[0032] Reference below Figures 1 to 6 The driving assembly 1000 and the automobile model having the same according to the embodiment of the present invention are described.

[0033] like Figures 2 to 5 As shown, the drive assembly 1000 according to the embodiment of the first aspect of the utility model includes: a first output component, a second output component and a drive mechanism 300, the first output component includes a first rotating shaft 100, one end of the first rotating shaft 100 is provided with a first coupling structure 150, the first coupling structure 150 is used to connect the first transmission shaft component 910, and the other end is coaxially fixed with a first steering gear 110; the second output component includes a second rotating shaft 200, one end of the second rotating shaft 200 is coaxially fixed with a second steering gear 210, and the other end is provided with a second connecting structure, the second coupling structure 220 is used to connect the second transmission shaft component 920, the second steering gear 210 and the first steering gear 110 are meshed with each other and distributed up and down, and the axis lines of the second rotating shaft 200 and the first rotating shaft 100 are located in the same vertical plane; the output end of the drive mechanism 300 is transmission-connected to the first rotating shaft 100, and is used to drive the first rotating shaft 100 to rotate.

[0034] It can be understood that the drive assembly 1000 includes a first output component, a second output component and a drive mechanism 300, the first output component includes a first rotating shaft 100, the second output component includes a second rotating shaft 200, one end of the first rotating shaft 100 is fixedly provided with a first steering gear 110, one end of the second rotating shaft 200 is fixedly provided with a second steering gear 210, the first steering gear 110 and the second steering gear 210 are meshed and connected, the other end of the first rotating shaft 100 is connected to the first transmission shaft component 910 through the first coupling structure 150, and the other end of the second rotating shaft 200 is connected to the second transmission shaft component 920 through the second coupling structure 220, so when the drive mechanism 300 drives the first rotating shaft 100 to rotate, the first rotating shaft 100 can be sequentially connected through the first steering gear 110 and The second steering gear 210 drives the second rotating shaft 200 to rotate in the opposite direction, so that the first transmission shaft assembly 910 connected to the other end of the first rotating shaft 100 and the second transmission shaft assembly 920 connected to the other end of the second rotating shaft 200 have opposite rotation directions, thereby balancing the torque and improving the stability of the entire drive assembly 1000; at the same time, the first rotating shaft 100 and the second rotating shaft 200 are distributed up and down, and the axis lines of the first rotating shaft 100 and the second rotating shaft 200 are located in the same vertical plane, so that the entire drive assembly 1000 occupies less space in the horizontal direction, thereby improving space utilization, and can reduce the design specifications of the product after being applied to other products such as automobiles; therefore, the drive assembly 1000 of the present application can balance the torque, improve stability during use, and improve space utilization.

[0035] Among them, one end of the first coupling structure 150 of the first rotating shaft 100 and one end of the second coupling structure 220 of the second rotating shaft 200 are respectively facing the front and rear directions, so that when the driving mechanism 300 drives to rotate, the first transmission shaft assembly 910 and the second transmission shaft assembly 920 rotate in opposite directions. After the torque is balanced, the stability will be improved.

[0036] It can be understood that it also includes a housing 1100 and an adjusting mechanism 500, the adjusting mechanism 500 and the driving mechanism 300 are respectively fixed to the housing 1100, and the adjusting mechanism 500 is connected to the first output component and is used to adjust the speed of the first rotating shaft 100. For example, Figure 2 As shown, in this embodiment, the drive assembly 1000 also includes a shell 1100 and an adjusting mechanism 500. The adjusting mechanism 500 is connected to the first rotating shaft 100 and is used to adjust the rotation speed of the first rotating shaft 100, thereby enabling the change of the rotation speed of the first transmission shaft assembly 910 and the second transmission shaft assembly 920. In addition, the adjusting mechanism 500 and the drive mechanism 300 are respectively fixed to the shell 1100, thereby forming an integral drive assembly 1000.

[0037] It is understandable that the center of gravity of the drive assembly 1000 is located on the vertical plane where the second rotating shaft 200 and the first rotating shaft 100 are located. Figure 3 As shown, in this embodiment, the first rotating shaft 100 and the second rotating shaft 200 rotate in opposite directions, and the center of gravity of the driving assembly 1000 is located on the vertical plane where the axis lines of the first rotating shaft 100 and the second rotating shaft 200 are located. Therefore, the overall balance of the driving assembly 1000 can be further improved.

