[0043] Working principle:

[0044] In the actual creation process of the present invention, in order to avoid the following defects existing in the prior art: "The battery compartment of the electric vehicle in the prior art is the main part where the battery is embedded and installed. However, the battery compartment in the prior art is mainly a sealed structure, which lacks corresponding countermeasures under high temperature and strong earthquake environment, and thus easily causes the battery to spontaneously combust in the compartment, thereby affecting the safety of the entire vehicle." Therefore, an anti-spontaneous combustion cooling component 2, an Internet of Things scanning component 3 and an anti-collision component 4 are specifically proposed.

[0045] As a modified battery compartment 5, this device uses the entire cabin structure, but sets a battery slot 6 between the batteries to avoid the risk of collision and friction between adjacent batteries due to the close distance. We set a heat sink 7 on a part of the battery slot 6; the top of the heat sink 7 achieves liquid cooling and heat dissipation through the heat sink 9 and the compressor 15. The cooled cold liquid will generate cold air inside the wind hood 11. Under the control of the motor 19, the blades 14 rotate at high speed, thereby achieving the effect of cold air output. The cold air is output from the air holes 22 on the cover plate 20, which can achieve the effect of air circulation and cooling inside the battery compartment 5.

[0046] This device also uses and accesses the Internet of Things technology. Its main principle is to use the Internet of Things wireless signal control technology to upload the scanning information of the physical state of the battery in real time, and after system analysis and processing, send the signal to the signal receiver 30 of the anti-spontaneous combustion cooling component 2, thereby realizing the startup of the anti-spontaneous combustion cooling component 2. Therefore, the anti-spontaneous combustion cooling component 2 can achieve the effect of intelligent control. Its working principle is as follows:

[0047] We set up slide grooves 27 on both sides of the battery compartment 5. The slide grooves 27 are the guide sliding parts of the slide 24. A telescopic cylinder 23 for moving the slide 24 is set on one side inside the battery compartment 5. The telescopic cylinder 23 can control the slide 24 to move back and forth inside the battery compartment 5 to perform scanning actions. The scanner 25 set at the bottom of the slide 24 can scan the physical state of the battery inside the battery slot 6. The scanned battery physical data (including temperature, appearance state) and other information will be uploaded to the terminal through the Internet of Things signal transmitter 26. The Internet of Things terminal will analyze the received information and output the signal to the signal receiver 30. The signal receiver 30 will transmit the operating action to the compressor 15 and the motor 19 respectively, so as to achieve the direct control effect of the anti-spontaneous combustion cooling component 2. The Internet of Things control technology connected to this device increases the intelligent anti-spontaneous combustion effect of this device.

[0048] Of course, the battery of the tram may still vibrate under actual working conditions. This vibration may cause damage to the battery, so we also set up an anti-collision component 4; the anti-collision component 4 is an improvement on the traditional installation structure. A hydraulic buffer 34 is set between the bottom plate 33 and the flange 35. The buffer structure can buffer the vibration when the tram is running, thereby avoiding the problem of excessive vibration of the battery causing damage to the battery. The battery may be damaged and spontaneously combust when it collides and rubs against each other.

[0049] The batteries are installed separately through the grid-type battery slots 6, avoiding the problem of mutual frictional charging caused by adjacent installation of the batteries. In addition, such an arrangement ensures that even if a battery in a certain part is damaged, the adjacent batteries will not be damaged due to leakage.

[0050] The battery pack of the device is connected to the power supply by external pin connection, that is, the cathode slot 31 and the anode slot 32 are connected to the power supply. This connection method avoids the complexity of the circuit caused by the internal circuit line, which affects the heat dissipation effect.

[0051] The device also has a voltage stabilizer 36 installed on the circuit board of the circuit to stabilize the voltage output of the circuit and avoid the problem of battery overload caused by excessive voltage fluctuation.

[0052] The grille-type heat sink 7 can increase the heat dissipation effect of the heat sink 9, thereby allowing the coolant inside the compressor 15 to be quickly cooled in a short time, thereby achieving a rapid response effect in the overheating and cooling process of the battery pack.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

Any technician familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacement or change, which should be covered within the protection scope of the present invention.
