Description

Technical Field

[0001] This disclosure relates to a high-voltage battery bracket for vehicles that improves usability. Background Technology

[0002] The statements in this section are provided only as background information in connection with this disclosure and do not constitute prior art.

[0003] In recent years, electric vehicles have been developed as an environmentally friendly technology that addresses issues such as energy consumption. Electric vehicles operate via an electric motor, which receives electrical energy from a battery and outputs power. Therefore, electric vehicles are considered environmentally friendly vehicles due to their advantages: no carbon dioxide emissions, very low noise, and the high energy efficiency of electric motors compared to conventional engines.

[0004] Such environmentally friendly vehicles are also being developed into electric buses. Because multiple high-voltage batteries and electrical and electronic components are housed in large vehicles (such as electric buses), more space is required to accommodate them.

[0005] Furthermore, the maintainability of electrical and electronic components should be ensured. However, we have found that due to the lack of consideration for maintainability, there are problems with the maintenance of electrical and electronic components.

[0006] The foregoing is intended only to help understand the background of this disclosure and is not intended to imply that the foregoing content of this disclosure falls within the scope of related technologies known to those skilled in the art. Summary of the Invention

[0014] In another aspect of this disclosure, the engaging member is formed in a corresponding support panel among a plurality of support panels and engages with a corresponding fixing member among the fixing members, and the engaging member extends vertically. In other forms, a through-hole through which the engaging member passes may be formed in a corresponding first battery frame among a pair of first battery frames.

[0015] The sub-frame may include: a pair of first sub-frames extending in a front-rear direction, one or more second sub-frames extending inward along one of the pair of first sub-frames facing each other, and a third sub-frame spaced in the front-rear direction and extending toward and connecting to the pair of first battery frames.

[0016] Each of a pair of first subframes, one or more second subframes, and a third subframe may have a closed cross-section, and reinforcing ribs may be formed at the connection between the pair of first subframes and the third subframes.

[0017] The pair of first battery frames may also include a bonding panel disposed at the connection portion of the third sub-frame and configured to form a flat surface, and the bonding panel may be attached to the pair of first battery frames and attached to the third sub-frame via a fastening member.

[0018] A connector configured to extend vertically and engage with a fixing component can be formed in the bonding panel, and an opening through which the connector passes can be formed in a pair of first battery frames.

[0019] Multiple detachable brackets protruding in the facing direction are spaced apart on a pair of first sub-frames in the extending direction of the first sub-frames, and detachable brackets are inserted between the pair of first sub-frames and engage with and fix to the multiple detachable brackets.

[0020] The detachable bracket can be constructed as a polygon by connecting multiple detachable frames, and the multiple detachable brackets and multiple detachable frames can be connected by multiple fixing components.

[0035] In the following description, an exemplary embodiment of a high-voltage battery holder for a vehicle according to the present disclosure will be described with reference to the accompanying drawings.

Figure 9 and Figure 10 It is used to describe the installation Figure 1 The diagram shows the sub-bracket and detachable bracket for the high-voltage battery used in the vehicle.

[0037] like Figures 1 to 4As shown, the high-voltage battery bracket for a vehicle according to this disclosure includes: a main bracket 200, which is connected to the vehicle body frame 100 and to which the high-voltage battery 10 is fixed; a sub-bracket 300, which is connected to the upper or lower part of the main bracket 200 and, when connected to the main bracket 200, forms a space therein for accommodating electrical and electronic components 20, and is configured to be open in the vertical direction; and a removable bracket 400, which is removably and vertically mounted in the sub-bracket 300, to which the electrical and electronic components 20 are connected. The electrical and electronic components 20 may include various electronic devices desired in electric or hybrid vehicles, such as low-voltage DC-DC converters (LDC), inverters, on-board chargers (OBC), etc.

[0038] This disclosure includes a main bracket 200, a sub-bracket 300, and a removable bracket 400, with the main bracket 200 connected to the vehicle body frame 100. Here, a high-voltage battery 10 is mounted on and fixed to the main bracket 200, and electrical and electronic components 20 are mounted on and fixed to the removable bracket 400. The removable bracket 400 is detachably mounted on the sub-bracket 300, which is connected to the main bracket 200. Therefore, during maintenance of the electrical and electronic components 20, the removable bracket 400 is separated from the sub-bracket 300 to allow for maintenance of the electrical and electronic components 20.

