Description

Technical Field

[0001] This invention relates to the field of watch movements, specifically to a smartwatch and its movement structure. Background Technology

[0002] Currently, smartwatches use wired or wireless charging methods. Wireless charging isn't truly wireless; instead, it uses magnetic attachment to fix the watch to a charging dock. However, this method isn't very effective, and the watch movement can easily slip off due to insufficient magnetism. Charging via a charging port often compromises the movement's water and dust resistance. Adding a rubber plug to the charging port would directly affect the smartwatch's aesthetics. Therefore, there's a need for a smartwatch that can effectively improve dust and water resistance without compromising aesthetics. Summary of the Invention

[0003] This invention provides a smartwatch and its movement structure, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A smartwatch movement structure includes a movement comprising a housing and a movement body, characterized in that the housing and the movement body are fixed by an adjustment mechanism disposed therebetween, the movement body is movably mounted within the housing, the movement body has a function adjustment button and a charging port on its side, the inner end face of the housing near the function adjustment button has an inwardly recessed adjustment groove, and a spherical rotating shaft is installed in the adjustment groove, the surface of the spherical rotating shaft has a through hole, and the function adjustment button extends out of the housing through the through hole;

[0006] The lower edge of the outer shell is provided with a flat surface for the movement of the main body of the mechanism to swing downwards, and the downward swing angle of the main body of the mechanism is 0°~20°. When the main body of the mechanism is pushed downwards, the main body of the mechanism swings downwards with the spherical pivot as the fulcrum until the charging port is no longer blocked by the outer shell, and then the charging cable is connected.

[0007] The adjustment mechanism includes an electromagnetic connector disposed within the main body of the movement and a repulsion structure disposed within the outer shell, with the electromagnetic connector and the repulsion structure disposed close to each other.

[0008] The electromagnetic connector has an arch-shaped structure and is composed of multiple conductive strips. The adjacent ends of two adjacent conductive strips do not abut against each other, and the adjacent ends of two adjacent conductive strips are connected by an electromagnetic post. The electromagnetic post passes through and connects the adjacent ends of two adjacent conductive strips. Both ends of the electromagnetic connector are connected to conductive coils. The two conductive coils are connected to a miniature relay, and the miniature relay is connected to a power source to control the current conduction of the electromagnetic connector.

[0009] The repulsion structure includes various mounting slots disposed on the inner surface of the outer shell. Each mounting slot corresponds to a specific electromagnetic post. The mounting slot is provided with a positioning post and a limiting protrusion. The limiting protrusion is disposed on the side of the mounting slot close to the electromagnetic post, and the positioning post is disposed on the side of the mounting slot away from the limiting protrusion and extends toward the limiting protrusion. The positioning post is covered with a sliding magnetic block and a spring. The sliding magnetic block is connected to the surface of the mounting slot through the spring.

[0010] A preferred technical solution is that the inner end face of the outer casing is provided with an outwardly protruding rubber protrusion near the charging port. When the main body of the mechanism is installed in the outer casing, the rubber protrusion is embedded in the charging port and abuts against the charging port.

[0011] In a preferred embodiment, the upper inner surface of the outer casing abuts against the movement body, while there is a gap between the lower inner surface of the outer casing and the outer casing, and a sealing ring extending towards the center of the outer casing is provided at the lower outer edge of the outer casing, which covers and abuts against the surface of the movement body.

[0012] In a preferred technical solution, the adjacent ends of two adjacent conductive strips are staggered, and the electromagnetic post is perpendicular to the surface of the conductive strip and protrudes from the surface of the mechanism body. When the electromagnetic connector is in the current conducting state, the electromagnetic post is embedded in the mounting groove.

[0013] A preferred technical solution is that one end of each side of the conductive strip is provided with a bent portion that bends away from the repulsion structure, and the bent portions provided on two adjacent conductive strips face the same direction.

[0014] A preferred technical solution is that the electromagnetic column includes a conductive hollow column and a sliding column disposed inside the conductive hollow column. The circumferential surface of the sliding column is provided with an outwardly protruding stepped edge and a movable magnetic block. The stepped edge is disposed on the inner surface of the sliding column, while the movable magnetic block is disposed on the outer surface of the sliding column.

