According to one embodiment of the present invention, a wearable device is provided. The wearable device may be, but is not limited to, VR devices, AR devices, smart watches, headphones, smart glasses, exoskeletons, etc., and may also be an auxiliary therapeutic device, such as a respiratory mask, etc.

As shown in fig. 1-3, the wearable device includes a body portion, a strap, and a tightening device. The main body part is the main functional part of the device. For example, the main body portion includes a power supply, a display module 18, a data processing module, a control module, an optical module, an acoustic module, a communication module, and other functional systems. The function of the main body part can be set by a person skilled in the art according to actual needs. Taking VR equipment as an example, the main body part can realize digital information processing such as audio and video of VR equipment, virtual scene display, sound output, position and motion capture, and the like, and can also perform external information interaction.

In this example, as shown in fig. 3, the main body portion includes a master member 11 and a slave member 12. For example, the main part 11 includes a first front assembly 17, a first rear assembly 19, a display module 18, a first electronic module 20, and the like. The first front assembly 17 and the first rear assembly 19 are connected together to form a cavity therein. The display module 18 and the first electronic module 20 etc. are arranged in the cavity. For example, display module 18 includes a display screen. The first electronic module 20 includes a control module, a processing module, a storage module, a communication transmission module, a sound module, and the like.

The slave component 12 includes a second front assembly 32, a second rear assembly 33, a second electronic module 31, and the like. The second front assembly 32 and the second rear assembly 33 are connected together to form a cavity therein. A second electronic module 31 or the like is arranged in the cavity. The second electronic module 31 includes a power module, a communication transmission module, and the like.

The connection manner of the above modules is common knowledge in the art, and will not be described in detail here.

As shown in fig. 1-2, the master 11 and slave 12 are connected by a strap. For example, the strap is made of flexible materials such as plastic, rubber, silica gel, cloth, etc. so that the strap can be wound. The cross section of the binding band can be flat, round, oval, etc.

Taking VR equipment as an example, the straps include a top strap 13 at the top of the equipment and side straps 14 at the sides of the equipment.

As shown in fig. 2, a wire 15 is embedded in the strap. The master component 11 and the slave component 12 are electrically connected by a wire 15. The master 11 and slave 12 are powered or data transmitted via wires 15. For example, a wire hole in the extending direction is provided in the strap. The wire 15 is disposed in the wire hole.

It is also possible to injection mold the wire 15 into the strap by means of insert molding.

The strap may also be woven from fibrous material. The strap wires 15 are woven into the strap.

A tightening device is provided in at least one of the master part 11 and the slave part 12. For example, as shown in fig. 2, a tightening device is provided in the main member 11.

The tightening device comprises a rotating shaft and an auxiliary winding mechanism 16. The rotating shaft is rotatably connected with the main body. One end of the binding belt is connected with the rotating shaft. In this example, as shown in fig. 1 or 3, a hole 41 is provided in the first front assembly 17. As shown in fig. 6, one end of the top strap 13 is threaded into the cavity of the main part 11 from the hole 41 and is connected to the shaft. One end of the wire 15 is connected to the first electronic module 20. The auxiliary winding mechanism 16 is configured to rotate the shaft so that the strap can be wound around or released from the shaft. As shown in fig. 7, the other end of the top strap 13 penetrates into the cavity of the secondary member 12. The other end of the wire 15 is connected to a second electronic module 31.

The tightening device is capable of adjusting the effective length of the strap. For example, when the rotary shaft rotates counterclockwise as viewed from the right side, the strap is wound around the rotary shaft, thereby shortening the effective length of the strap; when rotated clockwise, the strap is released from the shaft, thereby extending the effective length of the strap. The effective length refers to the length of the portion of the strap that is intended to fit the human body.

In other examples, one end of side strap 14 is connected to a rotating shaft. The tightening device is capable of adjusting the effective length of side straps 14.

In an embodiment of the invention, the wearable device comprises a built-in tightening means. The binding band is connected with the tightening device. The tightening device can enable the binding belt to be wound on the rotating shaft so as to shorten the effective length; and enables the strap to be released from the shaft to increase the effective length. The operation of pulling and retracting the binding belt is very easy.

Furthermore, the wires 15 are embedded in the strap, which, on the one hand, saves space; on the other hand, the wiring of the wire 15 is easy, and the wire 15 is not easily damaged by external objects, so that the reliability of the wearable device is improved.

Further, the main body portion includes a master component 11 and a slave component 12. The split type setting mode enables the weight of the main body part to be distributed effectively, and discomfort in wearing caused by weight concentration is avoided.

In one example, as shown in fig. 4 and 6, the inside of the rotating shaft is provided with a wiring hole 30. The routing holes 30 are used for routing the wires 15. The opening of the wiring hole 30 is located on the end face of the rotating shaft. After being led out from the strap, the lead 15 passes through the wiring hole 30 and is led out from the mouth to reach the main body. For example, the trace hole 30 penetrates through both ends of the rotating shaft in the axial direction or the trace hole 30 has one open end. After being led out from the binding band, the multi-strand wire 15 passes through the wire hole 30 and passes out from the mouth. Finally reaches the main part 11 and is connected to the first electronic module 20.

