Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of charging piles, and in particular to a charging pile. BACKGROUND
[0002] In the related art, various devices in the charging pile, such as charging busbars, power distribution devices, control single boards, metering devices, monitoring devices, and busbars, occupy a large space inside the charging pile, resulting in a large occupied area of the charging pile, which is not conducive to the production, installation, and maintenance of the charging pile. CONTENT OF THE UTILITY MODEL
[0003] The present application provides a charging pile to reduce the occupied space of the charging pile.
[0004] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:
[0005] The present application provides a charging pile, which comprises a shell, a support, a first conductive connecting piece, a second conductive connecting piece, a switch module, and a control module. The support is arranged on the inner wall of the shell, and comprises a first plate and a second plate arranged at an angle. The first conductive connecting piece is used to connect a power supply, and the second conductive connecting piece is used to connect a charging gun. The switch module is electrically connected to the first conductive connecting piece and the second conductive connecting piece. The switch module has a conduction state and a disconnection state. In the conduction state, the first conductive connecting piece and the second conductive connecting piece are electrically connected, and in the disconnection state, the first conductive connecting piece and the second conductive connecting piece are not electrically connected. The control module is used to control the switch module to switch between the conduction state and the disconnection state. The first conductive connecting piece, the second conductive connecting piece, and the switch module are arranged on the first plate, and the control module is arranged on the second plate.
[0006] In the charging pile provided by the present application, the power supply is used to supply power to the charging pile, and the charging pile is used to supply power to the charging gun. The control module can control the switch module to switch between the conduction state and the disconnection state. When the switch module is in the conduction state, the current of the power supply can be transmitted to the charging gun through the first conductive connecting piece and the second conductive connecting piece. The charging gun can be connected to an electric vehicle to charge the electric vehicle. When the switch module is in the disconnection state, the first conductive connecting piece and the second conductive connecting piece are not electrically connected, and the current of the power supply cannot be transmitted to the charging gun, so the charging gun cannot charge the electric vehicle.
[0007] The support is arranged on the inner wall of the shell. The support comprises a first plate and a second plate arranged at an angle, that is, the first plate and the second plate are located in different planes, i.e., the first plate and the second plate form a space structure. Compared with a paving arrangement, the first conductive connecting member, the second conductive connecting member and the switch module are arranged on the first plate, and the control module is arranged on the second plate. On the one hand, the space structure formed by the first plate and the second plate can be effectively utilized in different directions, so that the first conductive connecting member, the second conductive connecting member, the switch module and the control module are arranged more compactly, thereby reducing the size of the charging pile, i.e., reducing the occupied space of the charging pile. On the other hand, it is beneficial to realize functional partitioning and avoid mutual interference between the devices on the first plate and the devices on the second plate.
[0008] In addition, the first conductive connecting member, the second conductive connecting member, the switch module or the control module can be conveniently installed and maintained. For example, in the case of a small installation space, the first conductive connecting member, the second conductive connecting member, the switch module and the control module are first installed on the support, and then the support is installed on the inner wall of the shell, which is convenient for workers to install, saves time and improves productivity. For example, during operation, the support is first disassembled, and then the first conductive connecting member, the second conductive connecting member, the switch module or the control module on the support is replaced and maintained.
[0009] In an optional embodiment, the charging pile further comprises a fault protection module. The fault protection module is arranged on the first plate, and the fault protection module is electrically connected to the switch module and the second conductive connecting member, and is used to be turned off when the current value flowing through the fault protection module is greater than the current threshold value of the fault protection module. The withstand voltage specification of the fault protection module is greater than the withstand voltage specification of the switch module.
[0010] The current threshold value of the fault protection module, i.e., the maximum current value that the fault protection module can withstand. In order to ensure the safety of the circuit, the current threshold value of the fault protection module is less than or equal to the maximum current value that the circuit for supplying power to the charging gun (i.e., the loop formed by the power supply, the charging pile and the charging gun) can withstand.
[0011] For example, when an abnormal situation such as short circuit or overload occurs in the circuit for supplying power to the charging gun, the current value flowing through the fault protection module is greater than the current threshold value of the fault protection module, and the fault protection module can be quickly turned off to quickly disconnect the circuit, thereby protecting the charging gun and the devices in the circuit for supplying power to the charging gun.
[0012] The withstand voltage specification of the fault protection module, i.e., the maximum voltage value that the fault protection module can withstand when working normally. The withstand voltage specification of the switch module, i.e., the maximum voltage value that the switch module can withstand when working normally.
