Description

Technical Field

[0001] This invention relates to the field of solid-state battery technology, and in particular to a vibration testing device for solid-state batteries used in low-altitude economic applications. Background Technology

[0002] As an emerging economic form, the low-altitude economy is gradually becoming a new driving force for industrial upgrading and economic development. It is a comprehensive economic activity based on low-altitude airspace, led by the general aviation industry, and encompassing multiple fields such as low-altitude flight, air tourism, air logistics, and emergency rescue. With continuous technological advancements and the gradual liberalization of policies, the low-altitude economy has ushered in unprecedented development opportunities. The application of various low-altitude aircraft, such as drones and light aircraft, is becoming increasingly widespread, leading to a growing demand for related supporting industries. Among these, solid-state batteries, as the core power source for low-altitude aircraft, directly affect the safe operation and operational efficiency of the aircraft. Therefore, comprehensive and rigorous testing of solid-state batteries is particularly crucial.

[0003] In the low-altitude economy, solid-state batteries are inevitably subjected to various vibrations during flight, which may originate from takeoff, landing, flight attitude adjustments, and external environmental factors. To ensure that solid-state batteries can function properly under complex vibration environments and avoid safety hazards such as performance degradation, short circuits, or even fire and explosion, specialized vibration testing is required. A vibration testing device for solid-state batteries in the low-altitude economy has emerged to address this need. It can simulate various vibration conditions that may be encountered during actual flight, accurately testing and evaluating solid-state batteries. This provides crucial data support for the research, development, production, and application of solid-state batteries, thereby ensuring the safe operation of low-altitude aircraft and promoting the healthy development of the low-altitude economy.

[0004] However, existing solid-state battery vibration testing equipment has significant shortcomings in terms of automation. Many testing devices still require a large amount of manual operation, from sample installation and fixation, setting test parameters, monitoring the testing process, and recording and analyzing test results, all of which require the full participation of testing personnel. This not only increases the workload and time cost of testing, but also easily leads to errors and inaccuracies in test results due to human factors. Summary of the Invention

[0005] In order to at least solve one of the above-mentioned technical problems, the present invention aims to provide a vibration testing device for low-altitude economic solid-state batteries, thereby improving the degree of automation and production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vibration testing device for low-altitude economic solid-state batteries includes a workbench with a vibration generating mechanism. A battery clamping mechanism is fixedly mounted on top of the vibration generating mechanism, and a battery loading / unloading mechanism is mounted above the workbench via a mounting bracket. The vibration generating mechanism includes a receiving groove on the workbench, with a movable block connected to the top of the receiving groove via an elastic connecting ring. The bottom of the movable block has a movable cavity, and a ball bearing is evenly rotatably connected to the bottom edge of the movable block. The ball bearing rolls in contact with the bottom of the receiving groove. A servo motor is installed inside the receiving groove, and a cam is fixedly connected to the output shaft of the servo motor. The tip of the cam slides against the inner wall of the movable cavity. The battery loading / unloading mechanism includes a translation component connected to the top of the mounting bracket. A lifting cylinder is fixedly connected to the bottom movable part of the translation component, and a mechanical gripper is fixedly connected to the bottom movable part of the lifting cylinder.

[0008] Preferably, the battery clamping mechanism includes multiple clamping components, which are evenly arranged in a ring above the movable block. Each clamping component includes a clamping cylinder, and a clamping plate is fixedly connected to the movable part of the clamping cylinder facing the center of the movable block.

[0009] Preferably, the working surface of the clamping plate is coated with a first anti-slip coating, and the movable block is coated with a second anti-slip coating.

[0010] Preferably, the translation component is an electric slide.

[0011] Preferably, the elastic connecting ring is a ring structure made of rubber, and the groove wall of the receiving groove is provided with heat dissipation holes.

[0012] Preferably, the mounting frame is a gantry structure, and the crossbeam of the gantry is provided with reinforcing ribs.

[0013] The present invention has the following beneficial effects:

[0014] I. Improved Automation and Production Efficiency: The low-altitude economic solid-state battery vibration testing device of this invention significantly improves automation through ingenious structural design. The translation component (such as an electric slide) in the battery loading and unloading mechanism works in conjunction with the lifting cylinder and mechanical grippers to automatically complete the loading and unloading of solid-state batteries, eliminating the need for manual installation and removal and reducing human intervention. Simultaneously, the vibration generating mechanism, driven by a servo motor, rotates a cam, causing a moving block to vibrate. The entire vibration process can be precisely controlled, eliminating the need for frequent manual adjustments to vibration parameters. This highly automated design not only reduces the workload of testing personnel and saves time, but also avoids errors and inaccuracies in test results caused by human factors, thereby improving production efficiency.

[0015] Second, enhanced testing accuracy: In the vibration generating mechanism, the ball bearings connected to the bottom edge of the movable block rotate evenly and roll in contact with the bottom of the receiving groove. This design allows the movable block to move more smoothly during vibration, reducing friction and resistance, thus more accurately simulating the vibration experienced by solid-state batteries during actual flight. Simultaneously, the first anti-slip coating on the working surface of the clamping plate and the second anti-slip coating on the movable block effectively prevent the battery from sliding or shifting during vibration testing, ensuring the stability and accuracy of the test and providing more reliable data support for the research, development, production, and application of solid-state batteries.

