Description

Technical Field

[0001] This application relates to the field of automotive technology, and more specifically, to a quick-release structure for an airbag, a steering wheel, and an automobile. Background Technology

[0002] Currently, there are two main ways to fix car airbags to the steering wheel; one of them is to use bolts, which means that the airbag is fixed and installed by tightening the bolts, and disassembled by loosening the bolts. This method has the following drawbacks: 1. Excessive tightening force of the bolts can damage the steering wheel connecting parts; 2. Over time, during the bolt disassembly process, the bolts may strip, break, or the top of the bolt may strip under the action of a wrench, making it impossible to disassemble.

[0003] The second method uses clips and hooks for fixing and installation. This method is simple and quick to install, but difficult to disassemble later. Because the clips are inside the steering wheel and cannot be seen during disassembly, and the space behind the steering wheel is narrow, a small flathead screwdriver must be used to try to disassemble it blindly from behind the steering wheel. Only experienced technicians can disassemble it. Disassembly also requires rotating the steering wheel multiple times, which is not only complicated but also difficult.

[0004] Both of the above methods have operational problems during installation and assembly, and cannot guarantee the safety effect of the steering wheel airbag when in use. Summary of the Invention

These terms are only used to distinguish the descriptions. For example, first may also be referred to as second without departing from the scope of the embodiments of this application, and similarly, second may also be referred to as first.

[0062] A quick-release structure for an airbag includes a first connecting component 3, a second connecting component 4, a retaining ring 6, and at least two locking components 8.

[0063] The quick-release structure for the airbag of the present invention is set between the steering wheel base 1 and the steering wheel top plate 2. The steering wheel base 1 and the steering wheel top plate 2 are separated by a first connecting component 3 and a second connecting component 4. The airbag 7 can be clamped between the steering wheel base 1 and the steering wheel top plate 2 and is kept locked under the action of the locking component 8. The locking force of the airbag 7 can be adjusted by the locking component 8. The installation and disassembly process is very convenient. It is only necessary to manually open the steering wheel top plate 2 and loosen the locking component 8.

[0064] Compared with the prior art, the present invention allows for manual installation and removal of the airbag 7, simplifying the operation steps and making it easy to operate.

[0065] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] like Figure 1 The invention discloses a quick-release structure for an airbag, comprising a plurality of first connecting components 3, which are evenly arranged circumferentially along the upper surface of a steering wheel base 1. In this application, four first connecting components 3 are provided. Each first connecting component 3 includes a hollow connecting sleeve 31. Correspondingly, a second connecting component 4 is disposed on the lower surface of the steering wheel top plate 2 and is installed and positioned in conjunction with the first connecting components 3. The second connecting component 4 and the first connecting component 3 are fixed by insertion. The second connecting component 4 includes a connecting rod 41, which is inserted into the connecting sleeve 31.

[0067] Furthermore, a limiting device is also provided between the first connecting component 3 and the second connecting component 4; the limiting device limits the insertion depth between the connecting sleeve 31 and the connecting rod 41, thereby limiting the distance between the steering wheel top plate 2 and the steering wheel base 1; specifically, the limiting device includes a limiting slot provided on the upper side wall of the inner cavity of the connecting sleeve 31 and a limiting block provided on the bottom of the connecting rod 41; the limiting block is inserted into the limiting slot, and the limiting block is threaded to the bottom of the connecting rod 41. This application can select the corresponding limiting block according to different sizes of airbags 7.

[0068] Furthermore, this application also includes a fixing ring 6, which is disposed on the upper surface of the steering wheel base 1 and can be used to install an airbag 7 inside and a second connecting component 4 outside; at least two locking components 8 are evenly arranged on the side wall of the fixing ring 6; the locking components 8 cooperate with the steering wheel top plate 2 and the steering wheel base 1 to keep the airbag in a locked state.

