[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0031] In order to solve the technical problem of poor labor-saving effect of automobiles in the prior art, the present invention provides a power output device, which can increase the output driving force on the premise of unchanged output power, achieving the effect of labor saving.

[0032] It should be noted that the power output device described in the present utility model is used for but not limited to vehicles and the like. For the convenience of description, in the present utility model, only the case where the power output device is applied to a vehicle is taken as an example for illustration. The principle of applying the power output device to other types of equipment is essentially the same as that applied to a vehicle, and will not be elaborated one by one here.

[0033] In some embodiments, please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of the power output device in an embodiment of the present utility model. The power output device includes a first transmission mechanism 100, a second transmission mechanism 200, and a third transmission mechanism 300. The first transmission mechanism 100 is used to convert the externally input power into a first driving force and a second driving force, wherein the directions of the first driving force and the second driving force are opposite. The second transmission mechanism 200 is connected to the first transmission mechanism 100 and is used to convert the second driving force into a third driving force, and the direction of the third driving force is the same as that of the first driving force. The third transmission mechanism 300 is connected to the first transmission mechanism 100 and the second transmission mechanism 200 and is used to output the combined first driving force and third driving force.

[0034] In this embodiment, by setting the first transmission mechanism 100, the power output device can convert the input power into a first driving force and a second driving force with the same magnitude and opposite directions and output them. Then, in order to achieve the superposition of forces, the direction of the second driving force is changed through the second transmission mechanism 200, and then a third driving force with the same direction as the first driving force is generated. After that, by superimposing the first driving force and the third driving force and outputting them, the driving force output can be increased on the premise that the input power remains unchanged, achieving the effect of saving effort.

[0035] In one of the embodiments, please refer to Figures 1 to 4 , the first transmission mechanism 100 is used to realize the input of external power, and on the one hand, directly output the external power, and on the other hand, convert the external power into a second driving force and output it. Therefore, the first transmission mechanism 100 in the embodiment of the present utility model includes a plurality of transmission parts. Optionally, the first transmission mechanism 100 includes a first transmission part 110, a second transmission part 120, and a third transmission part 130. The first transmission part 110 is connected to the third transmission part 130 through the second transmission part 120. The first transmission part 110 is used to convert the externally input power into a first driving force and output it, and the second transmission part 120 is used to convert the movement of the first transmission part 110 into the movement of the third transmission part 130, so that the third transmission part 130 outputs the second driving force.

[0036] In this embodiment, the first transmission member 110 is configured to receive the power input from an external device. When external power is input, the first transmission member 110 will move under the drive of the power. On the one hand, when the first transmission member 110 moves, it will directly output a first driving force to the third transmission mechanism 300 behind. On the other hand, when the first transmission member 110 moves, it will drive the second transmission member 120 to move, and drive the third transmission member 130 to move through the second transmission member 120, so that the movement direction of the third transmission member 130 is opposite to that of the first transmission member 110, and a second driving force opposite to the direction of the first driving force is output.

[0037] It can be understood that the power input from the outside described in the embodiments of the present utility model can be input through various different devices, such as motors, gears, etc., all of which can drive the first transmission member to move. It should be noted that the embodiments of the present utility model do not limit the power source of the external input, as long as it can drive the first transmission member to move.

[0038] It can be understood that the above technical solution of setting three transmission members is a preferred embodiment of the present utility model. In other embodiments, multiple transmission members can also be provided between the second transmission member and the first transmission member, or between the second transmission member and the third transmission member to achieve smooth driving. As long as the transmission scheme that satisfies the movement directions of the first transmission member and the third transmission member being opposite can be applied to the implementation scheme of the present utility model.

[0039] In one of the embodiments, please continue to refer to Figures 1 to 4 , the first transmission member 110 has a power input end, a power output end, and a power transmission end. The power input end is used for external power input. The power output end is connected to the third transmission mechanism 300 and is used to output the first driving force to the third transmission mechanism 300. The power transmission end is connected to the second transmission member 120 and is used to drive the second transmission member 120 to move.

