Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a seat installation structure which is convenient for forming a bed and an automobile with the structure. Background Art

[0002] With the rapid development of the economy, cars play an increasingly important role in people's daily lives. They are no longer just an ordinary means of transportation, but need to be able to meet the many needs of users during business trips, travel, etc., such as rest, work, etc. In order to meet the user's comfort needs during rest, the seat is given the function of transforming into a bed.

[0003] In the prior art, the transformation of a car seat into a bed is usually achieved in the following two ways: one is to adjust the backrest angle by laying the seat back flat; the other is to assemble multiple seats. Obviously, the former has a short overall structure after the bed is formed, which cannot meet the needs of users of different body shapes, and the latter has a cumbersome operation process and poor comfort when assembled into a bed.

[0004] Therefore, how to realize the rapid and convenient transformation of a seat into a bed while ensuring sufficient support length is a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of this, one of the purposes of the present invention is to provide a seat installation structure that is convenient for making a bed, aiming to solve the technical problems in the background technology of complicated operation and insufficient support length after the bed is made.

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

[0007] A seat installation structure that is convenient for forming a bed, the key of which is: comprising a seat body and a traction mechanism arranged at the rear of the seat body, the seat body comprising a seat support assembly and a backrest assembly, the backrest assembly comprising a front backrest and a rear backrest rotatably connected at the upper end, the lower end of the front backrest being rotatably mounted at the rear end of the seat support assembly, the lower end of the rear backrest being connected to the traction mechanism, a support being rotatably mounted at the lower end of the rear backrest, the traction mechanism being used to enable the support to be assembled to the interior of the car in a manner that it can move forward and backward;

[0008] The seat body has a sitting mode and a lying mode. In the sitting mode, the front backrest and the rear backrest are arranged overlappingly; the traction mechanism can move along the front and rear directions 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 can be switched from the sitting mode to the lying mode.

[0009] With the above structure, the traction mechanism controls the support to slide backward, that is, it drives the lower end of the rear backrest to move backward. Since the lower end of the rear backrest is rotationally connected to the support, the upper end of the front backrest is rotationally connected to the upper end of the rear backrest, and the lower end of the front backrest is rotationally connected to the rear end of the seat support assembly, the support drives the lower end of the rear backrest to move backward. Therefore, in the process of the rear backrest being pulled to slide backward and the rear backrest being rotated forward around the support, the front backrest is driven to rotate backward around the adapter until the front backrest and the rear backrest are completely flat, thereby realizing the transformation of the seat into a bed.

[0010] Preferably, the traction mechanism comprises a guide rail for fixedly assembling to the interior of the vehicle, and a slider slidably arranged on the guide rail, the support is fixedly connected to the slider, and the traction mechanism is provided with a driving assembly, and the driving assembly is used to drive the slider to slide forward and backward.

[0011] Preferably, a first adapter component is provided at the upper end of the backrest assembly, and two ends of the first adapter component are respectively hinged to the upper end of the front backrest and the upper end of the rear backrest, and the backrest assembly is equipped with a recliner for driving the front backrest to rotate forward and backward.

[0012] Preferably, the recliner is disposed between the front backrest and the rear end of the seat support assembly, and in a seat sitting position, the recliner drives the front backrest to rotate forward and backward, and can drive the rear backrest to rotate synchronously.

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

[0014] Preferably, a torsion spring is provided between the first adapter component and the front backrest, and the torsion spring applies a force that deforms the 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 supporting cross bar tilted backwards is provided at the upper end of the front backrest, a second adapter component tilted upwards is fixedly provided at the upper end of the rear backrest, and an end of the second adapter component away from the rear backrest is rotatably connected to the supporting cross bar.

[0017] Preferably, both sides of the rear end of the seat support assembly are fixedly provided with adapters extending upward, and the lower end of the front backrest is rotatably mounted on the two adapters.

[0018] The second object of the present invention is to provide an automobile, the key of which is that it includes the above-mentioned seat installation structure that is convenient for forming a bed, and the seat body and the traction mechanism are assembled inside the automobile in a front-to-back relationship.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The seat installation structure that is convenient for transforming into a bed provided by the present invention is adopted. When the seat is in the sitting mode, the front backrest and the rear backrest are arranged overlappingly. When the seat needs to be transformed 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, the support drives the lower end of the rear backrest to move backward, which can pull the rear backrest to slide backward and rotate forward around the support, while driving the front backrest to rotate backward around the adapter until the front backrest and the rear backrest are completely flat, thereby realizing the seat transformation into a bed, which has the advantages of easy operation, suitable 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 the front backrest and the rear backrest are always tightly connected when the seat is in the sitting position, thereby ensuring the stability of the overall structure. When the seat is retracted from the lying mode to the sitting mode, the torsion spring can ensure that the connection position of the front backrest and the rear backrest has an upward rotation pre-thrust force, thereby ensuring the stability and reliability of the combination of the front backrest and the rear backrest.

