Description

Technical Field

[0001] The present invention relates to the technical field of power adapters, and more specifically, to a power adapter for electronic devices. Background Art

[0002] With the progress of technology, electronic devices such as mobile phones have become necessities in people's lives. Power adapters are usually used to charge electronic devices such as mobile phones. In daily use scenarios, as a key component for powering electronic devices, power adapters are extremely widely used. Whether in indoor home environments or outdoor mobile scenarios, users often need to carry power adapters to ensure the continuous operation of electronic devices and replenish electrical energy for the devices at any time; For example, in the power adapter and electronic device assembly with the Chinese patent publication number CN112886311B, the cover is connected to the adapter body and is movable relative to the adapter body. When the cover is in the closed state, the pins can be protected from being damaged and other objects can be prevented from being damaged by the pins. When the power adapter needs to be used, the cover is opened to expose the pins. Further, the second end face of the cover and the first end face of the adapter body jointly form the plug-in face of the power adapter. In other words, the first end face of the adapter body only constitutes a part of the plug-in face of the power adapter, and the thickness of the adapter body can be made thinner, which is conducive to the miniaturization of the power adapter; Considering that there are many socket brands on the market and there are differences in the structural designs of different brand sockets, due to the structural characteristics of some socket products, when users insert the power adapter plug into the socket jack, they need to apply a large external force to effectively connect the power adapter to the socket and establish a power supply connection. Moreover, with the widespread use of power strips in modern life, when using a power strip to supply power to an electronic device, during the process of inserting the power adapter, users need to first firmly hold the power strip by hand to prevent it from moving due to external force, and then accurately and stably insert the power adapter plug into the power strip jack to ensure a reliable electrical connection between the power adapter and the power strip. When using a power adapter in different scenarios, users need to spend extra energy and effort to deal with socket differences and power strip fixation. Summary of the Invention

[0003] The purpose of the present invention is to provide a power adapter for electronic devices, which solves the problems that there are numerous and various socket brands on the market, some socket jacks are relatively tight, users need to apply force to effectively connect when inserting the power adapter plug, and in daily life, power strips are mostly used for power supply. When inserting, users not only have to insert with effort but also have to first stabilize the power strip to prevent it from moving before accurately inserting the plug into the jack to ensure a reliable electrical connection. When using a power adapter in different scenarios, extra energy and effort are required to deal with these situations.

[0004] To achieve the above object, the present invention provides a power adapter for an electronic device, including an electronic adapter body. A connector is fixedly connected to the top of the electronic adapter body. An auxiliary insertion component is provided on the surface of the connector. A roller 2201 structure is provided inside the auxiliary insertion component, which is used to contact the surface of the socket when the connector is inserted into the socket and slide along the outer wall of the connector to reduce the frictional resistance. An auxiliary extraction component is provided in the inner cavity of the electronic adapter body, and a fixing component is arranged at its bottom. A groove matching with the fixing component is provided on the inner wall of the electronic adapter body. When the auxiliary insertion component slides along the connector to a predetermined position, its bottom abuts against the auxiliary extraction component, driving the auxiliary extraction component to move axially and accumulate elastic restoring force. The fixing component rotates with the movement of the auxiliary extraction component, and when the auxiliary extraction component moves to a set stroke, the fixing component will be clamped into the groove to limit the further displacement of the auxiliary extraction component. One of its purposes is that when the connector is inserted into the socket, the surface of the auxiliary insertion component contacts the surface of the socket, driving the auxiliary insertion component to slide downward. The roller makes it easier to insert the auxiliary insertion component when it cooperates with the connector insertion. When the connector is completely inserted into the inner wall of the socket, the bottom of the auxiliary insertion component gradually inserts into the inner cavity of the auxiliary extraction component, causing the auxiliary extraction component to slide downward and generate a downward elastic force. At the same time, the auxiliary extraction component drives the fixing component to rotate and be stuck in the inner cavity of the groove, thereby fixing the auxiliary extraction component so that it will not slide upward. And during the contact process between the connector and the socket, the elastic force in the auxiliary extraction component is blocked from being released. When the fixing component is separated from the groove and the electronic adapter body is pulled, the upward elastic force of the auxiliary extraction component is released, and the connector is pulled out of the socket in cooperation with the electronic adapter body.

