Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Referring to fig. 1 to 6, a rocker arm type equal resistance energy recovery device of the present invention is schematically shown, which includes a first component 1, a second component 2, an energy recovery assembly 3, an elasticity compensation assembly 4 and an electric power storage device.
As shown in fig. 2 and 3, the energy recovery assembly 3 includes a generator 31, a speed increasing device 32, a transmission shaft 33, and a rocker arm 34, and the generator 31 is electrically connected to the electric storage device. The output end of the speed increasing device 32 is connected to the generator 31, the input end is connected to the transmission shaft 33, and the speed increasing device 32 can increase the rotating speed of the transmission shaft 33 to meet the rated rotating speed of the generator 31. The transmission shaft 33 is rotatably connected to the first component 1, the fixed end of the rocker arm 34 is rotatably connected to the second component 2, the movable end of the rocker arm 34 is rotatably connected to the transmission shaft 33 through the one-way clutch assembly 35, and the length direction of the rocker arm 34 is inclined with respect to the relative movement direction of the first component 1 and the second component 2. Preferably, as shown in fig. 7, a spring 36 is disposed between the transmission shaft 33 and the input end of the speed increasing device 32, the spring 36 can isolate the impact force on the transmission shaft 33 from the input end of the speed increasing device 32, so as to prevent the impact force from damaging the generator 31, and at the beginning of the rotation of the generator 31, the spring 36 can also collect and temporarily store the power input by the transmission shaft 33, when the rotation speed of the generator 31 is gradually increased, the spring 36 outputs the temporarily stored power to the generator 31, further, a one-way bearing 37 is disposed between the transmission shaft 33 and the first component 1, the one-way bearing 37 only allows the spring 36 to collect the kinetic energy output by the transmission shaft 33 to the speed increasing device 32, and prevents the spring 36 from reversely transmitting the temporarily stored kinetic energy from the transmission shaft.
When the first component 1 and the second component 2 move back to back, the first component 1 pulls the rocker arm 34 to move, and at the moment, the movable end of the rocker arm 34 moves towards a first preset direction, the one-way clutch assembly 35 is unlocked and allows the movable end of the rocker arm 34 and the transmission shaft 33 to generate relative movement; when the first part 1 and the second part 2 move towards each other, the first part 1 pushes the rocker arm 34 to move, and when the movable end of the rocker arm 34 moves towards the second preset direction, the one-way clutch assembly 35 is locked to lock the movable end of the rocker arm 34 with the transmission shaft 33, and the rocker arm 34 drives the transmission shaft 33 to force the transmission shaft 33 to rotate. This structure enables the first member 1 and the second member 2 to output power from the swing arm 34 to the transmission shaft 33 only when they move toward each other, and the transmission shaft 33 rotates all the way toward the same rotational direction to stably output power toward the generator 31.
The elasticity compensation component 4 comprises an oil tank 41 and a piston cylinder mechanism 42 with two ends respectively connected with the first part 1 and the second part 2, the piston cylinder mechanism 42 is provided with a one-way oil inlet oil path and a one-way oil discharge oil path 43 communicated with the oil tank 41, and the one-way oil discharge oil path 43 is provided with a regulating valve 431 with opening area of a regulating valve 431 through an actuator 432. When the first component 1 and the second component 2 move back to back, oil in the oil tank 41 enters the piston cylinder mechanism 42 from the one-way oil inlet oil path, and when the first component 1 and the second component 2 move towards each other, oil in the piston cylinder mechanism 42 enters the oil tank 41 from the one-way oil outlet oil path 43. Since the charging currents of the power storage device in different charging stages are different, for example, when the power storage device has a small amount of power (the amount of power is 0-80%), the required charging current is large, so that the internal resistance of the generator 31 increases with the increase of the charging current of the power storage device, at this time, the increase of the internal resistance of the generator 31 causes a larger external force to be required to drive the transmission shaft 33 to rotate, that is, the compression resistance of the energy recovery assembly 3 increases, and passengers can feel that the vehicle is bumpy. For this purpose, the actuator 432 adjusts the adjusting valve 431 such that the valve opening area thereof is increased, that is, the compression resistance of the elastic force compensation component 4 is decreased, so as to compensate the compression resistance variation of the energy recovery component 3, and ensure that the total compression resistance of the energy recovery component 3 and the elastic force compensation component 4 is within a preset constant value or a certain resistance value range, thereby avoiding the compression resistance variation of the energy recovery device along with the charging current variation of the electric storage device. In the process of elastic force compensation, the compression resistance of the energy recovery device is equal to the compression resistance of the energy recovery member 3 + the compression resistance of the elastic force compensation member 4.

It will be appreciated that the rocker arm 34 and the transmission 351 constitute a crank and rocker mechanism to convert relative linear motion of the first and second members 1, 2 into rotational motion of the transmission shaft 33. To achieve a similar transmission effect, the one-way clutch assembly 35 may further include a first gear 352 connected to the transmission shaft 33 and a second gear 353 rotatably connected to the movable end of the rocker arm 34 through the one-way clutch, the first gear 352 and the second gear 353 being engaged.
