A safety side bag for two-wheeled vehicles

Abstract

This invention specifically discloses a safety side bag for two-wheeled vehicles, comprising an airtight body and an airtight cover, which are sealed together by an airtight zipper. An inflation device is provided on the top of the airtight cover. The inflation device includes an airbag, an air intake mechanism, and an air outlet mechanism, both of which are fixedly mounted on the airtight cover. The two ends of the airbag are respectively sealed to the air intake and air outlet mechanisms. When the airbag is under negative pressure, external gas enters the airbag through the air intake mechanism. When pressure is applied to the airbag, the gas inside the airbag enters the side bag through the air outlet mechanism. This invention utilizes unidirectional gas flow into the side bag, allowing the inflated side bag to better protect the contents in the event of an accident involving a two-wheeled vehicle, while also providing a buffer space for the vehicle and occupants, increasing safety. Furthermore, the use of gas to inflate the side bag results in low weight and easy portability.

Description

Technical Field

[0001] This invention relates to the field of vehicle accessories technology, specifically to a safety side bag for two-wheeled vehicles. Background Technology

[0002] Currently, two-wheeled vehicles such as motorcycles, electric bikes, and bicycles often require carrying luggage. Most owners equip their vehicles with either hard or soft side cases at the rear. Hard side cases offer better protection for the contents in the event of an accident (such as reversing, skidding, or impact), while soft side cases do not. However, soft side cases are lightweight and easy to carry. Currently, two-wheeled vehicles equipped with soft side cases do not provide adequate protection for the contents or adequate support for the vehicle and occupants in the event of an accident. Most side cases that do achieve this function involve adding hard materials, such as plastic or metal, to a soft body. The biggest drawback of this approach is increased weight. Furthermore, its effectiveness in protecting the contents, the vehicle, and the occupants is limited. Under significant impact, the insufficient structural strength of the side case can lead to substantial deformation, failing to provide adequate protection, and structural components may even deform or be damaged.

[0003] Therefore, it is extremely important to design a side bag that can both carry luggage and prevent deformation in the event of an accident, thus ensuring its protective function. Summary of the Invention

[0004] In view of the shortcomings of existing technologies, such as heavy and inconvenient hard side cases and easily deformed soft side cases that fail to provide protection, this invention provides a safety side case for two-wheeled vehicles to overcome the above-mentioned shortcomings.

[0005] A safety sidebag for a two-wheeled vehicle includes an airtight body and an airtight cover.

[0006] The airtight package and the airtight cover are connected by an airtight zipper.

[0007] An inflation device is provided on the top of the airtight cover;

[0008] The inflation device includes an inflation bladder, an air inlet mechanism, and an air outlet mechanism. The air inlet mechanism and the air outlet mechanism are both fixedly installed on the airtight cover. The two ends of the inflation bladder are respectively sealed to the air inlet mechanism and the air outlet mechanism.

[0009] When the airbag is under negative pressure, outside gas enters the airbag through the air intake mechanism; when pressure is applied to the airbag, the gas inside the airbag enters the side bag through the air outlet mechanism.

[0010] As a preferred embodiment, the intake mechanism includes a first fixed seat and a first valve seat;

[0011] The first fixing seat is disposed on the inner side wall of the airtight cover, and the first valve seat is disposed on the outer side wall of the airtight cover;

[0012] The first fixed seat and the first valve seat are connected;

[0013] The first valve seat has a hinge groove at one end, a knurled shaft is provided in the hinge groove, and a leak-proof cover is hinged on the knurled shaft.

[0014] The other end of the first valve seat is provided with a first airtight sleeve joint, which is sealed to the air inlet end of the inflatable airbag.

[0015] As a preferred embodiment, the first valve seat is provided with a snap-fit ​​groove, the movable end of the anti-leakage cover is provided with a toggle block, and a hook is provided on the anti-leakage cover and on the opposite side of the toggle block. When the air intake mechanism is in the closed state, the hook and the snap-fit ​​groove are snapped together.

