Description

Technical Field

[0001] The present invention relates to the technical field of power recovery, and in particular to an energy-saving RV power recovery device. Background Art

[0002] With the increasing demand for outdoor travel, RVs are becoming more and more popular as a convenient and comfortable way of travel. However, the kinetic energy of traditional RVs is lost in the form of heat energy during driving and is not effectively recovered, resulting in low energy utilization efficiency. Therefore, power recovery technology has gradually emerged. RV power recovery usually refers to the use of technical means to recover the energy generated by the RV during driving, so as to improve energy efficiency and reduce energy consumption. At the same time, it can ensure the normal operation of the RV and improve the comprehensive performance of the RV. It has broad development prospects.

[0003] In the existing patent CN205131216U, an energy recovery device for a vehicle brake system is disclosed, including a brake caliper and a brake pad. The utility model discloses an energy recovery device for a vehicle brake system by providing a mounting slot for installing an energy recovery module on the brake caliper, and providing an energy storage slot for installing a small rotating generator on the outside of the energy recovery module, and driving the contact transmission wheel to contact the brake pad through the brake caliper, while driving the external transmission wheel, the small transmission gearbox and the small rotating generator to rotate, so as to supply power to the vehicle battery, recover the power into electric energy for the vehicle, greatly save kinetic energy loss, improve the economy of the vehicle, and adopt a modular setting that not only greatly reduces the volume, but also improves the versatility and reduces the cost.

[0004] In the above structure, the effect of braking power recovery can be achieved, but during the driving process of the RV, the braking system and the power recovery system are highly integrated, and the relative independence of the braking system and the power recovery system cannot be achieved. When braking, the power recovery system will follow the action of the braking system, resulting in less energy recovery of the power recovery system, which is not conducive to the RV's control and adjustment ability of power recovery, and is not conducive to the recovery of the RV's power, reducing the recovery rate of the RV's power energy, thereby greatly reducing the energy recovery of the RV during movement, and reducing the overall performance of the RV.

When braking is needed, the power of the wheel body is first recovered, and the braking system drives the mechanical structure to move, forcing the operating component to move. Since the limiting component has a limiting effect on the secondary pullback component, the movement of the operating component forces the primary pullback component to pull back. Under the action of the supporting component, the primary pullback component drives the recovery component to move, forcing the recovery component to drive the transmission component to move until the recovery component contacts the wheel body. Since the rotation of the wheel body drives the recovery component to rotate, the transmission component is forced to rotate, so that the power generation component rotates to generate electrical energy. Since the recovery component is in frictional contact with the wheel body, the wheel body will be braked to achieve the effect of power recovery for the RV. When rapid braking is needed, when the recovery component is in frictional contact with the wheel body, the pressure under the driver's feet increases. At this time, the primary pullback component will act on the limiting component, forcing the limiting component to release the restriction, forcing the primary pullback component and the secondary pullback component to be connected to the operating component. Since the primary pullback component moves to the maximum limit, when the downward pressure increases, the operating component It will drive the secondary pullback component to pull back, forcing the secondary pullback component to move, and the secondary pullback component drives the brake component to move, forcing the brake component to form a secondary brake on the wheel body, so that the wheel body forms a double-sided braking effect, forming an effect of first recovering power and then completing braking; after braking is completed, the operating component retracts to the original position, forcing the limiting component to retract to the original position, limiting the secondary pullback component, until the primary pullback component and the secondary pullback component retract to the original position, forming a release effect on the wheel body; in summary, an energy-saving RV power recovery device of the present application, during the braking process, the brake component and the power recovery component respectively form independent systems, when braking, the recovery component does not follow the action of the brake component, the recovery component moves before the brake component, so that the recovery energy of the power recovery component is more, which is beneficial to the recovery of power and energy of the RV, and improves the power and energy recovery rate of the RV. When braking quickly, the double-sided braking effect of the wheel body can be achieved, and the control and adjustment ability of the RV on power recovery and braking is improved, thereby greatly improving the energy recovery of the RV during movement and improving the comprehensive performance of the RV.

