[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) When a new energy vehicle is running, its internal drive motor will generate a large amount of heat. The hot air flow moves with the blowing of the dust removal fan and passes through the insulation box, heating the gas inside the heat collecting tube and storing hot air on one side of the insulation box. When unlocking the vehicle in cold weather, if the temperature sensor detects that the temperature inside the drive housing is too low, the vacuum pump extracts part of the hot air stored in the insulation box and injects it into the drive housing to preheat the inside of the drive housing, thereby preventing the vehicle from being unable to start due to the low temperature inside the drive housing. At the same time, only part of the hot air is injected to prevent the user from just taking items without driving the vehicle. When the vehicle is officially started, the vacuum pump injects most of the hot air stored in the insulation box into the drive housing, allowing the inside of the drive housing to quickly preheat and reduce the temperature. The waiting time of users is reduced, and the heat generated by the driving motor is used to realize cold start of vehicles in cold weather, ensure the normal driving of the vehicle, improve the driving experience of users, and achieve energy-saving effects. In hot weather, cold start is not required. At this time, the battery valve is opened, and the hot air enters the mobile pipe and moves. As the gas continues to expand due to heat, the mobile plug plate is pushed to move, causing the mobile frame to move. When the mobile plug plate moves to the vent pipe, the hot air will be discharged through the vent pipe, and the mobile plug plate will be reset under the push of the mobile spring, so that the mobile frame continues to move, driving the rotating disk to rotate continuously, and the rotating disk drives the follower shaft to rotate, so that the coil rotates. According to the principle of electromagnetic induction, the coil continuously cuts the magnetic field to generate current, thereby improving energy utilization.

[0016] (2) After the new energy vehicle starts running, the drive motor will continue to work and generate heat. The rotation of the drive motor will drive the drive shaft to rotate, so that the dust removal fan will rotate accordingly. The dust removal fan can quickly discharge the heat inside the drive housing through several air outlets, and at the same time discharge the dust inside the drive housing. However, since the specific temperature of the gas entering the drive housing is uncertain, if the gas entering the drive housing is also high temperature, it will not have a heat dissipation effect on the drive motor. Since the drive housing is located inside the new energy vehicle, most of the gas entering the drive housing has a certain temperature, which has a limited heat dissipation effect on the drive motor. The gas entering the driving housing in the device enters through the spiral curved tube, which is located inside the annular liquid cavity, and the annular liquid cavity is filled with coolant, so that the spiral curved tube is immersed in the coolant, thereby cooling the gas entering the driving housing. The special design of the spiral curved tube increases the contact time between the gas and the coolant, improves the gas cooling effect, avoids the high temperature of the gas entering the driving housing, thereby improving the heat dissipation effect of the driving motor, and avoids the heat generated by the new energy vehicle driving device during use. The device cannot be dissipated in time, resulting in a shortened service life of the driving device, which greatly increases the cost loss;

[0017] (3) When the new energy vehicle needs to brake at high speed, the driver will step on the foot brake to the bottom, thereby controlling the built-in micro battery to power the annular electromagnetic block through the console of the new energy vehicle. After power is turned on, the annular electromagnetic block generates a repulsive force on the magnetic sheet, thereby causing the gear block to slide out of the mounting groove, so that the connecting piece and the driving gear engage. Since the drive shaft continues to rotate under the inertia of the vehicle, the drive shaft passes through the connecting piece and the driving gear to make the generator work, thereby increasing the speed of the generator shaft and generating electricity. The inertia of the vehicle when decelerating is used to generate electricity, thereby realizing kinetic energy recovery and improving the energy-saving effect of the drive device for the new energy vehicle.

