[0042] The utility model provides a kind of middle shaft axial motor integrated drive system 100, specifically, please refer to Figure 1 And Figure 2 In the embodiment, middle shaft axial motor integrated drive system 100 includes motor main body 1 and reduction gear 2, motor main body 1 includes stator assembly and the lead-in wire 12 connected with the stator assembly at one end;Reduction gear 2 is arranged at the axial side of the motor main body 1;Wherein, the lead-in wire 12 is extended along the axial direction of the motor main body 1 after leading out from the stator assembly, to be inserted from one end of the reduction gear 2 to the other end of the reduction gear 2, and then be arranged out from the circumferential side of the reduction gear 2.

[0043] In the embodiment, motor main body 1 and reduction gear 2 are arranged side by side along the axial direction, and the structure is compact and occupies less space in the axial direction. Moreover, the lead-in wire 12 of the motor main body 1 is extended along the axial direction of the motor main body 1 after leading out from the stator assembly, to be inserted from one end of the reduction gear 2 to the other end of the reduction gear 2, and then be arranged out from the circumferential side of the reduction gear 2. Thus, the lead-in wire 12 is directly arranged along the axial direction after leading out from the stator assembly, without occupying more radial space of the motor main body 1, so that the size of the motor main body 1 in the radial direction can be smaller. Moreover, the lead-in wire 12 is arranged along the radial direction after being inserted into the reduction gear 2, to be arranged along the radial surface of the reduction gear 2, so that the lead-in wire 12 does not occupy more space in the axial direction. Finally, the lead-in wire 12 is led out from the circumferential side of the reduction gear 2, preferably from the side facing the control device 300, so that the lead-in wire 12 can be better connected to the control device 300, and the connection is more convenient. Moreover, the volume of the entire middle shaft axial motor integrated drive system 100 is smaller, and the occupied space is smaller, which is more conducive to the optimization of the structure of the frame structure assembly 1000.

[0044] Among them, as Figure 1 AndFigure 3 As shown in the figure, the motor body 1 comprises a motor shell 11 and a driving shaft, and a stator assembly is arranged in the motor shell 11. Preferably, the motor shell 11 is arranged in a substantially disc shape, the driving shaft is located at the middle of the motor shell 11 and can extend from one axial end of the motor shell 11, and the driving shaft is at least partially inserted into the speed reducer 2 and is drivingly connected with the speed reduction gear 22 of the speed reducer 2. The rotation of the driving shaft drives the rotation of the speed reduction gear 22 to realize the transmission of torque.

[0045] In combination Figure 1 And Figure 2 As shown in the figure, the speed reducer 2 comprises a speed reducer shell 21 and a speed reduction gear 22 arranged in the speed reducer shell 21. Preferably, the shape of the speed reducer shell 21 matches the shape of the motor shell 11, and the speed reducer shell 21 is also arranged in a disc shape, and the size of the speed reducer shell 21 is approximately the same as the size of the motor shell 11. The speed reduction gear 22 can be arranged as a primary gear, a secondary gear or a planetary gear, etc. Preferably, the speed reduction gear 22 is arranged as a primary gear, and the speed reduction gear 22 comprises a first gear 221 and a second gear 222 engaged with each other. The first gear 221 is arranged in the same shaft as the driving shaft, and the first gear 221 can be directly or indirectly connected with the driving shaft. The first gear 221 is driven to rotate by the driving shaft, and the second gear 222 is driven to rotate. The second gear 222 is arranged in a side-by-side engagement with the first gear 221 along the radial direction of the driving shaft. The second gear 222 is arranged radially offset from the center of the speed reducer shell 21 to one side, so that a space is formed on the other side of the speed reducer shell 21. The space can better accommodate the lead wire 12, so that the lead wire 12 does not occupy additional shell space in the radial and axial directions of the speed reducer shell 21, and the structure is more compact, and the volume of the speed reducer 2 is smaller.

[0046] In the outer side of the speed reducer shell 21, an output gear can also be arranged, which is coaxially connected with the second gear 222 and located on the side of the speed reducer shell 21 away from the motor body 1. The output gear is connected with a driving chain or the like to drive the rotation of the wheels of the vehicle.