DETAILED DESCRIPTION

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] Embodiment 1:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, an energy-saving RV power recovery device of the present invention includes a mounting frame 1, a drive shaft 2 is connected to a bearing on the mounting frame 1, a wheel body 3 is fixedly sleeved on the drive shaft 2, a support assembly 4 is provided on the mounting frame 1, a recovery assembly 5 in contact with the wheel body 3 is provided on the support assembly 4, a power generation assembly 6 connected to a battery is provided on the mounting frame 1, a transmission assembly 7 is provided on the mounting frame 1 between the power generation assembly 6 and the recovery assembly 5, a brake assembly 8 is provided on the mounting frame 1, and a primary pullback assembly 9 adapted to the recovery assembly 5 and a brake assembly 9 are provided on the mounting frame 1. 8 is matched with a secondary pullback component 10, and an operating component 11 connected to the primary pullback component 9 and the secondary pullback component 10 is arranged on the mounting frame 1, and a limiting component 12 is arranged between the primary pullback component 9 and the secondary pullback component 10, and the limiting component 12 is used to limit the movement of the secondary pullback component 10; wherein, when recovering energy, the operating component 11 moves back, and the primary pullback component 9 forces the recovery component 5 to recover the power of the wheel body 3; when braking quickly, the operating component 11 continues to move back, the limiting component 12 is actuated, and the secondary pullback component 10 forces the brake component 8 to brake.

[0033] Working principle: The power of the RV drives the drive shaft 2 to rotate, and the drive shaft 2 drives the wheel body 3 to travel on the ground. When braking is needed, the power of the wheel body 3 is first recovered, and the braking system drives the mechanical structure to move, forcing the operating component 11 to move. Since the limiting component 12 has a limiting effect on the secondary pullback component 10, the movement of the operating component 11 forces the primary pullback component 9 to pull back. Under the action of the supporting component 4, the primary pullback component 9 drives the recovery component 5 to move, forcing the recovery component 5 to drive the transmission component 7 to move until the recovery component 5 contacts the wheel body 3. Since the wheel body 3 rotates, it drives the recovery component 5 The wheel body 3 is in frictional contact with the recovery component 5, which will brake the wheel body 3, thus achieving the effect of power recovery for the RV. When rapid braking is required, when the recovery component 5 is in frictional contact with the wheel body 3, the pressure under the driver's feet increases. At this time, the first-level pullback component 9 will act on the limiting component 12, forcing the limiting component 12 to release the restriction, forcing the first-level pullback component 9 and the second-level pullback component 10 to be connected to the operating component 11. Since the first-level pullback component 9 moves to the maximum limit, the downward pressure increases. When the vehicle is in a state of being ... The RV power recovery device, during the braking process, the brake component 8 and the power recovery component 5 respectively form independent systems. During braking, the recovery component 5 does not follow the action of the brake component 8, but acts before the brake component 8, so that the power recovery component 5 recovers more energy, which is beneficial to the recovery of the power and energy of the RV, and improves the power and energy recovery rate of the RV. During rapid braking, it can achieve the effect of double-sided braking of the wheel body 3, and improve the RV's control and adjustment capabilities for power recovery and braking, thereby greatly improving the energy recovery of the RV during movement and improving the comprehensive performance of the RV.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, an energy-saving RV power recovery device of the present invention, the limiting component 12 includes an orifice plate 1201 arranged in the storage cylinder 901, the orifice plate 1201 is located between the pull-back piston 1 902 and the pull-back piston 2 1001, a limiting partition 1202 is hinged on the orifice plate 1201, a limiting spring 1203 is arranged between the orifice plate 1201 and the limiting partition 1202, and a push rod 1204 adapted to the limiting partition 1202 is arranged on the pull-back piston 1 902.