[0016] Third, ensuring equipment stability and durability; the elastic connecting ring adopts a ring structure made of rubber, which has good elasticity and cushioning performance. It can absorb some energy during vibration, reducing the impact of vibration on the worktable and other components, thereby ensuring the stability of the entire testing device. In addition, the heat dissipation holes on the wall of the receiving tank help the servo motor dissipate heat in a timely manner during long-term operation, preventing the motor from being damaged due to overheating, extending the service life of the equipment, and improving its durability.

[0017] IV. Optimized Structural Strength and Space Utilization: The mounting frame adopts a gantry structure with reinforcing ribs on the crossbeams, enhancing its structural strength and enabling it to better support the weight of the battery loading / unloading mechanism and other components, thus ensuring the stability of the testing device during operation. Simultaneously, this structural design makes efficient use of space, resulting in a more compact layout of components, reducing the overall footprint of the device, and improving space utilization.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 2 As shown, a vibration testing device for solid-state batteries used in low-altitude economic applications includes a workbench 1, on which a vibration generating mechanism is installed. A battery clamping mechanism is fixedly installed on the top of the vibration generating mechanism. A battery pick-and-place mechanism is installed above the workbench 1 via a mounting frame 2. The vibration generating mechanism includes a receiving groove 301 on the workbench 1. A movable block 303 is connected to the top of the receiving groove 301 via an elastic connecting ring 302. A movable cavity is opened at the bottom of the movable block 303. A ball bearing 304 is evenly rotatably connected to the bottom edge of the movable block 303. The ball bearing 304 rolls in contact with the bottom of the receiving groove 301. A servo motor 351 is installed inside the receiving groove 301. A cam 352 is fixedly connected to the output shaft of the servo motor 351. The tip of the cam 352 slides against the inner wall of the movable cavity. The battery pick-and-place mechanism includes a translation component 401 connected to the top of the mounting frame 2. A lifting cylinder 402 is fixedly connected to the bottom movable part of the translation component 401. A mechanical gripper 403 is fixedly connected to the bottom movable part of the lifting cylinder 402.

[0024] like Figures 1 to 2 As shown, a servo motor 351 is installed in the receiving groove 301 of the worktable 1. After the servo motor 351 is started, its output shaft drives the fixedly connected cam 352 to rotate. Since the tip of the cam 352 slides against the inner wall of the movable cavity at the bottom of the movable block 303, the rotation of the cam 352 will push the movable block 303 to reciprocate in the vertical direction. The ball bearings 304, which are uniformly connected to the bottom edge of the movable block 303, roll into contact with the bottom of the receiving groove 301. This design reduces the friction between the movable block 303 and the receiving groove 301, allowing the movable block 303 to move more smoothly, while ensuring the stability of the movable block 303's movement. The movable block 303 is connected to the top of the receiving groove 301 through an elastic connecting ring 302. The elastic connecting ring 302 can further buffer and adjust the movement of the movable block 303, making its vibration more consistent with the vibration conditions experienced by the solid-state battery during actual flight. The battery clamping mechanism is fixedly installed on the top of the movable block 303 of the vibration generating mechanism. When testing solid-state batteries, the battery is placed on the movable block 303. The battery clamping mechanism clamps and fixes the battery through its structure, ensuring that the battery will not shift or fall off during vibration, thus guaranteeing the accuracy and safety of the test.

[0025] The battery pick-and-place mechanism is mounted above the workbench 1 via mounting bracket 2. The translation component 401 can move its bottom movable part horizontally, and the lifting cylinder 402, fixed to the bottom movable part of the translation component 401, can move its bottom movable part vertically. The mechanical gripper 403 is fixed to the bottom movable part of the lifting cylinder 402. When a battery needs to be picked up, the translation component 401 and the lifting cylinder 402 work together to move the mechanical gripper 403 to the location of the battery, and the mechanical gripper 403 picks up the battery. When a battery needs to be placed, the translation component 401 and the lifting cylinder 402 similarly move the mechanical gripper 403 to the designated position, and the mechanical gripper 403 releases the battery, completing the battery pick-and-place operation.

[0026] Based on the above operating principle, various vibrations experienced by solid-state batteries during actual flight of low-altitude aircraft can be accurately simulated. The vibration frequency and amplitude generated by the servo motor 351 driving the cam 352 can be precisely adjusted by controlling the speed and rotation angle of the servo motor 351 to meet different testing requirements. The design of the elastic connecting ring 302 and the ball bearing 304 makes the vibration more stable and realistic, reducing the interference of external factors. The battery clamping mechanism ensures the stability of the battery during vibration testing, avoiding test errors caused by battery movement. The automated operation of the battery loading and unloading mechanism improves testing efficiency, reduces manual intervention, and minimizes the impact of human factors on test results.

