[0002] Before the fuel tank leaves the factory, it is often necessary to detect the empty-full oil level of the fuel tank. When workers perform the detection, since the fuel tank needs to be flipped by the workers, flipping by workers consumes a lot of time of the workers. Moreover, during batch detection, installing and disassembling the fuel tank often wastes a lot of time of the workers.

[0003] The patent application number of our country: CN201511003143.9; discloses a fuel tank empty-full oil level resistance detection device and its detection method. The fuel tank is tightly pressed and positioned on the fuel tank rotating plate by the pressure head of the positioning mechanism; the wiring of the multimeter is connected to the fuel tank float wire harness connector to detect the resistance value of the fuel tank in the empty position; rotate the handwheel to flip the fuel tank rotating plate by 180 degrees to detect the resistance value when the fuel tank is full; the fuel tank rotating plate returns to its original position, the positioning mechanism is loosened, the multimeter is disconnected from the fuel tank wiring, and the fuel tank is removed to complete the detection. The detection operation is simple, the detection efficiency is high, and the cost is low.

[0018] Beneficial effects of the present invention:

[0019] The fuel tank empty and full oil level resistance value detection device has four effects through the thrust conversion mechanism. First, the thrust of the slide plate is converted into a resistance force through the thrust conversion mechanism, so that when the slide plate is not pushed further, the slide plate will not be able to move, thereby realizing the left and right fixation of the automobile fuel tank. Second, when the thrust conversion mechanism moves, the pull-down mechanism is pulled to move, so that the clamping mechanism presses the automobile fuel tank on the bracket, thereby completing the upper and lower fixation of the automobile fuel tank. Third, the fixing process of the automobile fuel tank does not require the use of a driving source, thereby reducing the time spent on fixing the automobile fuel tank, reducing the equipment cost, and having high fixing accuracy. Fourth, the blocking mechanism and the rotation release mechanism are driven to move, so that the rotation release mechanism moves to a position where it can be transmitted with the transmission column, and then the blocking mechanism is automatically separated from the rotating baffle, so that the rotating baffle no longer blocks the slide plate, and the slide plate can automatically slide from the rotating guide plate to the inclined guide plate.

[0020] By combining the manual rotating frame, the blocking mechanism and the rotating release mechanism, three effects are achieved. First, by rotating the manual rotating frame, the fuel tank is tilted, so that the automobile fuel tank can slide down, and the automobile fuel tank has a tilting force. Second, during rotation, the rotating release mechanism drives the blocking mechanism to no longer block the rotating baffle, thereby no longer blocking the slide plate, so that the sliding frame can drive the automobile fuel tank to slide down, thereby realizing automatic unloading of the automobile fuel tank. Third, when the slide plate no longer blocks the rotating baffle, the slide plate can automatically slide out of the rotating guide plate, and the worker can quickly determine that the rotating guide plate has rotated to be parallel to the inclined guide plate, which serves as a prompt and warning for the worker.

[0042] Among them, the accompanying drawings are only for illustrative purposes, showing only schematic diagrams, rather than physical diagrams, and should not be construed as a limitation of this patent; in order to better illustrate the embodiments of the present invention, some components in the accompanying drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product.

