Description

Technical Field

[0001] This utility model relates to the field of automotive testing equipment technology, specifically to a fixture for fixing an impact head for automotive steering wheel impact testing. Background Technology

[0002] The steering wheel is one of the most crucial components in car driving. As the link between the driver and the vehicle, the performance and quality of the steering wheel directly affect driving safety and comfort. To ensure the reliability and safety of the steering wheel, manufacturers and relevant organizations typically conduct a series of tests. The steering wheel withstands enormous impact forces during a vehicle collision, making crash testing essential for its safety performance. Crash tests usually use equipment that simulates collisions, such as impact test benches, to simulate different types of collision scenarios and evaluate the steering wheel's performance in a crash. These tests ensure that the steering wheel possesses sufficient impact resistance to provide better protection for the driver in a collision.

[0003] Existing fixtures typically use pressure rods or push rods to fix the product being tested, which results in unreliable positioning and a tendency for loosening during positioning, thus affecting the accuracy of steering wheel testing. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an impact head fixing fixture for automotive steering wheel impact testing, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: an impact head fixing fixture for automotive steering wheel impact testing, including a bracket and a wall, and a slide rail fixedly installed on the top of the bracket. A slider is slidably installed at the end of the slide rail away from the bracket. A fixing plate is fixedly installed by screws at the end of the slider away from the slide rail. A guide post is fixedly installed at the center of the end of the fixing plate away from the wall. A connecting component is provided at the center of the fixing plate. A power component is provided between the bracket and the wall.

[0006] The connecting assembly includes a first mounting plate, a groove, a positioning hole, a knob, a second mounting plate, a mounting groove, a protrusion, mounting screws, and a mounting nut. The outer surface of the fixing plate is provided with the first mounting plate and the second mounting plate, which are fixedly installed by the mounting screws and the mounting nut. The first mounting plate has a groove near the second mounting plate, the first mounting plate has a positioning hole at the end away from the second mounting plate, the first mounting plate has a knob at the end away from the second mounting plate, the second mounting plate has mounting grooves at both ends, and the top of the second mounting plate near the first mounting plate is fixedly installed with a protrusion.

[0007] Preferably, the connecting assembly has a connector at one end near the wall, a slot at one end near the slide rail, a connecting post one fixedly installed at the end of the connector away from the connecting assembly, a baffle fixedly installed on the outer surface of the connecting post one away from the connector, a locking block at one end of the connecting assembly away from the connector, an insert block fixedly installed at one end of the locking block near the connector, a limiting hole for insertion into the insert block at one end away from the connecting assembly, the insert pin being able to be inserted into the interior of the connecting assembly through the limiting hole, a connecting frame at one end of the baffle near the wall, mounting holes for sliding connection with the connecting post one at both ends of the connecting frame, a connecting post two fixedly installed at both ends of the connecting frame, an impact head at one end of the connecting assembly near the wall, a connecting groove for fixed connection with the connecting post one and the connecting post two at the inside of the impact head near the connecting assembly, a fixing seat one fixedly installed at the center of the bottom of the fixing plate, and a steering wheel fixedly installed at one end of the wall near the fixing plate.

[0008] Through the above technical solution, by setting a sliding connection between the connecting frame and the first connecting column, the connecting frame and the connecting parts can be quickly installed. Then, by inserting the connecting groove on the impact head into the first and second connecting columns, it is convenient for the staff to quickly install the impact head on the outside of the connecting frame and the connecting parts. When the staff installs the connecting parts and the locking block into the connecting assembly, they can insert the pin into the limiting hole and extend into the inside of the connecting assembly, thus achieving a fixed installation of the connecting parts and preventing instability during testing from causing inaccurate test results.

[0009] Preferably, the connector and the mounting groove are slidably connected, the plug and the slot are plugged in, and the locking block and the mounting groove are slidably connected.

[0010] With the above technical solution, and by designing a sliding connection between the connector and the mounting slot, when installing the connector, the operator only needs to align one end of the connector with the mounting slot and insert it to achieve quick installation. Then, the operator aligns the locking block with the mounting slot and inserts it. At this time, the locking block is inserted into the slot, which further improves the connection strength between the connector and the connecting component.

[0011] Preferably, the inner diameter of the mounting hole is the same as the outer diameter of the first connecting column, the radius of the baffle is greater than the radius of the first connecting column, the first connecting column and the second connecting column have the same radius, and the cross-section of the connecting frame is a cross-shaped structure.

