In view of the above problems, embodiments of the present invention provide an electrically controlled suspension for a vehicle seat and a vehicle seat, which can be applied to various seats of vehicles. To facilitate understanding of the present embodiment, a vehicle seat electrically controlled suspension disclosed in the present embodiment of the invention will be described in detail first, and as shown in fig. 1, the vehicle seat electrically controlled suspension includes: a suspension control device 101, a distance sensor 102, and an air spring 103; the suspension control device 101 is connected to a distance sensor 102 and an air spring 103.

With respect to the above embodiment, the present invention also provides another electrically controlled suspension for a vehicle seat, which is implemented on the basis of the above electrically controlled suspension for a vehicle seat, as shown in fig. 2, and includes a suspension control device 101, a distance sensor 102, and an air spring 103.
The electric control suspension for the vehicle seat further comprises: an intake relay 204 connected to the suspension control device 101, and an intake solenoid valve 205 connected to the air spring 103 through an intake pipe; wherein, the air inlet intermediate relay 204 is connected with an air inlet electromagnetic valve 205; a deflation relay 206 connected to the suspension control device 101, and a deflation solenoid valve 207 connected to the air spring 103 through an exhaust pipe; the air release relay 206 is connected to an air release solenoid 207.
The inlet relay 204 and the outlet relay 206 are used to transmit signals and control multiple circuits simultaneously, and can also be used to directly control a small-capacity motor or other electric actuators. In the present embodiment, the air intake relay 204 is an electric actuator used when the suspension control device 101 controls the air spring 103 to inflate, and the air release relay 206 is an electric actuator used when the suspension control device 101 controls the air spring 103 to deflate; the electromagnetic valve is an industrial device controlled by electromagnetism, is an automatic basic element for controlling fluid, belongs to an actuator, and is not limited to hydraulic pressure and pneumatic pressure. Used in industrial control systems to regulate the direction, flow, velocity and other parameters of a medium. There are many types of solenoid valves, with different solenoid valves functioning at different locations in the control system, the most common being one-way valves, safety valves, directional control valves, speed control valves, etc. In the present embodiment, the air intake solenoid valve 205 is used to open or close the air intake passage of the air spring 103, and the air discharge solenoid valve 207 is used to open or close the air discharge passage of the air spring 103.
Specifically, when the height indicated by the seat adjustment instruction is greater than the distance sent by the distance sensor 102, the suspension control device 101 sends an intake electric signal to the intake intermediate relay 204; the air inlet intermediate relay 204 controls the opening of the air inlet electromagnetic valve 205 according to the received air inlet electric signal, so that the air inlet electromagnetic valve 205 is opened to charge the air spring 103. When the height indicated by the seat adjustment instruction is smaller than the distance sent by the distance sensor 102, the suspension control device 101 sends a deflation electric signal to the deflation relay 206; the air release intermediate relay 206 controls the air release solenoid valve 207 to open according to the received air release electric signal, so that the air spring 103 is released after the air release solenoid valve 207 is opened.

Through the operation, the user can get off the vehicle more conveniently and quickly.
The electrically controlled seat suspension further includes a seating sensor 208; the seating sensor 208 is provided in the seat cushion, and the seating sensor 208 is connected to the suspension control device 101 in communication; the seating sensor 208 is configured to monitor status data of the seat cushion and send the status data to the suspension control device 101; wherein the status data is indicative of whether an object is present on the seat cushion.
Specifically, the seating sensor 208 is a car seat SBR sensor, which is a thin film type contact sensor having contacts uniformly distributed on a force-receiving surface of a seat cushion, and the shape and sensitivity of the contact sensor are generally designed according to the shape, hardness, and tightness of a skin of the car seat cushion, and generates a trigger signal when the seat cushion receives a pressure from the outside. The SBR sensor of the car seat is applied to a passenger sensing system of the car seat, and in this embodiment, the SBR sensor of the car seat is mainly used for sensing whether a driver is out of a seat (i.e. whether a target object is on the seat cushion).
Specifically, the suspension control device 101 is further configured to store a seat adjustment command sent by an external device; specifically, during driving, the suspension control device 101 stores all seat adjustment commands (i.e., the gear heights) selected by the user into its own data recording text, and after the user gets on the vehicle and sits on the seat, the seating sensor 208 senses the presence of an object on the seat cushion, and then the seating sensor 208 transmits state data indicating the presence of the object on the seat cushion to the suspension control device 101, and the suspension control device 101 receives the state data indicating the presence of the object on the seat cushion, which is transmitted by the seating sensor 208, and then can control the air spring 103 to inflate or control the air spring 103 to deflate according to the stored seat adjustment commands.
Specifically, the operation of controlling the air spring 103 to inflate or deflate by the suspension control device 101 can be determined by a user after selecting a height gear (i.e. by receiving a seat adjustment command sent by the external device) at a vehicle control computer. Further, in the present embodiment, when a user gets on and sits down (that is, after the seating sensor 208 detects status data of an object on the seat cushion), the seating sensor 208 transmits the status data to the suspension control device 101, the suspension control device 101 determines a seat adjustment command (that is, a gear height) selected last time according to all seat adjustment commands (that is, gear heights) in a data recording text of the data, the seat adjustment command (that is, the gear height) selected last time is a seat adjustment command (that is, a gear height) selected last time when the suspension control device 101 receives a get-off command transmitted from an external device, and then the suspension control device 101 directly controls the air spring 103 to inflate according to the seat adjustment command (that is, the gear height), and a specific inflation control procedure is consistent with the above, and will not be described in detail herein.

