DETAILED DESCRIPTION

[0061] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0062] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0064] "Smart wearable devices" is a general term for the use of wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes.

[0065] In a broad sense, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0066] As can be seen from the background technology, at present, with the current market demand, in order to pursue a better user experience, smart wearable devices (such as smart bracelets, watches, glasses, jewelry, etc.) generally integrate functions such as shooting, calling, Bluetooth, etc. Taking a smart wearable device with a shooting function as an example, in order to enable the smart wearable device to obtain image information of the user itself and other than the user itself according to the user's choice, one implementation method of the smart wearable device is to use only a front or rear camera, and change the camera shooting direction by flipping the device body 10.

[0067] However, in the related smart wearable device technology that uses a flip device to adjust the camera shooting direction, the flipping of the device body 10 needs to be achieved by manual operation, which not only increases the difficulty of shooting during the flipping process of the camera, but also affects the image stability during the shooting process, reducing the user experience. To this end, this embodiment provides the following solution.

[0068] The present embodiment provides an electronic device, which changes the connection relationship between a device body 10 and a support frame 20 and optimizes the assembly structure therebetween, so that the device body 10 and the support frame 20 can rotate relative to each other within a certain angle range driven by a driving mechanism, thereby solving a series of problems such as the need for manual operation to rotate the device body 10, which makes shooting of the device more difficult, the poor stability of the shooting process, and the limited usage scenarios and conditions.

[0069] This embodiment provides an electronic device, which can be applied to a smart wearable device, such as a smart watch or a smart bracelet, to be used as a host of the smart wearable device.

[0070] Please refer to Figure 1-Figure 8 The electronic device includes a device body 10 and a support frame 20. The device body 10 is used to install functional modules (such as a screen, a camera module, a call module, etc.) in the electronic device. The support frame 20 serves as the supporting body of the electronic device. In the application of smart wearable devices, it can be worn on the human body in conjunction with wearable components and is used to support the device body 10.

[0071] Specifically, the support frame 20 and the device body 10 are connected through a driving mechanism, and the driving mechanism is used to drive the device body 10 to rotate around the Z axis relative to the support frame 20. It can be understood that a battery and a control unit can be provided inside the electronic device. The battery is electrically connected to the control unit as a power source for the driving mechanism to drive the device body 10 to rotate. The control unit is used to respond to the user input operation to send corresponding control instructions to the driving mechanism, so that the driving mechanism drives the device body 10 to rotate around the Z axis relative to the support frame 20, or stops relative movement with the support frame 20.

[0072] It should be understood that the main part of the driving mechanism can be installed on the support frame 20 or the device body 10, wherein the driving mechanism includes a fixed end and an output end that can move relative to each other. In one embodiment, the fixed end is installed and fixed to the support frame 20, and the output end is connected to the device body 10. The driving mechanism drives the device body 10 to move through the output end by realizing the movement of the output end relative to the fixed end. However, in general, the volume of the fixed end of the driving mechanism is larger than that of the output end (such as the housing of the motor used to install the stator is larger than the output shaft of the motor, or the cylinder body of the cylinder is larger than the piston rod of the cylinder). Therefore, the driving mechanism in this embodiment will occupy a larger installation space on the support frame 20, which is not conducive to the support frame 20 and the user's wearing. In another embodiment, the fixed end is installed in the device body 10, and the output end is connected to the support frame 20. Since the fixed end is larger than the output end, the fixed end can also be regarded as the main part of the driving mechanism, that is, the driving mechanism is set in the device body 10, and the device body 10 uses the more abundant installation space inside it relative to the support frame 20 to install and support the fixed end, thereby avoiding the situation of setting a larger fixed end on the support frame 20, so that the volume of the support frame 20 can be reduced accordingly, avoiding the problem of mutual interference between the support frame 20 and the user due to the excessive structure of the support frame 20, affecting the user's use experience. In the above embodiment, since the output end is connected to the support frame 20, and the support frame 20 is in a relatively fixed state with the user's limbs, torso and other body parts in the application of the electronic device as a smart wearable device, therefore, when the driving mechanism is in the driving state, the output end will be in a relatively fixed state with the user, and the fixed end is reversed through the relative movement of the fixed end and the output end, so that the fixed end drives the rotation of the device body 10 relative to the support frame 20, so that the corresponding functional module moves relative to the user around the first rotation axis under the drive of the device body 10.

[0073] On the basis of the above-mentioned embodiment, a universal transmission mechanism 30 is arranged between the output end and the support frame 20. The universal transmission mechanism 30 of this embodiment is configured as a mechanical device for transmitting power and torque. In this embodiment, the universal transmission mechanism 30 limits the relative rotation of the output end and the support frame 20 around the Z-axis, so that the torque rotating around the Z-axis can be transmitted between the support frame 20 and the output end, and the universal transmission mechanism 30 allows relative changes in other directions between the support frame 20 and the output end except for the relative rotation around the Z-axis. For example, the output end moves relative to the support frame 20 in the X-axis and Y-axis directions with the device body 10 relative to the support frame 20, thereby causing relative angle changes in the X-axis and Y-axis directions between the output end and the support frame 20. Since the universal transmission mechanism 30 limits the relative rotation between the output end and the support frame 20 around the Z axis, the universal transmission mechanism 30 can also act as a force between the output end and the support frame 20 in the direction of relative rotation around the Z axis, thereby achieving relative fixation of the output end and the support frame 20 (user) in the direction of rotation around the Z axis and realizing reverse push on the fixed end, allowing the fixed end to drive the device body 10 to rotate relative to the support frame 20, so that the corresponding functional module can move around the first rotation axis relative to the user under the drive of the device body 10.

