Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a watch. Background Art

[0002] As smartwatches become increasingly versatile, they are becoming increasingly popular. Currently, smartwatches can simulate the feel of a mechanical watch by rotating a button to drive an internal motor, providing users with a similar user experience to a mechanical watch. However, rotating a button to drive the motor to simulate the mechanical feel, as the mechanical feel is transmitted from the inside out, consumes a lot of power. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a watch that can solve the problem of high power consumption caused by the watch in the related art simulating the mechanical feel by rotating the button to drive the motor.

[0004] An embodiment of the present application provides a watch, comprising a housing assembly, a rotating assembly, a screen assembly, and a circuit board assembly, wherein the housing assembly and the screen assembly enclose a receiving space, and the circuit board assembly is located in the receiving space;

[0005] The rotating assembly includes a first ratchet ring, a first pawl and a first rotating shaft. The first ratchet ring is rotatably arranged on the outside of the shell assembly. The inside of the first ratchet ring is provided with a first tooth structure. The first pawl and the first rotating shaft are arranged on the inside of the first ratchet ring. The first end of the first pawl is engaged with the first tooth structure, and the second end of the first pawl is rotatably connected to the first rotating shaft.

[0006] The watch provided in the embodiment of the present application includes a first ratchet ring, a first pawl and a first pawl shaft, and the inner side of the first ratchet ring is provided with a first toothed structure. When the user rotates the first ratchet ring, since the first toothed structure on the inner side of the first ratchet ring is engaged and connected with the first pawl, the first ratchet ring is not completely fixed, but can rotate relative to the watch case, and during the rotation of the first ratchet ring, the engagement of the first toothed structure with the first pawl causes the first pawl to hit the first toothed structure on the first ratchet ring and generate vibration, thereby achieving a mechanical segmentation feeling when rotating the first ratchet ring, and the rotation of the first ratchet ring is manually rotated by the user, which can bring the user the most intuitive and delay-free mechanical segmentation feeling. Compared with the related art that requires a driving motor to achieve a mechanical sense, the watch provided in the embodiment of the present application can achieve a mechanical segmentation feeling by rotating the first ratchet ring, without consuming electricity, and the mechanical segmentation feeling is more realistic.

[0017] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0019] The embodiment of the present application provides a watch, for example, the watch can be a smart watch. The watch provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0020] Please refer to Figures 1 to 10 The watch provided in the embodiment of the present application includes a housing assembly 10, a rotating assembly 20, a screen assembly 30 and a circuit board assembly 40. The housing assembly 10 and the screen assembly 30 enclose a receiving space 50, and the circuit board assembly 40 is located in the receiving space 50.

[0021] The rotating assembly 20 includes a first ratchet ring 211, a first pawl 221 and a first rotating shaft 231. The first ratchet ring 211 is rotatably arranged on the outside of the shell assembly 10. The inside of the first ratchet ring 211 is provided with a first tooth structure 2113. The first pawl 221 and the first rotating shaft 231 are arranged on the inside of the first ratchet ring 211. The first end of the first pawl 221 is engaged with the first tooth structure 2113, and the second end of the first pawl 221 is rotatably connected to the first rotating shaft 231.

[0022] It should be noted that, in some embodiments, the housing assembly 10 generally includes a watch case 11, which may also be referred to as a frame or a middle frame. Figure 1 and Figure 2 As shown, the watch case 11 includes an annular side wall, and the first ratchet ring 211 is sleeved on the annular side wall, so that the first ratchet ring 211 can be rotated.

[0023] The watch provided in the embodiment of the present application includes a first ratchet ring 211, a first pawl 221, and a first pawl shaft 231. A first toothed structure 2113 is provided on the inner side of the first ratchet ring 211. When a user rotates the first ratchet ring 211, the first toothed structure 2113 on the inner side of the first ratchet ring 211 engages with the first pawl 221, so the first ratchet ring 211 is not completely fixed but is able to rotate relative to the watch case 11. Furthermore, during the rotation of the first ratchet ring 211, the engagement of the first toothed structure 2113 with the first pawl 221 causes the first pawl 221 to strike the first toothed structure 2113 on the first ratchet ring 211, generating vibrations. This creates a mechanical click feeling when rotating the first ratchet ring 211. Since the rotation of the first ratchet ring 211 is manually performed by the user, the user can experience the most intuitive and delay-free mechanical click feeling. Compared to the related art that requires a motor to be driven to achieve a mechanical feel, the watch provided in the embodiment of the present application can achieve a mechanical click feel by simply rotating the first ratchet ring 211, without consuming electricity, and the mechanical click feel is more realistic.

[0024] Please refer to Figures 2 to 5The watch provided in the embodiment of the present application also includes a second ratchet ring 212, a second pawl 222 and a second rotating shaft 232; the second ratchet ring 212 is rotatably arranged on the outside of the shell assembly 10, and the inner side of the second ratchet ring 212 is provided with a second tooth structure 2123, the second pawl 222 and the second rotating shaft 232 are arranged on the inner side of the second ratchet ring 212, the first end of the second pawl 222 is engaged with the second tooth structure 2123, and the second end of the second pawl 222 is rotatably connected to the second rotating shaft 232.

[0025] In which, the first ratchet ring 211 rotates along the first rotation direction S1 relative to the first pawl 221, and the watch performs a first operation in response to the rotation of the first ratchet ring 211 along the first rotation direction S1; the second ratchet ring 212 rotates along the second rotation direction S2 relative to the second pawl 222, and the second rotation direction S2 is opposite to the first rotation direction S1, and the watch performs a second operation in response to the rotation of the second ratchet ring 212 along the second rotation direction S2.

