Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shock-absorbing pads for automobile piston air compressors, and in particular relates to a shock-absorbing structure and a piston air compressor and a vehicle using the same. Background Art
[0002] The working vibration generated by the piston air compressor will affect the installation foundation (such as vehicle cross beams, brackets, bases, etc.). Therefore, shock-absorbing pads are usually designed at the fixed connection position of the air compressor to isolate the vibration of the piston air compressor.
[0003] However, when the piston air compressor vibrates violently, the large displacement deformation of the shock absorber will exceed its normal elastic deformation range. Over time, it will cause the metal insert and rubber joint inside the shock absorber to tear, causing the shock absorber to fail. At the same time, the piston air compressor may collide with other parts around the vehicle chassis, causing the piston air compressor to experience problems such as bumps, abnormal noises, large vibrations and failure.

[0027] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0028] The utility model provides a shock-absorbing structure, which is used to solve the problem that the metal insert and the rubber joint inside the shock-absorbing pad will tear, causing the shock-absorbing pad to fail, and the shock-absorbing pad will produce large displacement deformation when the air compressor vibrates violently, causing the air compressor to collide with other parts around the vehicle chassis. The shock-absorbing structure is suitable for piston air compressors, and this type of piston air compressor is suitable for vehicles, such as automobiles.
[0029] like Figure 1 As shown, in one embodiment, a shock absorbing structure is provided, which includes no less than two shock absorbing units 30 (in one embodiment, the shock absorbing structure includes four shock absorbing units 30), a part of all the shock absorbing units 30 are arranged opposite to the remaining part (in one embodiment, two shock absorbing units 30 are located on the left side of the piston air compressor 10 and are arranged at intervals, and the other two shock absorbing units 30 are located on the right side of the piston air compressor 10 and are arranged at intervals), and each shock absorbing unit 30 includes: a hard insert 301, a first elastic layer 302, a second elastic layer 303 and a fixed base 304.
[0030] The rigid insert 301 includes a rigid main body portion 3011 extending in the vertical direction and a rigid accessory portion 3012 extending in the horizontal direction and located on both sides of the rigid main body portion 3011. In one embodiment, the rigid main body portion 3011 of the rigid insert is a cylindrical shape with a hollow interior and a threaded inner wall. The positioning pin 305 connects the rigid main body portion 3011 of the rigid insert to the mounting bracket 201 to determine the position of the shock absorbing unit 30 and prevent the top of the shock absorbing unit 30 from twisting during installation and removal. The rigid accessory portion 3012 of the rigid insert is a cylindrical shape with a threaded inner wall. The hard insert 301 is in the shape of a cap with an opening. The upper end of the hard main part 3011 passes through the opening of the hard accessory part 3012 and extends in the vertical direction. The lower end of the hard main part 3011 is located at the lower end of the opening of the hard accessory part 3012. The hard accessory part 3012 is fixed to the bottom of the hard main part 3011 by a bolt 306. In one embodiment, the hard insert 301 is made of a metal material, such as iron or copper. Of course, the hard insert 301 can also be an alloy material with a certain hardness, such as stainless steel. In one embodiment, the bolt 306 is a hexagon socket bolt.
[0031] The first elastic layer 302 is sleeved on the rigid main body part 3011 of the rigid insert; in one embodiment, the first elastic layer 302 is roughly in the shape of an inverted bowl and has a through opening at the top, and the outer peripheral wall of the first elastic layer 302 near the bottom end has a circumferentially arranged groove, and the outer side wall of the rigid main body part 3011 of the rigid insert is in sliding contact with the inner side wall of the top opening of the first elastic layer 302; in one embodiment, the first elastic layer 302 is made of rubber material, for example, vulcanized rubber;
[0032] The second elastic layer 303 is sleeved on the rigid attachment part 3012 of the rigid insert; in one embodiment, the second elastic layer 303 is annular and wrapped on the cap edge of the rigid attachment part 3012 of the rigid insert; in one embodiment, the second elastic layer 303 is made of rubber material, for example, vulcanized rubber; the second elastic layer 303 and the first elastic layer 302 have a first gap X in the vertical direction;
[0033] The fixed base 304 is arranged at the bottom of the first elastic layer 302, and the fixed base 304 is arranged at the periphery of the second elastic layer 303 and the hard insert 301; in one embodiment, the top of the fixed base 304 is a cap-shaped having an opening, and the top portion of the fixed base 304 close to the opening is clamped in the slot of the first elastic layer 302.
