Description

Technical Field

[0001] This application relates to the field of electronic devices, and in particular to a camera decorative component, electronic device, and lifting device. Background Technology

[0002] With continuous technological advancements, cameras in electronic devices have gradually evolved into pop-up, retractable cameras. These cameras can rise and retract relative to the device's casing. Simultaneously, camera decorative elements also need to be compatible with these pop-up, retractable cameras, possessing the ability to rise and retract relative to the casing. Typically, these decorative elements achieve their lifting function through a lifting mechanism. However, current lifting mechanisms are structurally complex and costly to manufacture, and the lifting stroke of the camera decorative elements is relatively small, failing to meet usage requirements. Summary of the Invention

[0003] This application provides a camera decorative component, an electronic device, and a lifting device, aiming to provide a lifting device with a relatively simple structure, low manufacturing cost, and large lifting stroke, a camera decorative component including the lifting device, and an electronic device including the camera decorative component.

[0004] In a first aspect, a camera decorative assembly is provided. The camera decorative assembly includes a camera decorative piece, a base, a drive mechanism, a first rocker arm, a first swing arm, and a mounting block. The first rocker arm includes a first end and a second end, the first end being rotatably connected to the base, and the second end being spaced apart from the base. The first swing arm includes a first end, a second end, and a first movable portion located between the first end and the second end. The first end is slidably connected to the base, the second end being rotatably connected to the mounting block, and the first movable portion is movably connected to the first rocker arm and spaced apart from the first end. The drive mechanism is connected to the first rocker arm and is used to drive the first rocker arm to rotate relative to the base. The camera decorative piece is mounted on the mounting block. The camera decorative assembly includes a first state and a second state. When the camera decorative assembly is in the first state, the distance between the mounting block and the base is a first gap; when the camera decorative assembly is in the second state, the distance between the mounting block and the base is a second gap. The first gap is smaller than the second gap. When the camera decorative assembly switches between the first state and the second state, the distance between the mounting block and the base changes.

[0005] It is understandable that, compared to some camera decoration components that use gears and worm gears to drive the mounting block and base, and utilize the guide rail between the base and mounting block to convert the circumferential rotation of the base into vertical lifting motion to achieve the lifting of the camera decoration, this method results in a large number of parts, higher manufacturing costs, and a smaller lifting stroke for the camera decoration. Furthermore, the transmission mechanism between the mounting block and base uses a higher pair mechanism, which has low transmission efficiency, high friction loss, and high power consumption during movement. In contrast, the camera decoration component in this embodiment connects the base and mounting block through a linkage mechanism formed by a first rocker arm and a first swing arm, i.e., a lower pair mechanism. This results in higher transmission efficiency, lower friction loss, and reduced power consumption. The linkage mechanism also increases the movement stroke of the mounting block, thus increasing the lifting stroke of the camera decoration. Additionally, the first rocker arm and first swing arm are both rods, with simple structures that are easy to manufacture, reducing manufacturing costs and simplifying the manufacturing process.

[0006] In one possible implementation, during the transition of the camera decorative assembly from a first state to a second state, the first rocker arm rotates relative to the base along a first rotation direction, the first swing arm rotates relative to the first rocker arm with the first movable part as the rotation center along a second rotation direction, and the mounting block moves relative to the base along a first direction; during the transition of the camera decorative assembly from a second state to a first state, the first rocker arm rotates relative to the base along a second rotation direction, the first swing arm rotates relative to the first rocker arm with the first movable part as the rotation center along a first rotation direction, and the mounting block moves relative to the base along a second direction; wherein, the first direction is opposite to the second direction, and the first direction is parallel to the thickness direction of the base.

[0007] In this way, by rotating the first rocker arm relative to the base in different directions, the mounting block can move relative to the base in a first or second direction under the action of the first rocker arm and the first swing arm. This allows the camera decorative component to rise in the first direction or fall in the second direction relative to the base, thus realizing the lifting and lowering movement of the camera decorative component. The overall movement of the camera decorative component is relatively simple and easy to control.

[0008] In one possible implementation, during the switching process of the camera decoration assembly from a first state to a second state, the second end of the first rocker arm displaces relative to the base along a first direction and a third direction, and the second end of the first swing arm displaces relative to the second end of the first rocker arm along a first direction and a fourth direction; during the switching process of the camera decoration assembly from a second state to a first state, the second end of the first rocker arm displaces relative to the base along a second direction and a fourth direction, and the second end of the first swing arm displaces relative to the second end of the first rocker arm along a second direction and a third direction; wherein, the third direction is opposite to the fourth direction and perpendicular to the thickness direction of the base.

[0009] In this way, when the camera decoration component switches between the first state and the second state, the rotation directions of the first rocker and the first swing arm are different. The first rocker and the first swing arm can roughly form a V-shaped structure, so that the displacement perpendicular to the first direction generated by the second end of the first swing arm relative to the first rocker when the first swing arm moves can be canceled by the displacement perpendicular to the first direction generated by the second end of the first rocker relative to the base when the first rocker moves. This can reduce the displacement perpendicular to the first direction generated by the mounting block relative to the base, which is beneficial to ensure the lifting and lowering movement of the camera decoration component along the thickness direction of the base.

[0010] In one possible implementation, during the transition of the camera decoration component from a first state to a second state, the second end of the first rocker arm experiences a first displacement relative to the base along a third direction, and the second end of the first swing arm experiences a second displacement relative to the second end of the first rocker arm along a fourth direction, with the second displacement being equal to the first displacement. The third direction is opposite to the fourth direction and perpendicular to the thickness direction of the base. In this way, the first displacement cancels out the second displacement, allowing the mounting block to move the camera decoration component linearly relative to the base along its thickness direction, achieving linear lifting and lowering.

[0011] In one possible implementation, the camera decorative assembly further includes a first connecting rod, which comprises a first connecting end and a second connecting end. The first connecting end is rotatably connected to the second connecting end, and the second connecting end is movably connected to the base. The first movable part of the first swing arm is rotatably connected to the first connecting rod. In this way, the first swing arm can be spaced apart from the first rocker arm, and a clearance space can be formed between the first swing arm and the first rocker arm to avoid the mounting block. This can prevent the drive mechanism, the first rocker arm, and other structures from affecting the light intake of the camera module, which is beneficial to ensuring the amount of light intake of the camera module.

[0012] In one possible implementation, during the switching between the first and second states of the camera decorative assembly, the second connecting end of the first link rotates relative to the base in the same direction as the rotation of the first rocker relative to the base. In this way, the first link, the first rocker, and the base can form a four-bar linkage, and the movement of the first link is relatively simple and easy to control.

[0013] In one possible implementation, the radius of rotation of the second connecting end of the first link relative to the base is equal to the length of the first rocker arm. In this way, the first link, the first rocker arm, and the base can form a parallelogram mechanism. The first link only moves relative to the base and does not rotate relative to it, making the movement of the lifting device simpler, easier to control, and reducing the difficulty of manufacturing.

[0014] In one possible implementation, the camera decoration assembly further includes a second rocker arm, which includes a first end and a second end. The first end of the second rocker arm is rotatably connected to the base, and the second end of the second rocker arm is rotatably connected to the second connecting end of the first connecting rod. The length of the second rocker arm is equal to the length of the first rocker arm. During the switching between the first state and the second state of the camera decoration assembly, the second rocker arm rotates relative to the base in the same direction as the first rocker arm rotates relative to the base.

[0015] In this way, the second connecting end of the first link can be connected to the base via the second rocker arm. The first link, the first rocker arm, the second rocker arm, and the base together form a four-bar linkage, which is simple and easy to control. At the same time, the base is rotatably connected to the second rocker arm, and the base does not need to be equipped with a sliding groove (such as an arc groove), which is conducive to reducing the thickness of the base, thereby realizing the thinner design of the camera decorative component.

[0016] In one possible implementation, the length between the first end of the first swing arm and the first movable part is a first length, and the rotation radius of the second connecting end of the first link relative to the base is equal to the first length. Thus, by setting the rotation radius of the second connecting end of the first link relative to the base to be equal to the first length, when the camera decorative assembly switches between the first and second states, the first end of the first swing arm can slide relative to the base in a straight line. The movement of the first end of the first swing arm is simple and easy to control, and it also reduces the thickness of the base, which is beneficial for achieving a thinner design for the camera decorative assembly.

[0017] In one possible implementation, the base is provided with a first sliding groove, and the first end of the first swing arm is slidably connected to the first sliding groove, which is elongated. This elongated shape of the first sliding groove effectively reduces the thickness of the base, facilitating a thinner design for the camera decorative component.

[0018] In one possible implementation, the width of the first movable part is greater than the width of the first end. This larger width of the first movable part helps prevent stress concentration that could cause the first swing arm to break, thus extending its service life.

[0019] In one possible implementation, the camera decoration assembly further includes a third rocker arm and a second swing arm. The second swing arm includes a third end, a fourth end, and a second movable part located between the third end and the fourth end. The third end is slidably connected to the base, and the fourth end is rotatably connected to the mounting block. The third rocker arm includes a first end and a second end. The first end of the third rocker arm is rotatably connected to the base, and the second end of the third rocker arm is rotatably connected to the second movable part. During the switching between the first state and the second state of the camera decoration assembly, the direction of rotation of the second swing arm relative to the third rocker arm is opposite to the direction of rotation of the third rocker arm relative to the base.

