Description
Technical field
The utility model relates to a kind of battery box of electrobus.
Background technology
At present, pure electric coach is due to advantages such as its zero-emissions, progressively promote, in order to increase continual mileage, pure electric coach can only be installed more battery, because battery is heavier, generally battery is divided into some parts, then be contained in respectively in each battery box, and by high tension cord, each battery box connected.Consider that battery is heavier, so each battery box is fixed on passenger-carrying chassis, the center of gravity of car load can not increase like this, improve driving safety, but increase the risk of battery box immersion, on the one hand, the conducting connecting part being connected with the conduction of high tension cord due to battery box is exposed in battery box outside, this just cannot guarantee the water proof of battery box conducting connecting part, occur in the situations such as immersion and run into inclement weather at electrobus, the voltage that multiple battery boxs that are cascaded produce is higher, after immersing water, the conducting connecting part of any one battery box all can there is leaky, passenger's life security is produced dangerous, on the other hand, battery in casing is in the situation that working long hours, produce amount of heat, these heats need to be discharged in time, therefore on battery box, be generally provided with ventilation inlet and exhaust outlet, this just causes the water capacity easily to enter in battery box from ventilation inlet or exhaust outlet, causes the battery in battery box that leaky easily occurs.
Utility model content
The purpose of this utility model is to provide a kind of battery box that reduces the electrobus that self leaky occurs.
The utility model adopts following technical scheme: a kind of battery box of electrobus, comprise casing, the front bulkhead of casing is provided with conducting connecting part, the outer peripheral face of described casing is provided with radiating fin, end wall is provided with the liquid level cavity of vertical extension, the bottom of liquid level cavity is provided with and the outside inlet being communicated with of casing, top is provided with and the outside ventilation mouth being communicated with of casing, the height of inlet is lower than described conducting connecting part, the height of ventilation mouth is not less than described conducting connecting part, in liquid level cavity, be provided with for detection of the level sensor that is entered into the liquid height in liquid level cavity by inlet, on the outer peripheral face of casing, be also arranged with for the wind scooper in radiating fin is located at, between the sidewall of casing and wind scooper sidewall, have gap, the rear port place of wind scooper is provided with exhaust fan.
Described casing is tetragonal body, and described liquid level cavity clips is contained between casing end wall and sidewall.
Described liquid level cavity has four, and four liquid level cavitys are separately positioned on the corner location place of casing.
Described casing front bulkhead is provided with power output control device, this device comprises the control capsule of sealing positioning and plug-in mounting on casing front bulkhead, on control capsule front end face, be fitted with the connection terminal for being connected with the battery conductive in casing, electromagnetic relay for controlling connection terminal and battery conductive break-make is installed in control capsule, and described conducting connecting part is described connection terminal.
Adopt the battery box for electric passenger car of said structure, because the end wall of casing is provided with the liquid level cavity of vertical extension, and the inlet of liquid level cavity is lower than conducting connecting part, ventilation mouth is not less than conducting connecting part, like this when after the outside immersion of casing, can guarantee that water entered smoothly in liquid level cavity before immersion highly arrives conducting connecting part, thereby level sensor can accurately be detected by the immersion height that arrives conducting connecting part, and the conduction that detection signal is fed back to cut off with other series-connected cell casees is connected, reduce the high pressure potential safety hazard causing of leaking electricity, and sheathed wind scooper on the radiating fin arranging on casing outer peripheral face and outer peripheral face is conducive to the box house heat radiation of closed structure, avoids casing to leak and cause internal cell immersion to cause electric leakage, entirety to improve the safety performance of battery box.

The specific embodiment
The embodiment of the battery box of the utility model electrobus: as Figure 1-4, comprise casing 1, casing 1 is tetragonal body, the front bulkhead 11 of casing 1 is provided with power control 3, power control 3 comprises the control capsule 31 of sealing positioning and plug-in mounting on casing front bulkhead 11, on control capsule 31 front end faces, be fitted with the connection terminal 32 for being connected with the battery conductive in casing, electromagnetic relay for controlling connection terminal and battery conductive break-make is installed in control capsule 31, and described connection terminal 32 is the conducting connecting part for connecting with other battery boxs.In outside wall surface corresponding to 1 four sidewalls of casing, be equipped with radiating fin 5, because the dissipating area of radiating fin 5 is large, casing 1, as closed structure, is conducive to its internal heat dissipating; On the outer peripheral face of casing 1, be also arranged with wind scooper 2, wind scooper 2 is the square sleeve structure of a front opening, in the rearward end of wind scooper 2, be embedded with the exhaust fan (not shown) that three left and right are arranged side by side, between corresponding wall box and wind scooper sidewall, all there is gap, like this under the effect of three exhaust fans, the heat of deriving through radiating fin 5 enters behind gap, is discharged by exhaust fan, has improved the radiating effect of battery box.The left and right sides of casing 1 end wall seals respectively the direction liquid level cavity 4 that is installed with vertical extension, each liquid level cavity 4 is tightly connected with the wall box of respective side, each like this liquid level cavity 4 clips are contained between corresponding casing end wall and sidewall, and are distributed in the corner location place of casing; Offer in liquid level cavity 4 bottom surfaces with outside inlet, the top being communicated with of casing and offer and the outside ventilation mouth being communicated with of casing, the height of ventilation mouth is higher than conducting connecting part, when after the outside immersion of casing 1, water is entered in liquid level cavity 4 by inlet, in liquid level cavity 4, be provided with level sensor, can detect like this liquid level entering in liquid level cavity 4, add that the height of inlet is lower than connection terminal, and the height of ventilation mouth is higher than connection terminal, whether height that can direct-detection casing outside liquid by level sensor is dipped into connection terminal 32.
When above-described embodiment is specifically applied on electrobus, in the time that the liquid of battery box outside enters into any one liquid level cavity 4, level sensor in it all can be transferred to detection signal the display instrument on electrobus, in the time that liquid height arrival will be soaked the height of connection terminal 32, electromagnetic relay disconnects the circuit between the battery in connection terminal 32 and battery box, thereby the conduction of cutting off between battery box and the battery box of other series connection is connected, prevent from, because of the high pressure that multiple battery box series connection produce, human body is produced to injury; Meanwhile, the heat producing in battery box enters in the gap between wind scooper 2 and casing after radiating fin 5 is derived, and discharges through the effect of three exhaust fans.
In other embodiments, liquid level cavity also can be arranged in the outside wall surface of casing end wall, if the height of guaranteeing inlet lower than the height of conducting connecting part, ventilation mouth higher than conducting connecting part.
In other embodiments, the quantity of liquid level cavity can be also one, two or three.
