Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wearable equipment, especially a watchband adjusting mechanism and intelligent wearable equipment. BACKGROUND

[0002] Wearable devices are intelligent electronic devices that can be directly worn on the human body, continuously monitor, record and analyze physiological data (such as heart rate, blood oxygen, sleep quality, etc.), behavioral activities (such as steps, movement trajectory, posture state, etc.) or environmental information (such as temperature, humidity, light intensity, etc.), and realize specific functions (such as health warning, exercise guidance, information reminder, etc.) through data interaction. The core feature is the deep integration of wearability (human body adaptability) and intelligence (data collection and processing).

[0015] As an optional embodiment, the first adjusting assembly and the second adjusting assembly are both arranged as magnets, and the same side magnetic poles of the first adjusting assembly and the second adjusting assembly interact with each other.

[0016] The third adjusting assembly and the fourth adjusting assembly are both arranged as magnets, and the same side magnetic poles of the third adjusting assembly and the fourth adjusting assembly interact with each other.

[0017] As an optional embodiment, an adjusting groove is formed at one end of the first connecting component, and the first adjusting assembly is arranged in the adjusting groove.

[0018] One end of the second connecting component provided with the second adjusting assembly is arranged in the adjusting groove in a telescopic manner through the slot opening of the adjusting groove.

[0019] As an optional embodiment, a limiting groove is further formed in the second connecting component, the limiting groove is at least partially arranged in the adjusting groove, and a first limiting wall is formed in the adjusting groove towards the slot opening of the adjusting groove, and the second adjusting assembly is arranged in the first limiting wall.

[0020] The first connecting component is provided with a second limiting wall in the adjusting groove, the second limiting wall and the first limiting wall are oppositely arranged, the first limiting wall is located between the second limiting wall and the notch of the adjusting groove, and the first adjusting assembly is arranged on the first limiting wall.

[0021] As an optional implementation, the first connecting component comprises:

[0022] A component body, the adjusting groove is arranged in the component body, and the component body is provided with a mounting opening communicating with the adjusting groove on the side adjacent to the notch of the adjusting groove;

This self-adaptive adjusting mechanism allows the user to realize the dynamic optimization of wearing tightness without manual repeated adjustment of the watchband size in different scenes (such as daily wearing, sports monitoring, medical detection, etc.). For example, in daily activities, the first connecting component and the second connecting component are under the centrifugal force generated by the weight of the device body or the user's arm swing, overcome the first acting force to automatically adjust to the state of mutual separation, so that the watchband can be worn more loosely on the user's limbs, and the comfort is improved. When high-precision data acquisition or operation stability is required, the user can make the watchband adjusting mechanism tend to be stable (such as lifting the arm, stopping the arm swing, etc.) to make the first adjusting assembly and the second adjusting assembly lose the effect of external force, so that they are automatically reset to the state of mutual approach, and the watchband can be automatically tightened to fit the skin, thereby significantly improving the flexibility and adaptability of wearing, and reducing the compression or loose problem caused by size mismatch.

[0031] The watchband adjusting mechanism realizes the automatic adjustment of wearing tightness through mechanical structure, significantly simplifies the operation process of watchband size adjustment, and the user does not need to repeatedly adjust the watchband in the wearing or replacement scene, but only needs to trigger the adjusting mechanism through natural activity or preset mode, so that the wearing state can be quickly switched, which not only reduces the use cost (such as time cost, learning cost) of the user, but also reduces the risk of device damage caused by improper manual adjustment, and prolongs the service life of the watchband.

DETAILED DESCRIPTION

[0040] In order to make the technical problems solved by the utility model, the technical scheme adopted and the technical effects reached more clear, the technical scheme of the utility model embodiment is further described in detail below, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of the utility model protection.

[0041] In the description of the utility model, unless another explicit provision and limitation, the term "connection" "connect" "fixed" should be broad sense understanding, for example, can be fixed connection, can be detachable connection, or be integrated;Can be mechanical connection, can be electrical connection;Can be directly connected, can be indirectly connected through the intermediate medium, can be the communication of two elements or the interaction relationship of two elements. For the person skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0042] In the utility model, unless another explicit provision and limitation, the first feature is "on" or "below" the second feature can include the first and second features direct contact, can include the first and second features not direct contact but contact through another feature between them. Moreover, the first feature is "on", "above" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than the second feature. The first feature is "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than the second feature.

[0043] As is known from the background art, wearable devices are intelligent electronic devices that can be directly worn on the human body, continuously monitor, record and analyze physiological data (such as heart rate, blood oxygen, sleep quality, etc.), behavioral activities (such as steps, movement trajectory, posture state, etc.) or environmental information (such as temperature, humidity, light intensity, etc.) of the human body, and realize specific functions (such as health warning, exercise guidance, information reminder, etc.) through data interaction. The core feature is the deep integration of wearability (human body adaptability) and intelligence (data acquisition and processing).

[0044] However, the mainstream wearable devices on the market generally adopt a fixed design of a certain size for the wearing assembly, that is, through the structures of pre-set buckles, watchband holes, elastic bands, etc., the device body is fixed on the user's limbs (such as wrist, arm, ankle, etc.). Although this design meets the basic wearing needs to some extent, in actual use, the user's need for tightness of the wearing assembly is significantly different in different scenarios, making it difficult to effectively balance the wearing comfort and the use convenience.

