Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, the utility model discloses a schematic structure diagram, the utility model provides a solve its technical problem's technical scheme and be: the utility model provides a battery fuse box, includes the box body, and wherein the upper end left side of box body is provided with starter lug 1, and the upper end right side of box body is provided with engine lug 3, is provided with block 2 in the cladding of box body periphery. Wherein, a second-level fuse 4 is arranged in the box body, and the second-level fuse 4 comprises a second-level fuse A end 41 and a second-level fuse B end 42. The starter lug plate 1 is fixedly connected to the box body through the first wiring stud 8, and the tail end of the starter lug plate 1 is electrically connected with a second-level safety A end 41 and a first distribution plate 52. The engine lug 3 is fixedly connected to the box body through the second wiring stud 9, and one end of the engine lug 3 is electrically connected with a second-level safety B end 42 and a second distribution plate 51 through the second wiring stud 9. Wherein the upper end of the first terminal stud 8 is provided with a battery terminal 10.

Preferably, the starter lug 1 and the engine lug 3 are electrically connected by a secondary fuse 4.

Further, the first segment 52 is electrically connected to a second branch 7, wherein the second branch 7 includes a fourth branch 71 and a fifth branch 72, and a branch fuse is disposed in both the fourth branch 71 and the fifth branch 72.

Further, the second segment 51 is electrically connected to the first branch 6, wherein the first branch 6 includes a first branch 61, a second branch 62 and a third branch 63, and branch fuses are disposed in the first branch 61, the second branch 62 and the third branch 63.

Example 1

When the automobile is running, the generator on the engine charges the electric appliances and the storage battery. The generator simultaneously supplies power to the first branch 6 and the second branch 7 via the first connection stud 8 and the second connection stud 9. Since the second branch 7 is mainly used for charging the storage battery, starting the circuit and driving the relevant electric appliance circuit, which are all important circuits, a secondary fuse 4 is added between the second branch and the generator. If the sum of abnormal large current values of all the branches of the second branch 7 is larger than the rated value of the secondary fuse 4, the time reaches the design upper limit value of the fuse, and the secondary fuse 4 is fused. At this point the second branch 7 circuit has been disconnected from the abnormal circuit first branch 6, at which point the battery can continue to power the branches of the second branch 7, and the customer can look up the 4S shop for the cause of the fault. If the generator is abnormal and the charging current is overlarge, the secondary fuse 4 is fused to protect the storage battery and the second branch 7 from normal operation. Also the customer can look into the 4S store for the cause of the failure.

Example 2

The on-gear power on the vehicle is in a non-starting state, and the generator is not powered by the storage battery at the moment. Under the power-on state, if the first branch 6 generates abnormal super-large current, if the sum of the abnormal large current values of all branches of the first branch 6 is larger than the rated value of the second-stage fuse 4, the time reaches the design upper limit value of the fuse, and the second-stage fuse 4 is fused. The second branch 7 circuit and the fault circuit the first branch 6 have now been disconnected. The storage battery can continuously supply power to the branches of the second branch 7, and a customer can find out the fault reason by a limping 4S shop.

It will be apparent to those skilled in the art that changes and modifications may be made to the present invention without departing from the spirit and scope of the embodiments of the invention. Thus, if such modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
