[0041] With the rapid progress of technology, smartwatches have quietly integrated into people's daily lives and become indispensable smart companions. Users' requirements for the functionality and aesthetics of smartwatches are also constantly increasing. Technological innovation has become particularly important, especially the refined optimization of the internal design of smartwatches, which has become the key.

[0042] Currently, smartwatches can achieve multiple functions. For example, by adopting the optical knob technology, through its built-in photoelectric encoder, the mechanical rotation of the knob is converted into an electrical signal to achieve the control of various functions of the watch. Another example is through the design of a combination of a motor and an eccentric wheel. The motor drives the eccentric wheel to rotate, and the centrifugal force principle is used to keep the motor in a continuous unbalanced state, thereby realizing the vibration feedback function of the watch. In this way, multiple functions of the smartwatch can be achieved, enhancing the user's interaction experience. However, since each function requires the setting of a corresponding functional module, the internal structure of the smartwatch is complex and occupies a relatively large space, which is not conducive to the assembly of the smartwatch and also not conducive to the miniaturization design of the smartwatch.

[0043] Based on this, this application discloses a smartwatch that can realize the recognition function of knob operation without additionally setting a photoelectric sensor. Under the condition of realizing the same function, the use of components is reduced, achieving the purpose of miniaturizing the smartwatch.

[0044] The technical solutions of this application will be further described below in conjunction with embodiments and the accompanying drawings.

[0045] Please refer to Figure 1 , Figure 1It is a partial structural schematic diagram of a perspective of a smart watch disclosed in an embodiment of the present application. A smart watch 100 provided by an embodiment of the present application includes a housing 1, a motor assembly 2, and a knob component 3. An accommodation space 11 is formed inside the housing 1. A circuit board (not shown) is provided in the accommodation space 11. The housing 1 is provided with a first through hole 111 communicating with the accommodation space 11. The motor assembly 2 is disposed in the accommodation space 11. The motor assembly 2 is electrically connected to the circuit board. One end of the knob component 3 passes through the first through hole 111 and is connected to the output shaft 23 of the motor assembly 2. In this way, the motor assembly 2 can be configured to rotate under the control of the circuit board to drive the housing 1 to vibrate. Or, the motor assembly 2 can be configured to generate an electrical signal to the circuit board when the knob component 3 rotates relative to the first through hole 111 to drive the output shaft 23 to rotate, so that the circuit board processes information according to the electrical signal.

[0046] That is to say, the motor assembly 2 can generate a voltage signal driven by the knob component 3 and be read by the circuit board. The circuit board identifies the read signal to implement the corresponding operation function. In addition, the motor assembly 2 can also implement the vibration function of the smart watch 100 when the circuit board outputs a voltage signal. In this way, by using the motor assembly 2, the structural reuse of the motor assembly 2 can be realized. While retaining the vibration function of the motor assembly 2 itself, without the need to additionally set an optical sensor, the mechanical rotation of the knob component 3 can be converted into an electrical signal, which is then identified by the circuit board and used for information processing.

[0047] It can be understood that the information processing by the circuit board according to the electrical signal may include functions such as volume adjustment, page turning, picture zooming in or out of the smart watch 100, and can also implement functions such as accelerating scrolling or adjusting values, as well as implementing more precise selection or adjustment functions.

[0048] Optionally, the motor assembly 2 can be bonded to the bottom surface of the housing 1 with glue or double-sided tape, so as to directly connect the motor assembly 2 to the housing 1 of the smart watch 100, making the vibration sensation transmission more direct and effective, thereby effectively improving the vibration feedback effect of the smart watch 100.

[0049] In some embodiments, the motor assembly 2 includes any one of an eccentric motor, a linear motor, and a flat motor, and this embodiment does not limit this.

[0050] Optionally, taking the eccentric motor as an example of the motor assembly 2, the motor assembly 2 includes a motor body 21, an eccentric wheel 22 and an output shaft 23. The motor body 21 is connected to the circuit board, the output shaft 23 is connected to the motor body 21, and the eccentric wheel 22 is sleeved on the output shaft 23. When the motor body 21 is configured to be controlled by the circuit board, the circuit board outputs an electrical signal to the motor body 21, thereby driving the output shaft 23 of the motor body 21 to rotate. At this time, the eccentric wheel 22 sleeved on the output shaft 23 rotates. Due to the action of centrifugal force, the output shaft 23 connected to the eccentric wheel 22 transmits the centrifugal force to the motor body 21, causing the motor body 21 to be in a continuous unbalanced state, thereby driving the housing 1 to vibrate to achieve the vibration feedback function of the smart watch 100.

[0051] Optionally, the eccentric wheel 22 is sleeved on the output shaft 23. The connection manner between the eccentric wheel 22 and the output shaft 23 can be any one of welding, glue bonding, and key connection. This embodiment does not limit this. Exemplarily, when the connection manner between the eccentric wheel 22 and the output shaft 23 is a welded connection, the connection manner between the output shaft 23 and the eccentric wheel 22 is simple and the connection reliability is better. When the connection manner between the eccentric wheel 22 and the output shaft 23 is glue bonding, the connection manner is also relatively simple and does not require special equipment to implement, which is beneficial to simplifying the connection process between the eccentric wheel and the output shaft. When the connection manner between the eccentric wheel 22 and the output shaft 23 is a key connection, the output shaft 23 can provide reliable rotation transmission for the eccentric wheel 22 and is easier to maintain and replace than welding and glue bonding.

