Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power adapter, in particular to a power adapter for electronic device. BACKGROUND

[0002] With the progress of technology, electronic devices such as mobile phones have become necessities of life, and power adapters are usually used to charge electronic devices such as mobile phones. In daily use scenarios, power adapters are key components for supplying power to electronic devices, and are widely used. Whether it is an indoor home environment or a mobile scenario, users often need to carry power adapters to ensure the continuous operation of electronic devices and supplement the power of the devices at any time.

[0003] For example, the power adapter and electronic device assembly disclosed in Chinese Patent No. 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 damage and other objects can be protected from damage by the pins. When the power adapter is needed, 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 together form the plug-in face of the power adapter. In other words, the first end face of the adapter body only constitutes part of the plug-in face of the power adapter. The thickness of the adapter body can be made thinner, thereby facilitating the miniaturization of the power adapter.

[0004] Considering the numerous brands of sockets on the market, different brands of sockets have structural differences. Due to the structural characteristics of some socket products, users need to apply a large external force to insert the power adapter plug into the socket socket, so that the power adapter and the socket can be effectively plugged in to establish a power supply connection. In modern life, the use of power strips is widespread. When using a power strip to power an electronic device, the user needs to first stabilize the power strip with their hand to avoid displacement of the power strip due to external forces, and then accurately and stably insert the power adapter plug into the power strip socket. In this way, a reliable electrical connection is formed between the power adapter and the power strip. Users need to expend additional effort and physical strength to deal with socket differences and power strip fixation when using the power adapter in different scenarios. SUMMARY

[0005] The power adapter for electronic equipment aims to solve the problems of various socket brands, different structures, tight socket jacks, and the need for force to achieve effective connection when inserting the power adapter plug, and the need for extra effort and physical strength to cope with these conditions when using the power adapter in different scenarios.

[0006] To achieve the above-mentioned purpose, the power adapter for electronic equipment comprises an electronic adapter main body, a connector fixedly connected to the top of the electronic adapter main body, and an auxiliary insertion assembly provided on the surface of the connector, wherein the auxiliary insertion assembly is internally provided with a roller structure 2201 for contacting the surface of the socket when the connector is inserted into the socket and sliding along the outer wall of the connector to reduce the frictional resistance.

[0007] The inner cavity of the electronic adapter main body is provided with an auxiliary pulling-out assembly, the bottom of which is provided with a fixing assembly, and the inner wall of the electronic adapter main body is provided with a groove matched with the fixing assembly.

[0008] When the auxiliary insertion assembly slides along the connector to a predetermined position, the bottom thereof abuts against the auxiliary pulling-out assembly, driving the auxiliary pulling-out assembly to move axially and accumulate elastic restoring force.

[0009] The fixing assembly rotates with the movement of the auxiliary pulling-out assembly, and when the auxiliary pulling-out assembly moves to a set stroke, the fixing assembly is clamped into the groove to limit the further displacement of the auxiliary pulling-out assembly.

[0010] One of the purposes is that when the connector is inserted into the socket, the surface of the auxiliary insertion assembly contacts the surface of the socket, driving the auxiliary insertion assembly to slide downward, and the roller makes the auxiliary insertion assembly more labor-saving when the connector is inserted, and when the connector is completely inserted into the inner wall of the socket, the bottom of the auxiliary insertion assembly is gradually inserted into the inner cavity of the auxiliary pulling-out assembly, driving the auxiliary pulling-out assembly to slide downward and generate downward elastic force, and at the same time, the auxiliary pulling-out assembly drives the fixing assembly to rotate and clamp in the inner cavity of the groove, thereby fixing the auxiliary pulling-out assembly so that it cannot slide upward, and in the process of the connector contacting the socket, the elastic force in the auxiliary pulling-out assembly is blocked, when the fixing assembly is separated from the groove and the electronic adapter main body is pulled out, the upward elastic force of the auxiliary pulling-out assembly is released, and the connector is pulled out of the socket in cooperation with the electronic adapter main body.

