Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle batteries, and in particular to a battery tray for new energy vehicles. Background Art

[0002] The battery tray of new energy vehicles is an important component of new energy vehicles and battery energy storage systems. It is mainly used to carry and fix the battery pack of new energy vehicles to ensure that the battery pack remains stable during vehicle driving. At the same time, it provides physical protection for the battery pack to resist external impact, collision, extrusion, and puncture from objects such as gravel.

[0003] However, in actual use, the existing battery tray is connected to the battery through rigid fixing methods such as gluing and screws. The car will be continuously subjected to dynamic loads such as vibration and bumps during driving. After long-term use, the rigidly connected components may fatigue and deform. For example, the screws may loosen due to long-term vibration, causing the installation position of the battery pack to change. Over time, the relative position between the battery packs may deviate from the initial design state, thereby affecting the battery's charging and discharging performance, reducing the battery's energy conversion efficiency, causing battery failure, and affecting the vehicle's power performance and cruising range. The offset position between the battery packs even increases the risk of mutual interference or even collision. Moreover, once a collision occurs between battery packs, it may also trigger a chain reaction, causing damage to the internal structure of the battery and causing local overheating.

[0015] Furthermore, the triangular block three is located on the moving path of the triangular block two, and the straight groove is located on the moving path of the transverse pressure plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Four right-angle airbags form a flexible clamp for the energy storage battery. This can effectively cushion the vibration and bumps caused by the new energy vehicle during driving, reducing the impact on the energy storage battery. Working together with the bolt connection, it forms a double protection for the energy storage battery, greatly reducing the possibility of screws loosening due to long-term vibration, thereby ensuring that the installation position of the energy storage battery is more stable and will not easily deviate from the initial design state, helping to maintain the normal charging and discharging performance of the energy storage battery, thereby ensuring the vehicle's power performance and cruising range.

[0018] The flexible clamping of the right-angle airbag can limit the movement range of the energy storage battery to a certain extent. Even when the new energy vehicle is subjected to large external forces, the relative displacement between multiple energy storage batteries can be effectively reduced. The right-angle airbag can act as a buffer, reducing the degree of damage to the internal structure of the energy storage battery, which greatly reduces the risk of mutual interference or even collision between multiple energy storage batteries. Compared with rigid connections, the flexible clamping right-angle airbag can absorb some of the collision energy, thereby reducing the occurrence of chain reactions and the risk of serious accidents such as battery fires caused by local overheating, thereby improving the safety of the battery system.

[0019] The right-angle airbags no longer fit the energy storage batteries. At this time, the energy storage batteries in a single cell no longer fit the right-angle airbags at its four corners, so that the outside of the energy storage battery is no longer blocked by the right-angle airbags. At the same time, because the energy storage batteries do not conflict with the side walls of the cells in a single cell, sufficient operating space is left for the user. The sufficient operating space allows the user to observe all parts of the battery more comprehensively, helps to timely discover potential fault hazards, and improves the accuracy and reliability of maintenance. With sufficient operating space, the user can use various maintenance tools more freely, reducing the risk of collision between the user and the energy storage battery and other equipment, avoiding the inconvenience of using tools and limited operation due to narrow space, and improving the efficiency and quality of maintenance work.

[0020] When the energy storage battery bulges and expands, if the right-angle airbags remain in a clamping state, additional pressure will be applied to the bulging energy storage battery, which may aggravate the damage inside the energy storage battery, such as further dislocation of electrode materials and rupture of the diaphragm. The exhaust and contraction of the right-angle airbags can reduce the clamping force of the four right-angle airbags on the energy storage battery, providing a certain buffer space for the battery expansion, reducing the internal pressure of the battery, avoiding excessive squeezing of the bulging energy storage battery, reducing the degree of damage to the internal structure of the energy storage battery, and preventing the energy storage battery failure from further deteriorating;

[0021] Through the connection between the plug end of the power cord and the connector, the guide column applies a thrust toward the connector, strengthening the connection between the power cord and the connector. This can provide additional pressure for the connection between the energy storage battery and the new energy vehicle, making the connection more secure and reliable. This stable connection can withstand the vibration and impact generated by new energy vehicles under various road conditions, preventing the plug end of the connector from shaking, shifting, or even falling off during vehicle driving, thereby reducing electrical failures and safety risks caused by loose connections.