[0052] Please refer to again Figure 1 , in some embodiments, the motor assembly 2 includes a motor body 21 and an output shaft 23. A first power connection part 211 and a second power connection part 212 are provided on the motor body 21, and the second power connection part 212 is spaced from the first power connection part 211. Among them, both the first power connection part 211 and the second power connection part 212 are electrically connected to the circuit board. In this way, the circuit board can output an electrical signal to the motor body 21 to control the motor body 21, or the circuit board receives the electrical signal sent by the motor body 21. Thus, when the smart watch 100 needs to output a vibration feeling, the circuit board can output an electrical signal to the motor body 21 to make the motor body 21 vibrate to make the housing 1 vibrate, thereby achieving the vibration feedback function of the smart watch 100. When the motor assembly 2 is in a state other than when it needs to output a vibration feeling, the circuit board can continuously receive the electrical signal sent by the motor body 21, so that the smart watch 100 can respond to the operation of the knob component 3. Therefore, the smart watch 100 can realize the vibration function and knob recognition function of the smart watch 100 by using the motor assembly 2 and the knob component 3, realize the reuse of components, thereby reducing the use of components, reducing the manufacturing cost and achieving the purpose of miniaturized design.

[0053] Optionally, when one of the first power connection part 211 and the second power connection part 212 is configured to output a high level under the control of the circuit board and the other is configured to output a low level under the control of the circuit board, at this time, the smart watch 100 is in a locked screen state or a state where a vibration sensation needs to be output. In this case, the motor assembly 2 can generate vibration by itself under the control of the circuit board, thereby driving the housing 1 to vibrate, that is, the smart watch 100 can output a vibration sensation under the control of the circuit board. It can be understood that the state where a vibration sensation needs to be output can be a message, an incoming call notification reminder, an alarm reminder, the timer reaching the end time, a sedentary reminder, a tactile feedback when operating the screen or a button, etc. In the above cases, the smart watch 100 can output a vibration sensation, thereby serving as a reminder and feedback function of the smart watch 100.

[0054] Optionally, when the first power connection part 211 and the second power connection part 212 are configured such that when the knob member 3 rotates relative to the first through hole 111 to drive the output shaft 23 to rotate, one of the first power connection part 211 and the second power connection part 212 outputs a high level to the circuit board, and the other of the first power connection part 211 and the second power connection part 212 outputs a low level to the circuit board, thereby controlling the function corresponding to the electrical signal that the smart watch 100 responds to.

[0055] Optionally, when the first power connection part 211 and the second power connection part 212 are configured such that when the knob member 3 rotates relative to the first through hole 111 to drive the output shaft 23 to rotate, one of the first power connection part 211 and the second power connection part 212 outputs a high level to the circuit board, and the other of the first power connection part 211 and the second power connection part 212 outputs a low level to the circuit board. At this time, the voltage direction generated by the first power connection part 211 and the second power connection part 212 is adapted to the rotation direction of the knob member 3, and the voltage magnitude generated by the first power connection part 211 and the second power connection part 212 is adapted to the rotation speed of the knob member 3. Thus, the rotation direction and rotation speed of the knob member 3 correspond to the voltage direction and voltage magnitude generated by the first power connection part 211 and the second power connection part 212, thereby converting the mechanical rotation of the knob member 3 into an electrical signal, and then the circuit board identifies the voltage direction and voltage magnitude, and further responds to the corresponding function of the smart watch 100.

[0056] For example, when the mechanical rotation of the knob member 3 is converted into an electrical signal, the rotation direction of the knob member 3 corresponds to the voltage direction generated by the first power connection part 211 and the second power connection part 212, and the circuit board identifies the voltage direction, thereby realizing functions such as volume adjustment, page turning, picture magnification or reduction of the smart watch 100. In addition, the rotation speed of the knob member 3 corresponds to the voltage magnitude generated by the first power connection part 211 and the second power connection part 212, and the circuit board identifies the voltage magnitude, so that rapid rotation of the knob member 3 can realize functions such as accelerating scrolling or adjusting values, while slow rotation of the knob member 3 can realize more precise selection or adjustment.

[0057] It can be understood that, in addition to the aforementioned voltage direction generated by the first power connection part 211 and the second power connection part 212 being adapted to the rotation direction of the knob component 3, and the voltage magnitude generated by the first power connection part 211 and the second power connection part 212 being adapted to the rotation speed of the knob component 3, the first power connection part 211 and the second power connection part 212 can also be other examples, for example, the voltage direction generated by the first power connection part 211 and the second power connection part 212 is adapted to the rotation direction of the knob component 3, or the voltage magnitude generated by the first power connection part 211 and the second power connection part 212 is adapted to the rotation speed of the knob component 3, and the embodiments of the present application are not limited to this.

