Description

Technical Field

[0001] This invention relates to the field of automotive energy-saving technology, and in particular to an automotive mechanical energy-saving device. Background Technology

[0002] In actual operation, especially in congested urban traffic, traditional gasoline vehicles have poor fuel economy. One major reason is that during braking, deceleration, and downhill coasting, the vehicle's enormous kinetic energy cannot be effectively utilized. Instead, it is dissipated into the atmosphere as heat through friction in the braking system. It is estimated that this wasted kinetic energy can reach more than 50% of the vehicle's driving energy.

[0003] Current gasoline-powered vehicles use intelligent engine start-stop systems, which solve the problem of fuel consumption when the vehicle is idling and reduce the waste of driving energy.

[0004] However, in the aforementioned existing technologies, the energy-saving range of engine start-stop technology is limited, it cannot recover the kinetic energy of vehicle coasting, and the battery cannot supply the display screen for a long time after the fuel vehicle is turned off, affecting the convenience of use. Summary of the Invention

[0005] The purpose of this invention is to provide an automotive mechanical energy-saving device that solves the problems of limited energy-saving range of existing engine start-stop technology, inability to recover vehicle coasting kinetic energy, and the inability of the battery to supply power to the display screen for a long time after the fuel vehicle is turned off, which affects the convenience of use.

[0006] To achieve the above objectives, the present invention provides an automotive mechanical energy-saving device, comprising a universal joint flange and a power generation and storage assembly. The power generation and storage assembly includes a housing, a bearing housing, a first rotating shaft, a docking flange, a one-way clutch, a second rotating shaft, an integrated generator, a battery pack, mounting components, and a speed-increasing component. The power generation and storage assembly is connected to the universal joint flange. The housing is disposed on one side of the universal joint flange. The bearing housing is fixedly connected to the housing and located on one side of the housing. The first rotating shaft is rotatably connected to the bearing housing and located on the inner wall of the bearing housing. The docking flange is fixedly connected to the first rotating shaft. The first rotating shaft is connected to the outer side wall of the first rotating shaft, and the docking flange is detachably engaged with the universal joint flange. The one-way clutch is detachably connected to the first rotating shaft and is located at the end of the first rotating shaft away from the docking flange. The integrated generator is detachably connected to the housing and is located on the inner side wall of the housing. The second rotating shaft is detachably connected to the integrated generator and is located at the input end of the integrated generator. The speed-increasing component is connected to the one-way clutch and the second rotating shaft respectively. The battery pack is disposed on the inner side wall of the housing. The mounting component is connected to the housing and the battery pack respectively.

[0007] The power generation and storage component further includes a connecting harness and an automotive-grade MCU controller. The connecting harness is electrically connected to the battery pack and is located on one side of the battery pack. The automotive-grade MCU controller is fixedly connected to the housing and is located on the outer wall of the housing.

[0008] The power generation and storage component further includes a mounting base and a connecting rib. The mounting base is fixedly connected to the housing and is located on the outer side wall of the housing. The connecting rib is fixedly connected to the mounting base and the housing.

[0009] The power generation and storage component further includes a partition and a rolling bearing. The partition is fixedly connected to the housing and located on the inner wall of the housing. The rolling bearing is detachably connected to the partition and located on one side of the partition. The rolling bearing is rotatably engaged with the second rotating shaft.

[0010] The speed-increasing component includes a sun gear, a planet carrier, a ring gear, and planetary teeth. The planet carrier is fixedly connected to the housing and located on the inner bottom wall of the housing. The sun gear is detachably connected to the one-way clutch and located at one end of the one-way clutch. The sun gear is rotatably engaged with the planet carrier. The planetary teeth are rotatably connected to the planet carrier and located on one side of the planet carrier. The planetary teeth mesh with the sun gear. The ring gear meshes with the planetary teeth and is located on the outer side wall of the planetary teeth. The second rotating shaft of the ring gear is detachably engaged.

[0011] The mounting components include a top cover, a lower pressure plate, and locking bolts. The top cover is located above the housing. The lower pressure plate is fixedly connected to the top cover and is located on the inner top wall of the top cover. The lower pressure plate is in contact with the battery pack. The locking bolts are threadedly connected to the top cover and the housing in sequence.

[0012] The mounting component further includes a buffer column, which is fixedly connected to the lower pressure plate and located below the lower pressure plate.

[0013] This invention discloses an automotive mechanical energy-saving device. When the vehicle brakes or coasts, power is transmitted through the universal joint flange to the docking flange, driving the first rotating shaft to rotate. At this time, the one-way clutch engages, transmitting power through the speed-increasing component to the second rotating shaft. The high-speed rotation of the second rotating shaft drives the integrated generator to generate electricity, which is stored in the battery pack. When the vehicle accelerates normally or travels at a constant speed, the one-way clutch automatically disengages, interrupting power transmission and stopping the system from generating electricity. This avoids generating additional resistance to vehicle driving. In this way, it solves the problems of limited energy-saving range of engine start-stop technology, inability to recover vehicle coasting kinetic energy, and the inability of the battery to supply power to the display screen for a long time after the gasoline vehicle is turned off, affecting the convenience of use.

