Description

Technical Field

[0001] This invention relates to the field of new energy battery tray technology, specifically to an impact-resistant, structurally reinforced new energy battery tray. Background Technology

[0002] The core component of new energy vehicles is undoubtedly the vehicle's power battery, which is the energy source of these vehicles and directly determines their driving range. Ternary lithium batteries and lithium iron phosphate batteries are the dominant applications in both passenger and commercial vehicles. Currently, passenger vehicle batteries are mainly ternary lithium batteries, while commercial vehicle batteries are mainly lithium iron phosphate batteries.

[0003] The main types of battery trays are as follows: (1) Steel battery trays: The main material used for steel battery trays is high-strength steel, which is economical and has excellent processing and welding functions. In actual road conditions, the battery trays are affected by different working conditions, such as being easily impacted by gravel, and steel trays have good resistance to stone impact. However, due to its poor rigidity, steel battery trays are prone to compression deformation during collision, which can damage the battery or even cause a fire. (2) Die-cast aluminum battery trays: Cast aluminum battery trays have high comprehensive mechanical properties, but the elongation of cast aluminum alloy is low, and it is easy to deform after a collision. (3) Extruded aluminum battery trays: Extruded aluminum alloy battery trays have high rigidity, vibration resistance, compression and impact resistance, and the frame structure is more conducive to lightweighting and strength assurance of different structures.

[0004] Therefore, this invention optimizes the problems existing in the above-mentioned tray by designing an impact-resistant, structurally reinforced new energy battery tray. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an impact-resistant, structurally reinforced new energy battery tray.

[0006] The technical solution of the present invention is: an impact-resistant structurally reinforced new energy battery tray, comprising a tray body, the tray body including an auxiliary tray and a reinforcing tray, and a cooling system provided at the bottom of the auxiliary tray;

[0007] The reinforcing tray is provided with a first sinking groove, the auxiliary tray is located in the first sinking groove, and the auxiliary tray is provided with a second sinking groove and a plurality of partitions that divide the second sinking groove into a plurality of first cavities.

[0008] A second cavity is formed between the auxiliary tray and the first sink. Each of the opposite side walls of the reinforcing tray has a through hole. An impact-resistant structure is provided in the through hole. The impact-resistant structure includes a rotating frame, a plurality of elastic rods arranged at intervals in the rotating frame, a first spring, and an airbag.

[0009] The upper and lower ends of the rotating frame are connected to the top and bottom of the through hole respectively by fixed rods; the elastic rod is connected to the top and bottom of the rotating frame by hinge rods; one end of the first spring is fixedly connected to the side wall of the through hole, and the other end of the first spring is fixedly connected to the side wall of the rotating frame.

[0010] The auxiliary tray has a third cavity in its inner wall, and the compressible part of the airbag is located in the third cavity facing the through hole. The top load-bearing part of the airbag penetrates the side wall of the auxiliary tray, and the airbag is filled with a non-Newtonian fluid.

[0011] The second settling tank has a first screw on one side wall and an elastic snap-fit ​​block on the other side wall; one end of the partition plate has a first screw hole that is threaded to the first screw, and the other end of the partition plate has a snap-fit ​​hole that snaps to the snap-fit ​​block.

[0012] An air pump is installed inside the partition, and small holes are provided on the sides of the partition. The push-button switch of the air pump is connected to the first screw.

[0013] Furthermore, the elastic rod is rotatably connected to the hinge rod, and the surface of the elastic rod is a smooth surface.

[0014] Explanation: By rotating the smooth elastic rod to connect it to the hinge rod, when the elastic rod receives an impact, it can both elastically indent in the direction of the impact to offset part of the impact force and guide and disperse the impact force through rotation, thereby further enhancing the buffering effect against the impact force.

[0015] Furthermore, two adjacent elastic rods are fixedly connected by an elastic plate, and the adjacent elastic plates are arranged in opposite directions.

