Description

Technical Field

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

[0002] The most important component of a new energy vehicle is the battery pack. The new energy battery pack is composed of a battery pack housing and battery modules. The battery pack housing and other vehicle body connectors connect and fix the entire battery pack to the new energy vehicle body. With the continuous development of the battery swapping technology for new energy vehicles, in order to quickly swap batteries, the existing battery packs are designed with a clamping and fixing structure with the vehicle body, eliminating the need for bolt fixation.

[0003] After being impacted by the outside world, the battery pack of a new energy vehicle is prone to explosion and fire, seriously affecting the life and property safety of the vehicle and personnel. However, the traditional connectors between the battery pack and the vehicle body can only achieve the purpose of quick battery swapping through a single snap connection method, and cannot quickly handle emergencies such as fire and explosion of the new energy battery pack, resulting in relatively large potential safety hazards. For this reason, we have proposed a vehicle body connector that can handle emergencies for fire and explosion battery packs. Summary of the Invention

[0004] The purpose of the present invention is to provide a carbon fiber composite vehicle body connector for new energy vehicles to solve the problems raised in the background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A carbon fiber composite vehicle body connector for new energy vehicles, including a battery pack housing. On both sides of the battery pack housing, evenly distributed connection blocks are fixedly connected. On the upper side of the battery pack housing, two groups of connectors two are provided, and multiple groups of connectors one are arranged between the connectors two and the connection blocks.

[0006] The connector one includes an upper connector and a lower connector. The upper connector is connected to the connector two, and the lower connector is connected to the connection block. The upper connector and the lower connector are fixed by clamping.

[0007] Both the battery pack housing and the connection blocks are made of carbon fiber composite materials.

[0008] After the lower connector rotates, it can be clamped with the connector two. Through double clamping connection, the battery pack housing and the vehicle body can have two connection states.

[0009] Furthermore, the upper connecting member and the lower connecting member are rotationally symmetric about the centers of both. The upper connecting member and the lower connecting member both include a docking housing, a fixing block, a tension spring, a rotating disk, a fixing column, a clamping rod, a first movable assembly, and a second movable assembly. A fixing block is fixedly connected to the outer side of the docking housing. A first movable assembly is fixedly connected to the inner side of the docking housing. A rotating disk is rotatably connected to the outer side of the first movable assembly. Fixing columns are fixedly connected to both the rotating disk and the fixing block. A tension spring is fixedly connected between the two groups of fixing columns. A clamping rod is rotatably connected to the rotating disk. A second movable assembly is fixedly connected to the outer side of the docking housing. A groove is formed in the rotating disk, and the groove corresponds to the clamping rod on the opposite side.

[0010] Furthermore, the first movable assembly includes a first fixing cover, a first bearing, and a first fixing shaft. The first fixing shaft is fixedly connected to the inner side of the docking housing. The first bearing is sleeved on the outer side of the first fixing shaft. The first bearing is arranged on the inner side of the rotating disk, and the outer side wall of the first bearing is tightly clamped with the inner side wall of the rotating disk. A first fixing cover is fixedly connected to the side of the rotating disk away from the first bearing.

[0011] Furthermore, the second movable assembly includes a second fixing cover, a second bearing, and a second fixing shaft. The second fixing shaft is fixedly connected to the outer side of the docking housing. The second bearing is sleeved on the outer side of the second fixing shaft. The second fixing cover is arranged on the side of the second bearing away from the first movable assembly.

[0012] Furthermore, the first connecting member further includes a first pushing assembly and a mounting member. The first pushing assembly is mounted on the upper connecting member, and the mounting member is mounted on the lower connecting member.

[0013] Furthermore, the first pushing assembly includes a first electric telescopic rod and a connecting rod. The first electric telescopic rod is fixedly connected to the outer side of the docking housing at the upper connecting member through a rectangular block. The connecting rod is fixedly mounted on the rotating disk at the upper connecting member. The first electric telescopic rod corresponds to the connecting rod.

[0014] Furthermore, the mounting member includes a clamping column and a connecting shell. The connecting shell is arranged on the outer side of the second bearing at the lower connecting member. The second bearing at the lower connecting member is clamped inside the connecting shell. The second fixing cover at the lower connection is fixedly connected to the connecting shell. The clamping column is fixedly connected to the outer side of the docking housing at the lower connecting member. The connecting shell is fixedly connected to the connecting block.

[0015] A fixing shell is arranged on the outer side of the second bearing at the upper connection. The second bearing at the upper connection is clamped inside the fixing shell. The second fixing cover at the upper connection is fixedly connected to the fixing shell.

[0016] Further, the second connecting member includes a vehicle body connecting plate, a mounting block, a motion assembly, and a clamping member. An upper side of the fixed housing is fixedly connected to the mounting block. An upper side of the mounting block is fixedly connected to the vehicle body connecting plate. The vehicle body connecting plate is provided with a motion assembly, a clamping member, and a second pushing assembly.

[0017] Further, the motion assembly includes a fixed cylinder, a first motion rod, a spring, a sliding plate, and a second motion rod. Two groups of fixed cylinders are fixedly connected to the vehicle body connecting plate. The first motion rod is slidably connected to an inner side of the fixed cylinder. The spring is sleeved on an outer side of the first motion rod. A lower side of the first motion rod is fixedly connected to the sliding plate. The second motion rod is slidably connected to an inner side of the sliding plate. A chute corresponding to the sliding plate is formed on the second motion rod.

[0018] Then, under the action of gravity and through the second moving assembly, the first connecting member starts to rotate, driving the battery pack housing to move downward, separating the battery pack housing from the vehicle body. Since the sliding plate is slidably connected to the second motion rod and a chute corresponding to the sliding plate is formed on the second motion rod, the spring on the first motion rod provides a supporting force for the second motion rod, enabling the second motion rod, the connecting hook, and the rotating rod to reset under the action of the spring force.

