Description

Technical Field

[0001] The present invention relates to the field of battery pack installation, and more specifically, to a new energy vehicle battery installation structure and method. Background Art

[0002] The battery pack of new energy vehicles is one of the core components in the power system of electric vehicles. It is responsible for storing and supplying electrical energy to drive the motor. The design of the battery pack involves multiple aspects such as battery cells, battery management system (BMS), thermal management system, structural support, etc.

[0003] The installation structure of the battery pack mainly focuses on how to fix the battery pack to the vehicle's body structure while ensuring the safety, stability and maintenance convenience of the battery pack. The battery pack is generally installed in the middle or bottom of the vehicle chassis. This can lower the center of gravity of the vehicle and improve driving stability. The battery pack is usually equipped with a connector on the periphery to dock with the vehicle chassis and then fixed with multiple bolts.

[0004] Vehicle battery packs are usually designed to operate stably for a long time, but in some cases they need to be disassembled for maintenance, inspection or replacement. Battery pack disassembly generally occurs in cases of battery failure or unit damage, battery management system failure, reduced charge and discharge performance, battery pack damage, etc. The general steps for disassembly and assembly are as follows:

[0005] Disassembly of the battery pack: lift the vehicle and move the dedicated transfer vehicle under the battery pack. The transfer vehicle is equipped with a lifting mechanism. After it is lifted up, it is supported at the bottom of the battery pack. Remove the connecting bolts between the battery pack and the chassis, and lower the transfer vehicle to take out the battery pack.

[0006] Installation of the battery pack: When the vehicle is lifted, the battery pack is moved to the bottom of the chassis by the transfer vehicle. The transfer vehicle lifts the battery pack and docks it with the chassis. At this time, the staff connects the bolts in sequence and then tightens all the bolts according to the specified torque.

[0007] During the installation and removal of the battery pack, it takes a certain amount of time because there are many bolts. During this process, the entire battery pack needs to be supported by the lifting mechanism of the transfer vehicle. The battery pack is heavy, and the reliability of the lifting mechanism alone is poor. Once fatigued or damaged, the battery pack will fall or bump, which will cause great losses or damages;

[0008] Secondly, in order to reduce the impact of vibrations during driving on the battery pack, a shock absorption system is usually designed. There may be elastic rubber gaskets or shock absorbers between the battery pack and the frame to absorb external shocks and vibrations. However, the traditional shock absorption system is installed independently, which is costly, occupies a large space, and is heavy, which is not conducive to the lightweight design of the vehicle.

[0009] In order to solve the above problems, this application proposes a new energy vehicle battery installation structure and method. Summary of the invention

[0010] The purpose of the present invention is to provide a new energy vehicle battery installation structure and method, which solves the problems in the prior art by sharing the weight of the battery pack with the vehicle lift during disassembly and assembly and combining the installation and shock absorption of the battery pack with the chassis.

[0011] The purpose of the present invention can be achieved through the following technical solutions:

[0012] A new energy vehicle battery installation structure and method, comprising a battery pack to be installed and a mounting seat fixed to a vehicle chassis and located above the battery pack, and further comprising:

[0013] A connecting seat forming a shock absorbing platform and having a shock absorbing cavity inside, wherein the connecting seat is distributed outside the battery pack and is located directly below the mounting seat;

[0014] A shock-absorbing sheet disposed at the lower part of the connecting seat and serving as a shock-absorbing member;

[0015] A movable component elastically connected to the inner cavity of the connecting seat through a shock-absorbing sheet, and the movable component is also detachably connected to the connecting seat, and the movable component is located directly below the mounting seat;

[0016] A locking component that penetrates the movable component from top to bottom and fixes it to the mounting seat, wherein the locking component uses a threaded structure to connect the movable component and the mounting seat, and there are at least two sets of locking components under each mounting seat;

[0017] A locking component is arranged on the locking component and quickly limits or disengages the movable component from the mounting seat by eccentric rotation;

[0018] In the above scheme, a connecting seat, a movable part, and a locking part are sequentially arranged at the connection between the battery pack and the mounting seat. The connecting seat is detachable to facilitate the assembly and maintenance of the movable part, and the movable part is detachable to facilitate maintenance and replacement. The locking part fixes the movable part and the mounting seat in a threaded manner. The structure is simple and reliable. There is a movable space between the connecting seat and the movable part, and a shock-absorbing plate is provided to form a shock-absorbing effect between the battery pack and the chassis. The locking part is provided with a locking part, which cooperates with the movable part to achieve a rapid locking effect, thereby providing support for the battery pack when the locking part is not completely removed, thereby preventing the battery pack from tilting or falling due to a long-term heavy load on the transfer vehicle, thereby further improving safety.

