[0049] The present application provides a camera assembly, which makes the camera usage posture more diverse, thereby well meeting people's diverse usage needs. On the other hand, the present application also provides an electronic device having the above camera assembly.

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] like Figure 1 As shown, the electronic device 2 provided in the embodiment of the present application includes a body and a camera assembly 1. The electronic device 2 can be various types of electronic devices, such as electronic devices with display screens such as laptops, tablet computers, mobile phones, and learning machines, or electronic devices such as projectors that display images with the help of external supporting equipment (such as screens, etc.). This application takes a tablet computer as an example to embody the electronic device 2 in the attached drawings. Figure 1 An exemplary use state of the electronic device 2 is shown, with the front of the electronic device 2 (i.e., the side where the display screen is located) facing the user, and the electronic device 2 standing on the desktop 3 in front of the user. For example, when a student uses the electronic device 2 for online learning at home, the electronic device 2 stands on the desktop 3 to view the content on the display screen. It should be noted that in order to show the camera assembly 1 inside the electronic device 2, the drawings of this application have made the body of the electronic device 2 (including the display screen) transparent, which is only for the convenience of showing the structure, and this application does not specifically limit the body of the electronic device 2 to be transparent.

[0052] Figure 2 to Figure 4 Three postures of the camera assembly 1 are shown, among which, Figure 2 is an initial posture. In the initial posture, the camera assembly 1 is entirely located inside the body of the electronic device 2 , that is, the camera assembly 1 is not exposed outside the electronic device 2 . Figure 3 This is the first shooting posture. In the first shooting posture, part of the camera assembly 1 is exposed outside the electronic device 2. This part has a camera, so shooting can be performed. For example, this part can perform translational movement relative to the electronic device 2 to achieve a lifting function. When the shooting function needs to be used, this part rises to expose the camera. Figure 4The second shooting posture is a second shooting posture. In the second shooting posture, the above-mentioned local first part is flipped relative to the second part to be tilted, that is, the camera on the second part maintains the same shooting direction as in the first shooting posture in the second shooting posture, but the shooting direction of the camera on the first part in the second shooting posture is different from its shooting direction in the first shooting posture, for example, from horizontal shooting to overhead shooting.

[0053] Specifically, Figure 5 As shown, the camera assembly 1 includes: a first moving component 11, having a first sliding fit structure, and provided with a first camera; a first driving device 13, used to drive the first moving component 11 to translate along a first straight line; a second moving component 12, which is provided on the first moving component 11, has a second sliding fit structure, and is provided with a second camera; a second driving device 14, used to drive the second moving component 12 to move relative to the first moving component 11. The second moving component 12, driven by the second driving device 14, can tilt and flip relative to the first straight line based on the sliding fit of the first sliding fit structure and the second sliding fit structure, so as to change the shooting direction of the second camera. Figure 2 As shown, each of the first moving component 11 and the second moving component 12 is provided with at least one camera 15, that is, the camera assembly 1 includes at least two cameras 15. When the shooting function is required, the first moving component 11 is driven by the first driving device 13 to rise so that the camera 15 is exposed outside the body of the electronic device 2. Since the second moving component 12 is provided on the first moving component 11, the second moving component 12 rises together with the first moving component 11, so the camera 15 on the second moving component 12 is also exposed outside the body of the electronic device 2, as shown in FIG. Figure 3 As shown, at this time, all cameras 15 remain connected Figure 2 The same shooting direction as in the initial posture shown in FIG. 1 , for example, in this embodiment, the first straight line is parallel to the display screen of the electronic device 2, and the camera 15 is in Figure 3 In order to enrich the functions of the camera assembly 1, the camera 15 (i.e., the first camera) on the first moving part 11 in this embodiment includes a front camera and a rear camera arranged in opposite directions, wherein the front camera can be used to shoot the user facing the display screen. In this embodiment, the camera 15 (i.e., the second camera) on the second moving part 12 is mainly used to realize the overhead shooting function, but it is Figure 3 In the second posture shown, the second moving part 12 is still in the horizontal shooting direction. Based on the second posture, the second moving part 12 is driven by the second driving device 14 to tilt and flip relative to the first straight line based on the sliding cooperation of the first sliding cooperation structure and the second sliding cooperation structure, and finally presents Figure 4In the third posture shown, in the third posture, the camera 15 on the second moving part 12 can capture the content on the desktop 3 (such as a textbook placed on the desktop 3), and the camera 15 on the first moving part 11 is still in the horizontal shooting direction at this time, that is, the camera assembly 1 can achieve horizontal shooting and overhead shooting at the same time in the third posture. In summary, the camera assembly provided by the present application makes the camera usage posture more diverse, thereby well meeting people's diverse usage needs.