[0022] By simultaneously disconnecting the plug-in end of the power cord from the connector, the new energy vehicle and the multiple energy storage batteries are disconnected. The user can then inspect the inside of the battery tray, and the multiple energy storage batteries are no longer discharging to the outside, thereby avoiding the risk of electric shock caused by accidental touch during the inspection and maintenance process. At the same time, it can prevent secondary damage to the energy storage battery caused by abnormalities in the electrical system of the new energy vehicle during the inspection and maintenance process. For example, an electrical fault on a new energy vehicle may cause current to flow back into the energy storage battery, damaging the internal structure of the energy storage battery. After disconnection, this situation can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] The present invention provides the following embodiments:

[0041] Example 1: Please refer to Figures 1 to 6 As shown, the battery tray of the new energy vehicle includes a battery tray 11 and multiple partitions 12. The multiple partitions 12 are arranged in a horizontal and vertical staggered manner. A plurality of independent cells arranged in a rectangular array are formed between the multiple partitions 12. Each cell of the multiple partitions 12 is provided with a storage battery 13. The multiple storage batteries 13 are fixedly connected to the upper surface of the inner wall of the battery tray 11 by bolts, and a top plate 16 is fixedly installed on the top of the battery tray 11 by bolts.

[0042] The single energy storage battery 13 is placed in the center of a single cell and is not in contact with any of the four side walls of the cell.

[0043] A stabilizing component is provided in a single cell, and the stabilizing component is used to flexibly stabilize the energy storage battery 13. The stabilizing component includes four triangular pillars 21, and the four triangular pillars 21 are fixedly connected to the four corners of the cell in a rectangular array. The bottom of each of the four triangular pillars 21 facing the energy storage battery 13 is fixedly connected to a telescopic rod 22. One end of the telescopic rod 22 connected to the triangular pillar 21 is a fixed end, and the other end is a telescopic end. The telescopic ends of the four telescopic rods 22 are each fixedly connected to a right-angle plate 23. A spring 24 is provided inside the four telescopic rods 22. The two ends of the four springs 24 are respectively fixedly connected to the triangular pillar 21 and the right-angle plate 23. The four triangular pillars 21 are close to one side of the telescopic rod 22 and are located above the telescopic rod 22 and are each fixedly connected to a bottom plate 25 , the top surfaces of the four bottom plates 25 are each fixedly connected to a telescopic rod 26, one end of the telescopic rod 26 connected to the bottom plate 25 is a fixed end, and the other end is a telescopic end, the telescopic ends of the four telescopic rods 26 are each fixedly connected to a pressure contact block 28, and a spring 27 is provided inside each of the four telescopic rods 26, and the two ends of the four springs 27 are respectively fixedly connected to the bottom plate 25 and the pressure contact block 28, and the top of the four right-angle plates 23 is fixedly connected to a triangular block 29 on one side facing the triangular pillar 21 on the same side, and the side of the four right-angle plates 23 away from the triangular block 29 is fixedly connected to a right-angle airbag 210, the pressure contact block 28 can be extended and slid in the direction of the telescopic rod 26 by contact with the top plate 16, and the triangular block 29 can be moved toward the energy storage battery 13 by sliding the pressure contact block 28.

[0044] The pressing block 28 is slidably connected to the triangular support 21 .

[0045] The pressing block 28 is configured to have a triangular opening on one side close to the triangular block 1 29 , and the triangular opening is complementary to the triangular block 1 29 .

[0046] Among them, the four corners of the energy storage battery 13 are located on the moving path of the four-corner right-angle airbag 210.

[0047] When the top plate 16 is not installed on the top surface of the battery tray 11 , the pressing block 28 is engaged with the triangular block 1 29 , and the top end of the pressing block 28 extends out of the top surface of the battery tray 11 .

[0048] There are two stages of use when the stabilizing component is used. The first stage is during the normal use of the new energy vehicle, that is, the top plate 16 is installed on the top surface of the battery tray 11 by bolts, and the battery tray 11 is installed on the new energy vehicle. The process of the top plate 16 being installed on the top surface of the battery tray 11 is as follows:

