Description

Technical Field

[0001] The present application belongs to the technical field of wearable devices, and specifically relates to a tension adjustment device, a connecting belt assembly and a wearable device. Background Art

[0002] With the development of technology and the increase in usage demand, wearable devices are increasingly accepted by consumers, such as smart watches, which provide greater convenience for people's daily communications and health management.

[0003] Wearable devices currently on the market generally have some health monitoring functions, such as heart rate and blood oxygen detection, and blood pressure detection. These monitoring functions require the wearable device to be in a good wearing state, and the connecting belt of the wearable device should not be too loose or too tight. Too loose or too tight may cause the test error to increase. Specifically, taking the blood pressure detection function as an example, the wearable devices currently equipped with the blood pressure detection function generally use the oscillometric method (oscillation method) to collect human blood pressure data. The connecting belt is used as an air bag. The fluctuation of human blood pressure will cause the change of air pressure in the air bag, which will be detected by the sensor in the wearable device. The tightness of the connecting belt can easily have a greater impact on the blood pressure measurement of the detection site, resulting in inaccurate testing. Only when the connecting belt fits well with the arm and there is no obvious constraint can accurate blood pressure data be measured. Therefore, this requires that the connecting belt of the wearable device can adjust the tightness more accurately when worn, to ensure that the connecting belt and the arm can fit accurately without constraint, neither too loose nor too tight, so as to meet the accuracy requirements of blood pressure, heart rate, and blood oxygen detection.

[0004] The traditional way to adjust the tightness of the connecting belt is to adjust the tightness by inserting a pin buckle or a tongue buckle into small holes at different positions on the connecting belt. However, in this way, the tightness can only be adjusted in steps according to the position of the small holes, and the tightness cannot be adjusted accurately. Moreover, after the wearable device is worn, when the tightness needs to be adjusted again, the pin buckle or the tongue buckle needs to be removed from the small hole and then reinserted into another small hole, which is cumbersome and inconvenient to adjust.

[0005] Therefore, existing wearable devices have the disadvantages of poor tightness adjustment accuracy and complicated adjustment operation. Summary of the invention

[0006] The purpose of the embodiments of the present application is to provide a tightness adjustment device, a connecting belt and a wearable device, which can solve the problems in the related art that the tightness adjustment accuracy of wearable devices is poor and the adjustment operation is cumbersome.

[0007] In a first aspect, an embodiment of the present application provides a tension adjustment device for adjusting the wearing length of a first connecting strap and a second connecting strap of a wearable device, comprising: A fixing seat, used to connect with the first connecting belt and the second connecting belt, and the fixing seat is used to slide with at least one of the first connecting belt and the second connecting belt; A clamping member, movably disposed on the fixing seat, the clamping member being used to clamp with the first connecting belt so that the first connecting belt, the second connecting belt and the fixing seat are relatively fixed; A locking member connected to the clamping member, the locking member being used to lock the clamping member so that the clamping member is clamped with the first connecting belt; The operating member is movably arranged on the fixing seat. When the operating member is in a first position, the locking member locks the locking member; when the operating member is in a second position, the locking member unlocks the locking member.

[0008] In a second aspect, an embodiment of the present application further provides a connecting belt assembly, comprising a first connecting belt, a second connecting belt and the above-mentioned tension adjustment device, wherein the first connecting belt and the second connecting belt are both connected to a fixed seat of the tension adjustment device, and at least one of the first connecting belt and the second connecting belt is slidably matched with the fixed seat, and the clamping member of the tension adjustment device can be clamped with the first connecting belt to fix the first connecting belt, the second connecting belt and the fixed seat relatively.

[0009] In a third aspect, an embodiment of the present application also provides a wearable device, comprising a device body and the above-mentioned connecting belt assembly, wherein the second end of the first connecting belt is connected to the first end of the device body, and the second end of the second connecting belt is connected to the second end of the device body.