[0015] The conductive hollow column passes through one of the conductive strips and abuts against the bent part of the other conductive strip. When the conductive hollow column is installed on the conductive strip, the movable magnetic block is positioned closer to the repulsion structure than the conductive strip and the step edge. When the electromagnetic connector current is not conducting, the sliding column does not protrude from the surface of the conductive hollow column. When the electromagnetic connector current is conducting, the current magnetic poles on the surface of the conductive strip are opposite to the magnetic poles of the movable magnetic block, repelling the movable magnetic block outward, causing it to protrude from the surface of the movement body and be embedded in the mounting groove.

[0016] In a preferred embodiment, the magnetic poles of the sliding magnetic block are opposite to those of the movable magnetic block. When the current in the electromagnetic connector is not conducting, the spring pushes the sliding magnetic block outward, and the sliding magnetic block pushes the movable magnetic block back into the movement body.

[0017] In a preferred embodiment, the cross-section of the electromagnetic connector is arc-shaped, and the bending angle is consistent with the side angle of the movement body.

[0018] A smartwatch, including the movement structure of the smartwatch.

[0019] Compared with existing technologies, this technical solution has the following advantages:

[0020] This invention achieves reliable fixation between the movement body and the outer shell through the cooperation of electromagnetic connectors and a repulsion structure, without requiring an exposed charging port or a rubber plug. In the non-charging state, current conduction causes the movable magnetic block to embed into the mounting groove, ensuring a stable fit between the movement body and the outer shell, effectively sealing the charging port and improving the overall dust and water resistance. Simultaneously, the absence of exposed interfaces or additional plugs maintains the overall aesthetic appeal. When charging is needed, disconnecting the current releases the magnetic fixation, allowing the movement body to swing downwards and expose the charging port. This solution avoids the problem of unstable fixation with traditional magnetic bases and also avoids the sealing defects caused by long-term exposure of physical interfaces.

[0039] like Figures 1 to 11 As shown, the present invention proposes a movement structure for a smartwatch, including a movement 100 having an outer shell 1 and a movement body 2. The outer shell 1 and the movement body 2 are fixed by an adjustment mechanism provided therebetween. The movement body 2 is movably installed inside the outer shell 1. The movement body 2 has a function adjustment button 21 and a charging port 22 on its side. The inner end face of the outer shell 1 has an inwardly recessed adjustment groove 11 near the function adjustment button 21, and a spherical rotating shaft 13 is installed in the adjustment groove 11. The surface of the spherical rotating shaft 13 has a through hole, and the function adjustment button 21 extends to the outside of the outer shell 1 through the through hole.

[0040] The lower edge of the outer casing 1 has a flat surface for the mechanism body 2 to swing downwards. The downward swing angle of the mechanism body 2 is 0°~20°. When the mechanism body 2 is pushed downwards, it swings downwards around the spherical pivot 13 until the charging port 22 is no longer blocked by the outer casing 1, at which point the charging cable can be connected. When the user needs to charge, the mechanism body 2 can be manually pushed downwards to swing downwards around the spherical pivot 13, thereby exposing the charging port 22, which was originally blocked by the outer casing 1, for easy connection of the charging cable. This structure differs from the fixed charging port design or the method of wireless charging relying on a magnetic base in the prior art. In the prior art, if an exposed charging port is used, it needs to be exposed to the outside for a long time, affecting the waterproof and dustproof performance; if a rubber cover is used, it affects the appearance. This solution, through the swingable mechanism structure, allows the charging port 22 to be covered by the outer casing 1 when not charging, improving the sealing and overall appearance consistency; the charging port is only temporarily exposed when charging is needed, balancing functionality and protection.

[0041] The adjustment mechanism includes an electromagnetic connector 23 disposed in the main body 2 of the movement and a repulsion structure 14 disposed in the outer shell 1, with the electromagnetic connector 23 and the repulsion structure 14 disposed close to each other.