[0039] As described above, in this disclosure, the high-voltage battery 10 and the electrical and electronic components 20 are secured by a main bracket 200, a sub-bracket 300, and a removable bracket 400, and the structure is configured such that the high-voltage battery 10 and the electrical and electronic components 20 are arranged in two stages on the upper and lower sides of the vehicle frame 100. Furthermore, since the electrical and electronic components 20, which require relatively frequent maintenance, are secured to the removable bracket 400, the removable bracket 400 is separated from the sub-bracket 300 to allow for maintenance of the electrical and electronic components 20, thereby improving maintainability.

[0040] Meanwhile, the high-voltage battery 10 is fixed to the upper part of the main bracket 200, the sub-bracket 300 is connected to the lower part of the main bracket 200, and the detachable bracket 400 is inserted below the sub-bracket 300 and then connected to the sub-bracket 300. Therefore, electrical and electronic components 20 can be disposed between the main bracket 200 and the sub-bracket 300.

[0041] When the high-voltage battery 10 and electrical and electronic components 20 are applied to large vehicles (such as large buses), the high-voltage battery 10 and electrical and electronic components 20 are mounted in the body frame 100 on the lower side of the large vehicle, such that the sub-bracket 300 and the removable bracket 400 are positioned below the main bracket 200. That is, the high-voltage battery 10 is fixed to the upper part of the main bracket 200, and the sub-bracket 300 is connected to the lower part of the main bracket 200, thus ensuring space for the electrical and electronic components 20. The removable bracket 400, to which the electrical and electronic components 20 are fixed, moves upward from the lower side of the sub-bracket 300 to engage with the sub-bracket 300.

[0042] As described above, since the high-voltage battery 10 is fixed to the main bracket 200 and the electrical and electronic components 20 are fixed below the main bracket 200, the high-voltage battery 10 and the electrical and electronic components 20 can be configured as a single module structure. Furthermore, when maintenance of the electrical and electronic components 20 is required, the detachable bracket 400 separates downwards from the sub-bracket 300 to allow for maintenance of the electrical and electronic components 20, thereby improving maintainability.

[0043] For the purpose of describing this disclosure in detail, as Figure 5 As shown, the main bracket 200 may include: a pair of first battery frames 210 extending in a front-rear direction; and a plurality of second battery frames 220, which are arranged to be spaced apart in the extending direction of the first battery frames 210 and extend inward in a direction in which the first battery frames 210 face each other.

[0044] The first battery frame 210 and the second battery frame 220 can be formed with closed cross sections. Therefore, as the cross section coefficient of the first battery frame 210 and the second battery frame 220 increases, their resistance increases to ensure rigidity.

[0045] As described above, the main bracket 200 includes a pair of first battery frames 210 and a plurality of second battery frames 220. Since the pair of first battery frames 210 and the plurality of second battery frames 220 are vertically connected, a quadrilateral space can be formed between them. The main bracket 200 can be configured to have a cross-section. However, because a space is formed between the pair of first battery frames 210 and the plurality of second battery frames 220, the total weight of the main bracket 200 is reduced, and its rigidity is also ensured.

[0046] Here, the number of second battery frames 220 and the spacing between them can be set according to the required rigidity of the main bracket 200.

[0047] At the same time, such as Figure 2 and Figure 6As shown, the vehicle body frame 100 may include: a pair of side frames 110 extending in a longitudinal direction; and a plurality of fixing brackets 120 formed on the pair of side frames 110 and extending inward so as to face each other and be spaced apart from each other. A first battery frame 210 may be disposed between the side frames 110 and may form a connector 211 that mates with the fixing brackets 120. The connector 211 and the fixing brackets 120 may be connected by a fixing member 30 so that the main bracket 200 can be fixed to the side frames 110 constituting the vehicle body frame 100.

[0048] As in Figure 6 As can be seen, the mounting bracket 120 protrudes from the side frame 110 into the main bracket 200 because it is bent in an "L" shape. Since the connector 211 extends from the first battery frame 210 to match the mounting bracket 120, the fixing member 30 passes vertically through the mounting bracket 120 and the connector 211 to connect the mounting bracket 120 to the connector 211.

[0049] Here, the fixing component 30 may be composed of bolts, and nut holes for bolt engagement may be formed in the fixing bracket 120 and the connector 211. In order to separate the main bracket 200 from the body frame 100 downward, the fixing component 30 may be engaged by inserting from the lower side to the upper side of the body frame 100.

