Description

Technical Field

[0001] The utility model belongs to the technical field of measuring instruments, and in particular relates to a device for measuring the sealing gap of a vehicle. Background Art

[0002] As the most commonly used means of transportation for people at this stage, cars provide convenience for people's travel. In the production process of cars, it is necessary to control the sealing gap between the door and the side panel. The sealing gap between the door and the side panel is related to the size of the door opening and closing force, thus affecting the comfort of opening and closing the door.

[0003] The existing patent with announcement number CN220270417U discloses a device for measuring the sealing gap of a vehicle, including an outer door panel and an inner door panel, a displacement sensor is arranged between the outer door panel and the inner door panel, and a waveguide is fixedly arranged at the input end of the displacement sensor; a sensitive element head is slidably arranged on the outer surface of the waveguide, connecting frames are fixedly arranged on both sides of the sensitive element head, and a top pressure plate is fixedly arranged on the side of the connecting frame away from the outer door panel; the side of the top pressure plate away from the outer door panel is in abutment with the side of the inner door panel close to the outer door panel; a suction cup is fixedly arranged on the side of the displacement sensor away from the inner door panel, and the other end of the suction cup is in abutment with the outer door panel.

[0004] The measurement method of the above technical solution is: close the car door, the inner panel of the car door pushes the top pressure plate, and the top pressure plate pushes the sensitive element head. The displacement of the sensitive element head sliding on the surface of the waveguide is sensed by the displacement sensor to determine the density gap between the car door and the side panel. However, after the car door is closed, the fixed pressure plate will be separated from the car door due to inertia, which will cause the displacement sensor to fail to measure normally, resulting in large measurement errors and reduced measurement efficiency.

The bottom of the piston plate 10 is fixedly connected to the top of the first spring 11, and the bottom of the first spring 11 is fixedly connected to the bottom inner wall of the main body 1.

[0025] A displacement sensor 12 is fixedly arranged at the bottom of the cavity of the main body 1 , and the displacement sensor 12 is used to detect the displacement of the piston plate 10 during the vehicle sealing test.

[0026] The outer surface of the main body 1 is rotatably connected to the rotating drum 4, and a display 5 is fixedly arranged on the rotating drum 4. The display 5 is electrically connected to the displacement sensor 12. The display 5 has a built-in power supply and is used to display the data generated by the displacement sensor 12.

[0027] A "T"-shaped limiting block is fixedly arranged on the top of the rotating drum 4, and a "T"-shaped limiting groove is provided at the bottom of the sealing cover 6, and the limiting block is slidably arranged in the limiting groove.

[0028] A clamping mechanism for limiting the position of the pop-up mechanism is provided in the main body 1 .

[0029] The clamping mechanism includes a clamping plate 8, which is arranged in a circular sector shape and the center of the sector shape is located on the central axis of the drum 4. The clamping plate 8 is fixedly arranged on the inner wall of the drum 4. The main body 1 is provided with a second groove 19, which is arranged in a semicircular shape. The clamping plate 8 passes through the second groove 19 and is limitedly slidably engaged with the second groove 19. The end of the clamping plate 8 close to the central axis of the drum 4 is engaged in a limitedly engaged engagement with the tooth groove of the rack 9 on the top plate 7.

[0030] The rotating drum 4 drives the clamping plate 8 to rotate, thereby controlling the clamping plate 8 to disengage from the tooth groove of the rack 9 on the top plate 7. The clamping plate 8 limits the top plate 7.

[0031] A limiting mechanism for limiting the position of the rotating drum 4 is arranged inside the main body 1 .

[0032] The limiting mechanism includes a first clamping block 15, a first groove 16 is provided at the bottom of the main body 1, the first clamping block 15 is slidably arranged in the first groove 16, and the top of the first clamping block 15 is a smooth hemispherical arrangement. The first clamping block 15 is connected to the main body 1 by providing a second spring 17, the top of the second spring 17 is fixedly connected to the bottom of the first clamping block 15, and the bottom of the second spring 17 is fixedly connected to the bottom inner wall of the first groove 16. A second clamping groove 18 is provided at the bottom of the rotating drum 4, and the first clamping block 15 and the second clamping groove 18 are slidably limited.

