Description

Technical Field

[0001] The invention relates to the technical field of new energy vehicles, in particular to a wind wheel for an energy-saving motor of a new energy vehicle. Background Art

[0002] The electric motor of a new energy vehicle is the heart of the power system of a new energy vehicle. It is responsible for converting electrical energy into mechanical energy to drive the vehicle. The electric motor generates torque through electromagnetic action and transmits power to the wheels directly or through the transmission system to achieve acceleration, deceleration and driving of the vehicle. Compared with traditional internal combustion engines, electric motors have high efficiency, low noise, low emissions and good power response characteristics, and are one of the key technologies to achieve the environmental protection and energy-saving goals of new energy vehicles.

[0003] During long-term operation of the motor, energy loss will occur when electrical energy is converted into mechanical energy. These losses are mainly dissipated in the form of heat, causing the motor temperature to rise. In order to ensure the stable operation of the motor and extend its service life, it is necessary to use a wind wheel to dissipate heat and reduce the operating temperature of the motor.

[0004] However, the closer the end of the wind wheel blade on the motor is to the wind wheel axis, the greater the angle of attack is. When the wind wheel starts, the greater the angle of attack is, the greater the starting torque of the wind wheel increases, and when the wind wheel rotates at a low speed, the windward area of ​​the wind wheel increases, allowing the wind wheel to capture more wind energy. However, after the wind wheel rotates at a high speed, an excessively large angle of attack will cause the airflow on the blades to separate, and the airflow will no longer flow smoothly over the blade surface, but will form vortices, reducing the airflow efficiency of the wind wheel, thereby reducing the heat dissipation efficiency of the motor and increasing the power consumption of new energy vehicles.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1-Figure 8 , which is the first embodiment of the present invention, and this embodiment provides a wind wheel for an energy-saving motor of a new energy vehicle. By setting a support component 100 and a blowing component 200, the advantage of such a setting is to avoid the formation of eddy currents, prevent the reduction of the air flow efficiency of the wind wheel, improve the heat dissipation efficiency of the motor, and increase the energy-saving effect of the new energy vehicle.

[0032] Specifically, the support assembly 100 includes a first tray 101 and a second tray 102 arranged on the first tray 101, wherein a plurality of connecting rods are arranged between the first tray 101 and the second tray 102; and the blowing assembly 200 includes a wind-lifting member 201 arranged on the connecting rod, wherein the same connecting block 202 is arranged between the two wind-lifting members 201.

[0033] Among them, a transmission rod fixedly connected to the output end of the motor is provided at the axis center of the second tray 102. When the airflow in the high-pressure area generated in the middle of the first tray 101 and the second tray 102 moves to the low-pressure area around the support assembly 100, the blowing assembly 200 will not block the blowing of the airflow.

[0034] In summary, by setting up the support component 100 and the blowing component 200, the starting motor drives the support component 100 to rotate at a low speed, and a high-pressure area is formed at the axis of the support component 100 to drive the airflow to blow around the support component 100. When the support component 100 gradually speeds up, the wind-raising component 201 gradually deflects around the connecting rod away from the axis of the support component 100 under the action of centrifugal force, thereby gradually reducing the angle of attack. The advantage of such a setting is to avoid the formation of vortices, prevent the reduction of the airflow efficiency of the wind wheel, improve the heat dissipation efficiency of the motor, and increase the energy-saving effect of new energy vehicles.

[0035] Example 2

[0036] Reference Figure 1-Figure 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that a wind-lifting member 201 is provided. The advantage of such a provision is that eddy currents can be avoided, the airflow efficiency of the wind wheel can be prevented from being reduced, the heat dissipation efficiency of the motor can be improved, and the energy-saving effect of the new energy vehicle can be increased. Moreover, the connecting block 202 enables the wind-lifting member 201 to deflect uniformly at the same time and the same rotation speed of the support assembly 100, thereby avoiding inconsistent deflection speeds between several wind-lifting members 201, resulting in unbalanced rotation of the support assembly 100, and thereby preventing the support assembly 100 from increasing the load and reducing the service life.

[0037] Specifically, a plurality of ventilation holes are provided on the second tray 102, a plurality of connecting rods are evenly arranged in a circle around the axis of the first tray 101, and the wind-raising member 201 includes a blade 201a rotatably sleeved with the connecting rod, and a torsion spring is provided between the blade 201a and the connecting rod.