[0045] Specifically, in the normal wearing state, the user tends to increase the size of the wearing assembly to avoid the device being tightly pressed on the limbs, thereby improving the wearing comfort. For example, in the daily standing with arms down or light exercise scenarios, the user may pay more attention to the looseness of the wearing to reduce the feeling of being bound by long-term wearing. However, when the user needs to perform health detection (such as heart rate monitoring, blood oxygen detection, etc.) through the wearable device or perform other related operations (such as touch screen, press key, etc.) through the device body, the user hopes that the device body can closely fit the skin to improve the detection accuracy or operation stability. For example, in health detection, the closely fitted device can reduce signal interference and improve the reliability of the detection result; when the user performs other related operations through the device body, the device body closely fitted to the skin can reduce the shaking during the related operation, and higher wearing stability provides the user with a better operation experience. The wearing assembly design of a certain size requires the user to repeatedly adjust in different scenarios, which not only increases the user's use cost, but also may cause the device to be loose or too tight due to improper adjustment, affecting the wearing comfort and the use experience.

[0046] Therefore, the present embodiment provides a watchband adjusting mechanism, which achieves dynamic adjustment of the tightness of the watchband by setting a first adjusting assembly and a second adjusting assembly between the first connecting component and the second connecting component which can move relative to each other, so that the watchband can optimize the wearing fit of the device body according to the user's body movement state and the change of external force without manual intervention of the user, thereby solving a series of technical problems such as the difficulty in balancing the wearing comfort and the functional stability of the wearable device, and the large adjustment cost and difficulty of the user.

[0047] Please refer to the drawings in the description Figures 1-6 The watchband adjusting mechanism comprises a first connecting component 10 and a second connecting component 20. The first connecting component 10 is provided with a first adjusting assembly 11. The first connecting component 10 serves as a fixed end of the watchband adjusting mechanism. In addition to providing a mounting position and support for the first adjusting assembly 11 to ensure that the first adjusting assembly 11 can normally play a regulating function, the first connecting component 10 also serves as a connecting hub of one end of the watchband 40 and the device body in the actual application scenario of the wearable device (smart wearable device), and can also be used to connect the other band of the watchband 40.

[0048] In some optional embodiments, the first connecting component 10 can be designed as a block or plate structure with a certain thickness and strength to ensure the stability of the connection between the watchband 40 or the watchband 40 and the device body, for example, made of metal materials (such as stainless steel, titanium alloy). Thus, the watchband 40 is provided with a stable fixing point, so that it can cooperate with the second connecting component to bear the weight of the device body (such as the watch body) and various external forces generated in daily use in the actual use scenario, and ensure that the connection between the watchband 40 and the device body is firm and reliable.

[0049] In the above embodiment, the second connecting component 20 is movably connected with the first connecting component 10, and the second connecting component 20 is configured to reciprocate between positions close to and away from the first connecting component 10. The second connecting component 20 is a movable end of the watchband adjusting mechanism which cooperates with the first connecting component 10 to achieve length adjustment of the watchband 40. In the actual application scenario of the wearable device, the second connecting component 20 can serve as a connecting hub between the first connecting component 10 and the watchband 40, and can also be used to connect one of the bands of the watchband 40. Through the cooperation with the first connecting component 10, the second connecting component 20 changes the distance between the device body and the watchband 40 or the distance between two adjacent bands by its reciprocating movement, so that the length of the watchband 40 is effectively adjusted to adapt to the user's demand for the tightness of the watchband 40 in different use scenarios.

[0050] It can be understood that, in order to be able to achieve a movable connection with the first connecting component 10, the second connecting component 20 is usually designed to be in a shape that is adapted to the first connecting component 10, and the connection between the two can be but is not limited to a sliding rail and sliding block structure, a sliding groove and sliding block structure, etc. Taking the sliding rail and sliding block structure as an example, one of the first connecting component 10 and the second connecting component 20 is provided with a sliding rail, and the other is provided with a sliding block that is matched with the sliding rail structure, and the sliding block is slidably arranged on the sliding rail, so that the second connecting component 20 can be moved between the positions close to and away from the first connecting component 10 through the sliding structure of the sliding block and the sliding rail.

[0051] Further, the second connecting component 20 is provided with a second adjusting assembly 21, and the second adjusting assembly 21 and the first adjusting assembly 11 are configured to apply a first force F1 to each other to drive the second connecting component 20 to approach the first connecting component 10, and the first force F1 can be but is not limited to an elastic force, a magnetic force, etc.

[0052] In the actual application scene of the watchband adjusting mechanism, it can be understood from the above that the first connecting component 10 and the second connecting component 20 need to cooperate to bear the weight of the device main body (such as the watch main body) and various external forces generated in daily use, and the external force will be transmitted between the first connecting component 10 and the second connecting component 20, and will make the two move in the direction of moving away from each other. That is, the interaction force (for the sake of convenience, hereinafter referred to as the use external force F4) between the first connecting component 10 and the second connecting component 20 in the use process is opposite to the direction of the first force F1 generated by the interaction between the first adjusting assembly 11 and the second adjusting assembly 21, and the relative position of the second connecting component 20 and the first connecting component 10 will be adjusted according to the size relationship between the use external force F4 and the first force F1.

