Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to an adaptive collapse support structure of a shoulder massage module of an automobile seat. Background Art

[0002] In today's society, cars are one of the important means of transportation for people to travel. With the improvement of people's living standards, people have higher expectations for the comfort of car interiors. Especially for passengers, maintaining the same posture for a long time during long-distance travel can easily lead to physical fatigue and discomfort.

[0003] Car seats with shoulder massage function are one of the products that ensure the riding comfort of passengers. In the prior art, although the shoulder massage seats launched on the market can massage the shoulders of passengers, most of the entire shoulder massage devices are fixedly installed and cannot meet the needs of passengers of different body shapes. Although there are a few that rotate the shoulder massage device on the seat back through a synchronization rod and control its rotation through an electric adjuster to meet the needs of passengers of different body shapes, the entire adjustment component lacks a collapse function. When the car is subjected to a backward impact force, the entire shoulder massage device cannot collapse backward in time, thereby causing a load on the shoulders of the passengers, posing a great safety hazard. Summary of the invention

[0004] In view of this, the present invention provides an adaptive collapse support structure for a shoulder massage module of an automobile seat, aiming to improve the safety of the shoulder support massage device.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows:

[0006] An adaptive collapse support structure for a shoulder massage module of an automobile seat comprises a seat back and a shoulder rest rotatably mounted at the shoulder position of the seat back, and is characterized in that an elastic element is arranged between the shoulder rest and the seat back, and the elastic element applies a thrust to cause the shoulder rest to flip forward relative to the seat back; a driving mechanism is arranged between the shoulder rest and the seat back, and the driving mechanism is used to actively control the shoulder rest to overcome the resistance of the elastic element and rotate and fold backward; when the shoulder rest is in the forward unfolded state, the thrust from the shoulder of the occupant can force the shoulder rest to overcome the resistance of the elastic element and passively rotate and fold backward.

[0007] By adopting the above structure, the shoulder rest can be placed in a folded state through the arranged driving mechanism. When the driving mechanism is running, the thrust applied by the elastic element to the shoulder rest can be released to make the shoulder rest flip forward, thereby adapting to the shoulder rest needs of occupants of different body sizes. The backward thrust of the occupant can make the shoulder rest collapse backward, thereby reducing the impact force on the occupant during a car collision, thereby ensuring the safety of the occupant.

[0008] Preferably, the shoulder rest is fixedly connected to a swing arm extending backward, the elastic element is supported between the swing arm and the seat back, and the driving mechanism can pull the shoulder rest to rotate backward through the swing arm. With the above structure, the shoulder rest can be more conveniently controlled to rotate by connecting the driving mechanism to the swing arm.

[0009] Preferably: the distal end of the swing arm is provided with a groove opening upward, the driving mechanism includes a first rotating motor fixedly arranged at the rear end of the seat back, the output end of the first rotating motor is connected to a first screw, the first screw is arranged along the height direction of the seat back, a first slider is threadedly mounted on the first screw, and the first slider has a limiting column located in the groove; when the shoulder rest is in the forward unfolded state, the thrust from the shoulder of the occupant can force the groove to move downward and separate from the limiting column. With the above structure, when the first slider moves upward along the first screw, the pressure on the elastic element can be released, thereby causing the elastic element to push the shoulder rest to rotate forward, and when the shoulder rest is in the forward unfolded state, the thrust from the shoulder of the occupant can cause the groove to actively move downward and separate from the limiting column, thereby forming a collapse.

[0010] Preferably, the elastic element is a pneumatic spring, and its two ends are respectively hinged on the swing arm and the first rotary motor. The above structure ensures that the elastic element can stably apply a force for the shoulder rest to rotate forward, and can also play a buffering role when the shoulder rest collapses, further ensuring the safety of the occupant.

