Description

Technical Field

[0001] This utility model relates to the field of battery swapping equipment technology, specifically to an emergency treatment device for thermal runaway batteries. Background Technology

[0002] With the development of new energy technologies, more and more cars are using batteries as their power source. Electric vehicles can be recharged in two ways: charging and battery swapping. Battery-swapping new energy passenger vehicles generally use a chassis-based battery swapping system. This involves unlocking and removing the depleted battery from the bottom of the car using swapping equipment at a battery swapping station, and then installing a fully charged battery in the bottom of the car.

[0003] To meet the high demand for battery replacements, battery swapping stations typically store a large number of batteries. Improper storage or unavoidable thermal runaway risks during charging can easily lead to fires or even explosions.

[0004] In existing technologies, an emergency compartment is often integrated within the battery rack. This emergency compartment contains a fire water tank, a battery tray for holding the thermal runaway battery, and an electronically controlled mechanism for limiting and releasing the battery tray so that the tray and battery fall together into the fire water tank. For example, CN115489489A discloses a related technical solution. However, in the above technical solution, the electronically controlled approach has poor reliability, and the thermal runaway battery may affect the mechanism, rendering it uncontrollable and ultimately making it impossible to handle the thermal runaway battery. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an emergency treatment device for thermal runaway batteries. When receiving the battery, the battery tray is limited by a limiting component. After the thermal runaway battery is placed on the battery tray by the battery transfer equipment, the limiting component of the battery transfer equipment is used to release the limiting of the battery tray. The mechanical limiting structure has good reliability and can realize the rapid treatment of thermal runaway batteries.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an emergency treatment device for thermal runaway batteries, including a water tank, a battery tray, and a vertical guide assembly disposed between the water tank and the battery tray. The key feature is that a limiting assembly is provided between the water tank and the battery tray. The limiting assembly includes two rollers symmetrically disposed on the battery tray and two sliders symmetrically disposed on the water tank. The sliders are slidably limited on the water tank and are provided with horizontal limiting grooves for limiting the rollers.

[0007] Furthermore, a mounting bracket is provided on the battery tray, and the roller is connected to the mounting bracket.

[0008] Furthermore, a support plate for supporting the battery is provided on the mounting bracket.

[0009] Furthermore, the mounting bracket is provided with a positioning groove for positioning the battery.

[0010] Furthermore, the vertical guide assembly includes a guide block disposed on the battery tray and a guide groove disposed on the water tank and cooperating with the guide block.

[0011] Furthermore, a drive plate is provided between the two sliders to drive all sliders to move horizontally under the action of external force and release the horizontal limiting groove from limiting the roller.

[0012] Furthermore, at least two sets of limiting components are provided along the length of the water tank, and a connecting rod is provided between adjacent sliders on the same side of the water tank. A drive plate is provided between two sliders in a limiting component near the end of the water tank, which drives all sliders to move horizontally under the action of external force and releases the horizontal limiting groove from limiting the roller.

[0013] Furthermore, both ends of the drive plate are connected to the corresponding sliders via a linkage assembly. The linkage assembly includes a first link connected to one end of the drive plate and hinged in the middle to the water tank, and a second link hinged at both ends to the first link and the slider, respectively.

[0014] Furthermore, a slider connecting assembly is provided on the water tank. The slider connecting assembly includes a C-shaped limiting plate fixed to the water tank and a first end plate and a second end plate respectively fixed to both ends of the limiting plate. The slider is provided with a sliding groove that mates with the boss in the limiting plate.

[0015] One end of the slider is provided with a first sliding rod that passes through the first end plate and is hinged to the connecting rod or the second connecting rod; the other end is provided with a second sliding rod that passes through the second end plate and is hinged to the connecting rod.

[0016] Alternatively, a first sliding rod can be provided at one end of the slider, passing through the first end plate and hinged to the connecting rod.

[0017] Furthermore, a spring is provided between the slider and the first end plate, and the spring is fitted onto the first slide rod.

[0018] The beneficial effects of this utility model are: 1. The horizontal limit between the battery tray and the water tank is achieved by the limiting component. When a thermal runaway battery is detected, the battery transfer device places the battery on the battery tray and releases the limit by driving the slider in the limiting component to move horizontally. Both the limiting and the release of the limit are achieved through a mechanical structure, which has high reliability; 2. The two ends of the drive plate drive the sliders located on both sides of the water tank to move synchronously through corresponding connecting rod components, which has good synchronization.

Detailed Implementation

[0026] See appendix Figure 1-6 This utility model provides an emergency treatment device for thermal runaway batteries, including a water tank 1, a battery tray 2, a vertical guide assembly disposed between the water tank 1 and the battery tray 2, and a limiting assembly disposed between the water tank 1 and the battery tray 2.

[0027] See appendix Figure 1-4 The aforementioned limiting components include two rollers 3 symmetrically arranged on the battery tray 2 and two sliders 4 symmetrically arranged on the water tank 1. The sliders 4 are slidably limited on the water tank 1 and are provided with horizontal limiting grooves 4-1 for limiting the rollers 3. After the thermal runaway battery is supported on the battery tray 2, under the action of external force, all sliders 4 are synchronously driven to move horizontally, causing the horizontal limiting grooves 4-1 to leave the corresponding rollers 3, thereby releasing the horizontal limitation on the battery tray 2. Under the action of gravity, the battery tray 2 and the thermal runaway battery on it move downward synchronously into the water tank 1 for cooling and fire extinguishing.

