Description

Technical Field

[0001] This utility model relates to the field of vehicle battery protection technology, specifically a multi-angle reinforcement structure for vehicle batteries. Background Technology

[0002] Vehicle batteries are a core component of new energy vehicles (such as battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs)) and some traditional fuel vehicles. On the one hand, they provide power to the drive motor of electric vehicles, determining the vehicle's range, acceleration performance, and charging efficiency. On the other hand, they are used for vehicle starting, powering onboard electronic devices (such as dashboards, lights, and audio systems), and activating and controlling high-voltage systems. Vehicle batteries are not only the "heart" of electric vehicles but also a key technology for promoting carbon neutrality in the automotive industry. Their performance improvements directly determine the speed of popularization of new energy vehicles.

[0003] However, most current vehicle battery packs rely primarily on unidirectional reinforcing ribs or flat protective plates for protection. For example, longitudinal reinforcing ribs are simply parallel metal ribs placed at the top or bottom of the battery pack, mainly used to resist vertical compression (such as bottom scraping or stacking pressure). Flat protective plates, on the other hand, are steel or aluminum alloy plates installed on the sides of the battery pack, which can only cope with frontal collisions, but are less effective at protecting against oblique impacts or torsional forces.

[0004] Based on this, a multi-angle reinforcement structure for vehicle batteries is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a multi-angle reinforcement structure for vehicle batteries to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-angle reinforcement structure for vehicle batteries includes a honeycomb frame, which is composed of honeycomb panels and main rods, and a plurality of hydraulic damping column assemblies are arranged around the honeycomb frame.

[0008] The honeycomb panel consists of two symmetrically arranged cells, which are fixedly connected by several main rods. Several composite layers are fixedly connected between the two cells, and each composite layer has a heat-absorbing layer on its inner side. A cavity is formed between adjacent heat-absorbing layers for placing and fixing the battery.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0010] In one alternative embodiment: the hydraulic damping column assembly includes an oil tank, a hydraulic damping column is fixedly connected to the upper end of the oil tank, a piston chamber is provided inside the hydraulic damping column, a piston rod is slidably and sealed inside the piston chamber, a fixing plate is fixedly connected to the upper end of the piston rod, a sensor is provided on one side of the fixing plate, and a solenoid valve is provided through the oil tank on the side adjacent to the hydraulic damping column.

[0011] In one alternative: several connecting plates are fixedly connected around the honeycomb frame, and the connecting plates are respectively fixedly connected to adjacent oil tanks.

[0012] In one alternative: the sensor is a MEMS sensor used to monitor XYZ triaxial acceleration and vibration frequency in real time; a hydraulic actuator is installed in the oil tank and forms a closed-loop control system with the sensor.

[0013] In one alternative: the composite layer is a silicone-glass fiber composite layer, whose Shore hardness varies gradually from the cell side to the casing side.

[0014] In one alternative: the heat-absorbing layer is a paraffin / graphene composite.

[0015] In one alternative: a top cover and a bottom cover are slidably disposed at the upper and lower ends of the honeycomb frame, respectively, and a number of limiting blocks are disposed on the inner side of the top cover and the bottom cover.

[0016] In one alternative: the top cover and the bottom cover are provided with a number of fixing holes around their perimeter, and the top cover and the bottom cover are fixedly connected to the honeycomb frame by a number of bolts passing through the fixing holes.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model, through its honeycomb frame and three-dimensional honeycomb protective shell, effectively utilizes the non-orthogonal angle arrangement of the three-dimensional trusses to achieve multi-directional force decomposition. Simultaneously, the use of composite and heat-absorbing layers ensures both impact absorption and vibration suppression while maintaining battery heat dissipation through a rigid-flexible gradient buffer layer. Combined with the active-passive composite protection mechanism of the hydraulic damping column assembly, it effectively improves the protection of the vehicle battery, thereby enhancing the safety of vehicle battery use and driving safety.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-4 As shown, a multi-angle reinforcement structure for a vehicle battery includes a honeycomb frame 1, which is composed of a honeycomb panel 7 and a main rod 8, and a plurality of hydraulic damping column assemblies are arranged around the honeycomb frame 1.

