Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing technology and relates to a front suspension fixing device for static stiffness of body-in-white. Background Technology

[0002] In automobile manufacturing, static stiffness testing of the body-in-white is a crucial step in ensuring the strength and rigidity of the vehicle body structure. Existing front suspension mounting devices are typically complex in structure, inconvenient to install and disassemble, and difficult to adapt to the testing requirements of different vehicle models. Therefore, it is necessary to design a front suspension mounting device for body-in-white static stiffness testing that is simple in structure, easy to install, and highly adaptable.

[0003] Patent document CN216207393U provides a static stiffness testing fixture for vibration isolation pads. The static stiffness testing fixture for vibration isolation pads includes a base, a loading device, and a sensor. It is mainly used to apply load to vibration isolation pads and measure the deformation. It has a single function and is mainly used to perform static stiffness testing on small components.

[0004] Difference: The former has a simple structure and single function; the latter can adapt to the testing needs of different vehicle models and can ensure a firm fixation and convenient adjustment.

[0005] Patent document CN118618498A provides a vehicle body structure and automobile for improving the rigidity of the side outer panel. The vehicle body structure for improving the rigidity of the side outer panel is fixed to the CD pillar assembly by the rear wheel cavity rubber block, realizing the soft connection between the side outer panel and the CD pillar assembly, providing Y-direction support to the side outer panel. It has a small load-bearing capacity and is mainly used for testing small parts.

[0006] Difference: The former has a small load-bearing capacity and the test object is light; the front suspension fixing device for static stiffness of the body-in-white in this application has a large load-bearing capacity and the test object is heavy, and can support the front suspension of the entire body-in-white.

[0007] Patent document CN215865706U provides a general-purpose loading device for testing the stiffness of the hinge fixing point of an automobile engine hood. However, the three-point fixing point has limited adjustment function and poor adaptability, making it difficult to adapt to parts of different sizes or shapes.

[0008] Difference: The former has limited adjustment capabilities and poor adaptability; this application has a high degree of adjustment and a multi-hole fixing design, making it highly adaptable. Summary of the Invention

[0009] The purpose of this invention is to provide a front suspension fixing device for static stiffness of a body-in-white that is simple in structure, easy to install, and highly adaptable.

[0011] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0012] A static stiffness front suspension fixing device for a body-in-white includes a base base 1, a base shaft 2, a short round column 3, a column 4, a fisheye head 5, and a locking block 6.

[0013] The base 1 is connected to the base shaft 2, the short round column 3 is connected to the base shaft 2 by a thread, the column 4 is connected to the short round column by a thread, the fisheye head 5 is connected to the column 4 by a thread, and the locking block 6 is connected to the fisheye head 5 by a pin.

[0014] The base shaft 2 has a shaft 21 at its lower part. The shaft 21 is confined in two cylindrical holes on the base base 1. The shaft 21 is rotated to adjust the relative position between the base base 1 and the base shaft 2.

[0015] Furthermore, the base 1 consists of two main parts: a U-shaped base 11 and two identical symmetrical blocks 12. Each of the two symmetrical blocks has a semi-circular arc, which, together with the two semi-circular arcs on the U-shaped base 11, forms two cylindrical holes. The U-shaped base 11 and the symmetrical blocks 12 are fixed together by bolts.

[0016] Furthermore, the shaft 21 at the lower part of the base shaft 2 is placed into the two cylindrical holes of the base base 1. After the U-shaped base 11 and the symmetrical block 12 are fixed by bolts, the shaft 21 is restricted in the two cylindrical holes. The shaft 21 is rotated to adjust the relative position of the base base 1 and the base shaft 2.

[0017] Furthermore, pins 22 are provided on both sides of the shaft 21 at the lower part of the base shaft 2; the pins 22 are used to restrict the degree of freedom of the shaft 21.

[0018] Furthermore, the upper part of the base shaft 2 is provided with a disc 23, and the disc 23 is provided with a threaded hole for connecting with the short cylindrical column 3.

[0019] Furthermore, the short round column 3 is provided with an internal hexagonal hole 31 at the bottom, which is used to fix the short round column 3 to the base shaft 2. The internal hexagonal bolt passes through the internal hexagonal hole 31 and is tightened and fixed with the threaded hole of the disc 23 of the base shaft 2.

[0020] Furthermore, the fisheye head 5 is fixed to the locking block 6 by a pin; two small steel plates are provided between the locking block 6 and the fisheye head 5 for fastening the fisheye head 5.

[0021] Furthermore, a gasket is provided between the locking block 6 and the body-in-white; the locking block 6 is provided with a plurality of fixing holes arranged in a matrix.

[0022] Furthermore, the lower part of the base 1 is connected to and fixed to the static stiffness front suspension platform.

[0023] Furthermore, the static stiffness front suspension fixing device of the body-in-white is made of high-strength steel or aluminum alloy.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. Traditional static stiffness fixing devices are not adjustable in direction during the installation of the base, making installation complicated; however, the static stiffness front suspension fixing device for the body-in-white of this utility model is adjustable in direction through the intermediate shaft when installing the base, reducing test errors, and at the same time, there are two pins used to fix the intermediate shaft to restrict its degree of freedom.

