[0002] Wearable devices can integrate technology with traditional devices to perform functions that traditional wearable devices lack, such as collecting health data. Currently, many aspects of life require counting. However, counting by the human brain is prone to errors or forgetting. Using smart devices like smartphones or pen and paper for counting is relatively inconvenient and unsuitable for situations requiring rapid counting. Existing wearable devices lack counting functionality, making counting tasks extremely cumbersome. Utility Model Content
[0003] Therefore, it is necessary to provide a countable wearable device that, through the cooperation of a Hall sensor and a counting magnetic component, enables the wearable device to have a counting function, greatly improving the user experience.
[0004] A countable wearable device includes a housing and a counting assembly. The housing includes an inner shell and an outer shell that are annularly connected and rotatably connected to each other, forming an annular accommodating space between the inner shell and the outer shell. The counting assembly includes a Hall sensor and a counting magnetic element located in the accommodating space. The Hall sensor is provided on one of the inner shell and the outer shell, and the counting magnetic element is provided on the other.

[0005] In the countable wearable device provided in this application, a Hall sensor and a counting magnetic element are used in conjunction to measure the rotational speed of the countable wearable device or count the number of times an object moves, utilizing the Hall effect. When the inner shell is equipped with a Hall sensor and the outer shell is equipped with a counting magnetic element, both the Hall sensor and the counting magnetic element are located within the accommodating space. Rotating the outer shell changes the relative position between the outer and inner shells, and consequently changes the relative positional relationship between the counting magnetic element and the Hall sensor. This generates an electromotive force in a direction perpendicular to the magnetic field. By measuring this electromotive force, the number of times the outer shell rotates can be sensed, thereby realizing the counting function of the countable wearable device.
[0006] In one embodiment, a limiting magnetic element is further included. The limiting magnetic element and the Hall sensor are disposed on the same inner or outer shell.

[0012] In one embodiment, the device includes a circuit board, a battery, and a charging port. The Hall sensor, the circuit board, the battery, and the charging port are disposed on the same inner or outer shell, and the Hall sensor, the battery, and the charging port are electrically connected to the circuit board.

[0028] In current technology, many aspects of life require counting. However, counting by the human brain is prone to errors or forgetting. Using smart devices, such as mobile phones, or pen and paper for counting is cumbersome and inconvenient, unsuitable for situations requiring rapid counting. Existing wearable devices lack counting functionality, further complicating counting tasks. Meanwhile, wearable devices with counting capabilities could cater to Muslims, allowing them to count prayers. Traditionally, Muslims use rosaries (33 beads per string) for counting. A counting wearable device with health monitoring capabilities, a rotating outer ring, and counting functionality would provide a user experience closer to traditional rosaries, significantly improving the overall experience.
[0029] refer to Figures 1 to 7 To address the aforementioned problems, this application provides a countable wearable device 10, including a housing 20 and a counting component 30. The housing 20 includes an inner shell 21 and an outer shell 22 that are annular and rotatably connected to each other, forming an annular accommodating space 40 between the inner shell 21 and the outer shell 22. The counting component 30 includes a Hall sensor 31 and a counting magnetic element 32 located in the accommodating space 40. One of the inner shell 21 and the outer shell 22 is provided with the Hall sensor 31, and the other is provided with the counting magnetic element 32. The Hall sensor 31 and the counting magnetic element 32 are located in the accommodating space 40. The following embodiment uses a ring as an example of a countable wearable device.