[0074] Continuing with the above scheme, the universal transmission mechanism 30 allows the connected device body 10 and the support frame 20 to make relative movements in other directions except for relative rotation around the Z axis, and the two can still realize the force transmission function within a certain range of angle changes, so that when the angle of the device body 10 and the support frame 20 changes, or when the two are set at a certain angle, the device body 10 can still rotate around the Z axis relative to the support frame 20 under the action of the driving mechanism, thereby broadening the use scenarios of electronic devices, meeting the use needs of different users for smart wearable devices in different scenarios, and improving the user experience. For example, taking an electronic device provided with a camera module as an example, when the device body 10 needs to rotate relative to the support frame 20 to change the shooting direction of the camera (such as switching between front and rear cameras, or panoramic shooting, etc.), the device body 10 can realize relative rotation with the support frame 20 through a driving mechanism. In this way, the shooting direction of the camera module can change with the rotation of the device body 10. Compared with the user manually operating the rotation of the device body 10, the user's hands do not need to perform related operations during the rotation of the device body 10. The rotation process of the device body 10 is simple and stable, which reduces the difficulty of device shooting and meets the user's shooting needs in different usage occasions and different usage scenarios. It has higher operability and scene adaptability, provides convenience for users to use smart wearable devices, and is more convenient for users to use. At the same time, the device body 10 (output end) can also be set at a certain angle with the support frame 20, such as rotating around the X-axis in the figure to a state inclined relative to the support frame 20, so that the camera module set on the device body 10 can not only be rotated around the Z-axis to change its shooting direction, but also be in a state inclined upward or downward on the horizontal plane while the support frame 20 (such as the user's arms and other body parts) can still be in a horizontal position, avoiding the need to change the shooting direction of the camera module in other directions through the user's limbs. Finally, the device body 10 can also maintain an angle setting with the support frame 20 to complete the shooting of rotating around the Z-axis relative to the support frame 20, which is beneficial for users to shoot under different needs.

[0075] By setting a universal transmission mechanism 30 between the output end and the support frame 20, during the transmission process of the driving mechanism, the universal transmission mechanism 30, in addition to transmitting the torque in the rotation direction around the Z-axis, can also overcome the adverse effects caused by various factors such as eccentricity, angular deviation and distance change between the output end and the support frame 20 during the rotation of the equipment body 10 relative to the support frame 20, thereby ensuring that the transmission can be carried out smoothly and reliably.

[0076] It should be noted that the electronic device can be used as a smart wearable device, such as the main part of a smart watch, in one embodiment, that is, the electronic device can realize functions such as video recording, calling, sending and receiving information, video calling, scanning QR codes, mobile payment, viewing environmental information, and viewing body information. Therefore, in this embodiment, in the application of the electronic device in the smart wearable device, the device body 10 may also include a main board with a control unit, a camera module, a display screen, a battery, a speaker, a microphone, a SIM card seat assembly, a communication module, and sensors for realizing various functions, which are not shown in the figure, wherein the sensor may be a gravity sensor, an acceleration sensor, a distance sensor, a heart rate sensor, an air pressure sensor, an ultraviolet detector, etc. And the device body 10 also includes components for identity recognition, such as a fingerprint recognition module, a facial recognition module, etc.

[0077] When the electronic device of the present application is applied to a smart wearable device, such as a smart watch, in actual use, a wearable component is also provided on the support frame 20, and the support frame 20 can be worn on the user's arm by cooperating with the wearable component, and the wearable component can be a watch strap. When the supported wearable device is a smart glasses, the wearable component can be a glasses frame, and when the smart wearable component is a neck ring, the wearable component can be a flexible belt body used to cooperate with the support frame 20 to be put on the user's neck.

[0078] Exemplarily, according to the above description, the driving mechanism can be configured as a rotating mechanism such as an electric motor that can output torque, or a linear motion mechanism such as a cylinder, an electric push rod, etc., and when the driving mechanism is a rotating mechanism such as an electric motor, the universal transmission mechanism 30 can be configured as a universal joint, and the universal joint can include but is not limited to a cross-axis 33-type (double-type) universal joint, a ball cage universal joint, a three-pin universal joint, etc.

[0079] Please continue to refer to Figure 5-Figure 11, taking the universal transmission mechanism 30 of the present embodiment which adopts a cross-axis universal joint with a relatively simple structure and relatively low cost as an example, the universal transmission mechanism 30 includes a second transmission member 32 and a first transmission member 31, the first end of the second transmission member 32 is fixedly connected to the output end of the driving mechanism, here, if the driving mechanism is configured as a device such as an electric motor for outputting torque, the first rotating member can be set to be coaxially connected to the output end or connected through a transmission mechanism such as a friction wheel group and a dimension group. The first transmission member 31 is installed on the support frame 20, the first end of the first transmission member 31 is fixedly connected to the support frame 20, and the second end of the first transmission member 31 is connected to the second transmission member 32. In this embodiment, the second transmission member 32 defines the rotation axis of the Z axis, and the second transmission member 32 and the first transmission member 31 can move relative to each other around the X axis and the Y axis, wherein the X axis, the Y axis and the Z axis are perpendicular to each other. That is to say, the second transmission member 32 and the first transmission member 31 can realize the torque transmission between the output end and the support frame 20 in the direction of relative rotation around the Z axis, thereby avoiding relative rotation around the Z axis between the output end and the support frame 20. At the same time, the second transmission member 32 and the first transmission member 31 can also be suitable for angle adjustment in the X-axis and Y-axis directions, so that the device body 10 can be set at an angle with the support frame 20 in the X-axis and Y-axis directions, so that the device body 10 can be in a state of leaning forward or backward relative to the support frame 20 and can still rotate around the Z axis.

[0080] Through the above-mentioned arrangement, in addition to allowing the device body 10 and the support frame 20 to rotate around the Z axis within a certain angle range, the relative freedom of movement between the second transmission member 32 and the first transmission member 31 can compensate for the gap error between the device body 10 and the support frame 20, thereby ensuring that the device body 10 can remain stable when rotating around the Z axis relative to the support frame 20.

[0081] Specifically, the second transmission member 32 is provided with a first yoke 311, and the first transmission member 31 is provided with a second yoke 321. The first yoke 311 and the second yoke 321 are movably connected via a cross shaft 33. The cross shaft 33 includes a first shaft body 331 and a second shaft body 332 that are vertically crossed. The axis of the first shaft body 331 and the axis of the second shaft body 332 are on the same horizontal plane to respectively define the above-mentioned X-axis and Y-axis, that is, the first shaft body 331 and the first transmission member 31 are vertically arranged, and the second shaft body 332 and the first transmission member 31 are vertically arranged.

[0082] The first yoke 311 and the second yoke 321 are respectively used as connecting components for movably connecting the second transmission member 32 and the first transmission member 31 to the cross shaft 33. The second transmission member 32 is rotatably connected to the opposite ends of the first shaft 331 through the two opposite fork ears of the first yoke 311, and the first transmission member 31 is rotatably connected to the opposite ends of the second shaft 332 through the two opposite fork ears of the second yoke 321, thereby ensuring that at least two connections are formed between the second transmission member 32 and the first shaft 331, and between the first transmission member 31 and the second shaft 332, respectively, increasing the contact area between the second transmission member 32, the cross shaft 33, and the first transmission member 31, improving the force transmission efficiency of the universal transmission mechanism 30, and ensuring the stability of the relative rotation of the device body 10 around the Z axis when the X-axis and Y-axis directions are set at an angle relative to the support frame 20. At the same time, it also ensures that the second transmission member 32 and the first shaft 331, as well as the first transmission member 31 and the second shaft 332 have a high connection strength.

