Description

Technical Field

[0001] The present invention relates to the technical field of automotive air conditioner blowers, and particularly to a low-noise blower with a vibration isolation and buffering mechanism. Background Art

[0002] The main function of an automotive air conditioner blower is to drive the fan blades to rotate through an electric motor, and send the air cooled by an evaporator or heated by a heater into the vehicle interior, thereby realizing the circulation and temperature adjustment of the air in the vehicle interior. Automotive air conditioner blowers usually adopt a centrifugal design. Its working principle is that the rotation of the electric motor drives the internal fan blades, so that the air is sucked in from the air inlet, and is discharged from the air outlet after being pushed by the fan blades, forming an air flow. Among them, by arranging a buffering mechanism between the outer shell and the motor on the blower, the vibration generated during the operation of the motor can be reduced from being transmitted to the outer shell.

[0003] In the device for vibration-isolatingly holding an electric motor with Chinese Patent Application No. 200780048856.4, in this invention, the electric motor has a pole housing (3) and a machine flange, and at least one vibration isolation element (7) is arranged between them. This element abuts on the contact surface (11) of the pole housing (3) and / or the motor flange (4), and at least partially has a spherical-like structural shape. It is stipulated that the contact surface (11) is designed to be shape-matched to the spherical-like structural shape, and when the vibration reduction is good, a reliable fixation is ensured while largely avoiding the sinking of the electric motor relative to the motor flange and / or the housing.

[0004] In current automotive air conditioner blowers, the blades of the fan are integrally fixed. When cleaning the fan blades, the gaps between the blades are not convenient for flushing and wiping, which affects the cleaning effect of the fan blades. Moreover, in the above-mentioned comparative document, the spherical-like buffer structure shape has a relatively weak connection at the installation part with the motor housing, the installation is unstable, and the spherical buffer structure shape is prone to shift to one side during use, affecting the buffer and shock absorption effect.

When the rotating member is at the bottommost end of the moving groove, the receiving blade is fixed to the fan blade base through the fixing column thereon. When the rotating member is at the topmost end of the moving groove, the blade is released from fixation, so that the blade can be manually rotated, facilitating the switching between the fixed state and the rotatable state of the blade. And when rotating the blade, through the transmission of the transmission belt among the blades, the blades rotate synchronously in the same direction, adjusting the angles of the side walls at the gaps between the blades, facilitating the cleaning of the gaps between the blades, enabling the blades to be cleaned more thoroughly, and reducing the residue of stains;

[0022] (2) In this solution, by setting the vibration isolation and buffering mechanism, the buffer rubber is clamped on the clamping bracket through the clamping groove, increasing the contact area at the connection between the buffer rubber and the clamping bracket. Compared with the traditional spherical vibration buffering structure, the buffer rubber can be more stably installed on the clamping bracket. By providing notch openings at both ends of the outer wall of the buffer rubber, two effective buffer and shock damping points are respectively formed at both ends of the buffer rubber, increasing the buffering performance of the buffer rubber and enhancing the buffering effect. By providing the first limiting plate and the second limiting plate in the lower housing and the upper housing, when the buffer rubber is installed, the limiting grooves at both ends of the buffer rubber can be respectively clamped on the first limiting plate and the second limiting plate, making it not easy for the buffer rubber to deviate in angle during installation and use, and further increasing the buffer and shock damping effect of the buffer rubber;

[0023] (3) In this solution, the fixed ring is inserted into the top of the mounting ring, and the fixing cylinder on the fixed ring is aligned with the fixing column at the top of the blade. The fixing column is inserted into the corresponding fixing cylinder inside to fix the top of the blade. At this time, the first threaded hole on the mounting ring and the second threaded hole on the fixed ring are aligned, and the fixed ring is fixed to the top of the mounting ring through screws. At this time, the fixed ring presses the blade downward, so that the fixing column at the bottom end of the fixed ring is inserted into the corresponding fixing hole, facilitating the fixation of the blade;

[0024] (4) In this solution, by setting up the installation frame, the second spring in the installation frame supports the moving block to move towards the inner surface of the transmission belt, so that the roller is supported on the corresponding inner surface of the transmission belt, making the contact between the transmission belt and the outer wall of the corresponding transmission disc closer, reducing the loosening of the transmission belt, and enabling the transmission belt to transmit better.

