Description
Lifting mechanism, camera module and electronic equipment
[0001] This application claims priority to Chinese patent application filed on July 17, 2024, with application number 202410964048.8 and entitled "Lifting Mechanism, Camera Module and Electronic Equipment", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of electronic product technology, and in particular to a lifting mechanism, a camera module, and an electronic device. Background Technology
[0003] With the rapid development of technology, mobile phones, tablets, and other electronic devices have become an indispensable part of people's lives. In particular, electronic devices with camera functions are widely favored by users. As people's needs continue to change, their requirements for the functions and performance of cameras are getting higher and higher. In order to improve the performance of cameras and make them more powerful, the size of the camera needs to be made larger. This results in the electronic device's appearance protruding significantly and making it prone to damage. Summary of the Invention
[0004] This application provides a lifting mechanism, a camera module, and an electronic device to improve the problem that the large size of the camera in the electronic device leads to a serious protrusion in the appearance of the electronic device, making it easy to be damaged.
[0005] To achieve the above objectives, the embodiments of this application provide the following solutions:
[0006] On one hand, a lifting mechanism is provided, including a base, a lifting member, and a first driving assembly. The base includes a first surface and a second surface facing each other, with the direction from the first surface to the second surface being the ejection direction; the lifting member and the base are arranged along the ejection direction, and the lifting member and the base are slidably connected along the ejection direction; the lifting member includes a first driving groove, the extension direction of the first driving groove intersecting the ejection direction; the first driving assembly is mounted on the base, and the first driving assembly includes a first driving member and a first swing member; a first end of the first swing member is connected to the first driving member, and a second end of the first swing member is slidably connected to the first driving groove.
[0007] When the lifting mechanism is in the retracted state, the distance between the lifting member and the first surface in the pop-out direction is a first distance. During the transition from the retracted state to the pop-out state, the first swing member moves in the pop-out direction via the first drive member. When the lifting mechanism is in the pop-out state, the distance between the lifting member and the first surface in the pop-out direction is a second distance, which is greater than the first distance.
[0008] With the above configuration, when the lifting mechanism is in the retracted state, the distance between the lifting member and the first surface is small, allowing at least a portion of the camera module to retract into the accommodating cavity, thereby preventing damage to the camera module. During the transition from the retracted state to the pop-out state, the first swing member moves in the pop-out direction via the first driving member. The movement of the second end of the first swing member can be decomposed into two parts: one part is a movement component in the extension direction of the first driving groove, which allows the second end of the first swing member to slide within the first driving groove; the other part is a movement component in the pop-out direction, which causes the first swing member to drive the lifting member to move along the pop-out direction, increasing the distance between the lifting member and the first surface. When the lifting mechanism is in the pop-out state, at least a portion of the camera module can extend from the accommodating cavity, increasing the usable optical space of the camera module and enabling high-quality shooting.
[0009] In some embodiments, when the lifting mechanism is in the pop-out state, the direction from the first end of the first swing member to the second end of the first swing member is parallel to the pop-out direction. With this configuration, when the lifting mechanism is in the pop-out state and subjected to impacts such as falling or pressing, the impact force on the lifting member can be prevented from being transmitted to the first driving member through the first swing member, thereby protecting the first driving member and improving its reliability.
[0010] In some embodiments, when the lifting mechanism is in the pop-out state, the second end of the first swing member contacts the side wall of the first driving slide in the extending direction of the first driving slide. With this arrangement, the side wall of the first driving slide can prevent the second end of the first swing member from continuing to move, which helps ensure that the direction from the first end of the first swing member to the second end of the first swing member is parallel to the pop-out direction, thus ensuring strong support of the first swing member for the lifting mechanism and further guaranteeing the reliability of the first driving mechanism.
[0011] In some embodiments, when the lifting mechanism is in the retracted state, the distance between the second end of the first swing member and the first surface in the pop-out direction is a third distance; when the lifting mechanism is in the pop-out state, the distance between the second end of the first swing member and the first surface in the pop-out direction is a fourth distance, and the fourth distance is greater than the third distance. With the above configuration, during the transition of the lifting mechanism from the retracted state to the pop-out state, the second end of the first swing member rotates relative to the first end of the first swing member in a direction away from the first surface, thereby increasing the distance between the second end of the first swing member and the first surface.
[0012] In some embodiments, the extension direction of the drive slide is parallel to the first direction, the rotation axis of the first swing member is parallel to the second direction, the second direction is perpendicular to the first direction, and the ejection direction is perpendicular to the plane containing the first and second directions. This arrangement helps to prevent the second end of the first swing member from getting stuck when sliding within the first drive slide.
[0013] In some embodiments, the distance between the first end and the second end of the first swing member is less than the dimension of the first drive groove along the first direction. With this configuration, during the transition of the lifting mechanism from the retracted state to the extended state, the rotation angle of the second end of the first swing member relative to the first end is smaller, thereby reducing the motion component of the second end of the first swing member in the extended direction, resulting in a smaller distance that the first swing member drives the lifting member to move along the extended direction.
[0014] In some embodiments, when the lifting mechanism is in the retracted state, the distance between the first end of the first swing member and the first surface in the pop-out direction is greater than the distance between the second end of the first swing member and the first surface. In the first direction, the second end of the first swing member does not contact the sidewall of the drive slide. With this configuration, during the transition from the retracted state to the pop-out state, the second end of the first swing member needs to rotate more than 90° relative to its first end. Compared to embodiments where a smaller rotation of the first swing member is sufficient to achieve the transition from the retracted state to the pop-out state (e.g., the second end of the first swing member rotates less than 90° relative to its first end), in this embodiment, the dimension from the first end of the first swing member to the second end of the second swing member can be reduced, thereby reducing the space occupied by the first drive assembly.
[0015] In some embodiments, the first driving member includes a drive motor, the output shaft of which is connected to a first end of the first swing member. With this configuration, during the transition from a retracted state to an extended state, the output shaft of the drive motor can drive the first swing member to rotate.
[0016] In some embodiments, the first driving component further includes a reducer, with the output shaft of the drive motor connected to the input shaft of the reducer, and the output shaft of the reducer connected to the first end of the first swinging component. The first swinging component and the drive motor are located on the same side of the reducer. With this arrangement, the reducer can reduce the rotational speed of the first swinging component while transmitting power, to meet the lifting rate requirements of the camera module. Since both the first swinging component and the drive motor are located on the same side of the reducer, it is beneficial to improve the compactness of the first driving component's layout and reduce the space occupied by the first driving component.
