[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 can rotate relative to the support frame 20 under the drive of a driving mechanism, thereby solving a series of problems such as the need for manual operation to rotate the device body 10, which makes it difficult to shoot the device, and poor stability during the shooting process.

[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 driven and cooperated through a driving mechanism, and the driving mechanism is used to drive the device body 10 to rotate around the first rotation 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 driving the device body 10 to rotate. The control unit is used to respond to the user's 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 first rotation 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. The driving mechanism includes a fixed end and an output end that can move relatively. In one embodiment, the fixed end is 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 by realizing the movement of the output end relative to the fixed end. However, in general, the fixed end of the driving mechanism is larger in volume than the output end (such as the housing for installing the stator of the motor 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 seat to install and support the fixed end, thereby avoiding the situation of setting a larger fixed end on the support seat, so that the volume of the support seat can be reduced accordingly, avoiding the problem of mutual interference with the user caused by the support seat structure being too large, affecting the user's 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 a 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 device body 10 to rotate 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] In this embodiment, a reduction transmission mechanism 40 is provided between the output end and the support frame 20. It should be understood that the transmission reduction mechanism in this embodiment is a power transmission mechanism, which can use a speed converter of a transmission wheel (such as a friction wheel, a gear) to reduce the speed of the driving mechanism (such as the rotation speed of the motor, the extension and retraction speed of the cylinder piston rod) to a desired speed and obtain a device with a large torque. Among them, the reduction transmission mechanism 40 includes a first end and a second end that can move relative to each other. The first end and the second end of the reduction transmission mechanism 40 are respectively used to connect two relatively movable moving parts, so as to change the speed between the two moving parts through a preset reduction ratio. In this embodiment, the reduction transmission mechanism 40 is used to transmit the driving force between the device body 10 and the support frame 20 around the first rotation axis, so that the speed of the device body 10 rotating relative to the support frame 20 around the first rotation axis is lower and more stable than the speed between the fixed end and the output end. Similarly, in order to save the installation space occupied by related functional components on the support frame 20 and enable the structure of the support frame 20 to be maintained within a size range that is convenient for users to wear, the present embodiment makes full use of the installation space of the device body 10 and installs the reduction transmission mechanism 40 on the device body 10, which can be configured to be at least partially placed inside the device body 10, with the first end of the reduction transmission mechanism 40 fixedly connected to the output end, and the second end of the reduction transmission mechanism 40 installed on the support frame 20. In this way, when the fixed end and the output end of the driving mechanism move relative to each other, the speed of the output end will be slowed down by the reduction transmission mechanism 40 due to the existence of the reduction transmission mechanism 40, and because the reduction transmission mechanism 40 is connected between the output end and the support frame 20, the output end can push back the fixed end, thereby finally achieving the purpose of slowing down the speed of the fixed end and increasing the torque during movement, so as to reduce the risk of damage caused by excessive relative rotation speed between the device body 10 and the support frame 20, and improve the connection stability between the device body 10 and the support frame 20.

[0074] By implementing the above scheme, 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.

[0075] In addition, the driving mechanism is connected to the support frame 20 via a reduction transmission mechanism 40, so that the device body 10 can rotate at a uniform and stable speed, and obtain a larger torque during the rotation process of the device body 10, thereby improving the stability of the device body 10 during the rotation process, making the image captured by the camera module more stable and clear, and improving the user experience.

[0076] 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 reduction transmission mechanism 40 can be configured as a planetary reduction mechanism, a worm reduction mechanism, a cycloidal pinwheel reduction mechanism, a harmonic reduction mechanism, etc., and when the driving mechanism is a linear motion mechanism, the reduction mechanism can be configured as a linear reducer.

[0077] It should be noted that the electronic device can be used as a smart wearable device, such as the main body 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 holder 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.

[0078] 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.

[0079] Please continue to refer to Figure 1-Figure 2 , Figure 4-Figure 8A mounting cavity 13 is formed in the hollow of the device body 10. The mounting cavity 13 is used to provide mounting space for various functional modules and components in the electronic device. For example, the camera module, display screen and other modules in the smart watch are all mounted in the mounting cavity 13 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 13 and can form a matching relationship with the cavity wall of the mounting cavity 13, 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 13 and communicated through connecting wires to avoid 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 13 to the support frame 20, and the connection between the connecting wire and the module component is prevented from failing due to the relative movement between the device body 10 and the support frame 20.

