[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts shall fall within the scope of protection of this application.

[0033] As Figures 1-5 shown, this embodiment provides an air suspension system with a dynamic power generation function, including:

[0034] A suspension main body 100, with at least one mounting portion provided on each side of the suspension main body 100.

[0035] An airbag shock absorption assembly 200, where the airbag shock absorption assembly 200 includes an airbag shock absorber and a sleeve 41, an electromagnetic coil 42, a support rod 43, and a permanent magnet 44 provided in the airbag shock absorber. One end of the sleeve 41 is a closed end and is connected to the airbag shock absorber. An installation socket is provided at the other end of the sleeve 41. The electromagnetic coil 42 is located inside the sleeve 41. The permanent magnet 44 is provided on the support rod 43. The support rod 43 is inserted into the sleeve 41. One end of the support rod 43 extends outside the sleeve 41 and is connected to the airbag shock absorber. The permanent magnet 44 is located inside the sleeve 41. The electromagnetic coil 42 is located outside the permanent magnet 44. The sliding direction of the permanent magnet 44 is the same as the shock absorption direction of the airbag shock absorber;

[0036] Among them, the airbag shock absorber is provided on the corresponding side mounting portion.

[0037] Specifically, during the use of the air suspension system with a dynamic power generation function, on the one hand, the suspension main body 100 is installed at the bottom of the vehicle body of the car, and on the other hand, the axle is also installed on the suspension main body 100. At the same time, the airbag shock absorber is connected to the vehicle body of the car.

[0038] During the driving of the car, due to road bumps, the load-bearing airbag 2 frequently expands and contracts, causing relative movement between the upper cover 1 and the base 3. In order to improve the shock absorption performance of the airbag shock absorber and, at the same time, make full use of the bump vibration to generate electricity. A sleeve 41, an electromagnetic coil 42, a support rod 43, and a permanent magnet 44 are provided in the airbag shock absorber. The sleeve 41, the electromagnetic coil 42, the support rod 43, and the permanent magnet 44 form a linear generator 4 in the airbag shock absorber. The reciprocating sliding direction of the permanent magnet 44 in the electromagnetic coil 42 will be basically the same as the expansion and contraction direction of the load-bearing airbag 2.

[0039] During actual use, when the vehicle is driving on an undulating road, the telescopic movement of the airbag shock absorber will drive the permanent magnet 44 to reciprocate in the electromagnetic coil 42. During the movement of the permanent magnet 44, a resistance will be generated between the permanent magnet 44 and the electromagnetic coil 42 to play an auxiliary shock-absorbing role.

[0040] By arranging the sleeve 41, the electromagnetic coil 42, the support rod 43 and the permanent magnet 44 in the airbag shock absorber, during the telescopic process of the airbag shock absorber, the support rod 43 will drive the permanent magnet 44 to reciprocate in the electromagnetic coil 42. On the one hand, the interaction between the permanent magnet 44 and the electromagnetic coil 42 generates resistance to assist the airbag shock absorber in playing a shock-absorbing role, thereby improving the shock-absorbing effect. On the other hand, the relative movement of the permanent magnet 44 with respect to the electromagnetic coil 42 can also generate electricity to enrich the functionality of the suspension. Moreover, since components such as the sleeve 41, the electromagnetic coil 42, the support rod 43 and the permanent magnet 44 are integrally installed in the airbag shock absorber, the overall structure is more compact.

[0041] For the performance entity of the suspension main body, a suspension structure in conventional technology can be adopted.

[0042] For example, as Figure 1 shown, the suspension main body 100 includes two guide arms 101 and a connecting frame 102. The two guide arms 101 are arranged side by side, and the connecting frame 102 is fixedly connected between the two guide arms 101; airbag shock absorber assemblies 200 are respectively arranged at both ends of the connecting frame 102, that is, two airbag shock absorber assemblies 200 are configured on the suspension main body 100. Among them, the airbag shock absorber assemblies 200 are respectively arranged at both ends of the connecting frame 102, and the two airbag shock absorber assemblies 200 on both sides can better play a shock-absorbing role for the vehicle body.