[0083] It should be understood that the universal transmission mechanism 30 of the present embodiment adopts a cross-axis universal joint. In addition to being suitable for transmitting torque in the Z-axis rotation direction and moving simultaneously in the X-axis and Y-axis directions, the cross-axis universal joint has a relatively simple and compact structure, so the size of the cross-axis universal joint is also relatively small, which is beneficial to the application of electronic devices in smart wearable devices.

[0084] Please refer to Figure 1-Figure 7 A mounting cavity 11 is formed in the hollow of the device body 10. The mounting cavity 11 is used to provide mounting space for various functional modules and components in the electronic device. For example, modules such as the camera module and the display screen in the smart watch are all mounted in the mounting cavity 11 and some modules can be at least partially exposed outside the device body 10. Each functional module and component is mounted in the mounting cavity 11 and can form a matching relationship with the cavity wall of the mounting cavity 11, so that each functional module and component can be constrained at a preset position in the device body 10. Each functional module and component, including the driving mechanism described in this embodiment, is mounted in the device body 10, so that each module component can be located in the mounting cavity 11 to achieve communication connection through connecting wires, thereby avoiding the situation where some module components are installed in the support frame 20 and the connecting wire needs to be led out from the mounting cavity 11 to the support frame 20, and preventing the connection between the connecting wire and the module component from failing due to the relative movement between the device body 10 and the support frame 20.

[0085] In this embodiment, an opening 12 connected to the installation cavity 11 is provided on one side of the device body 10. In this embodiment, the output end is connected to the universal transmission mechanism 30 through a coupling 40, and the coupling 40 is arranged between the output end and the universal transmission mechanism 30. In this way, in the embodiment where the driving mechanism is an electric motor, it is also ensured that the end of the universal transmission mechanism 30 used to connect the output end maintains a coaxial matching relationship with the output end, ensuring a high force transmission efficiency between the support frame 20 and the output end, thereby improving the stability of the device body 10 during rotation. In the above, the opening 12 is used to provide at least part of the output end or at least part of the coupling 40 to extend from the installation cavity 11 to the outside of the device body 10.

[0086] Please refer to Figure 5-Figure 8 Taking the above-mentioned opening 12 as an example, which is used to provide at least a portion of the coupling 40 to extend from the mounting cavity 11 and be connected to the universal transmission mechanism 30, in this embodiment, the driving mechanism is located in the mounting cavity 11, the first end of the coupling 40 is arranged in the mounting cavity 11 and connected to the output end, and the second end of the coupling 40 extends out of the equipment body 10 through the opening 12 and is installed on the support frame 20.

[0087] Here, because the second end of the coupling 40 needs to extend from the opening 12 to the outside of the device body 10 to achieve connection with the universal transmission mechanism 30, and it is necessary to ensure that the device body 10 can smoothly rotate relative to the support frame 20, a certain space gap needs to be reserved between the opening 12 and the part of the coupling 40 extending from the opening 12, but dust, debris, liquids, etc. can easily enter the installation cavity 11 through the space gap between the opening 12 and the coupling 40, thereby affecting the service life of the electronic device. And generally speaking, in the implementation of the electronic device as a smart wearable device, in order to adapt to different use environments, the device body 10 needs to have certain waterproof and dustproof properties to ensure that when it is used as a smart watch, glasses and other devices, it can reduce foreign matter from entering the installation cavity 11 to a certain extent, and play a certain protective function for its internal module components. In order to achieve the above-mentioned purpose, in the present embodiment, the side wall of the opening 12 is sealed with the coupling 40 by a sealing component 41. The sealing component 41 can be configured as a sealing ring or a mechanical sealing structure. The outer side surface of the sealing component 41 is sealed with the side wall of the opening 12, and the inner side surface of the sealing component 41 is sealed with the outer peripheral surface of the coupling 40, thereby preventing foreign objects from the external environment from moving through the space gap between the opening 12 and the coupling 40 and entering the installation cavity 11, thereby effectively extending the service life of the electronic equipment.

[0088] In the above-mentioned embodiment in which the sealing component 41 is a sealing ring, the sealing ring has a certain elastic reset performance, the coupling 40 is connected to the sealing ring, and the outer circumference and the inner circumference of the sealing ring are respectively abutted against the side wall of the opening 12 and the coupling 40 and are compressed to a certain extent. In addition to the waterproof and dustproof sealing function, it can also provide a stable friction force between the coupling 40 and the device body 10, so that the device body 10 can play a damping role when it rotates relative to the support frame 20. In the process of relative movement between the coupling 40 and the device body 10, the relative offset between the two can also be compensated, thereby reducing the relative shaking between the device body 10 and the support frame 20 and improving the stability of the device body 10 during rotation.

[0089] In another embodiment, taking the above-mentioned opening 12 as an example of a solution in which at least part of the output end is used to extend from the mounting cavity 11 and is connected to the universal transmission mechanism 30 through the coupling 40, in the driving mechanism, the fixed end and at least part of the output end are located in the mounting cavity 11, and the output end at least partially extends out of the device body 10 through the opening 12 and is connected to the first end of the coupling 40, and the second end of the coupling 40 is connected to the support frame 20 through the universal transmission mechanism 30.

[0090] Similar to the above-mentioned embodiment, since the output end needs to at least partially extend from the opening 12 to the outside of the device body 10 and is connected to the universal transmission mechanism 30 through the coupling 40, and it is necessary to ensure that the device body 10 can smoothly rotate relative to the support frame 20, a certain space gap needs to be reserved between the opening 12 and the portion of the output end extending from the opening 12, but dust, debris, liquids, etc. can easily enter the installation cavity 11 through the space gap between the opening 12 and the output end, thereby affecting the service life of the electronic device. And generally speaking, in the embodiment of the electronic device as a smart wearable device, in order to adapt to different use environments, the device body 10 needs to have certain waterproof and dustproof properties to ensure that when it is used as a smart watch, glasses and other devices, it can reduce the entry of foreign matter into the installation cavity 11 to a certain extent, and play a certain protective function for its internal module components. In order to achieve the above-mentioned purpose, in the present embodiment, the side wall of the opening 12 is sealed with the output end by a sealing component 41, and the sealing component 41 can be configured as a sealing ring or a mechanical sealing structure. The outer side surface of the sealing component 41 is sealed with the side wall of the opening 12, and the inner side surface of the sealing component 41 is sealed with the output end, thereby preventing foreign objects from the external environment from moving through the space gap between the opening 12 and the output end and entering the installation cavity 11, thereby effectively extending the service life of the electronic device.

