Description

Technical Field

[0001] This utility model relates to the field of passenger equipment arrangement or configuration in vehicles, and in particular to a seat table assembly, a seat, and a vehicle. Background Technology

[0002] Seat tray tables provide great convenience for vehicle occupants, allowing them to place personal items or work / entertainment devices such as laptops and tablets during journeys. Currently, there are two main ways to arrange seat tray tables: one is to install the tray table directly on the seat back, and the other is to install the tray table using a separate tray table bracket.

[0003] The advantage of mounting the table directly on the seat back is that it reduces the space occupied by the table and looks neat and beautiful. However, the horizontal position of the table will be affected by the tilt angle of the seat back. When the front passenger adjusts the seat back, items on the table may fall off.

[0004] Installing the tabletop using an independent bracket can prevent the tabletop's horizontal position from being affected by the seat back angle. For example, to address the issue of the tabletop's horizontal position being affected by the seat back angle, patent application CN118288879A, published on July 5, 2024, discloses a concealed car seat tabletop. This concealed car seat tabletop includes a connecting plate that is connected to the seat base and can swing back and forth. The tabletop can be folded up and unfolded by swinging the connecting plate back and forth.

[0005] The aforementioned concealed car seat tray table solves the problem of the tray table's horizontal position being affected by the seat back angle. However, in the bus industry, seats are commonly arranged in a 2+2 configuration (two seats are arranged side by side on each side with an aisle in the middle). Due to the cumulative deviation of tolerances during the production process, the two side-by-side tray tables may have a height difference after installation. Once this height difference occurs, the entire seat installation needs to be adjusted, or even the seat needs to be replaced. This not only leads to low seat installation efficiency but also increases seat costs. Utility Model Content

[0006] The purpose of this utility model is to provide a seat and table assembly to solve the problems of low installation efficiency and high cost caused by height differences due to accumulated tolerances in existing seat and table assemblies.

[0007] Meanwhile, the purpose of this utility model is also to provide a seat and vehicle using the above-mentioned seat and table assembly.

[0008] To solve the above problems, the seat and table assembly of this utility model adopts the following technical solution:

[0009] A seat and table assembly includes a table support and a table. The table support includes two legs for connecting to the left and right sides of the seat. The lower ends of the two legs are respectively provided with connecting seats for fixed connection with the seat. The legs and connecting seats are hinged together. A limiting structure for limiting the opening angle of the legs is provided between the legs and the connecting seats. The limiting structure includes a stop block and a stop block mating part respectively provided on the legs and the connecting seats. An adjustable support rod is installed on the stop block and / or the stop block mating part. The opening angle of the legs can be finely adjusted by extending or retracting the support rod.

[0010] Furthermore, the support rod is threadedly connected to the stop block or the stop block mating part where it is located.

[0011] Furthermore, the end of the support rod is provided with a support head for increasing its contact area with the supported member.

[0012] Furthermore, the support rod is a screw, and the support head is formed by the screw head.

[0013] Furthermore, the block or the mating part of the block where the support rod is located is provided with a countersunk groove for concealing the support head.

[0014] Furthermore, a nut is embedded in the stop block or stop block mating part that is threadedly connected to the support rod, and the support rod is threadedly connected to the stop block or stop block mating part through the nut.

[0015] Furthermore, the support leg is located outside the corresponding connecting seat in the left-right direction, and the stop is provided on the inner side of the support leg.

[0016] Furthermore, the upper ends of the two legs are connected by a crossbeam, and the table is mounted on the crossbeam.

[0017] Beneficial effects of the seat and table assembly: This utility model's seat and table assembly is an improved invention. By setting connecting seats on the legs, hinged to the legs, and using stops and stop-block mating parts to limit the swing angle of the legs through a stop-locking engagement, the height of the seats is limited. Since adjustable support rods are installed on the stops and / or stop-block mating parts, the opening angle of the legs can be finely adjusted by extending or retracting the support rods. When two side-by-side tabletops are of unequal height, the excessively tall tabletop can be lowered, or the insufficiently tall tabletop raised, by adjusting the support rods. In other words, when the tabletop height is not as expected, simply adjusting the support rods is sufficient to correct it, thus solving the problem of low installation efficiency and high cost caused by height differences due to accumulated tolerances in existing seat and tabletop assemblies.

