[0052] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0053] The following is combined with Figures 1-9 The multifunctional camera module and electronic device provided by the utility model embodiments will be described in detail through specific implementation examples and application scenarios.

[0054] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a multi-functional camera module 1, including: a lifting drive component 11, a first camera module 12, a second camera module 13, and a guide component 14;

[0055] The first camera module 12 is configured to be located on the rear side of the device body 2 and has a rear camera state. The lifting drive 11 is connected to the first camera module 12 to drive the first camera module 12 to rise and fall relative to the device body 2.

[0056] The second camera module 13 is rotatably connected to the first camera module 12. The guide 14 is slidably engaged with the second camera module 13 and has a guide hole. During the process of the lifting drive 11 driving the first camera module 12 to rise, the guide hole of the guide 14 is used to guide the second camera module 13 to flip forward to the reading state.

[0057] It is understood that a groove is provided on the back of the device body 2, and the groove can be set close to the top edge of the device body 2. The first camera module 12 is movably set in the groove along the height direction of the device body 2. The lens of the first camera module 12 faces the rear side of the device body 2. The first camera module 12 is used to take an image of the target object on the rear side of the device body 2 in the rear camera state. The optical axis of the first camera module 12 can be configured to be perpendicular to the back of the device body 2.

[0058] like Figure 4 and Figure 5 As shown, a first hinge ear 1211 can be provided at the end of the first camera module 12 near the second camera module 13, and a second hinge ear 1311 can be provided at the end of the second camera module 13 near the first camera module 12. The first hinge ear 1211 and the second hinge ear 1311 are hinged by a pin to achieve a rotatable connection between the second camera module 13 and the first camera module 12. The first camera module 12 and the second camera module 13 are configured to be rotatably arranged along the length of the device body 2. See [reference needed]. Figure 3 .

[0059] Furthermore, the guide member 14 can be disposed on the same side of the first camera module 12 and the second camera module 13, or the guide member 14 can be disposed on both sides of the first camera module 12 and the second camera module 13. The guide member 14 can be provided with guide holes, and the guide member 14 slides in cooperation with the second camera module 13 through a guide structure.

[0060] When the first camera module 12 is in its initial state, that is, when the lifting drive 11 does not drive the first camera module 12 to rise, the first camera module 12 and the second camera module 13 can be arranged side by side on the rear side of the device body 2, and the second camera module 13 is located on the upper side of the first camera module 12. During the process of the lifting drive 11 driving the first camera module 12 to rise, the guide 14 will guide the second camera module 13 to flip towards the front side of the device body 2 through the guide hole until the second camera module 13 reaches the reading state.

[0061] The second camera module 13 is provided with at least a sliding structure that slides with the guide hole. According to the design requirements of the flipping posture of the second camera module 13, the guide path of the guide hole can be adapted to be set. For example, the guide hole can extend along a bent or arc-shaped guide path.

[0062] When the second camera module 13 is in the pointing-reading state, the lens of the second camera module 13 is tilted downwards toward the paper medium placed in front of the device body 2, so as to identify the content pointed to and read by the user on the paper medium. The lens of the second camera module 13 can be a fixed-focus lens or a zoom lens, and multiple lenses can be set for the second camera module 13, such as 2-3, without specific limitation.

[0063] The multifunctional camera module 1 shown in this utility model, by setting up a lifting drive 11, a first camera module 12, a second camera module 13 and a guide 14, allows the first camera module 12 to directly capture images of the target object behind the device body 2 in the rear camera state. When the finger reading function is required, since the first camera module 12 and the second camera module 13 are rotatably set, the second camera module 13 can be guided to rotate at a small angle by the guide hole of the guide 14 during the process of the lifting drive 11 driving the first camera module 12 to rise. This controls the second camera module 13 to rotate towards the front of the device body 2 to the finger reading state.

[0064] Therefore, the multifunctional camera module 1 of this utility model can realize the rear camera and finger reading functions respectively, realizing the diversification of functions. Compared with the existing single camera module design that flips from back to front, it also effectively reduces the movement space occupied by the second camera module 13 during the flipping to the finger reading state.

[0065] In some embodiments, such as Figure 1 and Figure 3 As shown, during the process of the lifting drive 11 driving the first camera module 12 to rise, the guide hole of the guide 14 is used to guide the second camera module 13 to rise to the front camera state first, and then flip forward to the finger reading state.

