Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to the field of a shaft durability testing machine. Background Technology

[0002] With the advancement and development of technology, electronic products have become indispensable in people's lives, mainly including smartphones, computers, tablets, etc. Some electronic products, such as laptops, require frequent folding during daily use, making durability testing of the hinges of these products particularly important. For example, patent application number CN202311373524.0, entitled "A Durability Testing Device for Flip Tablets," discloses a device that uses a limiting component. When the inclined support moves to contact the limiting component, the inclined support is stopped from further flipping by the limiting component. The cover continues to flip under inertia and gradually stops under the damping action of the damping hinge. This inertial movement method better simulates the flipping process. After stopping, the cylinder returns to its original position, and the limiting block can then drive the cover back to its original position, facilitating the smooth progress of the next flipping cycle.

[0039] Specifically, such as Figure 4As shown, at least one set of fixture assembly 3 is provided. In this embodiment, one to three sets of fixture assemblies are provided. With this configuration, the shaft durability testing machine can test one to three products simultaneously, effectively improving testing efficiency. Of course, it is not limited to this; other methods can be used to improve testing efficiency.

The rocker arm clamp assembly 31 is connected to the motor 2, the rocker arm adjustment assembly 4 is connected to the rocker arm clamp 31, and the fixed-side clamp assembly 32 is fixedly connected to the main body 1. The rocker arm clamp 31 is positioned between the fixed-side clamp assembly 32 and the main body 1. In this embodiment, the rocker arm adjustment assembly is adjusted according to the product size, the rocker arm clamp clamps one end of the product, and the fixed-side clamp assembly clamps the other end of the product. The motor rotates, causing the rocker arm clamp to rotate, while the fixed-side clamp assembly remains stationary, enabling repeated folding of the product to complete the durability test of the product's rotating shaft. Of course, this is not limited to this; other fixtures or fixture assemblies that perform rotating shaft durability tests on products can be used.

[0041] Specifically, the rocker arm clamp 31 includes a rocker arm 311 and an upper clamp 312, with the rocker arm 311 connected to the upper clamp 312 via a rocker arm adjustment assembly 4. In this embodiment, one end of the product is clamped and fixed by the upper clamp, and the motor drives the rocker arm to rotate, causing the upper clamp to start rotating. Of course, the above structure is not limited to this and can be other structures that perform the same function.

[0042] Specifically, the rocker arm adjustment assembly 4 includes an adjustment groove 41, an adjustment block 42, and an upper clamp fixing part 43. The adjustment groove 41 is disposed on the rocker arm 311, the adjustment block 42 is slidably connected to the rocker arm 311 through the adjustment groove 41, the upper clamp fixing part 43 is fixedly connected to the adjustment block 42, and the upper clamp 312 is connected to the upper clamp fixing part 43. In this embodiment, the height adjustment of the adjustment block, the upper clamp fixing part, and the upper clamp on the rocker arm is achieved by the adjustment block within the rocker arm groove. Of course, the above structure is not limited to this; other structures can be used to achieve height adjustment of the upper clamp on the rocker arm.

[0043] Specifically, the upper clamp fixing part 43 is provided with an upper clamp groove 44 for adjusting the upper clamp 312. In this embodiment, the upper clamp is adjusted left and right on the upper clamp fixing part through the upper clamp groove. Of course, the above structure is not limited to this, and other structures can be used to achieve left and right adjustment of the upper clamp on the upper clamp fixing part.

[0044] Specifically, the lateral clamp assembly 32 includes a lower clamp fixing part 321, a lower clamp 322, and a lower clamp fastener 323. At least two lower clamp fixing parts 321 are provided, and each lower clamp fixing part 321 is fixedly connected to the main body 1. The lower clamp fixing parts 321 are located at both ends of the lower clamp 322, which is fixedly connected to the main body 1 via the lower clamp fixing parts 321. A rocker arm 311 is located between the lower clamp fixing parts 321 and the main body 1, and the lower clamp fastener 323 is located on the lower clamp 322. In this embodiment, during testing, one end of the product is placed on the lower clamp, and the product is clamped by the lower clamp fastener. During the test, the lateral clamp assembly remains stationary. However, the above structure is not limited to this and can be other structures that perform the same function.

[0045] Specifically, the fixed-side clamp assembly 32 is further provided with a fixed-side clamp adjustment assembly 324 for adjusting the vertical movement of the lower clamp 322. In this embodiment, the fixed-side clamp adjustment assembly allows the fixed-side clamp assembly to adjust the height of the lower clamp on the lower clamp fixing part according to the size of the product. Of course, it is not limited to this; other methods can be used to achieve height adjustment of the lower clamp on the lower clamp fixing part.

[0046] Specifically, the main body 1 is also equipped with a control panel 5. In this embodiment, the control panel can control parameters such as the rotation speed, angle, or number of tests of the rocker arm of the shaft durability testing machine.

[0047] Working principle: During use, the lower clamp is adjusted to match the product size using the side clamp adjustment component. The upper clamp is then adjusted to the appropriate position using the escape adjustment component and the upper clamp groove. One end of the product is placed on the lower clamp and secured with the lower clamp fastener. The other end of the product is secured with the upper clamp. The control panel is used to set parameters such as the rotation speed, angle, and number of tests for the rocker arm. The motor is then started to rotate, driving the rocker arm to rotate and causing the upper clamp to clamp one end of the product, which then begins to fold repeatedly, thus completing the durability test of the product's shaft.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