[0069] The locking components 8 described in this application are four in number. Each locking component 8 includes a threaded sleeve 81 fixedly disposed on the side wall of the fixing ring 6, a threaded rod 82 threadedly connected to the threaded sleeve 81, a locking clamp 83 movably disposed at one end of the threaded rod 82, a locking screw 84 fixedly disposed at the other end of the threaded rod 82, and limiting rods 85 respectively disposed on both sides of the threaded rod 82. Specifically, the locking clamp 83 is connected to the threaded rod 82 via a bearing, wherein the bearing is embedded in the outer surface of the locking clamp 83 and rotatably connected to the threaded rod 82; the locking clamp 83... Under the action of the two limiting rods 85, the threaded rod 82 will not rotate freely when it rotates; the inner surface of the locking clamp 83 is curved, and a rubber gasket is provided on the inner surface of the locking clamp 83; in use, the inner surface of the locking clamp 83 can press against the circumferential outer surface of the airbag 7, thereby locking the airbag 7, and at the same time, due to the setting of the rubber gasket, scratches on the airbag 7 are avoided; the two limiting rods 85 are slidably sleeved on the fixing ring 6, and the front ends are fixedly connected to the locking clamp 83, and can move synchronously under the drive of the locking clamp 83.

[0070] The outer circumferential surface of the locking screw 84 is provided with an anti-slip component; the anti-slip component can be an anti-slip protrusion or an anti-slip texture. In this embodiment, the anti-slip component is an anti-slip texture.

[0071] The threaded sleeve 81 includes a first fixing part 810 fixedly disposed on the outer surface of the fixing ring 6, a second fixing part 811 fixedly disposed on the inner surface of the fixing ring 6, and a connecting part disposed on the fixing ring 6; specifically, the first fixing part 810 and the second fixing part 811 are fixedly connected to both ends of the connecting part respectively, and the connecting part is threadedly connected and fixed to the threaded rod 82.

[0072] In use, manually turn the locking screw 84 to rotate the threaded rod 82, which in turn moves the locking clamp 83 forward or backward to lock or release the airbag 7.

[0073] The present invention also provides a steering wheel using the above embodiments, including the quick-release structure for the airbag, an airbag mounting 7, a steering wheel base 1, and a steering wheel top plate 2;

[0074] The airbag is clamped between the steering wheel base 1 and the steering wheel top plate 2, and is locked and fixed by the locking component 8.

[0075] Specifically: the steering wheel base 1 is a circular structure; in this application, the lower surface of the steering wheel top plate 2 is a planar design structure; the advantage of this design is that, combined with the setting of the first connecting part 3 and the second connecting part 4, the airbag 7 is sandwiched between the steering wheel top plate 2 and the steering wheel base 1, thereby facilitating disassembly.

[0076] This application also provides a safety detection component 5 on the steering wheel base 1. The safety detection component 5 can contact the bottom of the airbag 7 and is used to detect the pressure value at the installation position of the airbag 7. In this application, the safety detection component 5 is a pressure sensor.

[0077] It should be noted that because the airbag 7 is a fabric bag formed by vacuum sealing, different airbags 7 will have slight variations in thickness. If the thickness is too high or too low, it will not reach the preset pressure value. Only when the preset pressure value is reached will the airbag 7 deploy at the optimal speed and amplitude. It can deploy if the pressure value is not reached or is higher than the pressure value, but it will not achieve the desired effect of protecting the driver and will instead increase the risk of injury to the driver.

[0078] It should be further explained that, since the airbag 7 is a fabric bag formed by vacuuming, its thickness and diameter will change accordingly when it is subjected to external compression.

[0079] This application adjusts the pressure value of the airbag 7 at the installation position by means of locking component 8; when the pressure sensor determines that the bottom pressure of the airbag 7 is too high during the assembly process, the clamping force of the locking plate 83 on the airbag 7 can be reduced by rotating the locking screw 84 in the opposite direction, thereby reducing the pressure value of the airbag 7; the advantage of this design is that, through the joint action of multiple locking components 8 with the steering wheel base 1 and the steering wheel top plate 2, the installation position of the airbag 7 is in the designed position, thereby achieving the best protection effect for the driver.

[0080] Furthermore, a control box 9 is provided on the top plate 2 of the steering wheel; a display module 10 and an operation panel 11 are provided on the upper surface of the control box 9; the display module 10 is electrically connected to the safety detection component 5 and is used to display the pressure detected by the safety detection component 5; an adjustment button 12 is provided on the operation panel 11 and is used to adjust the pressure threshold of the safety detection component 5.

[0081] The steering wheel used in this invention facilitates the fixing of the airbag 7, making it easy to install and remove and highly flexible. In addition, by setting a safety detection component 5 at the connection between the airbag 7 and the steering wheel base 1, the pressure detection of the installation position of the airbag 7 is realized, thus providing driver safety.

[0082] The present invention also provides a vehicle using the above embodiments, the vehicle including the aforementioned steering wheel.

However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.