[0026] In the embodiment of the present application, the first ratchet ring 211 is meshed with the first pawl 221 via a first toothed structure 2113 disposed on its inner side, and the second ratchet ring 212 is meshed with the second pawl 222 via a second toothed structure 2123 disposed on its inner side. When a user rotates the first ratchet ring 211 in a first rotational direction (e.g., counterclockwise), the first pawl 221 strikes the first toothed structure 2113 disposed on its inner side, generating vibrations, thereby providing the user with a sense of mechanical click in the first rotational direction. When a user rotates the second ratchet ring 212 in a second rotational direction (e.g., clockwise), the second pawl 222 strikes the second toothed structure 2123 disposed on its inner side, generating vibrations, thereby providing the user with a sense of mechanical click in the second rotational direction. Furthermore, the arrangement of the first ratchet ring 211 and the second ratchet ring 212 allows the user to experience a sense of mechanical click in different directions, further enhancing the user experience of the watch.

[0027] like Figure 5 As shown, the first pawl shaft 231 and the second pawl shaft 232 can be arranged in parallel, with the first pawl shaft 231 being used to secure and support the first pawl 221, and the second pawl shaft 232 being used to secure and support the second pawl shaft 232. It is understood that when the first ratchet ring 211 rotates in the first rotational direction, it causes the first pawl 221 to swing a certain amount in the first rotational direction, and when the second ratchet ring 212 rotates in the second rotational direction, it causes the second pawl 222 to swing a certain amount in the second rotational direction. Since the first rotational direction is opposite to the second rotational direction, the first pawl 221 and the second pawl 222 also swing in opposite directions, thereby preventing the first pawl 221 and the second pawl 222 from colliding.

[0028] It should be noted that if Figure 5 As shown, the first tooth structure 2113 and the second tooth structure 2123 are oriented in opposite directions, or in other words, the flat sides of the first tooth structure 2113 and the second tooth structure 2123 are arranged in opposite directions, so that the first ratchet ring 211 can only rotate in the first rotation direction, and the second ratchet ring 212 can only rotate in the second rotation direction, which ensures the different rotation directions of the first ratchet ring 211 and the second ratchet ring 212 and avoids collision between the first pawl 221 and the second pawl 222.

[0029] In the embodiment of the present application, when the first ratchet ring 211 rotates relative to the first pawl 221 in a first rotational direction, the watch performs a first operation in response to the rotation of the first ratchet ring 211. The first operation includes, but is not limited to: increasing (or decreasing) the volume, playing the next (or previous) song, playing the next (or previous) video, locking (or lighting) the watch screen, etc. When the second ratchet ring 212 rotates relative to the second pawl 222 in a second rotational direction, the watch performs a second operation in response to the rotation of the second ratchet ring 212. The second operation includes, but is not limited to: decreasing (or increasing) the volume, playing the previous (or next) song, playing the previous (or next) video, lighting (or locking) the watch screen, etc. It is understandable that the first and second operations may also be other possible situations, which are not specifically limited in this application. Furthermore, while the user experiences the mechanical sense of movement by rotating the first ratchet ring 211 or the second ratchet ring 212, they can also control the watch, effectively improving the user experience of the watch.

[0030] Please refer to Figure 2 and Figure 3The case assembly 10 includes a watch case 11 having a first case portion 101 and a second case portion 102 connected thereto. The first case portion 101 and the second case portion 102 are stacked along a first direction (which can be understood as a direction perpendicular to the watch screen). In a radial direction perpendicular to the first direction, the second case portion 102 extends outward relative to the first case portion 101 to form a bearing portion 1021. If the watch only includes a first ratchet ring 211, the first ratchet ring 211 is rotatably mounted on the first case portion 101, and the bearing portion 1021 supports the first ratchet ring 211. If the watch includes a first ratchet ring 211 and a second ratchet ring 212, the first ratchet ring 211 and the second ratchet ring 212 are stacked one above the other, and the bearing portion 1021 supports the second ratchet ring 212. The first ratchet ring 211 is stacked on the second ratchet ring 212, and the first ratchet ring 211 and the second ratchet ring 212 are rotatable relative to each other. Furthermore, by providing an outward-extending bearing portion 1021 on the second shell portion 102, it can be used to carry the first ratchet ring 211 or the first ratchet ring 211 and the second ratchet ring 212, which makes it more convenient for users to rotate the first ratchet ring 211 and the second ratchet ring 212 and helps to improve the aesthetics of the watch.

[0031] Optionally, a plurality of supporting protrusions are provided on one side of the bearing portion 1021 facing the second ratchet ring 212 , for supporting the second ratchet ring 212 , thereby helping to ensure the stability of the second ratchet ring 212 and the first ratchet ring 211 .

[0032] Optionally, the housing assembly further includes a bottom cover 12. The bottom cover 12 and the screen assembly 30 are respectively disposed on opposite sides of the watch case 11 to enclose a receiving space 50. The bottom cover 12 is connected to the second housing portion 102, and the screen assembly 30 is connected to the first housing portion 101. Thus, the connection between the bottom cover 12, the second housing portion 102, the first housing portion 101, and the screen assembly 30 forms the receiving space 50 of the watch. This receiving space 50 is a sealed space, thereby effectively ensuring the safety and service life of the circuit board assembly 40 housed therein, thereby helping to increase the service life of the watch.

