[0003] When conducting a vibration test, the product to be tested is first placed on the vibration table, and then the test box is lifted to the top of the vibration table and placed toward the vibration table.

[0036] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings and are constructed and operated in specific directions. They are only for the convenience of describing the technical solution and do not indicate that the devices or components referred to must have specific directions. Therefore, they should not be understood as limiting the present invention.

[0037] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0038] Please refer to Figure 1 The embodiment of the present application provides a three-in-one test device, which includes a base 10, a moving frame 20, a test box 30, a driving mechanism and a vibration mechanism 40.

[0039] Specifically, the base 10 has a first direction X and a second direction Y that are perpendicular to each other. A movable frame 20 is connected to the upper surface of the base 10 and is movable along the first direction X. A test chamber 30 is connected to the movable frame 20 and comprises a sealed test chamber. The bottom of the test chamber 30 has an opening that connects to the test chamber. The drive mechanism includes a first drive unit 61 and a second drive unit 62. The first drive unit 61 is used to drive the test chamber 30 to rise and fall along the second direction Y, while the second drive unit 62 is used to drive the movable frame 20 to move along the first direction X, thereby driving the movement of the test chamber 30. The vibration mechanism 40 includes a vibration source 41 and a horizontal vibration table 43 and a vertical vibration table 42 for placing the product to be tested. The vibration source 41, the horizontal vibration table 43 and the vertical vibration table 42 are arranged on the upper surface of the base 10 at intervals along the first direction X and are located on the moving path of the test box 30. The vibration source 41 is used to cause the horizontal vibration table 43 to generate horizontal vibration and the vertical vibration table 42 to generate vertical vibration, and both the horizontal vibration assembly and the vertical vibration assembly can be extended into the test space through the insertion port.

[0040] For the convenience of description, the first direction X in this embodiment refers to the length direction of the base 10. Figure 1 The second direction Y refers to the height direction of the base 10, which can be specifically Figure 1 in the Y direction.

[0041] The present application sets a vibration source 41, a horizontal vibration table 43 and a vertical vibration table 42 on the upper surface of the base 10, and the vibration source 41 can make the horizontal vibration table 43 generate horizontal vibration, and the vertical vibration table 42 generate vertical vibration. When a horizontal vibration test is required, the product is placed on the horizontal vibration table 43, and then the second driving unit 62 drives the movable frame 20 to move along the first direction X, so as to drive the test box 30 connected to the movable frame 20 to move. After the test box 30 is moved to the top of the horizontal vibration table 43, the second driving unit 62 stops driving, and then the first driving unit 61 is used to drive the test box 30 to rise and fall along the second direction Y, so that the horizontal vibration table 43 extends from the insertion port into the test space. At this time, the vibration source 41 makes the horizontal vibration table 43 generate horizontal vibration, thereby realizing a horizontal vibration test of the product to be tested; if a vertical vibration test is required, the product is placed on the vertical vibration table 42, and then the second driving unit 62 drives The movable frame 20 moves along the first direction X to drive the test box 30 connected to the movable frame 20 to move until the test box 30 is moved above the vertical vibration table 42. The second driving unit 62 stops driving, and then the first driving unit 61 is used to drive the test box 30 to rise and fall in the second direction Y, so that the vertical vibration table 42 extends from the insertion port into the test space. At this time, the vibration source 41 causes the vertical vibration table 42 to generate vertical vibration, thereby realizing a vertical vibration test of the product to be tested. If only high and low temperature and humidity and heat tests are required, the product is placed on the placement table 50, and then the second driving unit 62 drives the movable frame 20 to move along the first direction X to drive the test box 30 to move above the placement table 50. Then, the first driving unit 61 is used to drive the test box 30 to descend in the second direction Y, so that the placement table 50 extends from the insertion port into the test space, thereby realizing the high and low temperature and humidity and heat tests on the product to be tested.

