Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a battery transport protection device and a use method thereof. Background Art

[0002] In the electric vehicle industry, batteries are typically large and heavy, so many problems arise during testing, transportation, and handling, such as the load-bearing and stacking issues of the entire battery during transportation; battery transportation issues during production line logistics and inventory stacking space issues; and battery pack abnormalities during testing require immediate relocation to a location away from the workshop where the abnormality occurred.

[0003] The battery transfer device is an auxiliary device used in battery production and transportation. It can quickly and easily transfer batteries, ensuring that the batteries do not bump or slip during the transfer process, effectively ensuring the safety of battery transfer, improving battery transfer efficiency, and solving the above-mentioned problems. As battery transfer equipment, it is necessary to have certain shock absorption and collision prevention capabilities. Current transfer equipment is basically improved around these two aspects.

[0004] For battery packs with test abnormalities, not only must they meet the general requirements for shock absorption and collision protection during transportation, but they must also guard against unexpected situations that may arise during transportation, such as abnormally high temperatures. If the battery itself is in an abnormal state during transportation, causing internal heat to rise continuously, or if it is exposed to high temperatures during long-distance transportation, the test battery will have certain safety hazards, which may manifest as fire or even explosion. Therefore, a transfer device dedicated to test batteries is needed to reduce potential safety hazards. Summary of the Invention

The box cover group 7 is mounted on the upper side of the secondary box group 3, and the various structures are fixed by the locking screw 6 after adjusting the mounting height. The battery pack limiting component 4 is arranged inside the main box group 2 and the secondary box group 3, and is used to limit the two ends of the battery pack. The box limiting component 5 is arranged on the four sides of the main box group 2 and the secondary box group 3.

The moving wheel group 9 is fixed at the bottom of the base frame 1.

[0034] The main box group 2 is composed of a main support frame 21 and four main movable box panels 22, wherein the main movable box panels 22 are hinged on the four sides of the base frame 1, and form a box-type structure with the support frame 21. The upper end of the main support frame 21 is a hollow structure and several first fixing holes 211 are opened on both sides, and the size of the first fixing hole 211 matches the size of the locking screw 6. A first connecting groove 221 is opened on the upper end of the main movable box panel 22, and the whole can rotate around the bottom.

[0039] The box limit assembly 5 is composed of an inner limit block 51, an outer limit seat 52 and an outer limit block 53, wherein the inner limit block 51 is installed on the four sides of the main support frame 21 and the secondary support frame 31, and is used to limit the main movable box plate 22 and the secondary movable box plate 32 from flipping inward. The outer limit seat 52 is fixed on the four outer peripheries of the main support frame 21 and the secondary support frame 31, and is provided with a curved groove to cooperate with the outer limit block 53. The outer limit block 53 is embedded in the curved groove of the outer limit seat 52 after the main movable box plate 22 and the secondary movable box plate 32 are surrounded into a box body to prevent it from flipping outward during transportation.

[0040] The box cover assembly 7 comprises a top frame 71, a top plate 72, four hanging rods 73, and a hanging curtain. The top plate 72 is fixed to the top frame 71, the four hanging rods 73 are fixed around the top frame 71, and the hanging curtain is hung on the hanging rods 73. It should be noted that the lower end of the top frame 71 flexibly matches the hollow structure at the upper end of the secondary support frame 31 and is provided with a hole that matches the second fixing hole 311. It is tightened and fixed by the locking screw 6. The hanging curtain is provided to cover the gap in the lower side of the secondary box assembly 3 and can be made of insulating material to isolate it from the outside world.

[0041] The refrigeration module 8 includes a refrigeration box 81, an air supply pipe 82, an air exhaust pipe 83 and a temperature sensing module arranged inside each box, wherein the refrigeration box 81 is arranged on the top plate 72, and one end of the air supply pipe 82 and the air exhaust pipe 83 are connected to the two sides of the refrigeration box 81, and the other end is connected to the main box group 2 and the secondary box group 3, and a number of air holes 84 are arranged on the surface.

[0042] The specific implementation methods are as follows:

[0043] S1. Battery pack loading: Open the main movable box panels 22 around the main box group 2 and transfer the abnormal test battery to the shock absorbing plate 41;

[0044] S2, limit: rotate the rotation handles 45 on both sides to press the limit pads 46 against both sides of the battery pack;

[0045] S3, closing: After the limit is completed, the four main movable box panels 22 are erected and the outer limit blocks 53 are inserted to form an upward-opening box body;

[0046] S4. Sub-box installation: If multiple battery packs need to be transported, stack the sub-boxes on top of the main box.

[0047] S5, erecting the box cover: after the overall erection is completed, assemble the box cover group 7;

[0048] S6. Refrigeration module installation: Fix the refrigeration box 81 on the box cover group 7, and introduce the air supply pipe 82 and the air extraction pipe 83 into the main box group 2 and the secondary box group 3;

[0049] S7. Transportation: After all the structures are erected, move the whole structure to the designated location;

[0050] S8. Status monitoring: Monitor the temperature inside each box at all times during transportation. If the temperature reaches the warning level, perform emergency cooling.

[0051] Specifically, the battery pack limiting assembly 4 in S1 and S2 has a shock-absorbing and anti-collision effect on the battery pack as a whole. The shock-absorbing plate 41 reduces the vibration of the battery pack during transportation, and the limiting cushion 46 limits the displacement of the battery pack to avoid internal collision.

[0052] The sealing treatment in S3, S4 and S5 is mainly to block air circulation with the outside and to block high temperature and sun protection, so as to avoid the impact of long-distance transportation in high temperature environment on the internal battery pack and reduce the possibility of battery pack fire.

[0053] The temperature monitoring process in S8 is as follows: set a warning peak , generally not exceeding 40 degrees. When the temperature sensing module senses that the internal temperature of a box exceeds this peak value, the refrigeration box 81 immediately extracts gas from the box and creates cold air to be sent to each box. In this way, if the internal temperature of the box is maintained at a higher value due to external environmental reasons, the refrigeration module can cool it down in time to avoid the battery pack that has been tested abnormally from catching fire or exploding under high temperature stimulation; if the abnormal battery gradually generates hidden dangers during transportation and begins to heat up, the refrigeration module can also perform emergency cooling in the first time.
