Description

Technical Field

[0001] This invention belongs to the field of smart wearable device technology, specifically relating to a wearable research and learning safety home-school information interaction device. Background Technology

[0002] With the increasing popularity of study tours, student safety during outdoor learning activities has become a major concern. Wearable smart devices, as an effective safety monitoring tool, have been gradually applied in study tour scenarios. These devices typically take the form of smartwatches, smart bracelets, or electronic student IDs, integrating positioning, communication, physiological sensors, and alarm modules. They not only enable student location tracking and emergency assistance but also, through data interaction with cloud platforms and parent-child apps, allow for real-time push and sharing of information such as student entry and exit from school, attendance records, and health status, building an information bridge between home and school.

[0003] To improve wearing comfort, a certain gap is usually left between the watch strap and the skin, meaning the device is not completely fixed to the wrist. The physiological monitoring modules (such as heart rate sensors and blood oxygen sensors) of existing wearable devices are typically fixed to the bottom of the device. During study tours, students frequently engage in vigorous activities such as running, climbing, and swinging their arms, causing the device's position to change with these movements. This results in the relative position between the sensor and the skin not remaining stable. When the sensor detaches from the skin or only contacts it with a large gap, the effective acquisition of photoelectric signals will be severely interfered with, leading to interruptions or significant distortion of health monitoring data. Summary of the Invention

[0004] To address the issue of insufficient adhesion between the detection module and the skin due to strenuous exercise, this invention proposes a wearable educational safety home-school information interaction device to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention is a wearable educational safety home-school information interaction device, including a smart watch face. A fixed watch strap is rotatably connected to one side of the smart watch face, and a rotating sleeve is rotatably connected to the other side of the smart watch face. A traction watch strap is slidably connected inside the rotating sleeve. A storage slot is provided at the bottom of the smart watch face, and an elastic connecting component connected to the traction watch strap is provided inside the storage slot. A hollow cylinder is slidably connected inside the storage slot. A detection module is provided at the center of the end of the hollow cylinder facing the opening of the storage slot. An installation slot is provided at the end of the hollow cylinder away from the opening of the storage slot. A push-pull component that is powered by the elastic connection component is provided inside the installation slot.

[0007] Furthermore, the elastic connection assembly includes multiple fixed rods, both ends of which are fixedly connected to the inner wall of the storage groove, and the outer peripheral surfaces of the multiple fixed rods are slidably connected to a movable plate; multiple traction ropes are fixedly connected to one side of the movable plate; the inner wall of the storage groove is provided with multiple wire holes, each wire hole corresponding to a traction rope, so that each traction rope extends through the corresponding wire hole to the end of the rotating sleeve facing the smart dial.

[0008] Furthermore, the rotating sleeve has a connecting groove at one end facing the smart watch face, and the other ends of the multiple traction ropes extend into the rotating sleeve through the connecting groove and are fixedly connected to one end of the traction strap.

[0009] Furthermore, each of the fixed rods is fitted with a traction spring on its outer circumferential surface. One end of each traction spring is fixedly connected to the other side of the movable plate, and the other end is fixedly connected to the inner wall of the storage groove.

[0010] Furthermore, a connecting ring is fixedly connected to the inner wall of the storage slot, and multiple T-shaped rods are provided on the side of the connecting ring facing the moving plate. One end of each of the multiple T-shaped rods passes through the connecting ring and is fixedly connected to the hollow cylinder. A limiting spring is sleeved on the outer circumference of each T-shaped rod. One end of the limiting spring is fixedly connected to the protrusion of the corresponding T-shaped rod, and the other end is fixedly connected to the connecting ring.

[0011] Furthermore, a plug-in conductive sheet electrically connected to the detection module is fixedly connected to one end of the hollow cylinder facing the connecting ring; a through groove is provided on one side of the connecting ring so that the plug-in conductive sheet extends to the other side of the connecting ring through the through groove; elastic conductive sheets are slidably attached to both sides of the extended end of the plug-in conductive sheet, and both elastic conductive sheets are fixedly connected to the inner end wall of the receiving groove.

[0012] Furthermore, the push-pull assembly includes a connecting seat, which is fixedly installed on the side of the movable plate facing the connecting ring. A push-pull rod is rotatably connected inside the connecting seat. A push-pull plate is slidably connected inside the connecting seat. A push-pull groove is provided on one side of the push-pull plate, which is slidably connected to the push-pull rod. The push-pull groove includes a horizontal groove and an inclined groove, and the horizontal groove and the inclined groove are interconnected. Connecting rods are fixedly installed at both ends of the push-pull plate. Both connecting rods are fixedly installed on the inner wall of the hollow cylinder through mounting grooves.

