Description

Technical Field

[0001] This invention relates to the field of new energy vehicle battery technology, and in particular to a new energy vehicle battery housing. Background Technology

[0002] The battery box of a new energy vehicle is the core protective shell of the vehicle's power battery system. It mainly consists of an upper sealing cover and a lower support tray. It is mainly made of materials such as aluminum alloy, high-strength steel, and SMC composite materials. It has multiple functions, including module fixing and support, collision impact protection, IP67 waterproof and dustproof rating, insulation and flame retardancy, and integrated liquid cooling thermal management. It is installed under the chassis of the vehicle and must meet stringent standards such as lightweighting, structural rigidity, corrosion resistance, and suppression of battery thermal runaway. It is a key integrated component to ensure the safe and stable operation of the power battery and improve the vehicle's range and collision safety performance.

[0003] When disassembling and repairing existing new energy vehicle battery boxes, it is necessary to unscrew the pipe at the coolant interface to drain the coolant. However, because it is not convenient to seal the interface for draining the coolant in existing new energy vehicle battery boxes, the unsealed interface during disassembly and repair allows external moisture and dust to enter the battery box, damaging the insulation performance of the box and increasing the risk of battery short circuit and thermal runaway.

[0004] In summary, the existing technology lacks a method for automatically sealing the coolant interface during the disassembly and maintenance of new energy vehicle battery boxes. Summary of the Invention

The top end of the sliding rod is rotatably connected to the other end of a connecting rod. A transmission shaft is fixedly connected to the bottom end of the sliding rod. A push-pull rod assembly is provided on one side of the transmission shaft. One end of the push-pull rod assembly is rotatably connected to the inner wall of the interface seat, and the other end of the push-pull rod assembly is rotatably connected to a movable frame. A groove is provided at the end of the push-pull rod assembly near the transmission shaft, and the inner wall of the groove is slidably fitted with the outer wall of the transmission shaft.

[0012] Preferably, the movable frame is U-shaped, with both ends of the movable frame slidingly engaging with the inner wall of the bottom opening of the interface seat.

At the same time, the surrounding gear is rotated, which, together with the fixed gear, drives the rotating frame to rotate, so that the sealing plug is aligned with the interface of the interface socket and inserted into the interface. No manual temporary sealing operation is required. The coolant interface is automatically sealed, which can effectively prevent dust and moisture from entering the battery box, protect the insulation performance of the internal cells and conductive components, and greatly improve the safety, cleanliness and maintenance efficiency of battery box disassembly, assembly and repair.

[0017] 2. By setting up a flow guiding component, while the moving cover moves the automatic sealing component out, the movable frame can be moved upward through the transmission component. At this time, under the action of the adjustment groove, the flow guiding groove will automatically rotate and move out, extending from below the interface of the interface seat. It can receive the coolant discharged during maintenance and guide the flow in a directional manner, effectively preventing the coolant from flowing along the surface of the battery box, avoiding coolant corrosion of the box, reducing coolant waste, simplifying maintenance operation steps, and improving the cleanliness and safety of maintenance operations.

[0018] 3. By setting a movable cover, the automatic sealing component and the flow guiding component can be retracted into the interface seat when not in use, which prevents dust from falling in and ensures that the automatic sealing component will not contaminate the inner wall of the interface seat when sealing. At the same time, it prevents the flow guiding component from contaminating it when guiding the coolant, further ensuring the sealing of the coolant interface. Attached Figure Description

Detailed Implementation

[0028] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] like Figures 1-8 The battery box for a new energy vehicle shown includes a battery box 1. An interface seat 2 is fixedly connected through one side of the battery box 1. A pipe connector 3 is threadedly connected to one side of the interface seat 2. A movable cover 4 is slidably fitted on the inner wall of the upper end of the interface seat 2. An automatic sealing component 5 is provided on the movable cover 4. A transmission component 6 is slidably fitted through the inner wall of the interface seat 2. A movable frame 7 is connected to one end of the transmission component 6. A flow guiding component 8 is rotatably connected to the movable frame 7. The automatic sealing component 5 includes a sliding frame 501. A sealing plug 502 is fixedly connected to one end of the sliding frame 501. The sealing plug 502 is movably inserted into the interface on the interface seat 2.

[0030] The sealing plug 502 is made of tapered rubber material at one end. The tapered end has a guiding and positioning function, which can be quickly aligned and inserted into the interface of the interface seat 2 without jamming. The rubber material has high elasticity, high sealing performance and corrosion resistance. It can fit tightly against the inner wall of the interface to achieve full circumference sealing, effectively blocking the intrusion of external moisture, dust and impurities. At the same time, it is suitable for acid and alkaline conditions of coolant, is not easy to age and deform, and ensures long-term interface sealing and protection performance.

