Description

Technical Field

[0001] The utility model belongs to the technical field of battery replacement equipment, and specifically relates to a thermal runaway battery removal device. Background Art

[0002] With the development of new energy technologies, more and more vehicles are powered by batteries. Electric vehicles can be recharged through charging or battery swapping. To save charging time, electric vehicles such as logistics vehicles, light trucks, and other new energy commercial vehicles, as well as heavy trucks, often use battery swapping. Drivers drive their vehicles to the nearest battery swapping station for battery swapping.

[0003] A battery swap station includes equipment such as a charging compartment for storing and charging batteries, a battery transfer device, and a battery swap device. Improper storage of battery packs in the battery compartment or during charging will inevitably lead to thermal runaway of the battery pack. If batteries in thermal runaway are not promptly handled, fires or even explosions may occur. When thermal runaway occurs, the battery pack is transferred and placed in a fire extinguisher. Patent documents such as CN 109969034B and CN213565502 U disclose relevant technical solutions.

[0004] The above technical solution has the following technical problems: the battery transfer process requires the implementation of motor control-related actuators. If the control fails, the thermal runaway battery cannot be transferred out, which will have a major impact on the entire battery storage warehouse and may cause a major accident. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device for removing a battery with thermal runaway, which is arranged in a battery explosion-proof compartment. By arranging the center of gravity of a battery flip frame on one side of a hinged joint so that the battery automatically rotates toward a battery discharge port in a free state, and then by designing a flip frame limit assembly that is driven to release the limit when the battery moves in the compartment, the flip frame is controlled to flip. A mechanical structure is used to realize the transfer of the battery with thermal runaway, which has good stability and strong reliability, and can ensure that the battery with thermal runaway is removed from the compartment.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a thermal runaway battery removal device is arranged in a battery explosion-proof compartment, including a battery flip frame whose bottom is hinged to the battery explosion-proof compartment and rotates toward the battery discharge port of the battery explosion-proof compartment under the action of gravity when in a free state. The key lies in: a flip frame limit assembly is provided in the battery explosion-proof compartment, which is driven by the battery to release the limit of the battery flip frame and put the battery flip frame in a free state.

[0007] Furthermore, a hinged seat connected to the battery flip frame is provided in the battery explosion-proof compartment, and the center of gravity of the battery flip frame is located between the hinged seat and the battery discharge port.

[0008] Furthermore, the flip frame limit assembly includes one or more limit plates arranged along the length direction of the battery flip frame, a limit rod, a limit sleeve fixed on the inner side wall of the battery explosion-proof compartment and limiting the limit rod, and a contact plate connected to the limit rod and in contact with the battery. The two ends of the limit rod are respectively connected to two adjacent limit plates or respectively connected to the limit plate and the contact plate.

[0009] Furthermore, at least two groups of the limiting rods and limiting sleeves are provided along the height direction of the limiting plate.

[0010] Furthermore, an avoidance groove cooperating with the limiting plate is provided on the battery flip frame.

[0011] Furthermore, a buffer block is provided at the bottom of the battery explosion-proof compartment and matches the battery flip frame.

[0012] Furthermore, the battery explosion-proof compartment is located at the top of the inner side wall of the battery storage compartment, and an opening matching the battery discharge port is provided on the battery storage compartment.

[0014] Furthermore, a guide bar is provided on the slide for guiding the battery.

[0015] Furthermore, a smoothing strip fixed to the battery flip frame is provided below the slide, and the smoothing strip is limited in the grooved plate at the bottom of the slide.

[0016] The beneficial effects of the present invention are as follows: by designing the hinged position of the battery flip frame and providing a flip frame limit assembly that is driven by the battery to release the limit on the battery flip frame, the battery flip frame automatically rotates toward the battery discharge port using gravity. Compared with the existing motor-driven method, the entire device has good stability and high reliability, ensuring that batteries with thermal runaway can be moved out of the warehouse.

[0022] See attached Figure 1-3 The present invention provides a device for removing a battery in a thermal runaway state, which is disposed within a battery explosion-proof compartment 2. The device comprises a battery flip rack 3 whose bottom is hingedly connected to the battery explosion-proof compartment 2 and which, when in a free state, rotates toward a battery discharge port 2-1 of the battery explosion-proof compartment 2 under the action of gravity; and a flip rack limiting assembly disposed within the battery explosion-proof compartment 2 and driven by the battery to release the battery flip rack 3 from its position and free it.

[0023] In this embodiment, the battery explosion-proof compartment 2 is arranged in the battery storage compartment 1 for storing batteries and is located at the top of the inner side of its side wall. Its battery entrance is consistent with the battery entrance of the battery storage compartment 1 and is located on one side of the battery storage compartment 1. An opening is provided on the battery storage compartment 1 to match the battery discharge outlet 2-1 of the battery explosion-proof compartment 2.

