Description

Lifting mechanism, camera device and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 29, 2023, with application number 202311867977.9, and priority to the Chinese patent application with the invention name "Lifting mechanism, camera device and electronic equipment", all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of terminal technology, and in particular to a lifting mechanism, a camera device and an electronic device. Background Art

[0003] 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 size of the camera module is also becoming larger and larger. Under the condition that electronic devices pursue lightness and thinness, the appearance of the camera area is seriously protruding, which greatly affects the user experience.

[0004] In related technologies, the camera can be set as a lifting structure. When shooting, part of the camera structure extends from 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 inside of the electronic device to avoid the camera protruding from the electronic device and affecting the appearance of the electronic device.

[0005] Current camera lift mechanisms primarily utilize a motor and a lead screw mechanism to drive the camera's lift. Because the lead screw's lift range is limited by the length of the lead screw, which in turn is limited by the camera's size, the lead screw's lift range is relatively short, limiting the camera's telephoto shooting capabilities. Summary of the Invention

[0006] The purpose of the embodiments of the present application is to provide a lifting mechanism, a camera device and an electronic device, wherein the lifting mechanism has a large lifting stroke, which helps to realize the telephoto shooting function of the camera device.

[0007] In a first aspect, the present application provides a lifting mechanism for use in a camera device including a camera module, wherein the lifting mechanism includes a housing, a rotating member, a driving assembly, a horizontal belt, a vertical belt, and a decorative member.

[0008] The central portion of the housing defines an installation space for mounting the camera module. A rotating member is located within the housing and surrounds the installation space, rotatably connected to the housing. A drive assembly is located within the housing and connected to the rotating member, driving the rotating member to rotate.

[0009] The horizontal band is helical and elastic, with the central axis of the helix corresponding to the central axis of rotation of the rotating member. A portion of the horizontal band is wrapped around the rotating member, while the other portion is located on the bottom side of the rotating member and housed within the housing. The elasticity of the horizontal band primarily refers to its structure being flexible and capable of deformation.

[0010] The longitudinal belt is coiled and elastic, with its winding axis corresponding to the rotation axis of the rotating member. A portion of the longitudinal belt is wound around the rotating member and meshes with the transverse belt, while the remaining portion is located outside the rotating member and housed within the housing. The elasticity of the longitudinal belt primarily refers to its structural flexibility, allowing it to deform.

[0011] 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. 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.

[0012] When the rotating member rotates forward, the horizontal belt engages with the vertical belt and rises, raising the decorative member. When the rotating member rotates backward, the horizontal belt descends and separates from the vertical belt, lowering the decorative member. The terms "forward rotation" and "reverse rotation" do not strictly define the corresponding specific rotation directions; they are opposite rotation directions. Forward rotation corresponds to the rotation direction of the rotating member capable of driving the lifting member to rise, while reverse rotation corresponds to the rotation direction of the rotating member capable of driving the lifting member to descend.

[0013] 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 realize the raising or lowering of the decorative part, thereby meeting the purpose of having sufficient optically available space for the camera module when the decorative part is raised, and also meeting the purpose of having a small overall height of the camera device when the decorative part is lowered.

[0014] Among them, the lifting part is lifted and lowered through elastic compression and release, so that the lifting stroke of the lifting part 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.

[0015] For example, the horizontal and vertical belts 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 horizontal and vertical belts of the lifting member has a high degree of freedom in design, and the number of turns of the horizontal and vertical belts 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, so as to achieve the purpose of large-scale adjustment of the lifting stroke, increase the optically available space of the camera module, reduce the protrusion of the appearance of the camera device of the electronic device, and solve the problems of the existing lifting mechanism having too small a stroke and insufficient telephoto shooting capability.

[0016] 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.

[0017] In some possible implementations, the rotating member includes a rotating drum, a plurality of engagement groups, and a guide rail. The rotating drum is rotatably connected to the housing.

[0018] Multiple meshing groups are arranged at intervals on the outer circumference of the rotating drum and are fixedly connected to the rotating drum. Each meshing group includes a top screw column and a meshing column. The top screw column is protruding from the outer side surface of the rotating drum. The meshing column is arranged opposite to the top screw column and forms a meshing gap between the top screw column and the horizontal belt and the vertical belt pass through the meshing gap and mesh in the meshing gap.

[0019] The guide rail is fixed on the outer side of the rotating drum and is spiral. The guide rail is divided into multiple sections by multiple engaging groups of top screw columns. A part of the cross belt is installed on the guide rail along the extension direction of the guide rail, and the cross belt is slidably connected to the guide rail.

[0020] The top screw post can be in the shape of an elongated strip, and the length of the top screw post can extend parallel to the axial direction of the rotating drum, that is, parallel to the central axis of the rotating drum. The top screw post and the rotating drum can be integrally formed structural parts to make the connection between the two more secure. Alternatively, the top screw post can also be fixed to the rotating drum by assembly methods such as welding, bonding, and clamping. The top screw post can be made of a material with a certain hardness, such as metal or plastic.

[0021] The engaging post can be elongated, with its length extending parallel to the length of the jackscrew post. In this case, the interlocking gap between the engaging post and the jackscrew post can also be arranged parallel to the axial direction of the rotating drum. The engaging post can be made of a material with a certain hardness, such as metal or plastic.

[0022] In the implementation of the present application, the lifting mechanism forms a set of small-volume spiral guide structures and meshing structures through the structural design of the rotating part and the lifting part and the matching structure design of the two. The spiral guide structure can realize the lifting of the elastic part in a small space. The meshing structure can make the horizontal belt and the vertical belt of the lifting part fit together tightly, thereby improving the movement stability of the lifting mechanism.

[0023] In some possible implementations, the top screw column presses against the horizontal belt, and a gap is formed between the horizontal belt and the outer side surface of the rotating drum.

[0024] In this implementation, the cross belt is supported by the top screw column, so that a gap can be created between the cross belt and the outer side surface of the rotating drum. The cross belt contacts the surfaces of the top screw columns of multiple meshing groups but does not contact the outer side surface of the rotating drum, thereby reducing the contact area between the cross belt and the rotating part, so as to reduce the friction between the two when the cross belt moves relative to the rotating part, thereby reducing the friction loss of the rotating part and the cross belt, and also helping to reduce the power consumption of the lifting mechanism.

[0025] In some possible implementations, the guide rail includes two ridges, both of which are spirally shaped and arranged opposite each other, with a guide groove formed between the two ridges, and the cross-belt portion is located in the guide groove. In this case, the guide rail is composed of two ridges, which has a simple structure, a small size, and is easy to process.

[0026] Among them, at the bottom end and the top end of the guide rail, the two protrusions are provided with chamfers on one side close to the guide groove to expand the inlet and outlet of the guide groove, making it easier for other structural parts to enter and leave the guide groove.

[0027] In some possible implementations, the guide rail and the rotating drum are integrally formed structural members. In this case, the connection between the guide rail and the rotating drum is more stable and helps to reduce the structural volume.

[0028] The guide rail may be made of a material with a certain hardness, such as metal or plastic, to better achieve a guiding effect.

[0029] In some possible implementations, the surface of the guide rail contacting the horizontal belt and / or the surface of the horizontal belt contacting the guide rail is provided with a wear-resistant layer. 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 main body of the horizontal belt. The surface of the guide rail contacting the horizontal belt can be located on the wall of the guide groove of the guide rail, and the surface of the horizontal belt contacting the guide rail can be located on the outer surface of the connecting portion of the horizontal belt.

[0030] In this implementation, by providing a wear-resistant layer at the friction position of at least one of the guide rail and the transverse belt, the friction loss between the guide rail and the transverse belt can be reduced, which is beneficial to improving the reliability of the lifting mechanism.

[0031] In some possible implementations, one or more of the surface of the top screw post facing the engagement post, the surface of the engagement post facing the top screw post, the surface of the longitudinal belt contacting the top screw post, the surface of the longitudinal belt contacting the transverse belt, and the surface of the transverse belt contacting the longitudinal belt are provided with a wear-resistant layer.

[0032] In this implementation, by providing a wear-resistant layer at at least one of the friction positions between the top screw column and the longitudinal belt, the friction position between the meshing column and the longitudinal belt, and the friction position between the transverse belt and the longitudinal belt, the friction loss between the rotating part and the lifting part can be reduced, thereby improving the reliability of the lifting mechanism.

[0033] In some possible implementations, the wear-resistant layer is a diamond-like carbon layer, a metal nitriding layer, or a metal sulfiding layer.

[0034] In some possible implementations, the axial dimension of the cross-section of the transverse strip is smaller than its radial dimension. In this case, the transverse strip is more susceptible to deformation in the axial direction. The axial dimension of the cross-section of the longitudinal strip is larger than its radial dimension. In this case, the longitudinal strip is more susceptible to deformation in the radial direction.

[0035] 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 mounted on the guide rail.

[0036] 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 spaced apart along the extension direction of the longitudinal belt.

[0037] In the meshing section of the transverse belt and the longitudinal belt, the first and second sections of the longitudinal belt are adjacent in the axial direction of the longitudinal belt, the bottom of the first section overlaps with 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.

[0038] In this implementation, in the meshing section of 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 meshing section of the transverse belt and the longitudinal belt can maintain a stable structure in the axial direction of the lifting member to have a stable height.

[0039] In some possible implementations, the engagement post abuts the longitudinal strap. The engagement post, in conjunction with the screw post, allows the longitudinal strap to engage and maintain a stable connection with the transverse strap, preventing radial movement between the two straps and improving the reliability of the lifting member and the lifting mechanism. When the rotor rotates clockwise, the engagement post drives the longitudinal strap to move radially toward the rotating member, retracting it and causing it to buckle onto the transverse strap, tightly meshing with the latter.

[0040] In some possible implementations, the engagement post is provided with a recessed escape groove for avoiding the cross belt. The escape groove of the engagement post can be recessed from the surface of the engagement post facing the screw post toward the interior of the engagement post. The escape grooves of the engagement posts of multiple engagement groups can be located at different heights along the axial direction of the drum.

[0041] In this implementation, the engaging column can not only maintain a supporting relationship with the longitudinal belt, but also allow the teeth of the transverse belt to have a larger height through the 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 engaging relationship with the longitudinal belt.

[0042] 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 engaging posts of the plurality of engaging groups are fixed to the connecting ring, and the plurality of connecting posts are connected one-to-one between the bottoms of the engaging posts and the jackscrew posts.

[0043] 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 snapped into the groove to form a match.

[0044] In this implementation, the engaging column is fixedly connected to the rotating drum through the connecting column and the top screw column. The relative position relationship between the connecting column and the top screw column is stable, so that the relative position relationship between the engaging column and the top screw column is stable and not easy to shift.

