Description
Technical Field
[0001] This application relates to the field of fitness trackers, and in particular to an energy-saving fitness tracker. Background Technology
[0002] A fitness tracker is a type of smart bracelet that typically consists of a first strap, a second strap, and a smart watch face. The smart watch face can monitor a person's heart rate during exercise and can also measure stress through heart rate variability. However, both of these monitoring functions are relatively power-consuming. In order to reduce power consumption and achieve energy conservation and environmental protection, some people add a power generation module to the fitness tracker to enable it to generate its own power and power the tracker, thereby achieving energy-saving effects.
[0003] However, existing energy-saving fitness trackers have some drawbacks: by adding a micro solar panel to the smart dial to generate electricity by absorbing light energy when the human body is moving, the micro solar panel is only exposed to light for a short time because the tracker is constantly shaking during exercise, resulting in low power generation efficiency; and in cloudy or rainy weather, the light is greatly weakened, and the micro solar panel basically does not generate electricity, making it difficult for existing energy-saving fitness trackers to achieve energy-saving effects.
[0004] There is currently no effective solution to the problem that existing energy-saving fitness trackers have difficulty absorbing light energy when shaken, leading to unstable power generation. Utility Model Content
[0005] This invention provides an energy-saving fitness tracker to solve the problem that existing energy-saving fitness trackers have difficulty absorbing light energy when shaken, leading to unstable power generation.
[0006] This utility model provides an energy-saving sports bracelet, which includes a dial, a first strap, a second strap, and an energy-saving component. The first strap is installed on the first side of the dial. The energy-saving component includes a hollow box, two conductive plates, a non-metallic friction block, and several springs. The first side of the hollow box is rotatably installed on the second side of the dial, and the second strap is installed on the second side of the hollow box. The two conductive plates are symmetrically installed on the inner wall of the hollow box. Several springs connect the side of the non-metallic friction block to the inner wall of the hollow box. The non-metallic friction block is located between the gaps of the two conductive plates. The cross-sections of the two conductive plates are concave, and the cross-section of the non-metallic friction block is elliptical.
[0007] Furthermore, a connecting component is provided on the second side of the dial. The connecting component includes an elastic flange and a locking rod. The elastic flange is fixed on the second side of the dial, and a locking groove is opened at the end of the elastic flange. The locking rod is fixed on the first side of the hollow box.
[0008] Furthermore, a first electrical contact is provided in the card slot, which is electrically connected to the dial, and a second electrical contact is provided on the card lever, with the first and second electrical contacts making sliding contact.
[0009] Furthermore, the dial is electrically connected to the hollow box via wires.
[0010] Furthermore, the first and second watch straps are equipped with a fastening assembly, which includes a frame, a knob, and a toothed roller. The frame is fixed to the end of the first watch strap, and the toothed roller is rotatably mounted on the upper inner side of the frame. One side of the toothed roller's shaft end passes through the frame and is fixed with the knob. The second watch strap has several grooves arranged in sequence, and the toothed roller is used to lock the grooves. A self-locking assembly is provided on the frame for the knob to self-lock.
[0011] Furthermore, the self-locking assembly includes a locking rod, a torsion spring, a gear, and a stop plate. The locking rod is rotatably mounted on the outside of the frame. The torsion spring is sleeved on the shaft of the locking rod, and both ends of the torsion spring are fixed to the shaft of the locking rod and the outside of the frame, respectively. The stop plate is fixed on the outside of the frame and located above the locking rod. The gear is fixed on one side of the knob and coaxially fixed. The outer end of the locking rod is used to mesh with the gear.
[0012] Furthermore, both the first and second watch straps are made of silicone.
[0013] Furthermore, the conductive plate is made of carbon fiber nylon.
[0014] Furthermore, the non-metallic friction block is a polytetrafluoroethylene block.
[0015] Furthermore, the spring is coated with a corrosion-resistant coating.
[0016] Compared with related technologies, the present invention has the following beneficial effects:
[0017] 1. Under the influence of gravity and inertia, the non-metallic friction block undergoes displacement. Under the action of the spring, a portion of the kinetic energy of the non-metallic friction block is converted into the elastic potential energy of the spring each time the direction changes. This ensures that the non-metallic friction block maintains a stable motion state during arm movement, generating electricity through friction with the two conductive plates. Furthermore, because the non-metallic friction block is located between the two conductive plates, even when the arm is moving at multiple angles, the three components can still make contact at the edges during the movement. The non-metallic friction block and the two conductive plates can still generate effective friction and electricity. Compared with existing solar power generation technologies, this application provides more stable power generation, unaffected by weather or arm movements during exercise. This more stable and continuous power generation solves the problem of unstable power generation caused by the difficulty in absorbing light energy during movement in existing energy-saving fitness trackers.
