Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the rescue vehicle with complex terrain passing capability comprises a vehicle frame, a multifunctional wheel module 2, a controller and a wireless module. The controller adopts the micro-control board that the model is arduino 2560. The controller and the wireless module are both arranged in the frame 1. The wireless module is in wireless communication with the upper computer. The frame 1 is provided with a detection sensor and a rescue apparatus. Four multi-functional wheel modules are installed at two sides of the frame in pairs. The multifunction wheel module 2 includes a base 3, a spindle 4, a spindle drive assembly 5, a wheel 6, an obstacle crossing assembly 7, and a clutch assembly 8. The base 3 is fixed to the edge of the frame. A main shaft 4 with a horizontal axis is supported on the base 3; the spindle 4 is driven by a spindle drive assembly 5. The spindle drive assembly 5 includes a spindle power motor 5-1 and a spindle drive gear 5-2. A main shaft power motor 5-1 is fixed on the base 3; the two main shaft driving gears 5-2 are respectively fixed with an output shaft of a main shaft power motor 5-1 and a main shaft 4. The two spindle drive gears 5-2 mesh. The wheel 6 is fixed on the main shaft 4.
As shown in fig. 3 and 5, the obstacle crossing assembly 7 and the clutch assembly 8 are located between the wheel 6 and the base 3. The obstacle crossing assembly 7 comprises a sleeve 7-1, an elastic strip 7-2, a pull rope 7-3 and a winding assembly 7-4. The sleeve 7-1 is sleeved on the main shaft 4 and forms a cylindrical pair with the main shaft 4. The inner end of the elastic strip 7-2 is fixed with the outer side surface of the sleeve 7-1. One side surface of the elastic strip 7-2 is provided with a plurality of anti-skid lugs. The outer end of the pull rope 7-3 is fixed with the outer end of the elastic strip 7-2. The inner end of the pull rope 7-3 is connected to the take-up assembly 7-4. The winding component 7-4 can wind and quickly release the pull rope 7-3. The elastic strip 7-2 is kept bent by the pulling of the pulling rope 7-3. The anti-skid lugs on the elastic strip 7-2 are positioned on the convex side surface of the elastic strip 7-2.
The winding assembly 7-4 comprises a winding motor 7-4-1, a winding roller 7-4-2, a winding driving gear 7-4-3 and a winding driven gear 7-4-4. The winding motor 7-4-1 is fixed on the side surface of the sleeve 7-1. The winding roller 7-4-2 is supported on the side surface of the sleeve 7-1; the inner end of the pull rope 7-3 is wound and fixed on the winding roller 7-4-2. The winding driving gear 7-4-3 and the winding driven gear 7-4-4 are respectively fixed with the winding motor 7-4-1 and the winding roller 7-4-2. And an incomplete gear is adopted as the winding driving gear 7-4-3. The winding driving gear 7-4-3 is meshed with the winding driven gear 7-4-4. Because the rolling driving gear 7-4-3 is an incomplete gear, when the rolling driving gear 7-4-3 rotates to a certain degree, the tooth-missing part of the rolling driving gear 7-4-3 rotates to the rolling driven gear 7-4-4, the rolling driven gear 7-4-4 loses constraint, and the elastic strip 7-2 pops up under the action of self elasticity, so that the function of bouncing is realized.
As shown in FIG. 4, the clutch assembly 8 includes a first clutch pawl 8-1, a second clutch pawl 8-2, a first annular pull plate 8-3, a second annular pull plate 8-4, a shape memory alloy strip 8-5, a return spring 8-6 and a friction lock assembly 9. The first clutch claw 8-1 is fixed with the main shaft 4. The second clutch pawl 8-2 is fixed with the end of the sleeve 7-1. The opposite side surfaces of the first clutch claw 8-1 and the second clutch claw 8-2 are provided with mutually matched locking teeth. When the second clutch claw 8-2 is driven by the sleeve 7-1 to slide to a state of being butted with the first clutch claw 8-1; the first clutch claw 8-1 and the second clutch claw 8-2 are locked with each other and kept fixed. At this time, the sleeve 7-1 is fixed with the main shaft 4; when the first clutch claw 8-1 is separated from the second clutch claw 8-2, the sleeve 7-1 and the main shaft 4 can rotate relatively.
The first annular pull disc 8-3 is sleeved on the sleeve 7-1 and is fixed with the sleeve 7-1 or forms a revolute pair; the second annular pull disc 8-4 is sleeved on the main shaft 4 and forms a rotating pair with the main shaft 4.

A plurality of return springs 8-6 and a plurality of shape memory alloy strips 8-5 are arranged between the opposite side surfaces of the first annular pull disc 8-3 and the second annular pull disc. When the shape memory alloy strip 8-5 is electrified, the distance between the first annular pull disc 8-3 and the second annular pull disc is shortened, so that the sleeve 7-1 is driven to move, and the first clutch claw 8-1 is in butt joint with the second clutch claw 8-2. When the shape memory alloy strip 8-5 is powered off, the first clutch claw 8-1 and the second clutch claw 8-2 are automatically separated under the action of the spring.
