Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automobile charging piles, and more specifically, to an automobile charging pile socket. Background Art
[0002] With the progress of society and the continuous improvement of people's living standards, the number of cars has increased year by year, and there are more and more families owning multiple cars. The resulting environmental pollution has become more serious. In order to solve the problem of environmental pollution, electric vehicles came into being. With the development of time, electric vehicles have become more and more popular, and naturally there are more and more charging piles for charging electric vehicles.
[0003] At present, most charging sockets for gun-free charging piles are equipped with outer covers to protect the sockets from water and dust. However, there is still a gap between the outer cover of the existing charging socket and the shell around the charging socket, or when the outer cover is forgotten to be closed or is not closed tightly, foreign objects such as rain or dust may still enter the charging socket, which may easily cause faults such as poor terminal contact. On the other hand, during use, when the outer cover is opened to prepare for charging, or after charging is completed and the gun is pulled out, all sockets are exposed, especially the N, L1, L2, and L3 sockets, and there is a risk of electric shock caused by accidental touch of fingers. Summary of the invention
[0004] In order to solve the above problems, the present application provides a car charging pile socket.
[0005] The present application provides a car charging pile socket adopting the following technical solution:
[0006] A car charging pile socket comprises a main seat body, in which a plurality of plug-in terminals are embedded and fixedly connected, the top of the main seat body is detachably fixedly connected to an upper cover and an end cover in sequence by screws, the centers of the upper cover and the end cover are provided with through holes for inserting a charging gun corresponding to the plug-in terminals, one side of the top of the end cover is rotatably connected to an outer flip cover, a cavity is provided between the main seat body and the upper cover, a baffle mechanism is movably connected in the cavity, and is used to shield the N, L1, L2 and L3 sockets in the plug-in terminals, and the bottom of the main seat body is detachably fixedly connected to a rear cover by screws.
[0007] Furthermore, the baffle mechanism includes a push block and a baffle plate. The push block is slidably connected to the top side of the main seat body. A return spring is also arranged between the back side of the push block and the side wall of the main seat body. There are two baffle plates, which are symmetrically arranged on both sides of the push block and are rotatably connected to the main seat body.
[0008] Furthermore, ear plates are fixedly connected to both sides of the push block, and the tops of the ends of the ear plates are fixedly connected to limiting columns.
[0009] Furthermore, the blocking piece is kidney-shaped, the upper end of which is rotatably connected to the main seat body, and a waist-shaped hole is provided in the middle section, and the two waist-shaped holes are respectively sleeved on the two limiting columns.
[0010] Through the above technical solution, when the charging gun is inserted into the socket, the gun head of the charging gun touches the push block to apply thrust, and the push block slides inward and contracts, and then drives the left and right baffles to rotate outward and separate through the ear plates and limit columns on both sides, revealing the plug-in terminals they are blocking, so that the charging gun can be smoothly inserted; when the charging gun is pulled out, the push block loses thrust, the spring rebounds, and the push block resets, thereby driving the left and right baffles to rotate inward, thereby blocking the plug-in terminals.
[0011] Furthermore, a limiting notch is provided on the side of the limiting column, and a corresponding limiting protrusion is provided on the inner wall of the waist-shaped hole.
[0012] Through the above technical solution, when the left and right baffles are in a state of inward contraction, the limiting notch and the limiting protrusion are engaged to complete self-locking. At this time, the limit can only be released by moving the push block upward, which can effectively prevent the baffle from rotating and separating due to actions other than inserting the charging gun, thereby effectively improving the structural stability.
[0013] Furthermore, a slope is arranged on the top of the front side of the push block.
[0014] The above technical solution makes it easier to insert the charging gun.
[0015] In summary, the present application includes at least one of the following beneficial technical effects:
[0016] (1) The present application adds a baffle mechanism inside the traditional outer cover, which can automatically separate and merge during the insertion and removal of the charging gun, thereby automatically shielding the N, L1, L2 and L3 sockets in the plug-in terminal, effectively preventing foreign objects such as rainwater or dust from entering the socket due to the outer cover not being closed tightly, causing poor terminal contact and other faults, and also effectively avoiding the risk of electric shock caused by accidental touch of fingers;
[0017] (2) Through the cooperation between the push block and the spring and the main seat body, the charging gun at the power supply end is also fixed, which can improve the stability of the charging gun when it is inserted;
[0018] (3) By setting the limiting notch and the limiting protrusion, when the push block is not moving, the left and right baffles are always in a self-locking state, which effectively avoids the phenomenon of the baffles rotating and separating due to the non-charging gun insertion action, and improves the structural stability and safety.