[0049] The user first aligns the top plate 16 with the installation position of the battery tray 11 and presses down the top plate 16 until the top plate 16 fits with the battery tray 11. During this process, the top plate 16 contacts the top surfaces of the four pressure contact blocks 28 in the cell and pushes the pressure contact blocks 28 downward, causing the pressure contact blocks 28 to slide downward on the triangular support 21. During this process, the triangular surface of the pressure contact block 28 pushes the triangular block 1 29 to move away from the triangular support 21, and the pressure contact block 28 presses down the telescopic end of the telescopic rod 26, causing the spring 2 27 to be elastic. At the same time, as the triangular block 29 moves, the triangular block 29 pushes the right-angle plate 23 and the right-angle airbag 210 to move synchronously toward the corners of the adjacent energy storage battery 13. At this time, the telescopic end of the telescopic rod 22 extends and stretches the spring 24 until the right-angle airbag 210 fits with the corners of the energy storage battery 13. At this time, the top plate 16 fits to the top surface of the battery tray 11. Then the user installs the top plate 16 on the battery tray 11 with bolts, thereby fixing the fitting state of the right-angle airbag 210 and the energy storage battery 13.

[0050] Since the energy storage battery 13 in a single cell is provided with a right-angle airbag 210 at each of its four corners, the four corners of the energy storage battery 13 are all contacted by the right-angle airbag 210. Due to the soft and tough characteristics of the right-angle airbag 210, the four right-angle airbags 210 form a flexible clamp for the energy storage battery 13. The flexible clamping of the right-angle airbag 210 can effectively buffer the vibration and bumps caused to the energy storage battery 13 during the driving of the new energy vehicle, reduce the impact on the energy storage battery 13, and work together with the bolt connection to form a double protection for the energy storage battery 13, greatly reducing the possibility of the screws loosening due to long-term vibration, thereby ensuring that the installation position of the energy storage battery 13 is more stable and will not easily deviate from the initial design state, which helps to maintain the normal charging and discharging performance of the energy storage battery 13, thereby ensuring the vehicle's power performance and cruising range.

[0051] In addition, the flexible clamping of the right-angle airbag 210 can limit the movement range of the energy storage battery 13 to a certain extent. Even when the new energy vehicle is subjected to a large external force, the relative displacement between multiple energy storage batteries 13 can be effectively reduced. The right-angle airbag 210 can play a buffering role and reduce the degree of damage to the internal structure of the energy storage battery 13, which greatly reduces the risk of mutual interference or even collision between multiple energy storage batteries 13. Compared with a rigid connection, the flexibly clamped right-angle airbag 210 can absorb part of the collision energy, reduce the risk of serious accidents such as local overheating and fire, and improve the safety of the battery system.

[0052] Another use stage of the stabilizing assembly is when the battery system of the new energy vehicle fails and the user needs to remove the top plate 16 to inspect the multiple energy storage batteries 13 inside the battery tray 11, as follows:

[0053] At this time, the user removes the top plate 16 from the battery tray 11. At this time, the top plate 16 no longer restricts the elastic extension of the spring 27. Under the action of the elastic extension of the spring 27, the pressure contact block 28 is pushed to slide upward on the triangular support 21. In this process, the pressure contact block 28 moves to a position where its triangular opening fits with the triangular block 1 29. At this time, under the action of the elastic contraction of the spring 1 24, the right-angle plate 23 is pulled toward the triangular support 21, so that the pressure contact block 28 fits with the triangular block 1 29. At this time, the right-angle plate 23 drives the right-angle airbag 210 to move synchronously, so that the right-angle airbag 210 is no longer in contact with the energy storage battery 13. At this time, the energy storage battery 13 in a single cell is no longer in contact with its four The right-angle airbag 210 fits the corners, so that the outside of the energy storage battery 13 is no longer blocked by the right-angle airbag 210. At the same time, since the energy storage battery 13 does not conflict with the side wall of the cell in a single cell, sufficient operating space is left for the user. The sufficient operating space allows the user to observe various parts of the battery more comprehensively, which helps to timely discover potential fault hazards and improve the accuracy and reliability of maintenance. With sufficient operating space, the user can use various maintenance tools more freely, reducing the risk of collision between the user and the energy storage battery 13 and other equipment, avoiding the inconvenience of using tools and limited operation due to narrow space, and improving the efficiency and quality of maintenance work.

