Description

Technical Field

[0001] The present invention relates to the technical field of automobile seats, in particular to a multifunctional automobile seat. Background Art

[0002] Users' requirements for the riding comfort of car seats are gradually increasing, and the functions of car seats are becoming more and more abundant. For example, some car seats are equipped with zero-gravity mode, which simulates the feeling of weightlessness experienced by astronauts in space; some car seats are equipped with seat cushions that dive and backrests that fold and store, which can save space in the car; some car seats are equipped with big bed mode. When passengers need to lie down, the backrest of the car seat can be flipped back relative to the seat cushion and be on the same plane as the backrest.

[0003] Existing car seats that can achieve zero-gravity mode generally lack the ability to lower the seat cushion and fold the backrest, due to the complexity of their mechanisms. Those that can achieve both a lowered seat cushion and a foldable backrest, combined with a one-touch bed-converting function, generally lack the one-touch zero-gravity function. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a multifunctional car seat with the functions of seat cushion diving, backrest folding and storage, one-touch zero gravity and one-touch bed formation.

[0005] The present invention solves the technical problem by adopting a technical solution of providing a multifunctional car seat, wherein the car seat is configured with a zero-gravity mode, a bed mode, and a backrest folding and storage mode, and the car seat comprises:

[0006] A seat frame assembly and a backrest, wherein the backrest is rotatably arranged on the seat frame assembly; the seat frame assembly includes a base, a first connecting rod, a second connecting rod, a seat cushion configured as a third connecting rod, a fourth connecting rod and a fifth connecting rod, and the six connecting rods form a six-link mechanism; wherein,

[0007] The first link is rotatably arranged on the base and is hinged to one end of the second link, a first driving structure is connected to the first link, and the first driving structure can drive the first link to rotate; an end of the second link away from the first link is hinged to the seat cushion; the fifth link is rotatably arranged on the base and is hinged to one end of the fourth link, a second driving structure is connected to the fifth link, and the second driving structure can drive the fifth link to rotate; an end of the fourth link away from the fifth link is hinged to the seat cushion, a third driving structure is provided on the fourth link, and the third driving structure is arranged on the seat cushion;

[0008] When the car seat switches from the design position to the zero-gravity mode, the second driving structure limits the fifth link, and the third driving structure locks the relative rotation of the third link and the fourth link, so that the seat frame assembly forms a four-bar linkage;

[0009] When the car seat switches from the design position to the bed mode, the first driving structure limits the first connecting rod, and the third driving structure locks the relative rotation of the third connecting rod and the fourth connecting rod, so that the seat frame assembly forms a four-bar linkage;

[0010] When the car seat switches from the design position to the backrest folding and storage mode, the first driving structure limits the first connecting rod, and the second driving structure limits the fifth connecting rod, and the seat frame assembly forms a four-bar linkage.

[0011] Furthermore, the first connecting rod and the second connecting rod are arranged close to the front end of the seat cushion, and the fourth connecting rod and the fifth connecting rod are arranged close to the rear end of the seat cushion.

[0012] Furthermore, a second connecting rod is respectively provided on the left and right sides close to the seat cushion, and a fourth connecting rod is respectively provided on the left and right sides close to the seat cushion.

[0013] Furthermore, when the car seat switches from the design position state to the backrest folding storage mode, the third driving structure drives the fourth connecting rod, causing the fourth connecting rod to flip from back to front, and drives the second connecting rod to flip from back to front, and the seat cushion moves forward and dives downward.

[0014] Furthermore, a recliner is provided at the backrest;

[0015] After the seat cushion moves forward and dives downward, the recliner drives the backrest to flip forward, so that the backrest is folded and leans against the seat cushion.

[0016] Furthermore, when the car seat switches from the design position to the bed mode, the backrest is flipped flat from front to back, and the second driving structure drives the fifth connecting rod to lift the rear end of the seat cushion so that the seat cushion is flush with the backrest.

[0017] Furthermore, when the car seat switches from the design position state to the zero gravity mode, the backrest rotates from front to back, and the first driving structure drives the first connecting rod to lift the front end of the seat cushion.

[0018] Furthermore, the first driving structure, the second driving structure and the third driving structure are configured as screw motors or angle adjusters or gear motors.