[0017] In some embodiments, the lifting component further includes a second drive slide groove, which is spaced apart from the first drive slide groove along a second direction, and the extension direction of the second drive slide groove intersects the pop-out direction. The lifting mechanism also includes a second drive assembly mounted on a base, which is arranged along the second direction with the first drive assembly. The second drive assembly includes a second drive member and a second swing member, with a first end connected to the second drive member and a second end slidably connected to the second drive slide groove. During the transition from a retracted state to a pop-out state, the second swing member rotates towards the pop-out direction via the second drive member. With this configuration, during the transition from a retracted state to a pop-out state, the movement of the second swing member towards the pop-out direction via the second drive member allows at least a portion of the camera module to extend from the receiving cavity, thereby increasing the available optical space of the camera module and achieving high-quality shooting.
[0018] In some embodiments, the first drive assembly and the second drive assembly are arranged symmetrically about the center of the lifting member. With this arrangement, during the process of the lifting mechanism switching from the retracted state to the extended state, the driving forces of the first drive assembly and the second drive assembly on the lifting member can also be arranged symmetrically, so that the lifting member is subjected to uniform force, which is beneficial to improving the smoothness of the movement of the lifting member along the extended direction.
[0019] In some embodiments, the lifting mechanism includes a first slide rail, a rolling element, and a second slide rail. The first slide rail is connected to the base, and the second slide rail is connected to the lifting component. The first slide rail has a first groove, and the second slide rail has a second groove. The extending directions of both the first and second grooves are parallel to the ejection direction. The rolling element is rotatably disposed between the first and second grooves. With this arrangement, the rolling element can roll between the first and second grooves, allowing the first slide rail to move relative to the second slide rail. The first and second slide rails act as guides, enabling the lifting component and the base to move relative to each other via the first and second slide rails, thus ensuring smooth movement between the lifting component and the base.
[0020] In some embodiments, there are multiple rolling elements spaced apart along the ejection direction. The lifting mechanism also includes a retainer located between the first and second slide rails. The retainer includes multiple mounting holes spaced apart along the ejection direction, with each rolling element mounted in one mounting hole. By using multiple rolling elements, it is beneficial to further reduce the frictional force of the second slide rail relative to the first slide rail, and to further improve the smoothness of movement between the lifting component and the base.
[0021] In some embodiments, the first slide rail includes a first stop plate and a second stop plate arranged along the pop-out direction. In the pop-out direction, the distance between the first stop plate and the first surface is greater than the distance between the second stop plate and the first surface. When the lifting mechanism is in the retracted state, the second slide rail contacts the second stop plate; when the lifting mechanism is in the pop-out state, the second slide rail contacts the first stop plate. Through the above arrangement, both the first stop plate and the second stop plate can serve a limiting function.
[0022] In some embodiments, the lifting mechanism further includes a structural component and an elastic body. The structural component is slidably connected to the lifting component along the pop-out direction, and the elastic body is disposed between the lifting component and the structural component along the pop-out direction. When the lifting mechanism is in the pop-out state and is subjected to an external impact, the structural component moves towards the lifting component under the action of the external impact force, so that the elastic body is in a compressed state. At this time, since the elastic body can absorb part of the external impact force, it helps to prevent the external impact force from being transmitted to the lifting component, and then to the first or second driving component through the first or second swing component, thereby helping to protect the first or second driving component and improving its reliability.
[0023] In some embodiments, the structural component includes a first guide post, the lifting component includes a second guide post, and the elastic body is sleeved on the first and second guide posts. Through this arrangement, the first and second guide posts can guide the elastic body.
[0024] On the other hand, embodiments of this application provide a camera module, including a lens assembly and a lifting mechanism as described in any of the above embodiments, wherein the lifting mechanism is sleeved outside the lens assembly.
[0025] The camera module provided in the embodiments of this application includes the lifting mechanism as described above, and therefore has all the above-described beneficial effects, which will not be repeated here.
[0026] On the other hand, this application provides an electronic device, including a housing and a camera module as described in the above embodiments, wherein the camera module is disposed on the housing.
[0027] In some embodiments, the housing is configured as a receiving cavity. When the lifting mechanism in the camera module is in the retracted state, the lens assembly of the camera module is located inside the receiving cavity. During the transition from the retracted state to the pop-out state, the lens assembly of the camera module moves in the pop-out direction. When the lifting mechanism in the camera module is in the pop-out state, a portion of the lens assembly of the camera module is located outside the receiving cavity.
[0028] The electronic device provided in the embodiments of this application includes the camera module as described above, and therefore has all the above-described beneficial effects, which will not be repeated here. Attached Figure Description

[0050] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0051] In the following description, the terms "first," "second," etc., are used for ease of description only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.
[0052] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0053] In the embodiments of this application, the directional indications used to explain the structure and movement of different components, such as up, down, left, right, front, and back, are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.
[0054] In the embodiments of this application, "parallel" and "perpendicular" include the described situation and situations similar to the described situation, the range of which is within an acceptable deviation range, wherein the acceptable deviation range is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°.
[0055] This application provides an electronic device, which may include mobile phones, tablets, smart bracelets, smartwatches, etc. This application does not limit the scope of the electronic device. The electronic device includes a camera module, which enables functions such as taking photos and recording videos.
[0056] The following description uses a mobile phone as an example of an electronic device. It should be understood that the electronic device in this application is not limited to a mobile phone. Figure 1a is an exploded view of the structure of an electronic device provided in this application embodiment. Referring to Figure 1a, the electronic device 1 includes a housing 12 and a display panel 11. The housing 12 may include a middle frame 13 and a back cover 14. The display panel 11 covers one side of the middle frame 13, and the back cover 14 covers the other side of the middle frame 13. The middle frame 13 and the back cover 14 can form a cavity 15. The electronic device 1 also includes a battery 16 and a motherboard 17 disposed in the cavity 15. The motherboard 17 and the battery 16 can be fixed on the middle frame 13. The motherboard 17 is electrically connected to the battery 16 and the display panel 11.
[0057] In some embodiments, the camera module 2 can be a rear camera. Accordingly, the camera module 2 can be mounted on the rear cover 14 of the housing 12. The camera module 2 can be electrically connected to the motherboard 17 so that the camera module 2 can take pictures or record videos under the control of the motherboard 17.