The vibration isolation and buffering mechanism uses the buffer rubber 103 therein to reduce the vibration generated by the motor 1 in the blower during operation from being transmitted to the lower housing 2 and the upper housing 204, thereby improving the NVH effect of the blower when operating on the air conditioner; by setting the fan blade mounting mechanism, the top end of the blade 310 in the fan blade mounting mechanism is installed at the bottom of the mounting ring 401 through the limiting rod 311, and the bottom end of the blade 310 is installed on the fan blade base 3 through the rotating part 307. When the rotating part 307 is at the bottom end of the moving groove 304, the blade 310 is fixed to the fan blade base 3 through the fixing column 3091 thereon. When the rotating part 307 is at the top end of the moving groove 304, the blade 310 is released from fixation, enabling the blade 310 to be manually rotated, facilitating the switching between the fixed and rotatable states of the blade 310. And when rotating the blade 310, the transmission between the blades 310 through the transmission belt 406 makes the blades 310 rotate synchronously and in the same direction, adjusting the angle of the side walls at the gaps between the blades 310, facilitating the cleaning of the gaps between the blades 310, enabling the blades 310 to be cleaned more thoroughly, and reducing the residue of stains.

[0041] In some embodiments, refer to Figure 7 , Figure 8 , Figure 9 , Figure 10, the blade mounting mechanism includes a blade base 3, a plurality of mounting grooves 301, a plurality of fixing grooves 302, a plurality of fixing holes 303, a moving groove 304, a moving column 305, a rotating member 307, a connecting plate 308, a plurality of fixing clamping plates 3081, a connecting plate 309, a plurality of fixing columns 3091, a blade 310, a plurality of connecting frames 4, a mounting ring 401, a plurality of rotating columns 404, a plurality of transmission discs 405 and a plurality of transmission belts 406. The blade base 3 is fixedly installed at one end of the mounting shaft 107. A plurality of mounting grooves 301 and fixing holes 303 are opened at the top of the blade base 3. A plurality of fixing grooves 302 are opened at the bottom end of the groove wall of the mounting groove 301. The moving groove 304 is opened at the bottom end of the groove wall of the mounting groove 301. The moving column 305 is fixedly installed at the bottom end of the groove wall of the moving groove 304. The rotating member 307 is slidably installed on the outer wall of the moving column 305. The rotating member 307 is slidably installed on the groove wall of the moving groove 304.

A plurality of connecting frames 4 are fixedly installed at the top of the blade base 3. The mounting ring 401 is fixedly installed at one end of the connecting frame 4. A plurality of rotating columns 404 are fixedly installed at the bottom end of the inner wall of the mounting ring 401. Two transmission discs 405 are fixedly installed on the outer wall of the rotating column 404. The transmission belt 406 is installed on the outer wall of the corresponding transmission disc 405 on the corresponding rotating column 404; the rotating columns 404 form a circle inside the mounting ring 401. There are two transmission discs 405 on the rotating column 404. The installation order of the transmission belt 406 between adjacent rotating columns 404 is: in the order of adjacent two top transmission discs 405, adjacent two bottom transmission discs 405, adjacent two top transmission discs 405, adjacent two bottom transmission discs 405... in sequence, so that when one blade 310 rotates, it drives other blades 310 to rotate synchronously. After removing the fixing ring 5, the first spring 306 rebounds to support the upward movement of the rotating member 307, thereby driving the upward movement of the blade 310. The fixing column 3091 at the bottom of the blade 310 disengages from the fixing hole 303, and the fixing clamping plate 3081 at the bottom of the blade 310 disengages from the fixing groove 302, canceling the fixing of the blade 310.

