Description

Technical Field

[0001] This utility model relates to the field of charger technology, and in particular to a smartwatch charger. Background Technology

[0002] With the widespread adoption of smart wearable devices, smartwatches have become increasingly popular due to their convenience and multifunctionality. Charging is an essential part of using a smartwatch. Recharging relies on a smartwatch charger, which connects the smartwatch to the charger magnetically, transferring power from the charger to the smartwatch's battery.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: In actual use, existing smartwatch chargers that use magnetic attraction are prone to displacement or even detachment from the charger when the smartwatch is subjected to external collisions, vibrations, or other interference. This will interrupt the charging process, prolong the charging time, and may also cause local overheating due to poor contact, affecting the battery life and safety of the smartwatch. Therefore, a smartwatch charger is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing magnetic smartwatch chargers, where the smartwatch easily shifts and falls off the surface when subjected to impact or vibration. This not only interrupts charging and prolongs the charging time but also causes localized overheating due to poor contact, threatening battery life and safety. Therefore, this invention proposes a smartwatch charger.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a smart watch charger, comprising a charger body, a rotating shaft installed inside the charger body, a charging base rotatably connected to the arc surface of the rotating shaft, a socket installed on the surface of the charger body, a connector electrically connected inside the socket, a limiting device provided on the upper surface of the charging base, the limiting device comprising two mounting brackets, both of which are fixedly connected to the upper surface of the charging base, a sliding groove opened on the top surface of the inner wall of the mounting bracket, a sliding rod fixedly connected to the inner wall of the sliding groove, a slider slidably connected to the arc surface of the sliding rod, a first spring sleeved on the arc surface of the sliding rod, the two ends of the first spring being fixedly connected to the sliding groove and the slider respectively, a limiting block fixedly connected to the lower surface of the slider, and the limiting block being slidably connected to the inner wall of the mounting bracket.

[0006] The aforementioned components achieve the following effect: by setting a limiting device, the smartwatch being charged on the charging dock surface can be kept in place. When the smartwatch is placed on the charging dock surface, it presses against the limiting block, causing the limiting block to slide backward within the mounting bracket. During the movement of the limiting block, the slider moves along the sliding rod, compressing the first spring. Until the smartwatch contacts the charging dock surface, the first spring activates, causing the two limiting blocks to press and restrain the smartwatch from both sides, effectively preventing the smartwatch from detaching due to external interference during charging, thus ensuring that the smartwatch can charge normally.

[0007] Preferably, a plurality of balls are fixedly connected to the lower surface of the limiting block, the balls are slidably connected to the upper surface of the charging base, and the sides of the two limiting blocks that are close to each other are arc surfaces.

[0008] The effects achieved by the above components are as follows: the lower surface of the limiting block is equipped with ball bearings, which reduces the friction when it slides with the upper surface of the charging base, making the movement smoother; the side of the limiting blocks that is close to each other is designed with an arc surface, which can optimize the contact angle and force distribution between the smartwatch and the limiting block. The arc surface can effectively reduce contact resistance, allowing the smartwatch to push the limiting block to move and retract more smoothly.

[0009] Preferably, the lower end of the charger body is provided with a threaded groove, and a circular plate is slidably connected to the lower end of the charger body. A threaded rod is fixedly connected to one end of the circular plate near the charger body. The threaded rod is threadedly connected to the inner wall of the threaded groove, and a rubber pad is fixedly connected to one end of the circular plate away from the charger body.

[0010] The aforementioned components achieve the following effects: the rubber pad enhances the stability and anti-slip properties of the charger body when placed, preventing it from shifting due to accidental collisions or shaking during use, thus improving the stability of the charging process. Simultaneously, the engagement of the threaded rod and threaded groove allows for the replacement of rubber pads that have become damaged after prolonged use.

[0011] Preferably, the rubber pad has a plurality of strip grooves at the end away from the circular plate, and the plurality of strip grooves are arranged in a linear array.

[0012] The effects achieved by the above components are as follows: the groove can increase friction and enhance the stability of the charger body; at the same time, air can flow in the groove, avoiding adsorption caused by the rubber pad being too tightly attached to the placement surface.

[0013] Preferably, the surface of the charger body is provided with an auxiliary device, the auxiliary device including a fixing plate, the fixing plate being fixedly connected to the surface of the charger body, a fixing frame being fixedly connected to the surface of the charger body, a plurality of second springs being fixedly connected to the inner wall of the fixing frame, a clamping plate being fixedly connected to the other end of the plurality of second springs, the clamping plate being slidably connected to the inner wall of the fixing frame, and the clamping plate abutting against one side of the connector.

[0014] The effects achieved by the above components are as follows: by setting up an auxiliary device, the elasticity of the second spring in the auxiliary device allows the clamping plate to tightly hold the connector, effectively preventing the connector from loosening or falling off due to external pulling or shaking during use, thus enhancing connection stability. At the same time, when the connector is pulled out, the elasticity of the second spring will drive the clamping plate to slide forward and become a whole with the fixing plate, protecting the socket and preventing dust or impurities from entering, thereby improving the safety and reliability of the charger body.

