A vehicle battery mount structure includes: a battery module fixed to a vehicle body; a through pipe disposed in the battery module; a fixing member configured to fix a lower case and an upper case of the battery module; and a through bolt configured to fix the battery module to a vehicle body bottom frame. The through bolt passes through the through pipe and the fixing member and is coupled to the fixing member.

Battery swapping equipment for an electric vehicle and a positioning method for battery swapping equipment. The battery swapping equipment includes: an unlocking mechanism configured to unlock a battery pack locked onto a fast swapping bracket of the electric vehicle; an image collection module to collect a first actual image containing the lock base during an unlocking process of the battery pack; a storage module configured to store a first standard image collected by the image collection module when the battery swapping equipment is located in a battery swapping position, the first standard image including the lock base; a positioning judgement module to judge whether the battery swapping equipment is located in the battery swapping position according to the first actual image and the first standard image; if not, generating a first moving instruction according to a judged result; a moving mechanism to move according to the first moving instruction.

An energy storage unit for a motor vehicle has a support frame which can be non-destructively detachably mounted on a body of the motor vehicle and a plurality of storage modules for storing electrical energy which can be mounted on the support frame. The storage modules are configured as intrinsically sealed units which can be arranged on the support frame from bottom to top in the vertical direction of the vehicle and can be inserted into respective corresponding receiving openings in the support frame.

A locking device includes a lock base. The lock base includes a lock body, a surface of the lock body being provided with a lock groove recessed towards the interior of the lock body, the lock body being internally provided with a lock tongue groove and a lock tongue movably mounted in the lock tongue groove that is in connection with the lock groove; a lock connecting rod movably connected to the lock base through the lock tongue and including a rod member, the rod member driving the lock tongue to move in the lock tongue groove; and a lock shaft including a shaft seat and a shaft rod perpendicularly arranged to a surface of the shaft seat, the shaft rod being inserted into the lock groove of the lock base to perform locking. A fixing seat and an electric vehicle comprising the locking device are disclosed.

A body floor (1) for an electric vehicle (2) has a battery frame (3) that receives battery modules (4). An interior cover (5) separates an interior (6) from the battery modules (4). At least one crossmember (7, 8) extends transverse to a vehicle longitudinal direction (9) and is on the battery side of the interior cover (5). A seat attachment (10) for connecting a vehicle seat (11) is arranged on the interior side of the interior cover (5). The battery modules (4) are attached to the crossmember (7, 8) by the battery frame (3), and the body floor (1) is a supporting component of the body structure of a vehicle (2). The seat attachment (10) is attached to the body floor (1) on the battery side of the interior cover (5). With this construction, the vehicle seat is low while simultaneously arranging battery modules below the vehicle seat.

The invention relates to a system for installation of traction batteries for a vehicle having a chassis comprising at least one load-carrying frame member. A front bracket member and a rear bracket member are adapted to be secured to and project from the frame member of the vehicle for receiving a traction battery between the front bracket member and the rear bracket member. The system also comprises a first and a second slider adapted to be connected to a front and a rear side, respectively, of a traction battery. The sliders are adapted to be mated with the bracket members subsequently to the sliders having been connected to the traction battery, thereby enabling the traction battery by means of the connected sliders to be received by the bracket members and be moved towards the frame member of the vehicle.

An embodiment dash panel structure for a vehicle includes a battery assembly located under a floor of the vehicle, a front subframe located in front of the battery assembly, a dash panel located behind the front subframe and connected to a front of the floor, and a first reinforcing member mounted on a lower portion of the dash panel facing the front subframe.

A vehicle battery assembly mounting structure includes: a mounting bushing provided in a battery assembly to form a space, the space allowing movement in a vertical direction; a fastening bolt disposed to vertically penetrate the space formed by the mounting bushing; and a sleeve assembly. The sleeve assembly is configured to guide the fastening bolt, to elastically prevent the fastening bolt from being separated from the mounting bushing and to elastically support the fastening bolt with respect to the mounting bushing to allow the fastening bolt to move in the mounting bushing.
