[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Reference Figures 1 to 5This utility model discloses a testing fixture for the circuit frame of a new energy vehicle made of plastic material. It includes a main body 1, a protective frame 13 fixedly connected to the inner surface of the main body 1, a guide member 7 fixedly connected to the surface of the protective frame 13, a limiting mechanism 12 provided on the upper surface of the guide member 7, a movable plate 3 slidably connected to the inner surface of the protective frame 13, a connecting cylinder 18 fixedly connected to the lower surface of the movable plate 3, a through groove formed on the surface of the connecting cylinder 18, an L-shaped slide rod 22 slidably connected to the through groove surface of the connecting cylinder 18, and a testing plate 19 fixedly connected to the lower surface of the L-shaped slide rod 22. The detection head 17 is fixedly connected to the lower surface of the detection plate 19, and the support rod 5 is fixedly connected to the lower surface of the main body 1. The limiting mechanism 12 includes a fixed box 1201, a limiting component 1202, a T-shaped slider 1203, a locking block 1204, a spring 1205, and a limiting cylinder 1206. The surface of the locking block 1204 is fixedly connected to the protective frame 13, and the surface of the locking block 1204 away from the protective frame 13 is fixedly connected to the fixed box 1201. A pull plate is slidably connected to the inner surface of the fixed box 1201, and the surface of the pull plate of the fixed box 1201 is fixedly connected to the limiting cylinder 1206. When the detection plate 19 needs to be replaced, the moving end of the electric push rod 6 extends and pushes the connecting frame 2 to move. The connecting frame 2 drives the moving plate 3 to slide along the inner surface of the protective frame 13 through the connecting component 4. When the moving plate 3 moves, it drives the connecting cylinder 18 fixedly connected to it to move synchronously. The movement of the connecting cylinder 18 causes the L-shaped slide rod 22, which is slidably connected within its slot, to move accordingly until the L-shaped slide rod 22 moves to a position where it fits against the inner surface of the limiting member 1202. At this point, the initial positioning and preparation work before replacing the detection plate 19 is completed. Pulling the pull plate inside the fixing box 1201 of the limiting mechanism 12 causes the limiting cylinder 1206 to move, while the spring 1205 is stretched. The limiting cylinder 1206 is removed from the slot surface of the limiting member 1202, thereby releasing the restriction on the limiting member 1202. Then, the limiting member 1202 is moved so that it is removed from the inner surface of the locking block 1204, further releasing the restriction on the L-shaped slide rod 22, allowing the L-shaped slide rod 22 to move smoothly out from the inside of the limiting member 1202. After the restriction is released, the detection plate 19 is moved, causing the L-shaped slide rod 22 to move laterally. The L-shaped slide bar 22 slides on the surface of the through groove of the connecting cylinder 18 until it is completely removed from the groove of the connecting cylinder 18, thereby enabling the smooth replacement of the detection plate 19.
[0025] Electric push rods 6 are fixedly connected to the lower surface of the main body 1 near both sides. A connecting frame 2 is fixedly connected to the moving end of the electric push rod 6. A connecting piece 4 is fixedly connected to the upper surface of the connecting frame 2. The upper surface of the moving plate 3 is fixedly connected to the connecting piece 4 near both sides. The surface of the gear 20 meshes with the surface of the rack 8. A through groove is opened on the surface of the limiting member 1202 near the fixed box 1201. The surface of the through groove of the limiting member 1202 is slidably connected to the limiting cylinder 1206. When the circuit frame is tested, the start motor 11 drives the gear 20 to rotate. When the gear 20 rotates, it drives the rack 8 to move along its length direction, thereby driving the slide plate 14 and the clamping plate 21 to move. The two clamping plates 21 move relative to or in opposite directions on the base plate 15, thereby realizing the clamping or loosening operation of the circuit frame.
[0026] A gear 20 is fixedly connected to the drive end of the motor 11. A base plate 15 is fixedly connected to the inner side of the protective frame 13 near the lower surface. A clamping plate 21 is slidably connected to the upper surface of the base plate 15. A connecting plate 9 is fixedly connected to one side surface of the clamping plate 21. A sliding plate 14 is fixedly connected to the surface of the connecting plate 9 away from the clamping plate 21. A rack 8 is fixedly connected to the lower surface of the sliding plate 14.
[0027] The surface of the spring 1205 near the protective frame 13 is fixedly connected to the locking block 1204. The upper surface of the guide 7 is provided with a sliding groove. The surface of the sliding groove of the guide 7 is slidably connected to the T-shaped slider 1203. The surface of the T-shaped slider 1203 is fixedly connected to the limiting member 1202. A partition 16 is fixedly connected to the lower inner surface of the main body 1. There are two partitions 16. A fixing plate 10 is fixedly connected to the surface between the two partitions 16. A motor 11 is fixedly connected to the upper surface of the fixing plate 10. The end of the limiting cylinder 1206 near the locking block 1204 is designed with an inclined surface, and the lower surface of the limiting member 1202 near the fixing box 1201 is also designed with an inclined surface. Moving the limiting member 1202 down makes the inclined surface of the limiting member 1202 fit with the inclined surface of the limiting cylinder 1206, squeezing the limiting cylinder 1206 and pushing the pull plate inside the fixing box 1201 to move, causing the spring 1205 to extend until the limiting cylinder 1206 reaches above the through groove on the surface of the limiting member 1202. Under the restoring pull of the spring 1205, the limiting cylinder 1206 is inserted into the through groove of the limiting member 1202, thus restricting the limiting member 1202.
[0028] Working principle: When the detection plate 19 needs to be replaced, the electric push rod 6 pushes the connecting frame 2, which in turn drives the connecting piece 4 to move the moving plate 3. The movement of the moving plate 3 causes the connecting cylinder 18 to move, and the L-shaped slide rod 22 follows the connecting cylinder 18 until the L-shaped slide rod 22 moves to the point where its surface is in contact with the inner surface of the limiting piece 1202. At this point, the electric push rod 6 stops pushing the connecting frame 2 and pulls the pull plate inside the fixing box 1201 of the limiting mechanism 12 to move the limiting cylinder 1206. The movement of the pull plate will stretch the spring 1205, removing the limiting cylinder 1206 from the through groove surface of the limiting piece 1202. The restriction on the limiting member 1202 is removed. The moving limiting member 1202 drives the T-shaped slider 1203 to move, so that the limiting member 1202 is removed from the inner surface of the locking block 1204. The moving limiting member 1202 causes the L-shaped slide rod 22 to be removed from the inside of the limiting member 1202, thus removing the restriction on the L-shaped slide rod 22. The moving detection plate 19 drives the L-shaped slide rod 22 to move laterally, so that the L-shaped slide rod 22 slides on the through groove surface of the connecting cylinder 18 until the L-shaped slide rod 22 is removed from the slide groove surface of the connecting cylinder 18. The appropriate detection plate 19 is then replaced, effectively achieving the effect of replacing the detection plate 19 to test circuit tooling of different specifications.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
