Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, specifically to a DC charging pile with a quickly replaceable charging handle and handle components. Background Technology

[0002] DC charging stations are equipped with charging handles for charging batteries. However, since the charging handles require manual plugging and unplugging, they are easily damaged. Replacing the handle requires disassembling the charging station and rewiring, which is time-consuming. Furthermore, the charging gun consists of cables, handles, plugs, and other parts, each with a different probability of failure. Replacing the entire charging handle due to the failure of a single part is costly. Therefore, a charging gun with quickly replaceable parts needs to be designed to solve the problems of high labor and material costs associated with replacing the charging gun, as well as quality issues caused by disassembling and reassembling the charging station. In addition, the mains wiring of the charging station and the charging gun wiring are located in the same cavity, which can easily affect adjacent wiring when disassembling or replacing the mains wiring or the charging gun wiring. The prior art CN115765141A provides a charging pile distribution box with switchable power supply, including a charging pile distribution box body, a quick access device, and a switching module. The quick access device and the switching module are located inside the charging pile distribution box body. The switching module is a single-pole double-throw switch. The pivot end of the single-pole double-throw switch is connected to the mains transformer, and the moving end is connected to the charging pile busbar and the quick access device respectively. The quick access device includes a generator vehicle quick access port, a generator vehicle side control switch, and a generator vehicle side line energization indicator module connected in sequence. The output end of the generator vehicle side line energization indicator module is connected to the single-pole double-throw switch. The charging pile distribution box body is also provided with a charging pile side line energization indicator module. The input end of the charging pile side line energization indicator module is connected to the single-pole double-throw switch, and the output end is connected to the charging pile busbar. The charging pile busbar is connected to several charging piles through several charging pile control switches. The charging pile distribution box body is also provided with a surge arrester. One end of the surge arrester is connected to the input end of the charging pile side line energization indicator through a protection switch, and the other end is grounded. The inventors believe that there is significant room for improvement in the existing technology. Utility Model Content

[0003] The purpose of this invention is to provide a DC charging pile with independent AC power and charging gun wiring, as well as a quick-detachable charging handle. The independent AC power and charging gun wiring reduce the risk of quality problems caused by disassembling and assembling the charging pile. Secondly, it reduces the labor and material costs required to replace the charging gun.

[0004] A DC charging station with a quickly replaceable charging handle and handle components includes a charging handle and a DC charging station. The DC charging station includes a first stop that divides the DC charging station into a charging gun wiring cavity and a mains power input wiring cavity. The charging gun wiring cavity and the mains power input wiring cavity are independent of each other. The charging handle includes a charging gun cable, which is detachably connected to the charging handle and the charging gun wiring cavity. The charging gun wiring cavity and the mains power input wiring cavity are independent, preventing contact with internal components of the mains power input wiring cavity when replacing the charging gun or operating the charging wiring cavity. They have independent wiring space, and physical isolation between the high-voltage DC charging gun wiring cavity and the low-voltage AC mains power input wiring cavity avoids quality problems of other components caused by manual operation. When repairing the mains power line, the operator only contacts the low-voltage cavity, physically isolated from high-voltage components, eliminating the risk of electric shock. It should be noted that the high voltage applied by the charging gun refers to a voltage higher than the conventional mains voltage.

[0005] Preferably, the end of the charging handle closest to the charging gun cable is the tail end, which has a retaining sleeve. The retaining sleeve is conical, with its small end connected to the charging handle and its large end fitted over the charging gun cable. The charging gun cable passes through the retaining sleeve, and the retaining sleeve is screwed tightly onto the tail end of the charging handle. The retaining sleeve covers the connection between the charging gun cable and the charging handle, and it serves as a waterproof and anti-theft device. The conical structure creates a gradient stiffness transition at the connection between the cable and the handle, allowing the bending stress caused by the cable's own weight to be evenly transferred from the cable to the handle.

[0006] Preferably, the fixing sleeve has a first fixing member in the radial direction, which fixes the cable and the fixing sleeve from the outside of the fixing sleeve. The first fixing member is an anti-theft screw. After the fixing sleeve is tightened with the tail thread of the charging handle, the anti-theft screw restricts the rotation of the fixing sleeve and the cable relative to the charging handle. The anti-theft screw plays a role in preventing theft and loosening, and prevents the charging cable from being removed without the use of professional tools.

[0007] Preferably, the end of the charging handle furthest from the charging gun cable is the head, and the head of the charging handle is equipped with a plug, which is detachably connected to the charging handle.

[0008] Preferably, the plug is provided with a second fixing member in the axial direction, which secures the plug and the head of the charging handle from one side of the plug. Removing the fixing member between the plug and the charging handle in the axial direction allows the plug to be quickly separated from the charging handle. This axial fixing and separation process avoids damage to the terminals of the plug and the charging handle while ensuring rapid plug separation.

