Description

Technical Field

[0001] The invention relates to the field of double-stator motors, and in particular to an output line clamping structure and a double-stator motor. Background Art

[0002] The motor is mainly composed of stator, rotor, shaft and housing. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate current. The dual-stator motor is a motor with two stators. Figure 1 As shown, when the stator includes a three-phase winding, the two stators have twelve output lines, namely: a first output line 01, a second output line 02, a third output line 03, a fourth output line 04, a fifth output line 05, a sixth output line 06, a seventh output line 07, an eighth output line 08, a ninth output line 09, a tenth output line 010, an eleventh output line 011 and a twelfth output line 012, wherein the first output line 01, the second output line 02, the third output line 03, the fourth output line 04, the fifth output line 05 and the sixth output line 06 correspond to the winding of one stator, and the seventh output line 07, the eighth output line 08, the ninth output line 09, the tenth output line 010, the eleventh output line 011 and the twelfth output line 012 correspond to the winding of the other stator. When the two stators need to be connected in series or in parallel, each winding needs to be wound and the ends of each output line need to be bent into a junction box for centralized processing and connection.

[0003] However, since there are many output wires, each output wire needs to be bent, and the bending shapes of each output wire are different, the process is complicated. In addition, in order to adapt to the terminal box with a short axial dimension, the output wire even needs to be bent twice, resulting in low processing efficiency of the winding. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a clamping structure for output wires with compact structure and efficient winding process.

[0005] An output line clamping structure is installed on a motor housing and is used to clamp and fix the first to twelfth output lines led out from the motor housing. The clamping structure includes:

[0006] A first wiring block, wherein the first wiring block is provided with three first fixing parts for fixing the first, third and fifth output lines respectively;

[0007] A second wiring block, wherein the second wiring block is provided with three second fixing parts for fixing the second, fourth and sixth output lines respectively;

[0008] A third wiring block, located at a side of the second wiring block away from the first wiring block, the third wiring block is provided with three third fixing parts, respectively fixing the eighth, tenth and twelfth output lines;

[0009] The fourth wiring block is located at a side of the third wiring block away from the second wiring block. The fourth wiring block is provided with three fourth fixing parts for fixing the seventh, ninth and eleventh output lines respectively.

[0010] Optionally, the first fixing portion is located on an upper portion of the first wiring block, so that the first, third and fifth output lines respectively pass through a side of the first wiring block away from the second wiring block and are fixed to an upper portion of the first wiring block.

[0011] Optionally, three first via holes are formed at the lower portion of the first wiring block, so that the second, fourth and sixth output lines pass through the first via holes in sequence and are bent and fixed on the second fixing portion.

[0012] Optionally, the third fixing portion is located on the upper portion of the third wiring block, so that the eighth, tenth and twelfth output lines all pass between the third wiring block and the fourth wiring block and are fixed to the upper portion of the third wiring block.

[0013] Optionally, a fourth through hole is provided at the bottom of the fourth wiring block, so that the seventh, ninth and eleventh output lines pass through the fourth through hole and are bent and fixed to the fourth fixing portion, which is located on a side of the fourth wiring block away from the third wiring block.

[0014] Optionally, the first wiring block, the second wiring block, the third wiring block and the fourth wiring block are all arc-shaped.

[0015] Optionally, it also includes:

[0016] Three external phase lines are respectively connected to the seventh, ninth and eleventh output lines.

[0017] Optionally, the first to twelfth output lines are all flat lines.

[0018] Optionally, it also includes:

[0019] a first connecting bar fixed between the first wiring block and the third wiring block, wherein the first output line and the eighth output line, the third output line and the tenth output line, and the fifth output line and the twelfth output line are all connected via the first connecting bar;

[0020] A second connecting bar is fixed on the second wiring block and connects the second, fourth and sixth output lines.

[0021] The present invention also provides a dual-stator motor, comprising the output line clamping structure of the above embodiment.

[0022] Compared with the prior art, this technical solution has the following advantages:

[0023] The output wires of the dual-stator motor are fixed by the first terminal block, the second terminal block, the third terminal block and the fourth terminal block, where only six output wires need to be bent, which reduces the process difficulty and improves the efficiency of the card installation. The card installation structure uses the bent and dislocated output wires to reduce the overall volume, thereby further reducing the volume of the adapted terminal box, reducing the axial volume of the motor, and improving the applicable scenarios of the motor. In addition, the dual-stator motor adopts short-pitch windings, so that the output wires are more compactly distributed on the circumference.

