The invention proposes a wearable device.

In an embodiment of the present invention, as shown in Figure 1 and Figure 2, the wearable device includes:

The device main body 100 is provided with a controller;

Two straps, the straps include a first strap 200 and a second strap 300, one end of the first strap 200 and the second strap 300 are respectively connected to the two ends of the device main body 100, and the other end is used for connected to each other, and the two belts are partially overlapped;

A tightness adjustment mechanism is provided on the belt, and adjusting the tightness adjustment mechanism can change the overlapping length of the two belts to adjust the tightness of the wearable device; and

The length detection mechanism is electrically connected to the controller and used to detect the overlapping length of the two belts.

It can be understood that the two ends of the belt are respectively a free end and a fixed end, the fixed end of the belt is used to be connected to the end of the device main body 100, and the free ends of the two belts are used to connect to each other, so that the two belts can be connected with each other. The device main body 100 together forms a wearing circle. The size of the wearing circle should be adapted to the user's head, hands or feet, so that the tightness of the wearable device meets the needs of the user, thereby improving the comfort of the user wearing the wearable device. Among them, wearable devices include: watches, smart watches or smart bracelets that can be worn on the wrist, motion monitoring modules that can be worn on the feet, and 3D display devices that can be worn on the head.

In the present invention, the size of the wearing circle can be judged according to the overlapping length detected by the length detection mechanism. Therefore, the optimum overlapping length is determined, and the wearing circle will correspond to the size with the highest comfort. Without loss of generality, the wearable device of the present invention can calibrate the optimal overlapping length in the following two ways:

The first way is to determine the most comfortable wearing circle for the user according to the circumference of the body part where the user wears the wearable device; The most durable wearing circle. The overlapping length of the two belts at this time is detected by the length detection mechanism, which is the optimum overlapping length.

The size of the wearing circle can be changed by changing the overlapping length of the two belts. Therefore, after determining the wearing circle with the highest comfort, when the user wears the wearable device, he can first make a rough adjustment and let the length detection mechanism detect the two belts. The current overlap length, the difference between the current overlap length and the optimum overlap length is the length adjustment value, because the length detection mechanism is electrically connected to the controller, the controller can obtain the length adjustment by obtaining the current overlap length and the optimum overlap length value and give feedback to the user. The user can change the overlapping length of the two belts by adjusting the tightness adjustment mechanism. Can be adjusted to the most comfortable size. In this way, the wearable device of the present invention can adjust the tightness more accurately, thereby improving the wearing comfort of the user.

Please refer to Figure 3, in some embodiments, the length detection mechanism includes:

A resistance element 320 is arranged on the second belt body 300 and electrically connected to the controller;

A lead piece is provided on the first belt body 200, one end of the lead piece is electrically connected to the controller, and the other end is used to conduct the resistance element 320; and

resistance detection element 110, electrically connected to the controller;

The conductor is connected to the resistor 320, and a detection loop is formed between the controller, the resistance detection element 110, the conductor and the resistor 320;

Corresponding to the different overlapping lengths of the two strips, the conductors are connected to different positions of the resistor 320, so that the resistance of the resistor 320 connected to the detection loop is different;

The resistance detection element 110 detects the resistance of the resistance element 320 connected to the detection loop to represent the overlapping length of the two strips.

In this way, a resistance value of the resistance detection element 110 will correspond to an overlapping length of the two belts. In this embodiment, the size of the overlapping length is represented by the resistance value, which is convenient, fast and accurate, and can provide precise adjustment for tightness. basis to ensure the user's wearing comfort.

Further, the resistance element 320 is arranged in a strip shape extending along the length direction of the second strip 300, corresponding to the different overlapping lengths of the first strip 200 and the second strip 300, the The lengths of the resistors 320 connected to the detection loop are different.

It can be understood that each belt should have a portion for overlapping with another belt at the end far away from the device main body 100, and at least this part of the second belt 300 should be distributed with strip-shaped resistors 320, and the conductors It should also be arranged on the first belt body 200 of this part, and within the adjustable range of overlapping length, the lead should always be arranged relative to the resistor 320 to ensure that the lead can be connected to the resistor 320, so , when changing the overlapping length of the two strips, the resistance detection element 110 can always detect the resistance value corresponding to the current overlapping length. In particular, when the resistive element 320 is arranged in a uniform elongated structure, the resistance value of the resistive element 320 connected to the detection loop will have a linear relationship with the length of the connected detection loop, and the length adjustment value can be obtained more conveniently.

Of course, the resistance element can also be formed by connecting multiple resistance elements in series. Corresponding to the different overlapping lengths of the two belts, the number of resistance elements connected to the detection loop is different. In this way, the resistance value detected by the resistance elements can also be used to characterize the two belts. body overlap length.