[0026] The honeycomb panel 7 is provided in two symmetrical arrangements. The two honeycomb panels 7 are fixedly connected by a number of main rods 8. A number of composite layers 9 are fixedly connected between the two honeycomb panels 7. Each composite layer 9 has a heat-absorbing layer 10 on its inner side. The adjacent heat-absorbing layers 10 form a cavity for placing and fixing the storage battery.

[0027] In this embodiment, the honeycomb frame 1 is designed in a honeycomb form to improve the multi-directional force decomposition of the three-dimensional truss arranged at non-orthogonal angles. The composite layer 9 is added to achieve a rigid-flexible gradient buffer layer that takes into account both impact absorption and vibration suppression. Finally, the heat-absorbing layer 10 ensures heat dissipation.

[0028] In one embodiment, such as Figure 4 As shown, the hydraulic damping column assembly includes an oil tank 15, with a hydraulic damping column 11 fixedly connected to the upper end of the oil tank 15. The hydraulic damping column 11 has a piston chamber, and a piston column 12 is slidably and sealed within the piston chamber. A fixing plate 13 is fixedly connected to the upper end of the piston column 12. A sensor 14 is installed on one side of the fixing plate 13. A solenoid valve 16 is installed through the oil tank 15 on the side adjacent to the hydraulic damping column 11. The hydraulic damping column assembly achieves an active-passive composite protection mechanism. A MEMS sensor monitors the XYZ triaxial vibration frequency in real time. When the acceleration sensor detects an impact greater than 3g, the solenoid valve fully opens, and hydraulic oil flows rapidly through the damping orifice, improving the damping effect and thus enhancing the protection of the battery.

[0029] In one embodiment, such as Figure 4As shown, several connecting plates 4 are fixedly connected around the honeycomb frame 1. The connecting plates 4 are fixedly connected to the adjacent oil tanks 15 respectively, and are used to install hydraulic damping column assemblies.

[0030] In one embodiment, such as Figure 4 As shown, the sensor 14 is a MEMS sensor used to monitor the XYZ triaxial acceleration and vibration frequency in real time. The oil tank 15 is equipped with a hydraulic actuator, which forms a closed-loop control system with the sensor 14. The XYZ triaxial vibration frequency is monitored in real time by the MEMS sensor. When the acceleration sensor detects an impact greater than 3g, the solenoid valve is fully opened, and the hydraulic oil flows quickly through the damping orifice to improve the damping effect.

[0031] In one embodiment, such as Figure 3 As shown, the composite layer 9 is a silicone-glass fiber composite layer with a Shore hardness that gradually changes from 60HA on the cell side to 85HA on the shell side. The rigid-flexible gradient buffer layer takes into account both impact absorption and vibration suppression.

[0032] In one embodiment, such as Figure 3 As shown, the heat-absorbing layer 10 is a paraffin / graphene composite that undergoes an endothermic reaction in the range of 40-60℃.

[0033] In one embodiment, such as Figure 2 As shown, a top cover 2 and a bottom cover 3 are slidably disposed at the upper and lower ends of the honeycomb frame 1, respectively. Several limiting blocks 5 are disposed on the inner side of the top cover 2 and the bottom cover 3 to protect the battery.

[0034] In one embodiment, such as Figure 1 As shown, the top cover 2 and the bottom cover 3 are provided with a number of fixing holes 6 around their perimeter. The top cover 2 and the bottom cover 3 are fixedly connected to the honeycomb frame 1 by a number of bolts passing through the fixing holes 6, which are used to fix the top cover 2 and the bottom cover 3 to the honeycomb frame 1.

[0035] The above embodiments disclose a multi-angle reinforcement structure for vehicle batteries. A honeycomb frame 1, arranged in a honeycomb pattern, is used to improve the multi-directional force decomposition of the non-orthogonal angled three-dimensional truss. A composite layer 9 provides a rigid-flexible gradient buffer layer that balances impact absorption and vibration suppression. Finally, a heat-absorbing layer 10 ensures heat dissipation. An active-passive composite protection mechanism is achieved through a hydraulic damping column assembly. MEMS sensors monitor the XYZ triaxial vibration frequencies in real time. When the acceleration sensor detects an impact greater than 3g, the solenoid valve fully opens, and hydraulic oil flows rapidly through the damping orifice, improving the damping effect and thus enhancing battery protection.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