[0015] Preferably, the upper surface of the fixing frame is provided with a sliding hole, and a round rod is slidably connected to the inner wall of the sliding hole, with one end of the round rod being fixedly connected to the clamping plate.

[0016] The above components achieve the following effects: when the connector needs to be inserted into the socket, the clamp can be moved by pulling the slide rod, providing the user with a point of force application. At the same time, the sliding guide structure formed by the sliding hole and the round rod can accurately limit the movement direction of the clamp and prevent the clamp from shifting or tilting during movement.

[0017] Preferably, the inner wall of the clamping plate is fixedly connected with a plurality of circular protrusions, and the plurality of circular protrusions are evenly distributed on the inner wall of the clamping plate.

[0018] The effect achieved by the above components is that the circular protrusion increases the frictional resistance between the clamp and the connector, which can more firmly clamp the connector and prevent it from loosening or falling off during use.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, a limiting device is used to limit the charging of a smartwatch on the charging dock surface. When the smartwatch is placed on the charging dock surface, it presses against the limiting block, causing the limiting block to slide backward within the mounting bracket. During the movement of the limiting block, the slider moves along the sliding rod, compressing the first spring. Until the smartwatch contacts the charging dock surface, the first spring activates, causing the two limiting blocks to press and limit the smartwatch from both sides, effectively preventing the smartwatch from detaching due to external interference during charging, thus ensuring normal charging.

[0021] 2. In this utility model, by setting an auxiliary device, the elasticity of the second spring in the auxiliary device is utilized to enable the clamping plate to tightly clamp the connector, effectively preventing the connector from loosening or falling off due to external pulling or shaking during use, thus enhancing connection stability. At the same time, when the connector is pulled out, the elasticity of the second spring will drive the clamping plate to slide forward and become a whole with the fixing plate, protecting the socket and preventing dust or impurities from entering, thereby improving the safety and reliability of the charger body.

[0030] Reference Figures 1-7As shown, this utility model provides a technical solution: a smartwatch charger, including a charger body 1, a rotating shaft 2 installed inside the charger body 1, a charging base 5 rotatably connected to the arc surface of the rotating shaft 2, a socket 6 installed on the surface of the charger body 1, a connector 7 electrically connected inside the socket 6, and a limiting device 3 provided on the upper surface of the charging base 5. By setting the limiting device 3, the smartwatch being charged on the surface of the charging base 5 can be limited. When the smartwatch is placed on the surface of the charging base 5, it will press the limiting block 306, causing the limiting block 306 to slide backward within the mounting bracket 301. During the movement of the limiting block 306, it drives the slider 304 to slide along the sliding rod 303, and compresses the first spring 305. Until the smartwatch contacts the surface of the charging base 5, the first spring 305 takes effect, causing the two limiting blocks 306 to press and limit the smartwatch from both sides, effectively preventing the smartwatch from detaching due to external interference during charging, thus ensuring that the smartwatch can charge normally. The surface of the charger body 1 is provided with an auxiliary device 4. By setting the auxiliary device 4, the elasticity of the second spring 43 in the auxiliary device 4 is used to make the clamping plate 44 tightly clamp the connector 7, effectively preventing the connector 7 from loosening or falling off due to external pulling or shaking during use, and enhancing the connection stability. At the same time, when the connector 7 is pulled out, the elasticity of its second spring 43 will drive the clamping plate 44 to slide forward and become a whole with the fixing plate 41, protecting the socket 6 and preventing dust or impurities from entering, thus improving the safety and reliability of the charger body 1.

[0031] The specific settings and functions of the limiting device 3 and the auxiliary device 4 will be explained in detail below.

[0032] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the limiting device 3 includes two mounting brackets 301, both of which are fixedly connected to the upper surface of the charging base 5. A groove 302 is formed on the top surface of the inner wall of the mounting bracket 301. A sliding rod 303 is fixedly connected to the inner wall of the groove 302. A slider 304 is slidably connected to the arc surface of the sliding rod 303. A first spring 305 is sleeved on the arc surface of the sliding rod 303. The two ends of the first spring 305 are fixedly connected to the groove 302 and the slider 304, respectively. A limiting block 306 is fixedly connected to the lower surface of the slider 304. The limiting block 306 is slidably connected to the inner wall of the mounting bracket 301. Several balls 307 are fixedly connected to the lower surface of the limiting block 306. The balls 307 are slidably connected to the upper surface of the charging base 5. The sides of the two limiting blocks 306 that are close to each other are arc-shaped. The balls 307 on the lower surface of the limiting block 306 allow them to contact the charging base 5. The friction is reduced when the upper surface of the charging base 5 slides, making the movement smoother. The limit blocks 306 are designed with an arc surface on the side closest to each other, which can optimize the contact angle and force distribution between the smartwatch and the limit block 306. The arc surface can effectively reduce contact resistance, allowing the smartwatch to push the limit block 306 to move and retract more smoothly. The lower end of the charger body 1 is provided with a threaded groove 308. A circular plate 309 is slidably connected to the lower end of the charger body 1. A threaded rod 310 is fixedly connected to the end of the circular plate 309 near the charger body 1. The threaded rod 310 is threadedly connected to the inner wall of the threaded groove 308. A rubber pad 311 is fixedly connected to the end of the circular plate 309 away from the charger body 1. The rubber pad 311 enhances the stability and anti-slip properties of the charger body 1 when placed, preventing the charger body 1 from shifting due to accidental collisions or shaking during use, and improving the stability of the charging process. Meanwhile, the engagement of the threaded rod 310 and the threaded groove 308 allows for the replacement of the rubber pad 311 that has been damaged after long-term use. The end of the rubber pad 311 away from the circular plate 309 has several strip grooves 312 arranged in a linear array. The strip grooves 312 can increase friction and enhance the stability of the charger body 1. At the same time, air can flow in the strip grooves 312 to prevent adsorption caused by the rubber pad 311 being too tightly attached to the placement surface.