[0019] Furthermore, the first connecting rod includes a first rod body and two first paddles, the two first paddles are respectively provided at two ends of the first rod body and are respectively hinged to the two second connecting rods, and the first rod body is rotatably provided on the base;

[0020] The fifth connecting rod includes a second rod body and two second paddles, the two second paddles are respectively arranged at both ends of the second rod body and are respectively hinged to the two fourth connecting rods, and the second rod body is rotatably arranged on the base.

[0021] Furthermore, the bottom of the car seat is provided with an electric slide rail, the base is arranged on the electric slide rail, and the electric slide rail can drive the car seat to slide forward and backward.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In the present invention, the seat frame assembly includes a base, a first link, a second link, a seat cushion, a fourth link, and a fifth link, forming a six-link mechanism. The second drive structure constrains the fifth link, and the third drive structure locks the relative rotation of the third and fourth links, forming a four-link mechanism. This allows the car seat to be switched to zero-gravity mode with a single click. The first drive structure constrains the first link, and the third drive structure locks the relative rotation of the third and fourth links, forming a four-link mechanism. This allows the car seat to be switched to bed mode with a single click. The first drive structure constrains the first link, and the second drive structure constrains the fifth link, forming a four-link mechanism. This allows the car seat to be switched to backrest folding and storage mode with a single click. This means that the car seat can simultaneously function in zero-gravity mode, bed mode, and backrest folding and storage mode, offering comprehensive functionality and a simple, ingenious overall structure.

[0024] In the present invention, when the car seat is in the bed mode, the rear end of the seat cushion is lifted, the backrest is folded back and flat, and the seat cushion and the backrest are kept flush, which can ensure the comfort of the passengers and avoid the situation of waist pressure.

[0025] In the present invention, when the car seat is in the backrest folding and storage mode, the seat cushion moves forward and dives downward, and the backrest flips forward, folds, and rests on the seat cushion, which ensures that the backrest will not interfere with the seat cushion when flipping forward, thereby ensuring that the backrest can be flipped forward and folded into place.

[0047] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] like Figures 1-13 As shown, the multifunctional car seat of this embodiment is equipped with zero-gravity mode, bed mode (i.e., king-size bed mode) and backrest folding and storage mode, and the car seat can switch between zero-gravity mode, bed mode and backrest folding and storage mode to select the mode of the car seat according to the user's actual usage needs.

[0049] The car seat of this embodiment mainly includes: a seat frame assembly 2 and a backrest 1, and the backrest 1 is rotatably arranged on the seat frame assembly 2; a recliner 10 is arranged on the backrest 1, and the recliner 10 can drive the backrest 1 to rotate back and forth relative to the seat frame assembly 2 to adjust the inclination angle of the backrest 1. Among them, the seat frame assembly 2 includes a base 20, a first connecting rod 21, a second connecting rod 22, a seat cushion 23 configured as a third connecting rod, a fourth connecting rod 24 and a fifth connecting rod 25, and the base 20, the first connecting rod 21, the second connecting rod 22, the seat cushion 23, the fourth connecting rod 24 and the fifth connecting rod 25 form a six-link mechanism, and the specific connection method of the six is: the first connecting rod 21 is rotatably arranged on the base 20 and is hinged to one end of the second connecting rod 22, the first connecting rod 21 is connected to a first driving structure 210, and the first driving structure 210 can drive the first The connecting rod 21 rotates; the end of the second connecting rod 22 away from the first connecting rod 21 is hinged to the seat cushion 23; the fifth connecting rod 25 is rotatably arranged on the base 20 and is hinged to one end of the fourth connecting rod 24, and the fifth connecting rod 25 is connected to a second driving structure 250, and the second driving structure 250 can drive the fifth connecting rod 25 to rotate; the end of the fourth connecting rod 24 away from the fifth connecting rod 25 is hinged to the seat cushion 23, and the fourth connecting rod 24 is provided with a third driving structure 240, and the third driving structure 240 is arranged on the seat cushion 23.

[0050] During actual use, when the car seat switches from the design position to the zero-gravity mode, the second drive structure 250 restrains the fifth link 25, and the third drive structure 240 locks the relative rotation of the third and fourth links 23 and 24, forming a four-bar linkage with the seat frame assembly 2. When the car seat switches from the design position to the bed mode, the first drive structure 210 restrains the first link 21, and the third drive structure 240 locks the relative rotation of the third and fourth links 23 and 24, forming a four-bar linkage with the seat frame assembly 2. When the car seat switches from the design position to the backrest folding and storage mode, the first drive structure 210 restrains the first link 21, and the second drive structure 250 restrains the fifth link 25, forming a four-bar linkage with the seat frame assembly 2. It should be noted that the design position of the car seat is the position in which a passenger normally sits upright.

