[0009] Optionally, the waterproof component is connected to the surface of the camera assembly and moves with the camera assembly, and the hollow channel includes a first mating area and a second mating area both located on the inner wall;

Furthermore, the waterproof component located between the hollow channel and the camera assembly can partially fill the gap existing for the smooth sliding of the camera assembly, preventing external liquids or vapors from entering and improving the waterproof level of the electronic device.

Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0046] Figure 1 This is one of the structural schematic diagrams of an electronic device 100 according to an exemplary embodiment. Figure 2 This is a second schematic diagram of the structure of an electronic device 100 according to an exemplary embodiment. Figure 3 This is a schematic diagram illustrating the structure of a camera module 2 according to an exemplary embodiment. For example... Figures 1-3 As shown, the electronic device 100 may include a housing 1 and a camera module 2 disposed inside the housing 1. The housing 1 may include a hollow channel 11 extending inward from the surface of the housing, the hollow channel 11 being able to communicate with the outside through an opening 12 on the housing 1.

[0047] The camera module 2 may include a camera assembly 21 and a driving assembly 22 that cooperates with the camera assembly 21. The camera assembly 21 may pass through a hollow channel 11 and, driven by the driving assembly 22, can reciprocate relative to the hollow channel 11. Therefore, when a user needs to take a picture using the camera module 2, they can control the camera assembly 21 to extend out of the housing 1 through the opening 12, allowing it to... Figure 1 The status shown has switched to Figure 2 As shown in the image; when there is no need to take photos, it is controlled to retract into the electronic device 100, thereby ensuring the front-facing camera function of the electronic device 100 while avoiding occupying the display area of ​​the electronic device 100 and increasing the screen ratio of the electronic device 100.

[0048] Furthermore, such as Figure 3 , Figure 4 As shown, the electronic device 100 may also include a waterproof component 3, which is located between the camera assembly 21 and the hollow channel 11 and can interfere with the camera assembly 21 or the hollow channel 2 to fill the gap between the camera assembly 21 and the hollow channel 11, preventing external liquids or vapors from entering the interior of the electronic device 100 through the opening 12.

[0049] As can be seen from the above embodiments, in this disclosure, a hollow channel 11 is formed by extending the housing 1 inward. Through the cooperation between the hollow channel 11 and the camera assembly 21, the movement direction of the camera assembly 21 can be limited. Compared with the solution of setting a separate collar in related technologies, the assembly process is simplified and the risk of losing parts is reduced. Furthermore, the waterproof component 3 located between the hollow channel 11 and the camera assembly 21 can partially fill the gap that exists for the smooth sliding of the camera assembly 21, preventing external liquids or vapors from entering and improving the waterproof level of the electronic device 100.

[0050] It should be noted that the interference between the waterproof component 3 and the hollow channel 11 and camera assembly 21 can be manifested as follows: when the waterproof component 3 is located between the camera assembly 21 and the hollow channel 11, the waterproof component 3, due to its thickness being greater than the gap between the hollow channel 11 and the camera assembly 21, deforms under the action of the camera assembly 21 or the hollow channel 11. Specifically, when the waterproof component 3 is fixedly connected to the camera assembly 21, it can interfere with the inner wall of the hollow channel 11; when the waterproof component 3 is fixedly connected to the inner wall of the hollow channel 11, it can interfere with the surface of the camera assembly 21.

[0051] In this embodiment, it is assumed that the waterproof component 3 is connected to the surface of the camera assembly 21 and moves with the camera assembly 21. The hollow channel 11 may include a first mating area 111 and a second mating area 112 located on the inner wall side. Figure 4 As shown, when the camera assembly 21 is in the first preset position, that is, when the camera assembly 21 is housed at the boundary position inside the electronic device 100, the first mating area 111 interferes with the waterproof component 3, thereby achieving the purpose of waterproofing. Figure 5 As shown, when the camera assembly 21 is in the second preset position, that is, when the camera assembly 21 extends to the outside of the electronic device 100 and is in another boundary position, the second mating area 112 interferes with the waterproof component 3 to achieve waterproofing. Based on this, whether the camera assembly 21 is inside or outside the electronic device 100, waterproofing can be achieved through the mating between the waterproof component 3 and the hollow channel 11.