[0036] like Figures 2 to 6As shown, the output line clamping structure 100 is installed on the motor housing 200, and is used to clamp and fix the first output line 01, the second output line 02, the third output line 03, the fourth output line 04, the fifth output line 05, the sixth output line 06, the seventh output line 07, the eighth output line 08, the ninth output line 09, the tenth output line 010, the eleventh output line 011 and the twelfth output line 012 led out from the motor housing 200, and the clamping structure 100 includes:

[0037] A first wiring block 110, fixed on the motor housing 200, and the first wiring block 110 is provided with three first fixing parts 111, which respectively fix the first output line 01, the third output line 03 and the fifth output line 05;

[0038] A second wiring block 120, fixed on the motor housing 200, and the second wiring block 120 is provided with three second fixing parts 121, which respectively fix the second output line 02, the fourth output line 04 and the sixth output line 06;

[0040] a fourth wiring block 140, fixed on the motor housing 200 and located on a side of the third wiring block 130 away from the second wiring block 120, the fourth wiring block 140 is provided with three fourth fixing parts, respectively fixing the seventh output line 07, the ninth output line 09 and the eleventh output line 011;

[0041] 3. A first connecting bar 150, fixed between the first wiring block 110 and the third wiring block 130, the first output line 01 and the eighth output line 08, the third output line 03 and the tenth output line 010, and the fifth output line 05 and the twelfth output line 012 are all connected via the first connecting bar 150;

[0042] A second connecting bar 160 is fixed on the second wiring block 120 , and the second output line 02 , the fourth output line 04 and the sixth output line 06 are connected via the second connecting bar 160 .

[0043] like Figures 2 to 4As shown, the first fixing portion 111 is located on the side of the first wiring block 110 away from the motor housing 200, that is, the first fixing portion 111 is located on the upper part of the first wiring block 110, so that the first output line 01, the third output line 03 and the fifth output line 05 pass through the side of the first wiring block 110 away from the second wiring block 120 respectively, and are fixed to the upper part of the first wiring block 110.

[0044] Three first through holes 112 are provided on a side of the first wiring block 110 away from the first fixing portion 111, that is, three first through holes 112 are provided at the lower portion of the first wiring block 110, so that the second output line 02, the fourth output line 04 and the sixth output line 06 pass through the first through holes 112 in sequence and are bent and fixed on the second fixing portion 121, and the second fixing portion 121 is located at the upper portion of the second wiring block 120.

[0045] Specifically, the first output line 01, the third output line 03 and the fifth output line 05 are in a vertical state, while the second output line 02, the fourth output line 04 and the sixth output line 06 are in a bent state, that is, only the second output line 02, the fourth output line 04 and the sixth output line 06 need to be bent, which effectively improves the clamping efficiency of the output lines.

[0046] In addition, the bending angles of the second output line 02, the fourth output line 04 and the sixth output line 06 are determined by the distance between the first wiring block 110 and the second wiring block 120, and the height of the second wiring block 120. In one example, the bending angles of the second output line 02, the fourth output line 04 and the sixth output line 06 are 15 to 60 degrees, preferably 45 degrees.

[0047] like Figures 2 to 5 As shown, the third fixing portion 131 is located on the upper portion of the third wiring block 130 so that the eighth output line 08 , the tenth output line 010 and the twelfth output line 012 all pass between the third wiring block 130 and the fourth wiring block 140 and are fixed to the upper portion of the third wiring block 130 .

[0048] A fourth through hole 142 is provided at the lower portion of the fourth wiring block 140, so that the seventh output line 07, the ninth output line 09 and the eleventh output line 011 pass through the fourth through hole 142 in sequence and are bent and fixed to the fourth fixing portion, which is located on the side of the fourth wiring block 140 away from the third wiring block 130.

[0049] Specifically, the eighth output line 08, the tenth output line 010 and the twelfth output line 012 are in a vertical state, while the seventh output line 07, the ninth output line 09 and the eleventh output line 011 are in a bent state, that is, only the seventh output line 07, the ninth output line 09 and the eleventh output line 011 need to be bent, which effectively improves the clamping efficiency of the output lines.

[0050] In summary, among the twelve output wires of the dual-stator motor, the lengths of all the output wires can be consistent and are led out radially along the winding. During installation, only six output wires need to be bent, which reduces the process difficulty and improves the installation efficiency.

[0051] like Figure 3 and Figure 6 As shown, a terminal block mounting portion 210 is provided on one radial side of the motor housing 200, and the first terminal block 110, the second terminal block 120, the third terminal block 130 and the fourth terminal block 140 are mounted on the terminal block mounting portion 210. The first output line 01, the second output line 02, the third output line 03, the fourth output line 04, the fifth output line 05, the sixth output line 06, the seventh output line 07, the eighth output line 08, the ninth output line 09, the tenth output line 010, the eleventh output line 011 and the twelfth output line 012 all pass through the terminal block mounting portion 210.

