[0033] The present application is described in detail below through one or more specific embodiments. A high temperature vibration test device, such as Figure 1 and Figure 2 As shown, it includes a test box 1, a vibration table 4 and a humidification structure;

[0034] The outer wall of the test box 1 is provided with a control terminal 3, and the control terminal 3 is electrically connected to the vibration table 4 and the humidification structure;

[0035] The vibration table 4 is located in the test box 1 and is fixedly connected to the inner wall of the test box 1. A heating tube 5 is embedded on the top of the vibration table 4. The object to be tested is located on the heating tube 5 to perform a high-temperature vibration test.

[0036] The humidifying part of the humidifying structure is located in the test box 1 and above the vibration table 4 , and the water supply part of the humidifying structure is located outside the test box 1 and is connected to the humidifying part through the side wall of the test box 1 .

[0037] Specifically, the test box 1 is a box structure with a door panel 2, and the door panel 2 is located on the side wall of the test box 1, so that the user can take and place the test item through the door panel 2; the control terminal 3 is located on the outer wall of the test box 1, so that the user can control the electrical appliances in the test box 1 (for example: the vibration table 4 and the humidification structure, etc.) outside the test box 1; an observation window is provided on the outer wall of the test box 1, so that the user can view the condition of the test item in the test box 1 through the observation window; the observation window and the control terminal 3 may be located on the door panel 2, or may not be located on the door panel 2.

[0038] Specifically, the bottom surface of the vibration table 4 is fixedly connected to the inner bottom wall of the test box 1, and can vibrate relative to the test box 1 under the control of the control end 3 and the power support, so as to drive the test object to be tested on the vibration table 4 to vibrate, thereby achieving a vibration effect on the test object to be tested; a heating tube 5 is provided on the top outer surface of the vibration table 4, and the heating tube 5 emits heat under the control of the control end 3 and the power support, so as to achieve heating of its surrounding environment, thereby providing a high-temperature environment for the test object to be tested on the heating tube 5, thereby achieving a high-temperature effect on the test object to be tested, and the heating tube 5 is embedded in the vibration table 4 so that the heating tube 5 is horizontally arranged relative to the outer surface of the vibration table 4, so as to avoid the uneven outer surface of the vibration table 4 affecting the state of the test object, thereby affecting the test results.

[0039] The humidifying part of the humidifying structure is located in the test box 1 and above the vibration table 4, so as to humidify the test items on the vibration table 4. The water supply part of the humidifying structure is used to supply water to the humidifying part. It is located outside the test box 1, which not only avoids occupying too much space in the test box 1, but also makes it convenient for users to add water to the water supply part and replenish the water supply part.

[0040] In this embodiment, by arranging a vibration table 4 and a humidification structure in the test box 1, and arranging a heating tube 5 on the vibration table 4, the test device has a humidification function on the basis of providing a high temperature and vibration environment, so that the humidity of the test object during the high temperature vibration test is not reduced due to the high temperature, thereby avoiding the situation where the high temperature vibration test performance of the test object is affected by humidity problems, which is beneficial to ensure the validity of the test results, and further improve the practicality and accuracy of the test device.

[0041] In some embodiments, the humidifying part of the humidifying structure includes a humidifying box 12 and a humidifying nozzle 13 connected to each other, the humidifying box 12 is connected to the water supply part and is located above the vibration table 4, and the humidifying nozzle 13 is connected to a side of the humidifying box 12 close to the vibration table 4;

[0042] The humidifying nozzles 13 are provided in plurality and are evenly arranged on the humidifying box 12 .

[0043] Specifically, the plurality of humidifying nozzles 13 are located on one side of the humidifying box 12 and are evenly arranged on the surface, so that the humidifying nozzles 13 can evenly spray the surface of the vibration table 4, thereby achieving even spraying of the objects to be tested located on the vibration table 4, so that the humidity of the objects to be tested is even, avoiding the influence of uneven humidity on the test results, which is beneficial to improving the practicability of the test device.