[0045] In some possible implementations, the rotating member further includes a turntable, which surrounds the outer circumference of the rotating drum and is located on the bottom side of the guide rail. The turntable is fixedly connected to the rotating drum, and the driving assembly is connected to the turntable.

[0046] In this implementation, the driving assembly drives the rotating member to rotate by driving the turntable to rotate.

[0047] In some possible implementations, the drive assembly may include a driver and a transmission assembly, and the driver can transmit power and motion through the transmission assembly.

[0048] In this implementation, the drive assembly can change the direction and speed of the output power through the specific structural design of the transmission assembly to better drive the driven structure of the lifting mechanism. For example, the transmission assembly can act as a speed reduction mechanism to reduce the high speed of the motor to an appropriate speed before outputting it.

[0049] In some possible implementations, a first storage cavity is formed between the turntable and the housing, the first storage cavity being located at the bottom side of the turntable, the turntable having an inlet and outlet hole communicating with the first storage cavity, and the transverse belt passing through the inlet and outlet hole and partially located in the first storage cavity.

[0050] In this implementation, by setting up the first storage cavity, the horizontal 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 designing the number of turns of the horizontal belt is also relatively high.

[0051] Among them, the last circle of the transverse belt located in the first storage cavity (that is, the circle at the bottom) can be fixedly connected to the shell so that during the lifting process, the transverse belt mainly moves along the axial direction of the rotating part, and there is less displacement in the circumferential direction of the rotating part, so that when the rotating part rotates, it can better drive the transverse belt to perform axial lifting and lowering, thereby ensuring the accuracy and reliability of the driving action.

[0052] In some possible implementations, a second storage cavity is formed between the rotating member and the housing, and the second storage cavity surrounds the outer periphery of the rotating member. The longitudinal belt passes through the space between the engagement columns of two adjacent engagement groups and is partially located in the second storage cavity.

[0053] In this implementation, by setting up a 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 designing the number of turns of the longitudinal belt is also relatively high.

[0054] Among them, the last circle of the longitudinal belt located in the second storage chamber (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 along the radial direction of the rotating part, and there is less displacement in the circumferential direction of the rotating part, so that 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.

[0055] In some possible implementations, the multiple 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 entry and exit holes, the second meshing group is offset from the entry and exit holes, and the bottom end of the guide rail is located between the entry and exit holes and the second meshing group. That is, the first meshing group is located in the space above the entry and exit holes, the second meshing group is offset from the space above the entry and exit holes, and the bottom end of the guide rail is located near the entry and exit holes.

[0056] In this implementation, the relative positions of the first and second meshing groups, the access holes, and the bottom end of the guide rail are arranged so that, after the horizontal belt ascends from the first storage chamber, it passes through the access holes of the turntable, enters the guide rail from the bottom end, and then engages with the vertical belt at the second meshing group. Furthermore, as the vertical belt descends, after leaving the second meshing group, the horizontal belt disengages the guide rail, enters the first storage chamber through the access holes of the turntable, and completely separates from the vertical belt at the first meshing group.

[0057] 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.

[0058] In this embodiment, when the drive assembly drives the rotating member to rotate forward, the guide rail drives the transverse belt to rise, and a portion of the longitudinal belt engages with the transverse belt and rises with the transverse belt, allowing the lifting mechanism to transition from a retracted state to an extended state. Part of the transverse belt can be lifted upward from the first storage cavity, passed through the access hole of the turntable, and entered the guide rail at the bottom end of the guide rail of the rotating member. Part of the longitudinal belt can be retracted inward from the second storage cavity, passed between the engagement posts of the first engagement group and the engagement posts of the second engagement group, entered the rotating member, and engaged with the transverse belt in the engagement gap of the second engagement group of the rotating member. The engaged portion of the transverse belt and the longitudinal belt rises to the top side of the guide rail.

[0059] When the drive assembly drives the rotating member to rotate in the opposite direction, the guide rail drives the transverse belt to descend, and a portion of the longitudinal belt can descend with the transverse belt and disengage from the transverse belt, and the lifting mechanism can be transformed from the extended state to the retracted state. The meshing sections of the transverse belt and the longitudinal belt can descend, and between the first meshing group and the second meshing group, a portion of the transverse belt disengages from the guide rail, passes through the entry and exit holes of the turntable, and enters the first storage cavity. A portion of the longitudinal belt disengages from the transverse belt, then expands outward, passes between the meshing posts of the first meshing group and the meshing posts of the second meshing group, and enters the second storage cavity. The transverse belt and the longitudinal belt are completely separated at the position corresponding to the second meshing group.

[0060] In some possible implementations, the housing includes a base and an upper shell.

[0061] The base includes a bottom wall, an inner wall, a first outer 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 wall is connected to the inner periphery of the bottom wall. The bottom end of the first outer wall is connected to the outer periphery of the bottom wall. The first connecting wall surrounds the outer periphery of the first outer wall and is connected to the top of the first outer wall. The first storage cavity surrounds the outer periphery of the inner wall. The base also has a sink, which is located between the inner wall and the first outer wall and on the top side of the first storage cavity. The sink is connected to the first storage cavity.

[0062] The upper shell includes a top wall, a second outer 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 wall is connected to the outer edge of the top wall. The second connecting wall surrounds the outer peripheral side of the second outer wall and is connected to the bottom end of the second outer wall. The partition wall is located on the inner side of the second outer wall and is connected to the bottom end of the second outer wall. The second storage cavity is located between the top wall and the partition wall.

[0063] The second connecting wall is fixedly connected to the first connecting wall, the isolation wall is located on the top side of the sink, and the turntable is installed in the sink.

[0064] In some possible implementations, 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.

[0065] In this implementation, by providing a counterweight hole and / or counterweight block on the turntable, the center of gravity of the rotating member is located on the central axis of rotation of the rotating member. This can reduce the risk of the rotating member rotating when the lifting mechanism falls, which helps to ensure the reliability of the mechanism. In addition, the center of gravity of the rotating member is located on the central axis of rotation of the rotating member, which also means that the rotating member will not be overweight during rotation, or the overweight will be very slight, thereby avoiding the problem of large localized wear of the rotating member (during the friction process, the wear of the structural member is generally significantly greater than the wear of the lighter parts), thereby extending the service life of the rotating member and improving the reliability of the rotating member and the lifting mechanism.

[0066] In some possible implementations, the decorative element includes a fixed ring and a light-transmitting sheet. The light-transmitting sheet is fixed to the inner periphery of the fixed ring and covers the inner through-hole of the fixed ring. The outer periphery of the fixed ring is connected to the longitudinal strap. For example, the light-transmitting sheet can be a light-transmitting lens. The longitudinal strap can be inserted into the fixing groove of the fixed ring to increase the stability and firmness of the connection between the longitudinal strap and the decorative element.

[0067] In this implementation, the decorative member is located on the top side of the shell, and the light-transmitting sheet of the decorative member is arranged corresponding to the installation space of the shell, so that light on the top side of the lifting mechanism can pass through the light-transmitting sheet and enter the installation space.

[0068] In some possible implementations, the lifting mechanism also includes a first waterproof part, the top end of the first waterproof part is sealed and connected to the periphery of the decorative part, and the other end of the first waterproof part is used to seal and connect to the camera module. The first waterproof part is annular and can be extended and retracted along the axial direction of the rotating part.

[0069] When the lifting mechanism is in the retracted state, the first waterproof member is in a compressed state and has a cylindrical structure with obvious wrinkles. When the lifting mechanism is in the extended state, the first waterproof member is in an expanded state and can have a smooth cylindrical structure or a cylindrical structure with slight wrinkles. The height of the first waterproof member in the expanded state is greater than the height of the first waterproof member in the compressed state.

[0070] In this implementation, the periphery of the decorative component and the camera module are sealed and connected by the first waterproof component, which can reduce the risk of external water vapor, dust, etc. entering the light incident surface of the camera module, thereby improving the waterproof and dustproof performance of the camera device, which is conducive to ensuring the shooting quality of the camera device.

[0071] In some possible implementations, the longitudinal belt passes through the top wall of the shell, and the top wall of the shell has an inner side surface facing the longitudinal belt; the lifting mechanism also includes a second waterproof component, which is annular and fixed to the inner side surface of the top wall of the shell and abuts the longitudinal belt.

[0072] In this implementation, the gap between the longitudinal strip and the shell is sealed by the second waterproof member, which can reduce the risk of external water vapor, dust, etc. entering the interior of the lifting structure, thereby improving the reliability of the lifting mechanism and the camera device.

[0073] In some possible implementations, the height of the lifting mechanism is smaller than the width of the lifting mechanism, wherein the height of the lifting mechanism refers to the height of the lifting mechanism when it is in the retracted state, and the width of the lifting mechanism refers to the height of the lifting mechanism when it is in the retracted state.

[0074] In this implementation, the height of the lifting mechanism is smaller and the width is larger. When the lifting mechanism is used in 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 length direction of the electronic device. Therefore, the lifting mechanism and the camera device can be better suitable for thin electronic devices.

[0075] In some possible implementations, the ratio of the lifting stroke of the decorative component to the height of the lifting mechanism is greater than or equal to 0.8, or greater than or equal to 1. The height of the lifting mechanism refers to its height when it is in a retracted state.

[0076] In this implementation, by setting the number of turns of the horizontal and vertical belts of the lifting member, the lifting member has a high compression ratio, and the lifting stroke of the lifting member can be flexibly adjusted so that the lifting stroke is close to or exceeds the height of the lifting mechanism, so that the lifting mechanism can better achieve a large lifting stroke.

[0077] In a second aspect, the implementation method of the present application further provides a camera device, comprising a camera module and any of the above-mentioned lifting mechanisms, wherein the camera module is fixedly connected to the lifting mechanism.

[0078] In the present application, the camera device can have a smaller height when the lifting mechanism is in the retracted state, so as to be installed in an electronic device; it can also have sufficient optically available space when the lifting mechanism is in the extended state, so as to realize the telephoto shooting function.

[0079] On the third aspect, the implementation method of the present application further provides an electronic device, including a housing and the above-mentioned camera device, the camera device is installed in the housing, and the decorative parts of the lifting mechanism of the camera device are exposed relative to the housing.

[0080] In this implementation, the decorative element of the lifting mechanism can be raised and lowered through the through-hole. When the lifting mechanism is retracted, the decorative element is close to the housing, and the overall height of the lifting mechanism and camera assembly is reduced, making the camera assembly easier to install in the electronic device and reducing its protrusion from the electronic device's exterior surface, which is beneficial to the electronic device's appearance and thickness design.

