Description

Technical Field

[0001] The present invention relates to the technical field of new energy battery modules, and in particular to a new energy battery module. Background Art

[0002] The new energy battery module is an important part of the battery management system of electric vehicles. Its main task is to ensure that the battery pack works within a safe range, provide the necessary information required for vehicle control, and respond and handle abnormalities in a timely manner. At the same time, it will also determine the battery charging and discharging power based on factors such as ambient temperature, battery status and vehicle demand. The new energy battery module is generally connected by multiple batteries. The lithium battery module PACK is one of the important components in the lithium battery manufacturing process. It is usually composed of multiple battery cells (monomers) and interconnected by cables or plate connectors. Each battery cell contains components such as positive electrode, negative electrode, diaphragm and electrolyte. After the battery cells are assembled, they are connected in series or in parallel through plate connectors or cables to form a module, and then fixed with insulating tape or other materials, and finally connected to other modules or external devices.

[0003] New energy battery modules are generally installed at the bottom of the car. When the car is moving, the different road conditions on the ground cause the car to bump around, and when the car bumps around, the various battery cell connectors may be deformed or damaged due to vibration. Damage or deformation of the battery cell connectors may cause an internal short circuit in the battery, leading to serious consequences such as battery overheating or even fire. Improvements need to be made to this problem.

[0004] Therefore, it is necessary to design a new energy battery module that is highly practical and ensures the safety performance of the new energy battery module. Summary of the invention

[0005] The purpose of the present invention is to provide a new energy battery module to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a new energy battery module, comprising a battery module protective shell, a buffer protection mechanism, a stabilizing mechanism and a fixing mechanism, a battery cell is arranged at the bottom of the battery module protective shell, a pressure detector is fixedly connected to the middle of the top left side of the battery module protective shell, a limiting pressure sheet is fixedly connected to the left side of the battery module protective shell, a positive and negative electrode connector is arranged on the top of the battery cell, and a battery cell connector is welded on the outside of the positive and negative electrode connectors.

[0007] Wherein, the buffer protection mechanism comprises:

[0008] The protective block is fixedly connected to the left side of the top of the battery module protective shell and is located on the rear side of the top of the battery module protective shell. The top of the battery cell connector is fixedly connected to a protective connecting rod, and the top of the protective connecting rod is fixedly connected to a lifting piston disk. The outer side of the lifting piston disk is rotatably connected to a lifting sliding wheel, and the inner wall of the protective block is fixedly connected to a friction pad.

[0009] According to the above technical solution, the stabilizing mechanism includes a driving sleeve, a fixed plate, an electric lifting rod, a lifting sleeve plate, a lifting plate frame, a spring and a clamping pad. The driving sleeve is fixedly connected to the left side of the top inside the battery module protective shell, the fixed plate is fixedly connected to the bottom of the driving sleeve, the electric lifting rod is fixedly connected to the top inside the driving sleeve, the lifting sleeve plate is fixedly connected to the bottom of the electric lifting rod, the lifting plate frame is fixedly connected to the middle of the front side of the lifting sleeve plate, the spring is fixedly connected to the back side of the lifting plate frame, and the clamping pad is fixedly connected to the rear end of the spring.

[0010] According to the above technical solution, the fixing mechanism includes an air storage bag, an adjusting box, a connecting pipe, a pressure spring, a piston plate, an extrusion rod and an extrusion positioning groove. The air storage bag is fixedly connected to the left side of the top of the fixing plate, the adjusting box is fixedly connected to the rear side of the top of the battery module protective shell and is located on the right side of the protective block, the connecting pipe is fixedly connected to the top of the right side of the adjusting box, the pressure spring is fixedly connected to the top inside the adjusting box, the piston plate is fixedly connected to the bottom end of the pressure spring, the extrusion rod is fixedly connected to the middle of the bottom of the piston plate, and the extrusion positioning groove is fixedly connected to the bottom of the extrusion rod.

[0011] According to the above technical solution, damping oil is arranged in the protective block, the lifting piston disc is slidably connected to the inner wall of the friction pad through the lifting sliding wheel, and a circular groove is opened on the top of the lifting piston disc, so that the lifting piston disc can move in the protective block. By setting the damping oil, the damping oil can flow in the circular groove on the lifting piston disc.

[0012] According to the above technical solution, a lifting groove is opened on the top of the lifting sleeve, and the lifting sleeve is slidably connected to the outer side of the driving sleeve through the lifting groove. Pressure plates are fixedly connected to the tops of the left and right sides of the back side of the lifting plate frame, so that the electric lifting rod can control the lifting sleeve to lift and lower on the outside of the driving sleeve.

[0013] According to the above technical solution, the bottom end of the extrusion rod passes through the bottom inner wall of the adjustment box and extends to the bottom of the adjustment box to be fixedly connected to the extrusion positioning groove, so that the extrusion rod can drive the extrusion positioning groove to move.

