It is more.The power battery pack of the electric car of the prior art lacks protective device, inadequate to the protection of battery pack, there is peace
Full hidden danger, battery pack are easy to be worn damage, the safety of battery pack internal wiring are influenced, so as to shorten making for battery pack
Use the service life.
Utility model content
For above-mentioned problems of the prior art, the purpose of this utility model is to provide one kind can avoid in appearance
State the automobile power cell packet guard box of technological deficiency.
In order to realize above-mentioned purpose of utility model, the technical scheme that the utility model is provided is as follows:
A kind of automobile power cell packet guard box, including box cover, sealing ring, lower box, multiple ears retainers and
Multiple outer-hexagonal fasteners, the lower edge of box cover are formed with first edge extension, and the upper end-face edge of lower box is formed
There is second edge extension, is offered on sealing ring, first edge extension and second edge extension multiple and described more
The bolt hole that a outer-hexagonal fastener matches, outer-hexagonal fastener are sequentially inserted into ears retainer, first edge extension, close
Seal and bolt hole on second edge extension are simultaneously tightened.
Further, sealing ring is made of flexible material.
Further, the flexible material is rubber material.
Automobile power cell packet guard box provided by the utility model, structure is simple, and easy to maintenance, reliability is higher, energy
It is enough to protect battery pack well, the safety and durability of battery pack are greatly improved, the closing to battery pack is can be realized and protects
Shield, extends the service life of battery pack, can meet the needs of practical application well.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and specifically
Embodiment is described further the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.Based on the embodiments of the present invention, those of ordinary skill in the art are not having
Every other embodiment obtained under the premise of creative work is made, is fallen within the protection scope of the utility model.
As Figure 1-Figure 4, a kind of automobile power cell packet guard box, including box cover 1, sealing ring 4, lower box 5,
Multiple ears retainers 3 and multiple outer-hexagonal fasteners 2, the lower edge of box cover 1 are formed with first edge extension 6,
The upper end-face edge of lower box 5 is formed with second edge extension 7；The ring width of sealing ring 4, the width of first edge extension 6 and
Second edge extension 7 it is of same size；It is offered on sealing ring 4, first edge extension 6 and second edge extension 7
Multiple bolts hole to match with the multiple outer-hexagonal fastener 2, and multiple bolts hole on sealing ring 4, first edge are prolonged
Multiple bolts hole in extending portion 6 are corresponding with the positions and dimensions of multiple bolts hole on second edge extension 7.Sealing ring
4 can be made of flexible material (such as rubber material).Confession and power battery pack are offered on box cover 1 and lower box 5
The hole that the conducting wire being connected stretches out.
When assembly, power battery pack is put into lower box 5, is then placed on the second edge extension 7 of lower box 5
Good sealing ring 4, then covers box cover 1, makes to open up on sealing ring 4, first edge extension 6 and second edge extension 7
Multiple bolts hole up and down be aligned, on each bolt hole of first edge extension 6 place an ears retainer 3, then
Outer-hexagonal fastener 2 is sequentially inserted on ears retainer 3, first edge extension 6, sealing ring 4 and second edge extension 7
Bolt hole in, after all ears retainers 3 and outer-hexagonal fastener 2 are all installed in place, with torque spanner by defined
Torque value applies torsion to all outer-hexagonal fasteners 2 to which outer-hexagonal fastener 2 to be tightened in bolt hole.Finally, will be double
The upward bending of the short side of ear retainer 3, is bonded with the edge of outer-hexagonal fastener head, then by the long side of ears retainer 3 to
Lower bending is bonded with the second edge extension 7 of lower box 5, until completing after the whole bendings in place of all ears retainers 3
Assembly.
Automobile power cell packet guard box provided by the utility model, structure is simple, and easy to maintenance, reliability is higher, energy
It is enough to protect battery pack well, the safety and durability of battery pack are greatly improved, the closing to battery pack is can be realized and protects
Shield, extends the service life of battery pack, can meet the needs of practical application well.
The above-mentioned embodiments merely express the embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that for the ordinary skill of this field
