Description
Technical Field
[0001] The utility model relates to the technical field of charging devices, in particular to a wireless charger with automatic positioning. Background Art
[0002] A wireless charger is a device that uses the principle of electromagnetic induction to transmit electrical energy through magnetic field coupling between a transmitter and a receiver. Its principle is similar to that of a transformer. A coil is arranged at each of the transmitter and the receiver. The transmitter coil emits an electromagnetic signal to the outside under the action of electricity. The receiver coil receives the electromagnetic signal and converts it into an electric current, thereby realizing wireless charging. As a product of modern technology, the wireless charger has brought great convenience to people's work and life. The wireless charging technology can provide a convenient charging method and solve the cumbersome problem of charging cables.
[0003] In the prior art, when a user uses a wireless charger, the situation that the mobile phone is placed with an offset or rotation often occurs, which results in the inability to achieve the maximum energy transmission efficiency. Due to improper placement, the user needs to adjust the position of the mobile phone multiple times, which not only increases the power consumption but also reduces the user experience. The wireless charger has specific requirements for the placement position of the mobile phone. Especially when there are no visible alignment marks on both the charger and the mobile phone, it is very difficult for the user to place the mobile phone accurately at one time during use. Once it is found that the charging efficiency is poor or charging cannot be achieved, the user often needs to interrupt the current activity and adjust the position of the mobile phone, which is an obvious interruption for users who pursue a smooth experience. The design of the wireless charger does not consider the user-friendliness and lacks an auxiliary alignment mechanism, which increases the difficulty for the user to place the mobile phone correctly. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art and propose a wireless charger with automatic positioning.
[0005] To achieve the above object, the utility model adopts the following technical solution: An automatically positioned wireless charger, comprising a device main body, a charging area is provided at the top of the device main body, a power cord is provided at the back of the device main body, an installation groove is opened at the top of the device main body, an L-shaped fixing plate is fixed to the inner wall of the installation groove, a driving link is rotatably connected to one side of the L-shaped fixing plate, one end of the driving link is rotatably connected to a trapezoidal bearing plate, a top support plate is fixed to the top of the trapezoidal bearing plate, a positioning limit plate is fixed to the top of the top support plate, a driven link is rotatably connected to one side of the L-shaped fixing plate, one end of the driven link is rotatably connected to one side of the trapezoidal bearing plate, a long hanging rod is fixed to one side of the L-shaped fixing plate, a locking spring is fixed to the circumferential surface of the long hanging rod, the other end of the locking spring is fixed to a short hanging rod, one end of the short hanging rod is fixed to one side of the trapezoidal bearing plate, a fixing groove is opened at the top of the device main body, a starting motor is fixed to the inner wall of the fixing groove, and the driving link is driven by the starting motor. In the prior art, when a user uses a wireless charger, the situation that the placement position of the mobile phone is offset or rotated often occurs, which results in the inability to achieve the maximum energy transmission efficiency. Due to improper placement, the user needs to adjust the position of the mobile phone multiple times, which not only increases the power consumption but also reduces the user experience. The wireless charger has specific requirements for the placement position of the mobile phone. Especially when there are no visible alignment marks on both the charger and the mobile phone, it is very difficult for the user to place the mobile phone accurately at one time when using it. Once it is found that the charging efficiency is poor or charging cannot be carried out, the user often needs to interrupt the current activity and adjust the position of the mobile phone, which is an obvious interruption for users who pursue a smooth experience. The design of the wireless charger does not consider the user-friendliness and lacks an auxiliary alignment mechanism, which increases the difficulty for the user to place the mobile phone correctly. To solve such problems, the utility model adopts the method of installing a positioning limit plate. When the user places the mobile phone on the top of the device main body, the starting motor is started, driving the driving link to rotate clockwise, and at the same time, the driven link rotates clockwise accordingly, the locking spring is stretched, the trapezoidal bearing plate, the top support plate and the positioning limit plate rise. Due to the components being subjected to the pulling force of the locking spring, the positioning limit plate rotates counterclockwise and tilts. The positioning limit plates on both sides of the top of the device main body rotate and tilt towards the charging area, causing the mobile phone at the offset position to slide towards the charging area and be positioned. At the same time, restricted by the positioning limit plate, the direction of the mobile phone is also adjusted forward, so that it maintains a proper position for charging, achieving the effect of improving the user experience.
