Description

Technical Field

[0001] This application relates to the field of automotive seat accessories technology, and in particular to a seat slide rail assembly, a seat, and a vehicle. Background Technology

[0002] In existing vehicle seat designs, to meet the comfort needs of drivers and passengers, seats typically use sliding rail mechanisms for fore-and-aft adjustment. However, because a sliding clearance needs to be provided for the seat, a large gap is created between the seat and other components in the vehicle, such as the armrest and toolbox. During vehicle operation or when passengers are riding, small items such as mobile phones, keys, and cards can easily fall through this gap and end up under the seat, making them difficult to retrieve. If items fall onto the sliding rails, there is also a possibility that the seat's movement relative to the rails may crush or damage them. Utility Model Content

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0026] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.

[0027] Please also refer to Figure 1 and Figure 2 This application provides a seat 100, which can be a seat in a public place such as a cinema or theater, or a seat in a means of transportation such as a vehicle or airplane. In this embodiment, the seat 100 is applied in a vehicle 200, and the seat 100 can serve as a front seat or a rear seat of the vehicle 200 for passengers to sit in.

[0028] Vehicle 200 may include a vehicle body 201, a functional device 203, and the aforementioned seat 100. The vehicle body 201 has a floor 2012. The functional device 203 and the seat 100 are both disposed within the vehicle body 201, with the functional device 203 mounted on the floor 2012. Vehicle 200 may have multiple seats 100, including front seats and rear seats. The seat 100 is mounted on the floor 2012 and located to one side of the functional device 203, with a drop space 205 formed between the seat 100 and the functional device 203. In this embodiment, the seat 100 can slide relative to the floor 2012 to adjust its position. The drop space 205 ensures that the seat 100 will not rub against the functional device 203 during adjustment, improving the smoothness of seat adjustment.

[0029] Please also refer to Figure 2 and Figure 3 Specifically, the seat 100 may have a front surface 101 facing the steering wheel of the vehicle 200 and side surfaces 103 located on both sides of the front surface 101. The seat 100 is located on one side of the functional device 203, and the side surfaces 103 are spaced apart from the functional device 203 to form the aforementioned drop space 205. This specification does not limit the specific structure of the functional device 203, which may include any of the following structures: a sub-dashboard, an armrest box, a toolbox, or a refrigerator. In this embodiment, the seat 100 serves as the front seat of the vehicle 200, and the functional device 203 may be a sub-dashboard.

[0030] Please also refer to Figure 2 , Figure 3 and Figure 4 The seat 100 may include a seat body 10, a shielding assembly 30, and a seat rail assembly 50. The seat body 10 is connected to the floor 2012 via the seat rail assembly 50. The shielding assembly 30 is disposed on the side of the seat body 10 near the functional device 203, and is used to at least partially shield the fall space 205. The seat rail assembly 50 may include a sliding seat 52, a guide rail 54, and a support portion 501. The sliding seat 52 is connected to the seat body 10. The guide rail 54 is fixedly connected to the floor 2012 of the vehicle 200, and has a guide groove 541. The sliding seat 52 is partially embedded in the guide groove 541. The support portion 501 is disposed in the guide groove 541, and the sliding seat 52 is slidably connected to the support portion 501. The guide groove 541 has a groove bottom surface 542, and the support portion 501 protrudes relative to the groove bottom surface 542. During the movement, the sliding seat 52 moves on the surface of the support 501 away from the bottom surface 542 of the groove.

[0031] In the seat 100, if an object 300 dropped by an occupant falls onto the guide rail 54, the support portion 501 protruding from the bottom surface 542 of the groove will support the dropped object 300. When the position of the seat body 10 is adjusted, the sliding seat 52 slides on the guide rail 54. During the movement, the sliding seat 52 moves on the surface of the support portion 501 away from the bottom surface 542, thereby pushing the dropped object 300 supported by the support portion 501 to slide on the support portion 501. The seat 100 of this embodiment supports the dropped object 300 by the support portion 501, reducing the possibility of the dropped object 300 falling onto the bottom surface 542 of the groove. This ensures that when the seat body 10 is adjusted and the sliding seat 52 slides relative to the guide rail 54, the dropped object 300 will not be squeezed and damaged. It also reduces the risk of the vehicle 200 catching fire if the dropped object 300 is a dangerous item and is squeezed.