[0013] The present invention has the following beneficial effects: 1. This invention, after the smart watch face is worn by the fixed strap and the traction strap, when the wearer engages in vigorous exercise, the traction strap, under external force, pulls the moving plate through the traction rope. The moving plate drives the push-pull rod from the horizontal groove into the inclined groove. At this time, the push-pull rod applies a pushing force to the hollow cylinder through the inclined groove and the push-pull plate, causing the hollow cylinder to compress the limiting spring through the T-shaped rod and gradually extend outward from the storage groove. Through the above settings, in the wearing state, the fixed strap and the traction strap do not need to fit too tightly against the wearer's wrist, thus ensuring wearing comfort. At the same time, when vigorous exercise causes the traction strap to slip under force, the detection module can automatically extend and fit against the skin, effectively avoiding the problem of interruption or significant distortion of health monitoring data caused by the detection module detaching from the skin or only contacting the skin with a large gap.

[0014] 2. This invention divides the push-pull groove into two parts: a horizontal groove and an inclined groove. This allows the sliding path of the push-pull rod to have a segmented adjustment function: when the wearer's movement is small, the push-pull rod only slides within the horizontal groove, and the hollow cylinder remains in contact with the connecting ring under the elastic force of the limiting spring, without displacement; only when the wearer's movement reaches a certain extent does the push-pull rod enter the inclined groove from the horizontal groove, driving the hollow cylinder to extend outward from the storage groove. In summary, through the cooperation of the horizontal groove and the inclined groove, the staged control of the push-pull rod's stroke is achieved, so that the extension action of the hollow cylinder is only triggered when the wearer makes a large-amplitude movement, avoiding frequent extension and retraction of the detection module due to the wearer's daily small movements.

[0015] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0021] Example 1 Please see Figures 1-10 As shown, the present invention is a wearable educational safety home-school information interaction device, including a smart watch face 1. Two rotating grooves are formed on the outer peripheral surface of the smart watch face 1, and the two rotating grooves are symmetrically distributed about the axis of the smart watch face 1. A rotating sleeve 3 is rotatably connected to one of the rotating grooves by a pivot pin. The rotating sleeve 3 is open at one end away from the smart watch face 1 and closed at the other end facing the smart watch face 1. A traction strap 4 is provided at the open end of the rotating sleeve 3, and the traction strap 4 is slidably connected to the rotating sleeve 3 through the opening. A fixed strap 2 is rotatably connected to the other rotating groove by a pivot pin.

[0022] The fixed watch band 2, away from the smart watch face 1, is rotatably connected to a buckle; the surface of the traction watch band 4 has multiple slots, and the buckle can engage with any of the slots to detachably and securely connect the traction watch band 4 and the fixed watch band 2, thereby allowing the smart watch face 1 to be worn on the user's wrist.

[0023] The bottom of the smart watch face 1 has a storage slot 5, and the inside of the storage slot 5 is an elastic connection component 6 that is connected to the traction strap 4. The elastic connection component 6 includes a movable plate 602 that is slidably connected inside the storage slot 5. Multiple traction ropes 603 are fixedly connected to one side of the movable plate 602. Multiple wire holes 604 are opened on the inner wall of the storage slot 5, and the multiple wire holes 604 correspond one-to-one with the multiple traction ropes 603.

[0024] The closed end of the rotating sleeve 3 is provided with a connecting groove 605, which is connected to the inner cavity of the rotating sleeve 3; each traction rope 603 passes through the corresponding wire hole 604 and connecting groove 605 in sequence and extends into the rotating sleeve 3, and is connected to the end face of the traction strap 4 provided inside the rotating sleeve 3. Multiple fixing rods 601 are fixedly connected inside the storage slot 5. Each fixing rod 601 is arranged parallel to the sliding direction of the traction strap 4. The moving plate 602 is slidably sleeved on each fixing rod 601. Under the guidance of the fixing rods 601, the moving plate 602 can slide back and forth along the length direction of the traction strap 4.

[0025] On the other side of the movable plate 602, there are multiple traction springs 606 that correspond one-to-one with the fixed rods 601. Each traction spring 606 is sleeved on the outer periphery of the corresponding fixed rod 601, and one end of the traction spring 606 is fixedly connected to the movable plate 602, and the other end is fixedly connected to the inner wall of the storage groove 5.

