Description

Technical Field

[0001] This invention relates to the field of brushless motors, and more particularly to an integrated AC spin brushless motor. Background Technology

[0002] In today's automotive industry, with the rapid development of electric and hybrid vehicles, innovation in motor technology has become a key factor driving industry progress. Traditional brushed motors have revealed numerous problems in automotive applications, making it difficult to meet the stringent requirements of modern automobiles for high performance, high reliability, and energy efficiency. The advent of brushless motors has brought hope for solving these problems. Brushless motors replace the mechanical commutator and brushes of traditional brushed motors with an electronic commutator. Their working principle is that when the windings on the stator are energized, a rotating magnetic field is generated. The rotor, using permanent magnets, rotates under the drive of this magnetic field. A position sensor monitors the rotor position in real time and transmits the signal to the electronic commutator, which then switches the current in each phase winding accordingly, thus ensuring the continuous and stable operation of the motor. Compared to brushed motors, brushless motors have significant advantages. Existing brushless motors still have certain limitations in automotive applications. Their installation compatibility is poor; due to the different locations of mounting holes on different vehicles, existing motors require different mounting brackets for different hole positions, resulting in poor compatibility. Furthermore, when minor problems occur during operation, the existing motors require complete disassembly for inspection, necessitating repeated disassembly and reassembly, which is extremely inconvenient and wastes unnecessary time. Therefore, we propose an integrated AC spin brushless motor. Summary of the Invention

The right ends of the two crossbars pass through the two support seats respectively and are slidably connected to the two support seats respectively. The upper surface of the mounting base is fixedly connected to a locking seat on the right side of each of the two support bases, and two locking heads are fixedly connected to the right side of each support base. A fixing baffle is fixedly connected to the outer wall of the crossbar and to the left side of the support base. A spring is fixedly connected to the fixing baffle and the opposite side of the support base, located on the outer side of the crossbar.

[0005] Furthermore, a first connecting ring is fixedly connected to the outer wall of the motor body and located on the right side of the housing, and a second connecting ring is fixedly connected to the right side of the housing and located on the outer side of the motor body. The first connecting ring and the second connecting ring are connected by bolts.

[0007] 4. An integrated AC spin brushless motor according to claim 3, characterized in that: the left end of the adjusting screw passes through the fixing plate located on the left side of the upper surface of the mounting base, and is fixedly connected to a knob.

[0008] 5. An integrated AC spin brushless motor according to claim 3, characterized in that: symmetrical through-type longitudinal grooves are provided on both sides of the hollow strip; a bidirectional screw is rotatably connected to the interior of the hollow strip via a rotating shaft; two threaded blocks are threadedly connected to the outer side wall of the bidirectional screw; a rotating joint is fixedly connected to the inner side of each of the two longitudinal grooves on opposite sides of the threaded block; a traction rod is rotatably connected to the upper surface of the rotating joint via a rotating shaft; a rotating joint is rotatably connected to the end of the traction rod away from the rotating joint; and an installation strip is fixedly connected to the ends of the two rotating joints on the same side away from the hollow strip.

[0009] 6. An integrated AC spin brushless motor according to claim 5, characterized in that: a storage groove is provided on both the front and rear surfaces of the mounting strip, an extension rod is slidably connected inside the storage groove, and a mounting sleeve is fixedly connected to the opposite ends of the two opposite extension rods.

[0010] 7. An integrated AC spin brushless motor according to claim 5, characterized in that: both ends of the bidirectional screw pass through the front and rear of the hollow strip respectively and are fixedly connected to a knob.

[0011] 8. An integrated AC spin brushless motor according to claim 1, characterized in that: two through-type insertion vertical slots are provided on the left side of the locking seat.

[0012] 9. An integrated AC spin brushless motor according to claim 8, characterized in that: the engaging head is inserted into the interior of the engaging vertical slot, a rotating stop is provided on the right side of the engaging head, a sliding rod is fixedly connected inside the rotating stop, a connecting head is slidably connected to the outer wall of the sliding rod, the left side of the connecting head is rotatably connected to the right side of the engaging head through a rotating shaft, and a spring is sleeved on the opposite side of the connecting head and the rotating stop, located on the outer wall of the sliding rod.

