Description

Technical Field

[0001] The present application relates to the wearable field, and in particular to a smart wearable device and a power supply device for the smart wearable device. Background Art

[0002] Smart wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories.

[0003] Smart wearables are multitasking devices that can be used without interrupting the user's movements and can be augmented into the user's existing movements. Therefore, the integration of a smart wearable device and the user is similar to a prosthesis, becoming an extension of the user's brain or body.

[0004] One of the main features of wearable devices is sustainability, that is, the ability to maintain stable interaction between the computer and the user, which poses a challenge to the power supply of wearable devices.

[0005] In the prior art, smart wearable devices are often worn on the user's body using a strap-like structure. For example, smart headsets typically use a head strap, while smart watches use a wrist strap. Furthermore, to ensure stable power supply, prior art smart wearable devices often integrate the power supply and power consumption into a single main unit. This can easily lead to the center of gravity of the smart wearable device being concentrated on one side of the main unit, reducing wearing comfort. Furthermore, the high load-bearing capacity requirements of the strap also indirectly increase the overall weight of the strap and, consequently, the smart wearable device. Summary of the Invention

[0006] In order to solve the above problems or at least partially solve the above technical problems, in one embodiment of the present application, a smart wearable device is provided, including:

[0007] An electrical device worn on one side of the user's body;

[0010] A power supply conductor, one end of which is connected to the power-consuming device, and the other end of which is electrically connected to the battery through the storage mechanism, and the battery supplies power to the power-consuming device through the power supply conductor;

[0011] The storage mechanism can absorb and release the power conductive strip to adjust the length of the portion of the power conductive strip located outside the power supply device.

[0012] Accordingly, an embodiment of the present application further provides a power supply device for a smart wearable device, comprising:

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] Implementation Method 1

[0028] The inventors of the present application discovered that when the power-consuming device and the power-supply device are separately provided, since they need to be connected by a power cord, the adjustment of the power cord becomes a technical problem to be solved.

[0029] In view of this, the first embodiment of the present application provides a smart wearable device, see Figure 1 As shown, in this application, a head-mounted device is used as an example for explanation, including:

[0030] The electrical device 1 is worn on one side of the user's body. In head-mounted devices, the electrical device 1 can be a head-mounted display (HMD). The head-mounted display sends optical signals to the eyes and sound signals to the ears through various optical devices and acoustic devices, which can achieve different effects such as virtual reality (VR), augmented reality (AR), and mixed reality (MR). It is worth mentioning that when the smart wearable device is a head-mounted device, the body part referred to can be the head. When the smart wearable device is a wristband, the body part referred to can be the wrist. Other types of smart wearable devices can also be deduced by analogy.

[0031] Power supply device 2, worn on the other side of the user's body, see Figure 2 As shown, a battery 22 is provided in the power supply device 2. To reduce weight, a lithium battery can usually be used in a head-mounted device. This power supply device 2 is usually wrapped by a housing 21 to protect the internal structure.

[0032] The storage mechanism 3 is provided in the power supply device 2 .

[0033] The power supply conductor 4 has one end connected to the power-consuming device 1 and the other end electrically connected to the battery 22 via the storage mechanism 3. The battery 22 supplies power to the power-consuming device 1 via the power supply conductor 4. The power supply conductor 4 may include only wires for conducting the power supply, or it may also include wires that enhance the connection, such as a fixing strap.

[0034] See also Figures 1 to 5 As shown, optionally, a strap connection ring 23 is provided on the power supply device 2. The smart wearable device also includes:

[0035] The connecting belt 5 has a fixed end connected to the power-consuming device 1, and an adjustable end passing through the strap connection ring 23 and connected to the middle of the connecting belt 5. The connecting belt 5 can adjust the distance between the power supply device 2 and the power-consuming device 1 by changing the connection position of the adjustable end and the middle of the connecting belt 5.

