Summary of the Invention

[0006] To solve the problem that is not helpful for the function expansion of the smartwatch, embodiments of this application provide a watch band and a watch. The technical solutions are as follows.

[0007] According to the first aspect, a watch band is provided and can be used with a watch. The watch band includes a first watch fastener, a second watch fastener, a first band body, and a second band body. The first watch fastener is provided with a receiving space, which is used to accommodate an electronic device. This is equivalent to providing an attachment space for the electronic device. One end of the first band body is connected to the first watch fastener and is configured to be electrically connected to the electronic device. The other end of the first band body is configured to be connected to the watch dial of the watch and can be electrically connected. Therefore, the electronic device is electrically connected to the watch dial via the first band body. Since various electronic devices are configured in the receiving space to expand the functions of the watch, the functions of the watch are improved. One end of the second band body is connected to the second watch fastener, and the other end of the second watch band body is configured to be connected to the watch dial. Since the second watch fastener is detachably connected to the first watch fastener, the watch band can be put on.

[0008] The watch band provided in the present embodiment of the present application has at least the following effects.

[0009] The watch band is used with a watch. Since the first watch fastener is provided with a receiving space, various electronic devices can be configured in the receiving space to expand the functions of the watch, so the functions of the watch are improved.

[0010] In the exemplary embodiment, the first watch fastener includes a first housing and a first cover. The first housing is an open-housing mechanical component. A boss is arranged on the inner bottom surface of the first housing. The top of the boss faces the opening of the first housing. A groove is provided in a portion of the boss away from the inner bottom surface of the first housing. That is, the groove is located at the top of the boss. The first cover is located at the opening of the first housing. The first cover is connected to the boss and covers the groove opening of the groove to form a receiving space between the first cover and the groove. That is, the receiving space is formed by covering the groove opening of the groove with the first cover. The receiving space is located between the first cover and the first housing.

[0011] In one embodiment, a seal groove is provided around the groove. The first watch fastener further includes a seal component. The seal component is located within the seal groove and is clamped between the first cover and the boss. In this design, the gap between the first cover and the boss is sealed through the seal component, thereby avoiding the impact on the electronic devices within the accommodation space caused by dust, liquid, etc. that enter the accommodation space.

[0012] In an exemplary embodiment, a lock slot is provided on the outer wall of the second watch fastener. The first watch fastener further includes a locking fastener. The first portion of the locking fastener is inserted into the first housing and is located on one side of the boss. The second portion of the locking fastener is located outside the first housing and is inserted into the lock slot. The locking fastener is movable relative to the first housing. In the process of moving the second portion of the locking fastener within the lock slot, the locking fastener and the lock slot can be locked or unlocked. That is, the locking fastener is disposed on the first watch fastener, and the lock slot is provided on the second watch fastener. The detachable connection between the first fastener and the second watch fastener is implemented through the engagement between the locking fastener and the lock slot.

[0013] In an exemplary embodiment, the locking fastener includes a first slide block and a first locking arm. A first portion of the first slide block is located within the first housing and is movable relative to the first housing. A second portion of the first slide block is located outside the first housing and can drive the entire first slide block to move together. A first portion of the first locking arm is connected to the first portion of the first slide block and is located on the side of the first slide block that is away from the inner bottom surface of the first housing. A second portion of the first locking arm is located outside the first housing. Since the first portion of the first locking arm is connected to the first slide block, the first locking arm can move together by driving the first slide block. A first notch is provided in the side wall of the second portion of the first locking arm, and the first notch is configured to fit the first protrusion. The first protrusion is located on the inner side wall of the lock slot and at the slot opening of the lock slot. The first protrusion faces the first notch. When the first slide block drives the second portion of the first locking arm away from the center of the second watch fastener and the first protrusion is located in the first notch, the locking fastener and the lock slot are locked to each other. When the first slide block drives the second portion of the first locking arm towards the center of the second watch fastener and the first protrusion is located outside the first notch, the mutual locking between the locking fastener and the lock slot is released.

[0014] In an exemplary embodiment, a first inclined surface is provided on the side of the first protrusion closer to the slot opening of the lock slot. In the direction towards the center of the second watch fastener, the first inclined surface is inclined from the slot opening of the lock slot towards the slot bottom. In this design, in the process of inserting the locking fastener into the lock slot, the top of the locking fastener abuts against the first inclined surface and moves along the first inclined surface to avoid the first protrusion. In this way, the locking fastener is gradually inserted into the lock slot, and the process of inserting the locking fastener into the lock slot becomes smoother.

[0015] In an exemplary embodiment, a second inclined surface is further provided on the inner wall of the lock slot. The second inclined surface faces the first inclined surface. In the direction towards the center of the second timepiece fastener, the second inclined surface is inclined from the bottom of the lock slot towards the slot opening. In this design, in the process of pulling out the lock fastener from the lock slot, since the lock fastener moves away from the center of the second timepiece fastener, the top of the lock fastener abuts against the second inclined surface. Since the lock fastener is pushed out from the lock slot under the action of the second inclined surface, the process of pulling out the lock fastener from the lock slot becomes smoother.

