Description

Technical Field

[0001] This application relates to the technical field of terminals, and particularly to a lifting mechanism, a camera device, and an electronic device. Background Art

[0002] With the development of technology, the camera functions in consumer electronic products such as mobile phones and tablets are becoming more and more powerful. As a result, the volume of the camera module is also getting larger and larger. Under the condition that electronic devices pursue thinness and lightness, the appearance of the camera area bulges severely, which greatly affects the user experience.

[0003] In related technologies, the camera can be set as a lifting structure. When shooting, part of the structure of the camera extends out of the electronic device to increase the optically available space of the camera and achieve high-quality shooting; when shooting is not required, the above-mentioned structure of the camera retracts into the electronic device to prevent the camera from protruding from the electronic device and affecting the appearance of the electronic device.

[0004] The current lifting structure of the camera mainly uses a motor in cooperation with a lead screw transmission mechanism to drive the camera to move up and down. Since the lifting stroke of the lead screw transmission mechanism is limited by the length of the lead screw, and the length of the lead screw is limited by the size of the camera, the lifting stroke of the lead screw transmission mechanism is small, resulting in limited telephoto shooting function of the camera. Summary of the Invention

[0005] The purpose of the embodiments of this application is to provide a lifting mechanism, a camera device, and an electronic device. The lifting mechanism has a large lifting stroke, which helps to realize the telephoto shooting function of the camera device.

[0006] In a first aspect, an implementation manner of this application provides a lifting mechanism, which is applied to a camera device including a camera module. The lifting mechanism includes a housing, a rotating member, a driving component, a transverse belt, a longitudinal belt, and a decorative member.

[0007] The middle part of the housing has an installation space for installing the camera module. The rotating member is located inside the housing and surrounds the installation space, and the rotating member is rotatably connected to the housing. The driving component is located inside the housing and connected to the rotating member, and the driving component is used to drive the rotating member to rotate.

[0008] The transverse belt is spiral and elastic. The spiral central axis of the transverse belt corresponds to the rotation central axis of the rotating member. A part of the transverse belt is wound around the rotating member, and the other part of the transverse belt is located under the rotating member and received inside the housing. Here, the fact that the transverse belt is elastic mainly means that the structure of the transverse belt is elastic and can deform.

[0009] The longitudinal belt is in a coiled shape and has elasticity, the coiling center axis of the longitudinal belt corresponds to the rotation center axis of the rotating member, a portion of the longitudinal belt is coiled around the rotating member and meshes with the transverse belt, and another portion of the longitudinal belt is located on the outer peripheral side of the rotating member and accommodated in the housing. The longitudinal belt has elasticity mainly means that the structure of the longitudinal belt has elasticity and can be deformed.

[0010] The decorative piece is located on the top side of the housing and covers the installation space, the periphery of the decorative piece is fixedly connected to the longitudinal belt, and the middle part of the decorative piece is a light-transmitting structure. Light can pass through the middle part of the decorative piece and enter the installation space of the housing.

[0011] When the rotating member rotates forward, the horizontal belt and the vertical belt mesh and rise, and the decorative member rises; when the rotating member rotates reversely, the horizontal belt and the vertical belt descend and separate, and the decorative member descends. "Forward rotation" and "reverse rotation" do not strictly limit the corresponding specific rotation directions, and the two are opposite rotation directions. Forward rotation corresponds to the rotation direction of the rotating member that can drive the lifting member to rise, and reverse rotation corresponds to the rotation direction of the rotating member that can drive the lifting member to descend.

[0012] In the implementation of the present application, the lifting mechanism drives the rotating part to rotate through the driving assembly. When the rotating part rotates, the horizontal belt can be lifted or retracted, and at the same time the longitudinal belt is pressed to engage with the horizontal belt or separate from the horizontal belt to achieve the raising or lowering of the decorative part. This can not only meet the purpose of ensuring that the camera module has sufficient optically available space when the decorative part is raised, but also meet the purpose of keeping the overall height of the camera device small when the decorative part is lowered.

[0013] Among them, the lifting member is lifted and lowered through elastic compression and release, so that the lifting stroke of the lifting member is less restricted by the rigid transmission mechanism, so that it has a larger lifting stroke, so that the camera module has a higher optically available space in the extended state of the lifting mechanism, which is conducive to achieving telephoto shooting.

[0014] For example, the transverse and longitudinal bands of the lifting member of the present application can be compressed back into the shell as much as possible when the lifting mechanism is in the retracted state, and can also be fully engaged and lifted when the lifting mechanism is in the extended state. Therefore, the number of turns of the transverse and longitudinal bands of the lifting member has a high degree of freedom in design, and the number of turns of the transverse and longitudinal bands can be designed to be an appropriate number of turns. The lifting member has a high compression ratio, and the lifting stroke of the lifting member can break through the height limitation of the camera device and the lifting mechanism itself, thereby achieving the purpose of large-scale adjustment of the lifting stroke, increasing the optically available space of the camera module, reducing the protrusion of the appearance of the camera device of the electronic device, and solving the problems of the existing lifting mechanism having too small a stroke and insufficient telephoto shooting capability.

[0015] Among them, the lifting and lowering movements of the lifting parts and decorative parts of the lifting mechanism are completely decoupled from the camera module, so the camera module is not affected by the lifting and lowering movement accuracy of the lifting mechanism, thereby ensuring better shooting quality.

[0016] In some possible implementation manners, the rotating member includes a rotating cylinder, a plurality of engagement groups, and a guide rail. The rotating cylinder is rotatably connected to the housing.

[0017] The plurality of engagement groups are arranged at intervals on the outer peripheral side of the rotating cylinder and are all fixedly connected to the rotating cylinder. Each engagement group includes a setscrew column and an engagement column. The setscrew column protrudes from the outer side surface of the rotating cylinder. The engagement column is disposed opposite to the setscrew column and forms an engagement gap with the setscrew column. The cross belt and the longitudinal belt pass through the engagement gap and are engaged in the engagement gap.

[0018] The guide rail is fixed to the outer side surface of the rotating cylinder and is spiral. The guide rail is separated into multiple segments by the setscrew columns of the plurality of engagement groups. A part of the cross belt is installed on the guide rail along the extending direction of the guide rail, and the cross belt is slidably connected to the guide rail.

[0019] Among them, the setscrew column can be strip-shaped, and the length extending direction of the setscrew column can be parallel to the axial direction of the rotating cylinder, that is, parallel to the central axis of the rotating cylinder. Among them, the setscrew column and the rotating cylinder can be an integrally formed structural member to make the connection between the two more reliable. Or, the setscrew column can also be fixed to the rotating cylinder by an assembly method, such as welding, bonding, clamping, etc. Among them, the setscrew column can be made of a material with a certain hardness, such as metal or plastic and other materials.

[0020] Among them, the engagement column can be strip-shaped, and the length extending direction of the engagement column is parallel to the length extending direction of the setscrew column. At this time, the engagement gap between the engagement column and the setscrew column can also be arranged in a direction parallel to the axial direction of the rotating cylinder. Among them, the engagement column can be made of a material with a certain hardness, such as metal or plastic and other materials.

[0021] In the implementation manner of the present application, through the structural design of the rotating member and the lifting member and the design of the cooperation structure between the two, a set of spiral guiding structure and engagement structure with a small volume is formed. Through the spiral guiding structure, the lifting member of the elastic member can be lifted in a small space, and through the engagement structure, the cross belt and the longitudinal belt of the lifting member can be closely matched together, improving the movement stability of the lifting mechanism.

[0022] In some possible implementation manners, the setscrew column abuts against the cross belt, and a gap is formed between the cross belt and the outer side surface of the rotating cylinder.

[0023] In this implementation manner, by abutting the setscrew column against the cross belt, a gap can be formed between the cross belt and the outer side surface of the rotating cylinder. The cross belt contacts the surface of the setscrew columns of the plurality of engagement groups and does not contact the outer side surface of the rotating cylinder, thereby reducing the contact area between the cross belt and the rotating member, reducing the friction force between the two when the cross belt moves relative to the rotating member, thereby reducing the frictional loss between the rotating member and the cross belt, and also being beneficial to reducing the power consumption of the lifting mechanism.

[0024] In some possible implementation manners, the guide rail includes two convex strips. Both of the two convex strips are spiral and are arranged oppositely. A guiding groove is formed between the two convex strips, and the cross-strip part is located in the guiding groove. At this time, the guide rail is composed of two convex strips, with a simple structure, a small volume, and easy processing.

[0025] Wherein, at the bottom end and the top end of the guide rail, chamfers are provided on one side of the two convex strips close to the guiding groove to expand the inlet and outlet of the guiding groove, facilitating the entry and exit of other structural members into and out of the guiding groove.

[0026] In some possible implementation manners, the guide rail and the rotating cylinder are integrally formed structural members. At this time, the connection between the guide rail and the rotating cylinder is more stable, and it is beneficial to reduce the structural volume.

[0027] Wherein, the guide rail can be made of a material with a certain hardness, such as materials like metal or plastic, to better achieve the guiding function.

[0028] In some possible implementation manners, a wear-resistant layer is provided on the surface of the guide rail in contact with the cross-strip and / or the surface of the cross-strip in contact with the guide rail. Among them, the wear resistance of the wear-resistant layer can be higher than the wear resistance of the main body of the guide rail and the wear resistance of the main body of the cross-strip. Among them, the surface of the guide rail in contact with the cross-strip can be located on the wall surface of the guiding groove of the guide rail; the surface of the cross-strip in contact with the guide rail can be located on the outer surface of the connecting part of the cross-strip.

[0029] In this implementation manner, by setting a wear-resistant layer at the friction position in at least one of the guide rail and the cross-strip, the frictional loss between the guide rail and the cross-strip can be reduced, which is beneficial to improving the reliability of the lifting mechanism.

[0030] In some possible implementation manners, a wear-resistant layer is provided on one or more of the surface of the top screw column facing the meshing column, the surface of the meshing column facing the top screw column, the surface of the longitudinal strip in contact with the top screw column, the surface of the longitudinal strip in contact with the cross-strip, and the surface of the cross-strip in contact with the longitudinal strip.

[0031] In this implementation manner, by setting a wear-resistant layer at least at one of the friction positions between the top screw column and the longitudinal strip, between the meshing column and the longitudinal strip, and between the cross-strip and the longitudinal strip, the frictional loss between the rotating member and the lifting member can be reduced to improve the reliability of the lifting mechanism.

[0032] In some possible implementation manners, the wear-resistant layer is a diamond-like carbon layer or a metal nitriding layer or a metal sulfiding layer.

[0033] In some possible implementation manners, the axial dimension of the cross-sectional shape of the cross-strip is smaller than the radial dimension of the cross-strip. At this time, the cross-strip is more likely to deform axially. The axial dimension of the cross-sectional shape of the longitudinal strip is larger than the radial dimension of the longitudinal strip. At this time, the longitudinal strip is more likely to deform radially.