[0011] As a further improvement of the technical solution, the auxiliary insertion assembly comprises a connecting plate sliding on the joint surface, the bottom of the connecting plate is fixedly connected with a limiting slide rod, the surface of the limiting slide rod slides on the inner wall of the electronic adapter body, the contact surface of the connecting plate and the socket is made of rubber material, the inner wall of the inner cavity of the electronic adapter body is fixedly connected with a slide rail, the inner wall of the slide rail is provided with a sliding groove, the end of the limiting slide rod away from the connecting plate is fixedly connected with a connecting column, the bottom of the connecting column is fixedly connected with a roller, and the surface of the roller slides on the inner wall of the sliding groove;

[0012] The second purpose is to convert the sliding friction between the limiting slide rod and the inner wall of the electronic adapter body into rolling friction of the roller in the sliding groove through the cooperation of the roller at the bottom of the connecting column and the sliding groove of the slide rail on the inner wall of the inner cavity of the electronic adapter body, which significantly reduces the resistance when the auxiliary insertion assembly slides down, and the user can easily push the joint into the socket without applying a large external force when inserting the power adapter, greatly reducing the operation burden, especially for users with less strength.

[0013] As a further improvement of the technical solution, the auxiliary insertion assembly comprises a connecting plate sliding on the joint surface, the bottom of the connecting plate is fixedly connected with a limiting slide rod, the surface of the limiting slide rod slides on the inner wall of the electronic adapter body, the contact surface of the connecting plate and the socket is made of rubber material, the inner wall of the inner cavity of the electronic adapter body is fixedly connected with a slide rail, the inner wall of the slide rail is provided with a sliding groove, the end of the limiting slide rod away from the connecting plate is fixedly connected with a connecting column, the bottom of the connecting column is fixedly connected with a roller, and the surface of the roller slides on the inner wall of the sliding groove;

[0014] Therefore, further beneficial effects are obtained, the damper in the auxiliary pulling-out assembly is contracted by the depression of the connecting rod during the joint insertion process, storing elastic potential energy, when the joint needs to be pulled out, the damper releases the stored elastic force, providing additional power support for the pulling-out operation, greatly reducing the strength required by the user to pull out the plug, making the pulling-out process more comfortable and smooth.

[0015] As a further improvement of the technical solution, the surface of the support frame is provided with a through groove, the rotating column rotates in the inner wall of the through groove, the fixing assembly comprises a rotating rod fixedly connected to the bottom of the rotating column, the end of the rotating rod away from the rotating column is fixedly connected with a horizontal rod, the inner wall of the groove is fixedly connected with a fixing frame, and the surface of the fixing frame is provided with an arc-shaped groove, the shape of the arc-shaped groove is matched with the surface of the horizontal rod.

[0016] The scheme further supplements the effect, the support frame is fixed in the inner cavity of the electronic adapter main body, provides a stable support basis for the rotating column, the through slot opened on the surface of the support frame plays a guiding role in the rotation of the rotating column, limits the rotating path of the rotating column, ensures that the rotating column can stably rotate on the inner wall of the support frame around a specific axis, and the fixing assembly is connected with the rotating column through the rotating rod and the cross rod, when the rotating column rotates, the rotating rod and the cross rod can be driven to synchronously rotate, the cross rod is tightly matched with the arc-shaped groove on the surface of the fixed frame in the rotating process and is clamped, and the clamping structure effectively prevents the rotating column from rotating in the opposite direction.

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] 1. In the power adapter for electronic equipment, the contact surface between the connecting plate of the auxiliary insertion assembly and the socket is made of rubber material, and at the moment when the connector is inserted into the socket, the softness and friction of the rubber can effectively buffer the impact force, provide reliable grip, and prevent the electronic adapter from slipping or deviating during insertion.

[0019] By setting the connecting column and the roller at one end of the limiting slide rod, and matching the slide rail and the sliding groove on the inner wall of the inner cavity of the electronic adapter main body, the sliding friction between the limiting slide rod and the slide rail is converted into the rolling friction of the roller in the sliding groove, which significantly reduces the resistance when the auxiliary insertion assembly slides down, and the user only needs to exert a small force to push the connector into the socket, greatly reducing the operation burden, especially for users with less strength.

