Description

Technical Field

[0001] The present invention relates to the field of power conversion, and in particular to a green, low-carbon and sustainable power conversion device. Background Art

[0002] A power conversion device is a device or system that can convert power from one form to another. It can receive power input from different energy sources (such as mechanical energy, hydraulic energy, pneumatic energy, etc.) and convert it into a power form suitable for specific applications according to demand, thereby realizing power transmission, regulation and control to meet the power requirements of various machinery, industrial and transportation equipment, etc., and improve power utilization efficiency and flexibility.

[0003] During the use of electric vehicles, when braking, the rotation of the tires is stopped by squeezing and friction, resulting in a waste of kinetic energy. When the kinetic energy is converted and recovered during braking, the kinetic energy loss is different for different braking intensities. If the same power conversion is used, some kinetic energy will still be wasted. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a green, low-carbon and sustainable power conversion device.

[0005] The present invention provides a green, low-carbon and sustainable power conversion device, comprising two mounting shells symmetrically mounted on both sides of a tire, and further comprising:

[0006] Two sets of mobile boxes are respectively installed on opposite sides of the two installation shells;

[0007] Two sets of friction wheels are respectively installed inside the two sets of moving boxes;

[0008] Two brake pushers are respectively installed inside the two mounting shells, and are respectively used to be triggered by brake lines when braking to push the moving box to move, thereby driving the friction wheels to squeeze the two sides of the tire, so that the friction wheels are driven to rotate when the tire rotates;

[0009] Two sets of power conversion components are respectively installed inside the two sets of moving boxes. When the friction wheel rotates, it drives the power conversion components to start converting and storing kinetic energy.

[0010] When the electric vehicle brakes, the brake pusher is driven by the brake line, prompting the mobile box to move, thereby causing the friction wheel to squeeze the two sides of the tire. At this time, the rotation of the tire drives the friction wheel to rotate, and the friction wheel then drives the power conversion component to realize kinetic energy conversion and storage. At the same time, in the process of the tire driving the power conversion component to convert kinetic energy, the kinetic energy of the tire is consumed, thereby playing the role of braking and deceleration. The rotation of the tire during braking is utilized to convert and recover the kinetic energy that would have been wasted due to squeezing and friction during the braking process through the friction wheel and the power conversion component. On the one hand, it effectively reduces the kinetic energy waste when the electric vehicle brakes and improves the energy utilization efficiency. On the other hand, according to different braking intensities, the degree of squeezing between the friction wheel and the tire of the device, the amount of squeezing and the operation of the power conversion component will be adjusted accordingly, which can more accurately match the kinetic energy recovery amount, thereby maximizing energy recycling and utilization, which is in line with the concept of green, low-carbon and sustainable development, and is of great value to improving the energy economy and environmental protection performance of electric vehicles.

[0011] Preferably, it also includes:

[0012] A plurality of the movable boxes form a group, and the movable boxes in the same group are arranged in a linear array along the track of the installation shell;

[0013] Two brake pads are respectively installed inside the two mounting shells, and the brake pads are arranged at the end along the linear array track of the moving box;

[0014] The brake pusher drives the movable box to move in sequence as the pulling degree of the brake wire increases, triggering the friction wheel and the brake pad at the end;

[0015] Each moving box group is composed of multiple moving boxes and is arranged in a linear array along the trajectory of the mounting shell. When the brake pusher increases with the pulling degree of the brake line, it will drive the moving boxes to move in sequence, so that as the braking degree increases, the amount of kinetic energy conversion can be increased. Initially, the movement of the moving box will trigger the contact between the friction wheel and the tire, thereby starting the energy recovery process. As the pulling degree of the brake line increases further, the next moving box moves, causing the second friction wheel to contact the tire and start the energy recovery process, and so on, eventually triggering the contact between the brake pad and the tire at the end. At this time, the friction between the brake pad and the tire increases, further slowing down the rotation of the tire until it stops completely. In summary, according to the different braking strengths, the The braking force on the tires is gradually increased, thereby more effectively controlling the recovery and consumption of kinetic energy. During light braking, energy is recovered only through the friction wheels, reducing the waste of kinetic energy. During heavy braking, the intervention of the brake pads can provide stronger braking force to ensure driving safety. This mechanism of graded braking and energy recovery not only improves the energy utilization efficiency, but also enhances the reliability and adaptability of the braking system, providing strong support for the green and low-carbon operation of electric vehicles. Through the synergistic effect of the friction wheels and brake pads, effective kinetic energy recovery and graded braking are achieved, which improves energy utilization efficiency, reduces kinetic energy waste, and enhances the reliability and adaptability of the braking system, thereby providing an innovative solution for the sustainable development of electric vehicles.

