Description

Technical Field

[0001] This application relates to the field of electronic devices, and in particular to a lifting device, a camera decorative component, and an electronic 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 lifting device, a camera decorative component, and an electronic 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 lifting device is provided. The lifting device is applied to a camera decorative component. The lifting device includes a base, a first transmission member, a first connecting rod, a driving member, and a mounting member. The driving member is connected to the first transmission member. The first transmission member 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 movably connected to the mounting member. The second end is rotatably connected to the base. The first connecting rod includes a first end, a second end, and a first mating movable portion located between the first end and the second end. The first end is rotatably connected to the mounting member. The second end is movably connected to the base. The first movable portion is rotatably connected to the first mating movable portion and has a sliding connection with the first mating movable portion. 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 member and the base is a first gap. When the lifting device is in the second state, the distance between the mounting member and the base is a second gap. The first gap is smaller than the second gap. When the lifting device switches between the first state and the second state, the distance between the mounting member and the base changes. The driving member drives the first transmission member to rotate relative to the base in a first rotation direction or in a second rotation direction.

[0005] Understandably, compared to conventional lifting devices that use gear and worm gear transmissions, utilizing the guide rail between the base and the mounting component to convert the circumferential rotation of the base into vertical lifting motion of the mounting component, this method results in a larger number of lifting devices, higher manufacturing costs, and a shorter lifting stroke for the mounting component. 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 the mounting component via a first transmission component and a first connecting rod, i.e., a linkage mechanism. In other words, the lifting device in this embodiment uses a lower-pair mechanism, resulting in higher transmission efficiency, lower frictional losses, and reduced power consumption. The linkage mechanism also increases the lifting stroke of the mounting component. Additionally, the simple structure and ease of manufacturing of the various components of the lifting device reduce manufacturing costs and lower manufacturing process difficulty.

[0006] Furthermore, compared to conventional lifting devices where the first link is only movably connected to the first transmission component, and the first transmission component drives the first link to move relative to the base, allowing the mounting component to rise or fall relative to the base, the first link's movement is difficult to control during operation, thus reducing the lifting device's motion accuracy. In this embodiment, the first end of the first link is rotatably connected to the mounting component, the first engaging part of the first link is movably connected to the first engaging part of the first transmission component, and the second end of the first link is also movably connected to the base. Thus, during operation, the first link can rotate relative to the base under the combined action of the mounting component, the first transmission component, and the base. This allows for more stable movement of the first link relative to the base, thereby improving the lifting device's motion accuracy.

[0007] In one possible implementation, during the transition from a first state to a second state of the lifting device, the first transmission member rotates relative to the base along a first rotational direction, the first connecting rod rotates relative to the mounting member along the first rotational direction, the second end slides relative to the base, and the mounting member moves relative to the base along a first direction. During the transition from a second state to a first state of the lifting device, the first transmission member rotates relative to the base along a second rotational direction, the first connecting rod rotates relative to the mounting member along a second rotational direction, the second end slides relative to the base, and the mounting member moves relative to the base along a second direction. The first and second directions are opposite. The first direction is parallel to the thickness direction of the base.

[0008] In this way, the mounting component can be displaced relative to the base in a first direction or a second direction under the action of the first transmission component and the first rod. That is, the mounting component can rise or fall relative to the base under the combined action of the first transmission component and the first rod, thereby realizing the lifting function of the lifting device.

[0009] In one possible implementation, one of the first movable part and the first mating movable part is a sliding protrusion, and the other is a groove. The groove is an arc-shaped groove, with the center of curvature of the groove located on the side of the groove facing the mounting part, or the groove is elongated, with the opening of the angle between the length extension direction of the groove and the thickness direction of the base facing the second direction.

[0010] In this way, the sliding protrusion of the first movable part and the sliding groove of the first mating movable part will slide within the groove, allowing the first transmission member to be movably connected to the first connecting rod. The first transmission member can drive the first connecting rod to move through the first and second movable parts. In other words, the first connecting rod can rotate relative to the mounting member in a first rotation direction or a second rotation direction under the action of the first transmission member.

[0011] In one possible implementation, during the switching process of the lifting device from a first state to a second state, the first movable part moves relative to the first mating movable part in a direction closer to the first end. During the switching process of the lifting device from a second state to a first state, the first movable part moves relative to the first mating movable part in a direction closer to the second end.

[0012] Thus, during the process of switching the lifting device from the first state to the second state, the first transmission component can drive the first connecting rod to rotate relative to the mounting component in the first rotation direction through the first movable part and the first mating movable part. During the process of switching the lifting device from the second state to the first state, the first transmission component can drive the first connecting rod to rotate relative to the mounting component in the second rotation direction through the first movable part and the first mating movable part.

[0013] In one possible implementation, when the lifting device is in a first state, the distance between the first end and the base is a first distance. The distance between the first end and the base is equal to the first distance. When the lifting device is in a second state, the distance between the first end and the base is a second distance. The second distance is greater than the first distance. The distance between the first end and the base is equal to the second distance.

[0014] It is understandable that the first end of the first transmission component and the first end of the first connecting rod are both connected to the mounting component. When the lifting device is in the first state and the second state, the distance between the first end of the first transmission component and the base is equal to the distance between the first end of the first connecting rod and the base. Thus, when the lifting device is in the first state and the second state, the distance between the connection point of the mounting component and the first transmission component and the base is equal to the distance between the connection point of the mounting component and the first connecting rod and the base. That is, the connection points of the mounting component with the first transmission component and the first connecting rod can move synchronously relative to the base, thereby preventing the mounting component from tilting during the operation of the lifting device and ensuring smooth lifting of the mounting component.

[0015] In one possible implementation, the first end has a first movable protrusion. The mounting member has a first movable groove. The length extension direction of the first movable groove is perpendicular to the thickness direction of the base. The first movable protrusion is rotatably connected to the first movable groove and has a sliding connection with the first movable groove. During the switching process between the first state and the second state of the lifting device, in the length extension direction of the first movable groove, the direction in which the first end moves relative to the base is opposite to the direction in which the mounting member moves relative to the first end.

[0016] It is understood that during the switching process between the first and second states of the lifting device, the direction in which the first end moves relative to the base along the length extension direction of the first movable slot is opposite to the direction in which the mounting member moves relative to the first end. In this way, the first movable protrusion of the first transmission member can cooperate with the first movable slot of the mounting member, allowing the mounting member to move relative to the base only along the first or second direction. That is, the mounting member in this embodiment can achieve linear lifting and lowering relative to the base. The mounting member only moves vertically relative to the base and not horizontally, thereby preventing the mounting member from bumping or squeezing the base or other components of the lifting device, and thus preventing damage to the lifting device.

[0017] In one possible implementation, the first connecting rod further includes a first sliding protrusion. The first sliding protrusion is located between the first end and the second end, and is spaced apart from the first mating movable part. The base has a first sliding groove. The first sliding groove is an arc-shaped groove. The center of curvature of the first sliding groove is located on the side of the first sliding groove facing the first end. The first sliding protrusion is rotatably connected to the first sliding groove, and there is a sliding connection between the first sliding protrusion and the first sliding groove. In this way, the first connecting rod can be movably connected to the base under the cooperation of the first sliding protrusion and the first sliding groove, thereby allowing the first connecting rod to move more stably relative to the base during the operation of the lifting device, thus improving the motion accuracy of the lifting device.

[0018] In one possible implementation, during the transition of the lifting device from a first state to a second state, the first sliding protrusion slides relative to the first slide groove in a direction closer to the mounting component. During the transition of the lifting device from the second state to the first state, the first sliding protrusion slides relative to the first slide groove in a direction farther from the mounting component. In this way, the first connecting rod can be movably connected to the base through the cooperation of the first sliding protrusion and the first slide groove, thereby allowing the first connecting rod to move more stably relative to the base during the operation of the lifting device, thus improving the motion accuracy of the lifting device.

[0019] In one possible implementation, the first connecting rod further has a second sliding protrusion. The second sliding protrusion is located at the second end and is spaced apart from the first mating movable part. The base also has a second sliding groove. The second sliding groove is elongated. The length of the second sliding groove extends perpendicular to the thickness direction of the base. The second sliding protrusion is rotatably connected to the second sliding groove and has a sliding connection with the second sliding groove. When the lifting device switches between the first state and the second state, the second sliding protrusion slides within the second sliding groove. In this way, the first connecting rod can be movably connected to the base under the cooperation of the second sliding protrusion and the second sliding groove, thereby enabling the first connecting rod to move more stably relative to the base during the operation of the lifting device, thus improving the motion accuracy of the lifting device.

[0020] In one possible implementation, the lifting device further includes a second connecting rod. The second connecting rod includes a third end and a fourth end. The third end is opposite to and spaced apart from the first end. The fourth end is opposite to and spaced apart from the second end. The third end is rotatably connected to a mounting member. When the lifting device switches from a first state to a second state, the second connecting rod rotates relative to the mounting member in a first rotation direction, and the fourth end slides relative to the base. When the lifting device switches from a second state to a first state, the second connecting rod rotates relative to the mounting member in a second rotation direction, and the fourth end slides relative to the base.

[0021] It is understood that the lifting device in this embodiment also includes a second connecting rod, the third end of which is rotatably connected to a mounting component. This improves the structural strength of the lifting device, allowing the mounting component to achieve more stable lifting relative to the base under the combined action of the first transmission component, the first connecting rod, and the second connecting rod.

[0022] In one possible implementation, when the lifting device is in the first state, the distance between the third end and the base is equal to the distance between the first end and the base. When the lifting device is in the second state, the distance between the third end and the base is equal to the distance between the first end and the base.

[0023] Understandably, both the first end of the first link and the third end of the second link are connected to the mounting component. When the lifting device is in the first and second states, the distance between the third end of the second link and the base is equal to the distance between the first end of the first link and the base. Thus, when the lifting device is in the first and second states, the distance between the connection point of the mounting component and the first link and the base is equal to the distance between the connection point of the mounting component and the second link and the base. This means that the connection points of the mounting component with the first and second links can move synchronously relative to the base, preventing the mounting component from tilting during operation and ensuring smooth lifting.

[0024] In one possible implementation, the lifting device further includes a first connecting rod. The first connecting rod is fixedly connected between the first connecting rod and the second connecting rod. This improves the structural strength of the lifting device, making it more stable and preventing damage from external forces.

[0025] In one possible implementation, the lifting device further includes a mounting shaft, a connecting member, and a torsion spring. The mounting shaft is fixed to the base. The connecting member includes a first connecting end and a second connecting end. Both the first connecting end and the second connecting end are rotatably connected to the mounting shaft. The second connecting end is connected to a driving member. The torsion spring includes a body portion, a first extension portion, and a second extension portion. The body portion is fixedly connected to the first extension portion and the second extension portion. The body portion is sleeved on the mounting shaft. The first extension portion is located on the connecting member. The second extension portion is located on the first transmission member.

[0026] In this way, when the mounting component is subjected to an external force and tends to move in the second direction, the first extension of the torsion spring can abut against the connecting component, and the second extension of the torsion spring can abut against the first transmission component, so that there is no relative rotation between the connecting component and the first transmission component, thereby allowing the mounting component to remain stationary relative to the base. In other words, the torsion spring in this embodiment can provide a buffering effect for the lifting device, so that the mounting component can remain stationary relative to the base even when subjected to an external force, which is beneficial to improving the user experience.

[0027] In one possible implementation, during the transition of the lifting device from a first state to a second state, the driving member drives the connecting member to rotate relative to the base in a first rotational direction. The first transmission member, under the cooperative action of the first extension and the second extension, moves synchronously with the connecting member.

[0028] Thus, when the connector rotates relative to the base in the first rotational direction, the connector can drive the torsion spring to rotate relative to the base in the same direction via its first extension. At this time, the second extension of the torsion spring can drive the first transmission member to rotate synchronously relative to the base in the first rotational direction (including rotating in the same direction and at the same speed). In other words, the first transmission member can rotate relative to the base in the first rotational direction under the action of the second extension of the torsion spring.

[0029] In one possible implementation, the second end of the first transmission member further has a rotating protrusion. The rotating protrusion is positioned directly opposite the connecting member in the circumferential direction of the mounting shaft. During the switching process of the lifting device from the second state to the first state, the driving member drives the connecting member to rotate relative to the mounting shaft in the second rotational direction. Under the cooperative action of the rotating protrusion and the connecting member, the first transmission member rotates relative to the base in the second rotational direction.

