Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a vibration filtering testing device. Background Technology

[0002] Products with vibration functions typically require vibration function testing after production. To improve testing efficiency, multiple products are usually tested simultaneously. For example, a utility model patent with authorization announcement number CN212964058U discloses a testing device for fascia guns, including a fixing frame and a test fixing plate. The fixing frame is used to fix the body of the fascia gun, and one side of the fixing frame is used to expose the massage head of the fascia gun. The test fixing plate is located on the side of the fixing frame where the massage head is exposed, and the side of the test fixing plate facing the fixing frame has a test simulation element for simulating human skin. The test simulation element is used to strike the massage head of the fascia gun. This testing device can simultaneously fix multiple products to be tested using the fixing frame and use the test simulation element to test the vibration amplitude and noise of the products.

[0003] However, for products directly applied to the human body, especially massage devices, the accuracy requirements for vibration detection are extremely high. Although the aforementioned products have cushioning pads installed on the upper surface of the substrate within the housing space, the fixing plate used to secure the product is directly rigidly assembled with it. When testing products simultaneously, the vibration of a single product can be transmitted through the base to adjacent products, causing interference between multiple products and resulting in distorted test data. Furthermore, the fixing frame only secures the product through corresponding upper and lower support grooves and cover grooves, and then fixes it with side spring clips. During vibration testing, if the first and second clamping components loosen, the groove walls of the support grooves and cover grooves can easily cause hard friction with the product surface, especially scratching precision electronic components or surface-treated products. In addition, for some multi-level adjustable products, a testing device is needed that can simultaneously test different vibration levels. Utility Model Content

[0004] Therefore, in order to solve the above problems, this utility model provides a vibration filtering test device.

[0005] This utility model is achieved through the following technical solution:

[0006] A vibration damping testing device includes a base with at least one mounting seat on it. A vibration damping and buffering assembly is connected between the mounting seat and the base. A flexible positioning block is embedded in the mounting seat, and a mounting groove for placing a product is provided in the flexible positioning block. The opening of the mounting groove is located on the upper surface of the mounting seat. The mounting seat is also connected to a power connection cable, the output end of which extends from the bottom of the mounting seat into the mounting groove. A triggering mechanism is provided on one side of the mounting seat. The triggering mechanism includes a trigger rod passing through the side wall of the mounting seat. The trigger rod includes a pressing end located outside the mounting seat and a trigger end extending into the mounting groove. A moving detection mechanism is also provided on the other side of the mounting seat. The moving detection mechanism includes a moving platform slidably disposed on one side of the mounting seat. At least one detection component is disposed on the moving platform, and each detection component corresponds to a mounting seat.

[0007] Preferably, the shock absorption assembly includes four shock-absorbing springs arranged around the bottom perimeter of the mounting base, with the bottom end of each shock-absorbing spring fixed to the base by bolts and its top end fixed to the bottom of the mounting base by bolts.

[0008] Preferably, the bottom of the mounting base is provided with a through hole for the power connection cable to pass through, the bottom of the flexible positioning block is provided with a terminal block for fixing the power connection cable, the terminal block is provided with a wiring groove for fixing the power connection cable, the bottom of the mounting groove is provided with a wiring hole, and the wiring hole is located at the top of the wiring groove.

[0009] Preferably, the bottom of the flexible positioning block is provided with an assembly groove, the terminal block is embedded in the assembly groove, and the wiring hole is connected between the assembly groove and the mounting groove and is located directly above the wiring groove.

[0010] Preferably, two supports are vertically arranged on both sides of the base, and each support is provided with a guide drive component. Each guide drive component includes a fixed end and a telescopic end. The fixed end is fixed to the support, and the two sides of the mobile platform are connected to the telescopic ends of the two guide drive components.

[0011] Preferably, the connector is fixed on the side of the mobile platform opposite to the mounting base. The connector includes a first connecting block fixed on the mobile platform and a second connecting block for contacting the product. One end of the second connecting block is fixed to the first connecting block, and a sensor is provided at the other end.

[0012] Preferably, the mounting base has a first limiting groove for positioning the first connecting block on the side near the detection mechanism, and the flexible positioning block has a second limiting groove for positioning the second connecting block inside the first limiting groove.

[0013] Preferably, the flexible positioning block is provided with a clearance groove on the side near the triggering mechanism to avoid the triggering mechanism, the triggering end of the triggering rod passes through the clearance groove and extends into the interior of the mounting groove, and the free end of the triggering end is provided with an elastic pressing block.

[0014] Preferably, the triggering mechanism includes a first trigger lever for controlling the product switch and a second trigger lever for adjusting the product gear.

