Fig. 1 is a first schematic structural diagram of an electronic device 100 according to an exemplary embodiment, fig. 2 is a second schematic structural diagram of the electronic device 100 according to an exemplary embodiment, and fig. 3 is a schematic structural diagram of a camera module 2 according to an exemplary embodiment. As shown in fig. 1 to 3, 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 formed by extending inward from a surface of the housing, and the hollow channel 11 may communicate with the outside through an opening 12 formed in the housing 1.

The camera module 2 may include a camera assembly 21 and a driving assembly 22 engaged with the camera assembly 21. The camera assembly 21 can be disposed through the hollow passage 11 and can reciprocate relative to the hollow passage 11 under the driving of the driving assembly 22. Therefore, when a user needs to take a picture by using the camera module 2, the camera module 21 can be controlled to extend out of the housing 1 through the opening 12, so that the state shown in fig. 1 is switched to the state shown in fig. 2; when the photographing requirement is not met, the electronic device 100 is controlled to retract into the electronic device 100, so that the front photographing function of the electronic device 100 is guaranteed, meanwhile, the display area of the electronic device 100 is prevented from being occupied, and the screen occupation ratio of the electronic device 100 is improved.

Further, as shown in fig. 3 and 4, the electronic device 100 may further include a waterproof member 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 a gap between the camera assembly 21 and the hollow channel 11 and prevent external liquid or vapor from entering the inside of the electronic device 100 through the opening 12.

According to the embodiment, the hollow channel 11 is formed by extending the shell 1 inwards in the disclosure, and the moving direction of the camera assembly 21 can be limited by the matching between the hollow channel 11 and the camera assembly 21, so that compared with a scheme of independently arranging a lantern ring in the related art, the assembly process is simplified, and the risk of losing accessories is reduced. Further, the waterproof member 3 located between the hollow passage 11 and the camera assembly 21 can partially fill up a gap that exists for smooth sliding of the camera assembly 21, thereby preventing external liquid or vapor from entering, and improving the waterproof level of the electronic apparatus 100.

It should be noted that: the interference between the flashing 3 and the hollow channel 11 and the camera assembly 21 may be represented by: when the flashing 3 is positioned between the camera assembly 21 and the hollow channel 11, the flashing 3 deforms under the influence of the camera assembly 21 or the hollow channel 11, since the thickness is greater than the gap between the hollow channel 11 and the camera assembly 21. Specifically, when the waterproof member 3 is fixedly attached to the camera assembly 21, the waterproof member 3 may interfere with the inner wall of the hollow passage 11; when the waterproof member 3 is fixedly attached to the inner wall of the hollow passage 11, the waterproof member 3 may interfere with the surface of the camera assembly 21.

In the present embodiment, assuming that the waterproof member 3 is attached to the surface of the camera assembly 21 and moves with the camera assembly 21, the hollow passage 11 may include a first fitting region 111 and a second fitting region 112 on the inner wall side. As shown in fig. 4, when the camera assembly 21 is at the first predetermined position, that is, when the camera assembly 21 is accommodated in the boundary position inside the electronic apparatus 100, the first fitting area 111 interferes with the waterproof member 3, so as to achieve the waterproof purpose. As shown in fig. 5, when the camera assembly 21 is in the second preset position, i.e. the camera assembly 21 extends to the outside of the electronic device 100, and is in another boundary position, the second fitting area 112 interferes with the waterproof member 3 to achieve the waterproof purpose. Based on this, whether the camera assembly 21 is inside the electronic apparatus 100 or the camera assembly 21 is outside the electronic apparatus 100, the waterproof member 3 and the hollow channel 11 can be engaged to prevent water.

