Abstract
Description
[Technical Field]
[0001] The present invention relates to a battery exhaust hose connector structure and an on-vehicle battery device structure. [Background technology]
[0002] Some batteries mounted on vehicles are equipped with an exhaust hose that releases gas generated during charging and discharging to the outside (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-96784 Summary of the Invention [Problem to be solved by the invention]
[0004] However, there have been cases where battery fluid stored inside the battery flows into the exhaust hose while the vehicle is running, causing the battery fluid to leak out.
[0005] Therefore, an object of the present disclosure is to suppress the leakage of battery fluid. [Means for solving the problem]
[0006] The battery exhaust hose connector of the present disclosure is a battery exhaust hose connector that connects a battery that stores battery fluid inside to an exhaust hose that exhausts gas generated inside the battery, and is characterized by comprising a hollow L-shaped main body having a hose side end and a battery side end, and a top cover attached to the hose side end of the main body, the top cover communicating with a hose connection port to which the exhaust hose is connected and comprising a tubular portion that protrudes into the internal space of the main body, and the main body comprising an inclined portion that slopes so that the depth from the hose side end becomes deeper the closer it is to the battery side end.
[0007] This prevents battery fluid from flowing from the battery into the main body due to acceleration or vibration while the vehicle is running, as the battery fluid hits the cylindrical portion and leaks out of the hose connection port. Furthermore, the battery fluid that flows into the main body from the battery flows along the inclined portion to the battery, allowing the battery fluid to be returned to the battery. In this way, the battery exhaust hose connector of the present disclosure can prevent battery fluid from leaking out.
[0008] In the battery exhaust hose connector of the present disclosure, the internal space of the main body may have a volume that can store the battery fluid that flows in from the battery and separate the gas that flows in from the battery from the battery fluid.
[0009] This allows the battery fluid that has flowed into the main body to be stored in the internal space of the main body, preventing the battery fluid from leaking out. Also, if gas flows into the main body along with the battery fluid from the battery, the gas can be separated from the battery fluid and only the gas can be discharged to the outside.
[0010] The vehicle-mounted battery device of the present disclosure is an vehicle-mounted battery device comprising: a battery that stores battery fluid inside and is mounted on a vehicle; an exhaust hose that exhausts gas generated inside the battery; and a connector that connects the battery and the exhaust hose, wherein the connector is hollow and L-shaped with a hose side end and a battery side end, and comprises a main body that is attached to the battery so that the battery side end is horizontal and the hose side end faces upward, and a top cover that is attached to the hose side end of the main body, wherein the top cover communicates with a hose connection port to which the exhaust hose is connected and has a tubular portion that protrudes downward into the internal space of the main body, and the main body has a bottom surface that slopes downward as it approaches the battery side end.
[0011] This allows the battery device of the present disclosure to suppress leakage of battery fluid.
[0012] In the vehicle-mounted battery device of the present disclosure, the internal space of the main body may store the battery fluid when the battery fluid flows in from the battery, and may separate the gas from the battery fluid when the gas flows in from the battery, and may discharge the gas from the hose connection port to the exhaust hose.
[0013] As a result, the battery device of the present disclosure can effectively prevent battery fluid from leaking. [Effects of the Invention]
[0014] The present disclosure can suppress the leakage of battery fluid. [Brief explanation of the drawings]

FIG. [Figure 4] 10 is an explanatory diagram showing a state in which battery fluid that has flowed into a connector of the vehicle-mounted battery device of the embodiment flows out toward the battery. FIG. DETAILED DESCRIPTION OF THE INVENTION
[0016] Hereinafter, an embodiment of an in-vehicle battery device 100 will be described with reference to the drawings. As shown in Fig. 1, the in-vehicle battery device 100 includes a battery 10, an exhaust hose 20, and a connector 50. The connector 50 is a battery exhaust hose connector.
[0017] The battery 10 is mounted on a vehicle (not shown). The battery 10 stores battery fluid therein and supplies electric power to the vehicle's accessories and the like.
[0018] The connector 50 is composed of a main body 30 and an upper cover 40. The main body 30 is a hollow L-shaped member with a hose end 31 and a battery end 33, and has an internal space 35. A battery connection port 34 is formed at the battery end 33 of the main body 30, which is connected to the battery 10. The battery connection port 34 is connected to the battery 10 horizontally. When the battery connection port 34 is connected to the battery horizontally, the hose end 31 is positioned upward. In this manner, the main body 30 is attached to the battery 10 so that the battery end 33 is horizontal and the hose end 31 faces upward. The bottom surface 36 of the main body 30 slopes downward toward the battery end 33. The bottom surface 36 also has an inclined portion that slopes so that the depth from the hose end 31 increases toward the battery end 33.
[0019] The top lid 40 includes a lid body 41, a flange 42, a hose connection port 43, and a tubular portion 45. The lid body 41 is a plate member that covers the hose side end 31 of the main body 30. The flange 42 extends from the periphery of the lid body 41 toward the main body 30 and fits into the outer surface of the upper part 32 of the main body 30. The flange 42 and the outer surface of the upper part 32 of the main body 30 are watertight sealed with an O-ring 37. The hose connection port 43 is a tubular member that extends upward from the top surface of the lid body 41. The exhaust hose 20 fits into the outer surface of the hose connection port 43. The tubular portion 45 is a tubular member that communicates with the hose connection port 43 and protrudes downward toward the internal space 35 of the main body 30.
[0020] In the vehicle-mounted battery device 100 configured as described above, gas generated during charging or discharging of the battery 10 passes through the connector 50 and is discharged to the outside from the exhaust hose 20.
[0021] Next, referring to Figures 2 to 4, we will explain the flow of battery fluid when the battery fluid stored inside the battery 10 flows into the internal space 35 from the battery side end 33 of the connector 50 while the vehicle equipped with the in-vehicle battery device 100 is running.
[0022] As shown by arrow 91 in Figure 2, if battery fluid flows forcefully into internal space 35 due to acceleration or the like while the vehicle is running, the battery fluid rises toward upper lid 40 along the inner wall of main body 30 that is farther from battery 10. The battery fluid is then bounced off the underside of lid 41 and falls into internal space 35 of main body 30. At this time, because cylindrical portion 45 is provided on the underside of lid 41, the battery fluid that bounces off the underside of lid 41 can be prevented from flowing into hose connection port 43. This prevents the battery fluid from being discharged to the outside through exhaust hose 20, even if the battery fluid flows forcefully into connector 50.
[0023] Furthermore, when a certain amount of battery fluid flows into the internal space 35 of the connector 50, the battery fluid is stored in the internal space 35 of the main body 30, as shown in Fig. 3. Here, the internal space 35 has a volume that allows the gas that flows in from the battery 10 to be separated from the battery fluid. Therefore, as shown by the white circles in Fig. 3, the gas generated from the battery 10 is separated from the battery fluid in the internal space 35, and only the gas is discharged to the outside through the exhaust hose 20. This makes it possible to prevent the battery fluid from leaking out to the outside through the exhaust hose 20.
[0024] 3, the battery fluid stored in the internal space 35 of the connector 50 flows into the battery 10, or, when there is no gas discharged from the battery 10, returns to the battery 10 as shown by arrow 93 in FIG. 4. At this time, the battery fluid flows along the slope of the bottom surface 36 of the internal space 35 to the battery-side end 33, and returns from the battery-side end 33 to the inside of the battery 10.
[0025] As described above, the in-vehicle battery device 100 can prevent battery fluid from leaking out while the vehicle is running. [Explanation of symbols]