[0019] The connecting seat comprises:

[0020] A fixing base fixed horizontally on the side of the battery pack;

[0021] A fixing cover is docked at the front end of the fixing seat and assembled with it by threads. The fixing seat and the fixing cover form a closed space for the installation and elastic movement of the movable parts. To ensure the support stability, the connecting seat is made of high-strength metal as a whole. The fixing seat is fixed to the side of the battery pack by welding or bolts. A detachable fixing cover is provided to facilitate the assembly, maintenance, replacement and other operations of the movable parts.

[0022] A semicircular bevel groove formed on the upper inner end of the fixing seat and the fixing cover;

[0023] An installation groove is provided at the lower inner end of the fixing seat and the fixing cover and is used for installing the shock-absorbing plate. An annular groove with a "V"-shaped cross-section is formed between the semicircular inclined groove and the shock-absorbing plate. A gap is left between the annular groove with a "V" cross-section and the movable part and they are connected by steel balls, providing shock-absorbing activity space in multiple directions.

[0024] The movable parts include:

[0025] Two movable plates are arranged symmetrically up and down and fixed integrally by bolts, and the outer circumferential ring of the movable plate is provided with inclined surfaces which are respectively parallel to the lower surface of the semicircular inclined groove and the upper surface of the shock-absorbing plate; a plurality of movable grooves are circumferentially distributed in the movable plate and correspond to each other up and down, and the movable parts are set as a detachable structure as a whole, which is convenient for replacement after partial damage, and also convenient for assembly and other work;

[0026] At least two connecting holes are provided through the movable piece, and the locking member passes through the connecting holes and connects the movable member and the mounting seat;

[0027] The steel ball is movably arranged in the movable groove, and the upper and lower ends of the steel ball both protrude from the movable plate and contact with the lower surface of the semicircular inclined groove and the upper surface of the shock-absorbing plate respectively. When the battery pack and the vehicle are stationary, the lower end of the steel ball will not be squeezed with the shock-absorbing plate, thereby ensuring durability.

[0028] The locking component comprises:

[0029] A connecting pin vertically fixed to the bottom of the mounting seat, the connecting pin passes through the movable sheet from top to bottom, and the connecting pin passes through and is inserted into a connecting hole in the movable sheet;

[0030] A threaded portion is fixed to the penetrating portion at the lower end of the connecting pin; a connecting sleeve is provided at the lower end of the threaded portion, which connects the movable component to the mounting seat through a thread, and the thread is used for final locking to ensure the reliability of the connection between the movable component and the mounting seat, thereby ensuring the stability of the battery pack installed on the vehicle chassis.

[0031] The connecting sleeve comprises:

[0032] A compression sleeve at the top, after the connecting sleeve is tightened, the compression sleeve is supported on the bottom of the movable sheet and the mounting seat is close to the top of the movable sheet; a thread groove located in the middle and matched with the thread of the connecting sleeve; a polygonal block located at the bottom;

[0033] In the above technical solution, after the threaded portion and the thread groove are locked as shown in the figure, the clamping sleeve is supported on the bottom of the movable piece, thereby locking the movable part with the mounting seat without affecting the use of the locking part, and the polygonal block is used in conjunction with the tool to twist the connecting sleeve.

[0034] The locking component comprises:

[0035] The eccentric column formed between the connecting pin and the threaded part is provided with an eccentric column eccentric to the threaded part. When the eccentric column is reset, it can be integrated into the connecting pin without affecting the connection of the connecting sleeve. When eccentric, it can form a quick lock on the locking component, so that the movable component and the mounting seat are still in a connected state after the connecting sleeve is detached, thereby ensuring safety.