[0032] In this application, unless otherwise expressly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] In this embodiment, the seat body 10 may include a seat cushion 12 and a backrest 14 connected to the seat cushion 12. The seat cushion 12 is slidably connected to the floor 2012 via a seat slide rail assembly 50, with a gap between the seat cushion 12 and the floor 2012. The backrest 14 is connected to the side of the seat cushion 12 facing away from the floor 2012. This specification does not limit the specific connection method between the seat cushion 12 and the backrest 14. For example, the backrest 14 may be fixedly connected to the seat cushion 12, with the backrest 14 slightly tilted relative to the seat cushion 12 to allow the occupant to lean against it. Alternatively, the backrest 14 may be rotatably connected to the seat cushion 12. In this embodiment, the seat body 10 may also include an adjustment mechanism for adjusting the angle of the backrest 14 relative to the seat cushion 12. The adjustable angle between the backrest 14 and the seat cushion 12 can meet different customer seating needs and improve the seating experience.

[0034] In this embodiment, the side 103 of the seat 100 is understood as the side of the cushion 12, specifically the surface of the cushion 12 facing the functional device 203. The cushion 12 and the functional device 203 are spaced apart, and the side 103 and the side of the functional device 203 facing the cushion 12 are relatively spaced apart to form a drop space 205.

[0035] A shielding component 30 is disposed between the seat cushion 12 and the functional device 203, and serves to at least partially shield the drop space 205. Please also refer to... Figure 2 , Figure 4 and Figure 5 In this embodiment, a first space 121 is formed between the seat cushion 12 and the functional device 203, and a second space 123 is formed between the seat cushion 12 and the floor 2012. The first space 121 and the second space 123 are connected and together form a drop space 205.

[0036] To prevent occupants' belongings from entering the space between the seat cushion 12 and the floor 2012 through the gap between the functional device 203 and the partition strip 32, the partition assembly 30 may include a partition curtain 34. The partition curtain 34 is connected to the seat cushion 12 and located between the first space 121 and the second space 123. The partition curtain 34 separates the first space 121 and the second space 123. If an item 300 falls, it will only fall into the first space 121 under the protection of the partition curtain 34, preventing it from falling into the second space 123 and affecting the movement of the seat body 10, or preventing damage to the item due to the movement of the seat body 10.

[0037] The curtain 34 is fixedly connected to the side 103. The curtain 34 can contact the floor 2012 to effectively prevent falling objects 300 from entering the second space 123 from the first space 121. In this embodiment, the cushion 12 is mounted on the guide rail 54. The maximum distance between the side of the curtain 34 facing the floor 2012 and the floor 2012 is less than the protrusion height of the guide rail 54 relative to the floor 2012. The curtain 34 may not contact the floor 2012, but can work with the guide rail 54 to jointly shield the second space 123.

[0038] To further reduce the likelihood of dropped items 300 falling into the drop space 205, the shielding assembly 30 may also include a shielding strip 32. The shielding strip 32 is connected to the seat cushion 12 and shields the drop space 205. When an occupant's item falls, it will land on the shielding strip 32 instead of falling into the drop space 205, making it easier for the occupant to retrieve it. The drop space 205 forms a drop opening on the side 103 and the side of the functional device 203 away from the floor 2012. When an occupant is seated, items typically fall into the drop space 205 through this drop opening. The shielding strip 32 can be fixedly connected to a relatively high position on the side 103 and is approximately rectangular. The width of the shielding strip 32 is approximately equal to the distance between the side 103 and the functional device 203, thereby shielding the drop space 205. Here, "the distance between the side 103 and the functional device 203" can be understood as the distance between the side 103 and the functional device 203 at the drop opening.

