Description

Technical Field

[0001] The present invention belongs to the technical field of battery casings, and in particular relates to a battery casing structure for new energy vehicles. Background Art

[0002] The battery housing for new energy vehicles is a key component of the electric vehicle power battery system. It is responsible for protecting the battery module from external damage, providing stable mechanical support for the battery pack, ensuring that the battery operates within the normal temperature range, and maintaining the waterproof and airtightness of the battery pack. In terms of material selection, battery housings show diversity, including aluminum housings, which are easy to process, corrosion-resistant, and have good heat transfer and electrical conductivity; steel housings, which are favored for their high strength, formability and cost-effectiveness; and composite materials, such as glass fiber, SMC sheet materials or carbon fiber reinforced composite materials, which are lightweight, high strength, corrosion resistance, shock absorption, impact resistance, insulation and flame retardant properties. Excellent features have attracted more and more attention in the pursuit of energy-saving, environmental protection and lightweight automobile manufacturing trends.

[0003] In the Chinese patent with the publication number CN110313082A, a battery housing for electric motor-driven vehicles is mentioned, which is the result of ingeniously combining the provision of an energy dissipation path through deformation with the provision of force bearing in the housing component through a bracket element. The energy that can be absorbed without damage to the battery module and the cooling plate is significantly increased without significantly increasing the weight due to particularly stable or expensive components.

[0004] Although the battery housing in the above-mentioned reference document can protect the internal components from the bottom, most of the existing battery housings for new energy vehicles adopt a single-function structural design, such as focusing on buffering and shock absorption to improve impact resistance;

[0005] When faced with complex and ever-changing road conditions and emergencies, in particular, when a traditional battery shell is subjected to a strong external impact, although it can absorb some energy through the built-in buffer material, it is often unable to ensure that the sealing of the shell is not affected at the same time, resulting in water, dust and other foreign substances possibly invading the battery, causing safety hazards such as short circuits and corrosion. In addition, even if the shell has a certain degree of waterproof and dustproof capabilities, when it is subjected to a severe impact, the sealing structure may fail due to deformation and cannot continue to protect the safety of the battery pack.

The reinforcing grid can be inserted into the two sides of the upper detour plate through the buffer plug blocks, thereby increasing the buffering property of the shell at the side where there is no protection of the horizontal support plate, so that the impact force will be absorbed in part by the upper curved plate, the lower curved plate, the concave-convex plate, the upper detour plate, the miter plate and the lower detour plate in sequence.

[0020] 3. The present invention sets a linkage mechanism. When the shell is impacted and deformed at a position where there is no cross support plate reinforcement, and part of the impact force is buffered by the buffer mechanism, the other part of the impact force will be transmitted through the inside of the cross support plate to make the push block push the slider to move in the opposite direction to the source of the impact force, so that the internal clamping block can passively engage the ratchet bar, and then after the impact ends, the top block will always be in a state of squeezing the concave sealing ring and the convex sealing ring to increase the sealing performance.

[0047] Reference Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 In a further embodiment, the concave-convex plates 98 are symmetrically distributed on both sides of the miter plate 97, the miter plate 97 fits the inner side of the concave-convex plate 98, and the side of the receiving plate 91 away from the concave-convex plate 98 is fixedly connected to two symmetrical docking plates 92, the horizontal support plate 81 is provided with a through groove 82, and the top of the horizontal support plate 81 is provided with a rectangular groove 83, and the lower part of the push block 88 is slidably connected to the inside of the rectangular groove 83.

[0048] In this embodiment, the upper curved plate 93, the upper detour plate 94, the lower curved plate 95, the lower detour plate 96, the miter plate 97 and the concave-convex plate 98 can be divided into three parts of left, middle and right to buffer the impact force. The left and right parts are the upper curved plate 93, the concave-convex plate 98 and the lower curved plate 95, and the middle part is the upper detour plate 94, the miter plate 97 and the lower detour plate 96 and the buffer plug 64 inserted on both sides of the upper detour plate 94, so as to buffer the impact force in a multi-stage linkage manner when the side surface of the non-reinforced part of the shell 1 is deformed. After the impact, the force will be transmitted to the objects inside the horizontal support plate 81 through the receiving plate 91 and the docking plate 92 for driving, and some of it is dispersed in the horizontal support plate 81 itself and the longitudinal support plate 3.

