Embodiment 1

[0100] like 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 member 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 deadbolt 120 is rotatable relative to the lock base 110 to change between an unlocked state and a locked state. When the lock tongue 120 is in the locked state, that is, figure 1 , figure 2 as well as Figure 4 In the state shown, the locking tongue 120 can prevent the locking shaft 200 from exiting the cavity 112 from the opening 111 . The reset member 130 is provided on the lock base 110 and acts on the lock tongue 120, the reset member 130 can be elastically deformed, and the reset member 130 is used to make the lock tongue 120 rotate in a locking dire...

Embodiment 2

[0127] This embodiment discloses a locking mechanism for a battery pack, the structure of which is generally similar to that of Embodiment 1, except that the structure of the reset component 130 is different from that of Embodiment 1.

[0128] In this embodiment, as Figure 10 As shown, the reset part 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 spiral parts 133 , and the contact part 131 is connected between the two spiral 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 lock base provided with an opening and a cavity extending from the opening; the spring bolt can rotate relative to the lock base so as to change between an unlocking state and a locking state, and when the spring bolt is in the locking state, the spring bolt can prevent the lock shaft from leaving the cavity from the opening; the reset component is arranged on the lock base, acts on the spring bolt and is used for enabling the spring bolt to rotate in the locking direction so that the spring bolt can be reset to the locking state from the unlocking state. The reset component is arranged, so that the spring bolt can be conveniently reset from the unlocking state to the locking state, the battery pack is convenient to install and lock, under the action of the reset component, the spring bolt cannot be easily changed into the unlocking state, and locking is more reliable; and the locking mechanism can provide a secondary locking or locking protection function for the battery pack, and is used for preventing the battery pack from falling off when the locking of the existing device fails, so that the safety performance is improved.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of December 29, 2017, an application number of 2017114788216, and an invention-creation title of "locking mechanism for battery pack, quick-change bracket assembly and electric vehicle". technical field [0002] The invention relates to a locking mechanism for a battery pack, a quick-change bracket assembly and an electric vehicle. Background technique [0003] The existing battery pack installation methods of electric vehicles are generally divided into fixed type and replaceable type. The fixed 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 an active way, and the battery pack can be removed at any time and replaced with a new battery pack. [0004] In the process of replacing a new battery pack, the locking and unlocking of the battery pack is invol...
