[0040] Because electrical products are often manufactured at a high speed, a large number of testing stations are required during testing. These stations are arranged together, and the testing personnel need to constantly move back and forth between the stations to perform the testing and inspection work. This method is highly repetitive for the staff, requires frequent movement, and is extremely labor-intensive. It is very inconvenient for the staff to perform the testing and inspection work, and the testing and inspection efficiency is low, which also makes it easy for testing and inspection errors to occur.

[0041] To address the problems in the prior art, this application provides a load trolley and a testing system with the load trolley. The load trolley can move between multiple testing stations, facilitating the testing and inspection of electrical products by staff, significantly reducing the workload of staff, and significantly improving the testing and inspection efficiency of electrical products, thus reducing the occurrence of testing and inspection errors.

[0042] Example 1

[0043] See Figure 1 The load trolley in this embodiment includes a load trolley body 11, in which a trolley seating area 111, a drive power supply, and a control module are provided. The trolley seating area 111 is used for carrying staff. The drive power supply is connected to the control module and serves as the power source for the load trolley. The control module is communicatively connected to multiple test stations.

[0044] In this embodiment, the load trolley of this application embodiment is used to move between multiple test stations (not shown in the figure). The test stations are used to test the products to be tested. The multiple test stations can be arranged regularly on the production line. For example, the multiple test stations can be arranged in a row on the production line at equal intervals.

[0045] For example, the product to be tested is an electrical appliance to be tested, that is, the test station is used to test the electrical appliance to be tested; it can be understood that in other embodiments, the product to be tested may also be other non-electrical products that need to be tested.

[0046] In this embodiment, the main body 11 of the load trolley is the main frame structure of the load trolley, and the trolley seating 111 provided in the main body 11 of the load trolley is the seating space / position provided in the main body 11 of the load trolley for staff to ride the load trolley. The trolley seating 111 can accommodate at least one staff member.

[0047] The drive power supply (not shown in the figure) is the power source for the load trolley and supplies power to the control module of the load trolley. The control module (not shown in the figure) is communicatively connected to multiple test stations, enabling the load trolley to communicate with multiple test stations. The load trolley can receive signals from multiple test stations and move to the corresponding test station according to the request of the corresponding test station. Understandably, the load trolley can also be driven by staff to move between multiple test stations.

[0048] The load trolley in this embodiment is used to test products, which can be electrical products or other products that need to be tested. In use, staff can ride on the load trolley through the trolley seating area 111 in the main body 11 and move between multiple test stations to perform testing and inspection of electrical products. During testing, the load trolley can also move to the corresponding test station according to the signal sent by the corresponding test station to perform testing and inspection of electrical products. The load trolley facilitates the testing and inspection of electrical products by staff, significantly reduces the labor intensity of staff, and significantly improves the testing and inspection efficiency of electrical products, reducing the occurrence of testing and inspection errors.

[0049] For example, assuming the product to be tested is an air conditioner, when the air conditioner to be tested is located at the corresponding test station, the staff can ride the load cart to move between multiple test stations to carry out the testing and inspection work of the air conditioner. The testing and inspection work of the air conditioner may include wiring and disconnecting the air conditioner from the corresponding test station, as well as watching and observing the testing process. During the test, the load cart can move to the corresponding test station according to the signal sent by the corresponding test station. For example, the corresponding test station can send a corresponding signal to the load cart when the test is completed, thereby causing the load cart to move to the corresponding test station, and the staff can then disconnect the connection.

[0050] See Figure 1 In this embodiment, a seating seat 13 is provided at the trolley seating position 111. The seating seat 13 is used for staff to sit on the load trolley.

[0051] Specifically, the load trolley has a seating seat 13 in the main body 11 of the load trolley. The seating seat 13 is located at the seating position 111 of the trolley and is used by staff to sit. In this embodiment, the seating seat 13 has a seat back.

[0052] In the above structure, when the staff rides the load trolley, they can sit on the seating seat 13 without having to stand on the load trolley, which can further reduce the labor intensity of the staff. In addition, the seating seat 13 not only provides seating space for the staff, but also adopts a higher seat, which can put the staff in a higher position and have better sight, angle and field of vision, making it easier for the staff to check and observe the testing status of the products to be tested on the test platform.

