Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a shaft noise testing mechanism and a soundproof box. Background Technology

[0002] The conventional testing method involves manually flipping electronic products to test the durability of hinges in devices such as mobile phones and laptops. However, manual flipping tests lack supporting data; the number of flips, flip positions, flipping force, and flipping frequency cannot be statistically recorded. This results in inaccurate data for testing the durability of electronic product hinges, making it impossible to accurately evaluate their durability.

[0003] Existing flipping test equipment typically uses suction cups to fix electronic products. When the product is fixed with suction cups, it usually generates a lot of noise. However, since the testing device is quite sensitive to sound, the noise transmitted to the testing device can easily affect the test results. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a shaft noise testing mechanism that can reduce noise during the installation of the product under test.

[0005] This utility model also proposes a soundproof box having the above-mentioned shaft noise testing mechanism.

[0006] On one hand, the shaft noise testing mechanism according to an embodiment of the present invention includes: Base; A rotating assembly includes a rotating shaft and a first bracket, the rotating shaft being disposed on the first bracket and rotatably disposed on the base; The clamping assembly includes a second bracket, a rotating plate, and a clamping plate. The second bracket is disposed on the first bracket, the rotating plate is rotatably disposed on the second bracket, and the clamping plate is rotatably disposed on the second bracket. The rotating plate is provided with a guide groove, and the clamping plate is provided with a guide shaft. The guide shaft slides along the guide groove. The guide groove includes a sliding part and a locking part. The sliding part is arranged along an arc or a straight line, and the locking part is bent relative to the sliding part.

[0007] According to some embodiments of the present invention, the clamping assembly further includes an elastic element, one end of which is connected to the clamping plate and the other end of which is connected to the rotating plate. The elastic element is driven by the elastic element to make the clamping plate rotate in a direction away from the rotating plate.

[0008] According to some embodiments of the present invention, the clamping plate includes a pressing member and a connecting member. The pressing member is rotatably disposed on the first bracket, and one end of the connecting member is rotatably connected to the pressing member, while the other end is connected to a guide shaft.

[0009] According to some embodiments of the present invention, at least two clamping assemblies are provided.

[0010] According to some embodiments of the present invention, the clamping components are connected by connecting rods.

[0011] According to some embodiments of the present invention, the clamping plate is provided with a pressing block, which is made of an elastic material.

[0012] According to some embodiments of the present invention, the pressing block is provided with an inclined surface, which is used to partially abut the test product.

[0013] According to some embodiments of the present invention, the second bracket is provided with a pad, and the clamp is used to drive the product under test close to the pad.

[0014] According to some embodiments of the present invention, a self-locking component is also included, the self-locking component including a locking member, the rotating plate being provided with a locking groove, and the locking member being able to cooperate with the locking groove.

[0015] On the other hand, the soundproof box according to the present invention includes the shaft noise testing mechanism according to the above embodiment of the present invention.

[0016] The embodiments of this utility model have at least the following beneficial effects: The rotating assembly drives the product under test to rotate; the clamping mechanism can quickly clamp the product under test through the cooperation of the second bracket and the clamping plate. The clamping plate is driven to rotate by the rotating plate. Through the cooperation of the guide groove and the guide shaft, when the rotating plate rotates, the clamping plate rotates accordingly to achieve the purpose of clamping; the guide groove includes a sliding part and a locking part, which are relatively curved. When the guide shaft slides along the sliding part, the clamping plate can rotate without obstruction. When the guide shaft slides from the sliding part to the locking part, due to the influence of the bending area, a large external force is required to continue sliding. Similarly, when the guide shaft slides from the locking part to the sliding part, a large external force is also required to continue sliding, which plays a locking role on the clamping plate; through the guide groove of the mechanical structure, the jaws move along the guide rail. The jaws are connected by a crank-connecting rod mechanism. The pure mechanical structure operation produces less noise and will not interfere with the testing device.

[0027] On the one hand, refer to Figures 1-4 The shaft noise testing mechanism according to an embodiment of the present invention includes: Base 100; The rotating assembly 200 includes a rotating shaft 210 and a first bracket 220. The rotating shaft 210 is disposed on the first bracket 220 and is rotatably disposed on the base 100. The clamping assembly 300 includes a second bracket 310, a rotating plate 320, and a clamping plate 330. The second bracket 310 is disposed on the first bracket 220, the rotating plate 320 is rotatably disposed on the second bracket 310, and the clamping plate 330 is rotatably disposed on the second bracket 310. The rotating plate 320 is provided with a guide groove 311, and the clamping plate 330 is provided with a guide shaft. The guide shaft slides along the guide groove 311. The guide groove 311 includes a sliding part 311a and a locking part 311b. The sliding part 311a is arranged along an arc or a straight line, and the locking part 311b is bent relative to the sliding part 311a.