[0042] The electromagnetic connector 23 has an arch-shaped structure and is composed of multiple conductive strips 231. The adjacent ends of two adjacent conductive strips 231 do not abut against each other, and the adjacent ends of two adjacent conductive strips 231 are connected by an electromagnetic post 232. The electromagnetic post 232 passes through and connects the adjacent ends of two adjacent conductive strips 231. Both ends of the electromagnetic connector 23 are connected to conductive coils 233. The two conductive coils 233 are connected to a miniature relay 234, and the miniature relay 234 is connected to a power source to control the current conduction of the electromagnetic connector 23.

[0043] Furthermore, the repulsion structure 14 includes various mounting grooves 141 disposed on the inner surface of the outer shell 1. Each mounting groove 141 corresponds to a respective electromagnetic post 232. The mounting groove 141 is provided with a positioning post 142 and a limiting protrusion 145. The limiting protrusion 145 is disposed on the side close to the electromagnetic post 232. The positioning post 142 is disposed on the side of the mounting groove 141 away from the limiting protrusion 145 and extends toward the limiting protrusion 145. The positioning post 142 is covered with a sliding magnetic block 143 and a spring 144. The sliding magnetic block 143 is connected to the surface of the mounting groove 141 through the spring 144.

[0044] Furthermore, the adjacent ends of the two adjacent conductive strips 231 are staggered, and the electromagnetic post 232 is perpendicular to the surface of the conductive strip 231. The electromagnetic post 232 protrudes from the surface of the main body 2. When the electromagnetic connector 23 is in the current conducting state, the electromagnetic post 232 is embedded in the mounting groove 141.

[0045] The electromagnetic column 232 includes a conductive hollow column 2321 and a sliding column 2322 disposed within the conductive hollow column 2321. The circumferential surface of the sliding column 2322 is provided with an outwardly protruding stepped edge 2323 and a movable magnetic block 2324. The stepped edge 2323 is disposed on the surface of the sliding column 2322 located within 2321, while the movable magnetic block 2324 is disposed on the surface of the sliding column 2322 not located within 2321. The magnetic poles of the sliding magnetic block 143 are opposite to those of the movable magnetic block 2324. When the current of the electromagnetic connector 23 is not conducted, the spring 144 pushes the sliding magnetic block 143 outward, and the sliding magnetic block 143 pushes the movable magnetic block 2324 back into the movement body 2.

[0046] Furthermore, one end of each side of the conductive strip 231 is provided with a bent portion that bends away from the repulsion structure 14. The bent portions on two adjacent conductive strips 231 face the same direction. The conductive hollow column 2321 passes through one of the conductive strips 231 and abuts against the bent portion of the other conductive strip 231. When the conductive hollow column 2321 is installed on the conductive strip 231, the movable magnetic block 2324 is positioned closer to the repulsion structure 14 than the conductive strip 231 and the step edge 2323. When the current of the electromagnetic connector 23 is not conducting, the sliding column 2322 does not protrude from the surface of the conductive hollow column 2321. When the current of the electromagnetic connector 23 is conducting, the current magnetic poles on the surface of the conductive strip 231 are opposite to the magnetic poles of the movable magnetic block 2324, repelling the movable magnetic block 2324 outward, causing it to protrude from the surface of the movement body 2 and be embedded in the mounting groove 141.

[0047] In this design, two adjacent conductive strips 231 are connected by a conductive hollow column 2321 within the electromagnetic post 232. The conductive hollow column 2321 passes through one of the conductive strips 231 and abuts against the bent portion of the other conductive strip 231, thus achieving both mechanical and electrical connection between adjacent conductive strips 231. When the micro relay 234 controls the current to flow, the current flows sequentially through the conductive coil 233, the conductive strip 231, and the conductive hollow column 2321, forming a closed loop in the entire electromagnetic connector 23. At this time, a magnetic field is generated around the conductive strip 231. This magnetic field is opposite to the magnetic pole of the movable magnetic block 2324 on the sliding post 2322, thus generating a repulsive force. In this process, the conductive hollow column 2321 not only serves as part of the conductive path, ensuring the smooth flow of current to stimulate the magnetic effect, but also acts as the mounting carrier for the sliding post 2322, providing guidance and support. Therefore, the conductive hollow column 2321 plays a key role in structural connection, current conduction and magnetic force transmission, and is the core component for realizing the controlled ejection of the movable magnetic block 2324.