[0010] In the embodiment of the present application, the locking member can be unlocked by moving the operating member, so that the locking member no longer locks the card member, and the card member can be separated from the first connecting band, so that the first connecting band and the second connecting band can be moved relative to each other, so as to be able to adjust the length of the first connecting band and / or the second connecting band relative to the fixed seat. In this way, the user can infinitely adjust the wearing length of the first connecting band and the second connecting band according to the actual thickness of the arm, so as to accurately adjust the tightness of the connecting band of the wearable device, and the purpose of adjusting the tightness of the connecting band can be achieved by simply moving the operating member, and the operation is simple and convenient.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0015] The following, in combination with the accompanying drawings, describes in detail the tension adjustment device, the connecting belt assembly and the wearable device provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0016] refer to Figure 1-Figure 15 A tightness adjustment device 300 provided in an embodiment of the present application can be used to adjust the wearing length of the first connecting strap 100 and the second connecting strap 200 of the connecting strap assembly, thereby achieving the purpose of adjusting the tightness of the wearable device.

[0017] Among them, the tension adjustment device 300 may include a fixed seat 310, which can be used to connect with the first connecting belt 100 and the second connecting belt 200, and the fixed seat 310 can be used to slide with at least one of the first connecting belt 100 and the second connecting belt 200. For example, in one embodiment, the fixed seat 310 is slidingly connected to the first connecting belt 100, and the fixed seat 310 is fixedly connected to the second connecting belt 200; in another embodiment, the first connecting belt 100 and the second connecting belt 200 are both slidingly connected to the fixed seat 310.

[0018] The tension adjustment device 300 may further include a clamp 320 and a locking member 330. The clamp 320 may be movably disposed on the fixing seat 310, and the clamp 320 may be used to clamp with the first connecting belt 100, so that the first connecting belt 100, the second connecting belt 200 and the fixing seat 310 are relatively fixed, thereby making the tightness of the connecting belt assembly meet the required requirements. The locking member 330 may be connected to the clamp 320, and the locking member 330 may be used to lock the clamp 320, so that the clamp 320 is clamped with the first connecting belt 100, so that the clamp 320 can be kept in the state of being clamped with the first connecting belt 100, thereby preventing the first connecting belt 100 from being moved under force, so as to ensure that the tightness of the connecting belt assembly is kept at the required requirements.

[0019] The tension adjustment device 300 may also include an operating member 340, which is movably disposed on the fixed seat 310. When the operating member 340 is in the first position, the locking member 330 can lock the clamping member 320 so that the clamping member 320 is clamped with the first connecting belt 100; when the operating member 340 is in the second position, the locking member 330 can unlock the clamping member 320 so that the clamping member 320 is no longer clamped with the first connecting belt 100.

[0020] Specifically, the user can apply a force to the operating member 340 so that the operating member 340 moves to the second position. During the movement of the operating member 340 to the second position, the operating member 340 can drive the locking member 330 to move so that the locking member 330 is unlocked, and then the clamping member 320 is no longer locked, so that the clamping member 320 can be separated from the first connecting belt 100. At this time, the first connecting belt 100 can move relative to the fixing seat 310 and the second connecting belt 200. The user can adjust the length of the first connecting belt 100 extending relative to the fixing seat 310 to adjust the tightness of the connecting belt assembly, thereby improving the user experience. When the wearing length of the first connecting belt 100 and the second connecting belt 200 meets the requirements, the user can release the operating member 340, so that the operating member 340 moves to the first position, so that the locking member 330 locks the clamping member 320, and then the clamping member 320 is clamped with the first connecting belt 100, so that the wearing length of the first connecting belt 100 and the second connecting belt 200 is maintained at the required length.

[0021] With such arrangement, the locking member 330 can be unlocked by moving the operating member 340 to the second position, so that the locking member 330 no longer locks the clamping member 320, and the clamping member 320 can be separated from the first connecting band 100, so that the first connecting band 100 and the second connecting band 200 can be moved relative to each other, so as to be able to adjust the length of the first connecting band 100 and / or the second connecting band 200 extending relative to the fixing seat 310. In this way, the user can infinitely adjust the wearing length of the first connecting band 100 or the second connecting band 200 according to the actual thickness of the arm, so as to accurately adjust the tightness of the connecting band of the wearable device, and the purpose of adjusting the tightness of the connecting band can be achieved by simply moving the operating member 340, and the operation is simple and convenient.