[0016] Explanation: By setting elastic plates with different orientations, when the elastic rod is indented under force, the elastic plate on one side that is indented stretches the adjacent elastic rod to prevent the elastic rod from detaching from the hinge rod under excessive impact force, while the elastic plate on one side that is protruding is pulled by the elastic rod to get closer to the impacting object and block it, thus protecting the elastic rod and improving its impact resistance.

[0017] Furthermore, each of the first settling troughs corresponding to the other set of opposite sidewalls of the reinforced pallet is provided with a buffer structure. The buffer structure includes multiple positioning rods fixedly installed on the outer sidewall of the auxiliary pallet and the sidewall of the first settling trough, and multiple shock-absorbing rods installed between the outer sidewall of the auxiliary pallet and the inner wall of the first settling trough.

[0018] The positioning rod and the damping rod located on the same side are hinged together in sequence by a connecting plate. The damping rods close to the side walls of the first settling tank are respectively fixedly connected to the corresponding side walls of the first settling tank by a second spring, and the two opposing positioning rods are connected by a third spring.

[0019] Explanation: By setting up a buffer structure, auxiliary resistance can be provided in the vertical direction of the impact-resistant structure; by hinged the shock-absorbing rod to the positioning rod with the connecting plate, the positioning rod disperses the force to the connecting plate when subjected to impact, and the shock-absorbing rod in the middle cancels it out.

[0020] Furthermore, the shock-absorbing rods at both ends are connected to the first sink groove through the second spring, which can use the elastic force of the spring to buffer the force to a certain extent and provide a certain resistance to the shock-absorbing rods.

[0021] The third spring serves two purposes: firstly, it forms a triangular structure within the buffer structure, making it more stable; secondly, the spring's elasticity buffers the impact on the positioning rod.

[0022] Furthermore, anti-collision pads are provided at the corners of multiple first cavities; the anti-collision pads located at the corners of the second settling tank are fixedly installed at the corners of the second settling tank, and the anti-collision pads located inside the second settling tank are fixedly installed on the side of the partition.

[0023] Explanation: By setting anti-collision pads, the corners of the battery are buffered to prevent the corners from colliding with the auxiliary tray and being damaged when the battery is impacted and shaken. Some of the anti-collision pads are set on the partition, which can adjust the size of the first cavity according to the size of the battery, so as not to affect the placement of the battery.

[0024] As an optional embodiment of the present invention, the bottom of the auxiliary tray is fixedly connected to the bottom of the inner tray of the reinforcing tray.

[0025] Note: By fixing the auxiliary tray to the reinforcing tray, the side wall of the auxiliary tray can provide a certain amount of support to maintain the overall stability.

[0026] Furthermore, the second settling trough sidewall is provided with a sliding plate and a first sliding groove that are slidably connected thereto. One end of the sliding plate is rotatably connected to one end of a second screw that penetrates the bottom of the auxiliary tray, and the other end of the sliding plate is fixedly connected to the top of the sliding groove through a first spring rod. The other end of the second screw is rotatably connected to a second screw hole provided at the bottom of the reinforcing tray.

[0027] Explanation: By setting up a slider and a first spring rod, the slider can automatically spring back to its initial position after the battery is removed, without affecting the next use; by setting up a second screw and a second screw hole, the connection between the auxiliary tray and the reinforcing tray is strengthened when loading the battery, so that the whole can maintain better stability when subjected to impact.

[0028] As another alternative to the present invention, the bottom of the auxiliary tray is slidably connected to the bottom of the inner side of the reinforcing tray.

[0029] Note: The auxiliary tray is slidably connected to the reinforcing tray. When subjected to impact, the auxiliary tray can slide in the direction of impact under the action of the buffer structure, thereby reducing the force on the auxiliary tray and improving the impact resistance of the battery tray.

[0030] Furthermore, multiple liquid cooling pipes are provided between the bottom of the auxiliary tray and the bottom of the first settling tank. The liquid cooling pipes correspond one-to-one with the second sliding grooves provided at the bottom of the first settling tank. A liquid bladder is provided between two opposing positioning rods. One end of the liquid bladder is connected to the liquid cooling pipe, and the upper end of the liquid cooling pipe contacts the bottom of the auxiliary tray through a heat spreader.

[0031] The liquid cooling pipe is provided with multiple flow limiting devices that are connected to the liquid cooling pipe. Each flow limiting device contains an impeller that is sealed and rotatably connected to the flow limiting device, and two flow limiting blocks located on both sides of the impeller and symmetrical about the center of the impeller.

[0032] The upper end of the impeller shaft passes through the flow limiting component and is provided with a pressure plate. The pressure plate is slidably connected to the shaft, and the lower end of the pressure plate is provided with a pressure ring connected to it through multiple second spring rods.

[0033] The bottom of the auxiliary tray, the liquid cooling pipe, and the bottom of the reinforced tray are all made of copper.

[0034] Explanation: When the auxiliary tray slides left and right, the buffer structures on both sides alternately squeeze the liquid bladder, converting the kinetic energy generated by the sliding into the liquid energy of the liquid flow. This causes the coolant in the liquid cooling pipe to flow under the squeezing action of the liquid bladder. By setting up impellers and flow restrictors, the coolant flows left and right in the liquid cooling pipe, improving the heat exchange efficiency of the coolant in the liquid cooling pipe, thereby enhancing the heat dissipation effect on the battery. The liquid cooling pipe setup enhances heat dissipation while positioning and guiding the sliding of the auxiliary tray. Furthermore, the use of copper material for related components achieves good thermal conductivity and heat dissipation.

[0035] By setting up components such as pressure plates, the impeller speed can be adjusted by the pressure effect of the top cover on the auxiliary tray, thereby adjusting the flow rate of the coolant, which in turn affects the expansion and contraction of the liquid bladder, and further controls the buffering force of the buffer structure.

[0036] The beneficial effects of this invention are:

[0037] (1) The new energy battery tray of the present invention has an impact-resistant structure, so that when the battery tray is impacted, the rotating frame reduces part of the impact force by rotating inward and deflects the impact object by rotating outward, thereby dispersing the impact force.

[0038] Furthermore, the rotating frame and the reinforcing tray are connected by a spring. The spring can provide a certain support force to the rotating frame, converting it into resistance to impact. On the other hand, it can pull the rotating frame back to its initial position after the impact, so as not to affect the performance of the next use.

[0039] (2) The new energy battery tray of the present invention provides an elastic rod in the rotating frame. Because the elastic rod is elastic, it can buffer the impact force by indenting inward.

[0040] Furthermore, when the elastic rod is recessed to a certain extent, it compresses the airbag, causing the non-Newtonian fluid inside the airbag to flow into the inner wall of the auxiliary tray. When the non-Newtonian fluid is subjected to impact, it becomes relatively solid, generating a certain impact resistance and providing good protection for the auxiliary tray.

[0041] (3) The new energy battery tray of the present invention has an air pump installed in the partition. After the partition is connected to the auxiliary tray, the first screw enters through the rotation of the partition and starts the air pump switch. Thus, the battery is adsorbed through the small holes in the partition. Therefore, when subjected to impact, it has a certain stabilizing and anti-slip effect on the battery.

Detailed Implementation

[0054] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0055] Example 1

[0056] An impact-resistant, structurally reinforced new energy battery tray, such as Figure 1 As shown, the device includes a tray body, which includes an auxiliary tray 1 and a reinforcing tray 2. The bottom of the auxiliary tray 1 is equipped with a cooling system, which is existing technology.

[0057] like Figure 1 As shown, the bottom of the auxiliary tray 1 is fixedly connected to the bottom of the inner side of the reinforcing tray 2;

[0058] like Figure 3 , Figure 4 as well as Figure 6 As shown, the second settling tank sidewall is provided with a sliding plate 112 and a first sliding groove that are slidably connected thereto. One end of the sliding plate 112 is rotatably connected to one end of the second screw 114 that penetrates the bottom of the auxiliary tray 1. The other end of the sliding plate 112 is fixedly connected to the top of the sliding groove through the first spring rod 113. The other end of the second screw 114 is rotatably connected to the second screw hole 23 provided at the bottom of the inner sidewall of the reinforcing tray 2.