[0040] In this embodiment, the power input end is used to input external power, the power output end is used to output the generated first driving force to the third transmission mechanism 300, and the power transmission end is used to drive the second transmission member 120 to move, so that the second transmission member 120 can convert the movement of the first transmission member 110 into the movement of the third transmission member 130.

[0041] In one of the embodiments, please continue to refer to Figures 1 to 4 , the first transmission member 110 includes a first gear 111, a power input shaft 112, and a power output shaft (not shown in the figure). The power input shaft 112 is the power input end, the power output shaft is the power output end. The power input shaft 112 and the power output shaft are respectively connected to both sides of the first gear 111. The teeth of the first gear 111 are the power transmission end, and the teeth of the first gear 111 are connected to the second transmission member 120.

[0042] In this embodiment, when external power is input, the power input shaft 112 rotates, and the first gear 111 fixedly connected to the power input shaft rotates accordingly, thereby driving the power output shaft fixedly connected to the first gear 111 to rotate, so that the power output shaft can output a first driving force to the third transmission mechanism 300. At the same time, when the first gear 111 rotates, it will drive the second transmission member 120 connected to its teeth to move, thereby converting the movement of the first gear 111 into the movement of the third transmission member 130.

[0043] It can be understood that there may be intermediate connecting members between the first gear 111, the power input shaft 112, and the power output shaft. For example, bearings are provided between the first gear 111, the power input shaft 112, and the power output shaft, and the friction coefficient between the first gear 111, the power input shaft 112, and the power output shaft is reduced through the bearings to ensure the transmission effect.

[0044] It can be understood that in order to ensure the stability of the first gear 111 during rotation, the first transmission member 110 further includes a gear mounting bracket 113. The gear mounting bracket 113 is connected to the first gear 111 and the power input shaft 112, and then drives the first gear 112 to move through the power input shaft, and then drives the gear mounting bracket 113 to rotate synchronously through the first gear 113.

[0045] In one embodiment, please continue to refer to Figures 1 to 4 , the second transmission member 120 includes planetary gears 121. The planetary gears 121 are all arranged between the first gear 111 and the third transmission member 130. One side of the planetary gear 121 meshes with the first gear 111, and the other side of the planetary gear 121 is connected to the third transmission member 130.

[0046] In this embodiment, the first gear 111 and the third transmission member 130 are connected by the planetary gears 121. When the first gear 111 rotates, the planetary gears 121 will be driven to rotate. When the planetary gears 121 rotate, they will drive the third transmission member 130 to move, thereby enabling the third transmission member 130 to output a second driving force opposite to the first driving force.

[0047] In one embodiment, in order to ensure the stability of the planetary gear installation, the second transmission member 120 further includes a planet carrier 122. The planetary gears 121 are installed on the planet carrier 122. The planet carrier 122 may have several installation positions, and several planetary gears 121 are respectively installed in one installation position.

[0048] In one embodiment, the number of planetary gears 121 is at least two, which can ensure the stability of power transmission. Optionally, the number of planetary gears 121 can be two, three, four, etc., and the embodiments of the present utility model do not limit this.

[0049] In one embodiment, please continue to refer to Figures 1 to 4 , the third transmission member 130 includes a first gear ring 131 and a second gear ring 132. The first gear ring 131 and the second gear ring 132 are connected and coaxially arranged. The first gear ring 131 has internal teeth 131a meshing with the planetary gears 121, and the second gear ring 132 has external teeth 132a connected to the second transmission mechanism 200.

[0050] In this embodiment, the connection between the planetary gears 121 and the second transmission mechanism 200 is achieved through two gear rings. On the one hand, the internal teeth 131a of the first gear ring 131 will convert the movement of the planetary gears 121 into the rotation of the first gear ring 131, and make the rotation direction of the first gear ring 131 opposite to the transmission direction of the first gear 111. On the other hand, when the first gear ring 131 rotates, it will drive the second gear ring 132 to rotate. The external teeth 132a of the second gear ring 132 will convert the movement of the second gear ring 132 into the movement of the second transmission mechanism 200, and further make the second transmission mechanism 200 drive the third transmission mechanism 300 to move. Exemplarily, when the first gear 111 rotates in the clockwise direction, it will drive the planetary gears 121 to rotate in the counterclockwise direction. When the planetary gears 121 rotate counterclockwise, they will drive the first gear ring 131 to rotate counterclockwise. When the first gear ring 131 rotates counterclockwise, it will drive the second gear ring 132 to rotate synchronously counterclockwise, thereby realizing the function that the rotation direction of the second gear ring 132 is opposite to that of the first gear 111.

