Description

Technical Field

[0001] The utility model relates to the technical field of charging pile protection, in particular to an automobile DC charging pile with a plug protection function. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in parking lots or charging stations in public buildings and residential areas. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. In order to increase the service life of the charging pile, a protective mechanism is usually set at the charging plug. Although the existing charging piles are equipped with a plug protection mechanism, the charging pile plug is still exposed to the outside of the charging pile, and it is easy to age if exposed to direct sunlight for a long time.

[0003] Not only will the plug of the charging pile age, but the charging gun of the charging pile may also fall off when it is not placed stably. The falling of the charging gun will seriously damage the charging gun, causing it to malfunction the next time it works, affecting personnel safety, reducing work efficiency, etc.

[0004] In the prior art, a Chinese patent with a publication number of CN217022237U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a DC charging pile for automobiles with a plug protection function, comprising a box body, a vertical plate is rotatably connected inside the box body, a shell is installed on the rear surface of the vertical plate, a cable is arranged inside the shell, one end of the cable passes through the inner side wall of the shell and the rear surface of the vertical plate and is installed with a plug, a placement groove is installed on the front surface of the vertical plate, an end of the plug away from the cable is inserted into the placement groove, a groove is opened on the outer side wall of the plug, a slider is inserted in the groove, a spring is arranged between one side of the slider and the inner wall of the groove, a cover plate is hinged on the top of the slider, a rotating rod is fixedly connected to the top of the vertical plate, and a sleeve is fixedly connected to the top of the box body, wherein the device solves the problem that the current charging pile plug is easily aged when exposed to the outside, but there is a risk of falling if the charging gun is placed unstably, which leads to the problem of malfunction of the charging gun. Summary of the invention

[0005] The purpose of the utility model is to provide a car DC charging pile with a plug protection function to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A car DC charging pile with a plug protection function comprises a charging pile body, charging guns are symmetrically arranged on the charging pile body, fixing parts for fixing the charging guns are symmetrically connected to the charging pile, a shell is arranged at the plug connection of the charging gun, the shell is fixedly connected to the charging gun, sliding grooves are symmetrically opened on the shell, the sliding grooves are arranged in a T shape, a bayonet is opened on the top of the shell, and a buckle part for clamping the charging gun is connected to the charging pile body.

[0008] When charging is completed, the charging gun will be placed at the socket on the main body of the charging pile. At this time, the charging gun is pushed into the socket. After being pushed to a certain distance, the fixing component starts working under pressure, limiting the charging gun, and then drives the buckle component located at the back to start working. In this process, the fixing component and the buckle component continue to work in conjunction. When the fixing component completely fixes the charging gun, it will also drive the buckle component to lock the charging gun, thereby achieving the purpose of linkage locking. When the charging gun needs to be taken out, turn on the switch, so that the buckle component and the fixing component are no longer locked at the same time, and the charging gun can be easily taken out.

[0009] A further improvement of the technical solution of the utility model is that the fixing component includes a box body, a telescopic hole is opened on the top of the box body, the box body is fixedly connected to the charging pile body, a card block is arranged inside the box body, the card block is complementary to the card slot opened on the shell, a support shaft is fixedly connected to the top of the card block, the support shaft is slidably connected to the charging pile body, a first spring is arranged between the card block and the charging pile body, one end of the first spring is fixedly connected to the card block, the other end of the first spring is fixedly connected to the charging pile body, and a support plate is fixedly connected to the end of the support shaft away from the card block.

[0010] The above technical solution is adopted. In this solution, when the charging gun enters, the support plate is pushed upward. The upward movement of the support plate will drive the card block fixed to it to move upward. The card block moving upward will squeeze the first spring, so that the card block obtains a force in the opposite direction. When the bayonet on the charging gun housing moves to the bottom of the card block, the card block moves downward under the action of the elastic force of the first spring, enters the bayonet and clamps the charging gun. When the charging gun needs to be taken away, the upper support plate is moved to make the support plate move upward, squeeze the first spring, and drive the card block to rise. At this time, the charging gun can be taken out.

[0011] A further improvement of the technical solution of the utility model is that: the snap-on component includes a shaft body, the shaft body is symmetrically arranged, the other end of the shaft body is fixedly connected to the support plate, the shaft body is slidably connected to the charging pile body, a second spring is arranged between the charging pile body and the support plate, the second spring is symmetrically arranged, one end of the second spring is fixedly connected to the charging pile body, the other end of the second spring is fixedly connected to the support plate, one end of the shaft body is fixedly connected to a slider, and the slider is slidably connected to the slide groove.