[0036] The limiting roller horizontally moves in the eccentric column and is elastically connected by the limiting spring. The limiting roller and the limiting spring cooperate with the limiting groove to accurately locate the rotation position of the locking sleeve, thereby ensuring the reliability of the cooperation between the structures.

[0037] The locking sleeve is rotated on the outside of the eccentric column. The outer diameter of the locking sleeve is equal to that of the connecting pin. By setting the diameters equal, the locking sleeve can be rotated into the connecting pin, thereby not affecting the final locking of the locking component.

[0038] The eccentric column is provided with a movable hole for accommodating the limiting roller and the limiting spring and having one end being open;

[0039] In the above technical solution, the limiting roller and the limiting spring are both located in the movable hole, and the limiting roller is engaged with the limiting groove through the limiting spring.

[0040] The inner side wall of the locking sleeve is provided with two limiting grooves which are distributed in a circumference and cooperate with the limiting roller;

[0041] In the above technical solution, two limit grooves are arranged to cooperate with the limit rollers. When one of the limit grooves is engaged with the limit roller, the locking sleeve and the connecting pin are in a coaxial state, which does not affect the docking between the connecting sleeve and the threaded part. When the other limit groove is engaged with the limit roller, the locking sleeve and the connecting pin are eccentric and stuck at the bottom of the movable plate, thereby playing a limiting role.

[0042] The outer side wall of the locking sleeve is provided with a rotation groove inwardly for facilitating the locking sleeve to be twisted along the eccentric column;

[0043] In the above technical solution, the rotating groove increases the friction force when the locking sleeve is rotated, and also facilitates the separation of the limiting roller and the limiting groove.

[0044] The locking sleeve is covered by the compression sleeve when it is concentric with the connecting pin, and the top part contacts the bottom part of the movable sheet when it is eccentric;

[0045] In the above technical solution, the locking component is integrated into the connecting pin, so that it can be stuck at the bottom of the movable plate through eccentric rotation when needed. At this time, due to the contact between the top of the locking sleeve and the movable plate, the battery pack, the connecting seat, and the movable component cannot move downward, ensuring safety during disassembly and assembly.

[0046] A method for installing a new energy vehicle battery comprises the following steps:

[0047] S1. Lift the vehicle with a lift, place the battery pack accurately on a dedicated transfer vehicle, and move the transfer vehicle carrying the battery pack to the bottom of the vehicle chassis;

[0048] S2. The transfer vehicle drives the battery pack to rise and docks all the locking components. At this time, the locking components on the locking components are opened. After the locking components are opened, the battery pack is quickly connected to the movable components.

[0049] S3. Lock the locking components in sequence, and reset the locking components on the corresponding locking components before locking, until all the locking components are locked and the installation is completed.

[0050] Beneficial effects of the present invention:

[0051] The present invention provides a locking component on the connecting pin. When the locking component is disengaged, the locking sleeve can be rotated to clamp the connecting pin and the movable component, thereby playing a quick buckle role. Combined with the actual disassembly and assembly of the battery pack, the battery pack is supported by the transfer vehicle while being hung on the chassis through the action of the locking component, sharing the load weight of the transfer vehicle during the disassembly and assembly process. Then, the locking component is disengaged after all the locking components are disengaged, thereby reducing the load of the transfer vehicle and improving durability and safety. Moreover, even if the transfer vehicle fails, the locking component can be used to prevent the battery pack from falling, shortening the time for the transfer vehicle to fully support the weight of the battery pack, thereby reducing the probability of accidents.

[0052] The present invention arranges a movable part inside the connecting seat, and the movable part cooperates with the shock-absorbing plate to achieve a flexible buffering effect. In a static state, the steel ball contacts the semicircular inclined groove, and does not cause continuous fatigue of the shock-absorbing plate, so the durability is higher. At the same time, the semicircular inclined groove and the inner inclined surface of the shock-absorbing plate can achieve self-resetting and damping effects, and will not continue to swing after being subjected to force.

[0053] The present invention adopts threaded locking for the locking component to ensure the stability of the battery pack after installation, and then arranges the locking component on the movable component to combine the installation and removal and shock absorption between the battery pack and the mounting seat, with higher structural coordination. Compared with an independent shock absorption system, it has low cost and light weight, which is beneficial to the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS
