Description

Technical Field

[0001] The present application relates to the technical field of charging piles, and in particular to an openable AC charging pile that is easy to maintain, overhaul and install. Background Art

[0002] Charging piles are equipment that provide charging services specifically for new energy vehicles. Charging piles are connected to the power grid, and the charging port of new energy vehicles is connected to the charging interface of home charging piles, so that new energy vehicles can be charged. The charging pile and the vehicle confirm the charging parameters, such as battery capacity, charging current and charging voltage, and the charging pile starts charging the vehicle battery according to the needs of the vehicle and its own control strategy. During the charging process, the charging pile monitors the status of the vehicle battery in real time, such as battery voltage, current and temperature, and automatically adjusts the charging current and voltage according to the charging and discharging characteristics of the battery to ensure safe and efficient charging of the battery. At the same time, the charging pile will feed back the charging status information to the user in real time, and the user can check the charging progress through the display or mobile phone APP. When the vehicle battery is fully charged or the user stops charging, the charging pile automatically cuts off the charging power supply, ends the charging process, and notifies the user of the charging end information.

[0003] At present, the proportion of new energy vehicles in the world is gradually increasing, and the number of charging piles is also increasing. As a result, the installation and maintenance requirements of charging piles are also getting higher and higher. At present, most of the charging piles on the market have the back panel installed on the wall or column, the rear shell is connected to the back panel, the charging module is installed between the rear shell and the front shell, and then the front shell and the rear shell are connected by screws. During maintenance and overhaul, the charging pile needs to be removed from the wall or column for maintenance and overhaul. During the disassembly process, the technicians have to operate with power on, which causes inconvenience in operation and poses certain safety hazards. In addition, after the maintenance and overhaul is completed, the charging pile needs to be reassembled and installed on the wall or column, making the installation operation after maintenance and overhaul not convenient and quick enough. Summary of the invention

[0004] In order to facilitate the maintenance and overhaul of the charging pile, and to facilitate the reassembly of the charging pile after the maintenance and overhaul, the present application provides an openable AC charging pile that is easy to maintain, overhaul and install.

[0005] The present application provides an open-close AC charging pile that is easy to maintain, repair and install, and adopts the following technical solution: An open-and-close AC charging pile that is easy to maintain, overhaul and install, comprising a front shell, a receiving shell, a back plate, a charging module and a buckle assembly; The containing shell is connected to the back panel, the charging module is arranged in the containing shell, the front shell is rotatably connected to the containing shell, the containing shell is provided with an opening, and the front shell is used to open and close the opening of the containing shell; the snap-fitting component is arranged between the front shell and the containing shell, and the snap-fitting component snaps the front shell and the containing shell together.

[0006] By adopting the above technical solution, when maintenance and overhaul is required, the front shell and the containing shell are released from the buckle, and the front shell is pulled so that the containing shell can be opened, which is convenient for technicians to perform maintenance and overhaul on the internal charging module. This application does not require the charging pile to be removed from the wall or pillar, which can reduce the situation of live operation during the removal process and improve safety. After the maintenance and overhaul is completed, the front shell is pushed so that the buckle assembly buckles the front shell with the containing shell, so that the containing shell can be closed, and the charging pile can be assembled conveniently and quickly, improving operating efficiency.

[0007] Optionally, the snap-fit ​​assembly includes a fixed seat, a switch door buckle, an elastic member and a snap-fit ​​block; the fixed seat is connected to the front shell, the switch door buckle is slidably connected to the fixed seat, and the elastic member is respectively abutted against the fixed seat and the switch door buckle; the snap-fit ​​block is connected to the accommodating shell, and the switch door buckle is snapped with the snap-fit ​​block.

[0008] By adopting the above technical solution, the design of the elastic member ensures the close contact between the switch door buckle and the buckle stopper, and enhances the stability of the structure. The cooperation between the switch door buckle and the buckle stopper realizes the rapid locking between the front shell and the receiving shell.

[0009] Optionally, the snap-fit ​​stopper is provided with an inclined surface, and when the front shell is pulled, the switch door buckle slides along the inclined surface, and the inclined surface separates the switch door buckle from the snap-fit ​​stopper.

[0010] By adopting the above technical solution, the snap-fit ​​block is provided with a bevel. When the front shell needs to be opened for maintenance and repair, it is only necessary to pull the front shell, and the bevel separates the door switch buckle from the snap-fit ​​block, thereby reducing the difficulty of disassembly and assembly and improving the convenience and safety of operation.

[0011] Optionally, the switch door buckle is connected to a pressure sensor, and the pressure sensor is electrically connected to the charging module; when the switch door buckle is engaged with the engagement block, the switch door buckle presses against the pressure sensor.