[0051] In this embodiment, the seat frame assembly 2 includes a base 20, a first link 21, a second link 22, a seat cushion 23, a fourth link 24 and a fifth link 25, and the six links form a six-link mechanism. The fifth link 25 is limited by the second drive structure 250, and the third drive structure 240 locks the relative rotation of the third link 23 and the fourth link 24, so that the seat frame assembly 2 forms a four-link mechanism, which can switch the car seat to zero gravity mode with one click; the first link 21 is limited by the first drive structure 210, and the third drive structure 240 locks the relative rotation of the third link 23 and the fourth link 24, so that the seat frame assembly 2 forms a four-link mechanism, which can switch the car seat to bed mode with one click; the first link 21 is limited by the first drive structure 210, and the fifth link 25 is limited by the second drive structure 250, so that the seat frame assembly 2 forms a four-link mechanism, which can switch the car seat to backrest folding and storage mode. This car seat can simultaneously operate in zero-gravity mode, bed mode, and a foldable backrest mode. It boasts comprehensive functionality and a simple, ingenious overall structure. When the car seat switches from its designed position to any of the three modes, two of the three drive mechanisms act as locks, while the remaining one acts as a drive, ensuring structural stability.

[0052] Specifically, in this embodiment, the first connecting rod 21 and the second connecting rod 22 are arranged near the front end of the seat cushion 23 to facilitate driving the movement of the front end of the seat cushion 23. The fourth connecting rod 24 and the fifth connecting rod 25 are arranged near the rear end of the seat cushion 23 to facilitate driving the movement of the rear end of the seat cushion 23. More specifically, a second connecting rod 22 is provided on each of the left and right sides of the seat cushion 23, and the two second connecting rods 22 are symmetrically arranged. Furthermore, a fourth connecting rod 24 is provided on each of the left and right sides of the seat cushion 23, and the two fourth connecting rods 24 are symmetrically arranged. In actual use, the two symmetrically arranged second connecting rods 22 and the two symmetrically arranged fourth connecting rods 24 can ensure that the seat cushion 23 is subjected to balanced forces during movement, ensuring smooth movement and structural stability.

[0053] Combine Figures 1-9As shown, when the car seat switches from the design position to zero-gravity mode, the backrest 1 is driven by the recliner, rotating from front to back. The second drive structure 250 limits the fifth link 25, and the third drive structure 240 locks the relative rotation of the third and fourth links 23, 24, forming a four-bar linkage with the seat frame assembly 2. In this mode, since the rear end of the seat cushion 23 does not need to move, the front end of the seat cushion 23 needs to be raised. The fifth link 25 is limited and does not need to move. The second drive structure 250 locks the fifth link 25, and the third drive structure 240 locks the relative rotation of the third and fourth links 23, 24, so that the two links can now be treated as a single link. The first drive structure 210 drives the first link 21, driving the four-bar linkage formed on the seat frame in this mode, thereby raising the front end of the seat cushion 23. The lifting of the front end of the seat cushion 23 can be linked to the backrest 1, achieving one-touch zero-gravity mode adjustment. In zero-gravity mode, the feeling of weightlessness experienced by astronauts in space can be simulated. Passengers can half-recline on the car seat, making them feel close to being in a state of zero gravity, so as to relax their whole body, improve their comfort, ensure that they get enough rest, and enhance their experience.

[0054] Combine Figure 1-Figure 7 as well as Figure 10-11 As shown, when the car seat switches from the design position state to the bed mode, the first drive structure 210 limits the first link 21, and the third drive structure 240 locks the relative rotation of the third link 23 and the fourth link 24, so that the seat frame assembly 2 forms a four-bar linkage. The four-bar linkage formed by the seat frame assembly 2 in the bed mode is different from the four-bar linkage formed by the seat frame assembly 2 in the zero gravity mode. At this time, since the front end of the seat cushion 23 does not need to be raised or lowered in this mode, the rear end of the seat cushion 23 is lifted, and the first connecting rod 21 is limited and does not need to move. The first driving structure 210 can lock the first connecting rod 21, and the third driving structure 240 locks the relative rotation of the third connecting rod 23 and the fourth connecting rod 24. The two connecting rods can now be regarded as one connecting rod. The second driving structure 250 drives the fifth connecting rod 25 to lift the rear end of the seat cushion 23. The seat cushion 23 is flush with the backrest 1, and the recliner 10 drives the backrest 1 to rotate, and the backrest 1 is flattened from front to back, and the backrest 1 is set horizontally or approximately horizontally. The lifting of the front and rear ends of the seat cushion 23 and the backrest 1 can be linked to realize the one-button bed-forming function.