[0026] Under the elastic force of multiple traction springs 606, the moving plate 602 continuously pulls the traction strap 4 through the traction rope 603, so that the end of the traction strap 4 connected to the traction rope 603 is tightly fitted with the end wall of the rotating sleeve 3; when the smart watch face 1 is worn on the user's wrist, the elastic force of the traction springs 606 is transmitted to the traction strap 4, so that the traction strap 4 and the fixed strap 2 together apply a stable tightening force to the smart watch face 1, thereby ensuring the traction effect when worn.

[0027] Meanwhile, under the limiting action of the connecting groove 605, the multiple traction ropes 603 cannot pull the end of the traction strap 4 facing the smart dial 1 out of the rotating sleeve 3; at the same time, when the traction strap 4 moves to its maximum limit, it will not completely move out of the interior of the rotating sleeve 3, so that the rotating sleeve 3 can always block the multiple traction ropes 603.

[0028] In practical implementation, to balance the sealing performance at the wire hole 604 with the sliding flexibility of the traction rope 603, an O-ring can be embedded in the inner wall of the wire hole 604. The inner diameter of the O-ring is designed to be slightly smaller than the diameter of the traction rope 603, and the elastic deformation of the rubber achieves a tight grip on the rope, thereby forming an effective seal. At the same time, to meet the reciprocating sliding requirements of the traction rope 603, the O-ring is made of silicone or fluororubber with a low coefficient of friction, and its inner wall is coated with grease to significantly reduce sliding resistance and wear.

[0029] A connecting ring 11 is fixedly connected to the inner wall of the storage slot 5. A hollow cylinder 7 is provided on one side of the connecting ring 11 and is slidably connected to the storage slot 5. A plurality of T-shaped rods 12 are fixedly connected to one end of the hollow cylinder 7 facing the connecting ring 11. The plurality of T-shaped rods 12 slide through the connecting ring 11 so that the protruding part of the T-shaped rod 12 is on the other side of the connecting ring 11. A limiting spring 13 is sleeved on the outer circumference of each T-shaped rod 12. One end of the limiting spring 13 is fixedly connected to the protruding part of the T-shaped rod 12 and the other end is fixedly connected to the connecting ring 11.

[0030] Under the elastic force of the limiting spring 13, the T-shaped rod 12 drives the hollow cylinder 7 to move towards the connecting ring 11, so that the end face of the hollow cylinder 7 and the end face of the connecting ring 11 are tightly fitted, thereby ensuring that the hollow cylinder 7 remains stable when not subjected to external force and will not slide randomly in the storage groove 5.

[0031] A detection module 8 is embedded at the axis of one end of the hollow cylinder 7 away from the connecting ring 11; a plug-in conductive sheet 14 is fixedly connected to one end of the hollow cylinder 7 facing the connecting ring 11, and the plug-in conductive sheet 14 is electrically connected to the detection module 8 through an internal wire; a through groove 15 is opened on the connecting ring 11, and the plug-in conductive sheet 14 passes through the through groove 15 and extends to the other side of the connecting ring 11; elastic conductive sheets 16 are respectively attached and slidably attached to the opposite sides of the extension end of the plug-in conductive sheet 14, and both elastic conductive sheets 16 are fixedly installed on the inner wall of the storage groove 5, and both elastic conductive sheets 16 are electrically connected to the main control circuit board of the smart dial 1.

[0032] When the hollow cylinder 7 slides in the storage slot 5, the plug-in conductive sheet 14 moves synchronously with the hollow cylinder 7 and always maintains elastic contact with the two elastic conductive sheets 16 during the movement; so that the physiological signals collected by the detection module 8 during this process are transmitted to the main control circuit board in sequence through the plug-in conductive sheet 14 and the elastic conductive sheet 16, and after being processed by the main control circuit board, they are sent to the display screen of the smart dial 1 for display.

[0033] The hollow cylinder 7 has an installation groove 9 at one end facing the connecting ring 11. The installation groove 9 is provided with a push-pull assembly 10 that is powered by the elastic connecting assembly 6. The push-pull assembly 10 includes a connecting seat 101 fixedly connected to the side of the moving plate 602 facing the connecting ring 11, so that the connecting seat 101 is inside the installation groove 9. A push-pull rod 102 is rotatably connected inside the connecting seat 101.

