Technical Field

[0001] The utility model relates to the technical field of air suspension support crossbeams, in particular to an air suspension support crossbeam assembly for a new energy passenger vehicle. Background Art

[0002] New energy passenger vehicles usually refer to new energy sedans, which have the characteristics of energy saving and environmental protection. The air suspension support beam assembly is an important part of the air suspension system in new energy vehicles, which is used to support and connect other components of the air suspension. The existing air suspension support beam still has certain defects when in use.

[0003] In the prior art, air suspension support beams are usually used to support and transmit vehicle loads and vibrations. When driving on rough roads, the air suspension can raise the chassis to increase passability; when speeding up is required, the chassis can be lowered to achieve better grip. Since a portion of the outer side of the air shock absorber of the air suspension is made of rubber and the rubber sleeve is directly exposed to the outside world, the rubber sleeve will age faster when used for a long time under harsh conditions such as high temperature and high humidity, thereby affecting the normal use of the air shock absorber. Utility Model Content

[0004] The purpose of the utility model is to provide an air suspension support beam assembly for a new energy passenger vehicle, so as to solve the problem that the rubber sleeve on the air suspension support beam in the current market is easily damaged as mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new energy passenger car air suspension support beam assembly, comprising: an axle body, a connecting arm, an air shock absorber body and a corrugated rubber sleeve, connecting arms are installed on both sides of the axle body, the air shock absorber body is installed on the top of the connecting arm, the outer side of the air shock absorber body is installed with a corrugated rubber sleeve, a connecting block is welded to the outer side of the air shock absorber body, a reinforcement rod is welded to the outer side of the connecting block, a threaded limiting sleeve is threadedly connected to the top of the reinforcement rod, a telescopic protective hose is arranged on the outer side of the corrugated rubber sleeve, the telescopic protective hose is connected to a mounting block near the outer side of the connecting block, a threaded column is connected to the bottom end of the mounting block, a threaded column is threadedly connected to the outer side of the threaded column, a nut is threadedly connected to the outer side of the threaded column, a connecting ring is connected to the top of the telescopic protective hose, a sealing ring is installed inside the connecting ring, and a slider is connected to the connecting ring near the outer side of the reinforcement rod.

[0006] Preferably, a slot hole matching the size of the reinforcement rod is formed through the interior of the sliding block, and a sliding structure is formed between the sliding block and the reinforcement rod.

[0007] Preferably, the inner wall diameter of the connecting ring matches the outer diameter of the air shock absorber body, and a plug-in groove is provided through the interior of the connecting block.

[0008] Preferably, a fixing block is welded on the top of the axle body, and a receiving groove is formed on the top of the fixing block.

[0009] Preferably, the fixing block is connected to a spring near the interior of the receiving groove, and one end of the spring is connected to an extrusion block.

[0010] Preferably, a rubber plug is inserted into the top of the fixing block, and two groups of the fixing blocks are symmetrically arranged about the center of the axle body.

[0011] Compared with the prior art, the beneficial effect of the utility model is as follows: in the new energy passenger car air suspension supporting beam assembly, when the bottom of the mounting block moves the surface of the connecting block, the end of the threaded column can penetrate the connecting block, and at this time the nut can be sleeved on the outside of the threaded column and the nut can be tightened, and the wiring harness can be simply and conveniently fixed by the extrusion block and the rubber plug, and when the wiring harness is removed, the wiring harness can be pulled upward to be taken out from the inside of the fixing block, and the wiring harness can be quickly fixed and removed in this simple and convenient manner, thereby improving the convenience of fixing the wiring harness to the axle body.

[0012] 1. When the corrugated rubber sleeve on the air shock absorber body is used under harsh conditions such as high temperature and high humidity, its aging speed will be accelerated, thereby affecting the service life of the corrugated rubber sleeve. When the bottom of the mounting block moves the surface of the connecting block, the end of the threaded column can penetrate the connecting block. At this time, the nut can be sleeved on the outside of the threaded column and the nut can be tightened so that the top of the nut can move to the bottom of the connecting block. The sealing ring can be tightly sleeved on the outside of the air shock absorber body. When the sealing ring is squeezed and deformed by the air shock absorber body, the connecting ring can be fixed on the outside of the air shock absorber body. When the air shock absorber body is lifted or compressed during use, the corrugated rubber sleeve will be stretched or squeezed, and the connecting ring can be driven to move. When the connecting ring moves, the telescopic protective hose can be stretched or squeezed, so that during the use of the air shock absorber body, the telescopic protective hose can protect the outside of the corrugated rubber sleeve, making it difficult for the corrugated rubber sleeve to be used under harsh conditions such as high temperature and high humidity, and accelerate its aging speed, thereby extending the service life of the corrugated rubber sleeve.

[0013] 2. Cable ties are usually used to fix the wiring harness on the axle body. This fixing method is relatively cumbersome and inconvenient to disassemble. When the wiring harness moves to the inside of the storage slot, the inclined surfaces of the two groups of extrusion blocks can be squeezed so that the two groups of extrusion blocks can move in opposite directions. When the extrusion blocks move, the springs can be compressed. When the wiring harness moves between the two groups of extrusion blocks, the two groups of extrusion blocks can be reset by the springs. When the extrusion blocks are reset, the wiring harness can be squeezed and fixed. At the same time, the rubber plug is inserted into the storage slot. The wiring harness can be simply and conveniently fixed by the extrusion blocks and the rubber plug. At the same time, when removing the wiring harness, the wiring harness can be pulled upward to take it out from the fixing block. This simple and convenient method can quickly fix and remove the wiring harness, thereby improving the convenience of fixing the wiring harness on the axle body. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In specific implementation, when the corrugated rubber sleeve 4 on the air shock absorber body 3 is used under adverse conditions such as high temperature and high humidity, its aging speed will be accelerated, thereby affecting the service life of the corrugated rubber sleeve 4. For this reason, the telescopic protective hose 8 and the connecting ring 12 can be sleeved on the outside of the air shock absorber body 3, so that the end of the reinforcement rod 6 can pass through the slider 14. When the bottom of the mounting block 9 moves the surface of the connecting block 5, the end of the threaded column 10 can pass through the connecting block 5. At this time, the nut 11 can be sleeved on the outside of the threaded column 10, and the nut 11 can be tightened so that the top of the nut 11 can move to the bottom of the connecting block 5, thereby The mounting block 9 is fixed on the connecting block 5, and the sealing ring 13 can be tightly sleeved on the outer side of the air shock absorber body 3. The sealing ring 13 can improve the sealing between the connecting ring 12 and the air shock absorber body 3.

When the extrusion blocks 18 move, the spring 17 can be compressed. When the wiring harness moves between the two groups of extrusion blocks 18, the two groups of extrusion blocks 18 can be reset by the spring 17. When the extrusion blocks 18 are reset, the wiring harness can be squeezed and fixed, and the rubber plug 19 can be inserted into the storage groove 16 at the same time.

[0024] See also Figure 1 and Figure 3 It can be seen that the wire harness can be simply and conveniently fixed by the extrusion block 18 and the rubber plug 19. When removing the wire harness, the wire harness can be pulled upward to be taken out from the fixing block 15. Through this simple and convenient method, the wire harness can be quickly fixed and removed, thereby improving the convenience of fixing the wire harness on the axle body 1.

[0025] In summary, when using the air suspension support beam assembly of the new energy passenger car, the air suspension support beam is an important component of the air suspension system.
