[0001] The present application claims priority to the Chinese patent application No. 202410819350.4, filed on June 24, 2024, and entitled “Connector, watchband assembly, and wearable device”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of electronic devices, and more particularly, to a connector, a watchband assembly, and a wearable device. BACKGROUND

[0003] With the continuous improvement of living standards, people pay more and more attention to their own health. To meet user needs, more and more wearable devices integrate health detection functions, such as blood pressure measurement functions, etc. In order to accurately obtain the results of health monitoring functions, wearable devices can be used with accessories, for example, blood pressure measurement functions can generally be used with airbags.

[0004] In order to ensure the accuracy of the measurement, the accessories of the wearable device are usually designed to be non-detachable, so when the accessories need to be replaced, the user generally can only replace them through after-sales service, and the operation of replacing the accessories is complex and the replacement cost is high.

[0005] How to improve the efficiency of mounting and dismounting the accessories of the wearable device is a problem to be considered. SUMMARY

[0006] The present application provides a connector, a watchband assembly, and a wearable device, the connector can be used to realize detachable connection between a main body of the wearable device and an accessory of the wearable device, and the mounting and dismounting efficiency between the main body of the wearable device and the accessory of the wearable device is high.

[0007] In a first aspect, a connector for connecting a watchband and an accessory is provided, the connector comprising: a first mounting member for connecting the watchband, and a second mounting member for connecting the accessory, the first mounting member comprising a first clamping portion, a locking portion, and an elastic structure, the first clamping portion comprising a first contact surface, the locking portion being fixedly connected with the first clamping portion, and the elastic structure being accommodated in the first mounting member, the locking portion being configured to drive the first clamping portion to move in a first direction, and the elastic structure being configured to push the first clamping portion to move in a direction opposite to the first direction; the second mounting member comprising a second clamping portion, the second clamping portion comprising a second contact surface; in a case where the first mounting member and the second mounting member are assembled, the first contact surface and the second contact surface are in abutment, and at least part of the first contact surface and at least part of the second contact surface are parallel to the first direction.

[0008] In a possible implementation, the first mounting member and the watchband can be connected through snap connection, magnetic attraction, screw connection, etc.

[0009] In a possible implementation, the second mounting member can include a main body portion and a protruding portion, wherein the main body portion of the second mounting member is connected with the accessory, and the protruding portion of the second mounting member includes the second clamping portion.

[0010] In a possible implementation, the first direction can be substantially the width direction of the watchband, or the first direction can also be substantially the thickness direction of the watchband.

[0011] In the technical solution, the first mounting member and the second mounting member can be connected through snap connection. During disassembly, the user can exert a force on the brake portion of the first mounting member to push the first clamping portion to move a distance in the first direction, so that the first clamping portion and the second clamping portion are unlocked. On this basis, the user can easily separate the second mounting member connected with the accessory from the first mounting member connected with the watchband, and the disassembly efficiency is high. During assembly, the elastic structure member can generate a force to push the first clamping portion to move a distance in the opposite direction of the first direction, so that the first clamping portion and the second clamping portion are locked. On this basis, the accessory can be relatively fixed with the watchband, the assembly efficiency is high, and the accessory is firmly connected with the watchband.

[0012] In combination with the first aspect, in some implementations of the first aspect, the brake portion is at least partially exposed on the surface of the connecting member.

[0013] Exemplarily, the connecting member can include left and right surfaces arranged opposite to each other substantially along the width direction of the watchband, upper and lower surfaces arranged opposite to each other substantially along the thickness direction of the watchband, and front and rear surfaces arranged opposite to each other substantially along the length direction (extending direction) of the watchband. The lower surface of the connecting member can face the watchband.

[0014] In a possible implementation, the first direction is substantially the width direction of the watchband, and the first mounting member can be provided with a through hole in the width direction of the watchband, and one end of the brake portion can pass through the through hole and be exposed on the left or right surface of the watchband. In this case, the brake portion can be a portion of the first mounting member extending in the width direction of the watchband, or a movable portion of the first mounting member having a certain length in the width direction of the watchband.

[0015] In a possible implementation, the first direction is substantially a thickness direction of the watchband, the first mounting member can be provided with a through hole in the thickness direction of the watchband, and one end of the brake part can pass through the through hole and be exposed on the upper surface of the watchband. In this case, the brake part can be a part of the first mounting member extending in the thickness direction of the watchband, or a movable part of the first mounting member having a certain height in the thickness direction of the watchband.

[0016] In the technical solution, the brake part is exposed on the surface of the connecting member, so that the user can quickly find the brake part during disassembly, and the disassembly of the accessory can be completed after the user simply applies a force to the brake part, and the disassembly efficiency between the first mounting member and the second mounting member is higher.

[0017] With reference to the first aspect, in some implementations of the first aspect, the first mounting member further includes a driven part, which is configured to push the second mounting member to move in a second direction when the first clamping part moves in the first direction, the second direction being perpendicular to the first direction.

[0018] In some scenarios, the first direction is substantially a width direction of the watchband, and the second direction is substantially a length direction or an extension direction of the watchband.

[0019] In a possible implementation, the driven part can be relatively fixed with the clamping part and the brake part on the first mounting member. The driven part and the brake part can be located on the same side of the first mounting member in the width direction of the watchband, and the clamping part can be located on the other side of the first mounting member in the width direction of the watchband, or in other words, the driven part can be close to the brake part and away from the clamping part.

[0020] In the technical solution, the first mounting member is provided with the driven part, so that, during disassembly, the driven part can push the second mounting member to move a certain distance in a direction away from the first mounting member when the user pushes the brake part in the first direction, and on this basis, the user can conveniently take out the first mounting member and the second mounting member after separation, and the disassembly efficiency of the connecting member is higher.

[0021] With reference to the first aspect, in some implementations of the first aspect, the driven part includes a first inclined surface, the second mounting member includes a second inclined surface, the first inclined surface and the second inclined surface are oppositely arranged, and the included angle a between the first inclined surface and the first direction and the included angle β between the second inclined surface and the first direction respectively satisfy: 0°<a<90°, 90°<β<180°.

[0022] In a possible implementation, a+β=180°. In other words, the first inclined surface and the second inclined surface can be parallel to each other.

[0023] During the disassembling process, the first inclined surface and the second inclined surface arranged oppositely can contact each other, and the two inclined surfaces can generate a friction force acting on each other, the friction force can guide the second mounting member to slide out of the first mounting member along the first inclined surface to a certain extent, and on this basis, the disassembling efficiency between the first mounting member and the second mounting member is higher.

[0024] In combination with the first aspect, in some implementations of the first aspect, the first mounting member includes a fixed member and a movable member, the fixed member includes the first accommodating groove, the elastic structural member is at least partially accommodated in the first accommodating groove, the movable member includes a braking portion and a first clamping portion, the first end of the elastic structural member abuts against the movable member, and the second end of the elastic structural member arranged opposite to the first end abuts against the inner wall of the first accommodating groove.

[0025] In a possible implementation, the first direction is substantially the width direction of the watchband, and the first accommodating groove can extend substantially along the width direction of the watchband. The movable member has a certain moving space in the width direction of the watchband. The first end of the elastic structural member can abut against a partial area of a left side wall or a partial area of a right side wall of the movable member arranged in the width direction of the watchband. The second end of the elastic structural member can abut against a partial area of a left inner wall or a partial area of a right inner wall of the first accommodating groove arranged in the width direction of the watchband. In other words, the abutment surface of the elastic structural member abutting against the movable member and the abutment surface of the elastic structural member abutting against the inner wall of the first accommodating groove are both substantially perpendicular to the first direction.

[0026] In a possible implementation, when mounted in the first mounting member, the elastic structural member can be in a compressed state, or in other words, the distance between the two ends of the elastic structural member can be smaller than the distance in a natural state of the elastic structural member.

[0027] In the technical solution, when an external force acts on the braking portion, the first clamping portion is close to the inner wall of the first accommodating groove, and the length of the elastic structural member is shortened. When the external force is removed, the elastic structural member restores the deformation and gradually extends, and the elastic structural member can push the movable member to move to a position in a state of being acted on by the external force. On this basis, the first mounting member and the second mounting member can be disassembled and mounted multiple times, and the structure and function of the connecting member have high reliability.

[0028] In combination with the first aspect, in some implementations of the first aspect, the first clamping portion is located on a side of the first accommodating groove close to the braking portion, and the first end of the elastic structural member abuts against the first clamping portion of the movable member.

[0029] In a possible implementation, the first clamping portion can be partially accommodated in the first accommodating groove.

[0030] The elastic structure is directly connected with the clamping part at one end, and the force of the elastic structure can directly act on the clamping part, thereby improving the reliability of the connecting piece.

[0031] In some implementations of the first aspect, the movable piece further comprises a baffle, the baffle is at least partially located in the first accommodating groove, the baffle is located on the side of the movable piece away from the second mounting piece, and the baffle is in abutment with the first end of the elastic structure.

[0032] In a possible implementation, the baffle can be located in a middle region, a left region or a right region in the width direction of the movable piece. In other words, the baffle can be arranged close to the brake part, or arranged close to the clamping part, or the baffle is located between the brake part and the clamping part in the width direction of the movable piece.

[0033] In the technical solution, the accommodating groove is arranged on the fixed piece to accommodate the elastic structure and the baffle, and the baffle is separately arranged on the movable piece and connected with the elastic structure. On the one hand, this scheme is beneficial to improve the space utilization of the fixed piece, and on the other hand, it can decouple the structures with different functions of the movable piece, thereby simplifying the complexity of the connecting piece structure.

[0034] In some implementations of the first aspect, the fixed piece further comprises a through hole, and the brake part comprises a push rod, the push rod being accommodated in the through hole.

[0035] In a possible implementation, the first direction is substantially the width direction of the watchband, and the axial direction of the through hole on the fixed piece and the axial direction of the push rod of the brake part can also be substantially along the width direction of the watchband.

[0036] In the technical solution, the through hole can be used to limit the movement direction of the brake part to a certain extent, and the implementation of the technical solution is beneficial to improve the reliability of the connecting piece function. In addition, the arrangement of the through hole is beneficial to better expose the brake part to the surface of the connecting piece, thereby improving the disassembly efficiency of the first mounting piece and the second mounting piece.

[0037] In some implementations of the first aspect, the first clamping part comprises a third inclined surface, the second clamping part comprises a fourth inclined surface, the third inclined surface and the fourth inclined surface are arranged opposite to each other, and the included angle γ between the third inclined surface and the first direction and the included angle δ between the fourth inclined surface and the first direction satisfy: 0°<γ<90°, 90°<δ<180°.

[0038] In a possible implementation, the first direction in the technical solution can be substantially the width direction of the watchband.

[0039] In a possible implementation, γ+δ=180°, or in other words, the third inclined surface and the fourth inclined surface can be parallel to each other. In a possible implementation, the first direction in the technical solution can be substantially the width direction of the watchband.

[0040] In a possible implementation, the third inclined surface of the first clamping portion and the first abutting surface are two adjacent surfaces, and the fourth inclined surface of the second clamping portion and the second abutting surface are two adjacent surfaces. The position where the third inclined surface meets the first abutting surface can be provided with a chamfer, and similarly, the position where the fourth inclined surface meets the second abutting surface can also be provided with a chamfer.

[0041] During installation, the fourth inclined surface of the second clamping portion of the second mounting member can be in contact with the third inclined surface of the first clamping portion of the first mounting member, and the two inclined surfaces can generate a frictional force that interacts with each other. The frictional force can guide the second mounting member to be inserted into the first mounting member along the third inclined surface to some extent, and on this basis, the installation efficiency between the first mounting member and the second mounting member is higher.

[0042] With reference to the first aspect, in some implementations of the first aspect, the first direction is a width direction of the watchband.

[0043] In a possible implementation, the first mounting member can include, in the first direction, in sequence, a connector base, a fixed member, a brake portion of a movable member, a clamping portion of the movable member, and an elastic structure member, in the second direction, in sequence, the connector base, the fixed member, a driven portion of the movable member, and the brake portion of the movable member, and in the third direction, in sequence, the connector base, the movable member, and the fixed member.

[0044] In a possible implementation, the first mounting member can include, in the first direction, in sequence, a connector base, a fixed member, a clamping portion of a movable member, a baffle of the movable member, and a brake portion of the movable member, in the second direction, in sequence, the connector base, the fixed member, the baffle of the movable member, a driven portion of the movable member, and the brake portion of the movable member, and in the third direction, in sequence, the connector base, the movable member, and the fixed member.

[0045] In a possible implementation, the connector base includes an installation platform, and the movable member and the fixed member can be installed on the installation platform. The movable member is close to the installation platform, and the fixed member covers the movable member.

[0046] With reference to the first aspect, in some implementations of the first aspect, the first mounting member includes a movable member, the movable member includes a first clamping portion, a second receiving groove is formed on a side of the movable member close to the first clamping portion, and the second clamping portion is accommodated in the second receiving groove when the first mounting member is connected with the second mounting member.

[0047] In this scheme, the first direction is substantially along the thickness direction of the watchband. In other words, the clamping portion in the connector in this scheme can move substantially along the thickness direction of the watchband.

[0048] The technical solution provides another way of realizing the buckle connection of the first mounting member and the second mounting member and a scheme of realizing the mounting and dismounting of the first mounting member and the second mounting member based on the connection way. A user can press the brake part of the connecting member in the thickness direction of the watchband, so as to push the first mounting member out of the second accommodating groove, and the clamping part of the first mounting member is separated from the clamping part of the second mounting member.

[0049] In combination with the first aspect, in some implementations of the first aspect, the first clamping part comprises a first inclined surface, the first inclined surface is located on a side of the second accommodating groove close to the second mounting member, and an included angle θ of the first inclined surface with the first direction satisfies: 0°<θ<90°.

[0050] During the mounting process, the second clamping part of the second mounting member can be in contact with the first inclined surface of the first clamping part of the first mounting member, and the two inclined surfaces can generate a frictional force that interacts with each other. The frictional force can guide the second mounting member to be inserted into the first mounting member along the first inclined surface to a certain extent, and on this basis, the mounting efficiency between the first mounting member and the second mounting member is higher.

[0051] In combination with the first aspect, in some implementations of the first aspect, the movable member comprises a brake part, a first accommodating groove is formed on a side of the movable member away from the brake part, and an elastic structure member is accommodated in the first accommodating groove, and one end of the elastic structure member is in abutment with an inner wall of the first accommodating groove.

[0052] In a possible case, the elastic structure member in the first accommodating groove is in a compressed state.

[0053] In the technical solution, the first accommodating groove for accommodating the elastic structure member is arranged on the movable member, and the acting force of the elastic structure member can be directly applied to the movable member to push the movable member to move in the first direction. On the one hand, this is conducive to improving the space utilization rate of the movable member, and on the other hand, this is conducive to improving the reliability of the function of the connecting member.

[0054] In combination with the first aspect, in some implementations of the first aspect, the first mounting member further comprises a fixing member, the fixing member comprises an accommodating cavity, the movable member is accommodated in the accommodating cavity, and the oppositely arranged top surface and bottom surface of the fixing member respectively comprise a first opening and a second opening, the first opening and the second opening are both in communication with the accommodating cavity. The movable member comprises a stop part and a brake part, the brake part is accommodated in the first opening, the stop part is accommodated in the second opening, the stop part is located outside the brake part, a third opening is further formed in the side wall of the fixing member, and the third opening is in communication with the second accommodating groove.

[0055] In a possible implementation, the fixing member can be provided with a through hole in the thickness direction, an end of the through hole can be located on the top surface of the fixing member (i.e., the first opening described above), and the other end of the through hole can be located on the bottom surface of the fixing member (i.e., the second opening described above). The part of the through hole close to the top surface of the fixing member can be used to accommodate the brake part, and the part of the through hole close to the bottom surface of the fixing member can be used to accommodate the stop part.

[0056] In a possible implementation, the movable member can include a bottom plate and a brake part, the brake part being connected to the middle part of the bottom plate, and the outer peripheral part of the bottom plate can be regarded as the stop part described above.

[0057] In this scheme, the third opening can be arranged to face the second mounting member, and in the mounting process, the limiting part of the second mounting member can be inserted into the second accommodating groove through the third opening.

[0058] With reference to the first aspect, in some implementations of the first aspect, the second mounting member includes a connecting rod, an axial direction of the connecting rod being perpendicular to the first direction, and the connecting rod including a second clamping part.

[0059] In a possible implementation, the connecting rod can be a round rod, or in other words, the outer wall of the connecting rod can be a smooth curved surface, or in other words, the second clamping part of the connecting rod can include a smooth curved surface, thereby facilitating the insertion of the connecting rod into the second accommodating groove and improving the mounting efficiency of the first mounting member and the second mounting member.

[0060] With reference to the first aspect, in some implementations of the first aspect, the elastic structure is a spring, and a deformation direction of the spring is parallel to the first direction.

[0061] Here, the deformation direction of the spring can include the elongation direction and the shortening direction of the spring, and in a possible case, the elastic structure located in the first mounting member can be in a compressed state.

[0062] With reference to the first aspect, in some implementations of the first aspect, the accessory is an airbag, and the connecting member further includes a gas delivery channel, one end of the gas delivery channel being in communication with a gas delivery port of the watch body corresponding to the watch band, and the other end of the gas delivery channel being in communication with the airbag.

[0063] With reference to the first aspect, in some implementations of the first aspect, the second clamping part is accommodated in the accommodating cavity of the first mounting member.

[0129] Fig. 1 shows an electronic device 10 provided by an embodiment of the present application, which can be a bracelet or a watch. In some examples, the electronic device 10 can include a watch body 13, a watch band 20, a watch band 30, a watch buckle 16 and a accessory 40. The two sides of the watch body 13 can be fixedly connected with the watch band 20 and the watch band 30 respectively, and the watch buckle 16 can be located at one end of the watch band 20 or the watch band 30 away from the watch body 13. In the case that a user wears the electronic device 10, the watch buckle 16 can be used to realize the mutual connection of the watch band 20 and the watch band 30.

[0130] In some examples, the watch body 13 can include a watch shell, a cover plate, a circuit board assembly, a power supply module and a back cover. In some scenarios, the watch shell can also be referred to as the middle frame of the watch body 13. The cover plate and the back cover can be located at the two ends of the watch shell respectively, and the watch shell, the cover plate and the back cover can enclose a receiving cavity, and the circuit board assembly and the power supply module of the electronic device 10 can be accommodated in the receiving cavity.