[0020] 2. In the power adapter for electronic equipment, the clamping of the cross rod and the fixed frame makes the rotating column stop rotating, when the user needs to pull out the electronic adapter main body, the clamping state between the cross rod and the fixed frame is first released, once the clamping is released, the rotating column which was originally limited to rotate restores the freedom of rotation, only by adding a force to pull out the electronic adapter main body, the compressed damper will quickly release the stored elastic force, push the slide column to slide upward along the inner wall of the rotating column, the upward movement of the slide column further generates a strong pushing force on the connecting rod, and the pushing force and the force exerted by the user to pull out the electronic adapter main body combine to form a resultant force, helping the user to easily pull out the connector from the socket.

[0034] DETAILED DESCRIPTION The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0035] EMBODIMENTS Please refer to

[0036] Figures 1-9 ​​As shown, the embodiment provides a power adapter for electronic equipment, comprising an electronic adapter body 100, a connector 110 is fixedly connected to the top of the electronic adapter body 100, an auxiliary insertion assembly 200 is arranged on the surface of the connector 110, and a roller 2201 structure is arranged in the auxiliary insertion assembly 200, 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;

[0037] An auxiliary pulling-out assembly 300 is arranged in the inner cavity of the electronic adapter body 100, and a fixing assembly 400 is arranged at the bottom of the auxiliary pulling-out assembly 300, and a groove 1001 is arranged on the inner wall of the electronic adapter body 100 and matched with the fixing assembly 400;

[0038] When the auxiliary insertion assembly 200 slides to a predetermined position along the connector 110, the bottom of the auxiliary insertion assembly 200 abuts against the auxiliary pulling-out assembly 300, drives the auxiliary pulling-out assembly 300 to move axially and accumulates elastic restoring force;

[0039] The fixing assembly 400 rotates with the movement of the auxiliary pulling-out assembly 300, and when the auxiliary pulling-out assembly 300 moves to a set stroke, the fixing assembly 400 is clamped into the groove 1001 to limit the further displacement of the auxiliary pulling-out assembly 300;

[0040] Considering that there are many brands of sockets on the market, different brands of sockets have differences in structural design, and due to the structural characteristics of some socket products, users need to exert a large external force to insert the power adapter plug into the socket, so as to realize effective insertion of the power adapter and the socket to establish a power supply connection, and in modern life, the use of power strips is common, when the power strip is used to supply power to electronic equipment, the user needs to first stably operate the power strip with his hand to avoid displacement of the power strip due to external force, and then accurately and stably inserts the power adapter plug into the power strip socket, so as to ensure that a reliable electrical connection is formed between the power adapter and the power strip. When the user uses the power adapter in different scenarios, he needs to spend extra effort and strength to deal with the differences in sockets and the fixing of power strips, therefore, the auxiliary insertion assembly 200 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 frictional force between the auxiliary insertion assembly 200, the connector 110 and the surface of the socket, which means that the user does not need to use a large force to easily insert the connector 110 into the socket, which significantly reduces the difficulty of insertion, especially for people with less strength such as children and the elderly. When the connector 110 is inserted into the socket, the auxiliary insertion assembly 200 slides downward and contacts the auxiliary pulling-out assembly 300, which drives the auxiliary pulling-out assembly 300 to slide downward to generate elastic force, and at the same time drives the fixing assembly 400 to rotate and be clamped in the groove 1001, thereby fixing the auxiliary pulling-out assembly 300 so that it cannot slide upward, and the elastic force in the auxiliary pulling-out assembly 300 is blocked during the contact between the connector 110 and the socket.

[0041] At the same time, considering that in actual use, it also needs a large force to pull the connector 110 out of the socket, which is inconvenient for the user, therefore, during the whole period of the connection of the connector 110 and the socket, the elastic force generated by the auxiliary pulling-out assembly 300 is in a suppressed state, once the user has the demand to pull out the connector 110, only needs to release the locking between the fixed assembly 400 and the groove 1001, and at the same time, applies an initial external force to the outside, after this operation, the originally blocked elastic force of the auxiliary pulling-out assembly 300 can be released immediately, this released elastic force and the outward pulling force applied by the user combine to form a strong combined force, by means of this combined force, even if it is a socket with great plugging and unplugging resistance, the connector 110 can also be easily pulled out of the socket, making the pulling-out process smooth and labor-saving, completely changing the previous situation of laborious pulling-out of the plug.

