Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

One embodiment of a wearable electronic device according to the present application, as shown in fig. 1, includes a device body 100.

The infrared sensor is used to detect a wearing state (i.e., worn or not worn) of the wearable electronic device. The infrared sensor 300 is disposed toward the inside of the apparatus body 100 or the endless belt 200.

The control circuit board can judge the state of the wearable electronic equipment according to the detection signal of the infrared sensor and make corresponding control.

As shown in FIG. 3, a shape memory alloy 400 is disposed within the annular band 200. Alternatively, the shape memory alloy 400 may be a material composed of two or more metal elements having a shape memory effect by thermo-elastic and martensitic transformation and inversion thereof. As an example of the present application, a shape memory alloy may be a titanium-nickel alloy. The shape memory alloy 400 is embedded inside the annular band 200. Optionally, the shape memory alloy is not exposed from the surface of the endless belt. When the user uses, the annular area of being made by elastic material directly contacts with the user, improves wearing formula electronic equipment's aesthetic property and travelling comfort. When the shape memory alloy is deformed, the annular belt can be driven to deform, and the effect of tightening or loosening is realized. Alternatively, the shape memory alloy 400 may extend along the length of the annular band 200.

The shape memory alloy 400 disposed within the endless belt 200 is electrically connected to a control circuit board, which may supply power to the shape memory alloy 400. The shape memory alloy 400 of the present application has an extended state and a contracted state depending on the characteristics of the shape memory alloy. FIG. 3 illustrates an extended state and a contracted state of a shape memory alloy 400 according to an embodiment of the present application. The length of the annular band 200 is longer when the shape memory alloy 400 is in the expanded state, and the length of the annular band 200 is shorter when the shape memory alloy 400 is in the contracted state.

The application provides a wearing principle of wearing formula electronic equipment is: in a state where the ring band 200 is not worn around the user, the infrared sensor 300 does not detect the reflected infrared ray, which represents that the wearable electronic device is not worn by the user; the control circuit board disconnects the power supply path to the shape memory alloy 400, and the shape memory alloy is in the extended state; in a state where the ring band 200 is worn around the user, the infrared sensor 300 can detect infrared rays reflected back by the user, which represents that the wearable electronic device is in a wearing state; the infrared sensor 300 transmits the detection signal to the control circuit board, and the control circuit board supplies power to the shape memory alloy 400; the shape memory alloy is conducted and heated, the stretching state is changed into the shrinking state, the shape memory alloy drives the annular belt 200 to shrink and deform, the inner diameter of the annular belt 200 is reduced, and a user wears the wearable electronic device. The shape memory alloy 400 is preferably capable of being deformed in a contraction along its length to better lock the inner diameter of the annular band 200.

In the embodiment of the application, the shape memory alloy 400 is arranged in the annular belt 200 which can generate deformation, and the control circuit board is used for supplying power and heating to the shape memory alloy, so that the annular belt is subjected to contraction and relaxation deformation. This application can realize that the consumer is when wearing wearable electronic equipment, and the annular band 200 is fixed in on one's body the consumer through shrink deformation, and the wearing mode is simple and convenient, need not complicated wearing operation, improves and uses experience. The application provides a wearing formula electronic equipment mode of wearing is novel, simple structure.

As an optional embodiment of the present application, the wearable electronic device further includes a pressure sensor 500, and the pressure sensor is electrically connected to the control circuit board to implement signal transmission between the two. The pressure sensor 500 is used for detecting the pressure to which the wearable electronic device is subjected. For example, for detecting a pressure to which at least one of the endless belt and the apparatus main body is subjected. Under the condition that the shape memory alloy 400 is in the contraction state, the control circuit board detects the pressure applied to the wearable electronic device through the pressure sensor 500, and under the condition that the detected pressure reaches a preset pressure threshold value, the control circuit board adjusts the power supply current for the shape memory alloy 400, so that the annular band 200 is kept at the current contraction deformation amount.

This embodiment is through configuration pressure sensor on electronic equipment, judges the wearing pressure that the wearable electronic equipment produced by the annular belt shrink when wearing on the user, also promptly wears the elasticity degree. The pressure experienced by the electronic device is representative of the degree of tightness with which the electronic device is worn by the user. The embodiment can adapt to the physical characteristics of different users according to the detected pressure, and the situation that the contraction is too tight or too loose is avoided. An appropriate preset pressure threshold value representing an appropriate degree of tightness of wear may be set in the electronic device.