[0012] Through the above technical solution, the connecting frame can be quickly installed on the outside of the connecting part by sliding the connecting frame and the connecting column one. Then, the connecting frame can be limited by the radius of the baffle being larger than the radius of the connecting column one. By setting the cross section of the connecting frame to be a "+" shaped structure, and with the two sets of connecting columns one and two sets of connecting columns two connected to the impact head at the same time, the stability of the impact head during the impact test is improved.

[0013] Preferably, the protrusion and the groove are plug-in installed, the positioning hole and the guide post have the same radius, and the guide post and the positioning hole are plug-in installed.

[0014] With the above technical solution, when installing the connecting components, the staff can first install the first mounting plate on the outside of the fixed plate by using the guide post and positioning hole for plug-in installation. Then, the staff can quickly assemble and connect the first mounting plate and the second mounting plate by using the protrusion and groove for plug-in installation. Finally, the connecting components can be quickly fixed by using the installation screws and nuts, which improves the installation efficiency and reduces the installation difficulty.

[0015] Preferably, the power assembly includes a drive motor, a take-up roller, a power line, a second fixed base, a fixed pulley, and a limiting block. The drive motor is fixedly installed on the top of the inner side of the bracket, the take-up roller is fixedly installed on the output shaft of the drive motor, one end of the power line is fixedly installed on the inner side of the take-up roller, the second fixed base is fixedly installed on a section of the wall near the fixed plate, the fixed pulley is provided on the side of the second fixed base near the fixed plate, and the limiting block is fixedly installed on the other end of the power line.

[0016] The above technical solution incorporates a power component, which provides power to the device. By controlling the rotational speed of the drive motor, the impact speed can be controlled, thereby achieving the impact effect of the impact head on the steering wheel at different speeds.

[0017] Preferably, one end of the power line is fixedly connected to the take-up roller, the other end of the power line is fixedly connected to the limiting block, the power line is slidably connected to the fixed seat, the radius of the limiting block is larger than the radius of the power line, and the power line is rotatably connected to the fixed pulley.

[0018] The above technical solution allows for the limitation of the power line by making the radius of the limiting block larger than the radius of the power line. When the drive motor is started, the output shaft of the drive motor drives the take-up roller to retract the power line through the rotational connection between the power line and the fixed pulley. At this time, the limiting block abuts against the fixed seat, and with the guiding action of the slider and the slide rail, the impact head is moved towards the wall, thereby realizing the impact test on the steering wheel.

[0019] Compared with the prior art, this utility model provides an impact head fixing fixture for automotive steering wheel impact testing, which has the following beneficial effects:

[0020] 1. This impact head fixing fixture for automotive steering wheel impact testing is designed for insertion and installation using guide posts and positioning holes. The first mounting plate can be installed on the outside of the fixing plate first, and then the protrusion and groove are designed for insertion and installation. This allows the operator to quickly assemble and connect the first mounting plate and the second mounting plate. Then, the connecting components can be quickly fixed by mounting screws and mounting nuts, which improves installation efficiency and reduces installation difficulty.

[0021] 2. This impact head fixing fixture for automotive steering wheel impact testing features a sliding connection between the connector and the mounting slot. When installing the connector, the operator simply aligns one end of the connector with the mounting slot and inserts it to quickly install the connector and the connecting assembly. Then, the operator aligns the locking block with the mounting slot and inserts it. At this point, the block is perfectly inserted into the slot. Inserting the pin into the limiting hole further enhances the connection strength between the connector and the connecting assembly. The connecting bracket can be quickly installed on the outside of the connector through a sliding connection between the connecting frame and connecting post one. The cross-section of the connecting frame is designed in a "+" shape, which improves the stability of the impact head during impact testing when both sets of connecting posts one and two sets of connecting posts two are simultaneously connected to the impact head.

[0031] 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.

[0032] Example 1:

[0033] like Figure 1-8 As shown, this utility model provides an impact head fixing fixture for automotive steering wheel impact testing. The impact head fixing fixture for automotive steering wheel impact testing includes a bracket 1, a wall 2, and a slide rail 3 fixedly installed on the top of the bracket 1. A slider 4 is slidably installed at the end of the slide rail 3 away from the bracket 1. A fixing plate 5 is fixedly installed by screws at the end of the slider 4 away from the slide rail 3. A guide post 6 is fixedly installed at the center of the end of the fixing plate 5 away from the wall 2. A connecting component 7 is provided at the center of the fixing plate 5. A power component 23 is provided between the bracket 1 and the wall 2.