[0036] At least a portion of the power conducting strip 4 and the connecting strip 5 are fixed to each other.

[0037] Alternatively, see Figure 5 As shown, a power outlet hole 21a is provided on the power supply device 2, that is, on the housing 21, and the power supply device 2 is connected to the power supply device 2 through the power outlet hole 21a;

[0038] The power outlet hole 21a and the power conducting strip 4 are arranged side by side.

[0039] Taking the head-mounted device of the present application as an example, the connecting strap 5 can be a head strap, which allows the power-consuming device 1 and the power supply device 2 to be comfortably fixed to the user's head. The connecting strap 5 is provided with an outer layer structure that wraps around the connecting strap 5 itself, and the power conductor 4 is fixed within the connecting strap 5 by this outer layer structure. The double-layer structure of the connecting strap 5 and the power conductor 4 ensures connection strength while also improving comfort.

[0040] The storage mechanism 3 of the present application can absorb and release the power conductive strip 4 to adjust the length of the portion of the power conductive strip 4 located outside the power supply device 2 .

[0041] The storage mechanism 3 of this embodiment can be configured to have various structures capable of retracting the power supply conductor 4. For example, a winding mechanism can be used to spirally reel the power supply conductor 4 into the storage mechanism 3, and a torsion spring can be used to maintain the contraction tendency of the power supply conductor 4.

[0042] As a further preferred embodiment of the present application, the present application discloses a storage mechanism 3 with simple structure, convenient operation, low cost and long service life. Figures 3 to 5 As shown, the storage mechanism 3 includes:

[0043] A receiving groove 31 and a cylindrical object 32 disposed in the receiving groove 31 , with the power conducting belt 4 wound around the cylindrical object 32 ;

[0044] The cylinder 32 reciprocates in the receiving groove 31 to adjust the length of the portion of the power conductive belt 4 located outside the power supply device 2 .

[0045] Optionally, the bottom of the receiving groove 31 protrudes toward the direction of the cylindrical object 32 , so that the bottom of the receiving groove 31 has an arc-shaped profile in a cross section along the moving direction of the cylindrical object 32 .

[0046] The arc-shaped receiving groove 31 allows the movement trajectory of the power conducting belt 4 to better fit the curve of the human body, preventing the power conducting belt 4 from being excessively bent at the power outlet hole 21 a, thereby extending the service life.

[0047] Optionally, a positioning member 32a is provided on the cylindrical object 32;

[0048] The storage mechanism 3 further includes:

[0049] One end of the elastic member 33 is connected to the positioning member 32 a , and the other end is fixed relative to the receiving groove 31 . The elastic member 33 is used to reset the position of the cylindrical object 32 .

[0050] The positioning member 32a referred to in the present application may be a shaft extending from the end of the cylindrical object 32, and the elastic member 33 may be a spring or a tension spring.

[0051] With the help of the elastic member 33, the position of the cylinder 32 can be reset, so that the cylinder 32 tends to store the power conductor 4 into the storage mechanism 3, thereby improving the convenience of operation.

[0052] Further optionally, a long hole 31a is opened on the side wall of the receiving groove 31 along the movement direction of the cylindrical object 32;

[0053] The positioning member 32 a is a positioning shaft, which passes through the elongated hole 31 a and is connected to the elastic member 33 located outside the receiving groove 31 .

[0054] The provided elongated hole 31 a can better constrain the movement trajectory of the cylindrical object 32 .

[0055] It is worth mentioning that the cylindrical object 32, elastic member 33, positioning member 32a, elongated hole 31a, etc. of the present application can all be arranged to be bilaterally symmetrical with the central axis of the storage groove 31 as the axis of symmetry to improve the stability of the storage movement.

[0056] Optionally, a connection platform 6 is provided on one side of the storage slot 31 close to the electrical device 1 , and the power conducting belt 4 is connected to the connection platform 6 after passing through the cylindrical object 32 .