[0013] Beneficial effects: By rotating knob one, the adjusting screw drives threaded block one and the hollow strip to move horizontally within the mounting groove, achieving overall lateral position adjustment; rotating knob two causes the two threaded blocks two to move in opposite directions via the bidirectional screw, which in turn drives the mounting strip to move horizontally through rotating joint one, the traction rod, and rotating joint two, adjusting the opening and closing distance between the mounting strips. This allows the mounting sleeve to precisely match the left and right spacing of the pre-drilled mounting holes on the vehicle. By pulling the extension rod on the mounting strip out of the storage slot to a suitable length, the spacing between the two opposing mounting sleeves can be adjusted to align with the positions of the two opposing pre-drilled holes, thus resolving the compatibility issue caused by varying front and rear spacing of the mounting holes. Through multi-dimensional adjustments, the adaptability of motor installation is greatly improved, allowing it to accommodate different automotive pre-drilled hole positions without requiring replacement of the mounting base. The motor body is fixed to the housing with bolts via connecting ring one and connecting ring two. During maintenance, only the bolts need to be unscrewed to remove the motor body from the housing. There is no need to disassemble the connection between the motor and the mounting base, which reduces a lot of disassembly and installation steps. Move the support to the left to disengage the locking head from the vertical slot. The crossbar can then rotate around the axis, tilting the housing and motor body to an inclined position. The right side of the motor body tilts upward, facilitating its removal from the inside of the housing. This avoids the hassle of having to disassemble the motor body along with the mounting base due to its proximity to the driven part, saving significant maintenance time and improving repair efficiency. After the locking head on the support is inserted into the vertical slot of the locking seat, the rotating block rotates to a position perpendicular to the vertical slot. The tension of the spring makes the rotating block fit tightly against the right side of the locking seat, preventing the locking head from coming out due to vehicle movement or motor vibration. Even if the rotating block rotates to a vertical position due to vibration, its left side will be misaligned with the right side of the locking head under the pull of the second spring, and will not completely overlap with the vertical slot of the insertion. The misalignment of the rotating block, which rotates to a horizontal position, and the second spring form a double anti-disengagement mechanism to ensure that the motor is installed firmly and to avoid loosening during operation that would affect its use.

[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example like Figure 1, Figure 2 , Figure 6 and Figure 8 As shown, an integrated AC spin brushless motor is provided, including a motor body 1, and a housing 2 is fitted onto the outer side wall of the motor body 1. Two support seats 3 are fixedly connected to the lower surface of the housing 2. A mounting seat 4 is provided at the bottom of the two support seats 3. Rotating seats 5 are fixedly connected symmetrically to the left side of the upper surface of the mounting seat 4. The inner front surface and inner rear surface of the rotating seat 5 are rotatably connected to the shaft 6 through the rotating shaft. A crossbar 7 is fixedly connected to the opposite ends of the two adjacent shafts 6. The right ends of the two crossbars 7 pass through the two support seats 3 respectively and are slidably connected to the two support seats 3 respectively. The upper surface of the mounting base 4 is fixedly connected to the right side of both support bases 3 with locking seats 8, and the right side of the support base 3 is fixedly connected to two locking heads 9. A fixed baffle 10 is fixedly connected to the outer wall of the crossbar 7 and to the left side of the support base 3. A spring 11 is fixedly connected to the opposite side of the fixed baffle 10 and the support base 3 and to the outer side of the crossbar 7. A connecting ring 12 is fixedly connected to the outer wall of the motor body 1 and to the right side of the housing 2. A connecting ring 23 is fixedly connected to the right side of the housing 2 and to the outer side of the motor body 1. The connecting ring 12 and the connecting ring 23 are connected by bolts. The left end of the adjusting screw 17 passes through the fixing plate 16 located on the left side of the upper surface of the mounting base 4, and is fixedly connected to the knob 20; Two through-type vertical slots 32 are provided on the left side of the card holder 8; The motor body 1 is snapped into the housing 2 and fixed with bolts by connecting ring 12 and connecting ring 2, so as to achieve a stable connection between the motor body 1 and the housing 2, which facilitates subsequent disassembly and maintenance of the motor interior. The housing 2 with support base 3 is made to have the crossbar 7 pass through the support base 3, so that the support base 3 can drive the housing 2 and the motor body 1 to slide along the outside of the crossbar 7 on the upper surface of the mounting base 4. The spring 11 on the fixed baffle 10 presses the support base 3 to the right, so that the two locking heads 9 on the support base 3 are inserted into the insertion vertical groove 32 of the locking seat 8, so that the motor body 1 can be placed horizontally on the mounting base 4. At this time, it is convenient to connect the output shaft part of the motor body 1 with the driven part on the vehicle, so that the motor body 1 can start and drive the part. When the motor body 1 needs to be repaired, first separate the output shaft of the motor body 1 from the mounting part, and then move the support seat 3 to the left. At this time, the spring 11 is compressed and contracted, and the locking head 9 can be disengaged from the insertion vertical slot 32. At this time, the left end of the crossbar 7 can be used to rotate around the shaft 6 along the inner side of the rotating seat 5, thereby rotating the horizontally placed housing 2 and motor body 1 to an inclined state, and making the right side of the motor body 1 tilt upward. At this time, the bolts connecting the connecting ring 12 and the connecting ring 23 are removed with a screwdriver, so that the motor body 1 is separated from the housing 2. At this time, the motor body 1 can be pulled out from the inside of the housing 2 at an inclined upward. This avoids the problem in the prior art that after the motor body 1 is installed, it is not easy to remove because the distance between the motor body 1 and the part to be driven is too close, and it is necessary to remove the mounting seat 4 together, which requires back and forth installation, which is inconvenient and wastes time. After the maintenance is completed, the motor body 1 is put back into the housing 2 and threaded. Then, the crossbar 7 is rotated to make the motor body 1 horizontal again, and the output shaft of the motor body 1 is reconnected to the drive part.