[0022] Optionally, a slide groove may be further provided on the fixing seat 310, and the operating member 340 may be movably provided in the slide groove, and a portion of the operating member 340 may extend out of the fixing seat 310 to facilitate user operation.

[0023] In an optional embodiment of the present application, the locking member 330 may include a first magnetic member 331 and a second magnetic member 332, the first magnetic member 331 may be provided on the operating member 340, the second magnetic member 332 may be provided on the clamping member 320, and the first magnetic member 331 and the second magnetic member 332 may be magnetically matched to lock the clamping member 320. The clamping member 320 may be locked by the magnetic matching of the first magnetic member 331 and the second magnetic member 332, so that the clamping member 320 and the first connecting belt 100 are kept in a clamping state to prevent the first connecting belt 100 from being moved due to force.

[0024] Here, the method of locking the clamp 320 by magnetically cooperating with the first magnetic part 331 and the second magnetic part 332 is compared with the method of locking the clamp 320 by using a spring described below. On the one hand, the first magnetic part 331 and the second magnetic part 332 are not easily affected by the external environment, have better reliability, and are easier to keep the clamp 320 in a clamped state. In addition, the first magnetic part 331 and the second magnetic part 332 are not easily worn and deformed, and thus have a longer service life than the spring. On the other hand, they occupy less space and can be conveniently set on the clamp 320 and the operating part 340.

[0025] In other embodiments, the locking member 330 can be a spring, and the two ends of the spring can be connected to the operating member 340 and the clamping member 320 respectively, and when the spring is not deformed, the clamping member 320 can be clamped with the first connecting band 100, and when the spring is deformed, the clamping member 320 is separated from the first connecting band 100. Specifically, moving the operating member 340 can compress or stretch the spring, causing the spring to deform and no longer lock the clamping member 320, so that the clamping member 320 can be separated from the first connecting band 100.

[0026] In an optional embodiment, a third magnetic member 350 may also be provided on the operating member 340. Along the moving direction of the operating member 340, the first magnetic member 331 and the third magnetic member 350 may be arranged at intervals, and the third magnetic member 350 and the second magnetic member 332 may be magnetically matched to unlock the card member 320. In this way, compared with the method of only moving the first magnetic member 331 away from the second magnetic member 332, it is easier to unlock the card member 320, thereby facilitating the separation of the card member 320 from the first connecting belt 100 and keeping the card member 320 in a separated state. In addition, the card member 320 and the first connecting belt 100 can be connected and separated only by moving the operating member 340, which is convenient to operate.

[0027] Here, the magnetism of one end of the first magnetic member 331 facing the second magnetic member 332 and the magnetism of one end of the third magnetic member 350 facing the second magnetic member 332 may be opposite.

[0028] In other embodiments, the third magnetic member 350 may not be provided on the operating member 340. Specifically, by moving the operating member 340, the first magnetic member 331 is moved away from the second magnetic member 332, so that the first magnetic member 331 and the second magnetic member 332 no longer lock the clamping member 320, and the clamping member 320 is no longer in the clamping state.

[0029] Optionally, the operating member 340 may be provided with an isolating portion 341, which is located between the first magnetic member 331 and the second magnetic member 332, so as to isolate the first magnetic member 331 from the third magnetic member 350. In this way, when the first magnetic member 331 and the second magnetic member 332 are magnetically matched, the isolating portion 341 can reduce the interference of the third magnetic member 350 on the second magnetic member 332, and when the third magnetic member 350 and the second magnetic member 332 are magnetically matched, the isolating portion 341 can reduce the interference of the third magnetic member 350 on the second magnetic member 332. Here, the isolating portion 341 may be a silicon steel block.

