Description

Technical Field

[0001] The present invention belongs to the technical field of test tooling, and particularly relates to a fatigue test tooling for router connectors. Background Art

[0002] The fatigue test of router plugs is a durability evaluation method for router plugs. This test aims to simulate various plugging and unplugging actions and environmental factors experienced by the plugs during actual use, so as to evaluate the stability and reliability of router connectors during long-term use.

[0003] The existing fatigue test tooling for router connectors can conveniently adjust the plug spacing through a horizontally moving cylinder to adapt to different specifications of routers. During the reciprocating plugging and unplugging actions of the plugs, the attraction state of the electro-controlled magnetic absorption block is controlled by the on-off of the circuit between the plugs and the routers, and the plugs corresponding to the open-circuit connectors are immediately braked, which is convenient for the staff to identify and replace.

[0004] Although the existing test tooling can quickly judge the connection state between the plugs and the router connectors and quickly brake the plugs, the whole machine needs to be shut down when replacing the plugs. This is not only cumbersome and laborious, time-consuming and laborious, but also interrupts the test work of the plugs in the normal working state, thus affecting the overall test efficiency and work progress of the test tooling.

[0005] Therefore, in view of the above current situation, there is an urgent need to develop a fatigue test tooling for router connectors to overcome the deficiencies in current practical applications. Summary of the Invention

[0014] As a further technical solution of the present invention, the testing mechanism includes a left clamping plate, a right clamping plate, a second slider, a mounting block and a clamping component. The left clamping plate and the right clamping plate are distributed on the left and right sides of the connecting component.

[0019] Adopting the above technical solutions, the present invention has the following beneficial effects:

[0020] The reciprocating mechanism drives the fixed component to move on the secondary sliding seat, and through the connecting component, the testing mechanism and the testing plug reciprocate on the primary sliding seat, realizing the insertion and extraction of the router connector. The testing host senses the electrical signal between the testing plug and the router, thereby realizing the fatigue test of the router connector;

[0021] If the testing host fails to sense the electrical signal between a certain testing plug and the router, the testing host drives the control mechanism to which the testing plug belongs to work. The control mechanism limits and fixes the testing mechanism and separates the connecting component from the testing mechanism, so that the reciprocating mechanism can only drive the fixed component, the connecting component, and other testing plugs to which the testing plug belongs to continue to reciprocate. This not only facilitates the staff to replace the testing plug, ensures the continuity of the testing work, improves the testing efficiency of the testing tooling, but also avoids the shutdown of the entire testing tooling due to the replacement of the testing plug, enabling other normally working testing plugs to continue the testing work following the reciprocating mechanism, greatly reducing the overall testing time of the router connector, and further improving the testing efficiency of the testing tooling;

[0022] After the replacement is completed, the control mechanism returns to its initial state, and the reciprocating mechanism drives the connecting component and the testing mechanism to be engaged again and continue the testing; if the replaced testing plug is combined with the router connector but no electrical signal is generated, the testing host drives the control mechanism to limit and fix the testing mechanism again, facilitating the staff to judge the connector failure and obtain the insertion and extraction times based on the reciprocating times, efficiently completing the fatigue test, and improving the data accuracy, tooling flexibility, and adaptability.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0040] The present invention will be further explained and described below in conjunction with specific implementation manners.

[0041] As Figures 1 to 10As shown in the figure, a fatigue test tooling for a router connector provided in this embodiment includes a test bench 100. On the front and back sides of the test bench 100, there are respectively a plug platform 101 and an installation platform 102 for installing the router. On the installation platform 102, there are distributed fixed guide grooves 103 for fixing the left and right sides and the front side of the router. On one side of the installation platform 102 close to the plug platform 101, there is a fixed boss 104 for fixing the rear side of the router. On the plug platform 101, there are arranged a plurality of main sliders 300, and a reciprocating mechanism 200 is installed on the plug platform 101. It also includes:

[0042] A test mechanism 500, which is slidably installed at one end of the main slider 300 and intermittently cooperates with a control mechanism 700 installed on the main slider 300. One end of the test mechanism 500 is fixed with a test plug 600. Both the test plug 600 and the router are connected to a test host. The test host can sense the electrical signal between the test plug 600 and the router, so as to judge the connection state between the test plug 600 and the router connector;

[0043] A fixed connection mechanism 400, which includes a secondary slider 410, a fixing component 420 and a connection component 430. The secondary slider 410 is fixed to the other end of the main slider 300 through a slider bracket 411. The secondary slider 410 is parallel to the main slider 300. The fixing component 420 is slidably installed on the secondary slider 410 and is located in the middle of the test mechanism 500. The fixing component 420 is connected to the reciprocating mechanism 200. On both sides of the fixing component 420, there are installed connection components 430 that are engaged with the test mechanism 500.