[0016] Preferably, the brake pusher includes:

[0017] A push frame is slidably mounted inside the mounting shell;

[0018] A plurality of inclined surfaces are respectively provided on the top of the moving box and the brake pad, and the inclined surfaces are adapted to the bottom inclination of the pushing frame;

[0019] An arc-shaped rack fixed to the top of the pushing frame;

[0020] a first gear rotatably mounted inside the mounting housing, the first gear meshing with the arc-shaped rack;

[0021] A rotating disk is rotatably mounted inside the mounting shell via a bracket;

[0022] a second gear fixed to the bottom of the rotating disk, the second gear meshing with the first gear;

[0023] A pulling cable, one end of which is wound around the outside of the rotating disk and the other end of which is connected to a path extension mechanism, wherein the path extension mechanism is installed inside the mounting shell and amplifies the pulling path and pulls the pulling cable when the brake line is pulled;

[0024] When the brake cable is pulled, the path growth mechanism amplifies the pulling path and pulls the pulling cable. The pulling cable is wrapped around the outside of the rotating disk, thereby driving the rotating disk to rotate. The rotating disk is rotatably installed inside the mounting shell through a bracket. A second gear is fixed to the bottom of the rotating disk. After the rotating disk rotates, it drives the second gear at the bottom to rotate. The second gear meshes with the first gear to drive the first gear to rotate. The first gear meshes with the arc-shaped rack to drive the arc-shaped rack to move. The arc-shaped rack is fixed to the top of the pushing frame, thereby driving the pushing frame to move. The bottom of the pushing frame is adapted to the inclined surface of the moving box and the top of the brake pad. As the pushing frame moves, the inclined surface cooperates to push the moving box to move in sequence, triggering the friction wheel and the brake pad at the end in sequence. Through the setting of the path growth mechanism, the pulling path of the brake cable can be effectively amplified, thereby achieving more precise control of the braking intensity and the amount of kinetic energy recovery. The moving box and the brake pad can be triggered in sequence to achieve graded braking and energy recovery, thereby improving energy utilization efficiency, reducing kinetic energy waste, and enhancing the reliability and adaptability of the braking system, providing strong support for the green and low-carbon operation of electric vehicles.

[0025] Preferably, the path growth mechanism includes:

[0026] A fixing frame, fixed inside the mounting shell;

[0027] a first movable frame, slidably mounted inside the mounting shell;

[0028] Two sets of pulleys are respectively installed on opposite sides of the fixed frame and the first movable frame, and the other end of the pulling cable passes through each of the pulleys of the two sets in sequence and is then fixed to the fixed frame;

[0029] a first guide tube, fixed on the fixing frame, through which the pulling cable passes;

[0030] a first electric telescopic rod, fixed between the fixed frame and the first movable frame;

[0031] a second guide tube, fixed inside the mounting housing, through which the brake line passes;

[0032] When the brake line is pulled, the brake line passes through the second guide tube and is connected to the first movable frame. When the brake line pulls the first movable frame, the first electric telescopic rod receives a pulling force, and the first electric telescopic rod is fixed between the fixed frame and the first movable frame. When the first electric telescopic rod is subjected to a pulling force, the first electric telescopic rod starts to extend a specified distance, so that the movement of the first movable frame can be controlled as the brake line is pulled. The other end of the pulling cable passes through the fixed frame and the pulley on the first movable frame and the first guide tube in sequence and is fixed to the fixed frame. When the brake line is pulled, the first movable frame moves under the action of the first electric telescopic rod, and the pulley changes the movement direction and path of the pulling cable. The pulling path of the pulling cable is extended, thereby amplifying the pulling distance of the brake line. This path growth mechanism enables the brake pusher to more accurately control the triggering sequence and degree of the moving box and brake pads, thereby improving the sensitivity and accuracy of the braking operation. It not only enhances the control accuracy of the braking system, but also makes the kinetic energy recovery process more efficient and controllable. First, the extended pulling path allows for more delicate adjustment of the braking intensity during the braking process, thereby achieving more accurate energy recovery control. Secondly, the arrangement of the pulley and the first guide tube and the second guide tube reduces the friction and wear of the pulling cable and the brake line during movement, thereby improving the reliability and service life of the system.