[0091] In the above-mentioned embodiment where the sealing component 41 is a sealing ring, the sealing ring has a certain elastic reset performance, the output end is connected to the sealing ring, and the outer circumference and the inner circumference of the sealing ring are respectively abutted against the side wall of the opening 12 and the output end, which can not only play a waterproof and dustproof sealing function, but also increase the friction between the output end and the device body 10, so that the device body 10 plays a damping role when rotating relative to the support frame 20, and can also compensate for the relative offset between the output end and the device body 10 during the relative movement of the two, thereby improving the stability of the device body 10 during rotation.

[0092] It should be understood that in the above-mentioned embodiment of setting the sealing component 41, the sealing component 41 can be set to at least one. For example, when the driving mechanism is completely set in the installation cavity 11, the coupling 40 passes through the device body 10 through the opening 12 and a sealing component 41 is set between the coupling 40 and the side wall of the opening 12. Here, two sealing rings are set between the coupling 40 and the opening 12, and the two sealing rings can be set to abut against each other, or as shown in FIG. Figure 5-Figure 7 As shown, two sealing grooves 42 spaced apart along the Z axis are formed on the coupling 40, so that two sealing rings are at least partially embedded in the sealing grooves 42, respectively, thereby improving the sealing performance between the coupling 40 and the device body 10. Similarly, in the embodiment where the output end at least partially extends out of the device body 10 through the opening 12, and two or more sealing rings are provided, two adjacent sealing rings can also be fixed by the above-mentioned side-by-side contact or spaced arrangement.

[0093] Of course, in other embodiments, if the driving mechanism and the universal transmission mechanism 30 are connected by a connection structure or method other than the coupling 40, in the embodiment in which the universal transmission mechanism 30 includes a second transmission member 32 and a first transmission member 31, the second transmission member 32 of the universal transmission mechanism 30 can also enter the installation cavity 11 through the opening 12 and connect to the output end, and the sealing component 41 is arranged between the second transmission member 32 and the side wall of the opening 12 to implement sealing.

[0094] In this embodiment, since the output end is coaxially connected to the second transmission member 32 of the universal transmission mechanism 30 through the coupling 40, that is, the output end, the coupling 40, and the second transmission member 32 are all on the same axis. Therefore, when the output end moves with the device body 10 relative to the support frame 20 in the X-axis and Y-axis directions, the coupling 40 and the second transmission member 32 also move relative to the support frame 20 in the X-axis and Y-axis directions. Therefore, the relative positions of the output end, the coupling 40, the second transmission member 32 and the device body 10 in the X-axis and Y-axis directions also remain unchanged, thereby ensuring that the sealing component 41 can provide stable sealing performance.

[0095] Please continue to refer to Figure 1-Figure 6 On the basis of the above-mentioned embodiment, the device body 10 includes a first housing 13 and a second housing 14. The second housing 14 and the first housing 13 are detachably connected and enclosed to form an installation cavity 11. When the internal module components of the electronic device are disassembled and assembled, the first housing 13 and the second housing 14 of the device body 10 can be disassembled and separated, so that the installation cavity 11 is opened to the external environment as a whole, so as to facilitate the disassembly, assembly, inspection and other operations of the module components in the installation cavity 11.

[0096] Furthermore, the opening 12 is formed in the first housing 13 or the second housing 14, and the opening 12 is directly processed on the first housing 13 or the second housing 14, so that the processing accuracy of the opening 12 can be well controlled, ensuring that the side wall of the opening 12 and the sealing component 41 have good sealing performance in the assembled state, and further allowing the assembly relationship between the sealing component 41 and the coupling 40, or the output end, or the second transmission member 32 to meet the sealing performance requirements of the electronic equipment. It is avoided that the opening 12 is formed by the first housing 13 and the second housing 14, and the opening 12 is deformed due to assembly strength, processing error, deformation, etc. between the first housing 13 and the second housing 14, thereby affecting the sealing performance between it and the sealing component 41.

[0097] As an optional implementation of the present solution, the driving mechanism may be connected via a reduction transmission mechanism, thereby improving the rotation stability of the device body 10 during operation of the driving mechanism.

[0098] Please refer to Figure 5-Figure 8 In one embodiment, a transmission shaft 50 is provided between the driving mechanism and the universal transmission mechanism 30, the first end of the transmission shaft 50 is transmission-connected with the output end, and the second end of the transmission shaft 50 is connected with the universal transmission mechanism 30. In the scheme in which the transmission shaft 50 is provided between the driving mechanism and the universal transmission mechanism 30, the transmission shaft 50 can be connected with the universal transmission mechanism 30 (the second transmission member 32) through the coupling 40 in the above embodiment, or directly connected with the universal transmission mechanism 30. Since the transmission shaft 50 is transmission-connected with the output end of the driving mechanism and is used to output the power of the driving mechanism, the transmission shaft 50 of this embodiment can also be regarded as the output end of the driving mechanism together with the output end of the driving mechanism, and in the embodiment in which the driving mechanism is an electric motor, the first end of the transmission shaft 50 can be provided with a transmission wheel (such as a friction wheel, a gear, etc.) that is transmission-matched with the output shaft of the electric motor, or the transmission shaft 50 can be driven by high-frequency vibration, toggling, etc.