The speed-increasing component includes a sun gear 116, a planetary carrier 117, a gear ring 118, and planetary gears 119. The mounting component includes a top cover 120, a lower pressure plate 121, a locking bolt 122, and a buffer post 123. The heat dissipation component includes a heat-absorbing plate 124 and multiple heat dissipation fins 125. The power generation and storage component is connected to the universal joint flange 101; the housing 102 is disposed on one side of the universal joint flange 101; the bearing seat 103 is fixedly connected to the housing 102 and located on one side of the housing 102; the first rotating shaft 104 is rotatably connected to the bearing seat 103 and located on the inner side wall of the bearing seat 103; the docking flange 105 is fixedly connected to the first rotating shaft 104 and located on the outer side wall of the first rotating shaft 104, and the docking flange 105 is detachably coupled to the universal joint flange 101; the one-way clutch 106 is connected to the first rotating shaft 104. Shaft 104 is detached and located at the end of the first rotating shaft 104 away from the docking flange 105. The integrated generator 108 is detached and connected to the housing 102 and located on the inner side wall of the housing 102. The second rotating shaft 107 is detached and connected to the integrated generator 108 and located at the input end of the integrated generator 108. The speed-increasing component is connected to the one-way clutch 106 and the second rotating shaft 107 respectively. The battery pack 109 is disposed on the inner side wall of the housing 102. The mounting component is connected to the housing 102 and the battery pack 109 respectively. In this embodiment, when the vehicle brakes or coasts, power is transmitted to the docking flange 105 via the universal joint flange 101, driving the first rotating shaft 104 to rotate. At this time, the one-way clutch 106 engages, transmitting power to the second rotating shaft 107 via the speed-increasing component. The high-speed rotation of the second rotating shaft 107 drives the integrated generator 108 to generate electricity, which is stored in the battery pack 109. When the vehicle accelerates normally or travels at a constant speed, the one-way clutch 106 automatically disengages, interrupting power transmission and stopping the system from generating electricity, thus avoiding additional resistance to vehicle driving. This solves the problems of limited energy-saving range of engine start-stop technology, inability to recover vehicle coasting kinetic energy, and the inability of the battery to supply power to the display screen for a long time after the fuel vehicle is turned off, affecting the convenience of use. Furthermore, the connecting harness 110 is electrically connected to the battery pack 109 and is located on one side of the battery pack 109, and the automotive-grade MCU controller 111 is fixedly connected to the housing 102 and is located on the outer side wall of the housing 102. In this embodiment, the connecting harness 110 is used to deliver power from the battery pack 109 to the vehicle display screen. The automotive-grade MCU controller 111 is used to detect when the brake pedal is pressed or the accelerator pedal is fully released and the vehicle speed is higher than a predetermined threshold, and prepare to enter the regeneration mode. The one-way clutch 106 automatically engages and works. Furthermore, the mounting base 112 is fixedly connected to the housing 102 and is located on the outer side wall of the housing 102, and the connecting rib 113 is fixedly connected to the mounting base 112 and the housing 102. In this embodiment, the mounting base 112 assists the operator in fixing it into the vehicle with bolts, improving the convenience of installation. The connecting rib 113 can improve the connection strength between the mounting base 112 and the housing 102. Furthermore, the partition 114 is fixedly connected to the housing 102 and is located on the inner side wall of the housing 102. The rolling bearing 115 is detachably connected to the partition 114 and is located on one side of the partition 114. The rolling bearing 115 is rotatably engaged with the second rotating shaft 107. In this embodiment, the partition 114 is used to separate the space of the housing 102, and the rolling bearing 115 is used for the rotation of the second rotating shaft 107 to ensure the stability of the second rotating shaft 107. Furthermore, the planetary carrier 117 is fixedly connected to the housing 102 and located on the inner bottom wall of the housing 102. The sun gear 116 is detachably connected to the one-way clutch 106 and located at one end of the one-way clutch 106. The sun gear 116 is rotatably engaged with the planetary carrier 117. The planetary gear 119 is rotatably connected to the planetary carrier 117 and located on one side of the planetary carrier 117. The planetary gear 119 meshes with the sun gear 116. The gear ring 118 meshes with the planetary gear 119 and is located on the outer side wall of the planetary gear 119. The gear ring 118 is detachably engaged with the second rotating shaft 107. In this embodiment, when the one-way clutch 106 provides power, the power drives the sun gear 116 to rotate. The sun gear 116 drives the planetary gears 119 meshing with it to rotate around their own axis. Since the planet carrier 117 is fixedly connected to the housing 102, the planetary gears 119 cannot revolve around the sun gear, thereby forcibly transmitting power to the gear ring 118 that meshes with all the planetary gears 119 simultaneously. The gear ring 118 outputs power at a speed higher than that of the sun gear 116, driving the second rotating shaft 107 to rotate at high speed, thereby improving the power generation efficiency of the integrated generator 108. Furthermore, the top cover 120 is disposed above the housing 102, the lower pressure plate 121 is fixedly connected to the top cover 120 and located on the inner top wall of the top cover 120, and the lower pressure plate 121 is in contact with the battery pack 109, and the locking bolt 122 is threadedly connected to the top cover 120 and the housing 102 in sequence. In this embodiment, the top cover 120 and the locking bolt 122 work together to seal the housing 102, and the lower pressure plate 121 is used to fix the battery pack 109, improving the ease of installation. Furthermore, the buffer post 123 is fixedly connected to the lower pressure plate 121 and is located below the lower pressure plate 121. In this embodiment, the buffer post 123 is made of rubber, which can alleviate the pressure caused by the downward pressure of the lower pressure plate 121 and avoid affecting the battery pack 109.

[0022] Furthermore, the automotive mechanical energy-saving device also includes a heat dissipation component, which is connected to the top cover 120. The heat dissipation component includes a heat absorption plate 124 and a plurality of heat dissipation fins 125. The heat absorption plate 124 is fixedly connected to the top cover 120 and is located above the top cover 120. The plurality of heat dissipation fins 125 are respectively fixedly connected to the heat absorption plate 124 and are located above the heat absorption plate 124. In this embodiment, the heat-absorbing plate 124 is used to absorb the heat transferred from the top cover 120, and the heat dissipation fins 125 can increase the contact area between the heat-absorbing plate 124 and the air, thereby improving the heat dissipation efficiency.