[0033] Preferably, the brake pusher further comprises:

[0034] a slide rail, fixed inside the slide rail;

[0035] An extrusion rod is slidably mounted on the slide rail, and the extrusion rod is slidably mounted on the bottom of the pushing frame;

[0036] The slide rail is fixed inside the mounting shell, and the extrusion rod is slidably installed on the slide rail, and the extrusion rod is also slidably installed on the bottom of the pushing frame. When the brake line is pulled, the pushing frame moves, and the extrusion rod slides accordingly on the slide rail. After the pushing frame drives the extrusion rod to slide to the slide rail, the pushing frame and the extrusion rod slide relative to each other, so that after the pushing frame moves through the moving box, the extrusion rod can continuously squeeze the moving box until the pushing frame is reset, thereby improving the stability of pushing the moving box, and at the same time enhancing the stability and durability of the entire braking system, reducing problems such as brake failure or insufficient kinetic energy recovery caused by unstable movement of components, and improving the stability and safety of electric vehicles.

[0037] Preferably, the power conversion assembly includes:

[0038] A micro generator installed inside the mobile box;

[0039] a gear set comprising a driving wheel and a driven wheel, wherein the driving wheel is fixed to the rotating shaft of the friction wheel, and the driven wheel is mounted on the output shaft of the micro-generator;

[0040] a micro battery, fixedly installed inside the mobile box, for storing the electrical energy generated by the micro generator;

[0041] The gear set consists of a driving wheel fixed on the friction wheel shaft and a driven wheel installed on the output shaft of the micro-generator. When the vehicle brakes, the friction wheel is squeezed by the tire and rotates, driving the driving wheel of the gear set to rotate. Through the gear meshing transmission, the driven wheel rotates accordingly, driving the micro-generator to operate, converting mechanical energy into electrical energy, and then the generated electrical energy is stored in the micro-battery fixed in the mobile box. With the help of the coordinated cooperation of the friction wheel and the gear set, kinetic energy is recovered and converted into electrical energy when the vehicle brakes. First, the vehicle braking energy is recovered, the energy utilization rate is improved, and the cruising range of the electric vehicle is extended. Second, the cooperation between the micro-generator and the micro-battery enables the recovered energy to be efficiently stored and reused, enhancing the vehicle's energy self-sufficiency. Third, in the process of power conversion, the kinetic energy is consumed, thereby achieving the effect of braking.

[0042] Preferably, it also includes:

[0043] Main battery, used to store electrical energy;

[0044] a controller, configured to monitor the working state of the main battery and, when both the main battery and the microbattery are in a stopped working state, control the microbattery to charge the main battery;

[0045] When the vehicle brakes, the friction wheel drives the gear set to rotate, driving the micro-generator to convert mechanical energy into electrical energy and store it in the micro-battery. The controller monitors the working status of the main battery and the micro-battery in real time. When the main battery is in a stopped state and the micro-battery is not in a charging state, the controller controls the micro-battery to charge the main battery, thereby realizing the effective utilization and transmission of electrical energy. Through the intelligent management of the controller, it ensures that the electrical energy generated by the micro-battery can be replenished to the main battery in time, thereby improving the utilization efficiency of the entire power system and avoiding the waste of electrical energy. Especially under conditions of frequent braking and parking, the recovered kinetic energy can be effectively utilized, further improving the energy economy and environmental protection performance of electric vehicles, providing a more optimized energy management solution for the green and low-carbon operation of the vehicle, and can avoid the main battery and micro-battery from being charged and discharged at the same time, which is beneficial to protecting the battery.

