Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seats, and particularly relates to a seat mounting structure and a vehicle that are convenient for forming a bed. Background Art

[0002] With the rapid development of the economy, automobiles play an increasingly important role in people's daily lives. They are no longer just ordinary means of transportation, but need to meet various needs of users during business trips, travels, etc., such as rest, work, and so on. To meet the comfort requirements of users during rest, seats are given the function of transforming into beds.

[0003] In the prior art, the transformation of vehicle seats into beds is usually achieved in the following two ways: one is to adjust the backrest angle by laying the seat backrest flat backward; the other is to achieve it through the combined assembly of multiple seats. Obviously, the overall structure of the former is shorter after forming the bed and cannot meet the needs of users with different body shapes. The latter has a cumbersome operation process and poor comfort when assembled into a bed.

[0004] Therefore, how to quickly and conveniently transform the seat into a bed and ensure sufficient support length is a technical problem that needs to be solved urgently at present. Summary of the Utility Model

[0005] In view of this, one of the purposes of the present utility model is to provide a seat mounting structure that is convenient for forming a bed, aiming to solve the technical problems of cumbersome operation and insufficient support length after forming the bed in the background art.

[0006] To achieve the above purpose, the technical solution of the present utility model is as follows:

The seat body includes a seat support assembly and a backrest assembly. The backrest assembly includes a front backrest and a rear backrest that are rotatably connected at the upper end. The lower end of the front backrest is rotatably installed at the rear end of the seat support assembly. The lower end of the rear backrest is connected to the traction mechanism. A support is rotatably installed at the lower end of the rear backrest. The traction mechanism is used to movably assemble the support to the interior of the vehicle in the front-rear direction.

[0008] The seat body has a sitting posture mode and a lying posture mode. In the sitting posture mode, the front backrest and the rear backrest are arranged overlappingly. The traction mechanism can move along the front-rear direction of the seat. When the traction mechanism moves backward, it can control the front backrest and the rear backrest to spread backward, so that the seat body switches from the sitting posture mode to the lying posture mode.

[0009] With the above structure, the traction mechanism controls the support to slide backward, which is to drive the lower end of the backrest to move backward. Since the lower end of the backrest is rotatably connected to the support, the upper end of the front backrest is rotatably connected to the upper end of the backrest, and the lower end of the front backrest is rotatably connected to the rear end of the seat support assembly, during the process of the support driving the lower end of the backrest to move backward, the backrest can be pulled to slide backward and the backrest rotates forward around the support, while driving the front backrest to rotate backward around the adapter until the front backrest and the backrest are completely laid flat, thus realizing the transformation of the seat into a bed.

[0010] Preferably: The traction mechanism includes a guide rail for fixedly assembling inside the vehicle, and a slider slidably disposed on the guide rail. The support is fixedly connected to the slider. A driving assembly is provided on the traction mechanism, and the driving assembly is used to drive the slider to slide back and forth.

[0011] Preferably: A first adapter component is provided at the upper end of the backrest assembly. Two ends of the first adapter component are respectively hinged to the upper end of the front backrest and the upper end of the backrest. The backrest assembly is configured with an angle adjuster for driving the front backrest to rotate back and forth.

[0012] Preferably: The angle adjuster is disposed between the front backrest and the rear end of the seat support assembly. In the sitting posture state of the seat, when the angle adjuster drives the front backrest to rotate back and forth, the backrest can be driven to rotate synchronously.

[0013] Preferably: A first cross bar is provided at the upper end of the front backrest, and a second cross bar is provided at the upper end of the backrest. Two ends in the length direction of the first adapter component are respectively rotatably connected to the first cross bar and the second cross bar.

[0014] Preferably: A torsion spring is provided between the first adapter component and the front backrest, and the torsion spring applies a force to deform the included angle between the first adapter component and the front backrest.

[0015] Preferably: The number of the first adapter components is two groups.

[0016] Preferably: A support cross bar inclined backward is provided at the upper end of the front backrest, and a second adapter component extending obliquely upward is fixedly provided at the upper end of the backrest. One end of the second adapter component away from the backrest is rotatably connected to the support cross bar.

[0017] Preferably: Adapter pieces extending upward are fixedly provided on both sides of the rear end of the seat support assembly, and the lower end of the front backrest is rotatably installed on the two adapter pieces.

