[0026] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0027] In the present disclosure, unless otherwise stated, the first direction and the second direction are as follows: Figure 1 As shown, the terms "first", "second", etc. are only used to distinguish the descriptions and should not be understood as indicating or implying relative importance.

[0028] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, a detachable connection, or an integral connection. They may be directly connected or indirectly connected through an intermediate medium, or they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0029] In the prior art, commercial vehicle battery packs are typically mounted on the vehicle frame, typically arranged in two or more layers. However, the upper battery packs are susceptible to vibration, resulting in lower vibration modes for the battery pack and battery holder. This can cause the battery holder to break, posing a risk of the battery pack falling. Furthermore, excessive vibration can disconnect the battery pack's low-voltage wiring harness, disrupting communications and impacting the entire vehicle system.

[0030] For this reason, Figure 1 As shown, one aspect of the present disclosure provides a reinforcement device including a first reinforcement member 1 and a second reinforcement member 2 .

[0031] The first reinforcement 1 extends along a first direction. The first reinforcement 1 has a first connecting surface and a second connecting surface. A first connecting portion 11 is provided on the first connecting surface. The first connecting portion 11 is used to connect to the first component to be reinforced.

[0032] The second reinforcement member 2 extends along the second direction. The second reinforcement member 2 has a third connecting surface and a fourth connecting surface. The third connecting surface is provided with a second connecting portion 21 . The second connecting portion 21 is used to connect to the second component to be reinforced.

[0033] The second connecting surface is connected to the fourth connecting surface, and the first direction and the second direction are arranged at an angle.

[0034] In the above technical solution, the first reinforcement 1 and the second reinforcement 2 are connected to each other, and the first reinforcement 1 and the second reinforcement 2 are set at an angle, which can facilitate the connection between the first reinforcement 1 and the first component to be reinforced, and the connection between the second reinforcement 2 and the second component to be reinforced, thereby producing a connection reinforcement effect. The first component to be reinforced can be a column 3, and the second component to be reinforced can be a tray 4, and the tray 4 is used to place the battery pack. In this way, the integrity of the battery pack, the tray 4 and the column 3 can be improved, the vibration modal value of the constructed battery bracket can be improved, and the risk of cracking of the battery bracket can be greatly reduced. At the same time, the risk of disconnection of the low-voltage wiring harness can also be reduced.

[0035] Optionally, in one embodiment of the present disclosure, the first direction and the second direction are perpendicularly arranged, the first direction is parallel to the extension direction of the column 3, and the second direction is parallel to the extension direction of the tray 4. This arrangement can better connect with the column 3 and the tray 4, generate lateral tension, and improve the integrity between the column 3 and the tray 4.

[0036] The first reinforcement 1 and the column 3 extend in the same direction, that is, they both extend in the first direction, allowing the first reinforcement 1 to fit the surface of the column 3, increasing the connection area and strengthening the connection. Similarly, the second reinforcement 2 and the tray 4 extend in the same direction, that is, they both extend in the second direction, allowing the second reinforcement 2 to fit the surface of the tray 4, increasing the connection area and strengthening the connection.

[0037] Optionally, in another embodiment of the present disclosure, the first direction and the second direction may form an acute angle or an obtuse angle, which may be selected according to actual conditions.

[0038] Optionally, in one embodiment of the present disclosure, in the first direction, the second connecting surface has a first end and a second end, and in the second direction, the fourth connecting surface has a third end and a fourth end, the first end of the second connecting surface is connected to the third end of the second connecting surface, the second end of the second connecting surface is close to the tray 4, and the fourth end of the second connecting surface is away from the column 3. Through such an arrangement, the structural dimensions of the first reinforcement member 1 and the second reinforcement member 2 can be reduced, and at the same time, interference with the second reinforcement member 2 when the first reinforcement member 1 is connected to the column 3 and interference with the first reinforcement member 1 when the second reinforcement member 2 is connected to the tray 4 can be avoided, thereby facilitating assembly.

[0039] At present, there are some side reinforcement structures for battery brackets, which have large structural dimensions, occupy more space, and are also heavy, affecting the layout of the battery pack of the entire vehicle and also having a certain impact on the weight of the entire vehicle. Optionally, in one embodiment of the present disclosure, the first reinforcement 1 includes two first plates 12 and a plurality of first support plates 13, one side of the two first plates 12 is connected to each other, the two first plates 12 are arranged at an angle, and the plurality of first support plates 13 are respectively connected to the two first plates 12, one side of the two first plates 12 is respectively set as the first connecting surface and the second connecting surface, and the first connecting portion 11 is set on one first plate 12. By such a setting, the weight and size of the first reinforcement 1 can be reduced without affecting the spatial layout and the weight of the entire vehicle.

