The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the present application include all alternatives, modifications, and equivalents as may be included within the spirit and scope of the appended claims.
The shock absorbing strength adjusting device of the automobile shock absorber according to the embodiment of the present application is described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the damping strength adjusting device of the automobile damper according to the embodiment of the application comprises a damper body 1, wherein the damper body 1 comprises an oil cylinder 11, connecting buckles 12 and compression springs 13, the connecting buckles 12 are arranged at two ends of the oil cylinder 11, and two ends of the compression springs 13 are respectively connected with the two connecting buckles 12.
The oil cylinder 11 is connected with a damping strength adjusting mechanism 3 through a hydraulic pipe 2, the damping strength adjusting mechanism 3 comprises an adjusting cylinder body 33, a compression assembly 37 and a strength adjusting assembly 39, wherein a nozzle tip 31 is arranged at the top of the adjusting cylinder body 33, and the nozzle tip 31 is connected with the oil cylinder 11 through the hydraulic pipe 2.

Specifically, when the shock absorber body 1 is in use, the hydraulic oil 4 in the compression assembly 37 is connected with the cylinder 11 in the shock absorber body 1 through the hydraulic pipe 2, so that the pressure in the cylinder 11 is always equal to the pressure in the compression assembly 37.
Before the shock absorber body 1 is stressed, as shown in fig. 4, the tension spring 373 in the compression assembly 37 is in a reset and contracted state, then, as shown in fig. 5, when the shock absorber body 1 is subjected to external pressure, the hydraulic oil 4 in the oil cylinder 11 is extruded into the silica gel cylinder 372 by the compression of the oil cylinder 11, and the silica gel cylinder 372 expands to drive the tension spring 373 to stretch downwards (because the tension spring 373 is embedded in the middle of the inner wall and the outer wall of the silica gel cylinder 372, the silica gel cylinder 372 only stretches up and down).
When the shock absorber body 1 is subjected to external pressure reduction, the silica gel cylinder 372 drives the tension spring 373 to retract upwards, and hydraulic oil 4 in the silica gel cylinder 372 flows back into the oil cylinder 11.
When the damping strength of the damper body 1 needs to be improved, the compression rigidity of the cylinder 11 in the damper body 1 becomes harder, as shown in fig. 7, by controlling the oil guiding direction of the adjusting oil pump 35, the adjusting oil pump 35 sucks hydraulic oil 4 below the piston 38 and transfers the hydraulic oil 4 into the silica gel cylinder 372, the pressure of the hydraulic oil 4 in the silica gel cylinder 372 is increased, so that the hydraulic oil 4 in the cylinder 11 in the damper body 1 is more laborious to squeeze into the silica gel cylinder 372, the damping strength of the damper body 1 is improved, and the moving distance of the bottom of the silica gel cylinder 372 is the same as the downward moving distance of the piston 38 (compared with fig. 4), so that the expansion stroke of the silica gel cylinder 372 is unchanged, and the cylinder 11 does not lose the damping stroke.

Specifically, the top area of the piston 38 is equal to the area of the bottom of the silica gel cylinder 372, so that in the initial state of the silica gel cylinder 372, the top of the piston 38 is always equal to the bottom of the silica gel cylinder 372, the elastic deformation amount of the silica gel cylinder 372 and the tension spring 373 is controlled between reaching the piston 38, and the hard contact between the bottom of the silica gel cylinder 372 and the piston 38 is reduced.
In one embodiment of the application, as shown in fig. 2 and 3, a rebound adjusting assembly 5 is arranged inside a silica gel cylinder 372, the rebound adjusting assembly 5 comprises a porous rubber block 6, a guide pipe 53, an adjusting rod 52 and a one-way valve 311, wherein the porous rubber block 6 is arranged inside the silica gel cylinder 372, the guide pipe 53 is arranged inside the silica gel cylinder 372, the bottom of the adjusting rod 52 is arranged on the inner side of the adjusting rod 52 in a sliding manner, the top of the adjusting rod 52 is communicated with a nozzle 31, and the one-way valve 311 is arranged on the top of the silica gel cylinder 372.
