The invention provides a wearable device.

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

an apparatus main body 100 provided with a controller;

two belt bodies, wherein the belt bodies include a first belt body 200 and a second belt body 300, one end of the first belt body 200 and one end of the second belt body 300 are respectively connected to two ends of the main body 100, and the other ends are used for being connected with each other and enabling the two belt bodies to be partially overlapped;

the tightness adjusting mechanism is arranged on the belt bodies, and can change the overlapping length of the two belt bodies by adjusting the tightness adjusting mechanism so as to adjust the tightness of the wearable equipment; and

and the length detection mechanism is electrically connected with the controller and is used for detecting the overlapping length of the two belt bodies.

It can be understood that the two ends of the belt body are respectively a free end and a fixed end, the fixed end of the belt body is used for connecting with the end of the main body 100 of the device, and the free ends of the two belt bodies are used for connecting with each other, so that the two belt bodies and the main body 100 of the device jointly enclose to form a wearing ring. The size of wearing the circle should adapt to user's head, hand or foot to the elasticity that makes wearable equipment satisfies user's demand, thereby promotes the travelling comfort that the user wore this wearable equipment. Wherein, wearable equipment includes: the wrist watch, the intelligent watch or the intelligent bracelet can be worn on the wrist, the motion monitoring module can be worn on the foot, and the 3D display device can be worn on the head.

In the present invention, the size of the wearing ring can be determined based on the overlapping length detected by the length detection means, and therefore, the optimum overlapping length is determined and the wearing ring is also set to the size with the highest comfort level. Without loss of generality, the wearable device of the present invention can calibrate the optimal overlap length in two ways:

the first way is to determine the wearing ring with the highest comfort for the user according to the circumference of the body part of the user for wearing the wearable device; in the second mode, the wearing ring with the highest comfort degree is determined by the user through self perception when the user wears the wearing ring for the first time. The length detection mechanism detects the overlapping length of the two belts at the time, namely the optimal overlapping length.

The size of wearing the circle can be changed to the overlapping length that changes two areas body, therefore, after confirming the wearing circle that the travelling comfort is the highest, when the user wears wearable equipment, can carry out the coarse adjustment earlier, and make length detection mechanism detect the current overlapping length of two areas body, the difference that current overlapping length and the most suitable overlapping length are length adjustment value, because of length detection mechanism electricity connects in the controller, the controller is through acquireing current overlapping length and the most suitable overlapping length, can acquire length adjustment value and feedback to the user, the user changes the overlapping length of two areas body through adjusting elasticity adjustment mechanism, the regulating variable corresponds to this length adjustment value, can adjust the overlapping length of two areas body to the most suitable overlapping length, wear the circle also can be adjusted to the size that the travelling comfort is the highest. Therefore, the wearable device can adjust the tightness more accurately, and the wearing comfort of a user can be improved.

Referring to fig. 3, in some embodiments, the length detection mechanism includes:

a resistor 320 disposed on the second tape body 300 and electrically connected to the controller;

the guide connector is arranged on the first belt body 200, one end of the guide connector is electrically connected to the controller, and the other end of the guide connector is used for conducting the resistor 320; and

a resistance detection element 110 electrically connected to the controller;

the lead connector is conducted to the resistor 320, and a detection loop is formed among the controller, the resistance detection element 110, the lead connector and the resistor 320;

corresponding to different overlapping lengths of the two belt bodies, the guide connecting pieces are conducted at different positions of the resistance piece 320, so that the resistances of the resistance piece 320 connected to the detection loop are different;

the resistance detecting element 110 detects the resistance of the resistance member 320 connected to the detection loop, so as to represent the overlapping length of the two belts.

Thus, a resistance value of the resistance detection element 110 corresponds to an overlapping length of the two bands, and in the embodiment, the size of the overlapping length is represented by the size of the resistance value, so that the resistance detection element is convenient, fast and accurate, and can provide an accurate basis for adjusting the tightness, thereby ensuring the wearing comfort of the user.

