Description

Technical Field

[0001] The invention relates to the technical field of energy batteries, and in particular to an ultra-high rate battery power supply device. Background Art

[0002] Existing high-power power supplies generally have power batteries integrated inside, and then use the power supply to drive specific products. For example, in new energy vehicles, high-power power supplies can be used as the driving power supply for the vehicle computer. However, for high-power power supplies, due to their high energy density, they have higher requirements for safety. Existing ultra-high-rate battery power supply devices require them to have a certain impact resistance. In order to improve the impact resistance of ultra-high-rate battery power supply devices, existing technologies generally adopt the method of enhancing protective armor. However, this method still cannot prevent the power battery from spontaneously igniting due to the impact when a collision occurs. Therefore, how to avoid the spontaneous combustion of the device due to the impact to the greatest extent is a topic that urgently needs to be studied in the industry. Summary of the invention

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] It should be noted that, although the functional modules are divided in the system schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the system or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0023] Please refer to Figure 1 and Figure 3 , Figure 1 It is a schematic diagram of the cross-sectional structure of an ultra-high rate battery power supply device. Figure 3 It is a three-dimensional structural schematic diagram of an ultra-high rate battery power supply device.

[0024] The present application mainly designs a reliable structure to prevent the battery pack 500 from being damaged and burned due to high impact when the front of the ultra-high rate battery power supply device is hit, thereby maximizing the safety factor of the ultra-high rate battery power supply device.

[0025] To achieve this goal, the present application provides an ultra-high rate battery power device, the structure of which includes: a metal outer shell 100, a metal inner shell 200, a push plate 400, a cover plate 700, an elastic member 300 and a battery cell group 500.

[0026] The metal shell 100 serves as an outer protective shell of the entire ultra-high-rate battery power source device, and other components of the ultra-high-rate battery power source device are mounted by providing a first accommodating compartment.

[0027] The metal inner shell 200, the push plate 400, the elastic member 300 and the battery pack 500 are all arranged in the first accommodation chamber. The metal inner shell 200 is arranged in the first accommodation chamber in a sleeve-type manner. A buffer space 600 is provided between the front side wall of the metal outer shell 100 and the front side wall of the metal inner shell 200.

[0028] The metal inner shell 200 is provided with a second accommodation chamber, through which the battery cell group 500 is accommodated. The push plate 400 is located between the front side wall of the metal inner shell 200 and the front side of the battery cell group 500; the front end of the elastic member 300 is connected to the front side wall of the metal inner shell 200, and the rear end of the elastic member 300 is connected to the push plate 400; the cover plate 700 is used to cover the first accommodation chamber, and the rear side wall of the metal inner shell 200 is in contact with the cover plate 700.

[0029] This structure is mainly used to protect against front impact. When the front of this high-rate battery power device is hit hard, the metal shell 100 is broken under the action of the impact force, and the impact object passes through the front side wall of the metal shell 100. The front side wall of the metal shell 100 collides with the front side wall of the metal inner shell 200. The metal inner shell 200 moves backward under the action of the collision force. After the front side wall of the metal inner shell 200 moves, it compresses the elastic member 300, so that the elastic member 300 is in a compressed state. At the same time, the rear side wall of the metal inner shell 200 pushes the cover plate 700 by moving backward. Under the action of the rear side wall of the metal inner shell 200, the cover plate 700 is pushed open, so that the cover can be separated from the metal shell 100.

[0030] After being compressed to a certain extent, the elastic member 300 will rebound and recover. During the rebound recovery process of the compressed member, the push plate 400 generates a driving force. The push plate 400 pushes the battery cell group 500. Under the action of the driving force, the battery cell group 500 is pushed out. The battery cell group 500 moves backward, and under the action of the driving force, the battery cell group 500 is pushed out of the first storage compartment. Thus, it is away from the impact area.

[0031] Of course, the impact force may continue to damage the metal shell 100, but since the battery pack 500 is far away from the metal shell 100, all structures of the metal shell 100 can resist the impact force. Therefore, the battery pack 500 is protected by the entire metal shell 100. The impact force on the battery pack 500 is reduced to the greatest extent. Therefore, the safety factor of the entire ultra-high rate battery power device is improved.