[0054] Specifically, in this embodiment, the second moving component 12 is hinged with the second driving device 14, and the second driving device 14 applies a driving force parallel to the first straight line to the second moving component 12. The sliding cooperation of the first sliding cooperation structure and the second sliding cooperation structure has a certain guiding effect on the motion trajectory of the second moving component 12 under this driving force, so as to realize the tilting and flipping of the second moving component 12 relative to the first straight line. In other words, in this embodiment, the second moving component 12 is driven to flip by the push-pull force along the straight line, so that the structural form of the second driving device 14 can be selected more flexibly.

[0055] In order to make the flipping movement of the second moving part 12 smoother, the present application preferably makes the first sliding matching structure a slide groove, and the second sliding matching structure is a cylinder located in the slide groove. More preferably, the slide groove includes a first groove and a second groove, and the cylinder includes a first column located in the first groove and a second column located in the second groove, and the first column and the second column are located on both sides of the hinge axis of the second moving part and the second driving device, so that the stability of the movement of the second moving part 12 can be improved and the shaking can be reduced.

[0056] In order to facilitate calculation of the extension trajectory of the first groove and the second groove and to facilitate manufacturing, the present application preferably makes one of the first groove and the second groove a straight groove extending along a straight line, and the other a curved groove extending along a curve. Figure 7 and Fig.10 As shown, in this embodiment, the first sliding matching structure on the first moving component 11 includes a straight slide groove 115 and a curved slide groove 116, and the second sliding matching structure on the second moving component 12 includes an upper ear shaft 124 (i.e., a first column) matched with the straight slide groove 115 and a lower ear shaft 125 (i.e., a second column) matched with the curved slide groove 116, the upper ear shaft 124 and the lower ear shaft 125 are parallel, and the hinge axis of the second moving component 12 and the second driving device 14 is located between the upper ear shaft 124 and the lower ear shaft 125 and is parallel to the upper ear shaft 124. In order to facilitate understanding of the movement principle of the second moving component 12, the following is based on FIG. 7 and FIG. Fig.10 The directions in the drawings are described in detail, that is, the directions such as "upper", "lower", "left", "right" and the like involved in the description are relative to the drawing direction of the drawings. Figure 7 and Fig.10In the figure, the first straight line is in the up-down direction, that is, the second driving device 14 applies a vertical force to the second moving part 12. In the initial posture, the upper ear shaft 124 is located at the left end of the straight slide groove 115, and the lower ear shaft 125 is located at the right end of the curved slide groove 116. Then, the second driving device 14 applies an upward driving force at the hinge between it and the second moving part 12. Under the action of this driving force, this hinge axis only moves up and down, and there is no left-right movement. However, as this hinge axis gradually rises, the upper ear shaft 124 slides to the right along the straight slide groove 115, and at the same time, the lower ear shaft 125 slides to the left along the curved slide groove 116. Since the curved slide groove 116 bends and extends to the upper left direction, the lower ear shaft 125 moves upward while moving to the left. In this embodiment, the extension direction of the straight slide groove 115 is perpendicular to the first straight line, so the upper ear shaft 124 does not move upward. Through analysis, it can be seen that the second moving part 12 flips to the right relative to the first moving part 11 with the non-fixed axis as the rotation center.

