Background

With the continuous development of the automobile industry, new energy automobiles have more and more shares in the automobile field. The existing new energy automobile, especially the pure electric vehicle, often has a comparatively bulky battery pack, and the battery pack is generally formed by combining a plurality of modularized batteries in a battery box. However, the existing battery box generally adopts a metal structure, has heavier mass and is not in line with the trend of energy conservation. Meanwhile, the battery box with the metal structure also has the problem of poor insulation effect, and once the battery leaks electricity, the battery box is extremely easy to damage a vehicle-mounted electronic system, so that harm is brought to drivers. In addition, the integration of the existing battery box is poor, the internal battery packs are connected through wires, and the short circuit among the multiple strands of wires in the battery box is easily caused, so that the ignition of the battery is caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a new forms of energy car battery box of PBT material has higher integrated level, reduces the used wire of internal battery, can also effectually alleviate the quality of battery case and promote the insulating effect of battery case simultaneously.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a new energy vehicle battery box made of PBT materials comprises a lower box body and an upper box body made of PBT materials; the lower box body comprises a battery storage part and a plug storage part; the bottom surface of the battery storage part is respectively provided with a first partition strip which is uniformly distributed transversely and a second partition strip which is uniformly distributed longitudinally, conductive copper sheets are embedded in the first partition strip and the battery storage part, two ends of each conductive copper sheet extend out of the plug storage part to be communicated with a plug in the plug storage part of a plug-in unit, and the first partition strip is provided with a socket so that the battery can be communicated with the conductive copper sheets.

Furthermore, the opposite side walls of the plug storage part are symmetrically provided with male buckles matched with the plug.

Furthermore, support bars are evenly distributed in the upper box body, and after the upper box body and the lower box body are covered, the support bars are pressed on the upper surface of the battery.

Furthermore, the supporting bars are provided with a plurality of ventilation holes.

Furthermore, one side of the upper box body and one side of the lower box body are hinged, and the other side opposite to the upper box body and the lower box body is provided with a buckle connecting component.

Furthermore, four fixing lug seats are uniformly distributed on the outer side wall of the lower box body.

Has the advantages that: the PBT material has insulating nature good, high temperature resistant, and density is compared in the metal low a bit, consequently, adopts the preparation of PBT material the utility model discloses, can be more light than conventional metal material's battery case, it is more safe. Simultaneously, the electrically conductive copper sheet has been buried underground in the lateral wall of first parting bead, lower box body to realized with partial circuit integration in the inside effect of battery case, effectually reduced the utility model discloses well a plurality of batteries connect required exposed wire each other, and then reduced the probability of contact short circuit each other between the wire. 2. Set up the pin thread on the lateral wall of plug storage portion for the plug can place the condition that appears becoming flexible with the pin thread lock when placing in plug storage portion. 3. The support bar can compress tightly the battery, prevents that it from jolting and appearing becoming flexible because the car goes in-process, leads to the contact failure of battery, and then influences the normal driving of car. 4. The vent holes are formed in the supporting bars, so that heat emitted by the batteries can be uniformly dispersed in the upper cover, and the natural phenomenon that individual batteries are overheated is avoided. 5. The upper and lower box body hinge and realize the lock through buckle coupling assembling for upper and lower box cover can be by convenient opening, thereby makes things convenient for the staff to the maintenance of inside battery. 6. The ear seat can be convenient the utility model discloses and the fixed mounting between the car.
