Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a safety airbag device integrated into a bicycle frame. Background Technology

[0002] Cyclists face numerous potential dangers while riding a bicycle. Currently, most safety measures for cycling focus on the head and hands, lacking effective protection specifically for the groin area, which is extremely vulnerable. This is especially true since most bicycles have a high crossbar that is close to the rider's groin. In the event of a collision, the rider's forward momentum causes their groin to collide with the bicycle's crossbar, resulting in serious injury. Summary of the Invention

[0003] The purpose of this invention is to provide a safety airbag device integrated into a bicycle frame. An airbag module is installed at the crossbeam of the bicycle. In the event of an accident, the airbag module will deploy to protect the rider's groin, thereby solving the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a safety airbag device integrated in a bicycle frame, including a crossbeam, the side of the crossbeam facing the bicycle handlebars is provided with a mounting groove, and a safety airbag module is placed in the mounting groove for protecting the rider's groin. The crossbeam is provided with two cover plates at the mounting groove. The cover plates are arc-shaped and the surfaces of the two cover plates are smoothly connected to the surface of the crossbeam for sealing and protecting the mounting groove. The cover plate has a fixing groove on the side facing the mounting groove. An installation strip is inserted into the fixing groove. Elastic pieces are fixedly connected to the openings on both sides of the fixing groove to facilitate the separation of the cover plate from the crossbeam. A snap-fit ​​connector is fixedly connected to the side of the installation strip facing the mounting groove to fix the cover plate and the crossbeam. The inner walls on both sides of the mounting groove are fixedly connected to fixing plates. The fixing plates are located near the opening of the mounting groove. The mounting groove has a telescopic groove on the side facing the fixing plates. A limit plate is slidably connected in the telescopic groove for limiting and fixing the snap-fit ​​connector.

[0005] Preferably, the arc-shaped plate composed of the two sealing plates has a thickness in the middle section that is less than the thickness at both ends, which is used to control the flight direction of the sealing plates.

[0006] Preferably, the elastic sheet is formed by stamping copper sheet and has an arc-shaped structure, which facilitates the elastic sheet to limit and fix the mounting strip.

[0007] Preferably, the end of the mounting strip facing the cover plate has a columnar structure, which facilitates the mounting strip to compress the elastic sheet and deform the elastic sheet, while the end facing the mounting groove has a rectangular structure.

[0008] Preferably, the side of the connector facing the fixing plate is arc-shaped, used for positioning and installing the connector and the fixing plate.

[0009] Preferably, a spring is provided between the limiting plate and the telescopic groove, and the side of the snap-fit ​​connector facing the side wall of the mounting groove is composed of a guide arc surface and a blocking surface. The blocking surface is closer to the cover plate than the guide arc surface. The guide arc surface is used to push the limiting plate open. The limiting plate and the blocking surface are snapped together to fix the cover plate and the crossbeam.

[0010] Preferably, a rubber strip is provided at the corner where the fixing plate and the side wall of the mounting groove are connected, to control the tight fit between the locking connector and the limiting plate.

[0011] Preferably, the front end of the crossbeam is provided with a front fork, and a collision sensor is provided at the front fork, and the collision sensor is electrically connected to the airbag module.

[0012] The beneficial effects of this invention are as follows: when the collision sensor detects a bicycle collision, the airbag module pops out from the mounting slot to protect the rider's groin area, preventing the groin from directly impacting the crossbeam; the thickness of the arc-shaped plate formed by the two cover plates is less in the middle than at both ends. This unique thickness design allows control of the flight direction of the cover plates when the airbag module deploys, ensuring they fly away along a preset trajectory and preventing injury to the rider's groin.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] See Figures 1-5 This invention provides an integrated airbag device within a bicycle frame, comprising a crossbeam 1. The crossbeam 1 has a mounting groove 6 on its side facing the bicycle handlebars, within which an airbag module 5 is placed for groin protection of the rider. A front fork 2 is located at the front end of the crossbeam 1, and a collision sensor 3 is installed at the front fork 2. The collision sensor 3 is electrically connected to the airbag module 5. The airbag module 5 uses a Hovding airbag with an internal battery. The collision sensor 3 is a 77970-TZR-S11, which uses an inertial mechanical switch structure to monitor changes in deceleration or acceleration during a collision in real time, converting the physical impact into an electrical signal, thereby deploying the airbag module 5 to protect the rider's groin.