[0051] In one of the embodiments, in order to ensure that the second gear ring 132 can correctly output the driving force to the subsequent third transmission mechanism 300, so that the directions of the first driving force and the third driving force received by the third transmission mechanism are the same, the second gear ring 132 is a bevel gear ring, which can realize the transmission in the vertical direction. For example, when the second gear ring 132 rotates in the vertical direction, the second transmission mechanism 200 can rotate in the horizontal direction, and then transmit the driving force to the rear.

[0052] It can be understood that the above-described manner of setting two ring gears is a preferred embodiment of the third transmission member 130 of the present invention. In other embodiments, other implementation manners may be adopted to achieve that the movement direction of the third transmission member 130 is opposite to the movement direction of the first transmission member 110. For example, the third transmission member 130 includes a ring gear having internal teeth and external teeth. The internal teeth of the ring gear mesh with the planetary gear 121, and the external teeth of the ring gear are connected to the second transmission mechanism 200, which can also achieve the output of the second driving force in the direction opposite to the direction of the first driving force. Therefore, as long as the transmission scheme that satisfies the movement directions of the first transmission member 110 and the third transmission member 130 being opposite can be applied to the implementation scheme of the present invention.

[0053] In the embodiment of the present invention, the first transmission mechanism 110 draws on the transmission manner of the planetary gear transmission device. Different from the planetary gear transmission device, in the planetary gear transmission device, the planetary carrier is often fixed and the ring gear rotates, or the planetary carrier rotates and the ring gear is fixed. However, in the embodiment of the present invention, the first gear 111, the first ring gear 131, and the second ring gear 132 all rotate. Therefore, the output of two forces in different directions can be achieved.

[0054] It can be understood that the first transmission member 110, the second transmission member 120, and the third transmission member 130 described in the present invention are power components for realizing the main functions of the present invention. Of course, as Figure 3 shown, in specific implementation, in order to prevent the first transmission member 110, the second transmission member 120, and the third transmission member 130 from being damaged, the first transmission mechanism 100 can be integrally installed in a housing 400.

[0055] In one of the embodiments, please continue to refer to Figure 1 , the second transmission mechanism 200 includes bevel gears 210. One side of the bevel gears 210 meshes with the second ring gear 132, and the other side of the bevel gears 210 is connected to the third transmission mechanism 300.

[0056] In this embodiment, the change in the rotation direction is achieved through the bevel gears 210. When the second ring gear 132 rotates, the bevel gears 210 will rotate accordingly, and when the bevel gears 210 rotate, they will drive the transmission mechanism 300 connected to the other side of the bevel gears 210 to rotate. Since the rotation directions of the rotation mechanisms meshed on both sides of the bevel gears 210 must be the same, the second driving force can be changed into a third driving force with the opposite direction.

[0057] In one of the embodiments, the number of bevel gears 210 is at least two, which can ensure the stability of power transmission. Optionally, the number of bevel gears 210 can be two, three, four, etc. The embodiment of the present invention does not limit this. Preferably, the number of bevel gears 210 is four, and the four bevel gears are distributed in a circumferential array.

[0058] In one embodiment, to ensure that the force can be transmitted to the third transmission mechanism to the greatest extent, the mating angle between the bevel gear 210 and the second gear ring 132 is 90°, that is, the axis of the bevel gear 210 is perpendicular to the axis of the second gear ring 132, so that the third transmission mechanism 300 can receive the third driving force in the same direction as the first driving force to the greatest extent.

