[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] This embodiment provides a mother-daughter vehicle, such as Figures 1-3 As shown, the mother and daughter carts are used to transport samples 100 into the test chamber. Specifically, it includes a mother cart 10 and a daughter cart assembly 20. The mother cart 10 includes a body 11, and the bottom of the body 11 is provided with multiple first pulleys 12. The height of the body 11 is the same as the bottom height of the test chamber door. The daughter cart assembly 20 includes a first daughter cart 21. The top of the first daughter cart 21 forms a receiving space 211, which can accommodate multiple samples 100. The first daughter cart 21 is slidably connected to the mother cart 10, and the first daughter cart 21 can be selectively locked onto the mother cart 10 or slid off the mother cart 10.

[0037] After loading the sample 100 to be tested onto the first trolley 21, the mother trolley 10 can be directly pushed to the door of the test chamber. Since the bottom of the door is the same height as the mother trolley 10, and the first trolley 21 is slidably connected to the mother trolley 10, the first trolley 21 carrying the sample 100 can be directly dragged, allowing it to quickly slide off the mother trolley 10 and into the test chamber. Because the first trolley 21 can be locked onto the mother trolley 10, it will not slide or slide relative to the mother trolley 10 when the mother trolley 10 is pushed towards the test chamber, thus improving stability during transportation. Therefore, the mother and daughter trolleys in this embodiment can increase the loading and unloading speed of the sample 100, thereby improving transportation efficiency and ensuring the convenience of loading and unloading the sample 100.

[0038] It should be noted that, as Figures 1-3As shown, the mother carriage 10 also includes a push-pull frame 14, which is located on one side of the body 11 along its length. Operators can apply pushing or pulling force to the push-pull frame 14 to move the mother and daughter carriages to the test chamber door, saving time and effort and effectively improving operational convenience. Furthermore, a handle 215 is provided at one end of the first daughter carriage 21 along its length, allowing for pushing and pulling of the first daughter carriage 21, further enhancing ease of use.

[0039] Specifically, such as Figures 1-3 As shown, the bottom of the first sub-carriage 21 is equipped with a pulley system, which includes multiple second pulleys 212. The mother carriage 10 is provided with a sliding groove 13, within which the second pulleys 212 can slide. The width of the second pulleys 212 is the same as the width of the sliding groove 13. This arrangement not only has a simple structure but also provides good sliding performance. Furthermore, because the widths of the second pulleys 212 and the sliding groove 13 are the same, the sliding groove 13 also provides good guidance, ensuring that the first sub-carriage 21 does not deviate from the preset direction during sliding, thereby improving the smoothness of the sliding.

[0040] In addition, such as Figures 1-3 As shown, multiple pulley sets are provided, and multiple second pulleys 212 within the same pulley set are arranged along the length of the vehicle body 11. The sliding grooves 13 are correspondingly arranged with the pulley sets. This structure can ensure the sliding effect, and can still ensure the smoothness and stability of sliding even when facing a heavy sample 100. Moreover, each pulley set has a corresponding sliding groove 13, which can further ensure that the first sub-carriage 21 will not deviate from the preset direction during the sliding process.

[0041] It should be noted that all the second pulleys 212 have a self-locking function. When pushing the mother car 10 close to the test box, the multiple second pulleys 212 can be switched to the locked state. That is, during transportation, it can be ensured that the second pulleys 212 will not roll in the slide 13, thereby preventing the first daughter car 21 from falling off the mother car 10 during transportation.

[0042] Furthermore, to avoid the inconvenience of transferring the sample 100 to the first carriage 21 when it is placed on the mother carriage 10, the first carriage 21 can be removed from the mother carriage 10 first, and the second pulley 212 can be switched to the locked state to ensure its stability on the ground. Then, the sample 100 can be transferred to the first carriage 21. Multiple lifting lugs 23 are installed circumferentially on the top of the first carriage 21. The first carriage 21 is then lifted onto the mother carriage 10 using lifting tools. Finally, the lifting lugs 23 are removed from the first carriage 21 to facilitate the subsequent stacking of other workpieces on the first carriage 21. This operation not only saves a lot of labor costs but also ensures ease of operation.

[0043] To further improve the stability of the connection between the first subcar 21 and the mother car 10, such as Figure 1 , Figure 2 and Figure 4 As shown, the mother car 10 and the first daughter car 21 are connected and fixed to each other by a plug-in assembly 30. That is, after the first daughter car 21 is hoisted onto the mother car 10, the mother car 10 and the first daughter car 21 are fixed together by the plug-in assembly 30, thereby ensuring the stability of the first daughter car 21 on the mother car 10 and preventing the first daughter car 21 from falling off the mother car 10 during transportation.

[0044] In this example, such as Figure 4 As shown, a limiting member 33 is provided on the first sub-cart 21. The limiting member 33 has a limiting hole. The insertion rod 31 is generally inverted "L" shape, and one end of the insertion rod 31 can pass through the limiting hole and can move in the vertical direction. The mother car 10 is provided with an insertion port 32. After the first sub-cart 21 is hoisted onto the mother car 10, the multiple second pulleys 212 are switched to the locked state, and then the insertion rod 31 is inserted into the insertion port 32. Under the action of gravity and the limiting member 33, the first sub-cart 21 and the mother car 10 can be connected into a whole, thereby further ensuring that the first sub-cart 21 will not shake and improving the stability of transporting the sample 100.

[0045] In addition, such as Figure 1 As shown, the subcarriage group 20 also includes a second subcarriage 22, which can be stacked on the first subcarriage 21 along the thickness direction. The second subcarriage 22 can carry the sample 100. By setting the second subcarriage 22, the number of samples 100 that the mother car 10 can transport at one time can be further increased. Moreover, since the second subcarriage 22 is stacked on the first subcarriage 21, the length of the mother car 10 will not be increased, which not only improves the transportation efficiency but also improves the space utilization of the mother car 10.