[0053] Exemplarily, when the use external force F4 received by the first connecting component 10 and the second connecting component 20 is greater than the first acting force Fl (such as when the arm is lowered and the watchband adjustment mechanism receives a greater weight of the device body 30, when walking and swinging the arm, etc.), the second connecting component 20 will move away from the first connecting component 10, and the second adjustment assembly 21 will move towards the first adjustment assembly 11, thereby increasing the distance between the device body 30 and the watchband 40 or between the bands, and improving the wearing comfort of the user; and when the use external force F4 received by the first connecting component 10 and the second connecting component 20 is less than the first acting force Fl (such as in a stationary state, or when the arm is raised and the watchband adjustment mechanism receives a smaller weight of the device body 30, etc.), the first adjustment assembly 11 and the second adjustment assembly 21 will move in the direction of the reset under the action of the first acting force Fl, and the first connecting component 10 and the second connecting component 20 will also move towards each other, thereby reducing the distance between the device body 30 and the watchband 40 or between the bands, tightening the watchband 40, and finally enabling the device body 30 to be closely attached to the surface of the user's skin.

[0054] That is, the watchband adjustment mechanism can adaptively adjust according to the change of the use external force F4 in different use scenarios of the user (such as daily wear, exercise, sleep, etc.), and the first connecting component 10 (and the first adjustment assembly 11) and the second connecting component 20 (and the second adjustment assembly 21) together complete the dynamic adjustment function of the watchband adjustment mechanism for the tightness of the watchband 40, thereby meeting the user's demand for comfort of the watchband 40 in different use scenarios.

[0055] It is worth mentioning that in some embodiments, the size of the first acting force Fl generated between the first adjustment assembly 11 and the second adjustment assembly 21 changes with the distance between the first adjustment assembly 11 and the second adjustment assembly 21, such as being set to gradually increase when the distance between the first adjustment assembly 11 and the second adjustment assembly 21 gradually decreases. In this way, when the use external force F4 received by the first connecting component 10 and the second connecting component 20 is greater than the first acting force Fl in a certain range, the use external force F4 may be less than the first acting force Fl at a certain distance between the first adjustment assembly 11 and the second adjustment assembly 21, so that the distance between the first connecting component 10 and the second connecting component 20 can reach a state of dynamic balance within a certain range, and the distance between them will fluctuate within a certain range, thereby achieving the corresponding wearing effect of the tightness of the watchband 40.

[0056] It can be understood that the first adjusting component 11 and the second adjusting component 21 can be but not limited to a spring assembly (including but not limited to a tension spring, a compression spring, a torsion spring, an air spring, etc.), the first adjusting component 11 and the second adjusting component 21 form opposite ends of the spring assembly respectively, and are fixed to the first connecting component 10 and the second connecting component 20 respectively, so that the spring assembly can generate an elastic first force F1 on the first connecting component 10 and the second connecting component 20, and the second connecting component 20 has a tendency to approach the first connecting component 10; an elastic rubber block, similar in structure to the above-mentioned spring assembly, the first adjusting component 11 and the second adjusting component 21 form opposite ends of the elastic rubber block respectively, and the second connecting component 20 has a tendency to approach the first connecting component 10 by connecting the first connecting component 10 and the second connecting component 20 through the elastic rubber block respectively; a magnetic repulsion device, the first adjusting component 11 and the second adjusting component 21 are respectively provided as two magnetic bodies with the same magnetic pole, so that the magnetic repulsion (the first force F1) is generated between them, and the second connecting component 20 has a tendency to approach the first connecting component 10.

[0057] In summary, the watchband adjusting mechanism sets the first adjusting component 11 containing the first connecting component 10 and the second connecting component 20 containing the second adjusting component 21, and uses the first force applied by the two to make the second connecting component 20 reciprocate between the positions close to and away from the first connecting component 10 according to the user's needs. This adaptive adjustment mechanism allows the user to dynamically optimize the wearing tightness without manually adjusting the size of the watchband 40 repeatedly in different scenarios (such as daily wear, sports monitoring, medical detection, etc.). For example, in daily activities, the first connecting component 10 and the second connecting component 20 overcome the first force to automatically adjust to a state of moving away from each other under the action of the centrifugal force generated by the weight of the device body 30 or the user's arm swing, so that the watchband 40 can be worn more loosely on the user's limbs, improving comfort; when high-precision data acquisition or operation stability is required, the user can make the watchband adjusting mechanism tend to be stable (such as lifting the arm, stopping the arm swing, etc.) to make the first adjusting component 11 and the second adjusting component 21 lose the effect of external force, so that they automatically reset to a state of approaching each other, and the watchband 40 can automatically tighten to fit the skin, thereby significantly improving the flexibility and adaptability of wearing, and reducing the problem of compression or looseness caused by size mismatch.