[0016] In an exemplary embodiment, the first timepiece fastener further includes a first elastic component. The first elastic component is located within the first housing and is compressed between the second portion of the lock fastener and the boss. The elastic direction of the first elastic component is the same as the moving direction of the lock fastener. That is, the first elastic component can always apply a force to move the lock fastener away from the center of the second timepiece fastener. In this design, when the lock fastener is in the initial state, under the action of the first elastic component, the lock fastener is located at a position away from the center of the second timepiece fastener. In the process of inserting the lock fastener into the lock slot, the lock fastener moves towards the center of the second timepiece fastener under the action of the first inclined surface, compresses the first elastic component, and avoids the first protrusion. After the first protrusion is avoided, the elastic potential energy of the first elastic component is released, and the lock fastener is pushed back away from the center of the second timepiece fastener. In this case, since the first protrusion is inserted into the first notch, the lock fastener and the lock slot are locked. In the process of pulling out the lock fastener from the lock slot, the lock fastener moves towards the center of the second timepiece fastener and compresses the first elastic component. The lock fastener is pushed out from the lock slot under the action of the second inclined surface, and the lock between the lock fastener and the lock slot is released. After the lock fastener is pulled out from the lock slot, the elastic potential energy of the first elastic component is released, and the lock fastener is moved away from the center of the second timepiece fastener.

[0017] In an exemplary embodiment, the locking fastener includes a drive block, a second slide block, and a second locking arm. A first portion of the drive block is located within the first housing and is movable relative to the first housing. A second portion of the drive block is located outside the first housing and can drive the entire drive block to move together. The second slide block is movably inserted into the first housing and is movable relative to the first housing. The second slide block is in sliding contact with the drive block, and there is an inner angle between the moving direction of the second slide block and the moving direction of the drive block. Therefore, when the drive block is moved, the drive block also pushes the second slide block to move together. A first portion of the second locking arm is located in the first housing and is connected to the second slide block. A second portion of the second locking arm is located outside the first housing. Since the first portion of the second locking arm is connected to the second slide block, the second locking arm can move together by driving the second slide block. A second notch is provided in the side wall of the second portion of the second locking arm, and the second notch is configured to fit the second protrusion. The second protrusion is located on the inner wall of the lock slot and at the slot opening of the lock slot. The second protrusion faces the second notch. When the drive block drives the second slide block to move the second portion of the second locking arm towards the center of the second clock fastener and the second protrusion is positioned in the second notch, the locking fastener and the lock slot are locked to each other. When the second slide block drives the second portion of the second locking arm away from the center of the second clock fastener and the second protrusion is located outside the second notch, the mutual locking between the locking fastener and the lock slot is released.

[0018] In an exemplary embodiment, a third inclined surface is provided on a side of the second protrusion closer to the slot opening of the lock slot. In a direction away from the center of the second watch fastener, the third inclined surface is inclined from the slot opening of the lock slot toward the slot bottom. In this design, during the process of inserting the lock fastener into the lock slot, the top of the lock fastener abuts against the third inclined surface and moves along the third inclined surface to avoid the second protrusion. In this way, the lock fastener is gradually inserted into the lock slot, and the process of inserting the lock fastener into the lock slot becomes smoother.

[0019] In an exemplary embodiment, a fourth inclined surface is further provided on the inner wall of the lock slot. The fourth inclined surface faces the third inclined surface. In a direction away from the center of the second watch fastener, the fourth inclined surface is inclined from the slot bottom of the lock slot toward the slot opening. In this design, during the process of pulling out the lock fastener from the lock slot, since the lock fastener moves away from the center of the second watch fastener, the top of the lock fastener abuts against the fourth inclined surface. Since the lock fastener is pushed out of the lock slot under the action of the fourth inclined surface, the process of pulling out the lock fastener from the lock slot becomes smoother.

[0020] In an exemplary embodiment, the first watch fastener further includes a second elastic component. The second elastic component is located in the first housing and is compressed between the second part of the locking fastener and the inner wall of the first housing. The elastic direction of the second elastic component is the same as the moving direction of the locking fastener. That is, the second elastic component can always apply a force to move the locking fastener towards the center of the second watch fastener. In the process of inserting the locking fastener into the lock slot, the locking fastener is affected by the third inclined surface and moves away from the center of the second housing, compressing the second elastic component and avoiding the second protrusion. After avoiding the second protrusion, the elastic potential energy of the second elastic component is released, moving the locking fastener towards the center of the second watch fastener. In this case, since the second protrusion is inserted into the second notch, the locking fastener and the lock slot are locked. In the process of pulling the locking fastener out of the lock slot, the locking fastener moves away from the center of the second watch fastener and compresses the second elastic component. Under the action of the fourth inclined surface, the locking fastener is pushed out of the lock slot, releasing the lock between the locking fastener and the lock slot. After the locking fastener is pulled out of the lock slot, the elastic potential energy of the second elastic component is released, and the locking fastener is pushed back towards the center of the second watch fastener.