[0050] In addition, a reinforcing collar 211a may be provided in the connector 211 to assist the rigidity of the connector 211. The reinforcing collar extends vertically, passes through the fixing member 30, and is made of a rigid material.

[0051] At the same time, such as Figure 5 and Figure 7 As shown, the first battery frame 210 also includes a support panel 212, which is formed with a polygonal or circular cross-section, and the high-voltage battery 10 is disposed on the support panel. The support panel 212 can be connected to the first battery frame 210, and multiple support panels 212 can be arranged in the length direction of the first battery frame 210. The high-voltage battery 10 and the support panel 212 can be connected by a fixing member 30.

[0052] As described above, the support panel 212 on which the high-voltage battery 10 is mounted is disposed in the first battery frame 210 and is formed to have a predetermined cross-sectional area, thereby enhancing the rigidity of the main bracket 200 and stably supporting the high-voltage battery 10 to be fixed.

[0053] Here, a plurality of support panels 212 are provided along the length of the first battery frame 210. The plurality of support panels 212 may be provided at the position in the first battery frame 210 where the second battery frame 220 is connected and a connector 211 is formed, and a greater number of support panels 212 may be provided according to the desired rigidity.

[0054] A vertically extending engagement member 212a, which engages with the fixing member 30, may be formed in the support panel 212, and a through hole 213 through which the engagement member 212a passes may be formed in the first battery frame 210. Therefore, when the support panel 212 is connected to the first battery frame 210, the engagement member 212a passes through the through hole 213 to be inserted into the first battery frame 210, so that the support panel 212 can be tightly connected to the upper part of the first battery frame 210.

[0055] Here, the fixing member 30 may be made of bolts, and a nut hole may be formed in the engaging member 212a so that the fixing member 30 can be bolted together.

[0056] At the same time, such as Figure 8 As shown, the sub-bracket 300 may include a pair of first sub-frames 310 extending along the first battery frame 210 (i.e., in the front-rear direction), one or more second sub-frames 320 extending in a direction facing the first sub-frames 310 (i.e., inward direction), and third sub-frames 330, which are arranged to be spaced apart in the direction in which the pair of first sub-frames 310 extend and extend toward the first battery frame 210 for connection thereto.

[0057] The first sub-frame 310, the second sub-frame 320, and the third sub-frame 330 form closed cross-sections, and therefore their section modulus is increased to increase resistance and ensure rigidity. Reinforcing ribs 300a are formed at the connection points of the first sub-frame 310 and the third sub-frame 330 to increase the rigidity of the connection points of each sub-frame.

[0058] As described above, the sub-bracket 300 includes a pair of first sub-frames 310 and a plurality of second sub-frames 320, and since the pair of first sub-frames 310 are vertically connected to the plurality of second sub-frames 320, a quadrilateral space can be formed between the pair of first sub-frames 310 and the plurality of second sub-frames 320.

[0059] Here, the number of second sub-frames 320 and the spacing between them can be set according to the required rigidity of the sub-bracket 300, and the connection shape of the first sub-frame 310 and the second sub-frame 320 can be determined in order to allow the electrical and electronic components 20 with the greatest weight or relatively low maintenance needs to be fixed. For example, as Figure 9 As shown, the OBC in the electrical and electronic component 20 can be fixed to the sub-bracket 300, and the second sub-frame 320 can be connected to the first sub-frame 310 at the location where the OBC is fixed, so as to ensure rigidity.

[0060] At the same time, such as Figure 10 As shown, the first battery frame 210 also includes a connecting panel 214, which is disposed at the connection portion of the third sub-frame 330 and is formed to form a flat surface. The connecting panel 214 can be connected to the first battery frame 210 and can be connected to the third sub-frame 330 via the fixing member 30.

[0061] As described above, the connecting panel 214 is disposed at a portion of the third sub-frame 330 of the connecting sub-bracket 300 in the first battery frame 210 and is formed to have a predetermined cross-sectional area, thereby enhancing the rigidity at the connection portion of the first battery frame 210 and the third sub-frame 330.

[0062] Here, a connector 214a extending vertically and engaging with the fixing member 30 can be formed in the connecting panel 214, and an opening 215 through which the connector 214a passes can be formed in the first battery frame 210. Therefore, the connecting panel 214 can be connected to the lower part of the first battery frame 210 while being connected to the first battery frame 210.

