[0028] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0029] Reference below Figure 1-Figure 4 A protection assembly 1 of a box body 40 according to an embodiment of the present utility model is described. The protection assembly 1 of the box body 40 can be constructed into a box body 40 structure of a battery pack.

[0030] like Figure 1 As shown, the protection assembly 1 according to the embodiment of the utility model includes: a protection plate 10 and a heat preservation member 20. The protection plate 10 is the main part of the protection assembly 1, which can be mainly used to resist obstacles that are scratched under the vehicle during driving, thereby reducing damage, and the heat preservation member 20 can mainly play a role of heat preservation. It is used to improve the heat preservation effect of the battery pack, reduce external impact and enhance the anti-collision ability.

[0031] like Figure 1 and Figure 4 As shown, a cavity 105 is formed in the protective plate 10, and the thermal insulation component 20 is arranged in the cavity 105, and when the protective plate 10 is damaged, the thermal insulation component 20 is suitable for contacting with the air and solidifying. The thermal insulation component 20 is arranged in the cavity 105, so that the thermal insulation component 20 can improve the thermal insulation effect of the battery pack, block the heat at the bottom of the battery pack from diffusing outward, and reduce the external impact effect, thereby achieving the effect of thermal insulation and shock absorption. In addition, it should be noted that the thermal insulation component 20 is non-solid in the sealed cavity 105. When the protective plate 10 is damaged due to external impact, the built-in thermal insulation component 20 can quickly solidify when in contact with the air to prevent water from entering the battery pack.

[0032] Thus, a cavity 105 is formed in the protective component 10, and a thermal insulation component 20 is arranged in the cavity 105, which can prevent the heat from the bottom of the battery pack from diffusing outward to achieve the effect of heat preservation and shock reduction. Secondly, the carrying capacity of the battery pack is enhanced and the risk of impact of complex external road conditions on the internal battery cells or modules of the battery pack is resisted. When the bottom of the tray is impacted by external force, the internal battery cells or modules of the tray are protected to a certain extent by reducing the impact force. In addition, the thermal insulation component 20 is non-solid in the sealed cavity 105. When the protective plate 10 is damaged by external impact, the built-in thermal insulation component 20 can quickly solidify when in contact with the air to prevent water from entering the battery pack.

[0033] Specifically, Figure 3 and Figure 4 As shown, when the thermal insulation component 20 is arranged in the cavity 105, the thermal insulation component 20 is constructed as a colloid structure. The thermal insulation component 20 is constructed as a colloid structure, so that the thermal insulation component 20 can play a bonding role, and then the thermal insulation component 20 is arranged in the cavity 105, so that the connection between the guard plates 10 can be more stable and firm, thereby making the structure of the box body 40 more stable. In addition, when the bottom of the tray is impacted by external force, it can play a certain protective role in reducing the impact force on the battery cells or modules inside the tray, thereby achieving a shock-absorbing effect on the entire vehicle. It should be noted that the structure of the thermal insulation component 20 can be other non-solid structures other than the colloid structure.

[0034] Among them, Figure 3 and Figure 4 As shown, the thermal insulation component 20 includes: a first colloid and a second colloid, and the first colloid and the second colloid are mixed and arranged in the cavity 105. In other words, the thermal insulation component 20 can be divided into two different colloids for mixing, so that the thermal insulation component 20 can be injected into the protective plate 10 and sealed in the case of isolating oxygen, forming a non-solid state with thermal insulation effect. When the protective plate 10 is damaged by external impact, the built-in thermal insulation component 20 can quickly solidify when in contact with the air, seal the damaged position, and prevent the battery pack from getting water, thereby effectively protecting the battery pack. Of course, the thermal insulation component 20 can also be a mixture of multiple other colloids.

[0035] In addition, if Figure 1 As shown, the guard plate 10 includes: a first guard plate 101 and a second guard plate 102, the first guard plate 101 is connected to the second guard plate 102, and a cavity 105 is defined between the first guard plate 101 and the second guard plate 102. The first guard plate 101 and the second guard plate 102 are connected so that the guard plate 10 forms a whole, which is convenient for the installation and setting of the protective component 1, and a cavity 105 can be defined between the first guard plate 101 and the second guard plate 102. Specifically, a hole for injecting the thermal insulation component 20 can be set on the first guard plate 101, and then the thermal insulation component 20 can be injected into the guard plate 10 and sealed in the case of isolating oxygen, so as to form a non-solid state with thermal insulation effect. Among them, brazing can be used between the first guard plate 101 and the second guard plate 102, and at this time, the weld is flat, the size is precise, and the structure is simple and generous.

[0036] Of course, if Figure 2As shown, the first guard plate 101 includes: a main body 103 and a partition portion 104. In the first direction, the partition portion 104 is arranged at intervals on the main body 103. Specifically, the main body 103 is the main component of the first guard plate 101, and the partition portion 104 can mainly play a role of partition. In the first direction, the partition portion 104 is arranged at intervals on the main body 103. It should be noted that the first direction is perpendicular to the driving direction, and a plurality of transverse partition portions 104 are arranged at intervals on the main body 103. In this way, the plurality of transverse partition portions 104 can form a countermeasure against obstacles that are scratched under the vehicle during driving, reduce the damage to the battery pack, and at the same time improve the battery pack mode to resist the risk of failure of the battery pack in the height direction under various road conditions.

[0037] Furthermore, if Figure 2 As shown, the distance between two adjacent partition parts 104 is a, and the value range of a is: 4mm≤a≤18mm. It should be noted that the spacing between two adjacent partition parts 104 needs to meet a certain range. Specifically, the spacing between two adjacent partition parts 104 cannot be too small, that is, less than 4 mm. In this way, under the premise that the partition parts 104 can play a partitioning role, the partition parts 104 will be too densely arranged, which is not conducive to the arrangement of the partition parts 104 and will increase the cost. At the same time, the spacing between two adjacent partition parts 104 cannot be too large, that is, greater than 18 mm. In this way, the spacing between two adjacent partition parts 104 is too large, which will affect the partition effect of the partition part 104 on the first guard plate 101 and may cause damage to the first guard plate 101, affecting the confrontation with obstacles that scratch the bottom of the vehicle during driving, thereby causing damage to the battery pack, and is not conducive to improving the battery pack mode, and is not conducive to resisting the risk of battery pack height direction vibration failure under various road conditions, affecting the protection effect of the protective component 1 on the battery pack, and further affecting the safety, reliability and stability of the vehicle during driving.

[0038] In addition, Figure 2 As shown, the partition part 104 is welded to the main body 103, or the partition part 104 is integrally formed on the main body 103. That is to say, the partition part 104 and the main body 103 can be welded by a special welding machine, which can make the weld smooth, the size accurate, the structure simple and generous, and can ensure the firmness and reliability of the connection between the partition part 104 and the main body 103. Alternatively, the partition part 104 and the main body 103 are made into an integrated structure, in which case the first guard plate 101 is an integrated structure, which is more stable and firm, and is easy to install and set. At the same time, only one processing mold is needed, which is easy to produce and manufacture.

[0039] like Figure 1As shown, the box body 40 according to the embodiment of the utility model comprises: a main box body 30 and the protective component 1 described in the above embodiment, and the protective component 1 is connected to the main box body 30. The guard plate 10 and the main box body 30 are connected by bolts or rivets, which are easy to install and disassemble, have strong practicality, and reliable structure. When the second guard plate 102 is bumped or deformed by force, the damaged second guard plate 102 can be disassembled and replaced, which is convenient to disassemble and replace, thereby saving maintenance costs.
