The purpose of this utility model is to provide high, the easy processing of a kind of intensity, cover plate of power battery that result of use is good.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of cover plate of power battery, comprise cover board body, offer pole column hole on cover board body, be injected with insulation cushion in pole column hole, in the middle of insulation cushion, be fixedly connected with pole, it is characterized in that: the cover board body upper surface middle part is recessed to form groove downwards, recess edge is reinforcement, cover board body lower surface middle part is the outstanding boss that forms downwards, and insulation cushion is positioned at groove, and a wherein side, both sides or three sides in the insulation cushion sidewall are against the inside sidewalls of reinforcement.
According to described cover plate of power battery, it is characterized in that: the front side wall of described insulation cushion and/or rear wall are against the inside sidewalls of reinforcement.
According to described cover plate of power battery, it is characterized in that: the left side wall of described insulation cushion or right side wall are against the inside sidewalls of reinforcement.
According to described cover plate of power battery, it is characterized in that: border, described boss edge is fixedly connected with the assist location step.
The utility model, for insulation anti-rotation integral structure, is provided with a circle reinforcement around cover board body, and this kind of structure significantly increases the intensity of cover plate.Be provided with the insulation cushion of integral type injection moulding in the groove of reinforcement inside, the front and back sidewall of insulation cushion is against on the sidewall of reinforcement, the battery plus-negative plate post is fixed in insulation cushion, the inwall of reinforcement is dead by the insulation cushion hoop, insulation cushion can't be rotated, therefore the pole be fixed together with insulation cushion can not be rotated, result of use is good.
Reinforcement in the utility model, in the side edge thereof moulding, does not affect the material property of side edge thereof, makes the material property of cover plate and aluminum hull be tending towards the same, is easy to welding, and explosion-proof effect is good.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Embodiment mono-:
A kind of cover plate of power battery, as shown in Figure 1, Figure 2 and Figure 3, comprise cover board body 5, on cover board body 5, offer pole column hole, be injected with insulation cushion 4 in pole column hole, be fixedly connected with pole 3 in the middle of insulation cushion 4, cover board body 5 upper surface middle part are recessed to form groove 2 downwards, and groove 2 edges are reinforcement 1, and cover board body 5 lower surface middle parts are the outstanding boss 6 that forms downwards, insulation cushion 4 is positioned at groove 2, and the sidewall of insulation cushion 4 is against the inside sidewalls of reinforcement 1.In the present embodiment, the front side wall of insulation cushion 4 and rear wall all are against the inside sidewalls of reinforcement 1.Boss 6 borders, edge are fixedly connected with assist location step 7.
Embodiment bis-:
A kind of cover plate of power battery, as shown in Fig. 4, Fig. 2 and Fig. 3, comprise cover board body 5, on cover board body 5, offer pole column hole, be injected with insulation cushion 4 in pole column hole, be fixedly connected with pole 3 in the middle of insulation cushion 4, cover board body 5 upper surface middle part are recessed to form groove 2 downwards, and groove 2 edges are reinforcement 1, and cover board body 5 lower surface middle parts are the outstanding boss 6 that forms downwards, insulation cushion 4 is positioned at groove 2, and the sidewall of insulation cushion 4 is against the inside sidewalls of reinforcement 1.In the present embodiment, the front side wall of insulation cushion 4 or rear wall are against the inside sidewalls of reinforcement 1.Boss 6 borders, edge are fixedly connected with assist location step 7.