[0066] Understandably, when the lifting drive 11 drives the first camera module 12 to rise, a portion of the guide hole on the guide 14 will guide the second camera module 13 to rise together with the first camera module 12 until the lens of the second camera module 13 is located on the upper side of the top edge of the device body 2, that is, the top edge of the device body 2 will not obstruct the lens of the second camera module 13. At this time, the optical axis of the second camera module 13 can be perpendicular to the front side of the device body 2, so that the second camera module 13 is in a front-facing state.

[0067] Since the second camera module 13 and the first camera module 12 are rotatably connected, the extension direction of the guide hole on the guide member 14 can be set, that is, the other part of the guide hole can be used to control the flipping direction of the second camera module 13 relative to the first camera module 12, and guide the second camera module 13 to flip. In this way, as the lifting drive member 11 continues to drive the first camera module 12 to rise, the guide hole on the guide member 14 can be used to guide the second camera module 13 to rotate relative to the first camera module 12 and flip towards the front of the device body 2 until the second camera module 13 reaches the reading state.

[0068] Correspondingly, during the process of the lifting drive 11 driving the first camera module 12 to descend, the guide 14 will guide the second camera module 13 to switch from the finger reading state to the front camera state, which will not be described in detail.

[0069] In some embodiments, such as Figure 1 , Figure 4 and Figure 7 As shown, the guide hole of the guide member 14 includes a first guide hole 141. The side of the first camera module 12 is provided with a first connecting shaft 1201. The first connecting shaft 1201 is inserted into the first guide hole 141. The first guide hole 141 is used to guide the first camera module 12 to move up and down relative to the device body 2.

[0070] It is understood that the first guide hole 141 can be configured to extend along the height direction of the device body 2, and the first connecting shaft 1201 is movably disposed in the first guide hole 141 along the extension direction of the first guide hole 141. Based on the sliding fit between the first connecting shaft 1201 and the first guide hole 141, the first camera module 12 can be guided to rise and fall relative to the device body 2 by means of the first guide hole 141.

[0071] In practical applications, the first connecting shaft 1201 can be designed as a flat shaft. The thickness of the flat shaft is adapted to the opening width of the first guide hole 141. This design can ensure that the first connecting shaft 1201 can only move along the extension direction of the first guide hole 141 and will not rotate within the first guide hole 141, thereby ensuring the stability of the first camera module 12 relative to the device body 2 during lifting.

[0072] In some examples, the first connecting shaft 1201 is provided with a first wiring channel, which is used to lay out the signal leads of the relevant components of the first camera module 12.

[0073] In some examples, such as Figure 1 and Figure 4As shown, in order to further ensure the stability of the lifting and lowering of the first camera module 12 relative to the device body 2, two guide members 14 can be provided. The two guide members 14 are arranged opposite to each other on both sides of the first camera module 12. The first camera module 12 is provided with two first connecting shafts 1201. The two first connecting shafts 1201 are located on both sides of the first camera module 12 and are inserted into the corresponding first guide holes 141 of the two guide members 14.

[0074] In some embodiments, such as Figure 1 , Figure 5 and Figure 7 As shown, the guide hole of the guide member 14 also includes a second guide hole 142, and the side of the second camera module 13 is provided with a second connecting shaft 1301, which is rotatably inserted into the second guide hole 142.

[0075] The second guide hole 142 includes a first guide section 1421 and a second guide section 1422, which are connected. The first guide section 1421 is used to guide the second camera module 13 to rise and fall relative to the device body 2, and the second guide section 1422 is used to guide the second camera module 13 to flip relative to the device body 2.

[0076] It is understood that the first guide segment 1421 can be configured to extend along a first direction, and the second guide segment 1422 can be configured to extend along a second direction. The first direction is the height direction along the device body 2, and the angle between the first direction and the second direction can be an obtuse angle, for example, the angle between the first direction and the second direction is 100° to 145°.

[0077] To ensure the smooth movement of the second connecting shaft 1301 along the extension direction of the second guide hole 142, a bearing is rotatably provided on the second connecting shaft 1301, and the bearing is adapted to roll contact with the hole wall of the second guide hole 142.