[0043] Refer to Figures 1 to 10A fuel tank empty / full fuel level resistance detection device shown in the figure includes a manual rotating frame 1, a pressing mechanism 2, two horizontal guide plates 10, an inclined guide plate 12, a rotating guide plate 13, a one-way clamping mechanism 3, a pulling-down mechanism 4, a thrust conversion mechanism 5, a blocking mechanism 6, a rotating release mechanism 7, and several sliding frames for a vehicle fuel tank 11 to be inserted into. The manual rotating frame 1 is fixedly installed on the ground. A rotating plate 1a is provided on the manual rotating frame 1. Two rotating guide plates 13 are fixedly installed at the bottom of the manual rotating frame 1, and strip-shaped notches for the sliding frames to be inserted into are formed inwardly in the two rotating guide plates 13. The cross-sections of the horizontal guide plates 10 and the inclined guide plate 12 are the same as the cross-section of the rotating guide plate 13. The horizontal guide plates 10 are located on the right side of the rotating guide plates 13. The inclined guide plate 12 is inclined and located on the left side of the rotating guide plates 13. The outer sides of the two rotating guide plates 13 are respectively coplanar with the outer sides of the two inclined guide plates 12. The outer sides of the two rotating guide plates 13 are respectively coplanar with the outer sides of the two horizontal guide plates 10. The tops of the two rotating guide plates 13 are coplanar with the tops of the two horizontal guide plates 10. The inclined guide plate 12 and the horizontal guide plates 10 are fixedly installed on the ground through a support frame. The pressing mechanism 2 for pressing the vehicle fuel tank 11 is fixedly installed on the top of the rotating plate 1a. Two one-way clamping mechanisms 3 are fixedly installed on the upper right side of the rotating plate 1a, and the two one-way clamping mechanisms 3 are respectively located directly above the right ends of the two rotating guide plates 13. The two pulling-down mechanisms 4 are respectively located on both sides of the left side of the rotating plate 1a, and the two pulling-down mechanisms 4 are both fixedly installed on the rotating plate 1a. One end of each pulling-down mechanism 4 is in transmission connection with the pressing mechanism 2, and the other end is in transmission connection with the thrust conversion mechanism 5. The two thrust conversion mechanisms 5 are respectively fixedly installed on both sides of the bottom of the rotating plate 1a. Two blocking mechanisms 6 are respectively fixedly installed at the ends of the two thrust conversion mechanisms 5. The thrust conversion mechanism 5 is in transmission connection with the sliding frame. Two rotating release mechanisms 7 are respectively fixedly installed at the bottoms of the two blocking mechanisms 6. The blocking mechanism 6 is in transmission connection with the rotating release mechanism 7. Transmission columns 8 are arranged below the two blocking mechanisms 6. The transmission columns 8 are in transmission connection with the blocking mechanisms 6. The transmission columns 8 are fixedly installed on the ground through support pipes.

[0044] Each sliding frame includes two sliding plates 14 and a clamping frame 15. Each clamping frame 15 is fixedly installed on the two sliding plates 14. The two sliding plates 14 are respectively clamped in the strip-shaped notches of the two rotating guide plates 13. The sliding plates 14 are in transmission connection with the thrust conversion mechanism 5. By providing the clamping frame 15, the vehicle fuel tank 11 can be placed on the clamping frame 15. By a worker pushing the sliding frame, the two sliding plates 14 can slide on the two horizontal guide plates 10, and the sliding plates 14 can be pushed into the rotating guide plates 13.

[0045] Each thrust conversion mechanism 5 includes a rotating baffle 5a, a mounting plate 5b, a first guide plate 5e, a first limiting plate 5f, two first guide posts 5c and a first abutting spring 5d. The first guide plate 5e is fixedly installed at the bottom of the rotating plate 1a. One end of each of the two first guide posts 5c passes through the first guide plate 5e. The first guide plate 5e is provided with guide holes for the first guide posts 5c to pass through. The mounting plate 5b is fixedly installed at one end of the two first guide posts 5c. The first limiting plate 5f is fixedly installed at the other end of the two first guide posts 5c. The two first abutting springs 5d are respectively sleeved on the two first guide posts 5c. One end of each first abutting spring 5d abuts against the first limiting plate 5f, and the other end abuts against the first guide plate 5e. The rotating baffle 5a is located at the top of the mounting plate 5b, and the rotating baffle 5a is hinged to the mounting plate 5b. The rotating baffle 5a is in transmission connection with the blocking mechanism 6, and the mounting plate 5b is in transmission connection with the pulling-down mechanism 4. When the sliding plate 14 is pushed into the rotating guide plate 13, the sliding plate 14 will first push open the one-way clamping mechanism 3. As the sliding plate 14 continues to slide, the sliding plate 14 will contact the rotating baffle 5a. Since the rotating baffle 5a is blocked by the blocking mechanism 6, the rotating baffle 5a will not rotate. A magnet is provided on the back of the rotating baffle 5a, and a magnet is also provided at the position where the blocking mechanism 6 contacts the rotating baffle 5a, so that the rotating baffle 5a always fits on the blocking mechanism 6;

[0046] As the sliding plate 14 is continuously pushed, the sliding plate 14 will push the rotating baffle 5a to move, so that the rotating baffle 5a drives the mounting plate 5b to move, and then the mounting plate 5b drives the first guide post 5c to move, so that the first abutting spring 5d is compressed;