Further, when waterproof member 3 is connected to camera head assembly 21, since the thickness of waterproof member 3 is greater than the gap between camera head assembly 21 and the inner wall of hollow channel 11, in order to avoid continuous interference between waterproof member 3 and the inner wall of hollow channel 11 during movement of camera head assembly 21, as shown in fig. 4 and 5, hollow channel 3 may further include an avoidance area 113 located between first fitting area 111 and second fitting area 112, where avoidance area 113 is offset to the outside of housing 1 relative to first fitting area 111 and second fitting area 112, so that waterproof member 3 is in a state of contacting or separating with the inner wall of hollow channel 3 when passing through avoidance area 113, which can reduce resistance of hollow channel 11 to movement of camera head assembly 21 and improve smoothness of movement of camera head assembly 21.

Wherein a smaller gap may exist between the first mating area 111 or the second mating area 112 and the surface of the camera head assembly 21 to improve the smoothness of the sliding of the camera head assembly 21. The gap may be between 0.05-0.1 mm; there may also be a gap between the avoidance region 113 and the surface of the camera head assembly 21 that is greater than the gap between the first mating region 111 or the second mating region 112 and the surface of the camera head assembly 21, for example, the gap between the avoidance region 113 and the surface of the camera head assembly 21 may be between 0.12mm and 0.25 mm. The length of the escape area 113 is related to the length of the hollow channel 11 and the distance between the first and

second mating areas

111, 112 and can be designed as desired.

In the above embodiments, the waterproof member 3 may be a single waterproof ring, and each waterproof ring can surround the camera assembly 21 at least once to completely seal the camera assembly 21 with the circumference of the hollow passage 11, thereby improving the waterproof performance. Alternatively, the flashing 3 may comprise a plurality of flashing strips and the plurality of strips may fit at least one turn around the camera assembly 21. Of course, in some embodiments, the waterproof member 3 may include a waterproof ring and a waterproof strip, which are specifically referred to above and will not be described herein again.

Based on the technical solution of the present disclosure, since the camera head assembly 21 needs to perform a reciprocating motion relative to the hollow channel 11 under the action of the driving assembly 22, in order to ensure that the camera head assembly 21 can smoothly slide in the hollow channel, a very small gap always exists between the hollow channel 11 and the camera head assembly 21. Therefore, the accuracy with which the hollow passageway 11 guides the camera head assembly 21 is reduced due to the presence of this very small gap. Therefore, as shown in fig. 5 to 7, in the present application, the camera assembly 21 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, the housing 1 may include a guide groove 13 matched with the slide rail 2121, and the guide groove 13 is matched with the slide rail 2121 to limit the movement of the camera assembly 21, so as to improve the movement accuracy of the camera assembly 21.

In this embodiment, the housing 1 may include a bottom plate 14, and a limiting portion 15 extending upward from the bottom plate 14, the limiting portion 15 and the bottom plate 14 cooperate to form a guide slot 13, the camera bracket 212 extends outward toward the surface of the guide slot 13 to form a slide rail 2121, and the slide rail 2121 may be fitted into the guide slot 13 to cooperate with the guide slot 13 to guide the camera assembly 21. As shown in fig. 7 and 8, the housing 1 includes a single guide groove 13, the single guide groove 13 is located at one side of the camera bracket 212, and a single slide rail 2121 may be formed on the corresponding camera bracket 212. Alternatively, in some other embodiments, the housing 1 may also include a plurality of guide grooves 13, the guide grooves 13 may be distributed on two sides of the camera bracket 212, and at least two of the guide grooves 13 cooperate with corresponding slide rails to form at least two sets of guide grooves 13 and slide rails 2121 cooperating with each other, so as to improve the sliding stability of the camera assembly 21.

In the above embodiments, the electronic device 100 may further include a lubricant member 4, and the lubricant member 4 is located in the guide groove 13 cooperating with the slide rail 2121. When the slide rail 2121 slides relative to the guide groove 13, the friction force generated when the slide rail 2121 slides relative to the guide groove 13 can be reduced by the lubricating action of the lubricating member 4, and the smoothness of the movement of the camera head assembly 21 can be improved. The lubricant 4 may be made of POM (polyoxymethylene) material, or may be made of other materials with self-lubricating property.