Further, the resistor 320 is disposed in a strip shape extending along the length direction of the second tape body 300, and the lengths of the resistor 320 connected to the detection loop are different corresponding to different overlapping lengths of the first tape body 200 and the second tape body 300.

It is understood that each strip body should have a portion for overlapping another strip body at an end far from the apparatus main body 100, at least the portion of the second strip body 300 should be distributed with the elongated resistive member 320, and the conductive member should be disposed on the portion of the first strip body 200, and the conductive member should be always disposed opposite to the resistive member 320 within an adjustable range of the overlapping length to ensure that the conductive member can be conducted with the resistive member 320, so that the resistance detecting element 110 can always detect a resistance value corresponding to the current overlapping length when the overlapping length of the two strip bodies is changed. Particularly, when the resistive element 320 is configured as a uniform strip structure, the resistance value of the resistive element 320 connected to the detection loop has a linear relationship with the length of the resistive element connected to the detection loop, so that the length adjustment value can be obtained more conveniently.

Of course, the resistance member may also be formed by connecting a plurality of resistance elements in series, and the number of the resistance elements connected to the detection circuit is different corresponding to different overlapping lengths of the two belt bodies, so that the overlapping length of the two belt bodies can also be represented by the resistance value detected by the resistance element.

Referring to fig. 6 to 9, further, the tightness adjusting mechanism includes an adjusting member 210 disposed at an end of the first belt body 200, and a rack structure 310 disposed on the second belt body 300, the adjusting member 210 has an adjusting cavity 211, and at least the rack structure 310 can move in and out of the adjusting cavity 211; the tightness adjusting mechanism further comprises a fastener 220, and the fastener 220 is rotatably arranged in the adjusting cavity 211 to have a first state and a second state; in the first state, the locking member 220 is engaged with the rack structure 310, and drives the adjusting member 210 to move, so as to drive the locking member 220 to move relative to the rack structure 310, and change the length of the rack structure 310 extending into or out of the adjusting cavity 211, so as to increase the length of the second belt body 300 overlapping with the first belt body 200; in the second state, the locking member 220 can be disengaged from the rack structure 310, so that the second strap 300 can move in a direction of withdrawing from the adjusting cavity 211, thereby reducing the length of the second strap 300 overlapping the first strap 200.

In this embodiment, the rack structure 310 includes a plurality of tooth slots 311 disposed at intervals, and after the second belt body 300 is inserted into the adjusting cavity 211, the locking member 220 can be adjusted to the first state, so that the locking member 220 is engaged in one of the tooth slots 311 of the rack structure 310, and the second belt body 300 can be stably connected to the first belt body 200 without external force.

When the overlapping length of the two belts needs to be increased, the user should apply force to the second belt 300 while applying force to drive the adjusting member 210, so that the locking member 220 slides between the plurality of tooth slots 311 of the rack structure 310, and the length of the second belt 300 extending into or out of the adjusting cavity 211 is longer. It can be understood that the longer the second strip 300 extends into the adjustment cavity 211, the longer the overlap length of the two strips before the second strip 300 completely extends into the adjustment cavity 211; after the second band 300 is completely inserted into the adjustment cavity 211, the longer the second band 300 is inserted into the adjustment cavity 211, the longer the two bands are overlapped.

When the overlapping length of the two bands needs to be reduced, the locking member 220 should be adjusted to the second state, so that the locking member 220 is separated from the tooth slot 311 of the rack structure 310, and the second band 300 can be conveniently moved in the direction of withdrawing from the adjusting cavity 211, so as to meet the adjustment requirement of the user.

Without loss of generality, in the embodiment, the adjusting cavity 211 is disposed at 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 adjusting cavity 211, the second belt body 300 can surround the outer side of the first belt body 200, so as to facilitate the force application of a user and improve the convenience of adjusting the tightness of the user. The adjustment member 210 is comprised of two parts fixedly connected by a pin, which together define an adjustment cavity 211. Therefore, other parts of the tightness adjusting mechanism can be firstly installed in one part of the adjusting piece 210, and then the other part of the adjusting piece 210 is fixed, so that the assembly convenience of the tightness adjusting mechanism can be improved. At this time, the adjustment chamber 211 has no other openings except for the inlet and the outlet. Of course, in other embodiments, the adjusting member may be of an integral structure, and may be additionally opened at the side surface to facilitate assembly of other components, and the adjusting cavity may also have other openings except for the inlet and outlet, but only it is required to ensure that the second strap cannot be pulled out of the adjusting cavity from the opening.

