Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, and more specifically to a seat installation structure that facilitates bed-like assembly and an automobile equipped with the structure. Background Technology

[0002] With rapid economic development, automobiles are playing an increasingly important role in people's daily lives, no longer just ordinary means of transportation, but needing to meet various needs of users during business trips, travel, and other activities, such as rest and work. To meet users' comfort needs during rest, seats have been given the function of transforming into beds.

[0003] In existing technologies, car seats are typically transformed into beds in two ways: one is by adjusting the backrest angle by reclining the seat back; the other is by assembling multiple seats together. Clearly, the former results in a shorter overall structure after assembly, which cannot accommodate users of different body types, while the latter is cumbersome to operate and offers poor comfort when assembled.

[0004] Therefore, how to quickly and easily transform a chair into a bed while ensuring sufficient support length is a pressing technical challenge that needs to be addressed. Summary of the Invention

[0005] In view of this, one of the objectives of the present invention is to provide a convenient seat installation structure for bed assembly, aiming to solve the technical problems of cumbersome operation and insufficient support length after bed assembly in the prior art.

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

[0007] A convenient seat installation structure for bed assembly, the key features of which are: a seat body and a traction mechanism arranged at the rear of the seat body, the seat body including a seat support assembly and a backrest assembly, the backrest assembly including a front backrest and a rear backrest rotatably connected at the upper end, the lower end of the front backrest rotatably mounted at the rear end of the seat support assembly, the lower end of the rear backrest being connected to the traction mechanism, and a support rotatably mounted at the lower end of the rear backrest, the traction mechanism being used to allow the support to be movably mounted into the interior of the vehicle;

[0008] The seat body has a sitting mode and a reclining mode. In the sitting mode, the front backrest and the backrest are arranged overlapping. The traction mechanism can move along the front-to-back direction of the seat. When the traction mechanism moves backward, it can control the front backrest and the backrest to unfold backward, so that the seat body can switch from the sitting mode to the reclining mode.

[0009] With the above structure, the traction mechanism controls the support to slide backward, which in turn drives 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, the support can pull the backrest to slide backward and rotate the backrest forward around the support while simultaneously driving the front backrest to rotate backward around the adapter until the front and backrests are completely flat, thus transforming the seat into a bed.

[0010] Preferably, the traction mechanism includes a guide rail for fixed mounting to the interior of the vehicle and a slider slidably mounted on the guide rail. The support is fixedly connected to the slider. The traction mechanism is provided with a drive assembly for driving the slider to slide back and forth.

[0011] Preferably, the upper end of the backrest assembly is provided with a first adapter component, the 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 an angle adjuster, which is used to drive the front backrest to rotate back and forth.

[0012] Preferably, the angle adjuster is located between the front backrest and the rear end of the seat support assembly. When the seat is in a sitting position, the angle adjuster drives the front backrest to rotate back and forth, which can drive the rear backrest to rotate synchronously.

[0013] Preferably, the upper end of the front backrest is provided with a first crossbar, the upper end of the rear backrest is provided with a second crossbar, and the two ends of the first adapter component in the length direction are respectively rotatably connected to the first crossbar and the second crossbar.

[0014] Preferably, a torsion spring is provided between the first adapter and the front backrest, and the torsion spring applies a force that deforms the angle between the first adapter and the front backrest.

[0015] Preferably, the number of the first adapter components is two sets.

[0016] Preferably, the upper end of the front backrest is provided with a rearwardly inclined support crossbar, and the upper end of the rear backrest is fixedly provided with a second adapter extending upwardly at an incline, the end of the second adapter away from the rear backrest being rotatably connected to the support crossbar.

[0017] Preferably, the seat support assembly has upwardly extending adapters fixed on both sides of its rear end, and the lower end of the front backrest is rotatably mounted on the two adapters.

[0018] The second objective of this invention is to provide an automobile, the key feature of which is: a seat installation structure that facilitates bed-like assembly as described above, wherein the seat body and the traction mechanism are assembled in a front-to-back relationship inside the automobile.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The convenient bed-forming seat installation structure provided by this invention allows the front and back backrests to overlap in the seated position. When the seat needs to be transformed into a bed, the traction mechanism controls the support to slide backward, which in turn moves the lower end of the backrest 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, the support can pull the backrest to slide backward and rotate the backrest forward around the support while simultaneously rotating the front backrest backward around the adapter until the front and back backrests are completely flat, thus transforming the seat into a bed. This design offers advantages such as convenient operation, suitable size, and good comfort.

[0021] 2. By installing a torsion spring between the first transition component and the front backrest, the gap between the first transition component and the front backrest can be eliminated, ensuring that the front backrest and the backrest remain tightly connected when the seat is in a sitting position, thus guaranteeing the stability of the overall structure. When the seat is returned from a reclining mode to a sitting mode, the torsion spring ensures that the connection point between the front backrest and the backrest has an upward pre-rotational force, guaranteeing the stability and reliability of the front backrest and the backrest when combined.

[0031] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0032] An automobile is provided which is equipped with a seat installation structure that facilitates the conversion into a bed. The seat installation structure will be described in detail below.