[0030] Thus, when the connecting member rotates relative to the base in the second rotational direction, the connecting member can press against the rotating protrusion of the first transmission member in the second rotational direction, allowing the first transmission member to rotate synchronously with the connecting member in the second rotational direction (including rotating in the same direction and at the same speed). In other words, the first transmission member can rotate relative to the base in the second rotational direction under the combined action of the connecting member and the rotating protrusion.

[0031] In one possible implementation, the base further has a first protrusion. The first connecting end has a first branch and a second branch spaced apart. The first protrusion is located between the first branch and the second branch. The mounting shaft is sequentially inserted through the first branch, the first protrusion, and the second branch. The body portion abuts between the first protrusion and the second branch. The first protrusion abuts against the first branch.

[0032] It is understood that in this embodiment, the main body of the torsion spring abuts against the first protrusion of the base and the second branch of the connector. The first protrusion of the base abuts against the first branch of the connector, which allows for a large static friction force between the first protrusion of the base and the first branch of the connector, that is, a large static friction force between the connector and the base. Thus, regardless of the position of the mounting member, the first transmission member and the base can remain relatively stationary. In other words, when the lifting device is in any state, the mounting member can be suspended without shaking.

[0033] In one possible implementation, the lifting device further includes a first rod and a second rod. The first rod has a first movable end and a second movable end. The second rod has a third movable end and a fourth movable end. The first movable end is rotatably connected to a second connecting end. The second movable end is rotatably connected to the third movable end. The fourth movable end is connected to a driving member. During the switching process of the lifting device from a first state to a second state, the driving member drives the second rod to rotate relative to the base in a second rotation direction, the first rod rotates relative to the second rod in a first rotation direction, and the connecting member rotates relative to the first rod in the first rotation direction. During the switching process of the lifting device from a second state to a first state, the driving member drives the second rod to rotate relative to the base in a first rotation direction, the first rod rotates relative to the second rod in a second rotation direction, and the connecting member rotates relative to the first rod in the second rotation direction.

[0034] It is understood that in this embodiment, the driving component can be connected to the connecting component sequentially via the second rod and the first rod, and then connected to the first transmission component via the connecting component. This allows for multiple options in the positioning of the driving component, making its positioning quite flexible.

[0035] In one possible implementation, the fourth movable end is provided with a stop protrusion. The base also includes a baffle. The stop protrusion and the baffle are arranged along a second rotation direction. During the switching process of the lifting device from the first state to the second state, the second rod rotates relative to the base along the second rotation direction, and the stop protrusion moves along the direction closer to the baffle.

[0036] Thus, when the mounting component is subjected to an external force and tends to move in the second direction, the first rod, under the action of the connecting member, tends to rotate relative to the second rod in the second rotation direction. The second rod, under the action of the first rod, tends to rotate relative to the base in the second rotation direction. At this time, the stop protrusion of the second rod can abut against the baffle, allowing the second rod to remain stationary relative to the base, and the first rod to remain stationary relative to the base, thereby allowing the mounting component to remain stationary relative to the base. That is, even when subjected to an external force, the mounting component in the lifting device of this embodiment can remain stationary relative to the base, which improves the user experience and protects the drive components, thus extending the service life of the lifting device.

[0037] In one possible implementation, when the lifting device is in the first and second states, the opening of the angle between the first and second rods both faces the second direction. The lifting device also includes a third state. When the lifting device is in the third state, the distance between the mounting member and the base is equal to the second spacing. The angle formed by the first and second rods is 180°, or the opening of the angle formed by the first and second rods faces the first direction.

[0038] Thus, when the lifting device is in the third state and the angle between the first and second rods is 180°, even if the mounting part is subjected to external force and has a tendency to move along the second direction, since the relative position between the first and second rods is a dead point, the first and second rods will not rotate relative to each other, thereby allowing the mounting part to remain stationary relative to the base.

[0039] When the lifting device is in the third state, and the opening of the angle between the first and second rods faces the first direction, even if the mounting component is subjected to external force and tends to move along the second direction, the first rod, under the action of the connecting member, tends to rotate relative to the second rod in the second rotation direction. The second rod, under the action of the first rod, tends to rotate relative to the base in the second rotation direction. At this time, the stop protrusion of the second rod can abut against the baffle, thereby allowing the second rod to remain stationary relative to the base, and the first rod to remain stationary relative to the base, thus allowing the mounting component to remain stationary relative to the base.

[0040] In other words, in the second state, the lifting device in this embodiment can also control the second rod to continue rotating relative to the base in the second rotation direction to the third state, so that the stop protrusion of the second rod can contact part of the base, and the included angle between the first rod and the second rod can be equal to 180° or the opening of the included angle can face the first direction, thereby providing a buffering effect for the lifting device, so that the mounting part can remain stationary relative to the base even if it is subjected to external force, which is beneficial to improving the user experience, and at the same time can protect the driving part and extend the service life of the lifting device.

[0041] In one possible implementation, the lifting device further includes an electrical connector, a sensor, and a magnetic component. Both the electrical connector and the sensor are fixed to the base. The magnetic component is fixed to the first transmission component or the first connecting rod. The electrical connector is electrically connected to the sensor. In this way, the lifting device can detect the position of the installed component relative to the base through the cooperation between the magnetic component and the sensor, which helps improve the control accuracy and motion accuracy of the lifting device, thereby enhancing the user experience.

[0042] In one possible implementation, the magnetic component is fixed to the first link. The magnetic component is positioned near a first sliding protrusion of the first link, relative to a first end and a second end of the first link.

[0043] Understandably, compared to lifting devices that mount magnetic components to the mounting component, when the relative distance between the mounting component and the base is large, the magnetic component may exceed the sensor's detection range, thus reducing the sensor's accuracy in detecting the mounting component's position, or even preventing the sensor from detecting the mounting component's position. However, in this embodiment, the lifting device fixes the magnetic component to the first connecting rod, with the magnetic component positioned closer to the first sliding protrusion than the first and second ends of the first connecting rod. When the lifting device switches between the first and second states, the displacement of the magnetic component relative to the base is less than the displacement of the first end of the first connecting rod relative to the base, but greater than the displacement of the second end of the first connecting rod relative to the base. That is, the displacement of the magnetic component relative to the base is moderate. Thus, during the operation of the lifting device, the movement of the magnetic component will not exceed the sensor's detection range, and it is easily detected by the sensor, which helps improve the sensor's detection accuracy, thereby improving the control accuracy of the lifting device.

[0044] Secondly, a camera decorative assembly is provided. The camera decorative assembly includes a camera decorative piece and the aforementioned lifting device, with the camera decorative piece mounted on a mounting component. The camera decorative assembly in this embodiment has a relatively simple structure, low manufacturing cost, and a large lifting stroke.

[0045] Thirdly, an electronic device is provided. The electronic device includes a housing, a camera module, and the aforementioned camera decorative component. The camera decorative component is installed inside the housing. The housing has a light-transmitting hole, and the light-inlet hole of the camera module faces the light-transmitting hole. The camera decorative component is installed within the light-transmitting hole. The camera decorative component of the electronic device in this embodiment has a relatively simple structure, low manufacturing cost, and a large lifting stroke. Attached Figure Description

[0111] The embodiments of this application are described below with reference to the accompanying drawings.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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 3 The 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 1And 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.

[0119] 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.

[0120] For example, the electronic device 1000 may further include a camera decorative 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 decorative assembly 300 may be fixed to the back cover 202. The projection of the camera decorative assembly 300 onto the plane of the back cover 202 may cover the light-transmitting hole 203.

[0121] In other embodiments, when the electronic device 1000 is a device of other types, the electronic device 1000 may not include the screen 100.

[0122] Figure 4a yes Figure 3 The diagram shows the structure of the camera trim assembly 300 of the electronic device 1000 in some embodiments when it is in a first state. Figure 4b yes Figure 4a The diagram shows the structure of the camera decorative component 300 in its second state. Figure 5 yes Figure 4a The diagram shows an exploded view of the camera decorative component 300 in some embodiments. Figure 6 yes Figure 5 The diagram shows an exploded view of the lifting device 310 in some embodiments.

[0123] like Figures 4a to 6As shown, the camera decoration assembly 300 may include a lifting device 310 and a camera decoration component 320. The camera decoration component 320 may be mounted on the lifting device 310. The lifting device 310 may be used to drive the camera decoration component 320 to move along a first direction or a second direction. The first direction and the second direction may be opposite directions. In this embodiment, both the first direction and the second direction may be parallel to the thickness direction of the camera decoration component 320. That is, both the first direction and the second direction may be parallel to the Z-axis direction. The first direction may be the positive direction of the Z-axis, and the second direction may be the negative direction of the Z-axis.

[0124] For example, the lifting device 310 may include a transmission mechanism 10, a buffer mechanism 20, a drive member 28, a base 30, a mounting member 40, and an electrical connector 50. The transmission mechanism 10, buffer mechanism 20, drive member 28, and electrical connector 50 can all be mounted on the base 30. The mounting member 40 can be mounted on the transmission mechanism 10. The mounting member 40 can be used to mount the camera decoration 320. The drive member 28 can be electrically connected to the motherboard (not shown) of the electronic device 1000 via the electrical connector 50. The motherboard can input electrical signals to the drive member 28 via the electrical connector 50, so that the drive member 28 can drive the transmission mechanism 10 to move the mounting member 40 and the camera decoration 320 together along a first direction or a second direction, thereby achieving the lifting and lowering of the camera decoration 320 relative to the base 30.

[0125] For example, the lifting device 310 may further include a sensor 60 and a magnetic element 70. The sensor 60 and the magnetic element 70 may be mounted on the base 30 and the transmission mechanism 10, respectively. The sensor 60 may be electrically connected to the electrical connector 50. The sensor 60 may cooperate with the magnetic element 70 to detect the movement of the transmission mechanism 10, thereby detecting the relative distance between the mounting member 40 and the base 30.

[0126] For example, the camera decoration component 300 may have a first state (such as...) Figure 4a (as shown) and the second state (as shown) Figure 4b (As shown). The camera trim 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 2 (As shown).

[0127] In other embodiments, the lifting device 310 may not include the mounting member 40. The camera trim 320 may also be mounted on the transmission mechanism 10. In some other embodiments, the lifting device 310 may not include the electrical connector 50, the sensor 60, and the magnetic component 70.

[0128] The specific structure of the lifting device 310 will be described below with reference to the accompanying drawings.

[0129] Figure 7 yes Figure 6 The diagram shows an exploded view of the buffer mechanism 20 in some embodiments. Figure 8a yes Figure 7 The diagram shown is a structural schematic of the connector 24 in some embodiments. Figure 8b yes Figure 8a The structural schematic diagram of connector 24 shown from another perspective.

[0130] like Figures 7 to 8b As shown, the buffer mechanism 20 may include a mounting shaft 21, a torsion spring 22, a first sleeve 23, a connector 24, a first rod 25, a second rod 26, a first rotating shaft 271, a second rotating shaft 272, and a second sleeve 29. The connector 24 may include a first connecting end 241, a middle portion 242, and a second connecting end 243 connected sequentially. Exemplarily, the first connecting end 241, the middle portion 242, and the second connecting end 243 may be arranged along the width direction of the connector 24. The first connecting end 241 may include a first branch 2411, a third branch 2412, and a second branch 2413 arranged sequentially at intervals along the length extension direction of the connector 24. A first gap 24a may exist between the first branch 2411 and the third branch 2412 of the connector 24. A second gap 24b may exist between the third branch 2412 and the second branch 2413. In this embodiment, the thickness direction of the connector 24 may be parallel to the plane containing the X-axis and Z-axis. The length direction of connector 24 can be parallel to the Y-axis direction.

[0131] For example, the first branch 2411, the second branch 2413, and the third branch 2412 may each have a first hole 2411a, a second hole 2413a, and a third hole 2412a, respectively. The first hole 2411a, the second hole 2413a, and the third hole 2412a can all be circular holes and can be coaxially arranged. A first gap 24a can connect the first hole 2411a and the third hole 2412a. A second gap 24b can connect the third hole 2412a and the second hole 2413a. The first gap 24a can connect to the second gap 24b through the third hole 2412a. For example, the inner diameter of the third hole 2412a can be larger than the inner diameter of the first hole 2411a and the inner diameter of the second hole 2413a.