[0021] In an exemplary embodiment, a first magnetic component is arranged on the first watch fastener. A second magnetic component is arranged on the second watch fastener, and the second magnetic component and the first magnetic component are attracted to each other. In this design, when the first watch fastener is fixed to the second watch fastener, the first magnetic component and the second magnetic component are attracted to each other. Under the influence of this magnetic force, the first watch fastener and the second watch fastener automatically move closer to each other and are locked to each other by the fitting between the locking fastener and the lock slot.

[0022] According to a second aspect, a clock is provided. The clock includes a clock face, a clock band, and an electronic device. The clock band is the clock band described above. One end of the first band body is connected to the first clock fastener. One end of the first band body on the side away from the first clock fastener is connected to the clock face. One end of the second band body is connected to the second clock fastener. One end of the second band body on the side away from the second clock fastener is connected to the clock face. The electronic device is located in the accommodation space within the first clock fastener. The electronic device is electrically connected to the clock face via the first band body.

[0023] The clock provided in this embodiment of the present application has at least the following effects.

[0024] Since various electronic devices can be accommodated in the first clock fastener of the clock band, the clock can have a plurality of different functions based on different electronic devices, the functions of the clock are extended, and the functionality of the clock is improved.

Mode for Carrying Out the Invention

[0027] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application and are not intended to limit the present application.

[0028] A smartwatch is an electronic clock. In addition to the timekeeping function of a conventional clock, a smartwatch has a plurality of other functions such as communication, navigation, and body monitoring.

[0029] In related technologies, a smartwatch mainly includes a watch dial and a watch band. An electronic device is arranged on the watch dial to implement various functions of the smartwatch. Since the watch band is connected to the watch dial, the smartwatch can be wound around the user's wrist. Currently, there are mainly two forms of watch bands. The main body of the first watch band is a metal hinge. One end of the metal hinge is locked or unlocked by using a butterfly fastener. The main body of the second watch band is a nylon band. One end of the nylon band is locked or unlocked by using a hook-and-loop fastener.

[0030] However, the functions of the above two watch bands are very simple, and only the function of winding the smartwatch around the user's wrist is provided. This is not helpful for expanding the functions of the smartwatch.

[0031] To solve the above technical problems, embodiments of the present disclosure provide a watch band. FIG. 1 is a schematic diagram of the structure of the watch band. Please refer to FIG. 1. The watch band includes a first watch fastener 1, a second watch fastener 2, a first band body 3, and a second band body 4.

[0032] FIG. 2 is a cross-sectional view of FIG. 1 in the direction A-A. Referring to FIG. 2, a receiving space A is provided in the first watch fastener 1, and the receiving space A is used to accommodate an electronic device 300. The second watch fastener 2 is detachably connected to the first watch fastener 1. One end of the first band body 3 is connected to the first watch fastener 1 and is configured to be electrically connected to the electronic device 300. One end of the second band body 4 is connected to the second watch fastener 2.

[0033] The watch band is used for a watch. Since the receiving space A is provided in the first watch fastener 1, various electronic devices 300 can be configured in the receiving space A to expand the functions of the watch, so the functionality of the watch is improved.

[0034] From the above, the watch band provided in the embodiment of the present application has an accommodation space A provided in the first watch fastener 1, and can accommodate an electronic device 300 having various functions in the accommodation space A, which is useful for expanding the functions of a smart watch. The configuration of the accommodation space A will be described below.

[0035] FIG. 3 is a schematic view showing the structure of the first watch fastener 1. FIG. 4 is an exploded view of the first watch fastener 1. Referring to FIGS. 3 and 4, in this embodiment, the first watch fastener 1 includes a first housing 11 and a first cover 12.

[0036] The first housing 11 is an open housing-like mechanical part. A boss 111 is disposed on the inner bottom surface of the first housing 11. The top of the boss 111 faces the opening of the first housing 11. A groove 112 is provided in a portion of the boss 111 that is away from the inner bottom surface of the first housing 11. That is, the groove 112 is located at the top of the boss 111. The first cover 12 is located at the opening of the first housing 11. The first cover 12 is connected to the boss 111 and covers the groove opening of the groove 112 to form an accommodation space A between the first cover 12 and the groove 112.

[0037] In the above embodiment, the accommodation space A is formed by covering the groove opening of the groove 112 with the first cover 12. The accommodation space A is located between the first cover 12 and the first housing 11. When the electronic device 300 is disposed in the accommodation space A, the electronic device 300 is first disposed in the groove 112 at the top of the boss 111, so that the electronic device 300 is electrically connected to the first band body 3. Then, since the first cover 12 covers the groove opening of the groove 112 and the first cover 12 is connected to the boss 111, the electronic device 300 is accommodated in the accommodation space A.

[0038] Optionally, to ensure accurate assembly of the first cover 12 and the boss 111, a plurality of positioning pins 114 are arranged on the part of the boss 111 that is farther from the inner bottom surface of the first housing 11. The plurality of positioning pins 114 are arranged at intervals along the outer edge of the boss 111. A plurality of positioning openings 121 are provided on the outer edge of the first cover 12. The positioning openings 121 have a one-to-one correspondence with the positioning pins 114. During assembly, the first cover 12 first covers the opening of the first housing 11 to ensure that all the positioning pins 114 are inserted into the corresponding positioning openings 121. In this case, the first cover 12 will not shake unnecessarily with the positioning of the positioning pins 114. Then, the first cover 12 is connected to the boss 111 via components such as screws.