[0059] like Figure 1As shown, the reinforcing tray 2 is provided with a first sinking groove, the auxiliary tray 1 is located in the first sinking groove, and the auxiliary tray 1 is provided with a second sinking groove and a plurality of partitions 11 that divide the second sinking groove into a plurality of first cavities;

[0060] like Figure 1 As shown, anti-collision pads 111 are provided at the corners of multiple first cavities; the anti-collision pads 111 located at the corners of the second settling tank are fixedly installed at the corners of the second settling tank, and the anti-collision pads 111 located inside the second settling tank are fixedly installed on the side of the partition 11.

[0061] like Figure 1 As shown, a second cavity is formed between the auxiliary tray 1 and the first sink. The reinforcing tray 2 has through holes on a set of front and rear opposite side walls. An impact-resistant structure is provided in the through holes. The impact-resistant structure includes a rotating frame 21, multiple elastic rods 211 arranged at intervals in the rotating frame 21, a first spring 214, and an airbag 13.

[0062] like Figure 1 As shown, the upper and lower ends of the rotating frame 21 are connected to the top and bottom of the through hole respectively via fixed rods 212; the elastic rod 211 is connected to the inner top and inner bottom of the rotating frame 21 via hinge rods 213; one end of the first spring 214 is fixedly connected to the side wall of the through hole, and the other end of the first spring 214 is fixedly connected to the side wall of the rotating frame 21; the elastic rod 211 is rotatably connected to the hinge rod 213, and the surface of the elastic rod 211 is a smooth surface;

[0063] like Figure 1 and Figure 2 As shown, the inner wall of the auxiliary tray 1 is provided with a third cavity, the compressible part of the airbag 13 is disposed in the third cavity facing the through hole, the top load-bearing part of the airbag 13 penetrates the side wall of the auxiliary tray 1, and the airbag 13 is filled with a non-Newtonian fluid.

[0064] like Figure 1 and Figure 2 As shown, the first settling trough corresponding to the other set of left and right opposite side walls of the reinforced pallet 2 is provided with a buffer structure. The buffer structure includes twenty positioning rods 22 fixedly installed on the outer side wall of the auxiliary pallet 1 and the side wall of the first settling trough, and ten shock-absorbing rods 222 installed between the outer side wall of the auxiliary pallet 1 and the inner wall of the first settling trough.

[0065] like Figure 1 and Figure 2As shown, the positioning rod 22 and the damping rod 222 located on the same side are hinged together by the connecting plate 221 in sequence. The damping rods 222 near the front and rear side walls of the first settling tank are respectively fixedly connected to the corresponding side walls of the first settling tank by a second spring 223, and the two opposing positioning rods 22 are connected by a third spring 224.

[0066] like Figure 3 and Figure 4 As shown, a first screw 15 is provided on one side wall of the second settling tank, and a spring-loaded snap-fit ​​block 14 is provided on the other side wall of the second settling tank.

[0067] like Figure 5 As shown, one end of the partition 11 is provided with a first screw hole 116 that is threadedly connected to the first screw 15, and the other end of the partition 11 is provided with a snap hole that is snapped into the snap block 14.

[0068] like Figure 5 As shown, a suction pump 12 is provided inside the partition 11, and small holes 115 are provided on the sides of the partition 11. The push-button switch of the suction pump 12 is in contact with the first screw 15.

[0069] The working principle of the above-mentioned impact-resistant reinforced new energy battery tray is as follows: When the battery tray is impacted, the reinforced tray 2 is the first to bear the impact force. When the impact-resistant structure of the reinforced tray 2 is subjected to force, the rotating frame 21 reduces part of the impact force by rotating inward and deflects the impact object by rotating outward, thereby dispersing the impact force.

