Description

Technical Field

[0001] The utility model relates to the field of charging, in particular to an automatic plug ejecting device. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and new vehicle-mounted power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. Among them, vehicles that use charging methods generally need to be charged by charging guns to charge new energy electric vehicles. Of course, other products or equipment that need to be charged can also be charged by charging guns.

[0003] In the prior art, in order to realize that the plug is automatically ejected from the socket, see Figure 1 , 2 As shown, a plug push rod 102 is provided on the plug 101, a boss 103 is provided on the outer surface of the plug 101, a spring 105, a cover plate 106 and a push rod 107 are provided on the socket 104, and a hook 108 is provided on the cover plate 106. When the plug and the socket are plugged in, the plug push rod is inserted into the socket to compress the spring, and then the hook on the cover plate will hook the boss, so that the plug is limited in the socket. Among them, a coil 109 is also provided in the socket 104 outside the push rod 107. The push rod is located above the cover plate away from one end of the hook (the cover plate is connected to the socket through the shaft, and the socket is located between the push rod and the hook). When the plug needs to be automatically ejected, the coil is energized, and the magnetic field generated by the coil causes the push rod to be magnetized in the magnetic field to generate magnetic force and move downward, so that the bottom of the push rod is against the cover plate at one end of the shaft, which will push the cover plate to rotate around the shaft, so that the hook moves upward and disengages from the boss, so that the limiting force of the hook on the plug disappears, and the restoring force of the spring will push the plug out of the socket, thereby realizing the automatic ejection of the plug. However, this structure has the following shortcomings;

[0004] 1. It uses the method of pre-compression of the spring to store energy. If the spring is in a compressed state for a long time, the stored potential energy will be weakened (or the spring is compressed for a long time, and its recovery ability is impaired), so that the plug cannot be ejected normally, affecting the user experience;

[0005] 2. When the plug and the socket are plugged in, not only the tight-fitting plugging force of the plug and the socket needs to be overcome, but also the elastic force of the spring needs to be overcome to compress the spring. The user needs a certain amount of force to plug the plug and the socket, which is a bad user experience;

[0006] 3. The cover plate needs to be subjected to the outward thrust of the plug given by the spring for a long time (the boss gives the hook an outward thrust), the cover plate is easily damaged, or the rotating connection between the cover plate and the socket is easily deformed, and the maintenance rate is high. Summary of the invention

[0007] The utility model aims to provide an automatic plug ejection device, which can ensure the normal ejection of the plug and the stability of the plug being detached from the socket, reduce the maintenance rate, extend the service life, and improve the user experience.

[0008] To achieve the above object, the technical solution adopted by the utility model is: a plug automatic ejection device, comprising a plug and a socket, the socket is provided with a socket, the plug end of the plug is detachably plugged with the socket of the socket, a coil is installed in the socket, an iron core is installed in the plug end of the plug, and the iron core is arranged opposite to the coil;

[0009] When the plug end is inserted into the socket, the iron core is inserted into the coil;

[0010] When the coil is energized, the coil pushes the iron core and the plug out of the socket.

[0011] In the above technical solution, a plug push rod is provided in the middle of the plug end, a mounting cavity is provided inside the plug push rod, and the iron core is installed in the mounting cavity;

[0012] When the plug end is inserted into the socket, the plug push rod is inserted into the coil.

[0013] In the above technical solution, a wiring cavity is provided in the plug, and the rear end of the installation cavity is connected to the wiring cavity;

[0014] A plug pressing plate is installed in the wiring cavity, the rear end of the iron core is connected to the plug pressing plate, and the plug pressing plate limits the axial direction of the iron core in the installation cavity.

[0015] In the above technical solution, a socket pressing plate is installed in the socket, a coil frame is provided at the end of the socket pressing plate, the coil frame is inserted into the socket, and the coil is installed on the coil frame.

[0016] In the above technical solution, a cover plate is rotatably mounted on the outside of the socket, and the cover plate is rotatably connected to the socket via a rotating shaft, and the cover plate can open or close the socket.