[0058] Enhancing the fit of the watchband 40 with the limb, improving data acquisition accuracy and operation stability

[0059] The second connecting component 20 is configured to allow movement relative to the first connecting component 10 along the longitudinal direction of the watchband adjustment mechanism, in combination with the transversely arranged plurality of adjustment members, to form a multi-dimensional adjustment capability. This design enables precise size adjustment of the watchband 40 in both longitudinal and transverse dimensions, thereby ensuring close fitting of the watchband 40 to the user's limbs (such as the wrist). For example, in a health monitoring scenario, close contact of the watchband 40 with the skin can significantly reduce signal interference and improve the accuracy of physiological data such as heart rate and blood oxygen; in motion monitoring or touch operation, the stability of the watchband 40 can avoid errors or operation failures caused by looseness, further improving the user experience.

[0060] Furthermore, the watchband adjustment mechanism automatically adjusts the wearing tightness through a mechanical structure, significantly simplifying the operation process of size adjustment of the watchband 40. The user does not need to repeatedly adjust the watchband 40 in the wearing or replacement scenario, but only needs to trigger the adjustment mechanism through natural activity or a preset mode to achieve rapid switching of the wearing state. This not only reduces the user's use cost (such as time cost and learning cost), but also reduces the risk of device damage caused by improper manual adjustment, prolonging the service life of the watchband 40.

[0061] In addition, the watchband adjustment mechanism realizes adjustment control of the first connecting component 10 and the second connecting component 20 through the simple first adjustment assembly 11 and the second adjustment assembly 21. This structure not only enables adaptive adjustment of the length of the watchband 40 in different use scenarios, balances the wearing comfort and operation experience of the user, but also has a simple and compact structure, making the overall watchband 40 small in size and light in weight, convenient for the user to wear for a long time without a sense of burden, and improving the user's use experience.

[0062] Please further refer to the drawings in the description Figures 1-6 In an embodiment, for ease of understanding, the embodiment takes the second connecting component 20 as an example, which is configured to allow movement relative to the first connecting component 10 along the longitudinal direction of the watchband adjustment mechanism.

[0063] In the above embodiment, the first adjustment assembly 11 includes a plurality of first adjustment members 111, and the second adjustment assembly 21 includes a plurality of second adjustment members 211. The plurality of first adjustment members 111 and the plurality of second adjustment members 211 are arranged along the transverse direction of the watchband adjustment mechanism.

[0064] It should be noted that the longitudinal direction described in the present embodiment refers to the direction parallel to the movement direction of the second connecting component 20 relative to the first connecting component 10, and the transverse direction refers to the direction perpendicular to the movement direction of the second connecting component 20 relative to the first connecting component 10 on the watchband adjustment mechanism. For specific reference, please refer to the "longitudinal direction" and "transverse direction" indicated by the arrows in the drawings. Figures 1-2 ​

[0065] The first adjusting assembly 11 is provided with a plurality of first adjusting members 111, and the second adjusting assembly 21 is provided with a plurality of second adjusting members 211, and the arrangement direction of the first adjusting members 111 and the second adjusting members 211 is perpendicular to the movement direction of the second connecting component 20 relative to the first connecting component 10, which can significantly improve the stability of the second connecting component 20 when subjected to the first force F1. Compared with the mode in which the first adjusting assembly 11 and the second adjusting assembly 21 are respectively provided with only one adjusting member, the present scheme adopts the mode of multi-point support to disperse the load, so that the plurality of first adjusting members 111 and the plurality of second adjusting members 211 form distributed support, and the first force F1 generated between the first adjusting members 111 and the second adjusting members 211 can be parallel to the longitudinal direction of the watchband adjusting mechanism (the movement direction of the second connecting component 20), so that the force is dispersed to a larger area, the local stress is reduced, and the lateral force caused by movement is avoided to cause the second connecting component 20 to deviate.

[0066] In addition, the first adjusting assembly 11 and the second adjusting assembly 21 can also improve the reliability of the watchband adjusting mechanism through the mode of multi-point interaction cooperation. In actual use scenarios, if a first adjusting member 111 or a second adjusting member 211 fails, other adjusting members can still continuously provide the first force F1 to the second connecting component 20, so that the overall structure of the watchband 40 does not fail and falls off and the like.

[0067] Of course, in the above embodiment in which the first adjusting assembly 11 includes a plurality of first adjusting members 111 and the second adjusting assembly 21 includes a plurality of second adjusting members 211, the first adjusting assembly 11 and the second adjusting assembly 21 can also be provided in an integrated structure and respectively extend along the transverse direction of the watchband adjusting mechanism.

[0068] In order to improve the stability of the watchband adjusting mechanism in some use states and reduce the foreign body sensation (which can be caused by the floating of the spacing between the first connecting component 10 and the second connecting component 20) felt by the user in the corresponding use state, please refer to the schematic view of FIG. 8. Figures 3-6 In an embodiment, the first connecting component 10 is further provided with a third adjusting assembly 12, and correspondingly, the second connecting component 20 is further provided with a fourth adjusting assembly 22.

[0069] The third adjusting assembly 12 and the fourth adjusting assembly 22 work together and interact with each other through elasticity, magnetism, etc. to achieve further adjustment and constraint of the length of the watchband 40 in different use states. Specifically, when the second connecting component 20 is in a position close to the first connecting component 10, the fourth adjusting assembly 22 and the third adjusting assembly 12 are configured to apply a second acting force to each other to drive the second connecting component 20 to be close to the first connecting component 10; when the second connecting component 20 is in a position away from the first connecting component 10, the fourth adjusting assembly 22 and the third adjusting assembly 12 are configured to apply a third acting force to each other to drive the second connecting component 20 to be away from the first connecting component 10.

