They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0032] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0033] A brake assist system for an elderly scooter, such as Figures 1-12As shown, it includes a mounting frame 1 installed on the vehicle body, and the mounting frame 1 is provided with a plurality of sliding grooves 2 at the front portion corresponding to the vehicle body, and connecting rods 3 are slidably connected in the plurality of sliding grooves 2, and a limiting groove 4 is provided on the side wall of the sliding groove 2, and a limiting rod 5 is fixedly connected to the side wall of the connecting rod 3, and the limiting rod 5 and the limiting groove 4 are connected by a spring 6, and a windshield 7 that blocks the front portion of the vehicle body is fixedly connected to the side of the connecting rod 3 away from the mounting frame 1, and a pressure sensor 8 corresponding to the connecting rod 3 is installed in the sliding groove 2, and a control component and an auxiliary brake component are provided at the bottom portion of the mounting frame 1 corresponding to the vehicle body, and the control component is connected to the pressure sensor 8, and when the detection data of the pressure sensor 8 exceeds the preset value, the control component drives the auxiliary brake component to start braking;

[0034] Furthermore, the control component includes a mounting box 9 detachably connected to the mounting frame 1, a cylinder 10 and a control panel 11 for controlling the operation of the cylinder 10 are fixedly connected to the mounting box 9, the control panel 11 is connected to the pressure sensor 8, the output end of the cylinder 10 passes through the mounting box 9 to the outside and is fixedly connected to a connecting plate 12, a plurality of connecting grooves 13 are provided on the end of the connecting plate 12 away from the cylinder 10, a moving rod 14 is slidably connected in the connecting groove 13, one end of the moving rod 14 is connected to the bottom of the connecting groove 13 through a spring 2 15, and when the spring 2 15 is in a natural state, the other end of the moving rod 14 protrudes from the notch of the connecting groove 13, and when the value detected by the pressure sensor 8 is greater than the preset value , the control panel 11 will drive the output end of the oil cylinder 10 to extend, thereby driving the connecting plate 12 to move toward the side of the road surface. Since the moving rod 14 is connected to the bottom of the connecting groove 13 through the spring 2 15, and the spring 2 15 naturally protrudes from the notch of the connecting groove 13, the moving rod 14 will first contact the road surface and force the spring 2 15 to contract. The force generated when the moving rod 14 contacts the road surface has a certain deceleration effect. When the value detected by the pressure sensor 18 is less than the preset value, the control panel 11 drives the output end to retract and drive the connecting plate 12 to reset. The contracted spring 2 15 returns to its original state and forces the connecting rod 3 to protrude from the notch of the connecting groove 13 again, which is convenient for subsequent use;

[0035] Furthermore, the auxiliary brake assembly includes a plurality of anti-skid plates 16 detachably connected to the bottom of the connecting plate 12 by bolts, and a plurality of anti-skid plates 17 are fixedly connected to the anti-skid plates 16. The anti-skid plates 17 are tooth-shaped and tilted toward the front side of the vehicle body. The anti-skid plates 17 are made of aluminum alloy. When the oil cylinder 10 drives the connecting plate 12 to move up and down, the anti-skid plates 16 connected to the connecting plate 12 will move together with it. At the same time, the anti-skid plates 17 on the anti-skid plates 16 will also move together with it until they are against the road surface. The friction between the anti-skid plates 17 and the road surface is used to achieve a deceleration effect. At the same time, since the anti-skid plates 17 are tooth-shaped, the friction between the anti-skid plates 17 and the road surface can be further increased, thereby improving the deceleration effect. In addition, the anti-skid plates 17 are made of aluminum alloy, which is soft in texture and avoids damaging the road surface.

