Description

Technical Field

[0001] The present invention relates to the technical field of scooters, and more specifically, it relates to a braking assistance system for elderly scooters. Background Art

[0002] Elderly scooters are ideal vehicles for the elderly to travel outdoors. They are also called senior cars, electric senior cars, and three- (or four-) wheeled senior cars. Their performance is relatively stable, the speed is slow, and they use electricity without refueling, so they are also called environmentally friendly senior cars.

[0003] Elderly scooters are particularly popular in rural areas because they provide a relatively safe way to travel, especially performing well in the tasks of picking up and dropping off children to and from school. However, since most elderly scooters cannot be licensed and insured, and the drivers often lack the necessary traffic safety training, there are relatively large safety hazards on the road. Especially in terms of the driving speed, although most elderly scooters are equipped with devices to limit the speed, the drivers still often cause traffic accidents due to relatively fast speeds during actual driving.

[0004] Therefore, a new solution is needed to solve this problem. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a braking assistance system for elderly scooters to solve the defects existing in the above background art.

[0021] An elderly people's scooter brake assist system, as Figures 1 - 12 shown, includes a mounting bracket 1 installed on the vehicle body. A plurality of sliding grooves 2 are opened at the front part of the vehicle body corresponding to the mounting bracket 1. A connecting rod 3 is slidably connected in the plurality of sliding grooves 2. A limiting groove 4 is opened on the side wall of the sliding groove 2. A limiting rod 5 is fixedly connected to the side wall of the connecting rod 3. The limiting rod 5 and the limiting groove 4 are connected by a first spring 6. A windshield 7 that shields the front part of the vehicle body is fixedly connected to the side of the connecting rod 3 away from the mounting bracket 1. A first pressure sensor 8 corresponding to the connecting rod 3 is installed in the sliding groove 2. A control component and an auxiliary brake component are arranged at the bottom of the vehicle body corresponding to the mounting bracket 1. The control component is connected to the first pressure sensor 8, and when the detection data of the first pressure sensor 8 exceeds a preset value, the control component drives the auxiliary brake component to start braking; Further, the control component includes an installation box 9 detachably connected to the mounting bracket 1. An oil cylinder 10 and a control panel 11 for controlling the operation of the oil cylinder 10 are fixedly connected inside the installation box 9. The control panel 11 is connected to the first pressure sensor 8. The output end of the oil cylinder 10 penetrates through the installation box 9 to the outside and is fixedly connected to a connecting plate 12. A plurality of connecting grooves 13 are formed at one end of the connecting plate 12 away from the oil cylinder 10. A moving rod 14 is slidably connected inside the connecting groove 13. One end of the moving rod 14 is connected to the bottom of the connecting groove 13 through a second spring 15. When the second spring 15 is in a natural state, the other end of the moving rod 14 protrudes from the notch of the connecting groove 13. When the value detected by the first 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 road surface. Since the moving rod 14 is connected to the bottom of the connecting groove 13 through the second spring 15 and the second spring 15 protrudes from the notch of the connecting groove 13 in the natural state, the moving rod 14 will first abut against the road surface and force the second spring 15 to contract. The acting force generated when the moving rod 14 abuts against the road surface is used to achieve a certain deceleration effect. When the value detected by the first pressure sensor 8 is less than the preset value, the control panel 11 drives the output end to retract and drives the connecting plate 12 to reset. The contracted second spring 15 returns to its original state and forces the connecting rod 3 to protrude from the notch of the connecting groove 13 again, facilitating subsequent use; Further, the auxiliary braking component includes a plurality of anti-slip plates 16 detachably connected to the bottom of the connecting plate 12 by bolts. A plurality of anti-slip blocks 17 are fixedly connected to the anti-slip plates 16. The anti-slip blocks 17 are tooth-shaped and are inclined toward the front side of the vehicle body. The anti-slip blocks 17 are made of aluminum alloy. When the oil cylinder 10 drives the connecting plate 12 to move up and down, the anti-slip plates 16 connected to the connecting plate 12 will move together. At the same time, the anti-slip blocks 17 on the anti-slip plates 16 will also move together until they abut against the road surface. The anti-slip blocks 17 and the road surface are used to rub against each other to achieve a deceleration effect. At the same time, since the anti-slip blocks 17 are tooth-shaped, the friction between the anti-slip blocks 17 and the road surface can be further increased, improving the deceleration effect. And the anti-slip blocks 17 are made of aluminum alloy, with a relatively soft texture, to avoid damaging the road surface; Further, it