[0044] In the initial state, one end of the control mechanism 700 is hidden in the main slider 300, and the limit and fixation of the test mechanism 500 are released. The test mechanism 500 can slide freely on the main slider 300. At the same time, the connection components 430 on both sides of the fixing component 420 are all engaged with the test mechanism 500;

[0045] The reciprocating mechanism 200 drives the fixing component 420 to reciprocate on the secondary slider 410. The fixing component 420 drives the test mechanism 500 to reciprocate on the main slider 300 through the connection component 430. The test mechanism 500 drives the test plug 600 to reciprocate, so that the test plug 600 can realize the reciprocating plugging and unplugging of the router connector. The test host senses the electrical signal between the test plug 600 and the router, so as to realize the fatigue test of the router connector;

[0046] When the test host fails to sense the electrical signal between a certain test plug 600 and the router, the test host can drive the control mechanism 700 to which the test plug 600 belongs to work. The control mechanism 700 positions and fixes the test mechanism 500 to which the test plug 600 belongs. At the same time, the limiting force of the control mechanism 700 on the test mechanism 500 can drive the connection component 430 to separate from the test mechanism 500, so that the reciprocating mechanism 200 can only drive the fixing component 420, the connection component 430 to which the test plug 600 belongs, and other test plugs 600 to continue to reciprocate, while the test mechanism 500 to which the test plug 600 belongs remains stationary on the main slide 300. This not only facilitates the replacement of the test plug 600 by the staff, ensures the continuity of the test work, improves the test efficiency of the test tooling, but also avoids the shutdown of the entire test tooling due to the replacement of the test plug 600, enabling other normally working test plugs 600 to continue the test work following the reciprocating mechanism 200, greatly reducing the overall test time of the router connector and further improving the test efficiency of the test tooling;

[0047] After the replacement of the test plug 600 is completed, the control mechanism 700 to which it belongs returns to the initial state. The reciprocating mechanism 200 can drive the connection component 430 to which the test plug 600 belongs to engage with the test mechanism 500 again, and drive the test mechanism 500 and the test plug 600 to continue to complete the fatigue test of the router connector. At the same time, when the replaced test plug 600 is combined with the router connector and no electrical signal is generated, the test host drives the control mechanism 700 to work again at this time, so that the control mechanism 700 positions and fixes the test mechanism 500 that has moved back again. This can facilitate the staff to quickly determine that the connector of the router is faulty, and combined with the reciprocating times of the test mechanism 500, quickly obtain the plugging and unplugging times of the connector on the router, thus efficiently completing the fatigue test work of the connector, improving the accuracy of the fatigue test data of the router connector, and improving the flexibility and adaptability of the test tooling.

[0048] In a preferred embodiment, a photoelectric sensor is further provided on one side of the test mechanism 500. The photoelectric sensor is used to sense and count the reciprocating times of the test mechanism 500, and thus sense and count the plugging and unplugging times of the test plug 600, facilitating the staff to collect and count the fatigue test data of the router connector, ensuring the accuracy of the test data, and improving the test efficiency of the test tooling.

[0049] As Figures 3 to 9As shown in the figure, as a preferred embodiment of the present invention, the connection component 430 includes a connection block 431, a connection frame 432, a sliding column 433, a clamping component 434, and a second spring 435. The connection block 431 is installed on the front and back sides of the fixing component 420. One end of the connection block 431 is fixed with a connection frame 432. The connection frames 432 are distributed on both sides of the fixing component 420 and are located in the middle of the testing mechanism 500. A sliding column 433 is vertically and slidably installed on the connection frame 432. One end of the sliding column 433 is fixed with a clamping component 434. A second spring 435 is installed between one end of the clamping component 434 and the connection frame 432. The other end of the clamping component 434 is engaged with the testing mechanism 500.