[0017] In the above technical solution, a torsion spring is installed on the rotating shaft, and the torsion spring provides a rotational force to the cover plate, so that the cover plate closes the socket or places the cover plate close to the socket.

[0018] In the above technical solution, when the plug end is plugged into the socket, the end of the cover plate away from the shaft is arranged outside the plug, and the torsion spring pushes the end of the cover plate to contact the outer surface of the plug.

[0019] In the above technical solution, when the plug is away from the socket, the torsion spring pushes the cover plate to rotate, and causes the cover plate to close the socket.

[0020] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0021] 1. In the utility model, the iron core is directly installed in the plug-in end of the plug, and the coil is installed in the socket of the socket. When the plug and the socket are plugged in, the plug-in connection between the two is directly realized, and the plug-in force between the plug and the socket is used to prevent the two from being separated. When the plug needs to be ejected, the coil is directly energized to push the iron core inside the coil outward through the magnetic field generated by the coil. When the iron core is pushed outward, it drives the plug to move synchronously to realize the automatic ejection of the plug. Compared with the previous method of using a spring, the automatic ejection of the plug is more stable, the maintenance rate is also low, the service life is extended, and the user experience is improved;

[0022] 2. The cover plate of the utility model does not need to provide a limiting force to the plug, which can prevent the cover plate from being deformed and damaged, reduce the maintenance rate, and extend the service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1: See Figure 3 , 4 As shown, a plug automatic ejection device comprises a plug 1 and a socket 2, wherein the socket 2 is provided with a socket 3, the plug end 4 of the plug 1 is detachably plugged with the socket 3 of the socket 2, a coil 5 is installed in the socket 3, and an iron core 6 is installed in the plug end 4 of the plug 1, and the iron core 6 is arranged opposite to the coil 5;

[0030] When the plug end 4 of the plug 1 is inserted into the socket 3, the iron core 6 is inserted into the coil 5;

[0031] When the coil 5 is energized, the coil 5 pushes the iron core 6 and the plug 1 to detach from the socket 3 of the socket 2 .

[0032] In this embodiment, the plug has a plug terminal (not shown in the figure), and the socket has a socket terminal (not shown in the figure). When the plug and the socket are plugged together, the plug terminal and the socket terminal are plugged together to achieve electrical connectivity between the plug and the socket. At the same time, when the plug end of the plug is inserted into the socket, the iron core is inserted into the coil, and the coil is connected to the power supply or power supply mechanism. The coil is powered by the power supply or power supply mechanism. When the plug and the socket are plugged together and the plug does not need to be removed from the socket, the coil is temporarily de-energized. When the plug ejection signal is received, the power supply or power supply mechanism energizes the coil (in this embodiment, direct current is supplied to the coil). After the coil is energized, a magnetic field is generated inside it. The magnetic force generated by the magnetization of the iron core in the magnetic field pushes it to move outward. Since the iron core and the plug-in end of the plug are connected, the two cannot move relative to each other. Therefore, under the thrust of the outward movement of the iron core, the plug is driven to move synchronously in the direction away from the socket, thereby realizing the separation of the plug and the socket, that is, the automatic ejection of the plug. When the iron core is separated from the coil, the power supply to the coil is stopped, so that the coil will not be in the energized state all the time, and will not affect the subsequent plugging of the plug and the socket.

[0033] At the same time, in the utility model, the stability of the plug ejection can be ensured only by providing a stable current to the coil, and there will be no problem with the spring.

[0034] See also Figure 3 , 4 As shown, a plug push rod 7 is provided in the middle of the plug end 4, a mounting cavity 8 is provided inside the plug push rod 7, and the iron core 6 is installed in the mounting cavity 8;

[0035] When the plug end 4 of the plug 1 is inserted into the socket 3 , the plug push rod 7 is inserted into the coil 5 .

[0036] In this embodiment, the plug top rod, the plug and the plug-in end are all made of insulating materials, and the iron core is installed in the plug top rod. This prevents the iron core from being exposed and conducting electricity, thereby reducing safety hazards. At the same time, the iron core is not exposed and is not directly exposed to the air to prevent rust, thereby ensuring that it is inserted into the coil. The magnetic field generated by the coil can smoothly and stably push the iron core out of the coil, thereby ensuring service life and safety of use, and reducing maintenance rate.

