Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
Example 1: fig. 1 is a schematic structural diagram of an electric bicycle with rollover prevention capability according to embodiment 1. Comprises a frame 1; a front wheel 2; a rear wheel 3; a steering mechanism (steering handle) 4; a control circuit module 5; a dynamic protection wheel 6; a swing arm 7 a; a controllable support bar 7b, etc. Wherein the swing arm 7a and the controllable supporting rod 7b jointly form a controllable protection wheel carrier. In addition, the present embodiment also comprises a battery and a motor for driving running, and the present embodiment is a common electric bicycle or electric motorcycle except for the dynamic protection wheel 6, the control circuit module 5 and the controllable protection wheel frame.
In the specific implementation of the invention, the key part is the controllable protective wheel bracket. The controllable protection wheel support in this embodiment is composed of a swing arm 7a and a controllable support rod 7 b. The swing arm 7a is about 30cm long, the tail end of the swing arm is provided with a dynamic protection wheel 6, the front end of the swing arm is rotatably fixed at the lower part between the front wheel 2 and the rear wheel 3 of the frame through a swing arm shaft, and the swing arm shaft is horizontally arranged along the direction of the middle shaft of the vehicle body, so that the horizontal height of the protection wheel has the largest moving space when the swing arm rotates. One end of the controllable supporting rod 7b is rotatably fixed at the upper part of the frame, the other end of the controllable supporting rod 7b is rotatably connected to the swing arm 7a, a locking device is arranged on the controllable supporting rod 7b, and the controllable supporting rod 7b can be switched between a free state and a locking state through the locking device; when the controllable supporting rod 7b is in a locking state, the length of the controllable supporting rod 7b cannot be compressed, and when the controllable supporting rod 7b is in a free state, the length of the controllable supporting rod can be freely stretched and contracted within a certain range. The swing arm shaft is set at a lower height as far as possible on the premise of meeting the ground clearance requirement, so that the lateral movement abrasion of the protection wheel along the bottom surface caused by the vertical fluctuation and the left and right inclination of the vehicle body can be reduced. The ground clearance should be determined according to the application scenario of the vehicle and the relevant specifications. The swing arm should have a sufficient range of rotation angle (which affects the range of up and down movement of the protection wheel) to ensure that normal vehicle body tilting and passing through obstacles does not affect normal travel due to the protection wheel reaching the limit of the range of movement. In practical cases, the up-and-down moving range of the protection wheel is mainly limited by the contraction length and the extension length of the support rod, and the larger the difference value is, the larger the moving range of the protection wheel is. In the embodiment, the sliding rod 7b1 and the outer tube 7b2 are 45 cm respectively, and the protective wheel can freely move between 10 cm below the ground and 30cm above the bottom surface when the vehicle body is vertical to the ground, so that the requirement of normal driving is completely met.
Fig. 2 is a schematic structural view of the controllable supporting rod 7 b. In the embodiment, the controllable supporting rod 7b is composed of a sliding rod 7b1, an outer tube 7b2, a damping block 7b3, a linkage rod 7b4, a bidirectional self-holding electromagnet 7b5 and a push-pull spring 7b6, the outer tube is provided with a window, one end of each linkage rod 7b4 is rotatably connected with the outer tube 7b2 through a rotating shaft, the other end of each linkage rod 7b4 is rotatably connected with the damping block 7b3 through a rotating shaft, and the damping blocks 7b3 can be always parallel to the sliding rod 7b 1; the bidirectional self-holding electromagnet 7b5 is fixed on the outer tube 7b2, the action rod thereof is connected to the damping block 7b3 or the linkage rod 7b4 through the push-pull spring 7b6, and the two holding positions of the action rod thereof enable the damping block 7b3 to contact or separate from the sliding rod 7b1 through the window of the outer tube 7b 2.
The bidirectional self-holding electromagnet 7b5, the damping block 7b3, the linkage rod 7b4 and the push-pull spring 7b6 form a locking device together. In fig. 2, when the actuating lever of the electromagnet 7b5 is in the push-out (lower right) position, the damping block 7b3 is away from the surface of the sliding rod 7b1, so that the sliding rod 7b1 can slide freely in the outer tube 7b2, i.e. the controllable supporting rod 7b is in a free state; on the contrary, as shown in fig. 3, when the actuating rod of the bidirectional self-holding electromagnet 7b5 is in the retracted (upper left) position, the damping block 7b3 contacts the surface of the sliding rod 7b1, at this time, if the sliding rod 7b1 is pushed inward, the damping block 7b3 follows the movement due to the action of friction force, which further presses the sliding rod 7b1 along with the left rotation of the linkage rod 7b4, so as to increase the friction, realize a self-locking effect and lock, that is, control the supporting rod 7b to enter the locking state. The push-pull spring 7b6 is used for ensuring that the state of the bidirectional self-holding electromagnet 7b5 can be reliably switched at any position of the damping block 7b3, and switching failure is prevented. The skilled person will be able to select the length, spring rate, length, etc. of the linkage rod 7b4 according to the relevant coefficient of friction, ensuring reliable locking and unlocking. The control circuit module 5 can be powered by a power battery of the electric vehicle or an independent battery.