[0080] In this embodiment, an opening 14 connected to the installation cavity 13 is opened on one side of the device body 10. The opening 14 is used to allow at least part of the output end or at least part of the reduction transmission mechanism 40 to extend from the installation cavity 13 to the outside of the device body 10 to connect with the support frame 20.

[0081] Please refer to Figure 5-Figure 7 Taking the above-mentioned opening 14 as an example of a solution for providing at least a portion of the reduction transmission mechanism 40 to extend from the mounting cavity 13 and be connected to the support frame 20, in this embodiment, the driving mechanism is entirely located in the mounting cavity 13, the first end of the reduction transmission mechanism 40 is arranged in the mounting cavity 13 and connected to the output end, and the second end of the reduction transmission mechanism 40 extends out of the device body 10 through the opening 14 and is installed on the support frame 20.

[0082] Here, because the second end of the reduction transmission mechanism 40 needs to extend from the opening 14 to the outside of the device body 10 to achieve connection with the support frame 20, 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 14 and the portion of the reduction transmission mechanism 40 extending from the opening 14, but dust, debris, liquids, etc. can easily enter the installation cavity 13 through the space gap between the opening 14 and the reduction transmission mechanism 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, etc., it can reduce foreign matter from entering the installation cavity 13 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 14 and the second end of the reduction transmission mechanism 40 are sealed together by a sealing component 141. The sealing component 141 can be configured as a sealing ring or a mechanical sealing structure. The outer side surface of the sealing component 141 is sealed together with the side wall of the opening 14, and the inner side surface of the sealing component 141 is sealed together with the reduction transmission mechanism 40, thereby preventing foreign objects from the external environment from moving through the space gap between the opening 14 and the reduction transmission mechanism 40 and entering the installation cavity 13, thereby effectively extending the service life of the electronic device.

[0083] In the above-mentioned embodiment where the sealing component 141 is a sealing ring, the sealing ring has a certain elastic reset performance, and the second end of the reduction transmission mechanism 40 is connected to the sealing ring. The outer circumference and the inner circumference of the sealing ring are respectively abutted against the side wall of the opening 14 and the reduction transmission mechanism 40. In addition to the waterproof and dustproof sealing function, it can also increase the friction between the reduction transmission mechanism 40 and the device body 10, so that the device body 10 can play a damping role when rotating relative to the support seat. In the process of relative movement between the reduction transmission mechanism 40 and the device body 10, the relative offset between the two can also be compensated, thereby improving the stability of the device body 10 during rotation.

[0084] In another embodiment, taking the above-mentioned opening 14 as an example of a scheme in which at least part of the output end is used to extend from the mounting cavity 13 and is connected to the support frame 20 through the reduction transmission mechanism 40, in the driving mechanism, the fixed end and at least part of the output end are located in the mounting cavity 13, and the output end at least partially extends out of the device body 10 through the opening 14 and is connected to the first end of the reduction transmission mechanism 40, and the second end of the reduction transmission mechanism 40 is connected to the support frame 20.

[0085] Similar to the above-mentioned embodiment, since the output end needs to at least partially extend from the opening 14 to the outside of the device body 10 and is connected to the support frame 20 through the reduction transmission mechanism 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 14 and the portion of the output end extending from the opening 14, but dust, debris, liquid, etc. can easily enter the installation cavity 13 through the space gap between the opening 14 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 foreign matter from entering the installation cavity 13 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 14 is sealed with the output end by a sealing component 141, and the sealing component 141 can be configured as a sealing ring or a mechanical sealing structure. The outer side surface of the sealing component 141 is sealed with the side wall of the opening 14, and the inner side surface of the sealing component 141 is sealed with the output end, thereby preventing foreign objects from the external environment from moving through the space gap between the opening 14 and the output end and entering the installation cavity 13, thereby effectively extending the service life of the electronic device.

[0086] In the above-mentioned embodiment where the sealing component 141 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 14 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 can play a damping role when rotating relative to the support seat, 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.

