Description

Technical Field

[0001] The present invention relates to the technical field of power plugs, and in particular to a power plug and a power socket based on protocol identification. Background Art

[0002] The power plug is a device that connects electrical appliances and other devices to the power supply. The appearance, grade, size and type of power sockets and plugs vary according to the country and region. Each country has its own government-made standards for use in various fields. Depending on the purpose of the power plug, the power cord plug can be used at 250V, 125V, and 36V voltages, and can be used at 16A, 13A, 10A, 5A, and 2.5A according to the current. The frequency is generally 50 / 60Hz.

[0003] Under current usage conditions, power plugs can be divided into fast charging and slow charging, which differ in charging speed, principle, quality, price and battery life.

[0004] Existing power sockets can only be executed according to the set current and voltage standards, that is, any power socket can only realize one of fast charging or slow charging, resulting in a relatively single application object. Different application objects need to be equipped with different power sockets. When a user holds multiple application objects, it is difficult to accurately find the corresponding power socket, resulting in the problem of inability to achieve efficient charging; at the same time, if the power is lost while being used at the same time during the charging process, the ordinary slow charging socket cannot charge the battery while maintaining normal use, resulting in the problem of low charging efficiency. Therefore, the present invention proposes a power plug and a power socket based on protocol identification. Summary of the invention

[0005] The invention content of the present invention is to provide a power plug and a power socket based on protocol identification, which mainly solves the problem that the existing power socket can only realize one of fast charging or slow charging, resulting in different application objects needing to be equipped with different power sockets, resulting in users holding multiple application objects It is difficult to accurately find the corresponding power socket, resulting in the problem that efficient charging cannot be achieved; at the same time, if the charging process is used simultaneously, the slow charging power socket can no longer charge the battery under the premise of maintaining normal use, resulting in low charging efficiency.

[0006] The present invention proposes a power plug based on protocol identification, comprising:

[0007] A power detection terminal, arranged at one end of the power plug;

[0008] A protocol detection terminal is arranged on the same side of the power plug as the power detection terminal, and the protocol detection terminal is arranged in parallel with the power detection terminal;

[0009] A connecting wire, arranged at the other end of the power plug;

[0010] When the power plug triggers the power detection end and the protocol detection end at the same time, the fast charging current is transmitted along the connecting line; when the power plug only triggers the power detection end, the slow charging current is transmitted along the connecting line.

[0011] Preferably, the protocol detection end is arranged at an edge of one end of the power detection end, and is concave from the outer edge of the power detection end to form a limiting groove connected to the protocol detection end.

[0012] Preferably, the horizontal plane where the free end surface of the power detection end is located is higher than the horizontal plane where the free end surface of the protocol detection end is located;

[0013] A detection hole is formed on the free end surface of the power detection end, and a detection channel is formed inwardly along the detection hole; the length direction of the detection channel is the same as the length direction of the power detection end and the protocol detection end.

[0014] Preferably, there are three detection holes and detection channels, which are distributed in a herringbone shape on the power detection end;

[0015] The protocol detection end is arranged on a long side of the power detection end distributed in a herringbone shape.

[0016] Preferably, the power detection end further includes:

[0017] The power detection terminal has the same number as the detection channels and is respectively arranged in each detection channel; one end of the power detection terminal is arranged to abut against the end surface of the power plug.

[0018] The present invention also proposes a power socket based on protocol identification, which is arranged in conjunction with the above-mentioned power plug, comprising:

[0019] A slot, the opening of which is arranged on the upper end surface of the power socket;

[0020] A power terminal is built into the slot, and the length direction of the power terminal is the same as the length direction of the slot;

[0021] A protocol terminal, which is protrudingly arranged on a side wall of the slot, and the length direction of the protocol terminal is the same as the length direction of the slot;

[0022] The power terminal detects whether it is connected to the power detection end in alignment. If so, it further determines whether the protocol terminal is connected to the protocol detection end in alignment. If so, a fast charging current is output at the power terminal. Otherwise, a slow charging current is output at the power terminal.