[0039] In addition, the positioning pins 114 can further perform positioning with the second clock fastener 2. FIG. 5 is a rear view of the second clock fastener. The rear side of the second clock fastener is the side facing the first clock fastener 1. A plurality of positioning holes 23 are provided on the outer wall of the second clock fastener 2. The plurality of positioning holes 23 are arranged at intervals along the outer edge of the second clock fastener 2 and have a one-to-one correspondence with the positioning pins 114. When the first housing 11 and the first cover 12 are assembled together, one end of the positioning pin 114 on the side farther from the boss 111 penetrates the first cover 12. After the first clock fastener 1 and the second clock fastener 2 are connected together, the positioning pins 114 can be inserted into the corresponding positioning holes 23 to avoid unnecessary shaking between the first clock fastener 1 and the second clock fastener 2.

[0040] To ensure the lifespan of the electronic device 300, it is necessary to perform dustproof and waterproof processing on the electronic device 300. Please still refer to FIG. 4. In this embodiment, a seal groove 113 is provided around the groove 112. The seal groove 113 is located on the part of the boss 111 that is farther from the inner bottom surface of the first housing 11, that is, at the top of the boss 111. The first clock fastener 1 further includes a seal component 13. The seal component 13 is located in the seal groove 113 and is clamped between the first cover 12 and the boss 111.

[0041] In this design, the gap between the first cover 12 and the boss 111 is sealed via the sealing component 13, so as to avoid the impact on the electronic device 300 in the accommodation space A caused by dust, liquid, etc. that enter the accommodation space A.

[0042] For example, the sealing component 13 is a rubber component. When the first cover 12 is connected to the boss 111, the first cover 12 also covers the sealing groove 113. Since the sealing component 13 has a predetermined elasticity, the sealing component 13 is compressed between the sealing groove 113 and the first cover 12 to reliably seal the accommodation space A.

[0043] Optionally, since it is necessary to electrically connect the electronic device 300 in the accommodation space A to the first band body 3, it is necessary to extend the first band body 3 into the accommodation space A. Therefore, there are notches at each of the end of the groove 112 and the end of the sealing groove 113, and the notch of the groove 112 faces the notch of the sealing groove 113. A flexible printed circuit (FPC) 31 is disposed on the first band body 3. One end of the flexible printed circuit 31 sequentially penetrates through the notch of the sealing groove 113 and the notch of the groove 112 and is inserted into the accommodation space A, and is electrically connected to the electronic device 300. The other end of the flexible printed circuit 31 is embedded in the first band body 3 and extends along the length direction of the first band body 3 and is electrically connected to the dial 100. In order to seal the notch of the groove 112 and the notch of the sealing groove 113, the portions of the sealing component 13 corresponding to the two notches are fitted into the two notches. In this way, the two notches can be filled to obtain a sealing effect.

[0044] From the above, it can be seen that the first watch fastener 1 is detachably connected to the second watch fastener 2. Since the accommodation space A is provided in the first watch fastener 1 and occupies a part of the space of the first watch fastener 1, the conventional connection method is not applicable in this embodiment of the present application. In order to solve the above technical problems, in the embodiment of the present application, a detachable connection method between the first watch fastener 1 and the second watch fastener 2 is provided. This will be described below.

[0045] FIG. 6 is a schematic diagram of the disassembled state and the assembled state of the first watch fastener 1 and the second watch fastener 2. Referring to FIG. 6, in this embodiment, the first watch fastener 1 further includes a lock fastener 14. The lock fastener 14 is connected to the first housing 11 and is movable with respect to the first housing 11, and the lock fastener 14 is located on one side of the boss 111. A lock slot 21 is provided on the outer wall of the second watch fastener 2. Since the portion of the lock fastener 14 away from the first housing 11 is inserted into the lock slot 21, the lock fastener 14 and the lock slot 21 are locked or unlocked.

[0046] In the above implementation, the first housing 11 provides an assembly basis for the first part of the lock fastener 14. Therefore, the first part of the lock fastener 14 is movable with respect to the first housing 11. Specifically, the second part of the lock fastener 14 is movable with respect to the first housing 11 together with the first part. In addition, since the lock fastener 14 is located on one side of the boss 111, the lock fastener 14 does not interfere with the boss 111. That is, it does not affect the accommodation space A located at the top of the boss 111. When the lock fastener 14 is inserted into the lock slot 21, by moving the second part of the lock fastener 14, the lock fastener 14 and the lock slot 21 are locked or unlocked with each other. That is, the lock fastener 14 is arranged on the first watch fastener 1, and the lock slot 21 is provided on the second watch fastener 2. Through the fitting of the lock fastener 14 and the lock slot 21, the detachable connection between the first watch fastener and the second watch fastener 2 is implemented.

