Description

Separable airbags and bicycles Technical Field

[0001] This invention relates to the technical field of airbags, and more particularly to a detachable airbag and a bicycle. Background Technology

[0002] Existing motorcycle airbags are installed at the front or sides of the motorcycle. When a motorcycle is involved in a collision, the airbag deploys to protect the rider and prevent them from colliding with the front of the motorcycle.

[0003] However, riders often get thrown from motorcycles because existing airbags are fixedly attached to the motorcycle. Therefore, when a rider is thrown from the motorcycle, the airbag fails to provide protection.

[0004] Therefore, it is necessary to design a separable airbag and bicycle that can separate from the vehicle body when the rider is ejected. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detachable airbag and bicycle that can separate from the vehicle body when the rider is ejected.

[0006] The present invention provides a detachable airbag, including an inflator and an air bag. The inflator is connected to the air bag. The airbag also includes a connector and a generator. The connector is used to connect the air bag to the vehicle body. The generator is installed on the vehicle body at a position corresponding to the connector. When the generator is ignited, the generator destroys the connector, and the air bag separates from the vehicle body.

[0007] Furthermore, it also includes a control unit, which, in the event of a vehicle collision, controls the inflator to inflate the airbag, and after the airbag is deployed, controls whether the generator is ignited.

[0008] Furthermore, the connector is provided with weakening points, which are destroyed when the generator is ignited.

[0009] Furthermore, the connector includes at least two webbing strips wrapped around the air bag and the vehicle body.

[0010] Furthermore, the air bag is mounted on the inflator via a belt loop.

[0011] The present invention also provides a bicycle, including a frame and a detachable airbag as described in any of the preceding claims.

[0012] Furthermore, the frame includes a front crossbar, and the connector is connected to the front crossbar.

[0013] Furthermore, it also includes a long strip-shaped bracket, which is fixedly connected to the front crossbar, and the connector includes at least two webbings, which are wrapped around the air bag and the bracket.

[0014] Furthermore, the air bag is mounted on the inflator via a belt loop, and the bracket separates the belt loop from the generator.

[0015] Furthermore, the loop is located between the two webbing strips.

[0016] The above technical solution has the following beneficial effects:

[0017] In this invention, when the generator is ignited, the generator destroys the connector, the air bag separates from the vehicle body, and the air bag can fly out with the rider, avoiding collision between the rider and the ground or the surrounding environment. Attached Figure Description

[0025] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0026] It is readily understood that, based on the technical solution of this invention, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of the invention.

[0027] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0028] In one embodiment of the present invention, as shown in Figures 1-2, the detachable airbag includes an inflator 1 and an air bag 2. The inflator 1 is connected to the air bag 2. The airbag also includes a connector 3 and a generator 4. The connector 3 is used to connect the air bag 2 to the vehicle body 10. The generator 4 is installed on the vehicle body 10 at a position corresponding to the connector 3. When the generator 4 is ignited, the generator 4 destroys the connector 3, and the air bag 2 separates from the vehicle body 10.

[0029] Specifically, as shown in Figure 1, the inflator 1 is cylindrical, and the air bag 2 is fixedly connected to the inflator 1 after being rolled up.

[0030] As shown in Figure 3, under normal circumstances, air bag 2 does not deploy.

[0031] As shown in Figure 4, when the vehicle body 10 collides, the inflator 1 is detonated, inflating the air bag 2. The air bag 2 unfolds towards the rider and surrounds the rider to protect their body.

[0032] In this embodiment, as shown in Figure 2, a connector 3 and a generator 4 are also included. When the airbag 2 is deployed, if it is determined that the vehicle body 10 may overturn or the bicycle may detach from the vehicle body 10 and fly out, the generator 4 is ignited. The generator 4 destroys the connector 3, causing the airbag 2 to separate from the vehicle body 10 at this time.

[0033] As shown in Figure 5, the airbag 2 detaches from the vehicle body 10 along with the rider. The airbag 2 can continue to protect the rider and reduce the collision between the rider and the ground.

