Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a table, a seat, and a vehicle. Background Technology

[0002] As vehicle technology advances, many passengers require tray tables for placing items such as mobile phones and water bottles, which are becoming increasingly popular. However, existing tray tables are relatively small, offering limited space for storing items.

[0003] In existing technologies, the tabletop is extended to give it a larger load-bearing area.

[0004] However, in the existing technology, there are steps between the extended tabletops. When passengers accidentally place their items on the steps, the items may slip due to instability. Utility Model Content

[0005] This application provides a table, a seat, and a vehicle to at least address the problem of poor table stability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] In a first aspect, a tabletop is provided. The tabletop is used for a seat, the seat including a seat body. The tabletop includes a first tabletop and a second tabletop. The first tabletop is adapted to connect with the seat. The first tabletop includes a first top surface, a side surface, and a receiving cavity with an opening disposed on the side surface. The first tabletop includes a second top surface. The second tabletop is slidably connected to the first tabletop through the opening and slides between a first state and a second state. When the second tabletop is in the first state, at least a portion of the second tabletop is located within the receiving cavity. When the second tabletop is in the second state, the second tabletop is located outside the receiving cavity, and the second top surface is coplanar with the first top surface.

[0008] According to the above technical solution, the second tabletop can slide out from the receiving cavity of the first tabletop. When the second tabletop is in the second state, the overall load-bearing area of ​​the tabletop increases, providing a larger placement surface. The second top surface is coplanar with the first top surface, making the placement of items more stable when passengers place them, preventing instability and slippage due to steps, thus improving the safety and stability of the tabletop.

[0009] In one possible implementation, the tabletop further includes a drive assembly. The drive assembly is connected between the second tabletop and the first tabletop, and drives the second tabletop to switch between a first state and a second state.

[0010] The sliding position of the second tabletop can be precisely controlled by the drive component, so that the second tabletop can reach the second state when it slides out, thereby making the second top surface coplanar with the first top surface. This reduces the errors that may occur during manual operation, ensures the flatness and stability of the tabletop during use, and further improves the safety of placing items.

[0011] In one possible implementation, the drive assembly includes a base and a resilient lifting assembly. The base is movably connected to a first tabletop and can slide between a first position and a second position. The second tabletop is connected to the base via the resilient lifting assembly, which can switch between a compressed state and a lifted state. When the base is in the first position, the resilient lifting assembly is in a compressed state, and the resilient lifting assembly, the second tabletop, and the base are all located within a receiving cavity, thus placing the second tabletop in the first state. When the base is in the second position, the resilient lifting assembly is in a lifted state, and the portion of the resilient lifting assembly, the second tabletop, and the base that supports the resilient lifting assembly are all located outside the receiving cavity, thus placing the second tabletop in the second state.

[0012] The flexible lifting mechanism makes the unfolding and repositioning of the second table smoother. When the base slides to the second position, the flexible lifting mechanism changes from a compressed state to a lifted state, automatically pushing the second table out of the receiving cavity into its usable state. When it is time to fold up the second table, pushing the base back to the first position compresses the flexible lifting mechanism, and the second table returns to its receiving cavity. This reduces manual operation steps for passengers, making it more convenient to use.

[0013] In one possible implementation, the elastic lifting assembly includes a base plate, a cover, and an elastic element. The base plate is fixedly connected to a base. The cover is connected to a second tabletop. The elastic element is connected between the base plate and the cover and is elastically expandable and contractible in a direction perpendicular to the second top surface. The elastic deformation of the elastic element is greater when the second tabletop is in a first state than when the second tabletop is in a second state.

[0014] When the table needs to be unfolded, as the base slides to the second position, the elastic deformation of the elastic element decreases, gradually restoring and lifting the second table to the second state, so that the second top surface is coplanar with the first top surface. The elastic element is arranged in a direction perpendicular to the second top surface, which can provide a vertically upward stabilizing force when lifting the second table, so that the second table remains stable during the rising process.

[0015] In one possible implementation, the elastic element is a torsion spring.

[0016] The torsion spring has excellent elastic properties and can store a large amount of elastic potential energy under compression. When the base slides from the first position to the second position, the torsion spring quickly releases the elastic potential energy, providing a strong lifting force for the second tabletop, allowing it to quickly and stably pop out of the accommodating cavity to the second state.

