the lens after extending is still short, resulting in poor image quality for both the camera device and the electronic device. Additionally, if the camera device does not rise to the required position, it may affect the camera device's lighting and optical path, thus impacting the image quality of both the camera device and the electronic device. If the camera device does not descend to the required position, the housing may not adequately protect the camera device, affecting its lifespan. Since it is impossible to determine whether the camera device has reached the correct position, it is impossible to further determine whether it is necessary to re-control the drive assembly to move the camera device up and down to the desired position.

[0088] Based on the above problems, this application provides a lifting device, a camera device, and an electronic device. The lifting device may include a support member, a rotating member, a lifting member, a first magnetic induction sensor, and a first magnetic element. The rotating member is rotatably mounted on the support member, and the rotating member and the lifting member cooperate with each other. The rotating member is used to drive the lifting member to rise and fall during rotation. Because the volume of the lifting member relative to the rotating member increases along the thickness direction of the lifting device after the lifting member rises, the volume of the lifting device along the thickness direction increases, thereby increasing the volume of the camera device with the camera module, thus increasing the overall length of the camera lens and improving the imaging quality of the camera device and the electronic device. Furthermore, the volume of the lifting device decreases after the lifting member falls, thereby reducing the impact of the lifting device on the volume of the camera device and the electronic device. One of the first magnetic induction sensor and the first magnetic element is connected to the rotating member, and the other of the first magnetic induction sensor and the first magnetic element is connected to the support member. The first magnetic element generates a first magnetic field, and the first magnetic induction sensor is located in the first magnetic field and senses the strength of the first magnetic field. The rotating member is used to move one of the first magnetic induction sensor and the first magnetic element closer to or away from the other during rotation. When the first magnetic induction sensor is close to the first magnetic component, the intensity of the first magnetic field it senses is higher; when the first magnetic induction sensor is far from the first magnetic component, the intensity of the first magnetic field it senses is lower. The first magnetic induction sensor senses the intensity of the first magnetic field and generates a corresponding electrical signal. Based on this electrical signal, it determines the rotation angle of the rotating component to determine whether the rotating component has rotated to the correct position (or whether it is jammed), thereby determining whether the lifting device has raised or lowered to the correct position. If the camera device has not raised or lowered to the correct position, the rotating component can be automatically controlled to rotate (or the user can further control the rotation of the rotating component) to make it rotate to the correct position, thereby ensuring that the lifting device and camera device are raised or lowered to the correct position, thus avoiding any impact on the imaging quality and lifespan of the camera device.

[0089] The following will combine Figures 1-24 The electronic device 100 provided in the embodiments of this application will be described.

[0090] This application provides an electronic device 100, which may include, but is not limited to, mobile terminals or fixed terminals such as mobile phones, tablets, laptops, ultra-mobile personal computers (UMPCs), handheld computers, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), dashcams, and security equipment.

[0091] In the embodiments of this application, see Figure 1 and Figure 2As shown, the above-mentioned electronic device 100 is described using a mobile phone as an example. The mobile phone can be a foldable mobile phone. The foldable mobile phone can be an inward foldable mobile phone (i.e., the display screen 110 folds inward) or an outward foldable mobile phone (i.e., the display screen 110 folds outward); the mobile phone can also be a candybar mobile phone.

[0092] In this embodiment of the application, a candybar mobile phone is used as an example.

[0093] See Figure 3 As shown, the mobile phone may include: a display screen 110, a back cover 120, a mid-frame 130 located between the display screen 110 and the back cover 120, a main circuit board 140, and a battery 150. The main circuit board 140 and the battery 150 may be disposed on the mid-frame 130. For example, the main circuit board 140 and the battery 150 may be disposed on the side of the mid-frame 130 facing the back cover 120, or the main circuit board 140 and the battery 150 may be disposed on the side of the mid-frame 130 facing the display screen 110. When the main circuit board 140 is disposed on the mid-frame 130, an opening may be provided in the mid-frame 130 to accommodate components on the main circuit board 140 within the opening.

[0094] The battery 150 can be connected to the charging management module and the main circuit board 140 via a power management module. The power management module receives input from the battery 150 and / or the charging management module, and supplies power to the processor, internal memory, external memory, display screen 110, and communication module. The power management module can also monitor parameters such as battery 150 capacity, battery 150 cycle count, and battery 150 health status (leakage current, impedance). In some other embodiments, the power management module can be located within the processor of the main circuit board 140. In still other embodiments, the power management module and the charging management module can be housed in the same device.

[0095] The display screen 110 can be an organic light-emitting diode (OLED) display screen or a liquid crystal display (LCD) display screen.

[0096] The back cover 120 can be a metal back cover, a glass back cover, a plastic back cover, or a ceramic back cover. In this embodiment of the application, the material of the back cover 120 is not limited.

[0097] Continue to refer to Figure 3The middle frame 130 may include a middle plate 132 and a frame 131. The frame 131 may surround the outer periphery of the middle plate 132. The frame 131 may include a top frame, a bottom frame, a left frame, and a right frame, which together form a ring-shaped frame 131. The middle plate 132 may be made of aluminum, aluminum alloy, or magnesium alloy; the material of the middle plate 132 is not limited. The frame 131 may be a metal frame or a ceramic frame; the material of the frame 131 is not limited. The middle plate 132 and the frame 131 may be snap-fitted, welded, glued, or integrally formed, or the middle plate 132 and the frame 131 may be fixedly connected by injection molding.

[0098] In some other examples, the mobile phone may include, but is not limited to, […]. Figure 3 The structure shown, such as a mobile phone, may include: a display screen 110, a mid-plate 132, and a housing, the housing including a frame 131 and a back cover 120. For example, the housing may be a housing formed by integrally molding the frame 131 and the back cover 120. The main circuit board 140 and the battery 150 may both be located in the accommodating space enclosed by the display screen 110 and the housing.

[0099] The mobile phone may also include a camera device 200 and a flash (not shown) to enable shooting. At least a portion of the camera device 200 may be located within the accommodating space enclosed by the display screen 110 and the housing. The camera device 200 may include a front-facing camera and a rear-facing camera. The rear-facing camera and flash may be disposed on the side of the middle plate 132 facing the rear cover 120, and the rear cover 120 has mounting holes 121 for mounting the rear-facing camera. The front-facing camera may be disposed on the side of the middle plate 132 facing the display screen 110. In this embodiment, the placement of the front-facing camera and the rear-facing camera is not limited to those described above. In some embodiments, the number of front-facing and rear-facing cameras disposed within the mobile phone may be one or N, where N is a positive integer greater than 1.

[0100] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the electronic device 100. In other embodiments of this application, the electronic device 100 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0101] Based on the above description, this application embodiment takes the scenario of setting a rear camera device in a mobile phone as an example for illustration. In other examples, the rear camera device can also be used as a front camera device.

[0102] like Figure 2 and 3 As shown, the back cover 120, the frame 131, and the display screen 110 surround and form an accommodating space, in which at least a portion of the camera device 200 is located, in order to reduce the volume of the camera device 200 protruding from the outside of the phone and reduce the impact of the camera device 200 on the appearance of the phone. For example, the camera device 200 may be partially located in the accommodating space, or the camera device 200 may be completely located in the accommodating space.

[0103] The back cover 120 is provided with mounting holes 121, which can be located at the edge of the back cover 120 or at the center of the back cover 120. In other examples, the mounting holes 121 can also be located on any side of the frame 131 or at a corner of the frame 131.

[0104] The camera device 200 provided in the embodiments of this application will be described in detail below.

[0105] See Figure 4 The camera device 200 may include a lifting device and a camera module 220, with the camera module 220 mounted on the lifting device. The lifting device may include a support member 210, a drive assembly, a rotating member 230, and a lifting member 240. The support member 210 can be used to support other structural components, providing protection for them and contributing to the overall mechanical strength of the camera device 200.

[0106] See Figure 5 and Figure 6 The support member 210 may include a support base 211, a drive assembly (which may be a first drive assembly) mounted on the support base 211, and a rotating member 230 rotatably mounted on the support base 211. The first drive assembly cooperates with the rotating member 230, which drives the lifting member 240 to rise and fall during rotation. The first drive assembly drives the rotating member 230 to rotate, and through the rotating member 230, drives the lifting member 240 to rise and fall. As the lifting member 240 rises, the volume between the lifting member 240 and the rotating member 230 along the thickness direction of the lifting device increases, and the volume of the lifting device along the thickness direction of the camera device 200 also increases, thereby increasing the volume of the camera device 200 along the thickness direction. This increases the total track length (TTL) of the lens of the camera device 200, thereby improving the imaging quality of the camera device 200 and the electronic device 100.

