Abstract
The utility model discloses a battery box for an electric motor coach. The battery box comprises a box body, wherein an air inlet is formed in the side wall of the box body, wherein liquid level cavities extending vertically are formed in the side wall of the box body; a liquid inlet is formed in the bottom of each liquid level cavity, and a ventilated opening communicated with the outer part of the box body is formed in the upper part of each liquid level cavity; the height of each liquid inlet is lower than that of the air inlet; the height of each ventilated opening is not lower than that of the air inlet; liquid level sensors for detecting the height of liquid entering the liquid level cavities from the liquid inlet are arranged inside the liquid level cavities. When the outer part of the box body is soaked with water, the situation that before the soaking height of water imminently reaching the air inlet, water can smoothly enter the liquid level cavities, is ensured, so that the liquid level sensors can accurately detect out the soaking height of water reaching the air inlet, and feed a detected signal back to cut off the electrical connection of the battery box with other tandem battery boxes.
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, mainly because the battery box of multiple series connection forms a high voltage circuit, and battery box needs for the battery in it dispels the heat, on battery box, be provided with ventilation inlet and exhaust outlet (ventilation inlet is generally lower than exhaust outlet), once water enters into battery box inside from ventilation inlet, will cause battery generation leaky, passenger's life security be produced dangerous.
Utility model content
The purpose of this utility model is to provide a kind of battery box for electric passenger car, and in order to solve existing battery box after the immersion of inside, the high voltage circuit that causes the battery box of connecting with other to form leaks electricity and causes the problem of potential safety hazard.
The utility model adopts following technical scheme: a kind of battery box for electric passenger car, comprise casing, the sidewall of casing is provided with ventilation inlet, on the sidewall of described casing, be also provided with the liquid level cavity of vertical extension, the bottom of liquid level cavity is provided with outside inlet, the top being communicated with of casing and is provided with and the outside ventilation mouth being communicated with of casing, the height of inlet is lower than described ventilation inlet, the height of ventilation mouth is not less than described ventilation inlet, is provided with for detection of the level sensor that is entered into the liquid height in liquid level cavity by inlet in liquid level cavity.
Described liquid level cavity is arranged in casing, and described inlet runs through bottom half, and described ventilation mouth runs through wall box.
Described casing is tetragonal body, and described liquid level cavity has four, and four liquid level cavitys are separately positioned on the corner location place of casing.
On the sidewall of described casing, be also 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 the height of connection terminal is higher than described ventilation inlet.
Adopt the battery box for electric passenger car of said structure, because the sidewall of casing is provided with the liquid level cavity of vertical extension, and the inlet of liquid level cavity lower than ventilation inlet, ventilation mouth higher than ventilation inlet, like this when after the outside immersion of casing, can guarantee that water entered smoothly in liquid level cavity before immersion highly arrives ventilation inlet, thereby level sensor can accurately be detected by the immersion height that arrives ventilation inlet, and the conduction that detection signal is fed back to cut off between other series-connected cell casees is connected.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model.
Detailed description of the invention
The embodiment of the utility model battery box for electric passenger car: as shown in Figure 1, comprise casing 1, casing 1 is tetragonal body, one of them sidewall of casing 1 is provided with ventilation inlet 5 and power control, power control comprises the control capsule 4 of sealing positioning and plug-in mounting on wall box, on control capsule 4 front end faces, be fitted with the connection terminal 6 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 4, the height of connection terminal 6 is higher than ventilation inlet 5, the wall box relative with ventilation inlet 5 is provided with exhaust outlet 2, the height of exhaust outlet 2 is higher than ventilation inlet 5, in casing 1, be positioned at corner location place that sidewall is corresponding and be respectively equipped with a vertical square liquid level cavity 3 extending, the bottom of liquid level cavity 3 and bottom half close contact, one of them sidewall be corresponding sidewall close contact with casing.Offer in liquid level cavity 3 bottoms the inlet that runs through bottom half, on the sidewall contacting with casing, offer the ventilation mouth that runs through the corresponding sidewall of casing, the height of ventilation mouth is higher than ventilation inlet 5, when after the outside immersion of casing 1, water is entered in liquid level cavity 3 by inlet, in liquid level cavity 3, be provided with level sensor, can detect like this liquid level entering in liquid level cavity 3, add that the height of inlet is lower than ventilation inlet 5, and the height of ventilation mouth is higher than ventilation inlet 5, whether height that can direct-detection casing outside liquid by level sensor is dipped into ventilation inlet.
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 3, 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 ventilation inlet 5, electromagnetic relay disconnects the circuit between the battery in connection terminal 6 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.
In other embodiments, liquid level cavity also can be arranged in the outside wall surface of wall box, and inlet and ventilation mouth need not run through casing like this, if the height of guaranteeing inlet lower than the height of ventilation inlet, ventilation mouth higher than ventilation inlet.
In other embodiments, the quantity of liquid level cavity can be also one, two or three.
