Example Embodiment

[0017] Example one:

[0018] Such as figure 1 , figure 2 As shown, a battery middle cover structure includes a body 1 with a plurality of vent holes 11 at the top. The body 1 is provided with a positive terminal groove 12 and a negative terminal groove 13, the positive terminal groove 12 and the negative terminal Each slot 13 is provided with a pole hole 14, the positive terminal slot 12 and the negative terminal slot 13 are each provided with at least one positioning boss 15, the bottom end of the body 1 is provided with a groove 2, the body 1 A cavity 3 is provided at the top end of the cavity 3, a number of connecting posts 4 are arranged in the cavity 3, and the bottom end of the connecting post 4 passes through the cavity 3, and the bottom end is flush with the bottom end of the body 1, and two adjacent At least one opening 5 is provided in the cavity 3 between the connecting posts 4, and at least one end of each opening 5 is provided with a bridge hole 6 that is convenient...

Example Embodiment

[0019] Embodiment two:

[0020] As for the battery middle cover structure described in the first embodiment, this embodiment has the following differences: image 3 , Figure 4 As shown, the six exhaust holes 11 are uniformly and symmetrically distributed on the main body 1 in two rows and three rows. Both ends of each opening 5 in the vertical direction are provided with a bridge hole 6, and the openings in the horizontal direction There is a bridge hole 6 on 5, which can adapt to a battery with a current of 12V12A, and the connection is reliable, which ensures the stable performance of the battery and is safe and reliable.

[0021] When in use, the positive and negative terminals are fixedly connected in the positive terminal groove 12 and the negative terminal groove 13 respectively through the positioning boss 15, so that the positive and negative terminals are built in the positive terminal groove 12 and the negative terminal groove 13 to ensure that the battery is placed Whe...

Abstract

The invention relates to a middle cover structure of a storage battery. The middle cover structure comprises a body, wherein a plurality of vent holes are formed in the top of the body, the body is provided with a positive terminal slot and a negative terminal slot, the interiors of the positive terminal slot and the negative terminal slot are respectively provided with a pole hole and at least one locating boss, the body is provided with a nameplate and a mounting slot for mounting the nameplate, and the top of the nameplate is lower than the top of the body. The middle cover structure of the storage battery has the advantages that a positive terminal and a negative terminal are internally arranged in the body through the pole holes in the positive terminal slot and the negative terminal slot, and terminals are fixed in the positive terminal slot and the negative terminal slot through the locating bosses, so that the swinging of the terminals is effectively reduced, the connection is reliable, and a situation of battery short circuit caused by misoperation is avoided; the arrangement of the nameplate facilitates the observation of operators, the safety performance is improved, the use effect is good, the structure is simple, the damage of the nameplate on the storage battery is reduced, and the situation of short circuit due to battery leakage is reduced.

Description

technical field [0001] The invention relates to a battery middle cover structure. Background technique [0002] The storage battery is a device that directly converts chemical energy into electrical energy. With the rapid popularization of electric vehicles, the battery industry has developed rapidly. Usually, in order to facilitate the welding of connecting wires, the terminals are generally higher than the cover surface, but the positive side of the cover surface The negative terminals are very close, and it is easy to short-circuit the battery due to improper operation, which is dangerous. Moreover, the batteries are usually stacked together in the battery box of the electric vehicle, and the two positive and negative terminals often wear the bottom of the stacked battery. , resulting in the phenomenon of battery leakage and short circuit, the battery has potential safety hazards, and the use effect is poor. Contents of the invention [0003] The technical problem to b...
