Description
Technical Field
[0001] This application relates to the field of automotive seat technology, and more particularly to a zero-gravity seat adjustment mechanism. Background Technology
[0002] With the improvement of living standards, cars have gradually become a means of daily transportation, which has also driven the development of the auto parts industry. As an indispensable part of a car, car seats are now subject to higher quality requirements for comfort as people pursue a higher quality of life.
[0003] The patent with publication number CN210680483U describes a car seat, which includes a bracket with a seat plastic component connected to it. The seat plastic component is connected to a backrest cushion and a seat cushion, allowing passengers to lean against the backrest cushion while riding in the car.
[0004] Regarding the aforementioned patents, the inventors discovered that most existing car seats have a simple structure and a small range of adjustment, making it difficult to provide passengers with a comfortable riding experience. They also cannot counteract the discomfort caused by gravity, and prolonged sitting can damage the lumbar spine. Therefore, improvements are needed. Summary of the Invention
[0005] To improve the comfort of car seats, this application provides a zero-gravity seat adjustment mechanism.
[0006] The zero-gravity seat adjustment mechanism provided in this application adopts the following technical solution:
[0007] A zero-gravity seat adjustment mechanism includes a support plate and a seat body. The support plate includes a horizontal plate and an inclined plate connected to each other. A rotating bracket for mounting the seat body is provided on the surface of the horizontal plate. A driving component for driving the seat body to rotate is provided on the rotating bracket. An adjustment tube is connected to the side of the seat body facing the inclined plate. An adjustment rod is slidably connected inside the adjustment tube. An adjustment groove is opened on the side of the inclined plate facing the adjustment rod for the adjustment rod to abut and slide. The adjustment rod is hollow inside. A reset component for driving the adjustment rod and the adjustment tube to reset is provided inside the adjustment rod.
[0008] By adopting the above technical solution, when a person sits on the seat body, the driving component can drive the seat body to rotate, thereby concentrating the occupant's center of gravity on their buttocks, so that other parts of the body are not under pressure, thus keeping the human body in a weightless state and evenly distributing the body pressure, thereby effectively improving the occupant's riding comfort and riding experience, and benefiting the occupant's health; after the seat body is adjusted, the reset component can be used to reset the seat body, thereby maintaining the stability of the seat body's working performance.
[0009] Preferably, the reset component includes a mounting plate, a reset sleeve, a sliding rod, a fixing rod, a reset cable, a reset motor, and a winding wheel. The mounting plate is connected to the side of the seat body facing the inclined plate. One end of the reset sleeve is connected to the mounting plate, and the other end of the reset sleeve is inserted into the adjusting tube. The sliding rod is slidably connected to the inner wall of the reset sleeve, and the end of the sliding rod facing away from the reset sleeve is connected to the inner wall of the adjusting rod. The fixing rod is connected to the end wall of the reset sleeve inserted into the adjusting tube. Both the sliding rod and the fixing rod are hollow rods. The reset cable includes a cable and terminals connected to both ends of the cable. The outer wall of the sliding rod has two locking holes for the terminals to engage, and the locking holes are connected to the hollow part of the inner wall of the sliding rod. The reset motor is connected to the side of the mounting plate opposite to the reset sleeve. The winding wheel is sleeved on the outer wall of the output shaft of the reset motor. The mounting plate has a reset hole through which the reset cable passes along its thickness direction. The cable of the reset cable passes through the sliding rod, the reset sleeve, the winding wheel, the reset hole, and the fixing rod in sequence and is connected to the corresponding terminal.