[0011] As a preference: a strip hole is provided on the swing arm, the strip hole extends in the thickness direction of the seat back, the driving mechanism comprises a second rotary motor rotatably arranged at the rear end of the seat back, the output end of the second rotary motor is connected to a second screw rod, the second screw rod is arranged in the thickness direction of the seat back, a second slider is threadedly mounted on the second screw rod, and the second slider has a pin shaft arranged in the strip hole; when the shoulder rest is in the forward unfolded state, the thrust from the shoulder of the occupant can force the strip hole to move backward relative to the pin shaft. With the above structure, when the second slider moves forward along the second screw rod, the pressure applied to the elastic element can be released, so that the elastic element pushes the shoulder rest to rotate forward, and at the same time, the second rotary motor rotates backward around the rotation, and when the shoulder rest is in the forward unfolded state, the thrust of the shoulder of the occupant can cause the strip hole to move backward relative to the pin shaft, that is, the second slider is forced to move from the rightmost end of the strip hole to the leftmost end of the strip hole, thereby forming a collapse.

[0012] Preferably, the elastic element is a spring, the swing arm has a mounting protrusion extending downward, the lower end of the spring abuts against the seat back, and the upper end is always mounted on the mounting protrusion. With the above structure, the elastic element can continuously apply a forward thrust to the shoulder rest, and at the same time, it can play a buffering role when the shoulder rest collapses, further ensuring the safety of the occupant.

[0013] As a preference, a massage component is integrated inside the shoulder support. With the above structure, the shoulders of the passengers can be massaged to relieve the shoulder fatigue of the passengers.

[0014] Preferably, the driving mechanism is provided with two groups, which are symmetrically distributed on the left and right sides of the seat back and connected by a connecting plate, and the lower ends of the shoulder rest are rotatably arranged at both ends of the connecting plate. The above structure can make the shoulder rest rotate more stably.

[0015] Preferably, a lifting assembly is provided between the seat back and the shoulder rest, the lifting assembly is used to drive the shoulder rest to move up and down relative to the seat back, the lifting assembly includes a lifting motor, the lifting motor is arranged in the middle of the seat back, a third screw rod is provided at the output end of the lifting motor, the third screw rod is arranged along the length direction of the seat back, and the middle of the connecting plate is threadedly assembled with the third screw rod. With the above structure, the height adjustment of the shoulder rest can be achieved.

[0016] As a preference, the driving mechanism is arranged on the connecting plate. With the above structure, it can be ensured that the front and rear rotation and the up and down adjustment of the shoulder rest will not cause motion interference with each other.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The adaptive collapse support structure of the shoulder massage module of the automobile seat provided by the present invention can put the shoulder rest in a folded state through a driving mechanism. When the driving mechanism is running, the thrust applied by the elastic element to the shoulder rest can be released to make the shoulder rest flip forward, thereby adapting to the shoulder rest needs of occupants of different body shapes. The backward thrust of the occupant can make the shoulder rest actively collapse backward, thereby reducing the impact force on the occupant during a car collision, thereby ensuring the safety of the occupant.

[0019] 2. The lifting assembly provides height adjustment for the shoulder rest, further meeting the needs of passengers of different body shapes.

[0020] 3. Two collapse modes are set up, and each collapse mode is equipped with an elastic element, which can ensure that when the car collides, the shoulder rest can slowly rotate backwards, thereby playing a buffering role for the occupants, and at the same time can also ensure the service life of each screw rod.

[0033] The present invention is further described below in conjunction with embodiments and drawings.

[0034] like Figures 1 to 9As shown, an adaptive collapse support structure of a shoulder massage module of a car seat includes a seat back 1 and a shoulder support 2 rotatably mounted at the shoulder position of the seat back 1. In this embodiment, a massage component is integrated inside the shoulder support 2 to relieve the shoulder fatigue of the occupant. An elastic element 3 is installed between the shoulder support 2 and the seat back 1. The elastic element 3 applies a thrust to make the shoulder support 2 flip forward relative to the seat back 1. A driving mechanism A is also arranged between the shoulder support 2 and the seat back 1. The driving mechanism A is used to actively control the shoulder support 2 to overcome the resistance of the elastic element 3 and rotate and fold backward. When the shoulder support 2 is in the forward unfolded state, the thrust from the shoulder of the occupant can force the shoulder support 2 to overcome the resistance of the elastic element 3 and passively rotate and fold backward.