[0020] It is understandable that in this embodiment, by setting a third rocker arm and a second swing arm to cooperate with the first rocker arm and the first swing arm, the mounting block can move relative to the base along the first or second direction, which is beneficial to improving the motion stability of the mounting block. Secondly, the second swing arm and the third rocker arm rotate in opposite directions, and the second swing arm and the third rocker arm can form a V-shaped structure, so that the displacement perpendicular to the first direction generated by the fourth end of the second swing arm relative to the third rocker arm when it moves can cancel out the displacement perpendicular to the first direction generated by the second end of the third rocker arm relative to the base when it moves. This allows the fourth end of the second swing arm to move relative to the base along the first or second direction, which is beneficial to ensuring that the mounting block moves relative to the base along the first or second direction, realizing the linear lifting and lowering of the mounting block relative to the base, and ensuring the smoothness and fluidity of the lifting and lowering movement of the camera decorative part.

[0021] In one possible implementation, the length between the third end and the second movable part is equal to the length of the third rocker arm. By setting the length between the third end and the second movable part to be equal to the length of the third rocker arm, when the camera decoration assembly switches between the first and second states, the third end of the second swing arm can slide relative to the base in a straight line. The movement of the third end of the second swing arm is simple and easy to control, and it also reduces the thickness of the base, which is beneficial for achieving a thinner design for the camera decoration assembly.

[0022] In one possible implementation, during the switching between the first and second states of the camera decoration component, the first and second swing arms rotate in opposite directions. Thus, when the camera decoration component is in the second state, the opening direction of the angle between the first swing arm and the plane of the base can be opposite to the opening direction of the angle between the second swing arm and the plane of the base. The first and second swing arms can roughly form a triangular structure with the mounting block, providing good support for the mounting block.

[0023] In one possible implementation, the length of the third rocker arm is equal to the length of the first rocker arm. This way, when the camera trim assembly switches between the first and second states, the displacement of the second end of the first rocker arm relative to the base in either the first or second direction can be the same as the displacement of the second end of the third rocker arm relative to the base in either the first or second direction, thus helping to ensure the smoothness of the mounting block's lifting and lowering relative to the base.

[0024] In one possible implementation, the length of the first swing arm is equal to the length of the second swing arm. This way, when the camera trim assembly switches between the first and second states, the displacement of the second end of the first swing arm relative to the base along either the first or second direction can be the same as the displacement of the fourth end of the second swing arm relative to the base along either the first or second direction, thus helping to ensure the smoothness of the mounting block's lifting and lowering relative to the base.

[0025] Secondly, an electronic device is provided. The electronic device includes a housing, a camera module, and the aforementioned camera decorative component. The camera module is installed inside the housing, which has a light-transmitting hole. The light-inlet hole of the camera module faces the light-transmitting hole, and the camera decorative component is installed in the light-transmitting hole. The camera decorative component of the electronic device in this embodiment has a simple structure, is easy to manufacture, and has a large stroke for driving the camera decorative component to rise and fall, meeting the usage requirements.

[0026] In one possible implementation, the lens of the camera module can extend or retract relative to the light-transmitting hole. This allows the camera decorative component to be applied to a camera module with a lifting function.

[0027] Thirdly, a lifting device is provided. The lifting device includes a base; a first rocker arm, including a first end and a second end, the first end being rotatably connected to the base, and the second end being spaced apart from the base; a first swing arm, including a first end, a second end, and a first movable part located between the first end and the second end, the first end being slidably connected to the base, and the first movable part being movably connected to the first rocker arm and spaced apart from the first end; a mounting block, rotatably connected to the second end; and a drive mechanism connected to the first rocker arm, the drive mechanism being used to drive the first rocker arm to rotate relative to the base; wherein, the lifting device includes a first state and a second state, when the lifting device is in the first state, the distance between the mounting block and the base is a first gap, and when the lifting device is in the second state, the distance between the mounting block and the base is a second gap, the first gap being less than the second gap, and the distance between the mounting block and the base changing when the lifting device switches between the first state and the second state.

[0028] Understandably, compared to some lifting devices that use gear and worm gear transmissions, utilizing the guide rail between the base and the mounting block to convert the circumferential rotation of the base into vertical lifting motion to achieve the lifting of the camera decorative component, this approach results in a larger number of lifting devices, higher manufacturing costs, and a shorter lifting stroke for the mounting block. Furthermore, the use of a higher-pair mechanism leads to lower transmission efficiency, higher frictional losses, and higher power consumption during operation. In contrast, the lifting device in this embodiment connects the base and mounting block via a linkage mechanism formed by a first rocker arm and a first swing arm, i.e., a lower-pair mechanism. This results in higher transmission efficiency, lower frictional losses, and reduced power consumption. The linkage mechanism also increases the movement stroke of the mounting block, thus increasing its lifting stroke. Additionally, both the first rocker arm and the first swing arm are rods, with simple structures that are easy to manufacture, reducing manufacturing costs and simplifying the manufacturing process.

[0029] In one possible implementation, during the transition of the lifting device from a first state to a second state, the first rocker arm rotates relative to the base along a first rotation direction, the first swing arm rotates relative to the first rocker arm with the first movable part as the rotation center along a second rotation direction, and the mounting block moves relative to the base along a first direction; during the transition of the lifting device from a second state to a first state, the first rocker arm rotates relative to the base along a second rotation direction, the first swing arm rotates relative to the first rocker arm with the first movable part as the rotation center along a first rotation direction, and the mounting block moves relative to the base along a second direction; wherein the first direction is opposite to the second direction, and the first direction is parallel to the thickness direction of the base.

[0030] In this way, by rotating the first rocker arm relative to the base in different directions, the mounting block can move relative to the base in a first direction or a second direction under the action of the first rocker arm and the first swing arm. This allows the mounting block to rise relative to the base in the first direction or fall in the second direction, thus realizing the lifting and lowering movement of the camera decorative piece. The overall movement of the lifting device is relatively simple and easy to control.

[0031] In one possible implementation, during the switching process of the lifting device from the first state to the second state, the second end of the first rocker arm displaces relative to the base along a first direction and a third direction, and the second end of the first swing arm displaces relative to the second end of the first rocker arm along a first direction and a fourth direction; during the switching process of the lifting device from the second state to the first state, the second end of the first rocker arm displaces relative to the base along a second direction and a fourth direction, and the second end of the first swing arm displaces relative to the second end of the first rocker arm along a second direction and a third direction; wherein, the third direction is opposite to the fourth direction and perpendicular to the thickness direction of the base.

[0032] In this way, when the lifting device switches between the first state and the second state, the rotation directions of the first rocker arm and the first swing arm are different, and the first rocker arm and the first swing arm can roughly form a V-shaped structure. This allows the displacement perpendicular to the first direction generated by the second end of the first swing arm relative to the first rocker arm when the first swing arm moves to cancel out the displacement perpendicular to the first direction generated by the second end of the first rocker arm relative to the base when the first rocker arm moves. This reduces the displacement perpendicular to the first direction generated by the mounting block relative to the base, which is beneficial to ensuring the lifting and lowering movement of the mounting block along the thickness direction of the base.

[0033] In one possible implementation, during the transition of the lifting device from a first state to a second state, the second end of the first rocker arm experiences a first displacement relative to the base along a third direction, and the second end of the first swing arm experiences a second displacement relative to the second end of the first rocker arm along a fourth direction, the second displacement being equal to the first displacement; wherein the third direction is opposite to the fourth direction and perpendicular to the thickness direction of the base. In this way, the first displacement can cancel out the second displacement, allowing the mounting block to move linearly relative to the base along its thickness direction, achieving linear lifting.

[0034] In one possible implementation, the lifting device further includes a first connecting rod, which comprises a first connecting end and a second connecting end. The first connecting end is rotatably connected to the second connecting end, and the second connecting end is movably connected to the base. The first movable part of the first swing arm is rotatably connected to the first connecting rod. In this way, the first swing arm can be spaced apart from the first rocker arm, and a clearance space can be formed between the first swing arm and the first rocker arm to avoid the mounting block. This can prevent the drive mechanism, the first rocker arm, and other structures from affecting the light intake of the camera module, which is beneficial to ensuring the amount of light intake of the camera module.

[0035] In one possible implementation, during the switching between the first and second states of the lifting device, the second connecting end of the first link rotates relative to the base in the same direction as the rotation of the first rocker relative to the base. In this way, the first link, the first rocker, and the base can form a four-bar linkage, and the movement of the first link is relatively simple and easy to control.

[0036] In one possible implementation, the radius of rotation of the second connecting end of the first link relative to the base is equal to the length of the first rocker arm. In this way, the first link, the first rocker arm, and the base can form a parallelogram mechanism. The first link only moves relative to the base and does not rotate relative to it, making the movement of the lifting device simpler, easier to control, and reducing the difficulty of manufacturing.