DETAILED DESCRIPTION

[0026] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] Please refer to the attached Figure 1-3The present invention provides a technical solution: an energy-saving driving device for a new energy vehicle, comprising a driving housing 1, a cooling box 2 is connected to one side of the driving housing 1, an annular liquid chamber 21 is arranged inside the cooling box 2, a driving shaft 11 rotatably connected to the cooling box 2 is arranged at the center of the annular liquid chamber 21, a driving motor 12 and a generator 15 are arranged inside the driving housing 1, an output end of the driving motor 12 is connected to the axis of the driving shaft 11, a dust removal fan 13 and a driving gear 14 are installed on the driving shaft 11, and the dust removal fan 13 and the driving gear 14 are located inside the driving housing 1, and a plurality of A spiral curved tube 22, each of which has an air inlet 23 and an exhaust port 24 at both ends, the air inlet 23 and the exhaust port 24 both pass through the cooling box 2, and the exhaust port 24 extends into the interior of the drive housing 1, a plurality of air outlets 19 are provided on the other side of the drive housing 1, an annular cavity 25 is provided inside the drive housing 1, coolant is provided inside the annular liquid cavity 21 and the annular cavity 25, and the annular liquid cavity 21 and the annular cavity 25 are connected to the automobile coolant circulation system, and dust filters 5 are installed on the plurality of air outlets 19 and the air inlet 23, through which dust can be prevented from entering the interior of the drive housing 1.

[0030] When the new energy vehicle starts running, the drive motor 12 will continue to work and generate heat. Due to the rotation of the drive motor 12, the drive shaft 11 will be driven to rotate, so that the dust removal fan 13 will rotate accordingly. The dust removal fan 13 can quickly discharge the heat inside the drive housing 1 through a plurality of air outlets 19, and at the same time discharge the dust inside the drive housing 1. However, since the specific temperature of the gas entering the drive housing 1 is uncertain, if the gas entering the drive housing 1 is also high temperature, it cannot have a heat dissipation effect on the drive motor 12. Since the drive housing 1 is located inside the new energy vehicle, most of the gas entering the drive housing 1 has a certain temperature, and the heat dissipation effect on the drive motor 12 is poor. The gas inside the body 1 enters through the spiral curved tube 22, and the spiral curved tube 22 is located inside the annular liquid cavity 21. The annular liquid cavity 21 is filled with coolant, so that the spiral curved tube 22 is immersed in the coolant, thereby cooling the gas entering the drive housing 1. The special design of the spiral curved tube 22 increases the contact time between the gas and the coolant, improves the gas cooling effect, and avoids the gas entering the drive housing 1 having a high temperature, thereby improving the heat dissipation effect of the drive motor 12. At the same time, the coolant inside the annular liquid cavity 21 can also improve the effective heat dissipation of the drive housing 1, avoiding the heat generated by the new energy vehicle drive device during use. The heat cannot be dissipated in time, resulting in a shortened service life of the drive device, which greatly increases the cost loss.

[0031] Please refer to the attached Figure 1-6, a plurality of heat preservation boxes 4 are embedded on the side wall of the driving housing 1, a heat preservation plate 41 is built in the middle of the heat preservation box 4, a heat collecting pipe 42 is embedded on the side of the heat preservation plate 41 facing the inside of the driving housing 1, a plurality of air intake check valves 44 and exhaust check valves 43 are respectively provided on both sides of the heat collecting pipe 42, a plurality of the air intake check valves 44 are installed on the side wall of the heat preservation box 4 facing the driving motor 12, a plurality of the exhaust check valves 43 are installed on the other side wall of the heat preservation box 4, an exhaust check valve 47 and a connecting pipe 45 installed on the side wall of the heat preservation box 4 are provided on the other side of the heat preservation plate 41, the other end of the connecting pipe 45 is connected to the driving housing 1, and the connecting port of the connecting pipe 45 and the driving housing 1 is located between the driving motor 12 and the dust removal fan 13, an exhaust pump 46 is provided on the connecting pipe 45, and the exhaust pump 46 and the built-in micro battery 18 are electrically connected. Since the electric energy of the built-in micro battery 18 is the energy generated by the deceleration of the new energy vehicle, the use of the vacuum pump 46 will not produce additional energy loss. A mounting frame 10 is provided at the lower end of the drive motor 12, and a support frame 16 is provided outside the generator 15. An inverter 17 and a built-in micro battery 18 are provided inside the support frame 16. The built-in micro battery 18 is electrically connected to the vehicle battery. The electric vehicle uses an on-board DC power supply (rechargeable battery) as a power source. The inverter 17 converts the DC power of the on-board DC power supply into AC power and then provides it to the drive motor 12. The drive shaft 11 transmits the power to the gearbox and then drives the wheels to travel. A temperature sensor 48 is installed on the mounting frame 10. The temperature sensor 48 is used to detect the internal temperature of the drive housing 1, and the temperature sensor 48 is connected to the vehicle system.