[0023] Preferably, the power terminal is protruding from the bottom of the slot, and extends outside the power socket to form a first connecting column;

[0024] The protocol terminal is protruded from the bottom of the slot along the side wall of the slot, and the protocol terminal extends outside the power socket to form a second connecting column.

[0025] Preferably, there are three power terminals, which are distributed in a herringbone shape;

[0026] There are at least two protocol terminals, which are parallelly distributed on the side walls opposite to the long sides of the power terminals distributed in a herringbone shape.

[0027] Preferably, the slot and the power detection end on the external power plug are arranged to avoid each other;

[0028] The protocol terminal includes a metal sheet with a protrusion and a metal groove recessed in the side wall of the slot; one end of the metal sheet is fixed to the end of the metal groove close to the slot opening, and the other end can move along the length direction of the metal groove and lower its own height during the movement.

[0029] Preferably, during the alignment and installation process of the slot and the external power plug, the metal sheet of the protocol terminal is aligned and connected with the auxiliary slot on the external power plug, and the metal sheet is pressed down along the process of the power plug and the slot until the power socket abuts the bottom end of the slot, and the metal sheet is connected to the protocol detection end.

[0030] As can be seen from the above, the application of the technical solution provided by the present invention can achieve the following beneficial effects:

[0031] First, the power plug and the power socket proposed in the present invention can determine whether the current mode is fast charging mode or slow charging mode according to the connection of the protocol detection terminal according to the preset protocol rules, and then output the appropriate current, so that a single device can achieve fast charging and slow charging. On the premise of meeting the charging and use needs of users, the number of power plugs and power sockets is reduced, providing convenience for users and achieving efficient charging;

[0032] Second, the power plug and the power socket proposed in the present invention use the power detection terminal as a preliminary positioning structure. After the positioning is completed, it can ensure that when there is a protocol output terminal, it can be connected to the protocol detection terminal in an aligned manner, ensuring that the device that allows the fast charging mode is charged in the fast charging mode, and ensuring the exact conversion between fast charging and slow charging on the power plug and the power socket;

[0033] Thirdly, the power plug and the power socket proposed in the present invention are connected in position through the downward pressure of the protocol terminal and the metal sheet, which ensures that fast charging can only be achieved when the power plug and the power socket are tightly connected. In an environment with high current or high heat, the safety of the power plug and the power socket is further guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Existing power sockets can only realize fast charging or slow charging, which means that different application objects need to be equipped with different power sockets. It is difficult for users to accurately find the corresponding power sockets when holding multiple application objects, resulting in the problem of inability to achieve efficient charging. At the same time, if the charging process is used at the same time, the slow charging power socket can no longer charge the battery under the premise of normal use, resulting in low charging efficiency.

[0040] Example 1

[0041] like Figure 1 and Figure 2As shown, in order to solve the above problems, this embodiment proposes a power plug 100 based on protocol identification, including a power detection terminal 110, a protocol detection terminal 120 and a connecting line 130; the power detection terminal 110 is arranged at one end of the power plug 100; the protocol detection terminal 120 and the power detection terminal 110 are arranged on the same side of the power plug 100, and the protocol detection terminal 120 and the power detection terminal 110 are arranged in parallel; the connecting line 130 is arranged on the other side of the power plug 100. When the power detection terminal 110 and the protocol detection terminal 120 are triggered at the same time, the power plug 100 transmits a fast charging current along the connecting line 130; when only the power detection terminal 110 is triggered, the power plug 100 transmits a slow charging current along the connecting line 130.

[0042] Preferably, in this embodiment, the middle section of the power plug 100 is a rectangular shell, and the power detection terminal 110 and the protocol detection terminal 120 are arranged on one end surface of the rectangular shell, and the power detection terminal 110 and the protocol detection terminal 120 are arranged parallel to each other.

[0043] Preferably, in this embodiment, the power detection terminal 110 is centrally disposed at one end of the power plug 100 .

[0044] Preferably, the safety current of the connecting line 130 in this embodiment is preferably a fast charging current, that is, the power plug 100 described in this embodiment can adapt to the passage of fast charging current for a long time, and the use of a slow charging current with a smaller amplitude will obviously have no effect on the connecting line 130.