[0038] The ends of the blades 201a are in contact with the first tray 101 and the second tray 102. Normally, the ends of the blades 201a close to the axis of the first tray 101 point to the axis of the first tray 101, and concave and convex surfaces are provided near the blades 201a.

[0039] The concave surface faces the direction of rotation of the support assembly 100, and the convex surface faces the opposite direction of rotation of the support assembly 100. A coupling plate 201b is provided at one end of the blade 201a away from the axis of the first tray 101, wherein the same connecting block 202 is provided between the two coupling plates 201b.

[0040] The connecting block 202 includes a first rotating rod 202c and a second rotating rod 202d. One end of the connecting plate 201b away from the blade 201a is rotatably connected to the second rotating rod 202d. One end of the other connecting plate 201b away from the blade 201a is rotatably connected to the first rotating rod 202c.

[0041] The second rotating rod 202d is close to the B end of the connecting block 202, and the first rotating rod 202c is close to the A end of the connecting block 202. The distance between the two sides of the connecting block 202 gradually increases from the A end to the B end.

[0042] Among them, a number of ventilation holes are opened on the second tray 102, so that the hot air can flow out through the ventilation holes between the first tray 101 and the second tray 102. A number of connecting rods are evenly arranged in a circle around the axis of the first tray 101, so that the hot air can be evenly blown out from the support assembly 100 to the surroundings. A torsion spring is arranged between the blade 201a and the connecting rod, so that the end of the blade 201a close to the axis of the first tray 101 under normal conditions points to the axis of the first tray 101, so as to obtain a larger starting torque when the support assembly 100 just rotates.

[0043] The ends of the blade 201a both collide with the first tray 101 and the second tray 102 to avoid a large gap between the blade 201a and the first tray 101 and the second tray 102, so that the airflow flows out from the gap, the aerodynamic layout of the blade 201a is reduced, and the concave surface faces the direction of rotation of the support assembly 100 to facilitate the formation of a thrust surface, and the convex surface faces the opposite direction of rotation of the support assembly 100 to facilitate the formation of a suction surface. The same connecting block 202 is arranged between the two coupling plates 201b to facilitate the unified deflection of several blades 201a and prevent the deflection speed of individual blades 201a from being inconsistent, which causes unbalanced rotation of the support assembly 100.

[0044] The first rotating rod 202c is close to the A end of the connecting block 202, and the distance between the two sides of the connecting block 202 gradually increases from the A end to the B end, so that the L-shaped fixing rod 302b can be inserted deeper under the action of centrifugal force, thereby providing more friction to limit the blade 201a.

[0045] The support assembly 100 and the wind-raising member 200 are covered with a soundproof cover to avoid noise.

[0046] In summary, by setting the wind lifting member 201, when the starting motor drives the support assembly 100 to start rotating, due to the aerodynamic layout of the wind lifting member 201 between the first tray 101 and the second tray 102, a high-pressure area is formed at the axis of the support assembly 100, and a low-pressure area is formed around the support assembly 100. Hot air flows out from between the first tray 101 and the second tray 102 through the ventilation holes and blows to the surroundings of the support assembly 100 for discharge. At the same time, the end of the blade 201a close to the axis of 100 initially points to the axis of the support assembly 100, providing a large starting torque. As the motor accelerates, the speed of the support assembly 100 gradually increases, which causes the blade 201a to rotate in the centrifugal force. Under the action of force, the wind lifting member 201 gradually deflects around the axis of the connecting rod toward the axis of the supporting assembly 100, and the blade 201a then drives the coupling plate 201b to move the B end of the connecting block 202 toward the A end of the connecting block 202. The advantage of this arrangement is to avoid the formation of vortices, prevent the reduction of the airflow efficiency of the wind wheel, improve the heat dissipation efficiency of the motor, and increase the energy-saving effect of new energy vehicles. In addition, the connecting block 202 makes the wind lifting member 201 deflect uniformly at the same time and the same speed of the supporting assembly 100, avoiding inconsistent deflection speeds between several wind lifting members 201, resulting in unbalanced rotation of the supporting assembly 100, thereby preventing the supporting assembly 100 from increasing the load and reducing the service life.

