Description

Technical Field

[0001] The present invention relates to the field of systems and methods for charging wearable electronic devices.

Background Art

[0002] A wearable electronic device is a smart electronic device (an electronic device equipped with a microcontroller) worn on the surface of the skin, which can detect, analyze, transmit information on biological signals such as vital signs and / or ambient data, and provide immediate feedback to the wearer.

[0003] With the progress of wearable electronic devices, many function-oriented devices such as smartwatches or smart wristbands with functions such as global positioning system (GPS), heart rate detection, and pace counting are becoming increasingly popular among consumers. However, these devices tend to consume a significant amount of power.

[0004] Due to the limited size of wearable electronic devices, the capacity of the battery installed therein cannot be increased, thereby forcing the user to charge the electronic device more frequently.

[0005] Therefore, in the art, there is a need for a new wearable electronic device charging unit.

[0077] First, as shown in the schematic diagram in Figure 1, a wearable electronic device, such as a wearable electronic device 100 (e.g., a smartwatch, pulse watch, fitness tracker, watch phone, etc.), may consist of a wearable electronic device case 102 and a wearable electronic device strap 104.

[0078] The wearable electronic device case 102 may include (i) a cavity 106 for housing a battery, for example, a rechargeable battery (not shown); (ii) at least one electrical connector or wireless charging mechanism, for example, an electrical connector 108 located on one of the surfaces of the wearable electronic device case (e.g., bottom surface 110, side surface 111, etc.); and (iii) at least one power-consuming component, for example, sensors 112a-112c located on one or more of the surfaces of the wearable electronic device case (e.g., bottom surface 110). The electrical connector 108 can enable the formation of electrical interactions of the rechargeable battery housed in the cavity 106, while the sensors 112a-112c (which may be any one of an accelerometer, ambient temperature sensor, gyroscope, etc.) can provide the wearable electronic device case 102 with information about measurable characteristics related to the user of the wearable electronic device 100 (e.g., pulse rate, body temperature, blood pressure, etc.).

[0079] The wearable electronic device strap 104 may consist of one or more strap sections, for example, strap sections 104a to 104b, and the strap sections are attached to the wearable electronic device case 102 from opposite directions by at least one of their ends. The strap sections 104a to 104b can be made of various materials, such as leather, plastic, rubber, or cloth, and can be fastened and secured to each other around a designated part of the user's body, for example, around the user's wrist, using any fastening means known in the art (e.g., hook-and-loop fasteners, snap fasteners, buckles, etc.).

[0080] As an example, the wearable electronic device 100 is a smartwatch having a circular case 102, one end of which is connected to a first leather strap portion 104a and the other end of which is connected to a second leather strap portion 104b. The first leather strap portion 104a includes a buckle 114 having prongs 115, while the second leather strap portion 104b includes a plurality of equally spaced holes oriented to receive the prongs 115.

[0081] To fasten the wearable electronic device 100 around the user's wrist, the wearable electronic device case 102 is positioned at the upper end of the user's wrist such that its bottom surface 110 is in contact with the user's wrist, while a portion of the second leather strap 104b, which includes several of the holes, passes through the buckle 114. Following this action, the prong 115 is inserted through one of the holes, and as a result, both strap portions 104a-104b are fastened together and wrap around the user's wrist.

[0082] With this in mind, we will focus on Figures 2A to 2D, which show schematic diagrams of the wearable electronic device charging unit according to the subject matter of this disclosure and its operation when fastened to the wearable electronic device strap 104.

[0083] As shown in the schematic diagram of Figure 2A, the wearable electronic device charging unit 116 includes (i) a power source, for example, a power supply 118, and (ii) at least one fixed element, for example, a fixed element 120 coupled to the power supply 118.

[0084] The fastening element 120 may include any fastening means known in the art (e.g., hook fasteners, buckle fasteners, keeper loops, etc.), may be made of different materials (e.g., flexible materials, semi-flexible materials, stretchable materials, etc.) and of different dimensions and shapes (e.g., circular loops, elliptical loops, etc.), and may be intended to fasten the power supply 118 onto the wearable electronic device strap 104 of the wearable electronic device 100 (Figures 2B-2D).

[0085] The power supply 118 may be any type of power supply known in the art and may be intended to electrically interact (either wired or wirelessly) with a rechargeable battery in the cavity 106 of the wearable electronic device case 102 without interfering with the operation of one or more power-consuming components (e.g., sensors, screens, etc.) located on the wearable electronic device case 102.

[0086] If the interaction between the power supply 118 and the rechargeable battery is wired, the wearable electronic device charging unit 116 may further include a projection, for example, a projection 122 extending from one of its surfaces. The projection 122 allows the power supply 118 to be connected to a wire, for example, a wire 124, which at its distal end is connected to a rechargeable battery housed in the wearable electronic device case 102 in order to transmit current from the wearable electronic device charging unit 116 to the rechargeable battery. The wire 124 may further include a designated plug 126 located at its distal end, which is configured to allow interaction between the wire 124 and at least one electrical connector 108, and to allow transmission of current from the wearable electronic device charging unit 116 to the rechargeable battery in the cavity 106 of the wearable electronic device case 102, and which may be covered with, for example, a flexible material, semi-flexible, and / or insulating material.