[0010] By adopting the above technical solution, when the driving component is activated, the seat body will rotate, and the adjusting rod will be inserted into the adjusting tube. At this time, the reset motor of the reset component will rotate in the forward direction, thereby pulling the reset cable and pulling the sliding rod into the reset sleeve. This allows the adjusting rod to be smoothly inserted into the adjusting tube, and also allows the end of the adjusting rod inserted into the adjusting groove to slide along the length of the adjusting groove, thereby assisting the rotation of the seat body. When the seat body needs to be reset, the reset motor will rotate in the reverse direction, thereby moving the sliding rod out of the reset sleeve through the reset cable. The sliding rod can then drive the adjusting rod to disengage from the adjusting tube, ensuring that one end of the adjusting rod always rests against the inside of the adjusting groove. This effectively improves the stability of the seat body under the adjustment of the driving component and reduces the probability of the adjusting rod falling out of the adjusting groove, thereby improving the safety and convenience of this application.
[0011] Preferably, a buffer pad is provided on the end wall of the reset sleeve inserted into the adjusting tube, one end of the sliding rod passes through the buffer pad and is inserted into the inner wall of the reset sleeve, and a limit piece is provided on the end wall of the sliding rod away from the reset sleeve. The limit piece is connected to the inner wall of the adjusting rod, and the limit piece can abut against the buffer pad after sliding. A guide wheel is rotatably connected to the end of the fixed rod away from the reset sleeve. The guide wheel is used to reduce the wear between the cable and the inner wall of the fixed rod.
[0012] By adopting the above technical solution, the buffer pad can effectively improve the problem of excessive movement of the sliding rod, which causes the sliding rod to be completely inserted into the reset sleeve and unable to fall out. At the same time, the buffer pad can withstand the impact of the limiting plate, effectively protecting the safety of the reset component structure. The guide wheel can guide the cable, making the movement of the reset cable more stable, ensuring the normal operation of the reset component, while reducing the friction between the reset cable and the inner wall of the fixed rod, protecting the safety of the reset cable structure and extending its service life.
[0013] Preferably, the rotating bracket includes a horizontal plate and vertical plates connected to both ends of the horizontal plate, and the seat body is disposed between the two vertical plates; the driving component includes a drive motor, a driving gear, a driven gear, two rotating plates, and several limiting wheels, with the rotating plates and vertical plates corresponding to each other; the surface of the horizontal plate has a driving cavity for mounting the drive motor, the driving gear is connected to the output shaft of the drive motor, the driven gear is connected to the bottom wall of the seat body, the driven gear meshes with the driving gear and can drive the seat body to rotate, the rotating plate is connected to the side wall of the seat body, and the side of the rotating plate facing the corresponding vertical plate has an arc-shaped driving groove, the length direction of the driving groove is consistent with the rotation direction of the seat body, one end of the limiting wheel is connected to the inner wall of the vertical plate, and the other end of the limiting wheel is inserted into the driving groove and abuts against the inner wall of the driving groove.
[0014] By adopting the above technical solution, when the seat body needs to be rotated and adjusted, only the drive motor needs to be started. The output shaft of the drive motor will drive the active gear to rotate, thereby driving the seat body to rotate through the meshing relationship between the active gear and the driven gear. This allows the seat body of this application to be converted into a zero-gravity mode. During the rotation of the seat body, the rotating plate will rotate with the seat body, thereby causing the drive groove to rotate. Since one end of the limit wheel is inserted into the drive groove, the probability of the seat body falling directly off the rotating bracket can be effectively reduced, resulting in high safety performance. The drive component of this application has a simple structure, a high degree of automation, and can drive the seat body to be adjusted quickly and simulate a zero-gravity state, which has high convenience and practicality.
[0015] Preferably, the driving component further includes a connecting rod and rotating bearings sleeved on the outer walls of both ends of the connecting rod. The driving gear is sleeved on the outer wall of the connecting rod. One end of the connecting rod is connected to the output shaft of the driving motor, and the other end of the connecting rod is inserted into the inner wall of the driving cavity. One of the rotating bearings is embedded in the inner wall of the driving cavity and fixedly connected to the inner wall of the driving cavity through its outer ring. The other rotating bearing is disposed between the driving motor and the driving gear.