[0044] In some embodiments, the humidification part also includes a protection motor 11, a bearing 14 and a connecting pipe 10. The protection motor 11 is electrically connected to the control end 3 of the test box 1. The protection motor 11 and the bearing 14 are fixedly connected to the inner wall of the test box 1 and are located on two opposite side walls of the test box 1. One side of the humidification box 12 is connected to the protection motor 11, and the other side is connected to the bearing 14. The bearing 14 is fixedly connected to the humidification box 12 and is connected. One end of the connecting pipe 10 is connected to the humidification box 12 through the bearing 14, and the other end of the connecting pipe 10 passes through the side wall of the test box 1 and is connected to the water supply part.

[0045] Specifically, the protection motor 11 is located on the inner wall of the test box 1, and its output end is connected to a side wall of the humidification box 12 to drive the humidification box 12 to rotate, thereby driving the humidification nozzle 13 to rotate. The bearing 14 is located on an inner wall of the test box 1 opposite to the protection motor 11, and one end of the bearing 14 is connected to the inner wall of the test box 1, and the other end is connected to the side wall of the humidification box 12, so that when the humidification box 12 rotates driven by the protection motor 11, it rotates through the bearing 14, which can not only support the humidification box 12 by the bearing 14, which is beneficial to the smooth operation of the humidification box 12, but also make the humidification box 12 rotate smoothly, which is beneficial to the operation flexibility of the humidification part of the humidification structure.

[0046] One end of the bearing 14 connected to the humidification box 12 is a tubular structure, which is connected to the interior of the humidification box 12. The connecting pipe 10 is connected to the tubular structure to achieve communication with the humidification box 12. This can avoid the connecting pipe 10 from being directly connected to the humidification box 12, thereby avoiding the connecting pipe 10 from rotating with the humidification box 12, which is beneficial to the operation of the humidification part of the humidification structure.

[0047] In this embodiment, the bearing 14 and the protective motor 11 are provided to realize the stable rotation of the humidification box 12 and the humidification nozzle 13. On this basis, a connecting pipe 10 connecting the humidification box 12 and the water supply part is provided to realize the connection through the bearing 14. This can avoid the situation where the connecting pipe 10 rotates with the humidification box 12 and affects the operating stability of the humidification structure, which is beneficial to the operating stability of the humidification structure, and further beneficial to the practicability and promotion and application of the test device.

[0048] In some embodiments, the water supply unit includes a water tank 6 and a water pump 9, the water tank 6 is fixedly connected to the outer wall of the test box 1, the water pumping end of the water pump 9 is connected to the interior of the water tank 6, the water outlet end of the water pump 9 is connected to the connecting pipe 10, and the water pump 9 is electrically connected to the control end 3 of the test box 1.

[0049] Specifically, the water tank 6 is used to contain water, and the water pump 9 is used to pump the water in the water tank 6 to the connecting pipe 10, so that the water enters the humidification box 12, enters the test box 1 through the humidification nozzle 13, contacts the test object, and increases the humidity.

[0050] In this embodiment, the water supply unit is capable of supplying water to the humidifying unit and is arranged outside the test box 1. Water can be added to the humidifying box 12 without opening the test box 1, thereby avoiding water shortage in the humidifying box 12 when the test box 1 is in the test process, which affects the humidification function of the test object, and is beneficial to the humidification durability and flexibility of the test device.

[0051] In some embodiments, a water supply tank 7 is provided on the top of the water tank 6 , and a solenoid valve 8 is installed at the water supply tank 7 .

[0052] Specifically, the water adding groove 7 is the water adding channel of the water tank 6, and water is added to the water tank 6 through the water adding groove 7. The solenoid valve 8 is set to electrically control the opening and closing of the water adding groove 7. The switch of the solenoid valve 8 is connected to the control end 3 on the test box 1. The user controls the opening and closing of the solenoid valve 8 through the control end 3, and then controls the opening and closing of the water adding groove 7, so that the user can add water to the water tank 6 through the water adding groove 7 or close the water tank 6 to prevent debris from entering the water tank 6 and affecting the normal operation of the humidification structure.