[0058] In this embodiment, the camera module 2 includes a lens assembly. The lens assembly includes a light-transmitting cover plate, an optical lens, and an optical sensor. The light-transmitting cover plate, optical lens, and optical sensor can be arranged along the optical axis. The optical sensor is located on the image side of the optical lens, and the light-transmitting cover plate is located on the object side of the optical lens. External light passes through the light-transmitting cover plate and the optical lens and is received by the optical sensor to form an image. The optical sensor is electrically connected to the motherboard 17 shown in Figure 1a to convert the received image into an electrical signal and send it to the motherboard 17, thereby enabling photography or video recording.
[0059] Figure 1b is a structural diagram of a camera module provided in an embodiment of this application. Referring to Figure 1b, in this embodiment, the camera module 2 further includes a lifting mechanism 200, which is sleeved on the lens assembly 21. When the lens assembly 21 moves up and down, the lifting mechanism 200 also moves up and down, providing lifting space for the lens assembly 21.
[0060] Referring to Figures 1a and 1b, when the lifting mechanism 200 in the camera module 2 is in the retracted state, at least a portion of the lens assembly 21 of the camera module 2 is located inside the receiving cavity 15, wherein the portion of the lens assembly 21 located inside the receiving cavity 15 is the first portion; during the process of the lifting mechanism 200 switching from the retracted state to the pop-out state, the lens assembly 21 of the camera module 2 moves along the pop-out direction; when the lifting mechanism 200 in the camera module 2 is in the pop-out state, a portion of the lens assembly 21 of the camera module 2 is located outside the receiving cavity 15, wherein the portion of the lens assembly 21 located inside the receiving cavity 15 is the second portion, and in the pop-out direction, the size of the second portion is smaller than the size of the first portion. The pop-out direction can be perpendicular to the rear cover.
[0061] Referring to Figures 1a and 1b, the rear cover 14 has an opening 18, which communicates with the receiving cavity 15. The pop-out direction can be the thickness direction of the rear cover 14. When the lifting mechanism 200 is in the retracted state, at least a portion of the lens assembly 21 can be positioned directly opposite the opening 18, and at least a portion of the lens assembly 21 is located inside the receiving cavity 15. During the transition from the retracted state to the pop-out state, the lifting mechanism 200 can cause a portion of the lens assembly 21 to extend out of the receiving cavity 15 through the opening 18. When the lifting mechanism 200 is in the pop-out state, at least a portion of the lens assembly 21 can be positioned directly opposite the opening 18, and at least a portion of the lens assembly 21 is located outside the receiving cavity 15.
[0062] With the above settings, when taking pictures using the electronic device 1, at least a portion of the camera module 2 extends out of the housing cavity 15 to increase the available optical space of the camera module 2 and achieve high-quality shooting; when shooting is not required, at least a portion of the camera module 2 retracts into the housing cavity 15 to avoid the camera module 2 protruding too much from the housing and affecting the appearance of the electronic device 1.
[0063] Figure 2 is a structural diagram of a lifting mechanism 200 in a retracted state according to an embodiment of this application; Figure 3 is a structural diagram of a lifting mechanism 200 in a pop-up state according to an embodiment of this application; Figure 4 is an exploded view of a lifting mechanism 200 according to an embodiment of this application. The structure of the lifting mechanism 200 will be described below with reference to Figures 2, 3 and 4.
[0064] In this embodiment, the lifting mechanism 200 includes a base 210. The base 210 can be mounted on the rear cover 14, and the base 210 can be located on the side of the rear cover 14 closer to the display panel 11. For example, the lifting mechanism 200 may include a cover 220, and the cover 220 and the base 210 can be detachably connected so that the cover 220 and the base 210 together enclose an accommodating space N, at least a portion of which is located within the aforementioned accommodating cavity 15.
[0065] Figure 5 is an exploded view of a base 210, a first driving component 250, and a lifting component 240 provided in an embodiment of this application; Figure 6 is a structural diagram of a base 210 provided in an embodiment of this application. Referring to Figures 5 and 6, the base 210 may include opposing first surfaces 2101 and second surfaces 2102. For example, the base 210 may include a base plate 211 and a boss 212, wherein the lower surface of the base plate 211 can be the first surface 2101 of the base 210, the upper surface of the base plate 211 can be the second surface 2102 of the base 210, the boss 212 can be located on the upper surface of the base plate 211, and the boss 212 and the base plate 211 can be an integral structure. The base 210 may also have a first through hole 219 penetrating the boss 212 and the base plate 211, and the lens assembly 21 can be located within the first through hole 219 so that the base 210 is fitted onto the lens assembly 21. Of course, the structure of the base 210 is only exemplary, and the specific structure of the base 210 is not limited in this application embodiment.
[0066] For example, in an embodiment where the base plate 211 is generally a rectangular flat plate, the direction from the first surface 2101 to the second surface 2102 can be the thickness direction of the base plate 211. For ease of explanation, the direction from the first surface 2101 to the second surface 2102 is defined as the ejection direction Z, the width direction of the base plate 211 is referred to as the first direction X, and the length direction of the base plate 211 is referred to as the second direction Y. The ejection direction Z is perpendicular to the plane containing the first direction X and the second direction Y.
[0067] As shown in Figure 4, the cover 220 can be threadedly connected to the base plate 211 of the base 210, and the cover 220 can also be bonded to the inner wall of the rear cover 14 so that the lifting mechanism 200 can be mounted on the rear cover 14. For example, the surface of the cover 220 facing away from the base 210 (e.g., the upper surface of the cover 220 in Figure 4) can be bonded to the inner wall of the rear cover 14. The cover 220 can be provided with a second through hole 229 corresponding to the first through hole 219, and the second through hole 229 also corresponds to the opening of the rear cover 14. During the process of the lifting mechanism 200 switching from a retracted state to an extended state, a portion of the lens assembly 21 extends from the accommodating space N through the second through hole 229, so that a portion of the lens assembly 21 can extend from the accommodating cavity 15 through the opening of the rear cover 14.
[0068] As shown in Figure 5, in this embodiment of the application, the lifting mechanism 200 further includes a lifting component 240 and a first drive assembly 250. Both the lifting component 240 and the first drive assembly 250 are mounted on the base 210. Figure 7 is an exploded view of a lifting component and structural component provided in this embodiment of the application. The structure of the lifting component 240 will be described in conjunction with Figures 5 and 7.
