Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] In the embodiments of this application, the terms "upper," "lower," "inner," "middle," "outer," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for better description of this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation. Furthermore, some of the above terms may be used to indicate other meanings besides orientation or positional relationship; for example, the term "upper" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in the embodiments of this application according to the specific circumstances.

[0043] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0044] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0045] In this application, the terms "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions.

[0046] Unless otherwise stated, the term "multiple" means two or more.

[0047] In passenger trains such as high-speed trains and buses, seats are equipped with foldable tables, which passengers can unfold for dining or work. Currently, the table fixing system mostly uses a knob-type snap-fit ​​structure. For the table to fold up, the table and seat must be precisely aligned, and then the knob is rotated to mechanically lock the table in place. Because this precise alignment is required for folding, the table cannot be quickly retracted, thus affecting user convenience.

[0048] Therefore, to address the technical problems of the existing technology, a knob-type latching structure is no longer used. Instead, a baffle is employed to achieve rapid tabletop retraction. Specifically, a tabletop holder with a cavity is provided, allowing the tabletop to be placed within it. A limit baffle and a telescopic component are included, with the limit baffle and telescopic component fixedly connected. The telescopic component controls the movement of the limit baffle. Furthermore, a limit slot is provided on the tabletop holder to position the limit baffle. When the tabletop is to be retracted, it can be pushed into the cavity of the tabletop holder. The telescopic component then drives the limit baffle to move along the limit slot in a first direction, thus preventing the tabletop from moving in a second direction, causing it to fall out of the cavity. This achieves rapid retraction and improves the user experience.

[0049] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0050] Figure 1 This is a schematic diagram of the structure of a fastener connection device provided in an embodiment of this application, with reference to... Figure 1 As shown, the fastener connection device specifically includes: a tabletop holder 1, a limiting baffle 2, and a telescopic component 3.

[0051] Specifically, the telescopic component 3 is fixedly connected to the limiting baffle 2; the tabletop holder 1 is provided with a cavity; the tabletop holder 1 is detachably connected to the telescopic component 3; the tabletop holder 1 is provided with a limiting slot 10; the telescopic component 3 drives the limiting baffle 2 to move in the first direction to restrict the tabletop from moving in the second direction, and the first direction and the second direction intersect.

[0052] Among them, the limiting baffle 2 is used to limit the table.

[0053] The telescopic component 3 is used to control the movement of the limit baffle 2, thereby limiting and releasing the limit on the table.

[0054] The cavity is used to place the table.

[0055] The limiting slot 10 is used to position the limiting baffle 2.

[0056] Optionally, the fixed connection can be welding, screw fixing, bonding, etc., and this embodiment is not limited to any particular method.

[0057] Optionally, the detachable connection may be via a threaded interface, etc., which is not limited in this embodiment.

[0058] Optionally, the limiting baffle 2 can be made of a material with high strength and wear resistance, such as steel, stainless steel or high-strength engineering plastics.

[0059] Optionally, the tabletop tray 1 can be made of wood, metal (such as aluminum or steel), or high-strength plastic, etc., and this embodiment does not impose any limitations.

[0060] Specifically, in this embodiment, if the tabletop is to be stopped, the tabletop is pushed into the cavity of the tabletop holder 1, and the stopping baffle 2 is embedded in the stopping slot 10 of the tabletop holder 1. The telescopic component 3 drives the stopping baffle 2 to move into the cavity of the tabletop holder 1 along a direction parallel to the extending direction of the stopping slot 10, thereby forming a physical barrier to prevent the tabletop from falling out of the cavity, thus stopping the tabletop. If the tabletop is to be stopped, the telescopic component 3 drives the stopping baffle 2 to move out of the cavity of the tabletop holder 1 along a direction parallel to the extending direction of the stopping slot 10, thereby allowing the tabletop to be moved out of the cavity of the tabletop holder 1 and unlocking the tabletop.

[0061] Reference Figure 1 As shown, the first direction is the lateral extension direction of the limiting slot 10, which can be pushed and pulled in the first direction. The second direction is a unidirectional direction perpendicular to the first direction, and the second direction intersects with the first direction.

[0062] Specifically, a cavity is provided in the tabletop holder 1 to support the tabletop, and the tabletop holder 1 is detachably connected to the telescopic component 3, thereby facilitating the installation, maintenance, and replacement of parts of the telescopic component 3 and improving the flexibility of the device. Furthermore, the limiting baffle 2 can be limited by the limiting slot 10 of the tabletop, and can be driven by the telescopic component 3 to move in the first direction, thereby restricting the movement of the tabletop in the second direction and ensuring that the tabletop stops at a predetermined position, thus achieving rapid limiting of the tabletop and improving the user experience.