Further, the resistive member 320 has at least a portion disposed corresponding to the rack structure 310; the connecting piece is the fastening piece 220, the fastening piece 220 is meshed with the tooth slot 311 and can be conducted to the resistor 320, so that the detection loop is formed among the controller, the resistor 320, the fastening piece 220 and the resistance detection element 110; the fastening member 220 is engaged with different tooth slots 311, can change the overlapping length of the two belt bodies, and can be conducted to different positions of the resistance member 320 to change the resistance of the resistance member 320 connected to the detection circuit, so that the detection value of the resistance detection element 110 corresponds to the current overlapping length.

So, buckle 220 and tooth's socket 311's cooperation, not only can realize wearable equipment's elasticity and adjust, still can insert detection return circuit with resistance piece 320 to ensure that length detection mechanism's testing result can be in step with the accommodation process of elasticity adjustment mechanism, and ensure the accuracy that the elasticity was adjusted. In addition, in the present invention, the adjusting range of the overlapping length of the two belt bodies is determined by the engaging of the locking element 220 with the tooth grooves 311 at the two ends of the rack structure 310, in this embodiment, the material of the locking element 220 is set to be conductive, so that the locking element 220 switches on the resistance element 320, and the length detecting mechanism can detect the overlapping length of the two belt bodies within the adjusting range.

Optionally, a first conductive contact electrically connected to the resistive element 320 is disposed in the tooth slot 311, and the fastening element 220 is engaged with the tooth slot 311 and can be in contact with the first conductive contact. Thus, the latch 220 can be indirectly connected to the resistor 320 by contacting the first conductive contact; optionally, the surface of the resistive element 320 is exposed at the bottom of the slot 311, and the latch element 220 is engaged with the slot 311 and is in contact with the resistive element 320. Thus, the latch 220 can directly conduct to the resistor 320 by contacting the surface of the resistor 320.

Further, when the resistive element 320 is a strip, the resistive element 320 is made of a memory metal material, and the resistive element 320 has a memory state of being arc-shaped in a natural state, so that the second belt body 300 is at least partially arc-shaped naturally. It will be appreciated that the memory metal is super-elastic in that it has a much greater ability to recover from deformation under an external force than a typical metal, i.e., the large strain generated during loading is relieved with unloading and thus returns to a memory shape. In this embodiment, the resistor 320 is made of a memory metal material, which has both conductive capability and deformation recovery capability, so as to prevent the resistor 320 from being deformed to change the relative position with the tooth slot 311, which may result in the situation that the latch 220 cannot be connected to the resistor 320, thereby ensuring the stability of the length detection mechanism.

Referring to fig. 4, in some embodiments, the length detection mechanism includes a color sensor 250 and a plurality of detection portions respectively disposed on the two belt bodies, the color sensor 250 is electrically connected to the controller, and the color of the detection portion identified by the color sensor 250 is used to represent the overlapping length of the two belt bodies.

Specifically, the color sensor 250 is disposed on the first belt 200, the detecting portions are disposed on the second belt 300, and different detecting portions can reflect or emit light rays with different colors for the color sensor 250 to recognize; corresponding to different overlapping lengths of the two belts, different detecting parts are arranged opposite to the color sensor 250, so that the color recognized by the color sensor 250 corresponds to the overlapping length of the two belts, and the overlapping length of the two belts is represented by the color recognized by the color sensor 250.

The color sensor 250 is a small digital sensor, can convert light of red, green and blue components into pulse signals with a certain frequency, does not need an A/D converter and an impedance amplifier, and can directly measure RGB color information of an object to be measured. The color sensor 250 has high reliability in detecting similar colors and hues, and is widely used in colorimetric analysis.