[0050] The connection block 431 preferably adopts a T-shaped block structure. The connection block 431 and the connection frame 432 are preferably manufactured by an integral molding process. The clamping component 434 preferably adopts a trapezoidal block structure. The end faces of the clamping component 434 engaged with the testing mechanism 500 are inclined end faces, which facilitates the clamping component 434 to quickly engage and disengage with the testing mechanism 500.

[0051] The elastic force of the second spring 435 is greater than the insertion and extraction resistance between the test plug 600 and the router connector, and this elastic force is less than the limiting force of the control mechanism 700 on the testing mechanism 500. In this way, during the process of the test plug 600 reciprocatingly inserting and extracting on the router connector, it can be ensured that the clamping component 434 is always engaged with the testing mechanism 500, thereby ensuring that the testing mechanism 500 can reciprocate with the reciprocating mechanism 200. At the same time, when the control mechanism 700 limits the testing mechanism 500, it can be ensured that the testing mechanism 500 can be separated from the clamping component 434, and it is ensured that during the normal reciprocating movement of the clamping component 434, it cannot drive the testing mechanism 500 to reciprocate, which is convenient for the staff to replace the test plug 600 on the testing mechanism 500 or quickly complete the fatigue test work on a single router connector.

[0052] In the initial state, the second spring 435 drives the sliding column 433 to slide upward through its own elastic force. The sliding column 433 drives the clamping component 434 to move upward, so that the clamping component 434 completes the engagement with the testing mechanism 500. When the reciprocating mechanism 200 drives the fixing component 420 to reciprocate, the fixing component 420 drives the connection block 431 and the connection frame 432 to move. The connection frame 432 drives the testing mechanism 500 to move through the sliding column 433 and the clamping component 434. The testing mechanism 500 drives the test plug 600 to reciprocate and completes the reciprocating insertion and extraction of the router connector. The test host senses the electrical signal between the test plug 600 and the router, thereby realizing the fatigue test of the router connector;

[0053] When the control mechanism 700 positions and fixes the test mechanism 500, since the limiting force of the control mechanism 700 on the test mechanism 500 is greater than the elastic force of the second spring 435, the test mechanism 500 is in a static state at this time. The reciprocating mechanism 200 drives the engaging part 434 to separate from the test mechanism 500 and squeezes the second spring 435, which facilitates the staff to replace the test plug 600 on the test mechanism 500, improves the accuracy of test data, and improves the working efficiency of the test tooling.

[0054] As Figures 3 to 9 shown, as a preferred embodiment of the present invention, the fixing component 420 includes a lower clamping block 421, an upper clamping block 422, a first spring 423, and a stud 424. The upper clamping block 422 and the lower clamping block 421 are distributed on both sides of the reciprocating mechanism 200, and the upper clamping block 422 and the lower clamping block 421 are fixedly connected to the reciprocating mechanism 200 through the stud 424. A first spring 423 is installed between the upper clamping block 422 and the lower clamping block 421, and connecting grooves 425 for installing the connecting block 431 are formed on the end faces of the upper clamping block 422 and the lower clamping block 421 that are close to each other. The lower clamping block 421 is slidably installed on the secondary sliding seat 410.

[0055] The stud 424 not only connects the upper clamping block 422 and the lower clamping block 421 into a whole and fixedly connects them to the reciprocating mechanism 200 in a manner of cooperating with the first spring 423, so that the reciprocating mechanism 200 can drive the upper clamping block 422 and the lower clamping block 421 to reciprocate synchronously, but also can drive the upper clamping block 422 and the lower clamping block 421 to separate from the reciprocating mechanism 200, thereby changing the positions of the upper clamping block 422 and the lower clamping block 421, and further changing the positions of the test mechanism 500 and the test plug 600, so that the test plug 600 can effectively complete the plugging and unplugging work of the router connector, meet the effective fatigue test of the test tooling for routers of different specifications or types, and improve the flexibility and applicability of the test tooling;

[0056] The reciprocating mechanism 200 drives the upper clamping block 422 and the lower clamping block 421 to reciprocate synchronously. The upper clamping block 422 and the lower clamping block 421 drive the connecting blocks 431 distributed on both sides of them to reciprocate, thereby driving the test plug 600 to reciprocate and complete the reciprocating plugging and unplugging of the router connector, so as to test the fatigue data of the router connector and improve the test efficiency of the test tooling.

