Figure 2 As shown, the drive mechanism 4 includes a housing 41, a first gear 42, a second gear 43, a third gear 44, and a motor 45. The housing 41 is bolted to the lower part of the upper rail 1. The first gear 42, second gear 43, and third gear 44 are rotatably mounted inside the housing 41 to form a gearbox. The motor 45 is bolted to the gearbox outside the housing 41. The output shaft of the motor 45 is connected to the first gear 42. The third gear 44 is connected to the first gear 42 via the second gear 43 and has an internal thread that meshes with the lead screw 3. Thus, the motor 45 drives the gearbox, and transmission is achieved through the meshing of the gearbox with the lead screw 3. In this embodiment, the output torque of the motor 45 is amplified by a two-stage gear reduction, allowing the motor 45 to be made smaller, which is beneficial for saving space. Specifically, as... Figure 3 As shown, the motor 45 is installed parallel to the lead screw 3 and connected to the inner side of the upper rail 1 and the lower rail 2 along with the gearbox, which can reduce noise transmission and provide more space for the upper hand parts.

[0051] like Figure 4As shown, the difference between the center console assembly of the second preferred embodiment of this utility model and the first preferred embodiment lies only in the drive mechanism 4a, as... Figure 5 As shown, the drive mechanism 4a includes a housing 41a, a buffer 42a, and a stepper motor 43a. The housing 41a is bolted to the lower part of the upper rail 1. The stepper motor 43a is mounted inside the housing 41a via the buffer 42a and has an internal thread that directly meshes with the lead screw 3. The rotational motion of the stepper motor 43a is directly transmitted to the lead screw 3, achieving precise linear transmission. In this embodiment, the buffer 42a is a rubber component used for cushioning to reduce vibration and noise, and improve smoothness and durability. In this embodiment, the output torque of the stepper motor 43a connected to the lower part of the upper rail 1 directly meshes with the lead screw 3 fixed to the lower rail 2 via its internal thread, achieving efficient transmission and locking functions, and a simple structure. In particular, as shown... Figure 6 As shown, the stepper motor 43a is directly mounted on the lead screw 3 and connected to the inner side of the upper rail 1 and the lower rail 2, which can reduce noise transmission and leave more space above the upper rail 1 to arrange the counters.

[0052] like Figure 7 As shown, the difference between the center console assembly of the third preferred embodiment of this utility model and the first preferred embodiment lies only in the drive mechanism 4b, as... Figure 8 As shown, the drive mechanism 4b includes a first housing 41b, a first gear 42b, a second gear 43b, a flexible shaft 44b, a second housing 45b, a third gear 46b, a fourth gear 47b, and a motor 48b. The first housing 41b is bolted to the upper rail 1. The first gear 42b and the second gear 43b are rotatably mounted inside the first housing 41b to form a first gearbox. The second housing 45b is bolted to the lower part of the upper rail 1. The third gear 46b and the fourth gear 47b are rotatably mounted inside the first housing 45b. A second gearbox is formed on the housing 45b. The first and second gearboxes are connected by a flexible shaft 44b. The motor 48b is connected to the first gearbox by bolts. The output shaft of the motor 48b is connected to the second gear 43b via the first gear 42b. The fourth gear 47b is connected to the second gear 43b via the third gear 46b and the flexible shaft 44b, and has an internal thread that meshes with the lead screw 3. Thus, the rotational motion of the motor 48b changes direction through the first gearbox, and is then transmitted to the second gearbox via the flexible shaft 44b, where it meshes with the lead screw 3 to achieve transmission. In this embodiment, the third gear 46b and the fourth gear 47b are formed as a worm gear that meshes with the lead screw 3. The output torque of the motor 48b is transmitted and locked via the worm gear connected to the flexible shaft 44b, resulting in better self-locking effect. In particular, as shown in the figure... Figure 9 As shown, the first gearbox is connected above the upper rail 1, the second gearbox is placed below the upper rail 1, and the motor 48b is horizontally mounted on the outside of the upper rail 1 and the lower rail 2, giving more space to the upper rail 1 for the components.

[0053] like Figure 10 As shown, the difference between the center console assembly of the fourth preferred embodiment of this utility model and the first preferred embodiment lies only in the drive mechanism 4c. Figure 11 As shown, the drive mechanism 4c includes a housing 41c, a first gear 42c, a second gear 43c, a flexible shaft 44c, and a motor 45c. The housing 41c is bolted to the lower part of the upper rail 1. The first gear 42c and the second gear 43c are rotatably mounted on the housing 41c to form a gearbox. The motor 45c is bolted to the upper part of the upper rail 1 and connected to the gearbox via the flexible shaft 44c. The second gear 43c has an internal thread that meshes with the lead screw 3. Thus, the motor 45c drives the gearbox via the flexible shaft 44c, and the gearbox meshes with the lead screw 3 to achieve transmission. In this embodiment, the first gear 42c and the second gear 43c mesh to form a worm gear that meshes with the lead screw 3. The output torque of the motor 45c is transmitted and locked via the flexible shaft 44c connected to the worm gear. Compared to the third embodiment, this reduces the number of reversing gearboxes by one stage, resulting in lower cost and better self-locking performance. Specifically, as... Figure 12 As shown, motor 45c is vertically mounted on the outside of upper rail 1 and lower rail 2.