[0132] Exemplarily, the middle portion 242 of the connector 24 may have a first mounting groove 2421. The first mounting groove 2421 may communicate with the second gap 24b. The first mounting groove 2421 may be positioned closer to the second branch 2413 relative to the third branch 2412. The first mounting groove 2421 may have a groove bottom surface 2421a. The groove bottom surface 2421a of the first mounting groove 2421 may be positioned towards the first connecting end 241 of the connector 24.

[0133] It should be noted that although the connector 24 is described in this embodiment as being divided into three parts (i.e., the first connecting end 241, the middle part 242, and the second connecting end 243), it does not affect the fact that the connector 24 is an integrally formed structure, that is, the first connecting end 241, the middle part 242, and the second connecting end 243 can be integrally formed.

[0134] Figure 9a yes Figure 7 The diagram shows a partial assembly structure of the buffer mechanism 20 in some embodiments. Figure 9b yes Figure 9a The diagram shown is a structural schematic from another perspective. Figure 10a yes Figure 5 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along point AA. Figure 10b yes Figure 9a The diagram shows a partial cross-sectional view of one embodiment of the structure cut along point BB.

[0135] like Figures 9a to 10b As shown, the first sleeve 23 may include a first ring portion 231, a second ring portion 232, and a limiting protrusion 233. Figure 7 The specific structure of the first sleeve 23 is also illustrated in the diagram. The first ring portion 231 can be located on one side of the second ring portion 232 and can be fixedly connected to the second ring portion 232. The outer diameter of the second ring portion 232 can be larger than the outer diameter of the first ring portion 231. The limiting protrusion 233 can be located on the side of the second ring portion 232 facing the first ring portion 231 and is fixedly connected to the outer peripheral side of the first ring portion 231 and the surface of the second ring portion 232 facing the first ring portion 231. The inner diameter of the first ring portion 231 can be equal to the inner diameter of the second ring portion 232. The inner space of the first ring portion 231 can communicate with the inner space of the second ring portion 232. The inner space of the first ring portion 231 and the inner space of the second ring portion 232 can together constitute the inner space 23a of the first sleeve 23. It should be noted that although the first sleeve 23 is described in this embodiment as being divided into three parts (i.e., the first ring 231, the second ring 232, and the limiting protrusion 233), it does not affect the fact that the first sleeve 23 is an integrally formed structure, that is, the first ring 231, the second ring 232, and the limiting protrusion 233 can be integrally formed.

[0136] For example, a portion of the first ring portion 231 of the first sleeve 23 can pass through the third hole 2412a of the connector 24, and a portion can be located in the first gap 24a of the connector 24. The second ring portion 232 of the first sleeve 23 can be located on the side of the third branch 2412 of the connector 24 facing the second branch 2413, that is, the second ring portion 232 can be located in the second gap 24b of the connector 24. The second ring portion 232 can be spaced apart from the third branch 2412.

[0137] For example, the third branch 2412 of the connector 24 may also have a notch 2412b. Figure 8b The structure of notch 2412b is also illustrated in the diagram. Notch 2412b can connect to the third hole 2412a. At least part of the limiting protrusion 233 of the first sleeve 23 can be located in notch 2412b. The limiting protrusion 233 can cooperate with notch 2412b to limit the first sleeve 23, thereby preventing relative rotation between the first sleeve 23 and the connecting member 24.

[0138] For example, the mounting shaft 21 can be a pin. The mounting shaft 21 can be sequentially inserted into the first hole 2411a of the connector 24, the inner space 23a of the first sleeve 23, and the second hole 2413a of the connector 24. At this time, the connector 24 can rotatably connect to the mounting shaft 21. The connector 24 can rotate about the central axis of the mounting shaft 21 in a first rotation direction a, or in a second rotation direction b. The first rotation direction a can be opposite to the second rotation direction b. It should be noted that in this application, any two components can be rotatably connected by providing holes, pins, fasteners, or other methods in one or more of the components. This application does not limit the method of rotatable connection.

[0139] Please refer to it again. Figures 9a to 10b The second sleeve 29 can be located in the second gap 24b of the connector 24. The second sleeve 29 can be located between the second ring portion 232 of the first sleeve 23 and the second branch portion 2413 of the connector 24. The second sleeve 29 can be sleeved on the mounting shaft 21. The torsion spring 22 can be sleeved on the second sleeve 29. At least a portion of the torsion spring 22 can be located in the second gap 24b of the connector 24, and between the second ring portion 232 of the first sleeve 23 and the second branch portion 2413 of the connector 24.

[0140] For example, the torsion spring 22 may include a body portion 22a, a first extension portion 22b, and a second extension portion 22c. Figure 7The structure of the torsion spring 22 is also illustrated. The body portion 22a of the torsion spring 22 can be fixedly connected to the first extension portion 22b and the second extension portion 22c. The first extension portion 22b can be spaced apart from the second extension portion 22c. The body portion 22a of the torsion spring 22 can be sleeved on the second sleeve 29. The body portion 22a of the torsion spring 22 can be located in the second gap 24b of the connector 24, and between the second ring portion 232 of the first sleeve 23 and the second branch portion 2413 of the connector 24.

[0141] Exemplarily, the first extension 22b of the torsion spring 22 can be located within the first mounting groove 2421 of the connector 24. The second extension 22c of the torsion spring 22 can be positioned away from the middle portion 242 of the connector 24 relative to the first extension 22b. The dimensions of the first mounting groove 2421 of the connector 24 and the first extension 22b of the torsion spring 22 can be approximately the same. This allows the first mounting groove 2421 of the connector 24 to limit the first extension 22b of the torsion spring 22, thereby preventing displacement of the first extension 22b of the torsion spring 22 relative to the connector 24 along the length direction of the connector 24 (i.e., the Y-axis direction in this embodiment). In other embodiments, the first extension 22b of the torsion spring 22 can also be fixed within the first mounting groove 2421 of the connector 24. In some other embodiments, the first mounting groove 2421 may not be provided. The first extension 22b can also overlap the surface of the middle portion 242 of the connector 24 facing the first connecting end 241, or be disposed opposite to the surface of the middle portion 242 facing the first connecting end 241.

[0142] It should be noted that although the torsion spring 22 is described in this embodiment as being divided into three parts (i.e., the main body 22a, the first extension 22b, and the second extension 22c), this does not affect the fact that the torsion spring 22 is an integrally formed structure, that is, the main body 22a, the first extension 22b, and the second extension 22c can be integrally formed.

[0143] In some embodiments, the buffer mechanism 20 may not include the second sleeve 29. The body portion 22a of the torsion spring 22 may also be directly sleeved on the mounting shaft 21.

[0144] Figure 11 yes Figure 7 The diagram shows a partial assembly structure of the buffer mechanism 20 in some embodiments. Figure 12 yes Figure 7 The diagram shows an assembly structure of the buffer mechanism 20 in some embodiments.

[0145] like Figure 7 , Figure 11 as well as Figure 12As shown, the first rod 25 may have a first movable end 251 and a second movable end 252. The first movable end 251 of the first rod 25 can be rotatably connected to the second connecting end 243 of the connector 24. For example, the first movable end 251 of the first rod 25 may have a first through hole 251a. The second connecting end 243 of the connector 24 may have a fourth hole 243a. The fourth hole 243a may be positioned opposite the first through hole 251a. The first rotating shaft 271 may pass through the first through hole 251a of the first rod 25 and the fourth hole 243a of the connector 24. At this time, the connector 24 may rotate relative to the first movable end 251 of the first rod 25 about the central axis of the fourth hole 243a, along a first rotation direction a or a second rotation direction b. The central axis of the fourth hole 243a may be parallel to and spaced apart from the central axis of the mounting shaft 21. That is, the rotation center of the connector 24 relative to the first rod 25 may be parallel to and spaced apart from the mounting shaft 21.

[0146] For example, the second rod 26 may have a third movable end 261 and a fourth movable end 262. The third movable end 261 of the second rod 26 may be rotatably connected to the second movable end 252 of the first rod 25. For example, the second movable end 252 of the first rod 25 may have a second through hole 252a. The third movable end 261 of the second rod 26 may have a third through hole 261a. The second through hole 252a of the first rod 25 may be positioned opposite the third through hole 261a of the second rod 26. The second rotating shaft 272 may pass through the second through hole 252a of the first rod 25 and the third through hole 261a of the second rod 26, so that the first rod 25 may rotate relative to the third movable end 261 of the second rod 26 about the central axis of the third through hole 261a, along a first rotation direction a or a second rotation direction b.

[0147] Figure 13a yes Figure 7 The diagram shows an assembly structure of the buffer mechanism 20 in some embodiments. Figure 13b yes Figure 13a The diagram shows a partial cross-sectional view of one embodiment of the structure cut along point CC.

[0148] like Figure 13a and Figure 13b As shown, the drive member 28 can be located on the side of the middle portion 242 of the connector 24 facing away from the first connecting end 241. The drive member 28 can be located on the same side of the first rod 25 and the second rod 26. The drive member 28 may include a connected output shaft 28a and a drive member body 28b. The drive member body 28b can be electrically connected to the motherboard (not shown) of the electronic device 1000. When an electrical signal is input to the drive member body 28b, the output shaft 28a can rotate along a first rotation direction a or a second rotation direction b.

[0149] For example, the output shaft 28a of the drive member 28 can be fixedly connected to the fourth movable end 262 of the second rod 26. For instance, the fourth movable end 262 of the second rod 26 can have a fourth through hole 262a. The fourth through hole 262a of the second rod 26 can be sleeved on the output shaft 28a of the drive member 28. The fourth through hole 262a of the second rod 26 and the output shaft 28a can be in a flat fit, so that the second rod 26 can rotate synchronously with the output shaft 28a. In other words, when the drive member body 28b receives an electrical signal, the output shaft 28a can rotate along a first rotation direction a or a second rotation direction b, and drive the second rod 26 to rotate relative to the output shaft 28a along the first rotation direction a or the second rotation direction b, with the central axis of the output shaft 28a as the rotation center. In other embodiments, the second rod 26 can also be connected to the output shaft 28a of the drive member 28 by other means such as a worm gear or gear.

[0150] Figure 14a yes Figure 6 The diagram shows the structure of the base 30 in some embodiments. Figure 14b yes Figure 14a The diagram shows the structure of the base 30 from another perspective.

[0151] like Figure 14a and Figure 14b As shown, the base 30 may include a first part 31 and a second part 32 connected together. The first part 31 of the base 30 may be located on one side of the second part 32. The first part 31 of the base 30 may include a first sidewall 31a, a second sidewall 31b, and a top plate 31c. The first sidewall 31a and the second sidewall 31b may be arranged opposite each other and spaced apart. The top plate 31c may be located on the same side of the first sidewall 31a and the second sidewall 31b, and may be fixedly connected to the first sidewall 31a and the second sidewall 31b. The first sidewall 31a, the second sidewall 31b, and the top plate 31c may together enclose a first space 30a in the first part 31. The second part 32 may be a hollow structure, generally annular. The second part 32 may have a second space 30b. The second space 30b may communicate with the first space 30a. The second space 30b may be used to accommodate a camera decorative piece 320 (please refer to...). Figure 4a (As shown). The first space 30a and the second space 30b can together form the installation space of the base 30.

[0152] Exemplarily, the base 30 may further include a first protrusion 33 and a second protrusion 34. Both the first protrusion 33 and the second protrusion 34 may be located in the first space 30a of the base 30 and fixedly connected to the first portion 31 of the base 30. The first protrusion 33 and the second protrusion 34 may be arranged opposite to each other and spaced apart. Both the first protrusion 33 and the second protrusion 34 may be fixedly connected to the top plate 31c of the base 30 and spaced apart from the first sidewall 31a and the second sidewall 31b. In other embodiments, the first protrusion 33 may also be fixedly connected to the surface of the first sidewall 31a facing the second sidewall 31b. The first protrusion 33 may be spaced apart from the top plate 31c, or the first protrusion 33 may be fixedly connected to the top plate 31c.

[0153] Figure 15a yes Figure 6 The diagram shows the assembly structure of the base 30, buffer mechanism 20 and drive component 28 in some embodiments. Figure 15b yes Figure 15a The diagram shown is a structural schematic from another perspective. Figure 16 yes Figure 5 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along point AA.