[0042] That is, the three-in-one test device of the present application connects the test box 30 to the mobile frame 20, uses the first drive unit 61 to drive the mobile frame 20 to move to drive the movement of the test box 30, and simultaneously uses the second drive unit 62 to drive the test box 30 to rise and fall, thereby realizing automatic position adjustment of the test box 30, and can automatically dock with one of the horizontal vibration table 43 and the vertical vibration table 42 according to different test types, eliminating the need for manual installation, reducing labor intensity, and ensuring installation accuracy. In addition, the base 10 is provided with a horizontal vibration table 43 and a vertical vibration table 42 at the same time, and in conjunction with the test box 30 that can realize automatic movement and lifting, a variety of different types of tests such as high and low temperature, humidity and heat, horizontal vibration, and vertical vibration can be carried out simultaneously. The equipment has diversified functions and high practicality.

[0043] In addition, it should be noted that when a vibration test is not required, the vibration source 41 can be turned off, and one of the horizontal vibration table 43 or the vertical vibration table 42 can be used to support the product to be tested. At this time, the horizontal vibration table 43 or the vertical vibration table 42 only plays a supporting role. However, in order to make the operation more convenient, in one embodiment, the three-in-one test device also includes a placement table 50. The placement table 50 is provided on the upper surface of the base 10 and is located on the same horizontal line as the horizontal vibration component and the vertical vibration component. The placement table 50 is used to place the product to be tested and can be extended into the test space from the insertion port. In this way, when a vibration test is not required, the product to be tested only needs to be placed on the placement table 50 and extended into the test space from the insertion port to perform a vibration-free test.

[0044] In another embodiment, a plurality of vibration mechanisms 40 may be provided, and a plurality of independent test spaces may be separated correspondingly in the test box 30, and an insertion opening extending into the corresponding test space may be opened at the bottom of the test box 30, so that a plurality of vibration mechanisms 40 may be extended from the corresponding insertion opening into the test space for testing, thereby enabling multiple groups of tests to be performed simultaneously under the same temperature and humidity environment, which is beneficial to improving test efficiency.

[0045] In addition, multiple movable racks 20 and driving mechanisms can be provided in a one-to-one correspondence, each movable rack 20 is driven by a corresponding driving mechanism, and each movable rack 20 is provided with a test box 30, so that the corresponding driving mechanism can be used to drive the test box 30 connected to the corresponding movable rack 20 to move to the position of the horizontal vibration table 43 and the vertical vibration table 42, so that horizontal vibration and vertical vibration tests can be carried out simultaneously, which is beneficial to improving the efficiency of the test.

[0046] For example, to accurately detect test data, sensors are installed inside the box to capture test data during the test. To this end, wiring holes are provided in the side walls of the test box 30 to allow wires to be inserted and electrically connected to the corresponding sensors, thereby enabling timely transmission of the acquired test data. Furthermore, a viewing window is provided on the front of the test box 30, through which the status of the product inside the test box 30 can be observed in a timely manner.

[0047] Exemplarily, vibration source 41 is used to generate vibrations in different directions for horizontal vibration table 43 and vertical vibration table 42. For example, when vibration source 41 is connected to horizontal vibration table 43, horizontal vibration table 43 can generate only horizontal vibrations, while when vibration source 41 is connected to vertical vibration table 42, vertical vibration table 42 can generate only vertical vibrations. To this end, vibration source 41 can adopt the specific structure described in the following embodiments, or can adopt a vibration component in the prior art that can generate unidirectional vibrations for horizontal vibration table 43 and vertical vibration table 42, without limitation.

[0048] Specifically, the vibration source 41 includes a base 411 and a vibration generating element 412. The base 411 is fixed on the upper surface of the base 10 and is located on the same horizontal line as the horizontal vibration table 43 and the vertical vibration table 42. The base 411 is provided with a mounting position, and the vibration generating element 412 can be flipped and installed in the mounting position. The top of the vibration generating element 412 has a connecting end, which is used to be connected to the horizontal vibration table 43 or the vertical vibration table 42 so that the vibration of the vibration generating element 412 is transmitted to the horizontal vibration table 43 or the vertical vibration table 42. That is to say, the vibration generating element 412 can be flipped relative to the base 411. If a horizontal vibration test is required, the vibration generating element 412 is flipped to a horizontal state, and the vibration generating element 412 is connected to the horizontal vibration table 43. At this time, the vibration generated by the vibration generating element 412 is only in the horizontal direction; if a vertical vibration test is required, the vibration generating element 412 is flipped to a vertical state, and the vibration generating element 412 is connected to the vertical vibration table 42. At this time, the vibration generated by the vibration generating element 412 is only in the vertical direction, so that corresponding vibration can be provided according to different test types.