[0059] To achieve stable transmission of the bevel gear 210, optionally, the second transmission mechanism 200 further includes a mounting seat 220, and a plurality of bevel gears 210 are mounted on the mounting seat 220. Among them, the mounting seat 220 has a plurality of mounting positions for mounting one bevel gear respectively. For example, the mounting seat 220 is provided with a plurality of shaft holes, and the rotating shaft of the bevel gear 210 is mounted in the shaft holes. In addition, it should be noted that in order to allow the power output shaft to pass through, a through hole is formed on the mounting seat 220 for the power output shaft to pass through and then connect to the third transmission mechanism 300. It can be understood that the axle of the bevel gear 220 can be mounted in the housing 400, thereby ensuring that the bevel gear 200 can rotate under the drive of the second gear ring 132.

[0060] In one embodiment, please continue to refer to Figure 1 , the third transmission mechanism 300 includes a second gear 310 and a gear shaft 320. The second gear 310 is a bevel gear. The second gear 310 meshes with the bevel gear 210. One side of the second gear 310 is connected to the power output shaft, and the other side of the second gear 310 is connected to the gear shaft 320.

[0061] In this embodiment, by providing the second gear 310 with helical teeth, when the bevel gear 210 rotates, the second gear 310 will follow and rotate, and the rotation direction is opposite to that of the second gear ring 132. At the same time, the second gear 310 will also rotate under the drive of the power output shaft. Therefore, the second gear 310 has two power sources and can achieve higher-speed rotation or output a greater torque under the action of the same input power.

[0062] It can be understood that the power output device described in the present invention can be applied to the transmission structures of equipment such as airplanes, automobiles, and machine tools, and can greatly save the energy consumption of such equipment.

[0063] To better understand the present invention, the technical solutions of the present invention will be described in detail below in conjunction with Figures 1 to 2 :

[0064] When the power input shaft 112 has power input, it drives the first gear 111 to rotate. On the one hand, after the first gear 111 generates a first driving force in the clockwise direction based on the input power, it outputs the first driving force to the second gear 310 through the power output shaft. Under the action of the first driving force, the second gear 310 has a tendency to rotate in the clockwise direction. On the other hand, when the first gear 111 rotates, it drives each planetary gear 121 to rotate. When each planetary gear 121 rotates, it drives the first ring gear 131 to rotate. When the first ring gear 131 rotates, it drives the second ring gear 132 to rotate synchronously, so that the second ring gear 132 generates a second driving force in the counterclockwise direction. The bevel gear 210 engaged with the second ring gear 132 rotates under the action of the second driving force. When the bevel gear 210 rotates, it will output a third driving force. The second gear 310 engaged with the other side of the bevel gear 210 will have a tendency to rotate in the clockwise direction under the action of the third driving force. Therefore, the first driving force and the third driving force will combine to drive the second gear 310 to rotate clockwise, thereby achieving the effect of increasing the output driving force and saving effort on the premise that the input power remains unchanged.

[0065] Based on the above power output device, the present utility model also correspondingly provides an automobile, including the power output device described in each of the above embodiments, which can output a greater torque on the premise of inputting the same power, achieving the effect of saving effort. Since the power output device has been described in detail above, it will not be elaborated here.

[0066] It can be understood that in an automobile, the number of power output devices can be multiple, and the first transmission mechanism 100 of two adjacent power output devices is connected to the third transmission mechanism 300. That is to say, the first transmission mechanism 100 of the previous power output device is connected to the third transmission mechanism 300 of the next power output device, thereby realizing the orderly transmission of power and being able to save more effort.

[0067] In summary, for the power output device and the automobile provided by the present utility model, by setting the first transmission mechanism, the input power can be converted into two first driving forces and second driving forces with the same magnitude and opposite directions and output. Then, in order to achieve the superposition of forces, the direction of the second driving force is changed through the second transmission mechanism, thereby generating a third driving force with the same direction as the first driving force. After that, the first driving force and the third driving force are superimposed and output, so that the output driving force can be increased on the premise that the input power remains unchanged, achieving the effect of saving effort.

[0068] The specific implementation manners of the present utility model described above do not constitute a limitation to the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model should be included in the protection scope of the claims of the present utility model.