[0038] It can be understood that the driving mechanism 300 includes a driving component 310 and a transmission gear set, the first rotating shaft 100 is sleeved with a first gear 120 and a second gear 130, the transmission gear set is respectively connected to the first gear 120 and the second gear 130, the driving component 310 drives the first gear 120 and the second gear 130 to rotate respectively through the transmission gear set, the first rotating shaft 100 is slidably sleeved with a sliding sleeve 140, the sliding sleeve 140 is located between the first gear 120 and the second gear 130, and protrusions 141 are respectively provided at both ends, the first gear 120 and the second gear 130 are correspondingly provided with grooves 121 for the protrusions 141 to be embedded, the adjustment mechanism 500 is connected to the sliding sleeve 140, and is used to drive the sliding sleeve 140 to slide, so that the sliding sleeve 140 is embedded in the first gear 120 or the second gear 130. For example, Figure 3 , Figure 4 As shown, in this embodiment, the driving mechanism 300 includes a driving component 310 and a transmission gear set, which are respectively meshed and connected with the first gear 120 and the second gear 130, and can drive the first gear 120 and the second gear 130 to rotate under the drive of the driving component 310. At the same time, the adjustment mechanism 500 can drive the sliding sleeve 140 to embed into the first gear 120 or the second gear 130. When the sliding sleeve 140 is embedded in the first gear 120, the first rotating shaft 100 will rotate at the speed of the first gear 120, and when the sliding sleeve 140 is embedded in the second gear 130, the first rotating shaft 100 will rotate at the speed of the second gear 130.

[0039] It should be understood that the first gear 120 and the second gear 130 are respectively sleeved on the first rotating shaft 100, but do not rotate with the rotation of the first rotating shaft 100. The sliding sleeve 140 can slide along the axis of the first rotating shaft 100, and the internal shape of the sliding sleeve 140 is adapted to the outer peripheral shape of the first rotating shaft 100, so as to drive the first rotating shaft 100 to rotate. When the sliding sleeve 140 is engaged with one of the first gear 120 and the second gear 130, it can rotate with the engaged gear and drive the first rotating shaft 100 to rotate. The first gear 120 and the second gear 130 have different rotation speeds due to the separate transmission of the transmission gear set.

[0040] It can be understood that the first gear 120 and the second gear 130 are provided with a first guide surface 122, and the protrusion 141 is correspondingly provided with a second guide surface 142, and the first guide surface 122 is located between the end surface of the first gear 120 / the second gear 130 and the inner side wall of the groove 121, so that the protrusion 141 slides into the groove 121. Figures 4 to 5 As shown, in this embodiment, the sliding sleeve 140 is located between the first gear 120 and the second gear 130, and protrusions 141 are respectively provided at both ends of the sliding sleeve 140, and a second guide surface 142 is provided at the edge of the protrusion 141. A first guide surface 122 is provided between the end surface of the first gear 120 / the second gear 130 and the inner side wall of the groove 121. The setting of the first guide surface 122 enables the protrusion 141 of the sliding sleeve 140 to slide smoothly into the groove 121, which is convenient for alignment and sliding in, thereby reducing the wear between the sliding sleeve 140 and the first gear 120 / the second gear 130.

[0041] It can be understood that the adjustment mechanism 500 includes a second driving member 510, a connecting rod 520 and a toggle member 530, the connecting rod 520 is connected to the toggle member 530, the output end of the second driving member 510 is connected to the connecting rod 520, and the toggle member 530 can be driven by the connecting rod 520 to drive the sliding sleeve 140 to slide. Figures 4 to 5 As shown, in this embodiment, the adjustment mechanism 500 includes a second driving member 510, a connecting rod 520 and a toggle member 530 connected in sequence, and the toggle member 530 is connected to the sliding sleeve 140. When in use, the second driving member 510 drives the toggle member 530 to slide through the connecting rod 520, so that the toggle member 530 can drive the sliding sleeve 140 to slide between the first gear 120 and the second gear 130, thereby realizing the gear shifting of the first rotating shaft 100.