[0034] When the vehicle loaded with the piston air compressor is running smoothly, the shock absorbing structure is in a normal state, and the deformation displacement of the shock absorbing structure is mainly caused by the first elastic layer 302; when the shock absorbing structure is in a normal state, the second elastic layer 303 and the first elastic layer 302 have a first gap X in the vertical direction (in one embodiment, the first gap X is the distance formed by the top surface of the second elastic layer 303 and the bottom surface of the first elastic layer 302 in the vertical direction, and the gap value is greater than 0), and the first gap X is the deformation displacement distance of the shock absorbing structure in the vertical direction; the fixed base 304 and the second elastic layer 303 have a second gap Y in the horizontal direction (in one embodiment, the second gap Y is the distance formed by the outer side wall of the second elastic layer 303 in the horizontal direction and the inner side wall of the fixed base 304 in the horizontal direction, and the gap value is greater than 0), and the second gap Y is the deformation displacement distance of the shock absorbing structure in the horizontal direction; by reasonably controlling the first gap X and the second gap Y, the deformation displacement amount of the shock absorbing structure under severe vibration of the piston air compressor can be guaranteed, and the shock absorbing structure will not have tearing failure and air compressor collision problems.
[0035] When a vehicle loaded with a piston air compressor is slightly bumped during driving, the shock-absorbing structure is in a vertical stress state; when the shock-absorbing structure is in a vertical stress state (horizontal stress is almost negligible), the compression of the first elastic layer 302 increases, and the compression of the first elastic layer 302 is greater than the compression of the first elastic layer 302 when the shock-absorbing structure is in a normal state, so that the first elastic layer 302 and the second elastic layer 303 are in contact or extrusion state in the vertical direction, and the fixed base 304 and the second elastic layer 303 have a second gap Y in the horizontal direction.
[0036] When a vehicle loaded with a piston air compressor encounters a speed bump or bad road conditions during driving and the vehicle is severely bumped, the shock-absorbing structure is in a horizontal force state (the vertical force can be almost ignored); when the shock-absorbing structure is in a horizontal force state, the second elastic layer 303 and the first elastic layer 302 have a first gap X in the vertical direction, and the fixed base 304 and the second elastic layer 303 are in contact or extrusion state in the horizontal direction.
[0037] When a vehicle loaded with a piston air compressor encounters a speed bump and bad road conditions during driving and the vehicle is severely bumped, the shock-absorbing structure is in a state of being stressed both horizontally and vertically; when the shock-absorbing structure is in a state of being stressed both horizontally and vertically, the elastic deformation of the first elastic layer 302 exceeds its normal elastic deformation range, the second elastic layer 303 and the first elastic layer 302 are in contact or extrusion in the vertical direction, and the fixed base 304 and the second elastic layer 303 are in contact or extrusion in the horizontal direction, preventing the deformation and displacement of the shock-absorbing structure, thereby effectively avoiding tearing of the shock-absorbing structure caused by long-term large displacement deformation.
[0038] like Figure 2 As shown, in one embodiment, the shock absorbing structure further includes a mounting portion for connecting the shock absorbing structure in the above embodiment with the piston air compressor and the vehicle; in one embodiment, the mounting portion 20 includes a mounting bracket 201 and a mounting base 202 .
[0039] The mounting bracket 201 is fixed to the left and right sides of the piston air compressor by bolts. The top of the side plate of the mounting bracket 201 has a horizontal plate portion. A hole is left on the horizontal plate portion of the mounting bracket 201. The rod member 203 with a threaded rod wall is screwed into the screw hole of the hard main body part 3011 of the hard insert and fixed with a nut, so that the shock absorbing unit 30 is connected to the mounting bracket 201.
[0040] The mounting base 202 is a rectangular parallelepiped member with a groove in the middle of the top. The piston air compressor 10 is placed in the groove in the middle of the mounting base 202. The mounting base 202 is used to arrange the shock absorbing structure on the vehicle through bolts.
[0041] The utility model has a simple structure and improves the large-amplitude vibration generated by the piston air compressor by means of the first gap and the second gap arranged inside the shock-absorbing structure, thereby effectively avoiding the failure of the shock-absorbing pad due to long-term large displacement deformation and the problem of collision between the piston air compressor and other components.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present specification shall be included in the scope of protection of one or more embodiments of the present specification.