[0028] According to the embodiments of this utility model, the following effects can be achieved by the following configuration: the rotating component 200 can drive the product under test to rotate; the clamping mechanism can quickly clamp the product under test through the cooperation of the second bracket 310 and the clamping plate 330; the clamping plate 330 is driven to rotate by the rotating plate 320; through the cooperation of the guide groove 311 and the guide shaft, when the rotating plate 320 rotates, the clamping plate 330 rotates accordingly, achieving the purpose of clamping; the guide groove 311 includes a sliding part 311a and a locking part 311b; the sliding part is arranged in a continuous structure of straight line or arc; the guide shaft slides along the sliding part without jamming; and the sliding part 311a... The guide shaft is bent relative to the locking part 311b. When the guide shaft slides along the sliding part 311a, the clamping plate 330 can rotate without obstruction. When the guide shaft slides from the sliding part 311a to the locking part 311b, due to the influence of the bending area, a large external force is required to continue sliding. Similarly, when the guide shaft slides from the locking part 311b to the sliding part 311a, a large external force is also required to continue sliding, which locks the clamping plate 330. The gripper moves along the guide rail through the guide groove 311 of the mechanical structure. The gripper is connected by a crank-connecting rod 350 mechanism. The pure mechanical structure operation produces less noise and will not interfere with the detection device.

[0029] It is understandable that the external force required for the sliding part 311a to slide to the locking part 311b is greater than the inertial force that drives the component under test to rotate when the rotating component 200 is working.

[0030] In some embodiments, the clamping assembly 300 further includes an elastic element 340, one end of which is connected to the clamping plate 330 and the other end to the rotating plate 320. The elastic element 340 is driven by the elastic element to rotate the clamping plate 330 in a direction away from the rotating plate 320. When the guide shaft slides to the sliding part 311a, the clamping plate 330 is unlocked, and the elastic element 340 can drive the clamping plate 330 to move away from the rotating plate 320, allowing the guide shaft to slide along the sliding groove.

[0031] In some embodiments, the clamping plate 330 includes a pressing member 331 and a connecting member 332. The pressing member 331 is rotatably disposed on the first bracket 220. One end of the connecting member 332 is rotatably connected to the pressing member 331, and the other end is connected to a guide shaft. The second bracket 310, the rotating plate 320, the connecting member 332, and the pressing member 331 are sequentially connected to form a linkage 350 mechanism. When the rotating plate 320 is manually driven to rotate in the second bracket 310, the pressing member 331 can rotate, so that the pressing member 331 can clamp the product to be tested.

[0032] In some embodiments, at least two clamping assemblies 300 are provided. Multiple clamping assemblies 300 facilitate more stable clamping of the product under test.

[0033] In some embodiments, the clamping assemblies 300 are connected by a link 350. A single link 350 can simultaneously drive multiple clamping assemblies 300 to work together, facilitating use.

[0034] In some embodiments, the clamping plate 330 is provided with a pressing block 333, which is made of an elastic material. The pressing block 333, made of elastic material, clamps the product without crushing it, thus reducing damage to the product.

[0035] In some embodiments, the pressing block 333 is provided with an inclined surface 334, which is used to partially abut the product to be tested. The inclined surface 334 can reduce the contact area between the pressing block 333 and the product. The contact surface between the pressing block 333 and the product to be tested is mainly made of hard material and does not contact the screen, thus preventing damage to the screen.

[0036] In some embodiments, the second support 310 is provided with a pad, and the clamping plate 330 is used to drive the product under test close to the pad. The pad is used to protect the product under test and provides support.

[0037] In some embodiments, the gasket has multiple support pads.

[0038] In some embodiments, a self-locking assembly 400 is further included. The self-locking assembly 400 includes a locking member 410, and the rotating plate 320 is provided with a locking groove 420. The locking member 410 can cooperate with the locking groove 420. After the guide shaft slides from the sliding part 311a to the locking part 311b, the guide shaft continues to slide along the locking part 311b. When the guide shaft slides to the correct position, the locking member 410 can cooperate with the locking groove 420, so that the rotating plate 320 and the second bracket 310 are relatively fixed, thereby improving stability.

[0039] Furthermore, the locking element 410 is provided with a conical or spherical insert that can be inserted into the locking groove 420. When the rotating plate 320 rotates, the insert can slide along the groove surface of the locking groove 420, and the locking mechanism of the rotating plate 320 can be separated from the insert by external force.

[0040] Furthermore, the locking member 410 is provided with a spring, which is driven by elastic force to move the locking member 410 in a direction close to the rotating plate 320.

[0041] The above are merely preferred embodiments of this utility model. This utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model, as long as they achieve the same technical effect, should be included within the scope of protection disclosed in this utility model. Within the scope of protection of this utility model, the technical solutions and / or implementation methods can have various modifications and variations.