[0012] The above-mentioned technical solution is adopted. In this solution, when the charging gun enters, the support plate is pushed upward, causing the card block to move upward. The rising of the support plate will stretch the second spring, thereby driving the shaft body to move upward. The shaft body will drive the slider to move upward, so that the slider and the slide groove on the shell are on the same horizontal line. At this time, when the shell slider is moved again, it will enter the slide groove and be slidably connected with the slide groove. When the bayonet moves to the bottom of the card block, at this time, under the joint force of the first spring and the second spring, the card block and the slider move downward at the same time, the card block jams the buckle, and the slider can jam the T-shaped slide groove, so that the charging gun is completely jammed, achieving the effect of fixing the charging gun.

[0013] A further improvement of the technical solution of the utility model is that the distance between the clamping block and the insertion hole is smaller than the distance between the sliding block and the insertion hole.

[0014] With the above technical solution, since the linkage relationship between the fixing component and the buckle component is that the fixing component drives the buckle component to be linked, the charging gun needs to first interact with the block and then interact with the slider when entering the socket.

[0015] A further improvement of the technical solution of the utility model is that a slope is provided on the side of the card block close to the charging gun insertion.

[0016] The above technical solution is adopted, in which a slope is provided on the side of the card block close to the charging gun insertion, so that the charging gun can be directly and quickly inserted and stuck when inserted, and at the same time, the resistance generated by the charging gun in the moving direction can be reduced.

[0017] A further improvement of the technical solution of the utility model is that an insulating plate is fixedly connected inside the charging pile body.

[0018] The above technical solution adopts an insulating plate fixedly connected to the main body of the charging pile. The function of this insulating plate is to effectively block the current, thereby preventing accidents that cause electric shock or conduction. This ensures the safety and reliability of the charging pile during use and avoids potential risks caused by current leakage.

[0019] A further improvement of the technical solution of the utility model is that the outer surface of the shell and the inner surface of the box body are frosted.

[0020] The above technical solution is adopted, in which the outer surface of the shell and the inner surface of the box body are provided with fine frosting treatment. This special treatment increases the friction between the charging gun and the box body. Even if the charging gun and the box body are not completely stuck, the frosted surface provides additional grip, so the charging gun is difficult to accidentally fall off. The socket of the charging gun is effectively protected, avoiding potential damage caused by accidental falling.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a car DC charging pile with a plug protection function. Because the linkage relationship between the fixed component and the buckle component is that the fixed component drives the buckle component to be linked, the charging gun needs to first interact with the card block and then interact with the slider when entering the socket.

[0023] 2. The utility model provides a car DC charging pile with a plug protection function. A slope is provided on the side of the clamp block close to the charging gun insertion, so that the charging gun can be quickly inserted and stuck when inserted, and at the same time, the resistance generated by the charging gun in the moving direction can be reduced.

[0024] 3. The utility model provides a DC charging pile for automobiles with a plug protection function, in which an insulating plate is fixedly connected and arranged inside the main body of the charging pile. The function of this insulating plate is to effectively block the current, thereby preventing accidents that may cause electric shock or conduction. This ensures the safety and reliability of the charging pile during use and avoids potential risks caused by current leakage.

[0025] 4. The utility model provides a car DC charging pile with plug protection function. The outer surface of the shell and the inner surface of the box body are provided with fine frosting treatment. This special treatment increases the friction between the charging gun and the box body. Even if the charging gun and the box body are not completely stuck, the frosted surface provides additional gripping force, so the charging gun is difficult to fall accidentally. The socket of the charging gun is effectively protected to avoid potential damage caused by accidental falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example 1

[0035] like Figure 1 As shown, the utility model provides a car DC charging pile with a plug protection function, including a charging pile body 1, on which a charging gun 2 is symmetrically arranged, and a fixing component for fixing the charging gun 2 is symmetrically connected to the charging pile, and a shell 3 is provided at the plug connection of the charging gun 2, and the shell 3 is fixedly connected to the charging gun 2, and a slide groove 4 is symmetrically opened on the shell 3, and the slide groove 4 is set to a T shape, and a bayonet 5 is opened above the shell 3, and a buckle component for clamping the charging gun 2 is connected to the charging pile body 1.

