Description

Technical Field

[0001] The present application relates to the technical field of airbag support installation, and in particular to an airbag support installation and positioning mechanism. Background Art

[0002] An airbag support is a device that uses the elasticity and supporting properties of an airbag to carry loads. It is mainly composed of an airbag, an upper cover and a lower cover. The airbag is usually made of elastic materials such as rubber and can be filled with gas such as air or nitrogen. The upper cover and the lower cover are generally made of metal. Their function is to seal the airbag and provide an interface for connecting to external structures. The upper cover is used to connect the supported equipment, and the lower cover is connected to the base ground or other supporting structures. It is also widely used in transportation vehicles such as cars, trains, and airplanes. Taking cars as an example, airbag supports can be used to support car seats. By adjusting the air pressure in the airbag, the height and hardness of the seat can be changed to improve riding comfort. In the suspension systems of some high-end cars, airbag supports are also used to provide better shock absorption and enhance vehicle driving stability.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the airbag support will perform frequent compression and stretching movements during operation, and the impact force of each movement will be very large, which will cause a large pulling force on the connection. After long-term use, the support connection between the airbag support and the car seat will be damaged, making it inconvenient to position and install the airbag support at the support connection of the car seat, which may easily lead to safety hazards, so it needs to be improved. Utility Model Content

[0004] The purpose of the present application is to provide an airbag support installation and positioning mechanism to improve the problem of inconvenience in positioning and installing the airbag support at the support connection of the car seat.

[0005] The present application provides an airbag support installation and positioning mechanism that adopts the following technical solutions:

[0006] An airbag support mounting and positioning mechanism comprises a plurality of support plates, one end of each of the plurality of support plates being fixedly connected to a plurality of clamping devices, and one end of the opposite surfaces of the plurality of support plates being commonly fixedly connected to a rubber airbag. When the airbag support is impacted by an external force, the force is transmitted to the support plate. One end of each of the plurality of support plates is threadedly inserted with a plurality of first bolts distributed in a rectangular array, and the first bolts on the support plate preliminarily fix the entire mechanism. The clamping device comprises a housing, one end of the housing being movably connected to a pull rod, one end of the pull rod being fixedly connected to the pull plate, a first spring being sleeved on the outer surface of the pull rod, the upper and lower ends of the first spring being fixedly connected to the upper inner wall of the housing and the top end of the bottom plate, respectively. One end of the support plate is provided with a plurality of through slots distributed in a rectangular array, the inner wall of the through slot is fixedly connected to a plurality of connecting shells distributed in a rectangular array, a second spring is fixedly connected to an inner wall of one side of the connecting shell, one end of the second spring is fixedly connected to a limiting bead, a plurality of limiting slots for cooperating with the limiting bead are provided on the lower portion of the outer surface of the pull rod, and one end of the opposite surfaces of the plurality of support plates are commonly fixedly connected to a buffer device.

[0007] Optionally, the buffer device includes multiple base plates, one end of the base plate is fixedly connected to one end of the shell, the outer surface of the pull rod is slidably connected to the inner wall of one end of the base plate, and one end of the opposite surfaces of the multiple base plates is commonly fixedly connected to multiple hydraulic rods distributed at equal intervals. After the base plate is subjected to force, the multiple hydraulic rods distributed at equal intervals begin to play a role, and the hydraulic rods absorb part of the impact force through the compression and flow of the internal hydraulic oil to slow down the transmission of the force. One end of the opposite surfaces of the multiple base plates is slidably connected to multiple fixed frames, and the multiple base plates Slide grooves are provided on both sides of one end of the opposite surface, and the outer surface of the fixed frame is slidably connected to the slide grooves. The inner walls on both sides of the fixed frame are rotatably connected to connecting rods. When the base plate moves under force, the fixed frame slides in the slide groove, and the connecting rods on the inner walls on both sides of the fixed frame rotate with the movement of the fixed frame. The ends of the opposite surfaces of the connecting rods located in the same horizontal plane are rotatably connected to the support rods. The connecting rods will drive the support rods to rise and fall when stretched and compressed, and the support rods play the role of stabilizing the connecting rods. One end of the opposite surfaces of every two adjacent connecting rods are rotatably connected.

[0008] In summary, this application includes at least one of the following beneficial technical effects:

[0009] The utility model achieves the purpose of facilitating the positioning and installation of the airbag support at the support connection of the car seat by means of the elastic force of the second spring pushing the limiting bead into the limiting groove when the limiting groove on the pull rod moves to a position aligned with the limiting bead, thereby fixing the pull rod in the connecting shell.

