Description

Technical Field

[0001] This application belongs to the field of battery tooling technology, specifically a battery vibration tooling. Background Technology

[0002] New energy technologies have begun to emerge in recent years, leading to the rise of numerous related industries and a continuous influx of people into the field. The main characteristics of new energy are energy conservation and environmental friendliness. Especially for electric vehicles, the battery pack is the heart of the entire energy system, and the design requirements for battery packs are becoming increasingly stringent. Not only is increased energy density required, but safety is also paramount. Therefore, before installing a battery pack in a vehicle, numerous experiments are necessary to verify its safety. These experiments typically include various tests such as airtightness, vibration, impact, charge / discharge, drop, rollover, collision, and compression tests to verify the battery pack's reliability.

[0003] However, most existing vibration fixtures are not securely clamped, have difficulty adjusting vibration parameters, and have low installation and positioning accuracy. Utility Model Content

[0004] The purpose of this application is to provide a battery vibration fixture in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: A battery vibration fixture includes a fixture base, a battery clamping assembly, a vibration driving assembly, a support and adjustment assembly, and a positioning and connecting assembly. The fixture base is a flat plate structure with arrayed mounting holes. The battery clamping assembly is disposed on the fixture base. The vibration driving assembly is connected to the battery clamping assembly. The support and adjustment assembly is disposed between the fixture base and the battery clamping assembly. The positioning and connecting assembly is used to position and connect each assembly to the fixture base. The fixture base provides a stable installation platform. The battery clamping assembly fixes the battery. The vibration driving assembly provides a vibration source. The support and adjustment assembly meets the height and angle adjustment requirements under different vibration conditions. The positioning and connecting assembly ensures the accuracy and stability of the installation of each assembly and provides basic structural support for subsequent vibration testing.

[0006] In a preferred embodiment, the battery clamping assembly includes a fixed clamping block and a movable clamping block. The fixed clamping block is fixed on the tooling base, and the movable clamping block is slidably connected to the fixed clamping block. The clamping surfaces of both the fixed and movable clamping blocks are provided with anti-slip buffer pads. This refines the structure of the battery clamping assembly. Through the cooperation of the fixed clamping block, the movable clamping block, and the clamping drive, batteries of different sizes can be clamped. The anti-slip buffer pads can prevent scratches on the battery surface during clamping, while also enhancing the friction between the clamping surface and the battery, preventing the battery from sliding during vibration, and ensuring the stability of the vibration test.

[0007] In a preferred embodiment, the vibration drive assembly includes a vibration motor, an eccentric wheel, and a transmission link. The vibration motor is fixed on the fixture base, and the eccentric wheel is mounted on the output shaft of the vibration motor. One end of the transmission link is hinged to the eccentric wheel. This optimizes the structure of the vibration drive assembly. By combining the vibration motor, eccentric wheel, and transmission link, the rotational motion of the motor is converted into the reciprocating vibration of the battery clamping assembly. Different vibration amplitudes and frequencies can be adjusted by selecting eccentric wheels with different eccentricities or by adjusting the speed of the vibration motor, thus meeting diverse battery vibration testing needs and improving the versatility of the fixture.

[0008] In a preferred embodiment, the support adjustment assembly includes a height adjustment column, an angle adjustment seat, and a locking member. One end of the height adjustment column is connected to the fixture base, and the other end is connected to the angle adjustment seat. The locking member is used to lock the rotation angle of the angle adjustment seat. This improved support adjustment assembly allows for the adjustment of the battery clamping assembly support height through the retractable height adjustment column. The cooperation between the angle adjustment seat and the locking member enables angle adjustment and locking, allowing the fixture to adapt to test scenarios with different vibration directions and height requirements, thus improving the flexibility and applicability of the fixture.