[0107] For example, refer to Figure 5 and Figure 6The support base 211 may be provided with a drive receiving groove 2113 on the side facing the lifting member 240. The drive receiving groove 2113 is used to place the first drive assembly, thereby limiting and protecting the first drive assembly. The support base 211 may also be provided with a slide rail 2114 on the side facing the lifting member 240. At least a part of the rotating member 230 is located in the slide rail 2114 and rotates along the slide rail 2114 under the drive of the first drive assembly. The inner wall surface of the slide rail 2114 may include a first inner wall surface and a second inner wall surface that are radially opposite and spaced apart from each other along the rotating member 230. The rotating member 230 is located between the first inner wall surface and the second inner wall surface, and at least a portion of the first inner wall surface and the second inner wall surface is a first arc surface 2115, forming an arc-shaped slide rail 2114. At least a portion of the outer wall surface of the rotating member 230 is a second arc surface 232. The first arc surface 2115 and the second arc surface 232 cooperate with each other to cause the rotating member 230 to rotate along the inner wall surface of the slide rail 2114 under the action of the first driving assembly. The slide rail 2114 may include at least one of the first inner wall surface and the second inner wall surface.

[0108] See Figure 5 The support base 211 may include a first support part 2111 and a second support part 2112 connected together. The first support part 2111 is provided with a drive receiving groove 2113, and the second support part 2112 is provided with a slide 2114. Figure 6 Only the first support portion 2111 is shown, while the second support portion 2112 is not shown.

[0109] For example, the rotating member 230 and the lifting member 240 can be generally cylindrical, with an accommodating area inside each member. The camera module 220 is at least partially located within this accommodating area and moves up and down within it, thereby reducing the volume occupied by the camera module 220 and providing protection for it. When the camera module 220 is in the retracted state, the rotating member 230 and the lifting member 240 can at least partially overlap each other, resulting in a smaller overall thickness. At least a portion of the lifting member 240 can be fitted over at least a portion of the rotating member 230; or, at least a portion of the rotating member 230 can be fitted over at least a portion of the lifting member 240. Alternatively, along the thickness direction of the camera device 200, the rotating member 230 and the lifting member 240 can be spaced apart to avoid mutual interference during assembly.

[0110] like Figure 2 and Figure 7As shown, the mobile phone may include a first direction X, a second direction Y, and a third direction Z. The first direction X, the second direction Y, and the third direction Z are all different, and they can be perpendicular to each other. For example, the first direction X can be the width direction of the mobile phone; the second direction Y can be the length direction of the mobile phone; and the third direction Z can be the thickness direction of the mobile phone. The length, width, and thickness in this embodiment are merely for descriptive convenience and do not imply any limitation on the dimensions. For example, the width can be greater than, equal to, or less than the length. The orientation of the mobile phone can be consistent with the orientation of the camera device 200, the first driving component, and the camera module 220, etc.

[0111] The lifting direction of the camera module 220 and the lifting member 240 may include, but is not limited to, a first direction X (X direction), a second direction Y (Y direction), or a third direction Z (Z direction). This embodiment of the application uses the Z direction as an example to illustrate the lifting direction of the camera module and the lifting member 240.

[0112] The following describes the lifting method of the camera module 220 in the embodiments of this application.

[0113] In some examples, the camera module 220 may include a camera and a second drive component. The second drive component is connected to the camera and can be used to drive the camera to rise and fall. Additionally, the second drive component can also be used to adjust the focus. When the first drive component drives the rotating member 230 to rotate in a first rotation direction, the rotating member 230 drives the lifting member 240 to rise. The lifting member 240 and the supporting base 211 are positioned along a third direction Z (…). Figure 7 The increased distance between the rotating member 230 and the lifting member 240 increases the accommodating area within them; the camera rises under the action of the second drive assembly, thereby increasing the overall length of the lens of the camera device 200 to improve the imaging quality of the camera device 200 and the electronic device 100. When the first drive assembly drives the rotating member 230 to rotate along the second rotation direction, and the rotating member 230 drives the lifting member 240 to descend, the distance between the lifting member 240 and the supporting base 211 along the third direction Z ( Figure 7 The reduced distance between the rotating component 230 and the lifting component 240 decreases the accommodating area within them; the camera descends under the action of the second drive assembly, thereby reducing the volume of the camera device 200. This process is repeated to achieve the lifting and lowering of the camera. Since the lifting and lowering of the camera is controlled by the second drive assembly, the lifting component 240 does not control the lifting and lowering of the camera. The lifting component 240 is decoupled from the camera, thus avoiding the influence of the lifting component 240 on the lifting and lowering accuracy of the camera. The number of structural components affecting the lifting and lowering accuracy of the camera is reduced, improving the controllability of the lifting and lowering accuracy of the camera and ensuring the shooting performance of the camera device 200.

[0114] In other examples, the camera module 220 is mounted on the lifting member 240, which in turn moves the camera module 220 up and down. When the first drive assembly drives the rotating member 230 to rotate in the first rotation direction, and the rotating member 230 moves the lifting member 240 up, the lifting member 240 moves the camera module 220 up as well. Both the lifting member 240 and the camera module 220 are positioned relative to the support base 211 along a third direction Z (…). Figure 7 The distance increases. When the first drive component drives the rotating member 230 to rotate in the second rotation direction, and the rotating member 230 drives the lifting member 240 to descend, the lifting member 240 drives the camera module 220 to descend. Both the lifting member 240 and the camera module 220 are located at a distance from the bearing base 211 along the third direction Z. Figure 7 The distance between them decreases. This process is repeated to achieve the raising and lowering of the camera. Since the raising component 240 and the camera module 220 rise and fall synchronously, the raising and lowering consistency between the camera module 220 and the raising component 240 is good. Furthermore, no other structural components are needed to determine the raising and lowering consistency between the camera module 220 and the raising component 240, making the structure of the camera module 220 relatively simple. The camera module 220 may include a connected focusing motor and a camera; the focusing motor is used to adjust the focal length.

[0115] This application uses the example of a second driving component driving the camera to rise and fall to illustrate the embodiments.

[0116] A camera may include a lens, which may include a lens barrel and multiple lenses located within the lens barrel. The lenses may be plastic lenses or glass lenses.

[0117] The lens can be a 5P lens (5 lenses), a 6P lens (6 lenses), or similar lenses, depending on the number of lens elements. For example, a 5P lens can have 5 plastic lenses, or 4 plastic lenses and 1 glass lens; a 6P lens can have 6 plastic lenses, or 5 plastic lenses and 1 glass lens. The number of lens elements in a lens is not limited to 5 or 6; it can be any number greater than or equal to 2.

[0118] At least a portion of the camera module 220 may be located on the side of the support base 211 facing the lifting member 240, thereby allowing the first drive assembly and the camera module 220 to overlap in the thickness direction, thereby reducing the overall thickness of the camera device 200.

[0119] like Figure 5As shown, a hollow area 2116 is provided on the support base 211, and the camera module 220 passes through the hollow area 2116. A portion of the camera module 220 is located on the side of the support base 211 facing the lifting member 240. The slide rail 2114 may be located on the outer periphery of the hollow area 2116. The portion of the camera module 220 located on the side of the support base 211 facing the lifting member 240 passes through the rotating member 230 and is located within the receiving area. This portion of the camera module 220 may include a camera, a second drive assembly, etc. Another part of the camera module 220 is located on the side of the support base 211 away from the lifting member 240. The camera module 220 located on the side of the support base 211 away from the lifting member 240 may include an optical image stabilization structure. The optical image stabilization structure occupies a large area in the XY plane. Setting the optical image stabilization structure on the side of the support base 211 away from the lifting member 240 can avoid the influence of the optical image stabilization structure on the volume of the rotating member 230 and the lifting member 240, which is conducive to the miniaturization of the camera device 200.

[0120] The following is a description of the state of the camera device 200 provided in the embodiments of this application.

[0121] like Figure 6 As shown, the camera device 200 may include a retracted state, in which the camera and the lifting member 240 are not extended from the camera device 200. In this state, the thickness of the camera device 200 is small, the overall thickness of the electronic device 100 is low, and the camera device 200 has little impact on the appearance of the electronic device 100.