[0049] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 In a further embodiment, the through groove 82 and the rectangular groove 83 are connected to each other, and the interior of the transverse support plate 81 is slidably connected with a connecting rack 84, and a portion of the docking plate 92 is slidably connected to the interior of the through groove 82 and fixedly connected to the connecting rack 84, and a linkage gear 85 is meshedly connected above the connecting rack 84, and a linkage rack 86 is meshedly connected above the linkage gear 85, and a top plate 87 is fixedly connected above the linkage rack 86, and a push block 88 is fixedly connected to the upper end of the top plate 87, and the linkage gear 85 is rotatably connected to the interior of the transverse support plate 81, and the linkage rack 86 and the top plate 87 are both slidably connected to the interior of the transverse support plate 81.

[0050] In this embodiment, the docking plate 92 is connected to the connecting rack 84 by bolts, so that the connecting rack 84 can move to the right when impacted, and after being transmitted by the linkage gear 85, the linkage rack 86 will move the top plate 87 and the push block 88 to the left, that is, move in the direction of the impact force, thereby pushing the slider 75; when the docking plate 92 is restricted by the through groove 82, part of the impact force will be transmitted to the horizontal support plate 81 itself, and then further dispersed.

[0051] Reference Figure 4 and Fig. 9 In a further embodiment, the panel 71 is provided with four slide grooves 72, the slider 75 is slidably connected inside the slide groove 72, the upper part of the push block 88 is slidably connected inside the slide groove 72 and is located on one side of the slider 75, both sides of the slider 75 are fixedly connected with connecting rods 73, and the side of the connecting rod 73 close to the raised sealing ring 62 is fixedly connected with evenly arranged top blocks 74, and the top blocks 74 are used to squeeze the recessed sealing ring 61 and the raised sealing ring 62 after they fit together.

[0052] In this embodiment, the limit rod 76 not only limits the sliding of the slider 75, but also prevents the slider 75 from rebounding by the tightly fitted concave sealing ring 61 and convex sealing ring 62 after the movement is completed through the engagement of the block 78 and the ratchet bar 77, thereby achieving the purpose of fixation; rectangular grooves are provided on both sides of the inlay plate 71, and the top block 74 is located in the rectangular groove, and the rectangular groove is connected to the slide groove 72.

[0053] Reference Fig. 9 and Fig.10 In a further embodiment, the limiting rod 76 is located inside the slider 75, and both ends of the limiting rod 76 are fixedly connected to the inner wall of the slide groove 72. A ratchet bar 77 is fixedly connected above the limiting rod 76, and a block 78 is slidably connected inside the slider 75. The block 78 fits with the ratchet bar 77, and a spring 79 is provided above the block 78.

[0054] In this embodiment, when the slider 75 is passively moved to the left, the block 78 will be lifted up by the ratchet bar 77, and after losing power, the rebound of the spring 79 will re-engage the bottom of the block 78 with the top of the ratchet bar 77; when the shell 1 and the end cover 5 are closed, the recessed sealing ring 61 and the raised sealing ring 62 are also closed. At this time, the top block 74 is in the same plane as the recessed sealing ring 61 and the raised sealing ring 62, and then when the top block 74 moves in the impact direction, it will squeeze the recessed sealing ring 61 and the raised sealing ring 62, so that the two fit more closely, and the two are connected more tightly to the edge groove of the shell 1, thereby increasing the connection strength between the shell 1 and the end cover 5.