[0078] For example, the bearing can be provided with an annular groove extending circumferentially, so that the bearing is formed as a U-shaped profile bearing. The shape of the U-shaped profile bearing is adapted to the shape of the hole wall of the second guide hole 142. This design can ensure that the second connecting shaft 1301 moves stably and reliably along the extension direction of the second guide hole 142, thereby ensuring the stability and reliability of the second camera module 13 flipping relative to the first camera module 12.

[0079] In some examples, the second connecting shaft 1301 is provided with a second wiring channel, which is used to lay out the signal leads of the relevant components of the second camera module 13.

[0080] In practical applications, when the lifting drive 11 drives the first camera module 12 to rise, the second connecting shaft 1301 will move in the first guide section 1421 along the extension direction of the first guide section 1421. Based on the sliding cooperation between the second connecting shaft 1301 and the first guide section 1421, the second camera module 13 will rise relative to the device body 2 until the second camera module 13 reaches the front-facing state.

[0081] As the lifting drive 11 continues to drive the first camera module 12 upward, due to the rotatable connection between the first camera module 12 and the second camera module 13, the second connecting shaft 1301 will rotate in the second guide section 1422 under the drive of the second camera module 13, and move along the extension direction of the second guide section 1422 toward the end of the second guide section 1422 away from the first guide section 1421. Based on the sliding fit between the second connecting shaft 1301 and the second guide section 1422, the second camera module 13 is guided by the second guide section 1422 to flip downward relative to the first camera module 12 toward the front side of the device body 2. When the second connecting shaft 1301 reaches the end of the second guide section 1422 away from the first guide section 1421, the flip angle of the second camera module 13 relative to the first camera module 12 reaches its maximum.

[0082] It should be noted that, in order to guide the second camera module 13 to flip relative to the first camera module 12, the second guide segment 1422 of the second guide hole 142 is not limited to extending along a straight line, for example, extending along a second direction. The second guide segment 1422 can also be configured to extend along an arc.

[0083] In some embodiments, such as Figure 2 As shown, in order to facilitate precise control of the second camera module 13 switching to the front camera state, the multi-functional camera module 1 also includes: a first detection element 101 and a control module 103;

[0084] The first detection element 101 is used to detect the position of the first camera module 12 relative to the device body 2. The first detection element 101 is electrically connected to the control module 103, and the control module 103 is electrically connected to the lifting drive component 11.

[0085] When the first detection element 101 detects the position where the first camera module 12 drives the second camera module 13 to the front camera state, the control module 103 controls the lifting drive component 11 to stop operating.

[0086] For example, the first detection element 101 may be configured to include a first Hall sensor 1011 and a first magnet 1012. The first Hall sensor 1011 is fixedly disposed on one side of the first camera module 12, and the first magnet 1012 may be disposed on the first connecting shaft 1201 corresponding to the first camera module 12.

[0087] Meanwhile, the control module 103 can be a circuit board and is communicatively connected to the first Hall sensor 1011, the first camera module 12, and the second camera module 13, respectively.

[0088] When the first camera module 12 is in its initial position, the first magnet 1012 is far away from the first Hall sensor 1011. As the lifting drive 11 drives the first camera module 12 to rise, the second camera module 13 will rise under the drive of the first camera module 12. When the second camera module 13 is in the front-facing state, the first magnet 1012 is close to the first Hall sensor 1011. For example, the first Hall sensor 1011 and the first magnet 1012 are arranged opposite each other along the length of the device body 2. At this time, the first Hall sensor 1011 generates an induction signal, such as a circuit signal, under the trigger of the magnetic field of the first magnet 1012. The control module 103 will control the lifting drive 11 to stop running according to the induction signal generated by the first Hall sensor 1011 to ensure that the second camera module 13 maintains the front-facing state.

[0089] In some embodiments, such as Figure 2 As shown, the multi-functional camera module 1 also includes: a second detection element 102, which is used to detect the position of the second camera module 13 relative to the device body 2, and the second detection element 102 is electrically connected to the control module 103;

[0090] When the second detection element 102 detects the position of the second camera module 13 when it reaches the reading state, the control module 103 controls the lifting drive 11 to stop running.

[0091] For example, the second detection element 102 may be configured to include a second Hall sensor 1021 and a second magnet 1022. The second Hall sensor 1021 is fixedly disposed on one side of the second camera module 13, and the second magnet 1022 may be disposed on the second connecting shaft 1301 corresponding to the second camera module 13.