[0069] In this embodiment, at least a portion of the lifting member 240 and the base 210 are arranged along the pop-out direction Z, and the lifting member 240 and the base 210 are slidably connected along the pop-out direction Z. The orthographic projection of the lifting member 240 on a plane perpendicular to the pop-out direction Z can overlap at least a portion of the orthographic projection of the base 210 on the same plane. For example, the lifting member 240 can be generally cylindrical, and can be fitted over the boss 212 of the base 210, and can be slidably connected to the boss 212 along the pop-out direction Z. For instance, the lifting member 240 and the boss 212 of the base 210 can be slidably connected via a groove and a slider. This embodiment does not specifically limit the slidable connection method between the lifting member 240 and the base 210. Through the above arrangement, the lifting member 240 can be slidably connected to the boss 212 of the base 210 along the pop-out direction Z, and the lifting member 240 can be arranged with the base plate 211 of the base 210 along the pop-out direction Z.
[0070] The lifting member 240 includes a first driving groove 249, the extension direction of which intersects the pop-out direction Z. For example, the first driving groove 249 may be located on the side surface of the lifting member 240 opposite to the boss 212. This application embodiment does not limit the specific shape of the first driving groove 249, as long as its extension direction intersects the pop-out direction Z.
[0071] Referring again to Figure 5, the first drive assembly 250 is mounted on the base 210. The first drive assembly 250 includes a first drive member 251 and a first swing member 252. The first end 2521 of the first swing member is connected to the first drive member 251, and the second end 2522 of the first swing member is slidably connected to the first drive groove 249. Exemplarily, the first swing member 252 can be generally rod-shaped. The first end 2521 of the first swing member can have a first protrusion 252a, which is connected to the first drive member 251. The second end 2522 of the first swing member can have a second protrusion 252b, which is slidably connected to the first drive groove 249. The first swing member 252 can be generally straight, or, in some other examples, it can be generally curved. This application does not limit the specific shape of the first swing member 252.
[0072] The first drive groove 249 extends in a direction parallel to the first direction X. For example, the first drive groove 249 can be approximately oval-shaped, and its extension direction can be parallel to the first direction X. This configuration helps prevent the second end 2522 of the first swing member from getting stuck when sliding within the first drive groove 249.
[0073] In some embodiments, the first end 2521 of the first swing member can also be mounted on the base 210. Exemplarily, as shown in FIG6, the base 210 can also include a mounting boss 213. The mounting boss 213 can have a through mounting hole 2131, and the first protrusion 252a can pass through the mounting hole 2131 and be connected to the first drive member 251. The first protrusion 252a can also be connected to the mounting hole 2131 via a snap ring. Furthermore, there can be a clearance fit between the first protrusion 252a and the mounting hole 2131 so that the first protrusion 252a can rotate within the mounting hole 2131.
[0074] Figure 8 is a structural diagram of a base 210, a first drive assembly 250, and a second drive assembly 260 provided in an embodiment of this application. In some embodiments, referring to Figure 8, the first drive member 251 may include a drive motor 2511, and the output shaft of the drive motor 2511 is connected to the first end 2521 of the first swing member. The output shaft of the drive motor 2511 and the first end 2521 of the first swing member can be directly connected, or they can be connected via a transmission component; this embodiment does not specifically limit this connection. With the above configuration, during the transition from a retracted state to an extended state, the output shaft of the drive motor 2511 can drive the first swing member 252 to rotate. Similarly, during the transition from an extended state to a retracted state, the output shaft of the drive motor 2511 can drive the first swing member 252 to rotate.
[0075] Furthermore, the rotation axis L1 of the first swing member 252 relative to the first drive member 251 can be parallel to the second direction Y. For example, the centerline of the output shaft of the drive motor 2511 can coincide with the rotation axis of the first swing member 252 relative to the first drive member 251, and the output shaft of the drive motor 2511 can be parallel to the second direction Y, so that the rotation axis of the first swing member 252 relative to the first drive member 251 can also be parallel to the second direction Y.
[0076] Referring again to Figure 8, the first driving member 251 may further include a reducer 2512. The output shaft of the drive motor 2511 is connected to the input shaft of the reducer 2512, and the output shaft of the reducer 2512 is connected to the first end 2521 of the first swing member. The first swing member 252 and the drive motor 2511 are located on the same side of the reducer 2512. For example, the output shaft of the drive motor 2511, the output shaft of the reducer 2512, and the input shaft of the reducer 2512 are all parallel to the second direction Y. With the above arrangement, the reducer 2512 can reduce the rotational speed of the first swing member 252 while transmitting power, to meet the requirements of the lifting rate of the camera module 2. The fact that the first swing member 252 and the drive motor 2511 can both be located on the same side of the reducer 2512 is beneficial for improving the compactness of the first driving member 251's layout and reducing the space occupied by the first driving member 251.
[0077] Referring to Figure 9, when the lifting mechanism 200 is in the retracted state, the distance between the lifting member 240 and the first surface 2101 in the pop-out direction Z is a first distance D1. By setting the distance between the lifting member 240 and the first surface 2101 to be small, at least a portion of the camera module 2 can be retracted into the receiving cavity 15, thus preventing the camera module 2 from protruding excessively from the housing and thereby preventing damage to the camera module 2.
[0078] Referring to Figures 9 and 10, during the transition from the retracted state to the extended state, the first swing member 252 moves in the extended direction Z via the first drive member 251. With this configuration, during the transition from the retracted state to the extended state, the first swing member 252 moves in the extended direction Z via the first drive member 251. The movement of the second end 2522 of the first swing member can be decomposed into two parts: one part is the movement component in the extension direction of the first drive groove 249, which allows the second end 2522 of the first swing member to slide within the first drive groove 249; the other part is the movement component in the extended direction Z, which allows the first swing member 252 to drive the lifting member 240 to move along the extended direction Z, increasing the distance between the lifting member 240 and the first surface 2101.
[0079] Referring to Figure 10, when the lifting mechanism 200 is in the pop-out state, the distance between the lifting member 240 and the first surface 2101 in the pop-out direction Z is a second distance D2, which is greater than the first distance D1. With the above configuration, at least a portion of the camera module 2 can extend from the accommodating cavity 15, thereby increasing the available optical space of the camera module 2 and achieving high-quality shooting.