[0053] In some embodiments, Figure 3As shown, the test device further includes an auxiliary structure, which includes a connected moving component and a control member 15, the control member 15 is located on the outer wall of the test box 1, and its output end passes through the side wall of the test box 1 and is fixedly connected to the moving component located in the test box 1, and the control member 15 is electrically connected to the control terminal 3 of the test box 1;

[0054] The moving assembly includes a bidirectional screw 16 and a slider 17 that are rotatably connected to the inner side wall of the test box 1. The slider 17 is sleeved on the outer periphery of the bidirectional screw 16 and is threadedly connected to the bidirectional screw 16. One end of the bidirectional screw 16 is fixedly connected to the output end of the control member 15 through a bearing 14, and the other end is rotatably connected to the side wall of the test box 1 through the bearing 14.

[0055] Among them, there are two sliders 17, which are respectively connected to the two directions of the bidirectional screw 16 with threads. The slider 17 includes a connecting part and a clamping part that are connected to each other. The connecting part is sleeved on the outer periphery of the bidirectional screw 16 and is threadedly connected to the bidirectional screw 16. The clamping part is driven by the connecting part to approach or move away from the test object on the vibration table 4.

[0056] Specifically, the control member 15 can be a driving motor, which controls the rotation and rotation direction of the bidirectional screw 16, and further controls the position of a slider 17 threadedly connected to the bidirectional screw 16 on the bidirectional screw 16. The slider 17 is provided with two sliders, which are used to contact the object to be tested located on the vibration table 4 to perform auxiliary functions such as clamping the object to be tested, wherein the clamping portion of the slider 17 is used to contact the object to be tested, and the connecting portion of the slider 17 is used to be threadedly connected to the bidirectional screw 16 and connected to the clamping portion to drive the clamping portion to approach or move away from the object to be tested.

[0057] Both ends of the bidirectional screw 16 are rotatably connected to the inner wall of the test box 1 through bearings 14, which is conducive to ensuring the smoothness and stability of the rotation of the bidirectional screw.

[0058] The bidirectional screw 16 includes two fixedly connected screws with opposite spiral directions, one slider 17 is threadedly connected to the screw in one spiral direction, and the other slider 17 is threadedly connected to the screw in the other spiral direction. The control member 15 controls the bidirectional screw 16 to rotate in the same direction. Accordingly, the two sliders 17 move in opposite directions on the bidirectional screw 16, thereby achieving the two sliders 17 approaching or moving away from each other. When the two sliders 17 approach each other, the two sliders 17 move toward the object to be tested to clamp the object to be tested. When the two sliders 17 move away from each other, the two sliders 17 both move in the direction away from the object to be tested.

[0059] It should be noted that the lengths of the two screws with opposite spiral directions on the bidirectional screw 16 are the same, that is, the movable distances of the two sliders 17 on the bidirectional screw 16 are the same, so that the distances between the two sliders 17 and the object to be tested are the same, so as to achieve uniform action on the object to be tested.

[0060] In some embodiments, the auxiliary structure further includes a cooling component, which is connected to the slider 17 and disposed close to the vibration table 4 , and is electrically connected to the control terminal 3 of the test box 1 .

[0061] Specifically, the cooling component is connected to the slider 17 and can move with the slider 17 to get closer to or farther away from the object to be tested so as to perform a cooling operation on the object to be tested. In addition, the cooling component is arranged on the slider 17 close to the vibration table 4 and can get close to the object to be tested located on the vibration table 4, thereby improving the cooling effect on the object to be tested.

[0062] In this embodiment, the setting of the cooling component can facilitate the user to control the operation of the cooling component by operating the control terminal 3 outside the test box 1 after the test object completes the high-temperature vibration test, thereby achieving efficient cooling of the test object, facilitating the user's subsequent operations on the test object after the high-temperature test, and helping to improve the test efficiency.

[0063] Exemplarily, the cooling component may be located at a side where the two sliders 17 are close to each other, or at a side where the two sliders 17 are far away from each other, or at any other position of the slider 17 that is close to the object to be tested.

[0064] In addition, the cooling component can be directly connected to the slider 17 or connected to the slider 17 via a spacing rod 19 .