[0030] See Figures 2-7The countable wearable device 10 includes a housing 20 and a counting component 30. The housing 20 forms the outer structure of a ring, and the counting component 30 enables the counting function of the wearable device 10. The wearable device 10 has a ring-shaped structure. The inner shell 21 and the outer shell 22 are rotatable relative to each other. When the user rotates the outer shell 22, the relative position of the outer shell 22 and the inner shell 21 changes. An annular accommodating space 40 is formed between the inner shell 21 and the outer shell 22, and the counting component 30 of the wearable device 10 can be placed in the accommodating space 40. The counting component 30 is used to realize the counting function of the wearable device 10. The counting component 30 includes a Hall sensor 31 and a counting magnetic element 32. Both the Hall sensor 31 and the counting magnetic element 32 are located in the accommodating space 40. The Hall sensor 31 is a magnetic field sensor based on the Hall effect, which can convert a changing magnetic field into a change in output voltage. The Hall effect refers to the potential difference generated inside a conductor when current passes through it under the influence of a magnetic field. The Hall sensor 31 utilizes this principle to convert changes in the magnetic field into changes in an electrical signal, thereby achieving the measurement of the magnetic field. The Hall sensor 31 works in conjunction with the counting magnetic element 32 to measure the rotational speed of the countable wearable device 10 or count the number of times an object moves, through the Hall effect. The countable wearable device 10 contains a counting magnetic element 32. For example, when this counting magnetic element 32 is placed in a magnetic field with a magnetic induction intensity of B and a current flows through it, an electromotive force is generated in the direction perpendicular to both the current and the magnetic field; this phenomenon is called the Hall effect. By measuring this electromotive force, the rotational speed or the number of times an object moves can be determined. Specifically, in some embodiments, the inner shell 21 is provided with a Hall sensor 31, and the outer shell 22 is provided with a counting magnetic element 32. Both the Hall sensor 31 and the counting magnetic element 32 are located in the accommodating space 40. When the outer shell 22 is rotated, the relative position of the outer shell 22 and the inner shell 21 changes, and the relative positional relationship between the counting magnetic element 32 and the Hall sensor 31 changes. At this time, an electromotive force is generated in the direction perpendicular to the magnetic field. By measuring this electromotive force, the number of rotations of the outer shell 22 can be sensed, thereby realizing the counting function of the countable wearable device 10. In other embodiments, the outer shell 22 is provided with a Hall sensor 31, and the inner shell 21 is provided with a counting magnetic element 32. Both the Hall sensor 31 and the counting magnetic element 32 are located in the accommodating space 40. When the inner shell 21 is rotated, the relative position of the inner shell 21 and the outer shell 22 changes, and the relative positional relationship between the counting magnetic element 32 and the Hall sensor 31 changes. At this time, an electromotive force is generated in the direction perpendicular to the magnetic field. By measuring this electromotive force, the number of rotations of the outer shell 22 can be sensed, thereby realizing the counting function of the wearable device 10.
[0031] See Figures 3-7The countable wearable device 10 also includes a limiting magnetic element 50, which acts on the counting magnetic element 32 to provide a tactile resistance during rotational counting. Specifically, the limiting magnetic element 50 and the Hall sensor 31 are simultaneously disposed on the inner shell 21, or the limiting magnetic element 50 and the Hall sensor 31 are simultaneously disposed on the outer shell 22. The counting magnetic element 32 can rotate with the inner shell 21 or the outer shell 22, thereby switching between a first position and a second position. The switching process of the counting magnetic element 32 generates an electromotive force. By measuring this electromotive force, the number of rotations of the outer shell 22 or the inner shell 21 can be determined, thereby realizing the counting function of the countable wearable device 10. A magnetic force can be generated between the limiting magnetic element 50 and the counting magnetic element 32. This magnetic force can provide resistance when the countable wearable device 10 is rotated to start and a restoring force when the magnets are close to each other, providing a tactile resistance during rotational counting and offering the user an excellent rotational feel. At the same time, counting is achieved through rotation. For Muslims, a countable wearable device 10 is used to count during prayer, making the user experience closer to that of traditional prayer beads and greatly improving the user experience.
[0032] When the counting magnetic element 32 is in the first position, it attracts the limiting magnetic element 50 radially or axially in the housing 20. The attraction force provides the user with a resistance feel during rotation counting, offering excellent rotational feel. In some embodiments, multiple limiting magnetic elements 50 are disposed in the inner housing 21 to provide resistance feel during rotation counting, and the multiple limiting magnetic elements 50 are arranged at equal intervals along the circumference of the inner housing 21. Multiple counting magnetic elements 32, the same number as the limiting magnetic elements 50, are disposed in the outer housing 22. The counting magnetic elements 32 cooperate with the Hall sensor 31 to realize the counting function of the counting component 30. The multiple counting magnetic elements 32 are arranged at equal intervals along the circumference of the outer housing 22. For example, four limiting magnetic elements 50 can be provided, with adjacent two limiting magnetic elements 50 at 90° to the circumference of the inner housing 21. In this case, four counting magnetic elements 32 are provided, and the four limiting magnetic elements 50 and four counting magnetic elements 32 are arranged at equal intervals along the circumference of the ring. When the counting magnetic element 32 passes the Hall sensor 31, the count is incremented by one. When the counting magnetic element 32 passes the Hall sensor 31 and then quickly returns to pass the Hall sensor 31, the count is reset to zero. When the counting magnetic element 32 is in the first position, it is opposite to the limiting magnetic element 50 in the radial direction of the housing 20. The counting magnetic element 32 and the limiting magnetic element 50 attract each other, which can provide resistance during rotational start-up and reset force when the magnets come close to each other.
[0033] See Figures 5-7To ensure a tactile feedback when rotating the outer casing 22, the magnetic poles of the limiting magnetic element 50 near the counting magnetic element 32 can be different from those of the counting magnetic element 32 near the limiting magnetic element 50. For example, the magnetic pole of the limiting magnetic element 50 near the counting magnetic element 32 can be set as the N pole, and the magnetic pole of the counting magnetic element 32 near the limiting magnetic element 50 can be set as the S pole. When the N and S poles are opposite each other, they can provide resistance during rotation and a restoring force to bring the magnets closer together. When four limiting magnetic elements 50 and four counting magnetic elements 32 are provided, the four sets of magnetic elements form four levels of rotation, and each rotation can be set to 90°.