[0033] Optionally, the first housing portion 101 is provided with a first opening 1010, through which the first pawl 221 and the first toothed structure 2113 engage with each other. The second pawl 222 and the second toothed structure 2123 also engage with each other through the first opening 1010. Furthermore, the first pawl 221 and the second pawl 222 can be disposed within the receiving space 50 and can pass through the first opening 1010 to respectively engage with the first toothed structure 2113 and the second toothed structure 2123 sleeved on the first housing portion 101, thereby ensuring that the first ratchet ring 211 and the second ratchet ring 212 can rotate relative to the housing assembly 10, providing the user with a more realistic mechanical segmentation experience.

[0034] Alternatively, see Figure 4 and Figure 8 The housing assembly 10 includes a baffle 13 that divides the receiving space 50 into a first receiving space 501 and a second receiving space 502 . The circuit board assembly 40 is received in the first receiving space 501 , and the first pawl 221 and the first rotating shaft 231 are disposed in the second receiving space 502 .

[0035] It can be understood that the first shell part 101 is provided with a first opening 1010, and in order to protect the circuit board assembly 40 in the watch, a baffle 13 can be set to separate the receiving space 50 into a first receiving space 501 and a second receiving space 502 that are independent of each other, wherein the first opening 1010 of the first shell part 101 passes through the second receiving space 502 and the outer space of the first shell part 101, and thus the first receiving space 501 can be a completely sealed space, thereby preventing water, dust and other impurities from entering the first receiving space 501, effectively ensuring the safety and service life of the circuit board assembly 40 in the first receiving space 501.

[0036] It is understood that in some embodiments, the watch may further include a second ratchet ring 212, a second pawl 222, and a second rotating shaft 232. In this case, the second pawl 222 and the second rotating shaft 232 are disposed in the second receiving space 502. The first opening 1010 of the first housing portion 101 passes through the second receiving space 502 and the outer space of the first housing portion 101. The first pawl 221 and the first toothed structure 2113 engage with each other through the first opening 1010, and the second pawl 222 and the second toothed structure 2123 engage with each other through the first opening 1010. In this way, the first pawl 221, the second pawl 222, the first pawl shaft 231 and the second pawl shaft 232 are located in the second receiving space 502, and the circuit board assembly 40 is located in the first receiving space 501. The first opening 101 through which the first pawl 221 and the second pawl 222 pass passes through the second receiving space 502 and the outer space of the first shell part 101, and the first receiving space 501 is a completely sealed space, thereby effectively ensuring the safety and service life of the circuit board assembly 40 in the first receiving space 501, which helps to improve the service life of the watch.

[0037] Alternatively, see Figure 8 The watch also includes a sealing rubber ring 70, which includes a first portion 71 and a second portion 72 connected to each other. The first portion 71 is arranged along the extension direction of the baffle 13 to seal the first receiving space 501 and the second receiving space 502, respectively, and the second portion 72 is arranged around the receiving spaces. The second portion 72 includes a first sealing segment 721 and a second sealing segment 722. The two ends of the first sealing segment 721 are respectively connected to the two ends of the first portion 71 to seal the first receiving space 501, and the two ends of the second sealing segment 722 are respectively connected to the two ends of the first portion 71 to seal the second receiving space 502. Furthermore, the provision of the sealing rubber ring 70 can effectively ensure the sealing of the first receiving space 501 and the second receiving space 502, thereby effectively ensuring the safety and stability of the components arranged in the first receiving space 501 and the second receiving space 502, which helps to improve the service life of the watch.

[0038] It should be noted that the sealing rubber ring 70 can be set at the connection between the baffle 13 and the bottom cover 12. The setting of the sealing rubber ring 70 effectively ensures the sealing between the baffle 13 and the bottom cover 12, thereby ensuring the sealing of the first receiving space 501 and the second receiving space 502.

[0039] Please refer to Figures 2 to 5The watch also includes a decorative ring 60, which is stacked with the first ratchet ring 211 along the first direction (which can be understood as a direction perpendicular to the watch screen). One of the decorative ring 60 and the first ratchet ring 211 is provided with a first mounting groove; the other of the decorative ring 60 and the first ratchet ring 211 is provided with a first connecting protrusion. The first connecting protrusion extends into the first mounting groove to rotatably connect the decorative ring 60 and the first ratchet ring 211. Furthermore, the provision of the first mounting groove and the first connecting protrusion ensures the stability of the connection between the decorative ring 60 and the first ratchet ring 211 while also ensuring that the first ratchet ring 211 can rotate.

[0040] Alternatively, as Figure 6 As shown, a first connecting protrusion 61 is provided on the side of the decorative ring 60 facing the first ratchet ring 211, and the first ratchet ring 211 is correspondingly provided with a first mounting groove 2111; the first connecting protrusion 61 extends into the first mounting groove 2111, so that the decorative ring 60 is rotatably connected to the first ratchet ring 211, ensuring that the first ratchet ring 211 can rotate relative to the watch case 11, thereby providing users with a real mechanical segment sense and improving the user experience of the watch.

[0041] Alternatively, in some embodiments, a first mounting groove may be provided on the side of the decorative ring 60 facing the first ratchet ring 211, and the first ratchet ring 211 may be provided with a corresponding first connecting protrusion; the first connecting protrusion extends into the first mounting groove, so that the decorative ring 60 and the first ratchet ring 211 are rotatably connected. Such an arrangement can also ensure that the first ratchet ring 211 can rotate relative to the watch case 11.

