[0027] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0028] Reference below Figure 1-Figure 4 A slide rail mechanism 100 according to an embodiment of the present invention is described.

[0029] like Figure 1-Figure 4 As shown, the slide rail mechanism 100 according to an embodiment of the present invention includes: a moving device 10 , a screw rod 20 and a supporting device 30 .

[0030] The moving device 10 cooperates with the screw rod 20 and can move along the axial direction of the screw rod 20; along the axial direction of the screw rod 20, support devices 30 are provided on both sides of the moving device 10, and the support device 30 is sleeved on the screw rod 20 to support the screw rod 20. The support device 30 cooperates with the moving device 10, and when the moving device 10 moves, it can drive the support device 30 to move along the moving direction of the moving device 10.

[0031] It should be noted that the slide rail mechanism 100 of the present application can be applied to, but is not limited to, vehicle seats, etc. The present application uses the application of the slide rail mechanism 100 to a vehicle seat as an example for description.

[0032] The moving device 10 cooperates with the screw rod 20 and can move along the axial direction of the screw rod 20 (ie Figure 1As some embodiments of the present application, the mobile device 10 includes a gear box, and the mobile device 10 and the screw 20 are matched through the gear box. The gear box may include a multi-stage worm gear mechanism. The mobile device 10 can move along the axial direction of the screw 20 (i.e. Figure 1 The vehicle seat is moved in the X direction as shown in the figure to adjust the position of the vehicle seat.

[0033] Along the axial direction of the screw rod 20 (ie Figure 1 In other words, along the moving direction of the mobile device 10, both sides of the mobile device 10 are provided with support devices 30, and the support devices 30 are sleeved on the screw rod 20 to support the screw rod 20. As some embodiments of the present application, along the axial direction of the screw rod 20 (i.e. Figure 1 The two supporting devices 30 are arranged on both sides of the mobile device 10, and the two supporting devices 30 are both sleeved on the screw rod 20 to support the screw rod 20. Specifically, the supporting devices 30 have a matching hole 315 that matches the screw rod 20, and the screw rod 20 can pass through the matching holes 315 of the two supporting devices 30 to be supported.

[0034] The supporting device 30 cooperates with the mobile device 10, and when the mobile device 10 moves, the supporting device 30 can be driven to move along the moving direction of the mobile device 10 (i.e. Figure 1 Specifically, the two supporting devices 30 move along the moving direction of the moving device 10 (ie, the X direction shown in FIG. Figure 1 The two supporting devices 30 are arranged on both sides of the mobile device 10. When the mobile device 10 moves on the screw rod 20, the mobile device 10 can drive the two supporting devices 30 to move along the moving direction of the mobile device 10 (ie Figure 1 In other words, the moving direction of the two supporting devices 30 is the same as the moving direction of the moving device 10.

[0035] As some embodiments of the present application, when the mobile device 10 moves, it can push the support device 30 located in the front along the moving direction of the mobile device 10 (ie Figure 1 The supporting device 30 at the rear can be pulled to move along the moving direction of the moving device 10 (ie the X direction shown in FIG. Figure 1 The X direction shown in FIG.

[0036] It should be noted that, when the mobile device 10 moves, the supporting device 30 can be driven to move along the moving direction of the mobile device 10 (ie Figure 1The support device 30 can move in the X direction as shown, so that the support device 30 can continuously support the part of the screw rod 20 near the position of the mobile device 10 during the movement of the mobile device 10, so that the support device 30 plays a role of auxiliary support, significantly improving the force condition of the screw rod 20, reducing the deformation amplitude of the screw rod 20 or even preventing the screw rod 20 from deforming, thereby making the cooperation between the mobile device 10 and the screw rod 20 precise and making the sliding of the mobile device 10 stable and smooth.