[0042] It can be understood that the transmission gear set includes a third rotating shaft 320 and a fourth rotating shaft 330, the third rotating shaft 320 is sleeved with a third gear 321 and a fourth gear 322, the fourth rotating shaft 330 is sleeved with a fifth gear 331 and a sixth gear 332, the fifth gear 331 is respectively meshed with the third gear 321, the fourth gear 322 and the first gear 120, the sixth gear 332 is respectively meshed with the second gear 130 and the fourth gear 322, the third gear 321, the fourth gear 322 and the fifth gear 331 are all composite gears, and the output end of the driving assembly 310 is connected to the third gear 321 and is used to drive the third gear 321 to rotate. For example, Figure 3As shown, in this embodiment, the transmission gear set includes a third rotating shaft 320 and a fourth rotating shaft 330, the third rotating shaft 320 is sleeved with a third gear 321 and a fourth gear 322, and the fourth rotating shaft 330 is sleeved with a fifth gear 331 and a sixth gear 332. When in use, the output end of the driving component 310 is connected to the third gear 321, thereby driving the third gear 321 to rotate, the third gear 321 is meshed with the fifth gear 331, and the fifth gear 331 is meshed with the first gear 120, so that the third gear 321 can drive the first gear 120 to rotate through the fifth gear 331, and the fifth gear 331 is a composite gear, the fifth gear 331 is meshed with the fourth gear 322, and the fourth gear 322 is meshed with the sixth gear 332, so the fifth gear 331 drives the sixth gear 332 to rotate through the fourth gear 322, and the sixth gear 332 is meshed with the second gear 130, thereby driving the second gear 130 to rotate.

[0043] It should be understood that the third gear 321, the fourth gear 322 and the fifth gear 331 are all compound gears. Therefore, after the driving assembly 310 drives the large gear of the third gear 321 to rotate, the small gear of the third gear 321 drives the large gear of the fifth gear 331 to rotate, the small gear of the fifth gear 331 drives the large gear of the fourth gear 322 to rotate, and the small gear of the fourth gear 322 drives the sixth gear 332 to rotate. Therefore, the rotation speed of the first gear 120 is greater than the rotation speed of the second gear 130.

[0044] like Figure 1 , Figure 6 As shown, the automobile model according to the second embodiment of the utility model includes the drive assembly 1000 of the first embodiment mentioned above.

[0045] It can be understood that this car model includes the drive assembly 1000 in the first aspect embodiment. Therefore, this car model can balance the torque and is relatively stable during driving. Moreover, since the first rotating shaft 100 and the second rotating shaft 200 are located in the same vertical plane, space in the width direction can be saved, and the specifications of the car model can be made smaller to meet the different needs of customers in the market.

[0046] It can be understood that the vehicle frame 600, the front axle 700, the rear axle 800, the first transmission shaft assembly 910 and the second transmission shaft assembly 920 are also included. The drive assembly 1000 is arranged on the vehicle frame 600, the first rotating shaft 100 is connected to the front axle 700 through the first transmission shaft assembly 910, and the second rotating shaft 200 is connected to the rear axle 800 through the second transmission shaft assembly 920. For example, Figures 1 to 6As shown, in this embodiment, the drive assembly 1000 is arranged on the frame 600, the first rotating shaft 100 is connected to the front axle 700 through the first transmission shaft assembly 910, and the second rotating shaft 200 is connected to the rear axle 800 through the second transmission shaft assembly 920, thereby realizing four-wheel drive.

[0047] It is understandable that the vertical plane passing through the axis of the first rotating shaft 100 and the second rotating shaft 200 is located in the middle of the frame 600 and is perpendicular to the axis of the front axle 700 and the axis of the rear axle 800. Figure 6 As shown, in this embodiment, the vertical plane passing through the axis of the first rotating shaft 100 and the second rotating shaft 200 is located in the middle of the frame 600 and is perpendicular to the axis of the front axle 700 and the rear axle 800. Therefore, the drive assembly 1000 can output power in a more balanced manner, thereby improving the balance of the entire car model.

[0048] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