[0080] Further referring to Figures 5 and 7, the boss 212 of the base 210 may also include a first latch 215. Correspondingly, the lifting member 240 may include a first latch 241 that cooperates with the first latch 215. When the lifting member 240 is assembled with the base 210, the lifting member 240 can be sleeved on the boss 212 of the base 210. When the lifting member 240 is in the retracted state, the first latch 241 and the first latch 215 are spaced apart. During the process of the lifting mechanism 200 switching from the retracted state to the pop-out state, the first latch 215 moves towards the first latch 241. When the lifting mechanism 200 is in the pop-out state, the first latch 215 and the first latch 241 are in contact with each other. The first latch 215 can play a limiting role to prevent the lifting member 240 from detaching from the base 210.
[0081] In some embodiments, as shown in Figures 2, 3, and 4, the lifting mechanism 200 may further include a structural member 230, which is slidably connected to the lifting member 240 along the pop-out direction Z. For example, at least a portion of the structural member 230 may be sleeved over the lifting member 240, and the inner wall of the structural member 230 may have guide ribs 237. Correspondingly, the outer wall of the lifting member 240 may have guide grooves 246, and the structural member 230 and the lifting member 240 may be slidably connected via the guide ribs 237 and the guide grooves 246.
[0082] Furthermore, a portion of the structural component 230 can also be arranged with the lens assembly 21 along the pop-out direction Z. The orthographic projection of the structural component 230 onto a plane perpendicular to the pop-out direction Z can at least partially overlap with the orthographic projection of the lens assembly 21 onto the same plane, so that the structural component 230 can shield the lens assembly 21 in the pop-out direction Z. The structural component 230 can be used to display a portion of the appearance of the camera module 2 and protect the lens assembly 21. The structural component 230 can also have a third through-hole 239, and at least a portion of the lens assembly 21 can correspond to the third through-hole 239. When the lifting mechanism 200 is in the retracted state, the distance between the structural component 230 and the rear cover 14 in the pop-out direction Z can be a first gap, where the first gap can be 0, meaning that the structural component 230 can be coplanar with at least a portion of the surface of the rear cover 14. During the transition from the retracted state to the pop-out state, the lens assembly 21 can drive the structural component 230 to move along the pop-out direction Z. When the lifting mechanism 200 is in the pop-out state, the distance between the structural component 230 and the rear cover 14 in the pop-out direction Z can be a second gap, which can be greater than the first gap.
[0083] Furthermore, referring to Figure 7, the lifting member 240 may also include a second latch 242, and correspondingly, the structural member 230 may include a second locking block 236 that cooperates with the second latch 242. The cooperation of the second latch 242 and the second locking block 236 prevents the structural member 230 from disengaging from the lifting member 240.
[0084] Figure 11 is a cross-sectional view of the structure in Figure 9 along section line AA; Figure 12 is a cross-sectional view of the structure in Figure 10 along section line BB; Figure 13 is a schematic diagram of the motion principle of a first swing member 252 provided in an embodiment of this application. In Figure 13, the dashed lines represent the positions of the first swing member and the first driving slide in the retracted state of the lifting mechanism, and the solid lines represent the positions of the first swing member and the first driving slide in the extended state of the lifting mechanism. The positions of the first swing member 252 in different states will be described below with reference to Figures 11 to 13.
[0085] In some embodiments, referring to FIG12, when the lifting mechanism 200 is in the pop-out state, the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member can be parallel to the pop-out direction Z. For example, when the first swing member 252 is generally a straight rod structure, the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member is also the extension direction of the straight rod structure of the first swing member 252.
[0086] With the above configuration, in the pop-out direction Z, the lifting member 240 can be strongly supported by the first swing member 252, so that a dead point can be formed between the lifting member 240 and the first swing member 252 in the pop-out direction Z. Here, the "dead point" refers to the angle between the normal direction of the contact point between the first drive slide 249 and the first swing member 252 and the direction pointing from the first end 2521 of the first swing member to the second end 2522 of the first swing member, which is 0 degrees. The lifting of the lifting member 240 cannot drive the rotation of the first swing member 252. When the lifting mechanism 200 is in the pop-out state and is subjected to impacts such as falling or pressing, the impact force on the lifting member 240 can be prevented from being transmitted to the first drive member 251 through the first swing member 252, thereby protecting the first drive member 251 and improving its reliability.
[0087] In some other embodiments, when there is friction between the first drive slide 249 and the first swing member 252, the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member can also intersect the ejection direction Z. In this case, a dead point can also be formed between the lifting member 240 and the first swing member 252 in the ejection direction Z. Here, "dead point" refers to the angle between the normal direction of the contact point between the first drive slide 249 and the first swing member 252 and the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member, which is greater than 0 and less than or equal to arctan(u), where u is the coefficient of friction between the first drive slide 249 and the first swing member 252.
[0088] Furthermore, referring to Figure 13, when the lifting mechanism 200 is in the pop-out state, the second end 2522 of the first swing member can contact the side wall of the first driving slide 249 in the extending direction of the first driving slide 249. When the extending direction of the first driving slide 249 is parallel to the first direction X, the first driving slide 249 includes two opposing side walls in the first direction X, one of which contacts the second end 2522 of the first swing member.
[0089] With the above configuration, the sidewall of the first drive slide 249 can be used to block the second end 2522 of the first swing member from continuing to move, which helps to ensure that the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member is parallel to the ejection direction Z, which helps to ensure the strong support of the first swing member 252 for the lifting member 240, thereby further ensuring the reliability of the first drive member 251.
[0090] In some embodiments, as shown in Figures 11 and 12, when the lifting mechanism 200 is in the retracted state, the distance between the second end 2521 of the first swing member and the first surface 2101 in the pop-out direction Z is a third distance H2. When the lifting mechanism 200 is in the pop-out state, the distance between the second end 2521 of the first swing member and the first surface 2101 in the pop-out direction Z is a fourth distance D3, which is greater than the third distance H2.
[0091] With the above settings, during the transition of the lifting mechanism 200 from the retracted state to the pop-out state, the second end 2522 of the first swing member rotates relative to the first end 2521 of the first swing member in a direction away from the first surface 2101, so that the distance between the second end 2521 of the first swing member and the first surface 2101 increases.
[0092] In some embodiments, when the lifting mechanism 200 is in the retracted state, the distance H1 between the first end 2521 of the first swing member and the first surface 2101 in the pop-out direction Z can be equal to a third distance H2 between the second end 2521 of the first swing member and the first surface 2101. That is, the direction from the first end 2521 of the first swing member to the second end 2521 of the first swing member can be parallel to the first direction X. Since when the lifting mechanism 200 is in the pop-out state, the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member is parallel to the pop-out direction Z. During the transition of the lifting mechanism 200 from the retracted state to the pop-out state, the second end 2522 of the first swing member rotates 90° relative to the first end 2521 of the first swing member.
