[0039] The testing equipment 100 provided in this application embodiment can be used to test the structural strength of various test components, which can be the plastic shell of electrical equipment such as chargers and adapters.

[0040] Please refer to the following: Figure 1 and Figure 2 The test equipment 100 provided in the embodiments of this application will now be described.

[0041] The test equipment 100 provided in this application embodiment includes a housing 10, an adjustment component 20, and a test component 30.

[0042] The enclosure 10 has an inner cavity 11. An adjustment component 20 is disposed in the inner cavity 11, and the adjustment component 20 is used to adjust the temperature and humidity in the inner cavity 11.

[0043] like Figure 1 and Figure 2 As shown, the adjustment component 20 is disposed in the inner cavity 11 and contacts the air in the inner cavity 11 to change the temperature and humidity of the air in the inner cavity 11, thereby achieving the effect of changing the temperature and humidity in the inner cavity 11. The test piece 200 is located in the inner cavity 11, and the temperature and humidity in the inner cavity 11 are the temperature and humidity of the environment in which the test piece 200 is located. On the one hand, by adjusting the component 20, the temperature of the test piece 200 and the humidity of the environment in which the test piece 200 is located are changed, so that the test equipment 100 provided in this application can measure the structural strength of the test piece 200 under different temperature and humidity conditions. On the other hand, the adjustment component 20 can adjust the rate of temperature change in the inner cavity 11 so that the test equipment 100 provided in this application can measure the structural strength of the test piece 200 under the condition of drastic temperature change.

[0044] The test assembly 30 includes a clamping device 31, an actuating device 32, and a measuring device 33. Both the clamping device 31 and the actuating device 32 are located in the inner cavity 11. The clamping device 31 is provided with a clamping groove 311 to clamp the test piece 200. The clamping groove 311 has an opening to allow the test piece 200 to enter the clamping groove 311. The actuating device 32 is located on the opening side of the clamping groove 311 and can move toward the clamping device 31 to apply a force to the test piece 200. The measuring device 33 is located on either the actuating device 32 or the clamping device 31 to measure the force applied to the test piece 200.

[0045] It should be noted that the first direction in the following text is... Figure 1 The x-direction shown below, the second direction in the following text is Figure 1 The y-direction shown below, and the third direction in the following text are... Figure 1 The z-direction shown is orthogonal to any two of the first direction x, the second direction y, and the third direction z.

[0046] like Figure 2 As shown, the clamping device 31 is disposed on the side of the test piece 200 along the third direction z, and part of the clamping device 31 extends to the side of the test piece 200 along the first direction x, and part of the clamping device 31 extends to the side of the test piece 200 along the second direction y, thereby clamping the test piece 200 by the clamping device 31.

[0047] The clamping groove 311 is located at the end of the clamping device 31 along the third direction z, and the opening of the clamping groove 311 extends away from the clamping device 31 along the third direction z. After the test piece 200 is placed into the clamping groove 311, one end of the test piece 200 along the third direction z abuts against the bottom of the clamping groove 311, and part of the test piece 200 extends to the outside of the opening of the clamping groove 311.

[0048] The actuating device 32 is located on the side of the test piece 200 away from the clamping device 31. When the test piece 200 is installed on the clamping device 31, the test piece 200 is located between the actuating device 32 and the clamping device 31, and at least part of the actuating device 32 can move toward the test piece 200 so that the test piece 200 is clamped between the actuating device 32 and the clamping device 31. The actuating device 32 adjusts the force received by the test piece 200 until the test piece 200 suffers structural damage.

[0049] The measuring device 33 is connected to the action device 32 or the clamping device 31 to measure the reaction force of the test piece 200 on the action device 32 or the clamping device 31 before failure, thereby obtaining the force of the action device 32 and the clamping device 31 received by the test piece 200 before structural failure, obtaining the stress limit of the test piece 200, and then evaluating the structural strength of the test piece 200.