[0092] To facilitate precise control of the second camera module 13 switching from the front-facing state to the finger-reading state, when the second camera module 13 is in the front-facing state, the second Hall sensor 1021 and the second magnet 1022 can be arranged facing each other horizontally along the length of the device body 2. At this time, the second Hall sensor 1021 can generate a sensing signal triggered by the magnetic field of the second magnet 1022. The control module 103 can determine that the second camera module 13 is in the front-facing state based on the sensing signal generated by the second Hall sensor 1021. When the second Hall sensor 1021 and the second magnet 1022 are facing each other horizontally, the second connecting shaft 1301 can be positioned at the connection point between the first guide section 1421 and the second guide section 1422.

[0093] As the second camera module 13 flips relative to the first camera module 12, when the second connecting shaft 1301 is located at the end of the second guide section 1422 away from the first guide section 1421, it can be considered that the second camera module 13 has switched to the finger reading state. Since the distance between the second Hall sensor 1021 and the second magnet 1022 is greater than the set value, it can be considered that the second Hall sensor 1021 will not generate a sensing signal under the triggering of the magnetic field of the second magnet 1022. At this time, the control module 103 controls the lifting drive component 11 to stop running, which can ensure that the second camera module 13 maintains the finger reading state.

[0094] In practical applications, the second detection element 102 can also be a trigger switch. The trigger switch is located at the end of the second guide section 1422 away from the first guide section 1421. When the second connecting shaft 1301 reaches the end of the second guide section 1422 away from the first guide section 1421, the trigger switch can be triggered to switch states. The control module 103 will control the lifting drive 11 to stop running according to the trigger signal of the trigger switch to ensure that the second camera module 13 maintains the reading state.

[0095] In some embodiments, such as Figure 1 As shown, the lifting drive component 11 includes: a drive motor 111 and a lead screw transmission mechanism 112; the lead screw of the lead screw transmission mechanism 112 is connected to the drive motor 111, and the lead screw nut of the lead screw transmission mechanism 112 is connected to the first camera module 12.

[0096] It is understandable that the drive motor 111 can be a DC servo motor.

[0097] The lead screw transmission mechanism 112 includes a base, a lead screw, a lead screw nut, and a guide rail. The lead screw is rotatably mounted on the base, and the guide rail is mounted on the base. The lead screw and the guide rail are arranged side by side and both extend along the height direction of the equipment body 2. The lead screw nut is sleeved on the lead screw and is threaded into the lead screw. The lead screw nut is also movably mounted on the guide rail along the extension direction of the guide rail.

[0098] In practical applications, the drive motor 111 drives the lead screw to rotate relative to the base. Under the guidance of the guide rail, the lead screw drives the lead screw nut to move along the guide rail, and the lead screw nut drives the first camera module 12 to perform lifting and lowering movements.

[0099] In some embodiments, such as Figure 1 and Figure 4 As shown, the first camera module 12 includes: a first base 121 and a first camera 122;

[0100] The first base 121 is configured to be located on the rear side of the device body 2. The first base 121 is connected to the lifting drive 11 and is rotatably connected to the second camera module 13. The first camera 122 is located on the first base 121 and is positioned facing the rear side of the device body 2.

[0101] It is understood that the first camera 122 can be a wide-angle camera or an autofocus camera. Multiple first cameras 122 can be mounted on the first base 121 to achieve richer shooting effects through the collaboration of multiple first cameras 122. The optical axis of the first camera 122 can be configured to be perpendicular to the back of the device body 2.

[0102] When the first camera module 12 is configured with the first connecting shaft 1201, the first connecting shaft 1201 can be provided on the side of the first base 121, and the first connecting shaft 1201 can be connected to the output end of the lifting drive member 11.

[0103] In some embodiments, such as Figure 6 As shown, the multi-functional camera module 1 also includes a lidar 135, which is located on one side of the second camera module 13 facing the rear of the device body 2. The lidar 135 and the first camera 122 are configured to communicate with the device body 2.

[0104] It is understandable that, such as Figure 8 As shown, the device body 2 typically includes a housing 201 and a display module 202. An opening is formed on the front side of the housing 201, and the display module 202 is installed in the opening. The lidar 135 and the first camera 122 are respectively connected to the control board of the device body 2, and the control board is connected to the display module 202.

