DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example

[0026] See also Figures 1 to 5 , is an embodiment of the present invention, which provides a technical solution: an intelligent air suspension bracket assembly, comprising

[0027] An axle seat 7 fixed on the axle, a bracket seat 2 fixed on the bottom of the frame, two bracket plates 3 fixed on the bottom of the bracket seat 2, and a guide arm 1 fixed on the bottom of the airbag 8, a fixing seat 71 is provided between the guide arm 1 and the axle seat 7, and the left end of the guide arm 1 is hinged between the two bracket plates 3;

[0028] and a cylindrical shaft block 4, the surface of the bracket plate 3 is provided with a shaft hole 31 for inserting the cylindrical shaft block 4, the left end surface of the guide arm 1 is provided with a circular through hole corresponding to the cylindrical shaft block 4, the cylindrical shaft block 4 passes through the left end of the guide arm 1 through the circular through hole, and the two ends of the cylindrical shaft block 4 are respectively inserted into the shaft holes 31 on the surfaces of the two bracket plates 3, the cylindrical shaft block 4 after passing through can realize the hinge between the guide arm 1 and the bracket plate 3, and the two end surfaces of the cylindrical shaft block 4 are provided with an annular groove 41;

[0029] And a limiting mechanism, the limiting mechanism includes an inner slide groove 91 opened inside the bracket seat 2, a spring 92 and an inner slide block 93 installed in the inner slide groove 91, and two limiting clamping rods 94 welded and fixed at the bottom of the inner slide block 93. The bottom end of the limiting clamping rod 94 passes through the shaft hole 31, and the bottom end of the limiting clamping rod 94 is clamped in the annular clamping groove 41 to achieve stable limiting of the cylindrical shaft block 4. The limiting mechanism also includes a pressing hole 96 opened at the center of the bottom of the bracket seat 2, and the inner slide block 93 A pressing block 95 is fixed at the bottom center, and the pressing block 95 is located in the pressing hole 96. The pressing block 95 can be pushed up later, so that the inner sliding block 93 moves up with the limiting clamping rod 94, thereby releasing the limiting of the cylindrical shaft block 4, realizing the rapid withdrawal of the cylindrical shaft block 4, and then realizing the rapid disassembly and assembly between the guide arm 1 and the bracket plate 3, which is convenient for subsequent inspection and maintenance. Compared with the traditional bolt limiting method, the later disassembly and assembly is simpler and faster, thereby improving the overall convenience of later maintenance.

[0030] There are two springs 92 in the inner slide groove 91, and two cylindrical grooves are provided on the top surface of the inner slide block 93 for inserting the bottom ends of the springs 92, so that the two springs 92 can be limited to prevent deviation.

[0031] Among them, a sealing gasket 21 is also installed at the bottom center of the bracket seat 2, and the sealing gasket 21 covers the pressing hole 96 to prevent foreign objects from accidentally entering. An integrated U-shaped plug block 22 is provided on the top surface of the sealing gasket 21, and the U-shaped plug block 22 is inserted into the pressing hole 96. Both side surfaces of the U-shaped plug block 22 are provided with integrated side clamping blocks 23, both of which are made of rubber material and will undergo elastic deformation when squeezed. Side clamping grooves 24 corresponding to the side clamping blocks 23 are provided on the inner walls on both sides of the pressing hole 96, and the side clamping blocks 23 are inserted into the side clamping grooves 24 to achieve stable limiting of the U-shaped plug block 22 and the sealing gasket 21, thereby ensuring the installation stability of the sealing gasket 21. When it is necessary to press the pressing block 95 in the later stage, the sealing gasket 21 only needs to be pulled down hard to pull out the U-shaped plug block 22.

[0032] It also includes a monitoring system, which includes

[0033] A main control module, a data transmission module, a monitoring module, a reminder module, a power module, a data recording module and a data comparison module. The monitoring module includes a displacement sensor 6 installed on the surface of the bracket plate 3. The model of the displacement sensor 6 is BTL5-S175B-M1800-P-S32, which can record the displacement distance of the bracket plate 3 each time. The reminder module includes a signal sending module connected to the vehicle system, which can send a reminder signal to the vehicle system. When the monitoring system is actually running, the displacement sensor 6 can sense the displacement distance of the bracket plate 3 each time it is lifted and lowered, and send it to the main control module through the data transmission module, and the main control module records the data through the data recording module, and also compares the displacement data of each time through the data comparison module. If the current displacement distance is less than the previously recorded displacement data, it is determined that the load-bearing airbag 8 may be damaged. At this time, the main control module will start the reminder module to send an abnormal signal to the vehicle system to remind the driver that the vehicle's load-bearing airbag 8 may be abnormal and needs to be repaired immediately.

[0034] Among them, the power module is used to supply power to the monitoring system.

[0035] An air suspension system including an intelligent air suspension bracket assembly also includes a load-bearing airbag 8 installed at the bottom of a vehicle frame and connected to the right end of a guide arm 1, and a shock absorber 5 connected between the guide arm 1 and the rear surface of a bracket plate 3.