[0054] Example 2: Reference Figures 6 to 8 As shown, an expansion component is provided in a single cell, and the expansion component is used to exhaust the right-angle airbag 210 while the energy storage battery 13 is inflated, so that the clamping force of the right-angle airbag 210 on the energy storage battery 13 is reduced. The expansion component includes four air tubes 1 31, and the four air tubes 1 31 are fixedly connected in a rectangular array at the bottom of the side of the four right-angle airbags 210 adjacent to each other. The middle of one of the air tubes 1 31 is fixedly connected to an air tube 2 32, and the end of the air tube 2 32 away from the air tube 1 31 is fixedly connected to a micro air pump 33. An elastic rope 34 is fixedly connected between the middle parts of the side walls of the four adjacent right-angle airbags 210, and an electric contact block 1 35 is fixedly connected to the middle parts of the four elastic ropes 34. A horizontal plate 36 is fixedly connected between the top ends of the telescopic ends of the two telescopic rods 26 located on one side of the micro air pump 33, and a contact column 37 is fixedly connected to the lower surface of the middle part of the horizontal plate 36. An electric contact block 2 38 is installed on the top of the micro air pump 33.

[0055] Wherein: the micro air pump 33 is fixedly connected to the side wall of the cell.

[0056] The second electric contact block 38 is located on the moving path of the contact post 37 .

[0057] Among them: there is an electrical connection between the four electric contact blocks 35 and the micro air pump 33, and there is an electrical connection between the electric contact block 2 38 and the micro air pump 33. Specifically, when the electric contact block 1 35 is in contact with the energy storage battery 13, the electric contact block 1 35 controls the micro air pump 33 to inhale air in a fixed amount, so that the micro air pump 33 passes through the trachea 2 32 and the trachea 1 31, so that the four right-angle airbags 210 are exhausted and shrunk. When the electric contact block 2 38 is in contact with the contact column 37, the electric contact block 2 38 controls the micro air pump 33 to blow air in a fixed amount, so that the micro air pump 33 passes through the trachea 2 32 and the trachea 1 31, so that the right-angle airbag 210 is inflated and expanded until it contacts the energy storage battery 13.

[0058] Among them: because the elastic rope 34 is fixed to the middle part of the side wall of the right-angle airbag 210, there is a gap between the electric contact block 35 and the energy storage battery 13. This gap prevents the energy storage battery 13 from contacting the electric contact block 35 when the energy storage battery 13 does not expand.

[0059] When the expansion assembly is in use, there are two stages of use, one of which is when the top plate 16 is pressing down the contact block 28, as follows:

[0060] At this time, the pressure contact block 28 moves downward, and at the same time, the telescopic end of the second telescopic rod 26 contracts downward, driving the horizontal plate 36 and the contact post 37 to move downward synchronously until the bottom end of the contact post 37 contacts the second electric contact block 38. At this time, the micro air pump 33 blows air and cooperates with the second air pipe 32 and the first air pipe 31 to inflate the four right-angle airbags 210, so that the four right-angle airbags 210 are all inflated and expanded. The four right-angle airbags 210 contact the four corners of the energy storage battery 13, providing a material basis for stabilizing the operation of the component.

[0061] In another use stage, the energy storage battery 13 is expanded due to overcharge, overdischarge, wear and tear during use during use of the new energy vehicle. At this time, the expanded energy storage battery 13 bulges outward, and the bulged part of the energy storage battery 13 contacts the electric contact block 1 35, so that the electric contact block 1 35 controls the micro air pump 33 to exhaust and shrink the right-angle airbag 210. At this time, as the right-angle airbag 210 exhausts and shrinks, the electric contact block 1 35 moves away from the energy storage battery 13, so that the electric contact block 1 35 no longer contacts the bulged part of the energy storage battery 13. The exhaust and contraction of the corner airbags 210, when the energy storage battery 13 bulges and expands, if the right-angle airbags 210 still maintain a clamping state, it will exert additional pressure on the bulging energy storage battery 13, which may aggravate the damage inside the energy storage battery 13, such as causing further dislocation of the electrode material and rupture of the diaphragm. The clamping force of the four right-angle airbags 210 on the energy storage battery 13 is reduced, providing a certain buffer space for the expansion of the battery, reducing the internal pressure of the battery, avoiding excessive squeezing of the bulging energy storage battery 13, and reducing the degree of damage to the internal structure of the energy storage battery 13.