[0047] While the mounting plate 5b is moving, the mounting plate 5b will drive the pulling-down mechanism 4 to move, so that the pulling-down mechanism 4 drives the pressing mechanism 2 to move, and then the pressing mechanism 2 presses on the automobile fuel tank 11. At the same time, the rotating guide plate 13 will slide past the one-way clamping mechanism 3, so that the one-way clamping mechanism 3 limits and clamps one side of the rotating guide plate 13, and the other side of the rotating guide plate 13 will be blocked by the rotating baffle 5a, so that the sliding plate 14 cannot continue to slide, thereby completing the fixation of the automobile fuel tank 11;

[0048] Therefore, the thrust conversion mechanism 5 has four effects. First, the thrust of the slide plate 14 is converted into a resistance force by the thrust conversion mechanism 5, so that when the slide plate 14 is not pushed further, the slide plate 14 will not be able to move, thereby realizing the left and right fixation of the automobile fuel tank 11. Second, when the thrust conversion mechanism 5 moves, the pull-down mechanism 4 is pulled to move, so that the clamping mechanism 2 presses the automobile fuel tank 11 on the bracket 15, thereby completing the upper and lower fixation of the automobile fuel tank 11. Third, the fixing process of the automobile fuel tank 11 does not require the use of a driving source, which reduces the time spent on fixing the automobile fuel tank 11, reduces the equipment cost, and has high fixing accuracy. Fourth, the blocking mechanism 6 and the rotation release mechanism 7 are driven to move, so that the rotation release mechanism 7 moves to a position where it can be transmitted with the transmission column 8, and then the blocking mechanism 6 is automatically separated from the rotating baffle 5a, so that the rotating baffle 5a no longer blocks the slide plate 14, and the slide plate 14 can automatically slide from the rotating guide plate 13 to the inclined guide plate 12.

[0049] The clamping mechanism 2 includes a transmission plate 2d, two pressure plates 2a, four second guide pillars 2b and second resistance springs 2c. The bottoms of the four second guide pillars 2b pass through the rotating plate 1a. The top of the rotating plate 1a is provided with four guide holes for the second guide pillars 2b to pass through. The transmission plate 2d is fixedly mounted on the tops of the four second guide pillars 2b. Each pressure plate 2a is respectively fixedly mounted on the bottoms of two second guide pillars 2b. The four second resistance springs 2c are respectively sleeved on the four second guide pillars 2b. An extension tube 2e is provided on the top of the transmission plate 2d. The two ends of the extension tube 2e are respectively connected to the two pull-down mechanisms 4 in a transmission manner. When the thrust conversion mechanism 5 drives the pull-down mechanism 4 to move, the two pull-down mechanisms 4 will pull the extension tube 2e downward, and the extension tube 2e will drive the transmission plate 2d to move downward, so that the transmission plate 2d pushes the four second guide pillars 2b downward, and the four second guide pillars 2b will push the two pressure plates 2a downward, so that the two pressure plates 2a are pressed tightly on the automobile fuel tank 11, and in the process of the transmission plate 2d moving downward, the transmission plate 2d will compress the second resistance spring 2c to prepare for subsequent reset.

[0050] Each dropdown mechanism 4 includes a drawstring 4a, a runner 4b, and a first rotating column 4c. The first rotating column 4c is fixedly installed on the rotating plate 1a. The runner 4b is rotatably installed on the first rotating column 4c. One end of the drawstring 4a is fixedly installed on the mounting plate 5b. The mounting plate 5b is clamped on the runner 4b. The other end of the drawstring 4a is fixedly connected to the extension tube 2e. A stop post 4d for abutting against the mounting plate 5b is further provided on the first guide plate 5e. When the mounting plate 5b moves, the mounting plate 5b will pull the drawstring 4a to move, causing the drawstring 4a to pull the extension tube 2e to move downward. Thus, when the thrust conversion mechanism 5 moves, it can drive the pressing mechanism 2 to move simultaneously, thereby realizing the fixation of the automotive fuel tank 11. By providing the stop post 4d, a distance is maintained between the mounting plate 5b and the first guide plate 5e, preventing the drawstring 4a from disengaging from the runner 4b.