[0154] like Figures 15a to 16 As shown, both the buffer mechanism 20 and the drive member 28 can be installed within the first space 30a of the base 30. The mounting shaft 21 can be installed in the first protrusion 33 and the second protrusion 34. For example, both the first protrusion 33 and the second protrusion 34 can have mounting holes, and the mounting shaft 21 can be sequentially inserted into the mounting holes of the first protrusion 33 and the second protrusion 34. The drive member 28 can be located on the side of the mounting shaft 21 facing away from the second portion 32 of the base 30. The first rod 25 and the second rod 26 can both be located on the side of the first protrusion 33 of the base 30 facing away from the second protrusion 34.

[0155] For example, the first branch 2411 of the connector 24 can be located on the side of the first protrusion 33 of the base 30 facing away from the second protrusion 34. The second branch 2413 and the third branch 2412 of the connector 24 can both be located between the first protrusion 33 and the second protrusion 34 of the base 30. At this time, the first sleeve 23, the body portion 22a of the torsion spring 22, and the second sleeve 29 can also all be located between the first protrusion 33 and the second protrusion 34 of the base 30. The second branch 2413 and the third branch 2412 of the connector 24 can both be spaced apart from the first protrusion 33 and the second protrusion 34 of the base 30.

[0156] In this embodiment, the body portion 22a of the torsion spring 22 can be in a compressed state in the axial direction of the mounting shaft 21 (i.e., the Y-axis direction). The body portion 22a of the torsion spring 22 can abut against the second ring portion 232 of the first sleeve 23 and the second branch portion 2413 of the connector 24. At this time, the first ring portion 231 of the first sleeve 23 can abut against the first protrusion 33 of the base 30 under the action of the body portion 22a of the torsion spring 22, so that the first protrusion 33 of the base 30 can abut against the first branch portion 2411 of the connector 24. In other words, the first protrusion 33 of the base 30 can abut against the first branch portion 2411 of the connector 24 under the action of the torsion spring 22 and the first sleeve 23. In this way, there can be a large static friction between the first branch portion 2411 of the connector 24 and the first protrusion 33 of the base 30, that is, there can be a large static friction between the connector 24 and the base 30.

[0157] Exemplarily, the base 30 may also have a small hole 313. The small hole 313 may penetrate through the first sidewall 31a of the base 30. The small hole 313 may be positioned directly opposite the fourth through hole 262a of the second rod 26. The buffer mechanism 20 may also include a third rotating shaft 273. The third rotating shaft 273 may be sequentially inserted into the fourth through hole 262a and the small hole 313. In this way, the connection between the buffer mechanism 20 and the base 30 can be made more stable, thereby making the connection between the drive member 28 and the base 30 more stable.

[0158] In some embodiments, there may be no gap between the second ring portion 232 of the first sleeve 23 and the third branch portion 2412 of the connector 24. That is, the side of the second ring portion 232 of the first sleeve 23 facing the first ring portion 231 can contact the side of the third branch portion 2412 of the connector 24 facing the second branch portion 2413.

[0159] In some embodiments, the buffer mechanism 20 may not include the first sleeve 23, and the connector 24 may not include the third branch 2412. In this case, the body portion 22a of the torsion spring 22 may be located between the first protrusion 33 of the base 30 and the second branch 2413 of the connector 24. The first protrusion 33 of the base 30 may abut against the first branch 2411 of the connector 24 under the action of the body portion 22a of the torsion spring 22.

[0160] Figure 17 yes Figure 5 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 when it is in the first state, cut along DD. Figure 18 yes Figure 17 The diagram shown is a schematic of the structure in its second state.

[0161] like Figure 17 and Figure 18As shown, when the lifting device 310 is in the first state (e.g.) Figure 17 As shown, a first included angle α1 can be formed between the connector 24 and the first plane. The first plane can be perpendicular to the thickness direction of the base 30. In this embodiment, the first plane can also be perpendicular to the Z-axis direction. The first plane can be parallel to the top plate 31c of the base 30. The first included angle α1 can be the angle formed by the straight line connecting the central axis of the first hole 2411a (which in this embodiment is also the central axis of the mounting shaft 21) and the central axis of the fourth hole 243a (which in this embodiment is also the central axis of the first through hole 251a) of the connector 24 and the first plane. For example, the angle α1 can be less than 90°.

[0162] The included angle formed by the first member 25 and the second member 26 can be a second included angle β1. The second included angle β1 can be the angle formed by the lines connecting the central axis of the first through hole 251a, the central axis of the second through hole 252a (which in this embodiment is also the central axis of the third through hole 261a), and the central axis of the fourth through hole 262a. For example, the angle of the second included angle β1 can be less than 90°. The opening of the second included angle β1 can face a second direction.

[0163] For example, when the lifting device 310 is in the second state (e.g. Figure 18 As shown, a third included angle α2 can be formed between the connector 24 and the first plane. The included angle formed by the first member 25 and the second member 26 can be a fourth included angle β2. The third included angle α2 can be greater than the first included angle α1. The fourth included angle β2 can be greater than the second included angle β1. For example, the angle of the third included angle α2 can be less than 90°. The angle of the fourth included angle β2 can be greater than 90°. Wherein, the opening of the fourth included angle β2 can face the second direction.

[0164] For example, during the transition from the first state to the second state of the lifting device 310, the drive body 28b of the drive member 28 can receive a first electrical signal. The output shaft 28a of the drive member 28 can rotate relative to the base 30 along the second rotation direction b, causing the second rod 26 to rotate relative to the base 30 about the central axis of the output shaft 28a (which in this embodiment is also the central axis of the fourth through hole 262a) along the second rotation direction b. The first rod 25 can rotate relative to the second rod 26 about the central axis of the second through hole 252a (which in this embodiment is also the central axis of the third through hole 261a) along the first rotation direction a. The connecting member 24 can rotate relative to the base 30 about the central axis of the mounting shaft 21 along the first rotation direction a. At this time, the angle between the connecting member 24 and the first plane can gradually increase. The angle between the first rod 25 and the second rod 26 can gradually increase.

[0165] For example, during the switching process of the lifting device 310 from the second state to the first state, the drive body 28b of the drive member 28 can input a second electrical signal, and the output shaft 28a of the drive member 28 can rotate relative to the base 30 along the first rotation direction a, thereby driving the second rod 26 to rotate relative to the base 30 with the central axis of the output shaft 28a (which in this embodiment is also the central axis of the fourth through hole 262a) as the rotation center, along the first rotation direction a. The first rod 25 can rotate relative to the second rod 26 with the central axis of the second through hole 252a (which in this embodiment is also the central axis of the third through hole 261a) as the rotation center, along the second rotation direction b. The connecting member 24 can rotate relative to the base 30 with the central axis of the mounting shaft 21 as the rotation center, along the second rotation direction b. At this time, the angle between the connecting member 24 and the first plane can gradually decrease. The angle between the first rod 25 and the second rod 26 can gradually decrease.

[0166] Figure 19a yes Figure 6 The diagram shows the structure of the first transmission component 11 in some embodiments. Figure 19b yes Figure 19a The diagram shows the structure of the first transmission component 11 from another perspective.

[0167] like Figure 19a and Figure 19b As shown, the transmission mechanism 10 may include a first transmission member 11 and a second transmission member 12 (please refer to...). Figure 6 (As shown). The first transmission member 11 may include a first end 111 and a second end 112. The first end 111 and the second end 112 may be arranged along the width direction (i.e., the X-axis direction in this embodiment) of the first transmission member 11. The second end 112 may include a first mounting portion 1121, a second mounting portion 1122, a third mounting portion 1123, and a fourth mounting portion 1124, which are sequentially spaced apart along the length direction (i.e., the Y-axis direction in this embodiment) of the first transmission member 11. A first gap 11a may exist between the first mounting portion 1121 and the second mounting portion 1122. A second gap 11b may exist between the second mounting portion 1122 and the third mounting portion 1123. A third gap 11c may exist between the third mounting portion 1123 and the fourth mounting portion 1124.

[0168] For example, the first mounting portion 1121, the second mounting portion 1122, the third mounting portion 1123, and the fourth mounting portion 1124 may each have a first mounting hole 1121a, a second mounting hole 1122a, a third mounting hole 1123a, and a fourth mounting hole 1124a, respectively. The first mounting hole 1121a, the second mounting hole 1122a, the third mounting hole 1123a, and the fourth mounting hole 1124a can all be circular holes and can be coaxially arranged. The first gap 11a can connect the first mounting hole 1121a and the second mounting hole 1122a. The second gap 11b can connect the second mounting hole 1122a and the third mounting hole 1123a. The third gap 11c can connect the third mounting hole 1123a and the fourth mounting hole 1124a. The first gap 11a can connect to the second gap 11b through the second mounting hole 1122a. The second gap 11b can connect to the third gap 11c through the third mounting hole 1123a. For example, the inner diameter of the second mounting hole 1122a may be larger than the inner diameter of the first mounting hole 1121a, the inner diameter of the third mounting hole 1123a, and the inner diameter of the fourth mounting hole 1124a.

[0169] For example, the first transmission member 11 may also have a second mounting groove 113. The second mounting groove 113 may be spaced apart from the first mounting hole 1121a, the second mounting hole 1122a, the third mounting hole 1123a and the fourth mounting hole 1124a.

[0170] Figure 20a yes Figure 6 The diagram shows a partial assembly structure of the lifting device 310 in some embodiments. Figure 20b yes Figure 20a The diagram shows the structure from another perspective. Figure 20c yes Figure 5 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along point AA. It should be noted that, for ease of understanding, Figure 20b The structure of base 30 is omitted.

[0171] like Figures 20a to 20cAs shown, the first transmission member 11 can be located inside the base 30. The first transmission member 11 can be connected to the buffer mechanism 20. The mounting shaft 21 of the buffer mechanism 20 can also sequentially pass through the first mounting hole 1121a, the second mounting hole 1122a, the third mounting hole 1123a, and the fourth mounting hole 1124a at the second end 112 of the first transmission member 11. In this case, the second end 112 of the first transmission member 11 can be rotatably connected to the mounting shaft 21. The first transmission member 11 can rotate relative to the mounting shaft 21 in a first rotation direction a or a second rotation direction b. In other words, the second end 112 of the first transmission member 11 can be rotatably connected to the base 30 via the mounting shaft 21. The first transmission member 11 can rotate relative to the base 30 about the central axis of the mounting shaft 21, in the first rotation direction a or the second rotation direction b.

[0172] For example, the first mounting portion 1121 of the first transmission member 11 may be located on the side of the first branch 2411 of the connector 24 facing away from the third branch 2412. The second mounting portion 1122 may be located between the first protrusion 33 of the base 30 and the third branch 2412 of the connector 24. The third mounting portion 1123 may be located between the second branch 2413 of the connector 24 and the second protrusion 34 of the base 30. The fourth mounting portion 1124 may be located on the side of the second protrusion 34 of the base 30 facing away from the first protrusion 33. In this case, both the first branch 2411 of the connector 24 and the first protrusion 33 of the base 30 may be located in the first gap 11a of the first transmission member 11, and the second protrusion 34 of the base 30 may be located in the third gap 11c of the first transmission member 11. The first protrusion 33 of the base 30 may be located between the first support 2411 of the connector 24 and the second mounting portion 1122 of the first transmission member 11, and the second protrusion 34 of the base 30 may be located between the third mounting portion 1123 and the fourth mounting portion 1124 of the first transmission member 11.

[0173] For example, the third branch 2412 of the connector 24, the first sleeve 23, the body portion 22a of the torsion spring 22, the second sleeve 29, and the second branch 2413 of the connector 24 can all be located in the second gap 11b of the first transmission member 11. That is, the third branch 2412 of the connector 24, the first sleeve 23, the body portion 22a of the torsion spring 22, the second sleeve 29, and the second branch 2413 of the connector 24 can all be located between the second mounting portion 1122 and the third mounting portion 1123 of the first transmission member 11.

[0174] In some embodiments, the second end 112 of the first transmission member 11 may not include the third mounting portion 1123. The second protrusion 34 of the base 30 may be located between the fourth mounting portion 1124 of the first transmission member 11 and the second branch 2413 of the connector 24.

[0175] In some embodiments, the lifting device 310 may not include the buffer mechanism 20. The first transmission member 11 may be connected to the drive member 28.

[0176] Figure 21a yes Figure 20a The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along EE. Figure 21b yes Figure 20a The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along FF. Figure 22 yes Figure 20a The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along GG.

