Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment, and in particular to a testing device. Background Technology

[0002] For products requiring thermal insulation during testing (such as power supplies or inverters), current testing equipment typically incorporates a partition within the chassis, dividing the rack into front and rear sections. The front section houses the product to be tested, while the rear section contains the main unit module. An interface module, consisting of multiple connectors, is usually located in the front section and connects to the main unit module in the rear section. Specifically, during testing, the product under test is placed in the front section and then connected to the interface module via cables or conduits. This establishes a connection between the product and the main unit module. The connection can be at least one of electrical, pneumatic, or hydraulic. For example, when the product under test is a power supply or inverter, both an electrical and hydraulic connection (allowing the main unit module to supply coolant to the product) are required. More specifically, the wiring terminals of the main unit module inside the current testing equipment chassis face backwards. This means that the main unit module's wiring terminals need to be rotated 180° before connecting to the interface module located at the front. This can lead to the problem of easy breakage of cables or pipes between the main unit module and the interface module. In addition, because the main unit module's wiring terminals face backwards, it is currently necessary to open the back panel of the chassis to inspect or maintain the main unit module. This means that the current testing equipment cannot be placed against a wall during use. In other words, the current testing equipment must have sufficient operating space at the back for operators to enter and for the back panel to open sufficiently. This results in the testing equipment requiring a large footprint.

[0003] Therefore, improvements to existing technologies are necessary.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0005] This utility model provides a testing device that mainly solves the technical problem of large floor space occupation caused by the need to open the back panel to inspect or maintain the main unit module behind the device in existing testing devices with internal partitions.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A testing device includes a testing host and a cargo trolley. The testing host includes a chassis and a partition disposed within the chassis. The partition is detachably connected to the chassis and divides the internal space of the chassis into a front area and a rear area. At least one testing station is disposed in the front area. The testing host also includes a host module disposed in the rear area and an interface module disposed on one side of the testing station. The host module has a wiring terminal facing the front area, and the interface module includes multiple connectors connected to the wiring terminal of the host module. The cargo trolley is pushed into the testing station or moved out of the testing station.

[0008] In one of the technical solutions, the interface module is disposed on the front face of the chassis, and the chassis has a receiving area behind the interface module. The receiving area extends into the rear area and is used to receive cables or pipes connected between the connector and the host module.

[0009] In one of the technical solutions, two test stations are provided in the front area. The cargo trolley is pushed into the test station or moved out of the test station. An interface module is provided on the side of the two test stations that are far apart from each other. A receiving area is provided behind each interface module.

[0010] In one of the technical solutions, a frame is fixed inside the chassis between the front region and the rear region, and multiple removable partitions are fixed on the frame.

[0011] In one of the technical solutions, a fan assembly is provided in the test station and near the partition. The fan assembly is used to blow air forward, and one side of the fan assembly is rotatably connected to the chassis in the front-back direction.

[0012] In one of the technical solutions, the fan assembly includes a door frame and a plurality of fans fixed on the door frame. One side of the door frame is rotatably connected to the chassis in the front-rear direction, and the other side of the door frame is provided with a locking member for fixing to the chassis.

[0013] In one of the technical solutions, the top of the chassis is provided with a first air inlet and a first air outlet, both of which are located above the front area and are connected to the front area.

[0014] In one of the technical solutions, a second air outlet is provided on the top of the chassis, and a second air inlet is provided on the back of the chassis. The second air outlet is located above the rear area and communicates with the rear area.

[0015] In one of the technical solutions, the cargo trolley includes a frame and multiple shelves disposed on the frame. One end of each shelf is rotatably connected to the frame and can be flipped up relative to the frame. A buffer spring is connected between the shelf and the frame.

[0016] Compared with the prior art, the testing equipment provided by this utility model has at least the following beneficial effects:

[0017] Before testing, the product to be tested needs to be placed on a trolley, which is then pushed into the corresponding test station in the front area. Next, the product on the trolley is connected to the interface module via cables or conduits, establishing a connection between the product and the host module in the rear area. Testing can then proceed. After testing, the cables or conduits between the tested product and the interface module are disconnected, and the trolley is moved outwards to a designated location. When maintenance or repair of the host module in the rear area is required, the trolley in the test station can be moved outwards first. Then, personnel can enter the front area and remove the partition, exposing the host module's wiring terminals, allowing for maintenance or repair. In other words, this solution employs a movable trolley for material supply, designs the main module's wiring terminals to face forward, and makes the partitions removable. This allows operators to provide the products to be tested to the front area while simultaneously accessing the front area to inspect or maintain the main module. Operators do not need to open the back panel of the chassis to perform maintenance or repairs on the main module. Therefore, the testing equipment in this solution can be placed as close to the wall as possible, minimizing the maintenance space required behind the testing equipment and reducing its footprint on the ground. Furthermore, because the main module's wiring terminals are designed to face forward, the cables or conduits connecting the main module and the interface module do not need to be bent 180°, significantly reducing the risk of cable or conduit breakage and thus improving the reliability and stability of the testing equipment for product testing.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Please refer to the following: Figures 1 to 6This utility model embodiment provides a testing device, mainly including a testing host 1 and a cargo cart 2. The testing host 1 specifically includes a chassis 11, a host module 12, and an interface module 13. A partition 14 is provided inside the chassis 11. The partition 14 is detachably connected to the chassis 11 and divides the internal space of the chassis 11 into a front area 15 located in the front region and a rear area 16 located in the rear region. At least one testing station 17 is provided in the front area 15. The number of testing stations 17 is the same as the number of cargo carts 2. In this embodiment, two testing stations are preferably provided in the front area 15. Test station 17 is equipped with two cargo carts 2. During testing, each cargo cart 2 needs to be pushed into a corresponding test station 17. The interface module 13 is provided on one side of the test station 17. The host module 12 is housed in the rear area 16, and the wiring terminal 121 of the host module 12 faces the front area 15. That is, the wiring terminal 121 of the host module 12 faces forward. The interface module 13 includes multiple connectors 131, which need to be connected to the host module 12 located in the rear area 16 through cables or pipes.