Please refer to FIG. 6 to FIG. 9 together. Further, the tightness adjustment mechanism includes an adjustment member 210 provided at the end of the first belt body 200 and a rack provided at the second belt body 300 structure 310, the adjustment member 210 is provided with an adjustment cavity 211, at least the rack structure 310 can move in and out of the adjustment cavity 211; the tightness adjustment mechanism also includes a buckle 220, and the buckle 220 can Rotately provided in the adjustment cavity 211 to have a first state and a second state; in the first state, the buckle 220 engages with the rack structure 310 to drive the adjustment member 210 to move, It can drive the buckle 220 to move relative to the rack structure 310, so as to change the length of the rack structure 310 extending into or protruding from the adjustment cavity 211, so as to increase the overlap of the second belt body 300 The length of the first belt 200; in the second state, the buckle 220 can be separated from the rack structure 310, so that the second belt 300 can exit the adjustment cavity 211 direction to reduce the overlapping length of the second belt body 300 on the first belt body 200 .

In this embodiment, the rack structure 310 includes a plurality of tooth grooves 311 arranged at intervals. After the second belt body 300 is inserted into the adjustment cavity 211, the buckle 220 can be adjusted to the first state, so that the buckle 220 is engaged. In one of the slots 311 of the rack structure 310 , the second belt 300 can be stably connected to the first belt 200 without external force.

When it is necessary to increase the overlapping length of the two straps, the user should also apply force to the second strap 300 while applying force to drive the adjustment member 210, so that the buckle 220 will be in a plurality of tooth grooves of the rack structure 310. 311, so that the length of the second belt body 300 extending into or out of the adjusting cavity 211 is longer. It can be understood that before the second belt body 300 is fully extended into the adjustment cavity 211, the longer the length of the second belt body 300 inserted into the adjustment cavity 211 is, the longer the overlapping length of the two belt bodies is; After entering the adjustment cavity 211 , the longer the length of the second belt 300 extending out of the adjustment cavity 211 , the longer the overlapping length of the two belts.

When it is necessary to reduce the overlapping length of the two belts, the buckle 220 should be adjusted to the second state, so that the buckle 220 is separated from the tooth groove 311 of the rack structure 310, and the second belt 300 can be easily Move towards the direction of exiting the adjustment cavity 211 to meet the user's adjustment needs.

Without loss of generality, in this embodiment, the adjustment cavity 211 is arranged on the opposite side of the wearing side p of the first belt body 200, so that after the second belt body 300 is inserted into the adjustment cavity 211, the second belt body 300 can surround the The outer side of the first belt body 200 is convenient for the user to apply force, which can improve the convenience for the user to adjust the tightness. The adjustment member 210 is composed of two parts fixedly connected by pins, and the two parts limit the adjustment cavity 211 together. In this way, other parts of the tension adjustment mechanism can be installed in a part of the adjustment part 210 first, and then another part of the adjustment part 210 can be fixed, which can improve the assembly convenience of the tightness adjustment mechanism. At this time, the adjustment chamber 211 has no other openings except the inlet and outlet. Of course, in other embodiments, the adjusting part can also be an integral structure, which can be opened on the side to facilitate the assembly of other parts, and the adjusting cavity also has other openings except the inlet and outlet, but only need to ensure It only needs to be unable to disengage from the adjustment cavity from the opening.

In this way, the buckle 220 can be directly connected to the resistor 320 by contacting the surface of the resistor 320 .

Further, when the resistive element 320 is long, the material of the resistive element 320 is a memory metal material, and the resistive element 320 has a memory state that is arc-shaped in a natural state, so that the second Band 300 is at least partially curved in nature. It can be understood that the memory metal has superelasticity, which means that under the action of external force, the memory metal has a much greater deformation recovery ability than ordinary metals, that is, the large strain generated during the loading process will be eliminated with unloading, thereby returning to the memory shape . In this embodiment, the resistive element 320 is set as a memory metal material, which can have both electrical conductivity and deformation recovery ability, and can avoid the change of the relative position between the resistive element 320 and the tooth groove 311 due to the deformation of the resistive element 320, which will cause the buckle 220 cannot be connected to the resistor 320 to ensure the stability of the length detection mechanism.

In the length direction of the second belt 300, different colors are distributed at different positions of the detection part. As the overlapping length of the two belts changes, the different positions of the color sensor 250 relative to the detection part can identify different colors. so that a color identified by the color sensor 250 corresponds to an overlapping length of the two tapes, so that the identification result of the color sensor 250 can characterize the overlapping length of the two tapes. In this way, it is also convenient, quick and accurate to provide a basis for adjusting the tightness, so as to ensure the wearing comfort of the user.