[0122] The camera device 200 may include an extended state, in which the camera and lifting member 240 move away from the support base 211. For example, the camera and lifting member 240 extend along the rear cover 120 away from the display screen 110. In this state, the thickness of the camera device 200 increases, its available optical space is larger, and the overall length of the lens increases, resulting in better image quality and thus improving the imaging quality of both the camera device 200 and the electronic device 100. The thickness of the camera device 200 is no longer limited by the thickness of the electronic device 100, allowing the electronic device 100 to be made thinner, which is beneficial for the miniaturization of the electronic device 100.

[0123] Of course, the camera device 200 can also be in an intermediate state between the extended state and the retracted state. When the camera device 200 is in the extended, retracted, or intermediate state, the lifting member 240 and the camera can also be in the same state.

[0124] The protective cover provided in the embodiments of this application will be described below.

[0125] like Figure 7As shown, the lifting device may include a protective cover, which may include a top protective cover 281. The top protective cover 281 is connected to the side of the lifting member 240 opposite to the support base 211. The top protective cover 281 is a structural component for lifting and lowering, and it rises and falls with the lifting member 240. When an external force is applied to the camera device 200, the force first acts on the top protective cover 281. The top protective cover 281 can protect the camera device 200. There is a gap between the top protective cover 281 and the camera module 220 along the thickness direction of the camera device 200. When an external force is applied to the top protective cover 281, there is a buffer space between the top protective cover 281 and the camera module 220. The top protective cover 281 needs to move a certain distance toward the support base 211 before it can contact the camera module 220, thus preventing the external force from directly acting on the camera module 220 through the top protective cover 281, thereby protecting the camera module 220.

[0126] A light-transmitting hole 283 can be provided in the middle area of ​​the top protective cover 281, and a light-transmitting element 282 is provided to cover the light-transmitting hole 283. The lens and the light-transmitting element 282 are positioned opposite each other along the Z direction. In this way, during shooting, external light can enter the lens through the light-transmitting element 282. The light-transmitting element 282 can be connected to the top protective cover 281 by means of snap-fit, adhesive, or other methods.

[0127] Along the thickness direction of the camera device 200, there is always a gap between the camera module 220 and the top protective cover 281. The existence of this gap can prevent external forces from acting directly on the camera module 220 through the top protective cover 281, thereby protecting the camera module 220.

[0128] In some embodiments, the protective cover may further include a first cover body, which may extend along the plane (XY plane) where the support base 211 is located. The first cover body is located on the side of the support base 211 facing the lifting member 240 and may be connected to the support base 211. The first cover body may be arranged around the outer periphery of the lifting member 240. The first cover body may cover the opening of the drive receiving groove 2113, thereby creating a relatively sealed environment between the first support portion 2111 and the first cover body. The first cover body may also cover the side of the slide 2114 facing the lifting member 240, thereby creating a relatively sealed environment between the second support portion 2112 and the first cover body. The first cover body is a stationary structural component and does not undergo lifting or lowering movement.

[0129] In some embodiments, the protective cover may further include a second cover body extending along the thickness direction (Z direction) of the camera device 200. The second extension is fitted over the outside of the lifting member 240. The second cover body may be generally cylindrical in shape. The second cover body protects structural components located inside the second cover body. The second cover body may be directly connected to the support base 211 or indirectly connected to the support base 211 through other structural components. For example, the second cover body may be connected to the support base 211 through a first cover body. The end of the second cover body facing the support base 211 may be connected to the inner edge of the first cover body.

[0130] For example, a limiting component can be provided between the lifting member 240 and the second cover to prevent the lifting member 240 from rotating under the influence of the rotating member 230. If the lifting member 240 also rotates when the rotating member 230 rotates, the rotational motion of the rotating member 230 cannot be converted into the lifting motion of the lifting member 240. Therefore, a limiting component is needed to restrict the rotation of the lifting member 240 in the XY plane. The limiting component may include a limiting protrusion and a limiting recess. One of the limiting protrusion and the limiting recess is located on the outer wall surface of the lifting member 240, and the other is located on the inner wall surface of the second cover. The limiting protrusion is located in the limiting recess and moves along the Z direction in the limiting recess. By providing the limiting protrusion and the limiting recess, the rotation of the lifting member 240 in the XY plane can be restricted. In addition, it can also guide the lifting direction of the lifting member 240.

[0131] See Figure 8 The camera device 200 may include a guide member 250, which includes a first end 251 and a second end 252 disposed opposite to each other along the thickness direction of the camera device 200. One of the rotating member 230 and the lifting member 240 is provided with a guide channel 260, which is inclined relative to the lifting direction of the lifting member 240. The other of the rotating member 230 and the lifting member 240 is connected to the first end 251 of the guide member 250. The second end 252 of the guide member 250 is provided with a protrusion 253 that mates with the guide channel 260. The protrusion 253 is inserted into the guide channel 260 and moves along the extending direction of the guide channel 260.

[0132] The guide channel 260 and guide member 250 provided in the embodiments of this application will be described below.

[0133] In the first implementation, see Figure 8 and Figure 9The guide channel 260 can be disposed on the lifting member 240. The first end 251 of the guide member 250 is connected to the rotating member 230. The protrusion 253 of the second end 252 of the guide member 250 is inserted into the guide channel 260 of the lifting member 240 and moves along the extension direction of the guide channel 260. The first drive assembly drives the rotating member 230 to rotate, and the rotating member 230 drives the guide member 250 to rotate. The guide member 250 moves along the guide channel 260 during rotation. Since the guide channel 260 is inclined, the end of the guide channel 260 facing the support base 211 is closer to the support base 211, and the end of the guide channel 260 away from the support base 211 is farther away from the support base 211. When the protrusion 253 is located at the end of the guide channel 260 facing the support base 211, the lifting member 240 is in the extended state; when the protrusion 253 is located at the end of the guide channel 260 away from the support base 211, the lifting member 240 is in the retracted state.

[0134] In the second embodiment, the guide channel 260 can be disposed on the rotating member 230. The first end 251 of the guide member 250 is connected to the lifting member 240, and the protrusion 253 of the second end 252 of the guide member 250 is inserted into the guide channel 260 of the rotating member 230 and moves along the extension direction of the guide channel 260. The first driving assembly drives the rotating member 230 to rotate, and the rotating member 230 drives the guide channel 260 to rotate. The guide channel 260 moves relative to the guide member 250 during the rotation. Since the guide channel 260 is inclined, the end of the guide channel 260 facing the support base 211 is closer to the support base 211, and the end of the guide channel 260 away from the support base 211 is farther from the support base 211. When the protrusion 253 is located at the end of the guide channel 260 facing the support base 211, the lifting member 240 is in a retracted state; when the protrusion 253 is located at the end of the guide channel 260 away from the support base 211, the lifting member 240 is in an extended state.

[0135] This application embodiment takes the example of a guide channel 260 being installed on the lifting member 240 and the first end 251 of the guide member 250 being connected to the rotating member 230.

[0136] The guide channel 260 can penetrate the outer and inner walls of the lifting member 240 radially. The guide channel 260 can also be formed by a groove provided on the outer or inner wall of the lifting member 240. The second end 252 can be located inside the lifting member 240, and the protrusion 253 is inserted into the guide channel 260 from the inside of the lifting member 240. Alternatively, as... Figure 10 As shown, the second end 252 can be located on the outside of the lifting member 240, and the protrusion 253 is inserted into the guide channel 260 from the outside of the lifting member 240.

[0137] In this design, the guide member 250 and the rotating member 230 can be fixedly connected, thereby ensuring high stability of the connection between them. For example, the guide member 250 and the rotating member 230 can be fixedly connected by means of bonding, welding, or integral molding. In other examples, the guide member 250 and the rotating member 230 can be detachably connected, facilitating the installation and removal of the guide member 250. The principle of setting the guide channel 260 on the rotating member 230 is similar and will not be described further.

[0138] The following describes the guide channel 260 provided in the embodiments of this application.