[0042] On the basis of the above, the specific structure is disclosed in detail:

[0043] In order to make the auxiliary insertion assembly 200 contact the surface of the socket when the connector 110 is inserted, and be in sliding connection with the surface of the connector 110 during this process, the parts of the auxiliary insertion assembly 200 need to be further disclosed, therefore, the auxiliary insertion assembly 200 comprises a connecting plate 210 sliding on the surface of the connector 110, the bottom of the connecting plate 210 is fixedly connected with a limiting sliding rod 2101, and the surface of the limiting sliding rod 2101 slides on the inner wall of the electronic adapter body 100;

[0044] The contact surface of the connecting plate 210 and the socket is made of rubber material;

[0045] When the user holds the electronic adapter body 100 and aligns the connector 110 with the socket to prepare for insertion, the connecting plate 210 first contacts the socket. Since the contact surface of the connecting plate 210 and the socket is made of rubber material, this material has a certain softness and friction, which can provide good cushioning and grip in the moment of contacting the socket, preventing the electronic adapter from slipping or deviating during insertion. With further insertion, the socket exerts an upward force on the connecting plate 210, causing the connecting plate 210 to drive the limiting sliding rod 2101 fixedly connected to the bottom thereof to slide downward along the inner wall of the electronic adapter body 100, thereby causing the connecting plate 210 to slide on the surface of the connector 110.

[0046] In order to make the structure of the roller 2201 of the auxiliary insertion assembly 200 make the sliding of the limiting sliding rod 2101 more easy, the other parts of the auxiliary insertion assembly 200 need to be disclosed, therefore, the inner wall of the inner cavity of the electronic adapter body 100 is fixedly connected with a sliding rail 230, and the inner wall of the sliding rail 230 is provided with a sliding groove 2301;

[0047] The limiting sliding rod 2101 is fixedly connected with a connecting column 220 at one end away from the connecting plate 210, and the connecting column 220 is fixedly connected with a roller 2201 at the bottom;

[0048] The roller 2201 slides on the inner wall of the sliding groove 2301; when the connecting plate 210 is in contact with the surface of the socket, the socket will exert an upward force on the connecting plate 210 at this time, so that the connecting plate 210 drives the limiting sliding rod 2101 fixedly connected thereto to move, so that the connecting column 220 at the other end of the limiting sliding rod 2101 and the roller 2201 slide in the sliding groove 2301 formed in the slide rail 230 fixedly arranged on the inner wall of the inner cavity of the electronic adapter body 100, and the roller 2201 rolls in the sliding groove 2301, thereby converting the sliding friction that may be generated between the limiting sliding rod 2101 and the slide rail 230 into rolling friction, greatly reducing the resistance when the auxiliary insertion assembly 200 slides downward, so that the auxiliary insertion assembly 200 can more smoothly slide downward along the surface of the connector 110, and the user only needs to exert a smaller force to push the connector 110 into the socket, thereby easily realizing the insertion function.

[0049] Considering that the auxiliary insertion assembly 200 will gradually abut against the auxiliary extraction assembly 300 when moving downward, the roller 2201 is fixedly connected with a connecting rod 240 at one end away from the connecting column 220, and the auxiliary extraction assembly 300 is located below the connecting rod 240; by sliding the roller 2201 in the sliding groove 2301, the connecting rod 240 is driven to move vertically downward and gradually abut against the auxiliary extraction assembly 300.

[0050] Considering that the auxiliary extraction assembly 300 will move downward in cooperation with the connecting rod 240 when the connecting rod 240 moves vertically downward, the parts of the auxiliary extraction assembly 300 need to be further disclosed, so the auxiliary extraction assembly 300 comprises a support frame 310 fixedly connected in the inner cavity of the electronic adapter body 100, a rotating column 320 rotatably connected to the inner wall of the support frame 310, a sliding column 330 slidably connected to the inner wall of the rotating column 320, and a damper 3301 fixedly connected in the inner cavity of the sliding column 330;

[0051] The top of the damper 3301 is in contact with 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;

[0052] First, when the connecting rod 240 moves downward, it will be inserted into the inner cavity of the sliding column 330 and in contact with the top of the damper 3301, and the continuous downward movement of the connecting rod 240 will cause the damper 3301 to contract, and when the damper 3301 cannot contract, it will drive the sliding column 330 to slide downward on the inner wall of the rotating column 320, and 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.