[0131] The circuit board assembly can include a processing unit and one or more sensors, the processing unit can be used to control the sensors to perform measurements, detection operations, and the processing unit can also be used to process the detection results of the sensors.

[0133] The PPG sensor can be used to detect the heart rate, i.e., the number of heartbeats per unit time of the user. The air pressure sensor can be used to detect the pressure value between the human body and the electronic device 10. The ECG sensor can be used to detect the capacitance between the human body and the electronic device 10, which can reflect whether the human body and the electronic device 10 are in good contact and can be used for ECG detection. The ACC sensor can be used to detect the acceleration of the electronic device 10 in various directions (generally three axes, i.e., x, y, and z axes), and the value of the acceleration can be used to identify the posture of the electronic device 10 and for applications such as pedometers. The gyroscope sensor can be used to determine the motion posture of the electronic device 10. For example, the angular velocity of the electronic device 10 around the three axes (i.e., x, y, and z axes) can be determined by the gyroscope sensor, and these angular velocities can be used to reflect the motion state of the user.

[0134] It should be understood that the above description of the sensors in the electronic device 10 is exemplary only, and in actual applications, the electronic device 10 can also include more or fewer sensors, or use other sensors with the same or similar functions to replace the above-mentioned listed sensors, etc., which are not limited by the embodiments of the present application.

[0135] The power supply module can be used to supply power to electronic components (such as the processing unit and various sensors) in the electronic device 10, etc. Exemplarily, the power supply module can include a battery. In some examples, in the scenario of charging the electronic device 10, the electronic device 10 is connected with a power supply device, and the power supply module can receive the power input by the charging device and store the power for the battery.

[0136] In some examples, the watchband 20 and the watchband 30 can be connected to the watch body 13 in various ways, including but not limited to: spring rod interface connection, fixed rod interface connection, hook connection, magnetic attraction connection, or threaded connection, etc. The connection method of the watchband 20 or the watchband 30 with the watch body 13 will be described in detail below, which is not expanded here.

[0137] In some examples, the clasp 16 can include one or more of the following: a pin buckle, a fold buckle, a butterfly buckle, a hidden buckle, or the like.

[0138] In some examples, the accessory 40 can be a cuff for blood pressure detection, or an external electrode patch for electrocardiogram detection, or a sensor for ultraviolet intensity or light intensity detection, and the like, which are not limited in the present application.

[0139] In a possible implementation, the accessory 40 can be connected with the watchband 20 or the watchband 30, thereby being relatively fixed with the watch body 13.

[0140] In some examples, the electronic device 10 can further include an air pump and a solenoid valve, the accessory 40 can be a cuff for blood pressure detection, an air nozzle of the cuff can be in communication with the air pump of the electronic device 10, and the processing unit of the electronic device 10 can be further configured to control the air pump and the solenoid valve to inflate or deflate the cuff connected with the electronic device 10.

[0141] In order to simplify the connection mode of the accessory 40 with the electronic device 10 and improve the dismounting efficiency of the accessory 40, an embodiment of the present application provides a watchband connector, which can be used for detachable connection of the accessory 40 with the watchband 20 (or the watchband 30), and can also be used for detachable connection of the watchband 20 (or the watchband 30) with the watch body 13.

[0142] In some examples, the watchband connector can also be used for detachable connection of other components included in the electronic device 10. In the following examples, the watchband connector is used for detachable connection of the accessory 40 with the watchband 20 and for detachable connection of the watchband 20 with the watch body 13.

[0143] In some scenarios, the above-mentioned watchband connector can also be referred to as a watchband head particle, a watchband fixing head, or a watchband bolt, and the like.

[0144] As shown in FIG. 2, a watchband assembly provided by an embodiment of the present application can include a watchband 200, a watchband connector 300, and an accessory 40. One end of the watchband connector 300 is connected with the watchband 200, and the other end of the watchband connector 300 is connected with the accessory 40.

[0145] In order to reduce the space occupation of the watchband assembly, in some examples, the accessory 40 can be arranged along the length direction (direction D1 in FIG. 2) of the watchband 200. The length of the accessory 40 can be not greater than the length of the watchband 200, and the width (dimension in direction D2 in FIG. 2) of the accessory 40 can also be not greater than the width of the watchband 200. In some scenarios, the direction D1 can also be referred to as the extension direction of the watchband, and the direction D2 can also be referred to as the direction perpendicular to the extension direction of the watchband.

[0146] To reduce the thickness of the whole band assembly, in some examples, referring to FIG. 3, one end of the band 200 close to the watch body 13 can comprise a receiving groove 230, which can be regarded as a recess structure formed by locally recessing the inner surface (the side in contact with the user's skin) of the band 200 in the direction of the thickness of the band (direction D3 in FIG. 3), and the aforementioned band connector 300 can be accommodated in the receiving groove 230.

[0147] The band connector 300 can be relatively fixed to the band 200 in various ways. For example, the band connector 300a can be clamped in the receiving groove 230 of the band 200, or an adhesive material can be filled between the outer surface of the band connector 300 and the side wall of the receiving groove 230, which can be used to achieve the relative fixation of the band connector 300 to the band 200.

[0148] For example, as shown in FIG. 3, the end of the band 200 provided with the receiving groove 230 can be provided with a connecting portion 240, which can be strip-shaped or sheet-shaped. The two ends of the connecting portion 240 can be connected to the end portions of the two opposite side walls of the receiving groove 230, respectively, or the strip-shaped or sheet-shaped connecting portion 240 can cover the opening of the receiving groove 230. One or more through holes can be formed on the connecting portion 240, and one or more connecting columns can be provided on the band connector 300, which can pass through the through holes on the connecting portion 240, thereby achieving the relative fixation of the band connector 300 to the band 200.

[0149] Continuing to refer to FIG. 3, in order to enable the band connector 300 to be more firmly connected to the band 200, the inner wall of the aforementioned receiving groove 230 can be provided with a recess 231, which can cooperate with the protruding structure on the band connector 300. In the case where the band connector 300 is accommodated in the receiving groove 230, the protruding structure on the band connector 300 can be accommodated in the recess 231. For example, the number of recesses 231 can be two, and the two recesses 231 can be respectively located on the two opposite side walls of the receiving groove 230.

[0150] The shape of the receiving groove 230 can match the shape of the band connector 300, so that the band connector 300 can be better accommodated in the receiving groove 230. For example, part of the band connector 300 can protrude from the main body of the band connector 300, and accordingly, referring to FIG. 3, the vicinity of the receiving groove 230 can be provided with a groove 233, which can be used to accommodate the locally protruding structure of the aforementioned band connector 300a.

[0151] For example, in the case that the accessory 40 is an airbag, the connection portion 240 can be provided with two types of through holes, wherein the first type of through hole 241 corresponds to the connection column on the watchband connecting piece 300, and the second type of through hole 243 corresponds to the gas pipe on the watchband connecting piece 300. In the case that the watchband connecting piece 300 is assembled on the watchband 200, the connection column on the watchband connecting piece 300 can pass through the first type of through hole 241, and the gas pipe on the watchband connecting piece 300 can pass through the second type of through hole 243.

[0152] The shape of the first type of through hole 241 can match the cross-sectional shape of the connection column, and the shape of the second type of through hole 243 can match the cross-sectional shape of the gas pipe. For example, the cross-section of the connection column can be a rounded rectangle, the first type of through hole 241 can also be a rounded rectangle, and the size of the hole diameter of the first type of through hole 241 can be slightly larger than the size of the cross-section of the connection column. For example, the cross-section of the gas pipe can be a circle, the second type of through hole 243 can also be a circle, and the hole diameter of the second type of through hole 243 can be slightly larger than the hole diameter of the gas pipe.

[0153] In a possible implementation, the number of the above-mentioned first type of through hole 241 can be multiple, and in order to match the position of the air pump or the air outlet located in the watch body 13, the multiple first type of through holes 241 can be located on the same side of the second type of through hole 243, for example. In a possible implementation, in order to make the connection of different regions of the watchband 200 with the watch body 13 have the same or similar firmness, the number of the first type of through hole 241 can be even (for example, two), and the even number of first type of through holes 241 can be evenly distributed on both sides of the second type of through hole 243, or in other words, the second type of through hole 243 is located in the middle of the even number of first type of through holes 241.

[0154] In order to make the accessory 40 more firmly connected with the watchband 200, referring to FIG. 3, a plurality of adjustment holes 220 can be arranged on the watchband 200, which can be matched with the prongs on the watch buckle 16 for adjusting the tightness of the watchband when wearing the electronic device 10. These adjustment holes 220 can also be matched with the positioning columns on the accessory 40, when the positioning columns are inserted into the adjustment holes 220, the accessory 40 can be relatively fixed with the watchband 200. By inserting the positioning columns into different adjustment holes 220, the installation position of the accessory 40 on the watchband 200 can be adjusted.

[0155] In some examples, the watchband 200 can be further provided with an adjusting hole 210 at one end away from the accommodating groove 230, which can extend along the length direction of the watchband 200, or in other words, has a length in the length direction of the watchband 200, and the length of the adjusting hole 210 can be understood as its adjusting range. Different from the positioning column that can be inserted into the adjusting hole 220, the accessory 40 can be provided with another positioning column that can cooperate with the adjusting hole 210 to adjust the installation position of the accessory 40 on the watchband 200.

[0156] Referring to FIG. 4, in some examples, the side of the accessory 40 facing the watchband 200 can be provided with a positioning column 41, which can match the shape and size of the adjusting hole 220 of the watchband 200, and can be inserted into the adjusting hole 220, so as to reduce the probability of the accessory 40 from sliding or falling off after being installed on the watchband 200. In one possible case, one end of the positioning column 41 passing through the adjusting hole 220 can be provided with a limiting portion, which can limit the positioning column 41 from being pulled out of the adjusting hole 220 when the positioning column 41 is inserted into the adjusting hole 220, so as to make the connection between the accessory 40 and the watchband 200 more secure.

[0157] Continuing to refer to FIG. 4, in some examples, the side of the accessory 40 facing the watchband 200 can be provided with a positioning column 42, which can match the shape and size of the adjusting hole 210 of the watchband 200, and can be inserted into the adjusting hole 210, and one end of the positioning column 42 passing through the adjusting hole 210 can be provided with a limiting portion, which can limit the positioning column 42 from being pulled out of the adjusting hole 210 when the positioning column 42 is inserted into the adjusting hole 210, so as to make the connection between the accessory 40 and the watchband 200 more secure.

[0158] In one possible case, the watchband 200 has both the adjusting hole 210 and the adjusting hole 220, and the accessory 40 has both the positioning column 41 and the positioning column 42, and in this case, when the positioning column 41 of the accessory 40 is inserted into the adjusting hole 220 at different positions on the watchband 200, the positioning column 42 can be located at different positions in the adjusting hole 210 having a certain length, so that the positioning column 41 and the positioning column 42 cooperate with each other to enable the accessory 40 to be installed at different positions on the watchband 200.

[0159] In one possible implementation, the distance between the positioning post 41 and the positioning post 42 on the accessory 40 can match the distance between the adjustment hole 220 and the adjustment hole 210 on the watchband 200. For example, the distance between the positioning post 41 and the positioning post 42 can be equal to or approximately equal to the distance between the adjustment hole 220 and the adjustment hole 210 on the watchband 200 near the accommodation groove 230.

[0160] In some examples, the accessory 40 can be provided with a connecting plate 44 at one end of the aforementioned watchband connector 300a, which can be used to connect the accessory 40 and the watchband connector 300. For example, the connecting plate 44 can be inserted into the slot of the watchband connector 300. One or more through holes 45 can be formed on the connecting plate 44, which can be provided with internal threads corresponding to the through holes on the watchband connector 300. By means of fasteners such as screws, the accessory 40 and the watchband connector 300 can be connected to each other when the screws are screwed into the through holes 45 on the connecting plate 44 and the through holes on the watchband connector 300 at the same time.

[0161] In one possible case, the accessory 40 can be an air bag for measuring blood pressure. In this case, as shown in FIG. 4, the accessory 40 can be further provided with an air nozzle 43 near the aforementioned connecting plate 44. The outer wall of the air nozzle 43 can be provided with external threads for connecting the air nozzle 43 and the gas pipe on the watchband connector 300. The outer wall of the air nozzle 43 can also be provided with a sealing rubber ring, which can improve the sealing effect of the connection position to some extent and reduce the probability of air leakage during the inflation or deflation of the air bag.

[0162] The position of the air nozzle 43 on the accessory 40 can match the position of the gas pipe on the watchband connector 300. For example, if the gas pipe on the watchband connector 300 is located in the middle position, the air nozzle 43 on the accessory 40 can be located in the middle of the connecting plate 44. In this case, the connecting plate 44 can be considered as being composed of two parts located on both sides of the air nozzle 43. For another example, if the gas pipe on the watchband connector 300 is located at the edge position, the air nozzle 43 on the accessory 40 can be located at one side of the aforementioned connecting plate 44.

[0163] In some examples, the air nozzle 43 and the connecting plate 44 can be connected to each other, or in other words, the end of the air nozzle 43 near the connecting plate 44 can be integrated with the connecting plate 44. In some examples, the air nozzle 43 can be spaced apart from the connecting plate 44.

[0164] The specific connection mode of the accessory 40 and the watchband connector 300 will be described in detail below, which will not be expanded here.

[0165] The structure of the various watchband connectors 300 provided by the embodiments of the present application is described in the following examples, and the connection manner of the watchband connectors 300 with different structures, the watchband 200 and the accessory 40 is described based on the structure.

[0166] FIG. 5 shows a structural schematic diagram of a watchband connector 300a provided by an embodiment of the present application, and FIG. 6 shows an assembly schematic diagram of the watchband connector 300a, in which the fasteners such as screws are not shown.

[0167] In some examples, the watchband connector 300a can include a first mount and a second mount, the first mount can be used for the connection of the watchband connector 300a with the watchband 200, and the second mount can be used for the connection of the accessory 40 with the watchband connector 300a. As an example but not limitation, the first mount and the second mount can be connected through snap connection, thereby facilitating the installation and separation of the accessory 40 with the watchband 200. The first mount and the second mount can also be connected through one or more of various manners such as magnetic attraction connection, threaded connection, pin connection or rotary locking, which are described in the following examples by taking the snap connection between the two as an example.

[0168] In some examples, the watchband connector 300a can include a connector base 310, which can be used for the connection with the watchband 200. In some examples, the watchband connector 300a can include a connecting frame 340 and a fixing cover 350, which can be used for the connection with the accessory 40. In some examples, the watchband connector 300a can include a movable piece 330 and a fixed piece 320, which can cooperate with the aforementioned connector base 310, connecting frame 340 and fixing cover 350 to realize the detachable connection of the accessory 40 with the watchband connector 300a.

[0169] In the above scheme, the connector base 310, the movable piece 330 and the fixed piece 320 can all be regarded as part of the aforementioned first mount, and the connecting frame 340 and the fixing cover 350 can all be regarded as part of the aforementioned second mount.

[0170] In some examples, the watchband connector 300a can further include one or more fasteners (such as screws) 301, which can be used to realize the relative fixation between various components in the aforementioned watchband connector 300a. For example, when the watchband connector 300a simultaneously includes the aforementioned connector base 310, fixed piece 320, movable piece 330, connecting frame 340 and fixing cover 350, these components can be assembled into the watchband connector 300a as shown in FIG. 5 by means of the fasteners 301.

[0171] As shown in FIGS. 7-9, the structure of the connector base 310 of the watchband connector 300a is shown. FIG. 7 can be regarded as a front view of the watchband connector 300a, FIG. 8 is a view of section AA in FIG. 7, and FIG. 9 can be regarded as a back view of the watchband connector 300a. In some scenarios, the connector base 310 can also be regarded as a part of the first mounting member.

[0172] In some examples, the connector base 310 can include a body, and one or more regions of the body of the connector base 310 can extend away from the body of the connector base 310 (e.g., in the direction D3 or at an angle to the direction D3) to form one or more connection posts that can cooperate with the first type of through holes 241 formed in the watchband 200 to achieve the connection between the connector base 310 and the watchband 200. For example, the connector base 310 can be provided with a connection post 311a and a connection post 311b, and the watchband 200 can be correspondingly provided with two first type of through holes 241, and the connection post 311a and the connection post 311b can be inserted into and partially pass through the two first type of through holes 241, respectively, so that the watchband 200 can be fixed relative to the connector base 310.

[0173] In combination with FIG. 9, the connection post 311a and the connection post 311b each have a groove structure at an end away from the body of the connector base 310, for example, referred to as groove 312a and groove 312b, respectively. In the case where the watchband connector 300a is mounted on the watchband 200, the grooves 312a and 312b can cooperate with the structure on the watch body 13 to achieve the connection between the watchband 200 and the watch body 13. For example, the rear shell of the watch body 13 can have two openings, and the inside of the openings can be provided with protruding structures that can be popped out or retracted. The shape and size of the openings on the watch body 13 match the shape and size of the end faces of the connection post 311a and the connection post 311b, and the shape and size of the protruding structures inside the openings match the shape and size of the grooves 312a and 312b on the connection post 311a and the connection post 311b. When the watchband 200 is mounted on the watch body 13, the connection post 311a and the connection post 311b can be inserted into the two openings, respectively, and the protruding structures in the openings can be accommodated in the grooves 312a and 312b, so that the watchband 200 is locked with the watch body 13. When the watchband 200 is removed from the watch body 13, the protruding structures in the aforementioned openings can be retracted and no longer accommodated in the grooves 312a and 312b, so that the watchband 200 is unlocked from the watch body 13 and the two can be separated from each other.

[0174] The connecting base 310 can also achieve the connection of the watchband 200 and the watch body 13 in other ways. For example, the connecting base 310 can have one or more magnets, and the rear shell or side wall of the watch body 13 can have a corresponding number of magnets. The magnets on the connecting base 310 and the magnets on the watch body 13 are arranged, and the magnets on the connecting base 310 and the magnets on the watch body 13 can achieve the connection of the watchband 200 and the watch body 13 through magnetic attraction. For another example, the connecting base 310 can include one or more screw holes, and the watchband 200 and the watch body 13 can be connected to each other through the cooperation of the screw holes on the connecting base 310 and the screws.

[0175] Referring to FIG. 7, in some examples, in order to facilitate the mutual assembly with other components in the watchband connecting piece 300a, the connecting base 310 can have a mounting platform 315, which can include a relatively flat mounting surface, so that other components in the watchband connecting piece 300a can be stably placed on the mounting platform 315.