[0037] In one possible implementation, the lifting device further includes a second rocker arm, which includes a first end and a second end. The first end of the second rocker arm is rotatably connected to the base, and the second end of the second rocker arm is rotatably connected to the second connecting end of the first connecting rod. The length of the second rocker arm is equal to the length of the first rocker arm. During the switching between the first state and the second state of the lifting device, the second rocker arm rotates relative to the base in the same direction as the first rocker arm rotates relative to the base.

[0038] In this way, the second connecting end of the first link can be connected to the base through the second rocker arm. The first link, the first rocker arm, the second rocker arm, and the base can together form a four-bar linkage, which is simple to move and easy to control. At the same time, the base is rotatably connected to the second rocker arm, and the base does not need to be provided with a sliding groove (such as an arc groove), which is conducive to reducing the thickness of the base, thereby realizing the thin design of the lifting device.

[0039] In one possible implementation, the length between the first end of the first swing arm and the first movable part is a first length, and the rotation radius of the second connecting end of the first link relative to the base is equal to the first length. Thus, by setting the rotation radius of the second connecting end of the first link relative to the base to be equal to the first length, when the lifting device switches between the first and second states, the first end of the first swing arm can slide relative to the base in a straight line. The movement of the first end of the first swing arm is simple and easy to control, and it also reduces the thickness of the base, which is beneficial for achieving a thinner lifting device.

[0040] In one possible implementation, the base is provided with a first sliding groove, and the first end of the first swing arm is slidably connected to the first sliding groove, which is elongated. This elongated shape of the first sliding groove effectively reduces the thickness of the base, facilitating a slimmer design for the lifting device.

[0041] In one possible implementation, the width of the first movable part is greater than the width of the first end. This larger width of the first movable part helps prevent stress concentration that could cause the first swing arm to break, thus extending its service life.

[0042] In one possible implementation, the lifting device further includes a third rocker arm and a second swing arm. The second swing arm includes a third end, a fourth end, and a second movable part located between the third end and the fourth end. The third end is slidably connected to the base, and the fourth end is rotatably connected to the mounting block. The third rocker arm includes a first end and a second end. The first end of the third rocker arm is rotatably connected to the base, and the second end of the third rocker arm is rotatably connected to the second movable part. During the switching between the first state and the second state of the lifting device, the direction of rotation of the second swing arm relative to the third rocker arm is opposite to the direction of rotation of the third rocker arm relative to the base.

[0043] It is understandable that in this embodiment, by setting a third rocker arm and a second swing arm to cooperate with the first rocker arm and the first swing arm, the mounting block can move relative to the base along the first or second direction, which is beneficial to improving the motion stability of the mounting block. Secondly, the second swing arm and the third rocker arm rotate in opposite directions, and the second swing arm and the third rocker arm can form a V-shaped structure, so that the displacement perpendicular to the first direction generated by the fourth end of the second swing arm relative to the third rocker arm when it moves can cancel out the displacement perpendicular to the first direction generated by the second end of the third rocker arm relative to the base when it moves.

[0044] In one possible implementation, the length between the third end and the second movable part is equal to the length of the third rocker arm. By setting the length between the third end and the second movable part to be equal to the length of the third rocker arm, when the lifting device switches between the first and second states, the third end of the second swing arm can slide relative to the base in a straight line. The movement of the third end of the second swing arm is simple and easy to control, and the thickness of the base can also be reduced, which is beneficial for achieving a thinner lifting device.

[0045] In one possible implementation, during the switching between the first and second states of the lifting device, the first and second swing arms rotate in opposite directions. Thus, when the lifting device is in the second state, the opening direction of the angle between the first swing arm and the plane of the base can be opposite to the opening direction of the angle between the second swing arm and the plane of the base. The first and second swing arms can roughly form a triangular structure with the mounting block, providing good support for the mounting block.

[0046] In one possible implementation, the length of the third rocker arm is equal to the length of the first rocker arm.

[0077] The embodiments of this application are described below with reference to the accompanying drawings.

[0078] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. 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. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" refers to at least two.

[0079] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0080] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0081] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in another embodiment" appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0082] The limitations mentioned in the embodiments of this application, such as parallel, perpendicular, identical, and equal (e.g., identical length, identical width, etc.), are all relative to the current technological level, and not absolute and strict mathematical definitions. A predetermined threshold deviation can exist between A and B with the same length. A predetermined angle deviation can exist between A and B that are parallel or perpendicular to each other. For example, the predetermined threshold can be a value within 10% of the dimension; for example, if the dimension is 10mm, the predetermined threshold can be 1mm or 0.5mm. The predetermined angle can be an angle within ±10°, for example, a predetermined angle deviation of ±5°.

[0083] It is understood that the specific embodiments described herein are merely for explaining the relevant invention and not for limiting the invention. It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0084] Figure 1 This is a schematic diagram of the structure of the electronic device 1000 provided in some embodiments of this application. Figure 2 yes Figure 1 The diagram shows the structure of the electronic device 1000 from another perspective. Figure 3 yes Figure 1 The diagram shows an exploded view of the electronic device 1000 in some embodiments.

[0085] like Figures 1 to 3 As shown, the electronic device 1000 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, wearable device, or other device with camera function. Figure 1 The electronic device 1000 shown is illustrated using a mobile phone as an example. It should be noted that... Figures 1 to 3The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 And the accompanying figures below. For ease of description, the width direction of electronic device 1000 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. It is understood that the coordinate system of electronic device 1000 can be flexibly set according to specific actual needs.

[0086] For example, electronic device 1000 may include a screen 100 and a housing 200. The screen 100 may be mounted on the housing 200. The screen 100 may be used to display images, text, etc. The housing 200 may include a mid-frame 201 and a back cover 202. The back cover 202 may be located on the side of the mid-frame 201 facing away from the screen 100 and is fixedly connected to the mid-frame 201. In this case, the back cover 202 and the mid-frame 201 may enclose the internal space of electronic device 1000. The internal space of electronic device 1000 may be used to house internal components of electronic device 1000, such as batteries, speakers, microphones, and earpieces.

[0087] For example, the electronic device 1000 may further include a camera decoration assembly 300 and a camera module 400. The back cover 202 may have a light-transmitting hole 203. The camera module 400 may be mounted on the side of the mid-frame 201 facing away from the screen 100. The light-entry hole of the camera module 400 may be exposed relative to the light-transmitting hole 203 of the back cover 202. The lens of the camera module 400 may extend or retract relative to the light-transmitting hole 203. The camera decoration assembly 300 may be fixed to the back cover 202. The projection of the camera decoration assembly 300 onto the plane of the back cover 202 may cover the light-transmitting hole 203. The camera decoration assembly 300 may include a lifting device 310 and a camera decoration element 320. The camera decoration element 320 may be mounted on the lifting device 310. The lifting device 310 may be used to drive the camera decoration element 320 to move along a first direction or a second direction. The first direction and the second direction may be opposite directions. The first direction may intersect with the thickness direction of the camera decoration element 320. In this embodiment, both the first and second directions can be parallel to the thickness direction of the camera decorative component 320. The first and second directions can also be parallel to the Z-axis direction. Specifically, the first direction can be the negative direction of the Z-axis, and the second direction can be the positive direction of the Z-axis. It should be noted that the parallelism and perpendicularity mentioned herein are not absolutely strict in a mathematical sense.

[0088] In other embodiments, when the electronic device 1000 is a device of other types, the electronic device 1000 may not include the screen 100.

[0089] Figure 4 yes Figure 3 The diagram shown is a structural schematic of the lifting device 310 in some embodiments when it is in the first state. Figure 5 yes Figure 4 The diagram shows the structure of the lifting device 310 in the second state. Figure 6 yes Figure 4 The diagram shows an exploded view of the lifting device 310 in some embodiments.

[0090] like Figures 4 to 6 As shown, the lifting device 310 may include a transmission mechanism 10, a drive mechanism 20, a base 30, and a mounting block 40. Both the transmission mechanism 10 and the drive mechanism 20 can be mounted on the base 30. The mounting block 40 can be mounted on the transmission mechanism 10. The mounting block 40 can be used to mount the camera decorative piece 320. The drive mechanism 20 can be electrically connected to the motherboard (not shown) of the electronic device 1000. The drive mechanism 20 can drive the transmission mechanism 10 to move the mounting block 40 and the camera decorative piece 320 together along a first direction or a second direction, thereby achieving the lifting and lowering of the camera decorative piece 320 relative to the base 30.

[0091] For example, the lifting device 310 may have a first state and a second state. When the lifting device 310 is in the first state (e.g. Figure 4 As shown), the distance between the mounting block 40 and the base 30 can be a first distance. When the lifting device 310 is in the second state (e.g. Figure 5 As shown), the distance between the mounting block 40 and the base 30 can be a second distance. The second distance can be greater than the first distance. The camera decorative piece 320 can be lowered to a first state relative to the back cover 202 or raised to a second state relative to the back cover 202 under the action of the lifting device 310 (please refer to...). Figure 3 (As shown).

[0092] The specific structure of the lifting device 310 will be described below with reference to the accompanying drawings.