[0057] In a preferred embodiment, the design of the first spring 423 is such that during the process of the stud 424 releasing the connection state between the upper clamping block 422 and the lower clamping block 421 and the reciprocating mechanism 200, the first spring 423 can help the upper clamping block 422 and the lower clamping block 421 move away from each other by releasing its own elastic force, so that the upper clamping block 422 and the lower clamping block 421 can freely adjust their positions on the reciprocating mechanism 200.

[0058] As Figures 3 to 9 shown, as a preferred embodiment of the present invention, the testing mechanism 500 includes a left clamping plate 510, a right clamping plate 520, a second slider 530, a mounting block 540 and an engaging component 550. The left clamping plate 510 and the right clamping plate 520 are distributed on the left and right sides of the connecting component 430, the second slider 530 and the mounting block 540 are distributed on the front and rear sides of the connecting component 430. The second slider 530 and the mounting block 540 are respectively installed at the front and rear ends of the left clamping plate 510 and the right clamping plate 520. The bottom of the second slider 530 is slidably connected to the main slide base 300 and is intermittently matched with the control mechanism 700. A testing plug 600 is fixed to one side of the mounting block 540. Both ends of the engaging component 550 are fixedly connected to the left clamping plate 510 and the right clamping plate 520 respectively and are matched with the engaging part 434.

[0059] The engaging component 550 includes a left engaging block 551, a guide post 552, a right engaging block 553, a fitting hole 554 and a clamping groove 555. The left engaging block 551 is vertically fixed to the inner side of the left clamping plate 510, the right engaging block 553 is vertically fixed to the inner side of the right clamping plate 520. A guide post 552 is fixed to the left engaging block 551, and the guide post 552 is slidably matched with the fitting hole 554 opened on the right engaging block 553. And clamping grooves 555 for cooperating with the engaging part 434 are opened at the bottoms of both the left engaging block 551 and the right engaging block 553.

[0060] In the initial state, the second spring 435 drives the engaging part 434 to move upward through its own elastic force. The engaging part 434 is respectively engaged with the clamping grooves 555 on the left engaging block 551 and the right engaging block 553 by moving upward, so that the left engaging block 551 and the right engaging block 553 can be connected to the engaging part 434 as a whole. When the reciprocating mechanism 200 drives the engaging part 434 to reciprocate, the engaging part 434 drives the left clamping plate 510 and the right clamping plate 520 to reciprocate synchronously through the left engaging block 551 and the right engaging block 553. The left clamping plate 510 and the right clamping plate 520 drive the second slider 530 and the mounting block 540 to reciprocate. The mounting block 540 drives the testing plug 600 to reciprocate and complete the reciprocating insertion and extraction of the router connector. The testing host senses the electrical signal between the testing plug 600 and the router, so as to realize the fatigue test of the router connector;

[0061] When the test host fails to sense the electrical signal between a certain test plug 600 and the router, the test host can drive the control mechanism 700 to which the test plug 600 belongs to work. The control mechanism 700 positions and fixes the test mechanism 500 to which the test plug 600 belongs. The control mechanism 700 can position and fix the second slider 530 by rotating, so that the second slider 530 remains stationary on the main slider 300. The second slider 530 can drive the left clamping block 551 and the right clamping block 553 to be stationary synchronously through the left clamping plate 510 and the right clamping plate 520. Since the limiting force of the control mechanism 700 on the second slider 530 is greater than the elastic force of the second spring 435, during the process of the reciprocating mechanism 200 driving the engaging member 434 to reciprocate, the engaging member 434 can intermittently cooperate with and separate from the card slots 555 on the left clamping block 551 and the right clamping block 553. At the same time, at this time, the reciprocating mechanism 200 can only drive the fixing component 420, the connecting component 430 to which the test plug 600 belongs, and other test plugs 600 to continue to reciprocate, while the second slider 530 to which the test plug 600 belongs remains stationary on the main slider 300. This can not only facilitate the staff to replace the test plug 600, ensure the continuity of the test work, improve the test efficiency of the test fixture, but also avoid the entire test fixture from shutting down due to the replacement of the test plug 600, so that other normally working test plugs 600 can continue the test work following the reciprocating mechanism 200.

