Description

Technical Field

[0001] The embodiments of the present application relate to the field of seat technology, and in particular to a zero-gravity seat and vehicle. Background Art

[0002] Zero-gravity seats are designed to put passengers in a relaxed state similar to weightlessness in outer space. Zero-gravity seats can fully fit the human body, reduce gravity concentration, reduce the pressure on the human body, and significantly improve the riding comfort of passengers.

[0003] Existing zero-gravity seats require passengers to manually turn on and off the zero-gravity state, such as pressing a control button to make the zero-gravity seat enter or exit the zero-gravity state. Such operations are relatively cumbersome. In addition, since the passenger's body position changes before and after the seat is adjusted to the zero-gravity state, the relative position of the control button also changes accordingly. Therefore, after the seat enters the zero-gravity state, it is inconvenient for the passenger to operate the control button, resulting in a poor user experience of the zero-gravity seat.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0041] The embodiment of the present application provides a vehicle. For a vehicle, seats are generally arranged inside. In order to improve the riding comfort of the vehicle, the seats of some vehicles have a zero-gravity adjustment mode, thereby forming a zero-gravity seat, which is generally installed in the co-pilot seat.

[0042] Reference Figures 1 to 3 The zero-gravity seat mainly includes: a seat body 1, a detection unit 2, a controller 3, a drive component 4 and an actuator component 5. The detection unit 2 is used to detect the state of the passenger on the seat body 1. The controller 3 is electrically connected to the detection unit 2 and is used to receive the passenger state signal of the detection unit 2. The drive component 4 is electrically connected to the controller 3. The actuator component 5 is arranged in the seat body 1 and connected to the drive component 4. Based on the passenger state signal, the controller 3 controls the drive component 4 to drive the actuator component 5 to make the seat body 1 enter the zero-gravity state.

[0043] The embodiment of the present application uses a detection unit 2 to detect the state of the passenger on the seat body 1, and sends a passenger state signal to the controller 3. When the passenger leans on the seat body 1, the controller 3 controls the driving component 4 to drive the execution component 5, and the execution component 5 automatically adjusts the seat body 1 to enter a zero gravity state, without manual operation, which is convenient and fast, and has a good user experience.

[0044] It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the car model, the car in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other models. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.

[0045] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.

[0046] On this basis, refer to Figures 1 to 3 The embodiment of the present application also provides a zero-gravity chair, which mainly includes: a seat body 1, a detection unit 2, a controller 3, a drive component 4 and an actuator component 5. The detection unit 2 is used to detect the state of a passenger on the seat body 1. The controller 3 is electrically connected to the detection unit 2, and is used to receive a passenger state signal from the detection unit 2. The drive component 4 is electrically connected to the controller 3. The actuator component 5 is disposed in the seat body 1 and is connected to the drive component 4. Based on the passenger state signal, the controller 3 controls the drive component 4 to drive the actuator component 5 to make the seat body 1 enter a zero-gravity state.

[0047] The zero-gravity seat provided in the embodiment of the present application uses a detection unit 2 to detect the state of a passenger on the seat body 1, and sends a passenger state signal to a controller 3. When the passenger leans on the seat body 1, the controller 3 controls the driving component 4 to drive the execution component 5, and the execution component 5 automatically adjusts the seat body 1 to enter a zero-gravity state, without manual operation, which is convenient and fast, and has a good user experience.

[0048] It should be noted that the seat body 1 needs multiple components to work together to enter the zero gravity state. The specific setting form can be selected according to actual needs. For example, the backrest 101 is horizontally backward, the seat body 1 is tilted downward, and the footrest is rotated upward. The detection unit 2, the controller 3, the drive component 4 and the execution component 5 can all be powered by the power supply in the vehicle.

[0049] It should be noted that, in the embodiment of the present application, the controller 3 can select any existing controller as needed. For example, the controller 3 can select an existing controller such as a microcontroller unit (MCU), a central processing unit, an electronic controller unit (ECU), etc. Of course, other conventional controllers can also be selected as needed. This embodiment of the present application is not limited to this.

[0050] In addition, in the embodiment of the present application, there is no limitation on the detection unit 2 , as long as the detection unit 2 can detect the status of the passenger on the seat body 1 .

[0051] In some embodiments of the present application, the passenger state signal includes at least a leaning signal and a standing signal. In response to the leaning signal, the controller 3 controls the drive component 4 to drive the actuator component 5 to put the seat body 1 into a zero gravity state. In response to the standing signal, the controller 3 controls the drive component 4 to drive the actuator component 5 to reset the seat body 1.