[0050] The beneficial effects of the testing equipment 100 provided in this application are as follows: Compared with the prior art, the testing equipment 100 provided in this application can dynamically adjust the temperature and humidity inside the chamber 10 by adjusting the component 20, so that the temperature and humidity around the test piece 200 can be dynamically adjusted. The action component can apply external force to the test piece 200 under different temperature and humidity environments, so that the testing equipment 100 provided in this application can measure the stress limit and other structural strengths of the test product under different temperature and humidity environments.

[0051] In some embodiments, the housing 10 is provided with a door 12 to open and close the inner cavity 11.

[0052] In some embodiments provided in this application, the regulating component 20 includes a heater 21, a condenser 25, an evaporator 22, a humidifier 23, and a circulating fan 24. The heater 21, the evaporator 22, and the humidifier 23 are all located on the air outlet side of the circulating fan 24.

[0053] like Figure 1 As shown, an air duct 112 is provided in the inner cavity 11. The air duct 112 has an air inlet and an air outlet, both of which are connected to other spaces in the inner cavity 11. An air flow channel 111 is formed inside the air duct 112. A circulating fan 24 is located in the air flow channel 111. The air in the inner cavity 11 is driven by the circulating fan 24 to circulate through the air flow channel 111. A heater 21, an evaporator 22, and a humidifier 23 are all located in the air flow channel 111, and the heater 21, the evaporator 22, and the humidifier 23 are all located upstream of the circulating fan 24.

[0054] Thus, the temperature in the inner cavity 11 is increased by the heater 21, the temperature in the inner cavity 11 is decreased by the evaporator 22, and the humidity in the inner cavity 11 is increased by the humidifier 23. The heater 21, evaporator 22 and humidifier 23 are all located in the air flow channel 111 and change the temperature and humidity in the inner cavity 11 by convection.

[0055] The heater 21 is composed of a high-power electric heating tube. When the temperature inside the inner cavity 11 is lower than the required temperature, the heating tube is powered on to heat the air around it. The heated air around the heating tube is sent to the inner cavity 11 by the circulating fan 24, which increases the temperature of the inner cavity 11. If the temperature inside the inner cavity 11 is higher than the set value, the heating tube is powered off and stops heating.

[0056] In some embodiments, the airflow velocity within the airflow channel 111 is adjustable so that the rate of temperature change within the cavity 11 is adjustable.

[0057] The test equipment 100 provided in this application also includes a cooling pipe (not shown in the figure), the condenser 25 and the evaporator 22 are connected through the cooling pipe, and a cooling medium is provided in the cooling pipe. A compressor 26 is provided between the condenser 25 and the evaporator 22 to reduce the temperature of the cooling medium input into the evaporator 22 through the compressor 26 and the condenser pipe, thereby regulating the temperature in the inner cavity 11 through the evaporator 22.

[0058] When the relative humidity inside the inner cavity 11 is lower than the required value, the humidifier 23 is powered on and heats the water to boiling point, which is then sent into the air duct 111 by a fan to achieve the purpose of humidification.

[0059] When the relative humidity inside the inner cavity 11 is greater than the required value, the compressor 26 is started to cool the air. The air in the air channel 111 is cooled to below the dew point temperature by the evaporator 22, and the water in the air is precipitated to achieve the effect of dehumidification.

[0060] In some embodiments provided in this application, the clamping device 31 includes a base 312, a first clamping member 313 and a second clamping member 315, the first clamping member 313 and the second clamping member 315 being arranged at a relative interval along a first direction x to form a clamping groove 311 between the first clamping member 313 and the second clamping member 315.

[0061] like Figure 4 As shown, the first clamping member 313 and the second clamping member 315 are arranged opposite each other along the first direction x, and the seat body 312 is located on the side of the first clamping member 313 and the second clamping member 315 along the third direction z. A clamping groove 311 is formed between the first clamping member 313, the second clamping member 315 and the seat body 312. The clamping groove 311 penetrates the clamping device 31 along the second direction y, and the opening of the clamping groove 311 extends along the third direction z.