[0176] In some examples, the body of the connecting base 310 can also have one or more threaded holes with internal threads, which can cooperate with the holes on other components of the watchband connecting piece 300a to achieve the connection of the connecting base 310 and these components. For example, as shown in FIG. 7, the connecting base 310 can include threaded holes 319a and 319b, which can be located on both sides of the aforementioned mounting platform 315, and the axial direction of the threaded holes can be perpendicular to the mounting surface of the mounting platform 315. In other words, the axial direction of the threaded holes can be parallel to the direction D3 in FIG. 7.

[0177] One possible implementation is that the mounting platform 315 of the connecting base 310 can be provided with connecting columns 314a and 314b, and the aforementioned threaded holes 319a and 319b can be formed on the connecting columns 314a and 314b, respectively. The connecting columns 314a and 314b can be arranged at different positions as needed, for example, to avoid other components placed on the mounting platform 315.

[0178] For example, the aforementioned connecting columns 314a and 314b can be located on one side of the mounting platform 315, for example, the connecting columns 314a and 314b can be arranged on the side of the mounting platform 315 close to the connecting columns 311a and 311b along the direction D2 in the figure.

[0179] For example, the aforementioned connecting columns 314a and 314b can be located on opposite sides of the mounting platform 315, for example, the connecting column 314a can be located on the side close to the connecting column 311a, and the connecting column 314b can be located on the side away from the connecting column 311b.

[0180] In the case that the accessory 40 is an airbag, the connector base 310 can further have a gas delivery pipe, which can be used to connect the gas nozzle of the airbag with the gas pump in the watch body 13. Exemplarily, referring to FIG. 7, the gas delivery pipe can include a watch body connecting pipe 313a and an airbag connecting pipe 313b, which are in internal communication. Similar to the aforementioned connecting post 311a or 311b, the watch body connecting pipe 313a can extend away from the body of the connector base 310. A sealing rubber ring can be sleeved on the outer wall of the watch body connecting pipe 313a, which can be inserted into the gas port on the watch body 13, and the sealing rubber ring can improve the sealing effect of the connection position between the watch body connecting pipe 313a and the gas port on the watch body 13. The airbag connecting pipe 313b can be located on the mounting surface of the aforementioned mounting platform 315, and the axial direction of the airbag connecting pipe 313b can be parallel to the mounting surface of the mounting platform 315.

[0181] One possible case is that the airbag connecting pipe 313b has a relatively large diameter, so that the gas nozzle of the airbag can be inserted into the airbag connecting pipe 313b and in communication with the airbag. Alternatively, the airbag connecting pipe 313b can also have a similar shape as the watch body connecting pipe 313a, so that the airbag connecting pipe 313b can also be inserted into the gas port of the airbag and in communication with the airbag. Alternatively, both the watch body connecting pipe 313a and the airbag connecting pipe 313b can be tubular with a relatively large diameter, and the gas nozzle on the watch body 13 can also be inserted into the watch body connecting pipe 313a.

[0182] Referring to FIG. 8, exemplarily, the axial direction O1O1 of the watch body connecting pipe 313a and the axial direction O2O2 of the airbag connecting pipe 313b can form an included angle Ag1. In one possible implementation, in order to improve the wearing comfort of the watchband assembly, the size of the included angle Ag1 can be about 90°. In one possible implementation, in order to better inflate or deflate the airbag, the size of the included angle Ag1 can be close to 180°. Taking into account the above two factors, the size of the included angle Ag1 can satisfy: 90°<Ag1<180°.

[0183] In order to better connect (e.g., bond) the watchband connector 300a with the watchband 200, referring to FIG. 9, the connecting surface 317 of the connector base 310 can be a smooth curved surface, which can increase the contact area between the connector base 310 and the inner wall of the accommodating groove 230 on the watchband 200, so that the connection between the watchband connector 300a and the watchband 200 is more firm. In addition, during the process of installing the watchband connector 300a into the accommodating groove 230 of the watchband 200, or during the process of removing the watchband connector 300a from the accommodating groove 230, the smooth curved connecting surface 317 is beneficial to improve the efficiency of disassembling and assembling the watchband connector 300a.

[0184] With reference back to FIG. 7, in some examples, in order to prevent the components mounted on the mounting platform 315 from shaking left and right or sliding along the direction D2, the connecting base 310 can further include a limiting plate 315-1 and a limiting plate 315-2. The limiting plate 315-1 and the limiting plate 315-2 can be respectively located on the left and right sides of the mounting platform 315. Exemplarily, the limiting plate 315-1 and the limiting plate 315-2 can be rectangular plates, triangular plates, or various shapes, which are not limited in the present application.

[0185] In combination with FIGS. 3, 7 and 9, in some examples, the two sides of the connecting base 310 can further include protruding structures formed by the main body of the connecting base 310 protruding to the two sides respectively. For example, the two protruding structures located on the left and right sides of the connecting base 310 can be respectively referred to as the connecting lug 316a and the connecting lug 316b. The connecting lug 316a and the connecting lug 316b on the connecting base 310 can cooperate with the recess 231 on the inner wall of the accommodating groove 230 of the watchband 200, so that the connecting base 310 is better accommodated in the accommodating groove 230, realizing the relative fixation of the watchband connecting piece 300a and the watchband 200. A possible case is that the connecting lug 316a and the connecting lug 316b can be respectively located on the outer side of the limiting plate 315-1 and the limiting plate 315-2. Alternatively, the connecting lug 316a and the connecting lug 316b can be understood as the protruding structures formed by the partial area of the left side wall of the limiting plate 315-1 and the partial area of the right side wall of the limiting plate 315-2 protruding outward.

[0186] With reference to FIGS. 7 and 8, in some examples, the connecting base 310 can further include an extension part 318, which can be regarded as being formed by the side of the mounting platform 315 away from the connecting columns 311a and 311b extending outward. In the case that the accessory 40 is connected with the watchband connecting piece 300a, part of the accessory 40 can be carried on the extension part 318, facilitating the installation and disassembly of the accessory 40 and the watchband connecting piece 300a.

[0187] A possible case is that the extension part 318 can have a plurality of glue injection holes 318-1, which can be distributed on the extension part 318 substantially uniformly along the direction D2. In order to enable the watchband connecting piece 300a to be more firmly connected with the watchband 200, in the case that the watchband connecting piece 300a is accommodated in the accommodating groove 230 of the watchband 200, the adhesive material can be injected into the glue injection holes 318-1 on the connecting base 310, and the cured adhesive material can be adhered with the watchband 200 and form a columnar structure inserted in the glue injection holes 318-1, thereby realizing the relative fixation of the watchband connecting piece 300a and the watchband 200.

[0188] The movable piece 330 can be mounted on the mounting platform 315 of the connecting piece base 310. FIG. 10 shows a structural schematic diagram of the movable piece 330. In some scenarios, the movable piece 330 can be regarded as a part of the aforementioned first mounting piece.

[0189] In some examples, the movable piece 330 can include a clamping portion 335, which can be matched with the clamping portion on the connecting frame 340, so as to realize the clamping connection between the movable piece 330 and the connecting frame 340. In the case that the movable piece 330 is relatively fixed with the watchband 200 and the connecting frame 340 is relatively fixed with the accessory 40, the clamping connection between the movable piece 330 and the connecting frame 340 can also be understood as the clamping connection between the accessory 40 and the watchband 200.

[0190] For example, in combination with FIGS. 10 and 11, the clamping portion 335 can be generally columnar, and the clamping portion 335 can include an inclined surface 335-1, which can be inclined to the direction D2. Referring to FIG. 11, the included angle between the inclined surface 335-1 and the direction D2 is Ag2, and the included angle Ag2 can satisfy: 0°<Ag2<90°. In other words, the length (L1 in FIG. 11) of the end of the columnar clamping portion 335 close to the outer periphery of the movable piece 330 is smaller, and the length (L2 in FIG. 11) of the end of the columnar clamping portion 335 away from the outer periphery of the movable piece 330 is larger.

[0191] In a possible case, in the process of clamping the connecting frame 340 to the movable piece 330, the clamping portion on the connecting frame 340 can move in the direction opposite to the direction D1 to the direction close to the movable piece 330. When the inclined surface 335-1 of the clamping portion 335 contacts the clamping portion of the connecting frame 340, the connecting frame 340 can generally move along the inclined surface 335-1, which is conducive to improving the mounting efficiency between the connecting frame 340 and the movable piece 330 to a certain extent.

[0192] For example, the inclined surface 335-1 of the clamping portion 335 can be an inclined plane, or can be a curved surface with a certain curvature. Also for example, the inclined surface 335-1 can be the entire side surface of the clamping portion 335, or can be a partial area of the side surface of the clamping portion 335.

[0193] In order to improve the mounting firmness of the connecting frame 340 and reduce the probability of the connecting frame 340 sliding off the connecting piece base 310, referring to FIG. 11, in some examples, the clamping portion 335 can further include an abutting surface 335-2, which can be located on another side surface of the columnar clamping portion 335, which is different from the inclined surface 335-1. In a possible case, the abutting surface 335-2 and the inclined surface 335-1 are two adjacent side surfaces of the clamping portion 335.

[0194] In the case where the connecting frame 340 is mounted on the connecting base 310, part or all of the abutting surface 335-2 can be in contact with the abutting surface of the clamping portion on the connecting frame 340, and the two abutting surfaces can generate a frictional force that interacts with each other. In one possible case, the connecting frame 340 and the movable piece 330 can slide relative to each other in the direction D2 in the drawing. In order to reduce the probability of the relative sliding, the plane in which the two abutting surfaces are in contact can be parallel to the direction D2, that is, at least part of the abutting surface 335-2 of the clamping portion 335 is parallel to the direction D2. For example, the abutting surface 335-2 can be a curved surface with a certain curvature, and the middle region of the curved surface can be parallel to the direction D2.

[0195] In some examples, referring to FIG. 11, the position where the two adjacent side walls of the clamping portion 335 meet can be provided with a circular chamfer, and the chamfer can facilitate the disassembly of the connecting frame 340 and the movable piece 330.

[0196] Continuing to refer to FIG. 10, in order to facilitate disassembly, in some examples, the movable piece 330 can further be provided with a brake portion 331, which can be used to push the clamping portion 335 of the movable piece 330 to move in the direction D2. In one possible case, when the clamping portion 335 and the clamping portion of the connecting frame 340 abut each other, and the movable piece 330 and the connecting frame 340 are in a locked state, in response to the brake portion 331 pushing the clamping portion 335 to move a certain distance (for example, S) in the direction D2, the clamping portion 335 can gradually separate from the clamping portion of the connecting frame 340, until the movable piece 330 and the connecting frame 340 switch to an unlocked state, so that the accessory 40 can be separated from the watchband 200.

[0197] For example, the brake portion 331 can be rod-shaped or bar-shaped, and the axial direction of the rod-shaped brake portion 331 can be parallel to the direction D2. One end of the brake portion 331 can be fixedly connected to the aforementioned clamping portion 335, and the end of the brake portion 331 away from the clamping portion 335 can serve as a brake end, and the user can apply a pushing force to the brake portion 331 at the brake end, thereby pushing the movable piece 330 to move in the direction D2.

[0198] Since the movable piece 330 is mounted in the connecting base 310, in order to facilitate operation, the rod-shaped or bar-shaped brake portion 331 can have a certain length, that is, the brake portion 331 can extend from the end close to the clamping portion 335 to the end away from the clamping portion 335 by a distance, so that the brake end of the brake portion 331 can be as close as possible to the outer surface of the watchband connecting piece 300a. In one possible case, the end of the brake portion 331 away from the clamping portion 335 can be exposed outside the watchband connecting piece 300a, so that the user can push the brake portion 331 from the outer surface of the watchband 200, and the efficiency of separating the accessory 40 from the watchband 200 is higher.

[0199] Continuing to refer to FIG. 10, in order to enable the clamping portion 335 to return to the initial position after being pushed by the braking portion 331, the watchband connector 300a can further include an elastic structure 337, which can be fixedly connected with the clamping portion 335 of the movable piece 330.

[0200] In some examples, the elastic structure 337 and the clamping portion 335 can be located on the same side of the movable piece 330, for example, in FIG. 10, the elastic structure 337 and the clamping portion 335 are both located on the right side of the movable piece 330. In this way, during the process in which the external force acts on the braking portion 331 and pushes the movable piece 330 to move in the direction D2, the elastic structure 337 can be compressed and deformed, or in other words, the length of the elastic structure 337 in the direction D2 is shortened during the process in which the movable piece 330 moves in the direction D2. In the case where the external force is removed, the elastic structure 337 gradually recovers the deformation, and in this process, the length of the elastic structure 337 in the direction D2 gradually recovers, and the elastic structure 337 can push the clamping portion 335 to move a certain distance in the opposite direction of the direction D2, so that the clamping portion 335 can return to the initial position.

[0201] In some examples, the elastic structure 337 and the clamping portion 335 can be located on the two sides of the movable piece 330 opposite to each other, for example, the elastic structure 337 can be located on the left side of the movable piece 330, and the clamping portion 335 is located on the right side of the movable piece 330. In this way, during the process in which the external force acts on the braking portion 331 and pulls the movable piece 330 to move in the direction D2, the elastic structure 337 can be elongated and deformed, or in other words, the length of the elastic structure 337 in the direction D2 is elongated during the process in which the movable piece 330 moves in the direction D2. In the case where the external force is removed, the elastic structure 337 gradually recovers the deformation, and in this process, the length of the elastic structure 337 in the direction D2 gradually recovers, and the elastic structure 337 can pull the clamping portion 335 to move a certain distance in the opposite direction of the direction D2, so that the clamping portion 335 can return to the initial position.

[0202] Exemplarily, the elastic structure 337 can be a spring, a spring sheet or the like structure capable of deforming under the action of an external force and recovering the deformation after the external force is removed. In one possible case, one end of the elastic structure 337 is fixedly connected with the end of the clamping portion 335 away from the braking portion 331, and the deformation direction of the elastic structure 337 can be parallel to the direction D2, or the deformation direction of the elastic structure 337 can form an angle less than 90° with the direction D2. On this basis, during the process of recovering the deformation, the force acting on the clamping portion 335 by the elastic structure 337 at least has a component in the opposite direction of the direction D2, which can drive the clamping portion 335 to move in the opposite direction of the direction D2 until the initial position.

[0203] As a possible implementation, referring to FIG. 10, the movable piece 330 can include a plate-shaped body 332, and the aforementioned brake portion 331 and the clamping portion 335 can be located on two opposite corners of the plate-shaped body 332. In other words, the brake portion 331 and the clamping portion 335 can be fixedly connected through the plate-shaped body 332. In some examples, the plate-shaped body 332 can include an extension portion 339, which can be formed by a portion of the plate-shaped body 332 close to the brake portion 331 extending outward in a direction away from the clamping portion 335 by a distance. The brake portion 331 can be fixedly connected with the extension portion 339. By means of the extension portion 339, the brake end of the brake portion 331 can be closer to the outer surface of the watchband connector 300a, facilitating user operation.

[0204] Continuing to refer to FIG. 10, in order to improve the separation efficiency between the accessory 40 and the watchband connector 300a, a possible solution is that, during the process of the brake portion 331 pushing the clamping portion 335 to move in the direction D1, the connecting frame 340 can simultaneously move a distance in the direction D1 until it is separated from the movable piece 330, on the basis of which the user can conveniently take out the accessory 40 connected with the connecting frame 340.

[0205] In a possible implementation, the movable piece 330 can include a driven portion 333, which can be substantially columnar, and the driven portion 333 can include a slope 333-1 inclined to the direction D2. The slope 333-1 can be located on the side wall of the driven portion 333 facing the clamping portion 335 or the brake portion 331. Referring to FIG. 12, in some examples, the included angle between the slope 333-1 and the direction D2 is Ag3, which can be less than 90°.

[0206] A possible case is that the connecting frame 340 fixedly connected with the accessory 40 can have a slope oppositely arranged with the slope 333-1. In the scenario of taking out the accessory 40, the movable piece 330 moves in the direction D2, and the slope 333-1 can abut against the slope on the connecting frame 340, and the two slopes can generate a frictional force acting on each other. The frictional force acting on the slope on the connecting frame 340 can push the connecting frame 340 to move a distance in the direction D1 in FIG. 10, and the user can conveniently take out the accessory 40.

[0207] In combination with FIG. 10 and FIG. 12, the driven part 333 can be approximately prism-shaped, and the driven part 333 is located at one corner of the plate-shaped body 332, and the driven part 333 and the brake part 331 and the clamping part 335 are located at different corners of the plate-shaped body 332, respectively. The driven part 333 can include three side walls, two of which are approximately parallel to the direction D1 and the direction D2 in the drawing, in other words, the two side walls can be perpendicular to each other. The inclined surface 333-1 can be connected to the aforementioned two side walls, respectively. In some examples, the position where the adjacent two side walls of the three side walls of the driven part 333 meet can be provided with a circular chamfer, and the provision of the chamfer is beneficial to improve the disassembly efficiency between the connecting frame 340 and the movable piece 330.

[0208] In the case where the movable piece 330 simultaneously includes the brake part 331, the driven part 333 and the clamping part 335, the brake part 331, the driven part 333 and the clamping part 335 can be fixedly connected, and the brake part 331, the driven part 333 and the clamping part 335 are located at three different corners of the plate-shaped body 332 in FIG. 10, which is only exemplary. Exemplarily but not limitatively, the clamping part 335 can be located at the middle region of the side (right side) of the plate-shaped body 332 away from the brake part 331. Exemplarily but not limitatively, the driven part 333 can be located at the middle region of the side (upper side) of the plate-shaped body 332 away from the brake part 331.

[0209] In FIG. 10, the plate-shaped body of the movable piece 330 is approximately rectangular, and in some examples, as shown in FIG. 13, the plate-shaped body of the movable piece 330 can also be approximately T-shaped, in addition, the plate-shaped body of the movable piece 330 can also be triangular or parallelogram-shaped, etc., which is not limited in the present application.

[0210] The fixing piece 320 of the watchband connecting piece 300a can also be mounted on the mounting platform 315 of the connecting piece base 310. As shown in FIG. 14 and FIG. 15, the fixing piece 320 is a structural schematic view, and in some scenarios, the fixing piece 320 can also be regarded as part of the aforementioned first mounting piece. As shown in FIG. 16, the movable piece 330 and the fixing piece 320 are combined.