[0032] A charging box 6 is installed outside each of the insulation boxes 4. A solenoid valve 61 is provided at the connection between the charging box 6 and the insulation box 4. One side of the solenoid valve 61 is connected to a charging component located inside the charging box 6. The charging component includes a movable pipe 62. A movable plug plate 63 is sliding inside the movable pipe 62. A movable spring 64 and a movable frame 65 are connected to the movable plug plate 63 away from the solenoid valve 61. A vent pipe 66 is connected to one side of the movable pipe 62. A rotating disk 67 is installed inside the charging box 6. A pull rod 68 is installed at an eccentric position on one side of the rotating disk 67. A connecting rod is rotatably connected between the pull rod 68 and the movable frame 65. A follower shaft 7 is installed on the axis of the other side of the rotating disk 67. A coil 71 is installed on the follower shaft 7, and the coil 71 is in a rectangular frame shape. A magnet 72 is provided outside the coil 71.

[0033] When the new energy vehicle is running, its internal drive motor 12 will generate a large amount of heat and move with the blowing of the dust removal fan 13. The hot air flow will enter the insulation box 4 through the air intake check valve 44. As the gas inside the insulation box 4 is continuously added, part of the gas will be discharged from the exhaust check valve 43. The heat collecting pipe 42 will absorb the heat of the hot air flow, so that the gas inside the heat collecting pipe 42 is heated, and the hot air is stored on one side of the insulation box 4. When used in cold weather, unlock the vehicle. If the temperature sensor 48 detects that the temperature inside the drive housing 1 is too low, the air pump 46 extracts part of the hot air stored in the insulation box 4 and injects it into the drive housing 1, so that the inside of the drive housing 1 is preheated to avoid the vehicle being unable to be officially started due to the internal temperature of the drive housing 1 being too low. At the same time, only part of the hot air is injected to avoid the situation where the user only takes items without driving. When the vehicle is officially started, the air pump 46 injects most of the hot air stored in the insulation box 4 into the heat preservation box 4. The heat generated by the driving motor 12 is used to start the vehicle in cold weather, thereby ensuring the normal driving of the vehicle, improving the driving experience of the user, and reducing energy consumption. In hot weather, there is no need for a cold start. At this time, the solenoid valve 61 is opened, and the hot air enters the moving pipe 62 and moves. As the gas continues to expand due to heat, the moving plug plate 63 is pushed to move, causing the moving frame 65 to move. When the moving plug plate 63 moves to the vent pipe 66, the hot air will be discharged through the vent pipe 66. The moving plug plate 63 is reset under the push of the moving spring 64, so that the moving frame 65 continues to move, driving the rotating disk 67 to rotate continuously. The rotating disk 67 drives the follower shaft 7 to rotate, causing the coil 71 to rotate. According to the principle of electromagnetic induction, the coil 71 continuously cuts the magnetic field to generate current, thereby improving the utilization rate of energy.

[0034] Please refer to the attached Figure 1-6A connector 3 is installed at the output end of the generator 15, and the connector 3 includes a circular ring disk 31 installed at the output end of the generator 15, and a circular ring electromagnetic block 38 is installed inside the circular ring disk 31. The circular ring electromagnetic block 38 is provided with a plurality of placement grooves 32 outside, and the plurality of placement grooves 32 are equidistantly distributed on the circular ring disk 31, and an insulating slide 33 is slid inside each of the placement grooves 32, and a magnetic sheet 34 is connected to the side of the insulating slide 33 facing the circular ring electromagnetic block 38, and a tooth block 35 and a reset spring 36 are connected to the other side of the insulating slide 33, and the other end of the reset spring 36 is installed at the notch of the placement groove 32, and a limit ring 37 is installed at the notch of the placement groove 32, and the magnetic sheet 34 and the circular ring electromagnetic block 38 after power is supplied are magnetically repelled, and when the circular ring electromagnetic block 38 is powered on, the tooth block 35 slides out of the placement groove 32, and the connector 3 is meshed with the driving gear 14. The annular electromagnetic block 38 is electrically connected to the built-in micro battery 18. Since the electric energy of the built-in micro battery 18 is the energy generated by decelerating the new energy vehicle, the use of the annular electromagnetic block 38 will not cause additional energy loss.