[0034] The transverse belt comprises a connecting portion and a tooth portion, the tooth portion is fixed to the outer end surface of the connecting portion, and the connecting portion is installed on the guide rail.

[0035] The longitudinal belt is provided with a first hole group and a second hole group, the first hole group is located at the top of the longitudinal belt, and the second hole group is located at the bottom of the longitudinal belt. The first hole group and the second hole group both include a plurality of through holes arranged at intervals along the extension direction of the longitudinal belt.

[0036] In the meshing section of the transverse belt and the longitudinal belt, the first section and the second section of the longitudinal belt are adjacent in the axial direction of the longitudinal belt, the bottom of the first section overlaps the top of the second section, and the teeth of the transverse belt pass through the second hole group of the first section and the first hole group of the second section.

[0037] In this implementation, in the meshing section between the transverse belt and the longitudinal belt, since the two adjacent circles of the transverse belt and the longitudinal belt are meshed, the two adjacent circles of the transverse belt can be supported by the same circle of the longitudinal belt to maintain the relative position relationship between the two adjacent circles of the transverse belt, so that the retaining structure of the meshing section between the transverse belt and the longitudinal belt in the axial direction of the lifting member is stable so as to have a stable height.

[0038] In some possible implementations, the engagement column abuts against the longitudinal belt. At this time, through the cooperation of the engagement column and the top screw column, the longitudinal belt and the transverse belt can be meshed and connected, and a stable connection relationship can be maintained to avoid radial movement between the longitudinal belt and the transverse belt, thereby improving the reliability of the lifting member and the lifting mechanism. Among them, when the rotor rotates clockwise, the engagement column drives the longitudinal belt to move radially toward the direction close to the rotating member, retract inward, and make the longitudinal belt buckle on the transverse belt and mesh tightly with the transverse belt.

[0039] In some possible implementations, the meshing column is provided with a recessed avoidance groove, and the avoidance groove is used to avoid the horizontal belt. The avoidance groove of the meshing column can be recessed from the surface of the meshing column facing the top screw column to the inside of the meshing column. The avoidance grooves of the meshing columns of multiple meshing groups can be set at different heights along the axial direction of the rotating drum.

[0040] In this implementation, the engagement column can maintain a supporting relationship with the longitudinal belt, and also allow the teeth of the transverse belt to have a larger height through a recessed avoidance groove. For example, the height of the teeth of the transverse belt can exceed the thickness of the longitudinal belt to better maintain a stable engagement relationship with the longitudinal belt.

[0041] In some possible implementations, the rotating member further includes a connecting ring and a plurality of connecting posts. The connecting ring is located on the outer circumference of the rotating drum, the tops of the engagement posts of the plurality of engagement groups are fixed to the connecting ring, and the plurality of connecting posts are connected one by one between the bottom of the engagement post and the top screw post.

[0042] Wherein, a concave-convex matching structure is formed between the corresponding connecting column and the top screw column. For example, the end of the connecting column connected to the top screw column can be provided with a groove, and the top screw column is inserted into the groove to form a match.

[0043] In this implementation, the meshing post is fixedly connected to the rotating cylinder through the connecting post and the set screw post. The relative positional relationship between the connecting post and the set screw post is stable, so that the relative positional relationship between the meshing post and the set screw post is stable and not prone to displacement.

[0044] In some possible implementations, the rotating member further includes a turntable. The turntable surrounds the outer peripheral side of the rotating cylinder and is located at the bottom side of the guide rail. The turntable is fixedly connected to the rotating cylinder, and the driving assembly is connected to the turntable.

[0045] In this implementation, the driving assembly drives the rotating member to rotate by driving the turntable to rotate.

[0046] In some possible implementations, the driving assembly may include a driving member and a transmission assembly. The driving member can transmit power and motion through the transmission assembly.

[0047] In this implementation, the driving assembly can change the direction and speed of the output power through the specific structural design of the transmission assembly, so as to better drive the structure to be driven of the lifting mechanism. For example, the transmission assembly can be used as a speed reduction mechanism to reduce the high rotation speed of the motor to a suitable rotation speed and then output it.

[0048] In some possible implementations, a first storage cavity is formed between the turntable and the housing. The first storage cavity is located at the bottom side of the turntable. The turntable has an access hole, and the access hole communicates with the first storage cavity. The cross belt passes through the access hole and part of it is located in the first storage cavity.

[0049] In this implementation, by setting the first storage cavity, the cross belt can be compressed back into the first storage cavity as much as possible when the lifting mechanism is in the retracted state, so that the height of the lifting mechanism in the retracted state is smaller. In addition, the degree of freedom in the design of the number of turns of the cross belt is also higher.

[0050] Among them, the last turn (i.e., the bottommost turn) of the cross belt located in the first storage cavity can be fixedly connected to the housing, so that during the lifting process of the cross belt, the main movement is along the axial direction of the rotating member, and there is little circumferential displacement on the rotating member. Therefore, when the rotating member rotates, it can better drive the cross belt to perform axial lifting, so as to ensure the accuracy and reliability of the driving action.

[0051] In some possible implementations, a second storage cavity is formed between the rotating member and the housing. The second storage cavity surrounds the outer peripheral side of the rotating member. The longitudinal belt passes through the space between the meshing posts of two adjacent meshing groups and part of it is located in the second storage cavity.

[0052] In this implementation, by setting the second storage cavity, the longitudinal belt can be compressed back into the second storage cavity as much as possible when the lifting mechanism is in the retracted state, so that the width of the lifting mechanism in the retracted state is smaller. In addition, the degree of freedom in the design of the number of turns of the longitudinal belt is also higher.

[0053] Among them, the last circle of the longitudinal belt located in the second storage cavity (that is, the outermost circle) can be fixedly connected to the shell, so that when the longitudinal belt is retracted or expanded, the main movement is carried out along the radial direction of the rotating part, and there is less displacement in the circumferential direction of the rotating part. As a result, when the rotating part rotates, it can better drive the longitudinal belt to retract or expand, so as to ensure the accuracy and reliability of the driving action.

[0054] In some possible implementations, the plurality of meshing groups include a first meshing group and a second meshing group arranged adjacent to each other. In the circumferential direction of the rotating member, the first meshing group corresponds to the inlet and outlet holes, the second meshing group is staggered from the inlet and outlet holes, and the bottom end of the guide rail is located between the inlet and outlet holes and the second meshing group. That is, the first meshing group is located in the space above the inlet and outlet holes, the second meshing group is staggered from the space above the inlet and outlet holes, and the bottom end of the guide rail is located close to the inlet and outlet holes.

[0055] In this implementation, by setting the relative positional relationship between the first meshing group, the second meshing group, the inlet and outlet holes and the bottom end of the guide rail, the horizontal belt rises from the first storage cavity, passes through the inlet and outlet holes of the turntable, enters the guide rail from the bottom end of the guide rail, and then meshes with the longitudinal belt at the second meshing group. When the longitudinal belt is in the process of descending, the horizontal belt leaves the second meshing group, detaches from the guide rail, enters the first storage cavity through the inlet and outlet holes of the turntable, and is completely separated from the longitudinal belt at the first meshing group.

[0056] The longitudinal belt can pass through the space between the engagement posts of the first engagement group and the engagement posts of the second engagement group to extend out of or enter the second storage cavity.

[0057] In this implementation, when the driving assembly drives the rotating member to rotate forward, the guide rail drives the transverse belt to rise, a part of the longitudinal belt engages with the transverse belt, and rises with the transverse belt, and the lifting mechanism can be changed from the retracted state to the extended state. Part of the transverse belt can rise upward from the first storage cavity, pass through the inlet and outlet hole of the turntable, and enter the guide rail from the bottom end of the guide rail of the rotating member, and part of the longitudinal belt can shrink inward from the second storage cavity, pass between the meshing column of the first meshing group and the meshing column of the second meshing group, enter the rotating member, and mesh with the transverse belt in the meshing gap of the second meshing group of the rotating member, and the meshing part of the transverse belt and the longitudinal belt rises to the top side of the guide rail.

[0058] When the driving assembly drives the rotating member to rotate in the opposite direction, the guide rail drives the transverse belt to descend, and a part of the longitudinal belt can descend with the transverse belt and detach from the transverse belt, and the lifting mechanism can be changed from the extended state to the retracted state. Among them, the meshing section of the transverse belt and the longitudinal belt can descend, and between the first meshing group and the second meshing group, a part of the transverse belt detaches from the guide rail, passes through the inlet and outlet hole of the rotating disk, and enters the first storage cavity, and a part of the longitudinal belt detaches from the transverse belt, and then expands outward, passes between the meshing column of the first meshing group and the meshing column of the second meshing group, and enters the second storage cavity, and the transverse belt and the longitudinal belt have been separated at the position corresponding to the second meshing group.

[0059] In some possible implementation manners, the housing includes a base and an upper shell.

[0060] The base includes a bottom wall, an inner side wall, a first outer side wall, and a first connecting wall. A first through hole is provided in the middle of the bottom wall. The bottom end of the inner side wall is connected to the inner peripheral edge of the bottom wall. The bottom end of the first outer side wall is connected to the outer peripheral edge of the bottom wall. The first connecting wall surrounds the outer peripheral side of the first outer side wall and is connected to the top end of the first outer side wall. A first storage cavity surrounds the outer peripheral side of the inner side wall. The base further has a sunk groove, which is located between the inner side wall and the first outer side wall and on the top side of the first storage cavity. The sunk groove communicates with the first storage cavity.

[0061] The upper shell includes a top wall, a second outer side wall, a second connecting wall, and a partition wall. A second through hole is provided in the middle of the top wall. The top end of the second outer side wall is connected to the outer peripheral edge of the top wall. The second connecting wall surrounds the outer peripheral side of the second outer side wall and is connected to the bottom end of the second outer side wall. The partition wall is located inside the second outer side wall and is connected to the bottom end of the second outer side wall. A second storage cavity is located between the top wall and the partition wall.

[0062] The second connecting wall is fixedly connected to the first connecting wall. The partition wall is located on the top side of the sunk groove. The turntable is installed in the sunk groove.

[0063] In some possible implementation manners, the turntable has a counterweight hole or a counterweight block, and the center of gravity of the rotating member is located on the rotation center axis of the rotating member.

[0064] In this implementation manner, by providing a counterweight hole and / or a counterweight block on the turntable, the center of gravity of the rotating member is located on the rotation center axis of the rotating member, which can reduce the risk of the rotating member rotating when the lifting mechanism drops, and is beneficial to ensuring the reliability of the mechanism. In addition, the center of gravity of the rotating member being located on the rotation center axis of the rotating member also makes the rotating member not overweight when rotating, or the overweight situation is very slight, thereby avoiding the problem of large wear in a local area of the rotating member (during the friction process, the wear at a certain position in the structural member is usually significantly greater than that at a lighter position), which is beneficial to extending the service life of the rotating member and improving the reliability of the rotating member and the lifting mechanism.

