[0043] Please refer to Figure 1-Figure 5 The present embodiment provides a driving assembly 1, which includes a first rotating wheel 11, a second rotating wheel 12, a synchronous belt 13, and an auxiliary member 14. The second rotating wheel 12 is spaced apart from the first rotating wheel 11. The synchronous belt 13 rotatably connects the first rotating wheel 11 and the second rotating wheel 12. The auxiliary member 14 is disposed on one side of the synchronous belt 13 and abuts against the synchronous belt 13. The auxiliary member 14 can move relative to the synchronous belt 13 in a direction perpendicular to the extension direction of the synchronous belt 13 (such as Figure 1 The synchronous belt 13 is moved in the direction D to adjust the tension of the synchronous belt 13.

[0044] The drive assembly 1 provided in this embodiment can be applied to multiple fields. This application only illustrates the application of the drive assembly 1 to a vehicle, which does not mean that the drive assembly 1 can only be used in the vehicle field. For example, the drive assembly 1 can also be used in the field of medical equipment, mechanical equipment, industrial logistics transmission, processing equipment, etc.

[0045] The driving assembly 1 provided in this embodiment includes a first rotating wheel 11 and a second rotating wheel 12. The first rotating wheel 11 and the second rotating wheel 12 can rotate. Optionally, the first rotating wheel 11 has a circle of external teeth, and the second rotating wheel 12 has a circle of external teeth. Optionally, the first rotating wheel 11 rotates to drive the synchronous belt 13 to rotate, thereby driving the second rotating wheel 12 to rotate. It can also be understood that the first rotating wheel 11 is a driving wheel and the second rotating wheel 12 is a driven wheel.

[0046] The drive assembly 1 provided in this embodiment also includes a synchronous belt 13. The synchronous belt 13 can directly and rotationally connect the first rotating wheel 11 and the second rotating wheel 12, or can indirectly and rotationally connect the first rotating wheel 11 and the second rotating wheel 12 through other components. Optionally, the synchronous belt 13 is sleeved on the first rotating wheel 11 and the second rotating wheel 12. Optionally, the synchronous belt 13 has a circle of internal teeth, and the internal teeth of the synchronous belt 13 are meshed and connected with the external teeth of the first rotating wheel 11, and are also meshed and connected with the external teeth of the second rotating wheel 12. The extension direction of the synchronous belt 13 is the same as the arrangement direction from the first rotating wheel 11 to the second rotating wheel 12. Among them, the tension of the synchronous belt 13 is a parameter used to describe the compression degree or length adjustment state of the synchronous belt 13 when the drive assembly 1 is in the working state.

[0047] The driving assembly 1 provided in this embodiment further includes an auxiliary member 14. The synchronous belt 13 has an inner side surface and an outer side surface opposite to each other, and the first rotating wheel 11 and the second rotating wheel 12 face the inner side surface of the synchronous belt 13. The auxiliary member 14 is disposed on the outer side of the synchronous belt 13 and abuts against the outer side surface of the synchronous belt 13, or the auxiliary member 14 is disposed on the inner side of the synchronous belt 13 and abuts against the inner side surface of the synchronous belt 13.

[0048] Specifically, the auxiliary part 14 can move along the extension direction perpendicular to the synchronous belt 13. It can also be understood that the auxiliary part 14 can move up and down. As the auxiliary part 14 moves, the auxiliary part 14 can change the position of the synchronous belt 13 by pressing against one end of the synchronous belt 13, thereby adjusting the tension of the synchronous belt 13.

[0049] In summary, in this embodiment, an auxiliary part 14 is provided to support the synchronous belt 13, so that the auxiliary part 14 moves in a direction perpendicular to the extension direction of the synchronous belt 13 to adjust the tension of the synchronous belt 13, so that the synchronous belt 13 remains taut within a preset range and maintains a stable system resistance, thereby improving work efficiency.