[0018] The seat of this utility model adopts the following technical solution:

[0019] A seat, including a seat frame, wherein a seat table assembly is provided on the seat frame, the seat table assembly including a table support and a table, the table support including two legs for connecting to the left and right sides of the seat, the lower ends of the two legs respectively provided with connecting seats for fixed connection with the seat, the legs and connecting seats being hinged together, a limiting structure for limiting the opening angle of the legs being provided between the legs and the connecting seats, the limiting structure including a stop block and a stop block mating part respectively provided on the legs and the connecting seats, a support rod for adjusting the support height being installed on the stop block and / or the stop block mating part, the support rod being able to finely adjust the opening angle of the legs by extending or retracting.

[0020] Furthermore, the support rod is threadedly connected to the stop block or the stop block mating part where it is located.

[0021] Furthermore, the end of the support rod is provided with a support head for increasing its contact area with the supported member.

[0022] Furthermore, the support rod is a screw, and the support head is formed by the screw head.

[0023] Furthermore, the block or the mating part of the block where the support rod is located is provided with a countersunk groove for concealing the support head.

[0024] Furthermore, a nut is embedded in the stop block or stop block mating part that is threadedly connected to the support rod, and the support rod is threadedly connected to the stop block or stop block mating part through the nut.

[0025] Furthermore, the support leg is located outside the corresponding connecting seat in the left-right direction, and the stop is provided on the inner side of the support leg.

[0026] Furthermore, the upper ends of the two legs are connected by a crossbeam, and the table is mounted on the crossbeam.

[0027] Beneficial effects of the seat: This invention is an improved version of the existing seat. In this seat, the table assembly uses connecting seats on the legs to hinge the legs to the connecting seats. By using stops and stop-fitting parts, the swing angle of the legs is limited, thus limiting their height. Because adjustable support rods are installed on the stops and / or stop-fitting parts, the opening angle of the legs can be finely adjusted by extending or retracting the support rods. When two side-by-side tabletops are of unequal height, the excessively tall tabletop can be lowered, or the insufficiently tall tabletop can be raised, by adjusting the support rods. In other words, when the tabletop height is not as expected, simply adjusting the support rods is sufficient to correct it, thus solving the problem of low installation efficiency and high cost caused by height differences due to accumulated tolerances in existing seat table assembly components.

[0028] The vehicle of this utility model adopts the following technical solution:

[0029] A vehicle includes a seat, the seat including a seat frame, a seat table assembly provided on the seat frame, the seat table assembly including a table frame and a table, the table frame including two legs for connecting to the left and right sides of the seat, the lower ends of the two legs respectively provided with connecting seats for fixed connection with the seat, the legs and connecting seats being hinged together, a limiting structure for limiting the opening angle of the legs being provided between the legs and the connecting seats, the limiting structure including a stop block and a stop block mating part respectively provided on the legs and the connecting seats, a support rod with adjustable support height installed on the stop block and / or the stop block mating part, the support rod being able to finely adjust the opening angle of the legs by extending or retracting.

[0030] Furthermore, the support rod is threadedly connected to the stop block or the stop block mating part where it is located.

[0031] Furthermore, the end of the support rod is provided with a support head for increasing its contact area with the supported member.

[0032] Furthermore, the support rod is a screw, and the support head is formed by the screw head.

[0033] Furthermore, the block or the mating part of the block where the support rod is located is provided with a countersunk groove for concealing the support head.

[0034] Furthermore, a nut is embedded in the stop block or stop block mating part that is threadedly connected to the support rod, and the support rod is threadedly connected to the stop block or stop block mating part through the nut.