[0049] In actual application, the vibration generating member 412 can be connected to the inner wall of the base 411 by a connecting shaft provided on its outer side, so that the vibration generating member 412 can be flipped relative to the base 411. It should be noted that after the vibration generating member 412 is flipped into place, the connecting shaft needs to be locked using a locking member to prevent it from flipping randomly when generating vibration. As for how to use the locking member to lock, reference can be made to the existing technology and this will not be described in detail. In addition, the vibration generating member 412 can generate a vibration member that can generate unidirectional vibration in the existing technology, and this is not limited to this.

[0050] Please refer to Figure 2 and Figure 3In one embodiment, the first drive unit 61 includes a drive assembly 612 and a plurality of rotating rods 611. The rotating rods 611 are rotatably connected to the lifting frame along the second direction Y and are located outside the test chamber 30. Connecting blocks 30a extend outwardly from the outer surface of the test chamber 30 and are slidably connected to the rotating rods 611. The drive assembly 612 is disposed on the movable frame 20 and is configured to rotate the rotating rods 611, thereby causing the test chamber 30 to be raised or lowered along the second direction Y. Specifically, when the test chamber 30 needs to be raised or lowered along the second direction Y, the drive assembly 612 drives the rotating rods 611 to rotate. Since the test chamber 30 is connected to the rotating rods 611 via the connecting blocks 30a extending outwardly from its outer surface, when the rotating rods 611 rotate, the connecting blocks 30a are driven to move along the rotating rods 611, thereby causing the test chamber 30 to be raised or lowered. This automatically adjusts the height of the test chamber 30, eliminating the need for manual adjustment and reducing labor intensity.

[0051] In actual application, the rotating rod 611 is a screw rod, and the connecting block 30a is connected to the screw rod by a threaded connection, and the rotation of the screw rod is used to drive the movement of the connecting block 30a. Figure 4 To precisely control the height of the test chamber 30, a circular sheet 6126 is provided on the rotating rod 611 near the top of the movable frame 20. A slot-shaped photoelectric sensor 6125 is also provided on the top of the movable frame 20 to detect the number of rotations of the circular sheet 6126. By detecting the number of rotations of the circular sheet 6126, the slot-shaped photoelectric sensor can determine the number of rotations of the rotating rod 611, thereby calculating the height of the test chamber 30 along the second direction Y. The above is merely an example and is not intended to be limiting.

[0052] Specifically, the driving assembly 612 includes a power part 6121, a first rotating shaft 6122 and two second rotating shafts 6123. The first rotating shaft 6122 is rotatably connected to the top of the movable frame 20 along the first direction X. The two second rotating shafts 6123 are symmetrically arranged on the outside of the two ends of the first rotating shaft 6122 and extend in a direction perpendicular to the first rotating shaft 6122. The end of the first rotating shaft 6122 is transmission-connected to the second rotating shaft 6123. A first transmission tooth 6124 is installed at one end of the rotating rod 611 close to the second rotating shaft 6123, and a second transmission tooth matching the first transmission tooth 6124 is provided on the second rotating shaft 6123.

[0053] In actual application, the power part 6121 can adopt a servo motor. When the test box 30 needs to be docked with the horizontal vibration table 43, the vertical vibration table 42 or the placement table 50, the first rotating shaft 6122 is driven to rotate by the servo motor. Since the second rotating shaft 6123 is connected to the first rotating shaft 6122, the second rotating shaft 6123 is driven to rotate, thereby driving the second transmission tooth to rotate, so that the first transmission tooth 6124 matched with the second transmission tooth rotates, thereby driving the rotating rod 611 to rotate, and realizing the control of the automatic lifting and lowering of the test box 30 along the second direction Y. There is no need for manual installation, which is conducive to reducing labor intensity.