[0045] In this embodiment, the power detection terminal 110 on the power plug 100 is used to connect to the power terminal on the socket, and the protocol detection terminal 120 is used to connect to the protocol terminal on the socket. If a protocol terminal is provided on the socket, the protocol on the current plug can be activated, and the fast charging current can be achieved through protocol control, thereby enabling the power plug 100 to achieve the effect of a fast charging head; if the corresponding socket does not have a protocol terminal, only the activation of the power terminal can achieve the effect of a normal slow charging current.

[0046] More specifically, the protocol detection terminal 120 is disposed at an edge of one end of the power detection terminal 110 , and a limiting groove 140 connected to the protocol detection terminal 120 is formed by being recessed from the outer edge of the power detection terminal 110 .

[0047] Preferably, the power detection end 110 is a rectangular columnar structure with long and short sides formed thereon, and the protocol detection end 120 is disposed on the long side of the power detection end 110 .

[0048] Preferably, in this embodiment, the area of ​​the power detection terminal 110 is larger than the area of ​​the protocol detection terminal 120 .

[0049] In this embodiment, when the power detection end 110 is aligned with the power terminal of the socket, the rough positioning of the plug and the socket is achieved. As the power detection end 110 and the power terminal are assembled together, if a protocol terminal is provided on the socket, it will be connected to the protocol detection end 120. Since the protocol detection end 120 is usually small, positioning through the power detection end 110 in the manner described in this embodiment can greatly improve the accuracy of protocol detection between the plug and the socket.

[0050] More specifically, the horizontal plane where the free end surface of the power detection terminal 110 is located is higher than the horizontal plane where the free end surface of the protocol detection terminal 120 is located; the free end surface of the power detection terminal 110 is formed with a detection hole 111, and a detection channel is formed inwardly along the detection hole 111; the length direction of the detection channel is the same as the length direction of the power detection terminal 110 and the protocol detection terminal 120.

[0051] Preferably, in this embodiment, there are three detection holes 111 and detection channels, which are distributed in a herringbone shape on the power detection end 110. Correspondingly, the protocol detection end 120 is arranged on a long side of the herringbone-shaped power detection end 110.

[0052] Preferably, in this embodiment, a power detection terminal 110 is provided in each detection channel; one end of the power detection terminal 110 is provided against the end surface of the power plug 100. Preferably, but not limited to, in this embodiment, the power detection terminal 110 should extend into the inside of the power plug 100 and make corresponding electrical connections, but this embodiment does not involve the internal circuit structure, so it is only stated that it is provided against the end surface of the power plug 100. Preferably, but not limited to, in this embodiment, the free end of the power detection terminal 110 should be located below the open end surface of the detection channel to improve the connection safety between the plug and the socket.

[0053] Preferably, the three detection channels in this embodiment can be connected to the live power pin, the neutral power pin and the ground power pin respectively, and the existing power plug 100 arranges the three power pins in a herringbone shape, so the power detection terminal 110 of this embodiment is also arranged in position. If the layout of the power pins changes with the advancement of the times, the structure of the power detection terminal 110 in this embodiment will also change accordingly. It obviously does not require creative labor, but changes accordingly to achieve normal connection of electrical signals.

[0054] In this embodiment, the detection hole 111 on the power detection terminal 110 further realizes precise positioning with the socket, which can ensure the detection and connection between the protocol detection terminal 120 with a smaller contact area and the protocol terminal.

[0055] It should be emphasized that in this embodiment, the protocol detection end 120 includes at least two protocol detection terminals 121 (preferably CC PIN & NTC terminals), and all protocol detection terminals 121 have the same shape, and are preferably evenly spaced and distributed on the long side of the power detection end 110. Preferably, different protocol detection terminals 121 can realize the detection of different protocols. For example, when only one protocol detection terminal 121 is activated and when two or more protocol detection terminals 121 are activated, the current amplitude is different. For example, if the slow charging current is 2A, the current is 5A when a single protocol detection terminal 121 is activated, and the current is 10A when two or more protocol terminals are activated, and so on; or only when all protocol detection terminals 121 are activated, can the complete activation of the protocol detection end 120 be determined. For example, if the slow charging current is 2A, the current is directly adjusted to a fast charging current such as 10A when all protocol terminals are activated.