[0087] It should be understood that in the above-mentioned embodiment of setting the sealing component 141, the sealing component 141 can be set to at least one. The present embodiment preferably adopts an embodiment in which the driving mechanism is completely arranged in the installation cavity 13, and the second end of the reduction transmission mechanism 40 passes through the equipment body 10 through the opening 14 and a sealing component 141 is arranged between the side wall of the opening 14. Here, two sealing rings are arranged between the reduction transmission mechanism 40 and the opening 14, and the two sealing rings are in contact with each other, thereby further improving the sealing performance of the equipment body 10.

[0088] In the above-mentioned embodiment in which the sealing component 141 is provided, since the sealing component 141 increases the friction between the electronic device and the reduction transmission mechanism 40 or the output end of the driving mechanism to a certain extent, this also increases the burden of the driving mechanism in the working state, and there may be a situation where the driving force of the driving mechanism is insufficient, resulting in the inability of the device body 10 to rotate relative to the support frame 20. Here, this embodiment can effectively increase the torque of the driving mechanism by providing a reduction transmission mechanism 40 between the output end and the support frame 20, while ensuring that the device body 10 can rotate at a uniform and stable speed, and can also allow the driving force of the driving mechanism to overcome the friction generated between the device body 10 and the reduction transmission mechanism 40 or the output end due to the addition of the sealing component 141, so that the device body 10 can rotate normally under the drive of the driving mechanism.

[0089] Please continue to refer to Figure 1-Figure 4 On the basis of the above embodiment, the device body 10 includes a first housing 11 and a second housing 12. The second housing 12 is detachably connected to the first housing 11 and encloses an installation cavity 13. When the internal module components of the electronic device are disassembled and assembled, the first housing 11 and the second housing 12 of the device body 10 can be disassembled and separated, so that the installation cavity 13 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 13.

[0090] Furthermore, the opening 14 is formed in the first housing 11 or the second housing 12, and the opening 14 is directly processed on the first housing 11 or the second housing 12, so that the processing accuracy of the opening 14 can be well controlled, ensuring that the side wall of the opening 14 and the sealing component 141 have good sealing performance in the assembled state, and further allowing the assembly relationship between the sealing component 141 and the reduction transmission mechanism 40 or the output end to meet the sealing performance requirements of the electronic device. It is avoided that the opening 14 is formed by the first housing 11 and the second housing 12, and the opening 14 is deformed due to assembly strength, processing error, deformation, etc. between the first housing 11 and the second housing 12, thereby affecting the sealing performance between it and the sealing component 141.

[0091] As an optional implementation of this scheme, the driving mechanism can be further connected to the reduction transmission mechanism 40 through a transmission component, so as to further improve the stability of the rotation of the device body 10 during the operation of the driving mechanism. It can be understood that in the implementation of the electronic device as a smart wearable device, since the size of the smart wearable device is relatively small, the installation cavity 13 inside the device body 10 is also relatively small, and the reduction transmission mechanism 40 is limited by the installation space and cannot form a higher reduction ratio. Here, the reduction ratio between the driving mechanism and the reduction transmission mechanism 40 can also be increased by further arranging a transmission component between the driving mechanism and the reduction transmission mechanism 40, so that the rotation speed of the device body 10 meets the requirements of the product equipment.

[0092] Please refer to Figure 5-Figure 8 In one embodiment, a transmission shaft 50 is provided between the driving mechanism and the reduction transmission mechanism 40, the transmission shaft 50 defines a first rotation axis, the first end of the transmission shaft 50 is transmission-connected to the output end, and the second end of the transmission shaft 50 is connected to the first end of the reduction transmission mechanism 40. In the scheme in which the transmission shaft 50 is provided between the driving mechanism and the reduction transmission mechanism 40, since the transmission shaft 50 is transmission-connected to 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 sleeved with a transmission wheel (such as a friction wheel, a gear, etc.) that is transmission-matched with the output shaft of the electric motor.