[0036] In this embodiment, when charging is completed, the charging gun 2 will be placed at the socket on the charging pile body 1. At this time, the charging gun 2 is pushed into the socket. After being pushed to a certain distance, the fixing component starts to work under pressure, limiting the charging gun 2, and then drives the buckle component located at the back to start working. In this process, the fixing component and the buckle component continue to work in conjunction. When the fixing component completely fixes the charging gun 2, it will also drive the buckle component to clamp the charging gun 2, thereby achieving the purpose of linkage locking. When the charging gun 2 needs to be taken out, turn on the switch, so that the buckle component and the fixing component are no longer locked at the same time, and the charging gun 2 can be easily taken out.

[0037] like Figure 3 As shown, in the present embodiment, preferably, the fixing component includes a box body 6, a telescopic hole 7 is opened on the top of the box body 6, the box body 6 is fixedly connected to the charging pile body 1, a clamping block 8 is arranged inside the box body 6, the clamping block 8 is complementary to the clamping hole 5 opened on the shell 3, a support shaft 9 is fixedly connected to the top of the clamping block 8, the support shaft 9 is slidably connected to the charging pile body 1, a first spring 10 is arranged between the clamping block 8 and the charging pile body 1, one end of the first spring 10 is fixedly connected to the clamping block 8, and the other end of the first spring 10 is fixedly connected to the charging pile body 1, and a support plate 11 is fixedly connected to the end of the support shaft 9 away from the clamping block 8.

[0038] When the charging gun 2 enters, the support plate 11 is pushed upwards. The upward movement of the support plate 11 will drive the block 8 fixedly connected thereto to move upwards. The block 8 moving upwards will squeeze the first spring 10, so that the block 8 obtains a force in the opposite direction. When the bayonet 5 on the housing 3 of the charging gun 2 moves to the bottom of the block 8, the block 8 moves downwards under the elastic force of the first spring 10, enters the bayonet 5 and clamps the charging gun 2. When the charging gun 2 needs to be taken away, the upper support plate 11 is moved to make the support plate 11 move upwards, squeeze the first spring 10, and drive the block 8 to rise. At this time, the charging gun 2 can be taken out.

[0039] like Figure 4 As shown, preferably, the snap-fit ​​component includes a shaft body 12, the shaft body 12 is symmetrically arranged, the other end of the shaft body 12 is fixedly connected to the support plate 11, the shaft body 12 is slidably connected to the charging pile body 1, and a second spring 13 is arranged between the charging pile body 1 and the support plate 11, the second spring 13 is symmetrically arranged, one end of the second spring 13 is fixedly connected to the charging pile body 1, the other end of the second spring 13 is fixedly connected to the support plate 11, one end of the shaft body 12 is fixedly connected to a slider 14, and the slider 14 is slidably connected to the slide groove 4.

[0040] When the charging gun 2 enters, the support plate 11 is pushed upward, so that the block 8 moves upward. The rise of the support plate 11 will stretch the second spring 13, thereby driving the shaft 12 to move upward. The shaft 12 will drive the slider 14 to move upward, so that the slider 14 and the slide groove 4 on the shell 3 are on the same horizontal line. At this time, when the shell 3 is moved again, the slider 14 will enter the slide groove 4 and be slidably connected with the slide groove 4. When the bayonet 5 moves to the bottom of the block 8, at this time, under the joint force of the first spring 10 and the second spring 13, the block 8 and the slider 14 move downward at the same time, the block 8 clamps the buckle, and the slider 14 can clamp the T-shaped slide groove 4, so that the charging gun 2 is completely clamped, thereby achieving the effect of fixing the charging gun 2.

[0041] Example 2

[0042] like Figure 4 As shown, based on Example 1, the utility model provides a technical solution: preferably, the distance between the block 8 and the socket is smaller than the distance between the slider 14 and the socket.

[0043] In this embodiment, because the linkage relationship between the fixing component and the buckle component is that the fixing component drives the buckle component to be linked, the charging gun 2 needs to first interact with the block 8 and then interact with the slider 14 when entering the socket.

[0044] Example 3

[0045] like Figure 3As shown, based on Example 1, the utility model provides a technical solution: preferably, a slope 15 is provided on the side of the clamping block 8 close to the insertion of the charging gun 2.

[0046] In this embodiment, a slope 15 is provided on the side of the clamping block 8 close to the charging gun 2 for insertion, so that the charging gun 2 can be quickly inserted and stuck when inserted, and at the same time, the resistance generated by the charging gun 2 in the moving direction can be reduced.