[0052] It is understandable that the passenger status signal can also select other conventional action status signals as needed. The controller 3 can control the driving component 4 to drive the execution component 5 to implement the corresponding action according to the corresponding passenger status signal. In this regard, the embodiment of the present application does not impose too many restrictions.

[0053] Further, in some embodiments of the present application, Figure 1 and Figure 2 As shown, the seat body 1 includes a backrest 101. The backrest 101 is used to provide back support for the passenger when resting. The detection unit 2 includes a pressure sensor 201. The pressure sensor 201 is arranged on the backrest 101. When the passenger leans on the backrest 101, the pressure sensor 201 detects the pressure signal borne by the backrest 101 and sends it to the controller 3. Based on the pressure signal of the pressure sensor 201, the controller 3 controls the drive component 4 to drive the actuator component 5 so that the backrest 101 falls back to the zero gravity position or tilts forward to reset.

[0054] The pressure sensor 201 provided in the embodiment of the present application can collect the force of the passenger leaning against the backrest 101. The passenger state can be judged based on the pressure signal of the backrest 101 detected by the pressure sensor 201. The controller 3 automatically controls the drive component 4 to drive the actuator component 5 based on the size of the pressure signal sent by the pressure sensor 201, and the actuator component 5 drives the backrest 101 to fall back to the zero gravity position or tilt forward to reset, which is convenient and quick. Compared with the traditional zero gravity seat, the control button is omitted and the structure is simpler.

[0055] Furthermore, in some embodiments of the present application, Figure 2 As shown, the driving assembly 4 includes a backrest driving member 401. The actuating assembly 5 includes a backrest actuating member. The backrest actuating member is arranged on the backrest 101, and the backrest driving member 401 is connected to the backrest actuating member.

[0056] In response to the pressure signal of the pressure sensor 201 reaching the preset pressure value, the controller 3 controls the backrest driving member 401 to drive the backrest actuator to make the backrest 101 fall back to the zero gravity position. When the passenger needs to activate the zero gravity state of the seat body 1, he only needs to lean on the backrest 101 and apply pressure to the preset pressure value. The backrest 101 can be automatically controlled to fall back to the zero gravity position.

[0057] In response to the pressure signal of the pressure sensor 201 reaching the reset pressure value, the controller 3 controls the backrest driving member 401 to drive the backrest actuator to reset the backrest 101. After the passenger stands up, the pressure signal of the pressure sensor 201 decreases rapidly and reaches the reset pressure value, so that the backrest 101 can be automatically tilted forward to reset, so as to prevent the seat body 1 from occupying the rear space in the vehicle.

[0058] It should be noted that when the pressure signal of the pressure sensor 201 reaches the preset pressure value, it can be regarded as a leaning signal. The preset pressure value can be set according to the needs of the passenger. When the pressure signal of the pressure sensor 201 reaches the reset pressure value, it can be regarded as a standing signal. The reset pressure value is generally close to zero.

[0059] In addition, the backrest driving member 401 and the backrest actuator can adopt any existing structure. For example, the backrest driving member 401 can adopt a driving motor, which has a low cost. The backrest actuator can adopt a recliner, which has a simple structure and is easy to install.

[0060] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the detection unit 2 also includes a displacement detector 202. The displacement detector 202 is used to detect whether the backrest 101 is tilted back to the zero gravity position. The controller 3 controls the drive component 4 to drive the actuator component 5 in response to the backrest position signal of the displacement detector 202, so that the seat body 1 enters the zero gravity state.

[0061] The displacement detector 202 is used to detect the position of the backrest 101, and sends a backrest position signal to the controller 3 when the backrest 101 falls back to the zero gravity position. The controller 3 controls the drive component 4 to drive the actuator component 5 to make the seat body 1 enter the zero gravity state. The embodiment of the present application first adjusts the backrest 101 to the zero gravity position, and then adjusts the various components on the seat body 1 to gradually adjust to the zero gravity state, with gentle movements to further improve the passenger's experience.

[0062] In some embodiments of the present application, Figure 2 As shown, the drive assembly 4 also includes a zero-gravity drive member 402. The actuator assembly 5 also includes a zero-gravity actuator. The zero-gravity actuator is connected to the zero-gravity drive member 402. The controller 3 controls the zero-gravity drive member 402 to drive the zero-gravity actuator in response to the backrest position signal, so that the seat body 1 enters a zero-gravity state, without the need for manual operation by the passenger, and is convenient to use. In addition, the controller 3 can also control the backrest drive member 401 to lock in response to the backrest position signal to fix the backrest 101 in the zero-gravity position.