[0042] In some embodiments, refer to Figure 7 , Figure 8, the position of the fixing hole 303 corresponds to the position of the fixing post 3091 at the bottom of the blade 310. The fixing post 3091 at the bottom of the blade 310 is engaged with the corresponding fixing hole 303.

By setting the connection disc 308, when the blade 310 moves downward, the connection disc 308 moves downward, and the fixing clamping plate 3081 moves downward and inserts into the corresponding fixing groove 302, increasing the support pad when the blade 310 is fixed and making the fixing of the blade 310 more stable.

[0043] In some embodiments, referring to FIGS., at the bottom end of the groove wall of the moving groove 304, a first spring 306 is fixedly installed. The first spring 306 is wound around the outer wall of the corresponding moving post 305.

The limiting rod 311 is slidably installed on the inner wall of the sliding hole 407 at the bottom end of the corresponding rotating column 404. The sliding hole 407 and the limiting rod 311 are polygonal. By setting the first spring 306, the blade 310 can be supported to move upward, so that when the fixing ring 5 is removed, the blade 310 can bounce upward. By setting the limiting rod 311 and the sliding hole 407 to be polygonal, when the limiting rod 311 moves in the sliding hole 407, the rotating column 404 can drive the blade 310 to rotate through the limiting rod 311 when rotating.

[0044] In some embodiments, referring to Figure 5 , Figure 6, a fixing ring 5 is provided at the top of the mounting ring 401.

A number of first threaded holes 402 are formed at the top end of the mounting ring 401, and a number of second threaded holes 501 are formed at the top end of the fixing ring 5. The positions of the second threaded holes 501 correspond to those of the first threaded holes 402. Screws are threadedly connected to the inner walls of the corresponding first threaded holes 402 and second threaded holes 501. When fixing the blade 310, the fixing ring 5 is inserted into the top of the mounting ring 401, and the fixed cylinders 502 on the fixing ring 5 are aligned with the fixing posts 3091 at the top of the blade 310. The fixing posts 3091 are inserted into the corresponding fixed cylinders 502 to fix the top of the blade 310. At this time, the first threaded holes 402 on the mounting ring 401 are aligned with the second threaded holes 501 on the fixing ring 5. The fixing ring 5 is fixed to the top of the mounting ring 401 by screws. At this time, the fixing ring 5 presses the blade 310 downward, so that the fixing posts 3091 at the bottom end of the fixing ring 5 are inserted into the corresponding fixing holes 303, which facilitates the fixing of the blade 310.

[0045] Further, please refer to again Figure 2 , Figure 3 , Figure 4, the vibration isolation and buffering mechanism includes two support outer frames 101, several clamping brackets 102, buffer rubbers 103, clamping grooves 104, notches 105 and limiting grooves 106. The two support outer frames 101 are fixedly installed on the outer wall of the motor 1 housing. Several clamping brackets 102 are integrally formed on the outer wall of the support outer frame 101. The clamping brackets 102 are U-shaped. The clamping grooves 104 are opened on both sides of the buffer rubber 103. The buffer rubber 103 is installed on the clamping brackets 102 through the clamping grooves 104 thereon. The notches 105 are opened at the upper and lower ends on both sides of the buffer rubber 103. The limiting grooves 106 are opened at the upper and lower ends of the buffer rubber 103. A plurality of first fixing frames 201 are fixedly installed on the inner wall of the lower housing 2. A first limiting plate 202 is fixedly installed on the inner wall of the first fixing frame 201. The first fixing frame 201 corresponds to the position of the buffer rubber 103 on the outer wall of the motor 1 housing. The first limiting plate 202 is engaged with the limiting groove 106 at the bottom of the buffer rubber 103. A plurality of second fixing frames 205 are fixedly installed on the inner wall of the upper housing 204. A second limiting plate 206 is fixedly installed on the inner wall of the second fixing frame 205. The second fixing frame 205 corresponds to the position of the buffer rubber 103 on the outer wall of the motor 1 housing. The second limiting plate 206 is engaged with the limiting groove 106 at the top of the buffer rubber 103. A plurality of clamping frames 203 are fixedly installed on the outer wall of the lower housing 2. A plurality of clamping plates 207 are fixedly installed on the outer wall of the upper housing 204. The clamping plates 207 are engaged with the corresponding clamping frames 203. The motor 1 is arranged between the lower housing 2 and the upper housing 204, and one end of the mounting shaft 107 extends to the outside of the top of the upper housing 204; by setting the vibration isolation and buffering mechanism, wherein the buffer rubber 103 is clamped on the clamping bracket 102 through the clamping groove 104, the contact area at the connection between the buffer rubber 103 and the clamping bracket 102 is increased. Compared with the traditional spherical vibration buffering structure, the buffer rubber 103 can be installed on the clamping bracket 102 more stably. By setting the notches 105 at two weak points at both ends of the outer wall of the buffer rubber 103, two effective buffer and shock damping points are respectively formed at both ends of the buffer rubber 103, the buffering performance of the buffer rubber 103 is increased, and the buffer and vibration isolation effect is enhanced. By setting the first limiting plate 202 and the second limiting plate 206 in the lower housing 2 and the upper housing 204, when the buffer rubber 103 is installed, the limiting grooves 106 at both ends of the buffer rubber 103 can be respectively clamped on the first limiting plate 202 and the second limiting plate 206, so that the buffer rubber 103 is not easily deflected in angle during installation and use, and the buffer and shock damping effect of the buffer rubber 103 is further increased.

