[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a conflicting connection or an integral connection; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances; in the description of the present invention, unless otherwise specified, "multiple" and "several" mean two or more.

[0023] like Figure 1 and Figure 2 As shown, this embodiment provides a module button performance test fixture, including a test container 1 for containing water, and a click simulation mechanism for clicking the module button; the test container 1 is provided with a fixed bracket 2 for fixing the click simulation mechanism, the click simulation mechanism includes a base 9, a module fixing seat 3 arranged on the base 9 for fixing the module button to be tested, and a power component for repeatedly clicking the module button to be tested, the base 9 is vertically installed on the fixed bracket 2, and the module fixing seat 3 is located below the power component. During the test, the module button to be tested is fixedly installed on the module fixing seat 3, and the click simulation mechanism is placed in the test container 1, water is filled into the test container 1, so that the module button to be tested on the module fixing seat 3 is completely immersed in water, and the test container 1 is sealed. Under this environmental condition, the module button to be tested immersed in water is automatically and repeatedly clicked by the power component, wherein the click frequency and the number of clicks can be set by oneself, which greatly reduces the labor cost and improves the test efficiency; and it can realize the click test under different water pressures and the waterproof performance detection of the product.

[0024] As a specific implementation method, Figure 2As shown, the power assembly includes a fixed plate 10, a click-extending rod 5, a fixed bearing seat 4, a transmission rod 6 and a driving member. The fixed plate 10 is vertically fixed on the base 9. The click-extending rod 5 is fixedly installed on the fixed plate 10 at one end close to the module fixing seat 3 through the fixed bearing seat 4, and the end of the click-extending rod 5 is directly facing the module button to be tested on the module fixing seat 3. One end of the transmission rod 6 is hinged to the end of the click-extending rod 5 away from the module fixing seat 3, and the other end of the transmission rod 6 is connected to the driving member. During the test, the driving member drives the transmission rod 6 to move, thereby driving the click-extending rod 5 to reciprocate to click the module button to be tested. In this process, the fixed bearing seat 4 plays a limiting and guiding role for the movement of the click-extending rod 5.

[0025] Optionally, the driving member includes a power motor 8 and a turntable 7, the power motor 8 is fixedly mounted on the fixing plate 10, the turntable 7 is rotatably connected to the power motor 8, and the transmission rod 6 is connected to the turntable 7. The turntable 7 is driven to rotate by the power motor 8, and the rotation of the turntable 7 drives the transmission rod 6 to move periodically, thereby driving the click extension rod 5 to move periodically.

[0026] Optimally, a plurality of mounting holes 11 are provided on the turntable 7, and the distances between each mounting hole 11 and the center of the turntable 7 are different. When the end of the transmission rod 6 is connected to different mounting holes 11 of the turntable 7, the travel of the transmission rod 6 driven by the rotation of the turntable 7 is different. Therefore, according to the distance between the click extension rod 5 and the button of the module to be tested on the module fixing seat 3, the corresponding mounting hole position for connecting the transmission rod 6 and the turntable 7 can be selected, thereby expanding the application range of the test fixture.

[0027] Optionally, for module buttons to be tested of different shapes and sizes, a detachable connection between the module fixing seat 3 and the base 9 can be designed. In this way, for different module buttons to be tested, only the corresponding module fixing seat 3 needs to be replaced, which is easy to operate and expands the scope of application of the test fixture.

[0028] For replacement and installation of the keys of the module to be tested, in some embodiments, the fixed bracket 2 can be designed to be a telescopic structure, and the base 9 of the click simulation mechanism can be fixedly installed on the fixed bracket 2. The module fixing seat 3 can be moved out of the water surface or the test container by the extension and contraction of the fixed bracket 2, so as to facilitate the replacement of the keys of the module to be tested. In other embodiments, the base 9 of the click simulation mechanism can be designed to be slidably connected to the fixed bracket 2, and the base 9 can be slid and lifted on the fixed bracket 2 to move the module fixing seat 3 out of the water surface or the test container, so as to achieve the purpose of replacing the keys of the module to be tested.

[0029] As a specific implementation, the test container 1 includes a container body and a container cover, both of which are made of transparent materials to facilitate observation of the test situation; the container body and the container cover are sealed and connected by a flange, and a water inlet (not shown in the figure) is provided at the bottom of the container body for water intake. The water inlet is set at the bottom of the container body, and water intake will not have a significant impact on the click simulation mechanism, thereby ensuring the service life of the click simulation mechanism. Of course, the water in the test container 1 can be discharged through the water inlet, or an additional drain port can be set at the bottom of the container body for discharge; and during the test process, the air tightness of the water inlet and the drain port needs to be ensured.

[0030] In an optional implementation manner, an air inlet (not shown in the figure) is provided on the container body, and a pressure sensor for detecting the air pressure value in the container body is provided in the container body. Compressed gas of a certain pressure is introduced into the sealed test container 1 through the air inlet to simulate the water pressure value generated by the corresponding water depth. For example, the water pressure value generated by a water depth of one meter is about 10Kpa. Adding 10Kpa of compressed gas into the sealed test container 1 will form a pressure of 10Kpa on the water surface in the test container 1. Placing the buttons of the module to be tested underwater can reflect the environmental test conditions of the buttons of the module to be tested at a water depth of one meter. In this way, click tests under different water pressures can be realized, and at the same time, the power components of the click simulation mechanism (i.e., the power motor 8, the transmission rod 6, and the click extension rod 5) can be avoided from being immersed in water, thereby reducing the movement resistance of the power components and increasing the service life of the power components.

[0031] The above examples are merely illustrative of the present invention and do not constitute a limitation on the protection scope of the present invention. All designs that are identical or similar to the present invention fall within the protection scope of the present invention.