[0034] Therefore, in this embodiment, the air bag 2 can separate from the vehicle body 10 along with the rider, thus better protecting the human body.

[0035] Furthermore, it also includes a control unit. When the vehicle body 10 collides, the control unit controls the inflator 1 to inflate the airbag 2. After the airbag 2 deploys, the control unit controls whether the generator 4 is ignited. The control unit is connected to multiple sensors that can detect the vehicle's acceleration, deceleration, collision intensity, pressure, etc. For example, when an accident occurs, the acceleration sensors located on the front and rear suspensions of the vehicle body will detect sudden deceleration or acceleration changes, the pressure sensors on the seat will detect a sudden decrease in gravity, and the pressure sensors on the handlebars will detect a sudden decrease in grip strength. When these detected values ​​all reach preset thresholds, the control unit will consider the collision to be severe enough and the rider to be ejected, requiring the generator 4 to be ignited to separate the airbag 2.

[0036] Furthermore, the connector 3 has a weakening point, which is destroyed when the generator 4 is ignited. As shown in Figure 1, the generator 4 is installed at the position corresponding to the connector 3, and the weakening point of the connector 3 is designed to be close to the generator 4. When the generator 4 is ignited, the weakening point of the connector 3 can be burned off or blown off by high temperature, thereby causing the connector 3 to break and ultimately causing the airbag 2 to separate from the vehicle body 10.

[0037] Preferably, as shown in Figure 2, the connector 3 includes at least two webbing strips wrapped around the air bag 2 and the vehicle body 10.

[0038] Alternatively, the connector 3 can also be made of plastic strips, and there can be two or three connectors 3.

[0039] Furthermore, as shown in Figure 2, the air bag 2 is mounted on the inflator 1 via a belt loop 5. Specifically, the inflator 1 is cylindrical, and the air bag 2 is fitted onto the inflation port of the inflator 1 and secured by the belt loop 5, thus connecting the air bag 2 to the inflator 1. The belt loop 5 is unaffected by the generator 4, and the air bag 2 remains attached to the inflator 1.

[0040] In another embodiment of the invention, the bicycle includes a frame and a detachable airbag as described above.

[0041] Furthermore, as shown in Figure 1, the frame includes a front crossbar 101, and the connector 3 is connected to the front crossbar 101. The front crossbar 101 is located at the front of the vehicle, and when the airbag 2 is deployed, it is convenient to deploy towards the rider's head and upper body.

[0042] Furthermore, as shown in Figure 1, it also includes a long strip-shaped bracket 102, which is fixedly connected to the front crossbar 101. The connector 3 includes at least two webbings, which are wrapped around the air bag 2 and the bracket 102.

[0043] Specifically, the bracket 102 is a long, flat rod, and the bracket 102 can be welded to or bolted to the front crossbar 101. The generator 4 is mounted on the bracket 102 and corresponds to the position of the connector 3. The connector 3 is wrapped around the outside of the air bag 2 and the bracket 102, connecting the air bag 2 to the bracket 102.

[0044] Furthermore, as shown in Figure 1, the air bag 2 is mounted on the inflator 1 via a loop 5, and a bracket 102 separates the loop 5 from the generator 4. When the generator 4 is ignited, the bracket 102 prevents the loop 5 from being damaged.

[0045] Alternatively, the loop 5 may be made of webbing, plastic tape, or metal ring.

[0046] Preferably, as shown in Figure 2, the loop 5 is located between the two webbings, making the overall structure more compact, while the position of the webbings also reduces the impact on the deployment of the air bag 2.

[0047] In this invention, when the generator is ignited, it breaks the connector, the air bag separates from the vehicle body, and the air bag can fly out with the rider, avoiding collisions between the rider and the ground or the surrounding environment.

[0048] The vehicle in this invention can be a bicycle, an electric vehicle, a motorcycle, or a tricycle, etc.

[0049] The above description is merely the principle and preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principle of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
