[0002] With the widespread use of automobiles and the great increase in the number of electrical devices on automobiles, the electrical safety of the entire vehicle has received more and more attention. It has become a trend to set up a total fuse box for the power supply battery of the entire vehicle; as the total protection of the power supply of the entire vehicle, the location of the total fuse box is to be as close to the battery as possible, providing protection from the starting point of the power supply of the entire vehicle. At present, the fuse box is generally installed near the terminal or connection point of the battery, rather than directly on the top of the battery cover. During the driving process of the vehicle, it may be affected by vibration, causing the fuse box to loosen or fall off, thereby affecting the normal operation of the circuit.

[0003] At present, the common way to set up the fuse box is to fix the fuse box on the positive pole of the battery. The main problems of this form are:

[0004] 1. The battery positive pole fuse box is hung on the battery positive pole post. The quality, volume and number of fuses in the fuse box should not be too large. When the hanging fuses and the wiring harnesses connected to the fuses are too many and too hard, the installation stability of the battery positive pole fuse box is poor, which will cause the battery positive pole post 3 to be overstressed and there is a risk of damage, which poses a safety hazard.

[0005] 2. Since the battery positive fuse box is suspended next to the battery, it requires a large space in the X and Y directions of the front cabin of the car. Summary of the invention

[0006] The purpose of the utility model is to solve the above-mentioned deficiencies in the prior art, thereby providing a battery cover, a lead-acid battery, and an assembly structure of a lead-acid battery and a fuse box.

[0007] A lead-acid battery and fuse box assembly structure, comprising a battery body and a fuse box body;

[0008] The battery body comprises a battery tank body and a large battery cover buckled on the upper end of the battery tank body;

[0009] The outer wall of the battery cover is provided with a convex edge, and the upper end of the battery cover has two positioning posts, which are arranged alternately front and back;

[0010] The fuse box body has a positive pole mounting hole at one end, and a positioning hole on the fuse box body for cooperating with two positioning posts on the battery cover;

[0011] The outer side wall of the fuse box body extends downwardly with a positioning claw and a clamping claw;

[0012] There are two clamping claws, which are respectively arranged on the left and right sides of the fuse box body, and the two clamping claws are respectively buckled on the left and right sides of the convex edge;

[0013] There are two positioning claws, which are respectively arranged on the front and rear sides of the fuse box body, and the two positioning claws respectively abut against the front and rear sides of the convex edge.

[0014] It also includes a base and a pressure strip, wherein the corresponding end of the base is bent outward to have a flange, and both ends of the flange and the pressure strip are provided with a clearance hole;

[0015] The bottom of the battery body is installed in the base, the middle of the pressure strip is pressed on the battery cover, and the two ends of the pressure strip are bent downward and connected and fixed with the corresponding side flanges through bolts and nuts installed in the corresponding clearance holes.

[0016] The fuse box body is located at the upper end of the pressure strip.

[0017] A support plate is provided between the flange and the side wall of the base.

[0018] The front and rear side walls of the base are provided with a plurality of vertical ribs.

[0019] The distance H1 between the left positioning column and the front side of the battery cover is greater than the distance H2 between the right positioning column and the front side of the battery cover.

[0020] A battery cover comprises a large battery cover, wherein a convex edge is protruded from the outer wall of the large battery cover, and two positioning posts are arranged in a staggered manner front to back, and a distance H between the left positioning post and the front side of the large battery cover is greater than a distance H between the right positioning post and the front side of the large battery cover.

[0021] A lead-acid battery, comprising a battery body;

[0022] The battery body comprises a battery tank body and a large battery cover buckled on the upper end of the battery tank body;

[0023] A convex edge is protruded from the outer side wall of the battery cover, and two positioning posts are arranged in a staggered manner front to back at the upper end of the battery cover.

[0024] The distance H1 between the left positioning column and the front side of the battery cover is greater than the distance H2 between the right positioning column and the front side of the battery cover.

[0025] The utility model has the advantages of simple structure, convenient operation, economy and practicality, and can solve the problem of circuit failure that may be caused by vibration of the fuse box.

[0026] The fuse box of the utility model is installed on the top of the battery, which saves the space in the front cabin in the X and Y directions, can optimize the installation space limitation of the fuse box, and provides convenience for replacing the fuse.

[0027] The assembly method of the utility model can improve the quality, volume and number of fuses in the fuse box, and will not cause the battery positive pole fuse box to have poor installation stability due to too many and too hard hanging fuses and wiring harnesses connected to the fuses, which will cause the battery positive pole to be overstressed and thus present the risk of damage, thereby effectively avoiding safety hazards.

[0028] Providing two staggered positioning posts can avoid reverse installation of the fuse box during assembly, which would require rework and affect assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