[0040] It can be understood that the end surfaces of the two first plates 12 that are close to each other are connected to each other, so that there is a certain angle between the two first plates 12. After the multiple first support plates 13 are respectively connected to the two first plates 12, the multiple first support plates 13 can provide support and reinforcement for the two first plates 12, thereby ensuring the structural strength of the entire first reinforcement 1.

[0041] The first connecting portion 11 is used to connect to the column 3 , and the first plate 12 provided with the first connecting portion 11 is fitted with the surface of the column 3 to facilitate connection, while the other first plate 12 is used to connect to the second reinforcement 2 .

[0042] Optionally, in one embodiment of the present disclosure, the two first plates 12 are perpendicular to each other, and the plurality of first support plates 13 are disposed perpendicular to the two first plates 12. This arrangement facilitates connection of the two first plates 12 to the second reinforcement 2 and the column 3, respectively. The first support plates 13 are perpendicular to the first plates 12, thereby enhancing support and reinforcement for the first plates 12 and thereby improving the structural strength of the entire first reinforcement 1.

[0043] Optionally, in another embodiment of the present disclosure, the first reinforcement member 1 may be a reinforcement pillar, and the reinforcement pillar is an integral solid structure.

One side of the two second plates 22 is connected to each other, the two second plates 22 are arranged at an angle, and the plurality of second support plates 23 are respectively connected to the two second plates 22. One side of the two second plates 22 is respectively provided as the third connecting surface and the fourth connecting surface, and the second connecting portion 21 is provided on one of the second plates 22. This arrangement can reduce the weight and size of the second reinforcement 2 without affecting the space layout and the weight of the entire vehicle.

[0045] It can be understood that the end faces of the two second plates 22 that are close to each other are connected to each other, so that there is a certain angle between the two second plates 22. After the multiple second support plates 23 are respectively connected to the two second plates 22, the multiple second support plates 23 can provide support and reinforcement for the two second plates 22, thereby ensuring the structural strength of the entire second reinforcement 2.

[0046] The second connecting portion 21 is used to connect to the tray 4 , and the second plate 22 provided with the second connecting portion 21 is fitted with the surface of the tray 4 to facilitate connection, while the other second plate 22 is used to connect to the first reinforcement 1 .

[0047] Optionally, in one embodiment of the present disclosure, the two second plates 22 are perpendicular to each other, and the plurality of second support plates 23 are arranged perpendicular to the two second plates 22. This arrangement facilitates the connection of the two second plates 22 to the first reinforcement member 1 and the tray 4, respectively. The second support plates 23 are perpendicular to the second plates 22, thereby enhancing the support and reinforcement effect on the second plates 22, thereby improving the structural strength of the entire second reinforcement member 2.

[0048] Optionally, in another embodiment of the present disclosure, the second reinforcement member 2 may be a reinforcement pillar, and the reinforcement pillar is an integral solid structure.

[0049] Optionally, in one embodiment of the present disclosure, the first connecting portion 11 and the second connecting portion 21 are both configured as connecting holes, the first connecting portion 11 being connected to the column 3 via bolts, and the second connecting portion 21 being connected to the tray 4 via bolts. This arrangement facilitates the connection of the first reinforcement member 1 to the column 3 and the connection of the second reinforcement member 2 to the tray 4.

[0050] It is understood that the connection hole is a through hole that passes through the first plate 12 and the second plate 22, capable of allowing a bolt to pass through. Corresponding mounting holes can be provided on the column 3 and the tray 4 for connection with the bolt. In some examples, the number of first connecting portions 11 can be two, and the two first connecting portions 11 are arranged in parallel. The number of second connecting portions 21 can be two, and the two second connecting portions 21 are arranged in parallel.

[0052] By providing a reinforcing device, the connection strength between the column 3 and the tray 4 can be strengthened, the stability of the entire battery bracket can be improved, and the vibration effect on the battery pack installed on the tray 4 can be reduced.

[0053] Among them, the pallets 4 located on the upper layer can be equipped with reinforcement devices, while the pallets 4 located on the lower layer, that is, closer to the frame, do not need to be equipped with reinforcement devices. The pallets 4 closer to the frame are less affected by vibration due to the support of the frame. It is understood that the number of reinforcement devices can be coordinated with the number of pallets 4. When there are two pallets 4, the pallets 4 on the lower layer do not need to be equipped with reinforcement devices, while the pallets 4 on the upper layer can be equipped with reinforcement devices. When there are more than two pallets 4, the pallet 4 on the lower layer does not need to be equipped with reinforcement devices, while the other pallets 4 can be equipped with reinforcement devices.

[0054] Each pallet 4 may be provided with four reinforcing devices, and the first reinforcing members 1 of the four reinforcing devices are connected to the four columns 3 respectively.