Further, there are multiple detection parts, and the multiple detection parts are distributed in different positions along the length direction of the second belt 300 .

The color sensor 250 is arranged on the buckle 220, and the buckle 220 is engaged with different tooth grooves 311, so that the overlapping length of the two belts can be changed, and the color sensor 250 can identify different colors , and the color identified by the color sensor 250 corresponds to the current overlapping length.

It can be understood that when the buckle 220 engages with different tooth grooves 311, it can drive the two straps to move relative to each other, so that the overlapping lengths of the two straps are different, thereby realizing the adjustment of the tightness of the wearable device, and the clip The fastener 220 is provided with a color sensor 250. Different tooth grooves 311 can reflect or emit light of different colors. The color sensor 250 can detect the tooth groove where the buckle 220 is located by identifying the color of the light from the tooth groove 311. 311, the overlapping length of the two belts can be correspondingly obtained at this time. In this way, the cooperation of the buckle 220 and the tooth groove 311 can not only realize the tightness adjustment of the wearable device, but also enable the length detection mechanism to detect the overlapping length of the two belts, so as to ensure that the detection result of the length detection mechanism can be synchronized with the The adjustment process of the tightness adjustment mechanism ensures the accuracy of the tightness adjustment, and also ensures that the length detection mechanism can detect the overlapping length of the two belts within the adjustment range.

Of course, in other embodiments, it is also possible that the adjustment member is provided with an adjustment hole, and the user inserts a finger or a strip into the adjustment hole to directly act on the buckle, so that the buckle can also be in the first state and Switch between the second state.

Further, the rack structure 310 includes a plurality of tooth slots 311 arranged at intervals, the buckle 220 has an engaging end 221, and in the first state, the engaging end 221 obliquely engages with the tooth slots within 311;

The tooth groove 311 has opposite first side a and second side b, and the buckle 220 moves from the first side a of one tooth groove 311 to the other adjacent tooth groove 311 , can increase the overlapping length of the two strips;

On the first side a, each tooth groove 311 is provided with a guiding slope 312 parallel to the engaging end 221, and the guiding inclined surface 312 is used to guide the engaging end 221 from the first side a. into another adjacent tooth groove 311 .

When adjusting the tightness adjustment mechanism to increase the overlapping length of the two belts, the user can first fix the adjusting member 210, and then pull the free end of the second belt 300 to make the tooth slots 311 of the rack structure 310 sequentially Slide over the buckle 220 until it is adjusted in place. When the wearable device is worn on the head or feet, it can be adjusted by fixing the adjustment part 210 with one hand and pulling the second belt body 300 with the other hand. When the wearable device is worn on the user's wrist, the adjustment part can be adjusted 210 is pressed against the desktop, and the second belt body 300 can be adjusted by pulling the other hand. Under the guidance of the guide slope 312, the buckle 220 can smoothly slide over the first side a of the tooth groove 311, and the user can pull the second belt 300 with less effort, which is beneficial to improve the user's operating experience of adjusting the tightness.

Further, on the second side b, each of the tooth grooves 311 is provided with a limiting surface 313, and the limiting surface 313 is set at an acute angle or at a right angle to the bottom wall of the tooth groove 311, so as to limit the The engaging end 221 enters another adjacent tooth groove 311 from the second side b.

It can be understood that, for the convenience of the user to wear, in the natural state of the wearable device, the cooperation between the first strap body 200 and the second strap body 300 is relatively loose, and after the wearable device is worn on the human body, the first strap body 200 The fit between the second belt body 300 is tight, thus causing the second belt body 300 to have a tendency to separate from the first belt body 200 . In this embodiment, the second side b of the tooth groove 311 has a limiting surface 313 set at an acute angle or at right angles to the bottom wall of the tooth groove 311, so as to restrict the engaging end 221 from entering the adjacent other side b from the second side b. The grooves 311 are formed to suppress the tendency of the second belt body 300 to separate from the first belt body 200 .

Further, the tightness adjustment mechanism further includes an elastic member, and the elastic member can act on the buckle 220 to make the buckle 220 move from the second state to the first state. the trend of.