[0057] It should be noted that when making the straight slide groove 115 and the curved slide groove 116, the extension track of the curved slide groove 116 is determined by the extension track of the straight slide groove 115 and the distance from the above-mentioned hinge axis to the upper ear axis 124 and the lower ear axis 125. That is, when the extension track of the straight slide groove 115 (i.e., the motion track of the upper ear axis 124), the distance from the above-mentioned hinge axis to the upper ear axis 124, and the distance from the above-mentioned hinge axis to the lower ear axis 125 are all known, since the motion track of the above-mentioned hinge axis is determined, the extension track of the curved slide groove 116 (i.e., the motion track of the lower ear axis 125) can be calculated through the knowledge of plane geometry. In addition, in other embodiments, the straight slide groove 115 can also be slightly at a certain angle with the horizontal direction, that is, the straight slide groove 115 can be approximately perpendicular to the above-mentioned first straight line, which is conducive to avoiding the occurrence of a dead point position in motion. Of course, other measures can be taken to avoid the occurrence of a dead point position, such as setting the left end of the straight slide groove 115 to have a certain arc, or setting the upper ear shaft 124 from Fig.10 The position in the middle is moved a little to the right, and when setting the lower trunnion 125, it is moved from Fig.10 The position in the middle is moved a little to the left, that is, the upper trunnion 124, the hinge axis and the lower trunnion 125 are no longer as Fig.10 They are not arranged in the vertical direction, but are arranged at a certain angle to the vertical direction.

[0058] like Figure 8As shown, in order to realize the hinge connection between the second drive device 14 and the second moving component 12, in this embodiment, the second moving component 12 has a central shaft 121 and a rotation-limiting structure 122. The rotation-limiting structure 122 can be, for example, a non-circular hole. Both ends of the central shaft 121 are assembled into the rotation-limiting structure 122 to be restricted from rotating. The central shaft 121 is equipped with a bearing 123 connected to the second drive device 14, so that the second drive device 14 is hinged to the second moving component 12. Of course, in other embodiments, the rotation-limiting structure 122 can also be changed to a rotation matching structure, and the central shaft 121 can be fixedly connected to the second drive device 14, so that the second drive device 14 can be hinged to the second moving component 12.

[0059] like Figure 6 As shown, in this embodiment, the first driving device 13 includes: a first motor 131, the output shaft of the first motor 131 is provided with a first driving gear 132; a first rack 134, arranged parallel to the first straight line and fixed to the first moving component 11, and the first rack 134 is connected to the first driving gear 132 through a crown gear 133. It is easy to understand that the provision of the crown gear 133 can play a role in reducing speed and increasing torque, so that the first motor 131 with a relatively small power can be used for driving. Moreover, the crown gear 133 has a redirecting effect, that is, the relative position relationship between the first motor 131 and the first rack 134 can be adjusted by providing the crown gear 133. Of course, without considering factors such as the power of the first motor 131 and the specific arrangement angle, the first rack 134 and the first driving gear 132 can also be directly meshed, that is, the crown gear 133 is omitted.

[0060] like Figure 2 and Figure 6As shown, in order to make the first moving part 11 better translate along the first straight line, the first moving part 11 is provided with a slide bar 113 in this embodiment, which is arranged parallel to the first straight line and slides with the second limit slide groove 23 on the electronic device 2. In order to better limit the movement stroke of the first moving part 11, the first moving part 11 is provided with a baffle 111 in this embodiment. Specifically, there can be two baffles 111, which are symmetrically arranged on both sides of the first moving part 11. The first moving part 11 stops when the baffle 111 contacts the upper limit stop structure 21 on the electronic device 2 when it rises, and stops when the first moving part 11 descends to contact the slide bar 113 and the slide bar stop structure 24 on the electronic device 2, and the lower end of the first moving part 11 contacts the lower limit stop structure on the electronic device 2. In this embodiment, the electronic device 2 includes a position sensor arranged on the body, and the position sensor is used to detect the relative position of the first moving part 11 and the body. Specifically, the position sensor includes a magnet 112 fixed to the baffle 111 and a Hall element 22 fixed to the body of the electronic device 2. Of course, the position sensor may also be of other types, such as a contact position sensor.

