Description

Technical Field

[0001] This article belongs to the technical field of battery pack locking and unlocking mechanisms, specifically relating to a rotary cylinder type battery pack locking and unlocking mechanism. Background Technology

[0002] New energy vehicles refer to vehicles that are powered by onboard power sources, use electric motors to drive the wheels, and meet all road traffic and safety regulations. They use electricity stored in power batteries to start.

[0003] When the power battery is depleted, it needs to be charged immediately to ensure the normal operation of the electric vehicle. Although charging infrastructure is constantly being improved in various places to make charging more convenient, in situations where users are pressed for time, the main solution to avoid excessively long charging times is to replace the electric vehicle's power battery. When the power battery is low, a fully charged battery pack can be directly replaced at a charging station. In current technology, the power battery of an electric vehicle is generally fixedly connected to the vehicle body or bolted on, which results in a complex and time-consuming process for installing and removing the battery. Summary of the Invention

[0004] This paper proposes a rotary cylinder-type battery pack locking and unlocking mechanism. The battery pack is installed inside a battery mounting frame. The battery mounting frame includes a fixed slot plate, a movable slot plate, a rotary cylinder, and a locking cylinder. The movable slot plate is located on the inner side of the fixed slot plate, and the rotary cylinder is located on the top of the fixed slot plate. The rotary cylinder passes through the fixed slot plate and connects to the movable slot plate. The bottom of the fixed slot plate has an inclined bottom support edge, and the outer side of the end side of the fixed slot plate has a locking cylinder. The interior of the fixed slot plate facing the locking cylinder has a locking hole, and the edge of the movable slot plate opposite the locking hole has a locking clip. The battery pack can be quickly locked and fixed by oblique rotation. Furthermore, the locking cylinder can fix the movable slot plate, preventing it from rotating after the battery pack installation is completed. This enables rapid installation and removal of the battery pack, and the installation is simple and the assembly is secure.

[0005] The fixed groove plate has a C-shaped cross-section. The bottom of the side of the fixed groove plate is vertically provided with a bottom support edge. The left front and right rear of the side of the fixed groove plate are both provided with a horizontally through-hole rotating opening. The rotating opening and the edge of the side of the fixed groove plate are provided with a movable arc. Through the fixed groove plate with the side opening, the movable groove plate can be rotated inside the fixed groove plate, which facilitates the rotation installation.

[0006] The bottom support edge is a right-angled triangle. The long right-angled side of the bottom support edge is connected to the side of the fixing slot plate, and the short right-angled side of the bottom support edge is flush with the opposite side of the fixing slot plate. The hypotenuses of the bottom support edge are aligned and parallel to each other. The bottom support edge provides bottom support for the battery pack, so that the battery pack can be stably fixed inside the fixing slot plate.

[0007] The movable slot plate is a rectangular four-fold plate. The left rear part and right front part of the movable slot plate are both horizontally connected with fitting openings. The inner side of the end face of the movable slot plate with the fitting opening is provided with a locking clip. The battery pack is rotated and fixed by the initial oblique position and the locked position when the movable slot plate is turned upright, so that quick disassembly and assembly can be achieved.

[0008] The locking socket is rectangular, with one side of the locking socket facing outwards communicating with the locking cylinder. The inner side of the locking socket has a rounded transition edge at the outer vertical edge. The surface of the locking clip has a locking hole that runs through it. The locking hole is aligned with the output port of the locking cylinder inside the locking socket. The locking socket and the locking clip work together to lock the fixed slot plate and the movable slot plate, preventing them from rotating. Furthermore, the locking clip is locked by the locking cylinder to prevent rotational displacement.

[0009] The mounting plate is fixedly connected to the car frame to attach the battery pack to the bottom of the car frame.

[0010] Beneficial effects:

[0011] The battery pack can be quickly locked and fixed by oblique rotation, and the movable slot plate can be fixed by locking cylinder to prevent the movable slot plate from rotating after the battery pack is installed. This enables the battery pack to be installed and removed quickly, and the installation is simple and the assembly is firm.

[0012] The movable slot plate can rotate inside the fixed slot plate through the side opening of the fixed slot plate, which facilitates rotational installation.

[0013] The battery pack is supported by the bottom edge, which allows it to be stably secured inside the mounting plate.

[0014] The locking socket and locking clip work together to lock the fixed slot plate and the movable slot plate, preventing them from rotating. The locking clip is then locked with a locking cylinder to prevent rotational displacement. Attached Figure Description

[0018] To enhance understanding of the present invention, the invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only for explaining the invention and do not constitute a limitation on the scope of protection of the invention.

[0019] Fixed slot plate 1, movable slot plate 2, rotary cylinder 3, locking cylinder 4, locking socket 5, locking clip 6, battery pack 7.

[0020] like Figure 1 , 2 As shown;

[0021] A rotary cylinder 3 type battery pack 7 locking and unlocking mechanism is disclosed. The battery pack 7 is disposed inside a battery mounting bracket, which includes a fixed slot plate 1, a movable slot plate 2, a rotary cylinder 3, and a locking cylinder 4. The movable slot plate 2 is provided on the inner side of the fixed slot plate 1, and the rotary cylinder 3 is provided on the top of the fixed slot plate 1. The rotary cylinder 3 passes through the fixed slot plate 1 and is connected to the movable slot plate 2. The bottom of the fixed slot plate 1 is provided with an inclined bottom support edge, and the outer side of the end side of the fixed slot plate 1 is provided with a locking cylinder 4. The interior of the fixed slot plate 1 facing the locking cylinder 4 is provided with a locking hole 5. The edge of the movable slot plate 2 opposite to the locking hole 5 is provided with a locking latch 6. The fixed slot plate 1 has a C-shaped cross-section. The bottom side of the fixed slot plate 1 is provided with a vertical bottom support edge. The left front and right rear sides of the fixed slot plate 1 are both provided with a transversely penetrating rotary cylinder. The movable opening has a movable arc along the edge of the fixed slot plate 1. The bottom support edge is a right-angled triangle with the long right-angled side connected to the side of the fixed slot plate 1 and the short right-angled side flush with the opposite side of the fixed slot plate 1. The hypotenuses of the bottom support edge are aligned and parallel to each other. The movable slot plate 2 is a rectangular four-folded plate. The left rear and right front sides of the movable slot plate 2 have horizontally penetrating openings.
