Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing technology, and in particular to a noise reduction flipping 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, because the drive motor, base, and rotating components are connected together, allows sound to be transmitted through the connecting parts between the three, which can easily interfere with the test results and affect the test effectiveness. 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 noise-reducing flipping mechanism that can reduce mutual interference between structures within the testing equipment, resulting in more accurate results.
[0005] The noise reduction flipping mechanism according to an embodiment of the present invention includes:
[0006] The first base is the first component used to fix the test piece;
[0007] The second base is elastic;
[0008] The rotating assembly includes a swing arm, a flexible coupling, and a first power component. The swing arm is rotatably mounted on the second base and is used to fix the second component of the test piece. The first power component is connected to the swing arm through the flexible coupling to rotate the swing arm.
[0009] According to some embodiments of the present invention, the second base includes a fixed bracket, a first elastic bracket, and a second elastic bracket. The first elastic bracket and the second elastic bracket are respectively disposed on both sides of the first base. The two ends of the fixed bracket are respectively disposed on the first elastic bracket and the second elastic bracket. The swing arm is disposed on the fixed bracket.
[0010] According to some embodiments of the present invention, the first base is provided with a plurality of first positioning members, which are used to fix the first component of the test piece.
[0011] According to some embodiments of the present invention, the first positioning element is a suction cup.
[0012] According to some embodiments of the present invention, the swing arm is provided with a plurality of second positioning members, which are used to fix the second component of the test piece.
[0013] According to some embodiments of the present invention, the second positioning element is a suction cup.
[0014] According to some embodiments of the present invention, the first base is provided with a limiting arm, which is located behind the swing arm and can abut against the swing arm.
[0015] According to some embodiments of the present invention, the swing arm is provided with a rotation center rod, which is located in the extension direction of the elastic coupling, and the rotation center rod is used to locate the rotation center of the test piece.
[0016] According to some embodiments of the present invention, the swing arm includes a rotating shaft and a positioning shaft. The rotating shaft is rotatably disposed on the base and has a plurality of positioning holes. The positioning shaft is installed in the positioning holes.
[0017] On the other hand, the soundproof box according to the present invention includes the noise reduction flipping mechanism according to the above embodiment of the present invention.
[0018] The embodiments of this utility model have at least the following beneficial effects:
[0019] The first and second bases are both mounted on the frame. The first base is fixed to the frame, while the second base is flexible, which reduces vibration between the frame and the second base. The rotating component is mounted on the second base and does not contact the first base, thus reducing noise interference between the swing arm and the first base. The flexible coupling contains a pre-compressed rubber elastic compound, which provides additional strength and extends service life. This coupling can accommodate all types of misalignment. The hub is made of high-strength aluminum alloy, which is both lightweight and corrosion-resistant. The rubber component is mainly used for shock absorption, making power transmission smooth and quiet, thereby protecting the drive force and the driving machine. Since the first power component is prone to making noise, the connection between the first power component and the swing arm through the flexible coupling reduces the noise transmitted between the first power component and the swing arm.

[0036] Reference Figures 1-3 The noise reduction flipping mechanism according to an embodiment of the present invention includes:
[0037] The first base 100 is a first component used to fix the test piece;
[0038] The second base 200 is elastic;
[0039] The rotating assembly 300 includes a swing arm 310, an elastic coupling 320, and a first power component 330. The swing arm 310 is rotatably mounted on the second base 200 and is used to fix the second component of the test piece. The first power component 330 is connected to the swing arm 310 through the elastic coupling 320 to make the swing arm 310 rotate.