[0031] The present invention is further described below in conjunction with embodiments and drawings.

[0032] A car is provided with a seat installation structure which is convenient for forming a bed. The seat installation structure will be described in detail below.

[0033] Embodiment 1

[0034] Please refer to Figure 1 and 3 A seat installation structure that is convenient for forming a bed, comprising a seat body and a traction mechanism 4 arranged at the rear of the seat body, wherein the seat body and the traction mechanism 4 are assembled inside the car in a front-to-back relationship. The seat body comprises a seat support assembly 1 and a backrest assembly, wherein adapters 11 extending upward are fixedly provided on both sides of the rear end of the seat support assembly 1. The backrest assembly comprises a front backrest 2 and a rear backrest 3 that are rotatably connected at the upper ends, wherein the lower end of the front backrest 2 is rotatably mounted on two adapters 11, and the lower end of the rear backrest 3 is connected to the traction mechanism 4. Specifically, a support 5 is rotatably mounted at the lower end of the rear backrest 3, and the traction mechanism 4 is used to enable the support 5 to be assembled to the interior of the car so as to be movable forward and backward.

[0035] The seat body has a sitting mode and a lying mode. In the sitting mode, refer to Figure 3 , the front backrest 2 and the rear backrest 3 are arranged in an overlapping manner, and the traction mechanism 4 can move along the front and rear direction of the seat. Figure 6 and Figure 7 , the traction mechanism 4 moves backward, which can control the front backrest 2 and the rear backrest 3 to spread backward, so that the seat body is switched from the sitting mode to the lying mode.

[0036] Based on the above structural design, when the seat body needs to be transformed 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, in the process of the support 5 driving the lower end of the rear backrest 3 to move backward, it can pull the rear backrest 3 to slide backward and the rear backrest 3 to rotate forward around the support 5, and at the same time drive the front backrest 2 to rotate backward around the adapter 11 until the front backrest 2 and the rear backrest 3 are completely flat, thereby realizing the transformation of the seat into a bed, which has the technical advantages of easy operation and suitable overall structural size, and can meet the support length and comfort of users lying flat.

[0037] Refer to Figure 1 and 3The traction mechanism 4 includes a guide rail 41 fixedly assembled to the interior of the vehicle, and a slider 42 slidably arranged on the guide rail 41. The support 5 is fixedly connected to the slider 42. The traction mechanism 4 is provided with a driving assembly 6, which can drive the slider 42 to slide forward and backward. In this embodiment, the support 5 is arranged at the middle of the lower end of the rear backrest 3 to ensure that the support 5 can be balanced when pulling the rear backrest 3 to move.

[0038] like Figure 1 As shown, the upper end of the backrest assembly is provided with a first transfer component 8, and the two ends of the first transfer component 8 are respectively hinged to the upper end of the front backrest 2 and the upper end of the rear backrest 3. Figure 4 It can be seen that the backrest assembly is equipped with a recliner 7, which can drive the front backrest 2 to rotate forward and backward. Figure 3 In the sitting mode, the front backrest 2, the first adapter component 8, the rear backrest 3 and the "integration of the seat support assembly 1 and the support 5" form a four-bar structure, which drives the front backrest 2 to rotate and can drive the rear backrest 3 to rotate synchronously, thereby achieving the purpose of adjusting the backrest inclination angle in a small range, thereby meeting the user's comfort needs in the sitting state.

[0039] like Figure 4 As shown, in this embodiment, the recliner 7 is arranged between the front backrest 2 and the two adapters 11. When the seat is in the sitting position, the recliner 7 drives the front backrest 2 to rotate forward and backward, which can drive the rear backrest 3 to rotate synchronously. In addition, when the seat body is in the lying mode, the recliner 7 drives the front backrest 2 to rotate upward, which can drive the rear backrest 3 to rotate upward, and pull the support 5 and the slider 42 to slide forward, thereby completing the transformation of the seat body from the lying mode to the sitting mode, further improving the convenience of operation.

[0040] Please refer to Figure 1 and 2 The front backrest 2 has a first cross bar 21 at the upper end, and the rear backrest 3 has a second cross bar 31 at the upper end. Figure 5 As shown, the first adapter component 8 is a block structure, and both ends of the length direction thereof are provided with connecting through holes 81, and the first cross bar 21 and the second cross bar 31 are respectively rotatably connected to the two connecting 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 for easy assembly.

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

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

[0043] Embodiment 2

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

[0045] Please refer to Figure 8 In this embodiment, a support cross bar 22 tilted backward is provided at the upper end of the front backrest 2, and a second transfer component 9 tilted upward and extending is fixed at the upper end of the rear backrest 3. The end of the second transfer component 9 away from the rear backrest 3 is rotatably connected to the support cross bar 22. With this design, the traction mechanism 4 drives the support 5 to move backward, and can also control the front backrest 2 and the rear backrest 3 to spread backward (refer to Fig. 9 ).

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