[0030] It should be noted that, as described above, the first magnetic member 331 and the third magnetic member 350 can be separately provided. Of course, the first magnetic member 331 and the third magnetic member 350 can also be provided as an integrated structure. Specifically, a long magnet can be used to replace the first magnetic member 331 and the third magnetic member 350. The length direction of the long magnet can be the same as the moving direction of the operating member 340, and the first end of the long magnet can be magnetically attracted to the second magnetic member 332, that is, the polarity of the first end of the long magnet and the end of the second magnetic member 332 close to the operating member 340 can be opposite; the long magnet The second end of the long magnet can be magnetically repelled from the second magnetic member 332, that is, the second end of the long magnet and the end of the second magnetic member 332 close to the operating member 340 can have the same polarity, so that when the operating member 340 is in the first position, the first end of the long magnet is magnetically attracted to the second magnetic member 332 to lock the clamp 320, thereby making the clamp 320 and the first connecting belt 100 clamped; when the operating member 340 is in the second position, the second end of the long magnet is magnetically repelled from the second magnetic member 332 to unlock the clamp 320, thereby making the clamp 320 no longer clamped to the first connecting belt 100. Here, the polarity of the end of the second magnetic member 332 close to the operating member 340 can be an N pole, the polarity of the first end of the long magnet can be an S pole, and the polarity of the second end of the long magnet can be an N pole.

[0031] In an optional embodiment, if Figure 2-Figure 5 As shown, the clamping member 320 can be rotatably connected to the fixing seat 310, and the clamping member 320 can rotate between a first rotation position and a second rotation position. When the clamping member 320 is located at the first rotation position, the clamping member 320 is clamped with the first connecting belt 100, and when the clamping member 320 is located at the second rotation position, the clamping member 320 is separated from the first connecting belt 100. When the operating member 340 drives the first magnetic member 331 to move to a position opposite to the second magnetic member 332, the clamping member 320 can be rotated to the first rotation position and maintained at the first rotation position due to the magnetic effect between the first magnetic member 331 and the second magnetic member 332; when the operating member 340 drives the third magnetic member 350 to move to a position opposite to the second magnetic member 332, the clamping member 320 can be rotated to the second rotation position and maintained at the second rotation position due to the magnetic effect between the third magnetic member 350 and the second magnetic member 332.

[0032] Optionally, the clamping member 320 may include a rotating plate 321 and a clamping portion 322, the rotating plate 321 may be rotatably connected to the fixing seat 310 via a rotating shaft, so that the clamping member 320 may be rotatably disposed on the fixing seat 310, the clamping portion 322 may be connected to the rotating plate 321, and the clamping portion 322 may be used to clamp with the first connecting belt 100, and the second magnetic member 332 may be disposed on the rotating plate 321. Here, the manner in which the clamping member 320 is rotatably disposed on the fixing seat 310 occupies less space than the manner in which the clamping member 320 is movably disposed on the fixing seat 310, thereby facilitating miniaturization of the tension adjustment device 300.

[0033] In the case where the clamping portion 322 and the second magnetic member 332 are located on opposite sides of the rotating shaft, the first magnetic member 331 and the second magnetic member 332 can be magnetically attracted to each other to lock the clamping member 320, thereby keeping the clamping member 320 in a clamping state with the first connecting belt 100. This arrangement makes it easier to balance the force on the clamping member 320, thereby facilitating the driving of the clamping member 320 to rotate and helping to extend the service life of the clamping member 320.

[0034] When the clamping portion 322 and the second magnetic member 332 are both located on the same side of the rotating shaft, the first magnetic member 331 and the second magnetic member 332 can magnetically repel each other to lock the clamping member 320, thereby keeping the clamping member 320 and the first connecting belt 100 in a clamping state. This arrangement is conducive to reducing the space occupied by the clamping member 320.

[0035] In other embodiments, the clamping member 320 is movably disposed on the fixing seat 310, and when the first magnetic member 331 and the second magnetic member 332 are opposite to each other, the clamping member 320 can move toward the first connecting band 100 and be engaged with the first connecting band 100; when the third magnetic member 350 and the second magnetic member 332 are opposite to each other, the clamping member 320 can move away from the first connecting band 100 and be separated from the first connecting band 100.