[0177] like Figures 21a to 22 As shown, the second extension 22c of the torsion spring 22 can pass through the second mounting groove 113 of the first transmission member 11. In this case, the first extension 22b and the second extension 22c of the torsion spring 22 can be located in the first mounting groove 2421 of the connector 24 and the second mounting groove 113 of the first transmission member 11, respectively. In some other embodiments, the first transmission member 11 may not have a second mounting groove 113. The second extension 22c of the torsion spring 22 can also be fixedly connected to the first transmission member 11.

[0178] For example, the torsion spring 22 can be in a compressed state in its radial direction. This compressed state can mean that the first extension 22b and the second extension 22c of the torsion spring 22 move in opposite directions, tending to open relative to each other. In this case, the first extension 22b of the torsion spring 22 can abut against the bottom surface 2421a of the first mounting groove 2421 of the connector 24, and the second extension 22c of the torsion spring 22 can abut against the wall of the second mounting groove 113 of the first transmission member 11.

[0179] For example, the second end 112 of the first transmission member 11 may also have a rotating protrusion 114. Figure 19a The specific structure of the rotating protrusion 114 is also illustrated. The rotating protrusion 114 can be provided directly opposite the connector 24 in the circumferential direction of the mounting shaft 21. There can be two rotating protrusions 114. The two rotating protrusions 114 can be located on the side opposite to the first end 111 of the second mounting portion 1122 and the third mounting portion 1123 of the first transmission member 11, respectively. Both rotating protrusions 114 can be provided directly opposite the middle portion 242 of the connector 24 in the circumferential direction of the mounting shaft 21. In this embodiment, the torsion spring 22 can be in a compressed state in its radial direction, so that the rotating protrusion 114 can abut against the connector 24 under the action of the torsion spring 22.

[0180] For example, when the connector 24 rotates relative to the base 30 in the first rotation direction a, the connector 24 can drive the torsion spring 22 to rotate relative to the base 30 in the first rotation direction a through the cooperation of the first mounting groove 2421 and the first extension 22b. At this time, the second extension 22c of the torsion spring 22 can press against the groove wall of the second mounting groove 113 of the first transmission member 11, so that the first transmission member 11 and the connector 24 can rotate synchronously relative to the base 30 with the central axis of the mounting shaft 21 as the rotation center in the first rotation direction a (including the same rotation direction and the same rotation speed). In other words, the first transmission member 11 can rotate relative to the base 30 with the central axis of the mounting shaft 21 as the rotation center in the first rotation direction a under the cooperation of the second extension 22c of the torsion spring 22 and the groove wall of the second mounting groove 113.

[0181] For example, when the connector 24 rotates relative to the base 30 in the second rotation direction b, the middle portion 242 of the connector 24 can press the rotating protrusion 114 of the first transmission member 11 in the second rotation direction b, so that the first transmission member 11 can rotate synchronously with the connector 24 about the central axis of the mounting shaft 21 in the second rotation direction b (including the same rotation direction and the same rotation speed). In other words, the first transmission member 11 can rotate relative to the base 30 about the central axis of the mounting shaft 21 in the second rotation direction b under the cooperation of the middle portion 242 of the connector 24 and the rotating protrusion 114.

[0182] In other words, under the combined action of the torsion spring 22 and the connecting member 24, the first transmission member 11 can rotate synchronously with the torsion spring 22 and the connecting member 24 relative to the base 30 with the central axis of the mounting shaft 21 as the rotation center, along the first rotation direction a or the second rotation direction b.

[0183] In other embodiments, the torsion spring 22 can also be in its natural state in the radial direction, that is, the first extension 22b and the second extension 22c of the torsion spring 22 do not have opposite movements and tend to open relative to each other. In this case, the first extension 22b and the second extension 22c can respectively overlap the bottom surface 2421a of the first mounting groove 2421 and the side wall of the second mounting groove 113. The rotating protrusion 114 can contact the connector 24, or there may be a gap between it and the connector 24.

[0184] In some other embodiments, there may be a gap between the first extension 22b and the bottom surface 2421a of the first mounting groove 2421, and / or there may be a gap between the second extension 22c and the side wall of the second mounting groove 113.

[0185] Figure 23 yes Figure 5The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 when it is in the first state, cut along DD. Figure 24 yes Figure 23 The diagram shown is a schematic of the structure in its second state.

[0186] like Figure 23 and Figure 24 As shown, during the transition of the lifting device 310 from the first state to the second state, the connecting member 24 can drive the first transmission member 11 to rotate relative to the base 30 around the central axis of the mounting shaft 21 in the first rotation direction a. There is no relative rotation between the connecting member 24 and the first transmission member 11; they can remain relatively stationary.

[0187] For example, during the transition of the lifting device 310 from the second state to the first state, the connecting member 24 can drive the first transmission member 11 to rotate relative to the base 30 about the central axis of the mounting shaft 21 in the second rotation direction b. There is no relative rotation between the connecting member 24 and the first transmission member 11, and the connecting member 24 and the first transmission member 11 can remain relatively stationary.

[0188] In other words, the first transmission member 11 can rotate relative to the base 30 with the central axis of the mounting shaft 21 as the rotation center, in either the first rotation direction a or the second rotation direction b, under the combined action of the driving member 28 and the buffer mechanism 20.

[0189] In other embodiments, the buffer mechanism 20 may not include the connector 24, the first rod 25, and the second rod 26. The drive member 28 may be connected to the first transmission member 11 and drive the first transmission member 11 to rotate relative to the base 30 in a first rotation direction a or in a second rotation direction b. In some other embodiments, the buffer mechanism 20 and the drive member 28 may also be in other forms.

[0190] Figure 25a yes Figure 6 The diagram shows the structure of the second transmission component 12 in some embodiments. Figure 25b yes Figure 25a The diagram shows the structure of the second transmission component 12 from another perspective.

[0191] like Figure 25a and Figure 25bAs shown, the second transmission component 12 may include a first connecting rod 121, a second connecting rod 122, a first connecting rod 123, and a second connecting rod 124. The first connecting rod 121 may be spaced apart from the second connecting rod 122. The first connecting rod 123 and the second connecting rod 124 may both be fixedly connected between the first connecting rod 121 and the second connecting rod 122. The first connecting rod 123 may be spaced apart from the second connecting rod 124. The first connecting rod 121 and the second connecting rod 122 may be symmetrical. It should be noted that although the second transmission component 12 is described in this embodiment as divided into four parts (i.e., the first connecting rod 121, the second connecting rod 122, the first connecting rod 123, and the second connecting rod 124), this does not affect the fact that the second transmission component 12 is an integrally formed structure; that is, the first connecting rod 121, the second connecting rod 122, the first connecting rod 123, and the second connecting rod 124 may be integrally formed.

[0192] Exemplarily, the first connecting rod 121 may include a first end 1211, a second end 1212, and a first engaging portion 1213 located between the first end 1211 and the second end 1212. The first engaging portion 1213 may be a groove, and the opening of the groove may be oriented towards the second connecting rod 122. Exemplarily, the first engaging portion 1213 may be an arc-shaped groove. In other embodiments, the first engaging portion 1213 may also be an elongated groove. The opening of the angle between the length extension direction of the first engaging portion 1213 and the thickness direction of the base 30 (i.e., the Z-axis direction in this embodiment) may be oriented towards the second direction.

[0193] For example, the first link 121 may further include a first sliding protrusion 1214 and a second sliding protrusion 1215. The first sliding protrusion 1214 may be located between the first end 1211 and the second end 1212, and may be fixedly connected to the surface of the first link 121 facing away from the second link 122. The second sliding protrusion 1215 may be located at the second end 1212 of the first link 121, and may be fixedly connected to the surface of the first link 121 facing away from the second link 122. The first sliding protrusion 1214 and the second sliding protrusion 1215 may be spaced apart. The first sliding protrusion 1214 may be located at the midpoint of the first link 121, or the distance between the first sliding protrusion 1214 and the midpoint of the first link 121 may be less than or equal to 25% of the length of the first link 121.

[0194] For example, the second connecting rod 122 may include a third end 1221, a fourth end 1222, and a second engaging portion 1223 located between the third end 1221 and the fourth end 1222. The second engaging portion 1223 may be a groove, and the opening of the groove may be oriented towards the first connecting rod 121. For example, the second engaging portion 1223 may be an arc-shaped groove. In other embodiments, the second engaging portion 1223 may also be an elongated groove. The opening of the angle between the length extension direction of the second engaging portion 1223 and the thickness direction of the base 30 (i.e., the Z-axis direction in this embodiment) may be oriented towards the second direction.

[0195] For example, the second link 122 may further include a third sliding protrusion 1224 and a fourth sliding protrusion 1225. The third sliding protrusion 1224 may be located between the third end 1221 and the fourth end 1222, and may be fixedly connected to the surface of the second link 122 facing away from the first link 121. The fourth sliding protrusion 1225 may be located at the fourth end 1222 of the second link 122, and may be fixedly connected to the surface of the second link 122 facing away from the first link 121. The third sliding protrusion 1224 and the fourth sliding protrusion 1225 may be spaced apart.

[0196] For example, the first end 1211 of the first link 121 may be opposite to and spaced apart from the third end 1221 of the second link 122. The second end 1212 of the first link 121 may be opposite to and spaced apart from the fourth end 1222 of the second link 122. The first connecting rod 123 may be fixedly connected to the first end 1211 of the first link 121 and the third end 1221 of the second link 122. The second connecting rod 124 may be positioned closer to the second end 1212 than the first end 1211 of the first link 121.

[0197] Figure 26 yes Figure 6 The diagram shows a partial assembly structure of the lifting device 310 in some embodiments. Figure 27 yes Figure 6 The diagram shows a partial assembly structure of the lifting device 310 in some embodiments. Figure 28 yes Figure 27 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along line HH. It should be noted that, for ease of understanding, Figure 26 The structure of base 30 is omitted.

[0198] like Figures 26 to 28As shown, exemplarily, the second transmission member 12 may be located inside the base 30. The first link 121 of the second transmission member 12 may be disposed closer to the first sidewall 31a than the second sidewall 31b of the base 30. The second link 122 of the second transmission member 12 may be disposed closer to the second sidewall 31b than the first sidewall 31a of the base 30.

[0199] Exemplarily, the first transmission member 11, the buffer mechanism 20, and the drive member 28 can all be located between the first link 121 and the second link 122 of the second transmission member 12. Specifically, the first link 121 of the second transmission member 12 can be located on the side of the first mounting portion 1121 of the first transmission member 11 facing away from the fourth mounting portion 1124. The second link 122 of the second transmission member 12 can be located on the side of the fourth mounting portion 1124 of the first transmission member 11 facing away from the first mounting portion 1121. Furthermore, the first transmission member 11, the buffer mechanism 20, and the drive member 28 can all be positioned closer to the second end 1212 of the second transmission member 12 than the first end 1211.

[0200] For example, the first connecting rod 121 of the second transmission member 12 may have a clearance hole 1216. The clearance hole 1216 may be located at the second end 1212 of the first connecting rod 121. The third rotating shaft 273 of the buffer mechanism 20 may pass through the clearance hole 1216 of the second transmission member 12. At this time, the third rotating shaft 273 may pass through the fourth through hole 262a of the second rod 26, the clearance hole 1216 of the second transmission member 12, and the small hole 313 of the base 30 in sequence (see reference). Figure 15a (As shown). In other embodiments, the first link 121 of the second transmission member 12 may not have the clearance hole 1216. The third shaft 273 may be located between the first link 121 and the second link 122 of the second transmission member 12.

[0201] For example, the first transmission member 11 may also have a first movable part 1151 ( Figure 19a and Figure 19b The structure of the first movable part 1151 is also illustrated. The first movable part 1151 can be a movable protrusion. The first movable part 1151 can be spaced apart from the first end 111 and the second end 112 of the first transmission member 11. The first movable part 1151 is also spaced apart from the central axis of the first mounting hole 1121a. The first movable part 1151 can be positioned toward the first connecting rod 121 of the second transmission member 12. The first movable part 1151 of the first transmission member 11 can be rotatably connected to the first mating movable part 1213 of the second transmission member 12, and there is a sliding connection between them. That is, the first connecting rod 121 of the second transmission member 12 can be movably connected to the first transmission member 11 under the combined action of the first mating movable part 1213 and the first movable part 1151.

