Description

Technical Field

[0001] The utility model relates to the technical field of wind tunnel detection, in particular to a vehicle wind tunnel detection device. Background Art

[0002] Automobile radiator wind tunnel testing refers to the aerodynamic performance test of the automobile radiator in a wind tunnel laboratory to evaluate its cooling effect and heat dissipation performance under different environmental conditions. When the automobile radiator is undergoing wind tunnel testing, it needs to be fixed in the wind tunnel.

[0003] For example, the patent with announcement number CN220437713U discloses a wind tunnel test bench for testing automobile radiators, which includes a supporting structure and a clamping structure. The clamping structure is movably connected to the top surface of the supporting structure. The supporting structure includes a base unit and a rotating shaft unit. The base unit is placed on the bottom surface of the clamping structure. The rotating shaft unit is movably connected to the top inner surface of the base unit. The clamping structure includes a load-bearing unit, a stretching unit and a clamping unit. The car radiator is then placed on the inner side of the two clamping plates, and the handle is released, and the clamping plates are rebounded to their original positions by the compression springs, thereby clamping and fixing the car radiator. In this way, the car radiator can be tested for fixation. However, the car radiator is not easy to be operated by one person when fixing the car radiator. A staff member needs to hold the handle all the time to keep the clamping plates away from each other, so that other staff members can place the radiator between the clamping plates for fixation. The operation requires multiple people, which is troublesome. Moreover, the car radiator usually needs to be placed vertically when undergoing wind tunnel testing. The car radiator is only fixed on both sides of the lower end of the car radiator by the clamping plates, and its stability is poor, so it needs to be improved. Utility Model Content

[0007] Furthermore, the limiting assembly includes a limiting rod having one end connected to the surface of the telescopic rod, a groove body is provided on the inner wall of the circular cavity, and the other end of the limiting rod is extended into the groove body, the groove body includes a transverse groove and a rotation groove, and the other end of the limiting rod can move between the transverse groove and the rotation groove.

[0008] Furthermore, blocks are arranged opposite to each other on the base, a rotatable rotating rod is arranged between the blocks, both ends of the rotating rod are extended from the sides of the blocks, and a connecting block connected to the connecting plate is provided at the end of the rotating rod extending from the side of the block.

[0009] Furthermore, a gear is provided at the center of the rotating rod, a moving groove is provided at the center of the base, a slidable moving block is provided in the moving groove, and a rack meshing with the gear is provided on the moving block.

[0014] 1. The utility model, through the arrangement of the limit rod, the transverse groove and the rotation groove, when the pulling block needs to maintain the spacing between the circular plate and the side wall of the limit groove, the pulling block drives the telescopic rod to move, and the movement of the telescopic rod drives the limit rod to move in the transverse groove. When the limit rod continues to move in the transverse groove until the pulling block can no longer be pulled, the rotating pulling block drives the telescopic rod to rotate, and the rotation of the telescopic rod can drive the limit rod to rotate into the rotation groove, so that the rotation groove limits the limit rod. Since the limit rod and the telescopic rod are fixedly connected, the spring cannot push the telescopic rod to move, thereby maintaining the spacing between the circular plate and the side wall of the limit groove, so that the car radiator can be inserted into the limit groove.

[0015] 2. The utility model, through the arrangement of the gear, movable groove, movable block, rack, screw and rotating block, can drive the screw to rotate by rotating the rotating block.

The movement of the movable block can drive the rack to move. The movement of the rack can drive the gear to rotate. The rotation of the gear can drive the rotating rod to rotate, thereby driving the connecting plate to rotate. Moreover, since the screw is threadedly connected to the movable block, the connecting plate can be prevented from continuing to rotate after the rotation angle is determined, thereby adjusting the angle of the automobile radiator, and then testing the experimental data of the automobile radiator in multiple directions.

DETAILED DESCRIPTION

[0021] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0022] The following is combined with Figures 1-4 This embodiment is described in further detail.

Support rods 3 are provided on both sides of the upper end surface of the connecting plate 2. Clamping assemblies are provided on the upper and lower sides of the support rod 3. The clamping assembly includes a fixing block 4 provided on the support rod 3. A limit block 5 is provided on the side of the fixing block 4. A limit groove 6 for inserting the side of the car radiator is provided in the limit block 5. A connecting column 7 is provided on the side of the limit block 5. A circular cavity is provided in the connecting column 7. A telescopic rod 8 that can be extended into the limit groove 6 is provided in the circular cavity. The telescopic rod 8 extends into the limit groove. 6 is provided with a circular plate 9 at the end thereof, a blocking cap 10 is provided at the open end of the circular cavity, a pushing ring 11 is provided on the telescopic rod 8 located in the circular cavity, a spring 12 is provided between the pushing ring 11 and the blocking cap 10 for pushing the telescopic rod 8 to clamp the car radiator, the end of the telescopic rod 8 that does not extend into the limiting groove 6 is extended by the blocking cap 10, and a pulling block 13 for pulling the telescopic rod 8 back is provided at the end of the telescopic rod 8 extending from the blocking cap 10, a limiting component for limiting the telescopic rod 8 after retraction is provided in the circular cavity, and an adjusting component for adjusting the angle of the connecting plate 2 is provided on the base 1.