[0070] Furthermore, the rotating frame 21 and the reinforcing tray 2 are connected by a first spring 214. The first spring 214 can provide a certain support force to the rotating frame 21, which can be converted into resistance to impact. On the other hand, it can pull the rotating frame 21 back to its initial position after the impact, so as not to affect the effect of the next use.

[0071] An elastic rod 211 is provided inside the rotating frame 21. Because the elastic rod 211 is elastic, it can buffer the impact force by indenting inward. Furthermore, by rotating the smooth elastic rod 211 to the hinge rod 213, when the elastic rod 211 receives an impact, it can offset part of the impact force by elastically indenting in the direction of impact, and guide and disperse the impact force by rotating, thereby further enhancing the buffering of the impact force.

[0072] Furthermore, when the impact force is too great, the elastic rod 211 will be squeezed to a certain extent when it is concave, which will cause the non-Newtonian fluid in the airbag 13 to be squeezed and flow into the inner wall of the auxiliary tray 1. The non-Newtonian fluid will become relatively solid when subjected to impact, which will produce a certain impact resistance and provide good protection for the auxiliary tray 1.

[0073] After the impact ends, the non-Newtonian fluid, no longer under force, returns to its relative liquid state. The elastic rod 211 automatically and elastically returns to the rotating frame 21, and the airbag 13, no longer under pressure, automatically returns to normal, thereby drawing the non-Newtonian fluid back into the airbag 13 for recycling.

[0074] An air pump 12 is installed inside the partition 11. After the partition 11 is connected to the auxiliary tray 1, the first screw 15 rotates inside the partition 11 until the partition 11 is in contact with the auxiliary tray 1. Then, the first screw 15 presses the switch of the air pump 12 to start it. The air pump 12 then starts to generate suction, which attracts the battery through the small holes 115 on the partition 11. Therefore, when subjected to impact, it plays a certain role in stabilizing and preventing the battery from slipping.

[0075] Furthermore, by setting anti-collision pads 111 on the partition 11 and the auxiliary tray 1, the corners of the battery are buffered to prevent the corners of the battery from colliding with the auxiliary tray 1 and being damaged when the battery is subjected to impact and shaking. Some of the anti-collision pads 111 are set on the partition 11, so that the size of the first cavity can be adjusted by the partition 11 according to the different battery sizes, so as not to affect the placement of the battery.

[0076] By setting up a buffer structure, the left and right sides of the reinforced pallet 2 can provide auxiliary resistance to the impact-resistant structures on the front and rear sides of the reinforced pallet 2. By hinged the shock-absorbing rod 222 to the positioning rod 22 via the connecting plate 221, the positioning rod 22 on the reinforced pallet 2 disperses the force to the connecting plate 221 when subjected to impact, and the shock-absorbing rod 222 in the middle further offsets the force, while the positioning rod 22 on the auxiliary pallet 1 provides some resistance.

[0077] Furthermore, the shock-absorbing rods 222 at both ends are connected to the first sink groove through the second spring 223. The elastic force of the second spring 223 can buffer the force transmitted to both sides of the shock-absorbing rods 222 and provide a certain resistance to the shock-absorbing rods 222.

[0078] The third spring 224 is provided to form a triangular structure within the buffer structure, making the buffer structure more stable. On the other hand, the elastic force of the third spring 224 buffers the force on the impacted positioning rod 22.

[0079] By fixing the auxiliary tray 1 to the reinforcing tray 2, the side wall of the auxiliary tray 1 can provide a certain support force to maintain the overall stability.

[0080] By setting the slider 112 and the first spring rod 113, when the battery is loaded, the battery presses down and drives the slider 112 to slide in the first groove. As a result, the second screw 114 rotates under pressure and is threadedly connected to the second screw hole 23 at the bottom of the reinforcing tray 2, which strengthens the connection between the auxiliary tray 1 and the reinforcing tray 2, so that the whole can maintain better stability when subjected to impact.