[0048] As described above, when the smartwatch is in normal power supply mode and does not require charging, the micro relay 234 conducts current, allowing the current to flow through the conductive coil 233 into the bow-shaped electromagnetic connector 23. The current flows through each conductive strip 231 and generates a magnetic field around it. Since the movable magnetic block 2324 is set to have the opposite polarity to the magnetic field generated by the conductive strip 231, a magnetic repulsion force is formed between them, pushing the slide column 2322 to slide outward along the conductive hollow column 2321, causing the movable magnetic block 2324 to protrude from the outer surface of the movement body 2 and embed into the corresponding mounting groove 141 inside the outer casing 1, forming a fixed position.

[0049] When the watch's battery is depleted or the system actively cuts off the power supply, the miniature relay 234 disconnects the circuit, no current flows through the electromagnetic connector 23, the conductive strip 231 no longer generates a magnetic field, and the magnetic repulsion disappears. At this time, the spring 144 in the repulsion structure 14 comes into play: one end of the spring 144 is connected to the bottom surface of the mounting groove 141, and the other end is connected to the sliding magnetic block 143. It is always in a compressed or pre-tightened state when the current is not conducting. Once the magnetic repulsion is released, the spring 144 releases its elastic potential energy, pushing the sliding magnetic block 143 outward along the positioning post 142, causing it to move towards the movement body 2. Since both the sliding magnetic block 143 and the movable magnetic block 2324 are made of magnetic materials and their magnetic poles repel each other, the outward movement of the sliding magnetic block 143 will exert a reverse repulsive force on the movable magnetic block 2324, forcing the sliding post 2322 to overcome its own friction or slight resistance and retract into the conductive hollow post 2321, thereby causing the movable magnetic block 2324 to completely retract into the movement body 2 and escape the constraint of the mounting groove 141.

[0050] Therefore, in the absence of power, the fixation between the movement body 2 and the outer shell 1 is automatically released. The user can directly push the movement body 2 downwards, causing it to swing around the spherical pivot 13 to expose the charging port 22, without the need for additional unlocking mechanism operation. This mechanism ensures that the device can still be easily put into charging mode even when it is completely out of power, solving the problem that traditional magnetic or mechanical locks cannot be released after power failure, thus improving user experience and structural reliability.

[0051] Compared to the issues of slippage in magnetic wireless charging and the impact of wired charging ports on waterproofing, dustproofing, and appearance mentioned in the background art, this invention achieves reliable fixation between the main body 2 and the outer shell 1 through the cooperation of the electromagnetic connector 23 and the repulsion structure 14, without the need for an exposed charging port or rubber plug. In the non-charging state, current conduction causes the movable magnet 2324 to embed into the mounting groove 141, ensuring the main body 2 stably adheres to the outer shell 1, effectively sealing the charging port 22 and improving the overall dustproof and waterproof performance. Simultaneously, the absence of exposed interfaces or additional plugs maintains the overall integrity and aesthetics of the device. When charging is needed, disconnecting the current releases the magnetic fixation, allowing the main body 2 to swing downwards and expose the charging port 22. This solution avoids the problem of unstable fixation in traditional magnetic bases and also avoids the sealing defects caused by long-term exposure of physical interfaces, thus structurally resolving the technical contradictions pointed out in the background art.

[0052] In order to further improve the tightness of the connection between the outer shell 1 and the main body 2 of the movement and the sealing of the charging port 22, the inner end face of the outer shell 1 of the present invention is provided with an outwardly protruding rubber protrusion 15 near the charging port 22. When the main body 2 of the movement is installed in the outer shell 1, the rubber protrusion 15 is embedded in the charging port 22 and abuts against the charging port 22.

[0053] Furthermore, the upper inner surface of the outer casing 1 abuts against the movement body 2, while there is a gap between the lower inner surface of the outer casing 1 and the outer casing 1. A sealing ring 12 extending towards the middle of the outer casing 1 is provided at the lower outer edge of the outer casing 1, and the sealing ring 12 covers and abuts against the surface of the movement body 2.

[0054] In a preferred embodiment, the electromagnetic connector 23 has an arc-shaped cross-section, and the bending angle is consistent with the side angle of the movement body 2.

[0055] The present invention also provides a smartwatch, including the movement structure of the smartwatch.

[0056] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