[0016] By adopting the above technical solution, the connecting rod can improve the stability of the active gear during rotation. The connecting rod forms a rotatable connection with the cross plate through the rotating bearing, which can better bear the weight of the seat body and the passenger, effectively protecting the structural integrity of the output shaft of the drive motor. At the same time, the rotating bearing can also effectively reduce the wear between the drive component and the rotating bracket during operation, thereby enabling the drive component to operate normally. This improves the safety and stability of this application and extends the service life of the zero-gravity seat of this application.
[0017] Preferably, the inclined plate has a plurality of ventilation holes extending through it along the thickness direction. The ventilation holes can be used to circulate air from the air conditioning system inside the vehicle. The plurality of ventilation holes are located on both sides of the length direction of the adjustment groove.
[0018] By adopting the above technical solution, ventilation holes are opened and connected to the air conditioning inside the car, so that after the seat body is adjusted to a zero-gravity state, the seat body can have a ventilation function, which can further improve the riding comfort of this application and improve the riding experience of passengers.
[0019] Preferably, the side of the inclined plate opposite to the seat body is provided with a plurality of driven plates, and the plurality of driven plates abut against the outer wall of the inclined plate; a connecting rod is provided between adjacent driven plates; a driven groove is opened in the inner wall of the adjusting groove; a driving rod is provided on the outer wall of the end of the adjusting rod inserted into the adjusting groove; the end of the driving rod opposite to the adjusting rod is connected to the side wall of the adjacent driven plate; a flow hole is opened through the driven plate along the thickness direction; after the driven plate slides, the flow hole can communicate with the corresponding vent hole.
[0020] By adopting the above technical solution, a driven plate is set and a flow hole is opened on the driven plate, so that when the seat body is adjusted in zero gravity, the driven plate can be slid by adjusting the adjustment rod. Thus, when the seat body is adjusted to the position, the flow hole can be aligned with the ventilation hole, thereby enabling this application to have higher automation and convenience.
[0021] Preferably, two sliding blocks are provided between two adjacent driven plates. The sliding blocks are sleeved on the outer wall of the connecting rod and can slide along the length of the connecting rod. A miniature cylinder is provided on the side wall of each of the two adjacent driven plates that are close to each other. The piston rod of the miniature cylinder is connected to the side wall of the corresponding sliding block. Two rotating rods are rotatably connected to the surface of each sliding block. The flow hole is located between the two rotating rods. An arc-shaped groove is opened on the side of the driven plate away from the inclined plate. The arc-shaped groove is opened along the circumferential direction of the flow hole. A rotating rod is provided at the end of the rotating rod away from the corresponding sliding block. One end of the rotating rod is inserted into the arc-shaped groove and can slide along the length of the arc-shaped groove. An opening and closing plate is sleeved on the outer wall of the rotating rod. The end of the opening and closing plate away from the rotating rod is rotatably connected to the surface of the driven plate. After the two opening and closing plates are rotated, they can cover the opening of the flow hole.
[0022] By adopting the above technical solution, a micro cylinder is activated, and the piston rod of the micro cylinder drives the sliding block to slide along the length of the connecting rod. During the sliding process of the sliding block, the rotating rod will rotate, causing the rotating rod at the other end of the rotating rod to slide along the length of the arc groove, thereby driving the opening and closing plate to rotate. Thus, the size of the flow hole opening can be controlled by the rotation angle of the two opening and closing plates, which can flexibly adjust the air conditioning force inside the car. This allows passengers in the car to flexibly adjust the airflow according to their own situation, thereby further improving the riding comfort of the zero-gravity seat of this application.
[0023] Preferably, the driven plate has a sealing groove on the side facing the inclined plate, and the bottom wall of the sealing groove is provided with a plurality of compression springs. The end of the compression spring away from the bottom wall of the sealing groove is connected to a sealing clip, which can be inserted into the corresponding vent hole. All the sealing clips are hemispherical.
[0024] By adopting the above technical solution, the sealing clip can seal and protect the vent when the vent and the flow hole are not aligned, reducing the probability of foreign objects entering the vent and causing blockage, and has high practicality.
[0025] Preferably, the sidewall of the support plate is provided with a protective plate to improve the safety of the seat body.