[0081] When the lifting mechanism is extended, the decorative element rises and moves away from the housing, creating optically available space for the camera module beneath it. This optically available space allows the camera module to extend and retract its lens, achieving zoom, resulting in higher-quality images and better telephoto capabilities.

[0118] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0119] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Multiple" means at least two. "And / or" is a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: the existence of A alone, the existence of A and B at the same time, and the existence of B alone.

[0120] The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "inside", "outside", "top", "bottom", "side", etc., are only references to the directions in the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0121] In the embodiments of the present application, the limitations of the relative position relationship mentioned, such as parallel, perpendicular, aligned, etc., are all for the current state of the art, rather than absolutely strict limitations, and a small amount of deviation is allowed, and it is possible to be approximately parallel, approximately perpendicular, approximately aligned, etc. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 degrees and 100 degrees.

[0122] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0123] Please refer to Figure 1A and Figure 1B in combination. Figure 1A is a structural diagram of an electronic device 100 provided in some embodiments of the present application, and Figure 1B is a partial exploded structural diagram of the electronic device 100 shown in Figure 1A.

[0124] In some embodiments, the electronic device 100 can be a device with a camera function, such as a mobile phone, a tablet personal computer, a laptop computer, a smart screen, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet. In the embodiment of FIG1A , the electronic device 100 is described as a mobile phone. Of course, other types of electronic devices can also adopt similar structures, which will not be described in detail below.

[0125] It will be understood that Figures 1A and 1B only schematically illustrate some components included in the electronic device 100, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figures 1A and 1B. The electronic device 100 may also include more or fewer components compared to Figures 1A and 1B.

[0126] In some embodiments, the electronic device 100 may include a screen 10, a housing 20, and a camera device 30. The screen 10 is used to display images, videos, and the like. The screen 10 may include a translucent panel 101 and a display screen 102. The translucent panel 101 and the display screen 102 are stacked and fixedly connected. The translucent panel 101 primarily serves to protect and dustproof the display screen 102. The material of the translucent 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 (OLED) display screen, a micro organic light-emitting diode (OLED) display screen, a micro organic light-emitting diode (OLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0127] 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 part 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 fixed to the cover plate 201 by adhesive. The frame 202 may also be an integrally molded structure with the cover plate 201, that is, the frame 202 and the cover plate 201 are a single-piece structure. The frame 202 is located between the cover plate 201 and the light-transmitting panel 101. The light-transmitting panel 101 may be fixed to the frame 202 by adhesive. The light-transmitting panel 101, the cover plate 201, and the frame 202 enclose an internal storage space of the electronic device 100. The internal storage space accommodates the display screen 102. The cover plate 201 can be made of metal, plastic, glass, or other materials. The cover plate 201 can be a single material plate or a plate structure composed of multiple materials and multiple panels. The cover plate 201 is provided with a mounting opening 2011, and the camera decorative member 203 covers and is fixed to the mounting opening 2011.

[0128] Illustratively, the camera device 30 is used to capture photos / videos. Illustratively, the camera device 30 is mounted on the housing 20, with a major portion or the entirety of the device 100 located within the internal storage space. The camera device 30 can function as a rear-facing camera module. For example, the light-entering surface of the camera device 30 faces the camera trim 203. The camera trim 203 is used to protect the camera device 30.

[0129] 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 for 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 storage space of the electronic device 100.

[0130] The camera decorative member 203 is provided with a through hole 204. Through hole 204 allows scene light to enter the light-entering surface of the camera device 30. Part of the structure of the camera device 30 may be exposed through through hole 204. In other embodiments, the electronic device 100 may not include the camera decorative member 203. In this case, the cover plate 201 is no longer provided with a mounting opening, but instead provided with through hole 204. Part of the structure of the camera device 30 may be exposed through through hole 204, allowing scene light to enter the light-entering surface of the camera device 30.

[0131] In other embodiments, the camera device 30 can also be used as a front-facing camera module. For example, the light-entering surface of the camera device 30 faces the light-transmitting panel 101. The display screen 102 is provided with a light path avoidance hole. This light path avoidance hole allows scene light to pass through the light-transmitting panel 101 and then enter the light-entering surface of the camera device 30. In other embodiments, the electronic device 100 may also include one or more other camera modules (not shown in the figure), which is not strictly limited in the present embodiment.

[0132] In some embodiments, as shown in FIG1B , the electronic device 100 further includes a circuit board 50 and an image processor 60, the circuit board 50 and the image processor 60 being located in the internal accommodation space of the electronic device 100, and the image processor 60 being 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. The communication connection between the camera device 30 and the image processor 60 may include data transmission through electrical connection methods such as wiring, or data transmission may be achieved through coupling or other methods. It is understandable that the camera device 30 and the image processor 60 may also be communicatively connected through other methods that can achieve data transmission.

[0133] 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). 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. The image processor 60 then processes the digital image signal and ultimately displays the image or video on the screen 10.

[0134] In some embodiments, the electronic device 100 may further include a memory (not shown), which is communicatively connected to the image processor 60. The image processor 60 processes the digital image signal and then transfers the image to the memory, so that the image can be retrieved from the memory and displayed on the screen 10 at any time when the image is needed. In some embodiments, the image processor 60 may also compress the processed digital image signal before storing it in the memory to save memory space.

[0135] In some embodiments, the electronic device 100 may further include a driver chip (not shown in the figure), which is communicatively connected to the camera device 30 and can be used to drive at least part of the structure of the camera device 30 to move.

[0136] In some other embodiments, the electronic device 100 may not include the screen 10 .

[0137] It will be understood that the installation location of the camera device 30 of the electronic device 100 in the embodiment shown in Figures 1A and 1B is merely illustrative, and this application does not strictly limit the installation location of the camera device 30. In some other embodiments, the camera device 30 may also be installed in other locations 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 be rotated, moved, or detached relative to the terminal body, and the camera device 30 may also be provided on the auxiliary component.

[0138] Please refer to Figures 2A to 3B in combination. Figure 2A is a structural schematic diagram of the camera device 30 shown in Figure 1B in some embodiments, Figure 2B is a cross-sectional structural schematic diagram of the camera device 30 shown in Figure 2A taken along AA, Figure 3A is a structural schematic diagram of the camera device 30 shown in Figure 2A in another usage state, and Figure 3B is a cross-sectional structural schematic diagram of the camera device 30 shown in Figure 3A taken along BB.

[0139] For the convenience of description in the following text, the camera device 30 is defined as having a width direction X, a length direction Y and a height direction Z, and the above three directions are perpendicular to each other. 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 201 and the screen 10 of the electronic device 100. Among them, the light incident side of the camera device 30 (that is, the side for light intake) 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 used as a rear camera, the side of the camera device 30 close to the cover 201 is its top side, and the side close to the screen 10 is its bottom side. In the relevant description below, the camera device 30 and its components and structures close to the light incident side are "top", and the side away 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.

[0140] 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 shell 11, a lifting member 12 and a decorative member 13. The shell 11 has an installation space 11a in the middle, and the installation space 11a extends from the top side of the shell 11 to the bottom side of the shell 11. The lifting member 12 can be installed on the shell 11, and the lifting member 12 is a movable member. At least part of the lifting member 12 can rise or fall relative to the shell 11 to extend or retract the shell 11. The decorative member 13 is located on the top side of the shell 11 and covers the installation space 11a. 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. The middle part of the decorative member 13 is a light-transmitting structure, so external light can pass through the decorative member 13 and enter the installation space 11a.

[0141] 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 be fixedly connected to the lifting mechanism 1. The camera module 2 can be at least partially located in the installation space 11a. For example, a portion of the camera module 2 can be located in the installation space 11a and located on the inner side of the lifting mechanism 1, and another portion of the camera module 2 can be located on the bottom side of the lifting mechanism 1; or, the entire camera module 2 is located in the installation space 11a. The lens of the camera module 2 is located in the installation space 11a and is arranged toward the middle of the decorative part 13. The camera module 2 captures light passing through the decorative part 13 to take pictures.

[0142] In this embodiment, the lifting mechanism 1 has a retracted state and an extended state. As shown in Figures 2A and 2B, when the lifting mechanism 1 is in the retracted state, the lifting member 12 is stored inside the housing 11, and the decorative member 13 is close to the top of the housing 11 (for example, it may 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, making it easy to install the camera device 30 in the electronic device 100 and reducing its protrusion height on the exterior surface of the electronic device 100, which is beneficial to the appearance design and thickness design of the electronic device 100.

[0143] As shown in Figures 3A and 3B , when lifting mechanism 1 is in the extended position, lifting member 12 partially extends outside housing 11, and decorative member 13 rises away from the top of housing 11. A movable space 11b is formed below decorative member 13, connecting to mounting space 11a. This movable space 11b forms an optically usable space for camera module 2. In this state, camera module 2 can extend and retract its lens through movable space 11b, achieving zoom, resulting in higher-quality images and better telephoto shooting capabilities.

[0144] For example, referring 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 is positioned toward the outer shell 20 (e.g., the camera decorative member 203 or the cover 201), and the decorative member 13 of the lifting mechanism 1 can be exposed relative to the outer shell 20, for example, by being exposed in the through hole 204. In this case, the decorative member 13 can be raised and lowered 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 reuse the thickness space of the electronic device 100, which is conducive to the thinning of the electronic device 100.

[0145] In some embodiments, the lifting member 12 can be an elastic member, and the lifting member 12 is lifted and lowered by elastic compression and release, so that the lifting stroke of the lifting member 12 is less restricted by the rigid transmission mechanism, so that it has a larger lifting stroke, so that the camera module 2 has a higher optically available space in the extended state of the lifting mechanism 1, which is conducive to achieving telephoto shooting.

[0146] Please refer to FIG. 2A and FIG. 4 . FIG. 4 is a schematic diagram of the exploded structure of the camera device 30 shown in FIG. 2A .

[0147] In some embodiments, the lifting mechanism 1 is modular, and the camera module 2 is also modular, and the two are assembled to form the camera device 30. In this embodiment, the lifting mechanism 1 provides an installation space 11a and a movable space 11b for the camera module 2. The camera module 2 is connected to the housing 11 (a stationary component) 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 the camera module 2. Therefore, the camera module 2 is not affected by the lifting accuracy of the lifting mechanism 1, thereby ensuring excellent image quality.

[0148] The following describes the implementation structure of the lifting mechanism 1 by way of example.

[0149] Please refer to FIG. 5 , which is a schematic diagram of the exploded structure of the lifting mechanism 1 shown in FIG. 4 .