[0093] In order to allow the transmission shaft 50 to be stably placed in the installation cavity 13 and play a role in transmitting the torque between the output end and the reduction transmission mechanism 40, a rotating shaft bracket 60 is also provided in the equipment body 10, and the rotating shaft bracket 60 is fixedly connected to the equipment body 10. In this embodiment, the first support arm 64 and the second support arm 65 are respectively extended outward on the opposite sides (or any two sides) of the rotating shaft bracket 60. When the rotating shaft bracket 60 is located in the installation cavity 13, it can be supported and fixedly installed on the equipment body 10 by the first support arm 64 and the second support arm 65. 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 rotating shaft bracket 60 is fixed to the device body 10 , that is, the rotating shaft bracket 60 is also relatively fixed to the fixed end of the driving mechanism, therefore, in this embodiment, the rotating shaft bracket 60 can also be regarded as a fixed end.

[0094] Please refer to Figure 5-Figure 7 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 13 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.

[0095] Please continue to refer to Figure 5-Figure 8 Based 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 support plate 51 can be arranged on the upper part of the shaft bracket 60. 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 maintains a good transmission relationship with the reduction transmission mechanism 40.

[0096] 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.

[0097] 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.

[0098] Please continue to refer to Figure 5-Figure 8In the embodiment in which a support plate 51 is provided, a limiting convex edge 511 is provided on the outer edge of the support plate 51 from the first end of the transmission shaft 50 to the second end thereof, and is arranged around the periphery of the transmission shaft 50. Correspondingly, a first limiting groove 66 is provided around the shaft hole 61 and is aligned with the limiting convex edge 511 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 511 is clearance-matched with the first limiting groove 66, 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.

[0099] Of course, utilizing the limiting principle of the above-mentioned embodiment, a first limiting groove 66 can also be recessed on the outer edge of the support plate 51, and correspondingly, a limiting ridge 511 is convexly provided on the shaft bracket 60. However, in the present embodiment, since the support plate 51 is relatively thin and its surface is not conducive to processing a groove, it is preferred to adopt an embodiment in which the support plate 51 is convexly provided with a limiting ridge 511.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] The above-mentioned embodiment provides a structure of a support plate 51 and a magnetic component to constrain the axial and radial degrees of 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 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.

[0105] 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 13 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 67 spaced around the shaft hole 61. The depth of the second limiting groove 67 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.

[0106] 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 13, 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.

[0107] 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 box 30 is provided on one side of the rotating shaft bracket 60 for supporting the piezoelectric motor. 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.

[0108] Please refer to Figure 5-Figure 8As a specific structural form of the reduction transmission mechanism 40, in the present embodiment, the reduction transmission mechanism 40 is a planetary reduction mechanism, which utilizes the mutual meshing between the driving gear 41, the driven gear 42, and the inner ring 43 arranged on the same horizontal plane to realize the transmission of torque. The planetary reduction mechanism has a compact structure, a small return clearance and high precision, a long service life, and can meet the application in a small installation space. In addition, the planetary reduction mechanism can output a large torque, which can solve the technical problem of insufficient output torque of the driving mechanism due to the addition of the sealing component 141, the magnetic component, etc., which increases the burden on the driving mechanism.

[0109] Specifically, the reduction transmission mechanism 40 includes a driving gear 41, a driven gear 42 and an inner ring gear 43. The driving gear 41 can also be understood as the sun gear in the planetary reduction mechanism. The driving gear 41 serves as the first end of the reduction transmission mechanism 40 and is transmission-connected to the output end. Correspondingly, the driven gear 42 can also be understood as the planetary gear in the planetary reduction mechanism. The driven gear 42 is installed on one side of the driving gear 41 and meshes with the driving gear 41 for transmission. The inner ring gear 43 is used to cooperate with the driving gear 41 to constrain the moving path of the driven gear 42. It is fixedly connected to the device body 10 in the electronic device, and in an embodiment in which the inner ring gear 43 is provided with a transmission shaft 50 and a rotating shaft bracket 60 in the device body 10, the inner ring gear 43 is fixedly connected to the rotating shaft bracket 60. The inner gear ring 43 is arranged around the outer periphery of the driving gear 41, and a space gap is formed between the inner gear ring 43 and the driving gear 41 for the driven gear 42 to be arranged. The opposite sides of the driven gear 42 are respectively meshed with the driving gear 41 and the inner gear ring 43, so that the driven gear 42 is driven by the driving gear 41 and the inner gear ring 43 cooperates with the driving gear 41 to constrain and limit the driven gear 42, so that the driven gear 42 moves around the rotation axis (first rotation axis) of the driving gear 41.