In the natural state of the elastic member, if there is no external force, the buckle 220 can be stably in the first state, so that the buckle part is locked in a tooth groove 311, thereby locking the two belts together to ensure that the two belts body stable connection. In addition, when the toggle part 231 is driven to drive the buckle 220 to move to the second state, after the overlapping length of the two straps is adjusted, the force applied to the toggle part 231 is removed. The trend of resetting the state can drive the buckle 220 to move in the direction of restoring the first state, so that the buckle 220 can finally be locked in the corresponding tooth groove 311, and the locking of the two belts can be realized again. . Of course, in other embodiments, it is also possible that a limit buckle is provided on the outside of the adjustment member, and when the toggle part engages with the limit buckle, the buckle is correspondingly in the first state.

Without loss of generality, in one embodiment of the present invention, as shown in FIG. 8 , when the buckle 220 is in the first state and engaged in the tooth groove 311 and the torsion spring 240 is in the natural state, the buckle 220 and the There is a certain gap between the second torsion arms 242. When the engaging end 221 slides toward the adjacent tooth groove 311 along the guide slope 312, the buckle 220 will move toward the second torsion arm 242 by the reaction force of the guide slope 312. The direction is offset, and the offset is large enough to abut against the second torsion arm 242, and after the engaging end 221 enters the tooth groove 311, the shape of the tooth groove 311 matches the shape of the engaging end 221, and the engaging end 221 engages with the In the tooth groove 311 , the buckle 220 can return to the first state, and keep a certain distance from the second torsion arm 242 of the torsion spring 240 in the natural state. In this way, when the overlapping length of the two straps is increased, the buckle 220 is subjected to a smaller elastic force, and the user can pull the second strap 300 with less effort. When the buckle 220 is in the second state, the torsion spring 240 cannot directly drive the buckle 220 to the first state when the torsion spring 240 returns to the natural state, and the torsion spring 240 will be in the corresponding state. The position abutting against the second torsion arm 242 is not restored to the first state until the buckle 220 is engaged in the tooth groove 311 . Of course, in other embodiments, it may also be that, in the first state, the buckle is in contact with the second torsion arm.

Further, as shown in FIG. 8 and FIG. 9, two torsion springs 240 are provided, and the two torsion springs 240 are respectively arranged on opposite sides of the buckle 220, and the two torsion springs 240 The second torsion arms 242 are connected to each other as a whole.

The force 220 is too large to cause deformation of the second torsion arm 242 .

Further, the wearable device further includes a tightness sensing element electrically connected to the controller, the tightness sensing element is arranged on the wearing side p of the wearable device, and is used to detect the tightness of the wearable device. Tightness. The tightness sensor can detect the tightness of the wearable device. The tightness of the wearable device is also related to the size of the wearing circle and the circumference of the user's wearing part, which can more intuitively reflect the user's wearing comfort. When the user wears the wearable device for the first time, in order to facilitate the user to determine the size of the most suitable wearing circle, the controller of the device body 100 can pre-store the preset tightness recommended in ergonomics, and different parts should have different most comfortable When the user adjusts the tightness adjustment mechanism until the detection result of the tightness sensor corresponds to the preset tightness, the user can confirm whether it is comfortable or not. If the user feels loose or tight, he can continue to fine-tune. Until the most suitable tightness that the user thinks is reached, in this way, the workload of the user to determine the most suitable wearing circle can be greatly reduced.

Further, as shown in FIG. 3 to FIG. 5 , the tightness sensing element is a pressure sensor 260 , and the tightness of the wearable device is represented by the pressure value detected by the pressure sensor 260 . Considering that the device main body 100 does not have flexibility and poor fit with human skin, the pressure sensor 260 is set away from the device main body 100, and the detection effect is better. For example, the pressure sensor 260 can be arranged on the first belt 200, the second belt The wearing side p of the body 300 or the adjuster 210 . Without loss of generality, in this embodiment, the pressure sensor 260 is arranged on the wearing side p of the first belt body 200, and is arranged close to the adjustment member 210. In this way, after the user wears the wearable device, the pressure sensor 260 will be located between the human skin and the second belt. A belt body 200, so that the pressure of the interaction between the two can be sensed. It can be understood that this pressure value is closely related to the tightness of the wearable device. The larger the pressure value, the tighter the wearable device is worn on the human body. , thus, the pressure value detected by the pressure sensor 260 can represent the tightness of the wearable device. Of course, in other embodiments, the tightness sensor can also be a friction sensor. By making the wearable device slightly rotate relative to the wearing part of the human body, the friction sensor detects the friction between the belt and the human skin to represent the wearable device. The tightness of the device.

Further, a pressure value detected by the pressure sensor 260 corresponds to an overlapping length of the two belts, and the controller is used to obtain the target overlapping length according to the target pressure value, and obtain the current overlapping length detected by the length detection mechanism. length, so as to obtain a length adjustment value according to the target overlapping length and the current overlapping length, so that the tightness adjusting mechanism adjusts the overlapping length of the two belts to the target overlapping length according to the length adjusting value.

