[0003] For example, certain components in industrial equipment, automotive transmission systems, and aerospace applications require extremely high strength and stability in their connection structures. Currently, common internal tube connection transmission structures mainly consist of bolted and welded connections. During high torque transmission, bolted connections are prone to failure due to excessive force on the bolts, while welded connections may experience thermal stress during welding, leading to material deformation and affecting the reliability and stability of the connection structure. Furthermore, during transmission, the connection structure itself generates vibration and impact, potentially causing damage.

[0004] Therefore, there is an urgent need for an inner tube connection transmission structure to solve the above problems. Utility Model Content

[0036] like Figures 1-4 As shown, in this embodiment, the inner tube connection transmission structure includes a tube wall 1, a connector 2, a mating component 3, and a fixing component 4. The tube wall 1 has a fixing hole 11. The connector 2 is disposed within the tube wall 1 and includes a force-transmitting part 21 and an elastic part 22. The elastic part 22 has a groove 221, and the force-transmitting part 21 is embedded in the groove 221 and is used to connect with the transmission end of the transmission mechanism. Along the circumferential direction of the tube wall 1, the mating component 3 is disposed between the tube wall 1 and the elastic part 22. The inner ring of the mating component 3 abuts against the outer circumference of the elastic part 22, and the outer ring of the mating component 3 abuts against the inner circumference of the tube wall 1. The mating component 3 has a fixing groove 31. One end of the fixing component 4 is engaged with the fixing groove 31, and the other end of the fixing component 4 is engaged with the fixing hole 11.

[0037] The tube wall 1 is laser-formed, allowing for precise control of its shape and dimensions, ensuring high strength and accuracy to meet the demands of high torque transmission. Along the outer periphery to the center of the tube wall 1, a mating component 3, an elastic part 22, and a force-transmitting part 21 are sequentially embedded within it. The force-transmitting part 21 is embedded within a groove 221 of the elastic part 22, and has a mounting hole 211 for connecting to the transmission end of the force-transmitting mechanism. The drive shaft of the motor is mounted within the mounting hole 211. The elastic part 22 is designed as a soft rubber pad, with its inner ring pressing against the outer periphery of the force-transmitting part 21 and its outer ring pressing against the inner periphery of the mating component 3. Along the circumferential direction of the tube wall 1, the elastic component is sandwiched between the force-transmitting part 21 and the mating component 3, reducing vibration and impact. Furthermore, the elastic part 22 possesses excellent elasticity, absorbing and buffering vibration and impact energy generated during transmission, protecting the connection structure from damage, and also contributing to improved connection stability. Along the circumferential direction of the pipe wall 1, the mating component 3 is clamped between the pipe wall 1 and the elastic part 22. The fixing component 4 is set as a pin block and is installed in the fixing groove 31 of the mating component 3 to achieve high torque transmission. The design of the mating component 3 and the fixing component 4 are mutually compatible. Through precise assembly process, a tight fit between the two is ensured, thereby effectively transmitting high torque. The fixing component 4 is engaged with the fixing hole 11 of the pipe wall 1 by pressing. The design of the fixing component 4 can provide a large contact area and enhance the stability of the connection. By pressing the fixing component 4 and assembling the mating component 3, the pipe wall 1 reliably transmits high torque, meeting various application scenarios with high torque requirements and improving the reliability and stability of the connection structure.

[0038] Continue to refer to Figures 1-4 The fastener 4 includes two fixing parts 41 and a middle part 42. The two fixing parts 41 are respectively connected to the two ends of the middle part 42. Along the circumferential direction of the pipe wall 1, the width of the fixing part 41 is greater than the width of the middle part 42. The middle part 42 is located at the opening of the fixing groove 31. The two fixing parts 41 can be respectively engaged with the fixing groove 31 and the fixing hole 11. The longitudinal cross-section of the fixing groove 31 is convex. The fixing groove 31 includes an opening part 311 and a main body part 312. The width of the main body part 312 is greater than the width of the opening part 311. The main body part 312 is configured to engage with the fixing parts 41, and the opening part 311 is configured to slidably engage with the middle part 42. Along the length direction of the fixing groove 31, the middle part 42 and one of the fixing parts 41 of the fastener 4 slide and engage with the opening part 311 and the main body part 312 respectively, and the other fixing part 41 engages with the fixing hole 11 of the pipe wall 1 by pressing. The fastener 4 ensures a tight fit between the pipe wall 1 and the mating part 3, thereby effectively and reliably transmitting high torque, meeting various application scenarios with high torque requirements, and improving the reliability and stability of the connection structure.

[0039] Preferably, there are multiple fixing members 4, fixing grooves 31, and fixing holes 11. Along the circumferential direction of the pipe wall 1, multiple fixing holes 11 are spaced apart and correspond one-to-one with multiple fixing grooves 31. Multiple fixing members 4 are snapped into the corresponding fixing holes 11 and fixing grooves 31. In this embodiment, there are four fixing members 4, and correspondingly four fixing grooves 31 and fixing holes 11. The four fixing members 4 are snapped into the fixing grooves 31 of the mating parts 3 of the fixing holes 11 of the pipe wall 1 by pressing, further improving the stability and reliability of the connection structure.

[0040] Reference Figure 2 and Figure 3 The force transmission part 21 has a protrusion 23 on its outer periphery, and a positioning part 222 on the inner sidewall of the groove 221. The protrusion 23 is engaged with the inner side of the positioning part 222. The mounting hole 211 of the force transmission part 21 has a polygonal cross-sectional shape and is used to install the transmission end of the transmission mechanism. There are multiple protrusions 23 and positioning parts 222. Along the circumferential direction of the pipe wall 1, multiple protrusions 23 are spaced apart, and multiple positioning parts 222 are configured to engage with each of the multiple protrusions 23 in a one-to-one manner. The force transmission part 21 is securely installed in the groove 221 of the elastic part 22 by the engagement of multiple protrusions 23 with multiple positioning parts 222, thus reliably transmitting high torque.

[0041] Reference Figure 2 The inner ring of the mating component 3 has multiple recesses 32. Along the circumferential direction of the pipe wall 1, these recesses 32 are spaced apart and respectively engage with the outer sides of multiple positioning parts 222. The engagement of the mating component 3 with the outer sides of the multiple positioning parts 222 through the multiple recesses 32 ensures that the mating component 3 and the elastic part 22 are firmly fixed together, resulting in a secure installation. The elastic part 22 reduces vibration and impact. Furthermore, it absorbs and buffers the vibration and impact energy generated during transmission, protecting the connection structure from damage and also contributing to improved connection stability.

[0042] Continue to refer to Figure 2 Along the axial direction of the pipe wall 1, a limiting part 223 is provided on the outer edge of one end of the elastic part 22. The limiting part 223 can abut against the end face of the mating part 3 to prevent the elastic part 22 from moving along the axial direction of the pipe wall 1 during the transmission of high torque, thereby affecting the reliability and stability of the connection structure.

[0043] Continue to refer to Figure 2 The mating component 3 is also provided with multiple through holes 33. The multiple through holes 33 are spaced apart along the circumference of the pipe wall 1. While ensuring the structural strength of the mating component 3 itself, it can prevent the mating component 3 from cracking during the transmission of high torque. The through holes 33 play the role of dispersing stress.