[0030] Embodiment 1:
[0031] The following is combined with Figure 1-6 This application is described in further detail.
[0032] The embodiment of the present application discloses a car charging pile socket, including a main seat body 1, in which a plurality of plug-in terminals 2 are embedded and fixedly connected, the top of the main seat body 1 is detachably fixedly connected to an upper cover 3 and an end cover 4 in sequence by screws, the center of the upper cover 3 and the end cover 4 is penetrated by a through hole for inserting a charging gun corresponding to the plug-in terminal 2, and an outer flip cover 5 is rotatably connected to one side of the top of the end cover 4, a cavity is provided between the main seat body 1 and the upper cover 3, and a baffle mechanism 6 is movably connected in the cavity for shielding the N, L1, L2 and L3 sockets in the plug-in terminal 2, and the bottom of the main seat body 1 is detachably fixedly connected to a rear cover 7 by screws.
[0033] See also Figure 1 and Figure 2 The baffle mechanism 6 includes a push block 61 and a baffle 62. The push block 61 is slidably connected to one side of the top of the main seat body 1. A return spring 63 is also arranged between the back side of the push block 61 and the side wall of the main seat body 1. There are two baffles 62, which are symmetrically arranged on both sides of the push block 61 and are both rotatably connected to the main seat body 1.
[0034] See also Figure 2 and Figure 4 The two sides of the push block 61 are fixedly connected with ear plates 611 , and the tops of the ends of the ear plates 611 are fixedly connected with limiting pillars 612 .
[0035] See also Figure 2 , Figure 3 and Figure 6 The blocking piece 62 is kidney-shaped, and its upper end is rotatably connected to the main seat body 1. A waist-shaped hole 621 is provided in the middle section, and the two waist-shaped holes 621 are respectively sleeved on the two limiting columns 612.
[0036] When the charging gun is inserted into the socket, the tip of the charging gun touches the push block 61 to apply a thrust, and the push block 61 slides inward and contracts, and then drives the left and right baffles to rotate outward and separate through the ear plates 611 and the limit columns 612 on both sides, exposing the plug-in terminal 2 that is blocked, so that the charging gun can be smoothly inserted; when the charging gun is pulled out, the push block 61 loses the thrust, the spring rebounds, and the push block 61 resets, thereby driving the left and right baffles to rotate inward, thereby blocking the plug-in terminal 2.
[0037] See also Figure 3 and Figure 5Preferably, a limiting notch 613 is provided on the side of the limiting column 612, and a corresponding limiting protrusion 622 is provided on the inner wall of the waist-shaped hole 621. When the left and right baffles are in a state of inward contraction, the limiting notch 613 and the limiting protrusion 622 are engaged with each other to complete self-locking. At this time, the limit can only be released when the push block 61 is moved upward, which can effectively prevent the baffle from rotating and separating due to actions other than inserting the charging gun, and effectively improve the structural stability.
[0038] See also Figure 1 and Figure 2 As a further preferred embodiment of this embodiment, a slope is provided on the top of the front side of the push block 61, which can make it easier to insert the charging gun.
[0039] The implementation principle of a car charging pile socket in the embodiment of the present application is:
[0040] The present application can shield the N, L1, L2 and L3 sockets in the plug-in terminal 2 by setting the baffle mechanism 6. When the charging gun at the power supply end is inserted into the socket, the head of the charging gun first touches the push block 61 to apply a thrust, and the push block 61 shrinks and slides inward in its fixed track, and then drives the baffles on the left and right sides to rotate outward and separate through the ear plates 611 and the limit columns 612 on both sides, exposing the blocked plug-in terminal 2, so that the charging gun can be smoothly inserted; when the charging gun is pulled out, the push block 61 loses its thrust, the spring rebounds, and the push block 61 resets, thereby driving the left and right baffles to rotate inward, thereby shielding the plug-in terminal 2.
[0041] Furthermore, the push block 61 cooperates with the main seat body 1 through a spring, and moves back and forth on its sliding track by applying force to the spring, while also fixing the charging gun at the power supply end.
[0042] Furthermore, through the setting of the limiting notch 613 and the limiting protrusion 622, when the push block 61 is not moving, the left and right blocking pieces 62 are always in a self-locking state. At this time, when the left and right blocking pieces 62 are directly touched, they will not be separated, and the N, L1, L2, and L3 jacks will be blocked. Only when the charging gun is inserted and drives the push block 61 to move, the left and right blocking pieces 62 will be unlocked and opened, exposing the N, L1, L2, and L3 jacks, effectively avoiding the rotation and separation of the blocking pieces 62 caused by non-charging gun insertion actions, thereby improving the structural stability and safety.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