It is understood that the detecting portion should be disposed near the free end of the second belt body 300, and the color sensor 250 should also be disposed near the free end of the first belt body 200, so that the color sensor 250 can be disposed opposite to the detecting portion after the two belt bodies are connected. In the length direction of the second belt body 300, different colors are distributed at different positions of the detection part, and along with the change of the overlapping length of the two belt bodies, the color sensor 250 can recognize different colors with respect to different positions of the detection part, so that one color recognized by the color sensor 250 corresponds to one overlapping length of the two belt bodies, and the overlapping length of the two belt bodies can be represented by the recognition result of the color sensor 250. So, can convenient and fast just accurately provide the basis for adjusting the elasticity equally to ensure user's the travelling comfort of wearing.

Further, the detecting part is provided in plurality, and the detecting parts are distributed at different positions along the length direction of the second belt body 300. Optionally, the detection portions at different positions are coated with UV paints or fluorescent powders with different colors, so that different detection portions can reflect light with different colors for the color sensor 250 to identify; optionally, the detecting portions at different positions are provided with light sources with different colors, so that different detecting portions can emit light with different colors for the color sensor 250 to recognize.

Further, the tooth sockets are the detection portions, and optionally, different tooth sockets 311 are coated with UV paint or fluorescent powder of different colors, so that different tooth sockets 311 can reflect light of different colors; optionally, different light sources with different colors are disposed in different tooth slots 311, so that different tooth slots 311 can emit light with different colors. The color sensor 250 is arranged on the fastener 220, the fastener 220 is engaged with different tooth sockets 311, the overlapping length of the two belt bodies can be changed, 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 fastener 220 is engaged with different tooth sockets 311, the fastener can drive the two belt bodies to move relatively, so that the overlapping lengths of the two belt bodies are different, thereby adjusting the tightness of the wearable device, the color sensor 250 is arranged on the fastener 220, different tooth sockets 311 can reflect or emit light rays with different colors, the color sensor 250 can detect the tooth socket 311 where the fastener 220 is located by identifying the color of the light rays from the tooth socket 311, and the overlapping length of the two belt bodies at the time can be correspondingly obtained. So, buckle 220 and tooth's socket 311's cooperation not only can realize wearable equipment's elasticity and adjust, still can make length detection mechanism detect the overlapping length of two areas of the body to ensure that length detection mechanism's testing result can be in step with elasticity adjustment mechanism's accommodation process, and ensure the accuracy that the elasticity was adjusted, and, still can ensure that length detection mechanism homoenergetic detects the overlapping length of two areas of the body in accommodation range.

Referring to fig. 5, in some embodiments, the length detection mechanism includes a magnet 270 and a hall element 120 electrically connected to the controller, one of the hall element 120 and the magnet 270 is disposed on the second belt 300, and the other is disposed on one of the apparatus main body 100 and the first belt 200;

It can be understood that both ends of the rotating shaft 230 are rotatably connected to the adjusting element 210, and the middle section of the rotating shaft 230 is located in the adjusting cavity 211 for the fixing connection of the locking element 220, so as to improve the rotational stability of the locking element 220. Of course, in other embodiments, two sides of the locking member are respectively provided with a connecting protrusion, and the locking member is rotatably connected to the adjusting member through the two connecting protrusions.

Of course, in other embodiments, an adjusting hole may be formed in the adjusting member, and a user may insert a finger or a bar into the adjusting hole to directly act on the locking member, so that the locking member can be switched between the first state and the second state.

Further, the rack structure 310 includes a plurality of tooth grooves 311 arranged at intervals, the fastener 220 has an engaging end 221, and in the first state, the engaging end 221 is obliquely engaged in the tooth grooves 311;

the tooth slot 311 has a first side a and a second side b opposite to each other, the fastener 220 moves from the first side a of one tooth slot 311 to the adjacent other tooth slot 311, and the overlapping length of the two belts can be increased;

on the first side a, each tooth slot 311 is provided with a guiding inclined surface 312 parallel to the engaging end 221, and the guiding inclined surface 312 is used for guiding the engaging end 221 to enter into another adjacent tooth slot 311 from the first side a.