[0018] like Figure 7 , Figure 8 and Figure 9 As shown, the engaging head 9 is inserted into the insertion vertical groove 32. A rotating stop 33 is provided on the right side of the engaging head 9. A sliding rod 34 is fixedly connected inside the rotating stop 33. A connector 35 is slidably connected to the outer wall of the sliding rod 34. The left side of the connector 35 is rotatably connected to the right side of the engaging head 9 through a rotating shaft. A spring 36 is sleeved on the opposite side of the connector 35 and the rotating stop 33 and on the outer wall of the sliding rod 34. After the engaging head 9 is inserted into the vertical slot 32, the rotating stop 33 is rotated to be perpendicular to the vertical slot 32 to prevent the vehicle body from moving or the engaging head 9 from disengaging from the vertical slot 32 due to vibration caused by the motor body 1, which would lead to instability of the motor body 1. Furthermore, the rotating stop 33 passes through the vertical slot 32, and its left side is pulled by spring 11, allowing it to tightly fit against the right side of the engaging seat 8. Simultaneously, the sliding rod 34, connector 35, and spring 36 ensure that even if the engaging head 9 and the engaging seat 8 are engaged... After the seat 8 is inserted, vibration causes the rotating stop 33 to rotate into a vertical position. Under the pull of the second spring 36, the left side of the vertical rotating stop 33 will not completely overlap with the right side of the engaging head 9, but will be in a misaligned state. This avoids the problem of the engaging head 9 easily coming off due to vibration after being completely overlapped with the insertion vertical groove 32. By rotating the rotating stop 33 to a horizontal state and by pulling the rotating stop 33 with the second spring 36 to make the rotating stop 33 misaligned, the problem of the engaging head 9 easily coming off due to vibration after being engaged is prevented through two steps of anti-disengagement measures.

[0019] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the front surface of the mounting base 4 has a through mounting groove 14, and the upper surface of the inner surface of the mounting groove 14 has a through horizontal groove 15. The upper surface of the mounting base 4 is fixedly connected to both sides of the mounting groove 14 with fixing plates 16. The two fixing plates 16 are rotatably connected to the adjusting screw 17 through a rotating shaft. The outer wall of the adjusting screw 17 and the inner side of the mounting groove 14 are threadedly connected to a threaded block 18. The bottom of the threaded block 18 is fixedly connected to a hollow strip 19 inside the mounting groove 14. The hollow strip 19 has symmetrical through-type longitudinal grooves 21 on both sides. The hollow strip 19 is rotatably connected to a bidirectional screw 22 via a rotating shaft. The outer wall of the bidirectional screw 22 is threaded with two threaded blocks 23. Rotary joints 24 are fixedly connected to the inner sides of the two longitudinal grooves 21 on both sides of the threaded blocks 23. The upper surface of the rotary joints 24 is rotatably connected to a traction rod 25 via a rotating shaft. The end of the traction rod 25 away from the rotary joints 24 is rotatably connected to a rotary joint 26 via a rotating shaft. The ends of the two rotary joints 26 on the same side away from the hollow strip 19 are fixedly connected to an installation strip 27. The front and rear surfaces of the mounting strip 27 are provided with storage grooves 28. An extension rod 29 is slidably connected inside the storage groove 28. The opposite ends of the two extension rods 29 are fixedly connected with mounting sleeves 30. The two ends of the bidirectional screw 22 pass through the front and rear of the hollow strip 19 respectively and are fixedly connected to the knob 31; Rotate knob 2 31 to drive the bidirectional screw 22 to rotate, causing the two threaded blocks 23 to move in opposite directions. This, through rotating joint 1 24, traction rod 25, and rotating joint 26, drives the mounting strip 27 to move horizontally. Adjust the spacing between the two mounting sleeves 30 according to the left and right spacing of the reserved mounting holes on the car, so that the left and right distance of the mounting sleeves 30 can be adjusted to be consistent with the left and right spacing of the reserved mounting holes. Pull the extension rod 29 on the mounting strip 27 out of the storage slot 28 to a suitable length so that the interval between the two front and rear opposite mounting sleeves 30 is consistent with the position of the two front and rear opposite reserved holes; Rotate knob 20 to drive adjusting screw 17 to rotate, causing threaded block 18 to drive hollow bar 19 to move horizontally within mounting groove 14, thereby adjusting the left and right spacing and front and back spacing to the reserved hole. Then, by moving mounting sleeve 30 left or right for fine adjustment, multiple mounting sleeves 30 are connected to multiple reserved holes. Then, bolts are used to thread the mounting sleeves 30 to the reserved holes to install mounting base 4, so that motor body 1 can be installed on the vehicle.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