[0070] As can be seen from the above, when the first adjusting assembly 11 and the second adjusting assembly 21 are in a state of relatively far distance (the second connecting component 20 is in a position close to the first connecting component 10), the first acting force F1 generated between the two is small. At this time, in order to ensure the stability of the first connecting component 10 and the second connecting component 20 in the state of being close to each other, the third adjusting assembly 12 and the fourth adjusting assembly 22 are further added, so that the second connecting component 20 can generate the second acting force F2 in the state of being close to the first connecting component 10, and the device body 30 of the wearable device can be stably attached to the user's limbs under the further action of the second acting force F2, thereby providing more accurate and stable use experience for the user in the scene of health detection or related operation. When the first adjusting assembly 11 and the second adjusting assembly 21 are in a state of relatively close distance (the second connecting component 20 is in a position away from the first connecting component 10), the first acting force F1 generated between the two is large. At this time, in order to reduce the relative floating of the first connecting component 10 and the second connecting component 20, and enable the wearable device to be worn on the user's limbs in a relatively loose state to a certain extent, the third adjusting assembly 12 and the fourth adjusting assembly 22 are further added, so that the third acting force F3 generated between the third adjusting assembly 12 and the fourth adjusting assembly 22 can balance the first acting force F1 in the state of the watchband adjusting mechanism, so as to reduce the relative shaking of the second connecting component 20 in the state of daily wearing (such as hanging arms, swinging arms, etc.) of the user, and obtain a more comfortable wearing experience.

[0071] It can be understood that the third adjusting assembly 12 and the fourth adjusting assembly 22 are similar in structure and principle to the first adjusting assembly 11 and the second adjusting assembly 21, and can but are not limited to adopting a spring assembly, an elastic rubber block, a magnetic repulsion device, etc. to provide the corresponding second acting force F2 and the third acting force F3.

[0072] It can be understood that the third adjusting assembly 12 and the fourth adjusting assembly 22 have a critical point in the movement stroke of the second connecting component 20 and the first connecting component 10 in order to realize the switching of the direction of the interaction force, when the second connecting component 20 moves relative to the first connecting component 10 to cross the critical point, the direction of the interaction force of the third adjusting assembly 12 and the fourth adjusting assembly 22 will change. That is, when the second connecting component 20 is in a state of being relatively close to the first connecting component 10, the third adjusting assembly 12 and the fourth adjusting assembly 22 are in the critical point, so that the two interact to provide the second force F2, at this time the second force F2 is greater than the first force F1, so as to compensate for the force received by the second connecting component 20, so that it can be more stable in this use state. When the use external force F4 received by the watchband adjusting mechanism is greater than the sum of the first force F1 and the second force F2, the second connecting component 20 will move away from the first connecting component 10, and in the movement process, the relative position of the third adjusting assembly 12 and the fourth adjusting assembly 22 will also change, so that they cross the above-mentioned critical point and change the second force F2 between them to the third force F3, the sum of the third force F3 and the use external force F4 can be set to be slightly greater than or substantially equal to the first force F1, so that the second connecting component 20 can remain in a state of being relatively far away from the first connecting component 10 in the user's daily use state, to improve the user's wearing comfort.

[0073] For example, in the embodiment where the third adjusting component 12 and the fourth adjusting component 22 are spring components, the relative position of the third adjusting component 12 and the fourth adjusting component 22 (the two ends of the spring component) will change with the relative position of the first connecting component 10 and the second connecting component 20, and the critical point of the third adjusting component 12 and the fourth adjusting component 22 is the relative state of the two, that is, when the third adjusting component 12 is on the first side of the fourth adjusting component 22, the two are within the critical point, and the second force F2 is generated by the interaction between the two, while when the third adjusting component 12 is on the other side of the fourth adjusting component 22, the two are outside the critical point, and the third force F3 is generated by the interaction between the two; similarly, in the embodiment where the third adjusting component 12 and the fourth adjusting component 22 are elastic rubber blocks, the relative position of the third adjusting component 12 and the fourth adjusting component 22 (the two ends of the elastic rubber block) will change with the relative position of the first connecting component 10 and the second connecting component 20, and the critical point of the third adjusting component 12 and the fourth adjusting component 22 is the relative state of the two (the center lines of the two are in a state of substantially coinciding), that is, when the third adjusting component 12 is on the first side of the fourth adjusting component 22, the two are within the critical point, and the second force F2 is generated by the interaction between the two, while when the third adjusting component 12 is on the other side of the fourth adjusting component 22, the two are outside the critical point, and the third force F3 is generated by the interaction between the two; and in the embodiment where the third adjusting component 12 and the fourth adjusting component 22 are magnetic repulsion devices, the relative position of the third adjusting component 12 and the fourth adjusting component 22 (the two magnetic bodies) will change with the relative position of the first connecting component 10 and the second connecting component 20, and the critical point of the third adjusting component 12 and the fourth adjusting component 22 is the relative state of the two, that is, when the third adjusting component 12 is on the first side of the fourth adjusting component 22, the two are within the critical point, and the second force F2 is generated by the interaction between the two, while when the third adjusting component 12 is on the other side of the fourth adjusting component 22, the two are outside the critical point, and the third force F3 is generated by the interaction between the two.