[0035] The driving mechanism A can keep the shoulder rest 2 in a folded state. At this time, the elastic element 3 is compressed and stores force. When the driving mechanism A is running, the thrust of the elastic element 3 on the shoulder rest 2 can be released, so that the shoulder rest 2 rotates forward to meet the needs of occupants of different body shapes for the shoulder rest 2. When the shoulder rest 2 is in a forward deployed state, the thrust of the occupant's shoulder can make the shoulder rest 2 overcome the resistance of the elastic element 3 and rotate and fold backward. It can be passively collapsed by external force. When the car is hit, the impact force on the occupant can be reduced, thereby ensuring the safety of the occupant.

[0036] In this embodiment, the shoulder rest 2 is fixedly connected to a swing arm 4 extending backward, the elastic element 3 is supported between the swing arm 4 and the seat back 1, and the driving mechanism A can pull the shoulder rest 2 to move backward through the swing arm 4.

[0037] Specifically, the present invention provides the following two different connection modes between the rotating assembly A and the swing arm 4.

[0038] Embodiment 1:

[0039] like Figures 2 to 4 As shown, a groove 4a is formed at one end of the swing arm 4 away from the shoulder rest, and the groove 4a is open and upwardly arranged. The driving mechanism A includes a first rotary motor 5 fixedly installed at the rear end of the seat back 1. The output end of the first rotary motor 5 is connected to a first screw rod 6, which is arranged along a fixed direction of the seat back 1. A first slider 7 is threadedly assembled on the first screw rod 6, and the first slider 7 has a limiting column 7a located in the groove 4a. Figure 2 and Figure 3When the shoulder rest 2 is in the folded state, the first slider 7 is located at the bottom end of the first screw rod 6, and the limit column 7a is supported in the groove 4a. When the first rotary motor 5 runs and drives the first slider 7 to move upward along the first screw rod 6, the thrust of the elastic element 3 on the shoulder rest 2 can be released, so that the shoulder rest 2 can be rotated forward to meet the needs of members of different body shapes for the shoulder rest 2. During the upward movement of the first slider 7, the limit column 7a is always in the groove 4a. When the shoulder rest 2 needs to be rotated backward and folded, the first slider 7 moves downward and presses the swing arm 4 to overcome the thrust of the elastic element 3 and move downward. Figure 4 When the shoulder rest 2 is in the forward deployed state, the thrust from the occupant's shoulder can force the groove 4a to move downward and separate from the limiting column 7a, so that the shoulder rest 2 collapses and folds backward. At the same time, during the collapse process, the first screw rod 6 is ensured not to be affected by the downward collapse force, thereby ensuring the service life of the first screw rod 6.

[0040] In this embodiment, the elastic element 3 is a pneumatic spring, and its two ends are respectively rotatably connected to the middle position of the swing arm 4 and the base of the first rotary motor 5. In this way, the elastic element 3 can stably apply an upward thrust to the swing arm 4 to ensure that the shoulder rest 2 can rotate forward. At the same time, the elastic element 3 can ensure that the shoulder rest 2 plays a buffering role when it collapses backward, further reducing the impact force on the shoulder of the occupant and ensuring the safety of the occupant.

[0041] In this embodiment, two sets of driving mechanisms A are provided, and the two sets of driving mechanisms A are symmetrically distributed on the left and right sides of the seat back 1, and the two sets of driving mechanisms A are connected by a connecting plate 11, and the two sides of the lower end of the shoulder rest 2 are rotatably mounted on both ends of the connecting plate 11. Through the design of the two sets of driving mechanisms A, the shoulder rest 2 can rotate more stably.

