DETAILED DESCRIPTION

[0023] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0024] like Figures 1 to 4 A waterproof battery box shown in the figure includes a battery shell 1, which serves as the installation base of the battery body 15 and is used to accommodate and protect the lithium battery body 15. A baffle 7 is horizontally installed in the inner cavity of the battery shell 1 to separate the battery shell 1 into a mounting part and a water accumulation part 19. A plurality of leakage holes 21 are opened on the plate surface of the baffle 7. The baffle 7 is used to filter out accidental water accumulation inside the battery shell 1 downward to prevent the internal components from being soaked and damaged due to the accumulated water.

[0025] like Figure 3 As shown, a partition 17 is vertically installed in the inner cavity of the installation part to separate the inner cavity of the installation part into a battery cavity and a functional cavity. The battery main body 15 is installed in the battery cavity, and the controller 18 and the heater 3 are installed in the functional cavity; the partition 17 is used to isolate the battery assembly 15 from the controller 18 to prevent the two from affecting each other. The controller 18 contains a PLC controller, a small battery pack and other equipment, which can be controlled by external signals to control the status of the battery assembly 15 and the heater 3.

[0026] like Figure 2 As shown, the dehumidification component includes a slide groove 2 and a heater 3 provided on an inner wall of the functional cavity. The slide groove 2 is provided with a heater 3 which slides therein. The heater 3 is a heater. The slide groove 2 can slide the heater 3 into the inner cavity of the functional cavity to provide a position for the installation of the heater 3. Starting the heater 3 can help increase the temperature inside the battery casing 1, maintain a dry environment inside the battery casing 1, evaporate the moisture in the humid air, and reduce the impact of moisture on the battery assembly 15 and the circuit.

[0027] A mounting plate is installed on an inner wall of the functional cavity, and a slide groove 2 is opened on the plate surface of the mounting plate. A slider matching the slide groove 2 is installed on the heater 3, and the heater 3 can be lifted up to be conveniently taken out of the slide groove 2 and replaced; a stopper 4 is installed in the slide groove 2 through a fixing bolt 5, and the stopper 4 is located above the slider. The combination of the stopper 4 and the fixing bolt 5 is adopted, and the fixing bolt 5 can fix the stopper 4 on the slide groove 2, which can prevent the battery housing 1 from causing the heater 3 to slip out of the slide groove 2 in a bumpy situation, causing the heater 3 to be damaged by collision.

[0028] A heater cable 6 is installed on the heater 3 , and the heater cable 6 is connected to an external control component. The heater cable 6 is used to connect the heater 3 with the external control component to provide signal and power supply for the heater 3 .

[0029] In summary, the generation of water vapor inside the battery box assembly 1 can be effectively prevented. When the battery body 15 operates in a humid environment, the battery body 15 and the circuit can be effectively prevented from being damp, corroded or damaged, thereby improving the reliability and stability of the equipment.

[0030] like Figure 4 As shown, a one-way valve 20 is installed on one side of the water accumulation portion 19, and the bottom surface of the water accumulation portion 19 is an inclined bottom surface. The lower end of the inclined bottom surface of the water accumulation portion 19 is arranged close to the one-way valve 20, that is to say, the bottom surface of the water accumulation portion 19 is designed to be inclined in the direction of the one-way valve 20, so that the accumulated water filtered by the baffle 17 can be guided through the bottom surface of the water accumulation portion 19 to be discharged from the one-way valve 20. The one-way valve 20 can not only provide a position for the discharge of accumulated water, but also prevent external accumulated water from flowing back into the inner cavity of the battery casing 1 to cause damage to the battery assembly 15.

[0031] like Figure 1 As shown, a housing cover plate 9 is installed on the battery housing 1, the battery housing 1 and one side of the housing cover plate 9 are installed by a hinge, the battery housing 1 and the other end of the housing cover plate 9 are installed by a buckle 10, and a handle 11 is installed on the housing cover plate 9.

[0032] The equipment in the inner cavity of the battery shell 1 can be inspected by opening the shell cover 9. The buckle 10 is used to prevent the shell cover 9 from being opened by accident, and the pressure applied by the shell cover 9 can improve the sealing of the sealing strip between the battery shell 1 and the shell cover 9. The handle 11 can facilitate the staff to lift the battery box for movement.

[0033] In addition, if Figure 3 and Figure 4 As shown, a sealing strip 8 is installed on the top surface of the battery housing 1, and the sealing strip 8 can ensure its sealing when the battery box is closed.

[0034] like Figure 3As shown, a battery cable 16 is installed on the battery body 15, and a power interface 12 is installed on one side of the battery shell 1. The battery cable 16 is connected to the power interface 12. The power interface 12 can connect an external power source or a device that requires electricity to its interior and connect to the battery assembly 15 in the inner cavity of the battery shell 1. The interior of the battery body 1 is used to store or release electricity to ensure the normal power supply of external devices. The other end of the battery cable 16 is connected to the power interface 12, so that the power of the lithium battery body can be transmitted.

[0035] like Figure 3 As shown, a plurality of support blocks 13 are installed on the surrounding walls of the inner cavity of the battery cavity, and the battery body 15 is mounted on the support blocks 13 ; a buffer foam 14 for wrapping the battery body 15 is installed between the support blocks 13 and the battery body 15 .

[0036] A combination of a support block 13 and a buffer foam 14 is used. The support block 13 provides a position for installing the battery assembly 15, and the support block 13 can support the battery assembly 15 to prevent it from contacting the upper surface of the baffle 7, which would cause the battery assembly 15 to be damaged by accumulated water. The buffer foam 14 can provide a buffering effect for the battery component 15.

[0037] By installing a component for preventing the generation of water vapor inside the battery box in the device, when the battery component is operated in a humid environment, the battery component and the circuit can be effectively prevented from moisture, corrosion or damage, thereby improving the reliability and stability of the equipment.