[0062] The position of the first clamping member 313 relative to the base 312 along the first direction x is adjustable, and the position of the second clamping member 315 relative to the base 312 along the first direction x is adjustable, so as to adjust the size of the clamping groove 311 in the first direction x.

[0063] like Figure 4 and Figure 5 As shown, the seat 312 includes a first support 3121 and a second support 3122. The first support 3121 is located on the side of the first clamping member 313 away from the second clamping member 315. A first lead screw 314 is provided on the first support 3121. The first lead screw 314 is threadedly assembled to the first support 3121 along the first direction x, and the end of the first lead screw 314 is rotatably connected to the first clamping member 313 so as to adjust the position of the first clamping member 313 in the first direction x by rotating the first lead screw 314 along its axis.

[0064] The second support 3122 is located on the side of the second clamping member 315 away from the first clamping member 313. The second support 3122 is provided with a second lead screw 316. The second lead screw 316 is threaded onto the second support 3122 along the first direction x, and the end of the second lead screw 316 is rotatably connected to the second clamping member 315 so as to adjust the position of the second clamping member 315 in the first direction x by rotating the second lead screw 316 along its axis.

[0065] Therefore, by adjusting the position of the first clamping member 313 in the first direction x and the position of the second clamping member 315 in the first direction x, on the one hand, the width of the clamping groove 311 in the first direction x can be adjusted so that the clamping assembly can be compatible with test pieces 200 of different sizes. On the other hand, the position of the clamping groove 311 in the first direction x can be adjusted so that the part of the test piece 200 pressed by the actuating device 32 can be adjusted, thereby realizing the measurement of various parts of the test piece 200.

[0066] In some embodiments provided in this application, the first clamping member 313 is provided with a first clamping abutment 3132, at least a portion of the first clamping abutment 3132 can extend to the side of the first clamping member 313 facing the second clamping member 315 to be adapted to abut against the object to be tested in the clamping groove 311, and the distance between the end of the first clamping abutment 3132 near the second clamping member 315 and the first clamping abutment 3132 is adjustable;

[0067] The second clamping member 315 is provided with a second clamping member 3152. At least a portion of the second clamping member 3152 can extend to the side of the second clamping member 315 facing the first clamping member 313 to be adapted to abut against the object to be tested in the clamping groove 311. The distance between the end of the second clamping member 3152 near the first clamping member 313 and the second clamping member 3152 is adjustable.

[0068] like Figure 4 As shown, the first clamping member 3132 extends along the first direction x, and at least a portion of the first clamping member 3132 can extend to the side of the first clamping member 313 facing the second clamping member 315, that is, at least a portion of the first clamping member 3132 can extend into the clamping groove 311. The first clamping member 3132 is threadedly fitted to the first clamping member 313 so that the end of the first clamping member 3132 abuts against the surface of the test piece 200 in the clamping groove 311.

[0069] like Figure 4 and Figure 6 As shown, the second clamping member 3152 extends along the first direction x, and at least a portion of the second clamping member 3152 can extend to the side of the second clamping member 315 facing the first clamping member, that is, at least a portion of the second clamping member 3152 can extend into the clamping groove 311. The second clamping member 3152 is threadedly fitted to the second clamping member 315 so that the end of the second clamping member 3152 abuts against the surface of the test piece 200 in the clamping groove 311.

[0070] Therefore, by clamping the test piece 200 in the clamping groove 311 with the first clamping member 3132 and the second clamping member 3152, the test piece 200 is fixed in the clamping groove 311 to prevent it from falling out of the clamping groove 311 when subjected to force. On the other hand, by fixing the test piece 200 with the first clamping member 3132 and the second clamping member 3152, the contact area with the test piece 200 is reduced, thereby reducing the supporting effect of the clamping device 31 on the test piece 200 and improving the measurement accuracy of the structural strength of the test piece 200.

[0071] In some embodiments provided in this application, the position of the first clamping member 3132 along the second direction y is adjustable, and the second direction y is orthogonal to the first direction x;

[0072] And / or, the position of the first clamping member 3132 along the second direction y is adjustable, and the second direction y is orthogonal to the first direction x.

