Abstract: The disclosure relates to a trunk floor mounting structure for a vehicle, and a vehicle. The trunk floor mounting structure is configured to be arrangeable in a boot of the vehicle, and includes: a floor including a front floor and a rear floor reversibly fixed to the front floor; and a suspension mechanism including a stop member and a limiting member cooperating with each other, the stop member having a fixed end fixed to a lower surface of the rear floor and a movable end capable of extending to a lower surface of the front floor, and the limiting member being configured to be arrangeable on at least one of a left side wall and a right side wall of the boot, wherein when the rear floor is flipped by a predetermined obtuse angle relative to the front floor from an initial position, the movable end abuts against the limiting member such that the rear floor is suspended in a suspended position.

Abstract: The invention refers to a battery lock-up device, a new energy vehicle comprising the battery lock-up device, and a method for installing/detaching a power battery. The battery lock-up device comprises: a connection bracket having a first connection hole and a dual limited position structure; a housing structure having a second connection hole; a press plate and a nut, the press plate comprising a head portion and a pillar portion passing through the first connection hole and the second connection hole, the pillar portion being formed with a threaded portion for engaging with the nut and having a distal end adapted to mate with a rotational operation tool; and an anti-rotation locking member which locks the nut against the housing structure.

Abstract: The present application relates to the field of swapping batteries of electric vehicles, particularly to a quick locking-unlocking assembly. The present application aims at solving the problem in the prior art that each locking mechanism of current electric vehicle power battery has too many parts and sophisticated structure, occupying larger space and thus increasing cost in manufacturing the electric vehicles. The quick locking-unlocking assembly of the application includes: a first sliding block and a second sliding block slidably connected to the electric vehicle body, a retaining sheath fixed to the outer shell of the power battery, a first spring and a second spring for forcing the first and second sliding blocks to move closer to each other, a bolt capable of extending through the retaining sheath and the first and second sliding blocks, and a third spring forcing the bolt away from the vehicle body.