[0026] By adopting the above technical solution, the protective plate can effectively protect the occupants on the seat body, thereby reducing the probability that the occupants will fall off the seat body when it is being adjusted, thus effectively improving the safety of this application.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. This application enables the seat body to rotate at a certain angle through the cooperation of the driving component and the resetting component, thereby simulating a zero-gravity state. This allows the passenger to evenly distribute the pressure on their body when sitting on the seat body, thus effectively improving the comfort and experience of sitting and making it highly practical.
[0029] 2. By opening ventilation holes on the support plate and connecting them to the car's air conditioning system, the seat body can be ventilated after adjustment. A driven plate is set to control the airflow of the ventilation holes, further improving the comfort of the seat body. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0041] This application discloses a zero-gravity seat adjustment mechanism. (Refer to...) Figure 1 A zero-gravity seat adjustment mechanism includes a support plate 1 and a seat body 2 disposed above the support plate 1. The support plate 1 includes an integrally formed horizontal plate 11 and an inclined plate 12. A protective plate 13 is integrally formed and connected to one side of the support plate 1, thereby reducing the probability of the passenger falling off the support plate 1 and effectively improving the safety of the zero-gravity seat of this application.
[0042] Reference Figure 1 and Figure 2 The surface of the horizontal plate 11 is connected by bolts to a rotating bracket 3 for mounting the seat body 2. The rotating bracket 3 includes a horizontal plate 31 and vertical plates 32 integrally formed at both ends of the horizontal plate 31. The seat body 2 is disposed between the vertical plates 32 on both sides. The rotating bracket 3 is provided with a driving component 4 for driving the seat body 2 to rotate.
[0043] Reference Figure 2 , Figure 3 and Figure 4 The driving component 4 includes a drive motor 41, a driving gear 42, a driven gear 43, two rotating plates 44, six limiting wheels 45, a connecting rod 46, and two rotating bearings 47. One vertical plate 32 corresponds to one rotating plate 44 and three limiting wheels 45.
[0044] Reference Figure 2 and Figure 3 The horizontal plate 31 has a drive cavity 311 for mounting the drive motor 41. The drive motor 41 is bolted to the inner wall of the drive cavity 311. One end of the connecting rod 46 is welded to the output shaft end wall of the drive motor 41, and the other end of the connecting rod 46 is inserted into the inner ring of one of the rotating bearings 47. This rotating bearing 47 is embedded in the inner wall of the other side of the drive cavity 311, and its outer ring is fixedly connected to the inner wall of the drive cavity 311 by adhesive. This allows the connecting rod 46 to form a rotatable connection with the inner wall of the drive cavity 311. The drive gear 42 is sleeved on the outer wall of the connecting rod 46, and another rotating bearing 47 is disposed between the drive gear 42 and the drive motor 41. This allows the connecting rod 46 to drive the drive gear 42 to rotate more smoothly, reducing resistance and thus improving the stability of the drive component 4.
[0045] Reference Figure 3 and Figure 4 The driven gear 43 is welded to the bottom wall of the seat body 2, and the driven gear 43 meshes with the driving gear 42. When the output shaft of the drive motor 41 drives the connecting rod 46 and the driving gear 42 to rotate, the seat body 2 can be rotated at a certain angle through the meshing relationship between the driving gear 42 and the driven gear 43. The rotating plate 44 is welded to the side wall of the seat body 2 facing the corresponding vertical plate 32. The side wall of the rotating plate 44 facing the vertical plate 32 has a drive groove 441. The drive groove 441 is arc-shaped and the drive... The curvature of the groove 441 is consistent with the direction of rotation of the seat body 2. One end of the limiting wheel 45 is connected to the corresponding vertical plate 32 by bolts, and the other end is inserted into the drive groove 441 of the corresponding rotating plate 44 and abuts against the inner wall of the drive groove 441. Thus, when the seat body 2 drives the rotating plate 44 to rotate, the seat body 2 is limited by the abutting relationship between the limiting wheel 45 and the inner wall of the drive groove 441, thereby effectively reducing the probability of the seat body 2 falling off the rotating bracket 3 and effectively improving the safety of the seat body 2 when adjusting to zero gravity.