[0110] In one embodiment, a plurality of driven gears 42 may be provided between the inner gear ring 43 and the driving gear 41 to improve the stability of the reduction transmission mechanism 40 and the torque output. In order to allow the second end of the reduction transmission mechanism 40 to form a coaxial or nearly coaxial assembly relationship with the first rotation axis, a transmission member 44 is provided between each driven gear 42 and the support seat. The transmission member 44 serves as the second end of the reduction transmission mechanism 40, one end of which is fixedly connected to each driven gear 42, and the other end of which forms a coaxial relationship with the first rotation axis (the rotation axis of the driving gear 41) and is circumferentially fixed to the support frame 20.

[0111] Through the above arrangement, during the operation of the driving mechanism, the transmission shaft 50 will rotate relative to the rotating shaft bracket 60 under the drive of the driving mechanism, and drive the driving gear 41 to rotate. During this process, the driving gear 41 drives the driven gear 42 to rotate around the first rotation axis, and revolves along the center according to the trajectory of the inner gear ring 43, and finally drives the transmission member 44 through the driven gear 42 to transmit the force to the support seat. However, in the application of electronic devices as supporting wearable devices, the support frame 20 is generally in a relatively fixed position with the user. At this time, the force applied to the support frame 20 will be transmitted along the transmission member 44, the driven gear 42 and the driving gear 41 in turn, and finally push the rotating shaft bracket 60 to drive the inner gear ring 43 and the device body 10 to rotate around the first rotation axis to achieve deceleration.

[0112] 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. 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 relatively fixed in the direction around the first rotation axis, that is, when the device body 10 rotates around the first rotation axis, the device body 10 will drive the first rotating shaft base 70 to move together. To achieve this purpose, the first rotating shaft base 70 needs to be set as a structural form that is rotatably connected to the support frame 20 around the first rotation axis, so that the first rotating shaft base 70 can rotate relative to the support frame 20 together with the device body 10.

[0113] Furthermore, 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 second rotating axis. Here, the first rotating axis and the second rotating axis are perpendicular to each other. In this embodiment, taking the support frame 20 placed horizontally as an example, the second rotating axis and the horizontal plane are parallel to each other, while the first rotating 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 second rotating axis, so that the device body 10 can be stacked on the support frame 20 (such as Figure 1-Figure 2 , Figure 5 ), or erected on the support frame 20 along the first rotation axis direction (as shown Figure 3-Figure 4 , Figure 6 As shown), when the device body 10 is in an upright state, the device body 10 can rotate around the first rotation axis, thereby achieving the purpose of changing the orientation of the device body 10.

[0114] It is understandable that the process of the device body 10 rotating around the second rotation 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 of this embodiment around the second rotation axis is configured to rely on human power. In order to achieve self-locking of the device body 10 on the second rotation 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 of the second rotation axis without the action of external force.

[0115] 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.

[0116] In the above scheme, the opening 14 of the equipment body 10 is opened on the bottom of the avoidance groove 16 away from its groove mouth, and the transmission member 44 extends into the avoidance groove 16 through the opening 14 and is connected to the support frame 20. In order to avoid the transmission member 44 from affecting the movement of the equipment body 10 on the second rotation axis, the transmission member 44 and the support frame 20 also adopt a rotationally matched connection method, and the rotation axis between the transmission member 44 and the support frame 20 is coaxial with the second rotation axis.