[0018] 2. When fixing the dial and the hollow box, the elastic flange has elasticity and memory. When the lever is inserted into the elastic flange, the elastic flange will undergo an expansion and recovery process, thereby limiting the lever in the slot. The installation is simple and the disassembly is convenient.
[0019] 3. The knob drives the toothed roller to rotate, and the toothed roller drags the groove by friction, which drives the second strap to enter from the bottom of the frame, thereby realizing the tightening operation. More importantly, the toothed roller and several grooves arranged in sequence can be fixed at any position according to the rotation angle, which is equivalent to stepless adjustment. Compared with the existing perforated wristbands, the adjustment range is larger and more sensitive.
[0020] 4. After the gear is worn, it stops rotating. Under the action of the torsion spring, the locking rod resets and re-engages with the gear, thus achieving self-locking.

[0032] An energy-saving fitness tracker is provided in an embodiment of this utility model; please refer to [link / reference]. Figure 1 It includes a dial 1, a first watch strap 2, a second watch strap 21, and an energy-saving component 3.
[0033] The first watch strap 2 is mounted on the first side of the dial 1. The hollow box 31 is rotatably mounted on the second side of the dial 1 from the first side, and the second watch strap 21 is mounted on the second side of the hollow box 31. This connection sequence takes into account the bone structure of the human wrist. Since there are protruding bones at the wrist where the first watch strap 2 is worn, the rotatable mounting of the hollow box 31 on the second side of the dial 1 avoids contact between the hollow box 31 and the protruding bones of the wrist, improving wearing comfort. (See also...) Figure 2 and Figure 3 The energy-saving component 3 includes a hollow box 31, two conductive plates 32, a non-metallic friction block 33, and several springs 34. The two conductive plates 32 are symmetrically installed on the inner wall of the hollow box 31. Several springs 34 are connected between the side of the non-metallic friction block 33 and the inner wall of the hollow box 31, as shown in the figure. Springs 34 are fixed on all four sides of the non-metallic friction block 33, thereby enabling rebound at multiple angles. The non-metallic friction block 33 is located between the gaps of the two conductive plates 32. The cross-sections of the two conductive plates 32 are concave, and the cross-section of the non-metallic friction block 33 is elliptical. The two conductive plates 32, the non-metallic friction block 33, and the hollow box 31 are electrically connected to the dial 1. During movement, as the dial 1 swings with the arm, the hollow box 31 also moves in the first direction. Under the influence of gravity and inertia, the non-metallic friction block 33 remains briefly stationary relative to its own position in space, but moves in the opposite direction relative to the hollow box 31. Subsequently, with the arm's movement, the hollow box 31 also moves in the second direction. Under the influence of gravity and inertia, the non-metallic friction block 33 moves in the opposite direction. Under the action of the spring 34, each time the direction changes, a portion of the kinetic energy of the non-metallic friction block 33 is converted into the elastic potential energy of the spring 34, thus keeping the non-metallic friction block 33 stationary during the arm's movement. A stable motion state generates electricity through friction with the two conductive plates 32, thus enabling the energy-saving component 3 to maintain stable power generation and supply power to the fitness tracker during movement, achieving an energy-saving effect. At the same time, since the non-metallic friction block 33 is located between the two conductive plates 32, even when the arm is in multi-angle movement, the three can still make contact at the edges during the shaking process. The non-metallic friction block 33 and the two conductive plates 32 can still generate effective friction and electricity. Compared with the existing technology of solar power generation, the power generation of this application is more stable, unaffected by weather, and unaffected by the arm movement during exercise. The power generation is more stable and continuous, solving the problem that the existing energy-saving fitness trackers have difficulty absorbing light energy during shaking, resulting in unstable power generation.
[0034] In this embodiment, the first strap 2 and the second strap 21 are silicone straps, which are more comfortable and less likely to cause allergies compared to other materials; the conductive plate 32 is a carbon fiber nylon plate; and the non-metallic friction block 33 is a friction block made of polytetrafluoroethylene (PTFE). These two materials are the basic materials for triboelectric nanogenerators and have been proven to be used for micro-power generation, as detailed in (Triboelectric Nanogenerator TENG).