[0015] The beneficial effects of this utility model's technical solution are mainly reflected in:

[0016] 1. In the vibration filtering test device, each mounting base forms an elastic decoupling system with the base through the vibration damping and buffering components, so that the vibration energy of a single station is damped and absorbed by the vibration damping and buffering components, completely eliminating cross interference during multi-station testing and ensuring the accuracy of test data. At the same time, the mounting base is not rigidly assembled with the product, but is connected to the product using flexible positioning blocks. Therefore, the product will not be damaged by bumps during vibration testing, and the flexible positioning blocks further improve the buffering performance.

[0017] 2. The vibration filtering test device uses a retractable trigger mechanism to start or stop the product. The trigger mechanism can be set for the product's power switch and gear adjustment key, so that the product's performance at different gears can be tested simultaneously in one test. At the same time, an elastic pressing block can be set on the trigger end of the trigger mechanism to avoid damage to the product caused by excessive button pressure.

[0018] 3. In the vibration filtering test device, multiple detection components can be set on the mobile platform, and each detection component corresponds to a mounting base, thereby realizing the synchronous detection of multiple products. Each detection component determines the test position through a connector, thereby accurately determining the test area of ​​the product. The mobile platform can be slidably set on one side of the mounting base. During the test, the relative position of the detection component and the mounting base can be adjusted as needed. At the same time, when picking up or placing products, the detection components can avoid collisions by sliding. Attached Figure Description

[0030] This utility model discloses a vibration filtering test device, such as Figure 1 , Figure 2 As shown, it includes a base 1, on which at least one mounting seat 2 is provided. In some embodiments, multiple mounting seats 2 may be provided on the base 1. In a preferred embodiment, the multiple mounting seats 2 are arranged in parallel and spaced at equal intervals.

[0031] like Figures 3-7As shown, a shock-absorbing and buffering assembly is connected between the mounting base 2 and the base 1. The mounting base 2 is embedded with a flexible positioning block 3, and the flexible positioning block 3 is provided with a mounting groove 301 for placing the product. The opening of the mounting groove 301 is located on the upper surface of the mounting base 2, so that the product is inserted into the mounting groove 301 from the top of the mounting base 2. The shape and size of the mounting groove 301 can be adjusted according to the shape of the product, which will not be elaborated here. Using the flexible positioning block 3 to contact the product can improve the shock filtering performance and the buffering performance, and avoid product damage caused by hard assembly between the product and the mounting base 2.

[0038] like Figure 1 , Figure 2 As shown, in some embodiments, two supports 10 are vertically arranged on both sides of the base 1. Each support 10 is provided with a guide drive component 11. Each guide drive component 11 includes a fixed end and a telescopic end. The fixed end is fixed to the support 10. The two sides of the moving platform 6 are connected to the telescopic ends of the two guide drive components 11, so that the two guide drive components 11 synchronously drive the moving platform 6 to reciprocate and translate, thereby adjusting the relative distance between the moving platform 6 and the mounting base 2. In one embodiment, the guide drive component 11 can be a telescopic cylinder. A guide rod can also be provided on one side of the telescopic cylinder. The guide rod is parallel to the telescopic direction of the telescopic cylinder and is connected to the support 10 and the moving platform 6 respectively, further ensuring the stability of the moving platform 6 during the movement process.

[0039] like Figure 1 , Figure 2 As shown, in some embodiments, the connector 8 is fixed to the side of the mobile platform 6 opposite to the mounting base 2. The connector 8 includes a first connecting block fixed to the mobile platform 6 and a second connecting block for contacting the product. One end of the second connecting block is fixed to the first connecting block, and the other end is provided with a sensor 7.

In one embodiment, the second connecting block extends upward and bends towards the mounting base 2, and its curved surface conforms to the product, further ensuring the accuracy of the detection results.

[0040] like Figures 3-8 As shown, in some embodiments, the mounting base 2 is provided with a first limiting groove 303 for positioning the first connecting block on the side near the testing mechanism, and the flexible positioning block 3 is provided with a second limiting groove 304 for positioning the second connecting block inside the first limiting groove 303. Before testing the product, the moving platform 6 is moved towards the mounting base 2 until the connecting block moves into the first limiting groove 303 and the second connecting block moves into the second limiting groove 304, confirming that the testing mechanism is in place, and then testing begins, further ensuring the accuracy of the testing position.

[0041] like Figures 4-7 As shown, in some embodiments, the flexible positioning block 3 is provided with a clearance groove 305 on the side near the triggering mechanism to avoid the triggering mechanism. The triggering end 502 of the triggering rod 5 passes through the clearance groove 305 and extends into the interior of the mounting groove 301.