[0021] The crossbeam 1 is equipped with two cover plates 4 at the mounting slot 6. The cover plates 4 have an arc-shaped structure, and the surfaces of the two cover plates 4 are smoothly connected to the surface of the crossbeam 1. This smooth connection not only ensures the integrity and aesthetics of the bicycle frame, but also effectively reduces the resistance caused by airflow and other factors during riding. At the same time, it provides good sealing protection for the mounting slot 6, preventing dust, rainwater and other foreign objects from entering the mounting slot 6 and affecting the normal performance of the airbag module 5.

[0022] The arc-shaped plate composed of two cover plates 4, with the thickness in the middle being less than that at both ends, is used to control the flight direction of the cover plates 4. This unique thickness design allows the cover plates 4 to fly towards the rider's thighs when the airbag deploys, avoiding injury to the rider's groin.

[0023] The cover plate 4 has a fixing groove 11 on its side facing the mounting groove 6. An mounting strip 14 is inserted into the fixing groove 11. Elastic pieces 12 are fixedly connected to the openings on both sides of the fixing groove 11 to facilitate the separation of the cover plate 4 from the crossbeam 1. A snap-fit ​​connector 13 is fixedly connected to the side end of the mounting strip 14 facing the mounting groove 6 to securely connect the cover plate 4 and the crossbeam 1. The elastic piece 12 is made of stamped copper sheet and has an arc-shaped structure to facilitate the limiting and fixing of the mounting strip 14. The end of the mounting strip 14 facing the cover plate 4 has a columnar structure. During installation or disassembly, the mounting strip 14 compresses the elastic piece 12, causing it to deform, thereby achieving the separation or connection of the cover plate 4 and the mounting strip 14. The end of the mounting strip 14 facing the mounting groove 6 has a rectangular structure, which better cooperates with the snap-fit ​​connector 13 to ensure the stability of the structure. When the airbag module 5 is activated, the airbag can push open the cover plate 4, and the mounting strip 14 can separate from the fixing groove 11, making the separation of the cover plate 4 and the mounting strip 14 smoother.

[0024] The side of the connector 13 facing the fixing plate 7 is curved, which allows for more accurate positioning and installation of the connector 13 and the fixing plate 7, enabling them to connect smoothly and improving the efficiency and accuracy of installation.

[0025] Fixing plates 7 are fixedly connected to the inner walls of both sides of the mounting groove 6. The fixing plates 7 are close to the opening of the mounting groove 6. The side of the mounting groove 6 facing the fixing plates 7 is provided with a telescopic groove 9. A limiting plate 10 is slidably connected in the telescopic groove 9 to limit and fix the snap-fit ​​connector 13. A spring is provided between the limiting plate 10 and the telescopic groove 9. The side of the snap-fit ​​connector 13 facing the side wall of the mounting groove 6 is composed of a guide arc surface 15 and a blocking surface 16. The blocking surface 16 is closer to the cover plate 4 than the guide arc surface 15. The guide arc surface 15 is used to push the limiting plate 10 open. The limiting plate 10 and the blocking surface 16 are interlocked to fix the cover plate 4 and the crossbeam 1. When the snap-fit ​​connector 13 is installed on the fixing plate 7, the guide arc surface 15 of the snap-fit ​​connector 13 presses against the limiting plate 10, thereby retracting the limiting plate 10 into the telescopic groove 9. At this time, the limiting plate 10 compresses and stores the spring. When the limiting plate 10 is located on the blocking surface 16, the spring controls the limiting plate 10 to pop out, and the limiting plate 10 limits and fixes the snap-fit ​​connector 13.

[0026] A rubber strip 8 is provided at the corner where the fixed plate 7 and the side wall of the mounting groove 6 are connected. This strip is used to control the tight fit between the clamping connector 13 and the limiting plate 10, further enhancing the firmness of the connection between the cover plate 4 and the crossbeam 1 and reducing loosening of the connection due to vibration or other reasons.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