The preset pressure threshold value can be a fixed value preset in the control circuit board, and can also be configured into a form capable of being freely set on the equipment main body, and a user can adjust the degree of tightness according to the preference of the user. This is not limited by the present application. When the preset pressure threshold is a fixed value, the preset pressure threshold can be directly set by a manufacturer. When the preset pressure threshold is adjustable, the user can set according to the wearing elasticity preference. The shrinkage deformation of the annular band is adjusted by comparing the pressure detection result of the pressure sensor with the preset pressure threshold, so that the wearing process of a user is further simplified, and the influence caused by different wearing positions of different users in different thicknesses is overcome. The degree of tightness of wearing can be set by a user more flexibly by the design mode, so that the use of a customer is facilitated, and the wearing comfort level is improved.

Optionally, the pressure sensor 500 of the wearable electronic device is disposed within the endless belt 200. The mounting structure of the pressure sensor 500 on the endless belt 200 is shown in fig. 2. The annular belt has deformability, and the pressure sensor is arranged in the annular belt, so that the pressure detection function is realized more easily, and the pressure sensor is not easy to generate oppression and cushion placing feeling for a user. By utilizing the characteristic that the annular belt can generate deformation, under the condition that the annular belt generates pressure with a human body, the annular belt can be compressed and deformed with the human body, and the pressure is directly transmitted to the pressure sensor. In addition, the aesthetic appearance of the endless belt can be improved. Alternatively, the pressure sensor may be disposed on the surface of the endless belt to improve the sensitivity of pressure detection. The application can also choose to arrange the pressure sensor at other positions. For example, a pressure sensor may be provided directly inside the apparatus main body.

As an example of the present application, in the case that the shape memory alloy 400 is in the contracted state, the control circuit board can end the power supply to the shape memory alloy, the shape memory alloy 400 changes from the contracted state to the extended state, and the shape memory alloy brings the endless belt 200 to extend. The user can remove the wearable electronic equipment through the design mode. The mode of removing and finishing wearing is convenient for users to use, and the use convenience is improved. The ablation principle of this embodiment is: when the user needs to remove the wearable electronic device, the user can selectively remove the wearable electronic device through the control button, the virtual control switch and the like, the control circuit board can stop the power supply path to the shape memory alloy 400, the shape memory alloy is gradually changed from the contraction state to the extension state at the moment, the annular size of the annular belt 200 is prolonged, and the user can directly remove the wearable electronic device. The power supply to the shape memory alloy 400 is stopped through the control circuit board, the annular size of the annular belt 200 is increased, a user can conveniently remove the wearable electronic device, the removing process is simplified, and the user experience is optimized.

As an alternative embodiment of the present application, the endless belt 200 may be formed by a strip-shaped band in a loop-shaped manner by bending, that is, the endless belt has two ends that are not connected to each other. In the assembling process of the wearable electronic device, two ends of the strip-shaped binding band are respectively and fixedly connected to the device main body 100, and the annular band and the device main body form a complete closed ring. The shape memory alloy is electrically connected with a control circuit board in the device main body through two ends of the annular belt. The annular belt is set into the strip-shaped binding belt, so that on one hand, the material consumption of the annular belt can be reduced, and the cost is reduced; on the other hand, the shape memory alloy in the annular belt is convenient to form electric connection with the device body, and the shape memory alloy can be connected to the device body together with the annular belt through two ends of the annular belt.

Alternatively, as another embodiment, the annular band 200 itself may be a complete annular band. That is, the endless belt is an integrally formed endless structure. When the wearable electronic device is assembled, at least a part of the endless belt 200 is fixedly connected to the device main body 100. For example, the endless belt 200 may pass through the apparatus body 100, and a portion passing through the apparatus body 100 forms a fixed connection with the apparatus body 100. Alternatively, the device body may comprise separable lower and upper shells that snap together to sandwich a length of the endless belt therebetween. The shape memory alloy in the endless belt is extended from a portion of the endless belt sandwiched by the apparatus main body, and is electrically connected to the control circuit board.

In an alternative embodiment, the device body 100 has a snap feature thereon to which a portion of the annular band 200 is snap-fit secured.

