Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to a device for testing the insertion and removal performance of automotive quick-swap battery sockets. Background Technology

[0002] Range anxiety is one of the pain points of pure electric vehicles. To address this issue, major OEMs are not only increasing the energy density and capacity of power batteries, but also racking their brains to shorten the recovery time after-sales service. Super-fast charging stations and fast battery swapping technology are currently two popular technologies for solving the range anxiety problem of electric vehicles.

[0003] Fast battery swapping technology refers to the direct replacement of the charged battery box of an electric vehicle with the one that has power, while the original battery box with low power is placed at a battery swapping station for charging.

[0004] During the quick swapping process, the battery swapping station needs to be equipped with a quick-connect socket to connect to the battery box and charge the swapped-out battery box. Quick swapping battery technology is one of the effective ways to solve the problem of slow charging of electric vehicles.

[0005] Because multiple quick-connections are required, higher demands are placed on quick-connect sockets. Therefore, it is necessary to conduct plug-in / plug-out tests on quick-connect sockets to determine their lifespan and other related performance characteristics, which will facilitate future maintenance and replacement.

[0006] Existing plug and socket insertion / removal tests are all routine tests, requiring manual adjustment of the insertion / removal angle. The automation level is low, and the insertion / removal test data also requires independent equipment or manual assistance to record and analyze, resulting in low efficiency and test accuracy.

[0007] Therefore, we propose a test device for the insertion and removal performance of automotive quick-swap battery sockets to solve the problems mentioned above. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-7 The present invention provides a technical solution: a test device for the insertion and removal performance of a car quick-swap battery socket, comprising: a chassis 8 and a computer control system, wherein a water supply system 7, the main body of the test device and the computer control system are installed inside the chassis 8;

[0032] The main body of the testing equipment includes a positioning mechanism 1, a left and right rotation mechanism 2, a front and back tilting mechanism 3, a translation mechanism 4, a lifting mechanism 5, a hoisting mechanism 6, and a water supply system 7;

[0033] The front and rear tilting mechanism 3 is fixedly installed on the fixed support plate 10, and the fixed support plate 10 is fixedly installed with the chassis 8.

[0034] The front and rear tilting mechanism 3 includes a tilting drive cylinder 31, a fixed plate 32, a support base 33, and a connecting piece 34. The fixed plate 32 is fixedly installed on the front surface of the fixed support plate 10. The tilting drive cylinder 31 is fixedly installed on the fixed plate 32 and the fixed support plate 10. The support base 33 is fixedly installed on the left and right sides of the front surface of the fixed plate 32. The connecting piece 34 is rotatably connected to the support base 33.

[0035] The clamp adjustment frame 9 is fixedly installed in the connector 34. The upper end of the clamp adjustment frame 9 is movably connected to the telescopic end of the tilting drive cylinder 31. The telescopic end is driven to extend and retract back and forth by the tilting drive cylinder 31, which in turn drives the upper end of the clamp adjustment frame 9 to move back and forth. The clamp adjustment frame 9 is rotated and tilted by the connector 34.

[0036] A lifting mechanism 6 is installed on the fixture adjustment frame 9. The lifting mechanism 6 includes a lifting servo motor 61, a lifting seat 62, and a lead screw 63. The lifting servo motor 61 is fixedly installed at the lower end of the fixture adjustment frame 9. The lifting servo motor 61 drives the lead screw 63. The lead screw 63 and the fixture adjustment frame 9 are provided with a lifting seat 62. The lifting seat 62 is threadedly rotatably connected to the lead screw 63. The lifting seat 62 is slidably connected to the guide column of the fixture adjustment frame 9.

[0037] The lifting servo motor 61 drives the lead screw 63 to rotate, so that the lifting seat 62 moves up and down within the clamp adjustment frame 9, thereby realizing the height adjustment of the lifting seat 62;

[0038] A left and right rotation mechanism 2 is installed on the lifting seat 62. The left and right rotation mechanism 2 includes a rotary servo motor 21, a fixed flange 22 and a rotary connector 23. The rotary servo motor 21 is fixedly installed on the lifting seat 62 through the fixed flange 22. The drive shaft of the rotary servo motor 21 is fixedly connected to the rotary connector 23. The rotary connector 23 is fixedly installed on the positioning mechanism 1.

[0039] The rotary servo motor 21 drives the rotary connector 23 to rotate the positioning mechanism 1 left and right.

[0040] Below the positioning mechanism 1 is a translation mechanism 4, which includes a Y-axis translation motor 41, an X-axis translation motor 42, an X-axis seat 43, and a Y-axis seat 44. The Y-axis seat 44 is fixedly installed on the working platform inside the chassis 8. The Y-axis translation motor 41, the Y-axis translation rail, and the Y-axis screw are installed on the Y-axis seat 44. The Y-axis translation motor 41 is driven by the Y-axis screw. The X-axis seat 43 is provided on the Y-axis translation rail and the Y-axis screw.

[0041] X-axis translation motor 42, X-axis translation rail and X-axis screw are installed on X-axis mount 43. X-axis translation motor 42 is driven by X-axis screw. Quick-change battery socket tray is installed on X-axis translation rail and X-axis screw.

[0042] The X-axis translation track and the Y-axis translation track are perpendicular to each other;

[0043] Y-axis translation motor 41 drives Y-axis screw to rotate, causing X-axis seat 43 to reciprocate along Y-axis translation track. X-axis translation motor 42 drives X-axis screw to rotate, causing quick-change battery socket tray to reciprocate along X-axis translation track, realizing automatic movement and position adjustment of quick-change battery socket tray on the plane. Screw rotation increases movement accuracy.

[0044] A concentric hole runs through the X-axis mount 43 and the Y-axis mount 44. A lifting mechanism 5 is installed in the hole. The lifting mechanism 5 is fixedly installed with the chassis 8 and fixedly connected with the quick-change battery socket tray. When the translation mechanism 4 moves the quick-change battery socket tray to the designated position, the lifting mechanism 5 lifts the quick-change battery socket tray to adjust the height of the quick-change battery socket tray.

[0045] The computer control system is connected to a PLC control module, which is electrically connected to the positioning mechanism 1, the left and right rotation mechanism 2, the front and back tilting mechanism 3, the translation mechanism 4, the lifting mechanism 5, the hoisting mechanism 6, and the water supply system 7.

[0046] Positioning mechanism 1 accurately positions the quick-change battery socket. Left and right rotation mechanism 2 rotates positioning mechanism 1 left and right to make its rotation angle with the quick-change battery meet the insertion and removal requirements. Forward and backward tilting mechanism 3 rotates positioning mechanism 1 forward and backward to make it form a corresponding forward and backward tilting angle with the quick-change battery socket. Translation mechanism 4 is used to adjust the quick-change battery socket to different positions to realize insertion and removal tests at different positions. Lifting mechanism 6 is used to lift positioning mechanism 1 to lower the quick-change battery socket to the test approach point to complete the preparation work. Water supply system 7 is used to test the actual flow rate and pressure resistance level inside the quick-change battery socket by supplying water during the insertion and removal test.

[0047] Water supply system 7 supplies water to the quick-change battery socket. Water is pumped from water tank 46 by water pump 45 and supplied to the quick-change battery socket through pipeline. Pressure sensor 47 detects the pressure at the inlet and outlet to obtain the internal pressure difference of the quick-change battery socket during the insertion and removal process. Flow meter 48 monitors whether the flow rate inside water supply system 7 meets the test standard. The flow rate can be adjusted by adjusting the power of water pump 45 or by inputting the required flow rate value through PLC analog output.

[0048] The working principle of the servo mechanism of the insertion and removal test machine: The cooling water pipe connector is manually inserted into the positioning mechanism 1 and the start button is pressed. The equipment lowers the lifting mechanism 6 to the designated insertion and removal origin point through the translation mechanism 4 and the lifting mechanism 5. The lifting mechanism 5 drives the quick-change battery socket to perform continuous insertion and removal. The left and right rotation mechanism 2 and the front and back tilt mechanism 3 move to the required test position through the one-key return to origin function. The bottom lifting electric cylinder drives the clamp to complete the durability test of continuous insertion and removal of the cooling water pipe connector. At the same time, the water supply system 7 starts to work.

[0049] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