[0062] In a preferred embodiment, the card slot 555 adopts a groove structure adapted to the engaging member 434, and preferably adopts a trapezoidal groove structure, which can facilitate the quick separation and quick cooperation with the engaging member 434.

[0063] Such as Figure 2 、 Figure 5 、 Figure 10 And Figure 11 As shown, as a preferred embodiment of the present invention, an inclined guide table 310 is provided at one end of the main slider 300 away from the router. Rotation grooves 320 are distributed on the inclined end surface of the inclined guide table 310. A through hole 330 penetrating the rotation grooves 320 is vertically provided on the main slider 300. Both the rotation grooves 320 and the through hole 330 are used for installing the control mechanism 700. And a blocking block is fixed at one end of the main slider 300 away from the router. The blocking block can effectively position and fix the second slider 530 in cooperation with the control mechanism 700, so that it stably remains stationary between the blocking block and the control mechanism 700, facilitating the staff to quickly replace the test plug 600, improving the test efficiency of the test fixture, and at the same time improving the stability of the overall structure of the test fixture.

[0064] Such as Figure 2 、 Figure 5 、Figure 10 and Figure 11 As shown in Figure 11 , as a preferred embodiment of the present invention, the control mechanism 700 includes a motor bracket 710, a driving motor 720, a first gear 730, a second gear 740, a control shaft 750, and a control board 760. The motor bracket 710 is fixed to one side of the main slide 300. The driving motor 720 is mounted on the motor bracket 710. The first gear 730 is mounted on the output end of the driving motor 720. The first gear 730 meshes with the second gear 740 fixed to one end of the control shaft 750. The control shaft 750 is rotatably mounted in the through hole 330. The control shaft 750 is fixedly connected to the control board 760 mounted in the rotating groove 320.

[0065] In the initial state, the control board 760 is hidden in the rotating groove 320 and does not interfere with the normal sliding of the second slider 530. When the test host fails to sense the electrical signal between a certain test plug 600 and the router, the test host can drive the control mechanism 700 to which the test plug 600 belongs to work. The driving motor 720 drives the first gear 730 to rotate. The first gear 730 drives the control shaft 750 to rotate through the second gear 740. The control shaft 750 drives the control board 760 to rotate out of the rotating groove 320, so that the control board 760 contacts one side of the second slider 530, and the second slider 530 is limited and fixed, so that the second slider 530 to which the test plug 600 belongs stops on the main slide 300.

[0066] In a preferred embodiment, the design of the rotating groove 320 controls the rotation angle of the control board 760, so that the control board 760 can only rotate to a position perpendicular to the main slide 300, that is, parallel to the side wall of the second slider 530.

[0067] As Figure 2 , Figure 7 , Figure 8 and Figure 12 As shown in Figure 2 , Figure 7 , Figure 8 and Figure 12 , as a preferred embodiment of the present invention, the reciprocating mechanism 200 includes a reciprocating motor 210, a motor bracket 220, a main shaft 230, a rocker 240, a push rod 250, a reciprocating roller 260, a first slider 270, and a side bracket 280. The reciprocating motor 210 is fixed to the plug platform 101 through the motor bracket 220. The main shaft 230 is fixed to the output end of the reciprocating motor 210. The rocker 240 is mounted on the main shaft 230. The side brackets 280 are symmetrically fixed to the left and right ends of the plug platform 101. A slider is horizontally slidably mounted on the side bracket 280. The two ends of the reciprocating roller 260 are respectively fixed to the two sliders, and the reciprocating roller 260 is located between the upper clamping block 422 and the lower clamping block 421 and is connected to both of them. The two ends of the push rod 250 are respectively rotatably connected to the rocker 240 and one end of the reciprocating roller 260.

[0068] The reciprocating motor 210 drives the main shaft 230 to rotate. The main shaft 230 drives the rocker 240 to rotate. The rocker 240 drives the reciprocating roller 260 and the slider to reciprocate through the push rod 250. The reciprocating roller 260 drives the connecting component 430 to reciprocate through the upper clamping block 422 and the lower clamping block 421, so that the connecting component 430 can drive the test plug 600 to reciprocate through the test mechanism 500, and complete the reciprocating insertion and extraction of the router connector, thereby realizing the fatigue test of the router connector.