[0105] In practical applications, the LiDAR 135 is used to acquire the three-dimensional point cloud of the target object to construct its three-dimensional outline. The first camera 122 is used to acquire the two-dimensional image of the target object, including details such as color and texture. The device body 2 can use the point cloud data acquired by the LiDAR 135 as a framework to map the color and texture information in the two-dimensional image acquired by the first camera 122 onto the corresponding three-dimensional point cloud to generate a three-dimensional model of the target object and control the display module 202 to display it.

[0106] It should be noted that the fusion of data collected by the lidar 135 and the first camera 122 is a conventional technique in this field and does not involve any improvement to the method.

[0107] When the device body 2 is a learning machine, the lidar 135, together with the first camera 122 used for rear-facing cameras, allows students to scan various real-world or geometric objects, generate 3D models, and display them on the learning machine. Students can save, record, review, or modify these models, thereby improving their understanding of complex objects.

[0108] In some embodiments, such as Figure 1 , Figure 5 and Figure 6 As shown, the second camera module 13 includes: a second base 131 and a second camera 132; the second base 131 is rotatably connected to the first camera module 12; the second camera 132 is disposed on the second base 131 and is positioned facing the front of the device body 2.

[0109] The second camera 132 can be a fixed-focus camera or a zoom camera, and multiple second cameras 132 can be set, without specific limitations.

[0110] Meanwhile, the second connecting shaft 1301 shown in the above embodiment is disposed on the side of the second base 131, and the second connecting shaft 1301 is arranged parallel to the rotation axis between the first camera module 12 and the second camera module 13.

[0111] Furthermore, such as Figure 6 As shown, the second camera module 13 also includes a display screen 133, which is configured to communicate with the device body 2. The display screen 133 is located on one side of the second base 131 facing the rear of the device body 2 and is used to display information about the user's operation using the device body 2.

[0112] For example, when the device body 2 is a learning machine, since the display screen 133 is communicatively connected to the device body 2, the information of the student's homework using the device body 2 can be displayed synchronously through the display screen 133. For example, the display screen 133 can display information such as the duration of the student's study and the title of the subject, which makes it convenient for parents to supervise and check the time.

[0113] Furthermore, such as Figure 6 As shown, the second camera module 13 also includes an indicator light 134, which is configured to communicate with the device body 2. The indicator light 134 is located on one side of the second base 131 facing the rear of the device body 2, and is used to provide a light prompt when the user operates the device body 2 for a period of time exceeding a preset value.

[0114] For example, when the device body 2 is a learning machine, when the student uses the device body 2 to learn for a longer period of time than a preset value, the indicator light 134 will turn red to remind parents to remind their children to take a break.

[0115] The indicator light 134 can be an LED light.

[0116] In some embodiments, such as Figure 8 and Figure 9 As shown, this utility model embodiment also provides an electronic device, including: a device body 2 and a multi-functional camera module 1 as described above disposed on the device body 2.

[0117] It is understood that the electronic device shown in this embodiment can be an educational device such as a learning machine or a reading pen. The device body 2 can be placed on a horizontal table by a bracket 3, and the bracket 3 can adjust the tilt angle of the device body 2 relative to the horizontal plane to meet the homework needs of students of different ages.

[0118] like Figure 1 , Figure 8 and Figure 9 As shown, the device body 2 includes a housing 201 and a display module 202. The display module 202 is installed on the front side of the housing 201. A receiving cavity is formed between the housing 201 and the display module 202. The lifting drive 11 and the guide 14 are both located in the receiving cavity. The first camera module 12 is movably disposed on the back of the housing 201. When the first camera module 12 is in the initial state, the first camera module 12 and the second camera module 13 are disposed side by side on the back of the housing 201. During the process of the lifting drive 11 driving the first camera module 12 to rise, the first camera module 12 drives the second camera module 13 to move. Under the guidance of the guide 14, the second camera module 13 first rises to the front camera state and then flips forward to the finger reading state.

[0119] Since the electronic device includes a multi-functional camera module 1, and the specific structure of the electronic device is as described in the above embodiments, the electronic device of this embodiment includes all the technical solutions of the above embodiments. Therefore, all the beneficial effects achieved by all the technical solutions of the above embodiments will not be described in detail here.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