[0047] In this embodiment, two fitting methods between the lock fastener 14 and the lock slot 21 are provided. The following separately describes the two fitting methods.

[0048] FIG. 6 mentioned above is the first fitting method between the lock fastener 14 and the lock slot 21. FIG. 7 is a schematic diagram of the locked state of the lock fastener 14 and the lock slot 21 in this fitting method. FIG. 8 is a schematic diagram of the unlocked state of the lock fastener 14 and the lock slot 21 in this fitting method.

[0049] Referring to FIGS. 7 and 8, in this embodiment, the second portion of the lock fastener 14 is located between the edge portion and the central portion of the second watch fastener 2. When the second portion of the lock fastener 14 is located at the first position of the lock slot 21, the second portion of the lock fastener 14 is near the edge of the second watch fastener 2, and the second portion of the lock fastener 14 and the lock slot 21 are locked to each other. When the second portion of the lock fastener 14 is located at the second position of the lock slot 21, the second portion of the lock fastener 14 is near the central portion of the second watch fastener 2, and the mutual locking between the second portion of the lock fastener 14 and the lock slot 21 is released.

[0050] Specifically, in this fitting method between the lock fastener 14 and the lock slot 21, when the user needs to operate the lock fastener 14 to lock the lock fastener 14 and the lock slot 21, the lock fastener 14 moves toward the edge of the second watch fastener 2, or when it is necessary to release the lock between the lock fastener 14 and the lock slot 21, the lock fastener 14 moves toward the central portion of the second watch fastener 2. In this way, the lock fastener 14 and the lock slot 21 are locked or unlocked.

[0051] For example, in this embodiment, the second watch fastener 2 is circular. In this case, the edge portion of the second watch fastener 2 is a portion close to the edge of the circle, and the central portion of the second watch fastener 2 is a portion close to the center of the circle. In another embodiment, the second watch fastener 2 is square. In this case, the edge portion of the second watch fastener 2 is a portion close to the edge of the square, and the central portion of the second watch fastener 2 is a portion close to the intersection of the diagonals of the square. It can be easily understood that the shape of the second watch fastener 2 is only used as an example, and the shape of the second watch fastener 2 is not limited in this application.

[0052] In addition, in the process of fitting the first watch fastener 1 and the second watch fastener 2 in the horizontal direction (the plane direction in which the first watch fastener 1 is fastened to the second watch fastener 2), the edge portion of the second watch fastener 2 corresponds to the edge portion of the first watch fastener 1, that is, the position away from the boss 111. The central portion of the second watch fastener 2 corresponds to the central portion of the first watch fastener 1, that is, the position close to the boss 111. That is, when the second portion of the lock fastener 14 is located at the first position of the lock slot 21, correspondingly, the first portion of the lock fastener 14 is located at the first position of the first housing 11. When the second portion of the lock fastener 14 is located at the second position of the lock slot 21, correspondingly, the second portion of the lock fastener 14 is located at the second position of the first housing 11. In addition, in the process of moving the second portion of the lock fastener 14 between the first position and the second position, the first portion of the lock fastener 14 always moves between the edge of the first housing 11 and the boss 111. In this case, the lock fastener 14 does not interfere with the boss 111. That is, it does not affect the accommodation space A located at the top of the boss 111.

[0053] FIG. 9 is a schematic view of the assembly of the lock fastener 14. The solid arrows in FIG. 9 indicate the moving directions of the lock fastener 14. Referring to FIG. 9, in this embodiment, the lock fastener 14 includes a first slide block 141 and a first lock arm 142. A first portion of the first slide block 141 is located in the first housing 11, a second portion of the first slide block 141 is located outside the first housing 11, and the first slide block 141 is movable relative to the first housing 11. A first portion of the first lock arm 142 is connected to the first portion of the first slide block 141 and is located on the side of the first slide block 141 away from the inner bottom surface of the first housing 11. A second portion of the first lock arm 142 is located outside the first housing 11, and a first notch 143 is provided in the side wall of the second portion of the first lock arm 142.

[0054] Since the second portion of the first slide block 141 is located outside the first housing 11, the user can drive and move the first portion of the first slide block 141 located in the first housing 11 by moving the second portion of the first slide block 141. In addition, since the first end of the first lock arm 142 is connected to the first portion of the first slide block 141, the first lock arm 142 also moves together during the process of moving the first slide block 141.

[0055] Referring to FIGS. 7 and 8, a first protrusion 211 is provided on the inner wall of the lock slot 21. The first protrusion 211 is located at the slot opening of the lock slot 21, and the first protrusion 211 faces the first notch 143.

[0056] When the first slide block 141 drives the second part of the first locking arm 142 to move away from the center of the second clock fastener 2 and the first protrusion 211 is positioned in the first notch 143, the locking fastener 14 and the locking slot 21 are locked with each other. When the first slide block 141 drives the second part of the first locking arm 142 to move towards the center of the second clock fastener 2 and the first protrusion 211 is positioned outside the first notch 143, the mutual locking between the locking fastener 14 and the locking slot 21 is released.