[0031] By installing an automatic sealing assembly 5 inside the interface seat 2 of the battery housing 1, after the coolant is drained by removing the pipe joint 3 on the interface seat 2, the movable cover 4 is opened. Then, the electric push rod 504 drives the sealing plug 502 to move, which in turn drives the surrounding gear 506 to rotate. In conjunction with the fixed gear 505, the rotating frame 503 is driven to rotate, so that the sealing plug 502 is aligned with the interface of the interface seat 2 and inserted into the interface. No manual temporary sealing operation is required. The coolant interface is automatically sealed, which can effectively prevent dust and water vapor from entering the interior of the battery housing 1, protect the insulation performance of the internal cells and conductive components, and greatly improve the safety, cleanliness and maintenance efficiency of the battery housing 1 during disassembly, assembly and repair.

[0032] like Figure 4 As shown, a threaded rod 401 is rotatably connected through one side of the movable cover 4. A threaded sleeve 402 is threadedly connected to the outer wall of one end of the threaded rod 401. One end of the threaded sleeve 402 is fixedly connected to the inner wall of the interface seat 2.

[0033] A T-shaped rod 403 is fixedly connected to the side of the movable cover 4 facing the interface seat 2. A positioning sleeve 404 is slidably fitted on the outer wall of the T-shaped rod 403. A connecting rod 405 is rotatably connected to the other end of the T-shaped rod 403.

[0034] The connecting rod 405 enables the opening and closing of the movable cover 4, while simultaneously driving the flow guiding component 8 to retract and extend.

[0035] like Figure 5 As shown, a rotating frame 503 is slidably fitted on the outer wall of the sliding frame 501 away from the sealing plug 502. An electric push rod 504 is fixedly connected to the inner wall of the rotating frame 503. The other end of the electric push rod 504 is fixedly connected to the inner wall of the sliding frame 501. A pin is rotatably connected through the inner wall of the top of the rotating frame 503. The outer end of the pin is fixedly connected to the movable cover 4. A fixed gear 505 is fixedly connected to the inner end of the pin. A ring gear 506 is meshed and driven on one side of the fixed gear 505.

[0036] A universal joint 507 is fixedly connected to one end of the gear 506. The two ends of the universal joint 507 are rotatably connected to the inner wall of the rotating frame 503. The bottom end of the universal joint 507 extends through the inner wall of the rotating frame 503 to the outside and is fixedly connected to a transmission rod 508. A transmission groove 509 is provided on the outer wall of the transmission rod 508. The transmission groove 509 is composed of two parts: a spiral structure and a straight structure. A transmission sleeve 510 is fixedly connected to one end of the sliding frame 501. The transmission sleeve 510 extends through the inner wall of the rotating frame 503 to the outside and is slidably engaged with the outer wall of the transmission rod 508. The protrusion on the inner wall of the transmission sleeve 510 is slidably engaged with the inner wall of the transmission groove 509.

[0037] The spiral part of the transmission groove 509 enables the rotating frame 503 to rotate 180 degrees before the sliding frame 501 drives the sealing plug 502 to be inserted into the interface of the interface seat 2, so that the sealing plug 502 is aligned with the interface of the interface seat 2.

[0038] like Figure 6 As shown, the transmission assembly 6 includes a sliding rod 601, which is slidably fitted through the inner wall of the interface seat 2. The top end of the sliding rod 601 is rotatably connected to the other end of the connecting rod 405. The bottom end of the sliding rod 601 is fixedly connected to a transmission shaft 602. A push-pull rod assembly 603 is provided on one side of the transmission shaft 602. One end of the push-pull rod assembly 603 is rotatably connected to the inner wall of the interface seat 2, and the other end of the push-pull rod assembly 603 is rotatably connected to the movable frame 7. A groove 604 is provided at the end of the push-pull rod assembly 603 near the transmission shaft 602. The inner wall of the groove 604 is slidably fitted with the outer wall of the transmission shaft 602.

[0039] When the sliding rod 601 moves upward, it drives the push-pull rod assembly 603 to rotate and fold, thereby driving the movable frame 7 to move upward.

[0040] like Figure 3 , Figure 7 As shown, the movable frame 7 is U-shaped. Both ends of the movable frame 7 are slidably fitted with the inner wall of the bottom opening of the interface seat 2. Limiting grooves 701 are opened on the inner wall of both ends of the movable frame 7. A sponge pad is fixedly connected to the inner wall of the top of the interface seat 2. Adjustment grooves 201 are opened on both sides of the inner wall of the bottom opening of the interface seat 2. The bottom of the adjustment groove 201 is inclined and the upper end is straight. An arc-shaped guide vane is fixedly connected below the outer interface of the interface seat 2.

