Description

Technical Field

[0001] The utility model relates to the technical field of fire warning, in particular to a fire warning device for a battery vehicle. Background Art

[0002] Battery scooters, also known as "electric vehicles," are purely electric vehicles powered by batteries and driven by electric motors. They have gained widespread popularity in my country in recent years. However, since battery scooters are primarily powered by batteries, they are prone to spontaneous combustion in hot weather, endangering lives and causing property damage.

[0003] The existing prevention method is to install a temperature sensor in the community's elevator to detect electric bicycles entering the elevator and corridor, and place relevant slogans prohibiting flying wires and electric bicycle parking in the community; some communities also set up a reward mechanism for reporting electric bicycles entering residential areas to enhance people's awareness of prevention.

[0004] However, the above-mentioned fire prevention method can only rely on the residents' self-consciousness and cannot take the initiative to provide fire warnings. The prevention effect is poor, and therefore there is room for improvement. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a battery vehicle fire warning device. The advantage of the utility model is that the property loss caused by the battery vehicle fire is greatly reduced.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The battery vehicle fire warning device includes a housing and a face frame, wherein a visual module is embedded in the face frame, and three mounting holes are respectively opened on the back of the housing. A smoke sensor, a non-contact temperature sensor, and an ambient temperature sensor are respectively installed on the inner walls of the three mounting holes. The smoke sensor, the non-contact temperature sensor, and the ambient temperature sensor are all connected to the same microcontroller via signal lines, and the microcontroller is interactively connected to the visual module via the signal line; and further includes a Bluetooth communication module;

[0008] The Bluetooth communication module is interactively connected to the microcontroller via a signal line, and the Bluetooth communication module sends the fire risk level and smoke test results to the APP end in real time.

[0009] The utility model is further configured such that the visual module includes an LCD touch screen, which is embedded in a mounting opening on the surface of the face frame. The configuration of the LCD touch screen facilitates developers to intuitively observe and debug images, thereby providing users with comprehensive protection in terms of stability and reliability.

[0010] The utility model is further configured such that a power supply port is provided on one side of the face frame, and the power supply port is connected to the power supply of the visual module. The setting of the power supply port facilitates power supply to the device and improves the convenience of power supply.

[0011] The present invention further provides that the non-contact temperature sensor is an infrared temperature sensor. This sensor can determine the surface temperature of an object by analyzing the infrared radiation it emits. This method offers high accuracy, rapid response, and excellent stability, and is unaffected by ambient temperature. Compared to contact temperature measurement, infrared temperature measurement has the advantage of not requiring contact with the object being measured, thus preventing interference with the object's temperature field, and also providing a faster response time.

[0012] The present invention is further configured such that the shell and the face frame are fixed via a detachable mechanism.

[0013] The present invention is further configured such that the detachable mechanism includes a limit plug hole provided at the bottom of the shell, and a limit plug block is provided on the surface of the face frame close to the same side of the shell, and the limit plug block is adapted to the limit plug hole;

[0014] The housing is connected to the top of the face frame by fixing bolts. When the device needs to be repaired, the fixing bolts are loosened and the face frame is pulled upward to separate the face frame and the housing, eliminating the need for multiple bolts to fix them, thereby improving the convenience of operation.

[0015] The present invention is further configured such that a groove is provided on the top of the shell, and the fixing bolt is located in the groove. When the fixing bolt is located in the groove, the shell and the face frame can be conveniently connected by the fixing bolt.

[0016] The beneficial effects of the utility model are:

[0017] 1. When the battery vehicle fire warning device is in use, the smoke sensor detects the smoke concentration in the air, the non-contact temperature sensor and the ambient temperature sensor detect the ambient temperature, the microcontroller reads the smoke concentration and temperature respectively, and the Bluetooth communication module sends the fire risk level and smoke test results to the app in real time to achieve efficient remote monitoring and early warning, which can greatly reduce the property loss caused by battery vehicle fire.

[0018] 2. When the battery vehicle fire warning device needs to be repaired, loosen the fixing bolts and then pull the surface frame upwards to separate the surface frame and the outer shell. There is no need to fix it with multiple bolts, which improves the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Reference Figure 1-3 The battery vehicle fire warning device includes a shell 1 and a face frame 2. The face frame 2 is embedded with a visual module 11. The model of the visual module 11 is K210. It can recognize 20 different objects and perform autonomous learning and classification according to similar features. For this project, its appearance is more delicate and compact, which is convenient for installation on other robot equipment and work with other sensors. Three mounting holes are respectively opened on the back of the shell 1. The inner walls of the three mounting holes are respectively installed with a smoke sensor 7, a non-contact temperature sensor 8 and an ambient temperature sensor 5. The model of the non-contact temperature sensor 8 is DFROBOT, the model of the smoke sensor 7 is MQ2, and the model of the ambient temperature sensor 5 is DS18B20.

The model of the microcontroller is ESP32. The microcontroller is interactively connected with the visual module 11 through signal lines. It also includes a Bluetooth communication module, model HC-08.

[0027] The Bluetooth communication module is interactively connected to the microcontroller through a signal line, and the Bluetooth communication module sends the fire risk level and smoke test results to the APP in real time.

[0028] In this embodiment, the visual module 11 includes an LCD touch screen 3, which is embedded in the mounting opening on the surface of the face frame 2.

The top of the housing 1 has a groove 6, and the fixing bolt 9 is located within the groove 6. When the fixing bolt 9 is located within the groove 6, the housing 1 and the face frame 2 can be easily connected by the fixing bolts 9.