In the electric bicycle of the embodiment, the controllable supporting rod 7b is in a free state in normal running, the dynamic protection wheel 6 freely moves up and down along the road surface under the constraint of the swing arm 7a, and no lateral acting force and no advancing resistance are generated on the bicycle. When the car body sideslips, topples over and the like, the control circuit module 5 can monitor the danger by using the motion sensor thereof, and rapidly drives the locking device, so that the controllable supporting rod 7b is locked and provides supporting force, and the dynamic protection wheel 6 is always in contact with the road surface, so that the supporting protection of the car body can be instantly realized.
The slide bar 7b1 and the outer tube 7b2 are made of high-strength steel or carbon fibre material, with a difference of length not exceeding 2cm, so as to obtain a maximum extension length while ensuring a certain minimum overlap length. The length of contraction and extension and the position of the end connection determine the free travel of the dynamic protection wheel 6.
In order to increase the switching response speed, the damping mass 7b3 should be as light as possible, but has strength requirements, so the damping mass 7b3 in this embodiment is made of carbon fiber material. Other related components may also be made of carbon fiber material.
In order to improve the damping effect, the locking device also comprises an elastic wear-resistant damping piece 7b7 attached to the damping block 7b3, and the surface of the slide rod 7b1 facing the damping block 7b3 is transversely striped to increase the friction coefficient. The damper 7b7 can be made of polyurethane or similar wear-resistant, pressure-resistant, high-friction material.
The control circuit module 5 is firmly installed on the vehicle frame 1, and comprises a motion sensor, an MCU and a current and voltage driving circuit, and the driving output is connected to the bidirectional self-holding electromagnet 7b 5. The control circuit module 5 may detect the inclination angle of the vehicle body, or may connect with the vehicle speed signal to determine the driving state of the vehicle body together. When the situation that the vehicle body has inclination of more than 10 degrees and the like is detected, namely the situation that the vehicle body has a dumping risk is judged, the locking of the controllable supporting rod on the corresponding side is realized by driving the bidirectional self-holding electromagnet 7b5 on the corresponding side, so that the dumping is avoided, and the safety of a driver is protected. Tests prove that most dangerous accidents in daily driving can be avoided by simply carrying out locking control by taking the inclination of 10 degrees as a criterion. While those skilled in the art are fully capable of achieving more sophisticated control in conjunction with other motion parameters.
In reality, there are several causes and mechanisms for the dumping of vehicles, the two most important: one is that the wheels suddenly sideslip due to rain, snow or oil dirt road surface, and the center of the whole vehicle can not move synchronously, so that the vehicle body inclines, the inclined vehicle body causes more serious wheel sideslip, and the vehicle body accelerates to incline and tip over; the other is that the vehicle body inclines due to external force such as impact, a driver cannot control the vehicle body to obliquely swing left and right, the inclination is amplified continuously, and the vehicle turns over. In both cases, the use of the protection device of the invention automatically prevents the vehicle body from tilting too much, thus helping the driver to stabilize the vehicle body and avoid tipping over.
The diameter of the dynamic protection wheel 6 is about half of that of the main wheel and is made of light materials. Since the vehicle can slide laterally with the road surface due to the turning and the inclination of the vehicle body, the surface of the vehicle is made of smooth and wear-resistant materials such as polytetrafluoroethylene materials.
The embodiment adopts a sliding self-locking mode to perform locking control, uses the bidirectional self-holding electromagnet to perform switching drive, and has the advantages of fast switching response, high reliability, low drive power consumption and low cost.
The core device of the control circuit module 5 of the present embodiment is a commonly used MEMS motion sensor MPU6050, which has acceleration sensing and angular velocity sensing functions. The single-chip microcomputer is connected with the electromagnet 7b5 and is connected with a driving circuit capable of outputting bidirectional voltage.
In fact, the design of the above embodiment can be similarly applied to a general motorcycle.
Example 2: the bicycle with the rollover prevention capability of the embodiment is particularly a child bicycle. The controllable protection wheel frame, the dynamic protection wheel, the control circuit module and the like are similar to those in embodiment 1. The positions of the controllable protective wheel frame and the dynamic protective wheel are close to the rear wheel axle so as to avoid the interference with the pedals.
A common child bicycle is characterized in that two sides of a rear wheel of the bicycle are provided with fixed protection wheels in order to prevent children from riding and falling down. Although the bicycle avoids side fall, the normal inclination during riding is limited, and the effect of the tricycle is similar to that of a tricycle, so that the effect and the pleasure of children learning the bicycle are influenced. Meanwhile, the protection wheel cannot play a role in protection when being positioned on a concave road surface, and the vehicle is pushed to the other side when encountering a bulge, so that unsafe factors exist. This embodiment adopts the mode of dynamic protection wheel to replace ordinary protection wheel, and is as no different with ordinary bicycle when normally riding, only provides the support protection when taking place abnormal situation, therefore more does benefit to study the bicycle safely and ride, also does benefit to the improvement of normal in-use security.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modification made on the basis of the technical solution according to the technical idea of the present invention falls within the protection scope of the present invention.