[0046] Preferably, the brake pusher further comprises:

[0047] a heat dissipation fan, installed inside the installation shell;

[0048] A switching transmission member is installed between the cooling fan and the closest moving box, and is used to connect the friction wheel so that the friction wheel drives the cooling fan to rotate;

[0049] a counter for recording the number of braking operations after the switching transmission member is started and reset, and when the number of braking operations reaches a specified value, the controller controls the switching transmission member to start again;

[0050] The cooling fan is installed inside the mounting shell, and the switching transmission connects the cooling fan to the friction wheel in the nearest moving box. When the friction wheel rotates, the cooling fan is driven to rotate through the switching transmission to realize the heat dissipation function. The counter is used to record the number of brakes after the switching transmission is started and reset. When the number of brakes reaches the specified value, the controller controls the switching transmission to start again, so as to ensure that the cooling fan works when needed when braking frequently. The rotation of the cooling fan can effectively reduce the temperature inside the mounting shell, improve the working efficiency and life of components such as micro generators and micro batteries, and reduce performance degradation or damage caused by overheating. The design of the switching transmission enables the cooling fan to start only when needed, avoiding unnecessary energy consumption and improving the energy utilization efficiency of the entire device. The cooperation between the counter and the controller realizes intelligent heat dissipation control, and automatically adjusts the working state of the cooling fan according to the actual braking frequency and heat dissipation requirements, further optimizing the operating performance and reliability of the device, and providing a strong guarantee for the stable operation of the entire power conversion device.

[0051] Preferably, the switching transmission member includes:

[0052] The driven wheel is slidably plugged into the output shaft of the micro-generator;

[0053] A second movable frame is sleeved on the outer ring of the output shaft of the micro-generator;

[0054] a fourth gear, rotatably mounted on one end of the driven wheel and meshingly matched with the driving wheel;

[0055] a second electric telescopic rod, installed between the second mobile frame and the micro-generator;

[0056] a third gear rotatably mounted on the second movable frame, the third gear being meshed with the fourth gear;

[0057] a worm, rotatably mounted inside the mounting housing, the worm being adapted to the third gear;

[0058] a transmission gear set, installed between the worm and the rotating shaft of the cooling fan;

[0059] The driven wheel is slidably connected to the output shaft of the micro-generator, the second movable frame is sleeved on the outer ring of the output shaft of the micro-generator, the fourth gear is rotatably installed at one end of the driven wheel, and is meshed with the driving wheel, the second electric telescopic rod is installed between the second movable frame and the micro-generator, and is used to control the movement of the second movable frame, the third gear is rotatably installed on the second movable frame, and is meshed with the fourth gear, the worm is rotatably installed inside the mounting shell, and is adapted to the third gear, and the transmission gear set is installed between the worm and the rotating shaft of the cooling fan. When the cooling fan needs to be started, the controller controls the second electric telescopic rod to extend and retract, driving the second movable frame to move, so that the fourth gear is meshed with the driving wheel. At this time, the friction wheel rotates to drive the driving wheel to rotate, and the driving wheel The third gear is driven to rotate by the fourth gear, and the third gear drives the cooling fan's shaft to rotate through the worm and the transmission gear set to realize the rotation of the cooling fan. After the cooling fan rotates, the counter records the number of brakes. When the specified value is reached, the controller controls the switching transmission member to start the cooling fan again. Through the cooperation of the second electric telescopic rod and the second mobile frame, the fourth gear is flexibly engaged and separated from the driving wheel, so that the cooling fan is started only when needed, avoiding unnecessary energy consumption. At the same time, the coordinated work of the counter and the controller makes the startup of the cooling fan more intelligent, and automatically adjusts the working state of the cooling fan according to the actual braking frequency and heat dissipation requirements, further optimizing the operating performance and reliability of the device.

[0060] Preferably, it also includes:

[0061] The controller is further configured to control the switching transmission member to start again when the number of braking times has not reached a specified value but when a specified time has passed between the start and reset of the switching transmission member;

[0062] The counter records the number of brake times. When the number reaches the specified value or does not reach the specified value but the interval time reaches the specified value, the controller starts switching the transmission parts. The intelligent control of the controller enables the cooling fan to start according to actual needs, improves the power conversion and recovery efficiency, achieves energy saving and extends the life of the equipment.

[0063] Compared with the prior art, the present invention has the following beneficial effects:

[0064] 1. The kinetic energy that would otherwise be wasted due to squeezing and friction during braking is converted and recovered through the friction wheel and power conversion assembly, thereby improving energy utilization efficiency. The kinetic energy recovery amount is more accurately matched to different braking intensities, maximizing energy recovery and utilization.