DETAILED DESCRIPTION

[0014] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0015] An airbag support installation and positioning mechanism, referring to Figure 1 and Figure 2 , including multiple support plates 1, one end of the opposite surfaces of the multiple support plates 1 is commonly connected to the rubber airbag 4 by welding, one end of the multiple support plates 1 is provided with a plurality of first bolts 5 distributed in a rectangular array by threaded insertion, one end of the multiple support plates 1 is fixedly connected to a plurality of clamping devices 3, the clamping device 3 includes a shell 31, one end of the shell 31 is movably connected with a pull rod 32, the outer surface of the pull rod 32 is slidably connected to the inner wall of one end of the bottom plate 21, one end of the pull rod 32 is connected to the pull plate 33 by welding, the outer surface of the pull rod 32 is sleeved with a first spring 34, the upper and lower ends of the first spring 34 are respectively connected to the upper inner wall of the shell 31 and the top of the bottom plate 21 by welding, one end of the support plate 1 is provided with a plurality of through slots 35 distributed in a rectangular array, the through slots 35 The inner wall is connected to multiple connecting shells 36 distributed in a rectangular array by welding. Pulling the pull plate 33 drives the pull rod 32 to move outward. The first spring 34 sleeved on the pull rod 32 is compressed to store elastic potential energy, and the pull rod 32 is inserted into the connecting shell 36 in the through groove 35 on the support plate 1. The inner wall of one side of the connecting shell 36 is connected to the second spring 37 by welding, and one end of the second spring 37 is connected to the limiting bead 38 by welding. A plurality of limiting grooves 39 for cooperating with the limiting beads 38 are provided on the lower part of the outer surface of the pull rod 32. When the limiting groove 39 on the pull rod 32 moves to a position aligned with the limiting bead 38, the elastic force of the second spring 37 pushes the limiting bead 38 to be stuck in the limiting groove 39, and one end of the opposite surfaces of multiple support plates 1 is fixedly connected with a buffer device 2.

[0016] Reference Figure 3The buffer device 2 includes multiple bottom plates 21, one end of the bottom plate 21 is connected to one end of the shell 31 by welding, and one end of the opposite surface of the multiple bottom plates 21 is connected to multiple hydraulic rods 26 distributed at equal intervals by welding. After the bottom plate 21 is subjected to force, the multiple hydraulic rods 26 distributed at equal intervals begin to play a role. The hydraulic rods 26 absorb part of the impact force through the compression and flow of the internal hydraulic oil to slow down the transmission of force. One end of the opposite surface of the multiple bottom plates 21 is slidably connected to multiple fixed frames 23. Both sides of the one end of the opposite surface of the multiple bottom plates 21 are provided with slide grooves 22, and the outer surface of the fixed frame 23 slides with the slide groove 22 When the bottom plate 21 is moved by force, the fixed frame 23 slides in the slide groove 22, and the connecting rods 24 on the inner walls on both sides of the fixed frame 23 rotate with the movement of the fixed frame 23. The inner walls on both sides of the fixed frame 23 are rotatably connected with the connecting rods 24, wherein the ends of the opposite surfaces of the connecting rods 24 located in the same horizontal plane are rotatably connected with the support rods 25 together, and the ends of the opposite surfaces of every two adjacent connecting rods 24 are rotatably connected to form a deformation similar to a truss structure, thereby further dispersing and absorbing impact force. When the connecting rods 24 located in the same horizontal plane rotate relative to each other, the support rods 25 connected by common rotation play a role in supporting and stabilizing the structure of the connecting rods 24.

[0017] Working principle: When it is necessary to fix the airbag support installation positioning mechanism in a specific position, the entire mechanism is initially fixed to the installation foundation by the first bolt 5 on the support plate 1, and the clamping device 3 begins to work, pulling the pull plate 33, driving the pull rod 32 to move outward, and the first spring 34 sleeved on the pull rod 32 is compressed, storing elastic potential energy, and inserting the pull rod 32 into the connecting shell 36 in the through groove 35 on the support plate 1. When the pull rod 32 is inserted, the second spring 37 on the inner wall of one side of the connecting shell 36 is in a compressed state, and the limiting bead 38 is pressed into the inside of the connecting shell 36. When the limiting groove 39 on the pull rod 32 moves to a position aligned with the limiting bead 38, the elastic force of the second spring 37 pushes the limiting bead 38 to snap into the limiting groove 39, so that the pull rod 32 is fixed in the connecting shell 36, thereby achieving the purpose of facilitating the positioning and installation of the airbag support at the support connection of the car seat;

[0018] When the airbag support is impacted by external force, the force is first transmitted to the support plate 1, and the support plate 1 transmits the force to the bottom plate 21 of the buffer device 2 connected to it. After the bottom plate 21 is subjected to force, multiple hydraulic rods 26 distributed at equal intervals begin to play a role. The hydraulic rods 26 absorb part of the impact force through the compression and flow of the internal hydraulic oil, slowing down the transmission of force, and the fixed frame 23 slidingly connected on the bottom plate 21 also starts to move. When the bottom plate 21 is moved by force, the fixed frame 23 slides in the slide groove 22, and the connecting rods 24 on the inner walls on both sides of the fixed frame 23 rotate with the movement of the fixed frame 23. Every two adjacent connecting rods 24 rotate relative to each other, forming a deformation similar to a truss structure, thereby further dispersing and absorbing the impact force. When the connecting rods 24 located in the same horizontal plane rotate relative to each other, the support rods 25 connected by common rotation play the role of supporting and stabilizing the connecting rod 24 structure. The airbag support can absorb impact force and enhance the buffering effect.