[0036] Optionally, a receiving groove may be provided on the fixing seat 310, and the clamping member 320 may be rotatably provided in the receiving groove. Specifically, the rotating plate 321 of the clamping member 320 may be connected to the groove wall of the receiving groove through a rotating shaft, and the receiving groove may be communicated with the channel 311, and the clamping portion 322 of the clamping member 320 may extend into the channel 311 and be clamped with the first connecting belt 100. Here, the receiving groove may also be communicated with the sliding groove, so that the first magnetic member 331 and the third magnetic member 350 on the operating member 340 are magnetically matched with the second magnetic member 332 respectively.

[0037] In an optional embodiment, the operating member 340 is telescopically disposed on the fixed seat 310. By pressing the operating member 340, the first magnetic member 331 can be moved away from the second magnetic member 332, and the third magnetic member 350 can be moved to a position opposite to the second magnetic member 332. At this time, the third magnetic member 350 and the second magnetic member 332 can repel each other. In this state, the clamping member 320 is separated from the first connecting belt 100 and no longer fixes the first connecting belt 100, so that the first connecting belt 100 can move freely to adjust the tightness of the connecting belt assembly. When the pressing of the operating member 340 stops, the reset driving member 360 described later can drive the operating member 340 to reset, and the operating member 340 drives the third magnetic member 350 away from the second magnetic member 332, and the first magnetic member 331 moves to a position opposite to the second magnetic member 332. At this time, the first magnetic member 331 and the second magnetic member 332 can attract each other. In this state, the clamping member 320 is clamped with the first connecting belt 100 and keeps the clamping member 320 stably in the clamped state.

[0038] In another embodiment of the present application, Figure 9-14 As shown, the clamping member 320 is movably disposed on the fixing seat 310, and the clamping member 320 can move between a first moving position and a second moving position. When the clamping member 320 is located at the first moving position, the clamping member 320 can be engaged with the first connecting belt 100, and when the clamping member 320 is located at the second moving position, the clamping member 320 can be separated from the first connecting belt 100. In addition, in the moving direction of the operating member 340, the clamping member 320 can be limitedly matched with the operating member 340 to drive the clamping member 320 to move. In this way, the structure is simple and easy to install.

[0039] When the operating member 340 is in the first position, the locking member 330 locks the locking member 320 in the first moving position, so that the locking member 320 remains in a state of being engaged with the first connecting belt 100 .

[0040] When the operating member 340 is at the second position, the operating member 340 drives the locking member 320 to move to the second moving position and unlocks the locking member 330 , so that the locking member 330 no longer locks the locking member 320 .

[0041] In other embodiments, the clamping member 320 is rotatably disposed on the fixing base 310 .

[0042] In an optional embodiment, the operating member 340 may be provided with a guide groove 342, and a portion of the clamping member 320 may be located in the guide groove 342. In the moving direction of the operating member 340, the guide groove 342 and the clamping member 320 may be slidably matched. In this way, the guide groove 342 may guide and limit the clamping member 320 to ensure that the clamping member 320 does not deviate during the movement.

[0043] Of course, the guide groove 342 may not be provided on the operating member 340 , and the end of the operating member 340 may contact the clamping member 320 , and moving the operating member 340 may enable the operating member 340 to push the clamping member 320 to move.

[0044] Optionally, at least one of the clamping member 320 and the operating member 340 may be provided with a driving inclined surface 343, and the operating member 340 may push the clamping member 320 to move through the driving inclined surface 343. At this time, the moving direction of the operating member 340 may intersect with the moving direction of the clamping member 320, and may further be perpendicular to the moving direction of the clamping member 320. In this way, under the action of the driving inclined surface 343, the clamping member 320 is more likely to move from the first moving position to the second moving position. Here, both the clamping member 320 and the operating member 340 may be provided with a driving inclined surface 343, and when the operating member 340 moves, the driving inclined surface 343 of the clamping member 320 and the driving inclined surface 343 of the operating member 340 may fit together. In this way, in the process of pushing the clamping member 320 to move, the driving inclined surface 343 of the clamping member 320 and the driving inclined surface 343 of the operating member 340 can fit together, so that the clamping member 320 and the operating member 340 can achieve surface-to-surface contact, thereby facilitating the pushing of the clamping member 320 to move and reducing the stress between the clamping member 320 and the operating member 340, thereby helping to extend the service life of the clamping member 320 and the operating member 340.

