Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a lithium battery protection plate which is convenient for stacking. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Their safety, specific capacity, self-discharge rate and performance-price ratio are superior to lithium ion batteries. Due to its own high technical requirements, only companies in a few countries are producing this type of lithium metal battery.

[0003] After searching, the Chinese patent publication number CN213278168U discloses a lithium battery protection plate that is easy to stack. Spring grooves are provided at four corners of the upper end of the protection plate, and a fixed spring column integrally formed with the bottom of the spring groove is provided in the spring groove, and an elastic spring is sleeved on the fixed spring column. Rubber semi-circular balls connected by glue are provided on both sides of the upper and lower ends of the protection plate, positioning grooves are provided on both sides of the upper end of the protection plate, and a clamping plate connected by a rotating shaft is provided between the one-way splints, and an integrally formed clamping slot block is provided on one side of the lower end of the clamping plate. Through the setting of the overall structure, the lithium batteries are easy to operate when stacked, and the structure is practical and uncomplicated, and the use cost is low, which is conducive to the promotion of this structure; the compression between the rubber semi-circular balls plays a shock-absorbing role on the stacked protection plates, and also increases the friction between the plates, which is conducive to the stable stacking of the lithium battery protection plates.

[0022] The prior art achieves a shock-absorbing effect on the stacked protection plates by squeezing between the rubber semi-circular balls, while also increasing the friction between the plates, which is beneficial for the stable stacking of the lithium battery protection plates.

[0023] The inventor of the utility model found that after stacking the solar panels, it is not convenient to clamp them for fastening. When touched by external force, the stacked solar panels are easy to loosen, which is not convenient for protecting the solar panels when stacking.

The number of the twisting components 5 is two groups, which are symmetrically arranged on the left and right inner surfaces of the protection frame 4, wherein a fixing component 6 is arranged on the front side of the twisting component 5 on the left side, and the fixing component 6 includes a fixing disk 601, which is fixedly connected to the outer surface of the rotating shaft 501, and a circle of small holes is provided on the outer surface of the fixing disk 601, and a fixer 602 is arranged on the left side of the fixing disk 601, and the fixer 602 is fixedly connected to the front side of the protection frame 4, and the fixer 602 is specifically a password lock. The lock on the fixer 602 is inserted into the small hole on the fixing disk 601 to fix the fixing disk 601, so as to achieve the fixing effect of the rotating shaft 501. A connecting component 7 is arranged on the right side of the twisting component 5 located on the right side, and the twisting component 5 includes a rotating shaft 501, and the rotating shaft 501 penetrates and is rotatably connected to the front and back sides of the protective frame 4. A gear 502 is fixedly connected to the outer surface of the rotating shaft 501. The gear 502 is arranged behind the capstan 503 and leaves a gap with the capstan 503. The two gears 502 in the two groups of twisting components 5 are meshed with each other. The rotation of one rotating shaft 501 will drive the gear 502 to rotate the other rotating shaft 501. The outer surface of the rotating shaft 501 is fixedly connected to the capstan 503, and a rope 504 is connected between the capstan 503 and the bottom plate 1. The rope 504 penetrates and moves through the top plate 3. The rope 504 is used to pull the bottom plate 1 toward the top plate 3. A shielding component 8 is arranged on the front and back of the protective frame 4.

[0025] like Figure 1-3 As shown, specifically, when in use, the lithium battery panels are first stacked and then placed between the bottom plate 1 and the top plate 3. At this time, by rotating the rotating shaft 501, the rotating shaft 501 will drive the other rotating shaft 501 to rotate through the engagement of the two gears 502, so that the left and right winches 503 twist the rope 504 to pull the bottom plate 1 toward the top plate 3, so that it clamps the stacked lithium battery panels and plays a fixing role. At this time, the fixing plate 601 is fixed by the fixer 602 to fix the rotating shaft 501. At this time, the other rotating shaft 501 connected to the rotating shaft 501 through the gear 502 will also be fixed to ensure the fixing effect, thereby achieving the clamping and fixing effect of the lithium battery panels.

[0026] like Figure 1-3As shown, the connecting assembly 7 includes a crown gear 701, which is fixedly connected to the outer surface of the rotating shaft 501, a bevel gear 702 is meshed on the right side of the crown gear 701, and a rotating shaft 703 is fixedly connected to the right side of the bevel gear 702. A shaft bracket 704 is movably sleeved on the outer surface of the rotating shaft 703, and the shaft bracket 704 is used to support the rotating shaft 703. The shaft bracket 704 is fixedly connected to the top of the top plate 3.

The rotating shaft 703 is provided with a transmission shaft for transmission by the transmission belt 804, and an opening is provided on the protective frame 4, and the opening is adapted to the transmission belt 804, and the transmission belt 804 passes through the opening.

[0027] like Figure 1-3 As shown, specifically, when the rotating shaft 501 rotates to pull the bottom plate 1 toward the top plate 3, the crown gear 701 will be driven to rotate, and the bevel gear 702 will drive the bevel gear 702 to rotate the rotating shaft 703. The rotation of the rotating shaft 703 will drive the transmission belt 804 to rotate the transmission wheel 803. Since the transmission wheel 803 is coaxially arranged with the hinge point of the baffle 801 and the protective frame 4, the rotation of the transmission wheel 803 will cause the baffle 801 to flip on the protective frame 4, and the baffle 801 will flip downward to cover the lithium battery panels stacked between the bottom plate 1 and the top plate 3, thereby achieving a protective effect.