[0211] The fixing member 320 can be used to accommodate part or all of the aforementioned movable member 330. In some examples, the fixing member 320 can include an accommodation groove 325, which can be used to accommodate part or all of the aforementioned elastic structure member 337, and the accommodation groove 325 can extend along the direction D2 in FIG. 14. Exemplarily, in combination with FIGS. 14-16, one end of the elastic structure member 337 can abut against a side wall 325-1 of the accommodation groove 325, and the other end of the elastic structure member 337 is connected to the clamping portion 335 of the movable member 330. Here, the side wall 325-1 can be a side wall of the accommodation groove 325 that is substantially perpendicular to the direction D2. In the case where the elastic structure member 337 is partially or entirely accommodated in the accommodation groove 325, the elastic structure member 337 can be in a compressed state, or in other words, in this case, the elastic structure member 337 can generate a pressure acting on the side wall 325-1 of the accommodation groove 325 and the clamping portion 335, respectively.

[0212] In order to enable relative fixation between the movable member 330 and the fixing member 320, in some examples, the clamping portion 335 of the movable member 330 can also be partially or entirely accommodated in the accommodation groove 325, and during movement of the movable member 330 along the direction D2 in FIG. 14, the clamping portion 335 can move along the extension direction of the accommodation groove 325. In this scenario, the accommodation groove 325 can also be regarded as a guide rail that defines the movement direction of the movable member 330, and the clamping portion 335 can be regarded as a slider that slides in the guide rail.

[0213] In some examples, continuing to refer to FIG. 14, the fixing member 320 can further include an accommodation groove 323, which can be used to accommodate part or all of the aforementioned stop portion 331 of the movable member 330. The positions of the accommodation groove 323 and the aforementioned accommodation groove 325 can be set according to the relative positions of the stop portion 331 and the clamping portion 335 on the movable member 330. Exemplarily, the stop portion 331 and the clamping portion 335 on the movable member 330 can be located substantially on the same straight line, and accordingly, the accommodation groove 323 and the accommodation groove 325 on the fixing member 320 can also be located substantially on the same straight line. Exemplarily, the stop portion and the clamping portion on the movable member 330 can be located on the diagonal corners of the plate-shaped main body 332, and accordingly, the accommodation groove 323 and the accommodation groove 325 on the fixing member 320 can be located substantially on the diagonal corners.

[0214] Referring to FIG. 15, the side of the fixing member 320 close to the accommodation groove 323 can be provided with a through hole 329, which can be used to accommodate part or all of the stop portion 331 of the movable member 330, or in other words, the stop portion 331 of the movable member 330 can be partially or entirely inserted into the through hole 329. One possible case is that the through hole 329 can be in communication with the accommodation groove 323, and in this case, the through hole 329 and the accommodation groove 323 can jointly constitute the accommodation space of the stop portion 331.

[0215] In the case where the extension 339 is provided on the movable member 330, the receiving groove 323 on the fixed member 320 can also be used to accommodate part or all of the extension 339.

[0216] One possible case is that, as shown in FIG. 14, the receiving groove 323 and the receiving groove 325 of the fixed member 320 can be respectively provided on two connecting seats of the fixed member 320, for example, connecting seat 326a and connecting seat 326b. The through hole 329 can be provided on the side wall of the connecting seat 326a and communicate with the receiving groove 323.

[0217] In some examples, the fixed member 320 can also be provided with a receiving groove 322a and a receiving groove 322b, which can be respectively provided corresponding to the connecting column 314a and the connecting column 314b on the connecting member base 310 in FIG. 7. In the case where the fixed member 320 is installed on the connecting member base 310, the connecting column 314a and the connecting column 314b on the connecting member base 310 can be respectively accommodated in the receiving groove 322a and the receiving groove 322b. In other words, the groove wall of the receiving groove 322a and the groove wall of the receiving groove 322b can respectively surround the outer periphery of the connecting column 314a and the connecting column 314b.

[0218] In order to enable the fixed member 320 to be fixedly connected with the connecting member base 310, the bottom surface of the receiving groove 322a and the bottom surface of the receiving groove 322b can be respectively provided with a through hole 324a and a through hole 324b, so that, in the case where the fixed member 320 is installed on the connecting member base 310, the through hole 324a at the bottom of the receiving groove 322a can communicate with the threaded hole 319a on the connecting column 314a, and a fastener such as a screw can simultaneously pass through the through hole 324a and the threaded hole 319a and be engaged with the threads on the inner walls of the through hole 324a and the threaded hole 319a. Similarly, the through hole 324b at the bottom of the receiving groove 322b can communicate with the threaded hole 319b on the connecting column 314b, and a fastener such as a screw can simultaneously pass through the through hole 324b and the threaded hole 319b and be engaged with the threads on the inner walls of the through hole 324b and the threaded hole 319b. On this basis, the fixed member 320 and the connecting member base 310 can be relatively fixed.

[0219] In one possible implementation, as shown in FIG. 14, the receiving groove 322a and the receiving groove 322b can be respectively provided on the connecting seat 326a and the connecting seat 326b, wherein the receiving groove 322a can be located near the receiving groove 323, and the receiving groove 322b can be located near the receiving groove 325.

[0220] In some examples, the fixing member 320 can further include a connecting plate 321, which can be used to connect the aforementioned connecting seat 326a and the connecting seat 326b. Exemplarily, two ends of the connecting plate 321 can be connected to the bottom of the connecting seat 326a (near the bottom of the accommodating groove 323) and the bottom of the connecting seat 326b (near the bottom of the accommodating groove 325), respectively. The connecting seat 326a and the connecting seat 326b, as well as the connecting plate 321, can constitute a structure similar to a U-shaped groove, the connecting seat 326a and the connecting seat 326b can be regarded as the sidewalls of the U-shaped groove, and the connecting plate 321 can be regarded as the bottom of the U-shaped groove. In combination with FIG. 16, the plate-shaped body 332, the driven part 333, the brake part 331 and the clamping part 335 can be partially or entirely accommodated in the U-shaped groove.

[0221] Referring to FIG. 17, in the case where the movable member 330 is installed to the fixing member 320, the driven part 333 of the movable member 330 can be located in the aforementioned U-shaped groove and near the connecting seat 326a. When the elastic structure 337 is in a compressed state, the pressure of the elastic structure 337 acting on the clamping part 335 can push the movable member 330 to move in the direction opposite to the direction D2 in the drawing. In a possible case, the side of the driven part 333 close to the connecting seat 326a can abut against the sidewall of the connecting seat 326a, and the connecting seat 326a can limit the distance of the movable member 330 moving in the direction opposite to the direction D2, in this scenario, the connecting seat 326a can be regarded as a limiting member limiting the movement of the movable member 330, and the driven part 333 on the movable member 330 can be regarded as a stopper cooperating with the limiting member.

[0222] Continuing to refer to FIG. 17, in order to reduce the probability of the movable member 330 contacting and rubbing against the connecting seat 326b during the movement of the movable member 330 along the direction D2 in the drawing, and to improve the reliability of the function of the watchband connector 300a, the part of the plate-shaped body 332 away from the driven part 333 and close to the connecting seat 326b can be located above the aforementioned U-shaped groove, or in other words, the distance between the lower surface of the plate-shaped body 332 and the connecting plate 321 of the fixing member 320 is denoted as h1, and the distance between the top surface of the connecting seat 326b and the connecting plate 321 of the fixing member 320 is denoted as h2, here, h1 can be slightly greater than h2.

[0223] As a possible implementation manner, the plate-shaped body of the movable member 330 can have the T-shaped structure shown in FIG. 13, in the case where the movable member 330 is installed in the fixing member 320, the part of the plate-shaped body of the movable member 330 close to the connecting seat 326b is vacant, and the probability of the movable member 330 contacting and colliding against the connecting seat 326b during the movement of the movable member 330 along the direction D2 is lower.

[0224] With reference to FIG. 17, the columnar driven part 333 can have a certain height, and in the case where the movable part 330 is mounted on the fixed part 320, the top end surface of the driven part 333 can be in contact with the connecting plate 321 of the fixed part 320, and the plate-shaped body 332 and the connecting plate 321 of the fixed part 320 can form a socket 302, and the connecting frame 340 connected to the accessory 40 can be inserted into the socket 302 and buckled with the movable part 330.

[0225] With reference to FIGS. 7 and 14, in the case where the accessory 40 is an airbag, the connecting part base 310 can be provided with an airbag connecting pipe 313b, and correspondingly, the fixed part 320 can include a slot body 327, which can be used to accommodate part or all of the airbag connecting pipe 313b. Generally, the air nozzle of the airbag can be approximately in the shape of a circular pipe, and in this case, the outer wall of the airbag connecting pipe 313b can include a curved surface. In order to better match the outer wall of the airbag connecting pipe 313b and the inner wall of the slot body 327, the magnet wall of the slot body 327 can also include a curved surface. In some examples, corresponding to the position of the airbag connecting pipe 313b on the connecting part base 310, the slot body 327 can be provided at the end of the fixed part 320 away from the accommodation slot 323.

[0226] With reference to the foregoing description, the mounting surface of the mounting platform 315 of the connecting part base 310 can be approximately planar. In order to enable the fixed part 320 to be stably mounted on the mounting platform 315, with reference to FIG. 17, in some examples, the end surface of the top (the part away from the connecting plate 321) of the fixed part 320 can be located in the same plane. In other words, the end surface of the top of the aforementioned connecting seat 326a, the end surface of the top of the connecting seat 326b, and the end surface of the top of the side wall of the slot body 327 can be substantially located in the same plane.

[0227] With reference to FIG. 18, after the fixed part 320 and the movable part 330 are assembled with each other, the stop part 331 of the movable part 330 can be inserted into the through hole 329, and the end surface of the stop end of the stop part 331 can be exposed from the through hole 329 at the end of the connecting part base 310 close to the limiting plate 315-1, which facilitates the user to complete the separation of the accessory 40 and the watchband 200 by operating the stop part 331 (for example, by pressing the end surface of the stop part 331 with a needle).

[0228] In some examples, the limiting plate 315-1 of the connector base 310 can be close to the arresting portion 331 of the movable piece 330. One possible case is that, as shown in FIG. 18, the limiting plate 315-1 can avoid the arresting portion 331 of the movable piece 330. One possible case is that the limiting plate 315-1 can include a through hole corresponding to the arresting portion 331, and the arresting portion 331 can also pass through the through hole, and the arresting end of the arresting portion 331 can protrude from the through hole of the limiting plate 315-1. In other words, in this case, the through hole of the limiting plate 315-1 and the through hole 329 of the fixed piece 320 are communicated, and the arresting portion 331 can pass through the two through holes at the same time.

[0229] With continued reference to FIG. 18, the fixed piece 320 with the movable piece 330 mounted thereon can be capped on the connector base 310, or in other words, the fixed piece 320 with the movable piece 330 mounted thereon can be inverted on the connector base 310. In order to accommodate the fastener, in some examples, the fixed piece 320 can be provided with accommodation grooves 328a and 328b on the side opposite to the bottom of the accommodation grooves 322a and 322b, so that, in the case of screw tightening, the screw cap of the screw can be accommodated in the accommodation groove 328a or 328b, and the screw shank of the screw can be inserted into the threaded hole 319a or 319b, and the fastener will not protrude from the surface of the watchband connector 300a, which is conducive to reducing the probability of scratching or damaging other components during installation or disassembly.

[0230] As shown in FIGS. 19 and 20, the structure of the connecting frame 340 of the watchband connector 300a is shown schematically, and in some scenarios, the connecting frame 340 can also be regarded as part of the aforementioned second mounting piece.

[0231] In some examples, the connecting frame 340 can include a clamping portion 349, which can cooperate with the clamping portion 335 of the movable piece 330 in the aforementioned first mounting piece to achieve detachable connection of the connecting frame 340 and the movable piece 330.

[0232] As one possible implementation, part of the main body portion 342 of the connecting frame 340 can extend outwardly to form a protruding portion 341, and as shown in FIGS. 19 and 20, the side wall of the protruding portion 341 can have a notch 341-1 corresponding to the clamping portion 335 on the movable piece 330. In the case of mutual connection of the connecting frame 340 and the movable piece 330, part or all of the clamping portion 335 of the movable piece 330 can be accommodated in the notch 341-1. The clamping portion 349 can be located on one side of the notch 341-1, or in other words, the clamping portion 349 can be regarded as part of the side wall of the protruding portion 341, which can be adjacent to the notch 341-1.

[0233] Fig. 21 is a partial enlarged view of the clamping portion 349 of the connecting frame 340. The clamping portion 349 can include an abutting surface 349-1. When the connecting frame 340 is connected to the movable piece 330, the abutting surface 349-1 of the clamping portion 349 can be in contact with the abutting surface 335-2 of the clamping portion 335 of the movable piece 330. A frictional force can be generated between the two abutting surfaces, which can limit the relative sliding between the clamping portion 349 and the clamping portion 335, so that the connecting frame 340 can be more firmly connected to the movable piece 330.

[0234] As a possible implementation, the abutting surface 349-1 and the abutting surface 335-2 can both be parallel to the direction D2 in the figure. In this way, the frictional force generated between the two abutting surfaces can be parallel to the direction D2, thereby facilitating the limitation of the separation of the clamping portion 349 and the clamping portion 335 along the direction D2.

[0235] In order to facilitate the insertion of the connecting frame 340 into the socket 302 formed by the movable piece 330 and the fixed piece 320 along a direction perpendicular to the direction D2, the clamping portion 349 can include a bevel 349-2, which can be inclined to the direction D2. For example, referring to Fig. 21, the angle Ag4 between the bevel 349-2 and the direction D2 can satisfy: 90° < Ag4 < 180°.

[0236] As a possible implementation, the abutting surface 349-1 and the abutting surface 335-2 can both be parallel to the direction D2 in the figure. In this way, the frictional force generated between the two abutting surfaces can be parallel to the direction D2, thereby facilitating the limitation of the separation of the clamping portion 349 and the clamping portion 335 along the direction D2.

[0237] In order to facilitate the insertion of the connecting frame 340 into the socket 302 formed by the movable piece 330 and the fixed piece 320 along a direction perpendicular to the direction D2, the clamping portion 349 can include a bevel 349-2, which can be inclined to the direction D2. For example, referring to Fig. 21, the angle Ag4 between the bevel 349-2 and the direction D2 can satisfy: 90° < Ag4 < 180°.

[0238] In a possible case, in combination with FIG. 10, FIG. 20 and FIG. 22, the movable member 330 has a driven portion 333 with a slope 333-1, which contacts the slope 341-2 of the connecting frame 340 during the process of dismounting the connecting frame 340. Since both slopes are inclined to the direction D2, the friction between the two slopes is along the direction D2, or in other words, the friction between the two slopes has a component perpendicular to the direction D2, which can act on the connecting frame 340 and push the connecting frame 340 to move along the direction D1. In this way, the force acting on the brake portion 331 can push the connecting frame 340 out of the socket 302 during the process of dismounting the connecting frame 340, and the dismounting efficiency of the connecting frame 340 is higher.

[0239] In some examples, the connecting frame 340 can be connected with the accessory 40. For example, the main body portion 342 of the connecting frame 340 can be used to fixedly connect with the accessory 40.

[0240] As a possible implementation, referring to FIG. 19, the main body portion 342 of the connecting frame 340 can be a box-shaped structure with a sidewall opening, and the accessory 40 can be inserted into the box-shaped structure from the opening of the main body portion, or in other words, one end of the accessory 40 can be partially accommodated in the main body portion 342 of the box-shaped structure. The connecting frame 340 can include a bottom plate 345, which can have one or more fixing columns 347. The end of the accessory 40 accommodated in the main body portion 342 can correspondingly have one or more fixing holes. During the assembly of the accessory 40 and the connecting frame 340, the fixing columns 347 on the connecting frame 340 can pass through the connecting holes on the accessory 40, so that the accessory 40 can be relatively fixed with the connecting frame 340.

[0241] In combination with FIG. 19 and FIG. 20, the left and right sides of the bottom plate 345 can respectively have a step portion 344a and a step portion 344b. The step portion 344a can be close to the left sidewall 346a of the main body portion 342, and the step portion 344b can be close to the right sidewall 346b of the main body portion 342. In a possible case, the fixing cover 350 of the watchband connecting piece 300a and the connecting plate 44 of the accessory 40 can be accommodated in the main body portion 342 of the box-shaped structure. The connecting plate 44 can be close to the bottom plate 345, and the fixing cover 350 can be away from the bottom plate 345, or in other words, the bottom plate 345, the connecting plate 44 and the fixing cover 350 can be sequentially stacked. For example, the connecting plate 44 can be located between the step portion 344a and the step portion 344b, and the left and right sides of the fixing cover 350 can be lapped on the step surface 348a of the step portion 344a and the step surface 348b of the step portion 344b.

[0242] As shown in FIG. 23, a structure diagram of the fixing cover 350 of the watchband connector 300a is shown, and in some scenarios, the fixing cover 350 can also be regarded as a part of the second mounting member mentioned above.

[0243] In some examples, the fixing cover 350 can have one or more through holes 353, which can be arranged corresponding to the fixing posts 347 on the connecting frame 340. In one possible scenario, in combination with FIG. 20, the end of the fixing post 347 away from the bottom plate 345 is provided with a limiting portion 347-1, and the cross-sectional dimension of the limiting portion 347-1 is greater than the diameter of the fixing post 347. The hole diameter of the through hole 353 on the fixing cover 350 can be smaller than the cross-sectional dimension of the limiting portion 347-1 of the fixing post 347, and the hole diameter of the through hole 353 can be slightly larger than the diameter of the fixing post 347.

[0244] In some examples, the limiting portion 347-1 of the fixing post 347 can be formed by a machining process such as hot pressing. In one possible way, after the through hole on the accessory 40 and the through hole on the fixing cover 350 pass through the fixing post 347 in turn, the end of the fixing post 347 is deformed by hot pressing to form the limiting portion 347-1, so that the connecting frame 340, the accessory 40 and the fixing cover 350 can be relatively fixed.