[0052] Furthermore, when the waterproof component 3 is connected to the camera assembly 21, since the thickness of the waterproof component 3 is greater than the gap between the camera assembly 21 and the inner wall of the hollow channel 11, in order to avoid continuous interference between the waterproof component 3 and the inner wall of the hollow channel 11 during the movement of the camera assembly 21, it is still... Figure 4 , Figure 5 As shown, the hollow channel 3 may also include a clearance area 113 located between the first mating area 111 and the second mating area 112. The clearance area 113 is offset from the outside of the housing 1 relative to the first mating area 111 and the second mating area 112, so that when the waterproof component 3 passes through the clearance area 113, it is in contact or separated from the inner wall of the hollow channel 3, which can reduce the resistance caused by the hollow channel 11 to the movement of the camera assembly 21 and improve the smoothness of the movement of the camera assembly 21.

[0053] A small gap may exist between the first mating area 111 or the second mating area 112 and the surface of the camera assembly 21 to improve the smoothness of the sliding of the camera assembly 21. This gap can be between 0.05-0.1mm. A gap may also exist between the clearance area 113 and the surface of the camera assembly 21, and this gap is larger than the gap between the first mating area 111 or the second mating area 112 and the surface of the camera assembly 21. For example, the gap between the clearance area 113 and the surface of the camera assembly 21 can be between 0.12mm-0.25mm. The length of the clearance area 113 is related to the length of the hollow channel 11 and the distance between the first mating area 111 and the second mating area 112, and can be designed as needed.

[0054] In the above embodiments, the waterproof component 3 may be a single waterproof ring, each waterproof ring capable of encircling the camera assembly 21 at least once to completely seal the camera assembly 21 with the hollow channel 11 in the circumferential direction, thereby improving waterproof performance. Alternatively, the waterproof component 3 may include multiple waterproof strips, and these multiple protective strips may cooperate to encircle the camera assembly 21 at least once. Of course, in some embodiments, the waterproof component 3 may include both waterproof rings and waterproof strips, as described above, and will not be repeated here.

[0055] Based on the technical solution disclosed herein, since the camera assembly 21 needs to reciprocate relative to the hollow channel 11 under the action of the driving component 22, and in order to ensure that the camera assembly 21 can slide smoothly inside the hollow channel, there will always be a very small gap between the hollow channel 11 and the camera assembly 21. Therefore, the existence of this very small gap will reduce the accuracy of the hollow channel 11 in guiding the camera assembly 21. Therefore, as... Figures 5-7 As shown, the camera assembly 21 in this application may further include a camera body 211 and a camera bracket 212 for fixing the camera body 211. The camera bracket 212 may include a slide rail 2121, and the housing 1 may include a guide groove 13 that cooperates with the slide rail 2121. Through the cooperation between the guide groove 13 and the slide rail 2121, the movement of the camera assembly 21 is limited, thereby improving the movement accuracy of the camera assembly 21.

[0056] In this embodiment, the housing 1 may include a base plate 14 and a limiting portion 15 extending upward from the base plate 14. The limiting portion 15 cooperates with the base plate 14 to form a guide groove 13. A slide rail 2121 extends outward from the surface of the camera bracket 212 toward the guide groove 13. The slide rail 2121 can be fitted into the interior of the guide groove 13 and cooperates with the guide groove 13 to guide the camera assembly 21. Wherein, as Figure 7 , Figure 8As shown, the housing 1 includes a single guide groove 13 located on one side of the camera bracket 212, and a single slide rail 2121 can be formed on the corresponding camera bracket 212. Alternatively, in some other embodiments, the housing 1 may also include multiple guide grooves 13, which may be distributed on both sides of the camera bracket 212, and at least two of the multiple guide grooves 13 cooperate with the corresponding slide rails to form at least two sets of mutually cooperating guide grooves 13 and slide rails 2121, thereby improving the stability of the sliding of the camera assembly 21.