[0063] Figure 2 This is a schematic diagram of the structure of the telescopic component 3 provided in an embodiment of this application, with reference to... Figure 2 As shown in the figure, as an optional implementation, based on the above embodiment, the telescopic component 3 includes a positioning bracket 30, a first telescopic rod 31, and a guide seat 32;

[0064] One end face of the positioning bracket 30 near the tabletop bracket 1 is detachably connected to the tabletop bracket 1; one end of the first telescopic rod 31 is connected to the other end face of the positioning bracket 30, the other end of the first telescopic rod 31 is connected to one end face of the guide seat 32, the other end face of the guide seat 32 is connected to the limiting baffle 2, and the extension direction of the first telescopic rod 31 is parallel to the first direction.

[0065] One end face of the positioning bracket 30 is detachably connected to the table bracket 1, providing a stable installation base for the telescopic component 3.

[0066] The first telescopic rod 31 is the driving part of the telescopic assembly 3, and its telescopic movement can drive the guide seat 32 and the limiting baffle 2 to move.

[0067] The guide seat 32 is used to provide support and guidance for the limit baffle 2, ensuring that the limit baffle 2 remains stable and accurate during movement.

[0068] The positioning bracket 30 and the table bracket 1 can be detachably connected by a buckle or by a strong magnet.

[0069] Optionally, the fixed connection can be welding, bonding, etc., and this embodiment is not limited to any particular method.

[0070] Optionally, the positioning bracket 30 may be made of a material with high strength and wear resistance, such as steel, stainless steel or high-strength engineering plastics.

[0071] Optionally, the guide seat 32 may be made of wood, metal (such as aluminum, steel), or high-strength plastic, etc., and this embodiment is not limited.

[0072] Optionally, the first telescopic rod 31 may be made of a material with high strength and wear resistance, such as steel or stainless steel.

[0073] Specifically, one end face of the positioning bracket 30 is detachably connected to the table bracket 1, the other end face of the positioning bracket 30 is fixedly connected to one end face of the first telescopic rod 31, the other end face of the first telescopic rod 31 is fixedly connected to one end face of the guide seat 32, the other end face of the guide seat 32 is fixedly connected to one end face of the limiting baffle 2, and the end face of the guide seat 32 connected to the limiting baffle 2 intersects perpendicularly with the end face of the guide seat 32 connected to the first telescopic rod 31.

[0074] Specifically, in this embodiment, the positioning bracket 30 and the tabletop bracket 1 are connected. When the first telescopic rod 31 is partially stretched, the limiting baffle 2 is located in the limiting slot 10 and does not extend beyond the limiting slot 10 into the cavity. When limiting the tabletop, the first telescopic rod 31 can be compressed to shorten it, thereby driving the guide seat 32 and the limiting baffle 2 to move in the first direction and enter the cavity of the tabletop bracket 1, thus limiting the tabletop. When releasing the tabletop, the first telescopic rod 31 is stretched outward to move the limiting baffle 2 out of the cavity of the tabletop bracket 1, thereby allowing the tabletop to move in the second direction.

[0075] Specifically, by controlling the extension and retraction of the first telescopic rod 31, the position of the limiting baffle 2 can be precisely adjusted and the operation is convenient. The design of the cooperation between the first telescopic rod 31 and the guide seat 32 ensures that the limiting baffle 2 can remain stable and accurate during movement, thereby improving the stability of the entire device.

[0076] refer to Figure 2 As shown in the figure, as an optional implementation, based on any of the above embodiments, the telescopic assembly 3 further includes a second telescopic rod 33; one end face of the guide seat 32 is connected to one end of the second telescopic rod 33, the extension direction of the second telescopic rod 33 is perpendicular to the extension direction of the first telescopic rod 31, the other end of the second telescopic rod 33 is connected to the limiting baffle 2, and the second telescopic rod 33 drives the limiting baffle 2 to move in the second direction.

[0077] Optionally, the second telescopic rod 33 may be made of a material with high strength and wear resistance, such as steel or stainless steel.

[0078] Specifically, one end face of the guide seat 32 is fixedly connected to one end of the second telescopic rod 33, the other end of the second telescopic rod 33 is connected to the limiting baffle 2, and the end face of the guide seat 32 connected to one end of the first telescopic rod 31 and the end face connected to one end of the second telescopic rod 33 intersect perpendicularly.