The friction locking assembly 9 includes a friction ring 9-1 and a friction lever 9-2. The friction ring 9-1 is fixed to the end of the sleeve 7-1 near the base 3. One end of the friction rod 9-2 is fixed with the base 3, and the other end corresponds to the position of the friction ring 9-1. When the first clutch claw 8-1 is engaged with the second clutch claw 8-2, the friction lever 9-2 is separated from the friction ring 9-1 so as not to block the sleeve 7-1 from rotating. When the first clutch claw 8-1 is separated from the second clutch claw 8-2, the friction rod 9-2 is in contact with the friction ring 9-1, so that the sleeve 7-1 cannot rotate under the action of friction force, and the elastic strip 7-2 can be always kept suspended in the rotating process of the wheel 6. The first clutch claw 8-1 and the second clutch claw 8-2 are jointed when climbing stairs, so that the elastic strip 7-2 rotates when climbing stairs. Under other working conditions, the first clutch claw 8-1 and the second clutch claw 8-2 are separated, so that the elastic strip 7-2 is kept static.
The multifunction wheel module 2 has three operating states:
in the first working state, the winding motor 7-4-1 drives the winding driving gear 7-4-3 to rotate, the elastic strip 7-2 is bent due to winding of the pull rope 7-3 to reduce resistance, the spindle driving assembly 5 drives the wheel 6 to rotate, and the state is used for normal driving.
In the second working state, the clutch component 8 is electrified, the second clutch claw 8-1 is connected with the first clutch claw 8-2, the bending length of the elastic strip 7-2 is larger than the radius of the wheel 6, the elastic strip 7-2 rotates around the main shaft along with the wheel 6, and the elastic strip 7-2 utilizes the anti-skid lugs to clamp the edge of the step or the barrier so as to realize the assistance of climbing upwards. This state is used to climb stairs or pass over obstacles.
In the third working state, the winding driving gear 7-4-3 rotates 360 degrees, and due to tooth missing, the elastic strip 7-2 contracts first and then springs open quickly, so that jumping is realized.
The rescue vehicle with the complex terrain passing capability has two working modes, namely a walking mode and a stair climbing mode. The six multifunctional wheel modules are sequentially defined as a left front wheel, a left rear wheel, a right front wheel and a right rear wheel along the circumferential direction of the frame.
The driving method of the rescue vehicle with the complex terrain passing capacity comprises the following specific steps:
when the vehicle runs on a road and does not meet an obstacle, the winding motors in the multifunctional wheel modules 2 rotate positively to wind the pull ropes, so that the elastic strips are bent to the maximum degree under the action of the pull ropes. Meanwhile, 8-5 parts of the shape memory alloy strip are powered off, the first clutch claw and the second clutch claw are automatically separated under the action of the spring, the first clutch claw and the second clutch claw are separated, and the friction rod is in contact with the friction ring, so that the sleeve cannot rotate under the action of friction force, the elastic strip can be always kept suspended in the air in the rotating process of the wheel, and the interference of the elastic body to driving is avoided. And finally, each main shaft power motor rotates, the two main shaft power gears are meshed, and the wheels rotate, so that the rescue vehicle runs on the ground.
When an obstacle or a step with the height smaller than the threshold value is encountered, the winding motor in the multifunctional wheel module 2 rotates reversely, the pull rope is released, the elastic strip stretches and expands under the action of the self elastic force, the shape memory alloy strip is electrified and shortens, the distance between the first annular pull disc and the second annular pull disc is shortened, the sleeve is driven to move, and when the second clutch claw slides to be in butt joint with the first clutch claw under the driving of the sleeve; the first clutch claw and the second clutch claw are locked and kept fixed with each other, and the friction rod is separated from the friction ring, so that the elastic strip can rotate along with the wheel. The four wheels continue to rotate, and the convex blocks on the elastic strips in the two multifunctional wheel modules 2 positioned on the front side of the frame are firstly propped against the edge of the obstacle or the step. Then, the two elastic strips rotate to enable the front part of the frame to go over an obstacle or a step; then, the four elastic strips continue to rotate, and the rear part of the vehicle is provided with an obstacle or a step; in addition, the rescue vehicle can continue to drive upwards on steps with a single-level height not exceeding a limit value according to the principle.
When meeting barriers or steps with gullies or heights larger than or equal to the threshold value, the frame is adjusted to a state that the tail part faces forwards; the shape memory alloy strip is electrified and shortened, so that the elastic strip is fixed with the main shaft; the elastic strips are rotated to the oblique lower side of one side of the main shaft away from gullies, obstacles or steps through the rotation of the main shaft; when the elastic strip is wound to the limit position, the winding driving gear 7-4-3 is an incomplete gear, and the winding driven gear loses obstruction; the elastic strips 7-2 are quickly bounced off under the action of the elasticity of the elastic strips to drive the whole vehicle frame to jump, so that the vehicle frame can cross a gully, an obstacle or a step.
