Embodiment 1

[0099] Such as Figure 1-7 As shown, the present embodiment discloses a locking mechanism 100 for a battery pack (not shown). The locking mechanism 100 includes: a lock base 110 , a lock tongue 120 and a reset component 130 . The lock base 110 is provided with an opening 111 and a cavity 112 extending from the opening 111 , the opening 111 is used for the lock shaft 200 mounted on the battery pack to enter the cavity 112 . The lock tongue 120 can rotate relative to the lock base 110 to change between an unlocked state and a locked state. When the deadbolt 120 is in the locked state, that is figure 1 , figure 2 as well as Figure 4 In the state shown, the lock tongue 120 can prevent the lock shaft 200 from leaving the cavity 112 from the opening 111 . The reset part 130 is arranged on the lock base 110 and the reset part 130 acts on the lock tongue 120. The reset part 130 can be elastically deformed. The reset part 130 is used to make the lock tongue 120 rotate in a locki...

Embodiment 2

[0126] This embodiment discloses a locking mechanism for a battery pack, the structure of which is generally similar to Embodiment 1, except that the structure of the reset component 130 is different from Embodiment 1.

[0127] In this example, if Figure 10 As shown, the reset component 130 includes two connecting parts 132 , two spiral parts 133 and one contact part 131 . The two connecting parts 132 are respectively connected to the outer sides of the two helical parts 133 , and the contact part 131 is connected between the two helical parts 133 .

Abstract

The invention discloses a locking mechanism for a battery pack, a quick-change bracket assembly and an electric vehicle. The locking mechanism comprises a locking base, a locking tongue and a reset part; the locking base is provided with an opening and a cavity extending from the opening; the locking tongue can rotate relative to the locking base so as to be changed to be in an unlocking state ora locking state, and when being in the locking state, the locking tongue can prevent a locking shaft from leaving from the cavity from the opening; and the reset part is arranged on the locking base,acts on the locking tongue, and is used for enabling the locking tongue to rotate in a locking direction so as to be reset to be in the locking state from the unlocking state. The reset part is arranged, the locking tongue is conveniently reset to be in the locking state from the unlocking state, thus the battery pack is convenient to mount and lock, and under the effect of the reset part, the locking tongue is not easily changed to be in the unlocking state, so that locking is more reliable; and the locking mechanism can provide the function of secondary locking or locking protection for thebattery pack, and used for preventing the battery pack from falling when locking of an existing device loses efficacy, and safety performance is improved.

Description

technical field [0001] The invention relates to a locking mechanism for a battery pack, a quick-change bracket assembly and an electric vehicle. Background technique [0002] The battery pack installation methods of existing electric vehicles are generally divided into fixed type and replaceable type, wherein the fixed type battery pack is generally fixed on the car, and the car is directly used as the charging object when charging. The replaceable battery pack is generally installed in a movable manner, and the battery pack can be removed at any time and replaced with a new battery pack. [0003] In the process of replacing a new battery pack, the locking and unlocking of the battery pack is involved. Generally speaking, lock shafts are installed on the left and right sides of the battery pack; the locking device is fixed on the quick-change bracket to assemble a quick-change bracket assembly, and the quick-change bracket assembly is then installed on the chassis of the el...