[0079] For example, such as Figure 2 As shown, the guide seat 32 is cuboid in shape. One end of the first telescopic rod 31 is connected to one end face of the guide seat 32, and the other end face of the guide seat 32 is connected to one end of the second telescopic rod 33. The other end of the second telescopic rod 33 is connected to one end face of the limiting baffle 2, so that the extension direction of the limiting baffle 2 is parallel to the extension direction of the first telescopic rod 31, and the extension direction of the limiting baffle 2 is perpendicular to the extension direction of the second telescopic rod 33.

[0080] Specifically, in this embodiment, the guide seat 32 and the limiting baffle 2 are connected by the second telescopic rod 33. In the normal state of the second telescopic rod 33, the limiting baffle 2 can be embedded in the limiting slot 10. If the limiting baffle 2 is to be moved out of the limiting slot 10, the second telescopic rod 33 is stretched so that the limiting baffle 2 moves in the second direction, thereby moving out of the limiting slot 10.

[0081] Specifically, by providing a second telescopic rod 33 in the telescopic assembly 3, the position of the limiting baffle 2 in the second direction can be adjusted by the second telescopic rod 33, thereby adapting to tabletops of different sizes or installation deviations.

[0082] Figure 3 This is a structurally exploded schematic diagram of a fastener connection device provided in an embodiment of this application, with reference to... Figure 3 As shown in the diagram, as an optional implementation, based on any of the above embodiments, the tabletop bracket 1 is provided with a mounting slot 11. The mounting slot 11 and the limiting slot 10 are located on the outer side of the tabletop bracket 1, and the end face with the mounting slot 11 and the end face with the limiting slot 10 are adjacent and intersect. The mounting slot 11 and the positioning bracket 30 are connected.

[0083] The mounting slot 11 is used to connect with the positioning slot 30.

[0084] Optionally, the shape of the mounting slot 11 can be cylindrical or cuboid, etc., and is not limited in this embodiment.

[0085] For example, the shape and size of the mounting slot 11 may be the same as those of the positioning slot 30, and the mounting slot 11 is plugged into the positioning slot 30.

[0086] For example, such as Figure 3 As shown, the positioning bracket 30 can be placed in the mounting slot 11, which is located on the outer side of the tabletop bracket 1 and is symmetrically opened at both ends of the tabletop bracket 1. The end face of the limiting slot 10 and the end face of the mounting slot 11 are adjacent to and intersect each other. When the positioning bracket 30 is connected to the mounting slot 11, the limiting baffle 2 connected to one end of the telescopic component 3 can be placed in the limiting slot 10.

[0087] Specifically, by setting an installation slot 11 on the tabletop card holder 1, installation errors can be reduced when connecting with the positioning card holder 30. Furthermore, the installation slot 11 and the limiting slot 10 are distributed in an L-shape to form a bidirectional limiting structure. This allows the limiting baffle 2 to be embedded in the limiting slot 10 after the installation slot 11 is connected to the positioning card holder 30, reducing installation errors and ensuring precise alignment between components.

[0088] refer to Figure 3As shown in the figure, as an optional implementation, based on any of the above embodiments, the table card holder 1 is provided with a magnetic block groove 12, the magnetic block groove 12 is connected to the mounting card groove 11, the positioning card holder 30 is provided with a first magnetic block 301, one end face of the positioning card holder 30 near the mounting card groove 11 is fixedly connected to one end face of the first magnetic block 301, and a second magnetic block 4 is provided in the magnetic block groove 12, the other end face of the first magnetic block 301 and one end face of the second magnetic block 4 attract each other.

[0089] The magnetic block slot 12 is used to accommodate the second magnetic block 4 and the first magnetic block 301.

[0090] One end face of the first magnetic block 301 is fixedly connected to one end face of the positioning card seat 30.

[0091] Optionally, the fixed connection can be adhesive bonding or other methods, which are not limited in this embodiment.

[0092] The first magnetic block 301 is a magnetic block connected to the positioning card holder 30, and the second magnetic block 4 is a magnetic block placed in the magnetic block slot 12 and connected to the first magnetic block 301.

[0093] In this configuration, the magnetic poles of the first magnetic block 301 are opposite to those of the second magnetic block 4, forming a closed magnetic circuit to enhance the attraction force.

[0094] Specifically, the magnetic block groove 12 is formed on the side wall of the mounting slot 11 of the tabletop card holder 1. A second magnetic block 4 is embedded inside the magnetic block groove 12. The second magnetic block 4 is fixedly connected to the magnetic block groove 12. The first magnetic block 301 is fixedly connected to one end face of the positioning card holder 30 near the mounting slot 11. The other end face of the first magnetic block 301 and one end face of the second magnetic block 4 attract each other.

