Description

Technical Field

[0001] This invention relates to the field of business seating technology, specifically to a business seat that enables automatic opening and closing of partitions. Background Technology

[0002] High-speed rail seating is divided into three types: second class, first class, and business class. The business class seats have a rounded shape, with a modern milky white outer shell and a bright red genuine leather seat with a national feel inside. They can be used in three positions: sitting upright, sitting flat, and lying flat, and can be switched at will with the press of a button.

[0003] Traditional business seats cannot separate the passenger seating area, resulting in poor privacy. They also cannot automatically adjust the partition of the passenger seating area according to the passenger's needs. Therefore, it is necessary to design a business seat that can automatically open and close the partition. Summary of the Invention

[0004] The purpose of this invention is to provide a business chair that enables automatic opening and closing of partitions, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a business chair that realizes automatic opening and closing of the partition, including a chair body, a bar counter body, an operation display screen, a privacy cover, a partition body and a controller, wherein the chair body and the bar counter body are located inside the privacy cover, the operation display screen is located on the bar counter body, the partition body is located outside the privacy cover, and the controller is located on one side of the chair body.

[0006] The partition body includes a mounting plate connected to the privacy cover and a movable plate disposed on the mounting plate. The bottom of the mounting plate is provided with a moving mechanism for driving the movable plate to move.

[0007] The seat body is provided with a seat cushion, the seat cushion is provided with a pressure pad, and the seat cushion is provided with a gravity sensing mechanism that cooperates with the pressure pad. The gravity sensing mechanism is electrically connected to the moving mechanism. The moving mechanism is driven by the gravity sensing mechanism. When the gravity sensing mechanism senses that a passenger is sitting on the seat cushion, the moving mechanism works, causing the moving plate to move, thereby partitioning the space of the seat body area through the partition body.

[0008] An infrared sensor is provided on the side of the movable plate facing the seat body. The infrared sensor is electrically connected to the movable mechanism. A laser obstacle sensor is provided on the seat body. The laser obstacle sensor, gravity sensing mechanism and infrared sensor are all electrically connected to the controller. When the passenger moves away from the movable plate, the laser obstacle sensor works and senses that there is no obstacle in front of the seat body. At this time, the movable plate is in the normally open state.

[0009] In a further embodiment, the gravity sensing mechanism includes a pressure plate disposed within the seat cushion, the bottom of the pressure pad extending into the seat cushion and connected to the pressure plate, a gravity sensing plate being disposed at the connection point between the bottom of the pressure pad and the pressure plate, a main control board electrically connected to the controller being disposed below the pressure plate, the main control board being electrically connected to the gravity sensing plate via a first transmission line, and the main control board being electrically connected to the moving mechanism via a second transmission line.

[0010] In a further embodiment, the moving mechanism includes a servo motor mounted on a mounting plate, the output end of the servo motor being connected to a guide screw, a driver being electrically connected to one side of the servo motor, the driver being electrically connected to a second transmission line, a sliding seat being threaded onto the guide screw, and the sliding seat being connected to the moving plate through a stabilizing mechanism.

[0011] In a further embodiment, the stabilizing mechanism includes a connecting corner block fixed on a sliding seat, the connecting corner block being connected to a guide plate, the guide plate being connected to a moving plate via a lower connecting plate, a lower guide block being fixed on the connecting corner block, and a lower limit slide rail cooperating with the lower guide block being provided on the mounting plate.

[0012] In a further embodiment, a slider is fixed at the bottom of the sliding seat, and a groove is provided on the mounting plate to slide with the slider. A limiting rod is provided on the groove to pass through the slider, and the slider slides with the limiting rod.