[0041] The curved guide vane helps to catch residual liquid, further preventing coolant from flowing down the casing.

[0042] The bottom of the adjustment groove 201 is inclined, which allows the flow guide 801 to rotate to a suitable angle before the movable frame 7 drives the flow guide component 8 to move up a small distance.

[0043] like Figure 8 As shown, the flow guiding component 8 includes a flow guiding groove 801, one end of which is fixedly connected to a rotating shaft 802. Both ends of the rotating shaft 802 are rotatably connected to the movable frame 7, and both ends of the rotating shaft 802 are fixedly connected to adjusting wheels 803.

[0044] The guide channel 801 is the core structure for receiving and guiding coolant. The channel structure can accurately collect and directionally discharge residual coolant, avoiding liquid splashing and overflow.

[0045] An adjusting rack 804 is provided on one side of the adjusting wheel 803 for meshing transmission. A limit block 805 is fixedly connected to the bottom end of the adjusting rack 804. The limit block 805 is slidably engaged with the inner wall of the limit groove 701. A guide wheel 806 is rotatably connected to one side of the adjusting rack 804. The outer wall of the guide wheel 806 is slidably engaged with the inner wall of the adjusting groove 201.

[0046] Working principle: When the equipment is running normally, the pipe joint 3 is connected to the external cooling pipe to realize the circulation and heat dissipation of the coolant; at this time, the movable cover 4 is in the closed state, and the automatic sealing component 5 and the flow guiding component 8 are completely housed inside the interface seat 2. The sponge pad inside the interface seat 2 achieves a sealed dustproof protection for the top of the flow guiding component 8, preventing external dust and impurities from adhering to the surface of the flow guiding groove 801.

[0047] When the battery box 1 needs maintenance or disassembly of the cooling pipes, firstly, rotate the threaded rod 401, and rely on the threaded sleeve 402 to drive the movable cover 4 to slide open. The movable cover 4 drives the T-shaped rod 403 and the connecting rod 405 to move synchronously, pulling the sliding rod 601 upward. The sliding rod 601 drives the transmission shaft 602 to slide along the slide groove 604, driving the push-pull rod group 603 to fold and rotate, lifting the movable frame 7 as a whole upward. During the upward movement of the movable frame 7, the guide wheel 806 slides along the inclined section at the bottom of the adjustment groove 201, driving the adjustment rack 804 to move laterally, meshing and driving the adjustment wheel 803 and the rotating shaft 802 to rotate, so that the guide groove 801 automatically flips and extends, accurately connecting to the bottom of the interface to form a directional guide channel. Then, rotate and loosen the pipe joint 3 to drain the residual coolant inside the pipe; receive the residual coolant discharged during maintenance.

[0048] After the coolant is drained, the electric actuator 504 extends, pushing the sliding frame 501 to move towards the interface. The sliding frame 501 drives the transmission sleeve 510 to move synchronously. The protrusion inside the transmission sleeve 510 slides along the spiral groove of the transmission rod 508, driving the transmission rod 508 and the universal joint 507 to rotate the surrounding gear 506. The surrounding gear 506 meshes and revolves around the fixed gear 505, driving the rotating frame 503 to rotate 180 degrees as a whole, completing the precise angle alignment of the sealing plug 502, ensuring that the sealing plug 502 is directly opposite the interface center of the interface seat 2.

[0049] After the angle alignment is completed, the electric push rod 504 continues to extend, and the transmission sleeve 510 slides smoothly along the straight section of the transmission groove 509, driving the sliding frame 501 and the sealing plug 502 to move forward in a straight line, so that the conical rubber structure sealing plug 502 is tightly inserted into the interface of the interface seat 2 to achieve a seal; it can effectively prevent external moisture, dust and impurities from entering the battery box 1, protect the insulation performance of the battery cell and electrical components, and eliminate safety hazards such as short circuits and moisture damage.

[0050] Before the maintenance work is completed and the pipe joint 3 is reconnected, the electric push rod 504 retracts, causing the sealing plug 502 to exit the interface and return to its original position; then the threaded rod 401 is rotated in the opposite direction, causing the movable cover 4 to close and return to its original position. The linkage transmission component 6 drives the movable frame 7 to move down, and the guide wheel 806 slides and returns to its original position along the straight section of the adjustment groove 201. The guide groove 801 automatically flips over and is stored inside the interface seat 2, completing the reset.