[0093] Figure 7 yes Figure 6 The diagram shows the structure of the base 30 of the lifting device 310 in some embodiments. Figure 8 yes Figure 7 The diagram shows the structure of the base 30 from another perspective. Figure 9 yes Figure 6 The diagram shows the assembly structure of the base 30 and drive mechanism 20 in some embodiments.

[0094] like Figures 7 to 9As shown, the base 30 may include a first side 31, a second side 32, a third side 33, and a fourth side 34 connected end to end. The first side 31 may be opposite to and spaced apart from the third side 33. The second side 32 may be opposite to and spaced apart from the fourth side 34. In this case, the first side 31, the second side 32, the third side 33, and the fourth side 34 of the base 30 can together enclose the inner space 35 of the base 30. The inner space 35 of the base 30 can be used to accommodate / avoid camera modules (please refer to...). Figure 3 (As shown).

[0095] For example, the first side portion 31 may have a mounting groove 311. The drive mechanism 20 may be disposed within the mounting groove 311 and fixedly connected to the base 30. The drive mechanism 20 may be a motor. The drive mechanism 20 may include a connected motor body 21 and an output shaft 22. The motor body 21 may be fixedly connected to the base 30 by means of screwing, welding, or other methods. The output shaft 22 may be spaced apart from the groove wall of the mounting groove 311.

[0096] Exemplarily, the second side portion 32 may have a first groove 321 and a second groove 322 spaced apart. The openings of both the first groove 321 and the second groove 322 may be formed on the surface of the second side portion 32 facing the inner space 35. The first groove 321 may be positioned closer to the first side portion 31 than the second groove 322. Exemplarily, the shape and size of the first groove 321 may be identical to those of the second groove 322. The first groove 321 may be generally elongated. The length extension direction of the first groove 321 may be parallel to the X-axis direction. In other embodiments, the first groove 321 may also have other shapes.

[0097] Exemplarily, the fourth side portion 34 may have a third groove 341 and a fourth groove 342 spaced apart. The openings of both the third groove 341 and the fourth groove 342 may be formed on the surface of the fourth side portion 34 facing the inner space 35. The third groove 341 may be positioned closer to the first side portion 31 than the fourth groove 342. The third groove 341 may be opposite to and spaced apart from the first groove 321. The shape and size of the third groove 341 may be identical to those of the first groove 321. The fourth groove 342 may be opposite to and spaced apart from the second groove 322. The shape and size of the fourth groove 342 may be identical to those of the second groove 322.

[0098] Figure 10 yes Figure 6 The diagram shows an exploded view of the transmission mechanism 10 in some embodiments. Figure 11 yes Figure 6 A partial structural schematic diagram of the lifting device 310 shown. Figure 12 yes Figure 4 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along point AA.

[0099] like Figures 10 to 12 As shown, the transmission mechanism 10 may include a first transmission assembly 11, a second transmission assembly 12, a third transmission assembly 13, a fourth transmission assembly 14, and a plurality of retaining rings 15. Exemplarily, the first transmission assembly 11 and the third transmission assembly 13 may be symmetrical structures. The second transmission assembly 12 and the fourth transmission assembly 14 may also be symmetrical structures. It should be noted that... Figure 6 The structure of the first transmission assembly 11, the second transmission assembly 12, the third transmission assembly 13, the fourth transmission assembly 14, and multiple retaining rings 15 are also illustrated.

[0100] Exemplarily, the first transmission assembly 11 may include a first rocker arm 111, a first connecting rod 112, a first swing arm 113, and a second rocker arm 114. The first rocker arm 111 may include a first end 111a and a second end 111b. The first rocker arm 111 may be located on the side of the motor body 21 of the drive mechanism 20 near the second side 32 of the base 30. The first end 111a of the first rocker arm 111 may have a first hole 1111. The first hole 1111 may be fitted onto the output shaft 22 of the drive mechanism 20. A retaining ring 15 may be fitted onto the end of the output shaft 22 that is exposed relative to the first end 111a of the first rocker arm 111. In this way, the retaining ring 15 can prevent the first rocker arm 111 from sliding relative to the output shaft 22 in its axial direction.

[0101] In this embodiment, the first hole 1111 and the output shaft 22 can be fitted together via a flat engagement, allowing the first end 111a of the first rocker arm 111 to rotate synchronously with the output shaft 22. When the drive mechanism 20 receives an electrical signal, the output shaft 22 can rotate relative to the base 30 in a first rotation direction a or a second rotation direction b, thereby causing the first rocker arm 111 to rotate relative to the base 30 in the same direction. The first rotation direction a can be opposite to the second rotation direction b. That is, the first end 111a of the first rocker arm 111 can be indirectly rotatably connected to the base 30 via the drive mechanism 20. In other embodiments, the first end 111a of the first rocker arm 111 can also be rotatably connected to the base 30 via a shaft hole engagement or other means, and connected to the output shaft 22.

[0102] Figure 13 yes Figure 4 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along BB.

[0103] like Figure 11 and Figure 13As shown, the first connecting rod 112 may include a first connecting end 112a and a second connecting end 112b. The first connecting end 112a of the first connecting rod 112 is rotatably connected to the second end 111b of the first rocker arm 111. The second rocker arm 114 may include a first end 114a and a second end 114b. The first end 114a of the second rocker arm 114 is rotatably connected to the second side 32 of the base 30. The first end 114a of the second rocker arm 114 may be located on the side of the first groove 321 of the second side 32 near the second groove 322. The second end 114b of the second rocker arm 114 is rotatably connected to the second connecting end 112b of the first connecting rod 112.

[0104] For example, the first swing arm 113 may include a first end 113a and a second end 113b. The first end 113a of the first swing arm 113 may be slidably connected to the second side 32 of the base 30. The first end 113a of the first swing arm 113 may be provided with a sliding protrusion that engages with a first groove 321 of the second side 32, so that the first end 113a of the first swing arm 113 may be slidably connected to the first groove 321 of the second side 32.

[0105] Exemplarily, the first swing arm 113 may further include a first movable portion 113c. The first movable portion 113c may be located between the first end 113a and the second end 113b of the first swing arm 113. The first movable portion 113c may be spaced apart from the first end 113a and the second end 113b. The first movable portion 113c of the first swing arm 113 may be rotatably connected to the first connecting rod 112. For example, the first movable portion 113c may be rotatably connected to the second end 113b of the first connecting rod 112. In other embodiments, the first movable portion 113c may also be rotatably connected to the second rocker arm 114 and spaced apart from the first end 114a of the second rocker arm 114, that is, spaced apart from the base 30. Alternatively, the first movable portion 113c may also be rotatably connected to the first rocker arm 111 and spaced apart from the first end 111a of the first rocker arm 111, that is, spaced apart from the base 30.

[0106] For example, the length between the first end 113a and the first movable part 113c of the first swing arm 113 can be a first length. The distance between the second end 113b and the first movable part 113c can be a second length. The first length can be equal to the second length. The first length can also be equal to the length of the second rocker arm 114.

[0107] For example, the width of the first movable portion 113c of the first swing arm 113 can be greater than the width of the first end portion 113a. In this way, the width of the first movable portion 113c is larger, which can avoid stress concentration that could cause the first swing arm 113 to break, and thus help extend the service life of the first swing arm 113.

[0108] Figure 14 yes Figure 4 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along CC. Figure 15 yes Figure 4 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along DD.

[0109] like Figure 12 , Figure 14 as well as Figure 15 As shown, the third transmission assembly 13 may include a fourth rocker arm 131, a second connecting rod 132, a third swing arm 133, and a fifth rocker arm 134. It should be noted that... Figure 10 The structure of the fourth rocker arm 131, the second connecting rod 132, the third swing arm 133, and the fifth rocker arm 134 is also illustrated. The fourth rocker arm 131 may include a first end 131a and a second end 131b. The fourth rocker arm 131 may be located on the fourth side 34 of the motor body 21 of the drive mechanism 20 near the base 30, that is, the fourth rocker arm 131 and the first rocker arm 111 may be located on opposite sides of the motor body 21. The first end 131a of the fourth rocker arm 131 may have a second hole 1311. The second hole 1311 can be fitted onto the output shaft 22 of the drive mechanism 20. A retaining ring 15 can be fitted onto the end of the output shaft 22 opposite to the exposed end 131a of the fourth rocker arm 131. In this way, the retaining ring 15 can prevent the fourth rocker arm 131 from sliding relative to the output shaft 22 along its axial direction.

[0110] In this embodiment, the second hole 1311 and the output shaft 22 can be fitted together via a flat engagement, allowing the first end 131a of the fourth rocker arm 131 to rotate synchronously with the output shaft 22. When the drive mechanism 20 inputs an electrical signal, the output shaft 22 can rotate relative to the base 30 in a first rotation direction a or a second rotation direction b, thereby driving the fourth rocker arm 131 to rotate together relative to the base 30 in the same direction. That is, the first end 131a of the fourth rocker arm 131 can be indirectly rotatably connected to the base 30 via the drive mechanism 20. In other embodiments, the first end 131a of the fourth rocker arm 131 can also be rotatably connected to the base 30 via a shaft hole engagement or other means, and connected to the output shaft 22.