[0054] like Figure 13 As shown, the center console assembly according to the fifth preferred embodiment of this utility model includes an upper rail 1, a lower rail 2, a rack 3a, and a drive mechanism 4d. The upper rail 1 is movably mounted on the lower rail 2, and the rack 3a is fixedly connected to the lower rail 2 by front and rear mounting bolts. Figure 14 As shown, the drive mechanism 4d includes a housing 41d, a first gear 42d, a second gear 43d, a third gear 44d, and a motor 45d. The housing 41d is bolted to the lower part of the upper rail 1. The first gear 42d, second gear 43d, and third gear 44d are rotatably mounted on the housing 41d to form a gearbox. The motor 45d is bolted to the gearbox. The output shaft of the motor 45d is connected to the first gear 42d. The third gear 44d is connected to the first gear 42d via the second gear 43d and has an external thread that meshes with the rack 3a. Specifically, as shown... Figure 14 As shown, the second gear 42d and the third gear 43d are both coaxial gears consisting of two gears arranged coaxially. The input gear of the second gear 43d meshes with the first gear 42d for transmission, and the output gear of the second gear 43d meshes with the input gear of the third gear 44d for transmission. The output gear of the third gear 44d has an external thread that meshes with the rack 3a for transmission, thereby driving the gearbox through the motor 45d, and then achieving transmission through the meshing of the gearbox with the rack 3a. In this embodiment, the output torque of the motor 45d is reduced and increased through two stages of gear reduction, allowing the motor 45d to be made smaller and more compact, which is beneficial for saving space. In particular, as Figure 15 As shown, the motor 45d is mounted parallel to the rack 3a and connected to the inner side of the upper rail 1 and the lower rail 2 along with the gearbox, which can reduce noise transmission and provide more space for the upper hand parts.

[0055] like Figure 16 As shown, the difference between the center console assembly of the sixth preferred embodiment and the fifth preferred embodiment lies only in the drive mechanism 4b. The specific structure of the drive mechanism 4b can be found in the third preferred embodiment, such as... Figure 8 As shown, the only difference is that the fourth gear 47b is replaced with... Figure 14 The coaxial gear shown is a third gear 44d, which consists of two gears arranged coaxially, and meshes with the rack 3a through the external thread of the output gear (see reference). Figure 17 Specifically, the first gearbox is connected above the upper rail 1, the second gearbox is placed below the upper rail 1, and the motor 48b is horizontally mounted on the outside of the upper rail 1 and the lower rail 2, giving more space to the upper rail 1 for the components, such as... Figure 17 As shown.

[0056] like Figure 18 As shown, the difference between the center console assembly of the seventh preferred embodiment of this utility model and the fifth preferred embodiment lies only in the drive mechanism 4c. The specific structure of the drive mechanism 4c can be found in the fourth preferred embodiment, such as... Figure 11 As shown, the only difference is that the second gear 43c is replaced with... Figure 14 The third gear 44d shown is a coaxial gear that meshes with the rack 3a via the external thread of the output gear, similar to the third gear 44d which is coaxially arranged with the two gears. Specifically, the motor 45c is vertically mounted outside the upper rail 1 and the lower rail 2, as shown... Figure 19 As shown.

[0057] like Figure 20 As shown, the difference between the center console assembly of the eighth preferred embodiment of this utility model and the first preferred embodiment is that it also includes a trim cover 5, which is composed of four soft trim strips 51, combined with... Figure 21 Each soft trim strip 51 is respectively attached to the top of the lower rail 2 on both sides of the two legs 11 of the upper rail 1 for decoration and protection, thereby improving aesthetics, protection, and functionality. The surface of the lower rail 2 is treated with hard anodizing to improve wear resistance and corrosion resistance. At the joint between the upper rail 1 and the lower rail 2, a cover 5 is attached to the lower rail 2 to cover its surface. The structure is simple and easy to install. The cover 5 provides a good appearance while also having shock absorption and noise reduction functions.

[0058] like Figure 22 As shown, the difference between the center console assembly of the ninth preferred embodiment of this utility model and the eighth preferred embodiment lies only in the trim cover 5a, which consists of three hard trim strips 51a, combined with... Figure 23Each rigid trim strip 51a is formed by a co-extrusion process of a plastic strip 511 and at least one rubber strip 512. Figure 24 Each rigid trim strip 51a is respectively attached to the top of the lower rail 2 on both sides of the two legs 11 of the upper rail 1 for decoration and protection, thereby improving aesthetics, protection, and functionality. The adhesive strip 512 of each rigid trim strip 51a is provided adjacent to the legs 11 to enhance sealing or provide additional cushioning. The surface of the lower rail 2 is treated with ordinary anodizing or without additional surface treatment. At the mating point of the upper rail 1 and the lower rail 2, the cover 5a is attached to the lower rail 2 to form an integral cover, providing stronger structural strength and durability, and reducing overall cost.

