Technical Field

[0001] The present invention relates to the technical field of accommodating devices, and particularly to an accommodating device suitable for a lithium battery of a new energy vehicle and having a heat dissipation function. Background Art

[0002] In modern electronic devices, electric vehicles, and renewable energy storage systems, lithium batteries are widely used due to their high energy density, long lifespan, and relatively light weight. However, lithium batteries generate heat during charging and discharging, especially under high load conditions. If the battery temperature is too high, it may lead to a decrease in battery efficiency and even pose safety problems. Therefore, a lithium battery accommodating device with a heat dissipation function becomes particularly important.

[0003] The patent with the patent announcement number CN211929547U relates to the technical field of accommodating devices, including a box body and a base. The box body is fixedly connected to the base through spring rods. Transverse spring rods are relatively connected to the sides of the spring rods. Springs are provided between the transverse spring rods and the box body and the base respectively. A damping cylinder is provided outside the transverse spring rods and the springs. Mounting plates and damping pads are fixedly arranged at intervals outside the damping cylinder. A placement groove is provided at the bottom inside the box body, and a lithium battery is placed in the placement groove. Pressure plates are relatively arranged on both sides of the placement groove at the bottom inside the box body. The top of the pressure plate is provided with an inclined surface. A baffle is fixedly arranged at the bottom inside the box body. The pressure plate is connected to the baffle through a spring. Inclined ventilation openings are relatively arranged on the sides of the box body. A first sealing pad is fixedly arranged on the inner wall of the inclined ventilation opening. A rotating plate matching the inclined ventilation opening is arranged inside the inclined ventilation opening. The technical solution provided by this patent can overcome the defects of the prior art, such as not having a heat dissipation function and relatively poor overall structural stability of the device.

[0004] In the above patent, by overcoming the defects of the prior art, such as not having a heat dissipation function and relatively poor overall structural stability of the device, however, when the device is impacted, the internal lithium battery may shake and collide, resulting in damage to the lithium battery and reducing its service life. Therefore, an accommodating device suitable for a lithium battery of a new energy vehicle and having a heat dissipation function is designed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an accommodating device suitable for a lithium battery of a new energy vehicle and having a heat dissipation function, and solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A containment device for a lithium battery of a new energy vehicle with heat dissipation function, including a containment box, a heat dissipation mechanism is provided on the surface of the containment box, an air outlet is provided on the surface of the containment box, and a shock absorption device, a support device and a fire prevention device are also included. The shock absorption device includes a containment plate, a connecting block one, a rotating rod one, a connecting block two, a sleeve, a fixed shaft, a limiting groove one and a limiting block one. The containment plate is slidably installed on the inner wall of the containment box. The connecting block one is fixedly installed below the containment plate. The rotating rod one is rotatably installed in the inner wall of the connecting block one. The connecting block two is rotatably installed at the end of the rotating rod one away from the connecting block one. The sleeve is fixedly installed below the connecting block two. The fixed shaft is fixedly installed on the inner wall of the containment box. The limiting groove one is opened on the surface of the fixed shaft. The limiting block one is slidably installed in the inner wall of the limiting groove one. When the device for placing the lithium battery is impacted, the containment plate moves downward under the action of the lithium battery. The movement of the containment plate drives the connecting block one to move downward. The movement of the connecting block one drives the rotating rod one to move. The movement of the rotating rod one drives the connecting block two to move. The movement of the connecting block two drives the sleeve to move. The movement of the sleeve stretches the spring one, and the stretching of the spring one reduces the impact force.

[0007] According to the above technical solution, the sleeve is slidably connected to the circumferential surface of the fixed shaft. A spring two is provided between the limiting block one and the fixed shaft. When the sleeve moves and contacts the limiting block one, the limiting block one moves into the limiting groove one under the action of the sleeve. The movement of the limiting block one compresses the spring two to contract. The restoration of the spring two drives the limiting block one to reset. The reset of the limiting block one engages and limits the sleeve.

[0008] According to the above technical solution, there are two sleeves. The two sleeves are symmetrically distributed with the fixed shaft as the axis. A spring one is provided between the two sleeves. After the limiting of the limiting block one is released, the spring one restores. The restoration of the spring one drives the sleeve to reset. The reset of the sleeve drives the connecting block two to move. The movement of the connecting block two drives the rotating rod one to move. The movement of the rotating rod one drives the connecting block one to move upward. The movement of the connecting block one drives the containment plate to move upward.

[0009] According to the above technical solution, the support device includes a slider, a connecting block three, a rotating rod two, a support rod, a support plate, a limiting groove two and a limiting block two.

The rotating rod two is rotatably installed in the inner wall of the connecting block three. The support rod is slidably installed in the inner wall of the containment box. The support plate is fixedly installed on the inner wall of the containment box. The limiting groove two is opened on the surface of the support plate. The limiting block two is slidably installed in the inner wall of the limiting groove two. When the device for placing the lithium battery is impacted, the sleeve moves and contacts the slider. The slider moves in the direction close to the support rod under the action of the sleeve. The movement of the slider drives the connecting block three to move. The movement of the connecting block three drives the rotating rod two to move. The movement of the rotating rod two drives the support rod to move upward. The upward movement of the support rod supports the containment box.

[0010] According to the above technical solution, one end of the support rod and the second rotating rod away from the third connecting block are rotatably connected. The support rod is slidably connected to the surface of the receiving plate. The support rod moves to contact the second limiting block. Under the action of the support rod, the second limiting block moves into the second limiting groove. The second limiting block resets to limit the support rod.

[0011] According to the above technical solution, the side of the second limiting block close to the support rod is set as an inclined plane. A third spring is arranged between the second limiting block and the support plate. When the second limiting block moves, it compresses the third spring to contract. When the third spring restores, it drives the second limiting block to reset.

[0012] According to the above technical solution, the flame-proof device includes a first tooth block, a gear, a gas valve, a gas storage tank, a baffle plate and a second tooth block. The first tooth block is fixedly installed on the surface of the support rod. The gear is rotatably installed on the inner wall of the receiving box. The gas valve is rotatably installed on the inner wall of the receiving box. The gas storage tank is fixedly installed on the surface of the receiving box. The baffle plate is slidably installed on the inner wall of the receiving box. The second tooth block is fixedly installed on the side of the baffle plate close to the gear. When the support rod moves upward, it drives the first tooth block to move. The first tooth block moves to engage the gear. Under the action of the first tooth block, the gear rotates. The gear rotates to engage the gas valve. Under the action of the gear, the gas valve rotates. The gas valve rotates to connect the gas storage tank and the receiving box. The flame-retardant gas flows into the receiving box through the gas valve.

[0013] According to the above technical solution, the first tooth block meshes with the gear, the gear meshes with the gas valve, and the gear meshes with the second tooth block. When the gear rotates, it meshes with the second tooth block. Under the action of the gear, the second tooth block moves downward. The movement of the second tooth block drives the baffle plate to move. The movement of the baffle plate closes the receiving box.

[0014] The present invention provides a receiving device suitable for a lithium battery of a new energy vehicle and having a heat dissipation function. It has the following beneficial effects: (1) For the receiving device suitable for the lithium battery of the new energy vehicle and having a heat dissipation function, through the setting of the shock absorption device, the receiving plate, the first connecting block, the first rotating rod, the second connecting block, the sleeve, the fixed shaft and the first limiting groove cooperate with the first limiting block, and the first spring stretches to reduce the impact force.