[0065] In some possible implementation manners, the decorative member includes a fixing ring and a light-transmitting sheet. The light-transmitting sheet is fixed to the inner peripheral edge of the fixing ring and covers the inner through hole of the fixing ring. The outer peripheral edge of the fixing ring is connected to a longitudinal strip. For example, the light-transmitting sheet can be a light-transmitting lens. Among them, the longitudinal strip can be embedded in the fixing groove of the fixing ring to increase the connection stability and firmness between the longitudinal strip and the decorative member.

[0066] In this implementation manner, the decorative member is located on the top side of the housing, and the light-transmitting sheet of the decorative member is arranged corresponding to the installation space of the housing, so that the light on the top side of the lifting mechanism can pass through the light-transmitting sheet and enter the installation space.

[0067] In some possible implementation manners, the lifting mechanism further includes a first waterproof member. The top end of the first waterproof member is hermetically connected to the periphery of the decorative member, and the other end of the first waterproof member is used for hermetically connecting to the camera module. The first waterproof member is annular and can expand and contract along the axial direction of the rotating member.

[0068] Wherein, when the lifting mechanism is in the retracted state, the first waterproof member is in a compressed state, and the first waterproof member is in a cylindrical structure with obvious wrinkles; when the lifting mechanism is in the extended state, the first waterproof member is in an unfolded state, and the first waterproof member can be in a smooth cylindrical structure or a cylindrical structure with slight wrinkles. The height of the first waterproof member in the unfolded state is greater than the height of the first waterproof member in the compressed state.

[0069] In this implementation manner, by hermetically connecting the periphery of the decorative member and the camera module with the first waterproof member, the risk of external water vapor, dust, etc. entering the light incident surface of the camera module can be reduced, so as to improve the waterproof and dustproof performance of the camera device, which is beneficial to ensuring the shooting quality of the camera device.

[0070] In some possible implementation manners, the longitudinal strip passes through the top wall of the housing, and the top wall of the housing has an inner side facing the longitudinal strip; the lifting mechanism further includes a second waterproof member. The second waterproof member is annular, and the second waterproof member is fixed to the inner side of the top wall of the housing and abuts against the longitudinal strip.

[0071] In this implementation manner, by sealing the gap between the longitudinal strip and the housing with the second waterproof member, the risk of external water vapor, dust, etc. entering the inside of the lifting structure can be reduced, so as to improve the reliability of the lifting mechanism and the camera device.

[0072] In some possible implementation manners, the height of the lifting mechanism is less than the width of the lifting mechanism. Wherein, the height of the lifting mechanism refers to its height in the retracted state, and the width of the lifting mechanism refers to its height in the retracted state.

[0073] In this implementation manner, the height of the lifting mechanism is small and the width is large. When the lifting mechanism is applied to an electronic device, the height of the lifting mechanism corresponds to the thickness direction of the electronic device, and the width of the lifting mechanism can correspond to the width direction or the length direction of the electronic device. Therefore, the lifting mechanism and the camera device can be better applied to thin electronic devices.

[0074] In some possible implementation manners, the ratio of the lifting stroke of the decorative member to the height of the lifting mechanism is greater than or equal to 0.8, or greater than or equal to 1. Wherein, the height of the lifting mechanism refers to its height in the retracted state.

[0075] In this implementation, by setting the number of turns of the horizontal belt and the vertical belt of the lifting member, the lifting member has a high compression ratio and can flexibly adjust the lifting stroke of the lifting member, so that the lifting stroke is close to or exceeds the height of the lifting mechanism, enabling the lifting mechanism to better achieve a large lifting stroke.

[0076] In a second aspect, an implementation of the present application also provides a camera device, including a camera module and the lifting mechanism according to any one of the above, and the camera module is fixedly connected to the lifting mechanism.

[0077] In the present application, when the lifting mechanism is in the retracted state, the camera device can have a small height, facilitating installation in an electronic device; when the lifting mechanism is in the extended state, the camera device can have sufficient optical available space, facilitating the implementation of the telephoto shooting function.

[0078] In a third aspect, an implementation of the present application also provides an electronic device, including a housing and the above camera device. The camera device is installed in the housing, and the decorative member of the lifting mechanism of the camera device is exposed relative to the housing.

[0079] In this implementation, the decorative member of the lifting mechanism can be lifted through a through hole. When the lifting mechanism is in the retracted state, the decorative member is close to the housing, and the overall height of the lifting mechanism and the camera device is small. The camera device is easy to be installed in the electronic device, and the protrusion height on the appearance surface of the electronic device can be reduced, which is beneficial to the appearance design and thickness design of the electronic device.

[0080] When the lifting mechanism is in the extended state, the decorative member rises and moves away from the housing, and an optical available space for the camera module is formed below the decorative member. At this time, the camera module can extend and retract the lens through the optical available space to achieve zooming, enabling the camera module to have higher shooting quality and better realizing the telephoto shooting function.

Of course, other types of electronic devices may also adopt a similar structure, which will not be elaborated hereinafter.

[0124] It can be understood that Figure 1A and Figure 1B only schematically show some components included in the electronic device 100. The actual shapes, actual sizes, actual positions, and actual structures of these components are not limited by Figure 1A and Figure 1B , and the electronic device 100 may also include more or fewer components compared to Figure 1A and Figure 1B .

[0125] In some embodiments, the electronic device 100 may include a screen 10, a housing 20, and a camera device 30. Among them, the screen 10 is used to display images, videos, etc. The screen 10 may include a light-transmitting panel 101 and a display screen 102. The light-transmitting panel 101 and the display screen 102 are stacked and fixedly connected. The light-transmitting panel 101 is mainly used to protect the display screen 102 and prevent dust. The material of the light-transmitting panel 101 includes but is not limited to glass. The display screen 102 may be a flexible display screen or a rigid display screen. For example, the display screen 102 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a quantum dot light emitting diodes (QLED) display screen, a liquid crystal display (LCD), etc.

[0126] Exemplarily, the housing 20 is used to protect the internal electronic components of the electronic device 100. The housing 20 may include a cover plate 201, a frame 202, and a camera decorative piece 203. The cover plate 201 is located on the side of the display screen 102 away from the light-transmitting panel 101 and is stacked with the light-transmitting panel 101 and the display screen 102. The frame 202 is fixed to the cover plate 201. Exemplarily, the frame 202 may be fixedly connected to the cover plate 201 by adhesive. The frame 202 may also be an integrally formed structure with the cover plate 201, that is, the frame 202 and the cover plate 201 are a whole structure. The frame 202 is located between the cover plate 201 and the light-transmitting panel 101. The light-transmitting panel 101 may be fixedly adhered to the frame 202. The light-transmitting panel 101, the cover plate 201, and the frame 202 enclose an internal accommodation space of the electronic device 100. The internal accommodation space houses the display screen 102. Among them, the cover plate 201 may be made of materials such as metal, plastic, and glass. The cover plate 201 may be a plate body made of a single material, or a plate body structure including multiple materials and spliced by multiple plates. Among them, an installation opening 2011 is provided on the cover plate 201, and the camera decorative piece 203 covers and is fixed at the installation opening 2011.

[0127] Exemplarily, the camera device 30 is used to take photos / videos. For example, the camera device 30 is installed on the housing 20, and most or all of it is located in the internal accommodation space of the electronic device 100. Among them, the camera device 30 can be used as a rear camera module. For example, the light incident surface of the camera device 30 faces the camera decorative member 203. The camera decorative member 203 is used to protect the camera device 30.

[0128] In some embodiments, the camera decorative member 203 protrudes to the side of the cover plate 201 away from the light-transmitting panel 101. In this way, the camera decorative member 203 can increase the installation space of the camera device 30 in the thickness direction of the electronic device 100. In other embodiments, the camera decorative member 203 can also be flush with the cover plate 201 or recessed into the internal accommodation space of the electronic device 100.

[0129] Among them, a through hole 204 is provided on the camera decorative member 203. The through hole 204 allows scene light to enter the light incident surface of the camera device 30. Part of the structure of the camera device 30 can be exposed through the through hole 204. In some other embodiments, the electronic device 100 may not include the camera decorative member 203 either. At this time, no installation opening is provided on the cover plate 201, and a through hole 204 is provided on the cover plate 201. Part of the structure of the camera device 30 can be exposed through the through hole 204, and the through hole 204 allows the scene to enter the light incident surface of the camera device 30.

[0130] In other embodiments, the camera device 30 can also be used as a front camera module. For example, the light incident surface of the camera device 30 faces the light-transmitting panel 101. An optical path avoidance hole is provided on the display screen 102. The optical path avoidance hole allows the scene light to pass through the light-transmitting panel 101 and then enter the light incident surface of the camera device 30. In other embodiments, the electronic device 100 may further include one or more other camera modules (not shown in the figure), and the embodiments of the present application do not make strict limitations on this.

[0131] In some embodiments, as Figure 1B shown, the electronic device 100 further includes a circuit board 50 and an image processor 60. The circuit board 50 and the image processor 60 are located in the internal accommodation space of the electronic device 100. The image processor 60 is fixed to the circuit board 50 and electrically connected to the circuit board 50. The image processor 60 is communicatively connected to the camera device 30. The image processor 60 is used to obtain image data from the camera device 30 and process the image data. Among them, the communication connection between the camera device 30 and the image processor 60 can include data transmission through electrical connection methods such as wiring, or data transmission can be achieved through coupling and other means. It can be understood that the camera device 30 and the image processor 60 can also be communicatively connected through other means capable of realizing data transmission.

[0132] In some embodiments, the electronic device 100 may further include an analog-to-digital converter (also referred to as an A / D converter, not shown in the figure). The analog-to-digital converter is connected between the camera device 30 and the image processor 60. The analog-to-digital converter is used to convert the signal generated by the camera device 30 into a digital image signal and transmit it to the image processor 60, and then the image processor 60 processes the digital image signal, and finally the image or video is displayed through the screen 10.

[0133] In some embodiments, the electronic device 100 may further include a memory (not shown in the figure), and the memory is communicatively connected to the image processor 60. After the image processor 60 processes the image digital signal, the image is transmitted to the memory, so that the image can be retrieved from the memory at any time when it is necessary to view the image later and displayed on the screen 10. In some embodiments, the image processor 60 also compresses the processed image digital signal and then stores it in the memory to save memory space.

[0134] In some embodiments, the electronic device 100 may further include a driving chip (not shown in the figure), and the driving chip is communicatively connected to the camera device 30 and can be used to drive at least part of the structure in the camera device 30 to move.

[0135] In some other embodiments, the electronic device 100 may not include the screen 10.

[0136] It can be understood that Figure 1A and Figure 1B the installation position of the camera device 30 of the electronic device 100 shown in the embodiments is only illustrative, and the present application does not strictly limit the installation position of the camera device 30. In some other embodiments, the camera device 30 may also be installed at other positions of the electronic device 100. For example, the camera device 30 may be installed in the upper middle or upper right corner of the back of the electronic device 100. In some other embodiments, the electronic device 100 may include a terminal body and an auxiliary component that can rotate, move or be detached relative to the terminal body, and the camera device 30 may also be provided on the auxiliary component.