[0052] Continue to refer Figure 3 , the wiring block mounting portion 210 is convex, and the first wiring block 110, the second wiring block 120, the third wiring block 130 and the fourth wiring block 140 are all arc-shaped, so as to be mounted on the convex wiring block mounting portion 210. Of course, the wiring block mounting portion 210 may also be concave, so that the first wiring block 110, the second wiring block 120, the third wiring block 130 and the fourth wiring block 140 can be mounted on the wiring block mounting portion 210 in a coordinated manner.

[0053] The height of the second wiring block 120 is lower than that of the first wiring block 110 and the third wiring block 130, so that the first connecting bar 150 is fixed between the first wiring block 110 and the third wiring block 130, and the second output line 02, the fourth output line 04 and the sixth output line 06 can be bent.

[0054] like Figures 1 to 3As shown, the first fixing portion 111, the second fixing portion 121, the third fixing portion 131 and the fourth fixing portion are all threaded holes and are fixed by a fastener 170. For example, the fastener 170 and the first fixing portion 111 are screwed together to fix the first output line 01 on the first wiring block 110. The fastener 170 may be a screw or a bolt.

[0055] like Figure 2 and Figure 3 As shown, the output line clamping structure 100 further includes three first wiring noses 181 , three second wiring noses 182 , three third wiring noses 183 and three fourth wiring noses 184 .

[0056] The first output line 01, the third output line 03, and the fifth output line 05 are respectively connected to the first wiring nose 181, and are fixed to the first wiring block 110 by means of fasteners 170. The first wiring nose 181 is in a right angle shape, wherein the first output line 01, the third output line 03, and the fifth output line 05 are all in a vertical state, and thus can be fixed to the first wiring block 110 by means of the first wiring nose 181 in a right angle shape.

[0057] The second output line 02, the fourth output line 04 and the sixth output line 06 are respectively connected to the second wiring nose 182, and are fixed to the second wiring block 120 by fasteners 170. The second wiring nose 182 is beveled, wherein the second output line 02, the fourth output line 04 and the sixth output line 06 are all in a bent state, so the second wiring nose 182 in beveled shape can be used to fix them to the second wiring block 120, and the bevel angle of the second wiring nose 182 is affected by the bending angle of the second output line 02, for example, if the bending angle of the second output line 02 is 45°, then the bevel angle of the second wiring nose 182 is 135°.

[0058] The eighth output line 08, the tenth output line 010 and the twelfth output line 012 are connected to the third wiring nose 183 respectively, and are fixed to the third wiring block 130 by fasteners 170. The third wiring nose 183 is in a right angle shape, wherein the eighth output line 08, the tenth output line 010 and the twelfth output line 012 are all in a vertical state, so they can be fixed to the third wiring block 130 by using the right angle third wiring nose 183. Figure 3 and Figure 6 The third wiring nose 183 is arranged opposite to the first wiring nose 181.

[0059] The seventh output line 07, the ninth output line 09 and the eleventh output line 011 are respectively connected to the fourth wiring nose 184 and fixed to the fourth wiring block 140 by fasteners 170. The fourth wiring nose 184 is in an oblique angle, wherein the seventh output line 07, the ninth output line 09 and the eleventh output line 011 are all in a bent state, so the fourth wiring nose 184 in an oblique angle can be fixed to the fourth wiring block 140. The oblique angle of the fourth wiring nose 184 is affected by the bending angle of the seventh output line 07, and its inclination angle can be 60 to 165°.

[0060] In summary, the first wiring nose 181, the second wiring nose 182, the third wiring nose 183 and the fourth wiring nose 184 are all made of copper material, and play the role of output line conduction. The first wiring nose 181 and the third wiring nose 183 are both right-angled, and the second wiring nose 182 and the fourth wiring nose 184 are oblique-angled. Among them, the surface of the second wiring nose 182 in contact with the second wiring block 120 is a horizontal surface, and the surface of the fourth wiring nose 184 in contact with the fourth wiring block 140 is a vertical surface.

[0061] like Figure 1 and Figure 4 As shown, the front and rear windings of this embodiment are connected in series, the motor windings are star-connected, and the winding pitch is 1, so the position of the motor output line is more compact in the circumferential direction of the motor.

[0062] The first connecting bar 150 and the second connecting bar 160 are conductors, which play the role of connecting the front and rear windings and constructing a star point.

[0063] Specifically, the first connecting bar 150 is Z-shaped, and the two ends are respectively fixed to the first fixing portion 111 and the third fixing portion 131, and fixed by the fastener 170. It should be noted that the first wiring nose 181 can be embedded in the first wiring block 110, and the third wiring nose 183 can be embedded in the third wiring block 130, and then the two ends of the first connecting bar 150 are respectively corresponding to the first wiring nose 181 and the third wiring nose 183, and finally fixed by the fastener 170.