[0057] Optionally, based on the above-mentioned connecting platform 6, the storage mechanism 3 further includes:

[0058] The housing 21 is formed with a receiving groove 31, and the fixed end of the elastic member 33 is connected to the housing 21;

[0059] Connecting contact piece (not shown in the figure), provided on the housing 21;

[0060] The housing 21 is further formed with a battery compartment, in which the battery 22 is placed. The connecting contacts are used to connect the electrodes of the connecting platform 6 and the battery 22 .

[0061] By connecting the battery 22 with the unified connection platform 6 , the connection of the power connection strip 5 can be made more stable and the reliability can be improved.

[0062] Based on the above structure, the present application provides a storage process of the power conductive strip 4 as follows:

[0063] 1. When the wearable device is needed, the power-consuming device 1 and the power supply device 2 are respectively located on both sides of the user's body. When the user extends the connecting belt 5, the connecting belt 5 drives the power supply connecting belt 4, and the power supply connecting belt 4 is pulled out of the storage mechanism 3;

[0064] 2. At this point, the power conductor 4 drags the cylindrical member 32, causing it to move along the receiving slot 31 toward the power outlet 21a, until the desired range of motion is achieved. During this movement, the positioning member 32a stretches or compresses the elastic member 33 along the elongated hole 31a, causing the elastic member 33 to accumulate elastic potential energy.

[0065] 3. The user puts on the smart wearable device. To prevent the smart wearable device from falling off and improve comfort, the connecting strap 5 needs to be slightly shortened. At this time, the power conducting strap 4 automatically contracts under the action of the storage mechanism 3.

[0066] 4. Inside the power supply device 2, the elastic member 33 of the storage mechanism 3 releases part of its elastic potential energy, and through the positioning member 32a, the cylindrical object 32 moves a certain distance along the elongated hole 31a in a direction away from the power outlet hole 21a, thereby contracting the power conductor 4.

[0067] 5. When the user needs to take off the smart wearable device, the connecting strap 5 is usually extended again, and then retracted for easy storage. Correspondingly, the storage mechanism 3 can drive the power conductor 4 to move accordingly, so it will not be described in detail.

[0068] Compared to a hoisting mechanism or other storage mechanism 3, the storage mechanism 3 of the present application utilizes the movement of the cylindrical object 32 within the storage slot 31 to drag the power conductor 4 to form the corresponding storage and release movement, resulting in a simpler structure and lower cost. It is particularly worth mentioning that the conductive materials used in the prior art are usually metal materials, which are relatively poor in flexibility. Repeated winding and release processes can easily lead to material fatigue and a relatively short lifespan. However, since the cylindrical object 32 of the present application only moves along the length of the storage slot 31 and does not need to rotate itself, the power conductor 4 does not need to be repeatedly wound up, and thus has a longer service life.

[0069] In summary, the present invention has a simple structure, occupies a small space, and provides both storage for the power conductor 4 and adjustment of the connecting strap 5. By separating the power consumption device 1 and the power supply device 2 of the smart wearable device, the present invention improves wearing comfort. The storage mechanism 3 effectively stores the power conductor 4, preventing compression that could cause bulging. This improves comfort and extends wearer life.

[0070] Implementation Method 2

[0071] A second embodiment of the present application provides a power supply device 2 for a smart wearable device, comprising:

[0072] The housing 21 and the battery 22 are arranged in the housing 21. To reduce weight, lithium batteries are usually used in head-mounted devices.

[0073] The storage mechanism 3 is provided in the housing 21;

[0074] The power supply conductor 4 has one end electrically connected to the battery 22 through the storage mechanism 3 and the other end extending from the housing 21. Figure 1 As shown, the extended power conductive strip 4 can be connected to the electrical device 1 so that the battery 22 can supply power to the electrical device 1 through the power conductive strip 4 .

[0075] The power conducting strip 4 may only include wires for conducting the power supply, or may also include wires for strengthening the connection relationship, such as a fixing strip.