The annular belt is set to be a complete annular belt, so that the attractiveness of the wearable electronic equipment can be benefited, the connection strength between the annular belt and the equipment main body can be obviously improved, and the connection reliability is guaranteed.

As an alternative embodiment of the present application, as shown in fig. 1, the outer surface 202 of the annular belt has protrusions 2021 and depressions 2022, and the protrusions 2021 and the depressions 2022 are distributed at intervals to form a concavo-convex structured surface. Optionally, the protrusions 2021 and depressions 2022 are uniformly distributed on the outer surface 202 of the annular band. The line of the interval between the protrusion 2021 and the recess 2022 arranged on the outer surface 202 of the annular belt can play a good appearance decoration role for the annular belt 200, and is beneficial to the expansion and contraction deformation of the annular belt.

Alternatively, the protrusions 2021 and the depressions 2022 may be made to constitute a rack-like textured surface. Alternatively, the rack-like textured protrusions 2021 are distributed side by side along the length of the endless belt 200. The protrusions with the rack-shaped grains are distributed side by side along the length direction of the annular belt, so that elastic expansion of the annular belt 200 is facilitated, deformation resistance of the shape memory alloy 400 during transition of two states of expansion and contraction deformation is reduced, energy loss is reduced, and meanwhile, the protrusions distributed side by side can improve the design attractiveness of the annular belt 200. Alternatively, the protrusions and depressions may also form a scale-like relief structure surface.

As an alternative embodiment of the present application, as shown in FIG. 1, the inner surface 201 of the annular band is a flat surface. I.e. the roughness of the inner surface of the endless belt is small. The surface condition can reduce the friction between the inner surface 201 of the annular belt and the skin or clothes of a user, is beneficial to improving the wearing comfort of the user, and improves the user experience.

As an alternative embodiment of the present application, the annular band 200 is made of an elastic material, so as to be more easily elastically deformed to extend and contract, and is convenient to wear on the user, and plays a role in fixing the wearable electronic device on the user. Particularly, the elastic material is applied to the annular belt, and the annular belt has better deformability by combining the convex and concave structural characteristics, so that the annular belt is more convenient to wear and comfortable to wear.

Alternatively, the present application may also use a device having mechanical deformation capability to construct the endless belt. The annular belt can realize the deformation capacity of extension and contraction through an internal mechanical device. This application does not exclude such embodiments. In the embodiment of using the endless belt having the mechanical deformation characteristic or using the endless belt made of the inelastic material, the technical features of forming the protrusions and the recesses on the endless belt may be also used to improve the smoothness of deformation of the endless belt and reduce the risk of failure of the mechanical structure of the endless belt.

Alternatively, the endless belt 200 is made of a silicone rubber material. Since silicone rubber has excellent insulation properties, it is used to form an endless belt, and the safety of the endless belt 200 is high in the case where the shape memory alloy 400 can be electrically conducted. Meanwhile, the gas permeability of the silicon rubber is good, and the manufactured annular belt 200 has good gas permeability, so that the wearing comfort of a user is effectively improved. In addition, the silicon rubber is non-toxic, tasteless and odorless, and the safety of the wearable electronic product can be guaranteed by manufacturing the annular belt 200 from the silicon rubber.

As an alternative embodiment of the present application, as shown in FIG. 3, the shape memory alloy 400 extends in a sinusoidal wave pattern along the length of the endless belt 200. Alternatively, shape memory alloy 400 may extend in the form of an angular wave along the length of annular band 200. An advantage of this embodiment is that the shape memory alloy that is bent to extend along the length of the endless belt is able to deform to a greater extent in the length direction of the endless belt, while the deformation in the width direction is very small. Thus, the endless belt can be more effectively expressed as being elongated and shortened, and the change in the width direction is almost negligible. The comfort and the aesthetic degree are optimized when the mask is applied. Those skilled in the art will appreciate that the shape memory alloy 400 may be provided in other forms, as long as the probability of breakage during the expansion of the shape memory alloy is reduced.

As an embodiment of the present application, the wearable electronic device is a wristwatch. The annular band of watch is fixed in on the consumer through shrink deformation, and the wearing mode is simple, need not complicated wearing operation, is favorable to optimizing and uses the experience. Of course, the wearable electronic device of the present application may also be a bracelet or other electronic device, and the present application does not limit this.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