When the user adjusts the tightness adjusting mechanism to increase the overlapping length of the two bands, the user can fix the adjusting member 210, and then pull the free end of the second band 300 to make the tooth slots 311 of the rack structure 310 sequentially slide through the fastening members 220 until the adjustment is completed. When this wearable equipment was worn in head or foot, can take one hand to fix regulating part 210, the mode of pulling the second area body 300 is adjusted in one hand, when wearable equipment was worn in user's wrist, can support earlier regulating part 210 and press in the desktop, it can to pull the second area body 300 through another hand and adjust.

Further, on the second side b, each of the tooth slots 311 is provided with a limiting surface 313, and the limiting surface 313 and the bottom wall of the tooth slot 311 are arranged at an acute angle or a right angle to limit the engaging end 221 from entering another adjacent tooth slot 311 from the second side b.

It can be understood that, in a natural state of the wearable device, the fit between the first band 200 and the second band 300 is loose for the convenience of wearing by the user, and the fit between the first band 200 and the second band 300 is tight after the wearable device is worn on the human body, thereby causing the second band 300 to have a tendency to be detached from the first band 200. In this embodiment, the second side b of the tooth slot 311 has a limiting surface 313 arranged at an acute angle or a right angle with the bottom wall of the tooth slot 311, so as to limit the engaging end 221 from the second side b to enter into another adjacent tooth slot 311, thereby suppressing the tendency of the second belt body 300 to disengage from the first belt body 200.

Further, the tightness adjusting mechanism further comprises an elastic member, and the elastic member can act on the fastening member 220, so that the fastening member 220 has a tendency to move towards the first state in the second state.

In a natural state of the elastic member, if there is no external force, the locking member 220 can be stably in the first state, so that the locking portion is locked in one of the tooth grooves 311, thereby locking the two belt bodies and ensuring stable connection of the two belt bodies. In addition, when the toggle part 231 is driven to drive the fastener 220 to move to the second state, after the adjustment of the overlapping length of the two belts is completed, the acting force applied to the toggle part 231 is removed, and since the elastic member has a tendency of returning to the natural state, the elastic member can drive the fastener 220 to move in the direction of returning to the first state, so that the fastener 220 can be finally locked in the corresponding tooth slot 311, and the locking of the two belts can be realized again. Certainly, in other embodiments, also can be, the outside of regulating part is equipped with spacing buckle, and when the card of stirring portion was in spacing buckle, the buckle spare was corresponding to be in first state, and at this moment, also can realize the locking to buckle spare.

Further, as shown in fig. 6 to 9, the elastic member is a torsion spring 240 sleeved on the rotating shaft 230, the torsion spring 240 includes a spring body 243, and a first torsion arm 241 and a second torsion arm 242 respectively connected to two ends of the spring body 243, the first torsion arm 241 is fixedly connected to the adjusting member 210, and the second torsion arm 242 is used for abutting against the fastening member 220.

Without loss of generality, in an embodiment of the invention, as shown in fig. 8, when the locking member 220 is in the first state and is engaged in the tooth slot 311 and the torsion spring 240 is in the natural state, a certain gap is formed between the locking member 220 and the second torque arm 242, when the engaging end 221 slides along the guiding inclined surface 312 to the adjacent tooth slot 311, the locking member 220 is biased toward the second torque arm 242 by the reaction force of the guiding inclined surface 312, the biased amount is large enough to be able to abut against the second torque arm 242, and after the engaging end 221 enters the tooth slot 311, the shape of the tooth slot 311 and the shape of the engaging end 221 are matched with each other, the engaging end 221 is engaged in the tooth slot 311, and the locking member 220 can be restored to the first state and is kept a certain distance from the second torque arm 242 of the torsion spring 240 in the natural state. Thus, when the overlapping length of the two bands is increased, the elastic force applied to the locking member 220 is smaller, and the user can pull the second band 300 more easily. When the locking member 220 is in the second state and the torsion spring 240 is reset to the natural state, the locking member 220 cannot be directly driven to the first state, and when the torsion spring 240 is reset to the natural state, the locking member 220 is correspondingly located at a position where the locking member 220 is abutted against the second torsion arm 242 until the locking member 220 is engaged in the tooth slot 311, and the locking member 220 is reset to the first state. Of course, in other embodiments, the latch may abut against the second torsion arm in the first state.