[0006] Preferably, an inner arc groove is formed on the side surface of the device body. A fixing member is fixed to the inner wall of the inner arc groove. One end of the fixing member is fixed with a fixed-end member. A wire groove is formed on one side of the fixed-end member. The inner wall of the wire groove is nested with the surface of the power cord. In the prior art, the wires on the back of the wireless charger are prone to bending and breaking during repeated use, resulting in device damage. This not only affects the charging effect but also may bring unnecessary troubles and additional maintenance costs to users. The physical material of the wire will produce material fatigue after repeated bending. Especially the outer insulation protection layer of the wire is prone to cracks or breaks after multiple bends, resulting in the exposure of the internal wire, increasing the risk of short circuit or electric leakage. To solve such problems, the present utility model adopts the method of installing a fixed-end member, realizing that the fixed-end member can effectively prevent the power cord from being continuously bent at the connection with the device during use, thus avoiding the problems of breakage and damage, ensuring a more stable and reliable connection between the power cord and the device, reducing the damage risk caused by wire bending, not only improving the durability of the device but also extending the service life of the power cord, bringing a better user experience to users and achieving the effect of improving the service life of the device.
[0007] Preferably, an LED auxiliary lamp is fixed to the top of the device body. In the prior art, when users use the wireless charger at night, due to the relatively dim ambient light, it is difficult to find the charging position well, resulting in a reduced user experience. Users need to spend more time and energy to find the correct charging position. To solve such problems, the present utility model adopts the method of installing an LED auxiliary lamp, realizing that when the mobile phone approaches the charging area of the device body, an electromagnetic field is generated and the LED auxiliary lamp lights up, facilitating the user to place the mobile phone and achieving the effect of improving the user experience.
[0008] Preferably, a rice-shaped bracket is fixed to the top of the device body. The user can place the mobile phone on the rice-shaped bracket for easy use, improving the user experience and increasing the applicable range of the device.
[0009] Preferably, a triangular fixing member is fixed to one side of the trapezoidal bearing plate. The top of the triangular fixing member is fixed to the bottom of the top support plate, improving the stability between components and the service life of the device.
[0010] Preferably, a rubber strip is fixed to the top end of the inner wall of the fixing groove, reducing the friction between components and improving the service life of the device.
[0011] Preferably, a rubber pad is fixed to the bottom of the device body, increasing the friction between the device and the desktop and improving the stability of the device.
[0012] Beneficial effects:
[0013] 1. In the prior art, when a user uses a wireless charger, it often happens that the placement position of the mobile phone is offset or rotated, which results in the inability to achieve the maximum energy transfer efficiency. Due to improper placement, the user needs to adjust the position of the mobile phone multiple times, which not only increases the power consumption but also reduces the user experience. The wireless charger has specific requirements for the placement position of the mobile phone. Especially when there are no visible alignment marks on both the charger and the mobile phone, it is very difficult for the user to place the mobile phone accurately at one time when using it. Once it is found that the charging efficiency is poor or charging is impossible, the user often needs to interrupt the current activity and adjust the position of the mobile phone, which is an obvious interruption for users who pursue a smooth experience. The design of the wireless charger does not take into account the user-friendliness and lacks an auxiliary alignment mechanism, which increases the difficulty for the user to place the mobile phone correctly. To solve such problems, the present utility model adopts the method of installing a positioning limit plate. When the user places the mobile phone on the top of the device main body, the motor is started, driving the driving connecting rod to rotate clockwise. At the same time, the driven connecting rod rotates clockwise accordingly, and the locking spring is stretched. The trapezoidal bearing plate, the top support plate, and the positioning limit plate rise. Due to the components being subjected to the tensile force of the locking spring, the positioning limit plate rotates counterclockwise and tilts. The positioning limit plates on both sides of the top of the device main body rotate and tilt towards the charging area, causing the mobile phone at the offset position to slide towards the charging area and be positioned. At the same time, restricted by the positioning limit plate, the direction of the mobile phone is also adjusted to be forward, so that it maintains a proper position for charging, achieving the effect of improving the user experience.