[0093] Alternatively, in some embodiments, when the lifting mechanism 200 is in the retracted state, in the pop-out direction Z, the distance H1 between the first end 2521 of the first swing member and the first surface 2101 can be a third distance H2, which is less than the distance H2 between the second end 2521 of the first swing member and the first surface 2101. During the transition of the lifting mechanism 200 from the retracted state to the pop-out state, the angle of rotation of the second end 2522 of the first swing member relative to the first end 2521 of the first swing member is less than 90°.
[0094] Alternatively, in some embodiments, referring to FIG11, when the lifting mechanism 200 is in the retracted state, in the pop-out direction Z, the distance H1 between the first end 2521 of the first swing member and the first surface 2101 can be greater than the distance H2 between the second end 2522 of the first swing member and the first surface 2101. Referring to FIG13, when the lifting mechanism 200 is in the retracted state, the second end 2522 of the first swing member is closer to the base 210 than the first end 2521 of the first swing member, and the first drive slide 249 can have two opposing sidewalls along the first direction X. The second end 2522 of the first swing member is located between the two opposing sidewalls of the first drive slide 249 along the first direction X, and the second end 2522 of the first swing member may not contact either sidewall.
[0095] With the above settings, referring to Figure 13, during the process of the lifting mechanism 200 transitioning from the retracted state to the pop-out state, the second end 2522 of the first swing member needs to rotate relative to the first end 2521 of the first swing member by an angle greater than 90°.
[0096] When the lifting distance of the lifting member 240 is the same, compared with the above two, the embodiment that can realize the transition from the retracted state to the pop-up state by rotating the first swing member 252 by a smaller angle (for example, the second end 2522 of the first swing member rotates less than 90° relative to the first end 2521 of the first swing member). In this embodiment, since H1 is greater than H2, the dimension from the first end 2521 of the first swing member to the second end 2622 of the second swing member can be reduced, which is beneficial to reducing the space occupied by the first drive assembly 250.
[0097] When the first end 2521 of the first swing member points to the second end 2622 of the second swing member at the same size, compared with the above two, the embodiment in which the transition from the retracted state to the pop-up state can be achieved by rotating the first swing member 252 by a smaller angle is used. In this embodiment, since H1 is greater than H2, the lifting distance of the lifting member 240 is increased.
[0098] In this embodiment, the distance H3 between the first end 2521 and the second end 2522 of the first swing member can be less than or equal to the dimension H4 of the first drive groove 249 along the first direction X. Referring to Figures 11, 12, and 13, by increasing the dimension H4 of the first drive groove 249 along the first direction X, the movement distance of the second end 2522 of the first swing member within the first drive groove 249 increases, thereby increasing the motion component of the second end 2522 of the first swing member along the first direction X. Correspondingly, in order for the first end 2521 of the first swing member to rotate from the position in Figure 11 to the position in Figure 12, during the transition of the lifting mechanism 200 from the retracted state to the pop-out state, the second end 2522 of the first swing member needs to rotate at a large angle relative to the first end 2521 of the first swing member. This is beneficial to increase the motion component of the second end 2522 of the first swing member in the pop-out direction Z, and to increase the distance that the first swing member 252 drives the lifting member 240 to move along the pop-out direction Z. This is beneficial to ensure that when the lifting mechanism 200 is in the pop-out state, at least a part of the camera module 2 extends out of the accommodating cavity 15 to achieve high-quality shooting.
[0099] In some embodiments, referring to Figures 5, 7, and 8, the lifting member 240 may further include a second driving slide groove 248. The second driving slide groove 248 and the first driving slide groove 249 are spaced apart along the second direction Y, and the extending direction of the second driving slide groove 248 intersects the pop-out direction Z. Exemplarily, the structures of the second driving slide groove 248 and the first driving slide groove 249 may be identical. For example, the extending direction of the second driving slide groove 248 may also be parallel to the first direction X. Alternatively, the second driving slide groove 248 may also have other shapes; for example, the second driving slide groove 248 may also be an arc-shaped slide groove. This application embodiment does not limit the specific shape of the second driving slide groove 248.
[0100] Based on the above structure, the lifting mechanism 200 may further include a second drive assembly 260, which can be mounted on the base 210. The second drive assembly 260 and the first drive assembly 250 are arranged along the second direction Y. The second drive assembly 260 includes a second drive member 261 and a second swing member 262. The first end 2621 of the second swing member is connected to the second drive member 261, and the second end 2622 of the second swing member is slidably connected to the second drive groove 248. For example, the second swing member 262 may be generally rod-shaped. The first end 2621 of the second swing member may have a third protrusion 262a, which is connected to the second drive member 261. The second end 2622 of the second swing member may have a fourth protrusion 262b, which is slidably connected to the second drive groove 248. The second swing member 262 may be generally straight, or, in some other examples, the second swing member 262 may be generally curved. The specific shape of the second swing member 262 is not limited in the embodiments of this application.
[0101] As described in the above embodiments, during the transition from a retracted state to a pop-up state, the second swing member 262 rotates in the pop-up direction Z via the second drive member 261. With this configuration, during the transition from a retracted state to a pop-up state, the second swing member 262 moves in the pop-up direction Z via the second drive member 261. The movement of the second end 2622 of the second swing member can be decomposed into two parts: one part is a movement component in the extension direction of the second drive groove 248, which allows the second end 2622 of the second swing member to slide within the second drive groove 248; the other part is a movement component in the pop-up direction Z, which allows the second swing member 262 to drive the lifting member 240 to move along the pop-up direction Z, increasing the distance between the lifting member 240 and the first surface 2101. With this configuration, at least a portion of the camera module 2 can extend from the accommodating cavity 15, thereby increasing the available optical space of the camera module 2 and achieving high-quality shooting.
[0102] In some embodiments, continuing to refer to FIG8, the first drive assembly 250 and the second drive assembly 260 are centrally symmetrical about the lifting member 240. Here, "centrally symmetrical" can be understood as the first drive assembly 250 and the second drive assembly 260 being either absolutely centrally symmetrical or approximately centrally symmetrical. Approximate central symmetry can be understood as the overall structure of the first drive assembly 250 and the second drive assembly 260 exhibiting a symmetrical trend, with local variations within the first drive assembly 250 and the second drive assembly 260. A difference may exist between the dimensions of the symmetrical first drive assembly 250 and the second drive assembly 260, provided that the fluctuation range of the difference does not exceed an error threshold. This disclosure does not limit the specific value of the error threshold, ensuring that the gap is within the error threshold range.