[0009] In a preferred embodiment, the positioning connection assembly includes a positioning block and connecting bolts. The mounting holes on the fixture base are positioning holes. The positioning block is inserted into the positioning holes and the positioning slots of each component to achieve positioning. The connecting bolts pass through the connecting holes of each component and are threadedly connected to the mounting holes of the fixture base to achieve fixation, thereby enhancing the positioning and fixing effect of the positioning connection assembly. The cooperation between the positioning block and the positioning holes and positioning slots ensures that the installation position of each component is accurate. The threaded connection of the connecting bolts provides a stable fixing force to prevent the components of the fixture from shifting during vibration, thus ensuring the accuracy of vibration testing.

[0010] In a preferred embodiment, multiple battery clamping components are provided, and each battery clamping component is evenly distributed along the length direction of the fixture base. Each battery clamping component can be independently driven for clamping and vibration, realizing simultaneous clamping and vibration testing of multiple batteries. Multiple independent battery clamping components can clamp batteries of different specifications according to test requirements, and can control the vibration state separately, improving the testing efficiency of the fixture and meeting the needs of batch battery vibration testing.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: In this application, the battery clamping assembly, vibration drive assembly, support adjustment assembly, and positioning connection assembly are designed collaboratively. The anti-slip buffer clamping structure of the battery clamping assembly ensures that the battery is fixed and stable. The eccentric wheel linkage transmission structure of the vibration drive assembly realizes efficient vibration conversion. The telescopic height adjustment column and angle adjustment seat of the support adjustment assembly cooperate to realize multi-dimensional adjustment. The positioning block and connecting bolt combination of the positioning connection assembly ensures that each component is installed accurately and firmly.

[0012] Beneficial effects: Compared with traditional vibration fixtures that suffer from unstable clamping, difficulty in adjusting vibration parameters, and low installation and positioning accuracy, this innovative structure can achieve stable clamping of the battery, preventing the battery from sliding during vibration and affecting the test results; by adjusting the support adjustment components, it can flexibly adapt to test scenarios with different vibration directions and height requirements, improving the applicability of the fixture; precise installation and positioning ensure high vibration transmission efficiency and stable vibration parameters, effectively improving the accuracy and reliability of battery vibration testing, while the collaborative work of multiple components also facilitates the assembly and disassembly of the fixture, improving operational convenience.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Example: Refer to Figure 1-3A battery vibration fixture includes a fixture base 1, a battery clamping assembly 2, a vibration drive assembly 3, a support and adjustment assembly 4, and a positioning and connecting assembly 5. The fixture base 1 is a flat plate structure with arrayed mounting holes. The battery clamping assembly 2 is mounted on the fixture base 1. The vibration drive assembly 3 is connected to the battery clamping assembly 2. The support and adjustment assembly 4 is positioned between the fixture base 1 and the battery clamping assembly 2. The positioning and connecting assembly 5 is used to position and connect each assembly to the fixture base 1. The fixture base provides a stable mounting platform, the battery clamping assembly fixes the battery, the vibration drive assembly provides a vibration source, the support and adjustment assembly meets the height and angle adjustment requirements under different vibration conditions, and the positioning and connecting assembly ensures the accuracy and stability of the installation of each assembly, providing basic structural support for subsequent vibration testing.

[0017] Reference Figure 1-3 The battery clamping assembly 2 includes a fixed clamping block 21 and a movable clamping block 22. The fixed clamping block 21 is fixed on the tooling base 1, and the movable clamping block 22 is slidably connected to the fixed clamping block 21. The clamping surfaces of both the fixed clamping block 21 and the movable clamping block 22 are provided with anti-slip buffer pads, which refine the structure of the battery clamping assembly. Through the cooperation of the fixed clamping block, the movable clamping block and the clamping drive, batteries of different sizes can be clamped. The anti-slip buffer pads can prevent scratches on the battery surface during clamping, while enhancing the friction between the clamping surface and the battery, preventing the battery from sliding during vibration, and ensuring the stability of vibration testing.