[0099] In order to allow the transmission shaft 50 to be stably placed in the installation cavity 11 and play a role in transmitting the torque between the output end and the universal transmission mechanism 30, a rotating shaft bracket 60 is also provided in the device body 10, and the rotating shaft bracket 60 is fixedly connected to the device body 10. In this embodiment, the first support arm 65 and the second support arm 66 are respectively extended outward on the opposite sides of the rotating shaft bracket 60 (or any two sides). When the rotating shaft bracket 60 is located in the installation cavity 11, it can be supported and fixedly installed on the device body 10 by the first support arm 65 and the second support arm 66. In addition, an axial hole 61 is opened on the rotating shaft bracket 60. The first end of the transmission shaft 50 is located at the upper part of the rotating shaft bracket 60, and the second end of the transmission shaft 50 extends to the lower part of the rotating shaft bracket 60 through the axial hole 61 and forms a clearance fit with the axial hole 61, so that when the transmission shaft 50 is driven by the driving mechanism, its second end can rotate synchronously with the first end under the constraint of the axial hole 61. Since the shaft bracket 60 is fixed to the device body 10, that is, the shaft bracket 60 is also relatively fixed to the fixed end of the driving mechanism, and even in some embodiments, the shaft bracket 60 plays the effect of fixing the fixed end of the driving mechanism, therefore, in this embodiment, the shaft bracket 60 can also be regarded as a fixed end.

[0100] In order to feedback the rotation data of the device body 10 while ensuring a compact structure and saving installation space, this embodiment adopts an embodiment of capturing the rotation data of the transmission shaft 50. Specifically, the first end of the transmission shaft 50 is provided with a magnet 53 that rotates synchronously therewith. The magnet 53 can be configured as a cylinder and its center line coincides with the first rotation axis, making full use of the axial assembly space between the components. A sensor element 15 such as a Hall sensor is also provided on the side of the cavity wall of the installation cavity 11 opposite to the magnet 53, so as to obtain the rotation data of the magnet 53, accurately obtain the current relative position between the device body 10 and the support frame 20, and improve the activity accuracy of the electronic device.

[0101] Please continue to refer to Figure 5-Figure 8Based on the embodiment provided above, a support plate 51 is convexly provided on the outer periphery of the transmission shaft 50 near its first end. It can be understood that the shaft bracket 60 cooperates with the clearance of the transmission shaft 50 body through the shaft hole 61 to constrain and limit the radial range of movement of the transmission shaft 50 and provide the transmission shaft 50 with a degree of freedom of rotation in the circumferential direction. The support plate 51 and the shaft bracket 60 are movably cooperated, and the transmission shaft 50 is supported on the shaft bracket 60 through the support plate 51. In this way, the transmission shaft 50 can be hung on the shaft bracket 60 through the support plate 51 in the direction of gravity, so that the transmission shaft 50 is supported on the shaft bracket 60 through the support plate 51, constraining the freedom of movement of the transmission shaft 50 from its first end to the second end, ensuring that the first end of the transmission shaft 50 maintains a good transmission relationship with the driving mechanism, and as the output end of the driving mechanism, it also ensures that the second end of the transmission shaft 50 can maintain a good transmission relationship with the universal transmission mechanism 30 through the coupling 40.

[0102] In the above-mentioned embodiment, the support plate 51 between the transmission shaft 50 and the rotating shaft bracket 60 constrains the freedom of movement of the transmission shaft 50 from the first end to the second end. In one embodiment, a magnetic component is arranged between the support plate 51 and the rotating shaft bracket 60, and the magnetic component is used to continuously apply a magnetic attraction force to the support plate 51 along the axial direction of the transmission shaft 50 close to the rotating shaft bracket 60. In this way, the support plate 51 can be stably magnetically attracted to the rotating shaft bracket 60 through the magnetic attraction component. The magnetic attraction component constrains the freedom of movement of the transmission shaft 50 in the axial direction, so that the rotating shaft bracket 60 can stably provide a limiting function for the support plate 51, and the transmission shaft 50 will not easily detach from the shaft hole 61, thereby ensuring that the transmission shaft 50 has good force transmission efficiency.

[0103] In other embodiments, in order to allow the support plate 51 to be stably restricted on the rotating shaft bracket 60, springs, silicone columns, rubber columns, plastic columns or foam columns with elastic reset functions and limiting components (such as limiting buckles, etc.) can be arranged between the support plate 51 and the rotating shaft bracket 60, or between the transmission shaft 50 and the rotating shaft bracket 60, so as to constrain the transmission shaft 50 and the rotating shaft bracket 60 and achieve the above-mentioned technical purpose.

[0104] In one embodiment, in an implementation scheme in which a support plate 51 is provided, a limiting convex edge (not shown) is provided on the outer edge of the support plate 51 from the first end of the transmission shaft 50 toward the second end thereof and is arranged around the periphery of the transmission shaft 50. Correspondingly, a first limiting groove (not shown) is provided around the shaft hole 61 and aligned with the limiting convex edge on the side of the rotating shaft bracket 60 close to the support plate 51. While the rotating shaft bracket 60 provides support to the transmission shaft 50 through the support plate 51, the limiting convex edge is clearance-matched with the first limiting groove, thereby further restricting the radial freedom of movement of the transmission shaft 50, so that the transmission shaft 50 can stably provide the force transmission function.

[0105] Of course, by utilizing the limiting principle of the above embodiment, a first limiting groove may be concavely provided on the outer edge of the support plate 51 , and correspondingly, a limiting convex edge may be convexly provided on the rotating shaft bracket 60 .

[0106] Please continue to refer to Figure 5-Figure 8 , continuing to take the implementation method in which a magnetic component is arranged between the support plate 51 and the rotating shaft bracket 60 as an example, specifically, the magnetic component includes a first magnetic component 62 and a second magnetic component 52, and the first magnetic component 62 and the second magnetic component 52 are configured to generate magnetic attraction force to each other, and the first magnetic component 62 is arranged on the rotating shaft bracket 60 around the outer periphery of the shaft hole 61, and correspondingly, the second magnetic component 52 is arranged on the support plate 51 around the outer periphery of the transmission shaft 50 and is aligned with the first magnetic component 62. The first magnetic component 62 and the second magnetic component 52 are in a state of being respectively assembled on the rotating shaft bracket 60 and the support plate 51. Positions are close to each other, thereby generating magnetic attraction force to each other, so that the support plate 51 has a force to abut against the rotating shaft bracket 60 under the interaction of the first magnetic component 62 and the second magnetic component 52, so as to keep the support plate 51 and the transmission shaft 50 in a state of being assembled in place on the rotating shaft bracket 60.

[0107] It can be understood that the first magnetic component 62 and the second magnetic component 52 can both be set as magnets, and, in this embodiment, the side of the first magnetic component 62 facing the second magnetic component 52 and the side of the second magnetic component 52 facing the first magnetic component 62 are respectively configured as opposite magnetic poles to ensure that magnetic attraction rather than magnetic repulsion can be generated between the first magnetic component 62 and the second magnetic component 52.