[0095] Optionally, the second magnetic block 4 can be fixedly connected to the magnetic block slot 12 by means of adhesive bonding, etc., which is not limited in this embodiment.

[0096] Specifically, in this embodiment, the side wall of the mounting slot 11 of the tabletop bracket 1 is provided with a magnetic block slot 12, which communicates with the mounting slot 11. A first magnetic block 301 is provided on one end face of the positioning bracket 30 near the mounting slot 11, and a second magnetic block 4 is provided in the magnetic block slot 12. When the telescopic assembly 3 connected to the limit baffle 2 is installed on the tabletop bracket 1, the positioning bracket 30 is positioned according to the magnetic block slot 12 and the mounting slot 11. The first magnetic block 301 and the positioning bracket 30 connected to the first magnetic block 301 are placed in the magnetic block slot 12 and the mounting slot 11. The first magnetic block 301 and the second magnetic block 4 attract each other, thereby realizing the installation of the telescopic assembly 3 connected to the limit baffle 2 on the tabletop bracket 1. The assembly can be disassembled by separating the first magnetic block 301 and the second magnetic block 4.

[0097] Specifically, by providing a magnetic block groove 12 in the tabletop card holder 1, setting a first magnetic block 301 on the positioning card holder 30, and setting a second magnetic block 4 in the magnetic block groove 12, the positioning card holder 30 can be accurately positioned to the predetermined position during installation due to the attraction between the magnetic blocks. This significantly improves the connection strength and stability between the positioning card holder 30 and the tabletop card holder 1. Furthermore, by separating the first magnetic block 301 and the second magnetic block 4, the telescopic component 3 of the connecting limit baffle 2 can be disassembled and installed, improving the convenience of operation.

[0098] refer to Figure 3 As shown in the figure, as an optional implementation, based on any of the above embodiments, the top of the second magnetic block 4 is provided with a stretching component 5, the top of the magnetic block groove 12 of the table card seat 1 is provided with a through hole 13, the through hole 13 communicates with the magnetic block groove 12, and the stretching component 5 passes through the through hole 13 through the table card seat 1 and connects with the second magnetic block 4.

[0099] The stretching component 5 is used to adjust the position of the second magnetic block 4.

[0100] The through hole 13 is located at the top of the magnetic block slot 12 and is connected to the magnetic block slot 12. The stretching component 5 can pass through the through hole 13 through the table base 1 and be directly connected to the second magnetic block 4.

[0101] For example, the telescopic assembly 5 may include a pull cord and a pull ring. One end of the pull cord is connected to the top of the second magnetic block 4. The pull cord passes through the through hole 13 from the top of the tabletop holder 1 and is connected to the pull ring. The user can pull the pull ring to tighten the pull cord, thereby pulling the second magnetic block 4 upward, thus releasing the magnetic attraction between the second magnetic block 4 and the first magnetic block 301, and achieving quick disassembly of the telescopic assembly 3.

[0102] When the telescopic component 3 and the tabletop seat 1 are connected, the second magnetic block 4 and the first magnetic block 301 are attracted to each other, and the pull rope is loosened.

[0103] Optionally, the pull rope can be bonded to the second magnetic block 4, or the pull rope can be embedded in the second magnetic block 4, etc., which is not limited in this embodiment.

[0104] There is a movable space on the top of the second magnetic block 4, and the second magnetic block 4 can be separated from the first magnetic block 301 by entering the movable space.

[0105] Understandably, the size of the through hole 13 should be smaller than the size of the magnetic block slot 12.

[0106] Specifically, in this embodiment, the stretching component 5 passes through the through hole 13 through the tabletop holder 1 and protrudes from the top of the tabletop holder 1. The top of the stretching component 5 is provided with an operating handle, which allows the second magnetic block 4 to be adjusted by external operation. The stretching component 5 can drive the second magnetic block 4 to move and separate it from the first magnetic block 301, thereby releasing the magnetic attraction between the second magnetic block 4 and the positioning holder 30 and achieving quick disassembly.

[0107] Specifically, by setting the stretching component 5, the first magnetic block 301 and the second magnetic block 4 can be quickly separated through external operation, thereby enabling the quick disassembly of the positioning card holder 30 and the table card holder 1.