[0057] In the above embodiments, the electronic device 100 may further include a lubricant 4 located within a guide groove 13 that mates with the slide rail 2121. When the slide rail 2121 slides relative to the guide groove 13, the lubricating effect of the lubricant 4 reduces the friction generated when the slide rail 2121 slides relative to the guide groove 13, thereby improving the smoothness of the camera assembly 21's movement. The lubricant 4 may be made of POM (polyformaldehyde) material, or other materials with self-lubricating properties.

[0058] In the above embodiments, such as Figure 9 As shown in Figure 10, the drive assembly 22 may include a lead screw structure 221 and a drive body 222. The lead screw structure 221 is connected to the power output shaft of the drive body 222. The drive body 222 may include a motor 2221, and the power output shaft may be mounted on the motor 2221. Alternatively, in order to increase the output torque of the drive body 222 and increase the force exerted by the drive body 222 on the lead screw structure 221, the drive body 222 in this disclosure may also include a gearbox 2222 connected to the motor 2221, and the power output shaft may be mounted on the gearbox 2222.

[0059] The motor 2221 can include one of a servo motor, a stepper motor, or an asynchronous motor. Taking a stepper motor as an example, when the stepper motor is in normal operation, it can rotate by the same angular displacement for each pulse signal it receives. Therefore, the rotation angle of the stepper motor can be obtained by counting the number of pulse signals received. Furthermore, the displacement of the lead screw structure 221 can be obtained through the transmission ratio within the gearbox 2222 and the transmission ratio of the transmission structure. Furthermore, the speed and acceleration of the stepper motor can be adjusted by regulating the frequency of the pulse signals, thereby achieving the purpose of adjusting the moving speed of the camera assembly 21.

[0060] The gearbox 2222 may include a single-stage reduction gearbox or a multi-stage reduction gearbox. The gearbox 2222 may include a sun gear, planet gears, planet carriers, a ring gear, etc. The sun gear is the driving gear and is connected to the shaft of the motor 2221, driving the planet gears to rotate.

[0061] In this embodiment, the power output shaft of the drive body 222 can cooperate with the lead screw structure 221 to drive the lead screw structure 221 to translate, thereby further pushing the camera assembly 21 to slide relative to the housing 101. The lead screw structure 221 will be described exemplarily below.

[0062] In one embodiment, still using Figure 9 As shown, the lead screw structure 221 may include a lead screw body 2211 and a stroke push rod 2212. The lead screw body 2211 can be connected to the power output shaft on the gearbox 2222, and the stroke push rod 2212 can be rotatably connected to the lead screw body 2211 and can be connected to the camera assembly 21. Therefore, when the lead screw body 2211 rotates, it drives the stroke push rod 2212 to translate. Under the action of the stroke push rod 2212, the camera assembly 21 translates relative to the housing 1, causing it to move relative to the housing 1 from... Figure 10 The status shown has switched to the following: Figure 9 The state shown. Of course, in some other embodiments, it can also be from... Figure 9 The status shown has switched to Figure 10 The state shown is as follows. The lead screw body 2211 may include a threaded rod-shaped structure, one end of the stroke push rod 2212 is threadedly connected to the lead screw body 2211, and the other end is connected to the camera bracket 212.

[0063] In the above embodiments, in order to optimize the force transmission between the camera assembly 211 and the lead screw body 2211, the following is still used: Figure 9 As shown, the camera module 2 may also include an elastic element 23, one end of which is fixed to the camera assembly 21 and the other end to the lead screw structure 221, specifically connected to the travel push rod 2212 included in the lead screw structure 221. Thus, when the drive body 222 operates, the lead screw body 2211 rotates, and the travel push rod 2212 translates, transmitting the force to the camera assembly 21 through the elastic element 23, driving the camera assembly 21 to translate. Based on the elastic element 23, when the user manually operates... Figure 9 When the camera module 100 or electronic device in the indicated state is dropped, the force generated by the camera module 100 is applied to the elastic element 23, which can be partially absorbed by the elastic element 23. This prevents the force from being directly transmitted to the travel push rod 2212, causing the travel push rod 2212 to move and the drive body 222 to reverse, resulting in damage.