[0055] Reference Figure 4 and Figure 7 In a further embodiment, the raised sealing ring 62 is fixedly connected to the bottom of the end cover 5, the raised sealing ring 62 surrounds the periphery of the panel 71, the bottom of the panel 71 is fixedly connected with a reinforcement grid 63, the buffer plug 64 has five staggered arrangements, and the buffer plug 64 is fixedly connected to both ends of the reinforcement grid 63.

[0056] In this embodiment, the reinforcement grid 63 is composed of three transverse reinforcement rods and two longitudinal reinforcement rods, which are used to increase the strength of both the end cover 5 and the panel 71, and connecting plates are provided at both ends of the transverse reinforcement rods, and the buffer plugs 64 are connected to the connecting plates, and the five buffer plugs 64 are inclined at an angle of twelve degrees to each other, fitting in the gap between the upper detour plate 94 and the upper curved plate 93.

[0057] Reference Figure 3 and Figure 5 In a further embodiment, the recessed sealing ring 61 is located below the raised sealing ring 62 and is fixedly connected to the inner side of the shell 1. A mounting plate 2 for mounting a battery is fixedly connected to the interior of the shell 1. The inner wall of the shell 1 and both sides of the longitudinal support plate 3 are fixedly connected with mounting sockets 4. The mounting sockets 4 are used for plugging and fixing the transverse support plate 81.

[0058] In this embodiment, the bottom of the mounting plate 2 is provided with a bent portion and a cooling plate for buffering the file; a groove is provided in the middle of the longitudinal support plate 3 for placing the wiring harness, and the longitudinal support plate 3 is also used to increase the longitudinal strength inside the shell 1, while the transverse support plate 81 is used to increase the transverse strength of the shell 1, and the non-reinforced part is taken over by the buffer mechanism 9 to perform lateral buffering.

[0059] The working principle of the present invention is as follows:

[0060] After the battery module is installed inside the housing 1, the end cover 5 and the housing 1 are closed by bolts, the raised sealing ring 62 is aligned with the recessed sealing ring 61, and the buffer plug 64 is aligned with both sides of the upper detour plate 94;

[0061] After installation, if an unexpected situation occurs in which the shell 1 is subjected to a strong impact from the side and the non-transverse support plate 81 is deformed, the upper curved plate 93, the concave-convex plate 98 and the lower curved plate 95 will first absorb the force of the deformation, and then the upper detour plate 94, the miter plate 97 and the lower detour plate 96 in the middle part will absorb it, and finally the upper curved plate 93, the concave-convex plate 98 and the lower curved plate 95 on the other side will absorb it, thereby blocking most of the impact force that causes the shell 1 to deform, and the other part of the impact will cause the receiving plate 91 to carry the docking plate 92 The connecting racks 84 in the two side horizontal support plates 81 are moved together, and the linkage racks 86 are driven by the linkage gear 85 to move the top plate 87 and the push block 88 in the opposite direction of the impact force, so that the push block 88 can push the slider 75 in the slide groove 72. The movement of the slider 75 will make the connecting rod 73 and the top block 74 move together, so that the top block 74 squeezes the concave sealing ring 61 and the convex sealing ring 62 that have been matched with each other to complete the enhanced sealing. In this process, this part of the impact force will be consumed;

[0062] When the slider 75 moves with the connecting rod 73 and the top block 74, the block 78 inside the slider 75 will also move, and the bottom of the block 78 fits the top of the ratchet strip 77, so the block 78 will be forced to move up and compress the spring 79 above the block 78 to further buffer. When the push block 88 loses the power to move, the impact force is completely consumed, and the spring 79 will move the block 78 down so that the block 78 fits the ratchet strip 77 again, avoiding the rebound of the concave sealing ring 61 and the convex sealing ring 62, and the block is stuck in place, which not only increases the sealing performance of the housing 1 and the end cover 5, but also increases the strength of the connection between the two.

[0063] When the recessed sealing ring 61 and the raised sealing ring 62 are squeezed by the top block 74 , they also have a certain buffering effect, and the buffer insert block 64 increases the impact resistance between the upper detour plate 94 and the upper curved plate 93 .

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