[0202] For example, the first transmission member 11 may also have a second movable part 1152. Figure 19a and Figure 19b The structure of the second movable part 1152 is also illustrated. The second movable part 1152 can also be a movable protrusion. The second movable part 1152 can be disposed opposite to the first movable part 1151. The second movable part 1152 can also be disposed spaced apart from the first end 111 and the second end 112 of the first transmission member 11. The second movable part 1152 is also disposed spaced apart from the central axis of the first mounting hole 1121a. The second movable part 1152 can be disposed toward the second connecting rod 122 of the second transmission member 12. The second movable part 1152 can be rotatably connected to the second mating movable part 1223 of the second transmission member 12, and has a sliding connection relationship with the second mating movable part 1223. That is, the second connecting rod 122 of the second transmission member 12 can be movably connected to the first transmission member 11 under the combined action of the second mating movable part 1223 and the second movable part 1152.

[0203] Figure 29 yes Figure 27 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along point II.

[0204] like Figures 27 to 29 As shown, the base 30 may also have a first groove 321 ( Figure 14a and Figure 14b The structure of the first groove 321 is also illustrated. The first groove 321 can connect to the mounting space of the base 30. Exemplarily, the opening of the first groove 321 can face the mounting space of the base 30. The first groove 321 can be formed in the second part 32 of the base 30. The first groove 321 can be an arc-shaped groove. The first groove 321 of the base 30 can be rotatably connected to the first sliding protrusion 1214 of the first connecting rod 121 of the second transmission member 12, and has a sliding connection relationship with the first sliding protrusion 1214.

[0205] For example, the base 30 may also have a second groove 311 ( Figure 14a and Figure 14b The structure of the second slide groove 311 is also illustrated. The second slide groove 311 can connect to the mounting space of the base 30. Exemplarily, the second slide groove 311 can penetrate through the first sidewall 31a of the base 30. The second slide groove 311 can connect to the first space 30a of the base 30. The second slide groove 311 of the base 30 can rotatably connect to the second sliding protrusion 1215 of the first connecting rod 121 of the second transmission member 12, and there is a sliding connection between the second slide groove 311 and the second sliding protrusion 1215.

[0206] For example, the base 30 may also have a third groove 322. Figure 14a and Figure 14bThe structure of the third slide groove 322 is also illustrated. The third slide groove 322 can connect to the mounting space of the base 30. Exemplarily, the opening of the third slide groove 322 can face the mounting space of the base 30. The third slide groove 322 can be formed in the second part 32 of the base. The third slide groove 322 can be opposite to and spaced apart from the first slide groove 321. The third slide groove 322 of the base 30 can be rotatably connected to the third sliding protrusion 1224 of the second connecting rod 122 of the second transmission member 12, and there is a sliding connection between the third slide groove 322 and the third sliding protrusion 1224.

[0207] For example, the base 30 may also have a fourth groove 312 ( Figure 14a and Figure 14b The structure of the fourth slide groove 312 is also illustrated. The fourth slide groove 312 can connect to the mounting space of the base 30. Exemplarily, the fourth slide groove 312 can penetrate the second sidewall 31b of the base 30. The fourth slide groove 312 can connect to the first space 30a of the base 30. The fourth slide groove 312 can be opposite to and spaced apart from the second slide groove 311. The fourth slide groove 312 of the base 30 can be rotatably connected to the fourth sliding protrusion 1225 of the second connecting rod 122 of the second transmission member 12, and there is a sliding connection between the fourth slide groove 312 and the fourth sliding protrusion 1225.

[0208] Figure 30 yes Figure 5 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 when it is in the first state, cut along point JJ. Figure 31 yes Figure 5 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 when it is in the first state, cut along point KK.

[0209] like Figure 27 , Figure 30 as well as Figure 31 As shown, when the lifting device 310 is in the first state, the included angle between the second transmission member 12 and the first plane can be the fifth included angle γ1 (e.g., Figure 30 (As shown). In this embodiment, the fifth included angle γ1 can be equal to 0°, that is, when the lifting device 310 is in the first state, the second transmission member 12 can be parallel to the first plane. The distance between the first end 1211 of the first connecting rod 121 of the second transmission member 12 and the bottom surface of the base 30 can be the first distance. The distance between the third end 1221 of the second connecting rod 122 of the second transmission member 12 and the bottom surface of the base 30 can be equal to the first distance. The distance between the first end 111 of the first transmission member 11 and the bottom surface of the base 30 can be equal to the first distance. In this embodiment, the bottom surface of the base 30 can be the surface of the first sidewall 31a and the second sidewall 31b of the base 30 facing away from the top plate 31c.

[0210] For example, the center of curvature O1 of the first mating movable part 1213 of the second transmission member 12 can be located on the side of the first mating movable part 1213 facing away from the first end 111 of the first transmission member 11. The center of curvature O1 of the first mating movable part 1213 can also be located on the side of the first mating movable part 1213 facing away from the first end 1211 of the first connecting rod 121 of the second transmission member 12 (e.g., Figure 30 (As shown).

[0211] For example, the curvature center O2 of the first groove 321 of the base 30 can be located on one side of the first groove 321 toward the first end 1211 of the first connecting rod 121 of the second transmission member 12 (e.g. Figure 31 (As shown).

[0212] Figure 32 yes Figure 27 The diagram shown is a schematic of the structure in its intermediate state. Figure 33 yes Figure 30 The diagram shown is a schematic of the structure in its intermediate state. Figure 34 yes Figure 31 The diagram shown is a schematic of the structure in its intermediate state.

[0213] like Figures 32 to 34 As shown, the camera decorative assembly 300 can also have an intermediate state, that is, the lifting device 310 can also have an intermediate state. The intermediate state can be a state between the first state and the second state. When the camera decorative assembly 300 switches from the first state to the second state, the camera decorative piece 320 can rise relative to the back cover 202 under the action of the lifting device 310, so that the camera decorative assembly 300 can switch from the first state to the intermediate state. Then, the camera decorative piece 320 can continue to rise relative to the back cover 202 under the action of the lifting device 310, so that the camera decorative assembly 300 can switch from the intermediate state to the second state. When the camera decorative assembly 300 switches from the second state to the first state, the camera decorative piece 320 can descend relative to the back cover 202 under the action of the lifting device 310, so that the camera decorative assembly 300 can switch from the second state to the intermediate state. Then, the camera decorative piece 320 can continue to descend relative to the back cover 202 under the action of the lifting device 310, so that the camera decorative assembly 300 can switch from the intermediate state to the first state.

[0214] For example, when the lifting device 310 is in the intermediate state, the included angle between the second transmission member 12 and the first plane can be a sixth included angle γ2 (e.g., Figure 33(As shown). The angle of the sixth included angle γ2 can be greater than the angle of the fifth included angle γ1. Specifically, in the Z-axis direction, the opening of the sixth included angle γ2 can face the positive direction of the Z-axis, i.e., the first direction. The distance between the first end 1211 of the first connecting rod 121 of the second transmission member 12 and the bottom surface of the base 30 can be greater than the first distance. The distance between the third end 1221 of the second connecting rod 122 of the second transmission member 12 and the bottom surface of the base 30 can be equal to the distance between the first end 1211 of the first connecting rod 121 of the second transmission member 12 and the bottom surface of the base 30. The distance between the first end 111 of the first transmission member 11 and the bottom surface of the base 30 can be equal to the distance between the first end 1211 of the first connecting rod 121 of the second transmission member 12 and the bottom surface of the base 30.

[0215] Figure 35 yes Figure 27 The diagram shown is a schematic of the structure in its second state. Figure 36 yes Figure 30 The diagram shown is a schematic of the structure in its second state. Figure 37 yes Figure 31 The diagram shown is a schematic of the structure in its second state.

[0216] like Figures 35 to 37 As shown, when the lifting device 310 is in the second state, the included angle between the second transmission member 12 and the first plane can be the seventh included angle γ3 (e.g., Figure 36 (As shown). The angle of the seventh included angle γ3 can be greater than the angle of the sixth included angle γ2. Specifically, in the Z-axis direction, the opening of the seventh included angle γ3 can also face the positive direction of the Z-axis, i.e., the first direction. The distance between the first end 1211 of the first connecting rod 121 of the second transmission member 12 and the bottom surface of the base 30 can be the second distance. The distance between the third end 1221 of the second transmission member 12 and the bottom surface of the base 30 can be equal to the second distance. The distance between the first end 111 of the first transmission member 11 and the bottom surface of the base 30 can be equal to the second distance.

[0217] Please combine them together Figure 27 , Figures 30 to 37 As shown, during the process of the lifting device 310 switching from the first state to the intermediate state and then from the intermediate state to the second state, the first transmission member 11 can rotate relative to the base 30 along the first rotation direction a. The angle between the second transmission member 12 and the first plane can gradually increase. The first movable part 1151 of the first transmission member 11 can slide relative to the first engaging movable part 1213 of the first connecting rod 121 of the second transmission member 12 along the direction close to the first end 1211 of the first connecting rod 121, and drive the second transmission member 12 to move relative to the base 30 (please refer to...). Figure 30 , Figure 33 as well as Figure 36 (As shown).

[0218] In this configuration, the first end 1211 of the first connecting rod 121 of the second transmission member 12 can move relative to the base 30 along a first direction. The first sliding protrusion 1214 of the first connecting rod 121 can move relative to the first groove 321 of the base 30 along a direction away from the first portion 31 of the base 30 (please refer to...). Figure 31 , Figure 34 as well as Figure 37 (As shown). The second sliding protrusion 1215 of the first link 121 can move relative to the second slide groove 311 of the base 30 first along a third direction, and then along a fourth direction (please refer to...). Figure 31 , Figure 34 as well as Figure 37 (As shown). The third and fourth directions can be opposite directions. For example, the third direction can be perpendicular to the first direction. In this embodiment, the third direction can be the positive direction of the X-axis. The fourth direction can be the negative direction of the X-axis.

[0219] For example, during the process of switching the lifting device 310 from the second state to the intermediate state and then from the intermediate state to the first state, the first transmission member 11 can rotate relative to the base 30 along the second rotation direction b. The angle between the second transmission member 12 and the first plane can gradually decrease. The first movable part 1151 of the first transmission member 11 can slide relative to the first engaging movable part 1213 of the first connecting rod 121 of the second transmission member 12 along a direction close to the second end 1212 of the first connecting rod 121, thereby driving the second transmission member 12 to move relative to the base 30. (Please refer to...) Figure 30 , Figure 33 as well as Figure 36 (As shown).

[0220] The first end 1211 of the first connecting rod 121 of the second transmission member 12 can move relative to the base 30 in a second direction. The first sliding protrusion 1214 of the first connecting rod 121 can move relative to the first groove 321 of the base 30 in a direction close to the first portion 31 of the base 30 (please refer to...). Figure 31 , Figure 34 as well as Figure 37 (As shown). The second sliding protrusion 1215 of the first link 121 can move relative to the second slide groove 311 of the base 30 first along a third direction, and then along a fourth direction (please refer to...). Figure 31 , Figure 34 as well as Figure 37 (As shown).

[0221] For example, the relative motion relationship between the second engaging movable part 1223, the third sliding protrusion 1224, and the fourth sliding protrusion 1225 of the second connecting rod 122 of the second transmission member 12 and the second movable part 1152, the third sliding groove 322, and the fourth sliding groove 312 can be the same as the relative motion relationship between the first engaging movable part 1213, the first sliding protrusion 1214, and the second sliding protrusion 1215 of the first connecting rod 121 of the second transmission member 12 and the first movable part 1151, the first sliding groove 321, and the second sliding groove 311, and will not be described again here.

[0222] In some embodiments, the first link 121 of the second transmission member 12 may not include the first sliding protrusion 1214, the base may not include the first slide groove 321, and / or, the first link 121 of the second transmission member 12 may not include the second sliding protrusion 1215, and the base may not include the second slide groove 311. The second link 122 of the second transmission member 12 may not include the third sliding protrusion 1224, the base may not include the third slide groove 322, and / or, the second link 122 of the second transmission member 12 may not include the fourth sliding protrusion 1225, and the base may not include the fourth slide groove 312.

[0223] In some embodiments, the second transmission member 12 may not include the first connecting rod 123 and / or the second connecting rod 124.

[0224] In some embodiments, the second transmission member 12 may not include the second connecting rod 122.

[0225] Figure 38a yes Figure 6 The mounting component 40 shown is a structural schematic diagram in some embodiments. Figure 38b yes Figure 38a The structural schematic diagram of the mounting component 40 shown from another perspective.