[0064] The elastic element 23 can be fixed to the camera bracket 212 included in the camera assembly 21 by welding, or it can be fixed to the travel push rod 2212 by welding. The elastic element 23 can include silicone, plastic, latex, etc., or it can also include a spring, such as a tension spring or a compression spring, or other springs that transmit radial force, which will not be described in detail here.

[0065] In the technical solution disclosed herein, since the camera assembly 21 can move relative to the housing 1, in order to avoid the camera assembly 21 colliding with the housing 1, the displacement of the camera assembly 21 also needs to be limited in this disclosure.

[0066] In one embodiment, the movement of the camera assembly 21 can be controlled by switching the operating state of the drive component 22. Specifically, the camera assembly 21 may further include a Hall magnet 213 and a Hall chip 214. The Hall magnet 213 may be located on the camera bracket 212 and can move with the camera bracket 212. The Hall chip 214 can be fixed relative to the housing 1 and electrically connected to the controller of the electronic device 100. For example, the Hall chip 214 and the controller may be simultaneously mounted on the motherboard of the electronic device, and the Hall chip 214 and the controller may be connected via a spring contact or other means.

[0067] When the Hall magnet 213 moves with the camera bracket 212 to interact with the Hall chip 214, the Hall chip 214 is triggered and sends a generated status signal to the controller. This status signal can be used to characterize the relative positional relationship between the camera assembly 21 and the housing 1. For example, the controller determines, based on the received status signal, that the camera assembly 21 is currently extending out of the housing 1, i.e., the camera assembly 21 is in a position... Figure 9 In the aforementioned state, a control command can be sent to the drive component 22, which can then stop power output, decelerate, or accelerate according to the control command; alternatively, the controller determines, based on the received status signal, that the camera component 21 is currently housed inside the housing 1, i.e., in the aforementioned state. Figure 10 When the state shown can be displayed, a control command can be sent to the drive component 22, and the drive component 22 can stop power output, decelerate, or accelerate according to the control command.

[0068] The position of the Hall magnet 213 when the camera assembly 21 is extended relative to the housing 1 is different from the position when the camera assembly 21 is retracted relative to the housing 1. Therefore, the Hall chip in this technical solution may include a first Hall chip 2141 and a second Hall chip 2142. Both the first Hall chip 2141 and the second Hall chip 2142 can interact with the Hall magnet 213. The state signal generated when the first Hall chip 2141 interacts with the Hall magnet 213 is different from the state signal generated when the second Hall chip 2142 interacts with the Hall magnet 213, so that the electronic device can determine whether the camera assembly 21 is currently extended or retracted relative to the housing 1.

[0069] For example, the state signal generated when the first Hall chip 2141 interacts with the Hall magnet 213 can have a flag "0", and the indication signal generated when the second Hall chip 2142 interacts with the Hall magnet 213 can have a flag "1". Then, the electronic device can determine whether the camera assembly 21 is in an extended or retracted state based on the recognized flags.

[0070] In another embodiment, such as Figure 9 As shown, the translation of the camera assembly 21 can also be limited by mechanical contact. Specifically, the camera module 2 may also include a stop structure 24 fixed relative to the housing 1. When the stop structure 24 is in contact with the camera assembly 21, it can prevent the camera assembly 21 from moving further.

[0071] In this embodiment, as Figure 9 As shown, the camera assembly 21 can automatically Figure 9 The upward direction moves downward as shown, as Figure 10 As shown, the camera assembly 21 can automatically Figure 10 The downward movement is shown in the diagram. Therefore, in the technical solution of this disclosure, the stop structure 24 may include a first stop structure 241 and a second stop structure 242, wherein the first stop structure 241 may be located on the camera assembly 21. Figure 9 When the camera moves from top to bottom (i.e., in the first direction), the limiting and second stopping structures 242 can be used by the camera assembly 21. Figure 10 The movement is limited when moving from bottom to top (i.e., in the second direction).

[0072] Specifically, the first stop structure 241 can be fixed relative to the housing 1. When the camera assembly 21 moves downward under the action of the driving assembly 22 until it contacts the first stop structure 241, it is considered that the camera assembly 21 is completely housed inside the housing 1, and the first stop structure 241 restricts its further downward movement. Figure 9As shown, the first stop structure 241 may be directly fixed on the housing 1, or it may be fixed on the drive bracket of the drive assembly 22 that is fixedly connected to the housing 1. This disclosure does not limit this.