[0074] By adopting the above-mentioned embodiments, the watchband adjusting mechanism can make the second connecting component 20 more stably in the corresponding position state according to the use state and situation of the user, reduce the shaking and deviation of the second connecting component 20 in the corresponding position state, and increase the damping feeling in the state switching process, thereby improving the user experience and wearing comfort.

[0075] Please refer to the drawings in the specification Figures 3-6, continue to take the above-mentioned second connecting component 20 is configured to allow the movement of the first connecting component 10 along the longitudinal direction of the watchband adjustment mechanism as an example.

[0076] In this embodiment, the third adjustment assembly 12 includes a third adjustment piece 121, and the fourth adjustment assembly 22 includes a fourth adjustment piece 221. Here, the positions and numbers of the third adjustment piece 121 and the fourth adjustment piece 221 are not strictly limited and required, as long as the third adjustment piece 121 and the fourth adjustment piece 221 can generate the action force in the correct direction in the corresponding state to make the second connecting component 20 have the corresponding movement trend.

[0077] Specifically, the third adjustment piece 121 and the fourth adjustment piece 221 are arranged along the longitudinal direction of the watchband adjustment mechanism, and the sizes of the third adjustment piece 121 and the fourth adjustment piece 221 in the longitudinal direction determine the sizes of the action forces generated by the third adjustment piece 121 and the fourth adjustment piece 221 in different critical states and the action force of the second connecting component 20 in different position states. Generally, the lengths of the third adjustment piece 121 and the fourth adjustment piece 221 extending in the longitudinal direction of the watchband adjustment mechanism are in the range of 1 / 3-2 / 3 of the movement stroke of the second connecting component 20 relative to the first connecting component 10. This range can reduce the variation range of the action force provided by the third adjustment piece 121 and the fourth adjustment piece 221 for the second connecting component 20 to a certain extent, so that the second connecting component 20 is in a suspended state in most of the stroke range, and only when it is close to or far away from the first connecting component 10, the corresponding second action force F2 or third action force F3 is applied to it.

[0078] In addition, in order to avoid physical interference between the third adjustment assembly 12 and the fourth adjustment assembly 22 during the movement of the second connecting component 20, the projections of the third adjustment piece 121 and the fourth adjustment piece 221 are arranged in the longitudinal direction of the watchband adjustment mechanism. That is, during the reciprocating movement of the second connecting component 20 in the longitudinal direction, the third adjustment piece 121 and the fourth adjustment piece 221 do not collide or interfere with each other, ensuring that they can be smoothly switched in and out of the critical range.

[0079] In an embodiment, in order to ensure the structural stability of the second connecting component 20, the third adjustment piece 121 and the fourth adjustment piece 221 are both arranged as two, and the two third adjustment pieces 121 and the two fourth adjustment pieces 221 are arranged on both sides of the first connecting component 10 and the second connecting component 20 in the transverse direction, respectively. They are staggered in the longitudinal direction, ensuring that they can affect each other while not interfering with each other in the stroke range of the second connecting component 20, and ensuring that the second connecting component 20 can be simultaneously subjected to the second action force F2 or the third action force F3 to maintain stability.

[0080] In an embodiment, the first adjusting component 11 and the second adjusting component 21 are both provided as magnets, and the magnetic poles on the side where the first adjusting component 11 and the second adjusting component 21 interact are the same, and the third adjusting component 12 and the fourth adjusting component 22 are both provided as magnets, and the magnetic poles on the side where the third adjusting component 12 and the fourth adjusting component 22 interact are the same, so that the first adjusting component 11 and the second adjusting component 21, and the third adjusting component 12 and the fourth adjusting component 22 can both generate magnetic repulsion in corresponding directions according to the positional relationship between the first connecting component 10 and the second connecting component 20, to drive the first connecting component 10 and the second connecting component 20 to remain in a position state that conforms to the current use scenario of the user.

[0081] In this embodiment, the adjusting member in each adjusting component is provided as a magnet, so that any two cooperating adjusting components can achieve the elimination of wear problems that may be caused by the adjusting process through the non-mechanical contact relationship between the magnets, thereby prolonging the service life of the watchband adjusting mechanism. At the same time, the magnetic force generated between the magnets is relatively stable and is not affected by environmental factors such as dust and humidity, so that the wearable device using the watchband adjusting mechanism can provide stable adaptive adjustment function.

[0082] The non-mechanical contact relationship can also avoid the noise generated between the adjusting components during the adjusting process, so that the wearable device is in a silent state during the switching process between different use states, and the user experience is improved.

[0083] In addition, the interaction between the magnets of each adjusting component in this embodiment meets the relevant use requirements, and the first connecting component 10 and the second connecting component 20 do not need to be designed with complex mechanical structures, but only need to be provided with a clamping groove for clamping the corresponding magnet, or the magnet can be directly bonded to the first connecting component 10 and the second connecting component 20. In this way, the design and processing difficulty and cost of the watchband adjusting mechanism are effectively reduced, thereby facilitating the large-scale application of wearable devices.