further includes an audible and visual alarm 18 installed on the top of the vehicle body. A groove 20 is formed in the connection groove 13. A connection block 21 that is slidably connected to the groove 20 is fixedly connected to the side wall of the moving rod 14. A touch switch 22 connected to the audible and visual alarm 18 is fixedly connected in the groove 20. When the second spring 15 is in a natural state, the connection block 21 is separated from the touch switch 22. When the connection block 21 abuts against the touch switch 22, the audible and visual alarm 18 emits an alarm. By the mutual cooperation between the connection block 21 and the groove 20, it is avoided that the position of the connecting rod 3 is offset when sliding in the connection groove 13. At the same time, through the mutual cooperation of the touch switch 22 and the audible and visual alarm 18, when the touch switch 22 abuts against the connection block 21, the audible and visual alarm 18 gives an alarm to remind pedestrians, thereby reminding pedestrians to avoid, and improving the safety during driving; Further, it further includes an elastic ring 23 sleeved on the steering wheel. A plurality of chambers 24 are formed in the elastic ring 23. A second pressure sensor 25 connected to the control panel 11 is arranged in the chambers 24. When the detected value of the second pressure sensor 25 is greater than a preset value, the control panel 11 drives the output end of the oil cylinder 10 to extend. When facing an emergency braking situation, the driver sometimes cannot step on the brake in time to decelerate. According to the natural reaction of the human body in an emergency, the hand will involuntarily clench, thereby applying a force to the second pressure sensor 25. When this force is greater than the preset value, the control panel 11 will drive the output end of the oil cylinder 10 to extend, so as to achieve the effect of braking and decelerating, leaving time for the driver to step on the brake to react; Further, a plurality of anti-slip grooves 26 are arranged on the surface of the elastic ring 23. The plurality of chambers 24 correspond to the anti-slip grooves 26 one by one. The arrangement of the anti-slip grooves 26 can, on the one hand, prevent the driver from slipping when turning the steering wheel, and on the other hand, can also ensure that the second pressure sensor 25 can accurately sense the force when the driver holds the steering wheel; Further, the first pressure sensor 8 and the second pressure sensor 25 are connected to the voice module and the display module of the in-vehicle central control screen. By using the setting of the central control screen, the driver is reminded visually and audibly, further improving safety; Further, auxiliary plates 27 are provided on both sides of the mounting bracket 1. A number of channels 28 are formed in the auxiliary plates 27. A number of connecting shafts 29 which are arranged in a staggered manner are fixedly connected in the channels 28. Rotating blocks 30 are rotatably connected to the connecting shafts 29. A cavity 31 is arranged in the rotating blocks 30. An active block 32 is arranged in the cavity 31. During the driving process of the vehicle, air will pass through the channels 28 on the auxiliary plates 27. The flowing air in the channels 28 will force the rotating blocks 30 to rotate along the connecting shafts 29. During the rotation of the connecting shafts 29, the active block 32 in the cavity 31 will impact the inner wall of the cavity 31 to generate sound, so as to remind pedestrians beside, thereby improving the safety during vehicle driving. And as the vehicle speed increases, the rotation frequency of the rotating blocks 30 will increase, thereby increasing the impact frequency of the active block 32, thus increasing the sound generated during the impact and further improving the safety; Further, moving grooves 33 are formed in the two sides of the mounting bracket 1 along its height direction. A moving block 34 is fixedly connected to the side wall of the auxiliary plate 27. A driving rod 19 is fixedly connected to the auxiliary plate 27. 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 arrangement of the moving grooves 33 can prevent the position of the auxiliary plate 27 from shifting during the movement; The present invention is used as follows: During the driving process of the vehicle, the windshield 7 will move towards the bottom side of the sliding groove 2 under the influence of wind force. Since the windshield 7 is fixedly connected to the connecting rod 3, the connecting rod 3 will also move towards the bottom side of the sliding groove 2 until the connecting rod 3 moves to abut against the pressure sensor I 8. At the same time, during the movement of the connecting rod 3, the limiting rod 5 connected to the connecting rod 3 will move together, thereby squeezing the first spring 6. When the value detected by the pressure sensor I 8 is greater than the preset value, the control component will drive the auxiliary brake component to start for deceleration, so as to limit the vehicle speed and reduce the potential safety hazard caused by the excessive vehicle speed during the driving process of the driver. When the vehicle stops, the contracted first spring 6 will gradually return to its original state and drive the connecting rod 3 and the windshield 7 to return to their original states, ensuring normal use during the next driving.

[0022] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