[0065] 2. By sliding the pushing frame and the squeezing rod relative to each other, after the pushing frame moves through the moving box, the squeezing rod can continuously squeeze the moving box until the pushing frame is reset, thereby improving the stability of pushing the moving box, while enhancing the stability and durability of the entire braking system, reducing problems such as brake failure or insufficient kinetic energy recovery caused by unstable component movement, and improving the stability and safety of electric vehicle driving.

[0066] 3. Through the intelligent management of the controller, it ensures that the electric energy generated by the micro-battery can be replenished to the main battery in time, improving the utilization efficiency of the entire power system and avoiding the waste of electric energy. Especially under the working conditions of frequent braking and parking, it can effectively utilize the recovered kinetic energy, further improve the energy economy and environmental performance of electric vehicles, and provide a more optimized energy management solution for the green and low-carbon operation of vehicles.

DETAILED DESCRIPTION

[0074] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0075] like Figures 1 to 6 The green, low-carbon, sustainable power conversion device shown includes two mounting shells 101 symmetrically mounted on both sides of a tire 1, and further includes:

[0076] Two sets of moving boxes 103 are installed on opposite sides of the two mounting shells 101;

[0077] Two sets of friction wheels 104 are respectively installed inside the two sets of moving boxes 103;

[0078] Two brake pushers are respectively installed inside the two mounting shells 101 and are used to be triggered by the brake wires 102 when braking to push the moving box 103 to move, thereby driving the friction wheels 104 to squeeze the two sides of the tire 1, so that the friction wheels 104 rotate when the tire 1 rotates;

[0079] Two sets of power conversion components are installed inside the two sets of moving boxes 103 respectively. When the friction wheel 104 rotates, it drives the power conversion components to start the conversion and storage of kinetic energy;

[0080] During the use of electric vehicles, during the braking process, the rotation of the tires is stopped by squeezing and friction, resulting in a waste of kinetic energy. When the kinetic energy is converted and recovered during the braking process, the loss of kinetic energy is different for different braking intensities. If the same power conversion is used, some kinetic energy will still be wasted.

[0081] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows. When the electric vehicle brakes, the brake pusher is driven by the brake wire 102, causing the movable box 103 to move, thereby causing the friction wheel 104 to squeeze the two sides of the tire 1. At this time, the rotation of the tire 1 drives the friction wheel 104, which in turn drives the power conversion assembly to achieve kinetic energy conversion and storage. At the same time, the tire 1 consumes the kinetic energy of the tire 1 during the kinetic energy conversion process, thereby achieving a braking and deceleration effect. The rotation of the tire 1 during braking is used to convert the kinetic energy that would otherwise be wasted due to squeezing and friction during the braking process into and recovered by the friction wheel 104 and the power conversion assembly. On the one hand, this effectively reduces the kinetic energy waste during braking of the electric vehicle and improves energy utilization efficiency. On the other hand, the degree and amount of squeezing between the friction wheel 104 and the tire 1 and the operation of the power conversion assembly are adjusted accordingly according to different braking intensities, which can more accurately match the kinetic energy recovery amount, thereby maximizing energy recovery and utilization. This is in line with the concepts of green, low-carbon and sustainable development, and is of great value in improving the energy economy and environmental performance of electric vehicles.

[0082] As an optional embodiment, it also includes:

[0083] A plurality of moving boxes 103 form a group, and the moving boxes 103 in the same group are arranged in a linear array along the track of the installation shell 101;

[0084] Two brake pads 6 are respectively installed inside the two mounting shells 101, and the brake pads 6 are arranged at the end along the linear array track of the moving box 103;

[0085] As the pulling degree of the brake wire 102 increases, the brake pusher drives the moving box 103 to move the triggering friction wheel 104 and the brake pad 6 at the end in turn;