[0019] The clamping member includes a fixed track plate, a rotating rod, and a connecting hook. Two groups of rotating rods are rotatably connected to the second motion rod. A lower side of the rotating rod is fixedly connected to the connecting hook. One side of the connecting hook close to the vehicle body connecting plate is rotatably connected to the fixed track plate. The fixed track plate is fixedly connected to the vehicle body connecting plate. An arc-shaped groove is formed on the fixed track plate, and the arc-shaped groove corresponds to the clamping column.

[0020] Further, the second pushing assembly includes a second electric telescopic rod and a pushing plate. A lower side of the second motion rod is fixedly connected to the pushing plate. The pushing plate is fixedly connected to the vehicle body connecting plate through a rectangular block, and the pushing plate corresponds to the second electric telescopic rod.

[0021] When it is necessary to replace the battery pack for battery swapping operation, an external control system controls the start of the second electric telescopic rod. The second electric telescopic rod pushes the pushing plate, and the pushing plate drives the second motion rod fixedly connected thereto to move upward. During the upward movement of the second motion rod, the rotating rod is driven to rotate, and the rotating rod drives the connecting hook to rotate, separating the clamping column inside the fixed track plate from the connecting hook. Under the action of gravity, the clamping column slides downward along the arc-shaped groove inside the fixed track plate.

[0022] Compared with the prior art, the present invention provides a carbon fiber composite material vehicle body connecting member for a new energy vehicle, having the following beneficial effects:

[0023] 1. Through the cooperative action among the battery pack housing, the connecting block, the first connecting piece, and the second connecting piece, the present invention realizes the purpose of connecting the battery pack to the vehicle body through double clamping, 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 material, greatly reducing the weight of the overall vehicle body connecting piece and significantly improving the strength, thus ensuring the stability of the connecting piece.

[0024] 2. By adopting the connection method of double clamping with the vehicle body, the present invention changes the traditional single snap connection method, enabling the battery pack housing and the vehicle body to have two connection states. In the event of a fire or explosion in the battery pack, according to the size of the fire, the state of separation between the battery pack and the vehicle body can be selected, effectively avoiding the phenomenon of the vehicle body catching fire due to the battery pack catching fire, and solving the problem that the existing device cannot quickly respond to the fire and explosion of new energy battery packs, resulting in relatively large potential safety hazards.

[0054] Then, under the action of gravity and through the action of the second movable assembly 38, the first connecting member 3 starts to rotate, driving the battery pack housing 1 to move downward, causing the battery pack housing 1 to separate from the vehicle body. Since the sliding plate 434 and the second motion rod 435 are slidably connected and a chute corresponding to the sliding plate 434 is provided on the second motion rod 435, the spring 433 on the first motion rod 432 provides a supporting force for the second motion rod 435, causing the second motion rod 435, the connecting hook 443, and the rotating rod 442 to reset under the action of the spring force.

[0057] When it is necessary to replace the battery pack for battery swapping operation, the external control system controls the start of the electric telescopic rod two 451. The electric telescopic rod two 451 pushes the pushing plate 452, and the pushing plate 452 drives the moving rod two 435 fixedly connected thereto to move upward. During the upward movement of the moving rod two 435, the rotating rod 442 is driven to rotate, and the rotating rod 442 drives the connecting hook 443 to rotate, so that the clamping column 3101 inside 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-shaped groove inside the fixed track plate 441.

[0058] The specific usage method and function of this embodiment.

[0059] An external new energy battery module is installed inside the battery pack housing 1, and the vehicle body connecting plate 41 is fixed to the external vehicle body. When it is necessary to replace the battery pack for battery swapping operation, the external control system controls the start of the electric telescopic rod two 451. The electric telescopic rod two 451 pushes the pushing plate 452, and the pushing plate 452 drives the moving rod two 435 fixedly connected thereto to move upward. During the upward movement of the moving rod two 435, the rotating rod 442 is driven to rotate, and the rotating rod 442 drives the connecting hook 443 to rotate, so that the clamping column 3101 inside 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-shaped groove inside the fixed track plate 441.

[0060] Then, under the action of gravity and through the action of the movable component two 38, the connecting piece one 3 starts to rotate, driving the battery pack housing 1 to move downward, so that the battery pack housing 1 is separated from the vehicle body. Since the sliding plate 434 is slidably connected to the moving rod two 435, and a sliding groove corresponding to the sliding plate 434 is provided on the moving rod two 435, the spring 433 on the moving rod one 432 provides a supporting force for the moving rod two 435, so that the moving rod two 435, the connecting hook 443, and the rotating rod 442 are reset under the action of the spring force, as shown in the connecting piece two 4.

[0061] When the battery pack housing 1 is initially separated from the vehicle body, the external control system controls the start of the electric telescopic rod one 391, and the electric telescopic rod one 391 pushes the rotating disk 34 at the upper connecting piece to rotate.

[0062] At this time, the rotating disks 34 on the upper and lower sides are respectively connected with the corresponding clamping rods 36, so that 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.

[0063] 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, and 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.

[0064] 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, and after passing over 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.

[0065] 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, thereby exposing the battery pack to the outside, and extinguishing the fire with a fire extinguisher to protect the vehicle from noise.

[0066] When the 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, so that the battery pack is completely separated from the vehicle body and the battery pack is discarded.

[0067] 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 body connector are greatly reduced, and they have strong tensile resistance and excellent fatigue resistance, ensuring the movement stability of the double clamping movement.

[0068] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
