[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] An airbag bracket for an air suspension assembly of a new energy passenger vehicle, such as Figure 1-5 As shown, it includes a guide arm 100, the guide arm 100 is provided with two groups, and two groups of torque tubes 110 are provided between the guide arms 100, the surface of the torque tube 110 is provided with an adjustment component 200, and the top side of the guide arm 100 is provided with a fixing component 300, the adjustment component 200 includes a sleeve 210 slidably connected to the surface of the torque tube 110, the top of the sleeve 210 is attached with an arc plate 220, and the two sides of the bottom of the arc plate 220 are welded with a clamping column 230, and the torque tube 110 is provided with a plurality of The dry group matches the fixing groove 231 of the card column 230, and two groups of connecting grooves 241 are opened inside the sleeve 210. L-shaped connecting blocks 240 are slidably arranged on both sides of the connecting grooves 241. Two groups of two-way spring telescopic rods 250 are fixedly connected between the two groups of L-shaped connecting blocks 240. A cross plate 260 is fixedly connected to the top of one group of two-way spring telescopic rods 250. A connecting rod 270 is fixed to the top of the L-shaped connecting block 240. A plurality of reset springs 280 are arranged between the sleeve 210 and the arc plate 220.

[0026] When the length of the torque tube 110 needs to be adjusted, by pressing the connecting rods 270 on both sides, the L-shaped connecting block 240 is driven to slide inside the connecting groove 241, so that the L-shaped connecting block 240 squeezes the bidirectional spring telescopic rod 250, and the fixation of the L-shaped connecting block 240 to the shaft sleeve 210 is released, and then the connecting rod 270 is pulled upward, and the arc plate 220 is driven to move upward and stretch the return spring 280 under the action of the cross plate 260. The arc plate 220 moves upward and drives the clamping column 230 to move synchronously, so that the clamping column 230 is separated from the fixing groove 231, and then the two groups of torque tubes 110 are pulled to move to both sides, and the length of the torque tube 110 is adjusted to the required length. Finally, the clamping column 230 is re-embedded in the fixing groove 231 to complete the fixation. The adjustment of the length of the torque tube 110 helps to maintain the balance and stability of the vehicle body posture, can more flexibly cope with different loads and driving conditions, and enhances the applicability of the device.

[0027] Please refer to Figures 2 to 4 A slider 211 is fixedly connected to the bottom end of the inner wall of the sleeve 210 , and a sliding groove 212 that matches the slider 211 is opened on the surface of the torque tube 110 .

[0028] The cooperation between the slider 211 and the slide groove 212 can effectively prevent the torque tube 110 from rotating during movement.

[0029] Please refer to Figure 3 The top end of the return spring 280 is fixedly connected to the arc plate 220 , and the bottom end of the return spring 280 is fixedly connected to the sleeve 210 .

[0030] The return spring 280 can make the arc plate 220 fit onto the surface of the sleeve 210 to prevent the arc plate 220 from falling off.

[0031] Please refer to Figure 1 and Figure 5 The fixing assembly 300 includes a fixing seat 310 welded to one side of the top end of the guide arm 100, a round block 320 is slidably connected to the inner wall of the fixing seat 310, and spring grooves 311 are provided on both sides of the inside of the fixing seat 310, a clamping block 330 is slidably connected inside the spring groove 311, a horizontal axis 340 is fixed to the end of the clamping block 330 away from the round block 320, a connecting spring 350 is sleeved on the surface of the horizontal axis 340, the top of the round block 320 is fixedly connected to the airbag 120, and clamping grooves 331 matching the clamping block 330 are provided on both sides of the round block 320.

[0032] When the airbag 120 needs to be installed, the staff inserts the airbag 120 and the round block 320 into the fixing seat 310. When the bottom end of the round block 320 contacts the arc surface on the top side of the block 330, the block 330 is moved toward the inner side of the spring groove 311, so that the block 330 squeezes the connecting spring 350 until the block 330 is embedded in the groove 331 inside the round block 320, thereby fixing the guide arm 100 and the airbag 120. This can effectively fix the airbag 120 quickly and accurately at a predetermined position, greatly shortening the installation time. At the same time, the quick and firm fixing method reduces the safety hazards caused by the loosening or falling off of the airbag 120, thereby improving the safety of vehicle driving.

[0033] During use, when the length of the torque tube 110 needs to be adjusted, the connecting rods 270 on both sides are pressed to make the L-shaped connecting block 240 squeeze the bidirectional spring telescopic rod 250, thereby releasing the fixation of the L-shaped connecting block 240 to the shaft sleeve 210, and then the connecting rod 270 is pulled upward to make the clamping column 230 disengage from the fixing groove 231, and the length of the torque tube 110 is adjusted to the required length, and finally the clamping column 230 is re-embedded in the fixing groove 231 to complete the fixation. The adjustment of the length of the torque tube 110 helps to maintain the balance and stability of the vehicle body posture, can more flexibly cope with different loads and driving conditions, enhances the applicability of the device, and is effective for the airbag. When installing 120, when the bottom end of the round block 320 contacts the arc surface on one side of the top end of the block 330, the block 330 is moved to the inner side of the spring groove 311 until the block 330 is embedded in the slot 331 inside the round block 320, thereby achieving fixation between the guide arm 100 and the airbag 120. This can effectively make the airbag 120 be quickly and accurately fixed at a predetermined position, greatly shortening the installation time. At the same time, the quick and firm fixing method reduces the safety hazards caused by the loosening or falling off of the airbag 120, thereby improving the safety of vehicle driving. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
