[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following is a reference appendix. Figure 1-6 Description of a heat insulation component 100 for a battery pack according to an embodiment of the present invention.

[0027] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 According to an embodiment of the present invention, a heat insulation component 100 for a battery pack is adapted to be disposed at the front end of the battery pack 200 (e.g., ...). Figure 1 The front end of the battery pack 200 shown), the heat insulation assembly 100 includes: a body 10, the body 10 extending along the left-right direction (e.g., the front end of the battery pack 200), and the heat insulation assembly 100 includes: a body 10, the body 10 extending along the left-right direction (e.g., the front end of the battery pack 200). Figure 4 Extending in the left-right direction as shown, and the upper end of the body 10 (as shown) Figure 4 The upper end of the body 10 shown is adapted to connect to the vehicle floor to seal the gap between the battery pack 200 and the vehicle floor.

[0028] For example, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the battery pack 200 is located on the lower side of the vehicle floor, the heat insulation component 100 is located at the front end of the battery pack 200, the body 10 extends in the left and right direction, and the upper end of the body 10 extends upward to the vehicle floor.

[0029] It should be explained that when the vehicle is running, the exhaust pipe will generate hot air, which will be transferred from the gap between the battery pack 200 and the vehicle floor to the upper surface of the battery pack 200. Therefore, a heat insulation component 100 is required to isolate the hot air.

[0030] The present invention discloses a heat insulation component 100 for a battery pack, comprising a body 10, the upper end of which is connected to the vehicle floor to seal the gap between the battery pack 200 and the vehicle floor. This prevents hot air from being transferred to the upper surface of the battery pack 200, thereby reducing the heat radiation of hot air to the battery pack 200. Consequently, the temperature of the battery pack 200 can be stabilized within a suitable operating range, resulting in more stable battery output voltage and current, effectively improving the efficiency of the battery pack 200. At the same time, it can reduce the temperature gradient inside the battery pack 200, making the expansion and contraction of various parts inside the battery pack 200 more uniform, thereby reducing the thermal stress caused by temperature changes in the battery pack 200.

[0031] Furthermore, the stable ambient temperature of the battery pack 200 can reduce problems such as electrode material aging and electrolyte decomposition, thereby slowing down the aging of the battery pack 200, extending its service life, reducing the capacity decay of the battery pack 200, extending its maintenance cycle, and thus reducing operating costs.

[0032] According to an embodiment of the present invention, a heat insulation component 100 for a battery pack is provided with a body 10, the upper end of which is connected to the vehicle floor to seal the gap between the battery pack 200 and the vehicle floor. This reduces the heat radiation of hot air to the battery pack 200, reduces the thermal stress of the battery pack 200 caused by temperature changes, and also improves the service life of the battery pack 200.

[0033] According to some embodiments of this utility model, refer to Figure 3 and Figure 4 The heat insulation assembly 100 for the battery pack includes: a first seal 20, the first seal 20 being disposed on the upper side of the body 10 (e.g., Figure 3 The upper side of the body 10 shown), and the first seal 20 extends in the left-right direction, the first seal 20 being adapted to seal between the upper surface of the body 10 and the vehicle floor.

[0034] In this way, the main body 10 seals the gap between the battery pack 200 and the vehicle floor through the first sealing element 20. Compared with the form in which the main body 10 is directly connected to the vehicle floor, the connection difficulty between the main body 10 and the vehicle floor can be reduced. At the same time, the sealing element can be made of a reasonable material according to actual needs, so as to ensure the sealing performance and effectively prevent hot air from being transferred to the upper surface of the battery pack 200.

[0035] For example, such as Figure 3 and Figure 4 As shown, the first seal 20 is disposed on the upper side of the body 10, the first seal 20 extends in the left and right direction, and the upper surface of the first seal 20 is connected to the vehicle floor.

[0036] According to some optional embodiments of the present invention, refer to Figure 3 and Figure 4 The upper end of the main body 10 is provided with a top-open mounting groove 11, and the mounting groove 11 is located in the left-right direction (e.g., Figure 4 Extending in the left-right direction (as shown), the first sealing element 20 is disposed within the mounting groove 11. Thus, the mounting groove 11 provides an installation position for the first sealing element 20, thereby facilitating its installation. At the same time, the sidewall of the mounting groove 11 can limit the first sealing element 20, thereby effectively preventing the first sealing element 20 from moving relative to the body 10.