[0018] Reference Figure 1-4 The vibration drive assembly 3 includes a vibration motor 31, an eccentric wheel 32, and a transmission link 33. The vibration motor 31 is fixed on the tooling base 1, and the eccentric wheel 32 is mounted on the output shaft of the vibration motor 31. One end of the transmission link 33 is hinged to the eccentric wheel 32. The structure of the vibration drive assembly is optimized. By combining the vibration motor, the eccentric wheel, and the transmission link, the rotational motion of the motor is converted into the reciprocating vibration of the battery clamping assembly. Different vibration amplitudes and frequencies can be adjusted by selecting eccentric wheels with different eccentricities or adjusting the speed of the vibration motor, so as to meet the diverse battery vibration testing needs and improve the versatility of the tooling.

[0019] Reference Figure 1-3 The support adjustment assembly 4 includes a height adjustment column 41, an angle adjustment seat 42, and a locking member 43. One end of the height adjustment column 41 is connected to the fixture base 1, and the other end of the height adjustment column 41 is connected to the angle adjustment seat 42. The locking member 43 is used to lock the rotation angle of the angle adjustment seat 42. The improved support adjustment assembly realizes the adjustment of the support height of the battery clamping assembly through the telescopic height adjustment column. The cooperation between the angle adjustment seat and the locking member realizes the angle adjustment and locking, enabling the fixture to adapt to test scenarios with different vibration directions and height requirements, and improving the flexibility and applicability of the fixture.

[0020] Reference Figure 1-3 The positioning connection component 5 includes a positioning block 51 and a connecting bolt 52. The mounting holes on the fixture base 1 are positioning holes. The positioning block 51 is inserted into the positioning holes and the positioning slots of each component to achieve positioning. The connecting bolt 52 passes through the connecting holes of each component and is threadedly connected to the mounting holes of the fixture base 1 to achieve fixation, thereby enhancing the positioning and fixing effect of the positioning connection component. The cooperation between the positioning block and the positioning holes and positioning slots ensures that the installation position of each component is accurate. The threaded connection of the connecting bolt provides a stable fixing force to prevent the components of the fixture from shifting during vibration and to ensure the accuracy of vibration testing.

[0021] Reference Figure 1-3 Multiple battery clamping components 2 are provided, and each battery clamping component 2 is evenly distributed along the length direction of the fixture base 1. Each battery clamping component 2 can be independently clamped and vibrated, realizing simultaneous clamping and vibration testing of multiple batteries. Multiple independent battery clamping components can clamp batteries of different specifications according to test requirements, and can control the vibration state separately, improving the testing efficiency of the fixture and meeting the needs of batch battery vibration testing.

[0022] The implementation principle of a battery vibration fixture embodiment of this application is as follows: First, the vibration drive assembly 3 and the support adjustment assembly 4 are positioned and installed in their respective positions on the tooling base 1 using the positioning block 51 of the positioning connection assembly 5, and then fixed with the connecting bolts 52. Next, according to the specifications of the battery to be tested and the vibration test requirements, the extension and retraction of the height adjustment column 41 of the support adjustment assembly 4 is adjusted to adjust the support height of the battery clamping assembly 2. After rotating the angle adjustment seat 42 to a suitable angle, it is locked with the locking member 43. Then, the battery is placed between the fixed clamping block 21 and the movable clamping block 22 of the battery clamping assembly 2, and the clamping drive member 23 is activated to drive the movable clamping block 22 to move towards the fixed clamping block 21 until the battery is clamped. The anti-slip buffer pad can enhance the clamping stability and protect the battery. If multiple batteries are being tested, the above battery clamping steps are repeated, using multiple independent battery clamping assemblies 2 to clamp the batteries respectively.

[0023] Start the vibration motor 31 of the vibration drive assembly 3. The vibration motor 31 drives the eccentric wheel 32 to rotate. The eccentric wheel 32 converts the rotational motion into the reciprocating vibration of the battery clamping assembly 2 through the transmission link 33, thereby causing the battery clamped on the battery clamping assembly 2 to vibrate.

[0024] After the vibration test is completed, turn off the vibration drive assembly 3 and the vibration monitoring assembly 6, start the clamping drive 23 of the battery clamping assembly 2, move the movable clamping block 22 away from the fixed clamping block 21, and remove the battery.
