Description

Battery loading device

[0001] The present invention relates to a battery loading device, and more particularly, to a battery loading device capable of increasing transport efficiency through a plurality of side covers capable of being folded inward or outward.

[0002]

[0003] With the recent increase in environmental concerns, the number of electrified vehicles powered by electric motors is on the rise.

[0004] Accordingly, batteries are required to operate electric vehicles, and when transporting batteries overseas, a battery loading device is essential to load multiple batteries vertically.

[0005] Typically, when connecting multiple battery cells in series or parallel to form a battery pack, a battery module composed of multiple battery cells is first constructed, and then other components are added using the battery module to form the battery pack. At this time, the battery pack is configured as a battery loading device with multiple batteries loaded for household use or industrial use, depending on various voltage and capacity requirements.

[0006] Conventional battery loading devices that secure batteries through welding typically require single-use disposal, leading to environmental issues and reduced transport efficiency. Furthermore, even battery loading devices that only allow for inward folding have the disadvantage of creating a certain amount of play in the Z-axis, reducing transport efficiency.

[0007] Accordingly, there is a need for a method to increase transport efficiency through multiple side covers that can be folded inward or outward.

[0008] In addition, there is KR 10-2023-0103431 A as a prior art related to this.

[0009]

[0010] The matters described as background technology above are only intended to enhance understanding of the background of the present invention, and should not be taken as an admission that they correspond to prior art already known to those skilled in the art.

[0011]

[0012] The present invention provides a battery loading device capable of increasing transport efficiency through a plurality of side covers capable of being folded inward or outward.

[0013]

[0014] The technical problems to be achieved in the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0015]

[0016] As a means for solving the above technical problem, the present invention comprises a battery loading device including: a loading base that supports the lower side of a battery and regulates the lateral position of the battery; a base bracket that extends upward from each corner of the loading base and has a fixing groove formed on the upper surface; and a plurality of side covers that are provided on the outer side of the loading base and are formed to be foldable inward or outward by being connected to both sides of the base bracket, and are fixed to the base bracket when fastened to the fixing groove so that the side of the battery is covered.

[0017] For example, a plurality of fixing portions are formed on the upper surface of the loading base, and the lateral position of the battery can be regulated by supporting the edges of the battery by the fixing portions.

[0018] For example, it may further include a plurality of stoppers provided on the inner side of the side cover and regulating the vertical position of the battery when the battery is loaded.

[0019] For example, in the loading base, the side cover is folded inward, and a plurality of indentations are formed by being indented downward at a point facing the loading base, and the stopper can be folded together when the side cover is folded inward and be seated in the indentations.

[0020] For example, through holes extending vertically are formed on both sides of the base bracket, and side pins protruding from both sides of the side cover are inserted into the through holes, thereby connecting the side cover to both sides of the base bracket.

[0021] For example, the through hole is formed in a vertically elongated shape on both sides of the base bracket, the side pin is inserted into the through hole and moves vertically along with the vertical movement of the side cover, and the side cover can be formed so that it can be folded inward or outward while the side pin is moved upward.

[0022] For example, the side cover may be parallel to the loading base when folded inward, and may be perpendicular to the loading base when fastened to the fixing groove and fixed to the base bracket.

[0023] For example, a first fixing device is formed on the lower part of the outer surface of the side cover to be fixed to the loading base, and the side cover can be fixed to the loading base and the first fixing device while being fixed to the base bracket.

[0024] For example, it may further include an upper cover that is arranged to face the loading base and covers the upper portion of the battery when the battery is loaded.

[0025] For example, a side cover may be formed with a second fixing device on the upper side to be fixed to the upper cover, and the upper cover may be fixed to the side cover and the second fixing device while being placed on the upper side of a plurality of side covers.

[0026] For example, protrusions protruding outward toward the base bracket are formed at both ends of the plurality of side covers, and a pair of fixing grooves are formed in different directions based on the corners of the loading base, and the protrusions are inserted into the fixing grooves so that the side covers cover the sides of the battery.

[0027] For example, in a state where a protrusion formed on a side cover is inserted into a fixing groove, both ends of a plurality of side covers are in contact with ends of different side covers, and a third fixing device is formed on the end of at least one side cover, and adjacent side covers can be fixed to each other through the third fixing device.

[0028] For example, the loading base, base bracket, multiple side covers and upper covers can be made of flame retardant material.

[0029]

[0030] According to the battery loading device of the present invention, the weight of the battery loading device itself can be reduced through a plurality of side covers that can be folded inward or outward, thereby increasing transportation efficiency.

[0031] Additionally, the side cover configuration eliminates the need for separate welding on the battery loading device, enabling the reuse of the battery loading device, and prevents the spread of fire to the batteries loaded inside the loading device in the event of an external fire.

[0032]

[0033] The effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present invention belongs from the description below.