[0062] Example 3: Reference Figures 10 to 12 As shown, a connecting seat 15 is installed on the top of the inner wall of the battery tray 11, and multiple energy storage batteries 13 inside the battery tray 11 are connected to each other. One of the energy storage batteries 13 is installed with a power cord 14. The end of the power cord 14 close to the connecting seat 15 is plugged into the connecting seat 15, and the end of the power cord 14 plugged into the connecting seat 15 is set as a plug-in end. A power-off component is provided on the battery tray 11. The power-off component is used to stabilize the connection between the power cord 14 and the connecting seat 15, and to disconnect the power cord 14 from the connecting seat 15 when the energy storage battery 13 needs to be repaired. The power-off component includes a connecting block 41. The plug-in end of the power cord 14 is fixedly connected to the connecting block 41. The connecting block 41 There are two guide columns 42 symmetrically slidably connected on the upper surface, and a spring three 43 is respectively provided on the surface of the two guide columns 42. The two ends of the two spring threes 43 are respectively fixedly connected to the connecting seat 15 and the connecting block 41. The tops of the pressure contact blocks 28 in the two cells on both sides of the connecting seat 15 are jointly fixedly connected with a horizontal pressure plate 44. Two connecting rods 45 are symmetrically fixedly connected to the lower surface of the middle part of the horizontal pressure plate 44. A triangular block two 46 is fixedly connected between the bottom ends of the two connecting rods 45. A triangular block three 47 is fixedly connected to the bottom surface of the connecting block 41. The triangular block two 46 is located at the bottom of the triangular block three 47. A straight groove 48 is respectively provided on the two cells at the bottom of the horizontal pressure plate 44.

[0063] Among them: the triangular block 3 47 is located on the moving path of the triangular block 2 46 .

[0064] The straight groove 48 is located on the moving path of the horizontal pressure plate 44 .

[0065] When the power-off assembly is in use, there are two stages of use. The first stage is when the top plate 16 is installed on the battery tray 11, that is, when the pressure contact block 28 is pressed down, the spring 3 43 is in an elastically stretched state, as follows:

[0066] At this time, the pressure contact block 28 is pressed down, driving the horizontal pressure plate 44 to be pressed down synchronously. In the process of the horizontal pressure plate 44 being pressed down, the triangular block 2 46 is driven to move downward synchronously through the connecting rod 45. At this time, the triangular block 2 46 is no longer restricted by the elastic reset of the spring 3 43 through the triangular block 3 47. With the elastic reset of the spring 3 43, the connecting block 41 slides on the surface of the guide column 42 toward the connecting seat 15. With the movement of the connecting block 41, the connecting block 41 drives the plug end of the power cord 14 to be connected to the connecting seat 15. At this time, the new energy vehicle is connected to the multiple energy storage batteries 13 for power supply, and At this time, the connection between the plug-in end of the power cord 14 and the connecting socket 15 is pushed toward the connecting socket 15 by the guide column 42, which strengthens the connection between the power cord 14 and the connecting socket 15. It can provide additional pressure for the connection between the energy storage battery 13 and the new energy vehicle, making the connection more firm and reliable. This stable connection can withstand the vibration and impact force generated by new energy vehicles under various road conditions, prevent the plug-in end of the connecting socket 15 from shaking, displacing or even falling off during the driving of the vehicle, and reduce electrical failures and safety risks caused by loose connections.

[0067] Another use stage of the power-off component is when the battery system of the new energy vehicle fails and the user needs to remove the top plate 16 to inspect the multiple energy storage batteries 13 inside the battery tray 11, that is, when the pressure contact block 28 is lifted, the details are as follows:

[0068] At this time, as the pressure contact block 28 is lifted, the triangular block 2 46 is driven to move up synchronously. In the process of the triangular block 2 46 moving up, the triangular block 2 46 contacts the inclined surface of the triangular block 3 47, causing the triangular block 3 47 to move away from the connecting seat 15. At this time, the triangular block 3 47 drives the connecting block 41 to move synchronously and stretches the spring 3 43, so that the plug-in end of the power cord 14 is synchronously disconnected from the inside of the connecting seat 15. At this time, the new energy vehicle is disconnected from the multiple energy storage batteries 13. At this time, the user can inspect the inside of the battery tray 11, and the multiple energy storage batteries 13 are no longer discharging to the outside, which can avoid the risk of electric shock caused by accidental touch during the inspection process. At the same time, it can prevent the energy storage battery 13 from causing secondary damage due to abnormalities in the electrical system of the new energy vehicle during the inspection process. For example, an electrical fault on the new energy vehicle may cause the current to flow back into the energy storage battery 13, damaging the internal structure of the energy storage battery 13. After disconnection, this situation can be effectively avoided.