[0037] Therefore, by providing support devices 30 on both sides of the moving device 10 to support the screw rod 20, and enabling the supporting devices 30 to be driven to move along the moving direction of the moving device 10 when the moving device 10 moves, the screw rod 20 can be reliably supported, the stress condition of the screw rod 20 can be significantly improved, and the risk of deformation of the screw rod 20 can be reduced, thereby enabling the moving device 10 to slide steadily and smoothly, which is beneficial to improving the reliability of the slide rail mechanism 100.

[0038] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the supporting device 30 includes: a shell 31, a connecting member 33, and a winding member 34. The shell 31 defines a accommodating space 311 and is sleeved on the screw rod 20. The winding member 34 is accommodated in the accommodating space 311 and cooperates with the shell 31. The two ends of the connecting member 33 are respectively connected to the winding member 34 and the moving device 10. The winding member 34 can retract the connecting member 33 into the accommodating space 311.

[0039] In which, the shell 31 defines a accommodating space 311. As some embodiments of the present application, the shell 31 includes an upper shell 312 and a lower shell 313. The upper shell 312 and the lower shell 313 are connected and define the accommodating space 311. The upper shell 312 has a mating hole 315 that cooperates with the screw rod 20. The screw rod 20 can pass through the mating hole 315 of the upper shell 312 of the support device 30 to be supported.

[0040] The reel 34 is housed in the accommodating space 311. Specifically, the entire structure of the reel 34 is housed in the accommodating space 311. The reel 34 can be configured as, but not limited to, a coil spring or a torsion spring. In some embodiments of the present application, the reel 34 is configured as a take-up torsion spring. The reel 34 cooperates with the housing 31. For example, the reel 34 is fixedly connected to the housing 31, or the housing 31 has a protrusion 36 formed therein, the protrusion 36 being located in the accommodating space 311, and the center hole of the reel 34 is sleeved over the protrusion 36.

[0041] The two ends of the connector 33 are connected to the reel 34 and the mobile device 10, respectively. That is, the connector 33 has two opposite ends, one end of which is connected to the reel 34, and the other end is connected to the mobile device 10. The connection method between the connector 33 and the reel 34 can be, but is not limited to, welding, snap-on, etc., and the connection method between the connector 33 and the mobile device 10 can be, but is not limited to, welding, snap-on, etc. In some embodiments of the present application, the connector 33 is connected to the reel 34 and the mobile device 10 by welding. The connector 33 can be constructed as, but is not limited to, a traction wire, a hard guide wire, etc. In some embodiments of the present application, the connector 33 is constructed as a traction wire. The reel 34 can reel the connector 33 into the accommodating space 311 so that part of the connector 33 is accommodated in the accommodating space 311 of the shell 31.

[0042] As some embodiments of the present application, when the mobile device 10 moves, it can push the upper shell 312 of the support device 30 located in the front to push the support device 30 located in the front along the moving direction of the mobile device 10 (i.e. Figure 1 The supporting device 30 at the rear can be moved in the X direction (shown in FIG. 1 ), and the corresponding reeling member 34 can be pulled by the rear connecting member 33 to pull the supporting device 30 at the rear along the moving direction of the moving device 10 (ie Figure 1 The X direction shown in FIG.

[0043] As some embodiments of the present application, the connecting member 33 and the corresponding winding member 34 can be constructed as an integral rolled steel strip.

[0044] By connecting the two ends of the connecting member 33 to the reeling member 34 and the moving device 10 respectively, and enabling the reeling member 34 to reel the connecting member 33 into the accommodating space 311, the supporting device 30 and the moving device 10 can be reliably connected, and the moving device 10 can stably and reliably drive the two supporting devices 30 along the moving direction of the moving device 10 (i.e., Figure 1 The guide rail 100 moves in the X direction as shown to form a dynamic support for the screw rod 20. Moreover, such a configuration has a compact structure and high stability, and can also save space for the slide rail mechanism 100, which is beneficial to improving the reliability and stability of the slide rail mechanism 100.