[0150] In some embodiments, the lifting mechanism 1 includes the aforementioned 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. Specifically, 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; and the fastening assembly 17 may include a plurality of fasteners 171.

[0151] Please refer to Figures 6 to 8B in combination. Figure 6 is a structural schematic diagram of the base 111 of the lifting mechanism 1 shown in Figure 5, Figure 7 is a structural schematic diagram of the upper shell 112 of the lifting mechanism 1 shown in Figure 5, Figure 8A is a structural schematic diagram of the base 111 shown in Figure 6 and the upper shell 112 shown in Figure 7 assembled into the shell 11, and Figure 8B is a cross-sectional structural schematic diagram of the shell 11 shown in Figure 8A taken along CC.

[0152] In some embodiments, the base 111 can be hollow, with a space formed inside the base 111. The inner space 111a of the base 111 extends from the top of the base 111 to the bottom of the base 111. The upper shell 112 can be hollow, with a space formed inside the upper shell 112. The inner space 112a of the upper shell 112 extends from the top of the upper shell 112 to the bottom of the upper shell 112. The base 111 and the upper shell 112 are fixed to each other to form the housing 11. The inner space 111a of the base 111 and the inner space 112a of the upper shell 112 together form the aforementioned installation space 11a of the housing 11.

[0153] For example, the base 111 and the upper shell 112 can be fixedly connected by a plurality of fasteners 171 of the fastening assembly 17. The base 111 and the upper shell 112 can both be provided with fastening holes to facilitate fastening by the fasteners 171. The fasteners 171 can be screws, bolts, rivets, or other structures. In other embodiments, the base 111 and the upper shell 112 can also be fixed by means of a connection method such as clamping, bonding, or welding. 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.

[0154] In some embodiments, as shown in Figures 6 and 8B, the base 111 may include a bottom wall 1111, an inner sidewall 1112, a first outer sidewall 1113, and a first connecting wall 1114. A first through hole is provided in the middle of the bottom wall 1111. The bottom end of the inner sidewall 1112 is connected to the inner periphery of the bottom wall 1111. The inner sidewall 1112 stands upright relative to the bottom wall 1111 and has a certain height. In this case, the inner sidewall 1112 surrounds the first through hole and forms a space connected to the first through hole. This space and the first through hole together form the inner space 111a of the base 111.

[0155] In some examples, the inner sidewall 1112 may be provided with one or more notches 111b, which communicate with the inner space 111a of the base 111. If there are multiple notches 111b, the notches 111b may be arranged spaced apart from each other along the circumference of the inner sidewall 1112. In this case, the notches 111b extend through the inner surface of the inner sidewall 1112, thereby reducing the inner surface area of ​​the inner sidewall 1112.

[0156] The bottom end of the first outer wall 1113 is connected to the outer periphery of the bottom wall 1111. The first outer wall 1113 stands upright relative to the bottom wall 1111 and has a certain height. The first outer wall 1113 is disposed opposite the inner wall 1112. The first connecting wall 1114 surrounds the outer periphery of the first outer wall 1113 and is connected to the top end of the first outer wall 1113. The first connecting wall 1114 may have a plurality of fastening holes.

[0157] Exemplarily, the base 111 may have a first storage cavity 111c and a sink 111d. 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, which faces the top side of the base 111. The first storage cavity 111c may be formed by the bottom wall 1111 and the inner side wall 1112, or the first storage cavity 111c may be formed by the bottom wall 1111 being recessed. The embodiment of the present application does not strictly limit the specific implementation structure of the first storage cavity 111c. The sink 111d is located between the inner side wall 1112 and the first outer side wall 1113 and is located on the top side of the first storage cavity 111c. The sink 111d is connected to the first storage cavity 111c. The bottom wall 1111 of the sink 111d may be partially located on the outer peripheral side of the first storage cavity 111c and partially located on the inner peripheral side of the first storage cavity 111c.

[0158] The base 111 may further include a first groove 111e and a second groove 111f. The first groove 111e and the second groove 111f may be formed by the bottom wall 1111 being recessed, or may be formed by the bottom wall 1111 and the first outer side wall 1113. The base 111 may further include a first protrusion 1115 and a second protrusion 1116. The first protrusion 1115 is located in the first groove 111e and is fixed to the bottom wall 1111. The first protrusion 1115 is provided with a shaft insertion hole. The second protrusion 1116 is located in the first groove 111e and is spaced apart from the first protrusion 1115. The second protrusion 1116 is fixed to the bottom wall 1111. The second protrusion 1116 is provided with a shaft insertion hole.

[0159] In some embodiments, as shown in Figures 7 and 8B, the upper shell 112 may include a top wall 1121, a second outer wall 1122, a second connecting wall 1123, and a partition wall 1124. A second through hole is defined in the middle of the top wall 1121. The top of the second outer wall 1122 is connected to the outer periphery of the top wall 1121. The second outer wall 1122 stands upright relative to the top wall 1121 and has a certain height. The second connecting wall 1123 surrounds the outer periphery of the second outer wall 1122 and connects to the bottom end of the second outer wall 1122. The second outer wall 1122 may have multiple fastening holes. The partition wall 1124 is located inside the second outer wall 1122 and connects to the bottom end of the second outer wall 1122. A third through hole may be defined in the middle of the partition wall 1124. The third through hole is opposite to and connected to the second through hole. The third through hole, the second through hole, and the space therebetween together form the inner space 112a of the upper shell 112.

[0160] For example, the upper shell 112 may have a second storage cavity 112b located inside the second outer wall 1122 and between the top wall 1121 and the partition wall 1124. The second storage cavity 112b may be disposed around the inner space 112a of the upper shell 112 and communicate with the inner space 112a of the upper shell 112.

[0161] The upper shell 112 may further include a third groove 112c, which may be formed by a depression in the second connecting wall 1123. The upper shell 112 may further include a third protrusion 1125 and a fourth protrusion 1126. The third protrusion 1125 and the fourth protrusion 1126 are both fixed to the second connecting wall 1123 and protrude relative to the bottom surface of the second connecting wall 1123. The third protrusion 1125 and the fourth protrusion 1126 are spaced apart and each has a shaft hole.

[0162] In some embodiments, as shown in Figures 6 to 8B, when the upper shell 112 is fixed to the base 111, the second connecting wall 1123 is fixedly connected to the first connecting wall 1114. Specifically, a plurality of fasteners 171 can be fixedly connected to the first connecting wall 1114 and the second connecting wall 1123 through the fastening holes of the first connecting wall 1114 and the fastening holes of the second connecting wall 1123. Specifically, the isolation wall 1124 is located on the top side of the sink 111d. At this time, the second storage cavity 112b is located on the top side of the sink 111d. Specifically, the first inner side wall 1112 can extend into the inner space 112a of the upper shell 112 through the third through-hole portion of the isolation wall 1124, and the inner space 111a of the base 111 and the inner space 112a of the upper shell 112 are connected, and there is a certain overlapping area between the two. In addition, the first inner wall 1112 and the isolation wall 1124 are spaced apart from each other, and a gap between the first inner wall 1112 and the isolation wall 1124 is located at the top side of the first storage cavity 111 c .

[0163] The second connecting wall 1123 covers the first groove 111e. The first protrusion 1115 and the third protrusion 1125 are arranged opposite each other, and the rotation axis hole of the first protrusion 1115 is coaxial with the rotation axis hole of the third protrusion 1125. The second protrusion 1116 and the fourth protrusion 1126 are arranged opposite each other, and the rotation axis hole of the second protrusion 1116 is coaxial with the rotation axis hole of the fourth protrusion 1126. The second groove 111f and the third groove 112c are aligned, forming a larger space.

[0164] Please refer to FIG. 9 , which is a schematic structural diagram of the driving assembly 15 shown in FIG. 5 in some embodiments.

[0165] In some embodiments, the drive assembly 15 may include a drive member 151 and a transmission assembly 152. The drive member 151 can transmit power and motion through the transmission assembly 152. For example, the drive member 151 may be a motor. The transmission assembly 152 may include a worm 1521, a first turret tooth 1522, and a second turret tooth 1523. The worm 1521 may be fixedly connected to the output shaft of the motor. The first turret tooth 1522 includes a first tooth portion 15221 and a second tooth portion 15222 that are coaxial and fixed to each other. The first tooth portion 15221 of the first turret tooth 1522 engages with the worm 1521. The second turret tooth 1523 includes a first tooth portion 15231 and a second tooth portion 15232 that are coaxial and fixed to each other. The first tooth portion 15231 of the second turret tooth 1523 engages with the second tooth portion 15222 of the first turret tooth 1522. The second tooth portion 15232 of the second turret tooth 1523 serves as the final output member of the drive assembly 15.

[0166] In this embodiment, the drive assembly 15 can change the direction and speed of the output power through the specific structural design of the transmission assembly 152 to better drive the driven structure of the lifting mechanism 1. For example, the transmission assembly 152 can function as a speed reduction mechanism to reduce the high speed of the motor to a suitable speed before output. It is understood that the drive assembly 15 can also have other implementation structures, and this embodiment of the application is not strictly limited to this.

[0167] Among them, the distance between the second tooth portion 15232 of the second tower tooth 1523 and the first tooth portion 15231 is greater than the distance between the first tooth portion 15221 and the second tooth portion 15222 of the first tower tooth 1522, so that the second tooth portion 15232 of the second tower tooth 1523 is higher than the first tooth portion 15221 of the first tower tooth 1522. The power and motion output of the second tooth portion 15232 of the second tower tooth 1523 will not be interfered with by the first tooth portion 15221 of the first tower tooth 1522, which is conducive to ensuring the reliability and stability of the output action.

[0168] Please refer to FIG. 6 , FIG. 7 and FIG. 10 . FIG. 10 is a schematic diagram of the assembly structure of the driving assembly 15 shown in FIG. 9 and the base 111 shown in FIG. 6 .

[0169] In some embodiments, the drive assembly 15 is located in the housing 11. The drive assembly 15 can be installed on the base 111 and cooperate with the upper shell 112. For example, the drive member 151 of the drive assembly 15 can be installed in the second groove 111f, and the drive member 151 is partially located in the second groove 111f and partially located in the third groove 112c. The transmission assembly 152 is installed in the first groove 111e. The two ends of the rotating shaft of the first tower tooth 1522 can be respectively inserted into the rotating shaft hole of the second protrusion 1116 and the rotating shaft hole of the fourth protrusion 1126 to achieve positioning. The two ends of the rotating shaft of the second tower tooth 1523 can be respectively inserted into the rotating shaft hole of the first protrusion 1115 and the rotating shaft hole of the third protrusion 1125 to achieve positioning.