[0037] For example, such as Figure 3 and Figure 4 As shown, the mounting groove 11 is located at the upper end of the body 10, and extends in the left-right direction. The left and right sides and the top of the mounting groove 11 are open, and the first sealing member 20 is located inside the mounting groove 11. Furthermore, the thickness of the first sealing member 20 in the front-back direction is 20mm-30mm, and the front and back sides of the first sealing member 20 abut against the front and back edges of the mounting groove 11, thereby ensuring that the first sealing member 20 can be stably installed in the mounting groove 11.

[0038] According to some optional embodiments of the present invention, refer to Figure 4 and Figure 6 The first seal 20 includes the following in the left and right directions (e.g., Figure 6 The first sealing section 21, the second sealing section 22, and the third sealing section 23, which are sequentially connected in the left-right direction (as shown), are in the up-down direction (as shown) Figure 6 In the vertical direction shown, the height of the second sealing section 22 is greater than the height of the first sealing section 21 and the third sealing section 23.

[0039] In this way, the first sealing member 20 can be adapted to the shape of the vehicle chassis, thereby effectively sealing the gap between the battery pack 200 and the vehicle floor. At the same time, the height of the second sealing section 22 is greater than the height of the first sealing section 21 and the third sealing section 23, so the second sealing section 22 can be limited at its position, thereby preventing the first sealing member 20 from shaking in the front and back directions.

[0040] For example, such as Figure 4 and Figure 6 As shown, the first sealing section 21, the second sealing section 22 and the third sealing section 23 are connected sequentially in the left-right direction. The height of the second sealing section 22 is higher than the height of the first sealing section 21 and the third sealing section 23. The first sealing section 21 and the third sealing section 23 are at the same height in the up-down direction.

[0041] According to some optional embodiments of the present invention, refer to Figure 4and Figure 6 Both the first sealing section 21 and the third sealing section 23 are detachably connected to the second sealing section 22. Therefore, the separate design of the first sealing element 20 reduces the processing difficulty and improves processing efficiency. Furthermore, the simple connection between the first sealing section 21, the second sealing section 22, and the third sealing section 23 facilitates the assembly of the first sealing element 20. In addition, from... Figure 6 As can be seen, the first sealing section 21 and the third sealing section 23 are elongated structures, which can be used to process leftover materials, thereby improving material utilization.

[0042] For example, such as Figure 4 and Figure 6 As shown, the left end of the first sealing section 21 is inserted and connected to the right end of the second sealing section 22, and the right end of the third sealing section 23 is inserted and connected to the left end of the second sealing section 22.

[0043] According to some optional embodiments of the present invention, refer to Figure 4 and Figure 5 The front and rear sides of the mounting slot 11 (such as Figure 5 The mounting groove 11 shown has upwardly extending limiting plates 12 on both the front and rear sides. The limiting plates 12 are located on the body 10 in the left and right directions (e.g., Figure 5 The second sealing section 22 is located in the middle position on the left and right sides (as shown), between the two limiting plates 12.

[0044] In this way, the limiting plate 12 can limit the first seal 20 in the front-back direction, thereby effectively preventing the first seal 20 from moving relative to the body 10 in the front-back direction, and thus effectively sealing the gap between the battery pack 200 and the vehicle floor.

[0045] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The heat insulation component 100 for the battery pack includes: a limiting member 30, which is fixed in the mounting groove 11; a first sealing member 20 having a limiting groove, and the limiting member 30 fitting into the limiting groove. Thus, the limiting member 30, in cooperation with the limiting groove, can limit the first sealing member 20, effectively preventing it from moving within the mounting groove 11, thereby ensuring the sealing effect of the first sealing member 20.

[0046] For example, such as Figure 4 and Figure 5 As shown, the limiting member 30 is formed into an inverted V-shaped structure with the opening facing downward. The lower end of the limiting member 30 is fixed to the bottom wall of the mounting groove 11, and the upper end of the limiting member 30 extends upward. The lower end of the first sealing member 20 is provided with a limiting groove that penetrates the first sealing member 20 in the front-back direction. The limiting member 30 is fitted into the limiting groove to restrict the left and right movement of the first sealing member 20.

[0047] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The main body 10 includes a main board 101 and a mating plate 102. The main board 101 is vertically arranged and extends horizontally, and is adapted to be fixed to the front end of the battery pack 200. The mating plate 102 is located on top of the main board 101 and is positioned relative to the main board 101 in the front-rear direction (e.g., ...). Figure 4 The components are arranged and connected in the front-to-back direction (as shown), and the main board 101 and the mating board 102 cooperate to define the mounting slot 11.