[0017] In one possible implementation, the drive assembly further includes a resilient telescopic member. The resilient telescopic member is connected between the first tabletop and the resilient lifting assembly. The resilient telescopic member allows the resilient lifting assembly and the second tabletop to move through an opening from inside the receiving cavity to outside the receiving cavity. When the resilient lifting assembly and the second tabletop are outside the receiving cavity, the resilient telescopic member has an elastic restoring force that applies towards the resilient lifting assembly, pointing inwards into the receiving cavity.

[0018] When it is necessary to restore the second table from the second state to the first state, the elastic restoring force of the elastic telescopic member can assist the elastic lifting assembly and the second table in moving into the receiving cavity. This facilitates the movement of the second table into the receiving cavity.

[0019] In one possible implementation, the elastic telescopic element is a coil spring. The drive assembly also includes a rotating element. The rotating element is rotatably connected to the base. One end of the coil spring is wound around the rotating element.

[0020] The rotating component provides a fixed position for the coil spring. The coil spring can store a large amount of elastic potential energy during stretching or torsion. When the second table needs to reset from the second state to the first state, the coil spring can quickly release the elastic potential energy, providing a strong reset force for the second table, so that the reset action is rapid and reliable.

[0021] In one possible implementation, the drive assembly further includes a limiting member. The limiting member is connected to the base and has a limiting groove. The limiting groove extends along the sliding direction of the second tabletop. The unfolded portion of the coil spring is located within the limiting groove.

[0022] The limiting groove extends along the sliding direction of the second table, providing a guide path for the unfolding and retraction of the coil spring. In this way, the coil spring can move in a predetermined direction during operation, reducing the possibility of twisting, tangling, or deviating during extension and retraction, thus enabling the coil spring to stably exert its elastic effect and provide stable power for the movement of the second table.

[0023] In a second aspect, a seat is provided, comprising a seat body and a table provided in any possible embodiment of the first aspect. A first tabletop is connected to the seat body.

[0024] Thirdly, a vehicle is provided, including a table provided in any possible embodiment of the first aspect, or a seat provided in any possible embodiment of the second aspect.

[0025] The beneficial effects of this application are:

[0026] (1) The second tabletop can slide out from the receiving cavity of the first tabletop. When the second tabletop is in the second state, the overall load-bearing area of ​​the tabletop increases, providing a larger placement surface. The second top surface is coplanar with the first top surface, so when passengers place items, the items are placed more stably and will not be unstable or slip due to steps, thus improving the safety and stability of the tabletop.

[0027] (2) The sliding position of the second table can be precisely controlled by the drive component so that the second table can reach the second state when it slides out, thereby making the second top surface coplanar with the first top surface, reducing the possible errors of manual operation, ensuring the flatness and stability of the table when in use, and further improving the safety of placing items.

[0028] (3) The flexible lifting assembly makes the unfolding and resetting of the second table panel smoother. When the base slides to the second position, the flexible lifting assembly changes from a compressed state to a lifted state, automatically pushing the second table panel out of the receiving cavity into the usable state. When it is necessary to fold up the second table panel, the base is pushed back to the first position, the flexible lifting assembly is compressed, and the second table panel returns to the receiving cavity. In this way, the manual operation steps for passengers are reduced, making it more convenient to use.

[0029] (4) When the table needs to be unfolded, as the base slides to the second position, the elastic deformation of the elastic element decreases, gradually restoring and lifting the second table to the second state, so that the second top surface is coplanar with the first top surface. The elastic element is set in a direction perpendicular to the second top surface, which can provide a vertically upward stabilizing force when lifting the second table, so that the second table remains stable during the rising process.

[0030] (5) The torsion spring has good elastic properties and can store a large amount of elastic potential energy under compression. When the base slides from the first position to the second position, the torsion spring quickly releases the elastic potential energy, providing a strong lifting force for the second table, so that it can quickly and stably pop out of the accommodating cavity to the second state.

[0031] (6) When it is necessary to restore the second table from the second state to the first state, the elastic restoring force of the elastic telescopic member can assist the elastic lifting assembly and the second table in moving into the receiving cavity. Thus, it is convenient for the second table to move into the receiving cavity.