[0103] For example, the second drive member 261 and the first drive member 251 may have the same structure. For instance, the second drive member 261 may also include a drive motor 2611 and a reducer 2612, wherein the drive motor 2611 of the second drive member 261 and the drive motor 2511 of the first drive member 251, and the reducer 2612 of the second drive member 261 and the reducer 2512 of the first drive member 251 are symmetrically arranged about the center of the lifting member 240.
[0104] For example, the first swing member 252 and the second swing member 262 are arranged symmetrically about the center of the lifting member 240. For example, the structures of the first swing member 252 and the second swing member 262 can be the same. When the second end 2522 of the first swing member slides in the first drive slide groove 249 and the second end 2622 of the second swing member slides in the second drive slide groove 248, the motion component of the second end 2522 of the first swing member in the extending direction of the first drive slide groove 249 is parallel to and opposite to the motion component of the second end 2622 of the second swing member in the extending direction of the second drive slide groove 248, so that the sliding direction of the second end 2522 of the first swing member when sliding in the first drive slide groove 249 and the sliding direction of the second end 2622 of the second swing member when sliding in the second drive slide groove 248 can be parallel to and opposite to each other.
[0105] Similarly, when the lifting mechanism 200 is in the pop-out state, the direction from the first end 2621 of the second swing member to the second end 2622 of the second swing member can be parallel to the pop-out direction Z. In the extension direction of the second drive slide 248, the second end 2622 of the second swing member can contact the side wall of the second drive slide 248. With the above arrangement, in the pop-out direction Z, the lifting member 240 can be strongly supported by the second swing member 262, so that a dead point can be formed between the lifting member 240 and the second swing member 262 in the pop-out direction Z. When the lifting mechanism 200 is in the pop-out state and is subjected to impacts such as falling or pressing, the impact force on the lifting member 240 can be prevented from being transmitted to the second drive member 261 through the second swing member 262, thereby helping to protect the second drive member 261 and improving the reliability of the second drive member 261.
[0106] Similarly, when the lifting mechanism 200 is in the retracted state, in the pop-out direction Z, the distance between the first end 2521 of the first swing member and the first surface 2101 can be greater than the distance between the second end 2522 of the first swing member and the first surface 2101. The second end 2522 of the first swing member does not contact the sidewall of the second drive slide 248 in the first direction X. With this configuration, during the transition of the lifting mechanism 200 from the retracted state to the pop-out state, the second end 2522 of the first swing member needs to rotate more than 90° relative to the first end 2521 of the first swing member. The dimension from the first end 2521 of the first swing member to the second end 2622 of the second swing member can be reduced, thereby helping to reduce the space occupied by the first drive assembly 250.
[0107] With the above settings, during the process of switching from the retracted state to the pop-out state, the driving force of the first driving component 250 and the driving force of the second driving component 260 on the lifting component 240 can also be centrally symmetrically arranged, so that the lifting component 240 is subjected to uniform force, which is beneficial to improving the smoothness of the movement of the lifting component 240 along the pop-out direction Z.
[0108] In some embodiments, referring to FIG14a, the lifting mechanism 200 may further include a first sensor 293, a second sensor 294, a first circuit board 291, and a second circuit board 292. The first sensor 293 may be mounted on the first circuit board 291, and the second sensor 294 may be mounted on the second circuit board 292. The first circuit board 291 and the second circuit board 292 may also be connected to the motherboard of the electronic device 1. The first sensor 293 and the second sensor 294 may be magnetic sensors, such as Hall effect sensors, TMR (Tunnel Magneto Resistance) sensors, etc.
[0109] Taking the first circuit board 291 in Figure 14b as an example, the mounting method of the first circuit board 291 and the second circuit board 292 will be described. For example, the mounting boss 213 parallel to the base 210 can be spaced apart from the boss 212 of the base 210. The first circuit board 291 can be a flexible circuit board, and it can be bonded to a sheet metal part 299. The sheet metal part 299 is also bonded to the surface of the mounting boss 213 facing the boss 212. Similarly, the second circuit board 292 can also be bonded to a sheet metal part and mounted on the surface of the mounting boss 213 facing the boss 212 via the sheet metal part.
[0110] Accordingly, the lifting mechanism 200 may also include a first magnetic element 2471 and a second magnetic element 2472. The first magnetic element 2471 and the second magnetic element 2472 may be disposed on the lifting member 240 so that the first magnetic element 2471 and the second magnetic element 2472 can move together with the lifting member 240.
[0111] Taking the first magnetic element 2471 in Figure 14b as an example, the mounting method of the first magnetic element 2471 and the second magnetic element 2472 will be described. For example, the surface of the lifting member 240 facing the mounting boss 213 may have a mating groove 245, and the first magnetic element 2471 can be mounted in the mating groove 245. Similarly, the second magnetic element 2472 can also be mounted in the groove provided on the lifting member 240 facing the mounting boss 213.
[0112] With the above settings, when the first magnetic component 2471 and the second magnetic component 2472 move with the lifting component 240, the magnetic fields of the first magnetic component 2471 and the second magnetic component 2472 collected by the first sensor 293 and the second sensor 294 change, so that the data transmitted from the first sensor 293 to the first circuit board 291 changes, and the data transmitted from the second sensor 294 to the second circuit board 292 changes. The main board of the electronic device 1 can obtain the position information of the lifting mechanism 200 through the magnetic field information collected by the first sensor 293 and the second sensor 294.
[0113] In some embodiments, referring to Figures 9, 10, 15, 16, and 17, the lifting mechanism 200 may further include a first slide rail 271, a rolling element 274, and a second slide rail 272. The first slide rail 271 may be connected to the base 210, the second slide rail 272 may be connected to the lifting member 240, and the rolling element 274 may be rotatably disposed between the first slide rail 271 and the second slide rail 272.
[0114] For example, referring to Figure 6, the outer side of the boss 212 may have a first engaging groove 218, the first engaging groove 218 having an engaging hole 2181 penetrating the bottom of the groove, the first slide rail 271 may be disposed in the first engaging groove 218, and the first slide rail 271 may engage with the engaging hole 2181, so that the first slide rail 271 can be detachably connected to the base 210. For example, referring to Figure 7, the inner side of the lifting member 240 may have a second engaging groove 243, the second slide rail 272 may engage with the second engaging groove 243, so that the second slide rail 272 can be detachably connected to the lifting member 240.