[0042] like Figure 1 , Fig.11 and Fig.12 As shown, a lifting assembly B is also installed between the seat back 1 and the shoulder rest 2. The lifting assembly B is used to drive the shoulder rest 2 to move up and down relative to the seat back 1. The lifting assembly B includes a lifting motor 12. In this embodiment, the lifting motor 12 is fixedly installed in the middle of the seat back 1. The output end of the lifting motor 12 is connected to a third screw rod 13. The third screw rod 13 is arranged along the length direction of the seat back 1, and the middle position of the connecting plate 11 is threadedly assembled with the third screw rod 13. With this design, the height adjustment of the shoulder rest 2 can be realized, and the needs of passengers of different body shapes for the shoulder rest 2 can be further met.

[0043] At the same time, the first rotary motor 5 is fixedly mounted on the connecting plate 13, so as to ensure that the forward and backward rotation and height adjustment of the shoulder rest 2 will not cause motion interference with each other.

[0044] Embodiment 2:

[0045] like Figures 6 to 10 As shown, a strip hole 4b is formed on the swing arm 4, and the strip hole 4b extends along the thickness direction of the seat back 1. The driving mechanism A includes a second rotary motor 8 rotatably arranged at the rear end of the seat back 1. The output end of the second rotary motor 8 is connected to a second screw rod 9, and the second screw rod 9 is arranged along the thickness direction of the seat back 1. A second slider 10 is threadedly assembled on the second screw rod 9, and the second slider 10 has a pin shaft 10a arranged in the strip hole 4b. Figure 6 and Figure 7 When the shoulder rest 2 is in the folded state, the second slider 10 is located at the rearmost end of the strip hole 4b, that is, Figure 6 At the rightmost end of the seat back 1, when the second rotary motor 8 runs and drives the second slider 10 to move forward along the second screw rod 9, the driving mechanism A releases the thrust of the elastic element 3 on the shoulder rest 2, thereby pushing the shoulder rest 2 to rotate forward to meet the needs of passengers of different body shapes for the shoulder rest 2. At the same time, the second rotary motor 8 rotates toward the rear side of the seat back 1 to ensure that no motion interference is formed. During the whole process, the second slider 10 is always located at the rearmost end of the strip hole 4b, that is, Figure 7 Locked state. Fig. 9 When the shoulder support 2 is in the forward unfolded state, the thrust from the shoulder of the occupant can force the strip hole 4b to move toward the second slider 10, that is, Fig. 9 In the state shown, the shoulder rest 2 is in a completely collapsed and folded state, the second slider 10 is located at the front end of the strip hole 4b, and the position of the second slider 10 on the second screw rod 9 remains unchanged, thereby ensuring that the drive mechanism A is not affected during the entire collapse process, thereby ensuring the service life of the second screw rod 9.

[0046] In this embodiment, the elastic element 3 is a spring and is arranged along the length direction of the seat back 1. The swing arm 4 has a downwardly extending mounting protrusion 4c. The lower end of the spring is fixed against the car seat, and the upper end is always mounted on the mounting protrusion 4c. Such a design can stably apply an upward thrust to the swing arm 4, thereby allowing the shoulder rest 2 to rotate forward. At the same time, when the shoulder rest 2 collapses backward, the elastic element 3 can further buffer the impact force on the occupant's shoulder, thereby ensuring the occupant's riding safety.

[0047] like Figure 5 As shown, in this embodiment, the driving mechanism A is also provided with two groups, and is symmetrically distributed on the left and right sides of the seat back 1. The two groups of driving mechanisms A are also connected by a connecting plate 11. The middle part of the connecting plate 11 is threadedly assembled with the third screw rod 13, so as to ensure that the shoulder rest 2 has both forward and backward rotation and height adjustment functions.

[0048] At the same time, the second rotary motor 8 and the elastic element 3 are fixedly mounted on the connecting plate 13 to ensure that there is no motion interference between the driving mechanism A and the lifting assembly B.

[0049] 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.