In the above embodiments, as shown in fig. 9 and 10, the driving assembly 22 may include the screw structure 221 and the driving body 222, the screw structure 221 is connected to the power output shaft of the driving body 222, the driving body 222 may include the motor 2221, and the power output shaft may be disposed on the motor 2221; alternatively, in order to increase the output torque of the driving body 222 and increase the acting force of the driving body 222 on the screw structure 221, the driving body 222 in the present disclosure may further include a gearbox 2222 connected to the motor 2221, and the power output shaft is disposed on the gearbox 2222.

The motor 2221 may include one of a servo motor, a stepping motor, and an asynchronous motor. Taking the example that the motor 2221 includes a stepping motor, when the stepping motor is in a normal operating state, the stepping motor can rotate by the same angular displacement every time it receives a pulse signal. Therefore, the rotation angle of the stepping motor can be obtained by counting the number of the pulse signals received by the stepping motor, and further, the displacement of the lead screw structure 221 can be obtained through the transmission ratio in the gearbox 2222 and the transmission ratio of the transmission structure. Further, the speed and acceleration of the stepping motor can be adjusted by adjusting the frequency of the pulse signal, so as to achieve the purpose of adjusting the moving speed of the camera assembly 21.

The gearbox 2222 may include a one-stage gearbox or a multi-stage gearbox. The transmission 2222 may include a sun gear, a planet carrier, a ring gear, etc. therein. The sun gear is a driving wheel connected with a rotating shaft of the motor 2221, and the planet gear is driven by the sun gear to rotate.

In this embodiment, the power output shaft of the driving body 222 can cooperate with the lead screw structure 221 to drive the lead screw structure 221 to translate so as to further push the camera head assembly 21 to slide relative to the housing 101. The following description will be made for an exemplary lead screw structure 221.

In an embodiment, also shown in fig. 9, the lead screw structure 221 can include a lead screw body 2211 and a travel push rod 2212. The lead screw main body 2211 can be connected with a power output shaft on the gearbox 2222, and the stroke push rod 2212 can be rotatably connected with the lead screw main body 2211 and can be connected with the camera assembly 21. Accordingly, when the lead screw main body 2211 rotates, the stroke rod 2212 is driven to translate, and the camera head assembly 21 translates with respect to the housing 1 by the stroke rod 2212, so that the state with respect to the housing 1 is switched from the state shown in fig. 10 to the state shown in fig. 9. Of course, in other embodiments, the state shown in fig. 9 may be switched to the state shown in fig. 10. The lead screw main body 2211 may include a rod-shaped structure with threads, and one end of the stroke push rod 2212 is connected to the lead screw main body 2211 by threads, and the other end is connected to the camera bracket 212.

In the above embodiments, in order to optimize the force transmission between the camera head assembly 211 and the lead screw main body 2211, as shown in fig. 9, the camera head module 2 may further include an elastic element 23, where one end of the elastic element 23 is fixed to the camera head assembly 21, and the other end of the elastic element 23 is fixed to the lead screw structure 221, and may be specifically connected to the stroke pushing rod 2212 included in the lead screw structure 221. Thus, when the driving body 222 operates, the lead screw body 2211 rotates, the stroke rod 2212 translates, and the elastic element 23 transmits an acting force to the camera assembly 21, so that the camera assembly 21 is driven to translate. Based on the elastic element 23, when the user manually operates the camera module 100 in the state shown in fig. 9, or the electronic device falls, the acting force generated by the camera module 100 acts on the elastic element 23 and can be partially absorbed by the elastic element 23, so that the acting force can be prevented from being directly transmitted to the stroke push rod 2212, the stroke push rod 2212 moves, and the driving body 222 rotates reversely to cause damage.

The elastic element 23 may be fixed to the camera head bracket 212 included in the camera head assembly 21 by welding, and may also be fixed to the stroke push rod 2212 by welding. The elastic element 23 may include a silicone part, a plastic part, a latex part, or the like, or the elastic element 23 may further include a spring, for example, an extension spring or a compression spring, or may also be another spring for transmitting radial force, which is not described in detail herein.