[0033] In the initial state, the top of the first block 15 is against the bottom of the drum 4, and the second spring 17 is in a compressed state. When the drum 4 is rotated, when the second slot 18 corresponds to the first groove 16, the first block 15 slides upward and is engaged in the second slot 18 under the elastic action of the second spring 17, thereby limiting the position of the drum 4.

[0034] The clamping plate 8 is provided with a third groove 20, in which a second clamping block 22 is slidably disposed, and the second clamping block 22 slides close to or away from the central axis of the drum 4, and the second clamping block 22 is limitedly engaged with the tooth groove on the rack 9. A third spring 21 is disposed between the second clamping block 22 and the clamping plate 8, and the third spring 21 is arranged along the sliding direction of the second clamping block 22, and one end of the third spring 21 is fixedly connected to the second clamping block 22, and the other end is fixedly connected to the inner side wall of the third groove 20.

[0035] The rotating drum 4 drives the clamping plate 8 to rotate, and the clamping plate 8 drives the second clamping block 22 to move, thereby controlling the second clamping block 22 to engage with the rack 9.

[0036] A magnet 3 is fixedly arranged at the bottom of the main body 1, and the magnet 3 is used for adsorbing on the frame.

[0037] How it works

[0038] In the initial state, the clamping plate 8 is engaged with the top plate 7 , and the first spring 11 is in a compressed state.

[0039] During the detection, the magnet 3 at the bottom of the main body 1 is adsorbed on the frame of the vehicle.

[0040] The rotating drum 4 is rotated to drive the clamping plate 8 to rotate along the groove direction of the second groove 19 around the axis of the main body 1, so that the clamping plate 8 and the second clamping block 22 are not in contact with the top plate 7, and the clamping state between the clamping plate 8 and the top plate 7 is released.

[0041] After the engagement between the clamping plate 8 and the top plate 7 is released, the first spring 11 pushes the piston plate 10 to slide upward. The sliding of the piston plate 10 pushes the top plate 7 to slide upward, thereby pushing a part of the top plate 7 out of the interior of the main body 1.

[0042] Then, the rotating drum 4 is rotated, and the rotating drum 4 drives the clamping plate 8 to rotate. The clamping plate 8 drives the second clamping block 22 to rotate, thereby controlling the second clamping block 22 to engage with the rack 9. At this time, the clamping plate 8 and the top plate 7 are still in a disengaged state.

[0043] Since the tooth grooves of the rack 9 are arranged to be tilted downward, when the second clamping block 22 is engaged with the rack 9, the top plate 7 will not slide upward.

[0044] The rotation of the drum 4 will also drive the second slot 18 to rotate, and the second slot 18 will be connected with the first groove 16 during the rotation process.

[0045] When the second clamping block 22 is engaged with the rack 9, the second clamping groove 18 is connected to the first groove 16. At this time, under the elastic action of the second spring 17, the first clamping block 15 will slide away from the second spring 17, so that the smooth surface of the first clamping block 15 is controlled to be engaged in the second clamping groove 18, thereby limiting the rotating drum 4 and preventing the rotating drum 4 from rotating.

[0046] Then, the door is closed, and the door pushes the top plate 7 to slide along the axis of the main body 1 toward the direction close to the inside of the main body 1. The sliding of the top plate 7 pushes the piston plate 10 to slide, and the first spring 11 is compressed downward during the sliding process of the piston plate 10.

[0047] The displacement sensor 12 detects the distance moved by the piston plate 10 and provides a data signal to the display 5 .

[0048] In addition, when the top plate 7 slides toward the inside of the main body 1, the rack 9 will contact and cooperate with the second clamping block 22. When the rack 9 contacts the second clamping block 22, the second clamping block 22 will be controlled to slide in the third groove 20 in a direction away from the top plate 7. Then, under the elastic action of the third spring 21, the second clamping block 22 will slide in a direction close to the top plate 7.

[0049] The second clamping block 22 causes the third spring 21 to be compressed and extended alternately so that the second clamping block 22 can be engaged with the rack 9 .

[0050] Furthermore, when the vehicle door is completely closed, the second block 22 will limit the top plate 7 to reduce the effect of inertia on the sliding of the top plate 7 .

[0051] After the data collection of the device is finished, the rotating drum 4 is rotated to make the clamping plate 8 engage with the rack 9. The device is removed from the frame.

[0052] After removal, the sealing gap size of the vehicle is determined by observing the data on the display 5 or comparing the scale on the top plate 7 .