Further, as shown in fig. 8 and 9, two torsion springs 240 are provided, the two torsion springs 240 are respectively provided at two opposite sides of the fastener 220, and the second torsion arms 242 of the two torsion springs 240 are connected to each other to form a whole. The two torsion springs 240 are respectively arranged at the two ends of the fastener 220, so that the fastener 220 is stressed more uniformly, and the two second torsion arms 242 are connected into a whole, so that the second torsion arms 242 are prevented from being deformed due to overlarge acting force of the second torsion arms 242 and the fastener 220.

Furthermore, the wearable device further comprises a tightness sensing piece electrically connected to the controller, wherein the tightness sensing piece is arranged on the wearing side p of the wearable device and used for detecting the tightness of the wearable device. The elasticity sensor can detect the elasticity of wearable equipment, and the elasticity of wearable equipment is simultaneously related with the girth of wearing the size of circle and user wearing position, can embody user's wearing travelling comfort more directly perceivedly. Wear wearable equipment for the first time at the user, be convenient for the user to confirm the size of wearing the circle most suitably, the controller of equipment main part 100 can the prestore have the preset elasticity of suggestion in the human engineering, different position reply should have different most comfortable preset elasticity, adjust the detection result of elasticity adjustment mechanism to elasticity inductor at the user and correspond when this preset elasticity, let the user confirm whether comfortable, if the user feels slightly loose or slightly tight, then can continue the fine setting, until reaching the most suitable elasticity that the user thinks, so, can reduce the work load that the user confirms wearing the circle most suitably greatly.

Further, as shown in fig. 3 to 5, the tightness sensing member is a pressure sensor 260, so that the tightness of the wearable device is represented by a pressure value detected by the pressure sensor 260. Considering that the main body 100 has no flexibility and has poor adhesion to the skin of the human body, the pressure sensor 260 is disposed away from the main body 100, and the detection effect is better, for example, the pressure sensor 260 may be disposed on the wearing side p of the first belt body 200, the second belt body 300, or the adjusting member 210. Without loss of generality, in this embodiment, the pressure sensor 260 is disposed on the wearing side p of the first belt 200 and is disposed close to the adjusting member 210, so that after the user wears the wearable device, the pressure sensor 260 will be located between the skin of the human body and the first belt 200, and thus can sense the pressure of interaction between the skin of the human body and the first belt 200, it can be understood that this pressure value is closely related to the tightness of the wearable device, and the larger the pressure value is, the tighter the wearable device is worn on the human body, and thus, the pressure value detected by the pressure sensor 260 represents the tightness of the wearable device. Of course, in other embodiments, the tightness sensor may also be a friction sensor, and the friction sensor detects the friction between the band and the skin of the human body by slightly rotating the wearable device relative to the wearing part of the human body, so as to represent the tightness of the wearable device.

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

When a user wears the wearable device for the first time, tightness calibration can be performed on different tooth sockets 311, the buckle piece 220 is firstly meshed in the tooth socket 311 closest to the free end of the second belt body 300, the size of the wearing ring is the largest at the moment, and then the plurality of tooth sockets 311 sequentially pass through the buckle piece 220 by pulling the second belt body 300 until the two belt bodies cannot be tightened again or the buckle piece 220 reaches the tooth socket 311 farthest from the free end of the second belt body 300. In this process, the length detection mechanism sequentially feeds back detection values (such as resistance values, colors, or hall voltages) corresponding to the overlapping length of the two belts to the controller, and the pressure sensor 260 sequentially feeds back pressure values to the controller, and the controller stores the detection values and the pressure values corresponding to each of the tooth grooves 311. When a user needs to reach a certain target pressure value, the controller can call a detection value corresponding to the target pressure value to determine the tooth socket 311 that the buckling piece 220 needs to reach, at this moment, the length detection mechanism detects the tooth socket 311 where the current buckling piece 220 is located, and after receiving the information, the controller can give an adjustment instruction, wherein the adjustment instruction comprises loosening or tightening and the specific number of the adjusted tooth sockets 311. It can be understood that the target pressure value comprises an optimal pressure value corresponding to the optimal tightness, the target overlapping length at the moment is also the optimal overlapping length, the user can mark the optimal pressure value, when the device is worn daily, the controller feeds the optimal pressure value back to the user after calling the overlapping length corresponding to the optimal pressure value, and the user can conveniently adjust the overlapping length of the two belt bodies to the optimal overlapping length by adjusting the tightness adjusting mechanism.