In the technical solution of the present disclosure, 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 needs to be limited in the present disclosure.

In one embodiment, the travel displacement of the camera head assembly 21 may be controlled by switching the operating state of the drive assembly 22. Specifically, the camera head assembly 21 may further include a hall magnet 213 and a hall chip 214, and the hall magnet 213 may be located on the camera head bracket 212 and may move with the movement of the camera head bracket 212. The hall chip 214 can be fixed relative to the housing 1 and electrically connected with a controller of the electronic device 100. For example, the hall chip 214 and the controller may be disposed on a main board of the electronic device at the same time, and the hall chip 214 and the controller may be electrically connected through a spring or in other forms.

When the hall magnet 213 interacts with the hall chip 214 along with the movement of the camera bracket 212, the hall chip 214 is triggered and sends a generated status signal to the control, and the status signal can be used for representing the current relative position relationship between the camera assembly 21 and the housing 1. For example, when the controller determines that the camera assembly 21 is currently extended out of the housing 1 according to the received status signal, that is, when the camera assembly 21 is in the state shown in fig. 9, the controller may send a control command to the driving assembly 22, and the driving assembly 22 may stop power output, or decelerate, or accelerate, etc. according to the control command; alternatively, when the controller determines that the camera assembly 21 is currently housed in the housing 1 based on the received state signal, that is, when the state is shown in fig. 10, the controller may transmit a control command to the driving assembly 22, and the driving assembly 22 may stop the power output, decelerate, accelerate, or the like based on the control command.

The position of the hall magnet 213 when the camera head assembly 21 is extended relative to the housing 1 is different from the position of the hall magnet 213 when the camera head assembly 21 is retracted relative to the housing 1. Therefore, the hall chips in the technical solution of the present disclosure 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 may interact with the hall magnet 213, and a state signal generated when the first hall chip 2141 interacts with the hall magnet 213 is different from a state signal generated when the second hall chip 2142 interacts with the hall magnet 213, so that the electronic device determines that the current camera assembly 21 is in the extended state or the retracted state with respect to the housing 1.

For example, the status signal generated when the first hall chip 2141 interacts with the hall magnet 213 may have the flag "0", and the indication signal generated when the second hall chip 2142 interacts with the hall magnet 213 may have the flag "1". Then, the electronic device may determine whether the camera assembly 21 is currently in the extended state or the retracted state based on the recognized identification.

In another embodiment, as shown in FIG. 9, the translation of the camera head assembly 21 may also be limited by mechanical contact. Specifically, the camera module 2 may further include a stop structure 24 fixed relative to the housing 1, and when the stop structure 24 is connected with the camera assembly 21, the camera assembly 21 may be prevented from further moving by the stop structure 24.

In the present embodiment, as shown in fig. 9, the camera assembly 21 can be moved downward from the upper side shown in fig. 9, and as shown in fig. 10, the camera assembly 21 can be moved upward from the lower side shown in fig. 10. Therefore, in the technical solution of the present disclosure, the stop structure 24 may include a first stop structure 241 and a second stop structure 242, where the first stop structure 241 may perform a limiting operation when the camera assembly 21 moves from top to bottom (i.e., the first direction) in fig. 9, and the second stop structure 242 may perform a limiting operation when the camera assembly 21 moves from bottom to top (i.e., the second direction) in fig. 10.

Specifically, the first stop structure 241 may be fixed relative to the housing 1, and when the camera head assembly 21 moves down to contact with the first stop structure 241 under the action of the driving assembly 22, it is considered that the camera head assembly 21 is completely accommodated in the housing 1, and the first stop structure 241 limits the camera head assembly from moving downward. As shown in fig. 9, the first stop structure 241 may be directly fixed to the housing 1, or may be fixed to a driving bracket included in the driving assembly 22 and fixedly connected to the housing 1, which is not limited in this disclosure.

