Description

Technical Field

[0001] This utility model relates to the field of automotive fuel tank bracket angle detection, and more specifically, this utility model relates to an automotive fuel tank bracket angle detection device. Background Technology

[0002] In the automotive manufacturing industry, the fuel tank bracket is a key component for securing the fuel tank, and its installation angle directly affects the stability of the fuel tank, vehicle weight distribution, and driving safety. If the bracket angle is off, it may lead to risks such as fuel tank swaying, loose pipe connections, or even fuel leakage. Therefore, the accuracy of the fuel tank bracket angle is a crucial step in the production process.

[0003] Early testing tools were mostly fixed-angle specialized gauges (such as a right-angle ruler fixed at 90 degrees or a custom-made angle template), which could only be used to test a single type of bracket. However, with the diversification of automobile models, the angle design of fuel tank brackets has become more diverse (such as acute angles, obtuse angles, or special angles designed according to the needs of the vehicle body structure). Each angle requires a corresponding set of gauges, resulting in high testing costs, large equipment storage space requirements, and frequent gauge changes that reduce production efficiency.

[0004] Therefore, it is necessary to redesign an automotive fuel tank bracket angle detection device to address the aforementioned issues. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-6 An automotive fuel tank bracket angle detection device includes a first right-angle plate 1 and a second right-angle plate 2. A connecting block 5 is fixedly installed at one end of the first right-angle plate 1. An installation groove 6 is formed on the upper surface of the first right-angle plate 1, and an adjustment device is provided in the installation groove 6. A rotating groove 15 is formed at one end of the second right-angle plate 2. A drive shaft 16 is rotatably installed in the rotating groove 15, and the connecting block 5 is fixedly connected to the outer wall of the drive shaft 16. A connecting shaft 22 is installed at one end of the drive shaft 16, which passes through the inner side wall of the rotating groove 15 and extends outward. A pointer 23 is fixedly installed on the outer wall of the connecting shaft 22. A sliding groove 11 is formed on one side of the second right-angle plate 2, and a transmission device is provided on one side of the sliding groove 11. Two support plates 3 are connected together between the transmission device and the adjustment device. A moving groove 17 is formed on the side of the second right-angle plate 2 away from the sliding groove 11. A slider 19 is slidably connected in the moving groove 17, and a laser rangefinder display 20 is fixedly installed on the slider 19.

[0024] The adjusting device includes a threaded rod 7, which is mounted on the inner wall of the mounting groove 6 via bearings. The threaded rod 7 is threadedly connected to a mounting block 8. Elastic protective membranes 21 are fixedly connected to both sides of the mounting block 8, and the ends of the two elastic protective membranes 21 away from the mounting block 8 are fixedly connected to the inner walls of both sides of the mounting groove 6. The elastic protective membranes 21 expand and contract with the mounting block 8, completely covering the opening of the mounting groove 6, blocking dust and debris from entering, and preventing the threaded parts of the threaded rod 7 and the mounting block 8 from being stuck due to impurities, thus affecting the adjustment accuracy. At the same time, it reduces component wear and extends service life. A first fixing block 9 is fixedly installed on the upper end face of the mounting block 8, and a first fixing shaft 10 is fixedly installed on the first fixing block 9. One end of each of the two support plates 3 is rotatably connected to the two ends of the first fixing shaft 10.

[0025] The transmission device includes a guide rod 12, which is fixedly installed on the inner wall of the slide groove 11. A second fixing block 13 is sleeved on the outer wall of the guide rod 12, and a second fixing shaft 14 is fixedly installed on the second fixing block 13. The ends of two support plates 3 away from the first fixing shaft 10 are respectively rotatably connected to the two ends of the second fixing shaft 14. The two support plates 3 connect the adjustment device and the transmission device, and play a role in force transmission. The two ends of the support plates 3 are rotatably connected to the mounting block 8 and the second fixing block 13 through the first fixing shaft 10 and the second fixing shaft 14, respectively, so that the entire adjustment mechanism can move flexibly, reducing rigid friction between components and extending the service life of the device.

[0026] One end of the threaded rod 7 rotates through the inner wall of the mounting groove 6 and extends outward to install a handle 4.

[0027] A limiting rod 18 is fixedly installed on the inner wall of the moving groove 17, and the slider 19 is slidably sleeved on the outer wall of the limiting rod 18. The moving groove 17, the slider 19, and the limiting rod 18 provide a stable moving and positioning structure for the laser rangefinder reading display 20. The slider 19 slides within the moving groove 17, while the limiting rod 18 restricts the direction of movement of the slider 19, preventing the slider 19 from deviating or rotating during movement, and ensuring that the laser rangefinder reading display 20 can accurately move to the detection position.

[0028] The second right-angle plate 2 has a scale ring 24 on one side that cooperates with the pointer 23. The pointer 23 is fixed on the connecting shaft 22 and rotates synchronously with the transmission shaft 16. The position of the pointer pointing to the scale ring 24 can intuitively reflect the angle between the first right-angle plate 1 and the second right-angle plate 2. The scale of the scale ring 24 is clear and precise, and together with the pointer 23, it realizes the direct reading of the angle, avoiding the complicated conversion process in traditional detection, reducing human reading errors, and improving the efficiency and accuracy of angle detection.

[0029] When using this utility model, rotating the handle 4 causes the threaded rod 7 to rotate within the mounting groove 6 of the first right-angle plate 1. The mounting block 8, which is threadedly connected to the threaded rod 7, moves axially along the mounting groove 6 under the action of the threaded rod 7. The elastic protective membranes 21 on both sides of the mounting block 8 expand and contract accordingly, protecting the inside of the mounting groove 6 and preventing dust from entering the mounting groove 6, thus ensuring that the internal components do not get stuck. When the mounting block 8 moves, it drives the two support plates 3 to swing through the first fixed block 9 and the first fixed shaft 10. The other end of the support plate 3 is connected to the second fixed block 13 through the second fixed shaft 14, which slides along the guide rod 12 in the slide groove 11 of the second right-angle plate 2, thereby pushing the first right-angle plate 1 to rotate around the transmission shaft 16, thereby adjusting the angle between the first right-angle plate 1 and the second right-angle plate 2.

[0030] When the first right-angle plate 1 rotates around the drive shaft 16, the connecting shaft 22 extending from one end of the drive shaft 16 rotates synchronously, and the pointer 23 fixed on the outer wall of the connecting shaft 22 also rotates accordingly. By pointing the pointer 23 to the scale ring 24 on one side of the second right-angle plate 2, the included angle between the first right-angle plate 1 and the second right-angle plate 2 can be read directly, thus completing the intuitive reading of the angle detection.

[0031] The second right-angle plate 2 is located on the side away from the slide groove 11. The slider 19 in the moving groove 17 can slide along the limiting rod 18, and the laser rangefinder display 20 on the slider 19 moves accordingly. By adjusting the position of the slider 19, the laser rangefinder display 20 can measure the relevant distance required in the detection process and display the measurement results, providing auxiliary reference data for angle detection and ensuring the accuracy of the detection.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
