[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] See also Figure 1 , 2 As shown in , 3, an embodiment of the utility model provides a multifunctional experimental table for controller testing, including a table body 1, a test board integrated box 2 is vertically embedded on one side of the table body 1 and along the length extension direction of the table top, a plurality of FCU test grids 3 are embedded on the table top next to one side of the test board integrated box 2, a connecting hole is opened on the inner wall of the FCU test grid 3, a test harness is passed through the connecting hole, one end of the test harness is pluggable to the controller, and the other end is pluggable to the test board integrated box 2; a hydraulic lifting device is fixedly arranged on the bottom of the test board integrated box 2, and the test board integrated box 2 is lifted and lowered in the table body 1 by the hydraulic lifting device.

[0029] In this embodiment, if Figure 1As shown, the table body 1 is a rectangular structure with one side facing inward, with an arc-shaped side wall in front and a straight side wall in the back. A vertical groove is provided on one side of the table body 1 and extends inward along the length of the table top, and the test board integrated box 2 is embedded therein and moves up and down in the vertical groove. The shape and size of the vertical groove are compatible with the test board integrated box 2, and the test board integrated box 2 can be embedded in the vertical groove as a whole, so that the test board integrated box 2 can be received in the experimental table body 1, thereby optimizing the overall space of the experimental table and improving the space utilization rate of the experimental table.

[0030] The test board integrated box 2 is provided with a controller test board and a switching power supply connected thereto. The test board integrated box 2 is an integrated box for placing the fuel cell controller test board and the switching power supply for powering the test board. Among them, the fuel cell controller test board adopts existing electrical components, mainly including test circuits, interfaces and connectors. The test circuit is the core part of the test board. It adopts the existing test circuit, which includes test circuits and components related to the performance of the fuel cell controller, and is used to test various performance indicators of the fuel cell controller; there are usually a variety of interfaces and connectors on the test board, which are used to connect the fuel cell controller, test equipment and power supply, etc., to ensure the signal and data transmission during the test, and to monitor and record the performance data of the fuel cell controller in real time.

[0031] The test board integrated box 2 has a solid shell that can protect the test board, circuits, switching power supply and other components inside it from external influences. The integrated box contains circuits connecting the test board and the switching power supply. The operator needs to design and install it according to specific layouts and specifications. The technicians in this field can design it according to the actual situation to ensure the stability of the signal and data transmission during the test.

[0032] In some embodiments, the test panel integrated box 2 may be configured as a box having a size of 750 mm×485 mm.

[0033] The test board integrated box 2 is provided with double doors on the rear side, which makes it easy for operators to check, replace and repair equipment, thereby improving work efficiency. At the same time, the integrated box has a large space inside, which can accommodate more test boards and switching power supplies and other equipment, and can support the testing of multiple fuel cell controllers at the same time, thereby improving the testing efficiency.

[0034] Through the above technical solution, the test board integrated box 2 integrates the fuel cell controller test board, circuits, switching power supply and other components in one box, which can be easily centrally managed and maintained, thereby improving the efficiency and convenience of the test work.

[0035] In this embodiment, a receiving groove is provided inwardly on the tabletop next to one side of the vertical groove, and a plurality of FCU test cells 3 are provided in the receiving groove. A connecting hole is provided on the inner wall of the FCU test cell 3 close to the test board integrated box 2, and the connecting hole is connected with the vertical groove, and a test harness is passed through the connecting hole. A controller is placed in the FCU test cell 3, and the controller test board in the test board integrated box 2 is connected to the controller through the test harness, making the test process more convenient, and the test can be performed without moving the test board, thereby reducing the error rate in the test process.

[0036] In some embodiments, 20 FCU test grids 3 can be provided, and the size can be set to 200mm×30mm, which can meet the simultaneous testing of 20 controllers. In this embodiment, the test process of multiple fuel cell controllers is concentrated in one area for easy management and monitoring. At the same time, each FCU test grid 3 is an independent test environment, and separate tests can be performed on different controllers.