[0170] Please refer to Figures 11A to 11D. Figure 11A is a structural schematic diagram of the rotating member 14 shown in Figure 5 in some embodiments, Figure 11B is a decomposed structural diagram of the rotating member 14 shown in Figure 11A, Figure 11C is a structural schematic diagram of the rotating member 14 shown in Figure 11A at another angle, and Figure 11D is a decomposed structural diagram of the rotating member 14 shown in Figure 11C.

[0171] In some embodiments, the rotating member 14 includes a rotating drum 141 , a plurality of engagement groups 142 , a connecting ring 143 , a plurality of connecting posts 144 , a guide rail 145 , and a rotating disk 146 .

[0172] For example, the drum 141 is a cylindrical structure, and a through space is formed inside the drum 141. The drum 141 can be made of a material with a certain hardness, such as metal or plastic. The drum 141 can have a central axis 141o.

[0173] Exemplarily, multiple meshing groups 142 are arranged at intervals on the outer circumference of the rotating drum 141 and are all fixedly connected to the rotating drum 141. That is, multiple meshing groups 142 are arranged on the outer side of the rotating drum 141 along the circumference of the rotating drum 141. The number of meshing groups 142 can be two or more, such as two, three, four, five, etc., and the present embodiment uses four as an example. For example, the multiple 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 circumference of the rotating drum 141.

[0174] Wherein, each engaging group 142 includes a top screw column 1421 and an engaging column 1422. The top screw column 1421 is protruded from the outer side surface of the rotating drum 141. At this time, the top screw column 1421 protrudes a certain height relative to the outer side surface of the rotating drum 141. Wherein, the surface of the top screw column 1421 facing away from the rotating drum 141 can be an arc surface, or a plane, or a spliced ​​curved surface of a plane and an arc surface. Wherein, the top screw column 1421 can be in the shape of an elongated strip, and the length extension direction of the top screw column 1421 can be parallel to the axial direction of the rotating drum 141, that is, parallel to the central axis 141o of the rotating drum 141.

[0175] The jackscrew post 1421 and the rotating drum 141 can be integrally formed to provide a more secure connection. In other embodiments, the jackscrew post 1421 can also be secured to the rotating drum 141 by assembly, such as welding, bonding, or clamping. The jackscrew post 1421 can be made of a material with a certain hardness, such as metal or plastic.

[0176] The engaging column 1422 is arranged opposite to the top screw column 1421, and an engaging gap 1423 is formed between the engaging column 1422 and the top screw column 1421. The engaging column 1422 can be in the shape of an elongated strip, and the length extension direction of the engaging column 1422 is parallel to the length extension direction of the top screw column 1421. At this time, the engaging gap 1423 between the engaging column 1422 and the top screw column 1421 can also be arranged in a direction parallel to the axial direction of the rotating drum 141. The surface of the engaging column 1422 facing the top screw column 1421 can be a plane, or a curved surface, or a spliced ​​curved surface of a plane and a curved surface. The engaging column 1422 can be made of a material with a certain hardness, such as metal or plastic.

[0177] The engagement post 1422 is provided with a recessed escape groove 1424. The escape groove 1424 can be recessed from the surface of the engagement post 1422 facing the jackscrew post 1421 into the interior of the engagement post 1422. The escape grooves 1424 of the engagement posts 1422 of the multiple engagement groups 142 can be arranged at different heights along the axial direction of the rotating drum 141. For example, the escape 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 can be arranged in increasing heights, with the line connecting these escape grooves along the circumference of the rotating shaft forming a spiral shape.

[0178] In addition to the aforementioned escape groove (referred to as the first escape groove), the engagement column of the second engagement group 142b may also be provided with another escape groove (referred to as the second escape groove), with the second escape groove located on top of the first escape groove. In this case, the heights of the first escape groove of the second engagement group 142b, the escape groove of the third engagement group 142c, the escape groove of the fourth engagement group 142d, the escape groove of the first engagement group 142a, and the second escape groove of the second engagement group 142b increase in sequence, and the connecting line forms a spiral.

[0179] Illustratively, the connecting ring 143 is located on the outer periphery of the rotating drum 141, and is spaced apart from the rotating drum 141. The tops of the engagement posts 1422 of the multiple engagement groups 142 are all fixed to the connecting ring 143. The engagement posts 1422 of the multiple engagement groups 142 and the connecting ring 143 can be integrally formed structural members, or can be assembled to form a single integral structure.

[0180] Wherein, the number of connecting posts 144 is the same as the number of engaging posts 1422. A plurality of connecting posts 144 are connected between the bottom of the engaging post 1422 and the top screw post 1421 in a one-to-one correspondence. Wherein, a concave-convex matching structure can be formed between the corresponding connecting posts 144 and the top screw post 1421. For example, the end of the connecting post 144 connected to the top screw post 1421 can be provided with a groove, and the top screw post 1421 is snapped into the groove to form a match. At this time, the engaging post 1422 is fixedly connected to the rotating drum 141 through the connecting post 144 and the top screw post 1421, and the relative positional relationship between the connecting post 144 and the top screw post 1421 is stable, so that the relative positional relationship between the engaging post 1422 and the top screw post 1421 is stable and not prone to displacement. Wherein, the corresponding engaging post 1422 and the connecting post 144 can be an integrally formed structural member, or can be formed into an integral structure by assembly.

[0181] Exemplarily, the guide rail 145 is fixed to the outer side surface of the rotating drum 141 and is spiral-shaped. The guide rail 145 is divided into multiple sections by the top screw columns 1421 of the multiple meshing groups 142. That is, the guide rail 145 is disconnected at the position corresponding to the top screw column 1421 to form a multi-segment structure. The multi-segment structure as a whole is still spiral-shaped, and each section structure is a part of the spiral. Among them, the avoidance groove 1424 of the meshing column 1422 is provided corresponding to the disconnection point of the two adjacent sections. Among them, the spiral center line 145o of the guide rail 145 can coincide with the central axis 141o of the rotating drum 141 to be parallel to the axial direction of the rotating drum 141. Among them, the guide rail 145 can be a right-handed spiral structure or a left-handed spiral structure. The embodiment of the present application is illustrated as a right-handed spiral structure of the guide rail 145.

[0182] The guide rail 145 and the rotating drum 141 can be integrally formed, thereby ensuring a more stable connection between the guide rail 145 and the rotating drum 141 and reducing the structural volume. In other embodiments, the guide rail 145 can also be secured to the rotating drum 141 by welding, clamping, bonding, or other methods. The guide rail 145 can be made of a material with a certain degree of hardness, such as metal or plastic, to better achieve its guiding function.

[0183] The guide rail 145 may include two ridges 1451, each of which is spirally shaped and disposed opposite each other, with a guide groove 1452 formed between the two ridges 1451. In this case, the guide groove 1452 is also spirally shaped, and the spiral shape of the guide groove 1452 corresponds to the spiral shape of the guide rail 145. The guide rail 145 is composed of two ridges 1451, which is simple in structure, compact in size, and easy to process.

[0184] The guide rail 145 has a bottom end 145a and a top end 145b. In the axial direction of the drum 141, the top end 145b of the guide rail 145 is higher than the bottom end 145a of the guide rail 145. At the bottom end 145a and the top end 145b of the guide rail 145, two protrusions 1451 are chamfered on one side near the guide groove 1452 to expand the inlet and outlet of the guide groove 1452 and facilitate the entry and exit of other structural components into and out of the guide groove 1452.

[0185] Illustratively, the turntable 146 surrounds the outer periphery of the rotating drum 141 and is located on the bottom side of the guide rail 145. The turntable 146 is fixedly connected to the rotating drum 141. The turntable 146 and the rotating drum 141 may be integrally formed components to provide a more stable connection between the guide rail 145 and the rotating drum 141. In other embodiments, the turntable 146 may be fixed to the rotating drum 141 by welding, clamping, bonding, or other methods. The turntable 146 may be made of a material with a certain degree of hardness, such as metal or plastic.

[0186] The outer periphery of the rotating disk 146 is provided with a tooth portion 1461, and the multiple teeth of the tooth portion 1461 can be continuously arranged around. The external structural member can drive the rotating disk 146 to rotate by engaging the tooth portion 1461 of the rotating disk 146, thereby driving the rotating member 14 to rotate.

[0187] The rotating disk 146 has an inlet and outlet hole 1462. The inlet and outlet hole 1462 extends through the rotating disk 146 along the axial direction of the rotating drum 141, connecting the top and bottom spaces of the rotating disk 146. The inlet and outlet hole 1462 can be located on the side of the rotating disk 146 close to the rotating drum 141 and can be arc-shaped, partially surrounding the rotating drum 141.

[0188] For example, for the adjacent first and second meshing groups 142, 142b, in the plurality of meshing groups 142, the first meshing group 142a corresponds to the entry and exit holes 1462, while the second meshing group 142b is staggered from the entry and exit holes 1462 in the circumferential direction of the rotating member 14. The bottom end 145a of the guide rail 145 is located between the entry and exit holes 1462 and the second meshing group 142b. In this case, the bottom end 145a of the guide rail 145 is located near the entry and exit holes 1462.

[0189] The turntable 146 may further include a counterweight hole 1463 for adjusting the center of gravity of the rotating member 14. For example, the counterweight hole 1463 may be spaced apart from the inlet and outlet holes 1462, and the counterweight hole 1463 may be arc-shaped. In other embodiments, the turntable 146 may also include a counterweight block (not shown) for adjusting the center of gravity of the rotating member 14. Alternatively, the turntable 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.

[0190] In some examples, the rotating drum 141, the plurality of jackscrew posts 1421, and the rotating disk 146 can be integrally formed as an inner rotor, and the connecting ring 143, the plurality of engaging posts 1422, and the plurality of connecting posts 144 can be integrally formed as an outer rotor. The outer rotor and the inner rotor are fixedly connected 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 or bonding, which is not strictly limited in the present embodiment.

[0191] Please refer to Figures 12A to 12C. Figure 12A is a structural schematic diagram of the base 111 and the drive assembly 15 shown in Figure 10 after being assembled with the rotating member 14 shown in Figure 11A. Figure 12B is a structural schematic diagram of the structure shown in Figure 12A at another angle. Figure 12C is a schematic diagram of the internal structure of the shell 11, the drive assembly 15 and the rotating member 14 shown in Figure 5 after being assembled.

[0192] In some embodiments, the rotating member 14 is positioned within the housing 11 and surrounds the mounting space 11a. The rotating member 14 is rotatably connected to the housing 11. For example, the rotating drum 141 of the rotating member 14 can be mounted on the outer periphery of the inner sidewall 1112 of the base 111. The rotating drum 141 is rotatably connected to the housing 11. Furthermore, the rotating disk 146 of the rotating member 14 can be mounted in the recess 111d of the base 111. The rotating disk 146 is also rotatably connected to the housing 11.

