Description

Technical Field

[0001] The utility model relates to an anti-rollover system, in particular to an anti-rollover system for the chassis of a low-speed sightseeing vehicle. Background Art

[0002] When a low-speed sightseeing vehicle makes a large turn, it is prone to skidding or rollover. At present, vehicles usually adopt ESP, that is, Electronic Stability Program, which integrates three systems: ABS (Anti-lock Braking System), BAS (Brake Assist System), and ASR (Acceleration Slip Regulation). By analyzing the vehicle driving state information transmitted by sensors, correction instructions are sent to ABS and ASR to help the vehicle maintain dynamic balance, especially in the case of oversteering or understeering, the effect is more obvious. However, the ESP system has a complex structure and high production cost, and is suitable for high-speed and high-production-cost automobiles, but not for sightseeing vehicles with low speed and low production cost requirements. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model proposes an anti-rollover system for the chassis of a low-speed sightseeing vehicle, which has a simple structure, low cost, and convenient operation, and is especially suitable for low-speed sightseeing vehicles.

[0004] To achieve the above technical solution, the utility model provides an anti-rollover system for the chassis of a low-speed sightseeing vehicle, including: two main beams arranged in parallel at intervals, two strip-shaped slide rails arranged in parallel and at intervals are installed between the two main beams, a counterweight plate is installed on the strip-shaped slide rails, a driving motor mounting plate is installed on the inner side surface of one of the main beams, a driving motor is fixed on the driving motor mounting plate, a driving shaft is installed on the output shaft of the driving motor, the driving shaft is connected to the bottom of the counterweight plate, and the driving motor drives the counterweight plate to move left and right along the strip-shaped slide rail through the driving shaft.

[0005] In the above technical solution, during actual use, only need to fix the main beam in the anti-rollover system for the chassis on the chassis of the low-speed sightseeing vehicle, and connect the driving motor to the steering system in the vehicle system. When turning left, the vehicle's center of gravity shifts to the left, and the steering system sends a signal of the center of gravity shift. The driving motor drives the counterweight plate to move to the right on the strip-shaped slide rail through the driving shaft, so that the vehicle's center of gravity shifts to the right, thereby preventing the vehicle from rolling over; when turning right, the vehicle's center of gravity shifts to the right, and the steering system sends a signal of the center of gravity shift. The driving motor drives the counterweight plate to move to the left on the strip-shaped slide rail through the driving shaft, so that the vehicle's center of gravity shifts to the left, preventing the vehicle from rolling over.

[0006] Preferably, the driving shaft is a lead screw, and the lead screw is connected to the bottom of the counterweight plate through a lead screw pair. During actual work, the precise adjustment of the position of the counterweight plate can be realized through the cooperation between the lead screw and the lead screw pair.

[0007] Preferably, one end of the lead screw is connected to the output shaft of the driving motor, and the other end of the lead screw is fixed on the inner side of the main beam. During actual operation, the driving motor drives the lead screw to rotate. Through the forward or reverse rotation of the lead screw, the counterweight plate is driven to move left and right on the strip-shaped slide rail.

[0008] Preferably, the mass of the counterweight plate is 5% of the total vehicle mass. Practical research shows that the mass of the counterweight plate cannot be too heavy, otherwise it will increase the total vehicle mass and energy consumption; the mass of the counterweight plate cannot be too light either, otherwise it will not be able to adjust the vehicle's center of gravity. When the mass of the counterweight plate is 5% of the total vehicle mass, it can achieve a good effect of adjusting the vehicle's center of gravity without significantly increasing the total vehicle mass.