[0059] like Figure 25 As shown, the difference between the center console assembly of the tenth preferred embodiment of this utility model and the first preferred embodiment is that it further includes a sliding assembly 6, which includes four retainer assemblies 61, which are respectively disposed between the upper rail 1 and the lower rail 2 to provide rolling contact, reduce friction, realize smooth sliding between the upper rail 1 and the lower rail 2, and reduce wear and friction caused by direct contact. Figure 26 and Figure 27 As shown, three balls 612 are held together by a retainer 611 to form a retainer assembly 61. In this embodiment, the retainer 611 is a plastic retainer. The four retainer assemblies 61 are respectively snapped into the upper rail 1 in the left-right and front-back directions and cooperate with the lower rail 2. It has the characteristics of low cost and simple structure, convenient installation process, stable structure, and can ensure stable sliding between the upper rail 1 and the lower rail 2.

[0060] like Figure 28 As shown, the difference between the center console assembly of the eleventh preferred embodiment and the tenth preferred embodiment lies only in the sliding assembly 6a, which includes four roller assemblies 61a, respectively disposed between the upper rail 1 and the lower rail 2 to provide rolling contact, reduce friction, and achieve smooth sliding between the upper rail 1 and the lower rail 2, thereby reducing wear and friction caused by direct contact. Figure 29 As shown, the roller assembly 61a includes a compression member 611a, a rotating frame 612a, a first roller 613a, and a second roller 614a, which are combined with... Figure 30 The rotating frame 612a is connected to the upper rail 1 via a compression member 611a to form a lever structure. The first roller 613a is mounted on the rotating frame 612a and floats up and down with the upper rail 1 via the lever structure, while maintaining contact with the upper rail 1, forming an upper roller mechanism. The second roller 614a is fixed to the upper rail 1 by a pin and simultaneously contacts the lower rail 2. The two layers of rollers (i.e., the first roller 613a and the second roller 614a) together support the upper rail 1, as shown below. Figure 31As shown. It should be understood that the compression component 611a here provides tension between the upper rail 1 and the lower rail 2, which can prevent abnormal noise on bumpy roads. The four roller assemblies 61a are installed on the upper rail 1 in the left-right and front-back directions and cooperate with the lower rail 2. The friction is small, the noise is low, and the sliding speed is fast, allowing the upper rail 1 to slide quickly, improving the response speed and efficiency.

[0061] like Figure 32 As shown, the difference between the center console assembly of the twelfth preferred embodiment of this utility model and the fifth preferred embodiment is that it further includes a buffer assembly 7. The gearbox is mounted on the upper rail 1 via the buffer assembly 7, which is a device to improve stability. Figure 33 As shown, the buffer assembly 7 includes a stepped bolt 71 and a buffer member 72. The gearbox housing 41e has a mounting hole 42e. The stepped bolt 71 passes through a mating hole (not shown) in the upper rail 1 and is inserted into the mounting hole 42e of the housing 41e for installation. The buffer member 72, located in the mating hole of the upper rail 1, is fitted onto the stepped bolt 71 for installation. In this embodiment, the buffer member 72 is a rubber component. Additionally, the housing 41e has a circular boss 43e, which inserts into the oblong hole 13 of the upper rail 1 (see...). Figure 34 The internal fit provides protection and support. Specifically, during the fit and operation of the gearbox and its counterpart (such as the lead screw 3 or rack 3a), there are floating tolerances in the vertical (Y-axis) and horizontal (Z-axis) directions. To ensure smooth fit between the gearbox and its counterpart during installation and operation, the buffer assembly 7 is used to eliminate these tolerances. The upper rail 1 and the gearbox are fitted by stepped bolts 71. The design of placing the buffer 72 in the mating hole of the upper rail 1 allows the gearbox to translate in three directions (X, Y, and Z axes). At the same time, the housing 41 is limited in the corresponding position of the oblong hole 13 in the upper rail 1 to restrict the floating of the gearbox in the travel direction (X-axis). Through the fit of the buffer 72 and the oblong hole 13, the gearbox can float in the vertical (Y-axis) and horizontal (Z-axis) directions. This method is low-cost, simple in structure, easy to install, and provides stable performance, ensuring precise fit between the gearbox and its counterpart during operation, reducing errors, and improving reliability and performance.

Various variations can be made to the above embodiments of this utility model. That is, all simple and equivalent changes and modifications made based on the claims and description of this utility model application fall within the protection scope of the claims of this utility model patent. Any aspects of this utility model not described in detail are conventional technical content.