[0193] The rotating member 14 can rotate relative to the housing 11 about a central axis 14o. The central 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 drum 141. The notch 111b provided in the inner sidewall 1112 reduces the contact area between the rotating drum 141 and the inner sidewall 1112. This reduces the friction area during relative motion between the rotating drum 141 and the inner sidewall 1112 while ensuring connection reliability, thereby reducing friction.

[0194] The drive 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 turret tooth 1523 can be at least partially located in the recessed groove 111d of the base 111 to engage with the rotating disk 146. When the drive member 151 is in operation, the second tooth portion 15232 of the second turret tooth 1523 drives the rotating disk 146 to rotate, thereby driving the rotating member 14 to rotate.

[0195] As shown in FIG12C , the first storage chamber 111 c is located between the turntable 146 and the housing 11, and on the bottom side of the turntable 146. The inlet and outlet holes 1462 of the turntable 146 connect to the first storage chamber 111 c. At this point, the first storage chamber 111 c can connect to the space on the top side of the turntable 146 through the inlet and outlet holes 1462 of the turntable 146. The guide rail 145 and the meshing group 142 of the rotating member 14 are located on the top side of the first storage chamber 111 c. The second storage chamber 112 b is located between the rotating member 14 and the housing 11, and surrounds the outer periphery of the rotating member 14. For example, the second storage chamber 112 b can be located on the outer periphery of the guide rail 145 and the meshing 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 periphery of the top wall 1121 of the housing 11, forming a gap between the rotating drum 141 and the inner side surface of the top wall 1121.

[0196] Please refer to FIG. 13 and FIG. 14 . FIG. 13 is a schematic structural diagram of the lifting member 12 shown in FIG. 5 , and FIG. 14 is a schematic structural diagram of the lifting member 12 shown in FIG. 13 in another use state.

[0197] In some embodiments, the cross-band 121 of the lifting member 12 is spirally shaped and elastic. The elasticity of the cross-band 121 primarily refers to its structure being elastic and capable of deformation. The cross-band 121 has a spiral central axis 121o and extends in a spiral arrangement around the spiral central axis 121o. The cross-band 121 is elastic in a direction parallel to the spiral central axis 121o, capable of deformation, stretching and compressing, in a direction parallel to the spiral central axis 121o. The axial dimension of the cross-section of the cross-band 121 is smaller than its radial dimension. For example, the cross-section of the cross-band 121 is flat, with the longer side of the cross-section oriented radially. The cross-section of the cross-band 121 is perpendicular to its extension direction. The axial direction of the cross-band 121 is parallel to the spiral central axis 121o, and the radial direction of the cross-band 121 is perpendicular to the axial direction of the cross-band 121. In this case, the cross-band 121 is more susceptible to deformation in its axial direction. The horizontal strip 121 may be in a right-handed spiral structure or a left-handed spiral structure. In the embodiment of the present application, the horizontal strip 121 is illustrated as being in a right-handed spiral structure.

[0198] The transverse band 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. The connecting portion 1211 of the transverse band 121 forms the main structure of the transverse band 121, which surrounds the spiral center axis 121o and is spiral-shaped. The outer end surface of the connecting portion 1211 is arranged to face away from the spiral center axis 121o. The tooth portion 1212 of the transverse band 121 includes a plurality of spaced teeth, and the plurality of teeth surround the spiral center axis 121o and are arranged in a spiral shape along the connecting portion 1211. The shape of the teeth may be rectangular teeth. In some other embodiments, the shape of the teeth may also be trapezoidal, triangular or other shapes, which is not strictly limited in the embodiments of the present application.

[0199] In some embodiments, the longitudinal strip 122 of the lifting member 12 is in a coiled shape and is elastic. The elasticity of the longitudinal strip 122 primarily refers to the elasticity of the structure of the longitudinal strip 122, which allows for deformation. The longitudinal strip 122 has a coiling axis 122o, around which the longitudinal strip 122 is coiled. The longitudinal strip 122 is elastic in a direction perpendicular to the coiling axis 122o, and can deform inward and outward in a direction perpendicular to the coiling axis 122o. The axial dimension of the cross-section of the longitudinal strip 122 is greater than the radial dimension of the longitudinal strip 122. For example, the cross-section of the longitudinal strip 122 is narrow and tall, with the long side of the cross-section being axially oriented. The cross-section of the longitudinal strip 122 is the shape of the cross-section perpendicular to its extension direction. The axial direction of the longitudinal strip 122 is a direction parallel to the coiling axis 122o, and the radial direction of the longitudinal strip 122 is perpendicular to the axial direction of the longitudinal strip 122. At this time, the longitudinal belt 122 is more likely to be deformed in its radial direction.

[0200] The longitudinal belt 122 can also be elastic in a direction parallel to the winding center axis 122o, and can be deformed in a direction parallel to the winding center axis 122o to perform stretching and compression.

[0201] The longitudinal strip 122 may 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. The first hole group 1221 and the second hole group 1222 each include a plurality of through holes spaced apart along the extension direction of the longitudinal strip 122. The through holes of the first hole group 1221 and the through holes of the second hole group 1222 may be arranged opposite each other in a direction parallel to the winding center axis 122o, or may be staggered.

[0202] In some embodiments, a portion of the horizontal belt 121 engages with a portion of the vertical belt 122, and the engaged portion (hereinafter referred to as the engaged section) can vary. The lifting member 12 can have a first state and a second state. The first state can correspond to an initial state, in which the engaged section between the horizontal belt 121 and the vertical belt 122 is shorter. The second state can correspond to a fully engaged state, in which the engaged section between the horizontal belt 121 and the vertical belt 122 is longer.

[0203] The transverse strap 121 and the longitudinal strap 122 can each be divided into a storage section (121a / 122a), an engagement section (121b / 122b), and a transition section (121c / 122c) based on their current assembly configuration. The storage section (121a / 122a) is the portion in the initial storage state, the engagement section (121b / 122b) is the engagement section, and the transition section (121c / 122c) is the portion connecting the storage section (121a / 122a) and the engagement section (121b / 122b). The top section of the transverse strap 121 and the innermost section of the longitudinal strap 122 can always remain in an engaged state, and are the engagement section (121b / 122b). The bottom section of the transverse strap 121 and the outermost section of the longitudinal strap 122 can always remain in an undeformed state, and are the storage section (121a / 122a). The pitch of the meshing section 121b of the transverse belt 121 is greater than the pitch of the storage section 121a of the transverse belt 121. The pitch refers to the axial distance between two adjacent sections of the transverse belt 121 in the axial direction.

[0204] During the process of the lifting member 12 changing from the first state to the second state: the meshing section 121b of the transverse belt 121 and the meshing section 122b of the longitudinal belt 122 rise; the transition section 121c of the transverse belt 121 rises, and the transition section 122c of the longitudinal belt 122 rolls inward and gradually engages with the transition section 121c of the transverse belt 121, and after the two are engaged, they are converted into the meshing section (121b / 122b); the storage section 121a of the transverse belt 121 is partially converted into the transition section 121c and rises, and the storage section 122a of the longitudinal belt 122 is partially converted into the transition section 122c and rolls inward.

[0205] During the process of the lifting member 12 changing from the second state to the first state: the meshing section 121b of the transverse belt 121 and the meshing section 122b of the longitudinal belt 122 descend, and the partial meshing section 121b of the transverse belt 121 and the partial meshing section 122b of the longitudinal belt 122 gradually separate and are converted into a transition section (121c / 122c); the transition section 121c of the transverse belt 121 descends and is gradually converted into the storage section 121a, and the transition section 122c of the longitudinal belt 122 expands outward and is gradually converted into the storage section 122a; the length of the storage section 121a of the transverse belt 121 becomes longer, and the length of the storage section 122a of the longitudinal belt 122 becomes longer.

[0206] Exemplarily, as shown in FIG14 , in the meshing section (121b / 122b) between the transverse belt 121 and the longitudinal belt 122, the longitudinal belt 122 may include a first section 1223 and a second section 1224. The first section 1223 and the second section 1224 of the longitudinal belt 122 are adjacent in the axial direction of the longitudinal belt 122, the bottom of the first section 1223 overlaps with the top of the second section 1224, and the tooth portion 1212 of the transverse 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. The first section 1223 and the second section 1224 of the longitudinal belt 122 may respectively be a section of the belt body or a full circle of the belt body located in two adjacent circles of the longitudinal belt 122, and the first section 1223 and the second section 1224 are aligned in the axial direction of the longitudinal belt 122.

[0207] In this embodiment, in the meshing section of the transverse belt 121 and the longitudinal belt 122, since the two adjacent circles of the transverse belt 121 and the longitudinal belt 122 are meshed, the two adjacent circles of the transverse belt 121 can be supported by the same circle of the longitudinal belt 122 to maintain the relative position relationship between the two adjacent circles of the transverse belt 121, so that the meshing section of the transverse belt 121 and the longitudinal belt 122 can maintain a stable structure in the axial direction of the lifting member 12 to have a stable height.

[0208] It is understandable that in some other embodiments, the transverse belt 121 and the longitudinal belt 122 of the lifting member 12 may also have other assembly structures such as engaging structures and supporting structures, and the embodiments of the present application do not strictly limit this.

[0209] Please refer to Figures 15A and 15B in combination. Figure 15A is a schematic diagram of the assembly structure of the structure shown in Figure 12A and the horizontal belt 121 shown in Figure 13, and Figure 15B is a schematic diagram of the structure shown in Figure 15A in another use state.

[0210] In some embodiments, the horizontal band 121 is mounted on the rotating member 14 and the housing 11. For example, a portion of the horizontal band 121 is wrapped around the rotating member 14, while another portion of the horizontal band 121 is located on the bottom side of the rotating member 14 and housed within the housing 11. The spiral axis 121o of the horizontal band 121 may correspond to the rotation axis 14o of the rotating member 14, and the two may overlap. Even if the spiral axis 121o of the horizontal band 121 and the rotation axis 14o of the rotating member 14 do not overlap due to a small deviation due to manufacturing or assembly tolerances, the two are still considered to be in an overlapping state.

[0211] For example, a portion of the horizontal band 121 can be mounted on the guide rail 145 of the rotating member 14 along the extension direction of the guide rail 145, with the horizontal band 121 slidably connected to the guide rail 145. This portion of the horizontal band 121 passes through the engagement gap 1423 of the engagement assembly 142 of the rotating member 14. Furthermore, the horizontal band 121 can be partially positioned within the guide groove 1452 of the guide rail 145 to better mate with the guide rail 145. The connecting portion 1211 of the horizontal band 121 can be mounted on the guide rail 145, and the teeth 1212 of the horizontal band 121 can be positioned toward the engagement post 1422.