[0111] Exemplarily, the second link 132 may include a third connecting end 132a and a fourth connecting end 132b. The third connecting end 132a of the second link 132 is rotatably connected to the second end 131b of the fourth rocker arm 131. The fifth rocker arm 134 may include a first end 134a and a second end 134b. The first end 134a of the fifth rocker arm 134 is rotatably connected to the fourth side 34 of the base 30. The first end 134a of the fifth rocker arm 134 may be located on the side of the third groove 341 of the fourth side 34 near the fourth groove 342. The second end 134b of the fifth rocker arm 134 is rotatably connected to the fourth connecting end 132b of the second link 132.

[0112] For example, the third swing arm 133 may include a fifth end 133a and a sixth end 133b. The fifth end 133a of the third swing arm 133 may be slidably connected to the fourth side 34 of the base 30. The fifth end 133a of the third swing arm 133 may be provided with a sliding protrusion that engages with the third groove 341 of the fourth side 34, so that the fifth end 133a of the third swing arm 133 may be slidably connected to the third groove 341 of the fourth side 34.

[0113] Exemplarily, the third swing arm 133 may further include a third movable portion 133c. A second movable portion may be located between the fifth end 133a and the sixth end 133b of the third swing arm 133. The third movable portion 133c may be spaced apart from the fifth end 133a and the sixth end 133b. The third movable portion 133c of the third swing arm 133 may be rotatably connected to the second connecting rod 132. For example, the third movable portion 133c may be rotatably connected to the fourth connecting end 132b of the second connecting rod 132. In other embodiments, the third movable portion 133c may also be rotatably connected to the fifth rocker arm 134 and spaced apart from the first end 134a of the fifth rocker arm 134, that is, spaced apart from the base 30. Alternatively, the third movable portion 133c may also be rotatably connected to the fourth rocker arm 131 and spaced apart from the first end 131a of the fourth rocker arm 131, that is, spaced apart from the base 30.

[0114] Please refer to it again. Figure 14 The transmission mechanism 10 may further include a connecting rod 16. The connecting rod 16 may be fixedly connected between the first rocker arm 111 and the fourth rocker arm 131. In this way, the first rocker arm 111 and the fourth rocker arm 131 can move synchronously. Exemplarily, the second end 111b of the first rocker arm 111 and one end of the connecting rod 16 may be engaged through a shaft hole, so that the second end 111b of the first rocker arm 111 is fixedly connected to the connecting rod 16. The second end 131b of the fourth rocker arm 131 and the other end of the connecting rod 16 may also be engaged through a shaft hole, so that the second end 131b of the fourth rocker arm 131 is fixedly connected to the connecting rod 16. In other embodiments, the connecting rod 16 may also be integrally formed with the first rocker arm 111 and the fourth rocker arm 131.

[0115] Please refer to it again. Figure 11 , Figure 13 as well as Figure 15 When the lifting device 310 is in the first state, the angle between the first rocker arm 111 and the first plane can be the first included angle. The first plane can be perpendicular to the thickness direction of the electronic device 1000. In this embodiment, the first plane can be perpendicular to the Z-axis direction. The angle between the second rocker arm 114 and the first plane can be equal to the angle between the first rocker arm 111 and the first plane, which is also the first included angle. The angles between the fourth rocker arm 131 and the fifth rocker arm 134 and the first plane can also be the same as the angle between the first rocker arm 111 and the first plane (including the same angle and the same opening direction), which is also the first included angle.

[0116] The angle between the first swing arm 113 and the first plane can be the second angle. The angle between the third swing arm 133 and the first plane can be the same as the angle between the first swing arm 113 and the first plane, which is also the second angle. The opening direction of the second angle can be opposite to the opening direction of the first angle. For example, the first angle can be equal to the second angle.

[0117] The distance between the second end 113b of the first swing arm 113 and the base 30 can be a first spacing. The distance between the sixth end 133b of the third swing arm 133 and the base 30 can be equal to the first spacing.

[0118] Figure 16 yes Figure 11 The diagram shown is a schematic of the structure in its second state. Figure 17 yes Figure 13 The diagram shown is a schematic of the structure in its second state. Figure 18 yes Figure 15 The diagram shown is a schematic of the structure in its second state.

[0119] like Figures 16 to 18 As shown, when the lifting device 310 is in the second state, the angle between the first rocker arm 111 and the first plane can be the third angle. The angle between the second rocker arm 114 and the first plane can be equal to the angle between the first rocker arm 111 and the first plane, which is also the third angle. The angles between the fourth rocker arm 131 and the fifth rocker arm 134 and the first plane can also be the same as the angle between the first rocker arm 111 and the first plane, which is also the third angle.

[0120] The angle between the first swing arm 113 and the first plane can be a fourth included angle. The angle between the third swing arm 133 and the first plane can be the same as the angle between the first swing arm 113 and the first plane, which is also the fourth included angle. The opening direction of the third included angle can be opposite to the opening direction of the fourth included angle. The third included angle can be greater than the first included angle. The fourth included angle can be greater than the second included angle. For example, the third included angle can be equal to the fourth included angle. Both the third and fourth included angles can be less than 90°.

[0121] The distance between the second end 113b of the first swing arm 113 and the base 30 can be a second spacing. The distance between the sixth end 133b of the third swing arm 133 and the base 30 can be equal to the second spacing. The second spacing can be greater than the first spacing.

[0122] Please combine Figure 11 , Figures 15 to 18 As shown, during the transition from the first state to the second state of the lifting device 310, the drive mechanism 20 can input a first electrical signal, and the output shaft 22 can rotate along the first rotation direction a, driving the first rocker arm 111 and the fourth rocker arm 131 to rotate together relative to the base 30 along the first rotation direction a. At this time, the second rocker arm 114 and the fifth rocker arm 134 can both rotate in the same direction as the first rocker arm 111. The first connecting rod 112 can move relative to the base 30 under the action of the first rocker arm 111 and the second rocker arm 114. The first connecting rod 112 can generate displacement relative to the base 30 along the first direction and the third direction. The second connecting end 112b of the first connecting rod 112 can rotate relative to the base 30, and the direction of rotation can be the same as the direction of rotation of the first rocker arm 111 relative to the base 30. The radius of rotation of the second connecting end 112b relative to the base 30 can be equal to the length of the second rocker arm 114. The third direction can intersect with the first direction. At this time, the first rocker arm 111, the second rocker arm 114, the first connecting rod 112, and the base 30 can together form a four-bar linkage, such as a first connecting rod mechanism. For example, the displacement of the first connecting rod 112 relative to the base 30 in a third direction can be a first displacement.

[0123] In this embodiment, the first swing arm 113 can rotate relative to the first connecting rod 112 about the first movable part 113c as the rotation center, along the second rotation direction b, under the action of the first linkage mechanism. The first end 113a of the first swing arm 113 can slide relative to the first slide groove 321 in a direction close to the second rocker arm 114. The second end 113b of the first swing arm 113 can generate displacements relative to the first connecting rod 112 along the first direction and the fourth direction. The fourth direction can intersect the first direction and be opposite to the third direction. For example, the displacement of the second end 111b of the first swing arm 113 relative to the first connecting rod 112 along the fourth direction can be the second displacement. In this embodiment, the third direction can be parallel to the X-axis direction. That is, the fourth direction can be parallel to the X-axis direction, and both the third and fourth directions can be perpendicular to the first direction. The third direction can be the positive direction of the X-axis. The fourth direction can be the negative direction of the X-axis.

[0124] The second link 132 can move relative to the base 30 under the action of the fourth rocker 131 and the fifth rocker 134. The second link 132 can generate displacement relative to the base 30 along a first direction and a third direction. The displacement generated by the second link 132 relative to the base 30 can be the same as the displacement generated by the first link 112 relative to the base 30 (including the same direction and the same distance). At this time, the fourth rocker 131, the fifth rocker 134, the second link 132, and the base 30 can together constitute a four-bar linkage, such as the second linkage mechanism. The first linkage mechanism can operate synchronously with the second linkage mechanism.

[0125] The third swing arm 133, under the action of the second linkage mechanism, can rotate relative to the second link 132 with the third movable part 133c as the rotation center, along the second rotation direction b. The fifth end 133a of the third swing arm 133 can slide relative to the third slide groove 341 in a direction close to the fifth rocker arm 134. The sixth end 133b of the third swing arm 133 can generate displacement relative to the second link 132 along the first and fourth directions. The displacement generated by the sixth end 133b of the third swing arm 133 relative to the second link 132 can be the same as the displacement generated by the first end 113a of the first swing arm 113 relative to the first link 112.

[0126] For example, during the transition of the lifting device 310 from the second state to the first state, the drive mechanism 20 can input a second electrical signal, and the output shaft 22 can rotate along the second rotation direction b, driving the first rocker arm 111 and the fourth rocker arm 131 to rotate together relative to the base 30 along the second rotation direction b. At this time, the second rocker arm 114 and the fifth rocker arm 134 can both rotate in the same direction as the first rocker arm 111. The first connecting rod 112 can move relative to the base 30 under the action of the first rocker arm 111 and the second rocker arm 114. The first connecting rod 112 can generate displacement relative to the base 30 along the second and fourth directions. The first swing arm 113 can rotate relative to the first connecting rod 112 with the first movable part 113c as the rotation center, along the first rotation direction a, under the action of the first connecting rod mechanism. The first end 113a of the first swing arm 113 can slide relative to the first slide groove 321 in a direction away from the second rocker arm 114. The second end 113b of the first swing arm 113 can generate displacement relative to the first link 112 in the second and third directions.