[0042] Furthermore, if Figure 6 and Figure 7 As shown, the first ratchet ring 211 is provided with a first mounting groove 2111 and a first connecting side wall 241 and a second connecting side wall 242 for enclosing the first mounting groove 2111; the decorative ring 60 is provided with the first connecting protrusion 61 and the first limiting protrusion 62, the first limiting protrusion 62 is provided on one side of the first connecting protrusion 61, and the first limiting protrusion 62 and the first connecting protrusion 61 extend in the same direction to form the first limiting groove 240; when the decorative ring 60 is rotatably connected to the first ratchet ring 211, the first connecting side wall 241 extends into the first limiting groove 240, thereby limiting the radial movement of the first ratchet ring 211 relative to the decorative ring 60 perpendicular to the first direction, thereby avoiding the first ratchet ring 211 from being displaced in the radial direction perpendicular to the first direction.

[0043] It can be understood that in some embodiments, the decorative ring 60 may be provided with the first mounting groove and the first connecting side wall and the second connecting side wall for enclosing the first mounting groove; the first connecting protrusion and the first limiting protrusion are provided in the first ratchet ring 211, and the first limiting protrusion is provided on one side of the first connecting protrusion, and the first limiting protrusion and the first connecting protrusion extend in the same direction to form the first limiting groove 240; when the decorative ring 60 is rotatably connected to the first ratchet ring 211, the first connecting side wall extends into the first limiting groove, limiting the radial movement of the first ratchet ring 211 relative to the decorative ring 60 along a direction perpendicular to the first direction.

[0044] It should be noted that the decorative ring 60 can be sleeved on the outside of the watch case 11, with the inner side of the decorative ring 60 (the side facing the watch case 11) fixedly connected to the watch case 11, such as by bonding or snap-fitting, thereby making the decorative ring 60 immovable. Alternatively, in some embodiments, the decorative ring 60 is sleeved on the outside of the watch case 11 and is not fixedly connected to the watch case 11. The decorative ring 60 can rotate with the first ratchet ring 211, thereby providing a better user experience.

[0045] Optionally, the watch further includes a first sealing ring 261 disposed between the decorative ring 60 and the first ratchet ring 211, and a first sealing groove 2610 for accommodating the first sealing ring 261. It is understood that the provision of the first sealing ring 261 can prevent dust, moisture, and other substances from entering the gap between the decorative ring 60 and the first ratchet ring 211, thereby helping to improve the performance and service life of the first ratchet ring 211.

[0046] For details, please refer to Figure 6 In some embodiments, a first limiting protrusion 62 is further provided on the side of the decorative ring 60 facing the first ratchet ring 211. The first limiting protrusion 62 is disposed on one side of the first connecting protrusion 61 and extends in the same direction as the first connecting protrusion 61 to form a first limiting groove 240. The first ratchet ring 211 also includes a first connecting sidewall 241 and a second connecting sidewall 242 that enclose the first mounting groove 2111. When the decorative ring 60 and the first ratchet ring 211 are rotatably connected, the first connecting sidewall 241 extends into the first limiting groove 240, thereby limiting radial movement of the first ratchet ring 211 relative to the decorative ring 60 in a direction perpendicular to the first direction.

[0047] Please combine Figure 6 and Figure 7 The watch further includes a first sealing ring 261 and a first sealing groove 2610 for accommodating the first sealing ring 261. The configuration of the first sealing ring 261 and the first sealing groove 2610 satisfies at least one of the following:

[0048] (1) The first sealing ring 261 is disposed between the first connecting side wall 241 and the side wall of the first connecting protrusion 61, and the first sealing groove 2610 is disposed in at least one of the first connecting side wall 241 and the first connecting protrusion 61;

[0049] (2) The first sealing ring 261 is disposed between the second connecting side wall 242 and the side wall of the first connecting protrusion 61, and the first sealing groove 2610 is disposed in at least one of the second connecting side wall 242 and the first connecting protrusion 61;

[0050] (3) The first sealing ring 261 is disposed between the first connecting side wall 241 and the bottom of the first limiting groove 240 , and the first sealing groove 2610 is disposed in at least one of the first connecting side wall 241 and the first limiting groove 240 ;

[0051] (4) The first sealing ring 261 is disposed between the end surface of the second connecting side wall 242 and the decorative ring 60 , and the first sealing groove 2610 is disposed in at least one of the end surface of the second connecting side wall 242 and the decorative ring 60 .

[0052] It should be noted that the first sealing ring 261 can be a sealing ring made of a soft material, such as a rubber material or a silicone material. Furthermore, the first sealing ring 261 also has a certain buffering performance. In the embodiment of the present application, the setting of the first sealing ring 261 and the first sealing groove 2610 includes at least one of the above (1) to (4). Through the setting of the first sealing ring 261, a certain buffering performance can be provided for the connection between the first ratchet ring 211 and the decorative ring 60, and the sealing between the first ratchet ring 211 and the decorative ring 60 can be effectively guaranteed, preventing impurities such as water and dust from entering the gap between the decorative ring 60 and the first ratchet ring 211 and affecting the rotation of the first ratchet ring 211, effectively ensuring the smoothness of the rotation of the first ratchet ring 211, and also helping to improve the service life of the first ratchet ring 211.

