Embodiment 1

[0020] Such as Figure 1~2 As shown, the present invention is an adjustable gap baffle for the installation of a lithium battery pack, including a first baffle 1 and a second baffle 8 that are arranged in parallel and opposite to each other. 1 and the adjustment part between the second baffle 8, the adjustment part includes the first stud 2 set on the first baffle 1 and the corresponding setting on the second baffle 8 and the thread direction of the first stud 2 The opposite second stud 5, and the adjustment body 4 that connects the first stud 2 with the second stud 5, one end of the adjustment body 4 is provided with an internal thread that matches the first stud 2, and the other end is the same as The shaft is provided with an internal thread matching the second stud 5 .

[0021] When assembling, the battery pack 6 can be put into the inside of the battery case 7 first, and then the adjustable gap baffle plate of the present invention for lithium battery pack installation i...

Embodiment 2

[0026] Compared with Embodiment 1, this embodiment differs only in that the adjustment part includes a first internally threaded sleeve disposed on the first baffle and a correspondingly disposed on the second baffle and threaded with the first internally threaded sleeve. The second internally threaded sleeve that rotates in the opposite direction, and the adjusting body that connects the first internally threaded sleeve with the second internally threaded sleeve, one end of the adjusting body is provided with an external thread that matches the first internally threaded sleeve , the other end is coaxially provided with an external thread matched with the second internal thread sleeve. It should be noted that the adjustment distance in this embodiment is determined comprehensively by the length of the internal threads of the first internal thread sleeve and the second internal thread sleeve and the length of the external thread on the adjustment body.

Embodiment 3

[0028] Compared with Embodiment 1, this embodiment differs only in that the adjustment part includes a first stud set on the first baffle and a corresponding screw threaded on the second baffle which is opposite to the first stud. The second internally threaded sleeve, and the adjustment body connecting the first stud with the second internally threaded sleeve, one end of the adjustment body is provided with an internal thread matching the first stud, and the other end is coaxially provided with an internal thread that matches the first stud. The second internally threaded sleeve matches the external thread. It should be noted that the adjustment distance in this embodiment is determined comprehensively by the length of the external thread on the first stud, the length of the internal thread on the second internal thread sleeve, and the length of the external thread and the length of the internal thread on the adjusting body.

[0029] To sum up, the present invention has a sim...

Abstract

The invention provides an interval-adjustable baffle for installation of a lithium battery pack. The interval-adjustable baffle comprises a first baffle, a second baffle, and at least two adjusting parts, wherein the first baffle and the second baffle are arranged in parallel; the plate surfaces of the first baffle and the second baffle are opposite to each other; the at least two adjusting parts are arranged in parallel between the first baffle and the second baffle; each adjusting part comprises a first stud or a first internally threaded sleeve arranged on the first baffle and a second stud or a second internally threaded sleeve correspondingly arranged on the second baffle and opposite to the first stud or the first internally threaded sleeve in thread rotation direction, and an adjusting body for connecting the first stud or the first internally threaded sleeve and the second stud or the second internally threaded sleeve; internal threads or external threads matched with the corresponding first stud or the first internally threaded sleeve are arranged at one end of each adjusting body, and internal threads or external threads matched with the corresponding second studs or the second internally threaded sleeves are coaxially arranged at the other ends of the adjusting bodies; and an interval between the battery pack and a battery shell can be adjusted by the baffle, an error can be eliminated, and the assembly is relatively compact and attractive.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to an adjustable gap baffle for installing lithium battery packs. Background technique [0002] At present, electric vehicles mostly use lithium battery devices to provide power to the vehicle. In order to meet the cruising range and reduce the charging frequency, each electric vehicle needs multiple batteries to form a lithium battery pack. The lithium battery pack is generally fixed in an area that can limit its displacement by the baffle and the battery case, and there is a certain space on the other side of the baffle for the protective plate and the charging and discharging circuit. Usually, the baffle is first fixed on the bottom of the battery case. Due to production errors and assembly errors, it will be difficult to assemble the battery pack, and it will be difficult to disassemble the battery pack in the later stage. It may even be necessary to overturn the lithium battery...
