Technical Field

[0001] The utility model relates to the technical field of rollover protection, in particular to a vehicle rollover protection device. Background Art

[0002] The purpose of installing a rollover protection device on a vehicle is to effectively reduce the damage to the vehicle and protect passengers from direct injury by providing additional structural strength and protective barriers in the event of a rollover accident, thereby improving driving safety and the chances of passenger survival.

[0003] In this regard, China has filed patent application number CN211032487U, which discloses a vehicle rollover occupant protection device, comprising a retractable protective net, a guide mechanism, a drive mechanism, a controller, and a speed sensor and an angle sensor; both of which are connected to the controller by signal. When a dangerous situation occurs, the speed sensor and angle sensor collect relevant information and transmit the collected information to the controller for comparison. If the vehicle is in a dangerous state, a command is sent to activate the drive mechanism, which rapidly deploys the retractable protective net and covers the windows, protecting the occupants from being thrown out of the vehicle and preventing secondary injuries. This device is highly practical.

[0004] In the process of implementing this application, the inventor discovered the following problems in this technology: although the vehicle rollover protection device in the above application can quickly deploy a retractable protective net through a driving mechanism to protect the occupants in the vehicle, it has deficiencies in impact force absorption and dispersion, stability of the protective frame, and durability and user experience of the device, resulting in an inability to fully protect the safety of the vehicle and passengers in serious rollover or collision accidents, reducing the overall protection effect and reliability of use. Utility Model Content

[0005] In order to solve the above problems, the present application provides a vehicle rollover protection device.

[0006] The present application provides an advertising design display device that adopts the following technical solutions:

[0008] A buffer assembly is provided on the protective frame and is used to buffer the protective frame when it is hit;

[0009] The shielding mechanism is arranged on the support frame and is used to shield the entire device.

[0010] By adopting the above technical solution, the vehicle rollover protection device realizes the rapid deployment and storage of the protection frame, utilizes the buffer component to effectively absorb the collision impact, and at the same time protects the device from rain and sun through the shielding mechanism, thereby improving the overall safety of vehicle driving and the practicality of the device.

[0011] As a further improvement of this solution, the buffer assembly includes cavities opened on both sides of the bottom of the protective frame, and a sleeve is fixedly provided inside the two cavities, a seat is slidingly provided on the outside of the sleeve, and a buffer spring is provided inside the sleeve and the seat, one end of the buffer spring is fixedly connected to the inner wall of the seat, and the other end of the buffer spring is fixedly connected to the inner wall of the cavity, and a damper is fixedly provided on the inner wall of the seat and the inner ring of the buffer spring, and the piston end of the damper is fixedly connected to the inner wall of the cavity.

At the same time, the design of the connecting block enables the shielding cloth to be firmly fixed on the cover frame, enhancing the overall durability and practicality.

[0015] As a further feature of this solution, a rubber pad is fixedly provided on one side of each of the four stops, and an anti-slip stripe is provided on one side of the rubber pad.

[0021] As a further feature of this solution, a protective net is fixedly provided on the inner side of the protective frame, and the protective net is made of metal.

[0022] By adopting the above technical solution, the metal protective net not only enhances the strength and durability of the protective frame, effectively resists the impact force during rollover or collision, and protects the safety of the vehicle and passengers, but also further improves the overall protective effect of the protective frame, providing more solid and reliable rollover protection for vehicle driving.

[0045] Reference Figure 2 , one end of the two rotating rods 3 is fixed with a rotating shaft 17, the two rotating shafts 17 pass through and rotate on one side of the support frame 2 and extend to the outside, the outside of the two rotating shafts 17 is fixed with a driven synchronous wheel 18, the bottom wall of the support frame 2 is fixed with a motor 19, and one end of the output shaft of the motor 19 is fixed with a driving synchronous wheel 20, the two driven synchronous wheels 18 and the driving synchronous wheel 20 are externally driven with a synchronous belt 21, and the cover frame 10 is covered on the outside of the driven synchronous wheel 18, the driving synchronous wheel 20 and the synchronous belt 21.

[0048] The above technical solution can achieve the goal that the metal protective net 401 not only enhances the strength and durability of the protective frame 4, effectively resists the impact force during rollover or collision, and protects the safety of the vehicle and passengers, but also further improves the overall protective effect of the protective frame 4, providing more solid and reliable rollover protection for vehicle driving.

[0049] However, as is well known to those skilled in the art, the working principle and wiring method of the motor 19 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience, connect them to the controller through lines, and supply energy through an external power supply.

[0050] The working principle and use process of this technical solution are as follows: when the vehicle needs rollover protection, the motor 19 is started, and the output shaft of the motor 19 drives the active synchronous wheel 20 to rotate. While the active synchronous wheel 20 rotates, it drives the two driven synchronous wheels 18 and the rotating shaft 17 thereon to rotate synchronously through the synchronous belt 21. While the two rotating shafts 17 rotate, they drive the rotating rod 3 and the protective frame 4 to unfold to the predetermined position (the final position of the protective frame 4 is shown in FIG). Figure 1 As shown), forming protection for the side of the vehicle;

[0051] When the vehicle rolls over or collides, the protective frame 4 first bears the impact force, the stopper 6 slides in the sleeve 5, and the buffer spring 8 is compressed and absorbs part of the impact energy. The damper 7 further slows down the movement speed of the stopper 6, protecting the vehicle body 1 while also reducing the impact of the protective frame 4 on the vehicle body 1;

[0052] When rollover protection is no longer needed, start the motor 19. The motor 19 reverses and drives the two protective frames 4 to rotate to the roof and locate inside the two support frames 2 through the above principle. Then manually pull the hook 15. When the hook 15 is pulled, it drives the connecting block 14 to disengage from the top of the cover frame 10. When the connecting block 14 disengages, it drives the shielding cloth 13 to rotate and unfold from the cross bar 11. At this time, the clockwork spring 12 is forced to shrink the potential energy, and then continues to pull the hook 15 to cover the shielding cloth 13 on the top of the two support frames 2 and the two protective frames 4 to block them. Then the hook 15 is hooked on the hanging ring 16 to complete the fixing of the shielding cloth 13. When rollover protection is needed, just remove the hook 15 from the hanging ring 16, and then the stressed clockwork spring 12 releases the potential energy, driving the cross bar 11 to rotate in the opposite direction, so that the cross bar 11 winds up the shielding cloth 13, thereby storing the shielding cloth 13 in the cover frame 10.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