[0039] This specification does not limit the specific structure of the shielding strip 32. For example, the shielding strip 32 can be a rigid strip made of a hard material, or it can be a strip-shaped filler made of a soft material. As an example, the shielding strip 32 may include a fabric outer shell and filling cotton, with the filling cotton filling the fabric outer shell. The fabric outer shell and filling cotton can be well filled between the functional device 203 and the side 103, shielding the drop space 205, while its soft and deformable properties will not excessively hinder the sliding of the seat body 10 relative to the functional device 203.

[0040] In the description of this application, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "inside", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the purpose of simplifying the description of this application and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] In this embodiment, the seat slide rail assembly 50 is disposed between the seat cushion 12 and the floor 2012. The slide seat 52 can be connected to the bottom of the seat cushion 12 by fasteners such as screws and bolts. The slide seat 52 may include an embedded part that is embedded in the guide rail 54 and a connecting part located above the guide rail 54. The connecting part of the slide seat 52 is used for fixed connection with the seat cushion 12, and the embedded part is used for sliding engagement with the guide rail 54. The guide rail 54 is connected to the floor 2012, for example, it can also be connected to the floor 2012 by fasteners such as screws and bolts. The guide rail 54 can be extended along the length direction of the vehicle 200, and the guide groove 541 extends through the guide rail 54 along the extension direction of the guide rail 54. The side of the guide groove 541 facing away from the bottom surface 542 is open to engage with the slide seat 52.

[0042] In some embodiments, the seat 100 may further include a drive mechanism, which may be disposed between the seat cushion 12 and the floor 2012. The drive mechanism is drively connected to the sliding seat 52 and is used to drive the sliding seat 52 to move along the guide rail 54 to change the position of the seat body 10. The occupant can control the seat 100 to slide back and forth (along the guide rail 54) through the drive mechanism to meet the seating needs. The drive mechanism may include a drive source such as a motor or cylinder, and may also include a transmission structure such as a worm gear, rack and pinion, or lead screw.

[0043] Please also refer to Figure 4 and Figure 6The seat slide rail assembly 50 may further include a guide rod 56 and a guide mounting seat 58. The guide rod 56 is fixedly connected to the guide rail 54 via the guide mounting seat 58, and the sliding seat 52 is slidably connected to the guide rod 56. The guide mounting seat 58 is used to mount the guide rod 56, and there may be two guide mounting seats 58, which are respectively located at opposite ends of the guide rail 54. The guide mounting seat 58 is fixedly connected to the bottom surface 542 of the groove, for example, by fasteners such as screws or bolts. The guide rod 56 is connected between the two guide mounting seats 58. The guide rod 56 is located in the guide groove 541 and passes through the embedded part of the sliding seat 52. The guide rod 56 and the sliding seat 52 can slide together. When the drive mechanism of the seat 100 drives the seat body 10 to adjust, the sliding seat 52 drives the seat body 10 to slide along the guide rail 54. The guide rod 56 provides further guidance for the sliding seat 52, improving the stability of the seat slide rail assembly 50. The guide rod 56 also prevents some fallen items 300 from falling onto the bottom surface 542 of the groove, thus affecting the movement of the seat slide rail assembly 50.

[0044] In this embodiment, the surface of the guide rod 56 away from the bottom surface 542 is designated as the support surface 561, and the surface of the guide mounting base 58 away from the bottom surface 542 is designated as the first surface 581. The maximum distance between the support surface 561 and the bottom surface 542 is greater than the maximum distance between the first surface 581 and the bottom surface 542, and the support surface 561 forms the support portion 501. This specification does not limit the specific structural shape of the guide rod 56. For example, the guide rod 56 can be a round rod or a square rod. If the guide rod 56 is a round rod or other irregularly shaped rod, then the "maximum distance between the support surface 561 and the bottom surface 542" is understood as the distance between the plane containing the highest point of the guide rod 56 relative to the bottom surface 542 and the bottom surface 542. Similarly, the "maximum distance between the first surface 581 and the bottom surface 542" is understood as the distance between the plane containing the highest point of the guide mounting base 58 relative to the bottom surface 542 and the bottom surface 542.

