Description

Technical Field

[0001] The utility model relates to the technical field of new energy battery shell protection, in particular to an anti-collision buffer structure of a shell of a new energy battery. Background Art

[0002] New energy batteries refer to high-performance, high-reliability batteries used in new energy vehicles, energy storage systems and other fields. Their main features are high energy density, long life, good safety, low cost, etc. New energy batteries include lithium-ion batteries, sodium-ion batteries, iron batteries, etc. Among them, lithium-ion batteries are currently the most widely used new energy batteries. They have the advantages of high energy density, long life, light weight, and small size, and are widely used in electric vehicles, mobile phones, laptops and other fields.

[0003] Most of the existing new energy battery casings protect the new energy batteries inside through their own materials, and the protection effect is poor. When the casing is subjected to a large impact, the impact is still easily transmitted to the battery itself, thereby easily damaging the new energy battery.

[0004] In view of this, Chinese patent CN219226490U discloses a protective shell for protecting new energy batteries. The battery module is placed on an elastic placement plate, which weakens the bottom vibration of the battery module. The elastic force of several springs in the protective component cooperates with the elastic force of the elastic ball to weaken and eliminate the side collision force on the battery module. Two groups of compression springs cooperate to provide auxiliary support for the two groups of long sides of the protective frame, thereby increasing the stability of the two groups of long sides of the protective frame. When the shell is subjected to bumps and vibrations, the battery module can be buffered and protected, thereby minimizing external vibrations to the battery module and improving the safety and reliability of the battery module during long-term use.

[0005] By comparing the above existing documents, the inventor believes that the following defects still exist:

[0006] Although the comparative document can provide buffering protection for the battery module when the shell is impacted by setting the elastic parts, the elastic parts also have elastic potential energy, which can easily cause the protection frame to vibrate continuously during use, affecting the stability of the battery itself. Therefore, we propose a new energy battery shell anti-collision buffer structure to solve the above problems. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides an anti-collision buffer structure for the shell of a new energy battery, which has the advantages of good protection effect, etc., and solves the problem that the prior art uses elastic parts to achieve the protection and buffering effect, which easily affects the stability of the battery itself.

[0008] In order to achieve the above-mentioned purpose of good protection effect, the utility model provides the following technical solutions: a new energy battery shell anti-collision buffer structure, including a shell, the surface of the shell is provided with a protection component for buffering and protecting the shell, the protection component includes a plurality of damping rods fixedly installed on the surface of the shell, and a protective plate is fixedly installed on the side of the damping rod on the same side away from the shell, a first buffer airbag is installed between the protective plate and the shell, a partition is fixedly installed on the inner wall of the shell, a second buffer airbag is installed on the top of the partition, a counterweight is placed between the second buffer airbag and the inner top wall of the shell, and a ventilation hose is connected between the first buffer airbag and the second buffer airbag.

[0009] Furthermore, a shell door is hinged on the front side of the shell, the front protection assembly is installed outside the shell door, and a plurality of heat dissipation openings are opened on the surface of the shell door.

[0010] Furthermore, a rubber plate for placing the new energy battery is fixedly mounted on the inner bottom wall of the shell, and a limiting component for limiting the new energy battery is also provided inside the shell.

[0011] Furthermore, the limit assembly includes two rotating drums respectively rotatably mounted on the inner walls of both sides of the shell, the inner wall of the rotating drum is threadedly mounted with a moving block, one side of the moving block is fixedly mounted with a movable rod extending to the outside of the rotating drum, and the movable rod is fixedly mounted with a limit plate at one end outside the rotating drum.

[0012] Furthermore, the inner wall of the rotating drum is provided with an internal thread, the surface of the moving block is provided with an external thread, and the moving block is threadably connected to the inner wall of the rotating drum via the internal thread and the external thread.

[0013] Furthermore, two slide grooves are provided on the top of the rubber plate, and a sliding block extending into the corresponding slide grooves is fixedly installed on the bottom of the limiting plate.

[0014] Furthermore, anti-skid bases are fixedly installed at the four corners of the bottom of the shell, and anti-skid pads are fixedly installed on the opposite sides of the two limit plates.

[0015] Compared with the prior art, the utility model provides an anti-collision buffer structure for the shell of a new energy battery, which has the following beneficial effects:

[0016] 1. The shell anti-collision buffer structure of the new energy battery has a protective component that is set up. When the shell is impacted, the impact force will first act on the protective plate. When the protective plate is displaced by force, the damping rod will immediately perform buffering and adjustment by extension. At the same time, when the first buffer airbag is squeezed by force, the gas inside it will enter the second buffer airbag through the ventilation hose, thereby lifting the counterweight block. Under the action of the gravity of the counterweight block, the gas injected into the second buffer airbag will return to the first buffer airbag, thereby achieving a reset effect. The mutual cooperation of the protective plate, the damping rod, the first buffer airbag and the second buffer airbag can greatly reduce the impact on the shell, so that the new energy battery inside it is not easily damaged by impact, and the stability is better, which greatly improves the protection effect of the shell.

[0017] 2. The anti-collision buffer structure of the shell of the new energy battery can limit the new energy battery through the setting of the limiting component, so that it is not easy to collide with the inner wall of the shell due to displacement, thereby further improving the protection effect of the new energy battery.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 and Figure 2 , a shell anti-collision buffer structure of a new energy battery, including a shell 1.