[0040] According to the embodiments of this utility model, by such arrangement, at least the following effects can be achieved: the first base 100 and the second base 200 are both disposed on the frame. The first base 100 is fixedly disposed on the frame, while the second base 200 is elastic, which can reduce the vibration between the frame and the second base 200. The rotating component 300 is disposed on the second base 200 and does not contact the first base 100, thereby reducing the sound interference between the swing arm 310 and the first base 100. The elastic coupling 320 contains an elastic compound of pre-compressed rubber, which can provide additional strength and extend service life. This coupling can accommodate all types of misalignment. The hub material is high-strength aluminum alloy, which is both lightweight and corrosion-resistant. The rubber component is mainly used for shock absorption, making power transmission smooth and quiet, thereby protecting the driving force and the driving machine. Since the first power component 330 is prone to making noise, the connection between the elastic coupling 320 and the swing arm 310 can reduce the sound transmitted between the first power component 330 and the swing arm 310.
[0041] The first and second components of the test piece can be understood as follows: the test piece can be an electronic product with a folding function, such as a laptop or a folding mobile phone, and the first and second components refer to the two parts of the test piece that can be folded.
[0042] The first power component 330 can be a rotary motor, a rotary cylinder, etc.
[0043] In some embodiments, the second base 200 includes a fixed bracket 210, a first elastic bracket 220, and a second elastic bracket 230. The first elastic bracket 220 and the second elastic bracket 230 are respectively disposed on both sides of the first base 100. The two ends of the fixed bracket 210 are respectively disposed on the first elastic bracket 220 and the second elastic bracket 230. The swing arm 310 is disposed on the fixed bracket 210. The first elastic bracket 220 and the second elastic bracket 230 are made of elastic materials such as rubber or silicone, which can reduce vibration or sound transmitted from other locations. The fixed bracket 210 connects the first elastic bracket 220 and the second elastic bracket 230. The fixed bracket 210 is made of rigid material, which facilitates the installation of the rotating component 300 on the fixed bracket 210. The fixed bracket 210 and the first base 100 are separated, so that vibration is not transmitted. A cavity is provided below the first base 100, and the fixed bracket 210 passes through the cavity, so that the two ends of the fixed bracket 210 are respectively connected to the first elastic bracket 220 and the second elastic bracket 230.
[0044] In some embodiments, the first base 100 is provided with a plurality of first positioning members 110, which are used to fix the first component of the test piece. The first positioning members 110 can fix the first component of the test piece, ensuring that one end of the test piece remains stationary.
[0045] In some embodiments, the first positioning element 110 is a suction cup. The suction cup can generate negative pressure, which has an adsorption effect on the test piece, allowing the test piece to be fixed on the first base 100 without damaging the test piece.
[0046] In some embodiments, the swing arm 310 is provided with a plurality of second positioning members 311, which are used to fix the second component of the test piece. The second positioning members 311 can fix the second component of the test piece, ensuring that the other end of the test piece remains stationary.
[0047] In some embodiments, the second positioning element 311 is a suction cup. The suction cup can generate negative pressure, which has an adsorption effect on the test piece, allowing the test piece to be fixed on the first base 100 without damaging the test piece.
[0048] In some embodiments, the first base 100 is provided with a limiting arm 120, which is located behind the swing arm 310 and can abut against the swing arm 310. This prevents the swing arm 310 from swinging too much, which could cause the electronic product to swing excessively and thus damage the electronic product.
[0049] In some embodiments, the swing arm 310 is provided with a rotation center rod 312, which is located in the extending direction of the flexible coupling 320. The rotation center rod 312 is used to position the rotation center of the test piece. The rotation center rod 312 is located in the extending direction of the flexible coupling 320, which is also the extending direction of the first power member 330, i.e., the center of the rotating shaft 313. Positioning the rotation center of the test piece by the rotation center rod 312 facilitates the mounting of the test piece on the first base 100.
[0050] In some embodiments, the swing arm 310 includes a rotating shaft 313 and a positioning shaft 314. The rotating shaft 313 is rotatably mounted on the base and has a plurality of positioning holes. The positioning shaft 314 is installed in the positioning holes. The swing arm 310 includes the rotating shaft 313 and the positioning shaft 314, which are separately arranged and can be installed and removed. Through the positioning holes provided on the rotating shaft 313, the positioning shaft 314 can be installed in the corresponding positioning hole of the rotating shaft 313 as needed to adapt to products of different models and sizes.
