Description

Technical Field

[0001] The utility model relates to the field of anti - shake testing, in particular to a novel double - axis high - frequency jitter device. Background Technique

[0002] The anti - shake testing of AR anti - shake telescopes and anti - shake cameras is an important part of evaluating their anti - shake performance. There are currently two types of anti - shake testing equipment. One is a three - axis jitter testing platform, which is complex to operate, expensive, and has a high maintenance cost. The second is a single - axis jitter testing platform, which can only test the anti - shake performance in a single direction and cannot test the anti - shake performance of the product completely. A double - axis jitter testing platform is a device used to simulate and test the jitter or vibration of a device in two - axis directions.

[0003] After retrieval, the publication number CN207894581U discloses a double - axis high - frequency jitter device, which includes a base. A jitter platform is arranged on the base and can swing relative to the base in a horizontal plane and a vertical plane. A double - axis transmission device is also arranged on the base. The double - axis transmission device includes a first transmission shaft arranged horizontally on the base. A rotating platform is arranged on the first transmission shaft. A first driving device for driving the rotating platform to rotate in the vertical plane is arranged on the base. The double - axis transmission device further includes a second transmission shaft arranged vertically on the rotating platform. The jitter platform is connected to the second transmission shaft. A second driving device for driving the jitter platform to rotate relative to the rotating platform in the horizontal plane is arranged on the rotating platform.

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figures 1-5, a new type of dual-axis high-frequency jitter device, comprising: a housing 1, the top of the housing 1 is provided with an opening. The housing 1 serves as the support and protection structure of the entire device. The opening design at its top facilitates the installation of the horizontal jitter platform 2 and the placement of test products. The sealing property of the housing 1 helps reduce the leakage of vibration noise and protects the internal mechanical structure from external environmental interference; a horizontal jitter platform 2, arranged above the housing 1, is configured to jitter in the horizontal direction, for placing test products and driving the test products to jitter horizontally; a vertical jitter platform 3, installed inside the housing 1, the horizontal jitter platform 2 is connected to the vertical jitter platform 3, and the vertical jitter platform 3 is configured to jitter in the vertical direction, for driving the horizontal jitter platform 2 and the test products to jitter vertically; the vertical jitter platform 3 includes a mounting plate 301 and a vertical vibration motor 302. The mounting plate 301 is installed at the bottom of the vertical jitter platform 3, and the vertical vibration motor 302 is installed on the mounting plate 301. The vertical vibration motor 302 is used to provide a vibration source, and the vertical vibration motor 302 is configured to be rotatable on the mounting plate 301 for adjusting the jitter direction. When the vertical vibration motor 302 rotates 30°, the vertical vibration motor 302 can jitter the vertical jitter platform 3 in an obliquely upward direction.

[0028] Refer to Figure 2 and Figure 3 , the horizontal jitter platform 2 includes: a connecting plate 201, installed at the bottom of the horizontal jitter platform 2. The connecting plate 201 serves as the connection bridge between the horizontal jitter platform 2 and the vertical jitter platform 3 to ensure the effective transmission of vibration energy; a horizontal vibration motor 202, installed on the connecting plate 201, for providing a vibration source for the horizontal jitter platform 2 and the connecting plate 201. The horizontal vibration motor 202 provides a stable vibration source for the horizontal jitter platform 2 to achieve high-frequency jitter of the test products in the horizontal direction and simulate the horizontal vibration environment in the real use scenario; two vertical plates 203, installed on the vertical jitter platform 3, and the two vertical plates 203 are respectively arranged on both sides of the connecting plate 201; two first elastic members 204, one end is connected to the vertical plate 203 and the other end is connected to the connecting plate 201. The first elastic members 204 are used to provide vibration power for the connecting plate 201. Through elastic connection, the dynamic response ability of the horizontal jitter platform 2 is increased, making the jitter more uniform and natural, and at the same time reducing the direct impact on the vertical jitter platform 3.

[0029] Refer to Figure 3 , Figure 4 and Figure 5, the vertical shaking platform 3 further includes: an adjusting plate 305, mounted on the mounting plate 301, and the vertical vibration motor 302 is mounted on the adjusting plate 305. As the main vibration source in the vertical direction, it can drive the entire vertical shaking platform 3, the horizontal shaking platform 2 thereon, and the test product to perform vertical shaking, simulating vibration environments in different directions; two fixing plates 303, mounted on the inner wall of the housing 1, arranged symmetrically, and the two fixing plates 303 are located below the vertical shaking platform 3; two second elastic members 304, one end connected to the fixing plate 303 and the other end connected to the bottom of the vertical shaking platform 3, and the second elastic members 304 are used to provide vibration power for the vertical shaking platform 3; a plurality of threaded grooves 306, opened on one side of the mounting plate 301. Through elastic support, the dynamic response ability of the vertical shaking platform 3 is increased, making the shaking more uniform and natural, and improving the stability and efficiency of vibration; two bolts 307, mounted on the adjusting plate 305, and the bolts 307 are connected to the threaded grooves 306, used to fix the position of the adjusting plate 305 on the mounting plate 301. The bolts 307 achieve precise fixation of the adjusting plate 305 on the mounting plate 301, ensuring the stability of the vibration motor after adjusting the position and preventing loosening or deviation during vibration.

