Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery swapping technology, and more specifically, to an electric vehicle battery swapping safety detection and integrated alarm device. Background Technology

[0002] With the rapid development of the electric vehicle industry, battery swapping has been widely used due to its high energy replenishment efficiency.

[0003] However, existing electric vehicle battery swapping processes have certain shortcomings. First, during battery replacement, the environmental monitoring of the battery compartment is limited to a single dimension. Traditional solutions often only include temperature sensors, which cannot detect electrolyte leaks (abnormal VOCs) or early fires (smoke) in a timely manner. Second, emergency power outages rely on manual operation, making it impossible to unplug the power cord promptly. Therefore, we have made improvements by proposing an electric vehicle battery swapping safety detection and integrated alarm device. Utility Model Content

[0004] The purpose of this utility model is to address the current design of electric vehicle battery swapping safety detection and integrated alarm devices, which can solve the problems of single-dimensional environmental monitoring of the battery compartment during battery replacement, traditional solutions mostly only configure temperature sensors, which cannot detect electrolyte leakage (abnormal VOC) or early fire (smoke) in time; secondly, emergency power cut-off relies on manual operation, which cannot unplug the power supply plug in time.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] Electric vehicle battery swapping safety testing and integrated alarm device to improve the above problems.

[0007] The application is as follows:

[0008] The electric vehicle battery swapping safety detection and integrated alarm device includes an electric vehicle seat bucket, which contains a battery pack and a power supply line.

[0009] The detection alarm component includes a temperature sensor, a VOC sensor, and a smoke detector fixed to the inner wall of the electric vehicle seat bucket; a speaker hole at the top of the electric vehicle seat bucket; an inner cavity at the bottom of the electric vehicle seat bucket; a speaker installed inside the inner cavity; a power supply module and a control circuit board; a cover plate at the bottom of the inner cavity; a connecting plate on the outside of the plug; an electric telescopic rod installed at the top of the connecting plate; an abutment block connected to the output end of the electric telescopic rod; and a guide rod at the top of the abutment block.

[0010] As a preferred technical solution of this application, the electric vehicle seat bucket and the battery pack are compatible, and the electric vehicle seat bucket is located in the middle of the electric vehicle.

[0011] As a preferred technical solution of this application, a handle is provided on the outside of the battery pack, and a charging interface and a power supply interface are provided on the top of the battery pack.

[0012] As a preferred technical solution of this application, the power supply line is electrically connected to the electric vehicle controller, the power supply line is electrically connected to the plug, and the plug is compatible with the power supply interface.

[0013] As a preferred technical solution of this application, the speaker hole is connected to the inner cavity, the temperature sensor, VOC sensor and smoke detector are all electrically connected to the control circuit board, and the cover plate is compatible with the inner cavity.

[0014] As a preferred technical solution of this application, there are two sets of connecting plates that are symmetrically distributed. The connecting plates and the plug are an integral structure. The number of electric telescopic rods is equal to the number of connecting plates. The output end of the electric telescopic rod is fixedly connected to the contact block. A guide hole adapted to the guide rod is opened in the middle of the connecting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] By configuring the alarm components, when the plug is inserted into the power supply interface, the battery pack's voltage can be checked via the power supply line connected to an external controller. If the voltage is not within acceptable limits, the speaker will sound an alarm through the speaker hole. Simultaneously, the output ends of two sets of electric telescopic rods will drive the contact blocks to press against the top of the battery pack, pulling the plug out of the power supply interface and cutting off the power supply in a timely manner. At the same time, temperature sensors, VOC sensors, and smoke detectors will monitor the environment around the battery pack in real time. If any of these sensors detects a safety hazard, the above steps will trigger an alarm and the plug will be pulled out, thereby improving safety. Attached Figure Description