[0053] According to one embodiment of the present invention, it is proposed to increase transport efficiency by reducing the weight of the battery loading device itself through a plurality of side covers that can be folded inward or outward.

[0054] Fig. 1 is a drawing illustrating a battery loading device according to one embodiment of the present invention. Fig. 1 mainly illustrates components related to this embodiment, and it is obvious that an actual battery loading device may include fewer or more components.

[0055]

[0056] Referring to FIG. 1, a battery loading device (100) according to one embodiment may include a loading base (101), a base bracket (111), and a side cover (110). The battery loading device (100) is installed above a side rack (200) having wheels (300) on the lower surface, so that the side cover (110) can be folded outward. This will be described later.

[0057] The loading base (101) supports the lower side of the battery (10) and regulates the lateral position of the battery (10). More specifically, a cushion part (131) provided on the upper surface of the loading base (101) supports the loaded battery (10) from the lower side, and a fixing part (130) provided on the upper surface can support the battery (10) from the side. A plurality of fixing parts (130) are provided to support the edge of the battery (10) along the shape of the battery (10), thereby regulating the X, Y-axis direction, i.e., the lateral position of the battery (10). The fixing part (130) is formed of an elastic material such as a urethane material, so that even when an external impact is applied while the battery (10) is loaded, the impact transmitted to the battery (10) can be absorbed.

[0058] In addition, the base bracket (111) extends upward from each corner of the loading base (101), and fixing grooves (111a, 111b) are formed on the upper surface. As will be described later, the fixing grooves (111a, 111b) are connected to the side cover (110) to prevent the side cover (110) from folding together with the stopper (120) when the battery (10) is loaded.

[0059] A plurality of side covers (110) are provided on the outer side of the loading base (101), and are formed to be foldable inward or outward by being connected to both sides of the base bracket (111). In addition, the side covers (110) are fixed to the base bracket (111) when fastened to the fixing groove, thereby covering the side of the battery (10). This will be described with reference to FIGS. 2 and 3.

[0060] The outer folding of the side cover (110) in the battery loading device (100) is a structure for loading or unloading the battery (10), and the inner folding of the side cover (110) is performed to reduce the overall volume when recovering the battery loading device (100) after unloading the battery (10). To explain in more detail,

[0061] Figures 2 and 3 are drawings showing a state in which the side cover (110) is folded outward and inward, respectively, according to one embodiment of the present invention.

[0062] Referring to FIGS. 2 and 3, when multiple side covers (110) are folded outward or inward, the base bracket (111) can remain fixed to each corner of the loading base (101). At this time, when the side cover (110) is folded outward, the side cover (110) can form an angle of 270 degrees based on the state in which it is folded inward.

[0063] FIG. 4 is a drawing showing an upper cover (140) covering the upper portion of a battery (10) according to one embodiment of the present invention.

[0064] Referring to FIG. 4, the upper cover (140) is provided to face the loading base (101) and can cover the upper portion of the battery (10) when the battery (10) is loaded. At this time, the upper cover (140) is mounted on the upper portion of a plurality of side covers (110) and the side covers (110) can be fixed to the side covers (110) through a second fixing device (113) formed on the upper portion of the outer surface. Since the upper portion of the battery (10) is covered by the upper cover (140), it is possible to prevent the fire from spreading to the battery (10) loaded inside the loading device when a fire occurs from the outside.

[0065] In addition, the loading base (101), base bracket (111), multiple side covers (110) and upper cover (140) may be made of flame retardant material to prevent the spread of fire to the battery (10).

[0066] Fig. 5 is a drawing showing a stopper (120) that regulates the vertical position of a battery (10) according to one embodiment of the present invention. In addition, Fig. 6 is a drawing showing a battery loading device (100) according to one embodiment of the present invention as viewed from the side.

[0067] Referring to FIGS. 5 and 6, a plurality of stoppers (120) may be provided on the inner surface of the side cover (110). Through the configuration of the stoppers (120), the Z-axis direction, i.e., the vertical position of the battery (10) when the battery (10) is loaded can be regulated. A flange portion (121) is formed at the end of the stopper (120) to press downward the fastening portion (11) of the battery (10).

[0068] At this time, the side cover (110) is parallel to the loading base (101) when folded inward, and can be perpendicular to the loading base (101) when fixed to the fixing groove and fixed to the base bracket (111).

[0069] FIG. 7 and FIG. 8 are drawings showing the connection structure of the base bracket (111) and the side cover (110) and the connection structure of the loading base (101) and the side cover (110) according to one embodiment of the present invention, respectively.

[0070] Referring to Fig. 7, a structure in which the upper portion of the side cover (110) protrudes outward can be confirmed. In the protruding structure, a pin-shaped protrusion (110b) protrudes downward again and is fastened to a second fixing groove (111b) formed on the upper surface of the base bracket (111), through which the side cover (110) and the base bracket (111) can be connected to each other. Through this structure, the side cover (110) can be fixed in a state in which it is not folded inward or outward, and the battery (10) loaded in the internal space can be protected from external impact.