[0034] The connecting assembly 7 includes a mounting plate 701, a groove 702, a positioning hole 703, a knob 704, a mounting plate 705, a mounting groove 706, a protrusion 707, a mounting screw 708, and a mounting nut 709. The outer surface of the fixing plate 5 is provided with mounting plate 701 and mounting plate 705, which are fixedly installed by mounting screw 708 and mounting nut 709. Mounting plate 701 has a groove 702 near mounting plate 705. Mounting plate 701 has a positioning hole 703 at the end away from mounting plate 705. Mounting plate 701 has a knob 704 at the end away from mounting plate 705. Mounting groove 706 is provided at both ends of mounting plate 705. A protrusion 707 is fixedly installed on the top of the section of mounting plate 705 near mounting plate 701.

[0035] Specifically, a connector 8 is provided at the end of the connecting component 7 near the wall 2, and a slot 9 is provided at the end of the connector 8 near the slide rail 3. A connecting post 10 is fixedly installed at the end of the connector 8 away from the connecting component 7. A baffle 11 is fixedly installed on the outer surface of the side of the connecting post 10 away from the connector 8. A locking block 12 is provided on the side of the connecting component 7 away from the connector 8, and an insert block 13 is fixedly installed at the end of the locking block 12 near the connector 8. A limiting hole 14 is provided at the end of the insert block 13 away from the connecting component 7 for insertion and installation with a pin 15. The pin 15 can be inserted into the connecting component through the limiting hole 14. Inside component 7, a connecting bracket 16 is provided at one end of baffle 11 near wall 2. The two ends of the connecting bracket 16 are provided with mounting holes 17 that are slidably connected to connecting post 10. The two ends of the connecting bracket 16 are fixedly installed with connecting post 28. An impact head 19 is provided on one side of connecting component 7 near wall 2. The inside of the impact head 19 is provided with a connecting groove 20 that is fixedly connected to connecting post 10 and connecting post 28 on one side of connecting component 7. A fixing seat 21 is fixedly installed at the center of the bottom of fixing plate 5. A steering wheel 22 is fixedly installed on one end of wall 2 near fixing plate 5. The advantage is that by setting the sliding connection between the connecting frame 16 and the first connecting post 10, the connecting frame 16 and the connecting piece 8 can be quickly installed. Then, by inserting the connecting groove 20 on the impact head 19 into the first connecting post 10 and the second connecting post 18, it is convenient for the staff to quickly install the impact head 19 on the outside of the connecting frame 16 and the connecting piece 8. When the staff installs the connecting piece 8 and the locking block 12 into the connecting assembly 7, they can insert the pin 15 into the limiting hole 14 and extend it into the interior of the connecting assembly 7 to achieve the fixed installation of the connecting piece 8 and prevent instability during testing from causing inaccurate test results.

[0036] Specifically, the connector 8 is slidably connected to the mounting groove 706, the insert block 13 is plugged into the slot 9, and the locking block 12 is slidably connected to the mounting groove 706. The advantage is that, with the slidably connected connector 8 to the mounting groove 706, when installing connector 8, the operator only needs to align one end of connector 8 with the mounting groove 706 and insert it to achieve quick installation. Then, the operator aligns the locking block 12 with the mounting groove 706 and inserts it. At this point, the insert block 13 is inserted into the slot 9, further improving the connection strength between connector 8 and connecting assembly 7.

[0037] Specifically, the inner diameter of the mounting hole 17 is the same as the outer diameter of the connecting post 10, the radius of the baffle 11 is larger than the radius of the connecting post 10, the radii of the connecting post 10 and the connecting post 18 are the same, and the cross-section of the connecting frame 16 is a cross shape. The advantage is that the connecting frame 16 can be quickly installed on the outside of the connector 8 by sliding the connecting frame 16 to the connecting post 10. Subsequently, the radius of the baffle 11, being larger than the radius of the connecting post 10, can limit the movement of the connecting frame 16. By setting the cross-section of the connecting frame 16 to a cross shape, and with both sets of connecting posts 10 and 18 simultaneously connected to the impact head 19, the stability of the impact head 19 during impact testing is improved.