[0047] Preferably, as Figure 3As shown in FIG. 1, the lead wire 12 penetrates into the first side of the speed reducer 2 in the radial direction, extends for a distance in the axial direction, and then penetrates out of the second side of the speed reducer 2 in the radial direction. The first side and the second side of the speed reducer 2 are arranged in the circumferential direction of the speed reducer 2 at intervals, so that the lead wire 12 can better penetrate out of the side opposite to the control device 300, facilitating the connection of the lead wire 12 with the control device 300. Specifically, after the lead wire 12 penetrates out of the stator assembly, the lead wire 12 penetrates into the speed reducer 2 from the first side of the speed reducer 2, extends close to the shell of the speed reducer 21 in the axial direction, and then bends in the radial direction after penetrating into the other side of the speed reducer 21 in the axial direction, so as to extend towards the second side of the speed reducer 21, thereby facilitating the extension of the lead wire 12 out of the second side of the speed reducer 21 to be connected with the control device 300. Since the lead wire 12 extends along the edge region close to the stator assembly, it does not occupy too much space in the radial direction of the motor main body, and after extending into the speed reducer 21, it extends along the edge region of the speed reducer 21, so that the speed reducer 21 does not need to increase additional space to accommodate the lead wire 12, making the lead-out of the integrated drive system 100 of the center axial motor more convenient, without increasing the overall volume, and the structure is more compact.

[0048] It can be understood that the lead wire 12 can be composed of an entire lead wire, which penetrates out of the stator assembly, passes through the speed reducer 2, and then penetrates out of the speed reducer 21. Of course, the lead wire 12 can also be composed of a plurality of lead wire segments connected in sequence, so as to better adjust the direction of the lead wire 12.

[0049] Preferably, in combination with Figure 2 and Figure 3 As shown in FIG. 1, the lead wire 12 includes a first lead wire segment 121 and a second lead wire segment 122, and an adapter connecting one end of the first lead wire segment 121 and one end of the second lead wire segment 122. The other end of the first lead wire segment 121 is connected with the stator assembly, and the other end of the second lead wire segment 122 extends out of the speed reducer 2, and the first lead wire segment 121 and the second lead wire segment 122 are arranged at an angle. The first lead wire segment 121 and the second lead wire segment 122 are accommodated in the accommodation space and arranged around the outer periphery of the speed reducer gear 22. The first lead wire segment 121 has a first segment arranged in the axial direction of the motor main body 1, and a second segment arranged laterally from the first segment. The first segment is arranged close to the edge of the motor shell 11 and the speed reducer shell 21, and the second segment extends towards the second side of the speed reducer shell 21 to be connected with the second lead wire segment 122. One end of the second lead wire segment 122 is connected with the second segment of the first lead wire segment 121, and the other end of the second lead wire segment 122 extends towards the direction of the control device 300 after extending out of the speed reducer 21.

[0050] Further, for the convenience of the connection of the first wire segment 121 and the second wire segment 122, a first terminal 1211 is arranged at the other end of the first wire segment 121, and a second terminal 1221 and a third terminal 1222 are arranged at the two ends of the second wire segment 122 respectively, the first terminal 1211 and the second terminal 1221 are connected through an adapter, and the third terminal 1222 can be extended from the speed reducer 2 to be connected with the control device 300. By connecting the first terminal 1211 and the second terminal 1221, and connecting the third terminal 1222 with the control device 300, the control device 300 is connected with the stator assembly in communication, so as to better control the motor body 1 to work.

[0051] It can be understood that the first terminal 1211 and the second terminal 1221 are electrically connected by welding or bonding. Preferably, a first mounting hole is arranged on the first terminal 1211, a second mounting hole is arranged on the second terminal 1221, and the first terminal 1211 and the second terminal 1221 are arranged correspondingly. The adapter can be a connecting bolt, which is arranged in the first mounting hole and the second mounting hole to connect and fix the first terminal 1211 and the second terminal 1221. The connecting bolt can include a screw and a nut, which are screwed together. After the screw is arranged in the first mounting hole and the second mounting hole, the nut is locked at the end of the screw, thereby connecting and fixing the first terminal 1211 and the second terminal 1221, i.e. connecting and fixing the first wire segment 121 and the second wire segment 122. The connection and disconnection of the first wire segment 121 and the second wire segment 122 are more convenient, and when one of the wire segments is damaged, only the damaged wire segment needs to be replaced, thereby reducing the maintenance cost.