[0026] 2. Traditional static stiffness fixing devices cannot be height-adjusted when installing a cylindrical object, but the front suspension fixing device of this utility model can be height-adjusted via threads to adapt to different vehicle models.

[0027] 3. Traditional static stiffness fixing devices have excessively large gaps when connected to the body-in-white. However, the front suspension fixing device of this utility model reduces the gaps by connecting the locking mechanism to the spherical head, thus making the test results more accurate.

[0047] The present invention will now be described in detail with reference to the accompanying drawings:

[0048] This invention addresses the problems existing in existing body-in-white static stiffness testing devices by designing a front suspension fixing device for body-in-white static stiffness testing. This front suspension fixing device adopts a modular assembly method, which is convenient for installation and maintenance. The base shaft is fixed, so it will not shake during the test due to the weight of the body-in-white, thus affecting the test results. At the same time, there are two pins above the base shaft to fix its degree of freedom and prevent it from turning arbitrarily, ensuring the accuracy of the test. In addition, three M10 hex sockets are used above to fix the body-in-white and the front suspension fixing device, ensuring safety.

[0049] The technical solution adopted to realize this utility model is as follows: Figure 1 , Figure 2 , Figure 3 As shown, a front suspension fixing device for a white body includes: a base base 1, a base shaft 2, a short round column 3, a column 4, a fisheye head 5, and a locking block 6.

[0050] The base 1 and the base shaft 2 are connected by hex bolts. The short round column 3 is fixed to the base shaft 2 by a threaded connection. The column 4 is fixed to the short round column 3 by a threaded connection. The fisheye head 5 is fixed to the column 4 by a threaded connection. The locking block 6 is fixed to the fisheye head 5 by a pin connection.

[0051] The base 1 and the base shaft 2 are connected and fixed by hexagon socket bolts, which ensures the strength of the overall front suspension fixed structure and reduces the weight of the device. The lower part of the base 1 is connected to the static stiffness front suspension platform for fixation. The base direction can be adjusted through the base shaft 2 in the middle to meet the convenience of testing in different environments. At the same time, there are two pins 22 on the base shaft 2 to restrict the degree of freedom of the shaft 21, which can ensure that the device will not move during the test and ensure the stability of the device during the test.

[0052] like Figure 4 As shown, the base 1 consists of two main parts: a U-shaped base 11 and two identical symmetrical blocks 12. Each of the two symmetrical blocks has a semi-circular arc, which, together with the two semi-circular arcs on the U-shaped base 11, forms two cylindrical holes. The U-shaped base 11 and the symmetrical blocks 12 are fixed together by bolts.

[0053] like Figure 5 As shown, the lower part of the base shaft 2 is provided with a shaft 21, and the two sides of the shaft are respectively provided with pins 22; the upper part of the base shaft 2 is provided with a disc 23, and the disc 23 is provided with a threaded hole for connecting with the short round column 3.

[0054] The shaft 21 at the bottom of the base shaft 2 is placed into the two cylindrical holes of the base base 1. After the U-shaped base 11 and the symmetrical block 12 are fixed by bolts, the shaft 21 is restricted in the two cylindrical holes. The shaft 21 can be rotated to adjust the relative position of the base base 1 and the base shaft 2, but the two pins 22 restrict the degree of freedom of the shaft 21.

[0055] Four M8 hexagon socket holes are machined on the bottom of the short round column 3 to fix the short round column 3 to the base shaft 2, ensuring the stability of the short round column 3. The hexagon socket bolts pass through the hexagon socket holes and are tightened into the threaded holes of the disc 23 of the base shaft 2.

[0056] The cylinder 4 is fixed to the short cylindrical column 3 by threads, and the height can be adjusted by the threaded connection to adapt to different vehicle models;

[0057] The fisheye head 5 is fixed to the cylinder 4 by a threaded connection;

[0058] An M10 pin passes through the spherical head 5 and the locking block 6, and the spherical head 5 and the locking block 6 are fixed by the pin; between the locking block 6 and the body-in-white, there is a round three-hole pad fixed to the body-in-white with three M10 hex sockets. At the same time, the locking block 6 and the spherical head 5 are clamped by two small steel plates, which helps to fix the spherical head 5, prevents it from moving around, and reduces the gap between the body-in-white and the front suspension fixing device.

[0059] This invention uses high-strength steel or aluminum alloy materials to improve the rigidity and durability of the front suspension fixing device. These materials have a higher strength-to-weight ratio, reducing weight while enhancing structural stability.

[0060] This utility model device adopts an innovative structure. Its direction is adjustable via a base shaft, while two screw pins restrict rotational freedom. The tap connecting the device to the base is height-adjustable to accommodate different heights and includes a locking block. The device features a threaded connection, allowing for base height adjustment to adapt to different vehicle front suspension structures. The base and locking block have multiple fixing holes arranged in a matrix, further enhancing adaptability. The device's spherical head connects to the locking block, reducing gaps and resulting in more accurate test data.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in this utility model, and within the spirit and principles of this utility model, should be included within the protection scope of this utility model. Furthermore, all content not described in detail in this specification belongs to the prior art known to those skilled in the art.
