Description

Technical Field

[0001] This utility model relates to the field of side airbag rolling technology, specifically to a side airbag rolling device. Background Technology

[0002] The side airbag includes a gas generator and an air bag mounted on the gas generator. The air bag needs to be rolled up during storage. The structure of the gas generator is as follows: Figure 1 As shown, it includes a cylindrical body 201 and a stud 202 disposed on the body 201.

[0003] Existing side airbag rewinding devices typically include a clamping mechanism and a rewinding mechanism. The clamping mechanism holds the gas generator, and the rewinding mechanism rewinds the airbag 203. However, existing clamping mechanisms usually only clamp the main body 201 of the gas generator. Since the main body 201 of the gas generator is cylindrical, and to avoid excessive clamping force that could cause wear on the outer circumference of the main body 201, the clamping force of the clamping mechanism on the main body 201 is limited. During clamping, the main body 201 of the gas generator is prone to rotation, resulting in unstable clamping of the gas generator, which in turn reduces the rewinding efficiency of the airbag 203. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a side airbag retraction device, comprising:

[0005] A support frame is provided with a clamping assembly and a mounting block. The clamping assembly includes a gripper cylinder connected to the support frame. The output end of the gripper cylinder is provided with a first clamping plate and a second clamping plate arranged opposite to each other. The gripper cylinder is used to drive the first clamping plate and the second clamping plate to clamp the main body of the gas generator. A telescopic cylinder is connected to the second clamping plate. The output end of the telescopic cylinder is provided with a locking plate. The telescopic cylinder is used to drive the locking plate to lock the stud of the gas generator. A tensioning plate is provided on the mounting block, and an air bag is wound around the tensioning plate.

[0006] The winding assembly includes a movable rotary motor and a clamping module disposed at the output end of the rotary motor. The clamping module is used to clamp the air bag, and the rotary motor is used to drive the clamping module to clamp the air bag and wind it up.

[0007] Furthermore, both the first clamping plate and the second clamping plate are provided with arc-shaped plates at their ends, and the two arc-shaped plates are arranged opposite each other and both arc-shaped plates are attached to the outer periphery of the main body of the gas generator.

[0008] Furthermore, the card plate is provided with a U-shaped groove that is adapted to the stud of the gas generator.

[0009] Furthermore, the first clamping plate and the second clamping plate are respectively provided with a first through groove and a second through groove, and the clamping plate passes through the first through groove and the second through groove.

[0010] Furthermore, the clamping module includes a second clamping cylinder and two take-up plates disposed at the output end of the second clamping cylinder. The second clamping cylinder is used to drive the two take-up plates to move closer to each other and clamp the air bag.

[0011] Furthermore, the take-up plate is provided with take-up protrusions.

[0012] Furthermore, the mounting block is provided with a mounting slot and a fixing plug, and the tensioning plate is provided with a fixing hole corresponding to the fixing plug. The tensioning plate passes through the mounting slot and is fixed to the mounting block by the fixing plug.

[0013] Furthermore, there are two mounting blocks.

[0014] Furthermore, it also includes a moving module for driving the rotary motor to move. The moving module includes a first lead screw moving mechanism, a second lead screw moving mechanism, and a third lead screw moving mechanism. The output ends of the second lead screw moving mechanism and the first lead screw moving mechanism are connected. The output ends of the third lead screw moving mechanism and the second lead screw moving mechanism are connected. The output end of the third lead screw moving mechanism is provided with a carrier for supporting the rotary motor.

[0015] Furthermore, a detection sensor is provided on the second clamping plate.

[0016] The beneficial effects of this utility model are as follows: by setting the first clamping plate, the second clamping plate and the clamping plate, the main body of the gas generator is clamped while the studs on the main body are limited, preventing the main body from rotating due to limited clamping force. Compared with the prior art, which only clamps the main body of the gas generator, the technical solution of this application clamps the gas generator more stably, thereby reducing the situation where the winding efficiency of the gas bag is reduced due to unstable clamping of the gas generator, and improving the winding efficiency of the gas bag.

Detailed Implementation

[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figure 2 and Figure 4This utility model provides a side airbag winding device 100, including a support frame 10 and a winding assembly. The support frame 10 is provided with a clamping assembly 11 and a mounting block 12. The clamping assembly 11 includes a gripper cylinder 111 connected to the support frame 10. The output end of the gripper cylinder 111 is provided with a first clamping plate 112 and a second clamping plate 113 arranged opposite to each other. The gripper cylinder 111 is used to drive the first clamping plate 112 and the second clamping plate 113 to clamp the main body 201 of the gas generator. A telescopic cylinder 114 is fixedly connected to the second clamping plate 113. The output end of the telescopic cylinder 114 is provided with a locking plate 115. The telescopic cylinder 114 is used to drive the locking plate 115 to lock the stud 202 of the gas generator.

[0029] By using the first clamping plate 112, the second clamping plate 113, and the clamping plate 115, the main body 201 of the gas generator is clamped while the studs 202 on the main body 201 are limited, preventing the main body 201 from rotating due to limited clamping force. Compared with the prior art, which only clamps the main body 201 of the gas generator, the technical solution of this application provides more stable clamping of the gas generator, thereby reducing the reduction in the winding efficiency of the air bag 203 due to unstable clamping of the gas generator and improving the winding efficiency of the air bag 203.