[0018] The second object of the present utility model is to provide a vehicle, which is characterized in that: it includes the above-mentioned seat installation structure convenient for forming a bed, and the seat body and the traction mechanism are assembled inside the vehicle in a front-rear relationship.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. By adopting the seat installation structure provided by the present utility model that is convenient for forming a bed, when the seat is in the sitting posture mode, the front backrest and the rear backrest are overlapped. When it is necessary to deform the seat into a bed, the traction mechanism controls the support to slide backward, that is, drives the lower end of the rear backrest to move backward. Since the lower end of the rear backrest is rotatably connected to the support, the upper end of the front backrest is rotatably connected to the upper end of the rear backrest, and the lower end of the front backrest is rotatably connected to the rear end of the seat support assembly, therefore, during the process of the support driving the lower end of the rear backrest to move backward, it can traction the rear backrest to slide backward and the rear backrest rotates forward around the support, and at the same time drives the front backrest to rotate backward around the adapter until the front backrest and the rear backrest are completely flattened, thus realizing the deformation of the seat into a bed, which has the advantages of convenient operation, appropriate size and good comfort.

[0021] 2. By arranging a torsion spring between the first adapter component and the front backrest, the gap between the first adapter component and the front backrest can be eliminated to ensure that when the seat is in the sitting posture state, the front backrest and the rear backrest always remain tightly connected, ensuring the stability of the overall structure. When the seat is retracted from the lying flat mode to the sitting posture mode, the torsion spring can ensure that the connection position between the front backrest and the rear backrest has a pre-thrust force for upward rotation, ensuring the stability and reliability of the combination of the front backrest and the rear backrest.

[0031] The present utility model will be further described below in conjunction with embodiments and the accompanying drawings.

[0032] An automobile is internally equipped with a seat mounting structure that is convenient for forming a bed, and the seat mounting structure will be described in detail below.

[0033] Embodiment 1

[0034] Please refer to Figure 1 and 3 , a seat mounting structure convenient for forming a bed, which includes a seat body and a traction mechanism 4 arranged behind the seat body. The seat body and the traction mechanism 4 are assembled inside the automobile in a front-back relationship. The seat body includes a seat support assembly 1 and a backrest assembly. Specifically, transfer members 11 extending upward are fixedly provided on both sides of the rear end of the seat support assembly 1. The backrest assembly includes a front backrest 2 and a rear backrest 3 that are rotatably connected at the upper end. The lower end of the front backrest 2 is rotatably installed on the two transfer members 11, and the lower end of the rear backrest 3 is connected to the traction mechanism 4. Specifically, a support 5 is rotatably installed at the lower end of the rear backrest 3, and the traction mechanism 4 is used to movably assemble the support 5 back and forth inside the automobile.

[0035] The seat body has a sitting posture mode and a lying posture mode. In the sitting posture mode, referring to Figure 3 , the front backrest 2 and the rear backrest 3 are arranged overlappingly, and the traction mechanism 4 can move along the front-back direction of the seat. Referring again to Figure 6 and Figure 7 . When the traction mechanism 4 moves backward, it can control the front backrest 2 and the rear backrest 3 to spread backward, so that the seat body is switched from the sitting posture mode to the lying posture mode.

[0036] Based on the above structural design, when it is necessary to deform the seat body into a bed, the seat support assembly 1 remains fixed, and the traction mechanism 4 controls the support 5 to slide backward, that is, drives the lower end of the rear backrest 3 to move backward. Since the lower end of the rear backrest 3 is rotatably connected to the support 5, the upper end of the front backrest 2 is rotatably connected to the upper end of the rear backrest 3, and the lower end of the front backrest 2 is rotatably connected to the rear end of the seat support assembly 1. Therefore, during the process of the support 5 driving the lower end of the rear backrest 3 to move backward, it can traction the rear backrest 3 to slide backward and the rear backrest 3 rotates forward around the support 5, and at the same time drives the front backrest 2 to rotate backward around the transfer member 11 until the front backrest 2 and the rear backrest 3 are completely laid flat, thereby realizing the transformation of the seat into a bed, which has the technical advantages of convenient operation and appropriate overall structure size, and can meet the support length and comfort for the user to lie flat.