[0013] In this example, the fault protection module is electrically connected to the switch module and the second conductive connecting piece, and the voltage resistance specification of the fault protection module is greater than that of the switch module. That is, in the circuit, the fault protection module is located between the switch module and the second conductive connecting piece. Since the voltage of the circuit between the switch module and the second conductive connecting piece is higher than that of the circuit at the switch module. Compared with the switch module, the fault protection module is arranged at a position with higher voltage, and the greater the voltage value, the faster the response speed of the fault protection module, the shorter the response time, which can better protect the circuit and ensure the safe operation of the circuit.
[0014] In addition, the fault protection module can be replaced conveniently. For example, if the fault protection module is electrically connected to the first conductive connecting piece and the switch module, the worker may be electrocuted during the replacement of the fault protection module. By locating the fault protection module between the switch module and the second conductive connecting piece, the switch module is turned off first before the replacement of the fault protection module, so that the worker can be prevented from being electrocuted, and the safety is higher.
[0015] In an optional embodiment, the first conductive connecting piece includes a positive input connecting piece and a negative input connecting piece. The second conductive connecting piece includes a positive output connecting piece and a negative output connecting piece. The switch module includes a first switch module and a second switch module. The positive input connecting piece, the first switch module, the fault protection module and the positive output connecting piece are sequentially arranged along a first direction, the fault protection module is connected to the first switch module through a third conductive connecting piece, and the fault protection module is connected to the positive output connecting piece. The negative input connecting piece, the second switch module and the negative output connecting piece are sequentially arranged along the first direction.
[0016] The positive input connecting piece is used to connect the positive pole of the power supply, and the negative input connecting piece is used to connect the negative pole of the power supply. The positive output connecting piece is used to connect the positive pole of the charging gun, and the negative output connecting piece is used to connect the negative pole of the charging gun.
[0017] The current flows out from the positive pole of the power supply, sequentially passes through the positive input connecting piece, the first switch module, the third conductive connecting piece, the fault protection module, the positive output connecting piece, is transmitted to the positive pole of the charging gun, and then is transmitted to the negative pole of the charging gun, and sequentially passes through the negative input connecting piece, the second switch module and the negative output connecting piece, and is transmitted to the negative pole of the charging gun to form a loop.
[0018] In this example, since the voltage of the circuit between the positive input connecting piece and the positive pole of the charging gun is greater than that of the circuit between the negative input connecting piece and the negative pole of the charging gun, the fault protection module is placed between the positive input connecting piece and the positive pole of the charging gun, the voltage value of the fault protection module is increased, the response speed of the fault protection module is further improved, and the response time of the fault protection module is further shortened, which is beneficial to improve the operation safety of the circuit.
[0019] The positive input connecting piece, the first switch module, the fault protection module, and the positive output connecting piece are sequentially arranged along the first direction. The negative input connecting piece, the second switch module, and the negative output connecting piece are sequentially arranged along the first direction.
[0020] In this way, the devices on the first plate can be arranged in an orderly and neat manner on the first plate. On the one hand, the devices on the first plate can be arranged more compactly, and the first plate occupies less space, which can be used to reduce the occupied space of the charging pile. On the other hand, it is also convenient for the operating personnel to maintain and replace. For example, when replacement or maintenance is needed, the operating personnel can quickly find and replace and maintain. In addition, the lengths of the positive input connecting piece, the third conductive connecting piece, the positive output connecting piece, the negative input connecting piece, and the negative output connecting piece can be reduced to reduce the cost and weight of the charging pile.
[0021] In an optional implementation, the charging pile further includes a detection module. The detection module is arranged on the first plate, and the detection module is electrically connected to the second switch module and the negative output connecting piece, and is configured to detect an output current and an output voltage of the negative output connecting piece. The negative input connecting piece, the second switch module, the detection module, and the negative output connecting piece are sequentially arranged along the first direction, the detection module is connected to the second switch module through a fourth conductive connecting piece, and the detection module is connected to the negative output connecting piece.
[0022] Since the current is transmitted from the positive electrode of the charging gun to the negative electrode of the charging gun, and then transmitted to the detection module by the negative output connecting piece. Therefore, the output current and the output voltage of the negative output connecting piece detected by the detection module, that is, the current value and the voltage value detected by the detection module, are the output current and the output voltage of the charging gun. Through the detection module, the voltage and the current in the circuit for supplying power to the charging gun can be monitored in real time to ensure the normal operation of the circuit. The control module is electrically connected to the detection module, and the control module is configured to control the detection module to detect the output current and the output voltage of the negative output connecting piece.
