Description

Technical Field

[0001] The invention relates to the field of vehicle equipment, and in particular to a vehicle rollover structure. Background Art

[0002] When a tricycle turns, due to the effects of gravity and centrifugal force, the center of gravity of the vehicle will shift to the outside of the curve, causing the vehicle to tilt. This is because the wheel on the outside of the curve is subjected to excessive force, while the force on the inner wheel is relatively small. The outer wheel may fit more closely to the ground due to excessive pressure, while the inner wheel may slightly lift up due to less force, causing uneven tire wear, especially more severe wear on the wheel on the outside of the curve. If the inner wheel lifts up severely and loses grip, the motorcycle may lose stability and suffer serious accidents such as rollover. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a vehicle roll structure for solving the technical problem in the prior art that when a vehicle turns, the vehicle tilts, causing the outer wheels to be subjected to greater pressure and the inner wheels to tilt.

[0010] When the vehicle turns, the centrifugal force generated by the turning of the vehicle causes the wheel on one side to rise, squeezing the corresponding shock absorber to rotate the rotating bracket, forcing the wheel on the other side to lower.

[0011] Optionally, the connecting member is connected to the frame via a ball joint.

[0012] Optionally, the connecting member and the fixing bracket are connected via a ball joint.

The change or adjustment of the relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0040] See also Figures 1 to 6 As shown, the present invention provides a vehicle roll structure, comprising:

[0041] A frame 1, wherein the left and right sides of the frame 1 are respectively provided with mounting parts;

[0042] Two wheels 2, each of the two wheels 2 is connected to the mounting portion via a fixing bracket 201, the fixing bracket is hinged to the mounting portion, and the fixing bracket is arranged in a horizontal direction relative to the rotation axis of the mounting portion;

[0043] A rotating bracket 3 is provided on the frame 1, and the middle part of the rotating bracket 3 is hinged to the frame 1. The two ends of the wheel 3 are respectively connected to the fixed bracket 201 through a connecting member 4, and the connection point between the connecting member and the fixed bracket 201 is far away from the hinge point between the fixed bracket 201 and the mounting portion.

[0044] It should also be noted that the frame 1 includes a left frame and a right frame, and a bottom plate is provided between the left frame and the right frame. The bottom plate is used to install a power motor, and the power motor provides power to the wheels 2.

[0045] Furthermore, the left frame, the right frame and the bottom plate are integrally formed.

[0046] When the vehicle of the present application turns, the center of gravity of the vehicle shifts to the inside of the curve, and the wheel on the inside of the curve is subjected to pressure and rotates relative to the frame 1. During the rotation of the inner wheel 2, the connecting member 4 pushes the rotating bracket 3 to rotate. During the rotation of the rotating bracket 3, the rotating bracket 3 pushes the other wheel 2 to move horizontally relative to each other, and the component force of gravity is used to dynamically balance the centrifugal force generated during the turn.

[0047] Exemplarily, the connecting member 4 includes a frame connecting portion and a wheel connecting portion, the frame connecting portion is connected to the corresponding end of the rotating bracket 3, the wheel connecting portion is connected to the corresponding fixed bracket 201, and the frame connecting portion and the wheel connecting portion are connected through a shock absorber;

[0048] When the vehicle turns, the centrifugal force generated by the vehicle turns causes the wheel 2 on one side to be lifted, squeezing the corresponding shock absorber to rotate the rotating bracket, forcing the wheel on the other side to be lowered, causing the vehicle to tilt, and using the gravity component of the vehicle to dynamically balance the centrifugal force generated when turning.

[0049] It should also be noted that the purpose of setting up shock absorbers is that when the vehicle passes over uneven roads, the shock absorber's shock absorbing spring can absorb the energy caused by the bumps, reduce the violent shaking of the vehicle body, quickly absorb the vibration, allow the vehicle to return to normal driving state as soon as possible, and effectively reduce the impact of the impact on the vehicle and passengers.

[0050] It should also be noted that the shock absorber in the present application also includes a piston rod and a cylinder. The purpose is that when the wheel 2 on the inner side of the curve is compressed and pushes the corresponding connecting part 4, the piston rod and the cylinder can guide the contraction direction of the connecting part 4. When the vehicle encounters bumps, the piston rod can respond quickly and absorb and disperse the impact force through its own telescopic movement.

[0051] Exemplarily, the connecting member 4 is connected to the vehicle frame 1 via a ball joint.

[0052] It should also be noted that the ball joint connection method is adopted so that the connecting member 4 can be adjusted along with the positions of the two ends of the rotating bracket 3 during the rotation of the rotating bracket 3, thereby avoiding mechanical damage between the connecting member 4 and the frame 1 due to the change in the position of the wheel 2.

[0053] Exemplarily, the connecting member 4 is connected to the fixing bracket 201 via a ball joint.

[0054] It should also be noted that the ball joint between the connecting member 4 and the fixed bracket 201 can ensure that when the connecting member 4 is offset during the rotation of the rotating bracket 3, it will not affect the hinge between the connecting member 4 and the fixed bracket 201.

[0055] Exemplarily, two power motors are further provided on the vehicle frame 1 , and the power motors drive the corresponding wheels 2 respectively.