[0063] Here, the fixing member 30 may be made of bolts, and a nut hole may be formed in the connector 214a so that the fixing member 30 can be bolted together.

[0064] At the same time, such as Figure 8 and Figure 9 As shown, a plurality of detachable brackets 311 may be formed in the first sub-frame 310. These detachable brackets protrude in a direction facing each other and are spaced apart in the extension direction of the first sub-frame 310. A detachable bracket 400 may be inserted between the first sub-frame 310 and engage with and be fixed to the plurality of detachable brackets 311.

[0065] As described above, the detachable bracket 311 protrudes from the upper part of the first sub-frame 310 toward the detachable bracket 400 to match the detachable bracket 400, such that the detachable bracket 311 can be secured to the sub-bracket 300 by the fixing member 30. Here, in order to securely fix the detachable bracket 400, the detachable bracket 400 can be engaged with and fixed to these detachable brackets by a plurality of detachable brackets 311, and the connection points and the number of connections can be set to evenly distribute the load according to the shape of the detachable bracket 400.

[0066] Here, the detachable bracket 400 can be formed into a polygon by connecting multiple detachable frames 410, and the detachable bracket 311 and the detachable frame 410 can be connected by the fixing member 30. Here, the surface of the detachable frame 410 opposite to the surface on which the electrical and electronic components 20 are fixed is formed to be open, thereby ensuring rigidity and reducing weight.

[0067] In this disclosure, since the main bracket 200 and the sub-bracket 300 are formed into quadrilateral shapes, the detachable bracket 400 can also be formed into a quadrilateral shape by vertically connecting multiple detachable frames 410. Therefore, by connecting the detachable frame 410 to the detachable bracket 311 formed in the first sub-frame 310 using the fixing member 30, the detachable bracket 400 can be fixed to the sub-bracket 300.

[0068] Here, the fixing member 30 may be made of bolts, and a nut hole may be formed in the upper part of the removable frame 410 for engagement with the bolts. In order to separate the removable bracket 400 downward from the sub-bracket 300, the fixing member 30 may be engaged by insertion from the lower side to the upper side of the sub-bracket 300.

[0069] At the same time, such as Figure 3 and Figure 9 As shown, multiple removable brackets 400 may be provided, and electrical and electronic components 20 may be fixed to any one of the multiple removable brackets 400, and the multiple removable brackets 400 are arranged along the length direction of the first sub-frame 310 to be fixed to the first sub-frame.

[0070] As described above, electrical and electronic components 20 are fixed to one of the removable brackets 400. When a specific electrical and electronic component 20 is being repaired with the removable bracket 400 fixed to the sub-bracket 300, the corresponding removable bracket 400 to which the specific electrical and electronic component 20 is fixed is separated from the sub-bracket 300 to allow for maintenance, thereby improving manufacturability.

[0071] As described above, when servicing electrical and electronic components 20, the removable bracket 400 can be detached separately to the lower side, making it highly maintainable and easy to install.

[0072] As described above, since the main bracket 200 and the sub-bracket 300 are positioned on the upper and lower sides, the high-voltage battery 10 and the electrical and electronic components 20 are combined in a two-stage and modular manner. When a specific electrical and electronic component 20 is being repaired, the corresponding removable bracket 400 to which the specific electrical and electronic component 20 is fixed is separated from the sub-bracket 300 to allow for maintenance, thereby improving manufacturability due to the improved ease of attachment and removal of the electrical and electronic components 20.

[0073] According to the high-voltage battery bracket for vehicles constructed with the above structure, the high-voltage battery and electrical and electronic components are modularized and integrated into the vehicle frame in two stages, so that the installation space can be reduced and the manufacturability is improved due to the ease of attachment and disassembly of the electrical and electronic components.

[0074] Although preferred embodiments of the present disclosure have been described for illustrative purposes, those skilled in the art will understand that various modifications, additions, and substitutions may be made without departing from the scope and spirit of the disclosure as disclosed in the appended claims.

[0075] Although specific embodiments of the present disclosure have been described in detail, it will be apparent to those skilled in the art that various modifications and substitutions may be made without departing from the technical spirit and scope of the present disclosure, and that such modifications and substitutions fall within the scope of the appended claims.