[0084] It is worth mentioning that in this embodiment, the first force F1, the second force F2, and the third force F3 are generated on the second connecting member 20 by magnetic repulsion. Compared with the method of generating the relevant forces by magnetic attraction, the magnetic repulsion scheme is closer to the physical characteristics of a spring, which allows the second connecting member 20 to have a certain continuous floating ability when subjected to the corresponding force. It will dent when compressed and return to its original shape after the pressure is removed, and it can adapt to different pressures. On the other hand, the magnetic attraction scheme is more inclined to the physical characteristics of a fixed connection (rigid locking). When the second connecting member 20 is close to the first connecting member 10, the magnetic attraction will increase sharply, and when the second connecting member 20 is away from the first connecting member 10, a strong attraction must be overcome to allow the two to separate. For example, if the spacing between the magnets is too small, the attraction may exceed the user's pulling force, making it difficult to open the watch strap 40; if the spacing is too large, the attraction is insufficient, and the watch strap 40 is easy to loosen. It is difficult for the components to achieve a dynamic floating effect, and the switching of the second connecting component 20 according to different user scenarios is more abrupt and sudden. It is estimated that adopting a magnetic repulsion method can further satisfy the user's experience.

[0085] In practical application scenarios, such as Figure 5 As shown, when the fourth adjustment component 22 is on the first side of the third adjustment component 12, the second connecting component 20 is positioned close to the first connecting component 10. At this time, the magnetic repulsion force generated between the third adjustment component 12 and the fourth adjustment component 22 is the second force F2, causing the second connecting component 20 to tend to move towards the first connecting component 10; Figure 6 As shown, when the external force F4 between the second connecting component 20 and the first connecting component 10 is greater than the sum of the first force F1 and the second force F2, the second connecting component 20 will move away from the first connecting component 10, thereby causing the center line of the fourth adjusting component 22 to cross the center line of the third adjusting component 12. The relationship between the two switches from within the critical range to outside the critical range, thereby changing the magnetic repulsion between them into the third force F3. At this time, the sum of the third force F3 and the external force F4 will be slightly greater than or basically equal to the first force F1, so that the second connecting component 20 can remain as stable as possible.

[0086] As an optional implementation method, such as Figures 3-4As shown, the first connecting component 10 has an adjusting slot 13 at one end, and the first adjusting assembly 11 is arranged in the adjusting slot 13. Correspondingly, the second connecting component 20 is provided with the second adjusting assembly 21, and one end of the second adjusting assembly 21 is arranged in the adjusting slot 13 through the slot opening of the adjusting slot 13 in a telescopic manner. The second connecting component 20 is at least partially arranged in the first connecting component 10, which can make the overall structure of the watchband adjusting mechanism more simple and compact. The adjusting slot 13 provides a precise movement track for the second adjusting assembly, and the two do not need to be provided with additional complex transmission mechanisms (such as guide rails and sliding blocks) to realize the adjustment of the length of the watchband 40, ensure the stability of the movement direction, and avoid the deviation or shaking of the second connecting component 20 when moving relative to the first connecting component 10.

[0087] In addition, the adjusting slot 13 also provides sufficient installation space and position for the first adjusting assembly 11, and allows one end of the second connecting component 20 provided with the second adjusting assembly 21 to be arranged therein. In the above embodiment including the third adjusting assembly 12 and the fourth adjusting assembly 22, in order to ensure the stable cooperation relationship between the two, the third adjusting assembly 12 and the fourth adjusting assembly 22 are also arranged in the adjusting slot 13, thereby saving the external space of the watchband adjusting mechanism, making the overall watchband 40 thinner, and avoiding the foreign body sensation caused by the watchband adjusting mechanism to the user's limbs in the wearing state.

[0088] Please continue to refer to the description of the accompanying drawings Figures 3-6In a further embodiment, the second connecting component 20 is further provided with a limiting slot 23, which is at least partially located in the adjusting slot 13, and the limiting slot 23 is provided with a first limiting wall 231 facing the opening of the adjusting slot 13, and the second adjusting assembly 21 is arranged on the first limiting wall 231. Correspondingly, the first connecting component 10 is provided with a second limiting wall 14 located in the adjusting slot 13, and the second limiting wall 14 and the first limiting wall 231 are oppositely arranged, the first limiting wall 231 is located between the second limiting wall 14 and the opening of the adjusting slot 13, and the first adjusting assembly 11 is arranged on the first limiting wall 231. Specifically, when the second connecting component 20 is located close to the first connecting component 10, a space is formed between the first limiting wall 231 and the second limiting wall 14, which allows the second connecting component 20 to move relative to the first connecting component 10. When the second connecting component 20 moves away from the first connecting component 10, the first limiting wall 231 and the second limiting wall 14 move towards each other until they abut against each other, thereby restricting the second connecting component 20 from continuing to extend out of the first connecting component 10. By arranging the first adjusting assembly 11 and the second adjusting assembly 21 on the first limiting wall 231 and the second limiting wall 14 respectively, on the basis of providing the limiting function between the first connecting component 10 and the second connecting component 20 by the first limiting wall 231 and the second limiting wall 14, the first adjusting assembly 11 and the second adjusting assembly 21 are overlapped in the longitudinal projection direction of the watchband adjusting mechanism, so that a more stable first force F1 can be generated between the first adjusting assembly 11 and the second adjusting assembly 21, and the stress on the second connecting component 20 is more uniform and stable.