[0073] The second stop structure 242 can be fixed relative to the housing 1. When the camera assembly 21 moves upward under the action of the drive assembly 22 until it contacts the second stop structure 242, it is considered that the lens in the camera assembly 21 has completely extended out of the end face of the housing 1, and the second stop structure 242 can restrict its further upward movement. The second stop structure 242 can be directly fixed to the housing 1 or fixed to other fixed brackets.

[0074] Alternatively, the second stop structure 242 can be located on the hollow channel 11, specifically, as follows: Figure 9 , Figure 10 As shown, the second stop structure 242 may include the end face of the hollow channel 11, and the camera assembly 21 may include a stop screw located on the camera bracket 212. When the camera assembly 21 is... Figure 9 When the camera assembly 21 moves from bottom to top until the stop screw contacts the end face of the hollow channel 11, the end face can limit further upward movement of the camera assembly 21. Specifically, the end face of the hollow channel 11 can be configured to fit the stop screw.

[0075] Furthermore, since the stop structure 24 needs to contact the moving camera assembly 21, a certain force will inevitably be generated between them. Therefore, in order to reduce the force between the stop structure 24 and the camera assembly 21 and protect both the stop structure 24 and the camera assembly 21, the stop structure 24 in this disclosure may also include a buffer pad (not shown in the figure). This buffer pad can contact the camera assembly 21 to buffer the force between the stop structure and the camera, reduce collisions, and extend the service life of both the camera assembly 21 and the stop structure 24.

[0076] In another embodiment, the movement of the camera assembly 21 can be limited either by switching the operating state of the drive assembly 22 or by the mechanical contact between the stop structure 24 and the camera assembly 21. Therefore, after the drive assembly 22 switches its operating state, if the stroke push rod 2212 continues to act on the camera assembly 21 due to inertia, the stop structure 24 can be used to prevent the camera assembly 21 from continuing to move towards the outside or inside of the housing 1.

[0077] In the above embodiments, such as Figure 9 As shown, the second stop structure 242 can limit Figure 9The central camera component 21 moves from bottom to top, as... Figure 10 As shown, the first stop structure 241 can limit Figure 10 The movement is from top to bottom. In other words, in the technical solution disclosed herein, the maximum sliding displacement S1 of the camera assembly 21 can be limited by the first stop structure 241 and the second stop structure 242. That is, the camera assembly 21 can reciprocate relative to the housing 1 between a first position (the position where the first stop structure 241 is located) and a second position (the position where the second stop structure 242 is located), and the travel between the first position and the second position, i.e., the maximum sliding displacement S1 of the camera assembly 21, is less than the preset travel S2 of the lead screw structure 221.

[0078] The preset stroke S2 ​​can be represented as the displacement of the stroke push rod 2212 included in the lead screw structure 221, and this preset stroke is related to the drive signal received by the drive body 222. The relationship between the preset stroke and the drive signal received by the drive body 222 can be understood as follows: the controller of the electronic device can send a number of preset drive signals to the drive assembly 22, and the drive assembly 22 can drive the power output shaft to rotate a corresponding number of revolutions based on these drive signals. When the number of drive signals is determined, the number of revolutions of the power output shaft is determined, and based on the transmission relationship between the lead screw structure 221 and the power output shaft, the displacement of the stroke push rod 2212 can be determined, thus obtaining the determined preset stroke.

[0079] In this embodiment, the preset stroke of the lead screw structure 221 is greater than the stroke of the camera assembly 21 between the first and second positions. This ensures that the camera assembly 21 can slide to the first or second position under the drive of the drive assembly 22, and also prevents the drive assembly 22 from jamming. Specifically, the difference between the stroke between the first and second positions and the preset stroke can be within 0.2-0.5mm. This avoids the drive body 222 continuously outputting power when the camera assembly 21 is already limited by the stop structure 24, which would waste resources and easily damage the drive body.