[0038] Example 2:

[0039] like Figure 2-8 As shown, as an improvement over the previous embodiment, to facilitate the rapid assembly of the connecting component 7, specifically, the protrusion 707 and the groove 702 are plug-in installed, the positioning hole 703 has the same radius as the guide post 6, and the guide post 6 and the positioning hole 703 are plug-in installed. The advantage is that when installing the connecting component 7, the worker can first install the mounting plate 701 on the outside of the fixing plate 5 by using the plug-in design of the guide post 6 and the positioning hole 703. Then, by using the plug-in design of the protrusion 707 and the groove 702, the worker can quickly assemble and connect the mounting plate 701 and the mounting plate 705. Finally, the connecting component 7 can be quickly fixed by the mounting screws 708 and the mounting nuts 709, improving installation efficiency while reducing installation difficulty.

[0040] Specifically, the power assembly 23 includes a drive motor 2301, a take-up roller 2302, a power line 2303, a second fixed base 2304, a fixed pulley 2305, and a limiting block 2306. The drive motor 2301 is fixedly mounted on the top inner side of the bracket 1. The take-up roller 2302 is fixedly mounted on the output shaft of the drive motor 2301. One end of the power line 2303 is fixedly mounted on the inner side of the take-up roller 2302. The second fixed base 2304 is fixedly mounted on one end of the wall 2 near the fixed plate 5. A fixed pulley 2305 is provided on the side of the second fixed base 2304 near the fixed plate 5. The other end of the power line 2303 is fixedly mounted with the limiting block 2306. The advantage is that the power assembly 23 provides power to the device, and the impact speed can be controlled by adjusting the rotational speed of the drive motor 2301, thus achieving the impact effect of the impact head 19 on the steering wheel 22 at different speeds.

[0041] Specifically, one end of the power line 2303 is fixedly connected to the take-up roller 2302, and the other end is fixedly connected to the limiting block 2306. The power line 2303 is slidably connected to the fixed seat 21. The radius of the limiting block 2306 is larger than the radius of the power line 2303. The power line 2303 is rotatably connected to the fixed pulley 2305. The advantage is that by limiting the radius of the limiting block 2306, the power line 2303 can be limited. When the drive motor 2301 is started, the output shaft of the drive motor 2301 drives the take-up roller 2302 to retract the power line 2303 through the rotatable connection between the power line 2303 and the fixed pulley 2305. At this time, the limiting block 2306 abuts against the fixed seat 21. Combined with the guiding action of the slider 4 and the slide rail 3, the impact head 19 is displaced towards the wall 2, thereby achieving an impact test on the steering wheel 22.

[0042] Working Principle: In use, the operator uses the guide post 6 and positioning hole 703 for plug-in installation. First, mounting plate 701 is installed on the outside of fixing plate 5. Then, using the protrusion 707 and groove 702 for plug-in installation, the operator can quickly assemble mounting plate 701 and mounting plate 705. The connecting component 7 is then quickly fixed using mounting screws 708 and mounting nuts 709, improving installation efficiency and reducing installation difficulty. Next, the connector 8 and mounting groove 706 are slidably connected. When installing connector 8, the operator only needs to align one end of connector 8 with the mounting groove 706 and insert it to quickly install connector 8 and connecting component 7. Then, the operator aligns locking block 12 with the mounting groove 706 and inserts it. At this point, insert block 13 is inserted into slot 9, further improving the connection strength between connector 8 and connecting component 7. Finally, the connecting bracket 16 is slidably connected to connecting post 10, allowing for quick installation of the connecting bracket 16. Installed on the outside of connector 8, and with the radius of baffle 11 being larger than that of connecting post 10, the connecting frame 16 can be limited. By setting the cross-section of connecting frame 16 to a "+" shape, the stability of impact head 19 during impact testing is improved when both sets of connecting posts 10 and 18 are simultaneously connected to impact head 19. Then, drive motor 2301 is started, and the output shaft of drive motor 2301 drives take-up roller 2302 to rotate, thereby winding up power line 2303. By rotating the power line 2303 and the fixed pulley 2305, the power line 2303 at one end of the fixed seat 21 can be wound up. At this time, since the radius of the limiting block 2306 is larger than the radius of the power line 2303, the limiting block 2306 will abut against the fixed seat 21, thereby providing a force for the fixed plate 5 to move towards the wall 2. By controlling the speed of the drive motor 2301, the speed during the impact can be controlled, thereby achieving the impact effect of the impact head 19 on the steering wheel 22 at different speeds.

[0043] 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.