[0037] See also Figure 3 , 4 As shown, a wiring cavity 9 is provided in the plug 1, and the rear end of the mounting cavity 8 is connected to the wiring cavity 9;

[0038] A plug pressing plate 10 is installed in the wiring cavity 9 , and the rear end of the iron core 6 is connected to the plug pressing plate 10 . The plug pressing plate 10 limits the axial position of the iron core 6 in the installation cavity 8 .

[0039] Among them, the installation cavity and the wiring cavity are connected, so when the iron core is assembled, it is directly inserted from the wiring cavity into the installation cavity, and then the iron core is limited by the plug pressure plate, which improves the convenience of installing and disassembling the iron core. At the same time, the plug pressure plate can also limit the plug terminal installed in the plug-in end, playing a dual role.

[0040] See also Figure 3 , 4 As shown, a socket pressing plate 11 is installed in the socket 2 , a coil frame 12 is provided at the end of the socket pressing plate 11 , the coil frame 12 is inserted into the socket 3 , and the coil 5 is installed on the coil frame 12 .

[0041] The socket pressure plate can limit the socket terminal (not shown in the figure) installed in the socket, and the coil skeleton is set to install and position the coil. The coil skeleton is a ring structure made of insulating material. The coil will be installed on the inner wall of the coil skeleton. The coil skeleton, coil, plug top rod and iron core are coaxially arranged. In this way, when the coil is on the coil skeleton, the limit will not be exposed, that is, it will be isolated from the socket terminal through the coil skeleton to prevent electrical connection, or the socket terminal affects the electrical performance of the coil, which is safer and more stable to use.

[0042] See also Figure 3 , 4As shown, a cover plate 13 is rotatably mounted on the outside of the socket 2, and the cover plate 13 is rotatably connected to the socket 2 via a rotating shaft 14. The cover plate 13 can open or close the socket 3. When the plug is not plugged into the socket, the cover plate closes the socket of the socket to protect it. When the plug needs to be plugged into the socket, the cover plate is opened to expose the socket, and then the plug is inserted into the socket of the socket.

[0043] In this embodiment, there is no need to set a spring in the socket, so that when the plug and the socket are plugged in, the plug will not be pushed away from the socket by the elastic force of the spring, and there is no need to hook the plug with the hook of the cover plate, that is, there is no need to set a boss and cover plate on the plug to cooperate, so the structure of the plug can be simpler. At the same time, the cover plate does not need to be subjected to the pulling force of the plug, so the cover plate is not easy to deform, has a longer service life, and a lower maintenance rate.

[0044] Wherein, a torsion spring is installed on the rotating shaft, and the torsion spring provides a rotational force to the cover plate, so that the cover plate closes the socket or places the cover plate close to the socket.

[0045] When the plug end is plugged into the socket, the end of the cover plate away from the rotating shaft is arranged outside the plug, and the torsion spring pushes the end of the cover plate to contact the outer surface of the plug. In this way, the cover plate is only subjected to the restoring force of the torsion spring, so that the end of the cover plate is against the outer surface of the plug, and is no longer subjected to the thrust of the spring in the previous structure. In this way, the rotating shaft only needs to bear the force of the cover plate itself, the rotating shaft is not easy to deform or damage, and the cover plate is not easy to deform or damage. The requirements for the cover plate can be lower, so the production cost of the cover plate can also be lower.

[0046] When the plug is away from the socket, the torsion spring pushes the cover plate to rotate and close the socket. In this way, the operator does not need to manually drive the cover plate to close the socket (because the user may forget this step in actual use), which can effectively ensure the protective effect of the cover plate on the socket and improve the user experience.

[0047] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0048] In the present utility model, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, or an integral one; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, for example, the two can form a mechanical abutment or abutment connection through abutment, contact, etc., the two can also be directly hung or hung through an intermediate medium, etc., or it can be the internal connection of the two elements or the interaction relationship between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