[0053] Alternatively, please continue to refer to Figure 6 and Figure 7The watch also includes a first rolling member 251. A first guide groove 2511 is defined at the bottom of the first mounting groove 2111, and a second guide groove 2512 is defined on the end surface of the first connecting protrusion 61. The first guide groove 2511 and the second guide groove 2512 extend along the rotational direction of the first ratchet ring 211. When the decorative ring 60 is rotatably connected to the first ratchet ring 211, the first guide groove 2511 and the second guide groove 2512 are opposed to and communicate with each other to form a first guide channel 2510. The first rolling member 251 is rotatably disposed within the first guide channel 2510. As will be appreciated, during rotation of the first ratchet ring 211, the first rolling member 251 can roll within the first guide channel 2510 as the first ratchet ring 211 rotates, thereby ensuring that the first ratchet ring 211 can rotate in the first rotational direction and guiding the rotation of the first ratchet ring 211. Moreover, since the first guide channel 2510 is formed by the first guide groove 2511 provided with the bottom of the first mounting groove 2111 and the second guide groove 2512 provided on the first connecting protrusion 61, the first rolling member 251 is accommodated between the first guide groove 2511 and the second guide groove 2512. Such an arrangement can also prevent the first ratchet ring 211 from being displaced relative to the decorative ring 60 in a radial direction perpendicular to the first direction.

[0054] In an embodiment of the present application, the decorative ring 60 and the first ratchet ring 211 are rotationally connected through the first connecting protrusion 61 and the first mounting groove 2111, and can also achieve mutual limiting cooperation in the radial direction through the first guide groove 2511, the second guide groove 2512 and the first rolling element 251, thereby improving the overall rigidity of the watch when it falls.

[0055] It should be noted that the bottom of the first mounting groove 2111 may be provided with N (N is a positive integer) first guide grooves 2511, and the end surface of the first connecting protrusion 61 may be correspondingly provided with N second guide grooves 2512. The N first guide grooves 2511 and the N second guide grooves 2512 are provided in a one-to-one correspondence to form N first guide channels 2510, each of which is provided with a first rolling element 251. When N is greater than 1, the provision of multiple rolling elements 251 and multiple first guide channels 2510 helps to better guide the rotation of the first ratchet ring 211.

[0056] In addition, the diameters of the first guide groove 2511 and the second guide groove 2512 may be slightly larger than the diameter of the first rolling element 251 , thereby avoiding obstruction to the displacement of the first rolling element 251 and thus avoiding obstruction to the rotation of the first ratchet ring 211 .

[0057] In the embodiment of the present application, the first ratchet ring 211 and the second ratchet ring 212 are stacked along a first direction, and one of the first ratchet ring 211 and the second ratchet ring 212 is provided with a second mounting groove; the other of the first ratchet ring 211 and the second ratchet ring 212 is provided with a second connecting protrusion; the second connecting protrusion extends into the second mounting groove, thereby rotatably connecting the first ratchet ring 211 and the second ratchet ring 212. Furthermore, the provision of the second mounting groove and the second connecting protrusion ensures that the first ratchet ring 211 and the second ratchet ring 212 are rotatably connected, while also preventing displacement between the first ratchet ring 211 and the second ratchet ring 212 in a radial direction perpendicular to the first direction, thereby helping to improve the connection stability between the first ratchet ring 211 and the second ratchet ring 212.

[0058] For example, in some embodiments, a second connecting protrusion may be provided on one side of the second ratchet ring 212, a second mounting groove may be provided on the side of the first ratchet ring 211 facing the second ratchet ring 212, and the second connecting protrusion may extend into the second mounting groove.

[0059] Or, as Figure 6 and Figure 7 As shown, the first ratchet ring 211 is provided with a second connecting protrusion 2112 on the side facing the second ratchet ring 212, and the second ratchet ring 212 is correspondingly provided with a second mounting groove 2120; the second connecting protrusion 2112 extends into the second mounting groove 2120, thereby rotatably connecting the first ratchet ring 211 and the second ratchet ring 212. The second ratchet ring 212 also includes a first mounting sidewall 2121 and a second mounting sidewall 2122 for enclosing and forming the second mounting groove 2120. The watch also includes a second sealing ring 262 and a second sealing groove 2620 for accommodating the second sealing ring 262. The configuration of the second sealing ring 262 and the second sealing groove 2620 satisfies at least one of the following requirements:

[0060] (1) The second sealing ring 262 is disposed between the first mounting side wall 2121 and the side wall of the second connecting protrusion 2112, and the second sealing groove 2620 is disposed in at least one of the first mounting side wall 2121 and the second connecting protrusion 2112;

[0061] (2) The second sealing ring 262 is disposed between the second mounting side wall 2122 and the side wall of the second connecting protrusion 2112, and the second sealing groove 2620 is disposed in at least one of the second mounting side wall 2122 and the second connecting protrusion 2112;

[0062] (3) The second sealing ring 262 is disposed between the end surface of the second mounting side wall 2122 and the first ratchet ring 211 , and the second sealing groove 2620 is disposed in at least one of the end surface of the second mounting side wall 2122 and the first ratchet ring 211 .

[0063] Among them, the second sealing ring 262 can be a sealing ring of soft material, such as rubber material or silicone material. Furthermore, the second sealing ring 262 also has a certain buffering performance. In the embodiment of the present application, the setting of the second sealing ring 262 and the second sealing groove 2620 includes at least one of the above (1) to (3), and further, through the setting of the second sealing ring 262, it is possible to provide a certain buffering performance for the connection and rotation between the first ratchet ring 211 and the second ratchet ring 212, and the sealing of the first ratchet ring 211 and the second ratchet ring 212 can be achieved through the second sealing ring 262, so as to prevent impurities such as water and dust from entering the gap between the first ratchet ring 211 and the second ratchet ring 212 and affecting the rotation of the first ratchet ring 211 and the second ratchet ring 212, thereby helping to improve the service life of the first ratchet ring 211 and the second ratchet ring 212.

