Description

[0002] Car seats are an indispensable basis for drivers and passengers to ride, and their importance is self-evident. In view of the diversity of heights and body shapes of drivers and passengers, car seats generally have the function of front and rear adjustment to ensure that every passenger can enjoy the best riding experience and comfort.

[0003] As car consumers' requirements for comfort continue to increase, electric seat adjustment has become the first choice for many consumers. In the research and development of car seats, the assembly design of the electric left and right slide rails and motors is crucial, which is directly related to the reliability of the product, the convenience of installation and the final driving experience.

[0028] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0029] Please refer to Figures 1 to 7 For achieving the above object, the present utility model provides the following technical solutions:

[0030] An automobile seat slide rail assembly includes a seat frame 1, and a left rail 2 and a right rail 3 are provided below the seat frame 1; the left rail 2 and the right rail 3 have the same structure and are symmetrically arranged, and a cross beam 4 is provided between the left rail 2 and the right rail 3; the left rail 2 includes a first fixed guide rail 201, and the cross section of the first fixed guide rail 201 is in an "L" shape; a first movable slide rail 202 is provided in the first fixed guide rail 201, and the first movable slide rail 202 is slidably connected to the first fixed guide rail 201, and the cross section of the first movable slide rail 202 is in a "Ji" shape; the right rail 3 includes a second fixed guide rail 301, and the cross section of the second fixed guide rail 301 is in an "L" shape; a second movable slide rail 302 is provided in the second fixed guide rail 301, and the second movable slide rail 302 is slidably connected to the second fixed guide rail 301, and the cross section of the second movable slide rail 302 is in a "Ji" shape; one end of the cross beam 4 is arranged above the first movable slide rail 202, and the first movable slide rail 202 is fixedly connected to the cross beam 4 by bolts; the other end of the cross beam 4 is arranged above the second movable slide rail 302, and the second movable slide rail 302 is fixedly connected to the cross beam 4 by bolts; a first lead screw 203 is provided on the bottom wall of the first fixed guide rail 201, and a first reducer 204 is slidably connected to the outer wall of the first lead screw 203; a second lead screw 303 is provided on the bottom wall of the second fixed guide rail 301, and a second reducer 304 is slidably connected to the outer wall of the second lead screw 303; a double-shaft drive motor 5 is installed above the cross beam 4, and a first output shaft 6 of the double-shaft drive motor 5 penetrates through the side wall of the first movable slide rail 202 and is fixedly connected to the input end of the first reducer 204, and a second output shaft 7 of the double-shaft drive motor 5 penetrates through the side wall of the second movable slide rail 302 and is fixedly connected to the input end of the second reducer 304.

[0031] The seat frame 1 serves as the basic support structure of the entire seat. The seat frame 1 is responsible for bearing the weight of the seat and its accessories and providing a stable installation platform for them. The left track 2 and the right track 3 have the same structure and are symmetrically arranged. They are respectively located on the left and right sides of the seat frame 1. The left track 2 includes a first fixed guide rail 201 and a first movable slide rail 202, and the right track 3 includes a second fixed guide rail 301 and a second movable slide rail 302. The cross-sections of the first fixed guide rail 201 and the second fixed track are in an "L" shape, providing sliding tracks for the first movable slide rail 202 and the second movable slide rail 302 respectively. The cross-sections of the first movable slide rail 202 and the second movable slide rail 302 are in a "Ji" shape. This design not only increases the contact area of the seat slide rails, improves the load-bearing capacity of the seat slide rails, but also makes the sliding between the seat slide rails smoother. The crossbeam 4 is connected between the left track 2 and the right track 3. One end of the crossbeam 4 is arranged above the first movable slide rail 202 and is fixedly connected to the first movable slide rail 202 by bolts. The other end of the crossbeam 4 is arranged above the second movable slide rail 302 and is fixedly connected to the second movable slide rail 302 by bolts. The crossbeam 4 not only strengthens the connection between the left track 2 and the right track 3, but also provides a platform for installing the double-shaft drive motor 5.

[0032] A first lead screw 203 is provided on the bottom wall of the first fixed guide rail 201, and a first reducer 204 is slidably connected to the outer wall of the first lead screw 203. A second lead screw 303 is provided on the bottom wall of the second fixed guide rail 301, and a second reducer 304 is slidably connected to the outer wall of the second lead screw 303. The combined use of the first lead screw 203 and the first reducer 204, and the second lead screw 303 and the second reducer 304 realizes the conversion of the rotational motion of the double-shaft drive motor 5 into the linear motion of the seat slide rails. When the double-shaft drive motor 5 is started, it will drive the first reducer 204 and the second reducer 304 to rotate through the output shaft, and then drive the first lead screw 203 and the second lead screw 303 to slide in the first fixed guide rail 201 and the second fixed guide rail 301 respectively, thereby pushing the first movable slide rail 202 and the second movable slide rail 302 to move.