[0057] Referring to FIGS. 7 and 8, it can be seen that when the first protrusion 211 is inserted into the first notch 143, the locking fastener 14 and the locking slot 21 are locked. This means that the locking fastener 14 cannot be directly pulled out from the locking slot 21 in the direction from the slot bottom of the locking slot 21 to the slot opening. When the first protrusion 211 is positioned outside the first notch 143, the locking between the locking fastener 14 and the locking slot 21 is released. This means that the locking fastener 14 can be directly pulled out from the locking slot 21 in the direction from the slot bottom of the locking slot 21 to the slot opening.

[0058] Still referring to FIGS. 7 and 8, in this embodiment, in order to make the process of inserting the locking fastener 14 into the locking slot 21 smoother, a first inclined surface 212 is provided on the side of the first protrusion 211 closer to the slot opening of the locking slot 21. In the direction towards the center of the second clock fastener 2, the first inclined surface 212 inclines from the slot opening of the locking slot 21 towards the slot bottom. In this design, during the process of inserting the locking fastener 14 into the locking slot 21, the top of the locking fastener 14 abuts against the first inclined surface 212 and moves from the first position to the second position along the first inclined surface 212 to avoid the first protrusion 211. In this way, the locking fastener 14 is gradually inserted into the locking slot 21, and the process of inserting the locking fastener 14 into the locking slot 21 becomes smoother.

[0059] Correspondingly, in order to make the process of pulling out the lock fastener 14 from the lock slot 21 smoother, a second inclined surface 213 is further provided on the inner wall of the lock slot 21. The second inclined surface 213 faces the first inclined surface 212. In the direction towards the center of the second clock fastener 2, the second inclined surface 213 is inclined from the slot bottom of the lock slot 21 towards the slot opening. In this design, in the process of pulling out the lock fastener 14 from the lock slot 21, since the lock fastener 14 moves from the first position to the second position, the top of the lock fastener 14 abuts against the second inclined surface 213. Due to the action of the second inclined surface 213, the lock fastener 14 is pushed out from the lock slot 21, so that the process of pulling out the lock fastener 14 from the lock slot 21 becomes smoother.

[0060] Still referring to FIGS. 7 and 8, in order to ensure that the lock fastener 14 can be securely locked in the lock slot 21, in this embodiment, the first clock fastener 1 further includes a first elastic component 15. The first elastic component 15 is located in the first housing 11 and is compressed between the second part of the lock fastener 14 and the boss 111. The elastic direction of the first elastic component 15 is the same as the moving direction of the lock fastener 14. That is, the first elastic component 15 can always apply a force to move the lock fastener 14 towards the first position.

[0061] FIG. 10 is a schematic diagram of the assembly process of the first clock fastener 1 and the second clock fastener 2. The white arrows indicate the assembly sequence, and the solid arrows indicate the moving direction of the components. FIG. 11 is a schematic diagram of the disassembly process of the first clock fastener 1 and the second clock fastener 2. The white arrows indicate the assembly sequence, and the solid arrows indicate the moving direction of the components. Referring to FIGS. 10 and 11, the assembly process and disassembly process of the first clock fastener 1 and the second clock fastener 2 due to the action of the first elastic component 15 will be described below.

[0062] When the locking fastener 14 is in the initial state (the lock between the locking fastener 14 and the lock slot 21 is released), due to the action of the first elastic component 15, the locking fastener 14 is located at the first position (refer to the upper figure in Fig. 10). In the process of inserting the locking fastener 14 into the lock slot 21, the top of the first locking arm 142 abuts against the first inclined surface 212. Due to the action of the first inclined surface 212, the locking fastener 14 moves from the first position to the second position, compressing the first elastic component 15 to avoid the first protrusion 211 (refer to the middle figure in Fig. 10). After the first protrusion 211 is avoided, the elastic potential energy of the first elastic component 15 is released, driving the locking fastener 14 from the second position to the first position. In this case, since the first protrusion 211 is inserted into the first notch 143, the locking fastener 14 and the lock slot 21 are locked (refer to the lower figure in Fig. 10).

[0063] When the locking fastener 14 is in the initial state (the locking fastener 14 and the lock slot 21 are locked), due to the action of the first elastic component 15, the locking fastener 14 is located at the first position (refer to the upper figure in Fig. 11). In the process of pulling out the locking fastener 14 from the lock slot 21, the locking fastener 14 moves from the first position to the second position, compressing the first elastic component 15 until the top of the first locking arm 142 abuts against the second inclined surface 213 (refer to the middle part of Fig. 11). Due to the action of the second inclined surface 213, the locking fastener 14 is gradually pulled out from the lock slot 21, so the lock between the locking fastener 14 and the lock slot 21 is released (refer to the lower figure in Fig. 11). After the locking fastener 14 is pulled out from the lock slot 21, the elastic potential energy of the first elastic component 15 is released, driving the locking fastener 14 from the second position to the first position. In this case, the locking fastener 14 is reset and waits for the next locking operation.