[0108] In other embodiments, one of the first magnetic component 62 and the second magnetic component 52 may be configured as a magnet, and the other may be configured as a ferromagnetic metal.

[0109] Continuing with the above-mentioned embodiment, one of the first magnetic member 62 or the second magnetic member 52 can be multiple, and the other can be set as a circular ring structure. Specifically, when there are multiple first magnetic members 62, multiple first magnetic members 62 are arranged on the rotating shaft bracket 60 at intervals around the outer periphery of the shaft hole 61, and correspondingly, the second magnetic member 52 with a circular ring structure is arranged on the support plate 51 and arranged around the transmission shaft 50; when there are multiple second magnetic members 52, multiple second magnetic members 52 are arranged on the support plate 51 at intervals around the transmission shaft 50, and correspondingly, the first magnetic member 62 with a circular ring structure surrounds the shaft hole 61 and is arranged on the rotating shaft bracket 60.

[0110] The above-mentioned embodiment provides a structure of a support plate 51 and a magnetic component to constrain the axial and, to a certain extent, radial freedom of the transmission shaft 50. However, under the action of the above-mentioned magnetic component, the support plate 51 will be adsorbed on the rotating shaft bracket 60 through the magnetic component, resulting in an increase in the friction between the support plate 51 and the rotating shaft bracket 60, affecting the relative rotation of the transmission shaft 50 and the rotating shaft bracket 60. In order to ensure that the above-mentioned structure can stably provide the axial limiting function of the transmission shaft 50, and to reduce the friction between the support plate 51 and the rotating shaft bracket 60 to a certain extent, so that the transmission shaft 50 can be located in the shaft hole 61 and rotate smoothly, please refer to Figure 5-Figure 6 , Figure 8 A first rolling component 63 is provided between the support plate 51 and the rotating shaft bracket 60, and the support plate 51 slides with the rotating shaft bracket 60 through the first rolling component 63. It can be understood that the implementation method with the first rolling component 63 can be independent of the implementation method with the magnetic component, that is, only the first rolling component 63 or only the magnetic component is provided between the support plate 51 and the rotating shaft bracket 60. In the implementation method in which only the first rolling component 63 is provided between the support plate 51 and the rotating shaft bracket 60, the transmission shaft 50 is hung on the rotating shaft bracket 60 through the support plate 51 along the direction of gravity, and the first rolling component 63 serves as a supporting component between the rotating shaft bracket 60 and the support plate 51, so that a gap is formed between the support plate 51 and the side surface of the rotating shaft bracket 60 for setting the first rolling component 63, thereby reducing the contact surface and friction coefficient between the two, so that the transmission shaft 50 can rotate relative to the rotating shaft bracket 60 more smoothly.

[0111] In the above embodiment, the first rolling component 63 can be configured as a rolling component such as a ball or roller that reduces the contact surface and friction coefficient between the support plate 51 and the shaft bracket 60. In addition, in order to avoid the problem of increasing the internal space occupied by the installation cavity 11 due to the addition of the first rolling component 63, in the present embodiment, the shaft bracket 60 is provided with a plurality of second limiting grooves 64 spaced around the shaft hole 61. The depth of the second limiting groove 64 needs to be set to be smaller than the first rolling component 63, and the size enclosed by the side wall of the second limiting groove needs to be set to be larger than the first rolling component 63, so that the first rolling component 63 can be movably arranged in the second limiting groove and at least partially protrude from the surface of the shaft bracket 60 at the notch of the second limiting groove to cooperate with the support plate 51. In an embodiment in which a magnetic component is provided, the support plate 51, under the action of the first magnetic component 62 and the second magnetic component 52, presses against the portion of the first rolling component 63 protruding from the rotating shaft bracket 60. At this time, a gap is formed between the first magnetic component 62 and the second magnetic component 52. On the basis of ensuring that a magnetic attraction force can be generated between the two, the situation in which the two are attracted to each other and the friction between the transmission shaft 50 and the rotating shaft bracket 60 is increased is avoided.

[0112] It is worth mentioning that in order to ensure that the above-mentioned structure does not occupy too much installation space in the installation cavity 11, the support plate 51 and the rotating shaft bracket 60 are respectively used to set the second magnetic component 52 and the first magnetic component 62, and are provided with installation grooves for accommodating at least part of the second magnetic component 52 and the first magnetic component 62.

[0113] In this embodiment, a piezoelectric motor is used as a driving mechanism. It can be understood that the piezoelectric motor has a relatively small overall volume, which is conducive to the application in small supporting wearable devices such as smart watches and bracelets. The piezoelectric motor can adopt any structural form provided in the prior art to achieve the technical purpose of this embodiment. Therefore, the specific structure of the piezoelectric motor is not shown in the drawings of this embodiment. Only a mounting position 67 for supporting the piezoelectric motor is provided on one side of the rotating shaft bracket 60. Therefore, in this embodiment, in order to facilitate the understanding of the scheme, the transmission shaft 50 is regarded as the output end of the driving mechanism, and the rotating shaft bracket 60 is regarded as the fixed end of the driving mechanism.

[0114] Please refer to Figure 5-Figure 8 The electronic device of this embodiment also includes a first rotating shaft base 70, which is arranged between the support frame 20 and the device body 10, specifically between the support frame 20 and the universal transmission mechanism 30. As one of the supporting members of the device body 10 located on the support frame 20, the first rotating shaft base 70 and the device body 10 are restricted in the freedom of relative rotation around the Z axis, that is, when the device body 10 rotates relative to the support frame 20 around the Z axis, the device body 10 will drive the first rotating shaft base 70 to move relative to the support frame 20 around the Z axis. To achieve this purpose, the first rotating shaft base 70 needs to be set to a structural form connected to the support frame 20 for rotation around the Z axis, so that the first rotating shaft base 70 can rotate relative to the support frame 20 together with the device body 10.

[0115] Further, in order to increase the adjustable range of the device body 10, the device body 10 is rotatably connected to the first rotating shaft base 70 around the X-axis rotation axis. Here, the Z-axis is perpendicular to the X-axis. In this embodiment, taking the support frame 20 placed horizontally as an example, the X-axis is parallel to the horizontal plane, and the Z-axis is perpendicular to the horizontal plane. In this way, when the lower part of the device body 10 is installed on the support frame 20 through the first rotating shaft base 70, the device body 10 can be swung in a direction close to or away from the support frame 20 by rotating around the X-axis, so that the device body 10 can be stacked on the support frame 20 (such as Figure 3-Figure 4 , Figure 6 ), or erected on the support frame 20 along the Z-axis direction (as shown Figure 1-Figure 2 , Figure 5As shown), and in any position stacked on the support frame 20 or standing upright between the support frames 20, and when the device body 10 is in any of the above states, the device body 10 can be rotated around the Z-axis relative to the support frame 20 under the action of the driving mechanism, thereby achieving the purpose of changing the orientation of the device body 10 and the functional modules (such as the camera module) arranged on the device body 10.