[0051] Each blocking mechanism 6 includes a resisting plate 6a, a connecting plate 6b, a third guide post 6c, a third abutting spring 6d, a guide seat 6e, and a second limiting plate 6f. The guide seat 6e is fixedly installed at the bottom of the mounting plate 5b. The bottoms of two third guide posts 6c pass through the guide seat 6e. Guide holes for the third guide posts 6c to pass through are provided on the guide seat 6e. The second limiting plate 6f is fixedly installed at the bottoms of the two third guide posts 6c. The connecting plate 6b is fixedly installed at the tops of the two third guide posts 6c. The resisting plate 6a is fixedly installed at the top of the connecting plate 6b. Two third abutting springs 6d are respectively sleeved on the two third guide posts 6c. One end of each third abutting spring 6d abuts against the connecting plate 6b, and the other end abuts against the guide seat 6e. The second limiting plate 6f is in transmission connection with the rotation release mechanism 7. A magnet for adsorbing the rotating baffle 5a is fixedly provided on the resisting plate 6a. When the rotating plate 1a rotates counterclockwise, the rotating guide plate 13 will tilt towards the inclined guide plate 12. During the rotation process, the rotation release mechanism 7 will pull the second limiting plate 6f downward, causing the resisting plate 6a to move downward. Thus, the resisting plate 6a no longer blocks the rotating baffle 5a, enabling the sliding plate 14 to push the rotating baffle 5a to rotate, so that the rotating baffle 5a no longer blocks the sliding plate 14, allowing the sliding plate 14 to slide from the rotating guide plate 13 to the inclined guide plate 12.

[0052] Each rotation release mechanism 7 includes a lower pull plate 7a, a tipping post 7b and a positioning rotating plate 7c. The lower pull plate 7a is fixedly installed at the bottom of the second limiting plate 6f, the positioning rotating plate 7c is fixedly installed at the bottom of the guide seat 6e, the middle of the tipping post 7b is hinged to the positioning rotating plate 7c, one end of the tipping post 7b is inserted into the lower pull plate 7a, a waist-shaped hole for the tipping post 7b to insert is formed on the lower pull plate 7a, and the other side of the tipping post 7b is in contact with the transmission column 8. When the rotating plate 1a rotates counterclockwise, one end of the tipping post 7b will be resisted by the transmission column 8, and the tipping post 7b will rotate along the positioning rotating plate 7c, so that the positioning rotating plate 7c will push the lower pull plate 7a downward, and the lower pull plate 7a will pull the second limiting plate 6f downward, thereby realizing the downward movement of the abutting plate 6a.

[0053] The one-way clamping mechanism 3 includes a second guide plate 3a, a triangular block 3e, a third limiting plate 3f, two heightening tubes 3b, a fourth guide post 3c, and a fourth resisting spring 3d. The two heightening tubes 3b are fixedly installed at the top of the rotating plate 1a, the second guide plate 3a is fixedly installed on the two heightening tubes 3b, the tops of the two fourth guide posts 3c pass through the second guide plate 3a, guide holes for the fourth guide posts 3c to pass through are formed on the second guide plate 3a, the third limiting plate 3f is fixedly installed at the tops of the two fourth guide posts 3c, the triangular block 3e is fixedly installed at the bottoms of the two fourth guide posts 3c, the two fourth resisting springs 3d are respectively sleeved on the two fourth guide posts 3c, and one end of each fourth resisting spring 3d abuts against the second guide plate 3a, and the other end abuts against the triangular block 3e. The bottom of the triangular block 3e passes through the rotating plate 1a, and the bottom end of the triangular block 3e is located in the strip-shaped notch of the rotating guide plate 13. At the beginning, when the sliding plate 14 is about to be inserted into the rotating guide plate 13, the end of the sliding plate 14 will first contact the inclined surface of the triangular block 3e. As the sliding plate 14 continues to move, the sliding plate 14 will push the triangular block 3e upward, so that the triangular block 3e drives the two fourth guide posts 3c to move upward, the fourth resisting spring 3d is compressed, the end of the sliding plate 14 passes through the triangular block 3e, and the bottom of the triangular block 3e abuts against the top of the sliding plate 14. When the sliding plate 14 finishes passing through the triangular block 3e, the fourth resisting spring 3d will push the triangular block 3e downward, so that the flat end of the triangular block 3e contacts the sliding plate 14, thereby realizing the positioning of one side of the sliding plate 14.