[0023] Compared with the detection module configured to detect the input current and the input voltage of the positive output connecting piece, for example, the detection module is electrically connected to the first switch module and the positive output connecting piece, and is configured to detect the input current and the input voltage of the positive output connecting piece. If a circuit fault occurs between the positive output connecting piece and the charging gun, the voltage value and the current value detected by the detection module are not the input voltage and the input current of the charging gun. Therefore, the detection module detects the output current and the output voltage of the negative output connecting piece, and the detection precision is higher and the reliability is better.
[0024] In an alternative embodiment, the charging pile further comprises a metering module. The metering module is arranged on the second board and is electrically connected to the detection module through a cable, and is configured to meter the output voltage and output current detected by the detection module. The metering module is located on the side of the first board close to the second conductive connector. The detection module is located on the side of the second board close to the second conductive connector.
[0025] The metering module is configured to meter the output voltage and output current detected by the detection module, so as to monitor the voltage and current in the circuit for supplying power to the charging gun in real time, facilitating the work personnel to check and record. The control module is electrically connected to the metering module, and is configured to control the metering module to meter the output voltage and output current detected by the detection module.
[0026] The metering module is arranged on the second board, i.e., the metering module and the control module are located on the same board. This can facilitate the realization of functional partitioning, avoid the mutual interference between the devices on the first board and the devices on the second board, and improve the reliability of the charging pile.
[0027] In addition, the metering module is located on the side of the first board close to the second conductive connector. The detection module is located on the side of the second board close to the second conductive connector, i.e., the metering module is arranged close to the detection module, which can facilitate the connection of the metering module and the detection module.
[0028] In an alternative embodiment, the switch module comprises an interface, the interface is electrically connected to the control module through a cable, and the interface is arranged on the side wall of the switch module. The switch module comprises a plurality of switch modules, and the plurality of switch modules form two groups. The two groups of switch modules are arranged in a staggered manner along a first direction. Each group of switch modules comprises a plurality of switch modules arranged along a second direction. In each group of switch modules, the interface of the switch module located at the edge of the arrangement direction is opposite to the adjacent switch module. The first direction and the second direction are perpendicular.
[0029] Since the switch module is provided with the interface, the interface is electrically connected to the control module through the cable. When installing and replacing the switch module, the cable needs to be pulled out or plugged in from the interface first. The two groups of switch modules are arranged in a staggered manner along the first direction. In each group of switch modules, the interface of the switch module located at the edge of the arrangement direction is opposite to the adjacent switch module. In this way, the worker can stretch his hand into the switch module and the switch module adjacent to it in the second direction when disassembling the switch module located at the edge of the arrangement direction, which facilitates the worker to plug and pull the cable.
[0030] In some examples, the interface of the switch module located at the middle position of the arrangement direction is opposite to the adjacent switch module. In this way, the worker can stretch his hand into the switch module and the switch module adjacent to it in the second direction when disassembling the switch module located at the middle position of the arrangement direction, so as to facilitate the worker to plug and pull the cable.
[0031] In an alternative embodiment, the switch module includes an input end and an output end, and the input end and the output end are located on the side of the switch module away from the first plate. The input end is connected to the first conductive connecting piece, and the output end is connected to the second conductive connecting piece. The first conductive connecting piece, the input end, the output end, and the second conductive connecting piece are sequentially arranged along the first direction. The charging pile further includes a third plate, and the third plate is located on the first plate. The switch module is fixed to the side of the third plate away from the first plate. The third plate has a locked state and an unlocked state. When the third plate is in the locked state, the switch module is fixed relative to the first plate. When the third plate is in the unlocked state, the third plate can be moved along the second direction to insert or extract the switch module between the first plate and the first conductive connecting piece. The first direction and the second direction are perpendicular.
[0032] The input end and the output end of the switch module are located on the side of the switch module away from the first plate. When disassembling the switch module, the first conductive connecting piece and the second conductive connecting piece need to be disassembled first, and then the switch module needs to be disassembled. The disassembly process is complicated and inconvenient to operate. By moving the third plate along the second direction to insert or extract the switch module between the first plate and the first conductive connecting piece, i.e., the switch module is extracted or inserted between the first plate and the first conductive connecting piece along the second direction. In this way, the first conductive connecting piece and the second conductive connecting piece do not need to be disassembled, and the pile switch module can be disassembled, which is convenient and fast to operate.
[0033] For example, when disassembling the switch module, the connection between the switch module and other devices is first disassembled, and then the third plate is switched to the unlocked state, so that the third plate moves along the second direction to extract the switch module between the first plate and the first conductive connecting piece. Then the operator can disassemble the switch module from the third plate, which is simple and convenient to operate.