[0116] It is understandable that the process of the device body 10 rotating around the X-axis relative to the support frame 20 can also be automatically adjusted with the assistance of a driving device such as a motor. In this embodiment, in order to avoid the relevant module components occupying too much installation space on the support frame 20 or the first rotating shaft base 70, the rotation of the device body 10 around the X-axis of this embodiment is configured to rely on human power. In order to achieve self-locking of the device body 10 on the X-axis, a damping member such as a bushing can be provided between the device body 10 and the first rotating shaft base 70 to provide a certain force between the two, so that the device body 10 can be maintained in the current position state in the direction around the X-axis even without the action of external force, and is relatively fixed with the support frame 20.

[0117] In the above-mentioned embodiment, the device body 10 is rotatably mounted on the support frame 20 via the first rotating shaft base 70, and the support frame 20 is relatively fixed with the output end in the direction of relative rotation around the Z axis via the universal transmission mechanism 30, so that the device body 10 can be relatively rotated with the support frame 20 around the X axis. Since the universal transmission mechanism 30 can provide the degree of freedom of movement in directions other than the degree of freedom of rotation around the Z axis, no matter the device body 10 is erected on the support frame 20 in the X-axis direction (the device body 10 and the support frame 20 are at a position of 90° or approaching 90°, and / or the second transmission member 32 and the first transmission member 31 are relatively fixed in the direction of relative rotation around the Z axis, the device body 10 can be relatively rotated with the support frame 20 around the X axis. Since the universal transmission mechanism 30 can provide the degree of freedom of movement in directions other than the degree of freedom of rotation around the Z axis, the device body 10 can be relatively rotated with the output end in the direction of relative rotation around the Z axis. At 180° or approaching 180°), or the device body 10 is stacked on the support frame 20 in the X-axis direction (the device body 10 and the support frame 20 are at 0° or approaching 0 degrees, and / or the second transmission member 32 and the first transmission member 31 are at 90° or approaching 90°), and any position between the above two states, the universal drive mechanism can provide the device body 10 with the freedom of movement to rotate around the Z-axis relative to the support frame 20 under the drive of the drive mechanism, and ensure the torque transmission between the support frame 20 and the output end in the direction around the Z-axis, so as to meet the different usage requirements of different users for the electronic device.

[0118] Continuing with the above embodiment, for example, when the electronic device is in a position where it is erected on the support frame 20 and stacked between the support frames 20, at this time, the relative angle between the second transmission member 32 and the first transmission member 31 on the X-axis is between 90°-180°, and the Y-axis is maintained at 180°. When the driving mechanism starts to drive the device body 10 to rotate relative to the support frame 20 around the Z-axis, the second transmission member 32 and the first transmission member 31 will achieve relative movement on the Y-axis along with the movement of the device body 10. The reason is that the universal transmission mechanism 30 cannot achieve rotation relative to the support frame 20 on the Z-axis. At this time, for example, the device body 10 is rotated from Figure 1-Figure 2 , Figure 5 When the state is rotated 45° around the Z axis, the relative angle between the second transmission member 32 and the first transmission member 31 on the Y axis is between 90° and 180°, and remains at 180° on the X axis.

[0119] In order to improve the matching stability between the device body 10 and the first rotating shaft base 70, and to avoid the problem of an increase in the overall volume of the product due to the addition of the first rotating shaft base 70 to the greatest extent, a avoidance groove 16 is provided at the lower part of the device body 10 of this embodiment, and the notch of the avoidance groove 16 is formed on the lower side of the device body 10, and the first rotating shaft base 70 is at least partially located in the avoidance groove 16, and the groove walls on both sides of the avoidance groove 16 are respectively aligned with the opposite side walls of the first rotating shaft base 70 and are respectively connected through rotating shafts.

[0120] In the above scheme, the opening 12 of the device body 10 is opened on the bottom of the avoidance groove 16 away from its groove mouth, and the output end of the driving mechanism (which can also be the transmission shaft 50) or the coupling 40 extends through the opening 12 to the avoidance groove 16 and is connected to the support frame 20 through the universal transmission mechanism 30. In order to avoid the influence of the universal transmission mechanism 30 on the movement of the device body 10 on the X-axis, the rotation axis position of the second transmission member 32 and the first transmission member 31, and the rotation axis position between the device body 10 and the first rotation axis bracket 60 are on the same plane and are coaxially arranged.

[0121] Based on the above embodiment in which the first rotating shaft base 70 is provided, in order to facilitate the assembly between the first rotating shaft base 70 and the support frame 20, and to facilitate the cooperation between the universal transmission mechanism 30 and the support frame 20, please refer to Figure 5-Figure 8The electronic device also includes a second rotating shaft base 80. In this embodiment, the second rotating shaft base 80 is detachably connected to the support frame 20. Specifically, the second rotating shaft base 80 is fixedly connected to at least part of the universal transmission mechanism 30, that is, the second rotating shaft base 80 and the universal transmission mechanism 30 (first transmission member 31) are relatively fixed in the direction of relative rotation around the Z axis, and the first end of the universal transmission mechanism 30 connected to the output end and the second end connected to the second rotating shaft base 80 can move relative to each other around the X axis and the Y axis, while ensuring that the device body 10 can move around the X axis between the position upright on the support frame 20 and the position stacked on the support frame 20, the device body 10 is provided with the freedom of movement in the X axis and the Y axis directions.

[0122] Through the above-mentioned embodiment, one end of the universal transmission mechanism 30 (the first transmission member 31) can first cooperate with the second rotating shaft base 80, and then the device body 10 can be assembled on the support frame 20 through the second rotating shaft base 80, so as to avoid the problem that after the device body 10 is close to the support frame 20, the operating space between the two is narrow, which makes it difficult to assemble the universal transmission mechanism 30 and the support frame 20.