The top of adjusting cylinder 33 rotatably is provided with adjusting nut 521, and adjusting lever 52 screw thread runs through adjusting nut 521, and adjusting lever 52's top is provided with the backward flow cover 51 that can reciprocate, and adjusting lever 52 passes through backward flow cover 51 and oil groove intercommunication, and backward flow hole 522 has been seted up to adjusting lever 52's bottom, and stand pipe 53 is hollow out construction, and check valve 311 is located between oil end and the 372 top oil end of guide groove 36 top.
Specifically, when the cylinder 11 compresses, as shown in fig. 4-5, since the porous rubber block 6 is arranged in the silica gel cylinder 372, oil of the cylinder 11 enters the upper side of the porous rubber block 6 through the one-way valve 311, and hydraulic oil 4 enters the bottom of the porous rubber block 6 through the porous structure for a certain time, so that the porous rubber block 6 plays a role in certain compression and rebound damping.
The oil at different depths of the porous rubber block 6 is regulated by the regulating rod 52 with the upper and lower reflux positions, so that the reflux speed is regulated (the deeper the regulating rod 52 is, the deeper the depth of the hydraulic oil 4 entering the porous rubber block 6 is, the slower the speed of oil reflux to the regulating rod 52 is, the slower the rebound of the silica gel cylinder 372 is, and the faster the reverse is), and the refluxed oil enters the oil nozzle 31 through the reflux sleeve 51, so that the rebound speed is regulated.
It should be noted that, the adjusting rod 52 adjusts the up and down position through the adjusting nut 521, and the guiding tube 53 is a hollow structure for supporting the porous rubber block 6 to prevent friction contact with the adjusting rod 52, and for guiding the adjusting rod 52 up and down.

It should be noted that, a certain gap needs to be reserved between the outer side wall of the silica gel cylinder 372 and the inner wall of the adjusting cylinder 33, so that friction between the silica gel cylinder 372 and the inner wall of the adjusting cylinder 33 in the up-down expansion process is prevented, and the shock absorber has the advantages that only elastic deformation and no friction occur in the up-down expansion process of the silica gel cylinder 372 due to rapid vibration in the high-speed running process of the shock absorber body 1, so that generated heat is extremely small, and fatigue resistance of the shock absorber is improved.
In one embodiment of the present application, as shown in fig. 2, the top end of the adjusting cylinder 33 is provided with an upper sealing cover 32, and the bottom end of the adjusting cylinder 33 is provided with a lower sealing cover 34, so that the disassembly and maintenance of the shock absorption intensity adjusting mechanism 3 at a later stage are facilitated.
For clarity of description of the above embodiment, as shown in fig. 4 to 7, the shock-absorbing-strength adjusting device for an automobile shock absorber of the present application is actually used:
first, the hydraulic oil 4 in the compression assembly 37 is connected to the cylinder 11 in the damper body 1 through the hydraulic pipe 2, so that the pressure in the cylinder 11 is always equal to the pressure in the compression assembly 37.
Before the shock absorber body 1 is stressed, as shown in fig. 4, the tension spring 373 in the compression assembly 37 is in a reset and contracted state, as shown in fig. 5, when the shock absorber body 1 receives external pressure, hydraulic oil 4 in the oil cylinder 11 is extruded into the silica gel cylinder 372 through the one-way valve 311, and the silica gel cylinder 372 expands to drive the tension spring 373 to stretch downwards (because the tension spring 373 is embedded in the middle of the inner wall and the outer wall of the silica gel cylinder 372, the silica gel cylinder 372 only stretches up and down). When the shock absorber body 1 is subjected to external pressure reduction, hydraulic oil 4 in the silica gel cylinder 372 enters the drainage tube through the bottom of the base plate 371, the hydraulic oil 4 flows back to the oil guide groove 36 and finally flows back into the oil cylinder 11, and the silica gel cylinder 372 drives the tension spring 373 to retract upwards.