[0212] For example, another portion of the horizontal belt 121 can pass through the inlet and outlet hole 1462 of the rotating disk 146 and extend into the first storage cavity 111c at the bottom side of the rotating member 14. At this time, the horizontal belt 121 passes through the inlet and outlet hole 1462 of the rotating disk 146 and is partially located in the first storage cavity 111c.

[0213] In this embodiment, when the drive assembly 15 drives the rotating member 14 to rotate, the guide rail 145 rotates and drives the transverse belt 121 mounted on the guide rail 145 to move, thereby raising and lowering the transverse belt 121. For example, when the drive assembly 15 drives the rotating member 14 to rotate clockwise, the guide rail 145 drives the transverse belt 121 to rise, wherein a portion of the transverse belt 121 can extend from the first storage cavity 111c, enter the guide rail 145, and then rise to the top side of the guide rail 145. When the drive assembly 15 drives the rotating member 14 to rotate counterclockwise, the guide rail 145 drives the transverse belt 121 to descend, wherein a portion of the transverse belt 121 located on the top side of the guide rail 145 can enter the guide rail 145, then exit the guide rail 145 and enter the first storage cavity 111c.

[0214] Please refer to Figures 16A to 16D in combination. Figure 16A is a schematic diagram of the assembly structure of the structure shown in Figure 12A and the lifting member 12 shown in Figure 13. Figure 16B is a schematic diagram of the internal structure after the shell 11, drive assembly 15, rotating member 14 and lifting member 12 shown in Figure 5 are assembled. Figure 16C is a schematic diagram of the structure shown in Figure 16A in another usage state. Figure 16D is a schematic diagram of the structure shown in Figure 16B in another usage state.

[0215] In some embodiments, the longitudinal belt 122 is mounted on the rotating member 14 and the housing 11. Exemplarily, a portion of the longitudinal belt 122 is wound around the rotating member 14 and engages with the transverse belt 121, and another portion of the longitudinal belt 122 is located on the outer peripheral side of the rotating member 14 and is accommodated in the housing 11. The winding center axis 122o of the longitudinal belt 122 may correspond to the rotation center 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 engage with the transverse belt 121 at the meshing gap 1423. For example, the longitudinal belt 122 may engage with the transverse belt 121 at the second meshing group 142b. The longitudinal belt 122 also passes through the space between the meshing column 1422a of the first meshing group 142a and the meshing column 1422b of the second meshing group 142b, and is partially located in the second storage cavity 112b.

[0216] In this embodiment, the drive assembly 15 drives the rotating member 14 to rotate, which in turn drives the transverse belt 121 and the longitudinal belt 122 to move, thereby causing the lifting member 12 to rise and fall. Figures 16A and 16B correspond to the structure of the lifting mechanism 1 in the retracted state, in which the lifting member 12 is in the first state; Figures 16C and 16D correspond to the structure of the lifting mechanism 1 in the extended state, in which the lifting member 12 is in the second state.

[0217] In some examples, when the driving assembly 15 drives the rotating member 14 to rotate clockwise, the guide rail 145 drives the transverse belt 121 to rise, a portion of the longitudinal belt 122 engages with the transverse belt 121 and rises with the transverse belt 121, and the lifting mechanism 1 can be transformed from a retracted state to an extended state. Among them, a part of the transverse belt 121 can rise upward from the first storage cavity 111c, pass through the inlet and outlet hole 1462 of the turntable 146, and enter the guide rail 145 of the rotating part 14; a part of the longitudinal belt 122 can shrink inward from the second storage cavity 112b, pass through the space between the engaging column 1422a of the first engaging group 142a and the engaging column 1422b of the second engaging group 142b, enter the rotating part 14, and engage with the transverse belt 121 in the engaging gap 1423 of the engaging group 142 (for example, the second engaging group 1422b) of the rotating part 14, and the engaging part of the transverse belt 121 and the longitudinal belt 122 rise to the top side of the guide rail 145.

[0218] When the driving assembly 15 drives the rotating member 14 to rotate counterclockwise, the guide rail 145 drives the transverse belt 121 to descend, and a portion 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 transformed from the extended state to the retracted state. In particular, the meshing section of the transverse belt 121 and the longitudinal belt 122 can descend. Between the first meshing group 142a and the second meshing group 142b, a portion of the transverse belt 121 disengages from the guide rail 145 at the bottom end, passes through the inlet and outlet hole 1462 of the rotating disk 146, and enters the first storage cavity 111c. A portion of the longitudinal belt 122 disengages from the transverse belt 121, then expands outward, passes through the space between the meshing column 1422a of the first meshing group 142a and the meshing column 1422b of the second meshing group 142b, and enters the second storage cavity 112b. The transverse belt 121 and the longitudinal belt 122 are completely separated at the position corresponding to the second meshing group 142b.

[0219] Among them, the last circle of the transverse belt 121 located in the first storage cavity 111c (that is, the circle at the bottom) can be fixedly connected to the shell 11, so that during the lifting process, the transverse belt 121 mainly moves along the axial direction of the rotating part 14, and there is less displacement in the circumferential direction of the rotating part 14, so that when the rotating part 14 rotates, it can better drive the transverse belt 121 to perform axial lifting and lowering, thereby ensuring the accuracy and reliability of the driving action.

[0220] Among them, the last circle of the longitudinal belt 122 located in the second storage cavity 112b (that is, the outermost circle) can be fixedly connected to the shell 11, so that the longitudinal belt 122 mainly moves along the radial direction of the rotating part 14 during the process of shrinking or expanding, and there is less displacement in the circumferential direction of the rotating part 14, so that the rotating part 14 can better drive the longitudinal belt 122 to shrink or expand when rotating, so as to ensure the accuracy and reliability of the driving action.

[0221] Please refer to FIG. 16B and FIG. 17 in combination. FIG. 17 is a top view of the structure shown in FIG. 16A .

[0222] In some embodiments, the top screw posts 1421 of the meshing group 142 abut against the transverse belt 121, forming a gap between the transverse belt 121 and the outer side surface of the rotating drum 141. In this embodiment, the top screw posts 1421 abut against the transverse belt 121, so that a gap is formed between the transverse belt 121 and the outer side surface of the rotating drum 141. The transverse belt 121 contacts the surfaces of the top screw posts 1421 of the meshing group 142 but does not contact the outer side surface of the rotating drum 141, thereby reducing the contact area between the transverse belt 121 and the rotating member 14, thereby reducing the friction between the transverse belt 121 and the rotating member 14 when the transverse belt 121 moves relative to the rotating member 14, thereby reducing the friction loss between the rotating member 14 and the transverse belt 121, and also facilitating the reduction of power consumption of the lifting mechanism 1.

[0223] The engagement post 1422 abuts against the longitudinal strap 122. The engagement post 1422 cooperates with the screw post 1421 to engage and connect the longitudinal strap 122 to the transverse strap 121, maintaining a stable connection and preventing radial movement between the longitudinal strap 122 and the transverse strap 121. This improves the reliability of the lifting member 12 and the lifting mechanism 1. When the rotor rotates clockwise, the engagement post 1422 drives the longitudinal strap 122 to move radially from the second storage chamber 112b toward the rotating member 14, causing it to retract inward and engage with the transverse strap 121, tightly meshing with the transverse strap 121.

[0224] In the process of the rotating part 14 driving the lifting part 12 to rise, after the transverse belt 121 extends from the first storage cavity 111c and the longitudinal belt 122 extends from the second storage cavity 112b, the two can engage at the second engaging group 142b of the rotating part 14, and then enter the third engaging group 142c and the fourth engaging group 142d in turn to maintain a stable engaging relationship, and the longitudinal belt 122 and the transverse belt 121 can rise synchronously.

[0225] In some embodiments, as shown in FIG16B , the avoidance groove 1424 on the engagement post 1422 is used to avoid the transverse belt 121. In this case, the engagement post 1422 can maintain abutment against the longitudinal belt 122, and also, through the recessed avoidance groove 1424, allow the teeth 1212 of the transverse belt 121 to have a greater height. For example, the height of the teeth 1212 of the transverse belt 121 can exceed the thickness of the longitudinal belt 122, thereby better maintaining a stable engagement relationship with the longitudinal belt 122.

[0226] In the embodiment of the present application, the lifting mechanism 1 forms a set of small-volume spiral guide structure and meshing structure through the structural design of the rotating part 14 and the lifting part 12 and the matching structure design of the two. The spiral guide structure can realize the lifting part 12 of the elastic part to be driven to rise and fall in a small space, and the meshing structure can make the horizontal belt 121 and the vertical belt 122 of the lifting part 12 tightly fit together, thereby improving the movement stability of the lifting mechanism 1.

[0227] In the embodiment of the present application, during the lifting process of the lifting mechanism 1, mutual friction occurs between the lifting part 12 and the rotating part 14. The lifting mechanism 1 provides a wear-resistant layer at the friction position to improve the wear resistance of the lifting mechanism 1 and improve the reliability of the lifting mechanism 1.

[0228] For example, the surface of the guide rail 145 contacting the transverse belt 121 and / or the surface of the transverse belt 121 contacting the guide rail 145 may be provided with a wear-resistant layer (not shown). The wear-resistant performance of the wear-resistant layer may be higher than the wear-resistant performance of the main body of the guide rail 145 and the main body of the transverse belt 121. The surface of the guide rail 145 contacting the transverse belt 121 may be located on the wall surface of the guide groove 1452 of the guide rail 145; the surface of the transverse belt 121 contacting the guide rail 145 may be located on the outer surface of the connecting portion 1211 of the transverse belt 121.

[0229] In this embodiment, by providing a wear-resistant layer at the friction position of at least one of the guide rail 145 and the transverse belt 121 , the friction loss between the guide rail 145 and the transverse belt 121 can be reduced, which is beneficial to improving the reliability of the lifting mechanism 1 .

[0230] For example, one or more of the surface of the jackscrew post 1421 facing the engagement post 1422, the surface of the engagement post 1422 facing the jackscrew post 1421, the surface of the longitudinal strip 122 contacting the jackscrew post 1421, the surface of the longitudinal strip 122 contacting the transverse strip 121, and the surface of the transverse strip 121 contacting the longitudinal strip 122 may be provided with a wear-resistant layer. The wear-resistant performance of the wear-resistant layer may be higher than the wear-resistant performance of the structural body.