[0027] like Figures 1 to 2 As shown, this battery clamping mechanism primarily utilizes multiple evenly distributed ring-shaped clamping components to securely hold the solid-state battery. Specifically, the clamping cylinder 501 in each clamping component is its core power unit. When clamping the solid-state battery is required, the clamping cylinder 501 is activated, and its movable part moves linearly towards the center of the movable block 303. Since the clamping plate 502 is fixedly connected to the movable part of the clamping cylinder 501, the clamping plate 502 moves towards the center along with the movable part. Multiple clamping components work simultaneously, and multiple clamping plates 502 converge towards the center from different directions, ultimately clamping the solid-state battery placed on the movable block 303 tightly. The first anti-slip coating applied to the working surface of the clamping plate 502 and the second anti-slip coating applied to the movable block 303 play a crucial anti-slip role. During the clamping process, the first anti-slip coating increases the friction between the clamping plate 502 and the surface of the solid-state battery, preventing the battery from sliding relative to the clamping plate 502 during vibration testing; the second anti-slip coating increases the friction between the bottom of the solid-state battery and the surface of the movable block 303, preventing the battery from shifting on the movable block 303, thereby ensuring that the battery can maintain a relatively stable position during vibration testing.

[0028] This design reliably secures the solid-state battery to the movable block 303, providing stable testing conditions for subsequent vibration tests. The circular, evenly distributed arrangement of multiple clamping components ensures a more uniform clamping force on the battery, preventing uneven force distribution that could lead to excessive or insufficient force in certain areas, effectively protecting the battery's structural integrity. The first and second anti-slip coatings further enhance clamping stability, ensuring the battery does not slip or shift even under high-amplitude, high-frequency vibrations, guaranteeing the accuracy and reliability of the test data.

[0029] like Figures 1 to 2 As shown, the electric slide table mainly consists of a motor, lead screw, nut, and guide rail. After the motor starts, its output shaft drives the lead screw to rotate. Since the nut and lead screw form a helical transmission pair, and the nut is connected to the slider of the electric slide table, while the slider can slide on the guide rail, according to the principle of helical transmission, the rotational motion of the lead screw is converted into the linear motion of the nut, which in turn drives the slider to move linearly along the guide rail. In this device, the electric slide table serves as a translation component 401, and its slider is connected to the lifting cylinder 402. By controlling the forward and reverse rotation of the motor, the slider can move bidirectionally in the horizontal direction, thereby driving the lifting cylinder 402 and the mechanical gripper 403 to move in the horizontal direction, completing the battery pick-up and drop operation between different positions. The elastic connecting ring 302 is made of rubber and is connected between the movable block 303 and the top of the receiving groove 301. Rubber has good elastic properties. When the servo motor 351 in the vibration generating mechanism drives the cam 352 to rotate, causing the movable block 303 to vibrate up and down, the elastic connecting ring 302 will undergo elastic deformation. On the one hand, it can buffer the impact force generated when the movable block 303 vibrates, reducing the impact of vibration on the worktable 1 and other components; on the other hand, its elastic deformation capability can adapt to the vibration of the movable block 303 at different amplitudes, ensuring that the movable block 303 can move freely up and down, while maintaining the relative positional relationship between the movable block 303 and the receiving groove 301, making the vibration more stable and reliable.

[0030] The servo motor 351 generates heat during operation. If this heat cannot be dissipated in time, the motor temperature will rise, affecting its performance and lifespan. Heat dissipation holes 306 are provided on the wall of the receiving slot 301. Utilizing the principle of air convection, when the motor is running, the surrounding air is heated and rises, while cool air enters the receiving slot 301 through the heat dissipation holes 306, forming an air circulation that carries away the heat generated by the motor, thus achieving heat dissipation and ensuring that the servo motor 351 operates in a suitable temperature environment. The mounting bracket 2 adopts a gantry structure, which has high strength and stability, capable of supporting the weight of the battery loading / unloading mechanism and the battery. Reinforcing ribs are provided on the crossbeam of the gantry, increasing the crossbeam's moment of inertia and improving its bending resistance. During the operation of the battery loading / unloading mechanism, certain forces and torques are generated. The reinforcing ribs effectively disperse these forces and torques, reducing crossbeam deformation and ensuring the stability and reliability of the entire mounting bracket 2 structure. This ensures that the battery loading / unloading mechanism can complete the battery loading / unloading operation normally and accurately.

[0031] Through the working principles of the aforementioned components, the device achieves stable and reliable operation. The electric slide provides precise horizontal movement for the battery pick-and-place mechanism, enabling the mechanical gripper 403 to accurately reach the designated position for battery pick-and-place. The elastic connecting ring 302 effectively buffers vibration, ensuring the stability and accuracy of vibration testing while reducing damage to other components. The heat dissipation holes 306 in the receiving slot 301 promptly dissipate the heat generated by the servo motor 351, extending the motor's service life. The gantry structure mounting bracket 2 and reinforcing ribs provide solid support for the entire battery pick-and-place mechanism, ensuring its stability and reliability during operation and improving the performance and testing quality of the entire low-altitude economic solid-state battery vibration testing device.

[0032] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
