[0003] Existing high-efficiency transmission systems for dual-stage drive shaft assemblies in vehicles may have the problem of not being able to effectively stabilize the position of the drive shaft assembly within the transport box. During transportation, components such as the sliding joint, first shaft, bushing, second shaft, and fixed joint may be displaced or collide due to vehicle bumps, resulting in wear and deformation of the component surfaces, and even loosening of the connection parts. To address this, we propose a high-efficiency transmission system for dual-stage drive shaft assemblies in vehicles. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency transmission system for a dual-stage drive shaft assembly in a vehicle, in order to solve the problem mentioned in the background art that the drive shaft assembly may not be able to be effectively stabilized in the transport box. During transportation, components such as the sliding joint, the first shaft, the bushing, the second shaft, and the fixed joint may be displaced or collided due to vehicle bumps, resulting in wear and deformation of the component surfaces, and even loosening of the connection parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency transmission system for a vehicle dual-stage drive shaft assembly, comprising a transport box, a cover plate, screws, and a sliding joint. The screws are threadedly connected to the top of the transport box and the top of the cover plate. A first shaft is fixedly connected to the right end of the sliding joint. A bushing is fixedly connected to the right side of the first shaft. A second shaft is disposed inside the bushing. A fixing joint is fixedly connected to the right side of the second shaft.

[0009] As a preferred embodiment, the front of the transport box is provided with an observation component, the observation component includes a baffle, a groove is formed on the front surface of the transport box, the baffle is slidably connected to the inside of the groove, and a pull block is fixedly connected to the right side of the front of the baffle.

[0010] As a preferred embodiment, a groove is formed on the right side surface of the slide, and magnetic blocks are fixedly connected to the inside of the groove and the right end of the baffle, and the two sets of magnetic blocks are magnetically connected.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By using a fixed assembly and screws to secure the cover plate to the transport box, the spring is compressed to generate elastic force, which drives two sets of rubber pads to adhere to the upper surfaces of the sliding joint and the fixed joint. This longitudinally presses the drive shaft assembly from both ends. The flexible contact of the rubber pads prevents the surfaces of the sliding joint and the fixed joint from being damaged by hard compression, and also limits their vertical movement through friction. Combined with the locking mechanism of the rotating rod, limit block, and limit groove, the pressed state of the rubber pads is fixed, preventing vibration from causing spring failure or component loosening. This ensures that the drive shaft assembly is stably positioned on the sponge pad, achieving reliable fixation and protection, and ensuring the structural integrity and performance after transportation and storage.

[0013] 2. Through the set observation components, the slide groove on the front of the transport box provides a sliding path for the baffle. The staff can pull the pull block to move the baffle along the slide groove, so as to cover or expose the observation area on the front of the transport box. The status of the internal drive shaft assembly can be observed without opening the cover, simplifying the operation process. The groove on the right side of the slide groove cooperates with the magnetic block on the right end of the baffle. The two sets of magnetic blocks are magnetically connected to fix the position of the baffle and prevent it from sliding at will. When not observing, it can reliably cover the observation area to prevent dust and other impurities from entering the interior of the transport box, while protecting the privacy of the internal components.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see the appendix Figure 1 Appendix Figure 2 and appendix Figure 4 - Appendix Figure 7A high-efficiency transmission system for a dual-stage drive shaft assembly for vehicles includes a transport box 1, a cover plate 2, screws 3, and a sliding joint 4. Screws 3 are threadedly connected to the top of the transport box 1 and the top of the cover plate 2. A first shaft 5 is fixedly connected to the right end of the sliding joint 4. A bushing 6 is fixedly connected to the right side of the first shaft 5. A second shaft 7 is disposed inside the bushing 6. A fixing joint 8 is fixedly connected to the right side of the second shaft 7. A fixing assembly 9 is disposed inside the transport box 1. The fixing assembly 9 includes a spring 901, a torsion block 906, and a sponge pad 910. The spring 901 is connected to a metal pressure plate 903, a rubber pad 904, and a connector 905 through a connecting block 902. The torsion block 906 is connected to a limit block 908 through a rotating rod 907. The sponge pad 910 is fixedly installed on the inner bottom wall of the transport box 1. The sliding joint 4, the first shaft 5, the bushing 6, the second shaft 7, and the fixing joint 8 are all disposed on the surface of the sponge pad 910. The upper end of the spring 901 is fixedly connected to the bottom of the cover plate 2.

[0025] Screw 3 enables the transport box 1 and cover plate 2 to be detachably fixed, ensuring that cover plate 2 will not loosen during transportation, and at the same time, it is convenient to disassemble to open transport box 1. Sliding joint 4 is a key transmission component of drive shaft, used to compensate for the angle change and axial displacement between drive shaft and wheel during vehicle operation, ensuring stable power transmission. Its right end is fixedly connected to the first shaft 5 to transmit power to the subsequent shaft.

[0026] The lower end of the spring 901 is fixedly connected to the top of the connecting block 902. The connecting block 902 is fixedly installed on the upper surface of the metal pressure plate 903. The rubber gasket 904 is fixedly connected to the inner wall of the metal pressure plate 903. The inner wall of the rubber gasket 904 is in contact with the upper surface of the first shaft 5. The connecting piece 905 is fixedly connected to the outer wall of the metal pressure plate 903. The lower end of the rotating rod 907 is fixedly connected to the top of the torsion block 906. The limiting block 908 is fixedly connected to the upper surface of the rotating rod 907. Limiting grooves 909 are opened on the top of the connecting piece 905 and the inner bottom wall of the transport box 1. The rotating rod 907 and the limiting block 908 are movably connected to the inside of the limiting grooves 909.