[0030] Referring to Figure 2 and Figure 3 , a controller 4, mounted in the housing 1; a bottom plate 5, mounted at the bottom of the housing 1. As the control center of the entire device, the controller 4 can receive and process instructions from the user or external sensors, and precisely control the operating parameters (such as frequency, amplitude, etc.) of the horizontal vibration motor 202 and the vertical vibration motor 302, achieving precise control of the dual-axis shaking.

[0031] Referring to Figure 1 , the housing 1 includes: a plurality of floor feet 101, mounted at the bottom of the housing 1, and the bottom ends of the floor feet 101 are connected to the bottom plate 5. The floor feet 101 firmly fix the housing 1 on the bottom plate 5, preventing the movement or shaking of the housing 1 during vibration; a switch button 102, mounted on the surface of the housing 1; a vertical shaking frequency converter 103, mounted on the surface of the housing 1, and the vertical shaking frequency converter 103 is connected to the controller 4; a vertical shaking frequency conversion switch 104, mounted on the surface of the housing 1, and the vertical shaking frequency conversion switch 104 is connected to the controller 4; a vertical shaking frequency conversion adjustment knob 105, mounted on the surface of the housing 1, and the vertical shaking frequency conversion adjustment knob 105 is connected to the controller 4; a horizontal shaking frequency converter 108, mounted on the surface of the housing 1, and the horizontal shaking frequency converter 108 is connected to the controller 4; a horizontal shaking frequency conversion switch 107, mounted on the surface of the housing 1, and the horizontal shaking frequency conversion switch 107 is connected to the controller 4; a horizontal shaking frequency conversion adjustment knob 106, mounted on the surface of the housing 1, and the horizontal shaking frequency conversion adjustment knob 106 is connected to the controller 4.

[0032] During use, place the test product on the horizontal shaking platform 2 to ensure that the product is stable and will not slip due to shaking. Turn on the switch button 102 on the surface of the housing 1 to start the device. Use the vertical shaking frequency converter 103 and the horizontal shaking frequency converter 108 to view the current vibration frequencies in the vertical and horizontal directions respectively. Adjust the required vibration frequencies according to the test requirements through the vertical shaking frequency adjustment knob 105 and the horizontal shaking frequency adjustment knob 106. Press the vertical shaking frequency switch 104 and the horizontal shaking frequency switch 107 to confirm that the vibration parameters are set and effective. The vertical vibration motor 302 starts to work and generates vertical vibration according to the set vibration parameters. The vibration generated by the vertical vibration motor 302 is transmitted to the vertical shaking platform 3 through the mounting plate 301. The second elastic member 304 provides elastic support at the bottom of the vertical shaking platform 3 to increase the dynamic response ability and uniformity of the shaking. If the shaking direction needs to be adjusted, remove the bolt 307 from the original thread groove 306, and the position of the vertical vibration motor 302 on the mounting plate 301 can be rotated, for example, rotated by 30°, to achieve shaking in the obliquely upward direction. Then install the bolt 307 into another thread groove 306 to fix the position of the adjusting plate 305 after rotation. The horizontal vibration motor 202 starts to work to provide a vibration source for the horizontal shaking platform 2 and the connecting plate 201. The connecting plate 201 serves as a bridge to transmit the vibration energy to the horizontal shaking platform 2, driving the test product to perform high-frequency shaking in the horizontal direction. The first elastic member 204 helps to achieve more uniform and natural shaking. When the vibration motors in both the vertical and horizontal directions work simultaneously, the test product will be subjected to the action of biaxial high-frequency shaking. The controller 4, as the control center, continuously monitors and adjusts the operating parameters of the vibration motors to ensure the precise control and stability of the biaxial shaking. The operator can monitor and adjust the vibration parameters in real time through the frequency converters and adjustment knobs on the surface of the housing 1.

[0033] In summary, compared with the prior art, the following beneficial effects are achieved:

[0034] This solution not only realizes the basic vibration control in the horizontal and vertical directions, but also through the rotational design of the vertical vibration motor 302 on the mounting plate 301, enables the shaking platform to generate precise shaking in the obliquely upward or other non-vertical and non-horizontal directions. This multi-dimensional vibration control ability greatly expands the test range and adaptability of the device, meeting the requirements of different test scenarios for complex vibration environments.

[0035] By rotating the vertical vibration motor 302, users can flexibly adjust the spatial attitude of the shaking platform to achieve precise control of the vibration direction. This design enables the device to simulate more diverse vibration environments, improving the accuracy and authenticity of the test.

[0036] The first elastic member 204 and the second elastic member 304 not only provide vibration power for the platform, but also increase the dynamic response ability of the platform, making the jitter more uniform and natural. As the control center of the entire device, the controller 4 can receive and process instructions from users or external sensors, and precisely control the operating parameters of the horizontal vibration motor 202 and the vertical vibration motor 302.