[0032] (7) One end of the coil spring is wound around the rotating part.

[0033] The rotating component provides a fixed position for the coil spring. The coil spring can store a large amount of elastic potential energy during stretching or torsion. When the second table needs to reset from the second state to the first state, the coil spring can quickly release the elastic potential energy, providing a strong reset force for the second table, so that the reset action is rapid and reliable.

[0034] (8) The limiting groove extends along the sliding direction of the second table, providing a guide path for the unfolding and retraction of the coil spring. In this way, the coil spring can move in a predetermined direction during operation, reducing the possibility of twisting, entanglement or deviation during the extension and retraction process, thereby enabling the coil spring to stably exert its elastic effect and provide stable power for the movement of the second table.

[0044] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model patent.

[0045] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0046] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0047] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown. This invention provides a tabletop 10. The tabletop 10 is used for a seat 20, the seat 20 including a seat body. The tabletop 10 includes a first tabletop 1 and a second tabletop 2. The first tabletop 1 is adapted to be connected to the seat 20. The first tabletop 1 includes a first top surface 11, a side surface 12, and an opening 13 in a receiving cavity 14 disposed on the side surface 12. The first tabletop 1 includes a second top surface 21. The second tabletop 2 is slidably connected to the first tabletop 1 through the opening 13 and slides between a first state and a second state. When the second tabletop 2 is in the first state, at least a portion of the second tabletop 2 is located in the receiving cavity 14. When the second tabletop 2 is in the second state, the second tabletop 2 is located outside the receiving cavity 14, and the second top surface 21 is coplanar with the first top surface 11.

[0048] According to the above technical solution, the second tabletop 2 can slide out from the receiving cavity 14 of the first tabletop 1. When the second tabletop 2 is in the second state, the overall load-bearing area of ​​the tabletop 10 increases, providing a larger placement surface. The second top surface 21 is coplanar with the first top surface 11, so when passengers place items, the items are placed more stably and will not be unstable or slip due to steps, thus improving the safety and stability of the tabletop 10.

[0049] When the second table 2 is not in use, that is, when the second table 2 is in the first state, at least partially located in the accommodating cavity 14, the table 10 occupies a small space and will not affect the spatial layout around the seat 20 too much, thus reducing the waste of space when the second table 2 is not in use.

[0050] Since the second top surface 21 and the first top surface 11 are coplanar when unfolded and in use, there are no uneven steps or gaps, making the surface of the tabletop 10 relatively flat, easier to clean, less prone to accumulating dust and dirt, and more convenient for daily maintenance, which helps to maintain a hygienic environment around the tabletop 10 and the seat 20.

[0051] The embodiments of this application will be described in detail below with reference to the accompanying drawings, and the application scenarios of the embodiments of this application will be introduced first before the detailed description of the embodiments of this application.

[0052] The tabletop 10 provided in this application can be applied to household fixtures, office spaces, and vehicles. For example, the tabletop 10 can be applied to vehicles, airplanes, railway trains, living rooms, conference rooms, open office areas, outdoor scenes, etc.

[0053] This application also provides a seat 20. The seat 20 includes a seat body and a table 10. The first table 1 of the table 10 is connected to the seat body.

[0054] See also Figure 1 For example, the number of second tabletops 2 can be set to multiple, and different second tabletops 2 can operate independently.

[0055] For example, there are two second tabletops 2, which are located at opposite ends of the first tabletop 1.

[0056] For example, the first tabletop 1 and the seat body can be connected via a bracket or directly. When a bracket is used for connection, the connection methods between the first tabletop 1 and the seat body include, but are not limited to, sliding connection and rotating connection.

[0057] The seat 20 provided in this application can be used in transportation, office spaces, homes, public places, etc.

[0058] For example, seat 20 can be used in vehicles, airplanes, trains, subways, etc. Seat 20 can also be used in offices, conference rooms, living rooms, dining rooms, bedrooms, cinemas, waiting rooms, schools, etc.

[0059] This application also provides a vehicle, including: electric vehicles, gasoline vehicles, hydrogen fuel cell vehicles, hybrid vehicles, etc., that use electricity as their energy source. The vehicle can also be a sedan, SUV, MPV, sports car, racing car, truck, engineering vehicle, special vehicle, etc., that requires the installation of seats 20.

