Description
Technical field
The utility model relates to a kind of battery case for electric automobile.
Background technology
Electric automobile is take on-vehicle battery as power set, utilizes the electricity energy driven vehicle storing in battery to travel, and because electric automobile has environmental protection and energy saving, it is extensively promoted by market.Because the volume and weight of batteries of electric automobile is all very large, be arranged on automobile rear and not only can take interior space, also can make the weight of automobile concentrate on rear portion, affect the stability of automobile.Notification number is that CN202308113U, name are called in the Chinese utility model patent of " a kind of electric automobile flat cell box and electric automobile " and disclose a kind of battery case being arranged on automobile chassis, this battery case comprises the flat box body of uncovered, in box body, be provided with multiple separations location gear, separating the battery that assembles flat between the gear of location.But, because this battery case lacks lid, battery in battery case is directly installed on the opening part of box body, cause battery to be directly exposed to automobile chassis below, this battery case to the protection intensity of battery a little less than, battery is easily subject to the invasion and attack of the impurity such as extraneous rainwater, dust, and this will cause the useful life of harmful effect, shortening battery to battery.
Summary of the invention
The purpose of this utility model is to provide a kind of battery case battery to higher protection intensity.
For achieving the above object, battery case of the present utility model adopts following technical scheme: a kind of battery case, comprise casing, casing comprises box bottom and is around in box bottom sidewall all around around, box bottom and each sidewall surround a cavity with opening, and the opening part of described cavity is provided with and the removable case lid being tightly connected of casing.
The bottom surface that is positioned at cavity on described box bottom is provided with reinforcement.
Described reinforcement is crisscross to be welded on box bottom.
The two ends, left and right of described case lid are distinguished on the sidewall of removable fixed installation left and right by connecting bolt, between described casing and case lid, are provided with seal.
On the sidewall of described left and right, be respectively equipped with for being sleeved on the fairlead on the reference column on automobile chassis.
On the sidewall of described left and right, be respectively equipped with the lifting twist lock for coordinating with the installing hole on automobile chassis.
Described front and back sidewall and box bottom are wholely set and form U-lag structure, and described left and right sidewall is welded on respectively the left and right sides of box bottom.
Described left and right sidewall is the rectangular hollow beam of cross section.
The removable case lid being tightly connected of the utility model setting and casing, cell sealing can be arranged in battery case, case lid can prevent that battery is exposed in outside air, stop extraneous moisture, impurity to enter casing, thereby increased the protection intensity of battery case, used battery case of the present utility model to extend the life of a cell.
Further, can be by the fairlead cover on the sidewall of left and right is installed on the reference column of automobile chassis, thus battery case can be positioned on automobile chassis fast and accurately, the operation that fixedly mounts battery case is more prone to.
Further, the reinforcement arranging on box bottom strengthens the intensity of casing self, thereby increases the bearing capacity of casing, and the battery case that has met large scale span is arranged on the requirement of strength of automobile chassis below.
