Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
~6 are please referred to Fig.1, the embodiment of the utility model provides a kind of lithium ion battery bag, including lithium battery group
10th, stent 20, nickel sheet 30, /V cam 40 and lithium ion battery bag protection board 50, the present embodiment lithium battery group 10, stent 20,
The connection mode of nickel sheet 30 and /V cam 40 and the Chinese invention patent that application publication number is CN107256984A are essentially identical,
I.e. stent 20 is arranged to two, wraps invest 10 both ends of lithium battery group respectively, and /V cam 40 sets at least to two, and successively
It is disposed therein on a stent 20, the lithium ion battery bag protection board 50 being connected on two stents 20 can be limited
Position, since /V cam 40 needs carrying out lithium ion battery bag protection board 50 on the direction of the bearing surface of stent 20
/V, so avoid nickel sheet 30 and lithium ion battery bag protection board 50 weld after lithium ion battery bag protection board 50 and stent 20 it
Between still remain gap, while it can avoid lithium ion battery bag protection board 50 from being slided along 20 width of stent, ensure nickel sheet
30 stability assembled with lithium ion battery bag protection board 50, and to reach above-mentioned two effect, then /V cam 40 must be right
A side and upper side of lithium ion battery bag protection board 50 are carried out at the same time /V, but when /V cam 40 is to lithium ion battery
The upper side of bag protection board 50 must use horizontal to be inserted into when carrying out /V, and horizontal insertion can not then meet nickel sheet 30
Vertical is inserted into, therefore during its assembling lithium ion battery bag protection board 50 and/or /V cam 40 is needed to carry out the shape of certain angle
Become, assembly difficulty is big, and when one of component is damaged, dismounting difficulty is also very big.
In view of this, as shown in Figure 1, the present embodiment improves lithium ion battery bag protection board 50, i.e. this implementation
Example lithium ion battery bag protection board 50 includes 51 and at least two supporter 52 of protection board body, and the protection board body 51 is close
Its first side 511 and second side 512 offer at least two first pilot holes 513 and the second pilot hole 514 respectively, at least
Two 513 and second pilot holes 514 of the first pilot hole are along the length side of the first side 511 of the protection board body 51
To setting gradually；First pilot hole 513 include along 511 length direction of first side arrange the first mounting hole 513a and by
First mounting hole 513a extends vertically the first guide hole 513b to be formed to first side 511, and second pilot hole 514 includes edge
The the second mounting hole 514a and vertically prolong from the second mounting hole 514a to first side 511 that 511 length direction of first side is arranged
Stretch the second guide hole 514b to be formed；As shown in figure 3, when assembly is carried out, lithium ion battery bag protection board 50 can be connected to two
A stent 20, and nickel sheet 30 can coordinate the first guide hole 513b of insertion remote away from first mounting hole 513a one end or the second guide hole 514b
From second mounting hole 514a one end, then protection board body 51 is promoted to be moved along the first guide hole 513b length directions, then nickel sheet 30
Moved along the first guide hole 513b or the second guide hole 514b, and when protection board body 51 move to nickel sheet 30 respectively with the first mounting hole
When 513a and the second mounting hole 514a aligns, then protection board body 51 then coordinates insertion limit convex with respect to 511 one side of first side
In button 40, protection board body 51 is promoted to be moved along the first mounting hole 513a directions, as shown in figure 4, then multiple nickel sheet 30 are matched somebody with somebody respectively
It closes part and is built in the first mounting hole 513a or the second mounting hole 514a, realize the convenient of lithium ion battery bag protection board 50
Formula is assembled, and is avoided lithium ion battery bag protection board 50 or /V cam 40 in assembling process and is carried out deformation and cause its damage.
As shown in Fig. 1, Fig. 3, Fig. 4, the first guide hole 513b described in the present embodiment runs through away from first mounting hole 513a one end
The first side 511.Moreover, the same length of the first guide hole 513b and the second guide hole 514b, and with /V cam 40
Mutually agree with.And the width of the first guide hole 513b and the second guide hole 514b slightly larger than be inserted into its in nickel sheet 30 width, first
The width of mounting hole 513a and the second mounting hole 514a then slightly larger than the thickness for the nickel sheet 30 being inserted into it, can minimize first
The area that 513 and second pilot hole 514 of pilot hole occupies improves the utilization rate of protection board body 51.
Due to the present embodiment protection board body 51 assembling when, opposite brackets 20 carried out in the horizontal plane longitudinal direction and
Horizontal movement, the component easily led on protection board body 51 rubs with stent 20, and then causes above-mentioned component
It is damaged, therefore as shown in Figure 5, Figure 6, lithium ion battery bag protection board 50 further includes at least two supporters described in the present embodiment
52, each supporter 52 is perpendicularly fixed at the supporting rod 521 of 51 one side of protection board body and arranged on institute including one end
The multi-directional ball 522 of 521 free end end face of supporting rod is stated, and in order to ensure the stability of its support, supporter described in the present embodiment
52 be four, and is set respectively close to the first side 511 and 512 both ends of second side, i.e., when protection board body 51 is opposite
When stent 20 moves in the horizontal plane, multi-directional ball 522 can be slided in stent 20 with respect to the one side of protection board body 51, favourable
In improving 51 opposite brackets of protection board body, 20 fixed stability, the member on protection board body 51 in its motion process is also avoided
Device rubs with stent 20.
As shown in Fig. 2, Fig. 6, and in order to improve the precision that supporter 52 coordinates with stent 20, stent 20 described in the present embodiment
On be provided with the supporter 52 one-to-one at least two support guide groove 21, since the present embodiment supporter 52 is arranged to
Four, then guide groove 21 is supported to be also configured as four, and each support guide groove 21 exists in " 7 " font with protection board body 51
The direction and distance that opposite brackets 20 move in horizontal plane are engaged, and coordinate to ensure supporting item 52 with supporting guide groove 21
Stability, 21 bottom of the present embodiment support guide groove are arranged to the arc agreed with 522 phase of multi-directional ball.
Specific embodiment of the present utility model described above does not form the restriction to scope of protection of the utility model.
The various other corresponding changes and deformation that any technical concept according to the present utility model is made, should be included in this practicality
In new scope of the claims.