[0053] In this embodiment, the main body 11 of the load trolley can be provided with a handrail 15 near the seat 13. There can be two handrails 15, located on both sides of the seat 13. The handrails 15 can facilitate the staff to get on and off the seat 13, and can also provide a handhold for the staff when sitting on the seat 13, which helps to ensure the safety of the staff when riding the load trolley.

[0054] In this embodiment, the main body 11 of the load trolley is provided with a movable door 14, which is connected to the trolley seating position 111. The movable door 14 is used for staff to enter and leave the load trolley.

[0055] Specifically, the movable door 14 is located on one side of the load trolley body 11 and can open and close onto the load trolley body 11; the movable door 14 facilitates the entry and exit of staff members from the load trolley and provides convenience for staff members to ride the load trolley.

[0056] In this embodiment, a control panel 16 is provided on the main body 11 of the load trolley. The control panel 16 is connected to the control module of the load trolley. When using the load trolley, the staff can control and use the load trolley through the control panel 16, which facilitates the use of the load trolley and improves its practicality and applicability.

[0057] Example 2

[0058] See Figure 1 and Figure 2 Based on the above embodiment one, the difference between this embodiment and embodiment one is that the load trolley in this embodiment is arranged with guide rails 21 between multiple test stations. The load trolley cooperates with the guide rails 21, and the load trolley moves between multiple test stations under the guidance of the guide rails 21.

[0059] For example, the guide rail 21 can be set on the ground and arranged between multiple test stations; for example, the guide rail 21 can be extended along the arrangement direction of the multiple test stations; the load trolley can move between the multiple test stations by sliding its wheels with the guide rail 21 on the ground.

[0060] In the above structure, when the load trolley moves between multiple test stations, the guide rail 21 can guide the movement of the load trolley, facilitating its movement between the multiple test stations. Furthermore, due to the presence of the guide rail 21, which extends along the arrangement direction of the multiple test stations, the distance between the guide rail 21 and the test station can be set when arranging the guide rail 21. Thus, during the movement of the load trolley, there is no need to adjust the distance between the load trolley and the corresponding test station. The guide rail 21 can maintain the distance between the load trolley and the test station, thereby facilitating the use of the load trolley.

[0061] Example 3

[0062] See Figure 1 and Figure 2 Based on the above embodiment two, the difference between this embodiment and embodiment two is that the load trolley in this embodiment has a guide rail 21 that is arranged between multiple test stations; a guide slide assembly 12 is provided on the outer side of the load trolley body 11, and the guide slide assembly 12 is used to slide with the vertical slide rail.

[0063] Specifically, the vertical slide rail is the guide rail 21 that is not installed on the ground, but maintains a certain height relative to the ground, see [reference]. Figure 2 , Figure 2The diagram shows a schematic structure of a vertical slide rail. In this embodiment, the guide rail 21 is provided with a mounting bracket 22. When setting the guide rail 21, the guide rail 21 can be installed by the mounting bracket 22 so that the guide rail 21 is kept at a certain height relative to the ground. For example, a heavy frame can be placed on the ground and the guide rail 21 can be installed on the frame by the mounting bracket 22.

[0064] In this embodiment, the guide slide assembly 12 can be specifically disposed on one outer side of the load trolley body 11. For example, one outer side of the load trolley body 11 is the front side of the load trolley body 11, which is opposite to the test platform.

[0065] In the above structure, the guide rail 21 is a vertical slide rail arranged between multiple test stations, which eliminates the need to place the guide rail 21 on the ground, thus protecting the ground. Furthermore, by setting the guide slide assembly 12 on the load trolley body 11 to cooperate with the vertical slide rail, the arrangement of the guide rail 21 can be facilitated, and it can play a good guiding role in the movement of the load trolley.

[0066] Example 4

[0067] See Figures 1 to 5 Based on the above embodiment three, the difference between this embodiment and embodiment three is that the load trolley in this embodiment includes a limiting bracket 121 and a guide slider 122. The limiting bracket 121 is disposed on the outer side of the load trolley body 11, and the guide slider 122 is disposed on the limiting bracket 121 for sliding cooperation with the vertical slide rail.

