Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a passive collapse installation structure of a shoulder massage module. Background Art

[0002] In today's society, cars are an essential means of transportation. As living standards improve, people have higher expectations for car interior comfort. This is especially true for passengers, as maintaining the same posture for extended periods during long journeys can easily lead to fatigue and discomfort.

[0003] Car seats with shoulder massage function are one of the products that ensure the riding comfort of passengers. In the existing technology, 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 a small number of them use synchronization rods to rotate the shoulder massage device on the seat back and control its rotation through electric adjusters to meet the needs of passengers of different body shapes, the entire adjustment component lacks a collapse function. When the car is subjected to backward impact force, the entire shoulder massage device cannot collapse backward in time, thereby causing load on the shoulders of the passengers, posing a huge safety hazard. Utility Model Content

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

[0005] To achieve the above purpose, the technical solution of this utility model is as follows:

[0006] A passive collapse mounting structure for a shoulder massage module 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 provided 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 provided 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 extended state, the thrust from the occupant's shoulder 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 provided driving mechanism. When the driving mechanism is running, the thrust applied by the elastic element to the shoulder rest can be released, so that the shoulder rest can flip forward, thereby adapting to the shoulder rest needs of passengers of different body shapes. The backward thrust of the passenger can cause the shoulder rest to collapse backward, thereby reducing the impact force on the passenger during a car collision, thereby ensuring the safety of the passenger.

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

[0009] Preferably, the distal end of the swing arm is provided with a groove with an upward opening, the driving mechanism includes a first rotary motor fixedly arranged at the rear end of the seat back, the output end of the first rotary 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 assembled on the first screw, the first slider has a limiting column located in the groove; when the shoulder rest is in the forward deployed state, the thrust from the occupant's shoulder 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 deployed state, the thrust from the occupant's shoulder can cause the groove to actively move downward and separate from the limiting column, thereby causing collapse.

[0010] Preferably, the elastic element is a pneumatic spring, with its ends hinged to the swing arm and the first rotary motor, respectively. This structure ensures that the elastic element can stably exert a forward rotational force on the shoulder rest and, at the same time, acts as a buffer when the shoulder rest collapses, further ensuring occupant safety.

[0011] Preferably, the swing arm is provided with a strip-shaped hole extending along the thickness direction of the seat backrest, the drive mechanism includes a second rotary motor rotatably disposed at the rear end of the seat backrest, the output end of the second rotary motor being connected to a second screw, the second screw being arranged along the thickness direction of the seat backrest, a second slider being threadedly mounted on the second screw, the second slider having a pin disposed in the strip-shaped hole, and when the shoulder rest is in the forward deployed state, thrust from the occupant's shoulder can force the strip-shaped hole to move rearward relative to the pin. With the above structure, when the second slider moves forward along the second screw, the pressure applied to the elastic element is released, thereby causing the elastic element to push the shoulder rest forward. Simultaneously, the second rotary motor rotates rearwardly about a rotation axis. When the shoulder rest is in the forward deployed state, the thrust from the occupant's shoulder can cause the strip-shaped hole to move rearward relative to the pin, i.e., the second slider is forced to move from the rightmost end of the strip-shaped hole to the leftmost end of the strip-shaped hole, thereby causing the second slider to collapse.

[0012] Preferably, the elastic element is a spring, and the swing arm has a downwardly extending mounting protrusion. The lower end of the spring abuts the seat back, while the upper end remains encased in the mounting protrusion. This structure allows the elastic element to continuously apply a forward-rotating force to the shoulder rest, while also providing a cushioning effect when the shoulder rest collapses, further ensuring occupant safety.

[0013] Preferably, a massage component is integrated into the shoulder support. With the above structure, the shoulders of the occupant can be massaged to relieve shoulder fatigue.

[0014] Preferably, the drive mechanism is provided in two groups, 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 disposed 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, configured to drive the shoulder rest to move up and down relative to the seat back. The lifting assembly includes a lifting motor positioned in the middle of the seat back. A third screw is provided at the motor's output end, extending along the length of the seat back. The connecting plate is threadably engaged with the third screw at its middle portion. This structure enables height adjustment of the shoulder rest.

[0016] Preferably, 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 do not interfere with each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The passive collapse installation structure of the shoulder massage module provided by the present invention can put the shoulder rest in a folded state through the provided 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 passengers of different body shapes. The backward thrust of the passenger can make the shoulder rest actively collapse backward, thereby reducing the impact force on the passenger during a car collision, thereby ensuring the safety of the passenger.