[0139] like Figure 10 As shown, the guide channel 260 has a first channel 260a at one end facing the support base 211, and a second channel 260b at the other end away from the support base 211. Both the first channel 260a and the second channel 260b can extend along the XY plane, and the inner wall surfaces of the first channel 260a and the second channel 260b can be parallel to the XY plane, thereby making the contact area between the protrusion 253 and the inner wall surface of the first channel 260a or the second channel 260b larger. When the protrusion 253 is located in the first channel 260a or the second channel 260b, the mutual support between the protrusion 253 and the inner wall of the first channel 260a or the second channel 260b is good. The protrusion 253 can be stably located in the first channel 260a or the second channel 260b, which can prevent the protrusion 253 from sliding due to being in the inclined guide channel 260 when it is in the extended or retracted state. This allows the lifting member 240 to be stably in the extended or retracted state, preventing the camera device 200 from shaking and ensuring the shooting effect of the camera device 200.

[0140] When the protrusion 253 moves within the guide channel 260, the lifting member 240 switches between an extended state and a retracted state. (See also...) Figure 10 In the embodiment where the guide channel 260 is located at the lifting member 240, when the protrusion 253 is located at the first channel 260a, the lifting member 240 is in an extended state; when the protrusion 253 is located at the second channel 260b, the lifting member 240 is in a retracted state. In the embodiment where the guide channel 260 is located at the rotating member 230, when the protrusion 253 is located at the first channel 260a, the lifting member 240 is in a retracted state; when the protrusion 253 is located at the second channel 260b, the lifting member 240 is in an extended state.

[0141] For example, the end face of the protrusion 253 in the axial direction of the rotating member 230 is a planar structure, while both ends of the planar structure are curved surfaces. This allows for smooth engagement between the protrusion 253 and the guide channel 260, preventing wear and scratches on the guide channel 260 caused by the protrusion 253, thereby preventing lifting jamming and extending the service life of both the protrusion 253 and the guide channel 260. Of course, the protrusion 253 can also have other shapes, such as an arc-shaped end face in the axial direction of the rotating member 230. This application does not limit the scope of the embodiments described.

[0142] See Figure 11 The distance between the first channel 260a and the second channel 260b in the axial direction of the lifting member 240 is a first distance L1, which is the maximum distance the lifting member 240 can rise or fall along the Z direction. The distance between the first channel 260a and the second channel 260b in the circumferential direction of the lifting member 240 is a second distance L2. When the rotating member 230 drives the protrusion 253 to move a distance equal to one second distance L2 along the circumferential direction of the lifting member 240 in the guide channel 260, the lifting member 240 can rise or fall by one first distance L1 along the Z direction. In addition, a toothed structure 233 is provided on the outer side of the rotating member 230. Figure 11 The tooth structure 233 is disposed at one end of the rotating member 230 near the bearing base 211 to facilitate engagement of the first drive assembly. The length of the rotating member 230 covered by the tooth structure 233 in the circumferential direction is greater than or equal to the second spacing L2.

[0143] Wherein, a baffle 263 is provided at the end of the first channel 260a away from the second channel 260b and at the end of the second channel 260b away from the first channel 260a; the baffle 263 is used to restrict the protrusion 253 in the guide channel 260.

[0144] For example, the protrusion 253 may include an upper end face and a lower end face that are spaced apart along the axial direction of the lifting member 240, with the lower end face located on the side of the protrusion 253 facing the support base 211 and the upper end face located on the side of the protrusion 253 away from the support base 211.

[0145] In some embodiments, see Figure 10 The guide channel 260 may include a first driving surface 261, which is located on the side of the protrusion 253 opposite to the first end 251.

[0146] In the embodiment where the guide channel 260 is located within the lifting member 240, the first driving surface 261 and the upper end surface of the protrusion 253 are arranged facing each other. When the guide member 250 drives the protrusion 253 to move from the second channel 260b to the first channel 260a, the upper end surface of the protrusion 253 abuts against the first driving surface 261, pushing the lifting member 240 upward. Furthermore, when the protrusion 253 is stationary, the upper end surface of the protrusion 253 supports the first driving surface 261, thus supporting the lifting member 240.

[0147] In the embodiment where the guide channel 260 is located at the rotating member 230, the first driving surface 261 is disposed facing the lower end surface of the protrusion 253. When the rotating member 230 drives the guide channel 260 to move along the direction from the second channel 260b to the first channel 260a, the first driving surface 261 abuts against the lower end surface of the protrusion 253 and pushes the guide member 250 to rise, which in turn drives the lifting member 240 to rise. In addition, when the protrusion 253 is stationary, the first driving surface 261 provides support for the lower end surface of the protrusion 253, thereby providing support for the guide member 250 and the lifting member 240.

[0148] See some examples. Figure 10 The first driving surface 261 can be planar, thus making its structure relatively simple and its fabrication easier. See also other examples. Figure 11 The first driving surface 261 can be curved, and the curved surface bends toward the descending direction of the lifting member 240 (equivalent to the retraction direction). When the first driving surface 261 is curved, the extension length of the curved surface is longer than the extension length of the plane. When the lifting member 240 moves the same distance along the third direction Z, the distance that the protrusion 253 moves on the curved surface is longer than the distance it moves on the plane, thereby improving the lifting accuracy of the lifting member 240.

[0149] In some embodiments, see also [link to previous document]. Figure 10 and Figure 11 The guide channel 260 may include a second drive surface 262 spaced apart from the first drive surface 261, the second drive surface 262 being located on the side of the protrusion 253 facing the first end 251.

[0150] In the embodiment where the guide channel 260 is located in the lifting member 240, the second driving surface 262 is disposed facing the lower end surface of the protrusion 253. When the guide member 250 drives the protrusion 253 to move from the first channel 260a to the second channel 260b, the lower end surface of the protrusion 253 abuts against the second driving surface 262 and pushes the lifting member 240 down.

[0151] In the embodiment where the guide channel 260 is located in the rotating member 230, the second driving surface 262 is arranged facing the upper end surface of the protrusion 253. When the rotating member 230 drives the guide channel 260 to move along the direction from the first channel 260a to the second channel 260b, the second driving surface 262 abuts against the upper end surface of the protrusion 253 and pushes the guide member 250 down, and the guide member 250 then drives the lifting member 240 down.

[0152] In some examples, the second driving surface 262 can be a plane, making its structure simpler and its fabrication easier. When the second driving surface 262 is curved, the curved surface bends towards the descending direction of the lifting member 240 (equivalent to the retraction direction). The extension length of the curved surface is longer than that of the plane. When the lifting member 240 moves the same distance along the third direction Z, the protrusion 253 moves a longer distance on the curved surface than on the plane, thereby improving the lifting accuracy of the lifting member 240.

[0153] Taking the guide channel 260 located at the lifting member 240 as an example, when the guide member 250 drives the protrusion 253 to move from the first channel 260a to the second channel 260b, the horizontal driving force applied by the protrusion 253 to the second driving surface 262 is located in the XY plane. The horizontal driving force is converted into a lifting driving force along the third direction Z through the second driving surface 262, and the lifting driving force is used to drive the lifting member 240 to descend. The horizontal driving force can be a fixed value, and the angle between the second driving surface 262 and the XY plane (…). Figure 10 The smaller the included angle α, the greater the lifting driving force obtained by converting the horizontal driving force through the second driving surface 262. (See also...) Figure 12 S1 shows the shape of the cross-section when the second driving surface 262 is a plane, and S2 shows the shape of the cross-section when the second driving surface 262 is a curved surface. See also Figure 13S1 shows the change in lifting driving force with the rotation angle of the rotating member 230 when the second driving surface 262 is a plane, and S2 shows the change in lifting driving force with the rotation angle of the rotating member 230 when the second driving surface 262 is a curved surface. The rotation angle of the rotating member 230 corresponds to the height of the guide channel 260. When the rotation angle of the rotating member 230 increases, the height of the guide channel 260 corresponding to the protrusion 253 decreases, and the lifting member 240 descends. When the second driving surface 262 is a plane, the angle between the second driving surface 262 and the XY plane is a fixed value, and the lifting driving force obtained by converting the horizontal driving force through the second driving surface 262 is equal everywhere. When the second driving surface 262 is a curved surface, the curved surface bends towards the descending direction of the lifting member 240 (equivalent to the retraction direction), causing the angle between the second driving surface 262 and the XY plane to gradually decrease along the descending direction. The lifting driving force obtained by converting the horizontal driving force through the second driving surface 262 gradually increases along the descending direction, thus satisfying certain application scenarios where the lifting driving force needs to gradually increase along the descending direction. For example, a second elastic element can be provided between the lifting member 240 and the supporting base 211. The second elastic element can be in a compressed state, providing a thrust to the lifting member 240 to make it easier for the lifting member 240 to extend. During the retraction of the lifting member 240, the degree of compression of the second elastic element gradually increases, thus requiring a gradual increase in the lifting driving force required to retract the lifting member 240. Therefore, by setting the second driving surface 262 as a curved surface, the lifting driving force can be made variable, so that the actual lifting driving force matches the magnitude of the lifting driving force required for the lifting member 240 to retract.