[0032] The present invention uses the elastic member 300 to absorb the impact force, and at the same time, uses the metal inner shell 200 to break the cover plate 700 in advance. When the elastic member 300 rebounds, the battery group 500 can be pushed away from the metal shell 100 through the push plate 400. By pushing the battery group 500 away from the metal shell 100, the metal shell 100 can resist the impact force with all its structures. As a result, the battery group 500 is protected by the entire metal shell 100. The impact force on the battery group 500 is reduced to the greatest extent. As a result, the safety factor of the entire ultra-high rate battery power device is improved.

[0033] In some further specific embodiments, there is a step between the cover and the rear side wall of the metal housing 100 .

[0034] The elastic member 300 needs to absorb the impact force and then release the impact force. It plays a role of time buffering for the impact force acting on the battery cell group 500. Before the elastic member 300 is released, the rear side wall of the metal inner shell 200 needs to complete the pushing of the cover plate 700. Therefore, for the elastic member 300, it can be realized by a spring group. Because the elastic coefficient of the spring group is easy to control, the function of the elastic member 300 can be realized by controlling the elastic coefficient of the spring group.

[0035] In order to prevent the front side wall of the metal inner shell 200 from being directly damaged by penetration due to excessive impact force, so that the metal inner shell 200 can move backwards well, in some further specific embodiments, a soft material component layer is filled in the buffer space 600. The soft material component layer is used as a buffer to prevent the front side wall of the metal inner shell 200 from being directly damaged by penetration due to excessive impact force.

[0036] Regarding the soft material component layer, in some further specific embodiments, the soft material component layer is a rubber material component layer.

[0037] In some further specific embodiments, a lubricating oil layer is provided at the socket joint between the outer wall of the metal inner shell 200 and the inner wall of the metal outer shell 100. The lubricating oil layer reduces the friction between the metal inner shell 200 and the metal outer shell 100, so that the metal inner shell 200 can move backward as quickly as possible under the impact force to push the cover plate 700 away.

[0038] Figure 2 It is a schematic diagram of the enlarged structure of the positions of the first elastic pin and the first slot of the ultra-high rate battery power supply device.

[0039] Regarding the connection method between the cover plate 700 and the metal shell 100, in some further specific embodiments, the upper side wall of the metal shell 100 is provided with a first elastic pin 101, and the upper part of the cover plate 700 is provided with a first slot 701, and the first elastic pin 101 is inserted into the first slot 701.

[0040] The lower side wall of the metal shell 100 is provided with a second elastic pin 102 , and the lower portion of the cover plate 700 is provided with a second slot 702 , into which the second elastic pin 102 is inserted.

[0041] The cover plate 700 connects the upper part of the cover plate 700 to the metal housing 100 by placing the first slot 701 on the first latch. The cover plate 700 connects the lower part of the cover plate 700 to the metal housing 100 by placing the second slot 702 on the second latch. The latch connection makes it easier for workers to cover the first containing chamber with the cover plate 700 during production of the ultra-high rate battery power device. This facilitates the production and manufacture of the ultra-high rate battery power device.

[0042] In order to increase the impact resistance of the high-rate battery power device, in some further specific embodiments, reinforcing ribs 110 are provided on the outer peripheral wall of the metal shell 100 .

[0043] When the high-rate battery power device is actually used, it will be fixedly installed. The front side wall of the metal shell 100 is facing the side that is easily impacted. A certain space will be left behind the metal shell 100 to facilitate the push-out of the battery pack 500. In order to facilitate the fixation of the high-rate battery power device, in some further specific embodiments, the metal shell 100 is provided with a mounting ear 800. In some further specific embodiments, the mounting ear 800 is provided with a through hole 810.

In addition, the above description of the present application is based on the embodiments foreseeable by the inventor, and its purpose is to provide a useful description, and those non-substantial changes to the present application that have not yet been foreseen may still represent equivalent changes to the present application.