[0045] In some embodiments of the present invention, Figure 1 As shown, along the moving direction of the mobile device 10 , the mobile device 10 can push the front supporting device 30 to move, and the mobile device 10 can pull the rear supporting device 30 to move.

[0046] In the moving direction of the mobile device 10 , the mobile device 10 can push the front support device 30 to move, and the mobile device 10 can pull the rear support device 30 to move.

[0047] As some embodiments of the present application, along the axial direction of the screw rod 20 (ie Figure 1 When the mobile device 10 needs to be moved forward, the mobile device 10 can push the front support device 30 to move forward, and the mobile device 10 can pull the rear support device 30 to move forward.

[0048] As some embodiments of the present application, along the axial direction of the screw rod 20 (ie Figure 1 When the mobile device 10 needs to be moved backward, the mobile device 10 can push the rear support device 30 to move backward, and the mobile device 10 can pull the front support device 30 to move backward.

[0049] Specifically, when the mobile device 10 moves, it can push the upper shell 312 of the support device 30 located in the front to push the support device 30 located in the front along the moving direction of the mobile device 10 (ie Figure 1 The supporting device 30 at the rear can be moved in the X direction (shown in FIG. 1 ), and the corresponding reeling member 34 can be pulled by the rear connecting member 33 to pull the supporting device 30 at the rear along the moving direction of the moving device 10 (ie Figure 1 The X direction shown in FIG.

[0050] Such an arrangement enables the support devices 30 on both sides to follow the moving device 10 along the moving direction of the moving device 10, thereby continuously supporting the part of the screw rod 20 near the position of the moving device 10, making the sliding of the moving device 10 stable and smooth.

[0051] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the shell 31 has a wire groove wall 32 located in the accommodating space 311, and the wire groove wall 32 is arranged in a spiral shape to define a spiral wire groove 321. The spiral wire groove 321 surrounds the winding member 34, and a portion of the connecting member 33 is wound in the spiral wire groove 321 and connected to the winding member 34.

[0052] Among them, the wire groove wall 32 is located in the accommodating space 311, and the wire groove wall 32 is arranged in a spiral shape in the accommodating space 311. The wire groove wall 32 can define a spiral wire groove 321. That is to say, the spiral wire groove 321 is the space defined by the wire groove wall 32. It can be understood that the spiral wire groove 321 is a part of the accommodating space 311, and the spiral wire groove 321 is arranged in a spiral shape around the winding member 34. Part of the structure of the connecting member 33 is wound in the spiral wire groove 321 and is connected to the winding member 34.

[0053] As some embodiments of the present application, when the moving device 10 moves along the axial direction of the screw rod 20 (ie Figure 1When the mobile device 10 moves forward along the axial direction of the screw rod 20 (i.e., the X direction shown in the figure), the connecting member 33 of the supporting device 30 can be gradually retracted into the accommodating space 311 by the retracting member 34, and when the supporting device 30 located in front of the mobile device 10 contacts the mobile device 10, the supporting device 30 located in front of the mobile device 10 can be pushed forward by the mobile device 10. Figure 1 When the mobile device 10 moves forward in the X direction (shown in the figure), the mobile device 10 can gradually pull the rear connecting member 33 out of the corresponding accommodating space 311. When the pulling amount reaches a preset value, the mobile device 10 can pull the rear connecting member 33 to pull the corresponding retracting member 34 to pull the supporting device 30 at the rear along the moving direction of the mobile device 10 (i.e., Figure 1 The X direction shown in FIG.

[0054] It should be noted that in the process of the mobile device 10 pulling the rear support device 30, when the retracting force of the retracting member 34 of the rear support device 30 is less than the static friction of the support device 30, the rear support device 30 is stationary, the connecting member 33 is pulled out by the mobile device 10, and the exposed length of the connecting member 33 gradually increases. As the connecting member 33 is continuously pulled out, the retracting force continues to increase. When the retracting force of the retracting member 34 of the rear support device 30 is greater than the static friction of the support device 30, the support device 30 is pulled, the exposed length of the connecting member 33 remains unchanged, and the support device 30 moves forward with the mobile device 10.