[0071] Referring to Fig. 8, a first fixing device (112) is formed at the lower end of the outer surface of the side cover (110) to be fixed to the loading base (101). At this time, the side cover (110) can be fixed to the loading base (101) through the first fixing device (112) in a state where it is fixed to the base bracket (111). The first fixing device (112) is composed of a latch portion (112a) and a handle portion (112b), and the user can press downward to lower the latch portion (112a) while moving the handle portion (112b), thereby fixing the loading base (101) to the side cover (110). Through this method, welding of each component in the battery loading device (100) of the present invention becomes unnecessary, and thus the battery loading device (100) can be reused.

[0072] Meanwhile, referring to FIG. 7, a pin-shaped protrusion (110b) protrudes downward from the upper portion of the side cover (110) and is fastened to a second fixing groove (111b) formed on the upper surface of the base bracket (111), thereby covering one side of the battery loading device (100).

[0073] At this time, a pin-shaped protrusion (110a) protrudes downward from the upper part of another side cover (110) that is responsible for covering the adjacent side, and is fastened to the first fixing groove (111a) formed on the upper surface of the base bracket (111), thereby covering the other side of the battery loading device (100).

[0074] In this way, the fixed grooves (111a, 111b) may be formed in different directions based on the corners of the loading base (101), and the fixed grooves may include a first fixed groove (111a) and a second fixed groove (111b).

[0075] Accordingly, in each of the fixing grooves (111a, 111b), protrusions (110a, 110b) protruding outward toward the base bracket (111) at both ends of the plurality of side covers (110) can be inserted into each of the fixing grooves (111a, 111b), and each of the side covers (110) can cover the battery from different sides.

[0076] In this way, when the protrusions (110a, 110b) formed on the side cover (110) are inserted into the fixing grooves (111a, 111b), both ends of the plurality of side covers (110) come into contact with the ends of different side covers, and this is illustrated in FIG. 9.

[0077] Referring to FIG. 9, a third fixing device (114) is formed at the end of one or more side covers (110), and adjacent side covers (110) can be fixed to each other through the third fixing device (114). The third fixing device (114) is composed of a clasp portion (114a) and a handle portion (114b), and a user can fix or release adjacent side covers (110) by pressing the clasp portion (114a) to move left and right while moving the handle portion (114b). Through this method, welding of each component in the battery loading device (100) of the present invention becomes unnecessary, and thus, the battery loading device (100) can be reused.

[0078]

[0079] FIG. 10 is a drawing showing a state in which a side fin (110c) according to one embodiment of the present invention is inserted into a through hole (111c) so that the side cover (110) can be folded inward or outward.

[0080] Referring to Fig. 10, the connection structure with the base bracket (111) is very important in order for the side cover (110) to be folded inward or outward. This enables the side cover (110) to be folded inward or outward through a through hole (111c) formed vertically and elongated from both sides of the base bracket (111) and a side pin (110c) formed protruding from both sides of the side cover (110). More specifically, the side pin (110c) formed protruding from both sides of the side cover (110) is inserted into the through hole (111c), thereby connecting the side cover (110) to both sides of the base bracket (111). Here, the through hole (111c) is formed in a vertically elongated shape on both sides of the base bracket (111), and the side pin (110c) is inserted into the through hole (111c) so that the side cover (110) moves vertically and rotates 270 degrees with respect to the base bracket (111). At this time, the side cover (110) can be folded inward or outward while the side pin (110c) is moved upward.

[0081] FIG. 11 is a drawing showing a recessed portion (101a) recessed downward in a loading base (101) according to one embodiment of the present invention.

[0082] Referring to Fig. 11, a plurality of recessed portions (101a) may be formed by recessing downward at points where the side cover (110) is folded inward on the loading base (101). At this time, the stopper (120) may be folded together with the side cover (110) when it is folded inward and may be seated in the recessed portions (101a). In this way, when the side cover (110) is folded inward through the recessed portions (101a) formed in the Z-axis direction based on the loading base (101), the height of the battery loading device (100) is lowered, and as a result, the volume of the battery loading device (100) itself can be minimized, so that the efficiency of transporting the battery (10) can be greatly increased.

[0083] According to the embodiments of the present invention described thus far, the weight of the battery loading device itself can be reduced through the use of multiple side covers that can be folded inward or outward, thereby increasing transport efficiency. Furthermore, the side cover configuration eliminates the need for separate welding on the battery loading device, enabling the device to be reused. Furthermore, in the event of an external fire, the spread of fire to the batteries loaded within the loading device can be prevented.

[0084]

[0085] Although the present invention has been illustrated and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that the present invention may be variously improved and modified without departing from the technical spirit of the invention as defined by the following claims.