[0035] Combination Figure 1 , Figure 4 and Figure 5 A connecting component 4 is provided on the second side of the dial 1. The connecting component 4 includes an elastic flange 41 and a locking rod 42. The elastic flange 41 is fixed to the second side of the dial 1, and a locking groove 411 is opened at the end of the elastic flange 41. The locking rod 42 is fixed to the first side of the hollow box 31. The elastic flange 41 has elasticity and memory. When the locking rod 42 is locked in the elastic flange 41, the elastic flange 41 will undergo an expansion and recovery process, thereby limiting the locking rod 42 in the locking groove 411. The installation is simple and the disassembly is convenient.
[0036] To reduce structural complexity and improve portability, a first electrical contact can be provided in the slot 411, which is electrically connected to the dial 1. A second electrical contact is provided on the lever 42, and the first and second electrical contacts slide in contact. Alternatively, the dial 1 can be electrically connected to the hollow box 31 via a wire.
[0037] Combination Figure 1 , Figure 6 and Figure 7 The first strap 2 and the second strap 21 are equipped with a fastening assembly 5, which includes a frame 51, a knob 52, and a toothed roller 53. The frame 51 is fixed to the end of the first strap 2, and the toothed roller 53 is rotatably mounted on the upper inner side of the frame 51. One side shaft end of the toothed roller 53 passes through the frame 51 and is fixed with the knob 52. The second strap 21 has several grooves 54 arranged in sequence, and the toothed roller 53 is used to lock the grooves 54. When in use, the knob 52 is turned, which drives the toothed roller 53 to rotate. The toothed roller 53 rubs and drags the grooves 54, causing the second strap 21 to enter from the bottom of the frame 51, thereby achieving the tightening operation. More importantly, the toothed roller 53 and the several grooves 54 arranged in sequence can be fixed at any position according to the rotation angle, which is equivalent to stepless adjustment. Compared with the existing perforated wristbands, the adjustment range is larger and more sensitive.
[0038] To improve the stability of the wristband, a self-locking component 6 is provided on the frame 51 for locking the knob 52. The self-locking component 6 includes a locking rod 61, a torsion spring 62, a gear 63, and a stop plate 64. The locking rod 61 is rotatably mounted on the outside of the frame 51. The torsion spring 62 is sleeved on the shaft of the locking rod 61, and both ends of the torsion spring 62 are fixed to the shaft of the locking rod 61 and the outside of the frame 51, respectively. The stop plate 64 is fixed on the outside of the frame 51 and located above the locking rod 61. The gear 63 is fixed on one side of the knob 52 and coaxially fixed. The outer end of the locking rod 61 is used to mesh with the gear 63. During use, follow... Figure 6 When the gear 63 is rotated counterclockwise, the locking rod 61 will be subjected to force and rotate clockwise, thus allowing for smooth wearing. After wearing, the gear 63 stops rotating, and the locking rod 61 resets and re-engages with the gear 63 under the action of the torsion spring 62, thereby achieving self-locking. The structure is simple, and the baffle 64 can prevent fooling and prevent the gear 63 from rotating in the opposite direction.
[0039] Spring 34 is prone to rust, so in order to extend its service life, spring 34 is coated with a corrosion-resistant coating.
[0040] In summary, this utility model, by maintaining a stable motion state during arm movement, allows the non-metallic friction block 33 to generate electricity through friction with the two conductive plates 32, thereby ensuring stable power generation of the energy-saving component 3 during movement and supplying power to the fitness tracker, achieving an energy-saving effect. Simultaneously, because the non-metallic friction block 33 is located between the two conductive plates 32, even when the arm is in multi-angle movement, the three components can still make contact at the edges during movement, and the non-metallic friction block 33 and the two conductive plates 32 can still generate effective friction and electricity. Compared with existing photovoltaic power generation technologies, the power generation of this application is more stable, unaffected by weather, and unaffected by arm movements during exercise; the fixed dial 1 and hollow box 31... When the elastic flange 41 is engaged, it has elasticity and memory. When the locking lever 42 is engaged in the elastic flange 41, the elastic flange 41 will undergo an expansion and recovery process, thereby limiting the locking lever 42 in the locking groove 411. The installation is simple and the disassembly is convenient. The knob 52 drives the toothed roller 53 to rotate. The toothed roller 53 rubs and drags the groove 54, driving the second strap 21 to enter from the bottom of the frame 51, thereby realizing the tightening operation. More importantly, the toothed roller 53 and several grooves 54 arranged in sequence can be fixed at any position according to the rotation angle, which is equivalent to stepless adjustment. Compared with the existing perforated bracelet, the adjustment range is larger and more sensitive. After the wear is finished, the gear 63 stops rotating. Under the action of the torsion spring 62, the locking lever 61 resets and re-meshes with the gear 63, thereby realizing self-locking.