[0014] According to the above technical solution, the connecting tube is connected to the bottom left side of the air storage bag at one end away from the regulating box, a sensing patch is provided at the bottom of the limiting pressure plate, and the pressure detector is electrically connected to the limiting pressure plate. By providing the sensing patch at the bottom of the limiting pressure plate, the pressure can be detected.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: in the present invention, when the vehicle is bumpy, the inside of the battery module protective shell vibrates and shakes, causing the battery cell connector on the battery cell to shake. At this time, the induction patch at the bottom of the limit pressing piece detects the upward force generated by the battery cell. When the detection result is that the vibration is small, the battery cell connector will vibrate through the protective connecting rod to drive the lifting piston disk to lift and lower on the protective block. At the same time, the lifting sliding wheel on the lifting piston disk slides on the inner wall of the friction pad in the protective block. At the same time, the damping oil in the protective block flows in the circular groove on the lifting piston disk, which can increase the resistance of the lifting piston disk during the overall movement, and then convert the shaking into the friction force when the lifting piston disk moves. By increasing the friction force, the force generated during shaking can be reduced, thereby reducing the impact of the battery cell shaking on the battery cell connector;

[0016] When the sensing patch at the bottom of the limit pressing piece detects a large shaking force, the electric lifting rod in the driving sleeve is controlled to work, so that the electric lifting rod controls the lifting sleeve plate to move up and down outside the driving sleeve during operation, so that the lifting plate frame can be moved from above the fixed plate to below the fixed plate. At this time, the spring elastically rebounds, so that the clamping pad is pressed against the front and back of the battery cell connector, and the middle of the front and back of the battery cell connector can be clamped to avoid excessive vibration and deformation of the middle of the battery cell connector due to shaking;

[0017] When the shaking amplitude is large, the pressure plate is controlled to move downward when the lifting sleeve moves downward, so that the pressure plate moves downward and squeezes the air bag, so that the air in the air bag is filled into the top of the regulating box through the connecting pipe, so that the pressure at the top of the regulating box is increased, and the pressure spring is stretched. At the same time, the extrusion positioning groove on the extrusion rod at the bottom of the piston plate is pressed against the left side of the top of the battery cell connector, so that the battery cell connector can be reinforced and stabilized as a whole when the shaking amplitude is large, to prevent the battery cell connector from being damaged due to deformation due to the large shaking amplitude.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-4 The present invention provides a technical solution: a new energy battery module, including a battery module protective shell 1, a buffer protection mechanism 7, a stabilizing mechanism 8 and a fixing mechanism 9, a battery cell 2 is arranged at the bottom of the battery module protective shell 1, a pressure detector 3 is fixedly connected to the middle of the top left side of the battery module protective shell 1, a limited position pressing sheet 4 is fixedly connected to the left side of the battery module protective shell 1, a positive and negative electrode connector 5 is arranged on the top of the battery cell 2, and a battery cell connector 6 is welded on the outside of the positive and negative electrode connector 5.

[0029] Wherein, the buffer protection mechanism 7 comprises:

[0030] The protective block 701 is fixedly connected to the left side of the top of the battery module protective shell 1 and is located at the rear side of the top of the battery module protective shell 1. The top of the battery cell connector 6 is fixedly connected to a protective connecting rod 702. The top of the protective connecting rod 702 is fixedly connected to a lifting piston disk 703. The outer side of the lifting piston disk 703 is rotatably connected to a lifting sliding wheel 704. The inner wall of the protective block 701 is fixedly connected to a friction pad 705.

[0031] Damping oil is arranged in the protective block 701, and the lifting piston disc 703 is slidingly connected to the inner wall of the friction pad 705 through the lifting sliding wheel 704. A circular groove is opened on the top of the lifting piston disc 703, so that the lifting piston disc 703 can move in the protective block 701. By setting the damping oil, the damping oil can flow in the circular groove on the lifting piston disc 703.

[0032] When the vehicle is bumpy, the battery module protective shell 1 vibrates and shakes, causing the battery cell connector 6 on the battery cell 2 to shake. At this time, the sensing patch at the bottom of the limiting pressure plate 4 detects the upward force generated by the battery cell 2. When the detection result is that the vibration is small, the battery cell connector 6 will vibrate through the protective connecting rod 702 to drive the lifting piston plate 703 to rise and fall in the protective block 701. At the same time, the lifting sliding wheel 704 on the lifting piston plate 703 slides on the inner wall of the friction pad 705 in the protective block 701. At the same time, the damping oil in the protective block 701 flows in the circular groove on the lifting piston plate 703, which can increase the resistance of the lifting piston plate 703 during the overall movement, and then convert the shaking into the friction force when the lifting piston plate 703 moves. By increasing the friction force, the force generated during the shaking can be reduced, thereby reducing the impact of the battery cell 2 on the battery cell connector 6 when it shakes.