When the shock absorption strength of the shock absorber body 1 needs to be improved, the shock absorber body 1 becomes harder, as shown in fig. 7, by controlling the oil guiding direction of the oil pump 35, the oil pump 35 is adjusted to absorb the hydraulic oil 4 below the piston 38 and transfer the hydraulic oil 4 into the silica gel cylinder 372, the pressure of the hydraulic oil 4 in the silica gel cylinder 372 is increased, so that the hydraulic oil 4 in the oil cylinder 11 in the shock absorber body 1 is extruded into the silica gel cylinder 372 more difficultly, the shock absorption strength of the shock absorber body 1 is improved, and the moving distance of the bottom of the silica gel cylinder 372 is the same as the downward moving distance of the piston 38 (compared with fig. 4), so that the telescopic stroke of the silica gel cylinder 372 is unchanged, and the oil cylinder 11 does not lose the shock absorption stroke, and the bottom area of the silica gel cylinder 372 is equal to the top area of the piston 38.
In addition, the adjusting cylinder 33 is reserved with the breathing air hole 331, so that the air in the adjusting cylinder 33 is balanced in time in the up-down expansion process of the silica gel cylinder 372, the high-speed movement of the silica gel cylinder 372 is prevented from compressing the air in the adjusting cylinder 33, and the temperature rise in the adjusting cylinder 33 is prevented.
The oil is injected through the oil injection nozzle 341, and the up-and-down moving stroke of the silica gel cylinder 372 can be regulated through the oil injection quantity, so that the telescopic stroke of the oil cylinder 11 is regulated.
Certain gaps are reserved between the outer side wall of the silica gel cylinder 372 and the inner wall of the adjusting cylinder 33, friction between the silica gel cylinder 372 and the inner wall of the adjusting cylinder 33 in the vertical stretching process is prevented, and the shock absorber has the advantages that only elastic deformation and no friction are generated in the vertical stretching process of the silica gel cylinder 372 in consideration of rapid vibration in the high-speed running process of the shock absorber body 1, so that generated heat is extremely small, and fatigue resistance of the shock absorber is improved.
It should be noted that, both ends of the tension spring 373 are respectively connected with the top plate 374 and the bottom plate 371, wherein the top plate 374 is fixed at the top of the inner wall of the adjusting cylinder 33, and the top plate 374 and the bottom plate 371 are used for supporting the upper and lower ends of the silica gel cylinder 372, so that the silica gel cylinder 372 is well supported to extend and retract up and down.
In addition, when in use, the elastic deformation quantity of the silica gel cylinder 372 and the tension spring 373 is controlled between the piston 38, so that the hard contact between the bottom of the silica gel cylinder 372 and the piston 38 is reduced, commonly called priming.
Even when the bottom of the silica gel cylinder 372 is in hard contact with the piston 38, as shown in fig. 6, the silica gel cylinder 372 is outwards and circumferentially tightened by the tension spring 373, but the silica gel cylinder 372 ash between small gaps generated by the tension spring 373 expands, so that the hydraulic oil 4 in the oil cylinder 11 can further flow and buffer, and the protection effect on the oil cylinder 11 is achieved.
As shown in fig. 4-5, when the rebound speed needs to be adjusted, as the porous rubber block 6 is arranged in the silica gel cylinder 372, oil at the oil nozzle 31 enters the upper side of the porous rubber block 6 through the one-way valve 311, and hydraulic oil 4 enters the bottom of the porous rubber block 6 through the porous structure for a certain time, so that the porous rubber block 6 plays a role in certain compression and rebound damping.
When the oil cylinder 11 compresses and drives the silica gel cylinder 372 to compress, the oil at different depths of the porous rubber block 6 is regulated by the regulating rod 52 with the upper and lower reflux positions, so that the reflux speed is regulated, and the refluxed oil enters the oil nozzle 31 through the reflux sleeve 51, so that the rebound speed is regulated.
In summary, according to the damping strength adjusting device of the automobile damper, the compression strength of the oil cylinder is adjusted through adjusting the initial compression strength of the silica gel cylinder, and then the compression strength of the damper is adjusted.