[0137] Please refer to Figures 2A to 3B , Figure 2A which Figure 1B is a schematic structural diagram of the camera device 30 in some embodiments as shown, Figure 2B which Figure 2A is a schematic cross-sectional structural diagram of the camera device 30 shown along the A-A section, Figure 3A which Figure 2A is a schematic structural diagram of the camera device 30 in another usage state as shown, Figure 3B which Figure 3ASchematic cross-sectional structure diagram of the camera device 30 shown in the cut along B-B.

[0138] In the following text, for the convenience of description, it is defined that the camera device 30 has a width direction X, a length direction Y, and a height direction Z, and the above three are perpendicular to each other in pairs. Among them, when the camera device 30 is installed in the electronic device 100, the height direction Z of the camera device 30 can be parallel to the thickness direction of the electronic device 100, that is, perpendicular to the cover plate 201 and the screen 10 of the electronic device 100. Among them, the light incident side (that is, the side for light entry) of the camera device 30 is the top side of the camera device 30, and the bottom side of the camera device 30 is opposite to the top side. When the camera device 30 is a rear camera, the side of the camera device 30 close to the cover plate 201 is its top side, and the side close to the screen 10 is its bottom side. In the relevant descriptions in the following text, for the camera device 30 and its components and structures, the part close to the light incident side is "top", and the part far from the light incident side is "bottom". In other embodiments, the coordinate system setting of the camera device 30 can be flexibly set according to specific actual needs.

[0139] In some embodiments, the camera device 30 includes a lifting mechanism (lifter) 1 and a camera module 2. Exemplarily, the lifting mechanism 1 may include a housing 11, a lifting member 12, and a decorative member 13. Among them, the middle part of the housing 11 has an installation space 11a, and the installation space 11a penetrates from the top side of the housing 11 to the bottom side of the housing 11. Among them, the lifting member 12 can be installed in the housing 11, the lifting member 12 is a movable member, and at least part of the lifting member 12 can rise or fall relative to the housing 11 to extend out of or retract into the housing 11. The decorative member 13 is located on the top side of the housing 11 and covers the installation space 11a, and the decorative member 13 is fixedly connected to the lifting member 12. At this time, the decorative member 13 can rise or fall with the lifting member 12. Among them, the middle part of the decorative member 13 is a light-transmitting structure, so that external light can pass through the decorative member 13 and enter the installation space 11a.

[0140] Among them, the installation space 11a of the housing 11 is used to install the camera module 2. Exemplarily, the camera module 2 can be fixedly connected to the housing 11 to fixedly connect to the lifting mechanism 1. The camera module 2 can be at least partially located in the installation space 11a. For example, a part of the camera module 2 can be located in the installation space 11a to be located inside the lifting mechanism 1, and another part of the camera module 2 can be located at the bottom side of the lifting mechanism 1; or, the camera module 2 is entirely located in the installation space 11a. Among them, the lens of the camera module 2 is located in the installation space 11a and is arranged facing the middle part of the decorative member 13, and the camera module 2 captures the light passing through the decorative member 13 for shooting.

[0141] In this embodiment, the lifting mechanism 1 has a retracted state and an extended state. As Figure 2A andFigure 2B As shown in the figure, when the lifting mechanism 1 is in the retracted state, the lifting member 12 is received inside the housing 11, and the decorative member 13 is close to the top of the housing 11 (for example, it can contact the top of the housing 11 or form a small gap with the top of the housing 11). The overall height of the lifting mechanism 1 and the camera device 30 is small, the camera device 30 is easy to be installed in the electronic device 100, and the protrusion height on the appearance surface of the electronic device 100 can be reduced, which is beneficial to the appearance design and thickness design of the electronic device 100.

[0142] As Figure 3A and Figure 3B shown in the figure, when the lifting mechanism 1 is in the extended state, a part of the lifting member 12 extends out of the housing 11, the decorative member 13 rises and moves away from the top of the housing 11, and an activity space 11b communicating with the installation space 11a is formed below the decorative member 13. The activity space 11b forms an optical available space for the camera module 2. At this time, the camera module 2 can telescopically adjust the lens through the activity space 11b to achieve zooming, so that the camera module 2 has higher shooting quality and can better implement the telephoto shooting function.

[0143] Exemplarily, with reference to Figures 1A to 2A , when the camera device 30 is installed in the electronic device 100, the top of the housing 11 of the lifting mechanism 1 faces the outer shell 20 (such as the camera decorative member 203 or the cover plate 201), and the decorative member 13 of the lifting mechanism 1 can be exposed relative to the outer shell 20, for example, it can be exposed through the through hole 204. At this time, the decorative member 13 can be lifted through the through hole 204. In some examples, when the lifting mechanism 1 is in the retracted state, the decorative member 13 can be at least partially located in the through hole 204, so that the decorative member 13 and the outer shell 20 share the thickness space of the electronic device 100, which is beneficial to the thinning of the electronic device 100.

[0144] In some embodiments, the lifting member 12 can be an elastic member, and the lifting member 12 realizes lifting through elastic compression and release, so that the lifting stroke of the lifting member 12 is less restricted by the rigid transmission mechanism, and has a larger lifting stroke, so that the camera module 2 has a higher optical available space in the extended state of the lifting mechanism 1, which is beneficial to realizing telephoto shooting.

[0145] Please refer to Figure 2A and Figure 4 , Figure 4 is Figure 2A the exploded structural schematic diagram of the camera device 30 shown in the figure.

[0146] In some embodiments, the lifting mechanism 1 is a modular structure, and the camera module 2 is also a modular structure. The two are assembled to form the camera device 30. In this embodiment, the lifting mechanism 1 provides an installation space 11a and a moving space 11b for the camera module 2. The camera module 2 is connected to the housing 11 (a stationary part) of the lifting mechanism 1. The lifting movement of the lifting member 12 and the decorative member 13 of the lifting mechanism 1 is completely decoupled from that of the camera module 2. Therefore, the camera module 2 is not affected by the lifting movement accuracy of the lifting mechanism 1, and thus a better shooting quality can be ensured.

[0147] The implementation structure of the lifting mechanism 1 will be described by way of example below.

[0148] Please refer to Figure 5 , Figure 5 which Figure 4 is the exploded structural schematic diagram of the lifting mechanism 1 shown.

[0149] In some embodiments, the lifting mechanism 1 includes the above-mentioned housing 11, lifting member 12 and decorative member 13, and may further include a rotating member 14, a driving assembly 15, a waterproof assembly 16 and a fastening assembly 17. Among them, the housing 11 may include a base 111 and an upper shell 112; the lifting member 12 may include a horizontal belt 121 and a vertical belt 122; the waterproof assembly 16 may include a first waterproof member 161 and a second waterproof member 162; the fastening assembly 17 may include a plurality of fasteners 171.

An inner space is formed inside the upper shell 112, and the inner space 112a of the upper shell 112 penetrates from the top side to the bottom side of the upper shell 112. Among them, the base 111 and the upper shell 112 are fixed to each other to form the housing 11, and the inner space 111a of the base 111 and the inner space 112a of the upper shell 112 together form the above-mentioned installation space 11a of the housing 11.

[0152] Exemplarily, the base 111 and the upper shell 112 can be fixedly connected by a plurality of fasteners 171 of the fastening assembly 17. Among them, the base 111 and the upper shell 112 can both be provided with fastening holes to facilitate the fixation by the fasteners 171. The fasteners 171 can be structures such as screws, bolts, rivets, etc. In some other embodiments, the base 111 and the upper shell 112 can also be fixed by connection methods such as snap connection, bonding, welding, etc. The embodiments of the present application do not strictly limit the connection method and connection structure between the base 111 and the upper shell 112.

Among them, the bottom end of the inner side wall 1112 is connected to the inner peripheral edge of the bottom wall 1111, and the inner side wall 1112 stands relative to the bottom wall 1111 and has a certain height. At this time, the inner side wall 1112 surrounds the first through hole, and the inner side wall 1112 surrounds a space communicating with the first through hole, and this space and the first through hole together form the inner space 111a of the base 111.

[0154] In some examples, the inner side wall 1112 can be provided with one or more notches 111b, and the notches 111b communicate with the inner space 111a of the base 111. When there are multiple notches 111b, the multiple notches 111b can be arranged at intervals along the circumferential direction of the inner side wall 1112. At this time, the notches 111b penetrate the inner surface of the inner side wall 1112, and can reduce the area of the inner surface of the inner side wall 1112.

[0155] Among them, the bottom end of the first outer side wall 1113 is connected to the outer peripheral edge of the bottom wall 1111, and the first outer side wall 1113 stands relative to the bottom wall 1111 and has a certain height.

[0156] Exemplarily, the base 111 may have a first storage cavity 111c and a sunk groove 111d. Among them, the first storage cavity 111c surrounds the outer peripheral side of the inner side wall 1112, and the first storage cavity 111c has an opening facing the top side of the base 111. Among them, the first storage cavity 111c may be jointly formed by the bottom wall 1111 and the inner side wall 1112, or the first storage cavity 111c may be formed by the depression of the bottom wall 1111.

Among them, the base 111 may also include a first protrusion 1115 and a second protrusion 1116.

That is, a plurality of meshing groups 142 are arranged along the circumferential direction of the rotating cylinder 141 on the outside of the rotating cylinder 141. Among them, the number of meshing groups 142 can be more than two, such as two, three, four, five, etc. In this embodiment of the present application, four are taken as an example for illustration. For example, a plurality of meshing groups 142 can include a first meshing group 142a, a second meshing group 142b, a third meshing group 142c, and a fourth meshing group 142d arranged in sequence along the circumferential direction of the rotating cylinder 141.

Among them, the engagement post 1422 can be strip-shaped, and the length extension direction of the engagement post 1422 is parallel to the length extension direction of the set screw post 1421. At this time, the engagement gap 1423 between the engagement post 1422 and the set screw post 1421 can also be arranged in the direction parallel to the axial direction of the rotating cylinder 141. Among them, the surface of the engagement post 1422 facing the set screw post 1421 can be a flat surface, or can also be an arc surface, or can also be a spliced curved surface of a flat surface and an arc surface. Among them, the engagement post 1422 can be made of a material with a certain hardness, such as metal or plastic and other materials.

[0176] Among them, the engagement post 1422 is provided with a recessed avoidance groove 1424, and the avoidance groove 1424 can be recessed from the surface of the engagement post 1422 facing the set screw post 1421 into the engagement post 1422. Among them, the avoidance grooves 1424 of the engagement posts 1422 of multiple engagement groups 142 can be arranged at different heights along the axial direction of the rotating cylinder 141. For example, the heights of the avoidance grooves of the engagement posts of the second engagement group 142b, the third engagement group 142c, the fourth engagement group 142d, and the first engagement group 142a increase in sequence, and the connection lines of the above several avoidance grooves in the circumferential direction of the rotating shaft are spiral.