[0005] As a further improvement of this technical solution, the auxiliary insertion component includes a connecting plate that slides on the surface of the connector. A limiting slide bar is fixedly connected to the bottom of the connecting plate. The surface of the limiting slide bar slides on the inner wall of the electronic adapter body. The contact surface between the connecting plate and the socket is made of rubber. A slide rail is fixedly connected to the inner wall of the inner cavity of the electronic adapter body. A chute is opened in the inner wall of the slide rail. A connecting column is fixedly connected to the end of the limiting slide bar away from the connecting plate. A roller is fixedly connected to the bottom of the connecting column. The surface of the roller slides on the inner wall of the chute. The second purpose is that the limiting slide bar cooperates with the chute of the slide rail on the inner wall of the inner cavity of the electronic adapter body through the roller at the bottom of the connecting column, converting the original sliding friction between the limiting slide bar and the inner wall of the electronic adapter body into the rolling friction of the roller in the chute. This change in the friction method significantly reduces the resistance when the auxiliary insertion component slides downward. When the user inserts the power adapter, there is no need to apply a large external force, and the connector can be easily pushed into the socket, greatly reducing the operation burden, which is especially friendly to users with less strength.

[0006] As a further improvement of the technical solution, the auxiliary pulling-out component includes a support frame fixedly connected to the inner cavity of the electronic adapter body. One end of the roller away from the connecting column is fixedly connected with a connecting rod. The support frame is located below the connecting rod. A rotating column is rotatably connected to the inner wall of the support frame. A sliding column is slidably connected to the inner wall of the rotating column. A damper is fixedly connected to the inner cavity of the sliding column. The top of the damper contacts the end of the connecting rod. The surface of the connecting rod slides in the inner cavity of the sliding column. A limiting rod is fixedly connected to the surface of the damper. An annular groove is formed on the surface of the rotating column. The annular groove is arranged around the outer surface of the rotating column and extends from the top to the bottom of the rotating column. The surface of the limiting rod slides on the inner wall of the annular groove; Therefore, a further beneficial effect is obtained that during the insertion process of the connector, the damper in the auxiliary pulling-out component contracts under the pressing of the connecting rod and stores elastic potential energy. When it is necessary to pull out the connector, the damper releases the stored elastic force, providing additional power support for the pulling-out operation, greatly reducing the force required for the user to pull out the plug and making the pulling-out process easier and smoother.

[0007] As a further improvement of the technical solution, a through groove is formed on the surface of the support frame. The rotating column rotates on the inner wall of the through groove. The fixing component includes a rotating rod fixedly connected to the bottom of the rotating column. One end of the rotating rod away from the rotating column is fixedly connected with a cross bar. A fixing frame is fixedly connected to the inner wall of the groove. An arc-shaped groove is formed on the surface of the fixing frame, and the shape of the arc-shaped groove is adapted to the surface of the cross bar for connection; This solution further supplements the effect. The support frame is fixed in the inner cavity of the electronic adapter body, providing a stable support basis for the rotating column. The through groove formed on its surface plays a guiding role in the rotation of the rotating column, limiting the rotation path of the rotating column and ensuring that the rotating column can rotate smoothly on the inner wall of the support frame around a specific axis. The fixing component is connected to the rotating column through the rotating rod and the cross bar. When the rotating column rotates, it can drive the rotating rod and the cross bar to rotate synchronously. The cross bar closely cooperates with and is clamped to the arc-shaped groove on the surface of the fixing frame on the inner wall of the groove during the rotation process. This clamping structure effectively prevents the reverse rotation of the rotating column.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the power adapter for electronic devices, the contact surface between the connecting plate of the auxiliary insertion component and the socket is made of rubber material. At the moment when the connector is inserted into the socket, relying on the softness and friction of the rubber, it can effectively buffer the impact force, provide reliable grip, and prevent the electronic adapter from slipping or shifting during the insertion process; By setting a connecting column and rollers at one end of the limiting slide rod and cooperating with the slide rail and the chute on the inner wall of the main cavity of the electronic adapter, the sliding friction between the limiting slide rod and the slide rail is converted into the rolling friction of the rollers in the chute, significantly reducing the resistance when the auxiliary insertion component slides down. Users only need to apply a small force to push the connector into the socket, greatly reducing the operation burden, which is especially user-friendly for users with less strength.