[0027] The operator can rotate the rotating rod 907. When the limiting block 908 corresponds to the limiting groove 909, the locking of the position of the metal pressure plate 903 is released. When the limiting block 908 and the limiting groove 909 intersect, the position of the metal pressure plate 903 is fixed. Some components in the fixing assembly 9 are provided in two sets, including two sets of springs 901, two sets of connecting blocks 902, two sets of metal pressure plates 903 and two sets of rubber pads 904, etc.

[0028] Specifically, by using the fixed component 9 and screws 3 to fix the cover plate 2 and the transport box 1, the spring 901 is compressed to generate elastic force, which drives the two sets of rubber pads 904 to adhere to the upper surfaces of the sliding joint 4 and the fixed joint 8, pressing the drive shaft assembly longitudinally from both ends. The flexible contact of the rubber pads 904 avoids damage to the surfaces of the sliding joint 4 and the fixed joint 8 by hard compression. The friction force restricts its up and down movement. Combined with the locking of the rotating rod 907, the limiting block 908 and the limiting groove 909, the pressed state of the rubber pads 904 is fixed, preventing vibration from causing the spring 901 to fail or the components to loosen. This ensures that the drive shaft assembly is stably positioned on the sponge pad 910, achieving reliable fixation and protection, and ensuring the structural integrity and performance after transportation and storage.

[0029] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 4 Appendix Figure 5 and appendix Figure 8 The front of the transport box 1 is provided with an observation component 10, which includes a baffle 1002. A groove 1001 is provided on the front surface of the transport box 1. The baffle 1002 is slidably connected to the inside of the groove 1001. A pull block 1003 is fixedly connected to the right side of the front of the baffle 1002. A groove 1005 is provided on the right side surface of the groove 1001. A magnetic block 1004 is fixedly connected to the inside of the groove 1005 and the right end of the baffle 1002. The two sets of magnetic blocks 1004 are magnetically connected.

[0030] Pull block 1003 is fixed to the front of baffle 1002 for staff to hold and push baffle 1002 to slide. Two sets of magnetic blocks 1004 are fixed inside groove 1005 and right end of baffle 1002 respectively. The magnetic connection keeps baffle 1002 fixed when it slides to the right side, preventing it from moving at will.

[0031] Specifically, through the observation component 10, the slide 1001 on the front of the transport box 1 provides a sliding path for the baffle 1002. The staff can move the baffle 1002 along the slide 1001 by pulling the pull block 1003, so as to cover or expose the observation area on the front of the transport box 1. The status of the internal drive shaft assembly can be observed without opening the cover plate 2, which simplifies the operation process. The groove 1005 on the right side of the slide 1001 cooperates with the magnetic block 1004 on the right end of the baffle 1002. The two sets of magnetic blocks 1004 are magnetically connected to fix the position of the baffle 1002, preventing it from sliding at will. When not observing, the observation area is covered to prevent dust and other impurities from entering the interior of the transport box 1 and protect the privacy of the internal components.

[0032] Working principle of this utility model: This utility model is a high-efficiency transmission system for a dual-stage drive shaft assembly in a vehicle. First, the operator places the drive shaft assembly, consisting of a sliding joint 4, a first shaft 5, a bushing 6, a second shaft 7, and a fixed joint 8, stably on the surface of the sponge pad 910 on the bottom wall of the transport box 1, ensuring that each component is in close contact with the sponge pad 910. Then, the operator covers the cover plate 2 and uses screws 3 to thread the cover plate 2 to the transport box 1. At this time, the two sets of springs 901 at the bottom of the cover plate 2 are compressed, which drives the metal pressure plate 903 and the rubber pad 904 to move down through the connecting block 902, so that the two sets of rubber pads 904 respectively contact the upper surfaces of the sliding joint 4 and the fixed joint 8, pressing the drive shaft assembly longitudinally from both ends. Then, the operator rotates the torsion block 906, causing the rotating rod 907 to drive the limiting block 908 to rotate until the limiting block 908 intersects with the top of the connecting piece 905 and the limiting groove 909 on the bottom wall of the transport box 1, locking it in place. With the metal pressure plate 903 in position, the rubber gasket 904 is kept pressed. Then, when it is necessary to observe the internal condition, the operator holds the pull block 1003 and pulls the baffle 1002 to the left along the slide 1001, so that the observation area on the front of the transport box 1 is exposed. The condition of the internal drive shaft assembly can be observed without opening the cover plate 2. After observation, the baffle 1002 is pushed to the right until the magnetic block 1004 at the right end of the baffle 1002 is magnetically connected to the magnetic block 1004 in the groove 1005 on the right side of the slide 1001, fixing the baffle 1002 to cover the observation area. When it is necessary to remove the drive shaft assembly, the operator first rotates the torsion block 906 in the opposite direction so that the limit block 908 corresponds to the limit groove 909, releases the lock on the metal pressure plate 903, unscrews the screw 3, opens the cover plate 2, and the spring 901 elastically resets, causing the rubber gasket 904 to disengage from the drive shaft assembly, so that the drive shaft assembly can be removed from the sponge pad 910.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