[0033] A double-shaft drive motor 5 is installed above the crossbeam 4. The double-shaft drive motor 5 is the power source of the entire slide rail assembly. The first output shaft 6 of the double-shaft drive motor 5 penetrates the side wall of the first movable slide rail 202 and is fixedly connected to the input end of the first reducer 204. The second output shaft 7 penetrates the side wall of the second movable slide rail 302 and is fixedly connected to the input end of the second reducer 304. In this way, the double-shaft drive motor 5 can drive the movable slide rails of the left track 2 and the right track 3 to move simultaneously, realizing the front-back adjustment function of the seat.

[0034] Please refer to Figure 4 、 Figure 5, as an embodiment of the present utility model, the two side walls of the first fixed guide rail 201 are respectively bent inward to form the first limiting sliding grooves 8, and the height of the outer side wall of the first fixed guide rail 201 is greater than that of its inner side wall; the lower ends of the two side walls of the first movable sliding rail 202 are respectively bent upward to form the second limiting sliding grooves 9, wherein the first limiting sliding grooves 8 and the second limiting sliding grooves 9 are engaged with each other and slidably connected (in this embodiment, since the structures of the left rail and the right rail are the same, the structures of the second fixed guide rail and the second movable sliding rail will not be described repeatedly).

[0035] In the above solution, the first fixed guide rail 201 serves as the static part in the left rail 2. The two side walls of the first fixed guide rail 201 are designed to be bent inward to form two parallel first limiting sliding grooves 8. The first limiting sliding grooves 8 not only provide a sliding track for the first movable sliding rail 202, but also limit the moving range of the first movable sliding rail 202 through its specific shape and size, ensuring the stability and accuracy of the left rail 2; in addition, the height of the outer side wall of the first fixed guide rail 201 is designed to be greater than that of its inner side wall. This design helps to increase the structural strength of the left rail 2 and prevent external objects from accidentally entering the inside of the sliding rail; the first movable sliding rail 202 serves as the dynamic part in the left rail 2. The lower ends of the two side walls of the first movable sliding rail 202 are respectively bent upward to form two second limiting sliding grooves 9 that match the first limiting sliding grooves 8; the second limiting sliding grooves 9 are designed to be able to tightly engage within the first limiting sliding grooves 8 and slide smoothly therein; through this design, the first movable sliding rail 202 can perform stable linear motion under the guidance of the first fixed guide rail 201, while avoiding the possible shaking or deviation from the track during the sliding process.

[0036] When the first movable sliding rail 202 moves under the action of an external driving force, the second limiting sliding grooves 9 thereon will tightly slide along the first limiting sliding grooves 8 on the first fixed guide rail 201. This sliding connection not only ensures that the first movable sliding rail 202 can move along a predetermined path, but also provides additional stability and support force through the engagement between the first limiting sliding grooves 8 and the second limiting sliding grooves 9; the engagement between the first limiting sliding grooves 8 and the second limiting sliding grooves 9 not only limits the moving range of the first movable sliding rail 202 to prevent it from exceeding the predetermined sliding area, but also precisely guides the moving direction of the first movable sliding rail 202 through the shape and size of the first limiting sliding grooves 8 and the second limiting sliding grooves 9. This limiting and guiding function ensures that the left rail 2 can maintain a smooth and accurate movement trajectory when adjusting the seat position.

[0037] Please refer to Figures 2 to 5, as an embodiment of the present utility model, first right-angled connecting plates 205 are respectively provided at both ends of the first speed reducer 204. The horizontal top edge of the first right-angled connecting plate 205 abuts against the top wall of the first movable slide rail 202; a first threaded hole 10 is provided on the horizontal top edge of the first right-angled connecting plate 205, and a first through hole 11 adapted to the first threaded hole 10 is provided on the top wall of the first movable slide rail 202; second right-angled connecting plates 305 are respectively provided at both ends of the second speed reducer 304. The horizontal top edge of the second right-angled connecting plate 305 abuts against the top wall of the second movable slide rail 302; a second threaded hole 12 is provided on the horizontal top edge of the second right-angled connecting plate 305, and a second through hole 13 adapted to the second threaded hole 12 is provided on the top wall of the second movable slide rail 302.