[0226] like Figure 38a and Figure 38b As shown, the mounting member 40 can be generally annular. The mounting member 40 may include a main body 41, a first mounting protrusion 42, a second mounting protrusion 43, a third mounting protrusion 44, and a fourth mounting protrusion 45. The first mounting protrusion 42, the second mounting protrusion 43, the third mounting protrusion 44, and the fourth mounting protrusion 45 can all be located on the same side of the main body 41 and are all fixedly connected to the main body 41. The first mounting protrusion 42, the second mounting protrusion 43, the third mounting protrusion 44, and the fourth mounting protrusion 45 can be spaced apart from each other. Specifically, the first mounting protrusion 42 and the second mounting protrusion 43 can be located on the same side of the third mounting protrusion 44 and the fourth mounting protrusion 45. The first mounting protrusion 42 can be positioned opposite to the third mounting protrusion 44. The second mounting protrusion 43 can be positioned opposite to the fourth mounting protrusion 45.

[0227] For example, the first mounting protrusion 42 may be provided with a first movable groove 42a. The third mounting protrusion 44 may be provided with a second movable groove 44a. The opening of the first movable groove 42a may be opposite to the opening of the second movable groove 44a. The length extension directions of both the first movable groove 42a and the second movable groove 44a may be parallel to the third direction.

[0228] Figure 39 yes Figure 6 The diagram shows a partial assembly structure of the lifting device 310 in some embodiments. Figure 40 yes Figure 39 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along LL. Figure 41 yes Figure 39 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 cut along the mm line.

[0229] like Figures 39 to 41 As shown, the first end 111 of the first transmission member 11 may have a first movable protrusion 1111 and a second movable protrusion 1112 spaced apart. Figure 19a and Figure 19b The structure of the first movable protrusion 1111 and the second movable protrusion 1112 is also illustrated. The first movable protrusion 1111 and the second movable protrusion 1112 can be rotatably connected to the first movable groove 42a and the second movable groove 44a, respectively, and have a sliding connection relationship with the first movable groove 42a and the second movable groove 44a, respectively. The second end 1212 of the first connecting rod 121 of the second transmission member 12 can be rotatably connected to the second mounting protrusion 43 of the mounting member 40. For example, the second mounting protrusion 43 of the mounting member 40 can have a rotating hole 43a. The second end 1212 of the first connecting rod 121 of the second transmission member 12 can have a mating rotating hole 1217. The mating rotating hole 1217 can be arranged directly opposite the rotating hole 43a. The lifting device 310 may also include a rotating shaft 80. The rotating shaft 80 can be sequentially inserted into the rotating hole 43a and the mating rotating hole 1217. At this time, the first connecting rod 121 of the second transmission member 12 can rotate relative to the base 30 with the central axis of the rotating hole 1217 as the rotation center, either in the first rotation direction a or in the second rotation direction b.

[0230] For example, the curvature center O1 of the second mating movable part 1213 of the second transmission member 12 can be located on the side of the second mating movable part 1213 facing away from the mounting member 40 (see reference). Figure 30 (As shown).

[0231] For example, the third end 1221 of the second link 122 of the second transmission member 12 can be rotatably connected to the fourth mounting protrusion 45 of the mounting member 40. The way in which the third end 1221 of the second link 122 is rotatably connected to the fourth mounting protrusion 45 of the mounting member 40 can be the same as the way in which the first end 1211 of the first link 121 is rotatably connected to the second mounting protrusion 43 of the mounting member 40, and will not be described again here.

[0232] Figure 42 yes Figure 5 The diagram shows a partial cross-sectional view of one embodiment of the lifting device 310 when it is in the first state, cut along NN. Figure 43 yes Figure 42 The diagram shown is a schematic of the structure in its intermediate state. Figure 44 yes Figure 42 The diagram shown is a schematic of the structure in its second state.

[0233] like Figures 42 to 44 As shown, when the lifting device 310 is in the first state (e.g.) Figure 42 As shown, the mounting member 40 can be parallel to the base 30. The distance between the mounting member 40 and the base 30 can be a first gap. The first gap can be greater than or equal to 0. Exemplarily, the first gap can be the distance between the bottom surface of the mounting member 40 and the bottom surface of the base 30 in the Z-axis direction. In this embodiment, the bottom surface of the mounting member 40 can be the surface of the main body 41 of the mounting member 40 facing the first mounting protrusion 42. When the lifting device 310 is in the intermediate state, the mounting member 40 can be parallel to the base 30. The distance between the mounting member 40 and the base 30 can be greater than the first gap. When the lifting device 310 is in the second state, the mounting member 40 can be parallel to the base 30. The distance between the mounting member 40 and the base 30 can be a second gap. The second gap can be greater than the first gap.

[0234] For example, during the process of switching the lifting device 310 from a first state to an intermediate state and then from the intermediate state to a second state, the first transmission member 11 can rotate relative to the base 30 along a first rotation direction a. The first end 111 of the first transmission member 11 can generate a displacement relative to the base 30 along the first direction. The second transmission member 12 can move relative to the base 30 under the action of the first transmission member 11 and rotate relative to the mounting member 40 along the first rotation direction a. The first end 1211 of the first connecting rod 121 and the third end 1221 of the second connecting rod 122 of the second transmission member 12 can both generate a displacement relative to the base 30 along the first direction, and the two displacements are the same. At this time, the mounting member 40 can generate a displacement relative to the base 30 along the first direction under the combined action of the first transmission member 11 and the second transmission member 12.

[0235] During the transition from the first state to the intermediate state of the lifting device 310, the first movable protrusion 1111 of the first end 111 of the first transmission member 11 can slide relative to the first movable groove 42a of the mounting member 40 in a fourth direction. At this time, the first end 111 of the first transmission member 11 can generate a first displacement relative to the base 30 in a fourth direction. The mounting member 40 can generate a second displacement relative to the first end 111 of the first transmission member 11 in a third direction. The first displacement can be equal to the second displacement. During the transition from the intermediate state to the second state of the lifting device 310, the first movable protrusion 1111 of the first end 111 of the first transmission member 11 can slide relative to the first movable groove 42a of the mounting member 40 in a third direction. At this time, the first end 111 of the first transmission member 11 can generate a third displacement relative to the base 30 in a third direction. The mounting member 40 can generate a fourth displacement relative to the first end 111 of the first transmission member 11 in a fourth direction. The third displacement can be equal to the fourth displacement. In this way, the first displacement can cancel out the second displacement, and the third displacement can cancel out the fourth displacement, so that the mounting member 40 can only generate displacement in the first direction relative to the base 30 during the process of the lifting device 310 switching from the first state to the intermediate state and from the intermediate state to the second state. That is, the mounting member 40 can move relative to the base 30 in the first direction under the combined action of the first transmission member 11 and the second transmission member 12.

[0236] For example, during the process of switching the lifting device 310 from the second state to the intermediate state and then from the intermediate state to the first state, the first transmission member 11 can rotate relative to the base 30 along the second rotation direction b. The first end 111 of the first transmission member 11 can generate a displacement relative to the base 30 along the second direction. The second transmission member 12 can move relative to the base 30 under the action of the first transmission member 11 and rotate relative to the mounting member 40 along the second rotation direction b. The first end 1211 of the first connecting rod 121 and the third end 1221 of the second connecting rod 122 of the second transmission member 12 can both generate a displacement relative to the base 30 along the second direction, and the two displacements are the same. At this time, the mounting member 40 can generate a displacement relative to the base 30 along the second direction under the combined action of the first transmission member 11 and the second transmission member 12.

[0237] During the transition from the second state to the intermediate state of the lifting device 310, the first movable protrusion 1111 of the first end 111 of the first transmission member 11 can slide relative to the first movable groove 42a of the mounting member 40 in the fourth direction. At this time, the first end 111 of the first transmission member 11 can generate a fifth displacement relative to the base 30 in the fourth direction. The mounting member 40 can generate a sixth displacement relative to the first end 111 of the first transmission member 11 in the third direction. The fifth displacement can be equal to the sixth displacement. During the transition from the intermediate state to the first state of the lifting device 310, the first movable protrusion 1111 of the first end 111 of the first transmission member 11 can slide relative to the first movable groove 42a of the mounting member 40 in the third direction. At this time, the first end 111 of the first transmission member 11 can generate a seventh displacement relative to the base 30 in the third direction. The mounting member 40 can generate an eighth displacement relative to the first end 111 of the first transmission member 11 in the fourth direction. The seventh displacement can be equal to the eighth displacement. In this way, the fifth displacement can cancel out the sixth displacement, and the seventh displacement can cancel out the eighth displacement, so that the mounting member 40 can only generate displacement in the second direction relative to the base 30 during the process of the lifting device 310 switching from the second state to the intermediate state and from the intermediate state to the first state. That is, the mounting member 40 can move relative to the base 30 in the second direction under the combined action of the first transmission member 11 and the second transmission member 12.

[0238] For example, the relative movement relationship between the second movable protrusion 1112 of the first end 111 of the first transmission member 11 and the second movable groove 44a of the mounting member 40 can be the same as the relative movement relationship between the first movable protrusion 1111 and the first movable groove 42a, and will not be described again here.

[0239] It is understandable that, compared to general lifting devices that use gear and worm gear transmissions and utilize the guide rail between the base and the mounting component to convert the circumferential rotation of the base into the vertical lifting motion of the mounting component, thus achieving the lifting of the mounting component, this results in a larger number of lifting device components, higher manufacturing costs, and a smaller lifting stroke. Furthermore, the use of a higher-pair mechanism in the lifting device leads to lower transmission efficiency, higher frictional losses, and higher power consumption during operation. In contrast, in this embodiment, the base 30 and the mounting component 40 of the lifting device 310 are connected by a transmission mechanism 10, which is a linkage mechanism. That is, the base 30 and the mounting component 40 are connected by 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 mounting component 40. Simultaneously, the components of the transmission mechanism 10 have simple structures and are easy to manufacture, reducing manufacturing costs and simplifying the manufacturing process.

[0240] Secondly, in this embodiment, the first transmission member 11 may have a first movable protrusion 1111, and the mounting member 40 may have a first movable groove 42a. The first movable protrusion 1111 of the first transmission member 11 can cooperate with the first movable groove 42a of the mounting member 40, so that the mounting member 40 can only generate displacement in the first direction or the second direction relative to the base 30. That is, the mounting member 40 in this embodiment can achieve linear lifting and lowering relative to the base 30. In this way, the mounting member 40 only moves in the vertical direction (i.e., the Z-axis direction in this embodiment) relative to the base 30, and does not move in the horizontal direction (i.e., the X-axis direction and the Y-axis direction in this embodiment), thereby avoiding the mounting member 40 from bumping or squeezing the base 30 or other components of the lifting device 310, and thus avoiding damage to the lifting device 310 by the mounting member 40.

[0241] Furthermore, in this embodiment, both the first connecting rod 123 and the second connecting rod 124 of the second transmission member 12 can be fixed between the first connecting rod 121 and the second connecting rod 122. This has two advantages: firstly, the first connecting rod 123 and the second connecting rod 124 make the structure of the second transmission member 12 more stable and improve its structural strength, thus preventing damage from external forces; secondly, the first connecting rod 121 and the second connecting rod 122 can move synchronously under the action of the first connecting rod 123 and the second connecting rod 124. During the operation 310 of the lifting device, the first end 1211 of the first connecting rod 121 and the third end 1221 of the second connecting rod 122 can move synchronously, allowing the second mounting protrusion 43 and the fourth mounting protrusion 45 of the mounting member to move synchronously. Simultaneously, the first mounting protrusion 42 and the third mounting protrusion 44 of the mounting member 40 can also move synchronously with the second mounting protrusion 43 and the fourth mounting protrusion 45 under the action of the first transmission member 11. At this time, the two sides of the mounting part 40 can move synchronously relative to the base 30, that is, the mounting part 40 will not tilt during the movement, thus making the movement of the mounting part 40 relatively stable.

[0242] Furthermore, in this embodiment, the main body 22a of the torsion spring 22 is in a compressed state in its axial direction (i.e., the Y-axis direction in this embodiment). At this time, the first protrusion 33 of the base 30 can abut against the first branch 2411 of the connector 24 under the action of the main body 22a of the torsion spring 22 and the first sleeve 23, so that there can be a large static friction between the first protrusion 33 of the base 30 and the first branch 2411 of the connector 24, that is, there can be a large static friction between the connector 24 and the base 30. In this way, no matter where the mounting member 40 is, the first transmission member 11 and the base 30 can remain relatively stationary. In other words, when the lifting device 310 is in any state, the mounting member 40 can be suspended without shaking.