[0245] Referring to FIGS. 24 and 25, the accessory 40 can have a connecting plate 44, and in the process of assembling the connecting plate 44, the connecting frame 340 and the fixing cover 350, the connecting plate 44 of the accessory 40 can extend into the interior of the connecting frame 340 from the opening position on the side wall of the main body portion 342 of the connecting frame 340. The connecting plate 44 can be provided with a through hole 45, which can be arranged corresponding to the fixing post 347 on the connecting frame 340, and the fixing post 347 can pass through the through hole 45. When the fixing cover 350 is installed on the connecting frame 340 through the fixing post 347, the connecting plate 44 of the accessory 40 can be regarded as being clamped between the bottom plate 345 of the connecting frame 340 and the fixing cover 350, so that the connecting plate 44, the connecting frame 340 and the fixing cover 350 can be relatively fixed.

[0246] In one possible scenario, the height of the fixing post 347 can be slightly smaller than the sum of the thickness of the connecting plate 44 and the thickness of the fixing cover 350, so that when the connecting plate 44 and the fixing cover 350 are both clamped on the fixing post 347, the connecting plate 44, the fixing cover 350 and the limiting portion 347-1 at the top end of the fixing post 347 can be in a state of mutual extrusion, which is conducive to improving the firmness of the connection among the three.

[0247] In the case that the accessory 40 is the airbag shown in FIG. 4, the accessory 40 further has an air nozzle 43 near the connecting plate 44. In some scenarios, the air nozzle 43 is substantially cylindrical. In order to enable the air nozzle 43 to be stably mounted between the connecting frame 340 and the fixing cover 350, in some examples, the connecting frame 340 can have a fan-shaped notch 343 on the side wall thereof, and the fixing cover 350 can have an arc-shaped connecting portion 351, the shapes and sizes of the fan-shaped notch 343 and the arc-shaped connecting portion 351 can match those of the air nozzle 43 of the airbag. During the assembly of the air nozzle 43, the connecting frame 340 and the fixing cover 350, the air nozzle 43 can be clamped in the fan-shaped notch 343, and the arc-shaped connecting portion 351 can cover the air nozzle 43. In one possible scenario, part of the air nozzle 43 can pass through the fan-shaped notch 343.

[0248] The schematic diagram 26-1, the schematic diagram 26-2 and the schematic diagram 26-3 in FIG. 26 substantially show the process of disassembling the accessory 40 from the watchband connecting piece 300a.

[0249] In the schematic diagram 26-1, the clamping portion 349 on the connecting frame 340 is buckled with the clamping portion 335 on the movable piece 330, and the abutting surface 349-1 of the clamping portion 349 abuts against the abutting surface 335-2 of the clamping portion 335, the friction between the two abutting surfaces can reduce the probability of mutual sliding of the connecting frame 340 and the movable piece 330. In addition, when the connecting frame 340 is buckled with the movable piece 330, the elastic structure 337 is in a compressed state, and the elastic structure 337 exerts a pressure on the clamping portion 335 of the movable piece 330, the direction of the pressure can be opposite to the direction D2, and the pressure can limit the clamping portion 335 from falling out of the notch 341-1 of the connecting frame 340. In general, the pressure of the elastic structure 337 and the friction between the clamping portion 349 and the clamping portion 335 can enable the connecting frame 340 and the movable piece 330 to be relatively stably connected.

[0250] In the schematic diagram 26-2, in response to the action of the external force F on the brake portion 331, the movable piece 330 moves along the width direction (the direction D2) of the watchband 200, and the elastic structure 337 connected with the clamping portion 335 is further compressed under the action of the external force F, and the length is shortened, until the clamping portion 335 is pushed out of the notch 341-1 of the connecting frame 340, and the movable piece 330 and the connecting frame 340 are in an unlocked state.

[0251] In the schematic view 26-3, after the clamping portion 335 is pushed out of the gap 341-1, if the external force F continues to act on the brake portion 331, the inclined surface 333-1 of the driven portion 333 of the movable member 330 can contact the inclined surface 341-2 of the connecting frame 340, and a frictional force between the two inclined surfaces can be generated, which has a component in the direction D1 that can push the connecting frame 340 to move in the direction D1.

[0252] In the process of assembling the accessory 40 to the watchband connector 300a, the connecting frame 340 can be inserted into the socket 302 in the direction opposite to the direction D1 shown in FIG. 26, so that the connecting frame 340 is buckled to the movable member 330. In this process, the inclined surface 349-2 of the clamping portion 349 of the connecting frame 340 contacts the inclined surface 335-1 of the clamping portion 335 of the movable member 330 and generates a frictional force that can push the clamping portion 335 to move in the direction D2, and the elastic structure 337 fixedly connected to the clamping portion 335 is in a compressed state. When the connecting frame 340 extends into the socket 302, the clamping portion 335 of the movable member 330 is inserted into the gap 341-1 of the connecting frame 340 under the pushing of the elastic structure 337, the abutting surface 349-1 of the connecting frame 340 contacts the abutting surface 335-2 of the movable member 330, and a frictional force between the two abutting surfaces can be generated, which can limit the movement of the connecting frame 340, so that the accessory 40 is stably connected to the watchband connector 300a.

[0253] FIG. 27 shows a structural schematic view of another watchband connector 300b provided by an embodiment of the present application, and FIG. 28 shows a schematic view of constituent components of the watchband connector 300b, in which fasteners such as screws are not shown.

[0254] In some examples, the watchband connector 300b can include a first mounting member and a second mounting member, the first mounting member can be used for the connection of the watchband connector 300b to the watchband 200, and the second mounting member can be used for the connection of the accessory 40 to the watchband connector 300b. Exemplarily, the first mounting member and the second mounting member can be buckled to each other, thereby facilitating the mounting and dismounting of the accessory 40 to the watchband 200.

[0255] In some examples, the watchband connector 300b can include a connector base 410, which can be connected to the watchband 200. In some examples, the watchband connector 300b can include a connecting frame 440, which can be connected to the accessory 40. In some examples, the watchband connector 300b can include a movable member 430 and a fixed member 420, which can cooperate with the aforementioned connector base 410 and connecting frame 440 to achieve the detachable connection of the accessory 40 to the watchband connector 300b.

[0256] In the above solution, the connecting base 410, the fixing member 420 and the movable member 430 can be regarded as parts of the first mounting member, and the connecting frame 440 can be regarded as part of the second mounting member.

[0257] In some examples, the watchband connecting member 300b can further include one or more fasteners (e.g., screws) 401, which can be used to achieve the relative fixation between the various components in the watchband connecting member 300b. For example, when the watchband connecting member 300b includes the connecting base 410, the fixing member 420, the movable member 430 and the connecting frame 440, these components can be assembled into the watchband connecting member 300b as shown in FIG. 27 by means of the fasteners 401.

[0258] As shown in FIG. 29, the connecting base 410 of the watchband connecting member 300b can be regarded as part of the first mounting member in some scenarios.

[0259] In some examples, the connecting base 410 can include a body, and one or more regions of the body of the connecting base 410 can extend in a direction away from the body of the connecting base 410 (e.g., direction D3 or at an angle to the direction D3) to form one or more connecting columns, which can cooperate with the first type of through holes 241 formed on the watchband 200 to achieve the connection between the connecting base 410 and the watchband 200. For example, the connecting base 410 can be provided with a connecting column 411a and a connecting column 411b, and the watchband 200 can correspondingly have two first type of through holes 241, and the connecting column 411a and the connecting column 411b can be inserted into and partially pass through the two first type of through holes 241, respectively, so that the watchband 200 can be relatively fixed with the connecting base 410.

[0260] The connection between the connecting base 410 and the watchband 200 is similar to the connection between the connecting base 310 and the watchband 200, and details can be referred to the foregoing description of FIGS. 7-9, which will not be repeated here. It should be noted that the connecting base 410 and the watchband 200 can be connected in various ways, which are not limited in the present application.

[0261] In some examples, in order to facilitate the assembly with other components in the watchband connecting member 300b, the connecting base 410 can have a mounting platform 415, and the mounting surface of the mounting platform 415 is flat, which is conducive to the stable placement of other components in the watchband connecting member 300b on the mounting platform 415.

[0262] In some examples, the mounting platform 415 can include one or more connecting posts, which can be provided with threaded holes for connecting the connecting base 410 to other components. For example, as shown in FIG. 29, the mounting platform 415 of the connecting base 410 can be provided with a connecting post 414a and a connecting post 414b, which can be provided with a threaded hole 419a and a threaded hole 419b, respectively, which can be internally threaded and can be matched with the holes on other components of the watchband connecting piece 300b to achieve the fixed connection of the connecting base 410 and these components. For details of the connecting posts 414a and 414b and the threaded holes 419a and 419b, please refer to the description of the connecting posts 314a and 314b and the threaded holes 319a and 319b above, which will not be repeated here.

[0263] In the case of the accessory 40 being an airbag, the connecting base 410 can also have a gas delivery tube, which can be used to connect the air nozzle of the airbag to the air pump in the watch body 13. For example, the gas delivery tube can include a watch body connecting tube 413a and an airbag connecting tube 413b, which are in communication with each other.

[0264] For example, the axial direction of the watch body connecting tube 413a and the axial direction of the airbag connecting tube 413b can form an included angle Ag6, and the size of the included angle Ag6 can satisfy: 90°<Ag6<180°.

[0265] The shapes and structures of the watch body connecting tube 413a and the airbag connecting tube 413b are similar to those of the watch body connecting tube 313a and the airbag connecting tube 313b described above, and the relevant contents can be referred to the description above, which will not be repeated here.

[0266] In some examples, the connecting base 410 can also include a limiting plate 415-1 and a limiting plate 415-2, which can be respectively located on both sides of the mounting platform 415. The limiting plates can limit the left and right movement of other components on the mounting platform 415, thereby improving the structural reliability of the watchband connecting piece 300b.

[0267] In some examples, the connecting base 410 can also include a connecting ear 416a and a connecting ear 416b on both sides. The connecting ears 416a and 416b can be matched with the recesses 231 on the inner walls of the receiving grooves 230 of the watchband 200, so that the connecting base 410 is better accommodated in the receiving grooves 230, and the relative fixation of the watchband connecting piece 300b and the watchband 200 is achieved.

[0268] In some examples, the connecting lug 416a and the connecting lug 416b can be located outside the limiting plate 415-1 and the limiting plate 415-2 respectively. In other words, the connecting lug 416a and the connecting lug 416b can be understood as the protruding structures formed by the partial areas of the outer walls of the limiting plate 415-1 and the limiting plate 415-2 protruding outward.

[0269] In some examples, in order to increase the contact area between the connecting base 410 and the inner wall of the accommodating groove 230 on the watchband 200, so that the connection between the watchband connecting piece 300b and the watchband 200 is more firm, the back surface (the surface facing the accommodating groove 230) of the connecting base 410 can be provided as a smooth curved surface.

[0270] In some examples, the connecting base 410 can also be provided with an extension part, and one or more glue injection holes can be provided on the extension part. The relevant introduction of the extension part can refer to the relevant introduction of the extension part 318 of the connecting base 310 in the foregoing, which will not be expanded here.

[0271] The shape and structure of the connecting base 410 are similar to those of the connecting base 310 in the foregoing, and the relevant details of the structure of the connecting base 410 can refer to the relevant description of the connecting base 310.

[0272] In some examples, the mounting platform 415 of the connecting base 410 can be mounted with a movable piece 430. FIG. 30 shows a structural schematic diagram of the movable piece 430, which can also be regarded as a part of the first mounting piece in some scenarios.

[0273] In some examples, the movable piece 430 can include a clamping part 435, which can cooperate with the clamping part on the connecting frame 440, so as to realize the clamping connection between the movable piece 430 and the connecting frame 440. In the case that the movable piece 430 is relatively fixed with the watchband 200 and the connecting frame 440 is relatively fixed with the accessory 40, the clamping connection between the movable piece 430 and the connecting frame 440 can also be understood as the clamping connection between the accessory 40 and the watchband 200.

[0274] Exemplarily, the clamping portion 435 can be substantially columnar, and in combination with FIG. 31, the clamping portion 435 can include a slope 435-1, which can be inclined to the direction D2. The included angle between the slope 435-1 and the direction D2 is Ag7, and Ag7 can satisfy: 0°<Ag7<90°. In one possible scenario, in the process of buckling connecting the connecting frame 440 to the movable piece 430, the clamping portion on the connecting frame 440 can move towards the movable piece 430 in the direction opposite to the direction D1 in the drawing, and when the slope 435-1 of the clamping portion 435 faces the clamping portion of the connecting frame 440, the connecting frame 440 can move substantially along the slope 435-1, which to some extent facilitates improving the mounting efficiency between the connecting frame 440 and the movable piece 430.

[0275] By way of example but not limitation, the slope 435-1 of the clamping portion 435 can be an inclined plane, or a curved surface with a certain curvature. Exemplarily, the slope 435-1 can be the entire side surface of the clamping portion 435, or a partial area of the side surface of the clamping portion 435.

[0276] In order to improve the mounting firmness of the connecting frame 440 and reduce the probability of the connecting frame 440 falling off from the connecting piece base 410, in some examples, the clamping portion 435 can further include an abutting surface 435-2, which can be located on another side surface of the columnar clamping portion 435, which is different from the slope 435-1. In one possible scenario, the abutting surface 435-2 and the slope 435-1 are two adjacent side surfaces of the clamping portion 435.

[0277] In the case where the connecting frame 440 is mounted to the connecting piece base 410, part or all of the abutting surface 435-2 can be in contact with the abutting surface of the clamping portion on the connecting frame 440, and the contact area of the two abutting surfaces can generate a frictional force that interacts with each other. In one possible scenario, the connecting frame 440 and the movable piece 430 can produce relative sliding in the direction D2 in the drawing, and in order to reduce the probability of relative sliding between the two, the plane where the aforementioned contact area of the two abutting surfaces is located can be parallel to the direction D2, in other words, at least part of the abutting surface 435-2 of the clamping portion 435 is parallel to the direction D2. For example, the abutting surface 435-2 can be a curved surface with a certain curvature, and the middle area of the curved surface can be parallel to the direction D2.

[0278] With reference back to FIG. 30, to facilitate the disassembly, in some examples, the movable piece 430 can be further provided with a brake portion 431, which can be used to push the clamping portion 435 of the movable piece 430 to move in the opposite direction of the direction D2 in the figure. One possible case is that when the clamping portion 435 and the clamping portion of the connecting frame 440 abut each other, the clamping portion 435 is in a locked state, and in response to the brake portion 431 pushing the clamping portion 435 to move a distance (for example, S) in the opposite direction of the direction D2, the clamping portion 435 can gradually separate from the clamping portion of the connecting frame 440 until the movable piece 430 and the connecting frame 440 switch to an unlocked state, so that the accessory 40 can be separated from the watchband 200.

[0279] Exemplarily, the brake portion 431 can be rod-shaped or bar-shaped, and the axial direction of the rod-shaped brake portion 431 can be parallel to the direction D2. One end of the brake portion 431 can be fixedly connected with the aforementioned clamping portion 435, and the end of the brake portion 431 away from the clamping portion 435 can serve as a brake end, and the user can apply an external force to the brake portion 431 at the brake end, thereby pushing the movable piece 430 to move in the opposite direction of the direction D2.

[0280] Since the movable piece 430 is installed in the connecting piece base 410, in order to facilitate operation, the rod-shaped or bar-shaped brake portion 431 can have a certain length, or in other words, the brake portion 431 can extend from the end close to the clamping portion 435 to the end away from the clamping portion 435 by a distance, so that the brake end of the brake portion 431 can be as close as possible to the outer surface of the watchband connecting piece 300b. One possible case is that the end of the brake portion 431 away from the clamping portion 435 (for example, referred to as the brake end) can be exposed outside the watchband connecting piece 300b, so that the user can push the brake portion 431 from the outer surface of the watchband 200, thereby achieving the separation of the accessory 40 from the watchband 200.

[0281] With reference back to FIG. 30, in order to enable the clamping portion 435 to return to the initial position after being pushed by the brake portion 431, the watchband connecting piece 300b can further include an elastic structural piece 437, which can be fixedly connected with the movable piece 430. During the process in which the external force acts on the brake portion 431 and pushes the movable piece 430 to move in the opposite direction of the direction D2, the elastic structural piece 437 can be compressed and deformed, or in other words, the length of the elastic structural piece 437 in the direction D2 can be shortened during the process in which the movable piece 430 moves in the opposite direction of the direction D2. In the case where the external force is removed, the elastic structural piece 437 gradually recovers the deformation, and in this process, the length of the elastic structural piece 437 in the direction D2 gradually recovers, and the elastic structural piece 437 can push the movable piece 430 to move a distance in the direction D2, thereby driving the clamping portion 435 to move to the initial position.

[0282] Exemplarily, the elastic structure 437 can be a spring, a spring sheet, or the like, which can be deformed under an external force and can restore the deformation after the external force is removed.

[0283] In some examples, the movable piece 430 can include a baffle 439, which can be located on the side of the movable piece 430 close to the driven part 433. Exemplarily, in FIG. 30, the movable piece 430 can include a plate-shaped body 432, the clamping part 435 is located on the left side of the plate-shaped body 432, the brake part 431 is located on the right side of the plate-shaped body 432, and the driven part 433 and the baffle 439 are both located on the upper part of the plate-shaped body 432. In some scenarios, the baffle 439 can be understood as a protruding part extending from the partial area of the upper side wall of the plate-shaped body 432 of the movable piece 430 to the direction away from the plate-shaped body 432. As an example but not limitation, the baffle 439 can be close to the left side of the plate-shaped body 432, or can be close to the right side of the plate-shaped body 432, or the baffle 439 can be located in the middle of the upper edge of the plate-shaped body 432.

[0284] One possible case is that one end of the elastic structure 437 is fixedly connected to the side of the baffle 439 away from the brake part 431, and the deformation direction of the elastic structure 437 can be parallel to the direction D2, or the deformation direction of the elastic structure 437 can form an included angle less than 90° with the direction D2. On this basis, in the process of restoring the deformation, the force of the elastic structure 437 acting on the baffle 439 at least has a component along the direction D2, so as to push the baffle 439 to move along the direction D2 until the initial position.

[0285] In order to improve the separation efficiency between the accessory 40 and the watchband connecting piece 300b, one possible solution is that in the process of pushing the clamping part 435 to move in the opposite direction of the direction D2 by the brake part 431, the connecting frame 440 can be simultaneously moved by a distance along the direction D1 until the movable piece 430 is separated, so that the user can conveniently take out the accessory 40.