[0073] In some embodiments, the positions of the first clamping member 3132 and the second clamping member 3152 in the second direction y can both be adjusted.

[0074] like Figure 4 As shown, the first clamping member 313 is provided with a first sliding groove 3133, the first sliding groove 3133 is provided with a first slider 3131, the first clamping member 3132 is threadedly assembled to the first slider 3131, the first sliding groove 3133 extends along the second direction y so that the first slider 3131 can move in the second direction y, thereby adjusting the position of the first clamping member 3132 in the second direction y.

[0075] The second clamping member 315 is provided with a second sliding groove 3153, and a second slider 3151 is provided in the second sliding groove 3153. The second clamping member 3152 is threadedly assembled to the second slider 3151. The second sliding groove 3153 extends along the second direction y so that the second slider 3151 can move in the second direction y, thereby adjusting the position of the second clamping member 3152 in the second direction y.

[0076] Therefore, the clamping position of the clamping device 31 on the workpiece 200 can be adjusted by adjusting the position of the first slider 3131 and the second slider 3151 in the second direction y. By adjusting different clamping positions and performing multiple measurements on the workpiece 200, the supporting effect of the clamping device 31 on the workpiece 200 can be eliminated, thereby improving the measurement accuracy of the structural strength of the workpiece 200.

[0077] In other embodiments, only the position of the first clamping member 3132 in the second direction y is adjustable, while the position of the second clamping member 3152 in the second direction y is fixed and cannot be adjusted.

[0078] In some embodiments, such as Figure 5 As shown, there are multiple first sliders 3131, multiple second sliders 3151, and multiple first clamping parts 3132. The first clamping parts 3132 are set to correspond one-to-one with the first sliders 3131, and the second sliders 3151 are set to correspond one-to-one with the second clamping parts 3152.

[0079] In other embodiments, the first slider 3131 is provided with a plurality of first clamping members 3132, and the plurality of first clamping members 3132 on the first slider 3131 are arranged along the third direction z. The second slider 3151 is provided with a plurality of second clamping members 3152, and the plurality of second clamping members 3152 on the second slider 3151 are arranged along the third direction z.

[0080] In some embodiments provided in this application, the clamping device 31 is detachably disposed in the inner cavity 11. There are multiple clamping devices 31, and the clamping grooves 311 in the multiple clamping devices 31 have different shapes so that the test assembly 30 can be compatible with test pieces of different shapes.

[0081] The clamping device 31 is detachably connected to the inner wall of the inner cavity 11. By replacing different clamping parts and clamping slots 311 in the clamping device 31, and by replacing clamping slots 311 of different shapes in the clamping device 31, the clamping device 31 can clamp test pieces 200 of different shapes. Thus, the test equipment 100 provided in this application can measure test pieces 200 of different shapes, thereby improving the versatility of the test equipment 100 provided in this application.

[0082] In some embodiments provided in this application, the test assembly 30 further includes a moving device 40, which has a fixed end and a movable end. The fixed end is located on the outside of the inner cavity 11, and the movable end can extend into the inner cavity 11 and be connected to the actuating device 32. The movable end can move along the arrangement direction of the clamping device 31 and the actuating device 32.

[0083] like Figure 1 and Figure 2 As shown, the moving device 40 includes a first lead screw 41, a second lead screw 42, a moving frame 43, a reduction assembly, and a drive component 44. The first lead screw 41 and the second lead screw 42 extend along a third direction z. The first lead screw 41 and the second lead screw 42 are arranged parallel to each other along a first direction x. One end of the moving frame 43 along the first direction x is connected to the first lead screw 41 through a ball screw nut, and the other end of the moving frame 43 along the first direction x is connected to the second lead screw 42 through a ball screw nut.