[0016] As a preferred embodiment, a first one-way valve is installed inside the first valve seat. The first one-way valve includes a first base block, a connecting pipe is provided at one end of the first base block, and an airtight retaining ring is provided at the end of the connecting pipe.

[0017] The airtight retaining ring forms an annular fixing groove with the first base block, and the first valve seat is installed on the first valve seat using the annular fixing groove; when the anti-leakage cover is in the closed state, the anti-leakage cover and the airtight retaining ring are in close and airtight connection.

[0018] As a preferred embodiment, a first valve block is provided at the other end of the first one-way valve, and an air inlet opening and closing port is formed between the first valve block and the air inlet of the first base block.

[0019] When the inflatable airbag is under negative pressure, the air inlet is open; when the inflatable airbag is under compression, the air inlet is closed.

[0020] As a preferred embodiment, the air outlet mechanism includes a second fixed seat and a second valve seat. The second fixed seat is disposed on the inner side wall of the airtight cover, and the second valve seat is disposed on the outer side wall of the airtight cover; the second fixed seat and the second valve seat are connected together.

[0021] As a preferred embodiment, one end of the second valve seat is provided with a second airtight sleeve joint, which is sealed to the air outlet end of the inflatable airbag.

[0022] The second valve seat has an air outlet, and a second check valve is installed at the bottom of the second valve seat; the air outlet is connected to the second check valve.

[0023] As a preferred embodiment, the second one-way valve includes a second base block, a second valve block is provided at the lower end of the second base block, and an air outlet is formed between the second valve block and the second base block.

[0024] When the inflatable airbag is under negative pressure, the air outlet is closed; when the inflatable airbag is under compression, the air outlet is open.

[0025] As a preferred embodiment, the second fixing seat includes a fixing plate, which is disposed on the inner wall of the airtight cover. A sleeve is provided on the fixing plate, and an air guide is provided on the fixing plate, which is disposed corresponding to the sleeve. The second one-way valve is placed inside the sleeve.

[0026] As a preferred embodiment, the airtight cover is provided with a first mounting hole and a second mounting hole, the first fixing seat is connected to the first valve seat through the first mounting hole, and the fixing plate is connected to the second valve seat through the second mounting hole;

[0027] The airtight cover is also provided with a sleeve through hole, through which the sleeve passes.

[0028] Compared with the prior art, the present invention has the following advantages: the airtight bag body and the airtight bag lid are connected by an airtight zipper, ensuring the overall airtightness of the side bag. When the airtight bag body and the airtight bag lid are in a closed and sealed state, the side bag can be inflated by the inflation device at the top of the airtight bag lid. That is, when the inflation bladder is in a negative pressure state, external gas enters the inflation bladder through the air intake mechanism; when pressure is applied to the inflation bladder, the gas inside the inflation bladder enters the side bag through the air outlet mechanism; the user only needs to repeatedly squeeze the inflation bladder to inflate the side bag with air. The internal space is filled with air and pressure is generated. When the airbag is squeezed, the air inside the airbag enters the side bag through the air outlet mechanism. After the airbag is released, it returns to its original shape and forms a negative pressure state. At this time, outside air enters the airbag from the outside through the air inlet mechanism until the side bag is fully inflated and maintained. The inflated side bag can not only better protect the contents of the bag in the event of an accident involving a two-wheeled vehicle, but also provide a buffer space for the vehicle and passengers, increasing safety. In addition, the side bag is lightweight and easy to carry because it uses gas to support it. Attached Figure Description