Further, the pressure sensor 260 is further configured to detect an actual pressure value after the overlapping length of the two belt bodies is adjusted to a target overlapping length, and the controller obtains the actual pressure value and determines whether a difference between the actual pressure value and the target pressure value is smaller than or equal to a preset pressure difference. As such, the actual pressure value detected by the pressure sensor 260 may provide another accurate basis for tightness adjustment of the wearable device. Before the user adjusts the tightness adjusting mechanism, the current overlapping length detected by the length detecting mechanism is compared with the optimal overlapping length to obtain a length adjusting value, the length adjusting value can be used as an operation basis of the user to guide the user to adjust the overlapping length of the two belt bodies, after the user adjusts the tightness adjusting mechanism, an actual pressure value detected by the pressure sensor 260 is compared with the optimal pressure value, and whether the difference value of the actual pressure value and the optimal pressure value is within an error allowable range (namely not more than a preset pressure difference value) is judged through the controller so as to verify whether the tightness of the wearable equipment is adjusted in place at the moment.

Further, the target pressure value comprises a test pressure value, the wearable device is a wrist-worn device, and when the wrist-worn device is in the tightness corresponding to the test pressure value, the wrist-worn device can be used for testing the blood oxygen saturation.

In this embodiment, the wearable device is a wrist-worn device for wearing on a wrist of a user, and the wrist-worn device is provided with a blood oxygen detection module for testing a blood oxygen saturation level of the user. The blood oxygen detection module is mainly based on Lambert-beer law, and derives the blood oxygen saturation degree by measuring the absorption amount of blood to light rays with two different wavelengths by utilizing a PhotoPlethysmoGraphy (PPG) technology according to the principle that the spectral absorption rates of oxyhemoglobin and deoxyhemoglobin are different. When testing oxyhemoglobin saturation, wearable equipment need be worn to the unbalance, but can not the tension, can understand, when blood oxygen detection module and wrist laminating are more loose, and have the gap between the skin with the wrist, perhaps when laminating too tight so that cause the extrusion to the wrist, light signal can not reliably reflect oxyhemoglobin saturation sign, will lead to the inaccurate detection result of blood oxygen detection module.

In this embodiment, after the calibration is completed, the test pressure value meeting the requirement of testing the blood oxygen saturation can be marked, and it can be understood that the test pressure value is greater than the optimal pressure value, and a certain error is allowed in the test of the blood oxygen saturation, so that the test pressure value should be a range value, and only the measurement result of the blood oxygen saturation needs to be ensured to be within the error allowable range. When the user needs to test the blood oxygen saturation, the controller obtains the tooth socket 311 corresponding to the test pressure value, obtains the current tooth socket 311 where the length detection mechanism is located and the current pressure value fed back by the pressure sensor 260 to obtain the number of the tooth sockets 311 needing to be adjusted, prompts the user to tighten the corresponding number of the tooth sockets 311 if the current pressure value is larger than the test pressure value, and prompts the user to loosen the corresponding number of the tooth sockets 311 if the current pressure value is smaller than the test pressure value. Therefore, the wearable device can be adjusted to the tightness meeting the requirement of the blood oxygen saturation test, and the accuracy of the detection result of the blood oxygen detection module is ensured.