[0013] In a further embodiment, the infrared sensor head is electrically connected to the driver, and the laser obstacle sensor is electrically connected to the gravity sensor plate. When the passenger's buttocks leave the seat body, the gravity sensor plate no longer senses pressure. At this time, the gravity sensor plate transmits a signal to the infrared sensor head, which then operates to sense passengers approaching the moving plate. When the passenger approaches the moving plate at a certain distance, the infrared sensor head transmits a signal to the driver, which drives the moving plate to move, thereby opening the partition body. When the passenger moves away from the moving plate, the laser obstacle sensor operates to sense whether there are passengers in the space in front of the seat body. When the laser obstacle sensor detects no passengers, the moving plate is in the normally open state.

[0014] In a further embodiment, the main control board includes a main control module, which is electrically connected to an information processing module. The information processing module is electrically connected to a gravity sensing plate and an infrared sensing head, respectively. The information processing module is electrically connected to an output control module, and the output control module is electrically connected to a driver.

[0015] In a further embodiment, an upper connecting plate is fixed to the top of the movable plate, an upper guide block is fixed to the upper connecting plate, and an upper limit slide rail that cooperates with the upper guide block is provided on the mounting plate.

[0016] In a further embodiment, the bottom of the pressure plate is provided with several pressure-bearing buffers, the seat cushion is provided with guide rods, the pressure plate is provided with guide holes that cooperate with the guide rods, and the seat cushion is provided with guide grooves that cooperate with the pressure plate.

[0017] Compared with the prior art, the beneficial effects achieved by this invention are as follows: When there are no passengers on the seat body, the movable plate on the partition body is in an unextended state. When a passenger sits on the seat body, the gravity sensing mechanism senses the pressure, and the movable mechanism works, causing the movable plate to extend, thus partitioning the space of the seat body area through the partition body. When the passenger gets up and leaves the seat body, the gravity sensing mechanism no longer senses the pressure. At this time, the gravity sensing plate transmits a signal to the infrared sensor, which works to sense passengers approaching the movable plate. When a passenger approaches the movable plate at a certain distance, the infrared sensor transmits a signal to the movable mechanism, which drives the movable plate to retract, no longer partitioning the space of the seat body area. When the passenger moves away from the movable plate, the laser obstacle sensor works to sense whether there are passengers in the space in front of the seat body. When the laser obstacle sensor detects no passengers, the movable plate is in a normally open state, facilitating the entry of subsequent passengers and allowing for automatic adjustment of the partition space of the seat area according to the passenger's seating needs, thus ensuring privacy.

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0026] Please see Figures 1-7 The present invention provides a technical solution: a business chair that realizes automatic opening and closing of partitions, including a chair body 1, a bar counter body 2, an operation display screen 3, a privacy cover 4, a partition body 5 and a controller. The chair body 1 and the bar counter body 2 are located inside the privacy cover 4, the operation display screen 3 is located on the bar counter body 2, the partition body 5 is located outside the privacy cover 4, and the controller is located on one side of the chair body 1.

[0027] The partition body 5 includes a mounting plate 14 connected to the privacy cover 4 and a movable plate 15 disposed on the mounting plate 14. The bottom of the mounting plate 14 is provided with a moving mechanism for driving the movable plate 15 to move.

[0028] The seat body 1 is provided with a seat cushion 6, and a pressure pad 7 is provided on the seat cushion 6. A gravity sensing mechanism that cooperates with the pressure pad 7 is provided inside the seat cushion 6. The gravity sensing mechanism is electrically connected to the moving mechanism. The moving mechanism is driven by the gravity sensing mechanism. When the gravity sensing mechanism senses that a passenger is sitting on the seat cushion 6, the moving mechanism works, causing the moving plate 15 to move, and the partition body 5 partitions the space of the seat body 1 area.

[0029] An infrared sensor 29 is provided on the side of the movable plate 15 facing the seat body 1. The infrared sensor 29 is electrically connected to the movable mechanism. A laser obstacle sensor is provided on the seat body 1. The laser obstacle sensor, gravity sensing mechanism and infrared sensor 29 are all electrically connected to the controller. When the passenger moves away from the movable plate 15, the laser obstacle sensor works and senses that there is no obstacle in front of the seat body 1. At this time, the movable plate 15 is in the normally open state.