[0043] As Figure 6 shown in the structure of the suspension main body 100, four airbag shock absorber assemblies 200 can be configured.

[0044] As Figure 7 shown in the structure of the suspension main body 100, eight airbag shock absorber assemblies 200 can be configured.

[0045] As Figure 8 shown in the structure of the suspension main body 100, two airbag shock absorber assemblies 200 can be configured.

[0046] Among them, Figure 1 、 Figures 6-8 the structures of the suspension main body 100 are conventional suspension structures, which will not be limited and elaborated here. The following will take the structure of the suspension main body 100 in Figure 1 as an example for description.

[0047] Further, the airbag shock absorption assembly 200 further includes a rectifier 201 and a storage battery 202. The electromagnetic coil 42 is connected to the rectifier 201, and the rectifier 201 is connected to the storage battery 202.

[0048] Specifically, when used in an automobile, in order to recover and store the electric energy generated by vibration, a storage battery 202 can also be provided to store electric energy. The current output by the electromagnetic coil 42 is rectified by the rectifier 201 and then used to charge the storage battery 202 to achieve the storage of electric energy.

[0049] Further, the airbag shock absorber includes an upper cover 1, a load-bearing airbag 2, and a base 3. The load-bearing airbag 2 is arranged between the upper cover 1 and the base 3; the base 3 is fixedly installed on the connecting frame 102, the upper end of the support rod 43 is connected to the upper cover 1, and the closed end of the sleeve 41 is connected to the base 3.

[0050] Specifically, in addition, a wire passing hole is provided on the upper cover 1 or the base 3, and the power transmission cable of the linear generator 4 is hermetically inserted into the wire passing hole and extends to the outside of the air suspension system with dynamic power generation function.

[0051] Specifically, for the power transmission cable connected to the electromagnetic coil 42 of the linear generator 4, it needs to be finally output to the outside and connected to the storage battery 202 for power supply. Therefore, the power transmission cable will pass through the wire passing hole, and a sealed connection state is formed between the wire passing hole and the power transmission cable to ensure that there is sufficient air pressure in the airbag to meet the shock absorption requirements.

[0052] Regarding the method of hermetically connecting the power transmission cable, the structural configuration of the conventional cable hermetic connection can be referred to, and no limitation is made here.

[0053] Further, in order for the linear generator 4 to reliably generate electricity in the load-bearing airbag 2, the linear generator 4 can swing between the upper cover 1 and the base 3.

[0054] Specifically, since the load-bearing airbag 2 is overall flexible, during use, in addition to the longitudinal compression or elongation deformation, the load-bearing airbag 2 will also generate a certain amount of lateral deformation. Therefore, for the linear generator 4, corresponding swinging deflection can be generated between the upper cover 1 and the base 3 according to the deformation of the load-bearing airbag 2 to ensure the smoothness of the linear generator 4 during the reciprocating motion for power generation.

[0055] Still further, the power generation assembly further includes a first elastic support member 5 and a second elastic support member 6. The first elastic support member 5 is arranged at the end of the stator, and the second elastic support member 6 is arranged at the end of the rotor outside the stator.

[0056] Specifically, in order to satisfy the requirement that the linear generator 4 can generate corresponding swings according to the deformation state of the load-bearing airbag 2, and at the same time, the requirement that the linear generator 4 can be reliably and stably installed is also satisfied, the first elastic support component 5 and the second elastic support component 6 are respectively provided at both ends of the linear generator 4. The first elastic support component 5 and the second elastic support component 6 can generate corresponding deformations when subjected to force, so that the linear generator 4 generates corresponding swings when the load-bearing airbag 2 is laterally deformed, so as to ensure that the movement direction of the mover in the linear generator 4 is basically consistent with the telescopic direction of the load-bearing airbag 2.

[0057] Among them, according to the installation position of the linear generator 4, the first elastic support component 5 can be set on the upper cover 1, and the second elastic support component 6 can be set on the base 3; or, the second elastic support component 6 can be set on the upper cover 1, and the first elastic support component 5 can be set on the base 3.