[0037] In this embodiment, if Figure 4 As shown, the hydraulic lifting device includes a hydraulic cylinder 8, in which a piston rod 9 is provided, one end of the piston rod 9 is fixed to the piston inside the hydraulic cylinder 8, and the other end passes through the cylinder head of the hydraulic cylinder 8, extends to the outside of the hydraulic cylinder 8 and is fixedly connected to the bottom of the test board integrated box 2. The hydraulic lifting device also includes a hydraulic operating handle 5, which is connected to the switch 7 of the hydraulic pump through a connecting rod 6. When the hydraulic operating handle 5 is pressed or pulled up, the switch 7 of the hydraulic pump will be driven by the connecting rod 6 to perform corresponding actions; the hydraulic pump is connected to the hydraulic cylinder 8 through a hydraulic pipeline to transport and recover hydraulic oil.

[0038] The hydraulic cylinder 8 and related structures in the hydraulic lifting device are arranged inside the table body 1, and the hydraulic operating handle 5 passes through the arc-shaped side wall of the table body 1 and is placed outside the table body 1 to facilitate corresponding operations on the hydraulic operating handle 5.

[0039] Triangular brackets 10 are provided between the two sides of the bottom of the test board integrated box 2 and the two side walls of the vertical groove (only one side of the triangular bracket is schematically drawn in the attached figure). One end of the triangular bracket 10 is fixedly connected to one side of the bottom of the test board integrated box 2, and the other end is fixedly provided on one side wall of the vertical groove. Triangular brackets 10 are fixedly provided on both sides of the bottom of the integrated box. The triangular brackets 10 are bendable structures. When the test board integrated box 2 is inside the table body 1, they are bent. When the bottom of the test board integrated box 2 rises to the height of the table, they are straightened and play a supporting role on both sides of the integrated box. In addition, the supporting role of the piston rod 9 at the bottom of the integrated box can effectively support and stabilize the test board integrated box 2 to prevent it from tilting or shaking, thereby providing a reliable platform for the test operation. The lifting device designed in this way not only lifts smoothly, but also can withstand large loads.

[0040] The working principle of lifting and lowering the test board integrated box 2 is as follows: press the hydraulic operating handle, drive the hydraulic pump through the connecting rod 6 to start working, press the hydraulic oil into the hydraulic cylinder 8, and the pressure in the hydraulic cylinder 8 gradually increases, pushing the piston rod 9 to move upward, thereby raising the integrated box. During the raising process of the integrated box, the triangular brackets 10 on both sides also extend with it, until the integrated box is raised to the level of the desktop, the triangular brackets 10 straighten to play the role of fixed support, and cooperate with the support of the piston rod 9 to achieve the stability of the integrated box.

[0041] When the hydraulic operating handle is pulled up, the hydraulic pump stops working, the hydraulic oil flows out of the hydraulic cylinder 8, the pressure in the hydraulic cylinder 8 gradually decreases, the piston rod 9 descends, the test plate integrated box 2 also descends, and compresses the triangular brackets 10 on both sides to bend them, until the integrated box is completely retracted into the vertical groove.

[0042] In this embodiment, if Figure 3 As shown, a multifunctional tool compartment 4 is provided on the desktop beside one side of the FCU test compartment 3. The multifunctional tool compartment 4 is a groove structure, and various types of compartments are separated by partitions inside the compartment. The length and width of the compartments are different, so that tools or parts of different sizes can be stored in an orderly manner, avoiding the situation where tools on the desktop are placed randomly and causing a mess. The operator can quickly find the required tool, thereby saving time and improving work efficiency. At the same time, it can also avoid collision and friction between tools and reduce wear and damage of tools.

[0043] In some embodiments, the partitions may be made of acrylic plates, which can be disassembled repeatedly, so that the spatial layout of the tool grid can be flexibly adjusted according to actual needs, greatly improving the adaptability of the space, while also facilitating maintenance and cleaning.

[0044] Working principle details:

[0045] When testing the fuel cell controller, the test board integrated box 2 embedded in the table body 1 is raised to the table top height by pressing the hydraulic operating handle 5, and the single controller or multiple controllers to be tested are placed in the independent FCU test grid 3 respectively, and the controller is connected to the test board in the test board integrated box 2 through the test harness in the corresponding test grid to perform single or multiple controller tests. At the same time, various tools can be placed in the multifunctional tool grid 4 embedded on the desktop in an orderly manner to keep the laboratory table clean and tidy and avoid the tools being placed randomly. After the test is completed, pull up the hydraulic operating handle 5 to lower the test board integrated box 2 back until it is completely embedded in the table body 1. At this time, the laboratory table can be used as a table, which improves the space utilization rate.

[0046] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