[0030] Through the above technical solution, when there is no passenger on the seat body 1, the movable plate 15 on the partition body 5 is in a non-extended state. When a passenger sits on the seat body 1, the gravity sensing mechanism senses pressure, the movable mechanism works, and the movable plate 15 extends, thus partitioning the space of the seat body 1 area through the partition body 5. When the passenger gets up and leaves the seat body 1, the gravity sensing mechanism no longer senses pressure. At this time, the gravity sensing plate 9 transmits a signal to the infrared sensor 29, and the infrared sensor 29 works, sensing passengers approaching the movable plate 15. When a passenger approaches the movable panel 15 at a certain distance, the infrared sensor 29 transmits a signal to the moving mechanism, which then drives the movable panel 15 to retract, no longer partitioning the space in the seat body 1 area. When the passenger moves away from the movable panel 15, the laser obstacle sensor activates, detecting whether there are passengers in the space in front of the seat body 1. When the laser obstacle sensor detects no passengers, the movable panel 15 remains open, facilitating subsequent passenger entry and allowing for automatic adjustment of the partition in the seat area according to passenger needs, thus ensuring privacy.

[0031] In a further embodiment, the gravity sensing mechanism includes a pressure plate 8 disposed within the seat cushion 6, a pressure pad 7 extending into the seat cushion 6 and connected to the pressure plate 8, a gravity sensing plate 9 disposed at the connection between the bottom of the pressure pad 7 and the pressure plate 8, and a main control board 11 electrically connected to the controller disposed below the pressure plate 8. The main control board 11 is electrically connected to the gravity sensing plate 9 via a first transmission line 12, and the main control board 11 is electrically connected to the moving mechanism via a second transmission line 13.

[0032] Through the above technical solution, the seat cushion 6, together with the gravity sensing plate 9, senses the pressure and transmits the signal to the main control board 11 through the first transmission line 12. The main control board 11, together with the second transmission line 13, transmits the signal to the moving mechanism.

[0033] In a further embodiment, the moving mechanism includes a servo motor 22 mounted on the mounting plate 14. The output end of the servo motor 22 is connected to the guide screw 23. A driver 24 is electrically connected to one side of the servo motor 22. The driver 24 is electrically connected to the second transmission line 13. A sliding seat 21 is threaded onto the guide screw 23. The sliding seat 21 is connected to the moving plate 15 through a stabilizing mechanism.

[0034] Through the above technical solution, the servo motor 22 is started and stopped by the driver 24 sensing the signal. The servo motor 22 drives the guide screw 23 to rotate, which in turn drives the sliding seat 21 to move on the guide screw 23, and then drives the moving plate 15 to extend or retract through the stabilizing mechanism.

[0035] In a further embodiment, the stabilizing mechanism includes a connecting corner block 20 fixed on the sliding seat 21. The connecting corner block 20 is connected to the guide plate 17. The guide plate 17 is connected to the moving plate 15 through the lower connecting plate 16. A lower guide block 18 is fixed on the connecting corner block 20. A lower limit slide rail 19 that cooperates with the lower guide block 18 is provided on the mounting plate 14.

[0036] Through the above technical solution, the connecting corner block 20, guide plate 17 and lower connecting plate 16 cooperate to facilitate the movement of the moving plate 15. The movement of the moving plate 15 causes the lower guide block 18 to slide on the lower limit slide rail 19, so that the moving plate 15 moves stably.

[0037] In a further embodiment, a slider 25 is fixed at the bottom of the sliding seat 21, and a groove is provided on the mounting plate 14 to slide with the slider 25. A limiting rod is provided on the groove to pass through the slider 25, and the slider 25 slides with the limiting rod.

[0038] Through the above technical solution, the sliding block 25 slides on the slide groove by moving the sliding block 21, and with the help of the limiting rod, the sliding block 21 moves stably.