[0045] The support surface 561 serves as a support part 501 to support the dropped item 300 that falls onto the guide rail 54. When the dropped item 300 lands on the support surface 561, the sliding seat 52 can push the dropped item 300 to slide on the support surface 561. In this embodiment, the protrusion height of the guide mounting seat 58 relative to the bottom surface 542 of the groove is less than the protrusion height of the guide rod 56 relative to the bottom surface 542 of the groove. Even if the dropped item 300 is pushed to the guide mounting seat 58 by the sliding seat 52, there will be no situation where the guide mounting seat 58 blocks the dropped item 300 and squeezes the dropped item 300 together with the sliding seat 52. This reduces the possibility of damaging the dropped item 300 and also reduces the risk of the vehicle 200 catching fire when the dropped item 300 is a dangerous good and is squeezed.

[0046] In other embodiments, the support surface 561 is flush with the first surface 581, and the support surface 561 and the first surface 581 together form the support portion 501. The upper surface of the guide mounting seat 58 and the upper surface of the guide rod 56 are flush and together form the support portion 501. Items that fall onto the guide rail 54 are supported by the support portion 501. When the sliding seat 52 slides relative to the guide rail 54, it pushes the fallen item 300 to move, passing through the support surface 561 and the first surface 581 in sequence before sliding out of the guide rail 54, and will not be damaged by compression.

[0047] In this embodiment, the seat 100 serves as the front seat of the vehicle 200. To ensure the adjustment range of the seat 100, the guide rail 54 typically extends to the side of the seat back 14 near the rear seat of the vehicle 200. If the items of the occupants on the rear seat fall onto the seat rail assembly 50, the items will not be crushed or damaged under the support of the support 501 and the pushing action of the sliding seat 52, thus reducing the risk of the vehicle 200 catching fire due to being crushed when the fallen items are dangerous goods.

[0048] The seat slide rail assembly 50 may further include a fastener 59, which passes through the bottom surface 542 of the groove and is used for fixed connection with the floor 2012. The fastener 59 is located on the side of the guide mounting seat 58 opposite to the guide rod 56 and protrudes relative to the bottom surface 542 of the groove. The fastener 59 is positioned close to the guide mounting seat 58. The fastener 59 is used to fix the guide rail 54 to the floor 2012 (e.g., Figure 2 As shown, the fixing member 59 can be a bolt. The bolt head of the fixing member 59 is located on the bottom surface 542 of the groove, and the threaded part of the fixing member 59 passes through the bottom surface 542 of the groove and connects with the floor 2012. When the sliding seat 52 slides on the guide rail 54, when the sliding seat 52 pushes the dropped item 300 off the first surface 581 of the guide mounting seat 58, one end or part of the dropped item 300 may fall between the guide mounting seat 58 and the fixing member 59. At this time, when the sliding seat 52 continues to move, due to the change in the force direction of the dropped item 300, it will not be squeezed between the sliding seat 52 and the fixing member 59. On the other hand, the fixing member 59 is set close to the guide mounting seat 58, and the distance between the two is small, which greatly reduces the possibility of the dropped item 300 falling between the fixing member 59 and the guide mounting seat 58.

[0049] The number of fasteners 59 can be set to multiple, and multiple fasteners 59 can be distributed at opposite ends of the guide rail 54. Multiple fasteners 59 can improve the connection stability between the guide rail 54 and the floor 2012.

[0050] Please also refer to Figure 7 and Figure 8In this embodiment, the seat slide rail assembly 50 may further include a support end cap 510. The support end cap 510 is connected to the guide mounting seat 58 and covers the fixing member 59. The side surface of the support end cap 510 away from the bottom surface 542 is a second surface 5101. The maximum distance between the second surface 5101 and the bottom surface 542 is less than or equal to the maximum distance between the first surface 581 and the bottom surface 542. Here, "the maximum distance between the second surface 5101 and the bottom surface 542" is understood as the distance between the plane containing the highest point of the support end cap 510 relative to the bottom surface 542 and the bottom surface 542.