[0053] In order to make the slide column 330 rotate the column 320 can rotate in the inner wall of the support frame 310 when moving downward, thus, the damper 3301 surface is fixedly connected with the limiting rod 3302;

[0054] The surface of the rotating column 320 is provided with an annular groove 3201, which is arranged around the outer surface of the rotating column 320 and extends from the top to the bottom of the rotating column 320;

[0055] The surface of the limiting rod 3302 slides in the inner wall of the annular groove 3201; when the auxiliary pulling-out assembly 300 is operated, when the connecting rod 240 is driven to move downward by the auxiliary inserting assembly 200, it contacts the top of the damper 3301 and continuously presses downward, the damper 3301 is contracted, and drives the limiting rod 3302 connected thereto, because the limiting rod 3302 is slidably connected to the surface of the rotating column 320 in the annular groove 3201, during the contraction of the damper 3301, the limiting rod 3302 can only move in the annular groove 3201 according to the track of the groove.

[0056] In order to make the rotating column 320 rotate, it can drive the fixed assembly 400 to rotate, thus, the surface of the support frame 310 is provided with a through groove, the rotating column 320 rotates in the inner wall of the through groove, and the bottom of the rotating column 320 is connected with the end of the fixed assembly 400; the rotation of the rotating column 320 can drive the fixed assembly 400 to rotate synchronously.

[0057] In order to make the fixed assembly 400 rotate with the rotating column 320, the parts of the fixed assembly 400 need to be further disclosed, thus, the fixed assembly 400 comprises a rotating rod 410 fixedly connected to the bottom of the rotating column 320, and a cross rod 420 fixedly connected to the end away from the rotating column 320 of the rotating rod 410; 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 rod 420 to rotate synchronously.

[0058] In order to make the fixed assembly 400 can be clamped with the groove 1001, thus, the inner wall of the groove 1001 is fixedly connected with a fixed frame 430, and an arc-shaped groove is formed in the surface of the fixed frame 430, which is adapted to be connected with the surface of the cross rod 420; during the rotation of the rotating column 320, the rotating rod 410 connected thereto can be driven to rotate, and in turn the cross rod 420 is driven to rotate, when the cross rod 420 rotates, its outer surface will gradually approach the fixed frame 430 of the inner wall of the groove 1001, until the cross rod 420 is tightly matched with the arc-shaped groove in the surface of the fixed frame 430, the clamping action is completed, and the stable clamping of the fixed assembly 400 and the groove 1001 is realized, thereby preventing the rotating column 320 from rotating in the opposite direction, and making the damper 3301 move upward against the connecting rod 240.

[0059] To sum up, the workflow of the application:

[0060] As Figures 2-3 For the state distribution when the joint 110 is not inserted into the socket, the auxiliary insertion assembly 200 and the auxiliary pulling-out assembly 300 are not working;

[0061] As Figures 4-7 For the working state when the joint 110 is inserted into the socket, the auxiliary insertion assembly 200 slides on the surface of the joint 110, and the auxiliary pulling-out assembly 300 moves downward to drive the clamping of the fixing assembly 400;

[0062] Firstly, the handheld electronic adapter body 100 approaches the joint 110 to the socket. When the user holds the electronic adapter body 100 and aligns the joint 110 to the socket for insertion, the connecting plate 210 first contacts the socket. When the connecting plate 210 contacts the surface of the socket, the socket will exert an upward force on the connecting plate 210, causing the connecting plate 210 to move the limiting slide rod 2101 fixedly connected thereto, so that the connecting column 220 and the roller 2201 at the other end of the limiting slide rod 2101 will slide in the sliding groove 2301 formed in the slide rail 230 fixedly arranged in the inner wall of the electronic adapter body 100. The roller 2201 rolls in the sliding groove 2301, converting the sliding friction between the limiting slide rod 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 the bottom thereof 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 downward, the damper 3301 contracts, driving the limiting rod 3302 connected thereto. Since the limiting rod 3302 is slidingly 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 in the annular groove 3201 according to the track of the groove. 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 horizontal rod 420. When the horizontal rod 420 rotates, its outer surface will gradually approach the fixed frame 430 on the inner wall of the recess 1001, until the horizontal rod 420 is tightly fitted with the arc-shaped groove on the surface of the fixed frame 430, completing the clamping action, thereby realizing the stable clamping of the fixing assembly 400 and the recess 1001.
