[0002] Lithium-ion electric vehicles are lithium-ion battery electric vehicles, which refer to electric vehicles equipped with lithium-ion batteries. Lithium-ion batteries have the characteristics of light weight, large energy storage, high power and no pollution. In recent years, the environmental problems caused by traditional internal combustion engine vehicles and the shortage of oil resources have made people turn their attention to new energy vehicles. Pure electric vehicles have become an important development direction of electric vehicles because they can truly achieve "zero emissions". Lithium-ion batteries have become the ideal power source for the new generation of electric vehicles due to their excellent performance.

[0003] Currently, lithium batteries on new energy vehicles are usually composed of multiple lithium battery blocks assembled in a protective box. However, the internal space is relatively narrow, especially when the lithium battery blocks are installed one by one inside, which makes it difficult for the internal heat to dissipate, which will have a significant impact on the battery life over time.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0029] See also Figure 1-Figure 4 The present application provides a new energy vehicle lithium battery protection structure including a protection component 100 and a heat dissipation component 200.

[0030] See also Figure 1 ,2 and 3, the protective assembly 100 includes a protective shell 110, a partition 120, a support plate 140 and a lithium battery block 160, the partition 120 is arranged in the protective shell 110, the support plate 140 is arranged in the protective shell 110, the lithium battery block 160 is arranged in the protective shell 110 and connected to the support plate 140, and the protective shell 110 is installed at the bottom of the new energy vehicle in conjunction with the cover plate.

[0031] Among them, a support pad 121 is arranged on the side of the partition 120, and the support pad 121 contacts the lithium battery block 160. By setting the support pad 121, it is used to contact and support the lithium battery block 160 and reduce the contact area with the lithium battery block 160 to ensure the heat dissipation area, while ensuring the stability of the installation and improving the protection.

[0032] In a specific implementation scheme, a support pad 121 is also provided on the inner wall of the protective shell 110. The support pad 121 is T-shaped and arranged horizontally. By providing the T-shaped support pad 121 and arranging it horizontally, the occupied space can be reduced as much as possible and a smooth channel can be provided for gas flow.

[0033] In this embodiment, an extension block 161 is provided at the end of the lithium battery block 160, and a fixing bolt 162 is provided through the extension block 161 and is threadedly connected to the support plate 140. By providing the extension block 161 and the fixing bolt 162, the fixing bolt 162 can be passed through the fixing bolt 162 to be installed on the support plate 140 and the protective shell 110, so that the lithium battery block 160 can be stably installed inside.

[0034] Specifically, the partition 120 and the support plate 140 do not contact, the partition 120 and the protective shell 110 do not contact, and the support plate 140 is provided with a plurality of threading holes. By providing an independently vertically arranged partition 120, the contact between the partition 120 and the support plate 140 and resulting in blocked sealed air circulation is avoided. The threading holes can be used for threading as well as for air flow.

[0035] See also Figure 1 , 2 4, the heat dissipation assembly 200 includes a dustproof net 210, a sealing baffle 230, a heat dissipation fan 240 and a driving member 250. A heat dissipation port 111 is opened at the end of the protective shell 110. The dustproof net 210 is arranged in the heat dissipation port 111. The sealing baffle 230 is slidably arranged in the heat dissipation port 111. The heat dissipation fan 240 is arranged in the protective shell 110. The driving member 250 is arranged at the end of the protective shell 110 and is connected to the sealing baffle 230.

[0036] Among them, the driving member 250 includes a bidirectional screw 251, a motor 252 and a moving block 253. The bidirectional screw 251 is rotatably arranged at the end of the protective shell 110. The motor 252 is installed at the end of the protective shell 110 and is transmission-connected to the bidirectional screw 251. The moving block 253 is threadedly sleeved on the surface of the bidirectional screw 251 and is connected to the sealing baffle 230. By setting the bidirectional screw 251, the motor 252 and the moving block 253, the motor 252 is started, the motor 252 drives the bidirectional screw 251 to rotate, the bidirectional screw 251 drives the moving block 253 to move, and the moving block 253 drives the sealing baffle 230 to move and adjust the position.

[0037] In a specific implementation scheme, the movable block 253 and the sealing baffle 230 are connected through an L-shaped block 231, the sealing baffle 230 fits the inner wall of the heat dissipation port 111, and the length of the sealing baffle 230 is half of the length of the heat dissipation port 111. By setting the length of the sealing baffle 230 to half of the length of the heat dissipation port 111, the sealing baffle 230 blocks the dustproof net 210 in humid weather to prevent humid air from entering. When heat dissipation is needed, the sealing baffle 230 is moved to the other end of the heat dissipation port 111, and the air is ventilated and dissipated through the dustproof net 210.

[0038] The working principle of the lithium battery protection structure of the new energy vehicle is as follows: during use, the cooling fan 240 is started, and the cooling fan 240 drives the air flow. The cooling fan 240 enters from the heat dissipation port 111 and the dustproof net 210 at one end of the protective shell 110, passes through each lithium battery block 160 in the protective shell 110, and then flows out from the heat dissipation port 111 and the dustproof net 210 at the other end of the protective shell 110, thereby taking away the internal heat, effectively dissipating the heat, and preventing the lithium battery block 160 from being affected by high temperature in terms of service life and normal operation. At the same time, the partition 120 and the T-shaped support pad 121 provide heat dissipation for the lithium battery. The support and protection of the battery block 160 not only separates the lithium battery block 160 to support installation, but also can minimize the occupied space and provide a smooth channel for gas flow. Furthermore, in humid weather, the motor 252 is started, the motor 252 drives the bidirectional screw 251 to rotate, the bidirectional screw 251 drives the moving block 253 to move, and the moving block 253 drives the sealing baffle 230 to move and fit to block the dustproof net 210, and temporarily does not dissipate heat to prevent humid air from entering the interior. On the contrary, the sealing baffle 230 moves to the other end of the heat dissipation port 111, and the air is ventilated and dissipated through the dustproof net 210.

[0039] It should be noted that the specific model specifications of the lithium battery block 160 and the motor 252 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0040] The power supply and principle of the lithium battery block 160 and the motor 252 are clear to those skilled in the art and will not be described in detail here.

[0041] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