[0061] like Figure 2 and Figure 8 As shown, in this embodiment, the second driving device 14 includes: a second motor 141, fixed to the first moving part 11, and the output shaft of the second motor 141 is provided with a second driving gear 142; a second rack, arranged parallel to the first straight line and hinged to the second moving part 12, and the second rack is directly meshed with the second driving gear 142. Of course, in other embodiments, the second rack and the second driving gear 142 can also be connected through a crown gear transmission, and the specific arrangement structure can refer to the setting of the first driving device 13. In order to make the second rack better translate in a direction parallel to the first straight line to ensure the direction of the driving force applied by the second driving device 14 to the second moving part 12 is stable, in this embodiment, the second rack has a guide bar 143, which extends in a direction parallel to the first straight line and slides with the first limiting slide groove 114 on the first moving part 11.

[0062] like Figure 2 and Figure 4 As shown, in this embodiment, the first moving component 11 has a receiving groove extending in a direction parallel to the first straight line, and the second moving component 12 is arranged in this receiving groove, so that the overall structure of the camera assembly 1 can be more compact. When the second moving component 12 is not flipped outward, the second moving component 12 is received in the receiving groove of the first moving component 11.

[0063] The present application also provides a control method, which is applied to the above electronic device 2, including:

[0064] When the instruction to enable the shooting function is obtained, the first driving device 13 is controlled to move the first moving component 11 to the end of the translation stroke;

[0065] When the instruction to disable the shooting function is obtained, the first camera and the second camera are turned off, and the position information of the second moving part 12 is detected. If the second moving part 12 is at the beginning of the flipping stroke relative to the first moving part 11, step A1 is entered, otherwise step A2 is entered.

[0066] Wherein, in step A1, the first driving device 13 is controlled to move the first moving component 11 to the starting end of the translation stroke;

[0067] Step A2, controlling the second driving device 14 to flip the second moving component 12 to the beginning of the flipping stroke, and then entering step A1.

[0068] After the electronic device 2 is powered on (or started), it enters a standby state. When the user needs to use the shooting function of the electronic device 2, the user can operate the electronic device 2 by, for example, clicking a virtual button, clicking an application software icon, pressing a physical button, or voice input, and the controller of the electronic device 2 can obtain an instruction to enable the shooting function. When the user finishes using the shooting function of the electronic device 2, the user can operate the electronic device 2 by, for example, clicking a virtual button, pressing a physical button, or voice input, and the controller of the electronic device 2 can obtain an instruction to disable the shooting function.

[0069] When the instruction to disable the shooting function is obtained, the first camera and the second camera are first turned off, and then the position information of the second moving part 12 is detected, and this position information is used as a condition for determining whether the first driving device 13 can be operated. This position information refers to the relative position relationship between the second moving part 12 and the first moving part 11. As mentioned above, the second moving part 12 can be flipped relative to the first moving part 11 under the drive of the second driving device 14, so there is a flipping stroke between the second moving part 12 and the first moving part 11. In the initial state (for example, the standby state after the electronic device 2 is powered on), the second moving part 12 is located at the beginning of this flipping stroke. Before the first driving device 13 is activated, it should be ensured that the second moving part 12 is located at the beginning of the flipping stroke. If the second moving part 12 is not at the beginning of the flipping stroke, such as the case where the user uses the overhead shooting function described later, the second driving device 14 is activated first to flip the second moving part 12 to the beginning of the flipping stroke, and then the first driving device 13 is activated to move the first moving part 11 to the beginning of the translation stroke. As mentioned above, the first moving component 11 can be driven by the first driving device 13 to translate along the first straight line relative to the body of the electronic device 2, so there is a translation stroke between the first moving component 11 and the body. In the initial state (for example, the standby state after the electronic device 2 is powered on), the first moving component 11 is located at the beginning of this translation stroke. That is to say, after the user finishes using the shooting function of the electronic device 2, the first moving component 11 and the second moving component 12 all return to their respective initial states, thereby preparing for the user to use the shooting function next time.