[0055] As some embodiments of the present application, when the moving device 10 moves along the axial direction of the screw rod 20 (ie Figure 1 When the moving device 10 moves backward (in the X direction shown), the connecting member 33 of the supporting device 30 located behind the moving device 10 can be gradually retracted into the accommodating space 311, and the supporting device 30 located behind the moving device 10 can be pushed backward by the moving device 10, and the supporting device 30 located in front of the moving device 10 will be pulled. It should be noted that in the process of the moving device 10 pulling the supporting device 30 in front, when the retracting force of the retracting member 34 of the front supporting device 30 is less than the static friction of the supporting device 30, the front supporting device 30 is stationary, the connecting member 33 is pulled out by the moving device 10, and the exposed length of the connecting member 33 gradually increases. As the connecting member 33 is continuously pulled out, the retracting force continues to increase. When the retracting force of the retracting member 34 of the front supporting device 30 is greater than the static friction of the supporting device 30, the supporting device 30 is pulled, the exposed length of the connecting member 33 remains unchanged, and the supporting device 30 moves backward with the moving device 10.

[0056] It should be noted that, along the axial direction of the screw rod 20 (ie Figure 1 Movement forward or backward (in the X direction shown) can be understood as movement forward or backward along the length direction of the vehicle.

[0057] By making the spiral wire groove 321 surround the winding member 34 and making part of the connecting member 33 wound in the spiral wire groove 321 and connected to the winding member 34, the connecting member 33 can move smoothly during the winding and releasing process, and the arrangement of the connecting member 33 can be adapted to the winding force of the winding member 34, which is beneficial to reducing the risk of the connecting member 33 being entangled or stuck. In addition, the connecting member 33 is wound in the spiral wire groove 321, which can make full use of the accommodating space 311, which is beneficial to improving the space utilization rate of the slide rail mechanism 100.

[0058] In some embodiments of the present invention, Figure 2 As shown, the housing 31 has a sleeve portion 314 , and the sleeve portion 314 is sleeved on the screw rod 20 .

[0059] Among them, the housing 31 defines a storage space 311, and the housing 31 has a sleeve portion 314, and the sleeve portion 314 is sleeved on the screw rod 20. As some embodiments of the present application, the housing 31 includes an upper housing 312 and a lower housing 313, and the upper housing 312 and the lower housing 313 are connected and define the storage space 311. The upper housing 312 has a sleeve portion 314, and the sleeve portion 314 is located outside the storage space 311. As some embodiments of the present application, the sleeve portion 314 can define a matching hole 315, and the matching hole 315 can match with the screw rod 20. The screw rod 20 can pass through the matching hole 315 of the upper housing 312 of the support device 30 to be supported. As some embodiments of the present application, the sleeve portion 314 can define a support groove, and the support groove is adapted to the shape of the screw rod 20 and supports the screw rod 20.

[0060] Such a setting enables the support device 30 to dynamically support the screw rod 20 along the axial direction of the screw rod 20, and the screw rod 20 can guide the moving direction of the support device 30, which can reduce the probability of the support device 30 moving out of position and enable the support device 30 to stably support the screw rod 20.

[0061] In some embodiments of the present invention, Figure 2 As shown, the supporting device 30 further includes a vibration-damping sleeve 35 . The sleeve portion 314 defines a matching hole 315 . The vibration-damping sleeve 35 is received in the matching hole 315 and sleeved on the screw rod 20 .

[0062] The sleeve portion 314 defines a mating hole 315. In other words, the mating hole 315 is formed in the sleeve portion 314 of the housing 31. The vibration-damping sleeve 35 is received in the mating hole 315 and is sleeved on the screw rod 20. In other words, the vibration-damping sleeve 35 is located between the screw rod 20 and the inner wall of the mating hole 315. The material of the vibration-damping sleeve 35 can be, but is not limited to, rubber, silicone, etc. In some embodiments of the present application, the material of the vibration-damping sleeve 35 is rubber.