[0024] The battery explosion-proof compartment 2 is formed by enclosing a partition 2-2, which serves to isolate the batteries in the battery compartment of the battery storage rack 1-1 in the battery storage compartment 1, and the opening direction of the battery inlet and outlet is consistent with the opening direction of the battery compartment in the battery storage compartment 1.

[0025] When the battery has thermal runaway or other phenomena and needs to be discharged to the fire extinguisher box 13 immediately, the transfer device in the battery swap station (such as a stacker, a battery push-pull device or a battery swap device) moves it out of the battery compartment of the battery storage rack 1-1 in the battery storage compartment 1 and transfers it to the battery explosion-proof compartment 2. After the battery moves a certain distance into the battery explosion-proof compartment 2, it will drive the contact plate 8 in the flip rack limit assembly to move together to release the limit on the battery flip rack 3. Under the action of gravity, the battery flip rack 3 rotates toward the battery discharge outlet 2-1, and the battery slides along the top surface of the battery flip rack 3 under the action of gravity and falls into the fire extinguisher box 13 outside the battery discharge outlet 2-1.

[0026] Specifically, a hinged seat 4 connected to the battery flip frame 3 is provided in the battery explosion-proof compartment 2. The center of gravity of the battery flip frame 3 is located between the hinged seat 4 and the battery outlet 2-1 so that the battery flip frame 3 always rotates toward the battery outlet 2-1 after the limit is released.

[0027] See attached Figure 1The flip frame limit assembly includes one or more limit plates 5 arranged along the length direction of the battery flip frame 3, a limit rod 6, a limit sleeve 7 fixed to the side wall of the battery explosion-proof compartment 2 and limiting the limit rod 6, and a contact plate 8 connected to the limit rod 6 and in contact with the battery. At least two sets of limit rods 6 and limit sleeves 7 are arranged along the height direction of the limit plate 5. The two ends of the limit rod 6 are respectively connected to two adjacent limit plates 5 or respectively connected to the limit plate 5 and the contact plate 8. In this embodiment, there are multiple limit plates 5, so there are also multiple limit rods 6. Two sets of limit rods 6 and limit sleeves 7 are arranged along the height direction of the limit plate 5, and the contact plate 8 is connected to both limit rods 6. The battery flip frame 3 is provided with an avoidance groove 3-1 that cooperates with the limit plate 5. When the battery contacts the contact plate 8 and the limiting plate 5 is driven to move by the limiting rod 6 , the limiting plate 5 enters the avoidance groove 3 - 1 or is located outside the battery turning frame 3 , thereby releasing the limitation on the battery turning frame 3 .

[0028] A buffer block 9 is provided at the bottom of the battery explosion-proof compartment 2 to cooperate with the battery flip frame 3 , which plays a role of buffering and limiting when one side of the flip frame rotates to the bottom of the compartment.

[0029] See attached Figure 2 and 3 In order to facilitate the batteries to slide off the battery flip rack 3, a slide 10 for carrying the batteries from the transfer device is provided on the top surface of the battery flip rack 3. In order to facilitate the batteries to enter the battery explosion-proof compartment, a guide bar 11 is provided on the slide 10 to guide the batteries, and a roller that cooperates with the guide bar 11 is provided at the bottom of the battery. A smooth bar 12 fixed to the battery flip rack 3 is provided below the slide 10, so that the batteries can quickly slide off the top surface of the battery flip rack 3 together with the slide 10. The smooth bar 12 is limited in the groove plate 10-1 at the bottom of the slide 10. By designing the smooth bar 12, the resistance of the slide 10 and the battery during the movement toward the battery discharge port 2-1 can be reduced. There are multiple groups of smooth bars 12 and groove plates 10-1 along the length direction of the battery flip rack 3. The two sides of the smooth strip 12 are located in the grooved plate 10-1 to limit the slide 10, and the pulleys thereon support the slide 10 to ensure that the battery does not cause the slide 10 to move along when it moves onto the slide 10 and does not restrict the movement of the slide 10 toward the battery outlet 2-1 after the battery flip rack 3 is flipped.

[0030] During the specific use of the battery explosion-proof warehouse of the present invention, when it is found that the battery has thermal runaway or other phenomena and needs to be immediately transferred to the fire box 13, the transfer device moves it out of the battery compartment of the battery storage compartment 1 and transfers it to the battery explosion-proof compartment 2. After the battery moves a certain distance into the explosion-proof compartment 2 through the battery entrance, it will contact the contact plate 8 and drive it to move together, thereby moving the limit plate 5 and releasing the limit on the battery flip rack 3. Under the action of gravity, the battery flip rack 3 rotates toward the battery discharge port 2-1. During this process, the battery and the slide 10 move downward along the smooth strip 12 and slide out of the battery discharge port 2-1 and fall into the fire box 13.

[0031] After the battery is removed, the battery turning rack 3 is manually rotated and the position limit is re-applied thereto.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for protection of the utility model.
