Description

Technical Field

[0001] The present invention relates to the technical field of vehicle body connectors, and in particular to a carbon fiber composite vehicle body connector for new energy vehicles. Background Art

[0002] The most important component of new energy vehicles is the battery pack. The new energy battery pack consists of a battery pack shell and a battery module. The battery pack shell and other body connectors connect and fix the entire battery pack to the new energy vehicle body. With the continuous development of battery replacement technology for new energy vehicles, the existing battery pack is designed with a fixed structure that is snapped onto the body for quick battery replacement, without the need for bolts.

[0003] New energy vehicle battery packs are prone to explosions and fires after being impacted, seriously impacting the safety of the vehicle and its passengers. Traditional battery pack-to-body connectors rely on a single snap-on connection for quick battery replacement, but are unable to provide rapid emergency response to fires and explosions, leading to significant safety hazards. Therefore, we have proposed a vehicle body connector that can handle fires and explosions. Summary of the Invention

The connecting rod is fixedly installed on the rotating disk at the upper connecting piece, and the electric telescopic rod corresponds to the connecting rod.

[0013] Furthermore, the mounting part includes a clamping column and a connecting shell. A connecting shell is provided on the outer side of the second bearing at the lower connecting part. The second bearing at the lower connecting part is clamped on the inner side of the connecting shell. The second fixing cover at the lower connecting part is fixedly connected to the connecting shell.

[0014] A fixed shell is provided on the outer side of the second bearing at the upper connection, the second bearing at the upper connection is clamped on the inner side of the fixed shell, and the second fixed cover at the upper connection is fixedly connected to the fixed shell.

The inner side of the sliding plate is slidably connected to the motion rod 2. A sliding groove corresponding to the sliding plate is provided on the motion rod 2.

[0017] Then, under the action of gravity, the connecting member 1 starts to rotate through the action of the movable component 2, driving the battery pack shell to move downward, so that the battery pack shell is separated from the vehicle body.

[0021] When the battery pack needs to be replaced for battery replacement, the external control system controls the activation of the electric telescopic rod 2, which pushes the push plate. The push plate drives the moving rod 2 fixedly connected to it to move upward. The moving rod 2 drives the rotating rod to rotate during the upward movement, and the rotating rod drives the connecting hook to rotate, so that the clamping column on the inner side of the fixed track plate is separated from the connecting hook. Under the action of gravity, the clamping column slides downward along the arc groove on the inner side of the fixed track plate.

[0022] Compared with the prior art, the present invention provides a carbon fiber composite body connector for new energy vehicles, which has the following beneficial effects:

[0023] 1. The present invention achieves the purpose of connecting the battery pack to the vehicle body through double clamping through the cooperation between the battery pack housing, the connecting block, the first connector, and the second connector, thereby ensuring the stability of the connection between the battery pack and the vehicle body. At the same time, the battery pack housing and the connecting block are made of carbon fiber composite materials, which greatly reduces the weight of the overall vehicle body connector and greatly improves the strength, thereby ensuring the stability of the connector.

[0024] 2. This invention uses a dual-clip connection method to connect to the vehicle body, replacing the traditional single-clip connection method. This allows the battery pack housing to have two connection states with the vehicle body. In the event of a battery pack fire or explosion, the battery pack and vehicle body can be separated according to the severity of the fire. This effectively prevents the vehicle body from being burned due to a battery pack fire, and solves the problem that existing devices cannot quickly respond to new energy battery pack fires and explosions, which leads to significant safety hazards.

[0054] Then, under the action of gravity, the connecting member 3 starts to rotate through the action of the movable component 2 38, driving the battery pack shell 1 to move downward, so that the battery pack shell 1 is separated from the vehicle body. Since the sliding plate 434 and the moving rod 2 435 are slidingly connected, the moving rod 2 435 is provided with a sliding groove corresponding to the sliding plate 434, and then the spring 433 on the moving rod 1 432 provides support force for the moving rod 2 435, so that the moving rod 2 435, the connecting hook 443, and the rotating rod 442 are reset under the action of the spring force.