[0014] 2. In the prior art, the wires on the back of the wireless charger are prone to bending and breaking during multiple uses, resulting in device damage. This not only affects the charging effect but also may bring unnecessary troubles and additional maintenance costs to the user. The physical material of the wire will produce material fatigue after repeated bending. Especially the insulating protective layer on the outer layer of the wire is prone to cracks or breaks after multiple bends, resulting in the exposure of the internal conductors and increasing the risk of short circuit or electric leakage. To solve such problems, the present utility model adopts the method of installing a fixed-end piece. The fixed-end piece can effectively prevent the power cord from being continuously bent at the connection with the device during use, thus avoiding the problems of fracture and damage, ensuring a more stable and reliable connection between the power cord and the device, reducing the damage risk caused by wire bending, not only improving the durability of the device but also extending the service life of the power cord, bringing a better use experience to the user, and achieving the effect of improving the service life of the device.
[0015] 3. In the prior art, when a user uses a wireless charger at night, due to the relatively dim ambient light, it is difficult to find the charging position well, resulting in a reduced user experience. The user needs to spend more time and energy to find the correct charging position. To solve such problems, the present utility model adopts the method of installing an LED auxiliary lamp. When the mobile phone approaches the charging area of the device main body, an electromagnetic field is generated, and the LED auxiliary lamp lights up, facilitating the user to place the mobile phone, achieving the effect of improving the user experience.

However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.
[0024] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific Embodiment:
[0026] Refer to Figures 1-5, a wireless charger with automatic positioning, including a device main body 1. There is a charging area 101 at the top of the device main body 1, a power cord 102 at the back of the device main body 1, and an installation groove 2 is opened at the top of the device main body 1. An L-shaped fixing plate 201 is fixed on the inner wall of the installation groove 2. One side of the L-shaped fixing plate 201 is rotatably connected to a driving connecting rod 202. One end of the driving connecting rod 202 is rotatably connected to a trapezoidal bearing plate 203. A top support plate 204 is fixed on the top of the trapezoidal bearing plate 203. A positioning limit plate 205 is fixed on the top of the top support plate 204. One side of the L-shaped fixing plate 201 is rotatably connected to a driven connecting rod 206. One end of the driven connecting rod 206 is rotatably connected to one side of the trapezoidal bearing plate 203. One side of the L-shaped fixing plate 201 is fixed with a long hanging rod 207. A locking spring 208 is fixed on the circumferential surface of the long hanging rod 207. The other end of the locking spring 208 is fixed with a short hanging rod 209. One end of the short hanging rod 209 is fixed to one side of the trapezoidal bearing plate 203. A fixing groove 2011 is opened at the top of the device main body 1. A starting motor 2010 is fixed on the inner wall of the fixing groove 2011. The driving connecting rod 202 is driven by the starting motor 2010. When the user uses the wireless charger, the situation of the mobile phone being placed in an offset or rotated position often occurs, which results in the inability to achieve the maximum energy transfer efficiency. Due to improper placement, the user needs to adjust the position of the mobile phone multiple times, which not only increases the power consumption but also reduces the user experience. The wireless charger has specific requirements for the placement position of the mobile phone. Especially when there are no visible alignment marks on both the charger and the mobile phone, it is very difficult for the user to place the mobile phone accurately in place at one time when using it. Once it is found that the charging efficiency is poor or charging cannot be achieved, the user often needs to interrupt the current activity and adjust the position of the mobile phone, which is an obvious disturbance to users who pursue a smooth experience. The design of the wireless charger does not consider user ease of use and lacks an auxiliary alignment mechanism, which increases the difficulty for the user to place the mobile phone correctly. It is solved by adopting the method of installing the positioning limit plate 205. When the user places the mobile phone on the top of the device main body 1, the starting motor 2010 is started, driving the driving connecting rod 202 to rotate clockwise. At the same time, the driven connecting rod 206 rotates clockwise accordingly, and the locking spring 208 is stretched. The trapezoidal bearing plate 203, the top support plate 204, and the positioning limit plate 205 rise. Due to the components being pulled by the locking spring 208, the positioning limit plate 205 rotates counterclockwise and tilts. The positioning limit plates 205 on both sides of the top of the device main body 1 rotate and tilt towards the charging area 101, causing the mobile phone in the offset position to slide towards the charging area 101 and be positioned. At the same time, restricted by the positioning limit plate 205, the direction of the mobile phone is also adjusted forward to keep it in a proper position for charging, achieving the effect of improving the user experience. A triangular fixing piece 5 is fixed on one side of the trapezoidal bearing plate 203. The top of the triangular fixing piece 5 is fixed to the bottom of the top support plate 204 to improve the stability between components and extend the service life of the device. A rubber strip 501 is fixed at the top end of the inner wall of the fixing groove 2011 to reduce the friction between components and extend the service life of the device.