[0177] Among them, in addition to the above-mentioned avoidance groove (referred to as the first avoidance groove), the engaging posts of the second engaging group 142b may be provided with another avoidance groove (referred to as the second avoidance groove), and the second avoidance groove is located on the top side of the first avoidance groove.

[0178] Exemplarily, the connecting ring 143 is located on the outer peripheral side of the rotating cylinder 141, and the connecting ring 143 is arranged at an interval from the rotating cylinder 141. The tops of the engaging posts 1422 of the plurality of engaging groups 142 are all fixed to the connecting ring 143. Among them, the engaging posts 1422 of the plurality of engaging groups 142 and the connecting ring 143 may be integrally formed structural members, or may form an integral structure through an assembly method.

[0179] Among them, the number of the connecting posts 144 is the same as the number of the engaging posts 1422. The plurality of connecting posts 144 are correspondingly connected between the bottoms of the engaging posts 1422 and the top screw posts 1421. Among them, a concave-convex fitting structure may be formed between the corresponding connecting posts 144 and the top screw posts 1421. For example, a groove may be provided at the end of the connecting post 144 connecting the top screw post 1421, and the top screw post 1421 is snapped into the groove to form a fit. At this time, the engaging post 1422 is fixedly connected to the rotating cylinder 141 through the connecting post 144 and the top screw post 1421, and the relative position relationship between the connecting post 144 and the top screw post 1421 is stable, so that the relative position relationship between the engaging post 1422 and the top screw post 1421 is stable and not prone to displacement. Among them, the corresponding engaging post 1422 and the connecting post 144 may be integrally formed structural members, or may form an integral structure through an assembly method.

[0180] Exemplarily, the guide rail 145 is fixed to the outer side surface of the rotating cylinder 141 and is spiral. The guide rail 145 is separated into multiple segments by the top screw posts 1421 of the plurality of engaging groups 142. That is, the guide rail 145 is disconnected at the position corresponding to the top screw post 1421 to form multiple segments of structures. The multiple segments of structures as a whole are still spiral, and each segment of structure is a part of the spiral. Among them, the avoidance groove 1424 of the engaging post 1422 is arranged corresponding to the disconnection position of two adjacent segments of structures. Among them, the spiral center line 145o of the guide rail 145 may coincide with the central axis 141o of the rotating cylinder 141 to be parallel to the axial direction of the rotating cylinder 141. Among them, the guide rail 145 may be a right-handed spiral structure or a left-handed spiral structure. In the embodiment of the present application, the guide rail 145 is shown as a right-handed spiral structure.

[0181] Among them, the guide rail 145 and the rotating cylinder 141 can be integrally formed structural members, so that the connection between the guide rail 145 and the rotating cylinder 141 is more stable and is beneficial to reducing the structural volume. In some other embodiments, the guide rail 145 can also be fixed to the rotating cylinder 141 by other means such as welding, clamping, bonding, etc. Among them, the guide rail 145 can be made of materials with a certain hardness, such as metals or plastics, etc., to better achieve the guiding function.

[0182] Among them, the guide rail 145 can include two convex strips 1451. The two convex strips 1451 are both spiral and are arranged oppositely. A guiding groove 1452 is formed between the two convex strips 1451. At this time, the guiding groove 1452 is also spiral, and the spiral shape of the guiding groove 1452 corresponds to the spiral shape of the guide rail 145. Among them, the guide rail 145 is composed of two convex strips 1451, with a simple structure, small volume, and easy to process.

[0183] Among them, the guide rail 145 has a bottom end 145a and a top end 145b. In the axial direction of the rotating cylinder 141, the top end 145b of the guide rail 145 is higher than the bottom end 145a of the guide rail 145. Among them, at the bottom end 145a and the top end 145b of the guide rail 145, chamfers are provided on the side of the two convex strips 1451 close to the guiding groove 1452 to expand the inlet and outlet of the guiding groove 1452, facilitating other structural members to enter and leave the guiding groove 1452.

[0184] Exemplarily, the turntable 146 surrounds the outer peripheral side of the rotating cylinder 141 and is located at the bottom side of the guide rail 145. The turntable 146 is fixedly connected to the rotating cylinder 141. Among them, the turntable 146 and the rotating cylinder 141 can be integrally formed structural members, so that the connection between the guide rail 145 and the rotating cylinder 141 is more stable. In some other embodiments, the turntable 146 can also be fixed to the rotating cylinder 141 by other means such as welding, clamping, bonding, etc. Among them, the turntable 146 can be made of materials with a certain hardness, such as metals or plastics, etc.

[0185] Among them, a tooth portion 1461 is provided on the outer peripheral edge of the turntable 146. The multiple teeth of the tooth portion 1461 can be continuously arranged in a surrounding manner. External structural members can drive the turntable 146 to rotate by engaging with the tooth portion 1461 of the turntable 146, and then drive the rotating member 14 to rotate.

[0186] Among them, the turntable 146 has an access hole 1462. The access hole 1462 penetrates through the turntable 146 along the axial direction of the rotating cylinder 141, and the access hole 1462 communicates the top-side space and the bottom-side space of the turntable 146. Among them, the access hole 1462 can be provided on the side of the turntable 146 close to the rotating cylinder 141, and the access hole 1462 can be arc-shaped and partially surround the rotating cylinder 141.

[0187] For example, for the first meshing group 142a and the second meshing group 142b arranged adjacent to each other in the plurality of meshing groups 142, in the circumferential direction of the rotating member 14, the first meshing group 142a corresponds to the inlet and outlet hole 1462, the second meshing group 142b is staggered from the inlet and outlet hole 1462, and the bottom end 145a of the guide rail 145 is located between the inlet and outlet hole 1462 and the second meshing group 142b. At this time, the bottom end 145a of the guide rail 145 is disposed close to the inlet and outlet hole 1462.

[0188] The rotating disk 146 may also have a counterweight hole 1463, and the counterweight hole 1463 is used to adjust the center of gravity of the rotating member 14. For example, the counterweight hole 1463 may be spaced apart from the inlet and outlet hole 1462, and the counterweight hole 1463 may be arc-shaped. In other embodiments, the rotating disk 146 may also have a counterweight block (not shown in the figure), and the counterweight block is used to adjust the center of gravity of the rotating member 14. Alternatively, the rotating disk 146 may also adjust the center of gravity of the rotating member 14 through the cooperation of the counterweight hole 1463 and the counterweight block.

[0189] In some examples, the rotating drum 141, the plurality of top screw posts 1421, and the rotating disk 146 can be integrally formed into an inner rotor, and the connecting ring 143, the plurality of meshing posts 1422, and the plurality of connecting posts 144 can be integrally formed into an outer rotor, and the outer rotor is fixedly connected to the inner rotor to form the rotating member 14. The outer rotor and the inner rotor can be fixedly connected by welding. In other embodiments, the outer rotor and the inner rotor can also be fixedly connected by other means such as clamping and bonding, which is not strictly limited in the embodiments of the present application.

[0190] Please refer to Figures 12A to 12C , Figure 12A yes Figure 10 The base 111 and the drive assembly 15 are shown with Figure 11A The schematic diagram of the structure of the rotating member 14 after assembly is shown. Figure 12B yes Figure 12A The schematic diagram of the structure shown at another angle, Figure 12C yes Figure 5 The schematic diagram of the internal structure of the housing 11, the driving assembly 15 and the rotating member 14 after being assembled is shown.

[0191] In some embodiments, the rotating member 14 is located in the housing 11 and surrounds the installation space 11a, and the rotating member 14 is rotatably connected to the housing 11. For example, the rotating cylinder 141 of the rotating member 14 can be sleeved on the outer peripheral side of the inner side wall 1112 of the base 111, and the rotating cylinder 141 is rotatably connected to the housing 11. Among them, the rotating disk 146 of the rotating member 14 can be installed in the sink 111d of the base 111, and the rotating disk 146 is also rotatably connected to the housing 11.

[0192] Among them, the rotating member 14 can rotate relative to the housing 11 about the rotation center axis 14o. The rotation center axis 14o of the rotating member 14 can be parallel to the axial direction of the rotating member 14 and can coincide with the central axis 141o of the rotating cylinder 141. Among them, since the inner side wall 1112 is provided with a notch 111b, the contact area between the rotating cylinder 141 and the inner side wall 1112 can be reduced. Thus, while ensuring the connection reliability, the friction area during the relative movement of the two can also be reduced, thereby reducing the frictional force.

[0193] Among them, the driving assembly 15 is connected to the rotating member 14 and is used to drive the rotating member 14 to rotate. For example, the second tooth portion 15232 of the second tower tooth 1523 can be at least partially located in the sinking groove 111d of the base 111 to engage with the turntable 146. When the driving member 151 works, the turntable 146 is driven to rotate through the second tooth portion 15232 of the second tower tooth 1523, so as to drive the rotating member 14 to rotate.

[0194] Among them, as Figure 12C shown, the first storage cavity 111c is located between the turntable 146 and the housing 11 and is located on the bottom side of the turntable 146. The access hole 1462 of the turntable 146 communicates with the first storage cavity 111c. At this time, the first storage cavity 111c can communicate with the space on the top side of the turntable 146 through the access hole 1462 of the turntable 146. Among them, the guide rail 145 and the engagement group 142 of the rotating member 14 are located on the top side of the first storage cavity 111c. Among them, the second storage cavity 112b is located between the rotating member 14 and the housing 11, and the second storage cavity 112b surrounds the outer peripheral side of the rotating member 14. For example, the second storage cavity 112b can be located on the outer peripheral side of the guide rail 145 and the engagement group 142 of the rotating member 14. The connecting ring 143 of the rotating member 14 can be located on the bottom side of the inner peripheral edge of the top wall 1121 of the housing 11, and a gap is formed between the rotating cylinder 141 and the inner side surface of the top wall 1121.

[0195] Please refer to Figure 13 and Figure 14 , Figure 13 which Figure 5 is the schematic structural diagram of the lifting member 12 shown in Figure 14 and Figure 13 is the schematic structural diagram of the lifting member 12 in another use state shown in

[0196] In some embodiments, the cross belt 121 of the lifting member 12 is helical and elastic. Herein, the cross belt 121 being elastic mainly means that the structure of the cross belt 121 is elastic and can deform. Among them, the cross belt 121 has a helical central axis 121o, and the cross belt 121 extends and arranges spirally around the helical central axis 121o. Among them, the cross belt 121 is elastic in the direction parallel to the helical central axis 121o and can deform, stretch and compress in the direction parallel to the helical central axis 121o. Among them, the axial dimension of the cross-sectional shape of the cross belt 121 is smaller than the radial dimension of the cross belt 121. For example, the cross-sectional shape of the cross belt 121 is flat, and the long side of the cross-sectional shape is arranged in the radial direction. The cross-sectional shape of the cross belt 121 is the shape of the cross-section perpendicular to its extending direction. The axial direction of the cross belt 121 is the direction parallel to the helical central axis 121o, and the radial direction of the cross belt 121 is perpendicular to the axial direction of the cross belt 121. At this time, the cross belt 121 is more likely to deform in its axial direction. Among them, the cross belt 121 can be a right-handed helical structure or a left-handed helical structure. In the embodiments of the present application, the cross belt 121 is schematically shown as a right-handed helical structure.