[0037] Specifically, before testing, the product to be tested needs to be placed on the trolley 2, and then the trolley 2 is pushed into the corresponding test station 17 in the front area 15. Next, the product to be tested on the trolley 2 is connected to the interface module 13 through a cable or pipe, so that the product to be tested is connected to the host module 12 in the rear area 16 through the interface module 13 (at least one of electrical connection, hydraulic connection or pneumatic connection). At this time, the product can be tested. After the test is completed, the cable or pipe between the tested product and the interface module 13 is disconnected, and finally the trolley 2 is moved outward to the designated position.

[0038] When it is necessary to inspect or maintain the main unit module 12 in the rear area 16, the trolley 2 in the test station 17 can be moved outward first, and then the operator can enter the front area 15 and remove the partition 14. At this time, the wiring terminal 121 of the main unit module 12 can be exposed, and the operator can then inspect or maintain the main unit module 12. In other words, this solution uses a movable cargo cart 2 for material supply, and designs the wiring terminal 121 of the main module 12 to face forward, and the partition 14 to be detachable. This allows operators to provide the product to be tested to the front area 15, and also allows them to enter the front area 15 to inspect or maintain the main module 12. Operators do not need to open the back panel of the chassis 11 to inspect or maintain the main module 12. Therefore, the testing equipment in this solution can be placed as close to the wall as possible, that is, the rear of the testing equipment does not need to be reserved too much maintenance space, which helps to reduce the space occupied by the testing equipment on the ground. In addition, since the wiring terminal 121 of the main module 12 is designed to face forward, the cables or pipes connecting the main module 12 and the interface module 13 do not need to be bent 180°, which greatly reduces the risk of cable or pipe breakage between the main module 12 and the interface module 13, thereby improving the reliability and stability of the testing equipment for product testing.

[0039] Please refer to the following: Figures 1 to 3 The interface module 13 is preferably located on the front face of the chassis 11. The chassis 11 has a receiving area 18 behind the interface module 13. This receiving area 18 can accommodate cables or conduits connecting the connector 131 and the host module 12, serving to organize the cables or conduits and facilitate subsequent maintenance. Furthermore, based on the structural design with two test stations 17, it is preferable to have one interface module 13 on each side of the two test stations 17 that are far apart from each other, and a receiving area 18 is provided behind each of the two interface modules 13. During testing, the product at the left test station 17 can be connected to the left interface module 13, and the product at the right test station 17 can be connected to the right interface module 13.

[0040] Please refer to the following: Figure 3 and Figure 6 The chassis 11 has a frame 111 fixed between the front area 15 and the rear area 16. Multiple partitions 14 are fixed on the frame 111. All partitions 14 are detachably connected to the frame 111. When maintenance or upkeep of the rear host module 12 is required, the partition 14 at the designated location can be opened.

[0041] Please refer to the following: Figure 3 , Figure 5 and Figure 7Fan assemblies 19 are installed in each test station 17 near the partition 14. The fan assemblies 19 blow air forward to accelerate heat dissipation for the products being tested. Each fan assembly 19 actually includes a door frame 191 with multiple mounting holes 192, each housing a fan. One side of the door frame 191 is rotatably connected to the chassis 11 in the front-back direction, while the other side has a locking member 193 for securing it to the chassis 11. When maintenance or repair of the rear host module 12 is required, the locking member 193 must be opened first, and the fan assembly 19 must be opened forward before the partition 14 can be disassembled. Given that the fan assembly 19 is located at the rear of the test station 17, this solution preferably also includes a first air inlet 112 and a first air outlet 113 on the top of the chassis 11. Both the first air inlet 112 and the first air outlet 113 are located above and connected to the front area 15, with the first air inlet 112 positioned behind the first air outlet 113. During heat dissipation, cool air enters the front area 15 from the top first air inlet 112, is then driven forward by the fan assembly 19, and finally flows outward from the top first air outlet 113, thus cooling the product being tested within the front area 15.

[0042] Please see Figure 8 The chassis 11 has a second exhaust vent 114 on its top and a second intake vent 115 on its rear. The second exhaust vent 114 is located above and communicates with the rear area 16. During heat dissipation, cool air enters the front area 15 from the top first intake vent 112, is then driven forward by the fan assembly 19, and finally exits from the top first exhaust vent 113. During heat dissipation, cool air flows in from the rear second intake vent 115 and then exits from the top second exhaust vent 114 to cool the host module 12 within the rear area 16.

[0043] Please refer to the following: Figure 9 and Figure 10 The trolley 2 specifically includes a frame 21 and multiple shelves 22 mounted on the frame 21. One end of each shelf 22 is rotatably connected to the frame 21 via a hinge 23, allowing the shelf 22 to be flipped up relative to the frame 21. Furthermore, a buffer spring 24 is connected between the shelf 22 and the frame 21. With this design, operators can flip up the upper shelf 22 and then place the product on the lower shelf 22 or remove the product from the lower shelf 22, reducing the difficulty of loading or unloading products and improving the efficiency of loading or unloading.

[0044] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