[0068] In this embodiment, the limiting bracket 121 includes a vertical bracket and a horizontal bracket. The horizontal bracket is connected to the bottom of the vertical bracket and to the outside of the load trolley body 11. The guide slider 122 can be disposed on the horizontal bracket or the vertical bracket of the limiting bracket 121.

[0069] In the above structure, the guide slide assembly 12 adopts a limiting bracket 121 and a guide slide block 122. The limiting bracket 121 can play a certain limiting role when the load trolley moves, and has a good guiding effect on the movement of the load trolley. The guide slide block 122 can easily slide with the vertical slide rail and has good sliding stability.

[0070] Furthermore, in this embodiment, there are two guide sliders 122. One guide slider 122 is disposed on the limiting bracket 121, and the other guide slider 122 is disposed on the outer side of the load trolley body 11. A guide groove is formed between the two guide sliders 122, and each of the two guide sliders 122 is provided with a guide pulley 1221.

[0071] Specifically, one guide slider 122 is disposed on the vertical support of the limiting bracket 121, and another guide slider 122 is disposed on the outer side of the load trolley body 11; multiple guide pulleys 1221 are provided, and for example, the guide pulleys 1221 can be universal bullseyes.

[0072] In this embodiment, both guide sliders 122 are provided with mounting holes 1222. The two guide sliders 122 can be installed on the vertical support of the limiting bracket 121 and the outer side of the load trolley body 11 through the mounting holes 1222 and fasteners (e.g., bolts).

[0073] In the above structure, there are two guide sliders 122, and a guide groove is formed between the two guide sliders 122, which can make the vertical slide rail clamp between the two guide sliders 122, so as to better ensure the stability of the load trolley sliding; the guide pulley 1221 can play a role in assisting the sliding and improving the smoothness of the sliding effect.

[0074] It should be noted that, in Figures 2 to 4 In the middle, the guide rail 21 (i.e., the vertical slide rail) is not yet clamped between the two guide sliders 122. In actual use, the guide rail 21 will be clamped between the two guide sliders 122.

[0075] Understandably, in other embodiments, the guide slider 122 may also be a single slider, which may have a guide groove, and the guide slider 122 slides in cooperation with the vertical slide rail through the guide groove.

[0076] In this embodiment, two guide slide components 12 are provided. The two guide slide components 12 are located on the same outer side of the load trolley body 11. Using two guide slide components 12 can greatly improve the movement stability of the load trolley and make the load trolley safer.

[0078] See Figures 1 to 5 This application provides a test system for a load trolley having any of the embodiments one to four described above. The test system also includes multiple test stations, which are used to test the product to be tested; the load trolley is used to move between the multiple test stations.

[0079] The testing system with the load trolley in this application embodiment allows staff to ride the load trolley and move between multiple testing stations during testing. This facilitates the testing and inspection of electrical products, significantly reduces the workload of staff, and significantly improves the efficiency of testing and inspection of electrical products, reducing the occurrence of testing and inspection errors.

[0080] Example 6

[0081] See Figures 1 to 5 Based on the above embodiment five, the difference between this embodiment and embodiment five is that the test system with the load trolley in this embodiment also includes a guide rail 21, which is arranged between multiple test stations, and the load trolley cooperates with the guide rail 21.

[0082] For example, the guide rail 21 can be set on the ground and arranged between multiple test stations; for example, the guide rail 21 can be extended along the arrangement direction of the multiple test stations; the load trolley can move between the multiple test stations by sliding its wheels with the guide rail 21 on the ground.

[0083] In this embodiment, the guide rail 21 is actually a vertical slide rail arranged between multiple test stations; a guide slide assembly 12 is provided on the outer side of the load trolley body 11, and the guide slide assembly 12 is used to slide with the vertical slide rail.

[0084] In the above structure, the guide rail 21 can guide the movement of the load trolley, making it easy for the load trolley to move between multiple test stations, and there is no need to adjust the distance between the load trolley and the corresponding test station during the movement.

[0085] In all the above embodiments, "large" and "small" are relative terms, "more" and "less" are relative terms, and "upper" and "lower" are relative terms. The embodiments of this application will not elaborate further on the expression of such relative terms.