[0086] Each moving box 103 group is composed of a plurality of moving boxes 103, and is arranged in a linear array along the trajectory of the mounting shell 101. When the brake pusher increases with the pulling degree of the brake line 102, it will drive the moving boxes 103 to move in sequence, so that as the braking degree increases, the amount of kinetic energy conversion can be increased. Initially, the movement of the moving box 103 will trigger the contact between the friction wheel 104 and the tire 1, thereby starting the energy recovery process. As the pulling degree of the brake line 102 further increases, the next moving box 103 moves, causing the second friction wheel 104 to contact the tire 1 and start the energy recovery process. And so on, eventually triggering the brake pad 6 at the end to contact the tire 1. At this time, the friction between the brake pad 6 and the tire 1 increases, further slowing down the rotation of the tire 1 until it stops completely. In the embodiment of the present invention, the braking force on the tire 1 is gradually increased according to the different braking intensities, so as to more effectively control the recovery and consumption of kinetic energy. During light braking, energy is recovered only through the friction wheel 104, which reduces the waste of kinetic energy. During heavy braking, the intervention of the brake pad 6 can provide stronger braking force to ensure driving safety. This mechanism of graded braking and energy recovery not only improves the energy utilization efficiency, but also enhances the reliability and adaptability of the braking system, providing strong support for the green and low-carbon operation of electric vehicles. Through the synergistic effect of the friction wheel 104 and the brake pad 6, effective recovery of kinetic energy and graded braking are achieved, which improves the energy utilization efficiency, reduces the waste of kinetic energy, and enhances the reliability and adaptability of the braking system, thereby providing an innovative solution for the sustainable development of electric vehicles.

[0087] As an optional embodiment, the brake pusher includes:

[0088] The push frame 2 is slidably mounted inside the mounting shell 101;

[0095] When the brake line 102 is pulled, the path growth mechanism amplifies the pulling path and pulls the pulling rope 205. The pulling rope 205 is wound around the outside of the rotating disk 204, thereby driving the rotating disk 204 to rotate. The rotating disk 204 is rotatably installed inside the mounting shell 101 through the bracket 206. A second gear 203 is fixed to the bottom of the rotating disk 204. After the rotating disk 204 rotates, it drives the second gear 203 at the bottom to rotate. The second gear 203 is engaged with the first gear 202 to drive the first gear 202 to rotate. The first gear 202 is engaged with the arc rack 201 to drive the arc rack 201 to move. The arc rack 201 is fixed to the top of the pushing frame 2, thereby driving the pushing frame 2 to move. The bottom of the pushing frame 2 is adapted to the inclined surface 207 on the top of the moving box 103 and the brake pad 6. As the pushing frame 2 moves, the inclined surface 207 cooperates to push the moving box 103 to move in sequence, triggering the friction wheel 104 and the brake pad 6 at the end in sequence. Through the setting of the path growth mechanism, the pulling path of the brake line 102 can be effectively amplified, thereby achieving more precise control of the braking intensity and the amount of kinetic energy recovery. The moving box 103 and the brake pad 6 can be triggered in sequence to achieve graded braking and energy recovery, thereby improving energy utilization efficiency, reducing kinetic energy waste, and enhancing the reliability and adaptability of the braking system, providing strong support for the green and low-carbon operation of electric vehicles.

[0098] The first movable frame 304 is slidably mounted inside the mounting housing 101;

[0099] Two sets of pulleys 301 are installed on opposite sides of the fixed frame 3 and the first movable frame 304, respectively. The other end of the pulling rope 205 passes through each of the two sets of pulleys 301 in sequence and is then fixed to the fixed frame 3.

[0100] A first guide tube 302 is fixed to the fixing frame 3, and the pulling cable 205 passes through the first guide tube 302;

[0101] The first electric telescopic rod 303 is fixed between the fixed frame 3 and the first movable frame 304;

[0102] A second guide tube 305 is fixed inside the mounting housing 101 , and the brake line 102 passes through the second guide tube 305 ;