[0050] In addition, this embodiment simplifies the adjustment device in the related technology, reduces parts, reduces manufacturing costs, reduces processes and working hours, and optimizes the adjustment method, so that the two rotating wheels can achieve the tensioning effect of the synchronous belt 13 without adjusting the distance.

[0051] Please refer to Figure 1-Figure 5 In one embodiment, the auxiliary component 14 includes a column 141, a protrusion 142 and an elastic portion 143 provided at one end of the column 141 close to the synchronous belt 13, the protrusion 142 abuts against the synchronous belt 13, the elastic portion 143 is sleeved on the column 141, and one end of the elastic portion 143 abuts against the protrusion 142; the driving assembly 1 also includes a support frame 15, one end of the column 141 away from the synchronous belt 13 is passed through the support frame 15, and the other end of the elastic portion 143 abuts against the support frame 15.

[0052] The auxiliary component 14 provided in this embodiment includes a column 141, a protrusion 142 and an elastic portion 143. Optionally, the protrusion 142 is closer to the synchronous belt 13 than the column 141. Optionally, the material of the column 141 includes a hard material such as plastic or metal. Optionally, the width of the column 141 at one end away from the synchronous belt 13 gradually decreases. Optionally, the protrusion 142 and the column 141 are an integrated structure. Optionally, the width of the protrusion 142 is greater than the diameter of the column 141. The elastic portion 143 is sleeved on the column 141, and one end of the elastic portion 143 abuts against the surface of the protrusion 142 away from the synchronous belt 13. The elastic portion 143 can be a spring, and springs of different wire diameters and different lengths can be selected for use according to different tensioning force requirements.

[0053] The drive assembly 1 provided in this embodiment also includes a support frame 15 for supporting the auxiliary component 14. The support frame 15 has a through hole 151, and one end of the column 141 away from the synchronous belt 13 is inserted into the through hole 151, and the through hole 151 passes through the surface of the support frame 15 facing the synchronous belt 13 and the surface of the support frame 15 away from the synchronous belt 13. Optionally, the elastic portion 143 is arranged outside the through hole 151. Optionally, part of the elastic portion 143 is arranged in the through hole 151. Optionally, the other end of the elastic portion 143 abuts against the surface of the support frame 15 facing the synchronous belt 13. Optionally, a stepped surface is provided in the through hole 151, and the other end of the elastic portion 143 abuts against the stepped surface. Optionally, the first rotating wheel 11 and / or the second rotating wheel 12 are arranged on the support frame 15.

[0054] Specifically, the auxiliary component 14 is moved within a certain range through the elastic part 143 to achieve adaptive adjustment of the tension of the synchronous belt 13. The auxiliary component 14 is arranged on the outside of the synchronous belt 13 for schematic illustration. For example, when the synchronous belt 13 is relatively loose, the elastic part 143 stretches, so that the auxiliary component 14 moves toward the direction close to the synchronous belt 13. It can also be understood that the auxiliary component 14 moves upward to compensate for the slack and balance the system tension of the drive component 1. For another example, when the synchronous belt 13 is relatively tensioned, the elastic part 143 is compressed, so that the auxiliary component 14 moves toward the direction away from the synchronous belt 13. It can also be understood that the auxiliary component 14 moves downward to release the tension and balance the system tension of the drive component 1.

[0055] As the tension of the synchronous belt 13 changes, the auxiliary component 14 also moves up and down as the compression amount of the elastic portion 143 changes, thereby achieving a good tensioning effect of elastically tensioning the synchronous belt 13 while keeping the system resistance within an appropriate range.

[0056] In summary, the present embodiment utilizes the auxiliary member 14 composed of the column 141, the protruding portion 142 and the elastic portion 143, and installs the auxiliary member 14 on the support frame 15, so as to realize the adaptive adjustment of the tension of the synchronous belt 13, optimize the adjustment method, and reduce the difficulty of adjustment. In addition, one end of the column 141 is inserted into the support frame 15 to limit the moving direction of the column 141, thereby improving the adjustment reliability of the auxiliary member 14.