[0123] Please refer to Figure 5-Figure 8 In order to further facilitate the assembly and disassembly between the device body 10 and the support frame 20, the device body 10 and the support frame 20 are actually supported and connected by the second rotating shaft base 80 in this embodiment. The first rotating shaft base 70 and the second rotating shaft base 80 (support frame 20) can rotate relative to each other around the Z axis, and the universal transmission mechanism 30 is also fixed on the second rotating shaft base 80, and its second transmission member 32 defines the Z axis. The second transmission member 32 can move relative to the first transmission member 31 on the X axis and the Y axis along with the device body 10. Here, the second rotating shaft base 80 and the support frame 20 can be connected by a removable connection method of snap fit through an elastic buckle 21 and a buckle groove 81 to achieve the purpose of quick disassembly and assembly. For example, a buckle groove 22 adapted to the second supporting base structure is concavely provided on the support frame 20, and an elastic buckle 21 or a buckle groove 81 is provided in the buckle groove 22, and a buckle groove 81 or an elastic buckle 21 that matches the elastic buckle 21 or the buckle groove 81 is correspondingly provided on the side wall of the second rotating shaft base 80, so that the second rotating shaft base When 80 is placed in the buckle groove 22, the elastic buckle 21 and the buckle groove 81 are engaged with each other, so that the second shaft base 80 can be stably placed on the support frame 20. When the second shaft base 80 needs to be removed from the support frame 20, a force in a relatively away direction is applied to the second shaft base 80 and the support frame 20 respectively, so that the elastic buckle 21 is pushed and elastically compressed, and finally disengaged from the buckle groove 81, so that the second shaft base 80 can be separated from the support frame 20.

[0124] Exemplarily, the elastic buckle 21 can be provided with elastic reset capability by a spring disposed on the support frame 20 or the second rotating shaft base 80 , so that it can remain buckled in the buckle groove 81 in the absence of other external forces.

[0125] In one embodiment, the first rotating shaft base 70 and the second rotating shaft base 80 can be arranged at intervals and respectively mounted and matched with the supporting frame 20 .

[0126] In this embodiment, please continue to refer to Figure 5-Figure 8 In order to further reduce the difficulty of disassembling and assembling the electronic device, the first rotating shaft base 70 is arranged on the upper part of the second rotating shaft base 80, and the first rotating shaft base 70 can rotate relative to the second rotating shaft base 80 around the Z axis. Specifically, the first rotating shaft base 70 is at least partially covered on the second rotating shaft base 80, and in order to avoid the interference between the cooperation between the first rotating shaft base 70 and the second rotating shaft base 80 on the force transmission between the second rotating shaft base 80 and the universal transmission mechanism 30, the first rotating shaft base 70 is provided with a avoiding hole 71, and correspondingly, the first end (the second transmission member 32) of the universal transmission mechanism 30 is fixedly connected to the second rotating shaft base 80, and the second end (the first transmission member 31) of the universal transmission mechanism 30 can be movably connected to the second rotating shaft base 80 and the output end through the avoiding hole 71.

[0127] In this way, the first shaft base 70 can be pre-installed on the second shaft base 80, and the first shaft base 70 and the equipment body 10 can be installed on the support frame 20 together through the second shaft base 80, saving the assembly steps of separately installing the first shaft base 70 and the second shaft base 80 on the support frame 20.

[0128] In one embodiment, since the first rotating shaft base 70 is installed on the upper part of the second rotating shaft base 80, that is, the first rotating shaft base 70 is supported on the support frame 20 through the second rotating shaft base 80, mutual friction will be generated between the first rotating shaft base 70 and the second rotating shaft base 80 during the relative rotation, resulting in an excessively large friction coefficient between the two, thereby affecting the rotation of the device body 10 around the Z axis. To solve this problem, a lubrication component such as a second rolling component (not shown) can be provided between the first shaft base 70 and the second shaft base 80. The provision of the second rolling component can reduce the contact surface and friction coefficient between the first shaft base 70 and the second shaft base 80. Its principle and structure are the same as those of the first rolling component 63. The first shaft base 70 slides with the second shaft base 80 through the second rolling component. In this embodiment, the first shaft base 70 is supported on the second shaft base 80 through the second rolling component. At this time, a gap is formed between the first shaft base 70 and the second shaft base 80 to avoid contact between the two and increase friction, thereby affecting the rotation of the equipment body 10 around the first rotation axis.

[0129] Similarly, in the above embodiment, in order to avoid the existence of the second rolling component causing the gap between the first rotating shaft base 70 and the second rotating shaft base 80 to be too large, thereby increasing the overall volume of the electronic device, in this embodiment, a plurality of third limiting grooves (not shown) are opened on the second rotating shaft base 80 and spaced around the avoiding hole 71. The depth of the third limiting groove needs to be set to be smaller than the second rolling component, and the size enclosed by the side wall of the third limiting groove needs to be set to be larger than the second rolling component, so that the second rolling component can be movably arranged in the third limiting groove and at least partially protrude from the surface of the second rotating shaft base 80 at the notch of the third limiting groove, and cooperate with the first rotating shaft base 70.

[0130] Please continue to refer to Figure 5-Figure 8 A avoidance hole 71 is provided on the first rotating shaft base 70. In an embodiment in which the universal transmission mechanism 30 includes a second transmission member 32, a first transmission member 31 and a cross shaft 33, a second transmission member 32 is fixedly provided on the second rotating shaft base 80 and passes through the avoidance hole 71 to the upper part of the first rotating shaft base 70. The second transmission member 32 is connected to the first transmission member 31 through the cross shaft 33.

[0131] like Figure 1-Figure 4 As shown, this embodiment also provides a smart wearable device, which includes the electronic device as described above. In the embodiment of the smart wearable device, a wearable component (not shown) is provided on the support frame 20, and the support frame 20 can be worn on the human body through the wearable component.

[0132] A camera module is provided on the device body 10. Taking the smart wearable device as a smart watch as an example, the support frame 20 is worn on the user's wrist through a strap as a wearable component. The device body 10 as a watch body can be swung relative to the support frame 20 around the X-axis to move between a position stacked on the support frame 20 and a position upright on the support frame 20. When the device body 10 needs to rotate relative to the support frame 20 around the Z-axis to change the shooting direction of the camera (such as switching between front and rear cameras, or panoramic shooting, etc.), the device body 10 can achieve relative rotation with the support frame 20 through a driving mechanism, and the universal transmission mechanism 30 can provide freedom of movement in the X-axis and Y-axis directions. In this way, the shooting direction of the camera module can change with the rotation of the device body 10 to meet the needs of different users in different usage scenarios.