[0084] The driving component 44 can be a motor. The driving component is connected to the first lead screw 41 and the second lead screw 42 through a reduction assembly, so that the first lead screw 41 and the second lead screw 42 can rotate synchronously, so that the moving frame 43 moves along the third direction z, and at least part of the moving frame 43 forms a moving end, and the ends of the first lead screw 41 and the second lead screw 42 form a fixed end.

[0085] The first lead screw 41 and the second lead screw 42 penetrate the inner cavity 11 along the third direction z. The moving frame 43 is located in the inner cavity 11. The deceleration assembly and the drive component are located on the outside of the inner cavity 11 to reduce the impact of temperature and humidity changes in the inner cavity 11 on the deceleration assembly and the drive component.

[0086] In some embodiments, the rotational speed and torque of the drive member 44 are adjustable, so that the moving speed of the moving end in the third direction z is adjustable, and the force exerted by the action device 32 on the test member 200 is adjustable. On the one hand, the structural strength of the test member 200 under static load can be measured, and on the other hand, the structural strength of the test member 200 under different impact loads can be measured.

[0087] like Figure 7 As shown, in some embodiments, the reduction assembly includes a first reduction gear 46, a second reduction gear 47, and a synchronous belt 45. The synchronous belt 45 is wound around the outside of the first reduction gear 46, the second reduction gear 47, and the output end of the drive member 44. The radius of the first reduction gear 46 is larger than the radius of the first lead screw 41, and the first reduction gear 46 is connected to the first lead screw 41. The radius of the second reduction gear 47 is larger than the radius of the second lead screw 42, and the second reduction gear 47 is connected to the second lead screw 42, so as to drive the first lead screw 314 and the second lead screw 42 to rotate synchronously through the drive member 44.

[0088] Either the first reduction gear 46 or the second reduction gear 47 is equipped with a photoelectric sensor to detect the rotational speed of the first lead screw 41 or the second lead screw 42, thereby obtaining the moving speed of the moving end and realizing the measurement of the moving speed of the actuating device 32 in the third direction z.

[0089] In some embodiments provided in this application, the measuring device 33 is disposed between the movable end and the actuating device 32.

[0090] like Figure 2 As shown, the measuring device 33 is a mechanical sensor. The measuring device 33 is connected between the movable end and the actuating device 32. The measuring device 33 measures the reaction force of the test piece 200 on the actuating device 32 or the clamping device 31 before it is damaged. The measuring device 33 then obtains the force of the test piece 200 received by the actuating device 32 and the clamping device 31 before structural damage occurs, thus obtaining the stress limit of the test piece 200 and evaluating the structural strength of the test piece 200.

[0091] In some embodiments provided in this application, the test device 100 further includes a monitoring component (not shown in the figure), which is disposed in the inner cavity 11 and includes a thermometer and a hygrometer. The monitoring component is used to monitor the temperature and humidity in the inner cavity 11.

[0092] Both the thermometer and the hygrometer are located in the inner cavity 11. On the one hand, the temperature and humidity of the environment in which the test component 200 was located before the failure can be measured by the thermometer and the hygrometer to evaluate the structural strength of the test component 200 under different environments. On the other hand, the temperature change rate in the inner cavity 11 can be measured by the thermometer to evaluate the structural strength of the test component 200 under temperature change conditions.

[0093] In some embodiments provided in this application, the test device 100 further includes a control component 50, which is disposed on the outside of the inner cavity 11. The control component 50 is electrically connected to the adjustment component 20 and the test component 30, respectively, and the control component 50 is used to control the test component 30 and the adjustment component 20, respectively.

[0094] like Figure 2 and Figure 3 As shown, the control component 50 is located on the outer side of the housing 10 and the inner cavity 11, so as to reduce the impact of temperature and humidity changes in the inner cavity 11 on the control component 50.

[0095] The control component 50 includes a touch screen. The adjustment component 20, the test component 30, and the movement component are all electrically connected to the control component 50 so as to display the working status of the adjustment component 20, the test component 30, and the movement component through the touch screen, and to control and adjust the adjustment component 20, the test component 30, and the movement component through the touch screen.

[0096] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