[0056] Example 2

[0057] like Figure 3 As shown, in order to solve the aforementioned problems, the present embodiment proposes a power socket 200 based on protocol identification, which is matched with the power plug 100 in Embodiment 1, and includes a slot 210, a power terminal 220 and a protocol terminal 230; the opening of the slot 210 is arranged on the upper end surface of the power socket 200; the power terminal 220 is built into the slot 210, and the length direction of the power terminal 220 is the same as the length direction of the slot 210; the protocol terminal 230 is protruded and arranged on the side wall of the slot 210, and the length direction of the protocol terminal 230 is the same as the length direction of the slot 210; the power terminal 220 detects whether it is aligned with the power detection terminal 110, and if so, it further determines whether the protocol terminal 230 is aligned with the protocol detection terminal 120, and if so, a fast charging current is output at the power terminal 220, otherwise, a slow charging current is output at the power terminal 220.

[0058] Preferably, the power socket 200 in this embodiment should have a main body structure, on which a plurality of parallel power sockets 200 can be arranged, and each power socket 200 has the same structure. Preferably but not limited to, the slot 210 on the power socket 200 in this embodiment should be arranged perpendicular to the open end surface.

[0059] In this embodiment, the slot 210 and the power detection terminal 110 are roughly positioned, and the power terminal 220 and the power detection terminal 110 are precisely positioned. At this time, the protocol terminal 230 set on this embodiment is in place. If there is a corresponding protocol detection terminal 120, the protocol will be started and a large current will be transmitted; if the protocol detection terminal 120 is not set on the plug matched with this embodiment, the electrical signal transmission is directly realized according to the connection of the power detection terminal 110, that is, the setting of the protocol terminal 230 in this embodiment will not affect the normal connection relationship between the plug and the socket.

[0060] More specifically, the power terminal 220 is protruded from the bottom of the slot 210, and extends outside the power socket 200 to form a first connecting column; the protocol terminal 230 is protruded from the bottom of the slot 210 along the side wall of the slot 210, and the protocol terminal 230 extends outside the power socket 200 to form a second connecting column.

[0061] Preferably, in this embodiment, the first connecting column adopts a hollow cylindrical structure; the second connecting column adopts a frame structure with three baffles.

[0062] Preferably, in this embodiment, there are three power terminals 220, which are distributed in a herringbone shape; there are three protocol terminals 230, which are distributed in parallel and evenly spaced on the side walls opposite to the long sides of the herringbone-shaped power terminals 220.

[0063] In this embodiment, the power terminal 220 extends out of the detection channel of the plug and is connected to the internal power detection terminal 110. At this time, the protocol terminal 230 is connected to the protocol detection terminal 120 to activate the protocol and output the fast charging current.

[0064] More specifically, the slot 210 and the power detection terminal 110 on the external power plug 100 are arranged to avoid each other; the protocol terminal 230 includes a protruding metal sheet and a metal groove recessed in the side wall of the slot 210; one end of the metal sheet is fixed to the end of the metal groove close to the opening of the slot 210, and the other end can move along the length direction of the metal groove and lower its own height during the movement.

[0065] In this embodiment, during the alignment and installation process of the slot 210 and the external power plug 100, the metal sheet of the protocol terminal 230 is aligned and connected with the auxiliary groove on the external power plug 100, and the metal sheet is pressed down along the combination process of the power plug 100 and the slot 210 until the power socket 200 abuts against the bottom end of the slot 210, and the metal sheet is connected to the protocol detection end 120.

[0066] To summarize, the present embodiments 1 and 2 propose a method of detecting a power socket and a power socket based on a protocol, by adding a protocol end on the basis of the power end, and detecting whether the protocol end is aligned to determine whether it can support and run the fast charging current. If so, the fast charging current is transmitted based on the protocol; if there is no protocol detection end or protocol terminal, it is considered that the fast charging current is not supported, and the slow charging current is transmitted. The current can be quickly converted through a power plug and a power socket, and the implementation principle is relatively simple, and the structure does not change much, and it can still be adapted to the current of conventional plugs or sockets at this stage.

[0067] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