[0034] When installing the switch module, the switch module can be installed on the third plate first, and then the third plate is moved along the second direction to insert the switch module between the first plate and the first conductive connecting piece. Then the third plate is switched to the locked state, i.e., the switch module is fixed relative to the first plate, and finally the switch module and other devices are connected.
[0035] In an alternative embodiment, the second plate is located on the side of the first plate away from the switch module. The third plate includes a bent portion, and the bent portion is located at one end of the third plate in the second direction. The bent portion and the second plate are opposite in the second direction. When the third plate is in the locked state, the bent portion is fixed to the second plate.
[0036] The bending part is arranged to fix the third plate to the second plate, that is, the third plate (or the switch module) is fixed relative to the first plate, so that the third plate is in a locked state. When the third plate is in an unlocked state, the bending part can be removed from the second plate to release the fixation between the bending part and the second plate, thereby facilitating the movement of the third plate in the second direction to insert or extract the switch module between the first plate and the first conductive connecting piece.
[0037] In an optional embodiment, the charging pile further comprises a limiting piece. The limiting piece is fixed to the first plate. The limiting piece comprises a first segment and a second segment, and the first segment and the second segment are arranged at an included angle. The first segment, the second segment and the first plate enclose an accommodation space, and an end of the third plate in the first direction is accommodated in the accommodation space. The first segment is capable of abutting against the third plate in the first direction. The second segment is capable of abutting against the third plate in the third direction. The third direction is perpendicular to the first direction and the second direction.
[0038] In this example, the end of the third plate in the first direction is accommodated in the accommodation space, and the first segment is capable of abutting against the third plate in the first direction, that is, the first segment is capable of limiting the movement of the third plate in the first direction in the direction towards the first plate. The second segment is capable of abutting against the third plate in the third direction, that is, the second segment is capable of limiting the movement of the third plate in the third direction in the direction towards the second segment. Therefore, the limiting piece can prevent the movement of the third plate on the first plate in the first direction and the third direction, so as to ensure that the third plate is fixed relative to the first plate, that is, to ensure that the switch module is fixed relative to the first plate.
[0039] In some examples, the limiting piece comprises two, and the end of the third plate in the first direction is accommodated in the accommodation space of one limiting piece and the other end is accommodated in the accommodation space of the other limiting piece. The first segment of each limiting piece abuts against the third plate in the first direction to limit the movement of the third plate in the first direction. The second segment of each limiting piece abuts against the third plate in the third direction to limit the movement of the third plate in the third direction.
[0040] In some examples, the first direction is the length direction of the first plate, the second direction is the width direction of the first plate, and the third direction is the thickness direction of the first plate.
[0041] In an optional embodiment, the charging pile further comprises an auxiliary power supply. The auxiliary power supply is used to supply power to the switch module and the control module. The auxiliary power supply is arranged on the second plate, and the auxiliary power supply is located on the side of the second plate close to the first conductive connecting piece.
[0042] The auxiliary power supply is arranged on the second plate, that is, the auxiliary power supply and the control module are located on the same plate. In this way, it is beneficial to realize functional partitioning, prevent interference between the devices on the first plate and the devices on the second plate, and improve the reliability of the charging pile. In addition, it is also convenient for the auxiliary power supply to be connected with the switch module and the control module.
[0043] In some examples, the auxiliary power supply is connected to the power grid, and cables between the auxiliary power supply and the power grid transmit alternating current, the auxiliary power supply is located on the side of the second plate close to the first conductive connecting piece, preventing the cables of the auxiliary power supply connected to the power grid from short-circuiting or circuit interference with other devices on the support, such as the control module.

Referring to Figure 5 The support 1 includes a first plate 01 and two second plates 02, and the first plate 01 is connected between the two second plates 02. The first plate 01 and the second plate 02 are arranged at an angle. The first plate 01 and the second plate 02 are located in different planes, i.e., the first plate 01 and the second plate 02 form a spatial structure.

Moreover, it is beneficial to realize functional partitioning, avoid the case of mutual interference between the devices on the first plate 01 and the devices on the second plate 02, and improve the reliability of the charging pile 100.
[0080] In addition, the installation and maintenance of the devices on the support 1 can be facilitated. For example, in the case of a small installation space, the devices are first installed on the support 1, and then the support 1 is installed on the inner wall of the charging pile 100, which facilitates the installation of the operating personnel, saves labor time, and improves productivity.