[0057] Please refer to Figure 1-Figure 9 In one embodiment, the protrusion 142 includes a connecting sub-portion 1421 provided on the column 141 and a supporting sub-portion 1422 provided on the connecting sub-portion 1421, the supporting sub-portion 1422 abuts against the synchronous belt 13, and the protrusion 142 satisfies one of the following conditions: the extending direction of the supporting sub-portion 1422 is the same as the axial direction of the column 141. It can also be understood that the supporting sub-portion 1422 extends upward. For example, the supporting sub-portion 1422 can be in the form of a roller.

[0058] Alternatively, there is an angle between the extension direction of the support sub-portion 1422 and the axial direction of the column 141. It can also be understood that the support sub-portion 1422 is tilted. Optionally, the angle between the extension direction of the support sub-portion 1422 and the axial direction of the column 141 is an acute angle.

[0059] This embodiment limits the tilting setting of the supporting sub-portion 1422 so that the auxiliary component 14 can reduce the angle between the synchronous belt 13 and the first rotating wheel 11, or the angle between the synchronous belt 13 and the second rotating wheel 12, thereby improving the meshing effect between the synchronous belt 13 and the first rotating wheel 11 and the second rotating wheel 12, and further improving the reliability of the driving component 1.

[0060] In one embodiment, Figure 8 and Fig. 9 As shown, the angle α between the extension direction of the supporting sub-portion 1422 and the axial direction of the column 141 satisfies the following condition: 0°≤α≤45°.

[0061] For example, the angle α between the extension direction of the support sub-portion 1422 and the axial direction of the column 141 may be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, etc. Further optionally, the angle α between the extension direction of the support sub-portion 1422 and the axial direction of the column 141 satisfies the following condition: 10°≤α≤35°; further optionally, the angle α between the extension direction of the support sub-portion 1422 and the axial direction of the column 141 satisfies the following condition: 25°≤α≤30°.

[0062] Please refer to Figure 1-Figure 9 In one embodiment, the protrusion 142 has a supporting surface 1423 that abuts against the synchronous belt 13 , and the supporting surface 1423 is an arc surface that protrudes toward a direction close to the synchronous belt 13 .

[0063] The surface of the supporting sub-portion 1422 of the protruding portion 142 facing the synchronous belt 13 includes a supporting surface 1423, which is protruding toward the direction close to the synchronous belt 13, and the supporting surface 1423 is in an arc shape. Therefore, in this embodiment, by setting the supporting surface 1423 as an arc surface, the auxiliary component 14 is prevented from damaging the synchronous belt 13, thereby improving the reliability of the driving assembly 1.

[0064] Please refer to Figure 1-Figure 9 In one embodiment, the auxiliary component 14 further includes a retaining spring 144 , which is clamped to an end of the column 141 away from the synchronous belt 13 , and the retaining spring 144 is used to support the surface of the support frame 15 away from the synchronous belt 13 .

[0065] The circumferential side surface of the column 141 has a receiving groove 1411 arranged along the circumferential direction of the column 141 , and the receiving groove 1411 is used to receive at least a portion of the clamping spring 144 .

[0066] The auxiliary member 14 provided in this embodiment further includes a snap ring 144, which is clamped on the circumferential side surface of the column 141, and at least part of the snap ring 144 is disposed in the receiving groove 1411. Optionally, the receiving groove 1411 is an annular groove, or the receiving groove 1411 includes a plurality of sub-grooves spaced apart along the circumferential direction of the column 141. The column 141 is inserted into the through hole 151 of the support frame 15, the width of the protrusion 142 is greater than the aperture of the through hole 151, the width of the snap ring 144 is greater than the aperture of the through hole 151, the protrusion 142 is disposed on one side of the through hole 151, and the snap ring 144 is disposed on the other side of the through hole 151.