[0035] Furthermore, the support leg is located outside the corresponding connecting seat in the left-right direction, and the stop is provided on the inner side of the support leg.

[0036] Furthermore, the upper ends of the two legs are connected by a crossbeam, and the table is mounted on the crossbeam.

[0037] Beneficial effects of the vehicle: This utility model is an improved invention. In this vehicle, the seat table assembly uses a connecting seat on the outrigger to hinge the outrigger to the connecting seat. A stop and a stop-block mating part limit the swing angle of the outrigger, thereby limiting its height. Since an adjustable support rod is installed on the stop and / or stop-block mating part, the opening angle of the outrigger can be finely adjusted by extending or retracting the support rod. When two side-by-side tabletops are of unequal height, the excessively tall tabletop can be lowered, or the insufficiently tall tabletop can be raised, by adjusting the support rod. In other words, when the tabletop height is not as expected, only the support rod needs to be adjusted to correct it, thus solving the problem of low installation efficiency and high cost caused by height differences due to accumulated tolerances in existing seat tabletop assemblies.

[0048] The features and performance of this utility model will be further described in detail below with reference to specific embodiments.

[0049] like Figure 1 As shown, when the tabletop 1 of the seat table assembly is installed via an independent tabletop bracket 2, the tabletop bracket 2 can generally swing its upper end in the front-back direction. This allows the tabletop bracket 2 to be folded back to fit against the seat back 3 when the tabletop is not in use, preventing it from encroaching on the space in front of the passenger seat. When in use, the tabletop bracket 2 can be opened for the passenger to use the tabletop 1. And by... Figure 1 It is known that the swing angle α of the table support 2 directly affects the height h of the table 1. Therefore, if the swing angle of the table support 2 can be adjusted, the height of the table 1 can be adjusted. Based on the above characteristics, this utility model proposes a technical solution for a seat table assembly, a seat, and a vehicle, with the swing angle of the table support 2 as the basic concept.

[0050] Based on the above inventive concept, the specific implementation of the chair and table assembly of this utility model is as follows:

[0051] The seat table assembly includes a table support 2 and a table 1. The table support 2 is used to install and support the table 1. In use, it is connected to the seat support 4 via its lower end. The table 1 is used to carry passengers' personal belongings, which can improve the passenger's riding experience. Connecting the table support 2 to the left and right sides of the seat support 4 is an ideal solution. Therefore, the table support 2 includes two legs 201 for connecting to the left and right sides of the seat. When the seat table assembly is in a folded state, the two legs 201 can be folded to the left and right sides of the seat back 3, thereby freeing up space behind the seat back 3. To achieve a fixed connection with the seat, a connecting seat 202 is provided at the lower end of each of the two legs 201. The connecting seat 202 can be connected to the seat support 4, for example, at the connection position between the backrest frame and the seat cushion frame of the seat support 4. Therefore, in a preferred embodiment, the connecting seat 202 is provided with an arc-shaped portion, which can avoid the connection position between the backrest frame and the seat cushion frame. To enable connection with the seat bracket 4, connection holes and other structures can be provided on the connector 202, which will not be described in detail here.

[0052] Since the connecting seat 202 is fixedly connected to the seat bracket 4 during use, the support leg 201 is hinged to the connecting seat 202 to allow the support leg 201 to swing. This hinge can be achieved by inserting a hinge shaft independent of both, or by integrating a hinge shaft on one and providing a hinge hole on the other. To limit the height and position of the tabletop 1 when unfolded, as well as its position in the front-to-back direction, the swing angle of the support leg 201 should be limited. Therefore, a limiting structure for limiting the opening angle of the support leg 201 is provided between the support leg 201 and the connecting seat 202. This limiting structure includes a stop block 203 and a stop block mating part respectively disposed on the support leg 201 and the connecting seat 202. For example, in... Figure 1-9 In the embodiment shown, a stop 203 is provided on the support leg 201, and a section of the connecting seat 202 constitutes the stop engagement part. When the support leg 201 swings, the stop 203 revolves around the swing axis of the support leg 201. When a predetermined angle is reached, the stop 203 will contact the stop engagement part, thereby preventing the support leg 201 from continuing to rotate.