[0034] See Figures 3-7 The outer shell 22 and the inner shell 21 are rotatably connected by a ball bearing assembly 60. The ball bearing assembly 60 is disposed within the accommodating space 40 of the countable wearable device 10. The ball bearing assembly 60 is rotatable. Specifically, the ball bearing assembly 60 includes a support frame 61 and a plurality of balls 62. The support frame 61 is annular and has a plurality of mounting rings 611. The balls 62 are confined within the mounting rings 611, and each ball 62 corresponds one-to-one with a mounting ring 611. All balls 62 are confined within their corresponding mounting rings 611. The outer shell 22 has a first ball bearing assembly 62 on the side near the balls 62. The inner shell 21 has a second groove 211 on the side near the ball 62. The first groove 221 and the second groove 211 can both be set as semi-circular grooves. The opposite sides of the ball 62 can respectively abut in the first groove 221 and the second groove 211 to limit the ball 62 in the countable wearable device 10. At the same time, the limiting of the ball 62 by the first groove 221 and the second groove 211 will not affect the sliding of the ball 62. That is, the ball 62 can slide along the first groove 221 and the second groove 211 to realize the rotation of the ball 62.
[0035] The limiting magnetic component 50, the counting magnetic component 32, and the ball bearing 62 are spaced apart to prevent interference during rotation. The limiting magnetic component 50 has a groove 51 on the side near the ball bearing 62 for the ball bearing 62 to pass through, and the counting magnetic component 32 has a groove 321 on the side near the ball bearing 62 for the ball bearing 62 to pass through. The limiting magnetic component 50 is located in one of the first groove 221 and the second groove 211, and the counting magnetic component 32 is located in the other of the first groove 221 and the second groove 211. For example, if the limiting magnetic component 50 is near the inner shell 21 and the counting magnetic component 32 is near the outer shell 22, and the limiting magnetic component 50 is located in the second groove 211 and the counting magnetic component 32 is located in the first groove 221, the internal structure of the countable wearable device 10 can be made compact, simplifying assembly.
[0036] The countable wearable device 10 includes a circuit board 71, a battery 72, and a charging port 73. The circuit board 71 and battery 72 can be placed within the housing space 40 of the countable wearable device 10. In some embodiments, the Hall sensor 31, circuit board 71, battery 72, and charging port 73 are disposed in the same inner shell 21, and the Hall sensor 31, battery 72, and charging port 73 are electrically connected to the circuit board 71 to ensure the function of the counting component 30. In some embodiments, the countable wearable device 10 also includes a piezoelectric oscillator 81 and a sensing component. The piezoelectric oscillator 81 is disposed in the inner shell 21 and electrically connected to the circuit board 71, and the piezoelectric oscillator 81 can provide vibration feedback. The piezoelectric oscillator 81 can be a piezoelectric ceramic oscillator, which operates using the piezoelectric effect. When an electric field is applied to the piezoelectric ceramic, the ceramic deforms; conversely, when mechanical stress is applied to the piezoelectric ceramic, a potential difference is generated. This periodic conversion of electrical and mechanical energy allows the piezoelectric ceramic oscillator to generate a stable oscillation frequency in the circuit. The sensing component can be used for health detection. The inner shell 21 has a mounting hole 212 on the side away from the outer shell 22. The sensing component is located in the mounting hole 212 and is electrically connected to the circuit board 71. The sensing component is close to the finger to realize the health detection function of the sensing component. This makes the countable wearable device 10 provided by this application have the function of health detection, enriches the functionality of the countable wearable device 10, and can greatly improve the user experience.
[0037] The countable wearable device 10 also includes two dust covers 90, which are respectively located on opposite sides of the housing 20 in the axial direction. The dust covers 90 are located at the ends of the ring and can prevent dust from entering the ring, keeping the accommodating space 40 inside the ring in a closed state. This helps protect the circuit board 71, the counting component 30, and the sensing component inside the ring. Each dust cover 90 abuts against the outer shell 22 and the inner shell 21 at opposite ends in the radial direction of the housing 20 to seal the accommodating space 40. During installation, the ball bearing 62 can be installed in the mounting ring 611 first and fixed with the support bracket 61. After installing the ball bearing 62 and the support bracket 61, the circuit board 71, the Hall sensor 31, and the sensing component are installed. Finally, the dust covers 90 on the left and right sides are installed. The assembly is simple and easy to operate.
[0038] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