[0286] Referring to FIGS. 30 and 32, in some examples, the movable piece 430 can include the driven part 433, which can be substantially columnar, and the driven part 433 can include an inclined surface 433-1, which can be inclined to the direction D2. The inclined surface 433-1 can be located on the side wall of the driven part 433 facing the clamping part 435. In some examples, the included angle between the inclined surface 433-1 and the direction D2 is Ag8, and the included angle Ag8 can satisfy: 0°<Ag8<90°.

[0287] In a possible scenario, the connecting frame 440 fixedly connected with the accessory 40 can have an inclined surface opposite to the inclined surface 433-1. In the scenario of taking out the accessory 40, the movable part 430 moves in the opposite direction of the direction D2, the inclined surface 433-1 can abut against the inclined surface on the connecting frame 440, and the two inclined surfaces can generate a frictional force that interacts with each other. The frictional force acts on the inclined surface on the connecting frame 440, and can push the connecting frame 440 to move a distance along the direction D1, so that the user can conveniently take out the accessory 40.

[0288] Exemplarily, the driven part 433 can be approximately in the shape of a triangular prism, the driven part 433 is located at one corner of the plate-shaped body 432 of the movable part 430, and the driven part 433 and the brake part 431 and the clamping part 435 are respectively located at different corners of the plate-shaped body 432 of the movable part 430. The driven part 433 can include three side walls, two of which are approximately parallel to the direction D1 and the direction D2 in the figure, in other words, the two side walls can be approximately perpendicular to each other. The inclined surface 433-1 can be connected with the two side walls respectively. In some examples, the position where the adjacent two side walls of the three side walls of the driven part 433 meet can be provided with a circular chamfer, and the provision of the chamfer is beneficial to improve the disassembly efficiency between the connecting frame 440 and the movable part 430.

[0289] In FIG. 30, the plate-shaped body of the movable part 430 is approximately in the shape of a rectangle, which is only exemplary, and in some examples, the plate-shaped body of the movable part 430 can also be approximately in the shape of a T letter, a triangle, or a parallelogram, etc., which is not limited in the present application.

[0290] As shown in FIG. 33, it is a structural schematic view of the fixed part 420 of the watchband connecting piece 300b, and in some scenarios, the fixed part 420 can also be regarded as a part of the first mounting part mentioned above. FIG. 34 shows a schematic view of the combination of the movable part 430 and the fixed part 420.

[0291] In some examples, the fixed part 420 can include a receiving groove 421, which can be used to accommodate the movable part 430.

[0292] In a possible scenario, the receiving groove 421 can include a sub-receiving groove 425 and a sub-receiving groove 429, and the sub-receiving groove 425 and the sub-receiving groove 429 can be in communication with each other. The sub-receiving groove 425 can be used to accommodate the baffle 439 of the movable part 430, and the sub-receiving groove 425 can also be used to accommodate the elastic structure 437; the sub-receiving groove 429 can be used to accommodate the clamping part 435 of the movable part 430.

[0293] Exemplarily, the extending direction of the sub- accommodating groove 425 can match the deforming direction of the elastic structure 437 located in the sub-accommodating groove 425. In combination with FIG. 34, the elastic structure 437 can be a spring, and the extending or shortening direction of the elastic structure 437 can be parallel to the direction D2 in the figure. On this basis, the extending direction of the sub-accommodating groove 425 can be parallel to the direction D2.

[0294] A possible case is that the elastic structure 437 is in a compressed state when the elastic structure 437 and the baffle 439 are simultaneously accommodated in the sub-accommodating groove 425, in which case one end of the elastic structure 437 can abut against the side wall 425-1 of the sub-accommodating groove 425, and the other end of the elastic structure 437 can abut against the baffle 439. Due to the tendency of the elastic structure 437 to restore the deformation, the two ends of the elastic structure 437 can respectively have a pressure acting on the side wall 425-1 of the sub-accommodating groove 425 and the baffle 439. Under the action of the pressure, the side of the baffle 439 away from the elastic structure 437 can abut against the side wall 425-2 of the sub-accommodating groove 425 away from the elastic structure 437, so that the elastic structure 437 and the baffle 439 can be relatively firmly accommodated in the sub-accommodating groove 425. Here, the side wall 425-1 and the side wall 425-2 can be two opposite side walls of the sub-accommodating groove 425 in the direction D2, and the side wall 425-1 and the side wall 425-2 can be substantially perpendicular to the direction D2.

[0295] The elastic structure 437 and the baffle 439 can be partially or entirely accommodated in the sub-accommodating groove 425. A possible case is that the width (the size in the direction D1 in the figure) of the sub-accommodating groove 425 can be greater than or equal to the width of the elastic structure 437 or the width of the baffle 439, in which case the elastic structure 437 and the baffle 439 can be entirely accommodated in the sub-accommodating groove 425. A possible case is that the width of the sub-accommodating groove 425 can be less than the width of the elastic structure 437 and the width of the baffle 439, in which case the elastic structure 437 and the baffle 439 can be partially accommodated in the sub-accommodating groove 425.

[0296] Exemplarily, the extending direction of the sub- accommodating groove 429 can be parallel to the direction D2. In some scenarios, the extending direction of the sub-accommodating groove 429 can be understood as the movable direction of the clamping portion 435. Alternatively, in the case that the clamping portion 435 is partially or entirely accommodated in the sub-accommodating groove 429, the sub-accommodating groove 429 can be understood as a track that defines the moving direction of the clamping portion 435, and the clamping portion 435 can be understood as a slider that moves in the track. The width (dimension in the direction D1 in the figure) of the sub-accommodating groove 429 can match the width of the clamping portion 435, or alternatively, the width of the sub-accommodating groove 429 can be slightly greater than the width of the clamping portion 435, so that the clamping portion 435 can have a certain space for movement in the sub-accommodating groove 429, and the probability of jamming of the clamping portion 435 during movement can be reduced.

[0297] As an example, the width of the clamping portion 435 of the movable member 430 is substantially the same as the width of the plate-shaped body 432, and in this case, the width of different parts of the sub-accommodating groove 429 is substantially uniform.

[0298] As an example, the width of the clamping portion 435 of the movable member 430 can be greater than or less than the width of the part of the plate-shaped body 432 of the movable member 430 that is connected to the clamping portion 435, and in this case, the sub-accommodating groove 429 can include two parts with different widths, wherein the first part of the sub-accommodating groove 429 is used to accommodate the clamping portion 435, and the second part of the sub-accommodating groove 429 is used to accommodate the part of the clamping portion 435 that is connected to the plate-shaped body 432.

[0299] With continued reference to FIG. 33, the side wall 426 of the accommodating groove 421 near the side of the movable member 430 where the clamping portion 431 is located can be provided with a through hole 423, which can be used to accommodate the aforementioned clamping portion 431. In one possible scenario, the clamping portion 431 is rod-shaped or bar-shaped, and the through hole 423 can be a circular hole or a square hole with a hole diameter slightly greater than the diameter of the clamping portion 431. As an example but not limitation, the axis of the through hole 423 can be parallel to the direction D2 in the figure.

[0300] In some examples, the fixed member 420 can further include an accommodating groove 422a and an accommodating groove 422b, which can be respectively provided corresponding to the connecting columns 414a and 414b on the connecting member base 410 in FIG. 29. In the case that the fixed member 420 is installed on the connecting member base 410, the connecting columns 414a and 414b on the connecting member base 410 can be respectively accommodated in the accommodating grooves 422a and 422b. Alternatively, the groove walls of the accommodating grooves 422a and 422b can respectively surround the outer periphery of the connecting columns 414a and 414b.

[0301] In order to enable the fixing member 420 to be fixedly connected with the connecting member base 410, the bottom surface of the accommodating groove 422a and the bottom surface of the accommodating groove 422b can be respectively provided with a through hole 424a and a through hole 424b, so that, when the fixing member 420 is installed on the connecting member base 410, the through hole 424a at the bottom of the accommodating groove 422a can be in communication with the threaded hole 419a on the connecting column 414a, and a fastener such as a screw can pass through the through hole 424a and the threaded hole 419a at the same time and be engaged with the threads on the inner walls of the through hole 424a and the threaded hole 419a. Similarly, the through hole 424b at the bottom of the accommodating groove 422b can be in communication with the threaded hole 419b on the connecting column 414b, and a fastener such as a screw can pass through the through hole 424b and the threaded hole 419b at the same time and be engaged with the threads on the inner walls of the through hole 424b and the threaded hole 419b. On this basis, the fixing member 420 and the connecting member base 410 can be relatively fixed.

[0302] In a possible implementation, referring to FIG. 33, the accommodating groove 422a and the accommodating groove 422b can be respectively provided on the side wall of the aforementioned accommodating groove 421 and located near the sub-accommodating groove 425. For example, the accommodating groove 422a can be located on the left side of the sub-accommodating groove 425, and the accommodating groove 422b can be located on the right side of the sub-accommodating groove 425.

[0303] Referring to FIGS. 29 and 33, in the case where the accessory 40 is an air bag, the connecting member base 410 can be provided with an air bag connecting pipe 413b, and correspondingly, the fixing member 420 can include a groove body 427, which can be used to accommodate part or all of the air bag connecting pipe 413b. Generally, the air nozzle of an air bag can be approximately in the shape of a circular tube, in which case the outer wall of the air bag connecting pipe 413b can include a curved surface. In order to enable the outer wall of the air bag connecting pipe 413b to better match the inner wall of the groove body 427, the groove body wall of the groove body 427 can also include a curved surface. In some examples, corresponding to the position of the air bag connecting pipe 413b on the connecting member base 410, the groove body 427 can be provided at the end of the fixing member 420 away from the side wall 426.

[0304] Referring to FIGS. 34 and 35, after the fixing member 420 and the movable member 430 are assembled with each other, the stop portion 431 of the movable member 430 can be inserted into the through hole 423, and the end face of the stop end of the stop portion 431 can be exposed from the end of the through hole 423 located on the surface of the connecting member base 410, so as to facilitate the user to complete the separation of the accessory 40 from the watchband 200 by operating the stop portion 431.

[0305] In some examples, as shown in FIG. 35, the limiting plate 415-1 of the connector base 410 can be close to the arresting portion 431 of the movable piece 430. It is possible that the limiting plate 415-1 can avoid the arresting portion 431 of the movable piece 430. It is possible that the limiting plate 415-1 can include a through hole corresponding to the arresting portion 431, and the arresting portion 431 can pass through the through hole, and the arresting end of the arresting portion 431 can protrude from the through hole of the limiting plate 415-1. In other words, in this case, the through hole of the limiting plate 415-1 and the through hole 423 of the fixed piece 420 are communicated, and the arresting portion 431 can pass through the two through holes at the same time.

[0306] Referring to FIG. 35, the fixed piece 420 with the movable piece 430 mounted thereon can be capped on the connector base 410, or in other words, the fixed piece 420 with the movable piece 430 mounted thereon can be inverted on the connector base 410. In order to accommodate the fastener, in some examples, the fixed piece 420 can be provided with accommodation grooves 428a and 428b on the side opposite to the bottom of the accommodation grooves 422a and 422b, so that in the case of screw tightening, the screw cap of the screw can be accommodated in the accommodation groove 428a or 428b, and the screw shank can be inserted into the threaded hole 419a or 419b, and the fastener will not protrude from the surface of the watchband connector 300b, which is beneficial to reduce the probability of scratching or damaging other components during installation or disassembly.

[0307] Continuing to refer to FIG. 35, the plate-shaped body of the movable piece 430 and the mounting platform 415 of the connector base 410 can form a socket 402, and the connecting frame 440 connected with the accessory 40 can be inserted into the fixed piece 420 and buckled with the movable piece 430 through the socket 402.

[0308] As shown in FIG. 36, it is a structural schematic diagram of the connecting frame 440 of the watchband connector 300b, and in some scenarios, the connecting frame 440 can also be regarded as part of the aforementioned second mounting piece.

[0309] In some examples, the connecting frame 440 can include a clamping portion 449, which can cooperate with the clamping portion 435 of the movable piece 430 in the aforementioned first mounting piece to achieve detachable connection between the connecting frame 440 and the movable piece 430.

[0310] As a possible implementation, the main body portion 444 of the connecting frame 440 can extend outwardly to form a protrusion 441, and the side wall of the protrusion 441 can have a notch 441-1, which can be arranged correspondingly to the clamping portion 435 on the movable piece 430, as shown in FIG. 36. In the case where the connecting frame 440 and the movable piece 430 are connected to each other, part or all of the clamping portion 435 of the movable piece 430 can be accommodated in the notch 441-1. The clamping portion 449 can be located at one side of the notch 441-1, or in other words, the clamping portion 449 can be regarded as a part of the side wall of the protrusion 441, which is adjacent to the notch 441-1.

[0311] FIG. 37 shows a partial enlarged view of the clamping portion 449 of the connecting frame 440. The clamping portion 449 can include an abutting surface 449-1, which can be in contact with the abutting surface 435-2 of the clamping portion 435 of the movable piece 430 in the case where the connecting frame 440 and the movable piece 430 are connected to each other. The friction between the two abutting surfaces can limit the relative sliding between the clamping portion 449 and the clamping portion 435, so that the connecting frame 440 can be more firmly connected to the movable piece 430.

[0312] As a possible implementation, the abutting surface 449-1 and the abutting surface 435-2 can both be parallel to the direction D2, so that the friction between the two abutting surfaces can be parallel to the direction D2, thereby facilitating the limitation of the separation of the clamping portion 449 and the clamping portion 435 along the direction D2.

[0313] Continuing to refer to FIG. 37, in order to facilitate the insertion of the connecting frame 440 into the aforementioned socket 402 along a direction perpendicular to the direction D2, the clamping portion 449 can include a bevel 449-2, which can be inclined to the direction D2. Exemplarily, the included angle Ag9 between the bevel 449-2 and the direction D2 can satisfy: 90° < Ag9 < 180°.

[0314] In a possible scenario, the inclined surface 449-2 can be arranged on the side of the clamping portion 449 away from the main body portion of the connecting frame 440. During the process of inserting the connecting frame 440 into the aforementioned accommodating cavity, the inclined surface 449-2 first contacts the inclined surface 435-1 of the clamping portion 435 of the movable piece 430. Since the inclined surface 449-2 and the inclined surface 435-1 are both inclined to the direction D2, the frictional force generated between the inclined surface 449-2 and the inclined surface 435-1 can be inclined to the direction D2, in other words, the frictional force generated between the inclined surface 449-2 and the inclined surface 435-1 has a component in the opposite direction of the direction D2, which can act on the clamping portion 435 of the movable piece 430 and push the clamping portion 435 to move in the opposite direction of the direction D2 and press the elastic structural piece 437, so that the elastic structural piece 437 is compressed and deformed. On this basis, the arrangement of the inclined surface 449-2 and the inclined surface 435-1 is conducive to improving the installation efficiency of the connecting frame 440.

[0315] In order to improve the dismounting efficiency of the connecting frame 440, the protruding portion 441 of the connecting frame 440 can be provided with an inclined surface 441-2 inclined to the direction D2, as shown in FIGS. 36 and 38.

[0316] In a possible scenario, the movable piece 430 has a driven portion 433 with an inclined surface 433-1, which contacts the inclined surface 441-2 of the connecting frame 440 during the process of dismounting the connecting frame 440. Since the two inclined surfaces are both inclined to the direction D2, the frictional force generated between the two inclined surfaces is along the direction D2, or in other words, the frictional force generated between the two inclined surfaces has a component perpendicular to the direction D2, which can act on the connecting frame 440 and push the connecting frame 440 to move in the direction of the direction D1, so that the force acting on the brake portion 431 can push the connecting frame 440 out of the socket 402 during the process of dismounting the connecting frame 440, and the dismounting efficiency of the connecting frame 440 is higher.

[0317] In some examples, the connecting frame 440 can be fixedly connected with the accessory 40. For example, the main body portion 444 of the connecting frame 440 can be used to be fixedly connected with the accessory 40.

[0318] Referring to FIG. 39, as one possible implementation, the main body portion 444 of the connecting frame 440 can include a sub-connecting portion 442a and a sub-connecting portion 442b, which are substantially plate-shaped, fixedly connected at their left and right ends, and spaced apart from each other at their middle portions. In other words, the oppositely arranged sub-connecting portion 442a and the sub-connecting portion 442b can form a socket 445 therebetween, which can be used to accommodate a portion of the accessory 40 and to achieve the connection between the connecting frame 440 and the accessory 40.

[0319] In some examples, one or more through holes can be formed in the thickness direction of the sub-connecting portion 442a or the sub-connecting portion 442b, which can be matched with through holes on the portion of the accessory 40 inserted into the socket 445, to achieve the connection between the accessory 40 and the connecting frame 440.

[0320] For example, referring to FIG. 39, the sub-connecting portion 442a can be provided with a connecting hole 447a and a connecting hole 447b in the thickness direction, which can be distributed along the length direction (direction D2) of the sub-connecting portion 442a.

[0321] Taking the airbag shown in FIG. 4 as an example, the connecting plate 44 of the accessory 40 can be provided with two through holes 45, which can be positioned corresponding to the connecting hole 447a and the connecting hole 447b on the sub-connecting portion 442a, and the inner walls of these connecting holes can be provided with internal threads. By means of fasteners such as screws, the accessory 40 can be connected with the watchband connecting piece 300b when the screws are screwed into the through holes 45 on the connecting plate 44 and the connecting hole 447a or the connecting hole 447b on the connecting frame 440 at the same time.

[0322] In the case where the accessory 40 is an airbag, the accessory 40 also has an air nozzle 43 near the connecting plate 44. In some scenarios, the air nozzle 43 is substantially cylindrical. In order to enable the air nozzle 43 to be stably mounted on the connecting frame 440, in some examples, referring to FIGS. 36, 39, 40 and 41, the main body portion 444 of the connecting frame 440 can be provided with a through hole 443 in the width direction (direction D1), and the shape and size of the through hole 443 can match those of the air nozzle 43 of the airbag. During the assembly of the air nozzle 43 and the connecting frame 340, the air nozzle 43 can be inserted into the through hole 443. In one possible case, part of the air nozzle 43 can pass through the through hole 443.

[0323] The positions of the socket 445 and the through hole 443 on the connecting frame 440 can correspond to the positions of the connecting plate 44 and the air nozzle 43 of the accessory 40. In a possible case, the connecting plate 44 and the air nozzle 43 are spaced apart, in which case, the socket 445 and the through hole 443 on the connecting frame 440 can also be spaced apart, or in other words, in this case, the socket 445 and the through hole 443 on the connecting frame 440 can not be in communication. In a possible case, the connecting plate 44 and the air nozzle 43 are adjacent, in which case, the socket 445 and the through hole 443 on the connecting frame 440 can be in communication with each other.