[0055] During actual use, when the car seat of this embodiment is in bed mode, the rear end of the seat cushion 23 is lifted, the backrest 1 is flipped back flat, and the seat cushion 23 remains flush with the backrest 1, which can ensure the comfort of the passengers and prevent the waist from being pushed up.

[0056] Combine Figure 1-Figure 7 as well as Figure 12-13 As shown, when the car seat switches from the design position to the backrest folding and storage mode, the first drive structure 210 restrains the first link 21, and the second drive structure 250 restrains the fifth link 25, forming a four-bar linkage for the seat frame assembly 2. At this time, because the seat cushion 23 needs to move from back to front and dive downward to ensure that it does not interfere with the forward tilting and folding of the backrest 1, the seat frame assembly 2 forms a four-bar linkage. Neither the first link 21 nor the fifth link 25 need to move, and the first drive structure 210 and the second drive structure 250 respectively serve to lock the first link 21 and the fifth link 25.

[0057] Specifically, when the car seat switches from the design position to the backrest folding and storage mode, the third driving structure 240 drives the fourth connecting rod 24, causing it to flip from rear to front, and also drives the second connecting rod 22 to flip from rear to front, causing the seat cushion 23 to move forward and dive downward. After the seat cushion 23 moves forward and dives downward, the recliner 10 drives the backrest 1 to flip forward, causing it to fold and rest against the seat cushion 23.

[0058] During actual use, when the car seat of this embodiment is in the folding and storage mode of the backrest 1, the seat cushion 23 moves forward and dives downward, and the backrest 1 flips forward, folds, and rests on the seat cushion 23, which can ensure that the backrest 1 will not interfere with the seat cushion 23 when flipping forward, thereby ensuring that the backrest 1 can be flipped forward and folded into place.

[0059] Among them, the first drive structure 210, the second drive structure 250, and the third drive structure 240 of this embodiment are configured as screw motors, angle adjusters, or gear motors, all of which are used to drive the corresponding connecting rods to rotate and switch between various modes. Of course, in this example, the first drive structure 210, the second drive structure 250, and the third drive structure 240 are preferably configured as screw motors, and the corresponding connecting rods are driven to rotate through the telescopic movement of the screw motors.

[0060] Furthermore, the first connecting rod 21 includes a first rod body 211 and two first paddles 212. The two first paddles 212 are respectively disposed at the ends of the first rod body 211 and are respectively hinged to the two second connecting rods 22. The two first paddles 212 are welded to the first rod body 211 as a whole. The first rod body 211 is rotatably mounted on the base 20. The first driving structure 210 drives the first rod body 211 to rotate, thereby rotating the first paddle 212. The rotation of the first paddle 212 drives the second connecting rod 22. Similarly, the fifth connecting rod 25 includes a second rod body 251 and two second paddles 252. The two second paddles 252 are respectively disposed at the ends of the second rod body 251 and are respectively hinged to the two fourth connecting rods 24. The two second paddles 252 are welded to the second rod body 251 as a whole. The second rod body 251 is rotatably mounted on the base 20. The second driving structure 250 drives the second rod body 251 to rotate, thereby causing the second paddle 252 to rotate. The rotation of the second paddle 252 can drive the fourth connecting rod 24. The fourth connecting rod 24 is also connected to the third driving structure 240, and the fourth connecting rod 24 can be directly driven by the third driving structure 240. The third driving structure 240 can be installed on the seat cushion 23.

[0061] Preferably, the bottom of the car seat of this embodiment is equipped with an electric slide rail, on which the base 20 is mounted. The electric slide rail can drive the car seat to slide forward and backward to adjust the car seat's forward and backward position within the vehicle as needed. A leg rest that can be deployed and retracted is located in front of the seat cushion 23 to support the passenger's calves and enhance passenger comfort.

[0062] In this solution, the multifunctional car seat has the functions of a seat cushion diving and backrest folding storage mode, a one-button zero gravity mode, and a one-button bed mode, and its implementation structure is simple.
