Description

Technical Field

[0001] This utility model relates to the field of vehicle suspension technology, and in particular to an air suspension lifting device. Background Technology

[0002] The suspension is a general term for the force transmission connection device between the car frame and the axle or wheels. Its function is to transmit the force and torque acting between the wheels and the frame, and to buffer the impact force transmitted from the uneven road surface to the frame or body, and to dampen the vibration caused thereby, so as to ensure the smooth driving of the car.

[0003] To improve driving comfort, most vehicles are now equipped with air suspension systems. Existing air suspension systems mainly rely on the expansion and contraction of air springs to change the height of the vehicle's suspension. However, since air springs are mainly made of rubber, when a car is in motion, the lack of external protective devices for the air springs may cause them to be damaged by falling rocks, leading to traffic accidents and affecting driving safety.

[0004] Therefore, it is necessary to develop an air suspension lifting device to solve the above problems. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide an air suspension lifting device.

[0006] This utility model is achieved through the following technical solution:

[0007] An air suspension lifting device is installed on the vehicle frame and includes: an airbag, a mounting component, a telescopic component, and a connecting component;

[0008] The mounting component is connected to the vehicle frame, the telescopic assembly and the mounting component are connected through the connecting assembly, and the telescopic assembly and the mounting component form a receiving space after being connected, and the airbag is disposed in the receiving space;

[0009] One end of the airbag can abut against the mounting component. As the airbag height changes with the change in inflation volume, the mounting component moves in coordination with the vehicle frame under the influence of the airbag height change, and drives the telescopic component to move to change the height of the accommodating space.

[0010] In one possible implementation, the connecting component includes a locking member, and the telescopic component includes a snap-fit ​​member, the locking member engaging with the snap-fit ​​member.

[0011] In one possible implementation, the snap-fit ​​element includes a snap fastener that snaps into the locking element.

[0012] In one possible implementation, the connecting assembly further includes a traction member and a connector, one end of the connector being connected to the clamping member and the other end of the connector being connected to the traction member, the traction member being able to drive the clamping member to move to separate from the telescopic assembly.

[0013] In one possible implementation, the connecting assembly includes an elastic element and a receiving element, one end of the elastic element being connected to the clamping element and the other end of the elastic element being connected to the receiving element, the elastic element being able to limit the relative position of the clamping element and the receiving element to achieve the engagement of the clamping element and the engaging element.

[0014] In one possible implementation, at least two connecting components are provided on the side of the mounting member near the telescopic assembly. The at least two connecting components include a first connecting component and a second connecting component, which are symmetrically arranged along the axial direction of the telescopic assembly.

[0015] In one possible implementation, at least two connecting components are provided on the side of the mounting member near the telescopic assembly. The at least two connecting components include a first connecting component and a second connecting component, which are symmetrically arranged along the axial direction of the telescopic assembly.

[0018] In one possible implementation, the device further includes a guide connected to the telescopic assembly and a fastener connected to the vehicle frame; one end of the guide opposite to the telescopic assembly is slidably connected to the fastener.

[0019] The fastener is capable of moving with the frame and sliding relative to the guide.

[0020] This utility model has the following beneficial effects:

[0021] This utility model discloses an air suspension lifting device, including an airbag, a mounting component, a telescopic component, and a connecting component. The mounting component is connected to the vehicle frame, and the telescopic component and the mounting component are connected via the connecting component. The connection of the telescopic component and the mounting component forms a receiving space, in which the airbag is placed. One end of the airbag can abut against the mounting component. As the airbag's height changes with its inflation volume, the mounting component moves in tandem with the vehicle frame under the influence of this height change, and also moves the telescopic component to alter the height of the receiving space. By employing this air suspension lifting device, where the telescopic component and the mounting component form a receiving space, and the airbag is placed within this space, the airbag is protected. When the airbag's height changes, the mounting component moves the telescopic component, thus changing the height of the receiving space.

[0029] The embodiments are described below with reference to the accompanying drawings, which do not limit the disclosure described in the claims.

[0030] The following is in conjunction with the appendix Figure 1 This invention introduces an air suspension lifting device provided in an embodiment of the present invention, which is installed on the vehicle frame and includes: an airbag 1, a mounting component 2, a telescopic component 3, and a connecting component 4;

[0031] Mounting component 2 is connected to the frame. Telescopic component 3 and mounting component 2 are connected by connecting component 4. After the telescopic component 3 and mounting component 3 are connected, they form a receiving space. Airbag 1 is set in the receiving space.

[0032] One end of the airbag 1 can abut against the mounting component 2. As the airbag 1 changes height with its inflation volume, the mounting component 2 moves in tandem with the vehicle frame, causing the telescopic assembly 3 to move and change the height of the receiving space. By employing the aforementioned air suspension lifting device, where the telescopic assembly and mounting component form a receiving space, and the airbag is placed within this space, the airbag is protected. When the airbag height changes, the mounting component moves the telescopic assembly, thus changing the height of the receiving space. This further protects the airbag during vehicle operation, preventing traffic accidents caused by airbag damage and improving vehicle safety.

[0033] In some embodiments, the connecting component 4 includes a locking member 401, and the telescopic component 3 includes a snap-fit ​​member 31, with the locking member 401 snapping into the snap-fit ​​member 31. By using a snap-fit ​​connection to connect the connecting component 4 and the telescopic component 3, the disassembly and installation of the device become more convenient.

[0039] In some embodiments, the telescopic component 3 includes a fixing member 32 and a movable member 33 slidably connected to the fixing member 32. One end of the movable member 33 is connected to the mounting member 2. When the mounting member 2 moves with the change in height of the airbag 1, the movable member 33 can slide relative to the fixing member 32 to change the height of the accommodating space. By adopting this arrangement, when the height of the airbag 1 changes, the mounting member 2 can drive the telescopic component to move with the airbag, thereby enabling timely changes in the height of the accommodating space.

[0040] In some embodiments, the device further includes an inflation assembly 5, which has an air outlet, and the airbag 1 has an air inlet. The air outlet and the air inlet are connected to form an air intake channel. By using the inflation assembly 5, gas can be injected into or extracted from the airbag 1 in a timely manner to adjust the height of the airbag, thereby reducing vibrations during vehicle operation and making the vehicle ride more smoothly.