[0028] See appendix Figure 4 and 6The battery tray 2 is equipped with a mounting bracket 5 that matches each roller 3, and the roller 3 is connected to the mounting bracket 5. The mounting bracket 5 is equipped with a tray 5-1 for supporting the battery and a positioning groove 5-2 for positioning the battery in cooperation with the positioning block on the battery. This design facilitates the telescopic component in the battery transfer equipment to move the battery to place and position it on the mounting bracket 5 and reset it through the space between the tray 5-1 and the battery tray 2.

[0029] See appendix Figure 3 and 4 The aforementioned vertical guide components are arranged in four sets around the battery tray 2. Each set of vertical guide components includes a guide block 6 set on the battery tray 2 and a guide groove 1-1 set on the water tank 1 and cooperating with the guide block 6.

[0030] Example 1: See Appendix Figure 1-6 In this embodiment, to ensure stable support and positioning of the battery, at least two sets of the aforementioned positioning components are provided along the length of the water tank 1. Connecting rods 7 are provided between adjacent sliders 4 on the same side of the water tank 1. Between two sliders 4 in a set of positioning components near the end of the water tank 1, a drive plate 8 is provided. This drive plate, under the driving force of linear drive components such as cylinders or hydraulic cylinders, or the outward extension force of the telescopic components in battery transfer equipment (such as battery swapping equipment with lifting drive components and telescopic components, palletizers, stackers, etc.), drives all sliders 4 to move horizontally and releases the horizontal positioning groove 4-1 from the roller 3.

[0031] Both ends of the drive plate 8 are connected to the corresponding sliders 4 via connecting rod assemblies. The connecting rod assembly includes a first connecting rod 9 connected to one end of the drive plate 8 and hinged in the middle to the water tank 1, and a second connecting rod 10 whose two ends are respectively hinged to the first connecting rod 9 and the slider 4. By designing the connecting rod assembly, the slider 4 can be moved in the opposite direction of the force, thereby releasing the restriction on the roller 3.

[0032] A slider connecting assembly is provided on the water tank 1 to realize the sliding limit of the slider 4 on the water tank 1. The slider connecting assembly includes a limit plate 11 fixed on the water tank 1 and in the shape of a C, and a first end plate 12 and a second end plate 13 respectively fixed at both ends of the limit plate 11. The slider 4 is provided with a sliding groove 4-2 that cooperates with the boss in the limit plate 11. One end of the slider 4 is provided with a first slide rod 14 that passes through the first end plate 12 and is hinged to the connecting rod 7 or the second connecting rod 10, and the other end is provided with a second slide rod 15 that passes through the second end plate 13 and is hinged to the connecting rod 7. Alternatively, one end of the slider 4 is provided with a first slide rod 14 that passes through the first end plate 12 and is hinged to the connecting rod 7. The slider 4 in the set of limiting components near the drive plate 8 needs to be connected to the second connecting rod 10 and the connecting rod 7 at both ends, so a first sliding rod 14 and a second sliding rod 15 are provided; the slider 4 in the limiting component in the middle position needs to be connected to the connecting rod 7 of the adjacent slider 4 at both ends, so a first sliding rod 14 and a second sliding rod 15 are also provided; while the slider 4 in the limiting component at the farthest end only needs to be connected to the adjacent slider 4, so only a first sliding rod 14 is provided. In this embodiment, two sets of limiting components are provided along the length of the water tank 1.

[0033] A spring 16 is provided between the slider 4 and the first end plate 12 so that the drive plate 8 and the slider 4 can be reset under the action of the spring force after the external force is released. The aforementioned spring 16 is fitted on the first slide rod 14, and its two ends are limited by the first end plate 12 and the slider 4 respectively.

[0034] Taking the release of the limit via a battery transfer device as an example, the thermal runaway battery handling process in this embodiment is as follows: See Appendix Figure 6 The telescopic assembly in the battery transfer device moves the thermal runaway battery above the mounting bracket 5. Then, by controlling the telescopic assembly to extend and retract, the battery is positioned and supported on the mounting bracket 5. The telescopic assembly then retracts to its initial position through the space between the support plate 5-1 and the battery tray 2 in the mounting bracket 5. The battery transfer device controls the telescopic assembly to move downward to one side of the drive plate 8. Then, it controls the telescopic assembly to extend outward, causing the drive plate 8 to move. This, through the linkage assembly and connecting rod 7, causes all the sliders 4 to move towards one side of the battery transfer device. This causes the horizontal limiting groove 4-1 on the slider 4 to no longer limit the roller 3. Under the action of gravity, the battery tray 2 and the battery on it fall into the water tank 1 for cooling and / or fire extinguishing.

[0035] Example 2: Unlike Example 1, no spring 16 is provided between slider 4 and the first end plate 12, and slider 4 is manually reset.

[0036] Example 3: Unlike Example 1, no linkage assembly is provided. The two ends of the drive plate 8 are directly connected to the two nearest sliders 4. The limitation is released by extending the telescopic assembly outwards to move the drive plate 8. In this example, the movement direction of the sliders 4 is the same as the movement direction of the drive plate 8.

[0037] Example 4: Unlike Example 3, this example only has one set of limiting components. Between the two sliders 4 in the limiting components, there is a drive plate 8 that is driven by the telescopic component in the battery transfer device to move all sliders 4 horizontally and release the horizontal limiting groove 4-1 from limiting the roller 3.