[0009] Preferably, the plug has a flange around its outer side, and the second fixing member passes through the flange to connect to the charging handle. By providing a flange at the plug, the flange covers the connection between the plug and the charging handle, ensuring the waterproofness of the connection; the second fixing member axially connects the charging handle and the plug through the flange, avoiding radial connection that could cause misalignment of the plug and the charging handle and compress the internal terminals, and using axial fixing to ensure the coaxiality of the plug and the charging handle.

[0010] Preferably, a sealing groove is provided at the connection between the plug and the charging handle. The sealing groove is located on the outer ring of the plug flange, and a sealing ring is provided inside the sealing groove. The sealing groove and the sealing ring further enhance the sealing effect of the flange at the connection between the plug and the charging handle, ensuring the waterproofness of the connection.

[0011] Preferably, the DC charging station also includes a waterproof plug, which includes an AC power access cable that connects the AC power access junction box and the waterproof plug.

[0012] Preferably, the DC charging pile also includes a cover plate, which is shared by the mains power connection cavity and the charging gun connection cavity. During maintenance, only the same cover plate needs to be opened, which allows for quick testing of the mains power connection cable and the charging gun cable; only one fixing point for the cover plate needs to be set and a well-sealed cover plate needs to be installed, reducing the complexity of charging pile production and installation.

[0013] Preferably, the charging gun cable and the mains power access cable are led out from the same side of the mains power access wiring cavity and the charging gun wiring cavity. This avoids the need for cable trays on both sides of the DC charging pile, saving internal space; it also avoids the need for external cable trays on both sides during construction, allowing for cable shielding and reducing installation complexity.

[0014] This invention solves the problems of replacing the entire charging handle due to damage to a single part, which is costly in terms of labor and materials. It also addresses the issue that the charging pile's mains wiring and charging gun wiring are located in the same cavity, making it easy to affect adjacent wiring when disassembling or replacing the mains or charging gun wiring. The invention offers the following advantages: a fixing sleeve shields the connection between the charging gun cable and the charging handle, providing waterproofing and anti-theft protection; a tapered structure achieves a gradient stiffness transition at the cable-handle connection, ensuring that the bending stress caused by the cable's weight is evenly transferred from the cable to the handle; axial fixing ensures the coaxiality of the plug and charging handle, preventing radial connections from causing misalignment and compressing the internal terminals; it avoids the need for cable trays on both sides of the DC charging pile, saving internal space; and it eliminates the need for external cable routing on both sides during construction, allowing for cable shielding and reducing installation complexity.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] like Figure 1As shown, a DC charging station with a quickly replaceable charging handle and handle components includes a charging handle 4 and a DC charging station 8. The DC charging station 8 includes a first stop that divides the DC charging station 8 into a charging gun wiring cavity 9 and a mains power input wiring cavity 10. The charging gun wiring cavity 9 and the mains power input wiring cavity 10 are independent of each other. The charging handle 4 includes a charging gun cable 5, which is detachably connected to the charging handle 4 and the charging gun wiring cavity 9. The charging gun wiring cavity 9 and the mains power input wiring cavity 10 are independent of each other. When replacing the charging gun or operating the charging gun wiring cavity 9, the internal components of the mains power input wiring cavity will not be touched. There is an independent wiring space, and the high-voltage DC charging gun wiring cavity 9 and the low-voltage AC mains power input wiring cavity 10 are physically isolated to avoid quality problems of other components caused by manual operation. It should be noted that the high voltage of the charging gun refers to a voltage higher than the mains voltage.

[0027] If the charging gun cable 5 is damaged and needs to be replaced, remove the first fixing part 7, loosen the fixing sleeve 6, pull out the charging gun cable 5, and then disconnect the charging gun cable 5 inside the charging gun wiring cavity 9. After troubleshooting, reconnect the charging gun cable 5.

[0028] like Figure 2 As shown, the DC charging pile 8 also includes a waterproof plug. The waterproof plug 2 includes an AC power access cable 11, which connects the AC power access wiring cavity 10 and the waterproof plug 12.

[0029] The DC charging pile 8 also includes a cover plate 13, which is shared by the mains power access wiring cavity 10 and the charging gun wiring cavity 9. During maintenance, only the same cover plate 13 needs to be opened, which can quickly complete the testing of the mains power access cable 11 and the charging gun cable 5; only one fixing point of the cover plate 13 needs to be set and a well-sealed cover plate 13 needs to be installed, which reduces the complexity of charging pile production and installation.

[0030] Combination Figure 1 and Figure 2 As shown, the charging gun cable 5 and the mains power access cable 11 are led out from the same side of the mains power access wiring cavity 10 and the charging gun wiring cavity 9. The DC charging pile 8 only needs to have a hole opened on one side and a cable channel set, avoiding the need to set cable channels on both sides of the DC charging pile, thus saving internal space of the DC charging pile 8; avoiding the need to open grooves on both sides or dig up the ground for wiring during construction, and also facilitating the uniform setting of cable shielding layers, reducing installation complexity and construction costs.

[0031] Combination Figure 3 , Figure 4 and Figure 7As shown, the end of the charging handle 4 closest to the charging gun cable 5 is the tail. The tail of the charging handle 4 has a fixing sleeve 6, which is conical. The small end of the fixing sleeve 6 connects to the charging handle 4, and the large end of the fixing sleeve 6 is fitted over the charging gun cable 5. The tail of the charging handle 4 and the charging gun cable 5 are detachably connected. The charging gun cable 5 passes through the fixing sleeve 6, and the fixing sleeve 6 is threaded tightly onto the tail of the charging handle 4. The fixing sleeve 6 shields the connection between the charging gun cable 5 and the charging handle 4, and has waterproof and anti-theft functions. The conical structure achieves a gradient stiffness transition at the connection between the cable and the handle, allowing the bending stress caused by the cable's own weight to be evenly transmitted from the cable to the handle.

[0032] If the charging handle 4 is damaged and needs to be replaced, first remove the second fixing part 1, pull out the plug 2 in the axial direction, then remove the first fixing part 7, loosen the fixing sleeve 6, and then disconnect the charging gun cable 5. Install the plug 2 and cable onto the new charging handle 4 and tighten the first fixing part 7 and the second fixing part 1 in sequence.

[0033] like Figure 3 As shown, a first fixing member 7 is provided in the radial direction of the fixing sleeve 6. The first fixing member 7 fixes the charging gun cable 5 and the fixing sleeve 6 from the outside of the fixing sleeve 6. The first fixing member 7 is an anti-theft screw. After the fixing sleeve 6 is tightened with the tail thread of the charging handle 4, the anti-theft screw restricts the rotation of the fixing sleeve 6 and the cable relative to the charging handle 4. The anti-theft screw plays a role in preventing theft and loosening, and prevents the charging gun cable 5 from being stolen and removed without the use of professional tools.

[0034] like Figure 6 As shown, the end of the charging handle 4 away from the charging gun cable 5 is the head, and the head of the charging handle 4 is provided with a plug 2, which is detachably connected to the head of the charging handle 4.

[0035] like Figure 4 As shown, the plug 2 is provided with a second fixing member 1 in the axial direction. The second fixing member 1 fixes the head of the plug 2 and the charging handle 4 from one side of the plug 2. By removing the fixing member between the plug 2 and the charging handle 4 in the axial direction, the plug 2 can be quickly separated from the charging handle 4 in the axial direction. The axial fixing and separation process of the plug 2 can avoid damage to the terminals of the plug 2 and the charging handle 4, and also ensure the rapid separation of the plug 2.

[0036] like Figure 5 As shown, a flange surrounds the outer side of the plug 2, and the second fixing member 1 passes through the flange to connect to the charging handle 4. By setting a flange at the plug 2, the flange covers the connection between the plug 2 and the charging handle 4, ensuring the waterproofness of the connection; the second fixing member 1 axially connects the charging handle 4 and the plug 2 through the flange, avoiding radial connection that would cause misalignment of the plug 2 and the charging handle 4 and press against the internal terminals, and using axial fixing to ensure the coaxiality of the plug 2 and the charging handle 4.

[0037] If plug 2 is damaged and needs to be replaced, remove the anti-theft screw, i.e. the second fixing part 1, and pull plug 2 out in the radial direction to avoid damaging the terminal. After replacing plug 2, tighten the anti-theft screw to fix it and complete the replacement operation.

[0038] A sealing groove is provided at the connection between the plug 2 and the charging handle 4. The sealing groove is located on the outer ring of the flange of the plug 2, and a sealing ring 3 is provided inside the sealing groove. The sealing groove and the sealing ring 3 further enhance the sealing effect of the flange on the connection between the plug 2 and the charging handle 4, ensuring the waterproofness of the connection.

[0039] This invention solves the problems of replacing the entire charging handle 4 due to damage to a part, which is costly in terms of labor and materials; and the fact that the mains wiring and charging gun wiring of the charging pile are located in the same cavity, which can easily affect adjacent wiring when disassembling or replacing the mains wiring or charging gun wiring. It also has the following advantages: the fixing sleeve 6 shields the connection between the charging gun cable 5 and the charging handle 4, and the fixing sleeve 6 has waterproof and anti-theft functions; the conical structure achieves a gradient stiffness transition at the connection between the cable and the handle, allowing the bending stress caused by the cable's own weight to be evenly transmitted from the cable to the handle; axial fixing ensures the coaxiality of the plug 2 and the charging handle 4, avoiding radial connection that could cause misalignment and pressure on the internal terminals; it avoids the need for cable trays on both sides of the DC charging pile, saving internal space of the DC charging pile 8; and it avoids the need for external cable trays on both sides during construction, allowing for cable shielding and reducing installation complexity.

[0040] The above embodiments and / or implementation methods are merely preferred embodiments and / or implementation methods for implementing the present utility model, and are not intended to limit the implementation methods of the present utility model in any way. Any person skilled in the art can make some modifications to other equivalent embodiments without departing from the scope of the technical means disclosed in the present utility model, but these should still be regarded as the same technology or embodiments as the present utility model.