[0056] It should also be noted that the present application arranges two power motors on the frame 1, and the power motors are arranged on the bottom plate of the frame, so that one power motor can drive one wheel 2, so that the two wheels 2 can run at different speeds, and the dual-motor drive system can independently control the speed and torque of each wheel, so as to more accurately adjust the driving posture of the vehicle. Under complex road conditions, such as turning or driving on uneven roads, the dual-motor drive system can better maintain the stability and controllability of the vehicle. According to the driving conditions of the vehicle and the needs of the driver, the dual-motor drive system can dynamically adjust the output power and torque distribution of each motor. This dynamic adjustment helps to reduce energy loss, improve energy utilization efficiency, and thus extend the vehicle's cruising range.

[0057] Exemplarily, the center lines of the rotation axes of the two fixed brackets 201 are arranged colinearly with the center lines of the output shafts of the two power motors.

[0058] It should also be noted that in the present application, the center lines of the rotating axes of the two fixed brackets 201 are colinearly arranged with the center lines of the output shafts of the two power motors. When the wheel 2 rotates relative to the frame 1, the distance between the wheel 2 and the power motor on the frame 1 will not change, and the transmission distance between the power motor and the corresponding wheel 2 will not be affected, and the transmission failure problem caused by the rotation of the wheel 2 will not occur.

[0059] Exemplarily, the frame 1 is provided with a brake 5, and the brake 5 is used to lock the rotation angle of the rotating bracket 3, thereby locking the lifting of the wheel.

[0060] It should also be noted that the purpose of providing the brake 5 is to lock the rotation angle of the rotating bracket 3 so that the vehicle can turn off the lifting function of the wheel 2 or keep the wheel 2 in a state of height difference.

[0061] Exemplarily, a hub motor is provided at the connection between the fixed bracket and the wheel, and the hub motor drives the corresponding wheels respectively. This solution does not need to provide a power motor on the frame 1, further simplifying the vehicle structure.

[0064] It should also be noted that, in the present application, the fixed plate 501 and the movable plate 502 are both movably mounted on the plurality of guide rods, and the guide rods are used to guide the movable directions of the fixed plate 501 and the movable plate 502, and the driving unit 505 is used to make the fixed plate 501 and the movable plate 502 close to each other to complete the locking, and the elastic unit 6 can use the elasticity to drive the fixed plate 501 and the movable plate 502 away from each other when the driving unit 505 is not working.

[0065] Exemplarily, a mounting bracket is provided on the mounting seat, and the mounting bracket is installed on the mounting seat, and both ends of the guide rod are respectively arranged on the mounting seat and the mounting bracket, and a clamping area is provided between the mounting bracket and the mounting seat, the fixed plate and the movable plate are located in the clamping area, and the driving unit 505 is arranged on the mounting bracket.

[0066] It should also be noted that the purpose of providing the mounting bracket is to provide a mounting position for the drive unit 505 and to limit the movable range of the fixed plate 501 and the movable plate 502 .

[0067] Exemplarily, the elastic unit 6 is a spring sheet with a V-shaped structure, the elastic unit 6 is arranged on the mounting seat, one end of the elastic unit 6 abuts against the fixed plate, and the other end of the elastic unit 6 abuts against the movable plate.

[0068] It should also be noted that the elastic unit 6 is made of beryllium copper alloy, and utilizes its elasticity to drive the fixed plate 501 and the movable plate 502 to move away from each other.

[0069] It is further explained that the fixed plate 501 is provided with a lower clamping portion, and a stepped transition is formed between the lower clamping portion and the fixed plate 501; the movable plate 502 is provided with an upper clamping portion, and a stepped transition is formed between the upper clamping portion and the movable plate 502; wherein the end of the elastic unit 6 is a U-shaped structure, and the end of the elastic unit 6 is clamped at the corresponding stepped transition to avoid looseness between the elastic unit 6 and the corresponding fixed plate 501 or movable plate 502.

[0071] It should also be noted that in the present application, the motor provides power for the rotation of the drive screw, and the axial movement of the drive screw is achieved through the threads and screw holes on its outer wall. The thread matching method makes the axial movement of the drive bolt smoother and more accurate, ensuring that when pressure is applied to the movable plate 502, the clamping effect of the fixed plate 501 and the movable plate 502 can be effectively achieved.

[0072] It is further explained that the reason for separating the driving screw from the movable plate 502 is to prevent the movable plate 502 from rotating with the rotation of the driving screw. In order to ensure the clamping effect of the fixed plate 501 and the movable plate 502, it is necessary to increase the contact area between the movable plate 502 and the rotating plate 7. When the area of ​​the movable plate 502 is larger, it will cause a larger space to be occupied when rotating with the driving bolt. Therefore, it is necessary to prevent the movable plate 502 from rotating during the clamping process.

[0081] Exemplarily, the rotating plate is a fan-shaped structure, and the outer ring edge of the rotating plate extends between the fixed plate and the movable plate.

[0082] It should also be noted that the rotating plate 7 is a fan-shaped structure, so that when the rotating plate 7 rotates, no matter at what angle, the outer edge of the rotating plate 7 can always be located between the fixed plate 501 and the movable plate 502.