[0045] Of course, both the clamping member 320 and the operating member 340 may not be provided with the driving inclined surface 343. Specifically, the operating member 340 may directly contact the clamping member 320 and push the clamping member 320 to move. At this time, the moving direction of the operating member 340 may be parallel to the moving direction of the clamping member 320.

[0046] In one embodiment, when the operating member 340 moves in the first direction, the operating member 340 can push the clamping member 320 to move through the driving inclined surface 343. Here, in the first direction, the distance between the driving inclined surface 343 and the first connecting belt 100 can be gradually reduced. It should be noted that the driving inclined surface 343 is located on the first side of the clamping member 320. In this way, when the operating member 340 moves in the first direction, the driving inclined surface 343 can contact the clamping member 320, and the clamping member 320 can move along the driving inclined surface 343 in a direction away from the first connecting belt 100, thereby realizing the separation of the clamping member 320 from the first connecting belt 100. In another embodiment, when the operating member 340 moves in the second direction, the second direction may be the opposite direction of the first direction, and the operating member 340 may push the clamping member 320 to move through the driving inclined surface 343. Here, in the second direction, the distance between the driving inclined surface 343 and the first connecting belt 100 may gradually decrease. It should be noted that the driving inclined surface 343 is located on the second side of the clamping member 320, and the first side of the clamping member 320 and the second side of the clamping member 320 are opposite sides in the moving direction of the operating member 340. In this way, when the operating member 340 moves in the second direction, the driving inclined surface 343 may contact the clamping member 320, and the clamping member 320 may move in the direction away from the first connecting belt 100 along the driving inclined surface 343, thereby realizing the separation of the clamping member 320 from the first connecting belt 100. Optionally, the operating member 340 may be telescopically arranged on the fixing seat 310, and the above-mentioned first direction may be the contraction direction of the operating member 340, and the second direction may be the extension direction of the operating member 340.

[0047] In an optional embodiment, the locking member 330 may include an elastic member 333, both ends of which may be connected to the fixing seat 310 and the clamping member 320 respectively, and the elastic member 333 may be used to drive the clamping member 320 to clamp with the first connecting belt 100. In this way, the clamping member 320 may be clamped with the first connecting belt 100 under the thrust of the elastic member 333 and remain in the clamped state.

[0048] Here, the method of using the elastic member 333 to keep the clamping member 320 in the clamping state is simple in structure, easy to implement, and low in cost compared to the method of using the first magnetic member 331 and the second magnetic member 332 to keep the clamping member 320 in the clamping state.

[0049] Of course, the locking member 330 may include the first magnetic member 331 and the second magnetic member 332 described above, and the locking member 320 is kept in the locked state through the magnetic cooperation between the first magnetic member 331 and the second magnetic member 332 .

[0050] Optionally, when the clamping member 320 is rotatably connected to the fixing seat 310, one end of the elastic member 333 can be connected to the rotating plate 321, and the elastic member 333 and the clamping portion 322 are both located on the same side of the rotating shaft. The elastic member 333 can push the rotating plate 321 to rotate to the first rotation position so that the clamping portion 322 is clamped with the first connecting belt 100, and the operating member 340 can drive the elastic member 333 to compress and deform, so that the elastic member 333 no longer locks the clamping member 320, thereby allowing the clamping member 320 to rotate to the second rotation position and separate from the first connecting belt 100.

[0051] When the clamping member 320 is movably connected to the fixing seat 310, one end of the elastic member 333 can be connected to the end of the clamping member 320 that is away from the first connecting belt 100. Under the elastic force of the elastic member 333, the clamping member 320 can clamp the first connecting belt 100 and remain stably in the clamped state; when the operating member 340 pushes the clamping member 320 to move by driving the inclined surface 343, the clamping member 320 compresses the elastic member 333. At this time, the clamping member 320 no longer clamps the first connecting belt 100. When the operating member 340 is reset, the elastic member 333 restores its deformation and pushes the clamping member 320 to clamp the first connecting belt 100.