[0044] Working principle: When the RV is in motion, the power of the RV drives the drive shaft 2 to rotate through the mechanical structure, and the drive shaft 2 drives the wheel body 3 to rotate and travel on the ground. When braking, that is, when the power of the wheel body 3 needs to be recovered, the driver steps on the brake system, and the mechanical structure moves to force the connecting ring 1104 to move. The connecting ring 1104 pulls the operating rod 1103 to move, forcing the operating rod 1103 to drive the operating piston 1102 to move, so that the operating piston 1102 moves away from the storage cylinder 901, forcing the gas in the operating cylinder 1101 to increase and the pressure to decrease. At this time, the operating spring 1105 is compressed, forcing the gas in the storage cylinder 901 to enter the operating cylinder 1101. Because the limit spring 1203 pulls the limiting partition 1202, the limiting partition 1202 is forced to limit the orifice plate 120 1, at this time, the gas in the storage cylinder 901 is reduced, forcing the pull-back piston 1 902 to move toward the pull-back piston 2 1001 in the storage cylinder 901, the pull-back spring 1 906 is stretched, and the pull-back piston 1 902 pulls the pull-back rod 1 903 to move, forcing the pull-back rod 1 903 to drive the pull-back connecting plate 905 to move, the pull-back connecting plate 905 drives the annular plate 501 to move, the annular plate 501 drives the rotating cylinder 502 to move, the rotating cylinder 502 drives the spring plate 503, the connecting cylinder 504 and the annular friction plate 505 to move, until the annular friction plate 505 contacts the wheel body 3; the annular plate 501 drives the support plate 403 to move, the support plate 403 drives the support inner rod 402 to move in the support outer rod 401, at this time the support spring 404 is compressed, forming a support effect on the annular plate 501;

[0045] At the same time, the rotating cylinder 502 drives the transmission gear 1 701 to move until the transmission gear 1 701 is meshed with the transmission gear 2 702. When the annular friction plate 505 contacts the wheel body 3, the wheel body 3 rotates to drive the annular friction plate 505 to rotate, forcing the connecting cylinder 504, the spring plate 503 and the rotating cylinder 502 to rotate. The connecting cylinder 504 drives the transmission gear 1 701 to rotate. The transmission gear 1 701 rotates to drive the transmission gear 2 702. The transmission gear 2 702 rotates to drive the transmission gear 3 703. The transmission gear 3 703 rotates to drive the rotating gear 603. The rotating gear 603 rotates to drive the rotating shaft 602. The rotating shaft 602 rotates to drive the generator 601 to rotate, so that the generator 601 generates electrical energy and stores it in the battery. At this time, the annular friction plate 505 will form a braking effect on the wheel body 3, convert the mechanical energy of the RV into electrical energy, and store the electrical energy, thereby achieving the effect of power recovery for the RV.

[0046] When rapid braking is required, i.e., emergency braking, the driver's foot pressure increases. Since the annular friction plate 505 contacts the wheel body 3, a blocking effect is formed on the annular friction plate 505. At this time, when the foot pressure increases, the operating rod 1103 drives the operating piston 1102 to increase its movement amplitude, forcing the pull-back piston 1 902 to continue to move forward, and the pull-back piston 1 902 drives the pull-back rod 1 903 to continue to move, forcing the pull-back rod 1 903 to drive the pull-back connecting plate 905 to move, until the baffle plate 904 contacts the storage cylinder 901, and the pull-back connecting plate 905 drives the annular plate 501 to move, and the annular plate 501 drives the rotating cylinder 502, the spring plate 503, the connecting cylinder 504 and the annular friction plate 505 to move. Since the annular friction plate 505 cannot continue to move, the spring plate 503 is forced to compress until the annular friction plate 505 is in close contact with the wheel body 3, forming a further braking effect. At this time, the pull-back piston 1 902 moves to the maximum limit;

[0047] The pull-back piston 902 drives the push rod 1204 to move excessively until the pull-back piston 902 moves to the maximum limit, and the push rod 1204 pushes up the limiting partition 1202, and the limit spring 1203 stretches, forcing the limiting partition 1202 to rotate, so that the limiting partition 1202 no longer restricts the orifice plate 1201, forcing the gas to pass through the orifice plate 1201;