Detailed Implementation

[0042] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0043] In this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "between," "one end," "the other end," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] like Figure 1-2As shown, the present invention provides a safety side bag for a two-wheeled vehicle, including an airtight body 1 and an airtight cover 2, which are sealed together by an airtight zipper 3. An inflation device 4 is provided on the top of the airtight cover 2. The inflation device 4 includes an airbag 41, an air intake mechanism 42, and an air outlet mechanism 43. The air intake mechanism 42 and the air outlet mechanism 43 are both fixedly installed on the airtight cover 2. The two ends of the airbag 41 are sealed to the air intake mechanism 42 and the air outlet mechanism 43, respectively. When the airbag 41 is in a negative pressure state, external gas enters the airbag 41 through the air intake mechanism 42. When pressure is applied to the airbag 41, the gas inside the airbag 41 enters the side bag through the air outlet mechanism 43. In this invention, the airtight bag body 1 and the airtight bag cover 2 are connected by an airtight zipper 3, ensuring the overall airtightness of the side bag. When the airtight bag body 1 and the airtight bag cover 2 are in a closed and sealed state, the side bag can be inflated by the inflation device 4 on the top of the airtight bag cover 2. That is, when the inflation bladder 41 is in a negative pressure state, external gas enters the inflation bladder 41 through the air intake mechanism 42; when pressure is applied to the inflation bladder 41, the gas inside the inflation bladder 41 enters the side bag through the air outlet mechanism 43; the user only needs to repeatedly squeeze the inflation bladder 41 to use air to inflate the inside of the side bag. When the space is filled and air pressure is generated, the air in the airbag 41 is squeezed and enters the side bag through the air outlet mechanism 43. After releasing, the airbag 41 returns to its original shape and forms a negative pressure state. At this time, outside air enters the airbag 41 from the outside through the air inlet mechanism 42 until the side bag is fully inflated and maintained. The inflated side bag can not only better protect the items inside the bag in the event of an accident involving a two-wheeled vehicle, but also provide a buffer space for the vehicle body and passengers, increasing safety. In addition, the side bag is lightweight and easy to carry because it uses gas to support it.

[0045] Reference Figure 4-8In some examples of the present invention, the air intake mechanism 42 includes a first fixed seat 421 and a first valve seat 422; the first fixed seat 421 is disposed on the inner side wall of the airtight cover 2, and the first valve seat 422 is disposed on the outer side wall of the airtight cover 2; the first fixed seat 421 and the first valve seat 422 are connected; one end of the first valve seat 422 is provided with a hinge groove 4221, a knurled shaft 4222 is disposed in the hinge groove 4221, and a leak-proof cover 423 is hinged on the knurled shaft 4222; The other end of the first valve seat 422 is provided with a first airtight sleeve connector 4223, which is sealed to the air inlet end of the inflatable airbag 41. With this solution, the knurled shaft 4222 is used to set the anti-leakage cover 423, so that when the side bag is full of gas, the anti-leakage cover 423 can be closed to prevent gas from overflowing and affecting the inflation state of the side bag. This further ensures that the side bag can not only better protect the contents of the bag in the event of an accident involving a two-wheeled vehicle, but also provide a buffer space for the vehicle body and passengers, thereby increasing safety.

[0046] Reference Figure 8 In a specific example of the present invention, the first valve seat 422 is provided with a snap-fit ​​groove 4224, and the movable end of the anti-leakage cover 423 is provided with a toggle block 4231. A hook 4232 is provided on the anti-leakage cover 423 and on the opposite side of the toggle block 4231. When the air intake mechanism 42 is in the closed state, the hook 4232 and the snap-fit ​​groove 4224 are snapped together. With this solution, since the anti-leakage cover 423 is hinged, when the air intake mechanism 42 leaks air, the anti-leakage cover 423 cannot play a sealing role under the action of air pressure. Therefore, by setting the hook 4232 and the snap-fit ​​groove 4224, the anti-leakage cover 423 can be tightly fastened to the first valve seat 422. When it is necessary to inflate the side bag, pressing the toggle block 4231 will disengage the hook 4232 and the snap-fit ​​groove 4224 to ensure that outside air can enter the inflatable airbag 41.