[0064] Optionally, a third sealing ring 263 is provided between the second ratchet ring 212 and the bearing portion 1021. A third sealing groove is provided on the side of the second ratchet ring 212 facing the bearing portion 1021 and / or on the side of the bearing portion 1021 facing the second ratchet ring 212. The third sealing ring 263 is received in the third sealing groove. Furthermore, the third sealing ring 263 provides a seal, preventing impurities such as water and dust from entering the gap between the second ratchet ring 212 and the bearing portion 1021 and affecting the rotation of the second ratchet ring 212, thereby improving the service life of the second ratchet ring 212.

[0065] It should be noted that the above-mentioned first sealing ring 261, second sealing ring 262 and third sealing ring 263 are elastic sealing rings. While providing dustproof and waterproof functions to the first ratchet ring 211 and the second ratchet ring 212, they can also achieve a rotational damping feeling, bringing a better experience to the user when the user rotates the first ratchet ring 211 and the second ratchet ring 212.

[0066] Furthermore, the provision of the first sealing ring 261 can accommodate axial tolerances between the first ratchet ring 211 and the decorative ring 60. The provision of the second sealing ring 262 can accommodate axial tolerances between the first ratchet ring 211 and the second ratchet ring 212. The provision of the third sealing ring 263 can accommodate axial tolerances between the second ratchet ring 212 and the watch case 11. Thus, the provision of the first sealing ring 261, the second sealing ring 262, and the third sealing ring 263 can reduce the dimensional accuracy requirements for the first ratchet ring 211 and the second ratchet ring 212, thereby preventing the first ratchet ring 211 and the second ratchet ring 212 from feeling loose in the axial and radial directions.

[0067] Alternatively, please continue to refer to Figure 6 and Figure 7The watch also includes a second rolling member 252, a first rolling groove 2521 is provided at the bottom of the second mounting groove 2120, and a second rolling groove 2522 is provided at the end face of the second connecting protrusion 2112; the first rolling groove 2521 and the second rolling groove 2522 extend along the rotation direction of the second ratchet ring 212; when the first ratchet ring 211 and the second ratchet ring 212 are rotatably connected, the first rolling groove 2521 and the second rolling groove 2522 are opposite to and connected to form a second guide channel 2520, and the second rolling member 252 is rotatably arranged in the second guide channel 2520. It is understandable that during the rotation of the first ratchet ring 211 and / or the second ratchet ring 212, the second rolling element 252 can roll within the second guide channel 2520 along with the rotation of the first ratchet ring 211 and / or the second ratchet ring 212, thereby ensuring that the first ratchet ring 211 can rotate in the first rotation direction and the second ratchet ring 212 can rotate in the second rotation direction, and guiding the rotation of the first ratchet ring 211 and the second ratchet ring 212. Furthermore, since the second guide channel 2510 is formed by the first rolling groove 2521 and the second rolling groove 2522, the second rolling element 252 is accommodated between the first rolling groove 2521 and the second rolling groove 2522. This arrangement can also prevent the first ratchet ring 211 and the second ratchet ring 212 from being displaced in a radial direction perpendicular to the first direction.

[0068] In the embodiment of the present application, the first ratchet ring 211 and the second ratchet ring 212 are movably connected through the second connecting protrusion 2112 and the second mounting groove 2120, and can also achieve mutual limiting cooperation in the radial direction through the first rolling groove 2521, the second rolling groove 2522 and the second rolling element 252, thereby improving the overall rigidity of the watch when it falls, and helping to improve the mechanical reliability of the watch.

[0069] It should be noted that the bottom of the second mounting groove 2120 may be provided with M (M is a positive integer) first rolling grooves 2521, and the end surface of the second connecting protrusion 2112 may be correspondingly provided with M second rolling grooves 2522. The M first rolling grooves 2521 and the M second rolling grooves 2522 are arranged in a one-to-one correspondence to form M second guide channels 2520, each of which is provided with a second rolling element 252. When M is greater than 1, the provision of multiple second rolling elements 252 and multiple second guide channels 2520 helps to better guide the rotation of the first ratchet ring 211 and the second ratchet ring 212.

[0070] In addition, the groove diameters of the first rolling groove 2521 and the second rolling groove 2522 can be slightly larger than the diameter of the second rolling element 252, so as to avoid obstructing the displacement of the second rolling element 252, and thus avoid obstructing the rotation of the first ratchet ring 211 and the second ratchet ring 212.

[0071] Please refer to Figure 9 The watch provided in the embodiment of the present application may further include a stopper 29. When the first ratchet ring 211 rotates in the first rotational direction, the stopper 29 and the first pawl 221 are sequentially arranged along the first rotational direction. The stopper 29 also serves to limit the first pawl 221, thereby preventing the first pawl 221 from deviating in the first rotational direction following the first ratchet ring 211.

[0072] Optionally, when the watch further includes a second ratchet ring 212, a second pawl 222, and a second rotating shaft 232, the stopper 29 is disposed between the first pawl 221 and the second pawl 222. In this way, the stopper 29 can limit the first pawl 221 and the second pawl 222, thereby preventing the first pawl 221 and the second pawl 222 from colliding with each other and helping the first pawl 221 and the second pawl 222 to return to their correct positions.