In a concrete implementation, when a vehicle runs on a road, if the running road is bumpy, the vehicle seat height may shake up and down, in the process, the distance sensor 102 monitors the current distance between an upper frame and a lower frame of an electrically controlled suspension in real time, and sends the current distance to the suspension control device 101, the suspension control device 101 judges whether the current distance sent by the distance sensor 102 is within a suspension height range, if the height indicated by the current seat adjusting instruction is 50mm, the suspension height range set by a user is 10mm floating up and down based on the height indicated by the seat adjusting instruction, the suspension height range is 40 mm-60 mm, and the suspension control device 101 does not control the air inflation or deflation operation of the air spring 103 as long as the current distance sent by the distance sensor 102 is within 40 mm-60 mm, if the current distance is smaller than the minimum value of the suspension height range (namely smaller than 40mm), the suspension control device 101 controls the air spring 103 to inflate; if the distance is greater than the maximum value of the suspension height range (i.e., greater than 60mm), the suspension control device 101 controls the air spring 103 to deflate until the distance between the upper frame and the lower frame of the electrically controlled seat suspension (i.e., the height of the seat) vibrates within the suspension height range, and the suspension control device 101 sends a closing signal to the air inlet solenoid valve 205 and the air outlet solenoid valve 207, at which time the vibration interval is locked. The operation process of inflating, deflating or sending the closing signal is the same as the above, and is not described herein. Through the operation, the air spring 103 can be prevented from being frequently inflated or deflated, and the service life of the device is ensured.
Further, after the air spring 103 is controlled to inflate or deflate by the suspension control device 101, so that the distance between the upper frame and the lower frame of the electronic control suspension is equal to the height indicated by the seat adjusting instruction, the distance sensor 102 is further configured to monitor the current distance between the upper frame and the lower frame of the electronic control suspension, and send the current distance to the suspension control device 101; the suspension control device 101 is configured to determine whether a current distance currently sent by the distance sensor is equal to a height indicated by the seat adjustment instruction, and if not, control the air spring 103 to inflate so that a current distance between an upper frame and a lower frame of the electrically controlled suspension is equal to the height indicated by the seat adjustment instruction.
In specific implementation, after the suspension control device 101 controls the air spring 103 to inflate or deflate so that the distance between the upper frame and the lower frame of the electrically controlled suspension is equal to the height indicated by the seat adjustment instruction, there may be a case where the air spring 103 is slightly deflated, at this time, the height of the electrically controlled suspension of the vehicle seat will slowly decrease, at this time, the distance sensor 102 monitors the current distance between the upper frame and the lower frame of the electrically controlled suspension and sends the current distance to the suspension control device 101, the suspension control device 101 determines whether the air spring 103 is deflated by determining whether the current distance is equal to the height indicated by the seat adjustment instruction, and when the current distance is not equal to the height indicated by the seat adjustment instruction, the air spring 103 is controlled to inflate so that the current distance between the upper frame and the lower frame of the electrically controlled suspension is equal to the height indicated by the seat adjustment instruction, the specific steps for controlling the air inflation of the air spring 103 are the same as those described above, and are not described herein again.
