Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, specifically to a power swapping connector with power metering function. Background Technology
[0002] Existing battery swapping applications mainly fall into two categories: one is closed-loop battery swapping within industrial parks, where no pricing is involved. These are primarily operated independently by the parks and serve only as supplementary energy replenishment for swapping vehicles, not as a profit-generating measure. The other is commercial battery swapping stations with pricing, requiring precise electricity metering as the basis for charging. Current technology struggles to achieve precise metering of electric vehicle battery charging and discharging in the fast-swapping field, resulting in a lack of accurate data sources for battery swapping operating costs and pricing standards, severely impacting the industry's development.
[0003] Due to structural reasons, existing electricity meters are all located outside the connector and are connected to the connector in parallel via lines. Due to physical characteristics, electromagnetic shielding and insulation considerations, the existing electricity meter structure design is bulky, which is not conducive to the use of connectors. Utility Model Content
[0004] The purpose of this invention is to design an embedded meter connector that embeds the meter into the connector housing, replacing the existing connector mounting plate with the meter's socket and hole contact structure. This allows the meter and connector to be integrated into one unit without the need for additional wiring, thus enabling the acquisition of voltage and current signals.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A battery swapping connector with power metering function includes a floating frame and an electrical component disposed within the floating frame. The electrical component includes a power meter and a connector. The power meter is sealed inside the electrical component, and the signal acquisition channel of the power meter is in contact with the connector.
[0007] In the above technical solution, the electrical components, from the outside to the inside, are a metal housing, an insulator, a meter, and a connector. The connector passes through the meter and the insulator, and the meter is encapsulated in the insulator.
[0008] In the above technical solution, the measuring device includes a circuit board, on which a first channel and a second channel are provided. The first channel and the second channel are used for voltage sampling and current sampling, respectively, and are penetrated by connectors.
[0009] In the above technical solution, a plurality of springs are provided in the first channel, and the springs are used to contact the connector. An annular magnetic flux valve sensor is provided in the second channel.
[0010] In the above technical solution, the floating frame includes a base, a guide shaft disposed on the base, and a floating plate passing through the guide shaft. The floating plate is connected to the base by a compression spring, and the electrical components are disposed inside the floating plate and connected to the floating plate by a tension spring.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0012] The technical solution of this application can meet the current market demand for the metering of charging connectors, and solves the defects of large size and inaccurate measurement of the meter by integrated packaging;
[0013] The metal housing of the connector serves as the shielding layer for the measuring device, and the measuring device is sealed with an insulator to provide electromagnetic shielding protection for the measuring device in the high-voltage range, thus meeting national standard requirements.

Detailed Implementation
[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0022] like Figure 1As shown, the connector in this embodiment adopts a floating connection structure, including a floating frame 1, and an electrical component 2 connected inside the floating frame 1, so that the electrical component 2 has the function of floating and calibrating position during the connection process.
[0023] like Figure 2 As shown, the floating frame 1 includes a base 1-1, a guide shaft 1-5 disposed within the base 1-1, and a floating plate 1-2 disposed above the guide shaft 1-5. The guide shaft 1-5 passes through the floating plate 1-2, allowing the floating plate 1-2 to slide along the guide shaft 1-5. A compression spring 1-4 connects the floating plate 1-2 and the base 1-1, enabling the floating plate 1-2 to reciprocate along the guide shaft 1-5 under the action of the compression spring 1-4. Several tension springs 1-3 are also disposed on the floating plate 1-2, with one end of each tension spring 1-3 connected to an electrical component 2, thereby enabling the electrical component 2 to achieve multi-dimensional floating within the floating frame 1.
[0024] like Figure 3 As shown, the electrical component 2 differs from the traditional connector in that it uses a meter 2-3 instead of the original mounting plate, allowing the pins or sockets to be directly mounted on the meter 2-3. Specifically, from the outside to the inside, it includes a metal housing 2-1, an insulator 2-2, and a relay 2-3. The pins or sockets pass through the insulator 2-2 and connect to the meter 2-3.
[0025] like Figure 4 As shown, the measuring device 2-3 includes a packaged circuit board 3. The packaged circuit board 3 has a first through hole 3-1 and a second through hole. Several spring contacts 3-2 are arranged on the inner wall of the first through hole. When a pin or socket passes through the first through hole, the spring contacts 3-2 fix the pin or socket inside the first through hole. The spring contacts 3-2 are connected to the circuit inside the measuring device 2-3, enabling the acquisition of voltage signals from the pin or socket. An annular flux valve sensor 3-2 is arranged on the second through hole. When a pin or socket passes through the annular flux valve sensor 3-2, the circuit uses the annular flux valve sensor 3-2 to acquire current signals from the pin or socket.
[0026] In this embodiment, the meter 2-3 is integrally encapsulated within the insulator 2-2 using a holistic design. Insulating sealing material is used to seal the points where the meter passes through the pins or sockets, ensuring the insulation and sealing effect of the meter 2-3. The metal housing 2-1 of the connector itself acts as a shielding layer for the meter 2-3, achieving electromagnetic shielding protection in high-voltage environments and ensuring measurement accuracy. This allows the connector to complete measurement while charging.
[0027] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
