Description

Technical Field

[0001] The utility model relates to the technical field of battery sensors, in particular to an easily detachable battery sensor. Background Art

[0002] The working principle of the battery sensor is to continuously detect the battery voltage through the internal proportional attenuator, collect the voltage across the internal shunt to detect the battery working current, and use the internal semiconductor temperature sensor to detect the battery temperature; by monitoring the battery working status (current, voltage, temperature) information, it can analyze and calculate the battery status (SOC, SOH).

[0003] Existing battery sensors basically use a main body including a housing, a processor and a shunt disposed in the housing, and the shunt is respectively connected to the connecting bridge and the battery clamp by welding. The shunt and the connecting bridge are welded so that the battery sensor cannot be disassembled, and welding is prone to cold welding and corrosion, which will cause the battery sensor to have a short life.

[0004] When the car battery sensor alarms, it is difficult to analyze the real cause of the failure because it is difficult to disassemble. The unstable welding and corrosion of the shunt and the connecting bridge cause the sensor to fail and fail to monitor the working status of the battery, causing the car to alarm or fail to start.

[0009] Furthermore, a ground wire mounting seat is provided on one side of the battery sensor body, and a ground wire connecting column for contacting the copper bracket is installed on the ground wire mounting seat.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the easily detachable battery sensor of the present utility model comprises an integrally injection-molded battery sensor body 1 and a shunt 2, and also comprises a copper bracket 3 detachably connected to the battery sensor body 1 and the shunt 2; the copper bracket 3 comprises a power connection part 3.1 for bridging the shunt 2, and a battery negative electrode clamp 3.2 for connecting the negative electrode column of the battery.

[0024] In this embodiment, the copper bracket 3 is connected to the battery sensor body 1 and the shunt 2 in a detachable manner, which can facilitate rapid disassembly and maintenance when a car battery fails. The current is fixedly conducted through the battery negative electrode clamp 3.2 and the battery negative electrode column. When the power connection part 3.1 is connected, the current can be transmitted to the shunt 2, avoiding the situation where welding is used during the installation process of the traditional shunt 2 and is prone to sweating, thereby improving the service life.

[0025] As an implementation mode, bolt holes are correspondingly opened on the battery sensor body 1, the shunt 2 and the copper bracket 3, and countersunk bolts 4 are installed in the bolt holes. The battery sensor body 1 and the shunt 2 are fixed respectively by two sets of bolts to ensure that the copper bracket 3 is stably connected to the battery sensor body 1 and the shunt 2.

[0026] As an implementation mode, a ground wire mounting seat 1.1 is further provided on one side of the battery sensor body 1, and a ground wire connecting column 5 for contacting the copper bracket 3 is installed on the ground wire mounting seat 1.1, so as to achieve a good grounding effect and effectively protect the safety of the battery sensor.

[0027] Specifically, the grounding connection column 5 includes a columnar joint 5.1 and a square connection block 5.2; the grounding installation seat 1.1 is provided with a positioning hole 1.2 adapted to the columnar joint 5.1; the copper bracket 3 is also provided with a fixing groove 3.3 which is interference-fitted with the square connection block 5.2. The interference fit between the fixing groove 3.3 and the square connection block 5.2 can ensure the reliability of the grounding connection column 5 after assembly, and at the same time facilitate assembly and improve assembly efficiency.

[0028] As an implementation manner, a sensor output socket 6 is also preset on one side of the battery sensor body 1, and the sensor output socket 6 is used to transmit the battery data acquired by the processor of the battery sensor body 1 to the vehicle system.