[0009] The beneficial effects of the anti-rollover system for the chassis of a low-speed sightseeing vehicle provided by the present utility model are as follows: The anti-rollover system for the chassis of this low-speed sightseeing vehicle has a simple structure, reasonable design, easy installation, reliable use, and low cost. By adding this system to the chassis, the center-of-gravity offset during vehicle steering can be adjusted, and the possibility of rollover during vehicle turning can be reduced by the center-of-gravity offset. During actual use, only need to fix the main beam in the anti-rollover system of this chassis on the chassis of the low-speed sightseeing vehicle, and connect the driving motor to the steering system in the vehicle system. When turning left, the vehicle's center of gravity shifts to the left, and the steering system sends a signal of center-of-gravity offset. The driving motor drives the counterweight plate to move to the right on the strip-shaped slide rail through the drive shaft, so that the vehicle's center of gravity shifts to the right, thereby preventing the vehicle from rolling over; when turning right, the vehicle's center of gravity shifts to the right, and the steering system sends a signal of center-of-gravity offset. The driving motor drives the counterweight plate to move to the left on the strip-shaped slide rail through the drive shaft, so that the vehicle's center of gravity shifts to the left, preventing the vehicle from rolling over.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] Embodiment: A chassis anti-rollover system for a low-speed sightseeing vehicle.

[0015] As shown in Figures 1 to 2 , a chassis anti-rollover system for a low-speed sightseeing vehicle includes: two main beams 1 arranged in parallel at intervals. The two main beams 1 are respectively installed on the chassis of the low-speed sightseeing vehicle. Two strip-shaped slide rails 5 arranged in parallel at intervals are installed between the two main beams 1. A counterweight plate 6 is installed on the strip-shaped slide rails 5. The strip-shaped slide rails 5 play a role in guiding the stable movement of the counterweight plate 6. A drive motor mounting plate 2 is installed on the inner side surface of one of the main beams 1. A drive motor 3 is fixed on the drive motor mounting plate 2. A drive shaft 4 is installed on the output shaft of the drive motor 3. The drive shaft 4 is connected to the bottom of the counterweight plate 5. During actual operation, the drive motor 3 drives the counterweight plate 6 to move left and right along the strip-shaped slide rails 5 through the drive shaft 4. In this embodiment, the drive shaft 4 is a lead screw. The lead screw is connected to the bottom of the counterweight plate 6 through a lead screw pair. One end of the lead screw is connected to the output shaft of the drive motor 3, and the other end of the lead screw is fixed on the inner side surface of the main beam 1. During actual operation, the drive motor 3 drives the lead screw to rotate, and the precise adjustment of the position of the counterweight plate 6 can be achieved through the cooperation between the lead screw and the lead screw pair. When the lead screw rotates forward or backward, it drives the counterweight plate 6 to move left and right on the strip-shaped slide rails 5, and then the center of gravity of the chassis can be adjusted through the movement of the counterweight plate 6.

[0016] In this embodiment, the mass of the counterweight plate 6 is 5% of the total vehicle mass. Practical research shows that the mass of the counterweight plate 6 cannot be too heavy, otherwise it will increase the total vehicle mass and energy consumption; the mass of the counterweight plate 6 cannot be too light either, otherwise it will not play a role in adjusting the vehicle's center of gravity. When the mass of the counterweight plate 6 is 5% of the total vehicle mass, it can achieve a good effect of adjusting the vehicle's center of gravity without significantly increasing the total vehicle mass.

[0017] The chassis anti-rollover system of this low-speed sightseeing vehicle has a simple structure, reasonable design, easy installation, reliable use, and low cost. By adding this system to the chassis, the center-of-gravity offset during vehicle steering can be adjusted, and the possibility of vehicle rollover during turning can be reduced through the center-of-gravity offset. During actual use, only need to fix the main beam 1 in the chassis anti-rollover system of this system on the chassis of the low-speed sightseeing vehicle, and connect the drive motor 3 to the steering system in the vehicle system. When turning left, the vehicle's center of gravity shifts to the left, and the steering system sends a signal of center-of-gravity offset. The drive motor 3 drives the counterweight plate 6 to move to the right on the strip-shaped slide rails 5 through the drive shaft 4, so that the vehicle's center of gravity shifts to the right, thereby preventing the vehicle from rolling over; when turning right, the vehicle's center of gravity shifts to the right, and the steering system sends a signal of center-of-gravity offset. The drive motor 3 drives the counterweight plate 6 to move to the left on the strip-shaped slide rails 5 through the drive shaft 4, so that the vehicle's center of gravity shifts to the left, preventing the vehicle from rolling over, thus realizing the reduction of the possibility of vehicle rollover during turning through the center-of-gravity offset.