Figure 5 This is a schematic diagram of the connection between the tensioning component 5 and the positioning bracket 30 according to an embodiment of this application. (Refer to...) Figure 4 and Figure 5 As shown, as an optional implementation, based on any of the above embodiments, the tensioning assembly 5 includes a pull rod 50, an elastic element 51, and a connecting rod 52. One end of the pull rod 50 is fixedly connected to the top of the second magnetic block 4, and the other end of the pull rod 50 is fixedly connected to one end of the elastic element 51. The other end of the elastic element 51 is fixedly connected to one end of the connecting rod 52. The magnetic block groove 12 opened in the table card holder 1 is an L-shaped magnetic block groove. The table card holder 1 is provided with an elastic element movable groove 14 connected to the top of the L-shaped magnetic block groove. The top of the elastic element movable groove 14 is provided with a through hole 13 communicating with the top of the table card holder 1. The elastic element movable groove 14 is used to place the elastic element 51.

[0109] The L-shaped magnetic block slot is used to accommodate the magnetic block and provide movement space for the second magnetic block 4. The elastic element 51 is used to provide a restoring force. The elastic element movable slot 14 is used to place the elastic element 51 and provide movement space for the elastic element 51.

[0110] Optionally, the elastic element 51 may be a spring or the like, but this embodiment is not limited to that.

[0111] Combination Figure 4 As shown, the side wall of the mounting slot 11 is provided with an L-shaped magnetic block slot, the mounting slot 11 is connected to the L-shaped magnetic block slot, the top of the L-shaped magnetic block slot is provided with an elastic element movable slot 14, the elastic element movable slot 14 is connected to the L-shaped magnetic block slot, the top of the elastic element movable slot 14 is provided with a through hole 13, and the elastic element movable slot 14 is connected to the through hole 13.

[0112] Combination Figure 5As shown, one end of the pull rod 50 is fixedly connected to the top of the second magnet 4, the other end of the pull rod 50 is fixedly connected to one end of the elastic member 51, the other end of the elastic member 51 is fixedly connected to one end of the pull rod 50, the other end of the pull rod 50 extends out from the through hole 13, and the pull rod 50 has a pull plate to provide a force-bearing position, serving as a tension handle.

[0113] Combination Figure 4 and Figure 5 As shown, the L-shaped magnetic block slot provides movement space for the second magnetic block 4. The user pulls the pull plate via the exposed pull rod 50, causing the elastic element 51 to compress within the elastic element movable slot 14. This causes the second magnetic block 4, connected to the elastic element 51 via the pull rod 50, to move towards the top of the tabletop holder 1, thus eliminating the attraction between the second magnetic block 4 and the first magnetic block 301. This separates the positioning holder 30, along with the first magnetic block 301, from the tabletop holder 1. Releasing the pull rod 50 restores the elasticity of the elastic element 51, allowing the second magnetic block 4 to move to its initial position connected to the first magnetic block 301. During reinstallation, the positioning holder 30 is placed into the mounting slot 11, and the first magnetic block 301 and the second magnetic block 4 attract each other, connecting the positioning holder 30 and the tabletop holder 1.

[0114] Specifically, through the combination of pull rod 50, elastic element 51, and connecting rod 52, the user can apply additional pressure from the outside to adjust the position of the second magnetic block 4, thereby controlling the attractive force between the first magnetic block 301 and the second magnetic block 4. The elastic element provides necessary cushioning and allows for automatic reset. The pull rod 50 facilitates user operation, enabling quick disassembly and maintenance of the positioning bracket 30.

[0115] refer to Figure 1 As shown, as an optional implementation, based on any of the above embodiments, the width of the limiting baffle 2 and the width of the limiting slot 10 are equal.

[0116] Specifically, the width of the limiting baffle 2 in the limiting slot 10 is equal to the width of the limiting slot 10. The limiting baffle 2 can achieve more precise positioning within the limiting slot 10, thereby reducing any unnecessary gaps or looseness.

[0117] The fixed connection methods in all the above embodiments include, but are not limited to, welding, bonding, bolt and nut connection, snap-fit ​​connection, etc.

[0118] The second aspect of this application provides a seat accessory device, including the fastener connection device and the table described above. The fastener connection device is located on the outer end face of the backrest of the seat body and is used to fix the table to the outer end face of the backrest of the seat body.

[0119] Specifically, in this embodiment, the fastener connection device can quickly lock the table to the outer end face of the seat and quickly release the table, thereby improving the convenience of table retraction and allowing for quick disassembly of the tensioning component 5 connected to the limiting baffle 2 for easy maintenance.

[0120] A third aspect of this application provides a seat, including the aforementioned seat accessories and seat body, wherein the seat accessories are located on the outer end face of the backrest of the seat body.

[0121] Specifically, in this embodiment, by integrating the seat accessories and the seat, space is saved, and the table can be released to meet the needs of dining or working, thereby improving the user experience.