[0127] The second link 132 can be displaced relative to the base 30 in both the second and fourth directions. The displacement of the second link 132 relative to the base 30 can be the same as the displacement of the first link 112 relative to the base 30 (including the same direction and the same distance of movement). The third swing arm 133, under the action of the second link mechanism, can rotate relative to the second link 132 about the third movable part 133c as its rotation center, along the first rotation direction a. The fifth end 133a of the third swing arm 133 can slide relative to the third slide groove 341 in a direction away from the fifth rocker arm 134. The sixth end 133b of the third swing arm 133 can be displaced relative to the second link 132 in both the second and third directions. The displacement of the sixth end 133b of the third swing arm 133 relative to the second link 132 can be the same as the displacement of the first end 113a of the first swing arm 113 relative to the first link 112.

[0128] Please combine again Figure 11 , Figures 15 to 18 As shown, the length of the first rocker arm 111 can be equal to the length of the second rocker arm 114. The length of the fourth rocker arm 131 can be equal to the length of the fifth rocker arm 134. In this case, both the first and second linkage mechanisms can be parallelogram mechanisms. Thus, when the lifting device 310 switches between the first and second states, both the first linkage 112 and the second linkage 132 can only translate relative to the base 30 without rotating relative to it. This makes the movement of the first linkage 112 and the second linkage 132 relatively simple and easy to control.

[0129] For example, the length of the second rocker arm 114 can be equal to the length of the first rocker arm 113, that is, the length of the second rocker arm 114 can be equal to the length from the first end 113a to the first movable part 113c of the first swing arm 113. In this case, the second rocker arm 114, the portion of the first swing arm 113 located between the first movable part 113c and the first end 113a, and the base 30 can approximately form an isosceles triangle structure. When the lifting device 310 switches between the first state and the second state, the second rocker arm 114 and the first swing arm 113 can rotate relative to the base 30 in opposite directions with equal rotation angles. The first end 113a of the first swing arm 113 can slide relative to the base 30 in a straight line direction (i.e., the X-axis direction in this embodiment). In this way, by setting the lengths of the second rocker arm 114 and the first end 113a of the first swing arm 113 to the first movable part 113c to be equal, the first end 113a of the first swing arm 113 can slide relative to the base 30 in a straight line direction, and the first slide groove 321 can be roughly elongated, thereby effectively reducing the thickness of the base 30, which is beneficial to reducing the overall thickness of the lifting device 310 and achieving a thinner design.

[0130] In other embodiments, the first transmission assembly 11 may not include the second rocker arm 114. The second connecting end 112b of the first connecting rod 112 may also be movably connected to the base 30. The base 30 may also have an arc-shaped groove (not shown). The second connecting end 112b of the first connecting rod 112 may be slidably connected to the arc-shaped groove. The center of curvature of the arc-shaped groove may be located on the side of the arc-shaped groove away from the first rocker arm 111. The radius of the arc-shaped groove is also the radius of rotation relative to the base 30 for the second connecting end 112b of the first connecting rod 112 to rotate.

[0131] In other embodiments, the first transmission assembly 11 may also exclude the first connecting rod 112 and the second rocker arm 114. The first movable part 113c of the first swing arm 113 is rotatably connected to the first rocker arm 111 and is spaced apart from the first end 111a of the first rocker arm 111, that is, spaced apart from the base 30.

[0132] Figure 19 yes Figure 6 A partial structural schematic diagram of the lifting device 310 shown. Figure 20 yes Figure 4 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along BB. Figure 21 yes Figure 4 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along DD.

[0133] like Figures 19 to 21As shown, the second transmission assembly 12 may include a third rocker arm 121 and a second swing arm 122. The fourth transmission assembly 14 may include a sixth rocker arm 141 and a fourth swing arm 142. It should be noted that... Figure 10 The structure of the third rocker arm 121, the second swing arm 122, the sixth rocker arm 141, and the fourth swing arm 142 is also illustrated. The third rocker arm 121 may include a first end 121a and a second end 121b. The first end 121a of the third rocker arm 121 is rotatably connected to the second side 32 of the base 30 and is spaced apart from the first linkage mechanism. The second swing arm 122 may include a third end 122a and a fourth end 122b. The third end 122a of the second swing arm 122 is slidably connected to the second side 32 of the base 30. The third end 122a of the second swing arm 122 may have a sliding protrusion that engages with the second groove 322 of the second side 32, allowing the third end 122a of the second swing arm 122 to slidably connect to the second groove 322 of the second side 32.

[0134] Exemplarily, the second swing arm 122 may further include a second movable portion 122c. The second movable portion 122c may be located between the third end 122a and the fourth end 122b of the second swing arm 122. The second movable portion 122c may be spaced apart from the third end 122a and the fourth end 122b. The second movable portion 122c of the second swing arm 122 may be rotatably connected to the second end 121b of the third rocker arm 121. In other embodiments, the second movable portion 122c of the second swing arm 122 may also be rotatably connected to other positions of the third rocker arm 121 and spaced apart from the first end 121a of the third rocker arm 121, that is, spaced apart from the base 30.

[0135] For example, the length between the third end 122a and the second movable part 122c of the second swing arm 122 can be a third length. The distance between the second end 114b and the second movable part 122c can be a fourth length. The first length can be equal to the fourth length.

[0136] For example, the width of the second movable portion 122c of the second swing arm 122 can be greater than the width of the third end portion 122a. In this way, the larger width of the second movable portion 122c can avoid stress concentration that could cause the second swing arm 122 to break, thus extending the service life of the second swing arm 122.

[0137] For example, the sixth rocker arm 141 may include a first end 141a and a second end 141b. The first end 141a of the sixth rocker arm 141 is rotatably connected to the fourth side 34 of the base 30 and is spaced apart from the second linkage mechanism. The fourth rocker arm 142 may include a seventh end 142a and an eighth end 142b. The seventh end 142a of the fourth rocker arm 142 is slidably connected to the fourth side 34 of the base 30. The seventh end 142a of the fourth rocker arm 142 may be provided with a sliding protrusion that engages with the fourth groove 342 of the fourth side 34, so that the seventh end 142a of the fourth rocker arm 142 can slidably connect to the fourth groove 342 of the fourth side 34.

[0138] Exemplarily, the fourth swing arm 142 may further include a fourth movable portion 142c. The fourth movable portion 142c may be located between the seventh end 142a and the eighth end 142b of the fourth swing arm 142. The fourth movable portion 142c may be spaced apart from the seventh end 142a and the eighth end 142b. The fourth movable portion 142c of the fourth swing arm 142 may be rotatably connected to the second end 141b of the sixth rocker arm 141. In other embodiments, the fourth movable portion 142c of the fourth swing arm 142 may also be rotatably connected to other positions of the sixth rocker arm 141 and spaced apart from the first end 141a of the sixth rocker arm 141, that is, spaced apart from the base 30.

[0139] Please refer to it again. Figures 19 to 21 When the lifting device 310 is in the first state, the angle between the third rocker arm 121 and the first plane can be the fifth angle. The angle between the sixth rocker arm 141 and the first plane can be the same as the angle between the third rocker arm 121 and the first plane, which is also the fifth angle. The angle between the second swing arm 122 and the first plane can be the sixth angle. The angle between the fourth swing arm 142 and the first plane can be the same as the angle between the second swing arm 122 and the first plane, which is also the sixth angle. The opening direction of the fifth angle can be opposite to the opening direction of the sixth angle.

[0140] The fifth included angle can be equal to the sixth included angle. The fifth included angle can be equal to the first included angle (in this embodiment, the angle between the first rocker arm 111 and the first plane when the lifting device 310 is in the first state), but with the opposite opening direction. The sixth included angle can be equal to the second included angle (in this embodiment, the angle between the first swing arm 113 and the first plane when the lifting device 310 is in the first state), but with the opposite opening direction. In other embodiments, the opening direction of the fifth included angle can also be the same as the opening direction of the first included angle. The opening direction of the sixth included angle can also be the same as the opening direction of the second included angle.

[0141] The distance between the fourth end 122b of the second swing arm 122 and the base 30 can be equal to the distance between the second end 113b of the first swing arm 113 and the base 30, which is the first spacing. The distance between the eighth end 142b of the fourth swing arm 142 and the base 30 can also be equal to the first spacing.

[0142] Figure 22 yes Figure 19 The diagram shown is a schematic of the structure in its second state. Figure 23 yes Figure 20 The diagram shown is a schematic of the structure in its second state. Figure 24 yes Figure 21 The diagram shown is a schematic of the structure in its second state.

