[0030] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.
[0031] See also Figure 1-6 An air spring body mounting structure shown includes an air spring upper cover 1, a body 2, an upper mounting seat 3 and a body fastener 4; wherein the body 2 has a locking groove 21; wherein the upper mounting seat 3 is arranged on the air spring upper cover 1; the upper mounting seat 3 has an installation space 31; wherein the body fastener 4 includes a mounting seat mating block 41 arranged at the lower end and a deformable locking hook 42 arranged at the upper end; the mounting seat mating block 41 is detachably connected to the installation space 31, and the deformable locking hook 42 is detachably connected to the locking groove 21 so as to limit the movement of the air spring upper cover 1.
[0032] In actual use, the utility model provides a locking groove 21 on the vehicle body 2, an upper mounting seat 3 on the air spring upper cover 1, and a vehicle body fastener 4. The vehicle body fastener 4 cooperates with the installation space 31 of the upper mounting seat 3 through the mounting seat matching block 41, and cooperates with the locking groove 21 of the vehicle body 2 through the deformable locking hook 42. The assembly is relatively convenient, and the air spring and the vehicle body 2 are fixed through the air spring upper cover 1, thereby avoiding the air spring from falling from the lower swing arm; the vehicle body fastener 4 is detachably connected to the vehicle body 2 and the upper mounting seat 3, so that after the air spring is installed, the vehicle body fastener 4 can be removed and used for the installation of the next air spring, thereby reducing the cost.
[0033] Please continue reading Figure 3, wherein the deformable locking hook 42 includes a center column 421 and a deformable block 422 arranged on at least one side of the center column 421; there is a deformation space 423 between the center column 421 and the deformable block 422; in the process of the deformable locking hook 42 passing through the locking groove 21, the deformable block 422 is deformed toward the deformation space 423; after passing through the locking groove 21, the deformable block 422 applies a force to the locking groove 21 to fix the body fastener 4 to the body 2.
[0034] Specifically, the middle column 421 is used as a carrier to carry the deformable block 422. Therefore, when a deformable block 422 is provided on the middle column 421, the deformation function can be realized, that is, it passes through the locking groove 21 by deformation and applies a force to the locking groove 21 by rebounding; in order to balance the forces on both sides of the middle column 421, a deformable block 422 can be provided on one side of the middle column 421, and a non-deformable buckle portion can be provided on the other side to cooperate with the locking groove 21.
[0035] It is understandable that the number of the deformable blocks 422 on the center column 421 may also be two, four or more so as to cooperate with the locking groove 21 from multiple directions.
[0036] Please continue reading Figure 3 , wherein the deformable block 422 includes an oblique guide portion 4221 arranged on the center pillar 421, a convex buckle portion 4222 arranged at the lower end of the oblique guide portion 4221, and a side pressing portion 4223 arranged at the lower end of the convex buckle portion 4222; the convex buckle portion 4222 and the side pressing portion 4223 act on the vehicle body 2 respectively.
[0037] When the deformable locking hook 42 passes through the locking groove 21, the oblique guide portion 4221 is used to contact and cooperate with the lower end of the locking groove 21 so as to guide the deformable block 422 to deform toward the deformation space 423; the convex buckle portion 4222 and the side extrusion portion 4223 act on the vehicle body 2 from two different directions respectively, so that the connection between the deformable locking hook 42 and the vehicle body 2 is more secure.
[0038] Please continue reading Figure 3 , Figure 6 , wherein the vehicle body 2 includes a vehicle body upper end surface 22; the locking groove 21 includes at least one locking groove side surface 211; the convex buckle portion 4222 is configured to cooperate with the vehicle body upper end surface 22; the side extrusion portion 4223 is configured to cooperate with the locking groove side surface 211; the convex buckle portion 4222 cooperates with the vehicle body upper end surface 22 to limit the radial movement of the air spring; the side extrusion portion 4223 cooperates with the locking groove side surface 211 to limit the axial movement of the air spring.
[0039] Please continue reading Figure 3In some embodiments, the number of deformable blocks 422 is two, and they are respectively arranged on the left and right sides of the center column 421; under this arrangement, both sides of the center column 421 have structures that cooperate with the locking groove 21, and the forces on both sides are more balanced, which is beneficial to improving the reliability of the connection; and the number of deformable blocks 422 is two, which has a lower manufacturing cost than four or other numbers.
[0040] It is worth mentioning that the side extrusion portion 4223 extends from the lower end of the locking groove 21. When the body fastener 4 needs to be removed, the side extrusion portion 4223 only needs to be squeezed toward the deformation space 423 to withdraw the body fastener 4 from the locking groove 21.