[0047] Example 4

[0048] like Figure 4 As shown, based on Example 1, the utility model provides a technical solution: preferably, an insulating plate 16 is fixedly connected inside the charging pile body 1.

[0049] In this embodiment, an insulating plate 16 is fixedly connected to the main body of the charging pile. The function of this insulating plate 16 is to effectively block the current, thereby preventing accidents that may cause electric shock or conduction. This ensures the safety and reliability of the charging pile during use and avoids potential risks caused by current leakage.

[0050] Example 5

[0051] like Figure 3 As shown, based on Example 1, the utility model provides a technical solution: preferably, the outer surface of the shell 3 and the inner surface of the box body 6 are frosted.

[0052] In this embodiment, the outer surface of the housing 3 and the inner surface of the box body 6 are finely frosted, and this special treatment increases the friction between the charging gun 2 and the box body 6. Even if the charging gun 2 and the box body 6 are not completely stuck, the frosted surface provides additional gripping force, so that the charging gun 2 is difficult to accidentally fall off. The socket of the charging gun 2 is effectively protected, avoiding potential damage caused by accidental falling.

[0053] The following is a detailed description of the working principle of this automotive DC charging pile with plug protection function.

[0054] like Figure 1-5As shown, when charging is completed, the charging gun 2 will be placed at the socket on the charging pile body 1. At this time, the charging gun 2 is pushed into the socket. After being pushed to a certain distance, the fixing component starts to work under pressure, limiting the charging gun 2, and then drives the buckle component located at the back to start working. In this process, the fixing component and the buckle component continue to work in conjunction. When the fixing component completely fixes the charging gun 2, it will also drive the buckle component to clamp the charging gun 2, thereby achieving the purpose of linkage locking. When the charging gun 2 needs to be taken out, turn on the switch, so that the buckle component and the fixing component are no longer locked at the same time, and the charging gun 2 can be easily taken out. When the charging gun 2 enters, the support plate 11 is pushed upwards. The upward movement of the support plate 11 will drive the block 8 fixedly connected thereto to move upwards. The block 8 moving upwards will squeeze the first spring 10, so that the block 8 obtains a force in the opposite direction. When the bayonet 5 on the housing 3 of the charging gun 2 moves to the bottom of the block 8, the block 8 moves downwards under the elastic force of the first spring 10, enters the bayonet 5 and clamps the charging gun 2. When the charging gun 2 needs to be taken away, the upper support plate 11 is moved to make the support plate 11 move upwards, squeeze the first spring 10, and drive the block 8 to rise. At this time, the charging gun 2 can be taken out. When the charging gun 2 enters, the support plate 11 is pushed upward, so that the block 8 moves upward. The rise of the support plate 11 will stretch the second spring 13, thereby driving the shaft 12 to move upward. The shaft 12 will drive the slider 14 to move upward, so that the slider 14 and the slide groove 4 on the housing 3 are on the same horizontal line. At this time, the housing 3 is moved again, and the slider 14 will enter the slide groove 4 and slide with the slide groove 4. When the bayonet 5 moves to the right below the block 8, at this time, under the joint force of the first spring 10 and the second spring 13, the block 8 and the slider 14 move downward at the same time, the block 8 is stuck in the buckle, and the slider 14 can be stuck in the T-shaped slide groove 4, so that the charging gun 2 is completely stuck, and the charging gun 2 is fixed. Because the linkage relationship between the fixing component and the buckle component is that the fixing component drives the buckle component to be linked, the charging gun 2 needs to first produce an effect with the block 8 and then act with the slider 14 when entering the jack. A slope 15 is provided on the side of the card block 8 close to the insertion of the charging gun 2, so that the charging gun 2 can be quickly inserted and stuck when inserted, and at the same time, the resistance generated by the charging gun 2 in the direction of travel can be reduced. An insulating plate 16 is fixedly connected inside the main body of the charging pile. The function of this insulating plate 16 is to effectively block the current, thereby preventing accidents that cause electric shock or conduction to people. This ensures the safety and reliability of the charging pile during use and avoids potential risks caused by current leakage. The outer surface of the shell 3 and the inner surface of the box body 6 are provided with a fine frosting treatment. This special treatment increases the friction between the charging gun 2 and the box body 6. Even if the charging gun 2 is not completely stuck between the box body 6, the charging gun 2 is difficult to accidentally fall off because the frosted surface provides additional grip.The socket of the charging gun 2 is effectively protected to avoid potential damage caused by accidental falling.

[0055] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