[0048] In this way, the separate body 10 can reduce the processing difficulty of the body 10, thereby improving the processing efficiency of the body 10. At the same time, the motherboard 101 can effectively isolate the hot air from the exhaust pipe in the battery pack 200, thereby preventing the hot air from the exhaust pipe from being transferred to the front surface of the battery pack 200. Furthermore, the motherboard 101 and the mating plate 102 can directly define the mounting slot 11 without the need for additional processing of the mounting slot 11, thereby saving processing steps.

[0049] For example, such as Figure 4 and Figure 5 As shown, the motherboard 101 extends vertically in the up-down direction and is fixed to the front side of the battery pack 200. The mating plate 102 is mated to the top of the motherboard 101 and is located on the rear side of the motherboard 101. The mating plate 102 and the motherboard 101 cooperate to define the mounting slot 11.

[0050] Furthermore, such as Figure 4 and Figure 5 As shown, a limiting plate 12 is provided on the main board 101, and a limiting plate 12 is provided on the mating plate 102. The two limiting plates 12 are arranged at intervals along the front-back direction.

[0051] Furthermore, such as Figure 4 and Figure 5 As shown, the upper end of the main board 101 is provided with a first flange 1011, which extends forward. The lower end of the mating board 102 is provided with a second flange 1021, which extends forward and is located on the upper side of the first flange 1011. The second flange 1021 is welded to the first flange 1011, thereby forming a limiting groove that is open on the left and right sides and the top.

[0052] According to some optional embodiments of the present invention, refer to Figure 4 and Figure 5The main board 101 and the mating board 102 are made of steel or aluminum. This ensures that both the main board 101 and the mating board 102 have good heat insulation, thus preventing the battery pack 200 from being affected by heat radiation. At the same time, it ensures the structural strength of the main board 101 and the mating board 102, effectively preventing damage to them.

[0053] Preferably, the body 10 can be a double-sided aluminized steel plate, an embossed aluminum plate, or a flat aluminum plate, and the thickness of the body 10 can be 1mm-2mm, thereby ensuring the heat insulation effect of the body 10.

[0054] According to some embodiments of this utility model, refer to Figure 5 and Figure 6 The first sealing element 20 is made of silicone. Therefore, the silicone element has a certain deformation modulus. When the main body 10 is connected to the vehicle floor, the first sealing element 20 is compressed and deformed, thus effectively sealing the gap between the battery pack 200 and the vehicle floor. At the same time, this structure is simple, inexpensive, and easy to mass-produce.

[0055] Preferably, the first sealing element 20 is foamed silicone rubber. Foamed silicone rubber has excellent high temperature resistance, low compression performance and excellent chemical stability, and can achieve efficient heat insulation with an ultra-thin thickness. At the same time, the first sealing element 20 is interference-fitted with the vehicle floor. At this time, the first sealing element 20 is compressed, and hot air cannot flow over the upper surface of the battery pack 200 during vehicle operation, which effectively improves the thermal radiation effect of hot air on the upper surface of the battery pack 200.

[0056] Furthermore, the compression of the foamed silicone rubber in the vertical direction is 15%-20%, which can effectively ensure that the first seal 20 can seal the gap between the battery pack 200 and the vehicle floor.

[0057] According to some embodiments of this utility model, refer to Figure 3 , Figure 4 and Figure 5 The body 10 is provided with a plurality of through holes 13 arranged at intervals, that is, the body 10 is provided with two, three, four or more through holes 13 arranged at intervals. The heat insulation assembly 100 also includes: a second sealing member 40, the second sealing member 40 being connected to the body 10 and disposed on the rear side of the body 10 (e.g., Figure 4 (The rear side of the main body 10 shown) The second sealing member 40 is provided with a plurality of perforations 41. That is, the second sealing member 40 is provided with two, three or four or more perforations 41 arranged at intervals. The plurality of perforations 41 correspond one-to-one with the plurality of through holes 13. The perforations 41 and the corresponding through holes 13 are directly opposite each other and connected.

[0058] In this way, the perforation 41 and the through hole 13 are directly opposite each other, which makes it convenient for the components of the battery pack 200 to pass through the perforation 41 and the through hole 13 and connect to the external structure. At the same time, the second seal 40 can seal the through hole 13 on the periphery, thereby preventing hot air from being transmitted to the front end of the battery pack 200 through the periphery of the through hole 13.