[0035] When the new energy vehicle needs to brake at high speed, the driver will step on the foot brake to the bottom, thereby controlling the built-in micro battery 18 through the console of the new energy vehicle to power the annular electromagnetic block 38. After being energized, the annular electromagnetic block 38 generates a repulsive force on the magnetic sheet 34, so that the magnetic sheet 34 pushes the insulating slide 33 to slide inside the mounting groove 32, and the reset spring 36 contracts until the insulating slide 33 and the limit ring 37 contact and stop moving. At this time, the tooth block 35 slides out of the mounting groove 32, so that the connecting member 3 and the driving gear 14 are engaged. Since the driving shaft 11 continues to rotate under the action of the inertia of the vehicle, the driving shaft 11 passes through the connecting member 3 and the driving gear 14 to make the generator 15 work, thereby increasing the speed of the generator 15 shaft and generating electricity. The inertia of the vehicle when decelerating is used to generate electricity, thereby realizing kinetic energy recovery and improving the energy-saving effect of the driving device for the new energy vehicle.

[0036] The specific operation process of the present invention is as follows:

[0037] When the new energy vehicle starts running, the drive motor 12 will continue to work and generate heat. Due to the rotation of the drive motor 12, the drive shaft 11 will be driven to rotate, so that the dust removal fan 13 rotates accordingly, so that the outside air enters the drive housing 1 through the spiral curved tube 22. The spiral curved tube 22 is located inside the annular liquid cavity 21. The annular liquid cavity 21 is filled with coolant. The spiral curved tube 22 is immersed in the coolant, so that the gas entering the drive housing 1 is cooled. The special design of the spiral curved tube 22 makes the contact between the gas and the coolant The time is increased, the gas cooling effect is improved, and the gas entering the driving housing 1 is prevented from having high temperature, thereby improving the heat dissipation effect of the driving motor 12. The driving motor 12 generates a large amount of heat and moves with the blowing of the dust removal fan 13. The hot air flow will enter the insulation box 4 through the air inlet check valve 44. As the gas inside the insulation box 4 is continuously added, part of the gas will be discharged from the exhaust check valve 43, and then quickly discharged through a number of outlets 19, and at the same time, the dust inside the driving housing 1 will be discharged. When the exhaust inside the driving housing 1, the heat collector The tube 42 absorbs the heat of the hot air flow, so that the gas inside the heat collecting tube 42 is heated, and the heat is stored on one side of the heat preservation box 4. The stored heat is used for cold car starting in cold weather, or for energy conversion and utilization in hot weather. When the new energy vehicle needs to brake at high speed, the driver will step on the foot brake to the bottom, so that the built-in micro battery 18 is controlled by the console of the new energy vehicle to supply power to the annular electromagnetic block 38. After the power is turned on, the annular electromagnetic block 38 generates a repulsive force on the magnetic sheet 34, so that the magnetic sheet 34 pushes the insulating slide plate 33 to be placed The groove 32 slides inside and the return spring 36 contracts until the insulating slide plate 33 and the limit ring 37 contact and stop moving. At this time, the tooth block 35 slides out of the placement groove 32, so that the connecting piece 3 and the driving gear 14 are engaged. Since the driving shaft 11 continues to rotate under the action of the inertia of the vehicle, the driving shaft 11 passes through the connecting piece 3 and the driving gear 14 to enable the generator 15 to work, thereby increasing the speed of the generator 15 shaft to generate electricity. The inertia of the vehicle when decelerating is used to generate electricity, kinetic energy recovery is achieved, and the energy-saving effect of the drive device for the new energy vehicle is improved.

[0038] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