[0117] Based on the above-mentioned 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 connection between the reduction transmission mechanism 40 and the support frame 20, please refer to Figure 5-Figure 8The electronic device also includes a second rotating shaft base 80, which is fixedly connected to the support frame 20, and the second rotating shaft base 80 is fixedly connected to the second end (transmission member 44) of the reduction transmission mechanism 40 around the first rotation axis, that is, the second rotating shaft base 80 and the reduction transmission mechanism 40 do not have the ability to rotate relative to each other around the first rotation axis, and the second rotating shaft base 80 is rotationally connected to the second end (transmission member 44) of the reduction transmission mechanism 40 around the second rotation axis. While ensuring that the device body 10 is upright on the support frame 20, that is, the reduction transmission mechanism 40 is on the first rotation axis, the second rotating shaft base 80 and the reduction transmission mechanism 40 can transmit circumferential force without affecting the movement of the device body 10 around the second rotation axis, thereby avoiding interference between the second rotating shaft base 80 and the reduction transmission mechanism 40 on the second rotation axis.

[0118] Through the above-mentioned embodiment, the second end (transmission member 44) of the reduction transmission mechanism 40 can first be matched with the second rotating shaft base 80, and then the equipment 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 equipment body 10 is close to the support frame 20, the operating space between the two is narrow, which makes it difficult to assemble the reduction transmission mechanism 40 and the support frame 20.

[0119] Taking the application of electronic devices in smart watches as an example, in this embodiment, the device body 10 can be switched around the second rotation axis between the position of being stacked on the support frame 20 or standing on the support frame 20, so that the device body 10 as the watch body can be in a state of being stacked on the support frame 20 when not in use, reducing the volume of the device body 10 on the support frame 20 in the vertical direction. When the user needs to perform operations such as video recording, video calls, and shooting of foreground and background, the device body 10 can be flipped around the second rotation axis relative to the support frame 20 to stand upright on the support frame 20, and rotate around the first rotation axis relative to the support frame 20 under the drive of the driving mechanism to change the orientation of the device body 10, so that the camera module set on the device body 10 can also change its shooting direction together with the adjustment of the device body 10 to meet the state requirements in different usage scenarios.

[0120] 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 .

[0121] In this embodiment, please continue to refer to Figure 1-Figure 8In 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 first rotating 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 of 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 reduction transmission mechanism 40, the first rotating shaft base 70 is provided with a avoiding hole 71, and correspondingly, the second rotating shaft base 80 at least partially passes through the avoiding hole 71 to the upper part of the first rotating shaft base 70 and is rotationally connected with the second end (transmission member 44) of the reduction transmission mechanism 40.

[0122] 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.

[0123] In the above 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 process, resulting in an excessively large friction coefficient between the two, thereby affecting the rotation of the equipment body 10 around the first rotation axis. To solve this problem, a second rolling component 81 is provided between the first shaft base 70 and the second shaft base 80. The provision of the second rolling component 81 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 81. In this embodiment, the first shaft base 70 is supported on the second shaft base 80 through the second rolling component 81. 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.

[0124] Similarly, in order to avoid the existence of the second rolling component 81 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 84 are provided on the second rotating shaft base 80 and are spaced around the avoiding hole 71. The depth of the third limiting groove 84 needs to be set to be smaller than the second rolling component 81, 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 81, so that the second rolling component 81 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.

[0125] Please continue to refer to Figure 5-Figure 8 A avoidance hole 71 is opened on the first rotating shaft base 70, and a first connecting member 82 is fixedly arranged on the second rotating shaft base 80, which passes through the avoidance hole 71 to the upper part of the first rotating shaft base 70. The first connecting member 82 is connected to the reduction transmission mechanism 40 through the second connecting member 83, and the second connecting member 83 is provided with two spaced connecting parts 831 at one end close to the first connecting member 82. The first connecting member 82 is at least partially placed between the two connecting parts 831, and is rotatably connected to the two connecting parts 831 around the second rotating axis through the rotating shaft, ensuring that a stable assembly relationship is formed between the first connecting member 82 and the second connecting member 83, and the modular component structure facilitates the disassembly and assembly of the electronic equipment.

[0126] It is worth mentioning that in the implementation example in which the reduction transmission mechanism 40 is a planetary reduction mechanism, the transmission member 44 can be configured as a coupling, and the coupling of the transmission member 44 is connected to the second connecting member 83 .

[0127] As shown in Figure 1- Figure 4 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.

[0128] 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 the strap as a wearable component. The device body 10 as a watch body can be swung relative to the support frame 20 around the second rotation 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 first rotation 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 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 to meet the needs of different users in different usage scenarios.