[0046] Reference Figure 2 The seat body 2 is bolted to the side facing the inclined plate 12 with an adjustment tube 21. An adjustment rod 22 is slidably connected inside the adjustment tube 21. An adjustment groove 121 is opened on the side of the inclined plate 12 facing the seat body 2. The length direction of the adjustment groove 121 is consistent with the length direction of the inclined plate 12. One end of the adjustment rod 22 is inserted into the adjustment groove 121 and abuts against the bottom wall of the adjustment groove 121. The adjustment rod 22 can slide inside the adjustment tube 21. The adjustment rod 22 is hollow inside and is provided with a reset member 5 for driving the adjustment rod 22 to slide inside the adjustment tube 21. The reset member 5 helps to assist in the adjustment and reset of the seat body 2.
[0047] Reference Figure 2 , Figure 5 and Figure 6 The reset component 5 includes a mounting plate 51, a reset sleeve 52, a sliding rod 53, a fixing rod 54, a reset cable 55, a reset motor 56, and a winding wheel 57. The mounting plate 51 is connected to the seat body 2 by bolts. One end of the reset sleeve 52 passes through the mounting plate 51 and is connected to the mounting plate 51 by adhesive. The other end of the reset sleeve 52 is inserted into the adjusting tube 21. A buffer pad 521 is glued to the end of the reset sleeve 52 facing away from the seat body 2. One end of the sliding rod 53 passes through the buffer pad 521 and is inserted into the inner wall of the reset sleeve 52. The sliding rod 53 can slide along the length of the reset sleeve 52. The outer wall of the end of the sliding rod 53 away from the reset sleeve 52 is integrally formed with a limiting piece 532. The limiting piece 532 is connected to the inner wall of the adjusting rod 22 by adhesive and can drive the adjusting rod 22 to slide. After the limiting piece 532 slides, it can abut against the buffer pad 521, thereby preventing the sliding rod 53 from sliding excessively and entering the reset sleeve 52. In this embodiment, the buffer pad 521 is made of rubber, which can effectively reduce the wear between the components of the reset part 5 and extend its service life.
[0048] Reference Figure 2 , Figure 5 and Figure 6 The fixing rod 54 is glued to the surface of the buffer pad 521. Both the fixing rod 54 and the sliding rod 53 are hollow rods. The reset cable 55 includes a cable 551 and terminals 552 connected to both ends of the cable 551. The outer wall of the sliding rod 53 has two snap-fit holes 531 for the terminals 552 to snap into each other. The snap-fit holes 531 are connected to the hollow part inside the sliding rod 53. The end of the fixing rod 54 facing away from the buffer pad 521 is rotatably connected to a guide wheel 541. The reset motor 56 is bolted to the side of the mounting plate 51 facing away from the reset sleeve 52. The winding wheel 57 is fitted onto the reset sleeve by a key connection. The outer wall of the output shaft of the motor 56 has a reset hole 511 through which the mounting plate 51 passes along the thickness direction, allowing the cable 551 to pass through. The cable 551 passes through the snap-fit hole 531, the sliding rod 53, the reset sleeve 52, the winding wheel 57, the reset hole 511, the fixing rod 54, the guide wheel 541 and extends into another snap-fit hole 531. When the output shaft of the reset motor 56 rotates, it will pull or release the cable 551, so that the sliding rod 53 can slide along the length direction of the reset sleeve 52, thereby driving the adjusting rod 22 to move, which also facilitates the stable reset of the seat body 2.
[0049] Reference Figure 1 and Figure 7The inclined plate 12 has four ventilation holes 122 extending through it along the thickness direction. The ventilation holes 122 are divided into two groups and are located on both sides of the adjustment groove 121. The ventilation holes 122 can be used to connect to the air conditioning system inside the car. After the seat body 2 completes the zero-gravity adjustment, the seat body 2 forms a ventilated mode, further improving the comfort of the zero-gravity seat of this application.