[0052] Further optionally, the locking member 330 may include at least two elastic members 333 , and two ends of each elastic member 333 are respectively connected to the fixing seat 310 and the clamping member 320 , so as to facilitate rapid driving of the clamping member 320 to clamp with the first connecting belt 100 .

[0053] In an optional embodiment, the tension adjustment device 300 may further include a reset driver 360, the two ends of which may be connected to the fixing seat 310 and the operating member 340 respectively, and the reset driver 360 may be used to drive the operating member 340 to reset. In this way, when the external force on the operating member 340 disappears, the operating member 340 can be quickly and automatically reset, so that the locking member 330 can lock the clamping member 320 again, and then the clamping member 320 continues to be clamped with the first connecting belt 100, so that the first connecting belt 100 and the second connecting belt 200 are relatively fixed; and it is convenient for the user to operate again.

[0054] In other embodiments, the tension adjustment device 300 may not include the reset drive member 360 . Here, the user may manually reset the operating member 340 .

[0055] Optionally, the reset driving member 360 may be a spring, so that the structure of the reset driving member 360 is simple and the cost is low.

[0056] Further optionally, the tension adjustment device 300 may include at least two reset driving members 360 , and both ends of each reset driving member 360 may be connected to the fixing seat 310 and the operating member 340 , respectively, so as to facilitate rapid reset of the operating member 340 .

[0057] In this embodiment, the tension adjustment device 300 may include two reset driving members 360 , and the two reset driving members 360 may be evenly distributed in the width direction of the first connecting belt 100 , which is helpful to ensure that the force of the operating member 340 is balanced.

[0058] Here, in the case where the operating member 340 is provided with the guide groove 342 , the two reset driving members 360 may be located at both sides of the guide groove 342 in the width direction.

[0059] Based on the tension adjustment device 300 provided in the embodiment of the present application, the embodiment of the present application also provides a connecting belt assembly, which may include a first connecting belt 100, a second connecting belt 200 and the tension adjustment device 300 described in any of the above embodiments, wherein the first connecting belt 100 and the second connecting belt 200 can both be connected to the fixed seat 310 of the tension adjustment device 300, and at least one of the first connecting belt 100 and the second connecting belt 200 can be slidably matched with the fixed seat 310, and the clamping piece 320 of the tension adjustment device 300 can be clamped with the first connecting belt 100 to relatively fix the first connecting belt 100, the second connecting belt 200 and the fixed seat 310.

[0060] The beneficial effects achieved by the connecting belt assembly provided in the embodiment of the present application are consistent with the beneficial effects achieved by the tension adjustment device 300 provided in the embodiment of the present application, and will not be described in detail here.

In this way, the first connecting belt 100 and the second connecting belt 200 are both passed through the channel 311, and when the tightness of the connecting belt assembly needs to be adjusted, the tightness can be adjusted regardless of adjusting the extension length of the first connecting belt 100 or the extension length of the second connecting belt 200, and the tightness can be infinitely adjusted by adjusting the extension length of the second connecting belt 200.

Specifically, the first end of the first connection belt 100 can pass through the channel 311 from the first end of the channel 311, and the first end of the second connection belt 200 can be connected to one end of the fixing seat 310. When the clamping member 320 is clamped with the first connection belt 100, the first connection belt 100 is in contact with the fixing seat 310 or the second connection belt 200, thereby achieving relative fixation of the first connection belt 100 and the second connection belt 200.

[0064] Here, the first connecting belt 100 may be provided with a plurality of tooth grooves 110 , and the plurality of tooth grooves 110 may be distributed along the length direction of the first connecting belt 100 . The clamping member 320 may be clamped with the tooth grooves 110 to achieve clamping of the clamping member 320 with the first connecting belt 100 .

[0065] Optionally, the channel 311 may be a through hole penetrating the fixing seat 310, that is, the fixing seat 310 may be coated on the circumference of the stacked first connecting belt 100 and the second connecting belt 200, or the fixing seat 310 may only be coated on the circumference of the first connecting belt 100. Of course, the channel 311 may not be a through hole, but may be a through groove, that is, the fixing seat 310 may be a U-shaped structure, and the fixing seat 310 may not be coated on at least one of the first connecting belt 100 and the second connecting belt 200.