[0143] like Figures 22 to 24 As shown, when the lifting device 310 is in the second state, the angle between the third rocker arm 121 and the first plane can be the seventh angle. The angle between the sixth rocker arm 141 and the first plane can be the same as the angle between the third rocker arm 121 and the first plane, which is also the seventh angle. The angle between the second swing arm 122 and the first plane can be the eighth angle. The angle between the fourth swing arm 142 and the first plane can be the same as the angle between the second swing arm 122 and the first plane, which is also the eighth angle. The opening direction of the seventh angle can be opposite to the opening direction of the eighth angle.

[0144] The seventh included angle can be equal to the eighth included angle. The seventh included angle can also be equal to the third included angle (in this embodiment, the angle between the first rocker arm 111 and the first plane when the lifting device 310 is in the second state), but with the opposite opening direction. The eighth included angle can be the same as the fourth included angle (in this embodiment, the angle between the first swing arm 113 and the first plane when the lifting device 310 is in the second state), but with the opposite opening direction. In other embodiments, the opening direction of the seventh included angle can also be the same as the opening direction of the third included angle. The opening direction of the eighth included angle can also be the same as the opening direction of the fourth included angle.

[0145] The distance between the fourth end 122b of the second swing arm 122 and the base 30 can be equal to the distance between the second end 113b of the first swing arm 113 and the base 30, which is the second spacing. The distance between the eighth end 142b of the fourth swing arm 142 and the base 30 can also be equal to the second spacing.

[0146] Please combine Figures 19 to 24As shown, during the transition from the first state to the second state of the lifting device 310, the third rocker arm 121 can rotate relative to the base 30 along the second rotation direction b. The second end 131b of the third rocker arm 121 can generate displacements relative to the base 30 along the first and fourth directions. For example, the fourth displacement generated by the second end 131b of the third rocker arm 121 relative to the base 30 can be a third displacement.

[0147] The second swing arm 122 can rotate relative to the third rocker arm 121 about the second movable part 122c as the rotation center, along the first rotation direction a. The third end 122a of the second swing arm 122 can slide relative to the second slide groove 322 in a direction close to the third rocker arm 121. The fourth end 122b of the second swing arm 122 can generate displacements along the first and third directions relative to the second end 131b of the third rocker arm 121. For example, the displacement along the third direction generated by the fourth end 122b of the second swing arm 122 relative to the second end 131b of the third rocker arm 121 can be a fourth displacement.

[0148] The sixth rocker arm 141 can rotate relative to the base 30 along the second rotation direction b. The second end 141b of the sixth rocker arm 141 can generate displacement relative to the base 30 along the first and fourth directions. The displacement generated by the second end 141b of the sixth rocker arm 141 relative to the base 30 can be the same as the displacement generated by the second end 131b of the third rocker arm 121 relative to the base 30 (including the same direction and the same distance of movement).

[0149] The fourth swing arm 142, under the action of the sixth rocker arm 141, can rotate relative to the second end 141b of the sixth rocker arm 141, with the fourth movable part 142c as the rotation center, along the first rotation direction a. The seventh end 142a of the fourth swing arm 142 can slide relative to the fourth slide groove 342 in a direction close to the sixth rocker arm 141. The eighth end 142b of the fourth swing arm 142 can generate displacement relative to the second end 141b of the sixth rocker arm 141 along the first direction and the third direction. The displacement generated by the eighth end 142b of the fourth swing arm 142 relative to the second end 141b of the sixth rocker arm 141 can be the same as the displacement generated by the fourth end 122b of the second swing arm 122 relative to the second end 131b of the third rocker arm 121.

[0150] For example, during the transition of the lifting device 310 from the second state to the first state, the third rocker arm 121 can rotate relative to the base 30 along the first rotation direction a. The second end 131b of the third rocker arm 121 can generate displacement relative to the base 30 along the second direction and the third direction. For example, the third displacement generated by the second end 131b of the third rocker arm 121 relative to the base 30 in the third direction can be the fifth displacement.

[0151] The second swing arm 122 can rotate relative to the third rocker arm 121 about the second movable part 122c as the rotation center, along the second rotation direction b. The third end 122a of the second swing arm 122 can slide relative to the second slide groove 322 in a direction away from the third rocker arm 121. The fourth end 122b of the second swing arm 122 can generate displacements along the second and fourth directions relative to the second end 131b of the third rocker arm 121. For example, the displacement along the fourth direction generated by the fourth end 122b of the second swing arm 122 relative to the second end 131b of the third rocker arm 121 can be a sixth displacement.

[0152] The sixth rocker arm 141 can rotate relative to the base 30 along a first rotation direction a. The second end 141b of the sixth rocker arm 141 can generate displacement relative to the base 30 along a second direction and a third direction. The displacement generated by the second end 141b of the sixth rocker arm 141 relative to the base 30 can be the same as the displacement generated by the second end 131b of the third rocker arm 121 relative to the base 30 (including the same direction and the same distance of movement).

[0153] The fourth swing arm 142, under the action of the sixth rocker arm 141, can rotate relative to the second end 141b of the sixth rocker arm 141, with the fourth movable part 142c as the rotation center, along the second rotation direction b. The seventh end 142a of the fourth swing arm 142 can slide relative to the fourth slide groove 342 in a direction away from the sixth rocker arm 141. The eighth end 142b of the fourth swing arm 142 can generate displacements along the second and fourth directions relative to the second end 141b of the sixth rocker arm 141. The displacement generated by the eighth end 142b of the fourth swing arm 142 relative to the second end 141b of the sixth rocker arm 141 can be the same as the displacement generated by the fourth end 122b of the second swing arm 122 relative to the second end 131b of the third rocker arm 121.

[0154] Please combine again Figures 19 to 24As shown, the length of the third rocker arm 121 can be equal to the third length, that is, the length of the third rocker arm 121 can be equal to the length between the third end 122a of the second swing arm 122 and the second movable part 122c. At this time, the third rocker arm 121, the portion of the second swing arm 122 located between the second movable part 122c and the first end 114a, and the base 30 can approximately form an isosceles triangle structure. When the lifting device 310 switches between the first state and the second state, the third rocker arm 121 and the second swing arm 122 can rotate in opposite directions relative to the base 30, and the rotation angles are equal. The third end 122a of the second swing arm 122 can slide relative to the base 30 in a straight line direction (that is, in this embodiment, the X-axis direction). In this way, by setting the lengths of the third rocker arm 121 and the third end 122a of the second swing arm 122 to the second movable part 122c to be equal, the third end 122a of the second swing arm 122 can slide relative to the base 30 in a straight line, and the second slide groove 322 can be roughly elongated, thereby effectively reducing the thickness of the base 30, which is beneficial to reducing the overall thickness of the lifting device 310 and achieving a thinner design.

[0155] Figure 25 yes Figure 4 The diagram shows a cross-sectional view of one embodiment of the lifting device 310 cut along BB. Figure 26 yes Figure 4 The diagram shows a cross-sectional view of one embodiment of the lifting device 310 cut along DD. Figure 27 yes Figure 25 The diagram shows the structure of the lifting device 310 in the second state. Figure 28 yes Figure 26 The diagram shows the structure of the lifting device 310 in the second state.

[0156] Please see Figures 25 to 28 and combined Figure 4 and Figure 5 As shown, the mounting block 40 can be connected to the base 30 via the transmission mechanism 10. The second end 113b of the first swing arm 113, the fourth end 122b of the second swing arm 122, the sixth end 133b of the third swing arm 133, and the eighth end 142b of the fourth swing arm 142 of the transmission mechanism 10 can all be rotatably connected to the mounting block 40.

[0157] For example, during the transition from the first state to the second state of the lifting device 310, the drive mechanism 20 can drive the first rocker arm 111 of the first linkage mechanism and the fourth rocker arm 131 of the second linkage mechanism to rotate relative to the base 30 along the first rotation direction a, causing movement in both the first and second linkage mechanisms. The first swing arm 113, under the action of the first linkage mechanism, can rotate relative to the first linkage mechanism with its first movable part 113c as the center of rotation along the second rotation direction b. The third swing arm 133, under the action of the second linkage mechanism, can rotate relative to the second linkage mechanism with its third movable part 133c as the center of rotation along the second rotation direction b. At this time, both the third rocker arm 121 and the sixth rocker arm 141 can rotate relative to the base 30 along the second rotation direction b. The second swing arm 122 can rotate relative to the third rocker arm 121 with its second movable part 122c as the center of rotation along the first rotation direction a. The fourth swing arm 142 can rotate relative to the sixth rocker arm 141 with its fourth movable part 142c as the center of rotation along the first rotation direction a.

[0158] Specifically, the first displacement of the first link 112 relative to the base 30 along a third direction can be equal to the second displacement of the second end 113b of the first swing arm 113 relative to the first link 112 along a fourth direction. Thus, when the first link 112 displaces relative to the base 30 along a third direction, the second end 113b of the first swing arm 113, under the action of the first link 112, can also displace relative to the base 30 along a third direction together with the first link 112. Simultaneously, the second end 113b of the first swing arm 113 can also displace relative to the first link 112 along a fourth direction, and this second displacement can cancel out the first displacement. In other words, during the transition of the lifting device 310 from the first state to the second state, the second end 113b of the first swing arm 113 can move relative to the base 30 along a first direction. Similarly, the sixth end 133b of the third swing arm 133 can move relative to the base 30 along a first direction.