[0103] When the brake line 102 is pulled, the brake line 102 passes through the second guide tube 305 and is connected to the first movable frame 304. When the brake line 102 pulls the first movable frame 304, the first electric telescopic rod 303 receives the pulling force. The first electric telescopic rod 303 is fixed between the fixed frame 3 and the first movable frame 304. When the first electric telescopic rod 303 is pulled, the first electric telescopic rod 303 starts to extend a specified distance, so that the movement of the first movable frame 304 can be controlled as the brake line 102 is pulled. The other end of the pulling cable 205 passes through the fixed frame 3 and the pulley 301 on the first movable frame 304 and the first guide tube 302 in sequence and is fixed to the fixed frame 3. When the brake line 102 is pulled, the first movable frame 304 moves under the action of the first electric telescopic rod 303. The pulley 301 changes the movement direction and path of the pulling cable 205, so that the pulling path of the pulling cable 205 is extended, thereby amplifying the pulling distance of the brake line 102. This path growth mechanism enables the brake pusher to more accurately control the triggering sequence and degree of the moving box and the brake pad, thereby improving the sensitivity and accuracy of the braking operation, which not only enhances the control accuracy of the braking system, but also makes the kinetic energy recovery process more efficient and controllable. First, the extended pulling path allows for more delicate adjustment of the braking intensity during the braking process, thereby achieving more accurate energy recovery control. Secondly, the arrangement of the pulley 301 and the first guide tube 302 and the second guide tube 305 reduces the friction and wear of the pulling cable 205 and the brake line 102 during movement, thereby improving the reliability and service life of the system.

[0107] The slide rail 701 is fixed inside the mounting shell 101, and the extrusion rod 7 is slidably installed on the slide rail 701, and the extrusion rod 7 is also slidably installed on the bottom of the pushing frame 2. When the brake line 102 is pulled, the pushing frame 2 moves, and the extrusion rod 7 slides accordingly on the slide rail 701. After the pushing frame 2 drives the extrusion rod 7 to slide to the slide rail 701, the pushing frame 2 and the extrusion rod 7 slide relative to each other, so that after the pushing frame 2 moves through the moving box 103, the extrusion rod 7 can continuously squeeze the moving box 103 until the pushing frame 2 is reset, thereby improving the stability of pushing the moving box 103, and at the same time enhancing the stability and durability of the entire braking system, reducing problems such as brake failure or insufficient kinetic energy recovery caused by unstable movement of components, and improving the stability and safety of electric vehicles.

When the vehicle brakes, friction wheel 104 is squeezed by the tire and rotates, driving the driving wheel of gear set 401. Through gear meshing, the driven wheel rotates accordingly, driving micro-generator 4, converting mechanical energy into electrical energy. The generated electrical energy is then stored in micro-battery 402 fixed in mobile box 103. The coordinated cooperation between friction wheel 104 and gear set 401 recovers kinetic energy during vehicle braking and converts it into electrical energy. This firstly, achieves vehicle braking energy recovery, improving energy utilization and extending the electric vehicle's range.

The controller monitors the operating status of the main battery and micro-battery 402 in real time. When the main battery is in an inoperative state and the micro-battery 402 is not in a charging state, the controller controls the micro-battery 402 to charge the main battery, thereby achieving efficient utilization and transmission of electrical energy. Through the intelligent management of the controller, it is ensured that the electrical energy generated by the micro-battery 402 can be replenished to the main battery in a timely manner, thereby improving the utilization efficiency of the entire power system and avoiding energy waste.

[0134] The working principle of the present invention is as follows: when the electric vehicle brakes, the brake pusher is driven by the brake wire 102, prompting the moving box 103 to move, thereby causing the friction wheel 104 to squeeze the two sides of the tire 1. At this time, the rotation of the tire 1 drives the friction wheel 104 to rotate, and the friction wheel 104 then drives the power conversion assembly to realize kinetic energy conversion and storage. At the same time, the tire 1 consumes the kinetic energy of the tire 1 in the process of driving the power conversion assembly to convert kinetic energy, thereby playing a role in braking and deceleration. Therefore, the rotation of the tire 1 during braking is utilized to convert the kinetic energy that would otherwise be wasted due to squeezing and friction during the braking process into and recovered through the friction wheel 104 and the power conversion assembly. On the one hand, the kinetic energy waste during braking of the electric vehicle is effectively reduced and the energy utilization efficiency is improved. On the other hand, according to different braking intensities, the squeezing degree and squeezing amount of the friction wheel 104 and the tire 1 and the operation of the power conversion assembly will be adjusted accordingly, which can more accurately match the kinetic energy recovery amount, thereby maximizing energy recycling and utilization, conforming to the concept of green, low-carbon and sustainable development, and having important value in improving the energy economy and environmental performance of electric vehicles.
