Abstract
The utility model discloses a kind of locked instrument, which includes：First locking screw and the second locking screw；First locking screw includes the first screw head, the first screw rod middle section and the first screw rod endpiece, and first screw head is equipped with external screw thread；Second locking screw includes the second screw head, the second screw rod middle section and the second screw rod endpiece, and second screw head is hollow and has internal screw thread；It is threadedly coupled between the external screw thread of first screw head and the internal screw thread of second screw head.Not only locking method is simply laborsaving, and being applied to battery modules substantially reduce influence of the length of screw rod to locking mould group will, and the space of PACK will not be occupied when screw design is too long, the effect of locking will not be influenced when screw design is slightly shorter.
Description
Technical field
The utility model relates to battery technology field, in particular to a kind of locked instrument and battery modules.
Background technique
As country widelys popularize New-energy electric vehicle, the manufacturing technology level of PACK is also increasingly advanced by leaps and bounds.
Current PACK production method existing on the market is each has something to recommend him, and the connection type of mould group is also different in PACK.
Currently, the mould group connection type of most convenient is that module is connect locking, original side with module using locking screw
Case is to calculate the length of locking screw, is sealed in from one end of mould group, and other end string goes out, and is then locked with nut.
But the shortcomings that this scheme is that locking screw design is too long, it is originally just nervous that one end outstanding can occupy PACK
Inner space.And design is slightly shorter, because there are gaps between module and module when sealing in mould group, so that one end outstanding is effective
The length that locks is inadequate, causes that mould group can not be locked.
Utility model content
The utility model embodiment provides a kind of locked instrument and battery modules, the shadow of the length of screw rod to locking mould group
Sound will substantially reduce.
In a first aspect, the utility model embodiment provides a kind of locked instrument, which includes：First locking spiral shell
Bar and the second locking screw；First locking screw includes the first screw head, the first screw rod middle section and the first screw rod endpiece, institute
The first screw head is stated equipped with external screw thread；Second locking screw includes the second screw head, the second screw rod middle section and the second spiral shell
Bar endpiece, second screw head are hollow and have internal screw thread；The external screw thread of first screw head and second screw rod
It is threadedly coupled between the internal screw thread of head.
Preferably, the length of the first locking screw is less than or equal to the second locking screw.
Preferably, the length of first screw head is less than or equal to the length of second screw head.
Second aspect, the utility model embodiment provide a kind of battery modules, which includes：At least two electricity
Any locked instrument, locked instrument lock together the battery module being arranged side by side in pond module and first aspect.
Preferably, the length of the second locking screw is less than or equal to the length for the battery modules being all arranged side by side.
Compared with prior art, the utility model at least has the advantages that：
The slightly long or slightly shorter space that can occupy PACK of original locking screw design or the mould group that can not lock, and this is practical new
The locking mode of mould group has been changed to two screw rods and has passed through the mutually matched mode of screw thread, the length pair of screw rod in module internal by type
The influence of locking mould group will substantially reduce, and the space of PACK will not be occupied when screw design is too long, when screw design is slightly shorter also not
It will affect the effect of locking.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is this
Some embodiments of utility model, for those of ordinary skill in the art, without creative efforts, also
Other drawings may be obtained according to these drawings without any creative labor.
Fig. 1 is a kind of structural schematic diagram for locked instrument that the utility model one embodiment provides；
Fig. 2 is a kind of explosive view for battery modules that the utility model one embodiment provides；
Fig. 3 is a kind of overall structure diagram for battery modules that the utility model one embodiment provides.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments, based on the implementation in the utility model
Example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all belongs to
In the range of the utility model protection.
As shown in Figure 1, the utility model embodiment provides a kind of locked instrument, which includes：First locking
Screw rod 1 and the second locking screw 2；First locking screw 1 includes the first screw head 13, the first screw rod middle section 12 and the first spiral shell
Bar endpiece 11, first screw head 13 are equipped with external screw thread；Second locking screw 2 includes the second screw head 23, second
Screw rod middle section 22 and the second screw rod endpiece 21, second screw head 23 are hollow and have internal screw thread；First screw head
It is threadedly coupled between 13 external screw thread and the internal screw thread of second screw head 23.
The length of the first locking screw is less than or equal to the second locking screw in one embodiment of the utility model.It is described
The length of first screw head is less than or equal to the length of second screw head.
As shown in Figures 2 and 3, the utility model embodiment provides a kind of battery modules, which includes：At least
The locked instrument that two battery modules and any of the above-described embodiment provide, locked instrument lock the battery module being arranged side by side
Together.
The first screw rod and the second screw rod are sealed in by the both ends of battery modules respectively in this embodiment, in battery modules
Inside is used to be threadedly engaged locking mould group.
The length of the second locking screw is less than or equal to the electricity being all arranged side by side in one embodiment of the utility model
The length of Chi Mo group.
The locking mode of mould group two screw rods have been changed in this embodiment to cooperate in module internal by screw thread
Mode, not only locking method is simply laborsaving, and the length of screw rod to locking mould group influence will substantially reduce, screw design
The space that PACK will not be occupied when too long will not influence the effect of locking when screw design is slightly shorter.
Finally, it should be noted that：The above is only the preferred embodiment of the present invention, is merely to illustrate practical
Novel technical solution, is not intended to limit the protection scope of the utility model.It is all the spirit and principles of the utility model it
Interior done any modification, equivalent substitution, improvement and etc., are all contained in the protection scope of the utility model.