When the user wears the wearable device for the first time, the tightness can be calibrated for different tooth grooves 311. Firstly, the buckle 220 is engaged in the tooth groove 311 closest to the free end of the second belt 300. At this time, the wearing circle Then, by pulling the second belt body 300, a plurality of tooth grooves 311 pass through the buckle 220 in turn until the two belts can no longer be tightened or the buckle 220 reaches the free space from the second belt 300. in the furthest alveolar 311. In this process, the length detection mechanism feeds back the detection value corresponding to the overlapping length of the two belts (such as resistance value, color, or Hall voltage, etc.) to the controller in turn, and at the same time, the pressure sensor 260 feeds back the pressure value, and the controller stores the detection value and pressure value corresponding to each cogging slot 311. When the user needs to reach a certain target pressure value, the controller can call the detection value corresponding to the target pressure value to determine the tooth groove 311 that the buckle 220 needs to reach. At this time, the length detection mechanism detects that the current buckle 220 The cogging 311 where it is located, the controller can give adjustment instructions after receiving the information, and the adjustment instructions include loosening or tightening, and the specific number of cogging 311 to be adjusted. It can be understood that the target pressure value includes the optimal pressure value corresponding to the optimal tightness. At this time, the target overlapping length is also the optimal overlapping length. The user can mark the optimal pressure value. During daily wear, the controller calls The overlapping length corresponding to the optimum pressure value is fed back to the user, and the user can easily adjust the overlapping length of the two belts to the optimum overlapping length by adjusting the tightness adjustment mechanism.

Further, the pressure sensor 260 is also used to detect the actual pressure value after the overlapping length of the two belts is adjusted to the target overlapping length, the controller acquires the actual pressure value, and judges whether the actual pressure value is consistent with the target overlapping length. Whether the difference between the target pressure values is less than or equal to the preset pressure difference. In this way, the actual pressure value detected by the pressure sensor 260 can provide another accurate basis for adjusting the tightness of the wearable device. Before the user adjusts the tightness adjustment mechanism, the current overlapping length detected by the length detection mechanism is compared with the optimum overlapping length to obtain the length adjustment value, which can be used as the user's operation basis to guide the user to adjust the two belts. After the user adjusts the tightness adjustment mechanism, the actual pressure value detected by the pressure sensor 260 is compared with the optimum pressure value, and the controller judges whether the difference between the two is within the allowable range of error (that is, does not exceed the preset pressure value). Set the pressure difference) to verify whether the tightness of the wearable device is adjusted in place at this time.

Further, the target pressure value includes a test pressure value, and the wearable device is a wrist-worn device. When the wrist-worn device is at the tightness corresponding to the test pressure value, the wrist-worn device can be used to test blood oxygen saturation.

In this embodiment, the wearable device is a wrist-worn device for wearing on the user's wrist, and the wrist-worn device is provided with a blood oxygen detection module for testing the blood oxygen saturation of the user. The blood oxygen detection module is mainly based on Lambert-Beerlaw (Lambert-Beerlaw), according to the principle of different spectral absorption rates of oxygenated hemoglobin and deoxygenated hemoglobin, by using photoplethysmography (PhotoplethysmoGraphy, PPG) Blood oxygen saturation can be derived from the absorption of different wavelengths of light. When testing blood oxygen saturation, wearable devices need to be worn tightly, but not too tightly. When it is so tight that the wrist is squeezed, the optical signal cannot reliably reflect the signs of blood oxygen saturation, which will lead to inaccurate detection results of the blood oxygen detection module.

In this embodiment, after the calibration is completed, the test pressure value that meets the requirements for testing the blood oxygen saturation can be marked. It can be understood that the test pressure value is greater than the optimum pressure value, and it is allowed in the blood oxygen saturation test. Therefore, the test pressure value should be a range value, and it is only necessary to ensure that the measurement result of blood oxygen saturation is within the allowable range of error. When the user needs to test blood oxygen saturation, the controller obtains the cogging 311 corresponding to the test pressure value, and obtains the current cogging 311 fed back by the length detection mechanism and the current pressure value fed back by the pressure sensor 260 to obtain the required adjustment Among them, if the current pressure value is greater than the test pressure value, the user will be prompted to tighten the corresponding cogging 311 number; if the user’s current pressure value is less than the test pressure value, the user will be prompted to loosen the corresponding cogging 311 number . In this way, the wearable device can be adjusted to meet the tightness required by the blood oxygen saturation test, thereby ensuring the accuracy of the detection results of the blood oxygen detection module.