The arrangement of the wiring holes 30 enables the wires 15 to be arranged in the rotating shaft, so that other space is not occupied, mutual interference between the wires 15 and other components is avoided, and reliability is improved.

It should be noted that, during the winding and releasing process of the binding band, the drawn wire 15 or the stranded wire 15 may be distorted to adapt to the rotation of the binding band rotating shaft.

Preferably, the wire 15 is arranged coaxially with the rotation axis. Thus, the deformation of the wire 15 in the process of stretching the binding belt is small, and the wire is not easy to damage.

In one example, as shown in fig. 4, the shaft includes a body portion 21 and a detachable portion 23. The body portion 21 includes an opening at the side portion and communicating with the routing hole 30. The detachable portion 23 is covered on the opening. One end of the strap is clamped between the body portion 21 and the detachable portion 23.

For example, the body portion 21 and the detaching portion 23 each have an arc-shaped structure. The dimensions of the arcuate structure may be set by those skilled in the art as desired. The body portion 21 and the detachable portion 23 are connected together by a screw 28 to form a cylindrical rotation shaft, for example, a cylindrical shape, a square cylindrical shape, an elliptical cylindrical shape, or the like.

When the lead 15 is mounted, the dismounting portion 23 is first removed; placing the part of the lead 15 from which the binding band is led into the wiring hole 30; the detachable portion 23 is then fitted over the opening, and one end of the strap is clamped between the body portion 21 and the detachable portion 23.

The shaft is provided in a detachable manner so that the installation of the wire 15 is easy.

In addition, the strap is clamped between the detaching portion 23 and the body portion 21, so that the connection strength of the strap and the rotation shaft is higher, and the installation is easier.

In addition, the bandage is detachably connected with the rotating shaft, so that the replacement of parts of the wearable device is easy.

Preferably, as shown in fig. 4, a protrusion 29 is provided on the outer surface of the body portion 21 or the detachable portion 23. For example, the projection 29 has a cylindrical shape. Grooves are arranged on the binding bands. The grooves may be through grooves or non-through grooves. The projection 29 snaps into the recess to form a snap fit. The mode of joint makes the bandage more firm with the connection of pivot.

In addition, the mode of joint can prevent to appear skidding between bandage and the pivot.

Further, the stud bumps 29 are plural. The binding band is in a flat structure. A plurality of grooves are provided on the strap. The plurality of protrusions 29 are respectively caught in the plurality of grooves, which makes the connection strength of the strap with the rotation shaft higher.

Further, as shown in fig. 3-4, a tab 37 is provided on the strap. The tab 37 is located within the body portion (e.g., the master 11 or slave 12). The local dimensions of the lugs 37 are greater than the local dimensions of the holes 41 so that the holes 41 can form stops for the lugs 37, which can define the maximum release length of the strap, preventing the wire 15 from being broken by excessive release of the strap.

In one example, as shown in fig. 3-4, the auxiliary winding mechanism 16 includes a resilient torsion element. One end of the elastic torsion element is connected with the rotating shaft, and the other end of the elastic torsion element is fixed with the main body part. For example, the other end of the elastic torsion element is fixed directly in the main part 11 or the secondary part 12; the fixing may be formed indirectly with the master member 11 or the slave member 12 through other connectors, for example, a protective cover 24 described below.

In this example, the elastic torsion element has a set torsion force to drive the rotation shaft to rotate. For example, when the strap is wound, the elastic torsion element is twisted to create a set restoring force; when the binding band is released, the elastic torsion element returns to the original position under the action of a restoring force.

Alternatively, the elastic torsion element is twisted when the strap is released; when the strap is wound, the elastic torsion element returns to the original position.

The elastic torsion element facilitates the winding and releasing operations of the strap by simply pulling and pushing the strap.

In other examples, the body portion further includes a damping element (not shown). The damping element is used to create friction against the strap to fix the effective length of the strap.

Alternatively, as shown in fig. 3, 4, and 6, the elastic torsion member includes at least one of a spring 22 and a torsion spring. The elastic torsion element is sleeved on the rotating shaft and is mutually independent with the binding belt. Mutually independent means that the two are separated and not contacted with each other. For example, the band is wound in juxtaposition with the spring 22, separated by a separator. In this way, no interference with the spring 22 occurs during winding and unwinding of the strap.

In addition, the volume of the spring 22 and the torsion spring is small, and the space occupied by the spring and the torsion spring sleeved on the rotating shaft is small.

In one example, as shown in fig. 3, 4, and 6, the auxiliary winding mechanism 16 further includes a protective cover 24. The protective cover 24 covers the outside of the elastic torsion element. One end of the elastic torsion element is clamped with the rotating shaft, the other end of the elastic torsion element is clamped with the protective cover 24, and the protective cover 24 is connected with the main body. The protective cover 24 is capable of effectively protecting the elastic torsion element.