[0073] In the embodiment of the present application, the first ratchet ring 211 can only rotate in the first rotational direction. When a user applies a force to the first ratchet ring 211 to rotate in the second rotational direction, the first pawl 221 clamps the first ratchet ring 211, preventing it from rotating in the opposite direction. If the first pawl shaft 231 were to provide a reverse force, the first pawl shaft 231 would be easily damaged. However, the stopper 29 can provide a reverse force to prevent the first ratchet ring 221 from rotating in the second rotational direction, thereby preventing damage to the first pawl 221 and the first pawl shaft 231. Similarly, the second ratchet ring 212 can only rotate in the second rotational direction. When a user applies a force to the second ratchet ring 211 to rotate in the first rotational direction, the stopper 29 also prevents damage to the second pawl 222 and the second pawl shaft 232.

[0074] Optionally, in some embodiments, the watch further includes a first magnetic member 271 and a first Hall sensor 281. The first magnetic member 271 is fixed to the first pawl 221, and the first Hall sensor 281 is fixed to the housing assembly 10 or the circuit board assembly 40. For example, the first Hall sensor 281 is located on a side of the baffle 13 near the first pawl 221, and the first Hall sensor 281 is located within the first receiving space 50. The first Hall sensor 281 is electrically connected to the circuit board assembly 40. When the first ratchet ring 211 rotates in a first rotational direction, the first toothed structure 2113 pushes the first pawl 221 to swing back and forth. The first Hall sensor 281 responds to the rotation of the first ratchet ring 211 through the first magnetic member 271, causing the watch to perform a first operation, such as locking or lighting the screen, increasing or decreasing the volume, etc. The first operation is not specifically limited in this embodiment of the present application. Furthermore, the user can trigger the watch to perform the first operation by rotating the first ratchet ring 221, which makes user operation more convenient and further enhances the user experience.

[0075] Optionally, please refer to Figures 8 to 10 In some embodiments, the watch provided by the embodiments of the present application includes a first magnetic member 271 and a second magnetic member 272 that attract each other. The first magnetic member 271 is fixed to the first pawl 221. When the first ratchet ring 211 rotates in a first rotational direction, the second magnetic member 272 is disposed on a side of the first magnetic member 271 that is away from the first rotational direction. Thus, the magnetic force between the first magnetic member 271 and the second magnetic member 272 attracts the first pawl 221 to rotate away from the first rotational direction and reset. Exemplarily, the first magnetic member 271 is disposed on a first side surface of the first pawl 221, and the second magnetic member 272 is disposed on a second side surface of the first pawl 221. The first side surface and the second side surface are two opposite sides of the first pawl 221.

[0076] Optionally, when the watch further includes a second ratchet ring 212, a second pawl 222 and a second rotating shaft 232, the second magnetic member 272 is fixed to the second pawl 222. Figure 7 As shown, the first pawl 221 is provided with a first magnetic member 271, and the second pawl 222 is provided with a second magnetic member 272, and the first magnetic member 271 and the second magnetic member 272 are magnetically attracted to each other. It can be understood that since the first ratchet ring 211 rotates in the first rotation direction, it will drive the first pawl 221 to swing in the first rotation direction, and the second ratchet ring 212 rotates in the second rotation direction, it will drive the second pawl 222 to swing in the second rotation direction. The magnetic attraction between the first magnetic member 271 and the second magnetic member 272 will drive the first pawl 221 and the second pawl 222 to move in a direction close to each other, thereby achieving the reset of the first pawl 221 and the second pawl 222.

[0077] In the embodiment of the present application, the magnetic attraction between the first magnetic member 271 and the second magnetic member 272 causes the first pawl 221 and the second pawl 222 to always maintain a directional rotation trend. When the user rotates the first ratchet ring 211 by a non-integer ratchet angle, the C-shaped surface of the first hook 2211 on the first pawl 221 (the surface in contact with the first tooth structure 2113) and the first tooth structure 2113 are always in close contact. When the user lets go, under the action of magnetism, the first pawl 221 will rotate and reset in the second rotation direction, and push the first tooth structure 2113 and the first ratchet ring 211 to rotate a certain angle through the C-shaped surface of the first hook 2211, so that when the user does not apply force to the first ratchet ring 211, the first ratchet ring 211 always maintains an integer multiple ratchet rotation state. Accordingly, when the user rotates the second ratchet ring 212 by a non-integer ratchet angle, the C-shaped surface of the first hook 2221 on the second pawl 222 (the surface in contact with the second toothed structure 2123) and the second toothed structure 2123 are always in close contact. When the user releases the grip, the second pawl 222 rotates back to the first rotation direction under the action of magnetism, and pushes the second toothed structure 2123 and the second ratchet ring 212 to rotate a certain angle through the C-shaped surface of the second hook 2221. As a result, when the user does not apply force to the second ratchet ring 212, the second ratchet ring 212 always maintains an integer multiple ratchet rotation state. This arrangement makes the rotation of the first ratchet ring 211 and the second ratchet ring 212 more precise, and can provide the user with a better mechanical experience.

[0078] Optionally, the watch may further include a first Hall sensor 281 and a second Hall sensor 282. In the embodiment of the present application, the housing assembly 10 includes a baffle 13, which divides the receiving space 50 into a first receiving space 501 and a second receiving space 502 that are independent of each other; the circuit board assembly 40 is received in the first receiving space 501, and the first pawl 221, the first rotating shaft 231, the second pawl 222, and the second rotating shaft 232 are disposed in the second receiving space 502. The first Hall sensor 281 and the second Hall sensor 282 are disposed in the first receiving space 501, and are electrically connected to the circuit board assembly 40, respectively; the first Hall sensor 281 is disposed on one side of the baffle 13 close to the first magnetic member 271, and the second Hall sensor 282 is disposed on the other side of the baffle 13 close to the second magnetic member 272. Illustratively, the second Hall sensor 282 , the second magnetic member 272 , the first magnetic member 271 , and the first Hall sensor 281 are sequentially arranged along the first rotation direction of the first ratchet ring 211 .

