[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] Example 1: Figure 1-Figure 4 As shown, the utility model provides a driving shaft assembly connection structure, including an input connecting shaft 1 and an output connecting shaft 2, a first connecting member 3 is installed on the outer surface of the input connecting shaft 1 near the left side, and a plurality of first meshing teeth 31 are equidistantly arranged on the outer surface of the first connecting member 3, a second connecting member 4 is installed on the outer surface of the output connecting shaft 2 near the right side, and a plurality of second meshing teeth 41 are equidistantly arranged on the outer surface of the second connecting member 4, a serpentine spring 5 is matched with the outer surfaces of the first meshing teeth 31 and the second meshing teeth 41, the first meshing teeth 31 and the second meshing teeth 41 are staggered, and a first meshing tooth 31 is installed on the right surface of the first connecting member 3. An anti-dropout sleeve 32, a second anti-dropout sleeve 42 is installed on the left surface of the second connecting member 4, a plurality of first spring steels 33 are arranged between adjacent outer surfaces of the first anti-dropout sleeve 32 and the second anti-dropout sleeve 42, two first protective sleeves 6 are equidistantly installed between adjacent outer surfaces of the input connecting shaft 1 and the output connecting shaft 2, the outer surfaces of the opposite sides of the two first protective sleeves 6 are fixedly connected with a first inner gear ring 61, the outer surface of the first inner gear ring 61 is slidably fitted with a second inner gear ring 63, an elastic inner gear ring 62 is movably connected between the outer surfaces of the first inner gear ring 61 and the second inner gear ring 63, and the outer surface of the second inner gear ring 63 is fixedly connected with a second protective sleeve 64.
[0024] The effect achieved by the entire embodiment 1 is that, when in use, the input connecting shaft 1 and the output connecting shaft 2 are first connected to the driving shaft and the driven shaft respectively. When the driving shaft rotates, the torque is transmitted to the serpentine spring 5 through the first connecting member 3. The design of the serpentine spring 5 enables it to not only effectively absorb the vibration and impact generated by the rotation, but also maintain a stable connection during large swings, thereby ensuring the continuity and reliability of power transmission. When the driving shaft rotates, the first meshing tooth 31 on the first connecting member 3 rotates. At this time, the serpentine spring 5 transmits the torque to the second connecting member 4, driving the second meshing tooth 41 on the second connecting member 4 to rotate, and finally driving the driven shaft to rotate. This design ensures that the drive shaft assembly connection structure has good rigidity while ensuring sufficient strength, and a first spring steel 33 is provided between the first connecting member 3 and the second connecting member 4. The elastic deformation characteristics of the first spring steel 33 can adjust the torque transmission to a certain extent. When the torque suddenly increases, the first spring steel 33 will be deformed to a certain extent to avoid excessive torque being directly transmitted to other fragile components, thereby playing a protective role. The outer surfaces of the first connecting member 3 and the second connecting member 4 are both equipped with a first anti-detachment sleeve 32 and a first anti-detachment sleeve 33. The second anti-dropout sleeve 42 can effectively ensure that the serpentine spring 5 will not fall off from the first connecting piece 3 and the second connecting piece 4. The first anti-dropout sleeve 32 and the second anti-dropout sleeve 42 are made of silicone rubber, which has good elasticity and weather resistance, and can fit the first connecting piece 3 and the second connecting piece 4 tightly, effectively preventing the serpentine spring 5 from falling off under extreme working conditions. This design enhances the stability of the connection and ensures the stable operation of the transmission system. The simple coupling formed by the first inner gear ring 61, the elastic inner gear ring 62 and the second inner gear ring 63 cooperate with each other, which not only further reduces the transmission process. The first protective sleeve 6 and the second protective sleeve 64 effectively prevent foreign matter such as dust, chips, and hard sand from entering the interior of the coupling, reducing the potential damage of these hard particles to the sliding rail surface or precision parts, ensuring the cleanliness and operating efficiency of the transmission system. The drive shaft assembly connection structure shows higher performance and reliability when dealing with large swing angles and large torque transmission requirements, effectively improving the vehicle's driving stability and ride comfort, while extending the service life of the transmission system.
[0025] Example 2: Figure 1-Figure 4 As shown, a plurality of second spring steels 65 are disposed between the outer surfaces of the two first protective sleeves 6 , and the outer surfaces of the plurality of second spring steels 65 all slide through the outer surfaces of the two second protective sleeves 64 .
[0026] The effect achieved by the entire embodiment 2 is that the second spring steel 65 has a certain elasticity, is connected between the two first protective sleeves 6 and passes through the two second protective sleeves 64, and helps to maintain the position and shape of the protective sleeves, thereby enhancing the sealing and protective effects.
[0027] Working principle: When in use, first connect the input connecting shaft 1 and the output connecting shaft 2 to the driving shaft and the driven shaft respectively. When the driving shaft rotates, the torque is transmitted to the serpentine spring 5 through the first connecting member 3. When the driving shaft rotates, the first meshing tooth 31 on the first connecting member 3 rotates. At this time, the serpentine spring 5 transmits the torque to the second connecting member 4, driving the second meshing tooth 41 on the second connecting member 4 to rotate, and finally driving the driven shaft to rotate. A first spring steel 33 is arranged between the first connecting member 3 and the second connecting member 4. When the torque suddenly increases, the first spring steel 33 will undergo a certain deformation to avoid excessive torque being directly transmitted to other fragile parts. The outer surfaces of the first connecting member 3 and the second connecting member 4 are both installed with a first anti-detachment sleeve 32 and a second anti-detachment sleeve 42, which can effectively ensure that the serpentine spring 5 will not fall off the first connecting member 3 and the second connecting member 4. The first anti-detachment sleeve 32 and the second anti-detachment sleeve 42 are made of silicone rubber, which has good elasticity and weather resistance, and can fit tightly with the first connecting member 3 and the second The connecting piece 4 effectively prevents the serpentine spring 5 from falling off under extreme working conditions, and the simple coupling formed by the cooperation of the first inner gear ring 61, the elastic inner gear ring 62 and the second inner gear ring 63 not only further reduces the vibration and impact in the transmission process, but also improves the adaptability and durability of the coupling through the flexible design of the elastic inner gear ring 62. The first protective sleeve 6 and the second protective sleeve 64 effectively block foreign matter such as dust, chips, and hard sand from entering the interior of the coupling, reducing the potential damage of these hard particles to the sliding rail surface or precision components, and ensuring the cleanliness and operating efficiency of the transmission system. The drive shaft assembly connection structure shows higher performance and reliability when dealing with large swing angles and large torque transmission requirements, effectively improving the vehicle's driving stability and ride comfort, while extending the service life of the transmission system. In addition, the second spring steel 65 has a certain elasticity, and is connected between the two first protective sleeves 6 and passes through the two second protective sleeves 64, which helps to maintain the position and shape of the protective sleeves, thereby enhancing the sealing and protection effects.