[0012] By adopting the above technical solution, when the switch door buckle is buckled with the buckle block, the switch door buckle will press against the pressure sensor, thereby triggering the pressure sensor to send a signal to the charging module, which can effectively detect whether the front shell is correctly closed and locked, ensuring the safe operation of the charging pile. When the front shell is opened, the front shell drives the switch door buckle to separate from the buckle block. At this time, the switch door buckle does not abut against the pressure sensor, and the pressure sensor sends a signal to the charging module, which can cut off the power of the charging module and improve the safety after opening the front shell.

[0013] Optionally, the back plate includes a connecting plate, an inserting plate and a supporting plate, wherein the inserting plate is connected to one side of the connecting plate, and the supporting plate is connected to the other side of the connecting plate; The accommodating shell comprises a middle shell and a rear shell, the middle shell is connected to the rear shell, the rear shell is provided with an inserting slot, the inserting piece is inserted into the inserting slot; the supporting plate supports the rear shell, and the supporting plate is detachably connected to the rear shell.

[0014] By adopting the above technical solution, the back panel is first installed on the wall or column, and then the plug-in slot is plugged into the plug-in piece, and the supporting plate is detachably connected to the rear shell, thereby realizing the quick installation of the containing shell and the back panel, and the back panel can stably support the containing shell.

[0015] Optionally, the charging module includes a main control module and an electric control module, the main control module is connected to the front shell, the electric control module is connected to the containing shell, and the main control module and the electric control module are electrically connected.

[0016] By adopting the above technical solution, when the front shell is opened, the main control module moves with the front shell, so that the main control module is moved out of the accommodating shell, which makes it convenient for technicians to maintain and repair the main control module and the electric control module respectively.

[0017] Optionally, a sealing rib is connected to the opening edge of the containing shell, and a sealing foam is connected to the front shell, and the sealing rib is used to abut against the sealing foam.

[0018] By adopting the above technical solution, the sealing rib is connected to the opening edge of the containing shell, the sealing foam is connected to the front shell, and the sealing rib abuts against the sealing foam to form a sealing structure, which effectively reduces external dust and moisture from entering the interior of the charging pile and improves the protection performance of the charging pile.

[0019] Optionally, the containment shell is provided with a heat dissipation hole, and a trigger drive component and a blocking component are arranged in the containment shell, and the blocking component blocks the heat dissipation hole; the trigger drive component is heated to drive the blocking component to move, so that the blocking component opens the heat dissipation hole.

[0020] By adopting the above technical solution, the blocking component blocks the heat dissipation hole, which can reduce the entry of external dust and impurities into the charging pile. The charging pile generates heat during operation, and the heat causes the blocking component of the trigger drive component to move, thereby causing the blocking component to open the heat dissipation hole, effectively dissipating heat by air convection, and reducing safety hazards and performance degradation caused by overheating.

[0021] Optionally, the blocking assembly includes a blocking block and a connecting strip, the blocking block is connected to the connecting strip, and the blocking block blocks the heat dissipation hole; The trigger drive assembly includes a support frame, a temperature-controlled switch and a connecting rod, the support frame is connected to the containing shell, and the connecting strip is slidably connected to the support frame; the temperature-controlled switch is connected to the support frame, and the connecting rod is respectively connected to the connecting strip and the temperature-controlled switch; when the temperature-controlled switch is heated, the temperature-controlled switch drives the connecting rod to move.

[0022] By adopting the above technical solution, when the temperature control switch is heated due to the internal heating of the charging pile, the temperature control switch will drive the connecting rod to move, and the connecting rod will drive the blocking assembly to move, so that the blocking block opens the heat dissipation hole, which can carry out air convection, effectively reduce the internal temperature of the charging pile, and reduce the damage caused by overheating. When the temperature of the charging pile drops to a safe range, the temperature control switch is reset, and the blocking block re-seals the heat dissipation hole, maintaining good sealing performance, reducing external dust and impurities from entering the charging pile, and improving the reliability and service life of the equipment.

[0023] Optionally, a hygroscopic expansion block is connected to the support frame, and the hygroscopic expansion block is used to abut against the connecting strip; when the hygroscopic expansion block absorbs moisture, the hygroscopic expansion block pushes the blocking component to move in a direction of blocking the heat dissipation hole.

[0024] By adopting the above technical solution, the hygroscopic expansion block can absorb moisture in the air inside the charging pile and keep the air inside the charging pile dry. When the trigger driving component opens the heat dissipation hole through the blocking component, if the humidity of the air entering from the outside is high, the hygroscopic expansion block absorbs moisture and expands, and the hygroscopic expansion block pushes the blocking component to move in the direction of blocking the heat dissipation hole, and can control the opening of the heat dissipation hole according to the humidity, and even make the blocking component completely block the heat dissipation hole, reducing the impact of moisture in the outside air on the inside of the charging pile.