[0051] The height of the second surface 5101 of the support end cap 510 relative to the bottom surface 542 of the groove is not higher than the height of the first surface 581 relative to the bottom surface 542 of the groove. This ensures that the falling item 300 is pushed to the support end cap 510 by the sliding seat 52, and that the support end cap 510 does not block the falling item 300 and together with the sliding seat 52 squeeze the falling item 300, reducing the possibility of damaging the falling item 300. Furthermore, the support end cap 510 covers the fixing member 59, preventing the falling item 300 from falling between the guide mounting seat 58 and the fixing member 59 during the pushing process by the sliding seat 52, allowing the falling item 300 to be directly pushed away from the guide rail 54 by the sliding seat 52. In this embodiment, the side of the support end cap 510 facing the fixing member 59 may have a receiving groove to accommodate the fixing member 59.

[0052] To facilitate the installation of the guide rod 56 and the support end cap 510, the guide mounting base 58 is provided with a mounting slot 583. The mounting slot 583 has a first end 5832 and a second end 5834 facing away from each other. The guide rod 56 is inserted into the first end 5832, and the support end cap 510 is inserted into the second end 5834. The guide mounting base 58 is a sheet metal part. The mounting slot 583 extends through the guide mounting base 58 along the extension direction of the guide rail 54, and the guide mounting base 58 is open on the side facing away from the bottom surface 542 of the groove, so that the upper surface of the guide mounting base 58 (the side facing away from the bottom surface 542 of the groove, i.e., the first surface 581) will not be higher than the support surface 561 of the guide rod 56. The end of the guide rod 56 is inserted into the mounting slot 583 via the first end 5832, and the end of the guide mounting base 58 is inserted into the mounting slot 583 via the second end 5834. The structure is simple and the installation is convenient.

[0053] In this embodiment, the seat slide rail assembly 50 may further include a protective shell 53, which is fitted onto the end of the guide rail 54. The protective shell 53 has an opening 532 communicating with the guide groove 541, and the opening 532 extends through the protective shell 53 along the extending direction of the guide rail 54. A fastener 59 is sequentially inserted through the bottom surface 542 of the groove, the protective shell 53, and the floor 2012, securing the three together. The protective shell 53, located at the end of the guide rail 54, covers the sharp parts of the guide rail 54, preventing occupants from getting cut on their hands or feet when adjusting the seat 100 or picking up dropped items 300, while also enhancing the aesthetics of the seat slide rail assembly 50.

[0054] To improve the stability of the seat body 10, two seat slide rail assemblies 50 can be provided, with the two seat slide rail assemblies 50 respectively located on both sides of the bottom of the seat cushion 12.

[0055] In the seat 100 provided in this application, the shielding component 30 at least partially shields the drop space 205. When a larger object 300 falls, it will land on the shielding component 30, reducing the possibility of the object 300 falling into the drop space 205. If the object 300 falls onto the guide rail 54, the support portion 501 protruding from the bottom surface 542 of the groove will support the object 300. When the position of the seat body 10 is adjusted, the sliding seat 52 will slide on the guide rail 54. During the movement, the sliding seat 52 moves on the surface of the support portion 501 away from the bottom surface 542 of the groove, thereby pushing the object 300 supported by the support portion 501 to slide on the support portion 501. The seat 100 in this embodiment supports the dropped item 300 through the support part 501, reducing the possibility of the dropped item 300 falling onto the bottom surface 542 of the groove. This ensures that when the seat body 10 adjusts its position and the sliding seat 52 slides relative to the guide rail 54, it will not compress or damage the dropped item 300. It also reduces the risk of the vehicle 200 catching fire when the dropped item 300 is a dangerous item and is compressed.