[0064] The second connecting bar 160 is in a straight line shape. The second wiring nose 182 can be placed on the second wiring block 120 first, and then the second connecting bar 160 can be placed on the second wiring nose 182 and fixed by the fastener 170 .

[0065] like Figure 3 and Figure 4As shown, the first wiring block 110, the second wiring block 120, the third wiring block 130 and the fourth wiring block 140 are arranged along the axis direction of the motor, wherein there may be a gap between the first wiring block 110 and the second wiring block 120, the second wiring block 120 and the third wiring block 130 may be integrally formed, and there is a gap between the third wiring block 130 and the fourth wiring block 140 to allow the eighth output line 08, the tenth output line 010 and the twelfth output line 012 to pass through.

[0066] refer to Figure 3 The fourth wiring block 140 is provided with an abutting portion 143 on one side facing the third wiring block 130, abutting against the third wiring block 130, so that there is a gap between the third wiring block 130 and the fourth wiring block 140. There are multiple abutting portions 143, and they are staggered with the fourth vias 142. For example, the abutting portions 143 and the fourth vias 142 are arranged in sequence.

[0067] The first terminal block 110, the second terminal block 120, the third terminal block 130 and the fourth terminal block 140 can all be fixed to the motor housing 200 by fasteners 170. For example, the first terminal block 110 and the third terminal block 130 are both fixed to the motor housing 200 by fasteners 700, the second terminal block 120 and the third terminal block 130 are an integral structure, and the fourth terminal block 140 is fixed to the third terminal block 130 by the fasteners 700.

[0068] like Figures 1 to 5 As shown, the output line clamping structure 100 further includes three external phase lines 190 , and the seventh output line 07 , the ninth output line 09 and the eleventh output line 011 are connected to the external phase lines 190 respectively.

[0069] Specifically, the connection between the seventh output line 07, the ninth output line 09 and the eleventh output line 011 and the fourth wiring block 140 is located on the side of the fourth wiring block 140 away from the third wiring block 130, that is, the external phase line 190 is located on the side of the fourth wiring block 140 away from the third wiring block 130. During installation, the seventh output line 07, the ninth output line 09 and the eleventh output line 011 sequentially pass through the fourth through hole 142 and correspond to the fourth fixing portion through the fourth wiring nose 184, and then the external phase line 190 is placed on the fourth wiring nose 184 and fixed by the fastener 170.

[0070] refer to Figure 5, the external phase line 190 is arranged along the radial direction of the motor. It should be noted that the external phase line 190 is also connected to the fourth wiring nose 184 through a wiring nose, and the outlet direction of the external phase line 190 can be changed by changing the angle of the wiring nose. For example, if the wiring nose is a right angle, the external phase line 190 is outlet along the axis direction of the motor.

[0071] In addition, the installation position of the external phase line 190 is determined by the fixed position of the fourth wiring nose 184 and the fourth wiring block 140. That is, the installation position of the external phase line 190 is affected by the fourth fixing part, and the bending angles of the seventh output line 07, the ninth output line 09 and the eleventh output line 011 are also affected by the fourth fixing part. If the bending angle changes, it can be changed by replacing the fourth wiring nose 184 and the wiring nose connected to the external phase line 190.

[0072] Flat wire motors have the advantages of small size, less material, high efficiency, low temperature rise, and low noise. Therefore, the first output wire 01, the second output wire 02, the third output wire 03, the fourth output wire 04, the fifth output wire 05, the sixth output wire 06, the seventh output wire 07, the eighth output wire 08, the ninth output wire 09, the tenth output wire 010, the eleventh output wire 011, and the twelfth output wire 012 are all flat wires, which are enameled wires with a rectangular cross section.

[0073] In summary, the first terminal block 110, the second terminal block 120, the third terminal block 130 and the fourth terminal block 140 are used to fix the output wires of the dual-stator motor, wherein only six output wires need to be bent, which reduces the process difficulty and improves the clamping efficiency.

[0074] The present invention also provides a dual-stator motor, including the output wire clamping structure 100 of the above embodiment. Since the dual-stator motor adopts the output wire clamping structure 100 of the above embodiment, the beneficial effects of the dual-stator motor brought by the output wire clamping structure 100 refer to the above embodiment.

The clamping structure 100 is installed in the radial direction of the motor housing 200 to clamp the output wires led out from the motor housing 200.

[0076] The dual-stator motor also includes a junction box, which is fixed to the outside of the motor housing 200, and the first junction block 110, the second junction block 120, the third junction block 130, the fourth junction block 140 and the output line are located inside the junction box, and the external phase line 190 passes through the junction box.

[0077] The output line clamping structure 100 is compact, and the output line is staggered to reduce the volume, which can further reduce the volume of the junction box and reduce the axial volume of the motor.