[0009] 2. In the power adapter for electronic devices, the rotation of the rotating column is stopped by the clamping connection between the cross bar and the fixing bracket. When the user needs to pull out the main body of the electronic adapter, first, the clamping connection state between the cross bar and the fixing bracket needs to be released. Once the clamping connection is released, the rotating column that was originally restricted from rotating regains its rotational freedom. Just by applying a force to pull out the main body of the electronic adapter, the compressed damper will quickly release the stored elastic force, pushing the sliding column to slide upward along the inner wall of the rotating column. The upward movement of the sliding column then generates a strong thrust on the connecting rod. This thrust combines with the force applied by the user to pull out the main body of the electronic adapter outward to form a resultant force, helping the user easily pull the connector out of the socket.

[0011] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0012] Please refer to Figures 1-9 As shown in the figure, this embodiment provides a power adapter for an electronic device, including an electronic adapter main body 100. A connector 110 is fixedly connected to the top of the electronic adapter main body 100. A roller 2201 structure is provided on the surface of the connector 110, which is used to contact the surface of the socket when the connector 110 is inserted into the socket and slide along the outer wall of the connector 110 to reduce the frictional resistance; An auxiliary extraction component 300 is provided in the inner cavity of the electronic adapter main body 100, and a fixing component 400 is arranged at its bottom. A groove 1001 is provided on the inner wall of the electronic adapter main body 100 and is matched with the fixing component 400; When the auxiliary insertion component 200 slides along the connector 110 to a predetermined position, its bottom abuts against the auxiliary extraction component 300, driving the auxiliary extraction component 300 to move axially and accumulate elastic restoring force; The fixing component 400 rotates with the movement of the auxiliary extraction component 300, and when the auxiliary extraction component 300 moves to a set stroke, the fixing component 400 will be clamped into the groove 1001 to limit the further displacement of the auxiliary extraction component 300; Considering that there are many socket brands on the market, there are differences in the structural design of sockets of different brands. Due to the structural characteristics of some socket products, users need to apply a large external force when inserting the power adapter plug into the socket jack, so that the power adapter and the socket can be effectively plugged in to establish a power supply connection. In addition, in modern life, plug strips are widely used. When using the plug strip to power electronic devices, users need to first use their hands to stabilize the plug strip when plugging in the power adapter to prevent the plug strip from being displaced due to external force, and then accurately and stably insert the power adapter plug into the socket of the plug strip to ensure a reliable electrical connection between the power adapter and the plug strip. When users use the power adapter in different scenarios, they need to spend extra energy and physical strength to deal with the differences in sockets and the fixation of the plug strip. Therefore, the auxiliary insertion component 2 is used. 00 is provided with a roller 2201. When the connector 110 is inserted into the socket, the rolling of the roller 2201 can effectively reduce the friction between the auxiliary insertion component 200 and the connector 110 and the surface of the socket, which means that the user can easily insert the connector 110 into the socket without using much force, which significantly reduces the difficulty of insertion, and is more friendly to people with less strength, such as children and the elderly. When the connector 110 is inserted into the socket, the auxiliary insertion component 200 slides downward and contacts the auxiliary extraction component 300, causing the auxiliary extraction component 300 to slide downward to generate elastic force, and at the same time drives the fixing component 400 to rotate and get stuck in the groove 1001, thereby fixing the auxiliary extraction component 300 so that it will not slide upward, and in the process of the connector 110 contacting the socket, the elastic force in the auxiliary extraction component 300 is blocked from being released.

[0013] At the same time, considering that in actual use, it often takes a lot of force to pull the connector 110 out of the socket, which brings inconvenience to the user. Therefore, during the entire period when the connector 110 is connected to the socket, the elastic force generated by the auxiliary extraction component 300 is in a suppressed state. Once the user needs to pull out the connector 110, he only needs to release the lock between the fixing component 400 and the groove 1001, and at the same time apply an initial external force to the outside. After this operation, the elastic force of the auxiliary extraction component 300 that was originally blocked will be immediately released. This released elastic force is combined with the outward pulling force applied by the user to form a powerful combined force. With this combined force, even if dealing with a socket with extremely high plugging and unplugging resistance, the connector 110 can be easily pulled out of the socket, making the unplugging process smooth and labor-saving, which completely changes the previous situation of laborious unplugging of the plug.