[0047] Example 3

[0048] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that an L-shaped fixing rod 302b and a resistance increasing groove 202b are provided. The advantage of such a provision is that when there is dirt on the wind-lifting member 201 and the L-shaped fixing rod 302b cannot limit the connecting block 202, the L-shaped fixing rod 302b hits the inner wall of the resistance increasing groove 202b to generate vibration and cause the dirt to fall off, thereby further improving the use efficiency and service life of the wind wheel.

[0049] Specifically, the connecting block 202 is also provided with a placement groove 202a and a resistance-increasing groove 202b connected to the placement groove 202a, and the top inner wall and the bottom inner wall of the resistance-increasing groove 202b are both provided with a plurality of protrusions 202e. A limiting assembly 300 is provided on the first tray 101, and the limiting assembly 300 includes a plurality of telescopic rods 301 provided on the first tray 101.

[0050] A plurality of telescopic rods 301 are evenly arranged in a circle around the axis of the first pallet 101, the telescopic rods 301 include a stabilizing rod fixedly connected to the first pallet 101, an end of the stabilizing rod away from the first pallet 101 is slidably sleeved with a sliding rod, a resistance member 302 is provided on the sliding rod, and a spring 303 is provided at one end of the sliding rod away from the stabilizing rod, and one end of the spring 303 away from the sliding rod is fixedly connected to the first pallet 101.

[0051] The resistance member 302 is close to the A end of the connecting block 202, and the resistance member 302 includes an L-shaped fixing rod 302b with a bottom end arranged on the sliding rod, the top of the L-shaped fixing rod 302b gradually tilts downward from one end of the L-shaped fixing rod 302b close to the stabilizing rod to the end away from the stabilizing rod, and the bottom of the L-shaped fixing rod 302b gradually tilts upward from one end of the L-shaped fixing rod 302b close to the stabilizing rod to the end away from the stabilizing rod, and rubber sheets 302a are arranged on the top and bottom of the L-shaped fixing rod 302b.

[0052] Normally, the end of the L-shaped fixing rod 302b away from the stabilizing rod is inserted into the placement groove 202a, the top and bottom of the resistance increasing groove 202b are both adapted to the L-shaped fixing rod 302b, and the distance between the two sides of the resistance increasing groove 202b gradually increases from the A end to the B end.

[0053] Among them, the connecting block 202 is also provided with a seating groove 202a and a resistance-increasing groove 202b connected to the seating groove 202a. The resistance-increasing groove 202b facilitates the insertion and limiting of the resistance member 302. The top inner wall and the bottom inner wall of the resistance-increasing groove 202b are both provided with a plurality of protrusions 202e. The protrusions 202e facilitate further interference with the resistance member 302 to increase friction.

[0054] A spring 303 is provided at one end of the sliding rod away from the stabilizing rod. Under normal conditions, the spring 303 pushes the L-shaped fixing rod 302b to contact the stabilizing rod under the action of elastic potential energy.

[0055] The top of the L-shaped fixing rod 302b gradually slopes downward from the end of the L-shaped fixing rod 302b close to the stabilizing rod to the end away from the stabilizing rod, and the bottom of the L-shaped fixing rod 302b gradually slopes upward from the end of the L-shaped fixing rod 302b close to the stabilizing rod to the end away from the stabilizing rod, which not only facilitates the insertion of the L-shaped fixing rod 302b, but also when there is dirt on the blade 201a, causing the wind-raising member 201 and the connecting block 202 to shake due to imbalance under the rotation of the support assembly 100, the rubber The downward-inclined top and upward-inclined bottom of the sheet 302a will create gaps and collisions with the bottom inner walls and bottom inner walls of the resistance-increasing groove 202b, and then the L-shaped fixing rod 302b will vibrate the connecting block 202 and the wind-lifting member 201, causing the dirt on the wind-lifting member 201 to fall off. The top and bottom of the L-shaped fixing rod 302b are both provided with rubber sheets 302a, which increase the friction between the top and bottom of the rubber sheet 302b and the top inner walls and bottom inner walls of the resistance-increasing groove 202b.