[0033] Example 1

[0034] Please refer to Figure 1 and 3 A convenient seat installation structure for bed assembly includes a seat body and a traction mechanism 4 arranged behind the seat body. The seat body and the traction mechanism 4 are assembled in a front-to-back relationship inside the vehicle. The seat body includes a seat support assembly 1 and a backrest assembly, wherein the seat support assembly 1 has upwardly extending adapters 11 fixed on both sides of its rear end. The backrest assembly includes a front backrest 2 and a rear backrest 3 rotatably connected at their upper ends. The lower ends of the front backrest 2 are rotatably mounted on the two adapters 11, and the lower ends of the rear backrest 3 are connected to the traction mechanism 4. Specifically, a support 5 is rotatably mounted on the lower end of the rear backrest 3, and the traction mechanism 4 is used to allow the support 5 to be moved back and forth within the vehicle.

[0035] The seat itself has a sitting posture mode and a reclining mode. In the sitting posture mode, refer to... Figure 3 The front backrest 2 and the rear backrest 3 are arranged overlappingly, and the traction mechanism 4 can move along the fore-and-aft direction of the seat. (Refer to...) Figure 6 and Figure 7 The traction mechanism 4 moves backward, which can control the front backrest 2 and the rear backrest 3 to unfold backward, so that the seat body can switch from sitting mode to 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, which in turn drives the lower end of the backrest 3 to move backward. Since the lower end of the 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 backrest 3, and the lower end of the front backrest 2 is rotatably connected to the rear end of the seat support assembly 1, the support 5 can pull the backrest 3 to slide backward and the backrest 3 to rotate forward around the support 5 during the process of moving the lower end of the backrest 3 backward. At the same time, it can drive the front backrest 2 to rotate backward around the adapter 11 until the front backrest 2 and the backrest 3 are completely flat, thereby realizing the transformation of the seat into a bed. It has the technical advantages of convenient operation and appropriate overall structural size, and can meet the user's support length and comfort when lying flat.

[0037] Refer to Figure 1 and 3The traction mechanism 4 includes a guide rail 41 fixedly mounted inside the vehicle and a slider 42 slidably mounted on the guide rail 41. A support 5 is fixedly connected to the slider 42. The traction mechanism 4 is provided with a drive assembly 6, which can drive the slider 42 to slide back and forth. In this embodiment, the support 5 is located at the lower middle of the backrest 3 to ensure that the force is balanced when the support 5 pulls the backrest 3.

[0038] like Figure 1 As shown, the upper end of the backrest assembly is provided with a first adapter component 8, and the two ends of the first adapter component 8 are respectively hinged to the upper ends of the front backrest 2 and the rear backrest 3. Figure 4 As can be seen, the backrest assembly is equipped with an adjuster 7, which can drive the front backrest 2 to rotate back and forth. (Reference) Figure 3 In the sitting position mode, the front backrest 2, the first connecting component 8, the rear backrest 3, and the "seat support assembly 1 and the support 5" form a four-bar linkage 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 tilt angle within a small range, and thus meeting the user's comfort needs in the sitting position.

[0039] like Figure 4 As shown, in this embodiment, the angle adjuster 7 is located between the front backrest 2 and the two adapters 11. In the seated position, the angle adjuster 7 drives the front backrest 2 to rotate back and forth, which in turn drives the rear backrest 3 to rotate synchronously. In addition, when the seat body is in the reclining mode, the angle adjuster 7 drives the front backrest 2 to rotate upward, which in turn drives the rear backrest 3 to rotate upward, and pulls the support 5 and the slider 42 to slide forward, thereby completing the transformation of the seat body from the reclining 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 crossbar 21 at its upper end, and the rear backrest 3 has a second crossbar 31 at its upper end, which are then combined with... Figure 5 As shown, the first adapter component 8 is a block structure with connecting through holes 81 at both ends along its length. The first crossbar 21 and the second crossbar 31 are rotatably connected to the two connecting through holes 81, respectively. In this embodiment, the first adapter component 8 is a split structure, consisting of upper and lower parts that are snapped together for easy assembly.

[0041] Refer to Figure 2A torsion spring a is provided between the first transition component 8 and the front backrest 2. The torsion spring a applies a force that deforms the angle between the first transition component 8 and the front backrest 2. In this way, when the seat body is in a sitting position, the torsion spring a can eliminate the gap between the first transition component 8 and the front backrest 2, ensuring that the front backrest 2 and the rear backrest 3 always remain tightly connected, thus guaranteeing the stability of the overall structure. When the seat body retracts from the reclining 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 rotational pre-push force, ensuring the stability and reliability of the combined front backrest 2 and rear backrest 3. In this embodiment, the torsion spring a is located between the first transition component 8 and the end of the first crossbar 21.

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

[0043] Example 2

[0044] The difference between this embodiment and Embodiment 1 lies in the transition structure between the upper ends of the front backrest 2 and the rear backrest 3, as detailed below:

[0045] Please refer to Figure 8 In this embodiment, the upper end of the front backrest 2 is provided with a rearwardly inclined support crossbar 22, and the upper end of the rear backrest 3 is fixedly provided with a second, upwardly extending transition component 9. The end of the second transition component 9 away from the rear backrest 3 is rotatably connected to the support crossbar 22. With this design, the traction mechanism 4 drives the support 5 to move backward, which can also control the front backrest 2 and the rear backrest 3 to unfold backward (see reference). Figure 9 ).

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention. Those skilled in the art, under the guidance of the present invention, can make various similar representations without departing from the spirit and claims of the present invention, and such modifications all fall within the protection scope of the present invention.