[0024] In this embodiment, through the arrangement of the base 1, the connecting plate 2, the support rod 3 and the adjustment assembly, the support rod 3 is fixedly connected to the connecting plate 2, and the connecting plate 2 is rotatably connected to the base 1 through the adjustment assembly.

[0025] In this embodiment, by setting the fixing block 4, the limiting block 5 and the limiting groove 6, the fixing block 4 is fixedly connected to the support rod 3, and the limiting block 5 is fixedly connected to the fixing block 4. When fixing the automobile radiator, the automobile radiator can be placed vertically on the connecting plate 2, and the two sides of the automobile radiator are inserted into the corresponding limiting grooves 6, so as to limit the two sides of the automobile radiator, so that the fixation of the automobile radiator on the detection device is more stably.

[0026] In this embodiment, by arranging the connecting column 7, circular cavity, telescopic rod 8, circular plate 9, blocking cap 10, pushing ring 11 and spring 12, the connecting column 7 is fixedly connected to the limit block 5, the pushing ring 11 is fixedly connected to the telescopic rod 8, the circular plate 9 is fixedly connected to the telescopic rod 8, and the blocking cap 10 is threadedly connected to the open end of the circular cavity, so as to install the components in the circular cavity; wherein, the pushing ring 11 is pushed by the spring 12, and the pushing ring 11 drives the telescopic rod 8 to push into the limiting groove 6, thereby driving the circular plate 9 to squeeze the automobile radiator located in the limiting groove 6, so that the circular plate 9 and the side wall of the limiting groove 6 squeeze the automobile radiator at the same time, thereby fixing the automobile radiator, so that the clamping component has a better effect of fixing the automobile radiator.

[0027] In this embodiment, the pull block 13 and the limit assembly are set so that the pull block 13 is fixedly connected to the telescopic rod 8. The pull block 13 can be pulled first to make the circular plate 9 close to the connecting column 7, so that the distance between it and the side wall of the limit groove 6 is increased, so that the side of the car radiator can be inserted into the corresponding limit groove 6.

[0028] Among them, the telescopic rod 8 is limited by the limiting component. When the staff is fixing the car radiator, they can first pull the pull block 13, and through the cooperation of the limiting component, a certain distance can be maintained between the circular plate 9 and the side wall of the limiting groove 6 to facilitate the insertion of the car radiator. There is no need for the staff to keep pulling the pull block 13 and cooperate with other staff to fix the car radiator. Only one staff member is needed to insert the side of the car radiator into the corresponding limiting groove 6, and the car radiator can be disassembled and assembled on the detection device, saving human resources.

[0029] In actual use, in order to enable the detection device to stably fix the automobile radiator, support legs 14 for supporting the base 1 are respectively provided at the four corners of the base 1.

[0030] See also Figures 1-4 In this embodiment, the limiting assembly includes a limiting rod 100 whose one end is connected to the surface of the telescopic rod 8, and a groove body is provided on the inner wall of the circular cavity. The other end of the limiting rod 100 is extended into the groove body, and the groove body includes a transverse groove 101 and a rotating groove 102. The other end of the limiting rod 100 can move between the transverse groove 101 and the rotating groove 102.

[0031] In this embodiment, the transverse groove 101 is arranged along the axial direction of the connecting column 7, and the rotating groove 102 is arranged along the circumferential direction of the connecting column 7, and the two are connected to form a groove body; wherein, by setting the limiting rod 100, the transverse groove 101 and the rotating groove 102, the limiting rod 100 is fixedly connected to the telescopic rod 8. When the pulling block 13 is pulled to maintain the spacing between the circular plate 9 and the side wall of the limiting groove 6, the pulling block 13 drives the telescopic rod 8 to move, and the movement of the telescopic rod 8 drives the end of the limiting rod 100 to move in the transverse groove 101. When the end of the limit rod 100 continues to move in the horizontal groove 101 until the pull block 13 can no longer be pulled, the rotating pull block 13 drives the telescopic rod 8 to rotate. The rotation of the telescopic rod 8 can drive the end of the limit rod 100 to rotate into the rotating groove 102, so that the rotating groove 102 limits the limit rod 100. Since the limit rod 100 and the telescopic rod 8 are fixedly connected, the spring 12 cannot push the telescopic rod 8 to move, thereby maintaining the distance between the circular plate 9 and the side wall of the limit groove 6, so that the two sides of the car radiator can be inserted into the corresponding limit groove 6.