[0065] In some embodiments, Figure 4As shown, the cooling component includes an electric slide rail 20, a slide rod 21 and a cooling fan 23. The electric slide rail 20 and the slide rod 21 are adapted to each other. The cooling fan 23 is fixedly connected to the slide rod 21 and is arranged toward the test object located on the vibration table 4. The electric slide rail 20 and the cooling fan 23 are both electrically connected to the control end 3 of the test box 1.

[0066] Specifically, the electric slide rail 20 is connected to the slider 17, one end of the slide rod 21 is located in the electric slide rail 20, and the other end is connected to the cooling fan 23. The cooling fan 23 can move along the electric slide rail 20 driven by the slide rod 21 to cool the object to be tested.

[0067] The electric slide rail 20 and the cooling fan 23 are both electrically connected to the control terminal 3 of the test box 1 , and a user can control the operation of the electric slide rail 20 and the cooling fan 23 by controlling the control terminal 3 outside the test box 1 .

[0068] In some embodiments, the electric slide rail 20 is located on a side of the slider 17 close to the bearing 14 and is arranged up and down;

[0069] The slide bar 21 is an L-shaped structure, one end of which is adapted to the electric slide rail 20, and the other end is connected to the cooling fan 23, and the cooling fan 23 is arranged toward the slider 17;

[0070] The slider 17 is provided with a plurality of through holes 18 , and the through holes 18 are arranged close to the vibration table 4 .

[0071] Specifically, the cooling component is located on a side of the slider 17 close to the bearing 14, that is, a side where the two sliders 17 are away from each other. The electric slide rail 20 is arranged up and down, and the slide rod 21 can drive the cooling fan 23 to slide up and down along the electric slide rod 21, that is, to slide up and down relative to the slider 17. The slide rod 21 is arranged to be an L-shaped structure, and one end thereof connected to the cooling fan 23 is arranged toward the vibration table 4, so that the cooling fan 23 is close to the vibration table 4, so as to cool down the test object located on the vibration table 4. The slider 17 is provided with a through hole 18 opposite to the cooling fan 23, and is arranged close to the vibration table 4, so that the cooling fan 23 can cool down the test object located on the side where the two sliders 17 are close to each other through the through hole 18, without affecting the humidification effect of the humidification structure located on the top of the test object on the test object.

[0072] It should be noted that there are two cooling components, which are respectively located on the side where the two sliders 17 are away from each other, and the electric slide rails 20 are arranged up and down, that is, the cooling fan 23 can move up and down relative to the slider 17 to get closer to or away from the object to be tested.

[0073] In this embodiment, the specific structure and specific position of the cooling component are further limited so that it can not only play a cooling role, but also does not affect the clamping of the slider 17 on the test object, nor does it affect the humidification effect of the humidification structure on the test object, thereby ensuring the orderly operation of each structure of the test device, which is beneficial to the practicality and application promotion performance of the test device.

[0074] In some embodiments, the cooling component also includes a cooling box 22, the cooling fan 23 is located in the cooling box 22, and is connected to the slide rod 21 through the cooling box 22. The cooling box 22 has an opening on one side facing the slider 17, and a flow groove 24 is provided on the side opposite to the opening.

[0075] Specifically, the cooling fan 23 is located in the cooling box 22, and the cooling fan 23 is connected to the slide bar 21 through the cooling box 22. The setting of the cooling box 22 can not only protect the cooling fan 23 and prevent the cooling fan 23 from being directly affected by the high temperature in the test box 1 and affecting the normal test, but also concentrate the wind generated by the operation of the cooling fan 23 at the opening of the through hole 18 facing the slider 17, so that the wind force of the cooling fan 23 through the through hole 18 to cool the object to be tested is more concentrated, which is beneficial to improving the cooling effect on the object to be tested.

[0076] A high temperature vibration test device provided in the present application can not only meet the humidification needs in high temperature vibration tests, but also assist in cooling down the test items that have completed the high temperature vibration test, which is beneficial to improving the efficiency of removing the test items in the high temperature vibration test.