[0064] Figure 12 shows a second fitting method between the lock fastener 14 and the lock slot 21. Similarly, since the lock fastener 14 is inserted into the lock slot 21, the lock fastener 14 and the lock slot 21 are locked. Since the lock fastener 14 is pulled out from the lock slot 21, the lock between the lock fastener 14 and the lock slot 21 is released. The main differences are that the driving method of the lock fastener 14 is different and the first position and the second position are different positions. This will be described below.

[0065] Figure 13 is a schematic diagram of the locked state between the lock fastener 14 and the lock slot 21 in this fitting method. Figure 14 is a schematic diagram of the state where the lock between the lock fastener 14 and the lock slot 21 is released in this fitting method.

[0066] Referring to FIGS. 13 and 14, in this embodiment, the second portion of the lock fastener 14 is located between the edge portion and the central portion of the second clock fastener 2. When the second portion of the lock fastener 14 is located at the first position of the lock slot 21, the second portion of the lock fastener 14 is near the central portion of the second clock fastener 2, and the second portion of the lock fastener 14 and the lock slot 21 are locked to each other. When the second portion of the lock fastener 14 is located at the second position of the lock slot 21, the second portion of the lock fastener 14 is near the edge portion of the second clock fastener 2, and the mutual lock between the second portion of the lock fastener 14 and the lock slot 21 is released.

[0067] Specifically, in this fitting method between the lock fastener 14 and the lock slot 21, when the user needs to operate the lock fastener 14 to lock the lock fastener 14 and the lock slot 21, the lock fastener 14 moves toward the central portion of the second clock fastener 2 or when it is necessary to release the lock between the lock fastener 14 and the lock slot 21, the lock fastener 14 moves toward the edge portion of the second clock fastener 2. In this way, the lock fastener 14 and the lock slot 21 are locked or unlocked.

[0068] In addition, in the process of the second part of the locking fastener 14 moving between the first position and the second position, the first part of the locking fastener 14 always moves between the edge of the first housing 11 and the boss 111. In this case, the locking fastener 14 does not interfere with the boss 111. That is, it does not affect the accommodation space A located at the top of the boss 111.

[0069] FIG. 15 is an exploded view of the first watch fastener 1. FIG. 16 is a schematic assembly view of the locking fastener 14. The solid-line arrow in FIG. 16 indicates the moving direction of the locking fastener 14. Referring to FIGS. 15 and 16, in this embodiment, the locking fastener 14 includes a drive block 144, a second slide block 145, and a second locking arm 146. The first part of the drive block 144 is located in the first housing 11, the second part of the drive block 144 is located outside the first housing 11, and the drive block 144 is movable relative to the first housing 11. The second slide block 145 is movably inserted into the first housing 11 and is in sliding contact with the drive block 144. There is an inner angle between the moving direction of the second slide block 145 and the moving direction of the drive block 144. The first part of the second locking arm 146 is connected to the first part of the second slide block 145 and is located on the side of the second slide block 145 away from the inner bottom surface of the first housing 11. The second part of the second locking arm 146 is located outside the first housing 11, and a second notch 147 is provided on the side wall of the second part of the second locking arm 146.

[0070] Since the second part of the drive block 144 is located outside the first housing 11, the user can move the first part of the drive block 144 located in the first housing 11 by moving the second part of the drive block 144. In addition, the first part of the drive block 144 is in contact with the second slide block 145, and the second locking arm 146 is connected to the second slide block 145. Therefore, the second locking arm 146 also moves together in the process of moving the drive block 144.

[0071] In the above implementation, there is an extrusion inclined surface on the side in the moving direction of the driving block 144. There is an inner angle of 45° between the extrusion inclined surface and the moving direction of the driving block 144. There is an extrusion inclined surface on the side in the moving direction of the second slide block 145. There is an inner angle of 45° between the extrusion inclined surface and the moving direction of the second slide block 145. The extrusion inclined surface of the driving block 144 is slidably fitted with the extrusion inclined surface of the second slide block 145. When the driving block 144 is moved, due to the action of the two extrusion inclined surfaces, a part of the force exerted on the second slide block 145 by the driving block 144 changes into a component force perpendicular to the moving direction of the driving block 144. Due to this component force, the second slide block 145 is driven and moved along the moving direction perpendicular to the driving block 144.

[0072] Referring to FIGS. 13 and 14, a second protrusion 214 is provided on the inner wall of the lock slot 21. The second protrusion 214 is located at the slot opening of the lock slot 21, and the second protrusion 214 faces the second notch 147.

[0073] When the driving block 144 drives the second slide block 145 to move the second part of the second lock arm 146 towards the center of the second clock fastener 2 and the second protrusion 214 is located in the second notch 147, the lock fastener 14 and the lock slot 21 are locked to each other. When the second slide block 145 drives the second part of the second lock arm 146 to move away from the center of the second clock fastener 2 and the second protrusion 214 is located outside the second notch 147, the mutual locking between the lock fastener 14 and the lock slot 21 is released.