[0052] In an embodiment, as shown in Figure 2 The middle axial motor integrated drive system 100 further includes a wire body limiting structure 3, which is used to limit the adapter wire 12 in the speed reducer 2 and guide the adapter wire 12 from the first side of the speed reducer 2 to the second side of the speed reducer 2, so that the adapter wire 12 does not scatter in the speed reducer shell 21, and is more regular and convenient to maintain.

[0053] Preferably, the wire body limiting structure 3 comprises a limiting hole and a wire pressing plate 31 arranged at one side of the limiting hole, the wire pressing plate 31 is provided with a through hole corresponding to the limiting hole, the limiting hole is located on the arc-shaped communication path between the first side and the second side of the speed reducer 2; the lead wire 12 is arranged in the limiting hole and the through hole and is locked and fixed by the wire pressing plate 31. The lead wire 12 is limited by the limiting hole, the size of the limiting hole is matched with the diameter of the lead wire 12, so that the lead wire 12 is limited in the circumferential direction after being arranged in the limiting hole, so that the lead wire 12 cannot move freely, and the lead wire 12 is arranged in the preset direction, and after passing through the limiting hole, the lead wire 12 is further fixed by the wire pressing plate 31, so that the specified position of the lead wire 12 is fixed in the limiting hole, and the extension direction of the lead wire 12 is guided by the limiting hole.

[0054] Further, after the first lead wire segment 121 is connected with the second lead wire segment 122, the other end of the second lead wire segment 122 can pass out of the limiting hole, so that the part of the second lead wire segment 122 between the limiting hole and the first terminal 1211 is arranged in a straight line.

[0055] Preferably, the lead wire 12 comprises three wire bodies, the limiting hole is provided with three limiting holes, the through hole is provided with three through holes, and the three wire bodies are arranged in the three limiting holes and the three through holes one by one to fix the three wire bodies. Moreover, the wire body limiting structure 3 further comprises a wire clamping block 32, the wire clamping block 32 is connected with the speed reducer 2 and binds the lead wire 12 passing out of the limiting hole in a preset shape, so that the three wire bodies are bound together in parallel when passing out of the speed reducer shell 21, and the three wire bodies are prevented from being irregularly scattered and easily entangled.

[0056] The wire clamping block 32 is arranged in a clamping shape, and the wire clamping block 32 is arranged in a substantially "U" shape. The lead wire 12 is clamped in the U-shaped opening of the wire clamping block 32, and the U-shaped end of the wire clamping block 32 is connected and fixed to the speed reducer shell 21, so as to limit and fix the plurality of wire bodies, and ensure that the lead wire 12 is more regular when passing out of the speed reducer shell 21, so as to be arranged in a certain rule, so that the lead wire 12 is more easily connected to the control device 300, and the lead wire connection error is better avoided.

[0058] In combination Figure 6 and Figure 7 As shown, the frame 200 comprises two frame arms arranged in opposite directions in the transverse direction, and the two frame arms are arranged in the left-right direction when the frame structure assembly 1000 is normally used. The middle axial motor integrated drive system 100 and the control device 300 are located between the two frame arms, and the control device 300 is located in front of the middle axial motor integrated drive system 100. Since the output gear of the middle axial motor integrated drive system 100 is a component connected with the wheel, when placing the middle axial motor integrated drive system 100, the output gear of the middle axial motor integrated drive system 100 is more stable, one side of the output gear is arranged closer to the bottom of the frame 200 and is close to the control device 300. Therefore, when the lead wire 12 of the middle axial motor integrated drive system 100 is drawn out, it is close to one side of the output gear, so as to be better connected to the control device 300.