[0197] Among them, the cross belt 121 may include a connecting portion 1211 and a tooth portion 1212, and the tooth portion 1212 is fixed to the outer end surface of the connecting portion 1211. Among them, the connecting portion 1211 of the cross belt 121 forms the main structure of the cross belt 121, surrounds the helical central axis 121o and is helical. The outer end surface of the connecting portion 1211 is arranged facing away from the helical central axis 121o. The tooth portion 1212 of the cross belt 121 includes a plurality of teeth arranged at intervals, and the plurality of teeth surround the helical central axis 121o and are arranged spirally along with the connecting portion 1211. Among them, the shape of the teeth can be rectangular teeth. In some other embodiments, the shape of the teeth can also be trapezoidal, triangular or other shapes, and the embodiments of the present application do not strictly limit this.

[0198] In some embodiments, the longitudinal belt 122 of the lifting member 12 is wound and elastic. Herein, the longitudinal belt 122 being elastic mainly means that the structure of the longitudinal belt 122 is elastic and can deform. Among them, the longitudinal belt 122 has a winding central axis 122o, and the longitudinal belt 122 winds around the winding central axis 122o. Among them, the longitudinal belt 122 is elastic in the direction perpendicular to the winding central axis 122o and can deform, wind inwards and expand outwards in the direction perpendicular to the winding central axis 122o. Among them, the axial dimension of the cross-sectional shape of the longitudinal belt 122 is larger than the radial dimension of the longitudinal belt 122. For example, the cross-sectional shape of the longitudinal belt 122 is narrow and high, and the long side of the cross-sectional shape is arranged in the axial direction. The cross-sectional shape of the longitudinal belt 122 is the shape of the cross-section perpendicular to its extending direction. The axial direction of the longitudinal belt 122 is the direction parallel to the winding central axis 122o, and the radial direction of the longitudinal belt 122 is perpendicular to the axial direction of the longitudinal belt 122. At this time, the longitudinal belt 122 is more likely to deform in its radial direction.

[0199] Among them, the longitudinal strip 122 can also be elastic in a direction parallel to the winding central axis 122o, capable of deforming in a direction parallel to the winding central axis 122o, and performing stretching and compression.

[0200] Among them, the longitudinal strip 122 can be provided with a first hole group 1221 and a second hole group 1222. The first hole group 1221 is located at the top of the longitudinal strip 122, and the second hole group 1222 is located at the bottom of the longitudinal strip 122. Both the first hole group 1221 and the second hole group 1222 include a plurality of through holes arranged at intervals along the extending direction of the longitudinal strip 122. Among them, the through holes of the first hole group 1221 and the through holes of the second hole group 1222 can be arranged opposite to each other or staggeredly arranged in a direction parallel to the winding central axis 122o.

[0201] In some embodiments, a part of the transverse strip 121 meshes with a part of the longitudinal strip 122, and the meshing part (hereinafter referred to as the meshing section) can change. Among them, the lifting member 12 can have a first state and a second state. The first state can correspond to the initial state, and the length of the meshing section between the transverse strip 121 and the longitudinal strip 122 is shorter. The second state can correspond to the fully meshed state, and the length of the meshing section between the transverse strip 121 and the longitudinal strip 122 is longer.

[0202] Among them, both the transverse strip 121 and the longitudinal strip 122 can be divided into a storage section (121a / 122a), a meshing section (121b / 122b), and a transition section (121c / 122c) according to their current assembled forms. The storage section (121a / 122a) is the part in the initial storage state, the meshing section (121b / 122b) is the meshing part, and the transition section (121c / 122c) is the part connecting the storage section (121a / 122a) and the meshing section (121b / 122b). Among them, the topmost section of the transverse strip 121 and the innermost section of the longitudinal strip 122 can always remain in a meshed state, which is the meshing section (121b / 122b). Among them, the bottommost section of the transverse strip 121 and the outermost section of the longitudinal strip 122 can always remain in an undeformed state, which is the storage section (121a / 122a). Among them, the pitch of the meshing section 121b of the transverse strip 121 is greater than the pitch of the storage section 121a of the transverse strip 121. The pitch refers to the axial distance between two adjacent sections of the transverse strip 121 in the axial direction.

[0203] During the process of the lifting member 12 changing from the first state to the second state: the meshing section 121b of the horizontal belt 121 and the meshing section 122b of the vertical belt 122 rise; the transition section 121c of the horizontal belt 121 rises, the transition section 122c of the vertical belt 122 rolls inwards, and gradually meshes with the transition section 121c of the horizontal belt 121. After they are meshed, they are converted into the meshing section (121b / 122b); a part of the storage section 121a of the horizontal belt 121 is converted into the transition section 121c and rises, and a part of the storage section 122a of the vertical belt 122 is converted into the transition section 122c and rolls inwards.

[0204] During the process of the lifting member 12 changing from the second state to the first state: the meshing section 121b of the horizontal belt 121 and the meshing section 122b of the vertical belt 122 descend, and a part of the meshing section 121b of the horizontal belt 121 and a part of the meshing section 122b of the vertical belt 122 are gradually separated and converted into the transition section (121c / 122c); the transition section 121c of the horizontal belt 121 descends and is gradually converted into the storage section 121a, the transition section 122c of the vertical belt 122 expands outwards and is gradually converted into the storage section 122a; the length of the storage section 121a of the horizontal belt 121 becomes longer, and the length of the storage section 122a of the vertical belt 122 becomes longer.

[0205] Exemplarily, as Figure 14 shown, in the meshing section (121b / 122b) of the horizontal belt 121 and the vertical belt 122, the vertical belt 122 may include a first section 1223 and a second section 1224. The first section 1223 and the second section 1224 of the vertical belt 122 are adjacent in the axial direction of the vertical belt 122. The bottom of the first section 1223 overlaps with the top of the second section 1224. The tooth portion 1212 of the horizontal belt 121 passes through the second hole group 1222 of the first section 1223 and the first hole group 1221 of the second section 1224. Among them, the first section 1223 and the second section 1224 of the vertical belt 122 may be respectively one section of the belt body or the entire belt body of two adjacent turns of the belt body of the vertical belt 122, and the first section 1223 and the second section 1224 are arranged in alignment in the axial direction of the vertical belt 122.

[0206] In this embodiment, in the meshing section of the horizontal belt 121 and the vertical belt 122, since the two adjacent turns of the belt body of the horizontal belt 121 and the vertical belt 122 are both meshed, the two adjacent turns of the horizontal belt 121 can be supported by the same turn of the vertical belt 122 to maintain the relative position relationship between the two adjacent turns of the horizontal belt 121, so that the meshing section of the horizontal belt 121 and the vertical belt 122 has a stable structure in the axial direction of the lifting member 12 and has a stable height.

[0207] It can be understood that in some other embodiments, there may also be other assembly structures such as meshing structures and support structures between the horizontal belt 121 and the vertical belt 122 of the lifting member 12, and the embodiments of the present application do not strictly limit this.

[0208] Please refer to Figure 15A and Figure 15B , Figure 15A which Figure 12A is a schematic assembly structure diagram of the structure shown in Figure 13 and the horizontal belt 121 shown in Figure 15B and Figure 15A is a schematic structure diagram of the structure shown in another usage state.

[0209] In some embodiments, the horizontal belt 121 is installed on the rotating member 14 and the housing 11. Exemplarily, a part of the horizontal belt 121 is wound around the rotating member 14, another part of the horizontal belt 121 is located at the bottom side of the rotating member 14 and is received in the housing 11, and the spiral central axis 121o of the horizontal belt 121 can correspond to the rotation central axis 14o of the rotating member 14, and the two can coincide. Among them, when there is a small deviation and non - coincidence between the spiral central axis 121o of the horizontal belt 121 and the rotation central axis 14o of the rotating member 14 due to manufacturing tolerances or assembly tolerances, the two are also considered to be in a coincident state.

[0210] For example, a part of the horizontal belt 121 can be installed on the guide rail 145 of the rotating member 14 along the extension direction of the guide rail 145, and the horizontal belt 121 is slidably connected to the guide rail 145. This part of the structure of the horizontal belt 121 passes through the meshing gap 1423 of the meshing group 142 of the rotating member 14. Among them, the horizontal belt 121 can be partially located in the guide groove 1452 of the guide rail 145 to better cooperate with the guide rail 145. Among them, the connecting portion 1211 of the horizontal belt 121 can be installed on the guide rail 145, and the tooth portion 1212 of the horizontal belt 121 can be arranged facing the meshing column 1422.

[0211] For example, another part of the horizontal belt 121 can pass through the access hole 1462 of the turntable 146 and extend into the first storage cavity 111c located at the bottom side of the rotating member 14. At this time, the horizontal belt 121 passes through the access hole 1462 of the turntable 146 and is partially located in the first storage cavity 111c.

[0212] In this embodiment, when the driving assembly 15 drives the rotating member 14 to rotate, the guide rail 145 rotates and drives the horizontal belt 121 installed on the guide rail 145 to move, so that the horizontal belt 121 moves up and down. For example, when the driving assembly 15 drives the rotating member 14 to rotate clockwise, the guide rail 145 drives the horizontal belt 121 to rise. Among them, a part of the horizontal belt 121 can extend out of the first storage cavity 111c, enter the guide rail 145, and then rise to the top side of the guide rail 145. When the driving assembly 15 drives the rotating member 14 to rotate counterclockwise, the guide rail 145 drives the horizontal belt 121 to descend. Among them, a part of the horizontal belt 121 located on the top side of the guide rail 145 can enter the guide rail 145, then disengage from the guide rail 145, and enter the first storage cavity 111c.

[0213] Please refer toFigures 16A to 16D , Figure 16A is Figure 12A the assembly structure diagram of the structure shown in Figure 13 and the lifting member 12 shown in Figure 16B is Figure 5 the internal structure diagram after the housing 11, the drive assembly 15, the rotating member 14 and the lifting member 12 shown in Figure 16C is Figure 16A the structure diagram of the structure shown in another use state Figure 16D is Figure 16B the structure diagram of the structure shown in another use state

[0214] In some embodiments, the longitudinal belt 122 is installed on the rotating member 14 and the housing 11. Exemplarily, a part of the longitudinal belt 122 is wound around the rotating member 14 and meshes with the transverse belt 121, and another part of the longitudinal belt 122 is located on the outer peripheral side of the rotating member 14 and is received in the housing 11. The winding central axis 122o of the longitudinal belt 122 may correspond to the rotation central axis 14o of the rotating member 14. For example, the longitudinal belt 122 may pass through the meshing gap 1423 of the meshing group 142 and mesh with the transverse belt 121 at the meshing gap 1423. For example, the longitudinal belt 122 may mesh with the transverse belt 121 at the second meshing group 142b. The longitudinal belt 122 also passes through the space between the meshing posts 1422a of the first meshing group 142a and the meshing posts 1422b of the second meshing group 142b, and part of it is located in the second storage cavity 112b.