[0063] It should be noted that, in the embodiment of the present application, the seat body 1 enters a zero-gravity state requiring multiple driving members to control multiple actuators respectively, so that multiple components on the seat body 1 can act in coordination. For the convenience of description, in the embodiment of the present application, the above-mentioned multiple driving members are collectively referred to as zero-gravity driving members 402, and the multiple actuators are collectively referred to as zero-gravity actuators.

[0064] In addition, the embodiments of the present application do not limit the zero-gravity drive member 402 and the zero-gravity actuator. Any existing structure can be selected as needed. For example, when the seat body 1 enters the zero-gravity state, the rubber support rotates upward. The zero-gravity actuator includes a rubber support motor. The zero-gravity actuator includes a rubber support rotating mechanism. The controller 3 controls the rubber support motor to drive the rubber support rotating mechanism, and the rubber support rotating mechanism drives the rubber support to rotate to the corresponding position of the zero-gravity state. After the seat body 1 enters the zero-gravity state, the rubber support motor reaches a stalled state to fix the position of the rubber support.

[0065] Furthermore, in some embodiments of the present application, the controller 3 controls the zero-gravity driving element 402 to drive the zero-gravity actuator in response to the pressure signal of the pressure sensor 201 reaching the reset pressure value, so as to reset the seat body 1. In the embodiment of the present application, after the passenger stands up, the pressure signal of the pressure sensor 201 decreases rapidly and reaches the reset pressure value, and the seat body 1 can also be automatically restored from the zero-gravity state to the initial position so that the passenger can sit in the seat normally.

[0066] Further, in some embodiments of the present application, Figure 1 and Figure 2As shown, the displacement detector 202 is a laser sensor, which is suitable for being installed on the door panel of the vehicle and can emit laser to the zero gravity position. The laser sensor can be used to quickly identify whether the backrest 101 is tilted back to the zero gravity position, and the use cost is low.

[0067] In some other embodiments of the present application, the displacement detector 202 may also select other conventional sensors, such as a Hall sensor, etc., as needed.

[0068] In some embodiments of the present application, the detection unit 2 can also be used to detect whether the seat body 1 enters a zero gravity state, so that the controller 3 controls the seat body 1 to maintain the zero gravity state. The specific detection means can adopt any existing method, and the embodiments of the present application do not impose too many restrictions on this.

[0069] In some embodiments of the present application, Figure 1 and Figure 3 As shown, the zero-gravity seat further includes a projection device 6. The projection device 6 is disposed on the backrest 101 and is electrically connected to the controller 3. When the seat body 1 enters the zero-gravity state, the controller 3 controls the projection device 6 to turn on. By arranging the projection device 6 on the backrest 101 and associating the projection device 6 with the zero-gravity state of the seat body 1, the projection device 6 can be started when the seat body 1 enters the zero-gravity state, and the projection image can be projected onto the roof area inside the vehicle, so as to enrich the entertainment of passengers in the zero-gravity state.

[0070] Furthermore, in some embodiments of the present application, the zero-gravity chair further includes a voice recognition module. The voice recognition module is electrically connected to the controller 3. The passenger can control the driving component 4 to drive the execution component 5 through the voice recognition module to make the seat body 1 enter the zero-gravity state or reset. The passenger can also control the opening and closing of the projection device 6 through the voice recognition module, and the voice control method is more convenient to further improve the passenger's experience.

[0071] The working principle of the embodiment of the present application is as follows:

[0072] The passenger leans against the backrest 101 and applies pressure. When the pressure sensor 201 detects that the pressure signal reaches the preset pressure value, the controller 3 first controls the backrest drive 401 to drive the backrest actuator, and the backrest actuator drives the backrest 101 to fall backward. When the backrest 101 falls backward to the zero gravity position, the backrest 101 blocks the laser emitted by the laser sensor. The laser sensor sends the backrest position signal to the controller 3. The controller 3 controls the backrest drive 401 to lock, and at the same time controls the zero gravity drive 402 to drive the zero gravity actuator, and the zero gravity actuator drives the seat body 1 to enter the zero gravity state. In addition, the controller 3 also controls the projection device 6 to start.

[0073] After the passenger stands up, the pressure signal decreases rapidly and reaches the reset pressure value. The controller 3 controls the backrest drive 401 to drive the backrest actuator, which drives the backrest 101 to tilt forward and reset. At the same time, the zero gravity drive 402 is controlled to drive the zero gravity actuator, which drives all components on the seat body 1 to reset and exit the zero gravity state. In addition, the controller 3 controls the projection device 6 to turn off.

[0074] The serial numbers of the embodiments of the present application are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