[0048] When braking is needed again, the driver's foot pressure increases again. Since the pull-back piston 1 902 moves to the maximum, the operating rod 1103 is pulled again. At this time, the gas in the storage cylinder 901 decreases, and the gas can pass through the orifice plate 1201, forcing the pull-back piston 2 1001 to move, forcing the pull-back piston 2 1001 to drive the pull-back rod 2 1002 to move, and the pull-back rod 2 1002 drives the brake connecting plate 803 to move. At this time, the pull-back spring 2 1003 is compressed, and the brake connecting plate 803 drives the sliding rod 801 to move, and the sliding rod 801 drives the brake pad 802 to move until the brake pad 802 contacts the wheel body 3. At this time, the brake spring 804 is compressed, forcing the brake pad 802 to brake the wheel body 3 for the second time, so that the wheel body 3 forms a double-sided braking effect, forming an effect of first recovering power and then completing braking;

[0049] After braking, the driver lifts his foot to release the pressure, operating the piston 1102 and the operating rod 1103 to return to their original positions, forcing the limiting component 12, the first-level pullback component 9 and the second-level pullback component 10 to return to their original positions, thereby completing the release effect on the wheel body 3.

[0050] The setting of the support component 4 can achieve the supporting effect of the recovery component 5, and at the same time can move with the recovery component 5, improve the supporting capacity and adaptability, and facilitate the free movement of the recovery component 5; the setting of the recovery component 5 can achieve the recovery effect of the RV power, so that the annular friction plate 505 rotates due to friction, thereby cooperating with the transmission component 7 to achieve power recovery, and the setting of the spring plate 503 can achieve close friction between the annular friction plate 505 and the wheel body 3, improve the braking effect, and at the same time improve the power recovery capacity; the setting of the power generation component 6 can convert mechanical energy into electrical energy, realize the power recovery function of the RV, supply electricity to the RV, and improve the comprehensive performance of the RV; the setting of the transmission component 7 can transmit mechanical energy to the power generation component 6, realize the conversion of mechanical energy into electrical energy, improve the transmission capacity, and when not braking, the transmission gear 701 will not rotate, thereby improving the flexibility of the device; the setting of the brake component 8 can achieve the braking effect on the wheel body 3, cooperate with the recovery component 5 to achieve the effect of double-sided braking, and at the same time decouple the recovery component 5 from the brake component 8, improve the control ability of the device, and improve The first-stage pullback assembly 9 is provided to achieve the pulling effect on the recovery assembly 5, to achieve the control of the recovery assembly 5, thereby achieving the control effect of the device on power recovery, and the baffle 904 is provided to limit the excessive movement of the pullback rod 903; the second-stage pullback assembly 10 is provided to achieve the control effect on the brake assembly 8, and the cooperation with the first-stage pullback assembly 9 realizes the step-by-step control of the brake assembly 8 and the recovery assembly 5, thereby improving the braking effect of the device; the setting of the operating assembly 11 can realize the control effect of the first-stage pullback assembly 9 and the second-stage pullback assembly The step-by-step control capability of the component 10 can realize the effective combination of energy recovery function and braking function, and at the same time, the braking system can be used to control the recovery component 5 and the brake component 8, thereby improving the rationality of the device; the setting of the limiting component 12 makes the first-level pullback component 9 and the second-level pullback component 10 move according to a certain rule, so that the first-level pullback component 9 moves first, and the second-level pullback component 10 moves later, thereby improving the control and adjustment ability of the RV for power recovery and braking, which is beneficial to the recovery of power and energy of the RV and improving the power and energy recovery rate of the RV.

[0051] On the one hand, during the braking process, the braking component 8 and the power recovery component 5 form independent systems respectively. During braking, the recovery component 5 does not follow the action of the braking component 8, but acts before the braking component 8, so that the power recovery component 5 recovers more energy, which is beneficial to the recovery of power and energy of the RV and improves the power and energy recovery rate of the RV. On the other hand, during rapid braking, the double-sided braking effect of the wheel body 3 can be achieved, and the control and adjustment ability of the RV on power recovery and braking is improved, thereby greatly improving the energy recovery of the RV during movement and improving the comprehensive performance of the RV.