[0060] In one possible implementation, the tabletop 10 further includes a drive assembly 3. The drive assembly 3 is connected between the second tabletop 2 and the first tabletop 1, and drives the second tabletop 2 to switch between a first state and a second state.

[0061] The sliding position of the second tabletop 2 can be precisely controlled by the drive component 3 so that the second tabletop 2 can reach the second state when it slides out, thereby making the second top surface 21 coplanar with the first top surface 11, reducing the error that may occur during manual operation, ensuring the flatness and stability of the tabletop 10 during use, and further improving the safety of placing items.

[0062] See also Figure 1 and Figure 2 In one possible implementation, the drive assembly 3 includes a base 31 and an elastic lifting assembly 32. The base 31 is movably connected to the first tabletop 1 and can slide between a first position and a second position. The second tabletop 2 is connected to the base 31 via the elastic lifting assembly 32, which can switch between a compressed state and a lifted state.

[0063] When the base 31 is in the first position, the elastic lifting component 32 is in a compressed state, and the elastic lifting component 32, the second table 2, and the base 31 are all located within the receiving cavity 14, so that the second table 2 is in the first state. When the base 31 is in the second position, the elastic lifting component 32 is in a lifting rotation state, and the portion of the elastic lifting component 32, the second table 2, and the base 31 that supports the elastic lifting component 32 is all located outside the receiving cavity 14, so that the second table 2 is in the second state.

[0064] When the base 31 is in the first position, the elastic lifting assembly 32, the second table 2, and the base 31 can all be stored in the receiving cavity 14 of the first table 1, so that the entire table 10 occupies less space when the second table 2 is not in use.

[0065] The elastic lifting component 32 makes the unfolding and resetting process of the second table 2 smoother. When the base 31 slides to the second position, the elastic lifting component 32 changes from the compressed state to the lifting state, lifting the second top surface 21 to a position coplanar with the first top surface 11.

[0066] When the second table 2 needs to be retracted, the base 31 is pushed back to the first position, the elastic lifting component 32 is compressed, causing the second table 2 to descend and return to the receiving cavity 14. This reduces the number of manual operation steps for passengers and makes it more convenient to use.

[0067] See also Figure 1 and Figure 2 In one possible implementation, the elastic lifting assembly 32 includes a base plate 321, a cover 322, and an elastic element 323.

[0068] The base plate 321 is fixedly connected to the base 31. The cover 322 is connected to the second tabletop 2. The elastic element 323 is connected between the base plate 321 and the cover 322, and can elastically extend and retract in a direction perpendicular to the second top surface 21. When the second tabletop 2 is in the first state, the elastic deformation of the elastic element 323 is greater than that when the second tabletop 2 is in the second state.

[0069] When the second tabletop 2 is in the first state, the elastic deformation of the elastic element 323 is greater than that when the second tabletop 2 is in the second state. This means that the elastic potential energy of the elastic element 323 when the second tabletop 2 is in the first state is greater than that when the second tabletop 2 is in the second state.

[0070] When the tabletop 10 needs to be unfolded, as the base 31 slides to the second position, the elastic deformation of the elastic element 323 decreases, gradually restoring and lifting the second tabletop 2 to the second state, so that the second top surface 21 is coplanar with the first top surface 11. The elastic element 323 is arranged in a direction perpendicular to the second top surface 21, which can provide a vertically upward stabilizing force when lifting the second tabletop 2, so that the second tabletop 2 remains stable during the rising process.

[0071] For example, the connection methods of the base plate 321 and the base 31 include, but are not limited to: bolt connection, snap-fit, adhesive bonding, welding, and integral molding.

[0072] For example, the elastic element 323 includes, but is not limited to: spring, elastic sheet, torsion spring.

[0073] The following explanation will use the elastic element 323 as a torsion spring.

[0074] The torsion spring has good elastic properties and can store a large amount of elastic potential energy under compression. When the base 31 slides from the first position to the second position, the torsion spring quickly releases the elastic potential energy, providing a strong lifting force for the second table 2, so that it can quickly and stably pop out of the accommodating cavity 14 to the second state.