[0089] In an embodiment, the third adjusting assembly 12 and the fourth adjusting assembly 22 are arranged on the opposite two slot walls of the adjusting slot 13 in the transverse direction and on the opposite two side surfaces of the second connecting component 20 in the transverse direction respectively, so that when the second connecting component 20 moves in the adjusting slot 13, the third adjusting assembly 12 and the fourth adjusting assembly 22 can more easily generate the mutual force, while ensuring the constraint of the adjusting slot 13 on the movement direction of the second connecting component 20, and saving the external space of the watchband adjusting mechanism.

[0090] Based on the above-mentioned embodiment that the first connecting component 10 is provided with the adjusting slot 13 at one end, Figures 3-4As shown, in a further embodiment, the first connecting component 10 comprises a component body 15 and a cover body 16, which in an embodiment can assume the role of the second limiting wall 14 described above. The adjusting groove 13 is formed in the component body 15, and the component body 15 is provided with a mounting opening 151 communicating with the adjusting groove 13 on the side adjacent to the groove opening, and the cover body 16 is arranged on the component body 15 and covers the mounting opening 151. The first connecting component 10 in this embodiment adopts a modular design concept, and the component body 15 is formed with a mounting opening 151 for accommodating the second connecting component 20 and the first adjusting assembly 11 and the third adjusting assembly 12, thereby simplifying the overall assembly process of the watchband adjusting mechanism and reducing the production difficulty of the first connecting component 10 and the overall assembly and maintenance difficulty of the watchband adjusting mechanism.

[0091] By arranging the cover body 16 on the mounting opening 151, the stability of the second connecting component 20 and the series of adjusting assemblies after being assembled in the adjusting groove 13 can be ensured. Under the cooperation of the first limiting wall 231 and the second limiting wall 14, the second connecting component 20 and the related adjusting assemblies cannot be separated from the first connecting component 10 in the adjusting groove 13, so that the overall structural strength of the watchband adjusting mechanism is guaranteed.

[0092] In addition, the cover body 16 covers the mounting opening 151, which can effectively prevent foreign matter such as external impurities and dust from easily entering the adjusting groove 13, thereby reducing the risk of the second connecting component 20 being stuck relative to the first connecting component 10.

[0093] Continuing to the related embodiments of the first connecting component 10 having the adjusting groove 13 formed at one end, in an embodiment, as shown in Figures 3-6 The adjusting groove 13 is provided with a positioning groove 17 at the end away from the groove opening, the positioning groove 17 and the adjusting groove 13 are in communication, and the width of the adjusting groove 13 in the transverse direction is greater than the width dimension of the positioning groove 17 in the transverse direction, so it can also be understood that the positioning groove 17 is recessed on the side away from the groove opening of the adjusting groove 13. Correspondingly, the second connecting component 20 is provided with a positioning block 24 at the end in the adjusting groove 13, which is matched with the structure of the positioning groove 17. When the second connecting component 20 is located close to the first connecting component 10, the positioning block 24 is movably inserted into the positioning groove 17.

[0094] In one embodiment, in order to facilitate the insertion of the positioning block 24 into the positioning groove 17, a transition portion 18 is provided between the positioning groove 17 and the adjustment groove 13. The transition portion 18 forms a guide surface between the adjustment groove 13 and the positioning groove 17 that is inclined from the groove wall of the adjustment groove 13 to the groove wall of the positioning groove 17, so that the positioning block 24 can be guided into the positioning groove 17 by the transition portion 18 during the movement towards the positioning groove 17, thereby avoiding the second connecting portion from getting stuck during the movement towards the first connecting portion.

[0095] The cooperation between the positioning groove 17 and the positioning block 24 can further improve the stability of the second connecting component 20 when it is close to the first connecting component 10, thereby making the device body 30 of the wearable device more stable in the corresponding use state, and improving its detection accuracy or user's operating experience.

[0096] Please refer to the instruction manual attached. Figures 1-2 This embodiment also provides a smart wearable device, which adopts the strap adjustment mechanism provided in any of the above embodiments, and further includes a device body 30 and a strap 40.

[0097] The following describes a specific connection method for the strap adjustment mechanism in the smart wearable device, based on the technical solution provided in the above embodiments:

[0098] I. For example Figures 1-2 As shown, the first connecting component 10 is installed on the device body 30, and the second connecting component 20 is connected to one end of the watch strap 40. In actual application scenarios, the distance between the first connecting component 10 and the second connecting component 20 can change according to the different usage states of the user, so that the distance between the watch strap 40 and the device body 30 can be increased or decreased, thereby adaptively adjusting the size of the wearing space enclosed by the watch strap 40 and the device body 30.

[0099] 2. The watch strap 40 includes a first strap body and a second strap body. Here, the first strap body and the second strap body can also be understood as the first watch bit and the second watch bit. This embodiment does not impose strict limitations or requirements on this. The first connecting part 10 and the second connecting part 20 are respectively connected to the first strap body and the second strap body. In actual use scenarios, the distance between the first connecting part and the second connecting part can change according to the different usage states of the user, so that the distance between the first strap body and the second strap body changes accordingly, thereby adjusting the size of the wearing space.