[0014] On the basis of the above, the specific structure is disclosed in detail: In order to enable the auxiliary insertion component 200 to have its surface contact the socket surface when the connector 110 is inserted, and to be slidably connected to the surface of the connector 110 during this process, it is necessary to further disclose the parts of the auxiliary insertion component 200. Therefore, the auxiliary insertion component 200 includes a connecting plate 210 that slides on the surface of the connector 110. A limiting slide bar 2101 is fixedly connected to the bottom of the connecting plate 210, and the surface of the limiting slide bar 2101 slides on the inner wall of the electronic adapter body 100; The contact surface between the connecting plate 210 and the socket is made of rubber; When the user holds the electronic adapter body 100 and aligns the connector 110 with the socket for insertion, the first part to contact the socket is the connecting plate 210. Since the contact surface between the connecting plate 210 and the socket is made of rubber, this material has a certain softness and friction, which can provide good buffering and grip at the moment of contacting the socket, preventing the electronic adapter from slipping or shifting during insertion. As the insertion progresses further, the socket exerts an upward force on the connecting plate 210, causing the connecting plate 210 to drive the limiting slide bar 2101 fixedly connected to its bottom to slide downward along the inner wall of the electronic adapter body 100, so that the inner wall of the connecting plate 210 slides on the surface of the connector 110.

[0015] In order to make the limiting slide bar 2101 slide on the inner wall of the electronic adapter body 100, the roller 2201 structure of the auxiliary insertion component 200 can make the limiting slide bar 2101 slide more easily. It is necessary to disclose other components of the auxiliary insertion component 200. Therefore, a slide rail 230 is fixedly connected to the inner wall of the cavity of the electronic adapter body 100, and a chute 2301 is opened on the inner wall of the slide rail 230; A connecting column 220 is fixedly connected to the end of the limiting slide bar 2101 away from the connecting plate 210, and a roller 2201 is fixedly connected to the bottom of the connecting column 220; The surface of the roller 2201 slides on the inner wall of the chute 2301; when the connecting plate 210 contacts the socket surface, at this time the socket will exert an upward force on the connecting plate 210, causing the connecting plate 210 to drive the limiting slide bar 2101 fixedly connected to it to move, so that the connecting column 220 and the roller 2201 at the other end of the limiting slide bar 2101 will slide in the chute 2301 opened on the slide rail 230 fixedly connected to the inner wall of the cavity of the electronic adapter body 100. The roller 2201 rolls in the chute 2301, converting the possible sliding friction between the original limiting slide bar 2101 and the slide rail 230 into rolling friction, greatly reducing the resistance when the auxiliary insertion component 200 slides downward. This enables the auxiliary insertion component 200 to slide more smoothly along the surface of the connector 110 downward, and the user only needs to apply a smaller force to push the connector 110 into the socket, easily achieving the insertion function.

[0016] Considering that the auxiliary insertion component 200 will gradually abut against the auxiliary extraction component 300 when moving downward, a connecting rod 240 is fixedly connected to the end of the roller 2201 away from the connecting column 220. The auxiliary extraction component 300 is located below the connecting rod 240. When the roller 2201 slides in the inner cavity of the chute 2301, it will drive the connecting rod 240 to move vertically downward and gradually approach the auxiliary extraction component 300 until it abuts against the auxiliary extraction component 300.

[0017] Considering that when the connecting rod 240 gradually moves vertically downward, the auxiliary extraction component 300 will move downward in cooperation with the connecting rod 240, it is necessary to further disclose the parts of the auxiliary extraction component 300. Therefore, the auxiliary extraction component 300 includes a support frame 310 fixedly connected to the inner cavity of the electronic adapter body 100. A rotating column 320 is rotatably connected to the inner wall of the support frame 310. A sliding column 330 is slidably connected to the inner wall of the rotating column 320. A damper 3301 is fixedly connected to the inner cavity of the sliding column 330. The top of the damper 3301 contacts the end of the connecting rod 240, and the surface of the connecting rod 240 slides in the inner cavity of the sliding column 330. First, when the connecting rod 240 moves downward, it will insert into the inner cavity of the sliding column 330 and contact the top of the damper 3301. With the continuous downward movement of the connecting rod 240, the damper 3301 will contract. When the damper 3301 can no longer contract, the damper 3301 will drive the sliding column 330 to slide downward on the inner wall of the rotating column 320. When the sliding column 330 slides downward on the inner wall of the rotating column 320, it will drive the rotating column 320 to rotate on the inner wall of the support frame 310.

[0018] In order to enable the rotating column 320 to rotate on the inner wall of the support frame 310 when the sliding column 330 moves downward, a limiting rod 3302 is fixedly connected to the surface of the damper 3301. An annular groove 3201 is formed on the surface of the rotating column 320. The annular groove 3201 is arranged around the outer surface of the rotating column 320 and extends from the top to the bottom of the rotating column 320. The surface of the limiting rod 3302 slides on the inner wall of the annular groove 3201. When the auxiliary extraction component 300 operates, when the connecting rod 240 is driven by the auxiliary insertion component 200 to move downward, it contacts the top of the damper 3301 and continues to press down. The damper 3301 contracts and drives the connected limiting rod 3302. Since the limiting rod 3302 is slidably connected in the annular groove 3201 on the surface of the rotating column 320, during the contraction of the damper 3301, the limiting rod 3302 can only move along the track of the groove in the annular groove 3201.