[0075] In one possible implementation, when the second tabletop 2 is in the second state, the torsion spring remains compressed. This ensures that the second tabletop 2 is still subject to a lifting force in the second state, helping to maintain its stability and preventing it from sinking or moving due to external interference or its own weight. This increases the service life of the second tabletop 2.

[0076] See also Figure 1 and Figure 2In one possible implementation, the drive assembly 3 further includes a resilient telescopic member 33. The resilient telescopic member 33 is connected between the first tabletop 1 and the resilient lifting assembly 32. The resilient telescopic member 33 allows the resilient lifting assembly 32 and the second tabletop 2 to move from inside the receiving cavity 14 to outside the receiving cavity 14 through the opening 13. When the resilient lifting assembly 32 and the second tabletop 2 are outside the receiving cavity 14, the resilient telescopic member 33 has an elastic restoring force that applies towards the resilient lifting assembly 32, pointing inwards into the receiving cavity 14.

[0077] When it is necessary to restore the second tabletop 2 from the second state to the first state, the elastic restoring force of the elastic telescopic member 33 can assist the elastic lifting assembly 32 and the second tabletop 2 in moving into the receiving cavity 14. Thus, it is convenient for the second tabletop 2 to move into the receiving cavity 14.

[0078] Even without externally applied significant pressure, the elastic telescopic member 33 can provide a certain amount of tension to help the second table 2 retract smoothly into the receiving cavity 14, making the resetting operation of the table 10 more convenient and smooth.

[0079] The elastic telescopic component 33 restricts the movement of the elastic lifting assembly 32 and the second table 2.

[0080] See also Figure 1 and Figure 2 In one possible implementation, the elastic telescopic member 33 is a coil spring. The drive assembly 3 also includes a rotating member 34. The rotating member 34 is rotatably connected to the base 31. One end of the coil spring is wound around the rotating member 34.

[0081] The rotating component 34 provides a fixed position for the coil spring. The coil spring can store a large amount of elastic potential energy during stretching or torsion. When the second table 2 needs to be reset from the second state to the first state, the coil spring can quickly release the elastic potential energy, providing a strong reset force for the second table 2, so that the reset action is rapid and reliable.

[0082] For example, the rotating component 34 can be a rotating roller or a rotating shaft.

[0083] See also Figure 1 and Figure 2 In one possible implementation, the drive assembly 3 further includes a limiting member 35. The limiting member 35 is connected to the base 31 and has a limiting groove. The limiting groove 35 extends along the sliding direction of the second table 2. The unfolded portion of the coil spring is located in the limiting groove.

[0084] The limiting groove extends along the sliding direction of the second table plate 2, providing a guide path for the unfolding and retraction of the coil spring. In this way, the coil spring can move in a predetermined direction during operation, reducing the possibility of twisting, entanglement, or deviation during extension and retraction, thereby enabling the coil spring to stably exert its elastic effect and provide stable power for the movement of the second table plate 2.

[0085] Placing the extended portion of the coil spring within the limiting groove prevents it from colliding or rubbing against other surrounding components. The limiting groove protects the coil spring, reducing wear, scratches, or damage that may occur due to contact with other objects, extending its lifespan, and improving the reliability of the drive assembly 3.

[0086] For example, the connection methods between the limiting member 35 and the base 31 include, but are not limited to: bolt connection, snap-fit, adhesive bonding, welding, and integral molding.

[0087] In summary, when the second tabletop 2 needs to be pulled out, the user applies force to the second tabletop 2 to move it and cause the elastic telescopic component 33 to deform. During the deformation of the elastic telescopic component 33, a restoring force is generated to return the second tabletop 2 to its first state. When the second tabletop 2 switches from the first state to the second state, the elastic lifting component 32 provides a lifting force to the second tabletop 2 so that the second top surface 21 is coplanar with the first top surface 11.

[0088] When the second tabletop 2 is retracted into the receiving cavity, the user applies force to the second tabletop 2. After overcoming the lifting force applied by the user to the second tabletop 2, it moves to the first state under the action of the restoring force generated by the elastic telescopic member 33, that is, it is located in the receiving cavity 14.

[0089] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