[0076] The storage mechanism can absorb and release the power conductive strip to adjust the length of the portion of the power conductive strip located outside the housing.

[0077] See also Figures 1 to 5 As shown, optionally, a strap connection ring 23 is provided on the power supply device 2 of the smart wearable device. The smart wearable device provided with the power supply device 2 of the smart wearable device may further include:

[0078] The connecting belt 5 has a fixed end connected to the power-consuming device 1, and an adjustable end passing through the strap connection ring 23 and connected to the middle of the connecting belt 5. The connecting belt 5 can adjust the distance between the power supply device 2 and the power-consuming device 1 by changing the connection position of the adjustable end and the middle of the connecting belt 5.

[0079] At least a portion of the power conducting strip 4 and the connecting strip 5 are fixed to each other.

[0080] Alternatively, see Figure 5 As shown, a power outlet hole 21a is provided on the power supply device 2, that is, on the housing 21, and the power supply device 2 is connected to the power supply device 2 through the power outlet hole 21a;

[0081] The power outlet hole 21a and the power conducting strip 4 are arranged side by side.

[0082] Taking the head-mounted device of the present application as an example, the connecting strap 5 can be a head strap, which allows the power-consuming device 1 and the power supply device 2 to be comfortably fixed to the user's head. The connecting strap 5 is provided with an outer layer structure that wraps around the connecting strap 5 itself, and the power conductor 4 is fixed within the connecting strap 5 by this outer layer structure. The double-layer structure of the connecting strap 5 and the power conductor 4 ensures connection strength while also improving comfort.

[0083] The storage mechanism 3 of the present application can absorb and release the power conductive strip 4 to adjust the length of the portion of the power conductive strip 4 located outside the power supply device 2 .

[0084] The storage mechanism 3 of this embodiment can be configured to have various structures capable of retracting the power supply conductor 4. For example, a winding mechanism can be used to spirally reel the power supply conductor 4 into the storage mechanism 3, and a torsion spring can be used to maintain the contraction tendency of the power supply conductor 4.

[0094] With the help of the elastic member 33, the position of the cylinder 32 can be reset, so that the cylinder 32 tends to store the power conductor 4 into the storage mechanism 3, thereby improving the convenience of operation.

[0095] Further optionally, a long hole 31a is opened on the side wall of the receiving groove 31 along the movement direction of the cylindrical object 32;

[0096] The positioning member 32 a is a positioning shaft, which passes through the elongated hole 31 a and is connected to the elastic member 33 located outside the receiving groove 31 .

[0097] The provided elongated hole 31 a can better constrain the movement trajectory of the cylindrical object 32 .

[0098] It is worth mentioning that the cylindrical object 32, elastic member 33, positioning member 32a, elongated hole 31a, etc. of the present application can all be arranged to be bilaterally symmetrical with the central axis of the storage groove 31 as the axis of symmetry to improve the stability of the storage movement.

[0099] Optionally, a connection platform 6 is provided on one side of the storage slot 31 close to the electrical device 1 , and the power conducting belt 4 is connected to the connection platform 6 after passing through the cylindrical object 32 .

[0100] Optionally, based on the above-mentioned connecting platform 6, the storage mechanism 3 further includes:

[0101] The housing 21 is formed with a receiving groove 31, and the fixed end of the elastic member 33 is connected to the housing 21;

[0102] Connecting contact piece (not shown in the figure), provided on the housing 21;

[0103] The housing 21 is further formed with a battery compartment, in which the battery 22 is placed. The connecting contacts are used to connect the electrodes of the connecting platform 6 and the battery 22 .

[0104] By connecting the battery 22 with the unified connection platform 6 , the connection of the power connection strip 5 can be made more stable and the reliability can be improved.

[0105] Based on the above structure, the present application provides a storage process of the power conductive strip 4 as follows:
