Description

TECHNICAL FIELD

[0001] The utility model relates to new energy automobile charging connector's technical field discloses a novel modular charging base. BACKGROUND

[0002] At present, most of the charging bases on the market are designed for specific brands or models of equipment, and the fast charging bases of different brands cannot be used universally. If a user has multiple devices of different brands, the user needs to prepare multiple different charging bases, which is inconvenient for the user. The design of the charging base needs to consider multiple factors, such as safety, compatibility, charging efficiency, etc., which makes the design process more complex, resulting in a longer design cycle. The internal structure of the charging base is integrated, the design is complex, and multiple technologies such as electronic circuits and communication protocols are involved, which requires a higher technical level of maintenance personnel.

[0003] For example, the existing Chinese patent application with publication number CN102904126B discloses an electric vehicle charging base, which includes a flange 3, a charging base body 14 and a charging base body rear cover 15, an LED indicator light assembly DZ for monitoring charging conditions and an electromagnetic lock assembly CZ. It also includes an electromagnetic lock working state detection assembly 10 and a manual unlocking device. The electromagnetic lock 6 of the electromagnetic lock assembly CZ is a linear translation motion electromagnetic lock with a main feature of electromagnetic lock core 6-6. It has the characteristics of reasonable and compact structure, convenient operation, safe and reliable charging, etc.

[0004] The above-mentioned utility model main part and flange are fixedly connected through the inner side surface of the charging base body flange. The connection mode between the components is affected by factors such as aging, vibration and corrosion during long-term use. It is not easy to disassemble and replace, and it is not convenient for later maintenance and after-sales maintenance. In addition, during the long-term frequent plugging and unplugging of the charging gun, the friction between the two can easily cause wear and tear, affecting the firmness and stability of the connection between the charging gun and the charging base. The conductive jack does not fully consider the future demand for high-power charging when designing. The material's conductivity, cross-sectional area and other parameters may not be able to meet the large current passing through, which can easily generate a large resistance heat, causing the temperature of the jack to rise.

[0043] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0045] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0046] Example 1

[0047] By modularizing the main components of the charging dock, the charging dock is divided into flange components, main body components, electronic lock components, and dust cap components, which improves production efficiency. Furthermore, the flange can be disassembled and replaced according to the needs of different users, increasing the flexibility of use and maintenance efficiency of the charging dock.

[0048] Furthermore, the modular design of the dust cap is used to combine different AC and DC main body structures to form a DC integrated unit.

[0049] like Figure 1 As shown, a novel modular charging dock housing includes:

[0050] 1. Square flange, 3. Charging base body, 4. Main body tail cover, and 5. Electronic lock;

[0051] A square flange 1 is located at one end of the charging base body 3, and a main body tail cover 4 is provided at the other end of the charging base body 3;

[0052] The square flange 1 serves as a support and connection component for the charging dock, providing an installation interface for the charging dock to be securely mounted on the mounting panel.

[0053] The square flange 1 secures the front flange gasket 203 and flange 204 to its four corners via square nuts 104, ensuring structural stability. Furthermore, since the front flange gasket 203 and flange 204 can be replaced with different sizes to meet specific needs, the square flange 1 can be adapted to flange mounting panels of various sizes, increasing the charging dock's versatility.

[0054] Electronic lock 5 is installed on one side of the modular charging base. Electronic lock 5 is used to lock the connection between the charging socket and the charging base. If the charging gun is inserted into the charging base, electronic lock 5 is used to prevent the charging gun from being pulled out accidentally, ensuring the safe charging process. When charging is completed or an abnormal situation occurs, electronic lock 5 can be unlocked under the action of a control signal, allowing the charging gun to be pulled out.

[0055] like Figure 2 As shown, the cap 2 makes it easy for users to plug and unplug the charging socket, and also protects the charging socket from external damage to a certain extent.

[0056] Connect the charging cable to the charging socket;

[0057] like Figure 3 As shown, the flip cap 103 seals the charging socket plug through the flip cap buckle 105. If the charging socket is not in use, the flip cap 103 is used to prevent dust, moisture, foreign objects, etc. from entering the charging socket, protecting the cleanliness and electrical performance of the plug. If the charging socket is in use, the flip cap 103 can be easily opened to expose the charging socket for connection operation.

[0058] Furthermore, the flip cap latch 105 is used to secure the flip cap 103, ensuring that the flip cap 103 tightly seals the charging port. When the flip cap 103 is closed, the flip cap latch 105 securely fastens the flip cap 103 onto the charging port, preventing the flip cap 103 from being accidentally opened.

[0059] The charging dock plug is connected to the charging dock body 3;

[0060] Example 2

[0061] A novel modular charging dock housing also includes,

[0062] like Figure 4 As shown, the square flange 1 also includes a flange 204, a square nut 104, and a front flange gasket 203;

[0063] Furthermore, the front flange gasket 203 is located at the top of the square flange 1 and is used to seal the modular charging base to prevent external moisture, dust and other substances from entering the charging base through the gap between the square flange 1 and the mounting panel. The size can be changed according to actual production and application needs to adapt to different installation environments and ensure good sealing effect under various installation conditions.

[0064] Furthermore, a flange 204 is installed at the other end of the front flange gasket 203;

[0065] Flange 204 is used in conjunction with the front flange gasket 203 and is fixed to the square flange 1 by square nuts 104. It is an important component of the square flange 1, providing an installation interface and structural support. By changing its size, flange 204 can be adapted to flange mounting panels of different sizes, enhancing the installation adaptability of the charging base.

[0066] Furthermore, the square nuts 104 are located at the four corners of the square flange 1 and are used to fix the front flange gasket 203 and the flange 204.

[0067] The square nut 104 is used to firmly fix the front flange gasket 203 and flange 204 to the square flange 1. By tightening the square nut 104, the stability and sealing of the square flange 1 structure are ensured, and the loosening or displacement of the components is prevented during use.

[0068] The front flange gasket 203 and flange 204 can be changed in size according to actual production and application requirements to fit flange mounting panels of different sizes, increasing the versatility of the charging base.

[0069] Example 3

[0070] A novel modular charging dock body, comprising

[0071] The charging base body 3 is used to carry the internal electrical connection components, realize the transmission of electrical energy, introduce external power and charge the electric vehicle. One end of the charging base body 3 is connected to a square flange 1 for installing the charging base, and the other end is provided with a main body tail cover 4 to seal and protect the internal wiring and other structures, and prevent dust, moisture and other substances from entering the charging base and affecting its normal operation.

[0072] Furthermore, the charging socket includes a first phase line 107, a neutral line 108, a third phase line 109, a control line 110, a protective grounding line 111, a first phase line 112, and a second phase line 113.

[0073] Among them, the first and second phase lines 107, the neutral line 108, and the third phase line 109 are located on one side of the charging socket;

[0074] Neutral line 108 is used to balance the three-phase voltage;

[0075] Control line 110, protective grounding line 111, first phase line 112, and second phase line 113 are located on the other side of the charging socket.

[0076] like Figure 5 As shown in the plan view of the charging socket body, the first and second phase lines 107 and the control line 110 are located at one end of the charging socket, the third phase line 109 and the second phase line 113 are located at the other end of the charging socket, and the neutral line 108, the protective ground line 111 and the first phase line 112 are located between the first and second phase lines 107 and the control line 110 and between the third phase line 109 and the second phase line 113.

[0077] The specific implementation method including the charging port includes:

[0078] The charging dock body 3 has a charging port inside;

[0079] For AC cables 1.5mm 2 -6mm 2 The cross-sectional area of ​​the cable is large. Inside the charging body (3), the charging body 3 has a sufficient cross-sectional area and good conductivity to adapt to it. For example, copper with high conductivity is used as the main material of the conductive circuit.

[0080] The charging socket includes various circuits, such as the first and second phase lines 107, the neutral line 108, the third phase line 109, the control line 110, the protective grounding line 111, the first phase line 112, and the second and second phase lines 113. Its design needs to meet the requirements of carrying AC currents from 10A to 32A, obtaining the minimum conductor cross-sectional area required for different currents. For example, when the current is 32A, based on the allowable current density of copper (generally 4-6 A / mm²),... 2Determine the minimum cross-sectional area of ​​the phase line to ensure it can safely carry current;

[0081] The neutral conductor 108 is used to balance the three-phase voltage. Its cross-sectional area can be designed according to the balance and unbalanced current of the three-phase power system. If the three phases are balanced, the current in the neutral conductor 108 is small. If the three phases are unbalanced, the neutral conductor 108 carries a larger current. The neutral conductor 108 takes into account the maximum unbalanced current situation to ensure that it can adapt to the current range of AC 10A-32A. Therefore, the neutral conductor 108 is located outside the protective grounding conductor 111 to ensure the elastic design of the cross-section of the neutral conductor 108.

[0082] Control line 110 is mainly used for transmitting charging control signals. Its current is relatively small, but the accuracy and stability of signal transmission must be ensured. Shielding can be used to prevent electromagnetic interference from affecting the control signals.

[0083] The design of the protective grounding wire 111 must ensure that the current can be quickly introduced into the ground in the event of a fault. Its cross-sectional area needs to meet the relevant electrical safety standards and is generally not less than half of the cross-sectional area of ​​the phase wire.

[0084] The main body tail cover 4 is installed at the other end of the charging base body 3 to seal and protect the charging base. The main body tail cover 4 also prevents external dust, moisture, foreign objects, etc. from entering the interior of the charging base, protects the internal electrical components and circuits, ensures the cleanliness and dryness of the interior of the charging base, helps maintain the reliability of electrical connections, and extends the service life of the charging base.

[0085] like Figure 6 As shown, the main body tail cover 4 includes an AC main body tail cover 401, wherein the AC main body tail cover 401 is used for an AC charging dock.

[0086] like Figure 7 The image shows the rear cover 401 of the main body of the communication device.

[0087] Example 4

[0088] A novel modular DC charging dock body includes a modular pull-out DC charging dock and a modular flip-top DC charging dock.

[0089] like Figure 7 As shown, a modular pull-out DC charging dock includes...

[0090] DC charging cap 503, main charging base body 501, DC charging tail cap 502, DC front flange sealing gasket 505, and DC square flange 506.

[0091] Furthermore, the DC charging dock features a modular design, including a DC charging cap 503, a main charging dock body 501, a DC charging tail cap 502, a DC front-mounted flange gasket 505, and a DC square flange 506. This modular design facilitates mass production of parts, and if a single module fails, it is easy to replace that single part, greatly reducing maintenance and testing costs. The addition of flanges (DC square flange 506 and flange 1) allows for the adaptation of flange mounting panels of different sizes, enhancing the charging dock's installation adaptability.

[0092] The front flange gasket 505 is located at the top of the square flange 506 and is used to seal the modular charging base to prevent external moisture, dust, etc. from entering the charging base through the gap between the square flange 506 and the mounting panel.

[0093] like Figure 8 The DC charging socket 507 shown includes S+ (CAN-H), S- (CAN-L line), charging confirmation socket CC2, positive socket DC+, negative socket DC-, grounding socket, auxiliary power positive socket A+, and auxiliary power negative socket A-.

[0094] Furthermore, the S+ (CAN-H), S- (CAN-L) lines, and charging confirmation jack CC2 are located on the same horizontal plane and at the top of the DC charging socket 505.

[0095] Furthermore, the positive terminal DC+, the negative terminal DC-, and the ground terminal are located between the S+ (CAN-H), S- (CAN-L line), the charging confirmation terminal CC2, the ground terminal, the auxiliary power supply positive terminal A+, and the auxiliary power supply negative terminal A-.

[0096] Furthermore, the grounding socket, the auxiliary power supply positive socket A+, and the auxiliary power supply negative socket A- are located at the bottom of the DC charging socket 505.

[0097] A modular flip-top DC charging dock includes,

[0098] The DC flip cap 508 seals the charging socket plug through the DC flip cap buckle 509. If the charging socket is not in use, the DC flip cap 508 is used to prevent dust, moisture, foreign objects, etc. from entering the charging socket, protecting the cleanliness and electrical performance of the plug. When the charging socket is in use, the DC flip cap 508 can be easily opened to expose the charging socket for connection operation.

[0099] Furthermore, the DC flip cap 508 is used to seal the DC charging socket 507.