[0054] Please refer to Figure 2 In one embodiment, the second driving unit 62 includes a track 621, a walking wheel 623 and a driving member 622. The track 621 is arranged on the upper surface of the base 10 along the first direction X and is located on the outside of the placement table 50. The end of the mobile frame 20 close to the base 10 is rotatably connected to the walking wheel 623, and the walking wheel 623 is rollingly connected to the track 621. The driving member 622 is installed at the end of the mobile frame 20 close to the base 10 and is located on the outside of the walking wheel 623. The output end of the driving member 622 is connected to the walking wheel 623 for driving the walking wheel 623 to move on the track 621. That is to say, when the test box 30 needs to be driven to move, the driving member 622 drives the walking wheel 623 to rotate. Since the walking wheel 623 is rollingly connected to the track 621, and the walking wheel 623 is installed at one end of the mobile frame 20 close to the base 10, the mobile frame 20 is driven to move, and then the test box 30 is driven to move, thereby controlling the automatic movement of the test box 30 without manual operation.

[0055] It should be noted that, in order to maintain smooth movement, the four corners of the mobile frame 20 near one end of the base 10 are each equipped with running wheels 623, each of which is driven by a driver 622. The driver 622 can be a servo motor, or a power component capable of driving the running wheels 623 to rotate in the prior art, without limitation. In addition, anti-slip blocks 624 are provided at both ends of the track 621 to restrict the running wheels 623 from falling off the track 621 during movement.

[0056] Please refer to Figure 5 and Figure 6In one embodiment, the vertical vibration platform 42 includes a first support plate 422 and a first support frame 421 movable along a first direction X. The first support frame 421 is surrounded by a first placement position and has a first insertion opening on the side of the first support frame 421 facing the vibration generating element 412, which is connected to the first placement position. The first support plate 422 is fixed to the top of the first support frame 421 and is located above the first placement position. When the vibration generating element 412 is stored in the first placement position and flipped to a vertical position, the connection end of the vibration generating element 412 is connected to the first support plate 422.

[0057] When a vertical vibration test is required, the vibration generating member 412 is first flipped to a vertical state, and then the first support frame 421 is pushed in a direction close to the vibration generating member 412 so that the vibration generating member 412 is stored in the first installation position. At this time, the connection end of the vibration generating member 412 is connected to the first support plate 422, and the product to be tested is placed on the first support plate 422, so that the vibration generated by the vibration generating member 412 is transmitted to the first support plate 422, and then the product on the first support plate 422 generates vertical vibration, thereby completing the vertical vibration test inside the test box 30.

[0058] In actual application, the connection between the vibration generating member 412 and the first support plate 422 can be achieved by plugging in, that is: a plug-in hole 422a is set in the middle of the first support plate 422, and the plug-in hole 422a corresponds to the connection end of the vibration generating member 412. When conducting a vertical vibration test, the first support frame 421 is pushed to allow the vibration generating member 412 to be stored in the first installation position, and then the first support plate 422 is installed on the top of the first support frame 421. At this time, the connection end of the vibration generating member 412 is plugged into the plug-in hole 422a, thereby realizing the connection between the vibration generating member 412 and the first support plate 422, ensuring the effective transmission of vibration.

[0059] Specifically, a first slide rail 70 is provided on the upper surface of the base 10, and a first pulley 423 is connected to one end of the first support frame 421 close to the base 10, and the first pulley 423 is slidably connected to the first slide rail 70. In this way, the first support frame 421 can slide on the base 10, with a simple structure and easy operation.

[0060] Please refer to Figure 5 and Figure 6In one embodiment, the horizontal vibration table 43 includes a support platform 433 and a second support frame 431 movable along a first direction X. The second support platform 433 is disposed on one side of the base 411. After the vibration generating member 412 is flipped to a horizontal position, the support platform 433 is connected to the connection end of the vibration generating member 412. The second support frame 431 is surrounded by a second placement position and has a second push-in opening on the side of the second support frame 431 facing the vibration generating member 412, which is connected to the second placement position. The second support plate 432 is fixed to the top of the second support frame 431 and is located above the second placement position. The second support plate 432 has a second push-in opening. When the support platform 433 is stored in the second installation position, the support surface of the support platform 433 is exposed from the extension opening.

[0061] When a horizontal vibration test is required, the vibration generating member 412 is first flipped to a horizontal state, and then the second support frame 431 is pushed toward the support platform 433 so that the support platform 433 is stored in the second installation position, and then the second support plate 432 is fixed on the top of the second support frame 431. At this time, the supporting surface of the support platform 433 is exposed from the extension port, and the product to be tested is placed on the supporting surface of the support platform 433, so that after the vibration transmitted by the vibration generating member 412 reaches the supporting surface of the support platform 433, the product to be tested generates vertical vibration, thereby completing the horizontal vibration test inside the test box 30.