[0038] In the above-mentioned solution, first right-angled connecting plates 205 are respectively provided at both ends of the first speed reducer 204. The first connecting plate extends in a right-angled form, and its horizontal top edge directly abuts against the top wall of the first movable slide rail 202; this design ensures a stable connection between the first speed reducer 204 and the first movable slide rail 202 and provides the necessary support; a first threaded hole 10 is designed on the horizontal top edge of the first right-angled connecting plate 205, and the first threaded hole 10 is accurately positioned and opened so as to be adapted to the first through hole 11 pre-opened on the top wall of the first movable slide rail 202. This design allows the use of bolts or other fasteners to firmly fix the first speed reducer 204 on the first movable slide rail 202; similar to the first speed reducer 204, second right-angled connecting plates 305 are also provided at both ends of the second speed reducer 304. The second connecting plate also extends in a right-angled form and abuts against the top wall of the second movable slide rail 302. This design ensures a stable connection between the second speed reducer 304 and the second movable slide rail 302; a second threaded hole 12 is also designed on the horizontal top edge of the second right-angled connecting plate 305, and the second threaded hole 12 is adapted to the second through hole 13 pre-opened on the top wall of the second movable slide rail 302, allowing the use of bolts or other fasteners to firmly fix the second speed reducer 304 on the second movable slide rail 302; the design of the first right-angled connecting plate 205 ensures a stable connection between the first speed reducer 204 and the first movable slide rail 202; at the same time, the design of the second right-angled connecting plate 305 ensures a stable connection between the second speed reducer 304 and the second movable slide rail 302, and also provides the necessary mechanical support and power transmission function; this design enables the slide rail assembly to efficiently adjust the position of the seat while ensuring the stability of the structure and the characteristics of easy installation and maintenance.

[0039] Please refer to Figures 4 to 7, as an embodiment of the present utility model, a mounting hole 14 is provided at one end of the cross beam 4 close to the first movable slide rail 202. A first fixing bolt 15 is provided in the mounting hole 14, and the first fixing bolt 15 passes through the first through hole 11 and is fixedly connected to the first threaded hole 10; a waist-shaped hole 16 is provided at one end of the cross beam 4 close to the second movable slide rail 302. A second fixing bolt 17 is provided in the waist-shaped hole 16, and the second fixing bolt 17 passes through the second through hole 13 and is fixedly connected to the second threaded hole 12.

[0040] In the above-mentioned solution, the cross beam 4 is a key component connecting the left rail 2 and the right rail 3. The cross beam 4 is designed to have sufficient strength and stiffness; both ends of the cross beam 4 are respectively close to the first movable slide rail 202 and the second movable slide rail 302, and a specific connection structure is designed to fixedly connect with the first movable slide rail 202 and the second movable slide rail 302; at one end of the cross beam 4 close to the first movable slide rail 202, a circular mounting hole 14 is provided, and the mounting hole 14 is accurately positioned and provided to be adapted to the first through hole 11 on the first movable slide rail 202 and the first threaded hole 10 on the first right-angle connecting plate 205; at one end of the cross beam 4 close to the second movable slide rail 302, a long strip-shaped waist-shaped hole 16 is provided, and the design of the waist-shaped hole 16 allows a certain degree of adjustment of the position of the second movable slide rail 302 to adapt to different installation requirements or manufacturing tolerances; the first fixing bolt 15 and the second fixing bolt 17 are designed to have diameters and lengths adapted to the mounting hole 14 and the waist-shaped hole 16, so as to be able to pass through the through holes and be screwed into the corresponding first threaded hole 10 and second threaded hole 12, thereby firmly connecting the cross beam 4 to the first movable slide rail 202 and the second movable slide rail 302 respectively.

[0041] Please refer to Figure 7 , as an embodiment of the present utility model, the cross beam 4 has a "Z" - shaped structure. One end of the cross beam 4 is bent downward to form a motor mounting portion 401; a double - shaft drive motor 5 is provided above the motor mounting portion 401. A weight - reducing through - slot 18 is provided at the bottom of the motor mounting portion 401; the other end of the cross beam 4 is bent upward to form a support portion 402. A support guiding groove 19 is provided in the middle of the support portion 402 along its length direction; the second output shaft 7 of the double - shaft drive motor 5 is arranged in the support guiding groove 19, and positioning clamping sleeves 20 adapted to the second output shaft 7 are provided on both sides of the support guiding groove 19.