[0034] The mounting slot 9 is equipped with a push-pull plate 103, which is located inside the connecting seat 101. Both ends of the push-pull plate 103 are fixedly installed with connecting rods 105, and the opposite ends of the two connecting rods 105 are fixedly installed on the end wall of the hollow cylinder 7. A push-pull groove 104 is provided on one side of the push-pull plate 103, and the push-pull rod 102 is slidably connected to the push-pull groove 104.

[0035] The push-pull groove 104 includes a horizontal groove and an inclined groove. The horizontal groove is parallel to the end face of the push-pull plate 103, and the inclined groove extends inclinedly from one end of the horizontal groove toward the connecting ring 11.

[0036] When the traction strap 4 and the fixed strap 2 are connected together by the buckle and the slot, as the traction strap 4 rotates, the traction rope 603 pulls the moving plate 602. At this time, the moving plate 602 moves under the guidance of multiple fixed rods 601 and pulls the traction spring 606, so that the traction strap 4 can rotate normally. In the above process, the moving plate 602 drives the push-pull rod 102 to slide inside the horizontal groove through the connecting seat 101, and the push-pull rod 102 will not move into the inclined groove, so that the hollow cylinder 7 remains in contact with the connecting ring 11 under the elastic force of the limiting spring 13 and does not produce displacement.

[0037] When the wearer engages in strenuous exercise, the traction strap 4 slides further under the action of external force, pulling the moving plate 602 through the traction rope 603. The moving plate 602 drives the push-pull rod 102 from the horizontal groove into the inclined groove through the connecting seat 101. As the push-pull rod 102 slides along the inclined groove, the push-pull rod 102 applies a pushing force to the hollow cylinder 7 through the push-pull plate 103. The hollow cylinder 7 compresses the limiting spring 13 through the T-shaped rod 12 and gradually extends outward from the storage groove 5.

[0038] With the above-mentioned horizontal and inclined grooves, when the wearer's movement is small, the push-pull rod 102 only slides along the horizontal groove, and the hollow tube 7 remains in the storage state; only when the movement reaches a certain level will the push-pull rod 102 enter the inclined groove, driving the hollow tube 7 to extend out from the storage groove 5.

[0039] Meanwhile, with the cooperation of the push-pull groove 104 and the push-pull rod 102, the elastic force of the traction spring 606 and the elastic force of the limit spring 13 work together on the traction rope 603, enhancing the traction effect of the traction rope 603 on the traction strap 4, so that the traction strap 4 remains stable when there is no significant external force, and will not slide freely in the rotating sleeve 3; and when the external force disappears, the traction strap 4 can automatically reset.

[0040] In practice, the outer surface of the hollow cylinder 7 is fitted with a sealing gasket made of silicone or polyurethane rubber. The sealing gasket fits tightly between the outer wall of the hollow cylinder 7 and the inner wall of the storage groove 5, effectively preventing external impurities from entering and ensuring a sliding sealing effect.

[0041] Meanwhile, the sealing gasket and the inner wall of the storage groove 5 generate a stable frictional force through a moderate interference fit, so that the hollow cylinder 7 will not retract immediately under the elastic force of the limiting spring 13, but will slowly reset after a certain delay. This damping characteristic ensures that even if the tension on the strap 4 changes frequently during vigorous exercise, the detection module 8 on the hollow cylinder 7 can still maintain a stable fit with the skin, thereby continuously and reliably collecting physiological signals.

[0042] Example 2 Please see Figures 11-13 As shown, in another embodiment of the present invention, the difference between Embodiment 2 and Embodiment 1 is that the traction rope 603 and the traction strap 4 are detachably connected, so that the user can replace or maintain the traction strap 4 separately according to the usage needs or wear conditions.

[0043] Both ends of the rotating sleeve 3 are open. A plug block 608 is slidably connected to the opening of the rotating sleeve 3 facing the smart dial 1. The plug block 608 is T-shaped and is fixedly connected to the other end of multiple traction ropes 603. The end of the traction strap 4 facing the smart dial 1 has a plug groove 607 that is engaged with the plug block 608.

[0044] One side of the plug block 608 has a through-hole 609, and the two sides of the traction strap 4 have corresponding connecting holes 610. A T-shaped plug rod 611 is inserted into both the plug hole 609 and the connecting hole 610. By inserting the plug block 608 into the plug groove 607, multiple traction ropes 603 are connected to the traction strap 4. Then, the T-shaped plug rod 611 is passed through the connecting hole 610 and the plug hole 609 in sequence to fix the plug block 608 in the plug groove 607, thereby ensuring that the traction strap 4 does not easily separate from the traction rope 603 when it pulls the traction rope 603.