[0050] Reference Figure 1 , Figure 7 and Figure 8 Four driven plates 6 are slidably connected to the side of the inclined plate 12 away from the seat body 2. Each driven plate 6 corresponds to a vent 122. Two driven plates 6 on the same side are connected by two connecting rods 61 by welding. The driven plates 6 can slide along the length direction of the inclined plate 12. A driven groove 123 is opened through the inner wall of the adjustment groove 121 along the length direction. A drive rod 221 is integrally formed on the outer wall of the adjustment rod 22. The drive rod 221 passes through the driven groove 123 and is connected to the outer wall of the driven plate 6 by welding. Thus, the driven plate 6 can be driven to make corresponding sliding adjustments during the sliding process of the adjustment rod 22.
[0051] Reference Figure 1 , Figure 8 and Figure 9 A sealing groove 65 is provided on the side of the driven plate 6 facing the vent 122. Several compression springs 66 are glued to the bottom wall of the sealing groove 65. A hemispherical sealing clip 67 is glued to the end of the compression springs 66 away from the bottom wall of the sealing groove 65. The sealing clip 67 can be inserted into the vent 122 to prevent foreign objects from entering the vent 122 and causing blockage of the vent 122.
[0052] Reference Figure 1 , Figure 8 and Figure 9 The driven plate 6 has a flow hole 62 along its thickness direction. After sliding with the driven plate 6, the flow hole 62 can eventually be aligned with the vent hole 122, so that the air conditioning air inside the car can circulate. Two sliding blocks 7 are sleeved on the connecting rod 61. The sliding blocks 7 can slide along the length direction of the connecting rod 61. Each side wall of the driven plate 6 that is close to each other is connected to a miniature cylinder 8 by adhesive. The piston rod of the miniature cylinder 8 is connected to the side wall of the corresponding sliding block 7 by adhesive, so that the sliding block 7 can be driven to slide along the length direction of the connecting rod 61.
[0053] Reference Figure 1 , Figure 8 and Figure 9Each sliding block 7 has a rotating rod 71 hinged to its surface. The driven plate 6 has a semi-circular arc groove 63 on its surface. The arc groove 63 is coaxial with the flow hole 62, and the diameter of the arc groove 63 is larger than the diameter of the flow hole 62. The end of the rotating rod 71 facing away from the sliding block 7 is connected to a rotating rod 72 by welding. One end of the rotating rod 72 is inserted into the arc groove 63 and can slide along the length of the arc groove 63. The side of the flow hole 62 facing away from the inclined plate 12 is hinged to two semi-circular opening and closing plates 64. The other end of the opening and closing plates 64 is sleeved on the outer wall of the corresponding rotating rod 72 and can move closer to each other as the rotating rod 72 moves, thereby adjusting the opening size of the flow hole 62. This improves the flexibility of this application, allowing passengers to adjust the size of the airflow in the vent 122 according to the actual situation, further improving the comfort of the zero-gravity seat of this application.
[0054] The implementation principle of the zero-gravity seat adjustment mechanism in this application embodiment is as follows: When the seat body 2 needs to be adjusted in angle, the drive motor 41 is started. The output shaft of the drive motor 41 drives the active gear 42 to rotate. The driven gear 43, through the meshing relationship with the active gear 42, forms a certain angle of deflection under the restriction of the rotating plate 44 and the limiting wheel 45. During the deflection of the seat body 2, the reset motor 56 rotates in the forward direction, and pulls the reset cable 55 through the winding wheel 57, so that the sliding rod 53 can drive the adjustment rod 22 to be inserted into the adjustment tube 21, so that the adjustment rod 22 can slide along the length direction of the adjustment groove 121. This allows the seat body 2 to simulate a zero-gravity state, so that the passenger can be in a state of temporary weightlessness, dispersing the pressure on various parts of the body, thereby improving the riding comfort.
[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