[0154] The guide channel 260 may include a first driving surface 261 and a second driving surface 262. The lifting member 240 can rise under the interaction of the first driving surface 261 and the protrusion 253; the lifting member 240 can fall under the interaction of the second driving surface 262 and the protrusion 253; thus, the lifting member 240 can be raised and lowered through the interaction of the protrusion 253 with the first driving surface 261 and the second driving surface 262.

[0155] Alternatively, the guide channel 260 can only have a first driving surface 261 without a second driving surface 262, thus simplifying the structure of the guide channel 260. The lifting member 240 can rise under the interaction force between the first driving surface 261 and the protrusion 253. However, since the second driving surface 262 is not provided, the lifting member 240 cannot descend via the second driving surface 262. The camera device 200 may include a first elastic member, which provides an elastic driving force to the lifting member 240 toward the support base 211 to drive the lifting member 240 to descend. Taking the guide channel 260 located on the lifting member 240 as an example, when the protrusion 253 moves from the first channel 260a to the second channel 260b, the upper surface of the protrusion 253 will no longer support the first driving surface 261, meaning the protrusion 253 no longer supports the lifting member 240. Under the elastic driving force of the first elastic member, the lifting member 240 moves toward the support base 211, and the lifting member 240 descends. As the protrusion 253 moves continuously from the first channel 260a to the second channel 260b, the first elastic element continuously drives the lifting element 240 to descend, thereby realizing the retraction of the lifting element 240.

[0156] For example, the number of guide channels 260 may include at least one. When there are multiple guide channels 260, there may also be multiple guide members 250, with each guide member 250 corresponding to a guide channel 260. When there are multiple guide members 250, they are spaced apart on the circumference of the rotating member 230. For example, the multiple guide members 250 may be evenly distributed on the circumference of the rotating member 230. The distances between the multiple protrusions 253 and the bearing base 211 may be the same, which can ensure uniform force on the lifting member 240, thereby enabling stable upward or downward movement. The number of guide members 250 may include, but is not limited to, two, three, four, five, or six or more. The guide members 250 may be axially symmetrical or centrally symmetrically distributed, thereby ensuring relatively uniform force on each guide member 250. Alternatively, the guide members 250 may be asymmetrically distributed.

[0157] The rotation angle of the detection rotating member 230 provided in the embodiments of this application will be described below.

[0158] The lifting device may include an angle detection component and a control component. The control component is electrically connected to both the angle detection component and the camera module 220. The control component may be a control chip mounted on the main circuit board 140, such as a microcontroller unit (MCU) or a central processing unit (CPU). The angle detection component is configured to detect the rotation angle of any rotating structural component relative to any stationary structural component. The control component is used to acquire the angle detected by the angle detection component and can determine the change in the rotation angle of any rotating structural component relative to any stationary structural component.

[0159] For example, see Figure 14 and Figure 15 The angle detection device may include a first magnetic induction sensor 271 and a first magnetic element 272. One of the first magnetic induction sensor 271 and the first magnetic element 272 is connected to a stationary structural component, and the other is connected to a rotating structural component. This application does not limit the scope of the detection device as long as the relative rotation angle between the rotating and stationary structural components can be determined. The first magnetic induction sensor 271 is electrically connected to a control unit, which acquires the electrical signal from the first magnetic induction sensor 271.

[0160] For example, stationary structural components remain stationary during the lifting process of the lifting device. These stationary structural components may include, but are not limited to, the load-bearing component 210, the rear cover 120, the middle frame 130, the first cover, and the second cover. Rotating structural components are driven to rotate by the rotating component 230 during the lifting process of the lifting device. These rotating structural components may include, but are not limited to, the rotating component 230 or the guide component 250 (when the guide component 250 is connected to the rotating component 230).

[0161] This application uses a stationary structural component as the load-bearing component 210 and a rotating structural component as the rotating component 230 as an example for illustration.

[0162] When the rotating component 230 rotates in the first rotation direction, the rotation angle of the rotating component 230 relative to the bearing component 210 increases. When the rotating component 230 rotates in the second rotation direction, the rotation angle of the rotating component 230 relative to the bearing component 210 decreases. When the control component determines that the rotation angle between the rotating component 230 and the bearing component 210 has increased, the control component controls the second drive assembly to drive the camera away from the bearing base 211, so that the camera rises. When the control component determines that the rotation angle between the rotating component 230 and the bearing component 210 has decreased, the control component controls the second drive assembly to drive the camera toward the bearing base 211, so that the camera falls. In this way, the camera can be raised and lowered by the cooperation of the angle detection component and the control component. In addition, the angle detection component can also determine whether the rotating component 230 has rotated to the correct position or is jammed, thereby determining whether the lifting device has reached the correct position. If the lifting device fails to reach its designated position, the control unit can automatically rotate the rotating component 230 (or the user can further control the rotation of the rotating component 230) to ensure it reaches its correct position. This will allow the lifting device and camera device 200 to be raised or lowered accordingly, thus preventing any impact on the imaging quality and lifespan of the camera device 200. If the control unit determines that the lifting device has not reached its designated position and attempts to rotate the rotating component 230 again without success, it can alert the user that the rotating component 230 is malfunctioning. The user can then remove any foreign objects from the lifting device or take it to a repair shop for maintenance.

[0163] The first magnetic element 272 can be used to generate a first magnetic field. The first magnetic induction sensor 271 can be located in the first magnetic field. The rotating element 230 can be used to move one of the first magnetic induction sensor 271 and the first magnetic element 272 closer to or further away from the other during rotation. When the first magnetic induction sensor 271 and the first magnetic element 272 are close to each other, the magnetic field strength sensed by the first magnetic induction sensor 271 is larger; when the first magnetic induction sensor 271 and the first magnetic element 272 are far apart, the magnetic field strength sensed by the first magnetic induction sensor 271 is smaller. The first magnetic induction sensor 271 can convert the sensed magnetic field strength of the first magnetic element 272 into an electrical signal. By analyzing the correspondence between the electrical signal and the rotation angle, the magnitude of the rotation angle can be obtained. For example, the camera device 200 may include a memory chip, which can be electrically connected to the control unit. The memory chip can be an electrically erasable programmable read-only memory (E2PROM) chip. E2PROM chips retain data even after power loss and are plug-and-play, making them convenient to use. The storage chip can be used to store the initial correspondence between the electrical signal of the first magnetic induction sensor 271 and the rotation angle of the rotating component 230. See also... Figure 19 The storage chip is electrically connected to the control unit. The control unit can obtain the first correspondence from the storage chip in advance, and after obtaining the electrical signal of the first magnetic induction sensor 271, it performs calculations to obtain the rotation angle of the rotating part 230, so as to determine whether the rotating part 230 has rotated into place and whether there is jamming.

[0164] The first magnetic induction sensor 271 can be a Hall effect device or a tunnel magnetoresistance sensor (TMR). Taking a Hall effect device as an example, the Hall effect device and the first magnetic component 272 utilize the Hall effect to determine the rotation angle between the lifting component 240 and the supporting component 210. The Hall effect is the magnetoelectric effect; the Hall voltage changes with the magnetic field strength. The stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. The Hall effect device converts the magnetic signal into an electrical signal and transmits it to the control component, thereby controlling the rotation of the rotating component 230.

[0165] For example, there may be one first magnetic element 272. When the lifting device is in the retracted or extended state, the first magnetic element 272 and the first magnetic induction sensor 271 can be arranged opposite each other, so that the distance between the first magnetic element 272 and the first magnetic induction sensor 271 is relatively close. Taking the retracted state of the lifting device as an example, when the lifting device is in the retracted state, the magnetic field strength of the first magnetic element 272 sensed by the first magnetic induction sensor 271 is the greatest, which can more accurately determine the retracted state of the lifting device. During the extension of the lifting device, the first magnetic induction sensor 271 and the first magnetic element 272 move away from each other, and the magnetic field strength sensed by the first magnetic induction sensor 271 gradually decreases. During the retraction of the lifting device, the first magnetic induction sensor 271 and the first magnetic element 272 move closer to each other, and the magnetic field strength sensed by the first magnetic induction sensor 271 gradually increases.

