Description

Technical Field

[0001] This invention relates to the field of battery box technology, specifically to a battery box with quick battery swapping capability. Background Technology

[0002] A battery box is a group of batteries consisting of several individual batteries, a box body, a battery management system, and related installation structures (equipment). The battery box body, as a component that provides housing and protection for several batteries, is mainly composed of a bottom frame, a side frame, and a top frame.

[0003] Traditionally, a matrix battery pack consisting of several evenly distributed batteries is placed behind a box formed by a bottom frame, side frame, and top frame. Due to the small gaps inside the box, it is difficult to quickly replace and reinstall the evenly distributed individual batteries. Furthermore, as the battery box is used for a long time, if individual individual batteries develop problems such as swelling due to accidents and require maintenance, the aforementioned single battery box structure will also hinder the rapid replacement of faulty individual batteries.

[0034] 2. This invention establishes a vacuum cavity of a certain height between the base and the heat sink plate supporting the individual batteries. Considering that several batteries are evenly distributed and prone to static electricity during use, the vacuum cavity can provide a constant temperature chamber for the matrix battery pack while simultaneously setting up static electricity elimination circuits at the bottom of the battery pack. This effectively reduces the problem of static electricity generation in the battery pack during actual use, thereby improving the cooling speed of the individual batteries.

[0035] 3. This invention sets up multiple sets of lifting power supply mechanisms at equal intervals within multiple bases, and sets up bidirectional transmission components evenly distributed in the gaps between the multiple lifting power supply mechanisms. When a single battery in the matrix battery pack has problems such as expansion or failure and needs to be replaced, the bidirectional transmission components are adjusted to control one or more sets of lifting power supply mechanisms, thereby ensuring that the removed single battery will not damage the surrounding intact batteries, and at the same time avoiding external damage to the battery caused by external clamping.

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0055] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0056] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a battery housing capable of rapid battery swapping.

[0057] Example 1:

[0058] Combination Figures 1-12As shown, the present invention provides a battery box with quick battery swapping capability, comprising multiple evenly distributed individual batteries 500, a protective component 400 disposed outside the multiple individual batteries 500, a quick-installation maintenance mechanism 200 disposed on the protective component 400, a support component 100 disposed on the quick-installation maintenance mechanism 200, and multiple sets of stabilizing sliding components 300 disposed outside the protective component 400. The support component 100 is used to provide bottom protection for the multiple evenly distributed individual batteries 500, the quick-installation maintenance mechanism 200 is used to provide temperature control protection and eliminate static electricity for the multiple individual batteries 500, the multiple sets of stabilizing sliding components 300 are used to provide stable lifting protection for the multiple sets of storage components 270, and the protective component 400 is used to provide storage protection for the multiple evenly distributed individual batteries 500.

[0059] The support assembly 100 includes a base plate 110 disposed at the bottom of a first base 210, a second base 220 and a plurality of third bases 230. A rectangular groove is provided on the top of the base plate 110, and a plurality of clamping plates 120 are disposed in the rectangular groove.

[0060] A linkage shaft 130 is movably installed in the two adjacent clamping plates 120, and both ends of the linkage shaft 130 are provided with insertion holes.

[0061] Through holes are provided at the middle of both ends of the base plate 110;

[0062] The quick-installation maintenance mechanism 200 includes a first base 210 and a second base 220, and a plurality of third bases 230 disposed between the first base 210 and the second base 220. Each of the first base 210, the second base 220 and the plurality of third bases 230 is provided with a storage component 270 for holding a single battery cell 500. Two sets of lifting components 260 are provided on the storage component 270. A lifting power supply mechanism 240 and a bidirectional transmission component 250 for bidirectionally supplying power to the lifting power supply mechanism 240 are provided directly below the storage component 270.

[0063] The stabilizing sliding assembly 300 includes a first cover 310 and a second cover 320, both of which are made of aluminum alloy.

[0064] A lead screw 330 is movably installed inside the first cover 310, and a driven gear 340 is installed on the lead screw 330;

[0065] The second cover 320 has a positioning rod 350 movably installed inside;

[0066] A main spring 360 is provided on the outside of the lead screw 330, a secondary spring 370 is provided on the outside of the positioning rod 350, and a screw sleeve 273 is movably installed on the threaded section of the lead screw 330.

[0067] The protective assembly 400 includes a battery casing 410 mounted on top of a first base 210, a second base 220, and a plurality of third bases 230;

[0068] A left wing cover 420 is provided at one end of the battery casing 410, and a right wing cover 430 is provided at the other end of the battery casing 410.

[0069] Both the left wing cover 420 and the right wing cover 430 have pre-installed holes at their bottom ends. A motor 440 is installed in the pre-installed hole inside the left wing cover 420, and a drive shaft 450 is installed on the transmission shaft inside the motor 440.

[0070] Since the battery boxes currently in use are mainly made of welded or pre-stretched sheet metal, they can only provide simple storage and protection for a number of individual batteries. When several batteries are evenly distributed inside the battery box, they will be obstructed when individual batteries need to be reinstalled or replaced. At the same time, the batteries inside these battery boxes need to be removed using external clamps. If the clamping force applied by the external clamps is too large, it will damage the battery body.

[0071] The battery box is equipped with a first base 210, a second base 220 and multiple third bases 230, and multiple sets of storage components 270 are evenly distributed in the first base 210, the second base 220 and the multiple third bases 230. Two sets of lifting components 260 are provided on each set of storage components 270. When multiple individual batteries 500 are placed along the inner cavity of the battery casing 410, the multiple individual batteries 500 can be accommodated and supported by multiple evenly distributed heat dissipation plates 271. At this time, the multiple individual batteries 500 placed can be effectively temperature controlled and static electricity eliminated during actual use.

[0072] If an individual battery cell 500 malfunctions, swells, or leaks during use, starting the motor 440 will cause the rotating drive shaft 450 to drive multiple linkage shafts 130 and multiple first double-headed rollers 254. Based on the position of the individual faulty battery cell 500, one of the sliding trusses 251 will be adjusted. The second double-headed roller 253, after being moved laterally, will drive the auxiliary screw 245 directly below the faulty battery cell 500. After the vertical shaft 241 is linked, the chain 242 will drive the driven gear 340. At this time, the lead screw 330 will help push the heat sink 271 to rise as a whole, and the faulty battery cell 500 placed on the heat sink 271 can be quickly removed without damaging the surrounding intact batteries.

[0097] Example 4:

[0098] Combination Figure 9 As shown, in the above embodiment, the first base 210, the second base 220 and the plurality of third bases 230 are all made of stainless steel sheet, and the bottom of the inner side of the first base 210 and the second base 220 are provided with main transverse grooves, while the bottom of the two sides of the plurality of third bases 230 are provided with symmetrically distributed secondary transverse grooves.

[0099] Preferably, the assembly structure of the first base 210, the second base 220 and the multiple third bases 230 is only for demonstrating their specific structure. The first base 210, the second base 220 and the multiple third bases 230 are pre-pressed into a U-shaped structure by a stretching device and then punched.

[0100] The hollow cavity shell formed by multiple heat dissipation plates 271, multiple sets of columns 274, and the aforementioned first base 210, second base 220, and multiple third bases 230 is used to arrange cables for eliminating static electricity, and its interior can be further filled with moisture-proof medium.

[0101] Preferably, the housing of the device is only one type of unidirectional matrix battery. Depending on the different irregularly shaped battery boxes, the device housing is further arranged in an array inside the irregularly shaped battery box.

[0102] Working principle and usage process of the present invention: At present, the battery box is an important protective component of the battery system and plays an irreplaceable role in protecting the battery. The battery box used in traditional matrix battery packs is mainly welded together from the bottom frame, the side frame and the top frame. However, the battery box with this structure can only provide storage protection for the matrix battery pack. After the batteries are evenly distributed in this type of battery box, the single battery is difficult to put in and take out.

[0103] Therefore, for a matrix battery pack, a battery casing 410 is provided outside the evenly distributed individual batteries 500, and a first base 210 and a second base 220 are provided at the bottom of the battery casing 410, and a plurality of third bases 230 are evenly distributed between the first base 210 and the second base 220. At this time, the first base 210, the second base 220 and the plurality of third bases 230 can form a U-shaped frame. At the same time, multiple sets of storage components 270 are provided inside the first base 210, the second base 220 and the plurality of third bases 230. The lifting of an independent set of storage components 270 is provided by two sets of lifting components 260 to provide a stable support platform. At this time, the multiple sets of storage components 270 provided at the bottom of the battery casing 410 can provide a flat pressure plate for multiple batteries.

[0104] When multiple individual batteries 500 are evenly distributed in the inner cavity of the battery casing 410 and supported by multiple heat dissipation plates 271, each individual battery 500 can be accommodated by its own independent heat dissipation plate 271.

[0105] During battery pack assembly, if an individual battery cell 500 needs to be repositioned or removed due to assembly sequence errors, human error, or other factors, the motor 440 can be activated. The internal transmission of the motor 440 will then drive the drive shaft 450. This will unify the drive mechanism formed by multiple linkage shafts 130 and multiple first double-headed rollers 254. The user then needs to control the sliding truss 251 near the battery cell 500 that needs to be reinstalled or removed. When the sliding truss 251 moves towards the battery cell 500 to be replaced... As 00 approaches, the first double-headed roller 254, which moves laterally along the sliding truss 251, will engage with the auxiliary screw 245 directly below the aforementioned single battery 500. At this time, the rotation of the auxiliary screw 245 will drive the vertical shaft 241, which in turn will drive the chain 242. The other end of the chain 242 will drive the driven gear 340. The vertically rotating lead screw 330 will then push the screw sleeve 273 upward. At this time, a horizontally placed heat sink 271 will push the aforementioned single battery 500 that needs to be reinstalled upward.

[0106] When the battery pack is being maintained and repaired, sampling inspections can be conducted based on the specific condition of each individual battery cell 500. Following the above method, a platform for rapid battery swapping can be provided for the evenly distributed individual battery cells 500, greatly reducing the risk of damage between individual battery cells 500.

[0107] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