The worm 1i is located at the bottom of the turbine 1h. The worm 1i is meshed with the turbine 1h. The worm 1i is fixedly installed on the third rotating column 1j. The third rotating column 1j is fixedly installed on the supporting frame 1e through the rotating seat. The two shaft seats 1f are fixedly installed on the supporting frame 1e. The supporting frame 1e is fixedly installed on the ground. A handle is provided on one end of the third rotating column 1j. When the rotating plate 1a needs to be rotated, the worker turns the handle to make the worm 1i engage and drive the turbine 1h to rotate, and then the turbine 1h drives the second rotating column 1d to rotate, and then the second rotating column 1d drives the rotating plate 1a to rotate through the support tube 1b, so that the rotating plate 1a rotates. First, the rotating plate 1a will rotate clockwise one hundred and eighty degrees, and the worker will use a multimeter to detect the resistance value of the automobile fuel tank 11 when it is unloaded, and then the worker will rotate the rotating plate 1a counterclockwise one hundred and eighty degrees, and the worker will detect the resistance value when it is fully loaded. When the detection is completed, the automobile fuel tank 11 is rotated counterclockwise by a preset angle to make it slide tiltably from the rotating guide plate 13 to the inclined guide plate 12. Of course, the motor can be controlled instead of the worker to rotate the handle.

[0055] Working principle: First, workers place the sliding frame on the horizontal guide plate 10, then workers place the automobile fuel tank 11 on the sliding frame, and then the equipment or workers push the sliding frame.

[0056] When the slide plate 14 is pushed into the rotating guide plate 13, the slide plate 14 will first push open the one-way clamping mechanism 3. As the slide plate 14 continues to slide, the slide plate 14 will contact the rotating baffle 5a. Since the rotating baffle 5a is blocked by the blocking mechanism 6, the rotating baffle 5a will not rotate. A magnet is provided on the back of the rotating baffle 5a, and a magnet is also provided at the position where the blocking mechanism 6 contacts the rotating baffle 5a, so that the rotating baffle 5a is always attached to the blocking mechanism 6.

[0057] As the slide plate 14 continues to push, the slide plate 14 will push the rotating baffle plate 5a to move, so that the rotating baffle plate 5a drives the mounting plate 5b to move, and then the mounting plate 5b drives the first guide column 5c to move, so that the first resisting spring 5d is compressed;

[0058] When the mounting plate 5b moves, the mounting plate 5b will pull the drawstring 4a to move, so that the drawstring 4a pulls the extension tube 2e downward, so that the thrust conversion mechanism 5 can simultaneously drive the clamping mechanism 2 to move, so that the clamping mechanism 2 is pressed against the automobile fuel tank 11, and at the same time, the rotating guide plate 13 will slide over the one-way clamping mechanism 3, so that the one-way clamping mechanism 3 limits and clamps one side of the rotating guide plate 13, and the other side of the rotating guide plate 13 will be blocked by the rotating baffle 5a, so that the slide plate 14 cannot continue to slide, thereby completing the fixing of the automobile fuel tank 11;

[0059] Then the worker turns the handle, so that the worm 1i meshes and drives the turbine 1h to rotate, and then the turbine 1h drives the second rotating column 1d to rotate, and then the second rotating column 1d drives the rotating plate 1a to rotate through the support tube 1b, so that the rotating plate 1a rotates. First, the rotating plate 1a rotates 180 degrees clockwise, and the worker uses a multimeter to detect the resistance value of the automobile fuel tank 11 when it is unloaded. Then, the worker rotates the rotating plate 1a 180 degrees counterclockwise, and the worker detects the resistance value when it is fully loaded.

[0060] When the detection is completed, it is rotated counterclockwise to a preset angle. During the rotation process, since the rotating plate 1a rotates counterclockwise, one end of the tilting column 7b will be resisted by the transmission column 8, and the tilting column 7b will rotate along the positioning rotating plate 7c, so that the positioning rotating plate 7c will push the pull-down plate 7a downward, so that the pull-down plate 7a pulls the second limiting plate 6f downward, so that the resisting plate 6a moves downward, and then the resisting plate 6a no longer blocks the rotating baffle plate 5a, so that the slide plate 14 can push the rotating baffle plate 5a to rotate, so that the rotating baffle plate 5a no longer blocks the slide plate 14, so that the slide plate 14 can slide from the rotating guide plate 13 to the inclined guide plate 12;

[0061] The workers repeat the above process again, and then continuously test all the automobile fuel tanks 11.
