Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle battery maintenance equipment, and specifically to a new energy vehicle battery maintenance equipment. Background Art

[0002] As the core component of the whole vehicle, the safety protection system of the power battery of new energy vehicles faces severe challenges under complex working conditions. Although the current mainstream lithium iron phosphate and ternary lithium battery packs each have advantages in terms of energy density, they both have significant structural safety risks. Especially when driving on unpaved roads, the deformation of the battery pack box caused by chassis bumps has become a major safety hazard.

[0003] Due to the lack of real-time deformation monitoring devices in the current technical standards, some battery pack damage events show characteristics of hidden damage. Such damage usually appears as micron-level cracks (50 - 200 μm). Before causing electrolyte leakage, there is neither abnormal voltage nor temperature change, making it difficult for more than 90% of drivers to detect. The current maintenance system relies on the passive protection mode of regular inspections, resulting in an average discovery period of up to 32 days for such hidden damage (according to industry statistics).

[0004] In the maintenance workshop scenario, there are multiple risks superimposed in the chassis maintenance operation: 1) Under the condition of the lift, the battery pack bears additional prestress; 2) The probability of accidental collision of maintenance tools increases; 3) The probability of contact with metal dust increases. More notably, when maintenance personnel focus on dealing with the suspension system or braking system, most of the attention resources are occupied by regular maintenance items, and the visual inspection coverage rate of the bottom guard plate of the battery pack is generally insufficient. If the electrolyte leaks slowly through the microcracks at this time (0.1 - 0.5 ml / min) and encounters the electric spark generated by the maintenance equipment, the ternary lithium battery can complete the transformation from thermal runaway to deflagration within 0.8 seconds, with a heat release rate as high as 5 MW / s, far exceeding 1.2 MW / s of the lithium iron phosphate battery. Summary of the Invention

[0005] The purpose of the present invention is to provide a new energy vehicle battery maintenance equipment to solve the problems mentioned in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A new energy vehicle battery maintenance equipment, including a lifting column, on which a lifting arm and a maintenance arm are provided, and the lifting arm is located directly above the maintenance arm;

[0008] A chute plate is provided at the outer end of the maintenance arm, and the protection plate is installed inside the chute plate;

[0009] The protective plate includes a protective plate and a bottom plate. The protective plate is arranged on the bottom plate, and a lighting lamp is arranged on the bottom plate.

[0010] Preferably, the lifting arm includes a base and a support arm. The base is installed in the lifting column and can be driven by the lifting column to move up and down. The support arm is connected to the base through a connecting shaft.

[0033] A chute plate 311 is provided at the outer end of the maintenance arm 31, the protective plate 32 is installed inside the chute plate 311, and the chute plate 311 is used to drive the protective plate 32 to move back and forth along the chute direction inside the chute plate 311;

[0034] The protective plate 32 includes a protective plate 321 and a bottom plate 322. The protective plate 321 is disposed on the bottom plate 322. A lighting lamp 323 is provided on the bottom plate 322. The light of the lighting lamp 323 helps maintenance personnel to conduct a detailed inspection of the battery.

[0035] In this embodiment, the lifting arm 2 includes a base 21 and a support arm 22. The base 21 is installed in the lifting column 1 and can be driven by the lifting column 1 to move up and down. The support arm 22 is connected to the base 21 through a connecting shaft 23. The support arm 22 can rotate around the connecting shaft 23 to increase its effective working range.

[0036] In this embodiment, the chute plate 311 is installed on the clamping plate 312. The clamping plate 312 is fixedly installed on the fixed seat 313. The clamping plate 312 is used to provide support for the chute plate 311.

[0037] In this embodiment, the fixed seat 313 is installed on the lifting column 1, so that the fixed seat 313 can be driven by the lifting column 1 to move up and down.

[0038] In this embodiment, an electric slide rail is provided in the chute plate 311. The electric slide rail is electrically connected to the contact switch 33. The electric slide rail can be started and stopped through the contact switch 33. The protective plate 32 can move back and forth driven by the electric slide rail.

[0039] In this embodiment, a sliding block 315 is provided inside the chute plate 311. A laser detector 316 is provided above the sliding block 315. The laser detector 316 can detect whether there are foreign objects on the surface of the protective plate 32 through laser. For foreign objects falling on the protective plate 32, they can be detected in time by the laser detector 316 and maintenance personnel can be reminded, so that the electrolyte leakage phenomenon caused by liquid leakage can be detected in time and the resulting danger can be reduced. When necessary, professional sensors such as interdigital electrode sensors can also be provided on the protective plate 32 to detect whether there is electrolyte dripping.

When performing a detailed inspection from one end of the battery to the other end, such as inspecting the battery in the direction from the front end to the rear end of the vehicle, when the personnel need to move after completing the inspection at the front end and face the rear end of the battery, at this time, the contact switch 33 located in front of the personnel is pressed, so that the protective plate 32 and the inspection hole 324 move backward slowly. At this time, the personnel move along with the inspection hole 324 until they move to a suitable position. During this process, after the contact switch 33 arranged on the rear side of the moving direction of the personnel is touched, that is, when both the front and rear contact switches 33 are activated, the movement of the protective plate 32 will stop, which can prevent the personnel from being pushed down.

[0042] In this embodiment, the length of the inspection arm 31 is greater than the length of the protective plate 32, and the distance from the inspection hole 324 to any side edge at both ends of the inspection arm 31 can meet the requirements for battery inspection, that is, the moving distance of the inspection hole 324 can meet the detection requirements in the length direction of the battery.

[0043] In this embodiment, a smoke alarm is provided on the protective plate 321, which can timely remind the personnel to evacuate and reduce risks when the personnel are performing inspections and do not notice the specific state of the battery.

[0044] Working principle: When in use, first lift the vehicle to a suitable inspection height through the lifting arm 2, and then lift the protective plate 32 to a suitable height. At this time, control the inspection hole 324 to be located at any end of the battery, and the person's head passes through the inspection hole 324 to perform the battery inspection work with the cooperation of the lighting lamp 323. After completing one place, move the inspection hole 324 to perform the inspection at the next position until the inspection is completed. During this process, the protective plate 32 can detect whether there is battery leakage.
