Description

Technical Field

[0001] This utility model relates to the field of battery swapping cabinet technology, specifically a battery swapping cabinet with fire extinguishing function. Background Technology

[0002] As a new and convenient way to swap batteries, smart battery swapping cabinets are rapidly developing in various industries. They are welcomed by consumers for their intelligence, portability and efficiency. In the past few years, battery swapping cabinets have made great progress and have received widespread attention from consumers. Nowadays, smart battery swapping cabinets are widely used in shared bicycles, electric vehicles, mobile power banks and other fields, which bring users a more intelligent, portable and economical battery swapping experience.

[0003] Application No. 202121555997.9 discloses a vertical automatic fire-extinguishing battery swapping cabinet, including a cabinet body, an electrical control module located inside the cabinet body, several rows of charging compartments located in the upper part of the cabinet body, and a water tank located below the charging compartments. Each charging compartment has a charging cavity for placing and charging batteries. Each charging compartment has a battery safety outlet on its back, and each battery safety outlet has a baffle. The baffle is used to block the battery in the charging cavity, and the opening and closing of the battery safety outlet is controlled by the electrical control module. The bottom of each charging cavity is set at a certain tilt angle. Although this facilitates the battery falling into the water tank from the battery safety outlet when the battery in the charging compartment catches fire, the signal feedback will also be interrupted when the battery fire causes the cabinet to lose power, which will lead to untimely fire extinguishing of the battery. Therefore, a battery swapping cabinet with fire extinguishing function is needed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 5 The present invention provides a technical solution: a battery swapping cabinet with fire extinguishing function, comprising a cabinet body 1, a back plate 2 fixedly connected to the back of the cabinet body 1, a compartment opening 3 proportionally opened on the outer surface of the back plate 2, compartments 4 arranged proportionally inside the cabinet body 1 for placing batteries 7 into the compartments 4, a rear door 5 movably connected to the outer surface of the back plate 2 on one side of the compartment opening 3 via a hinge, batteries 7 connected to the inside of the compartments 4 via cables 6, a lock bracket 9 fixedly connected to the top of the compartments 4 via a lock 8, a fire-fighting glass hole 10 opened on the top of the compartments 4, a water tank 11 provided on one side of the bottom of the cabinet body 1, a support leg 12 movably connected to the bottom of the cabinet body 1, and a rainproof canopy 13 provided on the top of the cabinet body 1.

[0025] Specifically, in combination Figure 2 As shown, a latch 14 is welded to one side of the interior of the rear door 5. The latch 14 is engaged inside the lock 8. A positioning hole 15 is provided on one side of the lock 8 for locking the rear door 5.

[0026] Specifically, in combination Figure 3 As shown, in order to prevent the battery 7 from getting stuck in the compartment 4 when it slips out, a retaining ball 16 is fitted on the outer surface of the cable 6. One side of the cable 6 is connected to the battery 7 through a quick connector 17, and the retaining ball 16 overlaps one side of the compartment 4.

[0027] Specifically, in combination Figure 4 As shown, the lock 8 has an unlocking rod 18 inside, and the lock bracket 9 has a movable plate 19 inside. The movable plate 19 and the lock bracket 9 are elastically connected by a spring 20. A fire glass ball 21 is engaged between the movable plate 19 and the lock bracket 9. The fire glass ball 21 can explode when heated, similar to the principle of a fire sprinkler head.

[0028] Specifically, in combination Figure 1As shown, a reinforcing rib 22 is fixedly welded to the outer surface of the water tank 11 to increase the overall stability of the water tank 11. In addition, in order to further understand the water level of the water tank 11, a water level gauge 24 is fixedly connected to one side of the top of the water tank 11 by a fixed sheet metal 23. A water level line 25 is connected to the top of the water level gauge 24, so as to facilitate timely replenishment of water to immerse and extinguish the fire of the burning battery 7.

[0029] Specifically, in combination Figure 1 As shown, there are two support legs 12, which are respectively set on both sides of the bottom of the cabinet 1. The top of the support legs 12 is provided with ventilation holes 26 on both sides of the cabinet 1, and the sides of the support legs 12 are provided with casters 27 around the bottom of the cabinet 1.

[0030] Specifically, in combination Figure 1 As shown, two support plates 28 are fixedly connected to both sides of the bottom of the rain shelter 13. The two support plates 28 are fixedly connected to the top of the cabinet 1 by screws.

[0031] Specifically, in combination Figure 1 As shown, a crossbeam 29 is fixedly connected to the top of the back panel 2, and a rear maintenance door 30 is movably connected above the crossbeam 29 to facilitate future maintenance of the cabinet 1. The rear maintenance door 30 has two mounting holes 31 on both sides of its bottom for mounting the rear maintenance door 30.

[0032] Working principle: During use, the battery swapping cabinet is designed with the compartment 4 at an angle, allowing the battery 7 inside to slide out. Through the coordinated design of the lock bracket 9, fire-resistant glass bulb 21, movable plate 19, and rear door 5, if the battery 7 inside the compartment 4 catches fire, the flame temperature can penetrate through the fire-resistant glass hole 10, causing the fire-resistant glass bulb 21 between the movable plate 19 and the lock bracket 9 to shatter. This triggers the spring 20 to tighten the movable plate 19, causing it to flip and touch the unlocking rod 18, thus opening the lock 8 and the rear door 5. The battery 7 then slides out of the compartment 4 along its angle, automatically opening the rear door 5 and allowing the battery 7 to slide out of the compartment 4 in case of fire. This achieves the purpose of automatically sliding the burning battery 7 out of the compartment 4.

[0033] When in use, the water tank 11 enables the fire-extinguishing battery swapping cabinet to achieve the effect of water immersion fire extinguishing. Through the coordinated arrangement of the water tank 11 and the cabinet body 1, the burning battery 7 can slide out of the compartment 4 during use. During the fall, the battery 7 will pull out the quick connector 17 on the cable 6 due to gravity, and the battery 7 will then fall into the water tank 11. This achieves the purpose of effectively extinguishing the fire of the battery 7 and preventing the possibility of the battery 7 catching fire and exploding inside the cabinet body 1.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