[0039] In a further embodiment, the infrared sensor 29 is electrically connected to the driver 24, and the laser obstacle sensor is electrically connected to the gravity sensor plate 9. When the passenger's buttocks leave the seat body 1, the gravity sensor plate 9 no longer senses pressure. At this time, the gravity sensor plate 9 transmits a signal to the infrared sensor 29, and the infrared sensor 29 works. The infrared sensor 29 senses the passenger approaching the moving plate 15. When the passenger approaches the moving plate 15 at a certain distance, the infrared sensor 29 transmits a signal to the driver 24, and the driver 24 drives the moving plate 15 to move, thereby opening the partition body 5. When the passenger moves away from the moving plate 15, the laser obstacle sensor works. The laser obstacle sensor senses whether there is a passenger in the space in front of the seat body 1. When the laser obstacle sensor detects that there is no passenger, the moving plate 15 is in the normally open state.

[0040] Through the above technical solution, the infrared sensor 29, the driver 24, the laser obstacle sensor and the gravity sensor 9 work together to facilitate the retraction of the movable plate 15 when the passenger leaves the seat, thereby opening the partition body 5.

[0041] In a further embodiment, the main control board 11 includes a main control module, which is electrically connected to the information processing module. The information processing module is electrically connected to the gravity sensing plate 9 and the infrared sensing head 29, respectively. The information processing module is electrically connected to the output control module, and the output control module is electrically connected to the driver 24.

[0042] Through the above technical solution, the main control module and the information processing module work together to process the signals transmitted by the gravity sensor plate 9 and the infrared sensor head 29, and then the output control module realizes the opening and closing of the driver 24.

[0043] In a further embodiment, an upper connecting plate 26 is fixed to the top of the movable plate 15, an upper guide block 28 is fixed on the upper connecting plate 26, and an upper limit slide rail 27 that cooperates with the upper guide block 28 is provided on the mounting plate 14.

[0044] Through the above technical solution, the upper guide block 28 is driven to slide on the upper limit slide rail 27 by the movement of the moving plate 15, so that the movement of the moving plate 15 is stable.

[0045] In a further embodiment, the bottom of the pressure plate 8 is provided with a plurality of pressure-bearing buffers 10, the seat cushion 6 is provided with a guide rod, the pressure plate 8 is provided with a guide hole that cooperates with the guide rod, and the seat cushion 6 is provided with a guide groove that cooperates with the pressure plate 8.

[0046] Through the above technical solution, the pressure plate 8 is supported by the pressure-bearing buffer 10, and the guide rod and guide groove cooperate to make the pressure plate 8 move stably.

[0047] Working principle: When there is no passenger on the seat body 1, the movable plate 15 on the partition body 5 is in the closed state. When a passenger sits on the seat body 1, the seat cushion 6, in conjunction with the gravity sensor plate 9, senses the pressure and transmits the signal to the main control board 11 via the first transmission line 12. The main control board 11, in conjunction with the second transmission line 13, transmits the signal to the driver 24, causing the servo motor 22 to rotate forward, driving the guide screw 23 to rotate, which in turn drives the sliding seat 21 to move on the guide screw 23. Through the cooperation of the connecting corner block 20, the guide plate 17, and the lower connecting plate 16, the movable plate 15 extends, thus partitioning the space of the seat body 1 via the partition body 5. When the passenger gets up and leaves... When the seat body 1 is in use, the gravity sensor 9 no longer senses pressure. Instead, the laser obstacle sensor detects whether there is a passenger in front of the seat body 1. When the laser obstacle sensor detects no obstacle in front of the seat body 1, it sends a signal to the infrared sensor 29. The infrared sensor 29 then detects passengers approaching the moving plate 15. When a passenger approaches the moving plate 15 to a certain distance, the infrared sensor 29 sends a signal to the driver 24, which causes the servo motor 22 to reverse and drive the moving plate 15 to retract. This eliminates the partitioning of the seat body 1 area, allowing for automatic adjustment of the partitioning of the seat area according to the passenger's seating needs and ensuring privacy.

However, the present invention is not limited to the specific details of the above embodiments.