[0063] By making the support device 30 also include a vibration-damping sleeve 35, and making the vibration-damping sleeve 35 be accommodated in the matching hole 315 and sleeved on the screw rod 20, the vibration and friction between the screw rod 20 and the support device 30 can be reduced. When the support device 30 moves along the screw rod 20, the vibration-damping sleeve 35 can absorb part of the vibration energy and reduce the noise generated by the relative movement of the support device 30 and the screw rod 20, which is beneficial to improving the smooth operation of the slide rail mechanism 100.

[0064] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the slide rail mechanism 100 further includes: a first rail 40 , the first rail 40 defines a rail cavity 41 , and the screw rod 20 and the support device 30 are both accommodated in the rail cavity 41 .

[0065] The first rail 40 defines a track cavity 41, and the track cavity 41 is along the axis direction of the screw rod 20 (ie Figure 1 The screw rod 20 and the supporting device 30 are both accommodated in the track cavity 41. As some embodiments of the present application, such as Figure 1 As shown, the slide rail mechanism 100 further includes a mounting seat 44, and the number of the mounting seats 44 is two, and the two mounting seats 44 are arranged along the axis direction of the screw rod 20 (ie Figure 1 The mounting bases 44 are respectively arranged at both ends of the screw rod 20 in the X direction as shown, and are used to support the screw rod 20.

[0066] As some embodiments of this application, Figure 1 and Figure 4 As shown, the first rail 40 further defines a plurality of rail sub-cavities 42, and the plurality of rail sub-cavities 42 are all along the axis direction of the screw rod 20 (ie Figure 1 The plurality of rail sub-cavities 42 extend in the width direction (ie, the X direction shown in FIG. 1 ) of the slide rail mechanism 100. Figure 1 The first rail 40 is distributed on both sides of the track cavity 41 in the Y direction as shown. This arrangement can improve the structural strength of the first rail 40 and reduce the weight of the first rail 40.

[0067] As some embodiments of this application, Figure 1 and Figure 4 As shown, the track cavity 41 has a plurality of reinforcing ribs 43, and the plurality of reinforcing ribs 43 are arranged along the axis direction of the screw rod 20 (ie Figure 1 The number of the reinforcing ribs 43 may be, but is not limited to, two or three. In some embodiments of the present application, the number of the reinforcing ribs 43 is two, and both reinforcing ribs 43 extend along the axis direction of the screw rod 20 (i.e., Figure 1 The two reinforcing ribs 43 extend along the width direction of the slide rail mechanism 100 (ie, the X direction shown in FIG. Figure 1Such an arrangement can improve the structural strength and rigidity of the first rail 40 and can keep the movement of the slide rail mechanism 100 stable.

[0068] By accommodating the screw rod 20 and the support device 30 in the track cavity 41, the first rail 40 can protect the screw rod 20 and the support device 30, thereby reducing the contamination of the screw rod 20 and the support device 30 by the external environment, which is beneficial to increasing the service life of the slide rail mechanism 100, and can also reduce the impact of the external environment on the slide rail mechanism 100, which is beneficial to improving the smooth operation of the slide rail mechanism 100.

[0069] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the housing 31 has a guide block 316 , which is in guiding engagement with the side wall of the track cavity 41 .

[0070] The housing 31 has a guide block 316, which is matched with the side wall of the track cavity 41. The number of the guide blocks 316 can be multiple, and the number of the guide blocks 316 can be but not limited to two, three, etc. As some embodiments of the present application, the number of the guide blocks 316 is two, and the two guide blocks 316 are along the width direction of the slide rail mechanism 100 (i.e. Figure 1 The two guide blocks 316 are arranged at intervals and located on both sides of the support device 30, and both guide blocks 316 can cooperate with the side wall guides of the track cavity 41. Specifically, along the width direction of the slide rail mechanism 100 (i.e. Figure 1 The track cavity 41 has two side walls that are opposite and spaced apart, and the two guide blocks 316 can respectively cooperate with the two side walls that are opposite and spaced apart.