[0019] In order to enable the rotating column 320 to drive the fixed component 400 to rotate when rotating, a through groove is provided on the surface of the support frame 310, the rotating column 320 rotates on the inner wall of the through groove, and the bottom of the rotating column 320 is connected to the end of the fixed component 400; the rotation of the rotating column 320 can drive the fixed component 400 to rotate synchronously.

[0020] In order to enable the fixed component 400 to rotate in cooperation with the rotating column 320, it is necessary to further disclose the parts of the fixed component 400. Therefore, the fixed component 400 includes a rotating rod 410 fixedly connected to the bottom of the rotating column 320, and a cross bar 420 is fixedly connected to the end of the rotating rod 410 away from the rotating column 320; the rotation of the rotating column 320 can drive the rotating rod 410 to rotate synchronously, and the rotation of the rotating rod 410 can drive the cross bar 420 to rotate synchronously.

[0021] In order to enable the fixed component 400 to be clamped with the groove 1001, a fixed frame 430 is fixedly connected to the inner wall of the groove 1001, and an arc groove is provided on the surface of the fixed frame 430, and the shape of the arc groove is adaptively connected to the surface of the cross bar 420; during the rotation of the rotating column 320, it can drive the rotating rod 410 connected thereto to rotate, and then drive the cross bar 420 to rotate. When the cross bar 420 rotates, its outer surface will gradually approach the fixed frame 430 on the inner wall of the groove 1001 until the cross bar 420 is in close fit with the arc groove on the surface of the fixed frame 430 to complete the clamping action, thereby realizing the stable clamping of the fixed component 400 and the groove 1001, thereby preventing the rotating column 320 from rotating in the reverse direction and causing the damper 3301 to push the connecting rod 240 upward.

[0022] In summary, the working process of the present invention: As Figures 2-3 When the connector 110 is not inserted into the socket, it is the state distribution when the auxiliary insertion component 200 and the auxiliary extraction component 300 are not working. As Figures 4-7 When the connector 110 is inserted into the socket, it is the working state when the auxiliary insertion component 200 slides on the surface of the connector 110 and the auxiliary extraction component 300 moves downward to drive the fixed component 400 to be clamped. First, hold the handheld electronic adapter body 100 and bring the connector 110 close to the socket. When the user holds the handheld electronic adapter body 100 and aligns the connector 110 with the socket for insertion, the first part to contact the socket is the connection plate 210. When the connection plate 210 contacts the surface of the socket, the socket will apply an upward force to the connection plate 210, causing the connection plate 210 to drive the limit slide bar 2101 fixedly connected thereto to move. As a result, the connection column 220 and the roller 2201 at the other end of the limit slide bar 2101 will slide within the chute 2301 opened in the slide rail 230 fixed to the inner wall of the cavity of the handheld electronic adapter body 100. The roller 2201 rolls within the chute 2301, converting the possible sliding friction between the original limit slide bar 2101 and the slide rail 230 into rolling friction, greatly reducing the resistance when the auxiliary insertion assembly 200 slides downward. The downward movement of the roller 2201 can drive the connecting rod 240 at its bottom to move downward. When the connecting rod 240 is driven by the auxiliary insertion assembly 200 to move downward and contacts the top of the damper 3301 and continuously presses down, the damper 3301 contracts, driving the limit rod 3302 connected thereto. Since the limit rod 3302 is slidably connected within the annular groove 3201 on the surface of the rotating column 320, during the contraction process of the damper 3301, the limit rod 3302 can only move along the trajectory of the groove within the annular groove 3201. The rotation of the rotating column 320 can synchronously drive the rotation of the rotating rod 410, and the rotation of the rotating rod 410 can synchronously drive the rotation of the cross bar 420. When the cross bar 420 rotates, its outer surface will gradually approach the fixed bracket 430 on the inner wall of the groove 1001 until the cross bar 420 is in close fit with the arc-shaped groove on the surface of the fixed bracket 430, completing the clamping action, thereby realizing the stable clamping of the fixing assembly 400 and the groove 1001.