[0087] In some examples, as shown in Figure 4, the wire 124 may extend concealed from the wearable electronic device charging unit 116 to the rechargeable battery in the cavity 106 of the wearable electronic device case 102, without requiring a protrusion 122. In such cases, the wire 124 extends invisibly between the wearable electronic device charging unit 116 and the rechargeable battery in the cavity 106 of the wearable electronic device case 102, along the bottom surface of the wearable electronic device strap 104 (including a passage through the fixing element 120).

[0088] If the interaction between the power supply 118 and the rechargeable battery is performed wirelessly, for example by electromagnetic induction, the wearable electronic device case 102 can be connected to a wireless charger adapter 117 (shown in Figures 5A and 5B). The wireless charger adapter 117 can be attached to a different surface of the wearable electronic device case 102 (e.g., the bottom surface 110) using any mounting means known in the art (e.g., mechanical fixtures, magnets, fasteners, snaps, reusable adhesives, vacuum suction means, etc.) and may include (i) an antenna, (ii) a number of passive conductive components, and (iii) an induction coil (all not shown), the induction coil being used to form an electrical induction, by which the power supply 118 charges the rechargeable battery in the wearable electronic device case 102.

[0089] The wireless charger adapter 117 can electrically interact with the power supply 118, for example, via one or more conductors (not shown), with one end connected to the power supply 118 and the other end connected to the induction coil of the wireless charger adapter 117. For example, when current flows from the power supply 118 through one or more conductors to the induction coil of the wireless charger adapter 117, a magnetic field is generated near the induction coil. The generated magnetic field causes voltage induction within the induction coil, which inductively transfers power from the wireless charger adapter 117 to the rechargeable battery in the wearable electronic device case 102.

[0090] In some examples, one or more conductors include two or more conductors intended to form a closed electrical circuit between the power supply 118 and the rechargeable battery in the cavity 106 of the wearable electronic device case 102. By not using a single conductor to form the aforementioned closed electrical circuit, the volume and thickness of each of the two or more conductors can be made much thinner (allowing for a more comfortable fit of the wearable electronic device 100).

[0091] In some examples, the wireless charger adapter 117 may include a thermocouple placed near the induction coil of the wireless charger adapter 117. The thermocouple is intended to provide real-time temperature measurement of the surface of the wireless charger adapter 117 and to serve as a precaution against overheating damage that may occur if the induction coil of the wireless charger adapter 117 overheats during its operation.

[0092] In some examples, as shown in Figure 5A, the wireless charger adapter 117 includes one or more openings, for example, openings 119a to 119c positioned corresponding to the locations of sensors 112a to 112c, and the openings are intended to allow sensors 112a to 112c to operate without obstruction during charging. In other examples, as shown in Figure 5B, the wireless charger adapter 117 may include transparent areas 121 corresponding to the locations of sensors 112a to 112c, so that sensors 112a to 112 can operate periodically during charging without being blocked by the wireless charger adapter 117.

[0093] It should be noted that the relatively small number of parts in the wireless charger adapter 117 allows for minimizing the volume and thickness of the wireless charger adapter 117, which is intended to enable comfortable wear and a more natural appearance for the watch.

[0094] It should be noted that, by different mounting methods, the wireless charger adapter 117 can be attached to any wearable electronic device known in the art.

[0095] In some examples, the induction coil of the wireless charger adapter 117 can be attached to the bottom surface of the wearable electronic device case 102 using fastening elements, such as magnets or designated mechanical fixtures (made of plastic or other insulating material), the fastening elements wrap around the bottom surface of the wearable electronic device case 102 (for example, by snapping them onto the bottom surface of the wearable electronic device case 102), and hold the induction coil between the surface of the wearable electronic device case 102 and the designated mechanical fixture. In this way, a more reliable and mechanically secure connection is formed. Note that when a designated mechanical fixture is used, a multilayer structure is formed consisting of a first layer (the bottom surface of the wearable electronic device case 102), a second layer (the induction coil), and a third layer (the fastening elements). Note also that the induction coil can be wrapped in an additional fretic layer designed to direct the magnetic field generated in a specific direction.

[0096] In some examples, the power supply 118 may include an indicator that shows the status of the power supply 118 or the rechargeable battery (e.g., remaining power) (when the power supply 118 electrically interacts with the rechargeable battery). The indicator may include at least one light source, for example, a light-emitting diode (LED) that provides a visual representation of the power status of the power supply 118 or the rechargeable battery.

[0097] In some examples, the power supply 118 is placed in a designated housing made of, for example, a rigid or semi-rigid material, which is intended to protect the power supply 118 from external hazards such as weather conditions or flooding.