[0030] Please refer to Figure 5 and Figure 6 The first clamping plate 112 and the second clamping plate 113 are respectively provided with a first through groove 1121 and a second through groove 1131, and the clamping plate 115 passes through the first through groove 1121 and the second through groove 1131. Specifically, in order to prevent the clamping plate 115 from being stuck during the relative movement of the first clamping plate 112 and the second clamping plate 113, the length of the first through groove 1121 and the length of the second through groove 1131 are both greater than the height of the clamping plate 115.

[0031] Specifically, both the first clamping plate 112 and the second clamping plate 113 have arc-shaped plates 1122 at their ends. The two arc-shaped plates 1122 are arranged opposite each other and both are in contact with the outer periphery of the main body 201 of the gas generator. The clamping plate 115 has a U-shaped groove 1151 that matches the studs 202 of the gas generator. When the first clamping plate 112 and the second clamping plate 113 clamp the gas generator, the gas generator is placed between the two arc-shaped plates 1122 along the axial direction of the main body 201, and the clamping plate 115 uses the U-shaped groove 1151 to hold the two studs 202 on the main body 201 along the axial direction of the main body 201.

[0032] In order to detect whether the first clamping plate 112 and the second clamping plate 113 are clamping the main body 201 of the gas generator, a detection sensor 1132 is provided on the second clamping plate 113. Specifically, the detection sensor 1132 is a photoelectric sensor.

[0033] Please refer to Figure 4 and Figure 7 The mounting block 12 is equipped with a tension plate 121, and the air bag 203 is wound around the tension plate 121. When the air bag 203 is wound up, one end of the air bag 203 is fixed to the gas generator, and the other end of the air bag 203 is wound around the tension plate 121 and then wound downward through the winding assembly.

[0034] Specifically, the mounting block 12 is provided with a mounting slot 122 and a fixing plug 123. The tensioning plate 121 is detachably connected to the mounting block 12 via the fixing plug 123. The tensioning plate 121 is provided with a fixing hole 1211 corresponding to the fixing plug 123. The tensioning plate 121 passes through the mounting slot 122 along the axial direction of the gas generator body 201, and is then fixed to the mounting block 12 by inserting the fixing plug 123, which is arranged along the radial direction of the gas generator body 201, into the fixing hole 1211. There are two mounting blocks 12, which are located on both sides of the width direction of the clamping plate 115. The position of the tensioning plate 121 corresponds to the position of the winding assembly relative to the clamping plate 115. When winding the gas bag 203, one of the mounting blocks 12 is selected according to the position of the winding assembly relative to the width direction of the clamping plate 115, and the tensioning plate 121 is installed onto the corresponding mounting block 12 via the fixing plug 123.

[0035] Please refer to Figure 3 The winding assembly includes a rotary motor 21 that is movable and a clamping module disposed at the output end of the rotary motor 21. The clamping module is used to clamp the air bag 203, and the rotary motor 21 is used to drive the clamping module to clamp the air bag 203 and wind it up. The clamping module includes a second gripper cylinder 22 and two winding plates 221 disposed at the output end of the second gripper cylinder 22. The second gripper cylinder 22 is used to drive the two winding plates 221 to move closer to each other and clamp the air bag 203.

[0036] Specifically, to increase the stability of the winding plate 221 in winding the air bag 203, a winding protrusion 2211 is provided on the winding plate 221, which is arranged along the moving direction of the winding plate 221. The arrangement of the winding protrusion 2211 increases the friction between the winding plate 221 and the air bag 203, thereby improving the stability of the winding plate 221 in winding the air bag 203 and further improving the winding efficiency.

[0037] Please refer to Figure 3The side airbag rewinding device 100 also includes a moving module 30 for driving the rotary motor 21. The moving module 30 includes a first lead screw moving mechanism 31, a second lead screw moving mechanism 32, and a third lead screw moving mechanism 33. The output end of the second lead screw moving mechanism 31 is connected to the output end of the first lead screw moving mechanism 31, and the output end of the third lead screw moving mechanism 33 is connected to the output end of the second lead screw moving mechanism 32. The output end of the third lead screw moving mechanism 33 is provided with a carrier 34 for supporting the rotary motor 21. Specifically, the first lead screw moving mechanism 31 is arranged along the width direction of the tension plate 121, the second lead screw moving mechanism 32 is arranged along the width direction of the tension plate 121, and the third lead screw moving mechanism 33 is arranged along the thickness direction of the tension plate 121.

[0038] Please refer to Figure 5 and Figure 8 When winding up the gas bag 203, the main body 201 of the gas generator is first clamped by the first clamping plate 112 and the second clamping plate 113 driven by the gripper cylinder 111, and the clamping plate 115 is driven by the telescopic cylinder 114 to clamp the stud 202 of the gas generator through the U-shaped groove 1151. Then, the first lead screw moving mechanism 31, the second lead screw moving mechanism 32 and the third lead screw moving mechanism 33 cooperate to drive the rotary motor 21 to move the clamping module to correspond with the gas bag 203. The end of the gas bag 203 away from the gas generator is wrapped around and pressed onto the tensioning plate 121, and then the two winding plates 221 are clamped by the gripper cylinder 22. Then, the winding plates 221 are driven by the rotary motor 21 to wind up one end of the gas bag 203, and at the same time, the third lead screw moving mechanism 33 drives the winding plates 221 to raise one end of the gas bag 203 to be close to the gas generator.