[0046] Such as Figure 11As shown in the figure, several mounting frames 6 are fixedly installed at the bottom end of the inner wall of the mounting ring 401. The mounting frames 6 are located inside the inner ring of the corresponding conveyor belt 406. A moving block 602 is slidably installed on the inner wall of the mounting frame 6. One end of the moving block 602 is fixedly installed with a rotating frame 603. A roller 604 is rotatably installed on the inner wall of the rotating frame 603. The roller 604 is located on the surface of the inner ring of the corresponding conveyor belt 406. The other end of the moving block 602 is fixedly installed with a second spring 601. The other end of the second spring 601 is fixedly installed on one side of the inner wall of the corresponding mounting frame 6. A communication hole 503 is opened at the top of the fixed ring 5. The top end of one of the rotating columns 404 extends to the top of the mounting ring 401, and a knob 408 is fixedly installed at the end of the rotating column 404 extending to the top of the mounting ring 401. The knob 408 is located inside the communication hole 503. By setting the mounting frame 6, the second spring 601 in the mounting frame 6 supports the moving block 602 to move towards the surface of the inner ring of the conveyor belt 406, so that the roller 604 supports on the surface of the inner ring of the corresponding conveyor belt 406, making the contact between the conveyor belt 406 and the outer wall of the corresponding driving pulley 405 closer, reducing the looseness of the conveyor belt 406, and enabling the conveyor belt 406 to transmit better.

[0047] The working process and principle of the present invention: When fixing the blade 310, insert the fixed ring 5 on the top of the mounting ring 401, and align the fixed cylinder 502 on the fixed ring 5 with the fixed column 3091 at the top of the blade 310. Insert the fixed column 3091 into the corresponding fixed cylinder 502 to fix the top of the blade 310. At this time, the first threaded hole 402 on the mounting ring 401 and the second threaded hole 501 on the fixed ring 5 are aligned, and the fixed ring 5 is fixed on the top of the mounting ring 401 by screws. When the blade 310 needs to be cleaned, remove the fixed ring 5. The first spring 306 rebounds to support the rotating member 307 to move upward, thereby driving the blade 310 to move upward. The fixed column 3091 at the bottom of the blade 310 disengages from the fixing hole 303, and the fixed clamping plate 3081 at the bottom of the blade 310 disengages from the fixing groove 302, canceling the fixation of the blade 310. Twist the knob 408 by hand to drive the blade 310 to rotate and adjust the angle, so that the side wall of the blade 310 rotates towards the tail or the inside, facilitating the cleaning of the side wall of the blade 310.