[0037] Refer to again Figure 1 and 3, the traction mechanism 4 includes a guide rail 41 fixedly assembled inside the vehicle, and a slider 42 slidably disposed on the guide rail 41. A support 5 is fixedly connected to the slider 42. A driving assembly 6 is provided on the traction mechanism 4, and the driving assembly 6 can drive the slider 42 to slide back and forth. In this embodiment, the support 5 is disposed at the middle of the lower end of the backrest 3 to ensure that the support 5 can receive balanced forces when pulling the backrest 3 to move.

[0038] As Figure 1 shown, a first adapter component 8 is provided at the upper end of the backrest assembly. Both ends of the first adapter component 8 are respectively hinged to the upper end of the front backrest 2 and the upper end of the backrest 3. From Figure 4 it can be seen that the backrest assembly is configured with an angle adjuster 7, and the angle adjuster 7 can drive the front backrest 2 to rotate back and forth. Referring to Figure 3 , in the sitting posture mode, the front backrest 2, the first adapter component 8, the backrest 3, and the "overall composed of the seat support assembly 1 and the support 5" form a four-bar linkage structure. Driving the front backrest 2 to rotate can drive the backrest 3 to rotate synchronously, so as to achieve the purpose of adjusting the backrest inclination angle in a small range, and further meet the comfort requirements of users in the sitting posture state.

[0039] As Figure 4 shown, in this embodiment, the angle adjuster 7 is disposed between the front backrest 2 and the two adapter parts 11. In the sitting posture state of the seat, the angle adjuster 7 drives the front backrest 2 to rotate back and forth, and can drive the backrest 3 to rotate synchronously. In addition, when the seat body is in the lying flat mode, the angle adjuster 7 drives the front backrest 2 to rotate upward, which can drive the backrest 3 to rotate upward and pull the support 5 and the slider 42 to slide forward, thereby completing the conversion of the seat body from the lying flat mode to the sitting posture mode, and further improving the operation convenience.

[0040] Please refer to Figure 1 and 2 , a first cross bar 21 is provided at the upper end of the front backrest 2, and a second cross bar 31 is provided at the upper end of the backrest 3. Combining with Figure 5 shown, the first adapter component 8 is a block structure, and connection through holes 81 are provided at both ends in the length direction thereof. The first cross bar 21 and the second cross bar 31 are respectively rotatably connected to the two connection through holes 81. In this embodiment, the first adapter component 8 is a split structure, which is formed by buckling the upper and lower parts together for easy assembly.

[0041] Refer to Figure 2, a torsion spring a is provided between the first adapter member 8 and the front backrest 2, and a force is applied to the torsion spring a to deform the included angle between the first adapter member 8 and the front backrest 2. Considering this, in the sitting posture mode of the seat body, the torsion spring a can eliminate the gap between the first adapter member 8 and the front backrest 2, ensuring that the front backrest 2 and the rear backrest 3 are always tightly connected, and guaranteeing the stability of the overall structure. When the seat body is retracted from the lying flat mode to the sitting posture mode, the torsion spring a can ensure that the connection position between the front backrest 2 and the rear backrest 3 has an upward rotational pre-thrust, guaranteeing the stability and reliability of the combination of the front backrest 2 and the rear backrest 3. In this embodiment, the torsion spring a is located between the first adapter member 8 and the end of the first cross bar 21.

[0042] As Figure 1 shown, to improve the reliability of the rotational connection between the front backrest 2 and the rear backrest 3, in this embodiment, two sets of the first adapter members 8 are provided. The two sets of the first adapter members 8 are distributed along the width direction of the backrest assembly. At the same time, two sets of the torsion springs a are also provided, and the two sets of the torsion springs a are respectively arranged at both ends of the first cross bar 21.

[0043] Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 lies in the adapter structure between the upper ends of the front backrest 2 and the rear backrest 3, which is specifically as follows:

[0045] Please refer Figure 8 , in this embodiment, a support cross bar 22 inclined backward is provided at the upper end of the front backrest 2, and a second adapter member 9 extending obliquely upward is fixedly provided at the upper end of the rear backrest 3. The end of the second adapter member 9 away from the rear backrest 3 is rotatably connected to the support cross bar 22. With such a design, when the traction mechanism 4 drives the support 5 to move backward, the front backrest 2 and the rear backrest 3 can also be controlled to spread backward (refer to Figure 9 ).

[0046] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Those of ordinary skill in the art, under the inspiration of the present invention and without departing from the purpose and claims of the present invention, can make various similar representations, and such transformations all fall within the protection scope of the present invention.