[0042] In the above-described solution, the cross beam 4 is designed as a "Z" - shaped structure. This design not only enhances its structural strength but also provides a suitable space for the installation and support of the dual - axis drive motor 5. One end of the cross beam 4 is bent downward to form a motor installation part 401. The motor installation part 401 is located at one end of the cross beam 4 and is bent downward to provide sufficient space for installing the dual - axis drive motor 5. This design enables the dual - axis drive motor 5 to be firmly fixed on the cross beam 4 while avoiding interference with other components. By opening a weight - reducing through - slot 18 at the bottom of the motor installation part 401, the weight - reducing through - slot 18 not only reduces the weight of the cross beam 4, lowers the cost of the overall structure, but also helps improve the heat dissipation performance of the cross beam 4 and extends the service life of the dual - axis drive motor 5. The other end of the cross beam 4 is bent upward to form a support part 402, which is used to support and guide the second output shaft 7 of the dual - axis drive motor 5. The second output shaft 7 of the dual - axis drive motor 5 is arranged in the support and guide groove 19, which is used to achieve specific motions or functions. This design ensures the stability and accuracy of the second output shaft 7 during the movement process. In the middle of the support part 402, a support and guide groove 19 is opened along its length direction. The support and guide groove 19 is designed to be adapted to the second output shaft 7 to provide precise guidance and support. The presence of the support and guide groove 19 helps reduce the friction and wear of the second output shaft 7 during the movement process and improves its service life. On both sides of the support and guide groove 19, positioning clamping sleeves 20 adapted to the second output shaft 7 are provided. The positioning clamping sleeves 20 are designed to closely wrap around the second output shaft 7 to ensure its stability and accuracy during the movement process. The positioning clamping sleeves 20 also play a role in preventing the second output shaft 7 from deviating from the track during the movement process, thereby improving the reliability and safety of the entire system.

[0043] Please refer to Figure 7 , as an embodiment of the present utility model, a rubber shock - absorbing block 21 is provided on one side of the motor installation part 401 close to the first output shaft 6 of the dual - axis drive motor 5. On one side of the motor installation part 401 close to the second output shaft 7 of the dual - axis drive motor 5, an elastic extrusion plate 22 is vertically provided. One end of the dual - axis drive motor 5 is connected to the rubber shock - absorbing block 21 through a connecting piece, and the other end of the dual - axis drive motor 5 abuts against the elastic extrusion plate 22.

[0044] In the above-described solution, the motor mounting portion 401 is a part of the cross beam 4 specifically designed for mounting the dual-axis drive motor 5. To further enhance the stability of the system and reduce vibration, two key shock-absorbing and fixing components, namely the rubber shock-absorbing block 21 and the elastic pressing plate 22, are configured on the motor mounting portion 401. The rubber shock-absorbing block 21 is installed on one side of the motor mounting portion 401 close to the first output shaft 6 of the dual-axis drive motor 5. Its main function is to absorb and reduce the vibration and noise generated during the operation of the dual-axis drive motor 5, thereby protecting the dual-axis drive motor 5 and surrounding components from damage. One end of the dual-axis drive motor 5 is tightly connected to the rubber shock-absorbing block 21 through a connecting member. This connection method ensures that the dual-axis drive motor 5 can effectively absorb and disperse energy through the rubber shock-absorbing block 21 during vibration, thereby reducing the impact on the overall system. The elastic pressing plate 22 is vertically arranged on one side of the motor mounting portion 401 close to the second output shaft 7 of the dual-axis drive motor 5. The elastic pressing plate 22 not only provides additional support for the dual-axis drive motor 5 but also further reduces the vibration and sway of the dual-axis drive motor 5 during operation through its elastic characteristics. The other end of the dual-axis drive motor 5 is directly abutted against the elastic pressing plate 22. This abutting method enables the dual-axis drive motor 5 to absorb and disperse vibration energy through the elastic deformation of the elastic pressing plate 22 when subjected to vibration, thereby improving the stability and reliability of the system.

[0045] When the dual-axis drive motor 5 starts, it generates certain vibration and noise. These vibration and noise are first transmitted to the rubber shock-absorbing block 21 through the connecting member. The rubber shock-absorbing block 21 utilizes its good elasticity and damping characteristics to absorb and disperse most of the vibration energy, thereby reducing the impact of the dual-axis drive motor 5 on the overall system. At the same time, the other end of the dual-axis drive motor 5 is abutted against the elastic pressing plate 22, further enhancing the stability of the dual-axis drive motor 5 and reducing vibration. During the operation of the dual-axis drive motor 5, the rubber shock-absorbing block 21 and the elastic pressing plate 22 work together to provide a stable and shock-absorbing mounting environment for the dual-axis drive motor 5. This design not only improves the operating efficiency and reliability of the dual-axis drive motor 5 but also extends the service life of the dual-axis drive motor 5 and reduces the overall noise and vibration level of the system.

[0046] Please refer to Figure 7 , as an embodiment of the present invention, the lower end of the elastic pressing plate 22 is fixedly connected to the cross beam 4. An avoidance groove 23 adapted to the second output shaft 7 is provided above the elastic pressing plate 22, and the avoidance groove 23 and the support guiding groove 19 are located at the same horizontal height.