[0033] Reference Figure 6 and Figure 7As shown, specifically, the auxiliary device 4 includes a fixing plate 41, which is fixedly connected to the surface of the charger body 1. A fixing frame 42 is fixedly connected to the surface of the charger body 1. Several second springs 43 are fixedly connected to the inner wall of the fixing frame 42. A clamping plate 44 is fixedly connected to the other end of the several second springs 43. The clamping plate 44 is slidably connected to the inner wall of the fixing frame 42 and abuts against one side of the connector 7. A sliding hole 45 is opened on the upper surface of the fixing frame 42. A round rod 46 is slidably connected to the inner wall of the sliding hole 45. One end of the round rod 46 is fixedly connected to the clamping plate 44. When it is necessary to connect the connector 7... When connector 7 is connected to socket 6, the clamping plate 44 can be moved by pulling the slide rod 303, providing a force application point for the user. At the same time, the sliding guide structure formed by the sliding hole 45 and the round rod 46 can accurately limit the movement direction of the clamping plate 44, preventing the clamping plate 44 from shifting or tilting during movement. Several circular protrusions 47 are fixedly connected to the inner wall of the clamping plate 44. The circular protrusions 47 are evenly distributed on the inner wall of the clamping plate 44. The circular protrusions 47 increase the frictional resistance between the clamping plate 44 and connector 7, which can more firmly clamp the connector 7 and prevent it from loosening or falling off during use.

[0034] Working principle: When the user places the smartwatch on the surface of the charging base 5, the two sides of the watch first contact the arc surface of the limiting block 306, causing the limiting block 306 to slide towards the inner wall of the mounting bracket 301. The limiting block 306 can slide with low friction against the surface of the charging base 5 through the ball bearings 307 on its lower surface. During the movement of the limiting block 306, it will drive the slider 304 to move smoothly along the slide rod 303. The slider 304 will compress the first spring 305 to store elastic potential energy. When the watch is fully seated for charging, the spring releases energy to drive the limiting block 306 to move in the opposite direction, precisely fitting the two sides of the watch to form a stable contact. At the same time, when it is necessary to prevent the lower end of the charger body 1 from sliding after placement, the circular plate 309 can be pushed to drive the threaded rod 310 to rotate and fix it in the threaded groove 308 until the circular plate 309 is in contact with the lower end of the charger body 1. The rubber pad 311 at the lower end of the circular plate 309 enhances the stability and anti-slip properties of the charger body 1 when placed. The grooves 312 on the surface of the rubber pad 311 prevent the vacuum adsorption effect, allowing the charger body 1 to be placed or removed quickly. When the rubber pad 311 is damaged and needs to be replaced, the circular plate 309 can be rotated to drive the threaded rod 310 to rotate in the threaded groove 308 until the threaded rod 310 moves away from the inner wall of the threaded groove 308, at which point the circular plate 309 and the rubber pad 311 can be disassembled and replaced.

[0035] When connector 7 needs to be connected to socket 6, the user pulls the round rod 46, causing the clamping plate 44 to move backward against the elastic force of several second springs 43. During this process, the sliding guide structure formed by the sliding hole 45 on the upper surface of the fixing frame 42 and the round rod 46 precisely restricts the movement direction of the clamping plate 44, preventing it from shifting or tilting during movement. After connector 7 is inserted into socket 6, the round rod 46 is released, and the second springs 43 push the clamping plate 44 forward with their own elastic potential energy. At this time, the evenly distributed circular protrusions 47 on the inner wall of the clamping plate 44 are in close contact with the surface of connector 7, firmly clamping connector 7 by increasing frictional resistance, effectively preventing it from loosening or falling off due to external pulling or shaking during use. When connector 7 is pulled out, the elastic force of the second spring 43 will continue to drive the clamp 44 to slide forward until it fits into the fixing plate 41 as a whole, thus forming a protective barrier for the socket 6 and preventing dust, impurities and other contaminants from entering the socket 6. While enhancing the connection stability, it further improves the safety and reliability of the charger body 1 and realizes full-process functional protection for connector 7 from clamping and fixing to idle protection.