[0243] Furthermore, in this embodiment, the torsion spring 22 is in a compressed state in its radial direction, meaning that the first extension 22b and the second extension 22c of the torsion spring 22 tend to move in opposite directions and open relative to each other. Thus, when the mounting member 40 is subjected to an external force and tends to move along the second direction, the first extension 22b of the torsion spring 22 can abut against the bottom surface 2421a of the first mounting groove 2421 of the connector 24, and the second extension 22c of the torsion spring 22 can abut against the wall of the second mounting groove 113 of the first transmission member 11. This prevents relative rotation between the connector 24 and the first transmission member 11, allowing the mounting member 40 to remain stationary relative to the base 30. In other words, the torsion spring 22 in this embodiment provides a buffering effect through the lifting device 310, ensuring that the mounting member 40 remains stationary relative to the base 30 even when subjected to external forces, thus improving the user experience.

[0244] Furthermore, unlike typical lifting devices where the second transmission component is only movably connected to the first transmission component, and the first transmission component drives the second transmission component to move relative to the base, allowing the mounting component to rise or fall relative to the base, the second transmission component is only movably connected to the first transmission component. This makes the movement of the second transmission component difficult to control during the operation of the lifting device, reducing the movement accuracy of the lifting device. In this embodiment, the second transmission component 12 of the lifting device 310 is also movably connected to the base 30. The second transmission component 12 may also include a first sliding protrusion 1214 and a second sliding protrusion 1215, and the base 30 also has a first sliding groove 321 and a second sliding groove 311. The first sliding protrusion 1214 and the second sliding protrusion 1215 can be movably connected to the first sliding groove 321 and the second sliding groove 311, respectively. Thus, during the operation of the lifting device 310, the second transmission member 12, under the cooperative action of the first sliding protrusion 1214, the second sliding protrusion 1215, the first sliding groove 321, and the second sliding groove 311, can rotate relative to the base 30 around the central axis of the rotating hole 43a, along either the first rotation direction a or the second rotation direction b. In other words, the second transmission member 12, under the cooperative action of the first sliding protrusion 1214, the second sliding protrusion 1215, the first sliding groove 321, and the second sliding groove 311, can perform more stable movement relative to the base 30, thereby improving the motion accuracy of the lifting device 310.

[0245] Figure 45 yes Figure 6 The diagram shows the assembly structure of the lifting device 310 in some embodiments. Figure 46 yes Figure 5 The diagram shows a cross-sectional view of one embodiment of the lifting device 310 cut along point KK. Figure 47 yes Figure 45The diagram shows a cross-sectional view of one embodiment of the lifting device 310 cut along point OO. Figure 48 yes Figure 45 The diagram shows a cross-sectional structure of one embodiment of the lifting device 310 when it is in the second state, cut along PP.

[0246] like Figures 45 to 48 As shown, the electrical connector 50 can be arranged around a portion of the base 30 and fixedly connected to the base 30. The electrical connector 50 can be a circuit board, such as a flexible circuit board, a rigid circuit board, or a rigid-flex circuit board. The electrical connector 50 can be electrically connected between the drive unit 28 and the motherboard of the electronic device 1000, that is, the drive unit 28 can be electrically connected to the motherboard of the electronic device 1000 (not shown) through the electrical connector 50. The motherboard can input a first electrical signal to the drive unit body 28b through the electrical connector 50, so that the drive unit 28 can drive the mounting member 40 to produce a displacement in a first direction relative to the base 30 through the transmission mechanism 10. The motherboard can input a second electrical signal to the drive unit body 28b through the electrical connector 50, so that the drive unit 28 can drive the mounting member 40 to produce a displacement in a second direction relative to the base 30 through the transmission mechanism 10.

[0247] For example, the sensor 60 can be fixed to the base 30 and electrically connected to the electrical connector 50. The sensor 60 can be a Hall sensor. The base 30 may also have a third mounting slot 323. Figure 14a The structure of the third mounting slot 323 is also illustrated. The opening of the third mounting slot 323 can face away from the mounting space of the base 30. The third mounting slot 323 can be formed in the second part 32 of the base 30. The sensor 60 can be mounted in the third mounting slot 323.

[0248] For example, the magnetic element 70 can be fixed to the surface of the first connecting rod 121 of the second transmission member 12 facing away from the second connecting rod 122. The magnetic element 70 can be positioned close to the first sliding protrusion 1214 relative to the first end 1211 and the second end 1212 of the first connecting rod 121. The second transmission rod may also have a fourth mounting groove 1218 (see reference). Figure 25a (As shown). A fourth mounting groove 1218 may be formed in the first connecting rod 121. The opening of the fourth mounting groove 1218 may be positioned away from the second connecting rod 122. The fourth mounting groove 1218 may be spaced apart from the first end 1211 and the second end 1212 of the second transmission member 12. The fourth mounting groove 1218 may be positioned close to the first sliding protrusion 1214 relative to the first end 1211 and the second end 1212 of the first connecting rod 121. A magnetic member 70 may be embedded in the fourth mounting groove 1218.

[0249] For example, the sensor 60 can be used to detect the change in the magnetic field of the magnetic component 70 when the first link 121 moves relative to the base 30, so as to detect the relative positional relationship between the first link 121 and the base 30, thereby detecting the distance that the mounting component 40 moves relative to the base 30.

[0250] It is understood that the lifting device 310 in this embodiment also includes a magnetic component 70 and a sensor 60. The magnetic component 70 can be fixed to the first connecting rod 121, and the sensor 60 can be fixed to the base 30. In this way, the lifting device 310 can detect the position of the mounting component 40 relative to the base 30 through the cooperation between the magnetic component 70 and the sensor 60, which helps to improve the control accuracy and motion accuracy of the lifting device 310, thereby improving the user experience.

[0251] Secondly, compared to lifting devices that mount magnetic components to the mounting component, when the relative distance between the mounting component and the base is large, the magnetic component may exceed the sensor's detection range, thereby reducing the sensor's accuracy in detecting the mounting component's position, or even preventing the sensor from detecting the mounting component's position. In this embodiment, the lifting device 310 fixes the magnetic component 70 to the first connecting rod 121, with the magnetic component 70 positioned closer to the first sliding protrusion 1214 than the first end 1211 and second end 1212 of the first connecting rod 121. When the lifting device 310 switches between the first and second states, the displacement of the magnetic component 70 relative to the base 30 is less than the displacement of the first end 1211 of the first connecting rod 121 relative to the base 30, but greater than the displacement of the second end 1212 of the first connecting rod 121 relative to the base 30. That is, the displacement of the magnetic component 70 relative to the base 30 is more moderate. In this way, during the operation of the lifting device 310, the movement of the magnetic component 70 will not exceed the detection range of the sensor 60, and it is easy for the sensor 60 to detect it, which helps to improve the detection accuracy of the sensor 60, thereby improving the control accuracy of the lifting device 310.

[0252] In other embodiments, the magnetic element 70 may also be mounted on the first transmission member 11. The magnetic element 70 may be disposed close to the first end 111 relative to the second end 112 of the first transmission member 11.

[0253] Figure 49 yes Figure 4a The diagram shows a cross-sectional structure of one embodiment in which the camera decorative component 300 is cut along QQ when it is in the first state. Figure 50 yes Figure 49 The diagram shown is a schematic of the structure in its second state. Figure 51 yes Figure 49 The diagram shown is a schematic of the structure in its third state.

[0254] like Figures 49 to 51 As shown, the camera decorative component 320 can be fitted onto the mounting component 40. When the camera decorative component 300 switches between the first state and the second state, the mounting component 40 can drive the camera decorative component 320 to move relative to the base 30 along the first or second direction, thereby realizing the movement of the camera decorative component 320 relative to the base 30 along the thickness direction of the electronic device 1000.

[0255] For example, the fourth movable end 262 of the second rod 26 of the buffer mechanism 20 may also be provided with a stop protrusion 263. The base 30 may also have a baffle 35. Figure 14b The structure of the baffle 35 is also illustrated. The baffle 35 can be located in the first space 30a and fixedly connected to the top plate 31c. The stop protrusion 263 and the baffle 35 can be arranged along the second rotation direction b. Specifically, the stop protrusion 263 and the baffle 35 can be spaced apart along the second rotation direction b when the camera decoration assembly 300 is in the first state and the second state. When the camera decoration assembly 300 switches from the first state to the second state, the second rod 26 can rotate relative to the base 30 along the second rotation direction b. At this time, the stop protrusion 263 of the second rod 26 can gradually approach the baffle 35.

[0256] Exemplarily, the camera decoration assembly 300 may also have a third state. When the camera decoration assembly 300 is in the second state, the drive member 28 of the lifting device 310 may continue to drive the second rod 26 to rotate relative to the base 30 in the second rotation direction b until the stop protrusion 263 of the second rod 26 contacts / aggregates with the baffle 35, thereby switching the camera decoration assembly 300 from the second state to the third state. During the process of switching the camera decoration assembly 300 from the second state to the third state, the connector 24 may remain stationary relative to the base 30, that is, the mounting member 40 may remain stationary relative to the base 30. At this time, the first rod 25 may rotate relative to the second rod 26 in the first rotation direction a under the combined action of the second rod 26 and the connector 24, and also rotate relative to the connector 24 in the first rotation direction a. When the camera decoration assembly 300 is in the third state, the included angle formed by the first rod 25 and the second rod 26 may be an eighth included angle β3. The eighth included angle β3 can be 180 degrees, or, in the Z-axis direction, the opening of the eighth included angle β3 can face the positive direction of the Z-axis, that is, the first direction.

[0257] It is understood that when the camera decoration assembly 300 in this embodiment is in the second state, the driving member 28 of the lifting device 310 can continue to drive the second rod 26 to rotate relative to the base 30 in the second rotation direction b until the stop protrusion 263 contacts / abuts the base 30 (i.e., the baffle 35 in this embodiment) to switch to the third state. When the camera decoration assembly 300 is in the third state, the included angle between the first rod 25 and the second rod 26 (i.e., the eighth included angle β3 in this embodiment) can be 180 degrees, or the opening of the eighth included angle β3 can face the first direction. In this way, when the camera decoration assembly 300 is in the third state and the eighth included angle β3 is 180°, even if the camera decoration 320 is subjected to external force and has a tendency to move in the second direction, since the relative position between the first rod 25 and the second rod 26 is a dead point, no relative rotation will occur between the first rod 25 and the second rod 26. Meanwhile, the connecting member 24 and the first transmission member 11 will not rotate relative to each other under the action of the torsion spring 22 (please refer to...). Figure 21a and Figure 21b (as shown), so that the mounting part 40 can remain stationary relative to the base 30, thereby allowing the camera decoration part 320 to remain stationary relative to the base 30.

[0258] When the camera decoration assembly 300 is in the third state, and the opening of the eighth included angle β3 faces the first direction, even if the camera decoration 320 is subjected to external force and has a tendency to move along the second direction, the first rod 25, under the action of the connecting member 24, has a tendency to rotate relative to the second rod 26 along the second rotation direction b. The second rod 26, under the action of the first rod 25, has a tendency to rotate relative to the base 30 along the second rotation direction b. At this time, the stop protrusion 263 of the second rod 26 can abut against the baffle 35, so that the second rod 26 can remain stationary relative to the base 30, and the first rod 25 can also remain stationary relative to the base 30. At the same time, the connecting member 24 and the first transmission member 11 will not rotate relative to each other under the action of the torsion spring 22, so that the mounting member 40 can remain stationary relative to the base 30, and thus the camera decoration 320 can remain stationary relative to the base 30.

[0259] In other words, in the second state, the camera decoration assembly 300 in this embodiment can also control the second rod 26 to continue rotating relative to the base 30 in the second rotation direction b to the third state, so that the stop protrusion 263 of the second rod 26 can contact part of the base 30, and the included angle between the first rod 25 and the second rod 26 can be equal to 180° or the opening of the included angle can face the first direction, thereby providing a buffering effect for the camera decoration assembly 300, so that the camera decoration 320 can remain stationary relative to the base 30 even if it is subjected to external force, which is beneficial to improving the user experience, and can also protect the drive member 28, which is beneficial to extending the service life of the camera decoration assembly 300. In other embodiments, the baffle 35 can also be fixedly connected to the first sidewall 31a and / or the second sidewall 31b of the base 30.