[0074] Still referring to FIGS. 13 and 14, in order to make the process of inserting the lock fastener 14 into the lock slot 21 smoother, in this embodiment, a third inclined surface 215 is provided on the side of the second protrusion 214 closer to the slot opening of the lock slot 21. In the direction away from the center of the second clock fastener 2, the third inclined surface 215 is inclined from the slot opening of the lock slot 21 towards the slot bottom. In this design, during the process of inserting the lock fastener 14 into the lock slot 21, the top of the lock fastener 14 abuts against the third inclined surface 215 and moves from the first position to the second position along the third inclined surface 215 to avoid the second protrusion 214. In this way, the lock fastener 14 is gradually inserted into the lock slot 21, and the process of inserting the lock fastener 14 into the lock slot 21 becomes smoother.

[0075] Correspondingly, in order to make the process of pulling the lock fastener 14 out of the lock slot 21 smoother, a fourth inclined surface 216 is further provided on the inner wall of the lock slot 21. The fourth inclined surface 216 faces the third inclined surface 215. In the direction away from the center of the second clock fastener 2, the fourth inclined surface 216 is inclined from the slot bottom of the lock slot 21 towards the slot opening. In this design, during the process of pulling the lock fastener 14 out of the lock slot 21, since the lock fastener 14 moves from the first position to the second position, the top of the lock fastener 14 abuts against the fourth inclined surface 216. Under the action of the fourth inclined surface 216, the lock fastener 14 is pushed out of the lock slot 21, so that the process of pulling the lock fastener 14 out of the lock slot 21 becomes smoother.

[0076] Still referring to FIGS. 13 and 14, in order to be able to securely lock the lock fastener 14 in the lock slot 21, in this embodiment, the first clock fastener 1 further includes a second elastic component 16.

[0077] The second elastic component 16 is located in the first housing 11 and is compressed between the second part of the locking fastener 14 and the inner wall of the first housing 11. The elastic direction of the second elastic component 16 is the same as the moving direction of the locking fastener 14. That is, the second elastic component 16 can always apply a force to move the locking fastener 14 towards the first position.

[0078] FIG. 17 is a schematic diagram of the assembly process of the first watch fastener 1 and the second watch fastener 2. The white arrows indicate the assembly order, and the solid arrows indicate the moving direction of the components. FIG. 18 is a schematic diagram of the disassembly process of the first watch fastener 1 and the second watch fastener 2. The white arrows indicate the assembly order, and the solid arrows indicate the moving direction of the components. With reference to FIGS. 17 and 18, the assembly process and disassembly process of the first watch fastener 1 and the second watch fastener 2 due to the action of the second elastic component 16 will be described below.

[0079] When the locking fastener 14 is in the initial state (the lock between the locking fastener 14 and the lock slot 21 is released), the locking fastener 14 is located at the first position due to the action of the second elastic component 16 (see the upper figure in FIG. 17). In the process of inserting the locking fastener 14 into the lock slot 21, the top of the second locking arm 146 abuts against the third inclined surface 215. Due to the action of the third inclined surface 215, the locking fastener 14 moves from the first position to the second position, compressing the second elastic component 16 to avoid the second protrusion 214 (see the middle figure in FIG. 17). After the second protrusion 214 is avoided, the elastic potential energy of the second elastic component 16 is released, and the locking fastener 14 is driven from the second position to the first position. In this case, since the second protrusion 214 is inserted into the second notch 147, the locking fastener 14 and the lock slot 21 are locked (see the lower figure in FIG. 17).

[0080] When the locking fastener 14 is in the initial state (the locking fastener 14 and the lock slot 21 are locked), the locking fastener 14 is located at the first position by the action of the second elastic component 16 (see the upper figure in FIG. 18). In the process of pulling out the locking fastener 14 from the lock slot 21, the locking fastener 14 moves from the first position to the second position, compressing the second elastic component 16 until the top of the second locking arm 146 abuts against the fourth inclined surface 216 (see the middle figure in FIG. 18). Due to the action of the fourth inclined surface 216, the locking fastener 14 is gradually pushed out from the lock slot 21, and the lock between the locking fastener 14 and the lock slot 21 is released (see the lower figure in FIG. 18). When the lock fastener 14 is pulled out from the lock slot 21, the elastic potential energy of the second elastic component 16 is released, and the locking fastener 14 is driven from the second position to the first position. In this case, the locking fastener 14 is reset and waits for the next locking operation.

[0081] FIG. 19 is an exploded view of the first watch fastener 1 and the second watch fastener 2. Referring to FIG. 19, in this embodiment, the first magnetic component 17 is arranged on the first watch fastener 1. The second magnetic component 22 is arranged on the second watch fastener 2, and the second magnetic component 22 and the first magnetic component 17 are attracted to each other. In this design, when the first watch fastener 1 is fastened to the second watch fastener 2, the first magnetic component 17 and the second magnetic component 22 are attracted to each other. Due to this magnetic force, the first watch fastener 1 and the second watch fastener 2 automatically approach each other, and are locked to each other by the fitting of the locking fastener 14 and the lock slot 21.

[0082] FIG. 20 is a schematic diagram of the structure of a watch according to an embodiment of the present application. Please refer to FIG. 20. The watch is a smart watch and includes a watch dial 100, a watch band 200, and an electronic device 300.