[0058] In addition, the elastic supporting component may be represented as a physical body, such as a rubber block or a spring. For example, the first elastic supporting component 5 is a first rubber block; or, the first elastic supporting component 5 is a first spring. Similarly, the second elastic supporting component 6 is a second rubber block; or, the second elastic supporting component 6 is a second spring.

[0059] like Figure 3 As shown, the second elastic support component 6 is a second spring, a connecting plate is provided on the top of the support rod 43, one end of the second spring is fixedly connected to the upper cover 1 by bolts, and the other end is fixedly connected to the connecting plate by bolts. The first elastic support component 5 is a first rubber block, and the two ends of the first rubber block are fixedly connected to the sleeve 41 and the base 3 by bolts.

[0060] like Figure 4 As shown, the first elastic support component 5 is a first spring, the second elastic support component 6 is a second spring, the first spring is connected between the sleeve 41 and the base 3 by bolts, and similarly, the two ends of the second spring are also connected between the upper cover 1 and the support rod 43 by bolt fastening.

[0061] like Figure 5 As shown, the first elastic support component 5 is a first rubber block, and the second elastic support component 6 is a second rubber block. The first rubber block is connected between the sleeve and the base 3 by bolts, and the second rubber block is connected between the upper cover 1 and the support rod 43 by bolts.

[0062] Furthermore, the base 3 is further provided with a mounting slot 31 ; the first elastic supporting component 5 is arranged at the bottom of the mounting slot 31 , and the stator is inserted into the mounting slot 31 .

[0063] Specifically, under normal circumstances, during the operation of the vehicle, due to the undulation of the road surface, the vibration transmitted by the tire will drive the base 3 to have a large bump amplitude. In order to improve the installation reliability, the sleeve 41 of the linear generator 4 is installed on the base 3, while the upper cover 1 is connected to the vehicle body of the car with a relatively small vibration amplitude, so the support rod 43 is connected to the upper cover 1.

[0064] In order to provide good installation and support for the sleeve 41, an installation slot 31 is provided on the base 3, and the closed end of the sleeve 41 will be inserted into the installation slot 31 to install the sleeve 41 more reliably through the installation slot 31. Correspondingly, the first elastic support member 5 is also located in the installation slot 31, and the sleeve 41 and the first elastic support member 5 are connected in the installation slot 31.

[0065] In addition, in order to meet the requirement of the swing of the sleeve 41, the installation slot 31 is in a flared structure.

[0066] Furthermore, in order to control the maximum compression stroke of the load-bearing airbag 2 to ensure the use reliability, a first elastic stop member 87 is further provided on the upper cover 1; and / or, a second elastic stop member is provided on the base 3.

[0067] Specifically, during the compression process of the load-bearing airbag 2, the elastic stop member provided in the load-bearing airbag 2 can play a limiting role, and the elastic stop member can be supported by materials such as rubber. That is, when the load-bearing airbag 2 is compressed to the maximum position, the elastic stop member will be squeezed between the upper cover 1 and the base 3. On the one hand, the elastic stop member can play a limiting role to protect the load-bearing airbag 2, and on the other hand, the elastic stop member can also play a shock-absorbing role in the compression limit state.

[0068] Among them, the first elastic stop member 87 is in a ring structure and surrounds the outside of the linear generator 4, or the first elastic stop member 87 includes a plurality of first elastic blocks distributed outside the linear generator 4. Similarly, the second elastic stop member is in a ring structure and surrounds the outside of the linear generator 4, or the second elastic stop member includes a plurality of second elastic blocks distributed outside the linear generator 4.

[0069] Based on the above technical solutions, optionally, the guide arm 101 is further provided with a hydraulic shock absorber 103. Specifically, the hydraulic shock absorber 103 can further provide sufficient shock absorption and buffering effect to make the vehicle have a better shock absorption effect during driving.

[0070] Similarly, a rotatable connection seat 104 is further provided at the end of the guiding arm 101 away from the connecting frame 102. The provision of the connection seat 104 can more conveniently rotatably mount the guiding arm 101 on the vehicle body of an automobile.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