[0070] When the instruction to enable the shooting function is obtained, the first driving device 13 is controlled to move the first moving part 11 to the end of the above-mentioned translation stroke, that is, the first moving part 11 moves a certain distance relative to the body of the electronic device 2 along the aforementioned first straight line from the position of the initial state, so as to prepare for the normal use of the first camera and the second camera in the next step. For example, in the initial state, the first camera and the second camera are hidden inside the body of the electronic device 2, and when the first moving part 11 is at the end of the above-mentioned translation stroke, the first camera and the second camera move to the outside of the body and are exposed, so that the user can use the first camera and the second camera to complete the desired shooting. Specifically, the user can control the first camera and the second camera to open respectively, that is, the user can select the camera to be used. For example, the first camera is mainly responsible for horizontal shooting, and the second camera is mainly responsible for overhead shooting. Then, when the user only needs to shoot horizontally, only the first camera can be turned on.

[0071] The control method provided in the present application may further include: when obtaining a bird's-eye view instruction, controlling the second driving device 14 to flip the second moving part 12 toward the end of the flipping stroke. In other words, the bird's-eye view function of the electronic device 2 can be taken care of by the second camera. When the user needs to use the bird's-eye view function, the electronic device 2 can be operated by, for example, clicking a virtual button, pressing a physical button, or voice input, and the controller of the electronic device 2 can obtain the bird's-eye view instruction. It should be noted that before executing the bird's-eye view instruction, the controller has executed the aforementioned instruction to enable the shooting function, that is, the first moving part 11 is already at the end of the aforementioned translation stroke.

[0072] In a specific embodiment, when a command for shooting from below is obtained, the second driving device 14 is controlled to make the second moving part 12 flip to the end of the flipping stroke, that is, the second camera only completes the shooting from below function when the second moving part 12 is at the end of the flipping stroke. In a preferred embodiment, when a command for shooting from below is obtained, the second driving device 14 is controlled to make the second moving part 12 flip toward the end of the flipping stroke at a preset step angle, that is, the second camera can complete the shooting from below function when the second moving part 12 is at multiple different positions of the flipping stroke, that is, the second moving part 12 can stop at multiple different positions of the flipping stroke, so that the second camera can obtain multiple different shooting from below angles. For example, the above-mentioned flipping stroke is 45°, that is, the angle of rotation of the second moving component 12 relative to the first moving component 11 from the beginning to the end of the flipping stroke is 45°. Every time the user clicks the preset button, the controller of the electronic device 2 obtains a low-angle shooting instruction, and then controls the second driving device 14 to flip the second moving component 12 15° toward the end of the flipping stroke. In this way, three low-angle shooting postures can be obtained in which the second moving component 12 rotates 15°, 30° and 45° relative to the first moving component 11. In another preferred embodiment, when a low-angle shooting instruction is obtained, the second driving device 14 is controlled to flip the second moving component 12 toward the end direction of the flipping stroke until the duration of the above-mentioned low-angle shooting instruction ends, that is, the second moving component 12 can stop at any position of the flipping stroke, and the user can select the low-angle shooting posture of the electronic device 2 by controlling the duration of the low-angle shooting instruction. For example, the user continues to press and hold the preset button, and the controller of the electronic device 2 obtains the low-angle shooting instruction and controls the second driving device 14 to flip the second moving component 12 toward the end direction of the flipping stroke until it detects that the above-mentioned preset button is in an unpressed state (that is, the user releases the preset button), and then stops the rotation of the second moving component 12.