[0166] In some embodiments, see Figure 14There can be two first magnetic elements 272, which can be spaced apart along the circumference of the rotating member 230. This arrangement ensures that the first magnetic field of the two first magnetic elements 272 covers a large area along the circumference of the rotating member 230. During the rotation of the rotating member 230, the first magnetic induction sensor 271 can be located within the first magnetic field, thus effectively measuring the rotation angle of the rotating member 230. Furthermore, since the rotation path of the rotating member 230 is relatively long, if only one first magnetic element 272 is used, it needs to be long and have a large bending angle along the circumference of the rotating member 230. By using two spaced first magnetic elements 272, the total extension length of the two first magnetic elements 272 is smaller, and the extension length and bending angle of each individual first magnetic element 272 can be set smaller, thereby reducing the cost and manufacturing difficulty of the first magnetic elements 272.

[0167] In some examples, the south-to-north pole directions of the two first magnetic elements 272 can be opposite along the circumference of the rotating member 230, or the south-to-north pole directions of the two first magnetic elements 272 can be opposite along the axial direction of the rotating member 230. With this arrangement, the magnetization directions of the two first magnetic elements 272 are opposite. In other examples, the south-to-north pole directions of the two first magnetic elements 272 can be the same along the circumference of the rotating member 230. This application embodiment does not limit the south-to-north pole directions of the two first magnetic elements 272.

[0168] This application embodiment is illustrated by taking as an example that the north and south poles of the two first magnetic elements 272 are arranged in opposite directions along the circumference or axial direction of the rotating member 230.

[0169] The rotating component 230 is used to move the first magnetic induction sensor 271 closer to one of the two first magnetic components 272 during rotation, and to move the first magnetic induction sensor 271 further away from the other of the two first magnetic components 272. For example, the two first magnetic components 272 are a first sub-magnetic component 2721 and a second sub-magnetic component 2722, respectively. When the lifting device is in the retracted state, the first sub-magnetic component 2721 is positioned opposite the first magnetic induction sensor 271, and the distance between the first sub-magnetic component 2721 and the first magnetic induction sensor 271 is the closest, so that the magnetic field strength of the first sub-magnetic component 2721 sensed in the retracted state is the greatest, thus more accurately determining the retracted state of the lifting device. When the lifting device is in the extended state, the second sub-magnetic component 2722 is positioned opposite the first magnetic induction sensor 271, and the distance between the second sub-magnetic component 2722 and the first magnetic induction sensor 271 is the closest, so that the magnetic field strength of the second sub-magnetic component 2722 sensed in the extended state is the greatest, thus more accurately determining the extended state of the lifting device. Furthermore, the north-south direction of the first sub-magnetic element 2721 and the second sub-magnetic element 2722 are opposite, and their magnetization directions are also opposite, resulting in a wider range of magnetic field strength between them. When the first magnetic induction sensor 271 moves relative to the first and second sub-magnetic elements 2721 and 2722, the magnetic intensity it senses changes significantly, thereby improving the sensitivity of measuring the rotation angle of the rotating member 230. When the rotating member 230 rotates along the first rotation direction (during the extension of the lifting device), the first magnetic induction sensor 271 approaches the second sub-magnetic element 2722 and moves away from the first sub-magnetic element 2721. The magnetic field strength sensed by the first magnetic induction sensor 271 of the first sub-magnetic element 2721 decreases, while the magnetic field strength sensed by the first magnetic induction sensor 271 of the second sub-magnetic element 2722 increases. When the rotating component 230 rotates along the second rotation direction (during the retraction process of the lifting device), the first magnetic induction sensor 271 approaches the first sub-magnetic component 2721 and moves away from the second sub-magnetic component 2722. The magnetic field strength of the first sub-magnetic component 2721 sensed by the first magnetic induction sensor 271 increases, while the magnetic field strength of the second sub-magnetic component 2722 sensed by the first magnetic induction sensor 271 decreases. Figure 16 The diagram shows the change in the magnetic field strength of the two first magnetic elements 272 sensed by the first magnetic induction sensor 271 when the rotating element 230 rotates.

[0170] For example, the first magnetic element 272 can be connected to the carrier 210, and the first magnetic induction sensor 271 can be connected to the rotating element 230. Alternatively, the first magnetic element 272 can be connected to the rotating element 230, and the first magnetic induction sensor 271 can be connected to the carrier 210. Since the first magnetic induction sensor 271 is electrically connected to the control element, an electrical connection structure needs to be provided between the first magnetic induction sensor 271 and the control element. When the first magnetic induction sensor 271 is connected to the carrier 210, it can avoid the electrical connection structure being easily damaged by pulling during rotation when the first magnetic induction sensor 271 is connected to the rotating element 230.

[0171] This application embodiment uses the example of a first magnetic element 272 connected to a rotating element 230 and a first magnetic induction sensor 271 connected to a supporting element 210 for illustration. For example, see... Figure 9 The rotating component 230 has an assembly portion 234 on its outer periphery. A toothed structure 233 is provided on the side of the assembly portion 234 opposite to the receiving area. The assembly portion 234 can extend into the drive receiving groove 2113, facilitating the engagement of the toothed structure 233 with the first drive assembly. A first receiving groove 231 can be provided on the assembly portion 234 to receive the first magnetic component 272. The opening of the first receiving groove 231 can be located on the surface of the assembly portion 234 facing the top protective cover 281, making the installation of the first magnetic component 272 more convenient. In some examples, the first magnetic induction sensor 271 can be disposed on the support base 211, thus simplifying the structure of the support component 210. In other examples, see... Figure 15 and Figure 17The carrier 210 may include a carrier circuit board 212 connected to the carrier base 211. The carrier circuit board 212 may include a first carrier circuit board 2121, on which a first magnetic induction sensor 271 is connected. The first magnetic induction sensor 271 can be electrically connected to a control component via the first carrier circuit board 2121. For example, the first magnetic induction sensor 271 can be surface-mounted onto the first carrier circuit board 2121. The first carrier circuit board 2121 may be positioned opposite and spaced apart from the rotating component 230 to prevent mutual wear between the rotating component 230 and the first carrier circuit board 2121 during rotation. The first magnetic induction sensor 271 may be located on the side of the first carrier circuit board 2121 facing the first magnetic component 272, and the first magnetic component 272 may be located on the side of the rotating component 230 facing the first magnetic induction sensor 271, thereby reducing the influence of the first carrier circuit board 2121 and the rotating component 230 on the magnetic field induction between the first magnetic component 272 and the first magnetic induction sensor 271. The first carrier circuit board 2121 can be a flexible printed circuit (FPC), facilitating the connection between the first carrier circuit board 2121 and the control components. The first carrier circuit board 2121 can be located on the side of the first cover facing the drive receiving groove 2113, and is connected to the first cover. The first cover supports the first carrier circuit board 2121, helping to keep it stationary. Alternatively, the first carrier circuit board 2121 can also be connected to stationary structural components such as the rear cover 120 or the middle frame 130 to provide support and help keep it stationary. Of course, the first carrier circuit board 2121 can also be a printed circuit board (PCB).

[0172] For example, see Figure 17 and Figure 18The lifting device may further include a first magnetic isolator 275, which is used to reduce interference from external magnetic fields on the first magnetic induction sensor 271. For example, the first magnetic isolator 275 may be a metal component or other structural component capable of isolating magnetic fields. In an embodiment where the first magnetic induction sensor 271 is connected to the side of the first carrier circuit board 2121 facing the first magnetic component 272, the first magnetic isolator 275 may be located on the side of the first carrier circuit board 2121 opposite to the first magnetic component 272, thereby preventing interference from external magnetic fields on the side of the first carrier circuit board 2121 opposite to the first magnetic component 272 on the first magnetic induction sensor 271. The first carrier circuit board 2121 may be connected to the first cover, the rear cover 120, or the middle frame 130 via the first magnetic isolator 275. The first magnetic isolator 275 can also enhance the mechanical strength of the first supporting circuit board 2121. The first magnetic isolator 275 can be connected to the first supporting circuit board 2121 before the first magnetic induction sensor 271, thereby facilitating the subsequent installation of the first magnetic induction sensor 271 and improving the fixing strength of the first magnetic induction sensor 271, preventing the first magnetic induction sensor 271 from falling off during drops, compression, and impacts. For example, the first magnetic isolator 275 can be connected to the first supporting circuit board 2121 by means of bonding, welding, etc.

