Referring to fig. 1, the present embodiment provides an automobile including a chassis, a body, and a shock absorber 100. Shock absorber 100 is connected between the chassis and the vehicle body to achieve shock filtering.
Referring to fig. 1, 2 and 3, in the present embodiment, the shock absorber 100 includes a base 110, an oil storage cylinder 131, a push rod 133, a piston 135, an air bag cylinder 150 and an air bag assembly 170. The base 110 has a first mount 113 and a second mount 115, and an oil delivery flow passage 117 communicating the first mount 113 and the second mount 115. The oil reservoir 131 is mounted to the first mounting seat 113, and the piston 135 is mounted to the push rod 133 and is movably mounted in the oil reservoir 131 to divide the oil reservoir 131 into an upper cavity and a lower cavity. The airbag module 170 is movably mounted to the airbag housing 150 by mounting the airbag housing 150 to the second mounting bracket 115 such that the airbag housing 150 is in communication with the oil delivery flow passage 117. After the shock absorber 100 is compressed, the oil of the oil storage cylinder 131 is pushed by the piston 135, so that the oil flows into the air bag cylinder 150 from the oil flow passage 117, and the damping oil flowing into the air bag cylinder 150 can press the air bag deformation of the air bag assembly 170 and push the air bag assembly 170 to move.
The present embodiment is configured to move the balloon assembly 170 by removably mounting the balloon assembly 170 within the balloon barrel 150 such that the damping oil can compress the balloon deformation of the balloon assembly 170 and push the balloon assembly 170 into movement as the damping oil enters the balloon barrel 150. Therefore, the vehicle corresponds to different damping curves under different road conditions. For example, the deformation of the extrusion air bag can correspond to the shock absorption of acceleration, deceleration and other conditions in the normal form process of the automobile, and the movement of the pushing air bag can correspond to the shock absorption of the automobile subjected to external large impact.
In the present embodiment, the airbag module 170 includes a slide seat 171 and an airbag 173 mounted to the slide seat 171, with an air storage space 175 formed between the slide seat 171 and the airbag 173. The slide seat 171 is movably installed in the airbag case 150, and the damping oil flowing into the airbag case 150 can compress the airbag 173 to deform.
Providing the airbag module 170 as a sliding seat 171 facilitates movement of the entire airbag module 170 relative to the existing airbag cartridge 150.
Referring to fig. 1, 2 and 3, in the present embodiment, the air bag tube 150 includes a tube body 151 and a rear cover 153. The barrel 151 is mounted on the second mounting base 115, and the barrel 151 is provided with a stop collar 155. The rear cover 153 is mounted on a side of the barrel 151 remote from the second mount 115. The sliding seat 171 is movably disposed between the rear cover seat 153 and the stop collar 155.
The present embodiment provides a stop collar 155 to allow the airbag module 170 to slide between preset positions. And most importantly, allows for independent deformation and movement of the airbag module 170.
Referring to fig. 1, 2 and 3, in the present embodiment, the shock absorber 100 further includes a sealing ring 179, and a sealing ring groove 177 is disposed on a side wall of the sliding seat 171. The seal ring 179 is disposed in the seal ring groove 177, and the seal ring 179 can seal between the side wall of the sliding seat 171 and the inner wall of the barrel 151, so that a sealed space 181 is formed between the sliding seat 171 and the rear cover 153.
In this embodiment, the sealing ring 179 is disposed, so that the airtight space 181 is formed between the sliding seat 171 and the rear cover seat 153, so that two relatively independent cavities can be formed, and better damping is achieved.
In this embodiment, the gas storage space 175 is provided with a gas of a first preset pressure, and the enclosed space 181 stores a gas or liquid of a second preset pressure. The first preset pressure is less than the second preset pressure.
The first preset pressure is smaller than the second preset pressure, so that when the chassis of the vehicle is impacted by small external force, the air bag is extruded to deform, and the vibration and the energy are absorbed. When a large impact force is received, the air bag deformation and the movement of the air bag assembly 170 can jointly act on the air or liquid in the compressed closed space 181 to absorb shock and energy, so that a better shock and energy absorption effect is realized.
Referring to fig. 1, 2 and 3, in the present embodiment, the sliding seat 171 is provided with a first inflation/deflation assembly 183, the first inflation/deflation assembly 183 can inflate/deflate the air storage space 175, the rear cover seat 153 is provided with a second inflation/deflation assembly 157, and the second inflation/deflation assembly 157 can inflate/deflate the enclosed space 181.
The first inflation and deflation assembly 183 and the second inflation and deflation assembly 157 are arranged to respectively inflate and deflate the gas storage space 175 in the air bag and the airtight space 181 of the cylinder, so that the training is convenient, and different vehicle types can be matched.
Referring to fig. 4, in other embodiments of the present application, the shock absorber 100 further includes a spring 190, and the spring 190 is disposed between the rear cover 153 and the sliding seat 171.
It should be noted that the spring 190 and the air inflation of the enclosed space 181 may exist at the same time, or only one may be provided. When only the spring 190 is provided, the seal between the sliding seat 171 and the cylinder wall may not be used.
Referring to fig. 1, 2 and 3, in the present embodiment, an oil hole is provided on the piston 135, and when the push rod 133 drives the piston 135 to move, damping oil can flow between the upper cavity and the lower cavity through the oil hole.
In this embodiment, shock absorber 100 further includes a spring seat 139 and a shock spring 137. The spring seat 139 is connected to the push rod 133, and the spring 190 is sleeved on the oil reservoir 131, and one end of the spring is abutted against the spring seat 139, and the other end is abutted against the base 110.
Typically, one of the spring seat 139 and the base 110 is mounted to the vehicle body, and the other is connected to the chassis.
In summary, the working principles and beneficial effects of the shock absorber 100 and the vehicle provided by the embodiments of the present utility model include:
The present embodiment is configured to move the balloon assembly 170 by removably mounting the balloon assembly 170 within the balloon barrel 150 such that the damping oil can compress the balloon deformation of the balloon assembly 170 and push the balloon assembly 170 into movement as the damping oil enters the balloon barrel 150. Therefore, the vehicle corresponds to different damping curves under different road conditions. For example, the deformation of the extrusion air bag can correspond to the shock absorption of acceleration, deceleration and other conditions in the normal form process of the automobile, and the movement of the pushing air bag can correspond to the shock absorption of the automobile subjected to external large impact.
The present utility model is not limited to the above embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