[0159] The third displacement in the fourth direction generated by the second end 131b of the third rocker arm 121 relative to the base 30 is equal to the fourth displacement in the third direction generated by the fourth end 122b of the second swing arm 122 relative to the second end 131b of the third rocker arm 121. Thus, when the second end 131b of the third rocker arm 121 displaces in the fourth direction relative to the base 30, the fourth end 122b of the second swing arm 122, under the action of the third rocker arm 121, can also generate a third displacement in the fourth direction relative to the base 30 along with the third rocker arm 121. Simultaneously, the fourth end 122b of the second swing arm 122 can also generate a fourth displacement in the third direction relative to the second end 131b of the third rocker arm 121, which can cancel out the third displacement. In other words, during the switching process of the lifting device 310 from the first state to the second state, the fourth end 122b of the second swing arm 122 can move in the first direction relative to the base 30. Similarly, the fourth swing arm 142 can move in the first direction relative to the base 30.

[0160] At this time, the second end 113b of the first swing arm 113, the fourth end 122b of the second swing arm 122, the sixth end 133b of the third swing arm 133, and the eighth end 142b of the fourth swing arm 142 can all move relative to the base 30 in the first direction, thereby enabling the mounting block 40 to move relative to the base 30 in the first direction and achieve linear ascent.

[0161] Please refer to it again. Figures 25 to 28 and combined Figure 4 and Figure 5 As shown, during the transition from the second state to the first state of the lifting device 310, the drive mechanism 20 can drive the first rocker arm 111 of the first linkage mechanism and the fourth rocker arm 131 of the second linkage mechanism to rotate relative to the base 30 along the second rotation direction b, causing movement in both the first and second linkage mechanisms. The first swing arm 113, under the action of the first linkage mechanism, can rotate relative to the first linkage mechanism with the first movable part 113c as its rotation center along the first rotation direction a. The third swing arm 133, under the action of the second linkage mechanism, can rotate relative to the second linkage mechanism with the third movable part 133c as its rotation center along the first rotation direction a. At this time, both the third rocker arm 121 and the sixth rocker arm 141 can rotate relative to the base 30 along the first rotation direction a. The second swing arm 122 can rotate relative to the third rocker arm 121 with the second movable part 122c as its rotation center along the second rotation direction b. The fourth swing arm 142 can rotate relative to the sixth rocker arm 141 with the fourth movable part 142c as its rotation center along the second rotation direction b.

[0162] The displacement of the first link 112 relative to the base 30 along the fourth direction is equal to the displacement of the second end 113b of the first swing arm 113 relative to the first link 112 along the fourth direction. Thus, during the transition of the lifting device 310 from the second state to the first state, the second end 113b of the first swing arm 113 can move relative to the base 30 along the second direction. Similarly, the sixth end 133b of the third swing arm 133 can move relative to the base 30 along the second direction.

[0163] The displacement of the second end 131b of the third rocker arm 121 relative to the base 30 along the fourth direction is equal to the displacement of the fourth end 122b of the second swing arm 122 relative to the second end 131b of the third rocker arm 121 along the third direction. Thus, during the transition of the lifting device 310 from the first state to the second state, the fourth end 122b of the second swing arm 122 can move relative to the base 30 along the second direction. Similarly, the fourth swing arm 142 can move relative to the base 30 along the second direction.

[0164] At this time, the second end 113b of the first swing arm 113, the fourth end 122b of the second swing arm 122, the sixth end 133b of the third swing arm 133, and the eighth end 142b of the fourth swing arm 142 can all move relative to the base 30 in the second direction, thereby enabling the mounting block 40 to move relative to the base 30 in the second direction and achieve a linear descent.

[0165] Understandably, compared to some lifting devices that use gears and worm gears to drive the camera decoration, which utilize the guide rail between the base and the mounting block to convert the circumferential rotation of the base into vertical lifting motion, this method results in a larger number of lifting devices, higher manufacturing costs, and a shorter lifting stroke for the camera decoration. Furthermore, the use of a higher-pair mechanism leads to lower transmission efficiency, higher frictional losses, and higher power consumption during operation. In contrast, the lifting device 310 in this embodiment connects the base 30 and the mounting block 40 via a transmission mechanism 10. This transmission mechanism 10 is a linkage mechanism, meaning the base 30 and the mounting block 40 are connected via a lower-pair mechanism, resulting in higher transmission efficiency, lower frictional losses, and reduced power consumption. The linkage mechanism 10 also increases the lifting stroke of the camera decoration. Additionally, the components of the transmission mechanism 10 have simple structures and are easy to manufacture, reducing manufacturing costs and simplifying the manufacturing process.

[0166] Secondly, in this embodiment, when the lifting device 310 is in the first state, the angle between each rocker arm of the transmission mechanism 10 and the first plane is small, thereby reducing the size of the lifting device 310 along the thickness direction of the electronic device 1000 in the first state. When the lifting device 310 is in the second state, the angle between each rocker arm of the transmission mechanism 10 and the first plane is large, thereby increasing the distance between the camera decoration and the base 30 after it is raised. When the lifting device 310 switches between the first and second states, the stroke for driving the camera decoration to rise and fall is large. In other words, the lifting device 310 in this embodiment can accommodate a long lifting stroke while meeting the requirements of a thin electronic device 1000.

[0167] In addition, in this embodiment, the first end 113a of the first swing arm 113 can be slidably connected to the base 30, and the second end 113b of the first swing arm 113 can be rotatably connected to the mounting block 40. The first swing arm 113 may also include a first movable part 113c located between the first end 113a and the second end 113b. The first movable part 113c can be rotatably connected to the first transmission mechanism 10 and is spaced apart from the base 30. In this way, when the lifting device 310 switches between the first state and the second state, the rotation direction of the first swing arm 113 is opposite to the rotation direction of the first rocker arm 111. The first swing arm 113 and part of the first transmission mechanism 10 can form a herringbone structure, so that the displacement perpendicular to the first direction generated by the second end 113b of the first swing arm 113 relative to the first rocker arm 111 when it moves can cancel out the displacement perpendicular to the first direction generated by the first transmission mechanism 10 relative to the base 30. In other words, the mounting block 40 can move relative to the base 30 in a first or second direction with the cooperation of the first swing arm 113 and the first transmission component 11, thereby realizing the lifting and lowering of the mounting block 40 relative to the base 30 in the thickness direction of the electronic device 1000, ensuring the stability and smoothness of the lifting and lowering movement of the camera decorative part.

[0168] During the transition from the first state to the second state of the lifting device 310, the first displacement can be equal to the second displacement. In this way, the first displacement can cancel out the second displacement, allowing the mounting block 40 to move the camera decorative piece linearly relative to the base 30 along its thickness direction, thus achieving linear lifting.

[0169] In addition, in this embodiment, the first movable part 113c of the first swing arm 113 can be rotatably connected to the first connecting rod 112. In this way, the first swing arm 113 can be spaced apart from the first rocker arm 111, and a clearance space can be formed between the first swing arm 113 and the first rocker arm 111 to avoid the mounting block 40. This can prevent the drive mechanism 20, the first rocker arm 111 and other structures from affecting the light intake of the camera module, which is beneficial to ensuring the amount of light intake of the camera module.

[0170] Furthermore, when the lifting device 310 in this embodiment is in the second state, the angle between the first swing arm 113 and the first plane can be less than 90°, thereby avoiding the transmission mechanism 10 from producing play and improving the motion accuracy of the lifting device 310. For example, the angle between the second swing arm 122 and the first plane can also be less than 90°.

[0171] Furthermore, in this embodiment, the rotation direction of the first swing arm 113 can be opposite to the rotation direction of the second swing arm 122. When the lifting device 310 is in the second state, the opening direction of the angle between the first swing arm 113 and the first plane can be opposite to the opening direction of the angle between the second swing arm 122 and the first plane, and the opening direction of the angle between the first swing arm 113 and the first plane can be opposite to the opening direction of the angle between the second swing arm 122 and the first plane, so that the first swing arm 113, the second swing arm 122 and the mounting block 40 can roughly form a triangular structure, and the first swing arm 113 and the second swing arm 122 can provide better support for the mounting block 40.

[0172] In some embodiments, the length of the third rocker arm 121 may also be equal to the length of the first rocker arm 111. Thus, when the lifting device 310 switches between the first and second states, the displacement of the second end 111b of the first rocker arm 111 relative to the base 30 in either the first or second direction can be the same as the displacement of the second end 121b of the third rocker arm 121 relative to the base in either the first or second direction, thereby helping to ensure the smoothness of the lifting of the mounting block 40 relative to the base 30.

[0173] In some embodiments, the length of the first swing arm 113 may also be equal to the length of the second swing arm 122. Thus, when the lifting device 310 switches between the first and second states, the displacement of the second end 113b of the first swing arm 113 relative to the base 30 along the first or second direction can be the same as the displacement of the fourth end 122b of the second swing arm 122 relative to the base 30 along the first or second direction, thereby helping to ensure the smoothness of the lifting of the mounting block 40 relative to the base 30.

[0174] In other embodiments, the second transmission component 12 may also take other mechanism forms.

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.