[0062] Specifically, a second slide rail 80 is provided on the upper surface of the base 10, and a second pulley 434 is connected to one end of the second support frame 431 close to the base 10, and the second pulley 434 is slidably connected to the second slide rail 80. In this way, the second support frame 431 can slide on the base 10, with a simple structure and easy operation.

[0063] Please refer to Figure 7 In one embodiment, a cooling mechanism is further included, comprising a water inlet pipe 90, a water outlet pipe 100, and a drag chain 110. One end of the water inlet pipe 90 is connected to the water inlet of the circulating refrigeration system inside the test chamber 30, and one end of the water outlet pipe 100 is connected to the water outlet of the circulating refrigeration system. The water inlet pipe 90 and the water outlet pipe 100 are at least partially housed side by side within the drag chain 110. Both the water inlet pipe 90 and the water outlet pipe 100 are made of soft material.

[0064] In actual applications, the test chamber 30 is equipped with a refrigeration cycle system to regulate the temperature and humidity inside the test chamber 30, thereby simulating different temperature and humidity environments for testing. The refrigeration cycle system typically uses a compressor, condenser, evaporator, and expansion valve, etc. For details, please refer to the existing technology and are not limited to this. The water supply for the circulating refrigeration system is provided by the water inlet pipe 90 and the water outlet pipe 100. However, when the test chamber 30 moves, the water inlet pipe 90 and the water outlet pipe 100 will also move with it, and thus may be damaged by the pulling of the water inlet pipe 90 and the water outlet pipe 100. To this end, this embodiment uses a drag chain 110 to wrap the water inlet pipe 90 and the water outlet pipe 100 inside it, and the water inlet pipe 90 and the water outlet pipe 100 are both made of soft materials, so that when the test box 30 moves, only the drag chain 110 pulls the water inlet pipe 90 and the water outlet pipe 100 to move, thereby effectively solving the problem of damage caused by repeated wear and tear of the water inlet pipe 90 and the water outlet pipe 100 against the base 10 due to pulling.

[0065] To facilitate understanding of the working principle of this application, the following description will be made using a vertical vibration test as an example. The horizontal vibration test and the no-vibration test can refer to the test method of the horizontal vibration test, which will not be described in detail. The specific steps of the vertical vibration test are as follows:

[0066] Vertical vibration test:

[0067] S1. Flip the vibration generating member 412 to a vertical position, then push the first support frame 421 toward the support platform 433 so that the base 411 and the vibration generating member 412 are stored in the first support frame 421. Then, fix the first support plate 422 to the top of the first support frame 421. At this time, the connecting end of the vibration generating member 412 is inserted into the plug hole 422a to achieve the connection between the vibration generating member 412 and the first support plate 422. Then, place the product to be tested on the second support plate 432.

[0068] S2. The power member 6121 drives the first rotating shaft 6122 to rotate, thereby driving the second rotating shaft 6123 to rotate, thereby transmitting power to the rotating rod 611. Since the connecting block 30a is slidably connected to the rotating rod 611, the connecting block 30a is driven to move upward on the rotating rod 611, and the test box 30 is also driven to move upward, so that the test box 30 is positioned above the first support plate 422. At this time, the power member 6121 stops working;

[0069] S3, the driving member 622 drives the walking wheel 623 to rotate. Since the walking wheel 623 is connected to the track 621 in a rolling manner, and the walking wheel 623 is installed at one end of the mobile frame 20 close to the base 10, the mobile frame 20 is driven to move, thereby driving the test box 30 to move until it moves to the position just above the first support plate 422 of the test box 30, and the driving member 622 stops working (refer to Figure 8 );

[0070] S4, control the power member 6121 to drive the first rotating shaft 6122 to flip, so as to drive the second rotating shaft 6123 to rotate in the opposite direction, so that the test box 30 is driven to move downward, so that the first support plate 422 enters the interior of the test box 30 from the insertion port, and the first support plate 422 seals the insertion port (refer to Figure 9 );

[0071] S5 , starting the vibration generating member 412 to transmit vibration to the first support plate 422 , so that the product on the first support plate 422 generates vertical vibration, thereby performing a vertical vibration test inside the test box 30 .

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