The second stop structure 242 may be fixed relative to the housing 1, and when the camera head assembly 21 moves up under the action of the driving assembly 22 to be contacted by the second stop structure 242, that is, when the lens in the camera head assembly 21 is considered to be completely extended out of the end surface of the housing 1, the second stop structure 242 may limit the lens to move upwards. The second stop structure 242 may be directly fixed to the housing 1 or may be fixed to another fixing bracket.

Still alternatively, the second stop structure 242 may be located on the hollow channel 11, and specifically, as shown in fig. 9 and 10, the second stop structure 242 may include an end surface of the hollow channel 11, and the camera head assembly 21 may include a stop screw located on the camera head bracket 212. When the camera head assembly 21 is moved from the lower side to the upper side in fig. 9 until the stopper screw comes into contact with the end surface of the hollow passage 11, further upward movement of the camera head assembly 21 can be restricted by the end surface. In particular, the end face of the hollow channel 11 may be provided with a shape adapted to the stop screw.

Further, since the stop structure 24 needs to contact the moving camera head assembly 21, a certain force is inevitably generated between the two. Therefore, in order to reduce the force acting between the stopper structure 24 and the camera head assembly 21, the stopper structure 24 and the camera head assembly 21 are protected. The stopping structure 24 in the present disclosure may further include a buffer pad (not shown in the drawings), which may contact with the camera assembly 21, for buffering an acting force between the stopping structure and the camera, reducing a collision, and prolonging service lives of the camera assembly 21 and the stopping structure 24.

In yet another embodiment, the movement of the camera head assembly 21 can be limited by either switching the operating state of the drive assembly 22 or by mechanical contact between the stop structure 24 and the camera head assembly 21. Based on this, when the stroke push rod 2212 continues to act on the camera head assembly 21 due to inertia after the driving assembly 22 is switched to the operating state, the camera head assembly 21 can be prevented from continuing to move towards the outer side of the housing 1 or towards the inner side of the housing 1 by the limiting function of the stop structure 24.

In the above embodiments, as shown in fig. 9, the second stop structure 242 can limit the movement of the camera head assembly 21 from bottom to top in fig. 9, and as shown in fig. 10, the first stop structure 241 can limit the movement from top to bottom in fig. 10. In other words, in the solution of the present disclosure, the first stop structure 241 and the second stop structure 242 may define the maximum sliding displacement S1 of the camera head assembly 21. That is, the camera head assembly 21 is capable of reciprocating relative to the housing 1 between a first position (where the first stop structure 241 is located) and a second position (where the second stop structure 242 is located), where a stroke between the first position and the second position, i.e., a maximum sliding displacement S1 of the camera head assembly 21, is smaller than a preset stroke S2 of the lead screw structure 221.

The preset route S2 may be represented as: the lead screw structure 221 includes a stroke of displacement of the push rod 2212, and the preset stroke is related to the driving signal received by the driving body 222. The correlation of the preset stroke with the driving signal received by the driving body 222 can be understood as: the controller of the electronic device may send a plurality of preset driving signals to the driving component 22, and the driving component 22 may drive the power output shaft to rotate by a corresponding number of revolutions according to the plurality of driving signals. When the number of the driving signals is determined, the number of revolutions of the power output shaft is determined, and the moving displacement of the stroke push rod 2212 can be determined according to the transmission relation between the screw rod structure 221 and the power output shaft, that is, the determined preset stroke can be obtained.

In this embodiment, the preset stroke of the lead screw structure 221 is greater than the stroke of the camera head assembly 21 between the first position and the second position, so that on one hand, the camera head assembly 21 can be ensured to slide to the first position or the second position under the driving of the driving assembly 22, and on the other hand, the driving assembly 22 can be prevented from being jammed. Specifically, the difference between the stroke between the first position and the second position and the preset stroke may be within 0.2-0.5mm, which may avoid the situation that the camera assembly 21 has been limited by the stop structure 24, the driving body 222 continuously outputs power, which may cause resource waste, and may easily damage the driving body.