[0027] On the side of the device main body 1, an inner arc groove 402 is provided. A fixing member 3 is fixed to the inner wall of the inner arc groove 402. One end of the fixing member 3 is fixed with a fixed-end member 301. A wire groove 302 is provided on one side of the fixed-end member 301. The inner wall of the wire groove 302 is nested with the surface of the power cord 102. During repeated use, the wires on the back of the wireless charger are prone to bending and breaking, resulting in device damage. This not only affects the charging effect but also may bring unnecessary trouble and additional maintenance costs to users. The physical material of the wires will experience material fatigue after repeated bending, especially the outer insulating protective layer of the wires, which is prone to cracks or breaks after multiple bends, resulting in the exposure of the internal conductors and increasing the risk of short circuit or electric leakage. The problem is solved by installing the fixed-end member 301, which enables the fixed-end member 301 to effectively prevent the power cord 102 from being continuously bent at the connection with the device during use, thus avoiding the problems of breakage and damage. This can ensure a more stable and reliable connection between the power cord 102 and the device, reduce the damage risk caused by wire bending, not only improve the durability of the device but also extend the service life of the power cord 102, bringing a better user experience and achieving the effect of improving the service life of the device. An LED auxiliary lamp 4 is fixed to the top of the device main body 1. When the user uses the wireless charger at night, due to the relatively dim ambient light, it is difficult to better locate the charging position, resulting in a reduced user experience. The user needs to spend more time and energy to find the correct charging position. The problem is solved by installing the LED auxiliary lamp 4, which enables the LED auxiliary lamp 4 to light up when the mobile phone approaches the charging area 101 of the device main body 1, generating an electromagnetic field, facilitating the user to place the mobile phone and achieving the effect of improving the user experience. A hexahedral bracket 401 is fixed to the top of the device main body 1. The user can place the mobile phone on the hexahedral bracket 401 for convenient use, improving the user experience and increasing the applicable range of the device. A rubber pad 403 is fixed to the bottom of the device main body 1 to increase the friction between the device and the desktop and improve the stability of the device.
[0028] Working principle of the present utility model: When the user places the mobile phone on the top of the device main body 1, the motor 2010 is started, driving the driving connecting rod 202 to rotate clockwise. At the same time, the driven connecting rod 206 rotates clockwise accordingly, and the locking spring 208 is stretched. The trapezoidal bearing plate 203, the top support plate 204, and the positioning limiting plate 205 rise. Due to the component being subjected to the tensile force of the locking spring 208, the positioning limiting plate 205 rotates counterclockwise and inclines. The positioning limiting plates 205 on both sides of the top of the device main body 1 rotate and incline towards the charging area 101, causing the mobile phone at the offset position to slide towards the charging area 101 and be positioned. At the same time, restricted by the positioning limiting plate 205, the direction of the mobile phone is also adjusted to be forward, enabling it to maintain a proper position for charging.