[0231] In this embodiment, by providing a wear-resistant layer at at least one of the friction positions between the top screw column 1421 and the longitudinal belt 122, the friction position between the engaging column 1422 and the longitudinal belt 122, and the friction position between the transverse belt 121 and the longitudinal belt 122, the friction loss between the rotating part 14 and the lifting part 12 can be reduced, thereby improving the reliability of the lifting mechanism 1.

[0232] For example, the wear-resistant layer may be a diamond-like carbon layer. The wear-resistant layer may be formed using thin film deposition technology. Alternatively, the wear-resistant layer may be a metal nitriding layer or a metal sulfiding layer. The wear-resistant layer may be formed by performing a nitriding or sulfiding process on the surface of a structural part made of a metal material. In other embodiments, the wear-resistant layer may also have other structures or materials, which are not strictly limited in the present embodiment.

[0233] In the embodiment of the present application, the lifting member 12 can also make the center of gravity of the rotating member 14 located on the rotation center axis 14o of the rotating member 14 through the counterweight hole 1463 (see Figure 11A) on the turntable 146 of the rotating member 14 and / or the setting of the counterweight block.

[0234] 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 central axis of rotation 14o of the rotating member 14. This can reduce the risk of the rotating member 14 rotating when the lifting mechanism 1 falls, thereby helping to ensure the reliability of the mechanism. In addition, the center of gravity of the rotating member 14 is located on the central axis of rotation 14o of the rotating member 14, which means that the rotating member 14 will not be overweight during rotation, or the overweight will be very slight, thereby avoiding the problem of excessive wear in localized areas of the rotating member 14 (during the friction process, the wear of certain locations in the structural member is generally significantly greater than the wear of lighter locations). This helps to extend the service life of the rotating member 14 and improve the reliability of the rotating member 14 and the lifting mechanism 1.

[0235] Please refer to FIG. 18 , which is a schematic structural diagram of the decorative element 13 shown in FIG. 5 .

[0236] In some embodiments, the decorative member 13 includes a fixing ring 131 and a light-transmitting sheet 132. A through-hole 1311 is formed on the inner side of the fixing ring 131. The fixing ring 131 has a recessed groove 1312 opening toward the top, which surrounds the through-hole and communicates with the through-hole 1311. The fixing ring 131 may also have a recessed groove 1313 opening toward the bottom and a fixing groove 1314. The recessed groove 1313 surrounds the through-hole 1311 and is spaced apart from the through-hole 1311. The recessed groove 1313 may also surround the recessed groove 1312. The fixing groove 1314 surrounds the recessed groove 1313.

[0237] The light-transmitting sheet 132 can be made of a translucent material, for example, a translucent lens. The light-transmitting sheet 132 can be fixed to the inner periphery of the fixing ring 131 and cover the inner through-hole (i.e., through-hole 1311) of the fixing ring 131. For example, the light-transmitting sheet 132 can be partially located in the recessed groove 1312 of the fixing ring 131 and fixedly connected to the bottom wall of the recessed groove 1312 via an adhesive layer 133.

[0238] Please refer to FIG. 19A , which is a schematic cross-sectional view of the lifting mechanism 1 of the camera device 30 shown in FIG. 2A taken along line AA.

[0239] In some embodiments, the decorative member 13 is located on the top side of the housing 11, and the periphery of the decorative member 13 is fixedly connected to the longitudinal strap 122. For example, the decorative member 13 can be connected to the longitudinal strap 122 via the outer periphery of a fixing ring 131. The longitudinal strap 122 can be inserted into the fixing groove 1314 of the fixing ring 131 to increase the stability and firmness of the connection between the longitudinal strap 122 and the decorative member 13. The longitudinal strap 122 and the decorative member 13 can be fixed to each other by gluing or other connecting methods.

[0240] In this embodiment, the decorative member 13 is located on the top side of the shell 11, and the light-transmitting sheet 132 of the decorative member 13 is arranged corresponding to the installation space 11a of the shell 11, so that light on the top side of the lifting mechanism 1 can pass through the light-transmitting sheet 132 and enter the installation space 11a.

[0241] Please refer to FIG. 19A and FIG. 19B . FIG. 19B is a schematic structural diagram of the lifting mechanism 1 shown in FIG. 19A in another use state.

[0242] In some embodiments, in the lifting mechanism 1, when the drive assembly 15 drives the rotating member 14 to rotate forward, the transverse belt 121 engages with the longitudinal belt 122 and rises, raising the decorative member 13. When the drive assembly 15 drives the rotating member 14 to rotate reversely, the transverse belt 121 and the longitudinal belt 122 descend and separate, lowering the decorative member 13. The terms "forward rotation" and "reverse rotation" do not strictly define the specific rotational directions they correspond to; they are opposite rotational directions. Forward rotation corresponds to the rotational direction of the rotating member 14 that drives the lifting member 12 to rise, while reverse rotation corresponds to the rotational direction of the rotating member 14 that drives the lifting member 12 to descend.

[0243] In the embodiment of the present application, the lifting mechanism 1 drives the rotating member 14 to rotate through the driving component 15. When the rotating member 14 rotates, the horizontal belt 121 can be lifted or retracted, and at the same time the longitudinal belt 122 is pressed to engage with the horizontal belt 121 or separate from the horizontal belt 121 to achieve the raising or lowering of the decorative member 13, thereby meeting the purpose of having sufficient optically available space for the camera module 2 when the decorative member 13 is raised, and also meeting the purpose of having a small overall height of the camera device 30 when the decorative member 13 is lowered.

[0244] In addition, the transverse belt 121 and the longitudinal belt 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 belt 121 and the longitudinal belt 122 of the lifting member 12 has a high degree of freedom in design, and the number of turns of the transverse belt 121 and the longitudinal belt 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 limit 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.

[0245] 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.

[0246] 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.

[0247] In some embodiments, as shown in Figures 19A and 19B, the top end of the first waterproof member 161 of the waterproof assembly 16 can be sealed to the periphery of the decorative member 13, and the other end of the first waterproof member 161 is used to seal 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 has 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 can have 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.

[0248] The first waterproof member 161 can be made of materials such as rubber. The waterproof assembly 16 can also include a first fixing ring 163 and a second fixing ring 164, wherein 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. 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 through an insert injection molding process. Alternatively, 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.

[0249] The first fixing ring 163 and the decorative member 13 can be fixed by glue or other methods. The second fixing ring 164 and the camera module 2 (see FIG. 2B ) can be fixed by glue or other methods.

[0250] In this embodiment, the periphery of the decorative component 13 and the camera module 2 are sealed and connected by the first waterproof component 161, which can reduce the risk of external water vapor, dust, etc. entering the light incident surface of the camera module 2, thereby improving the waterproof and dustproof performance of the camera device 30, which is conducive to ensuring the shooting quality of the camera device 30.

[0251] In some embodiments, as shown in Figures 19A and 19B , the longitudinal belt 122 of the lifting member 12 passes through the top wall 1121 of the housing 11. The top wall 1121 of the housing 11 has an inner side facing the longitudinal belt 122. The second waterproof member 162 of the waterproof assembly 16 is annular and fixed to the inner side of the top wall 1121 of the housing 11, and abuts the longitudinal belt 122.

[0252] The second waterproof member 162 can be made of rubber or other materials. The second waterproof member 162 can be fixed to the housing 11 by injection molding, or the second waterproof member 162 can be fixed to the housing 11 by bonding or other methods, which is not strictly limited in this embodiment of the present application.

[0253] In this embodiment, the second waterproof member 162 seals the gap between the longitudinal belt 122 and the housing 11 , thereby reducing the risk of external moisture, dust, etc. entering the interior of the lifting structure, thereby improving the reliability of the lifting mechanism 1 and the camera device 30 .

[0254] Please refer to FIG. 20 , which is another schematic diagram of the camera device 30 shown in FIG. 2B .

[0255] In some examples, the camera device 30 and lifting assembly of the present invention can achieve a miniaturized design. For example, while meeting lifting requirements and accommodating the camera module 2, the lifting mechanism 1 can have a height h1 and a width W. The height h1 can be within a range of 8 mm to 12.5 mm, such as 10.2 mm, 10.7 mm, or 11.2 mm, and the width W can be within a range of 30 mm to 42 mm, such as 32 mm, 36 mm, or 40 mm. The main portion of the lifting mechanism 1 can have a shoulder height h2, which can be within a range of 7 mm to 9.2 mm, such as 7.8 mm, 8.1 mm, or 8.3 mm. The diameter D1 of the installation space 11a of the lifting mechanism 1 can be within a range of 20 mm to 26 mm, such as 21 mm, 23 mm, or 24 mm. The diameter D2 of the light-transmitting area of ​​the decorative member 13 (corresponding to the inner through-hole 1311 of the fixing ring 131 in FIG. 18 ) can be in the range of 12 mm to 18 mm, for example, 13 mm, 15 mm, 17 mm, etc. The diameter D3 of the decorative member 13 can be in the range of 25 mm to 35 mm, for example, 27 mm, 30 mm, 33 mm, etc. The height H of the camera assembly 30 can be in the range of 10 mm to 13.2 mm, for example, 27 mm, 30 mm, 33 mm, etc.

[0256] In some embodiments, the height of the lifting mechanism 1 is smaller than the width of the lifting mechanism 1. In this embodiment, the height of the lifting mechanism 1 is smaller and the width is larger. When the lifting mechanism 1 is used in the electronic device 100, the height of the lifting mechanism 1 corresponds to the thickness direction of the electronic device 100, and the width of the lifting mechanism 1 can correspond to the width direction or the length direction of the electronic device 100. Therefore, the lifting mechanism 1 and the camera device 30 are more suitable for use in thin electronic devices 100.

[0257] Please refer to FIG. 21 , which is another schematic diagram of the camera device 30 shown in FIG. 3A .

[0258] In some examples, the decorative part 13 of the lifting mechanism 1 is in a dotted position when retracted and in a solid position when extended. The lifting stroke S of the decorative part 13 can be in the range of 9 mm to 12.5 mm, for example, 9.8 mm, 10.65 mm, 11 mm, etc.

[0259] In some embodiments, the ratio of the lifting stroke of the decorative member 13 to the height of the lifting mechanism 1 can be greater than or equal to 0.8, or greater than or equal to 1. In this embodiment, by adjusting the number of turns of the transverse belt 121 and the longitudinal belt 122 of the lifting member 12, the lifting member 12 has a high compression ratio, and the lifting stroke of the lifting member 12 can be flexibly adjusted so that the lifting stroke approaches or exceeds the height of the lifting mechanism 1, thereby enabling the lifting mechanism 1 to better achieve a large lifting stroke.