[0071] Such a configuration can guide the moving direction of the support device 30 , thereby reducing the risk of the support device 30 moving out of position, and is beneficial to improving the reliability of the slide rail mechanism 100 .

[0072] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the moving device 10 includes: a second rail 11, a driving member 12, and a transmission box. The driving member 12 is connected to the second rail 11 and the transmission box, and the driving member 12 is transmission-connected to the transmission member of the transmission box. The transmission member in the transmission box is sleeved on the screw rod 20 and transmission-connected to the screw rod 20. The driving member 12 can drive the transmission member to move along the axial direction of the screw rod 20 to enable the moving device 10 to move along the axial direction of the screw rod 20.

[0073] Among them, the driving member 12 can be constructed as but not limited to a stepper motor, a servo motor, etc. As some embodiments of the present application, the driving member 12 is constructed as a stepper motor. Such a setting can significantly reduce production costs and improve the accuracy of driving.

[0074] The drive member 12 is connected to the second rail 11. The connection method between the drive member 12 and the second rail 11 can be, but is not limited to, welding, bolting, etc. In some embodiments of the present application, the drive member 12 is connected to the second rail 11 by bolting. The drive member 12 is connected to the transmission box. The connection method between the drive member 12 and the transmission box can be, but is not limited to welding, bolting, etc. In some embodiments of the present application, the drive member 12 is connected to the transmission box by bolting.

[0075] The driving member 12 is connected to the transmission member of the transmission box. The transmission box may have multiple transmission members, which are connected in sequence. The driving member 12 is connected to one of the transmission members. The driving member 12 is connected to one of the transmission members in a manner that may be, but not limited to, a gear pair connection, a coupling connection, etc. The other transmission member is sleeved on the screw rod 20 and is connected to the screw rod 20. The driving member 12 can drive the transmission member sleeved on the screw rod 20 to move axially along the screw rod 20 to enable the moving device 10 to move axially along the screw rod 20. As some embodiments of the present application, the transmission member is constructed as a worm and a turbine, the output shaft of the driving member 12 is connected to the worm, and the worm is engaged with the turbine. Specifically, the outer surface of the turbine can be engaged with the worm, and the inner surface of the turbine has a thread that cooperates with the screw 20 (it can be understood that the turbine is constructed as a nut in a screw-nut structure). The driving member 12 drives the worm to rotate, which can drive the turbine to rotate. The rotation of the turbine can drive the moving device 10 to move as a whole along the axial direction of the screw 20, thereby realizing that the driving member 12 drives the transmission member to make the moving device 10 move along the axial direction of the screw 20.

[0076] Such an arrangement can make the structure of the slide rail mechanism 100 simple and reasonable, and can enable the slide rail mechanism 100 to accurately control the movement of the mobile device 10, which is beneficial to improving the ease of use and control accuracy of the slide rail mechanism 100.

[0077] It is understandable that when the mobile device 10 moves and drives the supporting devices 30 on both sides to move, the supporting device 30 located in the moving direction contacts the mobile device 10, and the supporting device 30 located at the rear maintains a certain distance from the mobile device 10.

[0078] The vehicle according to an embodiment of the present invention includes the slide rail mechanism 100 of the above embodiment. By providing support devices 30 on both sides of the mobile device 10 to support the screw rod 20, and enabling the mobile device 10 to drive the support device 30 to move along the moving direction of the mobile device 10 when moving, the screw rod 20 can be reliably supported, the stress condition of the screw rod 20 can be significantly improved, and the risk of deformation of the screw rod 20 can be reduced, thereby enabling the mobile device 10 to slide steadily and smoothly, which is beneficial to improving the reliability of the slide rail mechanism 100.