[0173] The following describes the lifting distance of the detection lifting member 240 provided in the embodiments of this application.

[0174] The camera device 200 may include a distance detection element, and a control element is electrically connected to the distance detection element. The distance detection element is configured to detect the lifting distance between any stationary structural component and any lifting structural component. The control element is used to acquire the distance detected by the distance detection element and can determine the change in distance between the stationary structural component and the lifting structural component.

[0175] For example, see Figure 14 and Figure 15 The distance detection element may include a second magnetic induction sensor 273 and a second magnetic element 274. One of the second magnetic induction sensor 273 and the second magnetic element 274 is connected to a stationary structural component, and the other is connected to a lifting structural component. This application does not limit the scope of the distance detection to anything other than determining the distance between the stationary and lifting structural components. During the lifting process of the lifting device, the lifting structural component rises and falls under the influence of the lifting member 240. The number of second magnetic elements 274 may be one or two, and their principle is similar to that of the first magnetic element 272, which will not be described again.

[0176] For example, the lifting structural components may include, but are not limited to, lifting component 240, top protective cover 281, camera, or guide component 250 (when guide component 250 is connected to lifting component 240), etc.

[0177] This application uses a static structural component as the load-bearing component 210 and a lifting structural component as the lifting component 240 as an example for illustration.

[0178] The second magnetic sensor 273 is electrically connected to the control unit, which is used to acquire the electrical signal of the second magnetic sensor 273. The second magnetic element 274 can be used to generate a second magnetic field, and the second magnetic sensor 273 can be located in the second magnetic field. The lifting element 240 can be used to move one of the second magnetic sensor 273 and the second magnetic element 274 closer to or away from the other during the lifting process. Figure 20 The diagram illustrates the change in the intensity of the second magnetic field sensed by the second magnetic element 274 during the lifting process of the lifting element 240 when there is only one second magnetic element 274. For example, the second magnetic induction sensor 273 can be a Hall effect device or a tunnel magnetoresistive sensor, etc. Its principle is similar to that of the first magnetic induction sensor 271 and the first magnetic element 272, and will not be described further. See [link to documentation] Figure 19 The memory chip can also be used to store a second correspondence between the electrical signal of the second magnetic induction sensor 273 and the lifting position of the lifting member 240. The control unit can obtain the second correspondence from the memory chip in advance, and after obtaining the electrical signal of the second magnetic induction sensor 273, perform calculations to obtain the lifting position of the lifting member 240, so as to determine whether the lifting member 240 has reached the lifting position or is stuck.

[0179] When the controller determines that the distance between the lifting member 240 and the support member 210 increases, the controller moves the camera away from the support base 211 to raise the camera. When the controller determines that the distance between the lifting member 240 and the support member 210 decreases, the controller moves the camera towards the support base 211 to lower the camera. In this way, the camera can be raised and lowered through the cooperation of the distance detection device and the controller.

[0180] For example, the second magnetic element 274 can be connected to the support member 210, and the second magnetic induction sensor 273 can be connected to the lifting member 240. Alternatively, the second magnetic element 274 can be connected to the lifting member 240, and the second magnetic induction sensor 273 can be connected to the support member 210. Since the second magnetic induction sensor 273 is electrically connected to the control member, an electrical connection structure needs to be provided between the second magnetic induction sensor 273 and the control member. When the second magnetic induction sensor 273 is connected to the support member 210, it can avoid the electrical connection structure being easily damaged by pulling during the lifting process when the second magnetic induction sensor 273 is connected to the lifting member 240.

[0181] This application embodiment uses the example of a second magnetic component 274 connected to a lifting component 240 and a second magnetic induction sensor 273 connected to a supporting component 210 for illustration. For example, see... Figure 9 The outer wall of the lifting component 240 may be provided with a second receiving groove 242, which is used to receive the second magnetic component 274, making the installation of the second magnetic component 274 more convenient. In some examples, the second magnetic induction sensor 273 can be disposed on the support base 211, thereby simplifying the structure of the support component 210. In other examples, see... Figure 15 and Figure 17 The carrier component 210 may include a carrier circuit board 212, which may include a second carrier circuit board 2122. A second magnetic induction sensor 273 is connected to the second carrier circuit board 2122 and can be electrically connected to a control component via the second carrier circuit board 2122. For example, the second magnetic induction sensor 273 can be surface-mounted onto the second carrier circuit board 2122. The second carrier circuit board 2122 can be positioned opposite and spaced from the lifting component 240 to prevent mutual wear between the lifting component 240 and the second carrier circuit board 2122 during lifting. The second magnetic induction sensor 273 can be located on the side of the second carrier circuit board 2122 facing the second magnetic component 274, and the second magnetic component 274 can be located on the side of the lifting component 240 facing the second magnetic induction sensor 273, thereby reducing the influence of the second carrier circuit board 2122 and the lifting component 240 on the magnetic field induction between the second magnetic component 274 and the second magnetic induction sensor 273. The second carrier circuit board 2122 can be an FPC or a PCB. The second support circuit board 2122 is connected to stationary structural components such as the first cover, rear cover 120, or middle frame 130 to provide support for the second support circuit board 2122. The first support circuit board 2121 and the second support circuit board 2122 can be connected, thereby simplifying the connection between the first support circuit board 2121, the second support circuit board 2122 and the control components. Alternatively, the first support circuit board 2121 and the second support circuit board 2122 can be independent and connected to the control components separately.

[0182] For example, see Figure 17 and Figure 18The lifting device may further include a second magnetic isolator 276, which is used to reduce interference from external magnetic fields on the second magnetic sensor 273. For example, the second magnetic isolator 276 can be a metal part or other structural part that can isolate magnetic fields. In an embodiment where the second magnetic sensor 273 is connected to the side of the second support circuit board 2122 facing the second magnetic element 274, the second magnetic isolator 276 can be located on the side of the second support circuit board 2122 away from the second magnetic element 274, thereby preventing interference from external magnetic fields on the side of the second support circuit board 2122 away from the second magnetic element 274 on the second magnetic sensor 273. The second support circuit board 2122 can be connected to the first cover, the rear cover 120, or the middle frame 130, etc., through the second magnetic isolator 276. The second magnetic isolator 276 can also enhance the mechanical strength of the second carrier circuit board 2122. The second magnetic isolator 276 can be connected to the second carrier circuit board 2122 before the second magnetic induction sensor 273, thereby facilitating the subsequent installation of the second magnetic induction sensor 273 and improving the fixing strength of the second magnetic induction sensor 273, preventing the second magnetic induction sensor 273 from detaching during drops, compression, or impacts. For example, the second magnetic isolator 276 can be connected to the second carrier circuit board 2122 by bonding, welding, or other methods.

[0183] Among them, see Figure 19 The first magnetic induction sensor 271, the first magnetic component 272, the second magnetic induction sensor 273, the second magnetic component 274, and the storage chip can jointly form a position detection module 300a. Through the cooperation of the position detection module 300a and the control component, the position of the lifting component 240 and the rotating component 230 and whether there is jamming can be determined.

[0184] The first driving component provided in the embodiments of this application will be described below.

[0185] The first drive assembly may include, but is not limited to, electric, pneumatic, hydraulic, worm gear, gear, electromagnetic, electro-hydraulic, pneumatic-hydraulic, and electromagnetic-hydraulic methods. The second drive assembly is similar and will not be described further.

[0186] The first drive assembly can be located on the outside of the rotating member 230, thereby enabling the rotating member 230 to be smaller in size, which is beneficial for the miniaturization of the camera device 200. See also Figure 21 and Figure 22 At least a portion of the first drive assembly facing the lifting member 240 is covered by a drive cover 295 to provide support and protection for that portion of the first drive assembly. For example, the drive cover 295 can be fixed to the support base 211 by means of screws, adhesive, welding, etc.

[0187] See Figure 18The first driving component may include a driving element 293, which drives the rotating element 230 to rotate. The driving element 293 may be, but is not limited to, a micro motor. The driving element 293 may include a driving element body 2931 and a driving shaft 2932, with the driving shaft 2932 rotatably connected to the driving element body 2931. See also... Figure 23 and Figure 24 The drive shaft 2932 includes a first shaft end 2932a and a second shaft end, which are opposite to each other. The drive shaft 2932 is inserted into the drive body 2931. The first shaft end 2932a extends out from the drive body 2931 and cooperates with the rotating member 230.

