[0002] The main power source of battery cars is provided by batteries, which convert electrical energy into kinetic energy. At present, most of the batteries used in battery cars are lead-acid batteries. This kind of battery can be charged and reused repeatedly. However, with the increase of use time and charging times, the battery capacity of lead-acid batteries will gradually decrease. When lead-acid batteries are charged, they will generate a certain amount of heat, or due to the aging of the battery and the circuit, high temperature will be generated at the aging position during charging or discharging, thus causing the electric vehicle to catch fire spontaneously, which will not only cause property losses, but also may cause personal injuries.

[0004] In summary, there are deficiencies in the low temperature control stability and processing effect of the battery, and the battery connection wire is not convenient for quick installation and disassembly. Content of the Utility Model

[0005] The utility model is to overcome the deficiencies in the prior art of low temperature control stability and processing effect of the battery, and the battery connection wire is not convenient for quick installation and disassembly, and provides a temperature-controlled battery connection wire structure for stable monitoring of the battery temperature, convenient installation and quick disassembly processing.

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

[0007] A temperature-controlled battery connection wire structure includes a conductive wire and a signal wire. Both ends of the conductive wire are connected with pole connection shells. Temperature sensors and pole connection pieces are installed in the pole connection shells. An anti-slip structure is provided outside the pole connection shells. The pole connection shells are connected with a dust-proof component. One end of the signal wire is connected to the temperature sensor, and the other end of the signal wire is connected with a terminal.

[0008] The pole connection piece is used to connect with the pole. Both the pole connection shell and the pole connection piece are equipped with pole connection pieces for connecting with the positive pole and the negative pole. Both ends of the conducting wire are connected to the pole connection shell to connect the two pole connection pieces, realizing battery series connection. A temperature sensor is connected inside the pole connection shell. The temperature sensor is connected to the pole connection piece to directly and quickly test and monitor the pole temperature through heat transfer. The signal wire is connected to the stability sensor so that the monitored temperature is transmitted to the wiring terminal through the signal wire. The wiring terminal is externally connected to the controller of the battery car to display and control the pole temperature, preventing the battery temperature from being too high and affecting the use and causing safety problems. The pole connection shell is provided with an anti-slip structure to facilitate the quick and stable installation of the battery conducting wire, and at the same time, to realize the quick disassembly, processing, maintenance and replacement of the battery under abnormal temperature. The pole connection shell is connected with a dust-proof component to prevent liquid and dust from entering, further improving the safety during use. It achieves the effects of stably monitoring and processing the battery temperature, improving the safety of battery use, and enhancing the convenience of installation and disassembly.

[0009] Preferably, one end of the pole connection shell is provided with a mounting hole, a fixed cavity is arranged inside the pole connection shell, and the other end of the pole connection shell is provided with an outlet hole. The mounting hole, the fixed cavity and the outlet hole are connected. One end of the pole connection piece is provided with a connection hole, and the pole connection piece is connected to the mounting hole. The centers of the mounting hole and the connection hole are the same. The other end of the pole connection piece is connected to the temperature sensor, and the conducting wire is clamped to the outlet hole. The pole connection piece is connected at the mounting hole and the fixed cavity of the pole connection shell, and the connection hole of the pole connection piece coincides with the hole of the mounting hole to fix the structure through the pole and the connecting screw. The other end of the pole connection piece is placed in the fixed cavity and connected to the temperature sensor and the end of the conducting wire. The conducting wire extends out of the outlet hole and is tightly connected to the hole wall, fixing the pole connection piece and the conducting wire. It achieves the effects of ensuring the connection stability between the battery connecting wire and the battery, and improving the connection stability of the temperature sensor and the conducting wire.

[0010] Preferably, the pole connection shell is provided with a positioning groove, and the positioning groove is opened on the hole wall of the outlet hole.

[0011] Preferably, the anti-slip structure includes anti-slip platforms, which are depressions on both sides of the end face of the pole connection shell. The anti-slip platforms in the anti-slip structure are depressions on both sides of the end face of the pole connection shell, and the shape of the depression structure is a stepped shape like an L shape, so as to increase the picking-up friction force. At the same time, the anti-slip platforms are placed on one side of the pole connection shell to facilitate positioning the connection position of the pole connection piece in the installation hole (biased at the hole opening). The effects of improving the picking-up convenience, installation positioning and aesthetics of the battery connecting wire are achieved.

[0012] Preferably, the anti-slip structure includes anti-slip grooves. There are several anti-slip grooves, which are depressions on one side of the pole connection shell, and a finger groove guiding surface is provided on the other side of the pole connection shell.

The dust-proof cover is buckled with the installation hole. The connecting strip in the dust-proof component is connected to the end face of the pole connection shell opposite to the conductive wire. At the same time, the dust-proof cover is connected to the connecting strip, so as to buckle the dust-proof cover with the installation hole (the hole opening on the side away from the pole connection piece) through the bending of the connecting strip to protect the installation hole and prevent external dust and sundries from entering. The snap button protrudes from the end face of the dust-proof cover to facilitate pressing the dust-proof cover into the installation hole. The deformation groove cooperates with the fixing screw, and at the same time, the diameter of the snap button is smaller than the diameter of the dust-proof cover to facilitate removing the dust-proof cover by the snap button for disassembly. The effects of improving the installation and disassembly of the battery connecting wire structure and ensuring the dust-proof effect are achieved.

[0014] Preferably, the signal wire is provided with a wire bundling sleeve, and the wire bundling sleeve is sleeved on the signal wire.