[0045] The rotating sleeve 3 has sliding grooves 612 on both sides. One end of the T-shaped plug rod 611 extends to the outside of the rotating sleeve 3 through the sliding groove 612. A T-shaped sleeve 613 is fitted onto this end. A locking bolt 614 is inserted into the T-shaped sleeve 613. The locking bolt 614 is threadedly connected to the T-shaped plug rod 611. Through the sliding groove 612, the T-shaped plug rod 611 can pass through the rotating sleeve 3 and simultaneously pass through the connecting hole 610 and the plug hole 609, thereby passing through the traction strap 4 and the plug block 608. When the protrusion of the T-shaped plug rod 611 abuts against the side of the rotating sleeve 3, one end of the T-shaped plug rod 611 extends to the outside of the rotating sleeve 3. At this time, the T-shaped sleeve 613 is fitted onto this end and abuts against the side of the rotating sleeve 3. Then, the locking bolt 614 is screwed into this end of the T-shaped plug rod 611, thereby fixing the T-shaped sleeve 613 to this end.

[0046] The T-shaped connector 611 and the T-shaped sleeve 613 cooperate to form an I-shaped structure, which makes it difficult for the T-shaped connector 611 to come out of the sliding groove 612. When the traction strap 4 slides in the rotating sleeve 3, the rotating sleeve 3 can drive the T-shaped connector 611 to slide synchronously in the sliding groove 612. Under the limiting action of the sliding groove 612 and the T-shaped connector 611, the traction rope 603 will not come out of the rotating sleeve 3 under the pull of the traction strap 4, so that the rotating sleeve 3 can better cover the traction rope 603.

[0047] A limiting groove 615 is provided on the outer peripheral surface of the T-shaped plug rod 611. A limiting strip 616 is slidably connected in the limiting groove 615. The limiting strip 616 is fixedly connected to the inner wall of the T-shaped sleeve 613. When the T-shaped sleeve 613 is fitted onto the T-shaped plug rod 611, the limiting strip 616 is engaged in the corresponding limiting groove 615. With the cooperation of the limiting strip 616 and the limiting groove 615, the T-shaped sleeve 613 will not rotate relative to the T-shaped plug rod 611. Therefore, when the T-shaped plug rod 611 slides along the sliding groove 612, the T-shaped sleeve 613 will not drive the locking bolt 614 to rotate, ensuring that the locking bolt 614 locks the T-shaped sleeve 613 securely and reliably.

[0048] Working principle: By attaching the buckle to the appropriate slot, the fixed strap 2 is connected to the pull strap 4, thereby completing the wearing of the smart watch face 1. When worn, the traction strap 4 drives the rotating sleeve 3 to rotate in the corresponding rotating groove. As the traction strap 4 rotates, the traction rope 603 pulls the moving plate 602. At this time, the moving plate 602 moves under the guidance of multiple fixed rods 601 and pulls the traction spring 606. During the above process, the moving plate 602 drives the push-pull rod 102 to slide inside the horizontal groove through the connecting seat 101, and the push-pull rod 102 will not move into the inclined groove, so that the hollow cylinder 7 remains in contact with the connecting ring 11 under the elastic force of the limiting spring 13 and does not produce displacement. When the wearer engages in strenuous exercise, the traction strap 4 slides further under the action of external force, and the traction rope 603 pulls the moving plate 602. The moving plate 602 drives the push-pull rod 102 from the horizontal groove into the inclined groove through the connecting seat 101.

[0049] As the push-pull rod 102 slides along the inclined groove, the push-pull rod 102 applies a pushing force to the hollow cylinder 7 through the push-pull plate 103. The hollow cylinder 7 compresses the limiting spring 13 through the T-shaped rod 12 and gradually extends outward from the storage groove 5, so that the detection module 8 fits tightly against the wearer's wrist.

[0050] Meanwhile, as the hollow cylinder 7 slides within the storage groove 5, the inserted conductive sheet 14 moves synchronously with the hollow cylinder 7 and maintains elastic contact with the two elastic conductive sheets 16 throughout the movement.

[0051] When the detection module 8 collects physiological signals, the collected signals are transmitted to the main control circuit board in sequence through the plug-in conductive sheet 14 and the elastic conductive sheet 16. After being processed by the main control circuit board, the signals are sent to the display screen of the smart dial 1 for display.
