[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1-5 As shown, this embodiment proposes a multi-channel power supply test device for intelligent modules, including a tester 1, a test interface 2, and a test harness 3. The test interface 2 and the test harness 3 are plugged and plugged together. The outer end of the test interface 2 is provided with a linkage slide bar 9, the inner end of the linkage slide bar 9 is provided with a sliding buckle 8, the upper end of the sliding buckle 8 is provided with a positioning frame 10, the upper end of the positioning frame 10 is provided with a telescopic rod 5, the upper end of the telescopic rod 5 is provided with a moving frame 4, the inner end of the moving frame 4 is provided with a side support rod 7, and the outer end of the side support rod 7 is provided with an arc-shaped clamp 6. The arc-shaped clamp 6 is in contact with the test harness 3.

[0028] The number of arc-shaped clamps 6 is set to two sets. The two sets of arc-shaped clamps 6 are movably connected to the center of the movable frame 4, and the outer ends of the arc-shaped clamps 6 are movably connected to the side support rods 7.

[0029] The side support rod 7 is slidably connected to the movable frame 4, and the lower end of the movable frame 4 is fixedly connected to the telescopic rod 5. The telescopic rod 5 is slid up and down along the positioning frame 10.

[0030] The lower end of the positioning frame 10 is fixedly connected to the sliding buckle 8. The sliding buckle 8 slides back and forth along the linkage slide bar 9. The inner end of the linkage slide bar 9 includes a slide groove, a slide rod and a linkage spring.

[0031] It also includes a control module, which is signal-connected to the drive modules of the telescopic rod 5 and the side support rod 7, respectively.

[0032] The control module includes a signal processing unit, a drive command generation unit, and a communication unit. The signal processing unit receives externally input command signals that do not require connection to a specific test harness 3, and analyzes and processes the signals. The drive command generation unit generates electrical signal commands to control the movement of the telescopic rod 5 drive module based on the signals processed by the signal processing unit. The communication unit is responsible for transmitting the electrical signal commands generated by the drive command generation unit to the drive module of the telescopic rod 5 to achieve precise control of the upward movement of the telescopic rod 5.

[0033] When this application is used:

[0034] When the tester 1 does not need to be connected to one of the test harnesses 3, the control module directly controls the telescopic rod 5 in the positioning frame 10 to move upward. Specifically, it sends an electrical signal to the drive module of the telescopic rod 5. The drive module drives the hydraulic / pneumatic transmission mechanism of the telescopic rod 5 to move according to the received electrical signal, so that the telescopic rod 5 slides upward along the positioning frame 10.

[0035] The telescopic rod 5 moves upward, pushing the moving frame 4 upward. Since the upper end of the telescopic rod 5 is fixedly connected to the moving frame 4, the linear upward movement of the telescopic rod 5 drives the moving frame 4 to move upward synchronously.

[0036] During the upward movement of the moving frame 4, the side support rod 7 inside the moving frame 4 moves outward along the inside of the moving frame 4 (this movement is directly controlled by the control module and uses the same moving mechanism as the telescopic rod 5). The inner end of the side support rod 7 slides in the groove of the moving frame 4. Since the outer end of the side support rod 7 is movably connected to the arc-shaped clamp 6, when the two sets of side support rods 7 move upward, they respectively generate an outward pushing force on the two sets of arc-shaped clamps 6, so that the two sets of arc-shaped clamps 6 rotate inward about the central connection point with the moving frame 4, thereby ensuring that the test wire harness 3 can be completely pulled out.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