[0215] In this embodiment, the drive assembly 15 drives the rotating member 14 to rotate, and the rotating member 14 rotates to drive the transverse belt 121 and the longitudinal belt 122 to move, so that the lifting member 12 can be lifted and lowered. Among them, Figure 16A and Figure 16B correspond to the structure when the lifting mechanism 1 is in the retracted state. At this time, the lifting member 12 is in the first state; Figure 16C and Figure 16D correspond to the structure when the lifting mechanism 1 is in the extended state. At this time, the lifting member 12 is in the second state.

[0216] In some examples, when the driving component 15 drives the rotating member 14 to rotate clockwise, the guide rail 145 drives the transverse belt 121 to rise. A part of the longitudinal belt 122 meshes with the transverse belt 121 and rises with the transverse belt 121, and the lifting mechanism 1 can be changed from the retracted state to the extended state. Among them, a part of the transverse belt 121 can rise upward from the first storage cavity 111c, pass through the access hole 1462 of the turntable 146, and enter the guide rail 145 of the rotating member 14. A part of the longitudinal belt 122 can contract inward from the second storage cavity 112b, pass through the space between the engaging posts 1422a of the first engaging group 142a and the engaging posts 1422b of the second engaging group 142b, enter the rotating member 14, and mesh with the transverse belt 121 at the engaging gap 1423 of the engaging group 142 (such as the second engaging group 1422b) of the rotating member 14. The meshing part of the transverse belt 121 and the longitudinal belt 122 rises to the top side of the guide rail 145.

[0217] When the driving component 15 drives the rotating member 14 to rotate counterclockwise, the guide rail 145 drives the transverse belt 121 to descend. A part of the longitudinal belt 122 can descend with the transverse belt 121 and disengage from the transverse belt 121, and the lifting mechanism 1 can be changed from the extended state to the retracted state. Among them, the meshing section of the transverse belt 121 and the longitudinal belt 122 can descend. Between the first engaging group 142a and the second engaging group 142b, a part of the transverse belt 121 disengages from the bottom end of the guide rail 145, passes through the access hole 1462 of the turntable 146, and enters the first storage cavity 111c. A part of the longitudinal belt 122 disengages from the transverse belt 121 and then expands outward, passes through the space between the engaging posts 1422a of the first engaging group 142a and the engaging posts 1422b of the second engaging group 142b, and enters the second storage cavity 112b. The transverse belt 121 and the longitudinal belt 122 have been separated at the position corresponding to the second engaging group 142b.

[0218] Among them, the last turn (i.e., the bottommost turn) of the transverse belt 121 located in the first storage cavity 111c can be fixedly connected to the housing 11, so that during the lifting process of the transverse belt 121, the main movement is along the axial direction of the rotating member 14, and there is little circumferential dislocation on the rotating member 14. Therefore, when the rotating member 14 rotates, it can better drive the transverse belt 121 to perform axial lifting, so as to ensure the accuracy and reliability of the driving action.

[0219] Among them, the last turn (i.e., the outermost turn) of the longitudinal belt 122 located in the second storage cavity 112b can be fixedly connected to the housing 11, so that during the process of the longitudinal belt 122 contracting or expanding outward, the main movement is along the radial direction of the rotating member 14, and there is little circumferential dislocation on the rotating member 14. Therefore, when the rotating member 14 rotates, it can better drive the longitudinal belt 122 to contract or expand outward, so as to ensure the accuracy and reliability of the driving action.

[0220] Please refer toFigure 16B and Figure 17 , Figure 17 is Figure 16A the top view of the structure shown.

[0221] In some embodiments, the set screw post 1421 of the engagement group 142 abuts against the cross belt 121, and a gap is formed between the cross belt 121 and the outer side surface of the rotating cylinder 141. In this embodiment, by abutting the set screw post 1421 against the cross belt 121, a gap can be formed between the cross belt 121 and the outer side surface of the rotating cylinder 141. The cross belt 121 contacts the surfaces of the set screw posts 1421 of multiple engagement groups 142 and does not contact the outer side surface of the rotating cylinder 141, thereby reducing the contact area between the cross belt 121 and the rotating member 14. When the cross belt 121 moves relative to the rotating member 14, the friction between the two is reduced, thereby reducing the frictional loss between the rotating member 14 and the cross belt 121, and also facilitating the reduction of the power consumption of the lifting mechanism 1.

[0222] Among them, the engagement post 1422 abuts against the longitudinal belt 122. At this time, through the cooperation of the engagement post 1422 and the set screw post 1421, the longitudinal belt 122 and the cross belt 121 can be meshed and connected, and a stable connection relationship can be maintained to avoid radial play between the longitudinal belt 122 and the cross belt 121, improving the reliability of the lifting member 12 and the lifting mechanism 1. Among them, when the rotor rotates clockwise, the engagement post 1422 will drive the longitudinal belt 122 to radially move inward from the second storage cavity 112b towards the rotating member 14, and the longitudinal belt 122 will be buckled on the cross belt 121 and tightly meshed with the cross belt 121.

[0223] Among them, during the process of the rotating member 14 driving the lifting member 12 to rise, after the cross belt 121 extends from the first storage cavity 111c and the longitudinal belt 122 extends from the second storage cavity 112b, the two can be meshed at the second engagement group 142b of the rotating member 14, and then sequentially enter the third engagement group 142c and the fourth engagement group 142d to maintain a stable meshing relationship, and the longitudinal belt 122 and the cross belt 121 can rise synchronously.

[0224] In some embodiments, as Figure 16B shown, the relief groove 1424 on the engagement post 1422 is used to avoid the cross belt 121. At this time, the engagement post 1422 can not only maintain the abutting relationship with the longitudinal belt 122, but also through the recessed relief groove 1424, allowing the tooth portion 1212 of the cross belt 121 to have a relatively large height. For example, the height of the tooth portion 1212 of the cross belt 121 can exceed the thickness of the longitudinal belt 122 to better maintain a stable meshing relationship with the longitudinal belt 122.

[0225] In the embodiment of the present application, the lifting mechanism 1 forms a set of spiral guiding structure and meshing structure with a small volume through the structural design of the rotating member 14 and the lifting member 12 and the cooperative structural design of the two. Through the spiral guiding structure, the lifting member 12 of the elastic member can be lifted and lowered in a small space, and through the meshing structure, the cross belt 121 and the longitudinal belt 122 of the lifting member 12 can be closely matched together, improving the movement stability of the lifting mechanism 1.

[0226] In the embodiment of the present application, during the lifting process of the lifting mechanism 1, mutual friction occurs between the lifting member 12 and the rotating member 14. The lifting mechanism 1 improves the wear resistance of the lifting mechanism 1 and enhances the reliability of the lifting mechanism 1 by providing a wear-resistant layer at the friction position.

[0227] Exemplarily, the surface of the guide rail 145 contacting the cross belt 121 and / or the surface of the cross belt 121 contacting the guide rail 145 may be provided with a wear-resistant layer (not shown in the figure). Among them, the wear resistance of the wear-resistant layer may be higher than the wear resistance of the main body of the guide rail 145 and the main body of the cross belt 121. Among them, the surface of the guide rail 145 contacting the cross belt 121 may be located on the wall surface of the guide groove 1452 of the guide rail 145; the surface of the cross belt 121 contacting the guide rail 145 may be located on the outer surface of the connecting portion 1211 of the cross belt 121.

[0228] In this embodiment, by providing a wear-resistant layer at the friction position in at least one of the guide rail 145 and the cross belt 121, the friction loss between the guide rail 145 and the cross belt 121 can be reduced, which is beneficial to improving the reliability of the lifting mechanism 1.

[0229] Exemplarily, one or more of the surface of the set screw column 1421 facing the meshing column 1422, the surface of the meshing column 1422 facing the set screw column 1421, the surface of the longitudinal belt 122 contacting the set screw column 1421, the surface of the longitudinal belt 122 contacting the cross belt 121, and the surface of the cross belt 121 contacting the longitudinal belt 122 may be provided with a wear-resistant layer. The wear resistance of the above wear-resistant layer may be higher than the wear resistance of the structural main body.

[0230] In this embodiment, by providing a wear-resistant layer at least at one of the friction positions between the set screw column 1421 and the longitudinal belt 122, between the meshing column 1422 and the longitudinal belt 122, and between the cross belt 121 and the longitudinal belt 122, the friction loss between the rotating member 14 and the lifting member 12 can be reduced to improve the reliability of the lifting mechanism 1.

[0231] Exemplarily, the above wear-resistant layer may be a diamond-like carbon layer. Among them, the wear-resistant layer can be formed by thin-film deposition technology. Alternatively, the wear-resistant layer can also be a metal nitriding layer or a metal sulfiding layer. Among them, the wear-resistant layer can be formed by performing a nitriding process or a sulfiding process on the surface layer of a structural member made of a metal material. In other embodiments, the wear-resistant layer can also have other implementation structures or materials, and the embodiments of the present application do not strictly limit this.

[0232] In the embodiments of the present application, the lifting member 12 can also be provided with a counterweight hole 1463 (which can be referred to Figure 11A ) and / or a counterweight block on the turntable 146 of the rotating member 14, so that the center of gravity of the rotating member 14 is located on the rotation center axis 14o of the rotating member 14.

[0233] In this embodiment, by providing a counterweight hole 1463 and / or a counterweight block on the turntable 146, the center of gravity of the rotating member 14 is located on the rotation center axis 14o of the rotating member 14, which can reduce the risk of the rotating member 14 rotating when the lifting mechanism 1 drops, and is beneficial to ensuring the reliability of the mechanism. In addition, the center of gravity of the rotating member 14 being located on the rotation center axis 14o of the rotating member 14 also makes the rotating member 14 not overweight when rotating, or the overweight situation is very slight, thus avoiding the problem of large wear in a local area of the rotating member 14 (during the friction process, usually the wear at the heavy position in the structural member is significantly greater than that at the light position), which is beneficial to extending the service life of the rotating member 14 and improving the reliability of the rotating member 14 and the lifting mechanism 1.

[0234] Please refer to Figure 18 , Figure 18 is Figure 5 the structural schematic diagram of the decorative member 13 shown.