[0019] 2. The lifting component 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 support 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 will be further described below with reference to the embodiments and accompanying drawings.

[0034] like Figures 1 to 9The figure shows a passively collapsible mounting structure for a shoulder massage module, comprising a seat back 1 and a shoulder rest 2 rotatably mounted on the shoulder portion of the seat back 1. In this embodiment, a massage component is integrated into the shoulder rest 2 to relieve shoulder fatigue. An elastic element 3 is mounted between the shoulder rest 2 and the seat back 1, applying a thrust that causes the shoulder rest 2 to tilt forward relative to the seat back 1. A drive mechanism A is also disposed between the shoulder rest 2 and the seat back 1. The drive mechanism A is configured to actively control the shoulder rest 2 to rotate and collapse backward, overcoming the resistance of the elastic element 3. When the shoulder rest 2 is in the forward-extended state, the thrust from the passenger's shoulder can force the shoulder rest 2 to passively rotate and collapse backward, overcoming the resistance of the elastic element 3.

[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 passengers of different body shapes for the shoulder rest 2. When the shoulder rest 2 is in the forward-expanded state, the thrust of the passenger's shoulder can make the shoulder rest 2 overcome the resistance of the elastic element 3 and rotate backward and fold. It can be passively collapsed by external force. When the car is hit, it can reduce the impact force on the passenger, thereby ensuring the safety of the passenger.

[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 methods between the rotating assembly A and the swing arm 4.

[0038] Example 1:

[0039] like Figures 2 to 4 As shown, a groove 4a is formed on the end of the swing arm 4 away from the shoulder rest, and the groove 4a is open and upwardly arranged. The drive mechanism A includes a first rotary motor 5 fixedly mounted on 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 in a fixed direction along 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 limiting 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 limiting 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-expanded state, the thrust from the occupant's shoulder can force the groove 4a to move downward and separate from the limit 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, with its ends rotatably connected to the middle of the swing arm 4 and the base of the first rotary motor 5, respectively. This ensures that the elastic element 3 steadily applies an upward thrust to the swing arm 4, enabling the shoulder rest 2 to rotate forward. Furthermore, the elastic element 3 acts as a buffer when the shoulder rest 2 collapses backward, further reducing the impact force on the occupant's shoulder and ensuring occupant safety.

[0041] In this embodiment, two sets of drive mechanisms A are provided, symmetrically distributed on the left and right sides of the seat back 1. These two sets of drive mechanisms A are connected by a connecting plate 11. The lower ends of the shoulder rest 2 are rotatably mounted on the ends of the connecting plate 11. The design of two sets of drive mechanisms A makes the rotation of the shoulder rest 2 more stable.

[0042] like Figure 1 、 Figure 11 and Figure 12 As shown, a lifting assembly B is also installed between the seat back 1 and the shoulder rest 2. Lifting assembly B is used to drive the shoulder rest 2 to move up and down relative to the seat back 1. Lifting assembly B includes a lifting motor 12. In this embodiment, lifting motor 12 is fixedly mounted in the middle of the seat back 1. The output end of lifting motor 12 is connected to a third screw 13. The third screw 13 is arranged along the length of the seat back 1 and is threadedly assembled with the third screw 13 in the middle of the connecting plate 11. This design allows the height of the shoulder rest 2 to be adjusted to further meet the needs of occupants of different body shapes.

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

[0044] Example 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 drive 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, which is arranged along the thickness direction of the seat back 1. The second screw rod 9 is threadedly assembled with a second slider 10, 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 rear end of the strip hole 4b, that is, Figure 6 At the rightmost end, 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 adapt to 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 movement 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. Figure 9 When the shoulder support 2 is in the forward deployed state, the thrust from the occupant's shoulder can force the strip hole 4b to move toward the second slider 10, that is, Figure 9 In the state shown, the shoulder rest 2 is in a completely collapsed and folded state, and the second slider 10 is located at the front end of the strip hole 4b. At the same time, the position of the second slider 10 on the second screw rod 9 does not change, so as to ensure that the driving 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 enabling the shoulder rest 2 to rotate forward. At the same time, when the shoulder rest 2 collapses backward, the elastic element 3 can further cushion the impact force on the occupant's shoulder, thereby ensuring the occupant's riding safety.

[0047] like Figure 5 As shown, in this embodiment, there are also two groups of drive mechanisms A, which are symmetrically distributed on the left and right sides of the seat back 1. The two groups of drive 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 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 both fixedly mounted on the connecting plate 13 to ensure that no motion interference occurs 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. Such changes fall within the scope of protection of the present invention.