[0188] In some embodiments, see Figure 5 and Figure 6 The extension direction of the drive shaft 2932 of the drive member 293 can be perpendicular to the Z direction (located in the XY plane). The drive member 293 is placed horizontally on the support base 211, thereby reducing the thickness of the camera device 200. At this time, a first transmission member can be provided on the drive shaft 2932 of the drive member 293. The first transmission member can be a worm gear 296. The first drive assembly can include a second transmission member that cooperates with the worm gear 296. The second transmission member can include a worm wheel 291. The worm gear 296 drives the worm wheel 291 to rotate in the XY plane. The second transmission member can include a first gear and a second gear 2922. The first gear is coaxially arranged with the worm wheel 291 and rotates synchronously. The outer periphery of the rotating member 230 can be provided with a toothed structure 233. The second gear 2922 meshes with both the first gear and the toothed structure 233. The drive member 293 sequentially drives the worm gear 296, the worm wheel 291, the first gear, the second gear 2922, and the toothed structure 233 to rotate, thereby driving the rotating member 230 to rotate. In other examples, the first gear can mesh with the tooth structure 233 to drive the rotating member 230 to rotate, thus eliminating the need for a second gear 2922, and the structure of the first drive assembly is simpler.

[0189] In other examples, the second transmission component may further include a third gear 2923, which may be coaxially arranged with the second gear 2922 and mesh with the first gear in the XY plane. The first gear is connected to the second gear 2922 via the third gear 2923; alternatively, the third gear 2923 may mesh with both the first gear and the second gear 2922. Exemplarily, the number of third gears 2923 may be at least one. When there are multiple third gears 2923, the multiple third gears 2923 may mesh with each other in the XY plane, or the multiple third gears 2923 may be partially or completely coaxially arranged. The dimensions of the aforementioned gears may be the same, partially different, or completely different.

[0190] By cooperating with the worm gear 291 and the worm 296, the rotation of the drive shaft 2932 can be reversed to the rotation of the worm gear 291 in the XY plane. By cooperating with multiple gears (first gear, second gear 2922 and third gear 2923), the high-speed, low-torque rotation of the drive shaft 2932 can be transformed into a low-speed, high-torque rotation.

[0191] In some embodiments, the extension direction of the drive shaft 2932 of the drive member 293 can be the Z direction ( Figure 7 The drive unit 293 is vertically placed on the support base 211. The drive shaft 2932 of the drive unit 293 ( Figure 18 A first transmission component is coaxially arranged on the drive assembly 293. This first transmission component can be a drive gear, which meshes with the tooth structure 233 to drive the rotating component 230 to rotate. In other examples, the first drive assembly may include a second transmission component linked to the first transmission component. The second transmission component may include a first gear, which meshes with both the drive gear and the tooth structure 233 in the XY plane. The drive assembly 293 sequentially drives the drive gear, the first gear, and the tooth structure 233 to rotate. In other examples, the second transmission component may include a second gear 2922, which is coaxially arranged with the first gear and rotates synchronously. The first gear meshes with the drive gear, and the second gear 2922 meshes with the tooth structure 233; alternatively, the first gear meshes with both the second gear 2922 and the drive gear in the XY plane, and the second gear 2922 meshes with the tooth structure 233. In other examples, the second transmission component may also include a third gear 2923, whose arrangement is similar to that of the worm gear 296 and worm wheel 291, and will not be described further.

[0192] The aforementioned worm gear 291 and any one or more of the plurality of gears (first gear, second gear 2922, and third gear 2923) can be rotatably connected to the bearing base 211, for example, see [link to relevant documentation]. Figure 7 Multiple gears can be rotatably connected to the support base 211 via gear shaft 297. One end of gear shaft 297 is connected to drive cover 295, and the other end of gear shaft 297 is connected to support base 211. See, for example... Figure 23The drive member 293 may further include an anti-slip member 299, which includes a connected elastic portion 2992 and a fixed portion 2991. The fixed portion 2991 is connected to the side of the drive member body 2931 away from the first shaft end 2932a. The second shaft end can extend from the side of the drive member body 2931 away from the first shaft end 2932a, and the elastic portion 2992 abuts against the second shaft end. For example, the elastic portion 2992 abuts against the side of the second shaft end away from the drive member body 2931. In an embodiment where a worm 296 is provided on the drive shaft 2932, when the worm 296 drives the worm wheel 291 to rotate, the worm wheel 291 applies a reaction force along the axial direction of the worm 296 (equivalent to the axial direction of the drive shaft 2932) to the worm 296. This reaction force can easily cause the drive shaft 2932 to slip along the axial direction of the worm 296. The elastic part 2992 abuts against the second shaft end, and applies an elastic force to the second shaft end, thereby alleviating the axial movement of the drive shaft 2932 along the worm gear 296, and preventing the drive shaft 2932 from squeezing the internal structural components of the drive body 2931 and causing jamming. In addition, the anti-axial movement member 299 can also protect the second shaft end.

[0193] For example, see Figure 24 The first shaft end 2932a can be inserted into the first transmission component (worm gear 296 or drive gear) along the axial direction of the drive shaft 2932, and the first shaft end 2932a and the first transmission component can be interference-fitted. Alternatively, the first shaft end 2932a and the first transmission component can be welded together. Alternatively, the first shaft end 2932a and the first transmission component can be integrally formed, thereby making the connection between the first transmission component and the first shaft end 2932a more stable. When the first shaft end 2932a and the first transmission component are two independent structural components, the first transmission component needs to be assembled onto the first shaft end 2932a, which can easily lead to deformation or misalignment of the first transmission component. As a result, when the drive shaft 2932 rotates at high speed, the first transmission component is prone to lateral movement and swaying perpendicular to the drive shaft 2932, which in turn leads to a loss of transmission efficiency and an increase in noise between the first and second transmission components.

[0194] The first driving component may include a driving circuit board 298, which is electrically connected to a control element configured to control the opening or closing of the first driving component. The driving circuit board 298 may be a flexible circuit board, and may be connected to at least one of a first carrier circuit board 2121 and a second carrier circuit board 2122. Alternatively, the driving circuit board 298, the first carrier circuit board 2121, and the second carrier circuit board 2122 may be independent and each connected to the control element. The first driving component can be electrically connected to a driving chip, a power chip, and a battery 150 sequentially via the driving circuit board 298. The driving chip and the power chip may be disposed on the main circuit board 140, or the driving chip and the power chip may be disposed on a separate sub-circuit board 213 independent of the main circuit board 140. Figure 18 On the lifting device, the sub-circuit board 213 can be installed, and the sub-circuit board 213 can be connected to the support base 211. The sub-circuit board 213 can be located on the side of the support circuit board 212 facing the lifting member 240. The sub-circuit board 213 is also electrically connected to the drive circuit board 298.

[0195] Among them, see Figure 19 The drive chip, power chip, and drive component 293 together form the power module 300b; the first transmission component and the second transmission component together form the transmission module 300c; and the rotating component 230, the lifting component 240, and the top protective cover 281 together form the lifting module 300d. The power module 300b converts the electrical energy of the battery 150 into mechanical energy, providing a power source for the movement of the transmission module 300c and the lifting module 300d. The power chip's function is to boost the battery 150 voltage (typically 3.5V-4.5V) to the drive chip's operating voltage (typically 5V-7V) through a DC-DC boost converter. The drive chip's function is to convert the DC voltage provided by the power chip into a pulse-width modulation (PWM) pulse voltage required by the drive component 293 through a DC-DC power converter. The function of the drive component 293 is to convert electrical energy into mechanical energy under the drive of PWM pulse voltage, causing the drive shaft 2932 of the drive component 293 to rotate at high speed. The working process of the first drive component driving the lifting component 240 to rise and fall can be as follows: the controller sends a control command to the drive chip; the drive chip performs power conversion based on the voltage provided by the power chip and outputs PWM pulse voltage; the drive component 293 converts electrical energy into mechanical energy under the action of PWM pulse voltage to drive the first transmission component to rotate, the first transmission component sequentially drives the second transmission component to rotate, and the gear structure 233 to rotate, thereby causing the rotating component 230 to rotate, and the rotating component 230 drives the lifting component 240 to rise and fall.