[0059] According to some optional embodiments of the present invention, refer to Figure 3 , Figure 4 and Figure 5 The second seal 40 is formed along the front-rear direction (e.g. Figure 4 The heat insulation hole 42 (shown in the front-back direction) penetrates the second seal 40, and the body 10 is located on the front side of the second seal 40 and covers the heat insulation hole 42. Thus, air is stored in the heat insulation hole 42. Since air has a low thermal conductivity, it can further prevent hot air from the exhaust pipe from being transferred to the battery pack 200 through the body 10, thereby further reducing the impact of hot air on the battery pack 200.

[0060] For example, such as Figure 3 , Figure 4 and Figure 5 As shown, the heat insulation hole 42 is located on the left side of the second seal 40 and extends through the second seal 40 in the front-rear direction. The body 10 covers the front side of the heat insulation hole 42, and the front end face of the battery pack 200 covers the rear side of the heat insulation hole 42, thereby forming a closed heat insulation cavity between the battery pack 200 and the body 10.

[0061] According to some embodiments of this utility model, refer to Figure 3 , Figure 4 and Figure 5 A portion of the multiple through holes 13 are formed as fastening holes 131 suitable for fasteners 300 to pass through. Thus, fasteners 300 can pass through fastening holes 131 to fix the body 10 to the battery pack 200, thereby facilitating the connection between the body 10 and the battery pack 200. At the same time, the second seal 40 can circumferentially seal the fastening port, thereby preventing hot air from being transmitted to the battery pack 200 through the fastening holes 131.

[0062] Furthermore, referring to Figure 3 , Figure 4 and Figure 5 A portion of the multiple through holes 13 is formed as a clearance hole 132 suitable for the insertion of the connector 210. Thus, the connector 210 can pass through the clearance hole 132 to electrically connect the battery pack 200 to an external structure, thereby facilitating the connection between the battery pack 200 and the external structure. At the same time, the second seal 40 can circumferentially seal the clearance hole, thereby preventing hot air from being transmitted to the battery pack 200 through the clearance hole 132.

[0063] Furthermore, the fastener 300 can be a rivet nut, which can effectively increase the fixing strength and vibration mode of the heat insulation component 100 and the battery pack 200.

[0064] Furthermore, such as Figure 5 and Figure 6 As shown, the second sealing element 40 is made of silicone. Therefore, the silicone material has a certain deformation modulus. When the body 10 is connected to the battery pack 200, the second sealing element 40 is subjected to compression deformation, thereby effectively sealing the gap between the battery pack 200 and the body 10. At the same time, this structure is simple, low-cost, and easy to mass-produce.

[0065] Preferably, the second seal 40 is made of foamed silicone rubber, which has excellent high temperature resistance, low compression performance and excellent chemical stability, and can achieve efficient heat insulation with ultra-thin thickness.

[0066] Furthermore, referring to Figure 3 , Figure 4 and Figure 5 The body 10 is provided with a leakage hole 14, which is used to drain the liquid flowing to the upper end of the heat insulation component 100 out of the heat insulation component 100, thereby effectively preventing liquid from being sucked into the first seal 20 and the second seal 40, and thus protecting the first seal 20 and the second seal 40.

[0067] According to a second aspect embodiment of the present invention, a battery device 1000 is described, with reference to... Figure 1 , Figure 2 and Figure 3 It includes: a battery pack 200 and a heat insulation component 100 for the battery pack according to the first aspect of this embodiment, wherein the heat insulation component 100 is fixed to the front side of the battery pack 200.

[0069] The vehicle according to the third aspect embodiment of the present utility model, referring to Figure 1 , Figure 2 and Figure 3 The system includes: a vehicle body and a battery device 1000 according to the second aspect of this embodiment. The vehicle body includes a vehicle floor and an exhaust pipe. The battery device 1000 is located on the underside of the vehicle floor (not shown in the figure) and arranged behind the exhaust pipe. A gap channel is formed between the battery pack 200 and the vehicle floor. The upper end of the body 10 (e.g., Figure 3 The upper end of the body 10 shown is connected to the vehicle floor and blocks the front opening of the gap channel.

[0070] For example, such as Figure 1 , Figure 2 and Figure 3 As shown, the battery device 1000 is located on the lower side of the vehicle floor. A gap channel is formed between the upper surface of the battery device 1000 and the vehicle floor. The upper end of the main body 10 is press-fitted with the first plate of the vehicle through the first sealing member 20 to seal the front opening of the gap channel.