[0046] In addition, such as Figure 2 and Figure 5 As shown, the first subcarriage 21 is provided with multiple guide plates 214 along its circumference. The multiple guide plates 214 and the top of the first subcarriage 21 together form a guide groove, within which the second subcarriage 22 can be placed. Figure 5 As shown, multiple guide plates 214 are bent away from the first subcarriage 21, so they can play a good guiding role when stacking the second subcarriage 22, improve transportation efficiency, reduce stacking difficulty, and the guide groove can also improve the stability of the second subcarriage 22 on the first subcarriage 21.

[0047] To further improve the stability of the second subcar 22 on the first subcar 21, such as Figure 1 , Figure 2 and Figure 6As shown, the second subcart 22 has a hook 221 along its outer periphery, and the first subcart 21 has a buckle 213 along its circumference. When the second subcart 22 is stacked on the first subcart 21, the buckle 213 can be engaged with the hook 221 to form a subcart group 20. The engagement of the buckle 213 with the hook 221 not only facilitates operation but also further enhances the stability of the subcart group 20.

[0048] It should be noted that in this embodiment, the buckle 213 is an adjustable structure. The first subcarriage 21 is provided with an adjustment hole. One end of the buckle 213 is threaded into the adjustment hole. Before use, the extension length of the buckle 213 can be adjusted by rotating it, thereby adjusting or locking the subcarriage group 20 according to actual needs.

[0049] To further improve the convenience of handling, such as Figure 1 As shown, both the top of the first trolley 21 and the second trolley 22 are equipped with multiple lifting lugs 23 along the circumference. Therefore, the sample 100 can be transported to the second trolley 22 on the ground first, and then the second trolley 22 can be hoisted onto the first trolley 21 by connecting it to the lifting lugs 23 using a hoisting tool. This is not only convenient for express delivery but also saves time and effort. When it is necessary to unload the trolley assembly 20, the first trolley 21 can be pushed directly, and the second trolley 22 can be transported down together with the hooks 213 and 221. The function of the lifting lugs 23 on the first trolley 21 has been described above and will not be repeated here.

[0050] Furthermore, in this embodiment, the multiple lifting lugs 23 are detachably connected to both the first sub-cart 21 and the second sub-cart 22. After the first sub-cart 21 is hoisted onto the mother car 10, the lifting lugs 23 are removed to avoid interfering with the stacking of the second sub-carts 23. After the second sub-cart 22 is installed, the multiple lifting lugs 23 can be removed for subsequent use and to facilitate the stacking of multiple second sub-carts 22 along the thickness direction, further improving transportation efficiency. It should be noted that in this embodiment, to accommodate the height of the test chamber, only one second sub-cart 22 is shown stacked. In other embodiments, the number of second sub-carts 22 can be adjusted according to actual needs. If multiple second sub-carts 22 are required, any two interconnectable structures need to be added to the second sub-carts 22 to ensure stability during use.

[0051] In addition, such as Figure 7As shown, both the first sub-cart 21 and the second sub-cart 22 are equipped with a grid plate 24. The grid plate 24 has a hollow structure (i.e., multiple convection holes 241 are provided throughout along the thickness direction). The grid plate 24 is used to support the sample 100. Firstly, the hollow structure facilitates air convection above and below the grid plate 24, thereby ensuring the temperature uniformity within the test chamber. Secondly, the grid plate 24 is made of FR4 epoxy fiberglass board, which still has high mechanical strength and good insulation properties at 150℃, making it suitable for testing electronic products. Furthermore, the grid plates 24 are welded to the frame of the first sub-cart 21 and the second sub-cart 22, thereby increasing the load-bearing capacity of the grid plate 24 and improving its service life. The above design allows the sub-cart group 20 to be placed inside the environmental test chamber as a test rack for carrying the sample 100, thus avoiding the need to move the sample 100 back to the test rack, improving the efficiency and workload of the environmental test chamber experiment.

[0052] Referring to the accompanying drawings, the usage process of the mother-daughter vehicle in this embodiment is explained as follows:

[0053] First, place the required sample 100 on the first subcarriage 21, then install the lifting lug 23 on the first subcarriage 21, and use the lifting tool to lift the first subcarriage 21 along with the sample 100 onto the mother car 10. Then insert the insertion rod 31 into the insertion port 32, switch the multiple second pulleys 212 to the locked state, and remove the lifting lug 23.

[0054] Next, place sample 100 on the second subcart 22, and use a hoisting tool to hoist the second subcart 22 onto the first subcart 21. Secure it with buckles 213 and hooks 221, and remove the lifting lugs 23. Determine whether more second subcarts 22 need to be stacked according to actual needs. If so, repeat the above operation.

[0055] Finally, push the mother and daughter carts to the door of the test chamber, release the locking state of the second pulley 212, pull out the plug rod 31, push the daughter cart group 20 into the test chamber, and switch the second pulley 212 to the locking state to ensure its stability during the experiment, and wait for the experiment to be completed; after the experiment, push the daughter cart group 20 back to the mother cart 10.

[0056] In summary, the mother-daughter vehicle provided in this embodiment not only improves loading and unloading speed but also enhances transportation efficiency and ensures ease of loading and unloading. Furthermore, the daughter vehicle group 20 can be placed inside the environmental test chamber as a test rack carrying the sample 100, thereby avoiding the need to move the sample 100 back to the test rack and improving operational efficiency and workload during environmental test chamber experiments.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