[0324] The schematic diagram 42-1, the schematic diagram 42-2 and the schematic diagram 42-3 in FIG. 42 generally show the process of detaching the accessory 40 from the watchband connector 300b.

[0325] In the schematic diagram 42-1, the clamping portion 449 on the connecting frame 440 is buckled with the clamping portion 435 on the movable piece 430, and the abutting surface 449-1 of the clamping portion 449 and the abutting surface 435-2 of the clamping portion 435 abut with each other, and the friction between the two abutting surfaces can reduce the probability of mutual separation of the connecting frame 440 and the movable piece 430. In addition, when the connecting frame 440 and the movable piece 430 are buckled, the elastic structure 437 is in a compressed state, and the elastic structure 437 has a pressure acting on the movable piece 430, and the direction of the pressure can be along the direction D2 in the drawing, and the pressure can limit the clamping portion 435 from sliding out of the gap 441-1 of the connecting frame 440. In general, the pressure of the elastic structure 437 and the friction between the clamping portion 449 and the clamping portion 435 can make the connecting frame 440 and the movable piece 430 relatively stable connection.

[0326] In the schematic diagram 42-2, in response to the action of the external force F acting on the brake portion 431, the movable piece 430 moves along the direction D2, and the elastic structure 437 connected with the clamping portion 435 is further compressed under the action of the external force, and the length is shortened, until the clamping portion 435 is pushed out of the gap 441-1 of the connecting frame 440, and the movable piece 430 and the connecting frame 440 are in an unlocked state.

[0327] In the schematic diagram 42-3, after the clamping portion 435 is pushed out of the gap 441-1, if the external force F continues to act on the brake portion 431, the inclined surface 433-1 of the driven portion 433 of the movable piece 430 can be in contact with the inclined surface 441-2 of the connecting frame 440, and a friction force can be generated between the two inclined surfaces, and the friction force has a component along the direction D1, which can push the connecting frame 440 to move along the direction D1.

[0328] During the assembly of the accessory 40 to the band connector 300b, the connecting frame 440 can be inserted into the socket 402 in the direction opposite to the direction D1 shown in FIG. 42, so that the connecting frame 440 is snap-connected with the movable piece 430. During this process, the inclined surface 449-2 of the clamping portion 449 of the connecting frame 440 and the abutting surface 435-2 of the clamping portion 435 of the movable piece 430 are in contact with each other and generate a friction force, which can push the clamping portion 435 to move along the direction D2, and the elastic structure 437 fixedly connected with the clamping portion 435 is in a compressed state. When the connecting frame 440 extends into the socket 402, the clamping portion 435 of the movable piece 430 is inserted into the gap 441-1 of the connecting frame 440 under the pushing of the elastic structure 437, and the abutting surface 449-1 of the connecting frame 440 and the abutting surface 435-2 of the movable piece 430 generate a friction force therebetween, which limits the movement of the connecting frame 440, so that the accessory 40 is stably connected with the band connector 300b.

[0329] FIG. 43 shows a structural schematic diagram of another band connector 300c provided by an embodiment of the present application, and FIG. 44 shows a schematic diagram of constituent components of the band connector 300c, in which fasteners such as screws are not shown.

[0330] In some examples, the band connector 300c can include a first mounting member and a second mounting member, the first mounting member can be used for the connection of the band connector 300c with the band 200, and the second mounting member can be used for the connection of the accessory 40 with the band connector 300c. Exemplarily, the first mounting member and the second mounting member can be snap-connected, so as to facilitate the mounting and separation of the accessory 40 with the band 200.

[0331] In some examples, the band connector 300c can include a connector base 510, which can be used for the connection with the band 200. In some examples, the band connector 300c can include a connecting frame 540, which can be used for the connection with the accessory 40. In some examples, the band connector 300c can include a movable piece 530 and a fixed piece 520, which can cooperate with the aforementioned connector base 510 and the connecting frame 540 to achieve the detachable connection of the accessory 40 with the band connector 300c.

[0332] In the above scheme, the connector base 510, the fixed piece 520 and the movable piece 530 can all be regarded as part of the aforementioned first mounting member, and the connecting frame 540 can be regarded as part of the aforementioned second mounting member.

[0333] In some examples, the watchband connector 300c can further include one or more fasteners (e.g., screws) 501, which can be used to achieve relative fixation between various components in the aforementioned watchband connector 300c. Exemplarily, in the case where the watchband connector 300c includes the aforementioned connector base 510, the fixing member 520, the movable member 530, and the connecting frame 540, these components can be assembled into the watchband connector 300c as shown in FIG. 43 by means of the fasteners 501 and the like.

[0334] As shown in FIG. 45, which is a structural schematic diagram of the connector base 510 of the watchband connector 300c, in some scenarios, the connector base 510 can be regarded as a part of the aforementioned first mounting member.

[0335] In some examples, the connector base 510 can include a body, one or more regions of the body of the connector base 510 can extend in a direction away from the body of the connector base 510 (e.g., the direction D3 or at an angle to the direction D3) to form one or more connecting posts, which can cooperate with the aforementioned first type of through holes 241 on the watchband 200 to achieve connection between the connector base 510 and the watchband 200. Exemplarily, the connector base 510 can be provided with a connecting post 511a and a connecting post 511b, and the watchband 200 can correspondingly have two first type of through holes 241, the connecting post 511a and the connecting post 511b can be inserted into and partially pass through the two first type of through holes 241 respectively, so that the watchband 200 can be relatively fixed with the connector base 510.

[0336] The connection manner between the connector base 510 and the watchband 200 is similar to the connection manner between the connector base 310 and the watchband 200 as described above, and details can be referred to the contents related to FIGS. 7-9 above, which will not be repeated here. It should be noted that the connector base 510 and the watchband 200 can be connected to each other in various ways, which are not limited in the present application.

[0337] In some examples, in order to facilitate mutual assembly with other components in the watchband connector 300c, the connector base 510 can have a mounting platform 515, the mounting surface of the mounting platform 515 is flat, which is conducive to the stable placement of other components in the watchband connector 300c on the mounting platform 515.

[0338] In some examples, the mounting platform 515 can include one or more connecting posts, which can be provided with threaded holes for connecting the connecting base 510 to other components. For example, as shown in FIG. 45, the mounting platform 515 of the connecting base 510 can be provided with a connecting post 514a and a connecting post 514b, which can be provided with a threaded hole 519a and a threaded hole 519b, respectively, which can be internally threaded and can be matched with the holes on other components of the watchband connecting piece 300c to achieve the fixed connection of the connecting base 510 and these components. For details of the connecting posts 514a and 514b and the threaded holes 519a and 519b, reference can be made to the description of the connecting posts 314a and 314b and the threaded holes 319a and 319b above, which will not be repeated here.

[0339] In the case of the accessory 40 being an airbag, the connecting base 510 can also have a gas delivery tube, which can be used to connect the air nozzle of the airbag to the air pump in the watch body 13. For example, the gas delivery tube can include a watch body connecting tube 513a and an airbag connecting tube 513b, which are in communication with each other.

[0340] For example, the axial direction of the watch body connecting tube 513a and the axial direction of the airbag connecting tube 513b can form an included angle Ag11, and the size of the included angle Ag11 can satisfy: 90°<Ag11<180°.

[0341] The shapes and structures of the watch body connecting tube 513a and the airbag connecting tube 513b are similar to those of the watch body connecting tube 313a and the airbag connecting tube 313b described above, and the relevant contents can be referred to the description above, which will not be repeated here.

[0342] Similar to the connecting surface 317 of the connecting base 310, the back surface (the surface attached to the watchband 200) of the connecting base 510 can also be a smooth curved surface, thereby increasing the contact area between the connecting base 510 and the inner wall of the accommodating groove 230 on the watchband 200, and making the connection between the watchband connecting piece 300c and the watchband 200 more secure. For details, reference can be made to the description of the connecting surface 317 above, which will not be repeated here.

[0343] In some examples, the connecting base 510 can also include a limiting plate 515-1 and a limiting plate 515-2, which can be respectively located on both sides of the mounting platform 515. The limiting plates can limit the left and right movement of other components on the mounting platform 515, thereby improving the structural reliability of the watchband connecting piece 300c.

[0344] In some examples, the two sides of the connecting piece base 510 can also include connecting ears 516a and 516b. The connecting ears 516a and 516b can cooperate with the recesses 231 on the inner walls of the accommodating grooves 230 of the watchband 200, so that the connecting piece base 510 is better accommodated in the accommodating grooves 230, realizing the relative fixation of the watchband connecting piece 300c and the watchband 200.

[0345] One possible implementation is that the connecting ears 516a and 516b can be located outside the limiting plates 515-1 and 515-2, respectively. In other words, the connecting ears 516a and 516b can be understood as protruding structures formed by the outward protrusion of the local areas of the outer walls of the limiting plates 515-1 and 515-2.

[0346] In some examples, the connecting piece base 510 can also be provided with an extension part, and one or more glue injection holes can be arranged on the extension part. The relevant description of the extension part can refer to the relevant description of the extension part 318 of the connecting piece base 310 in the foregoing.

[0347] The shape and structure of the connecting piece base 510 are similar to those of the connecting piece base 310 in the foregoing, and the relevant details of the structure of the connecting piece base 510 can refer to the relevant description of the connecting piece base 310.

[0348] In some examples, the mounting platform 515 of the connecting piece base 510 can be mounted with a movable piece 530. FIG. 46 shows a structural schematic view of the movable piece 530, which can be regarded as a part of the first mounting piece in some scenarios.

[0349] In some examples, the movable piece 530 can include a clamping part 535, which can cooperate with the clamping part on the connecting frame 540, so as to realize the clamping connection between the movable piece 530 and the connecting frame 540. In the case that the movable piece 530 is relatively fixed with the watchband 200 and the connecting frame 540 is relatively fixed with the accessory 40, the clamping connection between the movable piece 530 and the connecting frame 540 can also be understood as the clamping connection between the accessory 40 and the watchband 200.

[0350] One possible implementation is that the movable piece 530 can include a bottom plate 532, and the accommodating groove 534 is arranged on the bottom plate 532. The clamping part 535 can be understood as the side wall of one side of the accommodating groove 534.

[0351] Exemplarily, in combination with FIG. 47, the clamping portion 535 can include a slope 535-1, which can be inclined with respect to the direction D3. For example, the included angle between the slope 535-1 and the direction D3 is Ag12, which can satisfy: 0° < Ag12 < 90°. In one possible scenario, in the process of buckling the connecting frame 540 to the movable piece 530, the clamping portion on the connecting frame 540 can approach the movable piece 530 in the opposite direction of the direction D1 in FIG. 46, and when the slope 535-1 of the clamping portion 535 contacts the clamping portion of the connecting frame 540, the connecting frame 540 can move along the slope 535-1 approximately, which to some extent facilitates improving the mounting efficiency between the connecting frame 540 and the movable piece 530.

[0352] By way of example but not limitation, the slope 535-1 of the clamping portion 535 can be an inclined plane, or a curved surface with a certain curvature. Exemplarily, the slope 535-1 can be the entire side surface of the clamping portion 535 away from the accommodating groove 534, or can be a partial area of the side surface of the clamping portion 535.

[0353] In order to improve the mounting firmness of the connecting frame 540 and reduce the probability of the connecting frame 540 falling off from the connecting piece base 410, in some examples, the clamping portion 535 can further include an abutting surface 535-2, which can be the side surface of the clamping portion 535 close to the accommodating groove 534. In one possible scenario, the abutting surface 535-2 and the slope 535-1 are two adjacent side surfaces of the clamping portion 535. In one possible scenario, the abutting surface 535-2 and the slope 535-1 can be connected by a transition surface 535-3, which can be perpendicular to the direction D3.

[0354] In the case where the connecting frame 540 is mounted to the connecting piece base 510, part or all of the abutting surface 535-2 can contact the abutting surface of the clamping portion on the connecting frame 540, and the contact area of the two abutting surfaces can generate a frictional force that interacts with each other. In one possible scenario, the connecting frame 540 and the movable piece 530 can produce relative sliding along the direction D3 in the figure, in order to reduce the probability of relative sliding between the two, the plane where the aforementioned contact area of the two abutting surfaces can be parallel to the direction D3, in other words, at least part of the abutting surface 535-2 of the clamping portion 535 is parallel to the direction D3. For example, the abutting surface 535-2 can be a curved surface with a certain curvature, and the edge area of the curved surface can be parallel to the direction D3.

[0355] In one possible scenario, the clamping portion of the connecting frame 540 can be partially or entirely accommodated in the accommodating groove 534 when the connecting frame 540 is mounted to the connecting base 510, and the accommodating groove 534 can be shaped and sized to match the clamping portion of the connecting frame 540. For example, the clamping portion of the connecting frame 540 can be a round rod, and in this case, the accommodating groove 534 can be a circular groove with a diameter slightly larger than that of the aforementioned clamping portion in the form of a round rod.

[0356] With continued reference to FIGS. 46 and 47, to facilitate disassembly, in some examples, the movable piece 530 can further be provided with a braking portion 531 that can be used to push the clamping portion 535 of the movable piece 530 to move in the opposite direction of the direction D3. In one possible scenario, when the clamping portion 535 is in abutment with the clamping portion of the connecting frame 540 and the clamping portion 535 is in the locked state, in response to the braking portion 531 moving the clamping portion 535 a distance (e.g., S) in the opposite direction of the direction D3, the clamping portion 535 can gradually separate from the clamping portion of the connecting frame 540 until it is switched to the unlocked state, so that the accessory 40 can be separated from the watchband 200.

[0357] In one possible implementation, the middle region of the bottom plate 532 of the aforementioned movable piece 530 can be outwardly convex in the direction D3 to form a boss, which can be regarded as the braking portion 531 of the movable piece 530. The region of the bottom plate 532 outside the periphery of the braking portion 531 can be referred to as a stop portion 538.

[0358] In some examples, the end face of the end of the braking portion 531 away from the bottom plate 532 can be referred to as a braking end, and the user can apply a force to the movable piece 530 by tapping the braking end.

[0359] In some examples, the side of the braking portion 531 close to the accommodating groove 534 can be provided with a socket 502, which can be located above the accommodating groove 534 and can be in communication with the accommodating groove 534. In the process of assembling the connecting frame 540 and the movable piece 530, the clamping portion of the connecting frame 540 can be inserted into the accommodating groove 534 through the socket 502 to contact the abutment face 535-2 of the clamping portion 535.

[0360] In some scenarios, the above structure can also be understood as follows: the braking portion 531 and the bottom plate 532 of the movable piece 530 are connected to the end face of the side wall of the accommodating groove 534 away from the clamping portion 535, and the end of the braking portion 531 away from the bottom plate 532 can extend a certain length in the direction D1 away from the braking portion 531 to form an extension portion 536, which can be located substantially above the accommodating groove 534, and the extension portion 536 can limit the movement space of the clamping portion of the connecting frame 540 accommodated in the accommodating groove 534 in the direction D3 to a certain extent.

[0361] Referring to FIG. 48, to enable the clamping portion 535 to return to the initial position after being pushed by the braking portion 531, the watchband connector 300c can further include an elastic structure 537, which can be fixedly connected with the movable piece 530. During the process in which an external force acts on the braking portion 531 and pushes the movable piece 530 to move in the opposite direction of the direction D3, the elastic structure 537 can be compressed and deformed, or in other words, the length of the elastic structure 537 in the direction D3 can be shortened during the process in which the movable piece 530 moves in the opposite direction of the direction D3. When the external force is removed, the elastic structure 537 gradually recovers the deformation, during which the length of the elastic structure 537 in the direction D3 gradually recovers, and the elastic structure 537 can push the movable piece 530 to move a certain distance in the direction D3, thereby driving the clamping portion 535 to move to the initial position.

[0362] In some examples, the bottom plate 532 of the movable piece 530 can be provided with a receiving groove 539 on the side away from the braking portion 531, and the elastic structure 537 can be accommodated in the receiving groove 539. In one possible scenario, the axis of the receiving groove 539 can be substantially parallel to the direction D3, and the direction of the force generated by the deformation of the elastic structure 537 accommodated in the receiving groove 539 can also be substantially parallel to the direction D3.

[0363] Exemplarily, the depth (dimension in the direction D3) of the receiving groove 539 can be less than the length (dimension in the direction D3) of the elastic structure 537 in the natural state (state not subjected to external force), so that when the movable piece 530 is assembled with the fixed piece 520 and the connector base 510, the elastic structure 537 can be in a compressed state, or in other words, the elastic structure 537 can abut against the groove bottom of the receiving groove 539 and generate a force acting on the movable piece 530 substantially in the direction D3.

[0364] To make the forces acting on different regions of the movable piece 530 by the elastic structure 537 relatively uniform, the elastic structure 537 can be located in the middle region of the movable piece 530, or the elastic structure 537 can be multiple, and the multiple elastic structures 537 can be uniformly distributed on the bottom plate 532 of the movable piece 530.

[0365] In one possible scenario, the number of accommodating grooves 539 on the movable piece 530 is one, and in this case, the accommodating groove 539 can be located at the middle region of the bottom plate 532 of the movable piece 530, and the elastic structure 537 can also be one and accommodated in the accommodating groove 539. In one possible scenario, the number of accommodating grooves 539 on the movable piece 530 can be M (M is an integer, for example, M = 2 or 3, etc.), and accordingly, the number of elastic structures 537 can also be M, and in this case, the M accommodating grooves 539 can be uniformly distributed along the length direction (direction D2) or the width direction (a direction perpendicular to the direction D2) of the movable piece 530, or in other words, the distance spacing between two adjacent accommodating grooves 539, or the spacing between the two accommodating grooves 539 located at the edges and the edges of the movable piece 530 can all be equal. The M elastic structures 537 can be respectively accommodated in the M accommodating grooves 539, and the acting force of the M elastic structures 537 can uniformly act on the movable piece 530.

[0366] Exemplarily, the elastic structure 437 can be a spring, a spring sheet, or the like, which can be deformed under an external force and can restore the deformation after the external force is removed.

[0367] As shown in FIG. 49, the structure of the fixing piece 520 of the watchband connecting piece 300c is shown schematically, and in some scenarios, the fixing piece 520 can be regarded as a part of the aforementioned first mounting piece. As shown in FIG. 50, a BB cross-sectional view of the fixing piece 520 is shown schematically, and as shown in FIG. 51, a schematic view of the combination of the movable piece 530 and the fixing piece 520 is shown.