[0059] The specific usage and function of this embodiment.

[0060] An external new energy battery module is installed inside the battery pack shell 1, and the body connecting plate 41 is fixed to the external body. When the battery pack needs to be replaced for battery replacement operation, the external control system controls the start of the electric telescopic rod 2 451, and the electric telescopic rod 2 451 pushes the pushing plate 452, and the pushing plate 452 drives the moving rod 2 435 fixedly connected to it to move upward. During the upward movement, the moving rod 2 435 drives the rotating rod 442 to rotate, and the rotating rod 442 drives the connecting hook 443 to rotate, so that the clamping column 3101 on the inner side of the fixed track plate 441 is separated from the connecting hook 443. Under the action of gravity, the clamping column 3101 slides downward along the arc groove on the inner side of the fixed track plate 441.

[0061] Then, under the action of gravity, the connecting member 3 starts to rotate through the action of the movable component 2 38, driving the battery pack shell 1 to move downward, so that the battery pack shell 1 is separated from the vehicle body. Since the sliding plate 434 and the moving rod 2 435 are slidingly connected, the moving rod 2 435 is provided with a sliding groove corresponding to the sliding plate 434, and then the spring 433 on the moving rod 1 432 provides support force for the moving rod 2 435, so that the moving rod 2 435, the connecting hook 443, and the rotating rod 442 are reset under the action of the spring force, as shown in the connecting member 2 4.

[0062] After the battery pack housing 1 is initially separated from the vehicle body, the external control system controls the activation of the electric telescopic rod 391, which pushes the rotating disk 34 at the upper connecting member to rotate.

[0063] Since the rotating disks 34 on the upper and lower sides are respectively connected to the corresponding clamping rods 36, after rotating to a certain angle, the clamping rods 36 are separated from their corresponding rotating disks 34, so that the upper connecting part is separated from the lower connecting part, and the battery pack is completely separated from the vehicle body.

[0064] After replacing the new battery pack, first align the upper connecting piece with the lower connecting piece, and the clamping rod 36 contacts the corresponding rotating disk 34 along the respective channels on the inner side of the docking shell 31, and then push the rotating disk 34 to rotate through the clamping rod 36, so that the clamping rod 36 is clamped with the groove on the rotating disk 34. Under the tension of the tension spring 33, the rotating disk 34 is reset, and then the upper connecting piece and the lower connecting piece are connected to each other in place.

[0065] Start the external lifting mechanism to push the battery pack shell 1, so that the battery pack shell 1 rotates around the fixed axis 2 383 through the connecting piece 1 3, and then the clamping column 3101 enters the fixed track plate 441, pushing the connecting hook 443 to rotate. After passing the connecting hook 443, the connecting hook 443 fixes it, achieving the purpose of double clamping and fixing, and the battery replacement operation is completed.

[0066] When the battery pack catches fire or explodes, and the fire is small, the external control system detects this phenomenon through the external temperature sensor, and controls the clamping column 3101 to separate from the connecting hook 443, so that the battery pack shell 1 is initially separated from the vehicle body, and then the battery pack is exposed to the outside, and the fire is extinguished by a fire extinguisher to protect the vehicle noise.

[0067] When a battery pack catches fire or explodes, and the fire is large, after the battery pack is initially separated from the vehicle body, the external system controls the upper connector to separate from the lower connector, completely separating the battery pack from the vehicle body and discarding the battery pack.

[0068] Since the battery pack shell 1 and the connecting block 2 are made of carbon fiber composite materials, the overall weight of the battery pack and the weight of the vehicle body connector are greatly reduced. In addition, they have strong tensile strength and excellent fatigue resistance, ensuring the stability of the double-clamping movement.

[0069] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