[0079] like Figure 8As shown, the baffle 13 includes a first side wall 131, a second side wall 132, and a third side wall 133 connected in sequence. The end of the first side wall 131 away from the second side wall 132 is connected to the watch case 11, and the end of the third side wall 133 away from the second side wall 132 is connected to the watch case 11. The first side wall 131 and the third side wall 133 are arranged opposite each other. The first side wall 131 is adjacent to the first pawl 221, and the third side wall 133 is adjacent to the second pawl 222. A first Hall sensor 281 is provided on the side of the first side wall 131 facing the first receiving space 501, and a second Hall sensor 282 is provided on the side of the third side wall 133 facing the first receiving space 501. The first Hall sensor 281 and the second Hall sensor 282 are electrically connected to the circuit board assembly 40. The first pawl 221 is provided with a first magnet 271, and the second pawl 222 is provided with a second magnet 272. When the user rotates the first ratchet ring 211, the first ratchet ring 211 drives the first pawl 221 to swing, thereby causing the first magnet 271 on the first pawl 221 to displace. The displacement of the first magnet 271 triggers the first Hall sensor 281 to generate a first Hall effect, which can trigger the watch to perform a first operation. Correspondingly, when the user rotates the second ratchet ring 212, the second ratchet ring 212 drives the second pawl 222 to swing, thereby causing the second magnet 272 on the second pawl 222 to displace. The displacement of the second magnet 272 triggers the second Hall sensor 282 to generate a second Hall effect, which can trigger the watch to perform a second operation.

[0080] For example, when the user rotates the first ratchet ring 211 and triggers the first Hall sensor, the volume increase function of the watch can be realized; when the user rotates the second ratchet ring 212 and triggers the second Hall sensor, the volume reduction function of the watch can be realized.

[0081] For another example, in the application interface of the watch, when the user rotates the first ratchet ring 211 to trigger the first Hall sensor, or rotates the second ratchet ring 212 to trigger the second Hall sensor, the function of scrolling and positioning the application can be achieved.

[0082] For another example, in the alarm customization interface, when the user rotates the first ratchet ring 211 to trigger the first Hall sensor, or rotates the second ratchet ring 212 to trigger the second Hall sensor, the alarm time adjustment function can be realized. In the heart rate and sleep cancellation viewing interface, when the user rotates the first ratchet ring 211 to trigger the first Hall sensor, or rotates the second ratchet ring 212 to trigger the second Hall sensor, the specific numerical setting function of the positioning heart rate and sleep curve graph can be realized. In the map application interface, when the user rotates the first ratchet ring 211 to trigger the first Hall sensor, or rotates the second ratchet ring 212 to trigger the second Hall sensor, the map zoom in or out function can be realized. In the reading application interface such as e-books or the application interface such as video playback, when the user rotates the first ratchet ring 211 to trigger the first Hall sensor, or rotates the second ratchet ring 212 to trigger the second Hall sensor, the progress bar sliding function can be realized.

[0083] For example, by rotating the first ratchet ring 211 to trigger the first Hall effect sensor, or rotating the second ratchet ring 212 to trigger the second Hall effect sensor, the watch can be triggered to enter the payment interface or other specific interface. In addition, the user can also customize the number of rotations of the first ratchet ring 211 and / or the number of rotations of the second ratchet ring 212 to achieve the lock and unlock functions of the watch.

[0084] It should be noted that by rotating the first ratchet ring 211 to trigger the first Hall effect sensor, or by rotating the second ratchet ring 212 to trigger the second Hall effect sensor, the user can also trigger other functions of the watch, which are not listed in detail here. In the embodiment of the present application, the user can trigger related functions of the watch by rotating the first ratchet ring 211 and / or the second ratchet ring 212, which can avoid the problem of inaccurate touch screen operation caused by the small screen of the watch, and further enhance the user experience of the watch.

[0085] In the embodiment of the present application, the first Hall sensor 281 is disposed on the side of the first side wall 131 facing the first receiving space 501, and the second Hall sensor 282 is disposed on the side of the third side wall 133 facing the first receiving space 501. It is understood that the first receiving space 501 is a sealed space, and the first Hall sensor 281 and the second Hall sensor 282 are located within the first receiving space 501. This prevents the first and second Hall sensors 281 and 282 from being infiltrated by water or dust and thus affecting their performance, thereby helping to ensure the performance of the relevant functions of the watch.

[0086] Optionally, the diameters of the first ratchet ring 211 and the second ratchet ring 212 are both larger than the diameter of the decorative ring 60. It is understandable that the user needs to rotate the first ratchet ring 211 and the second ratchet ring 212 to experience the mechanical feel and realize related functions of the watch. The diameters of the first ratchet ring 211 and the second ratchet ring 212 are larger than the diameter of the decorative ring 60, which makes it more convenient for the user to hold the first ratchet ring 211 or the second ratchet ring 212.

[0087] In addition, teeth 201 may be provided on the outer walls of the first ratchet ring 211 and the second ratchet ring 212. The provision of the teeth 201 can increase the friction between the user's fingers and the first ratchet ring 211 or the second ratchet ring 212 when the user holds the first ratchet ring 211 or the second ratchet ring 212, thereby making it more convenient for the user to hold the first ratchet ring 211 or the second ratchet ring 212.

[0088] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