[0069] The working principle of the present invention is:

[0070] In the initial state, the control board 760 is hidden in the rotating groove 320 and does not interfere with the normal sliding of the second slider 530. The limit and fixation of the second slider 530 are released, and the second slider 530 can slide freely on the main slide base 300. The second spring 435 drives the engaging part 434 to move upward through its own elastic force. The engaging part 434 is engaged with the card slots 555 on the left clamping block 551 and the right clamping block 553 by moving upward, so that the left clamping block 551 and the right clamping block 553 can be connected to the engaging part 434 as a whole;

[0071] The reciprocating motor 210 drives the main shaft 230 to rotate. The main shaft 230 drives the rocker 240 to rotate. The rocker 240 drives the reciprocating roller 260 and the slider to reciprocate through the push rod 250. The reciprocating roller 260 drives the upper clamping block 422 and the lower clamping block 421 to reciprocate. The upper clamping block 422 and the lower clamping block 421 drive the connecting blocks 431 distributed on both sides of them to reciprocate. The connecting blocks 431 drive the engaging part 434 to reciprocate through the connecting frame 432. The engaging part 434 drives the left clamping plate 510 and the right clamping plate 520 to reciprocate synchronously through the left clamping block 551 and the right clamping block 553. The left clamping plate 510 and the right clamping plate 520 drive the second slider 530 and the mounting block 540 to reciprocate. The mounting block 540 drives the test plug 600 to reciprocate and complete the reciprocating insertion and extraction of the router connector. The test host senses the electrical signal between the test plug 600 and the router, thereby realizing the fatigue test of the router connector;

[0072] When the test host fails to sense the electrical signal between a certain test plug 600 and the router, the test host can drive the control mechanism 700 to which the test plug 600 belongs to work, drive the motor 720 to drive the first gear 730 to rotate, the first gear 730 drives the control shaft 750 to rotate through the second gear 740, and the control shaft 750 drives the control board 760 to rotate outside the rotating groove 320, so that the control board 760 contacts one side of the second slider 530, and completes the limiting and fixing of the second slider 530, so that the second slider 530 is stationary on the main slide 300. The second slider 530 can drive the left clamping block 551 and the right clamping block 553 to be stationary synchronously through the left clamping plate 510 and the right clamping plate 520. Since the limiting force of the control mechanism 700 on the second slider 530 is greater than the elastic force of the second spring 435, during the process of the reciprocating mechanism 200 driving the engaging member 434 to reciprocate, the engaging member 434 can intermittently cooperate with and separate from the card slots 555 on the left clamping block 551 and the right clamping block 553. At the same time, at this time, the reciprocating mechanism 200 can only drive the fixing component 420, the connecting component 430 to which the test plug 600 belongs, and other test plugs 600 to continue to reciprocate, while the second slider 530 to which the test plug 600 belongs is stationary on the main slide 300. This can not only facilitate the staff to replace the test plug 600, ensure the continuity of the test work, improve the test efficiency of the test tooling, but also avoid the entire test tooling from stopping due to the replacement of the test plug 600, so that other normally working test plugs 600 can continue the test work following the reciprocating mechanism 200;

[0073] After the test plug 600 is replaced, the control mechanism 700 to which it belongs returns to the initial state. The reciprocating mechanism 200 can drive the connecting component 430 to which the test plug 600 belongs to engage with the test mechanism 500 again, and drive the test mechanism 500 and the test plug 600 to continue to complete the fatigue test of the router joint; at the same time, when the replaced test plug 600 is combined with the router joint and no electrical signal is generated, at this time the test host drives the control mechanism 700 to work again, so that the control mechanism 700 limits and fixes the retracted test mechanism 500 again. This can facilitate the staff to quickly judge that the joint of the router fails, and combined with the reciprocating times of the test mechanism 500, quickly obtain the plugging and unplugging times of the joint on the router, so as to efficiently complete the fatigue test work of the joint, improve the accuracy of the fatigue test data of the router joint, and improve the flexibility and adaptability of the test tooling;

[0074] The above is the working principle of the fatigue test tooling for the router joint.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