[0115] Referring to Figure 17, the first slide rail 271 may have a first groove 2713, the extension direction of which may be parallel to the pop-out direction Z. For example, the first slide rail 271 may be generally plate-shaped, the extension direction of which may be the length direction of the plate-shaped structure. Along the width direction of the plate-shaped structure, the first slide rail 271 may have two opposing first folded edges 2714. One first folded edge 2714 may be recessed away from the other first folded edge 2714 to form the first groove 2713. The bottom of the first groove 2713 may include an arc surface.
[0116] Furthermore, the first slide rail 271 may also include a first stop plate 2711 and a second stop plate 2712 arranged along the ejection direction Z. In the ejection direction Z, the distance between the first stop plate 2711 and the first surface 2101 is greater than the distance between the second stop plate 2712 and the first surface 2101. For example, the first stop plate 2711 may be located at the upper end of the first slide rail 271, and the second stop plate 2712 may be located at the lower end of the second slide rail 272.
[0117] The second slide rail 272 may have a second groove 2723, the extension direction of which may be parallel to the ejection direction Z. The second slide rail 272 may be generally plate-shaped, the extension direction of which may be the length direction of the plate-shaped structure. Along the width direction of the plate-shaped structure, the second slide rail 272 may have two opposing second folded edges 2724. One second folded edge 2724 may be recessed toward the other second folded edge 2724 to form a second groove 2723. The bottom of the second groove 2723 may include an arc surface.
[0118] The rolling element 274 is rotatably disposed between the first slide groove 2713 and the second slide groove 2723. For example, the shape of the rolling element 274 may include a sphere, and it can be rotatably disposed between the bottom of the first slide groove 2713 and the bottom of the second slide groove 2723. With this arrangement, the rolling element 274 can roll between the first slide groove 2713 and the second slide groove 2723, allowing the first slide rail 271 to move relative to the second slide rail 272. The first and second slide rails 271 and 272 act as guides, enabling the lifting member 240 and the base 210 to move relative to each other via the first and second slide rails 271 and 272, thus ensuring smooth movement between the lifting member 240 and the base 210.
[0119] In some embodiments, referring to Figures 15 and 16, when the lifting mechanism 200 is in the retracted state, the second slide rail 272 can contact the second stop plate 2712. When the lifting mechanism 200 is in the extended state, the second slide rail 272 can contact the first stop plate 2711. For example, at least a portion of the second slide rail 272 can be located between the first stop plate 2711 and the second stop plate 2712. With the above configuration, both the first stop plate 2711 and the second stop plate 2712 can serve a limiting function. Specifically, the first stop plate 2711 can prevent the second slide rail 272 from continuing to move away from the first surface 2101, and the second stop plate 2712 can prevent the second slide rail 272 from continuing to move towards the first surface 2101, thereby preventing the second slide rail 272 from disengaging from the first slide rail 271 during sliding.
[0120] In some embodiments, the number of rolling elements 274 can be multiple, and the multiple rolling elements 274 can be spaced apart along the pop-out direction Z. The lifting mechanism 200 also includes a retainer 273, which is located between the first slide groove 2713 and the second slide groove 2723. The retainer 273 includes multiple mounting holes 2742 spaced apart along the pop-out direction Z, and a rolling element 274 is mounted in one mounting hole 2742.
[0121] For example, as shown in Figure 17, the retainer 273 can be generally plate-shaped. Along the width of this plate-shaped structure, the retainer 273 can have two opposing third folded edges 2741. Along the pop-out direction Z, the third folded edges 2741 can have multiple equally spaced mounting holes 2742, which penetrate through the third folded edges 2741. The number of rolling elements 274 and the number of mounting holes 2742 can be the same, so that the rolling elements 274 and mounting holes 2742 can be arranged in a one-to-one correspondence. Furthermore, along the pop-out direction Z, the distance between the retainer 273 and the first stop plate 2711 is twice the distance between the second slide rail 272 and the first stop plate 2711. During the transition from the retracted state to the pop-out state, the length of the travel of the second slide rail 272 along the pop-out direction Z is twice the length of the travel of the retainer 273.
[0122] By providing a retainer 273, it is beneficial to guide and hold the multiple rolling elements 274 between the first slide rail 271 and the second slide rail 272. By providing multiple rolling elements 274, it is beneficial to further reduce the sliding friction of the second slide rail 272 relative to the first slide rail 271, and to further improve the smoothness of movement between the lifting member 240 and the base 210.
[0123] Furthermore, at least a portion of the second slide rail 272 and at least a portion of the rolling element 274 can be located within the groove enclosed by the first slide rail 271, which helps to reduce the space occupied by the second slide rail 272 and the rolling element 274 and improve the compactness of the structural layout of the lifting mechanism 200.
[0124] Referring again to Figures 9 and 10, the first slide rail 271, the retainer 273, the second slide rail 272, and the multiple rolling elements 274 can together constitute a guide assembly. The lifting mechanism 200 can include multiple guide assemblies, and the guide assemblies can be equally spaced along the circumferential direction of the boss 212.
[0125] In some embodiments, referring to Figures 4, 18, and 19, the lifting mechanism 200 may further include an elastic body 280, which is disposed between the lifting member 240 and the structural member 230 along the ejection direction Z. For example, the elastic body 280 may include a spring, one end of which may contact the lifting member 240, and the other end of which may contact the structural member 230.
[0126] In some embodiments, structural member 230 may include a first guide post 238, lifting member 240 may include a second guide post 247, and elastic body 280 may be sleeved on the first guide post 238 and the second guide post 247. With the above arrangement, the first guide post 238 and the second guide post can guide the elastic body 280.
[0127] Referring to Figure 18, when the lifting mechanism 200 is in the pop-out state and is not subjected to external impact, the elastic body 280 is in a normal state. Referring to Figure 19, when the lifting mechanism 200 is in the pop-out state and is subjected to external impact, the structural member 230 moves towards the lifting member 240 under the action of the external impact force, so that the elastic body 280 is in a compressed state. At this time, since the elastic body 280 can absorb part of the external impact force, it helps to prevent the external impact force from being transmitted to the lifting member 240, and then transmitted to the first driving member 251 or the second driving member 261 through the first swing member 252 or the second swing member 262, thereby helping to protect the first driving member 251 or the second driving member 261 and improving the reliability of the first driving member 251 or the second driving member 261.
[0128] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
