Air Suspension with Exhaust Structure

Technical Field

The utility model relates to the technical field of air suspension systems, and in particular to an air suspension with an exhaust structure.

Background Art

Air suspension is an advanced product widely used in the automotive industries of developed countries. By adjusting the chassis ground clearance through the air suspension system, vehicle stability at high speeds and passability under complex road conditions can be improved, thereby enhancing driving quality.

However, existing air suspension systems lack:

an effective structure for deflating the inflatable airbag,

an effective dustproof mechanism for the exhaust outlet to prevent dust from entering and causing cleaning difficulties,

and an effective mechanism for removing dust accumulated on the dustproof mesh over time, which may otherwise block the mesh and hinder rapid air discharge from the airbag.

Therefore, it is necessary to provide an air suspension with an exhaust structure to solve the above technical problems.

Summary of the Utility Model

The utility model provides an air suspension with an exhaust structure, solving the problems that conventional air suspension systems:

cannot effectively release air from the inflatable airbag,

lack effective dust prevention at the exhaust outlet,

and cannot effectively remove accumulated dust from the dustproof mesh, resulting in blockage and poor exhaust efficiency.

To solve the above technical problems, the utility model provides an air suspension with an exhaust structure comprising:

an inflatable airbag,

an inflation pipe fixedly connected to the outside of the inflatable airbag,

an air inlet valve installed on the inflation pipe,

an air pump fixedly connected to one side of the inflation pipe,

a connector fixedly connected to the outer side of the inflation pipe,

and an exhaust head fixedly mounted on the connector.

An annular sliding groove is formed inside the connector, and an annular sliding block is slidably connected inside the annular sliding groove. A movable plate is fixedly mounted outside the annular sliding block. The outer side of the movable plate is engaged with a gear through a toothed strip structure. A micro motor is installed at the bottom end of the gear through a connecting shaft.

Exhaust ports are formed inside both the exhaust head and the movable plate. A dustproof mechanism is arranged inside the exhaust ports of the movable plate, and a cleaning mechanism is installed outside the gear.

Preferred Embodiments

Preferably, an elastic sealing gasket is fixedly connected to the top end of the exhaust head, and exhaust holes corresponding to the exhaust ports on the exhaust head are formed on the elastic sealing gasket. The elastic sealing gasket is fitted closely against the movable plate.

Preferably, the dustproof mechanism includes a dustproof mesh, and connecting blocks are uniformly fixed around the top end of the dustproof mesh. Silicone balls are fixedly connected to the bottom ends of the connecting blocks, and clamping grooves are movably connected between the silicone balls and the movable plate.

Preferably, the dustproof mesh forms a clamping structure with the movable plate through the silicone balls and the clamping grooves, and the movable plate forms a rotating structure with the connector through the annular sliding block and the annular sliding groove.

Preferably, the cleaning mechanism includes a fixing column fixedly mounted outside the gear. A sleeve ring is movably sleeved on the fixing column, and a brush rod is fixedly connected to the outer side of the sleeve ring. A hand-tightening bolt is threaded onto the outer side of the fixing column.

Preferably, a soft brush is arranged on the side of the brush rod that contacts the movable plate, and the brush rod forms a detachable structure with the gear through the sleeve ring, the fixing column, and the hand-tightening bolt.

Beneficial Effects

Compared with the related art, the air suspension with an exhaust structure provided by the utility model has the following beneficial effects:

1. Efficient Exhaust Function

When the inflatable airbag needs to be deflated, the external power supply of the micro motor is activated, causing the gear to rotate. The gear drives the engaged movable plate to rotate along the annular sliding groove of the connector through the annular sliding block.

When the exhaust ports on the movable plate align with the exhaust ports on the exhaust head, the air inside the inflatable airbag is squeezed out under pressure, thereby completing the exhaust operation and lowering the overall support structure connected to the shock absorber.

After a certain degree of exhaust is completed, the micro motor rotates again to separate the exhaust ports of the movable plate from those of the exhaust head. An elastic sealing gasket is provided on the top end of the exhaust head, effectively preventing air leakage after separation and providing excellent sealing performance.

2. Effective Dustproof Function

Through the action of the dustproof mechanism, when the four exhaust ports on the movable plate require dust protection, the dustproof mesh can be inserted into the exhaust ports.

The silicone balls connected to the connecting blocks around the dustproof mesh engage with the clamping grooves formed on the movable plate, thereby securely fixing the dustproof mesh in position.

This allows the dustproof mesh to effectively prevent dust from entering the exhaust ports and prevents dirt from falling into the exhaust ports of the exhaust head during rotation of the movable plate.

3. Automatic Cleaning Function

During vehicle operation, dust may accumulate on the dustproof mesh over time, causing blockage and reducing air permeability.

When the gear rotates, the brush rod rotates together with the gear. The soft brush arranged on the side contacting the movable plate moves across the surface of the dustproof mesh installed at the exhaust ports, thereby cleaning accumulated dust from the surface.

This prevents deterioration of the ventilation performance of the dustproof mesh and ensures smooth exhaust operation of the inflatable airbag. In addition, the brush rod can be conveniently replaced by loosening the hand-tightening bolt.

Detailed Description

The utility model is further described below in conjunction with the accompanying drawings and embodiments.

Referring to Figures 1 to 6, the air suspension with exhaust structure includes the inflatable airbag 1, inflation pipe 2, air inlet valve 3, air pump 4, connector 5, exhaust head 6, exhaust port 7, annular sliding groove 8, annular sliding block 9, movable plate 10, gear 11, micro motor 12, dustproof mechanism 13, dustproof mesh 1301, connecting block 1302, silicone ball 1303, clamping groove 1304, cleaning mechanism 14, fixing column 1401, sleeve ring 1402, brush rod 1403, and hand-tightening bolt 1404.

The inflatable airbag 1 is inflated through the inflation pipe 2 by the air pump 4, allowing the support structure to rise.

When lowering of the support structure is required, the micro motor 12 is activated, causing the gear 11 to rotate. The movable plate 10 rotates through the annular sliding block 9 along the annular sliding groove 8 of the connector 5.

When the exhaust ports 7 of the movable plate align with those of the exhaust head 6, air inside the inflatable airbag 1 is discharged, thereby completing the exhaust process and lowering the support structure.

Meanwhile, the brush rod 1403 rotates together with the gear 11, allowing the soft brush to clean the surface of the dustproof mesh 1301 continuously, preventing dust accumulation and maintaining good air permeability.