[0368] In some examples, the fixing piece 520 can include an accommodating cavity, which can be used to accommodate part or all of the movable piece 530. The structure of the accommodating cavity can match the shape of the movable piece 530. In one possible scenario, the movable piece 530 can include the bottom plate 532 and the brake part 531, and in this case, the accommodating cavity of the fixing piece 520 can also be regarded as being composed of two accommodating cavities 521 and 523, wherein the accommodating cavity 521 can be used to accommodate the brake part of the movable piece 530, the accommodating cavity 523 can be used to accommodate the bottom plate 532 of the movable piece 530, and the accommodating cavity 521 and the accommodating cavity 523 are in communication with each other.

[0369] In order to facilitate the user to disassemble and separate the buckle-connected connecting frame 540 and the movable piece 530, in some examples, the part of the fixing piece 520 where the accommodating cavity 521 is provided can be provided with an opening 529 in the thickness direction (the direction D3 in the figure), and the opening 529 can be in communication with the accommodating cavity 521, so that the brake part 531 accommodated in the accommodating cavity 521 can be partially exposed at the position of the aforementioned opening 529, and the user can directly apply an acting force to the brake part 531 of the movable piece 530 from the position of the opening 529. Exemplarily, the brake end of the brake part 531 can be exposed from the aforementioned opening 529.

[0370] Exemplarily, the shape and size of the opening 529 can correspond to those of the accommodating cavity 521. In one possible case, the accommodating cavity 521 can be regarded as being formed by machining a certain depth in the thickness direction of the fixing member 520 from the position of the opening 529 according to the shape and size of the opening 529. In order to reduce the probability of the movable member 530 colliding with the side wall of the accommodating cavity 521 of the fixing member 520 during movement, the inner wall of the accommodating cavity 521 can be arranged in a spaced manner with the side wall of the stop portion 531 of the movable member 530.

[0371] In order to facilitate the installation of the movable member 530 to the fixing member 520, in some examples, the portion of the fixing member 520 that is provided with the accommodating cavity 523 can be provided with an opening 522 in the thickness direction (direction D3 in the figure), which can be in communication with the accommodating cavity 523, so that when assembling the movable member 530 and the fixing member 520, the movable member 530 can be placed into the accommodating cavity of the fixing member 520 from the position of the opening 522.

[0372] Exemplarily, the shape and size of the opening 522 can correspond to those of the accommodating cavity 523. In one possible case, the accommodating cavity 521 can be regarded as being formed by machining a certain depth in the thickness direction of the fixing member 520 from the position of the opening 522 according to the shape and size of the opening 522. In order to reduce the probability of the movable member 530 colliding with the side wall of the accommodating cavity 523 of the fixing member 520 during movement, the inner wall of the accommodating cavity 523 can be arranged in a spaced manner with the side wall of the bottom plate 532 of the movable member 530.

[0373] In one possible implementation, the fixing member 520 can be provided with a through hole in the thickness direction, the port of one end of the through hole can be located on the top surface of the fixing member 520 (i.e., the above-mentioned opening 529), and the port of the other end of the through hole can be located on the bottom surface of the fixing member 520 (i.e., the above-mentioned opening 522). The portion of the through hole close to the top surface of the fixing member can be used to accommodate the stop portion 531, and the portion of the through hole close to the bottom surface of the fixing member can be used to accommodate the bottom plate 532.

[0374] As described above in relation to the movable member 530, the stop portion 531 of the movable member 530 can be located in the middle region of the bottom plate 532, and the stop portion 538 of the bottom plate 532 is located outside the periphery of the stop portion 531. In this case, the projection of the outer contour of the accommodating cavity 521 for accommodating the stop portion 531 on the bottom surface of the fixing member 520 can be located inside the projection of the outer contour of the accommodating cavity 523 on the bottom surface of the fixing member 520. In this way, when the movable member 530 is assembled into the fixing member 520, the stop portion 538 of the bottom plate 532 can function as a baffle to limit the stroke of the movable member 530 along the direction D3.

[0375] Considering the stroke of the movable piece 530 in the fixed piece 520 along the direction D3, one possible case is that the height (dimension along the direction D3) h3 of the accommodating cavity 523 can be greater than the thickness h4 of the bottom plate 532 of the movable piece 530, so that the difference between the height h3 of the accommodating cavity 523 and the thickness h4 of the bottom plate 532 can be understood as the stroke of the movable piece 530 in the fixed piece 520 along the direction D3.

[0376] In some examples, in order to facilitate the insertion of the clamping part of the connecting frame 540 into the socket 502 of the movable piece 530, the sidewall of the fixed piece 520 can be provided with a socket 525, which can be in communication with the aforementioned accommodating cavity 521 and the accommodating cavity 523. In combination with FIGS. 49 and 51, in the case where the movable piece 530 is installed into the fixed piece 520, the socket 502 of the movable piece 530 can be in communication with the socket 525 of the fixed piece 520, so that the clamping part of the connecting frame 540 can extend into the socket 502 from the socket 525 and be clamped with the clamping part 535 of the movable piece 530.

[0377] Referring to FIG. 51, in some examples, in the case where the movable piece 530 is installed into the fixed piece 520, the inclined surface 535-1 of the clamping part 535 can face the socket 525, and the inclined surface 535-1 can play a certain guiding role in the process of inserting the clamping part of the connecting frame 540 into the socket 502.

[0378] Continuing to refer to FIG. 49, in some examples, the fixed piece 520 can further include an accommodating groove 527a and an accommodating groove 527b, which can be respectively provided corresponding to the connecting columns 514a and 514b on the connecting piece base 510 in FIG. 45. In the case where the fixed piece 520 is installed on the connecting piece base 510, the connecting columns 514a and 514b on the connecting piece base 510 can be respectively accommodated in the accommodating grooves 527a and 527b. In other words, the groove walls of the accommodating grooves 527a and 527b can respectively surround the outer periphery of the connecting columns 514a and 514b.

[0379] To enable the fixed part 520 to be fixedly connected with the connecting part base 510, referring to FIG. 50, the bottom surface of the accommodating groove 527a and the bottom surface of the accommodating groove 527b can be respectively provided with a through hole 524a and a through hole 524b, so that, when the fixed part 520 is installed on the connecting part base 510, the through hole 524a at the bottom of the accommodating groove 527a can be in communication with the threaded hole 519a on the connecting column 514a, and a fastener such as a screw can pass through the through hole 524a and the threaded hole 519a at the same time and be engaged with the threads on the inner walls of the through hole 524a and the threaded hole 519a. Similarly, the through hole 524b at the bottom of the accommodating groove 527b can be in communication with the threaded hole 519b on the connecting column 514b, and a fastener such as a screw can pass through the through hole 524b and the threaded hole 519b at the same time and be engaged with the threads on the inner walls of the through hole 524b and the threaded hole 519b. On this basis, the fixed part 520 and the connecting part base 510 can be relatively fixed.

[0380] In a possible implementation, referring to FIG. 50, the accommodating groove 527a and the accommodating groove 527b can be respectively provided near the accommodating cavity of the aforementioned fixed part 520. For example, the accommodating groove 527a can be located at the left side of the sub-accommodating cavity 521, and the accommodating groove 527b can be located at the right side of the sub-accommodating cavity 521.

[0381] Referring to FIGS. 45 and 49, when the accessory 40 is an air bag, the connecting part base 510 can be provided with an air bag connecting pipe 513b, and correspondingly, the fixed part 520 can include a groove body 526, which can be used to accommodate part or all of the air bag connecting pipe 513b. Generally, the air nozzle of an air bag can be approximately in the shape of a circular tube, in which case the outer wall of the air bag connecting pipe 513b can include a curved surface. In order to enable the outer wall of the air bag connecting pipe 513b to better match the inner wall of the groove body 526, the inner wall of the magnet of the groove body 526 can also include a curved surface. In some examples, corresponding to the position of the air bag connecting pipe 513b on the connecting part base 510, the groove body 526 can be provided on the right side of the accommodating cavity of the fixed part 520.

[0382] Referring to FIG. 51, after the fixed part 520 and the movable part 530 are assembled with each other, the brake part 531 of the movable part 530 can be accommodated in the accommodating cavity 521 of the fixed part 520, and the end face of the brake part 531 can be exposed from the position of the opening 529 on the top surface of the fixed part 520, so as to facilitate the user to complete the disassembly of the accessory and the watchband 200 by operating the brake part 531.

[0383] Referring to FIG. 52, the fixing member 520 with the movable member 530 installed thereon can be capped on the connecting member base 510, or in other words, the fixing member 520 with the movable member 530 installed thereon can be inverted on the connecting member base 510. In order to accommodate the fastener, in some examples, the fixing member 520 can be provided with accommodation grooves 528a and 528b on the other side opposite to the bottoms of the accommodation grooves 527a and 527b, so that, when the screw is tightened, the screw cap of the screw can be accommodated in the accommodation groove 528a or 528b, and the screw shank can be inserted into the threaded hole 519a or 519b, and the fastener will not protrude from the surface of the watchband connecting member 300c, which is conducive to reducing the probability of scratching or damaging other components during the installation or disassembly process.

[0384] FIGS. 53 and 54 are structural schematic diagrams of the connecting frame 540 of the watchband connecting member 300c. In some scenarios, the connecting frame 540 can be regarded as part of the aforementioned second mounting member.

[0385] In some examples, the connecting frame 540 can include a clamping portion 549, which can cooperate with the clamping portion 535 of the movable member 530 in the aforementioned first mounting member to achieve detachable connection of the connecting frame 540 and the movable member 530.

[0386] Exemplarily, the connecting frame 540 can include a main body portion 541 and a connecting rod 543 extending out of the main body portion 541, and part or all of the connecting rod 543 can be regarded as the aforementioned clamping portion 549. In one possible scenario, the connecting rod 543 is parallel to the direction D2 in the axial direction, and the two ends of the connecting rod 543 can be fixedly connected with the main body portion 541 through connecting columns 547a and 547b. The aforementioned clamping portion 549 is located in the middle portion of the connecting rod 543, or in other words, the clamping portion 549 is located between the two end portions of the connecting rod 543.

[0387] The connecting rod 543 can be a round rod, or in other words, the outer wall of the connecting rod 543 can be a smooth curved surface, or in other words, the clamping portion 549 of the connecting rod 543 can include a smooth curved surface, which is conducive to the insertion of the connecting rod 543 into the socket 502.

[0388] In some examples, the connecting frame 540 can be fixedly connected with the accessory 40, and exemplarily, the main body portion 541 of the connecting frame 540 can be used to fixedly connect with the accessory 40.

[0389] Referring to FIG. 54, as one possible implementation, the main body portion 541 of the connecting frame 540 can include a sub-connecting portion 542a and a sub-connecting portion 542b, which are substantially plate-shaped, fixedly connected at their left and right ends respectively, and spaced apart from each other at their middle portions. In other words, the oppositely arranged sub-connecting portion 542a and the sub-connecting portion 542b can form a socket 545 therebetween, which can be used to accommodate a portion of the accessory 40 and to achieve the connection between the connecting frame 540 and the accessory 40.

[0390] In some examples, the connecting rod 543 of the connecting frame 540 can be fixedly connected with the sub-connecting portion 542a or the sub-connecting portion 542b via the connecting post 547a and the connecting post 547b.

[0391] In some examples, the sub-connecting portion 542a and the sub-connecting portion 542b can have one or more through holes in their thickness direction, which can cooperate with through holes on the portion of the accessory 40 extending into the socket 545 to achieve the fixed connection between the accessory 40 and the connecting frame 540.

[0392] For example, in FIG. 54, the sub-connecting portion 542a can have a connecting hole 544a and a connecting hole 544b in its thickness direction, which can be distributed along the length direction (direction D2) of the sub-connecting portion 542a. The sub-connecting portion 542b can have a connecting hole 546a and a connecting hole 546b in its thickness direction, which can be distributed along the length direction (direction D2) of the sub-connecting portion 542b. One possible case is that the connecting hole 544a and the connecting hole 546a are arranged correspondingly, and the connecting hole 544b and the connecting hole 546b are arranged correspondingly, or in other words, the connecting hole 544a and the connecting hole 546a are coaxially arranged, and the connecting hole 544b and the connecting hole 546b are coaxially arranged.

[0393] Taking the airbag shown in FIG. 4 as an example, the connecting plate 44 of the accessory 40 can have two through holes 45, which can be positioned correspondingly to the connecting hole 544a and the connecting hole 546a and the connecting hole 544b and the connecting hole 546b respectively, and the inner walls of these connecting holes can be provided with internal threads. By means of fasteners such as screws, when the screws are screwed into the through holes 45 on the connecting plate 44 and the connecting hole 544a and the connecting hole 546a and the connecting hole 544b and the connecting hole 546b on the connecting frame 540 at the same time, the accessory 40 can be connected with the watchband connecting piece 300c.

[0394] In the case that the accessory 40 is an airbag, the accessory 40 also has an air nozzle 43 in the vicinity of the connecting plate 44. In some scenarios, the air nozzle 43 is substantially cylindrical. In order to enable the air nozzle 43 to be stably mounted on the connecting frame 540, in some examples, the main body portion 541 of the connecting frame 540 can be provided with a through hole 548 in the width direction, and the shape and size of the through hole 548 can match the shape and size of the air nozzle 43 of the airbag. During assembly of the air nozzle 43 and the connecting frame 540, the air nozzle 43 can be inserted into the through hole 548. In one possible scenario, part of the air nozzle 43 can pass through the through hole 548.

[0395] The positions of the socket 545 and the through hole 548 on the connecting frame 540 can correspond to the positions of the connecting plate 44 and the air nozzle 43 of the accessory 40. In one possible scenario, the connecting plate 44 and the air nozzle 43 are spaced apart, in which case the socket 545 and the through hole 548 on the connecting frame 540 can also be spaced apart, or in other words, the socket 545 and the through hole 548 on the connecting frame 540 can not be in communication with each other. In another possible scenario, the connecting plate 44 and the air nozzle 43 are adjacent, in which case the socket 545 and the through hole 548 on the connecting frame 540 can be in communication with each other.

[0396] The schematic diagram 57-1, the schematic diagram 57-2, and the schematic diagram 57-3 in FIG. 57 generally show the process of detaching the accessory 40 from the watchband connecting piece 300c.

[0397] In the schematic diagram 57-1, the clamping portion 549 on the connecting frame 540 is buckled to the clamping portion 535 on the movable piece 430, and the surface of the clamping portion 549 and the abutting surface 535-2 of the clamping portion 535 abut against each other, and the friction between the two abutting surfaces can reduce the mutual separation of the connecting frame 540 and the movable piece 530. In addition, when the connecting frame 540 and the movable piece 530 are buckled, the elastic structure 537 is in a compressed state, and the elastic structure 537 has a pressure acting on the movable piece 530, and the direction of the pressure can be along the direction D3 in the drawing, and the pressure can limit the clamping portion 549 from sliding out of the accommodating groove 534 of the movable piece 530. In general, the pressure of the elastic structure 537 and the friction between the clamping portion 549 and the clamping portion 535 can relatively stably connect the connecting frame 540 and the movable piece 530.

[0398] In response to the action of the external force F1 acting on the brake portion 531, the movable member 530 moves in the opposite direction of the direction D3, and the elastic structural member 537 accommodated in the accommodating groove 539 is further compressed under the action of the external force, and the length is shortened until the clamping portion 535 of the movable member 530 is separated from the clamping portion 549 of the connecting frame 540, and the movable member 530 and the connecting frame 540 are in the unlocked state.

[0399] In the case where the movable member 530 and the connecting frame 540 are in the unlocked state, in response to the action of the external force F2 acting on the accessory 40 or the connecting frame 540, the connecting frame 540 can be pulled out of the socket 502.

[0400] In the process of assembling the accessory 40 to the watchband connecting piece 300c, the connecting frame 540 can be inserted into the socket 502 in the opposite direction of the direction D1 shown in FIG. 57, so that the connecting frame 540 is buckled with the movable member 530. In this process, the surface of the clamping portion 549 of the connecting frame 540 and the inclined surface 535-1 of the clamping portion 535 of the movable member 530 are in contact with each other, and the clamping portion 549 can be inserted into the socket 502 along the inclined surface 535-1 and accommodated in the accommodating groove 534. In this process, the elastic structural member 537 accommodated in the accommodating groove 539 is in a compressed state. When the clamping portion 549 is accommodated in the accommodating groove 534, the elastic structural member 537 in the accommodating groove 539 recovers the deformation, and the side wall of the accommodating groove 534 (including the abutting surface 535-2) abuts against the clamping portion 549 of the connecting frame 540, and the contact surfaces of the two generate a pushing force acting on the clamping portion 549, which can limit the clamping portion 549 from sliding out of the accommodating groove 543, and the stop portion 538 can limit the movement of the clamping portion 549 of the connecting frame 540 in the direction D1. In other words, in this state, the clamping portion 535 of the movable member 530 and the clamping portion 549 of the connecting frame 540 are locked, and the accessory 40 and the watchband connecting piece 300c are stably connected.

[0401] The above-mentioned structure for buckling connection between the first mounting member and the second mounting member is only exemplary, and the first mounting member and the second mounting member can also be buckled in other ways.

[0402] For example, the aforementioned movable member 330 can be provided with a notch similar to the notch 341-1 on the aforementioned connecting frame 340, and correspondingly, the connecting frame 340 can be provided with a protruding structure corresponding to the clamping portion 335 on the movable member 330. In the case where the protruding structure of the connecting frame 340 is accommodated in the notch of the movable member 330, the first mounting member and the second mounting member can be buckled; in the case where the protruding structure of the connecting frame 340 is withdrawn from the notch of the movable member 330, the first mounting member and the second mounting member can be in the unlocked state.

[0403] For example, the movable member 530 can include a rod-like structure similar to the connecting rod 543 on the connecting frame 540, and the connecting frame 540 can be provided with a groove-like structure similar to the accommodating groove 534 on the movable member 530. When the rod-like structure of the movable member 530 is accommodated in the groove-like structure of the connecting frame 540, the first mounting member and the second mounting member can be in a buckled connection; when the rod-like structure of the movable member 530 is withdrawn from the groove-like structure of the connecting frame 540, the first mounting member and the second mounting member can be in an unlocked state.

[0404] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