Preferably, as shown in fig. 5, the protective cover 24 includes a cylindrical portion 34 and an end portion 35 provided at one end of the cylindrical portion 34. The middle of the end 35 has a through hole 26. The elastic torsion element is provided in the cylindrical portion 34. The structure of the protective cover 24 facilitates the installation of the spring 22. The cylindrical portion 34 is provided with a notch 25 for engaging the elastic torsion element. One end of the rotating shaft passes through the through hole 26. A through-hole 27 is also provided at the end 35.

For example, as shown in fig. 5-6, the entirety of the protective cover 24 is circular in configuration. The protective cover 24 is fixed in the main part 11, and the outer surface of the protective cover 24 is provided with a boss 36. The main part 11 comprises a stop cooperating with the boss 36. The stop forms a stop for boss 36 to prevent rotation of protective cover 24 relative to main component 11.

The outer end of the spring 22 forms a hook-like structure. The hook-like structure hooks into the notch 25 to form a snap fit. The inner end of the spring 22 also forms a hook-like structure. The hook-like structure is hooked at the edge of the body portion 21 or the detachable portion 23. One end of the rotating shaft sleeved with the spring 22 passes through the through hole 26. The rotation shaft rotates around the through hole 26 and is restrained in the through hole 26.

The end 35 is provided with a through hole 27. The through hole 27 communicates with the inside of the tube. The through hole 27 serves as a viewing hole. At the time of installation, the user can observe the relative position of the spring 22 through the through hole 27 to facilitate the installation of the spring 22.

Further, the user protrudes into the installation tool through the through hole 27 to compress the spring 22, thereby facilitating installation into the cylindrical portion 34.

Optionally, the protective cover 24 is integrally formed. For example, the protective cover 24 is made of plastic, metal, or the like, and is integrally molded by injection molding, stamping, or the like.

In one example, the auxiliary winding mechanism 16 includes a rotary motor (not shown). The rotary motor is disposed within the body portion. The driving shaft of the rotary motor is connected with the rotating shaft. For example, the rotary motor is an electric motor. The motor drives the rotating shaft to rotate, so that the binding belt is wound or released. The rotary motor realizes automatic winding and releasing of the binding band.

Preferably, the auxiliary winding mechanism 16 further comprises sensing means (not shown). The sensing device is disposed at the body portion. The sensing device is configured to sense at least one of a length and a tension of the strap.

For example, the sensing means comprises a tension sensor or a position sensor. The sensing means are arranged in the main part 11 together with the tightening means. The tightening means releases or winds the strap when the VR device is worn by the user. The tension sensor senses strap tension. The strap is adjusted to a suitable length according to the condition of the user's head, while the tension of the strap reaches a set value. At this time, the motor stops rotating.

Alternatively, the position sensor senses that the size of the strap is adjusted to a proper range and the motor stops rotating. The person skilled in the art can set the tension, the size range according to the actual need.

In this example, when wearing wearable equipment, need not the user to take turns to, wearable equipment just can automatically regulated bandage length, has promoted user's experience and has felt greatly.

In one example, as shown in fig. 8, the auxiliary winding mechanism 16 includes a cylinder 38 and a piston portion 39 slidably connected to the cylinder 38. The cylinder 38 is provided in a main body portion, for example, the master member 11 or the slave member 12. An energy storage liquid or gas is disposed within the cylinder 38. For example, the energy storage liquid is hydraulic oil. The energy storage gas is nitrogen or inert gas, etc. The piston portion 39 is connected to the rotary shaft through a swing link 40. One end of the swing link 40 is fixedly connected to the rotating shaft, and the other end is hinged to the piston portion 39. The cylinder 38 drives the rotation shaft to rotate by the piston portion 39.

For example, when the strap is wound, the shaft rotates and drives the swing link 40 to swing. The swing link 40 pushes the piston portion 39 to compress the stored energy liquid or gas in the cylinder 38 for energy storage. Upon release of the strap, the volume of stored energy liquid or gas expands, pushing the piston portion 39 in a reverse direction. The piston part 39 pushes the swing rod 40 to swing, and the swing rod 40 drives the rotating shaft to reversely rotate, so that the binding belt is released.

In one example, the auxiliary winding mechanism 16 includes a crank (not shown). The rocking handle is connected with one end of the rotating shaft. The crank is embedded in the body portion. When the binding belt is required to be released, a user shakes the rocking handle, so that the rotating shaft is driven to rotate, and the effective length of the binding belt is increased; when the length of the binding band needs to be shortened, the user reversely shakes the rocking handle, so that the rotating shaft is driven to reversely rotate, and the effective length of the binding band is reduced.

Of course, the auxiliary winding mechanism 16 is not limited to the above-described embodiment, and may be set by those skilled in the art according to actual needs.

While certain specific embodiments of the invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