[0058] See also Figure 2 , Figure 2 1 is a partial structural diagram of the smart watch disclosed in the embodiment of the present application from another perspective. In some embodiments, the smart watch 100 further includes a support component 4, which is disposed on the housing 1 and connected to the knob component 3. The knob component 3 can rotate relative to the support component 4. The support component 4 is used to support the knob component 3, support the knob component 3, disperse the radial load generated when the knob component 3 rotates, avoid the knob component 3 from breaking, and extend the service life of the knob component 3.

[0059] Optionally, the smart watch 100 further includes a rotating bearing component (not shown), the rotating bearing component includes an inner ring (not shown) and an outer ring (not shown), the outer ring is fixedly arranged with the support component 4, the inner ring is fixedly arranged with the knob component 3, and the inner ring and the outer ring are rotatably connected, so that the knob component 3 can rotate relative to the support component 4, thereby, the rotating bearing component can bear the radial load of the knob component 3, limit the knob component 3 so that it can only rotate, and control its axial and radial movement. In addition, the rotating bearing component connects the support component 4 and the knob component 3, so that the friction between the support component 4 and the knob component 3 is reduced, thereby reducing the wear and heat of the knob component 3, and then effectively extending the overall service life of the device.

[0060] Optionally, the knob component 3 includes a shaft portion 31 and a screw cap portion 32, the shaft portion 31 is connected to the screw cap portion 32, the shaft portion 31 is connected to the output shaft 23, the screw cap portion 32 rotates to drive the output shaft 23 to rotate, the motor assembly 2, the support component 4 and the screw cap portion 32 are sequentially arranged along the first direction F1, one end of the support component 4 is arranged on the bottom surface of the housing 1, and the other end of the support component 4 is provided with a supporting groove penetrating the end surface of the support component 4, and the supporting groove is configured to support the shaft portion 31. Among them, the first direction F1 can be a through direction along the first through hole 111.

[0061] Optionally, the housing 1 is thickened at a position corresponding to the first through hole 111, which can increase the strength and stiffness of the housing 1 when stressed, bear the radial load generated when the knob component 3 rotates, reduce the deformation amount of the housing 1 at the first through hole 111, and reduce the risk of the housing 1 breaking.

[0062] As Figure 3 shown, the multiplexing of the motor assembly 2 of the smart watch 100 of the present application in different states will be described below.

[0063] In one example, as Figure 3 (a) in shows the flowchart when the smart watch 100 needs to output a vibration feeling. When the smart watch 100 is in the locked screen state or the lit screen state and needs to give message, incoming call notification reminder, alarm reminder, timer reaches the end time, sedentary reminder, tactile feedback when operating the screen or buttons, one of the first power connection part 211 and the second power connection part 212 outputs a high level under the control of the circuit board, and the other outputs a low level under the control of the circuit board. After the motor assembly 2 receives the voltage signal, it vibrates itself, thereby driving the housing 1 to vibrate. At this time, the smart watch 100 outputs a vibration feeling to remind the user.

[0064] In another example, as Figure 3 (b) in shows the flowchart when the user rotates the knob component. When the user is listening to music and needs to adjust the volume through the smart watch 100, the user can rotate the knob component 3 clockwise or counterclockwise, so that the knob component 3 drives the output shaft 23 of the motor assembly 2 to rotate clockwise or counterclockwise. At this time, one of the first power connection part 211 and the second power connection part 212 outputs a high level to the circuit board, and the other outputs a low level to the circuit board, and the voltage directions generated by the first power connection part 211 and the second power connection part 212 are adapted to the rotation direction of the knob component 3. Thus, the circuit board adjusts the volume size by identifying the voltage direction. Or, when the user needs to quickly scroll the page to search for information, the user can quickly rotate the knob component 3, so that the knob component 3 drives the output shaft 23 of the motor assembly 2 to rotate quickly. At this time, one of the first power connection part 211 and the second power connection part 212 outputs a high level to the circuit board, and the other outputs a low level to the circuit board. The voltage magnitudes generated by the first power connection part 211 and the second power connection part 212 are adapted to the rotation speed of the knob component 3. The circuit board can adjust the page scrolling speed of the smart watch 100 by identifying the voltage magnitude.

[0065] Please refer to Figure 4 , Figure 4It is a schematic structural diagram of the smart watch disclosed in the embodiments of the present application. In some embodiments, the smart watch 100 further includes a housing 6. The housing 6 and the housing 1 enclose the internal space of the smart watch 100. The housing 1 and the housing 6 are assembled and connected to each other. The direct connection between the housing 6 and the housing 1 can more directly sense the vibration and improve the vibration feedback effect. Optionally, the housing 1 can be used as the bottom case of the smart watch 100, and the housing 6 can be used as the housing 6 of the smart watch 100. Thus, the housing 6 can protect the internal structure of the smart watch 100, which is beneficial to the waterproof and dustproof design of the smart watch 100.

[0066] Furthermore, the smart watch 100 further includes a watch band 5. The watch band 5 may include a first watch band and a second watch band. The first watch band and the second watch band are symmetrically connected to both sides of the housing 6, so as to realize wearing the smart watch 100 on the human wrist.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