[0053] As analyzed above, when the support leg 201 is blocked, its angle α relative to the horizontal plane will directly affect the height h of the table after it is unfolded. Therefore, in order to achieve fine adjustment of the height of the table 1 (since the deviation of the table height is mainly due to the accumulation of errors and the deviation will not be too large, the adjustment of its height is referred to as fine adjustment here), an adjustable support rod 204 is installed on the block 203 and / or the block mating part. The support rod 204 can finely adjust the opening angle of the support leg 201 by extending or retracting.

[0054] When installing the seat and table assembly of this utility model, if the installed table 1 is too high due to accumulated errors, the support rod 204 can be retracted to reduce the angle α of the support leg 201 relative to the horizontal plane, thereby reducing the height h of the table 1 after unfolding. If the installed table 1 is too low due to accumulated errors, the support rod 204 can be extended to increase the angle α of the support leg 201 relative to the horizontal plane, thereby reducing the height h of the table 1 after unfolding.

[0055] To achieve convenient and precise adjustment of the support height of the support rod 204, in a preferred embodiment, the support rod 204 is threadedly connected to the stop block or the stop block mating part. For example, in Figure 2-9In the illustrated embodiment, the stop 203 is mounted on the support leg 201, and the support rod 204 is mounted on the stop 203. When the height of the tabletop 1 needs to be adjusted, only the support rod 204 needs to be turned for adjustment. Of course, in other embodiments, the stop 203 can also be mounted on the connecting seat 202. In this case, the support rod can still be mounted on the stop 203, or on the stop mating part. In this case, the stop mating part should be formed by the section of the support leg 201 near the connecting seat.

[0056] To prevent excessive stress concentration at the contact area between the support rod 204 and the block it supports or the block mating part, a support head is provided at the end of the support rod 204 to increase the contact area with the supported component. By providing the support head, the contact area between the support rod and the supported component can be increased, thereby dispersing contact stress and preventing damage to the contact point. Furthermore, as a further preferred embodiment, the support rod 204 is a screw, and the support head is formed by the screw head. Even further, a countersunk groove is provided on the block or the block mating part where the support rod is located to conceal the support head. The countersunk groove prevents the screw head from occupying extra space, thus increasing the adjustment range of the outrigger angle.

[0057] Since the support leg 201 is generally integrally formed by injection molding or other methods, the connecting seat 202 can also be formed by injection molding in some cases. In order to ensure its strength at the position where it mates with the support rod, a nut is embedded in the stop block or stop block mating part that is threadedly connected to the support rod. The support rod is threadedly connected to the stop block or stop block mating part through the nut.

[0058] Based on the above embodiments, as a preferred embodiment, the support leg 201 is located outside the corresponding connecting seat in the left-right direction, and the stop block 203 is provided on the inner side of the support leg 201. This allows the stop block 203 to be concealed, thereby avoiding any aesthetic issues or the possibility of it pinching or injuring people or objects.

[0059] exist Figure 4 , 5 In the embodiments shown in 6 and 7, the upper ends of the two support legs 201 are connected by a crossbeam 205, and the tabletop 1 is mounted on the crossbeam 205. In other embodiments, the two support legs 201 can be independent of each other, and in this case, they can be connected to the left and right ends of the tabletop 1 respectively.

[0060] The specific implementation method of the seat of this utility model is as follows:

[0061] like Figure 1-2As shown, the seat includes a seat support 4, on which a seat table assembly is provided. The seat table assembly is the seat table assembly of this utility model. Since the structure and usage of the seat table assembly have been described in detail above, they will not be repeated here.

[0062] The specific implementation method of the vehicle of this utility model is as follows:

[0063] The vehicle includes a seat, which is the seat of this utility model, and will not be described in detail here.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