[0067] Therefore, in this embodiment, the retaining spring 144 is provided so that the retaining spring 144 can abut against the surface of the support frame 15 away from the synchronous belt 13 to limit the position of the column 141, prevent the column 141 from falling out of the through hole 151, and improve the reliability of the drive assembly 1. In addition, the protrusion 142 and the retaining spring 144 can cooperate with each other, limiting the column 141 to be able to move up and down in the through hole 151 and not fall out of the through hole 151.

[0068] The following is an introduction to the assembly method of the driving assembly 1. First, the elastic part 143 is sleeved on the column 141, and one end of the column 141 is inserted into the through hole 151 of the support frame 15, and then the clamping spring 144 is clamped to the column 141 to prevent the column 141 from falling out of the through hole 151. The installation of the auxiliary component 14 is achieved through the above assembly method, and locking and other processes are not required, which is convenient for assembly and disassembly.

[0069] Therefore, the present embodiment optimizes the installation method by providing the retaining spring 144 , and directly inserts the column 141 and then locks the retaining spring 144 , thereby reducing the number of assembly steps and the complexity of installation.

[0070] Please refer to Figure 1-Figure 9 In one embodiment, the support frame 15 has a through hole 151, and one end of the column 141 away from the synchronous belt 13 is inserted into the through hole 151. The shape of the through hole 151 is a cross, and the shape of the column 141 corresponds to the shape of the through hole 151.

[0071] The through hole 151 is in a cross shape, and the column 141 is also in a cross shape. In this embodiment, by setting the shapes of the through hole 151 and the column 141, the movement of the column 141 in the circumferential direction in the through hole 151 is restricted, that is, the rotation of the column 141 is restricted, so that the column 141 can only move in a direction perpendicular to the extension direction of the synchronous belt 13, or in other words, the column 141 can only move up and down, further improving the adjustment reliability of the auxiliary component 14.

[0072] Please refer to Figure 1-Figure 9 In one embodiment, the first rotating wheel 11 drives the second rotating wheel 12 to rotate through the synchronous belt 13; the auxiliary component 14 is closer to the first rotating wheel 11 than the second rotating wheel 12.

[0073] It can also be understood that the first rotating wheel 11 is a driving wheel and the second rotating wheel 12 is a driven wheel. The first rotating wheel 11 rotates to drive the synchronous belt 13 to rotate, thereby driving the second rotating wheel 12 to rotate. The distance between the auxiliary member 14 and the first rotating wheel 11 is smaller than the distance between the auxiliary member 14 and the second rotating wheel 12.

[0074] This embodiment limits the position of the auxiliary component 14 relative to the first rotating wheel 11, which is beneficial to reducing the angle between the synchronous belt 13 and the first rotating wheel 11, thereby improving the meshing effect between the synchronous belt 13 and the first rotating wheel 11 and further improving the reliability of the driving component 1.

[0075] Please refer to Figure 1-Figure 10 The present application also provides a sunshade curtain assembly 2, which includes glass, a sunshade curtain 21 and a driving component 1 as provided above in the present application, wherein the driving component 1 is arranged on the glass, the sunshade curtain 21 is arranged on the glass, and the driving component 1 is used to drive the sunshade curtain 21 to move.

[0076] The sunshade assembly 2 provided in this embodiment adopts the driving component 1 provided in the first aspect of the present application. The driving component 1 is provided with an auxiliary component 14 for supporting the synchronous belt 13, so that the auxiliary component 14 moves in a direction perpendicular to the extension direction of the synchronous belt 13 to adjust the tension of the synchronous belt 13, so that the synchronous belt 13 remains taut within a preset range and maintains a stable system resistance, thereby improving work efficiency.

[0077] The present application also provides a vehicle, comprising a vehicle body and a sunshade assembly as provided in the second aspect of the present application, wherein the sunshade assembly is arranged on the vehicle body.