[0026] The surface of the housing 1 is provided with a protection component for buffering and protecting the housing 1 .

[0027] The protection assembly includes a plurality of damping rods 2 fixedly mounted on the surface of the shell 1, a protective plate 3 is fixedly mounted on the side of the same-side damping rod 2 away from the shell 1, a first buffer airbag 4 is installed between the protective plate 3 and the shell 1, a partition 5 is fixedly mounted on the inner wall of the shell 1, a second buffer airbag 6 is installed on the top of the partition 5, a counterweight block 7 is placed between the second buffer airbag 6 and the inner top wall of the shell 1, and a ventilation hose 8 is connected between the first buffer airbag 4 and the second buffer airbag 6.

[0028] Among them, when the shell 1 is impacted, the impact force will first act on the protective plate 3. When the protective plate 3 is displaced by the force, the damping rod 2 will immediately perform buffering and adjustment by extension. At the same time, when the first buffer airbag 4 is squeezed by the force, the gas inside it will enter the second buffer airbag 6 through the ventilation hose 8, thereby lifting the counterweight block 7. Under the action of the gravity of the counterweight block 7, the gas injected into the second buffer airbag 6 will return to the first buffer airbag 4, thereby achieving a reset effect. The mutual cooperation of the protective plate 3, the damping rod 2, the first buffer airbag 4 and the second buffer airbag 6 can greatly reduce the impact on the shell 1, so that the new energy battery inside it is not easily damaged by impact, and the stability is better, which greatly improves the protection effect of the shell 1.

[0029] It is worth noting that when the protective plate 3 is not impacted by external force, there is no gas inside the second buffer airbag 6 .

[0030] See also Figure 1 In this embodiment, a shell door 16 is hinged on the front side of the shell 1, and the front side protection component is installed outside the shell door 16. A plurality of heat dissipation openings 17 are opened on the surface of the shell door 16.

[0033] See also Figure 3 and Figure 4 A limiting component for limiting the position of the new energy battery is also provided inside the shell 1.

[0034] In this embodiment, the limiting assembly includes two rotating drums 10 respectively rotatably mounted on the inner walls of both sides of the shell 1, a moving block 11 is threadedly mounted on the inner wall of the rotating drum 10, a movable rod 12 extending to the outside of the rotating drum 10 is fixedly mounted on one side of the moving block 11, a limiting plate 13 is fixedly mounted on one end of the movable rod 12 located outside the rotating drum 10, an internal thread is provided on the inner wall of the rotating drum 10, an external thread is provided on the surface of the moving block 11, and the moving block 11 is threadedly connected to the inner wall of the rotating drum 10 through the internal thread and the external thread.

[0035] The rotating drum 10 is rotated to move the moving block 11, thereby moving the limiting plate 13 through the movable rod 12. When the two limiting plates 13 move in opposite directions, the new energy battery can be limited.

[0036] The new energy battery can be limited by the setting of the limiting component, so that it is not easy to collide with the inner wall of the shell 1 due to displacement, thereby further improving the protection effect of the new energy battery.

[0037] In this embodiment, two slide grooves 15 are formed on the top of the rubber plate 9 , and a slider 14 extending into the corresponding slide grooves 15 is fixedly mounted on the bottom of the limiting plate 13 .

[0038] The slide groove 15 and the slider 14 are provided to limit the limit plate 13 so that the limit plate 13 can move normally when the drum 10 rotates.

[0039] See also Figure 3 In this embodiment, anti-skid bases are fixedly installed at the four corners of the bottom of the shell 1, and anti-skid pads 18 are fixedly installed on the opposite sides of the two limiting plates 13.

[0040] Among them, by providing the anti-slip pad 18, the two limiting plates 13 have greater friction and are more stable when limiting the new energy battery.

[0041] It is worth noting that the present application also provides a second embodiment, as shown in FIG. Figure 5 As shown;

[0042] That is, each first buffer airbag 4 corresponds to a second buffer airbag 6 and a counterweight block 7, which can also achieve the protection effect shown in the present application.

[0043] When the present embodiment is in use, the shell door 16 is opened, the new energy battery is placed on the rubber plate 9, and the rotating drum 10 is rotated to move the moving block 11, thereby moving the limit plate 13 through the movable rod 12, and the new energy battery can be limited when the two limit plates 13 move in opposite directions; when the shell 1 is impacted, the impact force will first act on the protective plate 3, and when the protective plate 3 is displaced by force, the damping rod 2 will be adjusted by buffering by extension in the first time, and at the same time, when the first buffer airbag 4 is squeezed by force, the gas inside it will enter the second buffer airbag 6 through the ventilation hose 8, thereby lifting the counterweight block 7, and under the gravity of the counterweight block 7, the gas injected into the second buffer airbag 6 will return to the first buffer airbag 4, thereby achieving a reset effect, and the mutual cooperation of the protective plate 3, the damping rod 2, the first buffer airbag 4 and the second buffer airbag 6 can greatly reduce the impact on the shell 1, so that the new energy battery inside it is not easily damaged by impact, and the stability is better, which greatly improves the protection effect of the shell 1.