[0036] Furthermore, the vehicle body further includes an audible and visual alarm 18 installed on the top of the vehicle body, a groove 20 is provided in the connecting groove 13, a connecting block 21 slidably connected to the groove 20 is fixedly connected to the side wall of the movable rod 14, a touch switch 22 connected to the audible and visual alarm 18 is fixedly connected in the groove 20, when the spring 2 15 is in the natural state, the connecting block 21 is separated from the touch switch 22, and when the connecting block 21 and the touch switch 22 abut against each other, the audible and visual alarm 18 sounds an alarm, and the mutual cooperation between the connecting block 21 and the groove 20 prevents the position of the connecting rod 3 from being offset when it slides in the connecting groove 13. At the same time, through the mutual cooperation between the touch switch 22 and the audible and visual alarm 18, when the touch switch 22 abuts against the connecting block 21, the audible and visual alarm 18 sounds an alarm to remind pedestrians, and then reminds pedestrians to avoid, thereby improving driving safety;

[0037] Furthermore, the steering wheel further includes an elastic ring 23 mounted on the steering wheel. The elastic ring 23 defines a plurality of chambers 24. The chambers 24 contain a second pressure sensor 25 connected to the control panel 11. When the value detected by the second pressure sensor 25 is greater than a preset value, the control panel 11 causes the output end of the oil cylinder 10 to extend. When faced with a situation requiring emergency braking, the driver may not be able to brake and slow down in time. According to the human body's natural reaction in an emergency, the hands will involuntarily clench, thereby applying a force to the second pressure sensor 25. When the force exceeds the preset value, the control panel 11 causes the output end of the oil cylinder 10 to extend, thereby achieving the braking and deceleration effect, giving the driver time to react to braking.

[0038] Furthermore, the surface of the elastic ring 23 is provided with a plurality of anti-skid grooves 26, and the plurality of chambers 24 correspond one-to-one with the anti-skid grooves 26. The provision of the anti-skid grooves 26 prevents the driver from slipping when turning the steering wheel, and also ensures that the pressure sensor 25 can accurately sense the force exerted by the driver when gripping the steering wheel.

[0039] Furthermore, the pressure sensor 1 8 and the pressure sensor 2 25 are connected to the voice module and display module of the central control screen in the vehicle body, and the setting of the central control screen is used to remind the driver through vision and hearing, thereby further improving safety;

[0040] Furthermore, auxiliary plates 27 are provided on both sides of the mounting frame 1. A plurality of channels 28 are formed on the auxiliary plates 27. A plurality of connecting shafts 29 arranged in an interlaced manner are fixedly connected in the channels 28. A rotating block 30 is rotatably connected to the connecting shaft 29. A cavity 31 is provided in the rotating block 30. A movable block 32 is provided in the cavity 31. During the driving of the vehicle, air will pass through the channels 28 on the auxiliary plates 27. The air flow in the channels 28 will force the rotating block 30 to rotate along the connecting shaft 29. During the rotation of the connecting shaft 29, the movable block 32 in the cavity 31 will hit the inner wall of the cavity 31, thereby making a sound, thereby alerting pedestrians on the side, thereby improving the safety of the vehicle during driving. In addition, as the vehicle speed increases, the rotation frequency of the rotating block 30 will increase, thereby increasing the impact frequency of the movable block 32, thereby increasing the sound produced during the impact, thereby further improving safety.

[0041] Furthermore, movable grooves 33 are provided on both sides of the mounting frame 1 along its own height direction, and movable blocks 34 are fixedly connected to the side walls of the auxiliary plate 27. A driving rod 19 is fixedly connected to the auxiliary plate 27, and the driving rod 19 is fixedly connected to the side wall of the connecting plate 12. When the connecting plate 12 moves up and down, the driving rod 19 can drive the auxiliary plate 27 to move together. At the same time, the provision of the movable grooves 33 can prevent the position of the auxiliary plate 27 from being offset during the movement process.

[0042] The present invention is used as follows:

[0043] When the vehicle is driving, the windshield 7 will be affected by the wind and move toward the bottom of the sliding groove 2. Since the windshield 7 is fixedly connected to the connecting rod 3, the connecting rod 3 will also move toward the bottom of the sliding groove 2 until the connecting rod 3 moves to abut against the pressure sensor 8. At the same time, during the movement of the connecting rod 3, the limit rod 5 connected to the connecting rod 3 will move together, thereby squeezing the spring 6. When the value detected by the pressure sensor 8 is greater than the preset value, the control component will drive the auxiliary brake component to start and slow down, so as to limit the vehicle speed and reduce the safety hazards caused by the driver's excessive speed during driving. When the vehicle stops, the contracted spring 6 will gradually return to its original state and drive the connecting rod 3 and the windshield 7 to return to their original state, ensuring normal use during the next driving.

[0044] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