[0056] The distance between the two sides of the resistance increasing groove 202b gradually increases from the A end to the B end, so that when the centrifugal force of the support assembly 100 gradually increases, the rubber sheet 302b gradually approaches the connecting block 202, and the connecting block 202 also gradually approaches the rubber sheet 302b, so that the rubber sheet 302b is gradually inserted deeper, thereby gradually increasing the friction force, so that when there is dirt on the connecting block 202 and the wind-lifting member 201, relative stillness is generated.

[0057] In summary, by providing the L-shaped fixing rod 302b and the resistance increasing groove 202b, initially the L-shaped fixing rod 302b is inserted into the placement groove 202a and does not conflict with the inner wall of the placement groove 202a. As the rotation speed of the support assembly 100 gradually increases, the centrifugal force gradually increases. Therefore, the connecting block 202 moves toward the A end, and the telescopic rod 301 and the conflicting member 302 also gradually compress the spring 303 under the action of the centrifugal force, causing the spring 303 to produce elastic deformation, thereby causing the sliding rod to slide in the direction away from the stable rice, driving the L-shaped fixing rod 302b to move toward the connecting block 202, and then the L-shaped fixing rod 302b is removed from the placement groove 202a. Insert it into the resistance increasing groove 202b until the centrifugal force at this time makes the end of the L-shaped fixing rod 302b collide with the inner wall of the end of the resistance increasing groove 202b, and the rubber sheet 302a at the top of the L-shaped fixing rod 302b and the rubber sheet 302a at the bottom of the L-shaped fixing rod 302b respectively collide with the protrusion 202e of the inner wall of the top of the resistance increasing groove 202b and the protrusion 202e of the inner wall of the bottom of the resistance increasing groove 202b to limit the position, thereby preventing dirt from being present on the wind lifting member 201 and the connecting block 202, which will cause the mass of the wind lifting member 201 and the connecting block 202 to be unbalanced, thereby causing the support assembly 100 to rotate unbalancedly, resulting in an increase in the load of the support assembly 100 and a reduction in the service life.

[0058] As the centrifugal force gradually increases, the connecting block 202 moves toward the A end again and gets closer to the L-shaped fixing rod 302b, while the L-shaped fixing rod 302b also moves further away from the stabilizing rod under the action of the centrifugal force. Therefore, the L-shaped fixing rod 302b is inserted deeper into the resistance increasing groove 202b, so that the rubber sheet 302a at the top of the L-shaped fixing rod 302b and the rubber sheet 302a at the bottom of the L-shaped fixing rod 302b increase the contact area with the protrusion 202e on the top inner wall of the resistance increasing groove 202b and the protrusion 202e on the bottom inner wall of the resistance increasing groove 202b, thereby increasing the friction force and enhancing the limiting force of the L-shaped fixing rod 302b on the connecting block 202 until the end of the L-shaped fixing rod 302b contacts the inner wall of the end of the resistance increasing groove 202b.

[0059] When the weight of the dirt on the wind-lifting member 201 causes the wind-lifting member 201 to slightly shake when the support assembly 100 rotates, the connecting block 202 is further driven to shake. Since the top of the L-shaped fixing rod 302b is tilted downward and the bottom is tilted upward, after the L-shaped fixing rod 302b is inserted into the resistance-increasing groove 202b under the action of centrifugal force, there is a gap between the top and bottom of the L-shaped fixing rod 302b and the top inner wall and the bottom inner wall of the resistance-increasing groove 202b, so that when the connecting block 202 shakes, the top inner wall and the bottom inner wall of the resistance-increasing groove 202b are pressed against the L-shaped fixing rod 302b. The L-shaped fixing rod 302b collides with the connecting block 202, thereby generating vibrations on the connecting block 202 and the wind-lifting member 201, causing the dirt on the wind-lifting member 201 to fall off, thereby restoring the balance of the support assembly 100. As the rotation speed of the support assembly 100 increases, the centrifugal force increases, and the above operation is repeated. The advantage of such a setting is that when there is dirt on the wind-lifting member 201 and the connecting block 202 cannot be limited by the L-shaped fixing rod 302b, the L-shaped fixing rod 302b collides with the inner wall of the resistance-increasing groove 202b to generate vibrations to cause the dirt to fall off, thereby further improving the use efficiency and service life of the wind wheel.