[0098] In some examples, referring to both types of electrical interaction between the power supply 118 and the rechargeable battery in the cavity 106 of the wearable electronic device case 102 described above, the electrical interaction is controlled, for example, by a designated button located on either the power supply 118 or the wearable electronic device case 102. The designated button may allow the user of the wearable electronic device 100 to initiate the charging operation of the rechargeable battery upon request.

[0099] Now, let's focus on the electronic device charging unit 116.

[0100] Figure 6 is a schematic block diagram showing one example of a wearable electronic device charging unit 116 according to the subject matter of this disclosure.

[0101] According to the subject matter of this disclosure, the wearable electronic device charging unit 116 may be equipped with a network interface 206. The network interface 206 (e.g., a network card, Wi-Fi client, Li-Fi client, 3G / 4G client, or any other component) enables the wearable electronic device charging unit 116 to communicate with an external system via a network and to handle inbound and outbound communications from such a system. For example, the wearable electronic device charging unit 116 can receive information regarding the power level of a rechargeable battery in the wearable electronic device case 102 via the network interface 206.

[0102] The wearable electronic device charging unit 116 may further include, or be associated with, a data repository 204 (for example, a database, a storage system, a memory containing read-only memory (ROM), random access memory (RAM), or any other type of memory) configured to store data optionally including charging patterns, number of charges, charging period, and pre-scheduled charging periods. The data repository 204 may be further configured to allow retrieval, and / or updating, and / or deletion of the stored data.

[0103] It should be noted that in some examples, the data repository 204 may be distributed, for example, via a wired or wireless network to which the wearable electronic device charging unit 116 can connect (using the network interface 206), while the wearable electronic device charging unit 116 is accessing the information stored in the data repository 204.

[0104] The wearable electronic device charging unit 116 further comprises a processing circuit 202. The processing circuit 202 may be one or more processing units (e.g., a central processing unit), a microprocessor, a microcontroller (e.g., a microcontroller unit (MCU)), or any other computing device or module including multiple and / or parallel and / or distributed processing units, which are adapted to process data independently or collaboratively in order to control the resources of the associated wearable electronic device charging unit 116 and to enable operations related to the resources of the wearable electronic device charging unit 116.

[0105] The processing circuit 202 includes a charging module 0 configured to perform a charging process, as will be further described herein with reference to Figure 7 in particular.

[0106] Looking at Figure 7, a flowchart is shown illustrating an example of a series of operations performed for charging a wearable electronic device, as described in the subject of this disclosure.

[0107] Therefore, the wearable electronic device charging unit 116 can be configured to perform the charging process 300 using, for example, a charging module 208.

[0108] For this purpose, during the electrical interaction between the wearable electronic device charging unit 116 and the rechargeable battery of the wearable electronic device case 102, the wearable electronic device charging unit 116 obtains information about its power level from the rechargeable battery (block 302).

[0109] When information regarding the power level of the rechargeable battery reaches the wearable electronic device charging unit 116, the wearable electronic device charging unit 116 compares this information with a predetermined threshold or threshold range via its charging module 208 (block 304). If the power level of the rechargeable battery falls below the predetermined threshold or threshold range, the wearable electronic device charging unit 116 begins transferring current from the wearable electronic device charging unit 116 to the rechargeable battery of the wearable electronic device 100 (block 306).

[0110] When the power level of the rechargeable battery reaches, for example, its maximum value or a predetermined value, the wearable electronic device charging unit 116 terminates current transmission.

[0111] Therefore, as an example, according to the example described above, during the electrical interaction between the wearable electronic device charging unit 116 and the rechargeable battery of the smartwatch 100, the wearable electronic device charging unit 116 obtains information from the rechargeable battery indicating that the power level of the rechargeable battery is 50%.

[0112] The wearable electronic device charging unit 116 compares the power level of the rechargeable battery (50%) to a predetermined threshold (75%) via its charging module 208. Since the power level of the rechargeable battery is below the predetermined threshold (50% vs. 75%), the wearable electronic device charging unit 116 begins transferring current from the wearable electronic device charging unit 116 to the rechargeable battery.

[0113] Current transfer stops when the power level of the rechargeable battery reaches its maximum value of 100%.

[0114] In another embodiment, the rechargeable battery of the wearable electronic device 100 can be connected to an internal charging circuit located within the wearable electronic device 100, and as a result, when electrical interactions are collected between the wearable electronic device charging unit 116 and the rechargeable battery, the internal charging circuit controls the charging of the rechargeable battery by adjusting the flow of electricity transmitted from the wearable electronic device charging unit 116 to the rechargeable battery (i.e., by switching the flow of electricity from a closed electrical circuit to an open electrical circuit).

[0115] Referring to Figure 7, note that some blocks can be integrated into a single integrated block, or they can be broken down into several blocks, and / or other blocks can be added.
