Specific embodiment
Below with reference to embodiment and attached drawing, the utility model is described in further detail.
As shown in Fig. 1 to Fig. 5, a kind of electric automobile battery box combination plate, including cover plate unit 1, battery mounting base, electricity
Flange 2, cover board buttcover plate 3, reinforcement block 3a, connection bolt 3b, first through hole a, the second through-hole b, third through-hole c, the are protected in pond
Four through-hole d and hold-down support 5, in which:
The cover plate unit 1 is two, and the medial surface of the cover plate unit 1 is equipped with the battery mounting base, the lid
The edge of plate unit 1 is fixed with the cover board buttcover plate 3, and the cover board buttcover plate 3 is towards the outside of the cover plate unit 1；Institute
State that cover board buttcover plate 3 is elongated, the length direction of the cover board buttcover plate 3 moves towards setting, institute along the edge of the cover plate unit 1
The edge for stating cover plate unit 1 is further fixed on the battery protection flange 2, and the battery protection flange 2 is towards the cover plate unit 1
Inside, the battery protection flange 2 move towards setting, the start-stop of the battery protection flange 2 along the edge of the cover plate unit 1
At the corresponding cover plate unit 1 in the both ends of the cover board buttcover plate 3.
All cover plate units 1 are in same plane, pass through the corresponding cover board between two cover plate units 1
Buttcover plate 3 docks；The start-stop position of the battery protection flange 2 of two cover plate units 1 is mutually butted, in two lids
The continuous battery protection flange 2 is formed between plate unit 1；Specifically, the cover board between two cover plate units 1
Buttcover plate 3 is docked according to following technical scheme:
It is distributed along its length on the cover board buttcover plate 3 and is located at by multiple reinforcement block 3a, the reinforcement block 3a
Outside of the cover board buttcover plate 3 close to the side of the cover plate unit 1, reinforcement block 3a while also with the cover plate unit 1
Face connection, to improve the bonding strength between cover board buttcover plate 3 and cover plate unit 1；It is respectively equipped on the reinforcement block 3a described
First through hole a, the first through hole a run through the cover board buttcover plate 3 and the reinforcement block 3a.
In order to guarantee the bonding strength between two cover board buttcover plates 3, enough tie points should be set between
Position, when these connection points on cover board buttcover plate 3 along same lineal layout when, it is two neighboring connection point between spacing just
It can be smaller；It, can be due to the position of part material thickness if being respectively provided with reinforcement block 3a on the corresponding cover board buttcover plate 3 of each connection point
It excessively concentrates and stress is caused to concentrate, reinforcement block 3a pulls the material around other and drops its adjacent material intensity
It is low；And the molding difficulty for ultimately causing cover board buttcover plate 3 is big, stability is poor, intensity decline, is unfavorable for improving two cover board docking
Bonding strength between plate 3.Thus need while considering intensity, formation problems and two cover boards of single cover board buttcover plate 3
Bonding strength, the stability problem of buttcover plate 3, the present embodiment are resolved using following technical scheme:
Multiple second through-hole b are additionally provided on the cover board buttcover plate 3, the second through-hole b runs through the cover board
Buttcover plate 3, multiple second through-hole b are spaced apart with multiple reinforcement block 3a；
On the first through hole a and second adjacent cover board buttcover plate 3 on first cover board buttcover plate 3
The second through-hole b it is corresponding, the second through-hole b on first cover board buttcover plate 3 and second adjacent institute
The first through hole a stated on cover board buttcover plate 3 is corresponding, is equipped in the first through hole a and the corresponding second through-hole b
The same connection bolt 3b；
The head of the bolt 3b is located at the side the second through-hole b, and the bar portion of the connection bolt 3b sequentially passes through institute
The second through-hole b and first through hole a are stated, the bar portion of the connection bolt 3b is threadedly coupled with the first through hole a.
First through hole a and the setting of the second interval through-hole b on the above same cover board buttcover plate 3 are both same cover board pair
Fishplate bar 3 provides enough installation points, and is avoided that cover board buttcover plate 3 caused by excessive reinforcement block 3a is arranged forms difficulty
Greatly, the problem of stability is poor, and intensity declines；It is wrong corresponding between first through hole a and the second through-hole b between two cover plates buttcover plate 3,
And the mounting means of connection bolt 3b, it ensure that the bonding strength and connective stability between two cover plates buttcover plate 3, and keep away
Breakage, the fracture of cover board buttcover plate 3 at the second through-hole b are exempted from.
Furthermore:
The vertical cover plate unit 1 of the battery protection flange 2, the edge of the battery protection flange 2 simultaneously extend outwardly,
The face that extends outwardly of the battery protection flange 2 is equipped at least one described third through-hole c.
The vertical cover plate unit 1 of the cover board buttcover plate 3.
The cover plate unit 1, the battery protection flange and the mounting base are integrally formed；
1 inner wall of cover plate unit is equipped with cover board reinforcing rib, and the cover board reinforcing rib is grid-shaped, the cover plate unit 1
Material be magnesium alloy.
2 edge of battery protection flange is equipped at least one described hold-down support 5, distinguishes on the hold-down support 5
Equipped with the fourth hole d.
Finally, it should be noted that foregoing description is only the preferred embodiment of the utility model, the common skill of this field
Art personnel are under the enlightenment of the utility model, under the premise of without prejudice to the utility model aims and claim, can make
Multiple similar expressions, such transformation are each fallen within the protection scope of the utility model.