[0081] Furthermore, after the battery is removed, the slider 112 can automatically spring back to its initial position through the retraction of the first spring rod 113, without affecting the next use.

[0082] Example 2

[0083] This embodiment is basically the same as embodiment 1, except that, as Figure 7 As shown, two adjacent elastic rods 211 are fixedly connected by an elastic plate 215, and the adjacent elastic plates 215 are arranged in opposite directions.

[0084] The working principle of this embodiment differs from that of Embodiment 1 in that, by setting elastic plates 215 with different directions, when the elastic rod 211 is indented under force, the elastic plate 215 indented on one side stretches the adjacent elastic rod 211 to prevent the elastic rod 211 from detaching from the hinge rod 213 under excessive impact force, and the elastic plate 215 protruding on one side is pulled by the elastic rod 211 to approach the impactor and block it, thus protecting the elastic rod 211 and improving its impact resistance.

[0085] Example 3

[0086] This embodiment is basically the same as embodiment 1, except that, as Figure 8 and Figure 9 As shown, the bottom of the auxiliary tray 1 is slidably connected to the bottom of the reinforcing tray 2; six liquid cooling pipes 226 are provided between the bottom of the auxiliary tray 1 and the bottom of the first settling tank, and the liquid cooling pipes 226 correspond one-to-one with the second sliding grooves 24 provided at the bottom of the first settling tank. A liquid bladder 225 is provided between two opposing positioning rods 22, one end of the liquid bladder 225 is connected to the liquid cooling pipe 226, and the upper end of the liquid cooling pipe 226 contacts the bottom of the auxiliary tray 1 through a heat spreader plate.

[0087] like Figure 10 As shown, the liquid cooling pipe 226 is provided with five flow limiting components 2261 that are connected to the liquid cooling pipe 226. Each flow limiting component 2261 is provided with an impeller 2262 that is sealed and rotatably connected to the flow limiting component 2261, and two flow limiting blocks 2263 located on both sides of the impeller 2262 and symmetrical about the center of the impeller 2262.

[0088] like Figure 11As shown, the upper end of the shaft 2264 of the impeller 2262 passes through the flow limiting member 2261 and is provided with a pressure plate 2265. The pressure plate 2265 is slidably connected to the shaft 2264, and the lower end of the pressure plate 2265 is provided with a pressure ring connected to it through multiple second spring rods.

[0089] The bottom of the auxiliary tray 1, the liquid cooling pipe 226, and the bottom of the reinforcing tray 2 are all made of copper.

[0090] The working principle of this embodiment differs from that of embodiment 1 in that the auxiliary tray 1 and the reinforcing tray 2 are slidably connected. When the auxiliary tray 1 is impacted, it can slide in the direction of impact under the action of the buffer structure, thereby reducing the force on the auxiliary tray 1 and improving the impact resistance of the battery tray.

[0091] Furthermore, when the vehicle is in motion or subjected to an impact, the auxiliary tray 1 slides left and right. The buffer structures on both sides alternately compress the liquid bladder 225, converting the kinetic energy generated by the sliding into the liquid energy of the flowing liquid. This causes the coolant in the liquid-cooled pipe 226 to flow under the compression of the liquid bladder 225. By setting up the impeller 2262 and the flow-limiting plate 2263, the coolant flows left and right within the liquid-cooled pipe 226, improving the heat exchange efficiency of the coolant within the liquid-cooled pipe 226, thereby enhancing the heat dissipation effect on the battery. The liquid-cooled pipe 226 also acts as a guide rail, thus enhancing heat dissipation while positioning and guiding the sliding of the auxiliary tray 1. Moreover, the use of copper material in the relevant components achieves excellent thermal conductivity and heat dissipation.

[0092] By setting up components such as pressure plate 2265, the speed of impeller 2262 can be adjusted by the pressure effect of the top cover (not shown in the figure) on the auxiliary tray 1, thereby adjusting the flow rate of coolant, which in turn affects the expansion and contraction of liquid bladder 225, and further controls the buffering force of the buffer structure.