[0032] When the car radiator is inserted into the limiting groove 6, the rotatable pull block 13 drives the end of the limiting rod 100 to rotate from the rotating groove 102 to the transverse groove 101, and the spring 12 can push the push rod to move, thereby driving the circular plate 9 to fix the car radiator.

[0033] See also Figures 1-4 In this embodiment, the circular plate 9 and the side walls of the limiting groove 6 are respectively provided with rubber pads that fit the car radiator.

[0034] In this embodiment, the provision of the rubber pad can prevent damage to the automobile radiator through the cushioning provided by the rubber pad when the automobile radiator is fixed.

[0035] Specifically, when the detection device is actually used, one end of the limit block 5 on which the connecting column 7 is installed is set toward the wind tunnel, thereby avoiding the wind tunnel interfering with the fixing effect of the clamping assembly on the automobile radiator, making the clamping assembly more effective in fixing the automobile radiator.

[0036] See also Figures 1-4 In this embodiment, blocks 200 are provided relatively on the base 1, and a rotatable rotating rod 201 is provided between the blocks 200. The two ends of the rotating rod 201 are extended from the side of the block 200, and the end of the rotating rod 201 extending from the side of the block 200 is provided with a connecting block 202 connected to the connecting plate 2.

[0037] In this embodiment, the block 200, the rotating rod 201 and the connecting block 202 are arranged so that the block 200 is fixedly connected to the base 1, the rotating rod 201 is rotatably connected between the blocks 200 through a bearing, the connecting block 202 is fixedly connected to the rotating rod 201, and the connecting plate 2 is fixedly connected to the connecting block 202. Therefore, when the rotating rod 201 rotates, the connecting plate 2 can be driven to rotate to adjust its inclination angle, so that the connecting plate 2 is rotatably installed above the base 1.

[0038] See also Figures 1-4 In this embodiment, a gear 203 is provided at the center of the rotating rod 201, a moving groove is provided at the center of the base 1, a slidable moving block 204 is provided in the moving groove, and a rack 205 is provided on the moving block 204 that engages with the gear 203. A screw 206 is provided on the outside of the base 1 and extends into the moving groove and is threadedly connected to the moving block 204. A rotating block 207 is provided on the screw 206 for driving the screw 206 to rotate.

[0039] In this embodiment, by setting the gear 203, the movable groove, the movable block 204, the rack 205, the screw 206 and the rotating block 207, the gear 203 is fixedly connected to the rotating rod 201, the rotating block 207 is fixedly connected to the screw 206, the rack 205 is fixedly connected to the movable block 204, the screw 206 is rotatably connected to the base 1 through the bearing, and the screw 206 can be driven to rotate by rotating the rotating block 207. Since the screw 206 is threadedly connected to the movable block 204, the rotation of the screw 206 can drive the movable block 204 moves in the moving groove, and the movement of the moving block 204 can drive the rack 205 to move, and the movement of the rack 205 can drive the gear 203 to rotate, and the rotation of the gear 203 can drive the rotating rod 201 to rotate, thereby driving the connecting plate 2 to rotate, and because the screw 206 and the moving block 204 are threadedly connected, after the rotation angle of the connecting plate 2 is determined, the connecting plate 2 can be prevented from continuing to rotate, so that the angle of the automobile radiator can be adjusted, and then the experimental data of the automobile radiator in multiple directions can be tested.

[0040] When fixing the automobile radiator, the utility model can first pull the pulling block 13 to drive the circular plate 9 to move, so that the distance between the circular plate 9 and the side wall of the limiting groove 6 is increased. When the pulling block 13 cannot be pulled, the pulling block 13 is rotated to drive the end of the limiting rod 100 to rotate from the transverse groove 101 to the rotating groove 102, thereby maintaining the distance between the circular plate 9 and the side wall of the limiting groove 6. Then, the two sides of the automobile radiator are inserted into the corresponding limiting groove 6, and the pulling block 13 is rotated again to rotate the end of the limiting rod 100 from the rotating groove 102 to the transverse groove 101. The spring 12 can push the telescopic rod 8 to move, thereby driving the circular plate 9 to fix the automobile radiator, so that the automobile radiator can be subjected to wind tunnel testing.

[0041] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