[0025] In summary, the present application includes at least one of the following beneficial effects: 1. The front shell can be quickly opened and closed by snapping together the components, so that internal maintenance and repair can be carried out without disassembling the entire charging pile, which simplifies the operation process, reduces the time and labor required for disassembling and assembling the charging pile, and improves work efficiency; 2. When the charging pile is heated, the temperature control switch can automatically control the blocking component to open the heat dissipation holes to ensure timely and effective heat dissipation, reduce damage to the components of the charging pile caused by high temperature, and extend the service life of the charging pile; 3. The hygroscopic expansion block can automatically adjust the opening of the heat dissipation holes when the air humidity is high, reducing the impact of the humid environment on the internal components of the charging pile, and further improving the safety and reliability of the charging pile.

[0037] Embodiment 2:

[0038] Embodiment 2 of the present application provides an openable AC charging pile that is easy to maintain, repair and install. The difference between Embodiment 2 of the present application and Embodiment 1 is that: refer to Figure 6 , the buckle block 54 is fixedly connected with a pressure sensor 56, and the pressure sensor 56 is electrically connected to the charging module 4. When the switch door buckle 52 is buckled with the buckle block 54, the switch door buckle 52 presses against the pressure sensor 56, and the pressure sensor 56 can detect the pressure and transmit the signal to the charging module 4, so that the charging module 4 can work normally. When the switch door buckle 52 is separated from the buckle block 54, the pressure sensor 56 does not detect the pressure, which indicates that the technician is repairing the charging pile, or the charging pile is accidentally opened. At this time, the charging module 4 is powered off, thereby improving safety.

[0039] Embodiment 3:

[0040] Embodiment 3 of the present application provides an openable AC charging pile that is easy to maintain, repair and install. The difference between Embodiment 3 of the present application and Embodiment 2 is that: refer to Figure 7 and Figure 8, a trigger drive assembly 9 and a blocking assembly 10 are arranged inside the rear shell 22, and the trigger drive assembly 9 includes a support frame 91, a temperature control switch 92, a connecting rod 93 and a hygroscopic expansion block 94. The support frame 91 is fixedly connected to the rear shell 22, and the temperature control switch 92 is fixedly connected to the support frame 91. In this embodiment, the temperature control switch 92 specifically adopts a mechanical temperature control switch, the temperature control switch 92 has a moving end, and the connecting rod 93 is fixedly connected to the moving end of the temperature control switch 92. The charging module 4 will emit heat when working. When the heat emitted by the charging module 4 reaches the predetermined value of the temperature control switch 92, the temperature control switch 92 drives the connecting rod 93 to move upward.

[0041] refer to Figure 7 and Figure 8 The blocking assembly 10 includes a blocking block 101 and a connecting strip 102. The blocking block 101 is provided with a plurality of blocking blocks 101, and the plurality of blocking blocks 101 are fixedly connected to the connecting strip 102. In the present embodiment, a heat dissipation hole 222 is provided on the bottom side of the rear shell 22. In other implementations of the present embodiment, heat dissipation holes 222 may also be provided on other sides of the rear shell 22. The blocking block 101 corresponds one-to-one to the plurality of heat dissipation holes 222, and the blocking block 101 can block the heat dissipation holes 222. The connecting rod 93 is fixedly connected to the connecting strip 102, the connecting rod 93 passes through the support frame 91 and is slidably connected to the support frame 91, and the connecting strip 102 is slidably connected to the support frame 91. When the temperature control switch 92 is heated, the temperature control switch 92 can drive the blocking assembly 10 to move through the connecting rod 93, so that the blocking block 101 opens the heat dissipation holes 222, which can be beneficial to the heat dissipation inside the charging pile. When the temperature inside the charging pile returns to normal, the temperature control switch 92 is reset, thereby driving the blocking block 101 to block the heat dissipation hole 222, thereby reducing the entry of external dust and impurities into the charging pile.

[0042] refer to Figure 7 and Figure 8 A hygroscopic expansion block 94 is fixedly connected to the support frame 91. When the temperature control switch 92 drives the blocking block 101 to open the heat dissipation hole 222, the connecting strip 102 abuts against the hygroscopic expansion block 94, and the hygroscopic expansion block 94 can absorb moisture in the air. When the humidity of the air entering the charging pile is high, the hygroscopic expansion block 94 absorbs moisture and expands. The hygroscopic expansion block 94 pushes the blocking block 101 to move downward through the connecting strip 102, thereby controlling the opening of the heat dissipation hole 222 by the blocking block 101, and even makes the blocking block 101 block the heat dissipation hole 222, thereby preventing moisture from affecting the internal components of the charging pile. The heat generated inside the charging pile can heat the hygroscopic expansion block 94, or after the moisture in the hygroscopic expansion block 94 evaporates naturally, the hygroscopic expansion block 94 can restore its original volume, so that the trigger drive component 9 can normally open the heat dissipation hole 222 through the blocking component 10 during the next charging.

[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.