[0047] like Figure 7-9As shown in a specific example of the present invention, a first one-way valve 424 is installed inside the first valve seat 422. The first one-way valve 424 includes a first base block 4241. One end of the first base block 4241 is provided with a connecting pipe 4242, and the end of the connecting pipe 4242 is provided with an airtight retaining ring 4243. An annular fixing groove is formed between the airtight retaining ring 4243 and the first base block 4241. The first valve seat 422 is installed on the first valve seat 422 using the annular fixing groove. When the anti-leakage cover 423 is in the closed state, the anti-leakage cover 423 and the airtight retaining ring 4243 are fitted together and sealed. The other end of the first one-way valve 424 is provided with a first valve block 4244, and the first valve block 4244 and the first base block 4241 are connected together. An air inlet opening / closing port 4245 is formed between the air inlets. When the inflatable airbag 41 is under negative pressure, the air inlet opening / closing port 4245 is open. When the inflatable airbag 41 is under compression, the air inlet opening / closing port 4245 is closed. With this scheme, when the inflatable airbag 41 is under negative pressure, since outside air needs to enter the inflatable airbag 41, the first valve block 4244 is pushed inward under the action of airflow, so that the air inlet opening / closing port 4245 opens and gas enters the inflatable airbag 41. When the inflatable airbag 41 is compressed, the first valve block 4244 is pushed outward, so that the first valve block 4244 and the first base block 4241 fit together and close the air inlet opening / closing port 4245. At this time, gas cannot go out from the air intake mechanism 42, forming a one-way gas switch.

[0048] Reference Figure 10-11In a specific example of the present invention, the air outlet mechanism 43 includes a second fixed seat 431 and a second valve seat 432. The second fixed seat 431 is disposed on the inner side wall of the airtight cover 2, and the second valve seat 432 is disposed on the outer side wall of the airtight cover 2. The second fixed seat 431 and the second valve seat 432 are connected. One end of the second valve seat 432 is provided with a second airtight connector 4321, which is sealed to the air outlet end of the inflatable airbag 41. An air outlet 4322 is provided on the second valve seat 432, and a second one-way valve 433 is installed at the bottom of the second valve seat 432. The air outlet 4322 is connected to the second one-way valve 433. The second one-way valve 433 includes a second base block 4331. A second valve block 4332 is provided at the lower end of the base block 4331, and an air outlet 4333 is formed between the second valve block 4332 and the second base block 4331. When the inflatable airbag 41 is in a negative pressure state, the air outlet 4333 is in a closed state, and when the inflatable airbag 41 is in a compressed state, the air outlet 4333 is in an open state. With this scheme, when the inflatable airbag 41 is in a negative pressure state, the second valve block 4332 is in contact with the second base block 4331 under the action of gas and closes the air outlet 4333. When the inflatable airbag 41 is compressed, the air pressure of the inflatable airbag 41 increases, causing the second valve block 4332 to be pushed downward, and the air outlet 4333 is opened. At this time, the gas in the inflatable airbag 41 enters the side bag, forming a one-way gas switch.

[0049] like Figure 12 As shown, in a specific example of the present invention, the second fixing base 431 includes a fixing plate 4311, which is disposed on the inner wall of the airtight cover 2. A sleeve 4312 is disposed on the fixing plate 4311, and an air guide 4313 is opened on the fixing plate 4311. The air guide 4313 is disposed corresponding to the sleeve 4312. The second one-way valve 433 is placed inside the sleeve 4312. By adopting this scheme, by setting the sleeve 4312, the second one-way valve 433 is completely wrapped, avoiding gas leakage. At the same time, the air guide 4313 is opened to ensure that the gas can smoothly enter the side bag, improving the overall airtightness and thus improving the efficiency of inflation.

[0050] Reference Figure 1-3In some examples of the present invention, the airtight cover 2 is provided with a first mounting hole 201 and a second mounting hole 202. The first fixing seat 421 and the first valve seat 422 are connected through the first mounting hole 201, and the fixing plate 4311 and the second valve seat 432 are connected through the second mounting hole 202. The airtight cover 2 is also provided with a sleeve through hole 203, and the sleeve 4312 is provided through the sleeve through hole 203. By adopting this scheme, by setting the mounting hole and the sleeve through hole 203, after the first fixing seat 421 and the first valve seat 422, and the fixing plate 4311 and the second valve seat 432 are connected and clamped, gas is prevented from overflowing along the hole, which would cause the side bag to fail to protect the contents of the bag due to insufficient air pressure.