[0235] In some embodiments, the decorative member 13 includes a fixing ring 131 and a light-transmitting sheet 132. Among them, a through hole 1311 is formed inside the fixing ring 131. The fixing ring 131 has a sinking groove 1312 with an opening facing the top side, and the sinking groove 1312 surrounds the through hole and is communicated with the through hole 1311. The fixing ring 131 may also have a recessed groove 1313 and a fixing groove 1314 with openings facing the bottom side. The recessed groove 1313 surrounds the through hole 1311 and is spaced from the through hole 1311. The recessed groove 1313 may also surround the sinking groove 1312. The fixing groove 1314 surrounds the recessed groove 1313.

[0236] Among them, the light-transmitting sheet 132 can be made of a light-transmitting material. For example, the light-transmitting sheet 132 can be a light-transmitting lens. The light-transmitting sheet 132 can be fixed to the inner peripheral edge of the fixing ring 131 and cover the inner through-hole of the fixing ring 131 (i.e., the through-hole 1311). For example, the light-transmitting sheet 132 can be partially located in the sinking groove 1312 of the fixing ring 131, and the light-transmitting sheet 132 can be fixedly connected to the bottom wall surface of the sinking groove 1312 through the adhesive layer 133.

[0237] Please refer to Figure 19A , Figure 19A which Figure 2A is a schematic cross-sectional structure diagram of the lifting mechanism 1 of the camera device 30 shown in FIG. along the A-A section.

[0238] In some embodiments, the decorative member 13 is located on the top side of the housing 11, and the peripheral edge of the decorative member 13 is fixedly connected to the longitudinal strip 122. For example, the decorative member 13 can be connected to the longitudinal strip 122 through the outer peripheral edge of the fixing ring 131. The longitudinal strip 122 can be embedded in the fixing groove 1314 of the fixing ring 131 to increase the connection stability and firmness between the longitudinal strip 122 and the decorative member 13. Among them, the longitudinal strip 122 and the decorative member 13 can be fixedly connected to each other by gluing or other connection methods.

[0239] In this embodiment, the decorative member 13 is located on the top side of the housing 11, and the light-transmitting sheet 132 of the decorative member 13 is arranged corresponding to the installation space 11a of the housing 11, so that the light on the top side of the lifting mechanism 1 can pass through the light-transmitting sheet 132 and enter the installation space 11a.

[0240] Please refer to Figure 19A and Figure 19B , Figure 19B which Figure 19A is a schematic structural diagram of the lifting mechanism 1 in another use state shown in FIG.

[0241] In some embodiments, in the lifting mechanism 1, when the driving component 15 drives the rotating member 14 to rotate forward, the horizontal strip 121 meshes with the longitudinal strip 122 and rises, and the decorative member 13 rises. When the driving component 15 drives the rotating member 14 to rotate reversely, the horizontal strip 121 and the longitudinal strip 122 descend and separate, and the decorative member 13 descends. Among them, the above "forward rotation" and "reverse rotation" do not strictly limit their corresponding specific rotation directions. The two are opposite rotation directions. The forward rotation corresponds to the rotation direction of the rotating member 14 that can drive the lifting member 12 to rise, and the reverse rotation corresponds to the rotation direction of the rotating member 14 that can drive the lifting member 12 to descend.

[0242] In the embodiment of the present application, the lifting mechanism 1 drives the rotating member 14 to rotate through the driving assembly 15. When the rotating member 14 rotates, the transverse belt 121 can be lifted or retracted, and at the same time the longitudinal belt 122 is pressed to engage with the transverse belt 121 or separate from the transverse belt 121 to achieve the raising or lowering of the decorative member 13, thereby satisfying the purpose of ensuring that the camera module 2 has sufficient optically available space when the decorative member 13 is raised, and satisfying the purpose of keeping the overall height of the camera device 30 small when the decorative member 13 is lowered.

[0243] In addition, the transverse band 121 and the longitudinal band 122 of the lifting member 12 of the present application can not only be compressed as much as possible into the first storage cavity 111c and the second storage cavity 112b in the shell 11 when the lifting mechanism 1 is in the retracted state, but can also be fully engaged and lifted when the lifting mechanism 1 is in the extended state. Therefore, the number of turns of the transverse band 121 and the longitudinal band 122 of the lifting member 12 has a high degree of freedom in design, and the number of turns of the transverse band 121 and the longitudinal band 122 can be designed to be an appropriate number of turns. The lifting member 12 has a high compression ratio, and the lifting stroke of the lifting member 12 can break through the height limitation of the camera device 30 and the lifting mechanism 1 itself, so as to achieve the purpose of large-scale adjustment of the lifting stroke, thereby increasing the optically available space of the camera module 2, reducing the protrusion of the appearance of the camera device 30 of the electronic device 100, and solving the problems of the existing lifting mechanism 1 having too small a stroke and insufficient telephoto shooting capability.

[0244] In addition, by further designing the matching structure between the rotating part 14 and the lifting part 12, the lifting part 12 is driven by the rotation of the rotating part 14, so that the horizontal belt 121 and the longitudinal belt 122 of the lifting part 12 can be smoothly engaged, raised, retracted and stored, thereby realizing a large-stroke lifting in a limited space.

[0245] In the embodiment of the present application, the lifting mechanism 1 is also designed to be waterproof to improve the waterproof performance of the lifting mechanism 1, the camera device 30 and the electronic device 100.

[0246] In some embodiments, such as Figure 19A and Figure 19B As shown, the top end of the first waterproof member 161 of the waterproof assembly 16 can be sealed and connected to the periphery of the decorative member 13, and the other end of the first waterproof member 161 is used to seal and connect the camera module 2 (see Figure 2B ). The first waterproof member 161 is annular and can be extended and retracted along the axial direction of the rotating member 14. When the lifting mechanism 1 is in the retracted state, the first waterproof member 161 is in a compressed state, and the first waterproof member 161 is a cylindrical structure with obvious wrinkles; when the lifting mechanism 1 is in the extended state, the first waterproof member 161 is in an expanded state, and the first waterproof member 161 can be a smooth cylindrical structure, or a cylindrical structure with slight wrinkles. The height of the first waterproof member 161 in the expanded state is greater than the height of the first waterproof member 161 in the compressed state.

[0247] Among them, the first waterproof member 161 can be made of materials such as rubber. The waterproof assembly 16 can further include a first fixing ring 163 and a second fixing ring 164. The first fixing ring 163 is fixed to one end of the first waterproof member 161, and the second fixing ring 164 is fixed to the other end of the first waterproof member 161. The first fixing ring 163 and the second fixing ring 164 can be made of metal materials, such as steel and the like. In some examples, the first fixing ring 163, the first waterproof member 161 and the second fixing ring 164 can be an integrally formed structural member, for example, they can be formed into a single structural member by insert injection molding process. Or, in other examples, the first fixing ring 163, the first waterproof member 161 and the second fixing ring 164 can also be assembled to form an integral structure.

[0248] Among them, the first fixing ring 163 and the decorative member 13 can be fixed by dotting glue, or fixed and connected by other means. The second fixing ring 164 and the camera module 2 (see Figure 2B ) can be fixed by dotting glue, or fixed and connected by other means.

[0249] In this embodiment, by sealing and connecting the periphery of the decorative member 13 and the camera module 2 with the first waterproof member 161, the risk of external water vapor, dust, etc. entering the light incident surface of the camera module 2 can be reduced, so as to improve the waterproof and dustproof performance of the camera device 30, which is beneficial to ensuring the shooting quality of the camera device 30.

[0250] In some embodiments, as Figure 19A and Figure 19B shown, the longitudinal strip 122 of the lifting member 12 passes through the top wall 1121 of the housing 11, and the top wall 1121 of the housing 11 has an inner side facing the longitudinal strip 122. The second waterproof member 162 of the waterproof assembly 16 is annular, and the second waterproof member 162 is fixed to the inner side of the top wall 1121 of the housing 11 and abuts against the longitudinal strip 122.

[0251] Among them, the second waterproof member 162 can be made of materials such as rubber. The second waterproof member 162 can be fixed to the housing 11 by injection molding, or the second waterproof member 162 can also be fixed to the housing 11 by bonding or other means. The embodiments of the present application do not strictly limit this.

[0252] In this embodiment, by sealing the gap between the longitudinal strip 122 and the housing 11 with the second waterproof member 162, the risk of external water vapor, dust, etc. entering the inside of the lifting structure can be reduced, so as to improve the reliability of the lifting mechanism 1 and the camera device 30.

[0253] Please refer to Figure 20 , Figure 20 is Figure 2B another schematic diagram of the camera device 30 shown.

[0254] In some examples, the camera device 30 and the lifting assembly of the embodiments of the present application can achieve a miniaturized design. For example, when the lifting mechanism 1 meets the requirements of lifting and accommodating the camera module 2, the lifting mechanism 1 can have a height h1 and a width W. The height h1 can be in the range of 8 mm to 12.5 mm, such as 10.2 mm, 10.7 mm, 11.2 mm, etc., and the width W can be in the range of 30 mm to 42 mm, such as 32 mm, 36 mm, 40 mm, etc. Among them, the main part of the lifting mechanism 1 can have a shoulder height h2, and the shoulder height h2 can be in the range of 7 mm to 9.2 mm, such as 7.8 mm, 8.1 mm, 8.3 mm, etc. Among them, the diameter D1 of the installation space 11a of the lifting mechanism 1 can be in the range of 20 mm to 26 mm, such as 21 mm, 23 mm, 24 mm, etc. The diameter D2 of the light-transmitting area of the decorative member 13 (corresponding to Figure 18 the inner through hole 1311 of the fixing ring 131 in

[0255] In some embodiments, the height of the lifting mechanism 1 is less than the width of the lifting mechanism 1. In this embodiment, the height of the lifting mechanism 1 is small and the width is large. When the lifting mechanism 1 is applied to the electronic device 100, the height of the lifting mechanism 1 is placed corresponding to the thickness direction of the electronic device 100, and the width of the lifting mechanism 1 can be placed corresponding to the width direction or the length direction of the electronic device 100. Therefore, the lifting mechanism 1 and the camera device 30 can be better applied to the thin electronic device 100.

[0256] Please refer to Figure 21 , Figure 21 which Figure 3A is another schematic diagram of the camera device 30 shown in

[0257] In some examples, the decorative member 13 of the lifting mechanism 1 is in the dotted line position in the retracted state and in the solid line position in the extended state. The lifting stroke S of the decorative member 13 can be in the range of 9 mm to 12.5 mm, such as 9.8 mm, 10.65 mm, 11 mm, etc.

[0258] In some embodiments, the ratio of the lifting stroke of the decorative member 13 to the height of the lifting mechanism 1 may be greater than or equal to 0.8, or greater than or equal to 1. In this embodiment, by setting the number of turns of the horizontal belt 121 and the vertical belt 122 of the lifting member 12, the lifting member 12 has a high compression ratio and can flexibly adjust the lifting stroke of the lifting member 12, so that the lifting stroke is close to or exceeds the height of the lifting mechanism 1, enabling the lifting mechanism 1 to better achieve a large lifting stroke.
